THIS POOLING AND SERVICING AGREEMENT, dated as of February 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, “Custodian”) and JPMORGAN CHASE BANK, N.A., a banking association organized under the laws of the United States, as trustee (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. As provided herein, an election shall be made that the Trust Fund (exclusive of (i) the Interest Rate Swap Agreement, (ii) the Swap Account, (iii) the right to receive and the obligation to pay Net WAC Rate Carryover Amounts, (iv) the Net WAC Rate Carryover Reserve Account, (v) the Supplemental Interest Trust, (vi) any prepayment charges other than the Class P Prepayment Charges and (vii) the obligation to pay Class IO Distribution Amounts (collectively, the “Excluded Trust Assets”)) be treated for federal income tax purposes as comprising three real estate mortgage investment conduits under Section 860D of the Code (each a “REMIC” or, in the alt ernative the “Subsidiary REMIC,” the “Middle REMIC,” and the “Master REMIC”). Any inconsistencies or ambiguities in this Agreement or in the administration of this Agreement shall be resolved in a manner that preserves the validity of such REMIC elections.

Each Certificate, other than the Class R Certificate, represents ownership of a regular interest in the Master REMIC for purposes of the REMIC Provisions. In addition, each Certificate, other than the Class R, Class CE and Class P Certificates, represents (i) the right to receive payments with respect to any Net WAC Rate Carryover Amounts and (ii) the obligation to pay Class IO Distribution Amounts. The Class R Certificate represents ownership of the sole Class of residual interest in each of the Subsidiary REMIC, the Middle REMIC, and the Master REMIC for purposes of the REMIC Provisions.

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

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

Subsidiary REMIC:

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

(1)

For any Distribution Date (and the related Accrual Period) the interest rate for this Lower-Tier Interest shall be the weighted average of the Net Mortgage Rates of the Mortgage Loans as of the first day of the preceding calendar month (the “Subsidiary REMIC Net WAC”).

(2)

For any Distribution Date (and the related Accrual Period) the interest rate for each of these Lower Tier Interests shall be the lesser of (i) the REMIC Swap Rate for such Distribution Date, and (ii) the product of (a) the Subsidiary REMIC Net WAC and (b) 2.

(3)

For any Distribution Date (and the related Accrual Period) the interest rate for each of these Lower Tier Interests shall be the excess, if any, of (i) the product of (a) the Subsidiary REMIC Net WAC and (b) 2, over (ii) the REMIC Swap Rate for such Distribution Date.

(4)

The initial principal balance of this Subsidiary REMIC interest shall equal the excess of (i) the Pool Balance as of the Cut-off Date over (ii) the aggregate of the initial principal balances of each remaining Subsidiary REMIC interest.

(5)

The LT-R interest shall not have a principal amount and shall not bear interest. The LT-R interest is hereby designated as the sole class of residual interest in the Subsidiary REMIC.

On each Distribution Date, the Trust Administrator shall first pay or charge as an expense of the Subsidiary REMIC all expenses of the Trust Fund for such Distribution Date, other than any Net Swap Payment or Swap Termination Payment.

On each Distribution Date the Trust Administrator shall distribute the aggregate Interest Remittance Amount for the Mortgage Pool (net of expenses described in the preceding paragraph) with respect to each of the interests in the Subsidiary REMIC based on the above-described interest rates.

On each Distribution Date, the Trust Administrator shall distribute the aggregate Principal Distribution Amount with respect to the interests in the Subsidiary REMIC, first, to the Class LT-M7 Interest until its principal balance equals the principal balance of the Class M-7 Certificates, second, to the Class LT-M8 Interest until its principal balance equals the principal balance of the Class M-8 Certificates, third, to the Class LT-A Interest until its principal balance is reduced to zero, and finally, sequentially, to the other interests in the Subsidiary REMIC in ascending order of their numerical class designation, and, with respect to each pair of classes having the same numerical designation, in equal amounts to each such class, until the principal balance of each such class is reduced to zero. All losses on the Mortgage Loans shall be allocated among the interests in the Subsidiary REM IC in the same manner that principal distributions are allocated.

On each Distribution Date, the Trust Administrator shall distribute the Class P Prepayment Charges collected during the preceding Prepayment Period, in the case of Principal Prepayments in full, or during the related Prepayment Period, in the case of Principal Prepayments in part, to the Class LT-F54 and Class LT-V54 Subsidiary REMIC Regular Interests, respectively.

