PRELIMINARY STATEMENT

As provided herein, the Trust Administrator shall elect that the Trust Fund (exclusive of the assets held in the the Prefunding Account and the Capitalized Interest Account, and exclusive of any Prepayment Penalties) be treated for federal income tax purposes as comprising five real estate mortgage investment conduits (each a “REMIC” or, in the alternative, “Subsidiary REMIC 1,” “Subsidiary REMIC 2,” “Middle REMIC 1,” “Middle REMIC 2,” and “Master REMIC”). Each Class of Certificates, other than the Class AR and Class AR-L Certificates, represents ownership of a regular interest in the Master REMIC for purposes of the REMIC Provisions. The Class AR Certificates represent ownership of the sole class of residual interest in each of Middle REMIC 1, Middle REMIC 2 and the Master REMIC for purposes of the REMIC Provisions. The Class AR-L Certificates represent ownership of the sole class of residual interest in Subsidiary REMIC 1 and Subsidiary REMIC 2 for purposes of the REMIC Provisions. The Master REMIC shall hold as its assets the several classes of uncertificated Middle Tier Interests in Middle REMIC 2 other than the Class MT2-R Interest, and each such Middle Tier Interest is hereby designated as a regular interest in Middle REMIC 2. Middle REMIC 2 shall hold as its assets the several classes of uncertificated Middle Tier Interests in Middle REMIC 1 other than the Class MT1 R Interest, and each such Middle Tier Interest is hereby designated as a regular interest in Middle REMIC 1. Middle REMIC 1 shall hold as its assets the several classes of uncertificated Lower Tier Interests in Subsidiary REMIC 1 and Subsidiary REMIC 2, other than the Class LT1-R and Class LT2-R Interests, and each such Lower Tier Interest is hereby designated as a regular interest in a Subsidiary REMIC. Subsidiary REMIC 1 shall hold as its assets the Mortgage Loans in Loan Group I and Loan Group II, and all collections and accounts related thereto. Subsidiary REMIC 2 shall hold as its assets the Mortgage Loans in Loan Group III and Loan Group IV, and all collections and accounts related thereto. 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 Distribution Date following the third anniversary of the scheduled maturity date of the Mortgage Loan having the latest scheduled maturity date as of the Cut-off Date.

The Class MT1-R Interest is the sole class of residual interest in Middle REMIC 1. It does not have an interest rate or a principal balance.

On each Distribution Date, the Trust Administrator shall allocate interest (in an amount equal to the aggregate amount of interest distributable on such Distribution Date with respect to the Mortgage Loans) to the Interests in Middle REMIC 1 at the rates shown above, pro rata, based on the amount of interest accrued on each such Interest for the related Interest Accrual Period; provided, however, that interest that accrues on the Class MT1-Grp-I-II Interest shall be deferred to the extent necessary to make the principal distributions described below on the Class MT1-GSA-CB-1 and Class MT1-GSA-CB-2 Interests, and interest that accrues on the Class MT1-Grp-III-IV Interest shall be deferred to the extent necessary to make the principal distributions described below on the Class MT1-GSA-DB-1 and Class MT1-GSA-DB-2 Interests. Any interest so deferred on the Class MT1-Grp-I-II or Class MT1-Grp-III-IV Interest shall itself bear interest at the interest rate of the Class MT1-Grp-I-II or Class MT1-Grp-III-IV Interest, respectively.

On each Distribution Date, principal collections and realized losses with respect to the Mortgage Loans in Loan Group I and Loan Group II (and deferred interest on the Class MT1-Grp-I-II Interest to the extent provided below) shall be allocated as follows:

First, to each Middle REMIC Interest corresponding to Loan Group I and Loan Group II in accordance with the respective amounts of principal collections and realized losses with respect to such Mortgage Loans allocated to any Corresponding Class of Master REMIC Certificates for such Middle REMIC Interest.

Second, provided a Group C-B Certificate is still outstanding, to the Class MT1-GSA-CB-1 and Class MT1-GSA-CB-2 Interests, the minimum amount (including deferred interest on the Class MT1-GrpI-II Interest to the extent necessary) to each such that, following such allocations:

(i)

the weighted average of the interest rates of such classes (determined by subjecting the Class MT1-GSA-CB-1 Interest to a floor of 6.444% and the Class MT1-GSA-CB-2 Interest to a cap of 4.0000%) equals the pass-through rate of the Group C-B Certificates for the following Accrual Period; and

(ii)

the aggregate of the principal balances of the Class MT1-GSA-CB-1 and Class MT1-GSA-CB-2 Interests is no greater than 1% of the aggregate of the principal balances of the Class LT1-Grp-I and Class LT1-Grp-II Interests as of such Distribution Date.

The Depositor and the Trustee, upon directions from the Depositor, shall, to the extent consistent with this Agreement, take such actions as may be necessary to ensure that, if this Agreement were deemed to create a security interest in the Mortgage Loans, such security interest would be deemed to be a perfected security interest of first priority under applicable law and will be maintained as such throughout the term of this Agreement.

SECTION 2.02

Acceptance by the Trustee.

(a)

Pursuant to Section 4 of the JPMorgan Custodial Agreement, Section 4 of the LaSalle Custodial Agreement and Section 3 of the U.S. Bank Custodial Agreement, each Custodian agrees to execute and deliver on the Closing Date to the Depositor, the Master Servicer, each Seller, each Servicer, the Trustee and the Trust Administrator a Trust Receipt and Initial Certification with respect to the Initial Mortgage Loans in the form annexed hereto as Exhibit H. Based on its review and examination, and only as to the documents identified in such Trust Receipt and Initial Certification, the Custodian acknowledges that such documents appear regular on their face and relate to such Initial Mortgage Loan. The Custodian 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.

Pursuant to Section 6 of the JPMorgan Custodial Agreement, Section 6 of the LaSalle Custodial Agreement and Section 5 of the U.S. Bank Custodial Agreement, not later than 90 days after the Closing Date, the Custodian shall deliver to the Depositor, the Master Servicer, each Seller and Servicer, the Trustee and the Trust Administrator a Trust Receipt and Final Certification with respect to the Initial Mortgage Loans in the form annexed hereto as Exhibit I, with any applicable exceptions noted thereon.

Based solely upon the Trust Receipt and Initial Certification received from each Custodian, and subject to the provisions of Section 2.01 and any exceptions noted on the exception report described in the next paragraph below, the Trustee acknowledges receipt of the documents referred to in Section 2.01 above and declares that it holds and will hold such documents and the other documents delivered to it constituting the Mortgage File, and that it holds or will hold all such assets and such other assets included in the definition of the Trust Fund in trust for the exclusive use and benefit of all present and future Certificateholders.

If, in the course of such review, the Custodian finds any document constituting a part of a Mortgage File which does not meet the requirements of Section 2.01, the Custodian shall list such as an exception in the Trust Receipt and Final Certification pursuant to Section 6 of the JPMorgan Custodial Agreement, Section 6 of the LaSalle Custodial Agreement and Section 5 of the U.S. Bank Custodial Agreement; provided, however, that the Custodian shall not make any determination as to whether (i) any endorsement is sufficient to transfer all right, title and interest of the party so endorsing, as noteholder or assignee thereof, in and to that Mortgage Note 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 related Seller shall promptly correct or cure such defect within 90 days from the date it was so notified of such defect and, if the related Seller does not correct or cure such defect within such period, the related Seller shall either (a) 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 (b) repurchase such Mortgage Loan within 90 days from the date the related Seller was notified of such defect in writing at the Purchase Price of such Mortgage Loan; or such longer period not to exceed 720 days from the Closing Date if the 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; provided, however, that a Seller shall have no liability for recording any Assignment of Mortgage in favor of the Trustee or for the Custodian’s failure to record such Assignment of Mortgage, and provided, further, that no Seller shall be obligated to repurchase or cure any Mortgage Loan solely as a result of the Custodian’s failure to record such Assignment of Mortgage. The Trust Administrator shall direct each Custodian to deliver to each Rating Agency written notice within 270 days from the Closing Date indicating each Mortgage Loan (a) for which a mortgage or assignment of mortgage required to be recorded hereunder 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 Loan. Such notice shall be delivered every 90 days thereafter until the related Mortgage Loan is returned to the Custodian. Any such substitution pursuant to (a) above or purchase pursuant to (b) above shall not be effected prior to the delivery to the Trustee and the Trust Administrator of the Opinion of Counsel required by Section 2.05 hereof, if any, and any substitution pursuant to (a) above shall not be effected prior to the additional delivery to the Trustee or the Trust Administrator of a Request for Release substantially in the form of Exhibit J. No substitution is permitted to be made in any calendar month after the Determination Date for such month. The Purchase Price for any such Mortgage Loan shall be deposited by the related Seller in the Certificate Account on or prior to the Business Day immediately preceding such 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 J hereto, the Custodian shall release the related Mortgage File to the related 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 related Seller repurchases a Mortgage Loan that is a MERS Mortgage Loan, the related Servicer shall, at the related 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 related 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 related Seller as the beneficial holder of such Mortgage Loan.

The Custodian shall execute and deliver prior to 10:00 a.m. (New York time) on each Subsequent Transfer Date to the Depositor, WMMSC, the Trustee and the Trust Administrator a Subsequent Certification in the form annexed hereto as Exhibit H. 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. Neither the Trustee nor the Custodian shall be under any 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 Custodian shall deliver to the Depositor, WMMSC, the Trustee and the Trust Administrator a Final Certification with respect to the Subsequent Mortgage Loans in the form annexed hereto as Exhibit I 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 Custodian shall list such as an exception in the Final Certification; provided, however that the Custodian shall not make any determination as to whether (i) any endorsement is sufficient to transfer all right, title and interest of the party so endorsing, as noteholder or assignee thereof, in and to that Mortgage Note 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 each 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 Trust Administrator, the Depositor and any Certificateholder against such Seller.

SECTION 2.03

Representations and Warranties of the Sellers, Master Servicer and Servicers.

(a)

Each of DLJMC, in its capacity as a Seller, Xxxxx Fargo, in its capacity as Master Servicer, WMMSC, in its capacity as a Seller and a Servicer, GreenPoint, in its capacity as a Seller and a Servicer, Fairbanks, in its capacity as a Servicer and the Special Servicer, and WFHM, in its capacity as a Servicer, hereby makes the representations and warranties applicable to it set forth in Schedule IIA, IIB, IIC, IID, IIE or IIF, respectively, as applicable, hereto, and by this reference incorporated herein, to the Depositor, the Trustee and the Trust Administrator, as of the Closing Date, or if so specified therein, as of the Cut-off Date or such other date as may be specified. In addition, GreenPoint, Fairbanks and WFHM, in their respective capacities as Servicers, hereby makes the representations and warranties applicable to it set forth in Schedule IID, IIE and IIF hereto, and by this reference incorporated herein, to the Master Servicer, as of the Closing Date, or if so specified therein, as of the Cut-off Date or such other date as may be specified.

(b)

Each of DLJMC, in its capacity as a Seller, GreenPoint, in its capacity as a Seller, and WMMSC, in its capacity as a Seller, hereby make the representations and warranties set forth in Schedule IIIA, IIIB or IIIC, respectively, applicable to the Mortgage Loans and by this reference incorporated herein, to the Depositor, the Trustee and the Trust Administrator, as of the Closing Date, or if so specified therein, as of the Cut-off Date or such other date as may be specified, with respect to the Initial Mortgage Loans identified on Schedule I hereto and as of the related Subsequent Transfer Date with respect to any applicable Subsequent Mortgage Loans identified on Schedule I hereto. Any breach of the representations and warranties set forth in Schedule IIIA(xxiii), IIIA(xxiv), IIIA(xxvi), IIIB(xxiii) and IIIC(xxiii) shall be deemed to materially and adversely affect the interests of the Certificateholders in that Mortgage Loan, notwithstanding the related Seller’s lack of knowledge with respect to the substance of such representation and warranty.

(c)

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. Each 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 interests of the Certificateholders in any Mortgage Loan sold by the related Seller to the Trust, 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 at the Purchase 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 and the Trust Administrator 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 or the Trust Administrator of a Request for Release substantially in the form of Exhibit J relating to the Deleted Mortgage Loan and the Mortgage File for any such Qualified Substitute Mortgage Loan. The related Seller shall promptly reimburse the Trustee, the Trust Administrator and the related Servicer for any actual out-of-pocket expenses reasonably incurred by the Trustee, the Trust Administrator and such related Servicer in respect of enforcing the remedies for such breach. With respect to any representation and warranties described in this Section which are made to the best of a Seller’s knowledge if it is discovered by either the Depositor, the Master Servicer, any Seller, any Servicer, the Special Servicer, the Trustee or the Trust Administrator that the substance of such representation and warranty is inaccurate and such inaccuracy materially and adversely affects the value of the related Mortgage Loan or the interests of the Certificateholders therein, notwithstanding such 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 related Seller shall deliver to the Custodian 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. No substitution is permitted to be made in any calendar month after the Determination Date for such month. Scheduled Payments due with respect to Qualified Substitute Mortgage Loans in the month of substitution shall not be part of the Trust Fund and will be retained by the related Seller on the next succeeding Distribution Date. For the month of substitution, distributions to Certificateholders will include the monthly payment due on any Deleted Mortgage Loan for such month and thereafter the related Seller shall be entitled to retain all amounts received in respect of such Deleted Mortgage Loan. The related Seller shall amend the Mortgage Loan Schedule for the benefit of the Certificateholders to reflect the removal of such Deleted Mortgage Loan and the substitution of the Qualified Substitute Mortgage Loan or Loans and the related Seller shall deliver the amended Mortgage Loan Schedule to the Trustee, the related Servicer and the Trust Administrator. Upon such substitution, the Qualified Substitute Mortgage Loan or Loans shall be subject to the terms of this Agreement in all respects, and the related 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 Collection Account of the amount required to be deposited therein in connection with such substitution as described in the following paragraph, the Trustee shall instruct the Custodian to release the Mortgage File held for the benefit of the Certificateholders relating to such Deleted Mortgage Loan to the related Seller and the Trustee shall execute and deliver at the related Seller’s direction such instruments of transfer or assignment prepared by the related Seller, in each case without recourse, as shall be necessary to vest title in the related 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 a Seller substitutes one or more Qualified Substitute Mortgage Loans for one or more Deleted Mortgage Loans, the related Servicer shall 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 aggregate of any unreimbursed Advances and Servicing Advances and unpaid Servicing Fees with respect to such Deleted Mortgage Loans shall be deposited in the Collection Account by the related Seller on or before the Business Day immediately preceding the Distribution Date in the month succeeding the calendar month during which the related Mortgage Loan became required to be repurchased 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 a Seller shall have repurchased a Mortgage Loan, the Purchase Price therefor shall be deposited in the Collection Account on or before the Business Day immediately preceding the Distribution Date in the month following the month during which the related Seller became obligated hereunder to repurchase or replace such Mortgage Loan and upon such deposit of the Purchase Price, the delivery of the Opinion of Counsel if required by Section 2.05 and receipt of a Request for Release in the form of Exhibit J hereto, the Custodian shall 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, the Trustee or the Trust Administrator 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, the Trust Administrator or the Custodian for the benefit of the Certificateholders.

