  SECOND AMENDED AND RESTATED MORTGAGE LOAN PURCHASE AGREEMENT This is a Second Amended and Restated Master Mortgage Loan Purchase Agreement (the "Agreement"), dated as of May 1, 2006, by and between Bank of America, National Association, having an office at 214 North Tryon Street, Charlotte, North Carolina 28255 (the "Purchaser") and Wells Fargo Bank, N.A., having an office at 1 Home Campus, Des Moines, Iowa 50328-0001 (the "Seller"). WITNESSETH ---------- WHEREAS, the Seller agrees to sell, and the Purchaser agrees to purchase, from time to time certain residential first lien adjustable rate and/or fixed rate mortgage loans (the "Mortgage Loans") on a servicing retained basis as described herein: WHEREAS, the Mortgage Loans shall be delivered as pools of whole loans (each a "Loan Package") on various dates as provided herein (each a "Closing Date"); and WHEREAS, the parties intend hereby to set forth the terms and conditions upon which the proposed Transactions will be effected. NOW THEREFORE, in consideration of the promises and the mutual agreements set forth herein, the parties hereto agree as follows: SECTION 1. All capitalized terms not otherwise defined herein have the respective meanings set forth in the Second Amended and Restated Master Seller's Warranties and Servicing Agreement, dated as of the date herewith (the "Master Seller's Warranties and Servicing Agreement"). SECTION 2. Agreement to Purchase. The Seller agrees to sell, and the Purchaser agrees to purchase from time to time, Mortgage Loans in Loan Packages having aggregate principal balances on the related Cut-off Date in amounts as set forth in the respective Commitment Letters, or in such other amounts as agreed by the Purchaser and the Seller as evidenced by the actual aggregate principal balance of the Mortgage Loans in the related Loan Package accepted by the Purchaser on the related Closing Date. The Mortgage Loans will be delivered pursuant to the Master Seller's Warranties and Servicing Agreement, between the Purchaser and the Seller. SECTION 3. Mortgage Loan Schedule. The Seller will provide the Purchaser with certain information constituting a listing of the Mortgage Loans to be purchased under this Agreement for each Transaction (the "Mortgage Loan Schedule"). Each Mortgage Loan Schedule shall conform to the definition of "Mortgage Loan Schedule" under the Master Seller's Warranties and Servicing Agreement. SECTION 4. Purchase Price. The purchase price for each Loan Package (the "Purchase Price") shall be the percentage of par as stated in the related Commitment Letter, multiplied by the aggregate scheduled principal balance, as of the related Cut-off Date, of the Mortgage Loans in the related Loan Package, after application of scheduled payments of principal for such related  Loan Package due on or before such Cut-off Date whether or not collected. The Purchase Price for a Loan Package may be adjusted as stated in the related Commitment Letter. In addition to the Purchase Price, the Purchaser shall pay to the Seller, at closing, accrued interest on the aggregate scheduled principal amount of the related Mortgage Loans at the weighted average Mortgage Loan Remittance Rate for each Loan Package from the related Cut-off Date through the day prior to the related Closing Date, inclusive. With respect to each Loan Package, the Purchaser shall be entitled to (1) all scheduled principal due after the related Cut-off Date, (2) all other recoveries of principal collected after the related Cut-off Date (provided, however, that all scheduled payments of principal due on or before the related Cut-off Date and collected by the Seller after the related Cut-off Date shall belong to the Seller), (3) all payments of interest on the Mortgage Loans at the Mortgage Loan Remittance Rate (minus that portion of any such payment which is allocable to the period prior to the related Cut-off Date) and (4) all Prepayment Penalties. The principal balance of each Mortgage Loan as of the related Cut-off Date is determined after application of payments of principal due on or before the related Cut-off Date whether or not collected. Therefore, payments of scheduled principal and interest prepaid for a Due Date beyond the related Cut-off Date shall not be applied to the principal balance as of the related Cut-off Date. Such prepaid amounts (minus interest at the Servicing Fee Rate) shall be the property of the Purchaser. The Seller shall deposit any such prepaid amounts into the Custodial Account, which account is established for the benefit of the Purchaser for subsequent remittance by the Seller to the Purchaser. SECTION 5. Examination of Mortgage Files. Prior to the related Closing Date, the Seller shall (a) deliver to the Purchaser in escrow, for examination, the Custodial Mortgage File for each Mortgage Loan, including a copy of the Assignment of Mortgage, pertaining to each Mortgage Loan, or (b) make the Custodial Mortgage Files and the Retained Mortgage Files available to the Purchaser for examination at the Seller's offices or such other location as shall otherwise be agreed upon by the Purchaser and the Seller. Such examination may be made by the Purchaser or by any prospective purchaser of the Mortgage Loans from the Purchaser, at any time before or after such Closing Date upon prior reasonable notice to the Seller. The fact that the Purchaser or any prospective purchaser of the Mortgage Loans has conducted or has failed to conduct any partial or complete examination of the Custodial Mortgage Files and the Retained Mortgage Files shall not affect the Purchaser's (or any of its successor's) rights to demand repurchase, substitution or other relief or remedy as provided under the Master Seller's Warranties and Servicing Agreement. The Purchaser shall cause the Custodian to act as bailee for the sole and exclusive benefit of the Seller pursuant to the Custodial Agreement and act only in accordance with Seller's instructions. Upon the Seller's receipt of the Purchase Price, the Seller shall provide notification to the Custodian to release ownership of the Mortgage Loan Documents specified above to the Purchaser. Such notification shall be in a form of a written notice by facsimile or other electronic media, with a copy sent to the Purchaser. Subsequent to such release, such Mortgage Loan Documents shall be retained by the Custodian for the benefit of the Purchaser. All Mortgage Loan Documents related to Mortgage Loans not purchased by the Purchaser on the 2  Closing Date, shall be maintained by the Custodian for the benefit of the Seller and shall be returned to the Seller within two (2) Business Days after the Closing Date. SECTION 6. Representations, Warranties and Agreements of Seller. The Seller agrees and acknowledges that it shall, as a condition to the consummation of the transactions contemplated hereby, make the representations and warranties specified in Section 3.01 and 3.02 of the Master Seller's Warranties and Servicing Agreement, as of each Closing Date.