Middle REMIC:

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

Middle REMIC Interest Class Designation	Middle REMIC Interest Rate	Initial Class Principal Amount	Corresponding Class of Certificate(s)
Class MT-A	(1)	(5)	A
Class MT-M1	(1)	(5)	M-1
Class MT-M2	(1)	(5)	M-2
Class MT-M3	(1)	(5)	M-3
Class MT-M4	(1)	(5)	M-4
Class MT-M5	(1)	(5)	M-5
Class MT-M6	(1)	(5)	M-6
Class MT-M7	(1)	(5)	M-7
Class MT-M8	(1)	(5)	M-8
Class MT-Q	(1)	(2)	N/A
Class MT-IO	(3)	(3)	N/A
Class MT-R	(4)	(4)	R

___________________________

(1)

For any Distribution Date (and the related Accrual Period) the interest rate for each of these interests in the Middle REMIC is a per annum rate equal to the weighted average of the interest rates on the interests in the Subsidiary REMIC for such Distribution Date, provided, however, that for any Distribution Date on which the Class MT-IO Interest is entitled to a portion of the interest accruals on an interest in the Subsidiary REMIC having an “F” in its class designation, as described in footnote three below, such weighted average shall be computed by first subjecting the rate on such interest to a cap equal to the product of (a) 2 and (b) Swap LIBOR for such Distribution Date.

(2)

The initial class principal amount of this Middle REMIC interest shall equal the excess of (i) the Pool Balance as of the Cut-off Date over (ii) the aggregate of the initial class principal amounts of each remaining Middle REMIC interest.

(3)

The Class MT-IO is an interest only class that does not have a principal balance. For only those Distribution Dates listed in the first column in the table below, the Class MT-IO shall be entitled to interest accrued on the Subsidiary REMIC Regular Interests listed in the second column in the table below at a per annum rate equal to the excess, if any, of (i) the interest rate for such Subsidiary REMIC Regular Interests for such Distribution Date over (ii) the product of (a) 2 and (b) Swap LIBOR for such Distribution Date.

(4)

The Class MT-R interest is the sole class of residual interests in the Middle REMIC. It does not have an interest rate or a principal balance.

(5)

The initial class principal amount of this Middle REMIC interest shall equal one-half of the initial class principal amount of its Corresponding Class of Certificates.

On each Distribution Date, interest shall be distributed on the interests in the Middle REMIC based on the above-described interest rates, provided, however, that interest that accrues on the Class MT-Q Interest shall be deferred in an amount equal to one-half of the increase, if any, in the Overcollateralization Amount for such Distribution Date. Any interest so deferred shall itself bear interest at the interest rate for the Class MT-Q Interest. An amount equal to the interest so deferred shall be distributed as additional principal on the other interests in the Middle REMIC having a principal balance in the manner described under priority (a) below.

On each Distribution Date principal shall be distributed, and Realized Losses shall be allocated, among the interests in the Middle REMIC in the following order of priority:

(a) First, to the Class MT-A, Class MT-M1, Class MT-M2, Class MT-M3, Class MT-M4, Class MT-M5, Class MT-M6, Class MT-M7, and Class MT-M8 Interests until the principal balance of each such interest equals one-half of the Class Principal Balance of the Corresponding Class of Certificates immediately after such Distribution Date; and

(b) Second, to the Class MT-Q Interests, any remaining amounts.

On each Distribution Date, the Trustee shall be deemed to have distributed the Class P Prepayment Charges passed through with respect to the Class LT-F54 and Class LT-V54 interests in the Subsidiary REMIC on such Distribution Date to the Class MT-Q Interest.

Master REMIC

As provided herein, the Trust Administrator shall elect to treat the segregated pool of assets consisting of the Middle REMIC Regular Interests as a REMIC for federal income tax purposes, and such segregated pool of assets shall be designated as the “Master REMIC.” The Master REMIC shall also issue Class R-III Interest, which shall evidence the sole class of “residual interests” in the Master REMIC for purposes of the REMIC Provisions under federal income tax law. The following table irrevocably sets forth the designation, the Pass-Through Rate, and the initial aggregate Certificate Principal Balance for the indicated Class of Certificates.

