The Mortgage Loan Seller agrees to sell, and the Purchaser agrees to purchase, certain mortgage loans listed in Exhibit A hereto (the “Mortgage Loans”) as described herein. The Purchaser, a Delaware corporation with its principal place of business in Iselin, New Jersey, is a wholly-owned limited-purpose finance subsidiary of JPMorgan Chase & Co. The Purchaser intends to deposit the Mortgage Loans into a trust and sell a series of Multi-Class Mortgage Pass-Through Certificates (the “Certificates”), evidencing interests in the Mortgage Loans under a Pooling and Servicing Agreement to be dated as of July 1, 2007 among the Purchaser, JPMorgan Chase Bank, N.A., as servicer, JPMorgan Chase Bank, N.A., as custodian and The Bank of New York Trust Company, N.A., as trustee (the “Trustee”) and paying agent (the “Paying Agent”), substantially in the form previously delivered by the Purchaser to the Mortgage Loan Seller (the “Pooling and Servicing Agreement”).

Pursuant to the Pooling and Servicing Agreement, the Purchaser will assign all of its right, title and interest in and to the Mortgage Loans to the Trustee for the benefit of the Certificateholders. The Certificates will consist of Class 1-A1, Class 1-A2, Class 1-A3, Class 1-A4, Class 2-AV1, Class 2-AV2, Class 2-AV3, Class 2-F4, Class 2-F5, Class 2-F6 and Class 2-F7 Certificates (the “Class A Certificates”), Class 1-M1, Class 1-M2, Class 1-M3, Class 1-M4, Class 1-M5, Class 1-M6, Class 2-M1, Class 2-M2, Class 2-M3, Class 2-M4, Class 2-M5 and Class 2-M6 Certificates (the “Class M Certificates,” and together with the Class A Certificates and the Class B Certificates, the “Offered Certificates”), the Class 1-B1, Class 1-B2, Class 2-B1 and Class 2-B2 Certificates (collectively, the “Class B Certificates”), the Class 1-CE Certificates and the Class 2-CE Certificates (collectively, the “Class CE Certificates”) and will evidence specified interests in two pools of Mortgage Loans and certain other property held in trust under the Pooling and Servicing Agreement. The Class 1-M Certificates and the Class 1-B Certificates, the aggregate original principal amount of which will initially equal approximately 4.50% and 0.85%, respectively, of the outstanding principal balance of the Pool 1 Mortgage Loans, will be subordinate to the Class 1-A Certificates, the aggregate original principal amount of which will initially equal approximately 93.30% of the outstanding principal balance of the Pool 1 Mortgage Loans. The Class 2-M Certificates and the Class 2-B Certificates, the aggregate original principal amount of which will initially equal approximately 4.20% and 0.85%, respectively, of the outstanding principal balance of the Pool 2 Mortgage Loans, will be subordinate to the Class 2-A Certificates, the aggregate original principal amount of which will initially equal approximately 93.55% of the outstanding principal balance of the Pool 2 Mortgage Loans.

The Purchaser has filed with the Securities and Exchange Commission (the “Commission”) registration statements on Form S-3 relating to the Offered Certificates, and the offering thereof from time to time in accordance with Rule 415 under the Securities Act of 1933 and the rules of the Commission thereunder. The Purchaser has caused a prospectus dated July 13, 2007 as supplemented by a prospectus supplement, dated July 25, 2007 (as supplemented, the “Prospectus”) to be prepared with respect to the sale of the Offered Certificates, copies of which have been delivered to the Mortgage Loan Seller.

Now, therefore, in consideration of the premises and the mutual agreements set forth herein, the parties agree as follows:

ARTICLE 1
SALE AND CONVEYANCE OF MORTGAGE LOANS

SECTION 1.01 Sale and Conveyance of Mortgage; Possession of Mortgage File. The Mortgage Loan Seller does hereby sell, transfer, assign, set over and convey to the Purchaser, without recourse, all right, title, and interest of the Mortgage Loan Seller in and to the Mortgage Loans and each of the documents and records maintained by the Mortgage Loan Seller with respect to the origination or servicing of a particular Mortgage Loan (each, a “Mortgage File”) including all principal and interest due on or with respect to the Mortgage Loans after the Cut-off Date. All documents relating to the Mortgage Loans not delivered to the Purchaser are and shall be held in trust by the Mortgage Loan Seller for the benefit of the Purchaser as the owner thereof or the Purchaser’s assignee or designee and the Mortgage Loan Seller’s possession of the contents of each such document so retained is at the will of the Purchaser or the Purchaser’s assignee or designee and such retention and possession by the Mortgage Loan Seller is in a custodial capacity only. Upon sale of the Mortgage Loans, the ownership of each related Mortgage Note, the Mortgage and the contents of the related Mortgage File will be vested in the Purchaser and the ownership of all records and documents with respect to the related Mortgage Loan prepared by or which come into the possession of the Mortgage Loan Seller shall immediately vest in the Purchaser and shall be retained and maintained, in trust, by the Mortgage Loan Seller at the will of the Purchaser in such custodial capacity only. The Mortgage Loan Seller’s records will accurately reflect the sale of each Mortgage Loan to the Purchaser. The Mortgage Loan Seller shall release its custody of the contents of any Mortgage File only in accordance with written instructions from the Purchaser or the Purchaser’s assignee or designee, except that where such release is required as incidental to a repurchase of any such Mortgage Loan pursuant to Section 1.04 or 2.02 hereof, such written instructions shall not be required. The ownership of each Mortgage Note, the Mortgage and the contents of the related Mortgage File will be vested in the Trustee, as assignee of the Purchaser. The Mortgage Loan Seller shall not take any action inconsistent with such ownership and shall not claim any ownership interest therein. The Mortgage Loan Seller shall respond to any third party inquiries with respect to ownership of the Mortgage Loans by stating that such ownership is held by the Trustee and the Certificateholders.

SECTION 1.02 Books and Records. From and after the sale of the Mortgage Loans to the Purchaser, record title to each Mortgage and the related Mortgage Note shall be transferred to the Purchaser or its assignee in accordance with this Agreement. All rights arising out of the

Mortgage Loans, including, but not limited to, all funds received on or in connection with a Mortgage Loan, shall be received and held by the Mortgage Loan Seller in trust for the benefit of the Purchaser or its assignee as the owner of the Mortgage Loans. The Mortgage Loan Seller shall be responsible for maintaining, and shall maintain, a set of records for each Mortgage Loan which shall be clearly marked to reflect the ownership of each Mortgage Loan by the Purchaser or its assignee pursuant to the Pooling and Servicing Agreement.

SECTION 1.03 Delivery of Mortgage Loan Documents. The Mortgage Loan Seller has delivered or caused to be delivered to the Purchaser or its designee in accordance with the instructions of the Purchaser, each of the documents referred to in Section 2.01 of the Pooling and Servicing Agreement.

If, in connection with any Mortgage Loan, the Mortgage Loan Seller cannot deliver the Mortgage with evidence of recording thereon concurrently with the execution and delivery of this Agreement, or within 120 days thereafter, solely because of a delay caused by the public recording office where such Mortgage has been delivered for recordation, the Mortgage Loan Seller shall deliver or cause to be delivered to the Purchaser or its designee an Officer’s Certificate, with a photocopy of such Mortgage attached thereto, stating that such Mortgage has been delivered to the appropriate public recording official for recordation. The Mortgage Loan Seller shall promptly deliver or cause to be delivered to the Purchaser or its designee such Mortgage with evidence of recording indicated thereon upon receipt thereof from the public recording official. Notwithstanding the above, the Mortgage Loan Seller shall co-operate with the Servicers and use its best efforts to cause each original Mortgage with evidence of recording thereon to be delivered to the Purchaser or its designee within 180 days of the Closing Date.

SECTION 1.04 Review of Mortgage Loans; Repurchase of Mortgage Loans. The Purchaser or its designee shall review the documents delivered pursuant to Section 1.03 or Section 2.03 hereof within 270 days after the Closing Date or the date of substitution, as the case may be, to ascertain that all required documents have been executed and received and that such documents relate to the mortgage loans identified on the Mortgage Loan Schedule. If the Purchaser or its designee discovers that any document or documents constituting a part of a Mortgage File is missing or defective in any material respect, the Purchaser or its designee shall notify the Mortgage Loan Seller promptly (and in any event within no more than five Business Days). The Mortgage Loan Seller shall correct or cure any such omission or defect within 60 days from the date the Mortgage Loan Seller was notified of the omission or defect, and, if the Mortgage Loan Seller does not correct or cure each omission or defect within such period, the Mortgage Loan Seller shall repurchase such Mortgage Loan at the Purchase Price within 90 days of the date the Mortgage Loan Seller was notified of such omission or defect. At the time of such repurchase, the Purchaser or the Trustee, as appropriate, shall, in exchange for a written receipt therefor, release documents in its possession relating to such Mortgage Loan to the Mortgage Loan Seller.

