Funds in the Certificate Account may (i) be held uninvested without liability for interest or compensation thereon or (ii) be invested at the direction of the Trust Administrator in Eligible Investments and reinvestment earnings thereon (net of investment losses) shall be paid to the Trust Administrator.

Certificate Balance:  With respect to any Certificate (other than a Notional Amount Certificate) at any date, the maximum dollar amount of principal to which the Holder thereof is then entitled hereunder, such amount being equal to the Denomination thereof (i) minus all distributions of principal and allocations of Realized Losses, including Applied Loss Amounts, as applicable, previously made or allocated with respect thereto pursuant to Section 4.02 and (ii) plus the amount of any increase to the Certificate Balance of such Certificate pursuant to Section 4.03.

If no such quotations can be obtained and no related Reference Bank Rate is available, the Certificate Index with respect to the LIBOR Certificates will be the Certificate Index applicable to such Certificates on the preceding Distribution Date.

In addition, in connection with the assignment of any MERS Mortgage Loan, the related Seller agrees that it shall cause, at the related Seller’s expense, the MERS® System to indicate that such Mortgage Loans have been assigned by the related Seller to the Trustee in accordance with this Agreement (and any Subsequent Transfer Agreement, if applicable) for the benefit of the Certificateholders by including (or deleting, in the case of Mortgage Loans which are repurchased or substituted in accordance with this Agreement) the information required by the MERS® System to (a) identify the Trustee and (b) identify the series of the Certificates issued in connection with such Mortgage Loans.  The Trustee shall confirm, or cause the related Custodian to confirm, on the Trust Receipt and Final Certification of the related Custodian whether or not such assignment has occurred.  The related Seller further agrees that it shall not, and shall not permit a Servicer to, and each related Servicer agrees that it shall not, alter the information referenced in this paragraph with respect to any Mortgage Loan during the term of this Agreement unless and until such Mortgage Loan is repurchased or substituted in accordance with the terms of this Agreement.  

Further, each Servicer is authorized and empowered by the Trustee, on behalf of the Certificateholders and the Trustee, in its own name or in the name of any Sub-Servicer, when a Servicer or any Sub-Servicer, as the case may be, believes it appropriate in its best judgment to register any Mortgage Loan on the MERS® System, or cause the removal from the registration of any Mortgage Loan on the MERS® System, to execute and deliver, on behalf of the Trustee and the Certificateholders or any of them, any and all instruments of assignment and other comparable instruments with respect to such assignment or re-recording of a Mortgage in the name of MERS, solely as nominee for the Trustee and its successors and assigns.  Any costs incurred by a Servicer pursuant to this paragraph shall be considered a Servicing Advance and shall be reimburseable to such Servicer.

In the event the Depositor delivers to a Custodian certified copies of any document or instrument set forth in 2.01(b) because of a delay caused by the public recording office in returning any recorded document, the Depositor shall deliver or cause to be delivered to such Custodian, within 60 days of the Closing Date or the related Subsequent Transfer Date, as applicable, an Officer’s Certificate which shall (i) identify the recorded document, (ii) state that the recorded document has not been delivered to such Custodian due solely to a delay caused by the public recording office, and (iii) state the amount of time generally required by the applicable recording office to record and return a document submitted for recordation.

In the event that in connection with any Mortgage Loan the Depositor cannot deliver (a) for a Mortgage Loan that is not a MERS Mortgage Loan, the original recorded Mortgage, (b) all interim recorded assignments or (c) the lender’s title policy (together with all riders thereto) satisfying the requirements set forth above, concurrently with the execution and delivery hereof because such document or documents have not been returned from the applicable public recording office in the case of clause (a) or (b) above, or because the title policy has not been delivered to the related Seller or the Depositor by the applicable title insurer in the case of clause (c) above, the Depositor shall promptly deliver to the related Custodian, in the case of clause (a) or (b) above, such original Mortgage or such interim assignment, as the case may be, with evidence of recording indicated thereon upon receipt thereof from the public recording office, or a copy thereof, certified, if appropriate, by the relevant recording office and, in the case of clause (c) above, any title policy upon receipt from the applicable title insurer.

