Section 2.3. Recordation of Mortgages and Assignments of Mortgages

With respect to each Mortgage Loan (other than any Mortgage Loan for which a Payoff has been made after the related Cut-off Date and prior to the related Closing Date), in instances where, due to a delay on the part of the recording office, any Recording Documents are not included in the Mortgage File delivered to the Purchaser or its designee on or before the related Closing Date, the Seller shall transmit the Recording Documents to the Purchaser or its designee within 270 days after the related Closing Date.

If such defect would cause the Mortgage Loan to be other than a “qualified mortgage” (as defined in the Code), then notwithstanding the previous sentence, the repurchase or substitution must occur within the sooner of (i) 90 days from the date the defect was discovered by the Seller, the Purchaser or any other party to the related Pooling and Servicing Agreement or (ii) in the case of substitution, two years from the related Closing Date.

If such breach would cause the Mortgage Loan to be other than a “qualified mortgage” (as defined in the Code), then notwithstanding the previous sentence, the repurchase or substitution must occur within the sooner of (i) 90 days from the date the defect was discovered by the Seller, the Purchaser or any other party to the related Pooling and Servicing Agreement or (ii) in the case of substitution, two years from the related Closing Date.

(c) Notwithstanding anything herein to the contrary, promptly upon the earlier of discovery by the Seller or receipt of notice by the Seller of the breach of any representation or warranty of the Seller set forth in Section 3.1(i) if such breach relates to any field on the Mortgage Loan Schedule which identifies any Prepayment Charge or Section 3.1(xxxix), in each case, which materially and adversely affects the interests of the Purchaser or its designee to any Prepayment Charge and such Prepayment Charge has been triggered pursuant to the terms of the related Mortgage Note, the Seller shall pay the amount of the scheduled Prepayment Charge (net of any amount previously collected by or paid to the Purchaser or the Trustee in respect of such Prepayment Charge), and the Seller shall have no obligation to repurchase or substitute for such Mortgage Loan. Payments by the Seller to the Purchaser pursuant to this paragraph shall be made within two Business Days of the earlier of discovery by the Seller or receipt of notice by the Seller of the breach of the related representation or warranty.

(d) It is understood and agreed that the obligations of the Seller set forth in this Section 3.3 constitute the sole remedies available to the Purchaser or its transferee respecting a breach of the representations and warranties by the Seller set forth in Section 3.1.

(e) In addition to such cure, repurchase or substitution obligation, the Seller shall indemnify the Purchaser and hold it harmless against any losses, damages, penalties, fines, forfeitures, reasonable and necessary legal fees and related costs, judgments, and other costs and expenses resulting from the defense of any claim against the Purchaser by a third party resulting from a breach of the representations and warranties made by the Seller in this Article 3.

The headings in this Agreement are for purposes of reference only and shall not limit or otherwise affect the meaning hereof.

Section 7.10. Other Agreements Superseded

This Agreement supersedes all prior agreements and understandings relating to the subject matter hereof.

Section 7.11. Intention of the Parties

It is the intention of the parties that the Purchaser is purchasing, and the Seller is selling, Mortgage Loans and not a debt instrument of the Seller or other security. Accordingly, the parties hereto each intend to treat each of the transactions hereunder for federal income tax purposes as a sale by the Seller, and a purchase by the Purchaser, of Mortgage Loans. The Purchaser shall have the right to review the Mortgage Loans to determine the characteristics of 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 7.12. Nonsolicitation

The Seller covenants and agrees that it will not take any action personally, by telephone, by mail or otherwise, to solicit the prepayment of any Mortgage Loans by the related Mortgagors, in whole or in part following the Closing Date with respect to such Mortgage Loans. Notwithstanding the foregoing, the Seller shall not be prohibited from:

(i) advertising its availability for handling refinancing of mortgage loans if the Mortgage Loans are not specifically targeted;

(ii) promoting terms available for refinancing by sending letters or promotional material to the mortgagors of all the mortgage loans that the Seller or its affiliates owns or services;

(iii) promoting terms available for refinancing by sending letters or promotional material to the mortgagors of all the mortgage loans of a specific type (e.g., conventional fixed-rate or conventional adjustable-rate) that the Seller or its affiliates owns or services;

(iv) promoting terms available for refinancing by sending letters or promotional material to the mortgagors of all the mortgage loans that fall within specific interest rate ranges that the Seller or its affiliates owns or services;

(v) providing payoff information or otherwise cooperating with individual Mortgagors who contact the Seller about prepaying any Mortgage Loan;

(vi) advising individual Mortgagors who contact the Seller about prepaying any Mortgage Loan of refinancing terms or streamlined origination arrangements that are available; or

(vii) engaging in any action to solicit the refinancing of any Mortgage Loan to the extent such action would be permitted under the Xxxxxx Xxx Selling Guide or the Xxxxxx Mae Servicing Guide.

In no event shall the Seller treat mortgage loans that it holds in its own portfolio and the Mortgage Loans as separate classes of mortgages for purposes of advertising the availability of refinancing terms.

Section 7.13. Attorneys’ Fees

If either party retains an attorney to enforce any of the provisions of this Agreement, the prevailing party shall be entitled to reasonable attorneys’ fees from the other party, including, without limitation, fees incurred in arbitration and in trial and appellate courts, fees incurred without suit, and all arbitration, court and accounting costs.

Section 7.14. Security Interest

(a) The parties hereto intend that each transfer of a Mortgage Loan pursuant to this Agreement and the applicable Term Sheet constitute a sale by the Seller to the Purchaser of such Mortgage Loan, including for accounting purposes, and not a secured borrowing. It is, further, not the intention of the parties that any such transfer be deemed the grant of a security interest in any Mortgage Loan by the Seller to the Purchaser to secure a debt or other obligation of the Seller. However, in the event that, notwithstanding the intent of the parties, any Mortgage Loan is held to be the property of the Seller, or if for any other reason this Agreement is held or deemed to create a security interest in any Mortgage Loan, then (a) this Agreement shall constitute a security agreement; and (b) the transfer provided for in this Agreement and the applicable Term Sheet shall be deemed to be a grant by the Seller to the Purchaser of, and the Seller hereby grants to the Purchaser, to secure all of the Seller’s obligations hereunder, a security interest in all of the Seller’s right, title, and interest, whether now owned or hereafter acquired, in, to and under: (i) the Mortgage Loans listed on the Mortgage Loan Schedule to each Term Sheet; (ii) all accounts, chattel paper, deposit accounts, documents, general intangibles, goods, instruments, investment property, letter-of-credit rights, letters of credit, money, and oil, gas, and other minerals, consisting of, arising from, or relating to, any of the foregoing; and (iii) all proceeds of the foregoing. The Purchaser shall have all of the rights of a secured party under the applicable Uniform Commercial Code.

(b) The Seller shall take or cause to be taken such actions and execute such documents, including without limitation the filing of any financing statements, continuation statements, and amendments to financing statements, as are necessary to perfect the Purchaser’s interests in each Mortgage Loan. The Seller shall file such financing statements, continuation statements, and amendments on a timely basis.

(c) No later than ten (10) days following each Closing Date, the Seller shall file in the applicable jurisdictions such UCC financing statements covering the Mortgage Loans sold by the Seller on such Closing Date as are necessary to perfect the Purchaser’s interests in such Mortgage Loans.

Section 7.15. Covenant Not to Place Purchaser or Trust Into Bankruptcy

The Seller covenants that it shall not, until at least one year and one day after all securities issued by any Trust to which the Purchaser has transferred Mortgage Loans have been paid in full, take any action to file an involuntary bankruptcy petition against the Purchaser or any Trust.
