The Seller further agrees that it will not, and will not permit the Servicer or the Master Servicer to alter the information referenced in this paragraph with respect to any Mortgage Loan during the term of this Agreement unless and until such Mortgage Loan is repurchased in accordance with the terms of this Agreement.

In instances where, for a Mortgage Loan that is not a MERS Mortgage Loan, the original recorded Mortgage is not delivered as provided above, and in instances where intervening assignments called for by clause (v) above are unavailable, the Seller will deliver or cause to be delivered the original recorded Mortgage and intervening assignments to the Indenture Trustee or the Custodian on behalf of the Indenture Trustee promptly upon receipt thereof but in no event later than one year after the Closing Date.

The Seller hereby confirms to the Purchaser that it has caused the portions of the Electronic Ledger relating to the Mortgage Loans to be clearly and unambiguously marked, and has made the appropriate entries in its general accounting records, to indicate that such Mortgage Loans have been transferred to the Indenture Trustee, as designee of the Purchaser, and constitute part of the Trust in accordance with the terms of the trust created hereunder.

(c)    The parties hereto intend that the transactions set forth herein be a sale by the Seller to the Purchaser of all the Seller’s right, title and interest in and to the Mortgage Loans and other property described above and the sale by the Purchaser to the Trust of all the Purchaser’s right, title and interest in and to the Mortgage Loans and other property described above. In the event either transaction set forth herein is deemed not to be a sale, the Seller hereby grants to the Purchaser, and the Purchaser hereby grants to the Indenture Trustee, a security interest in all of its respective right, title and interest in, to and under the Mortgage Loans and other property described above; and this Agreement shall constitute a security agreement under applicable law. The Seller and the Purchaser shall, to the extent consistent with this Agreement, take such actions as may be necessary to ensure that, if this Agreement were deemed to create a security interest in the Mortgage Loans, such security interest would be deemed to be a perfected security interest of first priority under applicable law and will be maintained as such throughout the term of the Agreement.

Except as may otherwise expressly be provided herein, neither the Seller nor the Purchaser shall assign, sell, dispose of or transfer any interest in the Trust or any portion thereof, or permit the Trust or any portion thereof to be subject to any lien, claim, mortgage, security interest, pledge or other encumbrance of, any other Person.

In the event that the parties hereto have failed to transfer the entire legal ownership in and to each Mortgage Loan to the Trust, the parties hereto intend that this document operate to transfer the entire equitable ownership interest in and to each Mortgage Loan to the Trust.

(d)    Except with respect to any MERS Mortgage Loan, within thirty (30) days of the Closing Date, the Seller, at its own expense, shall prepare and send for recording the Assignments of Mortgage in favor of the Indenture Trustee, in the appropriate real property or other records. With respect to any Assignment of Mortgage as to which the related recording information is unavailable within thirty (30) days following the Closing Date, such Assignment of Mortgage shall be submitted for recording within thirty (30) days after receipt of such information but in no event later than one year after the Closing Date. The Indenture Trustee or the Custodian on behalf of the Indenture Trustee shall be required to retain a copy of each Assignment of Mortgage submitted for recording. In the event that any such Assignment of Mortgage is lost or returned unrecorded because of a defect therein, the Seller shall promptly prepare a substitute Assignment of Mortgage or cure such defect, as the case may be, and thereafter the Seller shall be required to submit each such Assignment of Mortgage for recording. Any failure of the Seller to comply with this Section 2.1(d) shall result in the obligation of the Seller to purchase or substitute for the related Mortgage Loans pursuant to the provisions of Section 2.2.

(e)    [Reserved].

(f)    If the Seller is given notice that a Mortgage File is defective or incomplete and if the Seller does not correct or cure such omission or defect within the 90-day period specified in this Section 2.1(f), the Seller shall purchase such Mortgage Loan from the Trust on the Determination Date in the month following the month in which such 90-day period expired at the Purchase Price of such Mortgage Loan. At any time the Seller exercises its option to repurchase any Mortgage Loan pursuant to Section 3.1, the Seller shall notify the Purchaser, the Servicer, the Master Servicer, the Securities Administrator and the Indenture Trustee of any such repurchase no later than five Business Days prior to the Determination Date of the month in which it wishes to repurchase such Mortgage Loans and the Seller shall repurchase such Mortgage Loan from the Trust on such Determination Date. The Purchase Price for any purchased or repurchased Mortgage Loan shall be delivered to the Servicer for deposit in the Collection Account no later than the applicable Determination Date; and, upon receipt by the Indenture Trustee or the Custodian on behalf of the Indenture Trustee of written notification of such deposit signed by a Responsible Officer of the Seller, the Indenture Trustee or the Custodian on behalf of the Indenture Trustee shall, in accordance with Section 3.07 of the Servicing Agreement, release to the Seller the related Mortgage File and the Indenture Trustee or the Custodian shall execute and deliver such instruments of transfer or assignment, in each case without recourse, as shall be necessary to vest in the Seller or its designee any Mortgage Loan released pursuant hereto. It is understood and agreed that the obligation of the Seller to purchase any Mortgage Loan as to which a material defect in or omission of a constituent document exists shall constitute the sole remedy against the Seller respecting such defect or omission available to the Servicer (in its role as such), the Master Servicer, the Noteholders, the Securities Administrator or the Indenture Trustee on behalf of Noteholders. If pursuant to the foregoing provisions the Seller repurchases a Mortgage Loan that is a MERS Mortgage Loan, the Seller shall cause the Servicer, at the Seller’s expense, to either (i) cause MERS to execute and deliver an Assignment of Mortgage in recordable form to transfer the Mortgage from MERS to the Seller and shall cause such Mortgage to be removed from registration on the MERS® System in accordance with MERS’ rules and regulations or (ii) cause MERS to designate on the MERS® System the Seller as the beneficial holder of such Mortgage Loan.

The Seller, promptly following the transfer of (i) a Mortgage Loan from or (ii) an Eligible Substitute Mortgage Loan to the Trust pursuant to this Section 2.1 or Section 3.1, as the case may be, shall amend the Mortgage Loan Schedule, appropriately mark the Electronic Ledger and make appropriate entries in its general account records to reflect such transfer and the addition of any Eligible Substitute Mortgage Loan, if applicable.

Section 2.2    Agreement to Purchase .

The Seller agrees to sell and the Purchaser agrees to purchase, on or before December 28, 2006 (the "Closing Date"), certain fixed-rate and adjustable-rate mortgage loans (the "Mortgage Loans"), having an aggregate principal balance as of the close of business on the Cut-Off Date of $624,998,478 (the "Closing Balance"), after giving effect to all payments due on the Mortgage Loans on or before the Cut-Off Date, whether or not received, including the right to any Prepayment Charges payable by the related Mortgagors in connection with any Principal Prepayments on the Mortgage Loans. The purchase price payable in connection with such sale shall consist of (i) the cash proceeds from the sale of the Notes and (ii) delivery of the Trust Certificates to the Seller.

The Seller and the Purchaser intend that the sale of the Mortgage Loans to the Purchaser, followed by the Purchaser’s sale of the Mortgage Loans to the Issuer, shall be treated for federal, state and local tax purposes as a transfer by the Seller directly to the Issuer (followed by the issuance by the Issuer of Notes that are intended by all parties to such issuance to be treated for federal, state and local tax purposes as indebtedness of the Seller secured by the Mortgage Loans).