Notwithstanding the foregoing, the substitution of a Deleted Mortgage Loan that is a WMMSC Serviced Mortgage Loan or the repurchase of a Mortgage Loan that is a WMMSC Serviced Mortgage Loan by a Seller shall be subject to, and shall in no way adversely affect, the right of WMMSC to continue servicing and collecting its Servicing Fee for such Deleted Mortgage Loan or Mortgage Loan, as applicable.

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 the Mortgage Loans 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 Custodian.

SECTION 2.05

Delivery of Opinion of Counsel in Connection with Substitutions.

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 related Seller delivers to the Trustee and the Trust Administrator an Opinion of Counsel, which Opinion of Counsel shall not be at the expense of any of the Trustee, the Trust Administrator or the Trust Fund, addressed to the Trustee and the Trust Administrator, 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.

SECTION 2.06

Issuance of Certificates.

The Trustee acknowledges the assignment to it of the Mortgage Loans together with the assignment to it of all other assets included in the Trust Fund, receipt of which, subject to the provisions of Section 2.02(a), is hereby acknowledged. Concurrently with such assignment and delivery and in exchange therefor, the Trust Administrator, pursuant to the written request of the Depositor executed by an officer of the Depositor, has executed the Certificates and caused them to be authenticated and delivered to or upon the order of the Depositor in authorized denominations which evidence ownership of the Trust Fund. The rights of the Holders of such Certificates to receive distributions from the Trust Fund and all ownership interests of the Holders of the Certificates in such distributions shall be as set forth in this Agreement.

SECTION 2.07

REMIC Provisions.

(a)

The Depositor hereby elects and authorizes the Trust Administrator to treat the Trust Fund as the number of separate REMICs specified in the Preliminary Statement (each, a “REMIC”) under the Code and, if necessary, under applicable state law. Each such election will be made on Form 1066 or other appropriate federal tax or information return (including Form 8811) or any appropriate state return (x) for the taxable year ending on the last day of the calendar year in which the Certificates are issued and (y) for the taxable year ending on the last day of the calendar year in which Certificates are first sold to a third party. The Closing Date is hereby designated as the “startup day” of each REMIC created hereunder within the meaning of Section 860G(a)(9) of the Code. The “regular interests” (within the meaning of Section 860G of the Code) in the Master REMIC shall consist of the Certificates other than the Class AR and Class AR-L Certificates, and the Class AR Certificates shall represent the beneficial ownership of the “residual interest” in Middle REMIC 1, Middle REMIC 2 and the Master REMIC. The Class AR-L Certificates shall represent the beneficial ownership of the “residual interest” in each Subsidiary REMIC. Neither the Depositor nor the Trust Administrator nor the Trustee shall permit the creation of any “interests” (within the meaning of Section 860G of the Code) in any REMIC other than the Certificates, the Subsidiary REMIC Regular Interests and the Middle Tier Interests.

(b)

The Trust Administrator on behalf of the Holders of the Class AR Certificates, shall act as agent for the Class AR Certificateholder as the “tax matters person” (within the meaning of the REMIC Provisions) for Middle REMIC 1, Middle REMIC 2 and the Master REMIC, in the manner provided under Treasury regulations section 1.860F-4(d) and temporary Treasury regulations section 301.6231(a)(7)-1T. By its acceptance of a Class AR Certificate, each Holder thereof shall have agreed to such appointment and shall have consented to the appointment of the Trust Administrator as its agent to act on behalf of Middle REMIC 1, Middle REMIC 2 and the Master REMIC pursuant to the specific duties outlined herein. The Trust Administrator on behalf of the Holders of the Class AR-L Certificates, shall act as agent for the Class AR-L Certificateholder as the “tax matters person” (within the meaning of the REMIC Provisions) for each Subsidiary REMIC, in the manner provided under Treasury regulations section 1.860F-4(d) and temporary Treasury regulations section 301.6231(a)(7)-1T. By its acceptance of a Class AR-L Certificate, each Holder thereof shall have agreed to such appointment and shall have consented to the appointment of the Trust Administrator as its agent to act on behalf of each Subsidiary REMIC pursuant to the specific duties outlined herein.

(c)

A Holder of the Class AR Certificates, by the purchase of such Certificates, shall be deemed to have agreed to timely pay, upon demand by the Trust Administrator, the amount of any minimum California state franchise taxes due with respect to Middle REMIC 1, Middle REMIC 2 and the Master REMIC created hereunder under Sections 23151(a) and 23153(a) of the California Revenue and Taxation Code. Notwithstanding the foregoing, the Trust Administrator shall be authorized to retain the amount of such tax from amounts otherwise distributable to such Holder in the event such Holder does not promptly pay such amount upon demand by the Trust Administrator. In the event that any other federal, state or local tax is imposed, including without limitation taxes imposed on a “prohibited transaction” of Middle REMIC 1, Middle REMIC 2 or the Master REMIC as defined in Section 860F of the Code, such tax shall be charged against amounts otherwise available for distribution to the applicable Holder of a Class AR Certificate and then against amounts otherwise available for distribution to the Holders of Regular Certificates in accordance with the provisions set forth in Section 4.01. The Trust Administrator or the Trustee shall promptly deposit in the Certificate Account any amount of “prohibited transaction” tax that results from a breach of the Trust Administrator’s or the Trustee’s duties, respectively, under this Agreement. The Master Servicer or the related Servicer shall promptly deposit in the Certificate Account any amount of “prohibited transaction” tax that results from a breach of the Master Servicer’s or such Servicer’s duties, respectively, under this Agreement. A Holder of the Class AR-L Certificates, by the purchase of such Certificates, shall be deemed to have agreed to timely pay, upon demand by the Trust Administrator, the amount of any minimum California state franchise taxes due with respect to each Subsidiary REMIC under Sections 23151(a) and 23153(a) of the California Revenue and Taxation Code. Notwithstanding the foregoing, the Trust Administrator shall be authorized to retain the amount of such tax from amounts otherwise distributable to such Holder in the event such Holder does not promptly pay such amount upon demand by the Trust Administrator. In the event that any other federal, state or local tax is imposed, including without limitation taxes imposed on a “prohibited transaction” of a Subsidiary REMIC as defined in Section 860F of the Code, such tax shall be charged against amounts otherwise available for distribution to the applicable Holder of a Class AR-L Certificate and then against amounts otherwise available for distribution on the applicable Subsidiary REMIC Regular Interests in accordance with the provisions set forth in Section 4.01. The Trust Administrator or the Trustee shall promptly deposit in the applicable Subsidiary REMIC any amount of “prohibited transaction” tax that results from a breach of the Trust Administrator’s or the Trustee’s duties, respectively, under this Agreement. The Master Servicer or the related Servicer shall promptly deposit in the Certificate Account any amount of “prohibited transaction” tax that results from a breach of the Master Servicer’s or such Servicer’s duties, respectively, under this Agreement.

(d)

The Trust Administrator shall act as attorney-in-fact and as agent on behalf of the tax matters person of each REMIC created hereunder and in such capacity the Trust Administrator shall: (i) prepare, sign and file, or cause to be prepared, signed and filed, federal and state tax returns using a calendar year as the taxable year for each REMIC created hereunder when and as required by the REMIC Provisions and other applicable federal income tax laws as the direct representative of each such REMIC in compliance with the Code and shall provide copies of such returns as required by the Code; (ii) make an election, on behalf of each REMIC created hereunder, to be treated as a REMIC on the federal tax return of such REMIC for its first taxable year, in accordance with the REMIC Provisions; and (iii) prepare and forward, or cause to be prepared and forwarded, to the Certificateholders and to any governmental taxing authority all information reports as and when required to be provided to them in accordance with the REMIC Provisions. The expenses of preparing and filing such returns shall be borne by the Trust Administrator. The Depositor, the Master Servicer and the related Servicer shall provide on a prompt and timely basis to the Trust Administrator or its designee such information with respect to each REMIC created hereunder as is in their possession and reasonably required or requested by the Trust Administrator to enable it to perform its obligations under this subsection.

In its capacity as attorney-in-fact and as agent on behalf of the tax matters person, the Trust Administrator shall also: (A) act on behalf of each REMIC created hereunder in relation to any tax matter or controversy involving the Trust Fund, (B) represent the Trust Fund in any administrative or judicial proceeding relating to an examination or audit by any governmental taxing authority with respect thereto and (C) cause to be paid solely from the sources provided herein the amount of any taxes imposed on each REMIC created hereunder when and as the same shall be due and payable (but such obligation shall not prevent the Trust Administrator or any other appropriate Person from contesting any such tax in appropriate proceedings and shall not prevent the Trust Administrator from withholding payment of such tax, if permitted by law, pending the outcome of such proceedings).

(e)

The Trust Administrator shall provide (i) to any transferor of a Residual Certificate such information as is necessary for the application of any tax relating to the transfer of such Residual Certificate to any Person who is not a permitted transferee, (ii) to the Certificateholders such information or reports as are required by the Code or the REMIC Provisions including reports relating to interest, original issue discount and market discount or premium and (iii) to the Internal Revenue Service the name, title, address and telephone number of the person who will serve as the representative of each REMIC created hereunder.

(f)

The Trustee, to the extent directed by the Trust Administrator, the Depositor, the Holder of the Class AR Certificates (with respect to Middle REMIC 1, Middle REMIC 2 and the Master REMIC) and the Holder of the Class AR-L Certificates (with respect to each Subsidiary REMIC) shall take any action or cause the Trust Fund to take any action necessary to create or maintain the status of each REMIC created hereunder as a REMIC under the REMIC Provisions and shall assist each other as necessary to create or maintain such status. Neither the Trustee, to the extent directed or (in the case of a failure to act) not directed by the Trust Administrator, nor the Holders of the Residual Certificates shall take any action, cause the Trust Fund to take any action or fail to take (or fail to cause the Trust Fund to take) any action that, under the REMIC Provisions, if taken or not taken, as the case may be, could (i) endanger the status of each REMIC created hereunder as a REMIC or (ii) result in the imposition of a tax upon a 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 in Section 860G(d) of the Code) (either such event, an “Adverse REMIC Event”) unless the Trustee and the Trust Administrator 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.

The Trustee and the Trust Administrator shall not take or fail to take any action (whether or not authorized hereunder) as to which the Master Servicer, a Servicer or the Depositor has advised it in writing that it has received an Opinion of Counsel to the effect that an Adverse REMIC Event could occur with respect to such action. In addition, prior to taking any action with respect to a REMIC or their assets, or causing any REMIC created hereunder to take any action, which is not expressly permitted under the terms of this Agreement, the Trustee and the Trust Administrator will consult with the Master Servicer, the Servicers and the Depositor or their designees, in writing, with respect to whether such action could cause an Adverse REMIC Event to occur with respect to any REMIC created hereunder and the Trustee and the Trust Administrator shall not take any such action or cause that REMIC to take any such action as to which the Master Servicer, any Servicer or the Depositor has advised it in writing that an Adverse REMIC Event could occur.

In addition, prior to taking any action with respect to any REMIC created hereunder or the assets therein, or causing any REMIC created hereunder to take any action, which is not expressly permitted under the terms of this Agreement, the Holders of the Residual Certificates will consult with the Trust Administrator or its designee, in writing, with respect to whether such action could cause an Adverse REMIC Event to occur with respect to any REMIC created hereunder, and no such Person shall take any action or cause the Trust Fund to take any such action as to which the Trust Administrator has advised it in writing that an Adverse REMIC Event could occur. The Trust Administrator may consult with counsel to make such written advice, and the cost of same shall be borne by the party seeking to take action not permitted by this Agreement.

At all times as may be required by the Code, the Trust Administrator will to the extent within its control and the scope of its duties more specifically set forth herein, maintain substantially all of the assets of the REMICs as “qualified mortgages” as defined in Section 860G(a)(3) of the Code and “permitted investments” as defined in Section 860G(a)(5) of the Code.

In the event that any tax is imposed on “prohibited transactions” of any REMIC created hereunder, as defined in Section 860F(a)(2) of the Code, on “net income from foreclosure property” of such REMIC, as defined in Section 860G(c) of the Code, on any contributions to a REMIC after the Startup Day therefor pursuant to Section 860G(d) of the Code, or any other tax is imposed by the Code or any applicable provisions of state or local tax laws, such tax shall be charged (i) to the related Servicer, if such Servicer has in its sole discretion determined to indemnify the Trust Fund against such tax or if such tax arises out of or results from a breach of such Servicer’s duties under (x) Section 2.07(j) of this Agreement to not enter into any arrangement by which a REMIC would receive a fee or other compensation for services or to permit such REMIC to receive any income from assets other than “qualified mortgages” or “permitted investments”, (y) Section 3.01 of this Agreement to not make or any modification, waiver or amendment of any Mortgage Loan which would cause any REMIC created 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 or (z) Section 3.11(d) of this Agreement to not cause any REO Property to fail to qualify as “foreclosure property” within the meaning of Section 860G(a)(8) of the Code or to subject any REMIC created 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 of otherwise, (ii) to the Master Servicer, if such tax arises out of or results from a breach by the Master Servicer of any of its obligations under this Agreement or if the Master Servicer has in its sole discretion determined to indemnify the Trust Fund against such tax, (iii) to the Trust Administrator, if such tax arises out of or results from a breach by the Trust Administrator of any of its obligations under this Article II, (iv) to the Trustee, if such tax arises out of or results from a breach by the Trustee of any of its obligations under this Article II, or (v) otherwise against amounts on deposit in the Collection Account as provided by Section 3.08 and on the Distribution Date(s) following such reimbursement the aggregate of such taxes shall be allocated in reduction of the Interest Distribution Amount on each Class entitled thereto in the same manner as if such taxes constituted a Prepayment Interest Shortfall.

In accordance with Section 2.07(c), the related Servicer, the Master Servicer, the Trust Administrator or the Trustee, as applicable, shall promptly deposit in the Certificate Account any amount of such tax.

For purposes of this Section 2.07(g), a tax is imposed following the final and unappealable determination under the Code of the amount of such tax and written notice thereof by the Tax Matters Person to the party to be charged.

The failure of the related Servicer to promptly deposit in the Certificate Account any amount of such tax shall be an Event of Default, as provided in Section 8.01(b). However, in the case of WMMSC, the prompt deposit of any such amount in the Certificate Account shall cure any Special Event of Default unless notice of such Special Event of Default is accompanied by an Opinion of Counsel, at the expense of WMMSC, to the effect that the cumulative effect of WMMSC’s breach or breaches, notwithstanding the deposit of the amounts of any such tax, shall have given rise to a substantial risk that any REMIC created hereunder would fail to continue to qualify as a REMIC.

(h)

The Trust Administrator 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 or as otherwise may be required by the REMIC Provisions.

