___________________________

(1)

For each Distribution Date (and the related Accrual Period), the interest rate for the Class LT1-A Interest shall be the Aggregate Net WAC, adjusted for expenses in respect of the Group I Certificate Insurance Policy but determined without regard to the Group I Swap Agreement (the “ Group I REMIC IA WAC”).

(2)

For any Distribution Date (and the related Accrual Period), the interest rate for each of these interests shall be the lesser of (i) the product of (a) the “Swap Fixed Rate (%)” under the Group I Swap Agreement for such Distribution Date, as set forth in Annex V to the Prospectus Supplement, (b) 2, and (c) the quotient of (x) the actual number of days in the related Accrual Period divided by (y) 30 (the “REMIC Swap Rate”), and (ii) the product of (a) the Group I REMIC IA WAC and (b) 2.

(3)

For any Distribution Date (and the related Accrual Period), the interest rate for each of these interests shall be the excess, if any, of (i) the product of (a) the Group I REMIC IA WAC and (b) 2, over (ii) the REMIC Swap Rate for such Distribution Date.

(4)

This interest shall have an initial principal balance equal to the excess of the aggregate Stated Principal Balance of the Group I Mortgage Loans as of the Cut-off Date over the aggregate initial principal balance of each other regular interest in REMIC IA.

(5)

The Class LT1-RA interest shall not have a principal amount and shall not bear interest. The Class LT1-RA interest is hereby designated as the sole class of residual interest in REMIC IA.

On each Distribution Date, the Trust Administrator shall first pay or charge as an expense of REMIC IA all expenses of the Trust Fund relating to the Group I Mortgage Loans for such Distribution Date, other than any Net Swap Payment or Swap Termination Payment required to be made from the Trust Fund.

On each Distribution Date, the Trust Administrator shall distribute the aggregate Group I Interest Remittance Amount (net of expenses described in the preceding paragraph and without regard to any payments related to the Group I Swap Agreement) with respect to each of the REMIC IA Regular Interests based on the above-described interest rates.

On each Distribution Date, the Trust Administrator shall distribute the aggregate Group I Principal Remittance Amount with respect to the REMIC IA Regular Interests, first to the Class LT1-A Interest until its principal balance is reduced to zero, and then sequentially, to the other REMIC IA Regular Interests in ascending order of their numerical class designation, and, with respect to each pair of classes having the same numerical designation, in equal amounts to each such class, until the principal balance of each such class is reduced to zero. All losses on the Group I Mortgage Loans shall be allocated among the REMIC IA Regular Interests in the same manner that principal distributions are allocated.

On each Distribution Date, the Trust Administrator shall distribute an amount equal to the amount then on deposit in the Distribution Account that represents Class I-P Prepayment Charges in respect of the Group I Mortgage Loans to the Class LT1-F120 Interest.

REMIC IIA:

The following table sets forth the designations, principal balances and interest rates for each interest in REMIC IIA, each of which (other than the Class LT2-RA interest) is hereby designated as a regular interest in REMIC IIA (the “REMIC IIA Regular Interests”):

Class Designation	Interest Rate	Initial Principal Balance
LT2-LIBOR 1	(1)	(2)
LT2-A	(1)	(3)
LT2-Swap IO	(4)	(4)
LT2-RA	(5)	(5)

(1)

For each Distribution Date (and the related Accrual Period), the interest rate for each of these interests is a per annum rate equal to the weighted average of the interest rates on the REMIC IA Regular Interests in REMIC IA for such Distribution Date, provided, however, that for any Distribution Date on which the LT2-Swap IO Interest is entitled to a portion of the interest accruals on a REMIC IA Regular Interest having an “F” in its class designation, as described in footnote four below, such weighted average shall be computed by first subjecting the rate on such REMIC IA Regular Interest to a cap equal to the product of (i) two, and (ii) LIBOR (as determined pursuant to the Group I Swap Agreement and adjusted for the applicable day count convention) for such Distribution Date (“Swap LIBOR”) (the “Group I REMIC IIA WAC”).

(2)

This interest shall have an initial principal balance equal to the aggregate Stated Principal Balance of the Group I LIBOR Loans with prepayment penalties as of the Cut-off Date.

(3)

(4)

The Class LT2-Swap IO is an interest only class that does not have a principal balance. For the applicable Distribution Date listed in the first column in the table below, the Class LT2-Swap IO shall be entitled to interest accrued on each REMIC IA Regular Interest listed in the second column in the table below at a per annum rate equal to the excess, if any, of (i) the interest rate for each such REMIC IA Regular Interest for such Distribution Date over (ii) the product of (a) two, and (b) Swap LIBOR for such Distribution Date.

The Class LT2-RA interest shall not have a principal amount and shall not bear interest. The Class LT2-RA interest is hereby designated as the sole class of residual interest in REMIC IIA.

On each Distribution Date, interest distributable in respect of the Regular Interests in REMIC IIA for such Distribution Date shall be distributed to such Regular Interests at the interest rates shown above.

On each Distribution Date, all Realized Losses and the aggregate Group I Principal Remittance Amount with respect to the REMIC IA Regular Interests shall be allocated first to the LT2-LIBOR 1 Interest until its principal balance equals the aggregate Stated Principal Balance of the Group I LIBOR Loans with prepayment penalties and then to the LT2-A Interest, until its class principal balance is reduced to zero.

On each Distribution Date, the Trust Administrator shall distribute the Class I-P Prepayment Charges collected in respect of the Group I Mortgage Loans during the preceding Prepayment Period to the LT2-A Interest.

REMIC IIIA

The following table sets forth the designations, principal balances and interest rates for each interest in REMIC IIIA, each of which (other than the Class LT3-RA interest) is hereby designated as a regular interest in REMIC IIIA (the “REMIC IIIA Regular Interests”):

LT3-LIBOR 2	(1)	(2)
LT3-A	(1)	(3)
LT3-IO 1	(4)	(4)
LT3-Swap IO	(5)	(5)
LT3-RA	(6)	(6)

(1)

This interest rate with respect to any Distribution Date (and the related Accrual Period) for each of these REMIC IIIA Regular Interests is a per annum rate equal to the greater of (i) 0.00% and (ii) the weighted average of the interest rates on the LT2-LIBOR 1 and LT2-A Interests in REMIC IIA, computed after reducing the rate payable on the LT2-LIBOR 1 Interest by 5.500% for each Distribution Date prior to the Distribution Date in December 2016 (the “Group I REMIC IIIA WAC”).

(2)

This interest shall have an initial principal balance equal to $100,000,000.

(3)

(4)

The Class LT3-IO 1 is an interest only class that does not have a principal balance. For each Distribution Date before December 2016, the LT3-IO 1 Interest shall be entitled to interest payable on the LT2-LIBOR 1 Interest in REMIC IIA at a rate equal to the lesser of (i) 5.500% and (ii) the interest rate for the LT2-LIBOR 1 Interest in REMIC IIA.

(5)

The LT3-Swap IO Interest shall not have a principal balance, but shall be entitled to receive, on each Distribution Date, 100% of the interest distributable on the LT2-Swap IO Interest in REMIC IIA.

(6)

copies of the filed UCC assignments or amendments of the security interest referenced in clause (v) above showing an unbroken chain of title from the originator to the Trust, each with evidence of recording thereof, evidencing the interest of the assignee under the Security Agreement and the Assignment of Proprietary Lease;

(G)

an executed assignment of the interest of the originator in the Security Agreement, the Assignment of Proprietary Lease and the Recognition Agreement, showing an unbroken chain of title from the originator to the Trust; and

(H)

for any Cooperative Mortgage Loan that has been modified or amended, the original instrument or instruments effecting such modification or amendment.

Notwithstanding the foregoing, if any Mortgage has been recorded in the name of Mortgage Electronic Registration System, Inc. (“MERS”) or its designee, no assignment of Mortgage in favor of the Trustee will be required to be prepared or delivered and instead, the Master Servicer shall enforce the obligations of the applicable Servicer under its related Servicing Agreement to cause the Trustee to be shown as the owner of the related Mortgage Loan on the records of MERS for the purpose of the system of recording transfers of beneficial ownership of mortgages maintained by MERS.

If in connection with any Mortgage Loan the Depositor cannot deliver (a) the original recorded Mortgage, (b) all interim recorded assignments or (c) the lender’s title policy (together with all riders thereto) satisfying the requirements of clause (b)(i)(B), (C) or (E) above, respectively, concurrently with the execution and delivery hereof because such document or documents have not been returned from the applicable public recording office in the case of clause (b)(i)(B) or (C) above, or because the title policy has not been delivered to either the Custodian or the Depositor by the applicable title insurer in the case of clause (b)(i)(E) above, the Depositor shall promptly deliver to the Custodian, in the case of clause (b)(i)(B) or (C) above, such original Mortgage or such interim assignment, as the case may be, with evidence of recording indicated thereon upon receipt thereof from the public recording office, or a copy thereof, certified, if appropriate, by the relevant recording office, but in no event shall any such delivery of the original Mortgage and each such interim assignment or a copy thereof, certified, if appropriate, by the relevant recording office, be made later than one year following the Closing Date, or, in the case of clause (b)(i)(E) above, no later than 120 days following the Closing Date; provided, however, in the event the Depositor is unable to deliver by such date each Mortgage and each such interim assignment by reason of the fact that any such documents have not been returned by the appropriate recording office, or, in the case of each such interim assignment, because the related Mortgage has not been returned by the appropriate recording office, the Depositor shall deliver such documents to the Custodian as promptly as possible upon receipt thereof and, in any event, within 720 days following the Closing Date. The Depositor shall forward or cause to be forwarded to the Custodian (a) from time to time additional original documents evidencing an assumption or modification of a Mortgage Loan and (b) any other documents required to be delivered by the Depositor to the Custodian. In the event that the original Mortgage is not delivered and in connection with the payment in full of the related Mortgage Loan and the public recording office requires the presentation of a “lost instruments affidavit and indemnity” or any equivalent document, because only a copy of the Mortgage can be delivered with the instrument of satisfaction or reconveyance, the Custodian shall execute and deliver or cause to be executed and delivered such a document to the public recording office. In the case where a public recording office retains the original recorded Mortgage or in the case where a Mortgage is lost after recordation in a public recording office, the Transferor shall deliver to the Custodian a copy of such Mortgage certified by such public recording office to be a true and complete copy of the original recorded Mortgage.

If an assignment of Mortgage is to be recorded, the Depositor shall cause the Mortgage to be assigned to “U.S. Bank National Association, in trust for the MASTR Adjustable Rate Mortgages Trust 2007-1 for the benefit of the Holders of the Mortgage Pass-Through Certificates, Series 2007-1” and, subject to Section 2.02, the Master Servicer shall enforce the obligations of the related Servicer pursuant to the related Servicing Agreement to (i) cause such assignment to be in proper form for recording in the appropriate public office for real property records and (ii) cause to be delivered for recording in the appropriate public office for real property records the assignments of the Mortgages to the Trustee, except that, with respect to any assignments of Mortgage as to which the related Servicer has not received the information required to prepare such assignment in recordable form, the related Servicer’s obligation to do so and to deliver the same for such recording shall be as soon as practicable after receipt of such information and in any event within ninety (90) days after receipt thereof and except that the related Servicer need not cause to be recorded any assignment which relates to a Mortgage Loan (a) in any state where, in an Opinion of Counsel addressed to the Trustee, such recording is not required to protect the Trustee’s interests in the Mortgage Loan against the claim of any subsequent transferee or any successor to or creditor of the Depositor or the Transferor, (b) in any state where recordation is not required by either Rating Agency to obtain the initial ratings on the Certificates set forth in the Prospectus Supplement or (c) with respect to any Mortgage which has been recorded in the name of MERS, or its designee. As of the date hereof, recordation is not required in any state by either Rating Agency to obtain the initial rating on the Certificates (upon which statement the Master Servicer, the Trustee and the Custodian may conclusively rely).

In the case of Mortgage Loans that have been prepaid in full as of the Closing Date, the Depositor, in lieu of delivering the above documents to the Custodian on behalf of the Trustee, will deposit in the Collection Account the portion of such payment that is required to be deposited in the Collection Account pursuant to Section 3.07 hereof.

(c)

The Depositor does hereby establish, pursuant to the further provisions of this Agreement and the laws of the State of New York, an express trust (the “Trust”) to be known, for convenience, as “MASTR Adjustable Rate Mortgages Trust 2007-1” and U.S. Bank National Association is hereby appointed as Trustee in accordance with the provisions of this Agreement.

(d)

The Depositor and the Trustee on behalf of the Trust agree and understand that it is not intended that any Loan be included in the Trust Fund that is (i) a “High Cost Home Loan” as defined in the New Jersey Home Ownership Act effective November 27, 2003, (ii) a “High Cost Home Loan” as defined in the New Mexico Home Loan Protection Act effective January 1, 2004, (iii) a “High Cost Home Mortgage Loan” as defined in the Massachusetts Predatory Home Loan Practices Act effective November 7, 2004, (iv) a “high risk home loan” under the Illinois High Risk Home Loan Act, effective as of January 1, 2004, or (v) a “high cost home loan” under the Indiana High Cost Home Loan Law, effective January 1, 2005. The Trustee shall be entitled to indemnification from the Depositor and the Trust Fund for any loss, liability or expense arising out of, or in connection with, the provisions of the preceding sentence, including, without limitation, all costs, liabilities and expenses (including reasonable legal fees and expenses) of investigating and defending itself against any claim, action or proceeding, pending or threatened, relating to such provisions.

(e)

Each of the Collection Account and Distribution Account shall at all times be an Eligible Account, provided that the Collection Account may be deemed to be a sub-account of the Distribution Account. If at any time either the Collection Account or the Distribution Account ceases to be an Eligible Account, the Master Servicer or the Trust Administrator, as applicable, shall immediately establish and maintain a new Collection Account or Distribution Account, as applicable, that is an Eligible Account, and shall immediately transfer all funds on deposit in the former Collection Account or Distribution Account, as applicable, to the new Collection Account or Distribution Account, as applicable.

(f)

The Depositor hereby directs the Trust Administrator, solely in its capacity as Supplemental Interest Trust Trustee, to execute, deliver and perform its obligations under each of the Group I Cap 1 Agreement, the Group I Cap 2 Agreement and the Group I Swap Agreement. The Transferor, the Depositor, the Master Servicer, the Trustee and the Holders of the Group I Offered Certificates by their acceptance of such Certificates acknowledge and agree that the Supplemental Interest Trust Trustee shall execute, deliver and perform its obligations under each of the Group I Cap 1 Agreement, the Group I Cap 2 Agreement and the Group I Swap Agreement and shall do so solely in its capacity as Supplemental Interest Trust Trustee, and not in its individual capacity. Every provision of this Agreement relating to the conduct or affecting the liability of or affording protection to the Trust Administrator shall apply to the execution by the Supplemental Interest Trust Trustee of the Group I Cap 1 Agreement, the Group I Cap 2 Agreement and the Group I Swap Agreement, and the performance of its duties and satisfaction of its obligations thereunder.

Section 2.02. Acceptance by Trustee of the Mortgage Loans.

The Custodian, on behalf of the Trustee, acknowledges receipt of the documents identified in the Initial Certification issued by it in the form annexed hereto as Exhibit G and declares that it holds and will hold such related documents and the other documents delivered to it constituting the Mortgage Files, and the Custodian and Trustee together declare that it holds or will hold such other assets as are included in the Trust Fund, in trust for the exclusive use and benefit of all present and future Certificateholders and the Group I Certificate Insurer. The Custodian acknowledges that it will maintain possession of the Mortgage Notes held by it in the State of Minnesota, unless otherwise permitted by the Rating Agencies, the Trustee and the Group I Certificate Insurer.

The Custodian agrees to execute and deliver on the Closing Date to the Depositor and the Trustee an Initial Certification in the form annexed hereto as Exhibit G. Based on its review and examination, and only as to the documents identified in such Initial Certification, the Custodian acknowledges, subject to any applicable exceptions noted on Exhibit G, that such documents appear regular on their face and relate to such Mortgage Loan. The Custodian shall be under no duty or obligation to (i) inspect, review or examine said documents, instruments, certificates or other papers to determine that the same are genuine, enforceable or appropriate for the represented purpose or that they have actually been recorded in the real estate records or that they are other than what they purport to be on their face or (ii) determine whether the Mortgage File should include any of the documents specified in Section 2.01(b)(i)(D) with respect to each Mortgage Loan that is not a Cooperative Mortgage Loan and Section 2.01(b)(ii)(H) with respect to each Cooperative Mortgage Loan, unless the Mortgage Loan Schedule indicates that such documents are applicable.

Not later than 90 days after the Closing Date, the Custodian shall deliver to the Depositor, the Group I Certificate Insurer, the Trustee and the Transferor a Final Certification in the form annexed hereto as Exhibit H, with any applicable exceptions noted thereon. The Custodian shall make available, upon request of any Certificateholder or the Group I Certificate Insurer, a copy of any exceptions noted on the Initial Certification or the Final Certification. The Custodian shall make available, upon request of the Trustee, the identity of the originator for any Mortgage Loan with a material exception.

If, in the course of such review, the Custodian finds any document constituting a part of a related Mortgage File which does not meet the requirements of Section 2.01, the Custodian shall list such as an exception in the Final Certification; provided, however, that the Custodian shall not make any determination as to whether (i) any endorsement is sufficient to transfer all right, title and interest of the party so endorsing, as noteholder or assignee thereof, in and to that Mortgage Note, (ii) any assignment is in recordable form or is sufficient to effect the assignment of and transfer to the assignee thereof under the mortgage to which the assignment relates or (iii) the Mortgage File should include any of the documents specified in Section 2.01(b)(i)(D) with respect to each Mortgage Loan that is not a Cooperative Mortgage Loan and Section 2.01(b)(ii)(H) with respect to each Cooperative Mortgage Loan, unless the Mortgage Loan Schedule indicates that such documents are applicable.

Upon receiving each Final Certification from the Custodian, the Trustee shall notify the Transferor and the Group I Certificate Insurer of any document defects listed as exceptions in each such Final Certification. The Transferor shall promptly correct or cure such document defects, and if the Transferor fails to correct or cure the defect within ninety (90) days of the earlier of its discovery or its receipt of written notice of any document constituting a part of a Mortgage File that does not meet the requirements of Section 2.01, and such defect materially and adversely affects the interests of the Certificateholders or the Group I Certificate Insurer in the related Mortgage Loan, the Transferor shall repurchase the affected Mortgage Loan from the Trustee at the Purchase Price. In each case, such Deleted Mortgage Loan will be removed from the Trust. Any such purchase of a Deleted Mortgage Loan shall not be effected prior to the delivery to the Custodian of a Request for Release substantially in the form of Exhibit M. The Purchase Price for any such Deleted Mortgage Loan shall be paid by the Transferor to the Master Servicer for deposit in the Collection Account on or prior to the Distribution Account Deposit Date for the Distribution Date in the month following the month of repurchase and, upon receipt of such deposit, the Master Servicer shall instruct the Custodian to release, and the Custodian shall release, the related Mortgage File to the Transferor and the Trustee shall execute and deliver at the Transferor’s written request such instruments of transfer or assignment prepared by the Transferor, in each case without recourse, representation or warranty, as shall be necessary to vest in the Transferor, or a designee, the Trustee’s interest in any Deleted Mortgage Loan released pursuant hereto. The Transferor shall promptly reimburse the Master Servicer and the Trustee for any expenses reasonably incurred by the Master Servicer or the Trustee in respect of enforcing such repurchase by the Transferor.

The Custodian shall retain possession and custody of each related Mortgage File in accordance with and subject to the terms and conditions set forth herein. Pursuant to the terms of the related Servicing Agreement, the Master Servicer shall cause each of the related Servicers to promptly deliver to the Custodian who shall thereupon promptly deposit within each Mortgage File, upon the execution or receipt thereof, the originals of such other documents or instruments constituting the Mortgage File as come into the possession of the related Servicers from time to time.

It is understood and agreed that the obligations of the Transferor hereunder to purchase any Mortgage Loan which does not meet the requirements of Section 2.01 above or substitute for the related Mortgage Loan an Eligible Substitute Mortgage Loan shall constitute the sole remedies respecting such defect available to the Trustee, the Master Servicer, the Depositor and any Certificateholder.

Section 2.03. Remedies for Breaches of Representations and Warranties.

The Transferor hereby makes the representations and warranties set forth in Schedule II hereto, and by this reference incorporated herein, to the Depositor, the Group I Certificate Insurer and the Trustee, as of the Closing Date, or if so specified therein, as of the Cut-off Date. With respect to any representation and warranties set forth on Schedule II hereto which are made to the best of the Transferor’s knowledge if it is discovered by any of the Depositor, the Group I Certificate Insurer, the Master Servicer, the Transferor, any Servicer, the Trustee or the Trust Administrator that the substance of such representation and warranty is inaccurate and such inaccuracy materially and adversely affects the value of the related Mortgage Loan or the interests of the Certificateholders or the Group I Certificate Insurer therein, notwithstanding the Transferor’s lack of knowledge with respect to the substance of such representation or warranty, such inaccuracy shall be deemed a breach of the applicable representation or warranty.

Upon discovery by any of the Depositor, the Group I Certificate Insurer, the Transferor, the Master Servicer, the Trust Administrator or the Custodian of a breach of a representation or warranty made by the Transferor pursuant to this Section 2.03 that materially and adversely affects the interests of the Certificateholders or the Group I Certificate Insurer in any Mortgage Loan, the party discovering such breach shall give prompt notice thereof to the other parties and the Trustee. Notwithstanding the foregoing, (i) a breach which causes a Mortgage Loan not to constitute a “qualified mortgage” within the meaning of Section 860G(a)(3) of the Code, or (ii) a breach of any of the representations and warranties set forth in clauses (xiii), (xv), (xxxvi), (xxxvii), (xxxix), (xl), (xli), (xliii) through (li) of Schedule II, in each case, will be deemed automatically to materially and adversely affect the interests of the Certificateholders in such Mortgage Loan. Upon receiving notice of a breach, the Trustee shall in turn notify the Transferor of such breach. The Trustee shall enforce the obligations of the Transferor in accordance with this Section 2.03 to correct or cure any such breach of a representation or warranty made herein, and if the Transferor fails to correct or cure the defect within such period, and such defect materially and adversely affects the interests of the Certificateholders and the Group I Certificate Insurer in the related Mortgage Loan, the Trustee shall enforce the Transferor’s obligations hereunder to (i) purchase such Mortgage Loan at the Purchase Price or (ii) substitute for the related Mortgage Loan an Eligible Substitute Mortgage Loan. In each case, such Deleted Mortgage Loan will be removed from the Trust Fund.

