         calculated  pursuant to  clauses (i) through  (iii) below,  and the  denominator  of which is the
         product of (a) the  actual  number of days in the related  Accrual  Period and (b) the  aggregate

         equal to the sum of the following components:
         (i)      the  Uncertificated  Pass-Through  Rate for  REMIC II  Regular  Interests  LT1 minus the
                  Marker  Rate,  applied  to a  notional  amount  equal  to the  aggregate  Uncertificated
                  Principal Balance of REMIC II Regular Interest LT1;
         (ii)     the  Uncertificated  Pass-Through  Rate for  REMIC II  Regular  Interest  LT2  minus the
                  Marker  Rate,  applied  to a  notional  amount  equal  to the  Uncertificated  Principal
                  Balance of REMIC II Regular Interest LT2; and
         (iii)    the  Uncertificated  Pass-Through Rate for REMIC II Regular Interest LT4 minus twice the
                  Marker  Rate,  applied  to a  notional  amount  equal  to the  Uncertificated  Principal
                  Balance of REMIC II Regular Interest LT4.
         Accrued  interest on the Class 4-X  Certificates  shall accrue on the basis of a 360-day year and
         the actual number of days in the related  Accrual Period.  Payments from the Interest  Remittance
         Amount or Principal  Remittance  Amount to any Class of Group 4  Certificates in respect of Basis
         Risk  Shortfalls  or to the  Supplemental  Interest  Trust for  payment to the Swap  Counterparty
         shall be deemed to have first been  distributed  from  REMIC III to the holders of the  Class 4-X
         Certificates  in respect of REMIC III  Regular  Interest  4-X-IO and then paid by such holders to
         such Class of  Group 4  Certificates  or the  Supplemental  Interest  Trust,  as applicable.  Any
         amounts  distributed to the holders of the Class 4-A-2  Certificates  by the Trust  Administrator
         from amounts it receives  from the  Supplemental  Interest  Account shall be deemed to have first
         been paid outside of any REMIC to the holders of the Class 4-X  Certificates  in respect of their
         rights with  respect to the  Supplemental  Interest  Trust and then paid  outside of any REMIC by
         such holders to holders of the Class 4-A-2 Certificates.
(25)     The  Class 4-X  Certificates  will be issued in  certificated,  fully-registered  form in minimum
         denominations of 20% of the Percentage Interest therein and increments of 10% in excess thereof.
(26)     The Class P-1  Certificates will not have a Class Principal  Balance. The Class P-1  Certificates
         shall  have  an  initial   notional   balance  of   $170,239,268.81   and  will  be  entitled  to
         distributions  of Assigned  Prepayment  Premiums  collected  with respect to Loan  Group 1,  Loan
         Group 2,  Loan  Group 3  and the  adjustable-rate  mortgage  loans  in Loan  Group 4  only.  Such
         entitlement shall not be an interest in any REMIC created hereunder.
(27)     The  Class P-1  Certificates  will be issued in  certificated,  fully-registered  form in minimum
         denominations of 20% of the Percentage Interest therein and increments of 10% in excess thereof.
(28)     The Class P-2  Certificates will not have a Class Principal  Balance. The Class P-2  Certificates
         shall have an initial  notional balance of  $73,454,982.36  and will be entitled to distributions
         of Assigned  Prepayment  Premiums collected with respect to the fixed-rate mortgage loans in Loan
         Group 4 only.  Such entitlement shall not be an interest in any REMIC created hereunder.
(29)     The  Class P-2  Certificates  will be issued in  certificated,  fully-registered  form in minimum
         denominations of 20% of the Percentage Interest therein and increments of 10% in excess thereof.
(30)     The Class AR Certificates will be issued in minimum Percentage Interests of 20%.

                  For the  avoidance  of doubt,  the Trust  Administrator  shall  account for any interest
amount due to a  Certificateholder  in excess of the interest rate on the REMIC Regular Interest issued by
REMIC III  evidenced by such  Certificate  as part of the payment made to the Class 4-X  Certificates,  to
the extent it is  entitled  to funds  from the REMIC,  and then paid  outside of the REMIC  pursuant  to a
separate contractual right to such Certificateholder.

                  The  foregoing  REMIC  structure  is intended to cause all of the cash from the Mortgage
Loans to flow  through  to  REMIC III  as cash flow on a REMIC  Regular  Interest,  without  creating  any
shortfall—actual  or  potential  (other  than for credit  losses) to any REMIC  Regular  Interest.  To the
extent that the  structure  is believed  to diverge  from such  intention  the Trust  Administrator  shall
resolve  ambiguities  to  accomplish  such result and shall to the extent  necessary  rectify any drafting
errors or seek  clarification to the structure  without  Certificateholder  approval (but with guidance of
counsel) to accomplish such intention.

Distribution  Date by the allocation of Realized Losses and the  distribution of principal,  determined as
follows:

         For purposes of the succeeding  formulas the following  symbols shall have the meanings set forth
below:

         Y1 =     the   Uncertificated   Principal   Balance  of  REMIC II   Regular  Interest  LT1  after
distributions on the prior Distribution Date.

         Y2 =     the   Uncertificated   Principal   Balance  of  REMIC II   Regular  Interest  LT2  after
distributions on the prior Distribution Date.

         Y3 =     the   Uncertificated   Principal   Balance  of  REMIC II   Regular  Interest  LT3  after
distributions on the prior Distribution Date.

         Y4 =     the   Uncertificated   Principal   Balance  of  REMIC II   Regular  Interest  LT4  after
distributions on the prior Distribution Date (note:  Y3 = Y4).

         ΔY1 =    the REMIC II Regular Interest LT1 Principal Reduction Amount.

         ΔY2 =    the REMIC II Regular Interest LT2 Principal Reduction Amount.

         ΔY3 =    the REMIC II Regular Interest LT3 Principal Reduction Amount.

         ΔY4 =    the REMIC II Regular Interest LT4 Principal Reduction Amount.

         P0 =     the aggregate  Uncertificated  Principal Balance of the REMIC II Regular Interests after
distributions and the allocation of Realized Losses on the prior Distribution Date.

         P1 =     the aggregate  Uncertificated  Principal Balance of the REMIC II Regular Interests after
distributions and the allocation of Realized Losses to be made on such Distribution Date.

         ΔP =     P0 - P1 = the  aggregate  of the  REMIC II  Regular  Interests  LT1,  LT2,  LT3  and LT4
Principal Reduction Amounts.

               =  the aggregate of the principal  portions of Realized  Losses to be allocated to, and the
principal  distributions  to be made on, the Group 4  Certificates  on such  Distribution  Date (including
distributions of accrued and unpaid interest on the Class 4-X Certificates for prior Distribution Dates).

         R0 =     the  Net  Funds  Cap  (stated  as  a  monthly  rate)  after  giving  effect  to  amounts
distributed and Realized Losses allocated on the prior Distribution Date.

         R1 =     the Net Funds Cap  (stated  as a monthly  rate)  after  giving  effect to  amounts to be
distributed and Realized Losses to be allocated on such Distribution Date.

         α =      (Y2 +  Y3)/P0.  The  initial  value  of α on the  Closing  Date  for  use  on the  first
Distribution Date shall be 0.0001.

         γ0 =     the  lesser of (A) the sum for all  Classes of LIBOR  Certificates  of the  product  for
each  Class of  (i) the  lesser of  (x) the  monthly  interest  rate for such  Class and (y) the Net Funds
Cap applicable for distributions to be made on such Distribution Date and (ii) the  aggregate  Certificate
Principal  Balance for such Class after  distributions  and the allocation of Realized Losses on the prior
Distribution Date and (B) R0*P0.

         γ1  =    the  lesser of (A) the sum for all  Classes of LIBOR  Certificates  of the  product  for
each  Class of  (i) the  lesser of  (x) the  monthly  interest  rate for such  Class and (y) the Net Funds
Cap applicable  for  distributions  to be made on the  next  succeeding  Distribution  Date  and  (ii) the
aggregate  Certificate  Principal  Balance  for  such  Class after  distributions  and the  allocation  of
Realized Losses to be made on such Distribution Date and (B) R1*P1.

         Then, based on the foregoing definitions:

         ΔY1 =    ΔP - ΔY2 - ΔY3 - ΔY4;

         ΔY2 =    (α/2){( γ0R1 - γ1R0)/R0R1};

         ΔY3 =    αΔP - ΔY2; and

         ΔY4 =    ΔY3.

         if both ΔY2 and ΔY3, as so determined, are non-negative numbers.  Otherwise:

         (1)      If ΔY2, as so determined, is negative, then

         ΔY2 = 0;

         ΔY3 = α{γ1R0P0 - γ0R1P1}/{γ1R0};

         ΔY4 = ΔY3; and

         ΔY1 = ΔP - ΔY2 - ΔY3 - ΔY4.

         (2)      If ΔY3, as so determined, is negative, then

         ΔY3 = 0;

         ΔY2 = α{γ1R0P0 - γ0R1P1}/{2R1R0P1 -  γ1R0};

         ΔY4 = ΔY3; and

         ΔY1 = ΔP - ΔY2 - ΔY3 - ΔY4.

The Principal Reduction Amount ΔY1 shall be allocated to REMIC II Regular Interest LT1.

Principal  Reduction  Amounts,  and (ii) any  Realized  Losses not  allocated  to any of REMIC II  Regular
Interest LT2,  REMIC II Regular  Interest LT3 and REMIC II Regular  Interest LT4  pursuant to the provisos

(ii) state  that the recorded  document has not been  delivered  to such  Custodian  due solely to a delay
caused by the public  recording  office,  and  (iii) state  the amount of time  generally  required by the
applicable recording office to record and return a document submitted for recordation.

                  In the event that in  connection  with any Mortgage Loan the  Depositor  cannot  deliver
(a) for a Mortgage Loan that is not a MERS Mortgage Loan, the original recorded Mortgage,  (b) all interim
recorded  assignments or (c) the lender's title policy  (together with all riders thereto)  satisfying the
requirements  set forth above,  concurrently  with the execution and delivery hereof because such document
or documents  have not been returned from the  applicable  public  recording  office in the case of clause
(a) or  (b) above,  or because the title policy has not been  delivered to the Seller or the  Depositor by
the applicable  title insurer in the case of clause  (c) above,  the Depositor  shall promptly  deliver to
the related  Custodian,  in the case of clause (a) or  (b) above,  such original  Mortgage or such interim
assignment,  as the case may be, with evidence of recording  indicated  thereon upon receipt  thereof from
the public recording  office,  or a copy thereof,  certified,  if appropriate,  by the relevant  recording
office and, in the case of clause  (c) above,  any title  policy upon receipt  from the  applicable  title
insurer.

                  As promptly as  practicable  subsequent  to such  transfer  and  assignment,  and in any
event, within thirty (30) days thereafter,  DLJMC shall, at its expense,  (i) affix or cause to be affixed
the Trustee's name to each  Assignment of Mortgage,  as the assignee  thereof,  (ii) cause such assignment
to be in proper form for  recording in the  appropriate  public office for real  property  records  within
thirty (30) days after receipt  thereof and  (iii) cause to be delivered for recording in the  appropriate
public  office for real property  records the  assignments  of the Mortgages to the Trustee,  except that,
with respect to any assignment of a Mortgage as to which DLJMC has not received the  information  required
to prepare such  assignment in recordable  form,  DLJMC's  obligation to do so and to deliver the same for
such recording shall be as soon as practicable  after receipt of such  information and in any event within
thirty (30) days after the receipt  thereof,  and DLJMC need not cause to be recorded any assignment which
relates to a Mortgage  Loan in any  jurisdiction  under the laws of which,  as  evidenced by an Opinion of
Counsel delivered by the Depositor (at the Depositor's  expense) to the Trustee,  the Trust  Administrator
and DLJMC,  acceptable to the Rating  Agencies,  the  recordation  of such  assignment is not necessary to
protect the Trustee's and the Certificateholders' interest in the related Mortgage Loan.

                  If  any  original  Mortgage  Note  referred  to in  Section 2.01(b)(i) above  cannot  be
located,  the  obligations of the Depositor to deliver such documents shall be deemed to be satisfied upon
delivery to the related  Custodian of a photocopy of such Mortgage  Note,  if available,  with a lost note
affidavit  and  indemnity.  If any of the  original  Mortgage  Notes for which a lost note  affidavit  and
indemnity was delivered to the Custodian is  subsequently  located,  such original  Mortgage Note shall be
delivered to such Custodian within three (3) Business Days.

(c)      The  Trustee  and the Trust  Administrator  are  authorized  to enter into one or more  Custodial
Agreements,  at the direction of the Depositor,  for the purpose of having a Custodian maintain custody of
the documents and instruments  referred to in this Section 2.01,  and any documents  delivered  thereunder
shall be delivered to such Custodian and any Officer's  Certificates  delivered with respect thereto shall
be delivered to the Trustee, the Trust Administrator and such Custodian.

(d)      It is the express  intent of the parties to this  Agreement  that the  conveyance of the Mortgage
Loans by the  Depositor to the Trustee as provided in this  Section 2.01  be, and be construed  as, a sale
of the Mortgage Loans by the Depositor to the Trustee.  It is,  further,  not the intention of the parties
to this  Agreement  that such  conveyance be deemed a pledge of the Mortgage Loans by the Depositor to the
Trustee  to  secure  a  debt  or  other  obligation  of  the  Depositor.   However,  in  the  event  that,
notwithstanding  the  intent of the  parties  to this  Agreement,  the  Mortgage  Loans are held to be the
property of the  Depositor,  or if any for any other  reason this  Agreement is held or deemed to create a
security  interest in the Mortgage  Loans then  (a) this  Agreement  shall also be deemed to be a security
agreement  within  the  meaning of  Articles  8 and 9 of the New York  Uniform  Commercial  Code;  (b) the
conveyance  provided  for in this  Section 2.01  shall be  deemed  to be a grant by the  Depositor  to the
Trustee  for the  benefit of the  Certificateholders  of a  security  interest  in all of the  Depositor's
right,  title and  interest  in and to (1) the  Mortgage  Loans  listed  in the  Mortgage  Loan  Schedule,
including  all interest and  principal  received or  receivable by the Depositor on or with respect to the
Mortgage Loans after the Cut-off Date and any Assigned Prepayment  Premiums with respect thereto,  but not
including  payments of  principal  and  interest  due and payable on the  Mortgage  Loans on or before the
Cut-off Date, together with the Mortgage Files relating to the Mortgage Loans,  (2) REO Property,  (3) the
Collection  Account,  the Certificate  Account,  the Group 4 Interest Rate Cap Accounts,  the Supplemental
Interest  Account  and all  amounts  deposited  therein  pursuant  to the  applicable  provisions  of this
Agreement,  (4) any  insurance  policies with respect to the Mortgage Loans,  (5) the  Depositor's  rights
under the  Assignment  and  Assumption  Agreement,  (6) the Trust's rights under the Group 4 Interest Rate
Cap Agreements and the Swap Agreement,  and (7) all proceeds of the conversion,  voluntary or involuntary,
of any of the  foregoing  into cash or other liquid  property;  (c) the  possession  by the Trustee or any
Custodian of such items of property  and such other items of property as  constitute  instruments,  money,
negotiable  documents  or chattel  paper shall be deemed to be "in  possession  by the secured  party" for
purposes  of  perfecting  the  security  interest  pursuant  to  Section 9-313  of the  New  York  Uniform
Commercial Code; and  (d) notifications to persons holding such property,  and  acknowledgments,  receipts
or   confirmations   from  persons  holding  such  property,   shall  be  deemed   notifications   to,  or
acknowledgments,  receipts  or  confirmations  from,  financial  intermediaries,  bailees  or  agents  (as
applicable) of the Trustee for the benefit of the  Certificateholders  for the purpose of perfecting  such
security  interest under  applicable law (except that nothing in this clause (d) shall cause any person to
be deemed to be an agent of the  Trustee  for any  purpose  other  than for  perfection  of such  security
interests  unless,  and then only to the extent,  expressly  appointed  and  authorized  by the Trustee in
writing).  The  Depositor  and the Trustee,  upon  directions  from the  Depositor,  shall,  to the extent
consistent  with this  Agreement,  take such actions as may be necessary to ensure that, if this Agreement
were deemed to create a security  interest in the Mortgage Loans,  such security  interest would be deemed
to be a perfected  security  interest of first  priority  under  applicable  law and will be maintained as
such throughout the term of this Agreement.

(e)      The Depositor  hereby  authorizes and directs the Trust  Administrator to (i) execute the Group 4
Interest  Rate Cap  Agreements  and (ii) to  ratify,  on behalf of the Trust,  the terms  agreed to by the
Depositor with respect to the Group 4  Interest Rate Cap  Agreements.  The Depositor shall pay or cause to
be paid on behalf of the Trust the payments owed to the Group 4  Interest Rate Cap  Counterparty as of the
Closing Date pursuant to the terms of the Group 4 Interest Rate Cap Agreements.

(f)      Except as  specifically  set forth in this Agreement or by separate  written  agreement among the
related parties hereto,  the Depositor,  the Seller,  each Servicer and the Master Servicer agree that the
provisions  of this  Agreement  shall  supersede  any  provisions  in any existing  mortgage loan purchase
agreement or servicing  agreement with respect to the Mortgage Loans for which the Depositor,  the Seller,
a Servicer or the Master Servicer may be a party.

SECTION 2.02.     Acceptance by the Trustee.

(a)      Pursuant to the related  Custodial  Agreement,  each  Custodian  agrees to execute and deliver on
the Closing Date to the  Depositor,  the Trustee and the Trust  Administrator  a Trust Receipt and Initial
Certification  in the form annexed hereto as Exhibit I. Based on its review and  examination,  and only as
to the documents identified in such Trust Receipt and Initial  Certification,  each Custodian acknowledges
that such documents  appear  regular on their face and relate to such Mortgage Loan. The Custodians  shall
be under no duty or obligation to inspect,  review or examine said  documents,  instruments,  certificates
or other papers to determine that the same are genuine,  enforceable or  appropriate  for the  represented
purpose or that they have actually  been  recorded in the real estate  records or that they are other than
what they purport to be on their face.

                  Pursuant to the related  Custodial  Agreement,  not later than 90 days after the Closing
Date,  each Custodian  shall deliver to the  Depositor,  the Trustee and the Trust  Administrator  a Trust
Receipt and Final  Certification  in the form annexed hereto as Exhibit J, with any applicable  exceptions
noted thereon.

                  Based  solely  upon the  Trust  Receipt  and  Initial  Certification  received  from the
Custodians,  and subject to the  provisions  of  Section 2.01  and any  exceptions  noted on an  exception
report described in the next paragraph below, the Trustee  acknowledges  receipt of the documents referred
to in  Section 2.01  above  and  declares  that it holds  and  shall  hold  such  documents  and the other
documents  delivered  to it  constituting  the  Mortgage  File,  and that it holds or shall  hold all such
assets and such other assets  included in the  definition of the Trust Fund in trust for the exclusive use
and benefit of all present and future Certificateholders.

                  If, in the course of such review,  a Custodian  finds any document  constituting  a part
of a Mortgage File which does not meet the  requirements of  Section 2.01,  such Custodian shall list such
as an  exception  in  the  Trust  Receipt  and  Final  Certification  pursuant  to the  related  Custodial
Agreement;  provided,  however,  that a Custodian shall not make any  determination  as to whether (i) any
endorsement  is  sufficient  to  transfer  all right,  title and  interest of the party so  endorsing,  as
noteholder  or assignee  thereof,  in and to that  Mortgage  Note or (ii) any  assignment is in recordable
form or is  sufficient  to effect  the  assignment  of and  transfer  to the  assignee  thereof  under the
mortgage to which the assignment relates.

                  The Seller shall  promptly  correct or cure such defect  within 90 days from the date it
was so notified  of such  defect  and,  if the Seller  does not  correct or cure such  defect  within such
period and such defect  materially  and  adversely  affects the  interests  of  Certificateholders  in the
related  Mortgage Loan, the Seller shall either  (a) substitute  for the related Mortgage Loan a Qualified
Substitute  Mortgage  Loan,  which  substitution  shall be  accomplished  in the manner and subject to the
conditions set forth in Section 2.03,  or  (b) repurchase  such Mortgage Loan within 90 days from the date
that the Seller was notified of such defect in writing at the Purchase  Price of such  Mortgage  Loan;  or
such longer  period not to exceed 720 days from the Closing Date if the  substitution  or  repurchase of a
Mortgage  Loan  pursuant to this  provision is required by reason of a delay in delivery of any  documents
by the appropriate  recording office or title insurer, as applicable;  provided,  however, that the Seller
shall have no  liability  for  recording  any  Assignment  of  Mortgage in favor of the Trustee or for the
Custodian's  failure to record such Assignment of Mortgage,  and provided,  further,  that no Seller shall
be  obligated  to  repurchase  or cure any Mortgage  Loan solely as a result of a  Custodian's  failure to
record  such  Assignment  of  Mortgage.  The Trust  Administrator  shall  deliver  or direct  the  related
Custodian  to deliver  to each  Rating  Agency  written  notice  within  270 days  from the  Closing  Date
indicating  each Mortgage Loan (a) for which a mortgage or assignment of mortgage  required to be recorded
hereunder  has not been  returned  by the  appropriate  recording  office or  (b) as  to which  there is a
dispute as to location or status of such  Mortgage  Loan.  Such notice  shall be  delivered  every 90 days
thereafter until the related  Mortgage Loan is returned to the related  Custodian.  Any such  substitution
pursuant  to clause  (a) of the  preceding  sentence  shall not be effected  prior to the  delivery to the
Trustee and the Trust  Administrator  of (1) the Opinion of Counsel required by Section 2.05  hereof,  and
(2) a  Request for Release  substantially  in the form of  Exhibit K.  No substitution  is permitted to be
made in any calendar month after the  Determination  Date for such month.  The Purchase Price for any such
Mortgage  Loan shall be  deposited  by the Seller in the related  Collection  Account and the Seller shall
notify the related  Servicer to deliver a Request for Release  substantially  in the form of  Exhibit K on
or prior to the Business Day  immediately  preceding  such  Distribution  Date in the month  following the
month during which the Seller became  obligated  hereunder to  repurchase  or replace such Mortgage  Loan.
Upon  receipt of notice  from the  Seller,  the  related  Servicer  shall  deliver a Request  for  Release
substantially  in  the  form  of  Exhibit  K  to  the  related  Custodian,   the  Trustee  and  the  Trust
Administrator.  Upon receipt of such  deposit and Request for Release with respect  thereto in the form of
Exhibit K,  the related  Custodian shall release the related Mortgage File to the Seller and shall execute
and deliver at such entity's request such  instruments of transfer or assignment  prepared by such entity,
in each  case  without  recourse,  as  shall be  necessary  to vest in such  entity,  or a  designee,  the
Trustee's interest in any Mortgage Loan released pursuant hereto.

                  If pursuant to the preceding  paragraph  the Seller  repurchases a Mortgage Loan that is
a MERS Mortgage  Loan, the related  Servicer  shall,  at the Seller's  expense,  either  (i) cause MERS to
execute and deliver an  Assignment  of Mortgage in  recordable  form to transfer the Mortgage from MERS to
the  Seller  and shall  cause  such  Mortgage  to be  removed  from  registration  on the MERS®  System in
accordance  with MERS' rules and  regulations  or  (ii) cause  MERS to  designate  on the MERS® System the
Seller as the beneficial holder of such Mortgage Loan.

(b)      It is  understood  and agreed that the  obligation  of the Seller to cure,  substitute  for or to
repurchase any Mortgage Loan which does not meet the  requirements  of Section 2.01  shall  constitute the
sole remedy respecting such defect available to the Trustee,  the Trust  Administrator,  the Depositor and
any Certificateholder against the Seller.

(c)      With  respect  to  any  Mortgage   Loan  which  the  Seller   reasonably   believes   breaches  a
representation,  warranty or covenant  under the mortgage  loan purchase  agreement  pursuant to which the
Seller  purchased  from the  originator or prior holder of such Mortgage  Loan,  the Seller shall have the
right to  repurchase  such  Mortgage  Loan from the Trust at any time in order to  facilitate  its  rights
against such  originator or prior holder of such Mortgage Loan at a price equal to the  Repurchase  Price;
provided,  however,  that in no event shall such  repurchase  take place with  respect to  Mortgage  Loans
constituting more than 5% of the aggregate Cut-off Date Principal Balance of the Mortgage Loans.

                  In the event that DLJMC  exercises such option,  the Repurchase  Price therefor shall be
deposited  in the  Certificate  Account and DLJMC shall  notify the related  Servicer to deliver a Request
for Release  substantially in the form of Exhibit K.  Upon receipt of notice from the Seller,  the related
Servicer  shall  deliver a Request  for  Release  substantially  in the form of  Exhibit K to the  related
Custodian,  the  Trustee  and the Trust  Administrator.  Upon such  deposit  of the  Repurchase  Price and
receipt of a Request  for  Release  in the form of Exhibit K, the  related  Custodian  shall  release  the
related  Mortgage  File held for the benefit of the  Certificateholders  to DLJMC,  and the Trustee  shall
execute and deliver at DLJMC's  direction such  instruments  of transfer or assignment  prepared by DLJMC,
in each case without recourse, as shall be necessary to transfer title from the Trustee to DLJMC.

SECTION 2.03.     Representations and Warranties of the Seller, Master Servicer and Servicers.

(a)      Each of DLJMC, in its capacity as Seller,  Wells Fargo, in its capacity as Master Servicer,  SPS,
in its  capacity  as Servicer  and Special  Servicer,  Wells  Fargo,  in its  capacity  as  Servicer,  and
GreenPoint  in its capacity as Servicer,  hereby makes the  representations  and  warranties  set forth in
Schedules IIA, IIB, IIC, IID or IIE hereto,  respectively,  and by this reference  incorporated herein, to
the  Depositor,  the  Trustee and the Trust  Administrator,  as of the Closing  Date,  or if so  specified
therein,  as of the  Cut-off  Date or such  other  date as may be  specified.  In  addition,  SPS,  in its
capacity as Servicer and Special Servicer,  Wells Fargo, in its capacity as Servicer,  and GreenPoint,  in
its capacity as Servicer,  makes the  representations  and  warranties set forth in Schedules IIC, IID and
IIE hereto,  respectively,  and by this reference  incorporated  herein,  to the Master Servicer as of the
Closing Date, or if so specified therein, as of the Cut-off Date or such other date as may be specified.

(b)      DLJMC, in its capacity as Seller,  hereby makes the  representations  and warranties set forth in
Schedule III as to the Mortgage Loans and by this reference  incorporated  herein,  to the Depositor,  the
Trustee and the Trust  Administrator,  as of the  Closing  Date,  or if so  specified  therein,  as of the
Cut-off Date or such other date as may be specified.

(c)      Upon  discovery by any of the parties  hereto of a breach of a  representation  or warranty  made
pursuant   to   Section 2.03(b) that   materially   and   adversely   affects   the   interests   of   the
Certificateholders  in any Mortgage  Loan,  the party  discovering  such breach  shall give prompt  notice
thereof to the other  parties.  The Seller  hereby  covenants  that  within 90 days of the  earlier of its
discovery or its receipt of written  notice from any party of a breach of any  representation  or warranty
made by it pursuant to  Section 2.03(b) which  materially  and  adversely  affects  the  interests  of the
Certificateholders  in any  Mortgage  Loan sold by the Seller to the Trust,  it shall cure such  breach in
all  material  respects,  and if such breach is not so cured,  shall,  (i) if  such 90 day period  expires
prior to the second  anniversary  of the Closing  Date,  remove such  Mortgage  Loan (a "Deleted  Mortgage
Loan")  from the Trust Fund and  substitute  in its place a Qualified  Substitute  Mortgage  Loan,  in the
manner and subject to the  conditions  set forth in this  Section 2.03;  or  (ii) repurchase  the affected
Mortgage Loan or Mortgage  Loans at the Purchase Price in the manner set forth below;  provided,  however,
that any such  substitution  pursuant  to  (i) above  shall not be effected  prior to the  delivery to the
Trustee and the Trust  Administrator  of the Opinion of Counsel required by Section 2.05  hereof,  if any,
and any such  substitution  pursuant to (i) above  shall not be effected prior to the additional  delivery
to the Trustee,  the Trust Administrator and the related Custodian of a Request for Release  substantially
in the  form of  Exhibit K  relating  to the  Deleted  Mortgage  Loan and the  Mortgage  File for any such
Qualified  Substitute  Mortgage  Loan.  The  Seller  shall  promptly  reimburse  the  Trustee,  the  Trust
Administrator,  the Special  Servicer and the related Servicer (if such Servicer is not the Seller of such
Mortgage  Loan) for any  actual out of pocket  expenses  reasonably  incurred  by the  Trustee,  the Trust
Administrator,  the Special  Servicer and the related Servicer (if such Servicer is not the Seller of such
Mortgage  Loan) in respect of enforcing the remedies for such breach.  With respect to any  representation
and warranties described in this  Section 2.03 which  are made to the best of the Seller's knowledge if it
is  discovered  by any of the  Depositor,  the Master  Servicer,  the Seller,  any  Servicer,  the Special
Servicer,  the Trustee or the Trust  Administrator that the substance of such  representation and warranty
is inaccurate  and such  inaccuracy  materially  and adversely  affects the value of the related  Mortgage
Loan or the interests of the  Certificateholders  therein,  notwithstanding the Seller's lack of knowledge
with  respect to the  substance of such  representation  or warranty,  such  inaccuracy  shall be deemed a
breach of the applicable representation or warranty.

                  With  respect to any  Qualified  Substitute  Mortgage  Loan or Loans,  the Seller  shall
deliver to the  related  Custodian  for the  benefit of the  Certificateholders  the  Mortgage  Note,  the
Mortgage,  the  related  assignment  of the  Mortgage,  and such other  documents  and  agreements  as are
required by  Section 2.01(b),  with the Mortgage  Note  endorsed and the Mortgage  assigned as required by
Section 2.01.  No  substitution  is  permitted to be made in any  calendar  month after the  Determination
Date for such month.  Scheduled  Payments due with respect to Qualified  Substitute  Mortgage Loans in the
month of  substitution  shall not be part of the Trust  Fund and shall be  retained  by the  Seller on the
next succeeding  Distribution  Date. For the month of substitution,  distributions  to  Certificateholders
will  include the  monthly  payment due on any Deleted  Mortgage  Loan for such month and  thereafter  the
Seller shall be entitled to retain all amounts  received in respect of such  Deleted  Mortgage  Loan.  The
Seller shall amend the Mortgage Loan  Schedule for  the benefit of the  Certificateholders  to reflect the
removal of such Deleted  Mortgage Loan and the substitution of the Qualified  Substitute  Mortgage Loan or
Loans and the Seller shall deliver the amended  Mortgage Loan  Schedule to the Trustee,  the Servicers and
the Trust  Administrator.  Upon such substitution,  the Qualified  Substitute Mortgage Loan or Loans shall
be subject to the terms of this  Agreement  in all  respects,  and the Seller shall be deemed to have made
with respect to such Qualified  Substitute  Mortgage Loan or Loans,  as of the date of  substitution,  the
representations  and  warranties  made pursuant to  Section 2.03(b) with  respect to such  Mortgage  Loan.
Upon any such  substitution  and the  deposit  to the  Collection  Account of the  amount  required  to be
deposited  therein in  connection  with such  substitution  as described in the following  paragraph,  the
Trustee  shall  instruct the related  Custodian  to release the Mortgage  File held for the benefit of the
Certificateholders  relating to such Deleted  Mortgage  Loan to the Seller and the Trustee  shall  execute
and deliver at the Seller's  direction such instruments of transfer or assignment  prepared by the Seller,
in each case without  recourse,  as shall be necessary to vest title in the Seller,  or its designee,  the
Trustee's interest in any Deleted Mortgage Loan substituted for pursuant to this Section 2.03.

                  For  any  month  in  which  the  Seller  substitutes  one or more  Qualified  Substitute
Mortgage Loans for one or more Deleted  Mortgage  Loans,  the Master  Servicer shall  determine the amount
(if any) by which the aggregate  principal balance of all such Qualified  Substitute  Mortgage Loans as of
the  date of  substitution  is less  than the  aggregate  Stated  Principal  Balance  of all such  Deleted
Mortgage Loans (after  application of the scheduled  principal  portion of the monthly payments due in the
month of  substitution).  The amount of such  shortage  (the  "Substitution  Adjustment  Amount")  plus an
amount equal to the aggregate of any unreimbursed  Advances,  Servicing Advances and unpaid Servicing Fees
with respect to such Deleted  Mortgage Loans shall be deposited in the related  Collection  Account by the
Seller and the Seller  shall  notify the related  Servicer to deliver a Request for Release  substantially
in the form of Exhibit K on or before the Business Day  immediately  preceding  the  Distribution  Date in
the month  succeeding  the calendar  month during which the related  Mortgage  Loan became  required to be
repurchased  or replaced  hereunder.  Upon receipt of notice from the Seller,  the related  Servicer shall
deliver a Request  for  Release  substantially  in the form of  Exhibit K to the  related  Custodian,  the
Trustee and the Trust Administrator.
                  One or more mortgage loans may be substituted  for one or more Deleted  Mortgage  Loans.
The determination of whether a mortgage loan is a Qualified  Substitute  Mortgage Loan may be satisfied on
an individual  basis.  Alternatively,  if more than one mortgage loan is to be substituted for one or more
Deleted  Mortgage Loans,  the  characteristics  of such mortgage loans and Deleted Mortgage Loans shall be
aggregated  or  calculated  on a weighted  average  basis,  as  applicable,  in  determining  whether such
mortgage loans are Qualified Substitute Mortgage Loans.

                  In the event that the Seller shall be required to  repurchase a Mortgage  Loan  pursuant
to this Agreement,  the Purchase Price therefor shall be deposited in the related  Collection  Account and
the Seller shall notify the related  Servicer to deliver a Request for Release  substantially  in the form
of Exhibit K  on or before the  Business Day  immediately  preceding  the  Distribution  Date in the month
following  the month during which the Seller  became  obligated  hereunder to  repurchase  or replace such
Mortgage Loan.  Upon receipt of notice from the Seller,  the related  Servicer shall deliver a Request for
Release  substantially  in the form of  Exhibit K to the  related  Custodian,  the  Trustee  and the Trust
Administrator.   Upon  such  deposit  of  the  Purchase  Price  and  receipt  of  a  Request  for  Release
substantially  in the form of Exhibit K,  the related  Custodian  shall release the related  Mortgage File
held for the benefit of the  Certificateholders  to such Person, and the Trustee shall execute and deliver
at such Person's  direction such  instruments of transfer or assignment  prepared by such Person,  in each
case without  recourse,  as shall be necessary to transfer  title from the Trustee.  It is understood  and
agreed that the  obligation  under this  Agreement of any Person to cure,  repurchase  or  substitute  any
Mortgage  Loan as to which a breach has  occurred  and is  continuing  shall  constitute  the sole  remedy
against such Persons respecting such breach available to  Certificateholders,  the Depositor,  the Trustee
or the Trust Administrator on their behalf.

                  The  representations  and warranties  made pursuant to this  Section 2.03  shall survive
delivery of the respective  Mortgage Files to the Trustee,  the Trust  Administrator or the Custodians for
the benefit of the Certificateholders.

                  Notwithstanding  the foregoing,  the  substitution of a Deleted  Mortgage Loan that is a
GreenPoint  Serviced  Mortgage Loan or the  repurchase  of a Mortgage  Loan that is a GreenPoint  Serviced
Mortgage  Loan by the Seller  shall be  subject  to, and shall in no way  adversely  affect,  the right of
GreenPoint to continue  servicing  and  collecting  its  Servicing  Fee for such Deleted  Mortgage Loan or
Mortgage Loan, as applicable.

SECTION 2.04.     Representations and Warranties of the Depositor as to the Mortgage Loans.

                  The  Depositor  hereby  represents  and  warrants  to the  Trustee  with  respect to the
Mortgage Loans that, as of the Closing Date,  assuming good title has been conveyed to the Depositor,  the
Depositor  had good title to the  Mortgage  Loans and  Mortgage  Notes,  and did not encumber the Mortgage
Loans during its period of ownership thereof, other than as contemplated by the Agreement.

                  It is understood  and agreed that the  representations  and warranties set forth in this
Section 2.04 shall survive delivery of the Mortgage Files to the related Custodian.

SECTION 2.05.     Delivery of Opinion of Counsel in Connection with Substitutions.

                  Notwithstanding  any contrary provision of this Agreement,  no substitution  pursuant to
Section 2.02  shall be made more than ninety (90) days after the Closing  Date unless the Seller  delivers
to the Trustee and the Trust  Administrator  an Opinion of Counsel,  which Opinion of Counsel shall not be
at the  expense  of any of the  Trustee,  the Trust  Administrator  or the Trust  Fund,  addressed  to the
Trustee and the Trust  Administrator,  to the effect that such  substitution  will not  (i) result  in the
imposition of the tax on "prohibited  transactions" on the Trust Fund or  contributions  after the Startup
Date, as defined in Sections  860F(a)(2) and 860G(d) of  the Code,  respectively,  or (ii) cause any REMIC
created  hereunder  to fail to  qualify  as a REMIC at any time  that any  Certificates  are  outstanding;
provided,  however,  that no Opinion of Counsel  shall be required if (A) the  substitution  occurs within
two years of the Closing  Date and (B) the  substitution  occurs with  respect to Mortgage  Loans that are
"defective"  under  the Code and the  Seller  delivers  to the  Trustee  and the  Trust  Administrator  an
Officer's Certificate substantially in the form of Exhibit Z.

SECTION 2.06.     Issuance of Certificates.

                  The Trustee  acknowledges  the  assignment to it of the Mortgage Loans together with the
assignment  to it of all other  assets  included  in the Trust  Fund,  receipt  of which,  subject  to the
provisions of  Section 2.02(a),  is hereby  acknowledged.  Concurrently  with such assignment and delivery
and in exchange  therefor,  the Trust  Administrator,  pursuant to the  written  request of the  Depositor
executed  by  an  officer  of  the  Depositor,  has  executed  the  Certificates  and  caused  them  to be
authenticated  and  delivered to or upon the order of the  Depositor  in  authorized  denominations  which
evidence  ownership  of the Trust  Fund.  The  rights  of the  Holders  of such  Certificates  to  receive
distributions  from the Trust Fund and all ownership  interests of the Holders of the Certificates in such
distributions shall be as set forth in this Agreement.

SECTION 2.07.     REMIC Provisions.

(a)      The  Depositor  hereby  elects and  authorizes  the Trust  Administrator  to treat the Trust Fund
(exclusive of any entitlement to Assigned Prepayment  Premiums,  the Group 4 Interest Rate Cap Agreements,
the assets held in the Group 4  Interest Rate Cap Accounts,  and rights to payments from the  Supplemental
Interest  Account) as the number of separate  REMICs  specified  in the  Preliminary  Statement  (each,  a
"REMIC")  under the Code and,  if  necessary,  under  applicable  state  law and  apply  such  Preliminary
Statement in determining  the rights of the Interests in REMICs thereby  created.  Each such election will
be made on Form 1066 or other appropriate  federal tax or information  return (including Form 8811) or any
appropriate  state return  (x) for the taxable  year ending on the last day of the calendar  year in which
the  Certificates  are issued and (y) for the taxable year ending on the last day of the calendar  year in
which  Certificates  are  first  sold to a third  party.  The  Closing  Date is hereby  designated  as the
"startup day" of each REMIC created  hereunder within the meaning of  Section 860G(a)(9)  of the Code. The
"regular  interests"  (within the meaning of  Section 860G of the Code) in each REMIC shall consist of the
regular  interests with the terms set forth for each REMIC in the  Preliminary  Statement and the Class AR
and Class AR-L  Certificates shall represent the beneficial  ownership of the "residual  interest" in each
REMIC created  hereunder.  Neither the Depositor nor the Trust  Administrator nor the Trustee shall permit
the creation of any  "interests"  (within the meaning of Section 860G of the Code) in any REMIC other than
as set forth in the Preliminary Statement.

(b)      The Trust  Administrator  shall act as the "tax matters  person" (within the meaning of the REMIC
Provisions) for each REMIC created hereunder,  in the manner provided under Treasury  regulations  section
1.860F  4(d) and  temporary  Treasury  regulations  section  301.6231(a)(7)1T.  In the event  that for any
reason, the Trust  Administrator is not recognized as the tax matters person then the Trust  Administrator
shall act as agent for the Class AR and the Class AR-L  Certificateholder  as tax matters  person.  By its
acceptance  of a Residual  Certificate,  each Holder  thereof  shall have agreed to such  appointment  and
shall have consented to the appointment of the Trust  Administrator  as its agent to act on behalf of each
REMIC created hereunder pursuant to the specific duties outlined herein.

(c)      A Holder of a Residual  Certificate,  by the  purchase  of such  Certificate,  shall be deemed to
have agreed to timely pay, upon demand by the Trust  Administrator,  the amount of any minimum  California
state  franchise  taxes  due  with  respect  to  the  related  REMIC  created   hereunder  under  Sections
23151(a) and  23153(a) of the California  Revenue and Taxation Code.  Notwithstanding  the foregoing,  the
Trust  Administrator  shall be  authorized  to  retain  the  amount  of such tax  from  amounts  otherwise
distributable  to such Holder in the event such Holder  does not  promptly  pay such amount upon demand by
the Trust  Administrator.  In the event that any other federal,  state or local tax is imposed,  including
without  limitation  taxes imposed on a "prohibited  transaction" of a REMIC as defined in Section 860F of
the  Code,  such tax  shall be  charged  against  amounts  otherwise  available  for  distribution  to the
applicable  Holder  of  a  Residual   Certificate  and  then  against  amounts  otherwise   available  for
distribution  to the  Holders of Regular  Certificates  in  accordance  with the  provisions  set forth in
Section 4.01.  The Trust  Administrator or the Trustee shall promptly  deposit in the Certificate  Account
any amount of  "prohibited  transaction"  tax that results from a breach of the Trust  Administrator's  or
the Trustee's  duties,  respectively,  under this Agreement.  The Master Servicer or the related  Servicer
shall  promptly  deposit in the  Certificate  Account  any  amount of  "prohibited  transaction"  tax that
results  from a breach of the  Master  Servicer's  or such  Servicer's  duties,  respectively,  under this
Agreement.

(d)      The Trust  Administrator  shall act as  attorney  in fact and as the tax  matters  person of each
REMIC created hereunder and in such capacity the Trust Administrator  shall:  (i) prepare,  sign and file,
or cause to be  prepared,  signed and filed,  federal and state tax returns  using a calendar  year as the
taxable  year for each REMIC  created  hereunder  when and as required by the REMIC  Provisions  and other
applicable  federal  income tax laws as the direct  representative  of each such REMIC in compliance  with
the Code and shall  provide  copies of such returns as required by the Code;  (ii) make  an  election,  on
behalf of each REMIC created  hereunder,  to be treated as a REMIC on the federal tax return of such REMIC
for its first taxable year, in accordance with the REMIC Provisions;  and  (iii) prepare  and forward,  or
cause to be prepared and forwarded,  to the  Certificateholders  and to any governmental  taxing authority
all  information  reports  as and when  required  to be  provided  to them in  accordance  with the  REMIC
Provisions.   The  expenses  of  preparing   and  filing  such  returns   shall  be  borne  by  the  Trust
Administrator.  The  Depositor,  the Master  Servicer and the related  Servicer  shall provide on a prompt
and timely basis to the Trust  Administrator  or its designee such  information with respect to each REMIC
created  hereunder  as  is in  their  possession  and  reasonably  required  or  requested  by  the  Trust
Administrator to enable it to perform its obligations under this subsection.

                  In its  capacity  as  attorney  in  fact  and as  the  tax  matters  person,  the  Trust
Administrator  shall  also:  (A) act on behalf of each REMIC  created  hereunder  in  relation  to any tax
matter or  controversy  involving the Trust Fund,  (B) represent the Trust Fund in any  administrative  or
judicial  proceeding  relating  to an  examination  or audit by any  governmental  taxing  authority  with
respect  thereto and (C) cause to be paid solely from the sources  provided herein the amount of any taxes
imposed  on each  REMIC  created  hereunder  when  and as the  same  shall be due and  payable  (but  such
obligation shall not prevent the Trust  Administrator or any other appropriate  Person from contesting any
such tax in  appropriate  proceedings  and shall not  prevent  the Trust  Administrator  from  withholding
payment of such tax, if permitted by law, pending the outcome of such proceedings).

(e)      The Trust  Administrator  shall  provide  (i) to any  transferor of a Residual  Certificate  such
information  as is  necessary  for the  application  of any tax  relating  to the  transfer  of a Residual
Certificate  to  any  Person  who is not a  permitted  transferee,  (ii) to  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 and  (iii) to  the  Internal  Revenue
Service  the  name,  title,   address  and  telephone  number  of  the  person  who  shall  serve  as  the
representative of each REMIC created hereunder.

(f)      The Trustee, to the extent directed by the Trust  Administrator,  the Depositor and the Holder of
the Residual  Certificates  shall take any action or cause the Trust Fund to take any action  necessary to
create or maintain the status of each REMIC created  hereunder as a REMIC under the REMIC  Provisions  and
shall  assist each other as  necessary to create or maintain  such  status.  Neither the  Trustee,  to the
extent  directed  or (in the case of a failure to act) not  directed by the Trust  Administrator,  nor the
Holder of the  Residual  Certificates  shall take any  action,  cause the Trust Fund to take any action or
fail to take (or fail to cause the Trust Fund to take) any action  that,  under the REMIC  Provisions,  if
taken or not taken, as the case may be, could  (i) endanger the status of each REMIC created  hereunder as
a REMIC or  (ii) result in the  imposition of a tax upon a REMIC  (including,  but not limited to, the tax
on prohibited transactions as defined in Code  Section 860F(a)(2) and the tax on prohibited  contributions
set forth in  Section 860G(d) of  the Code)  (either  such event,  an "Adverse  REMIC  Event")  unless the
Trustee  and the Trust  Administrator  have  received an Opinion of Counsel  (at the  expense of the party
seeking to take such action) to the effect that the  contemplated  action  shall not endanger  such status
or result in the imposition of such a tax.

                  The  Trustee  and the  Trust  Administrator  shall  not take or fail to take any  action
(whether or not  authorized  hereunder) as to which the Master  Servicer,  a Servicer or the Depositor has
advised it in writing  that it has  received  an  Opinion of Counsel to the effect  that an Adverse  REMIC
Event could occur with  respect to such action.  In  addition,  prior to taking any action with respect to
a REMIC or their  assets,  or  causing  any  REMIC  created  hereunder  to take any  action,  which is not
expressly  permitted  under the terms of this  Agreement,  the Trustee and the Trust  Administrator  shall
consult with the Master  Servicer,  the Servicers and the Depositor or their designees,  in writing,  with
respect to whether  such  action  could cause an Adverse  REMIC  Event to occur with  respect to any REMIC
created  hereunder  and the  Trustee and the Trust  Administrator  shall not take any such action or cause
that REMIC to take any such action as to which the Master  Servicer,  any  Servicer or the  Depositor  has
advised it in writing that an Adverse REMIC Event could occur.

                  In addition,  prior to taking any action with respect to any REMIC created  hereunder or
the assets  therein,  or causing any REMIC  created  hereunder to take any action,  which is not expressly
permitted under the terms of this Agreement,  the Holder of the Residual  Certificates  shall consult with
the Trust  Administrator or its designee,  in writing,  with respect to whether such action could cause an
Adverse  REMIC Event to occur with respect to any REMIC created  hereunder,  and no such Person shall take
any  action or cause  the Trust  Fund to take any such  action  as to which  the Trust  Administrator  has
advised it in writing  that an Adverse  REMIC Event could occur.  The Trustee and the Trust  Administrator
may consult  with counsel to make such  written  advice,  and the cost of same shall be borne by the party
seeking to take action not permitted by this Agreement.

                  At all times as may be  required  by the Code,  the Trust  Administrator  shall,  to the
extent  within its  control  and the scope of its duties  more  specifically  set forth  herein,  maintain
substantially  all of the assets of each REMIC created  hereunder as  "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.

(g)      In the  event  that  any  tax is  imposed  on  "prohibited  transactions"  of any  REMIC  created
hereunder,  as defined in  Section 860F(a)(2)  of the Code, on "net income from  foreclosure  property" of
such REMIC, as defined in  Section 860G(c) of  the Code, on any contributions to a REMIC after the Startup
Day  therefor  pursuant  to  Section 860G(d) of  the Code,  or any other tax is imposed by the Code or any
applicable  provisions of state or local tax laws, such tax shall be charged (i) to the related  Servicer,
if such  Servicer has in its sole  discretion  determined  to indemnify the Trust Fund against such tax or
if such tax arises out of or results from a breach of such  Servicer's  duties  under  (x) Section 2.07(j)
of this  Agreement  to not  enter  into any  arrangement  by which a REMIC  would  receive  a fee or other
compensation  for  services  or to permit  such  REMIC to  receive  any  income  from  assets  other  than
"qualified  mortgages"  or  "permitted  investments,"  (y) Section 3.01  of this  Agreement to not make or
permit any  modification,  waiver or amendment of any  Mortgage  Loan which would cause any REMIC  created
hereunder to fail to qualify as a REMIC or result in the  imposition  of any tax under  Section 860F(a) or
Section 860G(d) of  the Code or (z)  Section 3.11(c) of  this Agreement to not cause any  REO Property  to
fail to qualify as  "foreclosure  property"  within the  meaning of  Section 860G(a)(8)  of the Code or to
subject any REMIC created  hereunder to the imposition of any federal,  state or local income taxes on the
income earned from such Mortgaged  Property under  Section 860G(c) of  the Code of otherwise,  (ii) to the
Master  Servicer,  if such tax arises out of or results from a breach by the Master Servicer of any of its
obligations  under this  Agreement or if the Master  Servicer  has in its sole  discretion  determined  to
indemnify  the Trust Fund against such tax,  (iii) to the Trust  Administrator,  if such tax arises out of
or results  from a breach by the Trust  Administrator  of any of its  obligations  under this  Article II,
(iv) to  the  Trustee,  if such tax arises out of or  results  from a breach by the  Trustee of any of its
obligations  under this Article II or (v) otherwise  against amounts on deposit in the Collection  Account
as provided by Section 3.08 and on the Distribution  Date(s)  following such  reimbursement  the aggregate
of such taxes shall be allocated in reduction of the Interest  Distribution  Amount on each Class entitled
thereto in the same manner as if such taxes constituted a Prepayment Interest Shortfall.

