          This Pooling and Servicing Agreement (this "Agreement") is dated and
effective as of June 12, 2006, among STRUCTURED ASSET SECURITIES CORPORATION II,
as Depositor, WACHOVIA BANK, NATIONAL ASSOCIATION, as Master Servicer, LNR
PARTNERS, INC., as Special Servicer, and LASALLE BANK NATIONAL ASSOCIATION, as
Trustee.

                             PRELIMINARY STATEMENT:

          The Depositor intends to sell the Certificates, which are to be issued
hereunder in multiple Classes and which in the aggregate will evidence the
entire beneficial ownership interest in the Trust Fund.

          As provided herein, the Trustee will elect to treat each Early
Defeasance Trust Mortgage Loan, if any, as the primary asset of a separate REMIC
for federal income tax purposes, and each such REMIC will be designated as a
"Loan REMIC". The Class R-LR Certificates (if issued in accordance with Section
2.06) will represent the sole class of "residual interests" in each and every
Loan REMIC, if any, for purposes of the REMIC Provisions under federal income
tax law. A separate Loan REMIC Regular Interest will, on the Closing Date, be
issued with respect to, and will thereafter relate to, each Early Defeasance
Trust Mortgage Loan, if any, included in a Loan REMIC. Each Loan REMIC Regular
Interest, if any, issued with respect to, and relating to, an Early Defeasance
Trust Mortgage Loan in a Loan REMIC, shall also relate to any successor REO
Trust Mortgage Loan with respect to such Early Defeasance Trust Mortgage Loan.
Each Loan REMIC Regular Interest, if any, shall: (i) bear a numeric designation
that is the same as the loan number for the related Early Defeasance Trust
Mortgage Loan set forth on the Trust Mortgage Loan Schedule; (ii) accrue
interest at the related per annum rate described in the definition of "Loan
REMIC Remittance Rate"; and (iii) have an initial Uncertificated Principal
Balance equal to the Cut-off Date Balance of the related Early Defeasance Trust
Mortgage Loan. The Legal Final Distribution Date of each Loan REMIC Regular
Interest, if any, is the Distribution Date immediately following the third
anniversary of the end of the remaining amortization term (as determined as of
the Closing Date) of the related Early Defeasance Trust Mortgage Loan. None of
the Loan REMIC Regular Interests (if issued in accordance with Section 2.06)
will be certificated. Notwithstanding the foregoing, however, if the Trust Fund
does not include Early Defeasance Trust Mortgage Loans, then (i) there will be
no Loan REMICs, (ii) neither the Class R-LR Certificates nor any Loan REMIC
Regular Interests will be issued and (iii) the provisions of Section 2.06(b)
will apply.

          As provided herein, the Trustee will elect to treat the segregated
pool of assets consisting of the Trust Mortgage Loans (exclusive of the Early
Defeasance Trust Mortgage Loans, if any, and exclusive of any collections of
Additional Interest on the ARD Trust Mortgage Loans, if any, after their
respective Anticipated Repayment Dates), any Loan REMIC Regular Interests and
certain other related assets subject to this Agreement as a REMIC for federal
income tax purposes, and such segregated pool of assets will be designated as
"REMIC I." The Class R-I Certificates will represent the sole class of "residual
interests" in REMIC I for purposes of the REMIC Provisions under federal income
tax law. Two separate REMIC I Regular Interests will, on the Closing Date, be
issued with respect to, and will thereafter relate to, each Split Trust Mortgage
Loan, and such REMIC I Regular Interests will bear the following alphabetic or
alphanumeric designations: (i) "HUD-A" and "HUD-B", respectively, in the case of
the 70 Hudson Street Trust Mortgage Loan; (ii) "AMLI-A" and "AMLI-B",
respectively, in the case of the AMLI of North Dallas Trust Mortgage Loan; (iii)
"FOM-A" and "FOM-B", respectively, in the case of the Fountains of Miramar Trust
Mortgage Loan; and (iv) "STUR-A" and "STUR-B", respectively, in the case of the
Sturbridge Commons Trust Mortgage Loan. In addition, a separate REMIC I Regular
Interest will, on the Closing Date, be issued with respect to, and will
thereafter relate to, each other Trust Mortgage



Loan included in REMIC I and each Loan REMIC Regular Interest, if any, included
in REMIC I. Each REMIC I Regular Interest issued with respect to, and relating
to, a Trust Mortgage Loan in REMIC I, shall also relate to any successor REO
Trust Mortgage Loan with respect to such Trust Mortgage Loan. Each REMIC I
Regular Interest issued with respect to, and relating to, any Loan REMIC Regular
Interest, shall also relate to the Early Defeasance Trust Mortgage Loan and any
successor REO Trust Mortgage Loan corresponding to such Loan REMIC Regular
Interest. Each REMIC I Regular Interest shall: (i) except as otherwise described
above with respect to each of the respective REMIC I Regular Interests that
correspond to a Split Trust Mortgage Loan, bear a numeric designation that is
the same as the loan number for the related Trust Mortgage Loan set forth on the
Trust Mortgage Loan Schedule; (ii) accrue interest at a per annum rate described
in the definition of "REMIC I Remittance Rate"; and (iii) have an initial
Uncertificated Principal Balance equal to (A) $75,000,000 in the case of REMIC I
Regular Interest HUD-A, (B) $49,000,000 in the case of REMIC I Regular Interest
HUD-B, (C) $26,801,000 in the case of REMIC I Regular Interest AMLI-A, (D)
$25,587,000 in the case of REMIC I Regular Interest AMLI-B, (E) $12,292,000 in
the case of REMIC I Regular Interest FOM-A, (F) $11,708,000 in the case of REMIC
I Regular Interest FOM-B, (G) $11,630,000 in the case of REMIC I Regular
Interest STUR-A, (H) $13,720,000 in the case of REMIC I Regular Interest STUR-B,
and (E) the Cut-off Date Balance of the related Trust Mortgage Loan in the case
of each other REMIC I Regular Interest. The Legal Final Distribution Date of
each of the REMIC I Regular Interests is the Distribution Date immediately
following the third anniversary of the end of the remaining amortization term
(as determined as of the Closing Date) of the related Trust Mortgage Loan. None
of the REMIC I Regular Interests will be certificated.

          As provided herein, the Trustee will elect to treat the segregated
pool of assets consisting of the REMIC I Regular Interests as a REMIC for
federal income tax purposes, and such segregated pool of assets will be
designated as "REMIC II". The Class R-II Certificates will represent the sole
class of "residual interests" in REMIC II for purposes of the REMIC Provisions
under federal income tax law. The Legal Final Distribution Date for each REMIC
II Regular Interest is the latest Rated Final Distribution Date. None of the
REMIC II Regular Interests will be certificated. Each REMIC II Regular Interest
shall accrue interest at a per annum rate described in the definition of "REMIC
II Remittance Rate". The following table sets forth the designation and the
initial Uncertificated Principal Balance for each of the REMIC II Regular
Interests.

          As provided herein, the Trustee will elect to treat the segregated
pool of assets consisting of the REMIC II Regular Interests as a REMIC for
federal income tax purposes, and such segregated pool of assets will be
designated as "REMIC III". The Class R-III Certificates will evidence the sole
class of "residual interests" in REMIC III for purposes of the REMIC Provisions
under federal income tax law. For federal income tax purposes, each Class of the
Regular Interest Certificates (exclusive of the Class X Certificates) and each
REMIC III Component of the Class X Certificates will be designated as a separate
"regular interest" in REMIC III. The Legal Final Distribution Date for each
Class of Regular Interest Certificates (exclusive of the Class X Certificates)
and each REMIC III Component of the Class X Certificates is the latest Rated
Final Distribution Date. Each Class of Regular Interest Certificates and each
REMIC III Component of the Class X Certificates will accrue interest at the per
annum rate described in the definition of "Pass-Through Rate." The following
table sets forth the Class designation and original Class Principal Balance for
each Class of the Regular Interest Certificates.

absence of actual knowledge of an error, rely on the allocation in such
remittance reports; and provided, further, that, if one or more Advances
previously made in respect of an REO Trust Mortgage Loan have been reimbursed
out of general collections of principal on the Mortgage Pool as one or more
Nonrecoverable Advances, then collections in respect of such REO Trust Mortgage
Loan available for application pursuant to clauses first through fourth of this
sentence shall instead be applied in the following order--(i) as a recovery of
accrued and unpaid interest on, and principal of, such REO Trust Mortgage Loan,
to the extent of any outstanding P&I Advances and unpaid Master Servicing Fees
in respect of such REO Trust Mortgage Loan, (ii) as a recovery of the item(s)
for which such previously reimbursed Nonrecoverable Advance(s) were made

comprising any Serviced Loan Combination become REO Mortgage Loans, amounts
(other than Loss of Value Payments deemed to constitute Liquidation Proceeds
with respect to the REO Trust Mortgage Loan in such Serviced Loan Combination
and other than Liquidation Proceeds resulting from the purchase of the Trust's
interest in any related REO Property pursuant to or as contemplated by Section
2.03) received with respect to such REO Mortgage Loans shall be applied to

shall not be applied in accordance with the foregoing provisions of this
definition unless and until such amounts are transferred to the Pool Custodial

Servicer, the Special Servicer, the Trustee or any Fiscal Agent in respect of

     Certificateholders or, in the case of a Serviced Non-Trust Mortgage Loan,
     the interests of the related Serviced Non-Trust Mortgage Loan Noteholder),
     and (ii) continues unremedied by the related Mortgagor, any related

     with the Servicing Standard, that (i) a default in the making of a Monthly
     Payment on such Serviced Mortgage Loan, including a Balloon Payment, is
     likely to occur and is likely to remain unremedied (without regard to any

     Trust Mortgage Loan, by the related Loan-Specific Class Representative
     exercising cure rights pursuant to this Agreement) for at least the
     applicable period contemplated by clause (a) of this definition or (ii) a
     default (other than as described in clause (a) of this definition and other
     than an Acceptable Insurance Default) is likely to occur under such
     Mortgage Loan that will materially impair the value of the related
     Mortgaged Property as security for such Serviced Mortgage Loan or otherwise
     materially adversely affect the interests of Certificateholders (or, in the
     case of a Serviced Non-Trust Mortgage Loan, the related Serviced Non-Trust

     insolvency, readjustment of debt, marshaling of assets and liabilities or
     similar proceedings, or for the winding-up or liquidation of its affairs,
     shall have been entered against the related Mortgagor and such decree or
     order shall have remained in force and not dismissed for a period of 60
     days; or

          (e) the related Mortgagor shall consent to the appointment of a
     conservator or receiver or liquidator in any insolvency, readjustment of
     debt, marshaling of assets and liabilities or similar proceedings of or
     relating to such Mortgagor or of or relating to all or substantially all of
     its property; or

          (f) the related Mortgagor shall admit in writing its inability to pay
     its debts generally as they become due, file a petition to take advantage
     of any applicable insolvency or reorganization statute, make an assignment
     for the benefit of its creditors, or voluntarily suspend payment of its
     obligations; or

          (g) the Master Servicer shall have received notice of the commencement
     of foreclosure or similar proceedings with respect to the related Mortgaged
     Property;

provided, however, that a Serviced Mortgage Loan will cease to be a Specially
Serviced Mortgage Loan when a Liquidation Event has occurred with respect to
such Serviced Mortgage Loan, when the related Mortgaged Property has become an
REO Property or, so long as at such time no circumstance identified in clauses
(a) through (g) above exists that would cause such Serviced Mortgage Loan to
continue to be characterized as a Specially Serviced Mortgage Loan, when:


                                     -104-



          (w)  with respect to the circumstances described in clause (a) of this
               definition, the related Mortgagor has made three consecutive full
               and timely Monthly Payments under the terms of such Mortgage Loan
               (as such terms may be changed or modified in connection with a
               bankruptcy or similar proceeding involving the related Mortgagor
               or by reason of a modification, extension, waiver or amendment
               granted or agreed to by the Master Servicer or the Special
               Servicer pursuant to Section 3.20);

          (x)  with respect to the circumstances described in clause (b) of this
               definition, the default is cured in the good faith, reasonable
               judgment of the Special Servicer;

          (y)  with respect to the circumstances described in clauses (c), (d),
               (e) and (f) of this definition, such circumstances cease to exist
               in the good faith, reasonable judgment of the Special Servicer,
               but, with respect to any bankruptcy or insolvency proceedings
               described in clauses (d), (e) and (f), no later than the entry of
               an order or decree dismissing such proceeding;

          (z)  with respect to the circumstances described in clause (g) of this
               definition, such proceedings are terminated.

          The Special Servicer may conclusively rely on the Master Servicer's
determination as to whether a Servicing Transfer Event has occurred giving rise
to a Serviced Mortgage Loan's becoming a Specially Serviced Mortgage Loan.
Except as provided below in this sentence, if any Mortgage Loan that is part of
a Serviced Loan Combination becomes a Specially Serviced Mortgage Loan, then the
other Mortgage Loan or each of the other Mortgage Loans, as the case may be, in
such Loan Combination shall also become a Specially Serviced Mortgage Loan;
provided that if, subject to the terms, conditions and limitations of the
related Co-Lender Agreement, a Serviced Non-Trust Mortgage Loan Noteholder
prevents the occurrence of a Servicing Transfer Event with respect to the
related Serviced Combination Trust Mortgage Loan through the exercise of any
cure rights granted under the related Co-Lender Agreement with respect to such
Serviced Combination Trust Mortgage Loan, then the existence of such Servicing
Transfer Event with respect to the related Serviced Non-Trust Mortgage Loan
(because any such cure rights do not include the cure of defaults under the
related Serviced Non-Trust Mortgage Loan) will not, in and of itself, result in
any Mortgage Loan that is part of the subject Serviced Loan Combination becoming
a Specially Serviced Mortgage Loan (provided that a separate Servicing Transfer
Event may occur with respect thereto).

          None of the Outside Serviced Mortgage Loans shall constitute a
Specially Serviced Mortgage Loan hereunder.

Loan that is a Specially Serviced Mortgage Loan.

the Due Date specified in the related Mortgage Note (as in effect on the Closing
Date) on which the last payment of principal is due and payable under the terms
of such Mortgage Note (as in effect on the Closing Date), without regard to any
change in or modification of such terms in connection with a bankruptcy or
similar proceeding involving the related Mortgagor or a modification, extension,
waiver or amendment of such Mortgage Loan granted or agreed to by the Special
Servicer (or the Master Servicer, if applicable) pursuant to Section 3.20 (or,
in the case of an Outside Serviced Trust Mortgage Loan, by the applicable
Outside Servicer pursuant to the related Outside Servicing Agreement) and, in
the case of an ARD Mortgage Loan, without regard to its Anticipated Repayment
Date.

          "Stated Principal Balance" shall mean: (a) with respect to any Trust
Mortgage Loan (and any successor REO Trust Mortgage Loan with respect thereto),

the Principal Distribution Amount for such Distribution Date allocable to such
Trust Mortgage Loan (or any such successor REO Trust Mortgage Loan with respect
thereto), without giving effect to any adjustments pursuant to Section 1.03 in
connection with the calculation of the Adjusted Net Principal Distribution
Amount, and (ii) the principal portion of any Realized Loss incurred in respect
of such Trust Mortgage Loan (or any such successor REO Trust Mortgage Loan with
respect thereto) during the applicable related Collection Period (or, in the

Outside Servicing Agreement and/or the related Co-Lender Agreement for less than
the related Purchase Price or a Final Recovery Determination with respect to an
Outside Serviced Trust Mortgage Loan or any successor REO Trust Mortgage Loan
with respect thereto, during the related Underlying Collection Period) (provided
that, if some or all of the principal portion of such Realized Loss constitutes
an Advance that previously reduced the Stated Principal Balance of such Trust
Mortgage Loan by operation of clause (i) above, then the amount of that Advance
included in the principal portion of such Realized Loss shall not further reduce
the Stated Principal Balance of such Trust Mortgage Loan under this clause
(ii)); and (b) with respect to any Serviced Non-Trust Mortgage Loan (and any
successor REO Mortgage Loan with respect thereto), the Cut-off Date Balance of
such Non-Trust Mortgage Loan, as permanently reduced on each related Master
Servicer Remittance Date (to not less than zero) by (i) any principal amounts in
respect of such Non-Trust Mortgage Loan (or any such successor REO Mortgage Loan
with respect thereto) distributed to the related Non-Trust Mortgage Loan
Noteholder on such Master Servicer Remittance Date, and (ii) the principal
portion of any Realized Loss incurred in respect of such Non-Trust Mortgage Loan
(or any such successor REO Mortgage Loan with respect thereto) in connection
with a Liquidation Event or the forgiveness of principal during the related
Collection Period. Notwithstanding the foregoing, if a Liquidation Event occurs
in respect of any Mortgage Loan or any related REO Property, then the "Stated
Principal Balance" of such Mortgage Loan or of any successor REO Mortgage Loan
with respect thereto, as the case may be, shall be zero commencing as of the
first Distribution Date (or, in the case of a Serviced Non-Trust Mortgage Loan
or any successor REO Mortgage Loan with respect thereto, the first related
Master Servicer Remittance Date) following the end of the applicable Collection
Period in which such Liquidation Event occurred; provided that, in the case of
an Outside Serviced Trust Mortgage Loan or any successor REO Trust Mortgage Loan
with respect thereto, if the subject Liquidation Event is a Final Recovery
Determination made by the applicable Outside Servicer with respect to, or a
Permitted Purchase under the related Outside Servicing Agreement and/or the
related Co-Lender Agreement of,


                                     -106-



such Trust Mortgage Loan or REO Trust Mortgage Loan, as the case may be, then
references to "Collection Period" in this sentence shall be deemed to mean the

Regular Interests for the related Interest Accrual Period; and (g) with respect
to any other REMIC II Regular Interest for any Distribution Date, subject to
Section 4.05(d), an amount of interest equal to the amount of Uncertificated
Accrued Interest in respect of the subject REMIC II Regular Interest for the
related Interest Accrual Period, reduced (to not less than zero) by the product
of (i) any Net Aggregate Prepayment Interest Shortfall for such Distribution
Date (exclusive of any portion thereof allocable to the Group HAF REMIC II
Regular Interests and/or the Group SBC REMIC II Regular Interests), multiplied
by (ii) a fraction, the numerator of which is the amount of Uncertificated
Accrued Interest in respect of the subject REMIC II Regular Interest for the
related Interest Accrual Period, and the denominator of which is the aggregate
amount of Uncertificated Accrued Interest in respect of all the REMIC II Regular
Interests (other than the Group HAF REMIC II Regular Interests and the Group SBC
REMIC II Regular Interests) for the related Interest Accrual Period. For
purposes of this definition, the portion, if any, of the Net Aggregate
Prepayment Interest Shortfall for any Distribution Date that is allocable to any
Loan REMIC Regular Interest, REMIC I Regular Interest or REMIC II Regular
Interest will equal the amount, if any, by which the Uncertificated
Distributable Interest with respect to such Loan REMIC


                                      -118-



Regular Interest, REMIC I Regular Interest or REMIC II Regular Interest, as the
case may be, for such Distribution Date has been reduced as a result of such Net
Aggregate Prepayment Interest Shortfall.

          "Uncertificated Principal Balance" shall mean the principal balance of
any Loan REMIC Regular Interest, REMIC I Regular Interest or REMIC II Regular
Interest outstanding as of any date of determination. As of the Closing Date:
(a) the Uncertificated Principal Balance of each Loan REMIC Regular Interest (if
any) shall equal the Cut-off Date Balance of the corresponding Trust Mortgage
Loan; (b) the Uncertificated Principal Balance of each STML Group A REMIC I
Regular Interest and STML Group B REMIC I Regular Interest shall equal the
initial "Uncertificated Principal Balance" thereof set forth in the Preliminary
Statement; and (c) the Uncertificated Principal Balance of each other REMIC I
Regular Interest shall equal the Cut-off Date Balance of the corresponding Trust
Mortgage Loan. As of the Closing Date, the Uncertificated Principal Balance of
each REMIC II Regular Interest shall equal the amount set forth in the
Preliminary Statement hereto as its initial "Uncertificated Principal Balance."
On each Distribution Date, the Uncertificated Principal Balance of each REMIC II
Regular Interest shall be reduced by all distributions of principal deemed to
have been made thereon on such Distribution Date pursuant to Section 4.01(l),
and shall be further reduced (subject to Section 4.05) on such Distribution Date
by all Realized Losses and Additional Trust Fund Expenses deemed to have been
allocated thereto on such Distribution Date pursuant to Section 4.04(b). On each
Distribution Date, the Uncertificated Principal Balance of each REMIC I Regular
Interest shall be reduced by all distributions of principal deemed to have been
made in respect of such REMIC I Regular Interest on such Distribution Date
pursuant to Section 4.01(m), and shall be further reduced on such Distribution
Date by all Realized Losses and Additional Trust Fund Expenses deemed to have
been allocated thereto on such Distribution Date pursuant to Section 4.04(c). On
each Distribution Date, the Uncertificated Principal Balance of each Loan REMIC
Regular Interest (if any) shall be reduced by all distributions of principal
deemed to have been made in respect of such Loan REMIC Regular Interest on such
Distribution Date pursuant to Section 4.01(n), and shall be further reduced on
such Distribution Date by all Realized Losses and Additional Trust Fund Expenses
deemed to have been allocated thereto on such Distribution Date pursuant to
Section 4.04(d). Notwithstanding the foregoing, on any given Distribution Date,
the Uncertificated Principal Balance of any REMIC II Regular Interest shall be
subject to increase (and, when appropriate, shall be increased), as and to the
extent provided in Section 4.05(c).

          "Underlying Collection Period" shall mean, with respect to any Outside
Serviced Trust Mortgage Loan or any successor REO Trust Mortgage Loan with
respect thereto, the applicable "Collection Period" under the related Outside
Servicing Agreement or any other applicable period under the related Outside
Servicing Agreement that is comparable to a Collection Period hereunder.

          "Underwriters" shall mean Lehman Brothers and UBS Securities LLC and
their respective successors in interest.

          "United States Tax Person" shall mean a citizen or resident of the
United States, a corporation, partnership or other entity created or organized
in, or under the laws of, the United States or any state or the District of
Columbia, or an estate whose income from sources without the United States is
includible in gross income for United States federal income tax purposes
regardless of its connection with the conduct of a trade or business within the
United States, or a trust if a court within the United States is able to
exercise primary supervision over the administration of the trust and one or
more United States persons have the authority to control all substantial
decisions of the trust (or to the extent


                                      -119-



provided in the Treasury regulations, if the trust was in existence on August
20, 1996 and elected to be treated as a United States person), all within the
meaning of Section 7701(a) (30) of the Code.

          "United States Securities Person" shall mean any "U.S. person" as
defined in Rule 902(k) of Regulation S.

          "Voting Rights" shall mean the portion of the voting rights of all of
the Certificates which is allocated to any Certificate. At all times during the
term of this Agreement, 99% of the Voting Rights shall be allocated among the
Holders of the various Classes of the Principal Balance Certificates in
proportion to the respective Class Principal Balances of their Certificates, and
1% of the Voting Rights shall be allocated to the Holders of the Interest-Only
Certificates. Voting Rights allocated to a Class of Certificateholders shall be
allocated among such Certificateholders in standard proportion to the Percentage
Interests evidenced by their respective Certificates. No Voting Rights shall be
allocated to the Certificates that are not Regular Interest Certificates.
Notwithstanding the foregoing, solely for purposes of allocating Voting Rights
to the Loan-Specific Certificates, the Class Principal Balance of each Class of
Loan-Specific Certificates will be deemed reduced by its applicable share of any
Appraisal Reduction Amounts in respect of the related Split Trust Mortgage Loans
or any successor REO Trust Mortgage Loans with respect thereto. The aggregate of
(i) any Appraisal Reduction Amount in respect of the 70 Hudson Street Trust
Mortgage Loan or any successor REO Trust Mortgage Loan with respect thereto, up
to the amount of the outstanding Uncertificated Principal Balance of REMIC I
Regular Interest HUD-B, (ii) any Appraisal Reduction Amount in respect of the
AMLI of North Dallas Trust Mortgage Loan or any successor REO Trust Mortgage
Loan with respect thereto, up to the amount of the outstanding Uncertificated
Principal Balance of REMIC I Regular Interest AMLI-B, and (iii) any Appraisal
Reduction Amount in respect of the Fountains of Miramar Trust Mortgage Loan or
any successor REO Trust Mortgage Loan with respect thereto, up to the amount of
the outstanding Uncertificated Principal Balance of REMIC I Regular Interest
FOM-B, shall be allocated to the Class HAF-11, Class HAF-10, Class HAF-9, Class
HAF-8, Class HAF-7, Class HAF-6, Class HAF-5, Class HAF-4, Class HAF-3, Class
HAF-2 and Class HAF-1 Certificates, in that order, in each case up to the
related Class Principal Balance. Any Appraisal Reduction Amount in respect of
the Sturbridge Commons Trust Mortgage Loan or any successor REO Trust Mortgage
Loan with respect thereto, up to the amount of the outstanding Uncertificated
Principal Balance of REMIC I Regular Interest STUR-B, shall be allocated to the
Class SBC-15, Class SBC-14, Class SBC-13, Class SBC-12, Class SBC-11, Class
SBC-10, Class SBC-9, Class SBC-8, Class SBC-7, Class SBC-6, Class SBC-5, Class
SBC-4, Class SBC-3, Class SBC-2 and Class SBC-1 Certificates, in that order, in
each case up to the related Class Principal Balance.

          "Weighted Average REMIC I Remittance Rate" shall mean, with respect to
any Interest Accrual Period, the rate per annum equal to the weighted average,
expressed as a percentage and rounded to six decimal places, of the respective
REMIC I Remittance Rates in effect for the REMIC I Regular Interests (other than
the STML Group B REMIC I Regular Interests) for such Interest Accrual Period,
weighted on the basis of the respective Uncertificated Principal Balances of
such REMIC I Regular Interests outstanding immediately prior to the related
Distribution Date.

          "Workout Fee" shall mean the fee designated as such in, and payable to
the Special Servicer with respect to certain collections on each Corrected
Mortgage Loan pursuant to, Section 3.11(c).


                                      -120-



          "Workout Fee Rate" shall mean, with respect to each Corrected Mortgage
Loan as to which a Workout Fee is payable, 1.0%.

          "Yield Maintenance Charge" shall mean the amount paid or payable, as
the context requires, as the result of a Principal Prepayment on, or other early
collection of principal of, a Mortgage Loan, which amount is not otherwise due
thereon in respect of principal or interest and has been calculated (based on
scheduled payments of interest and/or principal on such Mortgage Loan) to
compensate the holder for reinvestment losses based on the value of an interest
rate index at or near the time of prepayment. Any other prepayment premiums,
penalties and fees not so calculated will not be considered "Yield Maintenance
Charges". In addition, any Excess Defeasance Deposit Proceeds will not be
considered "Yield Maintenance Charges". In the event that a Yield Maintenance
Charge shall become due for any particular Serviced Mortgage Loan, the Master
Servicer shall be required to follow the terms and provisions contained in the
applicable Mortgage Note, provided, however, that, in the event the particular
Mortgage Note shall not specify the U.S. Treasuries which shall be used in
determining the discount rate or the reinvestment yield to be applied in such
calculation, the Master Servicer shall be required to use those U.S. Treasuries
which shall generate the lowest discount rate or reinvestment yield for the
purposes thereof. Accordingly, if either no U.S. Treasury issue, or more than
one U.S. Treasury issue, shall coincide with the term over which the Yield
Maintenance Charge shall be calculated (which depending on the applicable
Mortgage Note is based on the remaining average life of the subject Serviced
Mortgage Loan or the actual term remaining through the related Stated Maturity
Date or Anticipated Repayment Date, as applicable), the Master Servicer shall
use the applicable U.S. Treasury whose reinvestment yield is the lowest, with
such yield being based on the bid price for such issue as published in The Wall
Street Journal on the date that is 14 days prior to the date that the Yield
Maintenance Charge shall become due and payable (or, if such bid price is not
published on that date, the next preceding date on which such bid price is so
published) and converted to a monthly compounded nominal yield. The monthly
compounded nominal yield ("MEY") is derived from the reinvestment yield or
discount rate and shall be defined as MEY = (12 X [{(1+ "BEY"/2) ^1/6}-1]) X
100, where BEY is defined as the U.S. Treasury Reinvestment Yield which is in
decimal form and not in percentage, and 1/6 is the exponential power to which a
portion of the equation is raised. For example, using a BEY of 5.50%, the MEY =
(12 X [{(1+ .055/2) ^ 0.16667}- 1]) X 100 where .055 is the decimal version of
the percentage 5.5% and 0.16667 is the decimal version of the exponential power.
The MEY in the above calculation is 5.44%.

          "Yield Maintenance Treasury Rate" shall mean, for purposes of
calculating a Discount Rate, the yield calculated by the Master Servicer by
linear interpolation of the yields, as such yields are reported in Federal
Reserve Statistical Release H.15-Selected Interest Rates (519), under the
heading U.S. Government Securities/Treasury Constant Maturities, with respect to
the maturity dates set forth thereunder, one longer and one shorter, most nearly
approximating the maturity date (or, in the case of an ARD Trust Mortgage Loan
or any successor REO Trust Mortgage Loan with respect thereto, the Anticipated
Repayment Date) of the relevant prepaid Trust Mortgage Loan or REO Trust
Mortgage Loan. If Federal Reserve Statistical Release H.15 is no longer
published or does not indicate the information set forth above, then the Master
Servicer shall select a comparable publication or source for the purposes of
determining the Yield Maintenance Treasury Rate.

          "YM Principal Balance Certificates" shall mean, collectively, the
Class A-1, Class A-2, Class A-3, Class A-AB, Class A-4, Class A-1A, Class A-M,
Class A-J, Class B, Class C, Class D, Class E, Class F, Class G, Class H, Class
J and Class K Certificates.

     well as the singular, and the use of any gender herein shall be deemed to
     include the other gender;

               (ii) accounting terms not otherwise defined herein have the
     meanings assigned to them in accordance with GAAP;

               (iii) references herein to "Articles", "Sections", "Subsections",
     "Paragraphs" and other subdivisions without reference to a document are to
     designated Articles, Sections, Subsections, Paragraphs and other
     subdivisions of this Agreement;

               (iv) a reference to a Subsection without further reference to a
     Section is a reference to such Subsection as contained in the same Section
     in which the reference appears, and this rule shall also apply to
     Paragraphs and other subdivisions;

               (v) the words "herein", "hereof", "hereunder", "hereto", "hereby"
     and other words of similar import refer to this Agreement as a whole and
     not to any particular provision; and

               (vi) the terms "include" or "including" shall mean without

          SECTION 1.03. Certain Adjustments to the Principal Distributions on
the Certificates.

          (a) If any party hereto is reimbursed out of general collections on
the Mortgage Pool on deposit in the Pool Custodial Account for any unreimbursed
Advance that has been or is determined to be a Nonrecoverable Advance (together
with interest accrued and payable thereon pursuant to Section 3.11(g) or Section
4.03(d), as applicable, to the extent such interest was paid hereunder from a
source other than related Default Charges or Loss of Value Payments), then (for
purposes of calculating distributions on the Certificates), subject to Section
1.03(e), each such reimbursement and payment of interest shall be deemed to have
been made:

               first, out of any amounts then on deposit in the Pool Custodial
     Account that represent payments or other collections of principal Received
     by the Trust with respect to the Trust Mortgage Loans and/or REO Trust
     Mortgage Loans in the Loan Group that includes the Trust Mortgage Loan or
     REO Trust Mortgage Loan in respect of which such Nonrecoverable Advance was
     made, and which amounts, but for their application to reimburse such
     Nonrecoverable Advance (and/or to pay interest thereon), would be included
     in the Available Distribution Amount for the related Distribution Date;

               second, out of any amounts then on deposit in the Pool Custodial
     Account that represent payments or other collections of principal Received
     by the Trust with respect to the Trust Mortgage Loans or REO Trust Mortgage
     Loans in the Loan Group that does not include


                                      -122-



     the Trust Mortgage Loan or REO Trust Mortgage Loan in respect of which such
     Nonrecoverable Advance was made, and which amounts, but for their
     application to reimburse such Nonrecoverable Advance (and/or to pay
     interest thereon), would be included in the Available Distribution Amount
     for the related Distribution Date;

               third, out of any amounts then on deposit in the Pool Custodial
     Account that represent any other payments and/or collections Received by
     the Trust with respect to the Trust Mortgage Loans or REO Trust Mortgage
     Loans in the Loan Group that includes the Trust Mortgage Loan or REO Trust
     Mortgage Loan in respect of which such Nonrecoverable Advance was made, and
     which amounts, but for their application to reimburse such Nonrecoverable
     Advance (and/or to pay interest thereon), would be included in the
     Available Distribution Amount for the related Distribution Date;

               fourth, out of any amounts then on deposit in the Pool Custodial
     Account that represent any other payments and/or collections Received by
     the Trust with respect to the Trust Mortgage Loans or REO Trust Mortgage
     Loans in the Loan Group that does not include the Trust Mortgage Loan or
     REO Trust Mortgage Loan in respect of which such Nonrecoverable Advance was
     made, and which amounts, but for their application to reimburse such
     Nonrecoverable Advance (and/or to pay interest thereon), would be included
     in the Available Distribution Amount for the related Distribution Date; and

               fifth, out of any other amounts then on deposit in the Pool
     Custodial Account that may be available to reimburse the subject
     Nonrecoverable Advance and/or to pay interest thereon.

          (b) If and to the extent that any payment or other collection of
principal of any Trust Mortgage Loan or REO Trust Mortgage Loan is deemed to be
applied in accordance with Section 1.03(a) to reimburse a Nonrecoverable Advance
or to pay interest thereon, and further if and to the extent that such payment
or other collection of principal constitutes part of the Net Principal
Distribution Amount for any Distribution Date, then: (i) the Adjusted Net
Principal Distribution Amount for such Distribution Date shall exclude such
payment or other collection of principal; and (ii) in accordance with clause (c)
of the definition of "Adjusted Net Principal Distribution Amount", in order to
calculate the Adjusted Net Principal Distribution Amount for such Distribution
Date, the amount of such payment or other collection of principal shall be
subtracted from the Net Principal Distribution Amount for such Distribution
Date. In addition, for purposes of determining the respective portions of the
Adjusted Net Principal Distribution Amount for any Distribution Date that are
attributable to the two Loan Groups, the Trustee shall take into account whether
any payment or other collection of principal excluded from such Adjusted Net
Principal Distribution Amount in accordance with the preceding sentence relates
to a Trust Mortgage Loan or REO Trust Mortgage Loan, as the case may be, in Loan
Group No. 1 or Loan Group No. 2.

          (c) If and to the extent that (1) any Advance is determined to be a
Nonrecoverable Advance, (2) such Advance is reimbursed or interest thereon is
paid out of general principal collections on the Mortgage Pool as contemplated
by Section 1.03(a) above and (3) the particular item for which such Advance was
originally made or such interest on such Advance, as the case may be, is
subsequently Received by the Trust (in whole or in part) out of payments or
other collections in respect of the related Trust Mortgage Loan or REO Trust
Mortgage Loan (such item or such interest on such


                                      -123-



Advance, as the case may be, if and to the extent so collected, a "Recovered
Amount"), then: (i) without duplication of any amounts already included therein,
the Adjusted Net Principal Distribution Amount for the Distribution Date that
corresponds to the related Collection Period in which such item or such interest
on such Advance, as the case may be, was Received by the Trust shall include
such Recovered Amount; (ii) in accordance with clause (b) of the definition of
"Adjusted Net Principal Distribution Amount", in order to calculate the Adjusted
Net Principal Distribution Amount for the Distribution Date that corresponds to
the related Collection Period in which such item was Received by the Trust, such
Recovered Amount (to the extent not already included therein) shall be added to
the Net Principal Distribution Amount for such Distribution Date; and (iii) such
Advance or such interest thereon, as the case may be, to the extent of such
Recovered Amount, will no longer be considered to have been reimbursed or paid,
as the case may be, out of general principal collections on the Mortgage Pool.
In addition, if and to the extent that any Advance is determined to be a
Nonrecoverable Advance, interest on such Advance is paid out of general
principal collections on the Mortgage Pool as contemplated by Section 1.03(a)
above and such interest on such Advance is subsequently reimbursed to the Trust
out of Default Charges or Loss of Value Payments collected on the Trust Mortgage
Loan or REO Trust Mortgage Loan as to which such Advance was made, then: (i) the
Adjusted Net Principal Distribution Amount for the Distribution Date that
corresponds to the related Collection Period in which such Default Charges were
Received by the Trust or such Loss of Value Payments were so applied shall
include the portion of such Default Charges or Loss of Value Payments that was
applied to reimburse the Trust for such interest on such Advance; (ii) in
accordance with clause (b) of the definition of "Adjusted Net Principal
Distribution Amount", in order to calculate the Adjusted Net Principal
Distribution Amount for the Distribution Date that corresponds to the related
Collection Period in which such Default Charges were Received by the Trust or
such Loss of Value Payments were so applied, an amount equal to the portion of
such Default Charges or Loss of Value Payments that was applied to reimburse the
Trust for such interest on such Advance shall be added to the Net Principal
Distribution Amount for such Distribution Date; and (iii) such interest on such
Advance, to the extent that the Trust was reimbursed for such interest out of
such Default Charges or such Loss of Value Payments, will no longer be
considered to have been paid out of general principal collections on the
Mortgage Pool. In addition, for purposes of determining the respective portions
of the Adjusted Net Principal Distribution Amount for any Distribution Date that
are attributable to the two Loan Groups, the Trustee shall take into account
whether any Recovered Amount, Default Charges or Loss of Value Payments included
in such Adjusted Principal Distribution Amount in accordance with the foregoing
sentences of this Section 1.03(c) relates to a Trust Mortgage Loan or REO Trust
Mortgage Loan, as the case may be, in Loan Group No. 1 or Loan Group No. 2;
provided that, if the Nonrecoverable Advance or interest thereon to which such
Recovered Amount, Default Charges or Loss of Value Payments, as the case may be,
corresponds was deemed reimbursed or paid, as the case may be, out of payments
and other collections of principal attributable to both Loan Groups, then such
Recovered Amount, Default Charges or Loss of Value Payments, as the case may be,
shall be deemed allocated to the two Loan Groups, in each case up to the amount
of payments and other collections of principal attributable thereto that were
deemed applied to reimburse or pay, as the case may be, such Nonrecoverable
Advance or interest thereon, in the reverse order contemplated by Section
1.03(a).

          (d) Nothing contained in this Section 1.03 is intended to limit the
ability of any party hereto that is entitled to reimbursement hereunder for any
unreimbursed Advances that have been or are determined to be Nonrecoverable
Advances (together with interest accrued and payable thereon pursuant to Section
3.11(g) or Section 4.03(d)) to be reimbursed from collections of principal
Received by the


                                      -124-



Trust with respect to the Mortgage Pool. Instead the order of priority set forth
in Section 1.03(a) is a deemed allocation only for purposes of calculating
distributions on the Certificates.

          (e) Notwithstanding anything to the contrary contained herein, no
collections on any particular HAF Split Trust Mortgage Loan or related REO
Property that are otherwise distributable with respect to the Class HAF
Certificates on any Distribution Date may be applied to reimburse any Advance or
portion thereof with respect to, or to pay any Additional Trust Fund Expense or
portion thereof that is related or allocable to, any other Mortgage Loan or REO
Property (including another Split Trust Mortgage Loan or any related REO
Property). Further notwithstanding anything to the contrary contained herein, no
amounts otherwise distributable with respect to the Class SBC Certificates on
any Distribution Date may be applied to reimburse any Advance or portion thereof
with respect to, or to pay any Additional Trust Fund Expense or portion thereof
that is related or allocable to, any Mortgage Loan or REO Property other than
the Sturbridge Commons Trust Mortgage Loan or any related REO Property.
Collections on any particular Split Trust Mortgage Loan or related REO Property
may only be applied to the reimbursement of Advances with respect to, or the
payment of Additional Trust Fund Expenses or the respective portions thereof
that are related or allocable to, such Split Trust Mortgage Loan or REO
Property.

                                   ARTICLE II

       CONVEYANCE OF TRUST MORTGAGE LOANS; REPRESENTATIONS AND WARRANTIES;
                       ORIGINAL ISSUANCE OF CERTIFICATES

          SECTION 2.01.  Creation of Trust; Conveyance of Trust Mortgage Loans.

          (a) It is the intention of the parties hereto that a common law trust
be established pursuant to this Agreement and the laws of the State of New York
and that such trust be designated as "LB-UBS Commercial Mortgage Trust 2006-C4".
LaSalle Bank National Association is hereby appointed, and does hereby agree, to
act as Trustee hereunder and, in such capacity, to hold the Trust Fund in trust
for the exclusive use and benefit of all present and future Certificateholders.

          The Depositor, concurrently with the execution and delivery hereof,
does hereby assign, sell, transfer, set over and otherwise convey to the Trustee
in trust, without recourse, for the benefit of the Certificateholders, all the
right, title and interest of the Depositor in, to and under (i) the Trust
Mortgage Loans, (ii) the UBS/Depositor Mortgage Loan Purchase Agreement, (iii)
the respective Co-Lender Agreements; and (iv) all other assets included or to be
included in the Trust Fund. Such assignment includes all interest and principal
received or receivable on or with respect to the Trust Mortgage Loans and due
after the Cut-off Date and, in the case of each Trust Mortgage Loan that is part
of a Loan Combination, is subject to the provisions of the related Co-Lender
Agreement. With respect to each Trust Mortgage Loan that is part of a Loan
Combination, the Trustee, on behalf of the Trust, assumes the obligations of the
holder of such Trust Mortgage Loan and the related Mortgage Note under, and
agrees to be bound by, the related Co-Lender Agreement.

          The parties hereto acknowledge and agree that, notwithstanding Section
11.07, the transfer of the Trust Mortgage Loans and the related rights and
property accomplished hereby is absolute and is intended by them to constitute a
sale.

          The Trust Fund shall constitute the sole assets of the Trust. Except
as expressly provided herein, the Trust may not issue or invest in additional
securities, borrow money or make loans to other Persons. The fiscal year end of
the Trust shall be December 31.

          (b) In connection with the Depositor's assignment pursuant to Section
2.01(a) above, the Depositor shall, in the case of each Lehman Trust Mortgage
Loan, deliver to and deposit with, and the UBS Mortgage Loan Seller has
(pursuant to the UBS/Depositor Mortgage Loan Purchase Agreement) agreed, in the
case of each UBS Trust Mortgage Loan, to deliver to and deposit with, on or
before the Closing Date: (i) the Trustee or a Custodian appointed thereby, the
Mortgage File for such Trust Mortgage Loan, with copies of each Mortgage File to
be delivered by the Trustee to, upon request, the Master Servicer (and at the
expense of the Trustee and not at the expense of the Trust Fund), within 10
Business Days of such request; and (ii) the Master Servicer (or, at the
direction of the Master Servicer, to the appropriate Sub-Servicer), all
unapplied Escrow Payments and Reserve Funds in the possession or under the
control of the Depositor or the UBS Mortgage Loan Seller, as the case may be,
that relate to such Trust Mortgage Loan (except in the case of an Outside
Serviced Trust Mortgage Loan). None of the Trustee, any Custodian, the Master
Servicer or the Special Servicer shall be liable for any failure by a Mortgage
Loan Seller or the Depositor to comply with the document delivery requirements
of the respective Mortgage Loan Purchase Agreements and this Section 2.01(b). In


                                     -126-



addition, the UBS Mortgage Loan Seller shall be required, pursuant to the
UBS/Depositor Mortgage Loan Purchase Agreement, in the case of each Outside
Serviced Trust Mortgage Loan, to deliver to and deposit with the Master
Servicer, within 45 days of the Closing Date, a copy of the mortgage file that
was delivered to the related Outside Trustee under the related Non Trust
Mortgage Loan Securitization Agreement.

          After the Depositor's transfer of the Trust Mortgage Loans to the
Trustee pursuant to Section 2.01(a), the Depositor shall not take any action
inconsistent with the Trust's ownership of the Trust Mortgage Loans.

          (c) The Depositor hereby covenants that it shall retain with respect
to each Lehman Trust Mortgage Loan (other than an Outside Serviced Trust
Mortgage Loan), and the UBS Mortgage Loan Seller has covenanted in the
UBS/Depositor Mortgage Loan Purchase Agreement that it shall retain with respect
to each UBS Trust Mortgage Loan (other than an Outside Serviced Trust Mortgage
Loan), an Independent Person (each such Person, a "Recording Agent") through
which the Depositor or the UBS Mortgage Loan Seller, as applicable, shall: (i)
promptly (and in any event within 45 days following the later of the Closing
Date and the date on which all necessary recording information is available to
the subject Recording Agent) submit for recording in the appropriate public
office for real property records each related assignment of Mortgage and
assignment of Assignment of Leases in favor of, and delivered under clause
(a)(iv) of the definition of "Mortgage File" to, the Trustee; and (ii) cause
each such assignment of Mortgage and assignment of Assignment of Leases to be
delivered to the Trustee following its return by the appropriate public office
for real property records, with copies of any such returned assignments to be
delivered by the Trustee to the Master Servicer, at the expense of the Depositor
(in the case of Lehman Trust Mortgage Loans) or the UBS Mortgage Loan Seller (in
the case of UBS Trust Mortgage Loans), as applicable, at least every 90 days
after the Closing Date (or at such additional times upon the request of the
Master Servicer if reasonably necessary for the ongoing administration and/or
servicing of the related Serviced Trust Mortgage Loan by the Master Servicer);
provided that, in those instances where the public recording office retains the
original assignment of Mortgage or assignment of Assignment of Leases, the
Trustee shall obtain a certified copy of the recorded original.

          Notwithstanding the foregoing, the Depositor may, in the case of a
Lehman Trust Mortgage Loan (other than an Outside Serviced Trust Mortgage Loan),
and the UBS Mortgage Loan Seller may, in the case of a UBS Trust Mortgage Loan
(other than an Outside Serviced Trust Mortgage Loan), request the Trustee to
submit for recording any of the assignments of Mortgage and/or assignments of
Assignment of Leases referred to in the prior paragraph, and in such event, the
requesting party shall cause any such unrecorded or unfiled document to be
delivered to the Trustee. The Trustee shall promptly undertake to submit for
recording or filing any such document upon its receipt thereof.

          Each assignment of Mortgage and assignment of Assignment of Leases
referred to in the prior two paragraphs that is submitted for recording shall
reflect that it should be returned by the public recording office to the Trustee
or its agent following recording; provided that, in those instances where the
public recording office retains the original assignment of Mortgage or
assignment of Assignment of Leases, the Trustee shall obtain therefrom a
certified copy of the recorded original. At least every 90 days after the
Closing Date (or at additional times upon the request of the Master Servicer if
reasonably necessary for the ongoing administration and/or servicing of the
related Trust Mortgage Loan by the


                                     -127-



Master Servicer) and at the expense of the Depositor (in the case of a Lehman
Trust Mortgage Loan (other than an Outside Serviced Trust Mortgage Loan)) or the
UBS Mortgage Loan Seller (in the case of a UBS Trust Mortgage Loan (other than
an Outside Serviced Trust Mortgage Loan)), the Trustee shall forward to the
Master Servicer a copy of any of the aforementioned assignments of Mortgage
and/or assignments of Assignment of Leases that have been received by the
Trustee.

          The Depositor shall bear the out-of-pocket costs and expenses of the
recording referred to in the first two paragraphs of this Section 2.01(c) with
respect to the Lehman Trust Mortgage Loans (other than the Outside Serviced
Trust Mortgage Loans), and the UBS/Depositor Mortgage Loan Purchase Agreement
provides that the UBS Mortgage Loan Seller shall bear the out-of-pocket costs
and expenses of the recording referred to in the first two paragraphs of this
Section 2.01(c) with respect to the UBS Trust Mortgage Loans (other than the
Outside Serviced Trust Mortgage Loans).

          If any of the assignments of Mortgage and/or assignments of Assignment
of Leases referred to in the first two paragraphs of this Section 2.01(c)
relating to a UBS Trust Mortgage Loan (other than an Outside Serviced Trust
Mortgage Loan) is lost or returned unrecorded because of a defect therein, then
the Trustee shall direct the UBS Mortgage Loan Seller (pursuant to the
UBS/Depositor Mortgage Loan Purchase Agreement) promptly to prepare or cause the
preparation of a substitute therefor or to cure such defect, as the case may be,
and to deliver to the Trustee the substitute or corrected document. If any of
the assignments of Mortgage and/or assignments of Assignment of Leases referred
to in the first two paragraphs of this Section 2.01(c) relating to a Lehman
Trust Mortgage Loan (other than an Outside Serviced Trust Mortgage Loan) is lost
or returned unrecorded because of a defect therein, then the Depositor shall
promptly prepare or cause the preparation of a substitute therefor or cure such
defect, as the case may be, and shall deliver to the Trustee the substitute or
corrected document. The Trustee shall upon receipt, whether from the UBS
Mortgage Loan Seller or the Depositor, cause the same to be duly recorded.

          In addition to the foregoing, the Trustee shall retain an Independent
Person (such Person, the "Filing Agent"), at the expense of American Capital
Strategies Ltd. (the "Payee"), pursuant to a letter agreement dated the Closing
Date (the "Filing Letter Agreement") between the Payee, the Depositor, the UBS
Mortgage Loan Seller and the Trustee, and the Trustee shall, with respect to
each Trust Mortgage Loan, through the Filing Agent: (i) promptly (and in any
event within 45 days following the later of the Closing Date and the date on
which all necessary filing information is available to such Filing Agent) file
in the appropriate public office for UCC Financing Statements, each related
assignment of UCC Financing Statement prepared by or on behalf of the Depositor
(with respect to each Lehman Trust Mortgage Loan) or by or on behalf of the UBS
Mortgage Loan Seller (with respect to each UBS Trust Mortgage Loan), in favor
of, and delivered pursuant to clause (a)(xiv) of the definition of "Mortgage
File" to, the Trustee; and (ii) cause each such assignment of UCC Financing
Statement to be delivered to the Trustee following its return by the appropriate
public filing office for UCC Financing Statements, with copies of any such
returned assignments to be delivered by the Trustee to the Master Servicer, at
the expense of the Depositor (in the case of Lehman Trust Mortgage Loans) or the
UBS Mortgage Loan Seller (in the case of UBS Trust Mortgage Loans), as
applicable, at least every 90 days after the Closing Date (or at such additional
times upon the request of the Master Servicer if reasonably necessary for the
ongoing administration and/or servicing of the related Trust Mortgage Loan by
the Master Servicer). Each assignment of UCC Financing Statement referred to in
the prior sentence that is filed by or on behalf of the Trustee shall reflect
that the file copy thereof should be returned to the Trustee or its agent
following filing. The Depositor (with respect to the Lehman Trust Mortgage
Loans) hereby agrees, and


                                     -128-



the UBS Mortgage Loan Seller (with respect to the UBS Trust Mortgage Loans) has
agreed pursuant to the UBS/Depositor Mortgage Loan Purchase Agreement, to
reasonably cooperate with the Trustee (and the Filing Agent) with respect to the
filing of the assignments of UCC Financing Statements as described in this
paragraph and to forward to the Trustee filing confirmation, if any, received by
such party in connection with assignments of UCC Financing Statements filed in
accordance with this paragraph.

          Notwithstanding the foregoing, to the extent the Trustee provides the
Payee, pursuant to the Filing Letter Agreement, with an invoice for the expenses
(i) reasonably to be incurred in connection with the filings referred to in the
preceding paragraph and (ii) required to be paid by the Payee pursuant to the
Filing Letter Agreement, and such expenses are not paid by the Payee in advance
of such filings, the Trustee, at the expense of the Depositor (with respect to
each Lehman Trust Mortgage Loan) and the UBS Mortgage Loan Seller (with respect
to each UBS Trust Mortgage Loan), shall only be required to cause the Filing
Agent to file the assignments of UCC Financing Statements with respect to Trust
Mortgage Loans secured by hotel or hospitality properties.

          (d) In connection with the Depositor's assignment pursuant to Section
2.01(a) above, the Depositor shall, in the case of each Lehman Trust Mortgage
Loan (other than an Outside Serviced Trust Mortgage Loan), deliver to and
deposit with, and the UBS Mortgage Loan Seller has agreed (pursuant to the
UBS/Depositor Mortgage Loan Purchase Agreement), in the case of each UBS Trust
Mortgage Loan (other than an Outside Serviced Trust Mortgage Loan), to deliver
to and deposit with, the Master Servicer (or, at the direction of the Master
Servicer, to and with the applicable Sub-Servicer), within 45 days of the
Closing Date, the Mortgage Loan Origination Documents that relate to such
Serviced Trust Mortgage Loan; provided that neither the Depositor nor the UBS
Mortgage Loan Seller shall be required to deliver any draft documents,
privileged or other communications or correspondence, credit underwriting or due
diligence analyses or information, credit committee briefs or memoranda or other
internal approval documents or data or internal worksheets, memoranda,
communications or evaluations.

          The Master Servicer shall review the documents with respect to each
Serviced Trust Mortgage Loan delivered by the Depositor or the UBS Mortgage Loan
Seller pursuant to or as contemplated by the immediately preceding paragraph and
provide to the Depositor or the UBS Mortgage Loan Seller, as applicable, with a
copy to the Controlling Class Representative and the Special Servicer, a
certificate in the form of Exhibit V attached hereto (the "Master Servicer
Certification") within 90 days of the Closing Date acknowledging its (or, if the
Master Servicer has directed that such documents be delivered only to the
applicable Sub-Servicer, the applicable Sub-Servicer's) receipt as of the date
of the Master Servicer Certification of such documents actually received;
provided that such review shall be limited to identifying the document received,
the Serviced Trust Mortgage Loan to which it purports to relate, that it appears
regular on its face and that it appears to have been executed (where
appropriate). Notwithstanding anything to the contrary set forth herein, to the
extent the Depositor or the UBS Mortgage Loan Seller, as applicable, has not
been notified in writing of its failure to deliver any document with respect to
a Serviced Trust Mortgage Loan required to be delivered pursuant to or as
contemplated by the immediately preceding paragraph prior to the date occurring
18 months following the date of the Master Servicer Certification, the Depositor
or the UBS Mortgage Loan Seller, as applicable, shall have no obligation to
provide such document.


                                     -129-



          In addition, pursuant to the related Mortgage Loan Purchase Agreement,
each Mortgage Loan Seller will be required to deliver, on the Closing Date, to
the Master Servicer for deposit in the Pool Custodial Account, the Initial
Deposit relating to each Initial Deposit Mortgage Loan, if any, being sold by
such Mortgage Loan Seller.

          The Master Servicer shall hold all funds, documents and records
received by it in accordance with this Section 2.01(d) (as well as any funds
received by it pursuant to Section 2.01(b)) on behalf of the Trustee in trust
for the benefit of the Certificateholders (and, insofar as they also relate to
any Serviced Non-Trust Mortgage Loan, on behalf of and for the benefit of the
related Serviced Non-Trust Mortgage Loan Noteholder).

          (e) In connection with the obligations of the Master Servicer under
Sections 3.01(e) and 3.19(c), with regard to each Serviced Trust Mortgage Loan
that is secured by the interests of the related Mortgagor in a hospitality
property and each Serviced Trust Mortgage Loan that has a related letter of
credit, the Depositor (with respect to each such Serviced Trust Mortgage Loan
that is a Lehman Trust Mortgage Loan) shall, and the UBS Mortgage Loan Seller
(with respect to each such Serviced Trust Mortgage Loan that is a UBS Trust
Mortgage Loan) will be obligated under the UBS/Depositor Mortgage Loan Purchase
Agreement to, deliver to and deposit with the Master Servicer, on or before the
Closing Date, any related franchise agreement and franchise comfort letter and
the original of such letter of credit.

          (f) It is not intended that this Agreement create a partnership or a
joint-stock association.

          SECTION 2.02.  Acceptance of Trust Fund by Trustee.

          (a) The Trustee, by its execution and delivery of this Agreement,
hereby accepts receipt, directly or through a Custodian on its behalf, of (i)
the Trust Mortgage Loans and all documents delivered to it that constitute
portions of the related Mortgage Files and (ii) all other assets delivered to it
and included in the Trust Fund, in good faith and without notice of any adverse
claim, and declares that it or a Custodian on its behalf holds and will hold
such documents and any other documents subsequently received by it that
constitute portions of the Mortgage Files, and that it holds and will hold the
Trust Mortgage Loans and such other assets, together with any other assets
subsequently delivered to it that are to be included in the Trust Fund, in trust
for the exclusive use and benefit of all present and future Certificateholders.
To the extent that the Mortgage File for any Serviced Combination Trust Mortgage
Loan relates to a Serviced Non-Trust Mortgage Loan, the Trustee shall also hold
such Mortgage File in trust for the use and benefit of the related Serviced
Non-Trust Mortgage Loan Noteholder. In connection with the foregoing, the
Trustee hereby certifies to each of the other parties hereto, each Mortgage Loan
Seller and each Underwriter that, as to each Trust Mortgage Loan, (i) the
Specially Designated Mortgage Loan Documents are in its possession or the
possession of a Custodian on its behalf, and (ii) the original Mortgage Note
(or, if accompanied by a lost note affidavit, the copy of such Mortgage Note)
received by it or any Custodian with respect to such Trust Mortgage Loan has
been reviewed by it or by such Custodian on its behalf and (A) appears regular
on its face (handwritten additions, changes or corrections shall not constitute
irregularities if initialed by the Mortgagor), (B) appears to have been executed
(where appropriate) and (C) purports to relate to such Trust Mortgage Loan.


                                     -130-



          (b) The Trustee or a Custodian on its behalf shall review the
documents delivered to it or such Custodian with respect to each Mortgage Loan
(such review to be conducted with respect to each document so delivered, prior
to the date that a certification or deemed certification, as applicable, is
required to be delivered in accordance with the following sentence), and the
Trustee shall, or shall cause a Custodian on its behalf to, subject to Sections
2.01, 2.02(c) and 2.02(d), certify (at the times and in the manner set forth
below) to each of the other parties hereto, each Mortgage Loan Seller and each
Underwriter and, in the case of a Serviced Non-Trust Mortgage Loan, to the
related Serviced Non-Trust Mortgage Loan Noteholder(s), that, as to each
Mortgage Loan then subject to this Agreement (except as specifically identified
in any exception report annexed to such certification or delivered with a deemed
certification, as applicable): (A) all documents specified in clauses (a)(i)
through (a)(viii) and (a)(xiv) (without regard to the second parenthetical in
such clause (a)(xiv)) of the definition of "Mortgage File" or, in the case of an
Outside Serviced Trust Mortgage Loan, in clauses (b)(i) through (b)(iii) of the
definition of "Mortgage File", are in its possession or the possession of a
Custodian on its behalf; (B) the recordation/filing contemplated by Section
2.01(c) (except in the case of an Outside Serviced Trust Mortgage Loan) has been
completed (based solely on receipt by the Trustee or by a Custodian on its
behalf of the particular recorded/filed documents); (C) all documents received
by it or any Custodian with respect to such Mortgage Loan have been reviewed by
it or by such Custodian on its behalf and (1) appear regular on their face
(handwritten additions, changes or corrections shall not constitute
irregularities if initialed by the Mortgagor), (2) appear to have been executed
(where appropriate) and (3) purport to relate to such Mortgage Loan; and (D)
based on the examinations referred to in Section 2.02(a) above and this Section
2.02(b) and only as to the foregoing documents, the information set forth in the
Trust Mortgage Loan Schedule with respect to the items specified in clauses (v)
and (vi)(B) of the definition of "Trust Mortgage Loan Schedule" accurately
reflects the information set forth in the Mortgage File. The certification
referred to in the first sentence of this Section 2.02(b) shall be delivered by
the Trustee in writing: (i) whether or not any exceptions are noted,
substantially in the form of Exhibit C hereto (with an exception report annexed
thereto), on or about the 60th day following the Closing Date; and (ii) if any
exceptions are noted, substantially in the form of Exhibit C hereto (with an
exception report annexed thereto), upon the earliest to occur of (X) the second
anniversary of the Closing Date, (Y) the day on which all material exceptions
have been removed and (Z) the day on which the Depositor has repurchased the
last affected Trust Mortgage Loan); and (iii) if any exceptions are noted
following the initial certification in clause (i) of this sentence, in the form
of an updated exception report, on or about the 90th day following the Closing
Date and monthly thereafter until the final certification in clause (ii) of this
sentence is delivered (and upon and by delivery of each such updated exception
report the Trustee shall be deemed to have made the certifications set forth in
clauses (A) through (D) of the first sentence of this Section 2.02(b) as to each
Mortgage Loan then subject to this Agreement, except as specifically identified
in such updated exception report). If the Trustee's obligation to deliver the
certifications contemplated in this subsection terminates because two years have
elapsed since the Closing Date, the Trustee shall (or shall cause a Custodian on
its behalf to) deliver a comparable certification, upon request, to any party
hereto, any Serviced Non-Trust Mortgage Loan Noteholder and/or any Underwriter.

          (c) None of the Trustee, the Master Servicer, the Special Servicer or
any Custodian is under any duty or obligation to inspect, review or examine any
of the documents, instruments, certificates or other papers relating to the
Mortgage Loans delivered to it to determine that the same are valid, legal,
effective, genuine, binding, enforceable, sufficient or appropriate for the
represented purpose or that they are other than what they purport to be on their
face. Furthermore, none of the Trustee, the Master Servicer, the Special
Servicer or any Custodian shall have any responsibility for


                                     -131-



determining whether the text of any assignment or endorsement is in proper or
recordable form, whether the requisite recording of any document is in
accordance with the requirements of any applicable jurisdiction, or whether a
blanket assignment is permitted in any applicable jurisdiction.

          (d) It is understood that the scope of the Trustee's review of the
Mortgage Files is limited solely to confirming that the documents specified in
clauses (a)(i) through (a)(viii) and (a)(xiv) (or, in the case of an Outside
Serviced Trust Mortgage Loan, in clauses (b)(i) through (b)(iii)) of the
definition of "Mortgage File" have been received and such additional information
as will be necessary for delivering the certifications required by Sections
2.02(a) and (b) above.

          (e) The Trustee, directly or through a Custodian retained by it,
shall: (i) provide for the safekeeping and preservation of the Mortgage Files
with respect to the Trust Mortgage Loans; (ii) segregate such Mortgage Files
from its own assets and the assets retained by it for others; (iii) maintain
such Mortgage Files in secure and fire resistant facilities in compliance with
customary industry standards; (iv) maintain disaster recovery protocols to
ensure the preservation of such Mortgage Files in the event of force majeure;
and (v) track and monitor the receipt and movement internally and externally of
such Mortgage Files and any release and reinstatement thereof.

          SECTION 2.03.  Repurchase of Trust Mortgage Loans for Document Defects
                         and Breaches of Representations and Warranties.

          (a) If any party hereto (other than the Depositor) discovers or
receives written notice, with respect to any Trust Mortgage Loan, that (i) any
document (A) constituting a part of the related Mortgage File pursuant to
clauses (a)(i) through (a)(xiii) (or, in the case of an Outside Serviced Trust
Mortgage Loan, clause (b)(i)) of the definition of "Mortgage File", (B)
specifically set forth on Schedule IX hereto with respect to a Lehman Trust
Mortgage Loan only or (C) specifically set forth on Exhibit D to the
UBS/Depositor Mortgage Loan Purchase Agreement with respect to any UBS Trust
Mortgage Loan only, in each such case, has not been executed (if applicable) or
is missing (each, a "Document Defect") or (ii) there exists a breach of any
representation or warranty of the UBS Mortgage Loan Seller made pursuant to
Section 3(b) of the UBS/Depositor Mortgage Loan Purchase Agreement with respect
to any UBS Trust Mortgage Loan (a "Breach") or a breach of any representation or
warranty of the Depositor made pursuant to Section 2.04(b) hereof with respect
to any Lehman Trust Mortgage Loan (also, a "Breach"), then such party shall give
prompt written notice thereof to each Rating Agency, the related Mortgage Loan
Seller, the other parties hereto and the Controlling Class Representative. If
the Depositor (in the case of a Lehman Trust Mortgage Loan) or the UBS Mortgage
Loan Seller (in the case of a UBS Trust Mortgage Loan) receives written notice
or obtains actual knowledge of a Document Defect or a Breach and such Document
Defect or Breach with respect to any Trust Mortgage Loan, as of the date
specified in the fourth paragraph of this Section 2.03(a) materially and
adversely affects the value of such Trust Mortgage Loan, then such Document
Defect shall constitute a "Material Document Defect" or such Breach shall
constitute a "Material Breach", as the case may be. In the event the Depositor
obtains actual knowledge of a Material Document Defect or Material Breach, then
the Depositor shall deliver written notification to the Trustee with respect
thereto.

          Promptly upon becoming aware of any such Material Document Defect or
Material Breach with respect to a UBS Trust Mortgage Loan, the Trustee shall
deliver a Seller/Depositor Notification to the UBS Mortgage Loan Seller, the
Master Servicer and the Special Servicer and shall require the UBS Mortgage Loan
Seller, within the time period and subject to the conditions provided for


                                     -132-



in the UBS/Depositor Mortgage Loan Purchase Agreement, except as otherwise
contemplated by Sections 2.03(d) and 2.03(e), to cure such Material Document
Defect or Material Breach, as the case may be, in all material respects, or
repurchase the affected Trust Mortgage Loan or any related REO Property (or, in
the case of an REO Property related to a Loan Combination, the Trust's interest
therein) at the applicable Purchase Price by wire transfer of immediately
available funds to the Pool Custodial Account. Promptly upon becoming aware of
any such Material Document Defect or Material Breach with respect to a Lehman
Trust Mortgage Loan, the Trustee shall deliver a Seller/Depositor Notification
to the Depositor, the Master Servicer and the Special Servicer, and the
Depositor shall, subject to Sections 2.03(d), 2.03(e) and 2.03(f), (A) not later
than (1) 30 days after the Depositor and the Trustee have agreed upon the
existence of such Material Document Defect or Material Breach or (2) 30 days
after an arbitration panel makes a binding determination, in accordance with the
provisions of Section 2.03(i), that a Material Document Defect or Material
Breach exists or (B) in the case of a Material Document Defect or Material
Breach that affects whether a Lehman Trust Mortgage Loan is or will continue to
be a "qualified mortgage" within the meaning of the REMIC Provisions (a
"Qualified Mortgage"), not later than 90 days following the discovery by any
party of such Material Document Defect or Material Breach (and such 30-day or
90-day period, as applicable, in the case of clause (A)(1), (A)(2) or (B) (with
respect to a Lehman Trust Mortgage Loan), and any "Initial Resolution Period",
as defined in the UBS/Depositor Mortgage Loan Purchase Agreement (with respect
to a UBS Trust Mortgage Loan), as applicable, are each referred to herein as an
"Initial Resolution Period"), (i) cure such Material Document Defect or Material
Breach, as the case may be, in all material respects (which cure shall include
payment of any out-of-pocket expenses that are reasonably incurred and directly
attributable to pursuing such a claim based on such Material Document Defect or
Material Breach associated therewith) or (ii) if any such Material Document
Defect or Material Breach, as the case may be, cannot be cured within the
Initial Resolution Period, repurchase the affected Lehman Trust Mortgage Loan or
any related REO Property (or, in the case of an REO Property related to a Loan
Combination, the Trust's interest therein) at the applicable Purchase Price by
wire transfer of immediately available funds to the Pool Custodial Account;
provided, however, that if (w) such Material Document Defect or Material Breach
is capable of being cured but not within the Initial Resolution Period, (x) such
Material Document Defect or Material Breach, as the case may be, does not affect
whether any Lehman Trust Mortgage Loan is a Qualified Mortgage, (y) the
Depositor has commenced and is diligently proceeding with the cure of such
Material Document Defect or Material Breach, as the case may be, within the
Initial Resolution Period, and (z) the Depositor shall have delivered to the
Trustee an Officer's Certificate confirming that such Material Breach or
Material Document Defect, as the case may be, is not capable of being cured
within the applicable Initial Resolution Period, setting forth what actions the
Depositor is pursuing in connection with the cure thereof and stating that the
Depositor anticipates that such Material Breach or Material Document Defect, as
the case may be, will be cured within an additional period not to exceed either
90 days beyond the end of the applicable Initial Resolution Period (in the event
the Depositor and the Trustee have agreed upon the existence of such Material
Document Defect or Material Breach as described in clause (A)(1) of the second
sentence of this paragraph) or 45 days beyond the end of the applicable Initial
Resolution Period (in the event an arbitration panel has made a binding
determination, as described in clause (A)(2) of the second sentence of this
paragraph, that a Material Document Defect or Material Breach exists), then the
Depositor shall have such additional 90-day period or 45-day period, as the case
may be (such additional 90-day period or 45-day period, as the case may be (with
respect to a Lehman Trust Mortgage Loan), and any "Resolution Extension Period",
as defined in the UBS/Depositor Mortgage Loan Purchase Agreement (with respect
to a UBS Trust Mortgage Loan), as applicable, are each referred to herein as a
"Resolution Extension Period"), to complete such cure or, failing such, to
repurchase the affected Trust Mortgage Loan (or the related


                                     -133-



Mortgaged Property); and provided, further, that, if any such Material Document
Defect is still not cured after the applicable Initial Resolution Period and any
such applicable Resolution Extension Period solely due to the failure of the
Depositor to have received a recorded document, then the Depositor shall be
entitled to continue to defer its cure and repurchase obligations in respect of
such Material Document Defect so long as the Depositor certifies to the Trustee
every six months thereafter that the Material Document Defect is still in effect
solely because of its failure to have received the recorded document and that
the Depositor is diligently pursuing the cure of such defect (specifying the
actions being taken). The parties acknowledge that neither delivery of a
certification or schedule of exceptions to the Depositor (in the case of a
Lehman Trust Mortgage Loan) or the UBS Mortgage Loan Seller (in the case of a
UBS Trust Mortgage Loan) pursuant to Section 2.02(b) or otherwise nor possession
of such certification or schedule by the Depositor (in the case of a Lehman
Trust Mortgage Loan) or the UBS Mortgage Loan Seller (in the case of a UBS Trust
Mortgage Loan) shall, in and of itself, constitute delivery of notice of any
Material Document Defect or Material Breach or knowledge or awareness by the
Depositor or the UBS Mortgage Loan Seller, as the case may be, of any Material
Document Defect or Material Breach.

          If, during the period of deferral by the Depositor of its cure and
repurchase obligations as contemplated by the last proviso of the penultimate
sentence of the preceding paragraph, or during any comparable deferral by the
UBS Mortgage Loan Seller of its cure and repurchase obligations as provided in
Section 5 of the UBS/Depositor Mortgage Loan Purchase Agreement, as applicable,
the Trust Mortgage Loan that is the subject of the Material Document Defect
either becomes a Specially Serviced Trust Mortgage Loan or becomes the subject
of a proposed or actual assumption of the obligations of the related Mortgagor
under such Trust Mortgage Loan, then (i) any party to this Agreement that
becomes aware of such event shall deliver a Seller/Depositor Notification to
such effect (unless a Seller/Depositor Notification with respect to such event
has already been delivered by another party) to the Master Servicer, the Special
Servicer, the Trustee, the Depositor (in the case of a Lehman Trust Mortgage
Loan) and the UBS Mortgage Loan Seller (in the case of a UBS Trust Mortgage
Loan), and (ii) the Trustee, upon becoming aware of such event, shall deliver a
Seller/Depositor Notification to the Master Servicer, the Special Servicer, the
Depositor (in the case of a Lehman Trust Mortgage Loan) and the UBS Mortgage
Loan Seller (in the case of a UBS Trust Mortgage Loan), providing notice of such
event and directing the Depositor or the UBS Mortgage Loan Seller, as
applicable, to cure the subject Material Document Defect within 15 days of
receipt of such Seller/Depositor Notification. If, upon the expiration of such
15-day period, the Depositor or the UBS Mortgage Loan Seller, as applicable, has
failed to cure the subject Material Document Defect, the Master Servicer or the
Special Servicer, as applicable, shall be entitled (but not obligated) to
perform the obligations of the Depositor or the UBS Mortgage Loan Seller, as
applicable, with respect to curing the subject Material Document Defect; and,
upon electing to perform such obligations, the Master Servicer or the Special
Servicer, as applicable, shall promptly deliver a Seller/Depositor Notification
to such effect. In connection with the preceding sentence, the Depositor will,
and the UBS Mortgage Loan Seller will be obligated under the UBS/Depositor
Mortgage Loan Purchase Agreement to, pay all reasonable actual out-of-pocket
costs and expenses in connection with the applicable servicer's effecting such
cure.

          Provided that if any Seller/Depositor Notification with respect to a
Material Document Defect or Material Breach is received by the Depositor (in the
case of a Lehman Trust Mortgage Loan) or the UBS Mortgage Loan Seller (in the
case of a UBS Trust Mortgage Loan), in accordance with the provisions of this
Section 2.03, within 24 months of the Closing Date, the material and adverse
effect of the subject Document Defect or Breach shall be determined as of the
date of the Mortgage Loan


                                     -134-



Purchase Agreements. After the expiration of 24 months following the Closing
Date, the material and adverse effect of any Document Defect or Breach that was
not the subject of another Seller/Depositor Notification received by the
Depositor (in the case of a Lehman Trust Mortgage Loan) or the UBS Mortgage Loan
Seller (in the case of a UBS Trust Mortgage Loan), in accordance with the
provisions of this Section 2.03, within 24 months of the Closing Date, shall be
determined as of the date of such Seller/Depositor Notification.

          If, in connection with any Material Breach, the Depositor is obligated
to repurchase any Lehman Trust Mortgage Loan pursuant to this Section 2.03,
and/or the UBS Mortgage Loan Seller is obligated to repurchase any UBS Trust
Mortgage Loan pursuant to the UBS/Depositor Mortgage Loan Purchase Agreement,
then such obligation shall extend to any REO Trust Mortgage Loan with respect
thereto; provided that (i) the subject Material Breach existed as to the subject
predecessor Trust Mortgage Loan prior to the date the related Mortgaged Property
became an REO Property or within 90 days thereafter, and (ii) the party having
the repurchase obligation had received, no later than 90 days following the date
on which the related Mortgaged Property became an REO Property, a
Seller/Depositor Notification from the Trustee regarding the occurrence of the
subject Material Breach and directing such party to repurchase the subject Trust
Mortgage Loan.

          (b) In connection with the events in Section 2.03(a), the Trustee
shall prepare and deliver, in each case promptly upon becoming aware of such
event, to the Master Servicer, the Special Servicer and either the Depositor
(with respect to a Lehman Trust Mortgage Loan) or the UBS Mortgage Loan Seller
(with respect to a UBS Trust Mortgage Loan), as applicable, a Seller/Depositor
Notification identifying and describing the circumstances identified in the
definition of "Seller/Depositor Notification" (unless, in the case of an event
described in clauses (iii), (iv) and/or (vi), as applicable, of the definition
of "Seller/Depositor Notification", a Seller/Depositor Notification with respect
to such event has already been delivered by the Master Servicer or the Special
Servicer). Further, in connection with the events in Section 2.03(a), the Master
Servicer or the Special Servicer, as applicable, shall prepare and deliver, in
each case promptly upon becoming aware of such event, to the other such
servicer, the Trustee and either the Depositor (with respect to a Lehman Trust
Mortgage Loan) or the UBS Mortgage Loan Seller (with respect to a UBS Trust
Mortgage Loan), as applicable, a Seller/Depositor Notification identifying and
describing the circumstances identified in clauses (iii), (iv) and/or (vi), as
applicable, of the definition of "Seller/Depositor Notification" (unless such
notification has already been delivered). A copy of each such Seller/Depositor
Notification shall also be delivered to the Controlling Class Representative
and, in the case of an event described in clauses (v) and/or (vii) of the
definition of "Seller/Depositor Notification", to either internal counsel to the
Depositor (with respect to a Lehman Trust Mortgage Loan) or counsel to the UBS
Mortgage Loan Seller (with respect to a UBS Trust Mortgage Loan), as applicable,
to the extent the Trustee, Master Servicer or Special Servicer, as applicable,
knows the identity of such person.

          (c) If one or more (but not all) of the Trust Mortgage Loans
constituting a Cross-Collateralized Group are to be repurchased by the Depositor
or the UBS Mortgage Loan Seller as contemplated by this Section 2.03, then,
prior to the subject repurchase, the Depositor or the UBS Mortgage Loan Seller,
as the case may be, or its designee shall use its reasonable efforts, subject to
the terms of the related Trust Mortgage Loan(s), to prepare and, to the extent
necessary and appropriate, have executed by the related Mortgagor and record,
such documentation as may be necessary to terminate the cross-collateralization
between the Trust Mortgage Loan(s) in such Cross-Collateralized Group that are
to be repurchased, on the one hand, and the remaining Trust Mortgage Loan(s)
therein,


                                     -135-



on the other hand, such that those two groups of Trust Mortgage Loans are each
secured only by the Mortgaged Properties identified in the Trust Mortgage Loan
Schedule as directly corresponding thereto; provided that no such termination
shall be effected unless and until (i) the Controlling Class Representative, if
one is then acting, has consented (which consent shall not be unreasonably
withheld and shall be deemed to have been given if no written objection is
received by the Depositor or the UBS Mortgage Loan Seller, as the case may be,
within ten (10) Business Days of the Controlling Class Representative's receipt
of a written request for such consent) and (ii) the Trustee has received from
the Depositor or the UBS Mortgage Loan Seller, as the case may be, (A) an
Opinion of Counsel to the effect that such termination would not cause an
Adverse REMIC Event to occur with respect to any REMIC Pool or an Adverse
Grantor Trust Event to occur with respect to the Grantor Trust and (B) written
confirmation from each Rating Agency that such termination would not cause an
Adverse Rating Event to occur with respect to any Class of Certificates; and
provided, further, that the Depositor, in the case of Lehman Trust Mortgage
Loans, or the UBS Mortgage Loan Seller, in the case of UBS Trust Mortgage Loans,
may, at its option, purchase the entire subject Cross-Collateralized Group in
lieu of effecting a termination of the cross-collateralization. All costs and
expenses incurred by the Trustee or any Person on its behalf pursuant to this
paragraph shall be included in the calculation of the Purchase Price for the
Trust Mortgage Loan(s) to be repurchased. If the cross-collateralization of any
Cross-Collateralized Group is not or cannot be terminated as contemplated by
this paragraph, then, for purposes of (i) determining whether the subject Breach
or Document Defect, as the case may be, materially and adversely affects the
value of such Cross-Collateralized Group and (ii) the application of remedies,
such Cross-Collateralized Group shall be treated as a single Trust Mortgage
Loan.

          (d) Notwithstanding the foregoing, if there exists a Breach of that
portion of the representation or warranty on the part of the Depositor set forth
in, or made pursuant to, paragraph (xlviii) of Schedule II hereto, or on the
part of the UBS Mortgage Loan Seller set forth in, or made pursuant to,
paragraph (xlviii) of Exhibit B to the UBS/Depositor Mortgage Loan Purchase
Agreement, in each case specifically relating to whether or not the Mortgage
Loan documents or any particular Mortgage Loan document for any Mortgage Loan
requires the related Mortgagor to bear the reasonable costs and expenses
associated with the subject matter of such representation or warranty, as set
forth in such representation or warranty, then the Master Servicer shall (and
the Special Servicer may) direct the Depositor (in the case of a Lehman Trust
Mortgage Loan) or the UBS Mortgage Loan Seller (in the case of a UBS Trust
Mortgage Loan) in writing to wire transfer to the Pool Custodial Account, within
90 days of such party's receipt of such direction, the amount of any such
reasonable costs and expenses incurred by the Trust that (i) are due from the
Mortgagor, (ii) otherwise would have been required to be paid by the Mortgagor
if such representation or warranty with respect to such costs and expenses had
in fact been true, as set forth in the related representation or warranty, (iii)
have not been paid by the Mortgagor, (iv) are the basis of such Breach and (v)
constitute "Covered Costs". Upon payment of such costs, the Depositor (in the
case of a Lehman Trust Mortgage Loan) or the UBS Mortgage Loan Seller (in the
case of a UBS Trust Mortgage Loan) shall be deemed to have cured such Breach in
all respects. Provided that such payment is made, this paragraph describes the
sole remedy available to the Certificateholders and the Trustee on their behalf
regarding any such Breach, regardless of whether it constitutes a Material
Breach, and neither the Depositor (in the case of a Lehman Trust Mortgage Loan)
nor the UBS Mortgage Loan Seller (in the case of a UBS Trust Mortgage Loan)
shall be obligated to otherwise cure such Breach or repurchase the affected
Trust Mortgage Loan under any circumstances. Amounts deposited in the Pool
Custodial Account pursuant to this paragraph shall constitute "Liquidation
Proceeds" for all purposes of this Agreement (other than Section 3.11(c)).


                                     -136-



          (e) Subject to the penultimate sentence of this paragraph and subject
to Section 2.03(d), if the Depositor determines that a Material Breach (other
than a Material Breach of a representation or warranty on the part of the
Depositor set forth in, or made pursuant to, paragraph (xvii) of Schedule II
hereto) or a Material Document Defect with respect to a Lehman Trust Mortgage
Loan is not capable of being cured in accordance with Section 2.03(a), or the
UBS Mortgage Loan Seller determines that a Material Breach (other than a
Material Breach of a representation or warranty on the part of the UBS Mortgage
Loan Seller set forth in, or made pursuant to, paragraph (xvii) of Exhibit B to
the UBS/Depositor Mortgage Loan Purchase Agreement) or Material Document Defect
with respect to a UBS Trust Mortgage Loan is not capable of being cured in
accordance with Section 5(a) of the UBS/Depositor Mortgage Loan Purchase
Agreement, then in lieu of repurchasing such Trust Mortgage Loan the Depositor
or the UBS Mortgage Loan Seller, as the case may be, may, at its sole option,
pay a cash amount equal to the loss of value (each such payment, a "Loss of
Value Payment") with respect to such Trust Mortgage Loan, which loss of value is
directly attributed to such Material Breach or Material Document Defect, as the
case may be. The amount of each such Loss of Value Payment shall be determined
either (i) by mutual agreement of the Special Servicer on behalf of the Trust
with respect to the subject Material Breach or Material Document Defect, as the
case may be, and either the Depositor or the UBS Mortgage Loan Seller, as the
case may be, or (ii) by an arbitration panel pursuant to a binding arbitration
proceeding in accordance with Section 2.03(i); provided that, in the event there
is an arbitration proceeding for determining the existence of a Material Breach
or a Material Document Defect with respect to any Trust Mortgage Loan, such
arbitration proceeding must also include a determination of the amount of the
loss of value to such Trust Mortgage Loan directly attributed to such Material
Breach or such Material Document Defect, as the case may be. Provided that such
payment is made, this paragraph describes the sole remedy available to the
Certificateholders and the Trustee on their behalf regarding any such Material
Breach or Material Document Defect and neither the Depositor (in the case of a
Lehman Trust Mortgage Loan) nor the UBS Mortgage Loan Seller (in the case of a
UBS Trust Mortgage Loan) shall be obligated to otherwise cure such Material
Breach or Material Document Defect or repurchase the affected Mortgage Loan
based on such Material Breach or Material Document Defect under any
circumstances. Notwithstanding the foregoing provisions of this Section 2.03(e),
if 95% or more of the loss of value to a Mortgage Loan was caused by a Material
Breach or Material Document Defect, which Material Breach or Material Document
Defect is not capable of being cured, then this Section 2.03(e) shall not apply,
and the Depositor (in the case of a Lehman Trust Mortgage Loan) or the UBS
Mortgage Loan Seller (in the case of a UBS Trust Mortgage Loan) shall be
obligated to repurchase the affected Mortgage Loan at the applicable Purchase
Price in accordance with Section 2.03(a); and, furthermore, neither the
Depositor nor the UBS Mortgage Loan Seller shall have the option of delivering
Loss of Value Payments in connection with any Material Breach relating to a
Trust Mortgage Loan's failure to be a Qualified Mortgage. In the event there is
a Loss of Value Payment made by the Depositor or the UBS Mortgage Loan Seller,
as the case may be, in accordance with this Section 2.03(e), the amount of such
Loss of Value Payment shall be deposited into the Loss of Value Reserve Fund to
be applied in accordance with Section 3.05(e).

          In the event the amount of any Loss of Value Payment is determined by
an arbitration panel pursuant to a binding arbitration proceeding in accordance
with Section 2.03(i), then such Loss of Value Payment shall also include the
payment of any costs and expenses (including costs incurred in establishing the
amount of any related loss of value to the subject Trust Mortgage Loan,
including reasonable legal fees) that are reasonably incurred in good faith by
the Master Servicer, the Special Servicer and/or the Trustee (on behalf of the
Trust) in enforcing the rights of the Trust against the Depositor or the UBS
Mortgage Loan Seller, as applicable, with respect to the subject Material Breach


                                     -137-



or Material Document Defect, as the case may be; provided that, if the Depositor
(with respect to a Lehman Trust Mortgage Loan) or the UBS Mortgage Loan Seller
(with respect to a UBS Trust Mortgage Loan) tenders a loss of value payment in a
specified amount in connection with a Material Breach or Material Document
Defect, as the case may be, prior to the institution of arbitration proceedings
and that offer is rejected, and if an amount equal to or less than the loss of
value payment originally tendered by the Depositor or the UBS Mortgage Loan
Seller, as the case may be, is ultimately determined by an arbitration panel
pursuant to a binding arbitration proceeding, in accordance with Section
2.03(i), to be the actual amount of the Loss of Value Payment attributed to such
Material Breach or Material Document Defect, as the case may be, then that Loss
of Value Payment shall not include the payment of any costs or expenses incurred
in enforcing the rights of the Trust against the Depositor or the UBS Mortgage
Loan Seller, as applicable, with respect to the subject Material Breach or
Material Document Defect, as the case may be; and provided, further, that, if
the Special Servicer requests a loss of value payment from the Depositor or the
UBS Mortgage Loan Seller, as the case may be, of a specified amount in
connection with a Material Breach or Material Document Defect, as the case may
be, and the Depositor or the UBS Mortgage Loan Seller, as the case may be,
refuses to pay that amount, and if an amount equal to or greater than the loss
of value payment originally requested by the Special Servicer is ultimately
determined by an arbitration panel pursuant to a binding arbitration proceeding,
in accordance with Section 2.03(i), to be the actual Loss of Value Payment
attributable to such Material Document Defect or Material Breach, then that Loss
of Value Payment shall also include the payment of any costs or expenses
reasonably incurred in good faith in enforcing the rights of the Trust against
the Depositor or the UBS Mortgage Loan Seller, as applicable, with respect to
the subject Material Breach or Material Document Defect, as the case may be; and
provided, further, that, if the Depositor (with respect to a Lehman Trust
Mortgage Loan) or the UBS Mortgage Loan Seller (with respect to a UBS Trust
Mortgage Loan) tenders a loss of value payment in connection with a Material
Breach or Material Document Defect, as the case may be, in a specified amount,
and the Special Servicer rejects such tender and requests a greater loss of
value payment amount, and an amount in between the respective amounts tendered
and requested is ultimately determined by an arbitration panel pursuant to a
binding arbitration proceeding, in accordance with Section 2.03(i), to be the
actual Loss of Value Payment attributable to such Material Breach or Material
Document Defect, as the case may be, then that Loss of Value Payment shall also
include the payment of an amount equal to the product of (i) all costs and
expenses reasonably incurred in connection with that arbitration proceeding,
multiplied by (ii) a fraction, the numerator of which is the excess of the
amount determined by that arbitration proceeding over the amount tendered by the
Depositor or the UBS Mortgage Loan Seller, as the case may be, and the
denominator of which is the excess of the amount requested by the Special
Servicer over the amount tendered by the Depositor or the UBS Mortgage Loan
Seller, as the case may be. Notwithstanding the foregoing, in the event any Loss
of Value Payment is determined by the parties hereto by mutual agreement (and
not by an arbitration proceeding), that Loss of Value Payment shall not include
any costs and expenses incurred by the Master Servicer, the Special Servicer or
the Trustee unless such costs and expenses were specifically included in such
mutual agreement.

          (f) Notwithstanding the foregoing, if there exists a Material Breach
of the representation or warranty on the part of the Depositor set forth in, or
made pursuant to, paragraph (xvii) of Schedule II hereto or the UBS Mortgage
Loan Seller set forth in, or made pursuant to, paragraph (xvii) of Exhibit B to
the UBS/Depositor Mortgage Loan Purchase Agreement, and the subject Mortgage
Loan becomes a Qualified Mortgage prior to the expiration of the Initial
Resolution Period applicable to a Material Document Defect or Material Breach
that affects whether a Mortgage Loan is a Qualified Mortgage, and without
otherwise causing an Adverse REMIC Event or an Adverse Grantor Trust Event,


                                     -138-



then such breach will be cured and the Depositor or the UBS Mortgage Loan
Seller, as the case may be, will not be obligated to repurchase or otherwise
remedy such Breach.

          (g) In connection with any purchase or repurchase of a Trust Mortgage
Loan pursuant to or otherwise as contemplated by this Section 2.03, the Trustee,
the Custodian, the Master Servicer and the Special Servicer shall each tender to
the purchasing/repurchasing entity, upon delivery to each of them of a receipt
executed by the purchasing/repurchasing entity, all portions of the Mortgage
File and other documents pertaining to such Trust Mortgage Loan possessed by it,
and each document that constitutes a part of the Mortgage File shall be endorsed
or assigned to the extent necessary or appropriate to the
purchasing/repurchasing entity or its designee in the same manner, but only if
the respective documents have been previously assigned or endorsed to the
Trustee, and pursuant to appropriate forms of assignment, substantially similar
to the manner and forms pursuant to which such documents were previously
assigned to the Trustee; provided that such tender by the Trustee or by a
Custodian on its behalf shall be conditioned upon its receipt from the Master
Servicer of a Request for Release accompanied by a certification of a Servicing
Officer to the effect that all amounts received or to be received in connection
with such purchase or repurchase, as the case may be, which are required to be
deposited in the Pool Custodial Account pursuant to Section 3.04(a) have been
deposited. The Master Servicer shall, and is hereby authorized and empowered by
the Trustee to, prepare, execute and deliver in its own name, on behalf of the
Certificateholders and the Trustee or any of them, the endorsements and
assignments contemplated by this Section 2.03(g), and such other instruments as
may be necessary or appropriate to transfer title to an REO Property or any
interest therein in connection with the repurchase of an REO Trust Mortgage Loan
and the Trustee shall execute and deliver any powers of attorney necessary to
permit the Master Servicer to do so; provided, however, that the Trustee shall
not be held liable for any misuse of any such power of attorney by the Master
Servicer.

          (h) The UBS/Depositor Mortgage Loan Purchase Agreement provides the
sole remedies available to the Certificateholders, or the Trustee on behalf of
the Certificateholders, respecting any Document Defect or Breach with respect to
any UBS Trust Mortgage Loan. This Section 2.03 provides the sole remedies
available to the Certificateholders, or the Trustee on behalf of the
Certificateholders, respecting any Document Defect or Breach with respect to any
Lehman Trust Mortgage Loan. Any purchase of a Trust Mortgage Loan pursuant to or
as contemplated by this Section 2.03 shall be on a whole loan, servicing release
basis.

          (i) The parties hereto agree that any controversy or claim arising
under Section 5(a), Section 5(b) and/or Section 5(g) of the UBS/Depositor
Mortgage Loan Purchase Agreement shall be resolved in accordance with the
Mediation/Arbitration procedures set forth in Section 5(i) of the UBS/Depositor
Mortgage Loan Purchase Agreement. In addition, subject to the prior sentence,
and without intending to create any overlap between the prior sentence and this
sentence, the parties hereto further agree that any controversy or claim (a
"Dispute") involving a Lehman Trust Mortgage Loan and/or the Depositor and
arising under Section 2.03(a) and/or Section 2.03(e) of this Agreement shall be
resolved in accordance with the following Mediation/Arbitration procedures set
forth in this Section 2.03(i).

          If the Depositor receives a Seller/Depositor Notification pursuant to
Section 2.03(a) of this Agreement regarding the alleged existence of a Material
Document Defect or Material Breach with respect to any Lehman Trust Mortgage
Loan and requesting the Depositor to cure or repurchase the affected Lehman
Trust Mortgage Loan in connection therewith (a "Notice"), and the Depositor does
not


                                     -139-



agree upon the existence of such Material Document Defect or Material Breach
within 90 days of receiving such Notice, then, unless otherwise agreed to by the
parties involved in the Dispute, that Dispute shall be submitted to non-binding
mediation in accordance with the provisions of this paragraph; provided, that if
the Depositor is proceeding to cure the subject Material Document Defect or
Material Breach, then that Dispute shall not be submitted to mediation until the
expiration of the related Resolution Extension Period and the failure of the
Depositor to complete such cure (unless otherwise agreed to by the parties
involved in the Dispute). Following the 90-day period referred to in the
preceding sentence and subject to the preceding proviso, any party to this
Agreement that is involved in the Dispute may send a written letter (a
"Mediation Letter") to another party to this Agreement that they wish the
mediation process to begin between the sender and the recipient of such
Mediation Letter. Following receipt of a Mediation Letter, a mediator(s) shall
be selected by agreement of the parties to the mediation. If such parties cannot
agree on a mediator, then the mediation shall be conducted by three mediators,
one of which shall be selected by the Depositor and one of which shall be
selected by the Trustee or its designee. Each of the parties to the mediation
shall submit the name of the Person it has selected to serve as a mediator to
the opposing party within 10 days of the date of the Mediation Letter. If either
party fails to submit the name of its selected mediator within 10 days of the
date of the Mediation Letter, the other party shall have the right to select the
second mediator in addition to its own mediator (provided that such party has
submitted the name of its selected mediator within 10 days of the date of the
Mediation Letter). The two mediators selected by the party(ies) shall appoint a
third mediator within 20 days of the date of the Mediation Letter or such longer
time period as agreed to by the parties to the mediation. Any mediator(s) so
designated must be acceptable to both (i) the Depositor and (ii) the Trustee,
the Master Servicer or the Special Servicer, whichever such party is the party
to the mediation on behalf of the Trust (or such party's designee). Any
mediators appointed or selected pursuant to the provisions of this paragraph
must be experienced professionals in the CMBS industry.

          Any mediation related to a particular Dispute and commenced in
accordance with the preceding paragraph must be completed within 90 days of the
date of the Mediation Letter (or a longer period, if the parties to the
mediation agreed to extend the mediation). Any mediation referred to in this
Section 2.03(i) shall be conducted in the manner specified by the mediator(s)
and agreed upon by both (i) the Depositor and (ii) the Trustee, the Master
Servicer or the Special Servicer, whichever such party is the party to the
mediation on behalf of the Trust (or such party's designee), and any such
mediation shall be conducted in New York City to the exclusion of all other
locations (unless otherwise agreed to by the parties to the mediation). During
the mediation process, the parties to the mediation shall discuss their
differences voluntarily and in good faith and attempt, with the assistance of
the mediator(s) as a facilitator of the negotiations, to reach an amicable
resolution of the Dispute. The mediation will be treated as a settlement
discussion and therefore will be confidential. No mediator selected in
accordance with this Section 2.03(i) may testify for either party in any later
proceeding relating to the Dispute. No recording or transcript shall be made of
the mediation proceedings. The fees and expenses of all mediator(s) shall be
shared equally by the parties to the mediation; provided, however, that the
party to the mediation that is acting on behalf of the Trust in accordance with
the provisions of this Section 2.03(i) or Section 5(i) of the UBS/Depositor
Mortgage Loan Purchase Agreement shall, if and to the extent permitted under
Section 6.03 or Section 8.05(b), as applicable, be entitled to reimbursement or
indemnification by the Trust Fund for such fees and expenses.

          Notwithstanding anything to the contrary herein, no party shall be
required to agree to a Dispute resolution pursuant to mediation and no decision
or resolution of a mediator or mediators shall be binding on any party unless
such decision or resolution is expressly agreed to by such party. In the


                                     -140-



event the parties involved in the Dispute have not agreed to a Dispute
resolution pursuant to mediation at the termination of the mediation, then that
Dispute will be settled by arbitration in accordance with the succeeding
paragraphs of this Section 2.03(i).

          If a Dispute has not been resolved within 90 days of the date of the
Mediation Letter (or such shorter or longer period as is expressly agreed to by
the parties to the mediation), the mediation shall terminate and the Dispute
will be settled by arbitration. Following the date of termination of mediation,
which shall be the date occurring 90 days after the date of the Mediation Letter
unless otherwise expressly agreed to by the parties to the mediation,
arbitration may be commenced by any party to this Agreement involved in the
Dispute sending a written notice to another party to this Agreement involved in
the Dispute that they wish the arbitration process to begin with respect to the
Dispute between the sender and the recipient of such written notice. The date
any such party receives written notice in accordance with this Section 2.03(i)
from another party that such party wishes to commence arbitration shall be
referred to as the "Arbitration Commencement Date". Any arbitration hereunder
shall be conducted in accordance with the provisions of this Agreement and the
American Arbitration Association Rules for Large Complex Commercial Disputes
("AAA Rules"), but shall not be conducted by the American Arbitration
Association ("AAA"). Discovery will be permitted in connection with the
arbitration in accordance with the AAA Rules. In the event of a conflict, the
provisions of this Agreement will control. Such arbitration shall be conducted
before a panel of three arbitrators, regardless of the size of the Dispute. The
arbitration panel shall consist of one person selected by the Depositor and one
person selected by the Trustee, the Master Servicer or the Special Servicer,
whichever such party is the party to the arbitration on behalf of the Trust (or
such party's designee). Each such party shall submit the name of the person it
has selected to serve as an arbitrator to the other party within 30 days of the
Arbitration Commencement Date (or such longer period as is expressly agreed to
by the parties to the arbitration). If either such party fails to submit the
name of its selected arbitrator within 30 days of the Arbitration Commencement
Date, then the other such party shall have the right to select the second
arbitrator in addition to its own arbitrator (provided that such party has
submitted the name of its selected arbitrator within 30 days of the Arbitration
Commencement Date). The two arbitrators designated in accordance with the two
preceding sentences shall appoint a third arbitrator within 45 days of the
Arbitration Commencement Date (or such longer period as is expressly agreed to
by the parties to the arbitration). All arbitrators appointed or selected
pursuant to the provisions of this paragraph must be experienced professionals
in the CMBS industry. The third arbitrator shall be an Independent person who
has not previously been employed by either party and does not have a direct or
indirect interest in either party or the subject matter of the arbitration. The
two (2) arbitrators appointed by the parties to the arbitration are not required
to be neutral and it shall not be grounds for removal of either of such
arbitrators or for vacating an arbitration award that either of such arbitrators
has past or present relationships with the party that appointed such arbitrator.
No potential arbitrator may serve on the panel unless he or she has agreed in
writing to abide and be bound by the terms and provisions of this Agreement and
the AAA Rules and to keep confidential the terms of any arbitration proceeding
related to this Agreement and the terms of any discussion, negotiation,
decision, agreement or resolution in connection therewith.

          Any issue concerning the extent to which any Dispute is subject to
arbitration, or concerning the applicability, interpretation, or enforceability
of these procedures, including any contention that all or part of these
procedures are invalid or unenforceable, shall be resolved by the arbitrators.
In no event, notwithstanding that any provision of this Agreement is held to be
invalid or unenforceable, shall the arbitrators have the power to make an award
or impose a remedy that could not


                                     -141-



be made or imposed by a court deciding the matter in the same jurisdiction. In
no event shall the arbitrators have the power to make an award or impose a
remedy that is not contemplated by, or conflicts with the terms and provisions
of, this Agreement (other than any term or provision of this Agreement that is
held to be invalid or unenforceable). Without limiting the foregoing, the
arbitrators shall have no authority to award treble, consequential or punitive
damages of any type under any circumstances, whether or not such damages may be
available under the AAA Rules or any other act or law. Subject to the provisions
of this Agreement, the result of the arbitration will be binding on the parties
involved in the Dispute, and judgment on the arbitrators' award may be entered,
subject to the provisions of Section 11.04 of this Agreement, in any court of
competent jurisdiction.

          All mediations and arbitrations shall be conducted in New York City to
the exclusion of all other locations (unless otherwise expressly agreed to by
the parties to the subject mediation or arbitration, as applicable). The party
to an arbitration that is acting on behalf of the Trust in accordance with the
provisions of this Section 2.03(i) or Section 5(i) of the UBS/Depositor Mortgage
Loan Purchase Agreement shall, if and to the extent permitted under Section 6.03
or Section 8.05(b), as applicable, be entitled to reimbursement or
indemnification by the Trust Fund for the fees and expenses incurred in
connection therewith.

          The parties to this Agreement hereby agree to waive any right to trial
by jury fully to the extent that any such right shall now or hereafter exist
with regard to the rights and remedies contained in this Section 2.03(i);
provided, that if (i) any party to an arbitration governed by this Section
2.03(i) fails to abide by the rules or deadlines for that arbitration (as such
deadlines may be extended by express agreement of the parties to that
arbitration), or (ii) the applicable appointed arbitrators determine that the
subject Dispute cannot be resolved through arbitration either because the AAA
Rules are inapplicable to the Dispute and/or the Federal Arbitration Act is
inapplicable to the Dispute or for any other reason, then the other party (in
the case of clause (i)) or any party (in the case of clause (ii)) to this
Agreement involved in such arbitration may in its sole option, file a complaint
to resolve the Dispute through a legal proceeding and in accordance with the
provision contained in Section 11.04 hereof.

          If any of the provisions of this Section 2.03(i) are determined by a
court of law to be invalid or unenforceable, the remaining provisions shall
remain in effect and be binding on the parties involved in the Dispute to the
fullest extent permitted by law.

          (j) In the event that the Master Servicer receives notice from the
Mortgagor under any Early Defeasance Trust Mortgage Loan that (i) such Mortgagor
intends to defease such Early Defeasance Trust Mortgage Loan in whole on or
before the second anniversary of the Closing Date and the cash amount tendered
by such Mortgagor to purchase Defeasance Collateral or other permitted
collateral in order to defease such Early Defeasance Trust Mortgage Loan (in
accordance with the related loan documents) is less than the Purchase Price that

                                     -142-

Mortgagor's intention, and the Trustee shall direct the Depositor (with respect

Mortgage Loan Seller, with respect to a UBS Trust Mortgage Loan, pursuant to the
UBS/Depositor Mortgage Loan Purchase Agreement, has agreed to repurchase) such
Trust Mortgage Loan at a price equal to (A) the Purchase Price that would be
applicable in the event of a repurchase of such Trust Mortgage Loan in

Loan Purchase Agreement (in the case of a UBS Trust Mortgage Loan) is obligated
to pay, all reasonable costs and expenses, including the costs of any Opinions
of Counsel, in connection with any such "qualified liquidation" of a Loan REMIC

          SECTION 2.04.  Representations, Warranties and Covenants of the
                         Depositor.

          (a) The Depositor hereby represents, warrants and covenants to the
Trustee, for its own benefit and the benefit of the Certificateholders, and to
the Master Servicer and the Special Servicer, as of the Closing Date, that:

               (i) The Depositor is a corporation duly organized, validly
     existing and in good standing under the laws of the State of Delaware.

               (ii) The execution and delivery of this Agreement by the
     Depositor, and the performance and compliance with the terms of this
     Agreement by the Depositor, will not violate the Depositor's certificate of
     incorporation or by-laws or constitute a default (or an event which, with
     notice or lapse of time, or both, would constitute a default) under, or
     result in the breach of, any material agreement or other instrument to
     which it is a party or which is applicable to it or any of its assets.

               (iii) The Depositor has the full power and authority to enter
     into and consummate all transactions contemplated by this Agreement, has
     duly authorized the execution, delivery and performance of this Agreement,
     and has duly executed and delivered this Agreement.

               (iv) This Agreement, assuming due authorization, execution and
     delivery by each of the other parties hereto, constitutes a valid, legal
     and binding obligation of the Depositor, enforceable against the Depositor
     in accordance with the terms hereof, subject to (A) applicable bankruptcy,
     insolvency, reorganization, moratorium and other laws affecting the
     enforcement of


                                     -143-



     creditors' rights generally, and (B) general principles of equity,
     regardless of whether such enforcement is considered in a proceeding in
     equity or at law.

               (v) The Depositor is not in violation of, and its execution and
     delivery of this Agreement and its performance and compliance with the
     terms of this Agreement will not constitute a violation of, any law, any
     order or decree of any court or arbiter, or any order, regulation or demand
     of any federal, state or local governmental or regulatory authority, which
     violation, in the Depositor's good faith and reasonable judgment, is likely
     to affect materially and adversely either the ability of the Depositor to
     perform its obligations under this Agreement or the financial condition of
     the Depositor.

               (vi) The transfer of the Trust Mortgage Loans to the Trustee as
     contemplated herein requires no regulatory approval, other than any such
     approvals as have been obtained, and is not subject to any bulk transfer or
     similar law in effect in any applicable jurisdiction.

               (vii) The Depositor is not transferring the Trust Mortgage Loans
     to the Trustee with any intent to hinder, delay or defraud its present or
     future creditors.

               (viii) The Depositor has been solvent at all relevant times prior
     to, and will not be rendered insolvent by, its transfer of the Trust
     Mortgage Loans to the Trustee pursuant to Section 2.01(a).

               (ix) After giving effect to its transfer of the Trust Mortgage
     Loans to the Trustee pursuant to Section 2.01(a), the value of the
     Depositor's assets, either taken at their present fair saleable value or at
     fair valuation, will exceed the amount of the Depositor's debts and
     obligations, including contingent and unliquidated debts and obligations of
     the Depositor, and the Depositor will not be left with unreasonably small
     assets or capital with which to engage in and conduct its business.

               (x) The Depositor does not intend to, and does not believe that
     it will, incur debts or obligations beyond its ability to pay such debts
     and obligations as they mature.

               (xi) No proceedings looking toward merger, liquidation,
     dissolution or bankruptcy of the Depositor are pending or contemplated.

               (xii) No litigation is pending or, to the best of the Depositor's
     knowledge, threatened against the Depositor that, if determined adversely
     to the Depositor, would prohibit the Depositor from entering into this
     Agreement or that, in the Depositor's good faith and reasonable judgment,
     is likely to materially and adversely affect either the ability of the
     Depositor to perform its obligations under this Agreement or the financial
     condition of the Depositor.

               (xiii) Except for any actions that are the express responsibility
     of another party hereunder or under the Mortgage Loan Purchase Agreements,
     and further except for actions that the Depositor is expressly permitted to
     complete subsequent to the Closing Date, the Depositor has taken all
     actions required under applicable law to effectuate the transfer of the
     Trust Mortgage Loans by the Depositor to the Trustee.


                                     -144-



               (xiv) Immediately prior to the transfer of the UBS Trust Mortgage
     Loans to the Trust pursuant to this Agreement (and assuming that the UBS
     Mortgage Loan Seller transferred to the Depositor good and marketable title
     to each UBS Trust Mortgage Loan, free and clear of all liens, claims,
     encumbrances and other interests), (A) the Depositor had good and
     marketable title to, and was the sole owner and holder of, each UBS Trust
     Mortgage Loan; and (B) the Depositor has full right and authority to sell,
     assign and transfer the UBS Trust Mortgage Loans, exclusive of the
     servicing rights pertaining thereto.

          (b) The Depositor hereby makes to the Trustee, for the Trustee's own
benefit and the benefit of the Certificateholders, with respect to each Lehman
Trust Mortgage Loan only, the representations and warranties shown on Schedule
II hereto, as of the Closing Date or such other date specified in the particular
representation and warranty, subject to the exceptions set forth on Schedule III
hereto (the headings set forth in Schedule II hereto with respect to each
representation and warranty being for convenience of reference only and in no
way limiting, expanding or otherwise affecting the scope or subject matter
thereof).

          Except as expressly provided in Section 2.04(a), the Depositor does
not make any representations or warranties regarding the UBS Trust Mortgage
Loans.

          (c) The representations, warranties and covenants of the Depositor set
forth in or made pursuant to Section 2.04(a) and Section 2.04(b) shall survive
the execution and delivery of this Agreement and shall inure to the benefit of
the Persons for whose benefit they were made for so long as the Trust Fund
remains in existence. Upon discovery by any party hereto of any breach of any of
such representations, warranties and covenants, the party discovering such
breach shall give prompt written notice thereof to the other parties.

                         Issuance of the Class V Certificates.

          (a) It is the intention of the parties hereto that the segregated pool
of assets consisting of any collections of Additional Interest Received by the

trust for federal income tax purposes. The Trustee, by its execution and

obligations with respect to the Grantor Trust, Grantor Trust Assets, Class V
Certificates, the Class V Sub-Account, ARD Mortgage Loans, ARD Trust Mortgage

                                   ARTICLE III

                 ADMINISTRATION AND SERVICING OF THE TRUST FUND

          SECTION 3.01.  Administration of the Mortgage Loans.

          (a) All of the Serviced Mortgage Loans and Administered REO Properties
are to be serviced and administered by the Master Servicer and/or the Special
Servicer hereunder. Each of the Master Servicer and the Special Servicer shall
service and administer the Serviced Mortgage Loans and Administered REO
Properties that it is obligated to service and administer pursuant to this
Agreement on behalf of the Trustee, for the benefit of the Certificateholders
(or, in the case of a Serviced Loan Combination, for the benefit of the
Certificateholders and the related Serviced Non-Trust Mortgage Loan
Noteholder(s)), as determined in the good faith and reasonable judgment of the
Master Servicer or the Special Servicer, as the case may be, in accordance with:
(i) any and all applicable laws; (ii) the express terms of this Agreement; (iii)
the express terms of the respective Serviced Mortgage Loans and any and all
related intercreditor, co-lender or similar agreements (including with respect
to performing the duties of the holders of the respective Serviced Mortgage
Loans thereunder (to the extent not inconsistent with this Agreement and to the
extent consistent with the Servicing Standard)); and (iv) to the extent
consistent with the foregoing, the Servicing Standard. The Master Servicer or
the Special Servicer, as applicable in accordance with this Agreement, shall
service and administer each Cross-Collateralized Group as a single Serviced
Mortgage Loan as and when necessary and appropriate consistent with the
Servicing Standard. Without limiting the foregoing and subject to Section 3.21,
(i) the Master Servicer shall service and administer all of the Performing
Serviced Mortgage Loans and shall render such services with respect to the
Specially Serviced Mortgage Loans as are specifically provided for herein, and
(ii) the Special Servicer shall service and administer each Specially Serviced
Mortgage Loan and Administered REO Property and shall render such services with
respect to Performing Serviced Mortgage Loans as are specifically provided for
herein. All references herein to the respective duties of the Master Servicer
and the Special Servicer, and to the areas in which they may exercise
discretion, shall be subject to Section 3.21.

          (b) Subject to Sections 3.01(a), 3.20, 6.11 and 6.12, the Master
Servicer and the Special Servicer shall each have full power and authority,
acting alone (or, to the extent contemplated by Section 3.22 of this Agreement,
through subservicers), to do or cause to be done any and all things in
connection with the servicing and administration contemplated by Section 3.01(a)
that it may deem necessary or desirable. Without limiting the generality of the
foregoing, each of the Master Servicer and the Special Servicer, in its own
name, with respect to each of the Serviced Mortgage Loans it is obligated to
service hereunder, is authorized and empowered by the Trustee and, to the extent
provided in the related Co-Lender Agreement, each related Serviced Non-Trust
Mortgage Loan Noteholder (if any) to execute and deliver, on behalf of the
Certificateholders, the Trustee and such Serviced Non-Trust Mortgage Loan
Noteholder or any of them, (i) any and all financing statements, continuation
statements and other documents or instruments necessary to maintain the lien
created by any Mortgage or other security document in the related Mortgage File
on the related Mortgaged Property and related collateral; (ii) in accordance
with the Servicing Standard and subject to Sections 3.01(a), 3.20, 6.11 and
6.12, any and all modifications, extensions, waivers, amendments or consents to
or with respect to any documents contained in the related Mortgage File; (iii)
any and all instruments of satisfaction or cancellation, or of partial or full
release or discharge or of assignment, and all other comparable instruments; and
(iv) any


                                      -149-



and all instruments that such party may be required to execute on behalf of the
Trustee in connection with the defeasance of a Serviced Mortgage Loan as
contemplated in this Agreement. Subject to Section 3.10, the Trustee shall, at
the written request of the Master Servicer or the Special Servicer, promptly
execute any limited powers of attorney and other documents furnished by the
Master Servicer or the Special Servicer that are necessary or appropriate to
enable them to carry out their servicing and administrative duties hereunder;
provided, however, that the Trustee shall not be held liable for any misuse of
any such power of attorney by the Master Servicer or the Special Servicer.
Notwithstanding anything contained herein to the contrary, neither the Master
Servicer nor the Special Servicer shall, without the Trustee's written consent:
(i) initiate any action, suit or proceeding solely under the Trustee's name
without indicating the Master Servicer's or Special Servicer's, as applicable,
representative capacity; or (ii) take any action with the intent to cause, and
that actually causes, the Trustee to be registered to do business in any state.

          (c) The parties hereto acknowledge that each Loan Combination is
subject to the terms and conditions of the related Co-Lender Agreement; and,
with respect to each Loan Combination, the parties hereto further recognize the
respective rights and obligations of the Trust, as holder of the related
Combination Trust Mortgage Loan, and of the related Non-Trust Mortgage Loan
Noteholder(s) under the related Co-Lender Agreement.

          (d) With respect to any Serviced Loan Combination, in the event that
neither the related Trust Mortgage Loan nor the related REO Property (or any
interest therein) is an asset of the Trust Fund and, except as contemplated in
the second paragraph of this Section 3.01(d), in accordance with the related
Co-Lender Agreement, the servicing and administration of such Serviced Loan
Combination and any related REO Property are to be governed by a separate
servicing agreement and not by this Agreement, then (either (i) with the consent
or at the request of the holders of each Mortgage Loan comprising such Serviced
Loan Combination or (ii) if expressly provided for in the related Co-Lender
Agreement) the Master Servicer and, if such Serviced Loan Combination is then
being specially serviced hereunder or the related Mortgaged Property has become
an REO Property, the Special Servicer, shall continue to act in such capacities
under such separate servicing agreement; provided that such separate servicing
agreement shall be reasonably acceptable to the Master Servicer and/or the
Special Servicer, as the case may be, and shall contain servicing and
administration, limitation of liability, indemnification and servicing
compensation provisions substantially similar to the corresponding provisions of
this Agreement, except for the fact that such Serviced Loan Combination and the
related Mortgaged Property shall be the sole assets serviced and administered
thereunder and the sole source of funds thereunder.

          Further, with respect to any Serviced Loan Combination, if at any time
neither the related Trust Mortgage Loan nor any related REO Property (or any
interest therein) is an asset of the Trust Fund, and if a separate servicing
agreement with respect to such Serviced Loan Combination or any related REO
Property, as applicable, has not been entered into as contemplated by the
related Co-Lender Agreement and the prior paragraph (for whatever reason,
including the failure to obtain any rating agency confirmation required in
connection therewith pursuant to the related Co-Lender Agreement), and
notwithstanding that neither the related Trust Mortgage Loan nor any related REO
Property (or any interest therein) is an asset of the Trust Fund, then, unless
directed otherwise by the then current holders of the Mortgage Notes comprising
such Serviced Loan Combination, the Master Servicer and, if applicable, the
Special Servicer shall continue to service and administer such Serviced Loan
Combination and/or any related REO Property, for the benefit of the respective
holders of such Serviced


                                      -150-



Loan Combination, under this Agreement as if such Serviced Loan Combination or
any related REO Property were the sole assets subject hereto, with certain
references in this Agreement applicable to the Trust, the Trustee, the
Certificates, the Certificateholders (or any subgroup thereof) or any
representative of any such Certificateholders, all being construed to refer to
such similar terms as are applicable to the then current holder of the Mortgage
Note for the related Serviced Combination Trust Mortgage Loan.