(i)

Following the Startup Day, none of any Servicer, the Trustee (which will act only at the direction of the Trust Administrator or as otherwise specifically provided in this Agreement) or the Trust Administrator shall accept any contributions of assets to any REMIC created hereunder unless (subject to Section 2.05) such Servicer, the Trustee or the Trust Administrator shall have received an Opinion of Counsel (at the expense of the party seeking to make such contribution) to the effect that the inclusion of such assets in a REMIC will not cause that REMIC to fail to qualify as a REMIC at any time that any Certificates are outstanding, or subject that REMIC to any tax under the REMIC Provisions or other applicable provisions of federal, state and local law or ordinances.

(j)

None of any Servicer, the Trustee (which will act only at the direction of the Trust Administrator or as otherwise specifically provided in this Agreement) or the Trust Administrator shall (subject to Section 2.05) enter into any arrangement by which a REMIC will receive a fee or other compensation for services nor permit such REMIC to receive any income from assets other than “qualified mortgages” as defined in Section 860G(a)(3) of the Code or “permitted investments” as defined in Section 860G(a)(5) of the Code.

(k)

Within 30 days after the Closing Date, the Trust Administrator shall apply to the Internal Revenue Service for an employer identification number for each REMIC created hereunder by means of a Form SS-4 or other acceptable means and prepare and file with the Internal Revenue Service Form 8811, “Information Return for Real Estate Mortgage Investment Conduits (REMIC) and Issuers of Collateralized Debt Obligations” for each REMIC.

(l)

None of the Trustee (which will act only at the direction of the Trust Administrator or as otherwise specifically provided in this Agreement), the Trust Administrator, the Master Servicer or any Servicer shall sell, dispose of or substitute for any of the Mortgage Loans (except in connection with (i) the default, imminent default or foreclosure of a Mortgage Loan, including but not limited to, the acquisition or sale of a Mortgaged Property acquired by deed in lieu of foreclosure, (ii) the bankruptcy of any REMIC created hereunder, (iii) the termination of any REMIC created hereunder pursuant to Article X of this Agreement or (iv) a purchase of Mortgage Loans pursuant to Article II or III of this Agreement) nor acquire any assets for a REMIC, nor sell or dispose of any investments in the Collection Account or the Certificate Account for gain nor accept any contributions to a REMIC after the Closing Date (a) unless it has received an Opinion of Counsel that such sale, disposition, substitution or acquisition will not affect adversely the status of any REMIC created hereunder as a REMIC or (b) unless the Master Servicer or such Servicer has determined in its sole discretion to indemnify the Trust Fund against such tax.

(m)

In order to enable the Trust Administrator to perform its duties as set forth herein, the Depositor shall provide, or cause to be provided to the Trust Administrator, within ten days after the Closing Date, all information or data that the Trust Administrator 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 and the Trust Administrator shall be entitled to rely upon any and all such information and data in the performance of its duties set forth herein Thereafter, the Master Servicer, or with respect to the WMMSC Serviced Mortgage Loans, WMMSC shall provide, promptly upon request therefor, any such additional information or data (or with respect to WMMSC, any such additional loan level information and data regarding the WMMSC Mortgage Loans) that the Trustee or the Trust Administrator may from time to time reasonably request in order to enable the Trustee and the Trust Administrator to perform their duties as set forth herein and the Trustee and the Trust Administrator shall be entitled to rely upon any and all such information and data in the performance of its duties set forth herein. DLJMC shall indemnify the Trust Administrator and hold it harmless for any loss, liability, damage, claim or expense of the Trust Administrator arising from any failure of the Depositor to provide, or to cause to be provided, accurate information or data to the Trust Administrator on a timely basis. The Master Servicer shall indemnify the Trustee and the Trust Administrator and hold it harmless for any loss, liability, damage, claim or expense of the Trustee and the Trust Administrator arising from any failure of the Master Servicer to provide, or to cause to be provided, accurate information or data required to be provided by the Master Servicer to the Trustee and the Trust Administrator on a timely basis; provided, however, that if any Servicer (other than WMMSC) shall fail to provide such information to the Master Servicer upon timely request for such information by the Master Servicer, that Servicer shall indemnify the Master Servicer, the Trustee and the Trust Administrator and hold it harmless for any loss, liability, damage, claim or expense of the Master Servicer, the Trustee and the Trust Administrator arising from any failure of that Servicer to provide, or to cause to be provided, the information referred to above on a timely basis. WMMSC shall indemnify the Trustee and the Trust Administrator and hold each of them harmless for any loss, liability, damage, claim or expense, other than any special, indirect, punitive or consequential loss, liability, damage, claim or expense, of the Trustee and the Trust Administrator arising from any failure of WMMSC to provide, or to cause to be provided, the loan level information or data regarding the WMMSC Mortgage Loans reasonably requested by the Trustee or Trust Administrator, and required to be provided by WMMSC pursuant to this Section 2.07(m), on a timely basis. The indemnification provisions hereunder shall survive the termination of this Agreement and shall extend to any co-trustee and co-trust administrator appointed pursuant to this Agreement.

SECTION 2.08

Covenants of the Master Servicer and each Servicer.

The Master Servicer and each Servicer, severally and not jointly, hereby covenants to the Depositor, the Trustee and the Trust Administrator as follows:

(a)

Such Servicer or the Master Servicer shall comply in the performance of its obligations under this Agreement with all reasonable rules and requirements of the insurer under each Mortgage Guaranty Insurance Policy; and

(b)

ARTICLE III

ADMINISTRATION AND SERVICING

OF MORTGAGE LOANS

SECTION 3.01

Master Servicing and Servicing of Mortgage Loans.

For and on behalf of the Certificateholders, as independent contractors of the Trustee, (i) each Servicer, severally and not jointly, shall service and administer the related Non-Designated Mortgage Loans in accordance with the terms of this Agreement and with Accepted Servicing Practices, (ii) the Master Servicer shall, in accordance with Section 3.03 of this Agreement, master service and adminster the Non-Designated Mortgage Loans (other than the WMMSC Serviced Mortgage Loans) by overseeing and enforcing the servicing of the Non-Designated Mortgage Loans by the related Servicer (other than WMMSC) according to the terms of this Agreement and (iii) the Master Servicer shall, in accordance with the Section 3.20 of this Agreement, master service and administer the Designated Mortgage Loans by overseeing and enforcing the servicing of the Designated Mortgage Loans by the related Designated Servicer according to the terms of the related Designated Servicing Agreement. The obligations of each of Fairbanks, GreenPoint, WFHM and WMMSC hereunder to service and administer the Mortgage Loans shall be limited to the Fairbanks Serviced Mortgage Loans, GreenPoint Serviced Mortgage Loans, WFHM Serviced Mortgage Loans and WMMSC Serviced Mortgage Loans, respectively; and with respect to the duties and obligations of each Servicer, references herein to related “Mortgage Loans” shall be limited to the Fairbanks Serviced Mortgage Loans (and the related proceeds thereof and related REO Properties) in the case of Fairbanks, the GreenPoint Serviced Mortgage Loans (and the related proceeds thereof and related REO Properties) in the case of GreenPoint, the WFHM Serviced Mortgage Loans (and the related proceeds thereof and related REO Properties) in the case of WFHM and the WMMSC Serviced Mortgage Loans (and the related proceeds thereof and related REO Properties) in the case of WMMSC; and in no event shall any Servicer have any responsibility or liability with respect to any of the other Mortgage Loans. The obligations of the Master Servicer to master service and administer the Mortgage Loans shall be limited to the Fairbanks Serviced Mortgage Loans, the GreenPoint Serviced Mortgage Loans, the WFHM Serviced Mortgage Loans and the Designated Mortgage Loans. Notwithstanding anything to the contrary contained in this Agreement, the Master Servicer shall have no obligations to master service or administer the WMMSC Serviced Mortgage Loans. In connection with such servicing and administration of the Non-Designated Mortgage Loans, the Master Servicer and each Servicer shall have full power and authority, acting alone and/or, with respect to any Servicer, 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 and other Liquidation Proceeds, and (iv) to effectuate foreclosure or other conversion of the ownership of the Mortgaged Property securing any Mortgage Loan; provided that neither the Master Servicer nor any Servicer shall 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, the Trust Administrator or the Certificateholders under this Agreement. The Master Servicer and each 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 created 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 Master Servicer and each Servicer, in its own name or in the name of the Depositor and the Trustee, is hereby authorized and empowered by the Depositor, the Trustee and the Trust Administrator, when the Master Servicer or such Servicer believes it appropriate in its reasonable judgment, to execute and deliver, on behalf of the Trustee, the Trust Administrator, 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 the Mortgage Loans, and with respect to the Mortgaged Properties held for the benefit of the Certificateholders. The Master Servicer and each Servicer shall prepare and deliver to the Depositor and/or the Trustee and/or the Trust Administrator such documents requiring execution and delivery by either or both of them as are necessary or appropriate to enable the Master Servicer or such Servicer to master servicer and administer or service and administer the Mortgage Loans, as applicable, to the extent that the Master Servicer or such 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 or the Trust Administrator shall execute such documents and deliver them to the Master Servicer or such Servicer, as applicable.

In accordance with the standards of the preceding paragraph and unless determined in good faith to be a Nonrecoverable Advance, each 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 related to Non-Designated Mortgage Loans, which advances 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 3.08. In no event will any Servicer be required to make any Servicing Advance that would constitute a Nonrecoverable Advance. The costs incurred by a Servicer, if any, in effecting the timely payments of taxes and assessments on the Mortgaged Properties related to Non-Designated Mortgage Loans 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 Non-Designated Mortgage Loans, notwithstanding that the terms of such Non-Designated Mortgage Loans so permit.

Each Servicer hereby acknowledges that, to the extent such Servicer has previously serviced some or all of the Non-Designated Mortgage Loans pursuant to another servicing agreement, the provisions contained in this Agreement shall supersede the provisions contained in such other servicing agreement from and after the Closing Date. In addition, the Master Servicer hereby acknowledges that, to the extent the Master Servicer or either Designated Servicer has previously serviced some or all of the Designated Mortgage Loans pursuant to another servicing agreement, the provisions contained in the related Designated Servicing Agreement shall supersede the provisions contained in such other servicing agreement from and after the Closing Date.

Notwithstanding anything in this Agreement to the contrary, the purchase of any WMMSC Serviced Mortgage Loan by any Person shall be subject to the rights of WMMSC to continue servicing such WMMSC Serviced Mortgage Loan for the same Servicing Fee substantially in accordance with the terms of this Agreement.

The related Servicer, other than WMMSC, will fully furnish, in accordance with the Fair Credit Reporting Act and its implementing regulations, accurate and complete information (e.g., favorable and unfavorable) on its borrower credit files to Equifax, Experian and Trans Union Credit Information Company, on a monthly basis.

With respect to each WMMSC Serviced Mortgage Loan, WMMSC will furnish information regarding its borrower credit files to credit reporting agencies in compliance with the provisions of the Fair Credit Reporting Act and its implementing regulations applicable to WMMSC.

Each Servicer is authorized and empowered, on behalf of the Certificateholders and the Trustee, in its own name or in the name of any Subservicer, when a Servicer or any Subservicer, as the case may be, believes it appropriate in its best judgment to register any related Mortgage Loan on the MERS® System, or cause the removal from the registration of such 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 Non-Designated Mortgage Loans may be subserviced by a Subservicer on behalf of the related 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. With respect to the Non-Designated Mortgage Loans, each 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 such Servicer of the Subservicer shall not release such Servicer from any of its obligations hereunder and such Servicer shall remain responsible hereunder for all acts and omissions of the Subservicer as fully as if such acts and omissions were those of such Servicer. With respect to the Non-Designated Mortgage Loans, each Servicer shall pay all fees and expenses of any Subservicer engaged by such Servicer from its own funds.

Notwithstanding the foregoing, with respect to the Non-Designated Mortgage Loans, each 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 such Servicer’s obligation to perform all or substantially all of the servicing of the related Non-Designated Mortgage Loans to such Outsourcer. In such event, the use by a Servicer of any such Outsourcer shall not release the related Servicer from any of its obligations hereunder and such Servicer shall remain responsible hereunder for all acts and omissions of such Outsourcer as fully as if such acts and omissions were those of such Servicer, and such Servicer shall pay all fees and expenses of the Outsourcer from such Servicer’s own funds. Each Servicer may in connection with its duties as Servicer hereunder enter into transactions with any of its Affiliates relating to the Mortgage Loans; provided that (a) such Servicer acts (i) in accordance with Accepted Servicing Practices and the terms of this Agreement, and (ii) in the ordinary course of business of such Servicer; and (b) the terms of such transaction are no less favorable to such Servicer than it would obtain in a comparable arm’s-length transaction with a Person that is not an Affiliate of such Servicer.

(b)

With respect to any Non-Designated Mortgage Loans, at the cost and expense of a Servicer, without any right of reimbursement from the Depositor, the Trustee, the Trust Administrator or the applicable Collection Account, such 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 such Servicer, at such Servicer’s option, from electing to service the related Non-Designated Mortgage Loans itself. In the event that a Servicer’s responsibilities and duties under this Agreement are terminated pursuant to Section 8.01, and if requested to do so by the Trustee or Trust Administrator, such Servicer shall, at its own cost and expense terminate the rights and responsibilities of its Subservicer as soon as is reasonably possible. Each Servicer shall pay all fees, expenses or penalties necessary in order to terminate the rights and responsibilities of its Subservicer from such Servicer’s own funds without any right of reimbursement from the Depositor, Trustee, Trust Administrator, or the applicable Collection Account.

(c)

Notwithstanding any of the provisions of this Agreement relating to agreements or arrangements between a Servicer and its Subservicer, or a Servicer and its Outsourcer, or any reference herein to actions taken through the Subservicer, the Outsourcer, or otherwise, the related Servicer shall not be relieved of its obligations to the Depositor, Trustee, the Trust Administrator 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 related Non-Designated Mortgage Loans. Each Servicer shall be entitled to enter into an agreement with its Subservicer and Outsourcer for indemnification of such Servicer or Outsourcer, as applicable, by such Subservicer and nothing contained in this Agreement shall be deemed to limit or modify such indemnification.

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

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

(d)

Fairbanks is hereby authorized to enter into a financing or other facility (any such arrangement, a “Facility”) under which (i) Fairbanks assigns or pledges to another person (a “Lender”) (A) Fairbanks’ rights under this Agreement to be reimbursed for any Advances or Servicing Advances, and (B) any and all rights of Fairbanks under this Agreement resulting from Fairbanks’ performance of its obligations under this Agreement, including, without limitation, any Servicing Fees, Special Servicing Fees, interest income, Ancillary Income, and other payments received by Fairbanks for servicing the Fairbanks Serviced Mortgage Loans or Special Serviced Mortgage Loans and (ii) the Lender agrees to fund some or all Advances and/or Servicing Advances required to be made by Fairbanks pursuant to this Agreement. No consent of the Trustee, Trust Administrator, Certificateholders or any other party is required before Fairbanks may enter into a Facility; provided, however, that the consent of the Trust Administrator shall be required before Fairbanks may cause to be outstanding at one time more than one Facility. Notwithstanding the existence of any Facility, Fairbanks shall remain obligated pursuant to this Agreement to make Advances and Servicing Advances pursuant to and as required by this Agreement, and to perform all duties and obligations of Fairbanks under this Agreement and shall not be relieved of such obligations by virtue of such Facility.