                  In accordance with  Section 2.07(c),  the related  Servicer,  the Master  Servicer,  the
Trustee or the Trust  Administrator,  as applicable,  shall promptly deposit in the Certificate Account or
Collection Account, as applicable, any amount of such tax.

                  For  purposes  of  this  Section 2.07(g),  a tax is  imposed  following  the  final  and
unappealable  determination  under the Code of the amount of such tax and  written  notice  thereof by the
Tax Matters Person to the party to be charged.

                  The failure of the Master  Servicer or the related  Servicer to promptly  deposit in the
Certificate  Account or Collection  Account,  as  applicable,  any amount of such tax shall be an Event of
Default, as provided in Section 8.01(b).

(h)      The Trust Administrator  shall, for federal income tax purposes,  maintain books and records with
respect to each REMIC  created  hereunder on a calendar  year and on an accrual  basis or as otherwise may
be required by the REMIC Provisions.

(i)      Following  the  Startup  Day,  none of any  Servicer,  the Trustee  (which  shall act only at the
direction of the Trust  Administrator  or as otherwise  specifically  provided in this  Agreement)  or the
Trust  Administrator  shall  accept any  contributions  of assets to any REMIC  created  hereunder  unless
(subject to Section 2.05)  such Servicer,  the Trustee or the Trust  Administrator  shall have received an
Opinion of Counsel  (at the  expense of the party  seeking to make such  contribution)  to the effect that
the  inclusion  of such  assets in a REMIC  will not cause that REMIC to fail to qualify as a REMIC at any
time that any Certificates  are  outstanding,  or subject that REMIC to any tax under the REMIC Provisions
or other applicable provisions of federal, state and local law or ordinances.

(j)      None  of any  Servicer,  the  Trustee  (which  shall  act  only  at the  direction  of the  Trust
Administrator or as otherwise  specifically  provided in this Agreement) or the Trust  Administrator shall
(subject  to  Section 2.05)  enter  into any  arrangement  by which a REMIC  will  receive  a fee or other
compensation  for services  nor permit such REMIC 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.

(k)      Within 30 days after the  Closing  Date,  the Trust  Administrator  shall  apply to the  Internal
Revenue  Service for an employer  identification  number for each REMIC  created  hereunder  by means of a
Form SS-4 or other  acceptable  means and prepare and file with the  Internal  Revenue  Service Form 8811,
"Information  Return for Real Estate Mortgage  Investment  Conduits (REMIC) and Issuers of  Collateralized
Debt Obligations" for each REMIC created hereunder.

(l)      None of the Trustee  (which  shall act only at the  direction  of the Trust  Administrator  or as
otherwise  specifically provided in this Agreement),  the Trust Administrator,  the Master Servicer or any
Servicer shall sell,  dispose of or substitute  for any of the Mortgage  Loans (except in connection  with
(i) the  default,  imminent  default or foreclosure of a Mortgage Loan,  including but not limited to, the
acquisition or sale of a Mortgaged Property acquired by deed in lieu of foreclosure,  (ii) the  bankruptcy
of any REMIC created hereunder,  (iii) the  termination of any REMIC created hereunder pursuant to Article
X of  this  Agreement  or  (iv) a  purchase  of  Mortgage  Loans  pursuant  to  Article  II or III of this
Agreement)  nor acquire any assets for a REMIC,  nor sell or dispose of any  investments in the Collection
Account or the  Certificate  Account  for gain nor accept any  contributions  to a REMIC after the Closing
Date  (a) unless  it has  received  an Opinion of Counsel  that such sale,  disposition,  substitution  or
acquisition will not affect  adversely the status of any REMIC created  hereunder as a REMIC or (b) unless
the Master  Servicer or such Servicer has  determined  in its sole  discretion to indemnify the Trust Fund
against such tax.

(m)      In order to enable  the Trust  Administrator  to  perform  its  duties as set forth  herein,  the
Depositor  shall provide,  or cause to be provided to the Trust  Administrator,  within ten days after the
Closing Date, all information or data the Trust  Administrator  determines to be relevant for tax purposes
to the valuations and offering  prices of the  Certificates,  including,  without  limitation,  the price,
yield,  prepayment  assumption and projected cash flows of the Certificates and the Mortgage Loans and the
Trust  Administrator  shall  be  entitled  to rely  upon  any and all  such  information  and  data in the
performance  of its duties set forth herein.  Thereafter,  the Master  Servicer  shall  provide,  promptly
upon  request  therefor,  any  such  additional  information  or  data  that  the  Trustee  or  the  Trust
Administrator  may from time to time  reasonably  request  in order to enable  the  Trustee  and the Trust
Administrator  to perform  their  duties as set forth  herein and the Trustee and the Trust  Administrator
shall be  entitled to rely upon any and all such  information  and data in the  performance  of its duties
set forth  herein.  DLJMC shall  indemnify  the Trust  Administrator  and hold it  harmless  for any loss,
liability,  damage, claim or expense of the Trust Administrator  arising from any failure of the Depositor
to provide,  or to cause to be provided,  accurate  information  or data to the Trust  Administrator  on a
timely basis.  The Master  Servicer shall  indemnify the Trustee and the Trust  Administrator  and hold it
harmless  for any loss,  liability,  damage,  claim or expense of the Trustee and the Trust  Administrator
arising  from any  failure  of the  Master  Servicer  to  provide,  or to cause to be  provided,  accurate
information  or data  required  to be  provided  by the  Master  Servicer  to the  Trustee  and the  Trust
Administrator  on a timely  basis;  provided,  however,  that if any  Servicer  shall fail to provide such
information to the Master Servicer upon timely request for such information by the Master  Servicer,  that
Servicer  shall  indemnify  the Master  Servicer,  the  Trustee  and the Trust  Administrator  and hold it
harmless for any loss,  liability,  damage,  claim or expense of the Master Servicer,  the Trustee and the
Trust  Administrator  arising  from any failure of that  Servicer to provide,  or to cause to be provided,
the  information  referred to above on a timely basis.  The  indemnification  provisions  hereunder  shall
survive the  termination of this  Agreement and shall extend to any co-trustee and co-Trust  Administrator
appointed pursuant to this Agreement.

(n)      The Trust  Administrator  shall  account for the rights of the Holders of the LIBOR  Certificates
to receive  payments in respect of Basis Risk  Shortfalls and the rights of the Holders of the Class 4-A-2
Certificates  to receive  payments from the  Supplemental  Interest  Account as rights in an interest rate
cap  contract  written  by the  Class 4-X  Certificateholders  in  favor  of  the  Holders  of  the  LIBOR
Certificates  and not as an  obligation of  REMIC III,  whose  obligation to pay interest on the REMIC III
Regular  Interests  evidenced  by such  Certificates  will be subject to a cap equal to the Net Funds Cap.
The Trust  Administrator  shall  account  for such rights as property  held  separate  and apart from such
REMIC III Regular  Interests  as required by Treasury  regulation  section  1.860G-2(i).  Any amounts paid
from  the  Interest  Remittance  Amount  or  Principal  Remittance  Amount  to the  holders  of the  LIBOR
Certificates  in respect of Basis Risk  Shortfalls or to the  Supplemental  Interest  Trust for payment to
the Swap  Counterparty  shall be deemed to have first been  distributed  from REMIC III to the  holders of
the Class 4-X  Certificates in respect of REMIC III Regular  Interest 4-X-IO and then paid by such holders
to the holders of the LIBOR  Certificates or the Supplemental  Interest Trust, as applicable.  Any amounts
distributed to the holders of the  Class 4-A-2  Certificates  by the Trust  Administrator  from amounts it
receives  from the  Supplemental  Interest  Account shall be deemed to have first been paid outside of any
REMIC to the  holders  of the  Class 4-X  Certificates  in  respect of their  rights  with  respect to the
Supplemental  Interest  Trust and then  paid  outside  of any  REMIC by such  holders  to  holders  of the
Class 4-A-2  Certificates.  In addition, the Class 4-X  Certificateholders shall be deemed to have entered
into a contractual  arrangement with the Class AR and Class AR-L  Certificateholders  whereby the Class AR
and Class AR-L  Certificateholders  agree to pay to the Class 4-X  Certificateholders on each Distribution
Date amounts that would, in the absence of such contractual  agreement,  be distributable  with respect to
the residual interest in REMIC III pursuant to  Section 4.01(II)(d)(xv)  (which amounts are expected to be
zero).  Thus each Group 4 Senior  Certificate and Class 4-M  Certificate  shall be treated as representing
ownership  of not only a REMIC III  Regular  Interest,  but also  ownership  of an interest in an interest
rate cap contract.  Each  Class 4-X  Certificate  shall be treated as  representing  ownership of not only
two  REMIC III  Regular  Interests,  but  also  ownership  of an  obligation  under an  interest  rate cap
contract.  For purposes of  determining  the issue price of the  REMIC III  Regular  Interests,  the Trust
Administrator shall assume that the interest rate cap contract has a value of $5,000.

                  For any  Distribution  Date on which there is a payment  under a Group 4  Interest  Rate
Cap  Agreement  based on a  notional  balance  in excess of the Class  Principal  Balance  of the  related
Group 4 Certificates,  the amount representing such excess payment shall not be an asset of the Trust and,
instead,  shall be paid into and  distributed  out of a separate  trust created by this  Agreement for the
benefit of the related Group 4  Certificates and shall be distributed to the related Group 4  Certificates
pursuant to  Section 4.01(II).  The Trust  Administrator  shall not be  responsible  for any tax reporting
with respect to such separate trust.

SECTION 2.08.     Covenants of the Master Servicer and each Servicer.

                  The Master Servicer and each Servicer,  severally and not jointly,  hereby  covenants to
the Depositor, the Trustee and the Trust Administrator as follows:

(a)      Such Servicer or the Master  Servicer shall comply in the  performance of its  obligations  under
this Agreement  with all reasonable  rules and  requirements  of the insurer under each Mortgage  Guaranty
Insurance Policy; and

(b)      No written  information,  certificate  of an officer,  statement  furnished in writing or written
report  delivered  to  the  Depositor,   any  affiliate  of  the  Depositor,  the  Trustee  or  the  Trust
Administrator  and  prepared by the Master  Servicer or such  Servicer  pursuant to this  Agreement  shall
contain any untrue statement of a material fact.

                                                ARTICLE III

                                       ADMINISTRATION AND SERVICING
                                            OF MORTGAGE LOANS

SECTION 3.01.     Servicers to Service Mortgage Loans.

                  For and on behalf of the  Certificateholders,  as independent  contractors of the Trust,
(i) each  Servicer,  severally and not jointly,  shall service and administer  the related  Non-Designated
Mortgage Loans in accordance  with the terms of this Agreement and with Accepted  Servicing  Practices and
with  all  applicable  requirements  of  the  Servicing  Criteria,  (ii) the  Master  Servicer  shall,  in
accordance  with  Section 3.03  of this  Agreement,  master  service  and  administer  the  Non-Designated
Mortgage  Loans by overseeing  and enforcing the  servicing of the  Non-Designated  Mortgage  Loans by the
related  Servicer  according to the terms of this  Agreement  and  (iii) the  Master  Servicer  shall,  in
accordance  with the  Section 3.20  of this  Agreement,  master  service  and  administer  the  Designated
Mortgage Loans by overseeing  and enforcing the servicing of the Designated  Mortgage Loans by the related
Designated  Servicer  according  to  the  terms  of  the  related  Designated  Servicing  Agreement.   The
obligations of each of SPS,  GreenPoint  and Wells Fargo  hereunder to service and administer the Mortgage
Loans shall be limited to the SPS Serviced  Mortgage  Loans,  GreenPoint  Serviced  Mortgage Loans and the
Wells Fargo  Serviced  Mortgage  Loans,  respectively;  and with respect to the duties and  obligations of
each  Servicer,  references  herein to related  "Mortgage  Loans"  shall be  limited  to the SPS  Serviced
Mortgage  Loans (and the related  proceeds  thereof and related REO  Properties)  in the case of SPS,  the
GreenPoint  Serviced  Mortgage Loans (and the related  proceeds thereof and related REO Properties) in the
case of GreenPoint  and the Wells Fargo  Serviced  Mortgage  Loans (and the related  proceeds  thereof and
related  REO  Properties)  in the case of  Wells  Fargo;  and in no  event  shall  any  Servicer  have any
responsibility  or liability  with respect to any of the other  Mortgage  Loans.  The  obligations  of the
Master  Servicer to master service and administer  the  Non-Designated  Mortgage Loans shall be limited to
the Wells Fargo  Serviced  Mortgage  Loans,  the SPS Serviced  Mortgage  Loans,  the  GreenPoint  Serviced
Mortgage  Loans  and  the  Special  Serviced  Mortgage  Loans.  In  connection  with  such  servicing  and
administration  of the  Non-Designated  Mortgage  Loans,  the Master Servicer and each Servicer shall have
full power and authority,  acting alone and/or through  Sub-Servicers as provided in Section 3.02  hereof,
to do or cause to be done any and all things that it may deem  necessary or desirable in  connection  with
such servicing and administration,  including but not limited to, the power and authority,  subject to the
terms hereof (i) to  execute and deliver,  on behalf of the  Certificateholders  and the Trust,  customary
consents or waivers and other  instruments  and documents,  (ii) to  consent to transfers of any Mortgaged
Property and  assumptions of the Mortgage Notes and related  Mortgages (but only in the manner provided in
this  Agreement),  (iii) to collect any Insurance  Proceeds and other  Liquidation  Proceeds,  and (iv) to
effectuate  foreclosure  or other  conversion  of the  ownership of the  Mortgaged  Property  securing any
Mortgage  Loan;  provided,  that neither the Master  Servicer nor a Servicer shall take any action that is
inconsistent  with  or  prejudices  the  interests  of the  Trust  Fund or the  Certificateholders  in any
Mortgage Loan or the rights and interests of the Depositor,  the Trustee,  the Trust  Administrator or the
Certificateholders  under this  Agreement.  The Master  Servicer and each  Servicer  shall  represent  and
protect the  interests of the Trust Fund in the same manner as it protects  its own  interests in mortgage
loans in its own portfolio in any claim,  proceeding or litigation  regarding a Mortgage  Loan,  and shall
not make or permit any  modification,  waiver or amendment of any Mortgage Loan that would cause any REMIC
created  hereunder  to  fail  to  qualify  as a  REMIC  or  result  in the  imposition  of any  tax  under
Section 860F(a) or  Section 860G(d) of  the Code.  Without  limiting the generality of the foregoing,  the
Master  Servicer and each  Servicer,  in its own name or in the name of the  Depositor  and the Trust,  is
hereby authorized and empowered by the Depositor,  the Trust and the Trust Administrator,  when the Master
Servicer or such Servicer believes it appropriate in its reasonable  judgment,  to execute and deliver, on
behalf of the Trust, the Trustee, the Trust Administrator,  the Depositor,  the  Certificateholders or any
of them,  any and all  instruments  of  satisfaction  or  cancellation,  or of partial or full  release or
discharge and all other  comparable  instruments,  with respect to the Mortgage Loans, and with respect to
the Mortgaged  Properties  held for the benefit of the  Certificateholders.  The Master  Servicer and each
Servicer  shall prepare and deliver to the  Depositor  and/or the Trustee  and/or the Trust  Administrator
such  documents  requiring  execution  and  delivery  by  either  or  both of  them  as are  necessary  or
appropriate  to enable the Master  Servicer or such Servicer to master  service and  administer or service
and  administer  the  Mortgage  Loans,  as  applicable,  to the extent  that the Master  Servicer  or such
Servicer is not  permitted  to execute and deliver  such  documents  pursuant to the  preceding  sentence.
Upon  receipt of such  documents,  the  Depositor  and/or the  Trustee  or the Trust  Administrator  shall
execute such documents and deliver them to the Master Servicer or such Servicer.

                  In  accordance  with the  standards  of the first  paragraph  of this  Section 3.01  and
unless  determined in good faith to be a Nonrecoverable  Advance,  each Servicer shall advance or cause to
be advanced  funds as necessary for the purpose of effecting the payment of taxes and  assessments  on the
Mortgaged  Properties related to the Non-Designated  Mortgage Loans, which advances  constitute  Servicing
Advances and shall be  reimbursable  in the first  instance from related  collections  from the Mortgagors
pursuant to  Section 3.06,  and further as provided  in  Section 3.08.  In no event shall any  Servicer be
required to make any  Servicing  Advance  which  would  constitute  a  Nonrecoverable  Advance.  The costs
incurred  by a  Servicer,  if any,  in  effecting  the timely  payments  of taxes and  assessments  on the
Mortgaged  Properties  related to the  Non-Designated  Mortgage Loans and related insurance premiums shall
not, for the purpose of  calculating  monthly  distributions  to the  Certificateholders,  be added to the
Stated Principal Balances of the related  Non-Designated  Mortgage Loans,  notwithstanding  that the terms
of such Non-Designated  Mortgage Loans so permit;  provided,  however,  that the limitations  contained in
this  sentence  shall not apply to  modifications  made pursuant to  Section 3.05(a).  The parties to this
Agreement  acknowledge  that  Servicing  Advances  shall be  reimbursable  pursuant  to the  terms of this
Agreement  and agree that no Servicing  Advance shall be rejected or disallowed by any party unless it has
been shown that such Servicing Advance was not made in accordance with this Agreement.

                  Each Servicer  hereby  acknowledges  that,  to the extent such  Servicer has  previously
serviced some or all of the  Non-Designated  Mortgage Loans pursuant to another servicing  agreement,  the
servicing  provisions  contained in this Agreement shall supersede the servicing  provisions  contained in
such  other  servicing  agreement  from and after the  Closing  Date,  except  that such  other  servicing
agreement shall survive and govern with respect to excess  servicing fees and  termination  without cause.
In addition,  the Master  Servicer  hereby  acknowledges  that,  to the extent the Master  Servicer or any
Designated  Servicer has  previously  serviced some or all of the  Designated  Mortgage  Loans pursuant to
another  servicing  agreement,  the provisions  contained in the related  Designated  Servicing  Agreement
shall  supersede the  provisions  contained in such other  servicing  agreement from and after the Closing
Date.

                  Notwithstanding  anything  in  this  Agreement  to the  contrary,  the  purchase  of any
GreenPoint  Serviced  Mortgage Loan by any Person shall be subject to the rights of GreenPoint to continue
servicing such GreenPoint  Serviced  Mortgage Loan for the same Servicing Fee  substantially in accordance
with the terms of this  Agreement  and the  purchase  of any Wells  Fargo  Serviced  Mortgage  Loan by any
Person  shall be subject to the rights of Wells Fargo to  continue  servicing  such Wells  Fargo  Serviced
Mortgage Loan for the same Servicing Fee substantially in accordance with the terms of this Agreement.

                  With  respect to each  Mortgage  Loan,  the related  Servicer  shall fully  furnish,  in
accordance  with the Fair Credit  Reporting Act and its  implementing  regulations,  accurate and complete
information  (e.g., favorable  and  unfavorable)  on its borrower  credit  files to Equifax,  Experian and
Trans Union Credit Information Company, on a monthly basis.

                  Each  Servicer  is  authorized   and  empowered  by  the  Trustee,   on  behalf  of  the
Certificateholders  and the Trustee,  in its own name or in the name of any Sub-Servicer,  when a Servicer
or any  Sub-Servicer,  as the case may be,  believes it  appropriate  in its best judgment to register any
related  Mortgage Loan on the MERS® System,  or cause the removal from the  registration  of such Mortgage
Loan on the MERS® System, to execute and deliver, on behalf of the Trustee and the  Certificateholders  or
any of them, any and all instruments of assignment and other  comparable  instruments with respect to such
assignment or  re-recording  of a Mortgage in the name of MERS,  solely as nominee for the Trustee and its
successors and assigns.

SECTION 3.02.     Subservicing; Enforcement of the Obligations of Sub-Servicers.

(a)      The  Non-Designated  Mortgage Loans may be subserviced by a Sub-Servicer on behalf of the related
Servicer in accordance with the servicing  provisions of this Agreement;  provided,  that the Sub-Servicer
must be a  FNMA-approved  lender  or a  FHLMC  seller/servicer  in  good  standing.  With  respect  to the
Non-Designated Mortgage Loans, each Servicer may perform any of its servicing  responsibilities  hereunder
or may cause the Sub-Servicer to perform any such servicing  responsibilities  on its behalf,  but the use
by such  Servicer  of the  Sub-Servicer  shall  not  release  such  Servicer  from any of its  obligations
hereunder  and such  Servicer  shall  remain  responsible  hereunder  for all acts  and  omissions  of the
Sub-Servicer  as fully as if such acts and  omissions  were those of such  Servicer.  With  respect to the
Non-Designated  Mortgage Loans, each Servicer shall pay all fees and expenses of any Sub-Servicer  engaged
by such Servicer from its own funds.

                  A Servicer  shall not permit a  Sub-Servicer  to perform any servicing  responsibilities
hereunder  with respect to the  Non-Designated  Mortgage  Loans unless that  Sub-Servicer  first agrees in
writing  with  such  Servicer  to  deliver  an  1123  Certificate,  an  Assessment  of  Compliance  and an
Accountant's  Attestation  in such  manner and at such times that  permits  that  Servicer  to comply with
Sections 13.06, 13.07 and 13.08 of this Agreement.

                  Notwithstanding the foregoing,  with respect to the Non-Designated  Mortgage Loans, each
Servicer  shall be entitled to outsource one or more separate  servicing  functions to a Person (each,  an
"Outsourcer")  that  does  not meet  the  eligibility  requirements  for a  Sub-Servicer,  so long as such
outsourcing  does  not  constitute  the  delegation  of  such  Servicer's  obligation  to  perform  all or
substantially  all of the servicing of the related  Non-Designated  Mortgage Loans to such Outsourcer.  In
such event,  the use by a Servicer of any such Outsourcer  shall not release the related Servicer from any
of its  obligations  hereunder  and such  Servicer  shall remain  responsible  hereunder  for all acts and
omissions of such  Outsourcer  as fully as if such acts and  omissions  were those of such  Servicer,  and
such Servicer shall pay all fees and expenses of the Outsourcer from such Servicer's own funds.

                  A Servicer shall not outsource one or more separate servicing  functions  hereunder with
respect to the Non-Designated  Mortgage Loans to any Subcontractor  unless that Subcontractor first agrees
in writing with such Servicer to deliver an Assessment of Compliance  and an  Accountant's  Attestation in
such manner and at such times that permits that Servicer to comply with  Sections  13.07 and 13.08 of this
Agreement.

                  Each  Servicer  may in  connection  with its  duties as  Servicer  hereunder  enter into
transactions  with any of its Affiliates  relating to the  Non-Designated  Mortgage  Loans;  provided that
(a) such  Servicer  acts  (i) in  accordance  with  Accepted  Servicing  Practices  and the  terms of this
Agreement,  and  (ii) in the  ordinary  course of business  of such  Servicer;  and (b) the  terms of such
transaction  are no less  favorable to such  Servicer  than it would  obtain in a comparable  arm's-length
transaction  with a Person  that is not an  Affiliate  of such  Servicer.  Notwithstanding  the  preceding
sentence,  any such  transaction  between a Servicer  and any of its  Affiliates  shall not  release  such
Servicer from any of its obligations  hereunder and such Servicer shall remain  responsible  hereunder for
all acts and omissions of such  Affiliate  with respect to such Mortgage  Loans serviced by it as fully as
if such  acts  and  omissions  were  those  of such  Servicer.  Any fees  and  expenses  relating  to such
transaction  between such Servicer and its Affiliate that are not otherwise  reimbursable to such Servicer
pursuant to this  Agreement  shall be borne by the  parties  thereto and shall not be an expense or fee of
the Trust, the Depositor, the Trustee, the Trust Administrator, the Seller or the Master Servicer.

(b)      With  respect to any  Non-Designated  Mortgage  Loans,  at the cost and  expense  of a  Servicer,
without any right of  reimbursement  from the  Depositor,  the  Trustee,  the Trust  Administrator  or the
applicable   Collection   Account,   such  Servicer   shall  be  entitled  to  terminate  the  rights  and
responsibilities  of its Sub-Servicer and arrange for any servicing  responsibilities to be performed by a
successor  Sub-Servicer  meeting the requirements set forth in Section 3.02(a),  provided,  however,  that
nothing  contained  herein  shall be deemed to prevent  or  prohibit  such  Servicer,  at such  Servicer's
option,  from electing to service the related  Non-Designated  Mortgage Loans itself.  In the event that a
Servicer's  responsibilities and duties under this Agreement are terminated pursuant to Section 8.01,  and
if requested to do so by the Trustee or Trust  Administrator  or such Servicer  shall, at its own cost and
expense  terminate  the  rights  and  responsibilities  of  its  Sub-Servicer  as  soon  as is  reasonably
possible.  Each  Servicer  shall pay all fees,  expenses or penalties  necessary in order to terminate the
rights and  responsibilities  of its  Sub-Servicer  from such  Servicer's  own funds  without any right of
reimbursement from the Depositor, Trustee, Trust Administrator, or the applicable Collection Account.

(c)      Notwithstanding  any of the provisions of this Agreement  relating to agreements or  arrangements
between a Servicer and its  Sub-Servicer  or a Servicer and its  Outsourcer,  or any  reference  herein to
actions taken through the Sub-Servicer,  the Outsourcer,  or otherwise,  the related Servicer shall not be
relieved  of  its  obligations  to  the  Depositor,   the  Trust,  Trustee,  the  Trust  Administrator  or
Certificateholders  and shall be obligated to the same extent and under the same terms and  conditions  as
if it alone were servicing and  administering  the related  Non-Designated  Mortgage Loans.  Each Servicer
shall be entitled to enter into an agreement with its Sub-Servicer and Outsourcer for  indemnification  of
such Servicer by such Sub-Servicer or Outsourcer,  as applicable,  and nothing contained in this Agreement
shall be deemed to limit or modify such indemnification.

                  For  purposes  of this  Agreement,  a  Servicer  shall be  deemed to have  received  any
collections,  recoveries or payments with respect to the related  Non-Designated  Mortgage  Loans that are
received by a related  Sub-Servicer  regardless of whether such payments are remitted by the  Sub-Servicer
to such Servicer.

                  Any  Subservicing  Agreement  and any other  transactions  or  services  relating to the
Non-Designated  Mortgage Loans  involving a Sub-Servicer  shall be deemed to be between the  Sub-Servicer,
and the related  Servicer  alone,  and the Depositor,  the Trustee,  the Trust  Administrator,  the Master
Servicer,  the other Servicers and the Special  Servicer shall have no obligations,  duties or liabilities
with respect to a Sub-Servicer including no obligation,  duty or liability of the Depositor,  Trustee, the
Trust   Administrator,   the  Master  Servicer,   the  Special  Servicer  or  other  Servicers  to  pay  a
Sub-Servicer's fees and expenses.

(d)      Each  Servicer  is hereby  authorized  to enter  into a  financing  or other  facility  (any such
arrangement,  a  "Facility")  under  which  (i) such  Servicer  assigns or  pledges  to another  person (a
"Lender")  (A) such  Servicer's rights under this Agreement to be reimbursed for any Advances or Servicing
Advances,  and  (B) any  and all  rights  of such  Servicer  under  this  Agreement  resulting  from  such
Servicer's  performance of its  obligations  under this  Agreement,  including,  without  limitation,  any
Servicing  Fees,  interest  income,  Ancillary  Income,  and other payments  received by such Servicer for
servicing  the Mortgage  Loans  related  thereto and (ii) the  Lender  agrees to fund some or all Advances
and/or  Servicing  Advances  required to be made by such Servicer  pursuant to this Agreement.  No consent
of the Trustee,  Trust  Administrator,  Master  Servicer,  Certificateholders,  Rating Agency or any other
party is required before such Servicer may enter into a Facility;  provided,  however, that the consent of
the Trust  Administrator  shall be required  before such Servicer may cause to be  outstanding at one time
more than one  Facility.  Notwithstanding  the  existence  of any  Facility,  such  Servicer  shall remain
obligated  pursuant to this Agreement to make Advances and Servicing  Advances pursuant to and as required
by this  Agreement,  and to perform all duties and  obligations  of such Servicer under this Agreement and
shall not be relieved of such obligations by virtue of such Facility.

SECTION 3.03.     Master Servicing by Master Servicer.

                  For and on behalf of the  Certificateholders,  the Master  Servicer  shall  oversee  and
enforce the  obligation  of Wells  Fargo,  GreenPoint  and SPS to service and  administer  the Wells Fargo
Serviced   Mortgage  Loans,   GreenPoint   Serviced  Mortgage  Loans  and  SPS  Serviced  Mortgage  Loans,
respectively,  in accordance  with the terms of this  Agreement and shall have full power and authority to
do any and all things which it may deem  necessary or desirable in connection  with such master  servicing
and  administration.  In performing its obligations  hereunder,  the Master Servicer shall act in a manner
consistent  with this  Agreement and with  customary and usual  standards of practice of prudent  mortgage
loan master  servicers.  Furthermore,  the Master Servicer shall oversee and consult with the Servicers as
necessary from  time-to-time  to carry out the Master  Servicer's  obligations  hereunder,  shall receive,
review and  evaluate  all  reports,  information  and other data  provided  to the Master  Servicer by the
Servicers and shall cause each Servicer to perform and observe the covenants,  obligations  and conditions
to be performed or observed by such Servicer under this Agreement.

                  With respect to any  Distribution  Date, no later than the related Cash Remittance Date,
the Master  Servicer shall remit to the Trust  Administrator  for deposit in the  Certificate  Account the
amount of the Compensating  Interest Payment for the Master Servicer,  with respect to each Mortgage Loan,
for the  related  Prepayment  Period,  to the extent any of Wells  Fargo,  GreenPoint,  SPS or the related
Designated  Servicer,  as  applicable,  defaults  in its  obligation  to make such  Compensating  Interest
Payment  pursuant  to  Section 3.05.  The  aggregate  of such  deposits  shall  be made  from  the  Master
Servicer's own funds, without reimbursement therefor.

SECTION 3.04.     Trustee to Act as Master Servicer or Servicer.

                  In the event  that (A) the  Master  Servicer  shall  for any  reason no longer be Master
Servicer  hereunder or (B) any Servicer  shall for any reason no longer be a Servicer  hereunder and, with
respect to any Servicer,  the Master Servicer shall for any reason no longer be Master Servicer  hereunder
(including,  in each  case,  by  reason  of an Event of  Default),  the  Trustee  or its  successor  shall
thereupon  assume all of the rights and  obligations  of the Master  Servicer or such  Servicer  hereunder
arising  thereafter  (except that the Trustee shall not be (i) liable for losses of the Master Servicer or
such Servicer pursuant to Section 3.09  hereof or any acts or omissions of the related  predecessor of the
Master  Servicer or such Servicer  hereunder,  (ii) obligated  to make  Advances if it is prohibited  from
doing so by applicable law,  (iii) obligated to effectuate  repurchases or substitutions of Mortgage Loans
hereunder  including,  but not limited to,  repurchases  or  substitutions  of Mortgage  Loans pursuant to
Section 2.02 or 2.03 hereof or (iv) deemed to have made any  representations  and warranties of the Master
Servicer or such Servicer  hereunder);  (v) be obligated to perform any obligation of the Master  Servicer
or such Servicer  under  Section 13.06  or  Section 13.08  with respect to any period of time during which
the Trustee was not acting as the Master Servicer or Servicer).  Any such  assumption  shall be subject to
Section 8.02  hereof.  Notwithstanding  the  foregoing,  if the  Trustee has become the  successor  to the
Master  Servicer or a Servicer  hereunder,  the Trustee may, if it shall be unwilling to so act, or shall,
if it is unable to so act,  appoint,  or  petition  a court of  competent  jurisdiction  to  appoint,  any
established  mortgage loan servicing  institution,  the appointment of which does not adversely affect the
then-current  rating of the Certificates,  as the successor to the Master Servicer or a Servicer hereunder
in the  assumption  of all or any  part of the  responsibilities,  duties  or  liabilities  of the  Master
Servicer or such  Servicer,  as applicable,  provided that such  successor to the Master  Servicer or such
Servicer,  as  applicable,  shall  not be deemed to have made any  representation  or  warranty  as to any
Mortgage Loan made by the Master Servicer or such Servicer, as applicable.

                  Each  Servicer  shall,  upon request of the Trust  Administrator,  but at the expense of
such  Servicer,  deliver to the assuming  party all  documents and records  relating to each  Subservicing
Agreement or substitute  Subservicing  Agreement and the Mortgage Loans then being serviced thereunder and
hereunder by such  Servicer and an  accounting  of amounts  collected or held by it and  otherwise use its
best efforts to effect the orderly and  efficient  transfer of the  Subservicing  Agreement or  substitute
Subservicing Agreement to the assuming party.

SECTION 3.05.     Collection of Mortgage Loans; Collection Accounts; Certificate Account.

(a)      Continuously  from the date  hereof  until  the  principal  and  interest  on all  Non-Designated
Mortgage  Loans  have been paid in full or such  Non-Designated  Mortgage  Loans  have  become  Liquidated
Mortgage  Loans,  each Servicer shall proceed in accordance with Accepted  Servicing  Practices to collect
all payments due under each of the related  Non-Designated  Mortgage  Loans when the same shall become due
and payable to the extent  consistent  with this  Agreement  and the terms and  provisions  of any related
Mortgage  Guaranty  Insurance  Policy  and shall take  special  care with  respect  to the  Non-Designated
Mortgage  Loans for which a Servicer  collects  escrow  payments in  ascertaining  and  estimating  Escrow
Payments  and all other  charges  that will  become due and  payable  with  respect to the  Non-Designated
Mortgage  Loans and the related  Mortgaged  Properties,  to the end that the  installments  payable by the
related  Mortgagors  will be  sufficient  to pay such  charges as and when they  become  due and  payable.
Consistent  with the  foregoing,  in connection  with  Non-Designated  Mortgage Loans which it is directly
servicing,  each  Servicer  may in its  discretion  (i) waive  any late payment  charge or any  prepayment
charge or penalty  interest in  connection  with the  prepayment  of a  Non-Designated  Mortgage  Loan and
(ii) extend  the Due Dates for  payments  due on a Mortgage  Note for a period not greater  than 180 days;
provided,  however,  that no such  Servicer  can extend the maturity of any such  Non-Designated  Mortgage
Loan  past the date on which the final  payment  is due on the  latest  maturing  Mortgage  Loan as of the
Cut-off  Date.  In the event of any such  arrangement,  the related  Servicer  shall make  Advances on the
related  Non-Designated  Mortgage  Loans in  accordance  with the  provisions of  Section 5.01  during the
scheduled period in accordance with the amortization  schedule of such Mortgage Loan without  modification
thereof by reason of such  arrangements.  No Servicer shall be required to institute or join in litigation
with  respect to  collection  of any payment  (whether  under a Mortgage,  Mortgage  Note or  otherwise or
against any public or governmental  authority with respect to a taking or  condemnation)  if it reasonably
believes that enforcing the provision of the Mortgage or other  instrument  pursuant to which such payment
is required is prohibited by applicable  law.  Consistent  with the  foregoing,  instances when a Mortgage
Loan is in default or default is  reasonably  foreseeable  (within the  meaning of the REMIC  Provisions),
the  related  Servicer  may modify the terms of such  Mortgage  Loan to (1)  capitalize  to the  principal
balance thereof,  any unreimbursed  Monthly Advances,  unreimbursed  Servicing Advances,  unpaid Servicing
Fees, and related  amounts due to the related  Servicer with respect to such Mortgage Loan; (2) defer such
amounts  to a balloon  payment  due on the final  payment  date of such  Mortgage  Loan;  (3)  extend  the
maturity of any such  Mortgage  Loan,  but in no instance  past the date on which the final payment is due
on the latest  maturing  Mortgage  Loan as of the Cut-off Date;  and (4) reduce the related  Mortgage Rate
(provided  that the  Mortgage  Rate may not be  reduced  below the  Mortgage  Rate of such  Mortgage  Loan
immediately  prior to the related first adjustable  date),  provided,  however,  that the related Servicer
shall effect such  modification  only after the related  borrower has made no less than three  consecutive
monthly payments pursuant the terms of the proposed modification.

(b)      Each  Servicer  shall  segregate  and  hold  all  funds  collected  and  received  pursuant  to a
Non-Designated  Mortgage  Loan  separate and apart from any of its own funds and general  assets and shall
establish and maintain one or more Collection  Accounts,  in the form of time deposit or demand  accounts,
titled "[Servicer's  name], in trust for the Holders of Adjustable Rate Mortgage Trust 2006-3,  Adjustable
Rate  Mortgage-Backed  Pass-Through  Certificates,  Series 2006-3" or, if established  and maintained by a
Sub-Servicer  on  behalf  of a  Servicer,  "[Sub-Servicer's  name],  in trust  for  [Servicer's  name]" or
"[Sub-Servicer's  name], as agent,  trustee and/or bailee of principal and interest  custodial account for
[Servicer's  name],  its  successors  and assigns,  for various  owners of interest in  [Servicer's  name]
mortgage-backed  pools. In the event that a Sub-Servicer  employs a Sub-Servicer,  the Collection  Account
shall be  titled  "[name  of  Sub-Servicer's  sub-servicer],  in trust for  [Sub-Servicer's  name]."  Each
Collection  Account  maintained by each Servicer  (other than Wells Fargo),  shall be an Eligible  Account
acceptable to the Depositor  and the Trust  Administrator.  Each  Collection  Account  maintained by Wells
Fargo  shall be an  Eligible  Account.  Funds  deposited  in a  Collection  Account may be drawn on by the
related  Servicer in  accordance  with  Section 3.08.  Any funds  deposited in a Collection  Account shall
either be invested in Eligible  Investments or at all times be fully insured to the full extent  permitted
under applicable law.

(c)      Each Servicer shall deposit in the  applicable  Collection  Account on a daily basis,  within two
Business Days of receipt,  unless  otherwise  indicated,  and retain  therein,  the following  collections
remitted by  Sub-Servicers  or payments  received by such  Servicer  and  payments  made by such  Servicer
subsequent  to the Cut-off  Date,  other than  payments of  principal  and  interest  due on or before the
Cut-off Date:

(i)      all payments on account of  principal on the related  Non-Designated  Mortgage  Loans,  including
         all Principal Prepayments;

(ii)     all  payments on account of interest on the related  Non-Designated  Mortgage  Loans  adjusted to
         the per annum rate equal to the  Mortgage  Rate  reduced by the sum of the  related  Expense  Fee
         Rate, as applicable;

(iii)    all Liquidation Proceeds on the related Non-Designated Mortgage Loans;

(iv)     all Insurance  Proceeds on the related  Non-Designated  Mortgage Loans including amounts required
         to be deposited  pursuant to  Section 3.09  (other than proceeds to be held in the Escrow Account
         and applied to the  restoration or repair of the Mortgaged  Property or released to the Mortgagor
         in accordance with Section 3.09);

(v)      all Advances made by such Servicer pursuant to Section 5.01;

(vi)     no later than the withdrawal  from the Collection  Account  pursuant to  Section 3.08(a)(ix) each
         month,  the  applicable  amount of the  Compensating  Interest  Payment for such Servicer for the
         related  Prepayment  Period.  The aggregate of such deposits  shall be made from such  Servicer's
         own funds, without reimbursement therefor;

(vii)    any  amounts  required to be  deposited  by such  Servicer in respect of net monthly  income from
         REO Property related to any Non-Designated Mortgage Loan pursuant to Section 3.11;

(viii)   all Assigned Prepayment Premiums, if applicable; and

(ix)     any other amounts required to be deposited hereunder.

                  The  foregoing   requirements  for  deposit  into  each  Collection   Account  shall  be
exclusive,  it being understood and agreed that,  without  limiting the generality of the foregoing,  with
respect to the  Non-Designated  Mortgage  Loans,  Ancillary  Income need not be deposited by such Servicer
into such Collection  Account.  In addition,  notwithstanding  the provisions of this  Section 3.05,  each
Servicer  may deduct  from  amounts  received  by it,  prior to  deposit  into the  applicable  Collection
Account,  any portion of any  Scheduled  Payment  representing  (i) the  applicable  Servicing Fee and any
other  amounts  owed  to  such  Servicer   pursuant  to  Section 3.14   and  (ii) with   respect  to  each
Non-Designated  Mortgage Loan covered by a Lender Paid Mortgage  Guaranty  Insurance  Policy,  any amounts
required to effect timely payment of the premiums on such Mortgage  Guaranty  Insurance Policy pursuant to
Section 3.09(c).  In the event that a Servicer  shall  remit any amount not  required to be  remitted,  it
may at any time  withdraw  or direct  the  institution  maintaining  the  related  Collection  Account  to
withdraw   such  amount  from  such   Collection   Account,   any   provision   herein  to  the   contrary
notwithstanding.  Such withdrawal or direction may be  accomplished  by delivering  written notice thereof
to the Trustee or such other institution  maintaining such Collection  Account which describes the amounts
deposited  in error in such  Collection  Account.  Each  Servicer  shall  maintain  adequate  records with
respect  to  all  withdrawals  made  by it  pursuant  to  this  Section 3.05.  All  funds  deposited  in a
Collection  Account shall be held in trust for the  Certificateholders  until withdrawn in accordance with
Section 3.08(a).

(d)      On or prior to the Closing  Date,  the Trust  Administrator  shall  establish  and  maintain,  on
behalf of the  Certificateholders,  the  Certificate  Account.  The Trust  Administrator  shall,  promptly
upon receipt, deposit in the Certificate Account and retain therein the following:

         Non-Designated  Mortgage  Loans to the Trust  Administrator  and  (x) and  the  aggregate  amount
         remitted by each Designated  Servicer to the Master Servicer or Trust  Administrator  pursuant to
         their  respective  Designated  Servicing   Agreements,   in  each  case  including  any  Assigned
         Prepayment Premiums;

(ii)     any amount deposited by the Trust Administrator  pursuant to  Section 3.05(e) in  connection with
         any losses on Eligible Investments;

(v)      any other  amounts  deposited  hereunder  which are required to be  deposited in the  Certificate
         Account.

                  In the  event  that  the  Master  Servicer  or a  Servicer  shall  remit  to  the  Trust
Administrator  any  amount  not  required  to be  remitted,  the  Master  Servicer  or such  Servicer,  as
applicable,  may at any time direct the Trust  Administrator  to withdraw such amount from the Certificate
Account,  any provision  herein to the contrary  notwithstanding.  Such direction may be  accomplished  by
delivering an Officer's  Certificate to the Trust  Administrator  which describes the amounts deposited in
error in the Certificate  Account.  All funds  deposited in the  Certificate  Account shall be held by the
Trust  Administrator  in  trust  for the  Certificateholders  until  disbursed  in  accordance  with  this
Agreement or withdrawn  in  accordance  with  Section 3.08(b).  In no event shall the Trust  Administrator
incur  liability for withdrawals  from the Certificate  Account at the direction of the Master Servicer or
any Servicer.

(e)      Each  institution at which a Collection  Account or the Certificate  Account is maintained  shall
either hold such funds on deposit  uninvested  or shall invest the funds therein as directed in writing by
the related Servicer,  the Trust Administrator or the Depositor,  respectively,  in Eligible  Investments,
which shall mature not later than (i) in the case of a Collection  Account,  the Cash  Remittance Date and
(ii) in the case of the  Certificate  Account,  the Business Day  immediately  preceding the  Distribution
Date, or on the  Distribution  Date,  with respect to Eligible  Investments  invested with an affiliate of
the Trust  Administrator.  All  income  and gain net of any  losses  realized  from any such  balances  or
investment of funds on deposit in a Collection  Account  shall be for the benefit of the related  Servicer
as  servicing  compensation  and shall be  remitted to it monthly as  provided  herein.  The amount of any
realized losses in a Collection  Account  incurred in any such account in respect of any such  investments
shall  promptly be  deposited  by the  related  Servicer  (from its own funds) in the  related  Collection
Account.  Neither  the  Trustee  nor the Trust  Administrator  shall be liable  for the amount of any loss
incurred in respect of any  investment  or lack of  investment  of funds held in a Collection  Account and
made in accordance  with this  Section 3.05.  All income and gain net of any losses realized from any such
investment  of  funds  on  deposit  in the  Certificate  Account  shall be for the  benefit  of the  Trust
Administrator as compensation  and shall be remitted to it monthly as provided  herein.  The amount of any
realized  losses  in the  Certificate  Account  incurred  in any  such  account  in  respect  of any  such
investments  shall  promptly  be  deposited  by the  Trust  Administrator  (from  its  own  funds)  in the
Certificate Account.

(f)      Each  Servicer,   other  than  Wells  Fargo,  shall  give  notice  to  the  Trustee,   the  Trust
Administrator,  the Seller,  each Rating Agency and the  Depositor of any proposed  change of the location
of the  related  Collection  Account  prior to any change  thereof.  Wells  Fargo shall give notice to the
Depositor of any proposed  change of the location of the related  Collection  Account  prior to any change
thereof and,  upon  receipt of such  notice,  the  Depositor  shall give notice to the Trustee,  the Trust
Administrator,  the  Seller and each  Rating  Agency.  The Trust  Administrator  shall give  notice to the
Master Servicer and each Servicer,  the Seller,  each Rating Agency,  the Trustee and the Depositor of any
proposed change of the location of the Certificate Account prior to any change thereof.

payment of such charges  (including  renewal  premiums)  and shall effect or cause to be effected  payment

                  Each  Servicer  shall  keep  and  maintain  separate  accounting,  on  a  Non-Designated
Mortgage  Loan by Mortgage  Loan basis,  for the purpose of  justifying  any  withdrawal  from the related
Collection  Account  pursuant to such subclauses  (i), (ii),  (iv) and (v). Prior to making any withdrawal

indicating  the amount of any previous  Advance or Servicing  Advance  determined by such Servicer to be a
Nonrecoverable  Advance  and  identifying  the  related   Non-Designated   Mortgage  Loans(s),  and  their
respective  portions of such  Nonrecoverable  Advance. In connection with the payment of a Purchase Price,
if a Servicer is not required to remit  unreimbursed  Advances and Servicing  Advances as specified in the
definition of Purchase Price, such Servicer shall be deemed to have been reimbursed for such amount.

                  If  a  Servicer  fails  to  remit  to  the  Master  Servicer  for  distribution  to  the
Certificateholders  any payment,  including  any Advance to be made by the  Servicer on a Cash  Remittance
Date  (without  regard to any grace  period),  the  Servicer  shall pay to the  Master  Servicer,  for the
account of the Master  Servicer,  interest on such late  remittance from and including the Cash Remittance
Date to but  excluding  the date on which such  remittance is made, at an annual rate equal to the Federal
Funds Rate plus one percentage point (but in no event greater than the maximum permitted by law).

(b)      The Trust  Administrator  shall withdraw funds from the Certificate  Account for distributions to
Certificateholders,  in the manner  specified  in this  Agreement  (and to  withhold  from the  amounts so
withdrawn,  the amount of any taxes that it is  authorized  to  withhold  pursuant  to  Section 2.07).  In

(i)      to pay to itself any investment  income earned for the related  Distribution  Date, and to pay to
         itself or the Master  Servicer any other  amounts to which it or the Master  Servicer is entitled
         to reimbursement or payment under the terms of this Agreement;

(ii)     to withdraw  and return to the Master  Servicer  or the  applicable  Servicer  for deposit to the

         to be deposited therein; and

(iii)    to clear and terminate the  Certificate  Account upon  termination  of the Agreement  pursuant to
         Section 11.01 hereof.

SECTION 3.09.     Maintenance of Hazard Insurance; Mortgage Impairment Insurance and Mortgage Guaranty
                                            Insurance Policy; Claims; Restoration of Mortgaged Property.

(a)      Each Servicer shall cause to be maintained for each related  Non-Designated  Mortgage Loan hazard
insurance  such that all  buildings  upon the  related  Mortgaged  Property  are  insured  by a  generally
acceptable  insurer  rated  either:  "V" or better in the current  Best's Key Rating Guide  ("Best's")  or
acceptable to FNMA or FHLMC against loss by fire,  hazards of extended  coverage and such other hazards as
are  customary  in the area where the related  Mortgaged  Property is  located,  in an amount  which is at
least equal to the lesser of (i) the  replacement value of the improvements  securing such  Non-Designated
Mortgage  Loan and  (ii) the  greater of (A) the  outstanding  principal  balance  of such  Non-Designated
Mortgage  Loan and (B) an amount such that the proceeds of such policy shall be  sufficient to prevent the
Mortgagor and/or the mortgagee from becoming a co insurer.

                  If  upon  origination  of  the  Non-Designated  Mortgage  Loan,  the  related  Mortgaged
Property was located in an area  identified in the Federal  Register by the Federal  Emergency  Management
Agency as having  special flood hazards (and such flood  insurance has been made  available),  the related
Servicer  shall  cause a flood  insurance  policy to be  maintained  with  respect to such  Non-Designated
Mortgage  Loan.  Such  policy  shall  meet the  requirements  of the  current  guidelines  of the  Federal
Insurance  Administration  and be in an  amount  representing  coverage  equal to the  lesser  of  (i) the
minimum  amount  required,  under  the  terms of  coverage,  to  compensate  for any  damage  or loss on a
replacement  cost basis (or the unpaid  principal  balance of the mortgage if replacement cost coverage is
not  available  for the type of building  insured)  and  (ii) the  maximum  amount of  insurance  which is
available under the Flood Disaster Protection Act of 1973, as amended.

                  If a  Mortgage  related  to a  Non-Designated  Mortgage  Loan is  secured by a unit in a
condominium  project,  the  related  Servicer  shall  verify  that the  coverage  required  of the owner's
association,   including  hazard,  flood,  liability,  and  fidelity  coverage,  is  being  maintained  in
accordance with the  requirements  of the related  Servicer for mortgage loans that it services on its own
account.