The Transferor hereby covenants that within ninety (90) days of the earlier of its discovery or its receipt of written notice from any party of a breach of any representation or warranty made pursuant to this Section 2.03 which materially and adversely affects the interest of the Certificateholders or the Group I Certificate Insurer in any Mortgage Loan, it shall cure such breach in all material respects, and if such breach is not so cured, shall, (i) if such ninety (90) day period expires prior to the second anniversary of the Closing Date, remove such Deleted Mortgage Loan from the Trust Fund and substitute in its place an Eligible Substitute Mortgage Loan or Mortgage Loans into the Trust Fund, in the manner and subject to the conditions set forth in this Section; or (ii) repurchase the affected Mortgage Loan or Mortgage Loans from the Trustee at the Purchase Price in the manner set forth below. The Transferor shall promptly reimburse the Master Servicer, the NIMS Insurer, the Group I Certificate Insurer and the Trustee for any expenses reasonably incurred by the Master Servicer, the NIMS Insurer, the Group I Certificate Insurer or the Trustee in respect of enforcing the remedies for such breach by the Transferor.

With respect to any Eligible Substitute Mortgage Loan or Mortgage Loans, the Transferor shall deliver to the Custodian on behalf of the Trustee, for the benefit of the Certificateholders and the Group I Certificate Insurer, the Mortgage Note, the Mortgage, the related assignment of the Mortgage, and such other documents and agreements as are required by Section 2.01, with the Mortgage Note endorsed and the Mortgage assigned as required by Section 2.01. No substitution is permitted to be made on any day in any calendar month after the Determination Date for such month.

With respect to substitutions made by the Transferor, Scheduled Payments due with respect to Eligible Substitute Mortgage Loans in the month of substitution shall not be part of the Trust Fund and will be retained by the Transferor on the next succeeding Distribution Date. For the month of substitution, distributions to Certificateholders will include the monthly payment due on any Deleted Mortgage Loan for such month and thereafter the Transferor shall be entitled to retain all amounts received in respect of such Deleted Mortgage Loan. The Custodian shall amend the Mortgage Loan Schedule for the benefit of the Certificateholders and the Group I Certificate Insurer to reflect the removal of such Deleted Mortgage Loan and the substitution of the Eligible Substitute Mortgage Loan or Loans and the Custodian shall deliver the amended Mortgage Loan Schedule to the Trustee. Upon such substitution, the Eligible Substitute Mortgage Loan or Loans shall be subject to the terms of this Agreement in all respects, and the Transferor shall be deemed to have made with respect to such Eligible Substitute Mortgage Loan or Loans, as of the date of substitution, the representations and warranties made pursuant to this Section 2.03 with respect to such Mortgage Loan. Upon any such substitution and the deposit to the Collection Account of the amount required to be deposited therein in connection with such substitution as described in the following paragraph, the Custodian shall release the Mortgage File held for the benefit of the Certificateholders relating to such Deleted Mortgage Loan to the Transferor and the Trustee shall execute and deliver at the Transferor’s direction such instruments of transfer or assignment prepared by the Transferor, without recourse, representation or warranty, as shall be necessary to vest title in the Transferor, as applicable, or its designee, the Trustee’s interest in any Deleted Mortgage Loan substituted for pursuant to this Section 2.03.

For any month in which the Transferor substitutes one or more Eligible Substitute Mortgage Loans for one or more Deleted Mortgage Loans, the Master Servicer will determine the amount (if any) by which the aggregate principal balance of all such Eligible Substitute Mortgage Loans as of the date of substitution is less than the aggregate Principal Balance of all such Deleted Mortgage Loans (after application of the scheduled principal portion of the monthly payments received in the month of substitution). The amount of such shortage (the “Substitution Adjustment Amount”) plus an amount equal to the aggregate of any unreimbursed Advances with respect to such Deleted Mortgage Loans shall be remitted by the Transferor to the Master Servicer, and the Master Servicer shall deposit such amounts received from the Transferor into the Collection Account on or before the Distribution Account Deposit Date for the Distribution Date in the month succeeding the calendar month during which the related Mortgage Loan became required to be purchased or replaced hereunder.

In the event that the Transferor shall have repurchased a Mortgage Loan, the Purchase Price therefor shall be deposited in the Collection Account pursuant to Section 3.07 on or before the Distribution Account Deposit Date for the Distribution Date in the month following the month during which the Transferor became obligated hereunder to repurchase or replace such Mortgage Loan and upon such deposit of the Purchase Price and receipt of a Request for Release in the form of Exhibit M hereto, the Custodian shall release the related Mortgage File held for the benefit of the Certificateholders and the Group I Certificate Insurer to the Transferor, and the Trustee shall execute and deliver at the Transferor’s direction such instruments of transfer or assignment prepared by the Transferor, in each case without recourse, representation or warranty, as shall be necessary to transfer title from the Trustee. It is understood and agreed that the obligation under this Agreement of the Transferor to cure, repurchase or replace any Mortgage Loan as to which a breach has occurred and is continuing shall constitute the sole remedies against the Transferor respecting such matters available to Certificateholders, the Master Servicer, the NIMS Insurer, the Depositor, the Trust Administrator or the Trustee on their behalf.

The provisions of this Section 2.03 shall survive the conveyance and assignment of the Mortgage Files to the Trustee and the delivery of the respective Mortgage Files to the Custodian for the benefit of the Trustee, the Certificateholders and the Group I Certificate Insurer.

Section 2.04. Representations and Warranties of the Depositor as to the Mortgage Loans.

The Depositor hereby represents and warrants to the Trustee, the Trust Administrator, the NIMS Insurer, the Group I Certificate Insurer and the Master Servicer with respect to each Mortgage Loan as of the date hereof or such other date set forth herein that as of the Closing Date, and following the transfer of the Mortgage Loans to it by the Transferor, the Depositor had good title to the Mortgage Loans and the Mortgage Notes were subject to no offsets, liens, defenses or counterclaims.

It is understood and agreed that the representations and warranties set forth in this Section 2.04 shall survive delivery of the Mortgage Files to the Custodian. Upon discovery by the Depositor, the Transferor, the Master Servicer, the Group I Certificate Insurer, the Trust Administrator, the NIMS Insurer or the Trustee of a breach of any of the foregoing representations and warranties set forth in this Section 2.04 (referred to herein as a “breach”), which breach materially and adversely affects the interest of the Certificateholders or the Group I Certificate Insurer, the party discovering such breach shall give prompt written notice to the other parties hereto and to each Rating Agency.

Section 2.05. Representation and Warranty of the Depositor as to the Trust.

The Depositor hereby represents and warrants, for the benefit of the Group I Swap Provider, that the Trust is a common law trust duly organized and validly existing under the laws of the state of New York.

Section 2.06. Execution and Delivery of Certificates.

The Trustee acknowledges the transfer and assignment to it of the Trust Fund by the Depositor pursuant to Section 2.01 hereof and acknowledges the issuance of the REMIC Interests as described in the Preliminary Statement in exchange therefor. The Trustee further acknowledges the transfer and assignment to it by the Underwriter pursuant to Section 6.07 hereof of the Uncertificated REMIC Interests described in the Preliminary Statement. Concurrently with such transfers and assignments, the Trust Administrator, on behalf of the Trustee, has executed, authenticated and delivered to or upon the order of the Depositor, the Certificates in authorized denominations evidencing directly or indirectly the entire ownership of the Trust Fund. The Trustee agrees to hold the Trust Fund and the Uncertificated REMIC Interests described in the Preliminary Statement and to exercise the rights referred to above for the benefit of all present and future Holders of the Certificates and the Group I Certificate Insurer and to perform the duties set forth in this Agreement to the best of its ability, to the end that the interests of the Holders of the Certificates and the Group I Certificate Insurer may be adequately and effectively protected.

Section 2.07. REMIC Matters.

The Preliminary Statement sets forth the designations as “regular interests” or “residual interests” and “latest possible maturity date” for federal income tax purposes of all interests created hereby. The “Startup Day” for purposes of the REMIC Provisions shall be the Closing Date. Each REMIC shall have the calendar year as its fiscal year and shall use the accrual method of accounting.

Section 2.08. Covenants of the Master Servicer.

The Master Servicer hereby covenants to the Depositor and the Trustee as follows:

(i)

subject to Section 3.01, the Master Servicer shall cause each Servicer to perform its obligations under the applicable Servicing Agreement; and

ARTICLE III

ADMINISTRATION AND MASTER
SERVICING OF MORTGAGE LOANS

Section 3.01. Master Servicing of Mortgage Loans.

For and on behalf of the Certificateholders and the Group I Certificate Insurer, the Master Servicer shall supervise, monitor and oversee the obligation of the Servicers to service and administer their respective Mortgage Loans in accordance with the terms of the applicable Servicing Agreement and shall have full power and authority to do any and all things which it may deem necessary or desirable in connection with such master servicing and administration. In performing its obligations hereunder, the Master Servicer shall act in a manner consistent with this Agreement, subject to the prior sentence, and with customary and usual standards of practice of prudent mortgage loan master servicers. Furthermore, the Master Servicer shall oversee and consult with each Servicer as necessary from time to time to carry out the Master Servicer’s obligations hereunder, shall receive, review and evaluate all reports, information and other data provided to the Master Servicer by each Servicer and shall cause each Servicer to perform and observe the covenants, obligations and conditions to be performed or observed by such Servicer under the applicable Servicing Agreement. The Master Servicer shall independently and separately monitor each Servicer’s servicing activities with respect to each related Mortgage Loan, reconcile the results of such monitoring with such information provided in the previous sentence on a monthly basis and coordinate corrective adjustments to the Servicers’ and Master Servicer’s records, and based on such reconciled and corrected information, prepare the statements specified in Section 4.04 and any other information and statements required hereunder.

In the review of each Servicer’s activities, the Master Servicer may rely upon an officer’s certificate of the Servicer with regard to such Servicer’s compliance with the terms of its Servicing Agreement. In the event that the Master Servicer, in its judgment, determines that a Servicer should be terminated in accordance with its Servicing Agreement, or that a notice should be sent pursuant to such Servicing Agreement with respect to the occurrence of an event that, unless cured, would constitute grounds for such termination, the Master Servicer shall notify the Depositor, the Trust Administrator, the Group I Certificate Insurer and the Trustee thereof and the Master Servicer shall issue such notice or take such other action as it deems appropriate.

(b)

The Master Servicer, for the benefit of the Trustee, the Trust Administrator, the Certificateholders and the Group I Certificate Insurer, shall enforce the obligations of each Servicer under the related Servicing Agreement, and shall, in the event that a Servicer fails to perform its obligations in accordance with the related Servicing Agreement, subject to the preceding paragraph, terminate the rights and obligations of such Servicer thereunder and act as successor Servicer of the related Mortgage Loans or cause the Trustee to enter into a new Servicing Agreement with a successor Servicer selected by the Master Servicer; provided, however, it is understood and acknowledged by the parties hereto that there will be a period of transition (not to exceed 90 days) before the actual servicing functions can be fully transferred to such successor Servicer. Such enforcement, including, without limitation, the legal prosecution of claims, termination of Servicing Agreements and the pursuit of other appropriate remedies, shall be in such form and carried out to such an extent and at such time as the Master Servicer, in its good faith business judgment, would require were it the owner of the related Mortgage Loans. The Master Servicer shall pay the costs of such enforcement at its own expense, provided that the Master Servicer shall not be required to prosecute or defend any legal action except to the extent that the Master Servicer shall have received reasonable indemnity for its costs and expenses in pursuing such action.

(c)

To the extent that the costs and expenses of the Master Servicer related to any termination of a Servicer, appointment of a successor Servicer or the transfer and assumption of servicing by the Master Servicer with respect to any Servicing Agreement (including, without limitation, (i) all legal costs and expenses and all due diligence costs and expenses associated with an evaluation of the potential termination of the Servicer as a result of an event of default by such Servicer and (ii) all costs and expenses associated with the complete transfer of servicing, including all servicing files and all servicing data and the completion, correction or manipulation of such servicing data as may be required by the successor servicer to correct any errors or insufficiencies in the servicing data or otherwise to enable the successor servicer to service the Mortgage Loans in accordance with the related Servicing Agreement) are not fully and timely reimbursed by the terminated Servicer, the Master Servicer shall be entitled to reimbursement of such costs and expenses from the Collection Account.

(e)

If the Master Servicer acts as Servicer, it will not assume liability for the representations and warranties of the Servicer, if any, that it replaces.

(f)

If a Servicer fails to make its required payment of Compensating Interest on any Distribution Date, the Master Servicer will be required to make such payment of Compensating Interest to the same extent that such Servicer was required to make such payment of Compensating Interest.

(g)

To the extent a Servicer requests the consent of the Trust or the Master Servicer with respect to any servicing-related matter for which the applicable Servicer is required to seek consent under the applicable Servicing Agreement or Assignment Agreement, the Master Servicer shall promptly or within the time frame specified in such Servicing Agreement, if any, evaluate such request for consent in the best interest of the Trust and the Certificateholders, and grant or withhold such consent accordingly.

(h)

To the extent a Servicer is obligated under the related Servicing Agreement to procure the consent of the Master Servicer in connection with the Servicer’s engagement of a Subservicer to perform any servicing responsibilities under the related Servicing Agreement with respect to the related Mortgage Loans, the Master Servicer will only give such consent if that Subservicer first agrees in writing with such Servicer and the Master Servicer to deliver an Annual Statement of Compliance, an Assessment of Compliance and an Accountant’s Attestation in such manner and at such times that permit that Servicer and the Master Servicer to comply with Sections 3.21 and 3.22 of this Agreement.

(i)

The Master Servicer shall enforce any negative covenant in the related Servicing Agreement which prohibits a Servicer from outsourcing one or more separate servicing functions under the related Servicing Agreement with respect to the Mortgage Loans to any Subcontractor unless that Subcontractor first agrees in writing with such Servicer and the Master Servicer to deliver an Assessment of Compliance and an Accountant’s Attestation in such manner and at such times that permits that Servicer and the Master Servicer to comply with Section 3.22 of this Agreement.

Notwithstanding any other provision of this Agreement, no Mortgaged Property acquired by the Trust Fund shall be rented (or allowed to continue to be rented) or otherwise used for the production of income by or on behalf of the Trust Fund in such a manner or pursuant to any terms that would (i) cause such Mortgaged Property to fail to qualify as “foreclosure property” within the meaning of Section 860G(a)(8) of the Code or (ii) subject any REMIC hereunder to the imposition of any federal, state or local income taxes on the income earned from such Mortgaged Property under Section 860G(c) of the Code or otherwise, unless the Master Servicer or related Servicer, as applicable, has agreed to indemnify and hold harmless the Trust Fund with respect to the imposition of any such taxes.

Section 4.11. Determination of MTA

On the first MTA Determination Date, MTA for any Class of Group I MTA Certificates shall be equal to the Initial MTA Rate, and on each MTA Determination Date thereafter for any Class of Group I MTA Certificates, the Trust Administrator shall determine MTA for the applicable Distribution Date on the basis of the twelve-month average yields on United States Treasury securities adjusted to a constant maturity of one year, as published by the Federal Reserve Board in Statistical Release H.15(519).

If on any MTA Determination Date for a Class of Group I MTA Certificates, the Trust Administrator is unable to determine MTA on the basis of the method set forth in the preceding paragraph, MTA for the applicable Distribution Date will be whichever is higher of (x) MTA as determined on the previous MTA Determination Date for such Class of Group I MTA Certificates or (y) the Reserve Interest Rate.

If on any MTA Determination Date for a Class of Group I MTA Certificates, the Trust Administrator is unable to determine MTA on the basis of the method set forth in the preceding paragraph, the Trust Administrator will choose a new index for the Group I MTA Certificates that is based on comparable information. When the Trust Administrator chooses a new index for the Group I MTA Certificates, it will increase or decrease the related margin by the difference between MTA for the final three years it was in effect and the average of the most recent three years for the replacement index. The related margin will be increased by that difference if the average MTA is greater than the average replacement index and the related margin will be decreased by that difference if the replacement index is greater than the average MTA. The Trust Administrator will have no liability for the selection of such alternative index (and will be entitled to rely on such advice, if any, as it may deem appropriate in such selection), except that the Trust Administrator will select a particular index as the alternative index only if it receives an opinion of counsel (furnished at the trust fund’s expense) that the selection of such index will not cause any REMIC to lose its classification as a REMIC for federal income tax purposes.

The establishment of MTA by the Trust Administrator and the Trust Administrator’s subsequent calculation of the rates of interest applicable to each of the Group I MTA Certificates will, in the absence of manifest error, be final and binding. After a MTA Determination Date, the Trust Administrator shall provide the Pass-Through Rates of the Group I MTA Certificates for the related Distribution Date to Certificate Owners or Holders of Group I MTA Certificates who place a telephone call to the Trust Administrator at (000) 000-0000 and make a request therefor.

Section 4.12. Group I—Determination of LIBOR.

On the first LIBOR Determination Date, LIBOR for any Class of Group I LIBOR Certificates shall be equal to the Initial LIBOR Rate, and on each LIBOR Determination Date thereafter for any Class of Group I LIBOR Certificates, the Trust Administrator shall determine LIBOR for the applicable Distribution Date on the basis of the British Bankers’ Association (“BBA”) “Interest Settlement Rate” for one month deposits in U.S. Dollars as found on Telerate page 3750 as of 11:00 a.m. London time on such LIBOR Determination Date. As used herein, “Telerate page 3750” means the display designated as page 3750 on the Bridge Telerate Service.

If on any LIBOR Determination Date for any Class of Group I LIBOR Certificates, the Trust Administrator is unable to determine LIBOR on the basis of the method set forth in the preceding paragraph, LIBOR for the applicable Distribution Date will be whichever is higher of (x) LIBOR as determined on the previous LIBOR Determination Date for such Class of Certificates or (y) the Reserve Interest Rate. The “Reserve Interest Rate” will be the rate per annum which the Trust Administrator determines to be either (A) the arithmetic mean (rounding such arithmetic mean upwards if necessary to the nearest whole multiple of 1/16%) of the one month U.S. Dollar lending rates that New York City banks selected by the Trust Administrator are quoting, on the relevant LIBOR Determination Date, to the principal London offices of at least two leading banks in the London interbank market or (B) in the event that the Trust Administrator can determine no such arithmetic mean, the lowest one month U.S. Dollar lending rate that the New York City banks selected by the Trust Administrator are quoting on such LIBOR Determination Date to leading European banks.

If on any LIBOR Determination Date for any Class of Group I LIBOR Certificates, the Trust Administrator is required but is unable to determine the Reserve Interest Rate in the manner provided in the preceding paragraph, LIBOR for the applicable Distribution Date will be LIBOR as determined on the previous LIBOR Determination Date for such Class of Certificates, or, in the case of the first LIBOR Determination Date, the Initial LIBOR Rate.

The establishment of LIBOR by the Trust Administrator and the Trust Administrator’s subsequent calculation of the rates of interest applicable to each of the Group I LIBOR Certificates will, in the absence of manifest error, be final and binding. After a LIBOR Determination Date, the Trust Administrator shall provide the Pass-Through Rates of the Group I LIBOR Certificates for the related Distribution Date to Certificate Owners or Holders of such Certificates who place a telephone call to the Trust Administrator at (000) 000-0000 and make a request therefor.

(D)

from the remaining Group II Available Funds, to the Class II-B-4 Certificates in the following order: (1) the Group II Accrued Certificate Interest on the Class II-B-4 Certificates for that Distribution Date and (2) the Class II-B-4 Certificates’ Group II Allocable Share for that Distribution Date until the Class Principal Balance is reduced to zero;

(E)

(F)

from the remaining Group II Available Funds, to the Class II-B-6 Certificates in the following order: (1) the Group II Accrued Certificate Interest on the Class II-B-6 Certificates for that Distribution Date and (2) the Class II-B-6 Certificates’ Group II Allocable Share for that Distribution Date until the Class Principal Balance is reduced to zero;

(G)

to the Class II-A-LR Certificates any remaining portion (which is expected to be zero) of the Group II Available Funds in REMIC IB for that Distribution Date; and

(H)

to the Class II-A-UR Certificates any remaining portion (which is expected to be zero) of the Group II Available Funds in Master REMIC II for that Distribution Date and to the Class R-X Certificates any remaining portion (which is expected to be zero) of the Group II Available Funds in the Class I-P REMIC for that Distribution Date.

Pro rata distributions of interest among Classes of Group II Certificates are required to be made in proportion to the then current amount of interest to which the applicable Classes are entitled. Pro rata distributions of principal among Classes of Group II Certificates are required to be made in proportion to the then-current Certificate Principal Balance of the applicable Classes.

(b)

On each Distribution Date, all Class II-P Prepayment Charges remitted to the Trust during the related Prepayment Period shall be distributed by the Trust Administrator to the Holders of the Class II-P Certificates.

(c)

On each Distribution Date, the amount referred to in clause (i) of the definition of Group II Accrued Certificate Interest for each Class of Group II Senior Certificates and Group II Subordinate Certificates for such Distribution Date shall be reduced by (i) the related Class’ Pro Rata Share of Net Prepayment Interest Shortfalls with respect to the Group II Mortgage Loans, based on such Class’ Group II Accrued Certificate Interest for such Distribution Date without taking into account such Net Prepayment Interest Shortfalls and (ii) the related Class’ Pro Rata Share of (A) after the related Special Hazard Coverage Termination Date, with respect to each Group II Mortgage Loan that became a Special Hazard Mortgage Loan during the calendar month preceding the month of such Distribution Date, the excess of one month’s interest at the related Net Mortgage Rate on the Scheduled Principal Balance of such Group II Mortgage Loan as of the Due Date in such month over the amount of Liquidation Proceeds applied as interest on such Group II Mortgage Loan with respect to such month, (B) after the Bankruptcy Coverage Termination Date, with respect to each Group II Mortgage Loan that became subject to a Bankruptcy Loss during the calendar month preceding the month of such Distribution Date, the interest portion of the related Deficient Valuation, (C) each Relief Act Reduction incurred on a Group II Mortgage Loan during the calendar month preceding the month of such Distribution Date and (D) after the Fraud Loss Coverage Termination Date with respect to each Group II Mortgage Loan that became a Fraud Loan during the calendar month preceding the month of such Distribution Date, the excess of one month’s interest at the related Net Mortgage Rate on the Scheduled Principal Balance of such Group II Mortgage Loan as of the Due Date in such month over the amount of Liquidation Proceeds applied as interest on such Group II Mortgage Loan with respect to such month.

(d)

Notwithstanding the priority and allocation contained in Section 5.02(a)(ii)(A) through (F), if with respect to any Class of Group II Subordinate Certificates on any Distribution Date, (I) such Class has not satisfied the related Group II Class Prepayment Distribution Trigger, no distribution of amounts pursuant to clauses (ii) and (iii) of the definition of Group II Subordinate Optimal Principal Amount will be made to any such Classes (the “Restricted Classes”) and the amount of such amounts pursuant to clauses (ii) and (iii) of the definition of Group II Subordinate Optimal Principal Amount otherwise distributable to the Restricted Classes shall be distributed to any Classes of Group II Subordinate Certificates, that are not Restricted Classes, having lower numerical Class designations than such Class, pro rata, based on their respective Class Principal Balances immediately prior to such Distribution Date and shall be distributed in the sequential order provided in Section 5.02(a)(ii)(A) through (F); provided, however, that, if all of the Group II Subordinate Certificates are Restricted Classes, then such amounts shall be distributed to the most senior Class of such Group II Subordinate Certificates outstanding and (II) such Class has not satisfied the Group II Subordinate Certificates Fractional Interest Test, the Classes of Group II Subordinate Certificates that have higher numerical designations shall receive, in respect of clauses (ii) and (iii) of the definition of Group II Subordinate Optimal Principal Amount, an amount equal to the product of (i) their pro rata shares (based on the Certificate Principal Balances of all Group II Subordinate Certificates that are entitled to receive principal distributions on such date) and (ii) the percentages set forth in the following table:

Distribution Date occurring in	Percentage
January 2007 through December 2013	0%
January 2014 through December 2014	30%
January 2015 through December 2015	40%
January 2016 through December 2016	60%
January 2017 through December 2017	80%
January 2018 and thereafter	100%

Each Class of Group II Subordinate Certificates that received a full pro rata share as described above shall be allocated any remaining amount in respect of clauses (ii) and (iii) of the definition of Group II Subordinate Optimal Principal Amount, pro rata (based on the Certificate Principal Balances of only those Group II Subordinate Certificates that received a full pro rata share). The calculation of any amount to be distributed under this Section 5.02(d) shall be made by the Master Servicer.