SECTION 3.03

Master Servicing by Master Servicer of GreenPoint Serviced Mortgage Loans, Fairbanks Serviced Mortgage Loans and WFHM Serviced Mortgage Loans

For and on behalf of the Certificateholders, the Master Servicer shall oversee and enforce the obligation of GreenPoint, Fairbanks and WFHM to service and administer the GreenPoint Serviced Mortgage Loans, Fairbanks Serviced Mortgage Loans and WFHM Serviced Mortgage Loans, respectively, in accordance with the terms of this Agreement and shall have full power and authority to do any and all things which it may deem necessary or desirable in connection with such master servicing and administration. In performing its obligations hereunder, the Master Servicer shall act in a manner consistent with this Agreement and with customary and usual standards of practice of prudent mortgage loan master servicers. Furthermore, the Master Servicer shall oversee and consult with GreenPoint, Fairbanks and WFHM as necessary from time-to-time to carry out the Master Servicer’s obligations hereunder, shall receive, review and evaluate all reports, information and other data provided to the Master Servicer by GreenPoint, Fairbanks and WFHM and shall cause each of GreenPoint, Fairbanks and WFHM to perform and observe the covenants, obligations and conditions to be performed or observed by such Servicer under this Agreement.

With respect to any Distribution Date, no later than the related Cash Remittance Date, the Master Servicer shall remit to the Trust Administrator for deposit in the Certificate Account the amount of the Compensating Interest Payment for the Master Servicer, with respect to the GreenPoint Serviced Mortgage Loans, the Fairbanks Servicved Mortgage Loans, the WFHM Serviced Mortgage Loans and the Designated Mortgage Loans, for the related Prepayment Period. The aggregate of such deposits shall be made from the Master Servicer’s own funds, without reimbursement therefor.

SECTION 3.04

Trustee to Act as Master Servicer or Servicer.

In the event that (A) the Master Servicer shall for any reason no longer be Master Servicer hereunder or (B) any Servicer shall for any reason no longer be a Servicer hereunder and, with respect to any Servicer other than WMMSC, the Master Servicer shall for any reason no longer be Master Servicer hereunder (including, in each case, by reason of an Event of Default), the Trustee or its successor shall thereupon assume all of the rights and obligations of the Master Servicer or such Servicer hereunder arising thereafter (except that the Trustee shall not be (i) liable for losses of the Master Servicer or such Servicer pursuant to Section 3.09 hereof or any acts or omissions of the related predecessor of the Master Servicer or such 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 Master Servicer or such Servicer hereunder). Any such assumption shall be subject to Section 8.02 hereof.

Each Servicer shall, upon request of the Trust Administrator, but at the expense of such 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 such 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 Subservicing Agreement or substitute Subservicing Agreement to the assuming party.

SECTION 3.05

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

(a)

Continuously from the date hereof until the principal and interest on all Non-Designated Mortgage Loans have been paid in full or such Non-Designated Mortgage Loans have become Liquidated Mortgage Loans, each Servicer shall proceed in accordance with Accepted Servicing Practices to collect all payments due under each of the related Non-Designated Mortgage Loans when the same shall become due and payable to the extent consistent with this Agreement and the terms and provisions of any related Mortgage Guaranty Insurance Policy and shall take special care with respect to Non-Designated Mortgage Loans for which a Servicer collects escrow payments in ascertaining and estimating Escrow Payments and all other charges that will become due and payable with respect to the Non-Designated Mortgage Loans and the related Mortgaged Properties, to the end that the installments payable by the related Mortgagors will be sufficient to pay such charges as and when they become due and payable. Consistent with the foregoing, in connection with Non-Designated Mortgage Loans which it is directly servicing, each Servicer may in its discretion (i) waive any late payment charge or any prepayment charge or penalty interest in connection with the prepayment of a Mortgage Loan and (ii) extend the Due Dates for payments due on a Mortgage Note for a period not greater than 180 days; provided, however, that no such Servicer can extend the maturity of any such Non-Designated 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 related Servicer shall make Advances on the related Non-Designated Mortgage Loans in accordance with the provisions of Section 5.01 during the scheduled period in accordance with the amortization schedule of such Mortgage Loan without modification thereof by reason of such arrangements. No Servicer shall 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)

Each Servicer shall segregate and hold all funds collected and received pursuant to a Non-Designated Mortgage Loan 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], in trust for the Holders of Credit Suisse First Boston Mortgage Securities Corp., CSFB Mortgage-Backed Pass-Through Certificates, Series 2004-3” or, if established and maintained by a Subservicer on behalf of a Servicer, “[Subservicer’s name], in trust for [Servicer’s name]” or “[Subservicer’s name], as agent, trustee and/or bailee of principal and interest custodial account for [Servicer’s name], its successors and assigns, for various owners of interest in [Servicer’s name] mortgage-backed pools. In the event that a Subservicer employs a subservicer, the Collection Account shall be titled “[name of Subservicer’s subservicer], in trust for [Subservicer’s name].” Each Collection Account shall be an Eligible Account acceptable to the Depositor and the Trust Administrator. Funds deposited in a Collection Account may be drawn on by the related Servicer in accordance with Section 3.08. Any funds deposited in a Collection Account (other than an account established by WMMSC) shall either be invested in Eligible Investments or at all times be fully insured to the full extent permitted under applicable law. Notwithstanding the foregoing, one of the Collection Accounts established by WMMSC shall be an Investment Account.

(c)

Each Servicer shall deposit in the applicable Collection Account on a daily basis within two (2) Business Days of receipt, and retain therein, the following collections remitted by Subservicers or payments received by such Servicer and payments made by such Servicer subsequent to the Cut-off Date, other than payments of principal and interest due on or before the Cut-off Date:

(i)

all payments on account of principal on the related Non-Designated Mortgage Loans, including all Principal Prepayments;

(ii)

all payments on account of interest on the related Non-Designated Mortgage Loans;

(iii)

all Liquidation Proceeds on the related Non-Designated Mortgage Loans;

(iv)

all Insurance Proceeds on the related Non-Designated Mortgage Loans including amounts required to be deposited pursuant to Section 3.09 (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 3.09);

(v)

all Advances made by such Servicer pursuant to Section 5.01;

(vi)

no later than the withdrawal from the Collection Account pursuant to Section 3.08(a)(viii) each month, the applicable amount of the Compensating Interest Payment for such Servicer for the related Prepayment Period. The aggregate of such deposits shall be made from such Servicer’s own funds, without reimbursement therefor.

(vii)

any amounts required to be deposited by such Servicer in respect of net monthly income from REO Property related to any Non-Designated Mortgage Loans pursuant to Section 3.11;

(viii)

[reserved]; and

(ix)

any other amounts required to be deposited hereunder.

The foregoing requirements for deposit into each Collection Account shall be exclusive, it being understood and agreed that, without limiting the generality of the foregoing, with respect to the Non-Designated Mortgage Loans, Ancillary Income need not be deposited by such Servicer into such Collection Account. In addition, notwithstanding the provisions of this Section 3.05, each Servicer may deduct from amounts received by it, prior to deposit into the applicable Collection Account, any portion of any Scheduled Payment representing (i) the applicable Servicing Fee and (ii) with respect to each Non-Designated Mortgage Loan covered by a Lender Paid Mortgage Guaranty Insurance Policy, any amounts required to effect timely payment of the premiums on such Mortgage Guaranty Insurance Policy pursuant to Section 3.09(c). In the event that a 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. Each 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 3.08(a).

(d)

On or prior to the Closing Date, the Trust Administrator shall establish and maintain, on behalf of the Certificateholders, the Certificate Account. The Trust Administrator shall, promptly upon receipt, deposit in the Certificate Account and retain therein the following:

(i)

(a) the aggregate amount remitted by each Servicer of Non-Designated Mortgage Loans to the Trust Administrator pursuant to Section 3.08(a)(viii) and (b) the aggregate amount remitted by each Designated Servicer to the Master Servicer or Trust Administrator pursuant to the related Designated Servicing Agreement;

(ii)

Such direction may be accomplished by delivering an Officer’s Certificate to the Trust Administrator that describes the amounts deposited in error in the Certificate Account. All funds deposited in the Certificate Account shall be held by the Trust Administrator in trust for the Certificateholders until disbursed in accordance with this Agreement or withdrawn in accordance with Section 3.08(b). In no event shall the Trust Administrator incur liability for withdrawals from the Certificate Account at the direction of the Master Servicer or any Servicer.

(e)

Each institution at which a Collection Account, the Certificate Account or the Prefunding Account is maintained shall either hold such funds on deposit uninvested or shall invest the funds therein as directed in writing by the related Servicer, the Trust Administrator or the Depositor, respectively, in Eligible Investments, which shall mature not later than (i) in the case of a Collection Account, the Cash Remittance Date, (ii) in the case of the Certificate Account, the Business Day immediately preceding the Distribution Date, or on the Distribution Date, with respect to Eligible Investments invested with an affiliate of the Trust Administrator, and (iii) in the case of the Prefunding Account, the Business Day immediately preceding a Subsequent Transfer Date, and, in each case, shall not be sold or disposed of prior to its maturity.

On each Subsequent Transfer Date, upon satisfaction of the conditions for such Subsequent Transfer Date set forth in Sections 2.01(d) and (e), with respect to the related Subsequent Transfer Agreement, the Trust Administrator shall remit to the Depositor the applicable Aggregate Subsequent Transfer Amount as payment of the purchase price for the related Subsequent Mortgage Loans.

If any funds remain in the Prefunding Account on June 1, 2004, to the extent that they represent earnings on the amounts originally deposited into the Prefunding Account, the Trust Administrator 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 June 2004 Distribution Date.

(h)

The Trust Administrator shall establish and maintain, on behalf of the Certificateholders, the Capitalized Interest Account. On the Closing Date the Depositor shall remit the Capitalized Interest Deposit to the Trust Administrator for deposit in the Capitalized Interest Account. On the Business Day prior to each of the May 2004 and June 2004 Distribution Dates, the Trust Administrator shall transfer from the Capitalized Interest Account to the Certificate Account an amount equal to the Capitalized Interest Requirement for such Distribution Date. On any Subsequent Transfer Date, any Overfunded Interest Amount shall be withdrawn from the Capitalized Interest Account and paid to the Depositor. Any funds remaining in the Capitalized Interest Account immediately after the termination of the Prefunding Period shall be paid to the Depositor.

To the extent required by the related Mortgage Note and not violative of applicable law, the applicable Servicer shall segregate and hold all funds collected and received pursuant to a Non-Designated Mortgage Loan constituting Escrow Payments separate and apart from any of its own funds and general assets and shall establish and maintain one or more Escrow Accounts, in the form of time deposit or demand accounts, titled, in the case of Servicers “Credit Suisse First Boston Mortgage Securities Corp., CSFB Mortgage-Backed Pass-Through Certificates, Series 2004-3” or, if established and maintained by a Subservicer on behalf of the a Servicer, “[Subservicer’s name], in trust for [Servicer’s name]” or “[Subservicer’s name], as agent, trustee and/or bailee of taxes and insurance custodial account for [Servicer’s name], its successors and assigns, for various owners of interest in [Servicer’s name] mortgage-backed pools. In the event that a Subservicer employs a subservicer, the Escrow Accounts shall be titled “[name of Subservicer’s subservicer] in trust for [Subservicer’s name]. The Escrow Accounts shall be Eligible Accounts. Funds deposited in the Escrow Account may be drawn on by the related Servicer in accordance with Section 3.06(d).

(c)

Each Servicer shall make withdrawals from the Escrow Account only to effect such payments as are required under this Agreement, as set forth in Section 3.06(d). Each Servicer shall be entitled to retain any interest paid on funds deposited in the related Escrow Account by the depository institution, other than interest on escrowed funds required by law to be paid to the Mortgagor.

(d)

Withdrawals from the Escrow Account or Accounts may be made or caused to be made by related Servicer only:

(i)

With respect to each Non-Designated Mortgage Loan, the applicable Servicer shall maintain accurate records reflecting the status of ground rents and taxes and any other item which may become a lien senior to the lien of the related Mortgage and the status of Mortgage Guaranty Insurance Policy premiums, and fire and hazard insurance coverage and shall obtain, from time to time, all bills for the payment of such charges (including renewal premiums) and shall effect or cause to be effected payment thereof prior to the applicable penalty or termination date.

SECTION 3.07

(a)

The Master Servicer and each Servicer shall afford the Depositor, the Trustee and the Trust Administrator reasonable access to all records and documentation regarding the Non-Designated Mortgage Loans and all accounts, insurance information and other matters relating to this Agreement, such access being afforded without charge, but only upon reasonable written request and during normal business hours at the office designated by the Master Servicer or such Servicer. In addition, each Servicer, other than WMMSC, shall afford the Master Servicer reasonable access to all records and documentation regarding the Mortgage Loans and all accounts, insurance information and other matters relating to this Agreement, such access being afforded without charge, but only upon reasonable written request and during normal business hours at the office designated by such Servicer.

Each Servicer shall keep a written or electronic report of each such inspection.

SECTION 3.08

Permitted Withdrawals from the Collection Accounts and Certificate Account.

(a)

Each Servicer may from time to time make withdrawals from the related Collection Account for the following purposes:

(i)

to pay to such Servicer (to the extent not previously retained by such Servicer) the servicing compensation to which it is entitled pursuant to Section 3.14, and to pay to such Servicer, as additional servicing compensation, earnings on or investment income with respect to funds in or credited to such Collection Account;

Each Servicer shall keep and maintain separate accounting, on a Mortgage Loan by Mortgage Loan basis, for the purpose of justifying any withdrawal from the related Collection Account pursuant to such subclauses (i), (ii), (iv) and (v). Prior to making any withdrawal from a Collection Account pursuant to subclause (iii) of a Nonrecoverable Advance, the related Servicer shall deliver to the Trust Administrator a certificate of a Servicing Officer indicating the amount of any previous Advance or Servicing Advance determined by such Servicer to be a Nonrecoverable Advance and identifying the related Non-Designated Mortgage Loans(s), and their respective portions of such Nonrecoverable Advance. In connection with the payment of a Purchase Price, if a Servicer is not required to remit unreimbursed Servicing Advances as specified in the definition of Purchase Price, such Servicer shall be deemed to have been reimbursed for such amount.

(b)

The Trust Administrator shall withdraw funds from the Certificate Account for distributions to Certificateholders in the manner specified in this Agreement (and to withhold from the amounts so withdrawn, the amount of any taxes that it is authorized to withhold pursuant to Section 2.07).

