WHEREAS, the Seller and the Servicer agree that the provisions of the SWSA shall apply to the Serviced Mortgage Loans, but only to the extent provided herein and that this Agreement shall govern the Serviced Mortgage Loans for so long as such Serviced Mortgage Loans remain subject to the provisions of the Trust Agreement.

(i) by deleting the first, second, third and fourth sentences of the second paragraph of such section and replacing it with the following:

Consistent with the terms of this Agreement, the Company may waive, modify or vary any term of any Mortgage Loan or consent to the postponement of any such term or in any manner grant indulgence to any Mortgagor if in the Company’s reasonable and prudent determination such waiver, modification, postponement or indulgence is not materially adverse to the Purchaser; provided, however, that unless the Mortgagor is in default with respect to the Mortgage Loan or such default is, in the judgment of the Company, reasonably foreseeable, the Company shall not permit any modification with respect to any Mortgage Loan that would change the Mortgage Interest Rate, 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 Mortgage Loan; provided, further, that the final maturity date on any Mortgage Loan shall not be extended past the Final Scheduled Distribution Date (as such term is defined in the Trust Agreement). In the event of such modification, the Company shall calculate the Monthly Payment for such Mortgage Loan based on the modified terms of such Mortgage Loan and shall only be required to make Monthly Advances pursuant to Section 5.03 to the extent of such new Monthly Payment. Without limiting the generality of the foregoing, the Company shall continue, and is hereby authorized and empowered, to execute and deliver on behalf of itself and the Purchasers, all instruments of satisfaction or cancellation, or of partial or full release, discharge and all other comparable instruments, with respect to the Mortgage Loans and with respect to the Mortgaged Properties; provided, further, that upon the full release or discharge, the Company shall notify the related Custodian of the related Mortgage Loan of such full release or discharge.

(ii) by adding the following to the end of the second paragraph of such section:

Promptly after the execution of any assumption, modification, consolidation or extension of any Mortgage Loan, the Company shall forward to the Master Servicer copies of any documents evidencing such assumption, modification, consolidation or extension.

A-7

22. Section 4.04 (Establishment of and Deposits to Custodial Account) is hereby amended as follows:

In the event that the Trust Fund acquires any REO Property in connection with a default or imminent default on a Mortgage Loan, the Company shall dispose of such REO Property not later than the end of the third taxable year after the year of its acquisition by the Trust Fund unless the Company has applied for and received a grant of extension from the Internal Revenue Service to the effect that, under the REMIC Provisions and any relevant proposed legislation and under applicable state law, the applicable Trust REMIC 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 Company has received such an extension, then the Company shall provide a copy of same to the Trustee and Master Servicer and 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 Company has not received such an extension and the Company 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 Trust Fund or if the Company has received such an extension, and the Company is unable to sell the REO Property within the period ending three months before the close of the Extended Period, the Company 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 Company) 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 Trustee shall sign any document prepared by and furnished by the Servicer or take any other action reasonably requested by the Company at the Company’s expense, which would enable the Company, on behalf of the Trust Fund, to request such grant of extension.

A-8

Notwithstanding any other provisions of this Agreement, no REO Property acquired by the Trust Fund shall be rented (or allowed to continue to be rented) or otherwise used by or on behalf of the Trust Fund 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 Trust REMIC 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 Company has agreed to indemnify and hold harmless the Trustee and the Trust Fund with respect to the imposition of any such taxes.

(iii) replacing the word “advances” in the sixth line of the fifth paragraph thereof with “Monthly Advances”, and (iv) adding the following to the end of such Section:

Prior to acceptance by the Company of an offer to sell any REO Property, the Company shall notify the Master Servicer of such offer in writing which notification shall set forth all material terms of said offer (each a “Notice of Sale”). The Master Servicer shall be deemed to have approved the sale of any REO Property unless the Master Servicer notifies the Company in writing, within five (5) days after its receipt of the related Notice of Sale, that it disapproves of the related sale, in which case the Company shall not proceed with such sale.

26. Section 5.01 (Remittances) is hereby amended by replacing the word “second” in the second paragraph of such Section with the word “first”, and is further amended by adding the following after the second paragraph of such Section:

A-15

Within a reasonable period of time, but in no event longer than 30 days of the appointment of a successor entity, the Company 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. The Company shall cooperate with the Trustee and the Master Servicer, as applicable, and such successor in effecting the termination of the Company’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 Company to the Account or any Escrow Account or thereafter received with respect to the Mortgage Loans.

Any successor appointed as provided herein shall execute, acknowledge and deliver to the Trustee, the Company and the Master Servicer an instrument accepting such appointment, wherein the successor shall make an assumption of the due and punctual performance and observance of each covenant and condition to be performed and observed by the Company under this Agreement, whereupon such successor shall become fully vested with all the rights, powers, duties, responsibilities, obligations and liabilities of the Company, with like effect as if originally named as a party to this Agreement. Any termination or resignation of the Company or termination of this Agreement pursuant to Sections 8.04, 10.01, 11.01 or 11.02 shall not affect any claims that the Master Servicer or the Trustee may have against the Company arising out of the Company’s actions or failure to act prior to any such termination or resignation.

The Company shall deliver, within three (3) Business Days of the appointment of a successor Servicer, the funds in the Custodial Account and Escrow Account and all Collateral Files, Credit Files and related documents and statements held by it hereunder to the successor Servicer and the Company shall account for all funds and shall execute and deliver such instruments and do such other things as may reasonably be required to more fully and definitively vest in the successor all such rights, powers, duties, responsibilities, obligations and liabilities of the Company.

Upon a successor’s acceptance of appointment as such, the Company shall notify the Trustee and Master Servicer of such appointment in accordance with the notice procedures set forth herein.

A-16

Except as otherwise provided in this Agreement, all reasonable costs and expenses incurred in connection with any transfer of servicing hereunder (whether as a result of termination or removal of the Company or resignation of the Company or otherwise), including, without limitation, the costs and expenses of the Master Servicer or any other Person in appointing a successor servicer, or of the Master Servicer in assuming the responsibilities of the Company hereunder, or of transferring the Servicing Files and the other necessary data to the successor servicer shall be paid by the terminated, removed or resigning Servicer from its own funds without reimbursement.

40. Section 12.02 (Amendment) is hereby amended and restated in its entirety as follows:

This Agreement may be amended from time to time by written agreement signed by the Company and the Purchaser, with the written consent of the Master Servicer and the Trustee.

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 the Master Servicer and the Trustee receive the benefit of the provisions of this Agreement as intended third party beneficiaries of this Agreement to the extent of such provisions. The Company shall have the same obligations to the Master Servicer and the Trustee as if they were parties to this Agreement, and the Master Servicer and the Trustee shall have the same rights and remedies to enforce the provisions of this Agreement as if they were parties to this Agreement.
