payment has not been received by the close of business on the corresponding day
of the month immediately succeeding the month in which such payment was first
due, or, if there is not such corresponding day (e.g., as when a 30-day month
follows a 31-day month in which a payment was due on the 31st day of such

Delinquent" and the third immediately succeeding month.

as of the first calendar day of the month in which such Effective Date occurs,
without giving effect to any grace period permitted by the related Mortgage Note
or for which the Servicer has accepted a deed in lieu of foreclosure. No
Securitized Loan shall be considered delinquent for the purpose of this
definition by virtue of the related Mortgagor having made payment to the prior
servicer.

Business Day, the next succeeding Business Day).

     Due Date: The day of the calendar month on which the Monthly Payment is due

Date and ending on the first day of the month of the Remittance Date.

shall be an Eligible Investment if such instrument evidences either (i) a right
to receive only interest payments with respect to the obligations underlying
such instrument, or (ii) both principal and interest payments derived from
obligations underlying such instrument and the principal and interest payments
with respect to such instrument provide a yield to maturity of greater than 120%

and authority, acting alone, to do any and all things in connection with such
servicing and administration which the Servicer may deem necessary or desirable,
consistent with the terms of this Agreement and with Accepted Servicing
Practices. The Servicer may designate the sub-servicer to perform the
obligations hereunder, provided that such designation shall not relieve the
Servicer of such obligations.

     The Seller and the Servicer additionally agree as follows:

          (a) The Servicer shall (A) record or cause to be recorded the Mortgage
or the Assignment of Mortgage, as applicable, with respect to all MERS Eligible
Securitized Loans, in the name of MERS, or shall ascertain that such have
previously been so recorded; (B) prepare or cause to be prepared all Assignments
of Mortgage with respect to all Non-MERS Eligible Securitized Loans; (C) prepare
for recording or cause to be recorded, subject to Section 2.03(b) hereof, all
Assignments of Mortgage with respect to Non-MERS Securitized Loans in the name
of the related Trust; (D) pay the recording costs pursuant to Section 2.03
hereof; and/or (E) track such Mortgages and Assignments of Mortgage to ensure
they have been recorded. The Servicer shall be entitled to be paid by the Seller
its out-of-pocket costs for the preparation and recordation of the Mortgages and
Assignments of Mortgage. After the expenses of such recording costs pursuant to
Section 2.03 hereof shall have been paid by the Servicer, the Servicer shall
submit to the Seller a reasonably detailed invoice for reimbursement of
recording costs it incurred hereunder.

          (b) If applicable, the Servicer shall, in accordance with the relevant
provisions of the Cranston-Gonzales National Affordable Housing Act of 1990, as
the same may be amended from time to time, and the regulations provided in
accordance with the Real Estate Settlement Procedures Act, provide notice to the
Mortgagor of each Securitized Loan of the transfer of the servicing thereto to
the Servicer.

          (c) The Servicer shall be responsible for the preparation of and costs
associated with notifications to Mortgagors of the assumption of servicing by
the Servicer.

     Consistent with the terms of this Agreement and except as provided in
Section 3.15 hereof, the Servicer may waive any late payment charge, assumption
fee or other fee (other than a Prepayment Charge) that may be collected in the
ordinary course of servicing the Securitized Loans. The Servicer shall not make
any future advances to any Mortgagor under any Securitized


                                      -16-

Loan, and (unless the Mortgagor is in default with respect to the Securitized
Loan or such default is, in the judgment of the Servicer, reasonably
foreseeable) the Servicer shall not permit any modification of any material term
of any Securitized Loan, including any modification that would change the
Mortgage Interest Rate, defer or forgive the payment of principal or interest,
reduce or increase the outstanding principal balance (except for actual payments
of principal) or change the final maturity date on such Securitized Loan. In the
event of any such modification which permits the deferral of interest or
principal payments on any Securitized Loan, the Servicer shall, on the Business
Day immediately preceding the Remittance Date in any month in which any such
principal or interest payment has been deferred, make a Monthly Advance in
accordance with Section 4.03, in an amount equal to the difference between (a)
such month's principal and one month's interest at the Securitized Loan
Remittance Rate on the unpaid principal balance of such Securitized Loan and (b)
the amount paid by the Mortgagor. The Servicer shall be entitled to
reimbursement for such advances to the same extent as for all other advances
made pursuant to Section 4.03. The Servicer may permit modifications to a
Securitized Loan which are authorized by the express terms of either an allonge
to the related Mortgage Note or an addendum to the related Mortgage in existence
as of the Effective Date. If TMHL wishes to make a modification to a Securitized
Loan which is not permitted under this Section 3.01, then TMHL must repurchase
such Securitized Loan from the related Trust on the terms and conditions
provided in the Trust Agreement. Without limiting the generality of the
foregoing, the Servicer shall continue, and is hereby authorized and empowered,
to execute and deliver on behalf of itself and the related Trust, all
instruments of satisfaction or cancellation, or of partial or full release,
discharge and all other comparable instruments, with respect to the Securitized
Loans and with respect to the Mortgaged Properties. Upon the written request of
the Servicer, the Trustee shall execute and deliver to the Servicer, within the
later of fifteen days from the Closing Date or within fifteen days of such
Servicer request, any powers of attorney (one for each county in which any of
the Mortgaged Properties are located) and other documents, furnished to it by
the Servicer and reasonably satisfactory to the Trustee, necessary or
appropriate to enable the Servicer to carry out its servicing and administrative
duties under this Agreement.

     Section 3.02 Collection of Securitized Loan Payments.

     Continuously from the Closing Date until the date each Securitized Loan
ceases to be subject to this Agreement, the Servicer shall proceed diligently to
collect all payments due under each of the Securitized Loans when the same shall
become due and payable and shall take special care in ascertaining and
estimating Escrow Payments and all other charges that will become due and
payable with respect to the Securitized Loans and each related Mortgaged
Property, to the end that the installments payable by the Mortgagors will be
sufficient to pay such charges as and when they become due and payable.

     Section 3.03 Establishment of and Deposits to Custodial Account.

          (a) The Servicer shall segregate and hold all funds collected and
received pursuant to the Securitized Loans separate and apart from any of its

Account, in the form of a time deposit or demand account, titled "Thornburg
Mortgage Home Loans, Inc. in trust for one or more Thornburg


                                      -17-

Mortgage Securities Trusts." The Custodial Account shall be established with a
Qualified Depository. Any funds deposited in the Custodial Account may be
invested in Eligible Investments subject to the provisions of Section 3.11
hereof. Funds deposited in the Custodial Account may be drawn on by the Servicer
in accordance with Section 3.04 hereof. The creation of the Custodial Account
shall be evidenced by a letter agreement in the form of Exhibit B. A copy of
such certification or letter agreement shall be furnished to each Trustee and
the Master Servicer.

          (b) The Servicer shall deposit in the Custodial Account on a daily
basis, and retain therein, the following collections received by the Servicer

               (v) all Insurance Proceeds (other than any amounts immediately

               (vi) all Condemnation Proceeds that are not applied to the

connection with the deductible clause in any blanket hazard insurance policy;

               (x) any amounts received with respect to or related to any REO
Property or REO Disposition Proceeds;

               (xi) any amounts required to be deposited pursuant to Section
3.11 in connection with any losses realized on Eligible Investments with respect
to funds held in the Custodial Account;


                                      -18-

               (xii) any amounts required to be deposited by the Servicer
pursuant to Section 3.16(a) in connection with any unpaid claims that are a
result of a breach by the Servicer or any sub-servicer of its obligations
hereunder or under a PMI Policy;

               (xiii) any amounts received by it under any PMI Policy; and

               (xiv) any other amount required hereunder to be deposited by the
Servicer in the Custodial Account.

     The foregoing requirements for deposit into the Custodial Account shall be
exclusive, it being understood and agreed that, without limiting the generality
of the foregoing, payments in the nature of (i) late payment charges, penalty
interest and insufficient fund charges, (ii) assumption and modification fees,
(iii) other Ancillary Income and (iv) the Servicing Fee need not be deposited by
the Servicer into the Custodial Account.

     Any interest paid on funds deposited in the Custodial Account by the
depository institution shall accrue to the benefit of the Servicer as additional
servicing compensation and the Servicer shall be entitled to retain and withdraw
such interest from the Custodial Account pursuant to Section 3.04 of this
Agreement. Additionally, any other benefit derived from the Custodial Account
associated with the receipt, disbursement and accumulation of principal,
interest, taxes, hazard insurance, mortgage insurance, etc. shall accrue for the
benefit of the Servicer.

     Section 3.04 Permitted Withdrawals From Custodial Account.

     The Servicer shall, from time to time, withdraw funds from the Custodial
Account for the following purposes:

               (i) to make payments to the Master Servicer in the amounts and in
the manner provided for in Section 4.01;

               (ii) in the event the Servicer has elected not to retain the
Servicing Fee out of any Mortgagor payments on account of interest or other
recovery of interest with respect to a particular Securitized Loan (including
late collections of interest on such Securitized Loan, or interest portions of
Insurance Proceeds, Liquidation Proceeds or Condemnation Proceeds) prior to the
deposit of such Mortgagor payment or recovery in the Custodial Account, to pay
to itself the related Servicing Fee from all such Mortgagor payments on account
of interest or other such recovery for interest with respect to that Securitized
Loan;

               (iii) to pay itself investment earnings on funds deposited in the
Custodial Account;

               (iv) to transfer funds to another Qualified Depository in
accordance with Section 3.11 hereof;

               (v) to invest funds in certain Eligible Investments in accordance
with Section 3.11 hereof;


                                      -19-

               (vi) to reimburse itself to the extent of funds held in the
Custodial Account for Monthly Advances of the Servicer's funds made pursuant to
Section 4.03. The Servicer's right to reimburse itself pursuant to this
subclause (vi) with respect to any Securitized Loan shall be limited to amounts
received on or in respect of the related Securitized Loan which represent late
recoveries of payments of principal or interest with respect to which a Monthly
Advance was made, it being understood that in the case of any such reimbursement
the Servicer's right thereto shall be prior to the rights of the related Trust;
provided, however, that following the final liquidation of a Securitized Loan,
the Servicer may reimburse itself for previously unreimbursed Monthly Advances
in excess of Liquidation Proceeds or Insurance Proceeds with respect to such
Securitized Loan from any funds in the Custodial Account relating to Securitized
Loans in the same Trust, it being understood, in the case of any such
reimbursement, that the Servicer's right thereto shall be prior to the rights of
the related Trust. The Servicer may recover at any time from amounts on deposit
in the Custodial Account with respect to Securitized Loans in the same Trust the
amount of any Monthly Advances that the Servicer deems nonrecoverable or that
remain unreimbursed to the Servicer from related Liquidation Proceeds after the
final liquidation of the related Securitized Loan. In addition, the Servicer
may, at any time, withdraw from the Custodial Account funds that are held for
future distribution (i.e., were not included in the principal and interest for
the preceding Distribution Date) to reimburse itself for Monthly Advances
previously made by the Servicer;

               (vii) to reimburse itself for unreimbursed Servicing Advances,
and for any unpaid Servicing Fees, the Servicer's right to reimburse itself
pursuant to this subclause (vii) with respect to any Securitized Loan being
limited to related Liquidation Proceeds, Condemnation Proceeds, Insurance
Proceeds, REO Disposition Proceeds and other amounts received in respect of the
related REO Property, and such other amounts as may be collected by the Servicer
from the Mortgagor or otherwise relating to the Securitized Loan, it being
understood that, in the case of any such reimbursement, the Servicer's right
thereto shall be prior to the rights of the related Trust;

               (viii) to reimburse the Servicer for expenses incurred by, and
reimbursable to, the Servicer pursuant to Section 6.03, but only to extent such
amounts are determined to be reimbursable by the related Trust pursuant to
Section 6.03;

               (ix) to reimburse itself for expenses incurred or reimbursable to
the Servicer pursuant to Section 3.12 from funds with respect to Securitized
Loans in the same Trust to the extent not previously reimbursed under clause
(vii) of this Section 3.04;

               (x) to withdraw funds with respect to Securitized Loans in the
same Trust necessary for the operation, management and maintenance of any REO
related property to the extent not previously reimbursed under clause (vii) of
this Section 3.04;

               (xi) to withdraw any funds deposited to the Custodial Account in
error; and,

               (xii) to clear and terminate the Custodial Account upon the
termination of this Agreement;


                                      -20-

     Notwithstanding the foregoing clauses (vi) and (vii), no Monthly Advances
or Servicing Advances shall be required to be made by the Servicer if such
Monthly Advance or Servicing Advance would, if made, be, in the Servicer's
reasonable judgment, nonrecoverable. The determination by the Servicer that it
has made a nonrecoverable Monthly Advance or Servicing Advance, or that any
proposed Monthly Advance or Servicing Advance would be a nonrecoverable advance,
shall be evidenced by an Officer's Certificate of the Servicer delivered to the
Master Servicer.