SECTION 3.09

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

(a)

Each Servicer shall cause to be maintained for each related Non-Designated Mortgage Loan hazard insurance such that all buildings upon the related Mortgaged Property are insured by a generally acceptable insurer rated either: “V” or better in the current Best’s Key Rating Guide (“Best’s”) or acceptable to FNMA or FHLMC against loss by fire, hazards of extended coverage and such other hazards as are customary in the area where the related Mortgaged Property is located, in an amount which is at least equal to the lesser of (i) the replacement value of the improvements securing such Non-Designated Mortgage Loan and (ii) the greater of (A) the outstanding principal balance of the Non-Designated 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 Non-Designated Mortgage Loan, the related Mortgaged Property was located in an area identified in the Federal Register by the Federal Emergency Management Agency as having special flood hazards (and such flood insurance has been made available), the related Servicer shall cause a flood insurance policy to be maintained with respect to such Non-Designated 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 a Mortgage related to a Non-Designated Mortgage Loan is secured by a unit in a condominium project, the related 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 requirements of the Servicer for mortgage loans that it services on its own account.

Each Servicer shall cause to be maintained on each Mortgaged Property related to a Non-Designated 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 Mortgage Guaranty Insurance Policy insurer, or as may be required to conform with Accepted Servicing Practices to the extent permitted by the Mortgage Note, the Mortgage or applicable law provided that the Servicer shall not be required to bear the cost of such insurance.

All policies required hereunder shall name the related 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.

Each Servicer shall not interfere with the Mortgagor’s freedom of choice at the origination of such Non-Designated Mortgage Loan in selecting either his insurance carrier or agent, provided, however, that such Servicer shall not accept any such insurance policies from insurance companies unless such companies are rated: B:III or better in Best’s or acceptable to FNMA or FHLMC and are licensed to do business in the jurisdiction in which the Mortgaged Property is located. The related 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 3.05, any amounts collected by a 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 Non-Designated Mortgage Loan, or to be released to the Mortgagor, in accordance with such Servicer’s normal servicing procedures) shall be deposited in the related Collection Account (subject to withdrawal pursuant to Section 3.08(a)).

Any cost incurred by a Servicer in maintaining any such insurance shall not, for the purpose of calculating monthly distributions to the Certificateholders or remittances to the Trust Administrator for their benefit, be added to the principal balance of the Non-Designated Mortgage Loan, notwithstanding that the terms of the Non-Designated Mortgage Loan so permit. Such costs shall constitute a Servicing Advance and will be reimbursable to the Servicer to the extent permitted by Section 3.08 hereof. It is understood and agreed that no earthquake or other additional insurance is to be required of any Mortgagor related to a Non-Designated Mortgage Loan or maintained on property acquired in respect of a Mortgage related to a Non-Designated 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 a Servicer shall obtain and maintain a blanket policy insuring against losses arising from fire and hazards covered under extended coverage on all of the related Non-Designated Mortgage Loans, then, to the extent such policy provides coverage in an amount equal to the amount required pursuant to Section 3.09(a) and otherwise complies with all other requirements of Section 3.09(a), it shall conclusively be deemed to have satisfied its obligations as set forth in Section 3.09(a). Any amounts collected by a Servicer under any such policy relating to a Non-Designated Mortgage Loan shall be deposited in the related Collection Account subject to withdrawal pursuant to Section 3.08(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 3.09(a), and there shall have been a loss which would have been covered by such policy, the related 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 such Servicer’s funds, without reimbursement therefor. Upon request of the Trust Administrator, a Servicer shall cause to be delivered to the Trust Administrator a certified true copy of such policy and a statement from the insurer thereunder that such policy shall in no event be terminated or materially modified without 30 days’ prior written notice to the Trust Administrator. In connection with its activities as Servicer of the related Non-Designated Mortgage Loans, such Servicer agrees to present, on behalf of itself, the Depositor, and the Trust Administrator for the benefit of the Certificateholders, claims under any such blanket policy.

(c)

With respect to each Non-Designated Mortgage Loan with a Loan-to-Value Ratio in excess of 80% which the related Seller represented to be covered by a Mortgage Guaranty Insurance Policy as of the Cut-off Date, the related Servicer shall, without any cost to the Depositor or Trust Administrator, maintain or cause the Mortgagor to maintain in full force and effect a Mortgage Guaranty Insurance Policy insuring that portion of the Non-Designated Mortgage Loan in excess of 75% of value, and shall pay or shall cause the Mortgagor to pay, the premium thereon on a timely basis, until the loan-to-value ratio of such Non-Designated 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 Non-Designated Mortgage Loan was originated. In the event that such Mortgage Guaranty Insurance Policy shall be terminated prior to the loan-to-value ratio of such Non-Designated Mortgage Loan being reduced to 80%, the related Servicer shall obtain from another Qualified Insurer a comparable replacement policy, with a total coverage equal to the remaining coverage of such terminated Mortgage Guaranty Insurance Policy. If the insurer shall cease to be a Qualified Insurer, the related Servicer shall determine whether recoveries under the Mortgage Guaranty Insurance Policy are jeopardized for reasons related to the financial condition of such insurer, it being understood that such Servicer shall in no event have any responsibility or liability for any failure to recover under the Mortgage Guaranty Insurance Policy for such reason. If the related Servicer determines that recoveries are so jeopardized, it shall notify the Mortgagor, if required, and obtain from another Qualified Insurer a replacement insurance policy. The related Servicer shall not take any action which would result in noncoverage under any applicable Mortgage Guaranty Insurance Policy of any loss which, but for the actions of such Servicer would have been covered thereunder. In connection with any assumption or substitution agreement entered into or to be entered into pursuant to Section 3.10, each Servicer shall promptly notify the insurer under the related Mortgage Guaranty Insurance Policy, if any, of such assumption or substitution of liability in accordance with the terms of such Mortgage Guaranty Insurance Policy and shall take all actions which may be required by such insurer as a condition to the continuation of coverage under such Mortgage Guaranty Insurance Policy provided that such required actions are in compliance with all applicable law. If such Mortgage Guaranty Insurance Policy is terminated as a result of such assumption or substitution of liability, the related Servicer shall obtain a replacement Mortgage Guaranty 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 Non-Designated Mortgage Loan covered by a Lender Paid Mortgage Guaranty Insurance Policy, the applicable Servicer shall effect timely payment of the premiums on such Mortgage Guaranty Insurance Policy from amounts on deposit in the Collection Account, or deducted by such Servicer prior to deposit into the applicable Collection Account pursuant to Section 3.05(c), with respect to such Non-Designated Mortgage Loan. If amounts on deposit in the Collection Account, or deducted by such Servicer prior to deposit into the applicable Collection Account pursuant to Section 3.05(c), with respect to such Non-Designated Mortgage Loan are not sufficient to pay the premiums on such Mortgage Guaranty Insurance Policy, the applicable Servicer shall effect timely payment of such premiums, and such costs shall be recoverable by such Servicer, as applicable, from the related Liquidation Proceeds or otherwise as a Servicing Advance pursuant to Section 3.08(a). With respect to each Non-Designated Mortgage Loan covered by a Mortgage Guaranty Insurance Policy that is not a Lender Paid Mortgage Guaranty Insurance Policy, the applicable Servicer shall effect timely payment of the premiums on such Mortgage Guaranty Insurance Policy, and such costs not otherwise recoverable from the Mortgagor shall be recoverable by such Servicer, as applicable, from the related Liquidation Proceeds or otherwise as a Servicing Advance pursuant to Section 3.08(a).

(d)

In connection with its activities as servicer, each Servicer shall prepare and present, on behalf of itself, the Depositor, the Trustee, the Trust Administrator and the Certificateholders, claims to the insurer under any Mortgage Guaranty Insurance Policy related to a Non-Designated Mortgage Loan in a timely fashion in accordance with the terms of such Mortgage Guaranty Insurance Policy and, in this regard, to take such reasonable action as shall be necessary to permit recovery under any Mortgage Guaranty Insurance Policy respecting defaulted Non-Designated Mortgage Loans. Pursuant to Section 3.05, any amounts collected by a Servicer under any Mortgage Guaranty Insurance Policy shall be deposited in the related Collection Account, subject to withdrawal pursuant to Section 3.08.

(e)

With respect to any Non-Designated Mortgage Loan, each Servicer need not obtain the approval of the Trustee or the Trust Administrator 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, each Servicer shall comply with the following conditions in connection with any such release of Insurance Proceeds:

(i)

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

(ii)

such 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, such Servicer shall place the Insurance Proceeds in the related Escrow Account.

(f)

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

SECTION 3.10

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

(a)

With respect to any Non-Designated Mortgage Loan, each 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 related Servicer shall, to the extent it has knowledge of such conveyance, exercise its rights to accelerate the maturity of such Non-Designated Mortgage Loan under the “due-on-sale” clause applicable thereto, provided, however, that such Servicer 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 Mortgage Guaranty Insurance Policy, if any.

(b)

With respect to any Non-Designated Mortgage Loan, if a Servicer reasonably believes it is unable under applicable law to enforce such “due-on-sale” clause, such 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 such 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, a Servicer shall not be deemed to be in default under this Section by reason of any transfer or assumption which such 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 Non-Designated Mortgage Loan or the outstanding principal amount of the Non-Designated Mortgage Loan shall be changed.

(c)

To the extent that any Non-Designated Mortgage Loan is assumable, the related 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 which are used by FNMA with respect to underwriting mortgage loans of the same type as the Non-Designated Mortgage Loans. If the credit of the proposed transferee does not meet such underwriting criteria, the related Servicer diligently shall, to the extent permitted by the Mortgage or the Mortgage Note and by applicable law, accelerate the maturity of the Non-Designated Mortgage Loan.

(d)

With respect to any Non-Designated Mortgage Loan, subject to each Servicer’s duty to enforce any due-on-sale clause to the extent set forth in this Section 3.10, in any case in which the related Mortgaged Property has been conveyed to a Person by the related 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 Non-Designated Mortgage Loan, such 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 related 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 related Servicer shall notify the Trustee and the Trust Administrator that any such substitution or assumption agreement has been completed by forwarding to the Trustee and the Trust Administrator a copy of such substitution or assumption agreement, and shall forward the original to the Custodian which 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 a Servicer for entering into an assumption or substitution of liability agreement will be retained by such Servicer as additional servicing compensation.

SECTION 3.11

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

(a)

Each Servicer shall use reasonable efforts to foreclose upon or otherwise comparably convert the ownership of properties securing such of the related Non-Designated 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, each Servicer shall take such action as (i) such 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) such Servicer shall determine consistently with Accepted Servicing Practices to be in the best interest of the Trust Fund and Certificateholders, and (iv) is consistent with the requirements of the insurer under any Required Insurance Policy; provided, however, that such 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 Non-Designated Mortgage Loan after reimbursement to itself of such expenses and (ii) that such expenses will be recoverable to it through Liquidation Proceeds. Any funds expended by any Servicer pursuant to this Section 3.11(a) shall be reimbursable in full pursuant to Section 3.08(a)(iii). The related 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 as a Servicing Advance in accordance with Section 3.08(a).

With respect to any Non-Designated 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 related Servicer has reasonable cause to believe that the related Mortgaged Property is contaminated by hazardous or toxic substances or wastes, or if the Trust Administrator otherwise requests, an environmental inspection or review of such Mortgaged Property conducted by a qualified inspector shall be arranged for by such Servicer. Upon completion of the inspection, the related Servicer shall promptly provide the Trust Administrator 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 related 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 and Advances made such 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, Advances and Servicing Advances are less than or equal to the estimated value of the Mortgaged Property, then the related 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 such 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 such Servicer, such Servicer shall be entitled to be reimbursed from amounts in the related Collection Account pursuant to Section 3.08(a) hereof. In the event the related Servicer does not proceed with foreclosure or acceptance of a deed in lieu of foreclosure pursuant to the first sentence of this paragraph, such Servicer shall be reimbursed for all Advances and Servicing Advances made with respect to the related Mortgaged Property from the related Collection Account pursuant to Section 3.08(a) hereof, and such Servicer shall have no further obligation to service such Non-Designated Mortgage Loan under the provisions of this Agreement.

(b)

With respect to any REO Property related to a Non-Designated Mortgage Loan, the deed or certificate of sale shall, subject to applicable laws, 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 related 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 related 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 related Servicer, either itself or through an agent selected by such 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. Upon request, the related Servicer shall furnish to the Trust Administrator 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 Servicer’s efforts in connection with the sale of such REO Property and any rental of such REO Property incidental to the sale thereof for the previous calendar month. That statement shall be accompanied by such other information as the Trust Administrator shall reasonably request and which is necessary to enable the Trust Administrator 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 related 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, in the form required, and delivering the same to the Trust Administrator for filing and, upon the request of the Trust Administrator, by delivering a copy of the same to the Trust Administrator.

To the extent consistent with Accepted Servicing Practices, the related Servicer shall also maintain on each REO Property related to a Non-Designated Mortgage Loan fire and hazard insurance with extended coverage in an amount which is equal to the outstanding principal balance of the related Non-Designated Mortgage Loan (as reduced by any amount applied as a reduction of principal at the time of acquisition of the REO Property), liability insurance 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 related 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 and the Trust Administrator 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 applicable Servicer shall have applied for, 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 related 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 obligors 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 related 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 a Servicer to foreclose on a defaulted Mortgage Loan shall be subject to a determination by such 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 such 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 Non-Designated 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 Non-Designated Mortgage Loan for such calendar month, such excess shall be considered to be a partial prepayment of principal of the related Mortgage Loan.

(e)

The proceeds from any liquidation of a Non-Designated Mortgage Loan, as well as any income from an REO Property, will be applied in the following order of priority: first, to reimburse the related Servicer for any related unreimbursed Servicing Advances and Servicing Fees; second, to reimburse such Servicer for any unreimbursed Advances; third, to reimburse the related Collection Account for any Nonrecoverable Advances (or portions thereof) that were previously withdrawn by such Servicer pursuant to Section 3.08(a)(iii) that related to such Non-Designated 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 Non-Designated Mortgage Loan or related REO Property, at the per annum rate equal to the related Mortgage Rate reduced by the related Servicing Fee Rate, and any primary mortgage guaranty insurance fee rate, if applicable, 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 Non-Designated Mortgage Loan. Excess proceeds, if any, from the liquidation of a Liquidated Mortgage Loan that is a Non-Designated Mortgage Loan (“Excess Proceeds”) will be retained by the related Servicer as additional servicing compensation pursuant to Section 3.14.