          (e) The Master Servicer shall use efforts consistent with the
Servicing Standard to have prepared, executed (with the cooperation of the
Depositor (in the case of a Lehman Trust Mortgage Loan) and the UBS Mortgage
Loan Seller (in the case of a UBS Trust Mortgage Loan) in obtaining requisite
signatures, if applicable) and delivered by the applicable party (and included
in the Servicing File), not later than the later of (i) 30 days following the
Master Servicer's receipt of the subject franchisor comfort letter, guaranty of
payment or letter of credit and (ii) the expiration of the period that may be
required for such transfer or assignment pursuant to the terms of the applicable
franchisor comfort letter, guaranty of payment or letter of credit, if any, (A)
with respect to any Serviced Mortgage Loan secured by a hospitality property (as
identified on Schedule VI hereto) (and with respect to which a franchise
agreement constitutes part of the related Mortgage File on the Closing Date),
any original transfer or assignment documents necessary to transfer or assign to
the Trustee any rights under the related franchisor comfort letter; and (B) with
respect to any Serviced Mortgage Loan that has a related guaranty or letter of
credit that constitutes part of the related Mortgage File on the Closing Date,
any original transfer or assignment documents necessary to transfer or assign to
the Trustee any rights under the related guaranty of payment or letter of
credit. In the event, with respect to a Serviced Trust Mortgage Loan with a
related letter of credit, it is determined by the Master Servicer that a draw
under such letter of credit has become necessary under the terms thereof prior
to the assignment under clause (B) of the preceding sentence having been
effected, the Master Servicer shall direct (in writing) the Depositor (in the
case of a Lehman Trust Mortgage Loan) or the UBS Mortgage Loan Seller (in the
case of a UBS Trust Mortgage Loan) to make such draw or to cause such draw to be
made on behalf of the Trustee, and, the Depositor will, and the UBS Mortgage
Loan Seller will be obligated under the UBS/Depositor Mortgage Loan Purchase
Agreement to, use its best efforts to cause such draw to be made; provided that
neither the Depositor nor the UBS Mortgage Loan Seller shall have any liability
in connection with the determination to make, or the making of, such draw (other
than to remit the proceeds of such draw to the Master Servicer).

          (f) The relationship of each of the Master Servicer and the Special
Servicer to the Trustee, to the Serviced Non-Trust Mortgage Loan Noteholders and
to each other under this Agreement is intended by the parties to be that of an
independent contractor and not that of a joint venturer, partner or agent.

          (g) The parties hereto acknowledge that each Outside Serviced Trust
Mortgage Loan (and, if such Outside Serviced Trust Mortgage Loan is part of a
Loan Combination, the related Outside Serviced Non-Trust Mortgage Loan(s)) will
primarily be serviced and administered in accordance with the related Outside
Servicing Agreement, and the servicing and administrative duties of the parties
hereto with respect to each Outside Serviced Trust Mortgage Loan, any successor
REO Trust Mortgage Loan with respect thereto and any related Outside
Administered REO Property shall be limited to those expressly set forth herein.

          SECTION 3.02.  Collection of Mortgage Loan Payments.

          (a) Each of the Master Servicer and the Special Servicer shall
undertake reasonable efforts to collect all payments required under the terms
and provisions of the Serviced Mortgage Loans it is obligated to service
hereunder and shall follow such collection procedures as are consistent with the
Servicing Standard; provided, however, that neither the Master Servicer nor the
Special Servicer shall, with respect to any Serviced Mortgage Loan that
constitutes an ARD Mortgage Loan after its Anticipated Repayment Date, take any
enforcement action with respect to the payment of Additional Interest (other
than the making of requests for its collection), unless (i) the taking of an
enforcement action with respect to the payment of other amounts due under such
ARD Mortgage Loan is, in the good faith and reasonable judgment of the Special
Servicer, necessary, appropriate and consistent with the Servicing Standard or
(ii) all other amounts due under such ARD Mortgage Loan have been paid, the
payment of such Additional Interest has not been forgiven in accordance with
Section 3.20 and, in the good faith and reasonable judgment of the Special
Servicer, the Liquidation Proceeds expected to be recovered in connection with
such enforcement action will cover the anticipated costs of such enforcement
action and, if applicable, any associated interest accrued on Advances. The
Special Servicer shall ensure that, with respect to Specially Serviced Mortgage
Loans, the Mortgagors make payments directly to the Master Servicer; provided
that, in the event the Special Servicer receives a payment that should have been
made directly to the Master Servicer, the Special Servicer shall promptly
forward such payment to the Master Servicer. Upon receipt of any such payment
with respect to a Specially Serviced Mortgage Loan, the Master Servicer shall
promptly notify the Special Servicer, and the Special Servicer shall direct the
Master Servicer as to the proper posting of such payment. Consistent with the
foregoing, the Special Servicer, with regard to a Specially Serviced Mortgage
Loan, or the Master Servicer, with regard to a Performing Serviced Mortgage
Loan, may waive or defer any Default Charges in connection with collecting any
late payment on a Serviced Mortgage Loan; provided that without the consent of
the Special Servicer in the case of a proposed waiver by the Master Servicer, no
such waiver or deferral may be made by the Master Servicer pursuant to this
Section 3.02 if any Advance has been made as to such delinquent payment.

          (b) All amounts Received by the Trust with respect to any
Cross-Collateralized Group in the form of payments from Mortgagors, Insurance
Proceeds, Condemnation Proceeds and Liquidation Proceeds, shall be applied by
the Master Servicer among the Trust Mortgage Loans constituting such
Cross-Collateralized Group in accordance with the express provisions of the
related loan documents and, in the absence of such express provisions or to the
extent that such payments and other collections may be applied at the discretion
of the lender, on a pro rata basis in accordance with the respective amounts
then "due and owing" as to each such Mortgage Loan. Except as otherwise
contemplated by the following paragraphs in this Section 3.02(b), all amounts
Received by the Trust in respect of or allocable to any particular Trust
Mortgage Loan (whether or not such Trust Mortgage Loan constitutes part of a
Cross-Collateralized Group) in the form of payments from Mortgagors, Liquidation
Proceeds, Condemnation Proceeds or Insurance Proceeds shall be applied to
amounts due and owing under such Trust Mortgage Loan (including for principal
and accrued and unpaid interest) in accordance with the express provisions of
the related Mortgage Note, the related Mortgage and/or any related loan
agreement and, in the absence of such express provisions or to the extent that
such payments and other collections may be applied at the discretion of the
lender, as follows: first, as a recovery of any related unpaid servicing
expenses and unreimbursed Servicing Advances; second, as a recovery of accrued
and unpaid interest on such Trust Mortgage Loan at the related Mortgage Rate
(net, in the case of an Outside Serviced Trust Mortgage Loan, of related Outside
Servicing Fees) to, but not including, the date of


                                      -152-



receipt (or, in the case of a full Monthly Payment from any Mortgagor, through
the related Due Date), exclusive, however, in the case of an ARD Trust Mortgage
Loan after its Anticipated Repayment Date, of any such accrued and unpaid
interest that constitutes Additional Interest; third, as a recovery of principal
of such Trust Mortgage Loan then due and owing, including by reason of
acceleration of such Trust Mortgage Loan following a default thereunder (or, if
a Liquidation Event has occurred in respect of such Trust Mortgage Loan, as a
recovery of principal to the extent of its entire remaining unpaid principal
balance); fourth, unless a Liquidation Event has occurred with respect to such
Trust Mortgage Loan, as a recovery of amounts to be currently applied to the
payment of, or escrowed for the future payment of, real estate taxes,
assessments, insurance premiums (including premiums on any Environmental
Insurance Policy), ground rents (if applicable) and similar items; fifth, unless
a Liquidation Event has occurred with respect to such Trust Mortgage Loan, as a
recovery of Reserve Funds to the extent then required to be held in escrow;
sixth, as a recovery of any Prepayment Consideration then due and owing under
such Trust Mortgage Loan; seventh, as a recovery of any Default Charges then due
and owing under such Trust Mortgage Loan; eighth, as a recovery of any
assumption fees, modification fees and extension fees then due and owing under
such Trust Mortgage Loan; ninth, as a recovery of any other amounts then due and
owing under such Trust Mortgage Loan (other than remaining unpaid principal and,
in the case of an ARD Trust Mortgage Loan after its Anticipated Repayment Date,
other than Additional Interest); tenth, as a recovery of any remaining principal
of such Trust Mortgage Loan to the extent of its entire remaining unpaid
principal balance; and, eleventh, in the case of an ARD Trust Mortgage Loan
after its Anticipated Repayment Date, as a recovery of accrued and unpaid
Additional Interest on such ARD Trust Mortgage Loan to but not including the
date of receipt; provided that, if one or more Advances previously made in
respect of a Trust Mortgage Loan have been reimbursed out of general collections
of principal on the Mortgage Pool as one or more Nonrecoverable Advances, then
collections in respect of such Trust Mortgage Loan available for application
pursuant to clauses second through eleventh of this sentence shall instead be
applied in the following order--(i) as a recovery of accrued and unpaid interest
on, and principal of, such Trust Mortgage Loan, to the extent of any outstanding
P&I Advances and unpaid Master Servicing Fees in respect of such Trust Mortgage
Loan, (ii) as a recovery of the item(s) for which such previously reimbursed
Nonrecoverable Advance(s) were made (together with, but only if a Liquidation
Event has occurred with respect to such Trust Mortgage Loan, any interest on
such previously reimbursed Nonrecoverable Advance(s) that was also paid out of
general collections of principal on the Mortgage Pool), and (iii) in accordance
with clauses second through eleventh of this sentence (taking into account the
applications pursuant to clauses (i) and (ii) of this proviso).

          Subject to the last paragraph of this Section 3.02(b), all amounts
received with respect to any Serviced Loan Combination shall be applied to
amounts due and owing under the Mortgage Loans comprising such Loan Combination
(including for principal and accrued and unpaid interest) in accordance with the
express provisions of the related Mortgage Notes, the related Mortgage, the
related loan agreement, if any, and the related Co-Lender Agreement.

          Subject to the last paragraph of this Section 3.02(b), all amounts
Received by the Trust with respect to an Outside Serviced Trust Mortgage Loan
shall be allocated among interest, principal and/or prepayment consideration due
thereon in accordance with the terms of any distribution date statement or
servicer report received from the related Outside Servicers with respect to such
Outside Serviced Trust Mortgage Loan and, in the absence of any such statement
or report, in accordance with the related Co-Lender Agreement and, in the
absence of any allocation in the related Co-Lender Agreement, in accordance with
the first paragraph of this Section 3.02(b). Any nonrecoverable payment


                                      -153-



made by an Outside Servicer to cover interest shortfalls incurred with respect
to an Outside Serviced Trust Mortgage Loan by reason of a Principal Prepayment
or other early collection of principal being applied to such Outside Serviced
Trust Mortgage Loan prior to the related Due Date during the relevant Underlying
Collection Period, will be treated for purposes of this Agreement as if it was a
payment of interest by the related Mortgagor.

          Notwithstanding the foregoing, Loss of Value Payments shall not be
applied in accordance with the foregoing provisions of this Section 3.02(b)
unless and until such amounts are transferred to the Pool Custodial Account, and
deemed to constitute Liquidation Proceeds in respect of a particular Trust
Mortgage Loan, in accordance with Section 3.05(e); and Liquidation Proceeds
resulting from any purchase or repurchase out of the Trust Fund of, or any
application of Loss of Value Payments to, any Trust Mortgage Loan that is part
of a Loan Combination shall be applied in accordance with the provisions of the
first paragraph of this Section 3.02(b).

          (c) Promptly following the Closing Date, in the case of each Outside
Serviced Trust Mortgage Loan, the Trustee shall send written notice,
substantially in the form of Exhibit S hereto, to the related Outside Master
Servicer, stating that, as of the Closing Date, the Trustee is the holder of
such Outside Serviced Trust Mortgage Loan and directing the related Outside
Master Servicer to remit to the Master Servicer all amounts payable to, and to
forward, deliver or otherwise make available, as the case may be, to the Master
Servicer all reports, statements, documents, communications and other
information that are to be forwarded, delivered or otherwise made available to,
the holder of the subject Outside Serviced Trust Mortgage Loan under the related
Co-Lender Agreement and the related Outside Servicing Agreement. The Master
Servicer shall, within one (1) Business Day of receipt thereof, deposit into the
Pool Custodial Account all amounts received by it from any Outside Servicer or
any other party under the related Outside Servicing Agreement and/or the related
Co-Lender Agreement with respect to any Outside Serviced Trust Mortgage Loan,
the related Mortgaged Property or any related REO Property. In connection with
the foregoing, the Master Servicer shall provide each Outside Master Servicer
wiring instructions for remittances to the Master Servicer. In the event that,
during any calendar month, the Master Servicer fails to so receive any amounts,
including (if applicable) advances, due to the holder of an Outside Serviced
Trust Mortgage Loan under the related Co-Lender Agreement and/or the related
Outside Servicing Agreement by the end of the related Collection Period ending
in such calendar month, then the Master Servicer shall promptly (i) notify the
related Outside Master Servicer and any Outside Trustee under the related
Outside Servicing Agreement that such amounts due with respect to the subject
Outside Serviced Trust Mortgage Loan or any successor REO Trust Mortgage Loan
with respect thereto have not been received (specifying the amount of such
deficiency), (ii) make inquiry of the related Outside Master Servicer and any
Outside Trustee under the related Outside Servicing Agreement (and, to the
extent learned, inform the Trustee) as to the reason that such amounts have not
been timely received, (iii) as and to the extent appropriate, request that the
related Outside Master Servicer promptly remedy such failure to make a payment
or an advance, as the case may be, and (iv) make a P&I Advance with respect to
such amounts as and if required by the terms of this Agreement in accordance
with Section 4.03. Further, in accordance with Section 4.03, in the event the
Master Servicer fails to make such P&I Advance with respect to any Outside
Serviced Trust Mortgage Loan or any successor REO Trust Mortgage Loan with
respect thereto, then the Trustee or, if it fails to do so, any Fiscal Agent,
shall make such P&I Advance.


                                      -154-



          SECTION 3.03.  Collection of Taxes, Assessments and Similar Items;
                         Servicing Accounts; Reserve Accounts.

          (a) The Master Servicer shall, as to all Serviced Mortgage Loans,
establish and maintain one or more accounts (the "Servicing Accounts"), in which
all related Escrow Payments shall be deposited and retained; provided that, in
the case of a Serviced Loan Combination, if the related Servicing Account
includes funds with respect to any other Serviced Mortgage Loan, then the Master
Servicer shall maintain a separate sub-account of such Servicing Account that
relates solely to such Serviced Loan Combination. Subject to the terms of the
related loan documents, each Servicing Account shall be an Eligible Account.
Withdrawals of amounts so collected from a Servicing Account may be made (in
each case, to the extent of amounts on deposit therein in respect of the related
Serviced Mortgage Loan or, in the case of clauses (iv) and (v) below, to the
extent of interest or other income earned on such amounts) only for the
following purposes: (i) consistent with the related loan documents, to effect
the payment of real estate taxes, assessments, insurance premiums (including
premiums on any Environmental Insurance Policy), ground rents (if applicable)
and comparable items in respect of the respective Mortgaged Properties; (ii)
insofar as the particular Escrow Payment represents a late payment that was
intended to cover an item described in the immediately preceding clause (i) for
which a Servicing Advance was made, to reimburse the Master Servicer, the
Special Servicer, the Trustee or any Fiscal Agent, as applicable, for such
Servicing Advance; (iii) to refund to Mortgagors any sums as may be determined
to be overages; (iv) following an event of default under the related Serviced
Mortgage Loan, for such other purposes as are consistent with the related loan
documents, applicable law and the Servicing Standard; (v) to pay interest, if
required and as described below, to Mortgagors on balances in such Servicing
Account; (vi) to pay the Master Servicer interest and investment income on
balances in such Servicing Account as described in Section 3.06, if and to the
extent not required by law or the terms of the related loan documents to be paid
to the Mortgagor; or (vii) to clear and terminate such Servicing Account at the
termination of this Agreement in accordance with Section 9.01. To the extent
permitted by law or the applicable loan documents, funds in the Servicing
Accounts may be invested only in Permitted Investments in accordance with the
provisions of Section 3.06. The Master Servicer shall pay or cause to be paid to
the Mortgagors interest, if any, earned on the investment of funds in the
related Servicing Accounts, if required by law or the terms of the related
Serviced Mortgage Loan. If the Master Servicer shall deposit in a Servicing
Account any amount not required to be deposited therein, it may at any time
withdraw such amount from such Servicing Account, any provision herein to the
contrary notwithstanding.

          (b) The Master Servicer shall, as to each and every Serviced Mortgage
Loan, (i) maintain accurate records with respect to the related Mortgaged
Property reflecting the status of real estate taxes, assessments and other
similar items that are or may become a lien thereon and the status of insurance
premiums and any ground rents payable in respect thereof and (ii) use reasonable
efforts to obtain, from time to time, all bills for (or otherwise confirm) the
payment of such items (including renewal premiums) and, if the subject Serviced
Mortgage Loan requires the related Mortgagor to escrow for such items, shall
effect payment thereof prior to the applicable penalty or termination date. For
purposes of effecting any such payment for which it is responsible, the Master
Servicer shall apply Escrow Payments as allowed under the terms of the related
Serviced Mortgage Loan (or, if such Serviced Mortgage Loan does not require the
related Mortgagor to escrow for the payment of real estate taxes, assessments,
insurance premiums, ground rents (if applicable) and similar items, the Master
Servicer shall use reasonable efforts consistent with the Servicing Standard to
cause the related Mortgagor to comply with the requirement of the related
Mortgage that the Mortgagor make payments


                                      -155-



in respect of such items at the time they first become due and, in any event,
prior to the institution of foreclosure or similar proceedings with respect to
the related Mortgaged Property for nonpayment of such items). Subject to Section
3.11(h), the Master Servicer shall timely make a Servicing Advance to cover any
such item which is not so paid, including any penalties or other charges arising
from the Mortgagor's failure to timely pay such items.

          (c) The Master Servicer shall, as to each and every Serviced Mortgage
Loan, make a Servicing Advance with respect to the related Mortgaged Property in
an amount equal to all such funds as are necessary for the purpose of effecting
the payment of (i) real estate taxes, assessments and other similar items, (ii)
ground rents (if applicable), and (iii) premiums on Insurance Policies
(including Environmental Insurance Policies), in each instance if and to the
extent Escrow Payments (if any) collected from the related Mortgagor are
insufficient to pay such item when due and the related Mortgagor (or any related
guarantor or party entitled to exercise cure rights) has failed to pay such item
on a timely basis. All such Servicing Advances shall be reimbursable in the
first instance from related payments by or on behalf of the Mortgagors, and
further as provided in Section 3.05(a) and/or Section 3.05A. No costs incurred
by the Master Servicer in effecting the payment of real estate taxes,
assessments and, if applicable, ground rents on or in respect of the Mortgaged
Properties shall, for purposes of this Agreement, including the Trustee's
calculation of monthly distributions to Certificateholders, be added to the
unpaid Stated Principal Balances of the related Serviced Mortgage Loans,
notwithstanding that the terms of such Mortgage Loans so permit. The foregoing
shall in no way limit the Master Servicer's ability to charge and collect from
the Mortgagor such costs together with interest thereon.

          (d) The Master Servicer shall, as to all Serviced Mortgage Loans,
establish and maintain, as applicable, one or more accounts (the "Reserve
Accounts"), into which all related Reserve Funds, if any, shall be deposited and
retained; provided that, in the case of a Serviced Loan Combination, if the
related Reserve Account includes funds with respect to any other Mortgage Loan,
then the Master Servicer shall maintain a separate sub-account of such Reserve
Account that relates solely to such Serviced Loan Combination. Withdrawals of
amounts so deposited may be made (i) for the specific purposes for which the
particular Reserve Funds were delivered, in accordance with the Servicing
Standard and the terms of the related Mortgage Note, Mortgage and any other
agreement with the related Mortgagor governing such Reserve Funds, (ii) to pay
the Master Servicer interest and investment income earned on amounts in the
Reserve Accounts as described below, and (iii) following an event of default
under the related Serviced Mortgage Loan, for such other purposes as are
consistent with the related loan documents, applicable law and the Servicing
Standard. To the extent permitted in the applicable loan documents, funds in the
Reserve Accounts may be invested in Permitted Investments in accordance with the
provisions of Section 3.06. Subject to the related loan documents, all Reserve
Accounts shall be Eligible Accounts. Consistent with the Servicing Standard, the
Master Servicer may waive or extend the date set forth in any agreement
governing Reserve Funds by which any required repairs, capital improvements
and/or environmental remediation at the related Mortgaged Property must be
completed; provided that any waiver, any extension for more than 120 days and
any subsequent extension may only be granted with the consent of the Special
Servicer.


                                      -156-



          SECTION 3.04.  Pool Custodial Account, Defeasance Deposit Account,
                         Collection Account, Interest Reserve Account, Excess
                         Liquidation Proceeds Account and Loss of Value Reserve
                         Fund.

          (a) The Master Servicer shall establish and maintain one or more
separate, segregated accounts (collectively, the "Pool Custodial Account"), in
which the amounts described in clauses (i) through (xi) below (which shall not
include any amounts allocable to the Non-Trust Mortgage Loans) shall be
deposited and held on behalf of the Trustee in trust for the sole benefit of the
Certificateholders. The Pool Custodial Account shall be an Eligible Account. The
Master Servicer shall deposit or cause to be deposited in the Pool Custodial
Account, within one (1) Business Day of receipt (in the case of payments by
Mortgagors or other collections on the Trust Mortgage Loans) or as otherwise
required hereunder, the following payments and collections received (including
amounts Received by the Trust with respect to the Outside Serviced Trust
Mortgage Loans and/or any successor REO Trust Mortgage Loans with respect
thereto) or made by the Master Servicer or on its behalf subsequent to the
Cut-off Date (other than in respect of principal and interest on the Trust
Mortgage Loans due and payable on or before the Cut-off Date, which amounts
shall be delivered promptly to the Depositor or its designee, with negotiable
instruments endorsed as necessary and appropriate without recourse, and other
than amounts required to be deposited in the Defeasance Deposit Account), or any
of the following payments (other than Principal Prepayments) received by it on
or prior to the Cut-off Date but allocable to a period subsequent thereto:

               (i) all payments on account of principal of the Serviced Trust
     Mortgage Loans, including Principal Prepayments, and regardless of whether
     those payments are made by the related Mortgagor, any related guarantor or
     any party exercising cure rights hereunder or under any related co-lender,
     intercreditor or similar agreement, out of any related Reserve Funds
     maintained for such purpose, out of collections on any related Defeasance
     Collateral or from any other source;

               (ii) all payments on account of interest on the Serviced Trust
     Mortgage Loans, including Default Interest and Additional Interest, and
     regardless of whether those payments are made by the related Mortgagor, any
     related guarantor or any party exercising cure rights hereunder or under
     any related co-lender, intercreditor or similar agreement, out of any
     related Reserve Funds maintained for such purpose, out of collections on
     any related Defeasance Collateral or from any other source;

               (iii) all Prepayment Consideration and late payment charges
     Received by the Trust in respect of any Trust Mortgage Loan;

               (iv) all Insurance Proceeds, Condemnation Proceeds and
     Liquidation Proceeds Received by the Trust in respect of any Trust Mortgage
     Loan or, except to the extent such proceeds are to first be deposited in an
     REO Account, any REO Property;

               (v) any amounts representing a reimbursement, payment and/or
     contribution due and owing to the Trust from any Non-Trust Mortgage Loan
     Noteholder in accordance with the related Co-Lender Agreement;

               (vi) all remittances, including (if applicable) advances, to the
     Trust under the related Outside Servicing Agreement and/or the related
     Co-Lender Agreement with respect to


                                      -157-



     each Outside Serviced Trust Mortgage Loan or any successor REO Trust
     Mortgage Loan with respect thereto;

               (vii) any amounts required to be deposited by the Master Servicer
     pursuant to Section 3.06 in connection with losses incurred with respect to
     Permitted Investments of funds held in the Pool Custodial Account;

               (viii) any amounts required to be deposited by the Master

     with losses on the Mortgage Pool resulting from a deductible clause in a
     blanket or master force placed hazard insurance policy;

               (ix) any amounts required to be transferred from the Loss of
     Value Reserve Fund pursuant to Section 3.05(e), any Loan Combination
     Custodial Account pursuant to Section 3.05A or the Pool REO Account
     pursuant to Section 3.16(c);

               (x) insofar as they do not constitute Escrow Payments, any
     amounts paid by a Mortgagor with respect to a Serviced Trust Mortgage Loan
     specifically to cover items for which a Servicing Advance has been made;
     and

               (xi) the Initial Deposits, if any;

provided that any amounts described in clauses (i) through (iv), (viii) and (x)
above that relate to a Serviced Combination Trust Mortgage Loan or any successor
REO Trust Mortgage Loan with respect thereto (other than Liquidation Proceeds
derived from the Permitted Purchase of such Trust Mortgage Loan or the Trust's
interest in any related REO Property) shall be deposited in the applicable Loan
Combination Custodial Account, and, in any such case, shall thereafter be
transferred to the Pool Custodial Account as provided in Section 3.05A, together
with any other amounts required to be transferred from such Loan Combination
Custodial Account to the Pool Custodial Account from time to time pursuant to
Section 3.05A.

          The foregoing requirements for deposit in the Pool Custodial Account
shall be exclusive. Notwithstanding the foregoing, actual payments from
Mortgagors in the nature of Escrow Payments, Reserve Funds, assumption fees,
assumption application fees, funds representing a Mortgagor's payment of costs
and expenses associated with assumptions and defeasance, modification fees,
extension fees, charges for beneficiary statements or demands, amounts collected
for checks returned for insufficient funds and any similar fees (other than
Prepayment Consideration) not expressly referred to in the prior paragraph need
not be deposited by the Master Servicer in the Pool Custodial Account. If the
Master Servicer shall deposit in the Pool Custodial Account any amount not
required to be deposited therein, it may at any time withdraw such amount from
the Pool Custodial Account, any provision herein to the contrary
notwithstanding. The Master Servicer shall promptly deliver to the Special
Servicer, as additional special servicing compensation in accordance with
Section 3.11(d), all assumption fees and assumption application fees (or the
applicable portions thereof), and other transaction fees received by the Master
Servicer to which the Special Servicer is entitled pursuant to such section upon
receipt of a written statement (on which the Master Servicer is entitled to
rely) of a Servicing Officer of the Special Servicer describing the item and
amount (unless pursuant to this Agreement it is otherwise clear that the Special
Servicer is entitled to such amounts, in which case a written statement is not
required). The Pool Custodial Account shall be maintained as a segregated
account, separate and apart from trust funds created for mortgage-backed
securities of other series and the other accounts of the Master Servicer.


                                      -158-



          Upon receipt of any of the amounts described in clauses (i) through
(v) and (x) of the second preceding paragraph with respect to any Serviced Trust
Mortgage Loan, the Special Servicer shall promptly, but in no event later than
two (2) Business Days after receipt, remit such amounts to the Master Servicer

preceding paragraph (or, if applicable, in the case of a Serviced Combination
Trust Mortgage Loan, into the applicable Loan Combination Custodial Account in
accordance with Section 3.04A(a) and the proviso to the second preceding
paragraph), unless the Special Servicer determines, consistent with the
Servicing Standard, that a particular item should not be deposited because of a
restrictive endorsement or other appropriate reason. With respect to any such
amounts paid by check to the order of the Special Servicer, the Special Servicer
shall endorse such check to the order of the Master Servicer, unless the Special
Servicer determines, consistent with the Servicing Standard, that a particular
item cannot be so endorsed and delivered because of a restrictive endorsement or
other appropriate reason. Any such amounts received by the Special Servicer with
respect to an Administered REO Property (other than an Administered REO Property
that relates to a Serviced Loan Combination) shall be deposited by the Special
Servicer into the Pool REO Account and thereafter remitted to the Master
Servicer for deposit into the Pool Custodial Account as and to the extent
provided in Section 3.16(c).

          If and when any Mortgagor under any Defeasance Mortgage Loan that is
also a Serviced Mortgage Loan elects to defease all or any part of its Serviced
Mortgage Loan and, pursuant to the provisions of the related loan documents,
delivers cash to the Master Servicer to purchase the required Defeasance
Collateral, the Master Servicer shall establish and maintain one or more
separate segregated accounts (collectively, the "Defeasance Deposit Account"),
in which the Master Servicer shall deposit such cash within one (1) Business Day
of receipt by the Master Servicer. The Master Servicer shall retain such cash in
the Defeasance Deposit Account pending its prompt application to purchase
Defeasance Collateral. The Master Servicer shall hold such cash and maintain the
Defeasance Deposit Account on behalf of the Trustee and, in the case of a
Serviced Loan Combination, the related Serviced Non-Trust Mortgage Loan
Noteholder(s), to secure payment on the related Defeasance Mortgage Loan. The
Defeasance Deposit Account shall be an Eligible Account. To the extent permitted
by law or the applicable Defeasance Mortgage Loan, prior to the purchase of
Defeasance Collateral, funds in the Defeasance Deposit Account may be invested
only in Permitted Investments in accordance with the provisions of Section 3.06.
The Master Servicer shall pay or cause to be paid to the related Mortgagor(s)
interest, if any, earned on the investment of funds in the Defeasance Deposit
Account, if required by law or the terms of the related Defeasance Mortgage
Loan(s).

          Notwithstanding the foregoing, in the event that the Master Servicer
receives cash to purchase Defeasance Collateral for any Early Defeasance Trust
Mortgage Loan that the Depositor or the UBS Mortgage Loan Seller, as applicable,
is required to repurchase pursuant to or as otherwise contemplated by Section
2.03(j), the Master Servicer shall retain such cash in the Defeasance Deposit
Account on behalf of the Trust Fund until the Depositor or the UBS Mortgage Loan
Seller, as applicable, tenders the full Purchase Price in connection with such
repurchase and shall, on the date of such repurchase, transfer such cash to the
Depositor or the UBS Mortgage Loan Seller, as applicable.

          (b) The Trustee shall establish and maintain one or more separate,
segregated trust accounts (collectively, the "Collection Account") to be held in
trust for the sole benefit of the Certificateholders. Each account that
constitutes the Collection Account shall be an Eligible Account. Subject to
Section 2.05(b), the Trustee shall establish and maintain, on a book-entry
basis, the "Class V Sub-Account", which sub-account shall be deemed to be held
in trust for the benefit of the Holders of the


                                      -159-



Class V Certificates. The Master Servicer shall deliver to the Trustee each
month on or before the Trust Master Servicer Remittance Date therein, for
deposit in the Collection Account, an aggregate amount of immediately available
funds equal to the Master Servicer Remittance Amount for such Trust Master
Servicer Remittance Date, together with, in the case of the Final Distribution
Date, any additional amounts contemplated by Section 9.01 and any Loss of Value
Payments contemplated by Section 3.05(e). Immediately upon deposit of the Master
Servicer Remittance Amount for any Trust Master Servicer Remittance Date into
the Collection Account, subject to Section 2.05(b), any portion thereof that
represents Additional Interest shall be deemed to have been deposited into the
Class V Sub-Account.

          In addition, the Master Servicer shall, as and when required
hereunder, deliver to the Trustee (without duplication) for deposit in the
Collection Account:

               (i) any P&I Advances required to be made by the Master Servicer
     in accordance with Section 4.03(a); and

               (ii) any amounts required to be deposited by the Master Servicer
     pursuant to Section 3.19(a) in connection with Prepayment Interest
     Shortfalls.

          The Trustee shall, upon receipt, deposit in the Collection Account any
and all amounts received by it that are required by the terms of this Agreement
to be deposited therein. In addition, as and when required pursuant to Section
3.06, the Trustee shall (in all cases prior to distributions on the Certificates
being made on the related Distribution Date) deposit in the Collection Account
any amounts required to be so deposited by the Trustee pursuant to Section 3.06
in connection with losses incurred with respect to Permitted Investments of
funds held in the Collection Account.

          In the event that the Master Servicer fails, on any Trust Master
Servicer Remittance Date, to remit to the Trustee any amount(s) required to be
so remitted to the Trustee hereunder by such date, the Master Servicer shall pay
the Trustee, for the account of the Trustee, interest, calculated at the Prime
Rate, on such amount(s) not timely remitted, from and including that Trust
Master Servicer Remittance Date, to but not including the related Distribution
Date.

          On the Trust Master Servicer Remittance Date in March of each year
(commencing in March 2007), the Trustee shall transfer from the Interest Reserve
Account to the Collection Account all Interest Reserve Amounts then on deposit
in the Interest Reserve Account with respect to the Interest Reserve Mortgage
Loans and any Interest Reserve REO Mortgage Loans.

          As and when required pursuant to Section 3.05(d), the Trustee shall
transfer monies from the Excess Liquidation Proceeds Account to the Collection
Account.

          (c) The Trustee shall establish and maintain one or more separate,
segregated accounts (collectively, the "Interest Reserve Account"), to be held
in trust for the sole benefit of the Certificateholders, for purposes of holding
the Interest Reserve Amounts in respect of the Interest Reserve Mortgage Loans
and any Interest Reserve REO Mortgage Loans. Each account that constitutes the
Interest Reserve Account shall be an Eligible Account. As and when received from
the Mortgage Loan Sellers, the Trustee shall deposit in the Interest Reserve
Account all Supplemental Interest Reserve Amounts with respect to the Interest
Reserve Mortgage Loans. In addition, on each Distribution Date in February and,
during a year that is not a leap year, in January, commencing in January 2007,
prior to any


                                      -160-



distributions being made in respect of the Certificates on the subject
Distribution Date, the Trustee shall withdraw from the Collection Account and
deposit in the Interest Reserve Account with respect to each Interest Reserve
Mortgage Loan and Interest Reserve REO Mortgage Loan, an amount equal to the
Interest Reserve Amount, if any, in respect of such Mortgage Loan or REO
Mortgage Loan, as the case may be, for such Distribution Date; provided that no
such transfer of funds shall occur if the subject Distribution Date is the Final
Distribution Date. Furthermore, as and when required pursuant to Section 3.06,
the Trustee shall (in any event prior to any distributions on the Certificates
and any transfers to the Collection Account on or before the related
Distribution Date) deposit in the Interest Reserve Account any amounts required
to be so deposited by the Trustee pursuant to Section 3.06 in connection with
losses incurred with respect to Permitted Investments of funds held in the
Interest Reserve Account. Subject to the next paragraph, the Interest Reserve
Account may be a sub-account of the Collection Account.

          Notwithstanding that the Interest Reserve Account may be a sub-account
of the Collection Account for reasons of administrative convenience, the
Interest Reserve Account and the Collection Account shall, for all purposes of
this Agreement (including the obligations and responsibilities of the Trustee
hereunder), be considered to be and shall be required to be treated as, separate
and distinct accounts. The Trustee shall indemnify and hold harmless the Trust
Fund against any losses arising out of the failure by the Trustee to perform its
duties and obligations hereunder as if such accounts were separate accounts. The
provisions of this paragraph shall survive any resignation or removal of the
Trustee and appointment of a successor trustee.

          (d) If any Excess Liquidation Proceeds are received on the Mortgage
Pool, the Trustee shall establish and maintain one or more separate, segregated
accounts (collectively, the "Excess Liquidation Proceeds Account") to be held in
trust for the sole benefit of the Certificateholders, for purposes of holding
such Excess Liquidation Proceeds. Each account that constitutes the Excess
Liquidation Proceeds Account shall be an Eligible Account. On each Trust Master
Servicer Remittance Date, the Master Servicer shall withdraw from the Pool
Custodial Account and remit to the Trustee for deposit in the Excess Liquidation
Proceeds Account all Excess Liquidation Proceeds received with respect to the
Mortgage Pool during the related Collection Period ending in the calendar month
in which such Trust Master Servicer Remittance Date occurs. In addition, as and
when required pursuant to Section 3.06, the Trustee shall (in any event prior to
any transfers to the Collection Account on or before the related Distribution
Date) deposit in the Excess Liquidation Proceeds Account any amounts required to
be so deposited by the Trustee pursuant to Section 3.06 in connection with
losses incurred with respect to Permitted Investments of funds held in the
Excess Liquidation Proceeds Account. Subject to the next paragraph, the Excess
Liquidation Proceeds Account may be a sub-account of the Collection Account.

          Notwithstanding that the Excess Liquidation Proceeds Account may be a
sub-account of the Collection Account for reasons of administrative convenience,
the Excess Liquidation Proceeds Account and the Collection Account shall, for
all purposes of this Agreement (including the obligations and responsibilities
of the Trustee hereunder), be considered to be and shall be required to be
treated as, separate and distinct accounts. The Trustee shall indemnify and hold
harmless the Trust Fund against any losses arising out of the failure by the
Trustee to perform its duties and obligations hereunder as if such accounts were
separate accounts. The provisions of this paragraph shall survive any
resignation or removal of the Trustee and appointment of a successor trustee.


                                      -161-



          (e) If any Loss of Value Payments are received in connection with a
Material Document Defect or Material Breach, as the case may be, pursuant to or
as contemplated by Section 2.03(e), the Special Servicer shall establish and
maintain one or more non-interest bearing separate, segregated accounts
(collectively, the "Loss of Value Reserve Fund") to be held in trust for the
sole benefit of the Certificateholders, for purposes of holding such Loss of
Value Payments. Each account that constitutes the Loss of Value Reserve Fund
shall be an Eligible Account. The Special Servicer shall, upon receipt, deposit
in the Loss of Value Reserve Fund all Loss of Value Payments received by it.

          (f) Funds (other than the Initial Deposits) in the Pool Custodial
Account, the Collection Account, the Interest Reserve Account and the Excess
Liquidation Proceeds Account may be invested only in Permitted Investments in
accordance with the provisions of Section 3.06. Funds in the Loss of Value
Reserve Fund shall remain uninvested. The Master Servicer shall give notice to
the Trustee, the Special Servicer and the Rating Agencies of the location of the
Pool Custodial Account as of the Closing Date and of the new location of the
Pool Custodial Account prior to any change thereof. As of the Closing Date, the
Collection Account, the Interest Reserve Account and the Excess Liquidation
Proceeds Account shall be located at the Trustee's Corporate Trust Office. The
Trustee shall give notice to the Master Servicer, the Special Servicer and the
Rating Agencies of any change in the location of the Collection Account, the
Interest Reserve Account or the Excess Liquidation Proceeds Account prior to any
change thereof.

          SECTION 3.04A. Loan Combination Custodial Accounts for Serviced Loan
                         Combinations.

          (a) With respect to each Serviced Loan Combination, the Master
Servicer shall establish and maintain one or more separate, segregated accounts
(collectively, with respect to such Serviced Loan Combination, the related "Loan
Combination Custodial Account") in which the amounts described in clauses (i)
through (ix) below, insofar as they are related to one or more Mortgage Loans
included in such Serviced Loan Combination, shall be deposited and held in trust
for the sole benefit of the holders of such Mortgage Loans, as their interests
may appear; provided that, subject to the last paragraph of this Section
3.04A(a), each Loan Combination Custodial Account may be a sub-account of the
Pool Custodial Account. Each Loan Combination Custodial Account shall be an
Eligible Account or, subject to the last paragraph of this Section 3.04A(a), a
sub-account of an Eligible Account. The Master Servicer shall deposit or cause
to be deposited in each Loan Combination Custodial Account, within one (1)
Business Day of receipt (in the case of payments or other collections on the
related Serviced Loan Combination) or as otherwise required hereunder, the
following payments and collections received or made by the Master Servicer or on
its behalf with respect to the related Serviced Loan Combination subsequent to
the Cut-off Date (other than in respect of principal and interest on such
Serviced Loan Combination due and payable on or before the Cut-off Date, which
payments shall be held pursuant to the terms of the related Co-Lender Agreement,
and other than amounts required to be deposited in the Defeasance Deposit
Account):

               (i) all payments on account of principal of the related Serviced
     Loan Combination, including Principal Prepayments, and regardless of
     whether those payments are made by the related Mortgagor, any related
     guarantor or any party exercising any cure rights hereunder or under the
     related Co-Lender Agreement or any related mezzanine intercreditor


                                      -162-



     agreement, out of any related Reserve Funds maintained for such purpose,
     out of collections on any related Defeasance Collateral or from any other
     source;

               (ii) all payments on account of interest on the related Serviced
     Loan Combination, including Default Interest, and regardless of whether
     those payments are made by the related Mortgagor, any related guarantor, or
     any party exercising any cure rights hereunder or under the related
     Co-Lender Agreement or any related mezzanine intercreditor agreement, out
     of any related Reserve Funds maintained for such purpose, out of
     collections on any related Defeasance Collateral or from any other source;

               (iii) all Prepayment Consideration and/or late payment charges
     received in respect of the related Serviced Loan Combination;

               (iv) all Insurance Proceeds, Condemnation Proceeds and
     Liquidation Proceeds received in respect of the related Serviced Loan
     Combination or, except to the extent such proceeds are to first be
     deposited in a Loan Combination REO Account, any related Administered REO
     Property;

               (v) any amounts required to be deposited by the Master Servicer
     pursuant to Section 3.06 in connection with losses incurred with respect to
     Permitted Investments of funds held in such Loan Combination Custodial
     Account;

               (vi) any amounts required to be deposited by the Master Servicer
     or the Special Servicer pursuant to Section 3.07(b) in connection with
     losses with respect to the related Serviced Loan Combination resulting from
     a deductible clause in a blanket or master force placed hazard insurance
     policy;

               (vii) any amounts required to be transferred from the Loan
     Combination REO Account established with respect to the related Serviced
     Loan Combination pursuant to Section 3.16(c);

               (viii) insofar as they do not constitute Escrow Payments, any
     amounts paid by the related Mortgagor with respect to the related Serviced
     Loan Combination specifically to cover items for which a Servicing Advance
     has been made; and

               (ix) any amounts representing a reimbursement, payment and/or
     contribution due and owing to a party other than the Trust from any related
     Non-Trust Mortgage Loan Noteholder in accordance with the related Co-Lender
     Agreement;

provided that, with respect to a Serviced Loan Combination, any Liquidation
Proceeds derived from a Permitted Purchase of the Trust Mortgage Loan included
in such Serviced Loan Combination or the Trust's interest in any related REO
Property, shall in each case be deposited into the Pool Custodial Account.

          The foregoing requirements for deposit in each Loan Combination
Custodial Account shall be exclusive. Notwithstanding the foregoing, actual
payments from the related Mortgagor in respect of the related Serviced Loan
Combination in the nature of Escrow Payments, Reserve Funds, assumption fees,
assumption application fees, funds representing such Mortgagor's payment of
costs and


                                      -163-



expenses associated with assumptions and defeasance, modification fees,
extension fees, charges for beneficiary statements or demands, amounts collected
for checks returned for insufficient funds and any similar fees to which the
Master Servicer or Special Servicer is entitled as additional servicing
compensation and that are not expressly referred to in the prior paragraph, need
not be deposited by the Master Servicer in the subject Loan Combination
Custodial Account. If the Master Servicer shall deposit into any Loan
Combination Custodial Account any amount not required to be deposited therein,
then it may at any time withdraw such amount from such Custodial Account, any
provision herein to the contrary notwithstanding. The Master Servicer shall
promptly deliver to the Special Servicer, as additional special servicing
compensation in accordance with Section 3.11(d), all assumption fees and
assumption application fees (or the applicable portions thereof) and other
transaction fees received by the Master Servicer with respect to each Serviced
Loan Combination, to which the Special Servicer is entitled pursuant to such
section, upon receipt of a written statement of a Servicing Officer of the
Special Servicer describing the item and amount (unless pursuant to this
Agreement it is otherwise clear that the Special Servicer is entitled to such
amounts, in which case a written statement is not required). Each Loan
Combination Custodial Account shall be maintained as a segregated account,
separate and apart from trust funds created for mortgage-backed securities of
other series and the other accounts of the Master Servicer.

          Upon receipt of any of the amounts described in clauses (i) through
(iv), (viii) and (ix) of the second preceding paragraph with respect to any
Serviced Loan Combination, the Special Servicer shall promptly, but in no event
later than two (2) Business Days after receipt, remit such amounts to the Master
Servicer for deposit into the related Loan Combination Custodial Account in
accordance with the second preceding paragraph (or, if applicable, into the Pool
Custodial Account in accordance with Section 3.04(a) and the proviso to the
second preceding paragraph), unless the Special Servicer determines, consistent
with the Servicing Standard, that a particular item should not be deposited
because of a restrictive endorsement or other appropriate reason. With respect
to any such amounts paid by check to the order of the Special Servicer, the
Special Servicer shall endorse such check to the order of the Master Servicer,
unless the Special Servicer determines, consistent with the Servicing Standard,
that a particular item cannot be so endorsed and delivered because of a
restrictive endorsement or other appropriate reason. Any such amounts received
by the Special Servicer with respect to an Administered REO Property that
relates to a Serviced Loan Combination shall initially be deposited by the
Special Servicer into the Loan Combination REO Account established with respect
to such Serviced Loan Combination and thereafter remitted to the Master Servicer
for deposit into the related Loan Combination Custodial Account, all in
accordance with Section 3.16(c).

          Notwithstanding that a Loan Combination Custodial Account may be a
sub-account of the Pool Custodial Account for reasons of administrative
convenience, such Loan Combination Custodial Account and the Pool Custodial
Account shall, for all purposes of this Agreement (including the obligations and
responsibilities of the Master Servicer hereunder), be considered to be and
shall be required to be treated as, separate and distinct accounts. The Master
Servicer shall indemnify and hold harmless the Trust Fund and the respective
related Non-Trust Mortgage Loan Noteholders against any losses arising out of
the failure by the Master Servicer to perform its duties and obligations
hereunder as if such accounts were separate accounts. The provisions of this
paragraph shall survive any resignation or removal of the Master Servicer and
appointment of a successor master servicer.


                                      -164-



          (b) If and when the related Mortgagor elects to defease any Serviced
Loan Combination or any portion thereof, the provisions of the next to last
paragraph of Section 3.04(a) relating to the Defeasance Deposit Account shall
apply.

          (c) In connection with each Serviced Loan Combination, the Master
Servicer shall give notice to the Trustee, the related Non-Trust Mortgage Loan
Noteholder(s) and the Special Servicer of the location of the related Loan
Combination Custodial Account when first established and of the new location of
the related Loan Combination Custodial Account prior to any change thereof.

          SECTION 3.05.  Permitted Withdrawals From the Pool Custodial Account,
                         the Collection Account, the Interest Reserve Account
                         and the Excess Liquidation Proceeds Account.

          (a) Subject to Section 1.03(e), which limits the application of
amounts otherwise distributable with respect to the Loan-Specific Certificates,
the Master Servicer may, from time to time, make withdrawals from the Pool
Custodial Account for any of the following purposes (the order set forth below
not constituting an order of priority for such withdrawals):

     the amounts required to be so deposited pursuant to the first paragraph of
     Section 3.04(b), and any amounts that may be applied to make P&I Advances

               (ii) to reimburse any Fiscal Agent, the Trustee and itself, in
     that order, for unreimbursed P&I Advances made thereby with respect to the

     any successor REO Trust Mortgage Loan with respect thereto), such Fiscal
     Agent's, the Trustee's and the Master Servicer's, as the case may be,
     respective rights to reimbursement pursuant to this clause (ii) with
     respect to any such P&I Advance being limited to amounts on deposit in the
     Pool Custodial Account that represent Late Collections of interest and
     principal (net of related Master Servicing Fees and any related Workout
     Fees and/or Liquidation Fees) received in respect of the particular Trust
     Mortgage Loan or REO Trust Mortgage Loan as to which such P&I Advance was
     made;

               (iii) to pay to itself earned and unpaid Master Servicing Fees
     with respect to the Mortgage Pool (exclusive of any Serviced Combination
     Trust Mortgage Loan or any successor REO Trust Mortgage Loan with respect
     thereto), the Master Servicer's right to payment pursuant to this clause
     (iii) with respect to any such Master Servicing Fees being limited to
     amounts on deposit in the Pool Custodial Account that are allocable as a
     recovery of interest on or in respect of the Trust Mortgage Loan or REO
     Trust Mortgage Loan as to which such Master Servicing Fees were earned;

               (iv) to pay (A) to the Special Servicer, out of general

     above or Section 3.05A, as applicable, following a Final Recovery


                                      -165-



     Determination made with respect to such Trust Mortgage Loan or the related
     REO Property and the deposit into the Pool Custodial Account of all amounts
     received in connection with such Final Recovery Determination;

               (v) to pay the Special Servicer (or, if applicable, a predecessor
     Special Servicer) any earned and unpaid Workout Fees and Liquidation Fees
     in respect of each Specially Serviced Trust Mortgage Loan, each Corrected

     Administered REO Property (other than, if applicable, any Serviced
     Combination Trust Mortgage Loan or any successor REO Trust Mortgage Loan
     with respect thereto), as applicable, in the amounts and from the sources
     specified in Section 3.11(c);

               (vi) to reimburse any Fiscal Agent, the Trustee, itself and the
     Special Servicer, in that order, for any unreimbursed Servicing Advances

     respective rights to reimbursement pursuant to this clause (vi) with
     respect to any Servicing Advance being limited to amounts on deposit in the
     Pool Custodial Account that represent payments made by or on behalf of the
     related Mortgagor to cover the item for which such Servicing Advance was
     made, and to amounts on deposit in the Pool Custodial Account that
     represent Liquidation Proceeds, Condemnation Proceeds, Insurance Proceeds
     and, if applicable, REO Revenues (in each case, if applicable, net of any

     the particular Serviced Trust Mortgage Loan or Administered REO Property as
     to which such Servicing Advance was made;

               (vii) to reimburse any Fiscal Agent, the Trustee, itself and the
     Special Servicer, in that order, out of general collections on the Mortgage

     (provided that such amounts may be withdrawn over time in accordance with
     Sections 3.11(g) or 4.03(d), as applicable);

               (viii) to pay any Fiscal Agent, the Trustee, itself and the
     Special Servicer, in that order, any unpaid interest accrued and payable in
     accordance with Section 3.11(g) or 4.03(d), as applicable, on any Advance
     made thereby under this Agreement, such Fiscal Agent's, the Trustee's, the
     Master Servicer's and the Special Servicer's respective rights to payment
     pursuant to this clause (viii) with respect to interest on any such Advance
     being limited to amounts on deposit in the Pool Custodial Account that

     Advance was made, as and to the extent contemplated by Section 3.26;

     on any Advance made thereby with respect to the Mortgage Pool (or, in the
     case of a Servicing Advance, made thereby with respect to a Serviced Loan
     Combination), but only to the extent that such Advance has been reimbursed
     or is then being reimbursed and the related Default Charges then on deposit
     in the Pool Custodial Account are not sufficient to make such


                                      -166-



     payment as contemplated by the immediately preceding clause (viii);
     provided that, if such Advance relates to any Serviced Combination Trust
     Mortgage Loan or any successor REO Trust Mortgage Loan with respect thereto
     (or, in the case of Servicing Advance, relates to any Serviced Loan
     Combination), such payment pursuant to this clause (ix) is to be made only
     to the extent that the funds on deposit in the related Loan Combination
     Custodial Account are not sufficient to make such payment as contemplated
     by Section 3.05A and such payment cannot be made out of the Pool Custodial
     Account pursuant to clause (xviii) of this Section 3.05(a);

               (x) to pay, out of amounts on deposit in the Pool Custodial
     Account that represent Default Charges collected on or in respect of the
     Trust Mortgage Loan or REO Trust Mortgage Loan to which the subject expense

               (xix) in the event the Master Servicer determines, in accordance
     with the Servicing Standard, with respect to an Outside Serviced Trust
     Mortgage Loan, that it has received insufficient information from the
     Outside Master Servicer to make a recoverability determination with respect
     to required P&I Advances on that Outside Serviced Trust Mortgage Loan, to
     pay, out of general collections on the Mortgage Pool on deposit in the Pool
     Custodial Account, for costs incurred in connection with obtaining an

withdrawal from the Pool Custodial Account pursuant to clauses (ii) through
(xx) above.

          The Master Servicer shall pay to the Special Servicer (or to
third-party contractors at the direction of the Special Servicer), the Trustee
or any Fiscal Agent from the Pool Custodial Account, amounts permitted to be
paid to the Special Servicer (or to any such third-party contractor), the
Trustee or such Fiscal Agent therefrom promptly upon receipt of a written
statement of a Servicing Officer of the Special Servicer or of a Responsible
Officer of the Trustee or such Fiscal Agent describing the item and amount to
which the Special Servicer (or such third-party contractor), the Trustee or such
Fiscal Agent, as applicable, is entitled (unless such payment to the Special
Servicer, the Trustee (for example, the Trustee Fee) or such Fiscal Agent, as
the case may be, is clearly required pursuant to this Agreement, in which case a
written statement is not required). The Master Servicer may rely conclusively on
any such written statement and shall have no duty to re-calculate the amounts
stated therein.


                                      -169-



          In connection with any payments required to be made to a Non-Trust
Mortgage Loan Noteholder or an Outside Servicer in accordance with Section

authorized officer of such Non-Trust Mortgage Loan Noteholder or Outside
Servicer, as the case may be, describing the nature and amount of the item for
which such party is seeking payment or reimbursement and setting forth the
provision(s) of the related Co-Lender Agreement pursuant to which such party
believes it is entitled to reimbursement; provided that the Master Servicer may
not condition payments required to be made to a Non-Trust Mortgage Loan
Noteholder or an Outside Servicer in accordance with Section 3.05(a)(xvii) upon
receipt of such a written statement (other than as permitted under the related
Co-Lender Agreement); and provided, further, that to the extent such a written
statement from an officer of the subject Non-Trust Mortgage Loan Noteholder or
Outside Servicer, as the case may be, is received by the Master Servicer, the
Master Servicer may reasonably rely upon such statement as the nature and amount
of the item for which reimbursement is sought.

          The Special Servicer shall keep and maintain separate accounting for
each Specially Serviced Trust Mortgage Loan and Administered REO Property, on a
loan-by-loan basis, for the purpose of justifying any request for withdrawal
from the Pool Custodial Account. With respect to each Trust Mortgage Loan for
which it makes an Advance, each of the Trustee and any Fiscal Agent shall keep
and maintain separate accounting, on a loan-by-loan basis, for the purpose of
justifying any request for withdrawal from the Pool Custodial Account for
reimbursements of Advances or payments of interest thereon.

          (b) Subject to Section 1.03(e), which limits the application of
amounts otherwise distributable with respect to the Loan-Specific Certificates,

     transferring Mortgage Files and other documents to a successor after being
     terminated by Certificateholders pursuant to Section 8.07(c) without cause;

               (iii) to pay, out of general collections on the Mortgage Pool on

     Section 10.01(j) or Section 10.02(f);

               (v) to pay the Tax Administrator, out of general collections on
     the Mortgage Pool on deposit in the Collection Account, any amounts
     reimbursable to it pursuant to Section 10.01(f) or Section 10.02(b);

               (vi) to pay the Master Servicer any amounts deposited by the
     Master Servicer in the Collection Account in error;

               (vii) to transfer Interest Reserve Amounts in respect of the
     Interest Reserve Mortgage Loans and any Interest Reserve REO Mortgage Loans
     to the Interest Reserve Account as and when required by Section 3.04(c);

               (viii) to pay itself any Net Investment Earnings with respect to
     the Collection Account for any related Investment Period; and

               (ix) to clear and terminate the Collection Account at the
     termination of this Agreement pursuant to Section 9.01.

          On or prior to a Distribution Date, the Trustee shall be entitled to
withdraw amounts that are payable or reimbursable as set forth in clauses (ii)
through (viii) above from the Collection Account prior to making distributions
to Certificateholders on such Distribution Date.

          (c) On each Trust Master Servicer Remittance Date in March (commencing

deposit in the Collection Account all Interest Reserve Amounts that have been
deposited in the Interest Reserve Account in respect of the Interest Reserve

immediately prior to the Final Distribution Date, the Trustee shall withdraw
from the Excess Liquidation Proceeds Account and deposit in the Collection
Account, for distribution on such Distribution Date, any and all amounts then on

     to the application of such Loss of Value Payments) incurred with respect to
     such Trust Mortgage Loan or any successor REO Trust Mortgage Loan with
     respect thereto; and

               (iv) following the occurrence of a Liquidation Event with respect

     Account under this Section 3.05A;

               (xxii) if the related Co-Lender Agreement permits any related
     Non-Trust Mortgage Loan Noteholder to cure defaults under the Trust
     Mortgage Loan included in the subject Serviced Loan Combination, to
     reimburse any amounts paid by the applicable Non-Trust Mortgage Loan
     Noteholder in connection with exercising such cure rights, such Non-Trust
     Mortgage Loan Noteholder's right to reimbursement under this clause (xviii)
     to be limited to amounts on deposit in the related Loan Combination
     Custodial Account that represent collections on the subject Serviced Loan
     Combination that are specifically allocable to such reimbursement in
     accordance with the related Co-Lender Agreement; and

               (xxiii) to clear and terminate such Loan Combination Custodial
     Account at the termination of this Agreement pursuant to Section 9.01.

          The Master Servicer shall keep and maintain separate accounting
records in connection with any withdrawal from each Loan Combination Custodial
Account pursuant to clauses (ii) through (xviii) of the preceding paragraph.


                                     -181-



          (b) The Master Servicer shall pay to each of the Special Servicer (or
to third-party contractors at the direction of the Special Servicer), the
Trustee or any Fiscal Agent, as applicable, from each Loan Combination Custodial
Account, amounts permitted to be paid thereto from such account promptly upon
receipt of a written statement of (i) a Servicing Officer of the Special
Servicer or (ii) a Responsible Officer of the Trustee or such Fiscal Agent, as
the case may be, in each case describing the item and amount to which the
Special Servicer (or such third-party contractor), the Trustee or such Fiscal
Agent, as the case may be, is entitled (unless such payment to the Special
Servicer, the Trustee or such Fiscal Agent, as the case may be, is clearly
required pursuant to this Agreement, in which case written statements shall not
be required). The Master Servicer may rely conclusively on any such written
statement and shall have no duty to re-calculate the amounts stated therein. The
parties seeking payment pursuant to this section shall each keep and maintain
separate accounting for the purpose of justifying any request for withdrawal
from each Loan Combination Custodial Account, on a loan-by-loan basis.

          In the case of each Serviced Loan Combination, the Master Servicer
shall remit or cause to be remitted to each Serviced Non-Trust Mortgage Loan
Noteholder, within one Business Day of the Master Servicer's receipt thereof,
late collections (not including Principal Prepayments) received on the related
Serviced Non-Trust Mortgage Loan subsequent to the related Determination Date
therefor in any particular month (exclusive of any portion of such amount
payable or reimbursable to any third party in accordance in accordance with this
Agreement and the related Co-Lender Agreement), to the extent such amount is not
otherwise included or scheduled to be included in a normal monthly remittance
during such month to such Serviced Non-Trust Mortgage Loan Noteholder and in
respect of which an advance is required to be made or has been made by a service
provider of the related securitization trust.

          To the extent (i) consistent with the Co-Lender Agreement for the
related Serviced Loan Combination and (ii) not otherwise included as part of the
normal monthly remittance, the Master Servicer shall transfer from each Loan
Combination Custodial Account to the Pool Custodial Account, promptly upon
amounts for such purposes becoming available in such Loan Combination Custodial
Account, the aggregate of all Additional Trust Fund Expenses and/or any other
amounts relating to such Serviced Loan Combination, that have been previously
paid out of the Pool Custodial Account pursuant to Section 3.05(a) and that, if
not previously paid out of the Pool Custodial Account in accordance with Section
3.05(a), would have been otherwise payable from such Loan Combination Custodial
Account under this Section 3.05A.

          In accordance with Article IV of the Co-Lender Agreement for each
Serviced Loan Combination (or, in the case of the One New York Plaza Loan
Combination, in accordance with Section 3 of the One New York Plaza Co-Lender
Agreement), the Master Servicer shall, as and when required thereunder (or, if
no date is specified therein, on each applicable Loan Combination Master
Servicer Remittance Date), withdraw from the related Loan Combination Custodial
Account and (i) transfer to the Pool Custodial Account all amounts required to
be remitted to the Trust with respect to the Trust Mortgage Loan included in
such Serviced Loan Combination and/or any successor REO Trust Mortgage Loan with
respect thereto, pursuant to the related Co-Lender Agreement, and (ii) remit to
the related Serviced Non-Trust Mortgage Loan Noteholder(s) all amounts required
to be remitted thereto with respect to the Serviced Non-Trust Mortgage Loan(s)
included in such Serviced Loan Combination and/or any successor REO Mortgage
Loan with respect thereto, pursuant to the related Co-Lender Agreement. Monthly
remittances to the holder(s) of the Non-Trust Mortgage Loan(s) included in any
Serviced Loan Combination and/or any successor REO Mortgage Loan(s) with respect
thereto shall, in


                                     -182-



each case, be made as and when required under the related Co-Lender Agreement
(or, if no date is specified therein, on the applicable Loan Combination Master
Servicer Remittance Date) in accordance with the reasonable instructions of such
respective holder(s), including as to the method of payment (which shall be by
wire transfer of immediately available funds).

          In connection with each Serviced Loan Combination that includes any
Specially Designated Securitized Non-Trust Mortgage Loan, if the Master Servicer
fails, on or before any applicable Loan Combination Master Servicer Remittance
Date for such Loan Combination, to remit to the holder of such Non-Trust
Mortgage Loan any amount(s) required to be so remitted to such holder hereunder
on or before such date, the Master Servicer shall pay to such holder, for the
account of such holder, interest, calculated at the federal funds rate (or such
other rate as may be provided for under the related Co-Lender Agreement), on
such amount(s) not timely remitted, from and including such Loan Combination
Master Servicer Remittance Date to but not including the date on which the
required remittance is made.

          SECTION 3.06.  Investment of Funds in the Collection Account, the
                         Servicing Accounts, the Reserve Accounts, the
                         Defeasance Deposit Account, the Custodial Accounts, the
                         REO Accounts, the Interest Reserve Account and the
                         Excess Liquidation Proceeds Account.

          (a) (i) The Master Servicer may direct in writing any depository
institution maintaining a Servicing Account, a Reserve Account, the Defeasance
Deposit Account or a Custodial Account (any of the foregoing accounts listed in
this clause (i), a "Master Servicer Account"), (ii) the Special Servicer may
direct in writing any depository institution maintaining an REO Account, and
(iii) the Trustee may direct (pursuant to a standing order or otherwise) any
depository institution maintaining the Collection Account, the Interest Reserve
Account or the Excess Liquidation Proceeds Account (any of the foregoing
accounts listed in this clause (iii), a "Trustee Account"; and any of the Master
Servicer Accounts, the REO Accounts and Trustee Accounts, an "Investment
Account"), to invest, or if it is such depository institution, may itself
invest, the funds held therein (other than, in the case of the Pool Custodial
Account, the Interest Reserve Account and the Collection Account, the Initial
Deposits) in one or more Permitted Investments bearing interest or sold at a
discount, and maturing, unless payable on demand, (x) no later than the Business
Day immediately preceding the next succeeding date on which such funds are
required to be withdrawn from such account pursuant to this Agreement or (y) if
and to the extent that the depository institution maintaining such Investment
Account is the obligor on such investment, no later than the time and date as of
which such funds are required to be withdrawn from such account pursuant to this
Agreement (but in any event prior to distributions on the Certificates or any
transfers to another Investment Account being made on or before the related
Distribution Date); provided that in the case of any Servicing Account, any
Reserve Account or the Defeasance Deposit Account, such investment direction
shall be subject to the related loan documents and applicable law.

          All such Permitted Investments shall be held to maturity, unless
payable on demand. Any investment of funds in an Investment Account shall be
made in the name of the Trustee (in its capacity as such) and, in the case of a
Permitted Investment in any Investment Account solely related to a Serviced Loan
Combination, the related Serviced Non-Trust Mortgage Loan Noteholder(s). The
Master Servicer (with respect to Permitted Investments of amounts in the Master
Servicer Accounts) and the Special Servicer (with respect to Permitted
Investments of amounts in the REO Accounts), on behalf


                                     -183-



of the Trustee and, in the case of any Investment Account solely related to a
Serviced Loan Combination, the related Serviced Non-Trust Mortgage Loan
Noteholder(s), or the Trustee in its capacity as such (in the case of any
Trustee Account), shall (i) be the "entitlement holder" of any Permitted
Investment that is a "security entitlement" and (ii) maintain "control" of any
Permitted Investment that is a "certificated security", "uncertificated
security" or "deposit account". The Trustee hereby designates the Master
Servicer (with respect to Permitted Investments of amounts in the Master
Servicer Accounts) and the Special Servicer (with respect to Permitted
Investments of amounts in the REO Accounts), as applicable, as the Person that
shall be the "entitlement holder" and maintain "control" as set forth under
clauses (i) and (ii) above. For purposes of this Section 3.06(a), (i) the terms
"entitlement holder", "security entitlement", "control" (except with respect to
deposit accounts), "certificated security" and "uncertificated security" shall
have the meanings given such terms in Revised Article 8 (1994 Revision) of the
UCC, and the terms "control" (with respect to deposit accounts) and "deposit
account" shall have the meanings given such terms in Revised Article 9 (1998
Revision) of the UCC, and (ii) "control" of any Permitted Investment in any
Investment Account by the Master Servicer or the Special Servicer shall
constitute "control" by a Person designated by, and acting on behalf of, the
Trustee and, in the case of any Investment Account solely related to a Serviced
Loan Combination, the related Serviced Non-Trust Mortgage Loan Noteholder(s),
for purposes of Revised Article 8 (1994 Revision) of the UCC or Revised Article
9 (1998 Revision) of the UCC, as applicable. If amounts on deposit in an
Investment Account are at any time invested in a Permitted Investment payable on
demand, the Master Servicer (in the case of any Master Server Account), the
Special Servicer (in the case of the REO Accounts) or the Trustee (in the case
of any Trustee Account) shall:

          (x)  consistent with any notice required to be given thereunder,
               demand that payment thereon be made on the last day such
               Permitted Investment may otherwise mature hereunder in an amount
               equal to at least the lesser of (1) all amounts then payable
               thereunder and (2) the amount required to be withdrawn on such
               date; and

          (y)  demand payment of all amounts due thereunder promptly upon
               determination by the Master Servicer, the Special Servicer or the
               Trustee, as the case may be, that such Permitted Investment would
               not constitute a Permitted Investment in respect of funds
               thereafter on deposit in the Investment Account.

          (b) Whether or not the Master Servicer directs the investment of funds
in any of the Master Servicer Accounts, interest and investment income realized
on funds deposited therein, to the extent of the Net Investment Earnings, if
any, for each such Investment Account for each related Investment Period (and,
in the case of Servicing Accounts, Reserve Accounts and the Defeasance Deposit
Account, to the extent not otherwise payable to Mortgagors under applicable law
or the related loan documents), shall be for the sole and exclusive benefit of
the Master Servicer and shall be subject to its withdrawal in accordance with
Section 3.03(a), 3.03(d), 3.04(a), 3.04A(b), 3.05(a) or 3.05A, as applicable.
Whether or not the Special Servicer directs the investment of funds in any of
the REO Accounts, interest and investment income realized on funds deposited
therein, to the extent of the Net Investment Earnings, if any, for such
Investment Account for each related Investment Period, shall be for the sole and
exclusive benefit of the Special Servicer and shall be subject to its withdrawal
in accordance with Section 3.16(b). Whether or not the Trustee directs the
investment of funds in any of the Trustee Accounts, interest and investment
income realized on funds deposited therein, to the extent of the Net Investment
Earnings, if any, for such Investment Account for each related Investment
Period, shall be for the sole and exclusive benefit of the Trustee and shall be
subject to its withdrawal in


                                     -184-



accordance with Section 3.05(b), 3.05(c) or 3.05(d), as the case may be. If any
loss shall be incurred in respect of any Permitted Investment on deposit in any
Investment Account, the Master Servicer (in the case of (i) the Servicing
Accounts, the Reserve Accounts and the Defeasance Deposit Account (except to the
extent that any investment of funds with respect thereto is at the direction of
a Mortgagor in accordance with the related loan documents or applicable law) and
(ii) the Custodial Accounts), the Special Servicer (in the case of the REO
Accounts) and the Trustee (in the case of any Trustee Account) shall promptly
deposit therein from its own funds, without right of reimbursement, no later
than the end of the related Investment Period, during which such loss was
incurred, the amount of the Net Investment Loss, if any, for such Investment
Account for such Investment Period. Notwithstanding any of the foregoing
provisions of this Section 3.06, no party shall be required under this Agreement
to deposit any loss on a deposit of funds in an Investment Account if such loss
is incurred solely as a result of the insolvency of the federal or state
chartered depository institution or trust company with which such deposit was
maintained so long as such depository institution or trust company satisfied the
conditions set forth in the definition of "Eligible Account" at the time such
deposit was made and also as of a date no earlier than 30 days prior to the
insolvency.

          (c) Except as expressly provided otherwise in this Agreement, if any
default occurs in the making of a payment due under any Permitted Investment, or
if a default occurs in any other performance required under any Permitted
Investment, the Trustee may, and subject to Section 8.02, upon the request of
the Certificateholders entitled to a majority of the Voting Rights allocated to
any Class, shall take such action as may be appropriate to enforce such payment
or performance, including the institution and prosecution of appropriate
proceedings.

          (d) Notwithstanding the investment of funds held in any Investment
Account, for purposes of the calculations hereunder, including the calculation
of the Available Distribution Amount and the Master Servicer Remittance Amount,
the amounts so invested shall be deemed to remain on deposit in such Investment
Account.

          (e) Notwithstanding the foregoing, the Initial Deposits shall remain
uninvested.

          SECTION 3.07.  Maintenance of Insurance Policies; Errors and Omissions
                         and Fidelity Coverage; Environmental Insurance.

          (a) The Master Servicer shall use reasonable efforts, consistent with
the Servicing Standard, to cause to be maintained for each Mortgaged Property
that secures a Serviced Mortgage Loan and is not an REO Property, all insurance
coverage as is required under the related Mortgage Loan (except to the extent
that the failure to maintain such insurance coverage is an Acceptable Insurance
Default); provided that, if and to the extent that any such Mortgage permits the
holder thereof any discretion (by way of consent, approval or otherwise) as to
the insurance coverage that the related Mortgagor is required to maintain, the
Master Servicer or Special Servicer, as the case may be, shall exercise such
discretion in a manner consistent with the Servicing Standard; and provided,
further, that, if and to the extent that a Mortgage so permits, the Master
Servicer or Special Servicer, as the case may be, shall use reasonable efforts
to require the related Mortgagor to obtain the required insurance coverage from
Qualified Insurers that have, in each such case, the applicable Required Insurer
Rating; and provided, further, that the Master Servicer shall cause to be
maintained, with Qualified Insurers that have, in each such case, the applicable
Required Insurer Rating, for any such Mortgaged Property any such insurance that
the related Mortgagor is required but fails to maintain, but only to the extent
that


                                     -185-



(i) the Trustee (as mortgagee of record on behalf of the Certificateholders or,
in the case of a Mortgaged Property that secures a Serviced Loan Combination,
the Certificateholders and the related Non-Trust Mortgage Loan Noteholder(s))
has an insurable interest, and (ii) either (A) such insurance is available at a
commercially reasonable rate, or (B) solely in the case of all-risk insurance or
other insurance that covers losses from acts of terrorism, the failure by the
Mortgagor to maintain such insurance has not been determined by the Special
Servicer, in accordance with the Servicing Standard, to constitute an Acceptable
Insurance Default. The related Serviced Loan Combination Controlling Party (in
the case of a Mortgaged Property that secures a Serviced Loan Combination), the
Class HAF Representative or the Class SBC Representative, as applicable (in the
case of a Mortgaged Property that secures a Split Trust Mortgage Loan during a
Class HAF Control Period or Class SBC Control Period, as the case may be, with
respect thereto), or the Controlling Class Representative (in the case of any
other Mortgaged Property securing a Serviced Mortgage Loan) may request that
earthquake insurance be secured for such Mortgaged Property by the related
Mortgagor, to the extent that (i) such insurance may be obtained at a
commercially reasonable price and (ii) the related loan documents and applicable
law give the mortgagee the right to request such insurance coverage and such
loan documents require the Mortgagor to obtain earthquake insurance at the
request of the mortgagee. Subject to Section 3.17(a), the Special Servicer, in
accordance with the Servicing Standard, shall also cause to be maintained for
each Administered REO Property no less insurance coverage than was previously
required of the Mortgagor under the related Mortgage; provided that such
insurance is available at commercially reasonable rates and the subject hazards
are at the time commonly insured against for properties similar to the subject
Administered REO Property located in or around the region in which such
Administered REO Property is located (or, in the case of all-risk insurance or
other insurance that covers acts of terrorism, the Special Servicer has
determined, in accordance with the Servicing Standard, that either such
insurance is available at a commercially reasonable rate or the subject hazards
are at the time commonly insured against for properties similar to the subject
Administered REO Property located in or around the region in which such
Administered REO Property is located); and provided, further, that all such
insurance shall be obtained from Qualified Insurers that have, in each such
case, the applicable Required Insurer Rating. All such insurance policies shall
contain (if they insure against loss to property and do not relate to an REO
Property) a "standard" mortgagee clause, with loss payable to the Master
Servicer (in the case of insurance maintained in respect of Serviced Mortgage
Loans, including Specially Serviced Mortgage Loans), and shall be in the name of
the Special Servicer (in the case of insurance maintained in respect of
Administered REO Properties), on behalf of the Trustee. If the Special Servicer
is in the process of making a determination, in the case of all-risk insurance
or other insurance that covers losses from acts of terrorism, as to whether the
failure by the Mortgagor under any Serviced Mortgage Loan to maintain such
insurance constitutes an Acceptable Insurance Default, then, during the period
of such evaluation by the Special Servicer (or, to the extent applicable, during
the period that the Special Servicer is obtaining the consent under Section 6.11
of the Controlling Class Representative or, with respect to a Split Trust
Mortgage Loan, the Loan-Specific Class Representative or, with respect to a
Serviced Loan Combination, obtaining the consent under Section 6.12 of the
Serviced Loan Combination Controlling Party) the Master Servicer shall not be
liable for any loss related to its failure to require the related Mortgagor to
maintain terrorism insurance and shall not be in default of its obligations
hereunder as a result of such failure to maintain terrorism insurance (provided,
that the Master Servicer used reasonable efforts, in accordance with the
Servicing Standard, to cause such Mortgagor to maintain such insurance and has
given prompt written notice to the Special Servicer of its determination that it
will not be successful in its efforts to cause the Mortgagor to obtain such
insurance, along with its determination, and any information in its possession,
regarding the availability and cost of such insurance). The


                                     -186-



Special Servicer shall promptly notify the Master Servicer of each such
determination by the Special Servicer under this paragraph.

          Any amounts collected by the Master Servicer or the Special Servicer
under any such policies (other than amounts to be applied to the restoration or
repair of the related Mortgaged Property or REO Property or amounts to be
released to the related Mortgagor, in each case subject to the rights of any
tenants and ground lessors, as the case may be, and in each case in accordance
with the terms of the related Mortgage and the Servicing Standard) shall be
deposited in the applicable Custodial Account in accordance with Section 3.04(a)
or 3.04A(a), as applicable, in the case of amounts received in respect of a
Serviced Mortgage Loan, or in the applicable REO Account in accordance with
Section 3.16(b), in the case of amounts received in respect of an Administered
REO Property. Any cost incurred by the Master Servicer or the Special Servicer
in maintaining any such insurance (including any earthquake insurance maintained
at the request of a Serviced Loan Combination Controlling Party or the
Controlling Class Representative, as applicable) shall not, for purposes hereof,
including calculating monthly distributions to Certificateholders, be added to
the unpaid principal balance or Stated Principal Balance of the related Serviced
Mortgage Loan(s) or REO Mortgage Loan(s), notwithstanding that the terms of such
loan so permit, but shall be recoverable by the Master Servicer or the Special
Servicer, as applicable, as a Servicing Advance.

          (b) If either the Master Servicer or the Special Servicer shall obtain
and maintain, or cause to be obtained and maintained, a blanket policy or master
force placed policy insuring against hazard losses on all of the Serviced
Mortgage Loans and/or Administered REO Properties that it is required to service
and administer, then, to the extent such policy (i) is obtained from a Qualified
Insurer having (or whose obligations are guaranteed or backed, in writing, by an
entity having) the applicable Required Insurer Rating, and (ii) provides
protection equivalent to the individual policies otherwise required, then the
Master Servicer or the Special Servicer, as the case may be, shall conclusively
be deemed to have satisfied its obligation to cause hazard insurance to be
maintained on the related Mortgaged Properties and/or the subject Administered
REO Properties. Such blanket policy or master force placed policy may contain a
deductible clause (not in excess of a customary amount), in which case the
Master Servicer or the Special Servicer, as appropriate, shall, if there shall
not have been maintained on the related Mortgaged Property or subject
Administered REO Property an individual hazard insurance policy complying with
the requirements of Section 3.07(a), and there shall have been one or more
losses that would have been covered by such individual policy, promptly deposit
into the applicable Custodial Account from its own funds the amount not
otherwise payable under the blanket policy or master force placed policy because
of the deductible clause therein, to the extent that any such deductible exceeds
the deductible limitation that pertained to the related Serviced Mortgage Loan
(or in the absence of any such deductible limitation, the deductible limitation
for an individual policy which is consistent with the Servicing Standard). The
Master Servicer or the Special Servicer, as appropriate, shall prepare and
present, on behalf of itself, the Trustee, the Certificateholders and, in the
case of a Mortgaged Property that secures a Serviced Loan Combination, the
related Non-Trust Mortgage Loan Noteholder(s), claims under any such blanket
policy or master force placed policy in a timely fashion in accordance with the
terms of such policy.

          (c) Subject to the third paragraph of this Section 3.07(c), each of
the Master Servicer and the Special Servicer shall at all times during the term
of this Agreement (or, in the case of the Special Servicer, at all times during
the term of this Agreement in which Specially Serviced Mortgage Loans and/or
Administered REO Properties are part of the Trust Fund) keep in force with
Qualified


                                     -187-



Insurers that, in each such case, has (or whose obligations are in each such
case guaranteed or backed, in writing, by an entity that has) the applicable
Required Insurer Rating, a fidelity bond, which fidelity bond shall be in such
form and amount as would permit it to be a qualified Fannie Mae seller-servicer
of multifamily mortgage loans, or in such other form and amount as would not
cause an Adverse Rating Event with respect to any Class of Certificates (as
evidenced in writing from each Rating Agency). Each of the Master Servicer and
the Special Servicer shall be deemed to have complied with the foregoing
provision if an Affiliate thereof has such fidelity bond coverage and, by the
terms of such fidelity bond, the coverage afforded thereunder extends to the
Master Servicer or the Special Servicer, as the case may be.

          Subject to the third paragraph of this Section 3.07(c), each of the
Master Servicer and the Special Servicer shall at all times during the term of
this Agreement (or, in the case of the Special Servicer, at all times during the
term of this Agreement in which Specially Serviced Mortgage Loans and/or
Administered REO Properties are part of the Trust Fund) also keep in force with
Qualified Insurers that, in each such case, has (or whose obligations are in
each such case guaranteed or backed, in writing, by an entity that has) the
applicable Required Insurer Rating, a policy or policies of insurance covering
loss occasioned by the errors and omissions of its officers and employees in
connection with its servicing obligations hereunder, which policy or policies
shall be in such form and amount as would permit it to be a qualified Fannie Mae
seller-servicer of multifamily mortgage loans, or in such other form and amount
as would not cause an Adverse Rating Event with respect to any Class of
Certificates (as evidenced in writing from each Rating Agency). Each of the
Master Servicer and the Special Servicer shall be deemed to have complied with
the foregoing provisions if an Affiliate thereof has such insurance and, by the
terms of such policy or policies, the coverage afforded thereunder extends to
the Master Servicer or the Special Servicer, as the case may be.

          Notwithstanding the foregoing, for so long as the long-term debt
obligations of the Master Servicer or Special Servicer (or its direct corporate
parent if such parent is responsible for the obligations of the Master Servicer
or Special Servicer, as applicable), as the case may be, are rated at least "A"
from S&P and "A3" from Moody's (or, in the case of any such Rating Agency, such
lower rating as will not result in an Adverse Rating Event with respect to any
Class of Certificates rated by such Rating Agency, as evidenced in writing by
such Rating Agency), such Person may self-insure with respect to the risks
described in this Section 3.07(c).

          (d) In the event that either of the Master Servicer or the Special
Servicer has actual knowledge of any event (an "Insured Environmental Event")
giving rise to a claim under any Environmental Insurance Policy in respect of
any Environmentally Insured Mortgage Loan (other than, if applicable, an Outside
Serviced Trust Mortgage Loan) for which the Mortgagor has not filed a claim or
in respect of an Administered REO Property, the Master Servicer shall notify the
Special Servicer if such Mortgage Loan is a Specially Serviced Mortgage Loan,
and the Special Servicer shall notify the Master Servicer in all cases. Upon
becoming aware of such Insured Environmental Event, the Master Servicer, in the
case of a Performing Serviced Mortgage Loan, and the Special Servicer, in the
case of a Specially Serviced Mortgage Loan or an Administered REO Property, in
accordance with the terms of such Environmental Insurance Policy and the
Servicing Standard, shall timely make a claim thereunder with the appropriate
insurer and shall take such other actions necessary under such Environmental
Insurance Policy in order to realize the full value thereof for the benefit of
the Certificateholders. With respect to each Environmental Insurance Policy in
respect of an Environmentally Insured Mortgage Loan (other than, if applicable,
an Outside Serviced Trust Mortgage Loan), the Master Servicer (in the


                                     -188-



case of any such Mortgage Loan that is a Performing Serviced Mortgage Loan) and
the Special Servicer (in the case of any such Mortgage Loan that is a Specially
Serviced Mortgage Loan or in the case of an Administered REO Property) shall
each review and familiarize itself with the terms and conditions relating to
enforcement of claims and shall, in the event the Master Servicer or the Special
Servicer has actual knowledge of an Insured Environmental Event giving rise to a
claim under such policy, monitor the dates by which any claim must be made or
any action must be taken under such policy to realize the full value thereof for
the benefit of the Certificateholders.

          The Master Servicer (in the case of Performing Serviced Mortgage
Loans) and the Special Servicer (in the case of Specially Serviced Mortgage
Loans and Administered REO Properties) shall each abide by the terms and
conditions precedent to payment of claims under the Environmental Insurance
Policies with respect to the Environmentally Insured Mortgage Loans (other than,
if applicable, any Outside Serviced Trust Mortgage Loan) and take all such
actions as may be required to comply with the terms and provisions of such
policies in order to maintain such policies in full force and effect and to make
claims thereunder.

          In the event that either the Master Servicer or the Special Servicer
receives notice of a termination of any Environmental Insurance Policy with
respect to an Environmentally Insured Mortgage Loan (other than, if applicable,
an Outside Serviced Trust Mortgage Loan), then the party receiving such notice
shall, within five (5) Business Days after receipt thereof, provide written
notice of such termination to the other such party and the Trustee. Upon receipt
of such notice, the Master Servicer, with respect to a Performing Serviced
Mortgage Loan, or the Special Servicer, with respect to a Specially Serviced
Mortgage Loan or an Administered REO Property, shall address such termination in
accordance with Section 3.07(a). Any legal fees, premiums or other out-of-pocket
costs incurred in accordance with the Servicing Standard in connection with
enforcing the obligations of the Mortgagor under any Environmental Insurance
Policy or a resolution of such termination of an Environmental Insurance Policy
shall be paid by the Master Servicer and shall be reimbursable to it as a
Servicing Advance.

          The Master Servicer (with respect to Performing Serviced Mortgage
Loans) and the Special Servicer (with respect to Specially Serviced Mortgage
Loans) shall monitor the actions, and enforce the obligations, of the related
Mortgagor under each Environmentally Insured Mortgage Loan (other than, if
applicable, an Outside Serviced Trust Mortgage Loan) insofar as such
actions/obligations relate to (i) to the extent consistent with Section 3.07(a),
the maintenance (including, without limitation, any required renewal) of an
Environmental Insurance Policy with respect to the related Mortgaged Property or
(ii) environmental testing or remediation at the related Mortgaged Property.

          SECTION 3.08.  Enforcement of Alienation Clauses.

          (a) If, with respect to any Performing Serviced Mortgage Loan, the
Master Servicer receives a request from a Mortgagor regarding the transfer of
the related Mortgaged Property to, and assumption of such Performing Serviced
Mortgage Loan by, another Person and/or transfers of certain interests in such
Mortgagor (including, without limitation, sales or transfers of the related
Mortgaged Property (in full or in part) or the sale, transfer, pledge or
hypothecation of direct or indirect interests in the related Mortgagor or its
owners) or, in the case of a Performing Serviced Mortgage Loan that by its terms
permits transfer or assumption without the consent of the lender so long as
certain conditions are satisfied, a request by the related Mortgagor for a
determination that such conditions have been satisfied,


                                     -189-



then the Master Servicer shall immediately notify the Special Servicer of such
request, shall evaluate (consistent with the Servicing Standard) the experience
and financial condition of the proposed transferee and the status of any
conditions to transfer or assumption (as described above) and prepare a report
in connection therewith and shall deliver to the Special Servicer such report
and any documents or other materials that the Master Servicer shall have
received regarding the proposed transfer and, if applicable, the proposed
assumption. The Special Servicer shall have the right hereunder, within 15 days
(or, in the case of a consent to a determination as to whether the conditions
precedent to the subject transfer or assumption have been satisfied, within 10
days) of receipt of such recommendation and supporting materials and any other
materials reasonably requested by the Special Servicer, in accordance with the
Servicing Standard, to withhold or grant consent to any such request for such
transfer and/or assumption and/or to make a determination as to whether the
conditions to transfer or assumption (as described above) have been satisfied,
as applicable, each in accordance with the terms of the subject Performing
Serviced Mortgage Loan and this Agreement; provided that any grant of consent on
the part of the Special Servicer shall be subject to Section 3.08(d), Section
6.11 and/or Section 6.12, in each case if and as applicable. If the Special
Servicer, in accordance with the Servicing Standard, (i) withholds or denies its
consent to any such request for such transfer and/or assumption with respect to
any Performing Serviced Mortgage Loan and/or (ii) determines, with respect to
any Performing Serviced Mortgage Loan that by its terms permits transfer and/or
assumption without lender consent so long as certain conditions are satisfied,
that such conditions have not been satisfied, then, in each such case, the
Special Servicer shall notify the Master Servicer in writing of such
determination, and the Master Servicer shall notify the related Mortgagor that
the requested transfer and/or assumption will not be permitted and shall
restrict the requested transfer and/or assumption of the subject Performing
Serviced Mortgage Loan in accordance with the Servicing Standard. If the Special
Servicer consents to such proposed transfer and/or assumption and/or determines
that the conditions to transfer or assumption have been satisfied, the Master
Servicer shall process such request of the related Mortgagor; and, in the case
of a transfer of the related Mortgaged Property to, and assumption of such
Performing Serviced Mortgage Loan by, another Person, the Master Servicer
(subject to Section 3.08(d)) shall be authorized to enter into an assumption or
substitution agreement with the Person, which shall be a Single Purpose Entity,
to whom the related Mortgaged Property has been or is proposed to be conveyed
and/or release the original Mortgagor from liability under such Performing
Serviced Mortgage Loan and substitute as obligor thereunder the Person to whom
the related Mortgaged Property has been or is proposed to be conveyed; provided,
however, that the Master Servicer shall not enter into any such agreement to the
extent that any terms thereof would result in an Adverse REMIC Event or Adverse
Grantor Trust Event or create any lien on a Mortgaged Property that is senior
to, or on parity with, the lien of the related Mortgage. The Master Servicer
shall notify the Trustee, the Special Servicer, each Rating Agency, the
Controlling Class Representative and, in the case of a Serviced Loan Combination
that consists of Performing Serviced Mortgage Loans, the related Serviced
Non-Trust Mortgage Loan Noteholder(s) and, in the case of a Split Trust Mortgage
Loan, the applicable Loan-Specific Class Representative, of any assumption or
substitution agreement executed pursuant to this Section 3.08(a) and shall
forward thereto a copy of such agreement together with a Review Package. Subject
to the terms of the related loan documents, no assumption of a
Cross-Collateralized Mortgage Loan shall be made without the assumption of all
other Serviced Trust Mortgage Loans making up the related Cross-Collateralized
Group. Further, subject to the terms of the related loan documents and
applicable law, no assumption of a Serviced Mortgage Loan shall be made or
transfer of interest in a Mortgagor approved, unless all costs in connection
therewith, including any arising from seeking Rating Agency confirmation, are
paid by the related Mortgagor.


                                     -190-



          (b) If, with respect to a Specially Serviced Mortgage Loan, the Master
Servicer receives a request from a Mortgagor for consent to a transfer of the
related Mortgaged Property and assumption of such Specially Serviced Mortgage
Loan and/or consent to a transfer of interests in the related Mortgagor
(including, without limitation, sales or transfers of the related Mortgaged
Property (in full or in part) or the sale, transfer, pledge or hypothecation of
direct or indirect interests in the related Mortgagor or its owners) or in the
case of a Specially Serviced Mortgage Loan that by its terms permits transfer or
assumption without the consent of the lender so long as certain conditions are
satisfied, a request by the related Mortgagor for a determination that such
conditions have been satisfied, the Master Servicer shall immediately notify the
Special Servicer of such request and deliver to the Special Servicer any
documents that the Master Servicer shall have received regarding the proposed
transfer and assumption. Subject to Section 3.08(d), Section 6.11 and/or Section
6.12, in each case if and as applicable, the Special Servicer shall determine
whether to grant such consent, whether the conditions to transfer or assumption
(as described above) have been satisfied and/or whether to enforce any
restrictions on such transfer and/or assumption contained in the related loan
documents, as applicable, each in accordance with the Servicing Standard.

          Upon consent by the Special Servicer to any proposed transfer of a
Mortgaged Property and assumption by the proposed transferee of the related
Serviced Mortgage Loan pursuant to this Section 3.08(b), the Special Servicer
shall process the request of the related Mortgagor for such transfer and
assumption and shall be authorized to enter into an assumption or substitution
agreement with the Person, which shall be a Single Purpose Entity, to whom the
related Mortgaged Property has been or is proposed to be conveyed and/or release
the original Mortgagor from liability under the related Serviced Mortgage Loan
and substitute as obligor thereunder the Person to whom the related Mortgaged
Property has been or is proposed to be conveyed; provided, however, that the
Special Servicer shall not enter into any such agreement to the extent that any
terms thereof would result in an Adverse REMIC Event or Adverse Grantor Trust
Event or create any lien on a Mortgaged Property that is senior to, or on parity
with, the lien of the related Mortgage. The Special Servicer shall notify the
Trustee, the Master Servicer, each Rating Agency, the Controlling Class
Representative and, with respect to a Serviced Loan Combination, the related
Serviced Non-Trust Mortgage Loan Noteholder(s), of any assumption or
substitution agreement executed pursuant to this Section 3.08(b) and shall
forward thereto a copy of such agreement. Subject to the terms of the related
loan documents, no assumption of a Cross-Collateralized Mortgage Loan shall be
made without the assumption of all other Serviced Trust Mortgage Loans making up
the related Cross-Collateralized Group. Further, subject to the terms of the
related loan documents and applicable law, no assumption of a Serviced Mortgage
Loan shall be made unless all costs in connection therewith, including any
arising from seeking Rating Agency confirmation, are paid by the related
Mortgagor.

          As used in this Section 3.08, the terms "sale" and "transfer" shall
include the matters contemplated by the parentheticals in the first sentence of
Section 3.08(a).

          (c) If, with respect to a Performing Serviced Mortgage Loan, the
Master Servicer receives a request from the related Mortgagor regarding a
further encumbrance of the related Mortgaged Property or of an interest in the
related Mortgagor (including, without limitation, any mezzanine financing of the
related Mortgagor or any direct or indirect owners of the related Mortgagor or
the Mortgaged Property or any sale, issuance or transfer of preferred equity in
the Mortgagor or its owners or, in the case of a Performing Serviced Mortgage
Loan that by its terms permits further encumbrance without the consent of the
lender provided certain conditions are satisfied, a request by the related


                                      -191-



Mortgagor for a determination that such conditions have been satisfied), then
the Master Servicer shall promptly obtain relevant information for purposes of
evaluating such request. If the Master Servicer determines, consistent with the
Servicing Standard, to approve such further encumbrance or that the conditions
precedent to such further encumbrance have been satisfied, as applicable, then
the Master Servicer shall provide to the Special Servicer a written copy of such
recommendation (which shall include the reason therefor) and the materials upon
which such recommendation is based. The Special Servicer shall have the right
hereunder, within 15 days (or, in the case of a consent to a determination as to
whether the conditions precedent to a further encumbrance have been satisfied,
within 10 days), or within such longer period as may be necessary to obtain any
required consent pursuant to Section 6.11 or 6.12, as and if applicable, of
receipt of such recommendation and supporting materials and any other materials
reasonably requested by the Special Servicer, to reasonably withhold or, subject
to Section 3.08(d) and, further, subject to the Special Servicer obtaining any
consent to the extent required pursuant to Section 6.11 and/or Section 6.12, in
each case if and as applicable, grant consent to any such request for such
further encumbrance of the related Mortgaged Property or of an interest in the
related Mortgagor or to object or consent to the determination by the Master
Servicer as to whether the conditions to further encumbrance (as described
above) have been satisfied, as applicable, each in accordance with the terms of
such Performing Serviced Mortgage Loan and this Agreement and subject to the
Servicing Standard. If the Special Servicer does not respond within such 15-day
period or 10-day period, or such longer period as set forth above, as the case
may be, such party's consent shall be deemed granted; provided, that if the
Special Servicer's consent is not deemed granted within the aforementioned
15-day period or 10-day period, as applicable, because the Special Servicer is
in the process of obtaining a consent required pursuant to Section 6.11 and/or
Section 6.12, as applicable, then the Special Servicer shall provide notice to
the Master Servicer of such process and the estimated time period for completion
thereof, of having obtained any applicable rejection or consent for the subject
action and/or of the time period within which any applicable deemed consent from
the Controlling Class Representative will be granted for the subject action, in
each case as and if applicable. If the Special Servicer consents or is deemed to
have consented to such further encumbrance of the related Mortgaged Property or
of an interest in the related Mortgagor, as applicable, the Master Servicer
shall process such request of the related Mortgagor. If the Special Servicer
does not consent to, and is not deemed to have consented to, such further
encumbrance, then the Master Servicer, on behalf of the Trustee (as mortgagee of
record on behalf of the Certificateholders and, with respect to a Serviced Loan
Combination, the related Serviced Non-Trust Mortgage Loan Noteholder(s)) shall,
to the extent permitted by applicable law, enforce the restrictions contained in
the related loan documents on further encumbrances of the related Mortgaged
Property and/or of an interest in the related Mortgagor, as applicable. If the
Special Servicer, in accordance with the Servicing Standard (i) objects (within
a 10-day period) to the determination by the Master Servicer with respect to a
Performing Serviced Mortgage Loan (which by its terms permits further
encumbrance without lender consent provided certain conditions are satisfied)
that the subject conditions have been satisfied, or (ii) determines (within a
10-day period or 15-day period, as applicable) with respect to any other
Serviced Mortgage Loan (which by its terms permits further encumbrance without
lender consent provided certain conditions are satisfied) that the subject
conditions have not been satisfied, then, in each such case, the Special
Servicer shall notify the Master Servicer in writing of such objection or
determination, as applicable, and the Master Servicer shall notify the related
Mortgagor that the requested further encumbrance will not be permitted and shall
restrict the requested further encumbrance of the subject Serviced Mortgage Loan
in accordance with the Servicing Standard. To the extent permitted by the
applicable loan documents and applicable law, the Master Servicer may charge the
related Mortgagor (and retain to the extent permitted under Section 3.11) a fee
in connection with any enforcement or waiver contemplated in this paragraph of
subsection (c).


                                      -192-



          With respect to any Specially Serviced Mortgage Loan, the Special
Servicer, on behalf of the Trustee (as mortgagee of record on behalf of the
Certificateholders and, in the case of a Mortgaged Property that secures a
Serviced Loan Combination, the related Serviced Non-Trust Mortgage Loan
Noteholder(s)) shall, to the extent permitted by applicable law, enforce the
restrictions contained in the related loan documents on further encumbrances of
the related Mortgaged Property and/or of interests in the related Mortgagor, as
applicable, and shall, with respect to Specially Serviced Mortgage Loans that by
their terms permit further encumbrance without mortgagee consent so long as
certain conditions are satisfied, make all determinations as to whether such
conditions have been satisfied, and shall process all documentation in
connection therewith, unless the Special Servicer has determined, in its
reasonable, good faith judgment, that waiver of such restrictions or such
conditions, as the case may be, would be in accordance with the Servicing
Standard (as evidenced by an Officer's Certificate setting forth the basis for
such determination delivered to the Trustee, the Master Servicer, each Rating
Agency and, in the case of a Serviced Loan Combination, the related Serviced
Non-Trust Mortgage Loan Noteholder(s) and, in the case of a Split Trust Mortgage
Loan, the applicable Loan-Specific Class Representative); provided that any such
waiver of such restrictions shall be subject to Section 3.08(d) and Section 6.11
and/or Section 6.12, in each case if and as applicable. To the extent permitted
by the applicable loan documents and applicable law, the Special Servicer may
charge the related Mortgagor (and retain to the extent permitted under Section
3.11) a fee in connection with any enforcement or waiver contemplated in this
paragraph of subsection (c).

          As used in this Section 3.08, the term "encumbrance" shall include the
matters contemplated by the parentheticals in the first sentence of this Section
3.08(c).

          (d) Notwithstanding anything to the contrary contained in this Section
3.08, but subject to the related loan documents and applicable law: (i) if (A)
the then unpaid principal balance of the subject Serviced Trust Mortgage Loan,
together with any other Serviced Trust Mortgage Loans that are
cross-collateralized therewith, is at least equal to the lesser of (1)
$35,000,000 and (2) 5% of the then aggregate principal balance of the Mortgage
Pool or (B) the subject Serviced Trust Mortgage Loan is then one of the ten
largest Trust Mortgage Loans in the Mortgage Pool, then neither the Master
Servicer nor the Special Servicer, as applicable, shall waive any restrictions
contained in the related Mortgage on transfers of the related Mortgaged Property
or on transfers of interests in the related Mortgagor, and (ii) if (W) the then
unpaid principal balance of the subject Serviced Trust Mortgage Loan, together
with any other Serviced Trust Mortgage Loans that are cross-collateralized
therewith, is at least equal to the lesser of (1) $20,000,000 and (2) 2% of the
then aggregate principal balance of the Mortgage Pool or (X) the subject
Serviced Trust Mortgage Loan is then one of the ten largest Trust Mortgage Loans
in the Mortgage Pool or (Y) the aggregate loan-to-value ratio of the subject
Serviced Trust Mortgage Loan (together with any additional loans that would
further encumber the related Mortgaged Property and/or interests in the related
Mortgagor) would be equal to or greater than 85% or (Z) the aggregate debt
service coverage ratio of the related Mortgaged Property (taking into account
any additional loans that would further encumber the related Mortgaged Property
and/or interests in the related Mortgagor) would be less than 1.20x, then
neither the Special Servicer nor the Master Servicer shall waive any
restrictions contained in the related Mortgage on further encumbrances of the
related Mortgaged Property or of interests in the related Mortgagor, unless, in
the case of either (i) or (ii) above, the Master Servicer or the Special
Servicer, as the case may be, shall have received prior written confirmation
from S&P (and, if a Serviced Loan Combination is involved and includes a
Specially Designated Securitized Non-Trust Mortgage Loan, and if any related
Specially Designated Non-Trust Securities are rated by Fitch, from Fitch) that
such action would not result in an Adverse Rating Event with respect to any
Class of


                                      -193-



Certificates or any class of Specially Designated Non-Trust Mortgage Loan
Securities rated by such rating agency. Also notwithstanding anything to the
contrary contained in this Section 3.08, but subject to the related loan
documents and applicable law, if the subject Serviced Trust Mortgage Loan is
then one of the ten largest Trust Mortgage Loans in the Mortgage Pool, then
neither the Master Servicer nor the Special Servicer, as applicable, shall waive
any restrictions contained in the related Mortgage on transfers or further
encumbrances of the related Mortgaged Property or on transfers of interests in
the related Mortgagor, unless the Master Servicer or the Special Servicer, as
the case may be, shall have obtained prior written confirmation from Moody's
that such action would not result in an Adverse Rating Event with respect to any
Class of Certificates rated by such Rating Agency. Neither the Master Servicer
nor the Special Servicer has the authority to perform any of the actions set
forth above in this paragraph with respect to an Outside Serviced Trust Mortgage
Loan. In connection with any request for rating confirmation from a rating
agency pursuant to this paragraph of Section 3.08(d), the Master Servicer or the
Special Servicer, as the case may be, shall deliver a Review Package to such
rating agency. Further, subject to the terms of the related loan documents and
applicable law, no waiver of a restriction contained in the related Mortgage on
transfers of the related Mortgaged Property or interests in the related
Mortgagor or on further encumbrances thereof may be waived by the Master
Servicer or the Special Servicer, as applicable, unless all costs in connection
therewith, including any arising from seeking Rating Agency confirmation, are
paid by the related Mortgagor. To the extent not collected from the related
Mortgagor (or from the Depositor or the UBS Mortgage Loan Seller pursuant to
Section 2.03), any rating agency charges in connection with the foregoing shall
be paid by the Master Servicer as a Servicing Advance.

          Notwithstanding the foregoing, with respect to any Outside Serviced
Trust Mortgage Loan, in the event that any action set forth in clause (i) or
(ii) of the first sentence of the preceding paragraph regarding such Trust
Mortgage Loan would require written confirmation from a Rating Agency that such
action would not result in an Adverse Rating Event with respect to any Class of
Certificates rated by such Rating Agency in accordance with clause (i) or (ii)
of the first sentence of the preceding paragraph if such Trust Mortgage Loan
were a Serviced Trust Mortgage Loan, then the Controlling Class Representative
(and, additionally, the Master Servicer and the Special Servicer, if applicable)
shall not consent to a waiver of any restrictions contained in the related
Mortgage on transfers of the related Mortgaged Property or on transfers of
interests in the related Mortgagor or to a waiver of any restrictions contained
in the related Mortgage on further encumbrances of the related Mortgaged
Property or of interests in the related Mortgagor, in each case to the extent it
is permitted to do so under the related Outside Servicing Agreement and/or the
related Co-Lender Agreement, unless it has obtained written confirmation from
each Rating Agency that such action would not result in an Adverse Rating Event
with respect to any Class of Certificates rated by such Rating Agency. Upon
being asked to consent to any action set forth in the preceding sentence (i) if
the party initially in receipt of such request for consent is the Controlling
Class Representative, the Controlling Class Representative shall request from
the Master Servicer, and the Master Servicer shall thereupon provide, a
determination to the Controlling Class Representative as to, and (ii) if the
party initially in receipt of such request for consent is the Master Servicer,
the Master Servicer shall forward such request to the Controlling Class
Representative together with a determination as to, and (iii) if the party
initially in receipt of such request for consent is the Special Servicer, the
Special Servicer shall forward such request to the Master Servicer and the
Controlling Class Representative, and the Master Servicer shall thereupon
provide a determination to the Controlling Class Representative as to, in the
case of (i), (ii) and (iii) above, whether such action would require written
confirmation from each Rating Agency that such action would not result in an
Adverse Rating Event with respect to any Class of Certificates rated by such


                                      -194-



Rating Agency in accordance with clause (i) or clause (ii) of the first sentence
of the preceding paragraph if such Trust Mortgage Loan were a Serviced Trust
Mortgage Loan (and the Controlling Class Representative shall be entitled to
conclusively rely on such determination by the Master Servicer). Further,
subject to the terms of the related loan documents and applicable law, the
Controlling Class Representative shall not affirmatively consent to a waiver of
any restrictions contained in the related Mortgage on transfers of the related
Mortgaged Property or on transfers of interests in the related Mortgagor or to a
waiver of any restrictions contained in the related Mortgage on further
encumbrances of the related Mortgaged Property or of interests in the related
Mortgagor, unless all costs in connection therewith, including any arising from
seeking Rating Agency confirmation, are paid by the related Mortgagor (unless
requiring payment of such costs by the Mortgagor is contrary to the explicit
terms of the related loan documents). To the extent not payable by and collected
from the related Mortgagor, any rating agency charges in connection with the
foregoing shall be paid by the Master Servicer by withdrawing the amount of such
charges from the Pool Custodial Account.

          If and to the extent that any expenses paid by the Master Servicer in
connection with the actions contemplated by this Section 3.08(d) would result in
the failure of any one or more Holder(s) of Regular Interest Certificates to
receive any amount of principal or interest at the related Pass-Through Rate to
which such Holder(s) are entitled (in each case by the time any such amounts are
due and payable to such Holder(s)), then such amounts shall be deemed to have
been distributed to such Holder(s) from REMIC III, as of the time paid by the
Master Servicer, and then paid by such Holder(s) and not by any of the REMIC
Pools.

          SECTION 3.09.  Realization Upon Defaulted Mortgage Loans; Required
                         Appraisals; Appraisal Reduction Calculation.

          (a) The Special Servicer shall, subject to Sections 3.09(b), 3.09(c),
3.09(d), 6.11 and 6.12, exercise reasonable efforts, consistent with the
Servicing Standard, to foreclose upon or otherwise comparably convert the
ownership of properties securing such of the Specially Serviced Mortgage Loans
as come into and continue in default and as to which no satisfactory
arrangements can be made for collection of delinquent payments, including
pursuant to Section 3.20; provided that neither the Master Servicer nor the
Special Servicer shall, with respect to any Serviced Mortgage Loan that
constitutes an ARD Mortgage Loan after its Anticipated Repayment Date, take any
enforcement action with respect to the payment of Additional Interest (other
than the making of requests for its collection) unless (i) the taking of an
enforcement action with respect to the payment of other amounts due under such
ARD Mortgage Loan is, in the good faith and reasonable judgment of the Special
Servicer, necessary, appropriate and consistent with the Servicing Standard or
(ii) all other amounts due under such ARD Mortgage Loan have been paid, the
payment of such Additional Interest has not been forgiven in accordance with
Section 3.20 and, in the good faith and reasonable judgment of the Special
Servicer, the Liquidation Proceeds expected to be recovered in connection with
such enforcement action will cover the anticipated costs of such enforcement
action and, if applicable, any associated interest accrued on Advances. Subject
to Section 3.11(h), the Special Servicer shall request that the Master Servicer
advance all costs and expenses incurred by it in any such proceedings, and the
Master Servicer shall be entitled to reimbursement therefor as provided in
Section 3.05(a) or Section 3.05A, as applicable. The Special Servicer shall be
responsible, consistent with the Servicing Standard, for determining whether to
exercise any rights it may have under the cross-collateralization and/or
cross-default provisions of a Cross-Collateralized Mortgage Loan. Nothing
contained in this Section 3.09 shall be construed so as to require the Special
Servicer, on behalf of the Certificateholders and, in the


                                      -195-



case of a Mortgaged Property that secures a Serviced Loan Combination, on behalf
of the affected Serviced Non-Trust Mortgage Loan Noteholder(s), to make a bid on
any Mortgaged Property at a foreclosure sale or similar proceeding that is in
excess of the fair market value of such property, as determined by the Special
Servicer in its reasonable and good faith judgment taking into account the
factors described in Section 3.18 and the results of any appraisal obtained as
provided below in this Section 3.09, all such bids to be made in a manner
consistent with the Servicing Standard.

          If and when the Master Servicer or the Special Servicer deems it
necessary and prudent for purposes of establishing the fair market value of any
Mortgaged Property securing a Specially Serviced Mortgage Loan, whether for
purposes of bidding at foreclosure or otherwise, it may have an appraisal
performed with respect to such property by an Independent Appraiser or other
expert in real estate matters, which appraisal shall take into account the
factors specified in Section 3.18, and the cost of which appraisal shall be
covered by, and be reimbursable as, a Servicing Advance; provided that if the
Master Servicer intends to obtain an appraisal in connection with the foregoing,
the Master Servicer shall so notify the Special Servicer and consult with the
Special Servicer regarding such appraisal.

          If any Serviced Mortgage Loan or Serviced Loan Combination becomes a
Required Appraisal Loan, then the Special Servicer shall (i) obtain or conduct,
as applicable, a Required Appraisal within 60 days (or, in the case of a
Serviced Loan Combination, such shorter time period (if any) as may be required
under the related Co-Lender Agreement) of such occurrence (unless a Required
Appraisal was obtained or conducted, as applicable, with respect to such
Required Appraisal Loan within the prior 12 months and the Special Servicer
reasonably believes, in accordance with the Servicing Standard, that no material
change has subsequently occurred with respect to the related Mortgaged Property
that would draw into question the applicability of such Required Appraisal) and
(ii) obtain or conduct, as applicable, an update of the most recent Required
Appraisal approximately 12 months following the most recent Required Appraisal
or subsequent update thereof for so long as such Serviced Mortgage Loan (or any
successor REO Mortgage Loan with respect thereto) or such Serviced Loan
Combination, as the case may be, remains a Required Appraisal Loan. The Special
Servicer shall deliver copies of all such Required Appraisals and updated
Required Appraisals to the Trustee, the Master Servicer and, in the case of a
Mortgaged Property that secures a Serviced Loan Combination, the related
Non-Trust Mortgage Loan Noteholder(s), in each such case, promptly following the
Special Servicer's receipt of the subject appraisal, and, upon request, to the
Controlling Class Representative and, in the case of a Split Trust Mortgage
Loan, the applicable Loan-Specific Class Representative. Based on each such
Required Appraisal and updated Required Appraisal, the Special Servicer shall
(monthly, on each related Determination Date, until the subject Required
Appraisal Loan ceases to be such) calculate and notify the Trustee, the Master
Servicer, the Controlling Class Representative, and, in the case of any
Mortgaged Property that secures a Serviced Loan Combination, the related
Serviced Non-Trust Mortgage Loan Noteholder(s), of any resulting Appraisal
Reduction Amount in respect of the subject Required Appraisal Loan. Such
calculations by the Special Servicer shall be subject to review and confirmation
by the Master Servicer, provided that the Master Servicer may rely on any
information provided by the Special Servicer. The Master Servicer shall, at the
direction of the Special Servicer, advance the cost of each such Required
Appraisal and updated Required Appraisal; provided, however, that such expense
will be subject to reimbursement to the Master Servicer as a Servicing Advance
out of the related Custodial Account pursuant to Section 3.05(a) or Section
3.05A, as applicable. At any time that an Appraisal Reduction Amount exists with
respect to any Required Appraisal Loan, the related Serviced Loan Combination
Controlling Party (in the case of a Serviced Loan Combination or related REO
Property), the applicable Loan-Specific Class Representative (in the case of a
Split Trust Mortgage


                                     -196-



Loan or any related REO Property), or the Controlling Class Representative (in
all other cases involving a Serviced Mortgage Loan or an Administered REO
Property and, if an STML Change of Control Event exists with respect thereto, in
the case of a Split Trust Mortgage Loan or any related REO Property), as
applicable, may, at its own expense, obtain and deliver to the Master Servicer,
the Special Servicer and the Trustee an appraisal that is reasonably
satisfactory to the Special Servicer and satisfies the requirements of a
"Required Appraisal", and upon the written request of the related Serviced Loan
Combination Controlling Party, a Loan-Specific Class Representative or the
Controlling Class Representative, as applicable, the Special Servicer shall
recalculate the Appraisal Reduction Amount in respect of the subject Required
Appraisal Loan based on such appraisal delivered by such party and shall notify
the Trustee, the Master Servicer, the Controlling Class Representative and, in
the case of a Serviced Loan Combination, the related Serviced Loan Combination
Controlling Party and, in the case of a Split Trust Mortgage Loan or related REO
Property, the applicable Loan-Specific Class Representative, of such
recalculated Appraisal Reduction Amount.

          (b) Notwithstanding any other provision of this Agreement, no
Mortgaged Property shall be acquired by the Special Servicer on behalf of the
Certificateholders (and, in the case of a Mortgaged Property that secures a
Serviced Loan Combination, the related Serviced Non-Trust Mortgage Loan
Noteholder(s)) under such circumstances, in such manner or pursuant to such
terms as would, in the reasonable, good faith judgment of the Special Servicer
(exercised in accordance with the Servicing Standard), (i) cause such Mortgaged
Property to fail to qualify as "foreclosure property" within the meaning of
Section 860G(a)(8) of the Code (unless the portion of such Mortgaged Property
that is not treated as "foreclosure property" and that is held by a REMIC Pool
at any given time constitutes not more than a de minimis amount of the assets of
such REMIC Pool within the meaning of Treasury regulations section
1.860D-1(b)(3)(i) and (ii)), or (ii) except as permitted by Section 3.17(a),
subject the Trust Fund to the imposition of any federal income taxes under the
Code. Subject to the foregoing, however, a Mortgaged Property may be acquired
through a single member limited liability company if the Special Servicer
determines that such an action is appropriate to protect the Trust (and, in the
case of a Mortgaged Property that secures a Serviced Loan Combination, the
related Non-Trust Mortgage Loan Noteholder(s)) from potential liability.

          In addition, the Special Servicer shall not acquire any personal
property pursuant to this Section 3.09 unless either:

               (i) such personal property is, in the reasonable, good faith
     judgment of the Special Servicer (exercised in accordance with the
     Servicing Standard), incident to real property (within the meaning of
     Section 856(e)(1) of the Code) so acquired by the Special Servicer; or

               (ii) the Special Servicer shall have obtained an Opinion of
     Counsel (the cost of which shall be covered by, and be reimbursable as, a
     Servicing Advance) to the effect that the holding of such personal property
     as part of the Trust Fund will not cause the imposition of a tax on any
     REMIC Pool under the REMIC Provisions or cause any REMIC Pool to fail to
     qualify as a REMIC at any time that any Certificate is outstanding.

