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.

The following table irrevocably sets forth the designation, the REMIC 1 Remittance Rate, the initial Uncertificated Principal Balance, and 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.

1	Approximate. Subject to variance of plus or minus 5%.

2	Interest only certificates that will accrue interest on a notional amount. These certificates will not receive distributions of principal.

3	The Class II-A-3, Class III-A-3 and Class A-PO certificates are principal-only certificates and are not entitled to payment of interest.

4	The Class R certificates will represent the sole class of residual interests in each REMIC.

The pass-through rate of the Class I-IO, Class II-IO and Class III-IO Certificates varies according to the weighted average of the excess of the Net Mortgage Rate on the Premium Mortgage Loans in the related loan group over the related pool strip rate, (which is 6.00%, 6.50% and 6.00% for loan group I, loan group II and loan group III, respectively). For the purpose of calculating interest payments on the Class I-IO, Class II-IO and Class III-IO Certificates, interest will accrue on a notional amount equal to the aggregate Stated Principal Balance of the Premium Mortgage Loans in the related loan group, which is initially $132,866,955, $65,796,623 and $35,828,661 for loan group I, loan group II and loan group III, respectively.

The pass-through rate on the Class B-1, Class B-2, Class B-3, Class B-4, Class B-5 and Class B-6 Certificates will be equal to a per annum rate equal to the weighted average of the Group I Strip Rate, Group II Strip Rate and Group III Strip Rate weighted on the basis of the Subordinate Amount for the related loan group. The initial pass-through rate for the Class B-1, Class B-2, Class B-3, Class B-4, Class B-5 and Class B-6 Certificates will be equal to approximately 6.12017% per annum.

Certain proportions of the Exchangeable Certificates and Exchanged Certificates may be deposited in exchange for one or more classes of Exchanged Certificates, as applicable, as described under this prospectus supplement under “Description of the Certificates—Exchangeable Certificates.” The maximum initial class certificate balances or notional amounts of the Exchangeable Certificates are set forth in the table but are not included in the aggregate class certificate balance of all the certificates offered.

8	Subject to minimum and maximum rates as described in this prospectus supplement.

9	The pass-through rate on the Class A-X Certificates will be equal to the weighted average of the pass-through rates of the Class I-IO, Class II-IO and Class III-IO Certificates, weighted in proportion to their respective Notional Amounts.

It is understood and agreed that the representations and warranties of the Sponsor set forth in Section 4 of the Purchase Agreement and assigned to the Trustee by the Depositor hereunder shall survive the transfer of the Mortgage Loans by the Depositor to the Trustee on the Closing Date, and shall inure to the benefit of the Trustee and the Certificateholders notwithstanding any restrictive or qualified endorsement on any Mortgage Note or Assignment of Mortgage and shall continue throughout the term of this Agreement. Upon the discovery by any of the Sponsor, the Depositor, the Securities Administrator, the Trustee, the Master Servicer or any Servicer of a breach of any of the Sponsor’s representations and warranties set forth in Section 4 of the Purchase Agreement, the party discovering the breach shall give prompt written notice to the others.

It is understood and agreed that the obligations of the Sponsor under this Agreement to cure, repurchase or substitute any Mortgage Loan as to which a breach of a representation and warranty has occurred and is continuing, together with any related indemnification obligations of the Sponsor set forth in Section 2.03(b), shall constitute the sole remedies against the Sponsor available to the Certificateholders, the Depositor and any of its affiliates, or the Trustee on their behalf.

The provisions of this Section 2.03 shall survive delivery of the respective Custodial Files to the Custodian for the benefit of the Certificateholders.

Section 2.04 Execution and Delivery of Certificates.

(b) To the extent provided in the related Servicing Agreement, on each Remittance Date, each Servicer shall remit in immediately available funds to the Master Servicer or Securities Administrator, as applicable, an amount equal to the aggregate amount of P&I Advances, if any, to be made in respect of the Mortgage Loans and REO Properties for the related Remittance Date either (i) from its own funds or (ii) from the Collection Account, to the extent of funds held therein for future distribution (in which case, it will cause to be made an appropriate entry in the records of the Collection Account that Amounts Held for Future Distribution have been, as permitted by this Section 3.07, used by it in discharge of any such P&I Advance) or (iii) in the form of any combination of (i) and (ii) aggregating the total amount of P&I Advances to be made by the applicable Servicer with respect to the Mortgage Loans and REO Properties.

(d) To the extent provided in the related Servicing Agreement, notwithstanding anything herein to the contrary, no P&I Advance or Servicing Advance shall be required to be made hereunder by any Servicer if such P&I Advance or Servicing Advance would, if made, constitute a Nonrecoverable P&I Advance or Nonrecoverable Servicing Advance. To the extent provided in the related Servicing Agreement, the determination by any Servicer that it has made a Nonrecoverable P&I Advance or a Nonrecoverable Servicing Advance or that any proposed P&I Advance or Servicing Advance, if made, would constitute a Nonrecoverable P&I Advance or a Nonrecoverable Servicing Advance, respectively, shall be evidenced by a Servicing Officer’s certificate of the applicable Servicer delivered to the Master Servicer. In addition, to the extent provided in the related Servicing Agreement, the Servicer shall not be required to advance any Relief Act Interest Shortfalls.

(e) To the extent provided in the related Servicing Agreement, except as otherwise provided herein, the Servicer shall be entitled to reimbursement pursuant the applicable section of its related Servicing Agreement for Servicing Advances from recoveries from the related Mortgagor or from all Liquidation Proceeds and other payments or recoveries (including Insurance Proceeds, Condemnation Proceeds and Subsequent Recoveries) with respect to the related Mortgage Loan.

(xvi) to the Senior Certificates related to any Loan Group, in the priority set forth in Section 4.02(b), the portion, if any, of the related Available Funds remaining after the foregoing distributions, applied to reduce the Class Certificate Balances of such Senior Certificates, but in no event more than the aggregate of the outstanding Class Certificate Balances of each such Class of Senior Certificates, and thereafter, to each Class of Subordinate Certificates then outstanding beginning with such Class with the Highest Priority, any portion of the related Available Funds remaining after the related Senior Certificates have been retired, applied to reduce the Class Certificate Balance of each such Class of Subordinate Certificates, but in no event more than the outstanding Class Certificate Balance of each such Class of Subordinate Certificates;

(xvii) to Component R-3 of the Class R Certificates, the balance, if any, of the Available Funds for either Loan Group.

Notwithstanding the foregoing, on any Distribution Date, with respect to the Class of Subordinate Certificates outstanding on such Distribution Date with the Lowest Priority, or in the event the Subordinate Certificates are no longer outstanding, the Senior Certificates, Accrued Certificate Interest thereon remaining unpaid from any previous Distribution Date shall be distributable only to the extent that (1) a shortfall in the amounts available to pay Accrued Certificate Interest in any Class of related certificates results from an interest rate reduction in connection with a Servicing Modification on a Mortgage Loan in the related Loan Group, or (2) such unpaid Accrued Certificate Interest was attributable to interest shortfalls relating to the failure of the related Servicer to the Master Servicer to make any required Advance, or the determination by the Servicer or the Master Servicer that any proposed Advance would be a Nonrecoverable P&I Advance with respect to the related Mortgage Loan where such Mortgage Loan has not yet been the subject of a Cash Liquidation or REO Disposition.

