(a) On or prior to each Determination Date, the Servicer shall inform the Trustee in writing with respect to each Mortgage Loan: (1) whether any Realized Loss is a Deficient Valuation or a Debt Service Reduction, (2) of the amount of such loss or Deficient Valuation, or of the terms of such Debt Service Reduction and (3) of the total amount of Realized Losses on the Mortgage Loans in each Loan Group. Based on such information, the Trustee shall determine the total amount of Realized Losses on the Mortgage Loans in each Loan Group with respect to the related Distribution Date. The principal portion of Realized Losses on the Mortgage Loans in a Loan Group with respect to any Distribution Date shall be allocated as follows: (i) the applicable Ratio Strip Percentage of the principal portion of any Realized Loss with respect to a Discount Mortgage Loan in Loan Group 2 or Loan Group 4 shall be allocated to the Class A-P Component of the Related Group until the Component Balance thereof is reduced to zero; and (ii) the applicable Non-Ratio Strip Percentage of the principal portion of any Realized Loss with respect to Certificates by a Mortgage Loan reduction in such Loan Group shall be allocated first to the Subordinate Certificates in reverse order of their respective numerical Class designations (beginning with the Class of Subordinate Certificates then outstanding with the highest numerical Class designation) until the respective Class Certificate Balance of each such Class is reduced to zero, and second to the Senior Certificates of the Related Group, pro rata, on the basis of their respective Class Certificate Balances immediately prior to the related Distribution Date, until the Class Certificate Balances thereof have been reduced of the designated Classes pursuant to zeroSection 5.03(b) below. (b) The Component Balance of the Class A-P PO Component of a each Group shall be reduced on each Distribution Date by the amount, if any, by which the Component Balance of such Class A-P PO Component (after giving effect to the amount to be distributed as a distribution of principal and the allocation of Realized Losses on such Distribution Date) exceeds the Adjusted Pool Amount (Ratio Strip PO Portion) for the Related Loan Group for such Distribution Date. The Class Certificate Balance of the Class of Subordinate 5-PO Certificates then outstanding with the highest numerical Class designation shall be reduced on each Distribution Date by the amount, if any, by which the Class Certificate Balance of such Class (after giving effect to the amount to be distributed as a distribution of principal on such Distribution Date) exceeds the Adjusted Pool Amount (PO Portion) for the Loan Group 5 for such Distribution Date. The Class Certificate Balance of the Class of Class B Certificates then outstanding with the highest numerical Class designation shall be reduced or increased on each Distribution Date by the amount, if any, necessary such that the aggregate of the Class Certificate Balances of all outstanding Classes of Senior Non-PO Certificates and Class B Certificates (after giving effect to the amount to be distributed as a distribution of principal and the allocation of Realized Losses and Ratio Strip the PO Deferred Amounts on such Distribution Date) exceeds equals the sum of the Adjusted Pool Amounts (Non-PO Portion) for all Loan Groups for such Distribution Date. After the Senior Credit Support Depletion Date, the Class Certificate Balances of the Class A Senior Non-PO Certificates of the Related each Group in the aggregate (but not the Component Balance of the Class A-P Component with respect to Group 2 or Group 4) shall be reduced or increased on each Distribution Date by the amount, if any, by which necessary such that the aggregate of the Class Certificate Balances of all outstanding Classes of Class A Senior Non-PO Certificates of such Group (but not the Component Balance of the Class A-P Component of Group 2 or Group 4) (after giving effect to the amount to be distributed as a distribution of principal and the allocation of Realized Losses on such Distribution Date) exceeds the difference between (i) the Adjusted Pool Amount for such Loan Group and Distribution Date and (ii) equals the Adjusted Pool Amount (Ratio Strip Non-PO Portion) for such the Related Loan Group and for such Distribution Date. Any such reduction or increase shall be allocated among the Class A Senior Non-PO Certificates of such Group (but not the Class A-P Component of Group 2 or Group 4) Group, based on the Class Certificate Balances immediately prior to such Distribution DateDate until the Class Certificate Balances thereof have been reduced to zero. (c) Any Realized Loss allocated to a Class of Certificates reduction or any reduction increase in the Class Certificate Balance of a Class of Certificates pursuant to Section 5.03(b) above shall be allocated among the Certificates of such Class in proportion to their respective Percentage Interests. (d) The calculation of the amount to be distributed as principal to any Class of Class B Certificates with respect to a Distribution Date (the "Calculated Principal Distribution") shall be made prior to the allocation of any Realized Losses for such Distribution Date; provided, however, the actual payment of principal to the Classes of Class B Certificates shall be made subsequent to the allocation of Realized Losses for such Distribution Date. In the event that after the allocation of Realized Losses for a Distribution Date, the Calculated Principal Distribution for a Class of Subordinate Class B Certificates is greater than the Class Certificate Balance of such Class, the excess shall be distributed first, sequentially, to the Classes of Subordinate Class B Certificates then outstanding (beginning with the Class of Subordinate Class B Certificates than then outstanding with the lowest numerical designation) until the respective Class Certificate Balance of each such Class is reduced to zero and then to the Class A Senior Non-PO Certificates of such Group, pro rata, in accordance with on the priorities set forth in Section 5.02basis of their respective Class Certificate Balances.