(f)

Each Servicer of the Non-Designated Mortgage Loans may (but is not obligated to) enter into a special servicing agreement with an unaffiliated holder of a 100% Percentage Interest of the most junior Class of Subordinate Certificates, subject to each Rating Agency’s acknowledgment that the Ratings of the Certificates in effect immediately prior to the entering into such agreement would not be qualified, downgraded or withdrawn and the Certificates would not be placed on credit review status (except for possible upgrading) as a result of such agreement. Any such agreement may contain provisions whereby such Holder may (i) instruct the related Servicer to commence or delay foreclosure proceedings with respect to delinquent Non-Designated Mortgage Loans and will contain provisions for the deposit of cash with such Servicer by the holder that would be available for distribution to Certificateholders if Liquidation Proceeds are less than they otherwise may have been had such Servicer acted in accordance with its normal procedures, (ii) purchase delinquent Non-Designated Mortgage Loans from the Trust Fund immediately prior to the commencement of foreclosure proceedings at a price equal to the Purchase Price, and/or (iii) assume all of the servicing rights and obligations with respect to delinquent Non-Designated Mortgage Loans so long as such Holder (A) meets the requirements for a Subservicer set forth in Section 3.02(a), (B) will service such Non-Designated Mortgage Loans in accordance with this Agreement and (C) the Servicer has the right to transfer such servicing rights without the payment of any compensation to a subservicer.

(g)

The Special Servicer, at its option, may (but is not obligated to) purchase from the Trust Fund, (a) any Mortgage Loan that is delinquent in payment 90 or more days or (b) any related Mortgage Loan with respect to which there has been initiated legal action or other proceedings for the foreclosure of the related Mortgaged Property either judicially or non-judicially, in each case, provided that the applicable servicer has the right to transfer the related servicing rights without the payment of any compensation to a subservicer. Any such purchase shall be made by the Special Servicer with its own funds at a price equal to the Purchase Price for such Mortgage Loan. The applicable Servicer shall be entitled to reimbursement from the Special Servicer for all expenses incurred by it in connection with the transfer of any Mortgage Loan to the Special Servicer pursuant to this Section 3.11(g). The Special Servicer shall notify the Master Servicer and each Servicer in writing of any purchase of Mortgage Loans pursuant to this Section 3.11(g).

SECTION 3.12

Trustee and Trust Administrator to Cooperate; Release of Mortgage Files.

Upon the payment in full of any Non-Designated Mortgage Loan, or the receipt by a Servicer of a notification that payment in full will be escrowed in a manner customary for such purposes, such Servicer or the Trust Administrator will immediately notify the Custodian, by delivering, or causing to be delivered a “Request for Release” substantially in the form of Exhibit J. Upon receipt of such request, the Custodian shall within three Business Days release the related Mortgage File to the related Servicer, and the Trustee shall within three Business Days of such Servicer’s direction execute and deliver to such 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 such Servicer, and the Custodian shall deliver the Mortgage Note with written evidence of cancellation thereon. Expenses incurred in connection with any instrument of satisfaction or deed of reconveyance shall be chargeable to the related Mortgagor. From time to time and as shall be appropriate for the servicing or foreclosure of any Non-Designated 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 Custodian within three Business Days of delivery to the Custodian of a Request for Release in the form of Exhibit J signed by a Servicing Officer, release the Mortgage File to the related Servicer. Subject to the further limitations set forth below, the related Servicer shall cause the Mortgage File or documents so released to be returned to the Custodian when the need therefor by such Servicer no longer exists, unless the Non-Designated Mortgage Loan is liquidated and the proceeds thereof are deposited in the related Collection Account, in which case such Servicer shall deliver to the Custodian a Request for Release in the form of Exhibit J, signed by a Servicing Officer. Each 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 a Servicer at any time seeks to initiate a foreclosure proceeding in respect of any Mortgaged Property related to a Non-Designated Mortgage Loan as authorized by this Agreement, such 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 3.13

Documents, Records and Funds in Possession a Servicer to be Held for the Trust.

Notwithstanding any other provisions of this Agreement, each Servicer shall transmit to the Custodian as required by this Agreement all documents and instruments in respect of a Non-Designated Mortgage Loan coming into the possession of the related Servicer from time to time required to be delivered to the Custodian pursuant to the terms hereof and shall account fully to the Trust Administrator for any funds received by such Servicer or which otherwise are collected by such Servicer as Liquidation Proceeds or Insurance Proceeds in respect of any Non-Designated Mortgage Loan. All Mortgage Files and funds collected or held by, or under the control of, a Servicer in respect of any Non-Designated 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 Collection Account, shall be held by the related Servicer for and on behalf of the Trust, the Trustee or the Trust Administrator and shall be and remain the sole and exclusive property of the Trust, subject to the applicable provisions of this Agreement. Each Servicer 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 Trust, the Trustee or the Trust Administrator 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 Non-Designated Mortgage Loan, except, however, that such Servicer shall be entitled to set off against and deduct from any such funds any amounts that are properly due and payable to such Servicer under this Agreement.

SECTION 3.14

Servicing Compensation and Master Servicing Compensation.

(a)

As compensation for its services hereunder, each Servicer shall be entitled to withdraw from the applicable Collection Account or to retain from interest payments on the related Mortgage Loans, the amount of its Servicing Fee for each Mortgage Loan serviced by it, less any amounts in respect of its Servicing Fee payable by such Servicer pursuant to Section 3.05(c)(vi). The Servicing Fee for each Servicer is limited to, and payable solely from, the interest portion of such Scheduled Payments collected by such Servicer or as otherwise provided in Section 3.08(a).

(b)

With respect to each Non-Designated Mortgage Loan, additional servicing compensation in the form of Ancillary Income, Payoff Interest (except, with respect to WMMSC, if such Payoff Interest is required for Compensating Interest Payments) and Excess Proceeds shall be retained by the related Servicer. Each 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 insurance required pursuant to Section 3.18) and shall not be entitled to reimbursement thereof except as specifically provided for in this Agreement.

(c)

The Master Servicer shall be compensated by the Trust Administrator as separately agreed. The Master Servicer and any director, officer, employee or agent of the Master Servicer shall be indemnified by DLJMC (or if DLJMC shall fail to do so, by the Trust) 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, (b) the Certificates or (c) the performance of any of the Master Servicer’s duties hereunder, other than any loss, liability or expense incurred by reason of willful misfeasance, bad faith or negligence in the performance of any of the Master Servicer’s duties hereunder or incurred by reason of any action of the Master Servicer taken at the direction of the Certificateholders; provided, however, that the sum of (x) such indemnity amounts payable by DLJMC or the Trust to the Master Servicer pursuant to this Section 3.14(c) and (y) the indemnity amounts payable by DLJMC or the Trust to the Trust Administrator pursuant to Section 10.05, shall not exceed $200,000 per year; provided, further, that any amounts not payable by DLJMC or the Trust to the Master Servicer due to the preceding proviso shall be payable by DLJMC (or if DLJMC fails to do so, by the Trust) in any succeeding year, subject to the aggregate $200,000 per annum limitation imposed by the preceding proviso. Such indemnity shall survive the termination of this Agreement or the resignation or removal of the Master Servicer hereunder.

SECTION 3.15

Access to Certain Documentation.

The Master Servicer and each 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 related Non-Designated Mortgage Loans required by applicable regulations of the OTS and the FDIC. Such access shall be afforded without charge, but only upon reasonable and prior written request and during normal business hours at the offices designated by the Master Servicer or such Servicer. Nothing in this Section shall limit the obligation of the Master Servicer or any Servicer to observe any applicable law prohibiting disclosure of information regarding the Mortgagors and the failure of the Master Servicer or such Servicer to provide access as provided in this Section as a result of such obligation shall not constitute a breach of this Section. Nothing in this Section 3.15 shall require the Master Servicer or any Servicer to collect, create, collate or otherwise generate any information that it does not generate in its usual course of business.

SECTION 3.16

Annual Statement as to Compliance.

SECTION 3.17

Annual Independent Public Accountants’ Servicing Statement; Financial Statements.

Not later than the earlier of (a) March 15 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 each 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), each Servicer (other than WMMSC) at its expense shall cause a nationally or regionally recognized firm of independent public accountants (who may also render other services to such Servicer, any Seller or any affiliate thereof) which is a member of the American Institute of Certified Public Accountants to furnish a statement to the Trust Administrator, to the effect that with respect to each Servicer other than WMMSC, such firm has examined certain documents and records relating to the servicing of mortgage loans which such Servicer is servicing which may include the related Mortgage Loans or similar mortgage loans, 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 each Servicer shall disclose to such firm all significant deficiencies relating to such Servicer’s compliance with the minimum servicing standards set forth in this Agreement. Upon the Trust Administrator’s receipt of such statement, the Trust Administrator shall send a copy of such statement to the Master Servicer and the Depositor. 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.

Not later than the earlier of (a) March 15 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 each 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), WMMSC, at its expense, shall furnish to the Trust Administrator a copy of a report delivered to WMMSC by a firm of independent public accountants (who may also render other services to WMMSC or any affiliate thereof) to the effect that, on the basis of an examination conducted by such firm in accordance with standards established by the American Institute of Certified Public Accountants, WMMSC has complied with certain minimum residential mortgage loan servicing standards in its role as master servicer with respect to the servicing of residential mortgage loans (including the WMMSC Serviced Mortgage Loans) during the most recently completed fiscal year. In rendering its report such firm may rely, (a) as to matters relating to the Certificates, upon a statistical sampling of series of mortgage-backed certificates which may include the Certificates and (b) as to matters relating to the direct servicing of residential mortgage loans by subservicers, upon comparable reports of firms of independent certified public accountants rendered on the basis of examinations conducted in accordance with the same standards (rendered within one year of such report) with respect to those subservicers. In addition, WMMSC shall disclose to such firm all significant deficiencies relating to WMMSC’s compliance with the minimum residential mortgage loan servicing standards referred to in the preceding sentence.

Copies of such statements shall be provided by the Trust Administrator to any Certificateholder upon request at the Master Servicer’s or the related Servicer’s expense, provided such statement is delivered by the Master Servicer or such Servicer to the Trust Administrator.

SECTION 3.18

Maintenance of Fidelity Bond and Errors and Omissions Insurance.

Each 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 Mortgage Banker’s Blanket Bond and shall protect and insure the related Servicer against losses, including forgery, theft, embezzlement, fraud, errors and omissions and negligent acts of such Servicer Employees. Such Fidelity Bond and Errors and Omissions Insurance Policy also shall protect and insure each 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 3.18 requiring such Fidelity Bond and Errors and Omissions Insurance Policy shall diminish or relieve a 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. Upon the request of the Trust Administrator, the related Servicer shall cause to be delivered to the Trust Administrator a certificate of insurance of the insurer and the surety including a statement from the surety and the insurer that such fidelity bond and insurance policy shall in no event be terminated or materially modified without 30 days’ prior written notice to the Trust Administrator.

The Master Servicer shall maintain insurance in such amounts generally acceptable for entities serving as master servicer.

SECTION 3.19

Special Serviced Mortgage Loans.

If directed by the Special Servicer and solely at the Special Servicer’s option, each Servicer, other than WMMSC (a “Transferring Servicer”), shall transfer the servicing of any Mortgage Loan (other than a WMMSC Serviced Mortgage Loan) 90 days or more delinquent to the Special Servicer. The Special Servicer shall thereupon assume all of the rights and obligations of the Transferring Servicer, as Servicer, hereunder arising thereafter and the Transferring Servicer shall have no further rights or obligations, as Servicer, hereunder with respect to such Mortgage Loan (except that the Special Servicer shall not be (i) liable for losses of the Transferring Servicer pursuant to Section 3.09 hereof or for any acts or omissions of the Transferring Servicer hereunder prior to the servicing transfer date, (ii) 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 (iii) deemed to have made any representations and warranties of the Transferring Servicer hereunder). Upon the transfer of the servicing of any such Mortgage Loan to the Special Servicer, the Special Servicer shall be entitled to the Servicing Fee and other compensation accruing after the servicing transfer date with respect to such Mortgage Loans pursuant to Section 3.14.

In connection with the transfer of the servicing of any Mortgage Loan to the Special Servicer, the Transferring Servicer, at the Special Servicer’s expense, shall deliver to the Special Servicer all documents and records relating to such Mortgage Loans 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 servicing to the Special Servicer. On the servicing transfer date, the Special Servicer shall reimburse the Transferring Servicer for all unreimbursed Advances, Servicing Advances and Servicing Fees relating to the Mortgage Loans for which the servicing is being transferred. The Special Servicer shall be entitled to be reimbursed pursuant to Section 3.08 or otherwise pursuant to this Agreement for all such Advances, Servicing Advances and Servicing Fees paid by the Transferring Servicer pursuant to this Section 3.19. In addition, the Special Servicer shall notify the Master Servicer of such transfer and the effective date of such transfer, and amend the Mortgage Loan Schedule to reflect that such Mortgage Loans are Special Serviced Mortgage Loans.

SECTION 3.20

Designated Mortgage Loans.

(a)

For and on behalf of the Certificateholders, the Master Servicer shall oversee and enforce the obligation of each Designated Servicer to service and administer the related Designated Mortgage Loans in accordance with the terms of the related Designated Servicing Agreement and shall have full power and authority to do any and all things which it may deem necessary or desirable in connection with such master servicing and administration. In performing its obligations hereunder, the Master Servicer shall act in a manner consistent with this Agreement and with customary and usual standards of practice of prudent mortgage loan master servicers. Furthermore, the Master Servicer shall oversee and consult with each Designated Servicer as necessary from time-to-time to carry out the Master Servicer’s obligations hereunder, and shall receive, review and evaluate all reports, information and other data provided to the Master Servicer by each Designated Servicer.

The Master Servicer shall terminate the rights and obligations of either Designated Servicer under the related Designated Servicing Agreement, upon the failure of such Designated Servicer to perform any of its obligations under such Designated Servicing Agreement, which failure results in an event of default as provided in the Section 8.01 of the EverBank Servicing Agreement, with respect to EverBank, or Section 14.01 of the HSBC Servicing Agreement, with respect to HSBC. In the event a Designated Servicer is terminated pursuant to the preceding sentence, the Master Servicer shall notify the Depositor and the Trust Administrator and shall either (a) select and engage a successor servicer of the related Mortgage Loans or (b) act as successor servicer of the related Mortgage Loans. In either case, the Designated Mortgage Loans related to such Designated Servicing Agreement shall be serviced by the successor to such Designated Servicer pursuant to the servicing provisions of this Agreement, and such Designated Mortgage Loans shall be deemed as “Non-Designated Mortgage Loans” under this Agreement; provided, however, it is understood and acknowledged by the parties hereto that there will be a period of transition (not to exceed 90 days) before the actual servicing functions can be fully transferred to such successor Designated Servicer. Such enforcement, including, without limitation, the legal prosecution of claims, termination of Designated Servicing Agreements and the pursuit of other appropriate remedies, shall be in such form and carried out to such an extent and at such time as the Master Servicer, in its good faith business judgment, would require were it the owner of the related Mortgage Loans. The Master Servicer shall pay the costs of such enforcement at its own expense, provided that the Master Servicer shall not be required to prosecute or defend any legal action except to the extent that the Master Servicer shall have received reasonable indemnity for its costs and expenses in pursuing such action.

