      share; and 

     

    WHEREAS,
      the Seller desires to sell to the Purchaser, and the Purchaser desires to

THIS POOLING AND SERVICING AGREEMENT, dated as of March 1, 2006, among MORTGAGE ASSET SECURITIZATION TRANSACTIONS, INC., a Delaware corporation, as depositor (the “Depositor”), UBS REAL ESTATE SECURITIES INC., a Delaware corporation, as transferor (the “Transferor”), WELLS FARGO BANK, N.A., a national banking association (“Wells Fargo”), as master servicer (in such capacity, the “Master Servicer”), as trust administrator (in such capacity, the “Trust Administrator”) and as custodian (in such capacity, the “Custodian”) and U.S. BANK NATIONAL ASSOCIATION, a national banking association, as trustee (in such capacity, the “Trustee”).

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.  The Trust Fund for federal income tax purposes shall consist of three REMICs (the “Subsidiary REMIC”, the “Middle REMIC” and the “Master REMIC”).  The “latest possible maturity date” for federal income tax purposes of all interests created hereby shall be the Latest Possible Maturity Date.  

The Subsidiary REMIC shall consist of all of the assets constituting the Trust Fund corresponding to Collateral Group 1, Collateral Group 2, Collateral Group 3, and Collateral Group 4 (exclusive of the Class P Prepayment Charges, the Cap Reserve Fund and the Cap Contract) and shall be evidenced by the uncertificated interests set forth below that shall be designated as REMIC regular interests (the “Subsidiary REMIC Regular Interests”).  In addition, the Subsidiary REMIC shall issue the Class A-LR Certificate and shall designate such interest as its sole class of residual interest.

The Middle REMIC shall hold as its assets the uncertificated REMIC regular interests issued by the Subsidiary REMIC.  The Middle REMIC shall issue the Class R-2 interest and shall designate such interest as its sole class of residual interest.  In addition, the Middle REMIC shall issue the uncertificated REMIC regular interests set forth below for the Middle REMIC (the “Middle REMIC Regular Interests”).

The Master REMIC shall consist of the Middle REMIC Regular Interests and shall be evidenced by the Classes of Certificates set forth below for the Master REMIC (which, except for the Class P, Class A-LR and Class A-UR Certificates and, in the case of the Class 1-A-13 Certificates, exclusive of the entitlement to receive payments from the Cap Reserve Fund, shall represent the “regular interests” in the Master REMIC) and the Class R-3 Interest as the single “residual interest” in the Master REMIC.   The Class A-UR Certificate shall not be considered a Certificate issued by the Master REMIC, but instead shall represent beneficial ownership of the Class R-2 and Class R-3 interests.

Subsidiary REMIC:

The Subsidiary REMIC Regular Interests, each of which is hereby designated a REMIC regular interest for federal income tax purposes, shall have the following principal balances, pass-through rates and corresponding Collateral Groups in the manner set forth in the following table:

____________________

(1)

Each LT1 Interest shall have a principal balance initially equal to 0.9% of the Group Subordinate Amount of its corresponding Collateral Group or Groups.  Each LT2 Interest shall have a principal balance initially equal to 0.1% of the Group Subordinate Amount of its corresponding Collateral Group.   The initial principal balance of each LT3 Interest shall equal the excess of the Group Balance of its corresponding Collateral Group or Groups over the sum of (i) the initial principal balances of the LT1 and LT2 Interests corresponding to such Collateral Group or Groups, (ii) the portion of the LT-15-PO or LT-30-PO Interest attributable to the Discount Loans in the Collateral Group or Groups corresponding to such LT3 Interest, and (iii) in the case of Collateral Group 1 the principal balance of the Class A-LR Certificate.

(2)

This Subsidiary REMIC interest shall not have any principal balance.

(3)

The LT-15-A-X Interest shall be entitled to receive all interest accrued at the related Stripped Interest Rate on each Non-Discount Mortgage Loan in Collateral Group 4.

(4)

The LT-30-A-X Interest shall be entitled to receive all interest accrued at the related Stripped Interest Rate on each Non-Discount Mortgage Loan in Collateral Groups 2 and 3.

(5)

The LT-15-PO Interest shall have an initial principal balance equal to the initial principal balance of the Class 15-PO Certificate.

(6)

The LT-30-PO Interest shall have an initial principal balance equal to the initial principal balance of the Class 30-PO Certificate.

Unless a Cross-over Situation (as defined below) exists, principal and Realized Losses arising with respect to each Collateral Group shall be allocated first to cause the LT1 and LT2 interests corresponding to such Collateral Group or Groups to equal 0.9% and 0.1% of the Group Subordinate Amount of such Collateral Group or Groups as of such Distribution Date and all excess principal and Realized Losses shall be allocated to the LT3 interest corresponding to such Collateral Group or Groups.  A LT1, LT2 or LT3 interest that is allocated principal on any Distribution Date shall receive such principal, and have its principal balance reduced by the amount of such principal, on such Distribution Date.  Similarly, a LT1, LT2 or LT3 interest that is allocated a Realized Loss on any Distribution Date shall have its principal balance reduced by the amount of such Realized Loss on such Distribution Date.  

A “Cross-over Situation” exists if on any Distribution Date (after taking into account distributions of principal and allocations of Realized Losses on such Distribution Date) the LT1 and LT2 interests corresponding to any Collateral Group or Groups are in the aggregate less than 1% of the Group Subordinate Amount of the Collateral Group or Groups to which they correspond.  In the event that a Cross-Over Situation exists on any Distribution Date, and the weighted average rate of the outstanding LT1 and LT2 interests related to a Class of Subordinate Certificates is less than the Pass-Through Rate for such class of Subordinate Certificates, a Principal Relocation Payment (as defined below) shall be made proportionately to such outstanding LT1 interests prior to any other distributions of principal from each such Collateral Group or Groups.  In the event that a Cross-Over Situation exists on any Distribution Date, and the weighted average rate of the outstanding LT1 and LT2 interests related to a Class of Subordinate Certificates is greater than the Pass-Through Rate for such class of Subordinate Certificates, a Principal Relocation Payment shall be made proportionately to such outstanding LT2 interests prior to any other distributions of principal from each such Collateral Group.  A “Principal Relocation Payment” is a distribution of principal that causes the Calculation Rate (as defined below) on the outstanding LT1 and LT2 interests related to a Class of Subordinate Certificates to equal the Pass-Through Rate for such class of Subordinate Certificates.  The “Calculation Rate” shall equal the product of (i) 10 and (ii) the weighted average rate of the outstanding Class LT1 and Class LT2 interests related to a Class of Subordinate Certificates, treating each Class LT1 interest as capped at zero or reduced by a fixed percentage of 100% of the interest accruing on such class.  Principal Relocation Payments shall be made from principal received on the Mortgage Loans from the related Collateral Group or Groups and shall also consist of a proportionate allocation of Realized Losses from the Mortgage Loans of the related Collateral Group or Groups.  For purposes of making Principal Relocation Payments, to the extent that the principal received during the Collection Period from the related Collateral Group and Realized Losses are insufficient to make the necessary reduction of principal, then interest shall accrue on the LT3 interest related to a Collateral Group or Groups (and be added to their principal balances) that are not receiving a Principal Relocation Payment to allow the necessary Principal Relocation Payment to be made.

If a Cross-Over Situation exists, the outstanding aggregate principal balance of the related LT1 and LT2 interests shall not be reduced below one percent of the aggregate Group Balance of the related Collateral Group or Groups as of the end of any Collection Period in excess of the Senior Certificates related to such Collateral Group as of the related Distribution Date (after taking into account distributions of principal and allocations of Realized Losses on such Distribution Date).  To the extent this limitation prevents the distribution of principal to the LT1 and LT2 interests of a Collateral Group and the related LT3 interest has already been reduced to zero, such excess principal from the other Collateral Group or Collateral Groups shall be paid proportionately to the LT3 interests of the Collateral Group or Groups whose aggregate LT1 and LT2 interests are less than one percent of the Group Subordinate Amount.  Any such shortfall as a result of the Collateral Group or Groups receiving the extra payment having a Ratio-strip Rate (as defined below) lower than the weighted average Ratio-strip Rate of the Collateral Group from which the payment was relocated shall be treated as a Realized Loss and if excess arises as result of the Collateral Group receiving the extra payment having a Ratio-strip Rate higher than the Collateral Group from which the payment was relocated it shall reimburse the Middle REMIC for prior Realized Losses.  The “Ratio-strip Rate” for each Collateral Group shall be equal to 5.750% for Collateral Group 1, 7.000% for Collateral Group 2, 6.250% for Collateral Group 3, and 5.750% for Collateral Group 4.  

The Class 15-PO Interest shall be entitled to receive the PO Principal Distribution Amount for Collateral Group 4 and the Class 30-PO Interest shall be entitled to receive the PO Principal Distribution Amount for Collateral Groups 1 and 3.

Section 1.02

Certain Calculations.  

Unless otherwise specified herein, for purposes of determining amounts with respect to the Certificates and the rights and obligations of the parties hereto, all calculations of interest (other than as provided in the Mortgage Loan documents) provided for herein shall be made on the basis of a 360-day year consisting of twelve 30 day months.

Section 1.03

Calculation of Applicable Fractions.