At the Purchaser's option, the Closing shall be either: by telephone, confirmed by letter or wire as the parties shall agree; or conducted in person, at such place as the parties shall agree. The closing shall be subject to each of the following conditions: a) all of the representations and warranties of the Seller under this Agreement and under the Master Seller's Warranties and Servicing Agreement shall be true and correct as of such Closing Date and no event shall have occurred which, with notice or the passage of time, would constitute a default under this Agreement or an Event of Default under the Master Seller's Warranties and Servicing Agreement; b) the Purchaser shall have received, or the Purchaser's attorneys shall have received in escrow, all Closing Documents as specified in Section 9 of this Agreement, in such forms as are agreed upon and acceptable to the Purchaser, duly executed by all signatories other than the Purchaser as required pursuant to the respective terms thereof; c) the Seller shall have delivered and released to the Custodian under the Master Seller's Warranties and Servicing Agreement all documents required pursuant to the Master Seller's Warranties and Servicing Agreement; and d) all other terms and conditions of this Agreement and the Master Seller's Warranties and Servicing Agreement shall have been complied with. 4  Subject to the foregoing conditions, the Purchaser shall pay to the Seller on such Closing Date the related Purchase Price, plus accrued interest pursuant to Section 4 of this Agreement, by wire transfer of immediately available funds to the account designated by the Seller.

The Seller shall be responsible for reasonable costs and expenses associated with any preparation and recording of the initial Assignments of Mortgage. All other costs and expenses incurred in connection with the transfer and delivery of the Mortgage Loans, including fees for title policy endorsements and continuations and the Seller's attorney fees, shall be paid by the Seller.

The Seller shall be entitled to servicing fees calculated as provided therein, at the Servicing Fee Rate. SECTION 12. Financial Statements. The Seller understands that in connection with the Purchaser's marketing of the Mortgage Loans, the Purchaser shall make available to prospective purchasers a Consolidated Statement of Operations of the Seller for the most recently completed two fiscal years respecting which such a statement is available, as well as a Consolidated 5  Statement of Condition at the end of the last two fiscal years covered by such Consolidated Statement of Operations. The Purchaser shall also make available any comparable interim statements to the extent any such statements have been prepared by the Seller in a format intended or otherwise suitable for the public at large. The Seller, if it has not already done so, agrees to furnish promptly to the Purchaser copies of the statements specified above.

