THIS POOLING AND SERVICING AGREEMENT, dated as of January 1, 2005, among CREDIT SUISSE FIRST BOSTON MORTGAGE SECURITIES CORP., a Delaware corporation, as the depositor (the “Depositor”), DLJ MORTGAGE CAPITAL, INC., a Delaware corporation, as the Seller (the “Seller”), OCWEN FEDERAL BANK FSB, a federally chartered savings bank, as the servicer (“Ocwen” or the “Servicer”), THE MURRAYHILL COMPANY, a Colorado corporation, as credit risk manager (the “Credit Risk Manager”) and U.S. BANK NATIONAL ASSOCIATION, a national banking association, as the trustee (the “Trustee”).

WITNESSETH THAT

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

PRELIMINARY STATEMENT

As provided herein, the Trustee shall elect that the Trust Fund (exclusive of the assets held in the Basis Risk Reserve Fund, the Prefunding Account and the Capitalized Interest Account, and exclusive of any entitlement to Prepayment Premiums) be treated for federal income tax purposes as comprising three real estate mortgage investment conduits (each a “REMIC” or, in the alternative, the Pooling REMIC, the Subsidiary REMIC and the Master REMIC). Each Certificate, other than the Class R and Class P Certificate, represents ownership of a regular interest in the Master REMIC for purposes of the REMIC Provisions. In addition, each of the Class A, Class M and Class B Certificates represents the right to receive payments pursuant to contractual arrangements as described in Section 8.11 of this Agreement. The Class X Certificate also represents ownership of the assets held from time to time in the Basis Risk Reserve Fund. The Class R Certificate represents ownership of the sole class of residual interest in each of the Subsidiary REMIC and the Master REMIC for purposes of the REMIC Provisions. The Class R-II Certificate represents ownership of the sole class of residual interest in the Pooling REMIC. The Master REMIC shall hold as its assets the several classes of uncertificated Lower Tier Interests in the Subsidiary REMIC, other than the Class LT1-R Interest, and each such Lower Tier Interest is hereby designated as a regular interest in the Subsidiary REMIC. The Subsidiary REMIC shall hold as its assets the several classes of uncertificated Lower Tier Interests in the Pooling REMIC and each such Lower Tier Interest is hereby designated as a regular interest in the Pooling REMIC. The Pooling REMIC shall hold as assets the property of the Trust Fund other than the Lower Tier Interests in the Pooling REMIC and the Subsidiary REMIC, the Basis Risk Reserve Fund, the Prefunding Account, the Capitalized Interest Account and any entitlement to Prepayment Premiums. The startup day for each REMIC created hereby for purposes of the REMIC Provisions is the Closing Date. In addition, for purposes of the REMIC Provisions, the latest possible maturity date for each regular interest in each REMIC created hereby is the thirty-sixth month following month in which the Initial Mortgage Loan having the latest maturity date matures.

The Pooling REMIC

The following table sets forth (or describes) the class designation, interest rate, and initial class principal amount for each class of Pooling REMIC Lower Tier Interests.

___________________________

(1)

This Lower Tier Interest shall bear interest at a rate equal to the Net WAC Rate for the related Distribution Date, computed solely with respect to the Initial Mortgage Loans.

(2)

This interest shall have an initial principal balance equal to the aggregate of the Stated Principal Balances of the Initial Mortgage Loans as of the Cut-off Date.

(3)

This interest shall be an interest-only class. For each Distribution Date on and before the Distribution Date in May 2005 (and the related Accrual Period), this Lower Tier Interest shall be entitled to receive all interest that is payable on the Subsequent Mortgage Loans during the related Collection Period.

(4)

For each Distribution Date on and before the Distribution Date in May 2005 (and the related Accrual Period), this Lower Tier Interest shall bear no interest. Thereafter, this Lower Tier Interest shall bear interest at a rate equal to the Net WAC Rate for the related Distribution Date, computed solely with respect to the Subsequent Mortgage Loans.

(5)

This interest shall have an initial principal balance equal to the Prefunded Amount.

(6)

This interest shall be an interest-only regular interest. On each Distribution Date, it shall be entitled to receive the aggregate Excess Servicing Fee.

(7)

The Class R-II Certificate represents ownership of the sole class of residual interest in the Pooling REMIC. On each Distribution Date, amounts available for distribution in the Pooling REMIC remaining after all distributions with respect to the other Pooling REMIC Interests have been made in the manner described below shall be distributed with respect to the Class R-II Certificate.

On each Distribution Date, the Trustee shall first pay or charge as an expense of the Pooling REMIC all expenses of the Trust for such Distribution Date.

On each Distribution Date the Trustee shall distribute the remaining Interest Remittance Amount (exclusive of any amount withdrawn from the Capitalized Interest Account) with respect to each of the Lower Tier Interests in the Pooling REMIC based on the above-described interest rates.

On each Distribution Date, the Trustee shall distribute the Principal Remittance Amount with respect to the Pooling REMIC Interests as follows:

(i)

With respect to the Principal Remittance Amount relating the Initial Mortgage Loans, to the Class LTP-Initial-P&I Interest until the principal balance of such Interest is reduced to zero; and

(ii)

With respect to the Principal Remittance Amount relating the Subsequent Mortgage Loans and the Prefunded Amount, to the Class LTP-Subs-PO until the principal balance of such Subsidiary REMIC Lower Tier Interest is reduced to zero.

___________________________

(1)

The interest rate for each of these Subsidiary REMIC Lower Tier Interests with respect to any Distribution Date (and the related Accrual Period) is a per annum rate equal to the weighted average of the interest rates on the Pooling REMIC Lower Tier Interests (other than any such Interest that is an interest-only interest), which rate is referred to herein as the REMIC Maximum Rate.

(2)

This Lower Tier Interest shall have an initial principal balance equal to one half of the initial principal balance of its Corresponding Class of Certificates.

(3)

The Class LT1-Q Interest shall have an initial principal balance equal to the excess of the Aggregate Collateral Balance as of the Initial Cut-off Date over the aggregate initial principal balance of each remaining regular interest in the Subsidiary REMIC.

(4)

For each Distribution Date, the Class LT1-AIO-S Interest shall be entitled to all amounts distributed with respect to the Class LTP-AIO-S Interest.

(5)

This interest shall not have a principal balance, but shall be entitled to receive, on each Distribution Date, 100% of the interest distributable on the Class LTP-Subs-IO Interest on such Distribution Date.

(6)

The Class LT1-R Interest is the sole class of residual interest in the Subsidiary REMIC. It does not have an interest rate or a principal balance.

On each Distribution Date the Trustee shall distribute interest on the Lower Tier Interests in the Subsidiary REMIC based on the above-described interest rates, provided, however, that interest that accrues on the Class LT1-Q Interest shall be deferred in an amount necessary to make the principal distributions to the other Interests in the Subsidiary REMIC as described below. Any interest so deferred shall itself bear interest at the interest rate for the Class LT1-Q Interest.

On each Distribution Date principal shall be distributed, and Realized Losses shall be allocated, among the Lower Tier Interests in the Subsidiary REMIC in the following order of priority:

(i)

First, to the Class LT1-A-1 Interest until the principal balance of such Lower Tier Interest equals one-half of the Class Principal Balance of the Class A-1 Certificates immediately after such Distribution Date;

(ii)

Second, to the Class LT1-A-2 Interest until the principal balance of such Lower Tier Interest equals one-half of the Class Principal Balance of the Class A-2 Certificates immediately after such Distribution Date;

(iii)

Third, to the Class LT1-A-3 Interest until the principal balance of such Lower Tier Interest equals one-half of the Class Principal Balance of the Class A-3 Certificates immediately after such Distribution Date;

(iv)

Fourth, to the Class LT1-A-4 Interest until the principal balance of such Lower Tier Interest equals one-half of the Class Principal Balance of the Class A-4 Certificates immediately after such Distribution Date;

(v)

Fifth, to the Class LT1-A-5 Interest until the principal balance of such Lower Tier Interest equals one-half of the Class Principal Balance of the Class A-5 Certificates immediately after such Distribution Date;

(vi)

Sixth, to the Class LT1-M-1 Interest until its principal balance equals one-half of the Class Principal Balance of the Class M-1 Certificates immediately after such Distribution Date;

(vii)

Seventh, to the Class LT1-M-2 Interest until its principal balance equals one-half of the Class Principal Balance of the Class M-2 Certificates immediately after such Distribution Date;

(viii)

Eighth, to the Class LT1-M-3 Interest until its principal balance equals one-half of the Class Principal Balance of the Class M-3 Certificates immediately after such Distribution Date;

(ix)

Ninth, to the Class LT1-M-4 Interest until its principal balance equals one-half of the Class Principal Balance of the Class M-4 Certificates immediately after such Distribution Date;

(x)

Tenth, to the Class LT1-M-5 Interest until its principal balance equals one-half of the Class Principal Balance of the Class M-5 Certificates immediately after such Distribution Date;

(xi)

Eleventh, to the Class LT1-M-6 Interest until its principal balance equals one-half of the Class Principal Balance of the Class M-6 Certificates immediately after such Distribution Date;

(xii)

Twelfth, to the Class LT1-M-7 Interest until its principal balance equals one-half of the Class Principal Balance of the Class M-7 Certificates immediately after such Distribution Date;

(xiii)

Thirteenth, to the Class LT1-B-1 Interest until its principal balance equals one-half of the Class Principal Balance of the Class B-1 Certificates immediately after such Distribution Date;

(xiv)

Fourteenth, to the Class LT1-B-2 Interest until its principal balance equals one-half of the Class Principal Balance of the Class B-2 Certificates immediately after such Distribution Date; and

___________________________

(1)

Solely for purposes of Section 1.860G-1(a)(4)(iii) of the Treasury regulations, the Distribution Date thirty-six months following the month of the maturity date for the Initial Mortgage Loan with the latest maturity date has been designated as the “latest possible maturity date” for each Class of Certificates that represents one or more of the “regular interests” in the Master REMIC.

(2)

The rate shown above is the Pass-Through Rate for the February 2005 Distribution Date (and the related Accrual Period). The Pass-Through Rate applicable to any other Distribution Date (and the related Accrual Period) shall equal the sum of the related fixed rate of interest, or with respect to the Class A-1 Certificates, the related Certificate Index and the Certificate Margin for such Distribution Date, in each case subject to a cap equal to the Net Funds Cap, provided, however, that for purposes of the REMIC Provisions, such cap shall equal the REMIC Maximum Rate and any interest distributed at a rate in excess of such cap shall be deemed to have been paid from the Basis Risk Reserve Fund.

(3)

The Class A-IO-S Certificates are an interest only Class and for each Distribution Date the Class A-IO-S Certificates shall receive the aggregate Excess Servicing Fee. For purposes of the REMIC Provisions, the Class A-IO-S Certificates shall, for each Distribution Date, be entitled to all amounts distributed with respect to the Class LT2-AIO-S Interest.

(4)

On each Distribution Date, the Class P Certificates shall be entitled to receive all Prepayment Premiums collected or paid by the Servicer with respect to the preceding prepayment period. The Class P Certificates shall not represent an interest in any REMIC formed hereby.

(5)

The Class X Certificates shall represent ownership of three regular interests in the Master REMIC (collectively, the “Class X Interest”). The first regular interest shall have a principal balance equal to the excess of the Aggregate Collateral Balance as of the Initial Cut-off Date over the initial Certificate Principal Balance of all Certificates as of the Closing Date. This regular interest shall not bear interest. The second regular interest shall be an interest-only regular interest. Its notional amount shall for any Distribution Date (and the related Accrual Period) equal the sum of the principal balances of the Subsidiary REMIC Lower Tier Interests as of the preceding Distribution Date. For each Accrual Period, this interest-only regular interest shall accrue interest on its notional amount at a per annum rate equal to the excess of (i) the weighted average of the interest rates on the Subsidiary REMIC Lower Tier Interests (other than the Class LT1-AIO-S, Class LT1-Subs-IO and Class LT1-R Interests), over (ii) the Adjusted Subsidiary REMIC WAC. Interest accrued on this interest-only regular interest for any Accrual Period shall not be distributed on the related Distribution Date but shall be deferred to the extent of any increase in the Overcollateralization Amount for such Distribution Date. Any interest so deferred shall not itself accrue interest. The third regular interest shall be entitled to receive, on each Distribution Date, all amounts distributed on the Class LT-1-Subs-IO Interest on such Distribution Date.

(6)

The Class R Certificate represents ownership of the residual interest in the Master REMIC, as well as ownership of the residual interest in the Subsidiary REMIC.

(7)

The Class R-II Certificate represents ownership of the residual interest in the Pooling REMIC.

SECTION 2.02

Acceptance by the Trustee of the Mortgage Loans.

(a)

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

The Trustee agrees to deliver as of 10:00 a.m. (New York time) on the Closing Date to the Depositor and the Servicer an Initial Certification from the Custodian in the form annexed hereto as Exhibit G. Based on its review and examination, and only as to the documents identified in each such Initial Certification, the Custodian acknowledges that such documents appear regular on their face and relate to such Mortgage Loan. The Trustee shall be under no duty or obligation to inspect, review or examine said documents, instruments, certificates or other papers to determine that the same are genuine, enforceable or appropriate for the represented purpose or that they have actually been recorded in the real estate records or that they are other than what they purport to be on their face.

Not later than 90 days after the Closing Date, the Trustee shall deliver to the Depositor, the Seller and the Servicer a Final Certification in the form annexed hereto as Exhibit H, with any applicable exceptions noted thereon.

If, in the course of such review, the Trustee is notified by the Custodian that any document constituting a part of a Mortgage File does not meet the requirements of Section 2.01, the Trustee shall cause the Custodian to list such as an exception in the Final Certification; provided, however, that the Trustee shall not make any determination as to whether (i) any endorsement is sufficient to transfer all right, title and interest of the party so endorsing, as noteholder or assignee thereof, in and to that Mortgage Note or (ii) any assignment is in recordable form or is sufficient to effect the assignment of and transfer to the assignee thereof under the mortgage to which the assignment relates.

The Seller shall promptly correct or cure such defect within 90 days from the date it is so notified of such defect and, if the Seller does not correct or cure such defect within such period, the Seller shall either (i) substitute for the related Mortgage Loan a Qualified Substitute Mortgage Loan, which substitution shall be accomplished in the manner and subject to the conditions set forth in Section 2.03, or (ii) purchase such Mortgage Loan from the Trustee within 90 days from the date the Seller was notified of such defect in writing at the Repurchase Price of such Mortgage Loan; provided, however, that if the cure, substitution or repurchase of a Mortgage Loan pursuant to this provision is required by reason of a delay in delivery of any documents by the appropriate recording office, then the Seller shall be given 720 days from the Closing Date to cure such defect or substitute for, or repurchase such Mortgage Loan; and further provided, that the Seller shall have no liability for recording any Assignment of Mortgage in favor of the Trustee or for the Trustee’s failure to record such Assignment of Mortgage, and the Seller shall not be obligated to repurchase or cure any Mortgage Loan as to which such Assignment of Mortgage is not recorded. The Trustee shall deliver written notice to each Rating Agency within 270 days from the Closing Date indicating each Mortgage (a) which has not been returned by the appropriate recording office or (b) as to which there is a dispute as to location or status of such Mortgage. Such notice shall be delivered every 90 days thereafter until the related Mortgage is returned to the Trustee or Custodian. Any such substitution effected more than 90 days after the Closing Date shall not be effected prior to the delivery to the Trustee of the Opinion of Counsel required by Section 2.05 hereof and any substitution shall not be effected prior to the additional delivery to the Trustee, or the Custodian on its behalf, of a Request for Release substantially in the form of Exhibit M and the Mortgage File for any such Qualified Substitute Mortgage Loan. The Repurchase Price for any such Mortgage Loan shall be deposited by the Seller in the applicable Collection Account on or prior to the Business Day immediately preceding the Distribution Date in the month following the month of repurchase and, upon receipt of such deposit and certification with respect thereto in the form of Exhibit M hereto, the Trustee, or the Custodian on its behalf, shall release the related Mortgage File to the Seller and shall execute and deliver at such entity’s request such instruments of transfer or assignment prepared by such entity, in each case without recourse, as shall be necessary to vest in such entity, or a designee, the Trustee’s interest in any Mortgage Loan released pursuant hereto.

If pursuant to the preceding paragraph the Seller repurchases a Mortgage Loan that is a MERS Mortgage Loan, the Servicer shall, at the Seller’s expense, either (i) cause MERS to execute and deliver an Assignment of Mortgage in recordable form to transfer the Mortgage from MERS to the Seller and shall cause such Mortgage to be removed from registration on the MERS® System in accordance with MERS’ rules and regulations or (ii) cause MERS to designate on the MERS® System the Seller as the beneficial holder of such Mortgage Loan.

The Trustee agrees to cause the Custodian to and the Custodian shall execute and deliver prior to 10:00 a.m. (New York time) on each Subsequent Transfer Date to the Depositor and the Servicer a Subsequent Certification in the form annexed hereto as Exhibit G. Based on its review and examination, and only as to the documents identified in such Subsequent Certification, the Custodian shall acknowledge that such documents appear regular on their face and relate to such Subsequent Mortgage Loan. The Trustee shall be under no duty or obligation to inspect, review or examine said documents, instruments, certificates or other papers to determine that the same are genuine, enforceable or appropriate for the represented purpose or that they have actually been recorded in the real estate records or that they are other than what they purport to be on their face.

Not later than 90 days after the end of the Prefunding Period, the Trustee shall cause the Custodian to deliver to the Depositor, the Seller and the Servicer a Final Certification with respect to the Subsequent Mortgage Loans in the form annexed hereto as Exhibit H with any applicable exceptions noted thereon.

If, in the course of such review of the Mortgage Files relating to the Subsequent Mortgage Loans, the Custodian finds any document constituting a part of a Mortgage File which does not meet the requirements of Section 2.01, the Trustee shall cause the Custodian to list such as an exception in the Final Certification; provided, however that the Trustee shall not make any determination as to whether (i) any endorsement is sufficient to transfer all right, title and interest of the party so endorsing, as noteholder or assignee thereof, in and to that Mortgage Note or (ii) any assignment is in recordable form or is sufficient to effect the assignment of and transfer to the assignee thereof under the mortgage to which the assignment relates. The Seller shall cure any such defect or repurchase or substitute for any such Mortgage Loan in accordance with this Section 2.02(a).

(b)

It is understood and agreed that the obligation of the Seller to cure, substitute for or to repurchase any Mortgage Loan which does not meet the requirements of Section 2.01 shall constitute the sole remedy respecting such defect available to the Trustee, the Depositor and any Certificateholder against the Seller.

(c)

All of the Mortgage Files are being held pursuant to the Custodial Agreement. Notwithstanding anything to the contrary contained herein, the parties hereto acknowledge that the functions of the Trustee with respect to the custody, acceptance, inspection and release of the Mortgage Files pursuant to Sections 2.01, 2.02, 2.05 and 3.12 shall be performed by the Custodian. At the expense of DLJMC, the Trustee, from time to time, shall instruct or cause the instruction of the Custodian to deliver the Mortgage Files to the Trustee for completion and recordation of the Assignments of Mortgage.

SECTION 2.03

Representations and Warranties of the Seller and the Servicer.

(a)

Each of DLJMC and Ocwen in its capacity as Seller or Servicer, as applicable, hereby makes on behalf of themselves the representations and warranties set forth in Schedule IIA and Schedule IIB hereto, respectively, and by this reference incorporated herein, to the Depositor and the Trustee, as of the Closing Date, or if so specified therein, as of the applicable Cut-off Date.