(b) Distributions of principal on the Senior Certificates (other than the Class PO Certificates and Interest Only Certificates) on each Distribution Date occurring prior to the Credit Support Depletion Date shall be made as follows:

(i) the Senior Principal Distribution Amount for Loan Group I will be distributed sequentially as follows:

(A) to the Class R Certificates, until the Class Certificate Balance of the Class R Certificates has been reduced to zero; and

(B) any remaining amount to the Class I-A-1 Certificates, until the Class Certificate Balance of the Class I-A-1 Certificates has been reduced to zero.

(ii) the Senior Principal Distribution Amount for Loan Group II will be distributed to the Class II-A-1 Certificates and Class II-A-3 Certificates, pro rata, based on each class’s Certificate Principal Balance, until the Class Certificate Balance of the Class II-A-1 and Class II-A-3 Certificates, respectively, has been reduced to zero.

(iii) the Senior Principal Distribution Amount for Loan Group III will be distributed to the Class III-A-1 Certificates and Class III-A-3 Certificates, pro rata, based on each class’s Certificate Principal Balance, until the Class Certificate Balance of the Class III-A-1 and Class III-A-3 Certificates, respectively, has been reduced to zero.

(c) Prior to the occurrence of the Credit Support Depletion Date but after the reduction of the Class Certificate Balances of the Senior Certificates (other than any Class PO Certificates) related to any Loan Group to zero, if either (i) the Subordinate Percentage for such Loan Group on that date is less than 200% of the Subordinate Percentage as of the Closing Date or (ii) the Stated Principal Balance of the Mortgage Loans in any Loan Group delinquent 60 days or more (including, for this purpose, Mortgage Loans in REO, foreclosure or bankruptcy status) averaged over the six months prior to the Determination Date, as a percentage of such aggregate Class Certificate Balance of the Subordinate Certificates, is greater than or equal to 50%, all Scheduled Payments, Principal Prepayments or any other payment of principal received or advanced with respect to the Mortgage Loans in the Loan Group (less the Discount Fraction of such payments with respect to any Discount Mortgage Loan in that Loan Group) relating to the Senior Certificates of which the aggregate Class Certificate Balance has been paid in full, will be applied on the related Distribution Date as a distribution of principal to the remaining Senior Certificates (other than the related Class PO Certificates and Interest Only Certificates) of such other Certificate Groups, pro rata, on the basis of the aggregate Class Certificate Balance of the Senior Certificates of such Certificate Groups rather than applied as a principal distribution to the Subordinate Certificates. Such principal will be distributed on the related Distribution Date in the same priority as those Senior Certificates would receive other distributions of principal;

(d) If on any Distribution Date prior to the Credit Support Depletion Date any Loan Group is an Undercollateralized Certificate Group and any other Loan Group is an Overcollateralized Group, in each case after giving effect to distributions to be made on such Distribution Date, all Scheduled Payments, Principal Prepayments and any other payments of principal received or advanced with respect to the Mortgage Loans allocable to the related Overcollateralized Group (less the Discount Fraction of such payments with respect to any Discount Mortgage Loan in that Loan Group) will be paid in the following priority: (1) first, such amount, up to the Total Transfer Amount for that Undercollateralized Group will be distributed first to the Senior Certificates (other than the Class PO Certificates) related to the Undercollateralized Group in payment of accrued but unpaid interest, if any, and then to those Senior Certificates (other than the Class PO Certificates and Interest Only Certificates) as principal (in accordance with the priorities set forth in Section 4.02(b)) and (2) second, any remaining amount will be distributed to the Subordinate Certificates (in accordance with the priorities set forth in Section 4.02(b); provided, that if more than one Undercollateralized Group exists on any Distribution Date, the related Transfer Payments shall be allocated among such Undercollateralized Groups, pro rata, on the basis of the amount by which the aggregate Class Certificate Balance of the related Senior Certificates (other than the Class PO Certificates) immediately prior to such Distribution Date is greater than the aggregate Stated Principal Balance of the Mortgage Loans (less the Discount Fraction of any Discount Mortgage Loans) in the related Loan Group; provided, further, that if more than one Overcollateralized Group exists on any Distribution Date the related Transfer Payments shall be allocated among such Overcollateralized Groups, pro rata, on the basis of the Class Certificate Balance of the related Senior Certificates (other than the Class PO Certificates).

(e) [Reserved].

(f) After the reduction of the Class Certificate Balances of the Senior Certificates of any Certificate Group (other than the Class PO Certificates) to zero but prior to the Credit Support Depletion Date, the Senior Certificates (other than the related Class PO 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 related Class PO, Class IO, and 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, other than any related Excess Bankruptcy Losses, Excess Fraud Losses, Excess Special Hazard Losses and Extraordinary Losses, 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 application of Subsequent Recoveries to the Senior Certificates will be made in proportion to the allocation of the original Realized Loss to the Senior Certificates of the related Loan Group. 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) The Classes of Exchangeable Certificates outstanding on any Distribution Date shall be entitled to the principal and interest distributions for such Certificates pursuant to this Section 4.02. In the event that any Class of Exchangeable Certificates comprising a Combination Group are exchanged for their related Exchanged Certificates, such Exchanged Certificates shall be entitled to the principal distributions that would be allocable to the related Exchangeable Certificates pursuant to this Section 4.02 if such Exchangeable Certificates were outstanding on such date. Such Exchanged Certificates shall also be entitled to the combined Pass-Through Rate of the related Exchangeable Certificates.

(j) 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.

(k) On each Distribution Date, the Securities Administrator shall withdraw from the Distribution Account all amounts representing Prepayment Charges in respect of the Mortgage Loans received during the related Prepayment Period and will distribute these amounts to the holders of the Class P Certificates. 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(c) to the holders of the Class P Certificates, up to its Class Certificate Balance.

(l) [Reserved].

(m) [Reserved].

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;

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

(viii) by Loan Group and in the aggregate, 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;

(xii) in the aggregate and for each Class of Certificates, the aggregate amount of Realized Losses incurred during the preceding calendar month and aggregate Realized Losses through such Distribution Date;

(xiii) the amount of any Bankruptcy Losses, Fraud Losses, Special Hazard Losses or Extraordinary Losses sustained through such Distribution Date;

(b) 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.

(c) The Securities Administrator’s responsibility for making available the above statement to the Certificateholders, each Rating Agency, the Master Servicer, each Servicer, the Trustee and the Depositor is limited to the availability, timeliness and accuracy of the information derived from the Master Servicer and the Servicers. The Securities Administrator will provide the above statement via the Securities Administrator’s internet website. The Securities Administrator’s website will initially be located at xxxxx://xxx.xx.xxxxxxxxxx.xxx and assistance in using the website can be obtained by calling the Securities Administrator’s customer service desk at (0-000) 000-0000.

The Securities Administrator shall have the right to change the manner in which the above statement is distributed in order to make such distribution more convenient and/or more accessible, and the Securities Administrator shall provide timely and adequate notification to the Certificateholders and the parties hereto regarding any such changes. A paper copy of the statement will also be made available upon written request.