For purposes of determining Collateral Group 1 and Collateral Group 2, each Pool 1 Mortgage Loan shall be deemed to be allocated, based on the Net Mortgage Rate of such Mortgage Loan, as of the Cut off Date, either to Collateral Group 1 or Collateral Group 2 only, or between both Collateral Group 1 and Collateral Group 2, based on a fixed fraction that differs among Mortgage Loans (in each case, the “Applicable Fraction”), such that the principal of and interest on such Pool 1 Mortgage Loan is treated as if that Mortgage Loan were two loans bearing interest at two different effective Net Mortgage Rates, one higher than and one lower than the original Net Mortgage Rate of such Mortgage Loan.  The allocation of a Pool 1 Mortgage Loan to Collateral Group 1 or Collateral Group 2 shall not change based on a modification to the Net Mortgage Rate of such Mortgage Loan subsequent to the Cut-off Date.  The Applicable Fractions are calculated as follows:

(a)

Pool 1 Mortgage Loans with Net Mortgage Rates Less Than or Equal To 5.750%:  Each Pool 1 Mortgage Loan having a Net Mortgage Rate less than 5.750% shall be allocated to Collateral Group 1.

(b)

Pool 1 Loans with Net Mortgage Rates Greater Than 5.750% but less than 7.000%:  Each Pool 1 Mortgage Loan having a Net Mortgage Rate greater than 5.750%  but less than 7.000% shall be allocated between Collateral Group 1 and Collateral Group 2 by multiplying the Scheduled Principal Balance of such Pool 1 Mortgage Loan by its Applicable Fraction.  The Applicable Fraction for the portion of each such Pool 1 Mortgage Loan allocated to Collateral Group 1 is the quotient of (a)(i) 7.000% minus (ii) the related Net Mortgage Rate divided by (b) 1.250%.  The Applicable Fraction for the portion of each such Pool 1 Mortgage Loan allocated to Collateral Group 2 is (I) 1 minus (II) the quotient of (a)(i) 7.000% minus (ii) the related Net Mortgage Rate divided by (b) 1.250%.

(c)

Pool 1 Loans with Net Mortgage Rates Equal to or Greater Than 7.000%:  Each Pool 1 Mortgage Loan having a Net Mortgage Rate equal to or greater than 7.000% shall be allocated to Collateral Group 2.

The Depositor, concurrently with the execution and delivery hereof, hereby sells, transfers, assigns, sets over and otherwise conveys to the Trustee for the benefit of the Certificateholders, without recourse, all the right, title and interest of the Depositor in and to the Trust Fund.

the original or copies of each assumption, modification, written assurance or substitution agreement, if any; and

(E)

except as provided below, the original or duplicate original lender’s title policy and all riders thereto.

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

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

As promptly as practicable subsequent to such transfer and assignment, set forth in clause (a) above and in any event, within ninety (90) days thereafter, the Custodian shall affix the Trustee’s name to each assignment of Mortgage, as the assignee thereof, and, subject to Section 2.02, the Master Servicer shall enforce the obligations of the related Servicer pursuant to the related Servicing Agreement to (i) cause such assignment to be in proper form for recording in the appropriate public office for real property records and (ii) cause to be delivered for recording in the appropriate public office for real property records the assignments of the Mortgages to the Trustee, except that, with respect to any assignments of Mortgage as to which the related Servicer has not received the information required to prepare such assignment in recordable form, the related Servicer’s obligation to do so and to deliver the same for such recording shall be as soon as practicable after receipt of such information and in any event within ninety (90) days after receipt thereof and except that the related Servicer need not cause to be recorded any assignment which relates to a Mortgage Loan (a) in any state where, in an Opinion of Counsel addressed to the Trustee, such recording is not required to protect the Trustee’s interests in the Mortgage Loan against the claim of any subsequent transferee or any successor to or creditor of the Depositor or the Transferor, (b) in any state where recordation is not required by either Rating Agency to obtain the initial ratings on the Certificates set forth in the Prospectus Supplement or (c) with respect to any Mortgage which has been recorded in the name of MERS, or its designee.  As of the date hereof, recordation is not required in any state by either Rating Agency to obtain the initial rating on the Certificates (upon which statement the Master Servicer, the Trustee and the Custodian may each 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 Master Servicer 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 “Issuing Entity”) to be known, for convenience, as “MASTR Asset Securitization Trust 2006-1” 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.  If at any time either the Collection Account or the Distribution Account ceases to be an Eligible Account, the Master Servicer or the Trust Administrator, as applicable, shall immediately establish and maintain a new Collection Account or Distribution Account, as applicable, that is an Eligible Account, and shall immediately transfer all funds on deposit in the former Collection Account or Distribution Account, as applicable, to the new Collection Account or Distribution Account, as applicable.

(f)

It is agreed and understood by the Trustee, the Trust Administrator, the Depositor and the Transferor that it is not intended that any mortgage loan be included in the Trust that is a “High-Cost Home Loan” as defined in the New Jersey Home Ownership Act, effective as of November 27, 2003, or The Home Loan Protection Act of New Mexico, effective as of January 1, 2004, or that is a “High Cost Home Mortgage Loan” as defined in the Massachusetts Predatory Home Loan Practices Act, effective as of November 7, 2004, or that is an “Indiana High Cost Home Mortgage Loan” as defined in the Indiana High Cost Home Loan Act, effective as of January 1, 2005.

(g)

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 Class 1-A-13 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.  The Depositor represents that the representations to be made by the Trust Administrator on behalf of the Trust in the Cap Contract are true and correct.

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 not be under any duty or obligation to (i) inspect, review or examine said documents, instruments, certificates or other papers to determine that the same are genuine, enforceable or appropriate for the represented purpose or that they have actually been recorded in the real estate records or that they are other than what they purport to be on their face or (ii) determine whether the Mortgage File should include any of the documents specified in Section 2.01(b)(i)(D) with respect to each Mortgage Loan that is not a Cooperative Loan and Section 2.01(b)(ii)(H) with respect to each Cooperative 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 Loan and Section 2.01(b)(ii)(H) with respect to each Cooperative 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 from the Trustee, 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.  Any such purchase of a Mortgage Loan shall not be effected prior to the delivery to the Custodian of a Request for Release substantially in the form of Exhibit M.  The Purchase Price for any such 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 Mortgage Loan released pursuant hereto.  The Transferor shall promptly reimburse the Master Servicer and the Trustee for any expenses reasonably incurred by the Master Servicer or the Trustee in respect of enforcing such repurchase by the Transferor.

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

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

Section 2.03

Remedies for Breaches of Representations and Warranties.  

The Transferor hereby makes the representations and warranties set forth in Schedule II hereto, and by this reference incorporated herein, to the Depositor and the Trustee, as of the Closing Date, or if so specified therein, as of the Cut-off Date.  With respect to any of the representations 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 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 applicable 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.  A breach which causes a Mortgage Loan not to constitute a “qualified mortgage” within the meaning of Section 860G(a)(3) of the Code, 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 Mortgage Loan (a “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 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 and the Trustee for any expenses reasonably incurred by the Master Servicer or the Trustee in respect of enforcing the remedies for such breach by the Transferor.

With respect to any Eligible Substitute Mortgage Loan or 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 shall release the Mortgage File held for the benefit of the Certificateholders relating to such Deleted Mortgage Loan to the Transferor and shall execute and deliver or cause the Trustee to execute and deliver at the Transferor’s direction such instruments of transfer or assignment prepared by the Transferor, without recourse, representation or warranty, as shall be necessary to vest title in the Transferor, as applicable, or its designee, the Trustee’s interest in any Deleted Mortgage Loan substituted for pursuant to this Section 2.03.

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

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

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

The Depositor hereby represents and warrants to the Trustee, the Trust Administrator 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 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.

ARTICLE III

ADMINISTRATION AND MASTER

SERVICING OF MORTGAGE LOANS

Section 3.01

Master Servicing of Mortgage Loans.  

For and on behalf of the Certificateholders, the Master Servicer shall supervise, monitor and oversee the obligation of the Servicers to service and administer their respective Mortgage Loans in accordance with the terms of the applicable Servicing Agreement and shall have full power and authority to do any and all things which it may deem necessary or desirable in connection with such master servicing and administration.  In performing its obligations hereunder, the Master Servicer shall act in a manner consistent with this Agreement, subject to the prior two sentences, 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.

Section 3.02

Monitoring of Servicers.  

(a)

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

(b)

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

(c)

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

(d)

The Master Servicer shall require each Servicer to comply with the remittance requirements and other obligations set forth in the related Servicing Agreement.

(e)

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

(f)

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

(g)

To the extent a Servicer 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.

(h)

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

Section 3.05

Trustee to Act as Master Servicer.  