(e)

Reserved.

(f)

On each Distribution Date, prior to distributions on the Certificates as provided in Section 5.02(a)-(e), Group II Available Funds shall be deemed distributed to the REMIC IB Interests as set forth in the Preliminary Statement.

(g)

Any Fair Market Value Excess collected in connection with a termination of the portion of the Trust Fund related to Loan Group II pursuant to Section 11.03 shall be distributed to the Holders of the Class II-A-LR Certificates.

Section 5.03. Group II—Allocation of Realized Losses.

(a)

On or prior to each Distribution Date, the Master Servicer shall determine the total amount of Realized Losses with respect to Group II Mortgage Loans, including Excess Losses and the allocation of such total amount as set forth below. Realized Losses occurring on the Group II Mortgage Loans shall be allocated as follows:

(i)

any Realized Loss (other than an Excess Loss) on a Group II Mortgage Loan shall be allocated first, to the Group II Subordinate Certificates in reverse order of their respective numerical Class designations (beginning with the Class of Group II Subordinate Certificates then outstanding with the highest numerical Class designation) until the respective Class Principal Balance of each such Class is reduced to zero and second, to the Classes of Group II Senior Certificates, pro rata on the basis of their respective Class Principal Balances immediately prior to the related Distribution Date until the Class Principal Balance of each such Class has been reduced to zero; provided, however, that on or after the Cross-Over Date, the losses allocable to the Class II-A-1 Certificates under this paragraph will instead be allocated to the Class II-A-2 Certificates (in addition to other losses borne by such Certificates) until the Class Principal Balance of the Class II-A-2 Certificates has been reduced to zero.

(ii)

any Excess Losses occurring on the Group II Mortgage Loans shall be allocated among the Group II Senior Certificates and each Class of Group II Subordinate Certificates, pro rata, based upon their respective Class Principal Balances (or, in the case of such Group II Subordinate Certificates in the aggregate, the Group II Subordinate Amount, the aggregate amount so allocated to the Group II Subordinate Certificates then to be allocated among such Group II Subordinate Certificates, pro rata, based on their respective Class Principal Balances) after giving effect to distributions of principal on such Distribution Date.

(b)

The Class Principal Balance of the Class of Group II Subordinate Certificates then outstanding with the highest numerical Class designation shall be reduced on each Distribution Date by the amount, if any, by which the aggregate of the Class Principal Balances of all outstanding Classes of Group II Certificates (after giving effect to the distribution of principal and the allocation of Realized Losses with respect to Group II Mortgage Loans on such Distribution Date) exceeds the Group II Pool Principal Balance for the following Distribution Date.

(c)

Any allocation of Realized Losses with respect to Group II Mortgage Loans to a Group II Certificate or any reduction in the Certificate Principal Balance of a Group II Certificate, pursuant to Section 5.03(a) above shall be accomplished by reducing the Certificate Principal Balance thereof, as applicable, immediately following the distributions made on the related Distribution Date in accordance with the definition of “Certificate Principal Balance” herein; provided that no Realized Loss with respect to a Group II Mortgage Loan shall be allocated to reduce the Certificate Principal Balance of a Group II Certificate to the extent that such allocation would reduce the aggregate Certificate Principal Balance of all of the Group II Certificates to an amount less than the Group II Pool Principal Balance for the following Distribution Date, less any related Deficiency Valuations occurring before the related Bankruptcy Loss Coverage Termination Date (such limitation, a “Loss Allocation Limitation”).

(d)

Prior to the Cross-Over Date, with respect to Recoveries received during a Prepayment Period with respect to any Group II Mortgage Loans, the Class Principal Balance of one or more Classes of Group II Certificates that have previously had Realized Losses allocated, will be increased, as follows:

(i)

first, up to the amount of the Recoveries with respect to the Group II Mortgage Loans, the Class Principal Balance of each Class of Group II Senior Certificates will be increased, pro rata, up to the amount of unrecovered Realized Losses previously allocated to each such Class, if any; and

(ii)

second, up to the amount of the Recoveries remaining after allocation pursuant to the preceding clause (i), the Class Principal Balance of each Class of Group II Subordinate Certificates, in order of seniority, will be increased, by the amount of unrecovered Realized Losses previously allocated to each such Class, if any.

(e)

Commencing on the Cross-Over Date, the Trust Administrator shall distribute the amount of any Recovery with respect to a Group II Mortgage Loan received during a Prepayment Period, pro rata, based on Class Principal Balances, to the Classes of Group II Senior Certificates; provided, however, that any distribution to a Class of Group II Certificates pursuant to this Section 5.03(e) shall not reduce the Class Principal Balance of such Class.

ARTICLE VI

THE CERTIFICATES

Section 6.01. The Certificates.

The Certificates shall be substantially in the forms attached hereto as Exhibits A through F. The Certificates shall be issuable in registered form, in the minimum denominations, integral multiples in excess thereof (except that one Certificate in each Class may be issued in a different amount which must be in excess of the applicable minimum denomination) and aggregate denominations per Class set forth in the Preliminary Statement.

Subject to Section 11.02 hereof respecting the final distribution on the Certificates, on each Distribution Date the Trust Administrator shall make distributions to each Certificateholder of record on the preceding Record Date either (x) by wire transfer in immediately available funds to the account of such holder at a bank or other entity having appropriate facilities therefor, if such Holder has so notified the Trust Administrator in writing at least five Business Days prior to the related Record Date or (y) by check mailed by first class mail to such Certificateholder at the address of such holder appearing in the Certificate Register.

The Certificates shall be executed by manual or facsimile signature on behalf of the Trust Administrator by an authorized officer. Certificates bearing the manual or facsimile signatures of individuals who were, at the time when such signatures were affixed, authorized to sign on behalf of the Trust Administrator shall bind the Trust Administrator, notwithstanding that such individuals or any of them have ceased to be so authorized prior to the countersignature and delivery of such Certificates or did not hold such offices at the date of such Certificate. No Certificate shall be entitled to any benefit under this Agreement, or be valid for any purpose, unless countersigned by the Trust Administrator by manual signature, and such countersignature upon any Certificate shall be conclusive evidence, and the only evidence, that such Certificate has been duly executed and delivered hereunder. All Certificates shall be dated the date of their countersignature. On the Closing Date, the Trust Administrator shall countersign the Certificates to be issued at the direction of the Depositor, or any affiliate thereof.

The Depositor shall provide, or cause to be provided, to the Trust Administrator on a continuous basis, an adequate inventory of Certificates to facilitate transfers.

Section 6.02. Certificate Register; Registration of Transfer and Exchange of Certificates.

(a)

The Trust Administrator shall maintain, or cause to be maintained in accordance with the provisions of Section 6.06 hereof, a Certificate Register for the Trust Fund in which, subject to the provisions of subsections (b) and (c) below and to such reasonable regulations as it may prescribe, the Trust Administrator shall provide for the registration of Certificates and of transfers and exchanges of Certificates as herein provided. Upon surrender for registration of transfer of any Certificate, the Trust Administrator shall execute and deliver, in the name of the designated transferee or transferees, one or more new Certificates of the same Class and aggregate Percentage Interest.

At the option of a Certificateholder, Certificates may be exchanged for other Certificates of the same Class in authorized denominations and evidencing the same aggregate Percentage Interest upon surrender of the Certificates to be exchanged at the office or agency of the Trust Administrator. Whenever any Certificates are so surrendered for exchange, the Trust Administrator shall execute, authenticate, and deliver the Certificates which the Certificateholder making the exchange is entitled to receive. Every Certificate presented or surrendered for registration of transfer or exchange shall be accompanied by a written instrument of transfer in form satisfactory to the Trust Administrator duly executed by the holder thereof or his attorney duly authorized in writing.

No service charge to the Certificateholders shall be made for any registration of transfer or exchange of Certificates, but payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any transfer or exchange of Certificates may be required by the Trust Administrator.

All Certificates surrendered for registration of transfer or exchange shall be canceled and subsequently destroyed by the Trust Administrator in accordance with the Trust Administrator’s customary procedures.

(b)

(i) No transfer of a Private Certificate shall be made unless such transfer is made pursuant to an effective registration statement under the Securities Act and any applicable state securities laws or is exempt from the registration requirements under said Act and such state securities laws. In the event that a transfer is to be made in reliance upon an exemption from the Securities Act and such laws, in order to assure compliance with the Securities Act and such laws, the Certificateholder desiring to effect such transfer (other than the Depositor or an affiliate of the Depositor) shall certify to the Trust Administrator in writing the facts surrounding the transfer in substantially the form set forth in Exhibit J (the “Transferor Certificate”). Further, such Certificateholder’s prospective transferee will either (i) deliver a letter in substantially the form of either Exhibit K (the “Investment Letter”) or Exhibit L (the “Rule 144A Letter”) or (ii) deliver to the Trust Administrator at the expense of the transferor an Opinion of Counsel addressed to the Trust Administrator that such transfer may be made pursuant to an exemption from the Securities Act. The Depositor shall provide to any Holder of a Private Certificate and any prospective transferee designated by any such Holder, information regarding the related Certificates and the Mortgage Loans and such other information as shall be necessary to satisfy the condition to eligibility set forth in Rule 144A(d)(4) for transfer of any such Certificate without registration thereof under the Securities Act pursuant to the registration exemption provided by Rule 144A. The Trust Administrator and the Master Servicer shall cooperate with the Depositor, in accordance with the Depositor’s request, in providing the Rule 144A information referenced in the preceding sentence, including providing to the Depositor, to the extent in its possession, such information regarding the Certificates, the Mortgage Loans and other matters regarding the Trust Fund as the Depositor shall reasonably request to meet its obligation under the preceding sentence. Each Holder of a Private Certificate desiring to effect such transfer shall, and does hereby agree to, indemnify the Trustee, the Trust Administrator, the NIMS Insurer, the Depositor, and the Master Servicer against any liability that may result if the transfer is not so exempt or is not made in accordance with such federal and state laws.

(ii)

No transfer of an ERISA-Restricted Certificate shall be made (other than to the Depositor or an affiliate of the Depositor) unless the Trust Administrator shall have received in accordance with Exhibit K or Exhibit L (in the event such Certificate is a Private Certificate) or paragraph 13 of Exhibit I (in the event such Certificate is a Residual Certificate), in form and substance satisfactory to such Trust Administrator (i) a representation that such transferee is not an employee benefit plan or other retirement arrangement subject to Section 406 of ERISA and/or Section 4975 of the Code (a “Plan”), or a person acting for, on behalf of or with the assets of, any such Plan, (ii) in the case of an ERISA-Restricted Certificate which is the subject of an ERISA-Qualifying Underwriting, if the purchaser is an insurance company, a representation that the purchaser is an insurance company which is purchasing such Certificates with funds contained in an “insurance company general account” (as such term is defined in Section V(e) of Prohibited Transaction Class Exemption 95-60 (“PTCE 95-60”)) and that the purchase and holding of such Certificates are covered under Sections I and III of PTCE 95-60 or (iii) an Opinion of Counsel satisfactory to the Trust Administrator, which Opinion of Counsel shall not be an expense of the Trustee, the Trust Administrator, the NIMS Insurer, the Depositor, the Transferor, the Master Servicer or the Trust Fund, addressed to the Trust Administrator to the effect that the purchase or holding of such ERISA-Restricted Certificate will not result in non-exempt prohibited transactions under Section 406 of ERISA and/or Section 4975 of the Code and will not subject the Trustee, the Trust Administrator, the Depositor, the Transferor or the Master Servicer to any obligation in addition to those expressly undertaken in this Agreement. For purposes of the preceding sentence, with respect to an ERISA-Restricted Certificate that is not a Private Certificate or a Residual Certificate, in the event the representation letter referred to in the preceding sentence is not so furnished, such representation shall be deemed to have been made to the Trust Administrator by the transferee’s (including an initial acquirer’s) acceptance of the ERISA-Restricted Certificates. Notwithstanding anything else to the contrary herein, any purported transfer of an ERISA-Restricted Certificate, to or on behalf of a Plan in violation of the above restrictions shall be void and of no effect.

To the extent permitted under applicable law (including, but not limited to, ERISA), the Trust Administrator shall be under no liability to any Person for any registration of transfer of any ERISA-Restricted Certificate that is in fact not permitted by this Section 6.02(b) or for making any payments due on such Certificate to the Holder thereof or taking any other action with respect to such Holder under the provisions of this Agreement so long as the transfer was registered by the Trust Administrator in accordance with the foregoing requirements.

Neither the Trust Administrator nor the Master Servicer shall be required to monitor, determine or inquire as to the compliance with the transfer restrictions with respect to any ERISA Restricted Certificate that is a Book-Entry Certificate, and neither the Trust Administrator nor the Master Servicer shall have any liability for transfers of any such Book-Entry Certificates made through the book entry facilities of any Depository or between or among Depository Participants or Certificate Owners made in violation of the transfer restrictions set forth herein.

(iii)

No transfer of an ERISA-Restricted Trust Certificate prior to the termination of the Group I Cap 2 Agreement and the Group I Swap Agreement shall be made unless the Trust Administrator shall have received a representation letter from the transferee of such Certificate, substantially in the form set forth in Exhibit K or Exhibit L (or Exhibit I in the event such Certificate is a Residual Certificate), to the effect that either (i) such transferee is neither a Plan nor a Person acting on behalf of any such Plan or using the assets of any such Plan to effect such transfer or (ii) the acquisition and holding of the ERISA-Restricted Trust Certificate are eligible for exemptive relief under the statutory exemption for non-fiduciary service providers under Section 408(b)(17) of ERISA and Section 4975(d)(20) of the Code, Prohibited Transaction Class Exemption (“PTCE”) 84-14, XXXX 00-0, XXXX 00-00, XXXX 95-60 or PTCE 96-23 or some other applicable exemption. Notwithstanding anything else to the contrary herein, any purported transfer of an ERISA-Restricted Trust Certificate on behalf of a Plan without the delivery to the Trust Administrator of a representation letter as described above shall be void and of no effect. If the ERISA-Restricted Trust Certificate is a Book-Entry Certificate, the transferee will be deemed to have made a representation as provided in clause (i) or (ii) of this paragraph, as applicable.

If any ERISA-Restricted Trust Certificate, or any interest therein, is acquired or held in violation of the provisions of the preceding paragraph, the next preceding permitted beneficial owner will be treated as the beneficial owner of that Certificate, retroactive to the date of transfer to the purported beneficial owner. Any purported beneficial owner whose acquisition or holding of an ERISA-Restricted Trust Certificate, or interest therein, was effected in violation of the provisions of the preceding paragraph shall indemnify to the extent permitted by law and hold harmless the Trustee, the Trust Administrator, the Depositor, the Transferor or the Master Servicer from and against any and all liabilities, claims, costs or expenses incurred by such parties as a result of such acquisition or holding.

To the extent permitted under applicable law (including, but not limited to, ERISA), the Trust Administrator shall be under no liability to any Person for any registration of transfer of any ERISA-Restricted Trust Certificate that is in fact not permitted by this Section 6.02(b)(iii) or for making any payments due on such Certificate to the Holder thereof or taking any other action with respect to such Holder under the provisions of this Agreement so long as the transfer was registered by the Trust Administrator in accordance with the foregoing requirements.

(c)

Each Person who has or who acquires any Ownership Interest in a Residual Certificate shall be deemed by the acceptance or acquisition of such Ownership Interest to have agreed to be bound by the following provisions, and the rights of each Person acquiring any Ownership Interest in a Residual Certificate are expressly subject to the following provisions:

(i)

Each Person holding or acquiring any Ownership Interest in a Residual Certificate shall be a Permitted Transferee and shall promptly notify the Trust Administrator of any change or impending change in its status as a Permitted Transferee.

(ii)

No Ownership Interest in a Residual Certificate may be registered on the Closing Date or thereafter transferred, and the Trust Administrator shall not register the Transfer of any Residual Certificate unless, in addition to the certificates required to be delivered to the Trust Administrator under subparagraph (b) above, the Trust Administrator shall have been furnished with an affidavit (a “Transfer Affidavit”) of the initial owner or the proposed transferee (other than the Depositor of an affiliate thereof) in the form attached hereto as Exhibit I.

(iii)

Each Person holding or acquiring any Ownership Interest in a Residual Certificate shall agree (A) to obtain a Transfer Affidavit from any other Person to whom such Person attempts to Transfer its Ownership Interest in a Residual Certificate, (B) to obtain a Transfer Affidavit from any Person for whom such Person is acting as nominee, trustee or agent in connection with any Transfer of a Residual Certificate and (C) not to Transfer its Ownership Interest in a Residual Certificate or to cause the Transfer of an Ownership Interest in a Residual Certificate to any other Person if it has actual knowledge that such Person is not a Permitted Transferee.

(iv)

Any attempted or purported Transfer of any Ownership Interest in a Residual Certificate in violation of the provisions of this Section 6.02(c) shall be absolutely null and void and shall vest no rights in the purported transferee. If any purported transferee shall become a Holder of a Residual Certificate in violation of the provisions of this Section 6.02(c), then the last preceding Permitted Transferee shall be restored to all rights as Holder thereof retroactive to the date of registration of Transfer of such Residual Certificate. The Trust Administrator shall be under no liability to any Person for any registration of Transfer of a Residual Certificate that is in fact not permitted by Section 6.02(b) and this Section 6.02(c) or for making any payments due on such Certificate to the Holder thereof or taking any other action with respect to such Holder under the provisions of this Agreement so long as the Transfer was registered after receipt of the related Transfer Affidavit, Transferor Certificate and either the Rule 144A Letter or the Investment Letter. The Trust Administrator shall be entitled but not obligated to recover from any Holder of a Residual Certificate that was in fact not a Permitted Transferee at the time it became a Holder or, at such subsequent time as it became other than a Permitted Transferee, all payments made on such Residual Certificate at and after either such time. Any such payments so recovered by the Trust Administrator shall be paid and delivered by the Trust Administrator to the last preceding Permitted Transferee of such Certificate.

(v)

The Depositor shall use its best efforts to make available, upon receipt of written request from the Trust Administrator, all information necessary to compute any tax imposed under Section 860E(e) of the Code as a result of a Transfer of an Ownership Interest in a Residual Certificate to any Holder who is not a Permitted Transferee.

The restrictions on Transfers of a Residual Certificate set forth in this Section 6.02(c) shall cease to apply (and the applicable portions of the legend on a Residual Certificate may be deleted) with respect to Transfers occurring after delivery to the Trust Administrator of an Opinion of Counsel addressed to the Trust Administrator and the Master Servicer, which Opinion of Counsel shall not be an expense of the Trust Fund, the Trustee, the Trust Administrator, the NIMS Insurer, the Transferor or the Master Servicer, to the effect that the elimination of such restrictions will not cause any REMIC hereunder to fail to qualify as a REMIC at any time that the Certificates are outstanding or result in the imposition of any tax on the Trust Fund, a Certificateholder or another Person. Each Person holding or acquiring any Ownership Interest in a Residual Certificate hereby consents to any amendment of this Agreement which, based on an Opinion of Counsel furnished and addressed to the Trust Administrator, is reasonably necessary (a) to ensure that the record ownership of, or any beneficial interest in, a Residual Certificate is not transferred, directly or indirectly, to a Person that is not a Permitted Transferee and (b) to provide for a means to compel the Transfer of a Residual Certificate which is held by a Person that is not a Permitted Transferee to a Holder that is a Permitted Transferee.

(d)

The preparation and delivery of all certificates and opinions referred to above in this Section 6.02 in connection with transfer shall be at the expense of the parties to such transfers.

(e)

Except as provided below, the Book-Entry Certificates shall at all times remain registered in the name of the Depository or its nominee and at all times: (i) registration of the Certificates may not be transferred by the Trust Administrator except to another Depository; (ii) the Depository shall maintain Book-Entry records with respect to the Certificate Owners and with respect to ownership and transfers of such Book-Entry Certificates; (iii) ownership and transfers of registration of the Book-Entry Certificates on the books of the Depository shall be governed by applicable rules established by the Depository; (iv) the Depository may collect its usual and customary fees, charges and expenses from its Depository Participants; (v) the Trust Administrator shall deal with the Depository as representative of the Certificate Owners of the Book-Entry Certificates for purposes of exercising the rights of Holders under this Agreement, and requests and directions for and votes of such representative shall not be deemed to be inconsistent if they are made with respect to different Certificate Owners; and (vi) the Trust Administrator may conclusively rely and shall be fully protected in relying upon information furnished by the Depository with respect to its Depository Participants and furnished by the Depository Participants with respect to indirect participating firms and persons shown on the books of such indirect participating firms as direct or indirect Certificate Owners.

All transfers by Certificate Owners of Book-Entry Certificates shall be made in accordance with the procedures established by the Depository Participant or brokerage firm representing such Certificate Owner. Each Depository Participant shall only transfer Book-Entry Certificates of Certificate Owners it represents or of brokerage firms for which it acts as agent in accordance with the Depository’s normal procedures.

If (x) (i) the Depository or the Depositor advises the Trust Administrator in writing that the Depository is no longer willing, qualified or able to properly discharge its responsibilities as Depository, and (ii) the Depositor is unable to locate a qualified successor, (y) the Depositor notifies the Trust Administrator in writing, with the consent of the applicable Depository Participants, that it elects to terminate the book-entry system through the Depository or (z) after the occurrence of a Master Servicer Event of Termination, Certificate Owners representing at least 51% of the Certificate Principal Balance of the Book-Entry Certificates together advise the Trust Administrator and the Depository through the Depository Participants in writing that the continuation of a Book-Entry system through the Depository is no longer in the best interests of the Certificate Owners and the Depository Participants consent to the termination, the Trust Administrator, upon receipt of notice of such event, shall notify all Certificate Owners, through the Depository, of the occurrence of any such event and of the availability of definitive, fully-registered Certificates (the “Definitive Certificates”) to Certificate Owners requesting the same. Upon surrender to the Trust Administrator of the related Class of Certificates by the Depository, accompanied by the instructions from the Depository for registration, the Trust Administrator shall issue the Definitive Certificates. None of the Master Servicer, the Depositor nor the Trust Administrator shall be liable for any delay in delivery of such instruction and each may conclusively rely on, and shall be protected in relying on, such instructions. The Depositor shall provide the Trust Administrator with an adequate inventory of certificates to facilitate the issuance and transfer of Definitive Certificates. Upon the issuance of Definitive Certificates all references herein to obligations imposed upon or to be performed by the Depository shall be deemed to be imposed upon and performed by the Trust Administrator, to the extent applicable with respect to such Definitive Certificates and the Trust Administrator shall recognize the Holders of the Definitive Certificates as Certificateholders hereunder; provided that the Trust Administrator shall not by virtue of its assumption of such obligations become liable to any party for any act or failure to act of the Depository.