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

(b)

Each month, if a Designated Servicer fails to make a required Advance by the date such Advance is required to be made under the related Designated Servicing Agreement, the Master Servicer shall on the Cash Remittance Date deposit in the amount of any required Advance in the Certificate Account.

(c)

Each month, the Master Servicer shall make Compensating Interest Payments with respect to the Designated Mortgage Loans to the extent provided in Section 3.03.

SECTION 3.21

Indemnification of Servicers and Master Servicer

Each Servicer, other than WMMSC, agrees to indemnify and hold the Master Servicer harmless from and against any and all losses, claims, expenses, costs, or liabilities (including attorneys fees and court costs) incurred by the Master Servicer as a result of or in connection with the failure by such Servicer to perform the obligations or responsibilities imposed upon or undertaken by such Servicer under this Agreement.

The Master Servicer agrees to indemnify and hold each Servicer, other than WMMSC, harmless from and against any and all losses, claims, expenses, costs, or liabilities (including attorneys fees and court costs) incurred by such Servicer as a result of or in connection with the failure by the Master Servicer to perform the obligations or responsibilities imposed upon or undertaken by the Master Servicer under this Agreement.

Such amount shall be paid to the Senior Certificates in such Group in the same priority as such Certificates would receive other distributions of principal pursuant to Section 4.01(I)(A); provided, however, that the Trust Administrator shall not make such distribution on such Distribution Date if (a) the Group C-B Percentage for such Distribution Date is greater than or equal to 200% of the Group C-B Percentage as of the Closing Date and (b) the average outstanding principal balance of each of the Group I and Group II Mortgage Loans delinquent 60 days or more (including all related REO Property and Mortgage Loans in foreclosure) over the last six months, as a percentage of the related Group C-B Component Balance, is less than 50%.

On each Distribution Date prior to the Credit Support Depletion Date for the Group III and Group IV Certificates, but after the date on which the aggregate Class Principal Balance of either the Group III or Group IV Certificates (other than the applicable Class P Certificates) has been reduced to zero, the Trust Administrator shall distribute the principal portion of Available Distribution Amount on the Mortgage Loans relating to such Certificates that will have been paid in full, to the holders of the Certificates of the other Certificate Group (other than any Class P Certificates). Such amount shall be paid to the Senior Certificates in such Group in the same priority as such Certificates would receive other distributions of principal pursuant to Section 4.01(I)(A); provided, however, that the Trust Administrator shall not make such distribution on such Distribution Date if (a) the Group D-B Percentage for such Distribution Date is greater than or equal to 200% of the Group D-B Percentage as of the Closing Date and (b) the average outstanding principal balance of each of the Group III and Group IV Mortgage Loans delinquent 60 days or more (including all related REO Property and Mortgage Loans in foreclosure) over the last six months, as a percentage of the related Group D-B Component Balance, is less than 50%.

(b)

If on any Distribution Date the Class Principal Balance of the Group I or Group II Certificates is greater than the aggregate Stated Principal Balance of the Mortgage Loans in the related Loan Group (net of the applicable Class P Fraction of each applicable Class P Mortgage Loan) (such Loan Group, an “Undercollateralized Group”), then the Trust Administrator shall reduce the Available Distribution Amount of the other Loan Group (such Loan Group, an “Overcollateralized Group”), as follows:

(1)

to add to the Available Distribution Amount of the Undercollateralized Group an amount equal to the lesser of (a) one month's interest on the Principal Transfer Amount of the Undercollateralized Group at the Required Coupon for such Loan Group and (b) the Available Distribution Amount of the Overcollateralized Group remaining after making distributions of interest to the Senior Certificates of the Overcollateralized Group on such Distribution Date pursuant to Section 4.01; and

(2)

to the Senior Certificates of the Undercollateralized Group (other than any Class P Certificates), to the extent of the principal portion of Available Distribution Amount of the Overcollateralized Group remaining after making distributions to the Senior Certificates of the Overcollateralized Group on such Distribution Date pursuant to Section 4.01, until the Class Principal Balance of the Senior Certificates (other than the Class P Certificates) of the Undercollateralized Group equals the aggregate Stated Principal Balance of the Mortgage Loans in the related Loan Group (less the applicable Class P Fraction of each Class P Mortgage Loan in such Loan Group). Payments shall be made to the Senior Certificates in the Undercollateralized Group in the same priority as such Certificates would receive other distributions of principal pursuant to Section 4.01(A).

(c)

If on any Distribution Date the Class Principal Balance of the Group III or Group IV Certificates is greater than the aggregate Stated Principal Balance of the Mortgage Loans in the related Loan Group (net of the applicable Class P Fraction of each applicable Class P Mortgage Loan) (such Loan Group, an “Undercollateralized Group”), then the Trust Administrator shall reduce the Available Distribution Amount of the other Loan Group (such Loan Group, an “Overcollateralized Group”), as follows:

ADVANCES BY THE MASTER SERVICER AND SERVICERS

SECTION 5.01

Advances by the Master Servicer and Servicers.

With respect to the Non-Designated Mortgage Loans, each Servicer shall deposit in the related Collection Account as Advances, an amount equal to all Scheduled Payments (with interest at the Mortgage Rate less the related Servicing Fee Rate) which were due on such Non-Designated Mortgage Loans serviced by it during the applicable Collection Period and which were delinquent at the close of business on the immediately preceding Determination Date. Each Servicer’s obligation to make such Advances as to any related Non-Designated Mortgage Loan will continue through the last Scheduled Payment due prior to the payment in full of such Non-Designated Mortgage Loan, or through the date that the related Mortgaged Property has, in the judgment of such Servicer, been completely liquidated. No Servicer shall be required to advance shortfalls of principal or interest resulting from the application of the Relief Act.

With respect to any Non-Designated Mortgage Loan, if the amount of Advances received from a Servicer, other than WMMSC, is less than the amount required to be advanced by such Servicer, the Master Servicer shall be obligated to remit to the Trust Administrator, for deposit by the Trust Administrator in the Certificate Account, a payment in an amount equal to such deficiency, subject to any determination by the Master Servicer that any portion of the amount required to be advanced is a Nonrecoverable Advance.

With respect to any Non-Designated Mortgage Loan, to the extent required by Accepted Servicing Practices, the Master Servicer and each Servicer shall be obligated to make Advances in accordance with the provisions of this Agreement; provided, however, that such obligation with respect to any related Non-Designated Mortgage Loan shall cease if the Master Servicer or a Servicer determines, in its reasonable opinion, that Advances with respect to such Non-Designated Mortgage Loan are Nonrecoverable Advances. In the event that the Master Servicer or such Servicer determines that any such advances are Nonrecoverable Advances, the Master Servicer or such Servicer shall provide the Trust Administrator with a certificate signed by a Servicing Officer evidencing such determination. Upon the Trust Administrator’s receipt of such certificate, the Trust Administrator shall send a copy of such certificate to the Trustee.

With respect to any of the Non-Designated Mortgage Loans, if an Advance is required to be made hereunder by a Servicer, such Servicer shall on the Cash Remittance Date either (i) deposit in the Collection Account from its own funds an amount equal to such Advance, (ii) cause to be made an appropriate entry in the records of the Collection Account that funds in such account being held for future distribution or withdrawal have been, as permitted by this Section 5.01, used by such 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 such Servicer from its own funds by deposit in such Collection Account on or before any future Distribution Date in which such funds would be due.

With respect to any Designated Mortgage Loan, the Master Servicer shall make Advances as required by Section 3.20(b) of this Agreement.

THE CERTIFICATES

SECTION 6.01

The Certificates.

The Certificates shall be in substantially the forms set forth in Exhibits A through F hereto, with such appropriate insertions, omissions, substitutions and other variations as are required or permitted by this Agreement or as may in the reasonable judgment of the Trust Administrator or the Depositor be necessary, appropriate or convenient to comply, or facilitate compliance, with applicable laws, and may have such letters, numbers or other marks of identification and such legends or endorsements placed thereon as may be required to comply with the rules of any securities exchange on which any of the Certificates may be listed, or as may, consistently herewith, be determined by the officers executing such Certificates, as evidenced by their execution thereof.

Subject to Section 10.02 respecting the final distribution on the Certificates, on each Distribution Date the Trust Administrator shall make distributions to each Certificateholder of record on the preceding Record Date either (x) by wire transfer in immediately available funds to the account of such holder at a bank or other entity having appropriate facilities therefor, if (i) such Holder has so notified the Trust Administrator 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 definitive Certificates shall be printed, typewritten, lithographed or engraved or produced by any combination of these methods or may be produced in any other manner permitted by the rules of any securities exchange on which any of the Certificates may be listed, all as determined by the officers executing such Certificates, as evidenced by their execution thereof.

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.

The Certificates shall be executed by manual or facsimile signature on behalf of the Trust Administrator by a Responsible Officer. Certificates bearing the manual or facsimile signatures of individuals who were, at the time when such signatures were affixed, authorized to sign on behalf of the Trust Administrator shall bind the Trust Administrator, notwithstanding that such individuals or any of them have ceased to be so authorized prior to the authentication and delivery of such Certificates or did not hold such offices at the date of such Certificate. No Certificate shall be entitled to any benefit under this Agreement, or be valid for any purpose, unless there appears on such Certificate a certificate of authentication executed by the Trust Administrator by manual signature, and such certificate of authentication upon any Certificate shall be conclusive evidence, and the only evidence, that such Certificate has been duly authenticated and delivered hereunder. All Certificates shall be dated the date of their authentication.

SECTION 6.02

Registration of Transfer and Exchange of Certificates.

(a)

The Trust Administrator shall maintain, or cause to be maintained, a Certificate Register in which, subject to such reasonable regulations as it may prescribe, the Trust Administrator shall provide for the registration of Certificates and of transfers and exchanges of Certificates as herein provided. Upon surrender for registration of transfer of any Certificate, the Trust Administrator shall execute, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates in like aggregate interest and of the same Class.

(b)

At the option of a Certificateholder, Certificates may be exchanged for other Certificates of authorized denominations and the same aggregate interest in the Trust Fund and of the same Class, upon surrender of the Certificates to be exchanged at the office or agency of the Trust Administrator set forth in Section 6.06. Whenever any Certificates are so surrendered for exchange, the Trust Administrator shall execute, authenticate and deliver the Certificates which the Certificateholder making the exchange is entitled to receive. Every Certificate presented or surrendered for registration of transfer or exchange shall be accompanied by a written instrument of transfer in form satisfactory to the Trust Administrator duly executed by the Holder thereof or his attorney duly authorized in writing.

(c)

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.

(d)

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

(e)

No transfer of any Private Certificate shall be made unless that transfer is made pursuant to an effective registration statement under the 1933 Act and effective registration or qualification under applicable state securities laws, or is made in a transaction which does not require such registration or qualification. 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 1933 Act and such laws, in order to assure compliance with the 1933 Act and such laws, the Certificateholder desiring to effect such transfer shall certify to the Trust Administrator in writing the facts surrounding the transfer in substantially the form set forth in Exhibit K (the “Transferor Certificate”) and such Certificateholder’s prospective transferee shall (i) deliver a letter in substantially the form of either (A) Exhibit L-1 (the “Investment Letter”), provided that all of the Private Certificates of a Class shall be transferred to one investor or the Depositor otherwise consents to such transfer, or (B) Exhibit L-2 (the “Rule 144A Letter”) or (ii) there shall be delivered to the Trust Administrator at the expense of the transferor an Opinion of Counsel that such transfer may be made pursuant to an exemption from the 1933 Act and the Depositor consents to such transfer. 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 1933 Act pursuant to the registration exemption provided by Rule 144A. The Trust Administrator 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 Trust Administrator, the Depositor, each Seller, the Master Servicer and each 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.

(f)

No transfer of an ERISA Restricted Certificate shall be made unless the Trust Administrator shall have received in accordance with Exhibit X-0, Xxxxxxx X-0 or Exhibit M, as applicable, either (i) a representation letter from the transferee of such Certificate, acceptable to and in form and substance satisfactory to the Trust Administrator, to the effect that such transferee is not an employee benefit plan or other retirement arrangement subject to Section 406 of ERISA or Section 4975 of the Code, or a person using the assets of any such plan or other retirement arrangement, which representation letter shall not be an expense of the Trust Administrator or the Trust Fund, (ii) 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 such Certificate presented for registration in the name of an employee benefit plan or other retirement arrangement subject to ERISA or Section 4975 of the Code (or comparable provisions of any subsequent enactments), or a person using such plan’s or arrangement’s assets, 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, the Trust Administrator, the Master Servicer, the Special Servicer, the Servicers or any other servicer to any obligation in addition to those undertaken in this Agreement, which Opinion of Counsel shall not be an expense of such parties or the Trust Fund. 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 Trust Administrator 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 plan or other retirement arrangement or person using a plan’s or arrangement’s assets is attempted without the delivery to the Trust Administrator of the Opinion of Counsel described above, the attempted transfer or acquisition of such Certificate shall be void and of no effect.

(g)

Additional restrictions on transfers of the Residual Certificates to Disqualified Organizations are set forth below:

(i)

Each Person who has or who acquires any ownership interest in a Residual Certificate shall be deemed by the acceptance or acquisition of such ownership interest to have agreed to be bound by the following provisions and to have irrevocably authorized the Trust Administrator or its designee under clause (iii)(A) below to deliver payments to a Person other than such Person and to negotiate the terms of any mandatory sale under clause (iii)(B) below and to execute all instruments of transfer and to do all other things necessary in connection with any such sale. The rights of each Person acquiring any ownership interest in a Residual Certificate are expressly subject to the following provisions:

(A)

Each Person holding or acquiring any ownership interest in a Residual Certificate shall be other than a Disqualified Organization and shall promptly notify the Trust Administrator of any change or impending change in its status as other than a Disqualified Organization.

(B)

In connection with any proposed transfer of any ownership interest in a Residual Certificate to a U.S. Person, the Trust Administrator shall require delivery to it, and shall not register the transfer of a Residual Certificate until its receipt of (1) an affidavit and agreement (a “Transferee Affidavit and Agreement” attached hereto as Exhibit M) from the proposed transferee, in form and substance satisfactory to the Trust Administrator, representing and warranting, among other things, that it is not a non-U.S. Person, that such transferee is other than a Disqualified Organization, that it is not acquiring its ownership interest in a Residual Certificate that is the subject of the proposed Transfer as a nominee, trustee or agent for any Person who is not other than a Disqualified Organization, that for so long as it retains its ownership interest in a Residual Certificate, it will endeavor to remain other than a Disqualified Organization, and that it has reviewed the provisions of this Section 6.02(g) and agrees to be bound by them, and (2) a certificate, attached hereto as Exhibit N, from the Holder wishing to transfer a Residual Certificate, in form and substance satisfactory to the Trust Administrator, representing and warranting, among other things, that no purpose of the proposed transfer is to allow such Holder to impede the assessment or collection of tax.