The Mortgage Loan Seller shall repurchase all Mortgage Loans to which an exception was taken in the Exception Report and confirmed to the Company by the Trustee unless such exception is cured to the satisfaction of the Purchaser within five Business Days of the date hereof (or such other period as is agreed by the Purchaser and the Trustee, but not more than 60 days). At the time of such repurchase, the Purchaser or the Trustee, as appropriate, shall, in

exchange for a written receipt therefor, release documents in its possession relating to such Mortgage Loan to the Mortgage Loan Seller.

SECTION 1.05 Treatment as a Security Agreement. The Mortgage Loan Seller, concurrently with the execution and delivery hereof, has conveyed to the Purchaser all of the Mortgage Loan Seller’s right, title and interest in and to the Mortgage Loans. The parties intend that the conveyance of the Mortgage Loan Seller’s right, title and interest in and to the Mortgage Loans pursuant to this Agreement shall constitute a purchase and sale and not a loan. If such conveyance is deemed to be a pledge and not a sale, then the parties also intend and agree that the Mortgage Loan Seller shall be deemed to have granted, and in such event does hereby grant, to the Purchaser a first priority security interest in all of the Mortgage Loan Seller’s right, title and interest in and to the Mortgage Loans, all payments of principal or interest on such Mortgage Loans, all other payments made in respect of such Mortgage Loans, and all proceeds if any thereof, and that this Agreement shall constitute a security agreement under applicable law. If such conveyance is deemed to be a pledge and not a sale, the Purchaser may, to secure the Purchaser’s own borrowings, repledge (i) all or any portion of the Mortgage Loans pledged to the Purchaser and not released from the security interest of this Agreement at the time of such pledge and (ii) all proceeds, products and profits derived from such Mortgage Loans, including, without limitation, to the extent of the Mortgage Loan Seller’s interest therein, all moneys, goods, insurance proceeds and other tangible or intangible property received upon the liquidation or sale thereof or otherwise relating thereto. Such a repledge may be made by the Purchaser with or without a repledge by the Purchaser of its rights under this Agreement, and without further notice to or acknowledgment from the Mortgage Loan Seller. The Mortgage Loan Seller waives, to the extent permitted by applicable law, all claims, causes of action and remedies whether legal or equitable (including any right of set-off) against the Purchaser or any assignee of the Purchaser relating to such action by the Purchaser.

ARTICLE 2
REPRESENTATIONS AND WARRANTIES

SECTION 2.01 Representations and Warranties of the Mortgage Loan Seller. The Mortgage Loan Seller represents and warrants to the Purchaser that, as of the Closing Date, it has made the representations and warranties set forth in Section 3.01 of the Pooling and Servicing Agreement for the benefit of the Purchaser. Such representations and warranties are incorporated by reference in this Section 2.01 hereof, and the Purchaser may rely thereon as if such representations and warranties were fully set forth herein.

It is understood and agreed that the representations and warranties incorporated by reference in this Section 2.01 shall survive the sale of the Mortgage Loans to the Purchaser, the sale and delivery of the Mortgage Loans to the Trust Fund and the issuance, sale and delivery of the Certificates by the Purchaser, shall continue so long as any Class A, Class M, Class B or Class CE Certificate shall remain outstanding or until the Pooling and Servicing Agreement shall have been terminated as therein provided, and shall inure to the benefit of the Purchaser, notwithstanding any restrictive or qualified endorsement on any Mortgage Note or Assignment of Mortgage or the examination of any Mortgage File.