Section 6.03. Mutilated, Destroyed, Lost or Stolen Certificates.

If (a) any mutilated Certificate is surrendered to the Trust Administrator, or the Trust Administrator receives evidence to its satisfaction of the destruction, loss or theft of any Certificate and (b) there is delivered to the Master Servicer, the NIMS Insurer and the Trust Administrator such security or indemnity as may be required by them to save each of them harmless, then, in the absence of notice to the Trust Administrator that such Certificate has been acquired by a bona fide purchaser, the Trust Administrator shall execute, countersign and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a new Certificate of like Class, tenor and Percentage Interest. In connection with the issuance of any new Certificate under this Section 6.03, the Trust Administrator may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trust Administrator and its counsel) connected therewith. Any replacement Certificate issued pursuant to this Section 6.03 shall constitute complete and indefeasible evidence of ownership, as if originally issued, whether or not the lost, stolen or destroyed Certificate shall be found at any time.

Section 6.04. Persons Deemed Owners.

The Master Servicer, the Trustee, the Trust Administrator, the NIMS Insurer and any agent of the Master Servicer, the Trust Administrator or the Trustee may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions as provided in this Agreement and for all other purposes whatsoever, and none of the Master Servicer, the Trust Administrator, the NIMS Insurer or the Trustee nor any agent of the Master Servicer, the Trust Administrator, the NIMS Insurer or the Trustee shall be affected by any notice to the contrary.

Section 6.05. Access to List of Certificateholders’ Names and Addresses.

If three or more Certificateholders (a) request such information in writing from the Trust Administrator, (b) state that such Certificateholders desire to communicate with other Certificateholders with respect to their rights under this Agreement or under the Certificates, and (c) provide a copy of the communication which such Certificateholders propose to transmit, or if the Depositor or Master Servicer shall request such information in writing from the Trust Administrator, then the Trust Administrator shall, within ten Business Days after the receipt of such request, provide the Depositor, the Master Servicer or such Certificateholders at such recipients’ expense the most recent list of the Certificateholders of such Trust Fund held by the Trust Administrator, if any. The Depositor and every Certificateholder, by receiving and holding a Certificate, agree that the Trust Administrator shall not be held accountable by reason of the disclosure of any such information as to the list of the Certificateholders hereunder, regardless of the source from which such information was derived.

Section 6.06. Maintenance of Office or Agency.

Certificates may be surrendered for registration of transfer or exchange at Corporate Trust Office of the Trust Administrator. The Trust Administrator will give prompt written notice to the Certificateholders of any change in such location of any such office or agency.

Section 6.07. Deposit of Uncertificated REMIC Interests.

The Uncertificated REMIC Interests shall be issued in uncertificated form to the Underwriter pursuant to Section 4 of the Underwriting Agreement and transferred by the Underwriter on the Closing Date to the Trustee to be held in trust pursuant to terms of the Trust Agreement. U.S. Bank National Association, as Trustee, and Xxxxx Fargo Bank, N.A., as Trust Administrator, are hereby directed and authorized to enter into the Trust Agreement. In entering into the Trust Agreement and performing its obligations thereunder, each of the Trustee and the Trust Administrator shall be entitled to the same rights, protections and indemnities afforded to them under this Agreement in their capacities as Trustee and Trust Administrator, respectively.

(iii)

There is entered against the Master Servicer a decree or order by a court or agency or supervisory authority having jurisdiction in the premises for the appointment of a conservator, receiver or liquidator in any insolvency, readjustment of debt, marshaling of assets and liabilities or similar proceedings, or for the winding up or liquidation of its affairs, and the continuance of any such decree or order is unstayed and in effect for a period of 60 consecutive days, or an involuntary case is commenced against the Master Servicer under any applicable insolvency or reorganization statute and the petition is not dismissed within 60 days after the commencement of the case; or

(iv)

The Master Servicer consents to the appointment of a conservator or receiver or liquidator in any insolvency, readjustment of debt, marshaling of assets and liabilities or similar proceedings of or relating to the Master Servicer or substantially all of its property; or the Master Servicer admits in writing its inability to pay its debts generally as they become due, files a petition to take advantage of any applicable insolvency or reorganization statute, makes an assignment for the benefit of its creditors, or voluntarily suspends payment of its obligations; or

The termination of the rights and obligations of the Master Servicer shall not affect any obligations incurred by the Master Servicer prior to such termination.

Notwithstanding any termination of the activities of the Master Servicer hereunder, the Master Servicer shall be entitled to receive, out of any late collection of a Scheduled Payment on a Mortgage Loan which was due prior to the notice terminating such Master Servicer’s rights and obligations as Master Servicer hereunder and received after such notice, that portion thereof to which such Master Servicer would have been entitled pursuant to Sections 3.10(a)(i) through (xi), and any other amounts payable to such Master Servicer hereunder the entitlement to which arose prior to the termination of its activities hereunder.

On and after the time the Master Servicer receives a notice of termination pursuant to Section 8.01 hereof, the Trustee shall, subject to and to the extent provided in Section 3.05, be the successor to the Master Servicer in its capacity as Master Servicer under this Agreement and the transactions set forth or provided for herein and shall be subject to all the responsibilities, duties, liabilities and limitations on liabilities relating thereto placed on the Master Servicer by the terms and provisions hereof and applicable law, including the obligation to make Advances pursuant to Section 5.10. As compensation therefor, the Trustee shall be entitled to investment income on all funds to which the Master Servicer would have been entitled in the Collection Account or Distribution Account if the Master Servicer had continued to act hereunder. Notwithstanding the foregoing, if the Trustee has become the successor to the Master Servicer in accordance with Section 8.01 hereof, the Trustee may, if it shall be unwilling to so act, or shall, if it is prohibited by applicable law from making Advances pursuant to Section 5.10 hereof or if it is otherwise unable to so act, or if it has been requested in writing by the NIMS Insurer or Holders of Certificates evidencing not less than 25% of the Voting Rights evidenced by the Certificates to do so, appoint, or petition a court of competent jurisdiction to appoint, any established mortgage loan servicing institution the appointment of which does not adversely affect the then current rating of the Certificates by each Rating Agency as the successor to the Master Servicer hereunder in the assumption of all or any part of the responsibilities, duties or liabilities of the Master Servicer hereunder. Any successor to the Master Servicer shall be an institution which is a Xxxxxx Xxx and Xxxxxxx Mac approved seller/servicer in good standing, which has a net worth of at least $15,000,000, and which is willing to master service the Mortgage Loans and executes and delivers to the Depositor and the Trustee an agreement accepting such delegation and assignment, which contains an assumption by such Person of the rights, powers, duties, responsibilities, obligations and liabilities of the Master Servicer (other than liabilities of the Master Servicer under Section 7.03 hereof incurred prior to termination of the Master Servicer under Section 8.01), with like effect as if originally named as a party to this Agreement; and provided further that each Rating Agency acknowledges that its rating of the Certificates in effect immediately prior to such assignment and delegation will not be qualified or reduced, without regard to the guaranty provided by the Policies, as a result of such assignment and delegation. Pending appointment of a successor to the Master Servicer hereunder, the Trustee, unless the Trustee is prohibited by law from so acting, shall, subject to Section 3.05 hereof, act in such capacity as hereinabove provided. In connection with such appointment and assumption, the Trustee may make such arrangements for the compensation of such successor master servicer out of payments on Mortgage Loans as it and such successor master servicer shall agree; provided, however, that no such compensation shall be in excess of the compensation permitted the Master Servicer hereunder. The Trustee and such successor master servicer shall take such action, consistent with this Agreement, as shall be necessary to effectuate any such succession. Neither the Trustee nor any other successor master servicer shall be deemed to be in default hereunder by reason of any failure to make, or any delay in making, any distribution hereunder or any portion thereof or any failure to perform, or any delay in performing, any duties or responsibilities hereunder, in either case caused by the failure of the Master Servicer to deliver or provide, or any delay in delivering or providing, any cash, information, documents or records to it.

Any successor master servicer as Master Servicer shall give notice to each Servicer of such change of master servicer and shall, during the term of its service as master servicer enforce the requirement of each Servicer to maintain in force the policy or policies pursuant to Section 3.11.

The Trustee or successor master servicer shall be entitled to be reimbursed from the Master Servicer for all costs associated with the transfer of master servicing from the predecessor master servicer, including, without limitation, any costs or expenses (including but not limited to personnel time) associated with the complete transfer of all master servicing data and the completion, correction or manipulation of such master servicing data as may be required by the Trustee or successor master servicer to correct any errors or insufficiencies in the master servicing data or otherwise to enable the Trustee or successor master servicer to master service the Mortgage Loans properly and effectively. If the Master Servicer does not pay such reimbursement within thirty (30) days of its receipt of an invoice therefor, such reimbursement shall be an expense of the Trust and the Trustee shall be entitled to withdraw such reimbursement from amounts on deposit in the Distribution Account pursuant to Section 3.10(b)(iii); provided that the Master Servicer shall reimburse the Trust for any such expense incurred by the Trust.

Section 8.03. Notification to Certificateholders.

(a)

Upon any termination of or appointment of a successor to the Master Servicer, the Trustee (or the Trust Administrator on its behalf) shall give prompt written notice thereof to the NIMS Insurer, the Group I Certificate Insurer, Certificateholders and to each Rating Agency.

(b)

Within 60 days after the occurrence of any Master Servicer Event of Termination, the Trustee or the Trust Administrator shall transmit by mail to the NIMS Insurer, the Group I Certificate Insurer and all Certificateholders notice of each such Master Servicer Event of Termination hereunder actually known to a Responsible Officer of the Trustee or the Trust Administrator, unless such Master Servicer Event of Termination shall have been cured or waived.

ARTICLE IX

CONCERNING THE TRUSTEE AND THE MASTER SERVICER

Section 9.01. Duties of Trustee.

The Trustee, prior to the occurrence of a Master Servicer Event of Termination and after the curing or waiver of all Master Servicer Events of Termination that may have occurred, shall undertake to perform such duties and only such duties as are specifically set forth in this Agreement. In case a Master Servicer Event of Termination has occurred and remains uncured or unwaived, the Trustee shall exercise such of the rights and powers vested in it by this Agreement, and use the same degree of care and skill in their exercise as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs, but only until such time as a successor Master Servicer shall have been appointed hereunder.

The Trustee, upon receipt of all resolutions, certificates, statements, opinions, reports, documents, orders or other instruments furnished to the Trustee that are specifically required to be furnished pursuant to any provision of this Agreement shall examine them to determine whether they are in the form required by this Agreement to the extent that forms of such documents have been provided to the Trustee; provided, however, that the Trustee shall not be responsible for the accuracy or content of any such resolution, certificate, statement, opinion, report, document, order or other instrument. If any such instrument is found not to conform in any material respect to the requirements of this Agreement, the Trustee shall notify the NIMS Insurer, the Group I Certificate Insurer and the Certificateholders of such non-conforming instrument in the event the Trustee, after so requesting, does not receive a satisfactorily corrected instrument.

No provision of this Agreement shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act or its own willful misconduct; provided, however, that:

(i)

unless a Master Servicer Event of Termination of which a Responsible Officer of the Trustee has actual knowledge shall have occurred and be continuing, the duties and obligations of the Trustee shall be determined solely by the express provisions of this Agreement, the Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in this Agreement, no implied covenants or obligations shall be read into this Agreement against the Trustee and the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee and conforming to the requirements of this Agreement which it believed in good faith to be genuine and to have been duly executed by the proper authorities respecting any matters arising hereunder;

(ii)

the Trustee shall not be liable for an error of judgment made in good faith by a Responsible Officer or Responsible Officers of the Trustee, unless it shall be conclusively determined by a court of competent jurisdiction, such determination no longer subject to appeal, that the Trustee was negligent in ascertaining the pertinent facts;

(iii)

the Trustee shall not be liable with respect to any action taken, suffered or omitted to be taken by it in good faith in accordance with the direction of the NIMS Insurer or Holders of Certificates evidencing not less than 25% of the Voting Rights of Certificates relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising or omitting to exercise any trust or power conferred upon the Trustee under this Agreement;

(iv)

the Trustee shall not be accountable, shall have no liability and makes no representation as to any acts or omissions hereunder of the Master Servicer until such time as the Trustee may be required to act as Master Servicer pursuant to Section 8.02 and thereupon only for the acts or omissions of the Trustee as successor Master Servicer; and

(v)

the Trustee shall promptly remit to the Master Servicer any complaint, claim, demand, notice or other document (collectively, the “Notices”) delivered to the Trustee as a consequence of the assignment of any Mortgage Loan hereunder and relating to the servicing of the Mortgage Loans; provided that any such Notice (i) is delivered to the Trustee at its Corporate Trust Office; and (ii) contains information sufficient to permit the Trustee to make a determination that the real property to which such document relates is a Mortgaged Property. The Trustee shall have no duty hereunder with respect to any Notice it may receive or which may be alleged to have been delivered to or served upon it unless such Notice is delivered to it or served upon it at its Corporate Trust Office and such Notice contains the information required pursuant to clause (ii) of the preceding sentence.

Section 9.02. Certain Matters Affecting the Trustee.

(a)

Except as otherwise provided in Section 9.01:

(i)

the Trustee may request and conclusively rely upon and shall be fully protected in acting or refraining from acting upon any resolution, Officer’s Certificate, certificate of auditors or any other certificate, statement, instrument, opinion, report, notice, request, consent, order, appraisal, bond or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties and the Trustee shall have no responsibility to ascertain or confirm the genuineness of any signature of any such party or parties;

(ii)

the Trustee may consult with counsel, financial advisers or accountants and the advice of any such counsel, financial advisers or accountants and any advice or Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken or suffered or omitted by it hereunder in good faith and in accordance with such advice or Opinion of Counsel;

(iii)

the Trustee shall not be liable for any action taken, suffered or omitted by it in good faith and believed by it to be authorized or within the discretion or rights or powers conferred upon it by this Agreement;

(iv)

prior to the occurrence of a Master Servicer Event of Termination and after the curing or waiver of all Master Servicer Events of Termination which may have occurred, the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, approval, bond or other paper or document, unless requested in writing so to do by the NIMS Insurer or Holders of Certificates evidencing not less than 25% of the Voting Rights allocated to each Class of Certificates; provided, however, that if the payment within a reasonable time to the Trustee of the costs, expenses or liabilities likely to be incurred by it in the making of such investigation is, in the opinion of the Trustee, not reasonably assured to the Trustee by the security afforded to it by the terms of this Agreement, the Trustee may require reasonable indemnity against such expense or liability as a condition to so proceeding. The reasonable expense of every such examination shall be paid by the Master Servicer or, if paid by the Trustee, shall be reimbursed by the Master Servicer upon demand. Nothing in this clause (iv) shall derogate from the obligation of the Master Servicer to observe any applicable law prohibiting disclosure of information regarding the Mortgagors;

(v)

the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys or a custodian (including, without limitation, the Custodian) and the Trustee shall not be responsible for any misconduct or negligence on the part of any such agent, attorney or custodian appointed by the Trustee with due care or on the part of the Custodian;

(vi)

the Trustee shall not be required to risk or expend its own funds or otherwise incur any financial liability in the performance of any of its duties or in the exercise of any of its rights or powers hereunder if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not assured to it, and none of the provisions contained in this Agreement shall in any event require the Trustee to perform, or be responsible for the manner of performance of, any of the obligations of the Master Servicer under this Agreement, except during such time, if any, as the Trustee shall be the successor to, and be vested with the rights, duties, powers and privileges of, the Master Servicer in accordance with the terms of this Agreement;

(vii)

the Trustee shall not be liable for any loss on any investment of funds pursuant to this Agreement (other than as issuer of the investment security);

(viii)

the Trustee shall not be deemed to have knowledge of a Master Servicer Event of Termination until a Responsible Officer of the Trustee obtains actual knowledge of such failure or the Trustee receives written notice of such failure from the Master Servicer, the NIMS Insurer, the Group I Certificate Insurer or the holders of Certificates evidencing not less than 25% of the Voting Rights of Certificates. In the absence of such receipt of such notice, the Trustee may conclusively assume that there is no Master Servicer Event of Termination;

(ix)

the Trustee shall be under no obligation to exercise any of the trusts, rights or powers vested in it by this Agreement or to institute, conduct or defend any litigation hereunder or in relation hereto at the request, order or direction of any of the NIMS Insurer or the Certificateholders, pursuant to the provisions of this Agreement, unless the NIMS Insurer, the Group I Certificate Insurer or the Certificateholders have offered to the Trustee reasonable security or indemnity satisfactory to the Trustee against the costs, expenses and liabilities which may be incurred therein or thereby.

(b)

The Trustee shall have no duty (A) to see to any recording, filing, or depositing of this Agreement or any agreement referred to herein or any financing statement or continuation statement evidencing a security interest, or to see to the maintenance of any such recording or filing or depositing or to any rerecording, refiling or redepositing thereof, (B) to see to the provision of any insurance or (C) to see to the payment or discharge of any tax, assessment, or other governmental charge or any lien or encumbrance of any kind owing with respect to, assessed or levied against, any part of the Trust Fund other than from funds available in the Distribution Account.

Section 9.03. Trustee Not Liable for Certificates or Mortgage Loans.

The recitals contained herein and in the Certificates shall be taken as the statements of the Depositor or the Transferor, as the case may be, and the Trustee assumes no responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of this Agreement or of the Certificates or of any Mortgage Loan or related document. The Trustee shall not be accountable for the use or application by the Depositor or the Master Servicer of any funds paid to the Depositor or the Master Servicer in respect of the Mortgage Loans or deposited in or withdrawn from the Collection Account or the Distribution Account by the Depositor, the Master Servicer or the Trust Administrator.

Section 9.04. Trustee May Own Certificates.

The Trustee in its individual or any other capacity may become the owner or pledgee of Certificates and may transact business with the parties hereto and their Affiliates with the same rights as it would have if it were not the Trustee.

Section 9.05. Trustee’s Fees and Expenses.

The Trustee shall be compensated by the Master Servicer as separately agreed with the Master Servicer. The Trustee and any director, officer, employee, agent or “control person” within the meaning of the Securities Act of 1933, as amended, and the Securities Exchange of 1934, as amended (“Control Person”), of the Trustee shall be indemnified by the Trust and held harmless against any loss, liability or expense (including reasonable attorney’s fees) (i) incurred in connection with any claim or legal action relating to (a) this Agreement (b) the Mortgage Loans or (c) the Certificates, other than any loss, liability or expense incurred by reason of willful misfeasance, bad faith or negligence in the performance of any of the Trustee’s duties hereunder, (ii) incurred in connection with the performance of any of the Trustee’s duties or the exercise of (or failure to exercise) its rights hereunder, other than any loss, liability or expense incurred by reason of willful misfeasance, bad faith or negligence in the performance of any of the Trustee’s duties hereunder, or in the exercise (or failure to exercise) any of the Trustee’s rights hereunder, (iii) incurred by reason of any action of the Trustee taken at the direction of the Certificateholders, or (iv) resulting from any error in any tax or information return prepared by the Master Servicer, provided, that any such loss, liability or expense constitutes an “unanticipated expense incurred by the REMIC” within the meaning of Treasury Regulations Section 1.860G-1(b)(3)(ii). Such indemnity shall survive the termination of this Agreement or the resignation or removal of the Trustee hereunder. Without limiting the foregoing, and except for any such expense, disbursement or advance as may arise from the Trustee’s negligence, bad faith or willful misconduct, or which would not be an “unanticipated expense” within the meaning of the second preceding sentence, the Trustee shall be reimbursed by the Trust for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any of the provisions of this Agreement with respect to: (A) the reasonable compensation and the expenses and disbursements of its counsel not associated with the closing of the issuance of the Certificates, (B) the reasonable compensation, expenses and disbursements of any accountant, engineer, appraiser or other agent that is not regularly employed by the Trustee, to the extent that the Trustee must engage such Persons to perform acts or services hereunder and (C) printing and engraving expenses in connection with preparing any Definitive Certificates. The Trust shall fulfill its obligations under this paragraph from amounts on deposit from time to time in the Distribution Account.

Section 9.06. Eligibility Requirements for Trustee.

The Trustee hereunder shall at all times be a corporation or association organized and doing business under the laws of the United States of America or any state thereof, authorized under such laws to exercise corporate trust powers, having a combined capital and surplus of at least $50,000,000, subject to supervision or examination by federal or state authority and with a credit rating of at least investment grade. If such corporation or association publishes reports of condition at least annually, pursuant to law or to the requirements of the aforesaid supervising or examining authority, then for the purposes of this Section 9.06 the combined capital and surplus of such corporation or association shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. In case at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section 9.06, the Trustee shall resign immediately in the manner and with the effect specified in Section 9.07 hereof. The entity serving as Trustee may have normal banking and trust relationships with the Depositor and its affiliates or the Master Servicer and its affiliates; provided, however, that such entity cannot be an affiliate of the Master Servicer other than the Trustee in its role as successor to the Master Servicer.

Section 9.07. Resignation and Removal of Trustee.

The Trustee may at any time resign and be discharged from the trusts hereby created by giving written notice of resignation to the Depositor, the NIMS Insurer, the Group I Certificate Insurer and the Master Servicer and each Rating Agency not less than 60 days before the date specified in such notice when, subject to Section 9.08, such resignation is to take effect, and acceptance by a successor trustee acceptable to the NIMS Insurer and the Group I Certificate Insurer and in accordance with Section 9.08 meeting the qualifications set forth in Section 9.06. If no successor trustee meeting such qualifications shall have been so appointed by the Depositor and have accepted appointment within 30 days after the giving of such notice of resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor trustee.

If at any time the Trustee shall cease to be eligible in accordance with the provisions of Section 9.06 hereof and shall fail to resign after written request thereto by the NIMS Insurer or the Depositor, or if at any time the Trustee shall become incapable of acting, or shall be adjudged as bankrupt or insolvent, or a receiver of the Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, or a tax is imposed with respect to the Trust Fund by any state in which the Trustee or the Trust Fund is located and the imposition of such tax would be avoided by the appointment of a different trustee, then the NIMS Insurer, the Group I Certificate Insurer, the Depositor or the Master Servicer may remove the Trustee and appoint a successor trustee acceptable to the NIMS Insurer and the Group I Certificate Insurer, by written instrument, in triplicate, one copy of which instrument shall be delivered to the Trustee so removed, one copy of which shall be delivered to the Master Servicer and one copy to the successor trustee.

The Holders of Certificates entitled to at least 51% of the Voting Rights or the NIMS Insurer may at any time remove the Trustee and appoint a successor trustee acceptable to the NIMS Insurer and the Group I Certificate Insurer, by written instrument or instruments, in triplicate, signed by such Holders or their attorneys-in-fact duly authorized, one complete set of which instruments shall be delivered by the successor Trustee to the Master Servicer, one complete set to the Trustee so removed and one complete set to the successor so appointed. Notice of any removal of the Trustee shall be given to each Rating Agency by the successor trustee.