Notwithstanding the foregoing, on any Distribution Date in which the Class 5-A-3 Loss Amount exceeds the Class Certificate Balance of the Class 5-A-4 Certificates prior to any reduction for the Class 5-A-4 Loss Allocation Amount, such excess will be distributed in reduction of the Class Certificate Balance of the Class 5-A-3 Certificates. Any increase in Class Certificate Balance allocated to the Class 5-A-3 Certificates pursuant to Section 5.03(b) will instead increase the Class Certificate Balance of the Class 5-A-4 Certificates. (f) Notwithstanding any other provision of this Section 5.03, no Class Certificate Balance of a Class will be increased on any Distribution Date such that the Class Certificate Balance of such Class exceeds its Initial Class Certificate Balance less all distributions of principal previously distributed in respect of such Class on prior Distribution Dates (excluding in the case of any Class of Class B Certificates any principal otherwise payable to such Class of Class B Certificates but used to pay any PO Deferred Amount). (g) With respect to any Distribution Date, Realized Losses allocated pursuant to this Section 5.03 will be allocated to each Uncertificated Middle-Tier Interest in an amount equal to the amount allocated to its respective Corresponding Upper-Tier Class, Classes, Component or Components as provided above. Realized Losses allocated pursuant to this Section 5.03 will be allocated to each Uncertificated Lower-Tier Interest as described in Section 5.02(a)) and to each Uncertificated Middle-Tier Interest in an amount equal to the Realized Losses allocated to such Uncertificated Middle-Tier Interest's Corresponding Upper Tier Class, Classes or Component.

Any such reduction or increase shall be allocated among the Class A Senior Certificates of such Group (but not the Class A-P Component of Group 2 or Group 4) based on the Class Certificate Balances immediately prior to such Distribution Date. (c) Any Realized Loss allocated to a Class of Certificates reduction or any reduction increase in the Class Certificate Balance of a Class of Certificates pursuant to Section 5.03(b) above shall be allocated among the Certificates of such Class in proportion to their respective Percentage Interests. (d) The calculation of the amount to be distributed as principal to any Class of Subordinate Certificates with respect to a Distribution Date (the "Calculated Principal Distribution") shall be made prior to the allocation of any Realized Losses for such Distribution Date; provided, however, the actual payment of principal to the Classes of Certificates shall be made subsequent to the allocation of Realized Losses for such Distribution Date. In the event that after the allocation of Realized Losses for a Distribution Date, the Calculated Principal Distribution for a Class of Subordinate Certificates of a Group is greater than the Class Certificate Balance of such Class, the excess shall be distributed first, sequentially, to the Classes of Subordinate Certificates then outstanding of such Group (beginning with the Class of Subordinate Certificates than of such Group then outstanding with the lowest numerical designation) until the respective Class Certificate Balance of each such Class is reduced to zero and then to the Class A Senior Certificates of such the Related Group, pro rata, in accordance with the priorities set forth in Section 5.02. (e) After the Senior Credit Support Depletion Date, on any Distribution Date on which the Class 2-A-9 Loss Allocation Amount is greater than zero, the Class Certificate Balance of the Class 2-A-9 Certificates will be reduced by the Class 2-A-9 Loss Allocation Amount and, notwithstanding Section 5.03(a)(ii) and Section 5.03(b), the Class Certificate Balance of the Class 2-A-8 Certificates will not be reduced by the Class 2-A-9 Loss Allocation Amount. (f) With respect to any Distribution Date, Realized Losses allocated pursuant to this Section 5.03 will be allocated to each Uncertificated Middle-Tier Interest in an amount equal to the amount allocated to its respective Corresponding Upper-Tier Class, Classes, Component or Components as provided above. Realized Losses allocated pursuant to this Section 5.03 will be allocated and then to each Uncertificated Lower-Tier Interest as described in Section 5.02(a). (f) After the Senior Credit Support Depletion Date for Group 3, on any Distribution Date on which the Class 3-A-10 Loss Allocation Amount is greater than zero, the Class Certificate Balance of the Class 3-A-10 Certificates will be reduced by the Class 3-A-10 Loss Allocation Amount and, notwithstanding Section 5.03(b), the Class Certificate Balance of the Class 3-A-6 Certificates will not be reduced by the Class 3-A-10 Loss Allocation Amount. Any increase in the Class Certificate Balance allocated to the Class 3-A-6 Certificates pursuant to Section 5.03(b) will instead increase the Class Certificate Balance of the Class 3-A-10 Certificates. (g) Notwithstanding any other provision of this Section 5.03, no Class Certificate Balance of a Class will be increased on any Distribution Date such that the Class Certificate Balance of such Class exceeds its Initial Class Certificate Balance less all distributions of principal previously distributed in respect of such Class on prior Distribution Dates (excluding in the case of any Class of Class B Certificates any principal otherwise payable to such Class B Certificates but used to pay any Class PO Deferred Amount).