                  Each  Servicer  shall cause to be  maintained on each  Mortgaged  Property  related to a
Non-Designated  Mortgage Loan such other additional  special hazard insurance as may be required  pursuant
to such  applicable  laws and  regulations  as shall at any  time be in force  and as shall  require  such
additional  insurance,  or pursuant to the requirements of any Mortgage Guaranty Insurance Policy insurer,
or as may be  required  to conform  with  Accepted  Servicing  Practices  to the extent  permitted  by the
Mortgage  Note,  the Mortgage or applicable  law provided that the related  Servicer shall not be required
to bear the cost of such insurance.

                  All  policies  required  hereunder  shall name the  related  Servicer  as loss payee and
shall be endorsed with standard or union  mortgagee  clauses,  without  contribution,  which shall provide
for prior written notice of any cancellation, reduction in amount or material change in coverage.

                  Each  Servicer  shall  not  interfere  with the  Mortgagor's  freedom  of  choice at the
origination  of such  Non-Designated  Mortgage Loan in selecting  either his  insurance  carrier or agent,
provided,  however,  that such  Servicer  shall not  accept any such  insurance  policies  from  insurance
companies  unless such  companies are rated:  B:III or better in Best's or acceptable to FNMA or FHLMC and
are licensed to do business in the  jurisdiction in which the Mortgaged  Property is located.  The related
Servicer  shall  determine  that such policies  provide  sufficient  risk coverage and amounts,  that they
insure the property owner, and that they properly describe the property address.

                  Pursuant to  Section 3.05,  any amounts  collected by a Servicer under any such policies
(other than  amounts to be  deposited  in the related  Escrow  Account and applied to the  restoration  or
repair of the related  Mortgaged  Property,  or property  acquired in  liquidation  of the  Non-Designated
Mortgage Loan, or to be released to the Mortgagor,  in accordance  with such Servicer's  normal  servicing
procedures)  shall be deposited  in the related  Collection  Account  (subject to  withdrawal  pursuant to
Section 3.08(a)).

                  Any cost incurred by a Servicer in  maintaining  any such  insurance  shall not, for the
purpose of  calculating  monthly  distributions  to the  Certificateholders  or  remittances  to the Trust
Administrator for their benefit,  be added to the principal balance of the  Non-Designated  Mortgage Loan,
notwithstanding  that the terms of the Non-Designated  Mortgage Loan so permit;  provided,  however,  that
the  limitations   contained  in  this  sentence  shall  not  apply  to  modifications  made  pursuant  to
Section 3.05(a).  Such costs shall constitute a Servicing  Advance and will be reimbursable to the related
Servicer to the extent  permitted by Section 3.08  hereof.  It is understood and agreed that no earthquake
or other  additional  insurance is to be required of any Mortgagor  related to a  Non-Designated  Mortgage
Loan or  maintained on property  acquired in respect of a Mortgage  related to a  Non-Designated  Mortgage
Loan other than pursuant to such  applicable  laws and regulations as shall at any time be in force and as
shall require such additional insurance.

(b)      In the event that a Servicer shall obtain and maintain a blanket policy  insuring  against losses
arising  from fire and hazards  covered  under  extended  coverage  on all of the  related  Non-Designated
Mortgage  Loans,  then,  to the extent such  policy  provides  coverage  in an amount  equal to the amount
required   pursuant  to   Section 3.09(a) and   otherwise   complies  with  all  other   requirements   of
Section 3.09(a),  it shall  conclusively  be  deemed to have  satisfied  its  obligations  as set forth in
Section 3.09(a).  Any amounts  collected by a Servicer under any such policy relating to a  Non-Designated
Mortgage  Loan shall be deposited in the related  Collection  Account  subject to  withdrawal  pursuant to
Section 3.08(a).  Such  policy may contain a  deductible  clause,  in which case,  in the event that there
shall  not  have  been   maintained  on  the  related   Mortgaged   Property  a  policy   complying   with
Section 3.09(a),  and there  shall have been a loss  which  would have been  covered by such  policy,  the
related Servicer shall deposit in the related  Collection  Account at the time of such loss the amount not
otherwise  payable  under  the  blanket  policy  because  of such  deductible  clause,  such  amount to be
deposited  from  such  Servicer's  funds,  without  reimbursement  therefor.  Upon  request  of the  Trust
Administrator,  a Servicer  shall cause to be delivered to the Trust  Administrator  a certified true copy
of such  policy  and a  statement  from the  insurer  thereunder  that  such  policy  shall in no event be
terminated or materially  modified  without 30 days' prior written notice to the Trust  Administrator.  In
connection with its activities as Servicer of the related  Non-Designated  Mortgage  Loans,  such Servicer
agrees to present,  on behalf of itself,  the Depositor,  and the Trust  Administrator  for the benefit of
the Certificateholders, claims under any such blanket policy.

(c)      With respect to each  Non-Designated  Mortgage Loan with a  Loan-to-Value  Ratio in excess of 80%
which the Seller  represented  to be covered by a Mortgage  Guaranty  Insurance  Policy as of the  Cut-off
Date, the related Servicer shall,  without any cost to the Depositor or Trust  Administrator,  maintain or
cause the Mortgagor to maintain in full force and effect a Mortgage  Guaranty  Insurance  Policy  insuring
that portion of the  Non-Designated  Mortgage Loan in excess of 75% of value, and shall pay or shall cause
the  Mortgagor  to pay,  the premium  thereon on a timely  basis,  until the  loan-to-value  ratio of such
Non-Designated  Mortgage Loan is reduced to 80%, based on either (i) a current  appraisal of the Mortgaged
Property  or  (ii) the  appraisal  of the  Mortgaged  Property  obtained  at the time  the  Non-Designated
Mortgage  Loan was  originated.  In the event  that  such  Mortgage  Guaranty  Insurance  Policy  shall be
terminated prior to the  loan-to-value  ratio of such  Non-Designated  Mortgage Loan being reduced to 80%,
the related Servicer shall obtain from another Qualified Insurer a comparable  replacement  policy, with a
total coverage equal to the remaining  coverage of such terminated  Mortgage Guaranty Insurance Policy. If
the  insurer  shall  cease to be a  Qualified  Insurer,  the  related  Servicer  shall  determine  whether
recoveries  under the  Mortgage  Guaranty  Insurance  Policy are  jeopardized  for reasons  related to the
financial  condition of such insurer,  it being  understood  that such Servicer shall in no event have any
responsibility  or liability for any failure to recover under the Mortgage  Guaranty  Insurance Policy for
such reason.  If the related Servicer  determines that recoveries are so jeopardized,  it shall notify the
Mortgagor,  if required,  and obtain from another  Qualified Insurer a replacement  insurance policy.  The
related  Servicer  shall not take any  action  which  would  result in  noncoverage  under any  applicable
Mortgage  Guaranty  Insurance  Policy of any loss which,  but for the actions of such Servicer  would have
been covered  thereunder.  In connection with any assumption or substitution  agreement entered into or to
be entered into  pursuant to  Section 3.10,  each  Servicer  shall  promptly  notify the insurer under the
related Mortgage  Guaranty  Insurance  Policy,  if any, of such assumption or substitution of liability in
accordance  with the terms of such  Mortgage  Guaranty  Insurance  Policy and shall take all actions which
may be required by such  insurer as a  condition  to the  continuation  of  coverage  under such  Mortgage
Guaranty  Insurance  Policy,  provided that such required  actions are in compliance  with all  applicable
law.  If such  Mortgage  Guaranty  Insurance  Policy  is  terminated  as a result  of such  assumption  or
substitution of liability,  the related Servicer shall obtain a replacement  Mortgage  Guaranty  Insurance
Policy as provided above;  provided that under  applicable law and the terms of the related  Mortgage Note
and Mortgage the cost of such policy may be charged to the successor Mortgagor.

                  With respect to each  Non-Designated  Mortgage  Loan  covered by a Lender Paid  Mortgage
Guaranty  Insurance  Policy,  the applicable  Servicer shall effect timely payment of the premiums on such
Mortgage  Guaranty  Insurance  Policy from amounts on deposit in the  Collection  Account,  or deducted by
such Servicer prior to deposit into the applicable  Collection  Account  pursuant to  Section 3.05(c) with
respect to such  Non-Designated  Mortgage  Loan.  If amounts on  deposit  in the  Collection  Account,  or
deducted  by  such  Servicer  prior  to  deposit  into  the  applicable  Collection  Account  pursuant  to
Section 3.05(c) with  respect to such Non-Designated  Mortgage Loan are not sufficient to pay the premiums
on such Mortgage Guaranty  Insurance Policy,  the applicable  Servicer shall effect timely payment of such
premiums,  and such costs shall be recoverable by such Servicer from the related  Liquidation  Proceeds or
otherwise  as a  Servicing  Advance  pursuant  to  Section 3.08(a).  With  respect to each  Non-Designated
Mortgage  Loan  covered  by a  Mortgage  Guaranty  Insurance  Policy  that is not a Lender  Paid  Mortgage
Guaranty  Insurance  Policy,  the applicable  Servicer shall effect timely payment of the premiums on such
Mortgage Guaranty Insurance Policy,  and such costs not otherwise  recoverable from the Mortgagor shall be
recoverable  by such Servicer from the related  Liquidation  Proceeds or otherwise as a Servicing  Advance
pursuant to Section 3.08(a).

(d)      In connection  with its  activities  as servicer,  each  Servicer  shall prepare and present,  on
behalf  of  itself,   the  Depositor,   the  Trust,  the  Trustee,   the  Trust   Administrator   and  the
Certificateholders,  claims to the insurer  under any  Mortgage  Guaranty  Insurance  Policy  related to a
Non-Designated  Mortgage Loan in a timely fashion in accordance  with the terms of such Mortgage  Guaranty
Insurance  Policy and, in this  regard,  to take such  reasonable  action as shall be  necessary to permit
recovery  under any Mortgage  Guaranty  Insurance  Policy  respecting  defaulted  Non-Designated  Mortgage
Loans.  Pursuant  to  Section 3.05,  any  amounts  collected  by a Servicer  under any  Mortgage  Guaranty
Insurance Policy shall be deposited in the related Collection  Account,  subject to withdrawal pursuant to
Section 3.08.

(e)      With respect to any  Non-Designated  Mortgage Loan, each Servicer need not obtain the approval of
the  Trustee  or the  Trust  Administrator  prior to  releasing  any  Insurance  Proceeds  to the  related
Mortgagor to be applied to the  restoration  or repair of the related  Mortgaged  Property if such release
is in accordance  with Accepted  Servicing  Practices.  At a minimum,  each Servicer shall comply with the
following conditions in connection with any such release of Insurance Proceeds:

(i)      such Servicer shall receive  satisfactory  independent  verification of completion of repairs and
         issuance of any required approvals with respect thereto;

(ii)     such  Servicer  shall  take all steps  necessary  to  preserve  the  priority  of the lien of the
         Mortgage,  including,  but not  limited to  requiring  waivers  with  respect to  mechanics'  and
         materialmen's liens; and

(iii)    pending repairs or restoration,  such Servicer shall place the Insurance  Proceeds in the related
         Escrow Account.

(f)      With respect to any  Non-Designated  Mortgage  Loan,  if the Trust  Administrator  is named as an
additional  loss payee,  the  related  Servicer is hereby  empowered  to endorse any loss draft  issued in
respect of such a claim in the name of the Trustee or the Trust Administrator.

SECTION 3.10.     Enforcement of Due on Sale Clauses; Assumption Agreements.

(a)      With respect to any  Non-Designated  Mortgage  Loan,  each Servicer shall use its best efforts to
enforce  any  "due-on-sale"  provision  contained  in any related  Mortgage  or Mortgage  Note and to deny
assumption  by the  person  to whom the  Mortgaged  Property  has been or is about to be sold  whether  by
absolute  conveyance  or by  contract  of sale,  and whether or not the  Mortgagor  remains  liable on the
Mortgage and the Mortgage  Note.  When the  Mortgaged  Property has been  conveyed by the  Mortgagor,  the
related  Servicer  shall,  to the  extent it has  knowledge  of such  conveyance,  exercise  its rights to
accelerate the maturity of such  Non-Designated  Mortgage Loan under the  "due-on-sale"  clause applicable
thereto,  provided,  however,  that such Servicer shall not exercise such rights if prohibited by law from
doing so or if the  exercise of such rights  would  impair or  threaten to impair any  recovery  under the
related Mortgage Guaranty Insurance Policy, if any.

(b)      With  respect to any  Non-Designated  Mortgage  Loan,  if a Servicer  reasonably  believes  it is
unable under applicable law to enforce such  "due-on-sale"  clause,  such Servicer shall enter into (i) an
assumption and  modification  agreement with the person to whom such property has been conveyed,  pursuant
to which such person  becomes  liable under the Mortgage Note and the original  Mortgagor  remains  liable
thereon or (ii) in the event such  Servicer is unable  under  applicable  law to require that the original
Mortgagor  remain  liable  under the  Mortgage  Note,  a  substitution  of  liability  agreement  with the
purchaser of the Mortgaged  Property  pursuant to which the original  Mortgagor is released from liability
and the  purchaser of the Mortgaged  Property is  substituted  as Mortgagor  and becomes  liable under the
Mortgage Note.  Notwithstanding the foregoing,  a Servicer shall not be deemed to be in default under this
Section 3.10 by  reason of any  transfer  or  assumption  which such  Servicer  reasonably  believes it is
restricted by law from preventing,  for any reason whatsoever.  In connection with any such assumption, no
material term of the Mortgage Note,  including without limitation,  the Mortgage Rate borne by the related
Mortgage Note, the term of the  Non-Designated  Mortgage Loan or the outstanding  principal  amount of the
Non-Designated Mortgage Loan shall be changed.

(c)      To the extent that any  Non-Designated  Mortgage Loan is assumable,  the related  Servicer  shall
inquire diligently into the  creditworthiness of the proposed  transferee,  and shall use the underwriting
criteria  for  approving  the credit of the  proposed  transferee  which are used by FNMA with  respect to
underwriting  mortgage loans of the same type as the  Non-Designated  Mortgage Loans. If the credit of the
proposed  transferee does not meet such underwriting  criteria,  the related Servicer diligently shall, to
the extent  permitted by the Mortgage or the Mortgage Note and by applicable law,  accelerate the maturity
of the Non-Designated Mortgage Loan.

(d)      With respect to any  Non-Designated  Mortgage Loan,  subject to each  Servicer's  duty to enforce
any  due-on-sale  clause to the extent set forth in this  Section 3.10,  in any case in which the  related
Mortgaged  Property has been  conveyed to a Person by the related  Mortgagor,  and such Person is to enter
into an  assumption  agreement or  modification  agreement or  supplement to the Mortgage Note or Mortgage
that  requires the  signature  of the Trustee,  or if an  instrument  of release  signed by the Trustee is
required releasing the Mortgagor from liability on the  Non-Designated  Mortgage Loan, such Servicer shall
prepare and deliver or cause to be prepared and  delivered to the Trustee for  signature and shall direct,
in  writing,  the  Trustee to  execute  the  assumption  agreement  with the Person to whom the  Mortgaged
Property  is to be  conveyed  and such  modification  agreement  or  supplement  to the  Mortgage  Note or
Mortgage or other  instruments  as are reasonable or necessary to carry out the terms of the Mortgage Note
or Mortgage or otherwise to comply with any applicable  laws regarding  assumptions or the transfer of the
Mortgaged  Property to such  Person.  In  connection  with any such  assumption,  no material  term of the
Mortgage Note may be changed.  Together  with each such  substitution,  assumption  or other  agreement or
instrument  delivered to the Trustee for execution by it, the related  Servicer shall deliver an Officer's
Certificate  signed by a Servicing  Officer stating that the requirements of this subsection have been met
in connection  therewith.  The related Servicer shall notify the Trustee and the Trust  Administrator that
any such  substitution  or assumption  agreement  has been  completed by forwarding to the Trustee and the
Trust  Administrator a copy of such substitution or assumption  agreement,  and shall forward the original
to the related  Custodian which shall be added to the related  Mortgage File and shall,  for all purposes,
be  considered a part of such  Mortgage  File to the same extent as all other  documents  and  instruments
constituting  a part  thereof.  Any fee  collected  by a  Servicer  for  entering  into an  assumption  or
substitution  of  liability  agreement  shall  be  retained  by  such  Servicer  as  additional  servicing
compensation.

SECTION 3.11.     Realization Upon Defaulted Mortgage Loans; Repurchase of Certain Mortgage Loans.

(a)      Each Servicer shall use  reasonable  efforts to foreclose  upon or otherwise  comparably  convert
the ownership of properties  securing such of the related  Non-Designated  Mortgage Loans as come into and
continue  in  default  and as to  which  no  satisfactory  arrangements  can be  made  for  collection  of
delinquent  payments.  In connection with such foreclosure or other  conversion,  each Servicer shall take
such  action as  (i) such  Servicer  would  take under  similar  circumstances  with  respect to a similar
mortgage loan held for its own account for investment,  (ii) shall be consistent  with Accepted  Servicing
Practices,  (iii) such  Servicer shall determine  consistently with Accepted Servicing  Practices to be in
the best interest of the Trust and  Certificateholders,  and (iv) is  consistent with the  requirements of
the insurer under any Required  Insurance  Policy;  provided,  however,  that such  Servicer  shall not be
required to expend its own funds in connection  with any  foreclosure  or towards the  restoration  of any
property  unless it shall  determine  (i) that  such  restoration  and/or  foreclosure  will  increase the
proceeds of  liquidation  of the related  Non-Designated  Mortgage Loan after  reimbursement  to itself of
such expenses and (ii) that  such expenses will be  recoverable to it through  Liquidation  Proceeds.  Any
funds expended by any Servicer  pursuant to this  Section 3.11(a) shall  be  reimbursable in full pursuant
to  Section 3.08(a)(iii).  The related  Servicer  shall be  responsible  for all other costs and  expenses
incurred by it in any such  proceedings;  provided,  however,  that it shall be entitled to  reimbursement
thereof from the  Liquidation  Proceeds with respect to the related  Mortgaged  Property or otherwise as a
Servicing Advance in accordance with Section 3.08(a).

                  With  respect to any  Non-Designated  Mortgage  Loan,  notwithstanding  anything  to the
contrary  contained in this  Agreement,  in connection  with a foreclosure or acceptance of a deed in lieu
of  foreclosure,  in the event the  related  Servicer  has  reasonable  cause to believe  that the related
Mortgaged  Property  is  contaminated  by  hazardous  or  toxic  substances  or  wastes,  or if the  Trust
Administrator  otherwise  requests,  an  environmental  inspection  or review of such  Mortgaged  Property
conducted  by a qualified  inspector  shall be  arranged  for by such  Servicer.  Upon  completion  of the
inspection,  the related Servicer shall promptly provide the Trust  Administrator with a written report of
environmental inspection.

                  In the event the environmental  inspection report indicates that the Mortgaged  Property
is contaminated by hazardous or toxic  substances or wastes,  the related  Servicer shall not proceed with
foreclosure  or acceptance of a deed in lieu of foreclosure  if the estimated  costs of the  environmental
clean up, as estimated in the environmental  inspection  report,  together with the Servicing Advances and
Advances made by such Servicer and the estimated  costs of  foreclosure or acceptance of a deed in lieu of
foreclosure  exceeds the estimated  value of the  Mortgaged  Property.  If however,  the aggregate of such
clean up and foreclosure  costs,  Advances and Servicing  Advances are less than or equal to the estimated
value of the  Mortgaged  Property,  then the related  Servicer  may,  in its  reasonable  judgment  and in
accordance with Accepted Servicing  Practices,  choose to proceed with foreclosure or acceptance of a deed
in lieu of foreclosure  and such Servicer shall be reimbursed for all  reasonable  costs  associated  with
such  foreclosure or acceptance of a deed in lieu of foreclosure  and any related  environmental  clean up
costs,  as  applicable,  from  the  related  Liquidation  Proceeds,  or if the  Liquidation  Proceeds  are
insufficient  to fully  reimburse  such Servicer,  such Servicer  shall be entitled to be reimbursed  from
amounts in the related  Collection  Account pursuant to  Section 3.08(a) hereof.  In the event the related
Servicer does not proceed with  foreclosure  or acceptance  of a deed in lieu of  foreclosure  pursuant to
the first  sentence of this  paragraph,  such Servicer  shall be reimbursed for all Advances and Servicing
Advances  made with  respect  to the  related  Mortgaged  Property  from the  related  Collection  Account
pursuant to  Section 3.08(a) hereof,  and such Servicer  shall have no further  obligation to service such
Non-Designated Mortgage Loan under the provisions of this Agreement.

(b)      With  respect  to any  REO Property  related  to a  Non-Designated  Mortgage  Loan,  the  deed or
certificate  of sale  shall,  subject to  applicable  laws,  be taken in the name of the  Trustee  for the
benefit of the  Certificateholders,  or its nominee,  on behalf of the  Certificateholders.  The Trustee's
name shall be placed on the title to such  REO Property  solely as the  Trustee  hereunder  and not in its
individual  capacity.  The related  Servicer shall ensure that the title to such  REO Property  references
this  Agreement and the Trustee  capacity  hereunder.  Pursuant to its efforts to sell such  REO Property,
the related Servicer shall in accordance with Accepted Servicing Practices manage,  conserve,  protect and
operate  each  REO Property  for the purpose of its prompt  disposition  and sale.  The related  Servicer,
either itself or through an agent selected by such Servicer, shall manage,  conserve,  protect and operate
the  REO Property in the same manner that it manages,  conserves,  protects and operates other  foreclosed
property for its own account,  and in the same manner that  similar  property in the same  locality as the
REO Property is managed.  Upon request,  the related Servicer shall furnish to the Trust  Administrator on
or before each  Distribution  Date a statement with respect to any REO Property  covering the operation of
such  REO Property  for the previous  calendar month and such  Servicer's  efforts in connection  with the
sale of such  REO Property  and any rental of such  REO Property  incidental  to the sale  thereof for the
previous  calendar  month.  That statement  shall be  accompanied  by such other  information as the Trust
Administrator  shall  reasonably  request  and which is  necessary  to enable the Trust  Administrator  to
comply with the reporting  requirements of the REMIC  Provisions.  The net monthly rental income,  if any,
from such  REO Property  shall be deposited in the related  Collection  Account no later than the close of
business  on  each  Determination  Date.  The  related  Servicer  shall  perform  the  tax  reporting  and
withholding  required  by  Sections  1445  and  6050J  of  the  Code  with  respect  to  foreclosures  and
abandonments,  the tax  reporting  required by  Section 6050H  of the Code with  respect to the receipt of
mortgage  interest from  individuals  and any tax  reporting  required by  Section 6050P  of the Code with
respect to the  cancellation  of  indebtedness by certain  financial  entities,  by preparing such tax and
information  returns  as may be  required,  in the form  required,  and  delivering  the same to the Trust
Administrator for filing.

                  To the extent consistent with Accepted Servicing  Practices,  the related Servicer shall
also maintain on each  REO Property  related to a  Non-Designated  Mortgage Loan fire and hazard insurance
with extended  coverage in an amount which is equal to the  outstanding  principal  balance of the related
Non-Designated  Mortgage  Loan (as reduced by any amount  applied as a reduction  of principal at the time
of acquisition of the REO Property),  liability  insurance and, to the extent required and available under
the Flood Disaster Protection Act of 1973, as amended, flood insurance in the amount required above.

(c)      In the event that the Trust Fund  acquires  any  Mortgaged  Property as aforesaid or otherwise in
connection  with a default or imminent  default on a Mortgage Loan, the related  Servicer shall dispose of
such  Mortgaged  Property  prior to three years after the end of the calendar year of its  acquisition  by
the Trust Fund  unless  (i) the  Trustee  and the Trust  Administrator  shall have been  supplied  with an
Opinion  of  Counsel  to the  effect  that  the  holding  by the  Trust  Fund of such  Mortgaged  Property
subsequent  to such  three-year  period  will  not  result  in the  imposition  of  taxes  on  "prohibited
transactions"  of any REMIC  hereunder as defined in section 860F of the Code or cause any REMIC hereunder
to fail to qualify as a REMIC at any time that any Certificates  are outstanding,  in which case the Trust
Fund may continue to hold such Mortgaged  Property  (subject to any  conditions  contained in such Opinion
of Counsel) or (ii) the  applicable  Servicer  shall have applied  for,  prior to the  expiration  of such
three-year period, an extension of such three-year period in the manner contemplated by  Section 856(e)(3)
of the Code, in which case the  three-year  period shall be extended by the applicable  extension  period.
Notwithstanding  any other provision of this Agreement,  no Mortgaged  Property acquired by the Trust Fund
shall be rented (or allowed to continue to be rented) or otherwise  used for the  production  of income by
or on behalf of the Trust  Fund in such a manner or  pursuant  to any  terms  that  would  (i) cause  such
Mortgaged  Property to fail to qualify as "foreclosure  property" within the meaning of section 860G(a)(8)
of the Code or (ii) subject  any REMIC  hereunder to the imposition of any federal,  state or local income
taxes on the income earned from such Mortgaged  Property under  Section 860G(c) of  the Code or otherwise,
unless the related  Servicer has agreed to indemnify  and hold harmless the Trust Fund with respect to the
imposition of any such taxes.

                  In the event of a default  on a  Mortgage  Loan one or more of whose  obligors  is not a
United States Person, as that term is defined in  Section 7701(a)(30)  of the Code, in connection with any
foreclosure or acquisition of a deed in lieu of foreclosure  (together,  "foreclosure") in respect of such
Mortgage Loan,  the related  Servicer shall cause  compliance  with the provisions of Treasury  Regulation
Section 1.1445-2(d)(3)  (or any successor  thereto) necessary to assure that no withholding tax obligation
arises with respect to the proceeds of such  foreclosure  except to the extent,  if any,  that proceeds of
such foreclosure are required to be remitted to the obligors on such Mortgage Loan.

(d)      The  decision of a Servicer to  foreclose on a defaulted  Non-Designated  Mortgage  Loan shall be
subject to a determination by such Servicer that the proceeds of such  foreclosure  would exceed the costs
and  expenses  of  bringing  such a  proceeding.  The  income  earned  from  the  management  of  any  REO
Properties,  net of reimbursement to such Servicer for expenses incurred  (including any property or other
taxes) in connection  with such  management and net of applicable  accrued and unpaid  Servicing Fees, and
unreimbursed  Advances  and  Servicing  Advances,  shall be applied to the  payment  of  principal  of and
interest on the related  defaulted  Non-Designated  Mortgage Loans (with interest  accruing as though such
Non-Designated  Mortgage Loans were still  current) and all such income shall be deemed,  for all purposes
in this Agreement,  to be payments on account of principal and interest on the related  Mortgage Notes and
shall be deposited  into the related  Collection  Account.  To the extent the net income  received  during
any calendar month is in excess of the amount  attributable to amortizing  principal and accrued  interest
at the related  Mortgage Rate on the related  Non-Designated  Mortgage Loan for such calendar month,  such
excess  shall be  considered  to be a  partial  prepayment  of  principal  of the  related  Non-Designated
Mortgage Loan.

(e)      The proceeds from any liquidation of a  Non-Designated  Mortgage Loan, as well as any income from
a related  REO Property,  will be applied in the  following  order of priority:  first,  to reimburse  the
related Servicer for any related  unreimbursed  Servicing Advances and Servicing Fees, and with respect to
Wells Fargo,  any REO Disposition Fees related to such Mortgage Loan;  second,  to reimburse such Servicer
for any unreimbursed  Advances;  third, to reimburse the related Collection Account for any Nonrecoverable
Advances  (or  portions   thereof)  that  were   previously   withdrawn  by  such  Servicer   pursuant  to
Section 3.08(a)(iii) that  related to such  Non-Designated  Mortgage Loan;  fourth,  to accrued and unpaid
interest  (to the  extent  no  Advance  has been  made  for  such  amount  or any  such  Advance  has been
reimbursed) on the Non-Designated  Mortgage Loan or related  REO Property,  at the per annum rate equal to
the related  Mortgage Rate reduced by the related  Servicing Fee Rate, and any primary  mortgage  guaranty
insurance  fee rate,  if  applicable,  to the Due Date  occurring  in the month in which such  amounts are
required  to be  distributed;  and  fifth,  as a  recovery  of  principal  of the  Mortgage  Loan.  Excess
proceeds,  if any, from the  liquidation  of a Liquidated  Mortgage Loan and/or with respect to recoveries
obtained  following  the  liquidation  of  a  Liquidated  Mortgage  Loan  ("Excess  Proceeds")  that  is a
Non-Designated  Mortgage  Loan  shall  be  retained  by  the  related  Servicer  as  additional  servicing
compensation pursuant to Section 3.14.

(f)      With respect to any Mortgage  Loan related to the  Group 1,  Group 2 or Group 3  Certificates,  a
Servicer of such  Mortgage Loan may (but is not  obligated  to) enter into a special  servicing  agreement
with an  unaffiliated  Holder of a 100%  Percentage  Interest  of the most  junior  outstanding  Class C-B
Certificates.  Any such  agreement  may  contain  provisions  whereby  such  Holder may  (i) instruct  the
related  Servicer to commence or delay  foreclosure  proceedings  with respect to any such  Mortgage  Loan
that is delinquent  and will contain  provisions for the deposit of cash with such Servicer by such Holder
that would be available for  distribution  to  Certificateholders  if  Liquidation  Proceeds are less than
they  otherwise  may  have  been had  such  Servicer  acted in  accordance  with  its  normal  procedures,
(ii) purchase  any such  Mortgage  Loan that is delinquent  from the Trust Fund  immediately  prior to the
commencement of foreclosure  proceedings at a price equal to the Purchase Price,  and/or  (iii) assume all
of the  servicing  rights and  obligations  (as a  Sub-Servicer  on behalf of the related  Servicer)  with
respect to any such Mortgage  Loan that is  delinquent  so long as (A) such Holder meets the  requirements
for a Sub-Servicer set forth in  Section 3.02(a),  (B) such Holder has a current special servicing ranking
of at least  "Average" from S&P, (C) such Holder shall  subservice  such Mortgage Loan in accordance  with
this Agreement,  and (D) the related  Servicer has the right to transfer such servicing rights without the
payment of any compensation to a Sub-Servicer.

                  With respect to any Mortgage  Loan  related to the Group 4  Certificates,  a Servicer of
such  Mortgage  Loan may (but is not  obligated  to) enter  into a  special  servicing  agreement  with an
unaffiliated  Holder of a 100% Percentage Interest of the Class 4-X  Certificates.  Any such agreement may
contain  provisions  whereby  such  Holder may  (i) instruct  the  related  Servicer  to commence or delay
foreclosure  proceedings  with  respect to any such  Mortgage  Loan that is  delinquent  and will  contain
provisions  for the  deposit  of cash with such  Servicer  by such  Holder  that  would be  available  for
distribution  to  Certificateholders  if  Liquidation  Proceeds are less than they otherwise may have been
had such Servicer acted in accordance  with its normal  procedures,  (ii) purchase  any such Mortgage Loan
that is delinquent from the Trust Fund immediately  prior to the  commencement of foreclosure  proceedings
at a price equal to the Purchase Price,  and/or  (iii) assume  all of the servicing rights and obligations
(as a  Sub-Servicer  on behalf of the related  Servicer)  with respect to any such  Mortgage  Loan that is
delinquent  so  long  as  (A) such  Holder  meets  the  requirements  for  a  Sub-Servicer  set  forth  in
Section 3.02(a),  (B) such Holder has a current special  servicing ranking of at least "Average" from S&P,
(C) such Holder shall  subservice  such  Mortgage  Loan in  accordance  with this  Agreement,  and (D) the
related  Servicer has the right to transfer such servicing  rights without the payment of any compensation
to a Sub-Servicer.

(g)      The Special  Servicer,  at its option,  may (but is not  obligated  to)  purchase  from the Trust
Fund,  (a) any  Mortgage Loan that is delinquent  in payment 90 or more days or (b) any  related  Mortgage
Loan  with  respect  to  which  there  has been  initiated  legal  action  or  other  proceedings  for the
foreclosure  of the  related  Mortgaged  Property  either  judicially  or  non-judicially,  in each  case,
provided that the applicable  Servicer has the right to transfer the related  servicing rights without the
payment of any  compensation  to a  Sub-Servicer.  In the event that the Special  Servicer  exercises such
option,  the Purchase Price therefor  shall be deposited in the related  Collection  Account and upon such
deposit of the Purchase  Price and receipt of a Request for Release in the form of Exhibit K  hereto,  the
Custodian shall release the related  Mortgage File held for the benefit of the  Certificateholders  to the
Special  Servicer,  and the Trustee shall  execute and deliver at the Special  Servicer's  direction  such
instruments of transfer or assignment  prepared by the Special  Servicer,  in each case without  recourse,
as shall be  necessary  to  transfer  title  from the  Trustee to the  Special  Servicer.  The  applicable
Servicer shall be entitled to reimbursement  from the Special Servicer for all expenses  incurred by it in
connection  with  the  transfer  of  any  Mortgage  Loan  to  the  Special   Servicer   pursuant  to  this
Section 3.11(g).

SECTION 3.12.     Trustee and Trust Administrator to Cooperate; Release of Mortgage Files.

                  Upon the  payment  in full of any  Non-Designated  Mortgage  Loan,  or the  receipt by a
Servicer  of a  notification  that  payment  in full  will be  escrowed  in a  manner  customary  for such
purposes,  such Servicer shall immediately  notify the related  Custodian by delivering,  or causing to be
delivered a "Request for Release"  substantially  in the form of Exhibit K.  Upon receipt of such request,
such  Custodian  shall  within  three  Business  Days  release  the related  Mortgage  File to the related
Servicer,  and the Trustee  shall within three  Business  Days of such  Servicer's  direction  execute and
deliver to such  Servicer  the deed of  reconveyance  or  release  or  satisfaction  of  mortgage  or such
instrument  releasing the lien of the Mortgage in each case provided by such Servicer,  and such Custodian
shall  deliver the Mortgage  Note with written  evidence of  cancellation  thereon.  Expenses  incurred in
connection  with any  instrument  of  satisfaction  or deed of  reconveyance  shall be  chargeable  to the
related  Mortgagor.  From time to time and as shall be  appropriate  for the servicing or  foreclosure  of
any  Non-Designated  Mortgage  Loan,  including  for such  purpose,  collection  under any policy of flood
insurance,  any fidelity  bond or errors or omissions  policy,  or for the purposes of effecting a partial
release of any Mortgaged  Property from the lien of the Mortgage or the making of any  corrections  to the
Mortgage Note or the Mortgage or any of the other  documents  included in the Mortgage  File,  the related
Custodian  within three  Business Days of delivery to such  Custodian of a Request for Release in the form
of Exhibit K signed by a Servicing  Officer,  release the Mortgage File to the related  Servicer.  Subject
to the further  limitations  set forth  below,  the related  Servicer  shall  cause the  Mortgage  File or
documents  so released to be returned to the related  Custodian on its behalf,  when the need  therefor by
such Servicer no longer  exists,  unless the  Non-Designated  Mortgage Loan is liquidated and the proceeds
thereof are deposited in the related  Collection  Account,  in which case such  Servicer  shall deliver to
the  Trustee,  or the  related  Custodian  a Request  for  Release in the form of  Exhibit K,  signed by a
Servicing  Officer.  Each Servicer is also  authorized to cause the removal from the  registration  on the
MERS®  System  of  such  Mortgage  and  to  execute  and  deliver,  on  behalf  of  the  Trustee  and  the
Certificateholders  or any of them, any and all  instruments of satisfaction or cancellation or of partial
or full release, including an assignment of such loan to the Trustee.

                  If a Servicer at any time seeks to initiate a  foreclosure  proceeding in respect of any
Mortgaged  Property  related to a  Non-Designated  Mortgage  Loan as authorized  by this  Agreement,  such
Servicer shall deliver or cause to be delivered to the Trustee, for signature,  as appropriate,  any court
pleadings,  requests for trustee's sale or other  documents  necessary to effectuate  such  foreclosure or
any legal action  brought to obtain  judgment  against the  Mortgagor on the Mortgage Note or the Mortgage
or to obtain a  deficiency  judgment or to enforce any other  remedies or rights  provided by the Mortgage
Note or the Mortgage or otherwise available at law or in equity.

SECTION 3.13.     Documents, Records and Funds in Possession of a Servicer to be Held for the Trust.

                  Notwithstanding  any other  provisions of this  Agreement,  each Servicer shall transmit
to the related  Custodian,  as required by this  Agreement all documents and  instruments  in respect of a
Non-Designated  Mortgage  Loan  coming  into the  possession  of the  related  Servicer  from time to time
required to be  delivered to the Trustee,  or such  Custodian on its behalf,  pursuant to the terms hereof
and shall  account  fully to the Trust  Administrator  for any funds  received  by such  Servicer or which
otherwise are collected by such Servicer as Liquidation  Proceeds or Insurance  Proceeds in respect of any
Non-Designated  Mortgage  Loan.  All Mortgage  Files and funds  collected or held by, or under the control
of, a Servicer in respect of any Non-Designated  Mortgage Loans,  whether from the collection of principal
and interest  payments or from  Liquidation  Proceeds,  including but not limited to, any funds on deposit
in a  Collection  Account,  shall be held by the  related  Servicer  for and on behalf of the  Trust,  the
Trustee or the Trust  Administrator and shall be and remain the sole and exclusive  property of the Trust,
subject to the  applicable  provisions  of this  Agreement.  Each  Servicer  also agrees that it shall not
create,  incur or subject any  Mortgage  File or any funds that are  deposited  in the related  Collection
Account,  Certificate  Account or any  related  Escrow  Account,  or any funds that  otherwise  are or may
become due or  payable  to the  Trust,  the  Trustee  or the Trust  Administrator  for the  benefit of the
Certificateholders,  to any claim, lien,  security interest,  judgment,  levy, writ of attachment or other
encumbrance,  or assert by legal  action or  otherwise  any claim or right of setoff  against any Mortgage
File or any funds collected on, or in connection with, a Non-Designated  Mortgage Loan,  except,  however,
that such  Servicer  shall be entitled to set off against and deduct from any such funds any amounts  that
are properly due and payable to such Servicer under this Agreement.

SECTION 3.14.     Servicing Fee; Indemnification of Master Servicer.

(a)      As  compensation  for its services  hereunder,  each Servicer  shall be entitled to withdraw from
the  applicable  Collection  Account or to retain from  interest  payments  on the related  Non-Designated
Mortgage  Loans,  the amount of its Servicing Fee, for each Mortgage Loan serviced by it, less any amounts
in  respect   of  its   Servicing   Fee,   as   applicable,   payable  by  such   Servicer   pursuant   to
Section 3.05(c)(vi).  The  Servicing  Fee for each  Servicer is limited to, and payable  solely from,  the
interest  portion of such  Scheduled  Payments  collected  by such  Servicer or as  otherwise  provided in
Section 3.08(a).  In connection  with the servicing of any Special  Serviced  Mortgage  Loan,  the Special
Servicer shall receive the Servicing Fee for such Special  Serviced  Mortgage Loan as its compensation and
Ancillary Income with respect to Special Serviced Mortgage Loans.

(b)      With respect to each  Non-Designated  Mortgage Loan,  additional  servicing  compensation  in the
form of  Ancillary  Income and Excess  Proceeds  shall be  retained by the  related  Servicer,  additional
servicing  compensation  in the form of Payoff  Interest  not  required  to make  payments  in  respect of
Compensating  Interest  Payments  shall be retained  by SPS.  Each  Servicer  shall be required to pay all
expenses incurred by it in connection with its servicing  activities  hereunder  (including the payment of
any  expenses   incurred  in  connection  with  any  Subservicing   Agreement  entered  into  pursuant  to
Section 3.02 and the payment of any premiums for insurance  required  pursuant to Section 3.16)  and shall
not be entitled to reimbursement thereof except as specifically provided for in this Agreement.

(c)      The Master Servicer shall be compensated by the Trust  Administrator  as separately  agreed.  The
Master Servicer and any director,  officer,  employee or agent of the Master Servicer shall be indemnified
by DLJMC (or if DLJMC shall fail to do so, by the Trust) and held  harmless  against  any loss,  liability
or expense  (including  reasonable  attorney's fees and expenses) incurred in connection with any claim or
legal action relating to (a) this  Agreement,  (b) the  Certificates or (c) the  performance of any of the
Master  Servicer's  duties  hereunder,  other than any loss,  liability  or expense  incurred by reason of
willful  misfeasance,  bad faith or negligence in the performance of any of the Master  Servicer's  duties
hereunder  or  incurred  by reason of any  action of the Master  Servicer  taken at the  direction  of the
Certificateholders;  provided,  however,  that the sum of (x) such  indemnity  amounts payable by DLJMC or
the Trust to the Master Servicer  pursuant to this  Section 3.14(c),  (y) the indemnity amounts payable by
DLJMC or the Trust to the Trust  Administrator  pursuant to Section 10.05  and (z) the  indemnity  amounts
payable  by DLJMC or the  Trust to Wells  Fargo,  as  Custodian,  pursuant  to the Wells  Fargo  Custodial
Agreement,  shall not exceed $200,000 per year; provided,  further,  that any amounts not payable by DLJMC
or the Trust to the Master  Servicer due to the  preceding  proviso shall be payable by DLJMC (or if DLJMC
fails to do so, by the  Trust)  in any  succeeding  year,  subject  to the  aggregate  $200,000  per annum
limitation  imposed by the  preceding  proviso.  Such  indemnity  shall  survive the  termination  of this
Agreement or the resignation or removal of the Master Servicer hereunder.

SECTION 3.15.     Access to Certain Documentation.

                  The Master  Servicer and each  Servicer  shall provide to the Depositor and the Trustee,
at the request of the OTS and the FDIC and to comparable  regulatory  authorities  supervising  Holders of
Subordinate  Certificates  and the  examiners and  supervisory  agents of the OTS, the FDIC and such other
authorities,  access to the documentation  regarding the related Non-Designated Mortgage Loans required by
applicable  regulations of the OTS and the FDIC. Such access shall be afforded  without  charge,  but only
upon reasonable and prior written  request and during normal  business hours at the offices  designated by
the Master  Servicer or such  Servicer.  Nothing in this  Section 3.15  shall limit the  obligation of the
Master  Servicer or any Servicer to observe any  applicable  law  prohibiting  disclosure  of  information
regarding the  Mortgagors  and the failure of the Master  Servicer or such  Servicer to provide  access as
provided  in this  Section 3.15  as a result  of such  obligation  shall not  constitute  a breach of this
Section 3.15.  Nothing  in this  Section 3.15  shall  require  the  Master  Servicer  or any  Servicer  to
collect,  create,  collate or otherwise  generate any  information  that it does not generate in its usual
course of business.

SECTION 3.16.     Maintenance of Fidelity Bond and Errors and Omissions Insurance.

                  Each Servicer shall maintain with responsible  companies,  at its own expense, a blanket
Fidelity  Bond and an Errors  and  Omissions  Insurance  Policy,  with  broad  coverage  on all  officers,
employees  or other  persons  acting in any  capacity  requiring  such  persons  to handle  funds,  money,
documents or papers  relating to the related  Mortgage  Loans  ("Servicer  Employees").  Any such Fidelity
Bond and Errors and  Omissions  Insurance  Policy  shall be in the form of the Mortgage  Banker's  Blanket
Bond and shall  protect  and insure  the  related  Servicer  against  losses,  including  forgery,  theft,
embezzlement,  fraud,  errors and omissions and negligent acts of such Servicer  Employees.  Such Fidelity
Bond and Errors and  Omissions  Insurance  Policy  also shall  protect and insure  each  Servicer  against
losses in connection with the release or  satisfaction of a related  Mortgage Loan without having obtained
payment in full of the indebtedness  secured  thereby.  No provision of this  Section 3.16  requiring such
Fidelity  Bond and Errors and  Omissions  Insurance  Policy shall  diminish or relieve a Servicer from its
duties and  obligations  as set forth in this  Agreement.  The  minimum  coverage  under any such bond and
insurance  policy  shall be at least  equal to the  corresponding  amounts  required  by FNMA,  unless the
related Servicer has obtained a waiver of such requirement.  Upon the request of the Trust  Administrator,
the related  Servicer  shall cause to be delivered to the Trust  Administrator  a certificate of insurance
of the insurer and the surety  including a statement  from the surety and the insurer  that such  fidelity
bond and insurance  policy shall in no event be terminated or materially  modified  without 30 days' prior
written notice to the Trust Administrator.

                  The Master Servicer shall maintain  insurance in such amounts  generally  acceptable for
entities serving as master servicer.

SECTION 3.17.     Special Serviced Mortgage Loans.

                  If directed by the Special  Servicer  and solely at the  Special  Servicer's  option,  a
Servicer (a  "Transferring  Servicer")  shall  transfer the servicing of any Mortgage Loan serviced by the
Transferring  Servicer which is 90 days or more delinquent  (determined as of the close of business of the
last day of the month preceding the related Data  Remittance  Date) to the Special  Servicer.  The Special
Servicer shall thereupon assume all of the rights and obligations of the Transferring  Servicer  hereunder
arising  thereafter and the  Transferring  Servicer shall have no further rights or obligations  hereunder
with respect to such Mortgage Loan (except that the Special  Servicer  shall not be (i) liable  for losses
of the  Transferring  Servicer  pursuant  to  Section 3.09  hereof  or for any  acts or  omissions  of the
Transferring  Servicer  hereunder  prior to the  servicing  transfer  date,  (ii) obligated  to effectuate
repurchases or substitutions  of Mortgage Loans hereunder  including,  but not limited to,  repurchases or
substitutions  of Mortgage Loans pursuant to  Section 2.02  or 2.03 hereof,  (iii) deemed to have made any
representations  and  warranties  of a  Transferring  Servicer  hereunder or (iv) be  subject to any other
agreement  not  executed  by the  Special  Servicer).  Upon  the  transfer  of the  servicing  of any such
Mortgage Loan to the Special  Servicer,  the Special  Servicer shall be entitled to the related  Servicing
Fee and other  compensation  accruing  after the  servicing  transfer  date with respect to such  Mortgage
Loans pursuant to Section 3.14.

                  In  connection  with the transfer of the  servicing of any Mortgage  Loan to the Special
Servicer,  the Transferring  Servicer,  at the Special  Servicer's  expense,  shall deliver to the Special
Servicer  all  documents  and  records  relating  to such  Mortgage  Loans and an  accounting  of  amounts
collected or held by it and otherwise  use its best efforts to effect the orderly and  efficient  transfer
of the servicing to the Special  Servicer.  On the servicing  transfer  date,  the Special  Servicer shall
reimburse  the  Transferring  Servicer for all  unreimbursed  Advances,  Servicing  Advances and Servicing
Fees, as  applicable,  relating to the Mortgage  Loans for which the servicing is being  transferred.  The
Special  Servicer shall be entitled to be reimbursed  pursuant to  Section 3.08  or otherwise  pursuant to
this Agreement for all such Advances,  Servicing  Advances and Servicing Fees, as applicable,  paid by the
Transferring  Servicer pursuant to this Section 3.17.  In addition,  the Special Servicer shall notify the
Master  Servicer of such transfer and the  effective  date of such  transfer,  and amend the Mortgage Loan
Schedule to reflect that such Mortgage Loans are Special Serviced Mortgage Loans.

SECTION 3.18.     Indemnification of Servicers and Master Servicer.

                  Each  Servicer  agrees to  indemnify  and hold the  Master  Servicer  harmless  from and
against any and all losses,  claims,  expenses,  costs or liabilities  (including attorneys fees and court
costs)  incurred by the Master  Servicer as a result of or in connection with the failure by such Servicer
to perform the  obligations  or  responsibilities  imposed upon or undertaken by such Servicer  under this
Agreement.

                  The  Master  Servicer  agrees to  indemnify  and hold each  Servicer  harmless  from and
against any and all losses,  claims,  expenses,  costs or liabilities  (including attorneys fees and court
costs)  incurred by such Servicer as a result of or in connection  with the failure by the Master Servicer
to perform the  obligations or  responsibilities  imposed upon or undertaken by the Master  Servicer under
this Agreement.

SECTION 3.19.     Notification of Adjustments.

                  With  respect to each  Mortgage  Loan,  the related  Servicer  shall adjust the Mortgage
Rate on the  related  Adjustment  Date in  compliance  with the  requirements  of  applicable  law and the
related  Mortgage  and  Mortgage  Note.  The  related  Servicer  shall  execute  and  deliver  any and all
necessary  notices  required under  applicable law and the terms of the related Mortgage Note and Mortgage
regarding the Mortgage  Rate  adjustments.  Upon the  discovery by the related  Servicer or the receipt of
notice  from the  Trust  Administrator  that  such  Servicer  has  failed  to  adjust a  Mortgage  Rate in
accordance  with the terms of the related  Mortgage Note, such Servicer shall  immediately  deposit in the
Certificate  Account  from its own funds the  amount of any  interest  loss or  deferral  caused the Trust
Administrator thereby.

SECTION 3.20.     Designated Mortgage Loans.

(a)      For and on behalf of the  Certificateholders,  the Master  Servicer shall oversee and enforce the
obligation of each  Designated  Servicer to service and administer the related  Designated  Mortgage Loans
in accordance with the terms of the related Designated  Servicing  Agreement and shall have full power and
authority to do any and all things  which it may deem  necessary  or  desirable  in  connection  with such
master servicing and administration.  In performing its obligations  hereunder,  the Master Servicer shall
act in a manner  consistent  with this  Agreement and with  customary  and usual  standards of practice of
prudent mortgage loan master  servicers.  Furthermore,  the Master Servicer shall oversee and consult with
each Designated  Servicer as necessary from  time-to-time to carry out the Master  Servicer's  obligations
hereunder,  and shall  receive,  review and evaluate all reports,  information  and other data provided to
the Master Servicer by each Designated Servicer.