In the event that the Master Servicer shall for any reason no longer be the Master Servicer hereunder (including by reason of a Master Servicer Event of Termination), the Trustee or its successor shall in accordance with Section 7.02 thereupon assume all of the rights and obligations of the Master Servicer hereunder arising thereafter (except that the Trustee shall not be (i) liable for losses of the predecessor Master Servicer pursuant to Section 3.09 hereof or any acts or omissions of the predecessor Master Servicer hereunder), (ii) obligated to make Advances if it is prohibited from doing so by applicable law, (iii) obligated to effectuate repurchases or substitutions of Mortgage Loans hereunder including, but not limited to, repurchases or substitutions of Mortgage Loans pursuant to Section 2.02 or 2.03 hereof, (iv) responsible for expenses of the Master Servicer pursuant to Section 2.03 hereof, (v) deemed to have made any representations and warranties of the Master Servicer pursuant to Section 2.09 hereunder) or (vi) obligated to perform any obligation of the Master Servicer under Section 3.21, 3.22 or 9.12 with respect to any periods during which the Trustee was not the Master Servicer ).  Any such assumption shall be subject to Section 7.02 hereof.  If the Master Servicer shall for any reason no longer be the Master Servicer (including by reason of any Master Servicer Event of Termination), the Trustee or its successor may, but shall not be obligated to, succeed to any rights and obligations of the Master Servicer under each subservicing agreement.

The Master Servicer shall, upon request of the Trustee, but at the expense of the Master Servicer, deliver to the assuming party all documents and records relating to each subservicing agreement or substitute subservicing agreement and the Mortgage Loans then being serviced thereunder and an accounting of amounts collected or held by it and otherwise use its best efforts to effect the orderly and efficient transfer of each subservicing agreement or substitute subservicing agreement to the assuming party.

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 Master Servicer, including, without limitation, any costs or expenses 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 such reimbursement from amounts on deposit in the Distribution Account pursuant to Section 3.10(b)(iv); provided that the Master Servicer shall reimburse the Trust for any such expense incurred by the Trust.

Section 3.06

Protected Accounts.

The Master Servicer shall enforce the obligation of each Servicer to establish and maintain a Protected Account in accordance with the applicable Servicing Agreement, with records to be kept with respect thereto on a Mortgage Loan by Mortgage Loan basis, into which accounts shall be deposited within 48 hours (or as of such other time specified in the related Servicing Agreement) of receipt all collections of principal and interest on any Mortgage Loan or amounts received with respect to any REO Property, including Principal Prepayments, Insurance Proceeds, Liquidation Proceeds, and advances made from the Servicer’s own funds (less servicing compensation as permitted by the applicable Servicing Agreement in the case of any Servicer) and all other amounts to be deposited in the Protected Account.  The Master Servicer is hereby authorized to make withdrawals from and deposits to the related Protected Account for purposes required or permitted by this Agreement.  Permitted Investments of funds in Protected Accounts must mature at least one Business Day before the subsequent Distribution Date.

The related Servicer (to the extent provided in the Servicing Agreement) shall deposit the amount of any such loss in the Protected Account within two Business Days of receipt of notification of such loss but not later than the second Business Day prior to the Distribution Date on which the moneys so invested are required to be distributed to the Certificateholders.

Pursuant to Sections 3.07 and 3.08, any amounts collected by the Master Servicer, or by any Servicer, under any insurance policies (other than amounts to be applied to the restoration or repair of the property subject to the related Mortgage or released to the Mortgagor in accordance with the applicable Servicing Agreement) shall be deposited into the Collection Account, subject to withdrawal pursuant to Sections 3.07 and 3.08.

The Master Servicer shall not take, or permit any Servicer (to the extent such action is prohibited under the applicable Servicing Agreement) to take, any action that would result in noncoverage under any applicable Primary Insurance Policy of any loss which, but for the actions of such Master Servicer or Servicer, would have been covered thereunder.  The Master Servicer shall use its best reasonable efforts to cause each Servicer (to the extent required under the related Servicing Agreement) to keep in force and effect (to the extent that the Mortgage Loan requires the Mortgagor to maintain such insurance), primary mortgage insurance applicable to each Mortgage Loan in accordance with the provisions of this Agreement and the related Servicing Agreement, as applicable.  The Master Servicer shall not, and shall not permit any Servicer (to the extent required under the related Servicing Agreement) to, cancel or refuse to renew any such Primary Insurance Policy that is in effect at the date of the initial issuance of the Mortgage Note and is required to be kept in force hereunder except in accordance with the provisions of this Agreement and the related Servicing Agreement, as applicable.

Section 3.15

REO Property.  

(a)

In the event the Trust Fund acquires ownership of any REO Property in respect of any related Mortgage Loan, the deed or certificate of sale shall be issued to the Trustee, or to its nominee, on behalf of the related Certificateholders.  The Master Servicer shall, to the extent provided in the applicable Servicing Agreement, cause the applicable Servicer to sell any REO Property as expeditiously as possible and in accordance with the provisions of this Agreement and the related Servicing Agreement, as applicable.  Pursuant to its efforts to sell such REO Property, the Master Servicer shall cause the applicable Servicer to protect and conserve such REO Property in the manner and to the extent required by the applicable Servicing Agreement, subject to the REMIC Provisions.

(b)

The Master Servicer shall, to the extent required by the related Servicing Agreement, cause the applicable Servicer to deposit all funds collected and received in connection with the operation of any REO Property in the Protected Account.

(d)

The Liquidation Proceeds from the final disposition of the REO Property, net of any payment to the Master Servicer and the applicable Servicer as provided above shall be deposited in the Protected Account on or prior to the Determination Date in the month following receipt thereof and be remitted by wire transfer in immediately available funds to the Master Servicer for deposit into the Collection Account.

In the event that the Trust Fund acquires any Mortgaged Property as aforesaid or otherwise in connection with a default or imminent default on a Mortgage Loan, the Master Servicer shall enforce the obligation of the related Servicer to dispose of such Mortgaged Property prior to the close of the third calendar year after the year in which the Trust Fund acquires such Mortgaged Property unless the Servicer shall have applied for and received an extension of such period from the Internal Revenue Service, in which case the Trust Fund may continue to hold such Mortgaged Property for the period of such extension.  Notwithstanding any other provision of this Agreement, no Mortgaged Property acquired by the Trust Fund shall be rented (or allowed to continue to be rented) or otherwise used for the production of income by or on behalf of the Trust Fund in such a manner or pursuant to any terms that would (i) cause such Mortgaged Property to fail to qualify as “foreclosure property” within the meaning of Section 860G(a)(8) of the Code or (ii) subject any REMIC hereunder to the imposition of any federal, state or local income taxes on the income earned from such Mortgaged Property under Section 860G(c) of the Code or otherwise, unless the Master Servicer or related Servicer, as applicable, has agreed to indemnify and hold harmless the Trust Fund with respect to the imposition of any such taxes.

In the event of a default on a Mortgage Loan one or more of whose obligor is not a United States Person, as that term is defined in Section 7701(a)(30) of the Code, in connection with any foreclosure or acquisition of a deed in lieu of foreclosure (together, “foreclosure”) in respect of such Mortgage Loan, the Master Servicer will cause the applicable Servicer to comply with the provisions of Treasury Regulation Section 1.1445-2(d)(3) (or any successor thereto) necessary to assure that no withholding tax obligation arises with respect to the proceeds of such foreclosure except to the extent, if any, that proceeds of such foreclosure are required to be remitted to the obligors on such Mortgage Loan.

Section 3.16

Due-on-Sale Clauses; Assumption Agreements.  

To the extent provided in the applicable Servicing Agreement, to the extent Mortgage Loans contain enforceable due on sale clauses, the Master Servicer shall cause the Servicers to enforce such clauses in accordance with the applicable Servicing Agreement.  If applicable law prohibits the enforcement of a due-on-sale clause or such clause is otherwise not enforced in accordance with the applicable Servicing Agreement, and, as a consequence, a Mortgage Loan is assumed, the original Mortgagor may be released from liability in accordance with the applicable Servicing Agreement.

Section 3.17

Trustee to Cooperate; Release of Mortgage Files.  

Upon (i) the payment in full of any Mortgage Loan, or the receipt by the Master Servicer of a notification that payment in full will be escrowed in a manner customary for such purposes or (ii) otherwise in connection with the servicing of any Mortgage Loan, the Master Servicer shall, upon receipt of notification from the related Servicer pursuant to the applicable Servicing Agreement which notification shall state that such payment in full has been deposited in the Collection Account or has otherwise been escrowed in a manner customary for such purposes, instruct the Custodian to, and the Custodian shall, release the related Mortgage File to the related Servicer.  Upon notification, the Trustee shall at the Custodian’s direction execute and deliver to the Custodian the request for reconveyance, deed of reconveyance or release or satisfaction of mortgage or such instrument releasing the lien of the Mortgage in each case provided by the Custodian, together with the Mortgage Note with written evidence of cancellation thereon.  Expenses incurred in connection with any instrument of satisfaction or deed of reconveyance shall be chargeable to the related Mortgagor.

If the Master Servicer or any related Servicer at any time seeks to initiate a foreclosure proceeding in respect of any Mortgaged Property as authorized by this Agreement or the Servicing Agreement, the Master Servicer or any related Servicer shall deliver or cause to be delivered to the Trustee, for signature, as appropriate, any court pleadings, requests for trustee’s sale or other documents necessary to effectuate such foreclosure or any legal action brought to obtain judgment against the Mortgagor on the Mortgage Note or the Mortgage or to obtain a deficiency judgment or to enforce any other remedies or rights provided by the Mortgage Note or the Mortgage or otherwise available at law or in equity.

Subject to this Section 3.17, the Trustee shall execute, at the written request of the Master Servicer, and furnish to the Master Servicer and any Servicer such documents as are necessary or appropriate to enable the Master Servicer or any Servicer to carry out their servicing and administrative duties hereunder.  The Trustee shall not be liable for the actions of the Master Servicer or any Servicers under such powers of attorney.

