For the initial distribution date in April 2007, this rate is expected to be approximately 6.5782%. (17) Interest will accrue on these certificates for each distribution date at the per annum rate described below. For the initial distribution date in April 2007, this rate is expected to be approximately 6.1894% per annum. The pass-through rate for each class of Subordinate Certificates for each Distribution Date will be a per annum rate equal to the weighted average (based on the Group Subordinate Amount for the related loan group or assumed loan group, as applicable) of (i) with respect to loan group 1, the weighted average of the Net Mortgage Interest Rates of the Mortgage Loans in loan group 1, (ii) with respect to loan group 2, the weighted average of the Net Mortgage Interest Rates of the Mortgage Loans in loan group 2, (iii) with respect to Assumed Loan Group 3, 6.000% and (iv) with respect to Assumed Loan Group 4, the weighted average of the Net Mortgage Interest Rates of the Mortgage Loans in loan group 3. For the initial Distribution Date in April 2007, this rate is expected to be approximately 6.1894% per annum. The "Group Subordinate Amount" for any Distribution Date and (a) loan group 1 is the excess of the Pool Principal Balance for loan group 1 over the aggregate Class Balance of the Senior Non-PO Certificates of such group immediately prior to such date, (b) loan group 2 is the excess of the Pool Principal Balance for loan group 2 over the sum of (1) the aggregate Class Balance of the Senior Non-PO Certificates of group 2 immediately prior to such date and (2) the Loan Group 2 Class 4-A-1 Portion immediately prior to such date, (c) Assumed Loan Group 3 is the excess of the Pool Principal Balance (Non-PO Portion) for Assumed Loan Group 3 over the aggregate Class Balance of the Senior Non-PO Certificates of group 3 immediately prior to such date and (d) Assumed Loan Group 4 is the excess of the Pool Principal Balance (Non-PO Portion) for Assumed Loan Group 4 over the Loan Group 3 Class 4-A-1 Portion immediately prior to such date. "Assumed Loan Group 3" represents approximately 86.4254982888% of each group 3 Mortgage Loan. "Assumed Loan Group 4" represents approximately 13.5745017112% of each group 3 Mortgage Loan. Senior Principal Distribution Amount The following paragraphs describe the calculation of distributions on the Certificates, other than the Exchangeable Certificates. In the event that all or a portion of a class of Exchangeable REMIC Certificates is exchanged for a proportionate portion of a class of Exchangeable Certificates in a related Exchangeable Combination, a class of such Exchangeable Certificates entitled to principal will be entitled to a proportionate share of the principal distributions otherwise payable on the class of Exchangeable REMIC Certificates in the order of priority assigned to such class of Exchangeable REMIC Certificates. The allocation of the applicable portion of the related Senior Principal Distribution Amount to a class of Exchangeable REMIC Certificates will be made assuming no exchanges have ever occurred. Amounts distributable to Exchangeable Certificates will be made as described herein. For the Senior Certificates of group 1: On each Distribution Date, the Trustee will distribute an amount equal to the lesser of (a) the Group 1 Senior Principal Distribution Amount for that Distribution Date and (b) the Pool Distribution Amount for group 1 remaining after distributions of interest on the Group 1 Senior Certificates, as principal, to the Class 1-A-1 Certificates until their Class Balance has been reduced to zero. For the Senior Certificates of group 2: On each Distribution Date, the Trustee will distribute an amount equal to the lesser of (a) the Group 2 Senior Principal Distribution Amount for that Distribution Date and (b) the Pool Distribution Amount for group 2 remaining after distributions of interest on the Group 2 Senior Certificates, as principal, concurrently, to the Class 2-A-1 and Class 2-A-2 Certificates, pro rata, until their Class Balances have been reduced to zero. For the Senior Non-PO Certificates of group 3: I. On each Distribution Date occurring prior to the Accretion Termination Date for the 3-A-14 Certificates, the Class 3-A-14 Accrual Distribution Amount will be allocated sequentially, to the Class 3-A-11 and Class 3-A-14 Certificates, in that order, until their Class Balances have been reduced to zero. II. On each Distribution Date, the Trustee will distribute an amount equal to the lesser of (a) the Group 3 Senior Principal Distribution