W I T N E S S E T H T H A T

In consideration of the mutual agreements herein contained, the parties hereto agree as follows:

PRELIMINARY STATEMENT

The Depositor is the owner of the Trust Fund that is hereby conveyed to the Trustee in return for the Certificates. The Trust Fund is being conveyed to the Trustee to create a trust for the benefit of the Certificateholders. As provided herein, an election shall be made that the Trust Fund (exclusive of (i) the right to receive and the obligation to pay Net Rate Carryover Amounts to the extent such amounts would result in the payment of interest reflecting an interest rate exceeding the REMIC Maximum Rate, (ii) the Carryover Reserve Fund, (iii) the Cap Contract (iv) the Cap Account, and (v) the Supplemental Interest Trust (collectively, the “Excluded Trust Assets”)) be treated for federal income tax purposes as comprising five real estate mortgage investment conduits under Section 860D of the Code (each a “REMIC” or, in the alternative the “Subsidiary REMIC, 8; the “Middle REMIC,” the “Master REMIC”, the “Class C REMIC,” and the “Class P REMIC”). Any inconsistencies or ambiguities in this Agreement or in the administration of this Agreement shall be resolved in a manner that preserves the validity of such REMIC elections.

Each Certificate, other than the Class R, Class R-X, Class P, and Class C Certificates, represents ownership of a regular interest in the Master REMIC for purposes of the REMIC Provisions. In addition, each Certificate, other than the Class R, Class R-X, Class P, and Class C Certificates, represents the right to receive payments with respect to any Net Rate Carryover Amounts to the extent such amounts reflect an interest rate greater than the REMIC Maximum Rate. The Class R Certificate represents ownership of the sole Class of residual interest in each of the Subsidiary REMIC, the Middle REMIC, and the Master REMIC for purposes of the REMIC Provisions. The Class R-X Certificate represents ownership of the sole Class of residual interest in each of the Class C REMIC and the Class P REMIC.

The Class C REMIC shall hold as its assets the uncertificated Class C interest in the Master REMIC and the Class P REMIC shall hold as its assets the uncertificated Class P interest in the Master REMIC. Each such interest is hereby designated as a regular interest in the Master REMIC, for purposes of the REMIC Provisions. The Master REMIC shall hold as its assets the uncertificated interests in the Middle REMIC, other than the MT-R interest, and each such interest is hereby designated as a regular interest in the Middle REMIC for purposes of the REMIC Provisions. The Middle REMIC shall hold as its assets the uncertificated interests in the Subsidiary REMIC, other than the LT-R interest, and each such interest is hereby designated as a regular interest in the Subsidiary REMIC. The Subsidiary REMIC shall hold as its assets the property of the Trust Fund other than th e interests in the Subsidiary REMIC and the Middle REMIC and the uncertificated Class C interest and the uncertificated Class P interest, and the Excluded Trust Assets.

The startup day for each REMIC created hereby for purposes of the REMIC Provisions is the Closing Date. In addition, for purposes of the REMIC Provisions, the latest possible maturity date for each regular interest in each REMIC created hereby is the Latest Possible Maturity Date.

Subsidiary REMIC:

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

(vi)

sixth, to the MT-Group 1, MT-Group 2, MT-Group 3, and the MT-Group 4 Interests concurrently, as follows:

(a)

(b)

To the MT1-Group 2 Interest until its principal balance equals the difference between (I) 50% of the Loan Group Balance for Loan Group 2 for the next Distribution Date, minus (II) the aggregate principal balance of the MT-2A1 and MT-SC2 Interests on such Distribution Date, taking into account the distributions under priorities (i) through (v) above;

(c)

To the MT1-Group 3 Interest until its principal balance equals the difference between (I) 50% of the Loan Group Balance for Loan Group 3 for the next Distribution Date, minus (II) the aggregate principal balance of the MT-3A1, MT-3A2, MT-3A3, and MT-SC3 Interests on such Distribution Date, taking into account the distributions under priorities (i) through (v) above;

As of the date hereof, recordation is not required in any state by either Rating Agency to obtain the initial rating on the Certifica tes (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 2006-OA1” and U.S. Bank National Association is hereby appointed as Trustee in accordance with the provisions of this Agreement.

(d)

[Reserved].

(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.