Designation	Pass-Through Rate	Initial Aggregate Certificate Principal Balance	Latest Possible Maturity Date⁽¹⁾
Class A	Variable⁽²⁾	$ 229,369,000	March 2036
Class M-1	Variable⁽²⁾	$ 30,044,000	March 2036

_______________

⁽¹⁾

For purposes of Section 1.860G-1(a)(4)(iii) of the Treasury regulations, the Latest Possible Maturity Date has been designated as the “latest possible maturity date” for each Class of Certificates.

⁽²⁾

The Pass-Through Rate on any Distribution Date with respect to the Class A and Mezzanine Certificates is the lesser of (a) the related Formula Rate and (b) the Net WAC Rate Cap for such Distribution Date. For purposes of the REMIC Provisions, the reference to “Net WAC Rate Cap” in the definition of “Pass-Through Rate” shall be deemed to be a reference to the REMIC Net Funds Cap; therefore: on any Distribution Date on which the Pass-Through Rate for a Class of Certificates exceeds the REMIC Net Funds Cap, interest accruals based on such excess shall be treated as having been paid from the Net WAC Rate Carryover Reserve Account or the Supplemental Interest Trust, as applicable; on any Distribution Date on which the Pass-Through Rate on a Class of Certificates is based on the Net WAC Rate Cap, the amount of interest that would have accrued on such Class of Certificates if the R EMIC Net Funds Cap were substituted for the Net WAC Rate Cap shall be treated as having been paid by Certificateholders of such Class of Certificates to the Supplemental Interest Trust, all pursuant to and as further provided in Section 4.06 hereof.

⁽³⁾

The Class CE Certificate shall represent beneficial ownership of a regular interest in the Master REMIC (the “Class CE Interest”). The Class CE Interest will accrue interest at its variable Pass-Through Rate on the Notional Amount of the Class CE Interest outstanding from time to time. For purposes of the REMIC Provisions, Class CE Interest shall have an initial principal balance of $377.00, and the right to receive distributions of such amount represents a regular interest in the Master REMIC. The Class CE Interest shall also comprise two notional components, each of which represents a regular interest in the Master REMIC. The first such component has a notional balance that will at all times equal the aggregate of the Class Principal Amounts of the Middle Tier Interests in the Middle REMIC, and, for each Distribution Date (and the related Accrual Period) this notional component shall bear interest at a per annum rate equal to the excess, if any, of (i) (a) the weighted average of the interest rates on the Middle REMIC Regular Interests (other than any interest-only regular interest), over (ii) the Adjusted WAC. The second notional component represents the right to receive all distributions in respect of the Class MT-IO Interest in the Middle REMIC (the “SWAP-IO Interest”). In addition, for purposes of the REMIC Provisions, the Class CE Certificate shall represent beneficial ownership of (i) the Net WAC Rate Carryover Reserve Account; (ii) the Supplemental Interest Trust, including the Swap Agreement and Swap Account; and (iii) an interest in the notional principal contracts described in Section 4.06 hereof.

⁽⁴⁾

The Class P Certificate will not accrue interest.

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

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

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

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

Upon receiving each Final Certification from the Custodian, the Trustee shall notify the Transferor of any document defects listed as exceptions in each such Final Certification. The Transferor shall promptly correct or cure such document defects, and if the Transferor fails to correct or cure the defect within ninety (90) days of the earlier of its discovery or its receipt of written notice 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 Service r 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 Servicing Agreement, the Master Servicer shall cause the Servicer 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 Servicer from time to time.

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

Section 2.03

Remedies for Breaches of Representations and Warranties.

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

Upon discovery by any of the parties hereto 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. 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 Transf eror 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 Mortgage Loans into the Trust Fund, in the manner and subject to the conditions set forth in this Section; or (ii) repurchase the affected Mortgage Loan or Mortgage Loans from the Trustee at the Purchase Price in the manner set forth below. The Transferor shall promptly reimburse the Master Servicer, the NIMS Insurer and the Trustee for any expenses reasonably incurred by the Master Servicer, the NIMS Insurer or the Trustee in respect of enforcing the remedies for such breach by the Transferor.