(b)

DLJMC, in its capacity as Seller, hereby makes the representations and warranties set forth in Schedule III to the Depositor and the Trustee, as of the Closing Date, or the date specified therein, with respect to the Initial Mortgage Loans identified on Schedule I hereto and as of the Subsequent Transfer Date with respect to any Subsequent Mortgage Loan identified on Schedule I hereto. Any breach of the representation and warranty set forth in clauses (xx), (xxiii) and (xxiv) of Schedule III hereto shall be deemed to materially and adversely affect the interest of the Certificateholders in that Mortgage Loan, notwithstanding the Seller’s lack of knowledge with respect to the substance of such representation and warranty.

(c)

If any Initial Mortgage Loan less than thirty days delinquent as of the Initial Cut-off Date (i) fails to make its Scheduled Payment due during the period commencing on the second day of the month preceding the month in which the Initial Cut-off Date occurs and ending on the Initial Cut-off Date and (ii) becomes 30 days or more delinquent with respect to such Scheduled Payment, then the Seller shall be deemed to have automatically breached the representation and warranty set forth in clause (iv) of Schedule III hereto; provided, however, that in no event shall such representation and warranty be automatically breached with respect to Initial Mortgage Loans constituting more than 3% of the Aggregate Collateral Balance as of the Initial Cut-off Date (including amounts in the Prefunding Account as of the Closing Date); provided, further, however, that (1) if such representation and warranty is breached with respect to Initial Mortgage Loans exceeding such 3%, then such representation and warranty shall not be deemed automatically breached for any Initial Mortgage Loan and (2) the Seller shall not be deemed to have automatically breached such representation and warranty with respect to any Mortgage Loan for which such Scheduled Payment is made during the period commencing on the second day of the month preceding the month in which the Initial Cut-off Date occurs and ending on the close of business on February 28, 2005. The Servicer shall notify the Seller and the Trustee of any such delinquency. In connection with any such delinquency and automatic breach relating to the Initial Mortgage Loans constituting not more than 3% of the Aggregate Collateral Balance, the Seller shall be required to replace all such delinquent Initial Mortgage Loans with Qualified Substitute Mortgage Loans in accordance with the terms and provisions of Section 2.03(d) below on or before the March 2005 Distribution Date (without regard to any reference in Section 2.03(d) below to a “90-day” period). A breach may exist for purposes of Section 2.03(d), notwithstanding the non-existence of an automatic breach for purposes of this Section 2.03(c).

(d)

Upon discovery by any of the parties hereto of a breach of a representation or warranty made pursuant to Section 2.03(b) that materially and adversely affects the interests of the Certificateholders in any Mortgage Loan, the party discovering such breach shall give prompt notice thereof to the other parties. The Seller hereby covenants that within 90 days of the earlier of its discovery or its receipt of written notice from any party of a breach of any representation or warranty made by it pursuant to Section 2.03(b) which materially and adversely affects the value of the related Mortgage Loan or the interests of the Certificateholders, it shall cure such breach in all material respects, and if such breach is not so cured, shall, (i) if such 90-day period expires prior to the second anniversary of the Closing Date, remove such Mortgage Loan (a “Deleted Mortgage Loan”) from the Trust Fund and substitute in its place a Qualified Substitute Mortgage Loan, in the manner and subject to the conditions set forth in this Section; or (ii) repurchase the affected Mortgage Loan or Mortgage Loans from the Trustee at the Repurchase Price in the manner set forth below; provided, however, that any such substitution pursuant to (i) above shall not be effected prior to the delivery to the Trustee of the Opinion of Counsel required by Section 2.05 hereof, if any, and any such substitution pursuant to (i) above shall not be effected prior to the additional delivery to the Trustee of a Request for Release substantially in the form of Exhibit M and the Mortgage File for any such Qualified Substitute Mortgage Loan. The Seller shall promptly reimburse the Servicer and the Trustee for any actual out-of-pocket expenses reasonably incurred by the Servicer or the Trustee in respect of enforcing the remedies for such breach. With respect to any representation and warranty described in this Section which are made to the best of the Seller’s knowledge, if it is discovered by either the Depositor, the Seller or the Trustee that the substance of such representation and warranty is inaccurate and such inaccuracy materially and adversely affects the value of the related Mortgage Loan or the interests of the Certificateholders therein, notwithstanding the Seller’s lack of knowledge with respect to the substance of such representation or warranty, such inaccuracy shall be deemed a breach of the applicable representation or warranty.

With respect to any Qualified Substitute Mortgage Loan or Loans, the Seller shall deliver to the Trustee for the benefit of the Certificateholders the Mortgage Note, the Mortgage, the related assignment of the Mortgage, and such other documents and agreements as are required by Section 2.01(b), with the Mortgage Note endorsed and the Mortgage assigned as required by Section 2.01. Scheduled Payments due with respect to Qualified Substitute Mortgage Loans in the Collection Period related to the Distribution Date in the month of substitution shall not be part of the Trust Fund and will be retained by the Seller. For the month of substitution, distributions to Certificateholders will include the Scheduled Payment due on any Deleted Mortgage Loan for the related Collection Period and thereafter the Seller shall be entitled to retain all amounts received in respect of such Deleted Mortgage Loan. The Seller shall amend the related Mortgage Loan Schedule for the benefit of the Certificateholders to reflect the removal of such Deleted Mortgage Loan and the substitution of the Qualified Substitute Mortgage Loan or Loans and the Seller shall deliver the amended Mortgage Loan Schedule to the Trustee, the Servicer and the Depositor. Upon such substitution, the Qualified Substitute Mortgage Loan or Loans shall be subject to the terms of this Agreement in all respects, and the Seller shall be deemed to have made with respect to such Qualified Substitute Mortgage Loan or Loans, as of the date of substitution, the representations and warranties made pursuant to Section 2.03(b) with respect to such Mortgage Loan. Upon any such substitution and the deposit to the applicable Collection Account of the amount required to be deposited therein in connection with such substitution as described in the following paragraph, the Trustee shall or shall cause the applicable Custodian to release the Mortgage File held for the benefit of the Certificateholders relating to such Deleted Mortgage Loan to the Seller and shall execute and deliver at the Seller’s direction such instruments of transfer or assignment prepared by the Seller, in each case without recourse, as shall be necessary to vest title in the Seller, or its designee, the Trustee’s interest in any Deleted Mortgage Loan substituted for pursuant to this Section 2.03.

For any month in which the Seller substitutes one or more Qualified Substitute Mortgage Loans for one or more Deleted Mortgage Loans, the Servicer will determine the amount (if any) by which the aggregate principal balance of all such Qualified Substitute Mortgage Loans as of the date of substitution is less than the aggregate Stated Principal Balance of all such Deleted Mortgage Loans (after application of the scheduled principal portion of the monthly payments due in the month of substitution). The amount of such shortage (the “Substitution Adjustment Amount”) plus an amount equal to the sum of (i) the aggregate of any unreimbursed Advances with respect to such Deleted Mortgage Loans and (ii) any costs and damages actually incurred and paid by or on behalf of the Trust in connection with any breach of the representation and warranty set forth in Schedule III (xxi) as the result of a violation of a predatory or abusive lending law applicable to such Mortgage Loan shall be deposited in the applicable Collection Account by the Seller on or before the Business Day immediately preceding the related Servicer Remittance Date in the month succeeding the calendar month during which the related Mortgage Loan became required to be purchased or replaced hereunder.

One or more mortgage loans may be substituted for one or more Deleted Mortgage Loans. The determination of whether a mortgage loan is a Qualified Substitute Mortgage Loan may be satisfied on an individual basis. Alternatively, if more than one mortgage loan is to be substituted for one or more Deleted Mortgage Loans, the characteristics of such mortgage loans and Deleted Mortgage Loans shall be aggregated or calculated on a weighted average basis, as applicable, in determining whether such mortgage loans are Qualified Substitute Mortgage Loans.

In the event that the Seller shall have repurchased a Mortgage Loan, the Repurchase Price therefor shall be deposited in the related Collection Account pursuant to Section 3.06 on or before the Business Day immediately preceding the related Servicer Remittance Date in the month following the month during which the Seller became obligated hereunder to repurchase or replace such Mortgage Loan and upon such deposit of the Repurchase Price and receipt of a Request for Release in the form of Exhibit M hereto, the Trustee shall release or cause the Custodian to release the related Mortgage File held for the benefit of the Certificateholders to such Person, and the Trustee shall execute and deliver at such Person’s direction such instruments of transfer or assignment prepared by such Person, in each case without recourse, as shall be necessary to transfer title from the Trustee. It is understood and agreed that the obligation under this Agreement of any Person to cure, repurchase or substitute any Mortgage Loan as to which a breach has occurred and is continuing shall constitute the sole remedy against such Persons respecting such breach available to Certificateholders, the Depositor or the Trustee on their behalf.

The representations and warranties made pursuant to this Section 2.03 shall survive delivery of the respective Mortgage Files to the Trustee, or to the Custodian on the Trustee’s behalf, for the benefit of the Certificateholders.

SECTION 2.04

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

The Depositor hereby represents and warrants to the Trustee with respect to each Mortgage Loan that, as of the Closing Date, assuming good title has been conveyed to the Depositor, the Depositor had good title to the Mortgage Loans and Mortgage Notes, and did not encumber the Mortgage Loans during its period of ownership thereof, other than as contemplated by the Agreement.

It is understood and agreed that the representations and warranties set forth in this Section 2.04 shall survive delivery of the Mortgage Files to the Trustee, or to the Custodian on the Trustee’s behalf.

SECTION 2.05

Delivery of Opinion of Counsel in Connection with Substitutions.

(a)

Notwithstanding any contrary provision of this Agreement, no substitution pursuant to Section 2.02 shall be made more than 90 days after the Closing Date unless the Seller delivers to the Trustee an Opinion of Counsel, which Opinion of Counsel shall not be at the expense of either the Trustee or the Trust Fund, addressed to the Trustee, to the effect that such substitution will not (i) result in the imposition of the tax on “prohibited transactions” on the Trust Fund or contributions after the Startup Date, as defined in Sections 860F(a)(2) and 860G(d) of the Code, respectively, or (ii) cause any REMIC hereunder to fail to qualify as a REMIC at any time that any Certificates are outstanding.

(b)

Upon discovery by the Depositor, the Seller, the Servicer or the Trustee that any Mortgage Loan does not constitute a “qualified mortgage” within the meaning of Section 860G(a)(3) of the Code, the party discovering such fact shall promptly (and in any event within five (5) Business Days of discovery) give written notice thereof to the other parties. In connection therewith, the Trustee shall require the Seller, at the Seller’s option, to either (i) substitute, if the conditions in Section 2.03(d) with respect to substitutions are satisfied, a Qualified Substitute Mortgage Loan for the affected Mortgage Loan, or (ii) repurchase the affected Mortgage Loan within 90 days of such discovery in the same manner as it would a Mortgage Loan for a breach of representation or warranty made pursuant to Section 2.03. The Trustee shall reconvey to the Seller the Mortgage Loan to be released pursuant hereto in the same manner, and on the same terms and conditions, as it would a Mortgage Loan repurchased for breach of a representation or warranty contained in Section 2.03.

SECTION 2.06

Execution and Delivery of Certificates.

The Trustee acknowledges receipt by the Custodian on its behalf of the documents identified in the Initial Certification in the form annexed hereto as Exhibit G and the amounts required to be deposited into the Prefunding Account, the Capitalized Interest Account and the Basis Risk Reserve Fund and, concurrently with such receipt, has executed and delivered to or upon the order of the Depositor, the Certificates in authorized denominations evidencing directly or indirectly the entire ownership of the Trust Fund. The Trustee agrees to hold the Trust Fund and exercise the rights referred to above for the benefit of all present and future Holders of the Certificates and to perform the duties set forth in this Agreement according to its terms.

SECTION 2.07

REMIC Matters.

The Preliminary Statement sets forth the designations and “latest possible maturity date” for federal income tax purposes of all interests created hereby. The “Startup Day” for purposes of the REMIC Provisions shall be the Closing Date. The “tax matters person” with respect to each REMIC hereunder other than the Pooling REMIC shall be the holder of the Class R Certificate. The tax matters person with respect to the Pooling REMIC shall be the holder of the Class R-II Certificate. The Trustee on behalf of the holders of the Class R and Class R-II Certificates shall act as agent for the “tax matters person”. By its acceptance of a Class R or Class R-II Certificate, each holder thereof shall have agreed to such appointment and shall have consented to the appointment of the Trustee as its agent to act on behalf of each REMIC pursuant to the specific duties outlined herein. Each REMIC’s fiscal year shall be the calendar year.

SECTION 2.08

Covenants of the Servicer.

The Servicer hereby covenants to the Depositor and the Trustee for itself only as follows:

(a)

the Servicer shall comply in the performance of its obligations under this Agreement, in all material respects with all reasonable rules and requirements of the insurer under each Primary Insurance Policy; and

(b)

no written information, certificate of an officer, statement furnished in writing or written report delivered to the Depositor, any affiliate of the Depositor or the Trustee and prepared by the Servicer pursuant to this Agreement will contain any untrue statement of a material fact.

SECTION 2.09

Conveyance of Pooling REMIC Regular Interests and Subsidiary REMIC Regular Interests and Acceptance of Master REMIC, Respectively, by the Trustee; Issuance of Certificates.

(a)

The Depositor, concurrently with the execution and delivery hereof, does hereby transfer, assign, set over and otherwise convey in trust to the Trustee without recourse all the right, title and interest of the Depositor in and to the Lower Tier Interest in the Pooling REMIC and Subsidiary REMICs for the benefit of the holders of the Certificates. The Trustee acknowledges receipt of such Lower Tier Interests (all of which are uncertificated) and declares that it holds and will hold the same in trust for the exclusive use and ultimate benefit of the holders of the Certificates. The interests evidenced by the Class R Certificate, together with the Regular Certificates (other than the Class P Certificates), constitute the entire beneficial ownership interest in the Master REMIC.

(b)

Concurrently with (i) the assignment and delivery to the Trustee of the Pooling REMIC and the Subsidiary REMIC and the acceptance by the Trustee thereof, pursuant to Section 2.01, Section 2.02 and Section 2.09(a) and (ii) the assignment and delivery to the Trustee of the Master REMIC (including the residual interest therein represented by the Class R Certificate) and the acceptance by the Trustee thereof, the Trustee, pursuant to the written request of the Depositor executed by an officer of the Depositor, has executed, authenticated and delivered to or upon the order of the Depositor, the Class R and Class R-II Certificates in authorized denominations evidencing the residual interest in the Pooling REMIC, in the case of the Class R-II Certificates, and the residual interest in the Subsidiary REMIC and the Master REMIC, in the case of the Class R Certificates.

ARTICLE III

ADMINISTRATION AND SERVICING

OF MORTGAGE LOANS

SECTION 3.01

Servicer to Service Mortgage Loans.

For and on behalf of the Certificateholders, the Servicer shall service and administer the Mortgage Loans in accordance with the terms of this Agreement and with Accepted Servicing Practices. In connection with such servicing and administration of the Mortgage Loans, the Servicer shall have full power and authority, acting alone and/or through Subservicers as provided in Section 3.02 hereof, to do or cause to be done any and all things that it may deem necessary or desirable in connection with such servicing and administration, including but not limited to, the power and authority, subject to the terms hereof (i) to execute and deliver, on behalf of the Certificateholders and the Trustee, customary consents or waivers and other instruments and documents, (ii) to consent to transfers of any Mortgaged Property and assumptions of the Mortgage Notes and related Mortgages (but only in the manner provided in this Agreement), (iii) to collect any Insurance Proceeds, other Liquidation Proceeds and other Recoveries and (iv) to effectuate foreclosure or other conversion of the ownership of the Mortgaged Property securing any Mortgage Loan, provided that the Servicer shall not take any action that is inconsistent with or prejudices the interests of the Trust Fund or the Certificateholders in any Mortgage Loan or the rights and interests of the Depositor, the Trustee or the Certificateholders under this Agreement. The Servicer shall represent and protect the interests of the Trust Fund in the same manner as it protects its own interests in mortgage loans in its own portfolio in any claim, proceeding or litigation regarding a Mortgage Loan, and shall not make or permit any modification, waiver or amendment of any Mortgage Loan which would cause any REMIC hereunder to fail to qualify as a REMIC or result in the imposition of any tax under Section 860F(a) or Section 860G(d) of the Code. Without limiting the generality of the foregoing, the Servicer, in its own name or in the name of the Depositor and the Trustee, in the Servicer’s full discretion, is hereby authorized and empowered by the Depositor and the Trustee and granted a limited power of attorney by the Trustee, when the Servicer believes it appropriate in its reasonable judgment, to execute and deliver, on behalf of the Trustee, the Depositor, the Certificateholders or any of them, any and all instruments of satisfaction or cancellation, or of partial or full release or discharge and all other comparable instruments, with respect to to the Mortgaged Properties and the Mortgage Loans held for the benefit of the Certificateholders. The Servicer shall prepare and deliver to the Depositor and/or the Trustee such documents requiring execution and delivery by either or both of them as are necessary or appropriate to enable the Servicer to service and administer the Mortgage Loans to the extent that the Servicer is not permitted to execute and deliver such documents pursuant to the preceding sentence. Upon receipt of such documents, the Depositor and/or the Trustee shall execute such documents and deliver them to the Servicer.

In accordance with the standards of the preceding paragraph, the Servicer shall advance or cause to be advanced funds as necessary for the purpose of effecting the payment of taxes and assessments on the Mortgaged Properties, which advances shall constitute Servicing Advances and shall be reimbursable in the first instance from related collections from the Mortgagors pursuant to Section 3.06, and further as provided in Section 3.09. The costs incurred by the Servicer, if any, in effecting the timely payments of taxes and assessments on the Mortgaged Properties and related insurance premiums shall not, for the purpose of calculating monthly distributions to the Certificateholders, be added to the Stated Principal Balances of the related Mortgage Loans, notwithstanding that the terms of such Mortgage Loans so permit. The parties to this Agreement acknowledge that Servicing Advances shall be reimbursable pursuant to Section 3.09 and agree that no Servicing Advances shall be rejected or disallowed by any party unless such Servicing Advance is not reimbursable under the terms of this Agreement.

The Servicer agrees that for each Mortgage Loan it shall fully furnish, in accordance with the Fair Credit Reporting Act and its implementing regulations, accurate and complete information on its borrower credit files to Equifax, Experian and Trans Union Credit Information Company on a monthly basis.

The Servicer hereby acknowledges that, to the extent it has previously serviced some or all of the Mortgage Loans pursuant to another servicing agreement, the provisions contained in this Agreement shall supersede the provisions contained in such other servicing agreement.

The Servicer is authorized and empowered by the Trustee, on behalf of the Certificateholders and the Trustee, in its own name or in the name of any Subservicer, when the Servicer or any Subservicer, as the case may be, believes it appropriate in its best judgment to register any Mortgage Loan on the MERS® System, or cause the removal from the registration of any Mortgage Loan on the MERS® System, to execute and deliver, on behalf of the Trustee and the Certificateholders or any of them, any and all instruments of assignment and other comparable instruments with respect to such assignment or re-recording of a Mortgage in the name of MERS, solely as nominee for the Trustee and its successors and assigns.

SECTION 3.02

Subservicing; Enforcement of the Obligations of Subservicers.

(a)

The Mortgage Loans may be subserviced by a Subservicer on behalf of the Servicer in accordance with the servicing provisions of this Agreement, provided that the Subservicer is a FNMA-approved lender or a FHLMC seller/servicer in good standing, and no event has occurred, including but not limited to a change in insurance coverage, which would make it unable to comply with the eligibility requirements for lenders imposed by FNMA or for seller/servicer imposed by FHLMC, or which would require notification to FNMA or FHLMC. The Servicer may perform any of its servicing responsibilities hereunder or may cause the Subservicer to perform any such servicing responsibilities on its behalf, but the use by the Servicer of a Subservicer shall not release the Servicer from any of its obligations hereunder and the Servicer shall remain responsible hereunder for all acts and omissions of a Subservicer as fully as if such acts and omissions were those of the Servicer. The Servicer shall pay all fees and expenses of any Subservicer engaged by the Servicer from its own funds.