(d) Within a reasonable period of time after the end of each calendar year, the Securities Administrator shall, upon written request, cause to be furnished to each Person who at any time during the calendar year was a Certificateholder, a statement containing the information set forth in clauses (a)(i), (a)(ii), and (a)(vi) of this Section 4.03 aggregated for such calendar year or applicable portion thereof during which such Person was a Certificateholder. Such obligation of the Securities Administrator shall be deemed to have been satisfied to the extent that substantially comparable information shall have previously been provided by the Securities Administrator pursuant to any requirements of the Code as from time to time in effect.

(e) 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 Master Servicer shall determine the total amount of Realized Losses, based solely upon the information provided by the Servicers (to the extent provided by them), if any, that resulted from any Cash Liquidation, Servicing Modification, Debt Service Reduction, 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 Officers’ Certificate provided by the Servicers. With respect to all Realized Losses (i) the principal portion of Realized Losses, other than Excess Special Hazard Losses, Extraordinary Losses, Excess Bankruptcy Losses or Excess Fraud 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, if any such Realized Losses are on a Discount Mortgage Loan, to the related Class PO Certificates in an amount equal to the Discount Fraction of the principal portion of such Discount Mortgage Loan, and the remainder of such Realized Losses on that Discount Mortgage Loan will be allocated among all remaining classes of Senior Certificates (other than the Interest Only Certificates and Class PO Certificates) related to the Loan Group that includes that Discount Mortgage Loan and the amount of any Realized Loss on any Non-Discount Mortgage Loans included in any Loan Group will be allocated among all the remaining classes of Senior Certificates (other than the Interest Only Certificates and Class PO 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, other than any Excess Special Hazard Losses, Extraordinary Losses, Excess Bankruptcy Losses or Excess Fraud 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 (other than the Class PO 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 II-A-12 Certificates will be allocated to the Class II-A-13 Certificates until the Class Certificate Balance of the Class II-A-13 Certificates has been reduced to zero and (B) such Realized Losses otherwise allocable to the Class III-A-6 Certificates will be allocated to the Class III-A-7 Certificates until the Class Certificate Balance of the Class III-A-7 Certificates has been reduced to zero.

The principal portion of any Excess Special Hazard Losses, Excess Bankruptcy Losses, Excess Fraud Losses and Extraordinary Losses on any Discount Mortgage Loan shall be allocated to the related Class PO Certificates in an amount equal to the Discount Fraction thereof and the applicable Loan Group Senior Percentage of the remainder of such Realized Loss on such Discount Mortgage Loan and the applicable Loan Group Senior Percentage of the entire amount of such Realized Loss on any Non-Discount Mortgage Loan, will be allocated among the Senior Certificates (other than the Class PO Certificates and Interest Only Certificates) related to each Loan Group that includes all or portion of such Mortgage Loan. The remainder of the principal portion of such losses will be allocated to the Subordinate Certificates. The interest portion of such losses will be allocated to all of the Certificates related to the Loan Group that includes such Mortgage Loan, on a pro rata basis, based on the Accrued Certificate Interest thereon payable from the related Loan Group in respect to the related Distribution Date, provided, however, that (A) such Realized Losses otherwise allocable to the Class II-A-12 Certificates will be allocated to the Class II-A-13 Certificates until the Class Certificate Balance of the Class II-A-13 Certificates has been reduced to zero and (B) such Realized Losses otherwise allocable to the Class III-A-6 Certificates will be allocated to the Class III-A-7 Certificates until the Class Certificate Balance of the Class IIII-A-7 Certificates has been reduced to zero.

In addition, the Classes of Exchangeable Certificates outstanding on any Distribution Date shall bear the share of Realized Losses and interest shortfalls allocable to such Class of Certificates as provided in this Section 4.04 and the definition of Accrued Certificate Interest. In addition, such Exchanged Certificates shall be allocated the Realized Losses and interest shortfalls that would be allocable to each of the Classes of related Exchangeable Certificates in a Combination Group pursuant to this Section 4.04 and the definition of Accrued Certificate Interest were such Classes of Exchangeable Certificates outstanding on such date. Such Realized Losses and interest shortfalls shall be allocated among the Exchanged Certificates as provided in this Section 4.04 and the definition of Accrued Certificate Interest.

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.

Section 4.05 [Reserved].

Section 4.06 Certain Matters Relating to the Determination of LIBOR. LIBOR shall be calculated by the Securities Administrator in accordance with the definition of LIBOR. The Interest Rate for each Class of Adjustable Rate Certificates for each Interest Accrual Period shall be determined by the Securities Administrator on each Adjustable Rate Determination Date so long as the Adjustable Rate Certificates are outstanding on the basis of LIBOR and the respective Pass-Through Rate relating to the Certificates. The establishment of LIBOR by the Securities Administrator and the Securities Administrator’s subsequent calculation of the Pass-Through Rate applicable to the Adjustable Rate Certificates for the relevant Interest Accrual Period, in the absence of manifest error, will be final and binding.

ARTICLE V

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.

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.

(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 144 A 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.

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.

(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

(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.

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.

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. The Securities Administrator initially designates its offices located at 000 Xxxx Xxxxxx, 00^xx Xxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000, Attention: Corporate Trust Services HALO 2007-1. The Securities Administrator shall give prompt written notice to the Certificateholders of any change in such location of any such office or agency.

Section 5.07 Exchangeable Certificates.

(a) Upon the presentation and surrender by any Certificateholder of its Exchangeable Certificates or Exchanged Certificates, as applicable, in the appropriate combination as set forth on Schedule II, such Certificateholder shall hereunder transfer, assign, set over and otherwise convey to the Securities Administrator, all of such Certificateholder’s right, title and interest in and to such Exchangeable Certificates or Exchanged Certificates, as applicable.

The Exchangeable and Exchanged Certificates shall be transferred in uncertificated form to the Underwriter pursuant to Section 3 of the Underwriting Agreement. The Exchangeable or Exchanged Certificates in which the Underwriter does not take an initial position in on the books of DTC shall be transferred by the Underwriter to the Securities Administrator to be held in trust. Citibank, N.A., acting in its capacity as Securities Administrator, acknowledges (i) the transfer and assignment to it of the uncertificated Exchangeable or Exchanged Certificates, as applicable, pursuant to this Section 5.07 and Section 3 of the Underwriting Agreement and (ii) any transfer and assignment of uncertificated Exchangeable or Exchanged Certificates, as applicable, pursuant to the foregoing paragraph, and hereby declares that it will hold the same in trust for the Certificateholders on the terms contained in this Agreement.

Upon any such exchange, the portions of the Exchangeable Certificates designated for exchange shall be deemed exchanged and replaced by the Exchanged Certificates issued in exchange therefore. Correspondingly, Exchanged Certificates related to a Combination Group may be further designated for exchange for the Exchangeable Certificates (or for other Exchanged Certificates, if applicable) related to a Combination Group in respective denominations determined based on the proportion that the initial Certificate Principal Balances of such Exchanged Certificates bear to the original Certificate Principal Balances of the Exchangeable Certificates or the related Exchanged Certificates, in each case, as set forth in Schedule II. There shall be no limitation on the number of exchanges authorized pursuant to this Section 5.07, and, except as provided below, no fee or other charge shall be payable to the Securities Administrator or DTC in connection therewith.