     Section 3.05 Establishment of and Deposits to Escrow Account.

     The Servicer shall segregate and hold all funds collected and received
pursuant to a Securitized Loan constituting Escrow Payments separate and apart
from any of its own funds and general assets and shall establish and maintain an
Escrow Account, in the form of a time deposit or demand account, titled
"Thornburg Mortgage Home Loans, Inc. in trust for one or more Thornburg Mortgage
Securities Trusts." The Escrow Account shall be established with a Qualified
Depository in a manner that shall provide maximum available insurance
thereunder. Funds deposited in the Escrow Account may be drawn on by the
Servicer in accordance with Section 3.06. The creation of the Escrow Account
shall be evidenced by a letter agreement in the form of Exhibit C. A copy of
such certification or letter agreement shall be furnished to each Trustee and
the Master Servicer.

     The Servicer shall deposit in the Escrow Account or Accounts on a daily
basis, and retain therein:

          (i) all Escrow Payments collected on account of the Securitized Loans,
for the purpose of effecting timely payment of any such items as required under
the terms of this Agreement; and

          (ii) all amounts representing Insurance Proceeds or Condemnation
Proceeds that are to be applied to the restoration or repair of any Mortgaged
Property.

     The Servicer shall make withdrawals from the Escrow Account only to effect
such payments as are required under this Agreement, as set forth in Section
3.06. The Servicer shall retain any interest paid on funds deposited in the
Escrow Account by the depository institution, other than interest on escrowed
funds required by law to be paid to the related Mortgagor. Additionally, any
other benefit derived from the Escrow Account associated with the receipt,
disbursement and accumulation of principal, interest, taxes, hazard insurance,
mortgage insurance, etc. shall accrue to the Servicer. To the extent required by
law, the Servicer shall pay interest on escrowed funds to the related Mortgagor
notwithstanding that the Escrow Account may be non-interest bearing or that
interest paid thereon is insufficient for such purposes.

     Section 3.06 Permitted Withdrawals From Escrow Account.

     Withdrawals from the Escrow Account or Accounts may be made by the Servicer
only:


                                      -21-

          (i) to effect payments of ground rents, taxes, assessments, water
rates, sewer rents, mortgage insurance premiums, condominium charges, fire and
hazard insurance premiums or other items constituting Escrow Payments for the
related Mortgage;

          (ii) to refund to any related Mortgagor any funds found to be in
excess of the amounts required under the terms of the related Securitized Loan;

          (iii) as permitted by applicable state law, for transfer to the
Custodial Account and application to reduce the principal balance of the related
Securitized Loan in accordance with the terms of the related Mortgage and
Mortgage Note;

          (iv) for application to restore or repair the related Mortgaged
Property in accordance with the Master Servicing Guide;

          (v) to pay to the Servicer, or the related Mortgagor to the extent
required by law, any interest paid on the funds with respect to a Securitized
Loan deposited in the Escrow Account; and

          (vi) to reimburse itself for any Servicing Advances made with respect
to Escrow Payments for a Securitized Loan or the related Mortgaged Properties,
but only from amounts received on the related Securitized Loan which represent
late collections of Escrow Payments thereunder;

          (vii) to withdraw any funds deposited into the Escrow Account in
error; and

          (viii) to clear and terminate the Escrow Account on the termination of
this Agreement.

     The Servicer will be responsible for the administration of the Escrow
Accounts and will be obligated to make Servicing Advances to the Escrow Account
in respect of its obligations under this Section 3.06, reimbursable from the
Escrow Accounts or Custodial Account to the extent not collected from a
Mortgagor, anything to the contrary notwithstanding, when and as necessary to
avoid the lapse of insurance coverage on the related Mortgaged Property, or
which the Servicer knows, or in the exercise of the required standard of care of
the Servicer hereunder should know, is necessary to avoid the loss of such
Mortgaged Property due to a tax sale or the foreclosure as a result of a tax
lien. If any such payment has not been made and the Servicer receives notice of
a tax lien with respect to such Mortgaged Property being imposed, the Servicer
will, within ten (10) Business Days of such notice, advance or cause to be
advanced funds necessary to discharge such lien on such Mortgaged Property.

     Section 3.07 Restoration of Mortgaged Property.

     The Servicer need not obtain the approval of the Master Servicer prior to
releasing any Insurance Proceeds or Condemnation Proceeds to the 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, with
respect to claims of $10,000 or more, the Servicer shall


                                      -22-

comply with the following conditions in connection with any such release of
Insurance Proceeds or Condemnation Proceeds:

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

          (ii) the 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.

          (iii) the Servicer shall verify that the Securitized Loan is not 60 or
more days delinquent; and

          (iv) pending repairs or restoration, the Servicer shall place the
Insurance Proceeds or Condemnation Proceeds in the Escrow Account.

          With respect to claims of less than $10,000, the Servicer shall comply
with the following conditions in connection with any such release of Insurance
Proceeds or Condemnation Proceeds:

          (v) the related Mortgagor shall provide an affidavit verifying the
completion of repairs and issuance of any required approvals with respect
thereto;

          (vi) the Servicer shall verify the total amount of the claim with the
applicable insurance company; and

          (vii) pending repairs or restoration, the Servicer shall place the
Insurance Proceeds or Condemnation Proceeds in the Escrow Account.

     If the Trustee is named as an additional loss payee, the Servicer is hereby
empowered to endorse any loss draft issued in respect of such a claim in the
name of the related Trust.

     Section 3.08 Fidelity Bond and Errors and Omissions Insurance.

     The Servicer shall keep in force and shall cause each sub-servicer to keep
in force during the term of this Agreement a Fidelity Bond and Errors and
Omissions Insurance the minimum coverage of which shall be at least equal to the
coverage required by the Master Servicer in the Master Servicing Guide (unless a
waiver of such requirement has been obtained by the Servicer from the Master
Servicer). Such Fidelity Bond and Errors and Omissions Insurance shall be
maintained with recognized insurers, shall be in such form and amount as would
permit the Servicer to be qualified with the Master Servicer as a servicer, and
shall by its terms not be cancelable without thirty days' prior written notice
to the Trustee and the Master Servicer. The Servicer and each sub-servicer shall
be deemed to have complied with this provision if an affiliate of the Servicer
has such errors and omissions and fidelity bond coverage and, by the terms of
such insurance policy or fidelity bond, the coverage afforded thereunder extends
to the Servicer. The Servicer shall furnish and shall cause each sub-servicer to
furnish to the Trustee and the Master Servicer a copy of each such bond and
insurance policy upon their request.


                                      -23-

     Section 3.09 Notification of Adjustments.

     With respect to each Adjustable Rate Securitized Loan, the Servicer shall
adjust the Mortgage Interest Rate on the related interest rate adjustment date
and shall adjust the Monthly Payment on the related mortgage payment adjustment
date, if applicable, in compliance with the requirements of applicable law and
the related Mortgage and Mortgage Note. The 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 Interest Rate and
Monthly Payment adjustments. The Servicer shall promptly, upon written request
therefor, deliver to the Master Servicer such notifications and any additional
applicable data regarding such adjustments and the methods used to calculate and
implement such adjustments. Upon the discovery by the Servicer or the receipt of
notice from the Master Servicer that the Servicer has failed to adjust a
Mortgage Interest Rate or Monthly Payment in accordance with the terms of the
related Mortgage Note, the Servicer shall immediately deposit in the Custodial
Account from its own funds the amount of any interest loss or deferral caused
thereby.

     Section 3.10 Payment of Taxes, Insurance and Other Charges. With respect to
each Securitized Loan, the Servicer shall maintain accurate records reflecting
the status of ground rents, taxes, assessments, water rates and other charges
which are or may become a lien upon the Mortgaged Property and the status of
fire and hazard insurance coverage and shall obtain, from time to time, all
bills for the payment of such charges (including renewal premiums) and shall
effect payment thereof prior to the applicable penalty or termination date and
at a time appropriate for securing maximum discounts allowable, employing for
such purpose deposits of the Mortgagor in the Escrow Account which shall have
been estimated and accumulated by the Servicer in amounts sufficient for such
purposes, as allowed under the terms of the Mortgage or applicable regulations.
The Servicer assumes full responsibility for the payment of all such bills and
shall effect payments of all such bills irrespective of the Mortgagor's faithful
performance in the payment of same or the making of the Escrow Payments and
shall make advances from its own funds to effect such payments. The Servicer
shall employ Accepted Servicing Practices to ensure that the related Mortgaged
Property is not subjected to a tax lien as a result of nonpayment and that such
Mortgaged Property is not left uninsured.

     Section 3.11 Protection of Accounts.

     The Servicer may transfer the Custodial Account or the Escrow Account to a
different Qualified Depository from time to time. The Servicer shall give
written notice to the Trustee and the Master Servicer of the location of the
Custodial Account maintained by it with respect to the Securitized Loans when
established and prior to any change thereof.

     The Servicer shall bear any expenses, losses or damages sustained by the
Trustee or the Master Servicer if the Custodial Account and/or the Escrow
Account are not demand deposit accounts.

     Amounts on deposit in the Custodial Account and the Escrow Account may at
the option of the Servicer be invested in Eligible Investments; provided that in
the event that amounts on deposit in the Custodial Account or the Escrow Account
exceed the amount fully insured by the FDIC (the "Insured Amount"), the Servicer
shall be obligated to invest the excess amount over


                                      -24-

the Insured Amount in Eligible Investments on the same Business Day as such
excess amount becomes present in the Custodial Account or the Escrow Account.
Any such Eligible Investment shall mature no later than the Business Day
immediately preceding the related Remittance Date or other date on which funds
are needed to be disbursed. Any such Eligible Investment shall be made in the
name of the Servicer in trust for the benefit of one or more Thornburg Mortgage
Securities Trusts, as their interests may appear. All income on or gain realized
from any such Eligible Investment shall be for the benefit of the Servicer and
may be withdrawn at any time by the Servicer. Any losses incurred in respect of
any such investment shall be deposited in the Custodial Account or the Escrow
Account by the Servicer out of its own funds immediately as realized.

     Section 3.12 Title, Management and Disposition of REO Property.

     In the event that title to any Mortgaged Property is acquired in
foreclosure or by deed in lieu of foreclosure, the deed or certificate of sale
shall be taken in the name of the related Trust, or in the event the related
Trust is not authorized or permitted to hold title to real property in the state
where the REO Property is located, or would be adversely affected under the
"doing business" or tax laws of such state by so holding title, the deed or
certificate of sale shall be taken in the name of such Person or Persons as
shall be consistent with an Opinion of Counsel obtained by the Servicer from any
attorney duly licensed to practice law in the state where the REO Property is
located. The Person or Persons holding such title other than the related Trust
shall acknowledge in writing that such title is being held as nominee for the
related Trust.

     The Servicer shall manage, conserve, protect and operate each REO Property
for the related Trust solely for the purpose of its prompt disposition and sale.
The Servicer, either itself or through an agent selected by the Servicer, shall
manage, conserve, protect and operate such 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. The Servicer shall attempt to sell the same (and
may temporarily rent the same for a period not greater than one year, except as
otherwise provided below) on such terms and conditions as the Servicer deems to
be in the best interest of the related Trust.

     Notwithstanding anything to the contrary contained in this Section 3.12, in
connection with a foreclosure or acceptance of a deed in lieu of foreclosure, in
the event the Servicer has reasonable cause to believe that a Mortgaged Property
is contaminated by hazardous or toxic substances or wastes, or if the Master
Servicer otherwise requests, an environmental inspection or review of such
Mortgaged Property to be conducted by a qualified inspector shall be arranged by
the Servicer. Upon completion of the inspection, the Servicer shall provide the
Master Servicer with a written report of such environmental inspection. In the
event that the environmental inspection report indicates that the Mortgaged
Property is contaminated by hazardous or toxic substances or wastes, the
Servicer shall not proceed with foreclosure or acceptance of a deed in lieu of
foreclosure. In the event that the environmental inspection report is
inconclusive as to the whether or not the Mortgaged Property is contaminated by
hazardous or toxic substances or wastes, the Servicer shall not, without the
prior written approval of the Master Servicer, proceed with foreclosure or
acceptance of a deed in lieu of foreclosure. The


                                      -25-

Servicer shall be reimbursed for all Servicing Advances made pursuant to this
paragraph with respect to the related Mortgaged Property from the amounts on
deposit in the Custodial Account with respect to Securitized Loans in the same
Trust.