Any resignation or removal of the Trustee and appointment of a successor trustee pursuant to any of the provisions of this Section 9.07 shall become effective upon acceptance by the successor trustee of appointment as provided in Section 9.08 hereof.

Section 9.08. Successor Trustee.

Any successor trustee appointed as provided in Section 9.07 hereof shall execute, acknowledge and deliver to the Depositor, the Group I Certificate Insurer, the NIMS Insurer and to its predecessor trustee and the Master Servicer an instrument accepting such appointment hereunder and thereupon the resignation or removal of the predecessor trustee shall become effective and such successor trustee, without any further act, deed or conveyance, shall become fully vested with all the rights, powers, duties and obligations of its predecessor hereunder, with the like effect as if originally named as trustee herein. The Depositor, the Master Servicer and the predecessor trustee shall execute and deliver such instruments and do such other things as may reasonably be required for more fully and certainly vesting and confirming in the successor trustee all such rights, powers, duties, and obligations.

No successor trustee shall accept appointment as provided in this Section 9.08 unless at the time of such acceptance such successor trustee shall be eligible under the provisions of Section 9.06 hereof and its appointment shall not adversely affect the then current rating of the Certificates, as confirmed in writing by each Rating Agency.

Upon acceptance by a successor trustee of appointment as provided in this Section 9.08, the Depositor shall mail notice of the succession of such trustee hereunder to all Holders of Certificates and the Group I Certificate Insurer. If the Depositor fails to mail such notice within 10 days after acceptance by the successor trustee of appointment, the successor trustee shall cause such notice to be mailed at the expense of the Depositor.

Section 9.09. Merger or Consolidation of Trustee.

Any corporation or other entity into which the Trustee may be merged or converted or with which it may be consolidated or any corporation or other entity resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation or other entity succeeding to the business of the Trustee, shall be the successor of the Trustee hereunder, provided that such corporation or other entity shall be eligible under the provisions of Section 9.06 hereof, without the execution or filing of any paper or further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding.

Section 9.10. Appointment of Co-Trustee or Separate Trustee.

Notwithstanding any other provisions of this Agreement, at any time, for the purpose of meeting any legal requirements of any jurisdiction in which any part of the Trust Fund or property securing any Mortgage Note may at the time be located, the Master Servicer and the Trustee acting jointly shall have the power and shall execute and deliver all instruments to appoint one or more Persons approved by the Trustee, the Group I Certificate Insurer and the NIMS Insurer to act as co-trustee or co-trustees jointly with the Trustee, or separate trustee or separate trustees, of all or any part of the Trust Fund, and to vest in such Person or Persons, in such capacity and for the benefit of the Certificateholders, such title to the Trust Fund or any part thereof, whichever is applicable, and, subject to the other provisions of this Section 9.10, such powers, duties, obligations, rights and trusts as the Master Servicer, the NIMS Insurer, the Group I Certificate Insurer and the Trustee may consider necessary or desirable. If the Master Servicer, the Group I Certificate Insurer or the NIMS Insurer shall not have joined in such appointment within 15 days after the receipt by it of a request to do so, or in the case where a Master Servicer Event of Termination and a Certificate Insurer Default shall have occurred and be continuing, the Trustee alone shall have the power to make such appointment. No co-trustee or separate trustee hereunder shall be required to meet the terms of eligibility as a successor trustee under Section 9.06 and no notice to Certificateholders of the appointment of any co-trustee or separate trustee shall be required under Section 9.08.

Every separate trustee and co-trustee shall, to the extent permitted by law, be appointed and act subject to the following provisions and conditions:

(i)

To the extent necessary to effectuate the purposes of this Section 9.10, all rights, powers, duties and obligations conferred or imposed upon the Trustee, except for the obligation of the Trustee (as successor master servicer) under this Agreement to advance funds on behalf of the Master Servicer, shall be conferred or imposed upon and exercised or performed by the Trustee and such separate trustee or co-trustee jointly (it being understood that such separate trustee or co-trustee is not authorized to act separately without the Trustee joining in such act), except to the extent that under any law of any jurisdiction in which any particular act or acts are to be performed (whether as Trustee hereunder or as successor to the Master Servicer hereunder), the Trustee shall be incompetent or unqualified to perform such act or acts, in which event such rights, powers, duties and obligations (including the holding of title to the applicable Trust Fund or any portion thereof in any such jurisdiction) shall be exercised and performed singly by such separate trustee or co-trustee, but solely at the direction of the Trustee;

(ii)

No trustee hereunder shall be held personally liable by reason of any act or omission of any other trustee hereunder and such appointment shall not, and shall not be deemed to, constitute any such separate trustee or co-trustee as agent of the Trustee; and

(iii)

The Trustee may at any time accept the resignation of or remove any separate trustee or co-trustee.

Any notice, request or other writing given to the Trustee shall be deemed to have been given to each of the separate trustees and co-trustees, when and as effectively as if given to each of them. Every instrument appointing any separate trustee or co-trustee shall refer to this Agreement and the conditions of this Article VIII. Each separate trustee and co-trustee, upon its acceptance of the trusts conferred, shall be vested with the estates or property specified in its instrument of appointment, either jointly with the Trustee or separately, as may be provided therein, subject to all the provisions of this Agreement, specifically including every provision of this Agreement relating to the conduct of, affecting the liability of, or affording protection to, the Trustee. Every such instrument shall be filed with the Trustee and a copy thereof given to the Master Servicer, the NIMS Insurer, the Group I Certificate Insurer and the Depositor.

Any separate trustee or co-trustee may, at any time, constitute the Trustee its agent or attorney-in-fact, with full power and authority, to the extent not prohibited by law, to do any lawful act under or in respect of this Agreement on its behalf and in its name. If any separate trustee or co-trustee shall die, become incapable of acting, resign or be removed, all of its estates, properties, rights, remedies and trusts shall vest in and be exercised by the Trustee, to the extent permitted by law, without the appointment of a new or successor trustee.

Section 10.10. [Reserved].

Section 10.11. Tax Matters.

It is intended that the assets with respect to which each REMIC election is to be made, as set forth in the Preliminary Statement, shall constitute, and that the conduct of matters relating to such assets shall be such as to qualify such assets as, a “real estate mortgage investment conduit” as defined in and in accordance with the REMIC Provisions. In furtherance of such intention, the Master Servicer covenants and agrees that it shall act as agent (and the Master Servicer is hereby appointed to act as agent) on behalf of each REMIC and that in such capacity it shall:

(a)

prepare, submit to the Trustee for execution, and file, or cause to be prepared and filed, in a timely manner, a U.S. Real Estate Mortgage Investment Conduit (REMIC) Income Tax Return (Form 1066 or any successor form adopted by the Internal Revenue Service) and prepare and file or cause to be prepared and filed with the Internal Revenue Service and applicable state or local tax authorities income tax or information returns for each taxable year with respect to such REMIC, containing such information and at the times and in the manner as may be required by the Code or state or local tax laws, regulations, or rules, and furnish or cause to be furnished to Certificateholders the schedules, statements or information at such times and in such manner as may be required thereby, including without limitation, the calculation of any original issue discount using the prepayment assumption identified in the Prospectus Supplement;

(b)

apply for an Employee Identification Number from the Internal Revenue Service via Form SS-4 or other acceptable method for such REMIC and within thirty days of the Closing Date, furnish or cause to be furnished to the Internal Revenue Service, on Form 8811 or as otherwise may be required by the Code, the name, title, address, and telephone number of the person that the holders of the Certificates may contact for tax information relating thereto, together with such additional information as may be required by such Form, and update such information at the time or times in the manner required by the Code;

(c)

make or cause to be made elections that such assets be treated as a REMIC on the federal tax return for its first taxable year (and, if necessary, under applicable state law);

(d)

provide information necessary for the computation of tax imposed on the transfer of a Residual Certificate to a Person that is not a Permitted Transferee described in clauses (i)-(iv) of the definition thereof, or an agent (including a broker, nominee or other middleman) of a non Permitted Transferee (the reasonable cost of computing and furnishing such information may be charged to the Person liable for such tax);

(e)

to the extent that they are under its control, conduct matters relating to such assets at all times that any Certificates are outstanding so as to maintain the status as a REMIC under the REMIC Provisions;

(f)

not knowingly or intentionally take any action or omit to take any action that would cause the termination of the REMIC status;

(g)

not permit the creation of any interests in such REMIC other than the Certificates;

(h)

not receive any amount representing a fee or other compensation for services (except as otherwise permitted by this Agreement);

(i)

receive any income attributable to any asset which is neither a “qualified mortgage” nor a “permitted investment” within the meaning of the REMIC Provisions;

(j)

not receive any contributions to such REMIC after the Startup Day that would be subject to tax under Section 860G(d) of the Code;

(k)

not dispose of any assets of such REMIC at a gain if such disposition would be a “prohibited transaction” within the meaning of Section 860F(a)(2) of the Code;

(l)

pay, from the sources specified in the last paragraph of this Section 10.11, the amount of any federal or state tax, including prohibited transaction taxes as described below, imposed on such REMIC prior to its termination when and as the same shall be due and payable (but such obligation shall not prevent the Master Servicer or any other appropriate Person from contesting any such tax in appropriate proceedings and shall not prevent the Master Servicer from causing the withholding of payment of such tax, if permitted by law, pending the outcome of such proceedings);

(m)

ensure that federal, state or local income tax or information returns shall be signed by the Trustee or such other Person as may be required to sign such returns by the Code or state or local laws, regulations or rules; and

(n)

maintain records relating to such REMIC, including but not limited to the income, expenses, assets and liabilities thereof and the adjusted basis of the assets determined at such intervals as may be required by the Code, as may be necessary to prepare the foregoing returns, schedules, statements or information.

The holder of the largest percentage interest in the Class R-X Certificates shall act as Tax Matters Person for the Class I-C and Class I-P REMICs. The holder of the largest percentage interest in the Class I-R Certificates shall act as Tax Matters Person for each remaining REMIC, in each case, within the meaning of Treasury Regulations Section 1.860F-4(d). The Master Servicer is hereby designated as agent of such Certificateholder for such purpose (or if the Master Servicer is not so permitted, such Holder shall be the Tax Matters Person in accordance with the REMIC Provisions). In such capacity, the Master Servicer shall, as and when necessary and appropriate, represent the related REMIC in any administrative or judicial proceedings relating to an examination or audit by any governmental taxing authority, request an administrative adjustment as to any taxable year of such REMIC, enter into settlement agreements with any governmental taxing agency, extend any statute of limitations relating to any tax item of such REMIC, and otherwise act on behalf of such REMIC in relation to any tax matter or controversy involving it.

For federal income tax purposes, the Trust Administrator shall treat the Holders of the Group I Certificates (other than the Class I-P, Class I-C, Class R-X, and Class I-R Certificates) as having entered into a notional principal contract with respect to the Holders of the Class I-C Certificates. Pursuant to each such notional principal contract, each Holder of a Group I Certificate (other than the Class I-P, Class I-C, Class R-X, and Class I-R Certificates) shall be treated as having agreed to pay, on each Distribution Date, to the Holder of the Class I-C Certificates an aggregate amount equal to the excess, if any, of (i) the amount payable on such Distribution Date on the REMIC regular interest corresponding to such Class of Certificates over (ii) the amount payable on such Class of Certificates on such Distribution Date (such excess, a “Class I Distribution Amount”). A Class I Distribution Amount payable from interest collections shall be allocated pro rata among such Certificates based on the excess of (a) the amount of interest otherwise payable to such Certificates over (ii) the amount of interest payable to such Certificates at a per annum rate equal to the Net WAC Rate, and a Class I Distribution Amount payable from principal collections shall be allocated to the most subordinate Class of Group I Certificates with an outstanding principal balance to the extent of such balance. In addition, pursuant to such notional principal contract, the Holder of the Class I-C Certificates shall be treated as having agreed to pay Net WAC Rate Carryover Amounts to the Holders of the Group I Certificates (other than the Class I-C, Class I-P, Class R-X, and Class I-R Certificates) in accordance with the terms of this Agreement. Any payments to the Group I Certificates from amounts deemed received in respect of this notional principal contract shall not be payments with respect to a regular interest in a REMIC within the meaning of Section 860G(a)(1) of the Code. However, any payment from the Group I Certificates (other than the Class I-C, Class I-P and Class I-R Certificates) of a Class I Distribution Amount shall be treated for federal income tax purposes as having been received by the Holders of such Certificates in respect of their interests in Master REMIC I and as having been paid by such Holders to the Group I Swap Provider pursuant to the notional principal contract. Thus, each Group I Certificate (other than the Class I-P, Class R-X, and Class I-R Certificates) shall be treated as representing not only ownership of regular interests in Master REMIC I, but also ownership of an interest in, and obligations with respect to, a notional principal contract. For federal income tax purposes, the Trust Administrator shall treat such notional principal contract as having a value of $10,000 as of the Closing Date.

In order to enable the Master Servicer to perform its duties as set forth herein, the Depositor shall provide, or cause to be provided, to the Master Servicer within ten (10) days after the Closing Date all information or data that the Master Servicer requests in writing and determines to be relevant for tax purposes to the valuations and offering prices of the Certificates, including, without limitation, the price, yield, prepayment assumption and projected cash flows of the Certificates and the Mortgage Loans. Thereafter, the Depositor shall provide to the Master Servicer promptly upon written request therefor, any such additional information or data that the Master Servicer may, from time to time, reasonably request in order to enable the Master Servicer to perform its duties as set forth herein. The Depositor hereby indemnifies the Master Servicer for any losses, liabilities, damages, claims or expenses of the Master Servicer arising from any errors or miscalculations of the Master Servicer that result from any failure of the Depositor to provide, or to cause to be provided, accurate information or data to the Master Servicer on a timely basis.

In the event that any tax is imposed on “prohibited transactions” of any REMIC as defined in Section 860F(a)(2) of the Code, on the “net income from foreclosure property” of such REMIC as defined in Section 860G(c) of the Code, on any contribution to such REMIC after the Startup Day pursuant to Section 860G(d) of the Code, or any other tax is imposed, if not paid as otherwise provided for herein, such tax shall be paid by (i) the Master Servicer, the Trustee or the Trust Administrator, respectively, if any such other tax arises out of or results from a breach by the Master Servicer, the Trustee or the Trust Administrator, respectively, of any of its obligations under this Agreement, (ii) the Transferor, if any such tax arises out of or results from the Transferor’s obligation to repurchase a Mortgage Loan pursuant to Section 2.02 or 2.03 or (iii) in all other cases, or in the event that the Trustee, the Trust Administrator, the Master Servicer or the Transferor fails to honor its obligations under the preceding clause (i), (ii) or (iii), any such tax will be paid with amounts otherwise to be distributed to the Certificateholders, as provided in Section 3.10(b).

Section 10.12. Periodic Filing.

The Master Servicer shall reasonably cooperate with the Depositor to enable the Trust to satisfy its reporting requirements under the Exchange Act.

The Trust Administrator shall file each Form 10-D with a copy of the related Distribution Date Statement attached thereto. Any disclosure in addition to the Distribution Date Statement that is required to be included on Form 10-D (“Additional Form 10-D Disclosure”) shall be reported by the parties set forth on Exhibit T hereto to the Depositor and the Trust Administrator and be directed and approved by and at the direction of the Depositor pursuant to the following paragraph, and the Trust Administrator will have no duty or liability for any failure hereunder to determine or prepare any Additional Form 10-D Disclosure, except to the extent of its obligations set forth in the next paragraph.

(ii)

For so long as the Trust is subject to the Exchange Act reporting requirements, within 5 calendar days after the related Distribution Date, (i) certain parties set forth on Exhibit T shall be required to provide to the Trust Administrator and the Depositor, to the extent known by a responsible officer thereof, in XXXXX-compatible format, or in such other format as agreed upon by the Trust Administrator and such party, the form and substance of any Additional Form 10-D Disclosure, if applicable, together with an Additional Disclosure Notification and (ii) the Depositor will approve, as to form and substance, or disapprove, as the case may be, the inclusion of the Additional Form 10-D Disclosure on Form 10-X. Xxxxx Fargo, in its capacity as the Trust Administrator only, has no duty under this Agreement to monitor or enforce the performance by the parties listed on Exhibit T of their duties under this paragraph or proactively solicit or procure from such parties any Additional Form 10-D Disclosure information. The Depositor will be responsible for any reasonable fees and expenses assessed or incurred by the Trust Administrator in connection with including any Additional Form 10-D Disclosure on Form 10-D pursuant to this paragraph.

(iii)

After preparing the Form 10-D, the Trust Administrator shall use reasonable best efforts to forward electronically a copy of the Form 10-D to the Depositor and the Master Servicer for review no later than 10 calendar days after the related Distribution Date; provided, the Trust Administrator shall only be required to forward such Form 10-D to the Depositor, where such Form 10-D contains Additional Form 10-D Disclosure. No later than the 12^th calendar day after the Distribution Date, the Depositor shall notify the Trust Administrator in writing (which may be furnished electronically) of any changes to or approval of such Form 10-D. In the absence of receipt of any written changes or approval, the Trust Administrator shall be entitled to assume that such Form 10-D is in final form and the Trust Administrator may proceed with the process for execution and filing of the Form 10-D. A duly authorized representative of the Master Servicer shall sign each Form 10-D. If a Form 10-D cannot be filed on time or if a previously filed Form 10-D needs to be amended, the Trust Administrator will follow the procedures set forth in Section 10.12(d)(ii). Promptly (but no later than one Business Day) after filing with the Commission, the Trust Administrator will make available on its internet website a final executed copy of each Form 10-D filed by the Trust Administrator. Each party to this Agreement acknowledges that the performance by the Trust Administrator of its duties under this Section 10.12 related to the timely preparation, execution and filing of Form 10-D is contingent upon such parties strictly observing all applicable deadlines in the performance of their duties under this Section 10.12. The Depositor acknowledges that the timely performance by the Master Servicer and the Trust Administrator of its duties under this Section 10.12(a) related to the timely preparation, execution and filing of Form 10-D is also contingent upon the Servicers, the Custodian and any Servicing Function Participant strictly observing deadlines no later than those set forth in this paragraph that are applicable to the parties to this Agreement in the delivery to the Trust Administrator of any necessary Additional Form 10-D Disclosure pursuant to the related Servicing Agreements, the Custodial Agreement or any other applicable agreement. Neither the Master Servicer nor the Trust Administrator shall have any liability for any loss, expense, damage or claim arising out of or with respect to any failure to properly prepare, execute and/or timely file such Form 10-D, where such failure results from the Trust Administrator’s inability or failure to obtain or receive, on a timely basis, any information from any other party hereto or any Servicer, Custodian or Servicing Function Participant needed to prepare, arrange for execution or file such Form 10-D, not resulting from its own negligence, bad faith or willful misconduct.

(iv)

Form 10-D requires the registrant to indicate (by checking "yes" or "no") that it "(1) has filed all reports required to be filed by Section 13 or 15(d) of the Exchange Act during the preceding 12 months (or for such shorter period that the registrant was required to file such reports), and (2) has been subject to such filing requirements for the past 90 days." The Depositor hereby instructs the Trust Administrator, with respect to each Form 10-D, to check "yes" for each item unless the Trust Administrator has received timely prior written notice from the Depositor that the answer should be "no" for an item.

(b)

(i)

The Depositor shall use reasonable best efforts to notify the Trust Administrator in writing (which may be furnished electronically) of any changes to or approval of such Form 10-K no later than March 25^th of the related year. In the absence of receipt of any written changes or approval, the Trust Administrator shall be entitled to assume that such Form 10-K is in final form and the Trust Administrator may proceed with the process for execution and filing of the Form 10-K.

If a Form 10-K cannot be filed on time or if a previously filed Form 10-K needs to be amended, the Trust Administrator will follow the procedures set forth in Section 10.12(d)(ii). Form 10-K requires the registrant to indicate (by checking “yes” or “no”) that it “(1) has filed all reports required to be filed by Section 13 or 15(d) of the Exchange Act during the preceding 12 months (or for such shorter period that the registrant was required to file such reports), and (2) has been subject to such filing requirements for the past 90 days.” The Depositor hereby represents to the Trust Administrator that the Depositor has filed all such required reports during the preceding 12 months and that has been subject to such filing requirement for the past 90 days. The Depositor shall notify the Trust Administrator in writing, no later than March 15th with respect to the filing of a report on Form 10-K, if the answer to either question should be “no.” The Trust Administrator shall be entitled to rely on such representations in preparing, executing and/or filing any such report. Promptly (but no later than 1 Business Day) after filing with the Commission, the Trust Administrator will make available on its internet website a final executed copy of each Form 10-K filed by the Trust Administrator. The parties to this Agreement acknowledge that the performance by each of the Master Servicer and Trust Administrator of its duties under this Section 10.12(b) related to the timely preparation, execution and filing of Form 10-K is contingent upon such parties strictly observing all applicable deadlines in the performance of their duties under this Section 10.12(b), Section 3.21, Section 3.22(a) and Section 3.22(b). The Depositor acknowledges that the timely performance by the Master Servicer and the Trust Administrator of its duties under this Section 10.12(b) related to the timely preparation, execution and filing of Form 10-K is also contingent upon the Servicers, the Custodian and any Servicing Function Participant strictly observing deadlines no later than those set forth in this paragraph that are applicable to the parties to this Agreement in the delivery to the Trust Administrator of any necessary Additional Form 10-K Disclosure, any annual statement of compliance and any assessment of compliance and attestation pursuant to the related Servicing Agreement or any other applicable agreement. Neither the Master Servicer nor the Trust Administrator shall have any liability for any loss, expense, damage or claim arising out of or with respect to any failure to properly prepare, execute and/or timely file such Form 10-K, where such failure results from the Trust Administrator’s inability or failure to obtain or receive, on a timely basis, any information from any other party hereto needed to prepare, arrange for execution or file such Form 10-K, not resulting from its own negligence, bad faith or willful misconduct.

(iv)

Each Form 10-K shall include the “Xxxxxxxx-Xxxxx Certification”, exactly as set forth in Exhibit N attached hereto, required to be included therewith pursuant to the Xxxxxxxx-Xxxxx Act. The Depositor, the Master Service and the Trust Administrator shall provide, and each such party shall cause any Servicing Function Participant engaged by it to provide, to the Person who signs the Xxxxxxxx-Xxxxx Certification (the “Certifying Person”), by March 10 (with a 5 calendar day cure period) of each year in which the Trust is subject to the reporting requirements of the Exchange Act and otherwise within a reasonable period of time upon request, a certification (each, a “Back-Up Certification”), in the form attached hereto as Exhibit U, upon which the Certifying Person, the entity for which the Certifying Person acts as an officer, and such entity’s officers, directors and Affiliates (collectively with the Certifying Person, “Certification Parties”) can reasonably rely.