(C)

Notwithstanding the delivery of a Transferee Affidavit and Agreement by a proposed transferee under clause (B) above, if the Trust Administrator has actual knowledge that the proposed transferee is not other than a Disqualified Organization, no transfer of an ownership interest in a Residual Certificate to such proposed transferee shall be effected.

(D)

Each Person holding or acquiring any ownership interest in a Residual Certificate agrees, by holding or acquiring such ownership interest, to require a Transferee Affidavit and Agreement from the other Person to whom such Person attempts to transfer its ownership interest and to provide a certificate to the Trust Administrator in the form attached hereto as Exhibit N.

(ii)

The Trust Administrator shall register the transfer of any Residual Certificate only if it shall have received the Transferee Affidavit and Agreement, a certificate of the Holder requesting such transfer in the form attached hereto as Exhibit N and all of such other documents as shall have been reasonably required by the Trust Administrator as a condition to such registration.

(iii)

(A) If any Disqualified Organization shall become a Holder of a Residual Certificate, then the last preceding Holder that was other than a Disqualified Organization shall be restored, to the extent permitted by law, to all rights and obligations as Holder thereof retroactive to the date of registration of such transfer of such Residual Certificate. If any non-U.S. Person shall become a Holder of a Residual Certificate, then the last preceding Holder that is a U.S. Person shall be restored, to the extent permitted by law, to all rights and obligations as Holder thereof retroactive to the date of registration of the transfer to such non-U.S. Person of such Residual Certificate. If a transfer of a Residual Certificate is disregarded pursuant to the provisions of Treasury Regulations Section 1.860E-1 or Section 1.860G-3, then the last preceding Holder that was other than a Disqualified Organization shall be restored, to the extent permitted by law, to all rights and obligations as Holder thereof retroactive to the date of registration of such transfer of such Residual Certificate. The Trust Administrator shall be under no liability to any Person for any registration of transfer of a Residual Certificate that is in fact not permitted by this Section 6.02(g) or for making any payments due on such Certificate to the Holder thereof or for taking any other action with respect to such Holder under the provisions of this Agreement.

(B)

If any purported transferee of a Residual Certificate shall become a Holder of a Residual Certificate in violation of the restrictions in this Section 6.02(g) and to the extent that the retroactive restoration of the rights of the Holder of such Residual Certificate as described in clause (iii)(A) above shall be invalid, illegal or unenforceable, then the Depositor shall have the right, without notice to the Holder or any prior Holder of such Residual Certificate, to sell such Residual Certificate to a purchaser selected by the Depositor on such terms as the Depositor may choose. Such purported transferee shall promptly endorse and deliver a Residual Certificate in accordance with the instructions of the Depositor. Such purchaser may be the Depositor itself or any affiliate of the Depositor. The proceeds of such sale, net of the commissions (which may include commissions payable to the Depositor or its affiliates), expenses and taxes due, if any, shall be remitted by the Depositor to such purported transferee. The terms and conditions of any sale under this clause (iii)(B) shall be determined in the sole discretion of the Depositor, and the Depositor shall not be liable to any Person having an ownership interest or a purported ownership interest in a Residual Certificate as a result of its exercise of such discretion.

(iv)

The Master Servicer and each Servicer, on behalf of the Trust Administrator, shall make available, upon written request from the Trust Administrator, all information reasonably available to it that is necessary to compute any tax imposed (A) as a result of the transfer of an ownership interest in a Residual Certificate to any Person who is not other than a Disqualified Organization, including the information regarding “excess inclusions” of such Residual Certificate required to be provided to the Internal Revenue Service and certain Persons as described in Treasury Regulation Section 1.860D-1(b)(5), and (B) as a result of any regulated investment company, real estate investment trust, common trust fund, partnership, trust, estate or organizations described in Section 1381 of the Code having as among its record holders at any time any Person who is not other than a Disqualified Organization. Reasonable compensation for providing such information may be required by the Master Servicer, the Trust Administrator or the Servicer from such Person.

(v)

The provisions of this Section 6.02(g) set forth prior to this Section (v) may be modified, added to or eliminated by the Depositor, provided that there shall have been delivered to the Trust Administrator the following:

(A)

written notification from each Rating Agency to the effect that the modification, addition to or elimination of such provisions will not cause such Rating Agency to downgrade its then-current rating of the Certificates; and

(B)

a certificate of the Depositor stating that the Depositor has received an Opinion of Counsel, in form and substance satisfactory to the Depositor, to the effect that such modification, addition to or elimination of such provisions will not cause the Trust Fund to cease to qualify as a REMIC and will not create a risk that (i) the Trust Fund may be subject to an entity-level tax caused by the transfer of a Residual Certificate to a Person which is not other than a Disqualified Organization or (2) a Certificateholder or another Person will be subject to a REMIC-related tax caused by the transfer of applicable Residual Certificate to a Person which is not other than a Disqualified Organization.

(vi)

The following legend shall appear on each Residual Certificate:

ANY RESALE, TRANSFER OR OTHER DISPOSITION OF THIS CERTIFICATE MAY BE MADE ONLY IF THE PROPOSED TRANSFEREE PROVIDES A TRANSFER AFFIDAVIT TO THE SERVICER AND THE TRUST ADMINISTRATOR THAT (1) SUCH TRANSFEREE IS NOT (A) THE UNITED STATES, ANY STATE OR POLITICAL SUBDIVISION THEREOF, ANY FOREIGN GOVERNMENT, ANY INTERNATIONAL ORGANIZATION, OR ANY AGENCY OR INSTRUMENTALITY OF ANY OF THE FOREGOING, (B) ANY ORGANIZATION (OTHER THAN A COOPERATIVE DESCRIBED IN SECTION 521 OF THE CODE) WHICH IS EXEMPT FROM THE TAX IMPOSED BY CHAPTER 1 OF THE CODE UNLESS SUCH ORGANIZATION IS SUBJECT TO THE TAX IMPOSED BY SECTION 511 OF THE CODE, (C) ANY ORGANIZATION DESCRIBED IN SECTION 1381(a)(2)(C) OF THE CODE (ANY SUCH PERSON DESCRIBED IN THE FOREGOING CLAUSES (A), (B), OR (C) BEING HEREINAFTER REFERRED TO AS A “DISQUALIFIED ORGANIZATION”), OR (D) AN AGENT OF A DISQUALIFIED ORGANIZATION AND (2) NO PURPOSE OF SUCH TRANSFER IS TO ENABLE THE TRANSFEROR TO IMPEDE THE ASSESSMENT OR COLLECTION OF TAX. SUCH AFFIDAVIT SHALL INCLUDE CERTAIN REPRESENTATIONS AS TO THE FINANCIAL CONDITION OF THE PROPOSED TRANSFEREE. NOTWITHSTANDING THE REGISTRATION IN THE CERTIFICATE REGISTER OF ANY TRANSFER, SALE OR OTHER DISPOSITION OF THIS CERTIFICATE TO A DISQUALIFIED ORGANIZATION OR AN AGENT OF A DISQUALIFIED ORGANIZATION, SUCH REGISTRATION SHALL BE DEEMED TO BE OF NO LEGAL FORCE OR EFFECT WHATSOEVER AND SUCH PERSON SHALL NOT BE DEEMED TO BE A CERTIFICATEHOLDER FOR ANY PURPOSE HEREUNDER, INCLUDING, BUT NOT LIMITED TO, THE RECEIPT OF DISTRIBUTIONS ON THIS CERTIFICATE. EACH HOLDER OF THIS CERTIFICATE BY ACCEPTANCE OF THIS CERTIFICATE SHALL BE DEEMED TO HAVE CONSENTED TO THE PROVISIONS OF THIS PARAGRAPH.

(h)

The Trust Administrator shall have no liability to the Trust Fund arising from a transfer of any such Certificate in reliance upon a certification, ruling or Opinion of Counsel described in this Section 6.02; provided, however, that the Trust Administrator shall not register the transfer of any Residual Certificate if it has actual knowledge that the proposed transferee does not meet the qualifications of a permitted Holder of a Residual Certificate as set forth in this Section 6.02.

SECTION 6.03

Mutilated, Destroyed, Lost or Stolen Certificates.

If (a) any mutilated Certificate is surrendered to the Trust Administrator, or the Trust Administrator receives evidence to its satisfaction of the destruction, loss or theft of any Certificate and (b) there is delivered to each Servicer, the Trustee and the Trust Administrator such security or indemnity as may be required by them to save each of them harmless, then, in the absence of notice to the Trustee and the Trust Administrator that such Certificate has been acquired by a bona fide purchaser, the Trust Administrator shall execute, authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a new Certificate of like tenor and interest in the Trust Fund. In connection with the issuance of any new Certificate under this Section 6.03, the Trust Administrator may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trust Administrator) connected therewith. Any replacement Certificate issued pursuant to this Section 6.03 shall constitute complete and indefeasible evidence of ownership in the Trust Fund, as if originally issued, whether or not the lost, stolen or destroyed Certificate shall be found at any time.

SECTION 6.04

Persons Deemed Owners.

Prior to due presentation of a Certificate for registration of transfer, each Servicer, the Trust Administrator, and any agent of the Master Servicer or any Servicer, the Trust Administrator may treat the person in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions as provided in this Agreement and for all other purposes whatsoever, and none of the Master Servicer or the Servicers, the Trust Administrator, nor any agent of the Master Servicer or a Servicer or the Trust Administrator shall be affected by any notice to the contrary.

SECTION 6.05

Access to List of Certificateholders’ Names and Addresses.

(a)

If three or more Certificateholders (i) request in writing from the Trust Administrator a list of the names and addresses of Certificateholders, (ii) state that such Certificateholders desire to communicate with other Certificateholders with respect to their rights under this Agreement or under the Certificates and (iii) provide a copy of the communication which such Certificateholders propose to transmit, then the Trust Administrator shall, within ten Business Days after the receipt of such request, afford such Certificateholders access during normal business hours to a current list of the Certificateholders. The expense of providing any such information requested by a Certificateholder shall be borne by the Certificateholders requesting such information and shall not be borne by the Trust Administrator or the Trustee. Every Certificateholder, by receiving and holding a Certificate, agrees that the Trustee and the Trust Administrator shall not be held accountable by reason of the disclosure of any such information as to the list of the Certificateholders hereunder, regardless of the source from which such information was derived.

(b)

The Master Servicer and each Servicer, so long as it is a servicer hereunder, the Sellers and the Depositor shall have unlimited access to a list of the names and addresses of the Certificateholders which list shall be provided by the Trust Administrator promptly upon request.

SECTION 6.06

Maintenance of Office or Agency.

The Trust Administrator will maintain or cause to be maintained at its expense an office or offices or agency or agencies in Minneapolis, Minnesota where Certificates may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Trust Administrator in respect of the Certificates and this Agreement may be served. The Trust Administrator initially designates its Corporate Trust Office as its office for such purpose. The Trust Administrator will give prompt written notice to the Certificateholders of any change in the location of any such office or agency.

SECTION 6.07

Book-Entry Certificates.

Notwithstanding the foregoing, the Book-Entry Certificates, upon original issuance, shall be issued in the form of one or more typewritten Certificates representing the Book-Entry Certificates, to be delivered to DTC, the initial Clearing Agency, by, or on behalf of, the Depositor. The Book-Entry Certificates shall initially be registered on the Certificate Register in the name of Cede & Co., the nominee of DTC, as the initial Clearing Agency, and no Beneficial Holder will receive a definitive certificate representing such Beneficial Holder’s interest in the Certificates, except as provided in Section 6.09. Unless and until definitive, fully registered Certificates (“Definitive Certificates”) have been issued to the Beneficial Holders pursuant to Section 6.09:

(a)

the provisions of this Section 6.07 shall be in full force and effect with respect to the Book-Entry Certificates;

(b)

the Depositor and the Trust Administrator may deal with the Clearing Agency for all purposes with respect to the Book-Entry Certificates (including the making of distributions on such Certificates) as the sole Holder of such Certificates;

(c)

to the extent that the provisions of this Section 6.07 conflict with any other provisions of this Agreement, the provisions of this Section 6.07 shall control; and

(d)

the rights of the Beneficial Holders of the Book-Entry Certificates shall be exercised only through the Clearing Agency and the Participants and shall be limited to those established by law and agreements between such Beneficial Holders and the Clearing Agency and/or the Participants. Pursuant to the Depository Agreement, unless and until Definitive Certificates are issued pursuant to Section 6.09, the initial Clearing Agency will make book-entry transfers among the Participants and receive and transmit distributions of principal and interest on the related Book-Entry Certificates to such Participants.

For purposes of any provision of this Agreement requiring or permitting actions with the consent of, or at the direction of, Holders of the Book-Entry Certificates evidencing a specified percentage of the aggregate unpaid principal amount of such Certificates, such direction or consent may be given by the Clearing Agency at the direction of Beneficial Holders owning such Certificates evidencing the requisite percentage of principal amount of such Certificates. The Clearing Agency may take conflicting actions with respect to the Book-Entry Certificates to the extent that such actions are taken on behalf of the Beneficial Holders.

SECTION 6.08

Notices to Clearing Agency.

Whenever notice or other communication to the Holders of Book-Entry Certificates is required under this Agreement, unless and until Definitive Certificates shall have been issued to the related Certificateholders pursuant to Section 6.09, the Trust Administrator shall give all such notices and communications specified herein to be given to Holders of the Book-Entry Certificates to the Clearing Agency which shall give such notices and communications to the related Participants in accordance with its applicable rules, regulations and procedures.

SECTION 6.09

Definitive Certificates.

If (a) the Depositor advises the Trust Administrator in writing that the Clearing Agency is no longer willing or able to properly discharge its responsibilities under the Depository Agreement with respect to the Certificates and the Trust Administrator or the Depositor is unable to locate a qualified successor, (b) the Depositor, at its option, advises the Trust Administrator in writing that it elects to terminate the book-entry system with respect to the Book-Entry Certificates through the Clearing Agency or (c) after the occurrence of an Event of Default, Holders of Book-Entry Certificates evidencing not less than 66-2/3% of the aggregate Class Principal Balance of the Book-Entry Certificates advise the Trust Administrator in writing that the continuation of a book-entry system with respect to the such Certificates through the Clearing Agency is no longer in the best interests of the Holders of such Certificates with respect to the Book-Entry Certificates, the Trust Administrator shall notify all Holders of such Certificates of the occurrence of any such event and the availability of Definitive Certificates. Upon surrender to the Trust Administrator of the such Certificates by the Clearing Agency, accompanied by registration instructions from the Clearing Agency for registration, the Trust Administrator shall authenticate and deliver the Definitive Certificates. Neither the Depositor nor the Trust Administrator shall be liable for any delay in delivery of such instructions and may conclusively rely on, and shall be protected in relying on, such instructions. Upon the issuance of Definitive Certificates all references herein to obligations imposed upon or to be performed by the Clearing Agency shall be deemed to be imposed upon and performed by the Trust Administrator, to the extent applicable with respect to such Definitive Certificates, and the Trust Administrator shall recognize the Holders of Definitive Certificates as Certificateholders hereunder.