Notwithstanding the foregoing, the Servicer shall be entitled to outsource one or more separate servicing functions to a Person (each, an “Outsourcer”) that does not meet the eligibility requirements for a Subservicer, so long as such outsourcing does not constitute the delegation of the Servicer’s obligation to perform all or substantially all of the servicing to such Outsourcer. In such event, the use by the Servicer of any such Outsourcer shall not release the Servicer from any of its obligations hereunder and the Servicer shall remain responsible hereunder for all acts and omissions of such Outsourcer as fully as if such acts and omissions were those of the Servicer, and the Servicer shall pay all fees and expenses of the Outsourcer from theServicer’s own funds.

(b)

At the cost and expense of the Servicer, without any right of reimbursement from the Depositor, Trustee, or the applicable Collection Account, the Servicer shall be entitled to terminate the rights and responsibilities of its Subservicer and arrange for any servicing responsibilities to be performed by a successor Subservicer meeting the requirements set forth in Section 3.02(a); provided, however, that nothing contained herein shall be deemed to prevent or prohibit the Servicer, at the Servicer’s option, from electing to service the Mortgage Loans itself. In the event that the Servicer’s responsibilities and duties under this Agreement are terminated pursuant to Section 7.01, and if requested to do so by the Trustee, the Servicer shall at its own cost and expense terminate the rights and responsibilities of its Subservicer as soon as is reasonably possible. The Servicer shall pay all fees, expenses or penalties necessary in order to terminate the rights and responsibilities of its Subservicer from the Servicer’s own funds without any right of reimbursement from the Depositor, Trustee, or the applicable Collection Account.

(c)

Notwithstanding any of the provisions of this Agreement relating to agreements or arrangements between the Servicer and its Subservicer, the Servicer and its Outsourcer, or any reference herein to actions taken through the Subservicer, the Outsourcer, or otherwise, the Servicer shall not be relieved of its obligations to the Depositor, Trustee or Certificateholders and shall be obligated to the same extent and under the same terms and conditions as if it alone were servicing and administering the Mortgage Loans. The Servicer shall be entitled to enter into an agreement with its Subservicer and Outsourcer for indemnification of the Servicer by such Subservicer or Outsourcer, as applicable, and nothing contained in this Agreement shall be deemed to limit or modify such indemnification.

For purposes of this Agreement, the Servicer shall be deemed to have received any collections, recoveries or payments with respect to the related Mortgage Loans that are received by a related Subservicer or Outsourcer regardless of whether such payments are remitted by the Subservicer or Outsourcer to the Servicer.

Any Subservicing Agreement and any other transactions or services relating to the Mortgage Loans involving a Subservicer shall be deemed to be between the Subservicer and the Servicer alone, and the Depositor, the Trustee shall have no obligations, duties or liabilities with respect to a Subservicer including no obligation, duty or liability to pay a Subservicer’s fees and expenses.

In the event that the Servicer shall for any reason no longer be the Servicer hereunder (including by reason of an Event of Default, as defined in Section 7.01 herein), the Trustee or its successor shall thereupon assume all of the rights and obligations of the Servicer hereunder arising thereafter (except that the Trustee shall not be (i) liable for losses of the Servicer pursuant to Section 3.10 hereof or any acts or omissions of the related predecessor Servicer hereunder, (ii) obligated to make Advances if it is prohibited from doing so by applicable law, (iii) obligated to effectuate repurchases or substitutions of Mortgage Loans hereunder including, but not limited to, repurchases or substitutions of Mortgage Loans pursuant to Section 2.02 or 2.03 hereof or (iv) deemed to have made any representations and warranties of the Servicer hereunder). Any such assumption shall be subject to Section 7.02 hereof.

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

SECTION 3.06

Collection of Mortgage Loans; Collection Account; Certificate Account; Prefunding Account; Capitalized Interest Account.

(a)

Continuously from the date hereof until the principal and interest on Mortgage Loans have been paid in full or such Mortgage Loans have become Liquidation Mortgage Loans, the Servicer shall proceed in accordance with the customary and usual standards of practice of prudent mortgage loan servicers to collect all payments due under each of the Mortgage Loans when the same shall become due and payable to the extent consistent with this Agreement and any related Primary Insurance Policy and shall take special care with respect to Mortgage Loans for which the Servicer collects escrow payments in ascertaining and estimating Escrow Payments and all other charges that will become due and payable with respect to the Mortgage Loans and the Mortgaged Properties, to the end that the installments payable by the Mortgagors will be sufficient to pay such charges as and when they become due and payable. Consistent with the foregoing, in connection with the Mortgage Loans, the Servicer may in its discretion (i) waive any late payment charge and (ii) extend the due dates for payments due on a Mortgage Note for a period not greater than 180 days; provided, however, that the Servicer cannot extend the maturity of any such Mortgage Loan past the date on which the final payment is due on the latest maturing Mortgage Loan as of the Cut-off Date. In the event of any such arrangement, the Servicer shall make Advances on the related Mortgage Loan in accordance with the provisions of Section 4.01 during the scheduled period in accordance with the amortization schedule of such Mortgage Loan without modification thereof by reason of such arrangements. The Servicer shall not be required to institute or join in litigation with respect to collection of any payment (whether under a Mortgage, Mortgage Note or otherwise or against any public or governmental authority with respect to a taking or condemnation) if it reasonably believes that enforcing the provision of the Mortgage or other instrument pursuant to which such payment is required is prohibited by applicable law.

(b)

The Servicer shall segregate and hold all funds collected and received pursuant to Section 3.06(a) separate and apart from any of its own funds and general assets and shall establish and maintain one or more Collection Accounts, in the form of time deposit or demand accounts, titled “[Servicer’s name], as servicer for U.S. Bank National Association, as trustee, in trust for the Holders of CSFB Home Equity Pass-Through Certificates, Series 2005-FIX1 Trust, CSFB Home Equity Pass-Through Certificates, Series 2005-FIX1”, wherein the Servicer will have access to such Collection Accounts. Each Collection Account shall be an Eligible Account. Any funds deposited in a Collection Account shall at all times be either invested in Eligible Investments or shall be fully insured to the full extent permitted under applicable law. Funds deposited in a Collection Account may be drawn on by the Servicer in accordance with Section 3.09.

(c)

The Servicer shall deposit in the applicable Collection Account on a daily basis within two (2) Business Days following receipt, and, in each case, retain therein, the following collections remitted by Subservicers or payments received by the Servicer and payments made by the Servicer subsequent to the Initial Cut-off Date (or, with respect to Subsequent Mortgage Loans, the applicable Subsequent Cut-off Dates), other than payments of principal and interest due on or before the applicable Cut-off Date:

(i)

all payments on account of principal on the Mortgage Loans, including all Principal Prepayments;

(ii)

all payments on account of interest on the Mortgage Loans adjusted to the per annum rate equal to the Mortgage Rate reduced by the Servicing Fee Rate;

(iii)

all Liquidation Proceeds on the Mortgage Loans;

(iv)

all Insurance Proceeds on the Mortgage Loans including amounts required to be deposited pursuant to Section 3.10 (other than proceeds to be held in the Escrow Account and applied to the restoration or repair of the Mortgaged Property or released to the Mortgagor in accordance with Section 3.10);

(v)

all Advances made by theServicer pursuant to Section 4.01;

(vi)

all Substitution Adjustment Amounts and Repurchase Prices on the Mortgage Loans;

(vii)

with respect to each Principal Prepayment on the Mortgage Loans, the Prepayment Interest Shortfall, if any, for the Prepayment Period. The aggregate of such deposits shall be made from the Servicer’s own funds, without reimbursement therefor, up to a maximum amount per month equal to the Compensating Interest Payment, if any, for the Mortgage Loans and Distribution Date;

(viii)

any amounts required to be deposited by the Servicer in respect of net monthly income from REO Property relating to Mortgage Loans pursuant to Section 3.12; and

(ix)

any other amounts required to be deposited hereunder.

In addition, notwithstanding the provisions of this Section 3.06, the Servicer may deduct from amounts received by it, prior to deposit to the applicable Collection Account, any portion of any Scheduled Payment representing the Servicing Fee. In the event that the Servicer shall remit any amount not required to be remitted, it may at any time withdraw or direct the institution maintaining the related Collection Account to withdraw such amount from such Collection Account, any provision herein to the contrary notwithstanding. Such withdrawal or direction may be accomplished by delivering written notice thereof to the Trustee or such other institution maintaining such Collection Account which describes the amounts deposited in error in such Collection Account. The Trustee may conclusively rely on such notice and shall have no liability in connection with the withdrawal of such funds at the direction of the Servicer. The Servicer shall maintain adequate records with respect to all withdrawals made by it pursuant to this Section. All funds deposited in a Collection Account shall be held in trust for the Certificateholders until withdrawn in accordance with Section 3.09(a).

All funds deposited in the Certificate Account shall be held by the Trustee in trust for the Certificateholders until disbursed in accordance with this Agreement or withdrawn in accordance with Section 3.09(b). In no event shall the Trustee incur liability for withdrawals from the Certificate Account at the direction of the Servicer.

The Trustee in its fiduciary capacity shall not be liable for the amount of any loss incurred in respect of any investment or lack of investment of funds held in a Collection Account or the Prefunding Account (other than as provided in this Section 3.06(e)) and made in accordance with this Section 3.06.

(f)

The Servicer shall give notice to the Trustee, each Rating Agency and the Depositor of any proposed change of the location of the related Collection Account prior to any change thereof.

If any funds remain in the Prefunding Account on April 22, 2005, to the extent that they represent earnings on the amounts originally deposited into the Prefunding Account, the Trustee shall distribute them to the order of the Depositor. The remaining funds shall be transferred to the Certificate Account to be included as part of principal distributions to the Certificates on the April 2005 Distribution Date.

(h)

SECTION 3.10

Maintenance of Hazard Insurance; Mortgage Impairment Insurance and Primary Insurance Policy; Claims; Restoration of Mortgaged Property.

(a)

The Servicer shall cause to be maintained for each Mortgage Loan hazard insurance such that all buildings upon the Mortgaged Property are insured by a generally acceptable insurer rated either: “V:B” or better in the current Best’s Key Rating Guide (“Best’s”) or acceptable to FNMA and/or FHLMC against loss by fire, hazards of extended coverage and such other hazards as are customary in the area where the Mortgaged Property is located, in an amount which is at least equal to the lesser of (i) the maximum insurable value of the improvements securing such Mortgage Loan and (ii) the greater of (A) the outstanding principal balance of the Mortgage Loan and (B) an amount such that the proceeds of such policy shall be sufficient to prevent the Mortgagor and/or the mortgagee from becoming a co-insurer.

If upon origination of the Mortgage Loan, the related Mortgaged Property was located in an area identified in the Federal Register by the Flood Emergency Management Agency as having special flood hazards (and such flood insurance has been made available), the Servicer shall cause a flood insurance policy to be maintained with respect to such Mortgage Loan. Such policy shall meet the requirements of the current guidelines of the Federal Insurance Administration and be in an amount representing coverage equal to the lesser of (i) the minimum amount required, under the terms of coverage, to compensate for any damage or loss on a replacement cost basis (or the unpaid principal balance of the mortgage if replacement cost coverage is not available for the type of building insured) and (ii) the maximum amount of insurance which is available under the Flood Disaster Protection Act of 1973, as amended. If at any time during the term of the Mortgage Loan, the Servicer determines in accordance with applicable law and pursuant to the FNMA Guides that a Mortgaged Property is located in a special flood hazard area and is not covered by flood insurance or is covered in an amount less than the amount required by the Flood Disaster Protection Act of 1973, as amended, the Servicer shall notify the related Mortgagor that the Mortgagor must obtain such flood insurance coverage, and if said Mortgagor fails to obtain the required flood insurance coverage within 45 days after such notification, the Servicer shall immediately force place the required flood insurance on the Mortgagor’s behalf.

If a Mortgage Loan is secured by a unit in a condominium project, the Servicer shall verify that the coverage required of the owner’s association, including hazard, flood, liability, and fidelity coverage, is being maintained in accordance with the then current FNMA or FHLMC requirements, and secure from the owner’s association its agreement to notify the Servicer promptly of any change in the insurance coverage or of any condemnation or casualty loss that may have a material effect on the value of the related Mortgaged Property as security.

The Servicer shall cause to be maintained on each Mortgaged Property related to a Mortgage Loan such other additional special hazard insurance as may be required pursuant to such applicable laws and regulations as shall at any time be in force and as shall require such additional insurance, or pursuant to the requirements of any Primary Insurance Policy insurer, or as may be required to conform with Accepted Servicing Practices.

All policies required hereunder shall name the Servicer as loss payee and shall be endorsed with standard or union mortgagee clauses, without contribution, which shall provide for prior written notice of any cancellation, reduction in amount or material change in coverage.

The Servicer shall not interfere with the Mortgagor’s freedom of choice at the origination of such Mortgage Loan in selecting either his insurance carrier or agent, provided, however, that the Servicer shall not accept any such insurance policies from insurance companies unless such companies are rated V:B in Best’s or are acceptable to FNMA and/or FHLMC and are licensed to do business in the jurisdiction in which the Mortgaged Property is located. The Servicer shall determine that such policies provide sufficient risk coverage and amounts, that they insure the property owner, and that they properly describe the property address.

Pursuant to Section 3.06, any amounts collected by the Servicer under any such policies (other than amounts to be deposited in the related Escrow Account and applied to the restoration or repair of the related Mortgaged Property, or property acquired in liquidation of the Mortgage Loan, or to be released to the Mortgagor, in accordance with the Servicer’s normal servicing procedures) shall be deposited in the related Collection Account (subject to withdrawal pursuant to Section 3.09(a)).

Any cost incurred by the Servicer in maintaining any such insurance shall not, for the purpose of calculating monthly distributions to the Certificateholders or remittances to the Trustee for their benefit, be added to the principal balance of the Mortgage Loan, notwithstanding that the terms of the Mortgage Loan so permit. Such costs shall be recoverable by the Servicer out of late payments by the related Mortgagor or out of Liquidation Proceeds or otherwise pursuant to Section 3.09(a) hereof. It is understood and agreed that no earthquake or other additional insurance is to be required of any Mortgagor related to a Mortgage Loan or maintained on property acquired in respect of a Mortgage related to a Mortgage Loan other than pursuant to such applicable laws and regulations as shall at any time be in force and as shall require such additional insurance.

(b)

In the event that the Servicer shall obtain and maintain a blanket policy insuring against losses arising from fire and hazards covered under extended coverage on all of the Mortgage Loans, then, to the extent such policy provides coverage in an amount equal to the amount required pursuant to Section 3.10(a) and otherwise complies with all other requirements of Section 3.10(a), it shall conclusively be deemed to have satisfied its obligations as set forth in Section 3.10(a). Any amounts collected by the Servicer under any such policy relating to a Mortgage Loan shall be deposited in the related Collection Account subject to withdrawal pursuant to Section 3.09(a). Such policy may contain a deductible clause, in which case, in the event that there shall not have been maintained on the related Mortgaged Property a policy complying with Section 3.10(a), and there shall have been a loss which would have been covered by such policy, the Servicer shall deposit in the related Collection Account at the time of such loss the amount not otherwise payable under the blanket policy because of such deductible clause, such amount to be deposited from the Servicer’s funds, without reimbursement therefor. In connection with its activities as Servicer of the Mortgage Loans, the Servicer agrees to present, on behalf of itself, the Depositor, and the Trustee for the benefit of the Certificateholders, claims under any such blanket policy.

(c)

With respect to each Mortgage Loan with a Loan-to-Value Ratio in excess of 80% which the Seller represented to be covered by a Primary Insurance Policy as of the Cut-off Date and as reflected on the Mortgage Loan Schedule, the Servicer shall, without any cost to the Depositor or Trustee, maintain or cause the Mortgagor to maintain in full force and effect a Mortgage Guaranty Insurance Policy insuring that portion of the Mortgage Loan in excess of 75% of value, and shall pay or shall cause the related Mortgagor to pay, the premium thereon on a timely basis, until the loan-to-value ratio of such Mortgage Loan is reduced to 80%, based on either (i) a current appraisal of the Mortgaged Property or (ii) the appraisal of the Mortgaged Property obtained at the time the Mortgage Loan was originated. In the event that such Primary Insurance Policy shall be terminated, the Servicer shall obtain from another Qualified Insurer a comparable replacement policy, with a total coverage equal to the remaining coverage of such terminated Primary Insurance Policy. If the insurer shall cease to be a Qualified Insurer, the Servicer shall determine whether recoveries under the Primary Insurance Policy are jeopardized for reasons related to the financial condition of such insurer, it being understood that the Servicer shall in no event have any responsibility or liability for any failure to recover under the Primary Insurance Policy for such reason. If the Servicer determines that recoveries are so jeopardized, it shall notify the related Mortgagor, if required, and obtain from another Qualified Insurer a replacement insurance policy. The Servicer shall not take any action which would result in noncoverage under any applicable Primary Insurance Policy of any loss which, but for the actions of the Servicer would have been covered thereunder. In connection with any assumption or substitution agreement entered into or to be entered into pursuant to Section 3.11, the Servicer shall promptly notify the insurer under the related Primary Insurance Policy, if any, of such assumption or substitution of liability in accordance with the terms of such Primary Insurance Policy and shall take all actions which may be required by such insurer as a condition to the continuation of coverage under such Primary Insurance Policy provided that such required actions are in compliance with all applicable law. If such Primary Insurance Policy is terminated as a result of such assumption or substitution of liability, the Servicer shall obtain a replacement Primary Insurance Policy as provided above; provided that under applicable law and the terms of the related Mortgage Note and Mortgage the cost of such policy may be charged to the successor Mortgagor.

With respect to each Mortgage Loan covered by a lender paid Primary Insurance Policy, if any, the Servicer agrees to effect timely payment of the premiums on such Primary Insurance Policy from amounts on deposit in the Collection Account with respect to such Mortgage Loan. If amounts on deposit in the Collection Account with respect to such Mortgage Loan are not sufficient to pay the premiums on such Primary Insurance Policy, the Servicer agrees to effect timely payment of such premiums, and such costs shall be recoverable by the Servicer from the related Liquidation Proceeds or otherwise as a Servicing Advance pursuant to Section 3.09(a). With respect to each Mortgage Loan covered by a Primary Insurance Policy that is not lender paid, the Servicer agrees to effect timely payment of the premiums on such Primary Insurance Policy, and such costs not otherwise recoverable from the Mortgagor shall be recoverable by the Servicer from the related Liquidation Proceeds or otherwise as a Servicing Advance pursuant to Section 3.09(a).

In connection with its activities as servicer, the Servicer agrees to prepare and present, on behalf of itself, the Depositor, the Trustee and the Certificateholders, claims to the insurer under any Primary Insurance Policy in a timely fashion in accordance with the terms of such Primary Insurance Policy and, in this regard, to take such reasonable action as shall be necessary to permit recovery under any Primary Insurance Policy respecting defaulted Mortgage Loans. Pursuant to Section 3.06, any amounts collected by the Servicer under any Primary Insurance Policy shall be deposited in the related Collection Account, subject to withdrawal pursuant to Section 3.09.

(d)

[Reserved]

(e)

With respect to any Mortgage Loan, the Servicer need not obtain the approval of the Trustee prior to releasing any Insurance Proceeds to the related Mortgagor to be applied to the restoration or repair of the related Mortgaged Property if such release is in accordance with Accepted Servicing Practices. At a minimum, the Servicer shall comply with the following conditions in connection with any such release of Insurance Proceeds:

(i)

the Servicer shall receive satisfactory independent verification of completion of repairs and issuance of any required approvals with respect thereto;

(ii)

the Servicer shall take all steps necessary to preserve the priority of the lien of the Mortgage, including, but not limited to requiring waivers with respect to mechanics’ and materialmen’s liens; and

(iii)

pending repairs or restoration, the Servicer shall place the Insurance Proceeds in the related Escrow Account.