As promptly as practicable subsequent to such transfer and assignment, and in any event, within thirty (30) days thereafter, DLJMC shall, at its expense, (i) affix or cause to be affixed the Trustee’s name to each Assignment of Mortgage, as the assignee thereof, (ii) cause such assignment to be in proper form for recording in the appropriate public office for real property records within thirty (30) days after receipt thereof and (iii) cause to be delivered for recording in the appropriate public office for real property records the assignments of the Mortgages to the Trustee, except that, with respect to any assignment of a Mortgage as to which DLJMC has not received the information required to prepare such assignment in recordable form, DLJMC’s obligation to do so and to deliver the same for such recording shall be as soon as practicable after receipt of such information and in any event within thirty (30) days after the receipt thereof, and DLJMC need not cause to be recorded any assignment which relates to a Mortgage Loan in any jurisdiction under the laws of which, as evidenced by an Opinion of Counsel delivered by the Depositor (at the Depositor’s expense) to the Trustee, the Trust Administrator and DLJMC, acceptable to the Rating Agencies, the recordation of such assignment is not necessary to protect the Trustee’s and the Certificateholders’ interest in the related Mortgage Loan.

If any original Mortgage Note referred to in Section 2.01(b)(i) above cannot be located, the obligations of the Depositor to deliver such documents shall be deemed to be satisfied upon delivery to the related Custodian of a photocopy of such Mortgage Note, if available, with a lost note affidavit and indemnity.  If any of the original Mortgage Notes for which a lost note affidavit and indemnity was delivered to the Custodian is subsequently located, such original Mortgage Note shall be delivered to such Custodian within three (3) Business Days.

(c)

The Trustee and the Trust Administrator are authorized to enter into one or more Custodial Agreements, at the direction of the Depositor, for the purpose of having a Custodian maintain custody of the documents and instruments referred to in this Section 2.01, and any documents delivered thereunder shall be delivered to such Custodian and any Officer’s Certificates delivered with respect thereto shall be delivered to the Trustee, the Trust Administrator and such Custodian.

(d)

It is the express intent of the parties to this Agreement that the conveyance of the Mortgage Loans by the Depositor to the Trustee as provided in this Section 2.01 be, and be construed as, a sale of the Mortgage Loans by the Depositor to the Trustee.  It is, further, not the intention of the parties to this Agreement that such conveyance be deemed a pledge of the Mortgage Loans by the Depositor to the Trustee to secure a debt or other obligation of the Depositor.  However, in the event that, notwithstanding the intent of the parties to this Agreement, the Mortgage Loans are held to be the property of the Depositor, or if any for any other reason this Agreement is held or deemed to create a security interest in the Mortgage Loans then (a) this Agreement shall also be deemed to be a security agreement within the meaning of Articles 8 and 9 of the New York Uniform Commercial Code; (b) the conveyance provided for in this Section 2.01 shall be deemed to be a grant by the Depositor to the Trustee for the benefit of the Certificateholders of a security interest in all of the Depositor’s right, title and interest in and to the Trust Fund and all proceeds of the conversion, voluntary or involuntary, of any portion of the Trust Fund into cash or other liquid property; (c) the possession by the Trustee or any Custodian of such items of property and such other items of property as constitute instruments, money, negotiable documents or chattel paper shall be deemed to be “in possession by the secured party” for purposes of perfecting the security interest pursuant to Section 9-313 of the New York Uniform Commercial Code; and (d) notifications to persons holding such property, and acknowledgments, receipts or confirmations from persons holding such property, shall be deemed notifications to, or acknowledgments, receipts or confirmations from, financial intermediaries, bailees or agents (as applicable) of the Trustee for the benefit of the Certificateholders for the purpose of perfecting such security interest under applicable law (except that nothing in this clause (d) shall cause any person to be deemed to be an agent of the Trustee for any purpose other than for perfection of such security interests unless, and then only to the extent, expressly appointed and authorized by the Trustee in writing).  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.

(e)

The Depositor hereby authorizes and directs the Trust Administrator to (i) execute the Interest Rate Cap Agreements and Swap Agreements, and (ii) to ratify, on behalf of the Trust, the terms agreed to by the Depositor with respect to the Interest Rate Cap Agreements and Swap Agreements.  The Depositor shall pay or cause to be paid on behalf of the Trust the payments owed to the Counterparties as of the Closing Date pursuant to the terms of the Interest Rate Cap Agreements and Swap Agreements.  

(f)

Upon one Business Day’s prior written notice to the Trustee, the Trust Administrator and the Rating Agencies, on any Business Day designated by the Depositor during a Prefunding Period, the Depositor, the Seller and the Trustee shall complete, execute and deliver a Subsequent Transfer Agreement.