          (c) Notwithstanding the foregoing provisions of this Section 3.09,
neither the Master Servicer nor the Special Servicer shall, on behalf of the
Trustee (and, in the case of a Mortgaged Property that secures a Serviced Loan
Combination, on behalf of the related Serviced Non-Trust Mortgage Loan
Noteholder(s)), obtain title to a Mortgaged Property by foreclosure, deed in
lieu of


                                     -197-



foreclosure or otherwise, or take any other action with respect to any Mortgaged
Property, if, as a result of any such action, the Trustee, on behalf of the
Certificateholders (and, in the case of a Mortgaged Property that secures a
Serviced Loan Combination, on behalf of the related Serviced Non-Trust Mortgage
Loan Noteholder(s)), could, in the reasonable, good faith judgment of the
Special Servicer, exercised in accordance with the Servicing Standard, be
considered to hold title to, to be a "mortgagee-in-possession" of, or to be an
"owner" or "operator" of such Mortgaged Property within the meaning of CERCLA or
any comparable law (a "potentially responsible party"), unless such action is
consistent with Section 6.11 and/or Section 6.12, in each case if and as
applicable, and the Special Servicer has previously determined (as evidenced by
an Officer's Certificate to such effect delivered to the Trustee (and, in the
case of a Mortgaged Property that secures a Serviced Loan Combination, to the
related Serviced Non-Trust Mortgage Loan Noteholder(s)) that shall specify all
of the bases for such determination), in accordance with the Servicing Standard
and based on an Environmental Assessment of such Mortgaged Property performed by
an Independent Person, who regularly conducts Environmental Assessments, within
six months prior to any such acquisition of title or other action (a copy of
which Environmental Assessment shall be delivered to the Trustee, the Master
Servicer and, in the case of a Mortgaged Property that secures a Serviced Loan
Combination, on behalf of the related Serviced Non-Trust Mortgage Loan
Noteholder(s)), that:

               (i) the Mortgaged Property is in compliance with applicable
     environmental laws and regulations or, if not, that it would (taking into
     account the coverage provided under any related Environmental Insurance
     Policy) maximize the recovery on the related Serviced Mortgage Loan to the
     Certificateholders (or, if a Serviced Loan Combination is involved, to the
     Certificateholders and the related Serviced Non-Trust Mortgage Loan
     Noteholder(s)), as a collective whole, on a present value basis (the
     relevant discounting of anticipated collections that will be distributable
     to Certificateholders (or, if a Serviced Loan Combination is involved, to
     the Certificateholders and the related Serviced Non-Trust Mortgage Loan
     Noteholder(s)), as a collective whole, to be performed at the related
     Mortgage Rate(s)) to acquire title to or possession of the Mortgaged
     Property and to take such actions as are necessary to bring the Mortgaged
     Property into compliance therewith in all material respects; and

               (ii) there are no circumstances or conditions present at the
     Mortgaged Property relating to the use, management or disposal of Hazardous
     Materials for which investigation, testing, monitoring, containment,
     clean-up or remediation could be required under any applicable
     environmental laws and regulations or, if such circumstances or conditions
     are present for which any such action could reasonably be expected to be
     required, that it would (taking into account the coverage provided under
     any related Environmental Insurance Policy) maximize the recovery on the
     related Serviced Mortgage Loan to the Certificateholders (or, if a Serviced
     Loan Combination is involved, to the Certificateholders and the related
     Serviced Non-Trust Mortgage Loan Noteholder(s)), as a collective whole, on
     a present value basis (the relevant discounting of anticipated collections
     that will be distributable to Certificateholders (or, if a Serviced Loan
     Combination is involved, to the Certificateholders and the related Serviced
     Non-Trust Mortgage Loan Noteholder(s)), as a collective whole, to be
     performed at the related Mortgage Rate(s)) to acquire title to or
     possession of the Mortgaged Property and to take such actions with respect
     to the affected Mortgaged Property.

          The Special Servicer shall, in good faith, undertake reasonable
efforts to make the determination referred to in the preceding paragraph and may
conclusively rely on the Environmental


                                     -198-



Assessment referred to above in making such determination. The cost of any such
Environmental Assessment shall be covered by, and reimbursable as, a Servicing
Advance; and if any such Environmental Assessment so warrants, the Special
Servicer shall perform or cause to be performed such additional environmental
testing as it deems necessary and prudent to determine whether the conditions
described in clauses (i) and (ii) of the preceding paragraph have been satisfied
(the cost of any such additional testing also to be covered by, and reimbursable
as, a Servicing Advance). The cost of any remedial, corrective or other further
action contemplated by clause (i) and/or clause (ii) of the preceding paragraph,
shall be payable out of the related Custodial Account pursuant to Section
3.05(a) or Section 3.05A, as applicable (or, in the case of a Mortgaged Property
that secures a Serviced Loan Combination, to the extent the funds in the
applicable Loan Combination Custodial Account are insufficient, shall be
advanced by the Master Servicer, subject to Section 3.11(h)).

          (d) If the environmental testing contemplated by Section 3.09(c) above
establishes that any of the conditions set forth in clauses (i) and (ii) of the
first sentence thereof has not been satisfied with respect to any Mortgaged
Property securing a defaulted Serviced Mortgage Loan, the Special Servicer shall
take such action as is in accordance with the Servicing Standard (other than
proceeding against the Mortgaged Property). At such time as it deems
appropriate, the Special Servicer may, on behalf of the Trust (and, if a
Serviced Loan Combination is involved, the related Serviced Non-Trust Mortgage
Loan Noteholder(s)), subject to Section 6.11 and/or Section 6.12, in each case
if and as applicable, release all or a portion of such Mortgaged Property from
the lien of the related Mortgage.

          (e) The Special Servicer shall report to the Master Servicer, the
Underwriters, the Trustee and, if a Serviced Loan Combination is involved, the
related Serviced Non-Trust Mortgage Loan Noteholder(s), monthly in writing as to
any actions taken by the Special Servicer with respect to any Mortgaged Property
that represents security for a Specially Serviced Mortgage Loan as to which the
environmental testing contemplated in Section 3.09(c) above has revealed that
any of the conditions set forth in clauses (i) and (ii) of the first sentence
thereof has not been satisfied, in each case until the earlier to occur of
satisfaction of all such conditions and release of the lien of the related
Mortgage on such Mortgaged Property.

          (f) The Special Servicer shall have the right to determine, in
accordance with the Servicing Standard, with respect to any Specially Serviced
Mortgage Loan, the advisability of seeking to obtain a deficiency judgment if
the state in which the related Mortgaged Property is located and the terms of
the affected Serviced Mortgage Loan permit such an action, and shall, in
accordance with the Servicing Standard, seek such deficiency judgment if it
deems advisable (the cost of which undertaking shall be covered by, and be
reimbursable as, a Servicing Advance).

          (g) The Master Servicer shall, with the reasonable cooperation of the
Special Servicer, prepare and file information returns with respect to the
receipt of mortgage interest received with respect to any Serviced Mortgage Loan
required by Section 6050H of the Code and the reports of foreclosures and
abandonments of any Mortgaged Property (other than any Mortgaged Property that
secures an Outside Serviced Trust Mortgage Loan) and the information returns
relating to cancellation of indebtedness income with respect to any Mortgaged
Property required by Sections 6050J and 6050P of the Code. Such reports shall be
in form and substance sufficient to meet the reporting requirements imposed by
Sections 6050H, 6050J and 6050P of the Code.


                                     -199-



          (h) As soon as the Special Servicer makes a Final Recovery
Determination with respect to any Specially Serviced Mortgage Loan or
Administered REO Property, it shall promptly notify the Trustee, the Master
Servicer and, if a Serviced Loan Combination is involved, the related Serviced
Non-Trust Mortgage Loan Noteholder(s). The Special Servicer shall maintain
accurate records, prepared by a Servicing Officer, of each such Final Recovery
Determination (if any) and the basis thereof. Each such Final Recovery
Determination (if any) shall be evidenced by an Officer's Certificate delivered
to the Trustee, the Master Servicer and, if a Serviced Loan Combination is
involved, the related Serviced Non-Trust Mortgage Loan Noteholder(s), no later
than the seventh Business Day following such Final Recovery Determination.

          SECTION 3.10.  Trustee and Custodian to Cooperate; Release of Mortgage
                         Files.

          (a) Upon the payment in full of any Serviced Mortgage Loan, or the
receipt by the Master Servicer or the Special Servicer of a notification that
payment in full shall be escrowed in a manner customary for such purposes, the
Master Servicer or the Special Servicer shall promptly notify the Trustee and
any related Custodian (and, in the case of a Serviced Non-Trust Mortgage Loan,
the related Serviced Non-Trust Mortgage Loan Noteholder) by a certification
(which certification shall be in the form of a Request for Release in the form
of Exhibit D-1 attached hereto and shall be accompanied by the form of a release
or discharge and shall include a statement to the effect that all amounts
received or to be received in connection with such payment which are required to
be deposited in the applicable Custodial Account pursuant to Section 3.04(a) or
Section 3.04A(a), as applicable, have been or will be so deposited) of a
Servicing Officer (a copy of which certification shall be delivered to the
Special Servicer) and shall request delivery to it of the related Mortgage File
and, in the case of a Serviced Non-Trust Mortgage Loan, the original of the
Mortgage Note for such Serviced Non-Trust Mortgage Loan. Upon receipt of such
certification and request, the Trustee shall release, or cause any related
Custodian to release, the related Mortgage File (and, in the case of a Serviced
Non-Trust Mortgage Loan, the Trustee shall cause the related Serviced Non-Trust
Mortgage Loan Noteholder to release the Mortgage Note for such Serviced
Non-Trust Mortgage Loan) to the Master Servicer or Special Servicer and shall
deliver to the Master Servicer or Special Servicer, as applicable, such release
or discharge, duly executed. No expenses incurred in connection with any
instrument of satisfaction or deed of reconveyance shall be chargeable to the
Collection Account or any Custodial Account.

          (b) If from time to time, and as appropriate for servicing or
foreclosure of any Serviced Mortgage Loan, the Master Servicer or the Special
Servicer shall otherwise require any Mortgage File (or any portion thereof) (or
the original of the Mortgage Note for a Serviced Non-Trust Mortgage Loan), the
Trustee, upon request of the Master Servicer and receipt from the Master
Servicer of a Request for Release in the form of Exhibit D-1 attached hereto
signed by a Servicing Officer thereof, or upon request of the Special Servicer
and receipt from the Special Servicer of a Request for Release in the form of
Exhibit D-2 attached hereto, shall release, or cause any related Custodian to
release, such Mortgage File (or such portion thereof) (and, in the case of a
Serviced Non-Trust Mortgage Loan, the Trustee shall cause the related Serviced
Non-Trust Mortgage Loan Noteholder to release the original of the Mortgage Note
for such Non-Trust Mortgage Loan) to the Master Servicer or the Special
Servicer, as the case may be. Upon return of such Mortgage File (or such portion
thereof) to the Trustee or related Custodian (and, if applicable, such original
Mortgage Note for such Serviced Non-Trust Mortgage Loan to the related Serviced
Non-Trust Mortgage Loan Noteholder), or the delivery to the Trustee (and, if
applicable, to the related Serviced Non-Trust Mortgage Loan Noteholder) of a
certificate of a Servicing Officer of the Special Servicer stating that such
Serviced Mortgage Loan was liquidated


                                     -200-



and that all amounts received or to be received in connection with such
liquidation that are required to be deposited into the related Custodial Account
pursuant to Section 3.04(a) or Section 3.04A(a), as applicable, have been or
will be so deposited, or that the related Mortgaged Property has become an REO
Property, the Request for Release shall be released by the Trustee or related
Custodian to the Master Servicer or the Special Servicer, as applicable. If the
Master Servicer or the Special Servicer requires the original Mortgage Note or
any other document that constitutes part of a Mortgage File for any Trust
Mortgage Loan, then (unless such document is to be delivered to outside legal
counsel) such documents shall be maintained in a manner consistent with the
Servicing Standard.

          (c) Within seven (7) Business Days (or within such shorter period (but
no less than three (3) Business Days) as execution and delivery can reasonably
be accomplished if the Special Servicer notifies the Trustee (and, in the case
of a Serviced Loan Combination, the related Serviced Non-Trust Mortgage Loan
Noteholder(s)) of an exigency) of the Special Servicer's request therefor, the
Trustee shall execute and deliver to the Special Servicer (or the Special
Servicer may execute and deliver in the name of the Trustee (on behalf of the
Certificateholders and, in the case of a Mortgaged Property that secures a
Serviced Loan Combination, the related Serviced Non-Trust Mortgage Loan
Noteholder(s)) based on a limited power of attorney issued in favor of the
Special Servicer pursuant to Section 3.01(b)), in the form supplied to the
Trustee, with respect to any Serviced Mortgage Loan, any court pleadings,
requests for trustee's sale or other documents stated by the Special Servicer to
be reasonably necessary to the foreclosure or trustee's sale in respect of the
related Mortgaged Property or to any legal action brought to obtain judgment
against any Mortgagor on the related Mortgage Note or Mortgage or to obtain a
deficiency judgment, or to enforce any other remedies or rights provided by the
related Mortgage Note or Mortgage or otherwise available at law or in equity or
to defend any legal action or counterclaim filed against the Trust Fund, the
Master Servicer, the Special Servicer or, if applicable, any Serviced Non-Trust
Mortgage Loan Noteholder. Together with such documents or pleadings, the Special
Servicer shall deliver to the Trustee (and, if applicable, any affected Serviced
Non-Trust Mortgage Loan Noteholder) a certificate of a Servicing Officer
requesting that such pleadings or documents be executed by the Trustee and
certifying as to the reason such documents or pleadings are required and that
the execution and delivery thereof by the Trustee (on behalf of the
Certificateholders and, in the case of a Serviced Loan Combination, also on
behalf of the related Serviced Non-Trust Mortgage Loan Noteholder(s)) will not
invalidate or otherwise affect the lien of the Mortgage, except for the
termination of such a lien upon completion of the foreclosure or trustee's sale.
Notwithstanding anything contained herein to the contrary, neither the Master
Servicer nor the Special Servicer shall, without the Trustee's written consent:
(i) initiate any action, suit or proceeding solely under the Trustee's name
without indicating the Master Servicer's or Special Servicer's, as applicable,
representative capacity, or (ii) take any action with the intent to cause, and
that actually causes, the Trustee to be registered to do business in any state.

          (d) If from time to time, pursuant to the terms of the related
Co-Lender Agreement and the related Outside Servicing Agreement, and as
appropriate for enforcing the terms of any Outside Serviced Trust Mortgage Loan,
any related Outside Servicer or the appropriate Non-Trust Mortgage Loan
Noteholder requests delivery to it of the original Mortgage Note for such
Outside Serviced Trust Mortgage Loan, then the Trustee shall release or cause
the release of such original Mortgage Note to the requesting party or its
designee. In connection with the release of the original Mortgage Note for any
Outside Serviced Trust Mortgage Loan in accordance with the preceding sentence,
the Trustee shall obtain such documentation (such as a custodial receipt) as is
appropriate to evidence the holding by the


                                     -201-



related Outside Servicer or the appropriate Non-Trust Mortgage Loan Noteholder
as custodian on behalf of and for the benefit of the Trustee.

          SECTION 3.11.  Servicing Compensation; Payment of Expenses; Certain
                         Matters Regarding Servicing Advances.

          (a) As compensation for its activities hereunder, the Master Servicer
shall be entitled to receive the Master Servicing Fee with respect to each Trust
Mortgage Loan, each REO Trust Mortgage Loan, each Serviced Non-Trust Mortgage
Loan and any successor REO Mortgage Loan with respect to a Serviced Non-Trust
Mortgage Loan. As to each such Mortgage Loan and REO Mortgage Loan, the Master
Servicing Fee shall: (i) accrue from time to time at the related Master
Servicing Fee Rate on the same principal amount as interest accrues from time to
time on such Mortgage Loan or is deemed to accrue from time to time on such REO
Mortgage Loan; and (ii) be calculated on a 30/360 Basis (or, in the event that a
Principal Prepayment in full or other Liquidation Event shall occur with respect
to any such Mortgage Loan or REO Mortgage Loan on a date that is not a Due Date,
on the basis of the actual number of days to elapse from and including the most
recently preceding related Due Date to but excluding the date of such Principal
Prepayment or Liquidation Event in a month consisting of 30 days). The Master
Servicing Fee with respect to any such Mortgage Loan or REO Mortgage Loan shall
cease to accrue if a Liquidation Event occurs in respect thereof. Earned but
unpaid Master Servicing Fees shall be payable monthly, on a loan-by-loan basis,
from payments of interest on each such Mortgage Loan and REO Revenues allocable
as interest on each such REO Mortgage Loan. The Master Servicer shall be
entitled to recover unpaid Master Servicing Fees in respect of any such Mortgage
Loan or REO Mortgage Loan out of that portion of related Insurance Proceeds,
Condemnation Proceeds or Liquidation Proceeds allocable as recoveries of
interest, to the extent permitted by Section 3.05(a) or Section 3.05A, as
applicable, and in the case of a Trust Mortgage Loan or an REO Trust Mortgage
Loan, out of such other amounts as may be permitted by Section 3.05(a). The
right to receive the Master Servicing Fee may not be transferred in whole or in
part except in connection with the transfer of all of the Master Servicer's
responsibilities and obligations under this Agreement.

          (b) Additional master servicing compensation, in the form of the items
set forth in clauses (i) through (iii) below in this paragraph, shall be
retained by the Master Servicer or promptly paid to the Master Servicer by the
Special Servicer and such additional master servicing compensation is not
required to be deposited in any Custodial Account: (i) Net Default Charges,
charges for beneficiary statements or demands, amounts collected for checks
returned for insufficient funds, and any similar fees (excluding Prepayment
Premiums and Yield Maintenance Charges), in each case to the extent actually
paid by a Mortgagor with respect to any Serviced Mortgage Loan (or, in the case
of Net Default Charges, any Serviced Trust Mortgage Loan) and accrued during the
time that such Serviced Mortgage Loan (or, in the case of Net Default Charges,
such Serviced Trust Mortgage Loan) was a Performing Serviced Mortgage Loan (or,
in the case of Net Default Charges, a Performing Serviced Trust Mortgage Loan),
and any Net Default Charges Received by the Trust with respect to an Outside
Serviced Trust Mortgage Loan; (ii) 100% (or, if the consent of the Special
Servicer is required with respect to the subject action, 50%) of each
modification fee, extension fee or other similar fee actually paid by a
Mortgagor with respect to a modification, consent, extension, waiver, amendment
or encumbrance of the related Mortgaged Property agreed to by the Master
Servicer pursuant to Section 3.20(c) or Section 3.08(c), and 100% of any fee
actually paid by a Mortgagor in connection with a defeasance of a Serviced
Mortgage Loan as contemplated under Section 3.20; and (iii) with respect to any
Performing Serviced Mortgage Loan, 50% of any and all assumption fees, 100% of
any and all assumption


                                     -202-



application fees (or, in the event that (x) the Master Servicer enters into an
assumption or substitution agreement pursuant to Section 3.08(a) and the related
loan documents do not provide for an assumption fee in connection therewith, or
(y) the proposed transfer or assumption under Section 3.08(a) is approved and/or
processed but does not occur or (z) the proposed transfer or assumption under
Section 3.08(a) is not approved or is denied and does not occur and,
additionally, in the case of (x), (y) and (z), assumption application fees are
paid by the Mortgagor in connection therewith, then 50% of such assumption
application fees) and other applicable fees actually paid by a Mortgagor in
accordance with the related loan documents with respect to any assumption or
substitution agreement entered into by the Master Servicer on behalf of the
Trust (or, in the case of a Serviced Loan Combination, on behalf of the Trust
and the related Non-Trust Mortgage Loan Noteholder(s)) pursuant to Section
3.08(a) or paid by a Mortgagor with respect to any transfer of an interest in a
Mortgagor pursuant to Section 3.08(a). The Master Servicer shall also be
entitled to additional master servicing compensation in the form of (i)
Prepayment Interest Excesses Received by the Trust with respect to the Trust
Mortgage Loans; (ii) interest or other income earned on deposits in the
Custodial Accounts in accordance with Section 3.06(b) (but only to the extent of
the Net Investment Earnings, if any, with respect to such account for each
related Investment Period); and (iii) to the extent not required to be paid to
any Mortgagor under applicable law, any interest or other income earned on
deposits in the Servicing Accounts, the Reserve Accounts and the Defeasance
Deposit Account maintained thereby (but only to the extent of the Net Investment
Earnings, if any, with respect to each such account for each related Investment
Period).

          The parties hereto acknowledge that, with regard to each Outside
Serviced Trust Mortgage Loan, as and to the extent provided in the related
Outside Servicing Agreement and/or the related Co-Lender Agreement, as
applicable, amounts in the nature of the foregoing may be payable to one of the
related Outside Servicers, and there can be no assurance that any related
Prepayment Interest Excesses and/or Default Charges shall be Received by the
Trust with respect to an Outside Serviced Trust Mortgage Loan.

          (c) As compensation for its activities hereunder, the Special Servicer
shall be entitled to receive the Special Servicing Fee with respect to each
Specially Serviced Mortgage Loan and each REO Mortgage Loan that relates to an
Administered REO Property. With respect to each Specially Serviced Mortgage Loan
and each REO Mortgage Loan that relates to an Administered REO Property, the
Special Servicing Fee shall: (i) accrue from time to time at the Special
Servicing Fee Rate on the same principal amount as interest accrues from time to
time on such Mortgage Loan or is deemed to accrue from time to time on such REO
Mortgage Loan; and (ii) be calculated on a 30/360 Basis (or, in the event that a
Principal Prepayment in full or other Liquidation Event shall occur with respect
to any Specially Serviced Mortgage Loan or REO Mortgage Loan on a date that is
not a Due Date, on the basis of the actual number of days to elapse from and
including the most recently preceding related Due Date to but excluding the date
of such Principal Prepayment or Liquidation Event, in a month consisting of 30
days and, in the case of any other partial period that does not run from one Due
Date through and including the day immediately preceding the next Due Date, on
the basis of the actual number of days in such period in a month consisting of
30 days). The Special Servicing Fee with respect to any Specially Serviced
Mortgage Loan or REO Mortgage Loan shall cease to accrue as of the date a
Liquidation Event occurs in respect thereof or it becomes a Corrected Mortgage
Loan. Earned but unpaid Special Servicing Fees in respect of Specially Serviced
Trust Mortgage Loans and, to the extent they relate to Administered REO
Properties, REO Trust Mortgage Loans shall be payable monthly out of general
collections on the Mortgage Pool on deposit in the Pool Custodial Account, to
the extent permitted by Section 3.05(a). In addition, earned but unpaid Special
Servicing Fees in respect of a Serviced Loan


                                     -203-



Combination consisting of Specially Serviced Mortgage Loans or REO Mortgage
Loans shall be payable out of collections on such Loan Combination on deposit in
the applicable Loan Combination Custodial Account, to the extent permitted
pursuant to Section 3.05A and the related Co-Lender Agreement, and, with respect
to any Serviced Combination Trust Mortgage Loan that constitutes a Specially
Serviced Mortgage Loan or REO Mortgage Loan, out of collections on deposit in
the Pool Custodial Account, to the extent permitted pursuant to Section 3.05.

          As further compensation for its services hereunder, the Special
Servicer shall be entitled to receive the Workout Fee with respect to each
Corrected Mortgage Loan. As to each Corrected Mortgage Loan, subject to the
second following paragraph, the Workout Fee shall be payable from, and shall be
calculated by application of the Workout Fee Rate to, all collections of
principal, interest (other than any Default Interest, Additional Interest and
Excess Defeasance Deposit Proceeds), Prepayment Premiums and/or Yield
Maintenance Charges received on the subject Serviced Mortgage Loan for so long
as it remains a Corrected Mortgage Loan; provided that no Workout Fee shall be
payable from, or based upon the receipt of, Liquidation Proceeds collected in
connection with a Permitted Purchase, or out of any Loss of Value Payments,
Insurance Proceeds or Condemnation Proceeds. The Workout Fee with respect to any
Corrected Mortgage Loan will cease to be payable if such Corrected Mortgage Loan
again becomes a Specially Serviced Mortgage Loan or if the related Mortgaged
Property becomes an REO Property; provided that a new Workout Fee will become
payable if and when the particular Serviced Mortgage Loan again becomes a
Corrected Mortgage Loan. If the Special Servicer is terminated or removed (other
than for cause) or resigns in accordance with the first sentence of the first
paragraph of Section 6.04, it shall retain the right to receive any and all
Workout Fees (and the successor Special Servicer (including the Trustee if it is
the successor Special Servicer as provided in the first paragraph of Section
7.02) shall not be entitled to any portion of such Workout Fees) that are
payable in respect of:

               (i) each Mortgage Loan that became a Corrected Mortgage Loan
     during the period that the terminated, removed or resigning Special
     Servicer acted as Special Servicer and was still such at the time of such
     termination, removal or resignation; and

               (ii) each Mortgage Loan that would have been a "Corrected
     Mortgage Loan" at the time of such termination, removal or resignation but
     for the payment (in accordance with clause (w) of the definition of
     "Specially Serviced Mortgage Loan") by the related Mortgagor of the three
     consecutive full and timely Monthly Payments under the terms of such
     Serviced Mortgage Loan (as such terms may have been changed or modified in
     connection with a bankruptcy or similar proceeding involving the related
     Mortgagor or by reason of a modification, extension, waiver or amendment
     granted or agreed to by the Master Servicer or the Special Servicer
     pursuant to Section 3.20), but only if such three consecutive full and
     timely Monthly Payments are in fact made within three months of such
     termination, removal or resignation;

in each case until the Workout Fee for any such Serviced Mortgage Loan ceases to
be payable in accordance with the preceding sentence.

          As further compensation for its activities hereunder, the Special
Servicer shall also be entitled to receive the Liquidation Fee with respect to
each Specially Serviced Mortgage Loan as to which it receives a full, partial or
discounted payoff and, subject to the provisos to the next sentence,


                                     -204-



each Specially Serviced Mortgage Loan and Administered REO Property as to which
it receives Net Liquidation Proceeds. As to each such Specially Serviced
Mortgage Loan or Administered REO Property, subject to the following paragraph,
the Liquidation Fee shall be payable from, and shall be calculated by
application of the Liquidation Fee Rate to, such full, partial or discounted
payoff and/or such Net Liquidation Proceeds (exclusive of any portion of such
payoff or proceeds that represents Default Interest and/or Additional Interest);
provided that no Liquidation Fee shall be payable (i) with respect to any
Specially Serviced Mortgage Loan that becomes a Corrected Mortgage Loan or (ii)
from, or based upon the receipt of, Liquidation Proceeds collected in connection
with the acquisition of any Specially Serviced Mortgage Loan or REO Property by
all the Certificateholders (acting together) in exchange for all the
Certificates pursuant to Section 9.01 or the purchase of any Specially Serviced
Trust Mortgage Loan by a Purchase Option Holder pursuant to Section 3.18
(provided, however, that a Liquidation Fee will be paid in connection with the
purchase of a Specially Serviced Trust Mortgage Loan at its FV Price as
determined in Section 3.18, if such purchase is by an assignee of either a
Holder of a Certificate of the Controlling Class or the Special Servicer, such
assignee is not an Affiliate of a Holder of a Certificate of the Controlling
Class or the Special Servicer, such assignment is for no material consideration,
and such purchase occurs or purchase right is exercised more than 90 days from
the date that the Special Servicer has initially determined the FV Price of the
related Mortgage Loan), by the Special Servicer, a Controlling Class
Certificateholder, the Master Servicer, the Depositor or Lehman Brothers
pursuant to Section 9.01, by a Non-Trust Mortgage Loan Noteholder or its
designee pursuant to the related Co-Lender Agreement (unless such purchase
occurs after the expiration of 60 days from the date such Non-Trust Mortgage
Loan Noteholder's right to purchase such Specially Serviced Trust Mortgage Loan
arose under such Co-Lender Agreement and such Liquidation Fee is actually paid),
by a Loan-Specific Class Representative pursuant to Section 3.27 (unless such
purchase occurs after the expiration of 90 days from the date such Loan-Specific
Class Representative's right to purchase such Specially Designated Trust
Mortgage Loan arose hereunder and such Liquidation Fee is actually paid), by the
Depositor pursuant to Section 2.03 or by or on behalf of the UBS Mortgage Loan
Seller pursuant to the UBS/Depositor Mortgage Loan Purchase Agreement in
connection with a Material Document Defect or a Material Breach (in either such
case, prior to the expiration of the Seller/Depositor Resolution Period), by the
Depositor pursuant to Section 2.03 or by or on behalf of the UBS Mortgage Loan
Seller pursuant to the UBS/Depositor Mortgage Loan Purchase Agreement in
connection with the defeasance of an Early Defeasance Trust Mortgage Loan prior
to the second anniversary of the Closing Date, or by the holder of a related
mezzanine loan pursuant to a purchase right in connection with a Mortgage Loan
default as set forth in the related intercreditor agreement (unless a
Liquidation Fee is specifically required to be paid in connection with such
purchase and is actually paid pursuant to the subject intercreditor agreement;
provided that, if the Master Servicer or Special Servicer, as applicable,
consents subsequent to the Closing Date to the incurrence by the principal(s) of
a Mortgagor under a Trust Mortgage Loan of mezzanine financing in accordance
with the related loan documents and enters into an intercreditor agreement, such
servicer (to the extent it is permitted to do so under the related loan
documents and applicable law and in accordance with the Servicing Standard)
shall require the related mezzanine lender to pay a Liquidation Fee in
connection with any purchase right that arises upon a Mortgage Loan default in
the event such purchase occurs after the expiration of 60 days from the date the
right to purchase arises under such mezzanine intercreditor agreement) or (iii)
from, or based upon the receipt or application of, Loss of Value Payments; and
provided, further, that, in connection with any purchase by the Depositor
pursuant to Section 2.03 or the UBS Mortgage Loan Seller pursuant to the
UBS/Depositor Mortgage Loan Purchase Agreement in connection with a Material
Document Defect or a Material Breach (in either case, subsequent to the
expiration of the Seller/Depositor Resolution Period), the Liquidation Fee shall
equal 1% of the Stated


                                     -205-



Principal Balance of the repurchased Trust Mortgage Loan (or, if an REO Property
is being repurchased, 1% of the Stated Principal Balance of the related REO
Trust Mortgage Loan).

          Notwithstanding the foregoing, any Workout Fee and/or Liquidation Fee
payable in accordance with the two preceding paragraphs with respect to Mortgage
Loans or REO Mortgage Loans that comprise a Serviced Loan Combination shall be
paid from collections received on such Loan Combination on deposit in the
applicable Loan Combination Custodial Account, to the extent permitted pursuant
to Section 3.05A and the related Co-Lender Agreement.

          Notwithstanding anything to the contrary herein, a Liquidation Fee and
a Workout Fee relating to the same Mortgage Loan shall not be paid from the same
proceeds with respect to such Mortgage Loan.

          Notwithstanding anything to the contrary herein, the Special Servicer
shall not be entitled to any Special Servicing Fees, Workout Fees or Liquidation
Fees with respect to any Mortgage Loan or REO Mortgage Loan or comparable deemed
mortgage loan comprising an Outside Serviced Loan Combination.

          The Special Servicer's right to receive the Special Servicing Fee, the
Workout Fee and the Liquidation Fee may not be transferred in whole or in part
except in connection with the transfer of all of the Special Servicer's
responsibilities and obligations under this Agreement.

          (d) Additional special servicing compensation in the form of the items
set forth below in clauses (i) through (v) below shall be retained by the
Special Servicer or promptly paid to the Special Servicer by the Master
Servicer, as the case may be, and shall not be required to be deposited in any
Custodial Account pursuant to Section 3.04(a) or Section 3.04A(a): (i) Net
Default Charges actually collected with respect to any Serviced Trust Mortgage
Loan or any successor REO Trust Mortgage Loan with respect thereto that accrued
while the subject loan was a Specially Serviced Trust Mortgage Loan or an REO
Trust Mortgage Loan; (ii) with respect to any Specially Serviced Mortgage Loan,
100% of any and all assumption fees, assumption application fees and other
applicable fees, actually paid by a Mortgagor in accordance with the related
loan documents, with respect to any assumption or substitution agreement entered
into by the Special Servicer on behalf of the Trust (or, in the case of a
Serviced Loan Combination, on behalf of the Trust and the related Serviced
Non-Trust Mortgage Loan Noteholder(s)) pursuant to Section 3.08(b) or paid by a
Mortgagor with respect to any transfer of an interest in a Mortgagor pursuant to
Section 3.08(b); (iii) with respect to any Performing Serviced Mortgage Loan,
50% of any and all assumption fees actually paid by a Mortgagor in accordance
with the related loan documents, with respect to any assumption or substitution
agreement entered into by the Master Servicer on behalf of the Trust (or, in the
case of a Serviced Loan Combination, on behalf of the Trust and the related
Serviced Non-Trust Mortgage Loan Noteholder(s)) pursuant to Section 3.08(a) or
paid by a Mortgagor with respect to any transfer of an interest in a Mortgagor
pursuant to Section 3.08(a); (iv) with respect to any Performing Serviced
Mortgage Loan, in the event that (x) the Master Servicer enters into an
assumption or substitution agreement pursuant to Section 3.08(a) and the related
loan documents do not provide for an assumption fee in connection therewith or
(y) the proposed transfer or assumption under Section 3.08(a) is approved and/or
processed but does not occur or (z) the proposed transfer or assumption under
Section 3.08(a) is not approved or is denied and does not occur and,
additionally, in the case of (x), (y) and (z), assumption application fees are
paid by the Mortgagor in connection therewith, then 50% of such assumption
application fees; (v) with respect to any Performing


                                     -206-



Serviced Mortgage Loan, if the consent of the Special Servicer is required with
respect to the subject action, 50% of each modification fee, extension fee or
other similar fee actually paid by a Mortgagor with respect to a modification,
consent, extension, waiver, amendment or encumbrance of the related Mortgaged
Property agreed to by the Master Servicer pursuant to Section 3.20(c) or Section
3.08(c); and (vi) any and all other modification fees, consent fees, extension
fees and similar fees actually collected on the Serviced Mortgage Loans that are
not otherwise payable to the Master Servicer as additional master servicing
compensation pursuant to Section 3.11(b). The Special Servicer shall also be
entitled to additional special servicing compensation in the form of interest or
other income earned on deposits in any REO Account, if established, in
accordance with Section 3.06(b) (but only to the extent of the Net Investment
Earnings, if any, with respect to such account for each related Investment
Period).

          (e) The Master Servicer and the Special Servicer shall each be
required to pay out of its own funds all expenses incurred by it in connection
with its servicing activities hereunder (including payment of any amounts due
and owing to any of its Sub-Servicers and the premiums for any blanket policy or
the standby fee or similar premium for any master force placed policy obtained
by it insuring against hazard losses pursuant to Section 3.07(b)), if and to the
extent such expenses are not payable directly out of any of the Custodial
Accounts or, in the case of the Special Servicer, any of the REO Accounts, and
neither the Master Servicer nor the Special Servicer shall be entitled to
reimbursement for such expenses except as expressly provided in this Agreement.

          (f) If the Master Servicer or Special Servicer is required under any
provision of this Agreement to make a Servicing Advance, but it does not do so
within 15 days after such Advance is required to be made, the Trustee shall, if
it has actual knowledge of such failure on the part of the Master Servicer or
Special Servicer, as the case may be, give written notice of such failure to, as
applicable, the Master Servicer or the Special Servicer. If such Servicing
Advance is not made by the Master Servicer or the Special Servicer, as
applicable, within three (3) Business Days after such notice is given to the
Master Servicer or the Special Servicer, as the case may be, then (subject to
Section 3.11(h)) the Trustee shall make such Servicing Advance. If the Trustee
fails to make any Servicing Advance required to be made under this Agreement,
then (subject to Section 3.11(h)) the Fiscal Agent, if any, shall make such
Servicing Advance within one (1) Business Day of such failure by the Trustee
and, if so made, the Trustee shall be deemed not to be in default under this
Agreement.

          (g) The Master Servicer, the Special Servicer, the Trustee and any
Fiscal Agent shall each be entitled to receive interest at the Reimbursement
Rate in effect from time to time, compounded annually, accrued on the amount of
each Servicing Advance made thereby (with its own funds) for so long as such
Servicing Advance is outstanding, such interest to be payable: (i) first, in
accordance with Sections 3.05(a) and 3.26, out of any Default Charges on deposit
in the Pool Custodial Account that were collected on or in respect of the
particular Trust Mortgage Loan or REO Trust Mortgage Loan as to which such
Servicing Advance relates (provided that such Default Charges will only be
applied to pay interest accrued on such Servicing Advance through the date that
such Default Charges were received); and (ii) then, if and to the extent that
such Default Charges are insufficient to cover such interest, but not before the
related Advance has been reimbursed pursuant to this Agreement, out of general
collections on the Trust Mortgage Loans and REO Trust Mortgage Loans on deposit
in the Pool Custodial Account; provided that, if such Servicing Advance was made
with respect to a Serviced Loan Combination or any related Mortgaged Property,
then such interest shall first be payable out of amounts on deposit in the
related Loan Combination Custodial Account in accordance with Section 3.05A and
the related Co-Lender Agreement. The Master Servicer shall reimburse itself, the
Special Servicer, the Trustee or any


                                     -207-



Fiscal Agent, as appropriate, in accordance with Section 3.03, Section 3.05(a)
or Section 3.05A, as applicable, for any Servicing Advance as soon as
practicable after funds available for such purpose are deposited in the
applicable Custodial Account. Notwithstanding the foregoing, upon a
determination that a previously made Servicing Advance is a Nonrecoverable
Servicing Advance, instead of obtaining reimbursement out of general collections
on the Mortgage Pool immediately, any of the Master Servicer, the Special
Servicer, the Trustee or any Fiscal Agent, as applicable, may, in its sole
discretion, elect to obtain reimbursement for such Nonrecoverable Servicing
Advance over a period of time (not to exceed 12 months or such longer period of
time as is approved in writing by the Controlling Class Representative) and the
unreimbursed portion of such Servicing Advance will accrue interest at the
Reimbursement Rate in effect from time to time. At any time after such a
determination to obtain reimbursement over time in accordance with the preceding
sentence, the Master Servicer, the Special Servicer, the Trustee or any Fiscal
Agent, as applicable, may, in its sole discretion, decide to obtain
reimbursement immediately. The fact that a decision to recover such
Nonrecoverable Servicing Advance over time, or not to do so, benefits some
Classes of Certificateholders to the detriment of other Classes shall not
constitute a violation of the Servicing Standard by the Master Servicer, or a
breach of any fiduciary duty owed to the Certificateholders by the Trustee or a
Fiscal Agent, or a breach of any other contractual obligation owed to the
Certificateholders by any party to this Agreement.

          (h) Notwithstanding anything herein to the contrary, none of the
Master Servicer, the Special Servicer, the Trustee or any Fiscal Agent shall be
required to make out of its own funds any Servicing Advance that would, if made,
constitute a Nonrecoverable Servicing Advance. The determination by the Master
Servicer or the Special Servicer that it has made (or, in the case of the
Special Servicer, that the Master Servicer, the Trustee or a Fiscal Agent has
made) a Nonrecoverable Servicing Advance or that any proposed Servicing Advance,
if made, would constitute a Nonrecoverable Servicing Advance, shall be made in
accordance with the Servicing Standard and shall be evidenced by an Officer's
Certificate delivered promptly to the Trustee and the Depositor (and, in the
case of a Servicing Advance with respect to a Serviced Loan Combination, the
related Non-Trust Mortgage Loan Noteholder(s)), setting forth the basis for such
determination, together with a copy of any appraisal of the related Mortgaged
Property or REO Property, as the case may be (which appraisal shall be an
expense of the Trust, shall take into account the factors specified in Section
3.18 and shall have been conducted by an Independent Appraiser in accordance
with the standards of the Appraisal Institute within the twelve months preceding
such determination of nonrecoverability), and further accompanied by related
Mortgagor operating statements and financial statements, budgets and rent rolls
of the related Mortgaged Property (to the extent available and/or in the Master
Servicer's or the Special Servicer's possession) and any engineers' reports,
environmental surveys or similar reports that the Master Servicer or the Special
Servicer may have obtained and that support such determination. If the Master
Servicer intends to obtain an appraisal in connection with the foregoing, the
Master Servicer shall so notify the Special Servicer and consult with the
Special Servicer regarding such appraisal. In determining whether any Servicing
Advance constitutes a Nonrecoverable Servicing Advance, the Master Servicer and
the Special Servicer shall each be entitled to consider (among other things) the
obligations of the related Mortgagor under the terms of the related Mortgage
Loan (as such terms may have been modified), to consider (among other things)
the related Mortgaged Property in its "as is" or then current condition and with
its then current occupancies, all as modified by such party's reasonable
assumptions (consistent with the Servicing Standard) regarding the possibility
and effects of future adverse change with respect to the related Mortgaged
Property, to estimate and consider (among other things) future expenses and to
estimate and consider (among other things) the timing of recoveries. In
addition, the Master Servicer or the Special Servicer may update or change its
recoverability determination at any time with respect to


                                     -208-



any Servicing Advance, and the Master Servicer may obtain from the Special
Servicer any analysis, appraisals or market value estimates or other information
in the possession of the Special Servicer for purposes of determining whether a
Servicing Advance is a Nonrecoverable Servicing Advance. The Trustee and any
Fiscal Agent shall be entitled to rely, conclusively, on any determination by
the Master Servicer (and the Trustee, any Fiscal Agent and the Master Servicer
shall rely on any determination by the Special Servicer) that a Servicing
Advance, if made, would be a Nonrecoverable Servicing Advance; provided,
however, that if the Master Servicer or the Special Servicer has failed to make
a Servicing Advance for reasons other than a determination by the Master
Servicer or the Special Servicer, as applicable, that such Servicing Advance
would be a Nonrecoverable Advance, the Trustee or any Fiscal Agent, as
applicable, shall make such Servicing Advance within the time periods required
by Section 3.11(f) unless the Trustee or such Fiscal Agent, in good faith, makes
a determination that such Servicing Advance would be a Nonrecoverable Advance.

          (i) Notwithstanding anything set forth herein to the contrary, the
Master Servicer shall (at the direction of the Special Servicer if a Specially
Serviced Mortgage Loan or an Administered REO Property is involved) pay directly
out of the Pool Custodial Account and/or (if a Serviced Loan Combination is
involved) the related Loan Combination Custodial Account, in accordance with
Section 3.05(a) or Section 3.05A, as applicable, any servicing expense that, if
advanced by the Master Servicer or the Special Servicer, would constitute a
Nonrecoverable Servicing Advance; provided that the Master Servicer (or the
Special Servicer, if a Specially Serviced Mortgage Loan or an Administered REO
Property is involved) has determined in accordance with the Servicing Standard
that making such payment, in the case of withdrawals from a Loan Combination
Custodial Account, is in the best interests of the Certificateholders and the
related Serviced Non-Trust Mortgage Loan Noteholder (as a collective whole), or,
in the case of withdrawals from the Pool Custodial Account, is in the best
interests of the Certificateholders (as a collective whole), as evidenced in
each case by an Officer's Certificate delivered promptly to the Trustee, the
Depositor, the Controlling Class Representative and any affected Serviced
Non-Trust Mortgage Loan Noteholder(s), setting forth the basis for such
determination and accompanied by any information that such Person may have
obtained that supports such determination. A copy of any such Officer's
Certificate (and accompanying information) of the Master Servicer shall also be
promptly delivered to the Special Servicer, and a copy of any such Officer's
Certificate (and accompanying information) of the Special Servicer shall also be
promptly delivered to the Master Servicer. The Master Servicer may conclusively
rely on any information in this regard provided by the Special Servicer (if
other than the Master Servicer or an Affiliate thereof).

          SECTION 3.12.  Property Inspections; Collection of Financial
                         Statements; Delivery of Certain Reports.

          (a) The Special Servicer shall perform or cause to be performed a
physical inspection of the Mortgaged Property securing a Serviced Mortgage Loan
as soon as practicable after such Serviced Mortgage Loan becomes a Specially
Serviced Mortgage Loan and annually thereafter for so long as such Mortgage Loan
remains a Specially Serviced Mortgage Loan, the cost of which shall be paid by
the Master Servicer, at the direction of the Special Servicer, and shall be
reimbursable as a Servicing Advance. In addition, the Special Servicer shall
perform or cause to be performed a physical inspection of each of the
Administered REO Properties at least once per calendar year, the cost of which
shall be paid by the Master Servicer, at the direction of the Special Servicer,
and shall be reimbursable as a Servicing Advance. Beginning in 2007, the Master
Servicer shall at its expense perform or cause to be performed a physical
inspection of each Mortgaged Property securing a Performing Serviced


                                     -209-



Mortgage Loan: (i) at least once every two calendar years in the case of
Mortgaged Properties securing Performing Serviced Mortgage Loans that have
outstanding principal balances of (or Mortgaged Properties having allocated loan
amounts of) $2,000,000 or less; and (ii) at least once every calendar year in
the case of all other such Mortgaged Properties; provided that, the Master
Servicer will not be required to perform or cause to be performed an inspection
on a Mortgaged Property if such Mortgaged Property has been inspected by the
Master Servicer or the Special Servicer in the preceding six months. The Master
Servicer and the Special Servicer shall each promptly prepare or cause to be
prepared and deliver to the Trustee, the related Serviced Non-Trust Mortgage
Loan Noteholder(s) (if the subject Mortgaged Property secures a Serviced Loan
Combination) and each other a written report of each such inspection performed
by it that sets forth in detail the condition of the Mortgaged Property and that
specifies the existence of: (i) any sale, transfer or abandonment of the
Mortgaged Property of which the Master Servicer or the Special Servicer, as
applicable, is aware, (ii) any change in the condition or value of the Mortgaged
Property that the Master Servicer or the Special Servicer, as applicable, in its
reasonable, good faith judgment, considers material, or (iii) any waste
committed on the Mortgaged Property. The Master Servicer and Special Servicer
shall each forward copies of any such inspection reports prepared by it to the
Underwriters, the Controlling Class Representative and the Serviced Non-Trust
Noteholders, upon request, subject to payment of a reasonable fee.

          The Special Servicer, in the case of each Specially Serviced Mortgage
Loan and each REO Mortgage Loan that relates to an Administered REO Property,
and the Master Servicer, in the case of each Performing Serviced Mortgage Loan,
shall each, consistent with the Servicing Standard, use reasonable efforts to
obtain quarterly, annual and other periodic operating statements and rent rolls
with respect to each of the related Mortgaged Properties and REO Properties. The
Special Servicer shall, promptly following receipt, deliver copies of the
operating statements and rent rolls received or obtained by it to the Master
Servicer. The Master Servicer shall promptly deliver copies of the operating
statements and rent rolls received or obtained by it (including pursuant to the
preceding sentence) to the Trustee, the Special Servicer, any related Serviced
Non-Trust Mortgage Loan Noteholder(s) (if the subject Mortgaged Property secures
a Serviced Loan Combination) or any Controlling Class Certificateholder, in each
case upon request.

          Within 30 days after receipt by the Master Servicer or Special
Servicer, as applicable, of any annual operating statements with respect to any
Mortgaged Property (other than a Mortgaged Property that secures an Outside
Serviced Loan Combination) or Administered REO Property, the Master Servicer
(with respect to a Mortgaged Property that secures a Performing Serviced
Mortgage Loan) and the Special Servicer (with respect to a Mortgaged Property
that secures a Specially Serviced Mortgage Loan or with respect to an
Administered REO Property) shall prepare or update and forward to the Trustee a
CMSA NOI Adjustment Worksheet for such Mortgaged Property or Administered REO
Property (with, upon request, the annual operating statements attached thereto
as an exhibit).

          The Master Servicer, with respect to a Mortgaged Property that secures
a Performing Serviced Mortgage Loan, and the Special Servicer, with respect to a
Mortgaged Property that secures a Specially Serviced Mortgage Loan or with
respect to an Administered REO Property, shall prepare and maintain one CMSA
Operating Statement Analysis Report for each such Mortgaged Property and
Administered REO Property. The CMSA Operating Statement Analysis Report for each
such Mortgaged Property and REO Property is to be updated by the Master Servicer
or Special Servicer, as applicable, within 30 days after its receipt of updated
operating statements for a Mortgaged Property or REO Property, as the case may
be. The Master Servicer or Special Servicer, as applicable, shall use the


                                     -210-



"Normalized" column from the CMSA NOI Adjustment Worksheet for any Mortgaged
Property or REO Property, as the case may be, to update and normalize the
corresponding annual year-end information in the CMSA Operating Statement
Analysis Report and shall use any annual operating statements and related data
fields received with respect to any Mortgaged Property or REO Property, as the
case may be, to prepare the CMSA NOI Adjustment Worksheet for such property.
Copies of CMSA Operating Statement Analysis Reports and CMSA NOI Adjustment
Worksheets (as well as any comparable items received with respect to an Outside
Serviced Trust Mortgage Loan or any related REO Property) are to be forwarded by
the Master Servicer or the Special Servicer, as applicable, to each other, the
Trustee and any Controlling Class Certificateholder, in each case upon request.

          (b) Not later than 12:00 p.m. (New York City time) on the Business Day
after each Trust Determination Date, the Special Servicer shall deliver or cause
to be delivered to the Master Servicer the following reports with respect to the
Specially Serviced Trust Mortgage Loans and any Administered REO Properties and,
to the extent that the subject information relates to when they were Specially
Serviced Trust Mortgage Loans, with respect to any Corrected Trust Mortgage
Loans, providing the required information as of the related Determination Date:
(A) a CMSA Property File; (B) a CMSA Comparative Financial Status Report; (C) a
CMSA Delinquent Loan Status Report; (D) a Loan Payoff Notification Report; (E) a
CMSA Historical Liquidation Report; (F) a CMSA Historical Loan Modification and
Corrected Mortgage Loan Report; and (G) a CMSA REO Status Report.

          (c) Not later than 2:00 p.m. (New York City time) on the second
Business Day prior to each Distribution Date, the Master Servicer shall furnish
to the Trustee and, upon request, to the Depositor, the Underwriters and the
Special Servicer, by electronic transmission (or in such other form to which the
Trustee or the Depositor, as the case may be, and the Master Servicer may
agree), an accurate and complete CMSA Loan Periodic Update File providing the
required information for the Trust Mortgage Loans and any REO Trust Mortgage
Loans as of the related Determination Date (or, in the case of an Outside
Serviced Trust Mortgage Loan or any successor REO Trust Mortgage Loan with
respect thereto, as of the end of the related Underlying Collection Period). In
the case of information to be furnished by the Master Servicer to the Trustee
pursuant to this Section 3.12(c), insofar as such information is solely within
the control of the Special Servicer, the Master Servicer (if other than the
Special Servicer or an Affiliate thereof) shall have no obligation to provide
such information until it has received such information from the Special
Servicer, shall not be in default hereunder due to a delay in providing the CMSA
Loan Periodic Update File caused by the Special Servicer's failure to timely
provide any report required under this Agreement and may, absent actual
knowledge of an error therein, conclusively rely on the reports to be provided
by the Special Servicer. The Master Servicer may conclusively rely on any
information provided by the respective Mortgage Loan Sellers or any Mortgagor
with respect to the CMSA Loan Periodic Update File, CMSA Loan Setup File, CMSA
Property File and CMSA Financial File.

          Not later than 4:00 p.m. (New York City time) on the first Business
Day prior to each Distribution Date, the Master Servicer shall deliver or cause
to be delivered to the Trustee, the Rating Agencies, the Special Servicer and,
upon request, any Controlling Class Certificateholder: (i) the most recent CMSA
Historical Loan Modification and Corrected Mortgage Loan Report, CMSA Historical
Liquidation Report and CMSA REO Status Report received from the Special Servicer
pursuant to Section 3.12(b); (ii) the most recent CMSA Property File, CMSA
Financial File, CMSA Loan Setup File (if modified), CMSA Loan Level Reserve/LOC
Report, CMSA Delinquent Loan Status Report, CMSA Comparative Financial Status
Report and Loan Payoff Notification Report (in each case combining the


                                     -211-



reports prepared by the Special Servicer and the Master Servicer); (iii) a CMSA
Servicer Watch List with information that is current as of the related
Determination Date with respect to each subject Trust Mortgage Loan; and (iv) a
CMSA Advance Recovery Report providing the required information for the Trust
Mortgage Loans and any REO Trust Mortgage Loans as of the related Determination
Date (or, in the case of an Outside Serviced Trust Mortgage Loan or any
successor REO Trust Mortgage Loan with respect thereto, as of the end of the
related Underlying Collection Period).

          The Master Servicer shall incorporate in the foregoing reports
referred to above in this Section 3.12(c) any information and reports received
(by the date in the month of such Distribution Date that such information and
reports are scheduled to be received in accordance with the related Outside
Servicing Agreement) from the applicable Outside Servicer with respect to each
Outside Serviced Trust Mortgage Loan or any successor REO Trust Mortgage Loan
with respect thereto. The Master Servicer shall include on one of such reports
updated information as of the applicable Determination Date regarding the amount
of accrued and unpaid interest on Advances in accordance with Section 3.11(g)
and/or 4.03(d), such information to be presented on a loan-by-loan basis.

          (d) If the Master Servicer or the Special Servicer determines, in its
reasonable judgment, that information regarding the Trust Mortgage Loans and REO
Properties (in addition to the information otherwise required to be contained in
the CMSA Investor Reporting Package) should be disclosed to Certificateholders
and Certificate Owners, then the Master Servicer or, solely as to Specially
Serviced Mortgage Loans and Administered REO Properties, the Special Servicer,
shall so notify the Trustee, set forth such information in an additional report,
in a format reasonably acceptable to the Trustee and the Master Servicer and, if
applicable, the Special Servicer (the "Supplemental Report"), and deliver such
report to the Trustee upon preparation thereof or simultaneously with the
delivery of the Master Servicer's reports described in Section 3.12(c).

          (e) The Special Servicer shall deliver to the Master Servicer the
reports set forth in Section 3.12(b) in an electronic format reasonably
acceptable to the Special Servicer and the Master Servicer, and the Master
Servicer shall deliver to the Trustee, the Special Servicer and, upon request,
any Controlling Class Certificateholder the reports set forth in Section 3.12(c)
in an electronic format reasonably acceptable to the Master Servicer and the
Trustee. The Master Servicer may, absent manifest error, conclusively rely on
the reports to be provided by the Special Servicer pursuant to Section 3.12(b)
and, with respect to an Outside Serviced Trust Mortgage Loan or an Outside
Administered REO Property, by a related Outside Servicer pursuant to the related
Outside Servicing Agreement. The Trustee may, absent manifest error,
conclusively rely on the reports to be provided by the Master Servicer pursuant
to Section 3.12(c) to the extent that the underlying information is solely
within the control of the Master Servicer or the Special Servicer, and the
Trustee shall not be responsible to recompute, recalculate or verify the
information provided to it by the Master Servicer. In the case of information or
reports to be furnished by the Master Servicer to the Trustee pursuant to
Section 3.12(c), if and to the extent that such information is based on reports
to be provided by the Special Servicer pursuant to Section 3.12(b) or by an
Outside Servicer pursuant to an Outside Servicing Agreement, or if and to the
extent such reports are to be prepared and delivered by the Special Servicer
pursuant to Section 3.12(b) or by an Outside Servicer pursuant to an Outside
Servicing Agreement, then, so long as the Master Servicer and the party required
to provide the subject reports are not the same Person or Affiliates, the Master
Servicer shall have no obligation to provide such information or reports to the
Trustee until it has received such information or reports from the Special
Servicer or the relevant Outside Servicer, as applicable, and the Master
Servicer is entitled to conclusively rely on such


                                     -212-



information provided by the Special Servicer or relevant Outside Servicer, as
applicable. The Master Servicer shall not be in default hereunder due to a delay
in providing the reports required by Section 3.12(c) caused by the Special
Servicer's failure to timely provide any report required under Section 3.12(b)
of this Agreement, or by an Outside Servicer's failure to provide any report
required to be provided to the holder of the related Outside Serviced Trust
Mortgage Loan pursuant to the related Outside Servicing Agreement or the related
Co-Lender Agreement, as applicable.

          (f) The preparation and maintenance by the Master Servicer and the
Special Servicer of all the reports specified in this Section 3.12, including
the calculations made therein, shall be done in accordance with CMSA standards
to the extent applicable thereto.

          SECTION 3.12A. Preparation and Delivery of Certain Statements and
                         Reports to the Serviced Non-Trust Mortgage Loan
                         Noteholders.

          (a) The Master Servicer shall promptly deliver to each Serviced
Non-Trust Mortgage Loan Noteholder: (i) copies of operating statements and rent
rolls; (ii) upon request, annual CMSA NOI Adjustment Worksheets (with annual
operating statements as exhibits); and (iii) annual CMSA Operating Statement
Analysis Reports, in each case prepared, received or obtained by it pursuant to
Section 3.12 with respect to the Mortgaged Property securing the related
Serviced Loan Combination.

          (b) If the Mortgage Loans forming a Serviced Loan Combination
constitute Specially Serviced Mortgage Loans, or if a Mortgaged Property
securing a Serviced Loan Combination has become an REO Property, then each
calendar month, not later than 12:00 p.m. (New York City time) on the Business
Day after the applicable Loan Combination Determination Date in such month, the
Special Servicer shall deliver or cause to be delivered to the Master Servicer
the following reports with respect to such Serviced Loan Combination and/or the
related Mortgaged Property, providing the required information as of such Loan
Combination Determination Date: (i) a CMSA Property File (or similar report
satisfactory to the Master Servicer); and (ii) a CMSA Comparative Financial
Status Report (or similar report satisfactory to the Master Servicer). If the
Mortgage Loans forming a Serviced Loan Combination constitute Specially Serviced
Mortgage Loans, or if a Mortgaged Property securing a Serviced Loan Combination
has become an REO Property, then each calendar month, not later than 10:00 a.m.
(New York City time) on the second Business Day prior to the applicable Loan
Combination Master Servicer Remittance Date in such month, the Special Servicer
shall deliver or cause to be delivered to the Master Servicer such of the

Combination and/or the related Mortgaged Property: (i) a CMSA Delinquent Loan
Status Report; (ii) a Loan Payoff Notification Report, (iii) a CMSA Historical
Liquidation Report; (iv) a CMSA Historical Loan Modification and Corrected
Mortgage Loan Report; and (v) a CMSA REO Status Report.

          (c) Prior to 4:00 p.m. (or, in the case of a Serviced Non-Trust Loan
that is part of a Non-Trust Mortgage Loan Securitization Trust, 2:00 p.m.) (New
York City time) on each applicable Master Servicer Remittance Date, the Master
Servicer shall, with respect to each Serviced Loan Combination, prepare all Loan
Combination Servicing Reports as may be relevant and that are not otherwise
required to be prepared by the Special Servicer pursuant to Section 3.12A(b).
The Master Servicer shall also include on one of such reports updated
information as of the applicable Loan Combination Determination Date regarding
the amount of accrued and unpaid interest on Advances in


                                     -213-



accordance with Section 3.11(g) and/or 4.03(d), such information to be presented
on a loan-by-loan basis.

          (d) The Special Servicer shall deliver to the Master Servicer the
reports set forth in Section 3.12A(b) in an electronic format reasonably
acceptable to the Special Servicer and the Master Servicer. The Master Servicer
may, absent manifest error, conclusively rely on the reports to be provided by
the Special Servicer pursuant to Section 3.12A(b). In the case of information or
reports to be furnished by the Master Servicer to a Serviced Non-Trust Mortgage
Loan Noteholder pursuant to Section 3.12A(f), to the extent that such
information is based on reports to be provided by the Special Servicer pursuant
to Section 3.12A(b) and/or that such reports are to be prepared and delivered by
the Special Servicer pursuant to Section 3.12A(b), so long as the Master
Servicer and the Special Servicer are not the same Person or Affiliates, the
Master Servicer shall have no obligation to provide such information or reports
until it has received such information or reports from the Special Servicer, and
the Master Servicer shall not be in default hereunder due to a delay in
providing the reports required by Section 3.12A(f) caused by the Special
Servicer's failure to timely provide any report required under Section 3.12A(b)
of this Agreement.

          (e) The preparation and maintenance by the Master Servicer and the
Special Servicer of all the reports specified in this Section 3.12A, including
the calculations made therein, shall be done in accordance with CMSA standards,
to the extent applicable thereto.

          (f) Not later than 4:00 p.m. (or, in the case of a Serviced Non-Trust
Loan that is part of a Non-Trust Mortgage Loan Securitization Trust, 2:00 p.m.)
(New York City time) on each related Master Servicer Remittance Date, the Master
Servicer shall forward to the related Non-Trust Mortgage Loan Noteholder(s) all
related Loan Combination Servicing Reports prepared with respect to each
Serviced Loan Combination, pursuant to this Section 3.12A, during the calendar
month in which such Master Servicer Remittance Date occurs.

          (g) The Master Servicer shall only be obligated to deliver the
statements, reports and information contemplated by Section 3.12A(f) to the
extent it receives the necessary underlying information from the Special
Servicer and shall not be liable for its failure to deliver such statements,
reports and information on the prescribed due dates, to the extent caused by the
failure of the Special Servicer to deliver timely such underlying information.
Nothing herein shall obligate the Master Servicer or the Special Servicer to
violate any applicable law prohibiting disclosure of information with respect to
the related Mortgagor, and the failure of the Master Servicer or the Special
Servicer to disseminate information for such reason shall not be a breach
hereunder.

          Absent manifest error of which it has actual knowledge, neither the
Master Servicer nor the Special Servicer shall be responsible for the accuracy
or completeness of any information supplied to it by a Mortgagor, a Mortgage
Loan Seller or third party that is included in any reports, statements,
materials or information prepared or provided by the Master Servicer or the
Special Servicer, as applicable, pursuant to this Agreement. Neither the Master
Servicer nor the Special Servicer shall have any obligation to verify the
accuracy or completeness of any information provided by a Mortgagor, a Mortgage
Loan Seller, a third party or each other.

          SECTION 3.13.  Annual Statement as to Compliance.

          Each of the Trustee, the Master Servicer and the Special Servicer
shall deliver (or, in the case of the Trustee, make available), and shall cause
(or, in the case of the Master Servicer with respect to a Sub-Servicer
identified on Exhibit K hereto, shall use reasonable efforts to cause) each
Additional Item 1123 Servicer retained or engaged by it to deliver, to the
Trustee, the Rating Agencies, the Depositor, the Underwriters, each Serviced
Non-Trust Mortgage Loan Noteholder and each other, at no expense to the Trust,
on or before April 30 of each year, beginning in 2007 (or, as to any such year,
such earlier date as is contemplated by the last sentence of this Section 3.13),
a statement of compliance (the "Annual Statement of Compliance") from the
Trustee, the Master Servicer, the Special Servicer or such Additional Item 1123
Servicer, as the case may be, signed by an authorized officer thereof, to the
effect that (i) a review of the activities of the Trustee, the Master Servicer,
the Special Servicer or such Additional Item 1123 Servicer, as the case may be,
during the preceding calendar year (or, in the case of the first such
certification, during the period from the Closing Date to December 31, 2006,
inclusive) and, in particular, of its performance under this Agreement (or, in
the case of an Additional Item 1123 Servicer, under the applicable Sub-Servicing
Agreement or primary servicing agreement), has been made under such officer's
supervision, and (ii) to the best of such officer's knowledge, based on such
review, the Trustee, the Master Servicer, the Special Servicer or such
Additional Item 1123 Servicer, as the case may be, has fulfilled all of its
obligations under this Agreement (or, in the case of an Additional Item 1123
Servicer, under the applicable Sub-Servicing Agreement or primary servicing
agreement) in all material respects throughout such preceding calendar year or
portion thereof (or, if there has been a failure to fulfill any such obligation
in any material respect, specifying each such failure known to such officer and
the nature and status thereof). Notwithstanding the timing provided for in the
first sentence of this paragraph, if (as confirmed in writing by the Depositor)
the Depositor or any other party hereto is required to file an Annual Report on
Form 10-K with the Commission in respect of the Trust covering any particular
calendar year, or (if applicable) any other depositor, trustee and/or other
certifying party and certifying officer with respect to a related securitization
trust is required to file an Annual Report on Form 10-K with the Commission in
connection with the securitization of any Serviced Non-Trust Mortgage Loan
covering any particular calendar year and so notifies the Trustee, the Master
Servicer and the Special Servicer, then the Annual Statement of Compliance to be
delivered during the following year by each of the Trustee, the Master Servicer
and the Special Servicer, and by each Additional Item 1123 Servicer with which
the Master Servicer or Special Servicer has entered into a servicing
relationship with respect to any one or more Mortgage Loans, shall be delivered

Serviced Non-Trust Mortgage Loan Noteholder and any such depositor, trustee
and/or other certifying party and certifying officer with respect to a related
securitization trust, as applicable; and the Master Servicer and the Special
Servicer are hereby notified that the Depositor is required to file an Annual
Report on Form 10-K with the Commission in respect of the Trust covering
calendar year 2006.

          In the event that the Master Servicer, the Special Servicer or the
Trustee is terminated or resigns pursuant to the terms of this Agreement, such
party shall provide, and shall cause (or, in the case of the Master Servicer
with respect to a Sub-Servicer identified on Exhibit K hereto, shall use
reasonable efforts to cause) any Additional Item 1123 Servicer retained or
engaged by such party to provide, an annual statement of compliance pursuant to
this Section 3.13 with respect to the period of time that the Master Servicer,
the Special Servicer or the Trustee was subject to this Agreement. In addition,
in the event that any Additional Item 1123 Servicer retained or engaged by the
Master Servicer, the Special


                                     -215-



Servicer or the Trustee is terminated or resigns pursuant to the terms of any
applicable servicing agreement, such party shall cause (or, in the case of the
Master Servicer with respect to a Sub-Servicer identified on Exhibit K hereto,
shall use reasonable efforts to cause) the subject Additional Item 1123 Servicer
retained or engaged by such party to provide an annual statement of compliance
pursuant to this Section 3.13 with respect to the period of time that the
Additional Item 1123 Servicer was subject to such other servicing agreement.

          In the event the Trustee or the Depositor does not receive the Annual
Statement of Compliance with respect to any party hereto or, if the Trustee has
been notified of the existence thereof, any Additional Item 1123 Servicer
contemplated to deliver such report pursuant to the preceding paragraph, by
March 15th of any year during which an Annual Report on Form 10-K is required to
be filed with the Commission with respect to the Trust, then the Trustee shall,

of an Additional Item 1123 Servicer known to the Trustee or the Depositor, as
the case may be, to the party hereto that retained or engaged such Additional
Item 1123 Servicer), with a copy of such Servicer Notice to the Depositor (if
the Trustee is sending the Servicer Notice) or the Trustee (if the Depositor is
sending the Servicer Notice), as applicable, within two (2) Business Days of
such failure. Any party hereto that retains or engages, during an Exchange Act
Reporting Year, a Servicing Representative (other than a Sub-Servicer identified
on Exhibit K hereto) that is, with respect to such Exchange Act Reporting Year,
an Additional Item 1123 Servicer shall so notify the Trustee (unless such party
is the Trustee) and the Depositor in writing promptly following such party's
becoming aware that such Servicing Representative is or has become an Additional
Item 1123 Servicer; and, further, if such Servicing Representative does not
deliver an Annual Statement of Compliance with respect to itself by March 15th
of any year during which a Form 10-K is required to be filed with the Commission
with respect to the Trust, the party hereto that retained or engaged such
Servicing Representative shall so notify the Trustee (unless such party is the
Trustee) and the Depositor in writing no later than the second Business Day
following such March 15th.

                         Criteria; Registered Public Accounting Firm Attestation

the case of the Master Servicer with respect to a Sub-Servicer identified on
Exhibit K hereto, shall use reasonable efforts to cause) any Sub-Servicing

of each year, beginning in 2007 (or, as to any such year, such earlier date as
is contemplated by the last sentence of this paragraph), to the Trustee, to the
Depositor, to each Serviced Non-Trust Mortgage Loan Noteholder and, in the case
of a Servicing Function Participant (other than the Master Servicer and the
Trustee) or a Sub-Servicing Function Participant, to the Master Servicer, at no
expense to the Trust, the following reports: (i) as required under Rules 13a-18

public accounting firm has issued an attestation report on such Servicing
Function Participant's or such Sub-Servicing Function Participant's, as the case

further agreed that, if any such Servicing Function Participant's or such
Sub-Servicing Function Participant's, as the case may be, Annual Assessment
Report or Annual Attestation Report (as defined below) identifies any material
instance of noncompliance with the Relevant Servicing Criteria, such Servicing
Function Participant or the party hereto that retained such Sub-Servicing
Function Participant, as the case may be, shall contemporaneously deliver to the
indicated recipients above a separate statement identifying such material
instance of noncompliance, and if any such Servicing Function Participant's or
such Sub-Servicing Function Participant's Annual Assessment Report or Annual

(1) Business Day following the date on which such report was to be delivered)
provide to the intended recipients above notice of such failure, together with
an associated explanation as to why such report has not been delivered (in the
case of the Master Servicer with respect to a Sub-Servicer identified on Exhibit
K hereto, to the extent such explanation can be obtained from such Sub-Servicer
with reasonable efforts)); and (ii) as an exhibit to each report delivered by a
Servicing Function Participant or a Sub-Servicing Function Participant pursuant
to the immediately preceding clause (i), as required under Rules 13a-18 or
15d-18 of the Exchange Act and Item 1122 of Regulation AB, an attestation report

consent of such registered public accounting firm authorizing the filing of such
Annual Attestation Report with the Commission as part of any registration

after receipt of each such report delivered pursuant to the second preceding
sentence, the Depositor shall review such report and, if applicable, shall be
entitled to consult with the appropriate party hereto as to the nature of any
material instance of noncompliance with the Relevant Servicing Criteria by such
party or any Sub-Servicing Function Participant that such party has retained or
engaged. Notwithstanding the timing provided for in the first sentence of this
paragraph, if (as confirmed in writing by the Depositor) the Depositor is

the Trust covering any particular calendar year, or (if applicable) any other
depositor, trustee and/or other certifying party and certifying officer with

Trustee is terminated or resigns pursuant to the terms of this Agreement, such
party shall provide, and shall cause (or, in the case of the Master Servicer

          In the event the Trustee or the Depositor does not receive the Annual
Assessment Report and/or the Annual Attestation Report with respect to any
Servicing Function Participant, or with respect to any Sub-Servicing Function
Participant retained or engaged by a party hereto that is known to the Trustee
or the Depositor, as the case may be, by March 15th of any year during which an
Annual Report on Form 10-K is required to be filed with the Commission with

Servicer to no more than three e-mail addresses in the aggregate in order to
fulfill its notification requirement as set forth in the preceding sentence
and/or under the provisions of Section 7.01(v)(B).

          Any party hereto that retains or engages, during an Exchange Act
Reporting Year, a Servicing Representative (other than a Sub-Servicer identified

Exchange Act, provided that the Master Servicer, the Special Servicer, the
Trustee and any Fiscal Agent shall each be entitled to charge the Depositor for
any reasonable additional costs and expenses incurred by it in affording the
Depositor such cooperation.

as such to the reasonable satisfaction of the Master Servicer or the Special
Servicer, as the case may be) or any Serviced Non-Trust Mortgage Loan

of any Serviced Non-Trust Mortgage Loan Noteholder or any regulatory authority
seeking such access in respect of a Serviced Non-Trust Mortgage Loan Noteholder,
to records relating to the related Serviced Non-Trust Mortgage Loan), except to
the extent it is prohibited from doing so by applicable law or contract or to
the extent such information is subject to a privilege under applicable law to be

Loan Noteholders. Such access shall be afforded only upon reasonable prior
written request and during normal business hours at the offices of the Master
Servicer or the Special Servicer, as the case may be, designated by it.

          In connection with providing or granting any information or access
pursuant to the prior paragraph to a Certificateholder, a Certificate Owner, a
Serviced Non-Trust Mortgage Loan Noteholder or any regulatory authority that may
exercise authority over a Certificateholder, a Certificate Owner or a Serviced
Non-Trust Mortgage Loan Noteholder, the Master Servicer and the Special Servicer
each may require payment from such Certificateholder, a Certificate Owner or a
Serviced Non-Trust Mortgage Loan Noteholder of a sum sufficient to cover the
reasonable costs and expenses of providing such


                                     -219-



information or access, including copy charges and reasonable fees for employee
time and for space; provided that no charge may be made if such information or
access was required to be given or made available under applicable law. In
connection with providing Certificateholders and Certificate Owners access to
the information described in the preceding paragraph, the Master Servicer and
the Special Servicer shall require (prior to affording such access) a written
confirmation executed by the requesting Person substantially in such form as may
be reasonably acceptable to the Master Servicer or the Special Servicer, as the
case may be, generally to the effect that such Person is a Holder of
Certificates or a beneficial holder of Book-Entry Certificates and will keep
such information confidential.

          Upon the reasonable request of any Certificateholder, or any
Certificate Owner identified to the Master Servicer to the Master Servicer's
reasonable satisfaction, the Master Servicer may provide (or forward
electronically) (at the expense of such Certificateholder or Certificate Owner)
copies of any operating statements, rent rolls and financial statements obtained
by the Master Servicer or the Special Servicer; provided that, in connection
therewith, the Master Servicer shall require a written confirmation executed by
the requesting Person substantially in such form as may be reasonably acceptable
to the Master Servicer, generally to the effect that such Person is a Holder of
Certificates or a beneficial holder of Book-Entry Certificates and will keep
such information confidential.

          (b) No less often than on a monthly basis, upon reasonable prior
notice and during normal business hours, each of the Master Servicer and the
Special Servicer shall, without charge, make a knowledgeable Servicing Officer
available to answer questions (if and to the extent the Master Servicer or the
Special Servicer, as the case may be, is responsible (or, in the case of the
Special Servicer, would be responsible upon the occurrence of a Servicing
Transfer Event) for the servicing thereof) from the following parties: (i) the
Controlling Class Representative regarding the performance and servicing of the
Mortgage Loans and/or the REO Properties; and (ii) the related Serviced Loan
Combination Controlling Party regarding the performance and servicing of each
Serviced Loan Combination and/or any related REO Property. Except as provided in
the following sentence, in connection with providing the Controlling Class
Representative with the information described in the preceding sentence, the
Master Servicer and the Special Servicer shall require (prior to providing such
information for the first time to such Controlling Class Representative) a
Controlling Class Representative Confirmation (as defined in Section 6.09(b)),
generally to the effect that such Person will keep any information received by
it from time to time pursuant to this Agreement confidential (other than with
respect to communications with the Controlling Class). In the case of the
initial Controlling Class Representative, upon its or an Affiliate's acquisition
of the Class T Certificates, such entity shall be deemed to have agreed to keep
all non-public information received by it in such capacity from time to time
pursuant to this Agreement confidential, subject to applicable law, and such
initial Controlling Class Representative shall be deemed to have made such
agreement without delivery of the Controlling Class Representative Confirmation.

          SECTION 3.16.  Title to REO Property; REO Accounts.

          (a) If title to any Mortgaged Property (other than a Mortgaged
Property that secures an Outside Serviced Loan Combination) is acquired, the
deed or certificate of sale shall be issued to the Trustee or its nominee on
behalf of the Certificateholders and, in the case of a Mortgaged Property that
secures a Serviced Loan Combination, on behalf of the related Serviced Non-Trust
Mortgage Loan Noteholder(s). If, pursuant to Section 3.09(b), the Special
Servicer formed or caused to be formed, at the expense of the Trust, a single
member limited liability company (of which the Trust is the sole


                                     -220-



member) for the purpose of taking title to one or more Administered REO
Properties pursuant to this Agreement, then (subject to the interests of any
affected Serviced Non-Trust Mortgage Loan Noteholder), the deed or certificate
of sale with respect to any such Administered REO Property shall be issued to
such single member limited liability company. The limited liability company
shall be a manager-managed limited liability company, with the Special Servicer
to serve as the initial manager to manage the property of the limited liability
company, including any applicable Administered REO Property, in accordance with
the terms of this Agreement as if such property was held directly in the name of
the Trust or Trustee under this Agreement.

          The Special Servicer, on behalf of the Trust Fund and, in the case of
any Administered REO Property that relates to a Serviced Loan Combination, the
related Serviced Non-Trust Mortgage Loan Noteholder(s), shall sell any
Administered REO Property by the end of the third calendar year following the
calendar year in which the applicable REMIC Pool acquires ownership of such REO
Property for purposes of Section 860G(a)(8) of the Code, unless the Special
Servicer either (i) applies, more than 60 days prior to the end of such third
succeeding year, for and is granted an extension of time (an "REO Extension") by
the IRS to sell such REO Property or (ii) obtains for the Trustee an Opinion of
Counsel, addressed to the Trustee, the Special Servicer and the Master Servicer,
to the effect that the holding by the applicable REMIC Pool of such Administered
REO Property subsequent to the end of such third succeeding year will not result
in the imposition of taxes on "prohibited transactions" (as defined in Section
860F of the Code) of any REMIC Pool or cause any REMIC Pool to fail to qualify
as a REMIC at any time that any Certificates are outstanding. If the Special
Servicer is granted the REO Extension contemplated by clause (i) of the
immediately preceding sentence or obtains the Opinion of Counsel contemplated by
clause (ii) of the immediately preceding sentence, the Special Servicer shall
sell the subject Administered REO Property within such extended period as is
permitted by such REO Extension or such Opinion of Counsel, as the case may be.
Any expense incurred by the Special Servicer in connection with its obtaining
the REO Extension contemplated by clause (i) of the second preceding sentence or
its obtaining the Opinion of Counsel contemplated by clause (ii) of the second
preceding sentence, or for the creation of and the operating of a single member
limited liability company, shall be covered by, and reimbursable as, a Servicing
Advance.

          (b) The Special Servicer shall segregate and hold all funds collected
and received in connection with any Administered REO Property separate and apart
from its own funds and general assets. If an REO Acquisition shall occur in
respect of any Mortgaged Property (other than a Mortgaged Property that secures
a Loan Combination), the Special Servicer shall establish and maintain one or
more accounts (collectively, the "Pool REO Account"), to be held on behalf of
the Trustee in trust for the sole benefit of the Certificateholders, for the
retention of revenues and other proceeds derived from each REO Property (other
than any REO Property that relates to a Loan Combination). If such REO
Acquisition occurs with respect to the Mortgaged Property that secures any
Serviced Loan Combination, then the Special Servicer shall establish one or more
accounts solely with respect to such property (the related "Loan Combination REO
Account"), to be held for the sole benefit of the Certificateholders and the
related Serviced Non-Trust Mortgage Loan Noteholder(s). The Pool REO Account and
each Loan Combination REO Account shall each be an Eligible Account. The Special
Servicer shall deposit, or cause to be deposited, in the applicable REO Account,
upon receipt, all REO Revenues, Insurance Proceeds, Condemnation Proceeds and
Liquidation Proceeds received in respect of any Administered REO Property. Funds
in an REO Account (other than any such funds representing Additional Interest)
may be invested in Permitted Investments in accordance with Section 3.06. The
Special Servicer shall be entitled to make withdrawals from an REO Account to
pay itself, as additional special servicing


                                     -221-



compensation in accordance with Section 3.11(d), interest and investment income
earned in respect of amounts held in such REO Account as provided in Section
3.06(b) (but only to the extent of the Net Investment Earnings with respect to
such REO Account for any related Investment Period). The Special Servicer shall
give notice to the Trustee and the Master Servicer of the location of each REO
Account, and shall give notice to the related Serviced Non-Trust Mortgage Loan
Noteholder(s) of the location of any Loan Combination REO Account, in each case
when first established and of the new location of any such REO Account prior to
any change thereof.

          (c) The Special Servicer shall withdraw from the related REO Account
funds necessary for the proper operation, management, leasing, maintenance and
disposition of any Administered REO Property, but only to the extent of amounts
on deposit in such REO Account relating to such REO Property. On the Business
Day following each Trust Determination Date, the Special Servicer shall withdraw
from any Pool REO Account and deposit into the Pool Custodial Account (or
deliver to the Master Servicer or such other Person as may be designated by the
Master Servicer for deposit into the Pool Custodial Account) the aggregate of
all amounts received in respect of each Administered REO Property (other than
any Administered REO Property relating to a Serviced Loan Combination) during
the Trust Collection Period ending on such Trust Determination Date, net of any
withdrawals made out of such amounts pursuant to the preceding sentence and,
further, net of any reserves to be maintained in the Pool REO Account in
accordance with the last sentence of this Section 3.16(c). On the Business Day
following each related Loan Combination Determination Date, the Special Servicer
shall withdraw from the Loan Combination REO Account related to any Serviced
Loan Combination and deposit into the Loan Combination Custodial Account that
relates to such Serviced Loan Combination (or deliver to the Master Servicer or
such other Person as may be designated by the Master Servicer for deposit into
such Loan Combination Custodial Account) the aggregate of all amounts received
in respect of any Administered REO Property that relates to such Serviced Loan
Combination during the related Loan Combination Collection Period ending on such
related Loan Combination Determination Date, net of any withdrawals made out of
such amounts pursuant to the second preceding sentence and, further, net of any
reserves to be maintained in the related Loan Combination REO Account in
accordance with the last sentence of this Section 3.16(c). Notwithstanding the
foregoing, the Special Servicer may retain in the related REO Account such
portion of proceeds and collections in respect of any Administered REO Property
as may be necessary to maintain a reserve of sufficient funds for the proper
operation, management, leasing, maintenance and disposition of such REO Property
(including the creation of a reasonable reserve for repairs, replacements,
necessary capital replacements and other related expenses), such reserve not to
exceed an amount sufficient to cover such items to be incurred during the
following twelve-month period.

          (d) The Special Servicer shall keep and maintain separate records, on
a property-by-property basis, for the purpose of accounting for all deposits to,
and withdrawals from, each REO Account pursuant to Section 3.16(b) or (c). The
Special Servicer shall provide the Master Servicer any information with respect
to each REO Account as is reasonably requested by the Master Servicer.

          (e) Notwithstanding anything to the contrary, this Section 3.16 shall
not apply to any Outside Administered REO Property.


                                     -222-



          SECTION 3.17.  Management of REO Property.

          (a) Prior to the acquisition by it of title to a Mortgaged Property
(other than a Mortgaged Property that secures an Outside Serviced Loan
Combination), the Special Servicer shall review the operation of such Mortgaged
Property and determine the nature of the income that would be derived from such
property if it were acquired by the Trust Fund. If the Special Servicer
determines from such review that:

               (i) None of the income from Directly Operating such Mortgaged
     Property would be subject to tax as "net income from foreclosure property"
     within the meaning of the REMIC Provisions or would be subject to the tax
     imposed on "prohibited transactions" under Section 860F of the Code (either
     such tax referred to herein as an "REO Tax"), then such Mortgaged Property
     may be Directly Operated by the Special Servicer as REO Property;

               (ii) Directly Operating such Mortgaged Property as REO Property
     could result in income from such property that would be subject to an REO
     Tax, but that a lease of such property to another party to operate such
     property, or the performance of some services by an Independent Contractor
     with respect to such property, or another method of operating such property
     would not result in income subject to an REO Tax, then the Special Servicer
     may (provided that in the good faith and reasonable judgment of the Special
     Servicer, it is commercially reasonable) acquire such Mortgaged Property as
     REO Property and so lease or operate such REO Property; or

               (iii) It is reasonable to believe that Directly Operating such
     property as REO Property could result in income subject to an REO Tax and
     that no commercially reasonable means exists to operate such property as
     REO Property without the Trust Fund incurring or possibly incurring an REO
     Tax on income from such property, the Special Servicer shall deliver to the
     Tax Administrator, in writing, a proposed plan (the "Proposed Plan") to
     manage such property as REO Property. Such plan shall include potential
     sources of income, and, to the extent reasonably possible, estimates of the
     amount of income from each such source. Upon request of the Special
     Servicer, the Tax Administrator shall advise the Special Servicer of the
     Tax Administrator's federal income tax reporting position with respect to
     the various sources of income that the Trust Fund would derive under the
     Proposed Plan. After receiving the information described in the preceding
     sentence from the Tax Administrator, the Special Servicer shall implement
     the Proposed Plan (after acquiring the respective Mortgaged Property as REO
     Property), with any amendments required to be made thereto as a result of
     the Tax Administrator's tax reporting position.

          The Special Servicer's decision as to how each Administered REO
Property shall be managed and operated shall be based on the Servicing Standard
and, further, based on the good faith and reasonable judgment of the Special
Servicer as to which means would be in the best interest of the
Certificateholders (and, in the case of any Administered REO Property related to
a Serviced Loan Combination, the related Serviced Non-Trust Mortgage Loan
Noteholder(s)), as a collective whole, by maximizing (to the extent commercially
reasonable and consistent with Section 3.17(b)) the net after-tax REO Revenues
received with respect to such property without materially impairing the Special
Servicer's ability to promptly sell such property for a fair price. In
connection with performing their respective duties under this Section 3.17(a),
both the Special Servicer and the Tax Administrator may


                                     -223-



consult with counsel and tax accountants, the reasonable cost of which
consultation shall be covered by, and be reimbursable as, a Servicing Advance to
be made by the Special Servicer.

          (b) If title to any Administered REO Property is acquired, the Special
Servicer shall manage, conserve, protect and operate such REO Property for the
benefit of the Certificateholders (and, in the case of any Administered REO
Property related to a Serviced Loan Combination, the related Serviced Non-Trust
Mortgage Loan Noteholder(s)) solely for the purpose of its prompt disposition
and sale in a manner that does not and will not: (i) cause such REO Property to
fail to qualify as "foreclosure property" within the meaning of Section
860G(a)(8) of the Code for purposes of Section 860D(a) of the Code; or (ii)
except as contemplated by Section 3.17(a), either result in the receipt by any
REMIC Pool of any "income from non-permitted assets" within the meaning of
Section 860F(a)(2)(B) of the Code or result in an Adverse REMIC Event or an
Adverse Grantor Trust Event. Subject to the foregoing, however, the Special
Servicer shall have full power and authority to do any and all things in
connection therewith as are consistent with the Servicing Standard and,
consistent therewith, shall withdraw from the related REO Account, to the extent
of amounts on deposit therein with respect to any Administered REO Property,
funds necessary for the proper operation, management, maintenance and
disposition of such REO Property, including:

               (i) all insurance premiums due and payable in respect of such REO
     Property;

               (ii) all real estate taxes and assessments in respect of such REO
     Property that may result in the imposition of a lien thereon;

               (iii) any ground rents in respect of such REO Property; and

               (iv) all costs and expenses necessary to maintain, lease, sell,
     protect, manage, operate and restore such REO Property.

          To the extent that amounts on deposit in the related REO Account in
respect of any Administered REO Property are insufficient for the purposes set
forth in the preceding sentence with respect to such REO Property, the Master
Servicer shall, at the direction of the Special Servicer, make Servicing
Advances in such amounts as are necessary for such purposes unless the Master
Servicer determines, in accordance with the Servicing Standard, that such
payment would be a Nonrecoverable Advance; provided, however, that the Master
Servicer may make any such Servicing Advance without regard to recoverability if
it is a necessary fee or expense incurred in connection with the defense or
prosecution of legal proceedings.

          (c) Without limiting the generality of the foregoing, the Special
Servicer shall not, with respect to any Administered REO Property:

               (i) enter into, renew or extend any New Lease with respect to
     such Administered REO Property, if the New Lease, by its terms would give
     rise to any income that does not constitute Rents from Real Property;

               (ii) permit any amount to be received or accrued under any New
     Lease other than amounts that will constitute Rents from Real Property;


                                     -224-



               (iii) authorize or permit any construction on such Administered
     REO Property, other than the completion of a building or other improvement
     thereon, and then only if more than 10% of the construction of such
     building or other improvement was completed before default on the related
     Serviced Mortgage Loan became imminent, all within the meaning of Section
     856(e)(4)(B) of the Code; or

               (iv) Directly Operate, or allow any other Person, other than an
     Independent Contractor, to Directly Operate such Administered REO Property
     on any date more than 90 days after the related REO Acquisition;

unless, in any such case, the Special Servicer has obtained an Opinion of
Counsel (the cost of which shall be paid by the Master Servicer, at the
direction of the Special Servicer, and shall be reimbursable as a Servicing
Advance) to the effect that such action would not cause such Administered REO
Property to fail to qualify as "foreclosure property" within the meaning of
Section 860G(a)(8) of the Code for purposes of Section 860D(a) of the Code at
any time that it is held by a REMIC Pool, in which case the Special Servicer may
take such actions as are specified in such Opinion of Counsel.

          (d) The Special Servicer may contract with any Independent Contractor
for the operation and management of any Administered REO Property; provided
that:

               (i) the terms and conditions of any such contract shall not be
     inconsistent herewith and shall reflect an agreement reached at arm's
     length;

               (ii) the fees of such Independent Contractor (which shall be
     expenses of the Trust Fund and, in the case of any Administered REO
     Property that relates to a Serviced Loan Combination, the related Serviced
     Non-Trust Mortgage Loan Noteholder(s)) shall be reasonable and customary in
     consideration of the nature and locality of such Administered REO Property;

               (iii) except as permitted under Section 3.17(a), any such
     contract shall require, or shall be administered to require, that the
     Independent Contractor, in a timely manner, (A) pay out of related REO
     Revenues all costs and expenses incurred in connection with the operation
     and management of such Administered REO Property, including those listed in
     Section 3.17(b) above, and (B) except to the extent that such revenues are
     derived from any services rendered by the Independent Contractor to tenants
     of such Administered REO Property that are not customarily furnished or
     rendered in connection with the rental of real property (within the meaning
     of Section 1.856-4(b)(5) of the Treasury regulations or any successor
     provision), remit all related revenues collected (net of its fees and such
     costs and expenses) to the Special Servicer upon receipt;

               (iv) none of the provisions of this Section 3.17(d) relating to
     any such contract or to actions taken through any such Independent
     Contractor shall be deemed to relieve the Special Servicer of any of its
     duties and obligations hereunder with respect to the operation and
     management of such Administered REO Property; and

               (v) the Special Servicer shall be obligated with respect thereto
     to the same extent as if it alone were performing all duties and
     obligations in connection with the operation and management of such
     Administered REO Property.


                                     -225-



          The Special Servicer shall be entitled to enter into any agreement
with any Independent Contractor performing services for it related to its duties
and obligations under Section 3.16 and this Section 3.17 for indemnification of
the Special Servicer by any such Independent Contractor, and nothing in this
Agreement shall be deemed to limit or modify such indemnification. No agreement
entered into pursuant to this Section 3.17(d) shall be deemed a Sub-Servicing
Agreement for purposes of Section 3.22.

          (e) Notwithstanding anything to the contrary, this Section 3.17 shall
not apply to any Outside Administered REO Property.

          SECTION 3.18.  Sale of Trust Mortgage Loans and Administered REO
                         Properties.

          (a) The Master Servicer, the Special Servicer or the Trustee may sell
or purchase, or permit the sale or purchase of, a Trust Mortgage Loan or
Administered REO Property only in connection with a Permitted Purchase of such
Trust Mortgage Loan or Administered REO Property, as the case may be, and/or in
connection with a sale of such Administered REO Property in accordance with this
Section 3.18.

          (b) Within five (5) Business Days after the Special Servicer has
knowledge that any Trust Mortgage Loan has become a Specially Serviced Trust
Mortgage Loan, the Special Servicer shall give notice of such event to the
related Serviced Non-Trust Mortgage Loan Noteholder(s) (if such Trust Mortgage
Loan is part of a Serviced Loan Combination), each Holder of a Certificate of
the Controlling Class and the Trustee. The Special Servicer, any single
Certificateholder or any group of Certificateholders entitled to a majority of
the Voting Rights allocated to the Controlling Class and any assignees of the
foregoing parties (collectively, the "Purchase Option Holders") shall each have
the option to purchase such Specially Serviced Trust Mortgage Loan at a cash
price that is at least equal to the Purchase Price; provided that a material
default exists with respect to such Specially Serviced Trust Mortgage Loan. The
Special Servicer shall accept the first offer by a Purchase Option Holder that
is at least equal to the Purchase Price for the subject Trust Mortgage Loan.

          (c) If none of the Purchase Option Holders exercises its option to
purchase any Specially Serviced Trust Mortgage Loan as described in subsection
(b) above, then each Purchase Option Holder will also have the option to
purchase that Specially Serviced Trust Mortgage Loan at a price equal to the
fair value (the "FV Price") of such Specially Serviced Trust Mortgage Loan;
provided that a material default exists with respect to such Specially Serviced
Trust Mortgage Loan. Upon receipt of a request from any Purchase Option Holder
to determine the FV Price in contemplation of its intention to exercise its
option to purchase a Specially Serviced Trust Mortgage Loan as to which a
material default exists at a price that is below the Purchase Price, the Special
Servicer shall promptly obtain an MAI appraisal (the cost of which shall be
covered by a Servicing Advance) of the related Mortgaged Property by an
Independent Appraiser (unless such an appraisal was obtained within one year of
such date and the Special Servicer has no knowledge of any circumstances that
would materially affect the validity of such appraisal). Promptly after
obtaining such appraisal, the Special Servicer shall determine the FV Price for
the subject Specially Serviced Trust Mortgage Loan in accordance with the
Servicing Standard and the provisions of subsection (i) below. Promptly after
determining such FV Price, the Special Servicer shall report such FV Price to
the Trustee and each Purchase Option Holder.

          (d) If the Special Servicer determines that it is willing, or another
Purchase Option Holder notifies the Special Servicer that it is willing, to
purchase any Specially Serviced Trust Mortgage


                                     -226-



Loan as to which a material default exists (the party submitting such bid, the
"Initial Bidder") at a price equal to or above the FV Price (a "FV Bid"), then
the Special Servicer shall notify all other Purchase Option Holders that it has
made or received, as the case may be, such FV Bid (without disclosing the amount
of such FV Bid). All other Purchase Option Holders may submit competing bids
within the ten (10) Business Day period following such notice. At the conclusion
of the above-described ten (10) Business Day period, the Special Servicer shall
accept the highest bid received from any Purchase Option Holder that is at least
equal to the FV Price for the subject Specially Serviced Trust Mortgage Loan.

          (e) If the Special Servicer accepts the bid of any Purchase Option
Holder, such Purchase Option Holder shall be required to purchase the subject
Specially Serviced Trust Mortgage Loan within ten (10) Business Days of receipt
of notice of such acceptance; provided, that neither the Special Servicer nor
any Holder of a Certificate of the Controlling Class shall be liable for the
failure of any assignee whose bid has been accepted by the Special Servicer to
complete any such purchase.

          (f) If the Special Servicer has not accepted a FV Bid prior to the
expiration of 120 days from its determination of the FV Price and thereafter
receives a FV Bid or a request from a Purchase Option Holder for an updated FV
Price, the Special Servicer shall within 45 days recalculate the FV Price (with
no presumption that such FV Price should be reduced on account of the lack of an
FV Bid) and repeat the notice and bidding procedure provided in subsection (d)
above until the purchase option terminates under subsection (j) below.

          (g) If the party exercising the purchase option at the FV Price for
any Specially Serviced Trust Mortgage Loan is the Special Servicer or an
Affiliate thereof, the Trustee shall verify that the FV Price of such Trust
Mortgage Loan is at least equal to the fair value of such Trust Mortgage Loan.
In conducting such verification, the Trustee will be permitted to conclusively
rely on an appraisal obtained by the Trustee from an Independent Appraiser at
the time it is required to verify such FV Price and/or the opinion of an
Independent expert in real estate matters (including the Master Servicer) with
at least five years' experience in valuing or investing in loans, similar to the
subject Specially Serviced Trust Mortgage Loan, that has been selected by the
Trustee with reasonable care at the expense of the Trust Fund.

          (h) Any Purchase Option Holder may, once such purchase option is
exercisable pursuant to this Section 3.18, assign its purchase option with
respect to any Specially Serviced Trust Mortgage Loan to a third party other
than the related Mortgagor or, if such assignment would violate the terms of any
related co-lender, intercreditor or similar agreement, any Affiliate of the
related Mortgagor; and, upon such assignment such third party shall have all of
the rights that had been granted to the Purchase Option Holder hereunder in
respect of the purchase option. Such assignment shall only be effective upon
written notice (together with a copy of the executed assignment and assumption
agreement) being delivered to the Trustee, the Master Servicer and the Special
Servicer. Any Purchase Option Holder that acquires, pursuant to this Section
3.18, a Trust Mortgage Loan that is part of a Loan Combination must satisfy the
requirements for an acceptable transferee under the related Co-Lender Agreement.

          (i) In determining the FV Price for any Specially Serviced Trust
Mortgage Loan under this Section 3.18, the Special Servicer may take into
account, among other factors, the results of any appraisal or updated appraisal
(the cost of which shall constitute a Servicing Advance) that it or the


                                     -227-



Master Servicer may have obtained in accordance with this Agreement within the
prior twelve months; the opinions on fair value expressed by Independent
investors in mortgage loans comparable to the subject Specially Serviced Trust
Mortgage Loan; the period and amount of any delinquency on the subject Specially
Serviced Trust Mortgage Loan; the physical condition of the related Mortgaged
Property; the state of the local economy; and the expected recoveries from the
subject Specially Serviced Trust Mortgage Loan if the Special Servicer were to
pursue a workout or foreclosure strategy instead of selling such Mortgage Loan
to a Purchase Option Holder.

          (j) The purchase option for any Specially Serviced Trust Mortgage Loan
pursuant to this Section 3.18 shall terminate, and shall not be exercisable as
set forth in subsections (b) and (c) above (or if exercised, but the purchase of
such Specially Serviced Mortgage Loan has not yet occurred, shall terminate and
be of no further force or effect) if and when (i) the Special Servicer has
accepted a FV Bid (although the purchase option shall resume if the Person that
submitted that FV Bid does not complete the purchase of the subject Specially
Serviced Trust Mortgage within the time period provided for under Section
3.18(e)), (ii) such Specially Serviced Trust Mortgage Loan has become a
Corrected Mortgage Loan or is otherwise no longer in material default, (iii) the
related Mortgaged Property has become an REO Property, (iv) a Final Recovery
Determination has been made with respect to such Specially Serviced Mortgage
Loan or (v) the subject Specially Serviced Trust Mortgage Loan has been removed
from the Trust Fund.

          (k) Notwithstanding anything herein to the contrary, if and for so
long as an Outside Serviced Trust Mortgage Loan constitutes a "Specially
Serviced Mortgage Loan" (or the equivalent) under the related Outside Servicing
Agreement as to which there exists a material default, then such Outside
Serviced Trust Mortgage Loan shall be deemed a "Specially Serviced Trust
Mortgage Loan" for purposes of, and be subject to the purchase options
contemplated by, Sections 3.18(b) through 3.18(j); provided that the FV Price
described above may be calculated based upon, among other things, appraisals and
other reasonably appropriate information obtained from the related Outside
Servicers under the related Outside Servicing Agreement. If the Special Servicer
has received insufficient information from the applicable Outside Servicer with
respect to any such Outside Serviced Trust Mortgage Loan in order to establish a
FV Price, it will base such determination only on a current Appraisal and on
information otherwise available or reasonably obtainable by it, at the expense
of the Trust. In addition, if the Special Servicer is determining a FV Price
with respect to any Outside Serviced Trust Mortgage Loan and has not received
from the applicable Outside Servicer an appraisal with respect to such Outside
Serviced Trust Mortgage Loan that is dated within the 12 month period prior to
the determination of the FV Price, then the Special Servicer shall obtain, at
the expense of the Trust, a new Appraisal of the subject Mortgaged Property. If
the Special Servicer determines that a FV Price cannot be established for any
such Outside Serviced Trust Mortgage Loan based on the a current Appraisal and
other information available to it, then none of the purchase option holders will
be permitted to exercise the purchase option at a FV Price. In connection with
the foregoing, the Special Servicer shall be entitled to withdraw from the Pool
Custodial Account any out-of-pocket expenses associated with making such FV
Price determination.

          (l) Until such time as a FV Bid is accepted with respect to any
Specially Serviced Trust Mortgage Loan, the Special Servicer shall continue to
pursue all of the other resolution options available to it with respect to such
Specially Serviced Trust Mortgage Loan in accordance with the Servicing
Standard.


                                     -228-



          (m) Any Specially Serviced Trust Mortgage Loan that is purchased
pursuant to the purchase option provided for in this Section 3.18 will remain
subject to any cure and/or purchase rights of any holder of a related mezzanine
loan in connection with a Mortgage Loan default as set forth in the related
intercreditor agreement. Further, any Trust Mortgage Loan that is part of a Loan
Combination and is purchased pursuant to the purchase option provided for in
this Section 3.18 will remain subject to any cure and/or purchase rights of the
related Serviced Non-Trust Mortgage Loan Noteholder(s) provided for under the
related Co-Lender Agreement. In the case of the One New York Plaza Note A-2
Non-Trust Mortgage Loan, in the event the One New York Plaza Loan Combination is
comprised of Specially Serviced Mortgage Loans and the Special Servicer has
determined a FV Price with respect to the One New York Plaza Note A-1 Trust
Mortgage Loan in accordance with this Section 3.18, the Special Servicer shall
provide to the One New York Plaza Note A-2 Non-Trust Mortgage Loan Noteholder
all material information in its possession that has formed the basis of such FV
Price, including the most current Appraisal in its possession.

          (n) The Special Servicer shall use its best efforts to solicit offers
for each Administered REO Property in such manner as will be reasonably likely
to realize a fair price within the time period provided for by Section 3.16(a).
Subject to Section 6.11 and/or Section 6.12, if and as applicable, the Special
Servicer shall accept the first (and, if multiple bids are received
contemporaneously or subsequently, the highest) cash offer received from any
Person that constitutes a fair price for such Administered REO Property. If the
Special Servicer reasonably believes that it will be unable to realize a fair
price for any Administered REO Property within the time constraints imposed by
Section 3.16(a), then (subject to Section 6.11 and/or Section 6.12, in each case
if and as applicable) the Special Servicer shall dispose of such Administered
REO Property upon such terms and conditions as the Special Servicer shall deem
necessary and desirable to maximize the recovery thereon under the circumstances
and, in connection therewith, shall accept the highest outstanding cash bid,
regardless of from whom received.

          (o) The Special Servicer shall give the Trustee and the Depositor
prior written notice of its intention to sell any Administered REO Property
pursuant to this Section 3.18.

          (p) No Interested Person shall be obligated to submit an offer to
purchase any Administered REO Property, and notwithstanding anything to the
contrary herein, neither the Trustee, in its individual capacity, nor any of its
Affiliates may bid for or purchase any Administered REO Property pursuant
hereto.

          (q) Whether any cash offer constitutes a fair price for any
Administered REO Property for purposes of this Section 3.18, shall be determined
by the Special Servicer or, if such cash offer is from the Special Servicer or
an Affiliate of the Special Servicer, by the Trustee. In determining whether any
offer received from the Special Servicer or an Affiliate of the Special Servicer
represents a fair price for any Administered REO Property, the Trustee shall be
supplied with and shall be entitled to rely on the most recent appraisal in the
related Servicing File conducted in accordance with this Agreement within the
preceding 12-month period (or, in the absence of any such appraisal or if there
has been a material change at the subject Administered REO Property since any
such appraisal, on a new appraisal to be obtained by the Special Servicer (the
cost of which shall be covered by, and be reimbursable as, a Servicing
Advance)). The appraiser conducting any such new appraisal shall be an
Independent Appraiser selected by the Special Servicer if neither the Special
Servicer nor any Affiliate thereof is bidding with respect to an Administered
REO Property and selected by the Trustee if either


                                     -229-



the Special Servicer or any Affiliate thereof is so bidding. Where any
Interested Person is among those bidding with respect to an Administered REO
Property, the Special Servicer shall require that all offers be submitted to it
(and, if the Special Servicer or any Affiliate thereof is bidding, to the
Trustee) in writing and be accompanied by a refundable deposit of cash in an
amount equal to 5% of the offer amount. In determining whether any offer from a
Person other than itself or one of its Affiliates constitutes a fair price for
any Administered REO Property, the Special Servicer shall take into account the
results of any appraisal or updated appraisal that it or the Master Servicer may
have obtained in accordance with this Agreement within the prior twelve months,
and any Independent Appraiser shall be instructed to take into account, as
applicable, among other factors, the occupancy level and physical condition of
the subject Administered REO Property, the state of the local economy and the
obligation to dispose of the subject Administered REO Property within the time
period specified in Section 3.16(a). The Purchase Price for any Administered REO
Property shall in all cases be deemed a fair price. Notwithstanding the other
provisions of this Section 3.18, no cash offer from the Special Servicer or any
Affiliate thereof shall constitute a fair price for any Administered REO
Property unless such offer is the highest cash offer received and at least two
independent offers (not including the offer of the Special Servicer or any
Affiliate thereof) have been received. In the event the offer of the Special
Servicer or any Affiliate thereof is the only offer received or is the higher of
only two offers received, then additional offers shall be solicited. If an
additional offer or offers, as the case may be, are received and the original
offer of the Special Servicer or any Affiliate thereof is the highest of all
cash offers received, then the offer of the Special Servicer or such Affiliate
shall be accepted, provided that the Trustee has otherwise determined, as
provided above in this Section 3.18(q), that such offer constitutes a fair price
for any Administered REO Property. Any offer by the Special Servicer shall be
unconditional; and, if accepted, the subject Administered REO Property shall be
transferred to the Special Servicer without recourse, representation or warranty
other than customary representations as to title given in connection with the
sale of a real property.

          (r) Subject to Sections 3.18(a) through 3.18(q) above, and further
subject to Section 6.11 and/or Section 6.12, in each case if and as applicable,
the Special Servicer shall act on behalf of the Trustee in negotiating with
independent third parties seeking to purchase an Administered REO Property and
taking any other action necessary or appropriate in connection with the sale of
any Specially Serviced Trust Mortgage Loan or Administered REO Property pursuant
to this Section 3.18, and the collection of all amounts payable in connection
therewith. In connection therewith, the Special Servicer may charge prospective
bidders for any Administered REO Property, and may retain, fees that approximate
the Special Servicer's actual costs in the preparation and delivery of
information pertaining to, or evaluating bids for, such Administered REO
Property without obligation to deposit such amounts into any Custodial Account.
Any sale of a Specially Serviced Trust Mortgage Loan or an Administered REO
Property pursuant to this Section 3.18 shall be final and without recourse to
the Trustee or the Trust, and if such sale is consummated in accordance with the
terms of this Agreement, neither the Special Servicer nor the Trustee shall have
any liability to any Certificateholder with respect to the purchase price
therefor accepted by the Special Servicer or the Trustee.

          (s) Any sale of a Specially Serviced Trust Mortgage Loan or an
Administered REO Property pursuant to this Section 3.18 shall be for cash only
and shall be on a servicing released basis.


                                     -230-



          SECTION 3.19.  Additional Obligations of the Master Servicer and
                         Special Servicer; Obligations to Notify Ground Lessors
                         and Hospitality Franchisors; the Special Servicer's
                         Right to Request the Master Servicer to Make Servicing
                         Advances; Mortgagor Enforcement Actions.

          (a) The Master Servicer shall deliver to the Trustee for deposit in
the Collection Account on each Trust Master Servicer Remittance Date, without
any right of reimbursement therefor, an amount equal to the lesser of: (i) the
aggregate amount of all Prepayment Interest Shortfalls, if any, incurred in
connection with Principal Prepayments Received by the Trust, during the most
recently ended applicable Collection Period, with respect to Performing Serviced
Trust Mortgage Loans and, if it constitutes a "Performing Serviced Mortgage
Loan" (or the equivalent) under the related Outside Servicing Agreement, any
Outside Serviced Trust Mortgage Loan; and (ii) the sum of (1) the aggregate of
all Master Servicing Fees received by the Master Servicer during such Collection
Period with respect to the entire Mortgage Pool (but only to the extent of that
portion thereof calculated at a rate of 0.01% per annum with respect to each and
every Trust Mortgage Loan and REO Trust Mortgage Loan) and (2) the aggregate
amount of Prepayment Interest Excesses received in respect of the entire
Mortgage Pool during such Collection Period; provided, however, that if any
Prepayment Interest Shortfall occurs with respect to any Serviced Trust Mortgage
Loan as a result of the Master Servicer's allowing the Mortgagor to deviate from
the terms of the related loan documents regarding principal prepayments, the
Master Servicer shall be obligated to pay an amount equal to the entire
Prepayment Interest Shortfall with respect to the subject Serviced Trust
Mortgage Loan without any limitation of the kind set forth in clauses (1) and
(2) above.

          (b) The Master Servicer shall, as to each Serviced Trust Mortgage Loan
which is secured by the interest of the related Mortgagor under a Ground Lease,
even if the corresponding fee interest is encumbered, promptly (and in any event
within 60 days) following the Closing Date, notify the related ground lessor of
the transfer of such Serviced Trust Mortgage Loan to the Trust Fund pursuant to
this Agreement and inform such ground lessor that any notices of default under
the related Ground Lease should thereafter be forwarded to the Master Servicer.

          (c) The Master Servicer shall, as to each Serviced Trust Mortgage Loan
which is secured by the interest of the related Mortgagor in a hospitality
property (as identified on Schedule VI hereto), not later than the later of (i)
30 days following the Master Servicer's receipt of the subject franchise
agreement and (ii) the expiration of the period that may be required for such
notice pursuant to the terms of the applicable franchise documents, if any,
notify the related hospitality franchisor of the transfer of such Serviced Trust
Mortgage Loan to the Trust Fund pursuant to this Agreement and inform such
hospitality franchisor that any notices of default under the related franchise
agreement should thereafter be forwarded to the Master Servicer.

          (d) Notwithstanding anything to the contrary contained in this
Agreement, if the Special Servicer is required under this Agreement to make any
Servicing Advance but does not desire to do so, the Special Servicer may, in its
sole discretion, request that the Master Servicer make such Servicing Advance,
such request to be made, in writing, at least five (5) Business Days (or, in an
emergency situation or on an urgent basis, two (2) Business Days, provided that
the written request sets forth the nature of the emergency or the basis of the
urgency) in advance of the date on which such Servicing Advance is required to
be made hereunder and to be accompanied by such information and


                                     -231-



documentation regarding the subject Servicing Advance as the Master Servicer may
reasonably request. The Master Servicer shall have the obligation to make any
such Servicing Advance that it is so requested by the Special Servicer to make,
within five (5) Business Days (or, in an emergency situation or on an urgent
basis, two (2) Business Days) of the Master Servicer's receipt of such request.
If the request is timely and properly made, the Special Servicer shall be
relieved of any obligations with respect to a Servicing Advance that it so
requests the Master Servicer to make (regardless of whether or not the Master
Servicer shall make such Servicing Advance). The Master Servicer shall be
entitled to reimbursement for any Servicing Advance made by it at the direction
of the Special Servicer, together with interest thereon in accordance with
Sections 3.05(a) or 3.05A and/or 3.11(g), as applicable, at the same time, in
the same manner and to the same extent as the Master Servicer is entitled with
respect to any other Servicing Advances made thereby.

          Notwithstanding the foregoing provisions of this Section 3.19(d), the
Master Servicer shall not be required to make at the direction of the Special
Servicer, any Servicing Advance if the Master Servicer determines in its
reasonable, good faith judgment that such Servicing Advance, although not
characterized by the Special Servicer as a Nonrecoverable Servicing Advance, is
in fact a Nonrecoverable Servicing Advance. The Master Servicer shall notify the
Special Servicer in writing of such determination, which shall be made pursuant
to Section 3.11(h). Any request by the Special Servicer that the Master Servicer
make a Servicing Advance shall be deemed to be a determination by the Special
Servicer that such requested Servicing Advance is not a Nonrecoverable Servicing
Advance, and the Master Servicer, the Trustee and any Fiscal Agent shall be
entitled to conclusively rely on such determination. Upon making a
determination, in accordance with the applicable requirements under Section
3.11(h), that any Servicing Advance previously made or proposed to be made with
respect to a Specially Serviced Mortgage Loan or an Administered REO Property is
a Nonrecoverable Servicing Advance, the Special Servicer shall report its
determination to the Master Servicer and the Trustee. The Master Servicer shall
be entitled to conclusively rely on such a determination by the Special
Servicer.

          (e) The Master Servicer (if a Performing Serviced Trust Mortgage Loan
is involved) and the Special Servicer (if a Specially Serviced Trust Mortgage
Loan or an REO Trust Mortgage Loan is involved) shall each be responsible for:
(i) providing on a timely basis to any lender of any related mezzanine debt such
notices (including with respect to Mortgage Loan defaults), reports and other
information as may be required from the Trust, as holder of any Trust Mortgage
Loan, under any related co-lender, intercreditor or similar agreement; and (ii)
otherwise taking such actions as are required under or contemplated by the
related co-lender, intercreditor or similar agreement to permit any lender of
related mezzanine debt to exercise any purchase option or cure rights that it
may have with respect to any Trust Mortgage Loan under such related co-lender,
intercreditor or similar agreement.

          (f) Upon termination of the Trust Fund, any funds or other assets
remaining in the Loss of Value Reserve Fund, to the extent not otherwise
required to be part of the Available Distribution Amount for the Final
Distribution Date in accordance with Section 3.05(e), shall be distributed to
the Holder or Holders of the Class R-III Certificates. The Trustee and the
Special Servicer shall account for the Loss of Value Reserve Fund as an outside
reserve fund within the meaning of Treasury regulations section 1.860G-2(h) and
not an asset of any REMIC Pool or the Grantor Trust (if created hereunder taking
into account Section 2.05(b)). Furthermore, for all federal tax purposes, the
Trustee and the Special Servicer shall treat: (i) any amounts paid out of the
Loss of Value Reserve Fund to the Certificateholders as distributions by the
REMIC Pools for all federal tax purposes; and (ii) any amounts transferred by a
REMIC Pool to the Loss of Value Reserve Fund as amounts distributed by such
REMIC


                                     -232-



Pool to the beneficial owner of the Loss of Value Reserve Fund. The Holder or
Holders of the Class R-III Certificates will be the sole beneficial owner(s) of
the Loss of Value Reserve Fund for all income and franchise tax purposes.

          (g) [RESERVED.]

          (h) In connection with a mediation and/or arbitration proceeding
conducted in accordance with Section 2.03(i) hereof or Section 5(i) of the
UBS/Depositor Mortgage Loan Purchase Agreement, as the case may be, in the event
that the Master Servicer is the party acting on behalf of the Trust in such
mediation and/or arbitration proceeding and such mediation and/or arbitration
proceeding relates to a Specially Serviced Trust Mortgage Loan, the Master
Servicer shall consult with the Special Servicer prior to consenting to or
entering into any final resolution, settlement or agreement with respect
thereto.

          (i) Without the prior written consent of the applicable Mortgage Loan
Seller, the Master Servicing Group (as defined below) shall not disclose to any
Person employed by the Master Servicer or an affiliate thereof that is part of a
business unit that originates or refinances mortgage loans any information that
the Master Servicing Group has received or obtained or generated or is otherwise
in its possession as a result of its acting as Master Servicer hereunder. In
addition, without the prior written consent of the applicable Mortgage Loan
Seller, the Master Servicing Group shall not take any direct action, nor will it
direct a third party to take any action, to refinance or solicit the refinancing
of any Mortgage Loan. For purposes of this Section 3.19(i), the "Master
Servicing Group" shall mean the business unit of the Master Servicer (which,
with respect to Wachovia Bank, National Association, is called Commercial Real
Estate Services) that is in the business of master servicing and/or primary
servicing commercial mortgage loans that are in securitizations. Notwithstanding
the foregoing, the following shall not constitute violations of this Section
3.19(i): (i) dissemination of information or reports as contemplated by this
Agreement, (ii) promotions undertaken by the Master Servicer or any Affiliate of
the Master Servicer which are directed to commercial mortgage loan borrowers,
originators and mortgage brokers generally, which promotions, in each case, are
based upon information that has been acquired from a source other than the
Master Servicing Group, including, without limitation, commercially acquired
mailing lists or information generally available in the public domain, (iii)
actions taken in connection with serving the refinancing needs of a Mortgagor
who, without such solicitation by the Master Servicer as described in the second
preceding sentence, contacts the Master Servicer in connection with the
refinance of such Mortgage Loan, or (iv) actions taken or communications made by
the Master Servicing Group in connection with the sale or refinance of a
Specially Serviced Mortgage Loan.

          (j) If any Serviced Mortgage Loan provides that the applicable grace
period during which any Monthly Payment is due (without giving rise to a
default) does not commence until after notice is given to the related Mortgagor,
then the Master Servicer shall monitor the receipt of all Monthly Payments with
respect to such Mortgage Loan. If any such Monthly Payment on any such Mortgage
Loan is not received by the related Due Date, then the Master Servicer shall use
reasonable efforts to provide, in accordance with the Servicing Standard, as
soon as reasonably practicable, written notice of such failure to the related
Mortgagor sufficient to cause the commencement of the applicable grace period.


                                     -233-



          SECTION 3.20.  Modifications, Waivers, Amendments and Consents;
                         Defeasance.

          (a) Subject to Sections 3.20(b) through 3.20(f) and 3.20(m) below, and
further subject to Section 6.11 and/or Section 6.12, in each case if and as
applicable, and any related intercreditor, co-lender or similar agreement
(including, in the case of a Mortgage Loan that is part of a Serviced Loan
Combination, the related Co-Lender Agreement), the Special Servicer (or, under
the limited circumstances set forth in Section 3.20(c), the Master Servicer)
may, on behalf of the Trustee and, in the case of a Serviced Non-Trust Mortgage
Loan, the related Serviced Non-Trust Mortgage Loan Noteholder, agree to any
modification, extension, waiver or amendment of any term of any Serviced
Mortgage Loan and respond to various Mortgagor requests for consent on the part
of the mortgagee (including the lease reviews and lease consents related
thereto), without the consent of the Trustee, any Certificateholder, any
Serviced Non-Trust Mortgage Loan Noteholder, the Master Servicer (in the case of
any such action taken by the Special Servicer) or, except as expressly set forth
below, the Special Servicer (in the case of any such action taken by the Master
Servicer). Neither the Master Servicer nor the Special Servicer (in its capacity
as such) may agree with the related Mortgagor to any modification, extension,
waiver or amendment of an Outside Serviced Mortgage Loan.

          (b) All modifications, extensions, waivers or amendments of any
Serviced Mortgage Loan, including the lease reviews and lease consents related
thereto, shall be in writing and shall be considered and effected in a manner
consistent with the Servicing Standard. All modifications, extensions, waivers
or amendments of a Co-Lender Agreement shall be in writing and shall be
considered and effected in a manner consistent with the Servicing Standard.

          (c) In the case of any Performing Serviced Mortgage Loan, and subject
to the rights of the Special Servicer set forth below, the Master Servicer shall
(without the consent of the Trustee, any Certificateholder, any Loan-Specific
Class Representative, any Serviced Non-Trust Mortgage Loan Noteholder or, except
as expressly set forth below, the Special Servicer), be responsible for the
following:

               (i) approving routine leasing activity (including any
     subordination, standstill and attornment agreements) with respect to any
     lease for less than the lesser of (A) 20,000 square feet and (B) 20% of the
     related Mortgaged Property;

               (ii) approving a change of the property manager at the request of
     the related Mortgagor, provided that (A) the successor property manager is
     not affiliated with the Mortgagor and is a nationally or regionally
     recognized manager of similar properties, (B) the subject Mortgage Loan
     does not have an outstanding principal balance in excess of $5,000,000 and
     (C) the subject Mortgaged Property does not secure a Loan Combination;

               (iii) approving any waiver affecting the timing of receipt of
     financial statements from any Mortgagor, provided that such financial
     statements are delivered no less than quarterly and within 60 days of the
     end of the calendar quarter;

               (iv) approving annual budgets for the related Mortgaged Property;
     provided that no such budget (A) provides for the payment of operating
     expenses in an amount equal to more than 110% of the amounts budgeted
     therefor for the prior year or (B) provides for the payment of any material
     expenses to any affiliate of the Mortgagor (other than the payment of a


                                     -234-



     management fee to any property manager if such management fee is no more
     than the management fee in effect on the Cut-off Date);

               (v) subject to other restrictions herein regarding Principal
     Prepayments, waiving any provision of a Mortgage Loan requiring a specified
     number of days notice prior to a Principal Prepayment;

               (vi) approving modifications, consents or waivers (other than
     those set forth in Sections 3.20(d) and (e)) in connection with a
     defeasance permitted by the terms of the subject Mortgage Loan if the
     Master Servicer receives an Opinion of Counsel (which Opinion of Counsel
     shall be an expense of the Mortgagor) to the effect that such modification,
     waiver or consent would not cause any REMIC Pool to fail to qualify as a
     REMIC under the Code or result in a "prohibited transaction" under the
     REMIC Provisions; provided that the Master Servicer shall not approve any
     modification that would reduce the amount of the Defeasance Collateral
     required to be delivered in connection with any such defeasance; and

               (vii) consenting to subject the related Mortgaged Property to an
     easement or right-of-way for utilities, access, parking, public
     improvements or another purpose, and consenting to subordination of the
     related Mortgage Loan to such easement or right-of way provided the Master
     Servicer shall have determined in accordance with the Servicing Standard
     that such easement or right-of-way shall not materially interfere with the
     then-current use of the related Mortgaged Property, or the security
     intended to be provided by such Mortgage, the related Mortgagor's ability
     to repay the Mortgage Loan, or materially or adversely affect the value of
     such Mortgaged Property or cause the Mortgage Loan to cease to be a
     "qualified mortgage" for REMIC purposes;

provided that, (1) any such modification, waiver or amendment would not in any
way affect a payment term (including (except as provided in Section 3.20(o)
below) a waiver of the payment of assumption fees) of the subject Performing
Serviced Mortgage Loan (other than in the case of a waiver of the payment of
Default Charges), (2) agreeing to such modification, waiver or amendment would
be consistent with the Servicing Standard, (3) agreeing to such modification,
waiver or amendment will not violate the terms, provisions or limitations of
this Agreement, and (4) any such modification, waiver or amendment does not
materially violate the terms, conditions and limitations of Section 3.08, if
applicable. With respect to any action proposed to be taken by the Master
Servicer under this Section 3.20(c) where any thresholds in clauses (i) through
(vii) of the preceding sentence are exceeded, or which cannot be taken by the
Master Servicer by reason of the proviso to the previous sentence, the Special
Servicer only may take such action (if and to the extent otherwise permitted
under this Agreement).

          For the avoidance of doubt, and without limiting the generality of the
foregoing, any request for the disbursement of earnouts or holdback amounts with
respect to any Earnout Trust Mortgage Loan received by the Master Servicer shall
be submitted to the Special Servicer for approval (which approval shall be
deemed given if the request is not denied by the Special Servicer in writing to
the Master Servicer within five (5) Business Days of the Special Servicer's
receipt of such request). For purposes of this Agreement, "disbursement of
earnouts or holdback amounts" shall mean the disbursement or funding to a
Mortgagor of previously unfunded, escrowed or otherwise reserved portions of the
loan proceeds of the applicable Mortgage Loan until certain conditions precedent
thereto relating to the

satisfaction of performance-related criteria (i.e., project reserve thresholds,
lease-up requirements, sale requirements, etc.) as set forth in the applicable
Mortgage Loan documents, have been satisfied.

          Except as permitted by Section 3.02(a), Section 3.03(d), Section 3.07,
Section 3.08(a), this Section 3.20(c), Section 3.20(m) and Section 3.20(o), the
Master Servicer may not agree to waive, modify or amend any term of any Serviced
Mortgage Loan (including allowing the Mortgagor to deviate from the terms of the
related loan documents regarding principal prepayments) or respond to any
Mortgagor requests for mortgagee consent and shall forward such requests to the
Special Servicer. Furthermore, the Master Servicer may not agree to any
modification, extension, waiver or amendment of any term of any Serviced
Mortgage Loan that would cause an Adverse REMIC Event with respect to any REMIC
Pool or an Adverse Grantor Trust Event with respect to the Grantor Trust (if
created hereunder taking into account Section 2.05(b)).

          (d) Except as provided in Section 3.02(a), Section 3.07, Section 3.08,
Section 3.20(e), Section 3.20(m) and Section 3.20(o), the Special Servicer, on
behalf of the Trustee or, in the case of a Serviced Non-Trust Mortgage Loan, the
related Serviced Non-Trust Mortgage Loan Noteholder, shall not agree or consent
to any modification, extension, waiver or amendment of any term of any Serviced
Mortgage Loan that would:

               (i) affect the amount or timing of any scheduled payment of
     principal, interest or other amount (including Prepayment Premiums or Yield
     Maintenance Charges, but excluding Default Interest and, subject to Section
     3.20(o), other amounts payable as additional servicing compensation)
     payable thereunder;

               (ii) affect the obligation of the related Mortgagor to pay a
     Prepayment Premium or Yield Maintenance Charge, or effectuate the waiver of
     any prepayment restriction thereunder or permit a Principal Prepayment
     during any period in which the related loan documents prohibit Principal
     Prepayments;

               (iii) except as expressly contemplated by the related Mortgage or
     pursuant to Section 3.09(d), result in a release of the lien of the
     Mortgage on any material portion of the related Mortgaged Property without
     a corresponding Principal Prepayment in an amount not less than the fair
     market value (as determined by an appraisal by an Independent Appraiser
     delivered to the Special Servicer at the expense of the related Mortgagor
     and upon which the Special Servicer may conclusively rely) of the property
     to be released; or

               (iv) in the reasonable, good faith judgment of the Special
     Servicer, otherwise materially impair the security for such Mortgage Loan
     or reduce the likelihood of timely payment of amounts due thereon.

          Furthermore, the Special Servicer may not agree to any modification,
extension, waiver or amendment of any term of any Serviced Mortgage Loan that
would cause an Adverse REMIC Event with respect to any REMIC Pool or an Adverse
Grantor Trust Event with respect to the Grantor Trust (if created hereunder
taking into account Section 2.05(b)).


                                      -236-



          (e) Notwithstanding Section 3.20(d), but subject to Section 3.20(o),
Section 6.11 and/or Section 6.12, in each case if and as applicable, and the
second and third paragraphs of this Section 3.20(e), the Special Servicer may--

               (i) reduce the amounts owing under any Specially Serviced
     Mortgage Loan by forgiving principal, accrued interest (including
     Additional Interest) or any Prepayment Premium or Yield Maintenance Charge,

               (ii) reduce the amount of the Monthly Payment on any Specially
     Serviced Mortgage Loan, including by way of a reduction in the related
     Mortgage Rate,

               (iii) forbear in the enforcement of any right granted under any
     Mortgage Note, Mortgage or other loan document relating to a Specially
     Serviced Mortgage Loan,

               (iv) accept a Principal Prepayment on any Specially Serviced
     Mortgage Loan during any Lockout Period, or

               (v) extend the maturity of any Specially Serviced Mortgage Loan;

provided that (A) the related Mortgagor is in monetary default or material
non-monetary default with respect to such Specially Serviced Mortgage Loan or,
in the reasonable, good faith judgment of the Special Servicer, such default is
reasonably foreseeable, (B) in the reasonable, good faith judgment of the
Special Servicer, such modification, extension, waiver or amendment would
increase the recovery on such Specially Serviced Mortgage Loan to
Certificateholders (as a collective whole) or, if a Serviced Loan Combination is
involved, would increase the recovery on such Loan Combination to
Certificateholders and the related Serviced Non-Trust Mortgage Loan
Noteholder(s) (as a collective whole), on a present value basis (the relevant
discounting of anticipated collections that will be distributable to the
Certificateholders (or, in the case of a Serviced Loan Combination, to
Certificateholders and the related Non-Trust Mortgage Loan Noteholder(s)), to be
performed at the related Mortgage Rate(s)), and (C) such modification,
extension, waiver or amendment would not cause an Adverse REMIC Event in respect
of any REMIC Pool or an Adverse Grantor Trust Event with respect to the Grantor
Trust (if created hereunder taking into account Section 2.05(b)); and provided,
further, that any modification, extension, waiver or amendment of the payment
terms of a Serviced Loan Combination shall be structured so as to be consistent
with the allocation and payment priorities set forth in the related loan
documents and the related Co-Lender Agreement, such that neither the Trust, as
holder of the Trust Mortgage Loan that constitutes part of that Serviced Loan
Combination, on the one hand, nor any of the related Serviced Non-Trust Mortgage
Loan Noteholders, on the other hand, shall gain a priority over any other such
holder with respect to any payment, which priority is not, as of the date of the
related Co-Lender Agreement, reflected in such loan documents and such Co-Lender
Agreement; and provided, further, that, with respect to any Serviced Loan
Combination, to the extent consistent with the Servicing Standard (taking into
account the extent to which any Serviced Subordinate Non-Trust Mortgage Loan
that is part of such Serviced Loan Combination is junior to the Trust Mortgage
Loan and any Pari Passu Non-Trust Mortgage Loan that is part of the same
Serviced Loan Combination), (1) no waiver, reduction or deferral of any
particular amounts due on the Trust Mortgage Loan or any Pari Passu Non-Trust
Mortgage Loan that is part of such Serviced Loan Combination shall be effected
prior to the waiver, reduction or deferral of the entire corresponding item in
respect of each Serviced Subordinate Non-Trust Mortgage Loan, if any, that is
part of such Serviced Loan Combination, and (2) no reduction of the Mortgage
Rate on the Trust Mortgage Loan or any Pari


                                      -237-



Passu Non-Trust Mortgage Loan that is part of such Serviced Loan Combination
shall be effected prior to the reduction of the Mortgage Rate on each Serviced
Subordinate Non-Trust Mortgage Loan, if any, that is part of such Serviced Loan
Combination, to the fullest extent possible. In the case of every other
modification, waiver or consent, the Special Servicer shall determine and may
rely on an Opinion of Counsel (which Opinion of Counsel shall be an expense of
the Trust Fund to the extent not paid by the related Mortgagor) to the effect
that such modification, waiver or amendment would not either (1) effect an
exchange or reissuance of the Mortgage Loan under Treasury regulations section
1.860G-2(b) of the Code or (2) cause any REMIC Pool to fail to qualify as a
REMIC under the Code or result in the imposition of any tax on "prohibited
transactions" or "contributions" after the Startup Day under the REMIC
Provisions or (3) result in an Adverse Grantor Trust Event.

          Notwithstanding the foregoing, in no event shall the Special Servicer:
(i) extend the maturity date of a Serviced Mortgage Loan beyond the date that is
two years prior to the last Rated Final Distribution Date for the Pool-Based
Certificates; (ii) extend the maturity date of any Serviced Mortgage Loan for
more than five years beyond its Stated Maturity Date or, in the case of the
Sturbridge Commons Trust Mortgage Loan, extend the maturity date of such Trust
Mortgage Loan beyond the date that is five years prior to the Rated Final
Distribution Date for the Class SBC Certificates (exclusive of the Class SBC-15
Certificates); or (iii) if the subject Serviced Mortgage Loan is secured solely
or primarily by a Mortgage on the leasehold interest under a Ground Lease (but
not the related fee interest), extend the maturity date of such Serviced
Mortgage Loan beyond the date which is 20 years (or, to the extent consistent
with the Servicing Standard, giving due consideration to the remaining term of
the Ground Lease, 10 years) prior to the expiration of the term of such Ground
Lease.

          The determination of the Special Servicer contemplated by clause (B)
of the proviso to the first paragraph of this Section 3.20(e) shall be evidenced
by an Officer's Certificate to such effect delivered to the Trustee and the
Master Servicer (and, in the case of a Serviced Loan Combination, the related
Serviced Non-Trust Mortgage Loan Noteholder(s)) and describing in reasonable
detail the basis for the Special Servicer's determination. The Special Servicer
shall attach to such Officer's Certificate any information including but not
limited to income and expense statements, rent rolls, property inspection
reports and appraisals that support such determination.

          (f) Notwithstanding anything to the contrary in this Agreement, none
of the Trustee, the Master Servicer or the Special Servicer, as applicable,
shall give any consent, approval or direction regarding the termination of the
related property manager or the designation of any replacement property manager
or, if such Mortgaged Property is hospitality property, give any consent,
approval or direction regarding the termination of the franchise or the
designation of a new franchise, with respect to any Mortgaged Property that
secures a Serviced Trust Mortgage Loan that has an unpaid principal balance that
is at least equal to the lesser of $20,000,000 and 2% of the then aggregate
principal balance of the Mortgage Pool, unless: (1) the mortgagee is not given
discretion under the terms of the related Mortgage Loan to withhold its consent;
or (2) it has received prior written confirmation from each Rating Agency (and,
if applicable in connection with a Serviced Loan Combination that includes a
Specially Designated Securitized Non-Trust Mortgage Loan, Fitch) that such
action will not result in an Adverse Rating Event with respect to any Class of
Certificates or class of Specially Designated Non-Trust Mortgage Loan Securities
rated by such rating agency.

          Any party hereto seeking rating agency confirmation with respect to
the matters described above shall deliver a Review Package to such rating
agency.


                                      -238-



          (g) Any payment of interest that is deferred pursuant to any
modification, extension, waiver or amendment permitted hereunder, shall not, for
purposes hereof, including calculating monthly distributions to
Certificateholders, be added to the unpaid principal balance or Stated Principal
Balance of the related Serviced Mortgage Loan, notwithstanding that the terms of
such modification, extension, waiver or amendment so permit. The foregoing shall
in no way limit the Special Servicer's ability to charge and collect from the
Mortgagor costs otherwise collectible under the terms of the related Mortgage
Note.

          (h) The Special Servicer or Master Servicer may, as a condition to
granting any request by a Mortgagor for consent, modification, extension, waiver
or indulgence or any other matter or thing, the granting of which is within its
discretion pursuant to the terms of the instruments evidencing or securing the
related Serviced Mortgage Loan and, further, by the terms of this Agreement and
applicable law, require that such Mortgagor pay to it (i) as additional
servicing compensation, a reasonable or customary fee for the additional
services performed in connection with such request, and (ii) any related costs
and expenses incurred by it. Any such fee that is to be shared by the Master
Servicer and the Special Servicer may not be waived or reduced by either such
party without the consent of the other party. In no event shall the Special
Servicer or Master Servicer be entitled to payment for such fees or expenses
unless such payment is collected from the related Mortgagor.

          (i) The Special Servicer and Master Servicer shall each notify the
other, any related Sub-Servicers, the Trustee and, if a Serviced Non-Trust
Mortgage Loan is affected, the related Serviced Non-Trust Mortgage Loan
Noteholder, in writing, of any modification, extension, waiver or amendment of
any term of any Serviced Mortgage Loan (including fees charged the Mortgagor)
agreed to by it and the date thereof, and shall deliver to the Trustee or any
related Custodian for deposit in the related Mortgage File (with a copy to be
delivered to or retained by, as applicable, the Master Servicer) and, if a
Serviced Non-Trust Mortgage Loan is affected, the related Serviced Non-Trust
Mortgage Loan Noteholder)), an executed counterpart of the agreement relating to
such modification, extension, waiver or amendment promptly following execution
and delivery thereof, to be followed by an original recorded counterpart
promptly following the recordation (and receipt) thereof.

          (j) To the extent that either the Master Servicer or Special Servicer
waives any Default Charge in respect of any Serviced Mortgage Loan, whether
pursuant to Section 3.02(a) or this Section 3.20, the respective amounts of
additional servicing compensation payable to the Master Servicer and the Special
Servicer as Net Default Charges out of such Default Charges shall be reduced
proportionately based upon the respective amounts that would have been payable
thereto as Net Default Charges out of such Default Charges if such waiver had
not been granted.

          (k) If, with respect to any Serviced Mortgage Loan (1) under which the
lender can require defeasance in lieu of prepayment, or (2) that permits
defeasance, the Master Servicer shall receive a notice from the related
Mortgagor that it intends to prepay or defease, as applicable, such Serviced
Mortgage Loan in accordance with the terms thereof, then the Master Servicer
shall, subject to the next paragraph and the related loan documents, (i) only in
the case of a Serviced Mortgage Loan under clause (1) above, promptly respond to
such notice in a manner which would require that the Mortgagor pledge Defeasance
Collateral in lieu of such prepayment pursuant to the terms of the related
Mortgage Note, and (ii) notify each Rating Agency, the Trustee, the Underwriters
and the Special Servicer of the intent to defease such Mortgage Loan, and (iii)
upon the written confirmation from each Rating Agency (and, if applicable, if a
Serviced Loan Combination that includes a Specially Designated


                                      -239-



Securitized Non-Trust Mortgage Loan is involved, and any related Specially
Designated Non-Trust Mortgage Loan Securities are rated by Fitch, from Fitch)
that the acceptance of a pledge of the Defeasance Collateral (or, in the case of
a Serviced Mortgage Loan under clause (1) above, that the acceptance of a pledge
of the Defeasance Collateral in lieu of a full prepayment) will not result in an
Adverse Rating Event with respect to any Class of Certificates or class of
Specially Designated Non-Trust Mortgage Loan Securities rated by such rating
agency, take such further action as provided in such Mortgage Note to effectuate
such defeasance, including the purchase and perfection of the Defeasance
Collateral on behalf of the Trustee (as mortgagee of record on behalf of the
Certificateholders and, in the case of a Serviced Loan Combination, the affected
Serviced Non-Trust Mortgage Loan Noteholder(s)); provided that the written
confirmation contemplated by clause (iii) above shall not be required (A) from
S&P in the case of a Serviced Trust Mortgage Loan (1) with an unpaid principal
balance less than or equal to $20,000,000, (2) that constitutes less than 5% of
the aggregate unpaid principal balance of the Mortgage Pool and (3) that does
not then constitute one of the ten largest (measured by unpaid principal
balance) Trust Mortgage Loans in the Mortgage Pool, so long as, in lieu of
obtaining such written confirmation from S&P, the Master Servicer delivers to
S&P a certification in the form attached hereto as Exhibit M (a "Defeasance
Certificate"), or (B) from Moody's in the case of any Serviced Trust Mortgage
Loan (1) with an unpaid principal balance less than or equal to $25,000,000, (2)
that constitutes less than 5% of the aggregate unpaid principal balance of the
Mortgage Pool and (3) that does not then constitute one of the ten largest
(measured by unpaid principal balance) Trust Mortgage Loans in the Mortgage
Pool, so long as, in lieu of obtaining such written confirmation from Moody's,
the Master Servicer delivers to Moody's a Defeasance Certificate; and provided,
further, that, the written confirmation contemplated by clause (iii) above shall
not be required from S&P and/or Moody's (provided the Master Servicer delivers a
Defeasance Certificate to the applicable Rating Agency), as applicable, in the
event the subject Serviced Trust Mortgage Loan complies with the then current
applicable guidelines set forth by such Rating Agency, or the unpaid principal
balance of the subject Serviced Trust Mortgage Loan, the percentage the subject
Serviced Trust Mortgage Loan constitutes of the Mortgage Pool or the relative
size of the subject Serviced Trust Mortgage Loan with respect to the Mortgage
Pool, as applicable, does not exceed the then current applicable threshold for
review as set forth by such Rating Agency.

          Notwithstanding the foregoing, but subject to the related loan
documents, the Master Servicer shall not permit a pledge of Defeasance
Collateral under any Serviced Mortgage Loan that is also a Defeasance Mortgage
Loan if (i) such defeasance would occur within two years of the Startup Day,
(ii) the defeasance collateral shall not be Government Securities, (iii) an
opinion of counsel confirming that the Trustee has a first priority security
interest in the Defeasance Collateral is not delivered, (iv) the defeased note
is not held by a special purpose entity with no material assets other than
Defeasance Collateral, (v) a certification from a firm of independent public
accountants confirming the adequacy of the Defeasance Collateral is not
delivered, (vi) all costs to be incurred in connection with such defeasance
(including Rating Agency fees, accountants' fees and costs incurred in
connection with any required opinions of counsel) would not be paid by the
related Mortgagor, or (vii) unless such confirmation is not required pursuant to
the first paragraph of this Section 3.20(k), either Rating Agency does not
confirm in writing to the Master Servicer that the acceptance of a pledge of the
Defeasance Collateral (in lieu of a full prepayment, if applicable) will not
result in an Adverse Rating Event with respect to any Class of Certificates
rated by such Rating Agency.

          All expenses related to the defeasance of a Serviced Mortgage Loan
shall be charged to the related Mortgagor or other responsible party.


                                     -240-



          With respect to any Defeasance Serviced Trust Mortgage Loan that is a
Lehman Trust Mortgage Loan, to the extent the related Mortgage Loan documents
expressly grant the lender or its designee the right to appoint a successor
borrower (or words of similar import) thereunder in connection with a
defeasance, the Trustee hereby designates LBHI as its designee with respect to
the exercise of, and hereby grants to LBHI the right, in its capacity as
designee of the Trustee as holder of the subject Serviced Trust Mortgage Loan,
to exercise, the right and/or obligation of the lender under the related
Mortgage Loan documents to appoint a "successor borrower" (as defined under the
related Mortgage Loan documents) or words of similar import, to hold and pledge
the related Defeasance Collateral in the event a related Mortgagor exercises its
right pursuant to the related Mortgage Loan documents to defease the subject
Serviced Trust Mortgage Loan and obtain the release of all or a portion of the
related Mortgaged Property from the lien of the related Mortgage (provided that
such rights and/or obligations as successor borrower shall be exercised in
accordance with customary terms and costs). In connection with the foregoing, if
the Master Servicer or the Trustee, as holder of the subject Defeasance Serviced
Trust Mortgage Loan, receives written notice from the related Mortgagor that it
intends to defease the subject Lehman Trust Mortgage Loan in accordance with the
related Mortgage Loan documents, then the Trustee or the Master Servicer, as the
case may be, shall send a copy of such written notice to LBHI or (if LBHI has
notified the Master Servicer or the Trustee, as the case may be, in writing that
it has appointed a designee and has provided such party with such designee's
contact information for any notice required in connection therewith) LBHI's
designee, promptly after receipt of such written notice. If, however, the Master
Servicer, in accordance with the Servicing Standard, determines that neither
LBHI nor its designee is performing the duties related to the appointment of a
successor borrower in a timely manner and/or in accordance with the provisions
of the related Mortgage Loan documents (after LBHI and such designee having been
provided with written notice in accordance with this paragraph and a reasonable
period of time (which shall not be less than five (5) Business Days) to perform
such duties), then the Master Servicer (or a designee of the Master Servicer)
shall itself perform those obligations under the related Mortgage Loan documents
in accordance with the Servicing Standard, applicable law and the related
Mortgage Loan documents, and thereupon the appointment of LBHI or its designee
in connection therewith shall be null and void. In the event, with respect to a
Defeasance Serviced Trust Mortgage Loan that is a Lehman Trust Mortgage Loan,
LBHI, the Master Servicer or a designee of LBHI or the Master Servicer actually
appoints a successor borrower in accordance with the related Mortgage Loan
documents and the foregoing provisions of this paragraph and the relevant
portion or all, as applicable, of the subject Mortgaged Property is released
from the lien of the related Mortgage, then, to the extent provided under the
related Mortgage Loan documents, such successor borrower shall succeed to all of
the rights and obligations of the original Mortgagor under such Lehman Trust
Mortgage Loan. In the event LBHI, by written notice to the Trustee and the
Master Servicer, designates a third party to exercise its rights under this
paragraph and provides contact information therefor, the Trustee and the Master
Servicer shall be entitled to rely on such notice and, in such event, all
notices required to be delivered to LBHI pursuant to this paragraph shall be
delivered to LBHI's designee.

          (l) If the Master Servicer receives notice from the Mortgagor under
any Early Defeasance Trust Mortgage Loan that such Mortgagor intends to defease
such Early Defeasance Trust Mortgage Loan, in whole or in part, on or before the
second anniversary of the Closing Date, then promptly after receipt of such
notice the Master Servicer shall calculate or cause to be calculated the cash
amount required to be tendered by such Mortgagor to purchase the Defeasance
Collateral or other permitted collateral required to defease such Early
Defeasance Trust Mortgage Loan. If (i) the defeasance is to be in full and the
cash amount required to be tendered by the Mortgagor to purchase the


                                     -241-



Defeasance Collateral or other permitted collateral required to defease the
subject Early Defeasance Trust Mortgage Loan (in accordance with the related
loan documents) is less than an amount equal to the Purchase Price (calculated
as if the subject Serviced Trust Mortgage Loan was to be repurchased in
connection with a Material Breach or Material Document Defect as of the date
such defeasance is scheduled to occur), or (ii) the defeasance is to be in part,
or (iii) the defeasance is to be in full and the related Mortgagor is to tender
Defeasance Collateral or such other collateral as is permitted in connection
with a defeasance under the related loan documents that does not constitute a
cash amount equal to or greater than the Purchase Price set forth in clause (i)
above, then the Master Servicer shall promptly notify the Depositor (if such
Early Defeasance Trust Mortgage Loan is a Lehman Trust Mortgage Loan) or the UBS
Mortgage Loan Seller (if such Early Defeasance Trust Mortgage Loan is a UBS
Trust Mortgage Loan), and upon delivery by the related Mortgagor of the
Defeasance Collateral, or cash sufficient to purchase the Defeasance Collateral,
contemplated by the related loan documents, the Depositor (if such Early
Defeasance Trust Mortgage Loan is a Lehman Trust Mortgage Loan) or the UBS
Mortgage Loan Seller (if such Early Defeasance Trust Mortgage Loan is a UBS
Trust Mortgage Loan) shall be required, pursuant to or as contemplated by
Section 2.03(j) (if applicable), to repurchase such Early Defeasance Trust
Mortgage Loan on or before the proposed date on which such Early Defeasance
Trust Mortgage Loan will be defeased. The Master Servicer shall use reasonable
efforts to require the Depositor or the UBS Mortgage Loan Seller, as applicable,
to make any such required repurchase described above. If the defeasance is to be
in full and the cash amount required to be tendered by the Mortgagor to purchase
the Defeasance Collateral or other permitted collateral required to purchase the
Defeasance Collateral or other permitted collateral required to defease the
subject Early Defeasance Trust Mortgage Loan is equal to or exceeds an amount
equal to the Purchase Price set forth in clause (i) of the preceding sentence
(as calculated as of the date such purchase is to be made), then the Master
Servicer shall, notwithstanding the related loan documents, (i) treat the cash
amount tendered by such Mortgagor to defease the subject Early Defeasance Trust
Mortgage Loan as a prepayment in full of such Early Defeasance Trust Mortgage
Loan by the related Mortgagor on the related Due Date coinciding with or next
succeeding the defeasance date (and any Excess Defeasance Deposit Proceeds shall
be allocated by the Trustee among and paid to the Certificateholders in
accordance with Section 4.01, with any Excess Defeasance Deposit Proceeds to
constitute, and be treated in the same manner as a payment of any other type of,
Prepayment Consideration), (ii) deposit in the Pool Custodial Account the cash
amount tendered by such Mortgagor to purchase the Defeasance Collateral or other
permitted collateral required to defease the subject Early Defeasance Trust
Mortgage Loan, (iii) mark the Mortgage Note "cancelled" and return it to such
Mortgagor, and (iv) take such other and further action, including the release of
the Mortgage with respect to the related Mortgaged Property, consistent with the
prepayment in full of such Mortgage Loan. The Master Servicer shall promptly
notify the Depositor and/or the UBS Mortgage Loan Seller, as applicable, of the
foregoing.

          (m) With respect to any ARD Mortgage Loan after its Anticipated
Repayment Date, the Master Servicer shall be permitted, subject to obtaining the
Special Servicer's consent, to waive (such waiver to be in writing addressed to
the related Mortgagor, with a copy to the Trustee) all or any portion of the
accrued Additional Interest on such ARD Mortgage Loan if (i) such ARD Mortgage
Loan is a Performing Serviced Mortgage Loan, (ii) prior to the related maturity
date, the related Mortgagor has requested the right to prepay such ARD Mortgage
Loan in full together with all payments required under such ARD Mortgage Loan in
connection with such prepayment (except for all or a portion of such accrued
Additional Interest), and (iii) the Master Servicer has determined, in its
reasonable, good faith judgment, that the waiver of the Trust's right to receive
such accrued Additional Interest is reasonably likely to produce a greater
payment to Certificateholders (as a collective whole) on a present value basis


                                     -242-



(the relevant discounting of anticipated collections that will be distributable
to Certificateholders to be performed at the related Mortgage Rate) than a
refusal to waive the right to such Additional Interest. Neither the Master
Servicer nor the Special Servicer shall have any liability to the Trust, the
Certificateholders or any other Person so long as such determination is
exercised in accordance with the Servicing Standard.

          (n) Notwithstanding anything to the contrary in this Agreement, none
of the Special Servicer, the Master Servicer or the Trustee shall: (i) enter
into to any amendment or modification of any Co-Lender Agreement, the effect of
which would materially and adversely affect the interests of, or materially
increase or change the obligations of, any other such Person under such
Co-Lender Agreement, without first consulting with and obtaining the consent of
such other Person; or (ii) enter into any amendment or modification of any
Co-Lender Agreement unless such amendment or modification was consistent with
the Servicing Standard and satisfied the requirements for such amendments and
modifications set forth in the Co-Lender Agreement.

          (o) Notwithstanding anything to the contrary in this Agreement,
neither the Master Servicer nor the Special Servicer shall waive, modify or
reduce any amount constituting an assumption fee (or portion thereof) payable by
a Mortgagor if and to the extent such assumption fee (or applicable portion
thereof) would be payable to the other such party as additional servicing
compensation, as the case may be, without the consent of such other party. To
the extent that the Master Servicer and the Special Servicer, in accordance with
the preceding sentence, waive (or consent to a waiver of, as applicable) any
amount constituting an assumption fee (or applicable portion thereof) in respect
of any Mortgage Loan, the respective amounts of additional servicing
compensation payable to the Master Servicer and the Special Servicer from such
assumption fee (or applicable portion thereof) shall be reduced proportionately
based upon the respective amounts that would have been payable thereto as
additional servicing compensation from such assumption fee (or applicable
portion thereof) if such waiver had not been granted.

          SECTION 3.21.  Transfer of Servicing Between Master Servicer and
                         Special Servicer; Record Keeping.

          (a) Upon determining that a Servicing Transfer Event has occurred with
respect to any Serviced Mortgage Loan that had otherwise been a Performing
Serviced Mortgage Loan, and if the Master Servicer is not also the Special
Servicer, the Master Servicer shall immediately give notice thereof (or, if
applicable, the Special Servicer shall immediately give notice thereof to the
Master Servicer), and the Master Servicer shall deliver a copy of the related
Servicing File, to the Special Servicer and shall use reasonable efforts to
provide the Special Servicer with all information, documents (or copies thereof)
and records (including records stored electronically on computer tapes, magnetic
discs and the like) relating to such Mortgage Loan, either in the Master
Servicer's or any of its directors', officers', employees', affiliates' or
agents' possession or control or otherwise available to the Master Servicer
without undue burden or expense, and reasonably requested by the Special
Servicer to enable it to assume its functions hereunder with respect thereto
without acting through a Sub-Servicer. The Master Servicer shall use reasonable
efforts to comply with the preceding sentence within five (5) Business Days of
the occurrence of each related Servicing Transfer Event (or of notice of the
occurrence of such Servicing Transfer Event, if applicable); provided, however,
that if the information, documents and records requested by the Special Servicer
are not contained in the Servicing File, the Master Servicer shall have such
period of time as reasonably necessary to make such delivery. The Special


                                     -243-



Servicer may conclusively rely on the Master Servicer's determination (and the
Master Servicer may conclusively rely on the Special Servicer's determination,
as applicable) that a Servicing Transfer Event has occurred giving rise to a
Serviced Mortgage Loan's becoming a Specially Serviced Mortgage Loan. The
Special Servicer shall not be liable or in default hereunder for any reasonable
act or failure to act because of or arising out of the Master Servicer's failure
to deliver information, documents or records with respect to any Specially
Serviced Mortgage Loan in accordance with the requirements hereof.

          Upon determining that a Specially Serviced Mortgage Loan has become a
Corrected Mortgage Loan, and if the Master Servicer is not also the Special
Servicer, the Special Servicer shall immediately give notice thereof, and shall
within five (5) Business Days of such occurrence return the related Servicing
File, together with any and all new information, documents and records relating
to the subject Mortgage Loan that were not part of the Servicing File when it
was delivered to the Special Servicer, to the Master Servicer (or such other
Person as may be directed by the Master Servicer) and upon giving such notice,
and returning such Servicing File, to the Master Servicer (or such other Person
as may be directed by the Master Servicer), the Special Servicer's obligation to
service such Mortgage Loan, and the Special Servicer's right to receive the
Special Servicing Fee with respect to such Mortgage Loan shall terminate, and
the obligations of the Master Servicer to service and administer such Mortgage
Loan shall resume.

          Notwithstanding anything herein to the contrary, in connection with
the transfer to the Special Servicer of the servicing of a Cross-Collateralized
Mortgage Loan as a result of a Servicing Transfer Event or the re-assumption of
servicing responsibilities by the Master Servicer with respect to any such
Serviced Mortgage Loan upon its becoming a Corrected Mortgage Loan, the Master
Servicer and the Special Servicer shall each transfer to the other, as and when
applicable, the servicing of all other Cross-Collateralized Mortgage Loans
constituting part of the same Cross-Collateralized Group; provided that no
Cross-Collateralized Mortgage Loan may become a Corrected Mortgage Loan at
anytime that a continuing Servicing Transfer Event exists with respect to
another Cross-Collateralized Mortgage Loan in the same Cross-Collateralized
Group.

          (b) In servicing any Specially Serviced Mortgage Loans, the Special
Servicer shall provide to the Custodian originals of newly executed documents
included within the definition of "Mortgage File" for inclusion in the related
Mortgage File (with a copy of each such original to the Master Servicer), and
shall provide to the Master Servicer copies of any additional related Mortgage
Loan information, including correspondence with the related Mortgagor.

          (c) Upon request (and to the extent not otherwise already provided by
the Special Servicer pursuant to its reporting obligations hereunder), the
Special Servicer shall deliver to the Master Servicer, the Trustee and each
Rating Agency (or such other Person as may be directed by the Master Servicer) a
statement in writing and in computer readable format (the form of such statement
to be agreed upon by the Master Servicer and the Special Servicer) describing,
on a loan-by-loan and property-by-property basis, (1) insofar as it relates to
Specially Serviced Mortgage Loans and REO Properties, the information described
in clauses (viii) through (xvii) of Section 4.02(a) (with respect to information
set forth in such clauses related to prior Distribution Dates and/or periods,
the Special Servicer may conclusively rely on information furnished to it by the
Master Servicer or the Trustee) and, insofar as it relates to the Special
Servicer, the information described in clauses (xxvi), (xxxii) and (xxxiii) of
Section 4.02(a), (2) the amount of all payments, Insurance Proceeds,
Condemnation Proceeds and Liquidation Proceeds received, and the amount of any
Realized Loss incurred, with respect to each


                                     -244-



Specially Serviced Mortgage Loan during the related Collection Period, and the
amount of Insurance Proceeds, Condemnation Proceeds and Liquidation Proceeds
received, and the amount of any Realized Loss incurred, with respect to each
Administered REO Property during the related Collection Period, (3) the amount,
purpose and date of all Servicing Advances made by the Special Servicer with
respect to each Specially Serviced Mortgage Loan and Administered REO Property
during the related Collection Period, (4) in writing, a brief narrative summary
of the status of each Specially Serviced Mortgage Loan and (5) such additional
information relating to the Specially Serviced Mortgage Loans and Administered
REO Properties as the Master Servicer reasonably requests to enable it to
perform its responsibilities under this Agreement. Notwithstanding the foregoing
provisions of this subsection (c), the Master Servicer shall maintain ongoing
payment records with respect to each of the Specially Serviced Mortgage Loans
and Administered REO Properties and shall provide the Special Servicer with any
information reasonably available to the Master Servicer required by the Special
Servicer to perform its duties under this Agreement.

          SECTION 3.22.  Sub-Servicing Agreements.

          (a) Subject to Section 3.22(b) and Section 3.22(f), the Master
Servicer and the Special Servicer may enter into Sub-Servicing Agreements to
provide for the performance by third parties of any or all of their respective
obligations hereunder, provided that in each case, the Sub-Servicing Agreement:
(i) is consistent with this Agreement in all material respects, requires the
Sub-Servicer to comply with all of the applicable conditions of this Agreement
and, with the exception of Sections 7.01(a)(x) through (xiii), provides for
events of default with respect to the Sub-Servicer substantially the same as
those set forth in Section 7.01 (modified as necessary to apply to the
Sub-Servicer's obligations under the Sub-Servicing Agreement); (ii) provides
that if the Master Servicer or the Special Servicer, as the case may be, shall
for any reason no longer act in such capacity hereunder (including by reason of
an Event of Default), the Trustee or its designee may thereupon assume all of
the rights and, except to the extent they arose prior to the date of assumption,
obligations of the Master Servicer or the Special Servicer, as the case may be,
under such sub-servicing agreement or may terminate such sub-servicing agreement
without cause and without payment of any penalty or termination fee (provided,
however, that those Sub-Servicing Agreements in effect as of the Closing Date
(or, if being negotiated as of the Closing Date, in effect within 90 days
thereafter) may only be terminated by the Trustee or its designee as
contemplated by Section 3.22(d) hereof and in such additional manner as is
provided in such Sub-Servicing Agreement); (iii) provides that the Trustee, for
the benefit of the Certificateholders and, in the case of a Sub-Servicing
Agreement relating to a Serviced Loan Combination, the related Serviced
Non-Trust Mortgage Loan Noteholder(s), shall each be a third-party beneficiary
under such sub-servicing agreement, but that (except to the extent the Trustee
or its designee assumes the obligations of the Master Servicer or the Special
Servicer, as the case may be, thereunder as contemplated by the immediately
preceding clause (ii)) none of the Trustee, the Trust, any successor Master
Servicer or the Special Servicer, as the case may be, any Serviced Non-Trust
Mortgage Loan Noteholder or any Certificateholder shall have any duties under
such agreement or any liabilities arising therefrom; (iv) permits any purchaser
of a Serviced Trust Mortgage Loan pursuant to this Agreement to terminate such
sub-servicing agreement with respect to such purchased Trust Mortgage Loan at
its option and without penalty; (v) does not permit the Sub-Servicer to enter
into or consent to any modification, extension, waiver or amendment or otherwise
take any action on behalf of the Master Servicer or the Special Servicer
contemplated by Section 3.08, Section 3.09 and Section 3.20 hereof without the
consent of the Master Servicer or Special Servicer, as the case may be; (vi)
does not permit the Sub-Servicer any direct rights of indemnification that may
be satisfied out of assets of the Trust


                                     -245-



Fund; (vii) provides that, if the Sub-Servicer constitutes an Additional Item
1123 Servicer, then it will deliver to the applicable parties an Annual
Statement of Compliance in respect of the Sub-Servicer as and when contemplated
by Section 3.13; (viii) provides that, if the Sub-Servicer constitutes a
Sub-Servicing Function Participant, then it will deliver, or cause to be
delivered, to the applicable parties, an Annual Assessment Report in respect of
the Sub-Servicer and a corresponding Annual Attestation Report (together with,
if required to be filed with the Commission under applicable law, the consent of
the applicable registered public accounting firm to file such corresponding
Annual Attestation Report with the Commission) as and when contemplated by
Section 3.14; (ix) provides that the Sub-Servicer will deliver to the Master
Servicer a backup certification substantially similar to the Master Servicer
Backup Certification with respect to the Sub-Servicer, with such delivery to
occur at or before the same times, and under the same circumstances, as the
Master Servicer Backup Certification to be delivered by or with respect to the
Master Servicer (except that each such document delivered by the Sub-Servicer
shall only cover the Mortgage Loans being subserviced thereby); and (x) includes
a representation by the Sub-Servicer that such Sub-Servicer is not an
"affiliate" (as such term is defined in Section III of PTE 2000-58) of the
Trustee or of any "affiliate" (as such term is defined in Section III of PTE
2000-58) of the Trustee (provided that this clause (x) shall not apply to a
Sub-Servicer listed on Exhibit K hereto). In addition, each Sub-Servicing
Agreement entered into by the Master Servicer (including any with an effective
date on or before the Closing Date) shall provide that such agreement shall,
with respect to any Serviced Mortgage Loan serviced thereunder, terminate at the
time such Mortgage Loan becomes a Specially Serviced Mortgage Loan (or,
alternatively, be subject to the Special Servicer's rights to service such
Serviced Mortgage Loan for so long as such Mortgage Loan continues to be a
Specially Serviced Mortgage Loan), and each Sub-Servicing Agreement entered into
by the Special Servicer shall relate only to Specially Serviced Mortgage Loans
and shall terminate with respect to any such Mortgage Loan which ceases to be a
Specially Serviced Mortgage Loan. The Master Servicer and the Special Servicer
each shall deliver to the Trustee and each other copies of all Sub-Servicing
Agreements (and, to the related Serviced Non-Trust Mortgage Loan Noteholder, a
copy of any Sub-Servicing Agreement in respect of a Serviced Non-Trust Mortgage
Loan), as well as any amendments thereto and modifications thereof, entered into
by it promptly upon its execution and delivery of such documents. References in
this Agreement to actions taken or to be taken by the Master Servicer or the
Special Servicer include actions taken or to be taken by a Sub-Servicer on
behalf of the Master Servicer or the Special Servicer, as the case may be; and,
in connection therewith, all amounts advanced by any Sub-Servicer to satisfy the
obligations of the Master Servicer or the Special Servicer hereunder to make P&I
Advances or Servicing Advances shall be deemed to have been advanced by the
Master Servicer or the Special Servicer, as the case may be, out of its own
funds and, accordingly, such P&I Advances or Servicing Advances shall be
recoverable by such Sub-Servicer in the same manner and out of the same funds as
if such Sub-Servicer were the Master Servicer or the Special Servicer, as the
case may be. For so long as they are outstanding, Advances shall accrue interest
in accordance with Sections 3.11(g) or 4.03(d), as applicable, such interest to
be allocable between the Master Servicer or the Special Servicer, as the case
may be, and such Sub-Servicer as they may agree. For purposes of this Agreement,
the Master Servicer and the Special Servicer each shall be deemed to have
received any payment when a Sub-Servicer retained by it receives such payment.
The Master Servicer and the Special Servicer each shall notify the other, the
Trustee, the Depositor, the Controlling Class Certificateholders and, if a
Serviced Loan Combination is involved, the related Non-Trust Mortgage Loan
Noteholder(s) in writing promptly of the appointment by it of any Sub-Servicer.
The Master Servicer and the Special Servicer shall each notify the Trustee and
the Depositor in writing, promptly upon becoming aware thereof, whether any
Sub-Servicer retained by it constitutes an Additional Item 1123 Servicer or a
Sub-Servicing Function Participant. The initial Special Servicer hereby
represents and warrants that, as of the Closing Date, it


                                     -246-



has not retained and does not expect to retain any particular Person or group of
affiliated Persons to act as a Sub-Servicer with respect to 10% or more of the
Mortgage Pool (by balance). The initial Master Servicer hereby represents and
warrants that the only Persons with which it has entered into or is negotiating
a Sub-Servicing Agreement as of the Closing Date are listed on Exhibit K and, in
each such case, the Sub-Servicing Agreement shall not cover any Mortgage Loan
(other than the Mortgage Loans identified on Exhibit K hereto with respect to
such Sub-Servicer) that the subject Sub-Servicer did not primary service prior
to the Closing Date.

          (b) Each Sub-Servicer (i) shall be authorized to transact business in
the state or states in which the related Mortgaged Properties it is to service
are situated, if and to the extent required by applicable law, and (ii) except
for any Sub-Servicer that is servicing any of the Serviced Mortgage Loans on the
Closing Date, shall be an approved conventional seller/servicer of mortgage
loans for FHLMC or Fannie Mae or a HUD-Approved Servicer.

          (c) The Master Servicer and the Special Servicer, for the benefit of
the Trustee and the Certificateholders and, in the case of a Serviced Loan
Combination, also for the benefit of the related Serviced Non-Trust Mortgage
Loan Noteholder(s), shall (at no expense to the Trustee, any Certificateholder,
any Serviced Non-Trust Mortgage Loan Noteholder or the Trust Fund) monitor the
performance and enforce the obligations of their respective Sub-Servicers under
the related Sub-Servicing Agreements. Such enforcement, including the legal
prosecution of claims, termination of Sub-Servicing Agreements in accordance
with their respective terms and the pursuit of other appropriate remedies, shall
be in such form and carried out to such an extent and at such time as the Master
Servicer or the Special Servicer, as applicable, in its good faith business
judgment, would require were it the owner of the subject Serviced Mortgage
Loans.

          (d) In the event of the resignation, removal or other termination of
the Master Servicer or any successor Master Servicer hereunder for any reason,
the Trustee or other Person succeeding such resigning, removed or terminated
party as Master Servicer, shall elect, with respect to any Sub-Servicing
Agreement in effect as of the Closing Date (or, if being negotiated as of the
Closing Date, in effect within 90 days thereafter) that still exists at the time
of such termination: (i) to assume the rights and obligations of the Master
Servicer under such Sub-Servicing Agreement and continue the sub-servicing
arrangements thereunder on the same terms (including the obligation to pay the
same sub-servicing fee); (ii) to enter into a new Sub-Servicing Agreement with
such Sub-Servicer on such terms as the Trustee or other successor Master
Servicer and such Sub-Servicer shall mutually agree (it being understood that
such Sub-Servicer is under no obligation to accept any such new Sub-Servicing
Agreement or to enter into or continue negotiations with the Trustee or other
successor Master Servicer), provided that neither the Trustee nor any successor
Master Servicer shall enter into a new Sub-Servicing Agreement with a
Sub-Servicer that was a party to a Sub-Servicing Agreement as of the Closing
Date, if such new Sub-Servicing Agreement amends, alters or fails to restate any
rights of any Underwriter or Mortgage Loan Seller under the existing
Sub-Servicing Agreement with respect to the termination of the Sub-Servicer and
the appointment of a successor thereto or any rights of any Underwriter or
Mortgage Loan Seller as a third-party beneficiary under such Sub-Servicing
Agreement, unless the successor Master Servicer has obtained the prior written
consent to the terms of such new Sub-Servicing Agreement from such Underwriter
or Mortgage Loan Seller, as the case may be; or (iii) to terminate the
Sub-Servicing Agreement if (but only if) an Event of Default (as defined in such
Sub-Servicing Agreement) has occurred and is continuing, without paying any
sub-servicer termination fee, and in any additional manner provided for in such
Sub-Servicing Agreement.


                                     -247-



          (e) Notwithstanding any Sub-Servicing Agreement or the use of any
Servicing Representative, the Master Servicer and the Special Servicer shall
remain obligated and liable to the Trustee, the Certificateholders and the
Serviced Non-Trust Mortgage Loan Noteholder(s) for the performance of their
respective obligations and duties under this Agreement in accordance with the
provisions hereof to the same extent and under the same terms and conditions as
if each alone were servicing and administering the Serviced Mortgage Loans
and/or Administered REO Properties for which it is responsible. The Master
Servicer and the Special Servicer shall each be responsible (without right of
reimbursement) for all compensation of each Sub-Servicer or other Servicing
Representative retained by it.

          (f) Notwithstanding the above, the Special Servicer may not enter into
any Sub-Servicing Agreement without the approval of the Controlling Class
Representative. In addition, notwithstanding anything herein to the contrary,
until the Trustee files a Form 15 with respect to the Trust in accordance with
Section 8.15, the Special Servicer shall not retain or engage any Sub-Servicer
or other Servicing Representative without the approval of the Depositor, which
approval may not be unreasonably withheld. Furthermore, notwithstanding anything
herein to the contrary, until the Trustee files a Form 15 with respect to the
Trust in accordance with Section 8.15, the Master Servicer shall not retain or
engage any Sub-Servicer or any other Servicing Representative without the
approval of the Depositor, but (in the case of the initial Master Servicer) only
if and to the extent that such approval is required under the Master Servicer
Indemnification Agreement. The agreements set forth in this Section 3.22(f) are
in addition to any other agreements (including any applicable indemnity
arrangements) that the parties hereto may have with respect to the subject
matter of this Section 3.22(f).

          SECTION 3.23.  Representations and Warranties of the Master Servicer.

          (a) The Master Servicer, in such capacity, hereby represents, warrants
and covenants to the other parties hereto and for the benefit of the
Certificateholders and the Serviced Non-Trust Mortgage Loan Noteholders, as of
the Closing Date, that:

               (i) The Master Servicer is a national banking association, duly
     organized under the laws of the United States of America, and the Master
     Servicer is in compliance with the laws of each state in which any
     Mortgaged Property is located to the extent necessary to perform its
     obligations under this Agreement.

               (ii) The execution and delivery of this Agreement by the Master
     Servicer, and the performance and compliance with the terms of this
     Agreement by the Master Servicer, will not: (A) violate the Master
     Servicer's organizational documents; or (B) constitute a default (or an
     event which, with notice or lapse of time, or both, would constitute a
     default) under, or result in the breach of, any material agreement or other
     material instrument to which it is a party or which is applicable to it or
     any of its assets, which default or breach, in the good faith and
     reasonable judgment of the Master Servicer, would reasonably be expected to
     affect materially and adversely either the ability of the Master Servicer
     to perform its obligations under this Agreement or the financial condition
     of the Master Servicer.

               (iii) The Master Servicer has the full power and authority to
     enter into and consummate all transactions contemplated by this Agreement,
     has duly authorized the execution, delivery and performance of this
     Agreement, and has duly executed and delivered this Agreement.


                                     -248-



               (iv) This Agreement, assuming due authorization, execution and
     delivery by each of the other parties hereto, constitutes a valid, legal
     and binding obligation of the Master Servicer, enforceable against the
     Master Servicer in accordance with the terms hereof, subject to (A)
     applicable bankruptcy, receivership, insolvency, reorganization, moratorium
     and other laws affecting the enforcement of creditors' (including bank
     creditors') rights generally, and (B) general principles of equity,
     regardless of whether such enforcement is considered in a proceeding in
     equity or at law.

               (v) The Master Servicer is not in violation of, and its execution
     and delivery of this Agreement and its performance and compliance with the
     terms of this Agreement will not constitute a violation of, any law, any
     order or decree of any court or arbiter, or any order, regulation or demand
     of any federal, state or local governmental or regulatory authority, which
     violation, in the Master Servicer's good faith and reasonable judgment, is
     likely to affect materially and adversely either the ability of the Master
     Servicer to perform its obligations under this Agreement or the financial
     condition of the Master Servicer.

               (vi) No litigation is pending or, to the best of the Master
     Servicer's knowledge, threatened, against the Master Servicer, the outcome
     of which, in the Master Servicer's good faith and reasonable judgment,
     could reasonably be expected to prohibit the Master Servicer from entering
     into this Agreement or materially and adversely affect the ability of the
     Master Servicer to perform its obligations under this Agreement.

               (vii) Any consent, approval, authorization or order of any court
     or governmental agency or body required under federal or state law for the
     execution, delivery and performance by the Master Servicer of or compliance
     by the Master Servicer with this Agreement or the consummation of the
     transactions contemplated by this Agreement has been obtained and is
     effective except where the lack of consent, approval, authorization or
     order would not have a material adverse effect on the performance by the
     Master Servicer under this Agreement.

               (viii) The Master Servicer possesses all insurance required
     pursuant to Section 3.07(c) of this Agreement.

               (ix) The Master Servicer has reviewed all Sub-Servicing
     Agreements in effect as of the Closing Date and will review all
     Sub-Servicing Agreements entered into by it after the Closing Date.

          (b) The representations and warranties of the Master Servicer set
forth in Section 3.23(a) shall survive the execution and delivery of this
Agreement and shall inure to the benefit of the Persons for whose benefit they
were made for so long as the Trust Fund remains in existence. Upon discovery by
any party hereto of any breach of any of the foregoing representations and
warranties, the party discovering such breach shall give prompt written notice
thereof to the other parties hereto.

          (c) Any successor Master Servicer shall be deemed to have made, as of
the date of its succession, each of the representations and warranties set forth
in Section 3.23(a), subject to such appropriate modifications to the
representation and warranty set forth in Section 3.23(a)(i) to accurately
reflect such successor's jurisdiction of organization and whether it is a
corporation, partnership, bank, association or other type of organization.


                                     -249-



          SECTION 3.24.  Representations and Warranties of the Special Servicer.

          (a) The Special Servicer, in such capacity, hereby represents,
warrants and covenants to the other parties hereto and for the benefit of the
Certificateholders and the Serviced Non-Trust Mortgage Loan Noteholders, as of
the Closing Date, that:

               (i) The Special Servicer is a corporation validly existing and in
     good standing under the laws of the State of Florida, and the Special
     Servicer is in compliance with the laws of each state in which any
     Mortgaged Property is located to the extent necessary to perform its
     obligations under this Agreement.

               (ii) The execution and delivery of this Agreement by the Special
     Servicer, and the performance and compliance with the terms of this
     Agreement by the Special Servicer, will not: (A) violate the Special
     Servicer's organizational documents; or (B) constitute a default (or an
     event which, with notice or lapse of time, or both, would constitute a
     default) under, or result in the breach of, any material agreement or other
     material instrument to which it is a party or which is applicable to it or
     any of its assets, which default or breach, in the good faith and
     reasonable judgment of the Special Servicer, would reasonably be expected
     to affect materially and adversely either the ability of the Special
     Servicer to perform its obligations under this Agreement or the financial
     condition of the Special Servicer.

               (iii) The Special Servicer has the full power and authority to
     enter into and consummate all transactions contemplated by this Agreement,
     has duly authorized the execution, delivery and performance of this
     Agreement, and has duly executed and delivered this Agreement.

               (iv) This Agreement, assuming due authorization, execution and

     Special Servicer in accordance with the terms hereof, subject to (A)
     applicable bankruptcy, insolvency, reorganization, moratorium and other
     laws affecting the enforcement of creditors' rights generally, and (B)
     general principles of equity, regardless of whether such enforcement is
     considered in a proceeding in equity or at law.

               (v) The Special Servicer is not in violation of, and its
     execution and delivery of this Agreement and its performance and compliance
     with the terms of this Agreement will not constitute a violation of, any
     law, any order or decree of any court or arbiter, or any order, regulation
     or demand of any federal, state or local governmental or regulatory
     authority, which violation, in the Special Servicer's good faith and
     reasonable judgment, is likely to affect materially and adversely either
     the ability of the Special Servicer to perform its obligations under this
     Agreement or the financial condition of the Special Servicer.

               (vi) No litigation is pending or, to the best of the Special
     Servicer's knowledge, threatened, against the Special Servicer, the outcome
     of which, in the Special Servicer's good faith and reasonable judgment,
     could reasonably be expected to prohibit the Special Servicer from entering
     into this Agreement or materially and adversely affect the ability of the
     Special Servicer to perform its obligations under this Agreement.


                                     -250-



               (vii) Any consent, approval, authorization or order of any court
     or governmental agency or body required under federal or state law for the
     execution, delivery and performance by the Special Servicer of or
     compliance by the Special Servicer with this Agreement or the consummation
     of the transactions contemplated by this Agreement has been obtained and is
     effective except where the lack of consent, approval, authorization or
     order would not have a material adverse effect on the performance by the
     Special Servicer under this Agreement.

               (viii) The Special Servicer possesses all insurance required
     pursuant to Section 3.07(c) of this Agreement.

          (b) The representations and warranties of the Special Servicer set
forth in Section 3.24(a) shall survive the execution and delivery of this
Agreement and shall inure to the benefit of the Persons for whose benefit they
were made for so long as the Trust Fund remains in existence. Upon discovery by
any party hereto of any breach of any of the foregoing representations and
warranties, the party discovering such breach shall give prompt written notice
thereof to the other parties hereto.

          (c) Any successor Special Servicer shall be deemed to have made, as of

          SECTION 3.25.  Certain Matters Regarding the Purchase of the Trust
                         Mortgage Loan in a Loan Combination.

          If, in connection with a Permitted Purchase, a Trust Mortgage Loan
that is part of a Loan Combination is purchased or repurchased from the Trust
Fund, the purchaser(s) thereof shall be bound by the terms of the related
Co-Lender Agreement and shall assume the rights and obligations of the holder of
such Mortgage Loan under such Co-Lender Agreement. Subject to the terms of the
related Co-Lender Agreement, all portions of the related Mortgage File and other
documents pertaining to the subject Trust Mortgage Loan shall be endorsed or
assigned, to the extent necessary or appropriate, to the purchaser(s) of such
Trust Mortgage Loan in their capacity as holder of such Trust Mortgage Loan (as
a result of such purchase or repurchase) under the related Co-Lender Agreement
in the manner contemplated thereunder, which such purchaser(s) shall be deemed
to acknowledge. Thereafter, in the case of a Serviced Combination Trust Mortgage
Loan, such Mortgage File shall be held by the lender responsible for maintaining
custody thereof under the related Co-Lender Agreement, or a custodian appointed
thereby, for the benefit of each of the "Lenders" as defined under, and as their
interests appear under, the related Co-Lender Agreement; provided that the
Mortgage Note for such Serviced Combination Trust Mortgage Loan may be held by
the purchaser(s) of such Mortgage Loan. If the related Servicing File is not
already in the possession of such party, it shall be delivered to the successor
master servicer or special servicer, as the case may be, with respect to the
subject Loan Combination under, or otherwise in accordance with, any applicable
separate servicing agreement for such Loan Combination or as otherwise
contemplated by the related Co-Lender Agreement.

          SECTION 3.26.  Application of Default Charges.

          (a) Any and all Default Charges that are actually Received by the
Trust and deposited in the Pool Custodial Account with respect to any Trust
Mortgage Loan or REO Trust Mortgage Loan during any applicable Collection
Period, shall be applied for the following purposes and in the following order,
in each case to the extent of the remaining portion of such Default Charges:

               first, to pay to any Fiscal Agent, the Trustee, the Master
     Servicer and the Special Servicer, in that order, any interest due and
     owing to such party on any outstanding Advances made thereby with respect
     to such Trust Mortgage Loan or REO Trust Mortgage Loan, as the case may be,
     which interest on such outstanding Advance accrued on or prior to the date
     on which the subject Default Charges were received;

               second, to pay any other outstanding expenses (exclusive of
     Special Servicing Fees, Liquidation Fees and Workout Fees) incurred with
     respect to such Trust Mortgage Loan or REO Trust Mortgage Loan, as the case
     may be, that, if paid from collections on the Mortgage Pool other than such
     Default Charges, would constitute an Additional Trust Fund Expense;

               third, to reimburse the Trust for any interest on Advances paid
     to any Fiscal Agent, the Trustee, the Master Servicer or the Special
     Servicer since the Closing Date with respect to such Trust Mortgage Loan or
     REO Trust Mortgage Loan, as the case may be, which interest payment was
     made from collections on the Mortgage Pool (other than Default Charges on
     such Trust Mortgage Loan or REO Trust Mortgage Loan) and was not previously
     reimbursed under this clause third;

               fourth, to reimburse the Trust for any other Additional Trust
     Fund Expenses (exclusive of Special Servicing Fees, Liquidation Fees and
     Workout Fees) paid since the Closing Date with respect to such Trust
     Mortgage Loan or REO Trust Mortgage Loan, as the case may be, which payment
     was made from collections on the Mortgage Pool (other than Default Charges
     on such Trust Mortgage Loan or REO Trust Mortgage Loan) and was not
     previously reimbursed under this clause fourth; and

               fifth, to pay any remaining portion of such Default Charges (such
     remaining portion, "Net Default Charges") as additional master servicing
     compensation to the Master Servicer, if they were accrued in respect of an
     Outside Serviced Trust Mortgage Loan or a Performing Serviced Trust
     Mortgage Loan, or as additional special servicing compensation to the
     Special Servicer, if they were accrued in respect of a Specially Serviced
     Trust Mortgage Loan or an REO Trust Mortgage Loan, in each case pursuant to
     Section 3.11;

provided that any and all Default Charges that are actually collected with
respect to a Serviced Combination Trust Mortgage Loan shall first be applied
pursuant to the applicable section of this Agreement related to permitted
withdrawals from the related Loan Combination Custodial Account (Section 3.05A)
and the applicable provisions of the related Co-Lender Agreement; and provided,
further, that the total interest on Advances payable pursuant to clause first
above and other expenses payable pursuant to clause second above in connection
with a Serviced Combination Trust Mortgage Loan or any successor REO Trust
Mortgage Loan with respect thereto shall take into account the application of
funds on deposit in the related Loan Combination Custodial Account with respect
to the related Serviced Non-Trust Mortgage Loan(s) or any successor REO Mortgage
Loan(s) with respect


                                     -252-



thereto to pay such interest on Advances or such other expenses, as the case may
be; and provided, further, that, with respect to a Serviced Loan Combination,
Default Charges that are actually Received by the Trust with respect to any
Serviced Combination Trust Mortgage Loan or REO Trust Mortgage Loan with respect
thereto during any applicable Collection Period shall be applied to cover the
items set forth in clauses first through fourth above only to the extent that
such item or portion of such item (i) is allocable to such Serviced Combination
Trust Mortgage Loan or any successor REO Trust Mortgage Loan with respect
thereto in accordance with the related Co-Lender Agreement and (ii) is not
otherwise first payable, pursuant to Section 3.26(c) or Section 3.26(d) (and
consistent with the related Co-Lender Agreement), out of amounts otherwise
distributable to a related Serviced Non-Trust Mortgage Loan Noteholder as
Default Charges with respect to a related Serviced Non-Trust Mortgage Loan or
any successor REO Mortgage Loan with respect thereto or, pursuant to Section
3.05A (and consistent with the related Co-Lender Agreement) out of any other
amounts otherwise distributable to a related Serviced Non-Trust Mortgage Loan
Noteholder with respect to a related Serviced Non-Trust Mortgage Loan or any
successor REO Mortgage Loan with respect thereto.

          (b) Default Charges applied to reimburse the Trust pursuant to clauses
third and fourth of subsection (a), are intended to be part of the amounts to be
delivered by the Master Servicer to the Trustee pursuant to the first paragraph
of Section 3.04(b) on or before the Trust Master Servicer Remittance Date next
following the applicable Collection Period during which they were received, for
deposit in the Collection Account, subject to application pursuant to Section
3.05(a) for any items payable out of general collections on the Mortgage Pool.
Default Charges applied to pay outstanding interest on Advances in respect of
the related Trust Mortgage Loan or REO Trust Mortgage Loan, as applicable, to
any particular party, pursuant to clause first of subsection (a), shall be
applied to pay such party such interest on Advances in such manner that the
interest that accrued first and has been outstanding the longest shall be paid
first. Default Charges applied to pay outstanding expenses in respect of the
related Trust Mortgage Loan or REO Trust Mortgage Loan, as applicable, pursuant
to clause second of subsection (a), shall be applied to pay such expenses in the
chronological order in which they were incurred. Default Charges applied to
reimburse the Trust pursuant to clauses third and fourth of subsection (a) shall
be deemed to offset either interest paid on Advances or other Additional Trust
Fund Expenses, depending on which clause is applicable, in respect of the
related Trust Mortgage Loan or REO Trust Mortgage Loan, as applicable, in the
chronological order in which such interest accrued or such expenses were
incurred, as applicable (whereupon such interest paid on Advances or such other
Additional Trust Fund Expenses, depending on which clause is applicable, shall
thereafter be deemed to have been paid out of Default Charges in respect of the
related Trust Mortgage Loan or REO Trust Mortgage Loan, as applicable).

          (c) Any and all amounts otherwise distributable to a related Serviced
Non-Trust Mortgage Loan Noteholder as Default Charges with respect to any
Serviced Subordinate Non-Trust Mortgage Loan or any successor REO Mortgage Loan
with respect thereto that is part of a Serviced A/B Loan Combination, in
accordance with the related Co-Lender Agreement, shall be applied for the
following purposes and in the following order, in each case to the extent of the
remaining portion of such amounts and as and to the extent permitted under the
related Co-Lender Agreement, prior to being so distributed to the related
Serviced Non-Trust Mortgage Loan Noteholder:

               first, to pay to any Fiscal Agent, the Trustee, the Master
     Servicer and the Special Servicer, in that order, any and all interest on
     any Servicing Advances made thereby with respect to the applicable Serviced
     Loan Combination or any related REO Property, which interest


                                     -253-



     accrued on or prior to the date on which such amounts otherwise so
     distributable as Default Charges were received (such amounts to be applied
     in accordance with this clause first with respect to any such particular
     party in such manner that the earliest accrued interest shall be paid
     first);

               second, to pay to any Fiscal Agent, to the Trustee and to the
     Master Servicer, in that order, any and all interest on any P&I Advances
     made thereby with respect to the related Serviced Combination Trust
     Mortgage Loan or any successor REO Trust Mortgage Loan with respect
     thereto, which interest accrued on or prior to the date on which such
     amounts otherwise so distributable as Default Charges were received (such
     amounts to be applied with respect to any such particular party in such
     manner that the earliest accrued interest shall be paid first); and

               third, to pay any other expenses reimbursable to any party to
     this Agreement from Default Charges pursuant to the related Co-Lender
     Agreement, out of amounts otherwise distributable to the related Serviced
     Non-Trust Mortgage Loan Noteholder as Default Charges with respect to the
     subject Serviced Subordinate Non-Trust Mortgage Loan or any successor REO
     Mortgage Loan with respect thereto.

          (d) Any and all amounts otherwise distributable with respect to any
Serviced Subordinate Non-Trust Mortgage Loan (or any successor REO Mortgage Loan
with respect thereto) that is part of a Serviced Pari Passu Loan Combination (if
any) as Default Charges on any related Loan Combination Master Servicer
Remittance Date, in accordance with the related Co-Lender Agreement, shall be
applied for the following purposes and in the following order, in each case to
the extent of the remaining portion of such amounts and to the extent permitted
under the related Co-Lender Agreement, prior to application in accordance with
Section 3.26(a):

               first, to pay to any Fiscal Agent, the Trustee, the Master
     Servicer and the Special Servicer, in that order, any and all interest on
     any Servicing Advances made thereby with respect to the related Serviced
     Pari Passu Loan Combination or any related REO Property, which interest
     accrued on or prior to the date on which such amounts otherwise so
     distributable as Default Charges were received (such amounts to be applied
     in accordance with this clause first with respect to any such particular
     party in such manner that the earliest accrued interest shall be paid
     first);

               second, to pay to any Fiscal Agent, to the Trustee and to the
     Master Servicer, in that order, any and all interest on any P&I Advances
     made thereby with respect to the related Serviced Combination Trust
     Mortgage Loan (or any successor REO Trust Mortgage Loan with respect
     thereto), and, if the related Serviced Pari Passu Non-Trust Mortgage Loan
     has been securitized, to pay any party to any related Non-Trust Mortgage
     Loan Securitization Agreement any and all interest on delinquency advances
     similar to P&I Advances with respect to the related Serviced Pari Passu
     Non-Trust Mortgage Loan (or any successor REO Mortgage Loan with respect
     thereto), which interest accrued, in each case, on or prior to the date on
     which such amounts otherwise so distributable as Default Charges were
     received (such amounts to be applied with respect to any such particular
     party in such manner that the earliest accrued interest shall be paid
     first); and

               third, to pay that portion of any other expenses reimbursable to
     any party to this Agreement from Default Charges pursuant to the related
     Co-Lender Agreement, out of amounts


                                     -254-



     otherwise distributable as Default Charges with respect to the related
     Serviced Subordinate Non-Trust Mortgage Loan (or any successor REO Mortgage
     Loan with respect thereto).

          Any and all amounts otherwise distributable to the holder of the
Mortgage Note for any related Serviced Pari Passu Non-Trust Mortgage Loan as
Default Charges with respect to the related Serviced Pari Passu Non-Trust
Mortgage Loan (or any successor REO Mortgage Loan with respect thereto) on any
Loan Combination Master Servicer Remittance Date, in accordance with the related
Co-Lender Agreement, shall be applied for the following purposes and in the
following order, in each case to the extent of the remaining portion of such
amounts and to the extent permitted under the related Co-Lender Agreement, prior
to being so distributed to the related Serviced Pari Passu Non-Trust Mortgage
Loan Noteholder:

               first, to pay to any Fiscal Agent, the Trustee, the Master
     Servicer and the Special Servicer, in that order, subject to the next
     paragraph (if applicable), that portion of any and all interest on any
     Servicing Advances made thereby with respect to the related Serviced Pari
     Passu Loan Combination and/or any related REO Property, which interest
     accrued on or prior to the date on which such amounts so distributable as
     Default Charges were received, and which interest is allocable to the
     related Serviced Pari Passu Non-Trust Mortgage Loan (or any successor REO
     Mortgage Loan with respect thereto) in accordance with the related
     Co-Lender Agreement; and

               second, to pay that portion of any other expenses reimbursable to
     any party to this Agreement from Default Charges pursuant to the related
     Co-Lender Agreement (which portion of such other expenses is allocable to
     the related Serviced Pari Passu Non-Trust Mortgage Loan (or any successor
     REO Mortgage Loan with respect thereto) in accordance with the related
     Co-Lender Agreement), out of amounts otherwise distributable to the related
     Serviced Pari Passu Non-Trust Mortgage Loan Noteholder as Default Charges
     with respect to the related Serviced Pari Passu Non-Trust Mortgage Loan (or
     any successor REO Mortgage Loan with respect thereto);

provided that any application of amounts otherwise payable as Default Charges in
accordance with this paragraph shall be made after the application of amounts
otherwise payable as Default Charges with respect to any related Serviced
Subordinate Non-Trust Mortgage Loan (or any successor REO Mortgage Loan with
respect thereto) as provided above in this Section 3.26(d).

          In the case of a Serviced Pari Passu Loan Combination, any and all
amounts otherwise distributable with respect to the related Serviced Combination
Trust Mortgage Loan and the related Serviced Pari Passu Non-Trust Mortgage Loan
(or any successor REO Mortgage Loans with respect to such Mortgage Loans) as
Default Charges on any related Loan Combination Master Servicer Remittance Date,
in accordance with the related Co-Lender Agreement, shall be allocated between
them, on a pro rata and pari passu basis. If the total amount otherwise
distributable on any subject Loan Combination Master Servicer Remittance Date,
in accordance with the related Co-Lender Agreement, as Default Charges with
respect to the related Serviced Combination Trust Mortgage Loan and the related
Serviced Pari Passu Non-Trust Mortgage Loan (or any successor REO Mortgage Loans
with respect to such Mortgage Loans) exceeds the aggregate amount of (i)
interest on related Servicing Advances payable pursuant to Section 3.26(a) and
the prior two paragraphs of this Section 3.26(d) and (ii) other amounts
reimbursable from Default Charges pursuant to the related Co-Lender Agreement in
accordance with


                                     -255-



Section 3.26(a) and the prior two paragraphs of this Section 3.26(d), then the
respective portions of such total amount allocable to the related Serviced
Combination Trust Mortgage Loan and the related Serviced Pari Passu Non-Trust
Mortgage Loan (or any successor REO Mortgage Loans with respect to such Mortgage
Loans) that are to be applied for such purpose shall be in the same proportions
that the respective unpaid principal balances of the related Serviced
Combination Trust Mortgage Loan and the related Serviced Pari Passu Non-Trust
Mortgage Loan (or any successor REO Mortgage Loans with respect to such Mortgage
Loans) bear to one another.

          SECTION 3.27.  Purchase Option and Cure Rights of the Loan-Specific
                         Class Representatives.

          (a) At any time during the continuance of a Class HAF Purchase Option
Event with respect to any HAF Split Trust Mortgage Loan, the Class HAF
Representative may, at its option, purchase such HAF Split Trust Mortgage Loan
at the applicable Class HAF Purchase Price. Such option does not extend to any
REO Property and, with respect to any HAF Split Trust Mortgage Loan, shall
terminate upon the foreclosure of or the acceptance of a deed in lieu of
foreclosure with respect to the related Mortgaged Property. The Class HAF
Representative shall exercise its purchase option by providing written notice to
the Trustee, the Master Servicer and the Special Servicer of its proposed
purchase of any HAF Split Trust Mortgage Loan as to which a Class HAF Purchase
Option Event exists at least 10 days prior to the proposed purchase date (which
notice shall not be rescinded by the Class HAF Representative any later than two
Business Days prior to the proposed purchase date). Concurrently with the
payment to the Trust of the applicable Class HAF Purchase Price, the Special
Servicer shall direct the Trustee to execute and deliver, or cause the execution
and delivery of, such instruments of transfer or assignment, in each case
without recourse, as shall be provided to it by the Class HAF Representative or
its designee and as are necessary to vest ownership therein of the purchased HAF
Split Trust Mortgage Loan.

          (b) In the event that (i) a monetary event of default exists with
respect to any HAF Split Trust Mortgage Loan by the end of the applicable grace
period for the subject payment permitted under the related loan documents or
(ii) a material non-monetary event of default exists with respect to any HAF
Split Trust Mortgage Loan and is not cured within the applicable grace period
set forth under the related loan documents, then the Class HAF Representative
shall have the right, but not the obligation, to cure such default within five
days, in the case of a default in the making of a Monthly Payment, 10 Business
Days, in the case of any other monetary event of default, or 30 days, in the
case of a non-monetary event of default, after receipt of notice of the event of
default, and at no other times. If the Class HAF Representative makes such a
cure of a monetary event of default, such cure shall be made for the entire
subject HAF Split Trust Mortgage Loan. At the time such cure payment is made,
the Class HAF Representative is required to pay or reimburse the Master
Servicer, the Special Servicer, the Trustee and any Fiscal Agent, as applicable,
for all costs, expenses, losses, liabilities, obligations, damages, penalties,
and disbursements imposed on or incurred by such Persons (including, without
limitation, any interest accrued on any P&I Advances or Servicing Advances)
during the period of time from the expiration of the related grace period until
such cure payment is made. So long as a monetary event of default exists for
which a cure payment permitted under this Section 3.27(b) is made, or a material
non-monetary event of default exists which is susceptible of cure by the payment
of money and for which the Class HAF Representative is pursuing a cure within
the cure period and in accordance with the terms of this Section 3.27(b), such
event of default shall not be treated as an event of default under the related
loan documents by the Master Servicer or Special Servicer. The right of the
Class


                                     -256-



HAF Representative to cure a monetary event of default or non-monetary event of
default with respect to any HAF Split Trust Mortgage Loan shall be limited as
follows: (A) there shall not be more than eight cure events during the term of
such HAF Split Trust Mortgage Loan and (B) no more than three consecutive cures
of delinquent Monthly Payments are permitted. Each of the Master Servicer and
the Special Servicer shall notify the Class HAF Representative of any default in
respect of a HAF Split Trust Mortgage Loan with respect to which the Class HAF
Representative is entitled to exercise cure rights in accordance with this
Section 3.27(b), as soon as reasonably practicable after the Master Servicer or
the Special Servicer, as the case may be, becomes aware of such default
(provided that such default has not been previously remedied). The Class HAF
Representative shall be entitled to reimbursement of any cure payments made by
it with respect to a HAF Split Trust Mortgage Loan out of amounts subsequently
received with respect to such HAF Split Trust Mortgage Loan or any related REO
Property; provided that such right to reimbursement is subordinate to the rights
of the Trust to receive all amounts to which it is entitled with respect to such
HAF Split Trust Mortgage Loan or any successor REO Trust Mortgage Loan with
respect thereto.

          (c) At any time during the continuance of a Class SBC Purchase Option
Event with respect to the Sturbridge Commons Trust Mortgage Loan, the Class SBC
Representative may, at its option, purchase the Sturbridge Commons Trust
Mortgage Loan at the applicable Class SBC Purchase Price. Such option does not
extend to any REO Property and shall terminate upon the foreclosure of or the
acceptance of a deed in lieu of foreclosure with respect to the Sturbridge
Commons Mortgaged Property. The Class SBC Representative shall exercise its
purchase option by providing written notice to the Trustee, the Master Servicer
and the Special Servicer of its proposed purchase of the Sturbridge Commons
Trust Mortgage Loan during the existence of a Class SBC Purchase Option Event,
at least 10 days prior to the proposed purchase date (which notice shall not be
rescinded by the Class SBC Representative any later than two Business Days prior
to the proposed purchase date). Concurrently with the payment to the Trust of
the applicable Class SBC Purchase Price, the Special Servicer shall direct the
Trustee to execute and deliver, or cause the execution and delivery of, such
instruments of transfer or assignment, in each case without recourse, as shall
be provided to it by the Class SBC Representative or its designee and as are
necessary to vest ownership of the Sturbridge Commons Trust Mortgage Loan.

          (d) In the event that (i) a monetary event of default exists with
respect to the Sturbridge Commons Trust Mortgage Loan by the end of the
applicable grace period for the subject payment permitted under the related loan
documents or (ii) a material non-monetary event of default exists with respect
to the Sturbridge Commons Trust Mortgage Loan and is not cured within the
applicable grace period set forth under the related loan documents, then the
Class SBC Representative shall have the right, but not the obligation, to cure
such default within five days, in the case of a default in the making of a
Monthly Payment, 10 Business Days, in the case of any other monetary event of
default, or 30 days, in the case of a non-monetary event of default, after
receipt of notice of the event of default, and at no other times. If the Class
SBC Representative makes such a cure of a monetary event of default, such cure
shall be made for the entire Sturbridge Commons Trust Mortgage Loan. At the time
such cure payment is made, the Class SBC Representative is required to pay or
reimburse the Master Servicer, the Special Servicer, the Trustee and any Fiscal
Agent, as applicable, for all costs, expenses, losses, liabilities, obligations,
damages, penalties, and disbursements imposed on or incurred by such Persons
(including, without limitation, any interest accrued on any P&I Advances or
Servicing Advances) during the period of time from the expiration of the related
grace period until such cure payment is made. So long as a monetary event of
default exists for which a cure payment permitted


                                     -257-



under this Section 3.27(d) is made, or a material non-monetary event of default
exists which is susceptible of cure by the payment of money and for which the
Class SBC Representative is pursuing a cure within the cure period and in
accordance with the terms of this Section 3.27(d), such event of default shall
not be treated as an event of default under the related loan documents by the
Master Servicer or Special Servicer. The right of the Class SBC Representative
to cure a monetary event of default or non-monetary event of default with
respect to the Sturbridge Commons Trust Mortgage Loan shall be limited as
follows: (A) there shall not be more than eight cure events during the term of
the Sturbridge Commons Trust Mortgage Loan and (B) no more than three
consecutive cures of delinquent Monthly Payments are permitted. Each of the
Master Servicer and the Special Servicer shall notify the Class SBC
Representative of any default in respect of the Sturbridge Commons Trust
Mortgage Loan with respect to which the Class SBC Representative is entitled to
exercise cure rights in accordance with this Section 3.27(d), as soon as
reasonably practicable after the Master Servicer or the Special Servicer, as the
case may be, becomes aware of such default (provided that such default has not
been previously remedied). The Class SBC Representative shall be entitled to
reimbursement of any cure payments made by it with respect to the Sturbridge
Commons Trust Mortgage Loan out of amounts subsequently received with respect to
the Sturbridge Commons Trust Mortgage Loan or any related REO Property; provided
that such right to reimbursement is subordinate to the rights of the Trust to
receive all amounts to which it is entitled with respect to the Sturbridge
Commons Trust Mortgage Loan or any successor REO Trust Mortgage Loan with
respect thereto.

          SECTION 3.28.  Defense of Litigation.

          (a) The Special Servicer, consistent with the Servicing Standard,
shall: (i) direct, manage, prosecute and/or defend any action brought by a
Mortgagor against the Trust and/or the Special Servicer; and (ii) represent the
interests of the Trust in any litigation relating to the rights and obligations
of the Mortgagor or the lender, or the enforcement of the obligations of a
Mortgagor, under the subject Mortgage Loan documents ("Trust-Related
Litigation").

          (b) To the extent the Master Servicer is named in Trust-Related
Litigation, and the Trust or Special Servicer is not named, in order to
effectuate the role of the Special Servicer as contemplated by Section 3.28(a)
above, the Master Servicer shall: (i) notify the Special Servicer of such
Trust-Related Litigation within ten (10) days of the Master Servicer receiving
notice of such Trust-Related Litigation; (ii) provide monthly status reports to
the Special Servicer, regarding such Trust-Related Litigation; (iii) seek to
have the Trust replace the Master Servicer as the appropriate party to the
lawsuit; and (iv) so long as the Master Servicer remains a party to the lawsuit,
consult with and act at the direction of the Special Servicer with respect to
decisions and resolutions related to the interests of the Trust in such
Trust-Related Litigation, including but not limited to the selection of counsel,
provided that, if there are claims against the Master Servicer and the Master
Servicer has not determined that separate counsel is required for such claims,
such counsel shall be reasonably acceptable to the Master Servicer.

          (c) Notwithstanding the right of the Special Servicer to represent the
interests of the Trust in Trust-Related Litigation, but subject to the rights of
the Special Servicer to direct the Master Servicer's actions in Section 3.28(d)
below, the Master Servicer shall retain the right to make determinations
relating to claims against the Master Servicer, including but not limited to the
right to engage separate counsel in the Master Servicer's reasonable discretion,
the cost of which shall be subject to indemnification pursuant to Section 6.03.
Further, nothing in this section shall require the Master


                                     -258-



Servicer to take or fail to take any action which, in the Master Servicer's good
faith and reasonable judgment, may (i) result in an Adverse REMIC Event or
Adverse Grantor Trust Event or (ii) subject the Master Servicer to liability or
materially expand the scope of the Master Servicer's obligations under this
Agreement.

          (d) Notwithstanding the Master Servicer's right to make determinations
relating to claims against the Master Servicer, the Special Servicer shall have
the right at any time to (i) direct the Master Servicer to settle any claims
(subject to the consent of the Controlling Class Representative) brought against
the Trust, including claims asserted against the Master Servicer (whether or not
the Trust or the Special Servicer is named in any such claims or Trust-Related
Litigation) and (ii) otherwise reasonably direct the actions of the Master
Servicer relating to claims against the Master Servicer (whether or not the
Trust or the Special Servicer is named in any such claims or Trust-Related
Litigation), provided in either case that (A) such settlement or other direction
does not require any admission, or is not likely to result in a finding, of
liability or wrongdoing on the part of the Master Servicer, (B) the cost of such
settlement or any resulting judgment is and shall be paid by the Trust, (C) the
Master Servicer is and shall be indemnified pursuant to Section 6.03 for all
costs and expenses of the Master Servicer incurred in defending and settling the
Trust-Related Litigation and for any judgment, (D) any such action taken by the
Master Servicer at the direction of the Special Servicer shall be deemed (as to
the Master Servicer) to be in compliance with the Servicing Standard and (E) the
Special Servicer provides the Master Servicer with assurance reasonably

Interest Certificates provided for in Sections 4.01(a) and 4.01(b), the Trustee
shall apply the remaining portion, if any, of the Available Distribution Amount
for such Distribution Date for the following purposes and in the following order
of priority, in each case to the extent of remaining available funds:

               (i) to make distributions to the Holders of the Class R-III
     Certificates, up to an amount equal to the excess, if any, of (A) the
     aggregate distributions (other than distributions of Net Prepayment
     Consideration) deemed made with respect to the REMIC II Regular Interests
     on such Distribution Date pursuant to Section 4.01(l), over (B) the
     aggregate distributions made with respect to the Regular Interest
     Certificates on such Distribution Date pursuant to Section 4.01(a) and/or
     Section 4.01(b);

               (ii) to make distributions to the Holders of the Class R-II
     Certificates, up to an amount equal to the excess, if any, of (A) the
     aggregate distributions (other than distributions of Net Prepayment
     Consideration) deemed made with respect to the REMIC I Regular Interests on
     such Distribution Date pursuant to Section 4.01(m), over (B) the aggregate
     distributions (other than distributions of Net Prepayment Consideration)
     deemed made with respect to the REMIC II Regular Interests on such
     Distribution Date pursuant to Section 4.01(l);

               (iii) subject to Section 2.06(b), to make distributions to the
     Holders of the Class R-LR Certificates, up to an amount equal to the
     excess, if any, of (A) that portion of the Available Distribution Amount
     for such Distribution Date that is allocable to the Early Defeasance Trust
     Mortgage Loans and/or any related REO Properties, over (B) the aggregate
     distributions (other than distributions of Net Prepayment Consideration)
     deemed made with respect to the Loan REMIC Regular Interests on such
     Distribution Date pursuant to Section 4.01(n); and


                                     -267-



               (iv) to distribute to the Holders of the Class R-I Certificates
     the remaining portion, if any, of the Available Distribution Amount.

          (d) On each Distribution Date, through and including the Final
Distribution Date, the Trustee shall withdraw from the Collection Account any
amount Received by the Trust with respect to any Trust Mortgage Loan or REO
Trust Mortgage Loan during the related Collection Period that represents Net
Prepayment Consideration (exclusive, if applicable, of any portion thereof that
constitutes Class HAF Net Prepayment Consideration or Class SBC Net Prepayment
Consideration) and shall distribute such Net Prepayment Consideration: first, to
the Holders of the respective Classes of YM Principal Balance Certificates that
are entitled to distributions of principal on such Distribution Date, pursuant
to Section 4.01(a) or Section 4.01(b), as applicable, with respect to the Loan
Group that includes the prepaid Trust Mortgage Loan or REO Trust Mortgage Loan,
as applicable, up to an amount equal to, and pro rata based on, the respective
Prepayment Consideration Entitlements for such Classes of Certificates for such
Distribution Date in connection with such Net Prepayment Consideration; and
second, to the Holders of the Class X Certificates, in an amount equal to 100%
of any remaining portion of such Net Prepayment Consideration. For purposes of
the foregoing, to the extent that amounts available to make distributions of
principal on any Class of Principal Balance Certificates on any Distribution
Date consist of a combination of principal amounts allocable to both Loan
Groups, the Trustee shall assume that those distributions of principal on that
Class of Principal Balance Certificates on such Distribution Date are made from
principal amounts allocable to each Loan Group, on a pro rata basis in
accordance with the respective principal amounts allocable to each Loan Group
that were available for distributions of principal on that Class. In connection
therewith, (i) distributions of principal made with respect to the Class A-1A
Certificates, pursuant to subclause (i) of clause second of Section 4.01(a), on
any Distribution Date prior to both the Senior Class A Principal Distribution
Cross-Over Date and the Final Distribution Date, shall be deemed made solely
from principal amounts allocable to Loan Group No. 2, and (ii) all other
distributions of principal made with respect to any Class of Principal Balance
Certificates (exclusive of the Loan-Specific Certificates), pursuant to Section
4.01(a) or 4.01(b), on any Distribution Date, shall be deemed made from
principal amounts allocable to both Loan Groups (exclusive of any principal
amounts allocable to Loan Group No. 2 that may have been applied on such
Distribution Date as contemplated by clause (i) of this sentence).

          Any Net Prepayment Consideration or portion thereof distributed with
respect to the Class X Certificates on any Distribution Date shall be deemed to
have been distributed with respect to the respective REMIC III Components of the
Class X Certificates, on a pro rata basis in accordance with the respective
amounts by which the Component Notional Amounts of such REMIC III Components
were reduced on such Distribution Date by deemed distributions of principal
pursuant to Section 4.01(l).

          On each Distribution Date, through and including the Final
Distribution Date, the Trustee shall withdraw from the Collection Account any
amount Received by the Trust during the related Collection Period that
constitutes Class HAF Net Prepayment Consideration with respect to a HAF Split
Trust Mortgage Loan or any successor REO Trust Mortgage Loan with respect
thereto and shall distribute such Class HAF Net Prepayment Consideration to the
Holders of the Class HAF Certificates and, as among the respective Classes of
the Class HAF Certificates, pro rata, based on the amount of principal then
being prepaid with respect to each Class of Class HAF Certificates on such
Distribution Date.


                                     -268-



          On each Distribution Date, through and including the Final
Distribution Date, the Trustee shall withdraw from the Collection Account any
amount Received by the Trust during the related Collection Period that
constitutes Class SBC Net Prepayment Consideration with respect to the
Sturbridge Commons Trust Mortgage Loan or any successor REO Trust Mortgage Loan
with respect thereto and shall distribute such Class SBC Net Prepayment
Consideration to the Holders of the Class SBC Certificates and, as among the
respective Classes of the Class SBC Certificates, pro rata, based on the amount
of principal then being prepaid with respect to each Class of Class SBC
Certificates on such Distribution Date.

          (e) On each Distribution Date, through and including the Final
Distribution Date, subject to Section 2.05(b), the Trustee shall withdraw from
the Collection Account, and distribute to the Holders of the Class V
Certificates, any amounts that represent Additional Interest Received by the
Trust during the related Collection Period with respect to the ARD Trust
Mortgage Loans (and any successor REO Trust Mortgage Loans with respect
thereto).

          (f) On the Final Distribution Date, the Special Servicer shall
withdraw from the Loss of Value Reserve Fund and remit to the Trustee, and (upon
receipt) the Trustee shall distribute to the Holders of the Class R-III
Certificates, any Loss of Value Payments remaining on deposit in the Loss of
Value Reserve Fund as of the Final Distribution Date (after taking into account
any transfer of Loss of Value Payments from the Loss of Value Reserve Fund to
the Collection Account on the immediately preceding Trust Master Servicer
Remittance Date in accordance with Section 3.05(e)).

          (g) All distributions made with respect to each Class of Certificates
on each Distribution Date shall be allocated pro rata among the outstanding
Certificates in such Class based on their respective Percentage Interests.
Except as otherwise provided below, all such distributions with respect to each
Class on each Distribution Date shall be made to the Certificateholders of the
respective Class of record at the close of business on the related Record Date
and shall be made by wire transfer of immediately available funds to the account
of any such Certificateholder at a bank or other entity having appropriate
facilities therefor, if such Certificateholder shall have provided the Trustee
with wiring instructions no less than five (5) Business Days prior to the
related Record Date or, in the case of the initial Distribution Date, no later
than the close of business on the later of (i) the fifth Business Day prior to
the related Record Date and (ii) the Closing Date (which wiring instructions may
be in the form of a standing order applicable to all subsequent Distribution
Dates), or otherwise by check mailed to the address of such Certificateholder as
it appears in the Certificate Register. The final distribution on each
Certificate (determined, in the case of a Principal Balance Certificate, without
regard to any possible future reimbursement of any related Loss Reimbursement
Amount) will be made in a like manner, but only upon presentation and surrender
of such Certificate at the offices of the Certificate Registrar or such other
location specified in the notice to Certificateholders of such final
distribution. Prior to any termination of the Trust Fund pursuant to Section
9.01, any distribution that is to be made with respect to a Certificate in
reimbursement of any related Loss Reimbursement Amount, which reimbursement is
to occur after the date on which such Certificate is surrendered as contemplated
by the preceding sentence, will be made by check mailed to the address of the
Certificateholder that surrendered such Certificate as such address last
appeared in the Certificate Register or to any other address of which the
Trustee was subsequently notified in writing. If such check is returned to the
Trustee, then the Trustee, directly or through an agent, shall take such
reasonable steps to contact the related Holder and deliver such check as it
shall deem appropriate. Any funds in respect of a check returned to the Trustee
shall be set aside by the Trustee and held uninvested in trust and credited to
the account of the appropriate


                                     -269-



Holder. The costs and expenses of locating the appropriate Holder and holding
such funds shall be paid out of such funds. No interest shall accrue or be
payable to any former Holder on any amount held in trust hereunder. If the
Trustee has not, after having taken such reasonable steps, located the related
Holder by the second anniversary of the initial sending of a check, the Trustee
shall, subject to applicable law, distribute the unclaimed funds to the Class
R-III Certificateholders.

          (h) Each distribution with respect to a Book-Entry Certificate shall
be paid to the Depository, as Holder thereof, and the Depository shall be
responsible for crediting the amount of such distribution to the accounts of its
Depository Participants in accordance with its normal procedures. Each
Depository Participant shall be responsible for disbursing such distribution to
the related Certificate Owners that it represents and to each indirect
participating brokerage firm for which it acts as agent. Each indirect
participating brokerage firm shall be responsible for disbursing funds to the
related Certificate Owners that it represents. None of the Trustee, the
Certificate Registrar, the Depositor or the Master Servicer shall have any
responsibility therefor except as otherwise provided by this Agreement or
applicable law. The Trustee and the Depositor shall perform their respective
obligations under each Letter of Representations among the Depositor, the
Trustee and the initial Depository dated as of the Closing Date and pertaining
to the Book-Entry Certificates.

          (i) The rights of the Certificateholders to receive distributions from
the proceeds of the Trust Fund with respect to the Certificates, and all rights
and interests of the Certificateholders in and to such distributions, shall be
as set forth in this Agreement. Neither the Holders of any Class of Certificates
nor any party hereto shall in any way be responsible or liable to the Holders of
any other Class of Certificates with respect to amounts properly previously
distributed on the Certificates.

          (j) Except as otherwise provided in Section 9.01, whenever the Trustee
receives written notification of or expects that the final distribution with
respect to any Class of Certificates (determined, in the case of a Class of
Principal Balance Certificates, without regard to any possible future
reimbursement of any related Loss Reimbursement Amount) will be made on the next
Distribution Date, the Trustee shall, as soon as reasonably practicable and, in
any event, no later than the second Business Day prior to such Distribution
Date, mail to each Holder of record of such Class of Certificates on such date a
notice to the effect that:

               (i) the Trustee expects that the final distribution with respect
     to such Class of Certificates will be made on such Distribution Date but
     only upon presentation and surrender of such Certificates at the office of
     the Certificate Registrar or at such other location therein specified, and

               (ii) no interest shall accrue on such Certificates from and after
     the end of the Interest Accrual Period for such Distribution Date.

Any funds not distributed to any Holder or Holders of Certificates of such Class
on such Distribution Date because of the failure of such Holder or Holders to
tender their Certificates shall, on such date, be set aside and held uninvested
in trust and credited to the account or accounts of the appropriate
non-tendering Holder or Holders. If any Certificates as to which notice has been
given pursuant to this Section 4.01(j) shall not have been surrendered for
cancellation within six months after the time specified in such notice, the
Trustee shall mail a second notice to the remaining non-tendering
Certificateholders to surrender their Certificates for cancellation in order to
receive the final distribution with respect thereto. If within one year after
the second notice all such Certificates shall not have been


                                     -270-



surrendered for cancellation, then the Trustee, directly or through an agent,
shall take such steps to contact the remaining non-tendering Certificateholders
concerning the surrender of their Certificates as it shall deem appropriate. The
costs and expenses of holding such funds in trust and of contacting such
non-tendering Certificateholders following the first anniversary of the delivery
of such second notice thereto shall be paid out of such funds. No interest shall
accrue or be payable to any former Holder on any amount held in trust pursuant
to this paragraph. If all of the Certificates as to which notice has been given
pursuant to this Section 4.01(j) shall not have been surrendered for
cancellation by the second anniversary of the delivery of the second notice, the
Trustee shall, subject to applicable law, distribute to the Class R-III
Certificateholders all unclaimed funds and other assets which remain subject
thereto.

          (k) Notwithstanding any other provision of this Agreement, the Trustee
shall comply with all federal withholding requirements respecting payments to
Certificateholders of interest or original issue discount that the Trustee
reasonably believes are applicable under the Code. The consent of
Certificateholders shall not be required for such withholding. If the Trustee
does withhold any amount from interest or original issue discount payments or
advances thereof to any Certificateholder pursuant to federal withholding
requirements, the Trustee shall indicate the amount withheld to such
Certificateholder.

          (l) All distributions made in respect of each Class of Principal
Balance Certificates on each Distribution Date (including the Final Distribution
Date) pursuant to Section 4.01(a), Section 4.01(b) or Section 4.01(d) shall be
deemed to have first been distributed on such Distribution Date from REMIC II to
REMIC III with respect to the Corresponding REMIC II Regular Interest(s) for
such Class of Certificates; and all distributions made with respect to the
Interest-Only Certificates on each Distribution Date pursuant to Section 4.01(a)
or Section 4.01(d) and allocable to any particular REMIC III Component of such
Class of Certificates, shall be deemed to have first been distributed on such
Distribution Date from REMIC II to REMIC III in respect of the Corresponding
REMIC II Regular Interest for such REMIC III Component. In each case, if such
distribution on any such Class of Certificates was a distribution of accrued
interest, of principal, of additional interest (in the form of Net Prepayment
Consideration or any portion thereof) or in reimbursement of any Loss
Reimbursement Amount with respect to such Class of Certificates, then the
corresponding distribution deemed to be made on a REMIC II Regular Interest
pursuant to the preceding sentence (and, if applicable, the following paragraph
of this Section 4.01(l)) shall be deemed to also be, respectively, a
distribution of accrued interest, of principal, of additional interest (in the
form of Net Prepayment Consideration or any portion thereof) or in reimbursement
of any Loss Reimbursement Amount with respect to such REMIC II Regular Interest.

          If a Class of Principal Balance Certificates has two or more
Corresponding REMIC II Regular Interests, then:

               (i) deemed distributions of accrued interest made on such
     Corresponding REMIC II Regular Interests on any Distribution Date shall be
     allocated between or among them, as applicable, on a pro rata basis in
     accordance with the respective amounts of Uncertificated Distributable
     Interest in respect of such Corresponding REMIC II Regular Interests for
     such Distribution Date and, to the extent not previously deemed
     distributed, for all prior Distribution Dates, if any;


                                     -271-



               (ii) deemed distributions of principal made on such Corresponding
     REMIC II Regular Interests on any Distribution Date shall be allocated to
     them in numeric order (i.e., from lowest number to highest number) of the
     respective ending numbers of the respective alphanumeric designations for
     such Corresponding REMIC II Regular Interests, in each case up to an amount
     equal to the Uncertificated Principal Balance of the subject Corresponding
     REMIC II Regular Interest outstanding immediately prior to such
     Distribution Date (such that no deemed distributions of principal will be
     made on any such Corresponding REMIC II Regular Interest until the
     Uncertificated Principal Balance of each other such Corresponding REMIC II
     Regular Interest, if any, with an alphanumeric designation that ends in a
     lower number, has been paid in full);

               (iii) deemed distributions of additional interest (in the form of
     Net Prepayment Consideration or any portion thereof) made on such
     Corresponding REMIC II Regular Interests on any Distribution Date shall be
     allocated between or among them, as applicable, on a pro rata basis in
     accordance with the respective amounts of principal deemed distributed in
     respect of such Corresponding REMIC II Regular Interests on such
     Distribution Date; and

               (iv) deemed distributions made on such Corresponding REMIC II
     Regular Interests on any Distribution Date in reimbursement of the Loss
     Reimbursement Amounts with respect thereto shall be allocated to them in
     the same order that deemed distributions of principal made on such
     Corresponding REMIC II Regular Interests are allocated to them pursuant to
     subclause (ii) of this paragraph, in each case up to the amount of the Loss
     Reimbursement Amount with respect to the subject REMIC II Regular Interest
     for such Distribution Date.

          The actual distributions made by the Trustee on each Distribution Date
in respect of the REMIC III Certificates pursuant to Section 4.01(a), Section
4.01(b), Section 4.01(c) or Section 4.01(d), as applicable, shall be deemed to
have been so made from the amounts deemed distributed with respect to the REMIC
II Regular Interests on such Distribution Date pursuant to this Section 4.01(l).
Notwithstanding the deemed distributions on the REMIC II Regular Interests
described in this Section 4.01(l), actual distributions of funds from the
Collection Account shall be made only in accordance with Section 4.01(a),
Section 4.01(b), Section 4.01(c), Section 4.01(d) or Section 4.01(e), as
applicable.

          (m) On each Distribution Date, through and including the Final
Distribution Date, the STML Available Distribution Amount with respect to any
Split Trust Mortgage Loan or Split REO Trust Mortgage Loan for such Distribution
Date shall be deemed to have been distributed from REMIC I to REMIC II for the
following purposes and in the following order of priority, in each case to the
extent of the remainder of such funds:

               (i) as deemed distributions of interest with respect to the
     related STML Group A REMIC I Regular Interest, up to an amount equal to all
     Uncertificated Distributable Interest with respect to such REMIC I Regular
     Interest for such Distribution Date and, to the extent not previously
     deemed distributed, for all prior Distribution Dates, if any;

               (ii) as deemed distributions of principal with respect to the
     related STML Group A REMIC I Regular Interest, up to an amount (not to
     exceed the Uncertificated Principal Balance of such REMIC I Regular
     Interest immediately prior to such Distribution Date) equal to


                                     -272-



     either (A) if an STML Payment Application Trigger Event does not exist with
     respect to such Split Trust Mortgage Loan or Split REO Trust Mortgage Loan,
     as the case may be, the product of (1) the STML Principal Distribution
     Amount with respect to such Split Trust Mortgage Loan or Split REO Trust
     Mortgage Loan, as the case may be, for such Distribution Date, multiplied
     by (2) a fraction, the numerator of which is the Uncertificated Principal
     Balance of the related STML Group A REMIC I Regular Interest immediately
     prior to such Distribution Date, and the denominator of which is the Stated
     Principal Balance of such Split Trust Mortgage Loan or Split REO Trust
     Mortgage Loan, as the case may be, immediately prior to such Distribution
     Date, or (B) if an STML Payment Application Trigger Event does exist with
     respect to such Split Trust Mortgage Loan or Split REO Trust Mortgage Loan,
     as the case may be, the entire STML Principal Distribution Amount with
     respect to such Split Trust Mortgage Loan or Split REO Trust Mortgage Loan,
     as the case may be, for such Distribution Date;

               (iii) as deemed distributions of reimbursement with respect to
     the related STML Group A REMIC I Regular Interest, up to an amount equal to
     any Loss Reimbursement Amount with respect to such REMIC I Regular Interest
     for such Distribution Date (with compounded interest at the related REMIC I
     Remittance Rate in effect from time to time on the aggregate amount of
     unreimbursed reductions made from time to time in the Uncertificated
     Principal Balance of such REMIC I Regular Interest pursuant to Section
     4.04(c));

               (iv) as deemed distributions of interest with respect to the
     related STML Group B REMIC I Regular Interest, up to an amount equal to all
     Uncertificated Distributable Interest with respect to such REMIC I Regular
     Interest for such Distribution Date and, to the extent not previously
     deemed distributed, for all prior Distribution Dates, if any;

               (v) as deemed distributions of principal with respect to the
     related STML Group B REMIC I Regular Interest, up to an amount (not to
     exceed the Uncertificated Principal Balance of such REMIC I Regular
     Interest outstanding immediately prior to such Distribution Date) equal to
     the excess, if any, of (A) the STML Principal Distribution Amount with
     respect to such Split Trust Mortgage Loan or Split REO Trust Mortgage Loan,
     as the case may be, for such Distribution Date, over (B) all distributions
     of principal deemed to be made with respect to the related STML Group A
     REMIC I Regular Interest on such Distribution Date pursuant to clause (ii)
     of this Section 4.01(m); and

               (vi) as deemed distributions of reimbursement with respect to the
     related STML Group B REMIC I Regular Interest, up to an amount equal to the
     Loss Reimbursement Amount with respect to such REMIC I Regular Interest for
     such Distribution Date (with compounded interest at the related REMIC I
     Remittance Rate in effect from time to time on the aggregate amount of
     unreimbursed reductions made from time to time in the Uncertificated
     Principal Balance of such REMIC I Regular Interest pursuant to Section
     4.04(c));

provided that, if any amounts that would otherwise constitute part of the STML
Available Distribution Amount with respect to any Split Trust Mortgage Loan or
any successor REO Trust Mortgage Loan with respect thereto for any Distribution
Date are applied to pay or reimburse any Nonrecoverable Advance or Additional
Trust Fund Expense with respect to any Mortgage Loan or REO Property other than
such Split Trust Mortgage Loan or any related REO Property, then such amounts
shall be deemed to be distributed on such Distribution Date from REMIC I to
REMIC II with respect to, and in satisfaction of


                                     -273-



amounts payable on, the related STML Group A REMIC I Regular Interest pursuant
to clauses (i), (ii) and (iii) above as interest, principal and loss
reimbursement, respectively, and prior to any application of the actual
available funds constituting such STML Available Distribution Amount.

          On each Distribution Date, through and including the Final
Distribution Date, the Available Distribution Amount (exclusive of amounts
distributed pursuant to the preceding paragraph) for such Distribution Date
shall be deemed to have been distributed from REMIC I to REMIC II for the
following purposes and in the following order of priority, in each case to the
extent of the remainder of such funds:

               (i) as deemed distributions of interest with respect to all the
     REMIC I Regular Interests (exclusive of the STML Group A REMIC I Regular
     Interests and the STML Group B REMIC I Regular Interests), up to an amount
     equal to, and pro rata in accordance with, all Uncertificated Distributable
     Interest with respect to each such REMIC I Regular Interest for such
     Distribution Date and, to the extent not previously deemed distributed, for
     all prior Distribution Dates, if any;

               (ii) as deemed distributions of principal with respect to all the
     REMIC I Regular Interests (exclusive of the STML Group A REMIC I Regular
     Interests and the STML Group B REMIC I Regular Interests), up to an amount
     equal to, and pro rata in accordance with, as to each such REMIC I Regular
     Interest, the portion of the Principal Distribution Amount for such
     Distribution Date attributable to the related Trust Mortgage Loan or any
     successor REO Trust Mortgage Loan with respect thereto; and

               (iii) as deemed distributions of reimbursement with respect to
     all the REMIC I Regular Interests (exclusive of the STML Group A REMIC I
     Regular Interests and the STML Group B REMIC I Regular Interests), up to an
     amount equal to, and pro rata in accordance with, any Loss Reimbursement
     Amount with respect to each such REMIC I Regular Interest for such
     Distribution Date (with compounded interest at the related REMIC I
     Remittance Rate in effect from time to time on the aggregate amount of
     unreimbursed reductions made from time to time in the Uncertificated
     Principal Balance of the subject REMIC I Regular Interest pursuant to
     Section 4.04(c)).

          Any Net Prepayment Consideration distributed to any Class of Regular
Interest Certificates on any Distribution Date shall, in each case, be deemed to
have been distributed on such Distribution Date from REMIC I to REMIC II in
respect of the REMIC I Regular Interest(s) corresponding to the prepaid Trust
Mortgage Loan or REO Trust Mortgage Loan, as the case may be, in respect of
which such Net Prepayment Consideration was received.

          The actual distributions made by the Trustee on each Distribution Date
in respect of the REMIC III Certificates and the Class R-II Certificates
pursuant to Section 4.01(a), Section 4.01(b), Section 4.01(c) or Section
4.01(d), as applicable, as well as the deemed distributions made on each
Distribution Date in respect of the REMIC II Regular Interests pursuant to
Section 4.01(l), shall be deemed to have been so made from the amounts deemed
distributed with respect to the REMIC I Regular Interests on such Distribution
Date pursuant to this Section 4.01(m). Notwithstanding the deemed distributions
on the REMIC I Regular Interests described in this Section 4.01(m), actual
distributions of funds from the Collection Account shall be made only in
accordance with Section 4.01(a), Section 4.01(b), Section 4.01(c), Section
4.01(d) or Section 4.01(e), as applicable.


                                     -274-



          (n) On each Distribution Date, through and including the Final
Distribution Date, any portion of the Available Distribution Amount for such
date allocable to an Early Defeasance Trust Mortgage Loan (or any successor REO
Trust Mortgage Loan with respect thereto) shall be deemed to have first been
distributed from the related Loan REMIC to REMIC I in respect of the
corresponding Loan REMIC Regular Interest, in each case to the extent of the
remaining portions of such funds, for the following purposes and in the
following order of priority:

               (i) as deemed distributions of interest in respect of the related
     Loan REMIC Regular Interest, up to an amount equal to all Uncertificated
     Distributable Interest in respect of such Loan REMIC Regular Interest for
     such Distribution Date and, to the extent not previously deemed
     distributed, for all prior Distribution Dates, if any;

               (ii) as deemed distributions of principal in respect of the
     related Loan REMIC Regular Interest, up to an amount equal to the portion
     of the Principal Distribution Amount for such Distribution Date
     attributable to such Early Defeasance Trust Mortgage Loan (or any successor
     REO Trust Mortgage Loan with respect thereto); and

               (iii) as deemed distributions of reimbursement with respect to
     the related Loan REMIC Regular Interest, up to an amount equal to any Loss
     Reimbursement Amount with respect to the related Loan REMIC Regular

to such Certificateholder during such calendar year (or the applicable portion
of such calendar year during which such Person was a Certificateholder) set
forth in the Distribution Date Statements and such other information as may be
required to enable such Certificateholder to prepare its federal income tax
returns. Such information shall include the amount of original issue discount
accrued on each Class of Certificates and information regarding the expenses of
the Trust Fund. Such requirement shall be deemed to be satisfied to the extent
such information is provided pursuant to applicable requirements of the Code
from time to time in force.

          (f) Upon receipt of notice from the Depositor that the Underwriters
have sold the Non-Registered Certificates to unaffiliated third parties, the
Trustee shall make available electronically or, if so requested, forward by hard
copy, on each Distribution Date, to (i) Trepp, LLC (at 477 Madison Avenue, 18th
Floor, New York, New York 10022 or such other address as Trepp, LLC may
designate), (ii) Intex Solutions, Inc. (at 110 A Street, Needham, Massachusetts
02494, or such other address as Intex Solutions, Inc. may hereafter designate),
(iii) Charter Research Corporation (at Two Oliver Street, 10th Floor, Boston,
Massachusetts 02109-4904, or such other address as Charter Research Corporation
may hereafter designate), and (iv) any other similar third party information
provider designated by the Depositor, a copy of the reports made available to
the Holders of the Certificates on such Distribution Date as described above.

          (g) Upon written request of the Depositor or any Underwriter, without
payment of any fee, and upon written request of any Certificateholder or any
other Person, together with payment of a reasonable fee specified by the
Trustee, the Trustee shall provide any statements, reports and/or information
contemplated by this Section 4.02 electronically to such party (such electronic
distribution and such statements, reports, and/or information thereon to bear
such appropriate disclaimers and qualifications as the Depositor and the Trustee
shall determine in their reasonable discretion).

          If any Certificate Owner does not receive through the Depository or
any of its Depository Participants any of the statements, reports and/or other
written information described above in this Section 4.02 that it would otherwise
be entitled to receive if it were the Holder of a Definitive Certificate
evidencing its ownership interest in the related Class of Book-Entry
Certificates, then the Trustee shall forward such statements, reports and/or
other written information to such Certificate Owner as provided above, upon the
request of such Certificate Owner made in writing to the Corporate Trust Office
(accompanied by current verification of such Certificate Owner's ownership
interest). Such portion of such information as may be agreed upon by the
Depositor and the Trustee shall be furnished to any such Person via overnight
courier delivery or telecopy from the Trustee; provided that the cost of such
overnight courier delivery or telecopy shall be an expense of the party
requesting such information.


                                     -283-



          (h) The Trustee shall only be obligated to deliver the statements,
reports and information contemplated by this Section 4.02 to the extent it
receives, in the format required by this Agreement, the necessary underlying
information from the Master Servicer or the Special Servicer, as applicable, and
shall not be liable for any failure to deliver any thereof on the prescribed due
dates, to the extent caused by failure to receive timely such underlying
information. Nothing herein shall obligate the Trustee, the Master Servicer or
the Special Servicer to violate any applicable law prohibiting disclosure of
information with respect to any Mortgagor and the failure of the Trustee, Master
Servicer or the Special Servicer to disseminate information for such reason
shall not be a breach hereof.

          (i) The information to be furnished by the Trustee to the
Certificateholders pursuant to this Section 4.02 shall not limit the Trustee in
furnishing any such information to other Persons to whom it determines such
disclosure to be appropriate and shall not limit the Trustee in furnishing to
Certificateholders or to any Person any other information with respect to the
Trust Mortgage Loans, the Mortgaged Properties or the Trust Fund as may be
provided to it by the Depositor, the Master Servicer or the Special Servicer or
gathered by it in any investigation or other manner from time to time (such
information, other than as described in this Section 4.02, is referred to herein
as "Additional Information") as it may reasonably deem necessary or appropriate
from time to time, provided that (A) the Trustee shall give the Depositor three
(3) Business Days' advance notice before doing so, (B) any such Additional
Information shall only be furnished with the consent or at the request of the
Depositor (except pursuant to clause (E) below), (C) the Trustee shall be
entitled to indicate the source of all information furnished by it, and the
Trustee may affix thereto any disclaimer it deems appropriate in its reasonable
discretion, (D) the Trustee shall notify Certificateholders of the availability
of any such information in any manner as it, in its sole discretion, may
determine, and (E) this provision shall not prevent the Trustee, whether with or
without the consent of the Depositor, from furnishing information with respect
to the Trust Fund and its administration thereof to any Person, if it reasonably
determines that the furnishing of such information is required by applicable
law. The Trustee shall forward to the Depositor any requests for Additional
Information which, for their fulfillment, require the consent of the Depositor.
Nothing herein shall be construed to impose upon the Trustee any obligation or
duty to furnish or distribute any Additional Information to any Person in any
instance.

          SECTION 4.03.  P&I Advances With Respect to the Mortgage Pool.

