(d)   Authorization; No Breach . The execution and delivery of this Assignment Agreement have been duly authorized by all necessary corporate action on the part of the Assignor; neither the execution and delivery by the Assignor of this Assignment Agreement, nor the consummation by the Assignor of the transactions herein contemplated, nor compliance by the Assignor with the provisions hereof, will conflict with or result in a breach of, or constitute a default under, any of the provisions of the governing documents of the Assignor or any law, governmental rule or regulation or any material judgment, decree or order binding on the Assignor or any of its properties, or any of the provisions of any material indenture, mortgage, deed of trust, contract or other instrument to which the Assignor is a party or by which it is bound.

(i)   HOEPA . No Mortgage Loan is classified as a “high cost” mortgage loan under Section 32 of the Home Ownership and Equity Protection Act of 1994, as amended, and no Mortgage Loan is considered a “high cost” mortgage loan under any applicable federal, state or local predatory or abusive lending law (or a similarly classified loan using different terminology under a law imposing heightened regulatory scrutiny or additional legal liability for residential mortgage loans having high interest rates, points and/or fees). No Transferred Mortgage Loan is a “High Cost Loan” or “Covered Loan,” as applicable, as such terms are defined in the then current Standard & Poor’s LEVELS â Glossary and no Mortgage Loan originated on or after October 1, 2002 through March 6, 2003 is governed by the Georgia Fair Lending Act.

(j)   Bring Down . With respect to the Servicing Agreement, nothing has occurred or failed to occur from and after the closing date set forth in the Servicing Agreement to January 31, 2007, that would cause any of the representations and warranties relating to the applicable Mortgage Loans set forth in Section 3.02 of the Servicing Agreement to be incorrect in any material respects as of the date hereof as if made on the date hereof.

It is understood and agreed that the representations and warranties set forth in this Section 5 shall survive delivery of the respective Mortgage Loan Documents to the WFB Custodian and shall inure to the benefit of the Assignee and its assigns notwithstanding any restrictive or qualified endorsement or assignment. Upon the discovery by the Assignor or the Assignee and its assigns of a breach of the foregoing representations and warranties, the party discovering such breach shall give prompt written notice to the other parties to this Assignment Agreement, and in no event later than two (2) Business Days from the date of such discovery. It is understood and agreed that the obligations of the Assignor set forth in Section 6 to repurchase a Mortgage Loan constitute the sole remedies available to the Assignee and its assigns on their behalf respecting a breach of the representations and warranties contained in this Section 5. It is further understood and agreed that the Assignor shall be deemed not to have made the representations and warranties in this Section 5(k) with respect to, and to the extent of, representations and warranties made, as to the matters covered in this Section 5(k), by the Servicer in the Servicing Agreement (or any officer’s certificate delivered pursuant thereto).

It is understood and agreed that the Assignor has made no representations or warranties to the Assignee other than those contained in this Section 5, and no other affiliate of the Assignor has made any representations or warranties of any kind to the Assignee.

6.   Repurchase of Mortgage Loans . Upon discovery or notice of any breach by the Assignor of any representation, warranty or covenant under this Assignment Agreement that materially and adversely affects the value of any Mortgage Loan or the interest of the Assignee therein (it being understood that any such defect or breach shall be deemed to have materially and adversely affected the value of the related Mortgage Loan or the interest of the Assignee therein if the Assignee incurs a loss as a result of such defect or breach), the Assignee promptly shall request that the Assignor cure such breach and, if the Assignor does not cure such breach in all material respects within 60 days from the date on which it is notified of the breach, the Assignee may enforce the Assignor’s obligation hereunder to purchase such Mortgage Loan from the Assignee at the Purchase Price (as defined in the Trust Agreement). Notwithstanding the foregoing, however, if such breach is a Qualification Defect, such cure or repurchase must take place within 75 days of discovery of such Qualification Defect.

In the event of a repurchase of any Mortgage Loan by the Assignor, the Assignee shall promptly deliver to the As