The transfer of Subsequent Mortgage Loans and the other property and rights relating to them on a Subsequent Transfer Date is subject to the satisfaction of the conditions set forth in Section 2.01(f) of the Series Supplement and each of the following conditions:

(i)   each Subsequent Mortgage Loan conveyed on such Subsequent Transfer Date satisfies the representations and warranties applicable to it under this Agreement as of the applicable Subsequent Transfer Date; provided, however, that with respect to a breach of a representation and warranty with respect to a Subsequent Mortgage Loan, the obligation under Section 2.03 of this Agreement of the Seller to cure, repurchase or replace such Subsequent Mortgage Loan shall constitute the sole remedy against the Seller respecting such breach available to Certificateholders, the Depositor or the Trustee;

(ii)   the Rating Agencies shall have been provided with an Opinion of Counsel or Opinions of Counsel (dated as of the Closing Date), at the expense of the Depositor, with respect to the characterization of the transfer of the Subsequent Mortgage Loans conveyed on such Subsequent Transfer Date as a sale;

(iii) the execution and delivery of such Subsequent Transfer Agreement or conveyance of the related Subsequent Mortgage Loans does not result in a reduction or withdrawal of any ratings assigned to the Certificates on the Closing Date by the Rating Agencies;

(iv)   no Subsequent Mortgage Loan conveyed on such Subsequent Transfer Date was 30 or more days contractually Delinquent as of such Subsequent Transfer Date;

(v)   the remaining term to stated maturity of such Subsequent Mortgage Loan will not exceed 30 years;

(vi)   the Depositor shall have deposited in the Collection Account all principal and interest collected with respect to the related Subsequent Mortgage Loans on or after the related Subsequent Cut-off Date;

(xii)   such Subsequent Mortgage Loan will be otherwise acceptable to the Rating Agencies; and

(xiii)   no Subsequent Mortgage Loan will be subject to the Homeownership and Equity Protection Act of 1994 or any comparable state or local law.

(g)

Upon (1) delivery to the Trustee and the Trust Administrator by the Depositor of a revised Mortgage Loan Schedule reflecting the Subsequent Mortgage Loans conveyed on such Subsequent Transfer Date and (2) delivery to the Trustee and the Trust Administrator by the Depositor of an Officer’s Certificate confirming the satisfaction of each of the conditions precedent set forth in Section 2.01(f), the Trust Administrator shall remit to the Depositor the Aggregate Subsequent Transfer Amount related to the Subsequent Mortgage Loans transferred by the Depositor on such Subsequent Transfer Date from funds in the related Prefunding Account.

The Trustee and the Trust Administrator shall not be required to investigate or otherwise verify compliance with the conditions set forth in the preceding paragraph, except for its own receipt of documents specified above, and shall be entitled to rely on the required Officer’s Certificate.

(h)

Except as specifically set forth in this Agreement or by separate written agreement among the related parties hereto, the Depositor, the Seller(s), each Servicer and the Master Servicer agree that the provisions of this Agreement shall supersede any provisions in any existing mortgage loan purchase agreement or servicing agreement with respect to the Mortgage Loans for which the Depositor, the Seller(s), a Servicer or the Master Servicer may be a party.

(i)

The Trustee and the Trust Administrator are each hereby directed, on or prior to the Closing Date, not in their individual capacities but solely on behalf of the Trust, to execute and deliver each of the Designated Servicing Agreements in the forms presented to them by the Depositor, for the benefit of the Holders of the Certificates.  Neither the Trust Administrator nor the Trustee shall be personally liable for the payment of any indebtedness or expenses of the Trust or be liable for the breach or failure of any obligation, representation, warranty or covenant made or undertaken by the Trust Administrator or Trustee, as applicable, on behalf of the Trust under the Designated Servicing Agreements or any other related documents, as to all of which recourse shall be had solely to the assets of the Trust in accordance with the terms of this Agreement.  Every provision of this Agreement relating to the conduct or affecting the liability of or affording protection to the Trust Administrator or the Trustee, as applicable, shall apply to the Trust Administrator’s and the Trustee’s execution of each Designated Servicing Agreement and the performance of any obligations thereunder.

SECTION 2.02.

Acceptance by the Trustee.

(a)

The Trustee shall, or pursuant to the related Custodial Agreement the Trustee shall require each Custodian to, execute and deliver on the Closing Date to the Depositor, the Trustee and the Trust Administrator a Trust Receipt and Initial Certification with respect to the Mortgage Loans in the form annexed hereto as Exhibit I-1 (or in the related form annexed to the applicable Custodial Agreement).  Such Trust Receipt and Initial Certification shall require the related Custodian, based on its review and examination, and only as to the documents identified in such Trust Receipt and Initial Certification, to acknowledge that such documents appear regular on their face and relate to such Mortgage Loan.  The Custodians shall not be required 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.

The Trustee shall, or pursuant to the related Custodial Agreement the Trustee shall require each Custodian to, not later than 90 days after the Closing Date, deliver to the Depositor, the Trustee and the Trust Administrator a Trust Receipt and Final Certification with respect to the Mortgage Loans, in the form annexed hereto as Exhibit J (or in the form annexed to the applicable Custodial Agreement), with any applicable exceptions noted thereon.