          (a) On or before 2:00 p.m., New York City time, on each Trust Master
Servicer Remittance Date, the Master Servicer shall, subject to Section 4.03(c)
below, satisfy its obligations to make any required P&I Advances with respect to
the related Distribution Date in respect of the Mortgage Pool, first, by
transferring to the Trustee for deposit in the Collection Account amounts then
held in the Pool Custodial Account for future distribution to Certificateholders
in subsequent months in discharge of such obligations, and second, by remitting
its own funds to the Trustee for deposit in the Collection Account in an amount
equal to the remaining portion of such required P&I Advances. Any amounts held
in the Pool Custodial Account for future distribution and so used to make P&I
Advances shall be appropriately reflected in the Master Servicer's records and
replaced by the Master Servicer by deposit in the Pool Custodial Account on or
before the next succeeding applicable Determination Date (to the extent not
previously replaced through the deposit of Late Collections of the delinquent
principal and interest in respect of which such P&I Advances were made). If, as
of 4:00 p.m., New York City time, on any Trust Master Servicer Remittance Date,
the Master Servicer shall not have made any P&I Advance required to be made on
such date pursuant to this Section 4.03(a) (and shall not have delivered to the
Trustee the requisite Officer's Certificate and any required supporting
documentation related to a


                                     -284-



determination of nonrecoverability of a P&I Advance), then the Trustee shall
provide notice of such failure to a Servicing Officer of the Master Servicer by
facsimile transmission sent to telecopy no. (704) 715-0036 (or such alternative
number provided by the Master Servicer to the Trustee in writing) and by
telephone at telephone no. (704) 593-7768 or (704) 593-7732 (or such alternative
number provided by the Master Servicer to the Trustee in writing) as soon as
possible, but in any event before 5:00 p.m., New York City time, on such Trust
Master Servicer Remittance Date. If after such notice by facsimile, the Trustee
does not receive the full amount of such P&I Advances by 10:00 a.m., New York
City time, on the related Distribution Date, then the Trustee (or any Fiscal
Agent on its behalf) shall make the portion of such P&I Advances that was
required to be, but was not, made by the Master Servicer on such Trust Master
Servicer Remittance Date. If the Trustee fails to make any such P&I Advance on
the related Distribution Date, but a Fiscal Agent makes such P&I Advance on such
date, then the Trustee shall be deemed not to be in default hereunder.

          No party hereto shall be required to make a P&I Advance with respect
to any Non-Trust Mortgage Loan or any successor REO Mortgage Loan with respect
thereto.

          (b) The aggregate amount of P&I Advances to be made by the Master
Servicer, the Trustee or any Fiscal Agent, as the case may be, pursuant to this
Section 4.03 in respect of any Distribution Date shall, subject to Section
4.03(c) below, equal the aggregate of all Monthly Payments (other than Balloon
Payments) and any Assumed Monthly Payments, in each case net of related Master
Servicing Fees and Workout Fees (and, in the case of each Outside Serviced Trust
Mortgage Loan or any successor REO Trust Mortgage Loan with respect thereto,
further net of any related similar fees payable to third parties with respect to
the subject Outside Serviced Trust Mortgage Loan or any successor REO Trust
Mortgage Loan with respect thereto pursuant to the related Outside Servicing
Agreement) due or deemed due, as the case may be, in respect of the Trust
Mortgage Loans (including Balloon Trust Mortgage Loans delinquent as to their
respective Balloon Payments) and any REO Trust Mortgage Loans in the Mortgage
Pool on their respective Due Dates during the calendar month in which the
subject Distribution Date occurs, in each case to the extent such amount was not
Received by the Trust (including as net income from any related REO Property) as
of the end of the related Collection Period; provided that--

               (i) if it is determined by the applicable Outside Servicer and
     reported to the applicable parties hereunder that an Appraisal Reduction
     Amount exists with respect to any Outside Serviced Loan Combination, and a
     portion of such Appraisal Reduction Amount is allocable to the Trust
     Mortgage Loan or any successor REO Trust Mortgage Loan with respect
     thereto, as applicable, that is part of such Outside Serviced Loan
     Combination, then the interest portion of each P&I Advance, if any,
     required to be made pursuant to this Section 4.03 with respect to such
     Trust Mortgage Loan or any successor REO Trust Mortgage Loan with respect
     thereto, as the case may be, during the period that such Appraisal
     Reduction Amount continues to exist, shall be reduced to equal the product
     of (A) the amount of the interest portion of the subject P&I Advance that
     would otherwise be required to be made under this Section 4.03 with respect
     to such Trust Mortgage Loan or any successor REO Trust Mortgage Loan with
     respect thereto, as the case may be, without regard to this proviso,
     multiplied by (B) a fraction, the numerator of which is equal to the Stated
     Principal Balance of such Trust Mortgage Loan or any successor REO Trust
     Mortgage Loan with respect thereto, as the case may be, reduced (to not
     less than zero) by the portion of any Appraisal Reduction Amount in respect
     of the subject Outside Serviced Loan Combination that is allocable to such
     Trust Mortgage Loan or any


                                     -285-



     successor REO Trust Mortgage Loan with respect thereto, as the case may be,
     and the denominator of which is equal to the then Stated Principal Balance
     of such Trust Mortgage Loan or any successor REO Trust Mortgage Loan with
     respect thereto, as the case may be;

               (ii) if it is determined that an Appraisal Reduction Amount
     exists with respect to any Serviced Loan Combination and, further, that a
     portion of such Appraisal Reduction Amount is allocable to the Trust
     Mortgage Loan or REO Trust Mortgage Loan, as applicable, that is part of
     such Serviced Loan Combination, then the interest portion of each P&I
     Advance, if any, required to be made pursuant to this Section 4.03 with
     respect to such Trust Mortgage Loan or REO Trust Mortgage Loan, as the case
     may be, during the period that such Appraisal Reduction Amount continues to
     exist, shall be reduced to equal the product of (A) the amount of the
     interest portion of the subject P&I Advance that would otherwise be
     required to be made under this Section 4.03 with respect to such Trust
     Mortgage Loan or REO Trust Mortgage Loan, as the case may be, without
     regard to this proviso, multiplied by (B) a fraction, the numerator of
     which is equal to the then Stated Principal Balance of such Trust Mortgage
     Loan or REO Trust Mortgage Loan, as the case may be, reduced (to not less
     than zero) by the portion of such Appraisal Reduction Amount with respect
     to the subject Serviced Loan Combination that is allocable to such Trust
     Mortgage Loan or REO Trust Mortgage Loan, as the case may be, and the
     denominator of which is equal to the then Stated Principal Balance of such
     Trust Mortgage Loan or REO Trust Mortgage Loan, as the case may be; and

               (iii) if it is determined that an Appraisal Reduction Amount
     exists with respect to any Trust Mortgage Loan or REO Trust Mortgage Loan
     that is not part of a Loan Combination, then the interest portion of each
     P&I Advance, if any, required to be made pursuant to this Section 4.03 with
     respect to such Trust Mortgage Loan or REO Trust Mortgage Loan, as the case
     may be, during the period that such Appraisal Reduction Amount continues to
     exist, shall be reduced to equal the product of (A) the amount of the
     interest portion of the subject P&I Advance that would otherwise be
     required to be made under this Section 4.03 in respect of such Trust
     Mortgage Loan or REO Trust Mortgage Loan, as the case may be, without
     regard to this proviso, multiplied by (B) a fraction, the numerator of
     which is equal to the then Stated Principal Balance of such Trust Mortgage
     Loan or REO Trust Mortgage Loan, as the case may be, reduced (to not less
     than zero) by such Appraisal Reduction Amount, and the denominator of which
     is equal to the then Stated Principal Balance of such Trust Mortgage Loan
     or REO Trust Mortgage Loan, as the case may be;

and provided, further, that the existence of an Appraisal Reduction Amount with
respect to, or that is allocable to, any Trust Mortgage Loan or REO Trust
Mortgage Loan shall not affect the principal portion of any required P&I Advance
with respect thereto.

          For purposes of determining the amount of P&I Advances to be made with
respect to any Distribution Date, if an Appraisal Reduction Amount exists with
respect to any Serviced Loan Combination, then such Appraisal Reduction Amount
shall be allocated between the Mortgage Loans or REO Mortgage Loans, as
applicable, in the subject Loan Combination as follows:

               (i) with respect to a Serviced Pari Passu Loan Combination (if
     any), any Appraisal Reduction Amount shall be allocated, first, to any
     related Serviced Subordinate Non-Trust Mortgage Loan (or any successor REO
     Mortgage Loan with respect thereto) (up to


                                     -286-



     the amount of the outstanding principal balance of, and all accrued and
     unpaid interest (other than Default Interest) on, such Serviced Subordinate
     Non-Trust Mortgage Loan (or any successor REO Mortgage Loan with respect
     thereto), and then, on a pro rata basis by principal balance, between the
     related Serviced Combination Trust Mortgage Loan and the related Serviced
     Pari Passu Non-Trust Mortgage Loan (or between any successor REO Mortgage
     Loans with respect thereto); and

               (ii) with respect to any Serviced A/B Loan Combination, any
     Appraisal Reduction Amount shall be allocated, first, to the related
     Serviced Subordinate Non-Trust Mortgage Loan (or any successor REO Mortgage
     Loans with respect thereto) (up to the amount of the outstanding principal
     balance of, and all accrued and unpaid interest (other than Default
     Interest) on, such Serviced Subordinate Non-Trust Mortgage Loan (or any
     successor REO Mortgage Loan with respect thereto)), and then, to the
     related Serviced Combination Trust Mortgage Loan (or any successor REO
     Mortgage Loan with respect thereto).

          If the Master Servicer, the Trustee or any Fiscal Agent makes a P&I
Advance with respect to an Outside Serviced Trust Mortgage Loan or any successor
REO Trust Mortgage Loan with respect thereto, then it shall promptly so notify
the related Outside Master Servicer of each such P&I Advance so made thereby and
shall seek reimbursement for such P&I Advance (together with interest thereon)
out of amounts otherwise payable with respect to the Outside Serviced Loan
Combination that includes such Outside Serviced Trust Mortgage Loan or any
successor REO Trust Mortgage Loan with respect thereto, to the maximum extent
permitted by, and out of amounts specified for such purpose under, the related
Co-Lender Agreement and/or the related Outside Servicing Agreement.

          (c) Notwithstanding anything herein to the contrary, no P&I Advance
shall be required to be made under this Section 4.03 if such P&I Advance would,
if made, constitute a Nonrecoverable P&I Advance. The Trustee and any Fiscal
Agent shall be entitled to rely, conclusively, on any determination by the
Master Servicer that a P&I Advance, if made pursuant to this Section 4.03, would
be a Nonrecoverable P&I Advance; provided, however, that if the Master Servicer
has failed to make a P&I Advance pursuant to this Section 4.03 for reasons other
than a determination by the Master Servicer that such P&I Advance would be a
Nonrecoverable P&I Advance or for the reasons contemplated by the following
paragraphs of this Section 4.03(c), the Trustee or any Fiscal Agent shall make
such Advance within the time periods required by Section 4.03(a) unless the
Trustee or such Fiscal Agent, in its good faith, reasonable discretion, makes a
determination prior to the times specified in Section 4.03(a) that such P&I
Advance would be a Nonrecoverable P&I Advance. Upon determining that any P&I
Advance previously made or proposed to be made pursuant to this Section 4.03
with respect to any Serviced Trust Mortgage Loan or, if related to an
Administered REO Property, any REO Trust Mortgage Loan is or would, if made,
constitute a Nonrecoverable P&I Advance, the Special Servicer shall report its
determination to the Master Servicer, the Trustee and any Fiscal Agent. The
Master Servicer, the Trustee and any Fiscal Agent shall rely on any
determination by the Special Servicer that a P&I Advance made or proposed to be
made pursuant to this Section 4.03 with respect to any Serviced Trust Mortgage
Loan or, if related to an Administered REO Property, any REO Trust Mortgage Loan
would be a Nonrecoverable P&I Advance. Any determination by the Master Servicer
or the Special Servicer that the Master Servicer has made a Nonrecoverable P&I
Advance pursuant to this Section 4.03, or that any proposed P&I Advance, if made
pursuant to this Section 4.03, would constitute a Nonrecoverable P&I Advance,
shall be evidenced by an Officer's Certificate delivered to the Trustee, any
Fiscal Agent and the Depositor (and, if such determination is made by the
Special Servicer or the


                                     -287-



Master Servicer, to the other such servicer) on or before the related Trust
Master Servicer Remittance Date, setting forth the basis for such determination,
together with any other information that supports such determination, including
an appraisal (which appraisal shall have been conducted by an Independent
Appraiser within the 12-month period preceding such determination in accordance
with the standards of the Appraisal Institute taking into account the factors
specified in Section 3.18 or, alternatively, in the case of an Outside Serviced
Trust Mortgage Loan or any successor REO Trust Mortgage Loan with respect
thereto, shall either have been conducted by an Independent Appraiser as
provided above or received from a related Outside Servicer), related Mortgagor
operating statements and financial statements, budgets and rent rolls of the
related Mortgaged Properties (to the extent available and/or in the Master
Servicer's or the Special Servicer's possession), engineers' reports,
environmental surveys and any similar reports that the Master Servicer may have
obtained consistent with the Servicing Standard and at the expense of the Trust
Fund, that support such determination by the Master Servicer or the Special
Servicer, as applicable. If, in connection with the foregoing, it is necessary
for the Master Servicer to obtain an appraisal, the Master Servicer shall so
notify the Special Servicer and consult with the Special Servicer regarding such
appraisal. In determining whether any P&I Advance constitutes a Nonrecoverable
P&I Advance, the Master Servicer and the Special Servicer shall each be entitled
to consider (among other things) the obligations of the related Mortgagor under
the terms of the related Mortgage Loan (as such terms may have been modified),
to consider (among other things) the related Mortgaged Property in its "as is"
or then current condition and with respect to its then current occupancies, all
as modified by such party's reasonable assumptions (consistent with the
Servicing Standard) regarding the possibility and effects of future adverse
change with respect to the related Mortgaged Property, to estimate and consider
(among other things) future expenses and to estimate and consider (among other
things) the timing of recoveries. In addition, the Master Servicer or the
Special Servicer may update or change its recoverability determination at any
time with respect to any P&I Advance, and the Master Servicer may obtain from
the Special Servicer any analysis, appraisals or market value estimates or other
information in the possession of the Special Servicer for purposes of
determining whether a P&I Advance is a Nonrecoverable P&I Advance.

          In addition, if (i) the Master Servicer reasonably believes, in
accordance with the Servicing Standard, that a P&I Advance with respect to any
Outside Serviced Trust Mortgage Loan or any successor REO Trust Mortgage Loan
with respect thereto constitutes or may, if made, constitute a Nonrecoverable
P&I Advance, and (ii) either (A) the Master Servicer has made a request for an
appraisal with respect to the related Mortgaged Property from the applicable
Outside Servicer and has not obtained, (x) within 15 Business Days of such
request, a response from the applicable Outside Servicer indicating that an
appraisal with respect to the related Mortgaged Property would be performed
within 60 days of the date of such response or has been performed within the
prior 12-month period (or such shorter period as the Master Servicer reasonably
believes, in accordance with the Servicing Standard, is necessary) preceding the
date of such request, and (y) within 60 days of the date of such response, a
copy of an appraisal report with respect to the related Mortgaged Property,
relating to an appraisal that has been performed within the 12-month period (or
such shorter period as the Master Servicer reasonably believes, in accordance
with the Servicing Standard, is necessary) preceding the date of such request by
the Master Servicer, that complies with the requirements for such an appraisal
under the terms of the related Outside Servicing Agreement or this Agreement, or
(B) the Master Servicer has made a request for an appraisal with respect to the
related Mortgaged Property from the applicable Outside Servicer and has been
advised by the applicable Outside Servicer that such an appraisal with respect
to the related Mortgaged Property will not be performed within the time periods
specified in clause (ii)(A) above, then the Master Servicer may have an
appraisal performed with respect


                                     -288-



to the related Mortgaged Property by an Independent Appraiser or other expert in
real estate matters, which appraisal shall take into account the factors
specified in Section 3.18, and the cost of which appraisal may be withdrawn from
general collections on deposit in the Pool Custodial Account. If, in connection
with the foregoing, it is necessary for the Master Servicer to obtain an
appraisal, the Master Servicer shall so notify the Special Servicer and consult
with the Special Servicer regarding such appraisal.

          If any of the Pari Passu Non-Trust Mortgage Loans is securitized as
part of a rated commercial mortgage securitization similar to the commercial
mortgage securitization contemplated by this Agreement, and if the Master
Servicer receives written notice that the primary party responsible for making
delinquency advances similar to P&I Advances hereunder with respect to such
other commercial mortgage securitization has determined, in accordance with the
requirements of the related Non-Trust Mortgage Loan Securitization Agreement,
that any such delinquency advance made or to be made with respect to such
securitized Pari Passu Non-Trust Mortgage Loan (or any successor REO Mortgage
Loan or comparable deemed mortgage loan with respect thereto) would not
ultimately be recoverable out of collections on such Pari Passu Non-Trust
Mortgage Loan (or such REO Mortgage Loan or comparable deemed mortgage loan),
then the Master Servicer shall deliver written notice to such effect to the
Trustee, any Fiscal Agent and the Depositor.

          In addition, if the Master Servicer has actual knowledge that any of
the Pari Passu Non-Trust Mortgage Loans is securitized as part of a rated
commercial mortgage securitization similar to the commercial mortgage
securitization contemplated by this Agreement, and if the Master Servicer
determines that any P&I Advance made or to be made with respect to the related
Combination Trust Mortgage Loan (or any successor REO Trust Mortgage Loan with
respect thereto) is or, if made, would be a Nonrecoverable P&I Advance, then the
Master Servicer shall, consistent with the related Co-Lender Agreement (if
applicable), notify, in writing, its counterpart under each such other
commercial mortgage securitization within one (1) Business Day of such
determination, which written notice shall be accompanied by the supporting
evidence for such determination. It will, consistent with the related Co-Lender
Agreement (if applicable), also notify, in writing, its counterpart under each
such other commercial mortgage securitization (within one (1) Business Day of
such determination) if it subsequently determines that P&I Advances made or to
be made with respect to the related Combination Trust Mortgage Loan (or any
successor REO Trust Mortgage Loan with respect thereto) are no longer
Nonrecoverable P&I Advances. Following a determination of nonrecoverability by
the Master Servicer in accordance with this paragraph or by another party
responsible for making delinquency advances similar to P&I Advances with respect
to a securitized Pari Passu Non-Trust Mortgage Loan (or any successor REO
Mortgage Loan or comparable deemed mortgage loan with respect thereto) in
accordance with the preceding paragraph, prior to the Master Servicer resuming
P&I Advances with respect to the related Combination Trust Mortgage Loan (or any
successor REO Trust Mortgage Loan with respect thereto), the Master Servicer
shall consult with its counterparts under the securitizations of any such Pari
Passu Non-Trust Mortgage Loans regarding whether circumstances with respect to
the subject mortgage loans have changed such that a proposed future P&I Advance
would not be a Nonrecoverable P&I Advance.

          (d) The Master Servicer, the Trustee and any Fiscal Agent shall each
be entitled to receive interest at the Reimbursement Rate in effect from time to
time, compounded annually, accrued on the amount of each P&I Advance made
thereby under this Section 4.03 (with its own funds) for so long as such P&I
Advance is outstanding; provided that if the grace period for the delinquent
Monthly


                                     -289-



Payment as to which a P&I Advance was made under this Section 4.03 has not
elapsed as of the time such P&I Advance was made, then the total interest so
accrued on such P&I Advance prior to the expiration of such grace period, shall
not exceed the amount of Default Charges, if any, Received by the Trust in
connection with the late payment of such delinquent Monthly Payment; and
provided, further, that, in no event shall interest so accrue on any P&I Advance
as to which the corresponding Late Collection was received by the Master
Servicer or a Sub-Servicer on its behalf as of the related Trust Master Servicer
Remittance Date. Interest so accrued on any P&I Advance made under this Section
4.03 shall be payable: (i) first, in accordance with Sections 3.05(a) and 3.26,
out of any Default Charges on deposit in the Pool Custodial Account that were
collected on or in respect of the particular Trust Mortgage Loan or REO Trust
Mortgage Loan as to which the P&I Advance relates (provided that such Default
Charges will only be applied to pay interest accrued on such P&I Advance through
the date that such Default Charges were received); and (ii) then, if and to the
extent that such Default Charges are insufficient to cover such interest, but
not before the related Advance is being reimbursed or has been reimbursed
pursuant to this Agreement, out of general collections on the Mortgage Pool on
deposit in the Pool Custodial Account; provided that, in the case of P&I
Advances with respect to an Outside Serviced Trust Mortgage Loan or any
successor REO Trust Mortgage Loan with respect thereto, the Master Servicer
shall, no less often than monthly, notify the related Outside Master Servicer of
the interest accruing on such P&I Advances in accordance with this Section
4.03(d) and, to the maximum extent permitted by the related Co-Lender Agreement,
prior to paying such interest on such P&I Advances out of general collections in
respect of the Mortgage Pool on deposit in the Pool Custodial Account, shall
seek payment for such interest on such P&I Advances from the related Outside
Master Servicer out of amounts otherwise payable with respect to the Outside
Serviced Loan Combination that includes such Outside Serviced Trust Mortgage
Loan or any successor REO Trust Mortgage Loan with respect thereto, to the
maximum extent permitted by, and out of amounts specified for such purpose
under, the related Co-Lender Agreement; and provided, further, that, if such P&I
Advance was made with respect to a Serviced Combination Trust Mortgage Loan or
any REO Trust Mortgage Loan with respect thereto, then such interest on such P&I
Advance shall first be payable out of amounts on deposit in the related Serviced
Loan Combination Custodial Account in accordance with, and to the extent
provided in, Section 3.05A. The Master Servicer shall, in accordance with
Section 3.05(a) and/or Section 3.05A, reimburse itself, the Trustee or any
Fiscal Agent, as applicable, for any outstanding P&I Advance made thereby under
this Section 4.03 as soon as practicable after funds available for such purpose
are deposited in the applicable Custodial Account. Notwithstanding the
foregoing, upon a determination that a previously made P&I Advance is a
Nonrecoverable P&I Advance, instead of obtaining reimbursement out of general
collections on the Mortgage Pool immediately, any of the Master Servicer, the
Trustee or any Fiscal Agent, as applicable, may, in its sole discretion, elect
to obtain reimbursement for such Nonrecoverable P&I Advance over a period of
time (not to exceed 12 months or such longer period of time as is approved in
writing by the Controlling Class Representative) and the unreimbursed portion of
such P&I Advance will accrue interest at the Reimbursement Rate in effect from
time to time. At any time after such a determination to obtain reimbursement
over time in accordance with the preceding sentence, the Master Servicer, the
Trustee or any Fiscal Agent, as applicable, may, in its sole discretion, decide
to obtain reimbursement immediately. The fact that a decision to recover such
Nonrecoverable P&I Advance over time, or not to do so, benefits some Classes of
Certificateholders to the detriment of other Classes shall not constitute a
violation of the Servicing Standard by the Master Servicer or a breach of any
fiduciary duty owed to the Certificateholders by the Trustee or any Fiscal
Agent, or a breach of any other contractual obligation owed to the
Certificateholders by any party to this Agreement.

          SECTION 4.04.  Allocations of Realized Losses and Additional Trust
                         Fund Expenses

          (a) On each Distribution Date, following the distributions to
Certificateholders to be made on such date pursuant to Section 4.01, the Trustee
shall determine the amount, if any, by which (i) the then aggregate of the Class
Principal Balances of all the Classes of Principal Balance Certificates
(exclusive of the Loan-Specific Certificates), exceeds (ii) the aggregate Stated
Principal Balance of the Mortgage Pool (net of the Uncertificated Principal
Balances of the STML Group B REMIC I Regular Interests) that will be outstanding
immediately following such Distribution Date. If such excess does exist, then
the respective Class Principal Balances of the various Classes of the Class B
Through T Certificates shall be reduced sequentially, in reverse alphabetic
order of the respective Class designations of such Classes of Certificates
(beginning with the Class T Certificates and ending with the Class B
Certificates), in each case until such excess is eliminated or the applicable
Class Principal Balance has been reduced to zero (whichever occurs first). If,
after the reduction to zero of the respective Class Principal Balances of all
the Classes of Class B Through T Certificates, the amount described in clause
(i) of the second preceding sentence (taking into account such reductions) still
exceeds the amount described in clause (ii) of the second preceding sentence,
then the respective Class Principal Balances of the various Classes of the Class
A Certificates shall be reduced sequentially as follows, in each case to zero if
necessary, until such remaining excess is eliminated: first, the Class Principal
Balance of the Class A-J Certificates shall be reduced; second, if and to the
extent necessary, the Class Principal Balance of the Class A-M Certificates
shall be reduced; and last, if and to the extent necessary, the respective Class
Principal Balances of the various Classes of the Senior Class A Certificates
shall be reduced, on a pro rata basis in accordance with the respective
outstanding Class Principal Balances thereof.

          On each Distribution Date, following the distributions to
Certificateholders to be made on such date pursuant to Section 4.01, the Trustee
shall determine the amount, if any, by which (i) the then aggregate of the Class
Principal Balances of the Class HAF Certificates, exceeds (ii) the aggregate
Uncertificated Principal Balance of the HAF STML Group B REMIC I Regular
Interests that will be outstanding immediately following such Distribution Date.
If such excess does exist, then the Class Principal Balances of the Class
HAF-11, Class HAF-10, Class HAF-9, Class HAF-8, Class HAF-7, HAF-6, Class HAF-5,
Class HAF-4, Class HAF-3, Class HAF-2 and Class HAF-1 Certificates shall be
reduced sequentially as among such Classes, in that order, in each case until
such excess or the related Class Principal Balance is reduced to zero (whichever
occurs first).

          On each Distribution Date, following the distributions to
Certificateholders to be made on such date pursuant to Section 4.01, the Trustee
shall determine the amount, if any, by which (i) the then aggregate of the Class
Principal Balances of the Class SBC Certificates, exceeds (ii) the
Uncertificated Principal Balance of REMIC I Regular Interest STUR-B that will be
outstanding immediately following such Distribution Date. If such excess does
exist, then the Class Principal Balances of the Class SBC-15, Class SBC-14,
Class SBC-13, Class SBC-12, Class SBC-11, Class SBC-10, Class SBC-9, Class
SBC-8, Class SBC-7, SBC-6, Class SBC-5, Class SBC-4, Class SBC-3, Class SBC-2
and Class SBC-1 Certificates shall be reduced sequentially as among such
Classes, in that order, in each case until such excess or the related Class
Principal Balance is reduced to zero (whichever occurs first).


                                     -291-



          Any and all such reductions in the Class Principal Balances of the
respective Classes of the Principal Balance Certificates pursuant to this
Section 4.04(a) shall be deemed to constitute allocations of Realized Losses and
Additional Trust Fund Expenses.

          (b) If the Class Principal Balance of any Class of Principal Balance
Certificates is reduced on any Distribution Date pursuant to Section 4.04(a),
then the Uncertificated Principal Balance of such Class' Corresponding REMIC II
Regular Interest (or, if applicable, the aggregate Uncertificated Principal
Balance of such Class' Corresponding REMIC II Regular Interests) shall be deemed
to have first been reduced on such Distribution Date by the exact same amount.
If a Class of Principal Balance Certificates has two or more Corresponding REMIC
II Regular Interests, then the respective Uncertificated Principal Balances of
such Corresponding REMIC II Regular Interests shall be reduced as contemplated
by the preceding sentence in the same sequential order that principal
distributions are deemed made on such Corresponding REMIC II Regular Interests
pursuant to Section 4.01(l), such that no reduction shall be made in the
Uncertificated Principal Balance of any such Corresponding REMIC II Regular
Interest pursuant to this Section 4.04(b) until the Uncertificated Principal
Balance of each other such Corresponding REMIC II Regular Interest, if any, with
an alphanumeric designation that ends in a lower number, has been reduced to
zero. Any and all such reductions in the Uncertificated Principal Balances of
the respective REMIC II Regular Interests shall be deemed to constitute
allocations of Realized Losses and Additional Trust Fund Expenses.

          (c) On each Distribution Date, following the deemed distributions to
be made in respect of the REMIC I Regular Interests pursuant to Section 4.01(m),
the Uncertificated Principal Balance of each REMIC I Regular Interest (after
taking account of such deemed distributions) shall be reduced, if and to the
extent necessary, to equal the Stated Principal Balance of the related Trust
Mortgage Loan or REO Trust Mortgage Loan (or, in the case of an STML Group B
REMIC I Regular Interest, to equal the excess, if any, of the Stated Principal
Balance of the related Split Trust Mortgage Loan or related Split REO Trust
Mortgage Loan, over the Uncertificated Principal Balance of the STML Group A
REMIC I Regular Interest that corresponds to the same Split Trust Mortgage Loan
or Split REO Trust Mortgage Loan), as applicable, that will be outstanding
immediately following such Distribution Date. Any and all such reductions in the
Uncertificated Principal Balances of the respective REMIC I Regular Interests
shall be deemed to constitute allocations of Realized Losses and Additional
Trust Fund Expenses.

          (d) On each Distribution Date, following any deemed distributions to
be made in respect of the Loan REMIC Regular Interests pursuant to Section
4.01(n), subject to Section 2.06(b), the Uncertificated Principal Balance of
each Loan REMIC Regular Interest (after taking account of such deemed
distributions) shall be reduced to equal the Stated Principal Balance of the
related Early Defeasance Trust Mortgage Loan or any successor REO Trust Mortgage
Loan with respect thereto, as the case may be, that will be outstanding
immediately following such Distribution Date. Any such reductions in the
Uncertificated Principal Balances of the respective Loan REMIC Regular Interests
shall be deemed to constitute allocations of Realized Losses and Additional
Trust Fund Expenses.

          SECTION 4.05.  Various Reinstatement Amounts.

          (a) On each Distribution Date, following the distributions to
Certificateholders to be made on such date pursuant to Section 4.01 or 9.01, as
applicable, the Trustee shall determine the amount, if any, by which (i) the
aggregate Stated Principal Balance of the Mortgage Pool (net of the


                                     -292-



Uncertificated Principal Balances of the STML Group B REMIC I Regular Interests)
that will be outstanding immediately following such Distribution Date, exceeds
(ii) the then aggregate of the Class Principal Balances of all the Classes of
Principal Balance Certificates (exclusive of the Loan-Specific Certificates). If
such an excess does exist, then the Trustee shall allocate the Total Principal
Reinstatement Amount, if any, for the subject Distribution Date as follows until
it is allocated in full: first, to all of the Classes of the Senior Class A
Certificates, up to, and on a pro rata basis in accordance with, the respective
Loss Reimbursement Amounts, if any, for such Classes of Senior Class A
Certificates with respect to such Distribution Date (minus any amounts
reimbursed in respect of such respective Loss Reimbursement Amounts on the
subject Distribution Date pursuant to Section 4.01(a)); second, to the Class A-M
Certificates, up to any Loss Reimbursement Amount for the Class A-M Certificates
with respect to such Distribution Date (minus any amount reimbursed in respect
of such Loss Reimbursement Amount on the subject Distribution Date pursuant to
Section 4.01(a)); third, to the Class A-J Certificates, up to any Loss
Reimbursement Amount for the Class A-J Certificates with respect to such
Distribution Date (minus any amount reimbursed in respect of such Loss
Reimbursement Amount on the subject Distribution Date pursuant to Section
4.01(a)); and then to the respective Classes of the Class B Through T
Certificates, sequentially as among such Classes in alphabetic order based on
the respective Class designations thereof (beginning with the Class B
Certificates and ending with the Class T Certificates), in each case up to any
Loss Reimbursement Amount for the applicable Class of Class B Through T
Certificates with respect to such Distribution Date (minus any amount reimbursed
in respect of such Loss Reimbursement Amount on the subject Distribution Date
pursuant to Section 4.01(b)). Any portion of the Total Principal Reinstatement
Amount for any Distribution Date that is allocated to a particular Class of
Principal Balance Certificates (exclusive of the Loan-Specific Certificates)
shall be: (i) referred to herein as the "Class Principal Reinstatement Amount"
in respect of such Class of Principal Balance Certificates for such Distribution
Date; and (ii) added to the Class Principal Balance of such Class of Principal
Balance Certificates on such Distribution Date. Notwithstanding anything to the
contrary contained herein, the parties hereby acknowledge that the reinstatement
of all or any portion of the Class Principal Balance of any Class of Principal
Balance Certificates (exclusive of the Loan-Specific Certificates) on any
Distribution Date shall be a result of the collection of Recovered Amounts,
Default Charges and/or Loss of Value Payments Received by the Trust during the
related Collection Period and the addition of such Recovered Amounts, Default
Charges and/or Loss of Value Payments to the Net Principal Distribution Amount
for purposes of calculating the Adjusted Net Principal Distribution Amount for
such Distribution Date.

          (b) In connection with the reinstatement of all or any portion of the
Class Principal Balance of any one or more Classes of Principal Balance
Certificates on any Distribution Date, pursuant to Section 4.05(a), the Trustee
shall calculate the amount of lost Distributable Certificate Interest that would
have accrued on the respective Classes of Regular Interest Certificates through
and including the end of the Interest Accrual Period for such Distribution Date
if no reduction to the Class Principal Balance of any Class of Principal Balance
Certificates, pursuant to Section 4.04(a), and no corresponding reduction to the
Uncertificated Principal Balance of any REMIC II Regular Interest(s), pursuant
to Section 4.04(b), had resulted on a prior Distribution Date from the
reimbursement out of general collections of principal on the Mortgage Pool of
the particular Advances (with interest thereon) that relate to the Recovered
Amounts associated with such reinstatement of outstanding principal on the
subject Distribution Date. Once determined, such lost Distributable Certificate
Interest in respect of any particular Class of Regular Interest Certificates
shall be reinstated and become due and payable on future Distribution Dates as
part of the unpaid Distributable Certificate Interest for such Class of Regular
Interest Certificates from prior Distribution Dates. All such reinstated
Distributable Certificate


                                     -293-



Interest in respect of any particular Class of Regular Interest Certificates
shall be treated the same as any other unpaid Distributable Certificate Interest
in respect of such Class of Regular Interest Certificates.

          (c) If the Class Principal Balance of any Class of Principal Balance
Certificates is increased on any Distribution Date pursuant to Section 4.05(a),
then the Uncertificated Principal Balance of such Class' Corresponding REMIC II
Regular Interest (or, if applicable, the aggregate Uncertificated Principal
Balance of such Class' Corresponding REMIC II Regular Interests) shall be deemed
to have first been increased on such Distribution Date by the exact same amount.
In circumstances where there are multiple Corresponding REMIC II Regular
Interests with respect to a Class of Principal Balance Certificates, the
increases in the respective Uncertificated Principal Balances of such
Corresponding REMIC II Regular Interests as contemplated by the prior sentence
shall be made in the reverse order that reductions are made to such
Uncertificated Principal Balances pursuant to Section 4.04(b), in each case up
to the amount of the Loss Reimbursement Amount with respect to the subject REMIC
II Regular Interest for such Distribution Date (minus any amount reimbursed in
respect of such Loss Reimbursement Amount on the subject Distribution Date
pursuant to Section 4.01(l)).

          (d) If any lost Distributable Certificate Interest is reinstated with
respect to any Class of Regular Interest Certificates on any Distribution Date
pursuant to Section 4.05(b), then a corresponding amount of Uncertificated
Distributable Interest shall be reinstated with respect to such Class'
Corresponding REMIC II Regular Interest(s) (or, in the case of the Interest-Only
Certificates, insofar as such lost Distributable Certificate Interest
corresponds to a particular REMIC III Component of such Class, a corresponding
amount of Uncertificated Distributable Interest shall be reinstated with respect
to such REMIC III Component's Corresponding REMIC II Regular Interest). In
circumstances where there are multiple Corresponding REMIC II Regular Interests
with respect to a Class of Principal Balance Certificates, the reinstatement of
such lost Uncertificated Distributable Interest with respect to such
Corresponding REMIC II Regular Interests as contemplated by the prior sentence
shall be effected taking into account the respective portions of such lost
Uncertificated Distributable Interest attributable to such Corresponding REMIC
II Regular Interests. Once reinstated, such lost Uncertificated Distributable
Interest in respect of any particular REMIC II Regular Interest shall become due
and payable on future Distribution Dates as part of the unpaid Uncertificated
Distributable Interest for such REMIC II Regular Interest from prior
Distribution Dates. All such reinstated Uncertificated Distributable Interest in
respect of any particular REMIC II Regular Interest shall be treated the same as
any other unpaid Uncertificated Distributable Interest in respect of such REMIC
II Regular Interest.

          SECTION 4.06.  Calculations.

          The Trustee shall, provided it receives the necessary information from
the Master Servicer and the Special Servicer, be responsible for performing all
calculations necessary in connection with the actual and deemed distributions
and allocations to be made pursuant to Section 4.01 and Article IX, the
allocations of Realized Losses and Additional Trust Fund Expenses to be made
pursuant to Section 4.04 and the reinstatements of principal balance and
interest to be made pursuant to Section 4.05. The Trustee shall calculate the
Available Distribution Amount, the Net Available Distribution Amount, the
respective portions of the Net Available Distribution Amount attributable to
each Loan Group, the Class HAF Available Distribution Amount and the Class SBC
Available Distribution Amount for each Distribution Date and shall allocate such
respective amounts among Certificateholders in accordance with this Agreement,
and the Trustee shall have no obligation to recompute, recalculate or verify any
information provided to it by the Special Servicer or Master Servicer. The
calculations by the


                                     -294-



Trustee of such amounts shall, in the absence of manifest error, be
presumptively deemed to be correct for all purposes hereunder.


                                     -295-



                                   ARTICLE V

                                THE CERTIFICATES

          SECTION 5.01.  The Certificates.

          (a) Subject to Sections 2.05(b) and 2.06(b), the Certificates will be
substantially in the respective forms attached hereto as Exhibits A-1, A-2, A-3,
A-4, A-5, A-6 and A-7; provided that any of the Certificates may be issued with
appropriate insertions, omissions, substitutions and variations, and may have
imprinted or otherwise reproduced thereon such legend or legends, not
inconsistent with the provisions of this Agreement, as may be required to comply
with any law or with rules or regulations pursuant thereto, or with the rules of
any securities market in which the Certificates are admitted to trading, or to
conform to general usage. The Certificates will be issuable in registered form
only; provided, however, that in accordance with Section 5.03, beneficial
ownership interests in the Regular Interest Certificates shall initially be held
and transferred through the book-entry facilities of the Depository. The Regular
Interest Certificates will be issuable only in denominations corresponding to
initial Certificate Principal Balances or initial Certificate Notional Amounts,
as the case may be, as of the Closing Date of $10,000 in the case of the Class
A-1, Class A-2, Class A-3, Class A-AB, Class A-4, Class A-1A, Class A-M, Class
A-J, Class B, Class C, Class D, Class E and Class F Certificates, $250,000 in
the case of the Interest-Only Certificates, and $250,000 in the case of the
remaining Regular Interest Certificates, and in each such case in integral
multiples of $1 in excess thereof. Subject to Sections 2.05(b) and 2.06(b), the
Class R-I, Class R-II, Class R-III, Class R-LR and Class V Certificates will be
issuable in denominations representing Percentage Interests in the applicable
Class of not less than 10%.

          (b) The Certificates shall be executed by manual or facsimile
signature on behalf of the Trustee by the Certificate Registrar hereunder by an
authorized signatory. Certificates bearing the manual or facsimile signatures of
individuals who were at any time the authorized officers or signatories of the
Certificate Registrar shall be entitled to all benefits under this Agreement,
subject to the following sentence, notwithstanding that such individuals or any
of them have ceased to hold such offices prior to the authentication and
delivery of such Certificates or did not hold such offices at the date of such
Certificates. No Certificate shall be entitled to any benefit under this
Agreement, or be valid for any purpose, however, unless there appears on such
Certificate a certificate of authentication substantially in the form provided
for herein executed by the Authenticating Agent by manual signature, and such
certificate of authentication upon any Certificate shall be conclusive evidence,
and the only evidence, that such Certificate has been duly authenticated and
delivered hereunder. All Certificates shall be dated the date of their
authentication.

          SECTION 5.02.  Registration of Transfer and Exchange of Certificates.

          (a) At all times during the term of this Agreement, there shall be
maintained at the office of the Certificate Registrar a Certificate Register in
which, subject to such reasonable regulations as the Certificate Registrar may
prescribe, the Certificate Registrar shall provide for the registration of
Certificates and of transfers and exchanges of Certificates as herein provided.
The Trustee is hereby initially appointed (and hereby agrees to act in
accordance with the terms hereof) as Certificate Registrar for the purpose of
registering Certificates and transfers and exchanges of Certificates as herein
provided. The offices of the Trustee responsible for its duties as initial
Certificate Register shall be located, as of


                                     -296-



the Closing Date, at 135 South LaSalle Street, Suite 1625, Chicago, Illinois
60603, Attention: Global Securities and Trust Services--LB-UBS Commercial
Mortgage Trust 2006-C4. The Certificate Registrar may appoint, by a written
instrument delivered to the Depositor, the Master Servicer, the Special Servicer
and (if the Trustee is not the Certificate Registrar) the Trustee, any other
bank or trust company to act as Certificate Registrar under such conditions as
the predecessor Certificate Registrar may prescribe, provided that the
predecessor Certificate Registrar shall not be relieved of any of its duties or
responsibilities hereunder by reason of such appointment. If the Trustee resigns
or is removed in accordance with the terms hereof, the successor trustee shall
immediately succeed to its duties as Certificate Registrar. The Depositor, the
Trustee (if it is no longer the Certificate Registrar), the Master Servicer and
the Special Servicer shall have the right to inspect the Certificate Register or
to obtain a copy thereof at all reasonable times, and to rely conclusively upon
a certificate of the Certificate Registrar as to the information set forth in
the Certificate Register.

          If three or more Holders make written request to the Trustee, and such
request states that such Holders desire to communicate with other Holders with
respect to their rights under this Agreement or under the Certificates and is
accompanied by a copy of the communication which such Holders propose to
transmit, then the Trustee shall, within 30 days after the receipt of such
request, afford (or cause any other Certificate Registrar to afford) the
requesting Holders access during normal business hours to the most recent list
of Certificateholders held by the Certificate Registrar.

          (b) No Transfer of any Non-Registered Certificate or interest therein
shall be made unless that Transfer is exempt from the registration and/or
qualification requirements of the Securities Act and any applicable state
securities laws, or is otherwise made in accordance with the Securities Act and
such state securities laws.

          If a Transfer of any Definitive Non-Registered Certificate is to be
made without registration under the Securities Act (other than in connection
with the initial issuance of the Non-Registered Certificates or a Transfer of
such Certificate by the Depositor, Lehman Brothers or any of their respective
Affiliates or, in the case of a Global Certificate for any Class of Book-Entry
Non-Registered Certificates, a Transfer thereof to a successor Depository or to
the applicable Certificate Owner(s) in accordance with Section 5.03), then the
Certificate Registrar shall refuse to register such Transfer unless it receives
(and, upon receipt, may conclusively rely upon) either: (i) a certificate from
the Certificateholder desiring to effect such Transfer substantially in the form
attached hereto as Exhibit F-1 and a certificate from such Certificateholder's
prospective Transferee substantially in the form attached hereto either as
Exhibit F-2A or, except in the case of a Residual Interest Certificate, as
Exhibit F-2B; or (ii) an Opinion of Counsel satisfactory to the Trustee to the
effect that the prospective Transferee is an Institutional Accredited Investor
or a Qualified Institutional Buyer (or, in the case of Residual Interest
Certificate, to the effect that the prospective Transferee is a Qualified
Institutional Buyer) and such Transfer may be made without registration under
the Securities Act (which Opinion of Counsel shall not be an expense of the
Trust Fund or of the Depositor, the Master Servicer, the Special Servicer, the
Tax Administrator, the Trustee, any Fiscal Agent or the Certificate Registrar in
their respective capacities as such), together with the written certification(s)
as to the facts surrounding such Transfer from the Certificateholder desiring to
effect such Transfer and/or such Certificateholder's prospective Transferee on
which such Opinion of Counsel is based. Residual Interest Certificates may only
be held by Qualified Institutional Buyers, and each other Definitive
Non-Registered Certificate may only be held by Qualified Institutional Buyers
and Institutional Accredited Investors.


                                     -297-



          No beneficial interest in the Rule 144A Global Certificate for any
Class of Book-Entry Non-Registered Certificates may be held by any Person that
is not a Qualified Institutional Buyer. If a Transfer of any interest in the
Rule 144A Global Certificate for any Class of Book-Entry Non-Registered
Certificates is to be made without registration under the Securities Act (other
than in connection with the initial issuance of the Book-Entry Non-Registered
Certificates or a Transfer of any interest therein by the Depositor, Lehman
Brothers or any of their respective Affiliates), then the Certificate Owner
desiring to effect such Transfer shall be required to obtain either (i) a
certificate from such Certificate Owner's prospective Transferee substantially
in the form attached hereto as Exhibit F-2C, or (ii) an Opinion of Counsel to
the effect that the prospective Transferee is a Qualified Institutional Buyer
and such Transfer may be made without registration under the Securities Act. If
any Transferee of an interest in the Rule 144A Global Certificate for any Class
of Book-Entry Non-Registered Certificates does not, in connection with the
subject Transfer, deliver to the Transferor the Opinion of Counsel or the
certification described in the preceding sentence, then such Transferee shall be
deemed to have represented and warranted that all the certifications set forth
in Exhibit F-2C hereto are, with respect to the subject Transfer, true and
correct. Further, as long as the Class T Certificates are Book-Entry
Certificates, any Certificate Owner desiring to effect a transfer of a Class T
Certificate or any interest therein may not sell or otherwise transfer that
Certificate or any interest therein unless it has provided the Depositor with
prior written notice of such transfer (together with a copy of the certificate
required pursuant to clause (i) above, executed by the proposed transferee).

          Notwithstanding the preceding paragraph, any interest in the Rule 144A
Global Certificate for a Class of Book-Entry Non-Registered Certificates may be
transferred to any Non-United States Securities Person who takes delivery in the
form of a beneficial interest in the Regulation S Global Certificate for such
Class of Certificates, provided that the Certificate Owner desiring to effect
such Transfer (i) complies with the requirements for Transfers of interests in
such Regulation S Global Certificate set forth in the following paragraph and
(ii) delivers or causes to be delivered to the Certificate Registrar and the
Trustee (A) a certificate from such Certificate Owner confirming its ownership
of the beneficial interests in the subject Class of Book-Entry Non-Registered
Certificates to be transferred, (B) a copy of the certificate to be obtained by
such Certificate Owner from its prospective Transferee in accordance with the
second sentence of the following paragraph and (C) such written orders and
instructions as are required under the applicable procedures of the Depository,
Clearstream and Euroclear to direct the Trustee, as transfer agent for the
Depository, to approve the debit of the account of a Depository Participant by a
denomination of interests in such Rule 144A Global Certificate, and approve the
credit of the account of a Depository Participant by a denomination of interests
in such Regulation S Global Certificate, that is equal to the denomination of
beneficial interests in the subject Class of Book-Entry Non-Registered
Certificates to be transferred. Upon delivery to the Certificate Registrar and
the Trustee of such certifications and such orders and instructions, the
Trustee, subject to and in accordance with the applicable procedures of the
Depository, shall reduce the denomination of the Rule 144A Global Certificate in
respect of the subject Class of Book-Entry Non-Registered Certificates, and
increase the denomination of the Regulation S Global Certificate for such Class
of Certificates, by the denomination of the beneficial interest in such Class of
Certificates specified in such orders and instructions.

          No beneficial interest in the Regulation S Global Certificate for any
Class of Book-Entry Non-Registered Certificates may be held by any Person that
is a United States Securities Person. Any Certificate Owner desiring to effect
any Transfer of a beneficial interest in the Regulation S Global Certificate for
any Class of Book-Entry Non-Registered Certificates shall be required to obtain
from


                                     -298-



such Certificate Owner's prospective Transferee a certificate substantially in
the form set forth in Exhibit F-2D hereto to the effect that such Transferee is
not a United States Securities Person. If any Transferee of an interest in the
Regulation S Global Certificate for any Class of Book-Entry Non-Registered
Certificates does not, in connection with the subject Transfer, deliver to the
Transferor the certification described in the preceding sentence, then such
Transferee shall be deemed to have represented and warranted that all the
certifications set forth in Exhibit F-2D hereto are, with respect to the subject
Transfer, true and correct.

          Notwithstanding the preceding paragraph, any interest in the
Regulation S Global Certificate for a Class of Book-Entry Non-Registered
Certificates may be transferred to any Qualified Institutional Buyer that takes
delivery in the form of a beneficial interest in the Rule 144A Global
Certificate for such Class of Certificates, provided that the Certificate Owner
desiring to effect such transfer (i) complies with the requirements for
Transfers of interests in such Rule 144A Global Certificate set forth in the
third paragraph of this Section 5.02(b) and (ii) delivers or causes to be
delivered to the Certificate Registrar and the Trustee (A) a certificate from
such Certificate Owner confirming its ownership of the beneficial interests in
the subject Class of Book-Entry Non-Registered Certificates to be transferred,
(B) a copy of the certificate or Opinion of Counsel to be obtained by such
Certificate Owner from its prospective Transferee in accordance with the second
sentence of the third paragraph of this Section 5.02(b) and (C) such written
orders and instructions as are required under the applicable procedures of the
Depository, Clearstream and Euroclear to direct the Trustee to debit the account
of a Depository Participant by a denomination of interests in such Regulation S
Global Certificate, and credit the account of a Depository Participant by a
denomination of interests in such Rule 144A Global Certificate, that is equal to
the denomination of beneficial interests in the subject Class of Book-Entry
Non-Registered Certificates to be transferred. Upon delivery to the Certificate
Registrar and the Trustee of such certification(s) and/or Opinion of Counsel and
such orders and instructions, the Trustee, subject to and in accordance with the
applicable procedures of the Depository, shall reduce the denomination of the
Regulation S Global Certificate in respect of the subject Class of Book-Entry
Non-Registered Certificates, and increase the denomination of the Rule 144A
Global Certificate for such Class of Certificates, by the denomination of the
beneficial interest in such Class of Certificates specified in such orders and
instructions.

          Also notwithstanding the foregoing, any interest in a Global
Certificate with respect to any Class of Book-Entry Non-Registered Certificates
may be transferred by any Certificate Owner holding such interest to any
Institutional Accredited Investor (other than a Qualified Institutional Buyer)
that takes delivery in the form of a Definitive Certificate of the same Class as
such Global Certificate upon delivery to the Certificate Registrar and the
Trustee of (i) such certifications and/or opinions as are contemplated by the
second paragraph of this Section 5.02(b) and (ii) such written orders and
instructions as are required under the applicable procedures of the Depository
to direct the Trustee to debit the account of a Depository Participant by the
denomination of the transferred interests in such Global Certificate. Upon
delivery to the Certificate Registrar and the Trustee of the certifications
and/or opinions contemplated by the second paragraph of this Section 5.02(b),
the Trustee, subject to and in accordance with the applicable procedures of the
Depository, shall reduce the denomination of the subject Global Certificate by
the denomination of the transferred interests in such Global Certificate, and
shall cause a Definitive Certificate of the same Class as such Global
Certificate, and in a denomination equal to the reduction in the denomination of
such Global Certificate, to be executed, authenticated and delivered in
accordance with this Agreement to the applicable Transferee.


                                     -299-



          None of the Depositor, the Trustee or the Certificate Registrar is
obligated to register or qualify any Class of Non-Registered Certificates under
the Securities Act or any other securities law or to take any action not
otherwise required under this Agreement to permit the Transfer of any
Non-Registered Certificate or interest therein without registration or
qualification. Any Certificateholder or Certificate Owner desiring to effect a
Transfer of any Non-Registered Certificate or interest therein shall, and does
hereby agree to, indemnify the Depositor, the Underwriters, the Trustee, any
Fiscal Agent, the Master Servicer, the Special Servicer, the Tax Administrator
and the Certificate Registrar against any liability that may result if such
Transfer is not exempt from the registration and/or qualification requirements
of the Securities Act and any applicable state securities laws or is not made in
accordance with such federal and state laws.

          (c) No Transfer of a Certificate or any interest therein shall be made
(i) to any employee benefit plan or other retirement arrangement, including
individual retirement accounts and annuities, Keogh plans and collective
investment funds and separate accounts in which such plans, accounts or
arrangements are invested, including insurance company general accounts, that is
subject to ERISA or the Code (each, a "Plan"), or (ii) to any Person who is
directly or indirectly purchasing such Certificate or interest therein on behalf
of, as named fiduciary of, as trustee of, or with assets of a Plan, if the
purchase and holding of such Certificate or interest therein by the prospective
Transferee would result in a violation of Section 406 or 407 of ERISA or Section
4975 of the Code or would result in the imposition of an excise tax under
Section 4975 of the Code. Except in connection with the initial issuance of the
Non-Registered Certificates or any Transfer of a Non-Registered Certificate or
any interest therein by the Depositor, Lehman Brothers or any of their
respective Affiliates or, in the case of a Global Certificate for any Class of
Book-Entry Non-Registered Certificates, any Transfer thereof to a successor
Depository or to the applicable Certificate Owner(s) in accordance with Section
5.03, the Certificate Registrar shall refuse to register the Transfer of a
Definitive Non-Registered Certificate unless it has received from the
prospective Transferee, and any Certificate Owner transferring an interest in a
Global Certificate for any Class of Book-Entry Non-Registered Certificates shall
be required to obtain from its prospective Transferee, one of the following: (i)
a certification to the effect that such prospective Transferee is not a Plan and
is not directly or indirectly purchasing such Certificate or interest therein on
behalf of, as named fiduciary of, as trustee of, or with assets of a Plan; or
(ii) alternatively, except in the case of a Residual Interest Certificate or, if
issued hereunder taking into account Section 2.05(b), a Class V Certificate, a
certification to the effect that the purchase and holding of such Certificate or
interest therein by such prospective Transferee is exempt from the prohibited
transaction provisions of Sections 406(a) and (b) and 407 of ERISA and the
excise taxes imposed on such prohibited transactions by Sections 4975(a) and (b)
of the Code, by reason of Sections I and III of Prohibited Transaction Class
Exemption 95-60; or (iii) alternatively, but only in the case of a
Non-Registered Certificate that is an Investment Grade Certificate (other than,
if applicable, a Residual Interest Certificate or, if issued hereunder taking
into account Section 2.05(b), a Class V Certificate) that is being acquired by
or on behalf of a Plan in reliance on the Prohibited Transaction Exemption, a
certification to the effect that such Plan (X) is an accredited investor as
defined in Rule 501(a)(1) of Regulation D of the Securities Act, (Y) is not
sponsored (within the meaning of Section 3(16)(B) of ERISA) by the Trustee, the
Depositor, any Mortgage Loan Seller, the Master Servicer, the Special Servicer,
any Sub-Servicer, any Person responsible for servicing an Outside Serviced Trust
Mortgage Loan or administering an Outside Administered REO Property, any
Exemption-Favored Party or any Mortgagor with respect to Trust Mortgage Loans
constituting more than 5% of the aggregate unamortized principal balance of all
the Trust Mortgage Loans determined as of the Closing Date, or by any Affiliate
of such Person, and (Z) agrees that it will obtain from each of its Transferees
that are Plans


                                     -300-



a written representation that such Transferee, if a Plan, satisfied the
requirements of the immediately preceding clauses (iii)(X) and (iii)(Y),
together with a written agreement that such Transferee will obtain from each of
its Transferees that are Plans a similar written representation regarding
satisfaction of the requirements of the immediately preceding clauses (iii)(X)
and (iii)(Y); or (iv) alternatively, a certification of facts and an Opinion of
Counsel which otherwise establish to the reasonable satisfaction of the Trustee
or such Certificate Owner, as the case may be, that such Transfer will not
result in a violation of Section 406 or 407 of ERISA or Section 4975 of the Code
or result in the imposition of an excise tax under Section 4975 of the Code. It
is hereby acknowledged that the forms of certification attached hereto as
Exhibit G-1 (in the case of Definitive Non-Registered Certificates) and Exhibit
G-2 (in the case of ownership interests in Book-Entry Non-Registered
Certificates) are acceptable for purposes of the preceding sentence. If any
Transferee of a Certificate (including a Registered Certificate) or any interest
therein does not, in connection with the subject Transfer, deliver to the
Certificate Registrar (in the case of a Definitive Certificate) or the
Transferor (in the case of ownership interests in a Book-Entry Certificate) any
certification and/or Opinion of Counsel contemplated by the second preceding
sentence, then such Transferee shall be deemed to have represented and warranted
that either: (i) such Transferee is not a Plan and is not directly or indirectly
purchasing such Certificate or interest therein on behalf of, as named fiduciary
of, as trustee of, or with assets of a Plan; or (ii) the purchase and holding of
such Certificate or interest therein by such Transferee is exempt from the
prohibited transaction provisions of Sections 406(a) and (b) and 407 of ERISA
and the excise taxes imposed on such prohibited transactions by Sections 4975(a)
and (b) of the Code.

          (d) (i) Each Person who has or who acquires any Ownership Interest in
a Residual Interest Certificate shall be deemed by the acceptance or acquisition
of such Ownership Interest to have agreed to be bound by the following
provisions and to have irrevocably authorized the Trustee under clause (ii)(A)
below to deliver payments to a Person other than such Person and to have
irrevocably authorized the Trustee under clause (ii)(B) below to negotiate the
terms of any mandatory disposition and to execute all instruments of Transfer
and to do all other things necessary in connection with any such disposition.
The rights of each Person acquiring any Ownership Interest in a Residual
Interest Certificate are expressly subject to the following provisions:

               (A)  Each Person holding or acquiring any Ownership Interest in a
                    Residual Interest Certificate shall be a Permitted
                    Transferee and shall promptly notify the Tax Administrator
                    and the Trustee of any change or impending change in its
                    status as a Permitted Transferee.

               (B)  In connection with any proposed Transfer of any Ownership
                    Interest in a Residual Interest Certificate, the Certificate
                    Registrar shall require delivery to it, and shall not
                    register the Transfer of any Residual Interest Certificate
                    until its receipt, of an affidavit and agreement
                    substantially in the form attached hereto as Exhibit H-1 (a
                    "Transfer Affidavit and Agreement"), from the proposed
                    Transferee, representing and warranting, among other things,
                    that such Transferee is a Permitted Transferee, that it is
                    not acquiring its Ownership Interest in the Residual
                    Interest Certificate that is the subject of the proposed
                    Transfer as a nominee, trustee or agent for any Person that
                    is not a Permitted Transferee, that for so long as it
                    retains its Ownership Interest in a Residual Interest
                    Certificate it will


                                     -301-



                    endeavor to remain a Permitted Transferee, and that it has
                    reviewed the provisions of this Section 5.02(d) and agrees
                    to be bound by them.

               (C)  Notwithstanding the delivery of a Transfer Affidavit and
                    Agreement by a proposed Transferee under clause (B) above,
                    if a Responsible Officer of either the Trustee or the
                    Certificate Registrar has actual knowledge that the proposed
                    Transferee is not a Permitted Transferee, no Transfer of an
                    Ownership Interest in a Residual Interest Certificate to
                    such proposed Transferee shall be effected.

               (D)  Each Person holding or acquiring any Ownership Interest in a
                    Residual Interest Certificate shall agree (1) to require a
                    Transfer Affidavit and Agreement from any prospective
                    Transferee to whom such Person attempts to Transfer its
                    Ownership Interest in such Residual Interest Certificate and
                    (2) not to Transfer its Ownership Interest in such Residual
                    Interest Certificate unless it provides to the Certificate
                    Registrar a certificate substantially in the form attached
                    hereto as Exhibit H-2 stating that, among other things, it
                    has no actual knowledge that such prospective Transferee is
                    not a Permitted Transferee.

               (E)  Each Person holding or acquiring an Ownership Interest in a
                    Residual Interest Certificate, by purchasing such Ownership
                    Interest, agrees to give the Tax Administrator and the
                    Trustee written notice that it is a "pass-through interest
                    holder" within the meaning of temporary Treasury regulations
                    section 1.67-3T(a)(2)(i)(A) immediately upon acquiring an
                    Ownership Interest in a Residual Interest Certificate, if it
                    is, or is holding an Ownership Interest in a Residual
                    Interest Certificate on behalf of, a "pass-through interest
                    holder".

               (ii) (A) If any purported Transferee shall become a Holder of a
     Residual Interest Certificate in violation of the provisions of this
     Section 5.02(d), then the last preceding Holder of such Residual Interest
     Certificate that was in compliance with the provisions of this Section
     5.02(d) shall be restored, to the extent permitted by law, to all rights as
     Holder thereof retroactive to the date of registration of such Transfer of
     such Residual Interest Certificate. None of the Depositor, the Trustee or
     the Certificate Registrar shall be under any liability to any Person for
     any registration of Transfer of a Residual Interest Certificate that is in
     fact not permitted by this Section 5.02(d) or for making any payments due
     on such Certificate to the Holder thereof or for taking any other action
     with respect to such Holder under the provisions of this Agreement.

          (B)  If any purported Transferee shall become a Holder of a Residual
               Interest Certificate in violation of the restrictions in this
               Section 5.02(d), then, to the extent that retroactive restoration
               of the rights of the preceding Holder of such Residual Interest
               Certificate as described in clause (ii)(A) above shall be
               invalid, illegal or unenforceable, the Trustee shall have the
               right but not the obligation, to cause the Transfer of such
               Residual Interest Certificate to a Permitted Transferee selected
               by the Trustee on such terms as the Trustee may choose, and the
               Trustee


                                     -302-



               shall not be liable to any Person having an Ownership Interest in
               such Residual Interest Certificate as a result of the Trustee's
               exercise of such discretion. Such purported Transferee shall
               promptly endorse and deliver such Residual Interest Certificate
               in accordance with the instructions of the Trustee. Such
               Permitted Transferee may be the Trustee itself or any Affiliate
               of the Trustee.

               (iii) The Tax Administrator shall make available to the IRS and
     to those Persons specified by the REMIC Provisions all information
     furnished to it by the other parties hereto necessary to compute any tax
     imposed (A) as a result of the Transfer of an Ownership Interest in a
     Residual Interest Certificate to any Person who is a Disqualified
     Organization, including the information described in Treasury regulations
     sections 1.860D-1(b)(5) and 1.860E-2(a)(5) with respect to the "excess
     inclusions" of such Residual Interest Certificate and (B) as a result of
     any regulated investment company, real estate investment trust, common
     trust fund, partnership, trust, estate or organization described in Section
     1381 of the Code that holds an Ownership Interest in a Residual Interest
     Certificate having as among its record holders at any time any Person which
     is a Disqualified Organization, and each of the other parties hereto shall
     furnish to the Tax Administrator all information in its possession
     necessary for the Tax Administrator to discharge such obligation. The
     Person holding such Ownership Interest shall be responsible for the
     reasonable compensation of the Tax Administrator for providing information
     thereto pursuant to this subsection (d)(iii) and Section 10.01(h)(i).

               (iv) The provisions of this Section 5.02(d) set forth prior to
     this clause (iv) may be modified, added to or eliminated, provided that
     there shall have been delivered to the Trustee and the Tax Administrator
     the following:

               (A)  written confirmation from each Rating Agency to the effect
                    that the modification of, addition to or elimination of such
                    provisions will not cause an Adverse Rating Event with
                    respect to any Class of Certificates; and

               (B)  an Opinion of Counsel, in form and substance satisfactory to
                    the Trustee and the Tax Administrator, obtained at the
                    expense of the party seeking such modification of, addition
                    to or elimination of such provisions (but in no event at the
                    expense of the Trustee, the Tax Administrator or the Trust),
                    to the effect that doing so will not (1) cause any REMIC
                    Pool to cease to qualify as a REMIC or be subject to an
                    entity-level tax caused by the Transfer of any Residual
                    Interest Certificate to a Person which is not a Permitted
                    Transferee or (2) cause a Person other than the prospective
                    Transferee to be subject to a REMIC-related tax caused by
                    the Transfer of a Residual Interest Certificate to a Person
                    that is not a Permitted Transferee.

          (e) If a Person is acquiring any Non-Registered Certificate or
interest therein as a fiduciary or agent for one or more accounts, such Person
shall be required to deliver to the Certificate Registrar (or, in the case of an
interest in a Book-Entry Non-Registered Certificate, to the Certificate Owner
that is transferring such interest) a certification to the effect that, and such
other evidence as may be reasonably required by the Trustee (or such Certificate
Owner) to confirm that, it has (i) sole


                                     -303-



investment discretion with respect to each such account and (ii) full power to
make the applicable foregoing acknowledgments, representations, warranties,
certifications and agreements with respect to each such account as set forth in
subsections (b), (c) and/or (d), as appropriate, of this Section 5.02.

          (f) Subject to the preceding provisions of this Section 5.02, upon
surrender for registration of transfer of any Certificate at the offices of the
Certificate Registrar maintained for such purpose, the Certificate Registrar
shall execute and the Authenticating Agent shall authenticate and deliver, in
the name of the designated transferee or transferees, one or more new
Certificates of the same Class evidencing a like aggregate Percentage Interest
in such Class.

          (g) At the option of any Holder, its Certificates may be exchanged for
other Certificates of authorized denominations of the same Class evidencing a
like aggregate Percentage Interest in such Class upon surrender of the
Certificates to be exchanged at the offices of the Certificate Registrar
maintained for such purpose. Whenever any Certificates are so surrendered for
exchange, the Certificate Registrar shall execute and the Authenticating Agent
shall authenticate and deliver the Certificates which the Certificateholder
making the exchange is entitled to receive.

          (h) Every Certificate presented or surrendered for transfer or
exchange shall (if so required by the Certificate Registrar) be duly endorsed
by, or be accompanied by a written instrument of transfer in the form
satisfactory to the Certificate Registrar duly executed by, the Holder thereof
or his attorney duly authorized in writing.

          (i) No service charge shall be imposed for any transfer or exchange of
Certificates, but the Trustee or Certificate Registrar may require payment of a
sum sufficient to cover any tax or other governmental charge that may be imposed
in connection with any transfer or exchange of Certificates.

          (j) All Certificates surrendered for transfer and exchange shall be
physically canceled by the Certificate Registrar, and the Certificate Registrar
shall dispose of such canceled Certificates in accordance with its standard
procedures.

          SECTION 5.03.  Book-Entry Certificates.

          (a) Each Class of Regular Interest Certificates shall initially be
issued as one or more Certificates registered in the name of the Depository or
its nominee and, except as provided in Section 5.02(b) and Section 5.03(c), a
Transfer of such Certificates may not be registered by the Certificate Registrar
unless such Transfer is to a successor Depository that agrees to hold such
Certificates for the respective Certificate Owners with Ownership Interests
therein. Such Certificate Owners shall hold and Transfer their respective
Ownership Interests in and to such Certificates through the book-entry
facilities of the Depository and, except as provided in Section 5.02(b) and
Section 5.03(c), shall not be entitled to definitive, fully registered
Certificates ("Definitive Certificates") in respect of such Ownership Interests.
The Class X, Class G, Class H, Class J, Class K, Class L, Class M, Class N,
Class P, Class Q, Class S and Class T Certificates and the Class HAF and Class
SBC Certificates initially sold to Qualified Institutional Buyers in reliance on
Rule 144A or in reliance on another exemption from the registration requirements
of the Securities Act shall, in the case of each such Class, be represented by
the Rule 144A Global Certificate for such Class, which shall be deposited with
the Trustee as custodian for the Depository and registered in the name of Cede &
Co. as nominee of the Depository. The Class X, Class G, Class H, Class J, Class
K, Class L, Class M, Class N, Class P, Class Q, Class S, Class T, Class HAF and
Class SBC Certificates initially sold in offshore transactions in reliance on
Regulation S shall, in the


                                     -304-



case of each such Class, be represented by the Regulation S Global Certificate
for such Class, which shall be deposited with the Trustee as custodian for the
Depository and registered in the name of Cede & Co. as nominee of the
Depository. All Transfers by Certificate Owners of their respective Ownership
Interests in the Book-Entry Certificates shall be made in accordance with the
procedures established by the Depository Participant or brokerage firm
representing each such Certificate Owner. Each Depository Participant shall only
transfer the Ownership Interests in the Book-Entry Certificates of Certificate
Owners it represents or of brokerage firms for which it acts as agent in
accordance with the Depository's normal procedures. Each Certificate Owner is
deemed, by virtue of its acquisition of an Ownership Interest in the applicable
Class of Book-Entry Certificates, to agree to comply with the transfer
requirements provided for in Section 5.02.

          (b) The Trustee, the Master Servicer, the Special Servicer, the
Depositor and the Certificate Registrar may for all purposes, including the
making of payments due on the Book-Entry Certificates, deal with the Depository
as the authorized representative of the Certificate Owners with respect to such
Certificates for the purposes of exercising the rights of Certificateholders
hereunder. The rights of Certificate Owners with respect to the Book-Entry
Certificates shall be limited to those established by law and agreements between
such Certificate Owners and the Depository Participants and brokerage firms
representing such Certificate Owners. Multiple requests and directions from, and
votes of, the Depository as Holder of the Book-Entry Certificates with respect
to any particular matter shall not be deemed inconsistent if they are made with
respect to different Certificate Owners. The Trustee may establish a reasonable
record date in connection with solicitations of consents from or voting by
Certificateholders and shall give notice to the Depository of such record date.

          (c) If (i)(A) the Depositor advises the Trustee and the Certificate
Registrar in writing that the Depository is no longer willing or able to
properly discharge its responsibilities with respect to a Class of the
Book-Entry Certificates, and (B) the Depositor is unable to locate a qualified
successor, or (ii) the Depositor notifies the Depository of its intent to
terminate the book-entry system through the Depository with respect to a Class
of Book-Entry Certificates and (in the event applicable law and/or the
Depository's procedures require that the Depository Participants holding
Ownership Interests in such Class of Book-Entry Certificates submit a withdrawal
request to the Depository in order to so terminate the book-entry system) the
Depositor additionally notifies those Depository Participants and those
Depository Participants submit a withdrawal request with respect to such
termination, then the Certificate Registrar shall notify all affected
Certificate Owners, through the Depository, of the occurrence of any such event
and of the availability of Definitive Certificates to such Certificate Owners
requesting the same.

          Upon surrender to the Certificate Registrar of the Book-Entry
Certificates of any Class thereof by the Depository, accompanied by registration
instructions from the Depository for registration of transfer, the Certificate
Registrar shall execute, and the Authenticating Agent shall authenticate and
deliver, the Definitive Certificates in respect of such Class to the Certificate
Owners identified in such instructions. None of the Depositor, the Master
Servicer, the Special Servicer, the Trustee or the Certificate Registrar shall
be liable for any delay in delivery of such instructions, and each of them may
conclusively rely on, and shall be protected in relying on, such instructions.
Upon the issuance of Definitive Certificates for purposes of evidencing
ownership of any Class of Registered Certificates, the registered holders of
such Definitive Certificates shall be recognized as Certificateholders hereunder
and, accordingly, shall be entitled directly to receive payments on, to exercise
Voting Rights with respect to, and to transfer and exchange such Definitive
Certificates.


                                     -305-



          (d) Notwithstanding any other provisions contained herein, neither the
Trustee nor the Certificate Registrar shall have any responsibility whatsoever
to monitor or restrict the Transfer of ownership interests in any Certificate
(including but not limited to any Non-Registered Certificate or any Subordinate
Certificate) which interests are transferable through the book-entry facilities
of the Depository.

          SECTION 5.04.  Mutilated, Destroyed, Lost or Stolen Certificates.

          If (i) any mutilated Certificate is surrendered to the Certificate
Registrar, or the Certificate Registrar receives evidence to its satisfaction of
the destruction, loss or theft of any Certificate, and (ii) there is delivered
to the Trustee and the Certificate Registrar such security or indemnity as may
be reasonably required by them to save each of them harmless, then, in the
absence of actual notice to the Trustee or the Certificate Registrar that such
Certificate has been acquired by a bona fide purchaser, the Certificate
Registrar shall execute and the Authenticating Agent shall authenticate and
deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or
stolen Certificate, a new Certificate of the same Class and like Percentage
Interest. Upon the issuance of any new Certificate under this section, the
Trustee and the Certificate Registrar may require the payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
relation thereto and any other expenses (including the fees and expenses of the
Trustee and the Certificate Registrar) connected therewith. Any replacement
Certificate issued pursuant to this section shall constitute complete and
indefeasible evidence of ownership in the applicable REMIC Pool or the Grantor
Trust (if created hereunder taking into account Section 2.05(b)), as applicable,
as if originally issued, whether or not the lost, stolen or destroyed
Certificate shall be found at any time.

          SECTION 5.05.  Persons Deemed Owners.

          Prior to due presentment for registration of transfer, the Depositor,
the Master Servicer, the Special Servicer, the Trustee, the Certificate
Registrar and any agent of any of them may treat the Person in whose name any
Certificate is registered as the owner of such Certificate for the purpose of
receiving distributions pursuant to Section 4.01 and for all other purposes
whatsoever and none of the Depositor, the Master Servicer, the Special Servicer,
the Trustee, the Certificate Registrar or any agent of any of them shall be
affected by notice to the contrary.

                                   ARTICLE VI

            THE DEPOSITOR, THE MASTER SERVICER, THE SPECIAL SERVICER
                    AND THE CONTROLLING CLASS REPRESENTATIVE

          SECTION 6.01.  Liability of Depositor, Master Servicer and Special
                         Servicer.

          The Depositor, the Master Servicer and the Special Servicer shall be
liable in accordance herewith only to the extent of the respective obligations
specifically imposed upon and undertaken by the Depositor, the Master Servicer
and the Special Servicer herein.

          SECTION 6.02.  Continued Qualification and Compliance of Master
                         Servicer; Merger, Consolidation or Conversion of
                         Depositor, Master Servicer or Special Servicer.

          Subject to the following paragraph, the Depositor, the Master Servicer
and the Special Servicer shall each keep in full effect its existence, rights
and franchises as a legal entity under the laws of the jurisdiction of its
organization, and each will obtain and preserve its qualification to do business
as a foreign entity in, and will otherwise remain in compliance with the laws
of, each jurisdiction in which such qualification and compliance is or shall be
necessary to protect the validity and enforceability of this Agreement, the
Certificates or any of the Mortgage Loans and to perform its respective duties
under this Agreement.

          Each of the Depositor, the Master Servicer and the Special Servicer
may be merged or consolidated with or into any Person, or transfer all or
substantially all of its assets (which, in the case of the Master Servicer or
the Special Servicer, may be limited to all or substantially all of its assets
related to commercial mortgage loan servicing) to any Person, in which case any
Person resulting from any merger or consolidation to which the Depositor, the
Master Servicer or the Special Servicer shall be a party, or any Person
succeeding to the business (which, in the case of the Master Servicer or the
Special Servicer, may be limited to the commercial mortgage loan servicing
business) of the Depositor, the Master Servicer or the Special Servicer, shall
be the successor of the Depositor, the Master Servicer or the Special Servicer,
as the case may be, hereunder, without the execution or filing of any paper or
any further act on the part of any of the parties hereto, anything herein to the
contrary notwithstanding; provided, however, that no successor or surviving
Person shall succeed to the rights of the Master Servicer or the Special
Servicer unless (i) as confirmed (at the expense of such successor or surviving
Person) in writing by each of the Rating Agencies (and, if any Specially
Designated Non-Trust Mortgaged Loan Securities are rated thereby, Fitch), such
succession will not result in an Adverse Rating Event with respect to any Class
of Certificates or any class of Specially Designated Non-Trust Mortgage Loan
Securities rated by such rating agency, and (ii) such successor or surviving
Person makes the applicable representations and warranties set forth in Section
3.23 (in the case of a successor or surviving Person to the Master Servicer) or
Section 3.24 (in the case of a successor or surviving Person to the Special
Servicer), as applicable. The successor or surviving Person shall be responsible
for the cost of obtaining the rating confirmations contemplated by clause (i) of
the proviso to the preceding sentence.


                                     -307-



          SECTION 6.03.  Limitation on Liability of Depositor, Master Servicer
                         and Special Servicer.

          None of the Depositor, the Master Servicer or the Special Servicer
shall be under any liability to the Trust Fund, the Trustee, the
Certificateholders or the Serviced Non-Trust Mortgage Loan Noteholders for any
action taken, or not taken, in good faith pursuant to this Agreement, or for
errors in judgment; provided, however, that this provision shall not protect the
Depositor, the Master Servicer or the Special Servicer against any liability to
the Trust Fund, the Trustee, the Certificateholders or the Serviced Non-Trust
Mortgage Loan Noteholders for the breach of a representation or warranty made
herein by such party, or against any expense or liability specifically required
to be borne by such party without right of reimbursement pursuant to the terms
hereof, or against any liability which would otherwise be imposed by reason of
willful misfeasance, bad faith or negligence in the performance of its
obligations or duties hereunder or negligent disregard of such obligations or
duties. The Depositor, the Master Servicer, the Special Servicer and any
director, manager, member, officer, employee or agent of the Depositor, the
Master Servicer or the Special Servicer may rely in good faith on any document
of any kind which, prima facie, is properly executed and submitted by any Person
respecting any matters arising hereunder. The Depositor, the Master Servicer,
the Special Servicer and any director, manager, member, officer, employee or
agent of the Depositor, the Master Servicer or the Special Servicer shall be
indemnified and held harmless by the Trust Fund out of the Pool Custodial
Account against any loss, liability or reasonable expense (including reasonable
legal fees and expenses) incurred in connection with (a) any legal action or
claim relating to this Agreement or the Certificates (including in connection
with the dissemination of information and reports as contemplated by this
Agreement) or (b) any mediation and/or arbitration, pursuant to Section 2.03(i)
hereof or Section 5(i) of the UBS/Depositor Mortgage Loan Purchase Agreement,
relating to this Agreement or the Certificates, other than, in any such case,
any such loss, liability or expense: (i) specifically required to be borne by
the party seeking indemnification, without right of reimbursement pursuant to
the terms hereof; (ii) which constitutes a Servicing Advance that is otherwise
reimbursable hereunder; (iii) incurred in connection with any legal action,
claim, mediation or arbitration against the party seeking indemnification,
resulting from any breach on the part of that party of a representation or
warranty made herein; or (iv) incurred in connection with any legal action,
claim, mediation or arbitration against the party seeking indemnification,
resulting from any willful misfeasance, bad faith or negligence on the part of
that party in the performance of its obligations or duties hereunder or
negligent disregard of such obligations or duties; provided that, if a Serviced
Loan Combination is involved, such indemnity shall be payable out of the related
Loan Combination Custodial Account pursuant to Section 3.05A and, if and to the
extent not solely attributable to one or more Serviced Non-Trust Mortgage Loans
(or any successor REO Mortgage Loan(s) with respect thereto) included in such
Serviced Loan Combination, shall also be payable out of the Pool Custodial
Account if amounts on deposit in the related Loan Combination Custodial
Account(s) are insufficient therefor; and provided, further, that in making a
determination as to whether any such indemnity is solely attributable to one or
more Serviced Non-Trust Mortgage Loans (or any successor REO Mortgage Loan(s)
with respect thereto), the fact that any related legal action was instituted by
or against a related Serviced Non-Trust Mortgage Loan Noteholder shall not
create a presumption that such indemnity is solely attributable thereto. None of
the Depositor, the Master Servicer or the Special Servicer shall be under any
obligation to appear in, prosecute or defend any legal action, mediation or
arbitration, unless such action, mediation or arbitration, as the case may be,
is related to its respective duties under this Agreement and either (i) it is
specifically required hereunder to bear the costs of such action, mediation or
arbitration, as the case may be, or (ii) such action, mediation or arbitration,
as the case may be, will not, in its reasonable and good faith judgment, involve
it in any


                                     -308-



ultimate expense or liability for which it would not be reimbursed hereunder.
Notwithstanding the foregoing, subject to Section 2.03(i) of this Agreement and
Section 5(i) of the UBS/Depositor Mortgage Loan Purchase Agreement, the
Depositor, the Master Servicer or the Special Servicer may in its discretion
undertake any legal action which it may deem necessary or desirable with respect
to the enforcement and/or protection of the rights and duties of the parties
hereto and the interests of the Certificateholders (or, if a Serviced Loan
Combination is affected, the rights of the Certificateholders and the related
Serviced Non-Trust Mortgage Loan Noteholder(s) (as a collective whole)). In such
event, the legal expenses and costs of such action, and any liability resulting
therefrom, shall be expenses, costs and liabilities of the Trust Fund, and the
Depositor, the Master Servicer and the Special Servicer shall be entitled to be
reimbursed therefor from the Pool Custodial Account as provided in Section
3.05(a); provided, however, that if and to the extent a Serviced Loan
Combination and/or a Serviced Non-Trust Mortgage Loan Noteholder is involved,
such expenses, costs and liabilities shall be payable out of the related Loan
Combination Custodial Account pursuant to Section 3.05A and, if and to the
extent attributable to one or more Trust Mortgage Loans and/or REO Trust
Mortgage Loans, shall also be payable out of the Pool Custodial Account if
amounts on deposit in the related Loan Combination Custodial Account are
insufficient therefor. In no event shall the Master Servicer or the Special
Servicer be liable or responsible for any action taken or omitted to be taken by
the other of them (unless they are the same Person or Affiliates) or for any
action taken or omitted to be taken by the Depositor, the Trustee, any
Certificateholder or any Serviced Non-Trust Mortgage Loan Noteholder (unless
they are the same Person or Affiliates).

          SECTION 6.04.  Resignation of Master Servicer and the Special
                         Servicer.

          (a) The Master Servicer and, subject to Section 6.09, the Special
Servicer may each resign from the obligations and duties hereby imposed on it,
upon a determination that its duties hereunder are no longer permissible under
applicable law or are in material conflict by reason of applicable law with any
other activities carried on by it (the other activities of the Master Servicer
or the Special Servicer, as the case may be, so causing such a conflict being of
a type and nature carried on by the Master Servicer or the Special Servicer, as
the case may be, at the date of this Agreement). Any such determination
requiring the resignation of the Master Servicer or the Special Servicer, as
applicable, shall be evidenced by an Opinion of Counsel to such effect which
shall be delivered to the Trustee. Unless applicable law requires the Master
Servicer's or Special Servicer's resignation to be effective immediately, and
the Opinion of Counsel delivered pursuant to the prior sentence so states, no
such resignation shall become effective until the Trustee or other successor
shall have assumed the responsibilities and obligations of the resigning party
in accordance with Section 6.09 or Section 7.02 hereof. The Master Servicer and,
subject to the rights of the Controlling Class under Section 6.09 to appoint a
successor special servicer, the Special Servicer shall each have the right to
resign at any other time, provided that (i) a willing successor thereto
reasonably acceptable to the Depositor has been found (provided that if the
Depositor has not responded to a request for consent to a successor within 15
days, such successor shall be deemed approved thereby), (ii) each Rating Agency
confirms in writing (at the expense of the resigning party) that the resignation
and the successor's appointment will not result in an Adverse Rating Event with
respect to any Class of Certificates rated by such Rating Agency, (iii) the
resigning party pays all costs and expenses in connection with such resignation
and the resulting transfer of servicing, and (iv) the successor accepts
appointment prior to the effectiveness of such resignation and agrees in writing
to be bound by the terms and conditions of this Agreement. Neither the Master
Servicer nor the Special Servicer shall be permitted to resign except as
contemplated above in this Section 6.04(a).


                                     -309-



          (b) Consistent with Section 6.04(a), neither the Master Servicer nor
the Special Servicer shall, except as expressly provided herein, assign or
transfer any of its rights, benefits or privileges hereunder to any other Person
or, except as provided in Sections 3.22, 4.07 and 7.01(d), delegate to or
subcontract with, or authorize or appoint any other Person to perform any of the
duties, covenants or obligations to be performed by it hereunder. If, pursuant
to any provision hereof, the duties of the Master Servicer or the Special
Servicer are transferred to a successor thereto, the Master Servicing Fee, the
Special Servicing Fee, any Workout Fee (except as expressly contemplated by
Section 3.11(c)) and/or any Liquidation Fee, as applicable, that accrues or
otherwise becomes payable pursuant hereto from and after the date of such
transfer shall be payable to such successor.

          SECTION 6.05.  Rights of Depositor, Trustee and Serviced Non-Trust
                         Mortgage Loan Noteholders in Respect of the Master
                         Servicer and the Special Servicer.

          The Master Servicer and the Special Servicer shall each afford the
Depositor, each Underwriter, the Trustee and each Serviced Non-Trust Mortgage
Loan Noteholder, upon reasonable notice, during normal business hours access to
all records maintained thereby in respect of its rights and obligations
hereunder. Upon reasonable request, the Master Servicer and the Special Servicer
shall each furnish the Depositor, each Underwriter, the Trustee and each
Serviced Non-Trust Mortgage Loan Noteholder with its most recent publicly
available financial statements (or, if not available, the most recent publicly
available audited annual financial statements of its corporate parent, on a
consolidated basis) and such other non-proprietary information as the Master
Servicer or the Special Servicer, as the case may be, shall determine in its
sole and absolute discretion as it possesses, which is relevant to the
performance of its duties hereunder and which it is not prohibited by applicable
law or contract from disclosing. The Depositor may, but is not obligated to,
enforce the obligations of the Master Servicer and the Special Servicer
hereunder and may, but is not obligated to, perform, or cause a designee to
perform, any defaulted obligation of the Master Servicer or Special Servicer
hereunder or exercise the rights of the Master Servicer and the Special Servicer
hereunder; provided, however, that neither the Master Servicer nor the Special
Servicer shall be relieved of any of its obligations hereunder by virtue of such
performance by the Depositor or its designee and, provided, further, that the
Depositor may not exercise any right pursuant to Section 7.01 to terminate the
Master Servicer or the Special Servicer as a party to this Agreement. The
Depositor shall not have any responsibility or liability for any action or
failure to act by the Master Servicer or the Special Servicer and is not
obligated to supervise the performance of the Master Servicer or the Special
Servicer under this Agreement or otherwise.

          SECTION 6.06.  Depositor, Master Servicer and Special Servicer to
                         Cooperate with Trustee.

          The Depositor, the Master Servicer and the Special Servicer shall each
furnish such reports, certifications and information as are reasonably requested
by the Trustee in order to enable it to perform its duties hereunder.

          SECTION 6.07.  Depositor, Special Servicer and Trustee to Cooperate
                         with Master Servicer.

          The Depositor, the Special Servicer and the Trustee shall each furnish
such reports, certifications and information as are reasonably requested by the
Master Servicer in order to enable it to perform its duties hereunder.


                                     -310-



          SECTION 6.08.  Depositor, Master Servicer and Trustee to Cooperate
                         with Special Servicer.

          The Depositor, the Master Servicer and the Trustee shall each furnish
such reports, certifications and information as are reasonably requested by the
Special Servicer in order to enable it to perform its duties hereunder.

          SECTION 6.09.  Designation of Special Servicer, Controlling Class
                         Representative, Class HAF Representative and Class SBC
                         Representative; Replacement of Special Servicer by the
                         Controlling Class and Others.

          (a) Subject to Section 6.09(d), the Majority Controlling Class
Certificateholder(s) may at any time and from time to time designate a Person to
serve as Special Servicer hereunder and to replace any existing Special Servicer
without cause or any Special Servicer that has resigned or otherwise ceased to
serve (including in connection with a termination pursuant to Section 7.01) as
Special Servicer; provided that the Majority Controlling Class
Certificateholder(s) may not designate any Person to act as successor Special
Servicer with respect to any Serviced Loan Combination (without the consent of
the related Serviced Non-Trust Noteholder(s), such consent not to be
unreasonably withheld) if such Person was previously terminated as Special
Servicer with respect to such Serviced Loan Combination due to an Event of
Default under any of clauses (i) through (v) of Section 7.01(a). Such Holder or
Holders shall so designate a Person to serve as replacement Special Servicer by
the delivery to the Trustee, the Depositor, the Master Servicer, each Serviced
Non-Trust Mortgage Loan Noteholder and the existing Special Servicer of a
written notice stating such designation. The Trustee shall, promptly after
receiving any such notice, deliver to the Rating Agencies an executed Notice and
Acknowledgment in the form attached hereto as Exhibit I-1. If such Holders have
not replaced the Special Servicer within 30 days of such Special Servicer's
resignation or the date such Special Servicer has ceased to serve in such
capacity, and subject to the prior rights of any particular party to appoint a
special servicer with respect to a Split Trust Mortgage Loan, a Split REO Trust
Mortgage Loan, the One New York Plaza Loan Combination and the Two Penn Center
Loan Combination in accordance with Section 6.09(d), the Trustee shall designate
a successor Special Servicer, subject to removal by the Majority Controlling
Class Certificateholder(s) or as and to the extent otherwise provided in Section
6.09(d) and appointment of a successor thereto pursuant to the terms of this
Section 6.09. Subject to Section 6.09(d) and the proviso to the first sentence
of this Section 6.09(a), any designated Person (whether designated by Holders of
the Controlling Class or by the Trustee) shall become the Special Servicer on
the date as of which the Trustee shall have received all of the following: (1)
written confirmation from each Rating Agency (and, if applicable, Fitch)
(obtained at the expense of the outgoing Special Servicer, in connection with a
resignation or a termination for cause, including pursuant to Section 7.01, and
otherwise at the expense of the Controlling Class Certificateholders
contemplated by the next paragraph) that the appointment of such Person will not
result in an Adverse Rating Event with respect to any Class of Certificates or
any outstanding class of Specially Designated Non-Trust Mortgage Loan Securities
rated by such rating agency; (2) an Acknowledgment of Proposed Special Servicer
in the form attached hereto as Exhibit I-2, executed by the designated Person;
and (3) an Opinion of Counsel (at the expense of the Person designated to become
the Special Servicer) to the effect that, upon the execution and delivery of the
Acknowledgment of Proposed Special Servicer, the designated Person shall be
bound by the terms of this Agreement and, subject to customary limitations, that
this Agreement shall be enforceable against the designated Person in accordance
with its


                                     -311-



terms. Subject to Section 6.09(d) and the proviso to the first sentence of this
Section 6.09(a), any existing Special Servicer shall be deemed to have resigned
simultaneously with such designated Person's becoming the Special Servicer
hereunder; provided, however, that (i) the outgoing Special Servicer shall
continue to be entitled to receive all amounts accrued or owing to it under this
Agreement on or prior to the effective date of such resignation, whether in
respect of Servicing Advances or otherwise, (ii) if the outgoing Special
Servicer was terminated without cause, it shall be entitled to a portion of
certain Workout Fees thereafter payable with respect to the Corrected Mortgage
Loans or otherwise (but only if and to the extent permitted by Section 3.11(c))
and (iii) the outgoing Special Servicer shall continue to be entitled to the
benefits of Section 6.03 notwithstanding any such resignation. The outgoing
Special Servicer shall cooperate with the Trustee and the replacement Special
Servicer in effecting the termination of the outgoing Special Servicer's
responsibilities and rights hereunder, including the transfer within two (2)
Business Days to the replacement Special Servicer for administration by it of
all cash amounts that shall at the time be or should have been credited by the
outgoing Special Servicer to a Custodial Account, a Servicing Account, a Reserve
Account or an REO Account or should have been delivered to the Master Servicer
or that are thereafter received with respect to Specially Serviced Mortgage
Loans and Administered REO Properties. The Trustee shall notify the other
parties hereto, the Certificateholders and the Serviced Non-Trust Mortgage Loan
Noteholders of any termination of the Special Servicer and appointment of a new
Special Servicer in accordance with this Section 6.09(a).

          Any out-of-pocket costs and expenses incurred in connection with the
removal (without cause) of a Special Servicer pursuant to this Section 6.09(a)
and its replacement by a Person designated by the Majority Controlling Class
Certificateholder(s), that are not paid by the replacement Special Servicer
shall be paid by such Holder or Holders. The rights of the Majority Controlling
Class Certificateholders to replace the Special Servicer under this Section
6.09(a) shall be subject to Section 6.09(d), as well as to the provisions of the
respective Co-Lender Agreement for each Serviced Loan Combination if and to the
extent that such Co-Lender Agreement entitles one or more of the related
Non-Trust Mortgage Loan Noteholders to be consulted in connection with such
replacement; and it shall be an additional condition to any such replacement
that the Majority Controlling Class Certificateholder(s) shall have fulfilled,
or caused the fulfillment of, any conditions precedent to such replacement that
are set forth in such Co-Lender Agreements.

          (b) The Majority Controlling Class Certificateholder(s) may also
select a representative (the "Controlling Class Representative") from whom the
Special Servicer will seek advice and approval and take direction under certain
circumstances, as described herein, and shall promptly notify the Trustee, the
Master Servicer and the Special Servicer of that selection. Notwithstanding the
foregoing, until a Controlling Class Representative is so selected in accordance
with the preceding sentence, or after receipt of a notice from the Majority
Controlling Class Certificateholder(s) that a Controlling Class Representative
is no longer designated, the Certificateholder (or, if the Certificates of the
Controlling Class are Book-Entry Certificates, the Certificate Owner), if any,
that beneficially owns more than 50% of the Class Principal Balance of the
Controlling Class of Certificates will be deemed to be the Controlling Class
Representative. The Controlling Class Representative shall be required to keep
all non-public information received by it in such capacity pursuant to this
Agreement confidential and, upon its designation as such, the Controlling Class
Representative (except with respect to the initial Controlling Class
Representative as provided in the following sentence) shall deliver to the
Trustee, the Master Servicer and the Special Servicer a written confirmation to
such effect, in the form of Exhibit O attached hereto (the "Controlling Class
Representative Confirmation"). The Controlling Class Representative Confirmation
shall also include confirmation of its acceptance of its appointment as


                                     -312-



Controlling Class Representative, an address and facsimile number for the
delivery of notices and other correspondence and a list of officers or employees
of such Person with whom the parties to this Agreement may deal (including their
names, titles, work addresses and facsimile numbers)). No appointment of any
Person as a Controlling Class Representative shall be effective until such
Person provides the Trustee and the Master Servicer with a Controlling Class
Representative Confirmation; provided that, upon its acquisition of all the
Class T Certificates, American Capital Strategies Ltd. shall be the initial
Controlling Class Representative without the need for delivery of a Controlling
Class Representative Confirmation, and by its acceptance of such designation,
shall be deemed to have agreed to keep all non-public information received by it
in such capacity from time to time pursuant to this Agreement confidential,
subject to applicable law.

          The Majority Class HAF Certificateholder(s), as certified by the
Certificate Registrar from time to time, shall also be entitled to select a
particular Holder or Certificate Owner of Class HAF Certificates as a
representative (the "Class HAF Representative") from whom the Special Servicer
will, as to any HAF Split Trust Mortgage Loan or any related REO Property,
during a Class HAF Control Period with respect thereto, seek advice and approval
under certain circumstances, as provided herein, and shall promptly notify the
Trustee, the Master Servicer and the Special Servicer of that selection;
provided, however, that until a Class HAF Representative is so selected or after
receipt of a notice from the Majority Class HAF Certificateholder(s) that a
Class HAF Representative is no longer designated, the Holder or Certificate
Owner, as applicable, of Class HAF Certificates that is entitled to the largest
percentage of Voting Rights allocated to the Class HAF Certificates will be the
Class HAF Representative. Each Class HAF Representative shall be required to
keep all non-public information received by it in such capacity pursuant to this
Agreement confidential.

          The Majority Class SBC Certificateholder(s), as certified by the
Certificate Registrar from time to time, shall also be entitled to select a
particular Holder or Certificate Owner of Class SBC Certificates as a
representative (the "Class SBC Representative") from whom the Special Servicer
will, as to the Sturbridge Commons Trust Mortgage Loan or any related REO
Property, during a Class SBC Control Period with respect thereto, seek advice
and approval under certain circumstances, as provided herein, and shall promptly
notify the Trustee, the Master Servicer and the Special Servicer of that
selection; provided, however, that until a Class SBC Representative is so
selected or after receipt of a notice from the Majority Class SBC
Certificateholder(s) that a Class SBC Representative is no longer designated,
the Holder or Certificate Owner, as applicable, of Class SBC Certificates that
is entitled to the largest percentage of Voting Rights allocated to the Class
SBC Certificates will be the Class SBC Representative. Each Class SBC
Representative shall be required to keep all non-public information received by
it in such capacity pursuant to this Agreement confidential.

          (c) Notwithstanding the foregoing, if the Controlling Class of
Certificates, the Class HAF Certificates or the Class SBC Certificates, as
applicable, consists or consist, as applicable, of Book-Entry Certificates, then
the rights of the Holders of the Certificates of the Controlling Class or the
Class HAF Certificates or the Class SBC Certificates, as applicable, set forth
in Section 6.09(a) or Section 6.09(b) above may be exercised directly by the
relevant Certificate Owner(s), provided that the identity of such Certificate
Owner(s) has been confirmed to the Trustee to its reasonable satisfaction. If
the Certificates of the Controlling Class consist of Book-Entry Certificates,
then any costs or expenses incurred in connection with determining the identity
of the Controlling Class Representative shall be paid by the Trust or, if paid
by the Trustee, reimbursed to the Trustee out of the Trust Fund (in any event,
out of amounts otherwise payable with respect to the Controlling Class of
Certificates). If the


                                     -313-



Class HAF Certificates and/or the Class SBC Certificates consist of Book-Entry
Certificates, then any costs or expenses incurred in connection with determining
the identity of the related Loan-Specific Class Representative shall be paid by
the Trust or, if paid by the Trustee, reimbursed to the Trustee out of the Trust
Fund (in any event, out of amounts otherwise payable with respect to the related
Class of Loan-Specific Certificates).

          (d) For so long as a Class HAF Control Period is in effect with
respect to any particular HAF Split Trust Mortgage Loan or any successor REO
Trust Mortgage Loan with respect thereto, the Class HAF Representative shall be
entitled, solely with respect to such HAF Split Trust Mortgage Loan or any
related REO Property, to exercise any and all rights to terminate, appoint
and/or replace the Special Servicer that are granted to the Majority Controlling
Class Certificateholder(s) pursuant to the first paragraph of Section 6.09(a),
in all cases subject to the same terms, conditions and limitations as are
applicable to any such termination, appointment and/or replacement by the
Majority Controlling Class Certificateholder(s). Notwithstanding anything herein
to the contrary, the Class HAF Representative shall not have any right to
terminate, replace or appoint any party as Special Servicer in respect of any
Mortgage Loan or REO Property other than a HAF Split Trust Mortgage Loan and any
related REO Property while a Class HAF Control Period is in effect with respect
thereto.

          For so long as a Class SBC Control Period is in effect with respect to
the Sturbridge Commons Trust Mortgage Loan or any successor REO Trust Mortgage
Loan with respect thereto, the Class SBC Representative shall be entitled,
solely with respect to the Sturbridge Commons Trust Mortgage Loan or any related
REO Property, to exercise any and all rights to terminate, appoint and/or
replace the Special Servicer that are granted to the Majority Controlling Class
Certificateholder(s) pursuant to the first paragraph of Section 6.09(a), in all
cases subject to the same terms, conditions and limitations as are applicable to
any such termination, appointment and/or replacement by the Majority Controlling
Class Certificateholder(s). Notwithstanding anything herein to the contrary, the
Class SBC Representative shall not have any right to terminate, replace or
appoint any party as Special Servicer in respect of any Mortgage Loan or REO
Property other than the Sturbridge Commons Trust Mortgage Loan and any related
REO Property while a Class SBC Control Period is in effect.

          The One New York Plaza Note A-2 Non-Trust Mortgage Loan Noteholder (in
its capacity as "Special Servicer Directing Lender" under the One New York Plaza
Co-Lender Agreement) shall be entitled, solely with respect to the One New York
Plaza Loan Combination, to exercise any and all rights to terminate, appoint
and/or replace the Special Servicer that are granted to the Majority Controlling
Class Certificateholder(s) pursuant to the first paragraph of Section 6.09(a),
in all cases subject to the same terms, conditions and limitations as are
applicable to any such termination, appointment and/or replacement by the
Majority Controlling Class Certificateholder(s). Notwithstanding anything herein
to the contrary, the One New York Plaza Note A-2 Non-Trust Mortgage Loan
Noteholder in respect of the One New York Plaza Loan Combination shall not have
any right to terminate, replace or appoint any party as Special Servicer in
respect of any Mortgage Loan or REO Property other than the One New York Plaza
Loan Combination and any related REO Property.

          For so long as no Serviced Loan Combination Change of Control Event
has occurred and is continuing with respect to the Two Penn Center Loan
Combination, the Two Penn Center Note B Non-Trust Mortgage Loan Noteholder (in
its capacity as Serviced Loan Combination Directing Lender with respect to the
Two Penn Center Loan Combination) shall be entitled, solely with respect to the
Two Penn Center Loan Combination, to exercise any and all rights to terminate,
appoint and/or replace the


                                     -314-



Special Servicer that are granted to the Majority Controlling Class
Certificateholder(s) pursuant to the first paragraph of Section 6.09(a), in all
cases subject to the same terms, conditions and limitations as are applicable to
any such termination, appointment and/or replacement by the Majority Controlling
Class Certificateholder(s). Notwithstanding anything herein to the contrary, the
Two Penn Center Note B Non-Trust Mortgage Loan Noteholder in respect of the Two
Penn Center Loan Combination shall not have any right to terminate, replace or
appoint any party as Special Servicer in respect of any Mortgage Loan or REO
Property other than the Two Penn Center Loan Combination and any related REO
Property while no Serviced Loan Combination Change of Control Event has occurred
and is continuing with respect to the Two Penn Center Loan Combination.

          Notwithstanding the foregoing, the Majority Controlling Class
Certificateholder(s) shall continue to have all rights to terminate, appoint
and/or replace a Special Servicer in accordance with Section 6.09; provided
that: (i) for so long as a Class HAF Control Period is in effect with respect to
a HAF Split Trust Mortgage Loan or any successor REO Trust Mortgage Loan with
respect thereto, the Majority Controlling Class Certificateholder(s) may not
terminate or replace, without cause, any Special Servicer appointed by the Class
HAF Representative with respect to such HAF Split Trust Mortgage Loan or any
related REO Property pursuant to this Section 6.09(d); (ii) for so long as a
Class SBC Control Period is in effect with respect to the Sturbridge Commons
Trust Mortgage Loan or any successor REO Trust Mortgage Loan with respect
thereto, the Majority Controlling Class Certificateholder(s) may not terminate
or replace, without cause, any Special Servicer appointed by the Class SBC
Representative with respect to the Sturbridge Trust Mortgage Loan or any related
REO Property pursuant to this Section 6.09(d); (iii) the Majority Controlling
Class Certificateholder(s) may not terminate or replace, without cause, any
Special Servicer appointed by the One New York Plaza Note A-2 Non-Trust Mortgage
Loan Noteholder with respect to the One New York Plaza Loan Combination or any
related REO Property pursuant to this Section 6.09(d); and (iv) for so long as
no Serviced Loan Combination Change of Control Event has occurred and is
continuing with respect to the Two Penn Center Loan Combination, the Majority
Controlling Class Certificateholder(s) may not terminate or replace, without
cause, any Special Servicer appointed by the Two Penn Center Note B Non-Trust
Mortgage Loan Noteholder with respect to the Two Penn Center Loan Combination or
any related REO Property pursuant to this Section 6.09(d).

          If a replacement special servicer is appointed with respect to a
Serviced Loan Combination or any related REO Property at the request of a
related Serviced Non-Trust Mortgage Loan Noteholder in accordance with Section
7.01(d) or with respect to a Split Trust Mortgage Loan, the One New York Plaza
Loan Combination, the Two Penn Center Loan Combination or any REO Property
related to any of the foregoing at the request of any appropriate party in
accordance with this Section 6.09(d), then such replacement special servicer
shall be referred to in this Agreement as a "Loan Combination/Loan-Specific
Special Servicer." If the Person acting as Loan Combination/Loan-Specific
Special Servicer is different from the Person acting as Special Servicer with
respect to the Mortgage Pool (exclusive of the Split Trust Mortgage Loans, the
Combination Trust Mortgage Loans and/or any successor REO Trust Mortgage Loans
with respect thereto), then the provisions of Section 7.01(e) shall apply to
such Loan Combination/Loan-Specific Special Servicer in respect of such
circumstances.

          (e) Any existing Loan Combination/Loan-Specific Special Servicer
removed pursuant to Section 6.09(d) shall be deemed to have resigned
simultaneously with its replacement becoming the new Loan Combination/Loan-
Specific Special Servicer hereunder with respect to the subject Loan Combination
or the subject Split Trust Mortgage Loan, as applicable, or any related REO


                                     -315-



Property; provided, however, that (i) the outgoing Loan Combination/Loan-
Specific Special Servicer shall continue to be entitled to receive all amounts
accrued or owing to it under this Agreement on or prior to the effective date of
such resignation, whether in respect of Servicing Advances or otherwise, in
respect of the subject Loan Combination or the subject Split Trust Mortgage
Loan, as applicable, or any related REO Property, (ii) if the outgoing Loan
Combination/Loan-Specific Special Servicer was terminated without cause, it
shall be entitled to a portion of certain Workout Fees thereafter payable with
respect to any Corrected Mortgage Loan(s) constituting the subject Loan
Combination or the subject Split Trust Mortgage Loan, as applicable, but only if
and to the extent permitted by Section 3.11(c), and (iii) the outgoing Loan
Combination/Loan-Specific Special Servicer shall continue to be entitled to the
benefits of Section 6.03 notwithstanding any such resignation. The outgoing Loan
Combination/Loan-Specific Special Servicer shall cooperate with the Trustee and
its replacement in effecting the termination of the responsibilities and rights
hereunder of the outgoing Loan Combination/Loan-Specific Special Servicer,
including the transfer within two (2) Business Days to the replacement Loan
Combination/Loan-Specific Special Servicer for administration by it of all cash
amounts relating to the subject Loan Combination or the subject Split Trust
Mortgage Loan, as applicable, or any related REO Property that shall at the time
be or should have been credited by the Loan Combination/Loan-Specific Special
Servicer to a Custodial Account, a Servicing Account, a Reserve Account or an
REO Account or should have been delivered to the Master Servicer or that are
thereafter received with respect to the subject Loan Combination, subject Split
Trust Mortgage Loan and/or any related REO Property. The Trustee shall notify
the other parties hereto and the Certificateholders of any termination of a Loan
Combination/Loan-Specific Special Servicer and/or appointment of a new Loan
Combination/Loan-Specific Special Servicer in accordance with Section 6.09(d).

          Any out-of-pocket costs and expenses incurred in connection with the
removal (without cause) of a Loan Combination/Loan-Specific Special Servicer,
and the appointment of its replacement, pursuant to Section 6.09(d), that are
not paid by the replacement Loan Combination/Loan-Specific Special Servicer,
shall be paid by the Person(s) effecting the removal in accordance with Section
6.09(d). The rights of any Serviced Loan Combination Controlling Party to
replace the related Loan Combination/Loan-Specific Special Servicer under
Section 6.09(d) shall be subject to the provisions of the related Co-Lender
Agreement; and it shall be an additional condition to any such replacement that
such Serviced Loan Combination Controlling Party shall have fulfilled, or caused
the fulfillment of, any conditions precedent to such replacement that are set
forth in the related Co-Lender Agreement.

          SECTION 6.10.  Master Servicer or Special Servicer as Owner of a
                         Certificate.

          The Master Servicer, the Special Servicer or any Affiliate of either
of them may become the Holder of (or, in the case of a Book-Entry Certificate,
Certificate Owner with respect to) any Certificate with (except as otherwise set
forth in the definition of "Certificateholder") the same rights it would have if
it were not the Master Servicer or the Special Servicer or an Affiliate thereof.
If, at any time during which the Master Servicer or the Special Servicer or an
Affiliate of the Master Servicer or the Special Servicer is the Holder of (or,
in the case of a Book-Entry Certificate, Certificate Owner with respect to) any
Certificate, the Master Servicer or the Special Servicer proposes to take action
(including for this purpose, omitting to take action) that is not expressly
prohibited by the terms hereof and would not, in the Master Servicer's or the
Special Servicer's reasonable, good faith judgment, violate the Servicing
Standard, but that, if taken, might nonetheless, in the Master Servicer's or the
Special Servicer's good faith judgment, be considered by other Persons to
violate the Servicing Standard, then the Master Servicer or the Special Servicer
may (but need not) seek the approval of the Certificateholders to such


                                     -316-



action by delivering to the Trustee a written notice that (a) states that it is
delivered pursuant to this Section 6.10, (b) identifies the Percentage Interest
in each Class of Certificates beneficially owned by the Master Servicer or an
Affiliate thereof or the Special Servicer or an Affiliate thereof, as
appropriate, and (c) describes in reasonable detail the action that the Master
Servicer or the Special Servicer proposes to take. The Trustee, upon receipt of
such notice, shall forward it to the Certificateholders (other than the Master
Servicer and its Affiliates or the Special Servicer and its Affiliates, as
appropriate), together with such instructions for response as the Trustee shall
reasonably determine. If at any time Certificateholders holding greater than 50%
of the Voting Rights of all Certificateholders (calculated without regard to the
Certificates beneficially owned by the Master Servicer or its Affiliates or the
Special Servicer or its Affiliates, as appropriate) shall have failed to object
in writing (with a copy to the related Serviced Non-Trust Mortgage Loan
Noteholder(s), if a Serviced Loan Combination is involved) to the proposal
described in the written notice, and if the Master Servicer or the Special
Servicer shall act as proposed in the written notice within 30 days, such action
shall be deemed to comply with, but not modify, the Servicing Standard. The
Trustee shall be entitled to reimbursement from the Master Servicer or the
Special Servicer, as applicable, for the reasonable expenses of the Trustee
incurred pursuant to this paragraph. It is not the intent of the foregoing
provision that the Master Servicer or the Special Servicer be permitted to
invoke the procedure set forth herein with respect to routine servicing matters
arising hereunder, but rather only in the case of unusual circumstances.

          SECTION 6.11.  Certain Powers of the Controlling Class Representative,
                         the Class HAF Representative and the Class SBC
                         Representative.

          (a) Each of the Master Servicer and the Special Servicer shall notify
(in writing) the Controlling Class Representative (and, if a Split Trust
Mortgage Loan is involved, the Class HAF Representative or the Class SBC
Representative, as applicable) of its intention to take any Specially Designated
Servicing Action with respect to any Serviced Mortgage Loan and shall provide
the Controlling Class Representative (and, if a Split Trust Mortgage Loan is
involved, the Class HAF Representative or the Class SBC Representative, as
applicable) with all reasonably requested information with respect thereto.
Subject to Section 6.11(b) and the penultimate paragraph of this Section
6.11(a), the Controlling Class Representative will be entitled to advise the
Special Servicer (in the event the Special Servicer is authorized under this
Agreement to take the subject action) or the Master Servicer (in the event the
Master Servicer is authorized under this Agreement to take the subject action),
as applicable, with respect to any and all Specially Designated Servicing
Actions relating to the Serviced Mortgage Loans and any Administered REO
Properties; and, further subject to Section 6.11(b) and the penultimate
paragraph of this Section 6.11(a), neither the Master Servicer nor the Special
Servicer will be permitted to take (or, in the case of the Special Servicer, if
and to the extent applicable, consent to the Master Servicer's taking) any
Specially Designated Servicing Action with respect to any Serviced Mortgage Loan
or Administered REO Property if the Controlling Class Representative has
objected in writing within ten (10) Business Days (or, in the case of the
Specially Designated Servicing Actions set forth in clause (b)(iii), clause
(b)(viii), clause (b)(x) and, in the case of Performing Serviced Mortgage Loans,
clause (b)(ix), of the definition of "Specially Designated Servicing Action,"
within five (5) Business Days) of having been notified in writing thereof and
having been provided with all information that the Controlling Class
Representative has reasonably requested with respect thereto promptly following
its receipt of the subject notice (it being understood and agreed that if such
written objection has not been received by the Special Servicer or the Master
Servicer, as applicable, within such ten (10) Business Day (or five (5) Business
Day, as applicable) period, then the Controlling Class Representative will be
deemed to have approved the taking of the subject action); provided that, if the


                                     -317-



Special Servicer or the Master Servicer, as applicable, determines that failure
to take such action would violate the Servicing Standard, then the Master
Servicer or the Special Servicer may take (or, in the case of the Special
Servicer, if and to the extent applicable, consent to the Master Servicer's
taking) any such action without waiting for the Controlling Class
Representative's response; and provided, further, that the foregoing rights of
the Controlling Class Representative shall not relate to any Serviced Mortgage
Loan that is part of, or any Administered REO Property that relates to, a
Serviced Loan Combination, regarding which the rights and powers of the
specified Persons set forth under Section 6.12 are instead applicable.

          In addition, subject to Section 6.11(b) and the next paragraph of this
Section 6.11(a), the Controlling Class Representative may direct the Special
Servicer to take, or to refrain from taking, any actions with respect to the
servicing and/or administration of a Specially Serviced Mortgage Loan or an
Administered REO Property as the Controlling Class Representative may deem
advisable or as to which provision is otherwise made herein; provided that the
foregoing rights of the Controlling Class Representative shall not relate to any
Specially Serviced Mortgage Loan that is part of, or any Administered REO
Property that relates to, a Serviced Loan Combination. Upon reasonable request,
the Special Servicer shall provide the Controlling Class Representative with any
information in such servicer's possession with respect to such matters,
including its reasons for determining to take a proposed action; provided that
such information shall also be provided, in a written format, to the Trustee,
who shall make it available for review pursuant to Section 8.14(b).

          Notwithstanding the foregoing, but subject to Section 6.11(b), (i) for
so long as a Class HAF Control Period is in effect with respect to a particular
HAF Split Trust Mortgage Loan or any related REO Property, the Class HAF
Representative (rather than the Controlling Class Representative), and (ii) for
so long as a Class SBC Control Period is in effect with respect to the
Sturbridge Commons Trust Mortgage Loan or any related REO Property, the Class
SBC Representative (rather than the Controlling Class Representative), shall be
entitled to exercise all of the rights and powers of the Controlling Class
Representative specified in the two preceding paragraphs, including rights to
approve or consent to actions of, to advise and/or to direct the Special
Servicer, with respect to, but solely with respect to, the subject Split Trust
Mortgage Loan or any related REO Property; provided that, under circumstances
where the Controlling Class Representative is not entitled to exercise all of
the rights and powers of the Controlling Class Representative specified in the
two preceding paragraphs with respect to a particular Split Mortgage Loan,
nothing herein shall be intended to limit the right of the Controlling Class
Representative to consult with the Master Servicer or the Special Servicer, as
applicable, regarding such Split Trust Mortgage Loan or a related REO Property,
and during the ten (10) Business Day (or five (5) Business Day, as applicable)
period referred to above (or such shorter period as is contemplated by the
second preceding paragraph), the Master Servicer or the Special Servicer, as
applicable, shall consult with the Controlling Class Representative regarding
its views as to the proposed action regarding such Split Trust Mortgage Loan or
a related REO Property (but may, in its sole discretion, reject any advice,
objection or direction from the Controlling Class Representative) and, upon
reasonable request, the Master Servicer or the Special Servicer, as applicable,
shall provide the Controlling Class Representative with any information in such
servicer's possession with respect to such matters, including its reasons for
determining to take a proposed action.

          The Master Servicer (with respect to Performing Serviced Mortgage
Loans) or the Special Servicer (with respect to Specially Serviced Mortgage
Loans), as applicable, shall notify the Controlling Class Representative (and,
if a Split Trust Mortgage Loan is involved, the Class HAF


                                     -318-



Representative or the Class SBC Representative, as applicable) of any release or
substitution of collateral for a Serviced Mortgage Loan that is not part of a
Loan Combination even if such release or substitution is required by the terms
of such Serviced Mortgage Loan.