With respect to any Mortgage Loan, if the Trustee is named as an additional loss payee, the Servicer is hereby empowered to endorse any loss draft issued in respect of such a claim in the name of the Trustee.

SECTION 3.11

Enforcement of Due-on-Sale Clauses; Assumption Agreements.

(a)

With respect to any Mortgage Loan, the Servicer shall use its best efforts to enforce any “due-on-sale” provision contained in any related Mortgage or Mortgage Note and to deny assumption by the person to whom the Mortgaged Property has been or is about to be sold whether by absolute conveyance or by contract of sale, and whether or not the Mortgagor remains liable on the Mortgage and the Mortgage Note. When the Mortgaged Property has been conveyed by the Mortgagor, the Servicer shall, to the extent it has knowledge of such conveyance, exercise its rights to accelerate the maturity of such Mortgage Loan under the “due-on-sale” clause applicable thereto, provided, however, that theServicer shall not exercise such rights if prohibited by law from doing so or if the exercise of such rights would impair or threaten to impair any recovery under the related Primary Insurance Policy, if any.

(b)

With respect to any Mortgage Loan, if the Servicer reasonably believes it is unable under applicable law to enforce such “due-on-sale” clause, the Servicer shall enter into (i) an assumption and modification agreement with the person to whom such property has been conveyed, pursuant to which such person becomes liable under the Mortgage Note and the original Mortgagor remains liable thereon or (ii) in the event the Servicer is unable under applicable law to require that the original Mortgagor remain liable under the Mortgage Note, a substitution of liability agreement with the purchaser of the Mortgaged Property pursuant to which the original Mortgagor is released from liability and the purchaser of the Mortgaged Property is substituted as Mortgagor and becomes liable under the Mortgage Note. Notwithstanding the foregoing, the Servicer shall not be deemed to be in default under this Section by reason of any transfer or assumption which the Servicer reasonably believes it is restricted by law from preventing, for any reason whatsoever. In connection with any such assumption, no material term of the Mortgage Note, including without limitation, the Mortgage Rate borne by the related Mortgage Note, the term of the Mortgage Loan or the outstanding principal amount of the Mortgage Loan shall be changed.

(c)

To the extent that any Mortgage Loan is assumable, the Servicer shall inquire diligently into the creditworthiness of the proposed transferee, and shall use the underwriting criteria for approving the credit of the proposed transferee customarily used by the Servicer for the servicing of similar mortgage loans. If the credit of the proposed transferee does not meet such underwriting criteria, the Servicer diligently shall, to the extent permitted by the Mortgage or the Mortgage Note and by applicable law, accelerate the maturity of the Mortgage Loan.

(d)

With respect to any Mortgage Loan, subject to the Servicer’s duty to enforce any due-on-sale clause to the extent set forth in this Section 3.11, in any case in which a Mortgaged Property has been conveyed to a Person by a Mortgagor, and such Person is to enter into an assumption agreement or modification agreement or supplement to the Mortgage Note or Mortgage that requires the signature of the Trustee, or if an instrument of release signed by the Trustee is required releasing the Mortgagor from liability on the Mortgage Loan, the Servicer shall prepare and deliver or cause to be prepared and delivered to the Trustee for signature and shall direct, in writing, the Trustee to execute the assumption agreement with the Person to whom the Mortgaged Property is to be conveyed and such modification agreement or supplement to the Mortgage Note or Mortgage or other instruments as are reasonable or necessary to carry out the terms of the Mortgage Note or Mortgage or otherwise to comply with any applicable laws regarding assumptions or the transfer of the Mortgaged Property to such Person. In connection with any such assumption, no material term of the Mortgage Note may be changed. Together with each such substitution, assumption or other agreement or instrument delivered to the Trustee for execution by it, the Servicer shall deliver an Officer’s Certificate signed by a Servicing Officer stating that the requirements of this subsection have been met in connection therewith. The Servicer shall notify the Trustee that any such substitution or assumption agreement has been completed by forwarding to the Trustee the original of such substitution or assumption agreement, which in the case of the original shall be added to the related Mortgage File and shall, for all purposes, be considered a part of such Mortgage File to the same extent as all other documents and instruments constituting a part thereof. Any fee collected by the Servicer for entering into an assumption or substitution of liability agreement will be retained by the Servicer as additional servicing compensation.

SECTION 3.12

Realization Upon Defaulted Mortgage Loans; Repurchase of Certain Mortgage Loans.

(a)

The Servicer shall use reasonable efforts to foreclose upon or otherwise comparably convert the ownership of properties securing such of the Mortgage Loans as come into and continue in default and as to which no satisfactory arrangements can be made for collection of delinquent payments. In connection with such foreclosure or other conversion, the Servicer shall take such action as (i) the Servicer would take under similar circumstances with respect to a similar mortgage loan held for its own account for investment, (ii) shall be consistent with Accepted Servicing Practices, (iii) the Servicer shall determine consistently with Accepted Servicing Practices to be in the best interest of the Depositor, Trustee and Certificateholders, and (iv) is consistent with the requirements of the insurer under any Required Insurance Policy; provided, however, that the Servicer shall not be required to expend its own funds in connection with any foreclosure or towards the restoration of any property unless it shall determine (i) that such restoration and/or foreclosure will increase the proceeds of liquidation of the related Mortgage Loan after reimbursement to itself of such expenses and (ii) that such expenses will be recoverable to it through Liquidation Proceeds (respecting which it shall have priority for purposes of withdrawals from the related Collection Account). The Servicer shall be responsible for all other costs and expenses incurred by it in any such proceedings; provided, however, that it shall be entitled to reimbursement thereof from the Liquidation Proceeds with respect to the related Mortgaged Property or otherwise pursuant to Section 3.09(a).

With respect to any Mortgage Loan, notwithstanding anything to the contrary contained in this Agreement, in connection with a foreclosure or acceptance of a deed in lieu of foreclosure, in the event the Servicer has reasonable cause to believe that a Mortgaged Property is contaminated by hazardous or toxic substances or wastes, or if the Trustee otherwise requests, an environmental inspection or review of such Mortgaged Property conducted by a qualified inspector shall be arranged for by the Servicer. Upon completion of the inspection, the Servicer shall promptly provide the Trustee and the Credit Risk Manager with a written report of environmental inspection.

In the event the environmental inspection report indicates that the Mortgaged Property is contaminated by hazardous or toxic substances or wastes, the Servicer shall not proceed with foreclosure or acceptance of a deed in lieu of foreclosure if the estimated costs of the environmental clean up, as estimated in the environmental inspection report, together with the Servicing Advances made by the Servicer and the estimated costs of foreclosure or acceptance of a deed in lieu of foreclosure exceeds the estimated value of the Mortgaged Property. If however, the aggregate of such clean up and foreclosure costs and Servicing Advances as estimated in the environmental inspection report are less than or equal to the estimated value of the Mortgaged Property, then the Servicer may, in its reasonable judgment and in accordance with Accepted Servicing Practices, choose to proceed with foreclosure or acceptance of a deed in lieu of foreclosure and the Servicer shall be reimbursed for all reasonable costs associated with such foreclosure or acceptance of a deed in lieu of foreclosure and any related environmental clean up costs, as applicable, from the related Liquidation Proceeds, or if the Liquidation Proceeds are insufficient to fully reimburse the Servicer, the Servicer shall be entitled to be reimbursed from amounts in the related Collection Account pursuant to Section 3.09(a) hereof. In the event the Servicer does not proceed with foreclosure or acceptance of a deed in lieu of foreclosure pursuant to the first sentence of this paragraph, the Servicer shall be reimbursed for all Servicing Advances made with respect to the related Mortgaged Property from the related Collection Account pursuant to Section 3.09(a) hereof, and the Servicer shall have no further obligation to service such Mortgage Loan under the provisions of this Agreement.

(b)

With respect to any REO Property related to a Mortgage Loan, the deed or certificate of sale shall be taken in the name of the Trustee for the benefit of the Certificateholders, or its nominee, on behalf of the Certificateholders. The Trustee’s name shall be placed on the title to such REO Property solely as the Trustee hereunder and not in its individual capacity. The Servicer shall ensure that the title to such REO Property references this Agreement and the Trustee’s capacity hereunder. Pursuant to its efforts to sell such REO Property, the Servicer shall, in accordance with Accepted Servicing Practices, manage, conserve, protect and operate each REO Property for the purpose of its prompt disposition and sale. The Servicer, either itself or through an agent selected by the Servicer, shall manage, conserve, protect and operate the REO Property in the same manner that it manages, conserves, protects and operates other foreclosed property for its own account, and in the same manner that similar property in the same locality as the REO Property is managed. The Servicer shall furnish to the Trustee and the Credit Risk Manager on or before each Distribution Date a statement with respect to any REO Property covering the operation of such REO Property for the previous calendar month and such other information as the Trustee shall reasonably request and which is necessary to enable the Trustee to comply with the reporting requirements of the REMIC Provisions. The net monthly rental income, if any, from such REO Property shall be deposited in the related Collection Account no later than the close of business on each Determination Date. The Servicer shall perform the tax reporting and withholding required by Sections 1445 and 6050J of the Code with respect to foreclosures and abandonments, the tax reporting required by Section 6050H of the Code with respect to the receipt of mortgage interest from individuals and any tax reporting required by Section 6050P of the Code with respect to the cancellation of indebtedness by certain financial entities, by preparing such tax and information returns as may be required for filing.

To the extent consistent with Accepted Servicing Practices, the Servicer shall also maintain on each REO Property related to a Mortgage Loan fire and hazard insurance with extended coverage in amount which is equal to the outstanding principal balance of the related Mortgage Loan (as reduced by any amount applied as a reduction of principal at the time of acquisition of the REO Property), liability insurance, if any, and, to the extent required and available under the Flood Disaster Protection Act of 1973, as amended, flood insurance in the amount required above.

(c)

In the event that the Trust Fund acquires any Mortgaged Property as aforesaid or otherwise in connection with a default or imminent default on a Mortgage Loan, the Servicer shall dispose of such Mortgaged Property prior to three years after the end of the calendar year of its acquisition by the Trust Fund unless (i) the Trustee shall have been supplied with an Opinion of Counsel to the effect that the holding by the Trust Fund of such Mortgaged Property subsequent to such three-year period will not result in the imposition of taxes on “prohibited transactions” of any REMIC hereunder as defined in Section 860F of the Code or cause any REMIC hereunder to fail to qualify as a REMIC at any time that any Certificates are outstanding, in which case the Trust Fund may continue to hold such Mortgaged Property (subject to any conditions contained in such Opinion of Counsel) or (ii) the Servicer shall have applied for and obtained, prior to the expiration of such three-year period, an extension of such three-year period in the manner contemplated by Section 856(e)(3) of the Code, in which case the three-year period shall be extended by the applicable extension period. Notwithstanding any other provision of this Agreement, no Mortgaged Property acquired by the Trust Fund shall be rented (or allowed to continue to be rented) or otherwise used for the production of income by or on behalf of the Trust Fund in such a manner or pursuant to any terms that would (i) cause such Mortgaged Property to fail to qualify as “foreclosure property” within the meaning of Section 860G(a)(8) of the Code or (ii) subject any REMIC hereunder to the imposition of any federal, state or local income taxes on the income earned from such Mortgaged Property under Section 860G(c) of the Code or otherwise, unless the Servicer has agreed to indemnify and hold harmless the Trust Fund with respect to the imposition of any such taxes.

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

(d)

The decision of the Servicer to foreclose on a defaulted Mortgage Loan shall be subject to a determination by the Servicer that the proceeds of such foreclosure would exceed the costs and expenses of bringing such a proceeding. The income earned from the management of any REO Properties, net of reimbursement to the Servicer for expenses incurred (including any property or other taxes) in connection with such management and net of applicable accrued and unpaid Servicing Fees, and unreimbursed Advances and Servicing Advances, shall be applied to the payment of principal of and interest on the related defaulted Mortgage Loans (with interest accruing as though such Mortgage Loans were still current) and all such income shall be deemed, for all purposes in this Agreement, to be payments on account of principal and interest on the related Mortgage Notes and shall be deposited into the related Collection Account. To the extent the net income received during any calendar month is in excess of the amount attributable to amortizing principal and accrued interest at the related Mortgage Rate on the related Mortgage Loan for such calendar month, such excess shall be considered to be a partial prepayment of principal of such Mortgage Loan.

(e)

The proceeds from any liquidation of a Mortgage Loan, as well as any income from an REO Property, will be applied in the following order of priority: first, to reimburse the Servicer for any related unreimbursed Servicing Advances and Servicing Fees; second, to reimburse the Servicer for any unreimbursed Advances; third, to reimburse the related Collection Account for any Nonrecoverable Advances (or portions thereof) that were previously withdrawn by the Servicer pursuant to Section 3.09(a)(iii) that related to such Mortgage Loan; fourth, to accrued and unpaid interest (to the extent no Advance has been made for such amount or any such Advance has been reimbursed) on the Mortgage Loan or related REO Property, at the per annum rate equal to the related Mortgage Rate reduced by the Servicing Fee Rate to the Due Date occurring in the month in which such amounts are required to be distributed; and fifth, as a recovery of principal of the Mortgage Loan. Excess Proceeds, if any, from the liquidation of a Liquidation Mortgage Loan will be retained by the Servicer as additional servicing compensation pursuant to Section 3.15.

(f)

[Reserved].

(g)

The Servicer, at its option, may (but is not obligated to) purchase from the Trust Fund any Mortgage Loan which is 90 or more days delinquent or which is in foreclosure. If it elects to make any such purchase, the Servicer shall purchase such Mortgage Loan with its own funds at a price equal to the Repurchase Price.

SECTION 3.13

Trustee to Cooperate; Release of Mortgage Files.

Upon the payment in full of any Mortgage Loan, or the receipt by the Servicer of a notification that payment in full will be escrowed in a manner customary for such purposes, the Servicer will immediately notify the Custodian by delivering, or causing to be delivered a “Request for Release” substantially in the form of Exhibit M. Upon receipt of such request, the Custodian shall within four Business Days release the related Mortgage File to the Servicer, and the Trustee shall within four Business Days of the Servicer’s direction execute and deliver to the Servicer the request for reconveyance, deed of reconveyance or release or satisfaction of mortgage or such instrument releasing the lien of the Mortgage in each case provided by the Servicer, together with the Mortgage Note with written evidence of cancellation thereon. The Servicer shall execute lien releases under Power of Attorney from the Trustee. Expenses incurred in connection with any instrument of satisfaction or deed of reconveyance shall be chargeable to the related Mortgagor. From time to time and as shall be appropriate for the servicing or foreclosure of any Mortgage Loan, including for such purpose, collection under any policy of flood insurance, any fidelity bond or errors or omissions policy, or for the purposes of effecting a partial release of any Mortgaged Property from the lien of the Mortgage or the making of any corrections to the Mortgage Note or the Mortgage or any of the other documents included in the Mortgage File, the Trustee shall, within three Business Days of delivery to the Trustee of a Request for Release in the form of Exhibit M signed by a Servicing Officer, release or cause the Custodian to release the Mortgage File to the Servicer. Subject to the further limitations set forth below, the Servicer shall cause the Mortgage File or documents so released to be returned to the Trustee or the Custodian, as applicable, when the need therefor by the Servicer no longer exists, unless the Mortgage Loan is liquidated and the proceeds thereof are deposited in the related Collection Account, in which case the Servicer shall deliver to the Trustee a Request for Release in the form of Exhibit M, signed by a Servicing Officer. The Servicer is also authorized to cause the removal from the registration on the MERS® System of such Mortgage and to execute and deliver, on behalf of the Trustee and the Certificateholders or any of them, any and all instruments of satisfaction or cancellation or of partial or full release, including an assignment of such loan to the Trustee.

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

SECTION 3.14

Documents, Records and Funds in Possession of the Servicer to be Held for the Trustee.

Notwithstanding any other provisions of this Agreement, the Servicer shall transmit to the Custodian on behalf of the Trustee as required by this Agreement all documents and instruments in respect of a Mortgage Loan coming into the possession of the Servicer from time to time required to be delivered to the Trustee pursuant to the terms hereof and shall account fully to the Trustee for any funds received by the Servicer or which otherwise are collected by the Servicer as Liquidation Proceeds or Insurance Proceeds in respect of any Mortgage Loan. All Mortgage Files and funds collected or held by, or under the control of, the Servicer in respect of any Mortgage Loans, whether from the collection of principal and interest payments or from Liquidation Proceeds, including but not limited to, any funds on deposit in a related Collection Account, shall be held by the Servicer for and on behalf of the Trustee and shall be and remain the sole and exclusive property of the Trustee, subject to the applicable provisions of this Agreement. The Servicer also agrees that it shall not create, incur or subject any Mortgage File or any funds that are deposited in the related Collection Account, Certificate Account or any related Escrow Account, or any funds that otherwise are or may become due or payable to the Trustee for the benefit of the Certificateholders, to any claim, lien, security interest, judgment, levy, writ of attachment or other encumbrance, or assert by legal action or otherwise any claim or right of setoff against any Mortgage File or any funds collected on, or in connection with, a Mortgage Loan, except, however, that the Servicer shall be entitled to set off against and deduct from any such funds any amounts that are properly due and payable to the Servicer under this Agreement.

SECTION 3.15

Servicing Compensation.

As compensation for its services hereunder, the Servicer shall be entitled to withdraw from the applicable Collection Account in accordance with Section 3.09(a), payable solely from payments of interest in respect of the related Mortgage Loan, or to retain from interest payments on the related Mortgage Loans the amount of the Servicing Fee for each such Mortgage Loan, less any amounts in respect of its Servicing Fee payable by the Servicer pursuant to Section 3.06(c)(vii).

With respect to any Mortgage Loan, additional servicing compensation in the form of Ancillary Income shall be retained by the Servicer. The Servicer shall be required to pay all expenses incurred by it in connection with its servicing activities hereunder (including the payment of any expenses incurred in connection with any Subservicing Agreement entered into pursuant to Section 3.02 and the payment of any premiums for hazard insurance and any Primary Insurance Policy, and maintenance of the other forms of insurance coverage required by this Agreement) to the extent such amounts do not constitute Advances or Nonrecoverable Advances and shall not be entitled to reimbursement thereof except as specifically provided for in this Agreement.

SECTION 3.16

Access to Certain Documentation.

The Servicer shall provide to the OTS and the FDIC and to comparable regulatory authorities supervising Holders of Subordinate Certificates and the examiners and supervisory agents of the OTS, the FDIC and such other authorities, access to the documentation regarding the Mortgage Loans required by applicable regulations of the OTS and the FDIC. Such access shall be afforded without charge, but only upon reasonable and five Business Days prior written request and during normal business hours at the offices designated by the Servicer. Nothing in this Section shall limit the obligation of the Servicer to observe any applicable law prohibiting disclosure of information regarding the Mortgagors and the failure of the Servicer to provide access as provided in this Section as a result of such obligation shall not constitute a breach of this Section.

SECTION 3.17

Annual Statement as to Compliance.

SECTION 3.18

Annual Independent Public Accountants’ Servicing Statement; Financial Statements.