In order to effect an exchange of Certificates, the Certificateholder shall notify the Securities Administrator in writing, substantially in the form of Exhibit Z, and in accordance with the requirements set forth herein, no earlier than the first calendar day of each month and no later than three Business Days before the proposed exchange date. The exchange date will be subject to the Securities Administrator’s approval but it can generally be any Business Day other than the first and last Business Days of the month and subject to the preceding sentence.

The Securities Administrator shall make the first distribution on an Exchangeable Certificate or an Exchanged Certificate received in an exchange transaction on the Distribution Date in the following month to the Certificateholder of record as of the close of business on the last day of the month of the exchange.

Section 5.08 Tax Status and Reporting of Exchangeable Certificates.

(a) It is intended that the Grantor Trust be classified for federal income tax purposes as a grantor trust under Subpart E, part I of subchapter J of chapter 1 of the Code, and the powers granted and obligations undertaken in this Agreement shall be construed so as to further such intent. Under no circumstances shall the Securities Administrator, the Trustee, the Master Servicer or the Depositor have the power to vary the investments of the Holders of Exchangeable Certificates or Exchanged Certificates in their related assets of the Grantor Trust in order to take advantage of variations in the market to improve their rate of return. The Exchangeable Certificates and the Exchanged Certificates represent undivided beneficial ownership of the Grantor Trust Uncertificated REMIC 3 Regular Interests identified as related to such Certificates in the definition of Uncertificated REMIC 3 Regular Interests.

(b) The Securities Administrator shall prepare or cause to be prepared all of the Tax Returns that it determines are required with respect to the Grantor Trust and deliver such Tax Returns in a timely manner to the Trustee, and, if required by applicable law, the Trustee is directed to and shall sign and file such Tax Returns in a timely manner. The expenses of preparing such returns shall be borne by the Securities Administrator without any right of reimbursement therefor. The Master Servicer shall promptly provide the Securities Administrator with such information as the Securities Administrator may from time to time request for the purpose of enabling the Securities Administrator to prepare such Tax Returns.

(c) Each beneficial owner of an Exchangeable Certificate or an Exchanged Certificate shall be deemed to have instructed the Securities Administrator to deposit the related Grantor Trust Uncertificated REMIC 3 Regular Interests into the Grantor Trust. The Securities Administrator shall establish and maintain a Grantor Trust Account. On each Distribution Date, the Master Servicer on behalf of the Securities Administrator (or the Paying Agent appointed by the Securities Administrator) shall deposit into the Grantor Trust Account all amounts deemed distributed with respect to Grantor Trust Uncertificated REMIC 2 Regular Interests pursuant to the provisions of Section 11.04(b).

(d) The Grantor Trust is a WHFIT that is a WHMT. The Securities Administrator will report as required under the WHFIT Regulations to the extent such information is reasonably necessary. The Securities Administrator is hereby directed pursuant to this Agreement to assume that DTC is the only "middleman" (as such term is defined in the WHFIT Regulations) unless the Depositor, the Master Servicer or the Trustee notifies the Securities Administrator in writing of the identities of other "middlemen" that are Holders of Exchangeable Certificates or Exchanged Certificates.

(e) The Securities Administrator will report required WHFIT information using the accrual method, except to the extent the WHFIT Regulations specifically require a different method. The Securities Administrator will be under no obligation to determine whether any Exchangeable or Exchanged Certificateholder or other beneficial owner of an Exchangeable Certificate or an Exchanged Certificate, to the extent the Securities Administrator knows of any other beneficial owner of an Exchangeable Certificate or an Exchanged Certificate, uses the cash or accrual method. The Securities Administrator will make available information as required by the WHFIT Regulations to Exchangeable and Exchanged Certificateholders annually. In addition, the Securities Administrator will not be responsible or liable for providing subsequently amended, revised or updated information to any Exchangeable or Exchanged Certificateholder, unless requested in writing by such Certificateholder.

(f) To the extent required by the WHFIT Regulations, the Securities Administrator will use reasonable efforts to publish on an appropriate website the CUSIP Numbers for the Exchangeable Certificates and the Exchanged Certificates. The Securities Administrator will make reasonable good faith efforts to keep the website accurate and updated to the extent CUSIP Numbers have been received. The Securities Administrator will not be liable for investor reporting delays that result from the receipt of inaccurate or untimely CUSIP Number information.

DEFAULT

Section 7.01 Master Servicer to Act; Appointment of Successor. (a) The Master Servicer or the Trustee (as successor master servicer), as applicable, shall be entitled to terminate the rights and obligations of any Servicer under the applicable Servicing Agreement in accordance with the terms and conditions of such Servicing Agreement and without any limitation by virtue of this Agreement. Upon termination of a Servicer under the applicable Servicing Agreement, the Master Servicer or the Trustee (as successor master servicer), as applicable, shall, subject to the rights of the Master Servicer or the Trustee (as successor master servicer), as applicable, to appoint a successor servicer pursuant to this Section 7.01, be the successor to such Servicer in its capacity as servicer under the applicable Servicing Agreement, provided, however, that the Master Servicer or the Trustee (as successor master servicer), as applicable, shall not be (i) liable for losses of the predecessor Servicer with respect to such predecessor’s investment of funds in its Collection Account; (ii) obligated to effectuate repurchases or substitutions of Mortgage Loans hereunder, including but not limited to repurchases or substitutions pursuant to Section 2.03, (iii) responsible for expenses of the predecessor servicer related to any repurchase or substitution of Mortgage Loans hereunder, including but not limited to repurchases or substitutions pursuant to Section 2.03, (iv) deemed to have made any of the representations and warranties of the terminated Servicer under the applicable Servicing Agreement or (v) liable for any obligations of the predecessor Servicer incurred prior to its termination.

(b) It is understood and acknowledged by the parties hereto that there will be a period of transition before the transfer of servicing obligations is fully effective. Notwithstanding the foregoing, the Master Servicer or the Trustee (as successor master servicer), as applicable, will have a period (not to exceed 90 days) to complete the transfer of all servicing data and correct or manipulate such servicing data as may be required by the Master Servicer or the Trustee (as successor master servicer), as applicable, to correct any errors or insufficiencies in the servicing data or otherwise enable the Master Servicer or the Trustee (as successor master servicer), as applicable, to service the Mortgage Loans in accordance with the applicable Servicing Agreement. Except as provided in Section 7.01(e) below, the Master Servicer or the Trustee (as successor master servicer), as applicable, shall be entitled to be reimbursed from each Servicer (or by the Trust Fund, if such Servicer is unable to fulfill such obligation) for all costs associated with the transfer of servicing from the predecessor servicer, including without limitation, any costs or expenses associated with the complete transfer of all servicing data and the completion, correction or manipulation of such servicing data, as may be required by the Master Servicer or the Trustee (as successor master servicer), as applicable, to correct any errors or insufficiencies in the servicing data or otherwise to enable the Master Servicer or the Trustee (as successor master servicer), as applicable, to service the Mortgage Loans properly and effectively. As compensation in its role as successor servicer, the Master Servicer or the Trustee (as successor master servicer), as applicable, shall be entitled to the applicable Servicing Fee and any income on investments or gain related to the related Collection Account. 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.

(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.

