WHEREAS, Section 11.01 of the Pooling and Servicing Agreement provides that the Securities Administrator and the Trustee shall be entitled to receive an Opinion of Counsel to the effect that any such amendment will not result in the imposition of any federal income tax on any REMIC created under the Pooling and Servicing Agreement pursuant to the REMIC Provisions or cause any REMIC to fail to qualify as a REMIC at any time that any Certificates are outstanding;

NOW, THEREFORE, the parties hereto hereby agree as follows:

SECTION 1.  

DEFINED TERMS.

For purposes of this Amendment, unless the context clearly requires otherwise, all capitalized terms which are used but not otherwise defined herein shall have the respective meanings assigned to such terms in the Pooling and Servicing Agreement.

SECTION 2.  

AMENDMENTS.

1.

Section 2.03(a)(ii) is hereby deleted in its entirety and replaced by the following:

Upon discovery by any of the parties hereto or receipt of notice by a Responsible Officer in the Corporate Trust Office of the Trustee of any breach by the Seller of any representation, warranty or covenant made by the Seller in Section 2.06 (in such capacity, the “Representing Party”) in respect of any Mortgage Loan that materially adversely affects the value of such Mortgage Loan or the interest therein of the Certificateholders (in the case of any such representation or warranty made to the knowledge or the best of knowledge of the Representing Party as to which the Representing Party has no knowledge, without regard to the Representing Party’s lack of knowledge with respect to the substance of such representation or warranty being inaccurate at the time it was made), such party or the Trustee shall promptly notify the Representing Party and the Servicer of such breach and cause the applicable Representing Party to cure such breach within 90 days from the date that Representing Party was notified of such breach.  Notwithstanding the foregoing, if applicable, any breach by the Seller of any of the representations or warranties contained in the third paragraph of Section 2.06 shall be deemed to materially and adversely affect the interests of the Certificateholders in that Mortgage Loan. If the applicable Representing Party fails to cure such breach in all material respects during such period, the applicable Representing Party shall repurchase such Mortgage Loan from the Trust Fund at the Purchase Price.  The Purchase Price for the repurchased Mortgage Loan shall be deposited in the Distribution Account, and the Securities Administrator, upon receipt of such deposit, shall release or cause the Custodian to release to the Seller or the Depositor, as the case may be, the related Mortgage File and the Trustee shall execute and deliver such instruments of transfer or assignment, in each case without recourse, (provided, however, that in the instruments of transfer or assignment, the Trustee shall represent and warrant to the Seller or the Depositor, as applicable, that the repurchased Mortgage Loan is free and clear of any encumbrance, equity, lien, pledge, charge, claim or security interest created by the Trustee and its successors, assigns and transferees), as the Seller or the Depositor, as applicable, shall furnish to it and as shall be necessary to vest in the Seller or the Depositor, as the case may be, any Mortgage Loan released pursuant hereto, and the Trustee shall have no further responsibility with regard to such Mortgage File.  In lieu of repurchasing any such Mortgage Loan as provided above, if so provided in the Mortgage Loan Purchase Agreement, the Assignment and Assumption Agreement or this Agreement, the Seller or the Depositor, as applicable, may cause such Mortgage Loan to be removed from the Trust Fund (in which case it shall become a Deleted Mortgage Loan) and substitute one or more Qualified Substitute Mortgage Loans in the manner and subject to the limitations set forth in Section 2.03(c).  It is understood and agreed that the obligation of the Seller or the Depositor, as applicable, to cure or to repurchase (or to substitute for) any Mortgage Loan as to which such a breach has occurred and is continuing shall constitute the sole remedy respecting such breach available to the Trustee on behalf of the Certificateholders.

2.  Section 2.06 of the Pooling and Servicing Agreement is amended by adding the following language after the second paragraph thereof:

The Seller hereby represents, warrants and covenants to the Trustee, the Swap Provider and the Securities Administrator that as of the Cut-Off Date:
