The Buyer and Seller have agreed, subject to the terms and conditions of this Amendment, that the Existing Repurchase Agreement be amended to reflect certain agreed upon revisions to the terms of the Existing Repurchase Agreement.

Accordingly, the Buyer and Seller hereby agree, in consideration of the mutual promises and mutual obligations set forth herein, that the Existing Repurchase Agreement is hereby amended as follows:

SECTION 1. Definitions. Section 2 of the Existing Repurchase Agreement is hereby amended by:

1.3 deleting the definition of “LTV” in its entirety and replacing it with the following:

“LTV” shall mean (a) with respect to any Mortgage Loan other than a HARP Mortgage Loan or Agency High LTV Mortgage Loan, the ratio of the original outstanding principal amount of the Mortgage Loan to the Appraised Value of the Mortgaged Property at origination, (b) with respect to any HARP Mortgage Loan, the ratio of the original outstanding principal amount of the HARP Mortgage Loan to the Appraised Value of the Mortgaged Property as of the date such Mortgage Loan is funded as a refinanced Mortgage Loan under HARP 2.0 and (c) with respect to any Mortgage Loan that is an Agency High LTV Mortgage Loan, the ratio of the original outstanding principal amount of the Mortgage Loan to the Appraised Value of the Mortgaged Property as of the date such Mortgage Loan is funded as a refinanced Mortgage Loan under the “High LTV Refinance Option” program implemented by Fannie Mae or the “Enhanced Relief Refinance” program implemented by Freddie Mac, as applicable.

1.4 adding the following definitions in their proper alphabetical order:

“Agency High LTV Mortgage Loan” shall mean a Mortgage Loan, which is secured by a first lien, and such Mortgage Loan (a) conforms to the requirements of an Agency for securitization or cash purchase and (b) has a LTV in excess of the amounts for Conforming Mortgage Loans but otherwise meets the requirements of the “High LTV Refinance Option” program implemented by Fannie Mae or the “Enhanced Relief Refinance” program implemented by Freddie Mac, as applicable.

“Jumbo High LTV Mortgage Loan” shall mean a Jumbo Mortgage Loan for which the related Mortgaged Property has a LTV in excess of [***] but not greater than [***].

SECTION 2. Representations and Warranties. Schedule 1 to the Existing Repurchase Agreement is hereby amended by deleting paragraph (q) in its entirety and replacing it with the following:

(q) LTV, PMI Policy. Except as approved by one of the Agencies, FHA, VA or HUD, no Conforming Mortgage Loan has an LTV greater than 100%. If required by the applicable Agency, FHA, VA or HUD, the Conforming Mortgage Loan is insured by a PMI Policy. All provisions of any PMI Policy have been and are being complied with, such policy is in full force and effect, and all premiums due thereunder have been paid. No action, inaction, or event has occurred and no state of facts exists that has, or will result in the exclusion from, denial of, or defense to coverage. Any Conforming Mortgage Loan subject to a PMI Policy obligates the Mortgagor thereunder to maintain the PMI Policy and to pay all premiums and charges in connection therewith. The Mortgage Interest Rate for the Conforming Mortgage Loan as set forth on the Mortgage Loan Schedule is net of any such insurance premium. The LTV of any Agency High LTV Mortgage Loan meets the requirements of the “High LTV Refinance Option” program implemented by Fannie Mae or the “Enhanced Relief Refinance” program implemented by Freddie Mac, as applicable.

SECTION 5. Representations and Warranties. Seller hereby represents and warrants to the Buyer that, giving effect to this Amendment, it is in compliance with all the terms and provisions set forth in the Repurchase Agreement on its part to be observed or performed, and

that no Default or Event of Default has occurred or is continuing, and hereby confirms and reaffirms the representations and warranties contained in Section 11 of the Repurchase Agreement.