Amount for that Distribution Date and (b) the product of (1) the Pool Distribution Amount for group 3 remaining after distributions of interest on the Group 3 Senior Certificates and (2) a fraction, the numerator of which is the Group 3 Senior Principal Distribution Amount and the denominator of which is the sum of the PO Principal Amount and the Group 3 Senior Principal Distribution Amount, as principal, sequentially, as follows: first, to the Class 3-A-R Certificate, until its Class Balance has been reduced to zero; second, concurrently, to the Class 3-A-1, Class 3-A-2 and Class 3-A-13 Certificates, pro rata, up to the Group 3 Priority Amount for that Distribution Date; third, concurrently, up to the PAC Principal Amount for such Distribution Date, as follows: (A) approximately 89.9996080199%, sequentially, to the Class 3-A-4, Class 3-A-6 and Class 3-A-8 Certificates, in that order, until their Class Balances have been reduced to zero; and (B) approximately 10.0003919801% to the Class 3-A-10 Certificates, until their Class Balance has been reduced to zero; fourth, concurrently, as follows: (A) approximately 51.0906778832%, sequentially, as follows: (i) sequentially, up to the TAC Principal Amount for such Distribution Date, to the Class 3-A-11 and Class 3-A-14 Certificates, in that order, until their Class Balances have been reduced to zero; (ii) to the Class 3-A-15 Certificates, until their Class Balance has been reduced to zero; and (iii) sequentially, to the Class 3-A-11 and Class 3-A-14 Certificates, in that order, until their Class Balances have been reduced to zero; (B) approximately 48.9093221168% to the Class 3-A-16 Certificates, until their Class Balance has been reduced to zero; fifth, concurrently, as follows: (A) approximately 89.9996080199%, sequentially, to the Class 3-A-4, Class 3-A-6 and Class 3-A-8 Certificates, in that order, until their Class Balances have been reduced to zero; and (B) approximately 10.0003919801% to the Class 3-A-10 Certificates, until their Class Balance has been reduced to zero; and sixth, concurrently, to the Class 3-A-1, Class 3-A-2 and Class 3-A-13 Certificates, pro rata, until their Class Balances have been reduced to zero. III. On each Distribution Date occurring prior to the Accretion Termination Date for the 3-A-15 Certificates, the Class 3-A-15 Accrual Distribution Amount will be allocated sequentially, as follows: first, sequentially, up to the TAC Principal Amount for such Distribution Date, to the Class 3-A-11 and Class 3-A-14 Certificates, in that order, until their Class Balances have been reduced to zero; and second, to the Class 3-A-15 Certificates, until their Class Balance has been reduced to zero. For the Senior Certificates of group 4: On each Distribution Date, the Trustee will distribute an amount equal to the lesser of (a) the Group 4 Senior Principal Distribution Amount for that Distribution Date and (b) the Pool Distribution Amount for group 4 remaining after distributions of interest on the Group 4 Senior Certificates will be distributed, as principal, to the Class 4-A-1 Certificates, until their Class Balance has been reduced to zero. The preceding distribution priorities for a group will not apply on any Distribution Date on or after the Senior Credit Support Depletion Date. On each of those Distribution Dates, the amount to be distributed as principal to the Senior Non-PO Certificates of such group will be distributed concurrently, as principal to such classes, pro rata, based on their Class Balances. In the event that all or a portion of a class of Exchangeable REMIC Certificates is exchanged for a proportionate portion of the class of Exchangeable Certificates in the related Exchangeable Combination, the class of such Exchangeable Certificates entitled to principal will be entitled to a proportionate share of the principal distributions on the class of Exchangeable REMIC Certificates in the order of priority assigned to such class of Exchangeable REMIC Certificates. The Yield Maintenance Agreements The Trustee, on behalf of the Issuing Entity, will enter into two separate yield maintenance agreements with the Sponsor, as Counterparty, which will be for the benefit of (i) the Class 3-A-11 Certificates (the "Class 3-A-11 Yield Maintenance Agreement" and (ii) the Class 3-A-16 Certificates (the "Class 3-A-16 Yield Maintenance Agreement," and together with the Class 3-A-11 Yield Maintenance Agreement, the "Yield Maintenance Agreements"). With respect to the Class 3-A-11 Yield Maintenance Agreement , for any Distribution Date prior to and