SECTION 13. Mandatory Delivery. The sale and delivery on each Closing Date of the related Mortgage Loans described on the respective Mortgage Loan Schedules is mandatory, it being specifically understood and agreed that each Mortgage Loan is unique and identifiable on such Closing Date and that an award of money damages would be insufficient to compensate the Purchaser for the losses and damages incurred by the Purchaser (including damages to prospective purchasers of the Mortgage Loans) in the event of the Seller's failure to deliver the Mortgage Loans on or before such Closing Date. All rights and remedies of the Purchaser under this Agreement are distinct from, and cumulative with, any other rights or remedies under this Agreement or afforded by law or equity and all such rights and remedies may be exercised concurrently, independently or successively. SECTION 14. Notices. All demands, notices and communications hereunder shall be in writing and shall be deemed to have been duly given if mailed, by registered or certified mail, return receipt requested, or, if by other means, when received by the other party at the address shown on the first page hereof, or such other address as may hereafter be furnished to the other party by like notice. Any such demand, notice of communication hereunder shall be deemed to have been received on the date delivered to or received at the premises of the addressee (as evidenced, in the case of registered or certified mail, by the date noted on the return receipt). SECTION 15. Severability Clause. Any part, provision, representation or warranty of this Agreement which is prohibited or which is held to be void or unenforceable shall be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof. Any part, provision, representation or warranty of this Agreement which is prohibited or unenforceable or is held to be void or unenforceable in any jurisdiction shall be ineffective, as to such jurisdiction, to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction as to any Mortgage Loan shall not invalidate or render unenforceable such provision in any other jurisdiction. To the extent permitted by applicable law, the parties hereto waive any provision of law which prohibits or renders void or unenforceable any provision hereof. If the invalidity of any part, provision, representation or warranty of this Agreement shall deprive any party of the economic benefit intended to be conferred by this Agreement, the parties shall negotiate, in good-faith, to develop a structure the economic effect of which is as close as possible to the economic effect of this Agreement without regard to such invalidity. 6  SECTION 16. Counterparts. This Agreement may be executed simultaneously in any number of counterparts. Each counterpart shall be deemed to be an original, and all such counterparts shall constitute one and the same instrument. SECTION 17. Place of Delivery and Governing Law. This Agreement shall be deemed in effect when a fully executed counterpart thereof is received by the Purchaser in North Carolina and shall be deemed to have been made in North Carolina. The Agreement shall be construed in accordance with the laws of the State of New York and the obligations, rights and remedies of the parties hereunder shall be determined in accordance with the laws of the State of New York, except to the extent preempted by Federal Law. In the event a claim or controversy arises concerning the interpretation or enforcement of the terms of this Agreement, the Purchaser and the Seller agree that such claim or controversy may be settled by final, binding arbitration if the Purchaser and the Seller, as applicable, consent to such arbitration at the time such claim or controversy arises which consent may be withheld by the Purchaser or the Seller in their sole discretion. Each of the Seller and the Purchaser hereby knowingly, voluntarily and intentionally waives any and all rights it may have to a trial by jury in respect of any litigation based on, or arising out of, under, or in connection with this Agreement, or any other documents and instruments executed in connection herewith, or any course of conduct, course of dealing, statements (whether oral or written), or actions of the Seller or the Purchaser. This provision is a material inducement for the Purchaser to enter into this Agreement. SECTION 18. Further Agreements. The Purchaser and the Seller each agree to execute and deliver to the other such additional documents, instruments or agreements as may be necessary or appropriate to effectuate the purposes of this Agreement. Without limiting the generality of the foregoing, the Seller shall reasonably cooperate with the Purchaser in connection with the initial resales of the Mortgage Loans by the Purchaser. In that connection, the Seller shall provide to the Purchaser: (i) any and all information and appropriate verification of information, whether through letters of its auditors and counsel or otherwise, as the Purchaser shall reasonably request, and (ii) such additional representations, warranties, covenants, opinions of counsel, letters from auditors and certificates of public officials or officers of the Seller as are reasonably believed necessary by the Purchaser in connection with such resales. The requirement of the Seller pursuant to (ii) above shall terminate on the Closing Date, except as provided pursuant to Article IX of the Master Seller's Warranties and Servicing Agreement. Prior to incurring any out-of-pocket expenses pursuant to this paragraph, the Seller shall notify the Purchaser in writing of the estimated amount of such expense. The Purchaser shall reimburse the Seller for any such expense following its receipt of appropriate details thereof. SECTION 19. Intention of the Parties. It is the intention of the parties that the Purchaser is purchasing, and the Seller is selling, an undivided 100% ownership interest in the Mortgage Loans and not a debt instrument of the Seller or another security. Accordingly, the parties hereto each intend to treat the transaction for Federal income tax purposes as a sale by the Seller, and a purchase by the Purchaser, of the Mortgage Loans. The Purchaser shall have the right to review the Mortgage Loans and the related Custodial Mortgage Files to determine the characteristics of 7  the Mortgage Loans which shall affect the Federal income tax consequences of owning the Mortgage Loans and the Seller shall cooperate with all reasonable requests made by the Purchaser in the course of such review. SECTION 20. Successors and Assigns; Assignment of Purchase Agreement. This Agreement shall bind and inure to the benefit and be enforceable by the Seller and the Purchaser and the respective successors and assigns of the Seller and the Purchaser. This Agreement shall not be assigned, pledged or hypothecated by the Seller to a third party without the consent of the Purchaser. SECTION 21. Waivers; Other Agreements. No term or provision of this Agreement may be waived or modified unless such waiver or modification is in writing and signed by the party against whom such waiver or modification is sought to be enforced. SECTION 22. Exhibits. The exhibits to this Agreement are hereby incorporated and made a part hereof and are an integral part of this Agreement. SECTION 23. General Interpretive Principles.
