as depositor (the "Depositor"), Wachovia Bank, National Association, as master

servicer (the "Master Servicer"), CWCapital Asset Management LLC, as special

servicer (the "Special Servicer"), and LaSalle Bank National Association, as

trustee (the "Trustee"), pursuant to which the Purchaser will sell the Mortgage

Loans (as defined herein) to a trust fund and certificates representing

ownership interests in the Mortgage Loans will be issued by the trust fund. For

purposes of this Agreement, the term "Mortgage Loans" refers to the mortgage

loans listed on Exhibit A and the term "Mortgaged Properties" refers to the

properties securing such Mortgage Loans.

The Purchaser and the Sellers wish to prescribe the manner of sale

of the Mortgage Loans from the Sellers to the Purchaser and in consideration of

the premises and the mutual agreements hereinafter set forth, agree as follows:

SECTION 1. Sale and Conveyance of Mortgages; Possession of Mortgage

File. Effective as of the Closing Date and upon receipt of the purchase price

set forth in the immediately succeeding paragraph, each Seller does hereby sell,

transfer, assign, set over and convey to the Purchaser, without recourse

(subject to certain agreements regarding servicing as provided in the Pooling

and Servicing Agreement, subservicing agreements permitted thereunder and that

certain Servicing Rights Purchase Agreement, dated as of the Closing Date

between the Master Servicer and the Sellers) all of its right, title, and

interest in and to the related Mortgage Loans described in Exhibit A-1 or

Exhibit A-2, as applicable, including all interest and principal received on or

with respect to the Mortgage Loans after the Cut-off Date (other than payments

of principal and interest first due on the Mortgage Loans on or before the

Cut-off Date). Upon the sale of the related Mortgage Loans, the ownership of

each related Mortgage Note, the Mortgage and the other contents of the related

Mortgage File will be vested in the Purchaser and immediately thereafter the

Trustee and the ownership of records and documents with respect to the related

Mortgage Loan prepared by or which come into the possession of the applicable

Seller (other than the records and documents described in the proviso to Section

3(a) hereof) shall immediately vest in the Purchaser and immediately thereafter

the Trustee. The Sellers' records will accurately reflect the sale of each

Mortgage Loan sold by such Seller to the Purchaser. The Depositor will sell the

Class A-1, Class A-2, Class A-2FL, Class A-3, Class A-4, Class A-SB, Class A-1A,

Class X, Class A-M, Class A-J, Class B, Class C, Class D, Class E and Class F

"Underwriters") specified in the underwriting agreement dated June 28, 2007 (the

"Underwriting Agreement") between the Depositor and J.P. Morgan Securities Inc.

("JPMSI") for itself and as representative of the several underwriters

identified therein, and the Depositor will sell the Class G, Class H, Class J,

Class K, Class L, Class M, Class N, Class P, Class Q, Class T and Class NR

initial purchasers (together with the Underwriters, the "Dealers") specified in

the certificate purchase agreement dated June 28, 2007 (the "Certificate

Purchase Agreement"), between the Depositor and JPMSI for itself and as

representative of the initial purchasers identified therein.

The sale and conveyance of the AIGMC Loans and the SOME II Loans are

being conducted on an arms length basis and upon commercially reasonable terms.

As the purchase price for the AIGMC Loans and the SOME II Loans, the Purchaser

shall pay to the Sellers or at the Sellers' direction in immediately available

funds the sum of $115,922,389.69 (which amount is inclusive of accrued interest

and exclusive of AIGMC's and SOME II's pro rata share of the costs set forth in

Section 9 hereof). The purchase and sale of the AIGMC Loans and the SOME II

Loans shall take place on the Closing Date.

SECTION 2. Books and Records; Certain Funds Received After the

Cut-off Date. 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 Trustee in accordance with this Agreement. Any funds due after the

Cut-off Date in connection with a Mortgage Loan received by each Seller shall be

held in trust for the benefit of the Trustee as the owner of such Mortgage Loan

and shall be transferred promptly to the Master Servicer. All scheduled payments

of principal and interest due on or before the Cut-off Date but collected after

the Cut-off Date, and recoveries of principal and interest collected on or

before the Cut-off Date (only in respect of principal and interest on the

Mortgage Loans due on or before the Cut-off Date and principal prepayments

thereon), shall belong to, and shall be promptly remitted to, the related

Seller.

The transfer of each Mortgage Loan shall be reflected on the related

Seller's balance sheets and other financial statements as a sale of such

Mortgage Loan by such Seller to the Purchaser. The Sellers intend to treat the

transfer of each Mortgage Loan to the Purchaser as a sale for tax purposes.

The transfer of each Mortgage Loan shall be reflected on the

Purchaser's balance sheets and other financial statements as a purchase of such

Mortgage Loan by the Purchaser from the applicable Seller. The Purchaser intends

to treat the transfer of each Mortgage Loan from the Sellers as a purchase for

tax purposes.

