Upon discovery by either the Servicer, the Depositor, the Master Servicer or the Trustee of a breach of any of the foregoing representations and warranties which materially and adversely affects the ability of the Servicer to perform its duties and obligations under this Agreement or otherwise materially and adversely affects the value of the Mortgage Loans, the Mortgaged Property or the priority of the security interest on such Mortgaged Property or the interest of the Depositor, Trustee or the Trust Fund, the party discovering such breach shall give prompt written notice to the other.

The Servicer shall be entitled to reimbursement for such advances to the same extent as for all other advances made pursuant to Section 5.03.

Promptly after the execution of any assumption, modification, consolidation or extension of any Mortgage Loan, the Servicer shall forward to the Master Servicer copies of any documents evidencing such assumption, modification, consolidation or extension. Notwithstanding anything to the contrary contained in this Agreement, the Servicer shall not make or permit any modification, waiver or amendment of any term of any Mortgage Loan that would cause any REMIC created under the Trust Agreement to fail to qualify as a REMIC or result in the imposition of any tax under Section 860F(a) or Section 860G(d) of the Code.

32.

Section 4.16 (Title, Management and Disposition of REO Property) is hereby amended by (i) replacing the reference to “one year” in the seventh line of the second paragraph thereof with “three years”, (ii) adding two new paragraphs after the second paragraph thereof to read 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 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 Trust Fund unless the Servicer has applied for and received a grant of extension from the Internal Revenue Service ( and provided a copy of the same to the Master Servicer and the Trustee) 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 Servicer has received such an extension, 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 Trust Fund 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 Trustee shall sign any document or take any other action reasonably requested by the Servicer which would enable the Servicer, on behalf of the Trust Fund, to request such grant of extension.

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 Servicer has agreed to indemnify and hold harmless the Trust Fund with respect to the imposition of any such taxes.

(iii)

deleting the first sentence of the third paragraph thereto, (iv) replacing the word “sentence” with “paragraph” in the seventh line of the third paragraph thereto, (v) replacing the word “advances” in the sixth line of the fifth paragraph thereof with “Monthly Advances,” and (vi) by adding the following to the end of such Section:

Prior to acceptance by the Servicer of an offer to sell any REO Property for a sale price that is less than 90% of the unpaid principal balance of the related Mortgage Loan, the Servicer 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 Servicer in writing, within two (2) Business Days after its receipt of the related Notice of Sale, that it disapproves of the related sale, in which case the Servicer shall not proceed with such sale.

33.

Any successor to the Servicer that is not at that time a Servicer of other mortgage loans for the Trust Fund shall be subject to the approval of the Master Servicer, Xxxxxx Brothers Bank, FSB, the Trustee and each Rating Agency (as such term is defined in the Trust Agreement).

Within a reasonable period of time, but in no event longer than 30 days of 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. The Servicer shall cooperate with the Trustee and the Master Servicer, 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 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 Servicer and the Master Servicer an instrument (i) 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 Servicer under this Agreement, whereupon such successor shall become fully vested with all the rights, powers, duties, responsibilities, obligations and liabilities of the Servicer, with like effect as if originally named as a party to this Agreement. Any termination or resignation of the Servicer 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 Servicer arising out of the Servicer’s actions or failure to act prior to any such termination or resignation.

The Servicer 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 Servicer 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 Servicer.

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

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 Servicer or resignation of the Servicer 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 Servicer 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.