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

With respect to substitutions made by the Transferor, Scheduled Payments due with respect to Eligible Substitute Mortgage Loans in the month of substitution shall not be part of the Trust Fund and will be retained by the Transferor on the next succeeding Distribution Date. For the month of substitution, distributions to Certificateholders will include the monthly payment due on any Deleted Mortgage Loan for such month and thereafter the Transferor shall be entitled to retain all amounts received in respect of such Deleted Mortgage Loan. The Custodian shall amend the Mortgage Loan Schedule for the benefit of the Certificateholders to reflect the removal of such Deleted Mortgage Loan and the substitution of the Eligible Substitute Mortgage Loan or Mortgage Loans and the Custodian shall deliver the amended Mortgage Loan Schedule to the Trustee. Upon such substitution, the Eligible Su bstitute Mortgage Loan or Mortgage 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 Mortgage 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 Trust ee’s interest in any Deleted Mortgage Loan substituted for pursuant to this Section 2.03.

For any month in which the Transferor substitutes one or more Eligible Substitute Mortgage Loans for one or more Deleted Mortgage Loans, the Master Servicer will determine the amount (if any) by which the aggregate principal balance of all such Eligible Substitute Mortgage Loans as of the date of substitution is less than the aggregate Principal Balance of all such Deleted Mortgage Loans (after application of the scheduled principal portion of the monthly payments 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 agree d that the obligation under this Agreement of the Transferor to cure, repurchase or replace any Mortgage Loan as to which a breach has occurred and is continuing shall constitute the sole remedies against the Transferor respecting such matters available to Certificateholders, the Master Servicer, the NIMS Insurer, the Depositor, the Trust Administrator or the Trustee on their behalf.

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

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 the 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 d ata provided to the Master Servicer by the Servicer and shall cause the Servicer to perform and observe the covenants, obligations and conditions to be performed or observed by the Servicer under the Servicing Agreement.

(B)

second, on any Distribution Date on which the aggregate Certificate Principal Balance of the Class A Certificates and the Mezzanine Certificates has been reduced to zero, any remaining amounts in reduction of the Certificate Principal Balance of the Class CE Certificates, until the Certificate Principal Balance thereof has been reduced to zero;

(C)

third, to the Holders of the Class CE Certificates;

(iii)

(iv)

fourth, any remaining amounts to the Holders of the Class R Certificates.

(e)

After the distributions set forth in Section 4.01(a), (b), (c) and (d), an amount equal to the amount of Subsequent Recoveries remitted to the Master Servicer shall be applied to increase the Certificate Principal Balance of the Class of Certificates with the Highest Priority up to the extent of such Realized Losses previously allocated to that Class of Certificates pursuant to Section 4.02. An amount equal to the amount of any remaining Subsequent Recoveries shall be applied to increase the Certificate Principal Balance of the Class of Certificates with the next Highest Priority, up to the amount of such Realized Losses previously allocated to that Class of Certificates pursuant to Section 4.02. Holders of such Certificates will not be entitled to any distribution in respect of interest on the amount of such increases for any Accrual Period preceding the Distribution Date on which suc h increase occurs. Any such increases shall be applied to the Certificate Principal Balance of each Certificate of such Class in accordance with its respective Percentage Interest.

Section 4.02

(a)

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

The Certificate Principal Balance of any certificate may not be reduced more than once in respect of any particular amount both (i) allocable to such certificate in respect of Realized Losses and (ii) distributable as principal to the holder of such certificate from Net Monthly Excess Cashflow.

The Trust Administrator’s responsibility for disbursing the above information to the Master Servicer, the Trustee, the NIMS Insurer, Depositor, Certificateholders and other interested parties is limited to the availability, timeliness and the accuracy of the information provided by the Servicer. The Trust Administrator will make a copy of each statement provided pursuant to this Section 4.03 (and, at its option, any additional files containing the same information in an alternative format) available each month to Certificateholders, the NIMS Insurer and other interested parties, and other parties to this Agreement via the Trust Administrator’s internet website located at “www.ctslink.com”. Assistance in using the internet website can be obtained by calling the Trust Administrator’s customer service desk at ###-###-####. Parties that are unable to use th e 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 Servicer) 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 4.03 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 4.04

Net WAC Rate Carryover Reserve Account.