The Mortgage Loan Seller acknowledges that, pursuant to the Pooling and Servicing Agreement, the Purchaser will assign all of its right, title and interest in and to the Mortgage Loans and its right to exercise the remedies created by Sections 1.04 and 2.02 hereof to the Trustee for the benefit of the Certificateholders. The Mortgage Loan Seller agrees that, upon such assignment to the Trustee, the Trustee may enforce directly, without joinder of the Purchaser, the repurchase obligations of the Mortgage Loan Seller set forth in Sections 1.04 and 2.02 hereof with respect to breaches of the representations and warranties set forth in Section 3.01 of the Pooling and Servicing Agreement, or with respect to documentary defects or omissions set forth in Section 2.02 of the Pooling and Servicing Agreement.

SECTION 2.02 Breach of Representations and Warranties; Repurchase of Mortgage Loans. Upon discovery by the Mortgage Loan Seller, the Purchaser or the Trustee of a breach of any of the representations and warranties incorporated by reference in Section 2.01 hereof, irrespective of any limitation in such representation or warranty regarding the knowledge of the Mortgage Loan Seller, which materially and adversely affects the value of the Mortgage Loans or the interests of the Purchaser or the Trustee (or which materially and adversely affects the interests of the Purchaser or the Trustee in the related Mortgage Loan in the case of a representation and warranty relating to a particular Mortgage Loan), the party discovering such breach shall give prompt written notice to the other parties. Within 90 days of its discovery or its receipt of notice of any such breach, the Mortgage Loan Seller shall (i) cure such breach, or (ii) substitute a Mortgage Loan if permitted to do so by the provisions of Section 2.03 below, or (iii) if the breach relates to a particular Mortgage Loan, repurchase such Mortgage Loan from the Trustee or the Purchaser, as appropriate, at a price equal to the Purchase Price, or (iv) if the breach relates to a breach of a representation or warranty regarding the Mortgage Loans as a whole, repurchase Mortgage Loans selected by the Purchaser (or its designee or assignee) such that the representations and warranties with respect to the Mortgage Loans as a whole are materially correct, from the Trustee or the Purchaser, as appropriate, at the Purchase Price therefor, so long as such repurchase is in accordance with the Pooling and Servicing Agreement. Any such repurchase shall be accomplished by payment to the Servicers or deposit in the Certificate Account of the Purchase Price (after deducting therefrom any amounts received in respect of such repurchased Mortgage Loan and being held in the Certificate Account for future distribution).

SECTION 2.03 Option to Substitute. If the Mortgage Loan Seller would otherwise be required to repurchase any Mortgage Loan pursuant to Section 1.04 or 2.02 hereof, the Mortgage Loan Seller may, at its option, but only within less than two years of the Closing Date, remove such deficient Mortgage Loan from the terms of this Agreement and substitute another mortgage loan for such deficient Mortgage Loan, in lieu of repurchasing such deficient Mortgage Loan. Any substitute Mortgage Loan shall (i) have an outstanding principal amount at the time of substitution not in excess of the outstanding principal amount of the deficient Mortgage Loan, (ii) have a Mortgage Rate not less than the Mortgage Rate of the deficient Mortgage Loan, and not more than one percentage point greater than the Mortgage Rate of the deficient Mortgage Loan, (iii) have a remaining term to maturity not later than, and not more than one year less than, the remaining term to maturity of the deficient Mortgage Loan, (iv) be, in the reasonable determination of the related servicer, of the same type, quality and character (including location of the Mortgaged Property) as the deficient Mortgage Loan as if the breach had not occurred, (v) have a Loan-to-Value Ratio at origination not greater than that of the deficient Mortgage Loan,

(vi) be, in the reasonable determination of the Mortgage Loan Seller, in material compliance with the representations and warranties incorporated by reference in Section 2.01 hereof as of the date of substitution and (vii) if the deficient Mortgage Loan for which it is being substituted is not a Balloon Loan, not be a Balloon Loan.

The Mortgage Loan Seller shall amend the Mortgage Loan Schedule to reflect the withdrawal of the deficient Mortgage Loan from this Agreement and the substitution of such substitute Mortgage Loan therefor. Upon such amendment, the Mortgage Loan Seller shall be deemed to have made as to such substitute Mortgage Loan the representations and warranties incorporated by reference in Section 2.01 hereof as of the date of such substitution, which shall continue so long as any Class A, Class M, Class B or Class CE Certificate related to the same Mortgage Pool shall remain outstanding or until the Pooling and Servicing Agreement shall have been terminated as therein provided.
