213742 STARM 2007-1

Master Servicing and Trust Agreement

(i) On each Distribution Date, Realized Losses and Special Losses (other than Excess Special Losses) realized during the prior calendar month shall be allocated to reduce the Class Principal Balances of the related Subordinate Certificates in reverse numerical order, in each case until the Class Principal Balance of each such Class has been reduced to zero. If the Class Principal Balances of the Subordinate Certificates have been reduced to zero, further Realized Losses and Special Losses shall be allocated to the Senior Certificates related to the Loan Group in which such Realized Losses or Special Losses occurred, based on the outstanding Class Principal Balances of such Senior Certificates, in each case until each such Class Principal Balance has been reduced to zero; provided, however, that Realized Losses (other than Excess Special Losses) otherwise allocable (A) to the Class 1A1 Certificates shall first be allocated to the Class 1A2 Certificates, to reduce the Certificate Balance of each such Class until such Certificate Balance has been reduced to zero, and thereafter such Realized Losses shall be allocated to the Class 1A1 Certificates, to reduce the Certificate Balance of such Class until such Certificate Balance has been reduced to zero, (B) to the Class 2A1 Certificates shall first be allocated to the Class 2A2 Certificates, to reduce the Certificate Balance of each such Class until such Certificate Balance has been reduced to zero, and thereafter such Realized Losses shall be allocated to the Class 2A1 Certificates, to reduce the Certificate Balance of such Class until such Certificate Balance has been reduced to zero, (C) to the Class 3A1 and Class 3A2 Certificates shall first be allocated to the Class 3A3 Certificates, to reduce the Certificate Balance of such Class until such Certificate Balance has been reduced to zero, and thereafter such Realized Losses shall be allocated to the Class 3A1 and Class 3A2 Certificates, to reduce the Certificate Balance of such Class until such Certificate Balance has been reduced to zero.

(ii) On any Distribution Date, any Excess Special Losses realized during the prior calendar month shall be allocated, pro rata, to (x) all Classes of Senior Certificates related to the Loan Group in which such losses occurred and (y) the related Subordinate Certificates, based on the aggregate Class Principal Balance of such Senior Certificates and the related Group Subordinate Amount of the related Subordinate Certificates, respectively.

(iii)Whenever Realized Losses, Special Losses or Excess Special Losses are required to be allocated to a Class of Certificates, the Realized Loss, Special Loss or Excess Special Loss, as applicable, shall be allocated to Certificates of such Class of the related Loan Group or Loan Groups, as the case may be, based on their respective outstanding principal amounts.

(b) Interest Shortfall. Notwithstanding anything in the Standard Terms or this Trust Agreement to the contrary, on each Distribution Date, before any distributions are made on the Certificates, any Shortfall with respect to any Mortgage Loan shall be allocated to reduce the Accrued Certificate Interest on each Class of Senior Certificates related to the Loan Group of such Mortgage Loan and each Class of related Subordinate Certificates pro rata, based on the amount of Accrued Certificate Interest otherwise owing to each such Class, in the case of the Senior Certificates, and the related Group Subordinate Amount, in the case of the Subordinate Certificates, pursuant to clause (i) of the definition of Accrued Certificate Interest.

(c) Modification Losses. Notwithstanding anything in the Standard Terms or this Trust Agreement to the contrary, in the event that the Note Rate on a Mortgage Loan is reduced as a result of a modification, waiver or amendment of the terms of such Mortgage Loan, whether agreed to by any Servicer or resulting from a bankruptcy, insolvency or similar proceeding involving the related Borrower, such modification, waiver or amendment shall be disregarded for purposes of calculating the Certificate Rate on any Class of Certificates.

213742 STARM 2007-1

(d) Subsequent Recoveries. With respect to any Subsequent Recoveries received with respect to a Mortgage Loan, such Subsequent Recoveries shall be treated as a principal prepayment. In addition, the Class Principal Balance of each Class of Certificates to which Realized Losses have been allocated shall be increased, sequentially in the order of payment priority, by the amount of Subsequent Recoveries, but not by more than the amount of Realized Losses previously allocated to reduce the Class Principal Balance of such Class.

Section 3.03 Crossover Amounts.

(a) If, on any Distribution Date, the aggregate Class Principal Balance of the Group 1, Group 2 or Group 3 Certificates exceeds the outstanding aggregate principal balance of the Mortgage Loans in the related Loan Group (such class or classes, the related “Affected Senior Certificates”), then future principal payments otherwise allocable to the Subordinate Certificates shall be “crossed over” or used to repay principal of the Affected Senior Certificates by increasing the Senior Principal Distribution Amount for the Loan Group related to the Affected Senior Certificates in an amount equal to the lesser of (i) the aggregate amount of principal otherwise payable to the Subordinate Certificates on such Distribution Date and (ii) the amount required to be paid to the Affected Senior Certificates so that their aggregate Class Principal Balance is equal to the outstanding aggregate principal balance of the Mortgage Loans in the related Loan Group.

(b) In addition, if, as a result of rapid prepayments, the aggregate Class Principal Balance of the Group 1, Group 2 or Group 3 Certificates has been reduced to zero and such Senior Certificates are retired, amounts otherwise distributable as principal on each class of Subordinate Certificates shall instead be distributed as principal to the Senior Certificates related to the other Loan Groups which remain outstanding, until the Class Principal Balances of the Senior Certificates related to such Loan Groups have been reduced to zero. In order for the distribution priority described in the foregoing sentence to apply on any Distribution Date, it must also be true that either (a) the related Subordinate Percentage for that Distribution Date is less than 200% of such Subordinate Percentage as of the Cut-Off Date, or (b) the average outstanding principal balance of the Mortgage Loans in Loan Group 1, Loan Group 2 and Loan Group 3 that are delinquent 60 days or more (including any such Mortgage Loans in foreclosure or bankruptcy and REO properties) during the most recent three calendar months as a percentage of the related Subordinate Percentage is greater than or equal to 50%.

(c) All distributions described in this Section 3.03 shall be made in accordance with the priorities set forth in Section 3.01.
