THIS POOLING AND SERVICING AGREEMENT, dated as of July 1, 2007, among I ASSET SECURITIZATION CORPORATION, as depositor (the “Depositor”), ▇▇▇▇▇ FARGO BANK, N.A., a national banking association, as master servicer (the “Master Servicer”), securities administrator (the “Securities Administrator”), and custodian (the “Custodian”) and DEUTSCHE BANK NATIONAL TRUST COMPANY, a national banking association, as trustee (the “Trustee”).

WITNESSETH:

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

PRELIMINARY STATEMENT:

The Depositor intends to sell Mortgage Pass-Through Certificates (collectively, the “Certificates”), to be issued hereunder in multiple classes, which in the aggregate will evidence the entire beneficial ownership interest in the Trust Fund (as defined herein). As provided herein, the Securities Administrator, on behalf of the Trust, will make an election to treat the entire segregated pool of assets relating to the Mortgage Loans, as described in the definition of REMIC 1 below, as a real estate mortgage investment conduit (a “REMIC”) for federal income tax purposes, and such segregated pool of assets will be designated as “REMIC 1.” The Class R-1 Interest, beneficial ownership of which is evidenced by the Class R Certificates, will represent the sole class of “residual interests” in REMIC 1 for purposes of the REMIC Provisions (as defined herein) under federal income tax law. The following table irrevocably sets forth the designation, the REMIC 1 Remittance Rate, the initial Uncertificated Principal Balance, and solely for purposes of satisfying Treasury Regulation Section 1.860G-1(a)(4)(iii), the “latest possible maturity date” for each of the REMIC 1 Regular Interests. None of the REMIC 1 Regular Interests will be certificated.

Uncertificated REMIC I Regular Interest III-A	Variable Rate(2)	$	519.24	September 25, 2037
Uncertificated REMIC I Regular Interest III-B	Variable Rate(2)	$	10,930.24	September 25, 2037

Uncertificated REMIC I Regular Interest R-II		$	50.00	September 25, 2037

As provided herein, the Securities Administrator, on behalf of the Trust, will elect to treat the segregated pool of assets consisting of the REMIC 1 Regular Interests as a REMIC for federal income tax purposes, and such segregated pool of assets will be designated as REMIC 2. The Class R-2 Interest, beneficial ownership of which is evidenced by the Class R Certificates, will represent the sole class of “residual interests” in REMIC 2 for purposes of the REMIC Provisions under federal income tax law. The following table irrevocably sets forth the designation and Initial Class Certificate Balance for each of the “regular interests” in REMIC 2 (the “REMIC 2 Regular Interests”). The “latest possible maturity date” (determined solely for purposes of satisfying Treasury regulation Section 1.860G-1(a)(4)(iii)) for each REMIC 2 Regular Interest shall be the first Distribution Date (i.e. September 25, 2037) that follows the stated maturity date for the Mortgage Loan included in the Trust Fund as of the Closing Date with the longest remaining term to stated maturity.

¹	Solely for purposes of Section 1.860G-1(a)(4)(iii) of the Treasury regulations, the Distribution Date immediately following the stated maturity date for the Mortgage Loan with the latest maturity date has been designated as the “latest possible maturity date” for each REMIC 1 Regular Interest.

2	Calculated in accordance with the definition of “REMIC I Remittance Rate” herein.

(e) [Reserved]

(f) After the reduction of the Class Certificate Balances of the Senior Certificates of any Certificate Group to zero but prior to the Credit Support Depletion Date, the Senior Certificates shall be entitled to no further distributions of principal thereon, and the related Available Funds shall be distributed solely to the holders of the Subordinate Certificates, in each case as described herein.

(g) [Reserved]

(h) In addition to the foregoing distributions, with respect to any Subsequent Recoveries, the related Servicer shall deposit such funds into the related Collection Account. If, after taking into account such Subsequent Recoveries, the amount of a Realized Loss with respect to any Mortgage Loan is reduced, the amount of such Subsequent Recoveries will be applied to increase the Class Certificate Balance of the Class of related Subordinate Certificates with the Highest Priority to which Realized Losses for such Mortgage Loan, have been allocated, but not by more than the amount of Realized Losses with respect to such Mortgage Loan previously allocated to that Class of Certificates pursuant to Section 4.04. The amount of any remaining Subsequent Recoveries from such Mortgage Loan will be applied to increase the Class Certificate Balance of the Class of Certificates with the next Lower Priority, up to the amount of such Realized Losses previously allocated to that Class of Certificates pursuant to Section 4.04. Any remaining Subsequent Recoveries from the related Mortgage Loan will in turn be applied to increase the Class Certificate Balance of the Class of Certificates with the next Lower Priority up to the amount of such Realized Losses previously allocated to that Class of Certificates pursuant to Section 4.04, and so on. Holders of such Certificates will not be entitled to any payment in respect of Accrued Certificate Interest on the amount of such increases for any Interest Accrual Period preceding the Distribution Date on which such increase occurs.

Any such increases shall be applied to the Class Certificate Balance of each Certificate of such Class in accordance with its respective Percentage Interest.

(i) Each distribution with respect to a Book-Entry Certificate shall be paid to the Depository, as Holder thereof, and the Depository shall be solely responsible for crediting the amount of such distribution to the accounts of its Depository Participants in accordance with its normal procedures. Each Depository Participant shall be responsible for disbursing such distribution to the Certificate Owners that it represents and to each indirect participating brokerage firm (a “brokerage firm” or “indirect participating firm”) for which it acts as agent. Each brokerage firm shall be responsible for disbursing funds to the Certificate Owners that it represents. None of the Trustee, the Securities Administrator, the Sponsor, the Depositor or the Master Servicer shall have any responsibility therefor except as otherwise provided by this Agreement or applicable law.

-57-

On the first Distribution Date immediately following the expiration of the latest prepayment penalty term on the Mortgage Loans, the Securities Administrator will distribute all amounts on deposit in the Class P Reserve Fund established for the benefit of the Class P Certificates pursuant to Section 3.01(e) to the holders of the Class P Certificates, up to its Class Certificate Balance.

Section 4.03 Monthly Statements to Certificateholders. (a) Not later than each Distribution Date, the Securities Administrator shall make available to each Certificateholder, the Master Servicer, each Servicer, the Depositor, the Trustee and each Rating Agency a statement, based on information and to the extent provided by the Servicers, setting forth with respect to the related distribution:

(i) the amount thereof allocable to principal (other than with respect to the Interest Only Certificates), separately identifying the aggregate amount of any Principal Prepayments, Liquidation Proceeds and Subsequent Recoveries;

(ii) the amount thereof allocable to interest for such Distribution Date;

(iii) if the distribution to the Holders of such Class of Certificates is less than the full amount that would be distributable to such Holders if there were sufficient funds available therefor, the amount of the shortfall and the allocation thereof as between principal and interest;

(iv) the Class Certificate Balance of each Class of Certificates after giving effect to the distribution of principal on such Distribution Date;

(v) the Pool Stated Principal Balance for the following Distribution Date;

(vi) the amount of the Expense Fees (in the aggregate and separately stated) paid to or retained by the Servicers and any Subservicer with respect to such Distribution Date;

-58-

(vii) the Interest Rate for each such Class of Certificates with respect to such Distribution Date;

(viii) the amount of P&I Advances included in the distribution on such Distribution Date and the aggregate amount of P&I Advances outstanding as of the close of business on the Determination Date immediately preceding such Distribution Date;

(ix) by Loan Group, and in the aggregate, the number and aggregate outstanding principal balances of Mortgage Loans (except those Mortgage Loans that are liquidated as of the end of the related Prepayment Period) (1) as to which the Scheduled Payment is delinquent 31 to 60 days, 61 to 90 days and 91 or more days, (2) that have become REO Property, (3) that are in foreclosure and (4) that are in bankruptcy, in each case as of the close of business on the last Business Day of the immediately preceding month;