                  The  Master  Servicer  shall  terminate  the rights and  obligations  of any  Designated
Servicer under the related Designated  Servicing  Agreement,  upon the failure of such Designated Servicer
to perform any of its obligations under such Designated Servicing  Agreement,  which failure results in an
event of default as  provided  in  Section 14  of the  Countrywide  Underlying  Servicing  Agreement  with
respect to  Countrywide,  as provided in  Section 8.01 of the Hemisphere  Underlying  Servicing  Agreement
with respect to Hemisphere,  as provided in  Section 12.07  and Section W of Exhibit M to the CitiMortgage
Underlying  Servicing  Agreement with respect to CitiMortgage,  and as provided in Subsection 12.01 of the
BofA  Underlying  Servicing  Agreement  with  respect  to BofA.  In the  event a  Designated  Servicer  is
terminated  pursuant to the preceding  sentence,  the Master  Servicer  shall notify the Depositor and the
Trust  Administrator and shall either  (a) select and engage a successor  servicer of the related Mortgage
Loans or (b) act as successor  servicer of the related  Mortgage  Loans.  In either case,  the  Designated
Mortgage Loans related to such Designated  Servicing  Agreement shall be serviced by the successor to such
Designated Servicer pursuant to the servicing  provisions of this Agreement,  and such Designated Mortgage
Loans shall be deemed as "Non-Designated  Mortgage Loans" under this Agreement;  provided,  however, it is
understood  and  acknowledged  by the  parties  hereto that there will be a period of  transition  (not to
exceed  90 days)  before  the  actual  servicing  functions  can be fully  transferred  to such  successor
Designated Servicer.  Such enforcement,  including,  without limitation,  the legal prosecution of claims,
termination of Designated  Servicing  Agreements 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,  in its good
faith  business  judgment,  would  require  were it the owner of the related  Mortgage  Loans.  The Master
Servicer  shall pay the costs of such  enforcement at its own expense,  provided that the Master  Servicer
shall not be  required  to  prosecute  or defend any legal  action  except to the  extent  that the Master
Servicer shall have received reasonable indemnity for its costs and expenses in pursuing such action.

                  To the  extent  that the  costs and  expenses  of the  Master  Servicer  related  to any
termination of a Designated  Servicer,  appointment of a successor Designated Servicer or the transfer and
assumption  of  servicing  by the Master  Servicer  with  respect to any  Designated  Servicing  Agreement
(including,  without  limitation,  (i) all  legal  costs  and  expenses  and all due  diligence  costs and
expenses  associated with an evaluation of the potential  termination of a Designated Servicer as a result
of an event of default by such  Designated  Servicer and (ii) all costs and expenses  associated  with the
complete  transfer of servicing,  including all servicing files and all servicing data and the completion,
correction  or  manipulation  of such  servicing  data as may be  required  by the  successor  servicer to
correct  any  errors or  insufficiencies  in the  servicing  data or  otherwise  to enable  the  successor
servicer to service the Mortgage  Loans in accordance  with this  Agreement)  are not fully  reimbursed by
the terminated  Designated Servicer,  the Master Servicer shall be entitled to reimbursement of such costs
and expenses from the Trust.

(b)      Each month,  if a Designated  Servicer fails to make a required  Advance by the date such Advance
is required to be made under the related  Designated  Servicing  Agreement,  the Master  Servicer shall on
the Cash Remittance Date deposit in the amount of any required Advance in the Certificate Account.

(c)      Each month,  the Master Servicer shall make  Compensating  Interest  Payments with respect to the
Designated Mortgage Loans to the extent provided in Section 3.03.

SECTION 3.21.     Assigned Prepayment Premiums.

                  Notwithstanding  anything  in  this  Agreement  to  the  contrary,  in  the  event  of a
Principal  Prepayment,  the applicable  Servicer may not waive any Assigned  Prepayment Premium or portion
thereof  required by the terms of the related  Mortgage Note unless  (i) the  related  Mortgage Loan is in
default or foreseeable  default and such waiver (a) is standard and customary in servicing  mortgage loans
similar to the  Mortgage  Loans and  (b) would,  in the  reasonable  judgment of such  Servicer,  maximize
recovery of total  proceeds  taking into  account the value of such  Assigned  Prepayment  Premium and the
related  Mortgage Loan,  (ii) (A) the  enforceability  thereof is limited (1) by  bankruptcy,  insolvency,
moratorium,  receivership,  or other  similar law relating to  creditors'  rights  generally or (2) due to
acceleration in connection with a foreclosure or other involuntary  payment,  or (B) the enforceability is
otherwise  limited  or  prohibited  by  applicable  law,  (iii) the  enforceability  would  be  considered
"predatory"  pursuant to written  guidelines  issued by any applicable  federal,  state or local authority
having  jurisdiction over such matters,  (iv) such Servicer is unable to locate  documentation  sufficient
to allow it to  confirm  the  existence  and  amount  of such  Assigned  Prepayment  Premium  after  using
commercially  reasonable efforts to locate such  documentation,  which efforts shall include,  but are not
limited to, seeking such  documentation  from the Depositor,  the Seller,  the related  Custodian and from
its own records or files or (v) the related  Mortgaged  Property  has been  damaged  such that the current
value of the  Mortgaged  Property has been  reduced by at least half as a result of a natural  disaster or
other  insured or  uninsured  peril,  and the  borrower  has  elected to pay the loan in full  rather than
rebuild  the  Mortgaged  Property.  For the  avoidance  of doubt,  the  applicable  Servicer  may waive an
Assigned  Prepayment  Premium in  connection  with a short sale or short  payoff on a  defaulted  Mortgage
Loan. If an applicable  Servicer has waived all or a portion of an Assigned  Prepayment  Premium  relating
to a  Principal  Prepayment,  other than as  provided  above,  such  Servicer  shall  deliver to the Trust
Administrator  no later than the next succeeding  Cash  Remittance  Date, for deposit into the Certificate
Account the amount of such Assigned  Prepayment  Premium (or such portion  thereof as had been waived) for
distribution  in accordance  with the terms of this  Agreement and if such Servicer  fails to deliver such
amount, any of the Trust  Administrator,  the Master Servicer,  the Trustee or the Seller may enforce such
obligation.  If such  Servicer  has waived  all or a portion of an  Assigned  Prepayment  Premium  for any
reason,  it shall include such  information,  including the reason for such waiver, in any monthly reports
it provides,  and such  Servicer if other than Wells  Fargo,  shall  notify the Trust  Administrator,  the
Seller,  the Master  Servicer and the Trustee of such waiver,  and if such Servicer is Wells Fargo,  Wells
Fargo shall notify the Trust  Administrator and the Trust  Administrator  shall forward any such notice to
the Seller,  the Master Servicer and the Trustee.  Notwithstanding  any provision in this Agreement to the
contrary,  in the event the Assigned  Prepayment  Premium payable under the terms of the related  Mortgage
Note is less  than  the  amount  of the  Assigned  Prepayment  Premium  set  forth  in the  Mortgage  Loan
Schedule or  other  information  provided to the  applicable  Servicer,  such Servicer  shall not have any
liability  or  obligation  with  respect  to such  difference.  The  Master  Servicer  shall  not have any
responsibility  for verifying the accuracy of the amount of Assigned  Prepayment  Premiums remitted by the
Servicers.

                  Notwithstanding  anything in this  Agreement to the contrary,  the Trustee and the Trust
Administrator  shall have no  obligation  to collect  Prepayment  Premiums from any Servicer or Designated
Servicer  other than Wells Fargo,  in its capacity as a Servicer (or any of its  successors  and assigns),
GreenPoint (or any of its successors and assigns) or SPS (or any of its successors and assigns).

                                                ARTICLE IV

                              PAYMENTS AND STATEMENTS TO CERTIFICATEHOLDERS

SECTION 4.01.     Priorities of Distribution.

                  (I)      (A)      On each  Distribution  Date,  with  respect to the  Group 1,  Group 2,
Group 3 and Class C-B Certificates,  the Trust Administrator shall determine the amounts to be distributed
to each Class of Certificates as follows:

(a)      with respect to the Group 1  Certificates,  from the Available  Distribution  Amount  relating to
         Loan Group 1:

(i)      first,  concurrently,  to the Group 1  Certificates and the Class C-M-1  Certificates,  an amount
         allocable  to  interest  equal to the  related  Interest  Distribution  Amount  for such
         Distribution  Date,  any shortfall  being  allocated pro rata between such Classes based
         on the Interest  Distribution  Amount that would have been distributed in the absence of
         such shortfall; and

(ii)     second,  on each  Distribution  Date,  from the  Available  Distribution  Amount for Loan Group 1
         remaining    after    giving    effect    to    the     distributions     pursuant    to
         Section 4.01(I)(A)(a)(i) above,  the Group 1 Senior Principal  Distribution  Amount,  as
         principal, sequentially, as follows:

(A)      first,  to the Class AR and Class AR-L  Certificates,  pro rata based on their  respective  Class
         Principal  Balances  immediately prior to such  Distribution  Date, until their
         respective Class Principal Balances have been reduced to zero; and

(B)      second,  the Group 1 Senior Principal  Distribution  Amount for that  Distribution Date remaining

Shortfalls  for Mortgage Loans in the related Loan Group for  such  Distribution  Date and  (ii) (A) after

interest on such Mortgage Loan with respect to such month, (B) after the Bankruptcy  Coverage  Termination
Date, with respect to each Group 1,  Group 2 or Group 3 Mortgage Loan, as applicable,  that became subject

at the related Net  Mortgage  Rate on the Stated  Principal  Balance of such  Mortgage  Loan as of the Due
Date in such month over the amount of  Liquidation  Proceeds  applied as  interest on such  Mortgage  Loan
with  respect to such month.  For purposes of  calculating  the  reduction  of the  Interest  Distribution
Amount for the  Class C-M-1  Certificates  with respect to Loan Group 1 or Loan  Group 3,  such  reduction
shall be based on the  amount  of  interest  accruing  at the Net WAC  Rate  for such  Loan  Group on  the
Class C-M-1  Group 1 Component Balance and Class C-M-1  Group 3 Component Balance,  respectively,  in each
case for such  Distribution  Date. For purposes of calculating the reduction of the Interest  Distribution
Amount for each  Class of  Class C-B  Certificates  with  respect to Loan  Group 1,  Loan  Group 2 or Loan

Subordinate Component Balance for that Distribution Date.

                  (C)      With respect to each Class of  Class C-B  Certificates,  if on any Distribution
Date the related  Subordination  Level of such Class is less than such  percentage as of the Closing Date,
no distribution of Principal  Prepayments shall be made to any Class or Classes of Class C-B  Certificates
junior to such Class (the  "Restricted Classes") and the amount otherwise  distributable to the Restricted
Classes in  respect of such  Principal  Prepayments  shall be  allocated  among the  remaining  Classes of
Class C-B Certificates, pro rata, based upon their respective Class Principal Balances.

                  (D)      The Trust  Administrator  shall  distribute the Mortgage Loan Purchase Price of
any  Optional  Termination  of Loan  Group 1,  Loan Group 2 and Loan Group 3 in excess of the Par Value to
the holder of the Class AR-L Certificate.

         Certificates,  in decreasing  order of their  alphanumerical  Class designations  (beginning with
         the  Class C-B-6  Certificates),  until  the  respective  Class  Principal  Balance  of each such

         Certificate Group, as follows:

Balance  of  a  Class of  Certificates  pursuant  to  Section 4.02(b) shall  be  allocated  by  the  Trust

lowest relative payment  priority  (beginning with the Class 4-B-1  Certificates),  in each case until the
respective  Class  Principal  Balance  thereof  has been  reduced to zero.  Any  Applied  Loss Amount with
respect to the Group 4 Certificates  allocated to a Class of the Class 4-B-1  Certificates,  the Class 4-M

                  The Master  Servicer,  with respect to the Mortgage  Loans and each  Distribution  Date,
shall provide to the Trust  Administrator  the information set forth in Exhibits H-1,  H-2 and H-3 in such
form as the Trust  Administrator  shall  reasonably  request no later than twelve noon on the related Data
Remittance  Date or on the related  Additional Data  Remittance  Date, as applicable,  to enable the Trust
Administrator  to calculate  the amounts to be  distributed  to each Class of  Certificates  and otherwise
perform its distribution, accounting and reporting requirements hereunder.

SECTION 4.07.     Cross-Collateralization; Adjustments to Available Funds.

(a)      With respect to Loan Group 1, Loan Group 2 and Loan Group 3, on each  Distribution  Date prior to
the Class C-B  Credit Support  Depletion  Date, but after the date on which the aggregate  Class Principal
Balance of the Group 1,  Group 2 or Group 3  Certificates has been reduced to zero (and in the case of the
Group 1 or Group 3 Certificates,  the Class Principal  Balance of the  Class C-M-1  Certificates  has also
been reduced to zero), the Trust  Administrator  shall  distribute the principal  portion of the Available
Distribution  Amount on the Mortgage Loans relating to such Senior  Certificates  that will have been paid
in full, to the holders of the Senior  Certificates of the other Certificate  Group(s).  Such amount shall
be allocated among the other Certificate  Groups,  pro rata, based on aggregate Class Principal Balance of
the related Senior  Certificates  and paid to the Senior  Certificates in each such  Certificate  Group in
the same  priority as such  Certificates  would  receive  other  distributions  of  principal  pursuant to
Section 4.01(I)(A);  provided,  however,  that the Trust Administrator shall not make such distribution on
such  Distribution  Date if (a) the  Class C-B  Percentage for such  Distribution  Date is greater than or
equal to 200% of such  Class C-B  Percentage  as of the  Closing  Date  and  (b) the  average  outstanding
principal  balance of the Mortgage Loans in each Loan  Group delinquent  60 days or more over the last six
months, as a percentage of the related Subordinate Component Balance, is less than 50%.

(b)      With  respect to Loan Group 1, Loan  Group 2 and Loan  Group 3, if on any  Distribution  Date the
aggregate Class Principal Balance of the Group 1,  Group 2 or Group 3  Certificates  (plus, in the case of
the Group 1 or Group 3 Certificates,  the Class  Principal  Balance of the  Class C-M-1  Certificates)  is
greater than the Aggregate Loan Group Balance of the related Loan Group (each  Loan  Group related to such
Group of  Certificates,  an  "Undercollateralized  Group"),  then the Trust Administrator shall reduce the
Available  Distribution  Amount of the other  Loan  Group(s)  that is not  undercollateralized  (each,  an
"Overcollateralized Group"), as follows:

(1)      to add to the Available Distribution Amount of the  Undercollateralized  Group(s) an amount equal
         to  the  lesser  of  (a) one   month's   interest  on  the  Principal   Transfer  Amount  of  the
         Undercollateralized  Group(s) at the Net WAC Rate applicable to the Undercollateralized  Group(s)
         and (b) the  Available  Distribution  Amount of the  Overcollateralized  Groups  remaining  after
         making interest  distributions to the Senior Certificates of the  Overcollateralized  Group(s) on
         such Distribution Date pursuant to Section 4.01; and

(2)      to the Senior  Certificates  of each  Undercollateralized  Group,  to the extent of the principal
         portion of the Available Distribution Amount of the  Overcollateralized  Group(s) remaining after
         making   interest   and   principal   distributions   to   the   Senior   Certificates   of   the
         Overcollateralized  Group(s) on such Distribution Date pursuant to Section 4.01,  until the Class
         Principal  Balance of the Senior  Certificates  of such  Undercollateralized  Group(s) equals the
         Aggregate  Loan  Group  Balance  of the  related  Loan  Group(s).  Payments  shall be made to the
         Senior  Certificates in each Group in the same priority as such Certificates  would receive other
         distributions of principal pursuant to Section 4.01(I)(A).

(c)      If more than one  Overcollateralized  Group exists on any  Distribution  Date,  reductions in the
Available  Distribution  Amount of such  Groups  to make the  payments  required  to be made  pursuant  to
Section 4.07(b) on  such  Distribution  Date  shall be made pro rata,  based on the  Overcollateralization
Amount  of each  Overcollateralized  Group.  If more  than  one  Undercollateralized  Group exists  on any
Distribution  Date,  payments  made  to  such  Groups  from  the  Available  Distribution  Amount  of  the
Overcollateralized  Group shall be made pro rata,  based on the amount of payments  required to be made to
the Undercollateralized Group(s).

SECTION 4.08.     Group 4 Interest Rate Cap Accounts.

(a)      On the Closing  Date,  the Trust  Administrator  shall  establish  and  maintain in its name,  on
behalf of the  Trustee  and in trust for the  benefit of the  Holders of the  Class 4-X  Certificates,  an
account    relating    to   the    Class 4-A-1/4-A-3/4-A-4    Interest    Rate    Cap    Agreement    (the
"Class 4-A-1/4-A-3/4-A-4  Interest Rate Cap Account"),  an account  relating to the  Class 4-A-2  Interest
Rate Cap  Agreement  (the  "Class 4-A-2  Interest  Rate  Cap  Account")  and an  account  relating  to the
Class 4-M/4-B  Interest Rate Cap Agreement (the "Class 4-M/4-B  Interest Rate Cap Account").  Each Group 4
Interest  Rate Cap  Account  shall be an  Eligible  Account,  and funds on deposit  therein  shall be held
separate  and  apart  from,  and  shall not be  commingled  with,  any  other  moneys,  including  without
limitation, other moneys held by the Trust Administrator pursuant to this Agreement.

(b)      On each  Distribution  Date on and after the Distribution Date in August 2006 and on and prior to
the Distribution Date in December 2010,  the Trust  Administrator shall deposit any amounts paid under the
Class 4-A-1/4-A-3/4-A-4  Interest Rate Cap Agreement  into the  Class 4-A-1/4-A-3/4-A-4  Interest Rate Cap
Account.  On any Distribution  Date, amounts on deposit in the  Class 4-A-1/4-A-3/4-A-4  Interest Rate Cap
Account  shall be  distributed,  pro rata  based on  amounts  due,  to the  Class 4-A-1-1,  Class 4-A-1-2,
Class 4-A-3-1,  Class 4-A-3-2,  Class 4-A-3-3  and  Class 4-A-4  Certificates,  in an amount  equal to any
unpaid Basis Risk  Shortfall  for such class.  Amounts in respect of Basis Risk  Shortfalls  paid pursuant
to the  preceding  sentence  shall be made prior to giving  effect to any amounts  available to be paid in
respect  of such Basis Risk  Shortfalls  pursuant  to  Section 4.01(II)(d)(xiii)(a) on  such  Distribution
Date.  On any  Distribution  Date,  after  distributions  in  respect  of  Basis  Risk  Shortfalls  on the
Class 4-A-1-1,  Class 4-A-1-2,  Class 4-A-3-1,  Class 4-A-3-2,  Class 4-A-3-3 and Class 4-A-4 Certificates
pursuant to the first  sentence of this clause (b), the pro rata share of amounts  remaining on deposit in
the  Class 4-A-1/4-A-3/4-A-4  Interest Rate Cap Account, weighted based on the amount remaining on deposit
in the  Class 4-A-1/4-A-3/4-A-4  Interest  Rate  Cap  Account  as a  percentage  of the  aggregate  amount
remaining in the  Class 4-A-1/4-A-3/4-A-4  Interest Rate Cap Account,  the  Class 4-A-2  Interest Rate Cap
Account and the  Class 4-M/4-B  Interest Rate Cap Account,  in each case after making  payments in respect
of Basis Risk Shortfalls on the related  Certificates  and with respect to the  Class 4-A-2  Interest Rate
Cap Account,  payments to the Supplemental  Interest Trust,  shall be distributed  first, to the Principal
Remittance  Amount,  up to the amount of Realized  Losses on the Mortgage  Loans in Loan Group 4  incurred
during  the  related  Collection  Period  and  second,  sequentially,  to  the  Class 4-A-4,  Class 4-M-1,
Class 4-M-2,  Class 4-M-3,  Class 4-M-4,  Class 4-M-5,  Class 4-M-6, Class 4-M-7, Class 4-M-8, Class 4-M-9
and Class 4-B-1  Certificates,  in that order, any applicable  Deferred Amounts,  with interest therein at
the applicable  Pass-Through  Rate,  prior to giving effect to amounts  available to be paid in respect of
Deferred Amounts as described in Section 4.01(II)(d)(ii)-(xii) on such Distribution Date.

                  Amounts paid under the  Class 4-A-1/4-A-3/4-A-4  Interest Rate Cap Agreement not used on
any Distribution Date as described above shall remain on deposit in the  Class 4-A-1/4-A-3/4-A-4  Interest
Rate Cap Account and may be  available  on future  Distribution  Dates to make the  payments  described in
this  Section 4.08(c).  However,  at no time shall the  amount on  deposit in the  Class 4-A-1/4-A-3/4-A-4
Interest    Rate   Cap    Account    exceed    the    Class 4-A-1/4-A-3/4-A-4    Deposit    Amount.    The
"Class 4-A-1/4-A-3/4-A-4  Deposit  Amount"  shall be calculated on each  Distribution  Date,  after giving
effect to  withdrawals  from the  Class 4-A-1/4-A-3/4-A-4  Interest Rate Cap Account on such  Distribution
Date  and  distributions  and  allocation  of  Realized  Losses  on  the  Group 4   Certificates  on  such
Distribution  Date,  and will  equal  the  product  of (x) a  fraction,  expressed  as a  percentage,  the
numerator  of  which  is  equal  to  the  aggregate   Class  Principal   Balance  of  the   Class 4-A-1-1,
Class 4-A-1-2,  Class 4-A-3-1,  Class 4-A-3-2,  Class 4-A-3-3  and Class 4-A-4  Certificates  after giving
effect  to  distributions  and  allocations  of  Realized  Losses  on  such  Distribution  Date,  and  the
denominator  of which is equal to the  aggregate  Class  Principal  Balance  of the  Group 4  Certificates
(other than the Class 4-X  Certificates)  after giving effect to distributions and allocations of Realized
Losses  on such  Distribution  Date and (2) the  excess,  if any,  of the  Targeted  Overcollateralization
Amount for such Distribution  Date over the  Overcollateralization  Amount for such Distribution  Date. On
each Distribution Date, the Trust  Administrator  shall distribute amounts in the  Class 4-A-1/4-A-3/4-A-4
Interest  Rate Cap  Account  in  excess of the  Class 4-A-1/4-A-3/4-A-4  Deposit  Amount to the  Class 4-X
Certificateholders.  On the  Distribution  Date  immediately  after  the  Distribution  Date on which  the
aggregate Class  Principal  Balance of the  Class 4-A-1-1,  Class 4-A-1-2,  Class 4-A-3-1,  Class 4-A-3-2,
Class 4-A-3-3   and   Class 4-A-4   Certificates   equals   zero,   any   amounts   on   deposit   in  the
Class 4-A-1/4-A-3/4-A-4  Interest  Rate Cap  Account  not  payable on the  Group 4  Certificates  shall be
distributed to the Class 4-X Certificateholders.

(c)      On each  Distribution  Date on and after the Distribution Date in August 2006 and on and prior to
the Distribution Date in December 2010,  the Trust  Administrator shall deposit any amounts paid under the
Class 4-A-2  Interest  Rate  Cap  Agreement  into  the  Class 4-A-2  Interest  Rate  Cap  Account.  On any
Distribution  Date or, in the case of payments to the  Supplemental  Interest  Trust,  on the related Swap
Payment  Date,  amounts on deposit in the  Class 4-A-2  Interest  Rate Cap  Account  shall be  distributed
first, to the  Supplemental  Interest Trust for payment to the Swap  Counterparty,  an amount equal to any
Swap Fee  Reimbursement  Amount for such Swap Payment Date or remaining unpaid from any prior Swap Payment
Date and second,  pro rata based on amounts due (1) to the Supplemental  Interest Trust for payment to the
Swap  Counterparty,  the Swap  Counterparty  Reimbursement  Amount for the related  Swap  Payment  Date or
remaining  unpaid  from any prior  Swap  Payment  Date and (2) on  any  Distribution  Date on which a Swap
Suspension Event has occurred and is continuing, to the Class 4-A-2  Certificates,  an amount equal to any
unpaid Basis Risk  Shortfall  for such class.  Amounts in respect of Basis Risk  Shortfalls  paid pursuant
to the  preceding  sentence  shall be made prior to giving  effect to any amounts  available to be paid in
respect of such Basis Risk Shortfalls  pursuant to  Section 4.01(II)(d)(xiii)(b)(ii) on  such Distribution
Date. On any  Distribution  Date or, in the case of payments to the  Supplemental  Interest  Trust, on the
related Swap Payment  Date,  after  distributions  to the  Supplemental  Interest  Trust and in respect of
Basis Risk Shortfalls on the Class 4-A-2  Certificates  pursuant to the first sentence of this clause (c),
the pro rata  share,  or amounts  remaining  on  deposit in the  Class 4-A-2  Interest  Rate Cap  Account,
weighted  based on the amount  remaining  on deposit in the  Class 4-A-2  Interest  Rate Cap  Account as a
percentage of the aggregate  amount  remaining in the  Class 4-A-1/4-A-3/4-A-4  Interest Rate Cap Account,
the Class 4-A-2  Interest Rate Cap Account and the Class 4-M/4-B  Interest Rate Cap Account,  in each case
after making  payments in respect of Basis Risk  Shortfalls on the related  Certificates  and with respect
to the  Class 4-A-2  Interest Rate Cap Account,  payments to the  Supplemental  Interest  Trust,  shall be
distributed  first,  to the  Principal  Remittance  Amount,  up to the  amount of  Realized  Losses on the
Mortgage Loans in Loan Group 4  incurred during the related  Collection  Period and second,  sequentially,
to  the  Class 4-A-4,   Class 4-M-1,  Class 4-M-2,  Class 4-M-3,  Class 4-M-4,  Class 4-M-5,  Class 4-M-6,
Class 4-M-7,  Class 4-M-8,  Class 4-M-9  and  Class 4-B-1  Certificates,  in that  order,  any  applicable
Deferred  Amounts,  with interest therein at the applicable  Pass-Through  Rate, prior to giving effect to
amounts    available    to   be   paid   in   respect   of    Deferred    Amounts    as    described    in
Section 4.01(II)(d)(ii)-(xii) on such Distribution Date.

                  Amounts  paid  under  the  Class 4-A-2  Interest  Rate  Cap  Agreement  not  used on any
Distribution  Date as  described  above  shall  remain on deposit  in the  Class 4-A-2  Interest  Rate Cap
Account  and may be  available  on  future  Distribution  Dates to make  the  payments  described  in this
Section 4.08(d).  However,  at no time shall the amount on deposit in the  Class 4-A-2  Interest  Rate Cap
Account exceed the Class 4-A-2  Deposit Amount.  The  "Class 4-A-2  Deposit Amount" shall be calculated on
each  Distribution  Date,  after giving  effect to  withdrawals  from the  Class 4-A-2  Interest  Rate Cap
Account on such  Distribution  Date and  distributions  and  allocation of Realized  Losses on the Group 4
Certificates  on such  Distribution  Date,  and will equal the product of (x) a fraction,  expressed  as a
percentage,  the  numerator  of  which  is  equal  to the  Class  Principal  Balance  of  the  Class 4-A-2
Certificates   after  giving  effect  to  distributions   and  allocations  of  Realized  Losses  on  such
Distribution  Date, and the denominator of which is equal to the aggregate Class Principal  Balance of the
Group 4  Certificates  (other than the Class 4-X  Certificates)  after giving effect to distributions  and
allocations  of Realized  Losses on such  Distribution  Date and (2) the excess,  if any, of the  Targeted
Overcollateralization  Amount for such  Distribution Date over the  Overcollateralization  Amount for such
Distribution  Date. On each Distribution  Date, the Trust  Administrator  shall distribute  amounts in the
Class 4-A-2  Interest  Rate Cap  Account  in excess of the  Class 4-A-2  Deposit  Amount to the  Class 4-X
Certificateholders.  On the  Distribution  Date  immediately  after  the  Distribution  Date on which  the
aggregate Class Principal Balance of the Class 4-A-2  Certificates  equals zero, any amounts on deposit in
the  Class 4-A-2  Interest Rate Cap Account not payable on the Group 4  Certificates  shall be distributed
to the Class 4-X Certificateholders.

(d)      On each  Distribution  Date on and after the Distribution Date in August 2006 and on and prior to
the Distribution Date in December 2010,  the Trust  Administrator shall deposit any amounts paid under the
Class 4-M/4-B  Interest  Rate Cap  Agreement  into the  Class 4-M/4-B  Interest  Rate Cap Account.  On any
Distribution  Date,  amounts  on  deposit  in  the  Class 4-M/4-B  Interest  Rate  Cap  Account  shall  be
distributed,  pro rata based on amounts due, to each Class of Class 4-M and Class 4-B-1  Certificates,  in
an amount  equal to any  unpaid  Basis Risk  Shortfall  for such  class.  Amounts in respect of Basis Risk
Shortfalls  paid  pursuant to the preceding  sentence  shall be made prior to giving effect to any amounts
available    to   be   paid   in    respect    of    such    Basis    Risk    Shortfalls    pursuant    to
Section 4.01(II)(d)(xiv)-(xxiii) on   such   Distribution   Date.   On  any   Distribution   Date,   after
distributions   in  respect  of  Basis  Risk  Shortfalls  on  each  Class  of  Class 4-M  and  Class 4-B-1
Certificates  pursuant to the first  sentence of this clause (d), the pro rata share of amounts  remaining
on deposit in the  Class 4-M/4-B  Interest  Rate Cap Account,  weighted  based on the amount  remaining on
deposit in the  Class 4-M/4-B  Interest Rate Cap Account as a percentage of the aggregate amount remaining
in the  Class 4-A-1/4-A-3/4-A-4  Interest Rate Cap Account,  the Class 4-A-2 Interest Rate Cap Account and
the Class 4-M/4-B  Interest Rate Cap Account,  in each case after making payments in respect of Basis Risk
Shortfalls  on the related  Certificates  and with respect to the  Class 4-A-2  Interest Rate Cap Account,
payments to the  Supplemental  Interest Trust,  shall be distributed  first,  to the Principal  Remittance
Amount,  up to the amount of Realized  Losses on the Mortgage  Loans in Loan Group 4  incurred  during the
related  Collection  Period  and  second,  sequentially,  to the  Class 4-A-4,  Class 4-M-1,  Class 4-M-2,
Class 4-M-3,  Class 4-M-4, Class 4-M-5, Class 4-M-6, Class 4-M-7, Class 4-M-8, Class 4-M-9 and Class 4-B-1
Certificates,  in that order,  any applicable  Deferred  Amounts,  with interest therein at the applicable
Pass-Through  Rate, prior to giving effect to amounts  available to be paid in respect of Deferred Amounts
as described in Section 4.01(II)(d)(ii)-(xii) on such Distribution Date.

                  Amounts  paid  under  the  Class 4-M/4-B  Interest  Rate Cap  Agreement  not used on any
Distribution  Date as  described  above shall  remain on deposit in the  Class 4-M/4-B  Interest  Rate Cap
Account  and may be  available  on  future  Distribution  Dates to make  the  payments  described  in this
Section 4.08(c).  However,  at no time shall the amount on deposit in the Class 4-M/4-B  Interest Rate Cap
Account exceed the Class 4-M/4-B  Deposit Amount. The  "Class 4-M/4-B  Deposit Amount" shall be calculated
on each  Distribution  Date, after giving effect to withdrawals from the  Class 4-M/4-B  Interest Rate Cap
Account on such  Distribution  Date and  distributions  and  allocation of Realized  Losses on the Group 4
Certificates  on such  Distribution  Date,  and will equal the product of (x) a fraction,  expressed  as a
percentage,  the numerator of which is equal to the  aggregate  Class  Principal  Balance of the Class 4-M
and Class 4-B-1  Certificates  after giving effect to distributions  and allocations of Realized Losses on
such  Distribution  Date, and the denominator of which is equal to the aggregate  Class Principal  Balance
of the Group 4  Certificates (other than the Class 4-X  Certificates) after giving effect to distributions
and allocations of Realized Losses on such  Distribution  Date and (2) the excess, if any, of the Targeted
Overcollateralization  Amount for such  Distribution Date over the  Overcollateralization  Amount for such
Distribution  Date. On each Distribution  Date, the Trust  Administrator  shall distribute  amounts in the
Class 4-M/4-B  Interest Rate Cap Account in excess of the  Class 4-M/4-B  Deposit  Amount to the Class 4-X
Certificateholders.  On the  Distribution  Date  immediately  after  the  Distribution  Date on which  the
aggregate Class Principal Balance of the Class 4-M and Class 4-B-1  Certificates  equals zero, any amounts
on deposit in the Class 4-M/4-B  Interest Rate Cap Account not payable on the Group 4  Certificates  shall
be distributed to the Class 4-X Certificateholders.

(e)      Funds in the Group 4  Interest Rate Cap Accounts may be invested in Eligible  Investments  by the
Trust  Administrator  at the  direction  of the  Depositor  maturing  on or prior  to the next  succeeding
Distribution  Date. The Trust  Administrator  shall account for each Group 4  Interest Rate Cap Account as
an outside  reserve  fund within the meaning of Treasury  regulation  1.860G-2(h) and  not an asset of any
REMIC  created  pursuant to this  Agreement.  The Trust  Administrator  shall treat  amounts paid from the
Group 4  Interest  Rate Cap  Accounts  as  payments  made from  outside  the  REMICs for all  Federal  tax
purposes.  Any net investment  earnings on such amounts shall be payable to the  Depositor.  The Depositor
will be the owner of the Group 4  Interest  Rate Cap Accounts  for federal tax purposes and the  Depositor
shall direct the Trust  Administrator in writing as to the investment of amounts  therein.  In the absence
of such  written  direction,  all funds in the Group 4  Interest  Rate Cap Accounts may be invested by the
Trust  Administrator  in the Wells Fargo  Advantage  Prime  Investment  Money Market Fund or any successor
fund. The Trust  Administrator  shall have no liability for losses on investments in Eligible  Investments
made pursuant to this  Section 4.08(c) (other  than as obligor on any such investments).  Upon termination
of the Trust Fund,  any amounts  remaining in the Group 4  Interest Rate Cap Accounts shall be distributed
to the Class 4-X Certificateholders.

(f)      The Trust  Administrator  is hereby  directed,  on or prior to the Closing Date, on behalf of the
Trust and the  Trustee,  to enter into the Group 4  Interest  Rate Cap  Agreements  for the benefit of the
Holders  of  the  Group 4  Certificates,  in  the  form  presented  to  it by  the  Depositor.  The  Trust
Administrator  shall not have any responsibility for the contents,  adequacy or sufficiency of the Group 4
Interest  Rate  Cap  Agreements,   including,  without  limitation,  any  representations  and  warranties
contained  therein.  The Trust  Administrator  shall  administer,  hold, and receive and make all payments
under the Group 4  Interest Rate Cap Agreements on behalf of the Trust and the Trustee in accordance  with
its terms and the provisions of this Agreement.

(g)      Upon any failure by the Group 4  Interest Rate Cap  Counterparty  to make, when due, any Transfer
of Eligible  Collateral,  Posted  Collateral or the Interest  Amount with respect to any Group 4  Interest
Rate Cap Agreement  (as such terms are defined in such Group 4  Interest  Rate Cap  Agreement),  the Trust
Administrator  shall deliver to the Group 4  Interest Rate Cap  Counterparty  the notice  contemplated  by
Paragraph 7(i)  of the related Credit  Support Annex attached to such Group 4  Interest Rate Cap Agreement
of the Group 4 Interest Rate Cap Counterparty's  failure to do so. The Trust  Administrator  shall deliver
such notice no later than 1:00 p.m.  eastern  time on the  Business  Day  immediately  following  any such
failure by the Group 4 Interest Rate Cap Counterparty.

SECTION 4.09.     Supplemental Interest Trust.

(a)      A separate trust is hereby established (the "Supplemental  Interest Trust"),  the corpus of which
shall be held by the  Supplemental  Interest  Trust Trustee,  in trust,  for the benefit of the holders of
the  Class 4-A-2  Certificates.  On the Closing  Date,  the  Supplemental  Interest  Trust  Trustee  shall
establish and maintain in its name, a separate  account for the benefit of the holders of the  Class 4-A-2
Certificates  (the  "Supplemental  Interest  Account").  The  Supplemental  Interest  Account  shall be an
Eligible  Account,  and funds on deposit  therein shall be held separate and apart from,  and shall not be
commingled  with,  any  other  moneys,   including,   without  limitation,   other  moneys  of  the  Trust
Administrator held pursuant to this Agreement.

(b)      The Trust  Administrator  shall deposit into the  Supplemental  Interest  Account the amounts set
forth in  Section 4.01(II)(a),  (b), (c) and (d). The  Supplemental  Interest  Trust Trustee shall deposit
into the  Supplemental  Interest  Account any Net Swap Payments  received from the Swap  Counterparty.  On
any Swap  Payment  Date on which a Net Swap  Payment is owed to the Swap  Counterparty,  the  Supplemental
Interest Trust Trustee shall withdraw from the  Supplemental  Interest Account an amount equal to such Net
Swap  Payment  and pay such  amount to the Swap  Counterparty.  On each Swap  Payment  Date on which a Net
Swap Payment is owed to the Trust Fund,  the  Supplemental  Interest Trust Trustee shall withdraw from the
Supplemental  Interest  Account an amount  equal to such Net Swap Payment and pay such amount to the Trust
Fund  for  distribution  on  the  related   Distribution   Date  in  accordance  with  the  provisions  of
subparagraph (f) of this Section 4.09.

(c)      Funds in the  Supplemental  Interest  Account  shall be invested in Eligible  Investments,  which
shall mature not later than the Business Day prior to the Swap Payment Date.  The  Depositor  shall direct
the  Supplemental  Interest Trust Trustee in writing as to the  investment of amounts in the  Supplemental
Interest  Account.  In the  absence of such  written  direction,  all funds in the  Supplemental  Interest
Account may be invested by the  Supplemental  Interest  Trust Trustee in the Wells Fargo  Advantage  Prime
Money  Market  Fund  or any  successor  fund.  The  Supplemental  Interest  Trust  Trustee  shall  have no
liability for losses an investments in Eligible Investments made pursuant to this  Section 4.09(c)  (other
than as obligor on any such  investments).  Any  earnings on such  amounts  shall be  distributed  on each
Distribution Date pursuant to paragraph (f) of this Section 4.09.

(d)      Upon  termination  of the Trust  Fund and after  payment  of any  moneys  to the  holders  of the
Class 4-A-2  Certificates as provided in paragraph (f) of this Section 4.09,  any amounts remaining in the
Supplemental  Interest  Account  after  payment  of  amounts  owing  to the  Swap  Counterparty  shall  be
distributed to the holder of the Class 4-X Certificates.

(e)      The Trust Administrator is hereby directed,  as Supplemental  Interest Trust Trustee,  and not in
its individual  capacity,  on or prior to the Closing Date, on behalf of the Supplemental  Interest Trust,
to enter into and assume the  obligations  under the Swap  Agreement  with the Swap  Counterparty  for the
benefit of the Holders of the  Class 4-A-2  Certificates,  in the form  presented to it by the  Depositor.
Neither the Trust  Administrator  nor the  Supplemental  Interest  Trust Trustee  shall,  individually  or
personally,  have any liability to perform any covenant  either  express or implied  contained in the Swap
Agreement and under no circumstance  shall the Trust  Administrator  be personally  liable for the payment
of any amounts  payable by the  Supplemental  Interest  Trust under the Swap  Agreement or any expenses of
the   Supplemental   Interest  Trust  or  be  liable  for  the  breach  or  failure  of  any   obligation,
representation,  warranty or covenant  made or  undertaken by the  Supplemental  Interest  Trust under the
Swap Agreement.  None of the Master  Servicer,  Trustee,  Trust  Administrator  or  Supplemental  Interest
Trust  Trustee shall have a duty to review or otherwise  determine the adequacy of the Swap  Agreement (or
any amendment or supplement thereto).

(f)      On each  Distribution  Date,  the Trust  Administrator  shall  distribute any amounts it receives
from the  Supplemental  Interest  Account in  respect of the  related  Net Swap  Payment  owed by the Swap
Counterparty,  to pay to the holders of the  Class 4-A-2  Certificates  an amount  equal to the product of
(a) the positive excess of the Formula Rate for the Class 4-A-2  Certificates for such  Distribution  Date
over the Net Funds Cap for such  Distribution  Date, (b) a fraction,  the numerator of which is the actual
number of days  elapsed  in the  related  Calculation  Period  and the  denominator  of which is 360,  and
(c) the Swap Notional Amount.  Any amounts in the Supplemental  Interest Account relating to such Net Swap
Payment remaining after  distribution to the holders of the Class 4-A-2  Certificates shall be distributed
to the holders of the  Class 4-X  Certificates.  On any  Distribution  Date,  any  amounts  that the Trust
Administrator  receives  from  the  Supplemental  Interest  Account  at any  time  since  the  immediately
preceding  Distribution  Date in  respect  of Net Swap  Payments  owed by the Swap  Counterparty  on prior
related Swap Payment Dates shall be, first,  distributed  to the holders of the  Class 4-A-2  Certificates
in reduction of any Basis Risk  Shortfalls for such Class,  until the amount of any Basis Risk  Shortfalls
due and owing for such Class and, second, distributed to the holders of the Class 4-X Certificates.

(g)      The  Supplemental  Interest  Trust  Trustee  shall  deliver to the Swap  Counterparty  the notice
contemplated  by  Paragraph 7(i)  of the Credit  Support Annex  attached to the Swap Agreement if the Swap
Counterparty  fails to make,  when due,  any Transfer of Eligible  Collateral,  Posted  Collateral  or the
Interest  Amount  (as such  terms  are  defined  in the Swap  Agreement)  required  to be made by the Swap
Counterparty.  The  Supplemental  Interest Trust Trustee shall deliver such notice no later than 1:00 p.m.
eastern time on the Business Day immediately following any such failure by the Swap Counterparty.

SECTION 4.10.     Rights of Swap Counterparty.

                  The Swap  Counterparty  shall be deemed a third-party  beneficiary  of this Agreement to
the same  extent as if it were a party  hereto and shall have the right to enforce  its rights  under this
Agreement.  For the protection and  enforcement of the provisions of this Section,  the Swap  Counterparty
shall be entitled to relief as can be given either at law or in equity.

SECTION 4.11.     Replacement Swap Counterparty.

(a)      In the event  that the  Supplemental  Interest  Trust  Trustee,  on  behalf  of the  Supplemental
Interest  Trust,  and at the  direction of the  Depositor,  enters into a  replacement  interest rate swap
agreement with a replacement swap  counterparty (the  "Replacement  Swap  Counterparty"),  then (a) to the
extent that the Supplemental  Interest Trust would be required to make a Swap  Termination  Payment to the
Swap  Counterparty and (b) to the extent the Replacement Swap  Counterparty  pays to assume the rights and
obligations  of  the  Swap  Counterparty  under  the  Swap  Agreement  (the  "Replacement  Payment"),  the
Supplemental  Interest  Trust  Trustee,  on  behalf  of the  Supplemental  Interest  Trust,  and the  Swap
Counterparty  agree that such Replacement  Payment shall be paid to the Swap  Counterparty and shall, only
to the extent actually paid by the Replacement  Swap  Counterparty  to the Swap  Counterparty,  constitute
satisfaction in full of the  obligations of the  Supplemental  Interest Trust to the Swap  Counterparty in
respect of the  assignment of the  outstanding  transaction  under the Swap  Agreement to the  Replacement
Swap  Counterparty  or the replacement of such  transaction  with the Replacement  Swap  Counterparty.  In
addition,  upon termination of the Swap  Counterparty and to the extent that the Swap  Counterparty  would
be required to make a Swap Termination  Payment to the Supplemental  Interest Trust, such Swap Termination
Payment  shall be deposited  into the  Supplement  Interest  Account and shall be used to make any upfront
payment required to be made to a Replacement Swap Counterparty.

(b)      Notwithstanding  anything to the contrary  contained herein, in the event that a replacement swap
agreement  is  not  obtained  within  30  days  after  receipt  by the  Trust  Administrator  of the  Swap
Termination  Payment paid by the terminated Swap Counterparty,  the Trust Administrator shall deposit such
Swap Termination  Payment into the Supplemental  Interest  Account and the Trust  Administrator  shall, on
each  Distribution  Date,  withdraw from such Supplemental  Interest  Account,  an amount equal to the Net
Swap Payment,  if any, that would have been paid to the  Supplemental  Interest Trust by the original Swap
Counterparty  (computed in accordance  with the terms of the original Swap  Agreement) and distribute such
amount in accordance with Section 4.01 of this Agreement.

                              ADVANCES BY THE MASTER SERVICER AND SERVICERS

SECTION 5.01.     Advances by the Master Servicer and Servicers.

                  With respect to the  Non-Designated  Mortgage Loans,  each Servicer shall deposit in the
related  Collection  Account as Advances an amount equal to all Scheduled  Payments  (with interest at the
Mortgage Rate less the Servicing Fee Rate) which were due on such  Non-Designated  Mortgage Loans serviced
by it during the applicable  Collection  Period and which were  delinquent at the close of business on the
immediately  preceding  Determination Date; provided,  however, that with respect to any Balloon Loan that
is  delinquent  on its  maturity  date,  a Servicer  shall not be required to advance the related  balloon
payment  but shall be required to continue to make  Advances in  accordance  with this  Section 5.01  with
respect to such Balloon Loan in an amount equal to an assumed  scheduled  payment that would  otherwise be
due based on the original  amortization  schedule for that  Mortgage  Loan (with  interest at the Mortgage
Rate less the  Servicing  Fee Rate).  Each  Servicer's  obligation to make such Advances as to any related
Non-Designated  Mortgage Loan shall continue  through the last Scheduled  Payment due prior to the payment
in full of such  Non-Designated  Mortgage  Loan, or through the date that the related  Mortgaged  Property
has, in the judgment of the related  Servicer,  been  completely  liquidated.  Each Servicer  shall not be
required to advance shortfalls of principal or interest resulting from the application of the Relief Act.

                  With respect to any  Non-Designated  Mortgage  Loan, to the extent  required by Accepted
Servicing  Practices,  the Master  Servicer  and each  Servicer  shall be  obligated  to make  Advances in
accordance with the provisions of this  Agreement;  provided,  however,  that such obligation with respect
to any related  Non-Designated  Mortgage Loan shall cease if the Master Servicer or a Servicer determines,
in its  reasonable  opinion,  that  Advances  with  respect  to  such  Non-Designated  Mortgage  Loan  are
Nonrecoverable  Advances.  In the event that the Master Servicer or such Servicer determines that any such
Advances  are  Nonrecoverable  Advances,  the Master  Servicer or such  Servicer  shall  provide the Trust
Administrator with a certificate signed by a Servicing Officer evidencing such determination.

                  With respect to any  Non-Designated  Mortgage  Loan, if the amount of Advances  received
from a Servicer is less than the amount  required to be advanced  by such  Servicer,  the Master  Servicer
shall be obligated to make a payment in an amount equal to such deficiency,  subject to any  determination
by the Master  Servicer  that any  portion of the  amount  required  to be  advanced  is a  Nonrecoverable
Advance.

                  With respect to any of the  Non-Designated  Mortgage Loans, if an Advance is required to
be made hereunder by a Servicer,  such Servicer shall on the Cash  Remittance  Date either  (i) deposit in
the  Collection  Account  from its own funds an amount  equal to such  Advance,  (ii) cause  to be made an
appropriate  entry in the records of the  Collection  Account  that funds in such  account  being held for
future  distribution or withdrawal have been, as permitted by this Section 5.01,  used by such Servicer to
make  such  Advance  or  (iii) make   Advances  in  the  form  of  any   combination  of  clauses  (i) and
(ii) aggregating  the amount of such Advance. Any such funds being held in a Collection Account for future
distribution  and so used  shall be  replaced  by such  Servicer  from its own  funds by  deposit  in such
Collection  Account  on or before any future  Distribution  Date in which such funds  would be due or from
other funds in such Collection Account being held for future distribution at that time.

                  With respect to any Designated  Mortgage  Loan, the Master  Servicer shall make Advances
as required by Section 3.20(b) of this Agreement.

                                                ARTICLE VI

                                             THE CERTIFICATES

SECTION 6.01.     The Certificates.

                  The  Certificates  shall be in  substantially  the forms set forth in  Exhibits A, B, C,
D-1,  D-2,  E, F and G hereto,  with  such  appropriate  insertions,  omissions,  substitutions  and other
variations  as are  required or permitted by this  Agreement or as may in the  reasonable  judgment of the
Trust  Administrator  or the Depositor be necessary,  appropriate  or convenient to comply,  or facilitate
compliance,  with  applicable  laws, and may have such letters,  numbers or other marks of  identification
and such  legends or  endorsements  placed  thereon  as may be  required  to comply  with the rules of any
securities exchange on which any of the Certificates may be listed, or as may,  consistently  herewith, be
determined by the officers executing such Certificates, as evidenced by their execution thereof.

                  Subject to  Section 11.03  respecting the final  distribution  on the  Certificates,  on
each Distribution  Date the Trust  Administrator  shall make  distributions to each  Certificateholder  of
record on the  preceding  Record Date either (x) by wire transfer in  immediately  available  funds to the
account of such holder at a bank or other  entity  having  appropriate  facilities  therefor,  if (i) such
Holder has so notified the Trust  Administrator  at least five Business  Days prior to the related  Record
Date and (ii) such  Holder shall hold (A) a Notional Amount  Certificate,  (B) 100% of the Class Principal
Balance  of  any  Class of   Certificates  or  (c) Certificates  of  any  Class with  aggregate  principal
Denominations  of not  less  than  $1,000,000  or  (y) by  check  mailed  by  first  class  mail  to  such
Certificateholder at the address of such holder appearing in the Certificate Register.

                  The definitive Certificates shall be printed,  typewritten,  lithographed or engraved or
produced by any  combination  of these  methods or may be produced in any other  manner  permitted  by the
rules of any  securities  exchange on which any of the  Certificates  may be listed,  all as determined by
the officers executing such Certificates, as evidenced by their execution thereof.

                  The  Certificates  shall be issuable in registered  form, in the minimum  denominations,
integral  multiples  in excess  thereof  (except  that one  Certificate  in each  Class may be issued in a
different  amount  which  must  be in  excess  of  the  applicable  minimum  denomination)  and  aggregate
denominations per Class set forth in the Preliminary Statement.

                  The  Certificates  shall be executed by manual or  facsimile  signature on behalf of the
Trust  Administrator by a Responsible  Officer.  Certificates  bearing the manual or facsimile  signatures
of individuals who were, at the time when such  signatures  were affixed,  authorized to sign on behalf of
the Trust Administrator shall bind the Trust  Administrator,  notwithstanding that such individuals or any
of them have ceased to be so authorized prior to the  authentication  and delivery of such Certificates or
did not hold such  offices  at the date of such  Certificate.  No  Certificate  shall be  entitled  to any
benefit under this  Agreement,  or be valid for any purpose,  unless there  appears on such  Certificate a
certificate  of  authentication  executed  by the  Trust  Administrator  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 6.02.     Registration of Transfer and Exchange of Certificates.