No later than the Closing Date, the Trust Administrator shall establish and maintain with itself a separate, segregated trust account titled, “Wells Fargo Bank, N.A., as Trust Administrator, in trust for the registered holders of MASTR Second Lien Trust 2006-1, Mortgage Pass-Through Certificates, Series 2006-1—Net WAC Rate Carryover Reserve Account.” All amounts deposited in the Net WAC Rate Carryover Reserve Account shall be distributed to the Holders of the Class A Certificates and/or the Mezzanine Certificates in the manner set forth in Section 4.01(b).

On each Distribution Date as to which there is a Net WAC Rate Carryover Amount payable to the Class A Certificates and/or the Mezzanine Certificates, the Trust Administrator has been directed by the Class CE Certificateholders to, and therefore will, deposit into the Net WAC Rate Carryover Reserve Account the amounts described in Section 4.01(b)(iii), rather than distributing such amounts to the Class CE Certificateholders. On each such Distribution Date, the Trust Administrator shall hold all such amounts for the benefit of the Holders of the Class A Certificates and the Mezzanine Certificates, and will distribute such amounts to the Holders of the Class A Certificates and the Mezzanine Certificates, as applicable, in the amounts and priorities set forth in Section 4.01(b).

For federal and state income tax purposes, the Class CE Certificateholders will be deemed to be the owner of the Net WAC Rate Carryover Reserve Account. All amounts deposited into the Net WAC Rate Carryover Reserve Account shall be treated as amounts distributed to the Holder of the Class CE Interest. The Net WAC Rate Carryover Reserve Account will be an “outside reserve fund” within the meaning of Treasury Regulation Section 1.860G-2(h). Upon the termination of the Trust, or the payment in full of the Class A and the Mezzanine Certificates, all amounts remaining on deposit in the Net WAC Rate Carryover Reserve Account will be released by the Trust and distributed to the Trust Administrator or its designee. The Net WAC Rate Carryover Reserve Account will be part of the Trust but not part of any REMIC and any payments to t he Holders of the Class A Certificates and the Mezzanine Certificates of Net WAC Rate Carryover Amounts will not be payments with respect to a “regular interest” in a REMIC within the meaning of Code Section 860G(a)(1).

By accepting a Class CE Certificate, each Class CE Certificateholder hereby agrees to direct the Trust Administrator, and the Trust Administrator hereby is directed, to deposit into the Net WAC Rate Carryover Reserve Account the amounts described above on each Distribution Date as to which there is any Net WAC Rate Carryover Amount rather than distributing such amounts to the Class CE Certificateholders. By accepting a Class CE Certificate, each Class CE Certificateholder further agrees that such direction is given for good and valuable consideration, the receipt and sufficiency of which is acknowledged by such acceptance.

Amounts on deposit in the Net WAC Rate Carryover Reserve Account shall remain uninvested.

Section 4.05

Supplemental Interest Trust.

A separate trust is hereby established (the “Supplemental Interest Trust”), the corpus of which shall be held by the Trustee, in trust, for the benefit of the holders of the Class A Certificates and the Mezzanine Certificates.

Section 4.06

Swap Account.

(a)

No later than the Closing Date, the Trust Administrator shall establish and maintain with itself, as agent for the Trustee, a separate, segregated trust account titled, “Wells Fargo Bank, N.A. as Trustee, in trust for the registered holders of MASTR Second Lien Trust 2006-1, Mortgage Pass-Through Certificates, Series 2006-1—Swap Account” (the “Swap Account”). Such account shall be an Eligible Account and amounts therein shall be held uninvested. The Swap Account shall be an asset of the Supplemental Interest Trust, but shall not be an asset of any REMIC.

(b)

On each Distribution Date, prior to any distribution to any Certificate, the Trust Administrator shall deposit into the Swap Account: (i) the amount of any Net Swap Payment or Swap Termination Payment (other than any Swap Termination Payment resulting from a Swap Provider Trigger Event) owed to the Swap Provider (after taking into account any upfront payment received from the counterparty to a replacement swap agreement) from funds collected and received with respect to the Mortgage Loans prior to the determination of Available Funds and (ii) amounts received by the Trust Administrator from the Swap Administrator, for distribution in accordance with subsection (d) below, pursuant to the Swap Administration Agreement. For federal income tax purposes, any amounts paid to the Swap Provider on each Distribution Date shall first be deemed paid in respect of the Class SWAP-IO Interest to the exten t of the amount distributable on such Class SWAP-IO Interest on such Distribution Date, and any remaining amount shall be deemed paid in respect of a Class IO Distribution Amount (as defined below).