Not later than the earlier of (a) March 15th of each calendar year (other than the calendar year during which the Closing Date occurs) or (b) with respect to any calendar year during which the Depositor’s annual report on Form 10-K is required to be filed in accordance with the Exchange Act and the rules and regulations of the Commission, 15 calendar days before the date on which the Depositor’s annual report on Form 10-K is required to be filed in accordance with the Exchange Act and the rules and regulations of the Commission (or, in each case, if such day is not a Business Day, the immediately preceding Business Day), the Servicer, at its expense, shall cause a nationally or regionally recognized firm of independent public accountants (who may also render other services to the Servicer, the Seller or any affiliate thereof) which is a member of the American Institute of Certified Public Accountants to furnish a statement to the Depositor and the Trustee to the effect that with respect to the Servicer such firm has examined certain documents and records relating to the servicing of residential mortgage loans which the Servicer is servicing, and that, on the basis of such examination, conducted substantially in compliance with the Uniform Single Attestation Program for Mortgage Bankers or the Audit Guide for HUD Approved Title II Approved Mortgagees and Loan Correspondent Programs, nothing has come to their attention which would indicate that such servicing has not been conducted in compliance with Accepted Servicing Practices, except for (a) such exceptions as such firm shall believe to be immaterial, and (b) such other exceptions as shall be set forth in such statement. In addition, the Servicer shall disclose to such firm all significant deficiencies relating to the Servicer’s compliance with the minimum servicing standards set forth in this Agreement. In rendering such statement, such firm may rely, as to matters relating to direct servicing of mortgage loans by Subservicers, upon comparable statements for examinations conducted substantially in compliance with the Uniform Single Attestation Program for Mortgage Bankers or the Audit Guide for HUD Approved Title II Approved Mortgagees and Loan Correspondent Programs (rendered within one year of such statement) of independent public accountants with respect to the related Subservicer. Copies of such statement shall be provided by the Trustee to any Certificateholder upon request at the Servicer’s expense, provided such statement is delivered by the Servicer to the Trustee. The initial statement required pursuant to this Section 3.18 shall be delivered to the Trustee and the Depositor by the Servicer no later than March 15, 2005.

SECTION 3.19

Maintenance of Fidelity Bond and Errors and Omissions Insurance.

The Servicer shall maintain with responsible companies, at its own expense, a blanket Fidelity Bond and an Errors and Omissions Insurance Policy, with broad coverage on all officers, employees or other persons acting in any capacity requiring such persons to handle funds, money, documents or papers relating to the related Mortgage Loans (“Servicer Employees”). Any such Fidelity Bond and Errors and Omissions Insurance Policy shall be in the form of the Financial Institution Bond Form 24 Fidelity Bond American International Specialty Lines Insurance Policy form (“43350 12/90”) or otherwise in a form acceptable to FNMA or FHMLC, and shall protect and insure the Servicer against losses, including forgery, theft embezzlement, fraud, errors and omissions and negligent acts of the Servicer Employees. Each Fidelity Bond and Errors and Omissions Insurance Policy also shall protect and insure the Servicer against losses in connection with the release or satisfaction of a related Mortgage Loan without having obtained payment in full of the indebtedness secured thereby. No provision of this Section 3.19 requiring such Fidelity Bond and Errors and Omissions Insurance Policy shall diminish or relieve the Servicer from its duties and obligations as set forth in this Agreement. The minimum coverage under any such bond and insurance policy shall be at least equal to the corresponding amounts required by FNMA.

SECTION 3.20

Prepayment Premiums.

With respect to any Mortgage Loan, notwithstanding anything in this Agreement to the contrary, in the event of a Principal Prepayment, the Servicer may not waive any Prepayment Premium or portion thereof required by the terms of the related Mortgage Note unless (i) the related Mortgage Loan is in default or foreseeable default and such waiver (a) is standard and customary in servicing mortgage loans similar to the Mortgage Loans and (b) would, in the reasonable judgment of the Servicer, maximize recovery of total proceeds taking into account the value of such Prepayment Premium and the related Mortgage Loan, (ii) (A) the enforceability thereof is limited (1) by bankruptcy, insolvency, moratorium, receivership, or other similar law relating to creditors’ rights generally or (2) due to acceleration in connection with a foreclosure or other involuntary payment, or (B) the enforceability is otherwise limited or prohibited by applicable law, (iii) the enforceability would be considered “predatory” pursuant to written guidelines issued by any applicable federal, state or local authority having jurisdiction over such matters, or (iv) the Servicer is unable to locate documentation sufficient to allow it to confirm the existence and amount of such Prepayment Premium after using commercially reasonable efforts to locate such documentation, which efforts shall include, but are not limited to, seeking such documentation from the Depositor, the Seller, the Custodian and from its own records or files. For the avoidance of doubt, the Servicer may waive a Prepayment Premium in connection with a short sale or short payoff on a defaulted Mortgage Loan. If the Servicer has waived all or a portion of a Prepayment Premium relating to a Principal Prepayment, other than as provided above, the Servicer shall deliver to the Trustee no later than the next succeeding Servicer Remittance Date, for deposit into the Certificate Account the amount of such Prepayment Premium (or such portion thereof as had been waived) for distribution in accordance with the terms of this Agreement and if the Servicer fails to deliver such amount either the Trustee or the Seller may enforce such obligation. If the Servicer has waived all or a portion of a Prepayment Premium for any reason, it shall notify the Trustee and the Seller thereof and shall include such information in any monthly reports it provides the Trustee and the Seller. Notwithstanding any provision in this Agreement to the contrary, in the event the Prepayment Premium payable under the terms of the related Mortgage Note is less than the amount of the Prepayment Premium set forth in the Mortgage Loan Schedule or other information provided to the Servicer, the Servicer shall not have any liability or obligation with respect to such difference.

SECTION 3.21

Duties and Removal of the Credit Risk Manager.

For and on behalf of the Depositor, the Credit Risk Manager will provide reports and recommendations concerning certain delinquent and defaulted Mortgage Loans, and as to the collection of any Prepayment Premiums with respect to the Mortgage Loans. Such reports and recommendations will be based upon information provided to the Credit Risk Manager pursuant to the Credit Risk Management Agreement, and the Credit Risk Manager shall look solely to the Servicer for all information and data (including loss and delinquency information and data) relating to the servicing of the Mortgage Loans. Upon any termination of the Credit Risk Manager or the appointment of a successor Credit Risk Manager, the Trustee shall give written notice thereof to the Servicer and the Depositor.

If Holders of the Certificates entitled to 66 2/3% or more of the Voting Rights request in writing to the Trustee to terminate the Credit Risk Manager under this Agreement, the Credit Risk Manager shall be removed pursuant to this Section. Upon receipt of such notice, the Trustee shall provide written notice to the Credit Risk Manager of its removal, which shall be effective upon receipt of such notice by the Credit Risk Manager.

SECTION 3.22

Advance Facility.

(a)

The Servicer is hereby authorized to enter into a financing or other facility (any such arrangement, an “Advance Facility”) under which (1) the Servicer assigns or pledges to another Person (an “Advancing Person”) the Servicer’s rights under this Agreement to be reimbursed for any Advances or Servicing Advances and/or (2) an Advancing Person agrees to fund some or all Advances and/or Servicing Advances required to be made by the Servicer pursuant to this Agreement. No consent of the Trustee, Certificateholders or any other party is required before the Servicer may enter into an Advance Facility; provided, however, that the consent of the Trustee shall be required before the Servicer may cause to be outstanding at one time more than one Advance Facility with respect to Advances or more than one Advance Facility with respect to Servicing Advances. Notwithstanding the existence of any Advance Facility under which an Advancing Person agrees to fund Advances and/or Servicing Advances on the Servicer’s behalf, the Servicer shall remain obligated pursuant to this Agreement to make Advances and Servicing Advances pursuant to and as required by this Agreement, and shall not be relieved of such obligations by virtue of such Advance Facility. If the Servicer enters into an Advance Facility, and for so long as an Advancing Person remains entitled to receive reimbursement for any Advances or Servicing Advances outstanding and previously unreimbursed pursuant to this Agreement, then the Servicer shall identify amounts collected that would otherwise be retained by the Servicer to reimburse it for previously unreimbursed Advances (“Advance Reimbursement Amounts”) and/or previously unreimbursed Servicing Advances (“Servicing Advance Reimbursement Amounts” and together with Advance Reimbursement Amounts, “Reimbursement Amounts”) (in each case to the extent such type of Reimbursement Amount is included in the Advance Facility) as such amounts are received, consistently with the reimbursement rights set forth in this Agreement, and shall remit such Reimbursement Amounts in accordance with the documentation establishing the Advance Facility to such Advancing Person or to a trustee, agent or custodian (an “Advance Facility Trustee”) designated by such Advancing Person. Notwithstanding the foregoing, if so required pursuant to the terms of the Advance Facility, the Servicer may direct the Trustee to, and if so directed the Trustee is hereby authorized to and shall, pay to the Advancing Person or the Advance Facility Trustee the Reimbursement Amounts identified pursuant to the preceding sentence. Notwithstanding anything to the contrary herein, in no event shall Advance Reimbursement Amounts or Servicing Advance Reimbursement Amounts be included in Interest Remittance Amounts or Principal Remittance Amounts or distributed to Certificateholders. If the Servicer making an election to remit Reimbursement Amounts to the Trustee it shall report to the Trustee the portions of the Reimbursement Amounts that consist of Advance Reimbursement Amounts and Servicing Advance Reimbursement Amounts, respectively.

(b)

If the Servicer enters into an Advance Facility and makes the election to remit Reimbursement Amounts to the Trustee as described in Section 3.22(a), the Servicer and the related Advancing Person shall deliver to the Trustee a written notice and payment instruction (an “Advance Facility Notice”), providing the Trustee with written payment instructions as to where to remit Advance Reimbursement Amounts and/or Servicing Advance Reimbursement Amounts (each to the extent such type of Reimbursement Amount is included within the Advance Facility) on subsequent Distribution Dates. The payment instruction shall require the applicable Reimbursement Amounts to be distributed to the Advancing Person or to an Advance Facility Trustee designated in the Advance Facility Notice. An Advance Facility Notice may only be terminated by the joint written direction of the Servicer and the related Advancing Person (and any related Advance Facility Trustee); provided, however, that the provisions of this Section 3.22 shall cease to be applicable when all Advances and Servicing Advances funded by an Advancing Person, and when all Advances and Servicing Advances (the rights to be reimbursed for which have been assigned or pledged to an Advancing Person), have been repaid to the related Advancing Person in full.

(c)

Reimbursement Amounts shall consist solely of amounts in respect of Advances and/or Servicing Advances made with respect to the Mortgage Loans for which the Servicer would be permitted to reimburse itself in accordance with Sections 3.07(d)(ii) and 3.09(a)(ii), (iii) and (iv) hereof, assuming the Servicer had made the related Advance(s) and/or Servicing Advance(s). Notwithstanding the foregoing, no Person shall be entitled to reimbursement from funds held in the Collection Account for future distribution to Certificateholders pursuant to the provisions of Section 4.01. The Trustee shall not have any duty or liability with respect to the calculation of any Reimbursement Amount and, if the Servicer has elected to remit Reimbursement Amounts to the Trustee, shall be entitled to rely without independent investigation on the Advance Facility Notice and on the Servicer’s report of the amount of Advance Reimbursement Amounts and Servicing Advance Reimbursement Amounts that were included in the remittance from the Servicer to the Trustee pursuant to Section 3.09(a)(viii) or (ix). The Servicer shall maintain and provide to any successor Servicer a detailed accounting on a loan-by-loan basis as to amounts advanced by, pledged or assigned to, and reimbursed to any Advancing Person. The successor Servicer shall be entitled to rely on any such information provided by the predecessor Servicer, and the successor Servicer shall not be liable for any errors in such information.

(d)

An Advancing Person who receives an assignment or pledge of the rights to be reimbursed for Advances and/or Servicing Advances, and/or whose obligations hereunder are limited to the funding of Advances and/or Servicing Advances shall not be required to meet the criteria for qualification of a Sub-Servicer set forth in Section 3.02 hereof.

(e)

Reimbursement Amounts distributed with respect to each Mortgage Loan shall be allocated to outstanding unreimbursed Advances or Servicing Advances (as the case may be) made with respect to that Mortgage Loan on a “first-in, first-out” (FIFO) basis. The Servicer entering into an Advance Facility shall provide to the related Advancing Person or Advance Facility Trustee loan-by-loan information with respect to each Reimbursement Amount remitted to such Advancing Person or Advance Facility Trustee on each Distribution Date or otherwise, to enable the Advancing Person or Advance Facility Trustee to make the FIFO allocation of each Reimbursement Amount with respect to each Mortgage Loan. The Servicer shall remain entitled to be reimbursed by the Advancing Person or Advance Facility Trustee for all Advances and Servicing Advances funded by the Servicer to the extent the related rights to be reimbursed therefor have not been assigned or pledged to an Advancing Person.

(f)

The Servicer who enters into an Advance Facility shall indemnify the Trustee, the Trust and any successor Servicer, as applicable, from and against any claims, losses, liabilities or damages resulting from any claim by the related Advancing Person, except to the extent that such claim, loss, liability or damage resulted from or arose out of negligence, recklessness or willful misconduct on the part of the Trustee or the successor Servicer, or failure by the successor Servicer or the Trustee to remit funds as required by this Agreement or the commission of an act or omission to act by the successor Servicer or the Trustee, and the passage of any applicable cure or grace period, such that an Event of Default under this Agreement occurs or such entity is subject to termination for cause under this Agreement.

DISTRIBUTIONS AND ADVANCES

SECTION 4.01

Advances.

With respect to any Mortgage Loan, the Servicer shall deposit in the related Collection Account at the time described below an amount equal to with respect to the Mortgage Loans, all Scheduled Payments (with interest at the Mortgage Rate less the Servicing Fee Rate) which were due on the Mortgage Loans during the applicable Collection Period; provided however, that with respect to any Balloon Loan that is delinquent on its maturity date, the Servicer will not be required to advance the related balloon payment but will be required to continue to make advances in accordance with this Section 4.01 with respect to such Balloon Loan in an amount equal to an assumed scheduled payment that would otherwise be due based on the original amortization schedule for that Mortgage Loan (with interest at the Mortgage Rate less the Servicing Fee Rate). The Servicer’s obligation to make such Advances as to any Mortgage Loan will continue through the last Scheduled Payment due prior to the payment in full of such Mortgage Loan, or the related Mortgaged Property or related REO Property has been liquidated or until the purchase or repurchase thereof (or substitution therefor) from the Trust Fund pursuant to the terms of this Agreement. The Servicer shall not be required to advance shortfalls of principal or interest resulting from the application of the Relief Act.

The Servicer shall be obligated to make Advances with respect to the Mortgage Loans in accordance with the provisions of this Agreement; provided however, that such obligation shall cease if the Servicer determines, in its sole discretion, that Advances with respect to such Mortgage Loan are Nonrecoverable Advances. In the event that the Servicer determines that any such Advances are Nonrecoverable Advances, the Servicer shall provide the Trustee with a certificate signed by a Servicing Officer evidencing such determination.

With respect to any Mortgage Loan, if an Advance is required to be made hereunder, the Servicer shall on the applicable Servicer Remittance Date immediately following the Determination Date either (i) deposit in the related Collection Account from its own funds an amount equal to such Advance, (ii) cause to be made an appropriate entry in the records of such Collection Account that funds in such account being held for future distribution or withdrawal have been, as permitted by this Section 4.01, used by the Servicer to make such Advance or (iii) make Advances in the form of any combination of clauses (i) and (ii) aggregating the amount of such Advance. Any such funds being held in a Collection Account for future distribution and so used shall be replaced by the Servicer from its own funds by deposit in such Collection Account on or before the next Distribution Date in which such funds would be due.

Any distributions of Monthly Excess Cashflow to the holders of the Offered Certificates pursuant to Sections 4.02(d)(xi)(A)-(J) shall be deemed to have been deposited in the Basis Risk Reserve Fund and paid to such holders. On any Distribution Date, any amounts on deposit in the Basis Risk Reserve Fund in excess of the Required Basis Risk Reserve Fund Amount shall be distributed to the Class X Certificateholder pursuant to Section 4.02(d)(xii).

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 which must be in excess of the applicable minimum denomination) and aggregate denominations per Class set forth in the Preliminary Statement.

Subject to Section 9.02 respecting the final distribution on the Certificates, on each Distribution Date the Trustee 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 (i) such Holder has so notified the Trustee at least five Business Days prior to the related Record Date and (ii) such Holder shall hold (A) a Notional Amount Certificate, (B) 100% of the Class Principal Balance of any Class of Certificates or (C) Certificates of any Class with aggregate principal Denominations of not less than $1,000,000 or (y) by check mailed by first class mail to such Certificateholder at the address of such holder appearing in the Certificate Register.

The Certificates shall be executed by manual or facsimile signature on behalf of the Trustee by a Responsible Officer upon the written order of the Depositor. 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 Trustee shall bind the Trustee, 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 there appears on such certificate a Certificate of Authentication in the form provided herein, executed by the Trustee 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 countersignature. On the Closing Date, the Trustee shall authenticate the Certificates to be issued at the written direction of the Depositor, or any affiliate thereof.

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

SECTION 5.02

Certificate Register; Registration of Transfer and Exchange of Certificates.

(a)

The Trustee 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 Trustee 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 Trustee 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 Trustee. Whenever any Certificates are so surrendered for exchange, the Trustee 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 Trustee 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 disposed of by the Trustee in accordance with the Trustee’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. Except in connection with any transfer of a Private Certificate by the Depositor to any affiliate, in the event that a transfer is to be made in reliance upon an exemption from the Securities Act and such laws, in order to assure compliance with the Securities Act and such laws, the Certificateholder desiring to effect such transfer shall certify to the Trustee in writing the facts surrounding the transfer in substantially the form set forth in Exhibit J (the “Transferor Certificate”) and such Certificateholder’s prospective transferee shall either (i) deliver a letter in substantially the form of (A) Exhibit L (the “Rule 144A Letter”) or (B) if the Private Certificate subject to such transfer represents the entire Class or the Depositor otherwise consents to such transfer, Exhibit K (the “Investment Letter”) or (ii) there shall be delivered to the Trustee at the expense of the transferor an Opinion of Counsel that such transfer may be made pursuant to an exemption from the Securities Act. The Depositor shall provide to any Holder of a Private Certificate and any prospective transferee designated by any such Holder, information regarding the related Certificates and the Mortgage Loans and such other information as shall be necessary to satisfy the condition to eligibility set forth in Rule 144A(d)(4) for transfer of any such Private Certificate without registration thereof under the Securities Act pursuant to the registration exemption provided by Rule 144A. The Trustee shall cooperate with the Depositor in providing the Rule 144A information referenced in the preceding sentence, including providing to the Depositor such information regarding the Certificates, the Mortgage Loans and other matters regarding the Trust Fund as the Depositor shall reasonably request to meet its obligation under the preceding sentence. Each Holder of a Private Certificate desiring to effect such transfer shall, and does hereby agree to, indemnify the Trustee, the Depositor, the Seller and the Servicer against any liability that may result if the transfer is not so exempt or is not made in accordance with such federal and state laws.

No transfer of an ERISA-Restricted Certificate shall be made unless the Trustee shall have received in accordance with Exhibit I, Exhibit K or Exhibit L, as applicable, either (i) a representation letter from the transferee of such Certificate, acceptable to and in form and substance satisfactory to the Trustee, to the effect that such transferee is not a Plan or a Person acquiring such ERISA-Restricted Certificate for, on behalf of or with the assets of, any such Plan, (a “Benefit Plan Investor”), which representation letter shall not be an expense of the Trustee or the Trust Fund, (ii) in the case of an ERISA-Restricted Certificate if the purchaser is an insurance company and the Certificate has been the subject of an ERISA-Qualifying Underwriting, a representation that the purchaser is an insurance company which is purchasing such Certificates with funds contained in an “insurance company general account” (as such term is defined in Section V(e) of Prohibited Transaction Class Exemption 95-60 (“PTCE 95-60”)) and that the purchase and holding of such Certificates are covered under Sections I and III of PTCE 95-60 or (iii) in the case of any ERISA-Restricted Certificate presented for registration in the name of a Benefit Plan Investor without a representation as required above, an Opinion of Counsel satisfactory to the Trustee to the effect that the purchase or holding of such Certificate will not result in prohibited transactions under Section 406 of ERISA and/or Section 4975 of the Code and will not subject the Depositor, the Trustee or the Servicer to any obligation in addition to those undertaken in this Agreement, which Opinion of Counsel shall not be an expense of such parties. In the event the representations referred to in the preceding sentence are not furnished, such representations shall be deemed to have been made to the trustee by the transferee’s acceptance of an ERISA-Restricted Certificate by any beneficial owner who purchases an interest in such Certificate in book-entry form. In the event that a representation is violated, or any attempt to transfer an ERISA-Restricted Certificate to a Benefit Plan Investor is attempted without the delivery to the Trustee of the Opinion of Counsel described above, the attempted transfer or acquisition of such Certificate shall be void and of no effect.