(x) by Loan Group, and in the aggregate, with respect to Mortgage Loans that became REO Properties during the preceding calendar month, the number and the aggregate Stated Principal Balance of such Mortgage Loans as of the close of business on the Determination Date preceding such Distribution Date and the date of acquisition thereof;

(xi) by Loan Group, and in the aggregate, the total number and aggregate principal balance of any REO Properties as of the close of business on the Determination Date preceding such Distribution Date;

(xv) For purposes of preparing the Monthly Statement, delinquencies shall be determined and reported by the Master Servicer based on the so-called “OTS” methodology irrespective of the method for determining delinquencies utilized by the applicable Servicer on mortgage loans similar to the Mortgage Loans. By way of example, a Mortgage Loan would be delinquent with respect to a Scheduled Payment due on a Due Date if such Scheduled Payment is not made by the close of business on the Mortgage Loan’s next succeeding Due Date, and a Mortgage Loan would be more than 30-days Delinquent with respect to such Scheduled Payment if such Scheduled Payment were not made by the close of business on the Mortgage Loan’s second succeeding Due Date.

(d) Within a reasonable period of time after March 15^th of each calendar year, the Securities Administrator shall without charge, upon written request, cause to be furnished to each Person who at any time during the calendar year was a Certificateholder, copies of the annual reports set forth in Sections 3.03 and 3.04 of this Agreement for such calendar year during which such Person was a Certificateholder.

Section 4.04 Allocation of Realized Losses. Prior to each Distribution Date, the Securities Administrator shall determine the total amount of Realized Losses, if any, based solely upon the information provided by the Servicers to the Master Servicer, that resulted from any Cash Liquidation, Servicing Modification, Deficient Valuation or REO Disposition that occurred during the related Prepayment Period or, in the case of a Servicing Modification that constitutes a reduction of the interest rate on a Mortgage Loan, the amount of the reduction in the interest portion of the Scheduled Payment due during the related Due Period. The amount of each Realized Loss shall be based solely on and evidenced by an Officer’s Certificate provided by the Servicers. With respect to all Realized Losses (i) the principal portion of Realized Losses, shall be allocated by the Securities Administrator as follows: first, to the Class B-6 Certificates until the Class Certificate Balance thereof has been reduced to zero; second, to the Class B-5 Certificates until the Class Certificate Balance thereof has been reduced to zero; third, to the Class B-4 Certificates until the Class Certificate Balance thereof has been reduced to zero; fourth, to the Class B-3 Certificates until the Class Certificate Balance thereof has been reduced to zero; fifth, to the Class B-2 Certificates until the Class Certificate Balance thereof has been reduced to zero; sixth, to the Class B-1 Certificates until the Class Certificate Balance thereof has been reduced to zero; and, thereafter, the amount of any Realized Loss on any Mortgage Loan included in any Loan Group will be allocated among all remaining classes of Senior Certificates related to that Loan Group on a pro rata basis until the Class Certificate Balances thereof have been reduced to zero, and (ii) the interest portion of Realized Losses, shall be allocated by the Securities Administrator as follows: first, to the Subordinate Certificates in reverse order of seniority, in reduction of the Accrued Certificate Interest thereon payable on the related Distribution Date and then in reduction of the Class Certificate Balance of such Subordinate Certificate, and, second, to the remaining classes of Senior Certificates related to such Loan Group on a pro rata basis until the Class Certificate Balances thereof have been reduced to zero; provided, however, that (A) such Realized Losses otherwise allocable to the Class I-A-1, Class II-A-1, Class III-A-1 and Class IV-A-1 Certificates will be allocated to the Class I-A-2, Class II-A-2, Class III-A-2 and Class IV-A-2 Certificates, respectively, until the Class Certificate Balances of the Class I-A-2, Class II-A-2, Class III-A-2 and Class IV-A-2 Certificates have been reduced to zero.

-60-

On any Distribution Date, Realized Losses will be allocated by the Securities Administrator as set forth herein after distributions of principal on the Certificates as set forth herein.

As used herein, an allocation of a Realized Loss on a “pro rata basis” among two or more specified Classes of Certificates means an allocation on a pro rata basis, among the various Classes so specified, to each such Class of Certificates on the basis of their then outstanding Certificate Balances prior to giving effect to distributions to be made on such Distribution Date in the case of the principal portion of a Realized Loss or based on the Accrued Certificate Interest thereon payable on such Distribution Date (without regard to any Compensating Interest for such Distribution Date) in the case of an interest portion of a Realized Loss. Except as provided in the following sentence, any allocation of the principal portion of Realized Losses to a Class of Certificates shall be made by reducing the Certificate Balance thereof by the amount so allocated, which allocation shall be deemed to have occurred on such Distribution Date; provided that no such reduction shall reduce the aggregate Certificate Balance of the Certificates below the aggregate Stated Principal Balance of the Mortgage Loans.

THE CERTIFICATES

Section 5.01 The Certificates. The Certificates shall be substantially in the forms attached hereto as exhibits. 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) and aggregate denominations per Class set forth in the Preliminary Statement. The Depositor hereby directs the Securities Administrator to register the Class P Certificates in the name of HSBC Securities (USA) Inc. or its designee.

Subject to Section 12.02 respecting the final distribution on the Certificates, on each Distribution Date the Securities 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 Securities Administrator at least five Business Days prior to the applicable Distribution Date or (y) by check mailed by first Class mail to such Certificateholder at the address of such holder appearing in the Certificate Register; provided, however, so long as such Certificate is a Book-Entry Certificate, all distributions on such Certificate will be made through the Depository or the Depository Participant.

-61-

The Certificates shall be executed by manual or facsimile signature on behalf of the Securities Administrator by an authorized officer. Certificates bearing the manual or facsimile signatures of individuals who were, at the time such signatures were affixed, authorized to sign on behalf of the Securities Administrator shall bind the Securities Administrator, notwithstanding that such individuals or any of them have ceased to be so authorized prior to the authentication and delivery of any 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 authenticated by the Securities Administrator by manual signature, and such authentication 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 authentication. On the Closing Date, the Securities Administrator shall authenticate the Certificates to be issued at the direction of the Depositor, or any affiliate thereof.

Section 5.02 Certificate Register; Registration of Transfer and Exchange of Certificates. (a) The Securities Administrator shall maintain, or cause to be maintained in accordance with the provisions of Section 5.06, 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 Securities 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 Securities 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 Securities Administrator. Whenever any Certificates are so surrendered for exchange, the Securities 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 Securities 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.