(c)

For federal income tax purposes, the Swap Account shall be owned by the beneficial owners of the Class CE Certificates.

(d)

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

Section 4.07

Tax Treatment of Swap Payments and Swap Termination Payments.

For federal income tax purposes, each holder of a Class A or Mezzanine Certificate is deemed to own an undivided beneficial ownership interest in a REMIC regular interest and the right to receive payments from either the Net WAC Rate Carryover Reserve Account or the Swap Account in respect of the Net WAC Rate Carryover Amount or the obligation to make payments to the Swap Account. For federal income tax purposes, the Trust Administrator will account for payments to each Class A and Mezzanine Certificates as follows: each Class A and Class M Certificate will be treated as receiving their entire payment from the Master REMIC (regardless of any Swap Termination Payment or obligation under the Interest Rate Swap Agreement) and subsequently paying their portion of any Swap Termination Payment in respect of each such Class’ obligation under the Interest Rate Swap Agreement.

Section 4.08

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 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 Ad ministrator 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 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 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 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 Accrual Period to Certificate Owners or Holders of LIBOR Certificates who place a telephone call to the Trust Administrator at ###-###-#### and make a request therefor.

Section 4.09

Advances.

The Master Servicer shall deposit in the Distribution Account not later than the Distribution Account Deposit Date immediately preceding the related Distribution Date an Advance in an amount equal to the difference between (x) with respect to each Scheduled Payment due on a Mortgage Loan that is delinquent (other than as a result of a Relief Act Reduction) and for which the related Servicer was required to make an Advance pursuant to the related Servicing Agreement and (y) amounts deposited in the Collection Account to be used for Advances with respect to such Mortgage Loan, except to the extent the Master Servicer determines any such Advance to be a Nonrecoverable Advance. Subject to the foregoing, the Master Servicer shall continue to make such Advances for so long as the related Servicer is required to do so under the related Servicing Agreement. If applicable, on the Distribution Ac count Deposit Date, the Master Servicer shall deliver an Officer’s Certificate to the Trust Administrator stating that the Master Servicer elects not to make an Advance in a stated amount and detailing the reason(s) it deems the Advance to be a Nonrecoverable Advance. Any amounts deposited by the Master Servicer pursuant to this Section 4.09 shall be net of the Servicing Fee and the Master Servicing Fee, if applicable, for the related Mortgage Loans.

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)

(i) No transfer of a Private Certificate shall be made unless such transfer is made pursuant to an effective registration statement under the Securities Act and any applicable state securities laws or is exempt from the registration requirements under said Act and such state securities laws. In the event that a transfer is to be made in reliance upon an exemption from the Securities Act and such laws, in order to assure compliance with the Securities Act and such laws, the Certificateholder desiring to effect such transfer (other than the Depositor or an affiliate of the Depositor) shall certify to the Trust Administrator in writing the facts surrounding the transfer in substantially the 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 NIMS Insurer, the Depositor, and the Master Servicer against any liability that may result if the transfer is not so exempt or is not made in accordance with such federal and state laws.

(ii)

No transfer of an ERISA-Restricted Certificate shall be made (other than to the Depositor or an affiliate of the Depositor) unless the Trust Administrator shall have received in accordance with Exhibit K or Exhibit L (in the event such Certificate is a Private Certificate) or paragraph 13 of Exhibit I (in the event such Certificate is a Residual Certificate), in form and substance satisfactory to such Trust Administrator (i) a representation that such transferee is not an employee benefit plan or other retirement arrangement subject to Section 406 of ERISA and/or Section 4975 of the Code, or a person acting for, on behalf of or with the assets of, any such plan or arrangement, (ii) in the case of an ERISA-Restricted Certificate which is the subject of an ERISA-Qualifying Underwriting, other than the Class P Certificates, if the purchaser is an insurance company, a representation that the purchaser is an insurance company which is purchasing such Certificates with funds contained in an “insurance company general account” (as such term is defined in Section V(e) of Prohibited Transaction Class Exemption 95-60 (“PTCE 95-60”)) and that the purchase and holding of such Certificates are covered under Sections I and III of PTCE 95-60 or (iii) an Opinion of Counsel satisfactory to the Trust Administrator, which Opinion of Counsel shall not be an expense of the Trustee, the Trust Administrator, the NIMS Insurer, the Depositor, the Transferor, the Master Servicer or the Trust Fund, addressed to the Trust Administrator to the effect that the purchase or holding of such ERISA-Restricted Certificate will not result in non-exempt prohibited transactions under Section 406 of ERISA and/or Section 4975 of the Code and will not subject the Trustee, the Trust Administrator, the Depositor, the Transferor or the Master Servicer to any obligation in addition to those expressly undert aken 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.