(f)

The Depositor hereby directs the Trust Administrator to execute, deliver and perform its obligations under the Cap Contract. The Transferor, the Depositor, the Master Servicer, the Trustee and the Holders of the Senior Certificates (other than Group 3 Certificates) and the Mezzanine Certificates by their acceptance of such Certificates acknowledge and agree that the Trust Administrator shall execute, deliver and perform its obligations under the Cap Contract and shall do so solely in its capacity as Trust Administrator, 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 Trust Administrator’s execution of the Cap Contract, 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. 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 and the Trustee.

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 Sec tion 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 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, 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 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 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 Re quest 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 Trus tee 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 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 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 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 applicab le representation or warranty.

Upon discovery by any of the Depositor, 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 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 (xiv), (xxxv), (xxxvi), (xxxvii), (xxxviii), (xxxix) and (xl) 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 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 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 and the Trustee for any expenses reasonably incurred by the Master Servicer, the NIMS 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 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 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 subst ituted 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 D ate 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 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 obl igation 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 and the Certificateholders.

Section 2.04

The Depositor hereby represents and warrants to the Trustee, the Trust Administrator, the NIMS 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 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, the party discovering such breach shall give prompt written notice to the other parties hereto and to each Rating Agency.

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. The Master Servicer shall reconcile the results of its Mortgage Loan monitoring with the actual remittances of the Servicers to the Collection Account pursuant to the applicable Servicing Agreements.

In accordance with the standards of the preceding paragraph and to the extent the related Servicer does not make such advance, the Master Servicer shall advance or cause to be advanced funds as necessary for the purpose of effecting the payment of taxes and assessments on the Mortgaged Properties, which advances shall be reimbursable in the first instance from related collections from the Mortgagors pursuant to Section 3.07, and further as provided in Section 3.08. The costs incurred by the Master Servicer, if any, in effecting the timely payment of taxes and assessments on the Mortgaged Properties and related insurance premiums shall not, for the purpose of calculating monthly distributions to the Certificateholders, be added to the Scheduled Principal Balances of the related Mortgage Loans, notwithstanding that the terms of such Mortgage Loans so permit.

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 and the Trustee thereof and the Master Servicer shall issue s uch notice or take such other action as it deems appropriate.

Such enforcement, including, without limitation, the leg al 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 accor dance 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.

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.

Section 4.07

Distributions from the Cap Account.

On each Distribution Date on or prior to the earlier of (a) the Cap Contract Scheduled Termination Date and (b) the date on which the aggregate Class Principal Balance of the Offered Certificates is reduced to zero, amounts on deposit in the Cap Account from the Cap Contract will be withdrawn therefrom and, following all other distributions on such Distribution Date, distributed to the Certificates, to the extent needed to pay any Unpaid Realized Loss Amount or Net Rate Carryover on the related Classes of Certificates for such Distribution Date after all other distributions on such Distribution Date, sequentially as follows:

(i)

first, concurrently, to the Group 1 Certificates, Group 2 Certificates, Group 3 Certificates and Group 4 Certificates, pro rata based on the aggregate Unpaid Realized Loss Amount for the Group 1 Certificates, Group 2 Certificates, Group 3 Certificates and Group 4 Certificates:

(a)

(iii)

third, concurrently, to the Class X and Class XN Certificates, pro rata, in an amount equal to the amount of any remaining Net Rate Carryover for each such Class;

(iv)

fourth, concurrently, to the Classes of Senior Certificates (other than the Interest Only Certificates), pro rata, in an amount equal to the amount of any remaining Net Rate Carryover for each such Class;

(vi)

sixth, to the Class C Certificates, any remaining amount.

(b)

For federal income tax purposes, the Trust Administrator shall treat the Holders of Certificates (other than the Class P, Class C, Class R-X and Class R Certificates) as having entered into a notional principal contract with respect to the Holders of the Class C Certificates. Pursuant to each such notional principal contract, the Holder of the Class C Certificates shall be treated as having agreed to pay Net WAC Rate Carryover Amounts (to the extent such amounts reflect an interest rate greater than the REMIC Maximum Rate) and to pay the Excluded Inerest Payments to the No-Delay Certificates in accordance with their respective entitlements to receive such amounts to the Holders of the Certificates (other than the Class C, Class P, Class R and Class R-X Certificates) in accordance with the terms of this Agreement. Any payments to the 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 Code Section 860G(a)(1). Thus, each Certificate (other than the Class C, Class P, Class R and Class R-X Certificates) shall be treated as representing not only ownership of regular interests in the Master REMIC, but also ownership of an interest in (and with respect to the Class C Certificate, an obligation 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.