(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

(b) the Trustee shall not be liable for an error of judgment made in good faith by a Responsible Officer or Responsible Officers of the Trustee, unless it is finally proven that the Trustee was negligent in ascertaining the pertinent facts; and

(c) the Trustee shall not be liable with respect to any action taken, suffered, or omitted to be taken by it in good faith in accordance with the direction of the Holders of Certificates evidencing not less than 25.00% of the Voting Rights of Certificates relating to the time, method, and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee under this Agreement.

(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.

Accordingly, each of the parties agrees to provide to the Trustee upon its request from time to time such identifying information and documentation as may be available to such party in order to enable the Trustee to comply with Applicable Law.

Section 8.03 Trustee Not Liable for Certificates or Mortgage Loans. The recitals contained herein and in the Certificates shall be taken as the statements of the Depositor and the Trustee assumes no responsibility for their correctness.

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 Sponsor from the Sponsor’s own funds pursuant to a separate agreement. The Trustee shall have no lien on the Trust Fund for the payment of such fees.

(b) The Trustee shall be entitled to be reimbursed, from funds on deposit in the Distribution Account, amounts sufficient to indemnify and hold harmless the Trustee and any director, officer, employee, or agent of the Trustee against any loss, liability, or expense (including reasonable attorneys’ fees and expenses) incurred in connection with any claim or legal action relating to:

(ii) the Certificates, or

(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:

(A) the reasonable compensation, expenses, and disbursements of its counsel not associated with the closing of the issuance of the Certificates, and

Except as otherwise provided in this Agreement or a separate letter agreement between the Trustee and the Depositor, the Trustee shall not be entitled to payment or reimbursement for any routine ongoing expenses incurred by the Trustee in the ordinary course of its duties as Trustee under this Agreement or for any other routine expenses incurred by the Trustee; provided, further, that no expense shall be reimbursed hereunder if it would not constitute an “unanticipated expense incurred by the REMIC” within the meaning of the REMIC Provisions.

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.

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 Holders of Certificates entitled to at least a majority of the Voting Rights may at any time remove the Trustee and, subject to the approval of the Rating Agencies, appoint a successor trustee by written instrument or instruments, in triplicate, signed by such Holders or their attorneys-in-fact duly authorized, one complete set of which shall be delivered by the successor Trustee to each Servicer, one complete set to the Trustee so removed and one complete set to the successor so appointed. 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.

Section 8.08 Successor Trustee. 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.

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;

(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 (for execution by the Master Servicer) and file with the Commission, via XXXXX, 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 XXXXX-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.

(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. 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.

(D) Form 10-D requires the registrant to indicate (by checking “yes” or “no”) that it “(1) has filed all reports required to be filed by Section 13 or 15(d) of the Exchange Act during the preceding 12 months (or for such shorter period that the registrant was required to file such reports), and (2) has been subject to such filing requirements for the past 90 days.” The Depositor hereby instructs the Administrator to check “Yes” for each item, unless the Depositor shall notify the Securities Administrator in writing, no later than the fifth calendar day after the related Distribution Date with respect to the filing of a report on Form 10-D, that the answer to either item should be “no.” The Depositor has filed all reports required to be filed by Section 13 or 15(d) of the Exchange Act during the preceding 12 months (or for such shorter period that the Depositor was required to file such reports) and it has been subject to such filing requirement for the past 90 days.” The Securities Administrator shall be entitled to rely on such representations in preparing, executing and/or filing any such Form 10-D.

(ii) (A) On or prior to the 90^th day after the end of each fiscal year of the Trust or such earlier date as may be required by the Exchange Act (the “10-K Filing Deadline”) (it being understood that the fiscal year for the Trust ends on December 31^st of each year), for so long as the Depositor is required to file reports with respect to the Trust under the Exchange Act, commencing in March 2008, the Securities Administrator shall prepare (for execution by the Master Servicer) and file on behalf of the Trust a Form 10-K, in form and substance as required by the Exchange Act. Each such Form 10-K shall include the following items, in each case to the extent they have been delivered to the Securities Administrator within the applicable time frames set forth in this Agreement or the Servicing Agreements, (i) an annual compliance statement for each Servicer and the Master Servicer and any Servicing Function Participant engaged by any such party (together with the Custodian and the Securities Administrator, each a “Reporting Servicer”) as described under Section 3.05(b), (ii)(A) the annual reports on assessment of compliance with Servicing Criteria for each Reporting Servicer, as described under Section 3.03, and (B) if any Reporting Servicer’s report on assessment of compliance with Servicing Criteria described under Section 3.03 identifies any material instance of noncompliance, disclosure identifying such instance of noncompliance, or if any Reporting Servicer’s report on assessment of compliance with Servicing Criteria described under Section 3.03 is not included as an exhibit to such Form 10-K, disclosure that such report is not included and an explanation why such report is not included, provided, however, that the Securities Administrator, at its discretion, may omit from the Form 10-K any assessment of compliance or attestation report described in clause (iii) below that is not required to be filed with such Form 10-K pursuant to Regulation AB; (iii)(A) the registered public accounting firm attestation report for each Reporting Servicer, as described under Section 3.04, and (B) if any registered public accounting firm attestation report described under Section 3.04 identifies any material instance of noncompliance, disclosure identifying such instance of noncompliance, or if any such registered public accounting firm attestation report is not included as an exhibit to such Form 10-K, disclosure that such report is not included and an explanation why such report is not included, and (iv) a Xxxxxxxx-Xxxxx Certification as described in Section 3.05. Any disclosure or information in addition to (i) through (iv) above that is required to be included on Form 10-K (“Additional Form 10-K Disclosure”) shall be reported by the parties set forth on Exhibit W 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 any failure hereunder to determine or prepare any Additional Form 10-K Disclosure, except to the extent of its obligations set forth in the next paragraph.

(B) As set forth on Exhibit W hereto, no later than March 10 (with a 5 calendar day cure period, but in no event later than March 15) of each year that the Trust is subject to the Exchange Act reporting requirements, commencing in 2008, (i) the parties specified on Exhibit W shall be required to provide to the Securities Administrator and to the Depositor, to the extent known, in XXXXX-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-K 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-K Disclosure on Form 10-K. The Securities Administrator has no duty under this Agreement to monitor or enforce the performance by the parties listed on Exhibit W of their duties under this paragraph or proactively solicit or procure from such parties any Additional Form 10-K Disclosure information. The Depositor will be responsible for any reasonable fees and expenses assessed or incurred by the Securities Administrator in connection with including any Additional Form 10-K Disclosure on Form 10-K pursuant to this Section 8.12(a)(ii)(B).

(C) After preparing the Form 10-K, the Securities Administrator shall, upon request, forward electronically a copy of the Form 10-K to the Depositor. Within three Business Days after receipt of such copy, but no later than March 25th, the Depositor shall notify the Securities Administrator in writing (which may be furnished electronically) of any changes to or approval of such Form 10-K. In the absence of receipt of any written changes or approval, or if the Depositor does not request a copy of a Form 10-K, the Securities Administrator shall be entitled to assume that such Form 10-K is in final form and the Securities Administrator may proceed with the process for execution and filing of the Form 10-K. A senior officer of the Master Servicer in charge of the master servicing function shall sign the Form 10-K. If a Form 10-K cannot be filed on time or if a previously filed Form 10-K needs to be amended, the 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 a final executed copy of each Form 10-K prepared and filed by the Securities Administrator. The parties to this Agreement acknowledge that the performance by the Securities Administrator of its duties under this Section 8.12(a)(ii) related to the timely preparation, execution and filing of Form 10-K is contingent upon such parties strictly observing all applicable deadlines in the performance of their duties under this Section 8.12(a)(ii) and Sections 3.03, 3.04 and 3.05. The Depositor acknowledges that the performance by the Master Servicer and the Securities Administrator of its duties under this Section 8.12(ii) related to the timely preparation, execution and filing of Form 10-K 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-K Disclosure, any annual statement of compliance and any assessment of compliance and attestation 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-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 10-K, not resulting from its own negligence, bad faith or willful misconduct.