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

-62-

(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 determining whether a transfer is being made pursuant to an effective registration statement, the Securities Administrator shall be entitled to rely solely upon a written notice to such effect from the Depositor. In the event that a transfer of a Private Certificate which is a Physical Certificate 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 shall certify to the Securities Administrator in writing the facts surrounding the transfer in substantially the form set forth in Exhibit H (the “Transferor Certificate”) and there shall be delivered to the Securities Administrator a letter in substantially the form of Exhibit I (the “Rule 144A Investment Letter”) or (ii) there shall be delivered to the Securities Administrator at the expense of the transferor an Opinion of Counsel stating that such transfer may be made without registration under the Securities Act. For purposes of the preceding sentence, with respect to a Private Certificate that is not a Physical Certificate or a Residual Certificate, in the event the Rule 144A Investment Letter is not furnished, such representation shall be deemed to have been made to the Securities Administrator by the transferee’s (including an initial acquirer’s) acceptance of the Private Certificates. In the event that a transfer of a Private Certificate which is a Book-Entry Certificate 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 will be deemed to have made as of the transfer date each of the certifications set forth in the Transferor Certificate in respect of such Certificate and the transferee will be deemed to have made as of the transfer date each of the certifications set forth in the Rule 144A Investment Letter, in respect of such Certificate, in each case as if such Certificate were evidenced by a Physical Certificate. As directed by the Depositor, the Securities Administrator 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 Depositor, the Master Servicer and the Trustee shall cooperate with the Securities Administrator in providing the Rule 144A information referenced in the preceding sentence, including providing to the Securities Administrator such information regarding the Certificates, the Mortgage Loans and other matters regarding the Trust Fund as the Securities Administrator shall reasonably determine 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 Securities Administrator, the Trustee, each Servicer, 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 Securities Administrator shall have received either (i) a representation from the transferee of such Certificate acceptable to and in form and substance satisfactory to the Securities Administrator (in the event such Certificate is a Private Certificate or a Residual Certificate, such requirement is satisfied only by the Securities Administrator’s receipt of a representation letter from the transferee substantially in the form of Exhibit I), to the effect that such transferee is not an employee benefit plan or arrangement subject to Section 406 of ERISA, a plan subject to Section 4975 of the Code or a plan subject to any Federal, state or local law (“Similar Law”) materially similar to the foregoing provisions of ERISA or the Code, nor a person acting on behalf of any such plan or arrangement nor using the assets of any such plan or arrangement to effect such transfer, or (ii) in the case of an ERISA-Restricted Certificate (other than a Residual Certificate or the Class P Certificate) that has been the subject of an ERISA-Qualifying Underwriting, and the purchaser is an insurance company, a representation that the purchaser is an insurance company that 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 (“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) in the case of any such ERISA-Restricted Certificate other than a Residual Certificate or the Class P Certificate presented for registration in the name of an employee benefit plan subject to Title I of ERISA, a plan or arrangement subject to Section 4975 of the Code (or comparable provisions of any subsequent enactments), or a plan subject to Similar Law, or a trustee of any such plan or any other person acting on behalf of any such plan or arrangement or using such plan’s or arrangement’s assets, an Opinion of Counsel satisfactory to the Securities Administrator, which Opinion of Counsel shall not be an expense of the Depositor, the Trustee, the Master Servicer, the Servicers, the Securities Administrator or the Trust Fund, addressed to the Securities Administrator, to the effect that the purchase or holding of such ERISA-Restricted Certificate will not constitute or result in a non-exempt prohibited transaction within the meaning of ERISA, Section 4975 of the Code or any Similar Law and will not subject the Trustee, the Depositor, the Securities Administrator, the Master Servicer or any Servicer to any obligation in addition to those expressly undertaken in this Agreement or to any liability. For purposes of the preceding sentence, with respect to an ERISA-Restricted Certificate that is not a Physical Certificate or a Residual Certificate, in the event the representation letter referred to in the preceding sentence is not furnished, such representation shall be deemed to have been made to the Securities Administrator by the transferee’s (including an initial acquirer’s) acceptance of the ERISA-Restricted Certificates. Notwithstanding anything else to the contrary herein, (a) any purported transfer of an ERISA-Restricted Certificate that is a Physical Certificate or Residual Certificate or the Class P Certificate, to or on behalf of an employee benefit plan subject to ERISA, the Code or Similar Law without the delivery to the Securities Administrator of a representation letter or an Opinion of Counsel satisfactory to the Securities Administrator as described above shall be void and of no effect and (b) any purported transfer of a Residual Certificate or the Class P Certificate to a transferee that does not make the representation in clause (i) above shall be void and of no effect.

-63-

None of the Class R or Class P Certificates may be sold to any employee benefit plan subject to Title I of ERISA, any plan subject to Section 4975 of the Code, or any plan subject to any Similar Law or any person investing on behalf or with plan assets of such plan.

To the extent permitted under applicable law (including, but not limited to, ERISA), the Securities 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, in the case of a Physical Certificate, the transfer was registered by the Securities Administrator in accordance with the foregoing requirements.

-64-

(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 Securities 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 Securities Administrator shall not register the Transfer of any Residual Certificate unless, in addition to the certificates required to be delivered to the Securities Administrator under subparagraph (b) above, the Securities 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 G;

(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 a Non-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 Securities 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(a) 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 the Rule 144A Letter. The Securities Administrator shall be entitled but not obligated to recover from any Holder of a Residual Certificate that was in fact a Non-Permitted Transferee at the time it became a Holder or, at such subsequent time as it became a Non-Permitted Transferee, all payments made on such Residual Certificate at and after either such time. Any such payments so recovered by the Securities Administrator shall be paid and delivered by the Securities Administrator to the last preceding Permitted Transferee of such Certificate; and

-65-

(v) The Depositor shall use its best efforts to make available, upon receipt of written request from the Securities 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 a Non-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 Securities Administrator of an Opinion of Counsel, which Opinion of Counsel shall not be an expense of the Trust Fund, the Trustee, the Securities Administrator or any Servicer, to the effect that the elimination of such restrictions will not cause any REMIC created 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 Securities 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 a Non-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 a Non-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 Securities 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 Securities Administrator shall deal with the Depository, Depository Participants and indirect participating firms as representatives 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 representatives shall not be deemed to be inconsistent if they are made with respect to different Certificate Owners; and (vi) the Securities Administrator may 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.

-66-

If (x) (i) the Depository or the Depositor advises the Securities Administrator in writing that the Depository is no longer willing or able to properly discharge its responsibilities as Depository, and (ii) the Securities Administrator or the Depositor is unable to locate a qualified successor, or (y) the Depositor notifies the Depository (and the Securities Administrator consents) of its intent to terminate the book-entry system through the Depository and, upon receipt of notice of such intent from the Depository, the Depository Participants holding beneficial interests in the Book-Entry Certificates agree in writing to initiate such termination, the Securities Administrator 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 Securities Administrator of the related Class of Certificates by the Depository, accompanied by the instructions from the Depository for registration, the Securities Administrator shall issue the Definitive Certificates. None of the Servicers, the Depositor or the Securities 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 Securities 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 Securities Administrator, to the extent applicable with respect to such Definitive Certificates and the Securities Administrator shall recognize the Holders of the Definitive Certificates as Certificateholders hereunder; provided, that the Securities 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.

(f) Each Private Certificate presented or surrendered for registration of transfer or exchange shall be accompanied by a written instrument of transfer and accompanied by IRS Form W-8ECI, W-8BEN, W-8IMY (and all appropriate attachments) or W-9 in form satisfactory to the Securities Administrator, duly executed by the Certificateholder or his attorney duly authorized in writing. Each Certificate presented or surrendered for registration of transfer or exchange shall be canceled and subsequently disposed of by the Securities Administrator in accordance with its customary practice. No service charge shall be made for any registration of transfer or exchange of Private Certificates, but the Securities Administrator may require payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any transfer or exchange of Private Certificates.

Section 5.03 Mutilated, Destroyed, Lost or Stolen Certificates. If (a) any mutilated Certificate is surrendered to the Securities Administrator, or the Securities Administrator receives evidence to its satisfaction of the destruction, loss or theft of any Certificate and (b) there is delivered to the Depositor, the Securities Administrator and the Trustee such security or indemnity as may be required by them to hold each of them harmless, then, in the absence of notice to a Responsible Officer of the Securities Administrator that such Certificate has been acquired by a bona fide purchaser, the Securities Administrator shall execute, authenticate 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 Securities 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 Securities Administrator) 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.