All Mortgage Files and funds collected or held by, or under the control of, the Master Servicer, the related Servicer or the Custodian in respect of any Mortgage Loans, whether from the collection of principal and interest payments or from Liquidation Proceeds, including but not limited to, any funds on deposit in the Collection Account or any Protected Account, shall be held by the Master Servicer, the related Servicer or the Custodian for and on behalf of the Trustee and shall be and remain the sole and exclusive property of the Trust, subject to the applicable provisions of this Agreement and the related Servicing Agreement.  Each of the Master Servicer and the Custodian also agrees that it shall not create, incur or subject any Mortgage File or any funds that are deposited in the Collection Account, Distribution Account or any Escrow Account, or any funds that otherwise are or may become due or payable to the Trustee for the benefit of the Certificateholders, to any claim, lien, security interest, judgment, levy, writ of attachment or other encumbrance, or assert by legal action or otherwise any claim or right of setoff against any Mortgage File or any funds collected on, or in connection with, a Mortgage Loan, except, however, that the Master Servicer shall be entitled to set off against and deduct from any such funds any amounts that are properly due and payable to the Master Servicer under this Agreement.

Such access shall be afforded without charge, but only upon reasonable and prior written request and during normal business hours at the offices designated by the Master Servicer, the Custodian and the related Servicer.  Nothing in this Section shall limit the obligation of the Master Servicer, the Custodian and the related Servicer to observe any applicable law prohibiting disclosure of information regarding the Mortgagors and the failure of the Master Servicer, the Custodian or the related Servicer to provide access as provided in this Section as a result of such obligation shall not constitute a breach of this Agreement.  In fulfilling such requests, the Master Servicer and the Custodian shall not be responsible to determine the sufficiency of such information.

(ii)

Prior to the Cross-Over Date, to the extent any PO Deferred Amount has not been paid from Available Funds for any Collateral Group, the available Subordinate Principal Distribution Amount for the Subordinate Certificates shall be applied to pay any such PO Deferred Amount.  

(iii)

If on any Distribution Date, one or more of Certificate Groups is an Undercollateralized Group, the available Subordinate Principal Distribution Amount for the Subordinate Certificates shall be paid to such Undercollateralized Group or Groups as principal to the Senior Certificates of such Undercollateralized Group or Groups in accordance with the priorities set forth in Section 4.02(a)(i) until the aggregate Class Principal Balance of the Senior Certificates of each such Undercollateralized Group equals the related Group Balance of the related Collateral Group (net of the applicable PO Percentage of the Scheduled Principal Balance of each Discount Mortgage Loan in such Collateral Group, if any). If more than one of such Certificate Groups is an Undercollateralized Group, the available Subordinate Principal Distribution Amount for the Subordinate Certificates shall be distributed between such Undercollateralized Groups pro rata according to Group Balances.

(iv)

On or after the date on which the Class Principal Balances of all of the Senior Certificates in any Certificate Group have been reduced to zero, amounts otherwise distributable as principal on the Subordinate Certificates, up to the applicable Apportioned Subordinate Principal Distribution Amount, shall be paid pro rata as principal to the remaining Senior Certificates of such other Certificate Group or Groups in accordance with the priorities set forth in Section 4.02(a)(i), provided that on such Distribution Date (a) the Aggregate Subordinate Percentage for the Subordinate Certificates for such Distribution Date is less than twice the initial Aggregate Subordinate Percentage for the Subordinate Certificates or (b) the average outstanding principal balance of the Mortgage Loans delinquent 60 days or more over the last six months (including delinquent Mortgage Loans in bankruptcy, and all Mortgage Loans in foreclosure and REO Properties) as a percentage of the Group Subordinate Amount is greater than or equal to 50%.

(ii)

the applicable Non-PO Percentage (with respect to Collateral Group 1 and Collateral Group 2, multiplied by the related Applicable Fraction) of any Realized Loss with respect to any Mortgage Loan (other than an Excess Loss) shall be allocated first to the Subordinate Certificates in reverse order of their respective numerical Class designations (beginning with the Class of Subordinate Certificates then outstanding with the highest numerical Class designation) until the respective Class Principal Balance of each such Class is reduced to zero, and second to the Senior Certificates (or in the case of the Class 1-A-5 Certificates, the Components thereof) of the related Certificate Group (not including the related Interest Only and the Class PO Certificates) pro rata based upon their respective Class Principal Balances (or, with respect to the Components, their respective aggregate Certificate Principal Balances) after giving effect to distributions of principal on such Distribution Date until the Class Principal Balance of each such Class has been reduced to zero or the aggregate Certificate Principal Balance of each such Component has been reduced to zero, as applicable; provided, however, that (A) the losses allocable to the Class 1-A-1 Certificates, under this paragraph, will instead be allocated to Component 1-A-5-1 until the Certificate Principal Balance of Component 1-A-5-1 has been reduced to zero, (B) the losses allocable to the Class 1-A-3 Certificates, under this paragraph, will instead be allocated to Component 1-A-5-2 until the Certificate Principal Balance of Component 1-A-5-2 has been reduced to zero, (C) the losses allocable to the Class 1-A-4 Certificates, under this paragraph, will instead be allocated to Component 1-A-5-3 until the Certificate Principal Balance of Component 1-A-5-3 has been reduced to zero, (D) the losses allocable to the Class 1-A-2 Certificates, under this paragraph, will instead be allocated to the Class 1-A-14 Certificates until the Certificate Principal Balance of the Class 1-A-14 Certificates has been reduced to zero, (E) the losses allocable to the Class 1-A-6 Certificates, under this paragraph, will instead be allocated to the Class 1-A-7 Certificates until the Certificate Principal Balance of the Class 1-A-7 Certificates has been reduced to zero, (F) the losses allocable to the Class 1-A-11 Certificates, under this paragraph, will instead be allocated to the Class 1-A-12 Certificates until the Certificate Principal Balance of the Class 1-A-12 Certificates has been reduced to zero, and (G) the losses allocable to the Class 3-A-1 Certificates, under this paragraph, will instead be allocated to the Class 3-A-2 Certificates until the Certificate Principal Balance of the Class 3-A-2 Certificates has been reduced to zero; provided, further, that any Realized Loss allocated to the Class 1-A-5 Certificates, other than in accordance with the preceding proviso, will be allocated between Component 1-A-5-1, Component 1-A-5-2 and Component 1-A-5-3, pro rata, based on their outstanding Certificate Principal Balances; and

(iii)

the applicable Non-PO Percentage (and with respect to Collateral Group 1 and Collateral Group 2, multiplied by the related Applicable Fraction) of any Excess Losses occurring on any Mortgage Loan in any Collateral Group shall be allocated among (A) (1) the Group 1 Certificates, in the case of an Excess Loss on a Group 1 Mortgage Loan, (2) the Group 2 Certificates, in the case of an Excess Loss on a Group 2 Mortgage Loan, (3) the Group 3 Certificates, in the case of an Excess Loss on a Group 3 Mortgage Loan and (4) the Group 4 Certificates, in the case of an Excess Loss on a Group 4 Mortgage Loan (other than, in each case, the related Interest Only Certificates of such Certificate Group and the related Class of Class PO Certificates); and (B) each Class of Subordinate Certificates, pro rata based upon their respective Class Principal Balances after giving effect to distributions of principal on such Distribution Date (except, in the case of the Subordinate Certificates, based on their pro-rata portion of the Group Subordinate Amount for the Collateral Group which incurred the Excess Loss (based on their respective Class Principal Balances)); and

(b)

The Class Principal Balance of the Class of Subordinate Certificates then outstanding with the highest numerical Class designation shall be reduced on each Distribution Date by the sum of (i) the amount of any payments on the Class 15-PO in respect of any PO Deferred Amounts for Collateral Group 4, and the amount of any payments on the Class 30-PO Certificates in respect of any PO Deferred Amounts for Collateral Group 1 and Collateral Group 3 pursuant to Section 4.02(a) priority third, sub-clause (ii) and (ii) the amount, if any, by which the aggregate of the Class Principal Balances of all outstanding Classes of Group 1, Group 2, Group 3 and Group 4 Certificates (other than the Interest Only and Class PO Certificates) and Subordinate Certificates (after giving effect to the distribution of principal and the allocation of Realized Losses with respect to the Mortgage Loans) exceeds the Aggregate Pool Principal Balance for the following Distribution Date, less any Deficient Valuations occurring before the Bankruptcy Loss Coverage Amount has been reduced to zero and less the PO Percentage of any Discount Mortgage Loans; and

(c)

Any allocation of Realized Losses to a Certificate or a Component or any reduction in the Certificate Principal Balance of a Certificate or a Component pursuant to Section 4.03(a) or (b) above shall be accomplished by reducing the Certificate Principal Balance of such Certificate or Component immediately following the distributions made on the related Distribution Date in accordance with the definition of “Certificate Principal Balance” herein; provided that no Realized Loss with respect to any Collateral Group shall be allocated to reduce the Certificate Principal Balance of a Senior Certificate or a Component in any Certificate Group (other than the related Class PO Certificates) to the extent that such allocation would reduce the aggregate Certificate Principal Balance of all of the Senior Certificates (other than the Interest Only and Class PO Certificates) and Subordinate Certificates to an amount less than the Aggregate Pool Principal Balance for the following Distribution Date minus any related Deficient Valuations occurring before the Bankruptcy Loss Coverage Termination Date and minus the PO Percentage of any Discount Mortgage Loans (such limitation, the “Loss Allocation Limitation”).