To the extent permitted under applicable law (including, but not limited to, ERISA), the Trustee shall be under no liability to any Person for any registration of transfer of any ERISA-Restricted Certificate that is in fact not permitted by this Section 5.02(b) or for making any payments due on such Certificate to the Holder thereof or taking any other action with respect to such Holder under the provisions of this Agreement so long as the transfer was registered by the Trustee 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 Trustee 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 Trustee shall not register the Transfer of any Residual Certificate unless, in addition to the certificates required to be delivered to the Trustee under subparagraph (b) above, the Trustee shall have been furnished with an affidavit (a “Transfer Affidavit”) of the initial owner or the proposed transferee in the form attached hereto as Exhibit I.

(iii)

Each Person holding or acquiring any Ownership Interest in a Residual Certificate shall agree (A) to obtain a Transfer Affidavit from any other Person to whom such Person attempts to Transfer its Ownership Interest in a Residual Certificate, (B) to obtain a Transfer Affidavit from any Person for whom such Person is acting as nominee, trustee or agent in connection with any Transfer of a Residual Certificate and (C) not to Transfer its Ownership Interest in a Residual Certificate or to cause the Transfer of an Ownership Interest in a Residual Certificate to any other Person if it has actual knowledge that such Person is not a Permitted Transferee.

(iv)

Any attempted or purported Transfer of any Ownership Interest in a Residual Certificate in violation of the provisions of this Section 5.02(c) shall be absolutely null and void and shall vest no rights in the purported Transferee. If any purported transferee shall become a Holder of a Residual Certificate in violation of the provisions of this Section 5.02(c), then the last preceding Permitted Transferee shall be restored to all rights as Holder thereof retroactive to the date of registration of Transfer of such Residual Certificate. The Trustee shall be under no liability to any Person for any registration of a Transfer of a Residual Certificate that is in fact not permitted by Section 5.02(b) and this Section 5.02(c) or for making any payments due on such Certificate to the Holder thereof or taking any other action with respect to such Holder under the provisions of this Agreement so long as the Transfer was registered after receipt of the related Transfer Affidavit, Transferor Certificate and either the Rule 144A Letter or the Investment Letter. The Trustee shall be entitled but not obligated to recover from any Holder of a Residual Certificate that was in fact not a Permitted Transferee at the time it became a Holder or, at such subsequent time as it became other than a Permitted Transferee, all payments made on such Residual Certificate at and after either such time. Any such payments so recovered by the Trustee shall be paid and delivered by the Trustee to the last preceding Permitted Transferee of such Certificate.

(v)

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

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

(d)

The preparation and delivery of all certificates and opinions referred to above in this Section 5.02 in connection with transfer shall be at the expense of the parties to such transfers.

(e)

Except as provided below, the Book-Entry Certificates shall at all times remain registered in the name of the Depository or its nominee and at all times: (i) registration of the Certificates may not be transferred by the Trustee 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 Trustee 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 Trustee 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 Trustee in writing that the Depository is no longer willing or able to properly discharge its responsibilities as Depository, and (ii) the Trustee or the Depositor is unable to locate a qualified successor, (y) the Depositor, with the consent of the applicable Depository Participants, advises the Trustee in writing that it elects to terminate the book-entry system through the Depository or (z) after the occurrence of an Event of Default, Certificate Owners representing at least 51% of the Certificate Balance of the Book-Entry Certificates together advise the Trustee and the Depository through the Depository Participants in writing that the continuation of a book-entry system through the Depository is no longer in the best interests of the Certificate Owners and the Depository Participants consent to the termination, the Trustee 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 Trustee of the related Class of Certificates by the Depository, accompanied by the instructions from the Depository for registration, the Trustee shall issue the Definitive Certificates. None of the Seller, the Servicer, the Depositor or the Trustee 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 Trustee 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 Trustee, to the extent applicable with respect to such Definitive Certificates and the Trustee shall recognize the Holders of the Definitive Certificates as Certificateholders hereunder; provided that the Trustee shall not by virtue of its assumption of such obligations become liable to any party for any act or failure to act of the Depository.

SECTION 5.03

Mutilated, Destroyed, Lost or Stolen Certificates.

If (a) any mutilated Certificate is surrendered to the Trustee, or the Trustee receives evidence to its satisfaction of the destruction, loss or theft of any Certificate and (b) there is delivered to the Trustee such security or indemnity as may be required by it to hold it harmless, then, in the absence of notice to the Trustee that such Certificate has been acquired by a bona fide purchaser, the Trustee 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 Trustee 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 Trustee) 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 Servicer and the Trustee and any agent of the Servicer or the Trustee may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions as provided in this Agreement and for all other purposes whatsoever, and none of the Servicer or the Trustee or any agent of the Servicer or the Trustee shall be affected by any notice to the contrary.

SECTION 5.05

Access to List of Certificateholders’ Names and Addresses.

If three or more Certificateholders (a) request such information in writing from the Trustee, (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 the Servicer shall request such information in writing from the Trustee, then the Trustee shall, within ten Business Days after the receipt of such request, provide the Depositor, the Servicer or such Certificateholders at such recipients’ expense the most recent list of the Certificateholders of such Trust Fund held by the Trustee, if any. The Depositor and every Certificateholder, by receiving and holding a Certificate, agree that the Trustee 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 Trustee will maintain or cause to be maintained at its expense an office or offices or agency or agencies in St. Paul, Minnesota where Certificates may be surrendered for registration of transfer or exchange. The Trustee initially designates its Corporate Trust Office for such purposes. The Trustee will give prompt written notice to the Certificateholders of any change in such location of any such office or agency.

SECTION 6.01

The Depositor, the Seller and the Servicer shall each be liable in accordance herewith only to the extent of the obligations specifically and respectively imposed upon and undertaken by them herein.

SECTION 6.02

Merger or Consolidation of the Depositor, the Seller or the Servicer.

The Depositor, the Seller and the Servicer will each keep in full effect its existence, rights and franchises as a corporation under the laws of the United States or under the laws of one of the states thereof and will each obtain and preserve its qualification to do business as a foreign corporation in each jurisdiction in which such qualification is or shall be necessary to protect the validity and enforceability of this Agreement, or any of the Mortgage Loans and to perform its respective duties under this Agreement.

Notwithstanding the provision of Section 6.04 herein to the contrary, in the event that the Servicer determines that it will no longer engage in the business of servicing mortgage loans, the Servicer, may assign its rights under this Agreement, provided that (i) the Depositor in its sole discretion has consented, (ii) the Rating Agencies’ ratings of the Offered Certificates in effect immediately prior to such action will not be qualified, reduced or withdrawn as a result thereof (as evidenced by a letter to such effect from the Rating Agencies) and (iii) the Servicer shall be liable for all costs and expenses (including attorney’s fees) incurred in connection with the assignment and related transfer of servicing of the Mortgage Loans, provided further, that the Servicer shall indemnify and hold the Trust, the Trustee, the Depositor, any Subservicer, the successor Servicer and each Certificateholder harmless against any and all claims, losses, penalties, fines, forfeitures, reasonable legal fees and related costs, judgments and any other costs, fees and expenses that the Trust, the Trustee, the Depositor, any Subservicer, the successor Servicer and each Certificateholder may sustain in any way related to such assignment. No assignment by the Servicer shall become effective until a successor Servicer acceptable to the Depositor and the Trustee shall have assumed the Servicer’s responsibilities, duties, liabilities (other than those liabilities arising prior to the appointment of such successor) and obligations under this Agreement. Any such assignment shall not relieve the Servicer of responsibility for any of the obligations specified herein except to the extent that such responsibilities have been expressly assumed by such successor Servicer.

SECTION 6.03

Limitation on Liability of the Depositor, the Seller and the Servicer.

(a)

None of the Depositor, the Seller or the Servicer nor any of the directors, officers, employees or agents of the Depositor, the Seller or the Servicer shall be under any liability to the Certificateholders for any action taken or for refraining from the taking of any action in good faith pursuant to this Agreement, or for errors in judgment; provided, however, that this provision shall not protect the Depositor, the Seller, the Servicer or any such Person against any breach of representations or warranties made by it herein or protect Depositor, the Seller, the Servicer or any such Person from any liability which would otherwise be imposed by reasons of willful misfeasance, bad faith or gross negligence in the performance of duties or by reason of reckless disregard of obligations and duties hereunder.

The Depositor, the Seller and the Servicer and any director, officer, employee or agent of the Depositor, the Seller or the Servicer may rely in good faith on any document of any kind prima facie properly executed and submitted by any Person respecting any matters arising hereunder.

None of the Depositor, the Seller or the Servicer shall be under any obligation to appear in, prosecute or defend any legal action that is not incidental to its respective duties hereunder and which in its opinion may involve it in any expense or liability; provided, however, that any of the Depositor, the Seller or the Servicer may in its discretion undertake any such action that it may deem necessary or desirable in respect of this Agreement and the rights and duties of the parties hereto and interests of the Trustee and the Certificateholders hereunder. In such event, the legal expenses and costs of such action and any liability resulting therefrom shall be expenses, costs and liabilities of the Trust Fund, and the Depositor, the Seller and the Servicer shall be entitled to be reimbursed therefor from the Trust Fund. The Servicer’s right to indemnity and reimbursement pursuant to this Section 6.03 shall survive the resignation or termination of the Servicer as set forth herein.

(b)

The Servicer shall indemnify the Trustee and hold it harmless against any and all claims, losses, damages, penalties, fines, forfeitures, reasonable and necessary legal fees and related costs, judgments, and any other costs, fees and expenses that the Trustee may sustain in any way related to the failure of the Servicer to perform its duties and service the Mortgage Loans in compliance with the terms of this Agreement. The Servicer immediately shall notify the Trustee if a claim is made by a third party with respect to this Agreement or the Mortgage Loans, assume (with the prior written consent of the Trustee) the defense of any such claim and pay all expenses in connection therewith, including counsel fees, and promptly pay, discharge and satisfy any judgment or decree which may be entered against it or the Trustee in respect of such claim. The Servicer shall follow any written instructions received from the Trustee in connection with such claim. Except as otherwise provided herein, the Trustee promptly shall reimburse the Servicer for all amounts advanced by such entity pursuant to the second preceding sentence except when the claim is in any way related to the failure of the Servicer to service and administer the Mortgage Loans in compliance with the terms of this Agreement.

SECTION 6.04

Limitation on Resignation of the Servicer.

(a)

Subject to Sections 6.04(b) below, the Servicer shall not resign from the obligations and duties hereby imposed on it except (i)(a) upon appointment of a successor servicer and (b) receipt by the Trustee of a letter from each Rating Agency that such a resignation and appointment will not result in a downgrading of the rating of any of the Certificates related to the applicable Mortgage Loans, or (ii) upon determination that its duties hereunder are no longer permissible under applicable law. Any such determination under clause (ii) permitting the resignation of the Servicer shall be evidenced by an Opinion of Counsel to such effect delivered to the Trustee. No such resignation shall become effective until the Trustee or a successor servicer shall have assumed the Servicer’s responsibilities, duties, liabilities and obligations hereunder.

(b)

Notwithstanding the foregoing, at DLJMC’s request, so long as it is the owner of the related servicing rights, the Servicer shall resign upon the selection and appointment of a successor servicer; provided that the Seller delivers to the Trustee the letter required by 6.04(a)(i) above. To the extent that the compensation of any such successor servicer exceeds the Servicing Fee Rate of the Servicer that has resigned, in accordance with Section 7.02, each Holder of a Class A-IO-S Certificate hereby agrees to a decrease in the Excess Servicing Fee in an amount equal to the excess of the Servicing Fee for the successor to theServicer over the Servicing Fee due to the Servicer that has resigned.

SECTION 6.05

Limitation Upon Liability of the Credit Risk Manager.

Neither the Credit Risk Manager, nor any of its directors, officers, employees, or agents shall be under any liability hereunder to the Trustee, the Certificateholders, or the Depositor for any action taken or for refraining from the taking of any action made in good faith pursuant to this Agreement or the Credit Risk Management Agreement, in reliance upon information provided by the Servicer under the Credit Risk Management Agreement, or for errors in judgment; provided, however, that this provision shall not protect the Credit Risk Manager or any such person against liability that would otherwise be imposed by reason of willful malfeasance, gross negligence or bad faith in its performance of its duties or by reason of reckless disregard for its obligations and duties under this Agreement or the applicable Credit Risk Management Agreement. The Credit Risk Manager and any director, officer, employee, or agent of the Credit Risk Manager may rely in good faith on any document of any kind prima facie properly executed and submitted by any Person respecting any matters arising hereunder, and may rely in good faith upon the accuracy of information furnished by the Servicer pursuant to the applicable Credit Risk Management Agreement in the performance of its duties thereunder and hereunder.

The Trustee or other successor entity, as applicable, is hereby authorized and empowered to execute and deliver, on behalf of the Servicer, as attorney-in-fact or otherwise, any and all documents and other instruments, and to do or accomplish all other acts or things necessary or appropriate to effect the purposes of such notice of termination, whether to complete the transfer and endorsement or assignment of the related Mortgage Loans and related documents, or otherwise.

All reasonable out of pocket costs and expenses (including attorney’s fees) incurred in connection with transferring servicing to a successor Servicer shall be paid by the predecessor Servicer (or if the predecessor Servicer is the Trustee, the initial Servicer) upon presentation of reasonable documentation of such costs and expenses.

The Servicer shall continue to be entitled to the benefits of Section 6.03 hereof, notwithstanding any termination hereunder, with respect to any events occurring prior to such termination.

In no event shall the termination of the Servicer under this Agreement result in any diminution of the Servicer’s right to reimbursement for any outstanding Advances or Servicing Advances or accrued and unpaid Servicing Fees due the Servicer at the time of termination. The successor Servicer shall reimburse the terminated Servicer for outstanding Advances and Servicing Advances and accrued and unpaid Servicing Fees to the extent that such amounts become reimbursable from time to time pursuant to Section 3.09 of this Agreement; provided, however, that such right of reimbursement shall be limited to funds that are on deposit in the Collection Account and available to the Servicer for such purposes pursuant to Section 3.09 of this Agreement. In addition, any such reimbursement for outstanding Advances and Servicing Advances and accrued and unpaid Servicing Fees shall be made on a first in, first out (“FIFO”) basis no later than the Servicer Remittance Date of each month.

SECTION 7.02

Trustee to Act; Appointment of Successor.

On and after the time the Servicer receives a notice of termination pursuant to Section 7.01 of this Agreement, the Trustee or a successor servicer appointed pursuant to Section 7.01, subject to and to the extent provided herein, either shall be the successor to the Servicer, but only in its capacity as servicer under this Agreement and not in any other, and the transactions set forth herein or shall appoint a successor servicer, and in either event such successor servicer shall be subject to all the responsibilities, duties and liabilities relating thereto placed on the Servicer by the terms and provisions hereof and applicable law including the obligation to make Advances pursuant to Section 4.01. As compensation therefor, the successor servicer shall be entitled to all funds relating to the related Mortgage Loans that the terminated Servicer would have been entitled to charge to a Collection Account, provided that the terminated Servicer shall nonetheless be entitled to payment or reimbursement as provided in Section 3.09(a) to the extent that such payment or reimbursement relates to the period prior to the completion of the transfer of servicing to a successor servicer. Notwithstanding the foregoing, if the Trustee has become the successor to the terminated Servicer in accordance with Section 7.01, the Trustee may, if it shall be unwilling to so act, or shall, if it is prohibited by applicable law from making Advances pursuant to 4.01 hereof, or if it is otherwise unable to so act, 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 terminated Servicer hereunder in the assumption of all or any part of the responsibilities, duties or liabilities of the Servicer hereunder. Any successor to the Servicer shall be an institution which is a FNMA or FHLMC approved seller/servicer in good standing, which has a net worth of at least $10,000,000, which is willing to service the related Mortgage Loans and which executes and delivers to the Depositor and the Trustee an agreement accepting such delegation and assignment, containing an assumption by such Person of the rights, powers, duties, responsibilities, obligations and liabilities of the Servicer (other than liabilities of the Servicer under Section 6.03 hereof incurred prior to termination of the Servicer under Section 7.01 hereunder), with like effect as if originally named as a party to this 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 the Servicer hereunder, the Trustee or other successor servicer unless such entity is prohibited by law from so acting, shall, subject to the limitations described herein, act in such capacity as hereinabove provided. In connection with such appointment and assumption, the Trustee may make such arrangements for the compensation of such successor out of payments on the related Mortgage Loans as it and such successor shall agree; provided, however, that no such compensation shall be in excess of the Servicing Fee, assuming for this purpose that the Servicing Fee Rate is 0.50% per annum, for any other successor. To the extent that the compensation of any successor to the Servicer is calculated using a rate exceeding the then-current rate used to calculate the Ocwen Servicing Fee Rate (as defined in the Ocwen Side Letter), as the case may be, each Holder of a Class A-IO-S Certificate hereby agrees to a decrease in the Excess Servicing Fee Rate in an amount equal to such excess. The Trustee and such successor shall take such action, consistent with this Agreement, as shall be necessary to effectuate any such succession. Neither the Trustee nor any other successor servicer shall be deemed to be in default by reason of any failure to make, or any delay in making, any distribution hereunder or any portion thereof or any failure to perform, or any delay in performing, any duties or responsibilities hereunder, in either case caused by the failure of the terminated Servicer to deliver or provide, or any delay in delivering or providing, any cash, information, documents or records to it.

Any successor to the Servicer or shall give notice to the Mortgagors of such change of servicer. Any successor to the Servicer shall, during the term of its service as the Servicer maintain in force the policy or policies of the type that the Servicer is required to maintain pursuant to this Agreement.

In connection with the termination or resignation of the Servicer hereunder, either (i) the successor Servicer, including the Trustee if the Trustee is acting as successor Servicer, shall represent and warrant that it is a member of MERS in good standing and shall agree to comply in all material respects with the rules and procedures of MERS in connection with the servicing of the Mortgage Loans that are registered with MERS, or (ii) the predecessor Servicer, at its sole expense, shall cooperate with the successor Servicer either (x) in causing MERS to execute and deliver an Assignment of Mortgage in recordable form to transfer the Mortgage from MERS to the Trustee and to execute and deliver such other notices, documents and other instruments as may be necessary or desirable to effect a transfer of such Mortgage Loan or servicing of such Mortgage Loan on the MERS® System to the successor Servicer or (y) in causing MERS to designate on the MERS® System the successor Servicer as the servicer of such Mortgage Loan (at the cost and expense of the successor Servicer to the extent such costs relate to the qualification of such successor Servicer as a member of MERS, otherwise at the cost and expense of the predecessor Servicer). The predecessor Servicer shall file or cause to be filed any such assignment in the appropriate recording office. The successor Servicer shall cause such assignment to be delivered to the Trustee promptly upon receipt of the original with evidence of recording thereon or a copy certified by the public recording office in which such assignment was recorded.

SECTION 7.03

Notification to Certificateholders.

(a)

Upon any termination of or appointment of a successor to the Servicer, the Trustee shall give prompt written notice thereof to Certificateholders and to each Rating Agency.

(b)

Within 60 days after the occurrence of any Event of Default, the Trustee shall transmit by mail to all Certificateholders notice of each such Event of Default hereunder actually known to a Responsible Officer the Trustee, unless such Event of Default shall have been cured or waived.

