EXHIBIT A TO AMENDMENT NO. 3

TO MASTER REPURCHASE AGREEMENT

“(i) Valid First or Second Lien. The Mortgage is a valid, subsisting, enforceable and perfected (a) with respect to each first lien Mortgage Loan, first priority lien and first priority security interest, or (b) with respect to each Second Lien Mortgage Loan, second priority lien and second priority security interest, in each case, on the real property included in the Mortgaged Property, including all buildings on the Mortgaged Property and all installations and mechanical, electrical, plumbing, heating and air conditioning systems located in or annexed to such buildings, and all additions, alterations and replacements made at any time with respect to the foregoing. The lien of the Mortgage is subject only to:

(i) the lien of current real property taxes and assessments not yet due and payable;

(ii) covenants, conditions and restrictions, rights of way, easements and other matters of the public record as of the date of recording acceptable to prudent mortgage lending institutions generally and specifically referred to in Buyer’s title insurance policy delivered to the originator of the Mortgage Loan and (a) referred to or otherwise considered in the appraisal made for the originator of the Mortgage Loan or (b) which do not adversely affect the Appraised Value of the Mortgaged Property set forth in such appraisal;

(iii) other matters to which like properties are commonly subject which do not materially interfere with the benefits of the security intended to be provided by the Mortgage or the use, enjoyment, value or marketability of the related Mortgaged Property; and

(iv) with respect to each Mortgage Loan which is a Second Lien Mortgage Loan, a first lien on the Mortgaged Property.

Any security agreement, chattel mortgage or equivalent document related to and delivered in connection with the Mortgage Loan establishes and creates a valid, subsisting and enforceable (a) with respect to each first lien Mortgage Loan, first priority lien and first priority security interest, or (b) with respect to each Second Lien Mortgage Loan, second priority lien and second priority security interest, in each case, on the property described therein and Seller has full right to pledge and assign the same to Buyer. The Mortgaged Property was not, as of the date of origination of the Mortgage Loan, subject to a mortgage, deed of trust, deed to secure debt or other security instrument creating a lien subordinate to the lien of the Mortgage;”

“(n) Title Insurance. The Mortgage Loan is covered by either (i) an attorney’s opinion of title and abstract of title, the form and substance of which is acceptable to prudent mortgage lending institutions making mortgage loans in the area wherein the Mortgaged Property is located or (ii) an ALTA lender’s title insurance policy or other generally acceptable form of policy or insurance acceptable to Fannie Mae or Freddie Mac and each such title insurance policy is issued by a title insurer acceptable to Fannie Mae or Freddie Mac and qualified to do business in the jurisdiction where the Mortgaged Property is located, insuring

Seller, its successors and assigns, as to the first priority lien or second priority lien, as applicable, of the Mortgage, as applicable in the original principal amount of the Mortgage Loan (or to the extent a Mortgage Note provides for negative amortization, the maximum amount of negative amortization in accordance with the Mortgage), subject only to the exceptions contained in clauses (a), (b) and (c), and in the case of adjustable rate Mortgage Loans, against any loss by reason of the invalidity or unenforceability of the lien resulting from the provisions of the Mortgage providing for adjustment to the Mortgage Interest Rate and Monthly Payment. Where required by state law or regulation, the Mortgagor has been given the opportunity to choose the carrier of the required mortgage title insurance. Additionally, such lender’s title insurance policy affirmatively insures ingress and egress and against encroachments by or upon the Mortgaged Property or any interest therein. The title policy does not contain any special exceptions (other than the standard exclusions) for zoning and uses and has been marked to delete the standard survey exception or to replace the standard survey exception with a specific survey reading. Seller, its successors and assigns, are the sole insureds of such lender’s title insurance policy, and such lender’s title insurance policy is valid and remains in full force and effect and will be in force and effect upon the consummation of the transactions contemplated by this Repurchase Agreement. No claims have been made under such lender’s title insurance policy, and no prior holder or servicer of the related Mortgage, including Seller, has done, by act or omission, anything which would impair the coverage of such lender’s title insurance policy, including, without limitation, no unlawful fee, commission, kickback or other unlawful compensation or value of any kind has been or will be received, retained or realized by any attorney, firm or other Person, and no such unlawful items have been received, retained or realized by Seller;”

“(uu) Predatory Lending Regulations; High Cost Loans. No Mortgage Loan (a) is subject to Section 226.32 of Regulation Z or any similar state law (relating to high interest rate credit/lending transactions), or (b) is a High Cost Mortgage Loan. In addition to and notwithstanding anything to the contrary herein, no Mortgage Loan for which the Mortgaged Property is located in New Jersey is a Home Loan as defined in the New Jersey Home Ownership Security Act of 2002 that was made, arranged, or assigned by a person selling either a manufactured home or home improvements to the Mortgaged Property or was made by an originator to whom the Mortgagor was referred by any such Seller.”

“(kkk) Massachusetts Mortgage Loans. No Mortgage Loan is secured by Mortgaged Property in the Commonwealth of Massachusetts with a loan application date on or after November 7, 2004 that refinances a Mortgage Loan that is less than sixty (60) months old, unless such Mortgage Loan (i) is on an investment property, (ii) meets the requirements set forth in the Code of Massachusetts Regulation (“CMR”), 209 CMR 53.04(1)(b), or (iii) meets the requirements set forth in the 209 CMR 53.04(1)(c).”