Such officer of the Certifying Person can be contacted by e-mail at xxx.xxx.xxxxxxxxxxxxx@xxxxxxxxxx.xxx or by facsimile at 000-000-0000. In the event any such party or any Servicing Function Participant engaged by the parties is terminated or resigns pursuant to the terms of this Agreement, or any other applicable agreement, as the case may be, such party shall provide a Back-Up Certification to the Certifying Person pursuant to this Section 10.12(b)(iv) with respect to the period of time it was subject to this Agreement or any applicable sub-servicing agreement, as the case may be.

Notwithstanding the foregoing, (i) the Master Servicer and the Trust Administrator shall not be required to deliver a Back-Up Certification to each other if both are the same Person and the Master Servicer is the Certifying Person and (ii) the Master Servicer shall not be obligated to sign the Xxxxxxxx-Xxxxx Certification in the event that it does not receive any Back-Up Certification required to be furnished to it pursuant to this section or any Servicing Agreement.

(a)

Subject to Section 11.02, the respective obligations and responsibilities under this Agreement of the Depositor, the Master Servicer, the Transferor, the Trustee and the Trust Administrator (other than the indemnification obligations of the Master Servicer pursuant to Section 7.03 and the obligation of the Master Servicer to make remittances to the Trust Administrator and of the Trust Administrator to make payments in respect of the Classes of Group I Certificates and to the Group I Certificate Insurer as hereinafter set forth) with respect to the portion of the Trust Fund related to Loan Group I shall terminate upon payment to the Group I Certificateholders and the Group I Certificate Insurer of all amounts required to be distributed to them and the deposit of all amounts held by or on behalf of the Trust Administrator and required hereunder to be so paid or deposited on the Distribution Date coinciding with or following the earlier to occur of (i) the purchase by the Auction Purchaser (as defined below) or the Master Servicer on a servicing retained basis of all Group I Mortgage Loans and each Group I REO Property remaining in REMIC IA (the “Group I Trust Collateral”) and (ii) the final payment or other liquidation (or any advance with respect thereto) of the last Group I Mortgage Loan or Group I REO Property remaining in REMIC IA; provided, however, that in no event shall the trust created hereby continue beyond the earlier of (a) the expiration of 21 years from the death of the last survivor of the descendants of Xxxxxx X. Xxxxxxx, the late ambassador of the United States to the Court of St. Xxxxx, living on the date hereof or (b) the Latest Possible Maturity Date as defined in the Preliminary Statement.

(b)

On any Distribution Date on which the latest of each of the following has occurred: (i) the aggregate Principal Balance of the Group I MTA Loans and each related Group I REO Property remaining in the Trust Fund on such date, after giving effect to distributions to be made on that Distribution Date, is less than 10% of the aggregate Principal Balance of such loans as of the Cut-Off Date, (ii) the aggregate Principal Balance of the Group I LIBOR Loans that have prepayment penalties, and each related Group I REO Property remaining in the Trust Fund on such date, after giving effect to distributions to be made on that Distribution Date, is less than 10% of the aggregate Principal Balance of such loans as of the Cut-Off Date and (iii) the aggregate Principal Balance of the Group I LIBOR Loans that do not have prepayment penalties, and each related Group I REO Property remaining in the Trust Fund on such date, after giving effect to distributions to be made on that Distribution Date, is less than 10% of the aggregate Principal Balance of such loans as of the Cut-Off Date (any such date, an “Auction Date”), the Auction Initiator may direct the Trust Administrator to solicit bids for the Group I Trust Collateral from at least three entities, at least two of which are regular purchasers and/or sellers in the secondary market of residential whole mortgage loans similar to the Group I Mortgage Loans. If the Trust Administrator receives at least three bids for the Group I Trust Collateral, and one of such bids is equal to or greater than the Principal Balance of the Group I Mortgage Loans and the appraised value of any Group I REO Properties, such appraisal to be conducted by an Independent appraiser mutually agreed upon by the Master Servicer, the Group I Certificate Insurer and the Trust Administrator in their reasonable discretion, plus accrued and unpaid interest thereon at the weighted average of the Mortgage Rates through the end of the Due Period preceding the final Distribution Date, plus Servicing Advances, any unpaid Servicing Fees allocable to such Group I Mortgage Loans and Group I REO Properties, any accrued and unpaid Net Rate Carryover then remaining unpaid or which is due to the exercise of such option (collectively, the “Par Value”), the Trust Administrator shall sell the Group I Trust Collateral to the highest bidder (the “Auction Purchaser”) at the price offered by the Auction Purchaser (the “Auction Sale Price”); provided, however, such Auction Sale may only occur (i) if the Auction Sale Price is sufficient to pay (A) all interest accrued on, as well as amounts necessary to retire the principal balance of, each class of notes issued pursuant to the Indenture and any remaining amounts owed to the trustee under the Indenture and the NIMS Insurer on the date such notes are retired and (B) any remaining amounts owed to the Group I Certificate Insurer, the Master Servicer and the Trust Administrator, including without limitation the costs incurred by the Trust Administrator in conducting such auction and any previous auction, (ii) if the fair market value of the Group I Mortgage Loans and Group I REO Properties determined as described above is at least equal to the Principal Balance of the Group I Mortgage Loans (after giving effect to scheduled payments of principal due during the related Due Period, to the extent received or advanced, and unscheduled collections of principal received during the related Prepayment Period) and the appraised value of the Group I REO Properties and (iii) with the consent of the Group I Certificate Insurer if a payment would be required under the Group I Certificate Insurance Policy or if amounts due to the Group I Certificate Insurer would remain unreimbursed. If the Trust Administrator receives less than three bids, or does not receive any bid that is equal to or greater than the Par Value, the Auction Initiator may direct the Trust Administrator, on each six-month anniversary of the initial Auction Date on which the Group I Mortgage Loans remain outstanding, to repeat these auction procedures until the date on which the Trust Administrator receives a bid that is equal to or greater than the Par Value, and sells the Group I Trust Collateral to the Auction Purchaser at the Auction Sale Price. The Trust Administrator shall give notice to the Rating Agencies and each Servicer that is servicing any of the Group I Mortgage Loans of the sale of the Group I Trust Collateral pursuant to this Section 11.01 (an “Auction Sale”) and of the Auction Date.

(c)

If a Majority in Interest of the Class I-C Certificateholders, as Auction Initiator, has not exercised its rights pursuant to Section 11.01(b) to initiate an auction of the Group I Mortgage Loans on any Auction Date, the Master Servicer shall have the right to purchase the Group I Trust Collateral no later than the Determination Date in the month immediately preceding the month in which occurs the Distribution Date on which the Certificates will be retired; provided, however, that the Master Servicer may elect to purchase the Group I Trust Collateral only if both (A) the aggregate Principal Balance of the Group I MTA Loans and each related Group I REO Property remaining in the Trust Fund on such date is reduced to less than 10% of the aggregate Principal Balance of the Group I MTA Loans as of the Cut-off Date and (B) the aggregate Principal Balance of the Group I LIBOR Loans and each related Group I REO Property remaining in the Trust Fund on such date is reduced to less than 10% of the aggregate Principal Balance of the Group I LIBOR Loans as of the Cut-off Date.

Subject to Section 3.10 hereof, the purchase by the Master Servicer of all Mortgage Loans and each Group I REO Property remaining in REMIC IA shall be at a price (the “Termination Price”) equal to the greater of (i) the Principal Balance of the Group I Mortgage Loans and the appraised value of any Group I REO Properties, such appraisal to be conducted by an Independent appraiser mutually agreed upon by the Master Servicer and the Trust Administrator in their reasonable discretion and (ii) the fair market value of all of the assets of REMIC IA (as determined by the Master Servicer and the Trust Administrator, as of the close of business on the third Business Day next preceding the date upon which notice of any such termination is furnished to Certificateholders pursuant to Section 11.01(d)) in each case, plus accrued and unpaid interest thereon at the weighted average of the Mortgage Rates through the end of the Due Period preceding the final Distribution Date, plus Servicing Advances, any unpaid Servicing Fees allocable to such Group I Mortgage Loans and Group I REO Properties and any accrued and unpaid Net Rate Carryover; provided, however, such option may only be exercised (i) if the Termination Price is sufficient to pay (A) all interest accrued on, as well as amounts necessary to retire the principal balance of, each class of notes issued pursuant to the Indenture and any remaining amounts owed to the trustee under the Indenture and the NIMS Insurer on the date such notes are retired and (B) any remaining amounts owed to the Group I Certificate Insurer, (ii) if the fair market value of the Group I Mortgage Loans and Group I REO Properties determined as described above is at least equal to the Principal Balance of the Group I Mortgage Loans (after giving effect to scheduled payments of principal due during the related Due Period, to the extent received or advanced, and unscheduled collections of principal received during the related Prepayment Period) and the appraised value of the Group I REO Properties and (iii) with the consent of the Group I Certificate Insurer if a payment would be required under the Group I Certificate Insurance Policy or if amounts due to the Group I Certificate Insurer would remain unreimbursed.

By acceptance of the Group I Residual Certificates, the Holder of the Group I Residual Certificates agrees for so long as any notes insured by the NIMS Insurer and secured by all or a portion of the Class I-C, Class I-P or Class I-R Certificates are outstanding, in connection with any termination hereunder, to assign and transfer any amounts in excess of par, and to the extent received in respect of such termination, to pay any such amounts to the Holders of the Class I-C Certificates.

(d)

Notice of the liquidation of the Group I Certificates shall be given promptly by the Trust Administrator by letter to the Group I Certificateholders, the Group I Certificate Insurer, the NIMS Insurer and the Trustee mailed (a) in the event such notice is given in connection with the purchase of the Group I Mortgage Loans and each Group I REO Property by the Master Servicer, not earlier than the 10th day and not later than the 20th day of the month next preceding the month of the final distribution on the Certificates or (b) otherwise during the month of such final distribution on or before the Determination Date in such month, in each case specifying (i) the Distribution Date upon which the portion of the Trust Fund related to Loan Group I will terminate and the final payment in respect of the Group I Certificates will be made upon presentation and surrender of the related Group I Certificates at the office of the Trust Administrator therein designated, (ii) the amount of any such final payment, (iii) that no interest shall accrue in respect of the REMIC IA Regular Interests or the Group I Certificates from and after the Accrual Period relating to the final Distribution Date therefor and (iv) that the Record Date otherwise applicable to such Distribution Date is not applicable, payments being made only upon presentation and surrender of the Group I Certificates at the office of the Trust Administrator.

In the event such notice is given in connection with the purchase of all of the Group I Mortgage Loans and each Group I REO Property remaining in REMIC IA by the Master Servicer, the Master Servicer shall deliver to the Trust Administrator for deposit in the Distribution Account not later than the last Business Day of the month next preceding the month of the final distribution on the Group I Certificates an amount in immediately available funds equal to the Termination Price. The Trust Administrator shall remit to the Master Servicer from such funds deposited in the Distribution Account (i) any amounts which the Master Servicer would be permitted to withdraw and retain from the Collection Account pursuant to Section 3.10 and (ii) any other amounts otherwise payable by the Trust Administrator to the Master Servicer from amounts on deposit in the Distribution Account pursuant to the terms of this Agreement, in each case prior to making any final distributions pursuant to Section 4.02. Upon certification to the Trust Administrator by the Master Servicer of the making of such final deposit and of the delivery of the Group I Certificate Insurance Policy to the Group I Certificate Insurer for cancellation, the Trustee (or the Custodian on its behalf) shall promptly release to the Master Servicer the Mortgage Files for the remaining Group I Mortgage Loans, and the Trustee (or, as applicable, the Custodian on its behalf) shall execute all assignments, endorsements and other instruments necessary to effectuate such transfer.

In the event such notice is given in connection with the purchase of the Group I Trust Collateral by the Auction Purchaser, the Auction Purchaser shall deliver to the Trust Administrator for deposit in the Distribution Account not later than the last Business Day of the month next preceding the month of the final distribution on the Group I Certificates an amount in immediately available funds equal to the Auction Sale Price. Upon the making of such final deposit and certification to the Trust Administrator by the Auction Purchaser of the delivery of the Group I Certificate Insurance Policy to the Group I Certificate Insurer for cancellation, the Trust Administrator shall promptly release to the Auction Purchaser the Mortgage Files for the remaining Group I Mortgage Loans, and the Trust Administrator shall execute all assignments, endorsements and other instruments necessary to effectuate such transfer.

(e)

Upon presentation of the Group I Certificates by the Certificateholders on the final Distribution Date, the Trust Administrator shall distribute to each Group I Certificateholder so presenting and surrendering its Group I Certificates the amount otherwise distributable on such Distribution Date in accordance with Section 4.02 in respect of the Group I Certificates so presented and surrendered. Any funds not distributed to any Holder or Holders of Group I Certificates being retired on such Distribution Date because of the failure of such Holder or Holders to tender their Group I Certificates shall, on such date, be set aside and held in trust and credited to the account of the appropriate non-tendering Holder or Holders. If any Group I Certificates as to which notice has been given pursuant to this Section 11.01 shall not have been surrendered for cancellation within six months after the time specified in such notice, the Trust Administrator shall mail a second notice to the remaining non-tendering Group I Certificateholders to surrender their Group I Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Group I Certificates shall not have been surrendered for cancellation, the Trust Administrator shall, directly or through an agent, mail a final notice to the remaining non-tendering Group I Certificateholders concerning surrender of their Group I Certificates. The costs and expenses of maintaining the funds in trust and of contacting such Group I Certificateholders shall be paid out of the assets remaining in the Trust Fund. If within one year after the final notice any such Group I Certificates shall not have been surrendered for cancellation, the Trust Administrator shall pay to UBS Securities LLC, all such amounts, and all rights of non-tendering Group I Certificateholders in or to such amounts shall thereupon cease hereunder, under the related Group I Certificates and, if applicable, under the Group I Certificate Insurance Policy. No interest shall accrue or be payable to any Group I Certificateholder on any amount held in trust by the Trust Administrator as a result of such Group I Certificateholder’s failure to surrender its Group I Certificate(s) for final payment thereof in accordance with this Section 11.01. Any such amounts held in trust by the Trust Administrator shall be held in an Eligible Account and the Trust Administrator may direct any depository institution maintaining such account to invest the funds in one or more Permitted Investments. All income and gain realized from the investment of funds deposited in such accounts held in trust by the Trust Administrator shall be for the benefit of the Trust Administrator; provided, however, that the Trust Administrator shall deposit in such account the amount of any loss of principal incurred in respect of any such Permitted Investment made with funds in such accounts immediately upon the realization of such loss.

Immediately following the deposit of funds in trust hereunder in respect of the Group I Certificates, the portion of the Trust Fund related to Loan Group II shall terminate.

With respect to the Group II Mortgage Loans to be purchased, if fewer than three bids are received or no cash bid exceeds the aggregate of the Par Call Price for the Group II Mortgage Loans, the Fair Market Value Call Price shall be zero and the Master Servicer shall complete the purchase of the Group II Mortgage Loans and the Group II REO Properties from the Trust Fund at the aggregate Clean-up Call Mortgage Loan Price for the Group II Mortgage Loans and the aggregate Clean-up Call Group II REO Property Price for the Group II REO Properties before the final Distribution Date for the related Group II Certificates.

Section 11.04. Final Distribution on the Group II Certificates.

If on any Determination Date, the Master Servicer determines that there are no Outstanding Group II Mortgage Loans and no other funds or assets in the Trust Fund related to Loan Group II other than the funds in the Collection Account, the Master Servicer shall direct the Trust Administrator promptly to send a Notice of Final Distribution to each Group II Certificateholder. If the Master Servicer elects to terminate the portion of the Trust Fund related to Loan Group II pursuant to clause (a) of Section 11.03, by purchasing certain Group II Mortgage Loans and Group II REO Properties by no later than the 10th day of the month of the expected final distribution, the Master Servicer shall notify the Depositor and the Trust Administrator of the Distribution Date on which the Master Servicer intends to terminate such portion of the Trust Fund; provided, however, if the Trust Administrator and the Master Servicer are not the same Person, then such notice shall occur by no later than the 7^th day of the month of the expected final distribution for the related Group II Certificates.

Notice of any termination of the portion of the Trust Fund related to Loan Group II, specifying the Distribution Date on which the related Group II Certificateholders may surrender their Group II Certificates for payment of the final distribution and cancellation, shall be given promptly by the Trust Administrator by letter to the related Group II Certificateholders mailed not later than the 10th day of the month of such final distribution. Any such Notice of Final Distribution shall specify (a) the Distribution Date upon which final distribution on the related Group II Certificates will be made upon presentation and surrender of Group II Certificates at the office therein designated, (b) the location of the office or agency at which such presentation and surrender must be made, and (c) that the Record Date otherwise applicable to such Distribution Date is not applicable, distributions being made only upon presentation and surrender of the related Certificates at the office therein specified. The Trust Administrator will give such notice to each Rating Agency at the time such notice is given to Group II Certificateholders. In connection with any such termination of a portion of the Trust Fund, the Master Servicer shall cause all funds in the Collection Account, including the Clean-up Call Mortgage Loan Price and Clean-up Call Group II REO Property Price for the related Group II Mortgage Loans and Group II REO Properties, respectively, to be remitted to the Trust Administrator for deposit in the Distribution Account no later than the Business Day prior to the applicable Distribution Date. Upon such final deposit by the Master Servicer with respect to the Trust Fund and the receipt by the Trust Administrator of a Request for Release therefor, the Trust Administrator shall promptly release to the Master Servicer, or its designee, the Mortgage Files for the related Group II Mortgage Loans.

Upon presentation and surrender of the Group II Certificates, the Trust Administrator shall cause to be distributed to the Group II Certificateholders of each Class, in the order set forth in Section 5.02 hereof, on the final Distribution Date for the related Group II Certificates, in proportion to their respective Percentage Interests, with respect to Group II Certificateholders of the same Class, an amount equal to (i) as to each related Class of Group II Certificates that are Regular Certificates, the Certificate Principal Balance thereof plus accrued interest thereon and (ii) as to the Group II Residual Certificates, the amount, if any, that remains on deposit in the Distribution Account related to Loan Group II (other than the amounts retained to meet claims).

In the event that any affected Group II Certificateholders shall not surrender Group II Certificates for cancellation within six months after the date specified in the above mentioned written notice, the Trust Administrator shall give a second written notice to the remaining Group II Certificateholders to surrender their Group II Certificates for cancellation and receive the final distribution with respect thereto. If within six months after the second notice all the applicable Group II Certificates shall not have been surrendered for cancellation, the Trust Administrator may take reasonable steps, or may appoint an agent to take reasonable steps, to contact the remaining Group II Certificateholders concerning surrender of their Group II Certificates, and the cost thereof shall be paid out of the funds and other assets of the Master REMIC II that remain subject hereto and (i) the Class II-A-LR Certificateholders shall be entitled to all unclaimed funds and other assets of REMIC IB and (ii) the Class A-R Certificateholders shall be entitled to all unclaimed funds and other assets of Master REMIC II, in each case, that remain subject hereto.

Section 11.05. Additional Termination Requirements.

In the event the purchase option described in clause (a) of Section 11.03 is exercised, each REMIC related to Loan Group II created hereby shall be terminated in accordance with the following additional requirements, unless each of the Trust Administrator and the Trustee has been supplied with an Opinion of Counsel, at the expense of the Master Servicer, to the effect that the failure to comply with the requirements of this Section 11.03 will not (i) result in the imposition of taxes on “prohibited transactions” on any REMIC created hereby as defined in Section 860F of the Code, or (ii) cause any such REMIC to fail to qualify as a REMIC at any time that any Group II Certificates are outstanding:

(i)

The notice given by the Master Servicer under Section 11.02 shall provide that such notice constitutes the adoption of a plan of complete liquidation of the related REMICs as of the date of such notice (or, if earlier, the date on which the first such notice is mailed to Certificateholders). The Master Servicer shall also specify such date in a statement attached to the final tax return of each such REMIC; and

(ii)

Within 89 days of adoption of such a plan of complete liquidation of such REMICs and at or prior to the final Distribution Date, the Trust Administrator shall sell all of the assets of the Trust Fund related to the Group II Mortgage Loans to the Master Servicer for cash at the purchase price specified in Section 11.01 and shall distribute such cash by the next Distribution Date after such adoption in the manner specified in Section 11.02.

The Trust Administrator, the Trustee, the Depositor, the Transferor, the Custodian and the Master Servicer also may at any time and from time to time amend this Agreement with the consent of the NIMS Insurer and the Group I Certificate Insurer and without the consent of the Certificateholders to modify, eliminate or add to any of its provisions to such extent as shall be necessary or helpful to (i) maintain the qualification of any REMIC created under this Agreement as a REMIC under the Code, (ii) avoid or minimize the risk of the imposition of any tax on any REMIC pursuant to the Code that would be a claim at any time prior to the final redemption of the Certificates or (iii) comply with any other requirements of the Code, provided that the Trust Administrator, the NIMS Insurer, the Group I Certificate Insurer and the Master Servicer have been provided an Opinion of Counsel addressed to the Trust Administrator, the NIMS Insurer, the Group I Certificate Insurer and the Master Servicer, which opinion shall be an expense of the party requesting such opinion but in any case shall not be an expense of the Trustee, the Trust Administrator, the Master Servicer or the Trust Fund, to the effect that such action is necessary or helpful to, as applicable, (i) maintain such qualification, (ii) avoid or minimize the risk of the imposition of such a tax or (iii) comply with any such requirements of the Code. In addition, this Agreement may be amended from time to time by the Depositor, the Master Servicer, the Trust Administrator, the Transferor and the Trustee without the consent of any of the Certificateholders to comply with the provisions of Regulation AB.

Section 10.12 of this Agreement may also be amended by the Depositor, the Transferor, the Master Servicer, the Trust Administrator and the Trustee with the consent of the NIMS Insurer and the Group I Certificate Insurer and without the consent of any of the Certificateholders, and without the need for any Opinions of Counsel or Rating Agency confirmation, in the event that new guidelines or procedures are issued by the Securities and Exchange Commission with respect to the preparation and filing of the Form 10-K and the Certification required to be attached thereto as referenced in Section 10.12(d).

This Agreement may also be amended from time to time by the Depositor, the Transferor, the Master Servicer, the Custodian, the Trust Administrator and the Trustee with the consent of the NIMS Insurer, the Group I Certificate Insurer, and the Holders of a Majority in Interest of each Class of Certificates affected thereby for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Agreement or of modifying in any manner the rights of the Holders of Certificates; provided, however, that no such amendment shall (i) reduce in any manner the amount of, or delay the timing of, payments required to be distributed on any Certificate without the consent of the Holder of such Certificate, (ii) adversely affect in any material respect the interests of the Holders of any Class of Certificates in a manner other than as described in the preceding clause (i), without the consent of the Holders of Certificates of such Class evidencing, as to such Class, Percentage Interests aggregating 66% or (iii) reduce the aforesaid percentages of Certificates the Holders of which are required to consent to any such amendment, without the consent of the Holders of all such Certificates then outstanding.