The Trustee makes no representations as to the validity or sufficiency of this Agreement or of the Certificates or of any Mortgage Loan or related document or of MERS or the MERS® System, other than with respect to the Trustee’s execution and authentication of the Certificates. The Trustee shall not be accountable for the use or application by the Depositor or the Servicer of any funds paid to the Depositor or the Servicer in respect of the Mortgage Loans or deposited in or withdrawn from the Collection Account by the Depositor or the Servicer.

SECTION 8.04

Trustee May Own Certificates.

The Trustee in its individual or any other capacity may become the owner or pledgee of Certificates and may transact business with the Depositor, the Seller, the Servicer and their affiliates, with the same rights as it would have if it were not the Trustee.

SECTION 8.05

Trustee’s Fees and Expenses.

(a)

In addition to the Trustee Fee, the Trustee, as compensation for its activities hereunder, shall be entitled to withdraw from the Certificate Account on each Distribution Date prior to making distributions pursuant to Section 4.02 any investment income or other benefit derived from balances in the Certificate Account for such Distribution Date pursuant to Section 3.09(b). Subject to the limitations set forth in Section 8.05(b), the Trustee and any director, officer, employee or agent of the Trustee shall be indemnified by the Depositor and held harmless against any loss, liability or expense (including reasonable attorney’s fees and expenses) incurred in connection with any claim or legal action relating to (a) this Agreement or the Custodial Agreement, (b) the Certificates, or (c) the performance of any of the Trustee’s duties hereunder or under the Custodial Agreement, other than any loss, liability or expense (i) incurred by reason of willful misfeasance, bad faith or negligence in the performance of any of the Trustee’s duties hereunder or incurred by reason of any action of the Trustee taken at the direction of the Certificateholders or (ii) that does not constitute an “unanticipated expense” of any REMIC formed hereby within the meaning of Treasury Regulation Section 1.860G—1(b)(3)(ii). Such indemnity shall survive the termination of this Agreement or the resignation or removal of the Trustee hereunder. Without limiting the foregoing, the Depositor covenants and agrees, subject to the limitation set forth in Section 8.05(b), and except for any such expense, disbursement or advance as may arise from the Trustee’s negligence, bad faith or willful misconduct, to pay or reimburse the Trustee, for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any of the provisions of this Agreement with respect to: (A) the reasonable compensation and the expenses and disbursements of its counsel not associated with the closing of the issuance of the Certificates, (B) the reasonable compensation, expenses and disbursements of any accountant, engineer or appraiser that is not regularly employed by the Trustee, to the extent that the Trustee must engage such persons to perform acts or services hereunder, (C) printing and engraving expenses in connection with preparing any Definitive Certificates and (D) any other reasonable expenses incurred other than in the ordinary course of its business by the Trustee in connection with its duties hereunder.

(b)

Notwithstanding anything to the contrary in this Agreement, the Depositor shall not be obligated to pay to the Trustee more than, in the aggregate, $150,000 pursuant to Section 8.05(a) hereof. Other than as set forth in this Section 8.05, the Trustee shall not be entitled to any other compensation or reimbursement for loss or expenses.

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 either 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 proposes 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 the provisions of 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, the Seller or the Servicer and their affiliates; provided, however, that such entity cannot be an affiliate of the Seller, the Depositor or the Servicer other than the Trustee in its role as successor to the 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 Seller, the Servicer 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 the Trustee gives notice of such resignation, the Depositor shall promptly appoint a successor trustee. 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 of resignation or removal (as provided below), the resigning or removed 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 the provisions of 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 appoint a successor trustee by written instrument, in a sufficient number of copies to provide one copy of to the Trustee, one copy to the Servicer, one copy to the Seller and one copy to the successor trustee.

The Holders of Certificates entitled to at least 51% of the Voting Rights may at any time remove the Trustee and 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 the Depositor, the Servicer and the Seller, one complete set to the Trustee so removed and one complete set to the successor so appointed. Notice of any removal of the Trustee shall be given to each Rating Agency by the successor trustee.

Any resignation or removal of the Trustee and appointment of a successor trustee pursuant to any of the provisions of 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, the Servicer and the Seller 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 the like effect as if originally named as trustee herein. The Depositor, the Servicer, the Seller 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 such acceptance such successor trustee shall be eligible under the provisions of Section 8.06 and its appointment shall not adversely affect the then 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 the provisions of 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 Depositor and the Trustee acting jointly 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 Depositor and the Trustee may consider necessary or desirable. If the Depositor shall not have joined in such appointment within 15 days after the receipt by it of a request to do so, or in the case an Event of Default shall have occurred and be continuing, the Trustee alone shall have the power to make such appointment. No co-trustee or separate trustee hereunder shall be required to meet the terms of eligibility as a successor trustee under Section 8.06 and no notice to Certificateholders of the appointment of any co-trustee or separate trustee shall be required under Section 8.08.

Every separate trustee and co-trustee shall, to the extent permitted by law, be appointed and act subject to the following provisions and conditions:

(i)

To the extent necessary to effectuate the purposes of this Section 8.10, all rights, powers, duties and obligations conferred or imposed upon the Trustee, except for the obligation of the Trustee in its capacity as successor servicer under this Agreement to advance funds on behalf of the 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 set or acts are to be performed (whether as Trustee hereunder or as successor to the 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;

(ii)

No trustee hereunder shall be held personally liable by reason of any act or omission of any other trustee hereunder and such appointment shall not, and shall not be deemed to, constitute any such separate trustee or co-trustee as agent of the Trustee;

(iii)

The Trustee may at any time accept the resignation of or remove any separate trustee or co-trustee; and

(iv)

The Depositor, 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 to, the Trustee. Every such instrument shall be filed with the Trustee and a copy thereof given to the 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

Tax Matters.

It is intended that the assets with respect to which any REMIC election is to be made, as set forth in the Preliminary Statement, shall constitute, and that the conduct of matters relating to such assets shall be such as to qualify such assets as, multiple “real estate mortgage investment conduits” as defined in and in accordance with the REMIC Provisions. In furtherance of such intention, the Trustee covenants and agrees that it shall act as agent (and the Trustee is hereby appointed to act as agent) on behalf of the REMICs and that in such capacity it shall: (a) prepare, sign and file, or cause to be prepared and filed, in a timely manner, a U.S. Real Estate Mortgage Investment Conduit Income Tax Return (Form 1066 or any successor form adopted by the Internal Revenue Service) and prepare and file or cause to be prepared and filed with the Internal Revenue Service and applicable state or local tax authorities income tax or information returns for each taxable year with respect to each REMIC, containing such information and at the times and in the manner as may be required by the Code or state or local tax laws, regulations, or rules, and furnish or cause to be furnished to Certificateholders the schedules, statements or information at such times and in such manner as may be required thereby; (b) within thirty days of the Closing Date, furnish or cause to be furnished to the Internal Revenue Service, on Forms 8811 or as otherwise may be required by the Code, the name, title, address, and telephone number of the person that the holders of the Certificates may contact for tax information relating thereto, together with such additional information as may be required by such form, and update such information at the time or times in the manner required by the Code; (c) make or cause to be made elections that each group of segregated assets be treated as a REMIC on the federal tax return for its first taxable year (and, if necessary, under applicable state law) and apply for an employee identification number from the IRS via a Form SS-4 or any other acceptable method for all tax entities; (d) prepare and forward, or cause to be prepared and forwarded, to the Certificateholders and to the Internal Revenue Service and, if necessary, state tax authorities, all information returns and reports as and when required to be provided to them in accordance with the REMIC Provisions, including without limitation, the calculation of any original issue discount using the Prepayment Assumption; (e) provide information necessary for the computation of tax imposed on the transfer of a Residual Certificate to a Person that is not a Permitted Transferee, or an agent (including a broker, nominee or other middleman) of a Non-Permitted Transferee, or a pass-through entity in which a Non-Permitted Transferee is the record holder of an interest (the reasonable cost of computing and furnishing such information may be charged to the Person liable for such tax); (f) to the extent that they are under its control, conduct matters relating to such assets at all times that any Certificates are outstanding so as to maintain the status of any REMIC as a REMIC under the REMIC Provisions; (g) not knowingly or intentionally take any action or omit to take any action that would cause the termination of the REMIC status of any REMIC hereunder; (h) pay, from the sources specified in the sixth paragraph of this Section 8.11, the amount of any federal or state tax, including prohibited transaction taxes as described below, imposed on any REMIC hereunder prior to its termination when and as the same shall be due and payable (but such obligation shall not prevent the Trustee or any other appropriate Person from contesting any such tax in appropriate proceedings and shall not prevent the Trustee from withholding payment of such tax, if permitted by law, pending the outcome of such proceedings); (i) ensure that federal, state or local income tax or information returns shall be signed by the Trustee or such other person as may be required to sign such returns by the Code or state or local laws, regulations or rules; (j) maintain records relating to the REMICs, including but not limited to the income, expenses, assets and liabilities thereof and the fair market value and adjusted basis of the assets determined on the accrual method or at such internals as may be required by the Code, as may be necessary to prepare the foregoing returns, schedules, statements or information; and (k) as and when necessary and appropriate, represent any such REMIC in any administrative or judicial proceedings relating to an examination or audit by any governmental taxing authority, request an administrative adjustment as to any taxable year of any REMIC, enter into settlement agreements with any governmental taxing agency, extend any statute of limitations relating to any tax item of any such REMIC, and otherwise act on behalf of the REMICs in relation to any tax matter or controversy involving it.

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

In the event that any tax is imposed on “prohibited transactions” of any REMIC as defined in Section 860F(a)(2) of the Code, on the “net income from foreclosure property” of any REMIC as defined in Section 860G(c) of the Code, on any contribution to the REMICs after the Startup Day pursuant to Section 860G(d) of the Code, or any other tax is imposed, including, without limitation, any minimum tax imposed upon any REMICs pursuant to Sections 23153 and 24874 of the California Revenue and Taxation Code, if not paid as otherwise provided for herein, such tax shall be paid by (i) the Trustee, if any such other tax arises out of or results from a breach by the Trustee of any of its obligations under this Agreement, (ii) the Seller, in the case of any such minimum tax, if such tax arises out of or results from a breach by the Seller of any of its obligations under this Agreement or (iii) the Seller, if any such tax arises out of or results from the Seller’s obligation to repurchase a related Mortgage Loan pursuant to Section 2.02 or 2.03 or (iv) in all other cases, or in the event that the Trustee or the Seller fails to honor its obligations under the preceding clauses (i), (ii) or (iii) or the Servicer fails to honor its obligations pursuant to Section 8.15, any such tax will be paid with amounts otherwise to be distributed to the Certificateholders, as provided in Section 3.09(b).

The Trustee shall treat the Basis Risk Reserve Fund as an outside reserve fund within the meaning of Treasury Regulation 1.860G-2(h) that is owned by the Class X Certificateholder, and not as an asset of any REMIC. The Trustee shall treat the rights of the Class A, Class M and Class B Certificateholders to receive interest payments reflecting an interest rate greater than the REMIC Maximum Rate, including payments from the Basis Risk Reserve Fund, as rights in an interest rate cap contract written by the Class X Certificateholder in favor of the Class A, Class M and Class B Certificateholders. Thus, each Class A, Class M and Class B Certificate shall be treated as representing ownership of not only REMIC regular interests, but also ownership of an interest in interest rate cap contracts or a separate contractual right. For purposes of determining the issue price of the REMIC regular interests represented by the Class A, Class M and Class B Certificates, the Trustee shall assume that rights of the Holders of such Certificates to receive amounts reflecting an interest rate greater than the REMIC Maximum Rate, including interest payments from the Basis Risk Reserve Fund, has a value of $10,000 as of the Closing Date.

The Trustee, the Servicer and the Holders of Certificates shall take any action or cause any REMIC to take any action necessary to create or maintain the status of each REMIC as a REMIC under the REMIC Provisions and shall assist each other as necessary to create or maintain such status. Neither the Trustee, the Servicer nor the Holder of any Residual Certificate shall knowingly take any action, cause any REMIC created hereunder to take any action or fail to take (or fail to cause to be taken) any action that, under the REMIC Provisions, if taken or not taken, as the case may be, could (i) endanger the status of any REMIC as a REMIC or (ii) result in the imposition of a tax upon any REMIC (including but not limited to the tax on prohibited transactions as defined in Code Section 860F(a)(2) and the tax on prohibited contributions set forth on Section 860G(d) of the Code) (either such event, an “Adverse REMIC Event”) unless the Trustee and the Servicer have received an Opinion of Counsel (at the expense of the party seeking to take such action) to the effect that the contemplated action will not endanger such status or result in the imposition of such a tax.

Each Holder of a Residual Certificate shall pay when due any and all taxes imposed on each REMIC created hereunder by federal or state governmental authorities. To the extent that such Trust taxes are not paid by a Residual Certificateholder, the Trustee shall pay any remaining REMIC taxes out of current or future amounts otherwise distributable to the Holder of the Residual Certificate in the REMICs or, if no such amounts are available, out of other amounts held in the Distribution Account, and shall reduce amounts otherwise payable to Holders of regular interests in the related REMIC.

The Trustee shall, for federal income tax purposes, maintain books and records with respect to each REMIC created hereunder on a calendar year and on an accrual basis.

The Trustee will apply for an Employee Identification Number from the Internal Revenue Service via a Form SS-4 or other acceptable method for all tax entities.

It is the intent of the parties hereto that the segregated pool of assets consisting of any collections in respect of the Prepayment Premiums payable to the Class P Certificates constitutes, for federal income tax purposes, a grantor trust as described in Subpart E of Part I of Subchapter J of the Code and Treasury Regulation §301.7701-4(c)(2). The Trustee shall prepare, sign and file all of the tax returns in respect of such grantor trust. The expenses of preparing and filing such returns shall be borne by the Trustee without any right of reimbursement therefor. The Trustee shall comply with each such requirement by filing Form 1041 or other applicable form.

The Trustee and the Servicer shall reasonably cooperate with the Depositor in connection with the Trust’s satisfying the reporting requirements under the Exchange Act. The Trustee shall prepare on behalf of the Depositor any Forms 8-K and 10-K customary for similar securities as required by the Exchange Act and the rules and regulations of the Commission thereunder, and the Depositor shall sign and the Trustee shall file (via EDGAR) such Forms on behalf of the Depositor. The Depositor hereby grants to the Trustee a limited power of attorney to execute and file each such document on behalf of the Depositor. Such power of attorney shall continue until the earlier of (i) receipt by the Trustee from the Depositor of written termination of such power of attorney and (ii) the termination of the Trust.

(b)

Each Form 8-K shall be filed by the Trustee within 15 days after each Distribution Date, with a copy of the statement to the Certificateholders for such Distribution Date as an exhibit thereto. Prior to March 31st of the calendar year following the calendar year during which the Closing Date occurs (or such earlier date as may be required by the Exchange Act and the rules and regulations of the Commission), the Trustee shall file a Form 10-K, in substance as required by applicable law or applicable Commission staff’s interpretations. Such Form 10-K shall include as exhibits, the Servicer’s annual statement of compliance described under Section 3.17 and each accountant’s report described under Section 3.18, in each case to the extent they have been timely delivered to the Trustee. If they are not so timely delivered, the Trustee shall file an amended Form 10-K including such documents as exhibits promptly after they are delivered to the Trustee. The Trustee shall have no liability with respect to any failure to properly or timely prepare or file such periodic reports resulting from or relating to the Trustee’s inability or failure to obtain any information not resulting from its own negligence or willful misconduct. The Form 10-K shall also include a certification in the form attached hereto as Exhibit U (the “Depositor Certification”), which shall be signed by the senior officer of the Depositor in charge of securitization. Not later than 5 Business Days before the date on which the Depositor’s annual report on Form 10-K is required to be filed in accordance with the Exchange Act and the rules and regulations of the Commission, the Depositor will deliver to the Trustee a form of the Depositor Certification. The Depositor shall subsequently deliver to the Trustee the executed Depositor Certification no later than the date on which the annual report on Form 10-K is required to be filed. The Trustee shall have no responsibility to file any items other than those specified in this Section 8.12.

(c)

Not later than 15 calendar days before the date on which the Depositor’s annual report on Form 10-K is required to be filed in accordance with the Exchange Act and the rules and regulations of the Commission (or, if such day is not a Business Day, the immediately preceding Business Day, the Trustee shall sign a certification in the form attached hereto as Exhibit V (the “Trustee Certification”) for the benefit of the Depositor and its officers, directors and affiliates regarding certain aspects of items 1 through 3 of the Depositor Certification. In addition, the Trustee shall, subject to the provisions of Sections 8.01 and 8.02 hereof, indemnify and hold harmless the Depositor, the Servicer, each Person, if any, that “controls” the Depositor, the Servicer within the meaning of the Securities Act and their respective officers, directors and affiliates from and against any losses, damages, penalties, fines, forfeitures, reasonable and necessary legal fees and related costs, judgments and other costs and expenses arising out of or based upon a breach of the Trustee’s obligations under this Section 8.12 or any inaccuracy made in the Trustee Certification. If the indemnification provided for in this Section 8.12(c) is unavailable or insufficient to hold harmless such Persons, then the Trustee shall contribute to the amount paid or payable by such Persons as a result of the losses, claims, damages or liabilities of such Persons in such proportion as is appropriate to reflect the relative fault of the Depositor or the Servicer on the one hand and the Trustee on the other. The Trustee acknowledges that the Depositor is relying on the Trustee’s performance of its obligations under this Section 8.12 in order to perform its obligations under Section 8.12(b) above.

(d)

Not later than 15 calendar days before the date on which the Depositor’s annual report on Form 10-K is required to be filed in accordance with the Exchange Act and the rules and regulations of the Commissions (or, if such day is not a Business Day, the immediately preceding Business Day) the Servicer will deliver to the Depositor and the Trustee an Officer’s Certificate for the prior calendar year, substantially in the form attached hereto as Exhibit W (the “Servicer Certification”). The Servicer agrees to indemnify and hold harmless each of the Depositor, the Trustee, each Person, if any, who “controls” the Depositor or the Trustee within the meaning of the Securities Act and their respective officers, directors and affiliates from and against any losses, damages, penalties, fines, forfeitures, reasonable and necessary legal fees and related costs, judgments and other costs and expenses that such Person may sustain arising out of third party claims based on (i) the failure of the Servicer to deliver or cause to be delivered when required any Officer’s Certificate required pursuant to this Section 8.12(d), or (ii) any material misstatement or omission contained in any Officer’s Certificate provided pursuant to this Section 8.12(d). If an event occurs that would otherwise result in an indemnification obligation under clauses (i) or (ii) above, but the indemnification provided for in this Section 8.12(d) by the Servicer is unavailable or insufficient to hold harmless such Persons, then the Servicer shall contribute to the amount paid or payable by such Persons as a result of the losses, claims, damages or liabilities of such Persons in such proportion as is appropriate to reflect the relative fault of the Depositor or the Trustee on the one hand and the Servicer on the other. The Servicer acknowledges that the Depositor and the Trustee are relying on the Servicer’s performance of its obligations under this Agreement in order to perform their respective obligations under this Section 8.12.

(e)

Upon any filing with the Commission, the Trustee shall promptly deliver to the Depositor and the Servicer a copy of any executed report, statement or information.

(f)

If the Commission issues additional interpretative guidance or promulgates additional rules or regulations, or if other changes in applicable law occur, that would require the reporting arrangements, or the allocation of responsibilities with respect thereto, described in this Section 8.12, to be conducted differently than as described, the Depositor, the Servicer and the Trustee will reasonably cooperate to amend the provisions of this Section 8.12 in order to comply with such amended reporting requirements and such amendment of this Section 8.12. Any such amendment shall be made in accordance with Section 10.01 without the consent of the Certificateholders, and may result in a change in the reports filed by the Trustee on behalf of the Trust under the Exchange Act. Notwithstanding the foregoing, the Depositor, the Servicer and the Trustee shall not be obligated to enter into any amendment pursuant to this Section 8.12 that adversely affects its obligations and immunities under this Agreement.