     In the event that a Trust which has made one or more REMIC elections
acquires any REO Property in connection with a default or imminent default on a
Securitized Loan, the Servicer shall dispose of such REO Property not later than
the end of the third taxable year after the year of its acquisition by the
related Trust unless the Servicer has applied for and received a grant of
extension from the Internal Revenue Service (and provides a copy of the same to
the Master Servicer) to the effect that, under the REMIC Provisions and any
relevant proposed legislation and under applicable state law, a REMIC elected by
such Trust may hold REO Property for a longer period without adversely affecting
the REMIC status of such REMIC or causing the imposition of a federal or state
tax upon such REMIC. If the Servicer has received such an extension (and
provided a copy of the same to the Master Servicer), then the Servicer shall
continue to attempt to sell the REO Property for its fair market value for such
period longer than three years as such extension permits (the "Extended
Period"). If the Servicer has not received such an extension, and the Servicer
is unable to sell the REO Property within the period ending 3 months before the
end of such third taxable year after its acquisition by the related Trust or if
the Servicer has received such an extension, and the Servicer is unable to sell
the REO Property within the period ending three months before the close of the
Extended Period, the Servicer shall, before the end of the three-year period or
the Extended Period, as applicable, (i) purchase such REO Property at a price
equal to the REO Property's fair market value or (ii) auction the REO Property
to the highest bidder (which may be the Servicer) in an auction reasonably
designed to produce a fair price prior to the expiration of the three-year
period or the Extended Period, as the case may be. The related Trustee shall
sign any document or take any other action reasonably requested by the Servicer
which would enable the Servicer, on behalf of the related Trust, to request such
grant of extension.

     Notwithstanding any other provisions of this Agreement, no REO Property
acquired by a Trust shall be rented (or allowed to continue to be rented) or
otherwise used by or on behalf of such Trust in such a manner or pursuant to any
terms that would: (i) cause such REO Property to fail to qualify as "foreclosure
property" within the meaning of Section 860G(a)(8) of the Code; or (ii) subject
any REMIC elected by such Trust to the imposition of any federal income taxes on
the income earned from such REO Property, including any taxes imposed by reason
of Sections 860F or 860G(c) of the Code, unless the Servicer has agreed to
indemnify and hold harmless such Trust with respect to the imposition of any
such taxes.

     The Servicer shall also maintain on each REO Property hazard insurance with
extended coverage in an amount which is at least equal to the lesser of (i) the
maximum insurable value of the improvements which are a part of such property
and (ii) the outstanding Principal Balance of the Securitized Loan at the time
it becomes REO Property, to the extent required and available under the Flood
Disaster Protection Act of 1973, as amended, flood insurance in the amount
required above.

     The disposition of REO Property shall be carried out by the Servicer at
such price, and upon such terms and conditions, as the Servicer deems to be in
the best interests of the related


                                      -26-

Trust. The proceeds of sale of the REO Property shall be promptly deposited in
the Custodial Account. After the expenses of such disposition shall have been
paid, the Servicer shall reimburse itself pursuant to Section 3.04 hereof for
any Servicing Advances it incurred with respect to such REO Property.

     The Servicer shall withdraw from the amounts on deposit in the Custodial
Account with respect to Securitized Loans in the same Trust funds necessary for
the proper operation, management and maintenance of the REO Property, including
the cost of maintaining any hazard insurance pursuant to the Master Servicing
Guide. The Servicer shall make monthly distributions on each Remittance Date to
the Trustee of the net cash flow from the REO Property (which shall equal the
revenues from such REO Property net of the expenses described in this Section
3.12 and of any reserves reasonably required from time to time to be maintained
to satisfy anticipated liabilities for such expenses).

     Section 3.13 Real Estate Owned Reports.

     Together with the statement furnished pursuant to Section 4.02, the
Servicer shall furnish by electronic transmission to the Master Servicer on or
before the Remittance Date each month a statement with respect to any REO
Property covering the operation of such REO Property for the previous month and
the 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
month. That statement shall be accompanied by such other information as the
Master Servicer shall reasonably request.

     Section 3.14 MERS.

          (a) The Servicer shall take such actions as are necessary to cause the
related Trust to be clearly identified as the owner of each MERS Securitized
Loan on the records of MERS for purposes of the system of recording transfers of
beneficial ownership of mortgages maintained by MERS.

          (b) The Servicer shall maintain in good standing its membership in
MERS. In addition, the Servicer shall comply with all rules, policies and
procedures of MERS, including the Rules of Membership, as amended, and the MERS
Procedures Manual, as amended.

          (c) With respect to all MERS Securitized Loans serviced hereunder, the
Servicer shall promptly notify MERS as to any transfer of beneficial ownership
or release of any security interest in such Securitized Loans.

          (d) With respect to all MERS Securitized Loans serviced hereunder, the
Servicer shall notify MERS as to any transfer of servicing pursuant to Section
9.01 within 10 Business Days of such transfer of servicing. The Servicer shall
cooperate with each Trustee and any successor servicer to the extent necessary
to ensure that such transfer of servicing is appropriately reflected on the MERS
system.


                                      -27-

     Section 3.15 Waiver of Prepayment Penalties.

     Except as provided below, the Servicer or any designee of the Servicer
shall not waive any Prepayment Charge with respect to any Securitized Loan. If
the Servicer or its designee fails to collect a Prepayment Charge at the time of
the related prepayment of any Securitized Loan subject to such Prepayment
Charge, the Servicer shall pay to the Trust at such time (by deposit to the
Custodial Account) an amount equal to the amount of the Prepayment Charge not
collected; provided, however, the Servicer shall not have any obligation to pay
the amount of any uncollected Prepayment Charge under this Section 3.15 if the
failure to collect such amount is the result of inaccurate or incomplete
information in the Prepayment Charge Schedule provided by the Seller and which
is included as part of the schedule of Securitized Loans attached to the related
Transfer Notice. The Seller warrants that the schedule of Prepayment Charges
listed in each Transfer Notice will be complete, true and accurate and may be
relied on by the Servicer in its calculation of Prepayment Charges. If the
Prepayment Charge data set forth in a Transfer Notice is incorrect, then the
Servicer shall have no liability for any loss resulting from calculation of
Prepayment Charges using the data provided by the Seller. Notwithstanding the
above, the Servicer or its designee may waive a Prepayment Charge without paying
to the related Trust the amount of such Prepayment Charge only if the related
prepayment is not the result of a refinancing by the Servicer or its designee
and such waiver (i) relates to a defaulted Securitized Loan or a reasonably
foreseeable default, such waiver is standard and customary in servicing similar
mortgage loans to the Securitized Loans, and such waiver, in the reasonable
judgment of the Servicer, would maximize recovery of total proceeds from the
Securitized Loan, taking into account the amount of such Prepayment Charge and
the related Securitized Loan, or (ii) relates to a prepayment charge the
collection of which, in the reasonable judgment of the Servicer, would be a
violation of applicable law.

     Section 3.16 Servicing and Administration of PMI Policies.

          (a) The Servicer shall take all such actions on behalf of the Trustee
as are necessary to service, maintain and administer PMI Policies and to perform
and enforce the rights under such Policies for the benefit of the related Trust.
Except as expressly set forth herein, the Servicer shall have full authority on
behalf of the related Trust to do anything it reasonably deems appropriate or
desirable in connection with the servicing, maintenance and administration of
the PMI Policies. The Servicer shall not take, or permit any sub-servicer to
modify or assume a Securitized Loan covered by a PMI Policy or take any other
action with respect to such Securitized Loan which would result in non-coverage
under any PMI Policy of any loss which, but for the actions of the Servicer or
the Sub-Servicer, would have been covered thereunder. If a PMI Insurer fails to
pay a claim under a PMI Policy as a result of breach by the Servicer or a
sub-servicer of its obligations hereunder or under a PMI Policy, the Servicer
shall be required to deposit in the Custodial Account on or prior to the next
succeeding Remittance Date an amount equal to such unpaid claim from its own
funds without any right to reimbursement from the related Trust. To the extent
coverage is available, the Servicer shall keep or cause to be kept in full force
and effect the Insurance Policies for as long as any Certificates issued by the
related Trust are outstanding. The Servicer shall cooperate with each PMI
Insurer and shall use its best efforts to furnish all reasonable aid, evidence
and information in the possession of the Servicer to which the Servicer has
access with respect to any Securitized Loan; provided, however,


                                      -28-

notwithstanding anything to the contrary contained in a PMI Policy, the Servicer
shall not be required to submit any reports to a PMI Insurer until a reporting
date that is at least 15 days after the Servicer has received sufficient loan
level information from the Seller to appropriately code its servicing system in
accordance with such PMI Insurer's requirements.

          (b) The Servicer shall deposit into the Custodial Account pursuant to
Section 3.03(xiii) hereof all Insurance Proceeds received from the PMI Insurer
under the terms of a PMI Policy.

          (c) Notwithstanding the provisions of (a) and (b) above, the Servicer
shall not take any action in regard to any PMI Policy inconsistent with the
interests of the related Trust or the related Certificateholders or with the
rights and interests of the related Trust or the related Certificateholders
under this Agreement.

          (d) The related Trustee shall furnish the Servicer with any powers of
attorney and other documents (within fifteen (15) days upon request from the
Servicer) in form as provided to it necessary or appropriate to enable the
Servicer to service and administer any PMI Policy; provided, however, that the
related Trustee shall not be liable for the actions of the Servicer under such
powers of attorney.

     Section 3.17 Maintenance of Hazard Insurance.

     The Servicer shall cause to be maintained for each Securitized Loan hazard
insurance such that all buildings upon the related Mortgaged Property are
insured by a generally acceptable insurer against loss by fire, hazards of
extended coverage and such other hazards as are customary in the area where such
Mortgaged Property is located in an amount which is at least equal to the lesser
of (i) the current principal balance of such Securitized Loan and (ii) the
amount necessary to fully compensate for any damage or loss to the improvements
that are a part of such property on a replacement cost basis, in each case in an
amount not less than the amount as is necessary to avoid the application of any
co-insurance clause contained in the related hazard insurance policy.

     Any payments by the Servicer for hazard insurance, other than as set forth
in the last paragraph of this Section 3.17, shall be deemed Servicing Advances,
reimbursable in accordance with Section 3.04(vii) or (x), to the extent not
collected from the related Mortgagor. The Servicer will comply in the
performance of this Agreement with all reasonable rules and requirements of each
insurer under any such hazard policies. Any amounts to be collected by the
Servicer under any such policies (other than amounts to be applied to the
restoration or repair of the property or amounts to be released to the Mortgagor
subject to the terms and conditions of the related Mortgage and Mortgage Note)
shall be deposited in the Custodial Account, subject to withdrawal pursuant to
Section 3.04, if received in respect of a Securitized Loan. Any cost incurred by
the Servicer in maintaining any such insurance shall not, for the purpose of
calculating distributions to Certificateholders, be added to the unpaid
principal balance of the related Securitized Loan, notwithstanding that the
terms of such Securitized Loan so permit. It is understood and agreed that no
earthquake or other additional insurance is to be required of any Mortgagor
other than pursuant to such applicable laws and regulations as shall at any time
be in force and as shall require such additional insurance. If a Mortgaged
Property or REO Property is


                                      -29-

at any time in an area identified in the Federal Register by the Federal
Emergency Management Agency as having special flood hazards and flood insurance
has been made available, the Servicer will cause to be maintained a flood
insurance policy in respect thereof. Such flood insurance shall be in an amount
equal to the lesser of (i) the unpaid principal balance of the related
Securitized Loan and (ii) the maximum amount of such insurance available for the
related Mortgaged Property under the national flood insurance program (assuming
that the area in which such Mortgaged Property is located is participating in
such program).

     In the event that the Servicer or the Sub-Servicer shall obtain and
maintain a blanket policy with an insurer having a General Policy Rating of
B:III or better in Best's Key Rating Guide (or such other rating that is
comparable to such rating) insuring against hazard losses on all of the
Securitized Loans in a Trust, it shall conclusively be deemed to have satisfied
its obligations as set forth in the first two sentences of this Section 3.17
with respect to the Securitized Loans in such Trust, it being understood and
agreed that such policy may contain a deductible clause, in which case the
Servicer shall, in the event that there shall not have been maintained on the
related Mortgaged Property or REO Property a policy complying with the first two
sentences of this Section 3.17, and there shall have been one or more losses
which would have been covered by such policy, deposit to the Custodial Account
from its own funds without right of reimbursement the amount not otherwise
payable under the blanket policy because of such deductible clause for the
benefit of the related Trust. In connection with its activities as administrator
and servicer of the Securitized Loans, the Servicer agrees to prepare and
present, on behalf of itself, the Trust and the Certificateholders, claims under
any such blanket policy in a timely fashion in accordance with the terms of such
policy.

     Section 3.18 Realization Upon Defaulted Securitized Loans.

          (a) The Servicer shall, consistent with Accepted Servicing Practices,
foreclose upon or otherwise comparably convert the ownership of properties
securing such of the Securitized Loans (including selling any such Securitized
Loans other than converting the ownership of the related properties) as come
into and continue in default and as to which no satisfactory arrangements can be
made for collection of delinquent payments. The Servicer shall be responsible
for all costs and expenses incurred by it in any such proceedings; provided,
however, that such costs and expenses will be recoverable as Servicing Advances
by the Servicer as contemplated in Section 3.04. The foregoing is subject to the
provision that, in any case in which a Mortgaged Property shall have suffered
damage from an uninsured cause, the Servicer shall not be required to expend its
own funds toward the restoration of such Mortgaged Property unless it has
determined that such restoration will increase the proceeds of liquidation of
the related Securitized Loan after reimbursement to itself for such expenses. In
instituting foreclosures or other similar proceedings, the Servicer shall
institute such proceedings in its own name on behalf of the related Trust,
unless otherwise required by applicable law or otherwise appropriate.