Allocation of Losses. (a) On or prior to each Determination Date, the Servicer shall inform the Trustee in writing with respect to each Mortgage Loan: (1) whether any Realized Loss is a Deficient Valuation or a Debt Service Reduction, (2) of the amount of such loss or Deficient Valuation, or of the terms of such Debt Service Reduction and (3) of the total amount of Realized Losses on the Mortgage Loans in each Loan Group. Based on such information, the Trustee shall determine the total amount of Realized Losses on the Mortgage Loans in each Loan Group with respect to the related Distribution Date. The principal portion of Realized Losses on the Mortgage Loans in a Loan Group with respect to any Distribution Date shall be allocated as follows: (i) the applicable Ratio Strip Percentage of the principal portion of any Realized Loss with respect to a Discount Mortgage Loan in Loan Group 2 or Loan Group 4 shall be allocated to the Class A-P Component of the Related Group until the Component Balance thereof is reduced to zero; and (ii) the applicable Non-Ratio Strip Percentage of the principal portion of any Realized Loss with respect to Certificates by a Mortgage Loan reduction in such Loan Group shall be allocated first to the Subordinate Certificates in reverse order of their respective numerical Class designations (beginning with the Class of Subordinate Certificates then outstanding with the highest numerical Class designation) until the respective Class Certificate Balance of each such Class is reduced to zero, and second to the Senior Certificates of the Related Group, pro rata, on the basis of their respective Class Certificate Balances immediately prior to the related Distribution Date, until the Class Certificate Balances thereof have been reduced of the designated Classes pursuant to zerothe operation of Section 5.03(b). (b) The Component Balance of the Class A-P PO Component of a Group shall be reduced on each Distribution Date by the amount, if any, by which the Component Balance of such Class A-P PO Component (after giving effect to the amount to be distributed as a distribution of principal and the allocation of Realized Losses on such Distribution Date) exceeds the Adjusted Pool Amount (Ratio Strip PO Portion) for the Related Loan Group for such Distribution Date. The Class Certificate Balance of the Class of Subordinate 1-B Certificates then outstanding with the highest numerical Class designation shall be reduced or increased on each Distribution Date by the amount, if any, by which necessary such that the aggregate of the Class Certificate Balances of all outstanding Classes of Group 1 Senior Certificates (after giving effect to the amount to be distributed as a distribution of principal and the allocation of Realized Losses and Ratio Strip Deferred Amounts on such Distribution Date) exceeds the sum of the Adjusted Pool Amounts for such Distribution Date. After the Senior Credit Support Depletion Date, the Class Certificate Balances of the Class A 1-B Certificates of the Related Group in the aggregate (but not the Component Balance of the Class 1-A-P Component with respect to Group 2 or Group 4) shall be reduced on each Distribution Date by the amount, if any, by which the aggregate of the Class Certificate Balances of all outstanding Classes of Class A Certificates of such Group (but not the Component Balance of the Class A-P Component of Group 2 or Group 4PO Component) (after giving effect to the amount to be distributed as a distribution of principal and the allocation of Realized Losses the Class A-PO Deferred Amounts on such Distribution Date) exceeds the difference between (i) the Adjusted Pool Amount for such Loan Group and Distribution Date and (ii) equals the Adjusted Pool Amount (Ratio Strip Non-PO Portion) for such Loan Group 1 for such Distribution Date. The Class Certificate Balance of the Class of Class X-B Certificates then outstanding with the highest numerical Class designation shall be reduced or increased on each Distribution Date by the amount, if any, necessary such that the aggregate of the Class Certificate Balances of all outstanding Classes of Group 2 Senior Certificates, Group 4 Senior Certificates and Class X-B Certificates (but not the Component Balances of the Class 2-A-PO Component and Class 4-A-PO Component) (after giving effect to the amount to be distributed as a distribution of principal and the allocation of the Class A-PO Deferred Amounts on such Distribution Date) equals the sum of the Adjusted Pool Amounts (Non-PO Portion) for Loan Group 2 and Loan