100

(D) Form 10-K requires the registrant to indicate (by checking “yes” or “no”) that it “(1) has filed all reports required to be filed by Section 13 or 15(d) of the Exchange Act during the preceding 12 months (or for such shorter period that the registrant was required to file such reports), and (2) has been subject to such filing requirement for the past 90 days.” The Depositor hereby instructs the Securities Administrator to check “Yes” for each item, unless the Depositor shall notify the Securities Administrator in writing, no later than the 15^th calendar day of March in any year in which the Trust is subject to the reporting requirements of the Exchange Act, that the answer to either item should be “no.” The Depositor has filed all reports required to be filed by Section 13 or 15(d) of the Exchange Act during the preceding 12 months (or for such shorter period that the Depositor was required to file such reports) and it has been subject to such filing requirement for the past 90 days.” The Securities Administrator shall be entitled to rely on such representations in preparing, executing and/or filing any such Form 10-K.

(iii) (A) Within four (4) Business Days after the occurrence of an event requiring disclosure on Form 8-K (each such event, a “Reportable Event”), if directed by the Depositor, the Securities Administrator shall prepare and file on behalf of the Trust Fund any Form 8-K, as required by the Exchange Act, provided that the Depositor shall file the initial Form 8-K in connection with the issuance of the Certificates. Any disclosure or information related to a Reportable Event or that is otherwise required to be included on Form 8-K (“Form 8-K Disclosure Information”) shall be reported by the parties set forth on Exhibit X 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 any failure hereunder to determine or prepare any Form 8-K Disclosure Information or any Form 8-K, except to the extent of its obligations set forth in the next paragraph.

(B) As set forth on Exhibit X hereto, for so long as the Trust is subject to the Exchange Act reporting requirements, no later than the close of business New York City time on the 2nd Business Day after the occurrence of a Reportable Event (i) the parties hereto shall be required to provide to the Securities Administrator and the Depositor, to the extent known, in XXXXX-compatible format, or in such other format as agreed upon by the Securities Administrator and such party, the form and substance of any Form 8-K Disclosure Information, 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 Form 8-K Disclosure Information. The Depositor will be responsible for any reasonable fees and expenses assessed or incurred by the Securities Administrator in connection with including any Form 8-K Disclosure Information on Form 8-K pursuant to this paragraph.

101

(C) After preparing the Form 8-K, the Securities Administrator shall, upon request, forward electronically a copy of the Form 8-K to the Depositor. 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. A duly authorized representative of the Master Servicer shall sign each Form 8-K. If a Form 8-K cannot be filed on time or if a previously filed Form 8-K needs to be amended, the Securities Administrator will follow the procedures set forth in paragraph (d) of this Section 8.12. The parties to this Agreement acknowledge that the performance by the Securities Administrator of its duties under this Section 8.12(d)(iii) related to the timely preparation, execution and filing of Form 8-K is contingent upon such parties strictly observing all applicable deadlines in the performance of their duties under this Section 8.12(D)(iii). The Depositor acknowledges that the performance by the Master Servicer and the Securities Administrator of its duties under this Section 8.12(D)(iii) related to the timely preparation, execution and filing of Form 8-K 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 Form 8-K Disclosure Information pursuant to the related any applicable agreement. 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.

(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. The Securities Administrator shall make available to the Depositor copies of all Exchange Act reports filed hereunder.

102

(d) (i) On or before January 30 of the first year in which the Securities Administrator is able to do so under applicable law, the Securities Administrator shall prepare and file a Form 15 relating to the automatic suspension of reporting in respect of the Trust under the Exchange Act.

(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 10-D and 10-K, the parties to this Agreement will cooperate to prepare and file a Form 12b-25 and a 10-DA and 10-KA as applicable, pursuant to Rule 12b-25 of the Exchange Act. 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. 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 any such Form 15, Form 12b-25 or any amendments to Forms 8-K, 10-D or 10-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 15, Form 12b-25 or any amendments to Forms 8-K, 10-D or 10-K, not resulting from its own negligence, bad faith or willful misconduct. 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.

103

(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.

(g) Any notice required under this Section 8.12 may be given by facsimile or by electronic mail.

ARTICLE IX

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 their respective Servicing Agreements, 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.

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.

104

(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.

(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. Not later than four Business Days preceding each Distribution Date, the Master Servicer shall deliver to Securities Administrator, in a format mutually agreed upon by the Master Servicer and 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 Master Servicer, at its expense, shall maintain in effect a blanket fidelity bond and an errors and omissions insurance policy, affording coverage with respect to all directors, officers, directors, employees and other Persons acting on such Master Servicer’s behalf, and covering errors and omissions in the performance of the Master Servicer’s obligations hereunder. 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.

105

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:

(i) it is a New York corporation, duly organized existing and in good standing under the laws of the State of New York, with corporate power and authority to conduct its business as presently conducted by it, and to enter into, execute and deliver and to perform its obligations as Master Servicer under this Agreement;

(ii) the execution and delivery of this Agreement by the Master Servicer and its performance and compliance with the terms of this Agreement will not (A) violate the Master Servicer’s charter or bylaws, (B) violate any law or regulation or any administrative decree or order to which it is subject or (C) constitute a default (or an event which, with notice or lapse of time, or both, would constitute a default) under, or result in the breach of, any material contract, agreement or other instrument to which the Master Servicer is a party or by which it is bound or to which any of its assets are subject, which violation, default or breach would materially and adversely affect the Master Servicer’s ability to perform its obligations under this Agreement;

(iii) this Agreement constitutes, assuming due authorization, execution and delivery hereof by the other respective parties hereto, a legal, valid and binding obligation of the Master Servicer, enforceable against it in accordance with the terms hereof, except as such enforcement may be limited by bankruptcy, insolvency, reorganization, moratorium and other laws affecting the enforcement of creditors’ rights in general, and by general equity principles (regardless of whether such enforcement is considered in a proceeding in equity or at law);

(iv) the Master Servicer is not in default with respect to any order or decree of any court or any order or regulation of any federal, state, municipal or governmental agency to the extent that any such default would materially and adversely affect its performance hereunder;

(v) the Master Servicer is not a party to or bound by any agreement or instrument or subject to any charter provision, bylaw or any other corporate restriction or any judgment, order, writ, injunction, decree, law or regulation that may materially and adversely affect its ability as Master Servicer to perform its obligations under this Agreement or that requires the consent of any third person to the execution of this Agreement or the performance by the Master Servicer of its obligations under this Agreement;

106

(vi) no litigation is pending or, to the best of the Master Servicer’s knowledge, threatened against the Master Servicer which would prohibit its entering into this Agreement or performing its obligations under this Agreement;

(vii) no consent, approval, authorization or order of any court or governmental agency or body is required for the execution, delivery and performance by the Master Servicer of or compliance by the Master Servicer with this Agreement or the consummation of the transactions contemplated by this Agreement, except for such consents, approvals, authorizations and orders (if any) as have been obtained; and

(viii) the consummation of the transactions contemplated by this Agreement are in the ordinary course of business of the Master Servicer.