Section 4.08

Determination of MTA

On each MTA Determination Date for a Class of 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 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 MTA Certificates or (y) the Reserve Interest Rate.

If on any MTA Determination Date for a Class of 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 MTA certificates that is based on comparable information. When the Trust Administrator chooses a new index for the 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 b e 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 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 MTA Certificates for the related Distribution Date to Certificate Owners or Holders of MTA Certificates who place a telephone call to the Trust Administrator at ###-###-#### and make a request therefor.

Section 4.09

Determination of LIBOR.

On the first LIBOR Determination Date, LIBOR for any Class of LIBOR Certificates shall be equal to the Initial LIBOR Rate, and on each LIBOR Determination Date thereafter for any Class of 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.

If on any LIBOR Determination Date for any Class of 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 Adm inistrator 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 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 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 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 ###-###-#### and make a request therefor.

THE CERTIFICATES

Section 5.01

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 10.02 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 Cer tificates 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 5.02

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 5.06 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 substanti ally 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 sentenc e, 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, or a person acting for, on behalf of or with the assets of, any such plan or arrangement, (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 co mpany 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 purp oses 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 an employee benefit plan or other retirement arrangement subject to ERISA or the Code 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 5.02(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 Cap Certificate prior to the termination of the Interest Rate Cap 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 Cap Certificate are eligible for exemptive relief under Prohibited Transaction Class Exemption (“PTCE”) 84-14, PTCE 90-1, PTCE 91-38, PTCE 95-60 or PTCE 96-23. Notwithstanding anything else to the contrary herein, any purported transfer of an ERISA-Restricted Cap Certi ficate 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 Cap 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 Cap 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 Cap 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 Cap Certificate that is in fact not permitted by this Section 5.02(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 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 pro visions 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 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 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 Agre ement 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 5.02 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 e xercising 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 5.03

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 5.03, 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 5.03 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 5.04

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 5.05

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 he ld 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.

Upon the receipt by the Master Servicer of such written notice, all authority and power of the Master Servicer under this Agreement, whether with respect to the Certificates, the Mortgage Loans, the Servicing Agreements, REO Property or under any other related agreements (but only to the extent that such other agreements relate to the Mortgage Loans or related REO Property) shall, subject to Section 7.02, automatically and without further action pass to and be vested in the Trustee pursuant to this Section 7.01; and, without limitation, the Trustee is hereby authorized and empowered to execute and deliver, on behalf of the Master Servicer as attorney-in-fact or othe rwise, any and all documents and other instruments and to do or accomplish all other acts or things necessary or appropriate to effect the purposes of such notice of termination, whether to complete the transfer and endorsement or assignment of the Mortgage Loans and related documents, or otherwise. The Master Servicer agrees to cooperate with the Trustee in effecting the termination of the Master Servicer’s rights and obligations hereunder, including, without limitation, the transfer to the Trustee of (i) the Mortgage Files and all other property and amounts which are then or should be part of the Trust or which thereafter become part of the Trust; and (ii) originals or copies of all documents of the Master Servicer reasonably requested by the Trustee to enable it to assume the Master Servicer’s duties thereunder. In addition to any other amounts which are then, or, notwithstanding the termination of its activities under this Agreement, may become payable to the Master Servicer under t his Agreement, the Master Servicer shall be entitled to receive, out of any amount received on account of a Mortgage Loan or related REO Property, that portion of such payments which it would have received as reimbursement under this Agreement if notice of termination had not been given. 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.

If the Master Servicer and the Trust Administrator are the same Person, then at any time the Master Servicer is terminated pursuant to Section 7.01 hereof, the Trust Administrator shall likewise be removed as trust administrator hereunder.

Section 7.02

Trustee to Act; Appointment of Successor.

On and after the time the Master Servicer receives a notice of termination pursuant to Section 7.01 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 4.10. 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 7.01 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 4.10 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 Fannie Mae and Freddie 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 6.03 hereof incurred prior to termination of the Master Servicer under Section 7.01), 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 he reof, 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 withdra w 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 7.03

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, 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 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.