Group 4 for such Distribution Date. The Class Certificate Balance of the Class 3-B Certificates then outstanding with the highest numerical Class designation shall be reduced or increased on each Distribution Date by the amount, if any, necessary such that the aggregate of the Class Certificate Balances of all outstanding Classes of Group 3 Senior Certificates and Class 3-B Certificates (but not the Component Balance of the Class 3-A-PO Component) (after giving effect to the amount to be distributed as a distribution of principal and the allocation of the Class A-PO Deferred Amounts on such Distribution Date) equals the Adjusted Pool Amount (Non-PO Portion) for Loan Group 3 for such Distribution Date. The Class Certificate Balance of the Class 5-B Certificates then outstanding with the highest numerical Class designation shall be reduced or increased on each Distribution Date by the amount, if any, necessary such that the aggregate of the Class Certificate Balances of all outstanding Classes of Group 5 Senior Certificates and Class 5-B Certificates (but not the Component Balance of the Class 5-A-PO Component) (after giving effect to the amount to be distributed as a distribution of principal and the allocation of the Class A-PO Deferred Amounts on such Distribution Date) equals the Adjusted Pool Amount (Non-PO Portion) for Loan Group 5 for such Distribution Date. After the applicable Senior Credit Support Depletion Date, the Class Certificate Balances of the Senior Certificates of each Group in the aggregate shall be reduced or increased on each Distribution Date by the amount, if any, necessary such that the aggregate of the Class Certificate Balances of all outstanding Classes of Senior Certificates of such Group (after giving effect to the amount to be distributed as a distribution of principal on such Distribution Date) equals the Adjusted Pool Amount (Non-PO Portion) for the Related Loan Group for such Distribution Date. Any such reduction or increase shall be allocated among the Class A Senior Certificates of such Group (but not the Class A-P Component of Group 2 or Group 4) Group, based on the Class Certificate Balances immediately prior to such Distribution Date. (c) Any Realized Loss allocated to a Class of Certificates reduction or any reduction increase in the Class Certificate Balance of a Class of Certificates pursuant to Section 5.03(b) above shall be allocated among the Certificates of such Class in proportion to their respective Percentage Interests. (d) The calculation of the amount to be distributed as principal to any Class of Class 1-B Certificates, Class X-B Certificates, Class 3-B Certificates or Class 5-B Certificates with respect to a Distribution Date (the "Calculated Principal Distribution") shall be made prior to the allocation of any Realized Losses for such Distribution Date; provided, however, the actual payment of principal to the Classes of Class 1-B Certificates, Class X-B Certificates, Class 3-B Certificates or Class 5-B Certificates shall be made subsequent to the allocation of Realized Losses for such Distribution Date. In the event that after the allocation of Realized Losses for a Distribution Date, the Calculated Principal Distribution for a Class of Subordinate Class 1-B Certificates, Class X-B Certificates, Class 3-B Certificates or Class 5-B Certificates is greater than the Class Certificate Balance of such Class, the excess shall be distributed first, sequentially, to the Classes of Subordinate Class 1-B Certificates, Class X-B Certificates, Class 3-B Certificates or the Class 5-B Certificates, as the case may be, then outstanding (beginning with the Class of Subordinate Class 1-B Certificates, Class X-B Certificates, Class 3-B Certificates than or Class 5-B Certificates, as the case may be, then outstanding with the lowest numerical designation) until the respective Class Certificate Balance of each such Class is reduced to zero and then to the Group 1 Senior Certificates, in the case of the Class A 1-B Certificates, pro rata, in accordance with the priorities set forth in Section 5.02, the Group 2 Senior Certificates and Group 4 Senior Certificates, in the case of such GroupClass X-B Certificates, pro rata, in accordance with the priorities set forth in Section 5.02, the Group 3 Senior Certificates, in the case of the Class 3-B Certificates, pro rata, in accordance with the priorities set forth in Section 5.02 or the Group 5 Senior Certificates, in the case of the Class 5-B Certificates, pro rata, in accordance with the priorities set forth in Section 5.02.