(iii)

No transfer of an ERISA-Restricted Swap Certificate prior to the termination of the Interest Rate Swap Agreement shall be made unless the Trust Administrator shall have received a representation letter from the transferee of such Certificate, substantially in the form set forth in Exhibit K or Exhibit L (in the event such Certificate is a Private Certificate), to the effect that either (i) such transferee is neither a Plan nor a Person acting on behalf of any such Plan or using the assets of any such Plan to effect such transfer or (ii) the acquisition and holding of the ERISA-Restricted Swap Certificate are eligible for exemptive relief under Prohibited Transaction Class Exemption (“PTCE”) 84-14, PTCE 90-1, PTCE 91-38, PTCE 95-60 or PTCE 96-23. Notwithstanding anything else to the contrary herein, any purported transfer of an ERISA-Restricted Swap Certificate on behalf of a Plan without the delivery to the Trust Administrator of a representation letter as described above shall be void and of no effect. If the ERISA-Restricted Swap Certificate is a Book-Entry Certificate, the transferee will be deemed to have made a representation as provided in clause (i) or (ii) of this paragraph, as applicable.

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

To the extent permitted under applicable law (including, but not limited to, ERISA), the Trust Administrator shall be under no liability to any Person for any registration of transfer of any ERISA-Restricted Swap Certificate that is in fact not permitted by this Section 5.02(b)(iii) or for making any payments due on such Certificate to the Holder thereof or taking any other action with respect to such Holder under the provisions of this Agreement so long as the transfer was registered by the Trust Administrator in accordance with the foregoing requirements.

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 pr ovisions 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 NIMS Insurer, the Transferor or the Master Servicer, to the effect that the elimination of such restrictions will not cause any REMIC hereunder to fail to qualify as a REMIC at any time that the Certificates are outstanding or result in the imposition of any tax on the Trust Fund, a Certificateholder or another Person. Each Person holding or acquiring any Ownership Interest in a Residual Certificate hereby consents to any amendment of this Agreement which, based on an Opinion of Counsel fur nished 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.

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 Partici pants 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.

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 Definitiv e Certificates all references herein to obligations imposed upon or to be performed by the Depository shall be deemed to be imposed upon and performed by the Trust Administrator, to the extent applicable with respect to such Definitive Certificates and the Trust Administrator shall recognize the Holders of the Definitive Certificates as Certificateholders hereunder; provided that the Trust Administrator shall not by virtue of its assumption of such obligations become liable to any party for any act or failure to act of the Depository.

Section 5.03

Mutilated, Destroyed, Lost or Stolen Certificates.

If (a) any mutilated Certificate is surrendered to the Trust Administrator, or the Trust Administrator receives evidence to its satisfaction of the destruction, loss or theft of any Certificate and (b) there is delivered to the Master Servicer, the NIMS Insurer and the Trust Administrator such security or indemnity as may be required by them to save each of them harmless, then, in the absence of notice to the Trust Administrator that such Certificate has been acquired by a bona fide purchaser, the Trust Administrator shall execute, countersign and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a new Certificate of like Class, tenor and Percentage Interest. In connection with the issuance of any new Certificate under this Section 5.03, the Trust Administrator may require the payment of a sum sufficient to cover any tax or other governmental ch arge 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.