          (b) If the Servicer determines that it is in the best economic
interest of a Trust and the Certificateholders to sell a Distressed Securitized
Loan rather than foreclosing, the Servicer may effect such a sale. The net
proceeds of such sale shall be Liquidation Proceeds.


                                      -30-

          (c) Proceeds received in connection with any Final Recovery
Determination, as well as any recovery resulting from a partial collection of
Insurance Proceeds, Liquidation Proceeds or Condemnation Proceeds, in respect of
any Securitized Loan, will be applied in the following order of priority: first,
to unpaid Servicing Fees; second, to reimburse the Servicer or any sub-servicer
for any related unreimbursed Servicing Advances and Monthly Advances pursuant to
Section 3.04; third, to accrued and unpaid interest on the Securitized Loan, to
the date of the Final Recovery Determination, or to the Due Date prior to the
Distribution Date on which such amounts are to be distributed if not in
connection with a Final Recovery Determination; and fourth, as a recovery of
principal of the Securitized Loan. The portion of the recovery so allocated to
any unpaid Servicing Fee shall be reimbursed to the Servicer or any sub-servicer
pursuant to Section 3.04.

     Section 3.19 Enforcement of Due-On-Sale Clauses; Assumption Agreement.

     The Servicer will, to the extent it has knowledge of any conveyance or
prospective conveyance of any Mortgaged Property by any Mortgagor (whether by
absolute conveyance or contract of sale, and whether or not the Mortgagor
remains or is to remain liable under the Mortgage Note and/or the Mortgage),
exercise its rights to accelerate the maturity of such Securitized Loan under
the "due-on-sale" clause, if any, applicable thereto; provided, however, that
the Servicer shall not be required to take such action if in its sole business
judgment the Servicer believes it is not in the best interests of the related
Trust and shall not exercise any such rights if prohibited by law from doing so.
If the Servicer reasonably believes it is unable under applicable law to enforce
such "due-on-sale" clause, or if any of the other conditions set forth in the
proviso to the preceding sentence apply, the Servicer will enter into an
assumption and modification agreement from or with the person to whom such
property has been conveyed or is proposed to be conveyed, pursuant to which such
person becomes liable under the Mortgage Note and, to the extent permitted by
applicable state law, the Mortgagor remains liable thereon. The Servicer is also
authorized to enter into a substitution of liability agreement with such person,
pursuant to which the original Mortgagor is released from liability and such
person is substituted as the Mortgagor and becomes liable under the Mortgage
Note, provided that no such substitution shall be effective unless such person
satisfies the underwriting criteria of the Servicer and has a credit risk rating
at least equal to that of the original Mortgagor. In connection with any
assumption or substitution, the Servicer shall apply such underwriting standards
and follow such practices and procedures as shall be normal and usual in its
general mortgage servicing activities and as it applies to other mortgage loans
owned solely by it. The Servicer shall not take or enter into any assumption and
modification agreement, however, unless (to the extent practicable in the
circumstances) it shall have received confirmation, in writing, of the continued
effectiveness of any applicable hazard insurance policy. Any fee collected by
the Servicer in respect of an assumption, modification or substitution of
liability agreement shall be retained by the Servicer as additional servicing
compensation. In connection with any such assumption, no material term of the
Mortgage Note (including but not limited to the related Mortgage Interest Rate
and the amount of the Monthly Payment) may be amended or modified, except as
otherwise required pursuant to the terms thereof. The Servicer shall notify the
related Trustee that any such substitution, modification or assumption agreement
has been completed by the Servicer, and the Servicer shall deliver to the
Custodian the executed original of such substitution, modification or assumption
agreement, which document shall be added to the


                                      -31-

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, and the Servicer shall also deliver to the Trustee
a copy of the executed substitution, modification or assumption agreement.

     Notwithstanding the foregoing paragraph or any other provision of this
Agreement, the Servicer shall not be deemed to be in default, breach or any
other violation of its obligations hereunder by reason of any assumption of a
Securitized Loan by operation of law or by the terms of the Mortgage Note or any
assumption which the Servicer may be restricted by law from preventing, for any
reason whatever. For purposes of this Section 3.19, the term "assumption" is
deemed to also include a sale (of the Mortgaged Property) subject to the
Mortgage that is not accompanied by an assumption or substitution of liability
agreement.

     Section 3.20 Credit Risk Manager.

     The Servicer acknowledges and agrees that, under any Trust Agreement, a
Credit Risk Manager may be required to provide certain credit risk management
services as provided therein. If so, the Servicer hereby agrees to cooperate
with the Credit Risk Manager in connection with all reasonable requests made by
the Credit Risk Manager, including, without limitation, promptly providing
copies of any servicing reports and remittance advices required under this
Agreement to the Credit Risk Manager.

                                   ARTICLE IV.

                           PAYMENTS TO MASTER SERVICER

     Section 4.01 Remittances.

     On each Remittance Date, no later than 3:00 p.m. New York City time, the
Servicer shall remit on a scheduled/scheduled basis by wire transfer of
immediately available funds to the Master Servicer (a) all amounts deposited in
the Custodial Account as of the close of business on the last day of the related
Due Period (net of charges against or withdrawals from the Custodial Account
pursuant to Section 3.04), plus (b) all Monthly Advances, if any, which the
Servicer or other Advancing Person is obligated to make pursuant to Section
4.03, minus (c) any amounts attributable to Principal Prepayments, Liquidation
Proceeds, Insurance Proceeds, Condemnation Proceeds or REO Disposition Proceeds
received after the applicable Due Period, which amounts shall be remitted on the
following Remittance Date, together with any additional interest required to be
deposited in the Custodial Account in connection with such Principal Prepayment
in accordance with Section 3.03 (iii) and (vii), and minus (d) any amounts
attributable to Monthly Payments collected but due on a Due Date or Due Dates
subsequent to the first day of the month in which such Remittance Date occurs,
which amounts shall be remitted on the Remittance Date next succeeding the Due
Date related to such Monthly Payment.

     With respect to any remittance received by the Master Servicer after the
fifth Business Day following the Business Day on which such payment was due, the
Servicer shall pay to the Master Servicer interest on any such late payment at
an annual rate equal to LIBOR, adjusted as


                                      -32-

of the date of each change, plus four (4) percentage points, but in no event
greater than the maximum amount permitted by applicable law. Such interest shall
be deposited in the Custodial Account by the Servicer on the date such late
payment is made and shall cover the period commencing with the day following the
Remittance Date and ending with the Business Day on which such payment is made,
both inclusive. Such interest shall be remitted along with the distribution
payable on the next succeeding Remittance Date. The payment by the Servicer of
any such interest shall not be deemed an extension of time for payment or a
waiver of any Event of Default by the Master Servicer or any applicable Trustee.

     All remittances required to be made to the Master Servicer shall be made on
a scheduled/scheduled basis to the following wire account or to such other
account as may be specified by the Master Servicer from time to time:

          Wells Fargo Bank Minnesota, National Association
          Minneapolis, Minnesota
          ABA# 091-000-019
          Account Name: Corporate Trust Account Number 3970771416
          For further credit to: Collection Account No. 11906200

     Section 4.02 Statements to Master Servicer.

     Not later than the 10th calendar day of each month (or if such calendar day
is not a Business Day, the immediately succeeding Business Day), the Servicer
shall furnish to the Master Servicer with respect to each related Trust, or as
the Servicer and the Master Servicer may otherwise agree (a) a monthly
remittance advice in the format set forth at Exhibit D hereto for the period
ending on the first day of such calendar month (i.e., the Due Period) and (b)
all such information required pursuant to clause (a) above in an electronic file
or other similar media reasonably acceptable to the Master Servicer.

     Such monthly remittance advice shall also be accompanied with a
supplemental report provided to the Master Servicer which includes on an
aggregate basis for the previous Due Period (i) the amount of claims filed, (ii)
the amount of any claim payments made, (iii) the amount of claims denied or
curtailed and (iv) policies cancelled with respect to those Securitized Loans
covered by any PMI Policy or any other provider of primary mortgage insurance
purchased by the Trust. The Master Servicer will convert such data into a format
acceptable to each related Trustee and provide monthly reports to such Trustee
pursuant to the related Trust Agreement; provided, however, notwithstanding
anything to the contrary contained in a PMI Policy, the Servicer shall not be
required to submit any supplemental reports including the foregoing data with
respect to a PMI Policy until a reporting date that is at least 15 days after
the Servicer has received sufficient loan level information from the Seller to
appropriately code its servicing system in accordance with requirements.

     In addition, not more than 60 days after the end of each calendar year,
commencing December 31, 2002, the Servicer shall provide (as such information
becomes reasonably available to the Servicer) to the Master Servicer such
information concerning the Securitized Loans and annual remittances to the
Master Servicer with respect to the Securitized Loans in


                                      -33-

each Trust as is necessary for each Certificateholder to prepare its federal
income tax return. Such obligation of the Servicer shall be deemed to have been
satisfied to the extent that substantially comparable information shall be
provided by the Servicer to the Master Servicer and pursuant to any requirements
of the Code as from time to time are in force.

     Beginning with calendar year 2003, the Servicer shall provide the Master
Servicer and each Trustee with such information concerning the related
Securitized Loans as is necessary for such Trustee to prepare the related
Trust's federal income tax return and for any investor in the related
Certificates to prepare any required tax return.

     Section 4.03 Monthly Advances by Servicer.

     On the Business Day immediately preceding each Remittance Date, the
Servicer shall deposit in the Custodial Account from its own funds or from
amounts held for future distribution, or both, an amount equal to the aggregate
of all Monthly Advances relating to Monthly Payments which were due on the
Securitized Loans during the applicable Due Period and which were delinquent at
the close of business on the immediately preceding Determination Date. Any
amounts held for future distribution and so used shall be replaced by the
Servicer by deposit in the Custodial Account on or before any future Remittance
Date if funds in the Custodial Account on such Remittance Date shall be less
than remittances to the Master Servicer required to be made on such Remittance
Date. The Servicer shall keep appropriate records of such amounts and will
provide such records to the Master Servicer upon request. No provision in this
Agreement shall be construed as limiting the Servicer's right to (i) pass
through late collections on the related Securitized Loans in lieu of making
Monthly Advances (ii) reimburse itself for such Monthly Advances from late
collections on the related Securitized Loans or (iii) utilize an Advancing
Person (as defined below).

     The Servicer shall make Monthly Advances through the Distribution Date
immediately preceding the distribution of all Liquidation Proceeds and other
payments or recoveries (including Insurance Proceeds and Condemnation Proceeds)
with respect to the related Securitized Loans.

     The Servicer may enter into a facility with any person including the
Sub-Servicer which provides that such person (an "Advancing Person") may fund
Monthly Advances required under this Section 4.03 and/or Servicing Advances,
although no such facility shall reduce or otherwise affect the Servicer's
obligation to fund such Monthly Advances and/or Servicing Advances. Any Monthly
Advances and/or Servicing Advances made by an Advancing Person shall be
reimbursed to the Advancing Person in the same manner as reimbursements would be
made to the Servicer under Section 3.04 if such Monthly Advances or Servicing
Advance were funded by the Servicer.

     Section 4.04 Compensating Interest.

     The Servicer shall be required to deposit in the Custodial Account, and
retain therein with respect to each Principal Prepayment, the Prepayment
Interest Shortfall Amount, if any, for the related Due Period. Such deposit
shall be made from the Servicer's own funds, without reimbursement therefor, up
to an amount equal to the lesser of with respect to the Securitized


                                      -34-

Loans in each Trust (i) the Prepayment Interest Shortfall Amount or (ii) the
Servicing Fee, in each case, with respect to the Securitized Loans in such
Trust. The Servicer shall not be obligated to pay any Prepayment Interest
Shortfall Amount with respect to any Relief Act Reduction or bankruptcy.

     Section 4.05 Credit Reporting.

     For each Securitized Loan, in accordance with its current servicing
practices, the Servicer will accurately and fully report its underlying borrower
credit files to each of the following credit repositories or their successors:
Equifax Credit Information Services, Inc., Trans Union, LLC and Experian
Information Solution, Inc., on a monthly basis in a timely manner.

                                   ARTICLE V.

                          GENERAL SERVICING PROCEDURES

     Section 5.01 Servicing Compensation.

     As consideration for servicing the Securitized Loans subject to this
Agreement, the Servicer shall retain (a) the Servicing Fee for each Securitized
Loan remaining subject to this Agreement during any month and (b) Ancillary
Income. The Servicing Fee shall be payable monthly.