(i)

first, up to the amount of the Non-PO Recoveries with respect to any Collateral Group, the Class Principal Balance of each Class of Senior Certificates (other than the Class PO Certificates and Interest Only Certificates and the Class 1-A-5 Certificates) and the aggregate Certificate Principal Balance of each Component in the Certificate Group corresponding to such Collateral Group will be increased, pro rata, up to the amount of the excess, if any, of (x) unrecovered Realized Losses previously allocated to each such Class or Component, if any over (y) amounts previously applied to the increase of the Class Principal Balance of such Class or aggregate Certificate Principal Balance of such Component pursuant to this Section 4.03(d)(i); and

(ii)

second, up to the amount of the Non-PO Recoveries related to each Collateral Group remaining after allocation pursuant to the preceding clause (i), the Class Principal Balance of each Class of Subordinate Certificates, in order of seniority, will be increased, by the amount of the excess, if any, of (x) unrecovered Realized Losses previously allocated to each such Class, if any, over (y) amounts previously applied to the increase of the Class Principal Balance of such Class pursuant to this Section 4.03(d)(ii)(A).

(e)

With respect to any Distribution Date on or after the Cross-Over Date, the Trust Administrator shall distribute the amount of any Recovery on a Mortgage Loan received during the calendar month prior to that Distribution Date as follows:

(i)

(A) to the Class 15-PO Certificates, the PO Percentage, multiplied by the related Applicable Fraction, of any Recovery on any Mortgage Loan in Collateral Group 4 and (B) to the Class 30-PO Certificates, the PO Percentage, multiplied by the related Applicable Fraction, of any Recovery on any Mortgage Loan in Collateral Group 1 and Collateral Group 3; and

Assistance in using the internet website can be obtained by calling the Trust Administrator’s customer service desk at (301) 815-6600.  Parties that are unable to use the above distribution method are entitled to have a paper copy mailed to them via first class mail by calling the customer service desk and indicating such.  The Trust Administrator shall have the right to change the way the Distribution Date Statement is distributed in order to make such distribution more convenient and/or more accessible and the Trust Administrator shall provide timely and adequate notification to the Certificateholders and the parties to this Agreement regarding any such changes.

The Trust Administrator shall also be entitled to rely on but shall not be responsible for the content or accuracy of any information provided by third parties (including the Servicers) for purposes of preparing the Distribution Date Statement and may affix thereto any disclaimer it deems appropriate in its reasonable discretion (without suggesting liability on the part of any other party hereto).

As a condition to access the Trust Administrator’s internet website, the Trust Administrator may require registration and the acceptance of a disclaimer.  The Trust Administrator will not be liable for the dissemination of information in accordance with this Agreement.

(c)

Within a reasonable period of time after the end of each calendar year, the Trust Administrator shall cause to be furnished upon request to each Person who at any time during the calendar year was a Certificateholder, a statement containing the information set forth in clauses (a)(i), (a)(ii) and (a)(vii) of this Section 4.04 aggregated for such calendar year or applicable portion thereof during which such Person was a Certificateholder.  Such obligation of the Trust Administrator shall be deemed to have been satisfied to the extent that substantially comparable information shall be provided by the Trust Administrator pursuant to any requirements of the Code as from time to time in effect.

Section 4.05

Determination of LIBOR.  

On each LIBOR Determination Date for a 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.  As used herein, “Telerate page 3750” means the display designated as page 3750 on the Bridge Telerate Service.  The “Interest Settlement Rates” currently are based on rates quoted by 16 British Bankers’ Association designated banks as being in the view of such banks, the offered rate at which deposits are being quoted to prime banks in the London interbank market.  Such Interest Settlement Rates are calculated by eliminating the four highest rates and the four lowest rates, averaging the eight remaining rates, carrying the result (expressed as a percentage) out to six decimal places, and rounding to five decimal places.

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

If on any LIBOR Determination Date for a 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 next Interest Accrual Period will be LIBOR as determined on the previous LIBOR Determination Date for such Class of LIBOR Certificates, or, in the case of the first LIBOR Determination Date, the Initial LIBOR Rate.

The establishment of LIBOR on the LIBOR Determination Date by the Trust Administrator and the Trust Administrator’s calculation of the rates of interest applicable to each of the LIBOR Certificates for the related Interest Accrual Period shall, 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 Interest Accrual Period to Certificate Owners or Holders of LIBOR Certificates who place a telephone call to the Trust Administrator at (301) 815-6600 and make a request therefor.

Section 4.06

Cap Payments.

On each Distribution Date, the Trust Administrator shall withdraw the Cap Payment from funds on deposit in the Cap Reserve Fund and shall distribute such amount to the Class 1-A-13 Certificates as interest on such Class.

ARTICLE V

THE CERTIFICATES

Section 5.01

The Certificates.  

The Certificates shall be substantially in the forms attached hereto as Exhibit 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 Certificates shall be dated the date of their countersignature.  On the Closing Date, the Trust Administrator shall countersign the Certificates to be issued at the direction of the Depositor, or any affiliate thereof.

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

Section 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)

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 forms set forth in Exhibit J (the “Transferor Certificate”).  Further, such Certificateholder’s prospective transferee will either (i) deliver a letter in substantially the form of either Exhibit K (the “Investment Letter”) or Exhibit L (the “Rule 144A Letter”) or (ii) deliver to the Trust Administrator at the expense of the transferor an Opinion of Counsel that such transfer may be made pursuant to an exemption from the Securities Act.  The Depositor shall provide to any Holder of a Private Certificate and any prospective transferee designated by any such Holder, information regarding the related Certificates and the Mortgage Loans and such other information as shall be necessary to satisfy the condition to eligibility set forth in Rule 144A(d)(4) for transfer of any such Certificate without registration thereof under the Securities Act pursuant to the registration exemption provided by Rule 144A.  The Trust Administrator and the Master Servicer shall cooperate with the Depositor, in accordance with the Depositor’s request, in providing the Rule 144A information referenced in the preceding sentence, including providing to the Depositor, to the extent in its possession, such information regarding the Certificates, the Mortgage Loans and other matters regarding the Trust Fund as the Depositor shall reasonably request to meet its obligation under the preceding sentence.  Each Holder of a Private Certificate desiring to effect such transfer shall, and does hereby agree to, indemnify the Trustee, the Trust Administrator, the 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.

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 company which is purchasing such Certificates with funds contained in an “insurance company general account” (as such term is defined in Section V(e) of Prohibited Transaction Class Exemption 95-60 (“PTCE 95-60”)) and that the purchase and holding of such Certificates are covered under Sections I and III of PTCE 95-60 or (iii) an Opinion of Counsel satisfactory to the Trust Administrator, which Opinion of Counsel shall not be an expense of the Trustee, the Trust Administrator, the Depositor, the Transferor, the Master Servicer or the Trust Fund, addressed to the Trust Administrator to the effect that the purchase or holding of such ERISA-Restricted Certificate will not result in non-exempt prohibited transactions under Section 406 of ERISA and/or Section 4975 of the Code and will not subject the Trustee, the Trust Administrator, the Depositor, the Transferor or the Master Servicer to any obligation in addition to those expressly undertaken in this Agreement.  For purposes of the preceding sentence, with respect to an ERISA-Restricted Certificate that is not a Private Certificate or a Residual Certificate, in the event the representation letter referred to in the preceding sentence is not so furnished, such representation shall be deemed to have been made to the Trust Administrator by the transferee’s (including an initial acquirer’s) acceptance of the ERISA-Restricted Certificates.  Notwithstanding anything else to the contrary herein, any purported transfer of an ERISA-Restricted Certificate, to or on behalf of 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.

(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 provisions of this Agreement so long as the Transfer was registered after receipt of the related Transfer Affidavit, Transferor Certificate and either the Rule 144A Letter or the Investment Letter.  The Trust Administrator shall be entitled but not obligated to recover from any Holder of a Residual Certificate that was in fact not a Permitted Transferee at the time it became a Holder or, at such subsequent time as it became other than a Permitted Transferee, all payments made on such Residual Certificate at and after either such time.  Any such payments so recovered by the Trust Administrator shall be paid and delivered by the Trust Administrator to the last preceding Permitted Transferee of such Certificate.

(v)

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

The restrictions on Transfers of a Residual Certificate set forth in this Section 5.02(c) shall cease to apply (and the applicable portions of the legend on a Residual Certificate may be deleted) with respect to Transfers occurring after delivery to the Trust Administrator of an Opinion of Counsel, which Opinion of Counsel shall not be an expense of the Trust Fund, the Trustee, the Trust Administrator, the Transferor or the Master Servicer, to the effect that the elimination of such restrictions will not cause any REMIC hereunder to fail to qualify as a REMIC at any time that the Certificates are outstanding or result in the imposition of any tax on the Trust Fund, a Certificateholder or another Person.  Each Person holding or acquiring any Ownership Interest in a Residual Certificate hereby consents to any amendment of this Agreement which, based on an Opinion of Counsel furnished 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 exercising the rights of Holders under this Agreement, and requests and directions for and votes of such representative shall not be deemed to be inconsistent if they are made with respect to different Certificate Owners; and (vi) the Trust Administrator may conclusively rely and shall be fully protected in relying upon information furnished by the Depository with respect to its Depository Participants and furnished by the Depository Participants with respect to indirect participating firms and persons shown on the books of such indirect participating firms as direct or indirect Certificate Owners.