(a)      The Trust  Administrator  shall maintain,  or cause to be maintained,  a Certificate  Register in
which, subject to such reasonable  regulations as it may prescribe,  the Trust Administrator shall provide
for the  registration of Certificates  and of transfers and exchanges of Certificates as herein  provided.
Upon surrender for registration of transfer of any  Certificate,  the Trust  Administrator  shall execute,
authenticate  and  deliver,  in the name of the  designated  transferee  or  transferees,  one or more new
Certificates in like aggregate interest and of the same Class.

(b)      At the option of a  Certificateholder,  Certificates  may be exchanged for other  Certificates of
authorized  denominations  and the same aggregate  interest in the Trust Fund and of the same Class,  upon
surrender  of the  Certificates  to be exchanged  at the office or agency of the Trust  Administrator  set
forth  in  Section 6.06.   Whenever  any   Certificates  are  so  surrendered  for  exchange,   the  Trust
Administrator  shall  execute,  authenticate  and deliver  the  Certificates  which the  Certificateholder
making the exchange is entitled to receive.  Every  Certificate  presented or surrendered for registration
of transfer or exchange shall be accompanied by a written  instrument of transfer in form  satisfactory to
the Trust Administrator duly executed by the Holder thereof or his attorney duly authorized in writing.

(c)      No service charge to the  Certificateholders  shall be made for any  registration  of transfer or
exchange of  Certificates,  but payment of a sum sufficient to cover any tax or  governmental  charge that
may be imposed in connection with any transfer or exchange of Certificates may be required.

(d)      All  Certificates  surrendered  for  registration  of transfer and exchange shall be canceled and
subsequently  destroyed by the Trust Administrator in accordance with the Trust Administrator's  customary
procedures.

(e)      No transfer of any Private  Certificate  shall be made unless that  transfer is made  pursuant to
an effective  registration  statement under the 1933 Act and effective registration or qualification under
applicable  state securities  laws, or is made in a transaction  which does not require such  registration
or  qualification.  Except in connection  with any transfer of a Private  Certificate  by the Depositor to
any  affiliate  or any  transfer  of a Private  Certificate  from the  Depositor  or an  affiliate  of the
Depositor to an owner trust or other entity  established  by the  Depositor,  in the event that a transfer
is to be made in  reliance  upon an  exemption  from  the  1933 Act and  such  laws,  in  order to  assure
compliance  with the 1933 Act and such laws,  the  Certificateholder  desiring to effect such transfer and
such  Certificateholder's  prospective transferee shall each certify to the Trust Administrator in writing
the facts  surrounding  the transfer in  substantially  the form set forth in Exhibit L  (the  "Transferor
Certificate")  and  (i) deliver  a  letter  in  substantially  the form of  either  (A)  Exhibit M-1  (the
"Investment  Letter"),  provided that all of the Private  Certificates  of a Class shall be transferred to
one  investor or the  Depositor  otherwise  consents to such  transfer,  (B) Exhibit M-2  (the  "Rule 144A
Letter") or  (C) Exhibit M-3  (the  "Regulation S  Letter") or (ii) there  shall be delivered to the Trust
Administrator  at the  expense of the  transferor  an Opinion of Counsel  that such  transfer  may be made
pursuant  to an  exemption  from the 1933 Act.  The  Depositor  shall  provide  to any Holder of a Private
Certificate  and any  prospective  transferee  designated  by any such Holder,  information  regarding the
related  Certificates  and the Mortgage Loans and such other  information as shall be necessary to satisfy
the condition to eligibility set forth in  Rule 144A(d)(4)  or Regulation S,  as applicable,  for transfer
of any such  Certificate  without  registration  thereof  under the 1933 Act pursuant to the  registration
exemption  provided by  Rule 144A  or  Regulation S.  The Trust  Administrator  shall  cooperate  with the
Depositor in providing the information  referenced in the preceding  sentence,  including providing to the
Depositor such  information  regarding the  Certificates,  the Mortgage Loans and other matters  regarding
the Trust Fund as the  Depositor  shall  reasonably  request to meet its  obligation  under the  preceding
sentence.  Each Holder of a Private  Certificate  desiring to effect such transfer shall,  and does hereby
agree to,  indemnify  the Trust  Administrator,  the  Depositor,  the Seller,  the Master  Servicer,  each
Servicer and the Special  Servicer  against any liability that may result if the transfer is not so exempt
or is not made in accordance with such federal and state laws.

(f)      Except  in  connection  with any  transfer  of a  Private  Certificate  by the  Depositor  to any
affiliate or any transfer of a Private  Certificate  from the  Depositor or an affiliate of the  Depositor
to an owner trust or other  entity  established  by the  Depositor,  no  transfer  of an  ERISA-Restricted
Certificate  (except for the Residual  Certificates)  shall be made unless the Trust  Administrator  shall
have received in accordance  with  Exhibit M-1,  Exhibit M-2 or Exhibit M-3,  as applicable,  either (i) a
representation  letter from the  transferee of such  Certificate,  acceptable to and in form and substance
satisfactory to the Trust  Administrator,  to the effect that such  transferee is not an employee  benefit
plan or arrangement  subject to Section 406  of ERISA or  Section 4975  of the Code, or a person using the
assets of any such plan or  arrangement,  which  representation  letter  shall  not be an  expense  of the
Trustee,  the Trust  Administrator  or the Trust Fund,  (ii) if the purchaser is an insurance  company and
the  Certificate  has been the subject of an  ERISA-Qualifying  Underwriting,  a  representation  that the
purchaser is an  insurance  company  which is  purchasing  such  Certificates  with funds  contained in an
"insurance  company general  account" (as such term is defined in  Section V(e) of Prohibited  Transaction
Class Exemption 95-60 ("PTCE 95-60")) and that the purchase and holding of such  Certificates  are covered
under  Sections  I and III of PTCE  95-60  or  (iii) in  the case of any such  Certificate  presented  for
registration  in the name of an employee  benefit plan or  arrangement  subject to Section 406 of ERISA or
Section 4975 of the Code (or comparable provisions of any subsequent  enactments),  or a person using such
plan's or  arrangement's  assets,  an Opinion of Counsel  satisfactory to the Trust  Administrator  to the
effect that the purchase or holding of such Certificate will not result in prohibited  transactions  under
Section 406  of ERISA and/or  Section 4975  of the Code and will not subject the  Depositor,  the Trustee,
the Trust  Administrator,  the Master  Servicer  or any other  Servicer to any  obligation  in addition to
those  undertaken in this  Agreement,  which Opinion of Counsel shall not be an expense of such parties or
the Trust  Fund.  No  transfer  of a Residual  Certificate  shall be made  unless the Trust  Administrator
shall have received,  in accordance with Exhibit N,  a  representation  letter from the transferee of such
Certificate,  acceptable  to and in form and substance  satisfactory  to the Trust  Administrator,  to the
effect that such  transferee is not an employee  benefit plan or  arrangement  subject to  Section 406  of
ERISA or  Section 4975  of the Code, or a person using the assets of any such plan or  arrangement,  which
representation  letter  shall not be an  expense  of the  Trustee,  the Trust  Administrator  or the Trust
Fund.  In the event the  representations  referred  to in this  Section 6.02(f) are  not  furnished,  such
representations  shall be deemed to have been made to the trustee by the  transferee's  acceptance of such
ERISA-Restricted  Certificate  by any  beneficial  owner who purchases an interest in such  Certificate in
book-entry  form.  In the  event  that a  representation  is  violated,  or any  attempt  to  transfer  an
ERISA-Restricted  Certificate to a plan or arrangement or person using a plan's or arrangement's assets is
attempted  without the delivery to the Trust  Administrator of the Opinion of Counsel described above, the
attempted transfer or acquisition of such Certificate shall be void and of no effect.

(g)      Additional  restrictions on transfers of the Class AR and Class AR-L  Certificates  are set forth
below:

(i)      Each Person who has or who acquires any  ownership  interest in a Residual  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 Trust  Administrator or its
         designee under clause  (iii)(A) below to deliver  payments to a Person other than such Person and
         to  negotiate  the terms of any  mandatory  sale under clause  (iii)(B)  below and to execute all
         instruments  of transfer and to do all other things  necessary in connection  with any such sale.
         The  rights of each  Person  acquiring  any  ownership  interest  in a Residual  Certificate  are
         expressly subject to the following provisions:

(A)      Each Person  holding or  acquiring  any  ownership  interest in a Residual  Certificate  shall be
              other than a Disqualified  Organization and shall promptly notify the Trust Administrator of
              any change or impending change in its status as other than a Disqualified Organization.

(B)      In connection with any proposed transfer of any ownership  interest in a Residual  Certificate to
              a U.S. Person, the Trust  Administrator shall require delivery to it, and shall not register
              the transfer of a Residual  Certificate  until its receipt of (1) an affidavit and agreement
              (a "Transferee  Affidavit and  Agreement"  attached  hereto as Exhibit N)  from the proposed
              transferee, in form and substance satisfactory to the Trust Administrator,  representing and
              warranting,  among other things,  that it is not a non U.S. Person,  that such transferee is
              other than a Disqualified  Organization,  that it is not acquiring its ownership interest in
              a Residual  Certificate that is the subject of the proposed  Transfer as a nominee,  trustee
              or agent for any Person who is not other than a Disqualified Organization,  that for so long
              as it retains its ownership interest in a Residual Certificate,  it shall endeavor to remain
              other than a  Disqualified  Organization,  and that it has reviewed the  provisions  of this
              Section 6.02(g) and  agrees to be bound by them, and (2) a certificate,  attached  hereto as
              Exhibit O,  from  the  Holder  wishing  to  transfer  a  Residual  Certificate,  in form and
              substance satisfactory to the Trust Administrator,  representing and warranting, among other
              things,  that no  purpose of the  proposed  transfer  is to allow such  Holder to impede the
              assessment or collection of tax.

(C)      Notwithstanding  the delivery of a Transferee  Affidavit and  Agreement by a proposed  transferee
              under clause (B) above, if the Trust  Administrator  has actual  knowledge that the proposed
              transferee  is not other than a  Disqualified  Organization,  no  transfer  of an  ownership
              interest in a Residual Certificate to such proposed transferee shall be effected.

(D)      Each Person  holding or acquiring any ownership  interest in a Residual  Certificate  agrees,  by
              holding or  acquiring  such  ownership  interest,  to  require a  Transferee  Affidavit  and
              Agreement  from the other  Person to whom such Person  attempts to  transfer  its  ownership
              interest  and to  provide a  certificate  to the Trust  Administrator  in the form  attached
              hereto as Exhibit O.

(ii)     The Trust  Administrator  shall  register  the transfer of any  Residual  Certificate  only if it
         shall  have  received  the  Transferee  Affidavit  and  Agreement,  a  certificate  of the Holder
         requesting  such  transfer  in the  form  attached  hereto  as  Exhibit O  and all of such  other
         documents as shall have been  reasonably  required by the Trust  Administrator  as a condition to
         such registration.

(iii)    (A)  If any Disqualified  Organization shall become a Holder of a Residual Certificate,  then the
              last preceding Holder that was other than a Disqualified  Organization shall be restored, to
              the extent permitted by law, to all rights and obligations as Holder thereof  retroactive to
              the  date  of  registration  of  such  transfer  of such  Residual  Certificate.  If any non
              U.S. Person shall become a Holder of a Residual Certificate,  then the last preceding Holder
              that is a U.S. Person shall be restored,  to the extent  permitted by law, to all rights and
              obligations as Holder thereof  retroactive  to the date of  registration  of the transfer to
              such non U.S. Person of such Residual  Certificate.  If a transfer of a Residual Certificate
              is  disregarded  pursuant to the  provisions  of Treasury  Regulations  Section 1.860E-1  or
              Section 1.860G-3,  then  the  last  preceding  Holder  that was  other  than a  Disqualified
              Organization  shall  be  restored,  to the  extent  permitted  by  law,  to all  rights  and
              obligations as Holder thereof  retroactive to the date of  registration  of such transfer of
              such  Residual  Certificate.  The Trust  Administrator  shall be under no  liability  to any
              Person  for any  registration  of  transfer  of a Residual  Certificate  that is in fact not
              permitted by this  Section 6.02(g) 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 of a Residual  Certificate  shall
              become  a  Holder  of a  Residual  Certificate  in  violation  of the  restrictions  in this
              Section 6.02(g) and  to the extent  that the  retroactive  restoration  of the rights of the
              Holder of such Residual Certificate as described in clause (iii)(A)  above shall be invalid,
              illegal or  unenforceable,  then the Depositor  shall have the right,  without notice to the
              Holder or any prior Holder of such Residual  Certificate,  to sell such Residual Certificate
              to a purchaser  selected by the Depositor on such terms as the  Depositor  may choose.  Such
              purported   transferee  shall  promptly  endorse  and  deliver  a  Residual  Certificate  in
              accordance  with the  instructions  of the  Depositor.  Such  purchaser may be the Depositor
              itself  or  any  affiliate  of  the  Depositor.  The  proceeds  of  such  sale,  net  of the
              commissions  (which may include  commissions  payable to the  Depositor or its  affiliates),
              expenses  and taxes due,  if any,  shall be  remitted  by the  Depositor  to such  purported
              transferee.  The terms and  conditions  of any sale  under  this  clause  (iii)(B)  shall be
              determined in the sole  discretion of the Depositor,  and the Depositor  shall not be liable
              to any Person having an ownership  interest or a purported  ownership interest in a Residual
              Certificate as a result of its exercise of such discretion.

(iv)     The  Master  Servicer  and each  Servicer,  on  behalf  of the Trust  Administrator,  shall  make
         available,  upon  written  request  from the  Trust  Administrator,  all  information  reasonably
         available  to it that is  necessary to compute any tax imposed (A) as a result of the transfer of
         an  ownership  interest  in a  Residual  Certificate  to  any  Person  who is  not  other  than a
         Disqualified  Organization,  including the  information  regarding  "excess  inclusions"  of such
         Residual  Certificate  required  to be  provided  to the  Internal  Revenue  Service  and certain
         Persons as described in Treasury Regulation  Section 1.860D  1(b)(5),  and (B) as a result of any
         regulated  investment  company,  real estate  investment trust,  common trust fund,  partnership,
         trust,  estate or organizations  described in Section 1381 of the Code having as among its record
         holders  at any time any Person who is not other  than a  Disqualified  Organization.  Reasonable
         compensation  for  providing  such  information  may be  required  by the Master  Servicer or the
         related Servicer from such Person.

(v)      The  provisions  of  this  Section 6.02(g) set  forth  prior  to this  Section 6.02(g)(v) may  be
         modified,  added  to or  eliminated  by the  Depositor,  provided  that  there  shall  have  been
         delivered to the Trust Administrator the following:

(A)      written  notification  from each Rating Agency to the effect that the  modification,  addition to
              or  elimination of such  provisions  will not cause such Rating Agency to downgrade its then
              current rating of the Certificates; and

(B)      a  certificate  of the  Depositor  stating that the Depositor has received an Opinion of Counsel,
              in form and substance  satisfactory to the Depositor,  to the effect that such modification,
              addition  to or  elimination  of such  provisions  will not cause the Trust Fund to cease to
              qualify as a REMIC and will not create a risk that  (i) the  Trust Fund may be subject to an
              entity level tax caused by the transfer of a Residual  Certificate  to a Person which is not
              other than a Disqualified  Organization or (2) a Certificateholder or another Person will be
              subject to a REMIC related tax caused by the transfer of applicable Residual  Certificate to
              a Person which is not other than a Disqualified Organization.

(vi)     The following legend shall appear on each Residual Certificate:

              ANY RESALE,  TRANSFER OR OTHER  DISPOSITION OF THIS CERTIFICATE MAY BE MADE ONLY IF THE
              PROPOSED  TRANSFEREE  PROVIDES  A TRANSFER  AFFIDAVIT  TO THE  DEPOSITOR  AND THE TRUST
              ADMINISTRATOR  THAT (1) SUCH  TRANSFEREE  IS NOT (A) THE  UNITED  STATES,  ANY STATE OR
              POLITICAL SUBDIVISION THEREOF, ANY FOREIGN GOVERNMENT, ANY INTERNATIONAL  ORGANIZATION,
              OR ANY AGENCY OR INSTRUMENTALITY OF ANY OF THE FOREGOING,  (B) ANY ORGANIZATION  (OTHER
              THAN A COOPERATIVE  DESCRIBED IN  SECTION 521 OF THE CODE) WHICH IS EXEMPT FROM THE TAX
              IMPOSED  BY  CHAPTER 1 OF THE CODE  UNLESS  SUCH  ORGANIZATION  IS  SUBJECT  TO THE TAX
              IMPOSED  BY  SECTION  511 OF THE  CODE,  (C)  ANY  ORGANIZATION  DESCRIBED  IN  SECTION
              1381(a)(2)(C)  OF THE CODE (ANY SUCH PERSON  DESCRIBED  IN THE  FOREGOING  CLAUSES (A),
              (B), OR (C) BEING HEREINAFTER REFERRED TO AS A "DISQUALIFIED ORGANIZATION"),  OR (D) AN
              AGENT OF A DISQUALIFIED  ORGANIZATION  AND (2) NO PURPOSE OF SUCH TRANSFER IS TO ENABLE
              THE  TRANSFEROR TO IMPEDE THE  ASSESSMENT OR  COLLECTION OF TAX. SUCH  AFFIDAVIT  SHALL
              INCLUDE  CERTAIN  REPRESENTATIONS  AS  TO  THE  FINANCIAL  CONDITION  OF  THE  PROPOSED
              TRANSFEREE.  NOTWITHSTANDING  THE  REGISTRATION  IN  THE  CERTIFICATE  REGISTER  OF ANY
              TRANSFER, SALE OR OTHER DISPOSITION OF THIS CERTIFICATE TO A DISQUALIFIED  ORGANIZATION
              OR AN AGENT OF A DISQUALIFIED ORGANIZATION,  SUCH REGISTRATION SHALL BE DEEMED TO BE OF
              NO LEGAL  FORCE OR  EFFECT  WHATSOEVER  AND SUCH  PERSON  SHALL  NOT BE  DEEMED TO BE A
              CERTIFICATEHOLDER  FOR ANY  PURPOSE  HEREUNDER,  INCLUDING,  BUT NOT  LIMITED  TO,  THE
              RECEIPT OF  DISTRIBUTIONS  ON THIS  CERTIFICATE.  EACH  HOLDER OF THIS  CERTIFICATE  BY
              ACCEPTANCE OF THIS  CERTIFICATE  SHALL BE DEEMED TO HAVE CONSENTED TO THE PROVISIONS OF
              THIS PARAGRAPH.

(h)      The Trust  Administrator  shall have no  liability  to the Trust Fund  arising from a transfer of
any such  Certificate  in reliance upon a  certification,  ruling or Opinion of Counsel  described in this
Section 6.02;  provided,  however,  that the Trust  Administrator  shall not  register the transfer of any
Residual  Certificate  if it has  actual  knowledge  that  the  proposed  transferee  does  not  meet  the
qualifications of a permitted Holder of a Residual Certificate as set forth in this Section 6.02.

(i)      Each  Holder  of a  Class 4-A-2  Certificate  or any  interest  therein  shall be  deemed to have
represented,  by its acquisition or holding of such  certificate or any interest  therein,  that as of any
date prior to the termination of the Swap Agreement,  at least one of PTCE 84-14,  90-1,  91-38,  95-60 or
96-23  or  other  applicable  exemption  applies  to such  Holder's  right to  receive  payments  from the
Supplemental Interest Trust.

SECTION 6.03.     Mutilated, Destroyed, Lost or Stolen Certificates.

                  If (a) any  mutilated  Certificate  is surrendered  to the Trust  Administrator,  or the
Trust  Administrator  receives  evidence  to its  satisfaction  of the  destruction,  loss or theft of any
Certificate  and (b) there is delivered to each  Servicer,  the Trustee and the Trust  Administrator  such
security or indemnity as may be required by them to save each of them  harmless,  then,  in the absence of
notice to the Trustee and the Trust  Administrator  that such Certificate has been acquired by a protected
purchaser,  the Trust  Administrator  shall execute,  authenticate and deliver, in exchange for or in lieu
of any such  mutilated,  destroyed,  lost or  stolen  Certificate,  a new  Certificate  of like  tenor and
interest  in the  Trust  Fund.  In  connection  with  the  issuance  of any  new  Certificate  under  this
Section 6.03,  the Trust  Administrator  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 Trust  Administrator)  connected  therewith.  Any replacement  Certificate issued
pursuant to this  Section 6.03  shall constitute  complete and  indefeasible  evidence of ownership in the
Trust Fund, as if originally  issued,  whether or not the lost,  stolen or destroyed  Certificate shall be
found at any time.

SECTION 6.04.     Persons Deemed Owners.

                  Prior  to  due  presentation  of  a  Certificate  for  registration  of  transfer,  each
Servicer,  the Trust  Administrator,  and any agent of the  Master  Servicer  or any  Servicer,  the Trust
Administrator  may treat the  person in whose  name any  Certificate  is  registered  as the owner of such
Certificate  for the purpose of receiving  distributions  as provided in this  Agreement and for all other
purposes whatsoever,  and none of the Master Servicer or the Servicers,  the Trust Administrator,  nor any
agent of the Master Servicer or a Servicer or the Trust  Administrator  shall be affected by any notice to
the contrary.

SECTION 6.05.     Access to List of Certificateholders' Names and Addresses.

(a)      If three or more  Certificateholders  (i) request in writing from the Trust  Administrator a list
of the names and  addresses  of  Certificateholders,  (ii) state  that such  Certificateholders  desire to
communicate with other  Certificateholders  with respect to their rights under this Agreement or under the
Certificates  and  (iii) provide  a copy of the  communication  which such  Certificateholders  propose to
transmit,  then the Trust  Administrator  shall,  within  ten  Business  Days  after the  receipt  of such
request,  afford such  Certificateholders  access  during normal  business  hours to a current list of the
Certificateholders.  The  expense of  providing  any such  information  requested  by a  Certificateholder
shall be borne by the  Certificateholders  requesting such information and shall not be borne by the Trust
Administrator  or the Trustee.  Every  Certificateholder,  by receiving and holding a Certificate,  agrees
that the Trustee and the Trust  Administrator  shall not be held  accountable  by reason of the disclosure
of any such  information  as to the list of the  Certificateholders  hereunder,  regardless  of the source
from which such information was derived.

(b)      The Master  Servicer  and each  Servicer,  so long as it is a servicer  hereunder,  DLJMC and the
Depositor  shall have  unlimited  access to a list of the names and  addresses  of the  Certificateholders
which list shall be provided by the Trust Administrator promptly upon request.

SECTION 6.06.     Maintenance of Office or Agency.

                  The Trust  Administrator  shall  maintain  or cause to be  maintained  at its expense an
office or offices or agency or agencies in Minneapolis,  Minnesota where  Certificates  may be surrendered
for  registration  of  transfer  or  exchange  and  where  notices  and  demands  to  or  upon  the  Trust
Administrator  in respect of the Certificates  and this Agreement may be served.  The Trust  Administrator
initially  designates its Corporate Trust Office as its office for such purpose.  The Trust  Administrator
shall give  prompt  written  notice to the  Certificateholders  of any change in the  location of any such
office or agency.

SECTION 6.07.     Book Entry Certificates.

                  Notwithstanding  the foregoing,  the Book-Entry  Certificates,  upon original  issuance,
shall  be  issued  in the  form  of one or  more  typewritten  Certificates  representing  the  Book-Entry
Certificates,  to be delivered to DTC, the initial  Clearing  Agency,  by, or on behalf of, the Depositor.
The  Book-Entry  Certificates  shall  initially be registered on the  Certificate  Register in the name of
Cede & Co., the nominee of DTC, as the initial  Clearing Agency,  and no Beneficial  Holder will receive a
definitive  certificate  representing such Beneficial  Holder's  interest in the  Certificates,  except as
provided  in  Section 6.09.  Unless  and until  definitive,  fully  registered  Certificates  ("Definitive
Certificates") have been issued to the Beneficial Holders pursuant to Section 6.09:

(a)      the  provisions  of this  Section 6.07  shall be in full  force and  effect  with  respect to the
Book-Entry Certificates;

(b)      the  Depositor  and the Trust  Administrator  may deal with the Clearing  Agency for all purposes
with respect to the Book-Entry  Certificates  (including the making of distributions on such Certificates)
as the sole Holder of such Certificates;

(c)      to the extent that the  provisions of this  Section 6.07  conflict  with any other  provisions of
this Agreement, the provisions of this Section 6.07 shall control; and

(d)      the rights of the  Beneficial  Holders of the  Book-Entry  Certificates  shall be exercised  only
through the Clearing  Agency and the  Participants  and shall be limited to those  established  by law and
agreements  between such Beneficial  Holders and the Clearing Agency and/or the Participants.  Pursuant to
the Depository  Agreement,  unless and until Definitive  Certificates are issued pursuant to Section 6.09,
the  initial  Clearing  Agency  will make  book-entry  transfers  among the  Participants  and receive and
transmit  distributions  of  principal  and  interest  on the  related  Book-Entry  Certificates  to  such
Participants.

                  For purposes of any provision of this  Agreement  requiring or  permitting  actions with
the consent of, or at the  direction of,  Holders of the  Book-Entry  Certificates  evidencing a specified
percentage of the aggregate unpaid principal  amount of such  Certificates,  such direction or consent may
be  given by the  Clearing  Agency  at the  direction  of  Beneficial  Holders  owning  such  Certificates
evidencing the requisite  percentage of principal  amount of such  Certificates.  The Clearing  Agency may
take conflicting  actions with respect to the Book-Entry  Certificates to the extent that such actions are
taken on behalf of the Beneficial Holders.

SECTION 6.08.     Notices to Clearing Agency.

                  Whenever  notice or other  communication  to the Holders of Book-Entry  Certificates  is
required under this  Agreement,  unless and until  Definitive  Certificates  shall have been issued to the
related Certificateholders  pursuant to Section 6.09,  the Trust Administrator shall give all such notices
and  communications  specified  herein  to be given  to  Holders  of the  Book-Entry  Certificates  to the
Clearing  Agency  which  shall  give such  notices  and  communications  to the  related  Participants  in
accordance with its applicable rules, regulations and procedures.

SECTION 6.09.     Definitive Certificates.

                  If (a) the  Depositor  advises  the Trust  Administrator  in writing  that the  Clearing
Agency is no longer  willing or able to  properly  discharge  its  responsibilities  under the  Depository
Agreement  with respect to the  Certificates  and the Trust  Administrator  or the  Depositor is unable to
locate a  qualified  successor,  (b) the  Depositor,  with the  consent  of the  applicable  Participants,
advises  the Trust  Administrator  in writing  that it elects to  terminate  the  book-entry  system  with
respect to the  Book-Entry  Certificates  through the Clearing  Agency or (c) after  the  occurrence of an
Event of Default,  Holders of Book-Entry  Certificates  evidencing  not less than 66-2/3% of the aggregate
Class Principal  Balance of the Book-Entry  Certificates  advise the Trust  Administrator  in writing that
the  continuation  of a  book-entry  system with  respect to the such  Certificates  through the  Clearing
Agency is no longer  in the best  interests  of the  Holders  of such  Certificates  with  respect  to the
Book-Entry  Certificates and the applicable Participants consent, the Trust Administrator shall notify all
Holders of such  Certificates  of the  occurrence  of any such event and the  availability  of  Definitive
Certificates.  Upon surrender to the Trust  Administrator  of such  Certificates  by the Clearing  Agency,
accompanied  by  registration   instructions  from  the  Clearing  Agency  for  registration,   the  Trust
Administrator  shall authenticate and deliver the Definitive  Certificates.  Neither the Depositor nor the
Trust  Administrator  shall be liable for any delay in delivery of such  instructions and may conclusively
rely on, and shall be  protected  in relying  on,  such  instructions.  Upon the  issuance  of  Definitive
Certificates all references  herein to obligations  imposed upon or to be performed by the Clearing Agency
shall be deemed to be imposed upon and  performed  by the Trust  Administrator,  to the extent  applicable
with respect to such Definitive  Certificates,  and the Trust Administrator shall recognize the Holders of
Definitive Certificates as Certificateholders hereunder.

                                             ARTICLE VII

                                  THE DEPOSITOR, THE SELLER, THE MASTER

                  The Depositor,  the Seller, the Master Servicer,  each Servicer and the Special Servicer
shall be liable under this  Agreement to any other party to this  Agreement,  including  the  liability of
each  Servicer  to the Master  Servicer  in  accordance  herewith  only to the  extent of the  obligations
specifically and respectively imposed upon and undertaken by them herein.

SECTION 7.02.     Merger or Consolidation of the Seller, the Depositor, the Master Servicer, the
                                            Servicers or the Special Servicer.

                  Subject to the immediately succeeding paragraph,  the Depositor,  the Seller, the Master
Servicer,  each Servicer and the Special  Servicer shall each do or cause to be done all things  necessary
to  preserve  and keep in full  force and  effect  its  existence,  rights  and  franchises  (charter  and
statutory) and shall each obtain and preserve its  qualification  to do business as a foreign  corporation
in each  jurisdiction  in which such  qualification  is or shall be  necessary to protect the validity and
enforceability  of this  Agreement,  or any of the  Mortgage  Loans and to perform its  respective  duties
under this Agreement.

                  Any Person into which the Depositor,  the Seller,  the Master Servicer,  any Servicer or
the  Special  Servicer  may be  merged  or  consolidated,  or any  Person  resulting  from any  merger  or
consolidation  to which the  Depositor,  the  Seller,  the Master  Servicer,  any  Servicer or the Special
Servicer shall be a party,  or any Person  succeeding to the business of the Depositor,  the Seller or any
Servicer,  shall be the  successor  of the  Depositor,  the Seller or such  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 the successor
or surviving Person to the Master  Servicer,  any such Servicer or the Special Servicer shall be qualified
to sell mortgage loans to, and to service mortgage loans on behalf of, FNMA or FHLMC.

                  Notwithstanding  anything else in this  Section 7.02  or in  Section 7.04  hereof to the
contrary,  the  Master  Servicer  or a  Servicer  may  assign  its  rights  and  delegate  its  duties and
obligations under this Agreement;  provided,  however, that the Master Servicer or such Servicer gives the
Depositor,  the  Trustee  and the  Trust  Administrator  notice  of such  assignment;  provided,  further,
(a) that such  purchaser or transferee  accepting such  assignment and delegation  shall be an institution
that is a FNMA and FHLMC  approved  seller/servicer  in good  standing,  which has a net worth of at least
$15,000,000,  and which is willing to service the  Mortgage  Loans and (b) such  purchaser  or  transferee
executes and delivers to the Depositor,  the Trustee and the Trust  Administrator  an agreement  accepting
such  delegation  and  assignment,  which  contains an  assumption  by such Person of the rights,  powers,
duties,  responsibilities,  obligations and liabilities of the Master Servicer or such Servicer, with like
effect as if originally  named as a party to this Agreement;  provided,  further,  that each of the Rating
Agencies  acknowledge that its rating of the Certificates in effect  immediately  prior to such assignment
will not be qualified or reduced as a result of such  assignment and  delegation.  In the case of any such
assignment and  delegation,  the Master  Servicer or such Servicer shall be released from its  obligations
under this Agreement  (except as provided above),  except that the Master Servicer or the related Servicer
shall  remain  liable  for all  liabilities  and  obligations  incurred  by it as the Master  Servicer  or
Servicer  hereunder  prior to the  satisfaction  of the  conditions to such  assignment and delegation set
forth in the preceding sentence.

SECTION 7.03.     Limitation on Liability of the Seller, the Depositor, the Master Servicer, the
                                            Servicers, the Special Servicer and Others.

                  None of the  Depositor,  the Master  Servicer,  any  Servicer,  the Seller,  the Special
Servicer, nor any of the directors,  officers,  employees or agents of the Depositor, the Master Servicer,
any Servicer,  the Seller or the Special  Servicer shall be under any liability to the  Certificateholders
for any action  taken or for  refraining  from the taking of any  action 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,  any Servicer,  the Seller or the Special Servicer against any breach of
representations  or  warranties  made by it herein or protect  the  Depositor,  the Master  Servicer,  any
Servicer,  the Seller or the Special  Servicer or any such director,  officer,  employee or agent from any
liability  which  would  otherwise  be  imposed by  reasons  of  willful  misfeasance,  bad faith or gross
negligence  in the  performance  of duties or by reason of reckless  disregard of  obligations  and duties
hereunder.  The Depositor,  the Master  Servicer,  any Servicer,  the Seller and the Special  Servicer and
any director,  officer,  employee or agent of the Depositor, the Master Servicer, any Servicer, the Seller
or the Special  Servicer may rely in good faith on any document of any kind prima facie properly  executed
and  submitted  by any  Person  respecting  any  matters  arising  hereunder.  The  Depositor,  the Master
Servicer, any Servicer, the Seller and the Special Servicer and any director,  officer,  employee or agent
of the  Depositor,  the Master  Servicer,  any  Servicer,  the  Seller or the  Special  Servicer  shall be
indemnified  by the Trust Fund and held  harmless  against  any loss,  liability  or expense  incurred  in
connection  with any legal action  relating to this  Agreement or the  Certificates,  other than any loss,
liability  or expense  incurred by reason of willful  misfeasance,  bad faith or gross  negligence  in the
performance of duties  hereunder or by reason of reckless  disregard of obligations and duties  hereunder.
None of the Depositor,  the Master  Servicer,  any Servicer,  the Seller or the Special  Servicer shall be
under any  obligation to appear in,  prosecute or defend any legal action that is not  incidental to their
respective  duties  hereunder  and which in its  opinion  may  involve  it in any  expense  or  liability;
provided,  however,  that the  Depositor,  the Master  Servicer,  any Servicer,  the Seller or the Special
Servicer  may in its  discretion  undertake  any such action that it may deem  necessary  or  desirable in
respect of this  Agreement  and the rights and duties of the parties  hereto and interests of the Trustee,
the Trust Administrator and the  Certificateholders  hereunder;  provided,  however, that in the event the
related  Servicer agrees,  at the request of the Seller,  to act on behalf of the Seller in any dispute or
litigation  that  is  not  incidental  to  such  Servicer's  duties  hereunder  and  that  relates  to the
origination  of a Mortgage  Loan,  the Seller shall pay all expenses  associated  with the  management and
defense of such claim.  Anything in this  Agreement  to the  contrary  notwithstanding,  in no event shall
the  Master  Servicer,  any  Servicer  or  the  Special  Servicer  be  liable  for  special,  indirect  or
consequential loss or damage of any kind whatsoever  (including but not limited to lost profits),  even if
the Master  Servicer,  the related  Servicer or the Special Servicer has been advised of the likelihood of
such loss or damage and regardless of the form of action.

SECTION 7.04.     Master Servicer and Servicer Not to Resign; Transfer of Servicing.

(a)      Neither  the Master  Servicer  nor any  Servicer  shall  resign from the  obligations  and duties
hereby imposed on it except  (i) upon  appointment of a successor  master  servicer or successor  servicer
and  receipt by the Trustee and the Trust  Administrator  of a letter from each Rating  Agency that such a
resignation  and  appointment  will not result in a downgrading  of the rating of any of the  Certificates
related to the applicable  Mortgage Loans,  or (ii) upon  determination  that its duties  hereunder are no
longer  permissible  under  applicable  law.  Any such  determination  under  clause  (ii) permitting  the
resignation  of the Master  Servicer  or a Servicer  shall be  evidenced  by an Opinion of Counsel to such
effect delivered to the Trustee and the Trust  Administrator.  No such resignation  shall become effective
until the successor  master servicer or successor  servicer shall have assumed the Master Servicer or such
Servicer's, as applicable,  responsibilities,  duties, liabilities and obligations hereunder in accordance
with Section 8.02 hereof.

(b)      Notwithstanding  the  foregoing,  at DLJMC's  request,  so long as it is the owner of the related
servicing  rights,  the Master  Servicer or SPS shall  resign,  upon the selection  and  appointment  of a
successor  master  servicer or servicer,  as  applicable;  provided that DLJMC delivers to the Trustee and
the Trust  Administrator the letter required in  Section 7.04(a)(i) above.  Notwithstanding the foregoing,
in the event that the Master Servicer is appointed as the successor  servicer to SPS, the  requirements of
Section 7.04(a)(i) shall  be waived.  In  connection  with the  foregoing,  unless  otherwise  directed by
DLJMC in  writing on or prior to the first day of the second  month  following  the  Closing  Date,  DLJMC
hereby  directs SPS to resign as Servicer  hereunder  and appoints the Master  Servicer to service the SPS

In connection  with its  resignation,  SPS hereby agrees to deliver to the Master  Servicer on the date of
its  resignation  a schedule  setting  forth all of the SPS  Mortgage  Loans as of such  date.  The Master
Servicer  agrees  that,  as of the first day of the third  month  following  the  Closing  Date,  it shall
service the SPS  Serviced  Mortgage  Loans,  and that such loans  shall  constitute  Wells Fargo  Serviced
Mortgage Loans, in accordance with the terms of this Agreement.  If the Master Servicer  resigns  pursuant
to this  Section 7.04(b),  DLJMC shall pay the Master  Servicer an amount  equal to the product of (a) the
Stated Principal Balance of all of the Mortgage Loans then outstanding and (b) 0.02%.

(c)      Notwithstanding  the  foregoing,  if the Trust  Administrator  shall for any  reason no longer be
Trust Administrator  hereunder,  at DLJMC's request,  the Master Servicer shall resign, upon the selection
and  appointment  of a successor  master  servicer;  provided  that DLJMC  delivers to the Trustee and the
Trust Administrator the letter required in Section 7.04(a)(i) above.

(d)      Notwithstanding  the foregoing,  at DLJMC's request,  the Special Servicer shall resign, upon the
selection and appointment of a successor  special  servicer by DLJMC;  provided that DLJMC delivers to the
Trustee and the Trust Administrator the letter required in Section 7.04(a)(i) above.

SECTION 7.05.     Master Servicer, Seller and Servicers May Own Certificates.

                  Each of the Master Servicer,  the Seller,  the Special Servicer and each Servicer in its
individual or any other capacity may become the owner or pledgee of  Certificates  with the same rights as
it would have if it were not the Master Servicer, the Seller, the Special Servicer or a Servicer.

(d)      a decree  or order of a court or agency  or  supervisory  authority  having  jurisdiction  in the
premises for the  appointment of a conservator or receiver or liquidator in any  insolvency,  readjustment
of debt,  marshalling  of  assets  and  liabilities  or  similar  proceedings,  or for the  winding-up  or

proceedings  of or relating to the Master  Servicer or such  Servicer or all or  substantially  all of the
property of the Master Servicer or such Servicer; or

(f)      the  Master  Servicer  or a  Servicer  shall  admit in  writing  its  inability  to pay its debts

downgraded to "below  average"  status by one or more of the Rating  Agencies  rating the  Certificates or
(b) one or more Classes of the  Certificates are downgraded or placed on negative watch due in whole or in
part to the performance or master servicing of the Master Servicer;

(k)      any failure by an applicable  Servicer to (a) remit payment of an Assigned  Prepayment Premium to
the  Collection  Account or (b) remit  funds in the amount equal to an Assigned  Prepayment  Premium which
the  applicable  Servicer  has failed to  collect,  in each case as required  pursuant to this  Agreement,
which  failure  continues  unremedied  for a period of one Business Day after the date upon which  written
notice of such failure,  requiring  the same to be remedied,  shall have been given to the Servicer by the
Trust Administrator, the Master Servicer, the Trustee or the Depositor; or

(l)      Any failure by the Master Servicer or a Servicer to comply with the provisions of Article XIII.

                  If an Event of Default  due to the  actions or  inaction  of the  Master  Servicer  or a
Servicer  described in clauses  (a) through (f)  and (l) of this  Section 8.01  shall occur,  then, and in
each and every such case,  so long as such Event of Default  shall not have been  remedied,  (i) the Trust
Administrator  shall at the direction of the Trustee or the Holders of  Certificates  evidencing  not less
than 25% of the Voting Rights evidenced by the  Certificates,  by notice in writing to the Master Servicer
or such Servicer  (with a copy to the Rating  Agencies),  terminate all of the rights and  obligations  of
the Master  Servicer  or such  Servicer  under this  Agreement  (other than  rights to  reimbursement  for
Advances and  Servicing  Advances  previously  made,  as provided in  Section 3.08)  and  (ii) the  Master
Servicer  may, if such Event of Default is due to the  actions or  inactions  of a Servicer,  by notice in
writing  to  such  Servicer  (with  a copy  to the  Rating  Agencies),  terminate  all of the  rights  and
obligations  of such Servicer under this Agreement  (other than rights to  reimbursement  for Advances and
Servicing Advances previously made, as provided in Section 3.08).

                  If an Event of Default  described in clause (g) shall occur,  (i) if the Master Servicer
has failed to make any  Advance,  the  Trustee,  and (ii) if any  Servicer has failed to make any Advance,
the Master  Servicer,  shall  prior to the next  Distribution  Date,  immediately  make such  Advance  and
terminate  the rights and  obligations  of the Master  Servicer or  applicable  Servicer,  as  applicable,
hereunder  and  succeed  to the  rights  and  obligations  of the Master  Servicer  or such  Servicer,  as
applicable,  hereunder  pursuant  to  Section 8.02,  including  the  obligation  to make  Advances on such
succeeding  Distribution  Date  pursuant  to the terms  hereof.  No Event of Default  with  respect to the
Master  Servicer or a Servicer  shall affect the rights or duties of any other  Servicer or  constitute an
Event of Default as to any other Servicer.

                  If an Event of Default  described in clause (h), (i) or (k) occurs,  the Master Servicer
shall at the direction of DLJMC,  by notice in writing to such  Servicer,  terminate all of the rights and

Servicing  Advances  previously made, as provided in Section 3.08) and shall appoint as successor Servicer
the entity selected by DLJMC in accordance with  Section 8.02;  provided that DLJMC shall first furnish to

result in a downgrading of the rating of any of the Certificates.

                  If an Event of  Default  described  in  clause  (k)  occurs,  the  Trustee  shall at the
direction  of DLJMC,  by notice in  writing  to the  Master  Servicer,  terminate  all of the  rights  and
obligations of the Master Servicer under this Agreement (other than rights to  reimbursement  for Advances
previously  made, as provided in  Section 3.08)  and shall appoint as successor Master Servicer the entity
selected  by DLJMC in  accordance  with  Section 8.02;  provided  that DLJMC  shall  first  furnish to the
Trustee a letter  from each Rating  Agency that the  appointment  of such  successor  will not result in a
downgrading of the rating of any of the Certificates.

                  No Event of Default with  respect to the  Servicer  shall affect the rights or duties of
the Master Servicer or constitute an Event of Default as to the Master Servicer.

SECTION 8.02.     Master Servicer or Trust Administrator to Act; Appointment of Successor.

                  On and  after  the  time  the  Master  Servicer  or a  Servicer  receives  a  notice  of
termination  pursuant to Section 8.01  hereof or resigns pursuant to Section 7.04  hereof,  subject to the
provisions  of  Section 3.04  hereof,  the  Trustee  (in the case of the  Master  Servicer)  or the  Trust
Administrator  shall be the  successor  in all  respects  to the  Master  Servicer  or such  Servicer,  as
applicable,  in its capacity as servicer  under this  Agreement and with respect to the  transactions  set
forth or  provided  for herein and shall be subject to all the  responsibilities,  duties and  liabilities
relating  thereto  placed  on the  Master  Servicer  or such  Servicer,  as  applicable,  by the terms and
provisions  hereof;  provided,  that the  Trustee,  the Trust  Administrator  or the Master  Servicer,  as
applicable,  shall not be deemed to have made any  representation or warranty as to any Mortgage Loan made
by the  Master  Servicer  or any  Servicer,  as  applicable,  and  shall not  effect  any  repurchases  or
substitutions  of any Mortgage Loan;  provided,  further,  that it is understood and  acknowledged  by the
parties  hereto that there will be a full period of  transition  (not to exceed  ninety (90) days)  before
the actual  servicing  functions  of any  Servicer  can be fully  transferred  to Wells Fargo as successor
Servicer;  provided,  further,  that during such period of transition Wells Fargo, as successor  Servicer,
shall  continue  to make all  required  Compensating  Interest  Payments  and  Advances.  As  compensation
therefor,  the Trustee, the Trust Administrator or the Master Servicer,  as applicable,  shall be entitled
to all funds  relating to the Mortgage Loans that the Master  Servicer or related  Servicer (the "Replaced
Servicer") would have been entitled to charge to the related  Collection  Account if the Replaced Servicer
had  continued  to act  hereunder  (except  that  the  Replaced  Servicer  shall  retain  the  right to be
reimbursed for advances  (including,  without  limitation,  Advances and Servicing  Advances)  theretofore
made by the Replaced  Servicer  with respect to which it would be entitled to be reimbursed as provided in
Section 3.08  if it had not  been so  terminated  or  resigned).  Notwithstanding  the  foregoing,  if the
Trustee,  the Trust  Administrator  or the Master Servicer,  as applicable,  has become the successor to a
Replaced  Servicer,  in accordance with this  Section 8.02,  the Trustee,  the Trust  Administrator or the
Master Servicer,  as applicable,  may, if it shall be unwilling to so act, or shall, if it is unable to so
act,  appoint,  or petition a court of competent  jurisdiction to appoint,  any established  mortgage loan
servicing  institution,  the appointment of which does not adversely affect the then current rating of the
Certificates,  as the  successor to the Master  Servicer or a Servicer,  as  applicable,  hereunder in the
assumption of all or any part of the  responsibilities,  duties or liabilities  of the Master  Servicer or
such Servicer,  as applicable,  provided that such  successor to the Master  Servicer or the Servicer,  as
applicable,  shall not be deemed to have made any  representation or warranty as to any Mortgage Loan made
by the Master  Servicer or the related  Servicer,  as  applicable.  Pending  appointment of a successor to
the Master Servicer or a Servicer, as applicable,  hereunder,  the Trustee, the Trust Administrator or the
Master Servicer,  as applicable,  unless such party is prohibited by law from so acting, shall act in such
capacity as provided herein.  In connection with such appointment and assumption,  the Trustee,  the Trust
Administrator or the Master Servicer,  as applicable,  may make such  arrangements for the compensation of
such  successor  out of  payments  on  Mortgage  Loans as it and such  successor  shall  agree;  provided,
however,  that  no such  compensation  shall  be in  excess  of  that  permitted  the  Replaced  Servicer,
hereunder.  The  Trustee,  the  Trust  Administrator  or the  Master  Servicer,  as  applicable,  and such
successor  shall take such action,  consistent  with this  Agreement,  as shall be necessary to effectuate
any such  succession.  None of the Trustee,  the Trust  Administrator,  the Master  Servicer nor any other
successor  servicer  shall be deemed to be in default  hereunder by reason of any failure to make,  or any
delay in making,  any  distribution  hereunder or any portion  thereof caused by the failure of a Replaced
Servicer to deliver, or any delay in delivering, cash, documents or records to it.

                  A Replaced Servicer that has been terminated  shall, at the request of the Trustee,  the
Trust  Administrator or the Master Servicer,  as applicable,  but at the expense of such Replaced Servicer
deliver to the assuming party all documents and records  relating to the applicable  Mortgage Loans and an
accounting  of amounts  collected  and held by it and otherwise  use  commercially  reasonable  efforts to
effect the orderly and  efficient  transfer and  assignment of such  servicing,  but only to the extent of
the Mortgage Loans serviced thereunder,  to the assuming party.  Notwithstanding  anything to the contrary
contained  herein,  the  termination  of  a  Servicer  under  this  Agreement  shall  not  extend  to  any
Sub-Servicer  meeting the  requirements of  Section 3.02(a) and  otherwise  servicing the related Mortgage
Loans in accordance with the servicing provisions of this Agreement.

                  The Master  Servicer and each Servicer  shall  cooperate  with the Trustee and the Trust
Administrator  and  any  successor  servicer  in  effecting  the  termination  of  a  Replaced  Servicer's
responsibilities  and rights hereunder,  including without limitation,  the transfer to such successor for
administration  by it of all cash  amounts  which shall at the time be  credited  by such  Servicer to the
applicable Collection Account or thereafter received with respect to the Mortgage Loans.

                  None of the Trustee,  the Trust  Administrator nor any other successor servicer shall be
deemed  to be in  default  hereunder  by reason  of any  failure  to make,  or any  delay in  making,  any
distribution  hereunder or any portion  thereof  caused by (a) the  failure of the Master  Servicer or any
Servicer to (i) deliver,  or any delay in delivering,  cash, documents or records to it, or (ii) cooperate
as  required  by  this  Agreement,  or  (b) restrictions   imposed  by  any  regulatory  authority  having
jurisdiction over the Master Servicer or the related Servicer.

                  Any  successor  to a  Servicer  as  servicer  shall  during  the term of its  service as
servicer  maintain in force the policy or policies that such Servicer is required to maintain  pursuant to
Section 3.09(b) hereof.

                  If a  Servicer  that  has  been  terminated  fails  to  pay  all  costs  related  to the
transition  of  servicing  to the  successor  Servicer,  the  successor  Servicer  shall  be  entitled  to
reimbursement of those amounts from the Trust.

                  In connection  with the  termination  or  resignation  of a Servicer  hereunder,  either
(i) the  successor  Servicer,  including  the Trust  Administrator  or Master  Servicer  if either of such
parties is acting as successor  Servicer,  shall represent and warrant that it or an affiliate is a member
of MERS in good  standing  and  shall  agree  to  comply  in all  material  respects  with the  rules  and
procedures of MERS in  connection  with the servicing of the related  Mortgage  Loans that are  registered
with MERS,  or (ii) the  Replaced  Servicer,  at its sole  expense,  shall  cooperate  with the  successor
Servicer  either (x) in  causing MERS to execute and deliver an Assignment of Mortgage in recordable  form
to  transfer  the  Mortgage  from MERS to the  Trustee  and to execute  and  deliver  such other  notices,
documents  and other  instruments  as may be necessary or desirable to effect a transfer of such  Mortgage
Loan or servicing of such Mortgage Loan on the MERS® System to the  successor  Servicer or (y) in  causing
MERS to designate on the MERS® System the  successor  Servicer as the servicer of such  Mortgage  Loan (at
the cost and expense of the  successor  Servicer to the extent such costs relate to the  qualification  of
such  successor  Servicer  as a  member  of  MERS,  otherwise  at the cost  and  expense  of the  Replaced
Servicer).  The Replaced  Servicer shall file or cause to be filed any such  assignment in the appropriate
recording  office.  The  successor  Servicer  shall cause such  assignment  to be delivered to the Trustee
promptly  upon  receipt of the original  with  evidence of  recording  thereon or a copy  certified by the
public recording office in which such assignment was recorded.