     The aggregate of the Servicing Fees for any month with respect to the
Securitized Loans in a Trust shall be reduced by any Prepayment Interest
Shortfall Amount with respect to the Securitized Loans in such Trust with
respect to such month. The Servicer shall be entitled to recover any unpaid
Servicing Fee out of Insurance Proceeds, Condemnation Proceeds or Liquidation
Proceeds to the extent permitted in Section 3.04 and out of amounts derived from
the operation and sale of an REO Property to the extent permitted by Section
3.12.

     Additional servicing compensation in the form of Ancillary Income shall be
retained by the Servicer only to the extent such fees or charges are received by
the Servicer. The Servicer shall also be entitled pursuant to Section 3.04 and
Section 3.06 to withdraw from the Custodial Account and Escrow Account,
respectively, as additional servicing compensation, interest or other income
earned on deposits therein, subject to Section 3.11.

     The Servicer shall be required to pay all expenses incurred by it in
connection with its servicing activities hereunder, including any fees due to
sub-servicers, and shall not be entitled to reimbursement thereof except as
specifically provided for herein.

     Section 5.02 Annual Audit Report.

     Not more than ninety days after the end of the Servicer's fiscal year
commencing with the fiscal year ending December 31, 2002, the Servicer shall, at
its own expense, cause a firm of independent public accountants (who may also
render other services to Servicer), which is a member of the American Institute
of Certified Public Accountants, to furnish to the Seller and the Master
Servicer (i) year-end audited (if available) financial statements of the
Servicer and (ii)


                                      -35-

a statement to the effect that such firm has examined certain
documents and records for the preceding fiscal year (or during the period from
the date of commencement of such Servicer's duties hereunder until the end of
such preceding fiscal year in the case of the first such certificate) and that,
on the basis of such examination conducted substantially in compliance with the
Uniform Single Attestation Program for Mortgage Bankers, such firm is of the
opinion that Servicer's overall servicing operations have been conducted in
compliance with the Uniform Single Attestation Program for Mortgage Bankers
except for such exceptions that, in the opinion of such firm, the Uniform Single
Attestation Program for Mortgage Bankers requires it to report, in which case
such exceptions shall be set forth in such statement.

     Section 5.03 Annual Officer's Certificate.

     Not more than ninety days after the end of the Servicer's fiscal year
commencing with the fiscal year ending December 31, 2002, the Servicer, at its
own expense, will deliver to the Seller and the Master Servicer a Servicing
Officer's certificate stating, as to each signer thereof, that (i) a review of
the activities of the Servicer during such preceding fiscal year and of
performance under this Agreement has been made under such officers' supervision,
and (ii) to the best of such officers' knowledge, based on such review, the
Servicer has fulfilled all its obligations under this Agreement for such year,
or, if there has been a default in the fulfillment of all such obligations,
specifying each such default known to such officers and the nature and status
thereof including the steps being taken by the Servicer to remedy such default.

                                   ARTICLE VI.

                           REPRESENTATIONS, WARRANTIES
                                 AND AGREEMENTS

     Section 6.01 Representations, Warranties and Agreements of the Servicer.

     The Servicer, as a condition to the consummation of the transactions
contemplated hereby, hereby makes the following representations and warranties
to the Seller, the Depositor, the Trustee and the Master Servicer as of the
Closing Date:

          (a) Due Organization and Authority. The Servicer is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Delaware and has all licenses necessary to carry on its business as now being
conducted and either it or its designated sub-servicer is licensed, qualified
and in good standing in each state where a Mortgaged Property is located if the
laws of such state require licensing or qualification in order to conduct a
servicing business of the type provided for herein, and in any event the
Servicer or its designated sub-servicer is in compliance with the laws of any
such state to the extent necessary to ensure the enforceability of the terms of
this Agreement; the Servicer has the full power and authority to execute and
deliver this Agreement and, together with such sub-servicer, to perform in
accordance herewith; the execution, delivery and performance of this Agreement
(including all instruments of transfer to be delivered pursuant to this
Agreement) by the Servicer and the consummation of the transactions contemplated
hereby have been duly and validly authorized; this Agreement evidences the
valid, binding and enforceable obligation of the


                                      -36-

Servicer and all requisite action has been taken by the Servicer to make this
Agreement valid and binding upon the Servicer in accordance with its terms;

          (b) Ordinary Course of Business. The consummation of the transactions
contemplated by this Agreement, taking into account the role of its
sub-servicer, is in the ordinary course of business of the Servicer;

          (c) No Conflicts. Neither the execution and delivery of this
Agreement, the acquisition of the servicing responsibilities by the Servicer or
the transactions contemplated hereby, nor the fulfillment of or compliance with
the terms and conditions of this Agreement, will conflict with or result in a
breach of any of the terms, conditions or provisions of the Servicer's
organizational documents or any legal restriction or any agreement or instrument
to which the Servicer is now a party or by which it is bound, or constitute a
default or result in an acceleration under any of the foregoing, or, taking into
account the role of its designated sub-servicer, result in the violation of any
law, rule, regulation, order, judgment or decree to which the Servicer or its
property is subject, or impair the ability of the Servicer to service the
Securitized Loans, or impair the value of the Securitized Loans;

          (d) Ability to Perform. The Servicer does not believe, nor does it
have any reason or cause to believe, that it, together with the Sub-Servicer,
cannot perform each and every covenant contained in this Agreement;

          (e) No Litigation Pending. There is no action, suit, proceeding or
investigation pending or, to the best of our knowledge, threatened against the
Servicer which, either in any one instance or in the aggregate, may result in
any material adverse change in the business, operations, financial condition,
properties or assets of the Servicer, or in any material impairment of the right
or ability of the Servicer to carry on its business substantially as now
conducted, or in any material liability on the part of the Servicer, or which
would draw into question the validity of this Agreement or of any action taken
or to be taken in connection with the obligations of the Servicer contemplated
herein, or which would be likely to impair materially the ability of the
Servicer together with the Sub-Servicer to perform under the terms of this
Agreement;

          (f) No Consent Required. No consent, approval, authorization or order

promptly to cure such breach in all material respects and, if such breach cannot
be cured, the Servicer shall, at the option of the Trustee, assign the
Servicer's rights and obligations under this Agreement (or respecting the
affected Securitized Loans) with respect to a Trust to a successor servicer
selected by the related Trustee with the prior consent and approval of the
Master Servicer. Such assignment shall be made in accordance with Section 9.01
and 9.02.

failure of the Servicer to perform its duties and service the related
Securitized Loans in material compliance with the terms of this Agreement or
(ii) the failure of the Servicer to cause any event to occur which would have
occurred if the Servicer were applying Accepted Servicing Practices under this

     Section 6.04 Indemnification with Respect to Certain Taxes and Loss of
REMIC Status.

     In the event that any REMIC elected by a Trust fails to qualify as a REMIC,
loses its status as a REMIC, or incurs federal, state or local taxes as a result

obligations set forth herein, the Servicer shall indemnify the Holder of the
related Residual Certificate, the Master Servicer, the related Trustee and the
related Trust against any and all losses, claims, damages, liabilities or
expenses ("Losses") resulting from such negligence; provided, however, that the
Servicer shall not be liable for any such Losses attributable to the action or
inaction of the related Trustee, any related Depositor, the Master Servicer or
the Holder of such Residual Certificate, as applicable, nor for any such Losses
resulting from misinformation provided by the Holder of such Residual
Certificate or any such other party on which the Servicer has relied. The
foregoing shall not be deemed to limit or restrict the rights and remedies of
the Holder of such Residual Certificate or the related Trust now or hereafter
existing at law or in equity or otherwise. Notwithstanding the foregoing,
however, in no event shall the Servicer have any liability (1) for any action or
omission that is taken in accordance with and in compliance with the express
terms of, or which is expressly permitted by the terms of, this Agreement, (2)
for any Losses other than arising out of a


                                      -39-

negligent performance by the Servicer of its duties and obligations set forth
herein, and (3) for any special or consequential damages to the related
Certificateholders.

                                  ARTICLE VII.

                                  THE SERVICER

     Section 7.01 Merger or Consolidation of the Servicer.

     The Servicer shall keep in full effect its existence, rights and franchises
as a corporation, and shall obtain and preserve its qualification to do business
as a foreign entity in each jurisdiction in which such qualification is or shall
be necessary to perform its obligations as contemplated by this Agreement.

     Any Person into which the Servicer may be merged or consolidated, or any
corporation resulting from any merger, conversion or consolidation to which the
Servicer shall be a party, or any Person succeeding to the business of the
Servicer, shall, with the prior written consent of the Master Servicer, be the
successor of the Servicer 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 shall be an institution (i) having a net worth of not less than
$15,000,000, and (ii) which is a Freddie Mac-approved or Fannie Mae-approved
servicer in good standing.

     Section 7.02 Limitation on Liability of the Servicer and Others.

     Neither the Servicer nor any of the directors, officers, employees or
agents of the Servicer shall be under any liability to the Seller, the Master
Servicer, any Depositor, any Trust or any Trustee hereunder 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 Servicer or any such person against any breach of
warranties or representations made herein, or failure to perform its obligations
in strict compliance with any standard of care set forth in this Agreement, or
any liability which would otherwise be imposed by reason of any breach of the
terms and conditions of this Agreement. The Servicer and any director, officer,
employee or agent of the 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 Servicer shall not be under any obligation to
appear in, prosecute or defend any legal action which is not incidental to its
duties to service the Securitized Loans in accordance with this Agreement and
which in its opinion may involve it in any expense or liability; provided,
however, that the Servicer may, with the consent of the related Trustee and the
Master Servicer, undertake any such action which it deems necessary or desirable
in respect of this Agreement and the rights and duties of the parties hereto. In
such event, the Servicer shall be entitled to reimbursement from the related
Trust for the reasonable legal expenses and costs of such action.


                                      -40-

     Section 7.03 Limitation on Resignation and Assignment by the Servicer.

     The Servicer shall neither assign its rights under this Agreement or the
servicing hereunder nor delegate its duties hereunder or any portion thereof, or
sell or otherwise dispose of all or substantially all of its property or assets
without, in each case, the prior written consent of the Seller, the Master
Servicer and the related Trustee, which consent, in the case of an assignment of
rights or delegation of duties, shall be granted or withheld in the discretion
of the Seller, the Master Servicer and the related Trustee, and which consent,
in the case of a sale or disposition of all or substantially all of the property
or assets of the Servicer, shall not be unreasonably withheld; provided, that in
each case, there must be delivered to the Seller, the Master Servicer and the
related Trustee a letter from the applicable Rating Agency or Rating Agencies to
the effect that such transfer of servicing or sale or disposition of assets will
not result in a qualification, withdrawal or downgrade of the then-current
rating of any of the Certificates, and provided further, without any consent or
notice the Servicer may delegate its servicing duties hereunder to the
Sub-Servicer pursuant to the Sub-Servicing Agreement. Notwithstanding the
foregoing, the Servicer, without the consent of the Seller, the Master Servicer
and the related Trustee, may retain third-party contractors to perform certain
servicing and loan administration functions, including without limitation,
hazard insurance administration, tax payment and administration, flood
certification and administration, collection services and similar functions;
provided, however, that the retention of such contractors by Servicer shall not
limit the obligation of the Servicer to service the Securitized Loans pursuant
to the terms and conditions of this Agreement.

     The Servicer shall not resign from the obligations and duties hereby
imposed on it with respect to the Securitized Loans in a Trust except by mutual
consent of the Seller, the Master Servicer and the related Trustee or upon the
determination that its duties hereunder are no longer permissible under
applicable law and such incapacity cannot be cured by the Servicer. Any such
determination permitting the resignation of the Servicer shall be evidenced by
an Opinion of Counsel to such effect delivered to the Seller, the Master
Servicer and the related Trustee which Opinion of Counsel shall be in form and
substance acceptable to the Seller, the Master Servicer and the related Trustee.
No such resignation shall become effective until a successor acceptable to the
Master Servicer shall have assumed the Servicer's responsibilities and
obligations hereunder in the manner provided in Section 9.01.

     Without in any way limiting the generality of this Section 7.03, in the
event that the Servicer either shall assign this Agreement or the servicing
responsibilities hereunder or delegate its duties hereunder or any portion
thereof or sell or otherwise dispose of all or substantially all of its property
or assets, without the prior written consent of the Seller, the Master Servicer
and the Trustee (except as provided by the first paragraph of this Section 7.03
and Section 7.04), then such parties shall have the right to terminate this
Agreement upon notice given as set forth in Section 8.01, without any payment of
any penalty or damages and without any liability whatsoever to the Servicer or
any third party.

     Section 7.04 Sub-Servicing Agreements; Sub-Servicing Acknowledgment
Agreement; Successor Sub-Servicer.