SECTION 3. Delivery of Mortgage Loan Documents; Additional Costs and

Expenses. (a) The Purchaser hereby directs the Sellers, and the Sellers hereby

agree, upon the transfer of the Mortgage Loans contemplated herein, to deliver

on the Closing Date to the Trustee or a Custodian appointed thereby, all

documents, instruments and agreements required to be delivered by the Purchaser

to the Trustee with respect to the Mortgage Loans sold by such Seller under

Sections 2.01(b) and 2.01(c) of the Pooling and Servicing Agreement, and meeting

all the requirements of such Sections 2.01(b) and 2.01(c), and such other

documents, instruments and agreements as the Purchaser or the Trustee shall

reasonably request. In addition, each Seller agrees to deliver or cause to be

delivered to the Master Servicer, the Servicing File for each Mortgage Loan

transferred by it pursuant to this Agreement; provided that the Sellers shall

not be required to deliver any draft documents, or any attorney client

communications which are privileged communications or constitute legal or other

due diligence analyses, or internal communications of a Seller or its

affiliates, or credit underwriting or other analyses or data.

(b) With respect to the transfer described in Section 1 hereof, if

the Mortgage Loan documents do not require the related Mortgagor to pay any

costs and expenses relating to any modifications to a related letter of credit

which modifications are required to effectuate such transfer (the "Transfer

Modification Costs"), then the related Seller shall pay the Transfer

Modification Costs required to transfer the letter of credit to the Trustee as

described in such Section 1; provided that if the Mortgage Loan documents

require the related Mortgagor to pay any Transfer Modification Costs, such

Transfer Modification Costs shall be an expense of the Mortgagor unless such

Mortgagor fails to pay such Transfer Modification Costs after the Master

Servicer has exercised all remedies available under the applicable Mortgage Loan

documents to collect such Transfer Modification Costs from such Mortgagor, in

which case Master Servicer shall give the related Seller notice of such failure

and the amount of such Transfer Modification costs and the related Seller shall

pay such Transfer Modification Costs.

SECTION 4. Treatment as a Security Agreement. Each Seller,

concurrently with the execution and delivery hereof, has conveyed to the

Purchaser, all of its right, title and interest in and to the related Mortgage

Loans. The parties intend that such conveyance of each Seller's right, title and

interest in and to the related 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 each

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 its right, title and

interest in, to and under the related Mortgage Loans, all payments of principal

or interest on such Mortgage Loans due after the Cut-off Date, all other

payments made in respect of such Mortgage Loans after the Cut-off Date (except

to the extent such payments were due on or before the Cut-off Date) and all

proceeds 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, each Seller consents to the Purchaser hypothecating and transferring such

security interest in favor of the Trustee and transferring the obligation

secured thereby to the Trustee.

SECTION 5. Covenants of the Seller. Each Seller covenants with the

Purchaser as follows:

(a) it shall record or cause a third party to record in the

appropriate public recording office for real property the intermediate

assignments of the applicable Mortgage Loans and the Assignments of Mortgage

from such Seller to the Trustee in connection with the Pooling and Servicing

Agreement. All recording fees relating to the initial recordation of such

intermediate assignments and Assignments of Mortgage shall be paid by the

related Seller;

(b) it shall take any action reasonably required by the Purchaser,

the Trustee or the Master Servicer, in order to assist and facilitate in the

transfer of the servicing of the Mortgage Loans to the Master Servicer,

including effectuating the transfer of any letters of credit with respect to any

Mortgage Loan to the Trustee (in care of the Master Servicer) for the benefit of

Certificateholders. Prior to the date that a letter of credit, if any, with

respect to any Mortgage Loan is transferred to the Trustee (in care of the

Master Servicer), the related Seller will cooperate with the reasonable requests

of the Master Servicer or Special Servicer, as applicable, in connection with

effectuating a draw under such letter of credit as required under the terms of

the related Mortgage Loan documents;

(c) if, during such period of time after the first date of the

public offering of the Offered Certificates as in the opinion of counsel for the

Underwriters, a prospectus relating to the Offered Certificates is required by

applicable law to be delivered in connection with sales thereof by an

Underwriter or a Dealer, any event shall occur as a result of which it is

necessary to amend or supplement the Prospectus Supplement, including Annexes

A-1, A-2, A-3 and B thereto and the Diskette included therewith, with respect to

any information relating to the Mortgage Loans or the related Seller, in order

to make the statements therein, in the light of the circumstances when the

Prospectus Supplement is delivered to a purchaser, not misleading, or if it is

necessary to amend or supplement the Prospectus Supplement, including Annexes

A-1, A-2, A-3 and B thereto and the Diskette included therewith, with respect to

any information relating to the Mortgage Loans or the related Seller, to comply

with applicable law, such Seller shall do all things necessary to assist the

Depositor to prepare and furnish, at the expense of such Seller (to the extent

that such amendment or supplement relates to such Seller, the Mortgage Loans

sold by such Seller and/or any information relating to the same, as provided by

the Sellers), to the Underwriters such amendments or supplements to the

Prospectus Supplement as may be necessary, so that the statements in the

Prospectus Supplement as so amended or supplemented, including Annexes A-1, A-2,

A-3 and B thereto and the Diskette included therewith, with respect to any

information relating to the Mortgage Loans or the related Seller, will not, in

the light of the circumstances when the Prospectus is so amended or

supplemented, be misleading or so that the Prospectus Supplement, including

Annexes A-1, A-2, A-3 and B thereto and the Diskette included therewith, with

respect to any information relating to the Mortgage Loans or the related Seller,

will comply with applicable law. All terms used in this clause (c) and not

otherwise defined herein shall have the meaning set forth in the Indemnification

Agreement, dated as of June 28, 2007 between the Purchaser and the AIGMC (the

"Indemnification Agreement"); and

requirements of the Exchange Act, the Seller shall provide the Purchaser (or
