NOW THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and of the mutual covenants herein contained, the parties hereto hereby agree as follows:

SECTION 1. Amendment. Effective as of December 21, 2006, the Agreement is hereby amended as follows:

(a) The definition of “Mortgage Loan Schedule” in Article I of the Agreement is hereby amended by deleting clause (33) in its entirety and replacing it with the following: “(33) the product type (e.g., 2/28, 15 year fixed, 30 year fixed, 15/30 balloon, Option ARM, etc.)”.

(b) Article I of the Agreement is hereby amended by adding the following definitions in alphabetical order:

Negative Amortization: The interest portion of the monthly payment which is due, but is unpaid and accrued at the Mortgage Interest Rate on the related Option ARM Mortgage Loan for such month and which, pursuant to the terms of the Mortgage Note, is added to the principal balance of the Option ARM Mortgage Loan.

(d) Section 3.02(m) of the Agreement is hereby amended by deleting the first sentence thereof in its entirety and replacing it with the following:

Each Mortgage Loan with an original principal balance greater than $100,000 is covered by an American Land Title Association (“ALTA”) lender’s title insurance policy, or, if such ALTA lender’s title insurance policy is not available in the applicable jurisdiction, an equivalent lender’s title policy acceptable to an Agency, issued by a title insurer acceptable to an Agency and qualified to do business in the jurisdiction where the related Mortgaged Property is located, insuring (subject to the exceptions contained in Section 3.02(j)(i), (ii) and (iii) above) Countrywide, its successors and assigns as to the first priority lien of the Mortgage in the original principal amount of the Mortgage Loan (including, if the Mortgage Loan is an Option ARM Mortgage Loan which provides for Negative Amortization, the maximum amount of Negative Amortization in accordance with the related Mortgage Note) and, with respect to any Adjustable Rate Mortgage Loan, against any loss by reason of the invalidity or unenforceability of the lien resulting from the provisions of the related Mortgage Note providing for adjustment in the Mortgage Interest Rate and Monthly Payment.

(e) Section 3.02(v) of the Agreement is hereby amended by inserting the following sentence immediately following the first sentence thereof: “With respect to each Option ARM Mortgage Loan which allows Negative Amortization, such Primary Insurance Policy contains provisions to cover the potential Negative Amortization of such Option ARM Mortgage Loan.”

With respect to each Mortgage Loan which is not an Option ARM Mortgage Loan, the Mortgage Note does not permit Negative Amortization. With respect to each Option ARM Mortgage Loan, the related Mortgage Note provides an option for a monthly payment, which is sufficient during the period following each date on which the monthly payment is required to be adjusted pursuant to the related Mortgage Note, to fully amortize the outstanding principal balance as of the first day of such period (including any Negative Amortization) over the then remaining term of such Mortgage Note and to pay interest at the related Mortgage Interest Rate;