          (a) The Servicer may enter into sub-servicing agreements for any
servicing and administration of the Securitized Loans with any institution which
(i) is an approved Fannie Mae or Freddie Mac Seller/Servicer as indicated in
writing, and (ii) represents and warrants that it is in compliance with the laws
of each state as necessary to enable it to perform its obligations under such
sub-servicing agreement. For this purpose, sub-servicing shall not be deemed to
include the use of a tax service, or services for reconveyance, insurance or
brokering REO Property. The Servicer shall give prior written notice to the
Master Servicer and the Trustee of the appointment of any sub-servicer and shall
furnish to the Master Servicer and the Trustee a copy of such sub-servicing
agreement. For purposes of this Agreement, the Servicer shall be deemed to have
received payments on Securitized Loans immediately upon receipt by any
sub-servicer of such payments. Any such sub-servicing agreement shall be
acceptable to the Master Servicer and the related Trustee and shall be
consistent with and not violate the provisions of this Agreement. Each
sub-servicing agreement shall provide that a successor servicer shall have the
option to terminate such agreement without payment of any fees if the
predecessor Servicer is terminated or resigns.

          (b) The Servicer may terminate any sub-servicing agreement to which it
is a party in accordance with the terms and conditions of such sub-servicing
agreement and either itself directly service the related Securitized Loans or
enter into a sub-servicing agreement with a successor sub-servicer that
qualifies under Section 7.04(a).

          (c) Notwithstanding any sub-servicing agreement or the provisions of
this Agreement relating to agreements or arrangements between the Servicer and a
sub-servicer or reference to actions taken through a sub-servicer or otherwise,
the Servicer shall remain obligated and primarily liable to the Trustee, the
Master Servicer, the Trust and the Certificateholders for the servicing and
administering of the Securitized Loans in accordance with the provisions hereof
without diminution of such obligation or liability by virtue of such
sub-servicing agreements or arrangements or by virtue of indemnification from
the sub-servicer and to the same extent and under the same terms and conditions
as if the Servicer alone were servicing and administering the Securitized Loans.
The Servicer shall be entitled to enter into any agreement with a sub-servicer
for indemnification of the Servicer by such sub-servicer and nothing contained
in this Agreement shall be deemed to limit or modify such indemnification.

     Section 7.05 Inspection.

     The Servicer shall offer each Trustee and the Master Servicer, upon
reasonable advance notice, during normal business hours, access to all records
maintained by the Servicer in respect of its rights and obligations hereunder
and access to officers of the Servicer responsible for such obligations. Upon
request, the Servicer shall furnish to each Trustee and the Master Servicer its
most recent publicly available financial statements and such other information
relating to its capacity to perform its obligations under this Agreement.


                                      -42-

                                  ARTICLE VIII.

                                   TERMINATION

     Section 8.01 Termination for Cause.

     This Agreement shall be terminable at the option of the Master Servicer or
the related Trustee if any of the following events of default exist on the part
of the Servicer:

               (i) any failure by the Servicer to remit to the Master Servicer
any payment required to be made under the terms of this Agreement which
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 received by the Servicer from the Master Servicer or a related Trustee; or

               (ii) failure by the Servicer duly to observe or perform in any
material respect any other of the covenants or agreements on the part of the
Servicer set forth in this Agreement which continues unremedied for a period of
15 days following the Servicer's receipt of written notice of such failure from
the Master Servicer or a related Trustee; or

               (iii) failure by the Servicer to maintain its license or to cause
its designated sub-servicer to do business or service residential Securitized
Loans in any jurisdiction, if required by such jurisdiction, where a Mortgaged
Property is located; or

               (iv) a decree or order of a court or agency or supervisory
authority having jurisdiction for the appointment of a conservator or receiver
or liquidator in any insolvency, readjustment of debt, including bankruptcy,
marshaling of assets and liabilities or similar proceedings, or for the
winding-up or liquidation of its affairs, shall have been entered against the
Servicer and such decree or order shall have remained in force undischarged or
unstayed for a period of 60 days; or

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

               (vi) the Servicer shall admit in writing its inability to pay its
debts generally as they become due, file a petition to take advantage of any
applicable insolvency, bankruptcy or reorganization statute, make an assignment
for the benefit of its creditors, voluntarily suspend payment of its obligations
or cease its normal business operations for three Business Days; or

               (vii) the Servicer ceases to meet or to cause its designated
sub-servicer to meet the qualifications of a Fannie Mae or Freddie Mac
seller/servicer; or

               (viii) the Servicer attempts to assign the servicing of the
Securitized Loans or its right to servicing compensation hereunder or the
Servicer attempts to sell or


                                      -43-

otherwise dispose of all or substantially all of its property or assets or to
assign this Agreement or the servicing responsibilities hereunder or to delegate
its duties hereunder or any portion thereof, in each case without complying
fully with the provisions of Section 7.03 or Section 7.04.

     In each and every such case, so long as an event of default shall not have
been remedied within the applicable cure period, in addition to whatever rights
the Master Servicer or a related Trustee may have at law or equity to damages,
including injunctive relief and specific performance, the Trustee or the Master
Servicer, by notice in writing to the Servicer, and with the consent of the
other party, may terminate all the rights and obligations of the Servicer under
this Agreement and in and to the servicing contract established hereby and the
proceeds thereof.

     Upon receipt by the Servicer of such written notice, all authority and
power of the Servicer under this Agreement, whether with respect to the
Securitized Loans or otherwise, shall pass to and be vested in a successor
servicer appointed by the Trustee or the Master Servicer, as the case may be,
with the consent of the other party. Upon written request from the Master
Servicer, the Servicer shall prepare, execute and deliver to the successor
servicer or the Trustee any and all documents and other instruments, place in
such successor's possession all Servicing Files, and do or cause to be done all
other acts or things necessary or appropriate to effect the purposes of such
notice of termination, including but not limited to the transfer and endorsement
or assignment of the Securitized Loans and related documents, at the Servicer's
sole expense. The Servicer shall cooperate with the Master Servicer and such
successor in effecting the termination of the 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 the Servicer to the Custodial Account or Escrow Account or thereafter
received with respect to the Securitized Loans.

     By a written notice, the Trustee or the Master Servicer, with the consent
of the other party, may waive any default by the Servicer in the performance of
its obligations hereunder and its consequences. Upon any waiver of a past
default, such default shall cease to exist, and any Event of Default arising
therefrom shall be deemed to have been remedied for every purpose of this
Agreement. No such waiver shall extend to any subsequent or other default or
impair any right consequent thereon except to the extent expressly so waived.

     Section 8.02 Termination Without Cause.

          (a) This Agreement shall terminate upon: (i) the later of (a) the
distribution of the final payment or liquidation proceeds on the last
Securitized Loan to the Master Servicer or the Trust, and (b) the disposition of
all REO Property acquired upon foreclosure of the last Securitized Loan and the
remittance of all funds due hereunder or (ii) mutual consent of the Servicer and
the Master Servicer in writing, provided such termination is also acceptable to
the applicable Rating Agency or Rating Agencies. In addition, with the prior
written consent of the Master Servicer, the Seller or its designee may terminate
this Agreement with respect to all of the Securitized Loans, without cause,
provided, that the Seller or its designee gives the Servicer 30 days' notice.
Any such notice of termination shall be in writing and delivered to the Servicer
and the Master Servicer by registered mail to the address set forth in Section
9.03. The Seller or its designee and the Servicer shall comply with the
termination procedures set forth in Section


                                      -44-

9.01 hereof. All unreimbursed Servicing Fees, Servicing Advances and Monthly
Advances still owing the Servicer shall be paid by the Seller or its designee or
the successor servicer from its own funds within 5 Business Days of the date of
such termination without right of reimbursement from the Trust. In connection
with any termination pursuant to clause (ii) of the first sentence of this
Section 8.02(a), all unreimbursed Servicing Fees, Servicing Advances and Monthly
Advances still owing the Servicer shall be paid at the time of such termination
by the Trust.

     Upon a termination of the Servicer for cause pursuant to Section 8.01, all
unreimbursed Servicing Fees, Servicing Advances and Monthly Advances still owing
the Servicer shall be paid by the Trust as such amounts are received from the
related Securitized Loans. In connection with any termination pursuant to the
second sentence of this Section 8.02(a), the Seller or its designee or the
successor servicer will be responsible for reimbursing the Servicer for all
unreimbursed out-of-pocket Servicing Advances, Monthly Advances and Servicing
Fees and other reasonable and necessary out-of-pocket costs associated with any
transfer of servicing at the time of such transfer of servicing. Any invoices
received by the Servicer after termination will be forwarded to the Seller or
its designee, and the Seller or its designee or the successor servicer shall pay
such invoices within five (5) Business Days upon receipt from the Servicer.

          (b) In the event that the Servicer decides to terminate its
obligations under this Agreement as set forth in clause (ii) of Section 8.02(a),
the Servicer agrees that it will continue to service the Securitized Loans
beyond the prescribed termination date until such time as the Trustee, using
reasonable commercial efforts, is able to appoint a successor servicer
acceptable to and the Master Servicer and otherwise meeting the characteristics
of Sections 7.01 and 9.01.

                                   ARTICLE IX.

                            MISCELLANEOUS PROVISIONS

     Section 9.01 Successor to the Servicer.

     Simultaneously with the termination of the Servicer's responsibilities and
duties under this Agreement (a) pursuant to Sections 6.02, 7.03, 8.01 or
8.02(a)(ii), the Master Servicer shall (i) within 90 days of the Servicer's
receipt of notice of such termination, succeed to and assume all of the
Servicer's responsibilities, rights, duties and obligations under this Agreement
(except that the Master Servicer shall immediately assume all of the obligations
of the Servicer to make Monthly Advances), or (ii) appoint a successor having
the characteristics set forth in clauses (i) and (ii) of Section 7.01 and which
shall succeed to all rights and assume all of the responsibilities, duties and
liabilities of the Servicer under this Agreement simultaneously with the
termination of the Servicer's responsibilities, duties and liabilities under
this Agreement; or (b) as a result of termination of the Servicer without cause
by the Seller pursuant to Section 8.02 hereof, the Seller shall appoint a
successor having the characteristics set forth in clauses (i) and (ii) of
Section 7.01 and which shall succeed to all rights and assume all of the
responsibilities, duties and liabilities of the Servicer under this Agreement
simultaneously with the termination of the Servicer's responsibilities, duties
and liabilities under this Agreement. Any successor to the Servicer shall be
subject to the approval of the Master Servicer and the Trustee and, to the
extent


                                      -45-

required by the Trust Agreement, shall be a member in good standing of the MERS
system (if any of the Securitized Loans are MERS Eligible Securitized Loans,
unless such Securitized Loans are withdrawn from MERS and Assignments of
Mortgage are recorded in favor of the Trust at the expense of the successor
servicer). The final approval of a successor servicer shall be conditioned upon
the receipt by the Trustee, the Master Servicer and the Seller of a letter from
the applicable Rating Agency or Rating Agencies to the effect that such transfer
of servicing will not result in a qualification, withdrawal or downgrade of the
then-current rating of any of the Certificates. In connection with such
appointment and assumption, the Master Servicer or the Seller, as applicable,
may make such arrangements for the compensation of such successor out of
payments on Securitized Loans as it and such successor shall agree, provided,
however, that no such compensation shall be in excess of the Servicing Fee
permitted under this Agreement. In the event that the Servicer's duties,
responsibilities and liabilities under this Agreement should be terminated
pursuant to the aforementioned sections, the Servicer shall discharge such
duties and responsibilities during the period from the date it acquires
knowledge of such termination until the effective date thereof with the same
degree of diligence and prudence which it is obligated to exercise under this
Agreement, and shall take no action whatsoever that might impair or prejudice
the rights or financial condition of its successor. The resignation or removal
of the Servicer pursuant to the aforementioned sections shall not become
effective until a successor servicer shall be appointed pursuant to this Section
9.01, or until the Master Servicer succeeds to and assumes all of the Servicer's
responsibilities, rights, duties and obligations pursuant to this Section 9.01,
and shall in no event relieve the Servicer of the representations and warranties
made pursuant to Section 6.01 and the remedies available to the Trustee, the
Trust, the Master Servicer and the Seller under Section 6.02 and 6.03, it being
understood and agreed that the provisions of such Sections 6.01, 6.02 and 6.03
shall be applicable not only to such successor servicer but also to the Servicer
notwithstanding any such resignation or termination of the Servicer, or the
termination of this Agreement. Notwithstanding the foregoing, the Master
Servicer, in its capacity as successor servicer, shall not be responsible for
the lack of information and/or documents that it cannot obtain through
reasonable efforts.

     Within a reasonable period of time, but in no event longer than 30 days
after the appointment of a successor entity, the Servicer shall prepare, execute
and deliver to the successor entity any and all documents and other instruments,
place in such successor's possession all Servicing Files, and do or cause to be
done all other acts or things necessary or appropriate to effect the purposes of
such notice of termination, including but not limited to the transfer and
endorsement of the Mortgage Notes and related documents, and the preparation and
recordation of Assignments of Mortgage. The Servicer shall cooperate with the
Master Servicer or the Seller, as applicable, and such successor in effecting
the termination of the Servicer's responsibilities and rights hereunder and the
transfer of servicing responsibilities to the successor servicer, including
without limitation, the transfer to such successor for administration by it of
all cash amounts which shall at the time be credited by the Servicer to the
Custodial Account or Escrow Account or thereafter received with respect to the
Securitized Loans.