          (b) Notwithstanding anything herein to the contrary, no advice,
direction or objection from or by the Controlling Class Representative, the
Class HAF Representative or the Class SBC Representative, as applicable, with
respect to any Serviced Mortgage Loan or Administered REO Property, as
contemplated by Section 6.11(a) or any other provision of this Agreement, may
(and the Special Servicer and the Master Servicer shall each ignore and act
without regard to any such advice, direction or objection that such servicer has
determined, in its reasonable, good faith judgment, would) require or cause the
Master Servicer or the Special Servicer, as applicable, to violate any provision
of this Agreement (exclusive of Section 6.11(a)) (including such servicer's
obligation to act in accordance with the Servicing Standard), the related loan
documents (including any applicable co-lender and/or intercreditor agreements)
or applicable law (including the REMIC Provisions). Furthermore, the Special
Servicer shall not be obligated to seek approval from the Controlling Class
Representative, the Class HAF Representative or the Class SBC Representative, as
applicable, pursuant to Section 6.11(a), for any actions to be taken by the
Special Servicer with respect to the workout or liquidation of any particular
Specially Serviced Trust Mortgage Loan if:

               (i) the Special Servicer has, as provided in Section 6.11(a),
     notified the Controlling Class Representative, the Class HAF Representative
     or the Class SBC Representative, as appropriate, in writing of various
     actions that the Special Servicer proposes to take with respect to the
     workout or liquidation of such Specially Serviced Trust Mortgage Loan; and

               (ii) for 60 days following the first such notice, the Controlling
     Class Representative, the Class HAF Representative or the Class SBC
     Representative, as the case may be, has objected to all of those proposed
     actions and has failed to suggest any alternative actions that the Special
     Servicer considers to be consistent with the Servicing Standard.

          Also notwithstanding anything herein to the contrary, the provisions
of Section 6.11(a), and the rights and powers of the Controlling Class
Representative provided for in Section 6.11(a), shall not apply to any Serviced
Loan Combination or any related Administered REO Property; provided that this
paragraph is not intended to limit any rights or powers that the Controlling
Class Representative may have under Section 6.12.

          (c) The Controlling Class Representative is hereby authorized to
exercise the rights and powers of the Trustee, as holder of the Mortgage Note
for each Outside Serviced Trust Mortgage Loan, under Sections 3.02, 4.03 and
7.01 of the related Co-Lender Agreement (and any corresponding provisions of the
related Outside Servicing Agreement), including for purposes of exercising, (i)
either individually or together with related Non-Trust Mortgage Loan
Noteholder(s), as the case may be, consent rights, consultation rights, rights
to direct servicing and rights to replace the related Outside Special Servicer
and (ii) any related purchase option and cure rights; provided that any purchase
option or cure rights may be exercised by the Controlling Class Representative
only in its individual capacity with its own funds. Promptly following the
initial such appointment of a Controlling Class Representative and any
subsequent such appointment of a successor Controlling Class Representative,
with respect to each Outside Serviced Trust Mortgage Loan, the Trustee shall
inform the related Outside


                                     -319-



Master Servicer, the related Outside Special Servicer and the related Non-Trust
Mortgage Loan Noteholder(s) (and from time to time shall ensure that such
parties remain similarly informed) that the Controlling Class Representative is
entitled, to the fullest extent permitted under the related Co-Lender Agreement,
to exercise such rights and powers of the Trustee, in its capacity as holder of
the Mortgage Note for the subject Outside Serviced Trust Mortgage Loan, under
Sections 3.02, 4.03 and 7.01 of the related Co-Lender Agreement (and any
corresponding provisions of the related Outside Servicing Agreement), and,
further, the Trustee shall take such other actions as may be required under the
related Co-Lender Agreement in order to permit the Controlling Class
Representative to exercise such rights and powers. The Controlling Class
Representative shall be subject to the same limitations, constraints and
restrictions in exercising such rights and powers as would be applicable to the
Trustee, in its capacity as holder of the Mortgage Note for the subject Outside
Serviced Trust Mortgage Loan. In addition, subject to Section 7.01(f) and each
other section hereof that specifically addresses a particular matter with
respect to any Outside Serviced Trust Mortgage Loan, if the Trustee is requested
to take any action in its capacity as holder of the Mortgage Note for such
Outside Serviced Trust Mortgage Loan, pursuant to the related Co-Lender
Agreement and/or the related Outside Servicing Agreement, then the Trustee will
notify (in writing), and act in accordance with the instructions of, the
Controlling Class Representative; provided that, if such instructions are not
provided within the prescribed time period, then the Trustee, subject to
Sections 8.01 and 8.02, shall take such action or inaction as it deems to be in
the best interests of the Certificateholders (as a collective whole) and shall
have all rights and powers incident thereto; and provided, further, that the
Trustee, with respect to any Outside Serviced Trust Mortgage Loan or Outside
Administered REO Property, (i) shall not be required to take any action that
relates to directing or approving any servicing related action under the related
Outside Servicing Agreement or the related Outside Co-Lender Agreement, to the
extent that the Controlling Class Representative has been notified thereof and
has failed to provide instructions with respect to such action within the
prescribed time period, and (ii) shall not take any action that is not permitted
under applicable law or the terms of the related Co-Lender Agreement or the
related Outside Servicing Agreement or any action that is, in the good faith,
reasonable discretion of the Trustee, materially adverse to the interests of the
Certificateholders (as a collective whole).

          (d) Neither the Controlling Class Representative nor any Loan-Specific
Class Representative will have any liability to the Certificateholders for any
action taken, or for refraining from the taking of any action, pursuant to this
Agreement (whether pursuant to this Section 6.11 or otherwise), or for errors in
judgment; provided, however, that neither of the Controlling Class
Representative nor any Loan-Specific Class Representative will be protected
against any liability to any Controlling Class Certificateholder or
Loan-Specific Class Certificateholder, as applicable, that would otherwise be
imposed by reason of willful misfeasance, bad faith or negligence in the
performance of duties or by reason of negligent disregard of obligations or
duties. Each Certificateholder acknowledges and agrees, by its acceptance of its
Certificates, that: (i) the Controlling Class Representative may, and is
permitted hereunder to, have special relationships and interests that conflict
with those of Holders of one or more Classes of Certificates; (ii) the
Controlling Class Representative may, and is permitted hereunder to, act solely
in the interests of the Holders of the Controlling Class of Certificates; (iii)
the Controlling Class Representative does not have any duties or liability to
the Holders of any Class of Certificates other than the Controlling Class of
Certificates; (iv) the Controlling Class Representative may, and is permitted
hereunder to, take actions that favor interests of the Holders of the
Controlling Class of Certificates over the interests of the Holders of one or
more other Classes of Certificates; (v) the Controlling Class Representative
shall not be deemed to have been negligent or reckless, or to have acted in bad
faith or engaged in willful misconduct, by reason of its having acted solely in
the interests
                                     -320-



of the Holders of the Controlling Class of Certificates; and (vi) the
Controlling Class Representative shall have no liability whatsoever for having
acted solely in the interests of the Holders of the Controlling Class of
Certificates, and no Certificateholder may take any action whatsoever against
the Controlling Class Representative, any Holder of the Controlling Class of
Certificates or any director, officer, employee, agent or principal thereof for
having so acted. Each Certificateholder acknowledges and agrees, by its
acceptance of its Certificates, that: (i) each Loan-Specific Class
Representative may, and is permitted hereunder to, have special relationships
and interests that conflict with those of Holders of one or more Classes of
Certificates; (ii) each Loan-Specific Class Representative may, and is permitted
hereunder to, act solely in the interests of the Holders of the Classes of
Loan-Specific Certificates for which it acts as Loan-Specific Class
Representative (iii) the Loan-Specific Class Representatives do not have any
duties or liability to the Holders of any Class of Certificates other than the
Class of Loan-Specific Certificates for which it acts as Loan-Specific Class
Representative; (iv) each Loan-Specific Class Representative may, and is
permitted hereunder to, take actions that favor interests of the Holders of the
Class of Loan-Specific Certificates for which it acts as Loan-Specific Class
Representative over the interests of the Holders of one or more other Classes of
Certificates; (v) the Loan-Specific Class Representatives shall not be deemed to
have been negligent or reckless, or to have acted in bad faith or engaged in
willful misconduct, by reason of its having acted solely in the interests of the
Holders of the Class of Loan-Specific Certificates for which it acts as
Loan-Specific Class Representative; and (vi) the Loan-Specific Class
Representatives shall have no liability whatsoever for having acted solely in
the interests of the Holders of the Class of Loan-Specific Certificates for
which it acts as Loan-Specific Class Representative, and no Certificateholder
may take any action whatsoever against any Loan-Specific Class Representative,
any Holder of the Controlling Class of Certificates or any director, officer,
employee, agent or principal thereof for having so acted.

          SECTION 6.12.  Certain Matters Regarding the Serviced Loan
                         Combinations.

          (a) Each of the Master Servicer and the Special Servicer, as
applicable, shall notify (in writing and, if applicable, in accordance with the
related Co-Lender Agreement) the Controlling Class Representative, the related
Non-Trust Mortgage Loan Noteholder(s) and, if different, the related Serviced
Loan Combination Controlling Party of its intention to take any Specially
Designated Servicing Action with respect to any Serviced Loan Combination or
related REO Property and shall provide each such party with all reasonably
requested information with respect thereto. Subject to Section 6.12(b), and
further subject to Section 3.01(b), Section 3.01(c) and Section 3.02(b) of the
related Co-Lender Agreement (or, in the case of the One New York Plaza Loan
Combination, Section 4(f) of the One New York Plaza Co-Lender Agreement), the
applicable Serviced Loan Combination Controlling Party will be entitled to
advise the Special Servicer (in the event the Special Servicer is authorized
under this Agreement to take the subject action) or the Master Servicer (in the
event the Master Servicer is authorized under this Agreement to take the subject
action), as applicable, with respect to any and all Specially Designated
Servicing Actions with respect to a Serviced Loan Combination or any related REO
Property; and, further subject to Section 6.12(b) of this Agreement and Section
3.02(b) of the related Co-Lender Agreement (or, in the case of the One New York
Plaza Loan Combination, Section 4(f) of the One New York Plaza Co-Lender
Agreement), neither the Master Servicer nor the Special Servicer shall be
permitted to take (or, in the case of the Special Servicer, if and when
appropriate hereunder, to consent to the Master Servicer's taking) any of the
related Specially Designated Servicing Actions with respect to a Serviced Loan
Combination or any related REO Property if the applicable Serviced Loan
Combination Controlling Party has objected in writing within ten (10) Business
Days of the applicable Serviced Loan Combination Controlling Party having been
notified in


                                     -321-



writing thereof and having been provided with all reasonably requested
information with respect thereto (it being understood and agreed that if such
written objection to the subject action on the part of the applicable Serviced
Loan Combination Controlling Party has not been received by the Master Servicer
or the Special Servicer, as applicable, within such ten (10) Business Day
period, then the applicable Serviced Loan Combination Controlling Party will be
deemed to have approved of the subject action); provided that, if the Special
Servicer or the Master Servicer, as applicable, determines that immediate action
is necessary to protect the interests of the Certificateholders and the related
Serviced Non-Trust Mortgage Loan Noteholder(s) (as a collective whole), then the
Special Servicer or the Master Servicer, as the case may be, may take (or, in
the case of the Special Servicer, if and when appropriate hereunder, may consent
to the Master Servicer's taking) any such action without waiting for the
applicable Serviced Loan Combination Controlling Party's response; and provided,
further, that, under circumstances where the Controlling Class Representative is
not the applicable Serviced Loan Combination Controlling Party, nothing herein
shall be intended to limit the right of the Controlling Class Representative to
consult with the Master Servicer or the Special Servicer, as applicable,
regarding any Serviced Loan Combination or related REO Property, and during the
ten (10) Business Day period referred to above (or such shorter period as is
contemplated by the immediately preceding proviso), the Master Servicer or the
Special Servicer, as applicable, shall consult with the Controlling Class
Representative regarding its views as to the proposed action (but may, in its
sole discretion, reject any advice, objection or direction from the Controlling
Class Representative) and, upon reasonable request, the Master Servicer or the
Special Servicer, as applicable, shall provide the Controlling Class
Representative with any information in such servicer's possession with respect
to such matters, including its reasons for determining to take a proposed
action.

          In addition, subject to Section 6.12(b), and further subject to
Section 3.01(b), Section 3.01(c) and Section 3.02(b) of the related Co-Lender
Agreement (or, in the case of the One New York Plaza Loan Combination, Section
4(f) of the One New York Plaza Co-Lender Agreement), if and to the extent
provided for under the subject Co-Lender Agreement, the applicable Serviced Loan
Combination Controlling Party may direct the Special Servicer or the Master
Servicer, as appropriate based on their respective duties hereunder, to take, or
to refrain from taking, such actions with respect to each Serviced Loan
Combination or any related REO Property as the applicable Serviced Loan
Combination Controlling Party may deem consistent with the related Co-Lender
Agreement or as to which provision is otherwise made in the related Co-Lender
Agreement. Upon reasonable request, the Special Servicer or the Master Servicer,
as appropriate based on their respective duties hereunder, shall, with respect
to each Serviced Loan Combination or any related REO Property, provide the
applicable Serviced Loan Combination Controlling Party with any information in
such servicer's possession with respect to such matters, including its reasons
for determining to take a proposed action; provided that such information shall
also be provided, in a written format, to the Trustee who shall make it
available for review pursuant to Section 8.14(b). Promptly following the Special
Servicer or the Master Servicer receiving any direction with respect to a
Serviced Loan Combination or any related REO Property from the applicable
Serviced Loan Combination Controlling Party as contemplated by this paragraph,
and in any event prior to acting on such direction, such servicer shall notify
the Trustee, the Controlling Class Representative (if it is not the applicable
Serviced Loan Combination Controlling Party) and each related Serviced Non-Trust
Mortgage Loan Noteholder (if neither it nor its designee is the applicable
Serviced Loan Combination Controlling Party).

          Each of the Master Servicer (with respect to Performing Serviced
Mortgage Loans) and the Special Servicer (with respect to Specially Serviced
Mortgage Loans), as applicable, shall notify the


                                     -322-



related Serviced Non-Trust Mortgage Loan Noteholder, the Controlling Class
Representative and any other Person that may be the applicable Serviced Loan
Combination Controlling Party of any release or substitution of collateral for a
Serviced Loan Combination even if such release or substitution is required by
the terms of such Serviced Loan Combination.

          (b) Notwithstanding anything herein to the contrary, no advice,
direction or objection with respect to any Serviced Loan Combination or related
REO Property from or by the applicable Serviced Loan Combination Controlling
Party, as contemplated by Section 6.12(a), may (and the Special Servicer and the
Master Servicer shall each ignore and act without regard to any such advice,
direction or objection that the Special Servicer or the Master Servicer, as
applicable, has determined, in its reasonable, good faith judgment, will)
require, cause or permit such servicer to violate any provision of the related
Co-Lender Agreement or this Agreement (exclusive of Section 6.12(a)) (including
such servicer's obligation to act in accordance with the Servicing Standard),
the related loan documents or applicable law or result in an Adverse REMIC Event
or an Adverse Grantor Trust Event. Furthermore, neither the Special Servicer nor
the Master Servicer shall be obligated to seek approval from the applicable
Serviced Loan Combination Controlling Party for any actions to be taken by such
servicer with respect to the workout or liquidation of any Serviced Loan
Combination if: (i) such servicer has, as provided in Section 6.12(a), notified
the applicable Serviced Loan Combination Controlling Party, in writing of
various actions that such servicer proposes to take with respect to the workout
or liquidation of such Serviced Loan Combination; and (ii) for 60 days following
the first such notice, the applicable Serviced Loan Combination Controlling
Party has objected to all of those proposed actions and has failed to suggest
any alternative actions that such servicer considers to be consistent with the
Servicing Standard.

          (c) The Serviced Loan Combination Controlling Party for a Serviced
Loan Combination will not have any liability to the Trust or the
Certificateholders, in the case of a related Serviced Non-Trust Mortgage Loan
Noteholder or its designee acting in such capacity, or to the related Serviced
Non-Trust Mortgage Loan Noteholder(s), in the case of the Controlling Class
Representative acting in such capacity, for any action taken, or for refraining
from the taking of any action, in good faith pursuant to this Agreement or the
related Co-Lender Agreement, or for errors in judgment; provided, however, that
such Serviced Loan Combination Controlling Party will not be protected against
any liability which would otherwise be imposed by reason of willful misfeasance,
bad faith or negligence in the performance of duties or by reason of negligent
disregard of obligations or duties.

          (d) The Serviced Loan Combination Directing Lender for a Serviced Loan
Combination may, in accordance with Section 3.02(d) of the related Co-Lender
Agreement (or, in the case of the One New York Plaza Loan Combination, Section
4(f) of the One New York Plaza Co-Lender Agreement), designate a representative
to exercise its rights and powers under Section 3.02 of the related Co-Lender
Agreement (or, in the case of the One New York Plaza Loan Combination, Section
4(f) of the One New York Plaza Co-Lender Agreement) and this Section 6.12 or
otherwise under the related Co-Lender Agreement and this Agreement. In that
regard, upon the occurrence and continuance of a Serviced Loan Combination
Change of Control Event (if applicable) with respect to a Serviced Loan
Combination or related REO Property, and/or if and for so long as the Trust, as
holder of the Serviced Combination Trust Mortgage Loan in such Serviced Loan
Combination (or any successor REO Trust Mortgage Loan with respect thereto), is
or may be part of, as applicable, the applicable Serviced Loan Combination
Directing Lender, then the Controlling Class Representative (i) is hereby
designated as the representative of the Trust for purposes of or in connection
with exercising the rights and powers


                                     -323-



of the applicable Serviced Loan Combination Directing Lender or Serviced Loan
Combination Controlling Party, as applicable, under Section 3.02 of the related
Co-Lender Agreement (or, in the case of the One New York Plaza Loan Combination,
Section 4(f) of the One New York Plaza Co-Lender Agreement) and (ii) shall be or
may be part of, as applicable, the applicable Serviced Loan Combination
Controlling Party hereunder. The Trustee shall take such actions as are
necessary or appropriate to make such designation effective in accordance with
Section 3.02(d) of the related Co-Lender Agreement (or, in the case of the One
New York Plaza Loan Combination, Section 4(f) of the One New York Plaza
Co-Lender Agreement), including providing notices to the related Serviced
Non-Trust Mortgage Loan Noteholder(s). The Master Servicer shall provide the
parties to this Agreement with notice of the occurrence of a Serviced Loan
Combination Change of Control Event (if applicable) with respect to any Serviced
Loan Combination or related REO Property, promptly upon becoming aware thereof.

          (e) Each related Serviced Non-Trust Mortgage Loan Noteholder shall be
entitled to receive, upon request, a copy of any notice or report required to be
delivered (upon request or otherwise) to the Trustee with respect to a Serviced
Loan Combination or any related REO Property by any other party hereto. Subject
to the related Co-Lender Agreement, any such other party shall be permitted to
require payment of a sum sufficient to cover the reasonable costs and expenses
of providing such copies in accordance with this Section 6.12(e).

          (f) Notwithstanding anything herein to the contrary, any appointment
of a successor Special Servicer hereunder, insofar as it affects any Serviced
Loan Combination or any related REO Property, will be subject to any
consultation rights of the related Serviced Non-Trust Mortgage Loan
Noteholder(s) expressly provided for under the related Co-Lender Agreement.

          (g) The parties hereto recognize and acknowledge, in the case of any
Serviced Loan Combination, the rights of the related Serviced Non-Trust Mortgage
Loan Noteholder under the related Co-Lender Agreement, including: (i) in the
case of a Serviced A/B Loan Combination, the right of the related Serviced
Subordinate Non-Trust Mortgage Loan Noteholder to purchase the related Serviced
Combination Trust Mortgage Loan under the circumstances contemplated by Section
4.03 of the related Co-Lender Agreement; and (ii) in the case of the Two Penn
Center Loan Combination, the right of the related Serviced Subordinate Non-Trust
Mortgage Loan Noteholder to exercise cure rights with respect to the Two Penn
Center Trust Mortgage Loan to the extent provided in the Two Penn Center
Co-Lender Agreement. In connection with the foregoing, the Master Servicer (if
the subject Serviced Combination Trust Mortgage Loan is a Performing Serviced
Mortgage Loan) or the Special Servicer (if the subject Serviced Combination
Trust Mortgage Loan is a Specially Serviced Mortgage Loan), as applicable, shall
take all actions required on the part of the holder of such Serviced Combination
Trust Mortgage Loan or contemplated to be performed by a servicer, in any case,
under the related Co-Lender Agreement, including the delivery of all necessary
notices on a timely basis and/or the calculation of the applicable purchase
price, as well as all other actions necessary and appropriate to effect the
transfer of such Serviced Combination Trust Mortgage Loan (in connection with
the purchase thereof under the related Co-Lender Agreement) to any related
Serviced Subordinate Non-Trust Mortgage Loan Noteholder or its designee. Further
in connection with the foregoing, with respect to any Serviced Loan Combination
as to which the related Co-Lender Agreement provides for cure rights on the part
of any related Serviced Subordinate Non-Trust Mortgage Loan Noteholder, the
Master Servicer (if the subject Serviced Combination Trust Mortgage Loan is a
Performing Serviced Mortgage Loan) or the Special Servicer (if the subject
Serviced Combination Trust Mortgage Loan is a Specially Serviced Mortgage Loan),
as applicable, shall notify such Serviced Subordinate Non-Trust Mortgage Loan
Noteholder (i) of any


                                     -324-



event of default with respect to the subject Serviced Loan Combination that is
susceptible of cure under the related Co-Lender Agreement, promptly (and, in any
event, within two Business Days) after the applicable servicer has actual
knowledge thereof (although such notice is not required to state whether such
event of default is susceptible of cure thereunder), and (ii) of any material
event of default (although such notice is not required to state whether such
event of default is material).

          (h) The Master Servicer (if the related Serviced Combination Trust
Mortgage Loan is a Performing Serviced Mortgage Loan) or the Special Servicer
(if the related Serviced Combination Trust Mortgage Loan is a Specially Serviced
Mortgage Loan), as applicable, shall take all actions relating to the servicing
and/or administration of, and the preparation and delivery of reports and other
information with respect to, each Serviced Loan Combination or any related REO
Property required to be performed by the holder of the related Serviced
Combination Trust Mortgage Loan or contemplated to be performed by a servicer,
in any case pursuant to the related Co-Lender Agreement and/or any related
mezzanine loan intercreditor agreement.

          (i) For purposes of determining whether a Serviced Loan Combination
Change of Control Event has occurred, as well as the identity of the Serviced
Loan Combination Directing Lender, with respect to any Serviced A/B Loan
Combination, any Appraisal Reduction Amount that exists with respect thereto
shall be allocated: first, to the related Serviced Subordinate Non-Trust
Mortgage Loan (or any successor REO Mortgage Loan with respect thereto), up to
an aggregate amount equal to the then unpaid principal balance of such Serviced
Subordinate Non-Trust Mortgage Loan (or any successor REO Mortgage Loan with
respect thereto), together with all accrued and unpaid interest thereon (other
than Default Interest), and then, to the related Serviced Combination Trust
Mortgage Loan (or any successor REO Trust Mortgage Loan with respect thereto).

          (j) Notwithstanding anything herein to the contrary, if this Agreement
provides for obtaining a rating confirmation with respect to any Specially
Designated Non-Trust Mortgage Loan Securities in connection with any action
hereunder, no party hereto shall obtain such rating confirmation unless it is
reasonably assured that the cost of such rating confirmation (or the applicable
share thereof in accordance with the related Co-Lender Agreement) will be borne
(without right of reimbursement from the Trust) by the related Non-Trust
Mortgage Loan Securitization Trust or by another third party other than the
Trust.

     hereto), by a Serviced Non-Trust Mortgage Loan Noteholder (if affected
     thereby) or by the Holders of Certificates entitled to at least 25% of the
     Voting Rights, provided, however, that with respect to any such failure
     (other than a failure referred to in clause (v)(B) below) which is not
     curable within such 30-day (or, if applicable, 15-day) period, the Master
     Servicer or the Special Servicer, as the case may be, shall have an

     Servicer or the Special Servicer, as the case may be, has commenced to cure
     the subject failure within the initial 30-day (or, if applicable, 15-day)
     period and has provided the Trustee and any affected Serviced Non-Trust

     to the Trustee, the Depositor and each affected Serviced Non-Trust Mortgage
     Loan Noteholder the Annual Statement of Compliance, the Annual Assessment
     Report and the Annual Attestation Report (together with, if required to be
     filed with the Commission under applicable law, the related accountants'
     consent to filing thereof with the Commission) with respect to the Master
     Servicer (or any Additional Item 1123 Servicer or Sub-Servicing Function
     Participant, as applicable, retained or engaged thereby that is not
     identified on Exhibit K hereto) or the Special Servicer (or any Additional
     Item 1123 Servicer or Sub-Servicing Function Participant, as applicable,
     retained or engaged thereby), as applicable, pursuant to Section 3.13 or
     Section 3.14, as applicable, which is required to be part of or
     incorporated in a Subsequent Exchange Act Report required to be filed with

     may be, by or on behalf of any other party hereto in accordance with
     Section 3.13 or Section 3.14, as applicable, or (C) in the case of a
     failure to notify the Trustee and the Depositor that an Additional Item
     1123 Servicer or a Sub-Servicing Function Participant has been retained or

     30 days; or

               (vi) any breach on the part of the Master Servicer or the Special
     Servicer of any of its representations or warranties contained in this
     Agreement that materially and adversely affects the interests of any Class
     of Certificateholders or any Serviced Non-Trust Mortgage Loan Noteholder
     and which breach continues unremedied for a period of 30 days after the
     date on which written notice of such breach, requiring the same to be
     remedied, shall have been given to the Master Servicer or the Special
     Servicer, as the case may be, by any other party hereto or to the Master
     Servicer or the Special Servicer, as the case may be (with a copy to each
     other party hereto), by a Serviced Non-Trust Mortgage Loan Noteholder (if
     affected thereby) or by the Holders of Certificates entitled to at least
     25% of the Voting Rights, provided, however, that with respect to any such
     breach which is not curable within such 30-day period, the Master Servicer
     or the Special Servicer, as the case may be, shall have an additional cure
     period of 30 days so long as the Master Servicer or the Special Servicer,
     as the case may be, has commenced to cure such breach within the initial
     30-day period and has provided the Trustee and any affected Serviced
     Non-Trust Mortgage Loan Noteholder with an Officer's Certificate certifying
     that it has diligently pursued, and is diligently continuing to pursue, a
     full cure; or

               (vii) a decree or order of a court or agency or supervisory
     authority having jurisdiction in the premises in an involuntary case under
     any present or future federal or state bankruptcy, insolvency or similar
     law for the appointment of a conservator, receiver, liquidator, trustee or
     similar official in any bankruptcy, insolvency, readjustment of debt,
     marshaling of assets and liabilities or similar proceedings, or for the
     winding-up or liquidation of its affairs, shall have been entered against
     the Master Servicer or the Special Servicer and such decree or


                                     -327-



     order shall have remained in force undischarged, undismissed or unstayed
     for a period of 60 days; or

               (viii) the Master Servicer or the Special Servicer shall consent
     to the appointment of a conservator, receiver, liquidator, trustee or
     similar official in any bankruptcy, insolvency, readjustment of debt,
     marshaling of assets and liabilities or similar proceedings of or relating
     to it or of or relating to all or substantially all of its property; or

               (ix) the Master Servicer or the Special Servicer shall admit in
     writing its inability to pay its debts generally as they become due, file a
     petition to take advantage of any applicable bankruptcy, insolvency or

     creditors, voluntarily suspend payment of its obligations, or take any
     corporate action in furtherance of the foregoing; or

               (x) the Master Servicer or the Special Servicer is removed from
     S&P's Select Servicer List as a U.S. Commercial Mortgage Master Servicer or
     a U.S. Commercial Mortgage Special Servicer, as the case may be, and is not
     reinstated within 60 days, and the ratings of one or more Classes of
     Certificates or one or more classes of Specially Designated Non-Trust
     Mortgage Loan Securities by S&P are qualified, downgraded or withdrawn in
     connection with the removal; or

               (xi) a Servicing Officer of the Master Servicer or the Special
     Servicer, as the case may be, obtains actual knowledge that one or more
     ratings assigned by Moody's to the Certificates or to any Specially
     Designated Non-Trust Mortgage Loan Securities have been qualified,
     downgraded or withdrawn, or otherwise made the subject of a "negative"
     credit watch that remains in effect for at least 60 days, which action
     Moody's has determined, and provided notification in writing or
     electronically, including by public announcement, is solely or in material
     part a result of the Master Servicer or Special Servicer, as the case may
     be, acting in such capacity; or

               (xii) at any time that any Specially Designated Non-Trust
     Mortgage Loan Securities are rated by Fitch, the Master Servicer fails to
     be rated at least "CMS3" by Fitch as a master servicer or the Special
     Servicer fails to be rated at least "CSS3" by Fitch as a special servicer,
     and in either case that rating is not restored within 60 days after the
     subject downgrade or withdrawal; or

               (xiii) at any time that any Specially Designated Non-Trust
     Mortgage Loan Securities are rated by Fitch, one or more ratings assigned
     by Fitch to one or more classes of Specially Designated Non-Trust Mortgage
     Loan Securities have been qualified, downgraded or withdrawn, or otherwise
     made the subject of a "negative" credit watch that remains in effect for at
     least 60 days, which action Fitch has determined, and provided notification
     in writing or electronically, including by public announcement, is solely
     or in material part a result of the Master Servicer or Special Servicer, as
     the case may be, acting in such capacity.

          When a single entity acts as the Master Servicer and the Special
Servicer, an Event of Default in one capacity shall constitute an Event of
Default in the other capacity.


                                     -328-



          (b) If any Event of Default shall occur with respect to the Master
Servicer or the Special Servicer (in either case, for purposes of this Section
7.01(b), the "Defaulting Party") and shall be continuing, then, and in each and
every such case, so long as such Event of Default shall not have been remedied,
the Trustee may, and at the written direction of the Holders of Certificates
entitled to at least 25% of the Voting Rights, the Trustee shall, by notice in
writing to the Defaulting Party (with a copy of such notice to each other party
hereto and the Rating Agencies) terminate all of the rights and obligations (but
not the liabilities for actions and omissions occurring prior thereto) of the
Defaulting Party under this Agreement and in and to the Trust Fund and the
Serviced Non-Trust Mortgage Loans, other than its rights, if any, as a
Certificateholder hereunder or as the holder of any Serviced Non-Trust Mortgage
Loan or any interest therein; provided that the Master Servicer may not be
terminated solely for an Event of Default that affects only a Serviced Non-Trust
Mortgage Loan Noteholder or any class of Specially Designated Non-Trust Mortgage
Loan Securities (except that a Sub-Servicer may be appointed in accordance with
Section 7.01(d)); and provided, further, that, except as provided in Section
7.01(d), the Special Servicer may not be terminated solely for an Event of
Default that affects only a Serviced Non-Trust Mortgage Loan Noteholder or any
class of Specially Designated Non-Trust Mortgage Loan Securities. From and after
the receipt by the Defaulting Party of such written notice of termination,
subject to Section 7.01(c), all authority and power of the Defaulting Party
under this Agreement, whether with respect to the Certificates (other than as a
holder of any Certificate), the Trust Fund, the Serviced Non-Trust Mortgage
Loans (other than as a holder thereof or any interest therein) or otherwise,
shall pass to and be vested in the Trustee pursuant to and under this section,
and, without limitation, the Trustee is hereby authorized and empowered to
execute and deliver, on behalf of and at the expense of the Defaulting Party, as
attorney-in-fact or otherwise, any and all documents and other instruments, and
to do or accomplish all other acts or things necessary or appropriate to effect
the purposes of such notice of termination, whether to complete the transfer and
endorsement or assignment of the Trust Mortgage Loans, the Serviced Non-Trust
Mortgage Loans and related documents, or otherwise. The Master Servicer and the
Special Servicer each agree that, if it is terminated pursuant to this Section
7.01(b), it shall promptly (and in any event no later than ten (10) Business
Days subsequent to its receipt of the notice of termination) provide the Trustee
with all documents and records, including those in electronic form, requested
thereby to enable the Trustee to assume the Master Servicer's or Special
Servicer's, as the case may be, functions hereunder, and shall cooperate with
the Trustee in effecting the termination of the Master Servicer's or Special
Servicer's, as the case may be, responsibilities and rights hereunder, including
(i) if the Master Servicer is the Defaulting Party, the immediate transfer to
the Trustee or a successor Master Servicer for administration by it of all cash
amounts that shall at the time be or should have been credited by the Master
Servicer to a Custodial Account, the Collection Account, the Defeasance Deposit
Account, a Servicing Account or a Reserve Account or that are thereafter
received by or on behalf of it with respect to any Trust Mortgage Loan, any
Serviced Non-Trust Mortgage Loan or, to the extent it relates to the foregoing,
any REO Property or (ii) if the Special Servicer is the Defaulting Party, the
transfer within two (2) Business Days to the Trustee or a successor Special
Servicer for administration by it of all cash amounts that shall at the time be
or should have been credited by the Special Servicer to an REO Account, a
Custodial Account, a Servicing Account or a Reserve Account or should have been
delivered to the Master Servicer or that are thereafter received by or on behalf
of it with respect to any Trust Mortgage Loan, any Serviced Non-Trust Mortgage
Loan or, to the extent it relates to the foregoing, any REO Property; provided,
however, that the Master Servicer and the Special Servicer each shall, if
terminated pursuant to this Section 7.01(b), continue to be entitled to receive
all amounts accrued or owing to it under this Agreement on or prior to the date
of such termination, whether in respect of Advances or otherwise, and it shall
continue to be entitled to the benefits of Section 6.03 notwithstanding any such
termination. Any


                                     -329-



costs or expenses in connection with any actions to be taken by any party hereto
pursuant to this paragraph shall be borne by the Defaulting Party and if not
paid by the Defaulting Party within 90 days after the presentation of reasonable
documentation of such costs and expenses, such expense shall be reimbursed by
the Trust Fund; provided, however, that the Defaulting Party shall not thereby
be relieved of its liability for such expenses. For purposes of this Section
7.01 and also for purposes of Section 7.03(b), the Trustee shall not be deemed
to have knowledge of an event which constitutes, or which with the passage of
time or notice, or both, would constitute an Event of Default unless a
Responsible Officer of the Trustee assigned to and working in the Trustee's
Corporate Trust Office has actual knowledge thereof or unless notice of any
event which is in fact such an Event of Default is received by the Trustee and
such notice references the Certificates, the Trust Fund or this Agreement.

          (c) In the case of an Adverse Rating Event or prospective Adverse
Rating Event that has resulted in or may give rise to an Event of Default under
Section 7.01(a)(x), (xi), (xii) or (xiii) in respect of the Master Servicer or
the Special Servicer and of which the Trustee has notice, the Trustee shall,
promptly following its receipt of notice thereof, provide written notice thereof
to the Master Servicer or the Special Servicer, as applicable. Notwithstanding
Section 7.01(b), if the Master Servicer receives a notice of termination under
Section 7.01(b) solely due to an Event of Default under Section 7.01(a)(x),
(xi), (xii) or (xiii), and if the terminated Master Servicer provides the
Trustee with the appropriate "request for proposal" materials within five (5)
Business Days following such termination, then the Master Servicer shall
continue to serve in such capacity hereunder until a successor thereto is
selected in accordance with this Section 7.01(c) or the expiration of 45 days
from the Master Servicer's receipt of the notice of termination, whichever
occurs first. Upon receipt of such "request for proposal" materials from the
terminated Master Servicer, the Trustee shall promptly thereafter (using such
"request for proposal" materials) solicit good faith bids for the rights to
master service the Serviced Mortgage Loans and, to the extent applicable, the
Outside Serviced Trust Mortgage Loans under this Agreement from at least three
(3) Persons qualified to act as a successor Master Servicer hereunder in
accordance with Section 6.02 and Section 7.02 (any such Person so qualified, a
"Qualified Bidder") or, if three (3) Qualified Bidders cannot be located, then
from as many Persons as the Trustee can determine are Qualified Bidders;
provided that at the Trustee's request, the terminated Master Servicer shall
supply the Trustee with the names of Persons from whom to solicit such bids; and
provided, further, that the Trustee shall not be responsible if less than three
(3) or no Qualified Bidders submit bids for the right to master service the
Serviced Mortgage Loans and, to the extent applicable, the Outside Serviced
Trust Mortgage Loans under this Agreement. The bid proposal shall require any
Successful Bidder (as defined below), as a condition of such bid, to enter into
this Agreement as successor Master Servicer, and to agree to be bound by the
terms hereof, within 45 days after the receipt of notice of termination by the
terminated Master Servicer. The Trustee shall solicit bids on the basis of both:
(i) such successor Master Servicer (x) retaining all existing Sub-Servicers to
continue the primary servicing of the Serviced Mortgage Loans pursuant to the
terms of the respective Sub-Servicing Agreements and (y) entering into a
Sub-Servicing Agreement with the terminated Master Servicer under which the
terminated Master Servicer would sub-service each of the Serviced Mortgage Loans
not then subject to a Sub-Servicing Agreement at a sub-servicing fee rate per
annum equal to the related Master Servicing Fee Rate minus, in the case of each
Trust Mortgage Loan serviced, 0.01% per annum (each, a "Servicing-Retained
Bid"); and (ii) terminating each existing Sub-Servicing Agreement and
Sub-Servicer that it is permitted to terminate in accordance with Section 3.22
(each, a "Servicing-Released Bid"). The Trustee shall select the Qualified
Bidder with the highest cash Servicing-Retained Bid (or, if none, the highest
cash Servicing Released Bid) (the "Successful Bidder") to act as successor
Master Servicer hereunder. The Trustee shall direct the Successful Bidder to
enter into this Agreement as successor Master Servicer pursuant to the


                                     -330-



terms hereof (and, if the successful bid was a Servicing-Retained Bid, to enter
into a Sub-Servicing Agreement with the terminated Master Servicer as
contemplated above) no later than 45 days after the receipt of notice of
termination by the terminated Master Servicer.

          Upon the assignment and acceptance of the master servicing rights
hereunder to and by the Successful Bidder, the Trustee shall remit or cause to
be remitted (i) if the successful bid was a Servicing-Retained Bid, to the
terminated Master Servicer the amount of such cash bid received from the
Successful Bidder (net of "out-of-pocket" expenses incurred in connection with
obtaining such bid and transferring servicing) and (ii) if the successful bid
was a Servicing-Released Bid, to the Master Servicer and each terminated
Sub-Servicer its respective Bid Allocation.

          The terminated Master Servicer shall be responsible for all
out-of-pocket expenses incurred in connection with the attempt to sell its
rights to master service the Serviced Mortgage Loans and, to the extent
applicable, the Outside Serviced Trust Mortgage Loans, which expenses are not
reimbursed to the party that incurred such expenses pursuant to the preceding
paragraph.

          If the Successful Bidder has not entered into this Agreement as
successor Master Servicer within 45 days after the terminated Master Servicer
received written notice of termination or no Successful Bidder was identified
within such 45-day period, then the terminated Master Servicer shall reimburse
the Trustee for all reasonable "out-of-pocket" expenses incurred by the Trustee
in connection with such bid process and the Trustee shall have no further
obligations under this Section 7.01(c). The Trustee thereafter may act or may
select a successor to act as Master Servicer hereunder in accordance with
Section 7.02.

          (d) Notwithstanding Section 7.01(b) and Section 7.04: (1) if any Event
of Default on the part of the Master Servicer occurs that affects a Serviced
Non-Trust Mortgage Loan Noteholder or any class of Specially Designated
Non-Trust Mortgage Loan Securities, and if the Master Servicer is not otherwise
terminated in accordance with Section 7.01(b), then the Master Servicer may not
be terminated by or at the direction of the related Serviced Non-Trust Mortgage
Loan Noteholder; and (2) if any Event of Default on the part of the Master
Servicer occurs that affects solely a Serviced Non-Trust Mortgage Loan
Noteholder or any class of Specially Designated Non-Trust Mortgage Loan
Securities, then the Master Servicer may not be terminated by the Trustee;
provided, however, in the case of (1) or (2), at the request of such affected
Serviced Non-Trust Mortgage Loan Noteholder, subject to the terms of the related
Co-Lender Agreement, the Trustee shall require the Master Servicer to appoint,
within 30 days of the Trustee's request, a Sub-Servicer (or, if the related
Serviced Loan Combination is currently being sub-serviced, to replace, within 30
days of the Trustee's request, the then-current Sub-Servicer with a new
Sub-Servicer) with respect to the related Serviced Loan Combination. In
connection with the appointment of a Sub-Servicer in accordance with this
Section 7.01(d), the Master Servicer shall obtain, at its own expense, written
confirmation from each Rating Agency (and, if applicable, Fitch) that such
appointment will not result in an Adverse Rating Event with respect to any Class
of Certificates or, if the subject Serviced Loan Combination includes a
Specially Designated Securitized Non-Trust Mortgage Loan (or any successor REO
Mortgage Loan with respect thereto), any related class of Specially Designated
Non-Trust Mortgage Loan Securities rated by such rating agency. The related
Sub-Servicing Agreement shall provide that any Sub-Servicer appointed in
accordance with this Section 7.01(d) shall be responsible for all duties, and
shall be entitled to all compensation, of the Master Servicer under this
Agreement with respect to the subject Serviced Loan Combination, except that the
Master Servicer shall be entitled to retain that portion of the Master Servicing
Fee for the Trust


                                     -331-



Mortgage Loan or REO Trust Mortgage Loan included in the subject Serviced Loan
Combination that accrues at a rate equal to 0.01% per annum. Such Sub-Servicing
Agreement shall also provide that such Sub-Servicer shall agree to become the
master servicer under a separate servicing agreement (as contemplated by the
related Co-Lender Agreement) in the event that the subject Serviced Loan
Combination is no longer to be serviced and administered hereunder, which
separate servicing agreement shall contain servicing and administration,
limitation of liability, indemnification and servicing compensation provisions
substantially similar to the corresponding provisions of this Agreement, except
for the fact that the subject Serviced Loan Combination and the related
Mortgaged Property shall be the sole assets serviced and administered thereunder
and the sole source of funds thereunder. If any Sub-Servicer appointed in
accordance with this Section 7.01(d) shall at any time resign or be terminated,
then (subject to the related Co-Lender Agreement) the Master Servicer shall be
required to promptly appoint a substitute Sub-Servicer, which appointment shall
not result in an Adverse Rating Event with respect to any Class of Certificates
or, if the subject Serviced Loan Combination includes a Specially Designated
Securitized Non-Trust Mortgage Loan (or any successor REO Mortgage Loan with
respect thereto), any related class of Specially Designated Non-Trust Mortgage
Loan Securities rated by either Rating Agency or, if applicable, Fitch (as
evidenced in a writing obtained by the Master Servicer, at its own expense, from
each applicable rating agency). In the event that a successor Master Servicer is
acting hereunder and such successor Master Servicer desires to terminate the
Sub-Servicer appointed under this Section 7.01(d), the terminated Master
Servicer that was responsible for the Event of Default that led to the
appointment of such Sub-Servicer shall be responsible for all costs incurred in
connection with such termination, including the payment of any termination fee.

          Further notwithstanding Section 7.01(b) and Section 7.04, if any Event
of Default on the part of the Special Servicer occurs that affects a Serviced
Non-Trust Mortgage Loan Noteholder, and the Special Servicer is not otherwise
terminated in accordance with Section 7.01(b), then such Serviced Non-Trust
Mortgage Loan Noteholder may require the Trustee to terminate the duties and
obligations of the Special Servicer with respect to the related Serviced Loan
Combination only, but as to no other Serviced Mortgage Loan; and, in such event,
subject to any applicable consultation rights of any particular related Serviced
Non-Trust Mortgage Loan Noteholder under the related Co-Lender Agreement, the
appropriate party shall appoint in accordance with Section 6.09 (or, in the
event of the failure of such party to so appoint, the Trustee shall appoint in
accordance with Section 7.02), within 30 days of such Serviced Non-Trust
Mortgage Loan Noteholder's request, a replacement special servicer with respect
to the subject Serviced Loan Combination. In connection with the appointment of
a replacement special servicer with respect to the subject Serviced Loan
Combination at the request of a related Serviced Non-Trust Mortgage Loan
Noteholder in accordance with this Section 7.01(d), the Trustee shall obtain
written confirmation from each Rating Agency (and, if applicable, Fitch) that
such appointment will not result in an Adverse Rating Event with respect to any
Class of Certificates or, if the subject Serviced Loan Combination includes a
Specially Designated Securitized Non-Trust Mortgage Loan (or any successor REO
Mortgage Loan with respect thereto), any related class of Specially Designated
Non-Trust Mortgage Loan Securities rated by such rating agency (such rating
confirmation to be an expense of the terminated Special Servicer or, if not paid
thereby, an expense of the requesting Serviced Non-Trust Mortgage Loan
Noteholder). Any replacement special servicer appointed at the request of a
Serviced Non-Trust Mortgage Loan Noteholder in accordance with this Section
7.01(d) shall be responsible for all duties, and shall be entitled to all
compensation, of the Special Servicer under this Agreement with respect to the
subject Serviced Loan Combination. Any replacement special servicer appointed at
the request of a Serviced Non-Trust Mortgage Loan Noteholder in accordance with


                                     -332-



this Section 7.01(d) hereby agrees to become, upon request, the special servicer
under a separate servicing agreement (as contemplated by the related Co-Lender
Agreement) in the event that the subject Serviced Loan Combination is no longer
to be serviced and administered hereunder, which separate servicing agreement
shall contain servicing and administration, limitation of liability,
indemnification and servicing compensation provisions substantially similar to
the corresponding provisions of this Agreement, except for the fact that the
subject Serviced Loan Combination and the related Mortgaged Property shall be
the sole assets serviced and administered thereunder and the sole source of
funds thereunder. If any replacement special servicer appointed at the request
of a Serviced Non-Trust Mortgage Loan Noteholder in accordance with this Section
7.01(d) shall at any time resign or be terminated, then (subject to any
applicable consultation rights of any particular related Serviced Non-Trust
Mortgage Loan Noteholder under the related Co-Lender Agreement) the appropriate
party in accordance with Section 6.09 (or the Trustee in accordance with Section
7.02, if such party fails to do so) shall be required to promptly appoint a
substitute replacement special servicer, which appointment shall not result in
an Adverse Rating Event (as evidenced in writing by each Rating Agency and, if
applicable, Fitch) with respect to any Class of Certificates or, if the subject
Serviced Loan Combination includes a Specially Designated Securitized Non-Trust
Mortgage Loan, with respect to any related class of Specially Designated
Non-Trust Mortgage Loan Securities.

          In no event shall any waiver of an Event of Default pursuant to
Section 7.04 affect the rights of any Serviced Non-Trust Mortgage Loan
Noteholder under this Section 7.01(d).

          (e) If a Loan Combination/Loan-Specific Special Servicer is appointed
with respect to a Serviced Loan Combination or any related REO Property in
accordance with Section 7.01(d) or with respect to a Serviced Loan Combination,
a Split Trust Mortgage Loan or any related REO Property in accordance with
Section 6.09(d), such that there are multiple parties acting as Special Servicer
hereunder, then, unless the context clearly requires otherwise: (i) when used in
the context of imposing duties and obligations on the Special Servicer hereunder
or the performance of such duties and obligations, the term "Special Servicer"
shall mean the related Loan Combination/Loan-Specific Special Servicer, insofar
as such duties and obligations relate to a Serviced Loan Combination, a Split
Trust Mortgage Loan or any related REO Property as to which a Loan
Combination/Loan-Specific Special Servicer has been appointed, and shall mean
the General Special Servicer (as defined below), in all other cases (provided
that, in Section 3.13, Section 3.14 and Section 3.15, the term "Special
Servicer" shall mean each of the Loan Combination/Loan-Specific Special
Servicer(s) and the General Special Servicer); (ii) when used in the context of
identifying the recipient of any information, funds, documents, instruments
and/or other items, the term "Special Servicer" shall mean the related Loan
Combination/Loan-Specific Special Servicer, insofar as such information, funds,
documents, instruments and/or other items relate to a Serviced Loan Combination,
a Split Trust Mortgage Loan or any related REO Property as to which a Loan
Combination/Loan-Specific Special Servicer has been appointed, and shall mean
the General Special Servicer, in all other cases; (iii) when used in the context
of granting the Special Servicer the right to purchase Specially Serviced Trust
Mortgage Loans pursuant to Section 3.18, the term "Special Servicer" shall mean
the related Loan Combination/Loan-Specific Special Servicer, if such Specially
Serviced Trust Mortgage Loan is or is part of a Serviced Combination Trust
Mortgage Loan, a Split Trust Mortgage Loan or any related REO Property as to
which a Loan Combination/Loan-Specific Special Servicer has been appointed, and
shall mean the General Special Servicer, in all other cases; (iv) when used in
the context of granting the Special Servicer the right to purchase all of the
Trust Mortgage Loans and any REO Properties remaining in the Trust Fund pursuant
to Section 9.01, the term "Special Servicer" shall mean the General Special
Servicer only; (v) when used


                                     -333-



in the context of the Special Servicer being replaced, pursuant to Section
6.09(a), by the Majority Controlling Class Certificateholder(s), the term
"Special Servicer" shall mean the General Special Servicer or any Loan
Combination/Loan-Specific Special Servicer, as applicable, taking into account
the limitations of Section 6.09(d) (provided that no Loan Combination/Loan-
Specific Special Servicer can be succeeded by a Person that itself had been
replaced, pursuant to Section 7.01(d), as the Special Servicer with respect to
the subject Serviced Loan Combination); (vi) when used in the context of
granting the Special Servicer any protections, limitations on liability,
immunities and/or indemnities hereunder, the term "Special Servicer" shall mean
each of the Loan Combination/Loan-Specific Special Servicer(s) and the General
Special Servicer; and (vii) when used in the context of requiring
indemnification from, imposing liability on, or exercising any remedies against,
the Special Servicer for any breach of a representation, warranty or covenant
hereunder or for any negligence, bad faith or willful misconduct in the
performance of duties and obligations hereunder or any negligent disregard of
such duties and obligations or otherwise holding the Special Servicer
responsible for any of the foregoing, the term "Special Servicer" shall mean the
related Loan Combination/Loan-Specific Special Servicer or the General Special
Servicer, as applicable. References in this Section 7.01(e) to "General Special
Servicer" means the Person performing the duties and obligations of special
servicer with respect to the Mortgage Pool (exclusive of each Serviced Loan
Combination, Split Trust Mortgage Loan and related REO Property as to which a
Loan Combination/Loan-Specific Special Servicer has been appointed).

          (f) If, pursuant to the terms of any Outside Servicing Agreement under
which any Outside Serviced Trust Mortgage Loan or Administered REO Property is
being serviced and/or administered, an Outside Servicer Default has occurred
with respect to an Outside Servicer under such Outside Servicing Agreement and
remains unremedied, then the Trustee may, if materially and adversely affected
in its capacity as holder of such Outside Serviced Trust Mortgage Loan or any
successor REO Trust Mortgage Loan with respect thereto, to the fullest extent
permitted by such Outside Servicing Agreement, either (i) waive such Outside
Servicer Default (but only if directed to do so in accordance with Section
7.04), or (ii) absent such waiver, direct the appropriate party under such
Outside Servicing Agreement to exercise such remedies thereunder regarding the
termination and replacement of, or the appointment of a new subservicer to
perform the duties of, the Outside Servicer as to which such Outsider Servicer
Default relates. In connection with the foregoing, the Trustee may (and, at the
direction of the Controlling Class Representative or the Holders of Certificates
entitled to at least 25% of the Voting Rights, is required to) exercise the
rights set forth in clause (ii) of the preceding sentence as the Holder of the
subject Outside Serviced Trust Mortgage Loan or any successor REO Trust Mortgage
Loan with respect thereto; and, furthermore, if and to the extent necessary, the
Trustee shall contact and act with the other applicable Non-Trust Mortgage Loan
Noteholders in exercising such rights.

          SECTION 7.02.  Trustee to Act; Appointment of Successor.

          On and after the time the Master Servicer or the Special Servicer
resigns pursuant to Section 6.04 or receives a notice of termination pursuant to
Section 7.01, the Trustee shall, unless and until a successor is appointed
pursuant to Section 6.04, Section 6.09, Section 7.01(c) or Section 7.01(d), be
the successor in all respects to the Master Servicer or the Special Servicer, as
the case may be, in its capacity as such under this Agreement and the
transactions set forth or provided for herein and shall have all (and the former
Master Servicer or the Special Servicer, as the case may be, shall cease to have
any) of the responsibilities, duties and liabilities of the Master Servicer or
the Special Servicer, as the


                                     -334-



case may be, arising thereafter, including, if the Master Servicer is the
resigning or terminated party, the Master Servicer's obligation to make P&I
Advances, including in connection with any termination of the Master Servicer
for an Event of Default described in clause 7.01(a)(iii), the unmade P&I
Advances that gave rise to such Event of Default; provided that any failure to
perform such duties or responsibilities caused by the Master Servicer's or the
Special Servicer's, as the case may be, failure to provide information or monies
required by Section 7.01 shall not be considered a default by the Trustee
hereunder. The Trustee shall not be liable for any of the representations and
warranties of the resigning or terminated party or for any losses incurred by
the resigning or terminated party pursuant to Section 3.06 hereunder nor shall
the Trustee be required to purchase any Mortgage Loan hereunder. As compensation
therefor, subject to the last sentence of the second paragraph of Section
3.11(c), the Trustee shall be entitled to all fees and other compensation which
the resigning or terminated party would have been entitled to if the resigning
or terminated party had continued to act hereunder.

          Notwithstanding the above, the Trustee may, if it shall be unwilling
to so act as either Master Servicer or Special Servicer, as the case may be, or
shall, if it is unable to so act as either Master Servicer or Special Servicer,
as the case may be, or if the Trustee is not approved as a master servicer or a
special servicer, as the case may be, by any of the Rating Agencies, or if the
Holders of Certificates entitled to a majority of the Voting Rights so request
in writing to the Trustee, promptly appoint (subject, in the case of a resigning
or terminated Special Servicer, to any applicable consultation rights of any
particular related Serviced Non-Trust Mortgage Loan Noteholder(s) under the
related Co-Lender Agreement), or petition a court of competent jurisdiction to
appoint, any established mortgage loan servicing institution as the successor to
the resigning or terminated Master Servicer or the Special Servicer, as the case
may be, hereunder in the assumption of all or any part of the responsibilities,
duties or liabilities of the resigning or terminated Master Servicer or the
Special Servicer, as the case may be, hereunder; provided, however, that no such
appointee shall succeed to the rights and obligations of the Master Servicer or
Special Servicer hereunder unless (i) as confirmed in writing by each Rating
Agency and, if applicable, by Fitch, such succession will not result in an
Adverse Rating Event with respect to any Class of Certificates or any class of
Specially Designated Non-Trust Mortgage Loan Securities rated by such rating
agency, and (ii) such appointee makes the applicable representations and
warranties set forth in Section 3.23 or Section 3.24, as applicable; and
provided, further, that in the case of a resigning or terminated Special
Servicer, such appointment shall be subject to the rights of the Majority
Controlling Class Certificateholder(s) to designate a successor pursuant to
Section 6.09. No appointment of a successor to the Master Servicer or the
Special Servicer hereunder shall be effective until the assumption by the
successor to such party of all its responsibilities, duties and liabilities
under this Agreement. Pending appointment of a successor to the Master Servicer
or the Special Servicer hereunder, the Trustee shall act in such capacity as
hereinabove provided. In connection with any such appointment and assumption
described herein, the Trustee may make such arrangements for the compensation of
such successor out of payments on the Serviced Mortgage Loans and the
Administered REO Properties as it and such successor shall agree, subject to the
terms of this Agreement and/or the related Co-Lender Agreement limiting the use
of funds received in respect of a Serviced Loan Combination to matters related
to such Loan Combination; provided, however, that no such compensation shall be
in excess of that permitted the resigning or terminated party hereunder. Such
successor and the other parties hereto shall take such action, consistent with
this Agreement, as shall be necessary to effectuate any such succession.


                                     -335-



          SECTION 7.03.  Notification to Certificateholders and Others.

          (a) Upon any resignation of the Master Servicer or the Special
Servicer pursuant to Section 6.04, any termination of the Master Servicer or the
Special Servicer pursuant to Section 7.01, any appointment of a successor to the
Master Servicer or the Special Servicer pursuant to Section 7.02 or the
effectiveness of any designation of a new Special Servicer pursuant to Section
6.09, the Trustee shall give prompt written notice thereof to the Depositor, to
the Certificateholders at their respective addresses appearing in the
Certificate Register and to each Serviced Non-Trust Mortgage Loan Noteholder.
Not later than ten days (or, in the case of notice to the Depositor, as soon as
reasonably practicable) after a Responsible Officer of the Trustee has received
notice of the occurrence of any resignation, termination or replacement of, or
appointment of a successor to, any Outside Servicer pursuant to the related
Outside Servicing Agreement, the Trustee shall give written notice of such event
to the Depositor and the Certificateholders.

          (b) Not later than 10 days (or, in the case of notice to the
Depositor, as soon as reasonably practicable) after a Responsible Officer of the
Trustee has notice of the occurrence of any event which constitutes or, with
notice or lapse of time or both, would constitute an Event of Default or an
Outside Servicer Default, the Trustee shall promptly notify in writing the
Depositor, all the Certificateholders and the Rating Agencies notice of such
occurrence, unless such default shall have been cured.

          SECTION 7.04.  Waiver of Events of Default and Outside Servicer
                         Defaults.

          The Holders representing at least 66-2/3% of the Voting Rights
allocated to each Class of Certificates affected by any Event of Default
hereunder or any Outside Servicer Default under an Outside Servicing Agreement
may waive such Event of Default or direct the Trustee, to the extent it is
permitted to do so under the applicable Outside Servicing Agreement, to waive
such Outside Servicer Default, as the case may be; provided, however, that (A)
an Event of Default under any of clauses (i), (ii), (iii), (x) and (xi) of
Section 7.01(a) or any comparable Outside Servicer Default may be waived only by
all of the Certificateholders of the affected Classes, (B) waiver of an Event of
Default under clause (iii) of Section 7.01(a) further requires the written
consent of the Trustee and (C) waiver of an Event of Default contemplated by
clause (B) or clause (C) of Section 7.01(a)(v) may only be waived with the
consent of the Depositor. Upon any such waiver of an Event of Default or an
Outside Servicer Default, such Event of Default or, to the extent it is in fact
waived under the applicable Outside Servicing Agreement, such Event of Default
or such Outside Servicer Default, as the case may be, shall cease to exist and
shall be deemed to have been remedied for every purpose hereunder (except as
otherwise provided in Section 7.01(d)). No such waiver shall extend to any
subsequent or other Event of Default or Outside Servicer Default, as the case
may be, or impair any right consequent thereon except to the extent expressly so
waived. Notwithstanding any other provisions of this Agreement, for purposes of
waiving any Event of Default or Outside Servicer Default pursuant to this
Section 7.04, Certificates registered in the name of the Depositor or any
Affiliate of the Depositor shall be entitled to Voting Rights with respect to
the matters described above.

          SECTION 7.05.  Additional Remedies of Trustee Upon Event of Default or
                         Outside Servicer Default.

          During the continuance of any Event of Default or Outside Servicer
Default that shall not have been remedied, the Trustee, in addition to the
rights specified in Section 7.01, shall have the right,


                                     -336-



in its own name and as trustee of an express trust and on behalf of any Serviced
Non-Trust Mortgage Loan Noteholder, to take all actions now or hereafter
existing at law, in equity or by statute to enforce its rights and remedies and
to protect the interests, and enforce the rights and remedies, of the
Certificateholders and the Serviced Non-Trust Mortgage Loan Noteholders
(including the institution and prosecution of all judicial, administrative and
other proceedings and the filings of proofs of claim and debt in connection
therewith). Except as otherwise expressly provided in this Agreement, no remedy
provided for by this Agreement shall be exclusive of any other remedy, and each
and every remedy shall be cumulative and in addition to any other remedy, and no
delay or omission to exercise any right or remedy shall impair any such right or
remedy or shall be deemed to be a waiver of any Event of Default or Outside
Servicer Default.


                                     -337-



                                  ARTICLE VIII

                             CONCERNING THE TRUSTEE

          SECTION 8.01.  Duties of Trustee.

          (a) The Trustee, prior to the occurrence of an Event of Default or an
Outside Servicer Default and after the curing or waiver of all Events of Default
and all Outside Servicer Defaults that may have occurred, undertakes to perform
such duties and only such duties as are specifically set forth in this
Agreement. If an Event of Default or an Outside Servicer Default occurs and is
continuing, the Trustee shall exercise such of the rights and powers vested in
it by this Agreement, and use the same degree of care and skill in their
exercise as a prudent man would exercise or use under the circumstances in the
conduct of his own affairs; provided that if the Trustee is acting as Master
Servicer or Special Servicer, it shall act in accordance with the Servicing
Standard. Any permissive right of the Trustee contained in this Agreement shall
not be construed as a duty.

          (b) The Trustee, upon receipt of all resolutions, certificates,
statements, opinions, reports, documents, orders or other instruments furnished
to the Trustee that are specifically required to be furnished pursuant to any
provision of this Agreement (other than the Mortgage Files, the review of which
is specifically governed by the terms of Article II), shall examine them to
determine whether they conform to the requirements of this Agreement. If any
such instrument is found not to conform to the requirements of this Agreement in
a material manner, the Trustee shall take such action as it deems appropriate to
have the instrument corrected. The Trustee shall not be responsible for the
accuracy or content of any resolution, certificate, statement, opinion, report,
document, order or other instrument furnished by the Depositor, the Master
Servicer or the Special Servicer, and accepted by the Trustee in good faith,
pursuant to this Agreement.

          (c) No provision of this Agreement shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act or its own misconduct; provided, however, that:

               (i) Prior to the occurrence of an Event of Default or an Outside
     Servicer Default, and after the curing of all such Events of Default and
     all such Outside Servicer Defaults that may have occurred, the duties and
     obligations of the Trustee shall be determined solely by the express
     provisions of this Agreement, the Trustee shall not be liable except for
     the performance of such duties and obligations as are specifically set
     forth in this Agreement, no implied covenants or obligations shall be read
     into this Agreement against the Trustee and, in the absence of bad faith on
     the part of the Trustee, the Trustee may conclusively rely, as to the truth
     of the statements and the correctness of the opinions expressed therein,
     upon any certificates or opinions furnished to the Trustee and conforming
     to the requirements of this Agreement;

               (ii) The Trustee shall not be personally liable for an error of
     judgment made in good faith by a Responsible Officer or Responsible
     Officers of the Trustee, unless it shall be proved that the Trustee was
     negligent in ascertaining the pertinent facts;

               (iii) The Trustee shall not be personally liable with respect to
     any action taken, suffered or omitted to be taken by it in good faith in
     accordance with the terms of this


                                      -338-



     Agreement and the direction of the Controlling Class or Holders of
     Certificates entitled to at least 25% of the Voting Rights, relating to the
     time, method and place of conducting any proceeding for any remedy
     available to the Trustee, or exercising any trust or power conferred upon
     the Trustee, under this Agreement or, as holder of an Outside Serviced
     Trust Mortgage Loan (or any successor REO Trust Mortgage Loan with respect
     thereto), under an Outside Servicing Agreement, as the case may be; and

               (iv) The protections, immunities and indemnities afforded to the
     Trustee hereunder shall also be available to it in its capacity as
     Authenticating Agent, Certificate Registrar, Tax Administrator and
     Custodian.

          SECTION 8.02.  Certain Matters Affecting Trustee.

          Except as otherwise provided in Section 8.01 and Article X:

               (i) the Trustee may rely upon and shall be protected in acting or
     refraining from acting upon any resolution, Officer's Certificate,
     certificate of auditors or any other certificate, statement, instrument,
     opinion, report, notice, request, consent, order, appraisal, bond or other
     paper or document reasonably believed by it to be genuine and to have been
     signed or presented by the proper party or parties;

               (ii) the Trustee may consult with counsel and the written advice
     of such counsel or any Opinion of Counsel shall be full and complete
     authorization and protection in respect of any action taken or suffered or
     omitted by it hereunder in good faith and in accordance therewith;

               (iii) the Trustee shall be under no obligation to exercise any of
     the trusts or powers vested in it by this Agreement or to make any
     investigation of matters arising hereunder or, except as provided in
     Section 10.01 or 10.02, to institute, conduct or defend any litigation
     hereunder or in relation hereto, at the request, order or direction of any
     of the Certificateholders, pursuant to the provisions of this Agreement,
     unless such Certificateholders shall have offered to the Trustee reasonable
     security or indemnity against the costs, expenses and liabilities which may
     be incurred therein or thereby; except as provided in Section 10.01 or
     10.02, the Trustee shall not be required to expend or risk its own funds or
     otherwise incur any financial liability in the performance of any of its
     duties hereunder, or in the exercise of any of its rights or powers, if it
     shall have reasonable grounds for believing that repayment of such funds or
     adequate indemnity against such risk or liability is not reasonably assured
     to it; nothing contained herein shall, however, relieve the Trustee of the
     obligation, upon the occurrence of an Event of Default or an Outside
     Servicer Default that has not been cured, to exercise such of the rights
     and powers vested in it by this Agreement, and to use the same degree of
     care and skill in their exercise as a prudent man would exercise or use
     under the circumstances in the conduct of his own affairs;

               (iv) the Trustee shall not be personally liable for any action
     reasonably taken, suffered or omitted by it in good faith and believed by
     it to be authorized, or within the discretion or rights or powers conferred
     upon it, by this Agreement;

               (v) prior to the occurrence of an Event of Default or an Outside
     Servicer Default, and after the curing of all Events of Default and all
     Outside Servicer Defaults that may


                                     -339-



     have occurred, and except as may be provided in Section 10.01 or 10.02, the
     Trustee shall not be bound to make any investigation into the facts or
     matters stated in any resolution, certificate, statement, instrument,
     opinion, report, notice, request, consent, order, approval, bond or other
     paper or document, unless requested in writing to do so by Holders of
     Certificates entitled to at least 25% of the Voting Rights; provided,
     however, that if the payment within a reasonable time to the Trustee of the
     costs, expenses or liabilities likely to be incurred by it in the making of
     such investigation is, in the opinion of the Trustee, not reasonably
     assured to the Trustee by the security afforded to it by the terms of this
     Agreement, the Trustee may require reasonable indemnity against such
     expense or liability as a condition to taking any such action;

               (vi) the Trustee may execute any of the trusts or powers
     hereunder or perform any duties hereunder either directly or by or through
     agents or attorneys; provided, however, that the Trustee shall remain
     responsible for all acts and omissions of such agents or attorneys within
     the scope of their employment to the same extent as it is responsible for
     its own actions and omissions hereunder; and provided, further, that,
     unless and until the Trustee has filed a Form 15 with respect to the Trust
     in accordance with Section 8.15, the Trustee may not engage any such agent
     or attorney-in-fact that would constitute an Additional Item 1123 Servicer
     or a Sub-Servicing Function Participant, unless it first obtains the
     written consent of the Depositor; and

               (vii) the Trustee shall not be responsible for any act or
     omission of the Master Servicer or the Special Servicer (unless the Trustee
     is acting as Master Servicer or Special Servicer) or the Depositor.

          SECTION 8.03.  Trustee and Fiscal Agent Not Liable for Validity or
                         Sufficiency of Certificates or Mortgage Loans.

          The recitals contained herein and in the Certificates, other than the
statements attributed to the Trustee or any Fiscal Agent in Article II and
Section 8.16 and Section 8.18 and the signature of the Certificate Registrar and
the Authenticating Agent set forth on each outstanding Certificate, shall not be
taken as the statements of the Trustee or such Fiscal Agent, and neither the
Trustee nor such Fiscal Agent shall assume any responsibility for their
correctness. Except as expressly set forth in Section 8.16 and 8.18, neither the
Trustee nor any Fiscal Agent makes any representations as to the validity or
sufficiency of this Agreement or of any Certificate (other than as to the
signature of the Trustee set forth thereon) or of any Mortgage Loan or related
document. Neither the Trustee nor any Fiscal Agent shall be accountable for the
use or application by the Depositor of any of the Certificates issued to it or
of the proceeds of such Certificates, or for the use or application of any funds
paid to the Depositor in respect of the assignment of the Trust Mortgage Loans
to the Trust Fund, or any funds deposited in or withdrawn from a Custodial
Account or any other account by or on behalf of the Depositor, the Master
Servicer or the Special Servicer. Neither the Trustee nor any Fiscal Agent shall
be responsible for the accuracy or content of any resolution, certificate,
statement, opinion, report, document, order or other instrument furnished by the
Depositor, the Master Servicer or the Special Servicer, and accepted by the
Trustee in good faith, pursuant to this Agreement.


                                     -340-



          SECTION 8.04.  Trustee and Fiscal Agent May Own Certificates.

          The Trustee, any Fiscal Agent or any agent of the Trustee or a Fiscal
Agent, in its individual or any other capacity, may become the owner or pledgee
of Certificates with (except as otherwise provided in the definition of
"Certificateholder") the same rights it would have if it were not the Trustee,
such Fiscal Agent or such agent, as the case may be.

          SECTION 8.05.  Fees and Expenses of Trustee; Indemnification of and by
                         Trustee.

          (a) On each Distribution Date, the Trustee shall withdraw from the
general funds on deposit in the Collection Account, prior to any distributions
to be made therefrom on such date, and pay to itself the Trustee Fee for such
Distribution Date and, to the extent not previously paid, for all prior
Distribution Dates, as compensation for all services rendered by the Trustee in
the execution of the trusts hereby created and in the exercise and performance
of any of the powers and duties of the Trustee hereunder. Except as otherwise
provided in Section 3.06, the Trustee Fees (which shall not be limited by any
provision of law in regard to the compensation of a trustee of an express trust)
shall constitute the Trustee's sole compensation for such services to be
rendered by it.

          (b) The Trustee (whether in its individual capacity or its capacity as
Trustee) and any director, officer, employee or agent of the Trustee shall be
entitled to be indemnified for and held harmless by the Trust Fund out of the
Pool Custodial Account and the Collection Account (and, to the extent that a
Serviced Loan Combination or any related REO Property is affected, by the Trust
Fund and/or the related Serviced Non-Trust Mortgage Loan Noteholder(s) out of
the related Loan Combination Custodial Account) against any loss, liability or
reasonable "out-of-pocket" expense arising out of, or incurred in connection
with, this Agreement or the Certificates (including (i) costs and expenses
incurred in connection with removal of the Special Servicer and Master Servicer
pursuant to Sections 7.01 and 7.02, (ii) costs and expenses of litigation and of
investigation, including counsel fees, damages, judgments and amounts paid in
settlement, and (iii) costs and expenses of mediation and/or arbitration
pursuant to Section 2.03(i) hereof or Section 5(i) of the UBS/Depositor Mortgage
Loan Purchase Agreement) (any such loss, liability or expense, a "Trustee
Liability"); provided that such loss, liability or expense constitutes an
"unanticipated expense" within the meaning of Treasury regulations section
1.860G-1(b)(3)(ii); and provided, further, that neither the Trustee nor any of
the other above specified Persons shall be entitled to indemnification pursuant
to this Section 8.05(b) for (1) any liability specifically required to be borne
thereby pursuant to the terms of this Agreement, or (2) any loss, liability or
expense incurred by reason of willful misfeasance, bad faith or negligence in
the performance of, or the negligent disregard of, the Trustee's obligations and
duties hereunder, or as may arise from a breach of any representation, warranty
or covenant of the Trustee made herein, or (3) any loss, liability or expense
that constitutes an Advance (the reimbursement of which has otherwise been
provided for herein) or allocable overhead. The provisions of this Section
8.05(b) and of Section 8.05(c) shall survive any resignation or removal of the
Trustee and appointment of a successor trustee.

          (c) If the Trustee Liability arises from the issuance or sale of the
Certificates and the indemnification provided for in Section 8.05(b) is invalid
or unenforceable, then the Trust Fund shall contribute to the amount paid or
payable by the Trustee as a result of such Trustee Liability in such proportion
as is appropriate to reflect the relative fault of any of the other parties on
the one hand and the Trustee on the other in connection with the actions or
omissions which resulted in such Trustee Liability, as well as any other
relevant equitable considerations.


                                     -341-



          (d) The Trustee shall indemnify and hold harmless the Trust Fund
against any losses arising out of any errors made solely by the Trustee in
calculating distributions to be made hereunder and any other calculation or
reporting hereunder (in each case not attributable to information provided to
the Trustee by the Master Servicer or the Special Servicer); provided that such
loss arose by reason of willful misfeasance, bad faith or negligence on the part
of the Trustee. The provisions of this Section 8.05(d) shall survive any
resignation or removal of the Trustee and appointment of a successor trustee.

          SECTION 8.06.  Eligibility Requirements for Trustee.

          (a) The Trustee hereunder shall at all times be a bank, a trust
company, a banking association or a banking corporation organized and doing
business under the laws of the United States of America or any state thereof or
the District of Columbia, authorized under such laws to exercise trust powers,
having a combined capital and surplus of at least $50,000,000 and subject to
supervision or examination by federal or state banking authority. If such bank,
trust company, banking association or banking corporation publishes reports of
condition at least annually, pursuant to law or to the requirements of the
aforesaid supervising or examining authority, then for the purposes of this
section the combined capital and surplus of such bank, trust company, banking
association or banking corporation shall be deemed to be its combined capital
and surplus as set forth in its most recent report of condition so published.
The Trustee shall at all times maintain a long-term unsecured debt rating of at
least (i) "AA-" from S&P (or "A+" from S&P, if the Trustee's short-term
unsecured debt rating is at least "A-1" by S&P) and "Aa3" from Moody's or, if a
Fiscal Agent meeting the requirements of Section 8.17(a) is then currently
acting in such capacity, "A-" from S&P and "A3" from Moody's, or (ii) in the
case of either Rating Agency, such other rating as shall not result in an
Adverse Rating Event with respect to any Class of Certificates, as confirmed in
writing by such Rating Agency. The Trustee shall at all times satisfy the
requirements of Section 26(a)(1) of the Investment Company Act of 1940, as
amended. The Trustee's acting in such capacity shall not adversely affect the
application of the Prohibited Transaction Exemption to the Investment Grade
Certificates. If at any time the Trustee shall cease to be eligible in
accordance with the provisions of this section, the Trustee shall resign
immediately in the manner and with the effect specified in Section 8.07;
provided that the Trustee shall not be required to resign due to the existence
of an affiliation described in the last sentence of this Section 8.06 until such
time as it has actual knowledge or receives written notice of the existence of
such affiliation; and provided, further, that if the Trustee shall cease to be
so eligible because its combined capital and surplus is no longer at least
$50,000,000 or its long-term unsecured debt rating no longer conforms to the
requirements of the immediately preceding sentence, and if the Trustee proposes
to the other parties hereto to enter into an agreement with (and reasonably
acceptable to) each of them, and if in light of such agreement the Trustee's
continuing to act in such capacity would not (as evidenced in writing by each
Rating Agency) cause an Adverse Rating Event with respect to any Class of
Certificates, then upon the execution and delivery of such agreement the Trustee
shall not be required to resign, and may continue in such capacity, for so long
as none of the ratings assigned by the Rating Agencies to the Certificates is
adversely affected thereby. The bank, trust company, banking corporation or
banking association serving as Trustee may have normal banking and trust
relationships with the Depositor, the Master Servicer, the Special Servicer and
their respective Affiliates. Notwithstanding the foregoing, except to the extent
permitted or required by Section 7.02, the Trustee shall not be an "affiliate"
(as such term is defined in Section III of PTE 2000-58) of the Master Servicer,
the Special Servicer, any Sub-Servicer, any Outside Servicer, the Depositor, or
any obligor with respect to Trust Mortgage Loans constituting more than 5% of
the aggregate unamortized principal balance of the Mortgage Pool as of the
Closing Date or any "affiliate" (as such term is defined in Section III of PTE
2000-58) of any such Person.


                                     -342-



          SECTION 8.07.  Resignation and Removal of Trustee.

          (a) The Trustee may at any time resign and be discharged from the
trusts hereby created by giving written notice thereof to the Depositor, the
Master Servicer, the Special Servicer, all Certificateholders and all Serviced
Non-Trust Mortgage Loan Noteholders. Upon receiving such notice of resignation,
the Depositor shall promptly appoint a successor trustee acceptable to the
Depositor by written instrument, in duplicate, which instrument shall be
delivered to the resigning Trustee and to the successor trustee. A copy of such
instrument shall be delivered to the Master Servicer, the Special Servicer, the
Certificateholders and the Serviced Non-Trust Mortgage Loan Noteholders by the
Depositor. If no successor trustee shall have been so appointed and have
accepted appointment within 30 days after the giving of such notice of
resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor trustee.

          (b) If at any time the Trustee shall cease to be eligible in
accordance with the provisions of Section 8.06 and shall fail to resign after
written request therefor by the Depositor, or if at any time the Trustee shall
become incapable of acting, or shall be adjudged bankrupt or insolvent, or a
receiver of the Trustee or of its property shall be appointed, or any public
officer shall take charge or control of the Trustee or of its property or
affairs for the purpose of rehabilitation, conservation or liquidation, or if
the Trustee shall fail (other than by reason of the failure of either the Master
Servicer or the Special Servicer to timely perform its obligations hereunder or
as a result of other circumstances beyond the Trustee's reasonable control) to
timely deliver or otherwise make available in accordance with this Agreement any
current or revised Distribution Date Statement, CMSA Loan Periodic Update File,
CMSA Property File, CMSA Financial File or other report or statement required by
Section 4.02 and such failure shall continue unremedied for a period of five
days after receipt of written notice by the Trustee of such failure, or if the
Trustee shall fail (other than by reason of the failure of the Master Servicer,
the Special Servicer or the Depositor or any Sub-Servicer, subcontractor, vendor
or agent of the foregoing to timely perform its obligations hereunder or in
connection herewith or as a result of other circumstances beyond the Trustee's
reasonable control) to timely perform any of its obligations set forth in
Section 3.13, Section 3.14 or Section 8.15(a) and such failure adversely affects
the Depositor's ability to use or file a registration statement on Form S-3 for
purposes of publicly offering commercial mortgage-backed securities, or if a tax
is imposed or threatened with respect to the Trust Fund by any state in which
the Trustee is located or in which it holds any portion of the Trust Fund, then
the Depositor may remove the Trustee and appoint a successor trustee acceptable
to the Depositor and the Master Servicer by written instrument, in duplicate,
which instrument shall be delivered to the Trustee so removed and to the
successor trustee. A copy of such instrument shall be delivered to the Master
Servicer, the Special Servicer, the Certificateholders and the Serviced
Non-Trust Mortgage Loan Noteholders by the successor trustee so appointed.

          (c) The Holders of Certificates entitled to at least 51% of the Voting
Rights may at any time remove the Trustee (with or without cause) and appoint a
successor trustee by written instrument or instruments, signed by such Holders
or their attorneys-in-fact duly authorized, one complete set of which
instruments shall be delivered to the Master Servicer, one complete set to the
Trustee so removed and one complete set to the successor trustee so appointed. A
copy of such instrument shall be delivered to the Depositor, the Special
Servicer, the remaining Certificateholders and the Serviced Non-Trust Mortgage
Loan Noteholders by the successor trustee so appointed.


                                     -343-



          (d) In the event that the Trustee is terminated or removed pursuant to
this Section 8.07, all of its and any corresponding Fiscal Agent's rights and
obligations under this Agreement and (as among the parties hereto) in and to the
Trust Mortgage Loans and the Serviced Non-Trust Mortgage Loans shall be
terminated, other than (i) any rights or obligations that accrued prior to the
date of such termination or removal (including the right to receive all fees,
expenses and other amounts (including P&I Advances and any accrued interest
thereon) accrued or owing to it under this Agreement, with respect to periods
prior to the date of such termination or removal, and no termination without
cause shall be effective until the payment of such amounts to the Trustee and
such Fiscal Agent) or (ii) any rights or immunities described in this Agreement
as surviving any resignation or removal of the Trustee, including but not
limited to the rights set forth in Sections 8.05(b) and (c).

          (e) Any resignation or removal of the Trustee and appointment of a
successor trustee pursuant to any of the provisions of this Section 8.07 shall
not become effective until acceptance of appointment by the successor trustee as
provided in Section 8.08.

          SECTION 8.08.  Successor Trustee.

          (a) Any successor trustee appointed as provided in Section 8.07 shall
execute, acknowledge and deliver to the Depositor, the Master Servicer, the
Special Servicer and to the predecessor trustee an instrument accepting such
appointment hereunder and thereupon the resignation or removal of the
predecessor trustee shall become effective and such successor trustee, without
any further act, deed or conveyance, shall become fully vested with all the
rights, powers, duties and obligations of its predecessor hereunder, with the
like effect as if originally named as trustee herein. The predecessor trustee
shall deliver to the successor trustee all Mortgage Files and related documents
and statements and moneys held by it hereunder (other than any Mortgage Files at
the time held on its behalf by a third-party Custodian, which Custodian shall
become the agent of the successor trustee), and the Depositor, the Master
Servicer, the Special Servicer and the predecessor trustee shall execute and
deliver such instruments and do such other things as may reasonably be required
to more fully and certainly vest and confirm in the successor trustee all such
rights, powers, duties and obligations, and to enable the successor trustee to
perform its obligations hereunder.

          (b) No successor trustee shall accept appointment as provided in this
Section 8.08, unless at the time of such acceptance such successor trustee shall
be eligible under the provisions of Section 8.06.

          (c) Upon acceptance of appointment by a successor trustee as provided
in this Section 8.08, such successor trustee shall mail notice of the succession
of such trustee hereunder to the Depositor, the Master Servicer, the Special
Servicer, the Certificateholders and the Serviced Non-Trust Mortgage Loan
Noteholders.

          (d) Any and all costs and expenses associated with transferring the
duties of a Trustee that has resigned or been removed or terminated, as
contemplated by Section 8.07, to a successor Trustee, including those associated
with transfer of the Mortgage Files and other documents and statements held by
the predecessor Trustee to the successor Trustee, as contemplated by Section
8.08(a), shall be paid by: (i) the predecessor Trustee, if such predecessor
Trustee has resigned in accordance with Section 8.07(a), has been removed in
accordance with Section 8.07(b) or has been removed with cause in accordance
with Section 8.07(c); (ii) the Certificateholders that effected the removal, if
the predecessor Trustee has been removed without cause in accordance with
Section 8.07(c); and (iii) the


                                     -344-



Trust, if such costs and expenses are not paid by the predecessor Trustee or the
subject Certificateholders, as contemplated by the immediately preceding clauses
(i) and (ii), within 90 days after they are incurred (provided that such
predecessor Trustee or such subject Certificateholders, as applicable, shall
remain liable to the Trust for such costs and expenses).

          SECTION 8.09.  Merger or Consolidation of Trustee and Fiscal Agent.

          Any entity into which the Trustee or any Fiscal Agent may be merged or
converted, or with which the Trustee or any Fiscal Agent may be consolidated, or
any entity resulting from any merger, conversion or consolidation to which the
Trustee or any Fiscal Agent shall be a party, or any entity succeeding to the
corporate trust business of the Trustee, shall be the successor of the Trustee
or such Fiscal Agent, as the case may be, hereunder, provided such entity shall
be eligible under the provisions of Section 8.06 or Section 8.17, as applicable,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto, anything herein to the contrary notwithstanding.

          SECTION 8.10.  Appointment of Co-Trustee or Separate Trustee.

          (a) Notwithstanding any other provisions hereof, at any time, for the
purpose of meeting any legal requirements of any jurisdiction in which any part
of the Trust Fund or property securing the same may at the time be located, the
Trustee shall have the power and shall execute and deliver all instruments to
appoint one or more Persons approved by the Trustee to act as co-trustee or
co-trustees, jointly with the Trustee, or separate trustee or separate trustees,
of all or any part of the Trust Fund, and to vest in such Person or Persons, in
such capacity, such title to the Trust Fund, or any part thereof, and, subject
to the other provisions of this Section 8.10, such powers, duties, obligations,
rights and trusts as the Master Servicer and the Trustee may consider necessary
or desirable. No co-trustee or separate trustee hereunder shall be required to
meet the terms of eligibility as a successor trustee under Section 8.06
hereunder and no notice to Holders of Certificates of the appointment of
co-trustee(s) or separate trustee(s) shall be required under Section 8.08
hereof.

          (b) In the case of any appointment of a co-trustee or separate trustee
pursuant to this Section 8.10, all rights, powers, duties and obligations
conferred or imposed upon the Trustee shall be conferred or imposed upon and
exercised or performed by the Trustee and such separate trustee or co-trustee
jointly, except to the extent that under any law of any jurisdiction in which
any particular act or acts are to be performed (whether as Trustee hereunder or
as successor to the Master Servicer or the Special Servicer hereunder), the
Trustee shall be incompetent or unqualified to perform such act or acts, in
which event such rights, powers, duties and obligations (including the holding
of title to the Trust Fund or any portion thereof in any such jurisdiction)
shall be exercised and performed by such separate trustee or co-trustee at the
direction of the Trustee.

          (c) Any notice, request or other writing given to the Trustee shall be
deemed to have been given to each of the then separate trustees and co-trustees,
as effectively as if given to each of them. Every instrument appointing any
separate trustee or co-trustee shall refer to this Agreement and the conditions
of this Article VIII. Each separate trustee and co-trustee, upon its acceptance
of the trusts conferred, shall be vested with the estates or property specified
in its instrument of appointment, either jointly with the Trustee or separately,
as may be provided therein, subject to all the provisions of this Agreement,
specifically including every provision of this Agreement relating to the conduct
of, affecting the liability of, or affording protection to, the Trustee. Every
such instrument shall be filed with the Trustee.


                                     -345-



          (d) Any separate trustee or co-trustee may, at any time, constitute
the Trustee, its agent or attorney-in-fact, with full power and authority, to
the extent not prohibited by law, to do any lawful act under or in respect of
this Agreement on its behalf and in its name. If any separate trustee or
co-trustee shall cease to exist, become incapable of acting, resign or be
removed, all of its estates, properties, rights, remedies and trusts vested
therein pursuant to the applicable instrument of appointment and this Section
8.10, shall vest in and be exercised by the Trustee, to the extent permitted by
law, without the appointment of a new or successor trustee.

          (e) The appointment of a co-trustee or separate trustee under this
Section 8.10 shall not relieve the Trustee of its duties and responsibilities
hereunder.

          SECTION 8.11.  Appointment of Custodians.

          The Trustee may appoint at the Trustee's expense one or more
Custodians to hold all or a portion of the Mortgage Files as agent for the
Trustee. Each Custodian shall be a depository institution supervised and
regulated by a federal or state banking authority, shall have combined capital
and surplus of at least $10,000,000, shall be qualified to do business in the
jurisdiction in which it holds any Mortgage File and shall not be the Depositor,
any Mortgage Loan Seller or any Affiliate of any of them. Neither the Master
Servicer nor the Special Servicer shall have any duty to verify that any such
Custodian is qualified to act as such in accordance with the preceding sentence.
The Trustee may enter into an agreement to appoint a Custodian which is not the
Trustee, provided that such agreement: (i) is consistent with this Agreement in
all material respects and requires the Custodian to comply with all of the
applicable conditions of this Agreement; (ii) provides that if the Trustee shall
for any reason no longer act in the capacity of Trustee hereunder, the successor
trustee or its designee may thereupon assume all of the rights and, except to
the extent they arose prior to the date of assumption, obligations of the
Custodian under such agreement or, alternatively, may terminate such agreement
without cause and without payment of any penalty or termination fee; and (iii)
may provide that the related Custodian will be entitled to be indemnified out of
the assets of the Trust Fund in connection with losses arising from the
performance by such Custodian of its duties in accordance with the provisions of
the related custodial agreement if and to the extent such indemnification would
be permitted under Section 8.05(b) with respect to agents of the Trustee. The
appointment of one or more Custodians shall not relieve the Trustee from any of
its obligations hereunder, and the Trustee shall remain responsible for all acts
and omissions of any Custodian. In the absence of any other Person appointed in
accordance herewith acting as Custodian, the Trustee agrees to act in such
capacity in accordance with the terms hereof. Notwithstanding anything herein to
the contrary, if the Trustee is no longer the Custodian, any provision or
requirement herein requiring notice or any information or documentation to be
provided to the Custodian shall be construed to require that such notice,
information or documents also be provided to the Trustee. Any Custodian
hereunder shall at all times maintain a fidelity bond and errors and omissions
policy in amounts customary for custodians performing duties similar to those
set forth in this Agreement and, in any event, satisfying the same requirements
(including as to the insurer) as are applicable to any such bond or policy
required to be maintained by the Master Servicer pursuant to Section 3.07. Any
engagement of a third party to act as Custodian with respect to the Mortgage
File or any portion thereof with respect to a Serviced Loan Combination shall be
subject to any relevant provisions of the related Co-Lender Agreement.

          SECTION 8.12.  Appointment of Authenticating Agents.

          (a) The Trustee may appoint at the Trustee's expense an Authenticating
Agent, which shall be authorized to act on behalf of the Trustee in
authenticating Certificates. The Trustee shall cause any such Authenticating
Agent to execute and deliver to the Trustee an instrument in which such
Authenticating Agent shall agree to act in such capacity, with the obligations
and responsibilities herein. Each Authenticating Agent must be organized and
doing business under the laws of the United States of America or of any State,
authorized under such laws to carry on a trust business, have a combined capital
and surplus of at least $15,000,000, and be subject to supervision or
examination by federal or state authorities. Each Authenticating Agent shall be
subject to the same obligations, standard of care, protection and indemnities as
would be imposed on, or would protect, the Trustee hereunder. The appointment of
an Authenticating Agent shall not relieve the Trustee from any of its
obligations hereunder, and the Trustee shall remain responsible and liable for
all acts and omissions of the Authenticating Agent. In the absence of any other
Person appointed in accordance herewith acting as Authenticating Agent, the
Trustee hereby agrees to act in such capacity in accordance with the terms
hereof. Notwithstanding anything herein to the contrary, if the Trustee is no
longer the Authenticating Agent, any provision or requirement herein requiring
notice or any information or documentation to be provided to the Authenticating
Agent shall be construed to require that such notice, information or
documentation also be provided to the Trustee.

          (b) Any Person into which any Authenticating Agent may be merged or
converted or with which it may be consolidated, or any Person resulting from any
merger, conversion, or consolidation to which any Authenticating Agent shall be
a party, or any Person succeeding to the corporate agency business of any
Authenticating Agent, shall continue to be the Authenticating Agent without the
execution or filing of any paper or any further act on the part of the Trustee
or the Authenticating Agent.

          (c) Any Authenticating Agent appointed in accordance with this Section
8.12 may at any time resign by giving at least 30 days' advance written notice
of resignation to the Trustee, the Certificate Registrar, the Master Servicer,
the Special Servicer and the Depositor. The Trustee may at any time terminate
the agency of any Authenticating Agent appointed in accordance with this Section
8.12 by giving written notice of termination to such Authenticating Agent, the
Master Servicer, the Certificate Registrar and the Depositor. Upon receiving a
notice of such a resignation or upon such a termination, or in case at any time
any Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section 8.12, the Trustee may appoint a successor
Authenticating Agent, in which case the Trustee shall give written notice of
such appointment to the Master Servicer, the Certificate Registrar and the
Depositor and shall mail notice of such appointment to all Holders of
Certificates; provided, however, that no successor Authenticating Agent shall be
appointed unless eligible under the provisions of this Section 8.12. Any
successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the rights, powers, duties and responsibilities of
its predecessor hereunder, with like effect as if originally named as
Authenticating Agent.

          SECTION 8.13.  Appointment of Tax Administrators.

          (a) The Trustee may appoint at the Trustee's expense any Person with
appropriate tax-related experience to act as Tax Administrator hereunder;
provided that, in the absence of any other Person appointed in accordance
herewith acting as Tax Administrator, the Trustee agrees to act in such


                                     -347-



capacity in accordance with the terms hereof. The appointment of a Tax
Administrator shall not relieve the Trustee from any of its obligations
hereunder, and the Trustee shall remain responsible for all acts and omissions
of the Tax Administrator. The Trustee shall cause any such Tax Administrator
appointed by it to execute and deliver to the Trustee an instrument in which
such Tax Administrator shall agree to act in such capacity, with the obligations
and responsibilities herein.

          (b) Any Person into which any Tax Administrator may be merged or
converted or with which it may be consolidated, or any Person resulting from any
merger, conversion, or consolidation to which any Tax Administrator shall be a
party, or any Person succeeding to the corporate agency business of any Tax
Administrator, shall continue to be the Tax Administrator without the execution
or filing of any paper or any further act on the part of the Trustee or the Tax
Administrator.

          (c) Any Tax Administrator appointed in accordance with this Section
8.13 may at any time resign by giving at least 30 days' advance written notice
of resignation to the Trustee, the Certificate Registrar, the Master Servicer,
the Special Servicer and the Depositor. The Trustee may at any time terminate
the agency of any Tax Administrator appointed in accordance with this Section
8.13 by giving written notice of termination to such Tax Administrator, the
Master Servicer, the Certificate Registrar and the Depositor. Upon receiving a
notice of such a resignation or upon such a termination, or in case at any time
any Tax Administrator shall cease to be eligible in accordance with the
provisions of this Section 8.13, the Trustee may appoint a successor Tax
Administrator, in which case the Trustee shall give written notice of such
appointment to the Master Servicer, the Special Servicer and the Depositor and
shall mail notice of such appointment to all Holders of Certificates; provided,
however, that no successor Tax Administrator shall be appointed unless eligible
under the provisions of this Section 8.13. Any successor Tax Administrator upon
acceptance of its appointment hereunder shall become vested with all the rights,
powers, duties and responsibilities of its predecessor hereunder, with like
effect as if originally named as Tax Administrator.

          SECTION 8.14.  Access to Certain Information.

          (a) The Trustee shall afford to the Master Servicer, the Special
Servicer and the Depositor, and to the OTS, the FDIC and any other banking or
insurance regulatory authority that may exercise authority over any
Certificateholder, Certificate Owner or Serviced Pari Passu Non-Trust Mortgage
Loan Noteholder, access to any documentation regarding the Trust Mortgage Loans
(or, in the case of a Serviced Pari Passu Non-Trust Mortgage Loan Noteholder,
the Serviced Pari Passu Non-Trust Mortgage Loan) within its control that may be
required to be provided by this Agreement or by applicable law. Such access
shall be afforded without charge but only upon reasonable prior written request
and during normal business hours at the offices of the Trustee designated by it.

          (b) The Trustee shall maintain in its possession and, upon reasonable
prior written request and during normal business hours, shall make available at

(viii) the most recent appraisal for each Mortgaged Property and REO Property
that has been delivered to the Trustee (each appraisal obtained hereunder with
respect to any Mortgaged Property or REO Property to be delivered to the Trustee

its having been obtained); (ix) any and all Officer's Certificates and other

Mortgaged Property and/or the borrower under such Outside Serviced Trust

from a related Outside Servicer or other applicable party under the related
Outside Servicing Agreement and delivered to the Trustee since the Closing Date.
The Trustee shall provide copies of any and all of the foregoing items upon
written request of any of the parties set forth in the previous sentence;
however, except in the case of the Rating Agencies, the Trustee shall be
permitted to require payment of a sum sufficient to cover the reasonable costs
and expenses of providing such copies. Upon the reasonable request of any
Certificateholder, or any Certificate Owner identified to the Trustee to the
Trustee's reasonable satisfaction, the Trustee shall request from the Master
Servicer copies (at the expense of such Certificateholder or Certificate Owner
if the Master Servicer or Special Servicer charges a fee to cover the reasonable
cost of making such copies available) of any inspection reports prepared by the
Master Servicer or the Special Servicer, copies of any operating statements,
rent rolls and financial statements obtained by the Master Servicer or the

of Certificateholders and Certificate Owners, a written confirmation executed by
the requesting Person substantially in the form of Exhibit L-1 (or in such other

ownership interest or prospective ownership


                                     -349-

investment in Certificates and will otherwise keep such information
confidential.

          (c) The Trustee shall not be liable for providing or disseminating
information in accordance with Section 8.14(a) or (b).

          (a) With respect to any Exchange Act Reporting Year, the Trustee
shall:

               (i) as soon as reasonably practicable (but in any event within 15
     days or such shorter period as may be provided under the Exchange Act and
     the rules and regulations promulgated thereunder) after each Distribution

     Reportable Event and otherwise, to the extent delivered by written notice
     to, or otherwise actually known by a Responsible Officer of, the Trustee,
     any other Form 10-D Required Information to be reported for the period
     covered by the subject Form 10-D;

               (ii) during such Exchange Act Reporting Year, at the direction of
     the Depositor, in accordance with the Exchange Act, the rules and
     regulations promulgated thereunder, and applicable releases and "no-action
     letters" issued by the Commission, prepare for filing, arrange for
     execution by the Depositor and properly and timely file with the Commission
     with respect to the Trust, a Current Report on Form 8-K regarding and

     provided with written notice of, such information), within the time periods
     specified under Form 8-K, the Exchange Act, the rules and regulations
     promulgated thereunder and applicable releases and "no-action letters"
     issued by the Commission; provided that the Depositor shall cooperate with
     the Trustee to determine the applicable required time period; and provided,
     further, that, if the Depositor directs the Trustee to file a Current
     Report on Form 8-K in accordance with this clause (ii), the Depositor shall

     shall further include a Sarbanes-Oxley Certification and shall include any

     Trustee);

               (iv) at the reasonable request of, and in accordance with the
     reasonable directions of, the Certifying Party (as defined in Section
     8.15(d)) or the Depositor, prepare for filing, arrange for execution by the
     Depositor and promptly file with the Commission an amendment to any Current

provided that (x) the Trustee shall not have any responsibility to file any
items (other than those generated by it) that have not been received in a format
suitable (or readily convertible into a format suitable) for electronic filing
via the EDGAR system and shall not have any responsibility to convert any such
items to such format (other than those items generated by it or that are readily
convertible to such format) and (y) the Depositor shall be responsible for
preparing, executing and filing (via the EDGAR system) a Current Report on Form
8-K reporting the establishment of the Trust and a Current Report on Form 8-K
whereby this Agreement will be filed as an exhibit (the Current Reports on Form

Current Reports on Form 8-K"); and provided, further, that if all or any
required portion of an Annual Report on Form 10-K or a Distribution Report on
Form 10-D cannot be timely filed by the Trustee (other than for a reason
contemplated by Rule 12b-25(g) of the Exchange Act), then (i) the Trustee (upon
becoming aware thereof or the reasonable likelihood thereof) shall immediately
notify the Depositor, (ii) the Trustee shall (to the extent appropriate and to
the extent directed by the Depositor) file a Form 12b-25 (17 C.F.R. 249.322) in
connection therewith consistent with Rule 12b-25 of the Exchange Act, each party
hereto shall reasonably cooperate with the Trustee and the Depositor to complete
the subject Exchange Act Report and such Exchange Act Report (or the applicable
portions thereof) shall be filed with the Commission as soon as reasonably
practicable and, if the Depositor is relying upon Rule 12b-25 of the Exchange

                                     -351-



          All Current Reports on Form 8-K, Distribution Reports on Form 10-D and
Annual Reports on Form 10-K, as well as any amendments to those reports, that
are to be filed with respect to the Trust pursuant to the Exchange Act, and the
rules and regulations promulgated thereunder, and this Section 8.15(a), are
(together with the exhibits thereto) herein referred to as the "Exchange Act
Reports". The Exchange Act Reports, exclusive of the Initial Current Reports on
Form 8-K, are herein referred to as the "Subsequent Exchange Act Reports." All
Subsequent Exchange Act Reports prepared by the Trustee pursuant to this Section
8.15(a) shall be executed by the Depositor promptly upon delivery thereto,
subject to the Subsequent Exchange Act Report being in form and substance
reasonably acceptable thereto. The senior officer in charge of securitization
for the Depositor shall sign the Sarbanes-Oxley Certification included in each
Form 10-K Report with respect to the Trust.

          Notwithstanding any other provision of this Agreement, the Trustee
shall have no liability to any Person with respect to any failure to properly
prepare or timely file any of the Subsequent Exchange Act Reports to the extent
that such failure is not the result of any negligence, bad faith or willful
misconduct on its part. The Trustee shall have no liability to any Person for a
failure to file on a timely basis any Subsequent Exchange Act Report to the
extent that the Trustee is not provided by any unaffiliated third party within
the time frames set forth in this Agreement all required attachments and
information (including notices with respect thereto) to be filed with such
Subsequent Exchange Act Report in properly executed form. The Trustee shall be
entitled to conclusively rely upon, without any duty to review or analyze, the
form and content of any information, disclosure, attachments or exhibits
provided to it for inclusion in any Subsequent Exchange Act Report. The parties
to this Agreement acknowledge that the performance by the Trustee of its duties
under this Section 8.15 related to the timely preparation, arrangement for
execution and filing of Subsequent Exchange Act Reports is dependent upon other
parties to this Agreement observing all applicable deadlines in the performance
of their duties under Sections 3.13, 3.14 and 8.15. Other than to the extent the
Trustee is required to provide notice of any failure to deliver in accordance
with this Agreement, the Trustee has no duty under this Section 8.15 or
otherwise under this Agreement to enforce the performance by the other parties
to this Agreement of their duties under this Section 8.15.

          The Trustee shall make available to all Certificateholders and
Certificate Owners on its internet website each Subsequent Exchange Act Report
that is filed with the Commission with respect to the Trust. The Trustee shall
post each such report on its internet website as soon as reasonably practicable
after the filing thereof with the Commission. In addition, the Trustee shall,
free of charge, upon request, deliver to any Certificateholder, Certificate
Owner or party identified as a prospective Certificateholder or Certificate
Owner copies of all Subsequent Exchange Act Reports that are filed with the
Commission with respect to the Trust. Any request contemplated by the prior
sentence shall be made to LaSalle Bank, N.A., 135 South LaSalle Street, Suite
1625, Chicago, Illinois 60603, Attention: Kristen Packwood (telephone number:
(312) 904-4207), or to such other Person, address and/or phone number as the
Trustee may specify by notice to Certificateholders.

          (b) At all times during each Exchange Act Reporting Year, each of the
Trustee, the Master Servicer and the Special Servicer shall (and shall use
reasonable efforts to cause each Servicing Representative that is a Servicer
acting on its behalf hereunder and, solely in the case of the Trustee, each
Trustee Appointee to) monitor for, and (in accordance with the timeframes set
forth in this Section 8.15(b)) notify (including with such notice the Exchange
Act Reportable Event Notification attached hereto as Exhibit U) the Depositor
and the Trustee in writing of, the occurrence or existence of any and all
events, conditions, circumstances and/or matters that constitute or may
constitute related Exchange


                                     -352-



Act Reportable Events with respect thereto; provided that, unless any such
particular event, condition, circumstance and/or matter specifically relates to
the party obligated to undertake such monitoring, any Affiliate thereof, any
Servicing Representative that is a Servicer retained or engaged thereby or,
solely in the case of the Trustee, any Trustee Appointee, the obligation to so
monitor for any such particular event, condition, circumstance and/or matter
shall be limited to maintaining a reasonable awareness as regards the existence
thereof in the normal course of performing its respective obligations and duties
hereunder or otherwise in respect of the Trust Fund. Each of the Trustee, Master
Servicer and Special Servicer shall provide such notice of any Exchange Act
Reportable Event to the Trustee and the Depositor (i) no later than 5 calendar
days after the Distribution Date with respect to any Exchange Act Reportable
Event to be disclosed on Form 10-D, (ii) no later than March 15 in any year in
which the Trustee will file a Form 10-K for the Trust with respect to any
Exchange Act Reportable Event to be disclosed on Form 10-K, and (iii) no later
than Noon (New York City time) on the 2nd Business Day after the occurrence of
any Exchange Act Reportable Event to be disclosed on Form 8-K; provided, that,
unless (x) the applicable Exchange Act Reportable Event relates to such party or
(y) such party has failed to monitor for any such particular event, condition,
circumstance and/or matter in accordance with the preceding sentence, then the
Trustee, the Master Servicer and the Special Servicer shall be obligated to
provide notice of any Exchange Act Reportable Event as set forth in clauses (i),
(ii) and (iii) above only to the extent a Servicing Officer or Responsible
Officer, as applicable, thereof has actual knowledge or has received notice of
such Exchange Act Reportable Event. Upon becoming aware of any Form 8-K Required
Information, the Trustee shall promptly notify the Depositor in writing that the
filing of a Current Report on Form 8-K may be required with respect to any of
the events, conditions, circumstances and/or matters that constitute such Form
8-K Required Information and, further, shall consult with the Depositor
regarding whether to prepare and file a Current Report on Form 8-K under Section
8.15(a)(ii) above with respect to such events, conditions, circumstances and/or
matters and, if prepared, the form and content of such filing (and the Trustee
shall be entitled to rely on a written direction of the Depositor with regard to
whether to make and the form and content of such filing). For purposes of this
paragraph, provided that (x) the subject party has monitored for the particular
event, condition, circumstance and/or matter in accordance with the third
preceding sentence and (y) the applicable Exchange Act Reportable Event does not
relate to such party, none of the Trustee, the Master Servicer or the Special
Servicer shall be considered to be aware of any related Exchange Act Reportable
Event, and the Trustee shall not be considered to be aware of any Form 8-K
Required Information, Form 10-D Required Information or Form 10-K Required
Information, unless a Responsible Officer (in the case of the Trustee) or a
Servicing Officer (in the case of the Master Servicer or the Special Servicer)
thereof has actual knowledge.

          Upon reasonable request of the Depositor or the Trustee, each other
party hereto (including the Trustee, if the Depositor is the requesting party,
and the Depositor, if the Trustee is the requesting party) shall (and shall use
reasonable efforts to cause any Servicing Representative that is a Servicer
acting on its behalf hereunder or, solely in the case of the Trustee, any
Trustee Appointee, to) promptly provide to the requesting party any information
in its possession as is necessary or appropriate for the Depositor or the
Trustee, as applicable, to prepare fully and properly any Exchange Act Report
with respect to the Trust in accordance with the Securities Act, the Exchange
Act and the rules and regulations promulgated thereunder.

          If, during any Exchange Act Reporting Year, a new Master Servicer,
Special Servicer or Trustee is appointed, then such new Master Servicer, Special
Servicer or Trustee, as the case may be, shall in connection with its acceptance
of such appointment provide the Depositor and, in the case of a


                                     -353-



new Master Servicer or Special Servicer, the Trustee with such information
regarding itself, its business and operations and its experience and practices
regarding the duties it is to perform under this Agreement, as is required to be
reported by the Depositor pursuant to Item 6.02 of Form 8-K. If, during any
Exchange Act Reporting Year, the Master Servicer, Special Servicer or Trustee
appoints a Servicing Representative that constitutes a Servicer contemplated by
Item 1108(a)(2) of Regulation AB, then the Master Servicer, Special Servicer or
Trustee, as the case may be, shall cause such Servicing Representative, in
connection with its acceptance of such appointment, to provide the Depositor and
the Trustee with such information regarding itself, its business and operations
and its servicing experience and practices, as is required to be reported by the
Depositor pursuant to Item 6.02 of Form 8-K.

          Each of the Trustee, any Fiscal Agent, the Master Servicer and the
Special Servicer acknowledges and agrees that the information to be provided by
it (or by any Servicing Representative acting on its behalf hereunder or, solely
in the case of the Trustee, any Trustee Appointee) pursuant to or as
contemplated by this Section 8.15(b) is intended to be used in connection with
the preparation of Exchange Act Reports with respect to the Trust.

          Upon notice that any Serviced Non-Trust Mortgage Loan has been
included in a Non-Trust Mortgage Loan Securitization Trust, then the Form 8-K
Required Information, Form 10-D Required Information and Form 10-K Required
Information required to be reported to the Depositor under this Section 8.15(b)
shall simultaneously be reported to the depositor and trustee in respect of such
Non-Trust Mortgage Loan Securitization Trust to the extent required for such
depositor and/or trustee to satisfy any Exchange Act reporting requirements in
respect of such Non-Trust Mortgage Loan Securitization Trust.

          (c) If as of the beginning of any fiscal year for the Trust (other

less than 300 holders (which may consist of (x) in the case of Registered
Certificates held in definitive form, direct Holders of such Definitive
Certificates, and/or (y) in the case of Registered Certificates held in
book-entry form through the Depository, Depository Participants having accounts
with the Depository), the Trustee shall, in accordance with the Exchange Act and
the rules and regulations promulgated thereunder, timely file a Form 15 with
respect to the Trust suspending all reporting requirements under the Exchange
Act and shall post such Form 15 to its internet website.

          (d) As and to the extent required by the Sarbanes-Oxley Act of 2002
(the "Sarbanes-Oxley Act") and the rules adopted by the Commission with respect
thereto, all Annual Reports on Form 10-K filed with the Commission shall include
such certification as complies in form and substance with the Sarbanes-Oxley Act
and the rules and regulations promulgated thereunder (such certification, the
"Sarbanes-Oxley Certification"; any party hereto whose officer is to sign, in
accordance with the Sarbanes-Oxley Act and the rules and regulations promulgated
thereunder, any Sarbanes-Oxley Certification with respect to the Trust, a
"Certifying Party"; and any officer who is to sign, in accordance with the
Sarbanes-Oxley Act and the rules and regulations promulgated thereunder, any
Sarbanes-Oxley Certification, a "Certifying Officer").

          (e) The Depositor shall be the Certifying Party with respect to a
Sarbanes-Oxley Certification filed as part of each Annual Report on Form 10-K
relating to the Trust. In connection with the filing of any Annual Report on
Form 10-K with respect to the Trust as contemplated by Section 8.15(a), the
Certifying Party shall, no later than March 25 of the applicable calendar year
in which the


                                     -354-

Trustee, with respect to the Trust, for filing with such Annual Report on Form
10-K, the Sarbanes-Oxley Certification that is to be included as part of such
Annual Report on Form 10-K.

          (f) No later than (i) 12:00 noon, New York City time, on the Business

Current Report on Form 8-K) that is to be made with respect to the Trust as

Exchange Act Report that is to be made with respect to the Trust as contemplated
by Section 8.15(a), the Trustee shall deliver a copy of such Exchange Act
Report, together with all exhibits thereto (to the extent received by the
Trustee), for review by the Depositor and the Special Servicer. Promptly upon
receipt of any such report and the accompanying exhibits, each of the Depositor
and the Special Servicer shall (and, if and to the extent applicable, shall
cause any Servicing Representative acting on its behalf hereunder to) promptly
review such report and the accompanying exhibits and notify the Trustee of any
material misstatements or omissions relating thereto that come to its attention,
which material misstatements or omissions the Trustee shall correct (with
written evidence of such correction to be sent to the Depositor and the Special
Servicer) prior to the filing of such report and the accompanying exhibits.

          (g) No later than March 20 of any year in which an Annual Report on
Form 10-K is to be filed with respect to the Trust, the Trustee shall cause a
Responsible Officer of the Trustee to execute and deliver to each Certifying
Party and Certifying Officer a certification (a "Trustee Backup Certification"),
which Trustee Backup Certification shall be in the form of Exhibit P attached
hereto. The Trustee shall indemnify and hold harmless each Certifying Party and
Certifying Officer to whom it delivers any Trustee Backup Certification for all
losses, liabilities, claims, damages, costs and expenses (including reasonable
attorneys' fees and expenses) resulting from a breach of any certification made
in such Trustee Backup Certification, as well as any other losses, liabilities,
claims, damages, costs and expenses (including reasonable attorneys' fees and
expenses) incurred by such Certifying Party or Certifying Officer, as the case
may be, in connection with the execution and delivery of the subject
Sarbanes-Oxley Certification resulting from the negligence, bad faith or willful
misfeasance of the Trustee in connection with the performance by the Trustee of
its duties hereunder.

          (h) No later than March 20 of the year in which an Annual Report on
Form 10-K is to be filed with respect to the Trust, unless the Master Servicer
is to be the Certifying Party, the Master Servicer shall cause an authorized

of Exhibit Q attached hereto and shall cover all of the Trust Mortgage Loans and
REO Properties (including any Outside Serviced Trust Mortgage Loans and any
Outside Administered REO Properties, to the extent required in accordance with
Exhibit Q). In addition, within the time periods set forth in the related
Co-Lender Agreement (or, if no such time periods are set forth therein, by March
20 of any calendar year in which any Annual Report on Form 10-K is to be filed
with respect to the related securitization trust), the Master Servicer shall
execute and deliver to the depositor, trustee and/or other certifying party and

                                     -355-



unpaid principal balance in excess of $20,000,000, a master servicer backup
certification covering such Serviced Non-Trust Mortgage Loan (and that may be
relied on by each such party to which it is delivered), which master servicer
backup certification will be substantially similar to the Master Servicer Backup
Certification and will cover only the subject Non-Trust Mortgage Loan. The
Master Servicer shall indemnify and hold harmless each Certifying Party and
Certifying Officer to whom it delivers any Master Servicer Backup Certification
for all losses, liabilities, claims, damages, costs and expenses (including
reasonable attorneys' fees and expenses) resulting from a breach of any
certification made in such Master Servicer Backup Certification, as well as any
other losses, liabilities, claims, damages, costs and expenses (including
reasonable attorneys' fees and expenses) incurred by such Certifying Party or
Certifying Officer, as the case may be, in connection with the execution and
delivery of the subject Sarbanes-Oxley Certification, in each case, resulting

connection with the performance by the Master Servicer of its duties hereunder.

          (i) No later than March 20 of the year in which any Annual Report on
Form 10-K is to be filed with respect to the Trust, the Special Servicer shall

each Certifying Party and Certifying Officer a certification (a "Special
Servicer Backup Certification"), which Special Servicer Backup Certification
shall be in the form of Exhibit R attached hereto and shall cover all of the
Specially Serviced Trust Mortgage Loans and Administered REO Properties
(together with any Outside Serviced Trust Mortgage Loan that is then specially
serviced under the related Outside Servicing Agreement or any Outside
Administered REO Property, if the Special Servicer is, is an Affiliate of, or
receives a comparable certification relating thereto from, the related Outside
Special Servicer). In addition, within the time periods set forth in the related
Co-Lender Agreement (or, if no such time periods are set forth therein, by March
20 of any calendar year in which any Annual Report on Form 10-K is to be filed
with respect to the related securitization trust), the Special Servicer shall
execute and deliver to the depositor, trustee and/or other certifying party and
certifying officer executing a Sarbanes-Oxley Certification in connection with
any public securitization of any Serviced Non-Trust Mortgage Loan that is either
a Pari Passu Non-Trust Mortgage Loan or has, as of the Closing Date an unpaid
principal balance in excess of $20,000,000, a special servicer backup
certification covering such Serviced Non-Trust Mortgage Loan (and that may be
relied on by each such party to which it is delivered), which special servicer
backup certification will be substantially similar to the Special Servicer
Backup Certification and will cover only the subject Non-Trust Mortgage Loan.
The Special Servicer shall indemnify and hold harmless each Certifying Party and
Certifying Officer to whom it delivers any Special Servicer Backup Certification
for all losses, liabilities, claims, damages, costs and expenses (including
reasonable attorneys' fees and expenses) resulting from a breach of any
certification made in such Special Servicer Backup Certification, as well as any

connection with the performance by the Special Servicer of its duties hereunder.

          (j) The respective parties hereto agree to cooperate with all
reasonable requests made by any Certifying Party or Certifying Officer in
connection with such Person's attempt to conduct any due diligence that such
Person reasonably believes to be appropriate in order to allow it to deliver any
Sarbanes-Oxley Certification or portion thereof with respect to the Trust.


                                     -356-

Servicer or the Trustee with respect to all or any portion of the Trust Fund
fails to deliver, if and to the extent applicable in accordance with Regulation
AB and this Agreement, any of the items set forth in the following clauses (i),
(ii) and/or (iii), then the Master Servicer, the Special Servicer or the

Servicing Representative relating to the Subject Securitization Transaction: (i)
any Annual Statement of Compliance contemplated by Item 1123 of Regulation AB,

any Servicing Representative retained or engaged thereby has defaulted on its
obligation to deliver, (i) if and to the extent applicable in accordance with
Regulation AB and this Agreement, any of the items set forth in clauses (i),

subject Servicing Representative relating to the Subject Securitization
Transaction; provided that this provision shall not apply to the initial Master
Servicer and the subject matter of this sentence, insofar as it relates to the
initial Master Servicer, shall be covered by the Master Servicer Indemnification
Agreement.