Notwithstanding any contrary provision of this Agreement, the Trustee, the NIMS Insurer and the Trust Administrator shall not consent to any amendment to this Agreement (other than pursuant to the second preceding paragraph) unless it shall have first received an Opinion of Counsel addressed to the Trustee, the NIMS Insurer, the Group I Certificate Insurer and the Trust Administrator, which opinion shall not be an expense of the Trustee, the Trust Administrator or the Trust Fund, to the effect that such amendment is permitted hereunder and will not cause the imposition of any tax under the REMIC Provisions on any REMIC or the Certificateholders or cause any REMIC created under this Agreement to fail to qualify as a REMIC at any time that any Certificates are outstanding.

Promptly after the execution of any amendment to this Agreement requiring the consent of Certificateholders, the Trust Administrator shall furnish written notification of the substance or a copy of such amendment to each Certificateholder, the Group I Certificate Insurer, the NIMS Insurer and each Rating Agency.

It shall not be necessary for the consent of Certificateholders under this Section to approve the particular form of any proposed amendment, but it shall be sufficient if such consent shall approve the substance thereof. The manner of obtaining such consents and of evidencing the authorization of the execution thereof by Certificateholders shall be subject to such reasonable regulations as the Trust Administrator may prescribe.

Nothing in this Agreement shall require the Trustee or the Trust Administrator to enter into an amendment without receiving an Opinion of Counsel addressed to the Trust Administrator, the Group I Certificate Insurer and the Trustee (which Opinion shall not be an expense of the Trustee, the Trust Administrator or the Trust Fund), satisfactory to the Trust Administrator and the Group I Certificate Insurer that (i) such amendment is permitted and is not prohibited by this Agreement and that all requirements for amending this Agreement have been complied with; and (ii) either (A) the amendment does not adversely affect in any material respect the interests of any Certificateholder or the Group I Certificate Insurer or (B) the conclusion set forth in the immediately preceding clause (A) is not required to be reached pursuant to this Section 12.01. Notwithstanding anything to the contrary in this Section 12.01, the Trustee, the Custodian, the Trust Administrator and the Master Servicer shall reasonably cooperate with the Depositor and its counsel to enter into such amendments or modifications to the Agreement as may be necessary to comply with Regulation AB and any interpretation thereof by the Commission.

Section 12.02. Recordation of Agreement; Counterparts.

This Agreement (or an abstract hereof, if acceptable to the applicable recording office) is subject to recordation in all appropriate public offices for real property records in all the towns or other comparable jurisdictions in which any or all of the Mortgaged Properties are situated, and in any other appropriate public office or elsewhere, such recordation to be effected by the Master Servicer at the expense of the Trust on direction by the Trust Administrator (acting at the written direction of a Majority in Interest of the Certificateholders), but only upon direction accompanied by an Opinion of Counsel to the effect that such recordation materially and beneficially affects the interests of the Certificateholders.

For the purpose of facilitating the recordation of this Agreement as herein provided and for other purposes, this Agreement may be executed simultaneously in any number of counterparts, each of which counterparts shall be deemed to be an original, and such counterparts shall constitute but one and the same instrument.

Section 12.03. Governing Law.

THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE SUBSTANTIVE LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED IN THE STATE OF NEW YORK AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HERETO AND THE CERTIFICATEHOLDERS SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.

Section 12.04. Intention of Parties.

It is the express intent of the parties hereto that the conveyance of the Trust Fund by the Depositor to the Trustee be, and be construed as, an absolute sale thereof to the Trustee. It is, further, not the intention of the parties that such conveyance be deemed a pledge thereof by the Depositor to the Trustee. However, in the event that, notwithstanding the intent of the parties, such assets are held to be the property of the Depositor, or if for any other reason this Agreement is held or deemed to create a security interest in such assets, then (i) this Agreement shall be deemed to be a security agreement within the meaning of the Uniform Commercial Code of the State of New York and (ii) the conveyance provided for in this Agreement shall be deemed to be an assignment and a grant by the Depositor to the Trustee, for the benefit of the Certificateholders and the Group I Certificate Insurer, of a security interest in all of the assets that constitute the Trust Fund, whether now owned or hereafter acquired.

The Depositor for the benefit of the Certificateholders and the Group I Certificate Insurer shall, to the extent consistent with this Agreement, take such actions as may be necessary to ensure that, if this Agreement were deemed to create a security interest in the Trust Fund, such security interest would be deemed to be a perfected security interest of first priority under applicable law and will be maintained as such throughout the term of the Agreement. The Depositor shall arrange for filing any Uniform Commercial Code continuation statements in connection with any security interest granted or assigned to the Trustee for the benefit of the Certificateholders and the Group I Certificate Insurer.

Pursuant to Section 7.05, the Master Servicer shall be permitted to pledge its rights as servicer hereunder to a lender, provided that no such pledge shall permit the termination of the Master Servicer as Master Servicer unless a successor servicer meeting the requirements of Sections 6.04 and 7.02 hereunder shall have assumed the rights and obligations of the Master Servicer hereunder.

Section 12.08. Limitation on Rights of Certificateholders.

The death or incapacity of any Certificateholder shall not operate to terminate this Agreement or the trust created hereby, nor entitle such Certificateholder’s legal representative or heirs to claim an accounting or to take any action or commence any proceeding in any court for a petition or winding up of the trust created hereby, or otherwise affect the rights, obligations and liabilities of the parties hereto or any of them.

No Certificateholder shall have any right to vote (except as provided herein) or in any manner otherwise control the operation and management of the Trust Fund, or the obligations of the parties hereto, nor shall anything herein set forth or contained in the terms of the Certificates be construed so as to constitute the Certificateholders from time to time as partners or members of an association; nor shall any Certificateholder be under any liability to any third party by reason of any action taken by the parties to this Agreement pursuant to any provision hereof.

No Certificateholder shall have any right by virtue or by availing itself of any provisions of this Agreement to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Agreement, unless such Holder previously shall have given to the Trustee or the Trust Administrator a written notice of a Master Servicer Event of Termination and of the continuance thereof, as herein provided, and unless the Holders of Certificates evidencing not less than 25% of the Voting Rights evidenced by the Certificates shall also have made written request to the Trustee or the Trust Administrator to institute such action, suit or proceeding in its own name as Trustee or Trust Administrator hereunder and shall have offered to the Trust Administrator such reasonable indemnity as it may require against the costs, expenses, and liabilities to be incurred therein or thereby, and the Trustee or the Trust Administrator, for 60 days after its receipt of such notice, request and offer of indemnity shall have neglected or refused to institute any such action, suit or proceeding; it being understood and intended, and being expressly covenanted by each Certificateholder with every other Certificateholder and the Trustee or the Trust Administrator, that no one or more Holders of Certificates shall have any right in any manner whatever by virtue or by availing itself or themselves of any provisions of this Agreement to affect, disturb or prejudice the rights of the Holders of any other of the Certificates, or to obtain or seek to obtain priority over or preference to any other such Holder or to enforce any right under this Agreement, except in the manner herein provided and for the common benefit of all Certificateholders. For the protection and enforcement of the provisions of this Section 12.08, each and every Certificateholder and the Trustee and the Trust Administrator shall be entitled to such relief as can be given either at law or in equity.

Section 12.09. Inspection and Audit Rights.

The Master Servicer agrees that, on reasonable prior notice, it will permit and will cause each Servicer to permit any representative of the Depositor or the Trustee during the Master Servicer’s or Servicer’s, as the case may be, normal business hours, to examine all the books of account, records, reports and other papers of the Master Servicer or each Servicer, as the case may be, relating to the Mortgage Loans, to make copies and extracts therefrom, to cause such books to be audited by independent certified public accountants selected by the Depositor or the Trustee and to discuss its affairs, finances and accounts relating to the Mortgage Loans with its officers, employees and independent public accountants (and by this provision the Master Servicer or each Servicer, as the case may be, hereby authorize said accountants to discuss with such representative such affairs, finances and accounts), all at such reasonable times and as often as may be reasonably requested. Any out-of-pocket expense incident to the exercise by the Depositor or the Trustee of any right under this Section 12.09 shall be borne by the party requesting such inspection; all other such expenses shall be borne by the Master Servicer or the related Servicer.

Section 12.10. Certificates Nonassessable and Fully Paid.

It is the intention of the Depositor that Certificateholders shall not be personally liable for obligations of the Trust Fund, that the interests in the Trust Fund represented by the Certificates shall be nonassessable for any reason whatsoever, and that the Certificates, upon due authentication thereof by the Trustee pursuant to this Agreement, are and shall be deemed fully paid.

ARTICLE XIII

CERTAIN MATTERS REGARDING THE GROUP I CERTIFICATE INSURER

Section 13.01. Exercise of Voting Rights of Holder of the Insured Certificates.

For so long as there is no continuing default by the Group I Certificate Insurer in respect of its obligations under the Group I Certificate Insurance Policy (a “Certificate Insurer Default”), each of the Depositor, the Master Servicer, the Trust Administrator and the Trustee, and, by accepting its Insured Certificate, each Holder of an Insured Certificate, agrees that the Group I Certificate Insurer shall have the right to exercise all Voting Rights of the Holders of the Insured Certificates under this Agreement without any further consent of the Holders of the Insured Certificates.

In addition, each Holder of an Insured Certificate agrees that, unless a Certificate Insurer Default has occurred and is continuing, the Voting Rights of such Holder with respect to such Insured Certificate may be exercised by such Holder only with the prior written consent of the Group I Certificate Insurer.

Section 13.02. Trustee and Trust Administrator to Act Solely with Consent of Certificate Insurer.

Unless a Certificate Insurer Default has occurred and is continuing, neither the Trustee nor the Trust Administrator shall undertake any litigation pursuant to Section 9.02(a)(ix) at the request or direction of the Certificateholders, without the prior written consent of the Group I Certificate Insurer (which consent shall not be unreasonably withheld or delayed); provided, however, nothing contained herein shall prohibit or prevent the Trustee and the Trust Administrator from defending itself or the Trust Fund or taking any action related thereto.

Section 13.03. Trust Fund and Accounts Held for Benefit of Certificate Insurer.

The Trustee shall hold the Trust Fund and the Mortgage Files for the benefit of the Certificateholders and the Group I Certificate Insurer and all references in this Agreement (including, without limitation, in Sections 2.01 and 2.02) and in the Certificates to the benefit of Holders of the Certificates shall be deemed to include the Group I Certificate Insurer.

The Master Servicer hereby acknowledges and agrees that it shall master service and administer the related Loans and any Group II REO Properties, and the Trust Administrator hereby acknowledges and agrees that it shall maintain the Distribution Account, for the benefit of the Certificateholders and for the benefit of the Group I Certificate Insurer, and all references in this Agreement (including, without limitation, in Section 3.01) to the benefit of or actions on behalf of the Certificateholders shall be deemed to include the Group I Certificate Insurer. Unless a Certificate Insurer Default has occurred and is continuing, neither the Master Servicer nor the Depositor shall undertake any litigation pursuant to Section 7.03 (other than litigation to enforce their respective rights hereunder or defend themselves against claims made against them) without the prior consent of the Group I Certificate Insurer (which consent shall not be unreasonably withheld or delayed).

Section 13.04. Claims Upon the Group I Certificate Insurance Policy; Policy Payments Account.

(a)

If, at or before 12:00 p.m., New York time, on the second Business Day prior to a Distribution Date, the Trust Administrator determines that the Available Funds for such Distribution Date distributable to the Holders of the Insured Certificates pursuant to Section 5.02 will be insufficient to pay the Guaranteed Distributions (as defined in the Group I Certificate Insurance Policy) for each Class of Insured Certificates on such Distribution Date, the Trust Administrator shall determine the amount of any such deficiency and shall give notice to the Group I Certificate Insurer and the Fiscal Agent (as defined in the Group I Certificate Insurance Policy), if any, by telephone, electronic mail or telecopy of the amount of such deficiency. Such notice of such deficiency shall be confirmed in writing in the form set forth as Exhibit A to the Endorsement to the Group I Certificate Insurance Policy, to the Group I Certificate Insurer at or before 12:00 p.m. New York time on the second Business Day prior to such Distribution Date and will be accompanied by sufficient information such that the Group I Certificate Insurer can confirm the deficiency amount. Following Receipt (as defined in the Group I Certificate Insurance Policy) by the Group I Certificate Insurer of such notice in such form, the Group I Certificate Insurer will pay any amount payable under the Group I Certificate Insurance Policy on the later to occur of (i) 12:00 noon New York time on the second Business Day following such receipt and (ii) 12:00 noon New York time on the Distribution Date to which such claims relates, as provided in the Endorsement to the Group I Certificate Insurance Policy.

(b)

The Trust Administrator is hereby appointed as agent for the Trustee in connection with the receipt and distribution of all amounts required to be paid by the Group I Certificate Insurer under the Group I Certificate Insurance Policy and the providing of any notices required to be provided thereunder. The Trust Administrator on behalf of the Trustee shall establish a segregated non-interest bearing trust account for the benefit of Holders of the Insured Certificates and the Group I Certificate Insurer referred to herein as the “Policy Payments Account” over which the Trust Administrator shall have exclusive control and sole right of withdrawal. The Trust Administrator shall deposit any amount paid under the Group I Certificate Insurance Policy in the Policy Payments Account and distribute such amount only for purposes of payment to Holders of Insured Certificates of the Guaranteed Distributions or any amount in respect of a Preference Claim (as defined in the Group I Certificate Insurance Policy) for which a claim under the Group I Certificate Insurance Policy was made, and such amount may not be applied to satisfy any costs, expenses or liabilities of the Master Servicer, the Trust Administrator, the Trustee or the Trust Fund. Amounts paid under the Group I Certificate Insurance Policy shall be transferred to the Distribution Account in accordance with the next succeeding paragraph and disbursed by the Trust Administrator to Holders of the Insured Certificates entitled to such amounts in accordance with Section 4.02 (or, in the case of an amount in respect of a Preference Claim, to the related Holders of Insured Certificates as contemplated in Section 13.04(d)). It shall not be necessary for such payments to be made by checks or wire transfers separate from the checks or wire transfers used to pay the other distributions to be made to such Holders pursuant to Section 4.02. However, the amount of any payment of principal of or interest on the Insured Certificates to be paid from funds transferred from the Policy Payments Account shall be noted as provided in paragraph (c) below in the Certificate Register and in the statement to be furnished to Holders of the Insured Certificates pursuant to Section 4.04. Funds held in the Policy Payments Account shall not be invested.

(c)

On any Distribution Date with respect to which a claim has been made under the Group I Certificate Insurance Policy, the amount of any funds received by the Trust Administrator on behalf of the Trustee as a result of any claim under the Group I Certificate Insurance Policy, to the extent required to pay the Insured Amount on such Distribution Date, shall be withdrawn from the Policy Payments Account and deposited in the Distribution Account and applied by the Trust Administrator, directly to the payment in full of the Insured Amount due on the Insured Certificates. Funds received by the Trust Administrator on behalf of the Trustee as a result of any claim under the Group I Certificate Insurance Policy shall be deposited by the Trust Administrator in the Policy Payments Account and used solely for payment to the Holders of the Insured Certificates and may not be applied to satisfy any costs, expenses or liabilities of the Master Servicer, the Trust Administrator, the Trustee or the Trust Fund. Any funds remaining in the Policy Payments Account on the first Business Day following a Distribution Date shall be remitted to the Group I Certificate Insurer, pursuant to (and subject to receipt of) the instructions of the Group I Certificate Insurer, by the end of such Business Day.

(d)

The Trust Administrator shall keep complete and accurate records in respect of (i) all funds remitted to it by the Group I Certificate Insurer and (ii) the allocation of such funds to (A) payments of interest on and principal in respect of each Class of Insured Certificates, (B) Realized Losses allocated to each Class of the Insured Certificates and (C) the amount of funds available to make distributions on the Insured Certificates pursuant to Section 4.02. The Group I Certificate Insurer shall have the right to inspect such records at reasonable times during normal business hours upon three Business Days’ prior notice to the Trust Administrator.

Immediately prior to the transfer and assignment contemplated herein, the Transferor was the sole owner and holder of the Mortgage Loan free and clear of any and all liens, pledges, charges or security interests of any nature and has full right and authority to sell and assign the same;

(iii)

The Mortgage is a valid, subsisting and enforceable first lien on the property therein described, and the Mortgaged Property is free and clear of all encumbrances and liens having priority over the first lien of the Mortgage except for liens for real estate taxes and special assessments not yet due and payable and liens or interests arising under or as a result of any federal, state or local law, regulation or ordinance relating to hazardous wastes or hazardous substances, and, if the related Mortgaged Property is a condominium unit, any lien for common charges permitted by statute or homeowners association fees; and if the Mortgaged Property consists of shares of a cooperative housing corporation, any lien for amounts due to the cooperative housing corporation for unpaid assessments or charges or any lien of any assignment of rents or maintenance expenses secured by the real property owned by the cooperative housing corporation; and any security agreement, chattel mortgage or equivalent document related to, and delivered to the Trustee or to the Master Servicer with, any Mortgage establishes in the Transferor a valid and subsisting first lien on the property described therein and the Transferor has full right to sell and assign the same to the Trustee;

(iv)

Neither the Transferor nor any prior holder of the Mortgage or the related Mortgage Note has modified the Mortgage or the related Mortgage Note in any material respect, satisfied, canceled or subordinated the Mortgage in whole or in part, released the Mortgaged Property in whole or in part from the lien of the Mortgage, or executed any instrument of release, cancellation, waiver, modification or satisfaction, except in each case as is reflected in an agreement delivered to the Trustee or the Master Servicer pursuant to Section 2.01;

All taxes, governmental assessments, insurance premiums, and water, sewer and municipal charges, which previously became due and owing have been paid, or an escrow of funds has been established, to the extent permitted by law, in an amount sufficient to pay for every such item that remains unpaid; and the Transferor has not advanced funds, or received any advance of funds by a party other than the Mortgagor, directly or indirectly for the payment of any amount required by the Mortgage, except for interest accruing from the date of the Mortgage Note or date of disbursement of the Mortgage Loan proceeds, whichever is later, to the day which precedes by thirty days the first Due Date under the related Mortgage Note;

(vi)

The Mortgaged Property is undamaged by water, fire, earthquake or other earth movement, windstorm, flood, tornado or similar casualty (excluding casualty from the presence of hazardous wastes or hazardous substances, as to which the Transferor makes no representations), so as to affect adversely the value of the Mortgaged Property as security for the Mortgage Loan or the use for which the premises were intended and to the best of the Transferor’s knowledge, there is no proceeding pending or threatened for the total or partial condemnation of the Mortgaged Property;

(vii)

The Mortgaged Property is free and clear of all mechanics’ and materialmen’s liens or liens in the nature thereof; provided, however, that this warranty shall be deemed not to have been made at the time of the initial issuance of the Certificates if a title policy affording, in substance, the same protection afforded by this warranty is furnished to the Trustee by the Transferor;

(xii)

The Mortgage Note, the related Mortgage and other agreements executed in connection therewith are genuine, and each is the legal, valid and binding obligation of the maker thereof, enforceable in accordance with its terms, except as such enforcement may be limited by bankruptcy, insolvency, reorganization or other similar laws affecting the enforcement of creditors’ rights generally and by general equity principles (regardless of whether such enforcement is considered in a proceeding in equity or at law); and, to the best of the Transferor’s knowledge, all parties to the Mortgage Note and the Mortgage had legal capacity to execute the Mortgage Note and the Mortgage and each Mortgage Note and Mortgage has been duly and properly executed by the Mortgagor;

No Subgroup I-1 Mortgage Loan is a “high cost home,” “covered” (excluding home loans defined as "covered home loans" in the New Jersey Home Ownership Security Act of 2002 that were originated between November 26, 2003 and July 7, 2004), “high risk home” or “predatory” loan under any applicable state, federal or local 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).

(xlii)

The original principal balance of each Group 1 Mortgage Loan is within Xxxxxxx Mac's dollar amount limits for conforming mortgage loans.

(xliii)

No Subgroup I-1 Mortgage Loan that is a refinance or purchase money mortgage loan, if any, has an APR or total points and fees that exceed the thresholds set by the Home Ownership and Equity Protection Act of 1994 (“HOEPA”) and its implementing regulations, including 12 CFR § 226.32(a)(1)(i) and (ii).

(xliv)

No Subgroup I-1 Mortgage Loan was originated on or after January 1, 2005, which is a “high cost home loan” as defined under the Indiana Home Loan Practices Act (I.C. 24-9);

(xlv)

With respect to each Subgroup I-1 Mortgage Loan, the borrower was not encouraged or required to select a mortgage loan product offered by the Mortgage Loan’s originator which is a higher cost product designed for less creditworthy borrowers, taking into account such facts as, without limitation, the Mortgage Loan’s requirements and the borrower’s credit history, income, assets and liabilities. For a borrower who seeks financing through a Mortgage Loan originator’s higher-priced subprime lending channel, the borrower should be directed towards or offered the mortgage loan originator’s standard mortgage line if the borrower is able to qualify for one of the standard products;

(xlvi)

The methodology used in underwriting the extension of credit for each Subgroup I-1 Mortgage Loan did not rely solely on the extent of the borrower’s equity in the collateral as the principal determining factor in approving such extension of credit. The methodology employed objective criteria such as the borrower’s income, assets and liabilities, to the proposed mortgage payment and, based on such methodology, the Mortgage Loan’s originator made a reasonable determination that at the time of origination the borrower had the ability to make timely payments on the Mortgage Loan;

(xlvii)

No borrower under a Subgroup I-1 Mortgage Loan was charged “points and fees” in an amount greater than (a) $1,000 or (b) 5% of the principal amount of such Mortgage Loan, whichever is greater. For purposes of this representation, “points and fees” (x) include origination, underwriting, broker and finder’s fees and charges that the lender imposed as a condition of making the Loan, whether they are paid to the lender or a third party; and (y) exclude bona fide discount points, fees paid for actual services rendered in connection with the origination of the mortgage (such as attorneys’ fees, notaries fees and fees paid for property appraisals, credit reports, surveys, title examinations and extracts, flood and tax certification, and home inspections); the cost of mortgage insurance or credit-risk price adjustments; the costs of title, hazard, and flood insurance polices; state and local transfer taxes or fees; escrow deposits for the future payment of taxes and insurance premium; and other miscellaneous fees and charges, which miscellaneous fee and charges, in total, do not exceed 0.25% of the loan amount;

(xlviii)

With respect to any Subgroup I-1 Mortgage Loan originated on or after August 1, 2004, neither the related mortgage nor the related mortgage note requires the borrower to submit to arbitration to resolve any dispute arising out of or relating in any way to the Mortgage Loan transaction;

(xlix)

no Subgroup I-1 Mortgage Loan is secured by a manufactured housing unit;

(l)

No Subgroup I-1 Mortgage Loan has an original principal balance that exceeds the applicable limit in the table below; and

	Maximum Original Loan Amount
Number of Units	Continental Unites States or Puerto Rico	Alaska, Guam, Hawaii or Virgin Island
1	$417,000	$625,500
2	$533,850	$800,775
3	$645,300	$967,950
4	$801,950	$1,202,925

(li)

No Subgroup I-1 Mortgage Loan is “seasoned.”

The Certificates are limited in right of payment to certain collections and recoveries respecting the related Group I Loans and payments received pursuant to the Group I Cap 1 Agreement, the Group I Cap 2 Agreement and the Group I Swap Agreement, all as more specifically set forth herein and in the Agreement.