SECTION 8.03.     Notification to Certificateholders.

(a)      Upon any  termination or appointment of a successor to the Master  Servicer or any Servicer,  the
Trust Administrator shall give prompt written notice thereof to the Seller and the  Certificateholders  at
their  respective  addresses  appearing in the  Certificate  Register and to the Rating  Agencies,  or, as
applicable, the Master Servicer shall give prompt written notice thereof to the Trust Administrator.

(b)      Within two Business Days after the  occurrence of any Event of Default,  the Trust  Administrator
shall transmit by mail to the Seller and all  Certificateholders,  and the Rating  Agencies notice of each
such Event of Default  hereunder  known to the Trust  Administrator,  unless  such Event of Default  shall
have been cured or waived.

SECTION 8.04.     Waiver of Events of Default.

                  The Holders  representing at least 66% of the Voting Rights of Certificates  affected by
a default or Event of Default  hereunder  may waive any  default or Event of Default;  provided,  however,
that (a) a  default or Event of Default  under clause (g) of  Section 8.01  may be waived,  only by all of
the Holders of  Certificates  affected by such default or Event of Default and (b) no  waiver  pursuant to
this   Section 8.04   shall   affect   the   Holders   of   Certificates   in  the  manner  set  forth  in
Section 12.01(b)(i),  (ii) or (iii).  Upon any such waiver of a default or Event of Default by the Holders
representing the requisite  percentage of Voting Rights of Certificates  affected by such default or Event
of Default,  such default or Event of Default  shall cease to exist and shall be deemed to have been cured
and  remedied  for every  purpose  hereunder.  No such  waiver  shall  extend to any  subsequent  or other
default or Event of  Default or impair any right  consequent  thereon  except to the extent  expressly  so
waived.

                                                ARTICLE IX

                                          CONCERNING THE TRUSTEE

SECTION 9.01.     Duties of Trustee.

                  The  Trustee,  prior to the  occurrence  of an Event of Default  and after the curing or
waiver of all Events of  Default  that may have  occurred,  undertakes  with  respect to the Trust Fund to
perform  such  duties and only such duties as are  specifically  set forth in this  Agreement.  In case an
Event of Default of which a Responsible  Officer of the Trustee  shall have actual  knowledge has occurred
and  remains  uncured,  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  person  would
exercise or use under the  circumstances  in the conduct of such  person's  own  affairs.  Any  permissive
right of the Trustee set forth in this Agreement shall not be construed as a duty.

                  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 shall examine them to determine  whether they
conform to the  requirements of this Agreement.  The Trustee shall have no duty to recompute,  recalculate
or verify the accuracy of any resolution,  certificate,  statement,  opinion,  report,  document, order or
other  instrument  so  furnished  to the Trustee.  If any such  instrument  is found not to conform in any
material  respect to the requirements of this Agreement,  the Trustee shall notify the  Certificateholders
of such instrument in the event that the Trustee,  after so requesting,  does not receive a satisfactorily
corrected instrument.

                  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,  its
negligent  failure to perform its obligations in compliance  with this  Agreement,  or any liability which
would be imposed by reason of its willful misfeasance or bad faith; provided, however, that:

(a)      prior to the  occurrence  of an Event of Default of which a  Responsible  Officer of the  Trustee
shall  have  actual  knowledge,  and after  the  curing or of all such  Events  of  Default  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 personally  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 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  which  it
reasonably  believed in good faith to be genuine and to have been duly executed by the proper  authorities
respecting any matters arising hereunder;

(b)      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 the  Trustee  was  negligent  in
ascertaining or investigating the pertinent facts;

(c)      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  this  Agreement  at the  direction  of the
Holders of  Certificates  evidencing  greater than 50% of the Voting  Rights  allocated  to each  Class of
Certificates  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;

(d)      no  provision  of this  Agreement  shall  require  the Trustee 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; and

(e)      the Trustee shall have no  responsibility  for any act or omission of the Trust  Administrator or
a Custodian,  it being understood and agreed that the Trustee,  Trust  Administrator and any Custodian are
independent contractors and not agents, partners or joint venturers.

                  The  Trustee  shall not be deemed to have  knowledge  of any Event of  Default  or event
which,  with notice or lapse of time,  or both,  would  become an Event of Default,  unless a  Responsible
Officer of the Trustee  shall have received  written  notice  thereof from a Servicer,  the Depositor or a
Certificateholder,  or a Responsible Officer of the Trustee has actual notice thereof,  and in the absence
of such notice no provision  hereof  requiring the taking of any action or the assumption of any duties or
responsibility  by the Trustee  following  the  occurrence  of any Event of Default or event  which,  with
notice or lapse of time or both, would become an Event of Default, shall be effective as to the Trustee.

                  The Trustee shall have no duty hereunder with respect to any complaint,  claim,  demand,
notice or other  document it may receive or which may be alleged to have been  delivered to or served upon
it by the parties as a consequence of the assignment of any Mortgage Loan  hereunder;  provided,  however,
that the Trustee shall use its best efforts to remit to the Master  Servicer or the related  Servicer upon
receipt of any such  complaint,  claim,  demand,  notice or other  document  (i) which is delivered to the
Corporate  Trust Office of the Trustee,  (ii) of which a  Responsible  Officer has actual  knowledge,  and
(iii) which  contains  information  sufficient to permit the Trustee to make a determination that the real
property to which such document relates is a Mortgaged Property.

SECTION 9.02.     Certain Matters Affecting the Trustee.

(a)      Except as otherwise provided in Section 9.01:

(i)      the  Trustee  may  request  and rely upon and shall be  protected  in acting or  refraining  from
         acting upon any resolution,  Officer's Certificate,  certificate of auditors,  Servicing Officers
         or any other certificate,  statement,  instrument,  opinion,  report, notice,  request,  consent,
         order,  appraisal,  bond or other paper or document 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,  financial  advisors or accountants  and any advice of such
         Persons 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 with such advice or Opinion of Counsel;

(iii)    the Trustee  shall be under no  obligation  to exercise any of the trusts or powers  vested in it
         by this  Agreement or 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;  nothing  contained herein shall,  however,  relieve the Trustee of
         the  obligation,  upon the  occurrence of an Event of Default of which a  Responsible  Officer of
         the Trustee shall have actual  knowledge  (which has not been cured or waived),  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  person would  exercise or use under the  circumstances  in
         the conduct of such person's own affairs;

(iv)     the Trustee  shall not be personally  liable for any action  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  hereunder and after the curing or waiver of all
         Events  of  Default  that  may  have  occurred,  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 so to do by Holders of  Certificates  evidencing  greater
         than 50% of the Voting Rights allocated to each Class of  Certificates;  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;  the  reasonable  expense of every such  investigation
         shall be paid (A) by the Master  Servicer  or by the  applicable  Servicer in the event that such
         investigation  relates  to an  Event of  Default  by the  Master  Servicer  or by such  Servicer,
         respectively,  if an Event of Default  by the  Master  Servicer  or by such  Servicer  shall have
         occurred  and  is  continuing,  and  (B)  otherwise  by  the  Certificateholders  requesting  the
         investigation;

(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 and the Trustee  shall not be  responsible
         for any  misconduct or negligence  on the part of any such agent or attorney  appointed  with due
         care;

(vii)    the  Trustee  shall not be  required  to expend its own funds or  otherwise  incur any  financial
         liability in the performance of any of its duties  hereunder if it shall have reasonable  grounds
         for believing  that repayment of such funds or adequate  indemnity  against such liability is not
         assured to it;

(viii)   the  Trustee  shall  not be  liable  for any loss on any  investment  of funds  pursuant  to this
         Agreement; and

(ix)     the right of the Trustee to perform any  discretionary  act  enumerated in this  Agreement  shall
         not be  construed  as a duty,  and the  Trustee  shall  not be  answerable  for  other  than  its
         negligence or willful misconduct in the performance of such act.

(b)      All rights of action under this  Agreement or under any of the  Certificates,  enforceable by the
Trustee,  may be enforced by it without  the  possession  of any of the  Certificates,  or the  production
thereof  at the trial or other  proceeding  relating  thereto,  and any such  suit,  action or  proceeding
instituted  by the  Trustee  shall be  brought  in its name for the  benefit  of all the  Holders  of such
Certificates, subject to the provisions of this Agreement.

SECTION 9.03.     Trustee Not Liable for Certificates or Mortgage Loans.

                  The recitals  contained  herein shall be taken as the statements of the Depositor or the
Master  Servicer or a Servicer,  as the case may be, and the Trustee assumes no  responsibility  for their
correctness.  The Trustee makes no  representations  as to the validity or sufficiency of this  Agreement,
the  Certificates  or of any  Mortgage  Loan or  related  document  or of MERS or the  MERS®  System.  The
Trustee shall not be  accountable  for the use or application  by the  Depositor,  the Seller,  the Master
Servicer or any  Servicers of any funds paid to the  Depositor  or the Master  Servicer or any Servicer in
respect  of the  Mortgage  Loans  or  deposited  in or  withdrawn  from  the  Certificate  Account  by the
Depositor,  the Seller,  the Master  Servicer or the Servicers.  The Trustee shall not be responsible  for
the legality or validity of this  Agreement or the validity,  priority,  perfection or  sufficiency of the
security  for the  Certificates  issued or intended  to be issued  hereunder.  The  Trustee  shall have no
responsibility  for filing any financing or continuation  statement in any public office at any time or to
otherwise  perfect or maintain the perfection of any security  interest or lien granted to it hereunder or
to record this Agreement.

SECTION 9.04.     Trustee May Own Certificates.

                  The Trustee in its  individual or any other  capacity may become the owner or pledgee of
Certificates and may transact business with the other parties hereto and with their  Affiliates,  with the
same rights as it would have if it were not the Trustee.

SECTION 9.05.     Trustee's Fees and Expenses.

                  The Trustee shall be compensated by the Trust  Administrator as separately  agreed.  The
Trustee and any  director,  officer,  employee or agent of the Trustee shall be  indemnified  by DLJMC and
held harmless (up to a maximum of $150,000) against any loss,  liability or expense (including  reasonable
attorney's  fees and  expenses)  (i) incurred  in  connection  with any claim or legal action  relating to
(a) this  Agreement,  (b) the  Certificates,  or  (c) the  performance  of  any of  the  Trustee's  duties
hereunder,  other than any loss, liability or expense incurred by reason of willful misconduct,  bad faith
or negligence in the  performance  of any of the Trustee's  duties  hereunder or incurred by reason of any
action of the Trustee taken at the direction of the  Certificateholders  and (ii) resulting from any error
in any tax or information  return  prepared by the Master  Servicer or a Servicer.  Such  indemnity  shall
survive  the  termination  of this  Agreement  or the  resignation  or removal of the  Trustee  hereunder.
Without  limiting the foregoing,  the Depositor  covenants and agrees,  except as otherwise agreed upon in
writing by the Depositor  and the Trustee,  and except for any such  expense,  disbursement  or advance as
may arise  from the  Trustee's  negligence,  bad faith or  willful  misconduct,  to pay or  reimburse  the
Trustee,  for all  reasonable  expenses,  disbursements  and  advances  incurred or made by the Trustee in
accordance   with  any  of  the  provisions  of  this  Agreement  with  respect  to:  (A)  the  reasonable
compensation  and the expenses and  disbursements  of its counsel not  associated  with the closing of the
issuance  of the  Certificates,  (B)  the  reasonable  compensation,  expenses  and  disbursements  of any
accountant,  engineer or appraiser that is not regularly  employed by the Trustee,  to the extent that the
Trustee  must engage such  persons to perform acts or services  hereunder  and (C) printing and  engraving
expenses in connection with preparing any Definitive  Certificates.  Except as otherwise  provided herein,
the Trustee shall not be entitled to payment or reimbursement  for any routine ongoing  expenses  incurred
by the  Trustee  in the  ordinary  course of its duties as Trustee  hereunder  or for any other  expenses.
Anything in this  Agreement to the contrary  notwithstanding,  in no event shall the Trustee be liable for
special,  indirect or  consequential  loss or damage of any kind whatsoever  (including but not limited to
lost  profits),  even if the  Trustee  has been  advised  of the  likelihood  of such loss or  damage  and
regardless of the form of action.

SECTION 9.06.     Eligibility Requirements for Trustee.
                  The Trustee  hereunder shall at all times be a corporation or association  organized and
doing  business  under the laws of any state or the United States of America,  authorized  under such laws
to exercise  corporate trust powers,  having ratings on its long term debt obligations at the time of such
appointment in at least the third highest  rating  category by both Moody's and S&P (provided that if such
rating is in the third highest  rating  category of S&P, the Trustee  shall also have a short-term  rating
from S&P of A-1) or such lower  ratings  as will not cause  Moody's  or S&P to lower  their  then  current
ratings of the Class A  Certificates  (other  than the  Class 4-X  and  Residual  Certificates),  having a
combined  capital and  surplus of at least  $50,000,000  and  subject to  supervision  or  examination  by
federal or state  authority.  If such corporation or association  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 9.06  the  combined  capital and  surplus of such  corporation  or
association  shall be  deemed to be its  combined  capital  and  surplus  as set forth in its most  recent
report  of  condition  so  published.  In case at any time the  Trustee  shall  cease  to be  eligible  in
accordance with the provisions of this  Section 9.06,  the Trustee shall resign  immediately in the manner
and with the effect specified in Section 9.07 hereof.

SECTION 9.07.     Resignation and Removal of Trustee.

                  The Trustee may at any time resign and be discharged  from the trusts hereby  created by
(a) giving  written notice of resignation to the Depositor,  DLJMC,  the Trust  Administrator,  the Master
Servicer,  the Special  Servicer and the Servicers  and by mailing  notice of  resignation  by first class
mail,  postage  prepaid,  to the  Certificateholders  at  their  addresses  appearing  on the  Certificate
Register,  and to the Rating  Agencies,  not less than 60 days  before the date  specified  in such notice
when,  subject to Section 9.08,  such  resignation is to take effect,  and  (b) acceptance  by a successor
trustee in accordance with Section 9.08 meeting the qualifications set forth in Section 9.06.

                  If at  any  time  the  Trustee  shall  cease  to be  eligible  in  accordance  with  the
provisions  of  Section 9.06  hereof  and shall  fail to  resign  after  written  request  thereto  by the
Depositor,  or if at any time the  Trustee  shall  become  incapable  of  acting,  or shall be  adjudged a
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  breaches  any of  its  obligations  or
representations  hereunder,  then the Depositor may remove the Trustee and appoint a successor  trustee by
written instrument,  in duplicate,  one copy of which instrument shall be delivered to the Trustee and one
copy  to the  successor  trustee.  The  Trustee  may  also  be  removed  at any  time  by the  Holders  of
Certificates  evidencing not less than 50% of the Voting Rights evidenced by the  Certificates.  Notice of
any removal of the Trustee and acceptance of  appointment  by the successor  trustee shall be given to the
Rating Agencies 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  or  receipt of a notice of  removal,  the
resigning Trustee may, at the Trust Fund's expense,  petition any court of competent  jurisdiction for the
appointment of a successor trustee.

                  Any  resignation  or removal of the  Trustee  and  appointment  of a  successor  trustee
pursuant  to any of the  provisions  of this  Section 9.07  shall  become  effective  upon  acceptance  of
appointment by the successor trustee as provided in Section 9.08 hereof.

SECTION 9.08.     Successor Trustee.

                  Any  successor  trustee  appointed as provided in  Section 9.07  hereof  shall  execute,
acknowledge  and deliver to the Depositor and to its  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  Depositor,  upon  receipt of all  amounts due it
hereunder,  and the  predecessor  trustee  shall  execute and deliver such  instruments  and do such other
things as may  reasonably  be  required  for more  fully  and  certainly  vesting  and  confirming  in the
successor trustee all such rights, powers, duties, and obligations.

                  No successor trustee shall accept  appointment as provided in this  Section 9.08  unless
at the time of such  acceptance  such  successor  trustee  shall  be  eligible  under  the  provisions  of
Section 9.06  hereof  and its  acceptance  shall  not  adversely  affect  the then  current  rating of the
Certificates.

                  Upon   acceptance  of   appointment   by  a  successor   trustee  as  provided  in  this
Section 9.08,  the Depositor shall mail notice of the succession of such trustee  hereunder to all Holders
of Certificates at their  addresses as shown in the Certificate  Register.  If the Depositor fails to mail
such notice  within ten days after  acceptance of  appointment  by the  successor  trustee,  the successor
trustee shall cause such notice to be mailed at the expense of the Depositor.

SECTION 9.09.     Merger or Consolidation of Trustee.

                  Any Person  into which the Trustee  may be merged or  converted  or with which it may be
consolidated or any Person  resulting from any merger,  conversion or  consolidation  to which the Trustee
shall be a party, or any Person  succeeding to the business of the Trustee,  shall be the successor of the
Trustee  hereunder,  provided  that such Person shall be eligible  under the  provisions  of  Section 9.06
hereof  without  the  execution  or filing of any paper or further  act on the part of any of the  parties
hereto, anything herein to the contrary notwithstanding.

SECTION 9.10.     Appointment of Co-Trustee or Separate Trustee.

                  Notwithstanding  any other  provisions of this  Agreement,  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  any  Mortgage  Note may at the time be  located,  the Master  Servicer  and the  Trustee  acting
jointly  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 and for the benefit of the applicable  Certificateholders,  such title to the
Trust Fund, or any part thereof,  and, subject to the other provisions of this Section 9.10,  such powers,
duties,  obligations,  rights and trusts as the Master Servicer and the Trustee may consider  necessary or
desirable.  If the Master  Servicer  shall not have joined in such  appointment  within fifteen days after
the  receipt by it of a request to do so, or in the case an Event of Default  shall have  occurred  and be
continuing,  the Trustee  alone shall have the power to make such  appointment.  No co-trustee or separate
trustee  hereunder  shall be  required  to meet the terms of  eligibility  as a  successor  trustee  under
Section 9.06 and no notice to  Certificateholders of the appointment of any co-trustee or separate trustee
shall be required under Section 9.08.

                  Every  separate  trustee  and  co-trustee  shall,  to the extent  permitted  by law,  be
appointed and act subject to the following provisions and conditions:

(a)      all rights,  powers,  duties and  obligations  conferred or imposed upon the Trustee,  except for
any  obligation of the Trustee under this  Agreement to advance funds on behalf of the Master  Servicer or
a  Servicer,  shall be  conferred  or imposed  upon and  exercised  or  performed  by the Trustee and such
separate  trustee or co-trustee  jointly (it being  understood that such separate trustee or co-trustee is
not  authorized  to act  separately  without the Trustee  joining in such act),  except to the extent that
under any law of any  jurisdiction  in which any particular act or acts are to be performed by the Trustee
(whether as Trustee  hereunder or as successor to the Master  Servicer or a Servicer),  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 singly by such separate trustee or co-trustee,  but solely
at the direction of the Trustee;

(b)      no trustee  hereunder  shall be held  personally  liable by reason of any act or  omission of any
other trustee hereunder; and

(c)      the Master  Servicer and the Trustee acting jointly may at any time accept the  resignation of or
remove any separate trustee or co-trustee.

                  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 IX. 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  and a copy  thereof  given to the  Master  Servicer  or the
Servicers and the Depositor.

                  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.  The Trust  Administrator
shall not be  responsible  for all  action or  inaction  of any  separate  trustee or  co-trustee.  If any
separate  trustee or co-trustee shall die, become  incapable of acting,  resign or be removed,  all of its
estates,  properties,  rights,  remedies and trusts shall vest in and be exercised by the Trustee,  to the
extent permitted by law, without the appointment of a new or successor trustee.

SECTION 9.11.     Office of the Trustee.

                  The  office of the  Trustee  for  purposes  of receipt  of  notices  and  demands is the
Corporate Trust Office.

                                                ARTICLE X

                                    CONCERNING THE TRUST ADMINISTRATOR

SECTION 10.01.    Duties of Trust Administrator.

                  The Trust  Administrator,  prior to the  occurrence  of an Event of  Default  of which a
Responsible  Officer  of the Trust  Administrator  shall  have  actual  knowledge  and after the curing or
waiver of all Events of  Default  that may have  occurred,  undertakes  with  respect to the Trust Fund to
perform  such  duties and only such duties as are  specifically  set forth in this  Agreement.  In case an
Event of Default of which a Responsible  Officer of the Trust  Administrator  shall have actual  knowledge
has occurred and remains  uncured,  the Trust  Administrator  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  person  would  exercise  or use under the  circumstances  in the  conduct  of such  person's  own
affairs.  Any  permissive  right of the  Trust  Administrator  set  forth in this  Agreement  shall not be
construed as a duty.

                  The Trust  Administrator,  upon receipt of all  resolutions,  certificates,  statements,
opinions,  reports,  documents,  orders or other instruments furnished to the Trust Administrator that are
specifically  required to be furnished  pursuant to any provision of this Agreement  shall examine them to
determine  whether they conform to the  requirements  of this  Agreement.  The Trust  Administrator  shall
have no duty to recompute, recalculate or verify the accuracy of any resolution,  certificate,  statement,
opinion,  report,  document,  order or other  instrument so furnished to the Trust  Administrator.  If any
such  instrument is found not to conform in any material  respect to the  requirements  of this Agreement,
the Trust  Administrator  shall notify the  Certificateholders  of such  instrument  in the event that the
Trust Administrator, after so requesting, does not receive a satisfactorily corrected instrument.

                  No provision  of this  Agreement  shall be construed to relieve the Trust  Administrator
from liability for its own negligent action,  its own negligent failure to act or its own misconduct,  its
negligent  failure to perform its obligations in compliance  with this  Agreement,  or any liability which
would be imposed by reason of its willful misfeasance or bad faith; provided, however, that:

(a)      prior to the  occurrence  of an Event of  Default  of which a  Responsible  Officer  of the Trust
Administrator  shall have actual  knowledge,  and after the curing or of all such  Events of Default  that
may have occurred,  the duties and obligations of the Trust  Administrator  shall be determined  solely by
the express provisions of this Agreement,  the Trust  Administrator  shall not be personally 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 Trust  Administrator and
the Trust  Administrator  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 Trust  Administrator
and  conforming to the  requirements  of this Agreement  which it reasonably  believed in good faith to be
genuine  and to have  been  duly  executed  by the  proper  authorities  respecting  any  matters  arising
hereunder;

(b)      the Trust  Administrator  shall not be  personally  liable for an error of judgment  made in good
faith by a  Responsible  Officer or  Responsible  Officers  of the Trust  Administrator,  unless the Trust
Administrator was negligent in ascertaining or investigating the pertinent facts;

(c)      the Trust  Administrator  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  this  Agreement  or at the
direction of the Holders of  Certificates  evidencing  greater than 50% of the Voting Rights  allocated to
each Class of  Certificates  relating to the time,  method and place of conducting  any proceeding for any
remedy  available to the Trust  Administrator,  or exercising any trust or power  conferred upon the Trust
Administrator, under this Agreement; and

(d)      no provision of this Agreement  shall require the Trust  Administrator  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.

                  The  Trust  Administrator  shall  have no duty (A) to see to any  recording,  filing  or
depositing  of  this  Agreement  or any  agreement  referred  to  herein  or any  financing  statement  or
continuation  statement  evidencing  a  security  interest,  or to  see  to the  maintenance  of any  such
recording,  filing or depositing or to any  rerecording,  refiling or redepositing of any thereof,  (B) to
see to  any  insurance,  or (C) to see to the  payment  or  discharge  of any  tax,  assessment  or  other
governmental  charge or any lien or  encumbrance  of any kind owing with  respect  to,  assessed or levied
against, any part of the Trust Fund other than from funds available in the Certificate Account.

                  Except with  respect to an Event of Default  described  in clause  (a) of  Section 8.01,
the Trust  Administrator  shall not be deemed to have  knowledge  of any Event of Default or event  which,
with notice or lapse of time, or both, would become an Event of Default,  unless a Responsible  Officer of
the Trust  Administrator  shall  have  received  written  notice  thereof  from the Master  Servicer  or a
Servicer, the Depositor,  or a Certificateholder,  or a Responsible Officer of the Trust Administrator has
actual notice thereof,  and in the absence of such notice no provision  hereof requiring the taking of any
action  or the  assumption  of any  duties or  responsibility  by the Trust  Administrator  following  the
occurrence of any Event of Default or event which,  with notice or lapse of time or both,  would become an
Event of Default, shall be effective as to the Trust Administrator.

                  The Trust  Administrator  shall have no duty  hereunder  with respect to any  complaint,
claim,  demand,  notice or other document it may receive or which may be alleged to have been delivered to
or served upon it by the parties as a  consequence  of the  assignment  of any  Mortgage  Loan  hereunder;
provided,  however,  that the  Trust  Administrator  shall  use its best  efforts  to remit to the  Master
Servicer or the Servicer  upon receipt of any such  complaint,  claim,  demand,  notice or other  document
(i) which  is  delivered  to the  Corporate  Trust  Office of the  Trust  Administrator,  (ii) of  which a
Responsible Officer has actual knowledge,  and (iii) which contains  information  sufficient to permit the
Trust  Administrator  to make a determination  that the real property to which such document  relates is a
Mortgaged Property.

SECTION 10.02.    Certain Matters Affecting the Trust Administrator.

(a)      Except as otherwise provided in Section 10.01:

(i)      the  Trust  Administrator  may  request  and  rely  upon and  shall be  protected  in  acting  or
         refraining  from acting upon any  resolution,  Officer's  Certificate,  certificate  of auditors,
         Servicing Officers or any other certificate,  statement,  instrument,  opinion,  report,  notice,
         request,  consent,  order,  appraisal,  bond or other  paper  or  document  believed  by it to be
         genuine and to have been signed or presented by the proper party or parties;

(ii)     the Trust  Administrator  may consult with counsel,  financial  advisors or  accountants  and any
         advice of such  Persons  or  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 with such advice or opinion of counsel;

(iii)    the Trust  Administrator  shall be under no  obligation  to exercise  any of the trusts or powers
         vested in it by this  Agreement or 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
         Trust  Administrator   reasonable   security  or  indemnity  against  the  costs,   expenses  and
         liabilities which may be incurred therein or thereby;  nothing  contained herein shall,  however,
         relieve the Trust  Administrator  of the  obligation,  upon the occurrence of an Event of Default
         of which a Responsible  Officer of the Trust  Administrator  shall have actual  knowledge  (which
         has not been cured or  waived),  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  person
         would exercise or use under the circumstances in the conduct of such person's own affairs;

(iv)     the Trust  Administrator  shall not be  personally  liable  for any  action  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  hereunder and after the curing or waiver of all
         Events of Default  that may have  occurred,  the Trust  Administrator  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 so to do by Holders of  Certificates  evidencing  greater
         than 50% of the Voting Rights allocated to each Class of  Certificates;  provided,  however, that
         if the payment  within a reasonable  time to the Trust  Administrator  of the costs,  expenses or
         liabilities  likely to be incurred by it in the making of such  investigation  is, in the opinion
         of the Trust  Administrator,  not reasonably  assured to the Trust  Administrator by the security
         afforded to it by the terms of this Agreement,  the Trust  Administrator  may require  reasonable
         indemnity  against  such  expense or  liability  as a condition  to taking any such  action;  the
         reasonable  expense of every such  investigation  shall be paid (A) by the Master  Servicer or by
         the applicable  Servicer in the event that such  investigation  relates to an Event of Default by
         the  Master  Servicer  or by such  Servicer,  respectively,  if an Event of Default by the Master
         Servicer or such  Servicer  shall have  occurred  and is  continuing,  and (B)  otherwise  by the
         Certificateholders requesting the investigation;

(vi)     the Trust  Administrator  may execute any of the trusts or powers hereunder or perform any duties
         hereunder  either  directly  or by or through  agents or  attorneys  and the Trust  Administrator
         shall not be  responsible  for any  misconduct  or  negligence  on the part of any such  agent or
         attorney appointed with due care;

(vii)    the Trust  Administrator  shall not be  required to expend its own funds or  otherwise  incur any
         financial  liability  in the  performance  of  any  of its  duties  hereunder  if it  shall  have
         reasonable  grounds for  believing  that  repayment of such funds or adequate  indemnity  against
         such liability is not assured to it;

(viii)   the Trust  Administrator  shall not be liable for any loss on any investment of funds pursuant to
         this Agreement except as provided in Section 3.05(e);

(ix)     the  right of the Trust  Administrator  to  perform  any  discretionary  act  enumerated  in this
         Agreement shall not be construed as a duty, and the Trust  Administrator  shall not be answerable
         for other than its negligence or willful misconduct in the performance of such act; and

(x)      The Trust  Administrator  shall not be  required  to give any bond or  surety in  respect  of the
         execution of the Trust Fund created hereby or the powers granted hereunder.

(b)      All rights of action under this  Agreement or under any of the  Certificates,  enforceable by the
Trust  Administrator,  may be enforced by it without the  possession  of any of the  Certificates,  or the
production  thereof  at the trial or other  proceeding  relating  thereto,  and any such  suit,  action or
proceeding  instituted by the Trust  Administrator shall be brought in its name for the benefit of all the
Holders of such Certificates, subject to the provisions of this Agreement.

SECTION 10.03.    Trust Administrator Not Liable for Certificates or Mortgage Loans.

                  The recitals  contained  herein shall be taken as the statements of the Depositor or the
Master Servicer or a Servicer,  as the case may be, and the Trust Administrator  assumes no responsibility
for  their  correctness.  The  Trust  Administrator  makes  no  representations  as  to  the  validity  or
sufficiency of this Agreement,  the  Certificates or of any Mortgage Loan or related  document.  The Trust
Administrator  shall not be  accountable  for the use or application  by the  Depositor,  the Seller,  the
Master  Servicer  or the  Servicers  of any funds  paid to the  Depositor  or the Master  Servicer  or any
Servicer in respect of the Mortgage  Loans or deposited in or withdrawn  from the  Certificate  Account by
the Depositor,  the Seller,  the Master Servicer or the Servicers.  The Trust  Administrator  shall not be
responsible  for the  legality or validity of this  Agreement or the  validity,  priority,  perfection  or
sufficiency  of the security for the  Certificates  issued or intended to be issued  hereunder.  The Trust
Administrator  shall have no  responsibility  for filing any  financing or  continuation  statement in any
public office at any time or to otherwise  perfect or maintain the  perfection  for any security  interest
or lien granted to it hereunder or to record this Agreement.

SECTION 10.04.    Trust Administrator May Own Certificates.

                  The Trust  Administrator  in its  individual or any other  capacity may become the owner
or pledgee of Certificates with the same rights as it would have if it were not the Trust Administrator.

SECTION 10.05.    Trust Administrator's Fees and Expenses.

                  As compensation for its services  hereunder,  the Trust  Administrator shall be entitled
to the investment  income or other benefit  derived from balances in the Certificate  Account  pursuant to
Section 3.05(e) (the  "Trust  Administrator  Fee").  The Trust  Administrator  and any director,  officer,
employee or agent of the Trust  Administrator  shall be indemnified by DLJMC (or if DLJMC shall fail to do
so, by the  Trust)  and held  harmless  against  any loss,  liability  or  expense  (including  reasonable
attorney's  fees and  expenses)  (i) incurred  in  connection  with any claim or legal action  relating to
(a) this Agreement,  (b) the Certificates,  (c) the Custodial Agreement,  or (d) the performance of any of
the  Trust  Administrator's  duties  hereunder  or under the  Custodial  Agreement,  other  than any loss,
liability  or  expense  incurred  by  reason  of  willful  misfeasance,  bad  faith or  negligence  in the
performance of any of the Trust  Administrator's  duties  hereunder or incurred by reason of any action of
the Trust  Administrator  taken at the direction of the  Certificateholders  and  (ii) resulting  from any
error in any tax or information return prepared by the Master Servicer or a Servicer;  provided,  however,
that the sum of  (x) such  indemnity  amounts  payable  by DLJMC or the Trust to the  Trust  Administrator
pursuant to this  Section 10.05  and (y) the indemnity amounts payable by DLJMC or the Trust to the Master
Servicer pursuant to  Section 3.14(c),  shall not exceed $200,000 per year;  provided,  further,  that any
amounts not payable by DLJMC or the Trust to the Trust  Administrator  due to the preceding  proviso shall
be payable  by DLJMC (or if DLJMC  fails to do so, by the Trust) in any  succeeding  year,  subject to the
aggregate  $200,000 per annum limitation  imposed by the preceding  proviso.  Such indemnity shall survive
the  termination of this Agreement or the  resignation  or removal of the Trust  Administrator  hereunder.
Without limiting the foregoing,  DLJMC (or if DLJMC fails to do so, the Trust) shall,  except as otherwise
agreed  upon in  writing  by  DLJMC  and the  Trust  Administrator,  and  except  for  any  such  expense,
disbursement  or  advance  as may arise from the Trust  Administrator's  negligence,  bad faith or willful
misconduct,  pay or reimburse the Trust  Administrator  (up to a maximum of $150,000),  for all reasonable
expenses,  disbursements and advances  incurred or made by the Trust  Administrator in accordance with any
of the  provisions of this Agreement  with respect to: (A) the  reasonable  compensation  and the expenses
and  disbursements  of its counsel not  associated  with the closing of the issuance of the  Certificates,
(B) the reasonable  compensation,  expenses and  disbursements  of any  accountant,  engineer or appraiser
that is not  regularly  employed by the Trust  Administrator,  to the extent that the Trust  Administrator
must engage such persons to perform acts or services  hereunder  and (C) printing and  engraving  expenses
in connection  with preparing any  Definitive  Certificates.  In addition,  DLJMC (or if DLJMC fails to do
so, the Trust) shall pay or reimburse  the Trust  Administrator  for  recertification  fees required to be
paid by the  Trust  Administrator  pursuant  to the  Custodial  Agreement.  Except as  otherwise  provided
herein,  the Trust  Administrator  shall not be  entitled  to payment  or  reimbursement  for any  routine
ongoing  expenses  incurred  by the Trust  Administrator  in the  ordinary  course of its  duties as Trust
Administrator,  Registrar,  Tax Matters  Person or Paying Agent  hereunder.  Anything in this Agreement to
the contrary  notwithstanding,  in no event shall the Trust Administrator be liable for special,  indirect
or consequential loss or damage of any kind whatsoever  (including but not limited to lost profits),  even
if the Trust  Administrator  has been advised of the  likelihood of such loss or damage and  regardless of
the form of action.

SECTION 10.06.    Eligibility Requirements for Trust Administrator.

                  The  Trust  Administrator  hereunder  shall  at all  times  be  (a) an  institution  the
deposits of which are fully insured by the FDIC and (b) a  corporation  or banking  association  organized
and doing  business  under the laws of any state or the United  States of America,  authorized  under such
laws to exercise  corporate trust powers,  having a combined  capital and surplus of at least  $50,000,000
and subject to  supervision or  examination  by federal or state  authority and (c) with  respect to every
successor Trust  Administrator  hereunder an institution the long-term unsecured debt obligations of which
are rated at least  Baa3 or better by Moody's  and BBB or better by S&P  unless  the  failure of the Trust
Administrator's  long-term  unsecured  debt  obligations  to have such  ratings  would  not  result in the
lowering  of the  ratings  originally  assigned  to any  Class of  Certificates.  If such  corporation  or
banking  association  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 10.06  the combined capital and surplus of such  corporation or association  shall be deemed to be
its combined  capital and surplus as set forth in its most recent  report of condition  so  published.  In
case at any time the Trust  Administrator  shall cease to be eligible in accordance with the provisions of
this  Section 10.06,  the Trust  Administrator  shall resign immediately in the manner and with the effect
specified in Section 10.07 hereof.

SECTION 10.07.    Resignation and Removal of Trust Administrator.

                  The  Trust  Administrator  may at any time  resign  and be  discharged  from the  trusts
hereby created by (a) giving  written notice of  resignation  to the Depositor,  the Seller,  the Trustee,
the Master  Servicer,  the Special  Servicer and the Servicers  and by mailing  notice of  resignation  by
first  class  mail,  postage  prepaid,  to the  Certificateholders  at their  addresses  appearing  on the
Certificate  Register,  and to the Rating  Agencies,  not less than 60 days before the date  specified  in
such notice when,  subject to Section 10.08,  such resignation is to take effect,  and (b) acceptance by a
successor trust  administrator in accordance with  Section 10.08  meeting the  qualifications set forth in
Section 10.06.

                  If at any time the Trust  Administrator  shall cease to be eligible in  accordance  with
the  provisions  of  Section 10.06  hereof and shall fail to resign after written  request  thereto by the
Depositor,  or if at any time the Trust  Administrator  shall  become  incapable  of  acting,  or shall be
adjudged a bankrupt or insolvent,  or a receiver of the Trust  Administrator  or of its property  shall be
appointed,  or any public  officer  shall take  charge or  control  of the Trust  Administrator  or of its
property  or affairs  for the  purpose of  rehabilitation,  conservation  or  liquidation  or if the Trust
Administrator  breaches any of its  obligations  or  representations  hereunder,  then the  Depositor  may
remove the Trust  Administrator  and appoint a successor trust  administrator  by written  instrument,  in
duplicate,  one copy of which  instrument  shall be delivered to the Trust  Administrator  and one copy to
the  successor  trust  administrator.  The  Trust  Administrator  may also be  removed  at any time by the
Trustee or the Holders of  Certificates  evidencing  not less than 50% of the Voting  Rights  evidenced by
the  Certificates.  Notice of any removal of the Trust  Administrator and acceptance of appointment by the
successor trust administrator shall be given to the Rating Agencies by the Depositor.

                  If no  successor  trust  administrator  shall have been so appointed  and have  accepted
appointment  within 30 days  after the  giving of such  notice of  resignation  or  receipt of a notice of
removal,  the  resigning  Trust  Administrator  may, at the Trust  Fund's  expense,  petition any court of
competent jurisdiction for the appointment of a successor trust administrator.

                  Notwithstanding  the  foregoing,  if the Master  Servicer shall for any reason no longer
be Master  Servicer  hereunder,  at  DLJMC's  request,  the Trust  Administrator  shall  resign,  upon the
selection and  appointment of a successor  trust  administrator  meeting the  qualifications  set forth in
Section 10.06.

                  Any  resignation or removal of the Trust  Administrator  and  appointment of a successor
trust  administrator  pursuant to any of the provisions of this Section 10.07  shall become effective upon
acceptance of appointment by the successor trust administrator as provided in Section 10.08 hereof.

SECTION 10.08.    Successor Trust Administrator.

                  Any successor trust  administrator  appointed as provided in Section 10.07  hereof shall
execute,  acknowledge  and  deliver  to the  Depositor  and  to its  predecessor  trust  administrator  an
instrument  accepting  such  appointment  hereunder  and  thereupon  the  resignation  or  removal  of the
predecessor trust  administrator  shall become effective and such successor trust  administrator,  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  Trust
Administrator  herein.  The Depositor,  upon receipt of all amounts due it hereunder,  and the predecessor
trust  administrator  shall  execute  and  deliver  such  instruments  and do  such  other  things  as may
reasonably  be  required  for more fully and  certainly  vesting and  confirming  in the  successor  trust
administrator all such rights, powers, duties, and obligations.

                  No  successor  trust   administrator  shall  accept  appointment  as  provided  in  this
Section 10.08  unless at the time of such acceptance such successor trust  administrator shall be eligible
under the  provisions of  Section 10.06  hereof and its  acceptance  shall not  adversely  affect the then
current rating of the Certificates.

                  Upon  acceptance of appointment by a successor trust  administrator  as provided in this
Section 10.08,  the Depositor  shall mail notice of the succession of such trust  administrator  hereunder
to all  Holders  of  Certificates  at  their  addresses  as  shown  in the  Certificate  Register.  If the
Depositor  fails to mail such notice  within ten days after  acceptance  of  appointment  by the successor
trust  administrator,  the  successor  trust  administrator  shall  cause such  notice to be mailed at the
expense of the Depositor.

SECTION 10.09.    Merger or Consolidation of Trust Administrator.

                  Any Person into which the Trust  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 the
Trust  Administrator  shall  be  a  party,  or  any  Person  succeeding  to  the  business  of  the  Trust
Administrator,  shall be the  successor of the Trust  Administrator  hereunder,  provided that such Person
shall be eligible  under the  provisions of  Section 10.06  hereof  without the execution or filing of any
paper  or  further  act on  the  part  of any of the  parties  hereto,  anything  herein  to the  contrary
notwithstanding.

SECTION 10.10.    Appointment of Co-Trust Administrator or Separate Trust Administrator.

                  Notwithstanding  any other  provisions of this  Agreement,  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 any Mortgage  Note may at the time be located,  the Master  Servicer and the Trust  Administrator
acting  jointly shall have the power and shall execute and deliver all  instruments to appoint one or more
Persons approved by the Trust  Administrator to act as co-trust  administrator or co-trust  administrators
jointly with the Trust  Administrator,  or separate trust administrator or separate trust  administrators,
of all or any part of the Trust  Fund,  and to vest in such Person or Persons,  in such  capacity  and for
the  benefit of the  applicable  Certificateholders,  such title to the Trust Fund,  or any part  thereof,
and, subject to the other provisions of this Section 10.10,  such powers, duties, obligations,  rights and
trusts as the Master  Servicer and the Trust  Administrator  may consider  necessary or desirable.  If the
Master Servicer shall not have joined in such  appointment  within fifteen days after the receipt by it of
a request to do so, or in the case an Event of Default  shall have occurred and be  continuing,  the Trust
Administrator  alone  shall  have  the  power to make  such  appointment.  No  co-trust  administrator  or
separate trust  administrator  hereunder shall be required to meet the terms of eligibility as a successor
trust  administrator  under  Section 10.06 and no notice to  Certificateholders  of the appointment of any
co-trust administrator or separate trust administrator shall be required under Section 10.08.

                  Every separate  trust  administrator  and co-trust  administrator  shall,  to the extent
permitted by law, be appointed and act subject to the following provisions and conditions:

(a)      all rights,  powers,  duties and obligations  conferred or imposed upon the Trust  Administrator,
except for any  obligation of the Trust  Administrator  under this Agreement to advance funds on behalf of
the Master  Servicer or the  Servicer,  shall be conferred  or imposed upon and  exercised or performed by
the Trust  Administrator  and such separate  trust  administrator  or co-trust  administrator  jointly (it
being  understood that such separate trust  administrator  or co-trust  administrator is not authorized to
act separately without the Trust  Administrator  joining in such act), except to the extent that under any
law  of any  jurisdiction  in  which  any  particular  act  or  acts  are  to be  performed  by the  Trust
Administrator  (whether as Trust  Administrator  hereunder or as  successor to the Master  Servicer or the
Servicer),  the Trust  Administrator  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  singly by such
separate  trust  administrator  or  co-trust  administrator,  but  solely  at the  direction  of the Trust
Administrator;

(b)      no trust  administrator  hereunder  shall  be held  personally  liable  by  reason  of any act or
omission of any other trust administrator hereunder; and

(c)      the  Master  Servicer  and the Trust  Administrator  acting  jointly  may at any time  accept the
resignation of or remove any separate trust administrator or co-trust administrator.

                  Any notice,  request or other writing given to the Trust  Administrator  shall be deemed
to have been given to each of the then  separate  trust  administrators  and co-trust  administrators,  as
effectively as if given to each of them.  Every  instrument  appointing  any separate trust  administrator
or co-trust  administrator  shall  refer to this  Agreement  and the  conditions  of this  Article X. Each
separate trust  administrator  and co-trust  administrator,  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 Trust Administrator 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 Trust  Administrator.  Every such  instrument
shall be filed  with the Trust  Administrator  and a copy  thereof  given to the  Master  Servicer  or the
Servicers and the Depositor.

                  Any  separate  trust   administrator  or  co-trust   administrator  may,  at  any  time,
constitute the Trust Administrator,  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.  The Trust  Administrator  shall not be  responsible  for any action or  inaction  of any
separate Trust  Administrator or Co-Trust  Administrator.  If any separate trust administrator or co-trust
administrator  shall  die,  become  incapable  of  acting,  resign  or be  removed,  all of  its  estates,
properties,  rights,  remedies and trusts shall vest in and be  exercised by the Trust  Administrator,  to
the extent permitted by law, without the appointment of a new or successor trust administrator.

SECTION 10.11.    Office of the Trust Administrator.

                  The office of the Trust  Administrator  for  purposes  of receipt of notices and demands
is the Corporate Trust Office.

SECTION 10.12.    Tax Return.

                  The  Master  Servicer  and  each  Servicer,   upon  request,  shall  furnish  the  Trust
Administrator  with all such  information  related to the Mortgage  Loans in the  possession of the Master
Servicer or such Servicer as may be reasonably  required in connection  with the  preparation by the Trust
Administrator  of all tax and  information  returns of the Trust Fund, and the Trust  Administrator  shall
sign such returns. The Master Servicer and each Servicer,  severally and not jointly,  shall indemnify the
Trust  Administrator  for all reasonable  costs,  including legal fees and expenses,  related to errors in
such tax  returns  due to errors  only in such  information  provided  by the Master  Servicer  or by such
Servicer.

SECTION 10.13.    Determination of Certificate Index.

                  On each Interest  Determination  Date,  the Trust  Administrator  shall  determine  each
Certificate  Index for the Accrual Period and inform the Master  Servicer of such rate and such rate shall
be final and binding, absent a manifest error of the Trust Administrator.

                                                ARTICLE XI

         Group Balance for Loan Group 4 as of the Cut-off Date.

(b)      the later of  (i) twelve  months after the maturity of the last  Mortgage  Loan  remaining in the
Trust Fund,  (ii) the  liquidation  (or any  advance  with  respect  thereto)  of the last  Mortgage  Loan
remaining  in the Trust  Fund and the  disposition  of all  REO Property  and  (iii) the  distribution  to
Certificateholders of all amounts required to be distributed to them pursuant to this Agreement; or

(c)      (i) with  respect  to  Loan  Group 1,  Loan  Group 2  and  Loan  Group 3,  the  purchase  by  the
         Terminating  Auction  Purchaser  of all  Mortgage  Loans in such  Loan  Groups  and all  property
         acquired  in respect of any  remaining  Mortgage  Loan in such Loan Group  (with  respect to Loan
         Group 1, Loan Group 2 and Loan Group 3, the "Trust Collateral") as described below; or

                           (ii)     with respect to Loan Group 4,  the purchase by the Terminating Auction
         Purchaser  of all  Mortgage  Loans in Loan  Group 4 and all  property  acquired in respect of any
         remaining  Mortgage  Loan  in  such  Loan  Group  (with  respect  to  Loan  Group 4,  the  "Trust
         Collateral") as described below.

                  In no event  shall the trust  created  hereby  continue  beyond  the  earlier of (i) the
expiration  of 21 years from the death of the last survivor of the  descendants  of Mr. Joseph P. Kennedy,
former  Ambassador  of the  United  States  to Great  Britain,  living  on the date of  execution  of this
Agreement or (ii) the  Distribution  Date following the third  anniversary of the scheduled  maturity date
of the Mortgage Loan having the latest scheduled maturity date as of the Cut-off Date.

                  The "Mortgage Loan Purchase Price" for any such Optional  Termination  shall be equal to
the  greater of (a) the  sum of  (i) 100% of the Stated  Principal  Balance of each  Mortgage  Loan in the
applicable  Loan  Group(s) (other  than in respect  of  REO Property)  plus  accrued  and unpaid  interest
thereon from the date to which such  interest was paid or advanced at the  applicable  Mortgage  Rate,  to
but not  including  the Due Date in the month of the final  Distribution  Date (or the Net  Mortgage  Rate
with respect to any related  Mortgage  Loan  currently  serviced by the entity  exercising  such  Optional
Termination)  and (ii) with  respect to any  REO Property,  the lesser of (x) the  appraised  value of any
REO Property  as  determined  by the higher of two  appraisals  completed  by two  independent  appraisers
selected by the  Depositor at the expense of the Depositor and (y) the  Stated  Principal  Balance of each
related  Mortgage  Loan related to any  REO Property,  in each case and (iii) any  remaining  unreimbursed
Advances,  Servicing  Advances and unpaid Servicing Fees (other than any remaining  unreimbursed  Advances
and  Servicing  Advances  and unpaid  Servicing  Fees,  if any, due to the  Terminating  Entity) and other
amounts payable to the Trustee and Trust  Administrator  (the sum of (i),  (ii) and  (iii),  collectively,
the "Par Value") and (b) the  Fair Market  Value of all of the  property of the Trust  related to the Loan
Group(s) subject to such Optional Termination.

                  The "Fair  Market  Value"  shall be the fair market  value of all of the property of the
Trust  related to the Loan  Group(s)  subject to an  Optional  Termination,  as agreed  upon  between  the
Terminating Entity and a majority of the holders of the Class AR-L Certificates;  provided,  however, that
if the Terminating  Entity and a majority of the holders of the Class AR-L  Certificates do not agree upon
the fair market value of such property of the Trust,  the  Terminating  Entity,  or an agent  appointed by
the  Terminating  Entity,  shall solicit bids for such  property of the Trust until it has received  three
bids,  and  the  Fair  Market  Value  shall  be  equal  to the  highest  of such  three  bids.  The  Trust
Administrator  shall give  notice to the Rating  Agencies  of any  election  to  purchase  Mortgage  Loans
pursuant to this Section 11.01 and of the applicable Optional Termination Date.