-67-

Section 5.04 Persons Deemed Owners. The Trustee, the Depositor, the Securities Administrator and any agent of the Trustee, the Depositor or the Securities Administrator 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 neither the Trustee, the Depositor, the Securities Administrator nor any agent of the Trustee, the Depositor or the Securities Administrator 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 Securities 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 any Servicer shall request such information in writing from the Securities Administrator, then the Securities Administrator shall, within ten Business Days after the receipt of such request, provide the Depositor, the applicable Servicer or such Certificateholders at such recipients’ expense the most recent list of the Certificateholders of such Trust Fund held by the Securities Administrator, if any. The Depositor and every Certificateholder, by receiving and holding a Certificate, agree that the Securities 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. The Securities Administrator will maintain or cause to be maintained at its expense an office or offices or agency or agencies where Certificates may be surrendered for registration of transfer or exchange.

Notwithstanding the foregoing, if the Master Servicer or the Trustee (as successor master servicer), as applicable, has become the successor to a Servicer pursuant to an Event of Default, the Master Servicer or the Trustee (as successor master servicer), as applicable, may, if it shall be unwilling to so act, or shall, if it is prohibited by applicable law from making P&I Advances and Servicing Advances pursuant to the applicable Servicing Agreement, if it is otherwise unable to so act, or at the written request of Certificateholders entitled to at least a majority of the Voting Rights, 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 Servicer under the applicable Servicing Agreement in the assumption of all or any part of the responsibilities, duties or liabilities of such Servicer thereunder.

-70-

(c) Any successor to a Servicer shall be an institution which is willing to service the Mortgage Loans, having a net worth of not less than $25,000,000, and which executes and delivers to the Depositor, the Master Servicer and the Trustee (as successor master servicer) an agreement accepting such delegation and assignment, containing an assumption by such Person of the rights, powers, duties, responsibilities, obligations and liabilities of the applicable Servicer (other than liabilities of the predecessor servicer incurred prior to its termination), with like effect as if originally named as a party to such Servicing Agreement; provided, 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 a Servicer under any Servicing Agreement, the Master Servicer or the Trustee (as successor master servicer), as applicable, unless such party is prohibited by law from so acting, shall act in such capacity as hereinabove provided. In connection with such appointment and assumption, the Master Servicer or the Trustee (as successor master servicer), as applicable, may make such arrangements for the compensation of such successor out of payments on Mortgage Loans as it and such successor shall agree in accordance with the applicable Servicing Agreement; provided, however, that no such compensation shall be in excess of the applicable Servicing Fee and any income on investments or gain related to the related Collection Account. The Master Servicer or the Trustee (as successor master servicer), as applicable, and such successor servicer shall take such action, consistent with this Agreement and the applicable Servicing Agreement, as shall be necessary to effectuate any such succession. Neither the Master Servicer nor the Trustee (as 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 any Servicer to deliver or provide, or any delay in delivering or providing, any cash, information, documents or records to it.

(d) Notwithstanding the foregoing, the parties hereto agree that the Master Servicer or the Trustee (as successor master servicer), as applicable, in its capacity as successor servicer, immediately shall assume all of the obligations of such terminated Servicer to make Advances and the Master Servicer or the Trustee (as successor master servicer), as applicable, will assume the other duties of such Servicer as soon as practicable, but in no event later than 90 days after the Master Servicer or the Trustee (as successor master servicer), as applicable, becomes successor servicer pursuant to the preceding paragraph. If the Master Servicer or the Trustee (as successor master servicer), as applicable, acts as a successor servicer, it will have no obligation to make an Advance if it determines in its reasonable judgment that such Advance is non-recoverable. To the extent that the Master Servicer or the Trustee (as successor master servicer) is unable to find a successor servicer that is willing to service the Mortgage Loans for the Servicing Fee because of the obligation of the applicable Servicer to make Advances regardless of whether such Advance is recoverable, the applicable Servicing Agreement may be amended to provide that the successor servicer shall have no obligation to make an Advance if it determines in its reasonable judgment that such Advance is non-recoverable and provides an Officer’s Certificate to such effect to the Master Servicer and the Trustee. Notwithstanding the foregoing, the Master Servicer or the Trustee (as successor master servicer), as applicable, in its capacity as successor servicer, shall not be responsible for the lack of information and/or documents that it cannot obtain through reasonable efforts; provided, however, that any failure to perform any duties or responsibilities caused by such Servicer’s failure to provide information required by this Agreement shall not be considered a default by the Trustee (as successor master servicer) hereunder. In the Trustee’s capacity as such successor, the Trustee (as successor master servicer) shall have the same limitations on liability granted to the Servicer under this Agreement and the related Servicing Agreement.

-71-

(e) In the event that the Master Servicer or the Trustee (as successor master servicer), as applicable, is the terminated Servicer (except in the case where the Master Servicer in its role as successor servicer is being terminated pursuant to an Event of Default caused solely by the Master Servicer as the successor servicer and not by the predecessor Servicer’s actions or omissions), such costs shall be paid by such prior terminated Servicer promptly upon presentation of reasonable documentation of such costs.

Section 7.02 Notification to Certificateholders. (a) Upon any termination of or appointment of a successor to any Servicer, the Securities Administrator shall give prompt written notice thereof to Certificateholders and each Rating Agency.

(b) Within 60 days after the occurrence of any Event of Default the Trustee shall provide written direction to the Securities Administrator instructing the Securities Administrator to distribute (and upon receipt of such direction the Securities Administrator shall distribute) notice to all Certificateholders and each Rating Agency of each such Event of Default hereunder known to the Trustee, unless such event shall have been cured or waived.

ARTICLE VIII

(f) 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 indemnity satisfactory to it against such risk or liability is not assured to it;

(g) the Trustee shall not be liable for any loss on any investment of funds pursuant to this Agreement;

(h) unless a Responsible Officer of the Trustee has actual knowledge of the occurrence of a Master Servicer Event of Default or an Event of Default, the Trustee shall not be deemed to have knowledge of a Master Servicer Event of Default or an Event of Default until a Responsible Officer of the Trustee shall have received written notice thereof;

(i) 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 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; and

(j) if the Trustee, in its role as successor master servicer under this Agreement, assumes the servicing or master servicing with respect to any of the Mortgage Loans, it shall not assume liability for the representations and warranties of any Servicer or the Master Servicer, as applicable, or for any errors or omissions of any Servicer or the Master Servicer, as applicable.

Section 8.05 Trustee’s Fees Indemnification and Expenses. (a) As compensation for its activities under this Agreement, the Trustee shall be paid its fee by the Securities Administrator from the Securities Administrator’s own funds pursuant to a separate agreement. The Trustee shall have no lien on the Trust Fund for the payment of such fees.

(iii) the performance of any of the Trustee’s duties under this Agreement or any Servicing Agreement (including, but not limited to, its execution of any tax returns),

other than any loss, liability, or expense (i) resulting from any breach of a Servicer’s obligations in connection with its respective Servicing Agreement for which such Servicer has performed its obligation to indemnify the Trustee, (ii) resulting from any breach of a Mortgage Loan Seller’s obligations in connection with its respective Transfer Agreement for which such Mortgage Loan Seller has performed its obligation to indemnify the Trustee, (iii) resulting from any breach of the Master Servicer’s obligation hereunder for which the Master Servicer has performed its obligation to indemnify the Trustee pursuant to this Agreement or (iv) incurred because of willful misconduct, bad faith, or negligence in the performance of any of the Trustee’s duties under this Agreement or any Servicing Agreement. Without limiting the foregoing, except as otherwise agreed upon in writing by the Depositor and the Trustee, and except for any expense, disbursement, or advance arising from the Trustee’s negligence, bad faith, or willful misconduct, the Trust Fund shall pay or reimburse the Trustee for all reasonable expenses, disbursements, and advances incurred or made by the Trustee in accordance with this Agreement with respect to:

The Trustee shall not be (a) liable for any acts or omissions of any Servicer (other than where the Trustee (as successor master servicer) is such Servicer), (b) obligated to make any Advance if it is prohibited from doing so under applicable law, (c) responsible for expenses of any Servicer (other than where the Trustee (as successor master servicer) is such Servicer) pursuant to the terms a Servicing Agreement, (d) liable for any amount necessary to induce any successor servicer to act as successor servicer under a Servicing Agreement and enter into the transactions set forth or provided for therein.