(b) It is understood and agreed that the representations and warranties set forth in this Section shall survive the execution and delivery of this Agreement. The Master Servicer shall indemnify the Depositor, the Securities Administrator, the Trustee and the Trust and hold them harmless against any loss, damages, penalties, fines, forfeitures, reasonable legal fees and related costs, judgments, and other reasonable costs and expenses resulting from any claim, demand, defense or assertion based on or grounded upon, or resulting from, a material breach of the Master Servicer’s representations and warranties contained in Section 9.05(a) above. 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, the Trustee and the Trust constitutes the sole remedy of the Depositor and the Trustee, respecting a breach of the foregoing representations and warranties. Such indemnification shall survive any termination of the Master Servicer as Master Servicer hereunder, any termination of this Agreement and resignation or removal of the Trustee.

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 9.06 Master Servicer Events of Default. Each of the following shall constitute a “Master Servicer Event of Default”:

(a) any failure by the Master Servicer to cause to be deposited in the Distribution Account any amounts received by it from the Servicers or to make any P&I Advance required to be made by the Master Servicer under the terms of this Agreement which continues unremedied for a period of two (2) Business Days after the date upon which written notice of such failure, requiring the same to be remedied, shall have been given to the Master Servicer by any other party hereto;

(b) failure by the Master Servicer to duly observe or perform, in any material respect, any other covenants, obligations or agreements of the Master Servicer as set forth in this Agreement which failure continues unremedied for a period of thirty (30) days after the date on which written notice of such failure, requiring the same to be remedied, shall have been given to the Master Servicer by the Trustee or to the Master Servicer and Trustee by the holders of Certificates evidencing at least 25.00% of the Voting Rights;

107

(c) a decree or order of a court or agency or supervisory authority having jurisdiction for the appointment of a conservator or receiver or liquidator in any insolvency, bankruptcy, readjustment of debt, marshaling of assets and liabilities or similar proceedings, or for the winding-up or liquidation of its affairs, shall have been entered against the Master Servicer and such decree or order shall have remained in force, undischarged or unstayed for a period of sixty (60) days;

(d) the Master Servicer shall consent to the appointment of a conservator or receiver or liquidator in any insolvency, bankruptcy, readjustment of debt, marshaling of assets and liabilities or similar proceedings of or relating to the Master Servicer or relating to all or substantially all of its property;

(e) the Master Servicer shall admit in writing its inability to pay its debts as they become due, file a petition to take advantage of any applicable insolvency or reorganization statute, make an assignment for the benefit of its creditors, or voluntarily suspend payment of its obligations for three (3) Business Days;

(f) Except as otherwise set forth herein, the Master Servicer attempts to assign this Agreement or its responsibilities hereunder or to delegate its duties hereunder (or any portion thereof) without the consent of the Securities Administrator and the Depositor;

(g) the indictment of the Master Servicer for the taking of any action by the Master Servicer, any Affiliate or any director or employee thereof that constitutes fraud or criminal activity in the performance of its obligations under this Agreement, in each case, where such indictment materially and adversely affects the ability of the Master Servicer to perform its obligations under this Agreement (subject to the condition that such indictment is not dismissed within ninety (90) days);

(h) After receipt of notice from the Securities Administrator, any failure of the Master Servicer to remit to the Securities Administrator any payment required to be made to the Securities Administrator for the benefit of Certificateholders under the terms of this Agreement, including any Advance, on any Master Servicer Remittance Date which such failure continues unremedied for a period of one Business Day after the date upon which notice of such failure shall have been given to the Master Servicer by the Securities Administrator; or

(i) failure of the Master Servicer to timely provide the Depositor with the assessment, attestation and annual statement of compliance required by Item 1122 of Regulation AB in accordance with Sections 3.03, 3.04 and 3.05.

In each and every such case, so long as a Master Servicer Event of Default shall not have been remedied, in addition to whatever rights the Trustee may have at law or equity or to damages, including injunctive relief and specific performance, the Trustee, by notice in writing to the Master Servicer, may, and upon the request of the Holders of Certificates representing at least 51.00% of the Voting Rights shall, terminate with cause all the rights and obligations of the Master Servicer under this Agreement.

108

Upon receipt by the Master Servicer of such written notice, all authority and power of the Master Servicer under this Agreement, shall pass to and be vested in any successor master servicer appointed hereunder which accepts such appointments. Upon written request from the Trustee or the Depositor, the Master Servicer shall prepare, execute and deliver to the successor entity designated by the Trustee any and all documents and other instruments related to the performance of its duties hereunder as the Master Servicer and, place in such successor’s possession all such documents with respect to the master servicing of the Mortgage Loans and do or cause to be done all other acts or things necessary or appropriate to effect the purposes of such notice of termination, at the Master Servicer’s sole expense. The Master Servicer shall cooperate with the Trustee and such successor master servicer in effecting the termination of the Master Servicer’s responsibilities and rights hereunder, including without limitation, the transfer to such successor master servicer for administration by it of all cash amounts which shall at the time be credited to the Master Servicing Account or are thereafter received with respect to the Mortgage Loans.

Section 9.07 Waiver of Default. By a written notice, the Trustee may at the direction of Holders of Certificates evidencing at least 51.00% of the Voting Rights waive any default by the Master Servicer in the performance of its obligations hereunder and its consequences. Upon any waiver of a past default, such default shall cease to exist, and any Master Servicer Event of Default arising therefrom shall be deemed to have been remedied for every purpose of this Agreement. No such waiver shall extend to any subsequent or other default or impair any right consequent thereon except to the extent expressly so waived.

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 Xxxxxx Xxx and Xxxxxxx 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).

109

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.

Section 9.09 [Reserved].

Section 9.10 Merger or Consolidation. Any Person into which the Master Servicer may be merged or consolidated, or any Person resulting from any merger, conversion, other change in form or consolidation to which the Master Servicer shall be a party, or any Person succeeding to the business of the Master Servicer, shall be the successor to the Master Servicer hereunder, without the execution or filing of any paper or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding; provided, however, that the successor or resulting Person to the Master Servicer shall (i) be a Person (or have an Affiliate) that is qualified and approved to service mortgage loans for Xxxxxx Xxx and Xxxxxxx Mac (provided further that a successor master servicer that satisfies subclause (i) through an Affiliate agrees to service the Mortgage Loans in accordance with all applicable Xxxxxx Mae and Xxxxxxx Mac guidelines) and (ii) have a net worth of not less than $25,000,000.

110

Section 9.11 Resignation of the Master Servicer. Except as otherwise provided in Sections 9.08 and 9.10 hereof, the Master Servicer shall not resign from the obligations and duties hereby imposed on it unless the Master Servicer’s duties hereunder are no longer permissible under applicable law or are in material conflict by reason of applicable law with any other activities carried on by it and cannot be cured. Any such determination permitting the resignation of the Master Servicer shall be evidenced by an Opinion of Counsel that shall be independent to such effect delivered to the Trustee. No such resignation shall become effective until the Trustee shall have assumed, or a successor master servicer satisfactory to the Trustee and the Depositor shall have assumed, the Master Servicer’s responsibilities and obligations under this Agreement. Notice of such resignation shall be given promptly by the Master Servicer and the Depositor to the Trustee.