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

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

Section 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 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 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 or the Trustee nor any agent of the Master Servicer, the Trust Administrator 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 held accountable by reason of the disclosure of any such information as to the list of the Certificateholders hereunder, regardless of the source from which such information was derived.

Section 5.06

Maintenance of Office or Agency.  

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

The Master Servicer shall not resign from the obligations and duties hereby imposed on it except (a) upon appointment of a successor master servicer and receipt by the Trustee of a letter from each Rating Agency that such a resignation and appointment will not result in a downgrading of the rating of any of the Certificates, or (b) upon determination that its duties hereunder are no longer permissible under applicable law, or (c) pursuant to Section 6.05.  Any such determination under clause (b) permitting the resignation of the Master Servicer shall be evidenced by an Opinion of Counsel to such effect delivered to the Trustee.

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

(iv)

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

(v)

The Master Servicer assigns or delegates its duties or rights under this Agreement in contravention of the provisions permitting such assignment or delegation under Section 6.04; or

(vi)

any failure by the Master Servicer to comply with Sections 3.21 or 3.22.

In each and every such case, so long as such Master Servicer Event of Termination with respect to the Master Servicer shall not have been remedied, the Trustee may, and (i) at the direction of the Holders of Certificates evidencing Voting Rights aggregating not less than 25% of the Certificates or (ii) if such Master Servicer Event of Termination is related to a failure by the Master Servicer to make any Advance required to be made by it pursuant to the terms of this Agreement, the Trustee shall, in each case by notice in writing to the Master Servicer, with a copy to the Rating Agencies, terminate all of the rights and obligations (but not the liabilities accruing prior to the date of termination) of the Master Servicer under this Agreement and in and to the Mortgage Loans and/or the REO Property serviced by the Master Servicer and the proceeds thereof; provided, however, with respect to an Event of Default set forth in clause (vi), the Depositor, at its sole option, but with the consent of the Trustee, may permit a cure period for the Master Servicer to deliver such Assessment of Compliance or Accountant’s Attestation, but in no event later than March 25 of such year.  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 otherwise, 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 this 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 4.01.  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 4.01 hereof or if it is otherwise unable to so act, or if it has been requested in writing by 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 as a result of such assignment and delegation.  Pending appointment of a successor to the Master Servicer hereunder, the Trustee, unless the Trustee is prohibited by law from so acting, shall, subject to Section 3.05 hereof, act in such capacity as hereinabove provided.  In connection with such appointment and assumption, the Trustee may make such arrangements for the compensation of such successor master servicer out of payments on Mortgage Loans as it and such successor master servicer shall agree; provided, however, that no such compensation shall be in excess of the compensation permitted the Master Servicer hereunder.  The Trustee and such successor master servicer shall take such action, consistent with this Agreement, as shall be necessary to effectuate any such succession.  Neither the Trustee nor any other successor master servicer shall be deemed to be in default hereunder by reason of any failure to make, or any delay in making, any distribution hereunder or any portion thereof or any failure to perform, or any delay in performing, any duties or responsibilities hereunder, in either case caused by the failure of the Master Servicer to deliver or provide, or any delay in delivering or providing, any cash, information, documents or records to it.

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

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

Section 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 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 all Certificateholders notice of each such Master Servicer Event of Termination hereunder actually known to a Responsible Officer of the Trustee or the Trust Administrator, unless such Master Servicer Event of Termination shall have been cured or waived.

ARTICLE VIII

CONCERNING THE TRUSTEE

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 Certificateholders of such non-conforming instrument in the event the Trustee, after so requesting, does not receive a satisfactorily corrected instrument.

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

(i)

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

(ii)

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

(iii)

the Trustee shall not be liable with respect to any action taken, suffered or omitted to be taken by it in good faith in accordance with the direction of 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; and

(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.

(ii)

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

(iii)

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

(iv)

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

(v)

the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys or the Custodian and the Trustee shall not be responsible for any misconduct or negligence on the part of any such agent, attorney or custodian appointed by the Trustee with due care;

(vi)

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

(vii)

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

(viii)

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

(ix)

the Trustee shall be under no obligation to exercise any of the trusts, rights or powers vested in it by this Agreement or to institute, conduct or defend any litigation hereunder or in relation hereto at the request, order or direction of any of the Certificateholders, pursuant to the provisions of this Agreement, unless such Certificateholders shall 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.

The Trustee and any director, officer, employee, agent or “control person” within the meaning of the Securities Act of 1933, as amended, and the Securities Exchange of 1934, as amended (“Control Person”), of the Trustee shall be indemnified by the Trust and held harmless against any loss, liability or expense (including reasonable attorney’s fees) (i) incurred in connection with any claim or legal action relating to (a) this Agreement, (b) the Mortgage Loans or (c) the Certificates, (ii) incurred in connection with the performance of any of the Trustee’s duties hereunder, other than any loss, liability or expense (x) incurred by reason of willful misfeasance, bad faith or negligence in the performance of any of the Trustee’s duties hereunder or (y) which would not constitute an “unanticipated expense incurred by the REMIC” within the meaning of Treasury Regulations Section 1.860G-1(b)(3)(ii) and (iii) incurred by reason of any action of the Trustee taken at the direction of the Certificateholders.  Such indemnity shall survive the termination of this Agreement or the resignation or removal of the Trustee hereunder.

Appointment of Co-Trustee or Separate Trustee.

If the Master Servicer 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 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:

(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 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.

The Trustee shall notify the Rating Agencies of any change of Trust Administrator.

Section 9.11

Tax Matters.  

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

(a)

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

(b)

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

(c)

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

(d)

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

(e)

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

(f)

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

(g)

not permit the creation of any interests in such REMIC other than as set forth in the Preliminary Statement;

(h)

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

(i)

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

(j)

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

(k)

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

(l)

pay, from the sources specified in the last paragraph of this Section 9.11, the amount of any federal or state tax, including prohibited transaction taxes as described below, imposed on such REMIC prior to its termination when and as the same shall be due and payable (but such obligation shall not prevent the Master Servicer or any other appropriate Person from contesting any such tax in appropriate proceedings and shall not prevent the Master Servicer from causing the withholding of payment of such tax, if permitted by law, pending the outcome of such proceedings);

(m)

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

(n)

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

The Holder of the largest Percentage Interest of the Class A-LR Certificates shall act as “tax matters person” within the meaning of Treasury Regulations Section 1.860F-4(d) for the Subsidiary REMIC and the Holder of the largest Percentage Interest of the Class A-UR Certificates shall act as “tax matters person” within the meaning of Treasury Regulations Section 1.860F-4(d) for each remaining REMIC created pursuant to this Agreement.  The Master Servicer is hereby designated as agent of such Class A-LR or Class A-UR Certificateholder for such purposes (or if the Master Servicer is not so permitted, such Holder shall be the tax matters person in accordance with the REMIC Provisions).  In such capacity, the Master Servicer shall, as and when necessary and appropriate, represent the related REMIC in any administrative or judicial proceedings relating to an examination or audit by any governmental taxing authority, request an administrative adjustment as to any taxable year of such REMIC, enter into settlement agreements with any governmental taxing agency, extend any statute of limitations relating to any tax item of such REMIC, and otherwise act on behalf of such REMIC in relation to any tax matter or controversy involving it.

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

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

The Trust Administrator shall treat the beneficial owners of the Class 1-A-13 Certificates as having entered into an interest rate cap contract with respect to all amounts payable to the Class 1-A-13 Certificates in excess of the Required Coupon.  Any payments to such Certificates in light of the foregoing shall not be payments with respect to a “regular interest” in a REMIC within the meaning of Code Section 860G(a)(1).  Thus, each Class 1-A-13 Certificate shall be treated as representing not only ownership of regular interests in the Master REMIC, but also ownership of an interest in an interest rate cap contract.  For tax information reporting purposes, the interest rate cap contract shall be deemed to have a value of $10,000 as of the Closing Date.

The parties intend that the portion of the Trust Fund constituting the Grantor Trust, consisting of the Class P Prepayment Charges, shall constitute, and that the affairs of the Grantor Trust shall be conducted so as to qualify such portion as, a "grantor trust" under subpart E, Part I of subchapter J of the Code, and the provisions hereof shall be interpreted consistently with this intention. In furtherance of such intention, the Master Servicer shall file or cause to be filed with the Internal Revenue Service together with Form 1041 or such other form as may be applicable and shall furnish or cause to be furnished the respective amounts described above to the Class P Certificateholders, in the time or times and in the manner required by the Code.

The Depositor will be responsible for any reasonable fees and expenses assessed or incurred by the Trust Administrator in connection with including any Additional Form 10-D Disclosure on Form 10-D pursuant to this paragraph.

(iii)

After preparing the Form 10-D, the Trust Administrator shall forward electronically a draft copy of the Form 10-D to the Depositor and the Master Servicer for review; provided, the Trust Administrator shall only be required to forward such draft Form 10-D to the Depositor, where such draft Form 10-D contains Additional Form 10-D Disclosure.