Section 8.06 Eligibility Requirements for the Trustee. The Trustee hereunder shall at all times be a corporation or association organized and doing business under the laws of a state or the United States of America, authorized under such laws to exercise corporate trust powers, having a combined capital and surplus of at least $50,000,000, subject to supervision or examination by federal or state authority and with a credit rating which would not cause any of the Rating Agencies to reduce their respective then current ratings of the Certificates (or having provided such security from time to time as is sufficient to avoid such reduction) as evidenced in writing by each Rating Agency. If such corporation or association publishes reports of condition at least annually, pursuant to law or to the requirements of the aforesaid supervising or examining authority, then for the purposes of this Section 8.06 the combined capital and surplus of such corporation or association shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. In case at any time the Trustee shall cease to be eligible in accordance with this Section 8.06, the Trustee shall resign immediately in the manner and with the effect specified in Section 8.07. The entity serving as Trustee may have normal banking and trust relationships with the Depositor and its affiliates, the Master Servicer, the Securities Administrator or the Servicers and their respective affiliates; provided, however, that such entity cannot be an affiliate of the Depositor or a Servicer other than the Trustee in its role as successor to the Master Servicer.

Section 8.07 Resignation and Removal of the Trustee. The Trustee may at any time resign and be discharged from the trusts hereby created by giving written notice of resignation to the Depositor, the Master Servicer, the Securities Administrator and each Rating Agency not less than 60 days before the date specified in such notice, when, subject to Section 8.08, such resignation is to take effect and acceptance by a successor trustee in accordance with Section 8.08 meeting the qualifications set forth in Section 8.06. If no successor trustee meeting such qualifications shall have been so appointed and have accepted appointment within 30 days after the giving of such notice or resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor trustee.

-76-

If at any time the Trustee shall cease to be eligible in accordance with Section 8.06 and shall fail to resign after written request thereto by the Depositor, or if at any time the Trustee shall become incapable of acting, or shall be adjudged as bankrupt or insolvent, or a receiver of the Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, or a tax is imposed with respect to the Trust Fund by any state in which the Trustee or the Trust Fund is located and the imposition of such tax would be avoided by the appointment of a different trustee, then the Depositor may remove the Trustee and, subject to the approval of the Rating Agencies, appoint a successor trustee by written instrument, one copy of which shall be delivered to the Trustee, one copy of which shall be delivered to the Master Servicer, one copy of which shall be delivered to each Servicer and one copy of which shall be delivered to the successor trustee.

The successor trustee shall notify each Rating Agency of any removal of the Trustee.

Any resignation or removal of the Trustee and appointment of a successor trustee pursuant to this Section 8.07 shall become effective upon acceptance of appointment by the successor trustee as provided in Section 8.08.

Any successor trustee appointed as provided in Section 8.07 shall execute, acknowledge and deliver to the Depositor and to its predecessor trustee and each Servicer an instrument accepting such appointment hereunder and thereupon the resignation or removal of the predecessor trustee shall become effective and such successor trustee, without any further act, deed or conveyance, shall become fully vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as trustee herein. The Depositor and the predecessor trustee shall execute and deliver such instruments and do such other things as may reasonably be required for more fully and certainly vesting and confirming in the successor trustee all such rights, powers, duties, and obligations.

No successor trustee shall accept appointment as provided in this Section 8.08 unless at the time of its acceptance, the successor trustee is eligible under Section 8.06 and its appointment does not adversely affect then the current rating of the Certificates.

-77-

Upon acceptance of appointment by a successor trustee as provided in this Section 8.08, the Depositor shall mail notice of the succession of such trustee hereunder to all Holders of Certificates. If the Depositor fails to mail such notice within 10 days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be mailed at the expense of the Depositor.

Section 8.09 Merger or Consolidation of the Trustee. Any corporation into which the Trustee may be merged or converted or with which it may be consolidated or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to the business of the Trustee, shall be the successor of the Trustee hereunder; provided, that such corporation shall be eligible under Section 8.06 without the execution or filing of any paper or further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding.

Section 8.10 Appointment of Co-Trustee or Separate Trustee. Notwithstanding any other provisions of this Agreement, at any time, for the purpose of meeting any legal requirements of any jurisdiction in which any part of the Trust Fund or property securing any Mortgage Note may at the time be located, the Trustee shall have the power and shall execute and deliver all instruments to appoint one or more Persons approved by the Trustee to act as co-trustee or co-trustees jointly with the Trustee, or separate trustee or separate trustees, of all or any part of the Trust Fund, and to vest in such Person or Persons, in such capacity and for the benefit of the Certificateholders, such title to the Trust Fund or any part thereof, whichever is applicable, and, subject to the other provisions of this Section 8.10, such powers, duties, obligations, rights and trusts as the Trustee may consider appropriate. 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:

(a) To the extent necessary to effectuate the purposes of this Section 8.10, all rights, powers, duties and obligations conferred or imposed upon the Trustee, except for the obligation of the Trustee (as successor master servicer) under this Agreement to advance funds on behalf of the Master Servicer, shall be conferred or imposed upon and exercised or performed by the Trustee and such separate trustee or co-trustee jointly (it being understood that such separate trustee or co-trustee is not authorized to act separately without the Trustee joining in such act), except to the extent that under any law of any jurisdiction in which any particular act or acts are to be performed (whether as Trustee hereunder or as successor to the Master Servicer hereunder), the Trustee shall be incompetent or unqualified to perform such act or acts, in which event such rights, powers, duties and obligations (including the holding of title to the applicable Trust Fund or any portion thereof in any such jurisdiction) shall be exercised and performed singly by such separate trustee or co-trustee, but solely at the direction of the Trustee;

(b) No trustee hereunder shall be held personally liable because 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;

-78-

(d) The Trust Fund, and not the Trustee, shall be liable for the payment of reasonable compensation, reimbursement and indemnification to any such 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 and indemnity 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.

Section 8.11 [Reserved].

Section 8.12 Commission Reporting. (a) The Securities Administrator shall, in accordance with industry standards, prepare and file with the Commission, via ▇▇▇▇▇, the following reports in respect of the Trust as and to the extent required under the Exchange Act:

(i) (a) Within 15 days after each Distribution Date (subject to permitted extensions under the Exchange Act), the Securities Administrator shall prepare and file on behalf of the Trust any Form 10-D required by the Exchange Act, in form and substance as required by the Exchange Act. The Securities Administrator shall file each Form 10-D with a copy of the related Monthly Statement attached thereto. Any disclosure in addition to the Monthly Statement that is required to be included on Form 10-D (“Additional Form 10-D Disclosure”) shall be reported by the parties set forth on Exhibit V to the Depositor and the Securities Administrator and directed and approved by the Depositor pursuant to the following paragraph and the Securities Administrator will have no duty or liability for the inaccuracy of any Additional 10 D Disclosure provided by any party other than the Securities Administrator, or for any failure hereunder to determine or prepare any Additional Form 10-D Disclosure, except to the extent of its obligations set forth in the next paragraph.