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 4.09. 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 h as 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 4.09 hereof or if it is otherwise unable to so act, or if it has been requested in writing by the NIMS Insurer or Holders of Certificates evidencing not less than 25% of the Voting Rights evidenced by the Certificates to do so, appoint, or petition a court of competent jurisdiction to appoint, any established mortgage loan servicing institution the appointment of which does not adversely affect the then current rating of the Certificates by each Rating Agency as the successor to the Master Servicer hereunder in the assumption of all or any part of the responsibilities, duties or liabilities of the Master Servicer hereunder. Any successor to the Master Servicer shall be an institution which is a Fannie Mae and Freddie Mac approved seller/servicer in good standing, which has a ne t worth of at least $15,000,000, and which is willing to master service the Mortgage Loans and executes and delivers to the Depositor and the Trustee an agreement accepting such delegation and assignment, which contains an assumption by such Person of the rights, powers, duties, responsibilities, obligations and liabilities of the Master Servicer (other than liabilities of the Master Servicer under Section 6.03 hereof incurred prior to termination of the Master Servicer under Section 7.01), with like effect as if originally named as a party to this Agreement; and provided further that each Rating Agency acknowledges that its rating of the Certificates in effect immediately prior to such assignment and delegation will not be qualified or reduced, without regard to the guaranty provided by the Policies, as a result of such assignment and delegation. Pending appointment of a successor to the Master Servicer hereunder, the Trustee, unless the Trustee is prohibited by law from so acting, shall, subject to S ection 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 Servicer of such change of master servicer and shall, during the term of its service as master servicer enforce the requirement of the Servicer to maintain in force the policy or policies pursuant to Section 3.11.

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

(b)

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

Duties of Trustee.

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

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

(i)

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

(ii)

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

(iii)

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

(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 the Certificates;

(h)

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

(i)

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

(j)

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

(k)

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

(l)

pay, from the sources specified in the last paragraph of this Section 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 R 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 R 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 t o 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.

The Depositor hereby indemnifies the Master Servicer for any losses, liabilities, damage s, 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 case s, 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).

In the event such notice is given in connection with the purchase of all of the Mortgage Loans and each REO Property remaining in the Subsidiary REMIC by the Master Servicer, the Master Servicer shall deliver to the Trust Administrator for deposit in the Distribution Account not later than the last Business Day of the month next preceding the month of the final distribution on the Certificates an amount in immediately available funds equal to the Termination Price. The Trust Administrator shall remit to the Master Servicer from such funds deposited in the Distribution Account (i) any amounts which the Master Servicer would be permitted to withdraw and retain from the Collection Account pursuant to Section 3.10 and (ii) any other amounts otherwise payable by the Trust Administrator to the Master Servicer from amounts on deposit in the Distribution Account pursuant to the terms of this Agreemen t, in each case prior to making any final distributions pursuant to Section 4.01.

Upon presentation of the Certificates by the Certificateholders on the final Distribution Date, the Trust Administrator shall distribute to each Certificateholder so presenting and surrendering its Certificates the amount otherwise distributable on such Distribution Date in accordance with Section 4.01 in respect of the Certificates so presented and surrendered. Any funds not distributed to any Holder or Holders of Certificates being retired on such Distribution Date because of the failure of such Holder or Holders to tender their Certificates shall, on such date, be set aside and held in trust and credited to the account of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to this Section 10.01 shall not have been surrendered for cancellation within six months after the time specified in such notice, the Trust Administrator shall mail a second notice to the remaining non-tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Trust Administrator shall, directly or through an agent, mail a final notice to the remaining non-tendering Certificateholders concerning surrender of their Certificates. The costs and expenses of maintaining the funds in trust and of contacting such Certificateholders shall be paid out of the assets remaining in the Trust Fund. If within one year after the final notice any such Certificates shall not have been surrendered for cancellation, the Trust Administrator shall pay to UBS Securities LLC, all such amounts, and all rights of non-tendering Certificateholders in or to such amounts shall thereupon cease. No interest shall accrue or be payable to any Certificateholder on any a mount held in trust by the Trust Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with this Section 9.01. Any such amounts held in trust by the Trust Administrator shall be held in an Eligible Account and the Trust Administrator may direct any depository institution maintaining such account to invest the funds in one or more Permitted Investments. All income and gain realized from the investment of funds deposited in such accounts held in trust by the Trust Administrator shall be for the benefit of the Trust Administrator; provided, however, that the Trust Administrator shall deposit in such account the amount of any loss of principal incurred in respect of any such Permitted Investment made with funds in such accounts immediately upon the realization of such loss.

Immediately following the deposit of funds in trust hereunder in respect of the Certificates, the Trust Fund shall terminate.