     Any successor servicer appointed as provided herein shall execute,

the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof. Any part, provision, representation or warranty of

     It is the intention of the parties that the Seller is conveying, and the

servicing rights) related thereto.

     Section 9.10 Successors and Assigns; Assignment of Servicing Agreement.

     This Agreement shall bind and inure to the benefit of and be enforceable by

This Agreement shall not be assigned, pledged or hypothecated by the Servicer to
a third party except in accordance with Section 7.03 and shall not be assigned,
pledged or hypothecated by the Seller except as and to the extent provided in
Section 9.11.

     Section 9.11 Assignment by Seller.

     The Seller shall have the right, upon notice to but without the consent of
the Servicer, to assign, in whole or in part (but exclusive of such Seller's
rights and obligations as owner of the servicing rights relating to Securitized
Loans), its interest under this Agreement with respect to Securitized Loans
which will be owned by the related Trust to the related Depositor, which in turn
shall assign such rights to such Trust, and such Trust then shall succeed to all
such rights of the Seller under this Agreement. All references to the Seller in
this Agreement shall be deemed to include its assignee or designee and any
subsequent assignee or designee, specifically including, with respect to each
Securitized Loan, the related Trust and the related Trustee.

     Section 9.12 Amendment.

     This Agreement may be amended in writing from time to time by the parties,

provide the other parties and each such Trustee with an Opinion of Counsel that
(i)such amendment is permitted under the terms of this Agreement, (ii) the
Servicer has complied with all applicable requirements of this Agreement, and
(iii)) such amendment will not materially adversely affect the interest of any
Trust or the related Certificateholders in the Securitized Loans.

     Any such amendment shall be deemed not to adversely affect in any material
respect any of the interest of Certificateholders in the Securitized Loans if
each related Trustee receives written confirmation from the applicable Rating
Agency or Rating Agencies that such amendment will not cause such Rating Agency
or Rating Agencies to reduce, qualify or


                                      -50-

withdraw the then current rating assigned to the related Certificates (and any
Opinion of Counsel requested by a party in connection with any such amendment
may rely expressly on such confirmation as the basis therefor).

     No term or provision of this Agreement may be waived or modified unless
such waiver or modification is in writing, signed by the party against whom such
waiver or modification is sought to be enforced.

     The exhibits to this Agreement are hereby incorporated and made a part
hereof and are an integral part of this Agreement.

     Section 9.15 Intended Third Party Beneficiary.

     Notwithstanding any provision herein to the contrary, the parties to this
Agreement agree that it is appropriate, in furtherance of the intent of such
parties as set forth herein, that each Trustee and each Trust receive the
benefit of the provisions of this Agreement as an intended third party
beneficiary of this Agreement to the extent of such provisions with respect to
the related Securitized Loans. The Servicer shall have the same obligations to
the related Trustee and the related Trust as if it were a party to this
Agreement, and each such Trustee and Trust shall have the same rights and
remedies to enforce the provisions of this Agreement as if it were a party to
this Agreement. The Servicer shall only take direction from the Master Servicer
(if direction by the Master Servicer is required under this Agreement) unless
otherwise directed by this Agreement. Notwithstanding the foregoing, all rights
and obligations of a Trust, the related Trustee and the Master Servicer
hereunder (other than the right to indemnification) with respect to the related
Securitized Loans shall terminate upon the termination of such Trust pursuant to
the related Trust Agreement.

examination of any Trustee or the Master Servicer by any such authority or for
the purposes specified in any Trust Agreement or this Agreement shall not
constitute a breach of its obligations under this Section 9.19, and shall not
require the prior consent of the Servicer.

Form 332

Calculation of Realized Loss

Purpose

To provide the Servicer with a form for the calculation of any Realized Loss (or
gain) as a result of a Securitized Loan having been foreclosed and Liquidated.

Distribution

The Servicer will prepare the form in duplicate and send the original together
with evidence of conveyance of title and appropriate supporting documentation to
the Master Servicer with the Monthly Accounting Reports which supports the
Securitized Loan's removal from the Securitized Loan Activity Report. The
Servicer will retain the duplicate for its own records.

Due Date

With respect to any liquidated Securitized Loan, the form will be submitted to
the Master Servicer no later than the date on which statements are due to the
Master Servicer under Section 4.02 of this Agreement (the "Statement Date") in
the month following receipt of final liquidation proceeds and supporting
documentation relating to such liquidated Securitized Loan; provided, that if
such Statement Date is not at least 30 days after receipt of final liquidation
proceeds and supporting documentation relating to such liquidated Securitized
Loan, then the form will be submitted on the first Statement Date occurring
after the 30th day following receipt of final liquidation proceeds and
supporting documentation.

Preparation Instructions

The numbers on the form correspond with the numbers listed below.

1.     The actual Unpaid Principal Balance of the Securitized Loan.

2.     The Total Interest Due less the aggregate amount of servicing fee that
       would have been earned if all delinquent payments had been made as
       agreed.

3-7.   Complete as necessary. All line entries must be supported by copies of
       appropriate statements, vouchers, receipts, canceled checks, etc., to
       document the expense. Entries not properly documented will not be
       reimbursed to the Servicer.

8.     Accrued Servicing Fees based upon the Scheduled Principal Balance of the
       Securitized Loan as calculated on a monthly basis.

10.    The total of lines 1 through 9.

Credits

11-17. Complete as necessary. All line entries must be supported by copies of
       the appropriate claims forms, statements, payment checks, etc. to
       document the credit. If the Securitized Loan is subject to a Bankruptcy
       Deficiency, the difference between the Unpaid Principal Balance of the
       Note prior to the Bankruptcy Deficiency and the Unpaid Principal Balance
       as reduced by the Bankruptcy Deficiency should be input on line 16.

18.    The total of lines 11 through 17.

Total Realized Loss (or Amount of Any Gain)


                                       D-7

19.    The total derived from subtracting line 18 from 10. If the amount
       represents a realized gain, show the amount in parenthesis ( )

                        AMENDMENT TO SERVICING AGREEMENT

     THIS AMENDMENT to the Servicing Agreement dated as of March 1, 2002,
between WELLS FARGO BANK MINNESOTA, NATIONAL ASSOCIATION, as Master Servicer,
THORNBURG MORTGAGE HOME LOANS, INC. ("TMHL"), as Seller and as Servicer (the
"Servicing Agreement") is made as of the 1st day of December, 2002, by and
between the MASTER SERVICER, the SERVICER and the SELLER (the "Amendment").

                                   WITNESSETH:

     WHEREAS, TMHL and the Master Servicer are parties to the Servicing
Agreement wherein the Servicer has agreed to service Securitized Loans pursuant
to the terms of the Servicing Agreement;

     WHEREAS, the Master Servicer has requested that certain additional
servicing certifications be provided to the Master Servicer and that certain
time periods for the provision of reports be modified, and the Servicer has
agreed to such modifications; and

     WHEREAS, the Master Servicer and TMHL desire to amend the Servicing
Agreement to reflect those requirements;

     NOW, THEREFORE, for and in consideration of good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, and
of the mutual covenants herein contained, the parties hereto hereby agree as
follows:

     1. Capitalized terms used and not defined in this Amendment shall have the
meanings given to such terms in the Servicing Agreement.

     2. Article I entitled "Definitions" is amended as follows:

          a.   The definition of "Agreement" is modified to read as follows:

               "This Servicing Agreement, as amended by that certain Amendment
               to Servicing Agreement dated as of December 1, 2002, and all
               other amendments hereof and supplements hereto."

          b.   The definition of "Sub-Servicing Acknowledgment Agreement" is
               modified to read as follows:

               "That certain Sub-Servicing Acknowledgment Agreement, dated as of
               March 1, 2002, by and between the Servicer and the Sub-Servicer,
               as amended by that certain Amendment to Sub-Servicing
               Acknowledgment Agreement, dated as of December 1, 2002 by and
               between the Servicer and the Sub-Servicer."

     3. Section 5.02 entitled "Annual Audit Report" is amended by:

          a.   deleting the phrase "Not more than ninety (90) days after the end
               of the Servicer's fiscal year" in the first sentence; and after
               the phrase "own expense" add the following: "use its best efforts
               by March 20 of each year, but in no event later than March 30 of
               each year,"; and

          b.   deleting the phrase "commencing with the fiscal year ending
               December 31, 2002" in the first sentence.

          Therefore, Section 5.02 now reads in its entirety as follows:

               The Servicer shall, at its own expense, use its best efforts by
               March 20 of each year, but in no event later than March 30 of
               each year, cause a firm of independent public accountants (who
               may also render other services to Servicer), which is a member of
               the American Institute of Certified Public Accountants, to
               furnish to the Seller and the Master Servicer (i) year-end
               audited (if available) financial statements of the Servicer and
               (ii) a statement to the effect that such firm has examined
               certain documents and records for the preceding fiscal year (or
               during the period from the date of commencement of such
               Servicer's duties hereunder until the end of such preceding
               fiscal year in the case of the first such certificate) and that,
               on the basis of such examination conducted substantially in
               compliance with the Uniform Single Attestation Program for
               Mortgage Bankers, such firm is of the opinion that Servicer's
               overall servicing operations have been conducted in compliance
               with the Uniform Single Attestation Program for Mortgage Bankers
               except for such exceptions that, in the opinion of such firm, the
               Uniform Single Attestation Program for Mortgage Bankers requires
               it to report, in which case such exceptions shall be set forth in
               such statement.

     4. Section 5.03 entitled "Annual Officer's Certificate" is amended by:

          a.   deleting the phrase "Not more than ninety (90) days after the end
               of the Servicer's fiscal year" in the first sentence; and prior
               to the phrase "deliver to the Seller" add the following: "using
               its best efforts by March 20 of each year, but in no event later
               than March 30 of each year"; and

          b.   deleting the phrase "commencing with the fiscal year ending
               December 31, 2002" in the first sentence.

          Therefore, Section 5.03 now reads in its entirety as follows:

               The Servicer, at its own expense, will, using its best efforts by
               March 20 of each year, but in no event later than March 30 of
               each


                                      -2-

               year, deliver to the Seller and the Master Servicer a Servicing
               Officer's certificate stating, as to each signer thereof, that
               (i) a review of the activities of the Servicer during such
               preceding fiscal year and of performance under this Agreement has
               been made under such officers' supervision, and (ii) to the best
               of such officers' knowledge, based on such review, the Servicer
               has fulfilled all its obligations under this Agreement for such
               year, or, if there has been a default in the fulfillment of all
               such obligations, specifying each such default known to such
               officers and the nature and status thereof including the steps
               being taken by the Servicer to remedy such default.

     5. The following is added as Section 5.04:

          Section 5.04. Servicer's Certification.

               a. An officer of the Servicer shall, using its best efforts by
March 20 of each year, but no later than March 30 of each year, (or if not a
Business Day, the immediately preceding Business Day), or at any other time upon
thirty (30) days written request, execute and deliver an Officer's Certificate
to the Master Servicer for the benefit of such Master Servicer and its officers,
directors and affiliates, certifying as to the following matters:

                    (i)  Based on my knowledge, the information in the annual
                         statement of compliance furnished pursuant to Section
                         5.03, the annual independent public accountant's
                         servicing report furnished pursuant to Section 5.02 and
                         all servicing reports, officer's certificates and other
                         information relating to the servicing of the
                         Securitized Loans submitted to the Master Servicer
                         taken as a whole, does not contain any untrue statement
                         of a material fact or omit to state a material fact
                         necessary to make the statements made, in light of the
                         circumstances under which such statements were made,
                         not misleading as of the date of this certification;

                    (ii) The servicing information required to be provided to
                         the Master Servicer by the Servicer under this
                         Servicing Agreement has been provided to the Master
                         Servicer;

                    (iii) I am responsible for reviewing the activities
                          performed by the Servicer under the Servicing
                          Agreement and based upon the review required by the
                          Servicing Agreement, and except as disclosed in the
                          annual statement of compliance, the annual independent
                          public accountant's servicing report


                                      -3-

                         and all servicing reports, officer's certificates and
                         other information relating to the servicing of the
                         Securitized Loans submitted to the Master Servicer, the
                         Servicer has, as of the date of this certification
                         fulfilled its obligations under the Servicing
                         Agreement; and

                    (iv) I have disclosed to the Master Servicer all significant
                         deficiencies relating to the Servicer's compliance with
                         the minimum servicing standards in accordance with a
                         review conducted in compliance with the Uniform Single
                         Attestation Program for Mortgage Bankers or similar
                         standard as set forth in the Servicing Agreement.

               b. The Servicer shall indemnify and hold harmless the Master
Servicer and its officers, directors, agents and affiliates from and against any
losses, damages, penalties, fines, forfeitures, reasonable legal fees and
related costs, judgments and other costs and expenses arising out of or based
upon a breach by the Servicer or any of its officers, directors, agents or
affiliates of its obligations under this Section 5.04 or the negligence, bad
faith or willful misconduct of the Servicer in connection therewith. If the
indemnification provided for herein is unavailable or insufficient to hold
harmless the Master Servicer, then the Servicer agrees that it shall contribute
to the amount paid or payable by the Master Servicer as a result of losses,
claims, damages or liabilities of the Master Servicer in such proportion as is
appropriate to reflect the relative fault of the Master Servicer on the one hand
and the Servicer on the other in connection with a breach of the Servicer's
obligations under this Section 5.04 or the Servicer's negligence, bad faith or
willful misconduct in connection therewith.