If a Form 10-D cannot be filed on time or if a previously filed Form 10-D needs to be amended, the Trust Administrator will follow the procedures set forth in Section 9.12(d)(ii).  Promptly (but no later than 1 Business Day) after filing with the Commission, the Trust Administrator will make available on its internet website a final executed copy of each Form 10-D filed by the Trust Administrator.  The signing party at the Master Servicer can be contacted at (410) 884-2000.  Each party to this Agreement acknowledges that the performance by the Trust Administrator of its duties under this Section 9.12 related to the timely preparation, execution and filing of Form 10-D is contingent upon such parties strictly observing all applicable deadlines in the performance of their duties under this Section 9.12.  The Trust Administrator shall have no liability for any loss, expense, damage or claim arising out of or with respect to any failure to properly prepare, execute and/or timely file such Form 10-D, where such failure results from the Trust Administrator’s inability or failure to obtain or receive, on a timely basis, any information from any other party hereto needed to prepare, arrange for execution or file such Form 10-D, not resulting from its own negligence, bad faith or willful misconduct.

In the event the Master Servicer determines that any such information has not been provided as required or is materially incorrect, the Master Servicer shall immediately notify the related Servicer and use its reasonable best efforts to cause such Servicer to provide or correct, as the case may be, such information promptly (but in any event in time to permit the Trust Administrator to make available the Distribution Date Statement at the time required in this Agreement).

The bid notice shall specify the Mortgage Loans and the REO Properties that are being sold, and identify the aggregate Clean-up Call REO Property Price required to be paid for the REO Properties and the other information necessary for the bidders to make bids.  The Master Servicer shall also be entitled to submit a bid for the Mortgage Loans and the REO Properties.  All bids must be submitted to the Master Servicer on a date determined by the Master Servicer, which date shall be set forth in the bid notice.  Only cash bids may be accepted.

If the Master Servicer elects to exercise its termination rights pursuant to clause (a) of Section 10.01, at least 5 days prior to the date notice is to be mailed to the affected Certificateholders, the Master Servicer shall notify the Depositor and the Trust Administrator of the date the Master Servicer intends to exercise its termination rights.

The Depositor for the benefit of the Certificateholders shall, to the extent consistent with this Agreement, take such actions as may be necessary to ensure that, if this Agreement were deemed to create a security interest in the Trust Fund, such security interest would be deemed to be a perfected security interest of first priority under applicable law and will be maintained as such throughout the term of the Agreement.

Series 2006-1

Representations and Warranties as to the Mortgage Loans

UBS Real Estate Securities Inc. (the “Transferor”) hereby makes with respect to those Mortgage Loans sold by it to the Depositor pursuant to the Mortgage Loan Purchase Agreement, the following representations and warranties as of the Closing Date or, if so specified herein, as of the Cut-off Date.  

(i)

The information set forth in the Mortgage Loan Schedule was true and correct in all material respects at the date or dates respecting which such information is furnished as specified in the Mortgage Loan Schedule;

(ii)

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

(iii)

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

(iv)

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

(v)

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

(vi)

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

(vii)

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

(viii)

Except for Mortgage Loans secured by co-op shares and Mortgage Loans secured by residential long term leases, the Mortgaged Property consists of a fee simple estate in real property; all of the improvements which are included for the purpose of determining the appraised value of the Mortgaged Property lie wholly within the boundaries and building restriction lines of such property and no improvements on adjoining properties encroach upon the Mortgaged Property (unless insured against under the related title insurance policy); and to the best of the Transferor’s knowledge, the Mortgaged Property and all improvements thereon comply with all requirements of any applicable zoning and subdivision laws and ordinances;

(ix)

The Mortgage Loan meets, or is exempt from, applicable state or federal laws, regulations and other requirements, pertaining to usury, and the Mortgage Loan is not usurious;

(x)

To the best of the Transferor’s knowledge, all inspections, licenses and certificates required to be made or issued with respect to all occupied portions of the Mortgaged Property and, with respect to the use and occupancy of the same, including, but not limited to, certificates of occupancy and fire underwriting certificates, have been made or obtained from the appropriate authorities;

(xi)

All payments required to be made up to but not including the Due Date immediately preceding the Cut-off Date for such Mortgage Loan under the terms of the related Mortgage Note have been made and no payment under any Mortgage Loan has been 30 days delinquent more than one time within twelve months prior to the Closing Date;

(xii)

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

(xiii)

Each Loan at the time it was made complied in all material respects with applicable federal, state and local laws, including, without limitation, all applicable anti-predatory and abusive lending laws;

(xiv)

The proceeds of the Mortgage Loans have been fully disbursed, there is no requirement for future advances thereunder and any and all requirements as to completion of any on site or off site improvements and as to disbursements of any escrow funds therefor have been complied with (except for escrow funds for exterior items which could not be completed due to weather and escrow funds for the completion of swimming pools); and all costs, fees and expenses incurred in making, closing or recording the Mortgage Loan have been paid, except recording fees with respect to Mortgages not recorded as of the Closing Date;

(xv)

The Mortgage Loan (except any Mortgage Loan secured by a Mortgaged Property located in any jurisdiction, as to which an opinion of counsel of the type customarily rendered in such jurisdiction in lieu of title insurance is instead received) is covered by an American Land Title Association mortgagee title insurance policy or other generally acceptable form of policy or insurance acceptable to Fannie Mae or Freddie Mac, issued by a title insurer acceptable to Fannie Mae or Freddie Mac insuring the originator, its successors and assigns, as to the first priority lien of the Mortgage in the original principal amount of the Mortgage Loan and subject only to (A) the lien of current real property taxes and assessments not yet due and payable, (B) covenants, conditions and restrictions, rights of way, easements and other matters of public record as of the date of recording of such Mortgage acceptable to mortgage lending institutions in the area in which the Mortgaged Property is located or specifically referred to in the appraisal performed in connection with the origination of the related Mortgage Loan, (C) liens created pursuant to any federal, state or local law, regulation or ordinance affording liens for the costs of clean up of hazardous substances or hazardous wastes or for other environmental protection purposes and (D) such other matters to which like properties are commonly subject which do not individually, or in the aggregate, materially interfere with the benefits of the security intended to be provided by the Mortgage; the Transferor is the sole insured of such mortgagee title insurance policy, the assignment to the Trustee of the Transferor’s interest in such mortgagee title insurance policy does not require any consent of or notification to the insurer which has not been obtained or made, such mortgagee title insurance policy is in full force and effect and will be in full force and effect and inure to the benefit of the Trustee, no claims have been made under such mortgagee title insurance policy, and no prior holder of the related Mortgage, including the Transferor, has done, by act or omission, anything which would impair the coverage of such mortgagee title insurance policy;

(xvi)

The Mortgaged Property securing each Mortgage Loan is insured by an insurer acceptable to Fannie Mae or Freddie Mac against loss by fire and such hazards as are covered under a standard extended coverage endorsement, in an amount which is not less than the lesser of 100% of the insurable value of the Mortgaged Property and the outstanding principal balance of the Mortgage Loan, but in no event less than the minimum amount necessary to fully compensate for any damage or loss on a replacement cost basis; if the Mortgaged Property is a condominium unit, it is included under the coverage afforded by a blanket policy for the project; if upon origination of the Mortgage Loan, the improvements on the Mortgaged Property were in an area identified in the Federal Register by the Federal Emergency Management Agency as having special flood hazards, a flood insurance policy meeting the requirements of the current guidelines of the Federal Insurance Administration is in effect with a generally acceptable insurance carrier, in an amount representing coverage not less than the least of (A) the outstanding principal balance of the Mortgage Loan, (B) the full insurable value of the Mortgaged Property and (C) the maximum amount of insurance which was available under the National Flood Insurance Act of 1968, as amended; and each Mortgage obligates the Mortgagor thereunder to maintain all such insurance at the Mortgagor’s cost and expense;

(xvii)

To the best of the Transferor’s knowledge no foreclosure action has been commenced or is currently threatened, with respect to the Mortgage Loan and the Transferor has not waived any default, breach, violation or event of acceleration;

(xviii)

No Mortgage Note or Mortgage is subject to any right of rescission, set off, counterclaim or defense, including the defense of usury, nor will the operation of any of the terms of the Mortgage Note or Mortgage, or the exercise of any right thereunder, render the Mortgage Note or Mortgage unenforceable, in whole or in part, or subject it to any right of rescission, set off, counterclaim or defense, including the defense of usury, and no such right of rescission, set off, counterclaim or defense has been asserted with respect thereto;

(xix)

Each Mortgage Note is payable in monthly payments, resulting in complete amortization of the Mortgage Loan over a term of not more than 360 months;

(xx)

Each Mortgage contains customary and enforceable provisions such as to render the rights and remedies of the holder thereof adequate for the realization against the Mortgaged Property of the benefits of the security, including realization by judicial foreclosure (subject to any limitation arising from any bankruptcy, insolvency or other law for the relief of debtors), and there is no homestead or other exemption available to the Mortgagor which would interfere with such right of foreclosure;

(xxi)

To the best of the Transferor’s knowledge, no Mortgagor is a debtor in any state or federal bankruptcy or insolvency proceeding;

(xxii)

(xxv)

