In the event that the Master Servicer and the Servicer fail to enter into a replacement servicing agreement promptly after the termination of the Trust Fund, the Master Servicer may transfer the servicing of the Mortgage Loans to a third party servicer at its sole discretion; provided that the Mortgage Loans shall be serviced in accordance with the terms of this Agreement until such time the servicing of the Mortgage Loans has been transferred to such third-party servicer.

12. NIMS Insurer. In addition to the terms and conditions set forth in this Agreement, any and all rights of the Master Servicer and Trustee to receive notices from the Servicer pursuant to this Agreement shall hereby be equally granted to the NIMS Insurer.

For any and all obligations of the Servicer to obtain consent from the Master Servicer and the Trustee pursuant to this Agreement, the Servicer must also obtain such consent from the NIMS Insurer. Notwithstanding any other provision in this Agreement, the Trust Fund shall hold harmless and indemnify the Servicer for any failure of the NIMS Insurer to comply with the provisions of this Agreement. Notwithstanding any provision herein to the contrary, the parties to this Agreement agree that it is appropriate, in furtherance of the intent of such parties as set forth herein, that the NIMS Insurer receive the benefit of the provisions of this Agreement as an intended third party beneficiary of this Agreement to the extent of such provisions. The Servicer shall have the same obligations to the NIMS Insurer as if it was a party to this Agreement, and the NIMS Insurer shall have the same rights and remedies to enforce the provisions of this Agreement as if it was a party to this Agreement. The parties hereto agree to cooperate in good faith to amend this Agreement in accordance with the terms hereof to include such other provisions as may be reasonably requested by the NIMS Insurer. Notwithstanding the foregoing, all rights of the NIMS Insurer set forth in this Agreement shall exist only so long as the NIM Securities issued pursuant to the NIMS Transaction remain outstanding or the NIMS Insurer is owed amounts in respect of its guarantee of payment on such NIM Securities.

Any such purchase shall be accomplished by: (A) remittance to the Master Servicer of the Purchase Price (as defined in the Trust Agreement) for the Distressed Mortgage Loan for deposit into the Collection Account established by the Master Servicer pursuant to the Trust Agreement, and (B) the NIMS Insurer’s (i) acknowledgment and agreement to retain Servicer, as the servicer for any such purchased Distressed Mortgage Loan, to service such Distressed Mortgage Loan pursuant to the provisions of the SWSA, and (ii) assumption, for the benefit of the Servicer, the rights and obligations of the Trust Fund as owner of such purchased Distressed Mortgage Loans pursuant to the SWSA. The Trustee (or the Custodian on its behalf) and the Servicer shall immediately effectuate the conveyance of the purchased Distressed Mortgage Loans to the NIMS Insurer exercising the purchase option, including prompt delivery of the Servicing File and all related documentation to the applicable NIMS Insurer. A Distressed Mortgage Loan is as of any Determination Date a Mortgage Loan that is delinquent in payment for a period of ninety (90) days or more, without giving effect to any grace period permitted by the related Mortgage Loan, or for which the Servicer has accepted a deed in lieu of foreclosure.

In such instance, the Trustee shall be deemed to have approved such foreclosure or acceptance of a deed in lieu of foreclosure unless the Securities Administrator notifies the Seller in writing, within two (2) Business Days after its receipt of written notice of the proposed foreclosure or deed in lieu of foreclosure from the Seller, that it disapproves of the related foreclosure or acceptance of a deed in lieu of foreclosure.

Any successor appointed as provided herein shall execute, acknowledge and deliver to the Trustee, the Securities Administrator, the Servicer and the Master Servicer an instrument (i) accepting such appointment, wherein the successor shall make an assumption of the due and punctual performance and observance of each covenant and condition to be performed and observed by the Servicer under this Agreement, whereupon such successor shall become fully vested with all the rights, powers, duties, responsibilities, obligations and liabilities of the Servicer, with like effect as if originally named as a party to this Agreement. Any termination or resignation of the Servicer or termination of this Agreement pursuant to Sections 8.05, 10.01, 11.01 or 11.02 shall not affect any claims that the Master Servicer or the Trustee may have against the Servicer arising out of the Servicer’s actions or failure to act prior to any such termination or resignation.

The Servicer shall deliver within three (3) Business Days of the appointment of a successor servicer the funds in the Custodial Account and Escrow Account and all Mortgage Loan Documents and related documents and statements held by it hereunder to the successor servicer and the Servicer shall account for all funds and shall execute and deliver such instruments and do such other things as may reasonably be required to more fully and definitively vest in the successor all such rights, powers, duties, responsibilities, obligations and liabilities of the Servicer.

Upon a successor’s acceptance of appointment as such, the Servicer shall notify the Trustee and Master Servicer of such appointment in accordance with the notice procedures set forth herein.

Except as otherwise provided in this Agreement, all reasonable costs and expenses incurred in connection with any transfer of servicing hereunder (whether as a result of termination or removal of the Servicer or resignation of the Servicer or otherwise), including, without limitation, the costs and expenses of the Master Servicer or any other Person in appointing a successor servicer, or of the Master Servicer in assuming the responsibilities of the Servicer hereunder, or of transferring the Servicing Files and the other necessary data to the successor servicer shall be paid by the terminated, removed or resigning Servicer from its own funds without reimbursement.