(g)

Prior to January 31 of the first year in which the Trustee is able to do so under applicable law, the Trustee shall file a Form 15D Suspension Notification with respect to the Trust.

SECTION 8.13

Trust Obligations.

For all purposes herein, any and all rights, duties and obligations of the Trustee on behalf of the Trust shall be the rights, duties and obligations of the Trust itself.

SECTION 8.14

Determination of Certificate Index.

On each Interest Determination Date, the Trustee shall determine the Certificate Index for the Accrual Period and inform the Servicer of such rate.

SECTION 8.15

Indemnification with Respect to Certain Taxes and Loss of REMIC Status.

In the event that any REMIC fails to qualify as a REMIC, loses its status as a REMIC, or incurs federal, state or local taxes as a result of a prohibited transaction or prohibited contribution under the REMIC Provisions due to the negligent performance by the Servicer of its duties and obligations set forth herein, the Servicer shall indemnify the Trustee and the Trust Fund against any and all losses, claims, damages, liabilities or expenses (“Losses”) resulting from such negligence; provided, however, that the Servicer shall not be liable for any such Losses attributable to the negligence of the Trustee, the Depositor or the Holder of such Class R or Class R-II Certificate, as applicable, nor for any such Losses resulting from misinformation provided by the Holder of such Class R or Class R-II Certificate on which the Servicer has relied. The foregoing shall not be deemed to limit or restrict the rights and remedies of the Holder of such Class R or Class R-II Certificate now or hereafter existing at law or in equity. Notwithstanding the foregoing, however, in no event shall the Servicer have any liability (1) for any action or omission that is taken by it in accordance with and in compliance with the express terms of, or which is expressly permitted by the terms of, this Agreement, (2) for any Losses other than arising out of a negligent performance by the Servicer of its duties and obligations set forth herein, and (3) for any special or consequential damages to Certificateholders (in addition to payment of principal and interest on the Certificates).

ARTICLE IX

TERMINATION

SECTION 9.01

Termination upon Liquidation, Purchase or Auction of the Mortgage Loans.

Subject to Section 9.03, the obligations and responsibilities of the Depositor, the Seller, the Servicer and the Trustee created hereunder with respect to the Trust Fund shall terminate upon the earlier of:

(A) the purchase by the Terminating Entity of all Mortgage Loans (and REO Properties) remaining at the price equal to the greater of (I) the sum of (i) 100% of the Stated Principal Balance of each Mortgage Loan (other than in respect of REO Property) plus one month’s accrued interest thereon at the applicable Mortgage Rate, (ii) with respect to any REO Property, the lesser of (x) the appraised value of any REO Property as determined by the higher of two appraisals completed by two independent appraisers selected by the Depositor at the expense of the Depositor and (y) the Stated Principal Balance of each Mortgage Loan related to any REO Property, in each case and related to any REO Property, in each case plus accrued and unpaid interest thereon at the applicable Mortgage Rate and (iii) any unreimbursed Advances, Servicing Advances, Servicing Fees and Trustee Fees payable to the Servicer or the Trustee, as applicable, which shall be entitled to withdraw such amounts from the applicable Collection Account pursuant to Section 3.09(a) (the sum of (i), (ii) and (iii), collectively, the “Par Value”) and (II) the Fair Market Value.

The “Fair Market Value” shall be the fair market value of all of the property of the Trust, as agreed upon between the Terminating Entity and a majority of the holders of the Class R-II Certificates; provided, however, that if the Terminating Entity and a majority of the holders of the Class R-II Certificates do not agree upon the fair market value of all the property of the Trust, the Trustee, shall solicit bids for all of the property of the Trust until it has received three bids, and the Fair Market Value shall be equal to the highest of such three bids.

(B) the later of (i) the maturity or other liquidation (or any Advance with respect thereto) of the last Mortgage Loan remaining in the Trust Fund and the disposition of all REO Property and (ii) the distribution to Certificateholders of all amounts required to be distributed to them pursuant to this Agreement.

(C) the purchase by the Auction Purchaser of all the Mortgage Loans and all property acquired in respect of any remaining Mortgage Loan (the “Trust Collateral”) as described below.

In no event shall the trusts created hereby continue beyond the expiration of (i) 21 years from the death of the survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James’s, living on the date hereof or (ii) the Distribution Date in May 2035.

The right to repurchase all Mortgage Loans and REO Properties pursuant to clause (A) above shall be conditioned upon (x) if no NIM Note is outstanding, the aggregate Stated Principal Balance of the Mortgage Loans, at the time of any such repurchase, aggregating less than ten percent (10%) of the Aggregate Collateral Balance as of the Initial Cut-off Date and (y) if any NIM Note is outstanding, the aggregate Stated Principal Balance of the Mortgage Loans, at the time of any such repurchase, aggregating less than five percent (5%) of the Aggregate Collateral Balance as of the Initial Cut-off Date.

On any Distribution Date on or after the date on which the aggregate Principal Balance of the Mortgage Loans at the time of the purchase is less than 5% of the aggregate Principal Balance of the Mortgage Loans as of the Initial Cut-off Date (the “Auction Date”), the Trustee shall solicit bids for the Trust Collateral from at least three institutions that are regular purchasers and/or sellers in the secondary market of residential whole mortgage loans similar to the Mortgage Loans. If the Trustee receives at least three bids for the Trust Collateral, and one of such bids is equal to or greater than the Par Value plus the Trustee Auction Fee, the Trustee shall sell the Trust Collateral to the highest bidder (the “Auction Purchaser”) at the price offered by the Auction Purchaser (the “Mortgage Loan Purchase Price”). If the Trustee receives less than three bids, or does not receive any bid that is equal to or greater than the Par Value plus the Trustee Auction Fee, the Trustee shall, on each six-month anniversary of the initial Auction Date, repeat these auction procedures until the Trustee receives a bid that is equal to or greater than the Par Value plus the Trustee Auction Fee, and sells the Trust Collateral to the Auction Purchaser at the Mortgage Loan Purchase Price. The Trustee shall give notice to the Rating Agencies of the sale of the Trust Collateral pursuant to this Section 9.01 and of the Auction Date.

SECTION 9.02

Final Distribution on the Certificates.

If on any Determination Date, the Trustee determines that there are no Outstanding Mortgage Loans and no other funds or assets in the Trust Fund other than the funds in the Collection Accounts and Certificate Account, the Trustee shall promptly send a final distribution notice to each Certificateholder. If the Terminating Entity elects to terminate the Trust Fund or the Auction Purchaser purchases the Mortgage Loans pursuant to Section 9.01, at least 20 days prior to the date notice is to be mailed to the affected Certificateholders, the Terminating Entity or the Auction Purchaser, as applicable, shall notify the Rating Agencies and the Trustee of the date it intends to terminate the Trust Fund and of the applicable repurchase price of the Mortgage Loans and REO Properties.

Notice of any termination of the Trust Fund, specifying the Distribution Date on which Certificateholders may surrender their Certificates for payment of the final distribution and cancellation, shall be given promptly by the Trustee by letter to Certificateholders mailed not earlier than the 15th day and not later than the 25th day of the month next preceding the month of such final distribution. Any such notice shall specify (a) the Distribution Date upon which final distribution on the Certificates will be made upon presentation and surrender of Certificates at the office therein designated, (b) the amount of such final distribution, (c) the location of the office or agency at which such presentation and surrender must be made, and (d) that the Record Date otherwise applicable to such Distribution Date is not applicable, distributions being made only upon presentation and surrender of the Certificates at the office therein specified. The Trustee shall give such notice to each Rating Agency at the time such notice is given to Certificateholders.

On the final Distribution Date, the Trustee shall cause to be distributed to the Certificateholders of each Class, upon presentation and surrender of the Certificates, and to the Trustee and the Credit Risk Manager distributions and payments in accordance with Section 4.02. Notwithstanding the foregoing, if the final Distribution Date has occurred as a result of a Terminating Entity’s purchase of the Trust Fund pursuant to Section 9.01(A), all amounts, if any, in excess of the Par Value shall be distributed by the Trustee directly to the Class X Certificates.

In the event that any affected Certificateholders shall not surrender Certificates for cancellation within six months after the date specified in the above mentioned written notice, the Trustee shall give a second written notice to the remaining Certificateholders to surrender their Certificates for cancellation and receive the final distribution with respect thereto. If within six months after the second notice all the applicable Certificates shall not have been surrendered for cancellation, the Trustee may take reasonable and appropriate steps, or may appoint an agent to take reasonable and appropriate steps, to contact the remaining Certificateholders concerning surrender of their Certificates, and the cost thereof shall be paid out of the funds and other assets which remain a part of the Trust Fund. If within one year after the second notice all Certificates shall not have been surrendered for cancellation, the Class R and Class R-II Certificateholders shall be entitled to all unclaimed funds and other assets of the Trust Fund which remain subject hereto and the Trustee shall be discharged from all further liability with respect to the Certificates and this Agreement.

SECTION 9.03

Additional Termination Requirements.

(a)

In the event the Terminating Entity exercises its purchase option with respect to the Mortgage Loans as provided in Section 9.01 or the Trust Collateral is purchased pursuant to the auction procedures contained in Section 9.01, at such time as the Mortgage Loans are so purchased, the Trust Fund shall be terminated in accordance with the following additional requirements, unless the Trustee has been provided with an Opinion of Counsel, at the expense of the Terminating Entity, to the effect that the failure to comply with the requirements of this Section 9.03 will not (i) result in the imposition of taxes on “prohibited transactions” on any REMIC as defined in Section 860E of the Code, or (ii) cause any REMIC to fail to qualify as a REMIC at any time that any Certificates are outstanding:

(1)

Within 90 days prior to the final Distribution Date set forth in the notice given by the Trustee under Section 9.02, the Depositor shall prepare and the Trustee shall adopt a plan of complete liquidation within the meaning of Section 860F(a)(4) of the Code which, as evidenced by an Opinion of Counsel (which opinion shall not be an expense of the Trustee or the Trust Fund), meets the requirements of a qualified liquidation;

(2)

Within 90 days after the time of adoption of such a plan of complete liquidation, the Trustee shall sell all of the assets of the Trust Fund to the purchaser for cash in accordance with Section 9.01; and

(3)

On the date specified for final payment of the Certificates, the Trustee shall, after payment of any unreimbursed Advances, Servicing Advances, Servicing Fees or other fee compensation payable to the Servicer pursuant to this Agreement, make final distributions of principal and interest on the Certificates in accordance with Section 4.02 and distribute or credit, or cause to be distributed or credited, to the Holders of the Residual Certificates all cash on hand after such final payment (other than the cash retained to meet claims), and the Trust Fund (and each REMIC) shall terminate at that time.

(b)

The Trustee as agent for each REMIC hereby agrees to adopt and sign such a plan of complete liquidation upon the written request of the Depositor, and the receipt of the Opinion of Counsel referred to in Section 9.03(a)(1) and to take such other action in connection therewith as may be reasonably requested by the Depositor.

(c)

By their acceptance of the Certificates, the Holders thereof hereby authorize the Depositor to prepare and the Trustee to adopt and sign a plan of complete liquidation.

ARTICLE X

MISCELLANEOUS PROVISIONS

SECTION 10.01

Amendment.

This Agreement may be amended from time to time by the Depositor, the Servicer, the Seller and the Trustee without the consent of any of the Certificateholders (i) to cure any ambiguity or mistake, (ii) to correct any defective provision herein or to supplement any provision herein which may be inconsistent with any other provision herein, (iii) to add to the duties of the Depositor, the Seller or the Servicer, (iv) in connection with the appointment of a successor Servicer, to modify, eliminate or add to any of the servicing or master servicing provisions contained in this Agreement, providing the Rating Agencies confirm the then current rating of the Certificates giving effect to such amendment, (v) to add any other provisions with respect to matters or questions arising hereunder or (vi) to modify, alter, amend, add to or rescind any of the terms or provisions contained in this Agreement; and, provided, further, that any action pursuant to clauses (v) or (vi) above shall not, as evidenced by an Opinion of Counsel (which Opinion of Counsel shall not be an expense of the Trustee or the Trust Fund, but shall be at the expense of the party proposing such amendment), adversely affect in any material respect the interests of any Certificateholder; provided, however, that no such Opinion of Counsel shall be required if the Person requesting the amendment obtains a letter from each Rating Agency stating that the amendment would not result in the downgrading or withdrawal of the respective ratings then assigned to the Certificates. The Trustee, the Depositor, the Seller and the Servicer also may at any time and from time to time amend this Agreement 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 any REMIC as a REMIC under the Code, (ii) avoid or minimize the risk of the imposition of any tax on any REMIC 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 has 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.

Except as provided in the immediately following paragraph, this Agreement may also be amended from time to time by the Depositor, the Servicer, the Seller and the Trustee with the consent of the Holders of each Class of Certificates affected thereby evidencing 66% of the aggregate Class Principal Balance of such Class for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Agreement or of modifying in any manner the rights of the Holders of Certificates; provided, however, that no such amendment shall (i) reduce in any manner the amount of, or delay the timing of, payments required to be distributed on any Certificate without the consent of the Holder of such Certificate, or (ii) reduce the aforesaid percentages of Certificates the Holders of which are required to consent to any such amendment, without the consent of the Holders of all such Certificates then outstanding.

Notwithstanding any contrary provision of this Agreement, the Trustee shall not consent to any amendment to this Agreement unless it shall have first received an Opinion of Counsel, which opinion shall not be an expense of the Trustee or the Trust Fund, but shall be at the expense of the party requesting such amendment, to the effect that such amendment will not cause the imposition of any federal tax on any REMIC or the Certificateholders or cause any REMIC to fail to qualify as a REMIC at any time that any Certificates are outstanding.

Promptly after the execution of any amendment to this Agreement requiring the consent of Certificateholders, the Trustee shall furnish written notification of the substance or a copy of such amendment to each Certificateholder and each Rating Agency.

It shall not be necessary for the consent of Certificateholders under this Section 10.01 to approve the particular form of any proposed amendment, but it shall be sufficient if such consent shall approve the substance thereof. The manner of obtaining such consents and of evidencing the authorization of the execution thereof by Certificateholders shall be subject to such reasonable regulations as the Trustee may prescribe.

Nothing in this Agreement shall require the Trustee to enter into an amendment without receiving an Opinion of Counsel (which Opinion shall not be an expense of the Trustee or the Trust Fund), satisfactory to the Trustee that (i) such amendment is permitted and is not prohibited by this Agreement and that all requirements for amending this Agreement have been complied with; and (ii) either (A) the amendment does not adversely affect in any material respect the interests of any Certificateholder or (B) the conclusion set forth in the immediately preceding clause (A) is not required to be reached pursuant to this Section 10.01. The Trustee shall have no obligation to consent to any amendment that it reasonably believes will materially and adversely affect its rights or immunities under this Agreement.

SECTION 10.02

Recordation of Agreement; Counterparts.

This Agreement is subject to recordation in all appropriate public offices for real property records in all the counties or other comparable jurisdictions in which any or all of the properties subject to the Mortgages are situated, and in any other appropriate public recording office or elsewhere, such recordation to be effected by the Depositor at its expense, but only upon direction by the Trustee (acting at the direction of holders of Certificates evidencing a majority of the aggregate Class Principal Balance) accompanied by an Opinion of Counsel (at the Depositor’s expense) to the effect that such recordation materially and beneficially affects the interests of the Certificateholders.

For the purpose of facilitating the recordation of this Agreement as herein provided and for other purposes, this Agreement may be executed simultaneously in any number of counterparts, each of which counterparts shall be deemed to be an original, and such counterparts shall constitute but one and the same instrument.

SECTION 10.03

Governing Law.

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

SECTION 10.04

Intention of Parties.

It is the express intent of the parties hereto that the conveyance of the Trust Fund, including the Mortgage Loans, by the Depositor to the Trustee be, and be construed as, an absolute sale thereof. It is, further, not the intention of the parties that such conveyance be deemed a pledge thereof. However, in the event that, notwithstanding the intent of the parties, such assets are held to be the property of the Depositor, or if for any other reason this Agreement is held or deemed to create a security interest in either such assets to secure payment or performance of an obligation, then the Depositor for the benefit of the Certificateholders shall, to the extent consistent with this Agreement, take such actions as may be necessary to ensure that the Trustee for the benefit of the Certificateholders shall have and shall continue to have a perfected security interest to secure payment or performance of an obligation of first priority under applicable law throughout the term of the Agreement. The Depositor shall arrange for filing any Uniform Commercial Code financing statements and continuation statements in connection with such security interest.

The repurchase or substitution of Mortgage Loans pursuant to Sections 2.02 and 2.03; and

The final payment to Certificateholders.

In addition, the Trustee shall promptly furnish to each Rating Agency copies of the following:

Each report to Certificateholders described in Section 4.05 and 3.21;

Each annual statement as to compliance described in Section 3.17;

Each annual independent public accountants’ servicing report described in Section 3.18; and

SECTION 10.06

Severability of Provisions.

If any one or more of the covenants, agreements, provisions or terms of this Agreement shall be for any reason whatsoever held invalid, then such covenants, agreements, provisions or terms shall be deemed severable from the remaining covenants, agreements, provisions or terms of this Agreement and shall in no way affect the validity or enforceability of the other provisions of this Agreement or of the Certificates or the rights of the Holders thereof.

SECTION 10.07

Assignment.

Notwithstanding anything to the contrary contained herein, except as provided in Sections 3.22, 6.02 and 6.04, this Agreement may not be assigned by the Servicer without the prior written consent of the Trustee and Depositor.

SECTION 10.08

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% 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 10.08, each and every Certificateholder and the Trustee shall be entitled to such relief as can be given either at law or in equity.

SECTION 10.09

Certificates Nonassessable and Fully Paid.

It is the intention of the Depositor that Certificateholders shall not be personally liable for obligations of the Trust Fund, that the interests in the Trust Fund represented by the Certificates shall be nonassessable for any reason whatsoever, and that the Certificates, upon due authentication thereof by the Trustee pursuant to this Agreement, are and shall be deemed fully paid.

SECTION 10.10

Protection of Assets.

(a)

Except for transactions and activities entered into in connection with the securitization that is the subject of this agreement, the trust created by this agreement is not authorized and has no power to:

(b)

Each party to this agreement agrees that it will not file an involuntary bankruptcy petition against the Trust Fund or initiate any other form of insolvency proceeding until after the Certificates have been paid.

SECTION 10.11

Non-Solicitation.

From and after the date of this Agreement, each of the Depositor, the Seller, the Servicer and the Trustee agrees that it will not take any action or permit or cause any action to be taken by any of its agents or affiliates, or by any independent contractors on any such party's behalf, to personally, by telephone, by mail, or electronically by e-mail or through the internet or otherwise, solicit the borrower or obligor under any Mortgage Loan to refinance the Mortgage Loan, in whole or in part. Notwithstanding the foregoing, it is understood and agreed that promotions undertaken by the Depositor, the Seller, the Servicer or the Trustee or any affiliate of any such party that originates mortgage loans in the normal course of business, which are directed to the general public at large, or segments thereof, including, without limitation, mass mailings based on commercially acquired mailing lists or newspaper, internet, company website, radio and television advertisements shall not constitute solicitation under this Section 10.11, provided, that no segment of the general public shall consist primarily of the borrowers or obligors under the Mortgage Loans. None of the Depositor, the Seller, the Servicer or the Trustee shall permit the sale of the name of any Mortgagor or any list of names that consist primarily of the Mortgages to any Person.

IN WITNESS WHEREOF, the Depositor, the Trustee, the Seller, the Credit Risk Manager and the Servicer have caused their names to be signed hereto by their respective officers thereunto duly authorized as of the day and year first above written.