          (m) Each of the Master Servicer, the Special Servicer and the Trustee

Depositor, LBHI and Lehman Brothers harmless from and against, any and all
losses, liabilities, claims, damages, costs and expenses whatsoever, as

Special Servicer or the Trustee, as the case may be, or any Servicing
Representative thereof (exclusive of a Sub-Servicer identified on Exhibit K
hereto, insofar as such Sub-Servicer does not service any Mortgage Loans other
than those identified by the Depositor on the Closing Date), to deliver or cause
to be delivered to the Trustee, the Depositor and each affected Serviced
Non-Trust Mortgage Loan Noteholder (which shall relate to a Serviced Non-Trust
Mortgage Loan for which deliveries are required under


                                     -357-



Section 3.29 hereof), with respect to any Exchange Act Reporting Year, as and
when required or contemplated by Section 3.13 and/or Section 3.14: (i) any

any Annual Attestation Report (together with, if required to be filed with the
Commission under applicable law, the accountants' consent authorizing the filing

clarify or amend any provision of this Section 8.15, this Agreement shall be
amended to reflect the new agreement between the parties covering matters in
this Section 8.15 pursuant to Section 11.01, which amendment shall not require
any Opinion of Counsel or Rating Agency confirmations or the consent of any
Certificateholder or any Serviced Non-Trust Mortgage Loan Noteholder; provided
that no such amendment shall diminish the filing requirements under this Section
8.15 on the part of the parties to this Agreement, as a collective whole, in
contravention of applicable law.

          (o) With respect to any notice required to be delivered by the Trustee

          (p) If any party hereunder is also acting as an Outside Servicer with
respect to an Outside Serviced Trust Mortgage Loan or Outside Administered REO

          (r) The Master Servicer, with respect to Performing Serviced Mortgaged

provided, that notwithstanding anything to the contrary in Section 8.15(q) or
(r), the Master Servicer shall not be required to deliver any of the items set
forth in Section 8.15(q) or (r) subsequent to the filing of the final Form 10-K

          SECTION 8.16.  Representations and Warranties of Trustee.

          (a) The Trustee hereby represents and warrants to the Master Servicer,
the Special Servicer and the Depositor and for the benefit of the
Certificateholders and the Serviced Non-Trust Mortgage Loan Noteholders, as of
the Closing Date, that:

               (i) The Trustee is a national banking association duly organized,
     validly existing and in good standing under the laws of the United States
     of America.

               (ii) The execution and delivery of this Agreement by the Trustee,
     and the performance and compliance with the terms of this Agreement by the
     Trustee, will not violate the Trustee's organizational documents or
     constitute a default (or an event which, with notice or lapse of time, or
     both, would constitute a default) under, or result in the breach of, any
     material agreement or other instrument to which it is a party or which is
     applicable to it or any of its assets.

               (iii) Except to the extent that the laws of certain jurisdictions
     in which any part of the Trust Fund may be located require that a
     co-trustee or separate trustee be appointed to act with respect to such
     property as contemplated by Section 8.10, the Trustee has the full power
     and authority to enter into and consummate all transactions contemplated by
     this Agreement, has duly authorized the execution, delivery and performance
     of this Agreement, and has duly executed and delivered this Agreement.

               (iv) This Agreement, assuming due authorization, execution and
     delivery by the other parties hereto, constitutes a valid, legal and
     binding obligation of the Trustee, enforceable against the Trustee in
     accordance with the terms hereof, subject to (A) applicable bankruptcy,
     insolvency, reorganization, moratorium and other laws affecting the
     enforcement of creditors' rights generally, and (B) general principles of
     equity, regardless of whether such enforcement is considered in a
     proceeding in equity or at law.

               (v) The Trustee is not in violation of, and its execution and
     delivery of this Agreement and its performance and compliance with the
     terms of this Agreement, including, but not limited to, its responsibility
     to make P&I Advances if the Master Servicer fails to make a P&I Advance,
     will not constitute a violation of, any law, any order or decree of any
     court or arbiter, or any order, regulation or demand of any federal, state
     or local governmental or regulatory authority, which violation, in the
     Trustee's good faith and reasonable judgment, is likely to affect
     materially and adversely either the ability of the Trustee to perform its
     obligations under this Agreement or the financial condition of the Trustee.


                                     -359-



               (vi) No litigation is pending or, to the best of the Trustee's
     knowledge, threatened against the Trustee that, if determined adversely to
     the Trustee, would prohibit the Trustee from entering into this Agreement
     or, in the Trustee's good faith and reasonable judgment, is likely to
     materially and adversely affect either the ability of the Trustee to
     perform its obligations under this Agreement or the financial condition of
     the Trustee.

               (vii) Any consent, approval, authorization or order of any court
     or governmental agency or body required for the execution, delivery and
     performance by the Trustee of or compliance by the Trustee with this
     Agreement, or the consummation of the transactions contemplated by this
     Agreement, has been obtained and is effective, except where the lack of
     consent, approval, authorization or order would not have a material adverse
     effect on the performance by the Trustee under this Agreement.

               (viii) The Trustee is eligible to act as trustee hereunder in
     accordance with Section 8.06.

               (ix) The Trustee is, with respect to each Combination Trust
     Mortgage Loan, an entity permitted under the related Co-Lender Agreement to
     be a transferee and holder of such Trust Mortgage Loan.

          (b) The representations and warranties of the Trustee set forth in
Section 8.16(a) shall survive the execution and delivery of this Agreement and
shall inure to the benefit of the Persons for whose benefit they were made for
so long as the Trust Fund remains in existence. Upon discovery by any party
hereto of any breach of any of the foregoing representations, warranties and
covenants, the party discovering such breach shall give prompt written notice
thereof to the other parties hereto.

          (c) Any successor Trustee shall be deemed to have made, as of the date
of its succession, each of the representations and warranties set forth in
Section 8.16(a), subject to such appropriate modifications to the representation
and warranty set forth in Section 8.16(a)(i) to accurately reflect such
successor's jurisdiction of organization and whether it is a corporation,
partnership, bank, association or other type of organization.

          SECTION 8.17.  Appointment of a Fiscal Agent.

          (a) In order to satisfy the eligibility requirements of Section 8.06
(insofar as such requirements relate to ratings), the Trustee may appoint a
Fiscal Agent. Any Fiscal Agent shall at all times maintain a long-term unsecured
debt rating of no less than "AA-" from S&P (or "A+" from S&P, if such Fiscal
Agent's short-term unsecured debt rating is at least "A-1" by S&P) and "Aa3"
from Moody's (or, in the case of either Rating Agency, such other rating as
shall not result in an Adverse Rating Event with respect to any Class of
Certificates rated by such Rating Agency, as confirmed in writing by such Rating
Agency).

          (b) To the extent that the Trustee is required, pursuant to the terms
of this Agreement, to make any Advance, whether as successor master servicer or
otherwise, and has failed to do so in accordance with the terms hereof, any
Fiscal Agent appointed by the Trustee shall make such Advance as and when
required by the terms of this Agreement on behalf the Trustee as if such Fiscal
Agent were the Trustee hereunder. To the extent that a Fiscal Agent makes an
Advance pursuant to this Section


                                     -360-



8.17(b) or otherwise pursuant to this Agreement, the obligations of the Trustee
under this Agreement in respect of such Advance shall be satisfied.

          (c) Notwithstanding anything contained in this Agreement to the
contrary, any Fiscal Agent shall be entitled to all limitations on liability,
rights of reimbursement and indemnities that the Trustee is entitled to
hereunder as if it were the Trustee, except that all fees and expenses of any
Fiscal Agent (other than any interest owed to such Fiscal Agent in respect of
unreimbursed Advances) incurred by such Fiscal Agent in connection with the
transactions contemplated by this Agreement shall be borne by the Trustee, and
neither the Trustee nor such Fiscal Agent shall be entitled to reimbursement
therefor from any of the Trust Fund, the Depositor, the Master Servicer or the
Special Servicer.

          (d) The obligations of a Fiscal Agent set forth in this Section 8.17
or otherwise pursuant to this Agreement shall exist only for so long as the
Trustee that appointed it shall act as Trustee hereunder. A Fiscal Agent may
resign or be removed by the Trustee only if and when the existence of such
Fiscal Agent is no longer necessary for such Trustee to satisfy the eligibility
requirements of Section 8.06; provided that a Fiscal Agent shall be deemed to
have resigned at such time as the Trustee that appointed it resigns or is
removed as Trustee hereunder (in which case the responsibility for appointing a
successor Fiscal Agent shall belong to the successor Trustee, and which
appointment the successor Trustee shall use its best efforts to make, insofar as
such appointment is necessary for such successor Trustee to satisfy the
eligibility requirements of Section 8.06). Any successor fiscal agent so
appointed shall be required to execute and deliver to the other parties hereto a
written agreement to assume and perform the duties of a Fiscal Agent set forth
in this Agreement; provided that no such successor shall become Fiscal Agent
hereunder unless either (i) it satisfies the rating requirements of Section
8.17(a) or (ii) the Trustee shall have received written confirmation from each
Rating Agency that the succession of such proposed successor fiscal agent would
not, in and of itself, result in an Adverse Rating Event with respect to any
Class of Certificates.

          (e) The Trustee shall promptly notify the other parties hereto, the
Certificateholders and the Serviced Non-Trust Mortgage Loan Noteholders in
writing of the appointment, resignation or removal of any Fiscal Agent.

          SECTION 8.18.  Representations and Warranties of Fiscal Agent.

          (a) Any Fiscal Agent shall hereby represent and warrant to each of the
other parties hereto and for the benefit of the Certificateholders and the
Serviced Non-Trust Mortgage Loan Noteholders, as of the date of its appointment,
that:

               (i) Such Fiscal Agent is a legal entity duly organized, validly
     existing and in good standing under the laws of the jurisdiction of its
     organization.

     of time, or both, would constitute a default) under, or result in a
     material breach of, any material agreement or other instrument to which it
     is a party or by which it is bound.

               (v) Such Fiscal Agent is not in violation of, and its execution
     and delivery of this Agreement and its performance and compliance with the
     terms of this Agreement will not constitute a violation of, any law, any
     order or decree of any court or arbiter, or any order, regulation or demand
     of any federal, state or local governmental or regulatory authority, which
     violation, in such Fiscal Agent's good faith and reasonable judgment, is

     performance by such Fiscal Agent of or compliance by such Fiscal Agent with
     this Agreement, or the consummation of the transactions contemplated by
     this Agreement, has been obtained and is effective, except where the lack
     of consent, approval, authorization or order would not have a material
     adverse effect on the performance by such Fiscal Agent under this
     Agreement.

provision for payment): (i) to the Certificateholders of all amounts held by or
on behalf of the Trustee and required hereunder to be so paid on the
Distribution Date following the earlier to occur of (A) the purchase by the
Special Servicer, any Controlling Class Certificateholder, the Master Servicer,
the Depositor or Lehman Brothers of all the Trust Mortgage Loans and each REO
Property remaining in the Trust Fund at a price equal to (1) the sum (x) of the
aggregate Purchase Price of all the Trust Mortgage Loans and (y) the aggregate
Appraised Values of any REO Properties then included in the Trust Fund, minus
(2) if the purchaser is the Master Servicer or the Special Servicer, the
aggregate amount of unreimbursed Advances made by such Person, together with any
interest accrued and payable to such Person in respect of unreimbursed Advances
in accordance with Section 3.11(g) and, in the case of the Master Servicer,

with such purchase), (B) the exchange by all the Certificateholders of all the
Certificates for all the Trust Mortgage Loans and each REO Property remaining in
the Trust Fund in the manner set forth below in this Section 9.01 and (C) the

to the Trustee, any Fiscal Agent, the Master Servicer, the Special Servicer and
the members, managers, officers, directors, employees and/or agents of each of
them of all amounts which may have become due and owing to any of them
hereunder; provided, however, that in no event shall the trust created hereby
continue beyond the expiration of 21 years from the death of the last survivor
of the descendants of Joseph P. Kennedy, the late ambassador of the United
States to the Court of St. James, living on the date hereof.

          Following the date on which the aggregate Certificate Principal

Certificates for all of the Trust Mortgage Loans and, subject to the proviso to
the preceding sentence, each REO Property remaining in the Trust Fund, the
Certificateholders, not later than the fifth

and owing to the Depositor, the Master Servicer, the Special Servicer, the
Trustee and the Fiscal Agent pursuant to Section 3.05(a) or Section 3.05A, as

Section 3.05(b), but only to the extent that such amounts are not already on
deposit in such Custodial Account and (ii) pay to the Trustee an amount, in
immediately available funds, equal to $5,000.00. In addition, on the Trust
Master Servicer Remittance Date immediately preceding the Final Distribution
Date, the Master Servicer shall transfer to the Collection Account all amounts
required to be transferred thereto on such Trust Master Servicer Remittance Date
from the Pool Custodial Account pursuant to the first paragraph of Section
3.04(b), together with any other amounts on deposit in the Pool Custodial
Account that would otherwise be held for future distribution. Upon confirmation
that such final deposits have been made and following the surrender of all the
Certificates on the Final Distribution Date, the Trustee shall release or cause
to be released to a designee of all the Certificateholders (each
Certificateholder having agreed to such designation in a writing delivered to
the Trustee), the Mortgage Files for the remaining Trust Mortgage Loans and REO
Properties and shall execute all assignments, endorsements and other instruments
furnished to it by the Certificateholders as shall be necessary to effectuate
transfer of the Trust Mortgage Loans and REO Properties remaining in the Trust
Fund; provided that, if any Trust Mortgage Loan exchanged pursuant to this
Section 9.01 is part of a Loan Combination, then the release, endorsement or
assignment of the documents constituting the related Mortgage File and Servicing
File shall be in the manner contemplated by Section 3.25. Any transfer of Trust
Mortgage Loans pursuant to this paragraph, except in the case of the Outside
Serviced Trust Mortgage Loans, shall be on a servicing-released basis.

          Each of any Controlling Class Certificateholder (with priority among
such Holders being given to the Holder of Certificates representing the greatest
Percentage Interest in the Controlling Class), the Special Servicer, the Master
Servicer, the Depositor or Lehman Brothers, in that order of priority (with the
Controlling Class Certificateholder having the most senior priority), may at its
option elect to purchase all of the Trust Mortgage Loans and each REO Property
remaining in the Trust Fund as contemplated by clause (i) of the preceding
paragraph by giving written notice to the other parties hereto no later than 60
days prior to the anticipated date of purchase; provided, however, that (i) the
aggregate Stated Principal Balance of the Mortgage Pool at the time of such
election is less than 1.0% of the initial aggregate Certificate Principal
Balance of all of the Principal Balance Certificates, and (ii) no such Person
shall have the right to effect such a purchase if, within 30 days following its
delivery of a notice of election pursuant to this paragraph, any other such
Person with a higher priority shall give notice of its election to purchase all
of the Trust Mortgage Loans and each REO Property remaining in the Trust Fund
and shall thereafter effect such purchase in accordance with the terms hereof.
If the Trust Fund is to be terminated in connection with the Special Servicer's,
a Controlling Class Certificateholder's, the Master Servicer's, the Depositor's
or Lehman Brothers' purchase of all of the Trust Mortgage Loans and each REO
Property remaining in the Trust Fund, then the Special Servicer, a Controlling
Class Certificateholder, the Master Servicer, the Depositor or Lehman Brothers,
as applicable, not later than the fifth Business Day preceding the Distribution
Date on which the final distribution on the Certificates is to occur, shall: (x)
deposit, or deliver to the Master Servicer for deposit, in the Pool Custodial
Account an amount in immediately available funds equal to the above-described
purchase price (provided, however, that if any REO Property relating to a
Serviced Loan Combination is being purchased pursuant to the foregoing, the
portion of the above-described purchase price allocable to such REO Property
shall initially be deposited into the related Loan Combination Custodial
Account); and


                                     -364-



(y) deliver to the Trustee an Opinion of Counsel, at the expense of the party
effecting the purchase, stating that the termination of the Trust satisfies the
requirements of a qualified liquidation under Section 860F of the Code and any
regulations thereunder. In addition, on the Trust Master Servicer Remittance
Date immediately preceding the Final Distribution Date, the Master Servicer
shall transfer to the Collection Account all amounts required to be transferred
thereto on such Trust Master Servicer Remittance Date from the Pool Custodial
Account pursuant to the first paragraph of Section 3.04(b), together with any
other amounts on deposit in the Pool Custodial Account that would otherwise be
held for future distribution. Upon confirmation that such final deposits have
been made, the Trustee shall release or cause to be released to the Special
Servicer, the purchasing Controlling Class Certificateholder, the Master
Servicer, the Depositor or Lehman Brothers, as applicable, the Mortgage Files
for the remaining Trust Mortgage Loans and shall execute all assignments,
endorsements and other instruments furnished to it by the Special Servicer, the
purchasing Controlling Class Certificateholder, the Master Servicer, the
Depositor or Lehman Brothers, as applicable, as shall be necessary to effectuate
transfer of the Trust Mortgage Loans and REO Properties to the Special Servicer,
the purchasing Controlling Class Certificateholder, the Master Servicer, the
Depositor or Lehman Brothers (or their respective designees), as applicable;
provided that, if any Trust Mortgage Loan purchased pursuant to this Section
9.01 is a Serviced Combination Trust Mortgage Loan, then the release,
endorsement or assignment of the documents constituting the related Mortgage
File and Servicing File shall be in the manner contemplated by Section 3.25. Any
transfer of Trust Mortgage Loans pursuant to this paragraph, except in the case
of the Outside Serviced Trust Mortgage Loans, shall be on a servicing-released
basis.

          Notice of any termination shall be given promptly by the Trustee by
letter to Certificateholders and the Non-Trust Mortgage Loan Noteholders mailed
(i) if such notice is given in connection with the Special Servicer's, a
Controlling Class Certificateholder's, the Master Servicer's, the Depositor's or
Lehman Brothers' purchase of the Trust Mortgage Loans and each REO Property
remaining in the Trust Fund, not earlier than the 15th day and not later than
the 25th day of the month next preceding the month of the final distribution on
the Certificates or (ii) otherwise during the month of such final distribution
on or before the eighth day of such month, in each case specifying (A) the
Distribution Date upon which the Trust Fund will terminate and final payment of
the Certificates will be made, (B) the amount of any such final payment and (C)
that the Record Date otherwise applicable to such Distribution Date is not
applicable, payments being made only upon presentation and surrender of the
Certificates at the offices of the Certificate Registrar or such other location
therein designated. The Trustee shall give such notice to the Master Servicer,
the Special Servicer and the Depositor at the time such notice is given to
Certificateholders.

          Upon presentation and surrender of the Certificates by the
Certificateholders on the Final Distribution Date, the Trustee shall distribute
to each Certificateholder so presenting and surrendering its Certificates such
Certificateholder's Percentage Interest of that portion of the amounts then on
deposit in the Collection Account and/or the Loss of Value Reserve Fund that
are, in accordance with Section 4.01, allocable to payments on the Class of
Certificates so presented and surrendered.

          Any funds not distributed to any Holder or Holders of Certificates of
any Class on the Final Distribution Date because of the failure of such Holder
or Holders to tender their Certificates shall, on such date, be set aside and
held uninvested in trust and credited to the account or accounts of the
appropriate non-tendering Holder or Holders. If any Certificates as to which
notice has been given pursuant to this Section 9.01 shall not have been
surrendered for cancellation within six months after the


                                     -365-



time specified in such notice, the Trustee shall mail a second notice to the
remaining non-tendering Certificateholders to surrender their Certificates for
cancellation in order to receive the final distribution with respect thereto. If
within one year after the second notice all such Certificates shall not have
been surrendered for cancellation, the Trustee, directly or through an agent,
shall take such reasonable steps to contact the remaining non-tendering
Certificateholders concerning the surrender of their Certificates as it shall
deem appropriate. The costs and expenses of holding such funds in trust and of
contacting such Certificateholders following the first anniversary of the
delivery of such second notice to the non-tendering Certificateholders shall be
paid out of such funds. No interest shall accrue or be payable to any former
Holder on any amount held in trust hereunder. If by the second anniversary of
the delivery of such second notice, all of the Certificates shall not have been
surrendered for cancellation, then, subject to applicable law, the Trustee shall
distribute to the Class R-III Certificateholders all unclaimed funds and other
assets which remain subject hereto.

          SECTION 9.02.  Additional Termination Requirements.

          (a) If the Depositor, Lehman Brothers, any Controlling Class
Certificateholder, the Special Servicer or the Master Servicer purchases, or
there is an exchange of all the Certificates for, all of the Trust Mortgage
Loans and each REO Property remaining in the Trust Fund as provided in Section
9.01, then the Trust Fund (and, accordingly, each REMIC Pool) shall be
terminated in accordance with the following additional requirements, unless the
Person or group of Persons effecting such purchase or exchange obtains at its
own expense and delivers to the Trustee and the Tax Administrator, an Opinion of
Counsel, addressed to the Trustee and the Tax Administrator, to the effect that
the failure of the Trust Fund to comply with the requirements of this Section
9.02 will not result in an Adverse REMIC Event or an Adverse Grantor Trust
Event:

               (i) the Tax Administrator shall specify the first day in the
     90-day liquidation period in a statement attached to the final Tax Return
     for each REMIC Pool pursuant to Treasury regulations section 1.860F-1 and
     shall satisfy all requirements of a qualified liquidation under Section
     860F of the Code and any regulations thereunder as set forth in the Opinion
     of Counsel obtained pursuant to Section 9.01 from the Person or group of
     Persons effecting the purchase of, or exchange of all the Certificates for,
     all the Trust Mortgage Loans and REO Properties remaining in the Trust
     Fund;

               (ii) during such 90-day liquidation period and at or prior to the
     time of making of the final payment on the Certificates, the Trustee shall
     sell or exchange, as applicable, all of the assets of REMIC I and each Loan
     REMIC, if any, to the appropriate Person(s) for cash or the Certificates,
     as applicable; and

               (iii) at the time of the making of the final payment on the
     Certificates, the Trustee shall distribute or credit, or cause to be
     distributed or credited, to the Certificateholders in accordance with
     Sections 4.01 and 9.01 all cash on hand (other than cash retained to meet
     claims), and each REMIC Pool shall terminate at that time.

          In addition, the foregoing requirements of this Section 9.02 shall
apply, mutatis mutandis, to the repurchase of any Early Defeasance Trust
Mortgage Loan and liquidation of any related Loan REMIC if the defeasance
proceeds are less than the Purchase Price of such Early Defeasance Trust
Mortgage Loan, the Mortgagor notifies the Master Servicer of its intent to
defease the Early Defeasance Trust Mortgage Loan or the Mortgagor is to tender
other collateral that does not constitute a cash


                                     -366-



amount equal to or greater than the Purchase Price of the Early Defeasance Trust
Mortgage Loan, under the circumstances described in Sections 2.03(j) and
2.03(k).

          (b) By their acceptance of Certificates, the Holders thereof hereby
agree to authorize the Tax Administrator to specify the 90-day liquidation
period for each REMIC Pool, which authorization shall be binding upon all
successor Certificateholders.

          SECTION 9.03.  Outside Administered REO Properties.

          References to "REO Property" and "REO Properties" in Sections 9.01 and
9.02 shall be deemed to include the Trust's rights with respect to any Outside
Administered REO Property included in the Trust Fund, and such rights shall be
taken into account in calculating the purchase price payable under Section 9.01
for the purchase of assets out of the Trust Fund.


                                     -367-

          SECTION 10.01. REMIC Administration.

          (a) The Tax Administrator shall elect to treat each REMIC Pool as a

hereby designated as "regular interests" (within the meaning of Section
860G(a)(1) of the Code) in REMIC I, REMIC II and REMIC III, respectively. The

meaning of Section 860G(a)(1) of the Code), and the Class R-LR Certificates will
evidence the single class of "residual interests" (within the meaning of Section
860G(a)(2) of the Code, in each Loan REMIC. None of the Master Servicer, the
Special Servicer or the Trustee shall (to the extent within its control) permit
the creation of any other "interests" in any REMIC Pool (within the meaning of
Treasury regulations section 1.860D-1(b)(1)).

          (c) The Closing Date is hereby designated as the "startup day" of each
REMIC Pool within the meaning of Section 860G(a)(9) of the Code.

the applicable taxable year is hereby designated as the Tax Matters Person of
each REMIC Pool, and shall act on behalf of the related REMIC in relation to any
tax matter or controversy and shall represent the related REMIC in any
administrative or judicial proceeding relating to an examination or audit by any
governmental taxing authority; provided that the Tax Administrator is hereby
irrevocably appointed to act and shall act (in consultation with the Tax Matters
Person for each REMIC Pool) as agent and attorney-in-fact for the Tax Matters
Person for each REMIC Pool in the performance of its duties as such.

          (e) For purposes of Treasury regulations section 1.860G-1(a)(4)(iii),
the related Legal Final Distribution Date for each Loan REMIC Regular Interest
(if any), each REMIC I Regular Interest, each REMIC II Regular Interest and each
Class of Regular Interest Certificates (or, in the case of the Interest-Only
Certificates, each REMIC III Component of such Class) is designated in the
Preliminary Statement hereto.

          (f) Except as otherwise provided in Section 3.17(a) and subsections
(i) and (j) below, the Tax Administrator shall pay out of its own funds any and
all routine tax administration expenses of the Trust Fund incurred with respect

Trust Fund that involve the IRS or state tax authorities which extraordinary
expenses shall be payable or


                                     -368-



reimbursable to the Tax Administrator from the Trust Fund (exclusive of any
Grantor Trust Assets), unless otherwise provided in Section 10.01(i) or
10.01(j)).

          (g) Within 30 days after the Closing Date, the Tax Administrator shall
prepare and file with the IRS Form 8811, "Information Return for Real Estate
Mortgage Investment Conduits (REMIC) and Issuers of Collateralized Debt
Obligations" for the Trust Fund. In addition, the Tax Administrator shall
prepare, sign and file all of the other Tax Returns in respect of each REMIC
Pool. The expenses of preparing and filing such returns shall be borne by the
Tax Administrator without any right of reimbursement therefor. The other parties
hereto shall provide on a timely basis to the Tax Administrator or its designee
such information with respect to each REMIC Pool as is in its possession and
reasonably requested by the Tax Administrator to enable it to perform its
obligations under this Section 10.01. Without limiting the generality of the
foregoing, the Depositor, within ten days following the Tax Administrator's
request therefor, shall provide in writing to the Tax Administrator such
information as is reasonably requested by the Tax Administrator for tax
purposes, as to the valuations and issue prices of the Certificates, and the Tax
Administrator's duty to perform its reporting and other tax compliance
obligations under this Section 10.01 shall be subject to the condition that it
receives from the Depositor such information possessed by the Depositor that is
necessary to permit the Tax Administrator to perform such obligations.

          (h) The Tax Administrator shall perform on behalf of each REMIC Pool
all reporting and other tax compliance duties that are the responsibility of
each such REMIC Pool under the Code, the REMIC Provisions or other compliance
guidance issued by the IRS or any state or local taxing authority. Included
among such duties, the Tax Administrator shall provide to: (i) any Transferor of
a Residual Interest Certificate, such information as is necessary for the
application of any tax relating to the transfer of a Residual Interest
Certificate to any Person who is not a Permitted Transferee; (ii) the
Certificateholders, such information or reports as are required by the Code or
the REMIC Provisions, including reports relating to interest, original issue
discount and market discount or premium (using the Prepayment Assumption as
required hereunder); and (iii) the IRS, the name, title, address and telephone
number of the Person who will serve as the representative of each REMIC Pool.
The parties also intend that the portion of the Trust Fund consisting of the
Loss of Value Reserve Fund shall constitute, and the affairs of such portion of
the Trust Fund shall be conducted so as to qualify as, an "outside reserve fund"
within the meaning of Treasury regulations section 1.860G-2(h) and the
provisions hereof shall be interpreted consistently with this intention.

          (i) The Tax Administrator shall perform its duties hereunder so as to
maintain the status of each REMIC Pool as a REMIC under the REMIC Provisions
(and the Trustee, the Master Servicer and the Special Servicer shall assist the
Tax Administrator to the extent reasonably requested by the Tax Administrator
and to the extent of information within the Trustee's, the Master Servicer's or
the Special Servicer's possession or control). None of the Tax Administrator,
the Master Servicer, the Special Servicer or the Trustee shall knowingly take
(or cause any REMIC Pool to take) any action or fail to take (or fail to cause
to be taken) any action that, under the REMIC Provisions, if taken or not taken,
as the case may be, could result in an Adverse REMIC Event, unless the Tax
Administrator has obtained or received an Opinion of Counsel (at the expense of
the party requesting such action or at the expense of the Trust Fund if the Tax
Administrator seeks to take such action or to refrain from acting for the
benefit of the Certificateholders) to the effect that the contemplated action
will not result in an Adverse REMIC Event or an Adverse Grantor Trust Event.
None of the other parties hereto shall take any action or fail to take any
action (whether or not authorized hereunder) as to which the Tax


                                     -369-



Administrator has advised it in writing that the Tax Administrator has received
or obtained an Opinion of Counsel to the effect that an Adverse REMIC Event or
an Adverse Grantor Trust Event could result from such action or failure to act.
In addition, prior to taking any action with respect to any REMIC Pool, or
causing any REMIC Pool to take any action, that is not expressly permitted under
the terms of this Agreement, the Master Servicer and the Special Servicer shall
consult with the Tax Administrator or its designee, in writing, with respect to
whether such action could cause an Adverse REMIC Event or an Adverse Grantor
Trust Event to occur. The Tax Administrator may consult with counsel to make
such written advice, and the cost of same shall be borne by the party seeking to
take the action not permitted by this Agreement, but in no event at the cost or
expense of the Trust Fund or the Trustee. At all times as may be required by the
Code, the Tax Administrator shall make reasonable efforts to ensure that
substantially all of the assets of each REMIC Pool will consist of "qualified
mortgages" as defined in Section 860G(a)(3) of the Code and "permitted
investments" as defined in Section 860G(a)(5) of the Code.

          (j) If any tax is imposed on any REMIC Pool, including "prohibited
transactions" taxes as defined in Section 860F(a)(2) of the Code, any tax on
"net income from foreclosure property" as defined in Section 860G(c) of the
Code, any taxes on contributions to any REMIC Pool after the Startup Day
pursuant to Section 860G(d) of the Code, and any other tax imposed by the Code
or any applicable provisions of State or Local Tax laws (other than any tax
permitted to be incurred by the Special Servicer pursuant to Section 3.17(a)),
such tax, together with all incidental costs and expenses (including penalties
and reasonable attorneys' fees), shall be charged to and paid by: (i) the Tax
Administrator, if such tax arises out of or results from a breach by the Tax
Administrator of any of its obligations under this Section 10.01; (ii) the
Special Servicer, if such tax arises out of or results from a breach by the
Special Servicer of any of its obligations under Article III or this Section
10.01; (iii) the Master Servicer, if such tax arises out of or results from a
breach by the Master Servicer of any of its obligations under Article III or
this Section 10.01; (iv) the Trustee, if such tax arises out of or results from
a breach by the Trustee of any of its obligations under Article IV, Article VIII
or this Section 10.01; (v) the Depositor, if such tax was imposed due to the
fact that any of the Lehman Trust Mortgage Loans did not, at the time of their
transfer to REMIC I or any related Loan REMIC, as applicable, constitute a
"qualified mortgage" as defined in Section 860G(a)(3) of the Code; or (vi) the
Trust Fund, excluding any Grantor Trust Assets, in all other instances. Any tax
permitted to be incurred by the Special Servicer pursuant to Section 3.17(a)
shall be charged to and paid by the Trust Fund (exclusive of any Grantor Trust
Assets). Any such amounts payable by the Trust Fund shall be paid by the Trustee
upon the written direction of the Tax Administrator out of amounts on deposit in
the Collection Account in reduction of the Available Distribution Amount
pursuant to Section 3.05(b).

          (k) The Tax Administrator shall, for federal income tax purposes,
maintain books and records with respect to each REMIC Pool on a calendar year
and on an accrual basis.

          (l) Following the Startup Day, none of the Trustee, the Master
Servicer and the Special Servicer shall accept any contributions of assets to
any REMIC Pool unless it shall have received an Opinion of Counsel (at the
expense of the party seeking to cause such contribution and in no event at the
expense of the Trust Fund or the Trustee) to the effect that the inclusion of
such assets in such REMIC Pool will not cause: (i) such REMIC Pool to fail to
qualify as a REMIC at any time that any Certificates are outstanding; or (ii)
the imposition of any tax on such REMIC Pool under the REMIC Provisions or other
applicable provisions of federal, state and local law or ordinances.


                                     -370-



          (m) None of the Trustee, the Master Servicer and the Special Servicer
shall consent to or, to the extent it is within the control of such Person,
permit: (i) the sale or disposition of any of the Trust Mortgage Loans (except
in connection with (A) the default or reasonably foreseeable material default of
a Trust Mortgage Loan, including, but not limited to, the sale or other
disposition of a Mortgaged Property acquired by deed in lieu of foreclosure, (B)
the bankruptcy of any REMIC Pool, (C) the termination of any REMIC Pool pursuant
to Article IX of this Agreement, or (D) a purchase of Trust Mortgage Loans
pursuant to or as contemplated by Article II or III of this Agreement); (ii) the
sale or disposition of any investments in the Collection Account, the Interest
Reserve Account, the Excess Liquidation Proceeds Account, any Custodial Account
or any REO Account for gain; or (iii) the acquisition of any assets for any
REMIC Pool (other than a Mortgaged Property acquired through foreclosure, deed
in lieu of foreclosure or otherwise in respect of a defaulted Trust Mortgage
Loan and other than Permitted Investments acquired in accordance with Section
3.06 in connection with the investment of funds in a Custodial Account or an REO
Account); in any event unless it has received an Opinion of Counsel (at the
expense of the party seeking to cause such sale, disposition, or acquisition but
in no event at the expense of the Trust Fund or the Trustee) to the effect that
such sale, disposition, or acquisition will not cause: (x) any REMIC Pool to
fail to qualify as a REMIC at any time that any Certificates are outstanding; or
(y) the imposition of any tax on any REMIC Pool under the REMIC Provisions or
other applicable provisions of federal, state and local law or ordinances.

          (n) Except as permitted by Section 3.17(a), none of the Trustee, the
Master Servicer and the Special Servicer shall enter into any arrangement by
which any REMIC Pool will receive a fee or other compensation for services nor
permit any REMIC Pool to receive any income from assets other than "qualified
mortgages" as defined in Section 860G(a)(3) of the Code or "permitted
investments" as defined in Section 860G(a)(5) of the Code.

          SECTION 10.02. Grantor Trust Administration.

          (a) The Tax Administrator shall treat the Grantor Trust, for tax
return preparation purposes, as a grantor trust under the Code and, if
necessary, under applicable state law and will file appropriate federal or state
Tax Returns for each taxable year ending on or after the last day of the
calendar year in which the Certificates are issued.

          (b) The Tax Administrator shall pay out of its own funds any and all
routine tax administration expenses of the Trust Fund incurred with respect to
the Grantor Trust (but not including any professional fees or expenses related
to audits or any administrative or judicial proceedings with respect to the
Trust Fund that involve the IRS or state tax authorities which extraordinary
expenses shall be payable or reimbursable to the Tax Administrator from the
Grantor Trust Assets in the Trust Fund, unless otherwise provided in Section
10.02(e) or 10.02(f)).

          (c) The Tax Administrator shall prepare, sign and file all of the Tax
Returns in respect of the Grantor Trust. The expenses of preparing and filing
such returns shall be borne by the Tax Administrator without any right of
reimbursement therefor. The Tax Administrator shall comply with such requirement
by filing Form 1041, indicating the name and address of the Trust and signed by
the Tax Administrator but otherwise left blank. There shall be appended to each
such form a schedule for each Certificateholder indicating such
Certificateholder's share of income and expenses of the Trust for the portion of
the preceding calendar year in which such Certificateholder possessed an
Ownership Interest in a Certificate. Such form shall be prepared in sufficient
detail to enable reporting on the cash


                                     -371-



or accrual method of accounting, as applicable, and to report on such
Certificateholder's fiscal year if other than the calendar year. The other
parties hereto shall provide on a timely basis to the Tax Administrator or its
designee such information with respect to the Grantor Trust as is in its
possession and reasonably requested by the Tax Administrator to enable it to
perform its obligations under this Section 10.02. Without limiting the
generality of the foregoing, the Depositor, within ten days following the Tax
Administrator's request therefor, shall provide in writing to the Tax
Administrator such information as is reasonably requested by the Tax
Administrator for tax purposes, and the Tax Administrator's duty to perform its
reporting and other tax compliance obligations under this Section 10.02 shall be
subject to the condition that it receives from the Depositor such information
possessed by the Depositor that is necessary to permit the Tax Administrator to
perform such obligations.

          (d) The Tax Administrator shall perform on behalf of the Grantor Trust
all reporting and other tax compliance duties that are required in respect
thereof under the Code, the Grantor Trust Provisions or other compliance
guidance issued by the IRS or any state or local taxing authority, including the
furnishing to Certificateholders of the schedules described in Section 10.01(c).

          (e) The Tax Administrator shall perform its duties hereunder so as to
maintain the status of the Grantor Trust as a grantor trust under the Grantor
Trust Provisions (and the Trustee, the Master Servicer and the Special Servicer
shall assist the Tax Administrator to the extent reasonably requested by the Tax
Administrator and to the extent of information within the Trustee's, the Master
Servicer's or the Special Servicer's possession or control). None of the Tax
Administrator, Master Servicer, the Special Servicer or the Trustee shall
knowingly take (or cause the Grantor Trust to take) any action or fail to take
(or fail to cause to be taken) any action that, under the Grantor Trust
Provisions, if taken or not taken, as the case may be, could result in an
Adverse Grantor Trust Event, unless the Tax Administrator has obtained or
received an Opinion of Counsel (at the expense of the party requesting such
action or at the expense of the Trust Fund if the Tax Administrator seeks to
take such action or to refrain from taking any action for the benefit of the
Certificateholders) to the effect that the contemplated action will not result
in an Adverse Grantor Trust Event. None of the other parties hereto shall take
any action or fail to take any action (whether or not authorized hereunder) as
to which the Tax Administrator has advised it in writing that the Tax
Administrator has received or obtained an Opinion of Counsel to the effect that
an Adverse Grantor Trust Event could result from such action or failure to act.
In addition, prior to taking any action with respect to the Grantor Trust, or
causing the Trust Fund to take any action, that is not expressly permitted under
the terms of this Agreement, the Master Servicer and the Special Servicer shall
consult with the Tax Administrator or its designee, in writing, with respect to
whether such action could cause an Adverse Grantor Trust Event to occur. The Tax
Administrator may consult with counsel to make such written advice, and the cost
of same shall be borne by the party seeking to take the action not permitted by
this Agreement, but in no event at the cost or expense of the Trust Fund, the
Tax Administrator or the Trustee.

          (f) If any tax is imposed on the Grantor Trust, such tax, together
with all incidental costs and expenses (including penalties and reasonable
attorneys' fees), shall be charged to and paid by: (i) the Tax Administrator, if
such tax arises out of or results from a breach by the Tax Administrator of any
of its obligations under this Section 10.02; (ii) the Special Servicer, if such
tax arises out of or results from a breach by the Special Servicer of any of its
obligations under Article III or this Section 10.02; (iii) the Master Servicer,
if such tax arises out of or results from a breach by the Master Servicer of any
of its obligations under Article III or this Section 10.02; (iv) the Trustee, if
such tax arises out of


                                     -372-



or results from a breach by the Trustee of any of its obligations under Article
IV, Article VIII or this Section 10.02; or (v) the portion of the Trust Fund
constituting the Grantor Trust in all other instances.

          (g) Notwithstanding the foregoing provisions of this Section 10.02,
the applicability of this Section 10.02 is subject to Section 2.05(b).


                                     -373-



                                   ARTICLE XI

                            MISCELLANEOUS PROVISIONS

          SECTION 11.01. Amendment.

          (a) This Agreement may be amended from time to time by the mutual
agreement of the parties hereto, without the consent of any of the
Certificateholders or any of the Non-Trust Mortgage Loan Noteholders, (i) to
cure any ambiguity, (ii) to correct, modify or supplement any provision herein
which may be inconsistent with any other provision herein or with the
description thereof in the Prospectus or the Prospectus Supplement, (iii) to add
any other provisions with respect to matters or questions arising hereunder
which shall not be inconsistent with the existing provisions hereof, (iv) to
relax or eliminate any requirement hereunder imposed by the REMIC Provisions or
the Grantor Trust Provisions if those provisions are amended or clarified such
that any such requirement may be relaxed or eliminated, (v) to relax or
eliminate any requirement imposed by the Securities Act or the rules promulgated
thereunder if the Securities Act or those rules are amended or clarified so as
to allow for the relaxation or elimination of that requirement, (vi) as
evidenced by an Opinion of Counsel delivered to the Master Servicer, the Special
Servicer and the Trustee, either (A) to comply with any requirements imposed by
the Code or any successor or amendatory statute or any temporary or final
regulation, revenue ruling, revenue procedure or other written official
announcement or interpretation relating to federal income tax laws or any such
proposed action which, if made effective, would apply retroactively to any of
the REMIC Pools or the Grantor Trust (if created hereunder taking into account
Section 2.05(b)) at least from the effective date of such amendment, or (B) to
avoid the occurrence of a prohibited transaction or to reduce the incidence of
any tax that would arise from any actions taken with respect to the operation of
any REMIC Pool or the Grantor Trust (if created hereunder taking into account
Section 2.05(b)), (vii) as provided in Section 5.02(d)(iv), to modify, add to or
eliminate any of the provisions of Section 5.02(d)(i), (ii) or (iii) hereof,
(viii) to amend any provision of Section 8.15 as contemplated by Section 8.15(n)
hereof, or (ix) to otherwise modify or delete existing provisions of this
Agreement; provided that such amendment (other than any amendment for any of the
specific purposes described in clauses (i), (ii), (iv), (v), (vi), (vii) and
(viii) above) shall not adversely affect in any material respect the interests
of any Certificateholder or Serviced Non-Trust Mortgage Loan Noteholder, as
evidenced by either an Opinion of Counsel delivered to the Trustee and each
other party hereto to such effect, or an acknowledgment to such effect from the
subject Certificateholder or Serviced Non-Trust Mortgage Loan Noteholder, as the
case may be, or, in the case of a Class of Certificates to which a rating has
been assigned by one or more Rating Agencies, written confirmation from each
applicable Rating Agency to the effect that such amendment shall not result in
an Adverse Rating Event with respect to any Class of Certificates; and provided,
further, that such amendment shall not significantly change the activities of
the Trust (insofar as such change would adversely affect the status of the Trust
as a "qualifying special purpose entity" under FASB 140).

          (b) This Agreement may also be amended from time to time by the
agreement of the parties hereto with the consent of the Holders of Certificates
entitled to at least 66-2/3% of the Voting Rights allocated to the affected
Classes for the purpose of adding any provisions to or changing in any manner or
eliminating any of the provisions of this Agreement or of modifying in any
manner the rights of the Holders of Certificates; provided, however, that no
such amendment shall (i) reduce in any manner the amount of, or delay the timing
of, payments received or advanced on Mortgage Loans that


                                     -374-



are required to be distributed on any Certificate, without the consent of the
Holder of such Certificate, or that are required to be distributed to any
Serviced Non-Trust Mortgage Loan Noteholder, without the consent of such
Serviced Non-Trust Mortgage Loan Noteholder, (ii) adversely affect in any
material respect the interests of the Holders of any Class of Certificates or
the interests of any Serviced Non-Trust Mortgage Loan Noteholder in a manner
other than as described in the immediately preceding clause (i), without the
consent of the Holders of all Certificates of such Class or the consent of such
Serviced Non-Trust Mortgage Loan Noteholder, as the case may be, (iii)
significantly change the activities of the Trust (insofar as such change would
adversely affect the status of the Trust as a "qualifying special purpose
entity" under FASB 140) without the consent of the Holders of Certificates
entitled to not less than 51% of all the Voting Rights (without regard to
Certificates held by the Depositor, any Mortgage Loan Seller or any Affiliates
and/or agents of the Depositor or any Mortgage Loan Seller), (iv) modify the
provisions of this Section 11.01, without the consent of the Holders of all
Certificates then outstanding and the consent of all of the Serviced Non-Trust
Mortgage Loan Noteholders, (v) modify the Servicing Standard without the consent
of the Holders of all Regular Interest Certificates then outstanding, or (vi)
modify the specified percentage of Voting Rights which are required to be held
by Certificateholders to consent, approve or object to any particular action
pursuant to any provision of this Agreement without the consent of the Holders
of all Certificates then outstanding. Notwithstanding any other provision of
this Agreement, for purposes of the giving or withholding of consents pursuant
to this Section 11.01(b), Certificates registered in the name of any party
hereto or any Affiliate thereof shall be entitled to the same Voting Rights with
respect to matters described above as they would if any other Person held such
Certificates, so long as the subject amendment does not relate to increasing its
rights or reducing or limiting its obligations hereunder as a party to this
Agreement.

          (c) Notwithstanding any contrary provision of this Agreement, the
Trustee shall not consent to any amendment to this Agreement unless it shall
first have obtained or been furnished with an Opinion of Counsel addressed to
the Trustee and each other party hereto, to the effect that (i) such amendment
or the exercise of any power granted to the Trustee, the Master Servicer or the
Special Servicer in accordance with such amendment will not result in the
imposition of a tax on any REMIC Pool pursuant to the REMIC Provisions, cause
any REMIC Pool to fail to qualify as a REMIC or cause the Grantor Trust (if
created hereunder taking into account Section 2.05(b)) to fail to qualify as a
grantor trust within the meaning of the Grantor Trust Provisions at any time
that any Certificates are outstanding and (ii) such amendment complies in all
material respects with the provisions of this Section 11.01.

          (d) Promptly after the execution of any such amendment, the Trustee
shall send a copy thereof to each Certificateholder and each Serviced Non-Trust
Mortgage Loan Noteholder.

          (e) It shall not be necessary for the consent of Certificateholders
under this Section 11.01 to approve the particular form of any proposed
amendment, but it shall be sufficient if such consent shall approve the
substance thereof. The manner of obtaining such consents and of evidencing the
authorization of the execution thereof by Certificateholders shall be subject to
such reasonable regulations as the Trustee may prescribe.

          (f) Each of the Master Servicer, the Special Servicer and the Trustee
may but shall not be obligated to enter into any amendment pursuant to this
section that affects its rights, duties and immunities under this Agreement or
otherwise.


                                     -375-



          (g) The cost of any Opinion of Counsel to be delivered pursuant to
Section 11.01(a) or (c) shall be borne by the Person seeking the related
amendment, except that if the Master Servicer, the Special Servicer or the
Trustee requests any amendment of this Agreement that protects or is in
furtherance of the rights and interests of Certificateholders, the cost of any
Opinion of Counsel required in connection therewith pursuant to Section 11.01(a)
or (c) shall be payable out of the Pool Custodial Account, in the case of the
Master Servicer and the Special Servicer, pursuant to Section 3.05(a), or out of
the Collection Account, in the case of the Trustee, pursuant to Section 3.05(b).

          SECTION 11.02. Recordation of Agreement; Counterparts.

          (a) To the extent permitted by applicable law, this Agreement is
subject to recordation in all appropriate public offices for real property
records in all the counties or other comparable jurisdictions in which any or
all of the properties subject to the Mortgages are situated, and in any other
appropriate public recording office or elsewhere, such recordation to be
effected by the Master Servicer at the expense of the Trust Fund or, to the
extent that it benefits them, the Serviced Non-Trust Mortgage Loan Noteholders,
but only upon direction accompanied by an Opinion of Counsel (the cost of which
may be paid out of the Pool Custodial Account pursuant to Section 3.05(a) or, to
the extent that it benefits the Serviced Non-Trust Mortgage Loan Noteholders,
out of the Loan Combination Custodial Accounts pursuant to Section 3.05A), to
the effect that such recordation materially and beneficially affects the
interests of the Certificateholders and/or the Serviced Non-Trust Mortgage Loan
Noteholders; provided, however, that the Trustee shall have no obligation or
responsibility to determine whether any such recordation of this Agreement is
required.

          (b) For the purpose of facilitating the recordation of this Agreement
as herein provided and for other purposes, this Agreement may be executed
simultaneously in any number of counterparts, each of which counterparts shall
be deemed to be an original, and such counterparts shall constitute but one and
the same instrument.

          SECTION 11.03. Limitation on Rights of Certificateholders.

          (a) The death or incapacity of any Certificateholder shall not operate
to terminate this Agreement or the Trust Fund, nor entitle such
Certificateholder's legal representatives or heirs to claim an accounting or to
take any action or proceeding in any court for a partition or winding up of the
Trust Fund, nor otherwise affect the rights, obligations and liabilities of the
parties hereto or any of them.

          (b) No Certificateholder (except as expressly provided for herein)
shall have any right to vote or in any manner otherwise control the operation
and management of the Trust Fund, or the obligations of the parties hereto, nor
shall anything herein set forth, or contained in the terms of the Certificates,
be construed so as to constitute the Certificateholders from time to time as
partners or members of an association; nor shall any Certificateholder be under
any liability to any third party by reason of any action taken by the parties to
this Agreement pursuant to any provision hereof.

          (c) No Certificateholder shall have any right by virtue of any
provision of this Agreement to institute any suit, action or proceeding in
equity or at law upon or under or with respect to this Agreement or any Mortgage
Loan, unless, with respect to any suit, action or proceeding upon or under or
with respect to this Agreement, such Person previously shall have given to the
Trustee a written notice of default hereunder, and of the continuance thereof,
as hereinbefore provided, and unless also (except in the case of a default by
the Trustee) the Holders of Certificates entitled to at least 25% of the


                                     -376-



Voting Rights shall have made written request upon the Trustee to institute such
action, suit or proceeding in its own name as Trustee hereunder and shall have
offered to the Trustee such reasonable indemnity as it may require against the
costs, expenses and liabilities to be incurred therein or thereby, and (except
in the case of a default by the Trustee) the Trustee, for 60 days after its
receipt of such notice, request and offer of indemnity, shall have neglected or
refused to institute any such action, suit or proceeding. It is understood and
intended, and expressly covenanted by each Certificateholder with every other
Certificateholder and the Trustee, that no one or more Holders of Certificates
shall have any right in any manner whatsoever by virtue of any provision of this
Agreement to affect, disturb or prejudice the rights of the Holders of any other
of such Certificates, or to obtain or seek to obtain priority over or preference
to any other such Holder, which priority or preference is not otherwise provided
for herein, or to enforce any right under this Agreement, except in the manner
herein provided and for the equal, ratable and common benefit of all
Certificateholders. For the protection and enforcement of the provisions of this
section, each and every Certificateholder and the Trustee shall be entitled to
such relief as can be given either at law or in equity.

          SECTION 11.04. Governing Law; Consent to Jurisdiction.

          This Agreement will be governed by and construed in accordance with
the laws of the State of New York, applicable to agreements negotiated, made and
to be performed entirely in said state. To the fullest extent permitted under
applicable law, the Depositor, the Master Servicer, the Special Servicer, the
Trustee and any Fiscal Agent each hereby irrevocably (i) submits to the
jurisdiction of any New York State and federal courts sitting in New York City,
to the exclusion of all other courts, with respect to matters arising out of or
relating to this Agreement, other than matters to be settled by mediation or
arbitration in accordance with Section 2.03(i); (ii) agrees that all claims with
respect to such action or proceeding shall be heard and determined in such New
York State or federal courts, to the exclusion of all other courts; (iii) waives
the defense of an inconvenient forum in connection with such action or
proceeding commenced in such New York State or federal courts; and (iv) agrees
that a final judgment in any such action or proceeding shall be conclusive and
may be enforced in other jurisdictions by suit on the judgment or in any other
manner provided by law; provided that, if Section 2.03(i) is inapplicable, and
if both a New York State and a federal court sitting in New York in which an
action or proceeding has been duly and properly commenced by any party to this
Agreement regarding a matter arising out of or relating to this Agreement have
refused to accept jurisdiction over or otherwise have not accepted such action
or proceeding within, in the case of each such court, 60 days of the
commencement or filing thereof, then the words "to the exclusion of all other
courts" in clause (i) and clause (ii) of this sentence shall not apply with
regard to such action or proceeding and the reference to "shall" in clause (ii)
of this paragraph shall be deemed to be "may".

          SECTION 11.05. Notices.

          SECTION 11.06. Severability of Provisions.

          If any one or more of the covenants, agreements, provisions or terms
of this Agreement shall be for any reason whatsoever held invalid, then such
covenants, agreements, provisions or terms shall be deemed severable from the
remaining covenants, agreements, provisions or terms of this Agreement and shall
in no way affect the validity or enforceability of the other provisions of this
Agreement or of the Certificates or the rights of the Holders thereof.

          SECTION 11.07. Grant of a Security Interest.

          The Depositor and the Trustee agree that it is their intent that the
conveyance of the Depositor's right, title and interest in and to the Trust
Mortgage Loans pursuant to this Agreement shall constitute a sale and not a
pledge of security for a loan. If such conveyance is deemed to be a pledge of
security for a loan, however, the Depositor and the Trustee agree that it is
their intent that the rights and obligations of the parties to such loan shall
be established pursuant to the terms of this Agreement. The Depositor and the
Trustee also intend and agree that, in such event: (i) in order to secure
performance of the Depositor's obligations hereunder and payment of the
Certificates, the Depositor shall be deemed to have granted, and does hereby
grant, to the Trustee (in such capacity) a first priority security interest in
the Depositor's entire right, title and interest in and to the following
property, whether now owned or existing or hereafter acquired or arising-- (A)
the Trust Mortgage Loans, (B) the UBS/Depositor Mortgage Loan Purchase
Agreement, (C) the respective Co-Lender Agreements, (D) all other assets
included or to be included the Trust Fund, including all principal, interest and
other amounts received or receivable on or with respect to the Trust Mortgage
Loans and due after the Cut-off Date (other than any Principal Prepayments
received on or prior to the Cut-off Date), all amounts (other than those
allocable to the Serviced Non-Trust Mortgage Loans and/or any successor REO
Mortgage Loans with respect thereto) held from time to time in the Custodial
Accounts, the Collection Account, the Interest Reserve Account, the Excess

                                   SCHEDULE I

                          TRUST MORTGAGE LOAN SCHEDULE



                                   SCHEDULE II

                 REPRESENTATIONS AND WARRANTIES OF THE DEPOSITOR

               (i) Trust Mortgage Loan Schedule. The information pertaining to
     such Mortgage Loan set forth in the Trust Mortgage Loan Schedule was true
     and correct in all material respects as of its Cut-off Date.

               (ii) Legal Compliance. If such Mortgage Loan was originated by a
     Lehman Mortgage Loan Seller or another Affiliate of the Depositor, then, as
     of the date of its origination, such Mortgage Loan complied in all material
     respects with, or was exempt from, all requirements of federal, state or
     local law relating to the origination of such Mortgage Loan; and, if such
     Mortgage Loan was not originated by the Lehman Mortgage Loan Seller or
     another Affiliate of the Depositor, then such mortgage loan is listed on
     Schedule III-(ii) and, to the Depositor's actual knowledge, after having
     performed the type of due diligence customarily performed in the
     origination of comparable mortgage loans by the Lehman Mortgage Loan
     Seller, as of the date of its origination, such Mortgage Loan complied in
     all material respects with, or was exempt from, all requirements of
     federal, state or local law relating to the origination of such Mortgage
     Loan.

               (iii) Ownership of Lehman Trust Mortgage Loan. The Depositor owns
     such Mortgage Loan, has good title thereto, has full right, power and
     authority to sell, assign and transfer such Mortgage Loan and is
     transferring such Mortgage Loan free and clear of any and all liens,
     pledges, charges or security interests of any nature encumbering such
     Mortgage Loan, exclusive of the servicing rights pertaining thereto; no
     provision of the Mortgage Note, Mortgage(s) or other loan documents
     relating to such Mortgage Loan prohibits or restricts the Depositor's right
     to assign or transfer such Mortgage Loan to the Trustee (except in the case
     of a Loan Combination, which may, pursuant to the related Co-Lender
     Agreement, require notice to one or more rating agencies or another lender
     which, if required, has already been provided); no governmental or
     regulatory approval or consent is required for the sale of such Mortgage
     Loan by the Depositor; and the Depositor has validly conveyed to the
     Trustee a legal and beneficial interest in and to such Mortgage Loan free
     and clear of any lien, claim or encumbrance of any nature.

               (iv) No Holdback. The proceeds of such Mortgage Loan have been
     fully disbursed (except in those cases where the full amount of such
     Mortgage Loan has been disbursed but a portion thereof is being held in
     escrow or reserve accounts to be released pending the satisfaction of
     certain conditions relating to leasing, repairs or other matters with
     respect to the related Mortgaged Property) and there is no requirement for
     future advances thereunder.

               (v) Loan Document Status. Each of the related Mortgage Note,
     Mortgage(s), Assignment(s) of Leases, if separate from the related
     Mortgage, and other agreements executed in favor of the lender in
     connection therewith is the legal, valid and binding obligation of the
     maker thereof (subject to the non-recourse provisions therein and any state
     anti-deficiency legislation), enforceable in accordance with its terms,
     except that (A) such enforcement may be limited by (1) bankruptcy,
     insolvency, receivership, reorganization, liquidation, voidable preference,
     fraudulent conveyance and transfer, moratorium and/or other similar laws
     affecting the enforcement of creditors' rights generally, and (2) general
     principles of



     equity (regardless of whether such enforcement is considered in a
     proceeding in equity or at law), and (B) certain provisions in the subject
     agreement or instrument may be further limited or rendered unenforceable by
     applicable law, but subject to the limitations set forth in the foregoing
     clause (A), such limitations will not render that subject agreement or
     instrument invalid as a whole or substantially interfere with the
     mortgagee's realization of the principal benefits and/or security provided
     by the subject agreement or instrument. Such Mortgage Loan is non-recourse
     to the Mortgagor or any other Person except to the extent provided in
     certain nonrecourse carveouts and/or in any applicable guarantees. A
     natural person as individual guarantor has agreed, in effect, to be liable
     for all liabilities, costs, losses, damages or expenses suffered or
     incurred by the mortgagee under such Mortgage Loan by reason of or in
     connection with and to the extent of (A) any material intentional fraud or
     material intentional misrepresentation by the related mortgagor; (B) any
     breach on the part of the related mortgagor of any environmental
     representations warranties and covenants contained in the related Mortgage
     Loan documents; (C) misapplication or misappropriation of rents (received
     after an event of default), insurance proceeds or condemnation awards; and
     (D) the filing of a voluntary bankruptcy or insolvency proceeding by the
     related mortgagor; provided that, instead of any breach described in clause
     (B) of this paragraph, such entity (or individual) may instead be liable
     for liabilities, costs, losses, damages, expenses and claims resulting from
     a breach of the obligations and indemnities of the related mortgagor under
     the related Mortgage Loan documents relating to hazardous or toxic
     substances, radon or compliance with environmental laws.

               (vi) No Right of Rescission. Subject to the limitations and
     exceptions as to enforceability set forth in paragraph (v) above, there is
     no valid offset, defense, counterclaim or right of rescission, abatement of
     amounts due under the Mortgage Note or diminution of amounts due under the
     Mortgage Note with respect to any of the related Mortgage Note, Mortgage(s)
     or other agreements executed in connection with such Mortgage Loan and, as
     of the Closing Date, to the actual knowledge of the Depositor, no such
     claim has been asserted.

               (vii) Assignments. The assignment of the related Mortgage(s) and
     Assignment(s) of Leases to the Trustee constitutes the legal, valid,
     binding and, subject to the limitations and exceptions as to enforceability
     set forth in paragraph (v) above, enforceable assignment of such documents
     (provided that the unenforceability of any such assignment based on
     bankruptcy, insolvency, receivership, reorganization, liquidation,
     moratorium and/or other similar laws affecting the enforcement of
     creditors' rights generally or based on general principles of equity
     (regardless of whether such enforcement is considered in a proceeding in
     equity or at law) shall be a breach of this representation and warranty
     only upon the declaration by a court with jurisdiction in the matter that
     such assignment is to be unenforceable on such basis).

               (viii) First Lien. Each related Mortgage is a valid and, subject
     to the limitations and exceptions in paragraph (v) above, enforceable first
     lien on the related Mortgaged Property including all improvements thereon
     (other than any tenant owned improvements) and appurtenances and rights
     related thereto, which Mortgaged Property is free and clear of all
     encumbrances and liens having priority over or on a parity with the first
     lien of such Mortgage, except for the following (collectively, the
     "Permitted Encumbrances"): (A) the lien for real estate taxes, water
     charges, sewer rents and assessments not yet due and payable; (B)
     covenants, conditions and restrictions, rights of way, easements and other
     matters that are of public record or that are omitted as exceptions in the
     related lender's title insurance policy (or, if not yet issued,



     omitted as exceptions in a fully binding pro forma title policy or title
     policy commitment); (C) the rights of tenants (as tenants only) under
     leases (including subleases) pertaining to the related Mortgaged Property;
     (D) condominium declarations of record and identified in the related
     lender's title insurance policy (or, if not yet issued, identified in a pro
     forma title policy or title policy commitment); and (E) if such Lehman
     Trust Mortgage Loan constitutes a Cross-Collateralized Mortgage Loan, the
     lien of the Mortgage for another Mortgage Loan contained in the same
     Cross-Collateralized Group; provided that, in the case of a Lehman Trust
     Mortgage Loan that is part of a Loan Combination, such Mortgage also
     secures the other mortgage loan(s) in such Loan Combination. With respect
     to such Lehman Trust Mortgage Loan, such Permitted Encumbrances do not,
     individually or in the aggregate, materially and adversely interfere with
     the benefits of the security intended to be provided by the related
     Mortgage, the current principal use or operation of the related Mortgaged
     Property or the ability of the related Mortgaged Property to generate
     sufficient cashflow to enable the related Mortgagor to timely pay in full
     the principal and interest on the related Mortgage Note (other than a
     Balloon Payment, which would require a refinancing). If the related
     Mortgaged Property is operated as a nursing facility or a hospitality
     property, the related Mortgage, together with any security agreement,
     chattel mortgage or similar agreement and UCC financing statement, if any,
     establishes and creates a first priority, perfected security interest
     (subject only to any prior purchase money security interest, revolving
     credit lines and any personal property leases), to the extent such security
     interest can be perfected by the recordation of a Mortgage or the filing of
     a UCC financing statement, in all material personal property owned by the
     Mortgagor that is used in, and is reasonably necessary to, the operation of
     the related Mortgaged Property as presently operated by the Mortgagor, and
     that is located on the related Mortgaged Property, which personal property
     includes, in the case of Mortgaged Properties operated by the related
     Mortgagor as a nursing facility or hospitality property, all furniture,
     fixtures, equipment and other personal property located at the subject
     Mortgaged Property that are owned by the related Mortgagor and reasonably
     necessary or material to the operation of the subject Mortgaged Property.
     In the case of any Lehman Trust Mortgage Loan secured by a hotel, the
     related loan documents contain such provisions as are necessary and UCC
     financing statements have been filed as necessary, in each case, to perfect
     a valid first priority security interest, to the extent such security
     interest can be perfected by the inclusion of such provisions and the
     filing of a UCC financing statement, in the Mortgagor's right to receive
     related hotel room revenues with respect to such Mortgaged Property.

               (ix) Taxes and Assessments. All taxes, governmental assessments,
     water charges, sewer rents or similar governmental charges which, in all
     such cases, were directly related to the related Mortgaged Property and
     could constitute liens on the related Mortgaged Property prior to the lien
     of the related Mortgage, together with all ground rents, that prior to the
     related Cut-off Date became due and payable in respect of, and materially
     affect, any related Mortgaged Property have been paid or are escrowed for
     or are not yet delinquent, and the Depositor knows of no unpaid tax,
     assessment, ground rent, water charges or sewer rent, which, in all such
     cases, were directly related to the subject Mortgaged Property and could
     constitute liens on the subject Mortgaged Property prior to the lien of the
     related Mortgage that prior to the Closing Date became due and delinquent
     in respect of any related Mortgaged Property, or in any such case an escrow
     of funds in an amount sufficient to cover such payments has been
     established.



               (x) No Material Damage. As of the date of origination of such
     Mortgage Loan and, to the actual knowledge of the Depositor, as of the
     Closing Date, there was no pending proceeding for the total or partial
     condemnation of any related Mortgaged Property that materially affects the
     value thereof and such Mortgaged Property is free of material damage.
     Except for certain amounts not greater than amounts which would be
     considered prudent by an institutional commercial mortgage lender with
     respect to a similar mortgage loan and which are set forth in the related
     Mortgage or other loan documents relating to such Mortgage Loan, (and
     subject to any rights of the lessor under any related Ground Lease) the
     related Mortgage Loan documents provide that any condemnation awards will
     be applied (or, at the discretion of the mortgagee, will be applied) to
     either the repair or restoration of all or part of the related Mortgaged
     Property or the reduction of the outstanding principal balance of such
     Mortgage Loan.

               (xi) Title Insurance. Each related Mortgaged Property is covered
     by an ALTA (or its equivalent) lender's title insurance policy issued by a
     nationally recognized title insurance company, insuring that each related
     Mortgage is a valid first lien on such Mortgaged Property in the original
     principal amount of such Mortgage Loan (or, if such Mortgage Loan is part
     of a Loan Combination, in the original principal amount of such Loan
     Combination) after all advances of principal, subject only to Permitted
     Encumbrances and, in the case of a Lehman Trust Mortgage Loan that is part
     of a Loan Combination, further subject to the fact that the related
     Mortgage also secures the related Non-Trust Mortgage Loan(s) (or, if such
     policy has not yet been issued, such insurance may be evidenced by a
     binding commitment or binding pro forma marked as binding and signed
     (either thereon or on a related escrow letter attached thereto) by the
     title insurer or its authorized agent) from a title insurer qualified
     and/or licensed in the applicable jurisdiction, as required, to issue such
     policy; such title insurance is in full force and effect, all premiums have
     been paid, is freely assignable and will inure to the benefit of the
     Trustee as sole insured as mortgagee of record, or any such commitment or
     binding pro forma is a legal, valid and binding obligation of such insurer;
     no claims have been made by the Depositor, the applicable Lehman Mortgage
     Loan Seller or any prior holder of such Mortgage Loan (other than a prior
     holder unaffiliated with the Depositor or the applicable Lehman Mortgage
     Loan Seller from whom the Depositor or the applicable Lehman Mortgage Loan
     Seller has taken by assignment) under such title insurance; and neither the
     Depositor nor the applicable Lehman Mortgage Loan Seller (or any of its
     Affiliates) has done, by act or omission, anything that would materially
     impair the coverage of any such title insurance policy; such policy or
     commitment or binding pro forma contains no exclusion for (or alternatively
     it insures over such exclusion, unless such coverage is unavailable in the
     relevant jurisdiction) (A) access to a public road, (B) that there is no
     material encroachment by any improvements on the related Mortgaged Property
     either to or from any adjoining property or across any easements on the
     related Mortgaged Property, and (C) that the land shown on the survey
     materially conforms to the legal description of the related Mortgaged
     Property.

               (xii) Property Insurance. As of the date of its origination and,
     to the Depositor's actual knowledge, as of the Cut-off Date, all insurance
     required under each related Mortgage (except where an investment grade
     tenant, or one or more tenants which in the aggregate do not represent more
     than 10% of the net operating income with respect to the entire related
     Mortgaged Property, is or are permitted to insure or self-insure under a
     lease) was in full force and effect with respect to each related Mortgaged
     Property; such insurance included (A) fire and extended perils insurance
     included within the classification "All Risk of Physical



     Loss" or the equivalent thereof in an amount (subject to a customary
     deductible) at least equal to the lesser of (1) 100% of the full insurable
     value of the improvements located on such Mortgaged Property and (2) the
     outstanding principal balance of such Mortgage Loan or the portion thereof
     allocable to such Mortgaged Property) and, if applicable, the related
     hazard insurance policies or certificates of insurance contain appropriate
     endorsements to avoid application of co-insurance, (B) business
     interruption or rental loss insurance for a period of not less than 12
     months, (C) comprehensive general liability insurance in an amount not less
     than $1 million per occurrence, (D) workers' compensation insurance (if the
     related Mortgagor has employees and if required by applicable law), and (E)
     if (1) such Mortgage Loan is secured by a Mortgaged Property located in the
     State of California or in "seismic zone" 3 or 4 and (2) a seismic
     assessment as described below revealed a maximum probable or bounded loss
     in excess of 20% of the amount of the estimated replacement cost of the
     improvements on such Mortgaged Property, seismic insurance; it is an event
     of default under such Mortgage Loan if the above-described insurance
     coverage is not maintained by the related Mortgagor (except where an
     investment grade tenant, or one or more tenants which in the aggregate do
     not represent more than 10% of the net operating income with respect to the
     entire related Mortgaged Property, is or are permitted to insure or
     self-insure under a lease) and the related loan documents provide (in
     either a general cost and expense recovery provision or a specific
     provision with respect to recovery of insurance costs and expenses) that
     any reasonable out-of-pocket costs and expenses incurred by the mortgagee
     in connection with such default in obtaining such insurance coverage may be
     recovered from the related Mortgagor; the related Evidence of Property
     Insurance and certificate of liability insurance (which may be in the form
     of an Acord 27 or an Acord 25, respectively), or forms substantially
     similar thereto, provide that the related insurance policy may not be
     terminated or reduced without at least 10 days prior notice to the
     mortgagee and (other than those limited to liability protection) name the
     mortgagee and its successors as loss payee; no notice of termination or
     cancellation with respect to any such insurance policy has been received by
     the Depositor or the applicable Lehman Mortgage Loan Seller or, to the
     actual knowledge of the Depositor, by any prior mortgagee under such
     Mortgage Loan (other than, with respect to a related Mortgaged Property
     located in New York and Florida, a prior mortgagee unaffiliated with the
     Depositor or the applicable Lehman Mortgage Loan Seller from whom the
     Depositor or the applicable Lehman Mortgage Loan Seller has taken the
     related Mortgage Note and Mortgage by assignment and has amended and
     restated such Mortgage Note and Mortgage); all premiums under any such
     insurance policy have been paid through the Cut-off Date; the insurance
     policies specified in clauses (A), (B) and (C) above are required to be
     maintained with insurance companies having "financial strength" or "claims
     paying ability" ratings of at least "A:VII" from A.M. Best Company or at
     least "BBB+" (or equivalent) from a nationally recognized statistical
     rating agency (or, with respect to certain blanket insurance policies, such
     other ratings as are in compliance with S&P's applicable criteria for
     rating the Certificates); and, except for certain amounts not greater than
     amounts which would be considered prudent by an institutional commercial
     mortgage lender with respect to a similar mortgage loan and which are set
     forth in the related Mortgage or other loan documents relating to such
     Mortgage Loan, and subject to the related exception schedules, the related
     Mortgage Loan documents provide that any property insurance proceeds will
     be applied (or, at the discretion of the mortgagee, will be applied) either
     to the repair or restoration of all or part of the related Mortgaged
     Property or the reduction of the outstanding principal balance of such
     Mortgage Loan; provided that the related Mortgage Loan documents may
     entitle the related Mortgagor to any portion of such proceeds remaining
     after completion of the repair or restoration of the related Mortgaged
     Property or payment of amounts due under such Mortgage Loan. With respect
     to the subject Mortgage Loan, the related loan



     documents generally require the Mortgagor to maintain insurance against
     windstorm damage and certain acts of terrorism (except where an investment
     grade tenant is permitted to insure or self-insure under a lease or is
     required to restore the premises, and except where a related sponsor has
     agreed to be responsible for losses due to windstorm or certain acts of
     terrorism, as the case may be, which would have otherwise been covered by
     insurance); provided, that any such insurance and the amount thereof may be
     limited by the commercial availability of such coverage, whether the
     mortgagee may reasonably require such insurance, certain limitations with
     respect to the cost thereof and/or whether such hazards are at the time
     commonly insured against for property similar to the related Mortgaged
     Property; and provided, further, that with respect to windstorm damage,
     such insurance is only required if the related Mortgaged Property is
     located within 25 miles of the coast of Florida, North Carolina, South
     Carolina, Georgia, Alabama, Mississippi, Louisiana or Texas. If the related
     Mortgaged Property is located in the State of California or in "seismic
     zone" 3 or 4, then: (A) either a seismic assessment was conducted with
     respect to the related Mortgaged Property in connection with the
     origination of such Mortgage Loan or earthquake insurance was obtained; and
     (B) the probable maximum loss for the related Mortgaged Property as
     reflected in such seismic assessment, if any, was determined based upon a
     return period of not less than 475 years, an exposure period of 50 years
     and a 10% probability of incidence. Schedule III-(xii) attached hereto is
     true and correct in all material respects.

               (xiii) No Material Defaults. Other than payments due but not yet
     30 days or more delinquent, there is (A) no material default, breach,
     violation or event of acceleration existing under the related Mortgage
     Note, the related Mortgage or other loan documents relating to such
     Mortgage Loan, and (B), to the knowledge of the Depositor as of the Closing
     Date, no event which, with the passage of time or with notice and the
     expiration of any grace or cure period, would constitute a material
     default, breach, violation or event of acceleration under any of such
     documents; provided, however, that this representation and warranty does
     not cover any default, breach, violation or event of acceleration (A) that
     specifically pertains to or arises out of the subject matter otherwise
     covered by any other representation and warranty made by the Depositor in
     this Schedule II or (B) with respect to which: (1) neither the Depositor
     nor the applicable Lehman Mortgage Loan Seller has any actual knowledge as
     of the Closing Date and (2) written notice of the discovery thereof is not
     delivered to the Depositor by the Trustee or the Master Servicer on or
     prior to the date occurring 12 months after the Closing Date. None of the
     Depositor, the applicable Lehman Mortgage Loan Seller or any prior holder
     of such Mortgage Loan (other than, with respect to a related Mortgaged
     Property located in New York and Florida, a prior holder unaffiliated with
     the Depositor or the applicable Lehman Mortgage Loan Seller from whom the
     Depositor or the applicable Lehman Mortgage Loan Seller has taken the
     related Mortgage Note and Mortgage by assignment and has amended and
     restated such Mortgage Note and Mortgage) has waived, in writing or with
     knowledge, any material default, breach, violation or event of acceleration
     under any of such documents. Under the terms of such Mortgage Loan, no
     person or party other than the mortgagee or its servicing agent may declare
     an event of default or accelerate the related indebtedness under such
     Mortgage Loan.

               (xiv) No Payment Delinquency. As of the Closing Date, such
     Mortgage Loan is not, and in the prior 12 months (or since the date of
     origination if such Mortgage Loan has been originated within the past 12
     months), has not been, 30 days or more past due in respect of any Monthly
     Payment.



               (xv) Interest Accrual Basis. Such Mortgage Loan accrues interest
     on an Actual/360 Basis, an Actual/Actual Basis or a 30/360 Basis; and such
     Mortgage Loan accrues interest (payable monthly in arrears) at a fixed rate
     of interest throughout the remaining term thereof (except if such Mortgage
     Loan is an ARD Mortgage Loan, in which case the accrual rate for interest
     will increase after its Anticipated Repayment Date, and except in
     connection with the occurrence of a default and the accrual of default
     interest).

               (xvi) Subordinate Debt. Each related Mortgage or other loan
     document relating to such Mortgage Loan does not provide for or permit,
     without the prior written consent of the holder of the related Mortgage
     Note, any related Mortgaged Property or any direct controlling interest in
     the Mortgagor to secure any other promissory note or debt (other than
     another Mortgage Loan in the Trust Fund and, if such Mortgage Loan is part
     of a Loan Combination, the other mortgage loan(s) that are part of such
     Loan Combination, as applicable).

               (xvii) Qualified Mortgage. Such Mortgage Loan is "qualified
     mortgage" within the meaning of Section 860G(a)(3) of the Code.
     Accordingly, either as of the date of origination or the Closing Date, the
     fair market value of the real property securing such Mortgage Loan was not
     less than 80% of the "adjusted issue price" (within the meaning of the
     REMIC Provisions) of such Mortgage Loan. For purposes of the preceding
     sentence, the fair market value of the real property securing such Mortgage
     Loan was first reduced by the amount of any lien on such real property that
     is senior to the lien that secures such Mortgage Loan, and was further
     reduced by a proportionate amount of any lien that is on a parity with the
     lien that secures such Mortgage Loan. No action that occurs by operation of
     the terms of such Mortgage Loan would cause such Mortgage Loan to cease to
     be a "qualified mortgage" and such Mortgage Loan does not permit the
     release or substitution of collateral if such release or substitution (A)
     would constitute a "significant modification" of such Mortgage Loan within
     the meaning of Treasury regulations section 860G-2(b), (B) would cause such
     Mortgage Loan not to be a "qualified mortgage" within the meaning of
     Section 860G(a)(3) of the Code (without regard to clauses (A)(i) or (A)(ii)
     thereof) or (C) would cause a "prohibited transaction" within the meaning
     of Section 860F(a)(2) of the Code. The related Mortgaged Property, if
     acquired in connection with the default or imminent default of such
     Mortgage Loan, would constitute "foreclosure property" within the meaning
     of Section 860G(a)(8) of the Code.

               (xviii) Prepayment Consideration. Prepayment Premiums and Yield
     Maintenance Charges payable with respect to such Mortgage Loan, if any,
     constitute "customary prepayment penalties" within the meaning of Treasury
     regulations section 1.860G-1(b)(2).

               (xix) Environmental Conditions. One or more environmental site
     assessments (or updates thereof) in each instance meeting American Society
     of Testing and Materials requirements were performed by an environmental
     consulting firm independent of the Depositor and the Depositor's Affiliates
     with respect to each related Mortgaged Property during the 12-month period
     preceding the Cut-off Date, and the Depositor, having made no independent
     inquiry other than to review the report(s) prepared in connection with the
     assessment(s) and/or update(s) referenced herein, has no knowledge of, and
     has not received actual notice of, any material and adverse environmental
     condition or circumstance affecting such Mortgaged Property that was not
     disclosed in such report(s); and none of the environmental reports reveal
     any circumstances or conditions that are in violation of any applicable
     environmental laws, or if such report does reveal such circumstances, then
     (1) the same have been remediated in all



     material respects, (2) sufficient funds have been escrowed or a letter of
     credit, guaranty or other instrument has been delivered for purposes of
     covering the estimated costs of such remediation, (3) the related Mortgagor
     or other responsible party set forth on Schedule I (which Mortgagor or
     other responsible party has been reasonably determined by the Depositor or
     the applicable Lehman Mortgage Loan Seller to have the creditworthiness to
     do so (such determination by the Depositor or the applicable Lehman
     Mortgage Loan Seller to be based on review of (i) the financial statements
     provided to the Depositor or the applicable Lehman Mortgage Loan Seller by
     the Mortgagor or other responsible party, as applicable, and (ii) the
     reasonable cost of remediation of the circumstances or conditions that are
     in violation of the applicable environmental laws as set forth in the
     applicable environmental report)) is currently taking remedial or other
     appropriate action to address the environmental issue consistent with the
     recommendations in such site assessment, (4) the cost of the environmental
     issue relative to the value of such Mortgaged Property was de minimis, or
     (5) environmental insurance has been obtained.

               The Mortgagor with respect to such Mortgage Loan has represented,
     warranted and covenanted generally to the effect that, to its knowledge,
     except as set forth in the environmental reports described above, it has
     not used, caused or permitted to exist, and will not use, cause or permit
     to exist, on the related Mortgaged Property, any Hazardous Materials in any
     manner which violates applicable federal, state or local laws governing the
     use, storage, handling, production or disposal of Hazardous Materials at
     the related Mortgaged Property and (A) the related Mortgagor and a natural
     person have agreed to indemnify the mortgagee under such Mortgage Loan, and
     its successors and assigns, against any losses, liabilities, damages,
     penalties, fines, claims and reasonable out of pocket expenses (excluding
     lost profits, consequential damages and diminution of value of the related
     Mortgaged Property, provided that no Lehman Trust Mortgage Loan with an
     original principal balance equal to or greater than $15,000,000 contains an
     exclusion for "diminution of value" of the related Mortgaged Property)
     paid, suffered or incurred by such mortgagee resulting from such
     Mortgagor's material violation of any environmental law or a material
     breach of the environmental representations and warranties or covenants
     given by the related Mortgagor in connection with such Mortgage Loan or (B)
     environmental insurance has been obtained. If such Mortgage Loan is a
     Mortgage Loan as to which neither a natural person has provided the
     indemnity set forth above nor environmental insurance has been obtained,
     such Mortgage Loan is set forth on Schedule III-(xix).

               The Depositor has not taken any action with respect to such
     Mortgage Loan or the related Mortgaged Property that could subject the
     Depositor or its successors and assigns in respect of such Mortgage Loan to
     liability under CERCLA or any other applicable federal, state or local
     environmental law. The related Mortgage or other loan documents require the
     related Mortgagor to comply with all applicable federal, state and local
     environmental laws and regulations.

               (xx) Realization Against Real Estate Collateral. The related
     Mortgage Note, Mortgage(s), Assignment(s) of Leases and other loan
     documents securing such Mortgage Loan, if any, contain customary and,
     subject to the limitations and exceptions as to enforceability in paragraph
     (v) above, enforceable provisions such as to render the rights and remedies
     of the holder thereof adequate for the practical realization against the
     related Mortgaged Property or



     Properties of the principal benefits of the security intended to be
     provided thereby, including realization by judicial or, if applicable,
     non-judicial foreclosure.

               (xxi) Bankruptcy. The related Mortgagor is not a debtor in any
     bankruptcy, reorganization, insolvency or comparable proceeding; provided,
     however, that this representation and warranty does not cover any such
     bankruptcy, reorganization, insolvency or comparable proceeding with
     respect to which: (1) neither the Depositor nor the applicable Lehman
     Mortgage Loan Seller has any actual knowledge and (2) written notice of the
     discovery thereof is not delivered to the Depositor by the Trustee or the
     Master Servicer on or prior to the date occurring twelve months after the
     Closing Date.

               (xxii) Loan Security. Such Mortgage Loan is secured by a Mortgage
     on a fee simple interest and/or a leasehold estate in a commercial property
     or multifamily property, including the related Mortgagor's interest in the
     improvements on the related Mortgaged Property.

               (xxiii) Amortization. Such Mortgage Loan does not provide for
     negative amortization unless such Mortgage Loan is an ARD Mortgage Loan, in
     which case it may occur only after the Anticipated Repayment Date.

               (xxiv) Whole Loan. Such Mortgage Loan is a whole loan, contains
     no equity participation by the lender or shared appreciation feature and
     does not provide for any contingent interest in the form of participation
     in the cash flow of the related Mortgaged Property.

               (xxv) Due-on-Encumbrance. Each Lehman Trust Mortgage Loan
     contains provisions for the acceleration of the payment of the unpaid
     principal balance of such Mortgage Loan if, without the prior written
     consent of the mortgagee or Rating Agency confirmation that an Adverse
     Rating Event with respect to any Class of Certificates would not occur, any
     related Mortgaged Property or any direct controlling interest in the
     Mortgagor is directly encumbered in connection with subordinate financing;
     and, except in the case of a Lehman Trust Mortgage Loan that is part of a
     Loan Combination (for which such consent has been granted with respect to
     the other mortgage loan(s) in such Loan Combination), and except for the
     respective Lehman Trust Mortgage Loans secured by the Mortgaged Properties
     listed on Schedule III-(xxv) (for which such consent has been granted with
     respect to mezzanine debt), no such consent has been granted by the
     applicable Lehman Mortgage Loan Seller. To the Depositor's knowledge, no
     related Mortgaged Property is encumbered in connection with subordinate
     financing (except that each Mortgaged Property securing a Lehman Trust
     Mortgage Loan that is part of a Loan Combination also secures the other
     mortgage loan(s) in such Loan Combination); however, if the related
     Mortgaged Property is listed on Schedule III-(xxv), then certain direct
     controlling equity holders in the related Mortgagor are known to the
     Depositor to have incurred debt secured by their ownership interest in the
     related Mortgagor.

               (xxvi) Due-on-Sale. Except with respect to transfers of certain
     non-controlling and/or minority interests in the related Mortgagor as
     specified in the related Mortgage or with respect to transfers of interests
     in the related Mortgagor between immediate family members and with respect
     to transfers by devise, by descent or by operation of law or otherwise upon
     the death or incapacity of a person having an interest in the related
     Mortgagor, each Lehman Trust Mortgage Loan contains either (A) provisions
     for the acceleration of the payment of the unpaid principal balance of such
     Mortgage Loan if any related Mortgaged Property or interest therein is



     directly or indirectly transferred or sold without the prior written
     consent of the mortgagee or rating agency confirmation, or (B) provisions
     for the acceleration of the payment of the unpaid principal balance of such
     Mortgage Loan if any related Mortgaged Property or interest therein is
     directly or indirectly transferred or sold without the related Mortgagor
     having satisfied certain conditions specified in the related Mortgage with
     respect to permitted transfers (which conditions are consistent with the
     practices of prudent commercial mortgage lenders (as defined below)). The
     Mortgage (under either specific or general expense provisions) requires the
     Mortgagor to pay all reasonable fees and expenses associated with securing
     the consent or approval of the holder of the Mortgage for all actions
     involving the transfer of interest in such Mortgagor requiring such consent
     or approval under the Mortgage.

               (xxvii) Mortgagor Concentration. Except in the case of the Trust
     Mortgage Loans listed on Schedule III (xxvii), such Mortgage Loan, together
     with any other Lehman Trust Mortgage Loan made to the same Mortgagor or to
     an Affiliate of such Mortgagor, does not represent more than 5% of the
     Initial Pool Balance.

               (xxviii) Waivers; Modifications. Except as set forth in a written
     instrument included in the related Mortgage File, the (A) material terms of
     the related Mortgage Note, the related Mortgage(s) and any related loan
     agreement and/or lock-box agreement have not been waived, modified,
     altered, satisfied, impaired, canceled, subordinated or rescinded by the
     mortgagee in any manner, and (B) no portion of a related Mortgaged Property
     has been released from the lien of the related Mortgage, in the case of (A)
     and/or (B), to an extent or in a manner that in any such event materially
     interferes with the security intended to be provided by such document or
     instrument. Schedule III (xxviii) identifies each Mortgage Loan (if any) as
     to which, since the latest date any related due diligence materials were
     delivered to American Capital Strategies Ltd. (or its designee), there has
     been (in writing) given, made or consented to a material alteration,
     material modification or assumption of the terms of the related Mortgage
     Note, Mortgage(s) or any related loan agreement and/or lock-box agreement
     and/or as to which, since such date, there has been (in writing) a waiver
     other than as related to routine operational matters or minor covenants.

               (xxix) Inspection. Each related Mortgaged Property was inspected
     by or on behalf of the related originator during the six-month period prior
     to the related origination date.

               (xxx) Property Release. The terms of the related Mortgage Note,
     Mortgage(s) or other loan document securing such Mortgage Loan do not
     provide for the release from the lien of such Mortgage of any material
     portion of the related Mortgaged Property that is necessary to the
     operation of such Mortgaged Property or was given material value in the
     underwriting of such Mortgage Loan at origination, without (A) payment in
     full of such Mortgage Loan, (B) delivery of Defeasance Collateral in the
     form of "government securities" within the meaning of Section 2(a)(16) of
     the Investment Company Act of 1940, as amended (the "Investment Company
     Act"), (C) payment of a release price equal to at least 125% of the amount
     of such Mortgage Loan allocated to the related Mortgaged Property subject
     to the release or (D) with respect to mortgage loans listed on Schedule
     III-(xxx), the satisfaction of certain underwriting and legal requirements
     which the applicable Lehman Mortgage Loan Seller required in the
     origination of comparable mortgage loans.



               (xxxi) Qualifications; Licensing; Zoning. The related Mortgagor
     has covenanted in the related Mortgage Loan documents to maintain the
     related Mortgaged Property in compliance in all material respects with, to
     the extent it is not grandfathered under, all applicable laws, zoning
     ordinances, rules, covenants and restrictions affecting the construction,
     occupancy, use and operation of such Mortgaged Property, and the related
     originator performed the type of due diligence in connection with the
     origination of such Mortgage Loan customarily performed by prudent
     commercial mortgage lenders (as defined below) with respect to the
     foregoing matters; the Depositor has received no notice of any material
     violation of, to the extent is has not been grandfathered under, any
     applicable laws, zoning ordinances, rules, covenants or restrictions
     affecting the construction, occupancy, use or operation of the related
     Mortgaged Property (unless affirmatively covered by the title insurance
     referred to in paragraph (xi) above (or an endorsement thereto)); to the
     Depositor's knowledge (based on surveys, opinions, letters from
     municipalities and/or title insurance obtained in connection with the
     origination of such Mortgage Loan), no improvement that was included for
     the purpose of determining the appraised value of the related Mortgaged
     Property at the time of origination of such Mortgage Loan lay outside the
     boundaries and building restriction lines of such property, in effect at
     the time of origination of such Mortgage Loan, to an extent which would
     have a material adverse affect on the related Mortgagor's use and operation
     of such Mortgaged Property (unless grandfathered with respect thereto or
     affirmatively covered by the title insurance referred to in paragraph (xi)
     above (or an endorsement thereto)), and no improvements on adjoining
     properties encroached upon such Mortgaged Property to any material extent.
     For purposes of this paragraph, a Mortgaged Property shall be deemed
     "grandfathered" with respect to any laws, zoning ordinances, rules,
     covenants or restrictions affecting the construction, occupancy, use or
     operation of the related Mortgaged Property, if and to the extent that any
     of the construction, occupancy, use and operation of such Mortgaged
     Property: (A) conformed in all material respects with such laws, zoning
     ordinances, rules, covenants and restrictions affecting the improvements on
     the related Mortgaged Property at the time the improvements on the related
     Mortgaged Property were initially constructed or put into operation; and/or
     (B) was not addressed or otherwise prohibited by any such laws, zoning
     ordinances, rules, covenants and restrictions affecting the related
     Mortgaged Property at the time the improvements on the related Mortgaged
     Property were initially constructed or put into operation.

               (xxxii) Property Financial Statements. The related Mortgagor has
     covenanted in the related Mortgage Loan documents to deliver to the
     mortgagee annual operating statements, rent rolls and related information
     of each related Mortgaged Property and annual financial statements. If such
     Mortgage Loan had an original principal balance greater than $15 million,
     the related Mortgagor has covenanted to provide such operating statements,
     rent rolls and related information on a quarterly basis. If such Mortgage
     Loan has an original principal balance equal to or greater than $20
     million, the related Mortgagor, if it obtains an audited financial
     statement, is required to provide a copy thereof to the holder of such
     Mortgage Loan at the related mortgagee's request.

               (xxxiii) Single Purpose Entity. If such Mortgage Loan has a
     Cut-off Date Balance in excess of $25 million, then the related Mortgagor
     is obligated by its organizational documents and the related Mortgage Loan
     documents to be a Single Purpose Entity for so long as such Mortgage Loan
     is outstanding; and, if such Mortgage Loan has a Cut-off Date Balance
     greater than $5 million and less than $25 million, then the related
     Mortgagor is obligated by its organizational documents and/or the related
     Mortgage Loan documents to own the related



     Mortgaged Property and no other material assets, except such as are
     incidental to the ownership of such Mortgaged Property for so long as such
     Mortgage Loan is outstanding. For purposes of this representation, "Single
     Purpose Entity" means an entity whose organizational documents or the
     related Mortgage Loan documents provide substantially to the effect that
     such entity: (A) is formed or organized solely for the purpose of owning
     and operating one or more of the Mortgaged Properties securing such
     Mortgage Loan, (B) may not engage in any business unrelated to the related
     Mortgaged Property or Mortgaged Properties, (C) does not have any material
     assets other than those related to its interest in and operation of such
     Mortgaged Property or Mortgaged Properties and (D) may not incur
     indebtedness other than as permitted by the related Mortgage or other
     Mortgage Loan documents. If such Mortgage Loan has an initial principal
     balance of $25 million and above and the related Mortgagor is a single
     member limited liability company, such Mortgagor's organizational documents
     provide that such Mortgagor shall not dissolve or liquidate upon the
     bankruptcy, dissolution, liquidation or death of its sole member and is
     organized in a jurisdiction that provides for such continued existence and
     there was obtained opinion of counsel confirming such continued existence.
     If such Mortgage Loan has, or is part of a group of Lehman Trust Mortgage
     Loans with affiliated Mortgagors having, a Cut-off Date Balance equal to or
     greater than 2% of the Initial Pool Balance, or if such Mortgage Loan has
     an original principal balance equal to or greater than $25 million, there
     was obtained an opinion of counsel regarding non-consolidation of such
     Mortgagor.

               (xxxiv) Advancing of Funds. No advance of funds has been made,
     directly or indirectly, by the originator or the Depositor to the related
     Mortgagor other than pursuant to the related Mortgage Note; and, to the
     actual knowledge of the Depositor, no funds have been received from any
     Person other than such Mortgagor for or on account of payments due on the
     related Mortgage Note.

               (xxxv) Legal Proceedings. To the Depositor's actual knowledge,
     there are no pending actions, suits or proceedings by or before any court
     or governmental authority against or affecting the related Mortgagor or any
     related Mortgaged Property that, if determined adversely to such Mortgagor
     or Mortgaged Property, would materially and adversely affect the value of
     such Mortgaged Property or the ability of such Mortgagor to pay principal,
     interest or any other amounts due under such Mortgage Loan.

               (xxxvi) Originator Duly Authorized. To the extent required under
     applicable law as of the Closing Date, the originator of such Mortgage Loan
     was qualified and authorized to do business in each jurisdiction in which a
     related Mortgaged Property is located at all times when it held such
     Mortgage Loan to the extent necessary to ensure the enforceability of such
     Mortgage Loan.

               (xxxvii) Trustee under Deed of Trust. If the related Mortgage is
     a deed of trust, a trustee, duly qualified under applicable law to serve as
     such, is properly designated and serving under such Mortgage, and no fees
     and expenses are payable to such trustee except in connection with a
     trustee sale of the related Mortgaged Property following a default or in
     connection with the release of liens securing such Mortgage Loan and any
     such fees and expenses are the obligation of the Mortgagor under the terms
     of the Mortgage.

               (xxxviii) Cross-Collateralization. The related Mortgaged Property
     is not, to the Depositor's knowledge, collateral or security for any
     mortgage loan that is not in the Trust Fund



     and, if such Mortgage Loan is cross-collateralized, it is
     cross-collateralized only with other Mortgage Loans in the Trust Fund,
     except that a Lehman Trust Mortgage Loan that is part of a Loan Combination
     is secured by one or more Mortgaged Properties that also secure the related
     Non-Trust Mortgage Loan(s). The security interest/lien on each material
     item of collateral for such Mortgage Loan has been assigned to the Trustee.

               (xxxix) Flood Hazard Insurance. None of the improvements on any
     related Mortgaged Property are located in a flood hazard area as defined by
     the Federal Insurance Administration or, if any portion of the improvements
     on the related Mortgaged Property are in an area identified in the Federal
     Register by the Federal Emergency Management Agency as having special flood
     hazards falling within zones A or V in the national flood insurance
     program, the Mortgagor has obtained and is required to maintain flood
     insurance.

               (xl) Engineering Assessments. One or more engineering assessments
     or updates of a previously conducted engineering assessment were performed
     by an Independent engineering consulting firm with respect to each related
     Mortgaged Property during the 12-month period preceding the Cut-off Date,
     and the Depositor having made no independent inquiry other than to review
     the report(s) prepared in connection with such assessment(s) and or
     update(s), does not have any knowledge of any material and adverse
     engineering condition or circumstance affecting such Mortgaged Property
     that was not disclosed in such report(s); and, to the extent such
     assessments revealed deficiencies, deferred maintenance or similar
     conditions, either (A) the estimated cost has been escrowed or a letter of
     credit has been provided, (B) repairs have been made or (C) the scope of
     the deferred maintenance relative to the value of such Mortgaged Property
     was de minimis.

               (xli) Escrows. All escrow deposits and payments relating to such
     Mortgage Loan are under control of the Depositor or the servicer of such
     Mortgage Loan and all amounts required as of the date hereof under the
     related Mortgage Loan documents to be deposited by the related Mortgagor
     have been deposited. The Depositor is transferring to the Trustee all of
     its right, title and interest in and to such amounts.

               (xlii) Licenses, Permits and Authorizations. The related
     Mortgagor has represented in the related Mortgage Loan documents that, and
     to the actual knowledge of the Depositor, as of the date of origination of
     such Mortgage Loan, all material licenses, permits and authorizations then
     required for use of the related Mortgaged Property by such Mortgagor, the
     related lessee, franchisor or operator have been issued and were valid and
     in full force and effect.

               (xliii) Servicing and Collection Practices. The servicing and
     collection practices used by the Depositor and the applicable Lehman
     Mortgage Loan Seller or, to the Depositor's knowledge, any other prior
     holder of the related Mortgage Note with respect to such Mortgage Loan have
     been in all respects legal and have met customary industry standards.

               (xliv) Fee Simple. Unless such Mortgage Loan is covered by the
     representation and warranty in the immediately following paragraph (xlv),
     such Mortgage Loan is secured in whole or in material part by a fee simple
     interest.

               (xlv) Leasehold Interest Only. If such Mortgage Loan is secured
     in whole or in material part by the interest of the related Mortgagor as a
     lessee under a Ground Lease but not by the related fee interest, then:



               (A)  such Ground Lease or a memorandum thereof has been or will
                    be duly recorded and such Ground Lease permits the interest
                    of the lessee thereunder to be encumbered by the related
                    Mortgage or, if consent of the lessor thereunder is
                    required, it has been obtained prior to the Closing Date;

               (B)  upon the foreclosure of such Mortgage Loan (or acceptance of
                    a deed in lieu thereof), the Mortgagor's interest in such
                    Ground Lease is assignable to the Trustee without the
                    consent of the lessor thereunder (or, if any such consent is
                    required, it has been obtained prior to the Closing Date)
                    and, in the event that it is so assigned, is further
                    assignable by the Trustee and its successors without a need
                    to obtain the consent of such lessor (or, if any such
                    consent is required, it has been obtained prior to the
                    Closing Date or may not be unreasonably withheld);

               (C)  such Ground Lease may not be amended or modified without the
                    prior written consent of the mortgagee under such Mortgage
                    Loan and any such action without such consent is not binding
                    on such mortgagee, its successors or assigns;

               (D)  unless otherwise set forth in such Ground Lease, such Ground
                    Lease does not permit any increase in the amount of rent
                    payable by the ground lessee thereunder during the term of
                    such Mortgage Loan;

               (E)  such Ground Lease was in full force and effect as of the
                    date of origination of the related Mortgage Loan and, at the
                    Closing Date, such Ground Lease is in full force and effect;
                    to the actual knowledge of the Depositor, except for
                    payments due but not yet 30 days or more delinquent, (1)
                    there is no material default under such Ground Lease, and
                    (2) there is no event which, with the passage of time or
                    with notice and the expiration of any grace or cure period,
                    would constitute a material default under such Ground Lease;

               (F)  such Ground Lease, or an estoppel or consent letter received
                    by the mortgagee under such Mortgage Loan from the lessor,
                    requires the lessor thereunder to give notice of any default
                    by the lessee to such mortgagee; and such Ground Lease, or
                    an estoppel or consent letter received by the mortgagee
                    under such Mortgage Loan from the lessor, further provides
                    either (1) that no notice of termination given under such
                    Ground Lease is effective against such mortgagee unless a
                    copy has been delivered to the mortgagee in the manner
                    described in such Ground Lease, estoppel or consent letter
                    or (2) that upon any termination of such Ground Lease the
                    lessor will enter into a new lease with such mortgagee upon
                    such mortgagee's request;

               (G)  based upon the related policy of title insurance, the ground
                    lessee's interest in such Ground Lease is not subject to any
                    liens or encumbrances superior to, or of equal priority
                    with, the related Mortgage, other than the related ground
                    lessor's related fee interest and any Permitted
                    Encumbrances;



               (H)  the mortgagee under such Mortgage Loan is permitted a
                    reasonable opportunity to cure any curable default under
                    such Ground Lease (not less than the time provided to the
                    related lessee under such Ground Lease to cure such default)
                    before the lessor thereunder may terminate or cancel such
                    Ground Lease;

               (I)  such Ground Lease has a currently effective term (including
                    any options exercisable by the holder of the related
                    Mortgage) that extends not less than 20 years beyond the
                    Stated Maturity Date of the related Mortgage Loan;

               (J)  under the terms of such Ground Lease, any estoppel or
                    consent letter received by the mortgagee under such Mortgage
                    Loan from the lessor and the related Mortgage Loan
                    documents, taken together, any related insurance proceeds,
                    other than de minimis amounts for minor casualties, with
                    respect to the leasehold interest, or condemnation proceeds
                    will be applied either to the repair or restoration of all
                    or part of the related Mortgaged Property, with the
                    mortgagee or a trustee appointed by it having the right to
                    hold and disburse such proceeds as the repair or restoration
                    progresses (except in such cases where a provision entitling
                    another party to hold and disburse such proceeds would not
                    be viewed as commercially unreasonable by a prudent
                    commercial mortgage lender), or to the payment of the
                    outstanding principal balance of the Mortgage Loan, together
                    with any accrued interest thereon;

               (K)  such Ground Lease does not impose any restrictions on use or
                    subletting which would be viewed as commercially
                    unreasonable by a prudent commercial mortgage lender;

               (L)  upon the request of the mortgagee under such Mortgage Loan,
                    the ground lessor under such Ground Lease is required to
                    enter into a new lease upon termination of the Ground Lease
                    for any reason prior to the expiration of the term thereof,
                    including as a result of the rejection of the Ground Lease
                    in a bankruptcy of the related Mortgagor unless the
                    mortgagee under such Mortgage Loan fails to cure a default
                    of the lessee under such Ground Lease following notice
                    thereof from the lessor; and

               (M)  the terms of the related Ground Lease have not been waived,
                    modified, altered, satisfied, impaired, canceled,
                    subordinated or rescinded in any manner which materially
                    interferes with the security intended to be provided by such
                    Mortgage, except as set forth in an instrument or document
                    contained in the related Mortgage File.

               (xlvi) Fee Simple and Leasehold Interest. If such Mortgage Loan
     is secured by the interest of the related Mortgagor under a Ground Lease
     and by the related fee interest, then (A) such fee interest is subject, and
     subordinated of record, to the related Mortgage, (B) the related Mortgage
     does not by its terms provide that it will be subordinated to the lien of
     any other mortgage or other lien upon such fee interest, and (C) upon
     occurrence of a default under the terms of the related Mortgage by the
     related Mortgagor, the mortgagee under such Mortgage



     Loan has the right (subject to the limitations and exceptions set forth in
     paragraph (v) above) to foreclose upon or otherwise exercise its rights
     with respect to such fee interest.

               (xlvii) Tax Lot; Utilities. Each related Mortgaged Property
     constitutes one or more complete separate tax lots (or the related
     Mortgagor has covenanted to obtain separate tax lots and an escrow of funds
     in an amount sufficient to pay taxes resulting from a breach thereof has
     been established) or is subject to an endorsement under the related title
     insurance policy; and each related Mortgaged Property is served by a public
     or other acceptable water system, a public sewer (or, alternatively, a
     septic) system, and other customary utility facilities.

               (xlviii) Defeasance. If such Trust Mortgage Loan is a Defeasance
     Mortgage Loan, the related Mortgage Loan documents require the related
     Mortgagor to pay all reasonable costs associated with the defeasance
     thereof, and either: (A) require the prior written consent of, and
     compliance with the conditions set by, the holder of such Trust Mortgage
     Loan for defeasance or (B) require that (1) defeasance may not occur prior
     to the second anniversary of the Closing Date, (2) the Defeasance
     Collateral must be government securities within the meaning of Treasury
     regulations section 1.860G-2(a)(8)(i) and must be sufficient to make all
     scheduled payments under the related Mortgage Note when due (assuming for
     each ARD Mortgage Loan that it matures on its Anticipated Repayment Date or
     on the date when any open prepayment period set forth in the related
     Mortgage Loan documents commences) or, in the case of a partial defeasance
     that effects the release of a material portion of the related Mortgaged
     Property, to make all scheduled payments under the related Mortgage Note on
     that part of such Mortgage Loan equal to at least 110% of the allocated
     loan amount of the portion of the Mortgaged Property being released, (3) an
     independent accounting firm (which may be the Mortgagor's independent
     accounting firm) certify that the Defeasance Collateral is sufficient to
     make such payments, (4) such Mortgage Loan be assumed by a successor entity
     designated by the holder of such Mortgage Loan (or by the Mortgagor with
     the approval of such lender), and (5) counsel provide an opinion letter to
     the effect that the Trustee has a perfected security interest in such
     Defeasance Collateral prior to any other claim or interest.

               (xlix) Primary Servicing Rights. No Person has been granted or
     conveyed the right to primary service such Mortgage Loan or receive any
     consideration in connection therewith except (A) as contemplated in the
     Pooling and Servicing Agreement with respect to primary servicers that are
     to be sub-servicers of the Master Servicer, (B) as has been conveyed to the
     Master Servicer, in its capacity as a primary servicer, or (C) as has been
     terminated.

               (l) Mechanics' and Materialmen's Liens. As of origination and, to
     the Depositor's actual knowledge, as of the Closing Date, (A) the related
     Mortgaged Property is free and clear of any and all mechanics' and
     materialmen's liens that are not bonded, insured against or escrowed for,
     and (B) no rights are outstanding that under law could give rise to any
     such lien that would be prior or equal to the lien of the related Mortgage
     (unless affirmatively covered by the title insurance referred to in

                                 such authorization from the tenant.

                                 Countryside Acres Apartments. The Mortgagor has

                                 expire March 31, 2008. This master lease is
                                 fully subordinate to the Seller's Mortgage.

                                 Seller.

(viii) First Lien                Butterfield Corners, Colony South Apartments.
                                 Under the law of the State of Illinois,
                                 subsequently filed mechanic's liens can be
                                 superior to the lien of a mortgage.

                                 One New York Plaza. The Mortgaged Property is
                                 subject to condominium documents and therefore
                                 can become subject to a lien for the failure to
                                 pay common charges owed pursuant to such
                                 documents. In that event, the relevant lien
                                 would be prior to the Mortgage.

                                 215 Fremont Street. The Mortgage is subject to
                                 the following encumbrances:

                                 (i) A right of first refusal to purchase the
                                 Mortgaged Property granted to Charles Schwab &
                                 Co., Inc. (together with its successors and
                                 assigns, "Schwab"), the sole tenant of the
                                 Mortgaged Property. This right does not apply
                                 to a foreclosure or deed-in-lieu of
                                 foreclosure.

                                 (ii) An option to purchase the Mortgaged
                                 Property granted to Schwab at a price that is
                                 the lesser of (A) fair market value and (B) the
                                 price set forth in a schedule attached to the
                                 related ground lease. In the event that Schwab
                                 exercises this purchase option prior to the
                                 defeasance lockout date, the



                                 Mortgagor may prepay the Mortgage Loan with
                                 yield maintenance. The option price is always
                                 greater than the loan amount during the term of
                                 the Mortgage Loan and in the event it is not
                                 sufficient to cover any required yield
                                 maintenance or defeasance premium the price
                                 must be increased to do so.

                                 (iii) A termination right granted to Schwab in
                                 the event of certain major casualty or
                                 condemnation events. To exercise the

                                 Prairie Retail Plaza. A Phase I consultant
                                 reported that soil and groundwater at the
                                 Mortgaged Property have been impacted by
                                 petroleum hydrocarbons, benzene, and low levels
                                 of MTBE. Subsurface investigations conducted
                                 since the initial detection of soil and
                                 groundwater contamination in 1992 have
                                 indicated that the impact is attributable to a
                                 former on-site gasoline station, with a
                                 possible contribution from an adjacent site's
                                 former gasoline station. According to the Phase
                                 I consultant, the owner of the former gasoline
                                 station has been identified as the responsible
                                 party and has conducted ongoing groundwater
                                 monitoring and remedial work at the Mortgaged
                                 Property under the regulatory oversight of the
                                 local environmental authority since 1993. The
                                 remedial activity has involved removal of
                                 floating petroleum product and limited soil
                                 vapor extraction. The Phase I consultant stated
                                 that soil vapor extraction and an air sparging
                                 system would result in effective remediation of
                                 the site. According to the consultant, the
                                 implementation of a soil vapor extraction and
                                 air sparging system has been proposed, however,
                                 the responsible party is seeking participation
                                 by the owner of the adjacent site's former
                                 gasoline station prior to implementing these
                                 remedial measures. Based on the identification
                                 of a responsible party and the initiation of
                                 monitoring and remedial action, the Phase I
                                 consultant recommended that no further action
                                 by the Mortgagor is necessary.

distribution is made upon this Certificate.


                                     A-1-3



          The Certificates are limited in right of distribution to certain
collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Custodial Accounts, the Collection Account and,
if established, the REO Accounts may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such advances and expenses.

          The Certificates are issuable in fully registered form only without
coupons in minimum denominations specified in the Agreement. As provided in the
Agreement and subject to certain limitations therein set forth, the Certificates
are exchangeable for new Certificates of the same Class in authorized
denominations evidencing the same aggregate Percentage Interest, as requested by
the Holder surrendering the same.

          As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Certificates of the same
Class in authorized denominations evidencing the same aggregate Percentage
Interest will be issued to the designated transferee or transferees.

          No service charge will be imposed for any registration of transfer or
exchange of Certificates, but the Trustee or the Certificate Registrar may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any transfer or exchange of
Certificates.

          [FOR BOOK ENTRY CERTIFICATES: Notwithstanding the foregoing, for so
long as this Certificate is registered in the name of Cede & Co. or in such
other name as is requested by an authorized representative of DTC, transfers of
interests in this Certificate shall be made through the book-entry facilities of
DTC.]

          The Holder of this Certificate, by its acceptance hereof, shall be
deemed to have agreed to keep confidential any information it obtains from the
Trustee (except that such Holder may provide any such information obtained by it
to any other Person that holds or is contemplating the purchase of this
Certificate or an interest herein, provided that such other Person confirms in
writing such ownership interest or prospective ownership interest and agrees to
keep such information confidential). Notwithstanding the foregoing, each offeree
and/or holder of this Certificate (and each employee, representative, or other
agent of such offeree or holder) may disclose to any and all persons, without
limitation of any kind, the tax treatment and tax structure of the transactions
(as defined in section 1.6011-4 of the Treasury Department regulations)
associated herewith and all materials of any kind (including opinions or other
tax analyses) that are provided to the taxpayer relating to such tax treatment
and tax structure.

          Prior to due presentment of this Certificate for registration of
transfer, the Depositor, the Master Servicer, the Special Servicer, the Trustee,
the Certificate Registrar and any agents of any of them may treat the Person in
whose name this Certificate is registered as the owner hereof for all


                                     A-1-4



purposes, and none of the Depositor, the Master Servicer, the Special Servicer,
the Trustee, the Certificate Registrar or any such agent shall be affected by
notice to the contrary.

          Subject to certain terms and conditions set forth in the Agreement,
the Trust and the obligations created by the Agreement shall terminate upon
distribution (or provision for distribution) to the Certificateholders of all
amounts held by or on behalf of the Trustee and required to be distributed to
them pursuant to the Agreement following the earlier of (i) the final payment
(or any advance with respect thereto) on or other liquidation of the last
Mortgage Loan or REO Property remaining in the Trust, and (ii) the purchase by
the Depositor, Lehman Brothers Inc., the Master Servicer, the Special Servicer
or any Controlling Class Certificateholder at a price determined as provided in
the Agreement of all Mortgage Loans and any REO Properties remaining in the
Trust. The Agreement permits, but does not require, any Controlling Class
Certificateholder (with priority among such Holders being given to the Holder of
Certificates representing the greatest Percentage Interest in the Controlling
Class), the Special Servicer, the Master Servicer, the Depositor or Lehman
Brothers Inc., in that order of priority (with the Controlling Class
Certificateholder having the most senior priority) to purchase from the Trust
all Mortgage Loans and any REO Properties remaining therein. The exercise of
such right will effect early retirement of the Certificates; however, such right
to purchase is subject to the aggregate Stated Principal Balance of the Mortgage
Pool at the time of purchase being less than 1.0% of the initial aggregate
Certificate Principal Balance of all of the Principal Balance Certificates.

          The Agreement permits, with certain exceptions therein provided, the
amendment thereof, and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and any Fiscal
Agent thereunder and the rights of the Certificateholders thereunder, at any
time by the Depositor, the Master Servicer, the Special Servicer, the Trustee
and any Fiscal Agent with the consent of the Holders of Certificates entitled to
at least 66-2/3% of the Voting Rights allocated to the affected Classes. Any
such consent by the Holder of this Certificate shall be conclusive and binding
on such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain circumstances,
including any amendment necessary to maintain the status of any REMIC Pool as a
REMIC, without the consent of the Holders of any of the Certificates.

          Unless the certificate of authentication hereon has been executed by
the Authenticating Agent, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

          The registered Holder hereof, by its acceptance hereof, agrees that it
will look solely to the Trust (to the extent of its rights therein) for
distributions hereunder.

          This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, without applying any conflicts of law principles of such state
(other than the provisions of Section 5-1401 of the New York General Obligations
Law), and the obligations, rights and remedies of the Holder hereof shall be
determined in accordance with such laws.


                                     A-1-5



          IN WITNESS WHEREOF, the Certificate Registrar has caused this
Certificate to be duly executed.

                                      A-2-3



          The Certificates are limited in right of distribution to certain
collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Custodial Accounts, the Collection Account and,
if established, the REO Accounts may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such advances and expenses.

          The Certificates are issuable in fully registered form only without
coupons in minimum denominations specified in the Agreement. As provided in the
Agreement and subject to certain limitations therein set forth, the Certificates
are exchangeable for new Certificates of the same Class in authorized
denominations evidencing the same aggregate Percentage Interest, as requested by
the Holder surrendering the same.

          As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Certificates of the same
Class in authorized denominations evidencing the same aggregate Percentage
Interest will be issued to the designated transferee or transferees.

          No direct or indirect transfer, sale, pledge, hypothecation or other
disposition (each, a "Transfer") of this Certificate or any interest herein
shall be made unless that Transfer is exempt from the registration and/or
qualification requirements of the Securities Act and any applicable state
securities laws, or is otherwise made in accordance with the Securities Act and
such state securities laws.

          If this Certificate constitutes a Definitive Certificate and a
Transfer hereof is to be made without registration under the Securities Act
(other than in connection with the initial issuance of the Certificates or a
Transfer of this Certificate by the Depositor, Lehman Brothers Inc. or any of
their respective Affiliates or, if this Certificate is a Global Certificate, a
Transfer of this Certificate to a successor Depository or to the applicable
Certificate Owner in accordance with Section 5.03 of the Agreement), then the
Certificate Registrar shall refuse to register such Transfer unless it receives
(and, upon receipt, may conclusively rely upon) either: (i) a certificate from
the Certificateholder desiring to effect such Transfer substantially in the form
attached as Exhibit F-1 to the Agreement and a certificate from such
Certificateholder's prospective Transferee substantially in the form attached
either as Exhibit F-2A to the Agreement or as Exhibit F-2B to the Agreement; or
(ii) an Opinion of Counsel satisfactory to the Trustee to the effect that such
Transferee is an Institutional Accredited Investor or a Qualified Institutional
Buyer and such Transfer may be made without registration under the Securities
Act (which Opinion of Counsel shall not be an expense of the Trust Fund or of
the Depositor, the Master Servicer, the Special Servicer, the Trustee, any
Fiscal Agent or the Certificate Registrar in their respective capacities as
such), together with the written certification(s) as to the facts surrounding
such Transfer from the Certificateholder desiring to effect such Transfer and/or
such Certificateholder's prospective Transferee on which such Opinion of Counsel
is based. If any Transferee of this Certificate does not, in connection with the
subject Transfer, deliver to the Certificate Registrar one of the certifications
described in clause (i) of the preceding sentence or the Opinion of Counsel
described in clause (ii) of the preceding sentence, then such Transferee shall
be deemed to have represented and warranted that all the


                                      A-2-4



certifications set forth in either Exhibit F-2A or Exhibit F-2B attached to the
Agreement are, with respect to the subject Transfer, true and correct.
Definitive Non-Registered Certificates may only be held by Qualified
Institutional Buyers and Institutional Accredited Investors.