     6. Section 8.01 entitled "Termination for Cause" is amended by:

          a.   deleting the word "or" at the end of subsection (vii);

          c.   inserting the following after subsection (viii):

               (ix) failure by the Servicer to duly perform, within the required
               time period, its obligations under Sections 5.02, 5.03 or 5.04
               which failure continues unremedied for a period of thirty (30)
               days after the date on which written notice of such failure,
               requiring the same to be remedied, shall have been given to the
               Servicer by any party to this Servicing Agreement or by any
               master servicer responsible for master servicing the Securitized
               Loans pursuant to a securitization of such Securitized Loans.


                                      -4-

     7. The Sub-Servicer's performance in accordance with the Sub-Servicing
Acknowledgment Agreement shall satisfy the Servicer's obligations under the
Servicing Agreement, as amended hereby.

     8. Except as amended herein, the terms and conditions and obligations of
the Agreement shall remain in full force and effect.

     9. This Amendment may be executed in any counterparts, each of which shall
be deemed to be an original and all of which counterparts shall together
constitute but one and the same instrument.

     10. This Amendment becomes effective as of the date first written above.

     IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
duly executed on their behalf by the undersigned, thereunto duly authorized, as
of the day and year first above written.

                               SERVICING AGREEMENT

     This Second Amendment ("Amendment") to the Servicing Agreement, dated as of

                                   WITNESSETH:

Master Servicer or any Depositor to the utilization of any Subcontractor. TMHL
shall promptly upon request provide to any Master Servicer and any Depositor (or
any designee of the Depositor, such as a master servicer or administrator) a
written description of (i) which (if any) of such Subcontractors are
"participating in the servicing function" within the meaning of Item 1122 of
Regulation AB, and (ii) which elements of the Servicing Criteria will be
addressed in assessments of compliance provided by each Subcontractor identified
pursuant to clause (i) of this paragraph.

     As a condition to the utilization of any Subcontractor determined by TMHL
to be "participating in the servicing function" within the meaning of Item 1122
of Regulation AB, TMHL shall cause any such Subcontractor used by TMHL (or by
any Subservicer) for the benefit of the Master Servicer and any Depositor to
comply with the provisions of this Amendment to the same extent as if such
Subcontractor were TMHL. TMHL shall be responsible for obtaining from each
Subcontractor and delivering to any Depositor any assessment of compliance and
attestation and the other certifications required to be delivered by such
Subcontractor under Section 6, in each case as and when required to be
delivered.

     5. Indemnification; Remedies.

     (a) TMHL shall indemnify the Master Servicer and any Depositor and the
respective present and former directors, officers, employees and agents of each
of the foregoing, and shall hold each of them harmless from and against any
losses, damages, penalties, fines, forfeitures, legal fees and expenses and
related costs, judgments, and any other costs, fees and expenses that any of
them may sustain solely and directly arising out of or based upon:

          (i) (A) any untrue statement of a material fact contained in any
information, report, certification, accountants' letter or other material
provided in written or electronic form under this Amendment, by or on behalf of
TMHL, or provided under any of Sections of this Amendment, as applicable, by or
on behalf of any Subservicer or Subcontractor (collectively, the "Servicer
Information"), or (B) the omission to state in Servicer Information a material
fact required to be stated in Servicer Information or necessary in order to make
the statements therein, in the light of the circumstances under which they were
made, not misleading; provided, by way of clarification, that clause (B) of this
paragraph shall be construed solely by reference to Servicer Information and not
to any other information communicated in connection with a sale or purchase of
securities, without regard to whether Servicer Information or any portion
thereof is presented together with or separately from such other information;

          (ii) any breach by TMHL of its obligations under this Amendment,
including particularly any failure by TMHL, any Subservicer or any Subcontractor
to deliver any information, report, certification, accountants' letter or other
material when and as required under this Amendment, as applicable, including any
failure by TMHL to identify pursuant to Section 3 any Subcontractor
"participating in the servicing function" within the meaning of Item 1122 of
Regulation AB; or

          (iii) any breach by TMHL of a representation or warranty set forth in
Section 4(a) or in a writing furnished pursuant to Section 4(b) and made as of a
date prior to the


                                       -5-

closing date of the related Securitization Transaction, to the extent that such
breach is not cured by such closing date, or any breach by TMHL of a
representation or warranty in a writing furnished pursuant to Section 4(b) to
the extent made as of a date subsequent to such closing date; or

          (iv) the gross negligence of TMHL in connection with its performance
under this Amendment.

     If the indemnification provided for herein is unavailable or insufficient
to hold harmless an indemnified party, then TMHL agrees that it shall contribute
to the amount paid or payable by such indemnified party in such proportion as is
appropriate to reflect the relative fault of such indemnified party on the one
hand and TMHL on the other.

     In the case of any failure of performance described in clause (a)(ii) of
this Section, TMHL shall promptly reimburse the Master Servicer, any Depositor,
as applicable, and each Person responsible for the preparation, execution or
filing of any report required to be filed with the Commission with respect to
such Securitization Transaction, or for execution of a certification pursuant to
Rule 13a-14(d) or Rule 15d-14(d) under the Exchange Act with respect to such
Securitization Transaction, for all costs reasonably incurred by each such party
in order to obtain the information, report, certification, accountants' letter
or other material not delivered as required by TMHL, any Subservicer or any
Subcontractor.

     This indemnification shall survive the termination of this Amendment or the
termination of any party to this Amendment.

     (b) (i) Any failure by TMHL, any Subservicer or any Subcontractor to
deliver any information, report, certification, accountants' letter or other
material when and as required under this Amendment, as applicable, or any breach
by TMHL of a representation or warranty set forth in Section 4(a) or in a
writing furnished pursuant to Section 4(b) and made as of a date prior to the
closing date of the related Securitization Transaction, to the extent that such
breach is not cured by such closing date, or any breach by TMHL of a
representation or warranty in a writing furnished pursuant to Section 4(b) to
the extent made as of a date subsequent to such closing date, which failure or
breach continues unremedied for a period of ten (10) calendar days after the
date on which written notice of such failure, requiring the same to have been
remedied, shall have been given to TMHL by the Master Servicer or Depositor,
shall constitute an Event of Default with respect to TMHL under this Amendment,
and shall entitle the Master Servicer or Depositor, as applicable, in its sole
discretion to terminate the rights and obligations of TMHL as servicer under
this Amendment pursuant to this Amendment; provided that to the extent that any
provision of this Amendment expressly provides for the survival of certain
rights or obligations following termination of TMHL as servicer, such provision
shall be given effect.

     (ii) Any failure by TMHL, any Subservicer or any Subcontractor to deliver
any information, report, certification or accountants' letter when and as
required under Section 6, including (except as provided below) any failure by
TMHL to identify pursuant to Section 3 any Subcontractor "participating in the
servicing function" within the meaning of Item 1122 of Regulation AB, which
failure continues unremedied for a period of ten (10) calendar days after the
date on which written notice of such failure, requiring the same to have been
remedied, shall


                                       -6-

have been given to TMHL by the Master Servicer or Depositor, shall constitute an
Event of Default with respect to TMHL under this Amendment, and shall entitle
the Purchaser, Master Servicer or Depositor, as applicable, in its sole
discretion to terminate the rights and obligations of TMHL as servicer pursuant
to the terms of this Amendment; provided that to the extent that any provision
of this Amendment expressly provides for the survival of certain rights or
obligations following termination of TMHL as servicer, such provision shall be
given effect.

     Neither the Master Servicer nor any Depositor shall be entitled to
terminate the rights and obligations of TMHL pursuant to this subparagraph
(b)(ii) if a failure of TMHL to identify a Subcontractor "participating in the
servicing function" within the meaning of Item 1122 of Regulation AB was
attributable solely to the role or functions of such Subcontractor with respect
to mortgage loans other than the Mortgage Loans.

     6. Annual Statement as to Compliance.

     (i) On or before March 1 of each calendar year, commencing in 2007, TMHL
shall deliver to the Master Servicer and any Depositor a statement of compliance
addressed to such Master Servicer and such Depositor and signed by an authorized
officer of TMHL, to the effect that (i) a review of TMHL's activities during the
immediately preceding calendar year (or applicable portion thereof) and of its
performance under this Amendment during such period has been made under such
officer's supervision, and (ii) to the best of such officers' knowledge, based
on such review, TMHL has fulfilled all of its obligations under this Amendment
in all material respects throughout such calendar year (or applicable portion
thereof) or, if there has been a failure to fulfill any such obligation in any
material respect, specifically identifying each such failure known to such
officer and the nature and the status thereof.

     (ii) On or before March 1 of each calendar year, commencing in 2007, TMHL
shall:

     (A) deliver to the Master Servicer and any Depositor a report regarding
TMHL's assessment of compliance with the Servicing Criteria during the
immediately preceding calendar year, as required under Rules 13a-18 and 15d-18
of the Exchange Act and Item 1122 of Regulation AB. Such report shall be

Master Servicer concurrently with the execution of this Amendment;

     (B) deliver to the Master Servicer and any Depositor a report of a
registered public accounting firm that attests to, and reports on, the

paragraph. Such attestation shall be in accordance with Rules 1-02(a)(3) and
2-02(g) of Regulation S-X under the Securities Act and the Exchange Act;

     (C) cause each Subservicer, and each Subcontractor determined by TMHL
pursuant to Section 2.01(b)(ii) to be "participating in the servicing function"

                                       -7-

assessment of compliance and accountants' attestation as and when provided in
paragraphs (ii) and (iii) of this Section; and

     (D) deliver (and cause each Subservicer and Subcontractor described in
clause (C) above to deliver) to the Depositor, the Master Servicer and any other
Person that will be responsible for signing the certification (a "Sarbanes
Certification") required by Rules 13a-14(d) and 15d-14(d) under the Exchange Act

hereto as Exhibit 1.

     TMHL acknowledges that the parties identified in clause (ii)(D) above may
rely on the certification provided by TMHL pursuant to such clause in signing a
Sarbanes Certification and filing such with the Commission. The Master Servicer
or Depositor will not request delivery of a certification under clause (ii)(D)
above unless a Depositor is required under the Exchange Act to file an annual
report on Form 10-K with respect to an issuing entity whose asset pool includes
Mortgage Loans.

Criteria other than those specified by TMHL pursuant to Section 3.

Sarbanes Certifying Party shall be an express third party beneficiary of the

Agreement shall remain in full force and effect. All references to the Servicing
Agreement in any other document or instrument shall be deemed to mean such

     WHEREAS, TMHL from time to time may convey certain of the Mortgage Loans,

     WHEREAS, Section 7.04 of the Servicing Agreement permits the Servicer to
enter into sub-servicing agreements on the terms and conditions stated therein;

     WHEREAS, each of the Seller, the Sub-Servicer and the Servicer desires that
the Sub-Servicer sub-service the Securitized Loans for the benefit of the
Servicer, but pursuant to the terms and conditions of the Servicing Agreement
and this Agreement, rather than the terms and

conditions of the Superseded Sub-Servicing Agreement, which is hereby superseded

the receipt and sufficiency of which are hereby acknowledged, and of the mutual
covenants herein contained, the parties hereto hereby agree as follows:

     4. Successor to Servicer. If the Servicer is terminated or resigns under
the terms of the Servicing Agreement, a successor servicer shall be entitled to

however, that this shall not limit the recourse of the Sub-Servicer against the
Servicer for the payment of any termination fees or expenses under any
sub-servicing agreement.

     5. Capitalized Terms. Capitalized terms used and not defined in this
Agreement shall have the meanings assigned to such terms in the Servicing
Agreement, and if not defined therein, with respect to Securitized Loans, in the
related Trust Agreement.

     6. Place of Delivery and Governing Law. This Agreement shall be deemed in

with the Securities Act, the Exchange Act and the rules and regulations of the

required to effect such changes in the Subservicer's obligations as are
necessary to accommodate evolving interpretations of the provisions of
Regulation AB. In connection with any Securitization Transaction, the
Subservicer shall cooperate fully with TMHL to deliver to TMHL (including any of
its assignees or designees), the Master Servicer and any Depositor, any and all