(b) As set forth on Exhibit V hereto, within 5 calendar days after the related Distribution Date, (i) the parties specified in Exhibit V hereto, shall be required to provide to the Securities Administrator and to the Depositor, to the extent known, in ▇▇▇▇▇-compatible format, or in such other format as agreed upon by the Securities Administrator and such party, the form and substance of any Additional Form 10-D Disclosure, if applicable, together with an Additional Disclosure Notification, and (ii) the Depositor will approve, as to form and substance, or disapprove, as the case may be, the inclusion of the Additional Form 10-D Disclosure on Form 10-D. The Securities Administrator has no duty under this Agreement to monitor or enforce the performance by the parties listed on Exhibit V of their duties under this paragraph or proactively solicit or procure from such parties any Additional Form 10-D Disclosure information. The Depositor shall be responsible for any reasonable fees and expenses assessed or incurred by the Securities Administrator in connection with including any Additional Form 10-D Disclosure on Form 10-D pursuant to this paragraph.

-79-

(c) After preparing the Form 10-D, the Securities Administrator shall, upon request, forward electronically a copy of the Form 10-D to the Depositor (provided that such Form 10-D includes any Additional Form 10-D Disclosure). Within two Business Days after receipt of such copy, but no later than the 12^th calendar day after the Distribution Date, the Depositor shall notify the Securities Administrator in writing (which may be furnished electronically) of any changes to or approval of such Form 10-D. In the absence of receipt of any written changes or approval, or if the Depositor does not request a copy of a Form 10-D, the Securities Administrator shall be entitled to assume that such Form 10-D is in final form and the Securities Administrator may proceed with the process for execution and filing of the Form 10-D. A duly authorized representative of the Master Servicer shall sign each Form 10-D. If a Form 10-D cannot be filed on time or if a previously filed Form 10-D needs to be amended, the Securities Administrator will follow the procedures set forth in paragraph (d) of this Section 8.12. Promptly (but no later than one Business Day) after filing with the Commission, the Securities Administrator will make available on its internet website (located at ▇▇▇.▇▇▇▇▇▇▇.▇▇▇) a final executed copy of each Form 10-D prepared and filed by the Securities Administrator. Each party to this Agreement acknowledges that the performance by each of the Master Servicer and the Securities Administrator of its duties under this Section 8.12(a)(i) 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 8.12(a)(i). The Depositor acknowledges that the performance by each of the Master Servicer and the Securities Administrator of its duties under this Section 8.12(i) related to the timely preparation, execution and filing of Form 10-D is also contingent upon any Servicing Function Participant strictly observing deadlines no later than those set forth in this paragraph that are applicable to the parties to this Agreement in the delivery to the Securities Administrator of any necessary Additional Form 10-D Disclosure pursuant to any applicable agreement. Neither the Master Servicer nor the Securities Administrator shall have any liability for any loss, expense, damage, 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 Securities Administrator’s inability or failure to receive, on a timely basis, any information from any other party hereto or any Servicing Function Participant needed to prepare, arrange for execution or file such Form 10-D, not resulting from its own negligence, bad faith or willful misconduct.

-80-

-82-

Promptly, but no later than the close of business on the third Business Day after the Reportable Event, the Depositor shall notify the Securities Administrator in writing (which may be furnished electronically) of any changes to or approval of such Form 8-K. In the absence of receipt of any written changes or approval, or if the Depositor does not request a copy of a Form 8-K, the Securities Administrator shall be entitled to assume that such Form 8-K is in final form and the Securities Administrator may proceed with the process for execution and filing of the Form 8-K.

The Securities Administrator shall have no liability for any loss, expense, damage, claim arising out of or with respect to any failure to properly prepare and/or timely file such Form 8-K, where such failure results from the Securities Administrator’s inability or failure to obtain or receive, on a timely basis, any information from any other party hereto or any Servicing Function Participant needed to prepare, arrange for execution or file such Form 8-K, not resulting from its own negligence, bad faith or willful misconduct.

-84-

(b) The Depositor acknowledges and agrees that the Securities Administrator may include in any Exchange Act report all relevant information, data, and exhibits as the Securities Administrator may receive in connection with such report irrespective of any provision or Regulation AB that may permit the exclusion of such material. By the way of example, the Securities Administrator may file all assessments of compliance, attestation reports and compliance statements timely received from any Item 1122 Servicing Function Participant irrespective of any applicable minimum pool asset percentage requirement for disclosure related to such Servicing Function Participant.

(c) The Depositor agrees to furnish promptly to the Securities Administrator, from time to time upon request, such additional information, data, reports, documents, and financial statements within the Depositor’s possession or control as the Securities Administrator reasonably requests as necessary or appropriate to prepare and file the foregoing reports.

(ii) In the event that the Securities Administrator is unable to timely file with the Commission all or any required portion of any Form 8-K, 10-D or 10-K required to be filed by this Agreement because required disclosure information was either not delivered to it or delivered to it after the delivery deadlines set forth in this Agreement or for any other reason, the Securities Administrator will promptly notify electronically the Depositor.

In the case of Form 8-K, the Securities Administrator will, upon receipt of all required Form 8-K Disclosure Information and upon the approval and direction of the Depositor, include such disclosure information on the next Form 10-D. In the event that any previously filed Form 8-K, 10-D or 10-K needs to be amended in connection with any Additional Form 10-D Disclosure (other than, in the case of Form 10-D, for the purpose of restating any Monthly Statement), Additional Form 10-K Disclosure or Form 8-K Disclosure Information, the Securities Administrator will notify electronically the Depositor and such other parties to this Agreement as are affected by this Amendment and such parties will cooperate to prepare any necessary 8-KA, 10-DA or 10-KA. Any Form 15, Form 12b-25 or any amendment to Form 8-K, 10-D or 10-K shall be signed by a duly authorized representative or senior officer in charge of master servicing, as applicable, of the Master Servicer. The parties to this Agreement acknowledge that the performance by each of the Master Servicer and the Securities Administrator of its duties under this Section 8.12(d) related to the timely preparation, execution and filing of Form 15, a Form 12b-25 or any amendment to Form 8-K, 10-D or 10-K is contingent upon each such party performing its duties under this Section.

The Depositor shall be responsible for all costs and expenses of the Securities Administrator related to the preparation and filing of any such amendment. Notwithstanding the foregoing, if any Form 10-D needs to be amended solely to change the information contained in the Monthly Statement, the Securities Administrator shall not be required to notify the Depositor of such amendment.

-85-

(e) Other than the Exchange Act reports specified above, the Securities Administrator shall have no responsibility to file any items or reports with the Commission under the Exchange Act or otherwise; provided, however, the Securities Administrator and Master Servicer will cooperate with the Depositor in connection with any additional filings with respect to the Trust as the Depositor deems necessary under the Exchange Act.

(f) The Depositor shall pay all costs and expenses of the Securities Administrator related to the preparation and filing of any current report on Form 8-K, any periodic report on Form 10-D (other than the costs and expense of the Securities Administrator associated with the preparation and filing of the Monthly Statement), or any amendment to any Exchange Act report. Except as otherwise provided herein, all expenses incurred by the Securities Administrator in connection with its preparation and filing of Exchange Act reports hereunder shall not be reimbursable from the Trust.

ADMINISTRATION OF THE MORTGAGE LOANS

BY THE MASTER SERVICER

Section 9.01 Duties of the Master Servicer; Enforcement of Each Servicer’s Obligations. (a) The Master Servicer, on behalf of the Trustee, the Securities Administrator, the Depositor and the Certificateholders, shall monitor the performance of the obligations of each Servicer under its respective Servicing Agreement, and (except as set forth below) shall use its reasonable good faith efforts to cause each Servicer to duly and punctually perform its duties and obligations under its respective Servicing Agreement. Upon the occurrence of an Event of Default of which a Responsible Officer of the Master Servicer or, if the Master Servicer and the applicable Servicer are the same entity, the Trustee, has actual knowledge, the Master Servicer or the Trustee, as applicable, shall promptly notify the Securities Administrator and the Trustee, as applicable, and shall specify in such notice the action, if any, the Master Servicer or the Trustee, as applicable, plans to take in respect of such default. So long as an Event of Default shall occur and be continuing, the Master Servicer or the Trustee, as applicable, shall take the actions specified in Article VII.