(d)      On any  Distribution  Date on or after the date on which the aggregate  Principal  Balance of the
Mortgage  Loans  in  Loan  Group 1,  Loan  Group 2  and  Loan  Group 3  is less  than 5% of the  Aggregate
Groups 1-3  Collateral  Balance  as  of  the  Cut-off  Date  (a "Terminating  Auction  Date"),  the  Trust
Administrator  shall solicit bids for the related Trust Collateral from at least three  institutions  that
are regular  purchasers  and/or  sellers in the  secondary  market of  residential  whole  mortgage  loans
similar to the Mortgage  Loans.  If the Trust  Administrator  receives at least three bids for the related
Trust  Collateral,  and  one of  such  bids  is  equal  to or  greater  than  the  Par  Value,  the  Trust
Administrator  shall sell the related  Trust  Collateral  to the highest  bidder (a  "Terminating  Auction
Purchaser")  at the price  offered by the  Terminating  Auction  Purchaser (a "Mortgage  Loan  Terminating
Auction Price");  provided,  however,  that the Seller shall be disqualified from bidding and may not be a
Terminating  Auction  Purchaser.  If the Trust  Administrator  receives  less than three bids, or does not
receive any bid that is equal to or greater than the Par Value,  the Trust  Administrator  shall,  on each
six-month  anniversary of the initial  Terminating Auction Date, repeat these auction procedures until the
Trust  Administrator  receives a bid that is equal to or greater  than the Par Value,  and upon receipt of
such bid shall sell the related Trust  Collateral to the  Terminating  Auction  Purchaser at that Mortgage
Loan Terminating Auction Price;  provided,  however, that the Trust Administrator shall not be required to
repeat these auction  procedures on any  Distribution  Date for any six-month  anniversary  of the initial
Terminating  Auction Date unless the Trust  Administrator  reasonably  believes that there is a reasonable
likelihood  of receiving a bid in excess of the Par Value.  The Trust  Administrator  shall give notice to
the Rating  Agencies and each Servicer that is servicing any of the related  Mortgage Loans of the sale of
the related Trust  Collateral  pursuant to this  Section 11.01  (a "Terminating  Auction Sale") and of the
Terminating  Auction  Date.  Notwithstanding  anything to the contrary  herein,  the  Terminating  Auction
Purchaser shall not be the Depositor, the Seller or any of their respective Affiliates.

(e)      On any  Distribution  Date on or after the date on which the aggregate  Principal  Balance of the
Mortgage  Loans in Loan Group 4 is less than 5% of the  Aggregate  Loan Group  Balance for Loan Group 4 as
of the Cut-off Date (a "Terminating  Auction Date"),  the Trust  Administrator  shall solicit bids for the
related Trust Collateral from at least three  institutions  that are regular  purchasers and/or sellers in
the  secondary  market of  residential  whole  mortgage  loans  similar to the Mortgage  Loans;  provided,
however,  that the Trust Administrator may not solicit any such bids at any time while there are NIM Notes
outstanding.  If the Trust  Administrator  receives at least three bids for the related Trust  Collateral,
and one of such bids is equal to or greater  than the Par Value,  the Trust  Administrator  shall sell the
related Trust  Collateral to the highest bidder (a "Terminating  Auction  Purchaser") at the price offered
by the Terminating  Auction Purchaser (a "Mortgage Loan Terminating  Auction Price");  provided,  however,
that the Seller shall be  disqualified  from bidding and may not be a Terminating  Auction  Purchaser.  If
the Trust  Administrator  receives  less than three bids,  or does not receive any bid that is equal to or
greater than the Par Value, the Trust  Administrator  shall, on each six-month  anniversary of the initial
Terminating  Auction Date, repeat these auction  procedures until the Trust  Administrator  receives a bid
that is equal to or greater  than the Par  Value,  and upon  receipt  of such bid shall  sell the  related
Trust  Collateral to the  Terminating  Auction  Purchaser at that Mortgage Loan Auction  Price;  provided,
however,  that the Trust  Administrator  shall not be required to repeat these  auction  procedures on any
Distribution Date for any six-month  anniversary of the initial  Terminating Auction Date unless the Trust
Administrator  reasonably  believes that there is a reasonable  likelihood of receiving a bid in excess of
the Par Value.  The Trust  Administrator  shall give notice to the Rating  Agencies and each Servicer that
is servicing any of the related  Mortgage  Loans of the sale of the related Trust  Collateral  pursuant to
this  Section 11.01 (a "Terminating  Auction Sale") and of the Terminating  Auction Date.  Notwithstanding
anything to the contrary  herein,  the  Terminating  Auction  Purchaser  shall not be the  Depositor,  the
Seller or any of their respective Affiliates.

SECTION 11.02.    Determination of the Terminating Entity.

(a)      If any Servicer  intends to be the  Terminating  Entity,  such party must give written  notice to
the  Trust  Administrator  no  later  than  twenty  (20)  days  prior  to the  first  day of the  Optional
Termination  Notice  Period.  Such notice shall also indicate the Loan  Group(s) of the Mortgage  Loans to
be  repurchased.  Upon receiving  such notice,  the Trust  Administrator  shall  immediately  request from
DLJMC and DLJMC shall  deliver no later than  seventeen  (17) days prior to the first day of the  Optional
Termination  Notice Period a letter  indicating  whether or not DLJMC retains the servicing  rights to any
Mortgage Loan in any of the related Loan Groups.

(b)      (A)               With  respect to the  purchase  of the  Mortgage  Loans in Loan  Group 1,  Loan
      Group 2 and Loan  Group 3,  the Trust  Administrator  shall  determine the  "Terminating  Entity" as
      follows:

                                    (i)     DLJMC,  if it is  the  owner  of  the  servicing  rights  with
            respect to any such Mortgage Loans on the Optional Termination Date;

                                    (ii)    SPS,  if (a)  DLJMC is not the owner of the  servicing  rights
            with  respect to any such  Mortgage  Loans on the Optional  Termination  Date and (b) SPS is a
            Servicer  with respect to any such  Mortgage  Loans on the Optional  Termination  Date and SPS
            has given notice to the Trust Administrator pursuant to Section 11.02(a) above; or

                                    (iii)   the Majority  Servicer on the Optional  Termination  Date,  if
            (a) DLJMC is not the owner of the  servicing  rights with respect to any such  Mortgage  Loans
            on the Optional  Termination Date and (b) SPS has not given notice to the Trust  Administrator
            pursuant to Section 11.02(a) above.

                           (B)      With respect to the purchase of the  Mortgage  Loans in Loan  Group 4,
      the Trust Administrator shall determine the "Terminating Entity" as follows:

                                    (i)     DLJMC,  if it is  the  owner  of  the  servicing  rights  with
            respect to any such Mortgage Loans on the Optional Termination Date;

                                    (ii)    SPS,  if (a)  DLJMC is not the owner of the  servicing  rights
            with  respect to any such  Mortgage  Loans on the Optional  Termination  Date and (b) SPS is a
            Servicer  with respect to any such  Mortgage  Loans on the Optional  Termination  Date and SPS
            has given notice to the Trust Administrator pursuant to Section 11.02(a) above; or

                                    (iii)   the Majority  Servicer on the Optional  Termination  Date,  if
            (a) DLJMC is not the owner of the  servicing  rights with respect to any such  Mortgage  Loans
            on the Optional  Termination Date and (b) SPS has not given notice to the Trust  Administrator
            pursuant to Section 11.02(a) above.

(c)      No later  than  fifteen  (15)  days  prior to the first day of the  Optional  Termination  Notice
Period,  the Trust  Administrator  shall provide  notice to each Servicer that is a servicer of any of the
Mortgage  Loans in the related  Loan  Group(s) of the  identity  of the  Terminating  Entity for such Loan
Group(s).

SECTION 11.03.    Procedure Upon Optional Termination or Terminating Auction Sale.

(a)      In case of any Optional  Termination,  the Terminating  Entity shall, no later than ten (10) days
prior  to the  first  day of the  Optional  Termination  Notice  Period,  notify  the  Trustee  and  Trust
Administrator  of such Optional  Termination  Date and of the  applicable  purchase  price of the Mortgage
Loans to be  purchased.  Upon  purchase  by the  Terminating  Entity of any  Mortgage  Loans  pursuant  to
Section 11.01,  the Trust  Administrator shall notify each Servicer that is servicing any of such Mortgage
Loans (and with respect to the purchase of the Group 4 Loans, the Swap Counterparty) of such purchase.

(b)      Any  purchase  of the  Mortgage  Loans by the  Terminating  Entity  shall be made on an  Optional
Termination  Date by deposit of the  applicable  purchase  price into the  Certificate  Account before the
Distribution  Date on which such  purchase is  effected.  Upon  receipt by the Trust  Administrator  of an
Officer's  Certificate of the Terminating  Entity certifying as to the deposit of such purchase price into
the  Certificate  Account,  the Trustee,  the Trust  Administrator  and each  co-trust  administrator  and
separate trust  administrator,  if any, then acting as such under this Agreement,  shall, upon request and
at the  expense of the  Terminating  Entity  execute  and  deliver  all such  instruments  of  transfer or
assignment,  in each case without recourse,  as shall be reasonably requested by the Terminating Entity to
vest title in the  Terminating  Entity in the Mortgage Loans so purchased and shall transfer or deliver to
the Terminating  Entity the purchased  Mortgage Loans. Any  distributions on the Mortgage Loans which have
been  subject to an  Optional  Termination  received  by the Trust  Administrator  subsequent  to (or with
respect to any period  subsequent to) the Optional  Termination  Date shall be promptly  remitted by it to
the Terminating Entity.

(c)      Any purchase of the Trust Collateral by the related  Terminating  Auction Purchaser shall be made
on an  Terminating  Auction  Date by receipt  of the Trust  Administrator  of the  related  Mortgage  Loan
Terminating  Auction  Price from the  Terminating  Auction  Purchaser,  and deposit of such  Mortgage Loan
Terminating  Auction  Price  into  the  Certificate   Account  by  the  Trust  Administrator   before  the
Distribution  Date on which such  purchase  is  effected.  Upon  deposit of such  purchase  price into the
Certificate  Account,  the  Trustee  and the  Trust  Administrator  and each  co-trust  administrator  and
separate trust  administrator,  if any, then acting as such under this Agreement,  shall, upon request and
at the expense of the Terminating  Auction  Purchaser execute and deliver all such instruments of transfer
or  assignment,  in each case  without  recourse,  as shall be  reasonably  requested  by the  Terminating
Auction  Purchaser  to vest  title  in the  Terminating  Auction  Purchaser  in the  Trust  Collateral  so
purchased  and shall  transfer  or  deliver to the  Terminating  Auction  Purchaser  the  purchased  Trust
Collateral.

(d)      Notice  of the  Distribution  Date on which the Trust  Administrator  anticipates  that the final
distribution  shall be made on a Class of  Certificates  (whether upon Optional  Termination,  Terminating
Auction Sale or  otherwise),  shall be given  promptly by the Trust  Administrator  by first class mail to
Holders of the  affected  Certificates.  Such notice  shall be mailed no earlier than the 15th day and not
later than the 10th day preceding the applicable  Optional  Termination Date,  Terminating Auction Date or
date of final  distribution,  as the case may be. Such notice  shall  specify  (i) the  Distribution  Date
upon which final  distribution on the affected  Certificates shall be made upon presentation and surrender
of such  Certificates  at the  office  or  agency  therein  designated,  (ii) the  amount  of  such  final
distribution  and  (iii) that  the Record  Date  otherwise  applicable  to such  Distribution  Date is not
applicable,  such  distribution  being made only upon  presentation and surrender of such  Certificates at
the  office or agency  maintained  for such  purposes  (the  address  of which  shall be set forth in such
notice).

(e)      In the event  that any  Certificateholders  shall not  surrender  Certificates  for  cancellation
within  six  months  after  the  date  specified  in  the  above  mentioned  written  notice,   the  Trust
Administrator  shall give a second written notice to the remaining  such  Certificateholders  to surrender
their  Certificates for cancellation and receive the final  distribution  with respect thereto.  If within
six  months  after  the  second  notice  all  the  Certificates   shall  not  have  been  surrendered  for
cancellation,  the  Trust  Administrator  may take  appropriate  steps,  or may  appoint  an agent to take
appropriate   steps,  to  contact  the  remaining   Certificateholders   concerning   surrender  of  their
Certificates,  and the cost thereof  shall be paid out of the funds and other assets which remain  subject
to the Trust Fund.

(f)      Notwithstanding  anything to the contrary  herein,  the occurrence of an Optional  Termination or
Terminating  Auction  Sale  shall be  subject  to,  and  shall in no way  adversely  affect  the  right of
GreenPoint to continue  servicing and collecting its Servicing Fee for any  GreenPoint  Serviced  Mortgage
Loan that remains  outstanding at the time of such Optional  Termination  or  Terminating  Auction Sale or
the right of Wells  Fargo to continue  servicing  and  collecting  its  Servicing  Fee for any Wells Fargo
Serviced Mortgage Loan that remains outstanding at the time of such Optional Termination.

SECTION 11.04.    Additional Termination Requirements.

(a)      In the event the Terminating  Entity  exercises its purchase option pursuant to  Section 11.01(A)
or a Terminating  Auction Sale shall have occurred pursuant to  Section 11.01(c),  the related  subsidiary
REMIC shall be terminated in accordance  with the following  additional  requirements,  unless the Trustee
and the Trust  Administrator  have received an Opinion of Counsel to the effect that the failure to comply
with  the  requirements  of this  Section 11.04 will  not  (i) result  in the  imposition  of  taxes  on a
"prohibited  transaction"  of any REMIC created  hereunder,  as described in  Section 860F of the Code, or
(ii) cause  any REMIC  created  hereunder to fail to qualify as a REMIC at any time that any  Certificates
are outstanding:

(i)      within  90  days  prior  to the  final  Distribution  Date  set  forth  in the  notice  given  by
         Terminating  Entity under  Section 11.03,  the Holder of the Residual  Certificates shall adopt a
         plan of complete liquidation for the related REMIC; and

(ii)     at or after the time of adoption of any such plan of complete  liquidation  for such REMIC and at
         or prior to the final  Distribution  Date, the Trustee shall sell all of the assets of such REMIC
         to the Depositor for cash.

(b)      Upon the exercise of an Optional  Termination  by the  Terminating  Entity or upon the occurrence
of a  Terminating  Auction  Sale in respect of either  REMIC I or  REMIC II,  as  applicable,  pursuant to
paragraph  (a) of  this  Section 11.04,  followed  by  the  exercise  of an  Optional  Termination  by the
Terminating  Entity or upon the  occurrence  of a  Terminating  Auction  Sale in respect of the  remaining
subsidiary  REMIC (the  "Remaining  Subsidiary  REMIC")  pursuant to  Section 11.01,  each remaining REMIC
shall be terminated in accordance with the following additional  requirements,  unless the Trustee and the
Trust  Administrator  have  received  an Opinion of Counsel to the effect  that the failure to comply with
the  requirements  of this  Section 11.04 will  not (i) result in the imposition of taxes on a "prohibited
transaction"  of a REMIC,  as described in  Section 860F  of the Code,  or  (ii) cause  any REMIC  created
hereunder to fail to qualify as a REMIC at any time that any Certificates are outstanding:

(i)      concurrently  with the adoption of the plan of complete  liquidation of the Remaining  Subsidiary
         REMIC,  as set  forth  in  paragraph  (a) of  this  Section 11.04,  the  Holder  of the  Residual
         Certificates,  as  applicable,  shall  adopt a plan of  complete  liquidation  of each  remaining
         REMIC; and

(ii)     at or  after  the time of  adoption  of any  such  plan of  complete  liquidation  for each  such
         remaining  REMIC, at or prior to the final  Distribution  Date of the Remaining  Subsidiary REMIC
         to be terminated,  the Trustee shall sell all of the assets of each such  remaining  REMIC to the
         Depositor for cash.

(c)      By its  acceptance of a Residual  Certificate,  the Holder  thereof hereby agrees to adopt such a
plan of complete  liquidation  and to take such other action in connection  therewith as may be reasonably
required to liquidate and otherwise terminate any REMIC created pursuant to this Agreement.

                                               ARTICLE XII

(iii)    to modify,  eliminate  or add to any of its  provisions  to such extent as shall be  necessary or
         desirable  to  maintain  the  qualification  of the Trust  Fund as a REMIC at all times  that any
         Certificate  is  outstanding  or to avoid or minimize the risk of the  imposition  of any federal
         income tax on the Trust Fund  pursuant to the Code that would be a claim  against the Trust Fund,
         provided  that the Trustee has  received an Opinion of Counsel to the effect that (A) such action
         is  necessary or desirable  to maintain  such  qualification  or to avoid or minimize the risk of
         the imposition of any such federal  income tax and (B) such action will not adversely  affect the
         status of the Trust Fund as a REMIC or  adversely  affect in any material  respect the  interests
         of any Certificateholder,

         Section 12.01(a)(v) shall  not be  deemed  to  adversely  affect  in  any  material  respect  the
         interests of any  Certificateholder  if a letter is obtained from each Rating Agency stating that
         such amendment would not result in the  downgrading or withdrawal of the respective  ratings then
         assigned to the Certificates; or to comply with the provisions of Regulation AB.

received  on or with  respect  to  Mortgage  Loans are  required  to be  distributed  with  respect to any
Certificate without the consent of the Holder of such Certificate,  (ii) adversely  affect in any material
respect the  interests  of the Holders of a Class of  Certificates  in a manner other than as set forth in
(i) above  without  the  consent of the Holders of  Certificates  evidencing  not less than 66 2/3% of the
Voting Rights of such Class,  (iii) reduce  the aforesaid  percentages  of Voting  Rights,  the holders of
which are  required  to consent  to any such  amendment  without  the  consent  of 100% of the  Holders of
Certificates of the  Class affected  thereby,  (iv) change the percentage of the Stated Principal  Balance
of the Mortgage Loans specified in  Section 11.01(a) relating  to optional  termination of the Trust Fund,
(v)  change  the  percentage  of  the  Stated  Principal  Balance  of  the  Mortgage  Loans  specified  in

                  It  shall  not  be  necessary   for  the  consent  of   Certificateholders   under  this
Section 12.01  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 Trust Administrator may prescribe.

(c)      This  Agreement  may be amended  from time to time by the  Depositor,  the Master  Servicer,  the
Special  Servicer,  the Servicers,  the Trust  Administrator and the Trustee for the purpose of making one
or more REMIC elections with respect to one or more Classes of  Certificates  delivered to the Trustee and
issuing  one or  more  additional  classes  of  certificates  representing  interests  in the  Classes  of
Certificates  delivered to the Trustee;  provided,  however,  such amendment  shall require the consent of
100% of the Holders of the Certificates of the Class or Classes  delivered to the Trust  Administrator and

furnish  written  notification  of the  substance  of such  amendment to each  Certificateholder,  and the
Rating Agencies.

(e)      Prior to the  execution  of any  amendment to this  Agreement,  each of the Trustee and the Trust
Administrator  shall  receive  and be  entitled  to  conclusively  rely on an Opinion  of Counsel  (at the
expense of the Person seeking such  amendment)  stating that the execution of such amendment is authorized
and  permitted  by this  Agreement.  The  Trustee  and the  Trust  Administrator  may,  but  shall  not be
obligated to, enter into any such amendment which affects the Trustee's or the Trust  Administrator's  own
rights, duties or immunities under this Agreement.

(f)      The Master  Servicer  and the Trust  Administrator  may consent to any  amendment of a Designated
Servicing  Agreement to make any other provisions with respect to matters or questions  arising under such
Designated  Servicing  Agreement  or  this  Agreement  that  are  not  materially  inconsistent  with  the
provisions of such  Designated  Servicing  Agreement and this  Agreement,  provided that such action shall
not adversely  affect in any material respect the interests of any  Certificateholder  or cause an Adverse
REMIC Event. Any amendment  pursuant to this  Section 12.01(f) shall  not be deemed to adversely affect in
any material  respect the  interests of any  Certificateholders  if a letter is obtained  from each Rating
Agency  stating that such  amendment  would not result in the  downgrading or withdrawal of the respective
ratings then assigned to the Certificates.

(g)      Neither the Master  Servicer  nor the Trust  Administrator  shall  consent to any  amendment of a
Designated  Servicing  Agreement which shall adversely affect in any material respect the interests of the
Holders of a Class of  Certificates  without  the consent of the Holders of  Certificates  evidencing  not
less than 66-2/3% of the Voting Rights of such Class.

                  It  shall  not  be  necessary   for  the  consent  of   Certificateholders   under  this
Section 12.01 to  approve  the  particular  form  of any  proposed  amendment  of a  Designated  Servicing
Agreement,  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  Trust  Administrator  may
prescribe.

                  Promptly  after the  execution  of any  amendment to a  Designated  Servicing  Agreement
pursuant to  Section 12.01(f) or  (g), the Trust Administrator shall furnish,  upon written notice of such
amendment,  written  notification  of the substance of such amendment to each  Certificateholder,  and the
Rating Agencies.

(h)      Notwithstanding  any other provision of this Agreement,  no amendment shall be made affecting the
rights of the Holders of the Class P Certificates to receive Assigned Prepayment  Premiums,  including any
amendment to Section 3.21, without the consent of 100% of the Holders of the Class P Certificates.

(i)      Notwithstanding  anything  to the  contrary  in this  Section 12.01,  the  Master  Servicer,  the
Special  Servicer,  the Servicers,  the Seller,  the Trust  Administrator and the Trustee shall reasonably
cooperate  with the  Depositor  and its  counsel to enter into such  amendments  or  modifications  to the
Agreement  as may be  necessary  to  comply  with  Regulation  AB and any  interpretation  thereof  by the
Commission.

(j)      Without the consent of the Swap  Counterparty,  the Seller and the Depositor shall not enter into
any  amendment  or  modification  of the terms and  provisions  of this  Agreement  if such  amendment  or
modification  would  materially  adversely  affect  the  rights  and  interests  of the Swap  Counterparty
hereunder.

SECTION 12.02.    Recordation of Agreement; Counterparts.

(a)      This  Agreement  (other than  Schedule I) 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 Mortgaged  Properties are situated,  and in any other  appropriate  public  recording office or
elsewhere.  Such  recordation,  if any,  shall be effected by the Depositor at its expense,  but only upon
direction by the Trustee  (acting at the  direction of the holders of  Certificates  evidencing a majority
of the  aggregate  Class  Principal  Balance)  accompanied  by an Opinion of Counsel  (at the  Depositor's
expense) to the effect  that  non-recordation  materially  and  adversely  affects  the  interests  of the
Certificateholders.

(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 12.03.    Governing Law.

                  THIS  AGREEMENT  SHALL BE GOVERNED BY AND CONSTRUED IN  ACCORDANCE  WITH THE LAWS OF THE
STATE OF NEW YORK,  WITHOUT REGARD TO THE CONFLICT OF LAW PRINCIPALS  THEREOF,  OTHER THAN SECTIONS 5-1401
AND 5-1402 OF THE NEW YORK GENERAL OBLIGATIONS LAW.

SECTION 12.04.    Intention of Parties.

(a)      It is the  express  intent of the  Depositor,  the  Seller,  the  Master  Servicer,  the  Special
Servicer,  the Servicers,  the Trust Administrator and the Trustee that (i) the conveyance by DLJMC of the
Mortgage  Loans  to the  Depositor  pursuant  to the  Assignment  and  Assumption  Agreement  and  (v) the
conveyance  by the  Depositor to the Trustee as provided for in  Section 2.01  of each of the Seller's and
Depositor's  right,  title and interest in and to the Mortgage  Loans be, and be construed as, an absolute
sale and  assignment by DLJMC to the  Depositor and by the Depositor to the Trustee of the Mortgage  Loans
for the benefit of the  Certificateholders.  Further,  it is not intended that any conveyance be deemed to
be a pledge of the Mortgage  Loans by DLJMC to the  Depositor or by the Depositor to the Trustee to secure
a debt or other  obligation.  However,  in the event that the  Mortgage  Loans are held to be  property of
DLJMC or the  Depositor,  as applicable,  or if for any reason the Assignment and Assumption  Agreement or
this  Agreement  is held or  deemed  to create a  security  interest  in the  Mortgage  Loans,  then it is
intended that (i) this  Agreement  shall also be deemed to be a security  agreement  within the meaning of
Articles 8 and 9 of the New York  Uniform  Commercial  Code and the Uniform  Commercial  Code of any other
applicable  jurisdiction;  (ii) the conveyances provided for in Section 2.01 shall be deemed to be a grant
by the Seller and the Depositor to the Trustee on behalf of the  Certificateholders,  to secure payment in
full of the Secured  Obligations  (as defined  below),  of a security  interest in all of the Seller's and
the  Depositor's  right  (including the power to convey title  thereto),  title and interest,  whether now
owned or hereafter  acquired,  in and to the Mortgage Loans,  including the Mortgage Notes, the Mortgages,
any related  insurance  policies and all other documents in the related  Mortgage Files, and all accounts,
contract rights,  general intangibles,  chattel paper,  instruments,  documents,  money, deposit accounts,
certificates  of  deposit,  goods,  letters of credit,  advices  of credit and  uncertificated  securities
consisting  of,  arising  from or relating  to (A) the  Mortgage  Loans,  including  with  respect to each
Mortgage  Loan, the Mortgage Note and related  Mortgage,  and all other  documents in the related  Trustee
Mortgage  Files,  and including any Qualified  Substitute  Mortgage  Loans;  (B) pool insurance  policies,
hazard  insurance  policies and any  bankruptcy  bond relating to the foregoing,  if  applicable;  (C) the
Certificate  Account;  (D) the Collection  Account;  (E) all amounts payable after the Cut-off Date to the
holders of the Mortgage Loans in accordance  with the terms thereof;  (F) all income,  payments,  proceeds
and products of the  conversion,  voluntary  or  involuntary,  of the  foregoing  into cash,  instruments,
securities  or other  property,  including  without  limitation  all  amounts  from  time to time  held or
invested  in the  Certificate  Account,  whether  in the form of cash,  instruments,  securities  or other
property;  and (G) all cash and non-cash  proceeds of any of the  foregoing;  (iii) the  possession by the
Trustee  or any  other  agent of the  Trustee  of  Mortgage  Notes or such  other  items  of  property  as
constitute  instruments,  money,  documents,  advices of credit,  letters of credit,  goods,  certificated
securities or chattel paper shall be deemed to be a  "possession  by the secured  party," or possession by
a purchaser  or a person  designated  by him or her,  for purposes of  perfecting  the  security  interest
pursuant to the Uniform Commercial Code (including,  without  limitation,  Sections 9-313,  8-313 or 8-321
thereof);  and  (iv) notifications  to persons  holding such property,  and  acknowledgments,  receipts or
confirmations from persons holding such property,  shall be deemed  notifications to, or  acknowledgments,
receipts or confirmations from, financial  intermediaries,  securities  intermediaries,  bailees or agents
(as  applicable)  of the Trustee for the purpose of perfecting  such security  interest  under  applicable
law. "Secured  Obligations" means (i) the rights of each  Certificateholder  to be paid any amount owed to
it under this  Agreement  and  (ii) all  other  obligations  of the Seller  and the  Depositor  under this
Agreement and the Assignment and Assumption Agreement.

(b)      The Seller and the  Depositor,  and, at the  Depositor's  direction,  the Master  Servicer or the
Servicers,  the Trustee and the Trust Administrator,  shall, to the extent consistent with this Agreement,
take such  reasonable  actions as may be necessary to ensure that, if this Agreement were deemed to create
a security  interest in the Mortgage Loans and the other property  described above, such security interest
would be deemed to be a  perfected  security  interest  of first  priority as  applicable.  The  Depositor
shall  prepare  and file,  at the  related  Servicer's  expense,  all filings  necessary  to maintain  the
effectiveness  of any original  filings  necessary  under the Uniform  Commercial Code as in effect in any
jurisdiction  to perfect the  Trustee's  security  interest in or lien on the  Mortgage  Loans,  including
without  limitation  (i) continuation  statements,  and (ii) such other statements as may be occasioned by
any  transfer of any  interest of the Master  Servicer or any  Servicer or the  Depositor  in any Mortgage
Loan.

SECTION 12.05.    Notices.

                  In addition to other notices  provided  under this  Agreement,  the Trust  Administrator
shall notify the Rating  Agencies in writing:  (a) of any  substitution  of any Mortgage Loan;  (b) of any

any amounts owing to a Class of  Certificates;  (d) any Event of Default under this Agreement;  and (e) in

SECTION 12.06.    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 12.07.    Limitation on Rights of Certificateholders.

                  The death or incapacity  of any  Certificateholder  shall not operate to terminate  this
Agreement or the Trust Fund, nor entitle such  Certificateholder's  legal representative or heirs to claim
an accounting  or to take any action or commence any  proceeding in any court for a petition or winding up
of the Trust Fund, or otherwise  affect the rights,  obligations  and liabilities of the parties hereto or
any of them.

                  No  Certificateholder  shall have any right to vote  (except as  provided  herein) 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.

                  No  Certificateholder  shall  have any  right by  virtue  or by  availing  itself of any
provisions  of this  Agreement to institute  any suit,  action or  proceeding  in equity or at law upon or
under or with  respect to this  Agreement,  unless  such Holder  previously  shall have given to the Trust
Administrator  a  written  notice of an Event of  Default  and of the  continuance  thereof,  as  provided
herein,  and  unless  the  Holders  of  Certificates  evidencing  not less than 25% of the  Voting  Rights
evidenced  by the  Certificates  shall also have made  written  request  upon the Trust  Administrator  to
institute  such action,  suit or  proceeding  in its own name as Trust  Administrator  hereunder and shall
have offered to the Trust  Administrator  such  reasonable  indemnity as it may require against the costs,
expenses,  and liabilities to be incurred  therein or thereby,  and the Trust  Administrator,  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 being  understood and intended,  and being  expressly
covenanted  by each  Certificateholder  with every other  Certificateholder  and the Trust  Administrator,
that no one or more Holders of  Certificates  shall have any right in any manner  whatever by virtue or by
availing  itself or themselves of any  provisions  of this  Agreement to affect,  disturb or prejudice the
rights of the Holders of any other of the  Certificates,  or to obtain or seek to obtain  priority over or
preference  to any other such Holder or to enforce any right  under this  Agreement,  except in the manner
herein  provided  and  for  the  common  benefit  of  all  Certificateholders.   For  the  protection  and
enforcement  of the  provisions  of this  Section 12.07,  each and every  Certificateholder  and the Trust
Administrator shall be entitled to such relief as can be given either at law or in equity.

SECTION 12.08.    Certificates Nonassessable and Fully Paid.

                  It is the intention of the  Depositor  that  Certificateholders  shall not be personally
liable  for  obligations  of the Trust  Fund,  that the  interests  in the Trust Fund  represented  by the
Certificates  shall be  nonassessable  for any  reason  whatsoever,  and that the  Certificates,  upon due
authentication  thereof by the Trust  Administrator  pursuant to this  Agreement,  are and shall be deemed
fully paid.

SECTION 12.09.    Protection of Assets.

                  Except  for   transactions   and  activities   entered  into  in  connection   with  the
securitization  that is the  subject  of this  agreement,  the  trust  created  by this  agreement  is not
authorized and has no power to:

(i)      borrow money or issue debt;

(ii)     merge with another entity, reorganize, liquidate or sell assets; or

(iii)    engage in any business or activities.

                  Each party to this  agreement  agrees  that it will not file an  involuntary  bankruptcy
petition  against the Trust Fund or initiate any other form of insolvency  proceeding until 366 days after
the Certificates have been paid.

SECTION 12.10.    Non-Solicitation.

                  From and  after the date of this  Agreement,  each of the  Depositor,  the  Seller,  the
Master Servicer,  the Servicers,  the Trust Administrator and the Trustee agrees that it will not take any
action  or  permit  or cause  any  action  to be  taken  by any of its  agents  or  affiliates,  or by any
independent  contractors  on  any  such  party's  behalf,  to  personally,   by  telephone,  by  mail,  or
electronically  by e-mail or through the Interest or otherwise,  solicit the borrower or obligor under any
Mortgage Loan to refinance the Mortgage Loan, in whole or in part.  Notwithstanding  the foregoing,  it is
understood  and agreed that neither  (i) promotions  undertaken by the Depositor,  the Seller,  the Master
Servicer,  any Servicer,  the Trust  Administrator  or the Trustee or any affiliate of any such party that
originates  mortgage  loans in the normal course,  which are directed to the general  public at large,  or
segments thereof,  including,  without  limitation,  mass mailings based on commercially  acquired mailing
lists or  newspaper,  radio and  television  advertisements  nor (ii) serving the  refinancing  needs of a
Mortgagor  who,  without  solicitation,  contacts  either party in  connection  with the refinance of such
Mortgage or Mortgage Loan, shall  constitute  solicitation  under this  Section 12.10,  provided,  that no
segment of the general  public shall  consist  primarily of the  borrowers or obligors  under the Mortgage
Loans. None of the Depositor,  the Seller, the Master Servicer,  any Servicer,  the Trust Administrator or
the  Trustee  shall  permit  the sale of the name of any  Mortgagor  or any  list of  names  that  consist
primarily of the Mortgages to any Person.

                                              ARTICLE XIII

                                          EXCHANGE ACT REPORTING

SECTION 13.01.    Commission Reporting.

                  The  Trust  Administrator,  each  Servicer  and the  Master  Servicer  shall  reasonably
cooperate with the Depositor in connection with the Trust's  satisfying the reporting  requirements  under
the Exchange  Act. The Trust  Administrator  shall  prepare on behalf of the Depositor any Forms 8-K, 10-D
and 10-K  customary for similar  securities as required by the Exchange Act and the rules and  regulations
of the Commission  thereunder,  and the Depositor shall sign and the Trust  Administrator  shall file (via
EDGAR) such Forms on behalf of the Depositor.

                  Form 10-D and Form 10-K require the  registrant to indicate (by checking  "yes" or "no")
that it "(1) has filed  all  reports  required  to be filed by  Section 13  or 15(d) of the  Exchange  Act
during the preceding 12 months (or for such shorter  period that the  registrant was required to file such
reports),  and (2) has been  subject to such  filing  requirements  for the past 90 days."  The  Depositor
hereby  represents to the Trust  Administrator  that, as of the Closing Date,  the Depositor has filed all
such  required  reports  during  the  preceding  12 months  and that it has been  subject  to such  filing
requirement  for the past  90 days.  The Depositor  shall notify the Trust  Administrator  in writing,  no
later than the fifth  calendar  day after the related  Distribution  Date with  respect to the filing of a
report on Form 10-D and no later than March 15th with  respect to the filing of a report on Form 10-K,  if
the answer to each  question  should be "no." The Trust  Administrator  shall be  entitled to rely on such
representations in preparing, executing and/or filing any such report.

SECTION 13.02.    Form 10-D Reporting

                  Within 15 days after each Distribution  Date (subject to permitted  extensions under the
Exchange  Act), the Trust  Administrator  shall prepare and file on behalf of the Trust Fund any Form 10-D
required  by the  Exchange  Act,  in form and  substance  as  required  by the  Exchange  Act.  The  Trust
Administrator  shall file each Form 10-D with a copy of the related Monthly  Statement  attached  thereto.
Any  disclosure  in  addition  to the Monthly  Statement  that is  required  to be  included on  Form 10-D
("Additional  Form 10-D  Disclosure")  shall be  reported  by the  parties  set forth on  Exhibit S to the
Depositor  and the Trust  Administrator  and  directed  and  approved  by the  Depositor  pursuant  to the
following  paragraph  and  the  Trust  Administrator  shall  have no duty  or  liability  for any  failure
hereunder to determine or prepare any  Additional  Form 10-D  Disclosure,  except as set forth in the next
paragraph.

                  As set  forth  on  Exhibit S  hereto,  within  five  calendar  days  after  the  related
Distribution  Date,  (i) the  parties  set  forth  thereon  shall be  required  to  provide  to the  Trust
Administrator   and  the  Depositor,   to  the  extent  known  by  a  responsible   officer  thereof,   in
EDGAR-compatible  form, or in such other form as otherwise agreed upon by the Trust Administrator and such
party,  the form and substance of any Additional  Form 10-D  Disclosure,  if applicable,  together with an
additional  disclosure   notification  in  the  form  of  Exhibit W  hereto  (an  "Additional   Disclosure
Notification")  and (ii) the  Depositor  shall approve,  as to form and substance,  or disapprove,  as the
case may be, the inclusion of the Additional  Form 10-D  Disclosure on Form 10-D.  The Depositor  shall be
responsible  for any  reasonable  fees and  expenses  assessed or incurred by the Trust  Administrator  in
connection with including any Additional Form 10-D Disclosure on Form 10-D pursuant to this paragraph.

                  After preparing the Form 10-D,  the Trust Administrator  shall forward  electronically a
draft copy of the  Form 10-D to the  Depositor as soon as  possible,  however,  in no event later than the
11th calendar day after the related  Distribution  Date.  Within two business  days of receipt,  but in no
event no later than the  Business  Day prior to the date  specified in the next  sentence,  the  Depositor
shall notify the Trust  Administrator  of any changes to or approval of such Form 10-D.  In the absence of
receipt of any  written  changes or  approval,  the Trust  Administrator  shall be entitled to assume that
such Form 10-D is in final form and the Trust  Administrator  may proceed with the execution filing of the
Form 10-D.  No  later  than  two  Business  Days  prior  to  the  15th  calendar  day  after  the  related
Distribution  Date, a duly authorized  representative of the Master Servicer shall sign the Form 10-D.  If
a Form 10-D  cannot be filed on time or if a previously  filed  Form 10-D  needs to be amended,  the Trust
Administrator  shall follow the  procedures  set forth in  Section 13.05.  Promptly (but no later than one
Business  Day) after  filing with the  Commission,  the Trust  Administrator  shall make  available on its
internet  website a final executed copy of each Form 10-D  prepared and filed by the Trust  Administrator.
Each party to this  Agreement  acknowledges  that the  performance  by the Master  Servicer  and the Trust
Administrator  of its duties under this  Section 13.02  related to the timely  preparation,  execution and
filing of Form 10-D is contingent  upon such parties  strictly  observing all applicable  deadlines in the
performance  of their  duties under this  Section 13.02.  Neither the Trust  Administrator  nor the Master
Servicer  shall have any liability for any loss,  expense,  damage or claim arising out of or with respect
to any failure to properly prepare,  timely execute and/or timely file such Form 10-D,  where such failure
results from the Trust  Administrator's  inability or failure to obtain or receive, on a timely basis, any
information  from any other party hereto needed to prepare,  arrange for execution or file such Form 10-D,
not resulting from its own negligence, bad faith or willful misconduct.

SECTION 13.03.    Form 10-K Reporting

                  Within 90 days after the end of each  fiscal year of the Trust or such  earlier  date as
may be required by the Exchange  Act (the "10-K Filing  Deadline")  (it being  understood  that the fiscal
year  for  the  Trust  ends  on  December  31st of  each  year),  commencing  in  March  2007,  the  Trust
Administrator  shall  prepare  and file on behalf  of the  Trust a  Form 10-K,  in form and  substance  as
required by the Exchange Act. Each such  Form 10-K  shall  include the  following  items,  in each case to
the extent they have been  delivered  to the Trust  Administrator  within the  applicable  time frames set
forth  in  this  Agreement,  the  related  Custodial  Agreements  and  the  related  Designated  Servicing

"Reporting  Servicer")  as described  under  Section 13.06,  (ii)(A) the  Assessment  of  Compliance  with
servicing  criteria  for  each  Reporting  Servicer  as  described  under  Section 13.07,  and  (B) if any
Reporting  Servicer's  Assessment  of  Compliance  identifies  any  material  instance  of  noncompliance,

Compliance is not included as an exhibit to such  Form 10-K,  disclosure  that such report is not included
and an  explanation  why such report is not  included,  (iii)(A)  the  Accountant's  Attestation  for each

discretion,  may omit  from the  Form 10-K  any  Item 1123  Certification,  Assessment  of  Compliance  or
Accountants  Attestation that is not required to be filed with such Form 10-K  pursuant to  Regulation AB.
Any  disclosure  or  information  in addition to (i) through (iv) above that is required to be included on
Form 10-K  ("Additional  Form 10-K Disclosure") shall be reported by the parties set forth on Exhibit Y to
the  Depositor  and Trust  Administrator  and  directed  and  approved  by the  Depositor  pursuant to the
following  paragraph  and  the  Trust  Administrator  shall  have no duty  or  liability  for any  failure
hereunder to determine or prepare any  Additional  Form 10-K  Disclosure,  except as set forth in the next
paragraph.

                  As set forth on Exhibit Y  hereto,  no later than March 1 of each year that the Trust is
subject to the Exchange  Act  reporting  requirements,  commencing  in 2007,  (i) the parties set forth on
Exhibit Y shall be required to provide to the Trust  Administrator and the Depositor,  to the extent known
by a responsible  officer  thereof,  in  EDGAR-compatible  form, or in such other form as otherwise agreed
upon by the Trust  Administrator  and such  party,  the form and  substance  of any  Additional  Form 10-K
Disclosure,  if applicable,  together with an Additional  Disclosure  Notification  and (ii) the Depositor
shall  approve,  as to form  and  substance,  or  disapprove,  as the case may be,  the  inclusion  of the
Additional  Form 10-K  Disclosure on Form 10-K.  The Depositor  shall be  responsible  for any  reasonable
fees and  expenses  assessed or incurred by the Trust  Administrator  in  connection  with  including  any
Additional Form 10-K Disclosure on Form 10-K pursuant to this paragraph.

                  After preparing the Form 10-K,  the Trust Administrator  shall forward  electronically a
draft copy of the Form 10-K to the Depositor  for review.  Within three (3) business days of receipt,  but
in no event later than March 25, the  Depositor  shall notify the Trust  Administrator  in writing  (which
may be  furnished  electronically)  of any  changes to or approval  of such  Form 10-K.  In the absence of
receipt of any written changes or approval the Trust  Administrator  shall be entitled to assume that such
Form 10-K  is in final  form.  No later than the close of business  on the 4th  Business  Day prior to the
10-K Filing Deadline,  the Depositor shall sign the Form 10-K and return an electronic or fax copy of such
signed  Form 10-K  (with an  original  executed  hard  copy to  follow  by  overnight  mail) to the  Trust
Administrator.  If a Form 10-K  cannot be filed on time or if a  previously  filed  Form 10-K  needs to be
amended,  the Trust  Administrator  shall follow the procedures set forth in Section 13.05.  Promptly (but
no later than 1  Business  Day) after  filing  with the  Commission,  the Trust  Administrator  shall make
available  on its  internet  website a final  executed  copy of each  Form 10-K  prepared and filed by the
Trust  Administrator.  The  parties  to this  Agreement  acknowledge  that the  performance  by the Master
Servicer  and the Trust  Administrator  of its  duties  under  this  Section 13.03  related  to the timely
preparation  and filing of Form 10-K is  contingent  upon such  parties  (and the  Custodians,  Designated
Servicers and any Additional  Servicer or other Servicing  Function  Participant)  strictly  observing all
applicable  deadlines  in  the  performance  of  their  duties  under  Article XIII.   Neither  the  Trust
Administrator  nor the Master  Servicer  shall have any liability for any loss,  expense,  damage or claim
arising out of or with  respect to any  failure to properly  prepare  and/or  timely file such  Form 10-K,
where such failure results from the Trust  Administrator's  inability or failure to obtain or receive,  on
a timely basis,  any information  from any other party hereto needed to prepare,  arrange for execution or
file such Form 10-K, not resulting from its own negligence, bad faith or willful misconduct.

SECTION 13.04.    Form 8-K Reporting

                  Within four (4) Business Days after the occurrence of an event  requiring  disclosure on
Form 8-K  (each  such  event,  a  "Reportable  Event"),  and if  requested  by the  Depositor,  the  Trust
Administrator  shall  prepare and file on behalf of the Trust any  Form 8-K,  as required by the  Exchange
Act,  provided that the Depositor  shall file the initial  Form 8-K in connection with the issuance of the
Certificates.  Any disclosure or information  related to a Reportable Event or that is otherwise  required
to be  included  on  Form 8-K  ("Form 8-K  Disclosure  Information")  shall be reported by the parties set
forth on  Exhibit  U to the  Depositor  and the Trust  Administrator  and  directed  and  approved  by the
Depositor  pursuant  to the  following  paragraph  and  the  Trust  Administrator  shall  have  no duty or
liability for any failure  hereunder to determine or prepare any Form 8-K  Disclosure  Information  or any
Form 8-K, except as set forth in the next paragraph.

                  As set forth on  Exhibit U  hereto,  for so long as the Trust is subject to the Exchange
Act  reporting  requirements,  no later than the end of business,  New York City time, on the 2nd Business
Day after the occurrence of a Reportable  Event (i) the parties to this  transaction  shall be required to
provide to the Trust  Administrator  and the  Depositor,  to the  extent  known by a  responsible  officer
thereof,  in  EDGAR-compatible  form,  or in  such  other  form as  otherwise  agreed  upon  by the  Trust
Administrator  and  such  party,  the  form and  substance  of any  Form 8-K  Disclosure  Information,  if
applicable,  together with an Additional Disclosure  Notification and (ii) the Depositor shall approve, as
to form and  substance,  or  disapprove,  as the case may be, the  inclusion  of the  Form 8-K  Disclosure
Information.  The  Depositor  shall be  responsible  for any  reasonable  fees and  expenses  assessed  or
incurred by the Trust  Administrator in connection with including any Form 8-K  Disclosure  Information on
Form 8-K pursuant to this paragraph.

                  After preparing the Form 8-K,  the Trust  Administrator  shall forward  electronically a
draft  copy of the  Form 8-K  to the  Depositor  for  review.  Promptly,  but no later  than the  close of
business  on the 3rd  business  day after the  Reportable  Event,  the  Depositor  shall  notify the Trust
Administrator  in writing of any  changes to or approval  of such  Form 8-K.  In the absence of receipt of
any written changes or approval,  the Trust  Administrator  shall be entitled to assume that such Form 8-K
is in final form and a duly  authorized  representative  of the Trust  Administrator  may proceed with the
execution  and filing of the Form 8-K.  A duly  authorized  representative  of the Master  Servicer  shall
sign the Form 8-K.  If a Form 8-K  cannot be filed on time or if a previously  filed  Form 8-K needs to be
amended,  the Trust  Administrator  shall follow the procedures set forth in Section 13.05.  Promptly (but
no later than one  Business  Day) after filing with the  Commission,  the Trust  Administrator  shall make
available on its internet  website a final executed copy of each Form 8-K  prepared and filed by the Trust
Administrator.   The  parties  to  this  Agreement   acknowledge   that  the   performance  by  the  Trust
Administrator  and the Master  Servicer  of its  duties  under  this  Section 13.04  related to the timely
preparation  and filing of Form 8-K is contingent  upon such parties  strictly  observing  all  applicable
deadlines in the  performance of their duties under this  Section 13.04.  Neither the Master  Servicer nor
the Trust  Administrator  shall have any liability for any loss,  expense,  damage or claim arising out of
or with respect to any failure to properly  prepare and/or timely file such  Form 8-K,  where such failure
results from the Trust  Administrator's  inability or failure to obtain or receive, on a timely basis, any
information  from any other party hereto needed to prepare,  arrange for execution or file such  Form 8-K,
not resulting from its own negligence, bad faith or willful misconduct.

SECTION 13.05.    Delisting; Amendment; Late Filing of Reports

                  On or before  January 30 of the first year in which the Trust  Administrator  is able to
do so  under  applicable  law,  the  Trust  Administrator  shall  prepare  and  file a Form 15  Suspension
Notification  relating  to the  automatic  suspension  of  reporting  in  respect  of the Trust  under the
Exchange Act.

                  In the event that the Trust  Administrator  is unable to timely file with the Commission
all or any required portion of any Form 8-K,  10-D or 10-K required to be filed by this Agreement  because
required  disclosure  information  was either not  delivered  to it or  delivered to it after the delivery
deadlines set forth in this  Agreement or for any other reason,  the Trust  Administrator  shall  promptly
notify  electronically  the  Depositor.  In the case of Form 10-D and 10-K,  the parties to this Agreement
shall  cooperate  to prepare  and file a Form  12b-25 and a 10-D/A and 10-K/A as  applicable,  pursuant to
Rule 12b-25 of the Exchange Act. In the case of Form 8-K,  the Trust Administrator  shall, upon receipt of
all  required  Form 8-K  Disclosure  Information  and upon the approval  and  direction of the  Depositor,
include  such  disclosure  information  on the next  Form 10-D.  In the event  that any  previously  filed
Form 8-K,  10-D or 10-K needs to be amended in connection with any additional  Form 10-D Disclosure (other
than for the purpose of  restating  the Monthly  Report),  the Trust  Administrator  shall  electronically
notify the  Depositor  and such parties shall  cooperate to prepare any  necessary  Form 8-K/A,  10-D/A or
10-K/A.  Any Form 15,  Form  12b-25  or any  amendment  to  Form 8-K  or 10-D  shall be  signed  by a duly
authorized  representative  of the Master  Servicer.  Any  amendment to  Form 10-K  shall be signed by the
Depositor.  The parties to this Agreement  acknowledge  that the  performance  by the Trust  Administrator
and the Master  Servicer of their duties under this  Section 13.05  related to the timely  preparation and
filing of Form 15, a Form 12b-25 or any amendment to Form 8-K,  10-D or 10-K is contingent  upon each such
party  performing  its duties under this  Section 13.05.  Neither the Trust  Administrator  nor the Master
Servicer  shall have any liability for any loss,  expense,  damage or claim arising out of or with respect
to any failure to properly  prepare  and/or timely file any such Form 15, Form 12b-25 or any amendments to
Forms 8-K, 10-D or 10-K,  where such failure results from the Trust  Administrator's  inability or failure
to obtain or receive,  on a timely basis,  any information  from any other party hereto needed to prepare,
arrange for  execution  or file such Form 15, Form 12b-25 or any  amendments  to Forms 8-K,  10-D or 10-K,
not resulting from its own negligence, bad faith or willful misconduct.