In the event that the Mortgagor is an inter vivos “living” trust, (i) such trust is in compliance with Fannie Mae or Freddie Mac standards for inter vivos trusts and (ii) holding title to the Mortgaged Property in such trust will not diminish any rights as a creditor including the right to full title to the Mortgaged Property in the event foreclosure proceedings are initiated;

(xxvi)

If the Mortgage Loan is secured by a long-term residential lease, (1) the lessor under the lease holds a fee simple interest in the land; (2) the terms of such lease expressly permit the mortgaging of the leasehold estate, the assignment of the lease without the lessor’s consent and the acquisition by the holder of the Mortgage of the rights of the lessee upon foreclosure or assignment in lieu of foreclosure or provide the holder of the Mortgage with substantially similar protections; (3) the terms of such lease do not (a) allow the termination thereof upon the lessee’s default without the holder of the Mortgage being entitled to receive written notice of, and opportunity to cure, such default or (b) allow the termination of the lease in the event of damage or destruction as long as the Mortgage is in existence; (4) the term of such lease does not terminate earlier than five years after the maturity date of the Mortgage Note; and (5) the Mortgaged Property is located in a jurisdiction in which the use of leasehold estates in transferring ownership in residential properties is a widely accepted practice;

(xxviii)

The Mortgage Loan was underwritten in accordance with the underwriting guidelines of the related Loan Seller in effect at the time of origination with exceptions thereto exercised in a reasonable manner;

The Loan Seller used no adverse selection procedures in selecting the Mortgage Loan from among the outstanding first-lien, residential mortgage loans owned by it which were available for sale to the Transferor;

(xxx)

With respect to each Mortgage Loan, the Transferor is in possession of a complete Mortgage File except for the documents which have been delivered to the Trustee or which have been submitted for recording and not yet returned;

(xxxi)

As of the Cut-off Date, the range of original Loan-to-Value Ratios of the Mortgage Loans is 17.24% to 95.00% and 21 Mortgage Loans, representing 2.05% of the Cut-off Date Pool Balance, had Loan-to-Value Ratios at origination in excess of 80%.  Each such Mortgage Loan is subject to a Primary Insurance Policy;

(xxxii)

With respect to each Mortgage Loan that has a prepayment penalty feature, each such prepayment penalty is enforceable and, at the time such Mortgage Loan was originated, each prepayment penalty complied with applicable federal, state and local law, subject to federal preemption where applicable;

(xxxiii)

With respect to each Mortgage Loan, the related Servicing Agreement requires the related Servicer to deposit into the related Protected Account an amount equal to all payments of principal and interest on such Mortgage Loan that are delinquent at the close of business on the related Determination Date and not previously advanced by such Servicer.  The obligation of such Servicer to advance such payments as to such Mortgage Loan will continue through the final disposition or liquidation of the Mortgaged Property, unless such Servicer deems such advance to be nonrecoverable from liquidation proceeds, REO disposition proceeds, condemnation proceeds or insurance proceeds with respect to such Mortgage Loan; and

(xxxiv)

This Certificate is issued under and is subject to the terms, provisions and conditions of the Agreement, to which Agreement the Holder of this Certificate by virtue of the acceptance hereof assents and by which such Holder is bound.

No transfer of a Certificate of this Class 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 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 and such Certificateholder's prospective transferee shall each certify to the Trust Administrator in writing the facts surrounding the transfer or there shall be delivered 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 Holder hereof desiring to effect such transfer shall, and does hereby agree to, indemnify the Trust Administrator, the Trustee, the Master Servicer and the Depositor 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.

No transfer of an ERISA-Restricted Certificate shall be made unless the Trust Administrator shall have received either (i) a representation (letter) from the transferee of such Certificate, acceptable to and in form and substance satisfactory to the Trust Administrator, to the effect that such transferee is not an employee benefit plan or 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 company which is purchasing such Certificates with funds contained in an “insurance company general account” (as such term is defined in Section V(e) of Prohibited Transaction Class Exemption 95-60 (“PTCE 95-60”)) and 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 to the effect that the purchase or holding of such Certificate will not result in prohibited transactions under Section 406 of ERISA and/or Section 4975 of the Code and will not subject the Trustee, the Transferor, the Depositor, the Master Servicer or the Trust Administrator to any obligation in addition to those undertaken in the Agreement, which Opinion of Counsel shall not be an expense of such parties, the Master Servicer, the Trust Administrator or the Trust Fund.

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 without the Opinion of Counsel satisfactory to the Trust Administrator as described above shall be void and of no effect.

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

evidencing a percentage interest in the distributions allocable to the Certificates of the above-referenced Class with respect to a Trust Fund consisting primarily of fixed-rate mortgage loans (the “Mortgage Loans”) secured by first liens on one- to four-family residential properties

Mortgage Asset Securitization Transactions, Inc., as Depositor

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

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

[For Classes B-4, B-5, and B-6 Only]  [No transfer of a Certificate of this Class 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 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 and such Certificateholder’s prospective transferee shall each certify to the Trust Administrator in writing the facts surrounding the transfer.  In the event that such a transfer is to be made within three years from the date of the initial issuance of Certificates pursuant hereto, there shall also be delivered (except in the case of a transfer pursuant to Rule 144A of the Securities Act) to the Trust Administrator an Opinion of Counsel that such transfer may be made pursuant to an exemption from the Securities Act and such state securities laws, which Opinion of Counsel shall not be obtained at the expense of the Trustee, the Master Servicer, the Trust Administrator or the Depositor.  The Holder hereof desiring to effect such transfer shall, and does hereby agree to, indemnify the Trustee and the Trust Administrator and the Depositor 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.]

No transfer of an ERISA-Restricted Certificate shall be made unless the Trust Administrator shall have received either (i) a representation (letter) from the transferee of such Certificate, acceptable to and in form and substance satisfactory to the Trust Administrator, to the effect that such transferee is not an employee benefit plan or 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 company which is purchasing such Certificates with funds contained in an “insurance company general account” (as such term is defined in Section V(e) of Prohibited Transaction Class Exemption 95-60 (“PTCE 95-60”)) and 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 to the effect that the purchase or holding of such Certificate will not result in prohibited transactions under Section 406 of ERISA and/or Section 4975 of the Code and will not subject the Trustee, the Transferor, the Depositor, the Master Servicer or the Trust Administrator to any obligation in addition to those undertaken in the Agreement, which Opinion of Counsel shall not be an expense of such parties, the Master Servicer, the Trust Administrator or the Trust Fund.  (Such representations shall be deemed to have been made to the Trust Administrator by the Transferee’s acceptance of an ERISA-Restricted Certificate and by a beneficial owner’s acceptance of its interest in a Certificate of this Class.) 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 without the Opinion of Counsel satisfactory to the Trust Administrator as described above shall be void and of no effect.

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

This Certificate shall not be entitled to any benefit under the Agreement or be valid for any purpose unless manually countersigned by an authorized signatory of the Trust Administrator.

IN WITNESS WHEREOF, the Trust Administrator has caused this Certificate to be duly executed.

Mortgage Pass-Through Certificates, Series 2006-1

This Certificate is one of a duly authorized issue of Certificates designated as Mortgage Asset Securitization Transactions, Inc. MASTR Asset Securitization Trust 2006-1, Mortgage Pass-Through Certificates, of the Series specified on the face hereof (herein collectively called the “Certificates”), and representing a beneficial ownership interest in the Trust Fund created by the Agreement.

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

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

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

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

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

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

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

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

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

On any Distribution Date on which the Pool Principal Balance is less than 10% of the aggregate Cut-off Date Principal Balances of the Mortgage Loans, the Master Servicer will have the option to repurchase, in whole, from the Trust Fund all remaining Mortgage Loans and all property acquired in respect of the Mortgage Loans at a purchase price determined as provided in the Agreement.  In the event that no such optional termination occurs, the obligations and responsibilities created by the Agreement will terminate upon the later of the maturity or other liquidation (or any advance with respect thereto) of the last Mortgage Loan remaining in the Trust Fund or the disposition of all property in respect thereof and the distribution to Certificateholders of all amounts required to be distributed pursuant to the Agreement.  In no event, however, will the trust created by the Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants living at the date of the Agreement of a certain person named in the Agreement.

Any term used herein that is defined in the Agreement shall have the meaning assigned in the Agreement, and nothing herein shall be deemed inconsistent with that meaning.

COUNTY OF 

)

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

1.

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

2.

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

3.

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

4.

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

5.

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

6.

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

7.

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

8.

The Transferee’s taxpayer identification number is __________.

9.

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

10.

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

11.

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

12.

Check one of the following paragraphs:

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

(i)

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

(ii)

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

(iii)

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

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

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

(i)

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

EXHIBIT 2

to EXHIBIT I

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 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 provisions of this Agreement so long as the Transfer was registered after receipt of the related Transfer Affidavit, Transferor Certificate and either the Rule 144A Letter or the Investment Letter.  The Trust Administrator shall be entitled but not obligated to recover from any Holder of a Residual Certificate that was in fact not a Permitted Transferee at the time it became a Holder or, at such subsequent time as it became other than a Permitted Transferee, all payments made on such Residual Certificate at and after either such time.  Any such payments so recovered by the Trust Administrator shall be paid and delivered by the Trust Administrator to the last preceding Permitted Transferee of such Certificate.

(v)

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

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