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 and the Certificateholders of such non-conforming instrument in the event the Trustee, after so requesting, does not receive a satisfactorily correcte d 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 7.02 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 pre ceding sentence.

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;

(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);

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, the Certificateholders, pursuant to the provisions of this Agreement, unless the NIMS 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.

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.

If the Master Servicer 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 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 8.06 and no notice to Certificateholders of the appointment of any co-trustee or separate trustee shall be required under Section 8.08.

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 8.10, 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 obligat ions (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 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.

Kennedy, the late ambassador of the United States to the Court of St. James, living on the date hereof or (b) the Latest Possible Maturity Date as defined in the Preliminary Statement. Subject to Section 3.10 hereof, the purchase by the Master Servicer, at the direction of the Majority Holder of the Class C Certificates, of all Mortgage Loans and each REO Property remaining in the Subsidiary REMIC shall be at a price (the “Termination Price”) equal to the greater of (i) the Principal Balance of the Mortgage Loans and the appraised value of any 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 the Subsidiary REMIC (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 the third paragraph of this Section 10.01) 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 Mortgage Loans and REO Properties, any accrued and unpaid Net WAC Carryover Amount; provided, however, such option may only be exercised if (i) the Termination Price is sufficient to pay all interest accrued on, as well as amo unts 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 (ii) the fair market value of the Mortgage Loans and REO Properties determined as described above is at least equal to the Principal Balance of the 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 REO Properties.

(b)

The Majority Holder of the Class C Certificates shall have the right to direct the Master Servicer to purchase the Trust Collateral pursuant to clause (i) of the preceding paragraph no later than the Determination Date in the month immediately preceding the Distribution Date on which the Certificates will be retired; provided, however, that the Majority Holder of the Class C Certificates may elect to direct the Master Servicer to purchase the Trust Collateral pursuant to clause (i) above only if the aggregate Principal Balance of the Mortgage Loans and each REO Property remaining in the Trust Fund at the time of such election is reduced to less than 1% of the aggregate Principal Balance of the Mortgage Loans as of the Cut-off Date. By acceptance of the Residual Certificates, the Holder of the Residual Certificates agrees for so long as any notes insured by the NIM S Insurer and secured by all or a portion of the Class C, Class P or Residual 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 C Certificates.

(c)

Notice of the liquidation of the Certificates shall be given promptly by the Trust Administrator by letter to Certificateholders, the NIMS Insurer and the Trustee mailed (a) in the event such notice is given in connection with the purchase of the Mortgage Loans and each REO Property by the Master Servicer, not earlier than the 10^th day and not later than the 20^th 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 Trust Fund will terminate and the final payment in respect of the Certificates will be made upon presentation and surrender of the related Certificates at the office of the Trust Administrator therein designated, (ii) the amount of any suc h final payment, (iii) that no interest shall accrue in respect of the Subsidiary or Middle REMIC Regular Interests or the 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 Certificates at the office of the Trust Administrator.

In the event such notice is given in connection with the purchase of all of the Mortgage Loans and each REO Property remaining in the Subsidiary REMIC 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 Date 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 maki ng 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, the Trust Administrator shall promptly release to the Master Servicer the Mortgage Files for the remaining Mortgage Loans, and the Trust Administrator shall execute all assignments, endorsements and other instruments necessary to effectuate such transfer.

(d)

Upon presentation of the Certificates by the Certificateholders on the final Distribution Date, the Trust Administrator shall distribute to each Certificateholder so presenting and surrendering its Certificates the amount otherwise distributable on such Distribution Date in accordance with Section 4.02 in respect of the Certificates so presented and surrendered. Any funds not distributed to any Holder or Holders of Certificates being retired on such Distribution Date because of the failure of such Holder or Holders to tender their 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 Certificates as to which notice has been given pursuant to this Section 10.01 shall not have been surrendered for cancellation within six months after the time specified in such notice, the T rust Administrator shall mail a second notice to the remaining non-tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such 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 Certificateholders concerning surrender of their Certificates. The costs and expenses of maintaining the funds in trust and of contacting such Certificateholders shall be paid out of the assets remaining in the Trust Fund. If within one year after the final notice any such 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 Certificateholders in or to such amounts shall thereupon cease. No interest shall accrue or be payable to any Certific ateholder on any amount held in trust by the Trust Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with this Section 10.01. 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 Certificates, the Trust Fund shall terminate.