          No beneficial interest in a Rule 144A Global Certificate for any Class
of Book-Entry Non-Registered Certificates may be held by any Person that is not
a Qualified Institutional Buyer. If this Certificate constitutes a Rule 144A
Global Certificate and a Transfer of any interest herein is to be made without
registration under the Securities Act (other than in connection with the initial
issuance of the Certificates or a Transfer of any interest herein by the
Depositor, Lehman Brothers Inc. or any of their respective Affiliates), then the
Certificate Owner desiring to effect such Transfer shall be required to obtain
either (i) a certificate from such Certificate Owner's prospective Transferee
substantially in the form attached as Exhibit F-2C to the Agreement, or (ii) an
Opinion of Counsel to the effect that such Transferee is a Qualified
Institutional Buyer and such Transfer may be made without registration under the
Securities Act. If this Certificate constitutes a Rule 144A Global Certificate
and any Transferee of an interest herein does not, in connection with the
subject Transfer, deliver to the Transferor the Opinion of Counsel or the
certification described in the preceding sentence, then such Transferee shall be
deemed to have represented and warranted that all the certifications set forth
in Exhibit F-2C attached to the Agreement are, with respect to the subject
Transfer, true and correct.

          Notwithstanding the preceding paragraph, any interest in the Rule 144A
Global Certificate for a Class of Book-Entry Non-Registered Certificates may be
transferred to any Non-United States Securities Person who takes delivery in the
form of a beneficial interest in the Regulation S Global Certificate for such
Class of Certificates, provided that the Certificate Owner desiring to effect
such Transfer (i) complies with the requirements for Transfers of interests in
such Regulation S Global Certificate set forth in the following paragraph and
(ii) delivers or causes to be delivered to the Certificate Registrar and the
Trustee (A) a certificate from such Certificate Owner confirming its ownership
of the beneficial interests in the subject Class of Book-Entry Non-Registered
Certificates to be transferred, (B) a copy of the certificate to be obtained by
such Certificate Owner from its prospective Transferee in accordance with the
second sentence of the following paragraph and (C) such written orders and
instructions as are required under the applicable procedures of the Depository,
Clearstream and Euroclear to direct the Trustee, as transfer agent for the
Depository, to approve the debit of the account of a Depository Participant by a
denomination of interests in such Rule 144A Global Certificate, and approve the
credit of the account of a Depository Participant by a denomination of interests
in such Regulation S Global Certificate, that is equal to the denomination of
beneficial interests in the subject Class of Book-Entry Non-Registered
Certificates to be transferred. Upon delivery to the Certificate Registrar and
the Trustee of such certifications and such orders and instructions, the
Trustee, subject to and in accordance with the applicable procedures of the
Depository, shall reduce the denomination of the Rule 144A Global Certificate in
respect of the subject Class of Book-Entry Non-Registered Certificates, and
increase the denomination of the Regulation S Global Certificate for such Class
of Certificates, by the denomination of the beneficial interest in such Class of
Certificates specified in such orders and instructions.

          No beneficial interest in the Regulation S Global Certificate for any
Class of Book-Entry Non-Registered Certificates may be held by a United States
Securities Person. Any Certificate Owner desiring to effect any Transfer of an
interest in the Regulation S Global Certificate for any Class of Book-Entry
Non-Registered Certificates shall be required to obtain from such Certificate
Owner's prospective Transferee a certificate substantially in the form set forth
in Exhibit F-2D to the Agreement


                                      A-2-5



to the effect that such Transferee is not a United States Securities Person. If
any Transferee of an interest in the Regulation S Global Certificate for any
Class of Book-Entry Non-Registered Certificates does not, in connection with the
subject Transfer, deliver to the Transferor the certification described in the
preceding sentence, then such Transferee shall be deemed to have represented and
warranted that all the certifications set forth in Exhibit F-2D to the Agreement
are, with respect to the subject Transfer, true and correct.

          Notwithstanding the preceding paragraph, any interest in the
Regulation S Global Certificate for a Class of Book-Entry Non-Registered
Certificates may be transferred to any Qualified Institutional Buyer that takes
delivery in the form of a beneficial interest in the Rule 144A Global
Certificate for such Class of Certificates, provided that the Certificate Owner
desiring to effect such transfer (i) complies with the requirements for
Transfers of interests in such Rule 144A Global Certificate set forth in the
third paragraph above this paragraph and (ii) delivers or causes to be delivered
to the Certificate Registrar and the Trustee (A) a certificate from such
Certificate Owner confirming its ownership of the beneficial interests in the
subject Class of Book-Entry Non-Registered Certificates to be transferred, (B) a
copy of the certificate or Opinion of Counsel to be obtained by such Certificate
Owner from its prospective Transferee in accordance with the second sentence of
the third paragraph above this paragraph and (C) such written orders and
instructions as are required under the applicable procedures of the Depository,
Clearstream and Euroclear to direct the Trustee to debit the account of a
Depository Participant by a denomination of interests in such Regulation S
Global Certificate, and credit the account of a Depository Participant by a
denomination of interests in such Rule 144A Global Certificate, that is equal to
the denomination of beneficial interests in the subject Class of Book-Entry
Non-Registered Certificates to be transferred. Upon delivery to the Certificate
Registrar and the Trustee of such certification(s) and/or Opinion of Counsel and
such orders and instructions, the Trustee, subject to and in accordance with the
applicable procedures of the Depository, shall reduce the denomination of the
Regulation S Global Certificate in respect of the subject Class of Book-Entry
Non-Registered Certificates, and increase the denomination of the Rule 144A
Global Certificate for such Class of Certificates, by the denomination of the
beneficial interest in such Class of Certificates specified in such orders and
instructions.

          Also notwithstanding the foregoing, any interest in a Global
Certificate with respect to any Class of Book-Entry Non-Registered Certificates
may be transferred by any Certificate Owner holding such interest to any
Institutional Accredited Investor (other than a Qualified Institutional Buyer)
that takes delivery in the form of a Definitive Certificate of the same Class as
such Global Certificate upon delivery to the Certificate Registrar and the
Trustee of (i) such certifications and/or opinions as are contemplated by the
fifth paragraph above this paragraph and (ii) such written orders and
instructions as are required under the applicable procedures of the Depository
to direct the Trustee to debit the account of a Depository Participant by the
denomination of the transferred interests in such Global Certificate. Upon
delivery to the Certificate Registrar and the Trustee of the certifications

          None of the Depositor, the Trustee or the Certificate Registrar is
obligated to register or qualify the Class of Certificates to which this
Certificate belongs, under the Securities Act or any other securities law or to
take any action not otherwise required under the Agreement to permit the
Transfer of this Certificate or any interest herein without such registration or
qualification. Any Certificateholder or Certificate Owner desiring to effect a
Transfer of this Certificate or any interest herein shall, and does hereby agree
to, indemnify the Depositor, Lehman Brothers Inc., UBS Securities LLC, the
Trustee, any Fiscal Agent, the Master Servicer, the Special Servicer, the
Certificate Registrar and their respective Affiliates against any liability that
may result if such Transfer is not exempt from the registration and/or
qualification requirements of the Securities Act and any applicable state
securities laws or is not made in accordance with such federal and state laws.

          No Transfer of this Certificate or any interest herein shall be made
to (A) any employee benefit plan or other retirement arrangement, including
individual retirement accounts and annuities, Keogh plans and collective
investment funds and separate accounts in which such plans, accounts or
arrangements are invested, including insurance company general accounts, that is
subject to ERISA or the Code (each, a "Plan"), or (B) any Person who is directly
or indirectly purchasing this Certificate or such interest herein on behalf of,
as named fiduciary of, as trustee of, or with assets of a Plan, if the purchase
and holding of this Certificate or such interest herein by the prospective
Transferee would result in a violation of Section 406 or 407 of ERISA or Section
4975 of the Code or would result in the imposition of an excise tax under
Section 4975 of the Code. Except in connection with the initial issuance of the
Certificates or any Transfer of this Certificate or any interest herein by the
Depositor, Lehman Brothers Inc. or any of their respective Affiliates or, if
this Certificate constitutes a Global Certificate, any Transfer of this
Certificate to a successor Depository or to the applicable Certificate Owner in
accordance with Section 5.03 of the Agreement, the Certificate Registrar shall
refuse to register the Transfer of this Certificate unless it has received from
the prospective Transferee, and, if this Certificate constitutes a Global
Certificate, any Certificate Owner transferring an interest herein shall be
required to obtain from its prospective Transferee one of the following: (i) a
certification to the effect that such prospective Transferee is not a Plan and
is not directly or indirectly purchasing this Certificate or such interest
herein on behalf of, as named fiduciary of, as trustee of, or with assets of a
Plan; or (ii) a certification to the effect that the purchase and holding of
this Certificate or such interest herein by such prospective Transferee is
exempt from the prohibited transaction provisions of Sections 406(a) and (b) and
407 of ERISA and the excise taxes imposed on such prohibited transactions by
Sections 4975(a) and (b) of the Code, by reason of Sections I and III of
Prohibited Transaction Class Exemption 95-60; or (iii) if this Certificate is
rated in one of the four highest generic rating categories by either Rating
Agency, and this Certificate or an interest herein is being acquired by or on
behalf of a Plan in reliance on any of Prohibited Transaction Exemption 91-14, a
certification to the effect that such Plan (X) is an accredited investor as
defined in Rule 501(a)(1) of Regulation D of the Securities Act, (Y) is not
sponsored (within the meaning of Section 3(16)(B) of ERISA) by the Trustee, the
Depositor, any Mortgage Loan Seller, the Master Servicer, the Special Servicer,
any Sub-Servicer, any Person responsible for servicing any Outside Serviced
Trust Mortgage Loan or administering an Outside Administered REO Property, any
Exemption-Favored Party or any Mortgagor with respect to Mortgage Loans
constituting more than 5% of the aggregate unamortized principal balance of all
the Mortgage Loans determined as of the Closing Date, or by any Affiliate of
such Person, and (Z) agrees that it will obtain from each of its Transferees
that are Plans a written representation that such Transferee, if a Plan,
satisfies the requirements of the immediately preceding clauses (X) and (Y),
together with a written agreement that such Transferee will obtain from each of
its Transferees that are Plans a similar written representation regarding
satisfaction of the requirements of the immediately preceding clauses (X) and
(Y); or (iv) a certification of facts and


                                      A-2-7



an Opinion of Counsel which otherwise establish to the reasonable satisfaction
of the Trustee or such Certificate Owner, as the case may be, that such Transfer
will not result in a violation of Section 406 or 407 of ERISA or Section 4975 of
the Code or result in the imposition of an excise tax under Section 4975 of the
Code. If any Transferee of this Certificate or any interest herein does not, in
connection with the subject Transfer, deliver to the Certificate Registrar (if
this Certificate constitutes a Definitive Certificate) or the Transferor (if
this Certificate constitutes a Global Certificate) a certification and/or
Opinion of Counsel as required by the preceding sentence, then such Transferee
shall be deemed to have represented and warranted that either: (i) such
Transferee is not a Plan and is not directly or indirectly purchasing this
Certificate or any interest herein on behalf of, as named fiduciary of, as
trustee of, or with assets of a Plan; or (ii) the purchase and holding of this
Certificate or such interest herein by such Transferee is exempt from the
prohibited transaction provisions of Sections 406(a) and (b) and 407 of ERISA
and the excise taxes imposed on such prohibited transactions by Sections 4975(a)
and (b) of the Code.

          No service charge will be imposed for any registration of transfer or
exchange of Certificates, but the Trustee or the Certificate Registrar may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any transfer or exchange of
Certificates.

          [FOR BOOK ENTRY CERTIFICATES: Notwithstanding the foregoing, for so
long as this Certificate is registered in the name of Cede & Co. or in such
other name as is requested by an authorized representative of DTC, transfers of
interests in this Certificate shall be made through the book-entry facilities of
DTC.]

          The Holder of this Certificate, by its acceptance hereof, shall be
deemed to have agreed to keep confidential any information it obtains from the
Trustee (except that such Holder may provide any such information obtained by it
to any other Person that holds or is contemplating the purchase of this
Certificate or an interest herein, provided that such other Person confirms in
writing such ownership interest or prospective ownership interest and agrees to
keep such information confidential). Notwithstanding the foregoing, each offeree
and/or holder of this Certificate (and each employee, representative, or other
agent of such offeree or holder) may disclose to any and all persons, without
limitation of any kind, the tax treatment and tax structure of the transactions
(as defined in section 1.6011-4 of the Treasury Department regulations)
associated herewith and all materials of any kind (including opinions or other
tax analyses) that are provided to the taxpayer relating to such tax treatment
and tax structure.

          Prior to due presentment of this Certificate for registration of
transfer, the Depositor, the Master Servicer, the Special Servicer, the Trustee,
the Certificate Registrar and any agents of any of them may treat the Person in
whose name this Certificate is registered as the owner hereof for all purposes,
and none of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Certificate Registrar or any such agent shall be affected by notice
to the contrary.

          Subject to certain terms and conditions set forth in the Agreement,
the Trust and the obligations created by the Agreement shall terminate upon
distribution (or provision for distribution) to the Certificateholders of all
amounts held by or on behalf of the Trustee and required to be distributed to
them pursuant to the Agreement following the earlier of (i) the final payment
(or any advance with respect thereto) on or other liquidation of the last
Mortgage Loan or REO Property remaining in the


                                      A-2-8



Trust, and (ii) the purchase by the Depositor, Lehman Brothers Inc., the Master
Servicer, the Special Servicer or any Controlling Class Certificateholder at a
price determined as provided in the Agreement of all Mortgage Loans and any REO
Properties remaining in the Trust. The Agreement permits, but does not require,
any Controlling Class Certificateholder (with priority among such Holders being
given to the Holder of Certificates representing the greatest Percentage
Interest in the Controlling Class), the Special Servicer, the Master Servicer,
the Depositor or Lehman Brothers Inc., in that order of priority (with the
Controlling Class Certificateholder having the most senior priority) to purchase
from the Trust all Mortgage Loans and any REO Properties remaining therein. The
exercise of such right will effect early retirement of the Certificates;
however, such right to purchase is subject to the aggregate Stated Principal
Balance of the Mortgage Pool at the time of purchase being less than 1.0% of the
initial aggregate Certificate Principal Balance of all of the Principal Balance
Certificates.

          The Agreement permits, with certain exceptions therein provided, the
amendment thereof, and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and any Fiscal
Agent thereunder and the rights of the Certificateholders thereunder, at any
time by the Depositor, the Master Servicer, the Special Servicer, the Trustee
and any Fiscal Agent with the consent of the Holders of Certificates entitled to
at least 66-2/3% of the Voting Rights allocated to the affected Classes. Any
such consent by the Holder of this Certificate shall be conclusive and binding
on such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain circumstances,
including any amendment necessary to maintain the status of any REMIC Pool as a
REMIC, without the consent of the Holders of any of the Certificates.

          Unless the certificate of authentication hereon has been executed by
the Authenticating Agent, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

          The registered Holder hereof, by its acceptance hereof, agrees that it
will look solely to the Trust (to the extent of its rights therein) for
distributions hereunder.

          This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, without applying any conflicts of law principles of such state
(other than the provisions of Section 5-1401 of the New York General Obligations
Law), and the obligations, rights and remedies of the Holder hereof shall be
determined in accordance with such laws.


                                      A-2-9



          IN WITNESS WHEREOF, the Certificate Registrar has caused this
Certificate to be duly executed.

THE CLASS OF CERTIFICATES TO WHICH THIS CERTIFICATE BELONGS IS SUBORDINATE TO
ONE OR MORE OTHER CLASSES OF CERTIFICATES OF THE SAME SERIES, AS AND TO THE
EXTENT PROVIDED IN THE POOLING AND SERVICING AGREEMENT REFERRED TO HEREIN.

SOLELY FOR U.S. FEDERAL INCOME TAX PURPOSES, THIS CERTIFICATE IS A "REGULAR
INTEREST" IN A "REAL ESTATE MORTGAGE INVESTMENT CONDUIT" (A "REMIC") AS THOSE
TERMS ARE DEFINED, RESPECTIVELY, IN SECTIONS 860G AND 860D OF THE CODE.

THE OUTSTANDING CERTIFICATE PRINCIPAL BALANCE HEREOF AT ANY TIME MAY BE LESS
THAN THE AMOUNT SHOWN ABOVE.

          This certifies that Cede & Co. is the registered owner of the
Percentage Interest evidenced by this Certificate (obtained by dividing the
principal balance of this Certificate (its


                                     A-3-2



"Certificate Principal Balance") as of the Closing Date by the aggregate
principal balance of all the Certificates of the same Class as this Certificate
(their "Class Principal Balance") as of the Closing Date) in that certain
beneficial ownership interest in the Trust evidenced by all the Certificates of
the same Class as this Certificate. The Trust was created and the Certificates
were issued pursuant to a Pooling and Servicing Agreement, dated as specified
above (the "Agreement"), between Structured Asset Securities Corporation II, as
depositor (the "Depositor", which term includes any successor entity under the
Agreement), Wachovia Bank, National Association, as master servicer (the "Master
Servicer", which term includes any successor entity under the Agreement), LNR
Partners, Inc., as special servicer (the "Special Servicer", which term includes
any successor entity under the Agreement), and LaSalle Bank National
Association, as trustee (the "Trustee", which term includes any successor entity
under the Agreement), a summary of certain of the pertinent provisions of which
is set forth hereafter. To the extent not defined herein, the capitalized terms
used herein have the respective meanings assigned in the Agreement. This
Certificate is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which Agreement the Holder of this Certificate
by virtue of the acceptance hereof assents and by which such Holder is bound. In
the event of any conflict between any provision of this Certificate and any
provision of the Agreement, such provision of this Certificate shall be
superseded to the extent of such inconsistency.

          Pursuant to the terms of the Agreement, distributions will be made on
the 4th Business Day following the 11th calendar day of each month (or, if such
11th calendar day is not a Business Day, then the 5th Business Day following
such 11th calendar day) (each, a "Distribution Date"), commencing on the first
Distribution Date specified above, to the Person in whose name this Certificate
is registered at the close of business on the last Business Day of the month
immediately preceding the month of such distribution (the "Record Date"), in an
amount equal to the product of the Percentage Interest evidenced by this
Certificate and the amount required to be distributed pursuant to the Agreement
on the applicable Distribution Date in respect of the Class of Certificates to
which this Certificate belongs, provided that, in the case of the initial
Distribution Date, the Record Date shall be the Closing Date. All distributions
made under the Agreement in respect of this Certificate will be made by the
Trustee by wire transfer in immediately available funds to the account of the
Person entitled thereto at a bank or other entity having appropriate facilities
therefor, if such Certificateholder shall have provided the Trustee with written
wiring instructions generally no less than five (5) Business Days prior to (or,
in the case of the first such distribution, no later than) the Record Date for
such distribution (which wiring instructions may be in the form of a standing
order applicable to all subsequent distributions as well), or otherwise by check
mailed to the address of such Certificateholder appearing in the Certificate
Register. Notwithstanding the above, the final distribution in respect of this
Certificate (determined without regard to any possible future reimbursement of
any related Loss Reimbursement Amount) will be made after due notice by the
Trustee of the pendency of such distribution and only upon presentation and
surrender of this Certificate at the offices of the Certificate Registrar
appointed as provided in the Agreement or such other location as may be
specified in such notice. Also notwithstanding the foregoing, any distribution
that may be made with respect to this Certificate in reimbursement of any
related Loss Reimbursement Amount, which reimbursement is to occur after the
date on which this Certificate is surrendered as contemplated by the preceding
sentence, will be made by check mailed to the address of the Holder that
surrenders this Certificate as such address last appeared in the Certificate
Register or to any such other address of which the Trustee is subsequently
notified in writing.

          Any distribution to the Holder of this Certificate in reduction of the
Certificate Principal Balance hereof is binding on such Holder and all future
Holders of this Certificate and any Certificate


                                     A-3-3



issued upon the transfer hereof or in exchange herefor or in lieu hereof whether
or not notation of such distribution is made upon this Certificate.

          The Certificates are limited in right of distribution to certain
collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Custodial Accounts, the Collection Account and,
if established, the REO Accounts may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such advances and expenses.

          The Certificates are issuable in fully registered form only without
coupons in minimum denominations specified in the Agreement. As provided in the
Agreement and subject to certain limitations therein set forth, the Certificates
are exchangeable for new Certificates of the same Class in authorized
denominations evidencing the same aggregate Percentage Interest, as requested by
the Holder surrendering the same.

          As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Certificates of the same
Class in authorized denominations evidencing the same aggregate Percentage
Interest will be issued to the designated transferee or transferees.

          No service charge will be imposed for any registration of transfer or
exchange of Certificates, but the Trustee or the Certificate Registrar may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any transfer or exchange of
Certificates.

          [FOR BOOK ENTRY CERTIFICATES: Notwithstanding the foregoing, for so
long as this Certificate is registered in the name of Cede & Co. or in such
other name as is requested by an authorized representative of DTC, transfers of
interests in this Certificate shall be made through the book-entry facilities of
DTC.]

          The Holder of this Certificate, by its acceptance hereof, shall be
deemed to have agreed to keep confidential any information it obtains from the
Trustee (except that such Holder may provide any such information obtained by it
to any other Person that holds or is contemplating the purchase of this
Certificate or an interest herein, provided that such other Person confirms in
writing such ownership interest or prospective ownership interest and agrees to
keep such information confidential). Notwithstanding the foregoing, each offeree
and/or holder of this Certificate (and each employee, representative, or other
agent of such offeree or holder) may disclose to any and all persons, without
limitation of any kind, the tax treatment and tax structure of the transactions
(as defined in section 1.6011-4 of the Treasury Department regulations)
associated herewith and all materials of any kind (including opinions or other
tax analyses) that are provided to the taxpayer relating to such tax treatment
and tax structure.


                                     A-3-4



          Prior to due presentment of this Certificate for registration of
transfer, the Depositor, the Master Servicer, the Special Servicer, the Trustee,
the Certificate Registrar and any agents of any of them may treat the Person in
whose name this Certificate is registered as the owner hereof for all purposes,
and none of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Certificate Registrar or any such agent shall be affected by notice
to the contrary.

          Subject to certain terms and conditions set forth in the Agreement,
the Trust and the obligations created by the Agreement shall terminate upon
distribution (or provision for distribution) to the Certificateholders of all
amounts held by or on behalf of the Trustee and required to be distributed to
them pursuant to the Agreement following the earlier of (i) the final payment
(or any advance with respect thereto) on or other liquidation of the last
Mortgage Loan or REO Property remaining in the Trust, and (ii) the purchase by
the Depositor, Lehman Brothers Inc., the Master Servicer, the Special Servicer
or any Controlling Class Certificateholder at a price determined as provided in
the Agreement of all Mortgage Loans and any REO Properties remaining in the
Trust. The Agreement permits, but does not require, any Controlling Class
Certificateholder (with priority among such Holders being given to the Holder of
Certificates representing the greatest Percentage Interest in the Controlling
Class), the Special Servicer, the Master Servicer, the Depositor or Lehman
Brothers Inc., in that order of priority (with the Controlling Class
Certificateholder having the most senior priority) to purchase from the Trust
all Mortgage Loans and any REO Properties remaining therein. The exercise of
such right will effect early retirement of the Certificates; however, such right
to purchase is subject to the aggregate Stated Principal Balance of the Mortgage
Pool at the time of purchase being less than 1.0% of the initial aggregate
Certificate Principal Balance of all of the Principal Balance Certificates.

          The Agreement permits, with certain exceptions therein provided, the
amendment thereof, and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and any Fiscal
Agent thereunder and the rights of the Certificateholders thereunder, at any
time by the Depositor, the Master Servicer, the Special Servicer, the Trustee
and any Fiscal Agent with the consent of the Holders of Certificates entitled to
at least 66-2/3% of the Voting Rights allocated to the affected Classes. Any
such consent by the Holder of this Certificate shall be conclusive and binding

Agreement the Holder of this Certificate by virtue of the acceptance hereof

provision of this Certificate shall be superseded to the extent of such
inconsistency.

          Pursuant to the terms of the Agreement, distributions will be made on

Distribution Date specified above, to the Person in whose name this Certificate

therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices of the Certificate Registrar, duly endorsed by, or

qualification requirements of the Securities Act and any applicable state
securities laws, or is otherwise made in accordance with the Securities Act and
such state securities laws.

          If this Certificate constitutes a Definitive Certificate and a
Transfer hereof is to be made without registration under the Securities Act
(other than in connection with the initial issuance of the Certificates or a
Transfer of this Certificate by the Depositor, Lehman Brothers Inc. or any of
their respective Affiliates or, if this Certificate is a Global Certificate, a
Transfer of this Certificate to a successor Depository or to the applicable
Certificate Owner in accordance with Section 5.03 of the Agreement), then the
Certificate Registrar shall refuse to register such Transfer unless it receives
(and, upon receipt, may conclusively rely upon) either: (i) a certificate from
the Certificateholder desiring to effect such Transfer substantially in the form
attached as Exhibit F-1 to the Agreement and a certificate from such
Certificateholder's prospective Transferee substantially in the form attached
either as Exhibit F-2A to the Agreement or as Exhibit F-2B to the Agreement; or
(ii) an Opinion of Counsel satisfactory


                                     A-4-4

without registration under the Securities Act (which Opinion of Counsel shall

the Special Servicer, the Trustee, any Fiscal Agent or the Certificate Registrar
in their respective capacities as such), together with the written
certification(s) as to the facts surrounding such Transfer from the
Certificateholder desiring to effect such Transfer and/or such
Certificateholder's prospective Transferee on which such Opinion of Counsel is
based. If any Transferee of this Certificate does not, in connection with the
subject Transfer, deliver to the Certificate Registrar one of the certifications
described in clause (i) of the preceding sentence or the Opinion of Counsel
described in clause (ii) of the preceding sentence, then such Transferee shall
be deemed to have represented and warranted that all the certifications set
forth in either Exhibit F-2A or Exhibit F-2B attached to the Agreement are, with
respect to the subject Transfer, true and correct. Definitive Non-Registered
Certificates may only be held by Qualified Institutional Buyers and
Institutional Accredited Investors.

          No beneficial interest in a Rule 144A Global Certificate for any Class
of Book-Entry Non-Registered Certificates may be held by any Person that is not
a Qualified Institutional Buyer. If this Certificate constitutes a Rule 144A
Global Certificate and a Transfer of any interest herein is to be made without
registration under the Securities Act (other than in connection with the initial
issuance of the Certificates or a Transfer of any interest herein by the
Depositor, Lehman Brothers Inc. or any of their respective Affiliates), then the
Certificate Owner desiring to effect such Transfer shall be required to obtain
either (i) a certificate from such Certificate Owner's prospective Transferee
substantially in the form attached as Exhibit F-2C to the Agreement, or (ii) an
Opinion of Counsel to the effect that such Transferee is a Qualified

Securities Act. If this Certificate constitutes a Rule 144A Global Certificate
and any Transferee of an interest herein does not, in connection with the

certification described in the preceding sentence, then such Transferee shall be
deemed to have represented and warranted that all the certifications set forth
in Exhibit F-2C attached to the Agreement are, with respect to the subject
Transfer, true and correct. Furthermore, if this Certificate constitutes a Rule
144A Global Certificate for the Class T Certificates and a Transfer of any
interest herein is to be made without registration under the Securities Act, any
Certificate Owner desiring to effect a transfer of this Certificate or any
interest herein may not sell or otherwise transfer this Certificate or any
interest herein unless it has provided the Depositor with prior written notice
of such transfer (together with a copy of the certificate (executed by the
proposed transferee) or Opinion of Counsel referred to above in this paragraph);
such notice to be delivered to Structured Asset Securities Corporation II, 745
Seventh Avenue, New York, New York 10019, Attention: Scott Lechner--LB-UBS

          Notwithstanding the preceding paragraph, any interest in the Rule 144A
Global Certificate for a Class of Book-Entry Non-Registered Certificates may be
transferred to any Non-United States Securities Person who takes delivery in the
form of a beneficial interest in the Regulation S Global Certificate for such
Class of Certificates, provided that the Certificate Owner desiring to effect
such Transfer (i) complies with the requirements for Transfers of interests in
such Regulation S Global Certificate set forth in the following paragraph and
(ii) delivers or causes to be delivered to the Certificate Registrar and the
Trustee (A) a certificate from such Certificate Owner confirming its ownership
of the beneficial interests in the subject Class of Book-Entry Non-Registered
Certificates to be transferred, (B) a copy of the certificate to be obtained by
such Certificate Owner from its prospective Transferee in accordance with the
second sentence of the following paragraph and (C) such written


                                     A-4-5



orders and instructions as are required under the applicable procedures of the
Depository, Clearstream and Euroclear to direct the Trustee, as transfer agent
for the Depository, to approve the debit of the account of a Depository
Participant by a denomination of interests in such Rule 144A Global Certificate,
and approve the credit of the account of a Depository Participant by a
denomination of interests in such Regulation S Global Certificate, that is equal
to the denomination of beneficial interests in the subject Class of Book-Entry
Non-Registered Certificates to be transferred. Upon delivery to the Certificate
Registrar and the Trustee of such certifications and such orders and
instructions, the Trustee, subject to and in accordance with the applicable
procedures of the Depository, shall reduce the denomination of the Rule 144A
Global Certificate in respect of the subject Class of Book-Entry Non-Registered
Certificates, and increase the denomination of the Regulation S Global
Certificate for such Class of Certificates, by the denomination of the
beneficial interest in such Class of Certificates specified in such orders and
instructions.

          No beneficial interest in the Regulation S Global Certificate for any
Class of Book-Entry Non-Registered Certificates may be held by a United States
Securities Person. Any Certificate Owner desiring to effect any Transfer of an
interest in the Regulation S Global Certificate for any Class of Book-Entry
Non-Registered Certificates shall be required to obtain from such Certificate
Owner's prospective Transferee a certificate substantially in the form set forth
in Exhibit F-2D to the Agreement to the effect that such Transferee is not a
United States Securities Person. If any Transferee of an interest in the
Regulation S Global Certificate for any Class of Book-Entry Non-Registered
Certificates does not, in connection with the subject Transfer, deliver to the
Transferor the certification described in the preceding sentence, then such
Transferee shall be deemed to have represented and warranted that all the
certifications set forth in Exhibit F-2D to the Agreement are, with respect to
the subject Transfer, true and correct.

          Notwithstanding the preceding paragraph, any interest in the
Regulation S Global Certificate for a Class of Book-Entry Non-Registered
Certificates may be transferred to any Qualified Institutional Buyer that takes
delivery in the form of a beneficial interest in the Rule 144A Global
Certificate for such Class of Certificates, provided that the Certificate Owner
desiring to effect such transfer (i) complies with the requirements for
Transfers of interests in such Rule 144A Global Certificate set forth in the
third paragraph above this paragraph and (ii) delivers or causes to be delivered
to the Certificate Registrar and the Trustee (A) a certificate from such
Certificate Owner confirming its ownership of the beneficial interests in the
subject Class of Book-Entry Non-Registered Certificates to be transferred, (B) a
copy of the certificate or Opinion of Counsel to be obtained by such Certificate
Owner from its prospective Transferee in accordance with the second sentence of
the third paragraph above this paragraph and (C) such written orders and
instructions as are required under the applicable procedures of the Depository,
Clearstream and Euroclear to direct the Trustee to debit the account of a
Depository Participant by a denomination of interests in such Regulation S
Global Certificate, and credit the account of a Depository Participant by a
denomination of interests in such Rule 144A Global Certificate, that is equal to
the denomination of beneficial interests in the subject Class of Book-Entry
Non-Registered Certificates to be transferred. Upon delivery to the Certificate
Registrar and the Trustee of such certification(s) and/or Opinion of Counsel and
such orders and instructions, the Trustee, subject to and in accordance with the
applicable procedures of the Depository, shall reduce the denomination of the
Regulation S Global Certificate in respect of the subject Class of Book-Entry
Non-Registered Certificates, and increase the denomination of the Rule 144A
Global Certificate for such Class of Certificates, by the denomination of the
beneficial interest in such Class of Certificates specified in such orders and
instructions.


                                     A-4-6



          Also notwithstanding the foregoing, any interest in a Global
Certificate with respect to any Class of Book-Entry Non-Registered Certificates
may be transferred by any Certificate Owner holding such interest to any
Institutional Accredited Investor (other than a Qualified Institutional Buyer)
that takes delivery in the form of a Definitive Certificate of the same Class as
such Global Certificate upon delivery to the Certificate Registrar and the
Trustee of (i) such certifications and/or opinions as are contemplated by the
fifth paragraph above this paragraph and (ii) such written orders and
instructions as are required under the applicable procedures of the Depository
to direct the Trustee to debit the account of a Depository Participant by the
denomination of the transferred interests in such Global Certificate. Upon
delivery to the Certificate Registrar and the Trustee of the certifications
and/or opinions contemplated by the fifth paragraph above this paragraph, the
Trustee, subject to and in accordance with the applicable procedures of the
Depository, shall reduce the denomination of the subject Global Certificate by
the denomination of the transferred interests in such Global Certificate, and
shall cause a Definitive Certificate of the same Class as such Global
Certificate, and in a denomination equal to the reduction in the denomination of
such Global Certificate, to be executed, authenticated and delivered in
accordance with the Agreement to the applicable Transferee.

          None of the Depositor, the Trustee or the Certificate Registrar is
obligated to register or qualify the Class of Certificates to which this
Certificate belongs, under the Securities Act or any other securities law or to
take any action not otherwise required under the Agreement to permit the
Transfer of this Certificate or any interest herein without such registration or
qualification. Any Certificateholder or Certificate Owner desiring to effect a
Transfer of this Certificate or any interest herein shall, and does hereby agree
to, indemnify the Depositor, Lehman Brothers Inc., UBS Securities LLC, the
Trustee, any Fiscal Agent, the Master Servicer, the Special Servicer, the
Certificate Registrar and their respective Affiliates against any liability that
may result if such Transfer is not exempt from the registration and/or
qualification requirements of the Securities Act and any applicable state
securities laws or is not made in accordance with such federal and state laws.

          No Transfer of this Certificate or any interest herein shall be made

Agency, and this Certificate or an interest herein is being acquired by or on
behalf of a Plan in reliance on any of Prohibited Transaction Exemption 91-14, a
certification to the effect that such Plan (X) is an accredited investor as
defined in Rule 501(a)(1) of Regulation D of the Securities Act, (Y) is not
sponsored (within the meaning of Section 3(16)(B) of ERISA) by the Trustee, the
Depositor, any Mortgage Loan Seller, the Master Servicer, the Special Servicer,
any Sub-Servicer, any Person responsible for servicing an Outside Serviced Trust
Mortgage Loan or administering an Outside Administered REO Property, any
Exemption-Favored Party or any Mortgagor with respect to Mortgage Loans
constituting more than 5% of the aggregate unamortized principal balance of all
the Mortgage Loans determined as of the Closing Date, or by any Affiliate of
such Person, and (Z) agrees that it will obtain from each of its Transferees
that are Plans a written representation that such Transferee, if a Plan,
satisfies the requirements of the immediately preceding clauses (X) and (Y),
together with a written agreement that such Transferee will obtain from each of
its Transferees that are Plans a similar written representation regarding
satisfaction of the requirements of the immediately preceding clauses (X) and
(Y); or (iv) a certification of facts and an Opinion of Counsel which otherwise
establish to the reasonable satisfaction of the Trustee or such Certificate
Owner, as the case may be, that such Transfer will not result in a violation of
Section 406 or 407 of ERISA or Section 4975 of the Code or result in the
imposition of an excise tax under Section 4975 of the Code. If any Transferee of
this Certificate or any interest herein does not, in connection with the subject
Transfer, deliver to the Certificate Registrar (if this Certificate constitutes
a Definitive Certificate) or the Transferor (if this Certificate constitutes a
Global Certificate) a certification and/or Opinion of Counsel as required by the
preceding sentence, then such Transferee shall be deemed to have represented and
warranted that either: (i) such Transferee is not a Plan and is not directly or
indirectly purchasing this Certificate or any interest herein on behalf of, as
named fiduciary of, as trustee of, or with assets of a Plan; or (ii) the
purchase and holding of this Certificate or such interest herein by such
Transferee is exempt from the prohibited transaction provisions of Sections
406(a) and (b) and 407 of ERISA and the excise taxes imposed on such prohibited
transactions by Sections 4975(a) and (b) of the Code.

          No service charge will be imposed for any registration of transfer or
exchange of Certificates, but the Trustee or the Certificate Registrar may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any transfer or exchange of
Certificates.

          [FOR BOOK ENTRY CERTIFICATES: Notwithstanding the foregoing, for so
long as this Certificate is registered in the name of Cede & Co. or in such
other name as is requested by an authorized representative of DTC, transfers of
interests in this Certificate shall be made through the book-entry facilities of
DTC.]

          The Holder of this Certificate, by its acceptance hereof, shall be
deemed to have agreed to keep confidential any information it obtains from the
Trustee (except that such Holder may provide any such information obtained by it
to any other Person that holds or is contemplating the purchase of this
Certificate or an interest herein, provided that such other Person confirms in
writing such ownership interest or prospective ownership interest and agrees to
keep such information confidential). Notwithstanding the foregoing, each offeree
and/or holder of this Certificate (and each employee, representative, or other
agent of such offeree or holder) may disclose to any and all persons, without


                                     A-4-8



limitation of any kind, the tax treatment and tax structure of the transactions
(as defined in section 1.6011-4 of the Treasury Department regulations)
associated herewith and all materials of any kind (including opinions or other
tax analyses) that are provided to the taxpayer relating to such tax treatment
and tax structure.

          Prior to due presentment of this Certificate for registration of
transfer, the Depositor, the Master Servicer, the Special Servicer, the Trustee,
the Certificate Registrar and any agents of any of them may treat the Person in
whose name this Certificate is registered as the owner hereof for all purposes,
and none of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Certificate Registrar or any such agent shall be affected by notice
to the contrary.

          Subject to certain terms and conditions set forth in the Agreement,
the Trust and the obligations created by the Agreement shall terminate upon
distribution (or provision for distribution) to the Certificateholders of all
amounts held by or on behalf of the Trustee and required to be distributed to
them pursuant to the Agreement following the earlier of (i) the final payment
(or any advance with respect thereto) on or other liquidation of the last
Mortgage Loan or REO Property remaining in the Trust, and (ii) the purchase by
the Depositor, Lehman Brothers Inc., the Master Servicer, the Special Servicer
or any Controlling Class Certificateholder at a price determined as provided in
the Agreement of all Mortgage Loans and any REO Properties remaining in the
Trust. The Agreement permits, but does not require, any Controlling Class
Certificateholder (with priority among such Holders being given to the Holder of
Certificates representing the greatest Percentage Interest in the Controlling
Class), the Special Servicer, the Master Servicer, the Depositor or Lehman
Brothers Inc., in that order of priority (with the Controlling Class
Certificateholder having the most senior priority) to purchase from the Trust
all Mortgage Loans and any REO Properties remaining therein. The exercise of
such right will effect early retirement of the Certificates; however, such right
to purchase is subject to the aggregate Stated Principal Balance of the Mortgage
Pool at the time of purchase being less than 1.0% of the initial aggregate
Certificate Principal Balance of all of the Principal Balance Certificates.

          The Agreement permits, with certain exceptions therein provided, the
amendment thereof, and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and any Fiscal
Agent thereunder and the rights of the Certificateholders thereunder, at any
time by the Depositor, the Master Servicer, the Special Servicer, the Trustee
and any Fiscal Agent with the consent of the Holders of Certificates entitled to
at least 66-2/3% of the Voting Rights allocated to the affected Classes. Any
such consent by the Holder of this Certificate shall be conclusive and binding
on such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain circumstances,
including any amendment necessary to maintain the status of any REMIC Pool as a
REMIC, without the consent of the Holders of any of the Certificates.

          Unless the certificate of authentication hereon has been executed by
the Authenticating Agent, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

          The registered Holder hereof, by its acceptance hereof, agrees that it
will look solely to the Trust (to the extent of its rights therein) for
distributions hereunder.


                                     A-4-9



          This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, without applying any conflicts of law principles of such state
(other than the provisions of Section 5-1401 of the New York General Obligations
Law), and the obligations, rights and remedies of the Holder hereof shall be
determined in accordance with such laws.


                                     A-4-10



          IN WITNESS WHEREOF, the Certificate Registrar has caused this
Certificate to be duly executed.

EXTENT PROVIDED IN THE POOLING AND SERVICING AGREEMENT REFERRED TO HEREIN.

SOLELY FOR U.S. FEDERAL INCOME TAX PURPOSES, THIS CERTIFICATE IS A "RESIDUAL

          This certifies that _______________________________ is the registered
owner of the Percentage Interest evidenced by this Certificate (as specified
above) in that certain beneficial ownership


                                     A-5-2



interest in the Trust evidenced by all the Certificates of the same Class as
this Certificate. The Trust was created and the Certificates were issued
pursuant to a Pooling and Servicing Agreement, dated as specified above (the
"Agreement"), between Structured Asset Securities Corporation II, as depositor
(the "Depositor", which term includes any successor entity under the Agreement),
Wachovia Bank, National Association, as master servicer (the "Master Servicer",
which term includes any successor entity under the Agreement), LNR Partners,
Inc., as special servicer (the "Special Servicer", which term includes any
successor entity under the Agreement), and LaSalle Bank National Association, as
trustee (the "Trustee", which term includes any successor entity under the
Agreement), a summary of certain of the pertinent provisions of which is set
forth hereafter. To the extent not defined herein, the capitalized terms used
herein have the respective meanings assigned in the Agreement. This Certificate
is issued under and is subject to the terms, provisions and conditions of the
Agreement, to which Agreement the Holder of this Certificate by virtue of the
acceptance hereof assents and by which such Holder is bound. In the event of any
conflict between any provision of this Certificate and any provision of the
Agreement, such provision of this Certificate shall be superseded to the extent
of such inconsistency.

          Pursuant to the terms of the Agreement, distributions will be made on
the 4th Business Day following the 11th calendar day of each month (or, if such
11th calendar day is not a Business Day, then the 5th Business Day following
such 11th calendar day) (each, a "Distribution Date"), commencing on the first
Distribution Date specified above, to the Person in whose name this Certificate
is registered at the close of business on the last Business Day of the month
immediately preceding the month of such distribution (the "Record Date"), in an
amount equal to the product of the Percentage Interest evidenced by this
Certificate and the amount required to be distributed pursuant to the Agreement
on the applicable Distribution Date in respect of the Class of Certificates to
which this Certificate belongs, provided that, in the case of the initial
Distribution Date, the Record Date shall be the Closing Date. All distributions
made under the Agreement in respect of this Certificate will be made by the
Trustee by wire transfer in immediately available funds to the account of the
Person entitled thereto at a bank or other entity having appropriate facilities
therefor, if such Certificateholder shall have provided the Trustee with written
wiring instructions generally no less than five (5) Business Days prior to (or,
in the case of the first such distribution, no later than) the Record Date for
such distribution (which wiring instructions may be in the form of a standing
order applicable to all subsequent distributions as well), or otherwise by check
mailed to the address of such Certificateholder appearing in the Certificate
Register. Notwithstanding the above, the final distribution in respect of this
Certificate will be made after due notice by the Trustee of the pendency of such
distribution and only upon presentation and surrender of this Certificate at the
offices of the Certificate Registrar appointed as provided in the Agreement or
such other location as may be specified in such notice.

          The Certificates are limited in right of distribution to certain
collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Custodial Accounts, the Collection Account and,
if established, the REO Accounts may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such advances and expenses.

          The Certificates are issuable in fully registered form only without
coupons in minimum denominations specified in the Agreement. As provided in the
Agreement and subject to certain limitations therein set forth, the Certificates
are exchangeable for new Certificates of the same Class in


                                     A-5-3



authorized denominations evidencing the same aggregate Percentage Interest, as
requested by the Holder surrendering the same.

          As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Certificates of the same
Class in authorized denominations evidencing the same aggregate Percentage
Interest will be issued to the designated transferee or transferees.

          No direct or indirect transfer, sale, pledge, hypothecation or other
disposition (each, a "Transfer") of this Certificate or any interest herein
shall be made unless that Transfer is exempt from the registration and/or
qualification requirements of the Securities Act and any applicable state
securities laws, or is otherwise made in accordance with the Securities Act and
such state securities laws.

          If a Transfer of this Certificate is to be made without registration
under the Securities Act (other than in connection with the initial issuance of
the Certificates or a Transfer of this Certificate by the Depositor, Lehman
Brothers Inc. or any of their respective Affiliates), then the Certificate
Registrar shall refuse to register such Transfer unless it receives (and, upon
receipt, may conclusively rely upon) either: (i) a certificate from the
Certificateholder desiring to effect such Transfer substantially in the form
attached as Exhibit F-1 to the Agreement and a certificate from such
Certificateholder's prospective Transferee substantially in the form attached as
Exhibit F-2A to the Agreement; or (ii) an Opinion of Counsel satisfactory to the
Trustee to the effect that such Transferee is a Qualified Institutional Buyer
and such Transfer may be made without registration under the Securities Act
(which Opinion of Counsel shall not be an expense of the Trust Fund or of the
Depositor, the Master Servicer, the Special Servicer, the Trustee, any Fiscal
Agent or the Certificate Registrar in their respective capacities as such),
together with the written certification(s) as to the facts surrounding such
Transfer from the Certificateholder desiring to effect such Transfer and/or such
Certificateholder's prospective Transferee on which such Opinion of Counsel is
based. If any Transferee of this Certificate does not, in connection with the
subject Transfer, deliver to the Certificate Registrar the certification
described in clause (i) of the preceding sentence or the Opinion of Counsel
described in clause (ii) of the preceding sentence, then such Transferee shall
be deemed to have represented and warranted that all the certifications set
forth in Exhibit F-2A attached to the Agreement are, with respect to the subject
Transfer, true and correct. Residual Interest Certificates may only be held by
Qualified Institutional Buyers, and each other Definitive Non-Registered
Certificate may only be held by Qualified Institutional Buyers and Institutional
Accredited Investors.

          None of the Depositor, the Trustee or the Certificate Registrar is
obligated to register or qualify the Class of Certificates to which this
Certificate belongs, under the Securities Act or any other securities law or to
take any action not otherwise required under the Agreement to permit the
Transfer of this Certificate or any interest herein without such registration or
qualification. Any Certificateholder desiring to effect a Transfer of this
Certificate or any interest herein shall, and does hereby agree to, indemnify
the Depositor, Lehman Brothers Inc., UBS Securities LLC, the Trustee, any Fiscal
Agent, the Master Servicer, the Special Servicer, the Certificate Registrar and
their respective Affiliates against any liability that may result if such
Transfer is not exempt from the registration and/or qualification


                                     A-5-4



requirements of the Securities Act and any applicable state securities laws or
is not made in accordance with such federal and state laws.

          No Transfer of this Certificate or any interest herein shall be made
to (A) any employee benefit plan or other retirement arrangement, including
individual retirement accounts and annuities, Keogh plans and collective
investment funds and separate accounts in which such plans, accounts or
arrangements are invested, including insurance company general accounts, that is
subject to ERISA or the Code (each, a "Plan"), or (B) any Person who is directly
or indirectly purchasing this Certificate or such interest herein on behalf of,
as named fiduciary of, as trustee of, or with assets of a Plan, if the purchase
and holding of this Certificate or such interest herein by the prospective
Transferee would result in a violation of Section 406 or 407 of ERISA or Section
4975 of the Code or would result in the imposition of an excise tax under
Section 4975 of the Code. Except in connection with the initial issuance of the
Certificates or any Transfer of this Certificate by the Depositor, Lehman
Brothers Inc. or any of their respective Affiliates, the Certificate Registrar
shall refuse to register the Transfer of this Certificate unless it has received
from the prospective Transferee, either: (i) a certification to the effect that
such prospective Transferee is not a Plan and is not directly or indirectly
purchasing this Certificate on behalf of, as named fiduciary of, as trustee of,
or with assets of a Plan; or (ii) a certification of facts and an Opinion of
Counsel which otherwise establish to the reasonable satisfaction of the Trustee
that such Transfer will not result in a violation of Section 406 or 407 of ERISA
or Section 4975 of the Code or result in the imposition of an excise tax under
Section 4975 of the Code. If any Transferee of this Certificate or any interest
herein does not, in connection with the subject Transfer, deliver to the
Certificate Registrar a certification and/or Opinion of Counsel as required by
the preceding sentence, then such Transferee shall be deemed to have represented
and warranted that either: (i) such Transferee is not a Plan and is not directly
or indirectly purchasing this Certificate or such interest herein on behalf of,
as named fiduciary of, as trustee of, or with assets of a Plan; or (ii) the
purchase and holding of this Certificate or such interest herein by such
Transferee is exempt from the prohibited transaction provisions of Sections
406(a) and (b) and 407 of ERISA and the excise taxes imposed on such prohibited
transactions by Sections 4975(a) and (b) of the Code.

          Each Person who has or who acquires any Ownership Interest in this
Certificate shall be deemed by the acceptance or acquisition of such Ownership
Interest to have agreed to be bound by the provisions of Section 5.02(d) of the
Agreement and, if any purported Transferee shall become a Holder of this
Certificate in violation of the provisions of such Section 5.02(d), to have
irrevocably authorized the Trustee under clause (ii)(A) of such Section 5.02(d)
to deliver payments to a Person other than such Person and to have irrevocably
authorized the Trustee under clause (ii)(B) of such Section 5.02(d) to negotiate
the terms of any mandatory disposition and to execute all instruments of
transfer and to do all other things necessary in connection with any such
disposition. Each Person holding or acquiring any Ownership Interest in this
Certificate must be a Permitted Transferee and shall promptly notify the Trustee
and the Tax Administrator of any change or impending change in its status as a
Permitted Transferee. In connection with any proposed Transfer of any Ownership
Interest in this Certificate, the Certificate Registrar shall require delivery
to it, and shall not register the transfer of this Certificate until its receipt
of, an affidavit and agreement substantially in the form attached as Exhibit H-1
to the Agreement (a "Transfer Affidavit and Agreement") from the proposed
Transferee, representing and warranting, among other things, that such
Transferee is a Permitted Transferee, that it is not acquiring its Ownership
Interest in this Certificate as a nominee, trustee or agent for any Person that
is not a Permitted Transferee, that for so long as it retains its Ownership
Interest in this Certificate, it will endeavor to remain a Permitted Transferee,
and that it has reviewed the provisions of Section 5.02(d) of


                                     A-5-5



the Agreement and agrees to be bound by them. Notwithstanding the delivery of a
Transfer Affidavit and Agreement by a proposed Transferee, if the Certificate
Registrar has actual knowledge that the proposed Transferee is not a Permitted
Transferee, the Certificate Registrar shall not register the Transfer of an
Ownership Interest in this Certificate to such proposed Transferee. In addition,
the Certificate Registrar shall not register the transfer of an Ownership
Interest in this Certificate to any entity classified as a partnership under the
Code unless at the time of transfer, all of its beneficial owners are United
States Tax Persons.

          Each Person holding or acquiring any Ownership Interest in this
Certificate shall agree (x) to require a Transfer Affidavit and Agreement from
any other Person to whom such Person attempts to Transfer its Ownership Interest
herein and (y) not to Transfer its Ownership Interest herein unless it provides
to the Certificate Registrar a certificate substantially in the form attached as
Exhibit H-2 to the Agreement stating that, among other things, it has no actual
knowledge that such other Person is not a Permitted Transferee. Each Person
holding or acquiring an Ownership Interest in this Certificate, by purchasing
such Ownership Interest herein, agrees to give the Trustee and the Tax
Administrator written notice that it is a "pass-through interest holder" within
the meaning of temporary Treasury regulations section 1.67-3T(a)(2)(i)(A)
immediately upon acquiring such Ownership Interest, if it is, or is holding such
Ownership Interest on behalf of, a "pass-through interest holder".

          The provisions of Section 5.02(d) of the Agreement may be modified,
added to or eliminated, provided that there shall have been delivered to the
Trustee and the Tax Administrator the following: (a) written notification from
each Rating Agency to the effect that the modification of, addition to or
elimination of such provisions will not cause such Rating Agency to withdraw,
qualify or downgrade its then-current rating of any Class of Certificates; and
(b) an opinion of counsel, in form and substance satisfactory to the Trustee and
the Tax Administrator, to the effect that such modification of, addition to or
elimination of such provisions will not (i) cause any REMIC Pool to (A) cease to
qualify as a REMIC or (B) be subject to an entity-level tax caused by the
Transfer of a Residual Interest Certificate to a Person which is not a Permitted
Transferee, or (ii) cause a Person other than the prospective Transferee to be
subject to a REMIC-related tax caused by the Transfer of a Residual Interest
Certificate to a Person that is not a Permitted Transferee.

          A "Permitted Transferee" is any Transferee that is not (i) a
Disqualified Organization, (ii) any Person as to whom the transfer of this
Certificate may cause any REMIC Pool to fail to qualify as a REMIC, (iii) a
Disqualified Non-United States Tax Person, (iv) a Disqualified Partnership or
(v) a foreign permanent establishment or fixed base (within the meaning of any
applicable income tax treaty between the United States and any foreign
jurisdiction) of a United States Tax Person.

          A "Disqualified Organization" is (i) the United States, any State or
political subdivision thereof, a foreign government, an international
organization, or any agency or instrumentality of any of the foregoing, (ii) any
organization (other than certain farmers' cooperatives described in Section 521
of the Code) that is exempt from the tax imposed by Chapter 1 of the Code
(including the tax imposed by Section 511 of the Code on unrelated business
taxable income), (iii) rural electric and telephone cooperatives described in
Section 1381 of the Code and (iv) any other Person so designated by the Trustee
or the Tax Administrator based upon an opinion of counsel that the holding of an
Ownership Interest in a Residual Interest Certificate by such Person may cause
the Trust or any Person having an Ownership Interest in any Class of
Certificates (other than such Person) to incur a liability for any federal tax
imposed under the Code that would not otherwise be imposed but for the Transfer
of an


                                     A-5-6



Ownership Interest in a Residual Interest Certificate to such Person. The terms
"United States", "State" and "international organization" shall have the
meanings set forth in Section 7701 of the Code or successor provisions.

          A "Disqualified Non-United States Tax Person" is, with respect to any
Residual Interest Certificate, any Non-United States Tax Person or agent thereof
other than: (1) a Non-United States Tax Person that (a) holds such Residual
Interest Certificate and, for purposes of Treasury regulations section
1.860G-3(a)(3), is subject to tax under Section 882 of the Code, (b) certifies
that it understands that, for purposes of Treasury regulations section
1.860E-1(c)(4)(ii), as a holder of such Residual Interest Certificate for United

any cash flows generated by such Residual Interest Certificate and intends to
pay taxes associated with holding such Residual Interest Certificate, and (c)
has furnished the Transferor and the Trustee with an effective IRS Form W-8ECI
or successor form and has agreed to update such form as required under the
applicable Treasury regulations; or (2) a Non-United States Tax Person that has
delivered to the Transferor, the Trustee and the Certificate Registrar an
opinion of nationally recognized tax counsel to the effect that (x) the Transfer
of such Residual Interest Certificate to it is in accordance with the
requirements of the Code and the regulations promulgated thereunder and (y) such
Transfer of such Residual Interest Certificate will not be disregarded for
United States federal income tax purposes.

          A "Disqualified Partnership" is any domestic entity classified as a
partnership under the Code, if any of its beneficial owners are Disqualified
Non-United States Tax Persons.

          A "Non-United States Tax Person" is any Person other than a United
States Tax Person. A "United States Tax Person" is a citizen or resident of the
United States, a corporation, partnership or other entity created or organized
in, or under the laws of, the United States or any political subdivision
thereof, or an estate whose income from sources without the United States is
includable in gross income for United States federal income tax purposes
regardless of its connection with the conduct of a trade or business within the
United States, or a trust if a court within the United States is able to
exercise supervision over the administration of the trust and one or more United
States persons have the authority to control all substantial decisions of the
trust (or to the extent provided in the Treasury regulations, if the trust was
in existence on August 20, 1996 and elected to be treated as a United States
person), all within the meaning of Section 7701(a)(30) of the Code.

          No service charge will be imposed for any registration of transfer or
exchange of Certificates, but the Trustee or the Certificate Registrar may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any transfer or exchange of
Certificates.

          The Holder of this Certificate, by its acceptance hereof, shall be
deemed to have agreed to keep confidential any information it obtains from the
Trustee (except that such Holder may provide any such information obtained by it
to any other Person that holds or is contemplating the purchase of this
Certificate or an interest herein, provided that such other Person confirms in
writing such ownership interest or prospective ownership interest and agrees to
keep such information confidential). Notwithstanding the foregoing, each offeree
and/or holder of this Certificate (and each employee, representative, or other
agent of such offeree or holder) may disclose to any and all persons, without
limitation of any kind, the tax treatment and tax structure of the transactions
(as defined in section 1.6011-4 of the Treasury Department regulations)
associated herewith and all materials of any kind


                                     A-5-7



(including opinions or other tax analyses) that are provided to the taxpayer
relating to such tax treatment and tax structure.

          Prior to due presentment of this Certificate for registration of
transfer, the Depositor, the Master Servicer, the Special Servicer, the Trustee,
the Certificate Registrar and any agents of any of them may treat the Person in
whose name this Certificate is registered as the owner hereof for all purposes,
and none of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Certificate Registrar or any such agent shall be affected by notice
to the contrary.

          Subject to certain terms and conditions set forth in the Agreement,
the Trust and the obligations created by the Agreement shall terminate upon
distribution (or provision for distribution) to the Certificateholders of all
amounts held by or on behalf of the Trustee and required to be distributed to
them pursuant to the Agreement following the earlier of (i) the final payment
(or any advance with respect thereto) on or other liquidation of the last
Mortgage Loan or REO Property remaining in the Trust, and (ii) the purchase by
the Depositor, Lehman Brothers Inc., the Master Servicer, the Special Servicer
or any Controlling Class Certificateholder at a price determined as provided in
the Agreement of all Mortgage Loans and any REO Properties remaining in the
Trust. The Agreement permits, but does not require, any Controlling Class
Certificateholder (with priority among such Holders being given to the Holder of
Certificates representing the greatest Percentage Interest in the Controlling
Class), the Special Servicer, the Master Servicer, the Depositor or Lehman
Brothers Inc., in that order of priority (with the Controlling Class
Certificateholder having the most senior priority) to purchase from the Trust
all Mortgage Loans and any REO Properties remaining therein. The exercise of
such right will effect early retirement of the Certificates; however, such right
to purchase is subject to the aggregate Stated Principal Balance of the Mortgage
Pool at the time of purchase being less than 1.0% of the initial aggregate
Certificate Principal Balance of all of the Principal Balance Certificates.

          The Agreement permits, with certain exceptions therein provided, the
amendment thereof, and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and any Fiscal
Agent thereunder and the rights of the Certificateholders thereunder, at any
time by the Depositor, the Master Servicer, the Special Servicer, the Trustee
and any Fiscal Agent with the consent of the Holders of Certificates entitled to
at least 66-2/3% of the Voting Rights allocated to the affected Classes. Any
such consent by the Holder of this Certificate shall be conclusive and binding
on such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain circumstances,
including any amendment necessary to maintain the status of any REMIC Pool as a
REMIC, without the consent of the Holders of any of the Certificates.

          Unless the certificate of authentication hereon has been executed by
the Authenticating Agent, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

          The registered Holder hereof, by its acceptance hereof, agrees that it
will look solely to the Trust (to the extent of its rights therein) for
distributions hereunder.

          This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, without applying any conflicts of law principles of such state
(other than the provisions of Section 5-1401 of the New York


                                     A-5-8



General Obligations Law), and the obligations, rights and remedies of the Holder
hereof shall be determined in accordance with such laws.


                                     A-5-9



          IN WITNESS WHEREOF, the Certificate Registrar has caused this
Certificate to be duly executed.

                                      A-6-3



          If a Transfer of this Certificate is to be made without registration
under the Securities Act (other than in connection with the initial issuance of
the Certificates or a Transfer of this Certificate by the Depositor, Lehman
Brothers Inc. or any of their respective Affiliates), then the Certificate
Registrar shall refuse to register such Transfer unless it receives (and, upon
receipt, may conclusively rely upon) either: (i) a certificate from the
Certificateholder desiring to effect such Transfer substantially in the form
attached as Exhibit F-1 to the Agreement and a certificate from such
Certificateholder's prospective Transferee substantially in the form attached
either as Exhibit F-2A to the Agreement or as Exhibit F-2B to the Agreement; or
(ii) an Opinion of Counsel satisfactory to the Trustee to the effect that such
Transferee is an Institutional Accredited Investor or a Qualified Institutional
Buyer and such Transfer may be made without registration under the Securities
Act (which Opinion of Counsel shall not be an expense of the Trust Fund or of
the Depositor, the Master Servicer, the Special Servicer, the Trustee, any
Fiscal Agent or the Certificate Registrar in their respective capacities as
such), together with the written certification(s) as to the facts surrounding
such Transfer from the Certificateholder desiring to effect such Transfer and/or
such Certificateholder's prospective Transferee on which such Opinion of Counsel
is based. If any Transferee of this Certificate does not, in connection with the
subject Transfer, deliver to the Certificate Registrar one of the certifications
described in clause (i) of the preceding sentence or the Opinion of Counsel
described in clause (ii) of the preceding sentence, then such Transferee shall
be deemed to have represented and warranted that all the certifications set
forth in either Exhibit F-2A or Exhibit F-2B attached to the Agreement are, with
respect to the subject Transfer, true and correct. Definitive Non-Registered
Certificates may only be held by Qualified Institutional Buyers and
Institutional Accredited Investors.

          None of the Depositor, the Trustee or the Certificate Registrar is
obligated to register or qualify the Class of Certificates to which this
Certificate belongs, under the Securities Act or any other securities law or to
take any action not otherwise required under the Agreement to permit the
Transfer of this Certificate or any interest herein without such registration or
qualification. Any Certificateholder desiring to effect a Transfer of this
Certificate or any interest herein shall, and does hereby agree to, indemnify
the Depositor, Lehman Brothers Inc., UBS Securities LLC, the Trustee, any Fiscal
Agent, the Master Servicer, the Special Servicer, the Certificate Registrar and
their respective Affiliates against any liability that may result if such
Transfer is not exempt from the registration and/or qualification requirements
of the Securities Act and any applicable state securities laws or is not made in
accordance with such federal and state laws.

          No Transfer of this Certificate or any interest herein shall be made
to (A) any employee benefit plan or other retirement arrangement, including
individual retirement accounts and annuities, Keogh plans and collective
investment funds and separate accounts in which such plans, accounts or
arrangements are invested, including insurance company general accounts, that is
subject to ERISA or the Code (each, a "Plan"), or (B) any Person who is directly
or indirectly purchasing this Certificate or such interest herein on behalf of,
as named fiduciary of, as trustee of, or with assets of a Plan, if the purchase
and holding of this Certificate or such interest herein by the prospective
Transferee would result in a violation of Section 406 or 407 of ERISA or Section
4975 of the Code or would result in the imposition of an excise tax under
Section 4975 of the Code. Except in connection with the initial issuance of the
Certificates or any Transfer of this Certificate by the Depositor, Lehman
Brothers Inc. or any of their respective Affiliates, the Certificate Registrar
shall refuse to register the Transfer of this Certificate unless it has received
from the prospective Transferee, either: (i) a certification to the effect that
such prospective Transferee is not a Plan and is not directly or indirectly
purchasing this Certificate or such interest herein on behalf of, as named
fiduciary of, as trustee of, or with assets of a Plan; or (ii) a


                                      A-6-4



certification of facts and an Opinion of Counsel which otherwise establish to
the reasonable satisfaction of the Trustee that such Transfer will not result in
a violation of Section 406 or 407 of ERISA or Section 4975 of the Code or result
in the imposition of an excise tax under Section 4975 of the Code. If any
Transferee of this Certificate or any interest herein does not, in connection
with the subject Transfer, deliver to the Certificate Registrar a certification
and/or Opinion of Counsel as required by the preceding sentence, then such
Transferee shall be deemed to have represented and warranted that either: (i)
such Transferee is not a Plan and is not directly or indirectly purchasing this
Certificate on behalf of, as named fiduciary of, as trustee of, or with assets
of a Plan; or (ii) the purchase and holding of this Certificate or such interest
herein by such Transferee is exempt from the prohibited transaction provisions
of Sections 406(a) and (b) and 407 of ERISA and the excise taxes imposed on such
prohibited transactions by Sections 4975(a) and (b) of the Code.

          No service charge will be imposed for any registration of transfer or
exchange of Certificates, but the Trustee or the Certificate Registrar may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any transfer or exchange of
Certificates.

          The Holder of this Certificate, by its acceptance hereof, shall be
deemed to have agreed to keep confidential any information it obtains from the
Trustee (except that such Holder may provide any such information obtained by it
to any other Person that holds or is contemplating the purchase of this
Certificate or an interest herein, provided that such other Person confirms in
writing such ownership interest or prospective ownership interest and agrees to
keep such information confidential). Notwithstanding the foregoing, each offeree
and/or holder of this Certificate (and each employee, representative, or other
agent of such offeree or holder) may disclose to any and all persons, without
limitation of any kind, the tax treatment and tax structure of the transactions
(as defined in section 1.6011-4 of the Treasury Department regulations)
associated herewith and all materials of any kind (including opinions or other
tax analyses) that are provided to the taxpayer relating to such tax treatment
and tax structure.

          Prior to due presentment of this Certificate for registration of
transfer, the Depositor, the Master Servicer, the Special Servicer, the Trustee,
the Certificate Registrar and any agents of any of them may treat the Person in
whose name this Certificate is registered as the owner hereof for all purposes,
and none of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Certificate Registrar or any such agent shall be affected by notice
to the contrary.

          Subject to certain terms and conditions set forth in the Agreement,
the Trust and the obligations created by the Agreement shall terminate upon
distribution (or provision for distribution) to the Certificateholders of all
amounts held by or on behalf of the Trustee and required to be distributed to
them pursuant to the Agreement following the earlier of (i) the final payment
(or any advance with respect thereto) on or other liquidation of the last
Mortgage Loan or REO Property remaining in the Trust, and (ii) the purchase by
the Depositor, Lehman Brothers Inc., the Master Servicer, the Special Servicer
or any Controlling Class Certificateholder at a price determined as provided in
the Agreement of all Mortgage Loans and any REO Properties remaining in the

                                      A-6-5

such right will effect early retirement of the Certificates; however, such right
to purchase is subject to the aggregate Stated Principal Balance of the Mortgage
Pool at the time of purchase being less than 1.0% of the initial aggregate
Certificate Principal Balance of all of the Principal Balance Certificates.

Agent thereunder and the rights of the Certificateholders thereunder, at any
time by the Depositor, the Master Servicer, the Special Servicer, the Trustee
and any Fiscal Agent with the consent of the Holders of Certificates entitled to
at least 66-2/3% of the Voting Rights allocated to the affected Classes. Any
such consent by the Holder of this Certificate shall be conclusive and binding
on such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain circumstances,
including any amendment necessary to maintain the status of any REMIC Pool as a
REMIC, without the consent of the Holders of any of the Certificates.

          Unless the certificate of authentication hereon has been executed by
the Authenticating Agent, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

          The registered Holder hereof, by its acceptance hereof, agrees that it
will look solely to the Trust (to the extent of its rights therein) for
distributions hereunder.

          This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, without applying any conflicts of law principles of such state
(other than the provisions of Section 5-1401 of the New York General Obligations
Law), and the obligations, rights and remedies of the Holder hereof shall be
determined in accordance with such laws.

Agreement the Holder of this Certificate by virtue of the acceptance hereof

provision of this Certificate shall be superseded to the extent of such
inconsistency.

          Pursuant to the terms of the Agreement, distributions will be made on
the 4th Business Day following the 11th calendar day of each month (or, if such
11th calendar day is not a Business Day, then the 5th Business Day following

disposition (each, a "Transfer") of this Certificate or any interest herein
shall be made unless that Transfer is exempt from the registration and/or
qualification requirements of the Securities Act and any applicable state
securities laws, or is otherwise made in accordance with the Securities Act and
such state securities laws.

          If this Certificate constitutes a Definitive Certificate and a
Transfer hereof is to be made without registration under the Securities Act
(other than in connection with the initial issuance of the Certificates or a
Transfer of this Certificate by the Depositor, Lehman Brothers Inc. or any of
their


                                     A-7-5



respective Affiliates or, if this Certificate is a Global Certificate, a
Transfer of this Certificate to a successor Depository or to the applicable
Certificate Owner in accordance with Section 5.03 of the Agreement), then the
Certificate Registrar shall refuse to register such Transfer unless it receives
(and, upon receipt, may conclusively rely upon) either: (i) a certificate from
the Certificateholder desiring to effect such Transfer substantially in the form
attached as Exhibit F-1 to the Agreement and a certificate from such
Certificateholder's prospective Transferee substantially in the form attached
either as Exhibit F-2A to the Agreement or as Exhibit F-2B to the Agreement; or
(ii) an Opinion of Counsel satisfactory to the Trustee to the effect that such

Buyer and such Transfer may be made without registration under the Securities
Act (which Opinion of Counsel shall not be an expense of the Trust Fund or of
the Depositor, the Master Servicer, the Special Servicer, the Trustee, any
Fiscal Agent or the Certificate Registrar in their respective capacities as
such), together with the written certification(s) as to the facts surrounding
such Transfer from the Certificateholder desiring to effect such Transfer and/or
such Certificateholder's prospective Transferee on which such Opinion of Counsel
is based. If any Transferee of this Certificate does not, in connection with the
subject Transfer, deliver to the Certificate Registrar one of the certifications
described in clause (i) of the preceding sentence or the Opinion of Counsel
described in clause (ii) of the preceding sentence, then such Transferee shall
be deemed to have represented and warranted that all the certifications set
forth in either Exhibit F-2A or Exhibit F-2B attached to the Agreement are, with
respect to the subject Transfer, true and correct. Definitive Non-Registered
Certificates may only be held by Qualified Institutional Buyers and
Institutional Accredited Investors.

          No beneficial interest in a Rule 144A Global Certificate for any Class
of Book-Entry Non-Registered Certificates may be held by any Person that is not
a Qualified Institutional Buyer. If this Certificate constitutes a Rule 144A
Global Certificate and a Transfer of any interest herein is to be made without
registration under the Securities Act (other than in connection with the initial
issuance of the Certificates or a Transfer of any interest herein by the
Depositor, Lehman Brothers Inc. or any of their respective Affiliates), then the
Certificate Owner desiring to effect such Transfer shall be required to obtain
either (i) a certificate from such Certificate Owner's prospective Transferee
substantially in the form attached as Exhibit F-2C to the Agreement, or (ii) an
Opinion of Counsel to the effect that such Transferee is a Qualified
Institutional Buyer and such Transfer may be made without registration under the
Securities Act. If this Certificate constitutes a Rule 144A Global Certificate
and any Transferee of an interest herein does not, in connection with the
subject Transfer, deliver to the Transferor the Opinion of Counsel or the
certification described in the preceding sentence, then such Transferee shall be
deemed to have represented and warranted that all the certifications set forth
in Exhibit F-2C attached to the Agreement are, with respect to the subject
Transfer, true and correct. Furthermore, if this Certificate constitutes a Rule
144A Global Certificate for the Class T Certificates and a Transfer of any
interest herein is to be made without registration under the Securities Act, any
Certificate Owner desiring to effect a transfer of this Certificate or any
interest herein may not sell or otherwise transfer this Certificate or any
interest herein unless it has provided the Depositor with prior written notice
of such transfer (together with a copy of the certificate (executed by the
proposed transferee) or Opinion of Counsel referred to above in this paragraph);
such notice to be delivered to Structured Asset Securities Corporation II, 745
Seventh Avenue, New York, New York 10019, Attention: Scott Lechner--LB-UBS

          Notwithstanding the preceding paragraph, any interest in the Rule 144A
Global Certificate for a Class of Book-Entry Non-Registered Certificates may be
transferred to any Non-United States Securities Person who takes delivery in the
form of a beneficial interest in the Regulation S


                                     A-7-6



Global Certificate for such Class of Certificates, provided that the Certificate
Owner desiring to effect such Transfer (i) complies with the requirements for
Transfers of interests in such Regulation S Global Certificate set forth in the
following paragraph and (ii) delivers or causes to be delivered to the
Certificate Registrar and the Trustee (A) a certificate from such Certificate
Owner confirming its ownership of the beneficial interests in the subject Class
of Book-Entry Non-Registered Certificates to be transferred, (B) a copy of the
certificate to be obtained by such Certificate Owner from its prospective
Transferee in accordance with the second sentence of the following paragraph and
(C) such written orders and instructions as are required under the applicable
procedures of the Depository, Clearstream and Euroclear to direct the Trustee,
as transfer agent for the Depository, to approve the debit of the account of a
Depository Participant by a denomination of interests in such Rule 144A Global
Certificate, and approve the credit of the account of a Depository Participant
by a denomination of interests in such Regulation S Global Certificate, that is
equal to the denomination of beneficial interests in the subject Class of
Book-Entry Non-Registered Certificates to be transferred. Upon delivery to the
Certificate Registrar and the Trustee of such certifications and such orders and
instructions, the Trustee, subject to and in accordance with the applicable
procedures of the Depository, shall reduce the denomination of the Rule 144A
Global Certificate in respect of the subject Class of Book-Entry Non-Registered
Certificates, and increase the denomination of the Regulation S Global
Certificate for such Class of Certificates, by the denomination of the
beneficial interest in such Class of Certificates specified in such orders and
instructions.

          No beneficial interest in the Regulation S Global Certificate for any
Class of Book-Entry Non-Registered Certificates may be held by a United States
Securities Person. Any Certificate Owner desiring to effect any Transfer of an
interest in the Regulation S Global Certificate for any Class of Book-Entry
Non-Registered Certificates shall be required to obtain from such Certificate
Owner's prospective Transferee a certificate substantially in the form set forth
in Exhibit F-2D to the Agreement to the effect that such Transferee is not a
United States Securities Person. If any Transferee of an interest in the
Regulation S Global Certificate for any Class of Book-Entry Non-Registered
Certificates does not, in connection with the subject Transfer, deliver to the
Transferor the certification described in the preceding sentence, then such
Transferee shall be deemed to have represented and warranted that all the
certifications set forth in Exhibit F-2D to the Agreement are, with respect to
the subject Transfer, true and correct.

          Notwithstanding the preceding paragraph, any interest in the
Regulation S Global Certificate for a Class of Book-Entry Non-Registered
Certificates may be transferred to any Qualified Institutional Buyer that takes
delivery in the form of a beneficial interest in the Rule 144A Global
Certificate for such Class of Certificates, provided that the Certificate Owner
desiring to effect such transfer (i) complies with the requirements for
Transfers of interests in such Rule 144A Global Certificate set forth in the
third paragraph above this paragraph and (ii) delivers or causes to be delivered
to the Certificate Registrar and the Trustee (A) a certificate from such
Certificate Owner confirming its ownership of the beneficial interests in the
subject Class of Book-Entry Non-Registered Certificates to be transferred, (B) a
copy of the certificate or Opinion of Counsel to be obtained by such Certificate
Owner from its prospective Transferee in accordance with the second sentence of
the third paragraph above this paragraph and (C) such written orders and
instructions as are required under the applicable procedures of the Depository,
Clearstream and Euroclear to direct the Trustee to debit the account of a
Depository Participant by a denomination of interests in such Regulation S
Global Certificate, and credit the account of a Depository Participant by a
denomination of interests in such Rule 144A Global Certificate, that is equal to
the denomination of beneficial interests in the subject Class of Book-Entry


                                     A-7-7



Non-Registered Certificates to be transferred. Upon delivery to the Certificate
Registrar and the Trustee of such certification(s) and/or Opinion of Counsel and
such orders and instructions, the Trustee, subject to and in accordance with the
applicable procedures of the Depository, shall reduce the denomination of the
Regulation S Global Certificate in respect of the subject Class of Book-Entry
Non-Registered Certificates, and increase the denomination of the Rule 144A
Global Certificate for such Class of Certificates, by the denomination of the
beneficial interest in such Class of Certificates specified in such orders and
instructions.

          Also notwithstanding the foregoing, any interest in a Global
Certificate with respect to any Class of Book-Entry Non-Registered Certificates
may be transferred by any Certificate Owner holding such interest to any
Institutional Accredited Investor (other than a Qualified Institutional Buyer)
that takes delivery in the form of a Definitive Certificate of the same Class as
such Global Certificate upon delivery to the Certificate Registrar and the
Trustee of (i) such certifications and/or opinions as are contemplated by the
fifth paragraph above this paragraph and (ii) such written orders and
instructions as are required under the applicable procedures of the Depository
to direct the Trustee to debit the account of a Depository Participant by the
denomination of the transferred interests in such Global Certificate. Upon
delivery to the Certificate Registrar and the Trustee of the certifications
and/or opinions contemplated by the fifth paragraph above this paragraph, the
Trustee, subject to and in accordance with the applicable procedures of the
Depository, shall reduce the denomination of the subject Global Certificate by
the denomination of the transferred interests in such Global Certificate, and
shall cause a Definitive Certificate of the same Class as such Global
Certificate, and in a denomination equal to the reduction in the denomination of
such Global Certificate, to be executed, authenticated and delivered in

subject to ERISA or the Code (each, a "Plan"), or (B) any Person who is directly

4975 of the Code or would result in the imposition of an excise tax under
Section 4975 of the Code. Except in connection with the initial issuance of the

following: (i) a certification to the effect that such prospective Transferee is
not a Plan and is not directly or indirectly purchasing this Certificate or such
interest herein on behalf of, as named fiduciary of, as trustee of, or with
assets of a Plan; or (ii) a certification to the effect that the purchase and
holding of this Certificate or such interest herein by such prospective
Transferee is exempt from the prohibited transaction provisions of Sections

transactions by Sections 4975(a) and (b) of the Code, by reason of Sections I
and III of Prohibited Transaction Class Exemption 95-60; or (iii) if this
Certificate is rated in one of the four highest generic rating categories by
either Rating Agency, and this Certificate or an interest herein is being
acquired by or on behalf of a Plan in reliance on any of Prohibited Transaction
Exemption 91-14, a certification to the effect that such Plan (X) is an
accredited investor as defined in Rule 501(a)(1) of Regulation D of the
Securities Act, (Y) is not sponsored (within the meaning of Section 3(16)(B) of
ERISA) by the Trustee, the Depositor, any Mortgage Loan Seller, the Master
Servicer, the Special Servicer, any Sub-Servicer, any Person responsible for
servicing an Outside Serviced Trust Mortgage Loan or administering an Outside
Administered REO Property, any Exemption-Favored Party or any Mortgagor with
respect to Mortgage Loans constituting more than 5% of the aggregate unamortized
principal balance of all the Mortgage Loans determined as of the Closing Date,
or by any Affiliate of such Person, and (Z) agrees that it will obtain from each
of its Transferees that are Plans a written representation that such Transferee,
if a Plan, satisfies the requirements of the immediately preceding clauses (X)
and (Y), together with a written agreement that such Transferee will obtain from
each of its Transferees that are Plans a similar written representation
regarding satisfaction of the requirements of the immediately preceding clauses
(X) and (Y); or (iv) a certification of facts and an Opinion of Counsel which
otherwise establish to the reasonable satisfaction of the Trustee or such
Certificate Owner, as the case may be, that such Transfer will not result in a
violation of Section 406 or 407 of ERISA or Section 4975 of the Code or result
in the imposition of an excise tax under Section 4975 of the Code. If any
Transferee of this Certificate or any interest herein does not, in connection
with the subject Transfer, deliver to the Certificate Registrar (if this
Certificate constitutes a Definitive Certificate) or the Transferor (if this
Certificate constitutes a Global Certificate) a certification and/or Opinion of
Counsel as required by the preceding sentence, then such Transferee shall be
deemed to have represented and warranted that either: (i) such Transferee is not
a Plan and is not directly or indirectly purchasing this Certificate or any
interest herein on behalf of, as named fiduciary of, as trustee of, or with
assets of a Plan; or (ii) the purchase and holding of this Certificate or such
interest herein by such Transferee is exempt from the prohibited transaction
provisions of Sections 406(a) and (b) and 407 of ERISA and the excise taxes
imposed on such prohibited transactions by Sections 4975(a) and (b) of the Code.

          No service charge will be imposed for any registration of transfer or
exchange of Certificates, but the Trustee or the Certificate Registrar may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any transfer or exchange of
Certificates.

          [FOR BOOK ENTRY CERTIFICATES: Notwithstanding the foregoing, for so
long as this Certificate is registered in the name of Cede & Co. or in such
other name as is requested by an authorized representative of DTC, transfers of
interests in this Certificate shall be made through the book-entry facilities of

          The Holder of this Certificate, by its acceptance hereof, shall be
deemed to have agreed to keep confidential any information it obtains from the
Trustee (except that such Holder may provide any such information obtained by it
to any other Person that holds or is contemplating the purchase of this
Certificate or an interest herein, provided that such other Person confirms in
writing such ownership interest or prospective ownership interest and agrees to
keep such information confidential). Notwithstanding the foregoing, each offeree
and/or holder of this Certificate (and each employee, representative, or other
agent of such offeree or holder) may disclose to any and all persons, without
limitation of any kind, the tax treatment and tax structure of the transactions
(as defined in section 1.6011-4 of the Treasury Department regulations)
associated herewith and all materials of any kind (including opinions or other
tax analyses) that are provided to the taxpayer relating to such tax treatment
and tax structure.

          Prior to due presentment of this Certificate for registration of
transfer, the Depositor, the Master Servicer, the Special Servicer, the Trustee,
the Certificate Registrar and any agents of any of them may treat the Person in
whose name this Certificate is registered as the owner hereof for all purposes,
and none of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Certificate Registrar or any such agent shall be affected by notice
to the contrary.

          Subject to certain terms and conditions set forth in the Agreement,
the Trust and the obligations created by the Agreement shall terminate upon
distribution (or provision for distribution) to the Certificateholders of all
amounts held by or on behalf of the Trustee and required to be distributed to
them pursuant to the Agreement following the earlier of (i) the final payment
(or any advance with respect thereto) on or other liquidation of the last
Mortgage Loan or REO Property remaining in the Trust, and (ii) the purchase by
the Depositor, Lehman Brothers Inc., the Master Servicer, the Special Servicer
or any Controlling Class Certificateholder at a price determined as provided in
the Agreement of all Mortgage Loans and any REO Properties remaining in the
Trust. The Agreement permits, but does not require, any Controlling Class
Certificateholder (with priority among such Holders being given to the Holder of
Certificates representing the greatest Percentage Interest in the Controlling
Class), the Special Servicer, the Master Servicer, the Depositor or Lehman
Brothers Inc., in that order of priority (with the Controlling Class
Certificateholder having the most senior priority) to purchase from the Trust
all Mortgage Loans and any REO Properties remaining therein. The exercise of
such right will effect early retirement of the Certificates; however, such right
to purchase is subject to the aggregate Stated Principal Balance of the Mortgage
Pool at the time of purchase being less than 1.0% of the initial aggregate
Certificate Principal Balance of all of the Principal Balance Certificates.

          The Agreement permits, with certain exceptions therein provided, the
amendment thereof, and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and any Fiscal
Agent thereunder and the rights of the Certificateholders thereunder, at any
time by the Depositor, the Master Servicer, the Special Servicer, the Trustee
and any Fiscal Agent with the consent of the Holders of Certificates entitled to
at least 66-2/3% of the Voting Rights allocated to the affected Classes. Any
such consent by the Holder of this Certificate shall be conclusive and binding
on such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain circumstances,
including any amendment necessary to maintain the status of any REMIC Pool as a
REMIC, without the consent of the Holders of any of the Certificates.

          Unless the certificate of authentication hereon has been executed by
the Authenticating Agent, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

          The registered Holder hereof, by its acceptance hereof, agrees that it
will look solely to the Trust (to the extent of its rights therein) for
distributions hereunder.

          This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, without applying any conflicts of law principles of such state
(other than the provisions of Section 5-1401 of the New York General Obligations
Law), and the obligations, rights and remedies of the Holder hereof shall be
determined in accordance with such laws.


                                     A-7-11

Ladies and Gentlemen:

          Pursuant to Section 2.02(b) of the Pooling and Servicing Agreement
dated as of June 12, 2006, relating to the above-referenced Certificates (the
"Agreement"), LaSalle Bank National Association, in its capacity as trustee (the

hereof to the Agreement (except as identified in the exception report attached
hereto) that: (i) all documents specified or referred to in subclause (A) of
Section 2.02(b) are in its possession or the possession of a Custodian on its
behalf; (ii) the recordation/filing contemplated by Section 2.01(c) of the
Agreement (except in the case of an Outside Serviced Trust Mortgage Loan) has
been completed (based solely on receipt by the Trustee or by a Custodian on its
behalf of the particular recorded/filed documents); (iii) all documents received
by it or any Custodian with respect to such Mortgage Loan have been reviewed by
it or by such Custodian on its behalf and (A) appear regular on their face
(handwritten additions, changes or corrections shall not constitute
irregularities if initialed by the Mortgagor), (B) appear to have been executed
(where appropriate) and (C) purport to relate to such Mortgage Loan; and (iv)
based on the examinations referred to in Sections 2.02(a) and 2.02(b) of the
Agreement and in this Certification and only as to the foregoing documents, the
information set forth in the Trust Mortgage Loan Schedule with respect to the
items specified in clauses (v) and (vi)(B) of the definition of "Trust Mortgage
Loan Schedule" accurately reflects the information set forth in the Mortgage
File.

          Neither the Trustee nor any Custodian is under any duty or obligation
to inspect, review or examine any of the documents, instruments, certificates or
other papers relating to the Mortgage Loans delivered to it to determine that
the same are valid, legal, effective, genuine, binding, enforceable, sufficient
or appropriate for the represented purpose or that they are other than what they
purport to be on their face. Furthermore, neither the Trustee nor any Custodian
shall have any responsibility for determining whether the text of any assignment
or endorsement is in proper or recordable form, whether the requisite recording
of any document is in accordance with the requirements of any applicable
jurisdiction, or whether a blanket assignment is permitted in any applicable
jurisdiction. In performing the review contemplated herein, the Trustee or any
Custodian may rely on the Depositor as to the purported genuineness of any such
document and any signature thereon.

Ladies and Gentlemen:

          This letter is delivered to you in connection with the transfer by
_________________________ (the "Transferor") to __________________________ (the
"Transferee") of the captioned Certificates (the "Transferred Certificates"),
pursuant to Section 5.02 of the Pooling and Servicing Agreement (the "Pooling
and Servicing Agreement"), dated as of June 12, 2006, between Structured Asset
Securities Corporation II, as Depositor, Wachovia Bank, National Association, as
Master Servicer, LNR Partners, Inc., as Special Servicer, and LaSalle Bank
National Association, as Trustee. All capitalized terms used herein and not
otherwise defined shall have the respective meanings set forth in the Pooling
and Servicing Agreement. The Transferor hereby certifies, represents and
warrants to you, as Certificate Registrar, and for the benefit of the Trustee
and the Depositor, that:

          1. The Transferor is the lawful owner of the Transferred Certificates
     with the full right to transfer such Certificates free from any and all
     claims and encumbrances whatsoever.

          2. Neither the Transferor nor anyone acting on its behalf has (a)
     offered, transferred, pledged, sold or otherwise disposed of any
     Transferred Certificate, any interest in a Transferred Certificate or any
     other similar security to any person in any manner, (b) solicited any offer
     to buy or accept a transfer, pledge or other disposition of any Transferred
     Certificate, any interest in a Transferred Certificate or any other similar
     security from any person in any manner, (c) otherwise approached or
     negotiated with respect to any Transferred Certificate, any interest in a
     Transferred Certificate or any other similar security with any person in
     any manner, (d) made any general solicitation with respect to any
     Transferred Certificate, any interest in a Transferred Certificate or any
     other similar security by means of general advertising or in any other
     manner, or (e) taken any other action with respect to any Transferred
     Certificate, any interest in a Transferred Certificate or any other similar
     security, which (in the case of any of the acts described in clauses (a)
     through (e) hereof) would constitute a distribution of the Transferred
     Certificates under the Securities Act of 1933, as amended (the "Securities
     Act"), would render the disposition of the Transferred Certificates a
     violation of Section 5 of the Securities Act or any state securities laws,
     or would require


                                     F-1-1



     registration or qualification of the Transferred Certificates pursuant to
     the Securities Act or any state securities laws.

          2. The Transferee has been furnished with all information regarding
     (a) the Depositor, (b) the Transferred Certificates and distributions
     thereon, (c) the nature, performance and servicing

     _____ Broker-dealer. The Transferee is a dealer registered pursuant to
           Section 15 of the Securities Exchange Act of 1934, as amended.

     _____ Insurance Company. The Transferee is an insurance company whose

           registered investment companies should complete Annex 2 rather than

           _____________________________________________________________________
           ____________________________________________________________________.

          3. For purposes of determining the aggregate amount of securities
     owned and/or invested on a discretionary basis by any Person, the
     Transferee did not include (i) securities of issuers that are affiliated
     with such Person, (ii) securities that are part of an unsold allotment to
     or subscription by such Person, if such Person is a dealer, (iii) bank
     deposit notes and certificates of deposit, (iv) loan participations, (v)
     repurchase agreements, (vi) securities owned but subject to a repurchase
     agreement and (vii) currency, interest rate and commodity swaps.

          4. For purposes of determining the aggregate amount of securities
     owned and/or invested on a discretionary basis by any Person, the
     Transferee used the cost of such securities to such Person, unless such
     Person reports its securities holdings in its financial statements on the
     basis of their market value, and no current information with respect to the
     cost of those securities has been published, in which case the securities
     were valued at market. Further, in determining


                                     F-2A-4



     such aggregate amount, the Transferee may have included securities owned by
     subsidiaries of such Person, but only if such subsidiaries are consolidated
     with such Person in its financial statements prepared in accordance with
     generally accepted accounting principles and if the investments of such
     subsidiaries are managed under such Person's direction. However, such
     securities were not included if such Person is a majority-owned,
     consolidated subsidiary of another enterprise and such Person is not itself
     a reporting company under the Securities Exchange Act of 1934, as amended.

          5. The Transferee is familiar with Rule 144A and understands that the
     Transferor and other parties related to the Transferred Certificates are
     relying and will continue to rely on the statements made herein because one
     or more sales to the Transferee may be in reliance on Rule 144A.

           ___   ___   Will the Transferee be purchasing the Transferred
           Yes    No   Certificates only for the Transferee's own account?

          6. If the answer to the foregoing question is "no," then in each case
     where the Transferee is purchasing for an account other than its own, such
     account belongs to a third party that is itself a "qualified institutional
     buyer" within the meaning of Rule 144A, and the "qualified institutional
     buyer" status of such third party has been established by the Transferee
     through one or more of the appropriate methods contemplated by Rule 144A.

          7. The Transferee will notify each of the parties to which this
     certification is made of any changes in the information and conclusions
     herein. Until such notice is given, the Transferee's purchase of the
     Transferred Certificates will constitute a reaffirmation of this
     certification as of the date of such purchase. In addition, if the
     Transferee is a bank or savings and loan as provided above, the Transferee
     agrees that it will furnish to such parties any updated annual financial
     statements that become available on or before the date of such purchase,
     promptly after they become available.

          8. Capitalized terms used but not defined herein have the respective
     meanings ascribed thereto in the Pooling and Servicing Agreement pursuant
     to which the Transferred Certificates were issued.

     a person fulfilling an equivalent function, or other executive officer of
     the entity purchasing the Transferred Certificates (the "Transferee") or,
     if the Transferee is a "qualified institutional buyer" as that term is
     defined in Rule 144A ("Rule 144A") under the Securities Act of 1933, as
     amended, because the Transferee is part of a Family of Investment Companies
     (as defined below), is an executive officer of the investment adviser (the
     "Adviser").

          2. The Transferee is a "qualified institutional buyer" as defined in
     Rule 144A because (i) the Transferee is an investment company registered
     under the Investment Company Act of 1940, and (ii) as marked below, the
     Transferee alone owned and/or invested on a discretionary basis, or the
     Transferee's Family of Investment Companies owned, at least $100,000,000 in
     securities (other than the excluded securities referred to below) as of the
     end of the Transferee's most recent fiscal year. For purposes of
     determining the amount of securities owned by the Transferee or the
     Transferee's Family of Investment Companies, the cost of such securities
     was used, unless the Transferee or any member of the Transferee's Family of
     Investment Companies, as the case may be, reports its securities holdings
     in its financial statements on the basis of their market value, and no
     current information with respect to the cost of those securities has been
     published, in which case the securities of such entity were valued at
     market.

     _____ The Transferee owned and/or invested on a discretionary basis
           $___________________ in securities (other than the excluded
           securities referred to below) as of the end of the Transferee's most
           recent fiscal year (such amount being calculated in accordance with
           Rule 144A).

     _____ The Transferee is part of a Family of Investment Companies which
           owned in the aggregate $______________ in securities (other than the
           excluded securities referred to below) as of the end of the
           Transferee's most recent fiscal year (such amount being calculated in
           accordance with Rule 144A).

          3. The term "Family of Investment Companies" as used herein means two
     or more registered investment companies (or series thereof) that have the
     same investment adviser or investment advisers that are affiliated (by
     virtue of being majority owned subsidiaries of the same parent or because
     one investment adviser is a majority owned subsidiary of the other).

          4. The term "securities" as used herein does not include (i)
     securities of issuers that are affiliated with the Transferee or are part
     of the Transferee's Family of Investment Companies, (ii)


                                     F-2A-6



     bank deposit notes and certificates of deposit, (iii) loan participations,
     (iv) repurchase agreements, (v) securities owned but subject to a
     repurchase agreement and (vi) currency, interest rate and commodity swaps.
     For purposes of determining the aggregate amount of securities owned and/or
     invested on a discretionary basis by the Transferee, or owned by the
     Transferee's Family of Investment Companies, the securities referred to in
     this paragraph were excluded.

          5. The Transferee is familiar with Rule 144A and understands that the
     Transferor and other parties related to the Transferred Certificates are
     relying and will continue to rely on the statements made herein because one
     or more sales to the Transferee will be in reliance on Rule 144A.

           ___   ___   Will the Transferee be purchasing the Transferred
           Yes    No   Certificates only for the Transferee's own account?

          6. If the answer to the foregoing question is "no," then in each case
     where the Transferee is purchasing for an account other than its own, such
     account belongs to a third party that is itself a "qualified institutional
     buyer" within the meaning of Rule 144A, and the "qualified institutional
     buyer" status of such third party has been established by the Transferee
     through one or more of the appropriate methods contemplated by Rule 144A.

          7. The undersigned will notify the parties to which this certification
     is made of any changes in the information and conclusions herein. Until
     such notice, the Transferee's purchase of the Transferred Certificates will
     constitute a reaffirmation of this certification by the undersigned as of
     the date of such purchase.


                                     F-2A-7



          8. Capitalized terms used but not defined herein have the respective
     meanings ascribed thereto in the Pooling and Servicing Agreement pursuant
     to which the Transferred Certificates were issued.

Ladies and Gentlemen:

          This letter is delivered to you in connection with the transfer by
_________________________ (the "Transferor") to_____________________________(the
"Transferee") of the captioned Certificates (the "Transferred Certificates"),
pursuant to Section 5.02 of the Pooling and Servicing Agreement (the "Pooling
and Servicing Agreement"), dated as of June 12, 2006, between Structured Asset
Securities Corporation II, as Depositor, Wachovia Bank, National Association, as
Master Servicer, LNR Partners, Inc., as Special Servicer, and LaSalle Bank
National Association, as Trustee. All capitalized terms used herein and not
otherwise defined shall have the respective meanings set forth in the Pooling
and Servicing Agreement. The Transferee hereby certifies, represents and
warrants to you, as Certificate Registrar, and for the benefit of the Trustee
and the Depositor, that:

          1. The Transferee is acquiring the Transferred Certificates for its
     own account for investment and not with a view to or for sale or transfer
     in connection with any distribution thereof, in whole or in part, in any
     manner which would violate the Securities Act of 1933, as amended (the
     "Securities Act"), or any applicable state securities laws.

          2. The Transferee understands that (a) the Transferred Certificates
     have not been and will not be registered under the Securities Act or
     registered or qualified under any applicable state securities laws, (b)
     none of the Depositor, the Trustee or the Certificate Registrar is
     obligated so to register or qualify the Class of Certificates to which the
     Transferred Certificates belong, and (c) neither a Transferred Certificate
     nor any security issued in exchange therefor or in lieu thereof may be
     resold or transferred unless it is (i) registered pursuant to the
     Securities Act and registered or qualified pursuant to any applicable state
     securities laws or (ii) sold or transferred in transactions which are
     exempt from such registration and qualification and the Certificate
     Registrar has received: (A) a certification from the Certificateholder
     desiring to effect such transfer substantially in the form attached as
     Exhibit F-1 to the Pooling and Servicing Agreement and a certification from
     such Certificateholder's prospective transferee substantially in


                                     F-2B-1



     the form attached either as Exhibit F-2A to the Pooling and Servicing
     Agreement or as Exhibit F-2B to the Pooling and Servicing Agreement; or (B)
     an opinion of counsel satisfactory to the Trustee with respect to, among
     other things, the availability of such exemption from registration under
     the Securities Act, together with copies of the written certification(s)
     from the transferor and/or transferee setting forth the facts surrounding
     the transfer upon which such opinion is based.

          3. The Transferee understands that it may not sell or otherwise
     transfer any Transferred Certificate or interest therein, except in
     compliance with the provisions of Section 5.02 of the Pooling and Servicing
     Agreement, which provisions it has carefully reviewed, and that each
     Transferred Certificate will bear the following legends:

          THIS CERTIFICATE HAS NOT BEEN REGISTERED OR QUALIFIED UNDER THE
          SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT") OR THE
          SECURITIES LAWS OF ANY STATE. ANY RESALE, PLEDGE, TRANSFER OR OTHER
          DISPOSITION OF THIS CERTIFICATE OR ANY INTEREST HEREIN WITHOUT SUCH
          REGISTRATION OR QUALIFICATION MAY BE MADE ONLY IN A TRANSACTION WHICH
          DOES NOT REQUIRE SUCH REGISTRATION OR QUALIFICATION AND WHICH IS IN
          ACCORDANCE WITH THE PROVISIONS OF SECTION 5.02 OF THE POOLING AND
          SERVICING AGREEMENT REFERRED TO HEREIN.

          NO TRANSFER OF THIS CERTIFICATE OR ANY INTEREST HEREIN MAY BE MADE TO
          (A) ANY RETIREMENT PLAN OR OTHER EMPLOYEE BENEFIT PLAN OR ARRANGEMENT
          THAT IS SUBJECT TO THE EMPLOYEE RETIREMENT INCOME SECURITY ACT OF
          1974, AS AMENDED ("ERISA"), OR SECTION 4975 OF THE INTERNAL REVENUE
          CODE OF 1986, AS AMENDED (THE "CODE"), OR (B) ANY PERSON WHO IS
          DIRECTLY OR INDIRECTLY PURCHASING THIS CERTIFICATE OR SUCH INTEREST
          HEREIN ON BEHALF OF, AS NAMED FIDUCIARY OF, AS TRUSTEE OF, OR WITH
          ASSETS OF ANY SUCH RETIREMENT PLAN OR OTHER EMPLOYEE BENEFIT PLAN OR
          ARRANGEMENT, EXCEPT IN ACCORDANCE WITH THE PROVISIONS OF SECTION 5.02
          OF THE POOLING AND SERVICING AGREEMENT REFERRED TO HEREIN.

          4. Neither the Transferee nor anyone acting on its behalf has (a)
     offered, pledged, sold, disposed of or otherwise transferred any
     Transferred Certificate, any interest in any Transferred Certificate or any
     other similar security to any person in any manner, (b) solicited any offer
     to buy or accept a pledge, disposition or other transfer of any Transferred
     Certificate, any interest in any Transferred Certificate or any other
     similar security from any person in any manner, (c) otherwise approached or
     negotiated with respect to any Transferred Certificate, any interest in any
     Transferred Certificate or any other similar security with any person in
     any manner, (d) made any general solicitation with respect to any
     Transferred Certificate, any interest in any Transferred Certificate or any
     other similar security by means of general


                                     F-2B-2



     advertising or in any other manner, or (e) taken any other action with
     respect to any Transferred Certificate, any interest in any Transferred
     Certificate or any other similar security, which (in the case of any of the
     acts described in clauses (a) through (e) above) would constitute a
     distribution of the Transferred Certificates under the Securities Act,
     would render the disposition of the Transferred Certificates a violation of
     Section 5 of the Securities Act or any state securities law or would
     require registration or qualification of the Transferred Certificates
     pursuant thereto. The Transferee will not act, nor has it authorized or
     will it authorize any person to act, in any manner set forth in the
     foregoing sentence with respect to any Transferred Certificate, any
     interest in any Transferred Certificate or any other similar security.

          5. The Transferee has been furnished with all information regarding
     (a) the Depositor, (b) the Transferred Certificates and distributions
     thereon, (c) the Pooling and Servicing Agreement and the Trust Fund created
     pursuant thereto, (d) the nature, performance and servicing of the Mortgage
     Loans, and (e) all related matters, that it has requested.

          6. The Transferee is an "accredited investor" as defined in any of
     paragraphs (1), (2), (3) and (7) of Rule 501(a) under the Securities Act or
     an entity in which all of the equity owners come within such paragraphs.
     The Transferee has such knowledge and experience in financial and business
     matters as to be capable of evaluating the merits and risks of an
     investment in the Transferred Certificates; the Transferee has sought such
     accounting, legal and tax advice as it has considered necessary to make an
     informed investment decision; and the Transferee is able to bear the
     economic risks of such investment and can afford a complete loss of such
     investment.

     cost of those securities has been published, in which case the securities
     were valued at market. Further, in determining such aggregate amount, the

     its financial


                                     F-2C-5



     statements prepared in accordance with generally accepted accounting
     principles and if the investments of such subsidiaries are managed under
     such Person's direction. However, such securities were not included if such
     Person is a majority-owned, consolidated subsidiary of another enterprise
     and such Person is not itself a reporting company under the Securities
     Exchange Act of 1934, as amended.

          5. The Transferee acknowledges that it is familiar with Rule 144A and
     understands that the Transferor and other parties related to the
     Transferred Certificates are relying and will continue to rely on the
     statements made herein because one or more Transfers to the Transferee may
     be in reliance on Rule 144A.

           ___   __   Will the Transferee be acquiring interests in the
           Yes   No   Transferred Certificates only for the Transferee's own
                      account?

          6. If the answer to the foregoing question is "no," then in each case
     where the Transferee is acquiring any interest in the Transferred
     Certificates for an account other than its own, such account belongs to a
     third party that is itself a "qualified institutional buyer" within the
     meaning of Rule 144A, and the "qualified institutional buyer" status of
     such third party has been established by the Transferee through one or more
     of the appropriate methods contemplated by Rule 144A.

          7. The Transferee will notify each of the parties to which this
     certification is made of any changes in the information and conclusions
     herein. Until such notice is given, the Transferee's acquisition of any
     interest in of the Transferred Certificates will constitute a reaffirmation
     of this certification as of the date of such acquisition. In addition, if
     the Transferee is a bank or savings and loan as provided above, the
     Transferee agrees that it will furnish to such parties any updated annual
     financial statements that become available on or before the date of such
     acquisition, promptly after they become available.

          8. Capitalized terms used but not defined herein have the meanings
     ascribed thereto in the Pooling and Servicing Agreement pursuant to which
     the Transferred Certificates were issued.

            QUALIFIED INSTITUTIONAL BUYER STATUS UNDER SEC RULE 144A
           [FOR TRANSFEREES THAT ARE REGISTERED INVESTMENT COMPANIES]

          The undersigned hereby certifies as follows to [name of Transferor]
(the "Transferor") and for the benefit of Structured Asset Securities
Corporation II with respect to the mortgage pass-through certificates being
transferred in book-entry form (the "Transferred Certificates") as described in
the Transferee certificate to which this certification relates and to which this
certification is an Annex:

          1. As indicated below, the undersigned is the chief financial officer,
     a person fulfilling an equivalent function, or other executive officer of
     the entity acquired interests the Transferred Certificates (the
     "Transferee") or, if the Transferee is a "qualified institutional buyer" as
     that term is defined in Rule 144A under the Securities Act of 1933, as
     amended ("Rule 144A"), because the Transferee is part of a Family of
     Investment Companies (as defined below), is an executive officer of the
     investment adviser (the "Adviser").

          2. The Transferee is a "qualified institutional buyer" as defined in
     Rule 144A because (i) the Transferee is an investment company registered
     under the Investment Company Act of 1940, as amended, and (ii) as marked
     below, the Transferee alone owned and/or invested on a discretionary basis,
     or the Transferee's Family of Investment Companies owned, at least
     $100,000,000 in securities (other than the excluded securities referred to
     below) as of the end of the Transferee's most recent fiscal year. For
     purposes of determining the amount of securities owned by the Transferee or
     the Transferee's Family of Investment Companies, the cost of such
     securities was used, unless the Transferee or any member of the
     Transferee's Family of Investment Companies, as the case may be, reports
     its securities holdings in its financial statements on the basis of their
     market value, and no current information with respect to the cost of those
     securities has been published, in which case the securities of such entity
     were valued at market.

     ____  The Transferee owned and/or invested on a discretionary basis
           $___________________ in securities (other than the excluded
           securities referred to below) as of the end of the Transferee's most
           recent fiscal year (such amount being calculated in accordance with
           Rule 144A).

     ____  The Transferee is part of a Family of Investment Companies which
           owned in the aggregate $______________ in securities (other than the
           excluded securities referred to below) as of the end of the
           Transferee's most recent fiscal year (such amount being calculated in
           accordance with Rule 144A).

          3. The term "Family of Investment Companies" as used herein means two
     or more registered investment companies (or series thereof) that have the
     same investment adviser or investment advisers that are affiliated (by
     virtue of being majority owned subsidiaries of the same parent or because
     one investment adviser is a majority owned subsidiary of the other).


                                     F-2C-7



          4. The term "securities" as used herein does not include (i)
     securities of issuers that are affiliated with the Transferee or are part
     of the Transferee's Family of Investment Companies, (ii) bank deposit notes
     and certificates of deposit, (iii) loan participations, (iv) repurchase
     agreements, (v) securities owned but subject to a repurchase agreement and
     (vi) currency, interest rate and commodity swaps. For purposes of
     determining the aggregate amount of securities owned and/or invested on a
     discretionary basis by the Transferee, or owned by the Transferee's Family
     of Investment Companies, the securities referred to in this paragraph were
     excluded.

          5. The Transferee is familiar with Rule 144A and understands that the
     Transferor and other parties related to the Transferred Certificates are
     relying and will continue to rely on the statements made herein because one
     or more Transfers to the Transferee will be in reliance on Rule 144A.

           _____   _____   Will the Transferee be acquiring interests in the
           Yes     No      Transferred Certificates only for the Transferee's
                           own account?

          6. If the answer to the foregoing question is "no," then in each case
     where the Transferee is acquiring any interest in the Transferred
     Certificates for an account other than its own, such account belongs to a
     third party that is itself a "qualified institutional buyer" within the
     meaning of Rule 144A, and the "qualified institutional buyer" status of
     such third party has been established by the Transferee through one or more
     of the appropriate methods contemplated by Rule 144A.

          7. The undersigned will notify the parties to which this certification
     is made of any changes in the information and conclusions herein. Until
     such notice, the Transferee's acquisition of any interest in the
     Transferred Certificates will constitute a reaffirmation of this
     certification by the undersigned as of the date of such acquisition.

     the Transferred Certificates were issued.

Disqualified Organization is any of the following: (i) the United States, (ii)
any state or political subdivision thereof, (iii) any foreign government, (iv)
any international organization, (v) any agency or instrumentality of any of the
foregoing, (vi) any tax-exempt organization (other than a cooperative described

Code, or (viii) any other entity designated as a "disqualified organization" by
relevant legislation amending the REMIC Provisions and in effect at or proposed

not be treated as an instrumentality of the


                                      H-1-1



United States or of any state or political subdivision thereof if all of its

shall have the meanings set forth in Section 7701 of the Code.

          3. The Purchaser acknowledges that Section 860E(e) of the Code would
impose a substantial tax on the transferor or, in certain circumstances, on an

knowledge that the requirements set forth in paragraphs 2 and 7 hereof are not
satisfied, or to any person or entity with respect to which the Purchaser has
not (at the time of such transfer) satisfied the requirements under the Code to
conduct a reasonable investigation of the financial condition of such person or
entity (or its current beneficial owners if such person or entity is classified
as a partnership under the Code).

          5. The Purchaser agrees to such amendments of the Pooling and
Servicing Agreement as may be required to further effectuate the prohibition
against transferring the [Class R-I] [Class R-II] [Class R-III] [Class R-LR]
Certificates to a Disqualified Organization, an agent thereof or a person that
does not satisfy the requirements of paragraph 7.

          6. The Purchaser consents to the designation of the Trustee as the

          Re:  LB-UBS Commercial Mortgage Trust 2006-C4, Commercial Mortgage
               Pass-Through Certificates, Series 2006-C4 (the "Certificates")

Ladies and Gentlemen:

          This letter is delivered to you in connection with the transfer by
_________________ (the "Transferor") to_____________________ _________________
(the "Transferee") of [Class R-I] [Class R-II] [Class R-III] [Class R-LR]
Certificates evidencing a ____% Percentage Interest in such Class (the "Residual
Interest Certificates"). The Certificates, including the Residual Interest
Certificates, were issued pursuant to the Pooling and Servicing Agreement, dated
as of June 12, 2006 (the "Pooling and Servicing Agreement"), between Structured
Asset Securities Corporation II, as depositor, Wachovia Bank, National
Association, as master servicer, LNR Partners, Inc., as special servicer, and
LaSalle Bank National Association, as trustee. All capitalized terms used but
not otherwise defined herein shall have the respective meanings set forth in the
Pooling and Servicing Agreement. The Transferor hereby certifies, represents and
warrants to you, as Certificate Registrar, that:

               1. No purpose of the Transferor relating to the transfer of the
     Residual Interest Certificates by the Transferor to the Transferee is or
     will be to impede the assessment or collection of any tax.

               2. The Transferor understands that the Transferee has delivered
     to you a Transfer Affidavit and Agreement in the form attached to the
     Pooling and Servicing Agreement as Exhibit H-1. The Transferor does not
     know or believe that any representation contained therein is false.

               3. The Transferor has at the time of this transfer conducted a
     reasonable investigation of the financial condition of the Transferee (or
     the beneficial owners of the Transferee if it is classified as a
     partnership under the Internal Revenue Code of 1986, as amended) as
     contemplated by Treasury regulations section 1.860E-1(c)(4)(i) and, as a
     result of that investigation, the Transferor has determined that the
     Transferee has historically paid its debts as they became due and has found
     no significant evidence to indicate that the Transferee will not continue
     to pay its debts as they become due in the future. The Transferor
     understands that the transfer of the Residual Interest Certificates may not
     be respected for United States


                                     H-2-1



     income tax purposes (and the Transferor may continue to be liable for
     United States income taxes associated therewith) unless the Transferor has
     conducted such an investigation.

                                     Very truly yours,

               d. The Master Servicer received an opinion of counsel (from
     counsel approved by Master Servicer in accordance with the Servicing
     Standard) that the defeasance will not result in an Adverse REMIC Event.

               e. The Master Servicer determined that the defeasance collateral
     will be owned by an entity (the "Defeasance Obligor") as to which one of
     the statements checked below is true:

          ____ the related Mortgagor was a Single-Purpose Entity (as defined in
               Standard & Poor's Structured Finance Ratings Real Estate Finance
               Criteria, as amended to the date of the defeasance (the "S&P
               Criteria")) as of the date of the defeasance, and after the
               defeasance owns no assets other than the defeasance collateral
               and real property securing Mortgage Loan included in the pool;

          ____ the related Mortgagor designated a Single-Purpose Entity (as
               defined in the S&P Criteria) to own the defeasance collateral; or


                                       M-3



          ____ the Master Servicer designated a Single-Purpose Entity (as
               defined in the S&P Criteria) established for the benefit of the
               Trust to own the defeasance collateral.

               f. The Master Servicer received a broker or similar confirmation
     of the credit, or the accountant's letter described below contained
     statements that it reviewed a broker or similar confirmation of the credit,

     Criteria) in the name of the Defeasance Obligor, which account is
     maintained as a securities account by the Trustee acting as a securities
     intermediary.

               g. As securities intermediary, the Trustee is obligated to make
     the scheduled payments on the Mortgage Loan from the proceeds of the
     defeasance collateral directly to the Master Servicer's collection account
     in the amounts and on the dates specified in the Mortgage Loan documents
     or, in a partial defeasance, the portion of such scheduled payments
     attributed to the allocated loan amount for the real property defeased,
     increased by any defeasance premium specified in the Mortgage Loan
     documents (the "Scheduled Payments").

               h. The Master Servicer received from the Mortgagor written
     confirmation from a firm of independent certified public accountants, who
     were approved by the Master Servicer in accordance with the Servicing
     Standard, stating that (i) revenues from principal and interest payments
     made on the defeasance collateral (without taking into account any earnings
     on reinvestment of such revenues) will be sufficient to timely pay each of
     the Scheduled Payments after the defeasance including the payment in full
     of the Mortgage Loan (or the allocated portion thereof in connection with a
     partial defeasance) on its Maturity Date (or, in the case of an ARD
     Mortgage Loan, on its Anticipated Repayment Date or on the date when any
     open prepayment period set forth in the related Mortgage Loan documents
     commences), (ii) the revenues received in any month from the defeasance
     collateral will be applied to make Scheduled Payments within four (4)
     months after the date of receipt, and (iii) interest income from the
     defeasance collateral to the Defeasance Obligor in any calendar or fiscal
     year will not exceed such Defeasance Obligor's interest expense for the
     Mortgage Loan (or the allocated portion thereof in a partial defeasance)
     for such year.

               i. The Master Servicer received opinions from counsel, who were
     approved by the Master Servicer in accordance with the Servicing Standard,
     that (i) the agreements executed by the Mortgagor and/or the Defeasance
     Obligor in connection with the defeasance are enforceable against them in
     accordance with their terms, and (ii) the Trustee will have a perfected,
     first priority security interest in the defeasance collateral described
     above.

               j. The agreements executed in connection with the defeasance (i)
     permit reinvestment of proceeds of the defeasance collateral only in
     Permitted Investments (as defined in the S&P Criteria), (ii) permit release
     of surplus defeasance collateral and earnings on reinvestment to the
     Defeasance Obligor or the Mortgagor only after the Mortgage Loan has been
     paid in full, if any such release is permitted, (iii) prohibit any
     subordinate liens against the defeasance collateral, and (iv) provide for
     payment from sources other than the defeasance collateral or other assets
     of the Defeasance Obligor of all fees and expenses of the securities
     intermediary for administering the defeasance and the securities account
     and all fees and expenses of maintaining the existence of the Defeasance
     Obligor.
