ARTICLE I

Definitions

Section 1.01

Definitions.

Whenever used in this Agreement or in the Preliminary Statement, the following words and phrases, unless the context otherwise requires, shall have the meanings specified in this Article. Unless otherwise specified, all calculations in respect of interest on the Class A Certificates and Subordinated Certificates shall be made on the basis of the actual number of days elapsed and a 360-day year and all calculations in respect of interest on the Class C Certificates, Class IO Interest, REMIC I Regular Interests, REMIC II Regular Interests, REMIC III Regular Interests and all other calculations of interest described herein shall be made on the basis of a 360-day year consisting of twelve 30-day months. The Class P Certificates and the Residual Certificates are not entitled to distributions in respect of interest and, accordingly, will not accrue interest.

60+ Day Delinquent Loan: As of any day during any calendar month, each Mortgage Loan in foreclosure, all REO Property, each Mortgage Loan for which the Mortgagor has filed for bankruptcy, and each Mortgage Loan with respect to which any portion of a Scheduled Payment is, as of the last day of the Remittance Period before the Remittance Period ending in such calendar month, two months or more past due (without giving effect to any grace period). For instance, in making a determination on the Distribution Date in December (December 25) with respect to a Mortgage Loan whose Scheduled Payment for October is delinquent (and that has no previous Scheduled Payment that is delinquent), that Mortgage Loan would not be a 60+ Day Delinquent Loan because as of the last day of the Remittance Period before the Remittance Period ending in December (which would be the Remittance Period ending in November (on November 1), the Scheduled Payment for October (due October 1) would only be one month past due.

Accrued Certificate Interest Distribution Amount: For any Distribution Date and a Class of Certificates (other than the Class P, Class R and Class C Certificates), the amount of interest accrued during the related Interest Accrual Period at the applicable Pass-Through Rate for such Class on the related Class Certificate Balance immediately before the Distribution Date reduced by any Net Prepayment Interest Shortfalls and Relief Act Interest Shortfalls for such Distribution Date allocated to such Class pursuant to Section 4.04.

Addition Notice: With respect to the transfer of Subsequent Mortgage Loans to the Trust Fund pursuant to Section 2.07, a notice of the Depositor’s designation of the Subsequent Mortgage Loans to be sold to the Trust Fund and the aggregate principal balance of such Subsequent Mortgage Loans as of the related Subsequent Cut-off Date. The Addition Notice shall be given no later than three (3) Business Days prior to the related Subsequent Transfer Date and shall be substantially in the form attached hereto as Exhibit P.

Adjusted Mortgage Rate: As to each Mortgage Loan and at any time, the per annum rate equal to (x) the Mortgage Rate less (y) the Servicing Fee Rate.

Adjustment Date: As to any adjustable-rate Mortgage Loan, the first Due Date on which the related Mortgage Rate adjusts as provided in the related Mortgage Note and each Due Date thereafter on which the Mortgage Rate adjusts as provided in the related Mortgage Note.

Advance: The payment required to be made by the Servicer for any Distribution Date pursuant to Section 4.01, the amount of that payment being equal to the aggregate of payments of principal and interest (net of the Servicing Fee and any net proceeds in the case of any REO Properties) on the Mortgage Loans that were due during the related Remittance Period and not received as of the close of business on the related Determination Date, plus an amount equivalent to interest on each REO Property less the aggregate amount of any delinquent payments that the Servicer has determined would constitute a Nonrecoverable Advance if advanced.

Affected Party: As defined in the Swap Agreement.

Affiliate: With respect to any Person, any other Person controlling, controlled or under common control with such Person. For purposes of this definition, “control” means the power to direct the management and policies of a Person, directly or indirectly, whether through ownership of voting securities, by contract, or otherwise and “controlling” and “controlled” shall have meanings correlative to the foregoing. Affiliates also include any entities consolidated within the requirements of generally accepted accounting principles.

Agreement: This Pooling and Servicing Agreement and all amendments and supplements hereto.

Amount Held for Future Distribution: For any Distribution Date, the aggregate amount held in the Certificate Account at the close of business on the related Determination Date on account of (i) Principal Prepayments received after the end of the related Prepayment Period and Liquidation Proceeds and Subsequent Recoveries on the Mortgage Loans, in each case, received after the end of the preceding calendar month and (ii) all Scheduled Payments on the Mortgage Loans due after the end of the related Remittance Period.

Applied Realized Loss Amount: For any Distribution Date and a Class of Subordinated Certificates, the portion of the excess of the aggregate Class Certificate Balance of the Class A and Subordinated Certificates over the aggregate Stated Principal Balance of all of the Mortgage Loans as of the last day of the preceding Remittance Period allocated to such Class pursuant to Section 4.04.

Appraised Value: With respect to any Mortgaged Property, the value thereof as determined by an independent appraisal made at the time of the origination of the related Mortgage Loan or the sale price, if the appraisal is not available; except that, with respect to any Mortgage Loan that is a purchase money mortgage loan, the lesser of (i) the value thereof as determined by an independent appraisal made at the time of the origination of such Mortgage Loan, if any, and (ii) the sales price of the related Mortgaged Property.
