(j)           The second and third paragraphs of Section 2.16 of the Servicing Agreement are hereby amended and restated in their entirety as follows:

“With respect to any REO Property, the deed or certificate of sale shall be taken in the name of the Purchaser, or its designee.  The Trustee’s name shall be placed on the title to such REO Property solely as the Trustee hereunder and not in its individual capacity.  The Servicer shall ensure that the title to such REO Property references the Agreement and the Purchaser’s capacity thereunder.  Pursuant to its efforts to sell such REO Property, the Servicer shall either itself or through an agent selected by the Servicer protect and conserve such REO Property in the same manner and to such extent as is customary in the locality where such REO Property is located and may, incident to its conservation and protection of the interests of the Purchaser, or its designee, rent the same, or any part thereof, as the Servicer deems to be in the best interest of the Purchaser, or its designee, for the period prior to the sale of such REO Property.  The Servicer shall prepare for and deliver to the Purchaser, or its designee, a statement with respect to each REO Property that has been rented showing the aggregate rental income received and all expenses incurred in connection with the maintenance of such REO Property at such times as is necessary to enable the Purchaser, or its designee, to comply with the reporting requirements of the REMIC Provisions.  The net monthly rental income, if any, from such REO Property shall be deposited in the Custodial Account no later than the close of business on each Determination Date.  The Servicer shall perform the tax reporting and withholding required by Sections 1445 and 6050J of the Code with respect to foreclosures and abandonments, the tax reporting required by Section 6050H of the Code with respect to the receipt of mortgage interest from individuals and any tax reporting required by Section 6050P of the Code with respect to the cancellation of indebtedness by certain financial entities, by preparing such tax and information returns as may be required, in the form required, and delivering the same to the Purchaser, or its designee, for filing.

In the event that the Purchaser, or its designee, acquires any Mortgaged Property as aforesaid or otherwise in connection with a default or imminent default on a Mortgage Loan, the Servicer shall dispose of such Mortgaged Property as soon as practicable in a manner that maximizes the Liquidation Proceeds thereof, but in no event later than three years after its acquisition by the Purchaser, or its designee.  In that event, the Purchaser, or its designee, shall have been supplied with an Opinion of Counsel to the effect that the holding by the Purchaser, or its designee, of such Mortgaged Property subsequent to a three-year period, if applicable, will not result in the imposition of taxes on “prohibited transactions” of any REMIC as defined in section 860F of the Code or cause any REMIC to fail to qualify as a REMIC at any time, the Purchaser, or its designee, may continue to hold such Mortgaged Property (subject to any conditions contained in such Opinion of Counsel) after the expiration of such three-year period.  Notwithstanding any other provision of this Agreement, no Mortgaged Property acquired by the Purchaser, or its designee, shall be rented (or allowed to continue to be rented) or otherwise used for the production of income by or on behalf of the Purchaser, or its designee, in such a manner or pursuant to any terms that would (i) cause such Mortgaged Property to fail to qualify as “foreclosure property” within the meaning of section 860G(a)(8) of the Code or (ii) subject any REMIC to the imposition of any federal, state or local income taxes on the income earned from such Mortgaged Property under Section 860G(c) of the Code or otherwise, unless the  Servicer has agreed to indemnify and hold harmless the Purchaser, or its designee, with respect to the imposition of any such taxes.”

(k)           The first sentence of Section 2.18 of the Servicing Agreement is hereby amended to replace the words “Business Day of each month” with the words “calendar day of each month (or, if such 10th day is not a Business Day, the following Business Day)”

“Each month, no later than the 10^th calendar day of each month, the Servicer shall furnish to the Master Servicer a remittance report, in the form of Exhibit II hereto (the “Remittance Report”), and such other mortgage loan level data or information as mutually agreed upon by the Servicer and the Master Servicer, in electronic format acceptable to the Master Servicer, in each case with respect to funds being remitted to the Master Servicer on the related Remittance Date.”

(m)           The second paragraph of Section 3.01 of the Servicing Agreement is hereby amended and restated in its entirety as follows:

“With respect to any funds deposited in the Custodial Account after the Business Day on which such deposit was required to be made, the Servicer shall pay to the Purchaser interest on any such late payment at an annual rate equal to the Prime Rate, adjusted as of the date of each change, plus two 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 such Business Day and ending with the Business Day on which such payment is made, both inclusive.  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 Servicer.”

(n)           Section 3.03 of the Servicing Agreement is hereby amended and restated in its entirety as follows:

“Advances by Servicer.  On the Business Day immediately preceding each Remittance Date, the Servicer shall (a) deposit in the Custodial Account from its own funds an amount equal to all Monthly Payments which were due on the Mortgage Loans during the applicable Due Period and which were delinquent at the close of business on the immediately preceding Determination Date or which were deferred pursuant to Section 2.01, (b) cause to be made an appropriate entry in the records of the Custodial Account that amounts held for future distribution have been, as permitted by this Section 3.03, used by the Servicer in discharge of any such advance or (c) make advances in the form of any combination of (a) or (b) aggregating the total amount of advances to be made. The Servicer’s obligation to make such advances as to any Mortgage Loan will continue through the earlier to occur of (a) the last Monthly Payment due prior to the payment in full of the Mortgage Loan or (b) the last Remittance Date prior to the Remittance Date for the distribution of all Liquidation Proceeds and other payments or recoveries (including Insurance Proceeds, and Condemnation Proceeds) with respect to the Mortgage Loan; provided, however, that such obligation shall cease if the Servicer, in its good faith judgment, determines that an advance would not be recoverable pursuant to Section 2.05(ii). The determination by the Servicer that an advance, if made, would be nonrecoverable, shall be evidenced by an Officer’s Certificate of the Servicer, delivered to the Purchaser, which details the reasons for such determination.  To the extent permitted under Section 2.05 hereof, the Servicer shall be entitled to first priority reimbursement for principal and interest advances and for Servicing Advances from recoveries from the related Mortgagor or from all Liquidation Proceeds and other payments or recoveries (including Insurance Proceeds and Condemnation Proceeds) with respect to the related Mortgage Loan.”