Mortgage Asset Securitization Transactions, Inc., as Depositor

Principal in respect of this Certificate is distributable monthly as set forth herein. Accordingly, the Certificate Principal Balance at any time may be less than the Certificate Principal Balance as set forth herein. This Certificate does not evidence an obligation of, or an interest in, and is not guaranteed by the Depositor, the Transferor, the Master Servicer, the Trust Administrator, the Custodian or the Trustee referred to below or any of their respective affiliates. Neither this Certificate nor the Mortgage Loans are guaranteed or insured by any governmental agency or instrumentality.

This certifies that CEDE & CO. is the registered owner of the Percentage Interest evidenced by this Certificate in certain monthly distributions with respect to a Trust Fund consisting of the Group I Loans and Group II Loans deposited by Mortgage Asset Securitization Transactions, Inc. (the “Depositor”). This Certificate is primarily backed by the Group I Loans deposited by the Depositor. The Trust Fund was created pursuant to a Pooling and Servicing Agreement dated as of the Cut-off Date specified above (the “Agreement”) among the Depositor, UBS Real Estate Securities Inc., as transferor (the “Transferor”), Xxxxx Fargo Bank, N.A., as master servicer (in such capacity, the “Master Servicer”), as trust administrator (in such capacity, the “Trust Administrator”), and as custodian (in such capacity, the “Custodian”), and U.S. Bank National Association, as trustee (the “Trustee”). Distributions on this Certificate will be made primarily from collections on the Group I Loans pursuant to the terms of the Agreement. To the extent not defined herein, the capitalized terms used herein have the meanings assigned in the Agreement. This Certificate is issued under and is subject to the terms, provisions and conditions of the Agreement, to which Agreement the Holder of this Certificate by virtue of the acceptance hereof assents and by which such Holder is bound.

No transfer of an ERISA-Restricted Certificate shall be made unless the Trust Administrator shall have received either (i) a representation letter from the transferee of such ERISA-Restricted Certificate, acceptable to and in form and substance satisfactory to the Trust Administrator, to the effect that such transferee is not an employee benefit plan or arrangement subject to Section 406 of ERISA or Section 4975 of the Code or an entity whose underlying assets include such plan’s or arrangement’s assets (a “Plan”), or a person acquiring such Certificate for, on behalf of or with the assets of, such Plan which representation letter shall not be an expense of the Trust Administrator or the Trust Fund, (ii) if the purchaser is an insurance company and the ERISA-Restricted Certificate has been the subject of an ERISA-Qualifying Underwriting, a representation that the purchaser is an insurance company which is purchasing such Certificates with funds contained in an “insurance company general account” (as such term is defined in Section V(e) of Prohibited Transaction Class Exemption 95-60 (“PTCE 95-60”)) and that the purchase and holding of such Certificate are covered under Sections I and III of PTCE 95-60 or (iii) in the case of any such ERISA-Restricted Certificate presented for registration in the name of a Plan or a person acquiring such Certificate for, on behalf of or with the assets of, such a Plan (a "Benefit Plan Investor"), an Opinion of Counsel satisfactory to the Trust Administrator to the effect that the purchase or holding of such Certificate will not result in prohibited transactions under Section 406 of ERISA and/or Section 4975 of the Code and will not subject the Trustee, the Transferor, the Depositor, the Master Servicer or the Trust Administrator to any obligation in addition to those undertaken in this Agreement, which Opinion of Counsel shall not be an expense of such parties.

In the event that a representation is violated, or any attempt to transfer an ERISA-Restricted Certificate to a Benefit Plan Investor is attempted without the delivery to the Trust Administrator of the Opinion of Counsel described above, the attempted transfer or acquisition of this certificate shall be void and of no effect.

Reference is hereby made to the further provisions of this Certificate set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if set forth at this place.

Any distribution of the proceeds of any remaining assets of the Trust Fund will be made only upon presentment and surrender of this Class [I-]R[-X] Certificate at the Corporate Trust Office of the Trust Administrator.

Prior to registration of any transfer, sale or other disposition of this Certificate, the proposed transferee shall provide to the Trust Administrator (i) an affidavit to the effect that such transferee is any Person other than a Disqualified Organization or the agent (including a broker, nominee or middleman) of a Disqualified Organization, and (ii) a certificate that acknowledges that (A) the Class [I-]R[-X] Certificates have been designated as a residual interest in a REMIC, (B) it will include in its income a pro rata share of the net income of the Trust Fund and that such income may be an “excess inclusion,” as defined in the Code, that, with certain exceptions, cannot be offset by other losses or benefits from any tax exemption, and (C) it expects to have the financial means to satisfy all of its tax obligations including those relating to holding the Class [I-]R[-X] Certificates. Notwithstanding the registration in the Certificate Register of any transfer, sale or other disposition of this Certificate to a Disqualified Organization or an agent (including a broker, nominee or middleman) of a Disqualified Organization, such registration shall be deemed to be of no legal force or effect whatsoever and such Person shall not be deemed to be a Certificateholder for any purpose, including, but not limited to, the receipt of distributions in respect of this Certificate.

This Certificate is one of a duly authorized issue of Certificates designated as Mortgage Asset Securitization Transactions, Inc. MASTR Adjustable Rate Mortgages Trust 2007-1, Mortgage Pass-Through Certificates, of the Series specified on the face hereof (herein collectively called the “Certificates”), and representing a beneficial ownership interest in the Trust Fund created by the Agreement.

The Certificateholder, by its acceptance of this Certificate, agrees that it will look solely to the funds on deposit in the Distribution Account for payment hereunder and that the Trust Administrator is not liable to the Certificateholders for any amount payable under this Certificate or the Agreement or, except as expressly provided in the Agreement, subject to any liability under the Agreement.

This Certificate does not purport to summarize the Agreement and reference is made to the Agreement for the interests, rights and limitations of rights, benefits, obligations and duties evidenced thereby, and the rights, duties and immunities of the Trust Administrator.

Pursuant to the terms of the Agreement, a distribution will be made on the 25th day of each month or, if such 25th day is not a Business Day, the Business Day immediately following (the “Distribution Date”), commencing on the first Distribution Date specified on the face hereof, to the Person in whose name this Certificate is registered at the close of business on the applicable Record Date in an amount equal to the product of the Percentage Interest evidenced by this Certificate and the amount required to be distributed to Holders of Certificates of the Class to which this Certificate belongs on such Distribution Date pursuant to the Agreement. [For the Class I-1A, Class I-2A1, Class I-2A2, Class I-2A4, and Group I Mezzanine Certificates only] [The Record Date applicable to each Distribution Date is the Business Day immediately preceding the related Distribution Date] [provided, that with respect to Class I-1A, Class I-2A1, Class I-2A2 and Class I-2A4 Certificates and the first Distribution Date the Record Date is the Closing Date.] [For the classes other than the Class I-1A, Class I-2A1, Class I-2A2, Class I-2A4, and Group I Mezzanine Certificates only] [The Record Date applicable to each Distribution Date is the last Business Day of the month immediately preceding the month in which the related Distribution Date occurs].

Distributions on this Certificate shall be made by wire transfer of immediately available funds to the account of the Holder hereof at a bank or other entity having appropriate facilities therefor, if such Certificateholder shall have so notified the Trust Administrator in writing at least five Business Days prior to the related Record Date and such Certificateholder shall satisfy the conditions to receive such form of payment set forth in the Agreement, or, if not, by check mailed by first class mail to the address of such Certificateholder appearing in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the Corporate Trust Office of the Trust Administrator or such other location specified in the notice to Certificateholders of such final distribution.

The Agreement permits, with certain exceptions therein provided, the amendment thereof and the modification of the rights and obligations of the Trust Administrator and the rights of the Certificateholders under the Agreement at any time by the Transferor, the Depositor, the Master Servicer, the Trust Administrator, the Custodian and the Trustee with the consent of the Holders of Certificates affected by such amendment evidencing the requisite Percentage Interest, as provided in the Agreement. Any such consent by the Holder of this Certificate shall be conclusive and binding on such Holder and upon all future Holders of this Certificate and of any Certificate issued upon the transfer hereof or in exchange therefor or in lieu hereof whether or not notation of such consent is made upon this Certificate. The Agreement also permits the amendment thereof, in certain limited circumstances, without the consent of the Holders of any of the Certificates.

As provided in the Agreement and subject to certain limitations therein set forth, the transfer of this Certificate is registrable in the Certificate Register of the Trust Administrator upon surrender of this Certificate for registration of transfer at the offices that the Trust Administrator designates for such purposes, accompanied by a written instrument of transfer in form satisfactory to the Trust Administrator and the Certificate Registrar duly executed by the holder hereof or such holder’s attorney duly authorized in writing, and thereupon one or more new Certificates of the same Class in authorized denominations and evidencing the same aggregate Percentage Interest in the Trust Fund will be issued to the designated transferee or transferees.

The Certificates are issuable only as registered Certificates without coupons in denominations specified in the Agreement. As provided in the Agreement and subject to certain limitations therein set forth, Certificates are exchangeable for new Certificates of the same Class in authorized denominations and evidencing the same aggregate Percentage Interest, as requested by the Holder surrendering the same.

No service charge will be made for any such registration of transfer or exchange, but the Trust Administrator may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

The Depositor, the Master Servicer, the Trust Administrator and the Trustee and any agent of the Depositor, the Master Servicer, the Trust Administrator or the Trustee may treat the Person in whose name this Certificate is registered as the owner hereof for all purposes, and neither the Depositor, the Master Servicer, the Trust Administrator, the Trustee, nor any such agent shall be affected by any notice to the contrary.

On any Distribution Date on which the latest of each of the following has occurred: (i) the aggregate Principal Balance of the Group I MTA Loans, after giving effect to distributions to be made on that Distribution Date, is less than 10% of the aggregate Principal Balance of the Group I MTA Loans as of the Cut-Off Date, (ii) the aggregate Principal Balance of the Group I LIBOR Loans that have prepayment penalties, after giving effect to distributions to be made on that Distribution Date, is less than 10% of the aggregate Principal Balance of such loans as of the Cut-Off Date and (iii) the aggregate Principal Balance of the Group I LIBOR Loans that do not have prepayment penalties, after giving effect to distributions to be made on that Distribution Date, is less than 10% of the aggregate Principal Balance of such loans as of the Cut-Off Date, all remaining Group I Loans and all property acquired in respect of the Group I Loans may be purchased at a purchase price determined as provided in the Agreement pursuant to the procedures specified in Article XI of the Agreement.

In no event, however, will the trust created by the Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants living at the date of the Agreement of a certain person named in the Agreement.

STATE OF

ss.:
COUNTY OF

)

The undersigned, being first duly sworn, deposes and says as follows:

The undersigned is an officer of _______, the proposed Transferee of an Ownership Interest in a Class [[I-]R[-X]][II-A-[_]R] Certificate (the “Certificate”) issued pursuant to the Pooling and Servicing Agreement dated as of December 1, 2006 (the “Agreement”) among Mortgage Asset Securitization Transactions, Inc., as depositor, UBS Real Estate Securities Inc., as transferor (the “Transferor”), Xxxxx Fargo Bank, N.A., as master servicer (in such capacity, the “Master Servicer”), as trust administrator (in such capacity, the “Trust Administrator”), and as custodian (in such capacity, the “Custodian”) and U.S. Bank National Association, as trustee (the “Trustee”). Capitalized terms used, but not defined herein or in Exhibit 1 hereto, shall have the meanings ascribed to such terms in the Agreement. The Transferee has authorized the undersigned to make this affidavit on behalf of the Transferee.

The Transferee is, as of the date hereof, and will be, as of the date of the Transfer, a Permitted Transferee. The Transferee is acquiring its Ownership Interest in the Certificate either (i) for its own account or (ii) as nominee, trustee or agent for another Person and has attached hereto an affidavit from such Person in substantially the same form as this affidavit. The Transferee has no knowledge that any such affidavit is false.

The Transferee has been advised of, and understands that (i) a tax will be imposed on Transfers of the Certificate to Persons that are Disqualified Organizations; (ii) such tax will be imposed on the transferor, or, if such Transfer is through an agent (which includes a broker, nominee or middleman) for a Person that is a Disqualified Organization, on the agent; and (iii) the Person otherwise liable for the tax shall be relieved of liability for the tax if the subsequent Transferee furnished to such Person an affidavit that such subsequent Transferee is not a Disqualified Organization and, at the time of Transfer, such Person does not have actual knowledge that the affidavit is false.

The Transferee has been advised of, and understands that a tax will be imposed on a “pass-through entity” holding the Certificate if at any time during the taxable year of the pass-through entity a Person that is a Disqualified Organization is the record holder of an interest in such entity. The Transferee understands that such tax will not be imposed for any period with respect to which the record holder furnishes to the pass-through entity an affidavit that such record holder is not a Disqualified Organization and the pass-through entity does not have actual knowledge that such affidavit is false; provided, that a pass-through entity which is an “electing large partnership” under the Code will be subject to tax in all events. (For this purpose, a “pass-through entity” includes a regulated investment company, a real estate investment trust or common trust fund, a partnership, trust or estate, and certain cooperatives and, except as may be provided in Treasury Regulations, persons holding interests in pass-through entities as a nominee for another Person.) The Transferee further understands that it may incur tax liabilities with respect to the holding of the Certificate in excess of cash flows generated thereby.

The Transferee has reviewed the provisions of Section 5.02(c) of the Agreement (attached hereto as Exhibit 2 and incorporated herein by reference) and understands the legal consequences of the acquisition of an Ownership Interest in the Certificate including, without limitation, the restrictions on subsequent Transfers and the provisions regarding voiding the Transfer and mandatory sales. The Transferee expressly agrees to be bound by and to abide by the provisions of Section 5.02(c) of the Agreement and the restrictions noted on the face of the Certificate. The Transferee understands and agrees that any breach of any of the representations included herein shall render the Transfer to the Transferee contemplated hereby null and void.

The Transferee agrees to require a Transfer Affidavit from any Person to whom the Transferee attempts to Transfer its Ownership Interest in the Certificate, and in connection with any Transfer by a Person for whom the Transferee is acting as nominee, trustee or agent, and the Transferee will not Transfer its Ownership Interest or cause any Ownership Interest to be Transferred to any Person that the Transferee knows is not a Permitted Transferee. In connection with any such Transfer by the Transferee, the Transferee agrees to deliver to the Trust Administrator a certificate substantially in the form set forth as Exhibit I to the Agreement (a “Transferor Certificate”) to the effect that such Transferee has no actual knowledge that the Person to which the Transfer is to be made is not a Permitted Transferee.

The Transferee does not have the intention to impede the assessment or collection of any tax legally required to be paid with respect to the Certificate. The Transferee historically has paid its debts as they have become due and intends to do so in the future. The Transferee understands that the taxable income and tax liability with respect to this Certificate will exceed distributions with respect to the Certificate in some or all periods and intends to pay all taxes with respect to the Certificate as they become due.

The Transferee’s taxpayer identification number is __________.

The Transferee is a U.S. Person as defined in Code Section 7701(a)(30) or is not a U.S. Person and has furnished the Transferor and the Trust Administrator with a duly completed Internal Revenue Service Form W-8ECI or any applicable successor form.

10.

The Transferee is aware that the Certificate may be a “noneconomic residual interest” within the meaning of proposed Treasury regulations promulgated pursuant to the Code and that the transferor of a noneconomic residual interest will remain liable for any taxes due with respect to the income on such residual interest, unless no significant purpose of the transfer was to impede the assessment or collection of tax.

11.

The Transferee will not cause income with respect to the Certificate to be attributable to a foreign permanent establishment or fixed base, within the meaning of an applicable income tax treaty, of the Transferee or any other U.S. Person.

12.

Check one of the following paragraphs:

□ The present value of the anticipated tax liabilities associated with holding the Certificate, as applicable, does not exceed the sum of:

(i)

the present value of any consideration given to the Transferee to acquire such Certificate;

(ii)

the present value of the expected future distributions on such Certificate; and

(iii)

the present value of the anticipated tax savings associated with holding such Certificate as the related REMIC generates losses.

For purposes of this calculation, (i) the Transferee is assumed to pay tax at the highest rate currently specified in Section 11(b) of the Code (but the tax rate in Section 55(b)(1)(B) of the Code may be used in lieu of the highest rate specified in Section 11(b) of the Code if the Transferee has been subject to the alternative minimum tax under Section 55 of the Code in the preceding two years and will compute its taxable income in the current taxable year using the alternative minimum tax rate) and (ii) present values are computed using a discount rate equal to the short-term Federal rate prescribed by Section 1274(d) of the Code for the month of the transfer and the compounding period used by the Transferee.

□ The transfer of the Certificate complies with U.S. Treasury Regulations Sections 1.860E-1(c)(5) and (6) and, accordingly,

(i)

the Transferee is an “eligible corporation,” as defined in U.S. Treasury Regulations Section 1.860E-1(c)(6)(i), as to which income from the Certificate will only be taxed in the United States;

(ii)

at the time of the transfer, and at the close of the Transferee’s two fiscal years preceding the year of the transfer, the Transferee had gross assets for financial reporting purposes (excluding any obligation of a person related to the Transferee within the meaning of U.S. Treasury Regulations Section 1.860E-1(c)(6)(ii)) in excess of $100 million and net assets in excess of $10 million;

(iii)

the Transferee will transfer the Certificate only to another “eligible corporation,” as defined in U.S. Treasury Regulations Section 1.860E-1(c)(6)(i), in a transaction that satisfies the requirements of U.S. Treasury Regulations Sections 1.860E-1(c)(4)(i), (ii) and (iii) and Section 1.860E-1(c)(5); and

(iv)

the Transferee determined the consideration paid to it to acquire the Certificate based on reasonable market assumptions (including, but not limited to, borrowing and investment rates, prepayment and loss assumptions, expense and reinvestment assumptions, tax rates and other factors specific to the Transferee) that it has determined in good faith.

□ None of the above.

13.

The Transferee is either: (i) not an employee benefit plan or other retirement arrangement subject to Section 406 of ERISA and/or Section 4975 of the Code, or a person acting for, on behalf of or with the assets of, any such plan or arrangement, (ii) if the purchaser is an insurance company, the purchaser is an insurance company which is purchasing such Certificate with funds contained in an “insurance company general account” (as such term is defined in Section V(e) of Prohibited Transaction Class Exemption 95-60 (“PTCE 95-60”)) and the purchase and holding of such Certificate is covered under Sections I and III of PTCE 95-60, or (iii) the Transferee has delivered to the Trust Administrator an Opinion of Counsel satisfactory to the Trust Administrator to the effect that the purchase or holding of such Certificate will not result in prohibited transactions under Section 406 of ERISA and/or Section 4975 of the Code and will not subject the Trustee, the Transferor, the Depositor, the Master Servicer or the Trust Administrator to any obligation in addition to those undertaken in the Agreement, which Opinion of Counsel shall not be an expense of such parties or the Trust Fund.

“Disqualified Organization”: A Person specified in clauses (i)-(iv) of the definition of “Permitted Transferee.”

“Permitted Transferee”: Any person other than (i) the United States, any State or political subdivision thereof, or any agency or instrumentality of any of the foregoing, (ii) a foreign government, International Organization or any agency or instrumentality of either of the foregoing, (iii) an organization (except certain farmers’ cooperatives described in Section 521 of the Code) which is exempt from tax imposed by Chapter 1 of the Code (including the tax imposed by Section 511 of the Code on unrelated business taxable income) on any excess inclusions (as defined in Section 860E(c)(l) of the Code) with respect to any Residual Certificate, (iv) rural electric and telephone cooperatives described in Section 1381(a)(2)(C) of the Code, (v) a Person that is not a citizen or resident of the United States, a corporation, partnership (except as provided in applicable Treasury Regulations), or other entity created or organized in or under the laws of the United States or any state thereof or the District of Columbia, an estate whose income is subject to United States federal income tax purposes regardless of its source or a trust if a court within the United States is able to exercise primary supervision over the administration of the trust and one or more persons described in this clause (v) have the authority to control all substantial decisions of the trust (or, to the extent provided in applicable Treasury Regulations, certain trusts in existence on September 20, 1996 which are eligible to elect to be treated as United States persons) unless such Person has furnished the transferor and the Trust Administrator with a duly completed Internal Revenue Service Form W-8ECI or any applicable successor form, (vi) any Person with respect to whom income on any residual certificate is attributable to a foreign permanent establishment or fixed base, within the meaning of an applicable treaty, of such Person or any other U.S. Person and (vii) any other Person so designated by the Depositor based upon an Opinion of Counsel that the Transfer of an Ownership Interest in a Residual Certificate to such Person may cause a REMIC hereunder to fail to qualify as a REMIC at any time that the Certificates are outstanding. The terms “United States,” “State” and “International Organization” shall have the meanings set forth in Section 7701 of the Code or successor provisions.

(i)

(ii)

(iii)

(iv)

Any attempted or purported Transfer of any Ownership Interest in a Residual Certificate in violation of the provisions of this Section 5.02(c) shall be absolutely null and void and shall vest no rights in the purported Transferee. If any purported transferee shall become a Holder of a Residual Certificate in violation of the provisions of this Section 5.02(c), then the last preceding Permitted Transferee shall be restored to all rights as Holder thereof retroactive to the date of registration of Transfer of such Residual Certificate. The Trust Administrator shall be under no liability to any Person for any registration of Transfer of a Residual Certificate that is in fact not permitted by Section 5.02(b) and this Section 5.02(c) or for making any payments due on such Certificate to the Holder thereof or taking any other action with respect to such Holder under the provisions of this Agreement so long as the Transfer was registered after receipt of the related Transfer Affidavit, Transferor Certificate and either the Rule 144A Letter or the Investment Letter. The Trust Administrator shall be entitled but not obligated to recover from any Holder of a Residual Certificate that was in fact not a Permitted Transferee at the time it became a Holder or, at such subsequent time as it became other than a Permitted Transferee, all payments made on such Residual Certificate at and after either such time. Any such payments so recovered by the Trust Administrator shall be paid and delivered by the Trust Administrator to the last preceding Permitted Transferee of such Certificate.

(v)

The restrictions on Transfers of a Residual Certificate set forth in this Section 5.02(c) shall cease to apply (and the applicable portions of the legend on a Residual Certificate may be deleted) with respect to Transfers occurring after delivery to the Trust Administrator of an Opinion of Counsel, which Opinion of Counsel shall not be an expense of the Trust Fund, the Trustee, the Loan Seller, the Transferors, the Master Servicer or the Trust Administrator, to the effect that the elimination of such restrictions will not cause a REMIC hereunder to fail to qualify as a REMIC at any time that the Certificates are outstanding or result in the imposition of any tax on the Trust Fund, a Certificateholder or another Person. Each Person holding or acquiring any Ownership Interest in a Residual Certificate hereby consents to any amendment of this Agreement which, based on an Opinion of Counsel furnished to the Trust Administrator, is reasonably necessary (a) to ensure that the record ownership of, or any beneficial interest in, a Residual Certificate is not transferred, directly or indirectly, to a Person that is not a Permitted Transferee and (b) to provide for a means to compel the Transfer of a Residual Certificate which is held by a Person that is not a Permitted Transferee to a Holder that is a Permitted Transferee.