including the Distribution Date in July 2010, if one-month LIBOR, as calculated for the Interest Accrual Period related to such Distribution Date, exceeds 5.40% per annum, the Counterparty will be obligated to pay to the Trustee, for deposit into the Class 3-A-11 Reserve Fund, the Class 3-A-11 Yield Maintenance Agreement Payment. The "Class 3-A-11 Yield Maintenance Agreement Payment" for any Distribution Date will be an amount equal to the product of (a) the amount by which (i) one-month LIBOR exceeds (ii) 5.40%, (b) the lesser of (x) the Class Balance of the Class 3-A-11 Certificates prior to distributions on that Distribution Date and (y) the notional amount set forth for that Distribution Date in the applicable table in Appendix E and (c) one-twelfth. The Counterparty is required to make any Class 3-A-11 Yield Maintenance Agreement Payment on the twenty-third day of each month in which a Distribution Date occurs (or, if not a business day, the immediately preceding business day). With respect to the Class 3-A-16 Yield Maintenance Agreement , for any Distribution Date prior to and including the Distribution Date in July 2010, if one-month LIBOR, as calculated for the Interest Accrual Period related to such Distribution Date, exceeds 5.40% per annum, the Counterparty will be obligated to pay to the Trustee, for deposit into the Class 3-A-16 Reserve Fund, the Class 3-A-16 Yield Maintenance Agreement Payment. The "Class 3-A-16 Yield Maintenance Agreement Payment" for any Distribution Date will be an amount equal to the product of (a) the amount by which (i) the lesser of one-month LIBOR and 8.90% exceeds (ii) 5.40%, (b) the lesser of (x) the Class Balance of the Class 3-A-16 Certificates prior to distributions on that Distribution Date and (y) the notional amount set forth for that Distribution Date in the applicable table in Appendix E and (c) one-twelfth. The Counterparty is required to make any Class 3-A-16 Yield Maintenance Agreement Payment on the twenty-third day of each month in which a Distribution Date occurs (or, if not a business day, the immediately preceding business day). Priority Amount On each Distribution Date prior to the Senior Credit Support Depletion Date, to the extent funds are available, an amount up to the Group 3 Priority Amount for such Distribution Date will be distributed as principal to the Class 3-A-1, Class 3-A-2 and Class 3-A-13 Certificates in accordance with the priorities described above under "-- Senior Principal Distribution Amount." The "Group 3 Priority Amount" for any Distribution Date will be equal to the lesser of (i) the aggregate Class Balance of the Class 3-A-1, Class 3-A-2 and Class 3-A-13 Certificates and (ii) the product of the Non-PO Principal Amount for Assumed Loan Group 3, (b) the Shift Percentage and (c) the Group 3 Priority Percentage. The "Group 3 Priority Percentage" for any Distribution Date will equal (i) the aggregate Class Balance of the Class 3-A-1, Class 3-A-2 and Class 3-A-13 Certificates divided by (ii) the Pool Principal Balance (Non-PO Portion) for Assumed Loan Group 3. The "Shift Percentage" for any Distribution Date will be the percentage indicated below: Distribution Date Occurring In Shift Percentage - ------------------------------------------------ ---------------- April 2007 through March 2012................... 0% April 2012 through March 2013................... 30% April 2013 through March 2014................... 40% April 2014 through March 2015................... 60% April 2015 through March 2016................... 80% April 2016 and thereafter....................... 100% PAC Principal Amount and TAC Principal Amount As used above, the "PAC Principal Amount" for any Distribution Date and the Class 3-A-4, Class 3-A-6, Class 3-A-8 and Class 3-A-10 Certificates (the "PAC Group") means the amount, if any, that would reduce the aggregate Class Balance of the PAC Group to the applicable balance shown in the related table set forth below for that Distribution Date. The "PAC Certificates" consist of the PAC Group and the Class 3-A-23, Class 3-A-24, Class 3-A-25, Class 3-A-26, Class 3-A-27, Class 3-A-28, Class 3-A-29, Class 3-A-30, Class 3-A-31, Class 3-A-32, Class 3-A-33 and Class 3-A-34 Certificates. As used above, the "TAC Principal Amount" for any Distribution Date and for the Class 3-A-11 and Class 3-A-14 Certificates (the "TAC Certificates" or the "TAC Group") means the amount, if any, that would reduce the aggregate Class Balance of the TAC Group to the applicable balance shown in the related table set forth below for that Distribution Date.