SECTION 13.06.    Annual Statements of Compliance

                  The  Master  Servicer,  the Trust  Administrator  and each  Servicer  shall  deliver  or
otherwise make available (and the Master Servicer,  the Trust  Administrator and each Servicer shall cause
any  Servicing  Function  Participant  engaged  by it to  deliver  or  otherwise  make  available)  to the
Depositor,  the Trustee  and the Trust  Administrator  on or before  March 1 of each year,  commencing  in
March 2007, an Officer's  Certificate  (an "Item 1123  Certificate")  stating,  as to the signer  thereof,
that (A) a review of such party's  activities  during the preceding  calendar year or portion  thereof and
of such party's  performance  under this Agreement,  or such other  applicable  agreement in the case of a
Servicing  Function  Participant,  has been made under such officer's  supervision  and (B) to the best of
such officer's  knowledge,  based on such review,  such party has fulfilled all its obligations under this
Agreement,  or such other applicable  agreement in the case of a Servicing  Function  Participant,  in all
material  respects  throughout  such 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.  Promptly  after  receipt of each such  Item 1123  Certificate,  the Depositor
shall review such Item 1123  Certificate and, if applicable,  consult with each such party, as applicable,
as to the nature of any failures by such party,  in the  fulfillment  of any of such  party's  obligations
hereunder or, in the case of an Additional  Servicer,  under such other  applicable  agreement,  provided,
however,  that Wells  Fargo,  in its  capacity  as a  Servicer,  shall only be  obligated  to provide  the
Item 1123  Officer's  Certificate to the Master  Servicer and the Master  Servicer shall forward such 1123
Officer's  Certificate  to the  Depositor,  the  Trustee  and the Trust  Administrator  or, if there is no
Master Servicer,  to the Depositor and the Depositor shall forward such 1123 Officer's  Certificate to the
Trustee and the Trust Administrator.

                  The Master  Servicer  shall include all annual  statements of compliance  received by it
from  each  Servicer  with  its  own  annual  statement  of  compliance  to  be  submitted  to  the  Trust
Administrator pursuant to this Section 13.06.

                  In the event the Master  Servicer,  the Trust  Administrator  or any Servicing  Function
Participant  engaged by any such party is terminated or resigns  pursuant to the terms of this  Agreement,
or any  applicable  agreement in the case of a Servicing  Function  Participant,  as the case may be, such
party  shall  provide an  Item 1123  Certificate  pursuant  to this  Section 13.06  or to such  applicable
agreement, as the case may be, notwithstanding any such termination, assignment or resignation.

                  The Master  Servicer  shall enforce any obligation of any  Designated  Servicer,  to the
extent set forth in the  related  Designated  Servicing  Agreement,  to deliver to the Master  Servicer an
Item 1123  Certificate as may be required  pursuant to the related  Designated  Servicing  Agreement.  The
Master  Servicer  shall  include such  Item 1123  Certificate  with its own  Item 1123  Certificate  to be
submitted to the Trust Administrator, the Depositor and the Trustee pursuant to this Section 13.06.

SECTION 13.07.    Annual Assessments of Compliance.

                  By  March 1 of each year,  commencing  in March  2007,  the Master  Servicer,  the Trust
Administrator and each Servicer,  each at its own expense, shall furnish or otherwise make available,  and
each such party shall  cause any  Servicing  Function  Participant  engaged by it to furnish or  otherwise
make available,  each at its own expense,  to the Trust  Administrator,  the Trustee and the Depositor,  a
report  on  an  assessment  of  compliance  with  the  Relevant  Servicing  Criteria  (an  "Assessment  of
Compliance") that contains (A) a statement by such party of its  responsibility  for assessing  compliance
with the Relevant Servicing  Criteria for each party as set forth on Exhibit R,  (B) a statement that such
party used the Relevant  Servicing  Criteria to assess  compliance with the Relevant  Servicing  Criteria,
(C) such party's  assessment of compliance with the Relevant  Servicing  Criteria as of and for the fiscal
year covered by the Form 10-K  required to be filed  pursuant to  Section 13.03,  including,  if there has
been any material instance of noncompliance  with the Relevant  Servicing  Criteria,  a discussion of each
such failure and the nature and status thereof,  and (D) a statement that a registered  public  accounting
firm has issued an  Accountant's  Attestation on such party's  Assessment of Compliance  with the Relevant
Servicing Criteria as of and for such period.

                  No later  than the end of each  fiscal  year for the Trust for which a 10-K is  required
to be filed,  each  Servicer and the Master  Servicer  shall each forward to the Trust  Administrator  the
name of each Servicing  Function  Participant  engaged by it and what Relevant  Servicing Criteria will be
addressed in the  Assessment of Compliance  prepared by such  Servicing  Function  Participant;  provided,
however,  that the Master Servicer need not provide  information to the Trust Administrator so long as the
Master  Servicer  and the Trust  Administrator  are the same  person.  When the Master  Servicer  and each
Servicer (or any Servicing  Function  Participant  engaged by them) submit their Assessments of Compliance
to the Trust  Administrator,  such parties shall also at such time include the  Assessments  of Compliance
(and Accountant's  Attestation)  pursuant to Section 13.08 of each Servicing Function  Participant engaged
by it;  provided,  however,  that Wells Fargo,  in its capacity as a Servicer,  shall only be obligated to
provide  disclosure  pursuant  to the first and  second  paragraphs  of this  Section 13.07  to the Master
Servicer and the Master  Servicer shall forward such items to the  appropriate  parties or, if there is no
Master  Servicer,  to the  Depositor  and the  Depositor  shall  forward such items to the Trustee and the
Trust Administrator.

                  Promptly  after receipt of each  Assessment of  Compliance,  the Depositor  shall review
each such report and, if  applicable,  consult with the Master  Servicer,  the Trust  Administrator,  each
Servicer and any Servicing Function  Participant  engaged by such parties as to the nature of any material
instance of noncompliance  with the Relevant  Servicing  Criteria by each such party. None of such parties
shall be  required  to deliver  any such  assessments  until  April 15 in any given year so long as it has
received written  confirmation  from the Depositor that a Form 10-K is not required to be filed in respect
of the Trust for the preceding calendar year.

                  The Master  Servicer  shall  include  all annual  reports on  assessment  of  compliance
received by it from the  Servicers  with its own  assessment  of  compliance  to be submitted to the Trust
Administrator pursuant to this Section 13.07.

                  In the event the Master  Servicer,  the Trust  Administrator  or any Servicing  Function
Participant  engaged by any such  party is  terminated,  assigns  its rights  and  obligations  under,  or
resigns pursuant to, the terms of this Agreement,  or any other applicable agreement,  as the case may be,
such party shall  provide a report on assessment of  compliance  pursuant to this  Section 13.07,  or such
other applicable agreement, notwithstanding any such termination, assignment of resignation.

Custodians,  to  the  extent  set  forth  in the  related  Designated  Servicing  Agreement  or  Custodial
Agreement,  as applicable,  to deliver to the Master Servicer an Assessment of Compliance  within the time
frame  set  forth  in,  and in such  form and  substance  as may be  required  pursuant  to,  the  related
Designated  Servicing Agreement or Custodial Agreement,  as applicable.  The Master Servicer shall include
such  Assessment  of  Compliance  with its own  Assessment  of  Compliance  to be  submitted  to the Trust
Administrator and the Trustee pursuant to this Section 13.07.

SECTION 13.08.    Accountant's Attestation

                  By  March 1  of  each  year,  commencing  in  2007,  the  Master  Servicer,   the  Trust
Administrator  and each Servicer,  each at its own expense,  shall cause,  and each such party shall cause
any Servicing  Function  Participant  engaged by it to cause, each at its own expense, a registered public
accounting firm (which may also render other services to the Master Servicer,  the Trust  Administrator or
a Servicer  or such other  Servicing  Function  Participants,  as the case may be) and that is a member of
the  American   Institute  of  Certified  Public  Accountants  to  furnish  a  report  (the  "Accountant's
Attestation")  to the Trust  Administrator  and the  Depositor,  to the effect that (i) it has  obtained a
representation  regarding  certain matters from the management of such party,  which includes an assertion
that  such  party  has  complied  with  the  Relevant  Servicing  Criteria,  and  (ii) on the  basis of an
examination  conducted by such firm in accordance  with standards for  attestation  engagements  issued or
adopted  by the  PCAOB,  it is  expressing  an opinion as to  whether  such  party's  compliance  with the
Relevant Servicing  Criteria was fairly stated in all material  respects,  or it cannot express an overall
opinion  regarding such party's  assessment of compliance  with the Relevant  Servicing  Criteria.  In the
event that an overall opinion cannot be expressed,  such registered  public accounting firm shall state in
such report why it was unable to express such an opinion.  Such report must be  available  for general use
and not contain restricted use language.

                  Promptly  after  receipt of such  Accountant's  Attestations  from the Master  Servicer,
each  Servicer,  each  Designated  Servicer,  each  Custodian,  the Trust  Administrator  or any Servicing
Function  Participant  engaged  by such  parties,  (i) the  Depositor  shall  review the  report  and,  if
applicable,  consult  with  such  parties  as to the  nature  of any  defaults  by  such  parties,  in the
fulfillment of any of each such party's  obligations  hereunder or under any other  applicable  agreement,
and (ii) the Trust  Administrator  shall  confirm that each  Assessment  of  Compliance is coupled with an
Accountant's  Attestation  meeting the requirements of this  Section 13.08 and notify the Depositor of any
exceptions.  None of such parties shall be required to deliver any such assessments  until April 15 in any
given year so long as it has received  written  confirmation  from the  Depositor  that a Form 10-K is not
required to be filed in respect of the Trust for the preceding calendar year.

                  The  Master  Servicer  shall  include  each  such  attestation  furnished  to it by  the
Servicers  with  its  own  attestation  to be  submitted  to the  Trust  Administrator  pursuant  to  this
Section 13.08.

                  In the  event  the  Master  Servicer,  the  Trust  Administrator,  the  Custodians,  any
Servicer or any Servicing  Function  Participant  engaged by any such party,  is  terminated,  assigns its
rights  and  duties  under,  or  resigns  pursuant  to the terms of,  this  Agreement,  or any  applicable
Custodial  Agreement,  Servicing  Agreement  or  sub-servicing  agreement,  as the case may be, such party
shall, at its sole expense,  cause a registered public accounting firm to provide an attestation  pursuant
to this  Section 13.08,  or  such  other  applicable  agreement,  notwithstanding  any  such  termination,
assignment or resignation.

                  The Master  Servicer shall enforce any  obligation of the  Designated  Servicers and the
Custodians,  to the  extent  set forth in the  related  Designated  Servicing  Agreement  and the  related
Custodial  Agreement,  as applicable,  to deliver to the Master Servicer an attestation as may be required
pursuant  to, the related  Designated  Servicing  Agreement  or Custodial  Agreement  as  applicable.  The
Master  Servicer  shall  include  each  such  attestation  with  its own  Accountant's  Attestation  to be
submitted to the Trust Administrator pursuant to this Section 13.08.

SECTION 13.09.    Sarbanes-Oxley Certification

                  Each  Form 10-K  shall  include a  certification  (the  "Sarbanes-Oxley  Certification")
required  to be  included  therewith  pursuant  to the  Sarbanes-Oxley  Act.  Each  Servicer,  the  Master
Servicer and the Trust Administrator shall provide,  and each Servicer,  the Master Servicer and the Trust
Administrator  shall cause any Servicing Function  Participant engaged by it to, provide to the Person who
signs the  Sarbanes-Oxley  Certification (the "Certifying  Person"),  by March 1 of each year in which the
Trust is subject to the  reporting  requirements  of the  Exchange Act and  otherwise  within a reasonable
period of time upon request,  a  certification  (each,  a "Back-Up  Certification"),  in the form attached
hereto as Exhibit V,  upon which the Certifying  Person,  the entity for which the Certifying  Person acts
as an officer,  and such entity's  officers,  directors and Affiliates  (collectively  with the Certifying
Person,  "Certification  Parties")  can  reasonably  rely.  The  Depositor  shall serve as the  Certifying
Person  on  behalf  of the  Trust.  In the event the  Master  Servicer,  the  Trust  Administrator  or any
Servicing  Function  Participant  engaged by such party is terminated or resigns  pursuant to the terms of
this Agreement,  or any applicable  Subservicing Agreement, as the case may be, such party shall provide a
Back-Up  Certification to the Certifying Person pursuant to this  Section 13.09 with respect to the period
of time it was subject to this Agreement or any applicable Subservicing Agreement, as the case may be.

                  The Master  Servicer shall enforce any obligation of the  Designated  Servicers,  to the
extent set forth in the  related  Designated  Servicing  Agreement,  to  deliver to the Master  Servicer a
certification  similar to the Back-Up  Certification as may be required pursuant to the related Designated
Servicing Agreement.

SECTION 13.10.    Indemnification

                  Each  party  required  to  deliver  an  Assessment  of  Compliance  and an  Accountant's
Attestation  and/or an Item 1123  Certification  under  Article XIII  (each, a  "Responsible  Party) shall

Neither this Certificate nor the Mortgage Loans are guaranteed or insured by any governmental agency or instrumentality.

This certifies that [_____________________________________________], is the registered owner of the Percentage Interest evidenced by this Certificate (obtained by dividing the denomination of this Certificate by the aggregate of the denominations of all Certificates of the Class to which this Certificate belongs) in certain monthly distributions with respect to a Trust Fund consisting primarily of the Mortgage Loans deposited by Credit Suisse First Boston Mortgage Securities Corp. (the “Depositor”). The Trust Fund was created pursuant to a Pooling and Servicing Agreement dated as of the Cut-off Date specified above (the “Agreement”) among Credit Suisse First Boston Mortgage Securities Corp., as depositor, DLJ Mortgage Capital, Inc., as seller, Wells Fargo Bank, N.A., as trust administrator, master servicer and servicer, U.S. Bank National Association, as trustee, and Select Portfolio Servicing, Inc., as a servicer and as special servicer. To the extent not defined herein, the capitalized terms used herein have the 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.

[For Privately Offered Certs only] [No transfer of this Certificate shall be made unless such transfer is made pursuant to an effective registration statement under the Securities Act and any applicable state securities laws or is exempt from the registration requirements under said Act and such laws. In the event that a transfer is to be made in reliance upon an exemption from the Securities Act and such laws, in order to assure compliance with the Securities Act and such laws, the Certificateholder desiring to effect such transfer and such Certificateholder’s prospective transferee shall each certify to the Trust Administrator in writing the facts surrounding the transfer and (i) deliver a letter in substantially the form of either Exhibit L and either (A) Exhibit M 1, provided that all of the Certificates of the Class shall be transferred to one investor or the Depositor otherwise consents to such transfer, or (B) Exhibit M-2 or (ii) there shall be delivered to the Trust Administrator at the expense of the transferor an Opinion of Counsel that such transfer may be made pursuant to an exemption from the Securities Act. The Holder hereof desiring to affect such transfer shall, and does hereby agree to, indemnify the Trustee, the Trust Administrator and the Depositor against any liability that may result if the transfer is not so exempt or is not made in accordance with such federal and state laws.]

Pursuant to Section 6.02(f) of the Agreement, no transfer of an ERISA-Restricted Certificate shall be made unless the Trustee shall have received either (i) a representation letter from the transferee of such ERISA-Restricted Certificate, acceptable to and in form and substance satisfactory to the Trust Administrator, to the effect that such transferee is not an employee benefit plan or arrangement subject to

C-3

Section 406 of ERISA or Section 4975 of the Code, or a person using the assets of any such plan or arrangement which representation letter shall not be an expense of the Trustee, the Trust Administrator or the Trust Fund, (ii) if the purchaser is an insurance company and the ERISA-Restricted Certificate has been the subject of an ERISA-Qualifying Underwriting, a representation that the purchaser is an insurance company which is purchasing such Certificates with funds contained in an “insurance company general account” (as such term is defined in Section V(e) of Prohibited Transaction Class Exemption 95-60 (“PTCE 95-60”)) and that the purchase and holding of such Certificate are covered under Sections I and III of PTCE 95-60 or (iii) in the case of any such ERISA-Restricted Certificate presented for registration in the name of an employee benefit plan subject to ERISA or Section 4975 of the Code (or comparable provisions of any subsequent enactments), or a person using such plan’s or arrangement’s assets, an Opinion of Counsel satisfactory to the Trust Administrator to the effect that the purchase or holding of such Certificate will not result in prohibited transactions under Section 406 of ERISA and/or Section 4975 of the Code and will not subject the Depositor, the Trustee, the Trust Administrator, the Master Servicer or any other Servicer to any obligation in addition to those undertaken in this Agreement, which Opinion of Counsel shall not be an expense of such parties or the Trust Fund. In the event the representations referred to in the preceding sentence are not furnished, such representation shall be deemed to have been made to the trustee by the transferee’s acceptance of an ERISA-Restricted Certificate or by any beneficial owner who purchases an interest in this certificate in book-entry form. In the event that a representation is violated, or any attempt to transfer an ERISA-Restricted Certificate to a plan or arrangement or person using a plan’s or arrangement’s assets is attempted without the delivery to the Trustee of the Opinion of Counsel described above, the attempted transfer or acquisition of this certificate shall be void and of no effect.

This Certificate shall not be entitled to any benefit under the Agreement or be valid for any purpose unless manually countersigned by an authorized signatory of the Trust Administrator.

This certifies that _____________________________, is the registered owner of the Percentage Interest evidenced by this Certificate (obtained by dividing the denomination of this Certificate by the aggregate of the denominations of all Certificates of the Class to which this Certificate belongs) in certain monthly distributions with respect to a Trust Fund consisting primarily of the Mortgage Loans deposited by Credit Suisse First Boston Mortgage Securities Corp. (the “Depositor”). The Trust Fund was created pursuant to a Pooling and Servicing Agreement dated as of the Cut-off Date specified above (the “Agreement”) among Credit Suisse First Boston Mortgage Securities Corp., as depositor, DLJ Mortgage Capital, Inc., as seller, Wells Fargo Bank, N.A., as trust administrator, master servicer and servicer, U.S. Bank National Association, as trustee, and Select Portfolio Servicing, Inc., as a servicer and as special servicer. To the extent not defined herein, the capitalized terms used herein have the 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.

No transfer of this Certificate shall be made unless such transfer is made pursuant to an effective registration statement under the Securities Act and any applicable state securities laws or is exempt from the registration requirements under said Act and such laws. In the event that a transfer is to be made in reliance upon an exemption from the Securities Act and such laws, in order to assure compliance with the Securities Act and such laws, the Certificateholder desiring to effect such transfer and such Certificateholder’s prospective transferee shall each certify to the Trust Administrator in writing the facts surrounding the transfer and (i) deliver a letter in substantially the form of either Exhibit L and either (A) Exhibit M-1, provided that all of the Certificates of the Class shall be transferred to one investor or the Depositor otherwise consents to such transfer, or (B) Exhibit M-2 or (ii) there shall be delivered to the Trust Administrator at the expense of the transferor an Opinion of Counsel that such transfer may be made pursuant to an exemption from the Securities Act. The Holder hereof desiring to effect such transfer shall, and does hereby agree to, indemnify the Trustee, the Trust Administrator and the Depositor against any liability that may result if the transfer is not so exempt or is not made in accordance with such federal and state laws.

Pursuant to the Agreement, no transfer of an ERISA-Restricted Certificate shall be made unless the Trust Administrator shall have received either (i) a representation letter from the transferee of such ERISA-Restricted Certificate, acceptable to and in form and substance satisfactory to the Trust Administrator, to the effect that such transferee is not an employee benefit plan or arrangement subject to

E-3

Section 406 of ERISA or Section 4975 of the Code, or a person using the assets of any such plan or arrangement which representation letter shall not be an expense of the Trustee, the Trust Administrator or the Trust Fund, (ii) if the purchaser is an insurance company and the ERISA-Restricted Certificate has been the subject of an ERISA-Qualifying Underwriting, a representation that the purchaser is an insurance company which is purchasing such Certificates with funds contained in an “insurance company general account” (as such term is defined in Section V(e) of Prohibited Transaction Class Exemption 95-60 (“PTCE 95-60”)) and that the purchase and holding of such Certificate are covered under Sections I and III of PTCE 95-60 or (iii) in the case of any such ERISA-Restricted Certificate presented for registration in the name of an employee benefit plan subject to ERISA or Section 4975 of the Code (or comparable provisions of any subsequent enactments), or a person using such plan’s or arrangement’s assets, an Opinion of Counsel satisfactory to the Trust Administrator to the effect that the purchase or holding of such Certificate will not result in prohibited transactions under Section 406 of ERISA and/or Section 4975 of the Code and will not subject the Depositor, the Trustee, the Trust Administrator, the Master Servicer or any other Servicer to any obligation in addition to those undertaken in this Agreement, which Opinion of Counsel shall not be an expense of such parties or the Trust Fund. In the event the representations referred to in the preceding sentence are not furnished, such representation shall be deemed to have been made to the Trust Administrator by the transferee’s acceptance of an ERISA-Restricted Certificate or by any beneficial owner who purchases an interest in this certificate in book-entry form. In the event that a representation is violated, or any attempt to transfer an ERISA-Restricted Certificate to a plan or arrangement or person using a plan’s or arrangement’s assets is attempted without the delivery to the Trust Administrator of the Opinion of Counsel described above, the attempted transfer or acquisition of this certificate shall be void and of no effect.

Reference is hereby made to the further provisions of this Certificate set forth following the signature page hereof, which further provisions shall for all purposes have the same effect as if set forth at this place.

This Certificate shall not be entitled to any benefit under the Agreement or be valid for any purpose unless manually countersigned by an authorized signatory of the Trust Administrator.

On any Distribution Date on which the Stated Principal Balance of Mortgage Loans in such Loan Groups as are specified in the Agreement are less than those percentages set forth in the Agreement, all remaining Mortgage Loans in such Loan Groups and all property acquired in respect of such Mortgage Loans may be purchased as provided in the Agreement. In the event that no such purchase occurs, the obligations and responsibilities created by the Agreement will terminate upon the later of the maturity or other liquidation (or any advance with respect thereto) of the last Mortgage Loan remaining in the Trust Fund or the disposition of all property in respect thereof and the distribution to Certificateholders of all amounts required to be distributed pursuant to the Agreement. In no event, however, will the trust created by the Agreement continue beyond the earlier of (i) the expiration of 21 years from the death of the last survivor of the descendants living at the date of the Agreement of a certain person named in the Agreement or (ii) the Distribution Date following the third anniversary of the scheduled maturity date of the Mortgage Loan having the latest scheduled maturity date as of the related Cut-off Date. Any term used herein that is defined in the Agreement shall have the meaning assigned in the Agreement, and nothing herein shall be deemed inconsistent with that meaning.

Agreement. 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 therefor 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 limited circumstances, without the consent of the Holders of any of the Certificates.

As provided in the Agreement and subject to certain limitations therein set forth, the transfer of this Certificate is registrable in the Certificate Register of the Trust Administrator upon surrender of this Certificate for registration of transfer at the Corporate Trust Office or the office or agency maintained by the Trust Administrator in New York, New York, accompanied by a written instrument of transfer in form satisfactory to the Trust Administrator and the Certificate Registrar duly executed by the holder hereof or such holder’s attorney duly authorized in writing, and thereupon one or more new Certificates of the same Class in authorized denominations and evidencing the same aggregate Percentage Interest in the Trust Fund will be issued to the designated transferee or transferees.

FORM OF TRANSFEREE AFFIDAVIT AND AGREEMENT

STATE OF	)
		: ss.:
COUNTY OF	)

[NAME OF OFFICER], being first duly sworn, deposes and says:

1. That he is [Title of Officer] or [Name of Owner] (record or beneficial owner (the “Owner”) of the Class [AR/AR-L] Certificates (the “Class [AR/AR-L] Certificates”)), a [savings institution] [corporation] duly organized and existing under the laws of [the State of ] [the United States], on behalf of which he makes this affidavit and agreement.

2. That the Owner (i) is not and will not be a “disqualified organization” as of [date of transfer] within the meaning of Section 860E(e)(5) of the Internal Revenue Code of 1986, as amended (the “Code”), (ii) will endeavor to remain other than a disqualified organization for so long as it retains its ownership interest in the Class [AR/AR-L] Certificates, and (iii) is acquiring the Class [AR/AR-L] Certificates for its own account. A “Permitted Transferee” is any person other than a “disqualified organization.” (For this purpose, a “disqualified organization” means the United States, any state or political subdivision thereof, any agency or instrumentality of any of the foregoing (other than an instrumentality all of the activities of which are subject to tax and, except for the Federal Home Loan Mortgage Corporation, a majority of whose board of directors is not selected by any such governmental entity) or any foreign government, international organization or any agency or instrumentality of such foreign government or organization, any rural electric or telephone cooperative, or any organization (other than certain farmers’ cooperatives) that is generally exempt from federal income tax unless such organization is subject to the tax on unrelated business taxable income).

3. That the Owner is aware (i) of the tax that would be imposed on transfers of Class [AR/AR-L] Certificates to disqualified organizations under the Code; (ii) that such tax would be on the transferor, or, if such transfer is through an agent (which person includes a broker, nominee or middleman) for a non-Permitted Transferee, on the agent; (iii) that the person otherwise liable for the tax shall be relieved of liability for the tax if the transferee furnishes to such person an affidavit that the transferee is a Permitted Transferee and, at the time of transfer, such person does not have actual knowledge that the affidavit is false; and (iv) that the Class [AR/AR-L] Certificates may be “noneconomic residual interests” within the meaning of Treasury regulations promulgated pursuant to the Code and that the transferor of a noneconomic residual interest will remain liable for any taxes due with respect to the income on such residual interest, if a significant purpose of the transfer was to enable the transferor to impede the assessment or collection of tax.

4. That the Owner is aware of the tax imposed on a “pass-through entity” holding Class [AR/AR-L] Certificates if at any time during the taxable year of the pass-through entity a non-Permitted Transferee is the record holder of an interest in such entity. (For this purpose, a “pass through entity” includes a regulated investment company, a real estate investment trust or common trust fund, a partnership, trust or estate, and certain cooperatives.)

5. That the Owner is aware that the Trustee will not register the Transfer of any Class [AR/AR-L] Certificates unless the transferee, or the transferee’s agent, delivers to it an affidavit and agreement, among other things, in substantially the same form as this affidavit and agreement. The

N-1

Owner expressly agrees that it will not consummate any such transfer if it knows or believes that any of the representations contained in such affidavit and agreement are false.

6. That the Owner has reviewed the restrictions set forth on the face of the Class [AR/AR-L] Certificates and the provisions of Section 6.02 of the Pooling and Servicing Agreement under which the Class [AR/AR-L] Certificates were issued. The Owner expressly agrees to be bound by and to comply with such restrictions and provisions.

7. That the Owner consents to any additional restrictions or arrangements that shall be deemed necessary upon advice of counsel to constitute a reasonable arrangement to ensure that the Class [AR/AR-L] Certificates will only be owned, directly or indirectly, by an Owner that is a Permitted Transferee.

That the Owner’s Taxpayer Identification Number is ________________.

9. That the Owner 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, any State thereof or the District of Columbia, or an estate or trust 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.

10. That no purpose of the Owner relating to the purchase of the Class [AR/AR-L] Certificate by the Owner is or will be to impede the assessment or collection of tax.

11. That the Owner has no present knowledge or expectation that it will be unable to pay any United States taxes owed by it so long as any of the Certificates remain outstanding.

12. That the Owner has no present knowledge or expectation that it will become insolvent or subject to a bankruptcy proceeding for so long as any of the Certificates remain outstanding.

13. That no purpose of the Owner relating to any sale of the Class [AR/AR-L] Certificate by the Owner will be to impede the assessment or collection of tax.

14. The Owner hereby agrees to cooperate with the Trustee and to take any action required of it by the Code or Treasury regulations thereunder (whether now or hereafter promulgated) in order to create or maintain the REMIC status of the Trust Fund.

15. That the Owner is not an employee benefit or other plan subject to the prohibited transaction provisions of 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”) (a “Plan”), or any other person (including an investment manager, a named fiduciary or a trustee of any Plan) acting, directly or indirectly, on behalf of or purchasing any Certificate with “plan assets” of any Plan.

16. The Owner hereby agrees that it will not take any action that could endanger the REMIC status of the Trust Fund or result in the imposition of tax on the Trust Fund unless counsel for, or acceptable to, the Trustee has provided an opinion that such action will not result in the loss of such REMIC status or the imposition of such tax, as applicable.

17. The Owner has provided financial statements or other financial information requested by the transferor in connection with the transfer of the Residual Certificates to permit the transferor to assess the financial capability of the Owner to pay any such taxes.

Ladies and Gentlemen:

This letter is delivered to you in connection with the sale by _________________ (the “Seller”) to ____________________________________ (the “Purchaser”) of a _______% Percentage Interest in the above referenced Certificates, pursuant to Section 6.02 of the Pooling and Servicing Agreement dated as of July 1, 2006, among Credit Suisse First Boston Mortgage Securities Corp., as depositor, DLJ Mortgage Capital, Inc., as seller, Select Portfolio Servicing, Inc., as a servicer and as special servicer, U.S. Bank National Association, as trustee, and Wells Fargo Bank, N.A., as a servicer, master servicer and trust administrator (the “Pooling and Servicing Agreement”). All terms used herein and not otherwise defined shall have the meanings set forth in the Pooling and Servicing Agreement. The Seller hereby certifies, represents and warrants to, and covenants with, the Depositor and the Trustee that:

6. The Purchaser has represented to the Seller that, if the Certificate constitutes a noneconomic residual interest, it (i) understands that as holder of a noneconomic residual interest it may

                     CALCULATION OF REMIC I Y PRINCIPAL REDUCTION AMOUNTS

               REMIC I Y Principal  Reduction  Amounts:  For any Distribution Date the amounts
by which the principal  balances of the Class Y-1,  Class Y-2,  Class Y-3, Class Y-4 and Class
Y-5 Certificates  respectively  will be reduced on such distribution date by the allocation of
Realized Losses and the distribution of principal, determined as follows:

First for each of Group 1,  Group 2,  Group 3,  Group 4 and  Group 5  determine  the  weighted
average  pass-through  rate for that Group for  distributions of interest that will be made on
the next succeeding  Distribution  Date (the "Group Interest Rate").  The Principal  Reduction
Amount  for each of the Class Y  Certificates  will be  determined  pursuant  to the  "Generic
solution  for the REMIC I Y  Principal  Reduction  Amounts"  set  forth  below  (the  "Generic
Solution")  by making  identifications  among the actual  Groups and their related Class Y and
Class Z  Certificates  and  weighted  average  pass-through  rates and the Groups named in the
Generic Solution and their related Class Y and Class Z Certificates as follows:

A. Determine  which Group has the lowest Group  Interest  Rate.  That Group will be identified
with  Group AA  and the  Class Y and  Class  Z  Certificates  related  to that  Group  will be
respectively  identified  with the Class YAA and Class ZAA  Certificates.  The Group  Interest
Rate for that Group will be  identified  with J%. If two or more Groups have the lowest  Group
Interest Rate pick one for this  purpose,  subject to the  restriction  that each Group may be
picked only once in the course of any such  selections  pursuant to  paragraphs A through E or
this definition.

B.  Determine  which  Group has the second  lowest  Group  Interest  Rate.  That Group will be
identified  with Group BB and the Class Y and Class Z Certificates  related to that Group will
be respectively  identified with the Class BB and Class ZBB  Certificates.  The Group Interest
Rate for  that  Group  will be  identified  with K%.  If two or more  Groups  have the  second
lowest Group  Interest Rate pick one for this purpose,  subject to the  restriction  that each
Group may be picked only once in the course of any such  selections  pursuant to  paragraphs A
through E or this definition.

C.  Determine  which  Group has the third  lowest  Group  Interest  Rate.  That  Group will be
identified  with Group CC and the Class Y and Class Z Certificates  related to that Group will
be  respectively  identified  with  the  Class YCC  and  Class ZCC  Certificates.   The  Group
Interest  Rate for that  Group  will be  identified  with L%. If two or more  Groups  have the
third lowest Group Interest Rate pick one for this purpose,  subject to the  restriction  that
each  Group  may be  picked  only  once in the  course  of any  such  selections  pursuant  to
paragraphs A through E or this definition.

D.  Determine  which  Group has the fourth  lowest  Group  Interest  Rate.  That Group will be
identified  with Group DD and the Class Y and Class Z Certificates  related to that Group will
be  respectively  identified  with  the  Class YDD  and  Class ZDD  Certificates.   The  Group
Interest  Rate for that  Group  will be  identified  with M%. If two or more  Groups  have the
fourth lowest Group Interest Rate pick one for this purpose,  subject to the restriction  that
each  Group  may be  picked  only  once in the  course  of any  such  selections  pursuant  to
paragraphs A through E or this definition.

E.  Determine  which  Group has the fifth  lowest  Group  Interest  Rate.  That  Group will be
identified  with Group EE and the Class Y and Class Z Certificates  related to that Group will
be  respectively  identified  with  the  Class YEE  and  Class ZEE  Certificates.   The  Group
Interest  Rate for that  Group  will be  identified  with N%. If two or more  Groups  have the
fifth lowest Group Interest Rate pick one for this purpose,  subject to the  restriction  that
each  Group  may be  picked  only  once in the  course  of any  such  selections  pursuant  to
paragraphs A through E or this definition.

Second,  apply the  Generic  Solution  set forth  below to  determine  the REMIC I Y Principal
Reduction Amounts for the Distribution Date using the identifications made above.

               Generic  Solution  for  the  REMIC I Y  Principal  Reduction  Amounts:  For any
Distribution  Date,  the amounts by which the principal  balances of the Class YAA, Class YBB,
Class  YCC,  Class  YDD and  Class  YEE  Certificates  respectively  will be  reduced  on such
Distribution  Date by the  allocation of Realized  Losses and the  distribution  of principal,
determined as follows:

The purpose of the foregoing definitional provisions together with the related provisions
allocating Realized Losses and defining the Class Y and Class Z Principal Distribution
Amounts is to accomplish the following goals in the following order of priority:

1.      Making the ratio of (Yn - ΔYn ) to (Y11 - ΔY11 ) equal to γ1 after taking
        account of the allocation Realized Losses and the distributions that will be made
        through the end of the Distribution Date to which such provisions relate and assuring
        that the Principal Reduction Amount for each of the Class YAA, Class YBB, Class YCC,
        Class YDD, Class YEE, Class ZAA, Class ZBB, Class ZCC, Class ZDD and Class ZEE
        Certificates is greater than or equal to zero for such Distribution Date;
2.      Making the Class YAA Principal Balance less than or equal to 0.0005 of the sum of the
        Class YAA and Class ZAA Principal Balances, the Class YBB Principal Balance less than
        or equal to 0.0005 of the sum of the Class YBB and Class ZBB Principal Balances, the
        Class YCC Principal Balance less than or equal to 0.0005 of the sum of the Class YCC
        and Class ZCC Principal Balances, the Class YDD Principal Balance less than or equal
        to 0.0005 of the sum of the Class YDD and Class ZDD Principal Balances and the Class
        YEE Principal Balance less than or equal to 0.0005 of the sum of the Class YEE and
        Class ZEE Principal Balances in each case after giving effect to allocations of
        Realized Losses and distributions to be made through the end of the Distribution Date
        to which such provisions relate; and
3.      Making the larger of (a) the fraction whose numerator is (Yn - ΔYn ) and whose
        denominator is the sum of (Yn - ΔYn) and (Zn - ΔZn) and (b) the fraction whose
        numerator is (Y11 - ΔY11) and whose denominator is the sum of (Y11 - ΔY11) and (Z11 -
        ΔZ11) as large as possible while remaining less than or equal to 0.0005.

In the event of a failure of the foregoing portion of the  definition of ClassY Principal
Reduction Amount to accomplish both of goals 1 and 2 above, the amounts thereof should be
adjusted to so as to accomplish such goals within the requirement that each REMIC I Y
Principal Reduction Amount must be less than or equal to the sum of (a) the Principal
Realized Losses to be allocated on the related Distribution Date for the related Pool
remaining after the allocation of such Realized Losses to the related class of ratio-strip
principal only certificates, if any, and (b) the remainder of the Available Distribution
Amount for the related Pool or after reduction thereof by the distributions to be made on
such Distribution Date (i) to the related class of ratio-strip principal only certificates,
if any, (ii) to the related class of ratio-strip interest only certificates, if any, and
(iii) in respect of interest on the related Class Y and Class Z Certificates, or, if both of
such goals cannot be accomplished within such requirement, such adjustment as is necessary
shall be made to accomplish goal 1 within such requirement.  In the event of any conflict
among the provisions of the definition of the REMIC I Y Principal Reduction Amounts, such
conflict shall be resolved on the basis of the goals and their priorities set forth above
within the requirement set forth in the preceding sentence.  If the formula allocation of
ΔY11 among ΔYj, ΔYk, ΔYl and ΔYm cannot be achieved because one or more of ΔYj, ΔYk, ΔYl and
ΔYm, as so defined is greater than the related one of  ΔPj, ΔPk, ΔPl and ΔPm, such an
allocation shall be made as close as possible to the formula allocation within the
requirement that ΔYj < ΔPj, ΔYk < ΔPk, ΔYl < ΔPl, ΔYm < ΔPm and ΔYm < ΔPm.

The purpose of the foregoing definitional provisions together with the related provisions
allocating Realized Losses and defining the Class Y and Class Z Principal Distribution
Amounts is to accomplish the following goals in the following order of priority:

1.      Making the ratio of (Y52 - ΔY52 ) to (Y51 - ΔY51 ) equal to γ5 after
        taking account of the allocation Realized Losses and the distributions that will be
        made through the end of the Distribution Date to which such provisions relate and
        assuring that the Principal Reduction Amount for each of the Class YAA, Class YBB,
        Class YCC, Class YDD, Class YEE, Class YFF, Class YGG, Class YHH, Class ZAA, Class
        ZBB, Class ZCC, Class ZDD, Class ZEE, Class ZFF, Class ZGG and Class ZHH Certificates
        is greater than or equal to zero for such Distribution Date;
2.      Making the Class YAA Principal Balance less than or equal to 0.0005 of the sum of the
        Class YAA and Class ZAA Principal Balances, the Class YBB Principal Balance less than
        or equal to 0.0005 of the sum of the Class YBB and Class ZBB Principal Balances, the
        Class YCC Principal Balance less than or equal to 0.0005 of the sum of the Class YCC
        and Class ZCC Principal Balances, the Class YDD Principal Balance less than or equal
        to 0.0005 of the sum of the Class YDD and Class ZDD Principal Balances, the Class YEE
        Principal Balance less than or equal to 0.0005 of the sum of the Class YEE and Class
        ZEE Principal Balances, the Class YFF Principal Balance less than or equal to 0.0005
        of the sum of the Class YFF and Class ZFF Principal Balances, the Class YGG Principal
        Balance less than or equal to 0.0005 of the sum of the Class YGG and Class ZGG
        Principal Balances and the Class YHH Principal Balance less than or equal to 0.0005
        of the sum of the Class YHH and Class ZHH Principal Balances in each case after
        giving effect to allocations of Realized Losses and distributions to be made through
        the end of the Distribution Date to which such provisions relate; and
3.      Making the larger of (a) the fraction whose numerator is (Y52 - ΔY52 ) and whose
        denominator is the sum of (Y52 - ΔY52) and (Z52 - ΔZ52) and (b) the
        fraction whose numerator is (Y51 - ΔY51) and whose denominator is the sum of
        (Y51 - ΔY51) and (Z51 - ΔZ51) as large as possible while remaining less
        than or equal to 0.0005.

In the event of a failure of the foregoing portion of the  definition of ClassY Principal
Reduction Amount to accomplish both of goals 1 and 2 above, the amounts thereof should be
adjusted to so as to accomplish such goals within the requirement that each REMIC I Y
Principal Reduction Amount must be less than or equal to the sum of (a) the Principal
Realized Losses to be allocated on the related Distribution Date for the related Pool
remaining after the allocation of such Realized Losses to the related class of ratio-strip
principal only certificates, if any, and (b) the remainder of the Available Distribution
Amount for the related Pool or after reduction thereof by the distributions to be made on
such Distribution Date (i) to the related class of ratio-strip principal only certificates,
if any, (ii) to the related class of ratio-strip interest only certificates, if any, and
(iii) in respect of interest on the related Class Y and Class Z Certificates, or, if both of
such goals cannot be accomplished within such requirement, such adjustment as is necessary
shall be made to accomplish goal 1 within such requirement.  In the event of any conflict
among the provisions of the definition of the REMIC I Y Principal Reduction Amounts, such
conflict shall be resolved on the basis of the goals and their priorities set forth above
within the requirement set forth in the preceding sentence.  If the formula allocations of
ΔY51 among ΔYj, ΔYk and ΔYl or ΔY52 among ΔYm, ΔYn,
ΔYo, ΔYp and ΔYq cannot be achieved because one or more of ΔYj, ΔYk,
ΔYl, ΔYm, ΔYn, ΔYo, ΔYp and ΔYq, as so defined is greater than
the related one of  ΔPj, ΔPk, ΔPl, ΔPm, ΔPn, ΔPo, ΔPp and
ΔPq, such an allocation shall be made as close as possible to the formula allocation
within the requirement that ΔYj < ΔPj, ΔYk < ΔPk, ΔYl < ΔPl,
ΔYm < ΔPm, ΔYn < ΔPn, ΔYo < ΔPo, ΔYp < ΔPp and
ΔYq < ΔPq.

The purpose of the foregoing definitional provisions together with the related provisions
allocating Realized Losses and defining the Class Y and Class Z Principal Distribution
Amounts is to accomplish the following goals in the following order of priority:

1.      Making the ratio of (Y62 - ΔY62 ) to (Y61 - ΔY61 ) equal to γ6 after
        taking account of the allocation Realized Losses and the distributions that will be
        made through the end of the Distribution Date to which such provisions relate and
        assuring that the Principal Reduction Amount for each of the Class YAA, Class YBB,
        Class YCC, Class YDD, Class YEE, Class YFF, Class YGG, Class YHH, Class ZAA, Class
        ZBB, Class ZCC, Class ZDD, Class ZEE, Class ZFF, Class ZGG and Class ZHH Certificates
        is greater than or equal to zero for such Distribution Date;
2.      Making the Class YAA Principal Balance less than or equal to 0.0005 of the sum of the
        Class YAA and Class ZAA Principal Balances, the Class YBB Principal Balance less than
        or equal to 0.0005 of the sum of the Class YBB and Class ZBB Principal Balances, the
        Class YCC Principal Balance less than or equal to 0.0005 of the sum of the Class YCC
        and Class ZCC Principal Balances, the Class YDD Principal Balance less than or equal
        to 0.0005 of the sum of the Class YDD and Class ZDD Principal Balances, the Class YEE
        Principal Balance less than or equal to 0.0005 of the sum of the Class YEE and Class
        ZEE Principal Balances, the Class YFF Principal Balance less than or equal to 0.0005
        of the sum of the Class YFF and Class ZFF Principal Balances, the Class YGG Principal
        Balance less than or equal to 0.0005 of the sum of the Class YGG and Class ZGG
        Principal Balances and the Class YHH Principal Balance less than or equal to 0.0005
        of the sum of the Class YHH and Class ZHH Principal Balances in each case after
        giving effect to allocations of Realized Losses and distributions to be made through
        the end of the Distribution Date to which such provisions relate; and
3.      Making the larger of (a) the fraction whose numerator is (Y62 - ΔY62 ) and whose
        denominator is the sum of (Y62 - ΔY62) and (Z62 - ΔZ62) and (b) the
        fraction whose numerator is (Y61 - ΔY61) and whose denominator is the sum of
        (Y61 - ΔY61) and (Z61 - ΔZ61) as large as possible while remaining less
        than or equal to 0.0005.

In the event of a failure of the foregoing portion of the  definition of ClassY Principal
Reduction Amount to accomplish both of goals 1 and 2 above, the amounts thereof should be
adjusted to so as to accomplish such goals within the requirement that each REMIC I Y
Principal Reduction Amount must be less than or equal to the sum of (a) the Principal
Realized Losses to be allocated on the related Distribution Date for the related Pool
remaining after the allocation of such Realized Losses to the related class of ratio-strip
principal only certificates, if any, and (b) the remainder of the Available Distribution
Amount for the related Pool or after reduction thereof by the distributions to be made on
such Distribution Date (i) to the related class of ratio-strip principal only certificates,
if any, (ii) to the related class of ratio-strip interest only certificates, if any, and
(iii) in respect of interest on the related Class Y and Class Z Certificates, or, if both of
such goals cannot be accomplished within such requirement, such adjustment as is necessary
shall be made to accomplish goal 1 within such requirement.  In the event of any conflict
among the provisions of the definition of the REMIC I Y Principal Reduction Amounts, such
conflict shall be resolved on the basis of the goals and their priorities set forth above
within the requirement set forth in the preceding sentence.  If the formula allocations of
ΔY61 among ΔYj and ΔYk or ΔY62 among ΔYl, ΔYm, ΔYn,
ΔYo, ΔYp and ΔYq cannot be achieved because one or more of ΔYj, ΔYk,
ΔYl, ΔYm, ΔYn, ΔYo, ΔYp and ΔYq, as so defined is greater than
the related one of  ΔPj, ΔPk, ΔPl, ΔPm, ΔPn, ΔPo, ΔPp and
ΔPq, such an allocation shall be made as close as possible to the formula allocation
within the requirement that ΔYj < ΔPj, ΔYk < ΔPk, ΔYl < ΔPl,
ΔYm < ΔPm, ΔYn < ΔPn, ΔYo < ΔPo, ΔYp < ΔPp and
ΔYq < ΔPq.

The purpose of the foregoing definitional provisions together with the related provisions
allocating Realized Losses and defining the Class Y and Class Z Principal Distribution
Amounts is to accomplish the following goals in the following order of priority:

1.      Making the ratio of (Y72 - ΔY72 ) to (Yj - ΔYj ) equal to γ7 after
        taking account of the allocation Realized Losses and the distributions that will be
        made through the end of the Distribution Date to which such provisions relate and
        assuring that the Principal Reduction Amount for each of the Class YAA, Class YBB,
        Class YCC, Class YDD, Class YEE, Class YFF, Class YGG, Class YHH, Class ZAA, Class
        ZBB, Class ZCC, Class ZDD, Class ZEE, Class ZFF, Class ZGG and Class ZHH Certificates
        is greater than or equal to zero for such Distribution Date;
2.      Making the Class YAA Principal Balance less than or equal to 0.0005 of the sum of the
        Class YAA and Class ZAA Principal Balances, the Class YBB Principal Balance less than
        or equal to 0.0005 of the sum of the Class YBB and Class ZBB Principal Balances, the
        Class YCC Principal Balance less than or equal to 0.0005 of the sum of the Class YCC
        and Class ZCC Principal Balances, the Class YDD Principal Balance less than or equal
        to 0.0005 of the sum of the Class YDD and Class ZDD Principal Balances, the Class YEE
        Principal Balance less than or equal to 0.0005 of the sum of the Class YEE and Class
        ZEE Principal Balances, the Class YFF Principal Balance less than or equal to 0.0005
        of the sum of the Class YFF and Class ZFF Principal Balances, the Class YGG Principal
        Balance less than or equal to 0.0005 of the sum of the Class YGG and Class ZGG
        Principal Balances and the Class YHH Principal Balance less than or equal to 0.0005
        of the sum of the Class YHH and Class ZHH Principal Balances in each case after
        giving effect to allocations of Realized Losses and distributions to be made through
        the end of the Distribution Date to which such provisions relate; and
3.      Making the larger of (a) the fraction whose numerator is (Y72 - ΔY72 ) and whose
        denominator is the sum of (Y72 - ΔY72) and (Z72 - ΔZ72) and (b) the
        fraction whose numerator is (Yj - ΔYj) and whose denominator is the sum of (Yj -
        ΔYj) and (Zj - ΔZj) as large as possible while remaining less than or equal
        to 0.0005.

In the event of a failure of the foregoing portion of the  definition of ClassY Principal
Reduction Amount to accomplish both of goals 1 and 2 above, the amounts thereof should be
adjusted to so as to accomplish such goals within the requirement that each REMIC I Y
Principal Reduction Amount must be less than or equal to the sum of (a) the Principal
Realized Losses to be allocated on the related Distribution Date for the related Pool
remaining after the allocation of such Realized Losses to the related class of ratio-strip
principal only certificates, if any, and (b) the remainder of the Available Distribution
Amount for the related Pool or after reduction thereof by the distributions to be made on
such Distribution Date (i) to the related class of ratio-strip principal only certificates,
if any, (ii) to the related class of ratio-strip interest only certificates, if any, and
(iii) in respect of interest on the related Class Y and Class Z Certificates, or, if both of
such goals cannot be accomplished within such requirement, such adjustment as is necessary
shall be made to accomplish goal 1 within such requirement.  In the event of any conflict
among the provisions of the definition of the REMIC I Y Principal Reduction Amounts, such
conflict shall be resolved on the basis of the goals and their priorities set forth above
within the requirement set forth in the preceding sentence.  If the formula allocation of
ΔY72 among ΔYk, ΔYl, ΔYm, ΔYn, ΔYo, ΔYp and ΔYq
cannot be achieved because one or more of ΔYk, ΔYl, ΔYm, ΔYn, ΔYo,
ΔYp and ΔYq, as so defined is greater than the related one of ΔPk, ΔPl,
ΔPm, ΔPn, ΔPo, ΔPp and ΔPq, such an allocation shall be made as
close as possible to the formula allocation within the requirement that ΔYk < ΔPk,
ΔYl < ΔPl, ΔYm < ΔPm, ΔYn < ΔPn, ΔYo < ΔPo, ΔYp
> ΔPp and ΔYq < ΔPq.





[Method of calculating initial balance of the Class Y and Class Z interest to come]

NOTES:

1.      Classes YAA and ZAA are related to the Group AA loans.  The sum of the Class
Principal Balances for the Class YAA and Class ZAA Certificates is equal to the aggregate
stated principal balance of the Group AA Loans [minus the Class Principal Balance of the
Class AA-P Certificates].  Classes YCC and ZCC are related to the Group CC loans.  The sum
of the Class Principal Balances for the Class YCC and Class ZCC Certificates is equal to the
aggregate stated principal balance of the Group CC Loans [minus the Class Principal Balance
of the Class CC-P Certificates].  Classes YBB and ZBB are related to the Group BB loans.
The sum of the Class Principal Balances for the Class YBB and Class ZBB Certificates is
equal to the aggregate stated principal balance of the Group BB Loans [minus the Class
Principal Balance of the Class BB-P Certificates].  The Y and Z classes will be principal
and interest classes bearing interest at the pass-through rate for the related loan group.

2.      The Class CB pass-through rate is the weighted average of the pass-through rates on
the Class YAA, Class YCC and Class YBB Certificates.