-86-

If (i) a Servicer reports a delinquency on a monthly report and (ii) such Servicer, by 11 a.m. (New York Time) on the related Remittance Date, neither makes an Advance nor provides the Securities Administrator, the Master Servicer and the Trustee with an Officer’s Certificate certifying that such an Advance would be a Nonrecoverable P&I Advance or Nonrecoverable Servicing Advance, then the Master Servicer or, if the Master Servicer and such Servicer are the same entity, the Trustee, shall deposit in the Distribution Account not later than the Business Day immediately preceding the related Distribution Date an Advance in an amount equal to the difference between (x) with respect to each Monthly Payment due on a Mortgage Loan that is delinquent (other than Relief Act Interest Shortfalls) and for which the related Servicer was required to make an Advance pursuant to the related Servicing Agreement and (y) amounts deposited in the related Collection Account to be used for Advances with respect to such Mortgage Loan, except to the extent the Master Servicer or the Trustee, as applicable, determines any such Advance to be a Nonrecoverable P&I Advance or Nonrecoverable Servicing Advance. Subject to the foregoing and Section 7.01, the Master Servicer or the Trustee, as applicable, shall continue to make such Advances for so long as the applicable Servicer is required to do so under its respective Servicing Agreement. If applicable, on the Business Day immediately preceding the Distribution Date, the Master Servicer shall deliver an Officer’s Certificate to the Trustee 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 P&I Advance or Nonrecoverable Servicing Advance. Any amounts deposited by the Master Servicer or the Trustee, as applicable, pursuant to this Section 9.01 shall be net of the Servicing Fee for the related Mortgage Loans.

(b) The Master Servicer or the Trustee (as successor master servicer), as applicable, shall pay the costs of monitoring the Servicers (including costs associated with (i) termination of any Servicer, (ii) the appointment of a successor servicer or (iii) the transfer to and assumption of the servicing by the Master Servicer or the Trustee, as applicable) and shall, to the extent permitted under the related Servicing Agreement, seek reimbursement therefor initially from the terminated Servicer. In the event the full costs associated with the transition of servicing responsibilities to the Master Servicer or the Trustee (as successor master servicer), as applicable, are not paid for by the predecessor or successor servicer (provided such successor servicer is not the Master Servicer or the Trustee (as successor master servicer)), the Master Servicer or the Trustee, as applicable, may be reimbursed therefor by the Trust for all costs incurred by the Master Servicer or the Trustee (as successor master servicer), as applicable, associated with any such transfer of servicing duties from the applicable Servicer to the Master Servicer or the Trustee, as applicable, or any other successor servicer.

(c) If the Master Servicer or the Trustee (as successor master servicer), as applicable, assumes the servicing with respect to any of the Mortgage Loans, it will not assume liability for the representations and warranties of the applicable Servicer it replaces or for any errors or omissions of such Servicer.

-87-

(d) Neither the Depositor nor the Securities Administrator shall consent to the assignment by any Servicer of such Servicer’s rights and obligations under that Servicer’s Servicing Agreement without the prior written consent of the Master Servicer and the Trustee, which consent shall not be unreasonably withheld.

Section 9.02 Provision to the Securities Administrator of Loan-Level Information. If the Master Servicer and the Securities Administrator are different Persons, not later than three Business Days preceding each Distribution Date, the Master Servicer shall deliver to the Securities Administrator, in a format mutually agreed upon by the Master Servicer and the Securities Administrator, “loan level’ information with respect to the Mortgage Loans as of the related Determination Date, to the extent that such information has been provided to the Master Servicer by the Servicers.

Section 9.03 [Reserved].

Section 9.04 Maintenance of Fidelity Bond and Errors and Omissions Insurance.

The errors and omissions insurance policy and the fidelity bond shall be in such form and amount generally acceptable for entities serving as master servicers or trustees.

Section 9.05 Representations and Warranties of the Master Servicer. (a) The Master Servicer hereby represents and warrants to the Depositor, the Securities Administrator and the Trustee, for the benefit of the Certificateholders, as of the Closing Date that:

It is understood and agreed that the enforcement of the obligation of the Master Servicer set forth in this Section 9.05 to indemnify the Depositor, Securities Administrator (to the extent the Master Servicer and Securities Administrator are not the same entity), the Trustee and the Trust constitutes the sole remedy of the Depositor and the Trustee, respecting a breach of the foregoing representations and warranties.

-89-

Any cause of action against the Master Servicer relating to or arising out of the breach of any representations and warranties made in this Section 9.05 shall accrue upon discovery of such breach by either the Depositor, the Master Servicer, the Securities Administrator or the Trustee or notice thereof by any one of such parties to the other parties.

Section 9.08 Successor to the Master Servicer. Upon termination of the Master Servicer’s responsibilities and duties under this Agreement, the Depositor shall use its reasonable good faith efforts to appoint a successor, which shall succeed to all rights and assume all of the responsibilities, duties and liabilities of the Master Servicer under this Agreement prior to the termination of the Master Servicer. Any successor shall be a ▇▇▇▇▇▇ ▇▇▇ and ▇▇▇▇▇▇▇ Mac approved servicer in good standing and acceptable to the Depositor and the Rating Agencies. In connection with such appointment and assumption, the Depositor may make such arrangements for the compensation of such successor as it and such successor shall agree; provided, however, that in no event shall the master servicing fee paid to such successor master servicer be in excess of the prevailing market rate at the time that the successor master servicer is appointed. In the event that the Master Servicer’s duties, responsibilities and liabilities under this Agreement are terminated, the Master Servicer shall continue to discharge its duties and responsibilities hereunder until the effective date of such termination with the same degree of diligence and prudence which it is obligated to exercise under this Agreement and shall take no action whatsoever that might impair or prejudice the rights of its successor. The termination of the Master Servicer shall not become effective until a successor shall be appointed pursuant hereto and shall in no event (i) relieve the Master Servicer of responsibility for the representations and warranties made pursuant to Section 9.05(a) hereof and the remedies available to the Trustee under Section 9.05(b) hereof, it being understood and agreed that the provisions of Section 9.05 hereof shall be applicable to the Master Servicer notwithstanding any such sale, assignment, resignation or termination of the Master Servicer or the termination of this Agreement; or (ii) affect the right of the Master Servicer to receive payment and/or reimbursement of any amounts accruing to it hereunder prior to the date of termination (or during any transition period in which the Master Servicer continues to perform its duties hereunder prior to the date the successor master servicer fully assumes its duties).

If no successor master servicer has accepted its appointment within 90 days of the time the Trustee receives the resignation of the Master Servicer, the Trustee shall be the successor master servicer in all respects under this Agreement and shall have all the rights and powers and be subject to all the responsibilities, duties and liabilities relating thereto, including the obligation to make Advances; provided, however, that any failure to perform any duties or responsibilities caused by the Master Servicer’s failure to provide information required by this Agreement shall not be considered a default by the Trustee hereunder. In the Trustee’s capacity as such successor, the Trustee shall have the same limitations on liability herein granted to the Master Servicer. Notwithstanding anything herein to the contrary, the Trustee in its role as successor master servicer shall have no obligation to monitor or supervise any Servicer, shall only have the obligation to make Advances if it terminates the Servicer pursuant to an Event of Default (in its role as successor master servicer), and shall make such Advances only pursuant to Section 7.01. As compensation therefor, the Trustee shall be entitled to receive the compensation, reimbursement and indemnities otherwise payable to the Master Servicer.