If at any time, CitiMortgage, as Master Servicer, resigns under this Section 9.11, or is removed as Master Servicer pursuant to Section 9.06, then at such time Citibank shall also resign (and shall be entitled to resign) as Securities Administrator under this Agreement.

Section 9.12 Assignment or Delegation of Duties by the Master Servicer. Except as expressly provided herein, the Master Servicer shall not assign or transfer any of its rights, benefits or privileges hereunder to any other Person, or delegate to or subcontract with, or authorize or appoint any other Person to perform any of the duties, covenants or obligations to be performed by the Master Servicer; provided, however, that the Master Servicer shall have the right with the prior written consent of the Depositor (which shall not be unreasonably withheld, denied, or delayed), and upon delivery to the Trustee and the Depositor of a letter from each Rating Agency to the effect that such action shall not result in a downgrade of the ratings assigned to any of the Certificates, to delegate or assign to or subcontract with or authorize or appoint any qualified Person to perform and carry out any duties, covenants or obligations to be performed and carried out by the Master Servicer hereunder. Notice of such permitted assignment shall be given promptly by the Master Servicer to the Depositor and the Trustee.

(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 12.02 Final Distribution on the Certificates. If on any Remittance Date, the Master Servicer determines that there are no Outstanding Mortgage Loans and no other funds or assets in the Trust Fund other than the funds in any Collection Account, the Master Servicer shall direct the Securities Administrator promptly to send a Notice of Final Distribution to each Certificateholder. If the Master Servicer (upon instruction from the Depositor or voluntarily) elects to exercise their option to purchase the Mortgage Loans pursuant to clause (a) of Section 12.01, at least 20 days prior to the date the Notice of Final Distribution is to be mailed to the affected Certificateholders, the Master Servicer shall notify the Depositor, and the Securities Administrator of (a) the date on which the Master Servicer intends to exercise such purchase option and (b) the Termination Price.

(a) The Securities Administrator on behalf of the Trustee shall sell all of the assets of the Trust Fund to the party exercising the Option to Purchase, and, within 90 days of such sale, shall distribute to the Certificateholders the proceeds of such sale in complete liquidation of each REMIC formed hereby; and

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

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).

131

Section 13.07 [Reserved.]

Section 13.08 Limitation on Rights of Certificateholders. The death or incapacity of any Certificateholder shall not operate to terminate this Agreement or the trust created hereby, nor entitle such Certificateholder’s legal representative or heirs to claim an accounting or to take any action or commence any proceeding in any court for a petition or winding up of the trust created hereby, or otherwise affect the rights, obligations and liabilities of the parties hereto or any of them.

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

No Certificateholder shall have any right by virtue or by availing itself of any provisions of this Agreement to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Agreement, unless such Holder previously shall have given to the Trustee a written notice of an Event of Default and of the continuance thereof, as herein provided, and unless the Holders of Certificates evidencing not less than 25.00% of the Voting Rights evidenced by the Certificates shall also have made written request to the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder and shall have offered to the Trustee such reasonable indemnity as it may require against the costs, expenses, and liabilities to be incurred therein or thereby, and the Trustee, for 60 days after its receipt of such notice, request and offer of indemnity shall have neglected or refused to institute any such action, suit or proceeding; it being understood and intended, and being expressly covenanted by each Certificateholder with every other Certificateholder and the Trustee, that no one or more Holders of Certificates shall have any right in any manner whatever by virtue or by availing itself or themselves of any provisions of this Agreement to affect, disturb or prejudice the rights of the Holders of any other of the Certificates, or to obtain or seek to obtain priority over or preference to any other such Holder or to enforce any right under this Agreement, except in the manner herein provided and for the common benefit of all Certificateholders. For the protection and enforcement of the provisions of this Section 13.08, each and every Certificateholder and the Trustee shall be entitled to such relief as can be given either at law or in equity.

133

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. [Include for Class [ ] - IO Certificates and Inverse Floater Certificates: The Notional Amount of the Class [ ] - IO] [Class I-A-[ ]] Certificates as of any date of determination is equal to [the aggregate Stated Principal Balance of the Mortgage Loans corresponding to the applicable Subgroup represented by such Class [ ] - IO Certificates] [the Class Certificate Balance of the Class I-A-[ ] Certificates]. The Class [[ ] - IO] [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-6

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.

HSI Asset Loan Obligation Trust 2007-1

Mortgage Pass-Through Certificates, Series 2006- [___]

STATE OF	)
	)	ss.:
COUNTY OF	)

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

1. The undersigned is an officer of ___________________, the proposed Transferee of an Ownership Interest in a Class R Certificate (the “Certificate”) issued pursuant to the Pooling and Servicing Agreement (the “Agreement”), relating to the above-referenced Series, dated as of May 1, 2007 among HSI Asset Securitization Corporation, as depositor, Xxxxx Fargo Bank, N.A., as custodian, CitiMortgage, Inc., as master servicer, Citibank, N.A., as securities administrator, and Deutsche Bank National Trust Company, as trustee. Capitalized terms used, but not defined herein, shall have the meanings ascribed to such terms in the Agreement. The Transferee has authorized the undersigned to make this affidavit on behalf of the Transferee for the benefit of the Depositor, the Securities Administrator and the Trustee.

2. The Transferee is, as of the date hereof, and will be, as of the date of the Transfer, a Permitted Transferee. The Transferee is acquiring its Ownership Interest in the Certificate for its own account. The Transferee has no knowledge that any such affidavit is false.

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

4. The Transferee has been advised of, and understands that a tax will be imposed on a “pass-through entity” holding the Certificate if at any time during the taxable year of the pass-through entity a Person that is a Non-Permitted Transferee is the record holder of an interest in such entity. The Transferee understands that such tax will not be imposed for any period with respect to which the record holder furnishes to the pass-through entity an affidavit that such record holder is a Permitted Transferee and the pass-through entity does not have actual knowledge that such affidavit is false. (For this purpose, a “pass-through entity” includes a regulated investment company, a real estate investment trust or common trust fund, a partnership, trust or estate, and certain cooperatives and, except as may be provided in Treasury Regulations, persons holding interests in pass-through entities as a nominee for another Person.)

EXHIBIT G-1

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

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

7. The Transferee does not have the intention to impede the assessment or collection of any tax legally required to be paid with respect to the Certificate. The Transferee has historically paid its debts as they have come due and intends to pay its debts as they come due in the future. The Transferee intends to pay all taxes due with respect to the Certificate as they become due.

8. The Transferee’s taxpayer identification number is __________.

9. The Transferee is not a Disqualified Non-U.S. Person as defined in the Agreement.

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

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

12. Check the applicable paragraph:

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

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

EXHIBIT G-2

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

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

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

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

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

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

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

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

o None of the above.

13. The Transferee is not an employee benefit plan that is subject to Title I of ERISA or a plan that is subject to Section 4975 of the Code or a plan subject to any Federal, state or local law that is substantially similar to Title I of ERISA or Section 4975 of the Code, and the Transferee is not acting on behalf of or investing plan assets of such a plan.
