ARTICLE I.

AMENDMENTS TO THE TRUST AGREEMENT

Section 1.01 Amendments to Definitions.

(a) The definition of “Interest Remittance Amount” is hereby amended in Article I, Section 1.01 (Definitions) of the Trust Agreement to read in its entirety as follows:

2

“Interest Remittance Amount: With respect to any Distribution Date, an amount equal to (a) the sum of (1) all interest collected (other than Payaheads and Prepayment Premiums) or advanced in respect of Scheduled Payments on the Mortgage Loans during the related Collection Period by the applicable Servicers, the Master Servicer or the Securities Administrator (solely in its capacity as successor master servicer), minus (w) the PMI Insurance Premiums and any state taxes imposed on such premiums, (x) the Servicing Fee and (y) previously unreimbursed Advances due to the Servicers, the Master Servicer or the Securities Administrator (solely in its capacity as successor master servicer) to the extent allocable to interest and the allocable portion of previously unreimbursed Servicing Advances, (2) any amounts actually paid by the Servicers with respect to Prepayment Interest Shortfalls and any Compensating Interest Payments and the related Prepayment Period (or, in the case of Mortgage Loans serviced by Aurora or Xxxxx Fargo, the related Collection Period), (3) the portion of any Purchase Price (or PPTL Purchase Price payable with respect to a First Payment Default Mortgage Loan excluding any PPTL Premium) or Substitution Amount paid during the related Prepayment Period (or, in the case of Mortgage Loans serviced by Aurora or Xxxxx Fargo, the related Collection Period) allocable to interest and (4) all Net Liquidation Proceeds, Insurance Proceeds and any other recoveries collected during the related Prepayment Period (or, in the case of Mortgage Loans serviced by Aurora or Xxxxx Fargo, the related Collection Period), to the extent allocable to interest, as reduced by (b) any other costs, expenses or liabilities reimbursable to the Trustee, the Master Servicer, the Securities Administrator, each Custodian and each Servicer to the extent provided in this Agreement, each Servicing Agreement and each Custodial Agreement; provided, however, that in the case of the Trustee, such reimbursable amounts to the Trustee payable from the Interest Remittance Amount and Principal Remittance Amount may not exceed $200,000 during any Anniversary Year. In the event that the Trustee incurs reimbursable amounts in excess of $200,000, it may seek reimbursement for such amounts in subsequent Anniversary Years, but in no event shall more than $200,000 be reimbursed to the Trustee per Anniversary Year. Notwithstanding the foregoing, costs and expenses incurred by the Trustee pursuant to Section 6.14(a) in connection with any transfer of servicing shall be excluded from the $200,000 per Anniversary Year limit on reimbursable amounts. For the avoidance of doubt, (i) the Interest Remittance Amount available on each Swap Payment Date for distributions to the Swap Account shall be equal to the Interest Remittance Amount on the related Distribution Date and (ii) the Interest Remittance Amount for each Distribution Date shall be calculated without regard to any distributions to the Swap Account on the related Swap Payment Date.

(b) The definition of “PPTL Premium” is hereby added to Article 1, Section 1.01 (Definitions) of the Trust Agreement to read in its entirety as follows:

“PPTL Premium: With respect to any First Payment Default Mortgage Loan, the excess, if any, of the PPTL Purchase Price over the Purchase Price.”

Section 1.02 Amendments to Section 2.05(a).

The first sentence of Section 2.05(a) is hereby amended to read in its entirety as follows:

(a) With respect to any Mortgage Loan repurchased by the Depositor pursuant to this Agreement, by the Seller pursuant to the Mortgage Loan Sale Agreement or by the Transferor pursuant to the applicable Transfer Agreement, the principal portion of the funds (including the related PPTL Purchase Price in the case of a First Payment Default Mortgage Loan excluding any PPTL Premium) received by the Trustee in respect of such repurchase of a Mortgage Loan will be considered a Principal Prepayment and the Purchase Price or PPTL Purchase Price shall be deposited in the Collection Account or a Custodial Account, as applicable.

3

Section 1.03 Amendments to Section 5.02(d)(viii).

Section 5.02(d)(viii) is hereby added to Article V (Distributions to Holders of Certificates) of the Trust Agreement to read in its entirety as follows:

“(viii) an amount equal to the aggregate PPTL Premium during the preceding Prepayment Period (which, for purposes of compliance with the REMIC Provisions, shall be treated as an amount distributed by the Upper-Tier REMIC to Class R Certificates) shall be distributed to the Class X Certificates.”