Any successor master servicer appointed as provided herein, shall execute, acknowledge and deliver to the Master Servicer, the Depositor and to the Trustee an instrument accepting such appointment, wherein the successor shall make the representations and warranties set forth in Section 9.05 hereof, and whereupon such successor shall become fully vested with all of the rights, powers, duties, responsibilities, obligations and liabilities of the Master Servicer, with like effect as if originally named as a party to this Agreement. Any termination or resignation of the Master Servicer or termination of this Agreement shall not affect any claims that the Trustee may have against the Master Servicer arising out of the Master Servicer’s actions or failure to act prior to any such termination or resignation or in connection with the Trustee’s assumption of such obligations, duties and responsibilities.

Upon a successor’s acceptance of appointment as such, the successor master servicer shall notify by mail the Trustee, the Securities Administrator and the Depositor of its appointment.

Notice of such permitted assignment shall be given promptly by the Master Servicer to the Depositor and the Trustee. If, pursuant to any provision hereof, the duties of the Master Servicer are transferred to a successor master servicer, the entire compensation payable to the Master Servicer pursuant hereto shall thereafter be payable to such successor master servicer but in no event shall the fee payable to the successor master servicer exceed that payable to the predecessor master servicer.

In such event, the legal expenses and costs of such action and any liability resulting therefrom, shall be liabilities of the Trust, and the Master Servicer shall be entitled to be reimbursed therefor out of the Distribution Account in accordance with the provisions of Section 9.14.

Section 9.14 Indemnification; Third Party Claims. The Master Servicer agrees to indemnify and hold harmless the Trustee as successor master servicer from and against any and all claims, losses, penalties, fines, forfeitures, legal fees and related costs, judgments, and any other costs, liabilities, fees and expenses (including, but not limited to, reasonable attorneys’ fees) that the Trustee may sustain as a result of such liability or obligations of the Master Servicer and in connection with the Trustee’s assumption (not including the Trustee’s performance, except to the extent that costs or liability of the Trustee are created or increased as a result of negligent or wrongful acts or omissions of the Master Servicer prior to its replacement as Master Servicer) of the Master Servicer’s obligations, duties or responsibilities under such agreement.

(j) None of the Master Servicer, the Securities Administrator or the Trustee shall (subject to Section 11.01(f)) enter into any arrangement by which any REMIC created hereunder will receive a fee or other compensation for services nor permit either REMIC to receive any income from assets other than “qualified mortgages” as defined in Section 860G(a)(3) of the Code or “permitted investments” as defined in Section 860G(a)(5) of the Code.

Section 13.03 Governing Law. THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE SUBSTANTIVE LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED IN THE STATE OF NEW YORK AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HERETO AND THE CERTIFICATEHOLDERS SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.

Section 13.04 Intention of Parties. (a) It is intended that the conveyance of the Depositor’s right, title and interest in and to property constituting the Trust Fund pursuant to this Agreement shall constitute, and shall be construed as, a sale of such property and not a grant of a security interest to secure a loan. However, if such conveyance is deemed to be in respect of a loan, it is intended that: (1) the rights and obligations of the parties shall be established pursuant to the terms of this Agreement; (2) the Depositor hereby grants to the Trustee for the benefit of the Holders of the Certificates a first priority security interest to secure repayment of an obligation in an amount equal to the aggregate Class Certificate Balances of the Certificates in all of the Depositor’s right, title and interest in, to and under, whether now owned or hereafter acquired, in all proceeds of any and all property constituting the Trust Fund to secure payment of the Certificates; and (3) this Agreement shall constitute a security agreement under applicable law. If such conveyance is deemed to be in respect of a loan and the trust created by this Agreement terminates prior to the satisfaction of the claims of any Person holding any Certificate, the security interest created hereby shall continue in full force and effect and the Trustee shall be deemed to be the collateral agent for the benefit of such Person, and all proceeds shall be distributed by the Securities Administrator as herein provided.

(b) The Depositor shall, to the extent consistent with this Agreement, take such reasonable actions as may be necessary to ensure that, if this Agreement were deemed to create a security interest in the Mortgage Loans and the other property described above, such security interest would be deemed to be a perfected security interest of first priority under applicable law and shall be maintained as such throughout the term of this Agreement. The Depositor shall, at its own expense, make all initial filings on or about the Closing Date and shall forward a copy of such filing or filings to the Trustee. Without limiting the generality of the foregoing, the Depositor shall prepare and forward for filing, or shall cause to be forwarded for filing, at the expense of the Depositor, all filings necessary to maintain the effectiveness of any original filings necessary under the relevant UCC to perfect the Trustee’s security interest in or lien on the Mortgage Loans, including without limitation (x) continuation statements, and (y) such other statements as may be occasioned by (1) any change of name of the Sponsor, the Depositor or the Trustee, (2) any change of location of the jurisdiction of organization of the Sponsor or the Depositor, (3) any transfer of any interest of the Sponsor or the Depositor in any Mortgage Loan or (4) any change under the relevant UCC or other applicable laws. Neither the Sponsor nor the Depositor shall organize under the law of any jurisdiction other than the State under which each is organized as of the Closing Date (whether changing its jurisdiction of organization or organizing under an additional jurisdiction) without giving 30 days prior written notice of such action to its immediate and intermediate transferee, including the Trustee. Before effecting such change, the Sponsor or the Depositor proposing to change its jurisdiction of organization shall prepare and file in the appropriate filing office any financing statements or other statements necessary to continue the perfection of the interests of its immediate and intermediate transferees, including the Trustee, in the Mortgage Loans. In connection with the transactions contemplated by this Agreement, each of the Sponsor and the Depositor authorizes its immediate or intermediate transferee to file in any filing office any initial financing statements, any amendments to financing statements, any continuation statements, or any other statements or filings described in this paragraph (b).

Mortgage Pass-Through Certificates

This Certificate is one of a duly authorized issue of Certificates designated as HSI Asset Loan Obligation Trust 2007-AR2 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 neither the Trustee nor the Securities Administrator is 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 Trustee.

Pursuant to the terms of the Agreement, a distribution will be made on the 25th day of each month or, if such 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. The Class [I-A- [ ]] Certificates have no Class Certificate Balance.]

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 Securities 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 offices designated by the Securities Administrator for such purposes 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 Trustee and the rights of the Certificateholders under the Agreement at any time by the parties to the Agreement 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.

EXHIBIT A-5

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 Securities Administrator upon surrender of this Certificate for registration of transfer at the offices designated by the Securities Administrator for such purposes, accompanied by a written instrument of transfer in form satisfactory to the Securities Administrator 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 Securities Administrator may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

The Trustee, the Depositor, the Master Servicer and the Securities Administrator and any agent of the Trustee, the Depositor, the Master Servicer or the Securities Administrator may treat the Person in whose name this Certificate is registered as the owner hereof for all purposes, and none of the Trustee, the Depositor, the Master Servicer, the Securities Administrator nor any such agent shall be affected by any notice to the contrary.

The Master Servicer, at its own discretion, shall purchase the Mortgage Loans and therefore cause the termination of the Trust on any Optional Termination Date, which is any Distribution Date in which the aggregate Stated Principal Balance of the Mortgage Loans as of the last day of the related Due Period is less than or equal to 10% of the aggregate Stated Principal Balance of the Mortgage Loans as of the Cut-off Date.

The obligations and responsibilities created by the Agreement will terminate as provided in Section 12.01 of 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.