Based solely upon the Trust Receipt and Initial Certification received from the Custodians, and subject to the provisions of Section 2.01 and any exceptions noted on an 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 shall hold such documents and the other documents delivered to it constituting the Mortgage File, and that it holds or shall 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, a Custodian finds any document constituting a part of a Mortgage File which does not meet the requirements of Section 2.01, such Custodian shall list such as an exception in the Trust Receipt and Final Certification pursuant to the related Custodial Agreement.  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 and such defect materially and adversely affects the interests of Certificateholders in the related Mortgage Loan, 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 that 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 or title insurer, as applicable; provided, however, that the related Seller shall have no liability for recording any Assignment of Mortgage in favor of the Trustee or for the Custodian’s failure to perform its obligation to record such Assignment of Mortgage if such recordation is required hereunder or under the terms of the related Custodial Agreement; and provided, further, that no related Seller shall be obligated to repurchase, substitute or cure any Mortgage Loan solely as a result of a Custodian’s failure to perform its obligation to record such Assignment of Mortgage if such recordation is required under the terms of the related Custodial Agreement.  The Trust Administrator shall deliver or direct the related Custodian to deliver to each Rating Agency written notice within 270 days from the Closing Date indicating each Mortgage Loan (i) for which a mortgage or assignment of mortgage required to be recorded hereunder has not been returned by the appropriate recording office or (ii) 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 related Custodian.  Any such substitution pursuant to clauses (a) or (b) above shall not be effected prior to the delivery to the Trustee and the Trust Administrator of (1) the Opinion of Counsel required by Section 2.05, if any, and (2) a Request for Release substantially in the form of Exhibit K.  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 remitted by the related Seller to the related Servicer for deposit in the related Collection Account on or prior to the Business Day immediately preceding such Distribution Date in the month following the month during which the related Seller became obligated hereunder to repurchase or replace such Mortgage Loan.  Upon receipt of such remittance, the related Servicer shall deliver a Request for Release with respect thereto substantially in the form of Exhibit K to the related Custodian, with copies to the Trustee and the Trust Administrator, and upon receipt of such Request for Release, the related Custodian shall release the related Mortgage File held for the benefit of the Certificateholders 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 transfer title from the Trustee to the related Seller.

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.

(b)

The related Custodian shall execute and deliver prior to 10:00 a.m. (New York City time) on each Subsequent Transfer Date to the Depositor, the Trust Administrator and each Servicer, a Trust Receipt and Subsequent Certification in the form annexed hereto as Exhibit I-2.  Based on its review and examination, and only as to the documents identified in such Trust Receipt and Subsequent Certification, the Custodian shall acknowledge that such documents appear regular on their face and relate to such Subsequent Mortgage Loan.  None of the Trustee, the Trust Administrator or the related 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 each Prefunding Period, the related Custodian shall deliver to the Depositor, the Trust Administrator, the Seller and each Servicer a Trust Receipt and Final Certification with respect to the related Subsequent Mortgage Loans in the form annexed hereto as Exhibit J with any applicable exceptions noted thereon.

If, in the course of such review of the Mortgage Files relating to the Subsequent Mortgage Loans, the related Custodian finds any document constituting a part of a Mortgage File which does not meet the requirements of Section 2.01, such Custodian shall list such as an exception in the Trust Receipt and Final Certification; provided, however, that such 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 cure any such defect or repurchase or substitute for any such Mortgage Loan in accordance with Section 2.02(a).

(c)

It is understood and agreed that the obligation of the related 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 the related Seller.

(d)

With respect to any Mortgage Loan that is delinquent (under the “MBA” method), in default or default is reasonably forseeable and for which the related Seller reasonably believes breaches a representation, warranty or covenant under the mortgage loan purchase agreement pursuant to which the related Seller purchased from the originator or prior holder of such Mortgage Loan, the related Seller shall have the right to (i) repurchase such Mortgage Loan from the Trust at any time in order to facilitate its rights against such originator or prior holder of such Mortgage Loan at a price equal to the Purchase Price or (ii) substitute in its place a Qualified Substitute Mortgage Loan in the manner and subject to the conditions relating to substitutions set forth in Section 2.03; provided, however, that any such substitution pursuant to clause (ii) 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, if any, and any such substitution pursuant to clause (ii) above shall not be effected prior to the additional delivery from the related Servicer to the Trustee, the Trust Administrator and the related Custodian of a Request for Release substantially in the form of Exhibit K relating to the Deleted Mortgage Loan and the Mortgage File for any such Qualified Substitute Mortgage Loan; provided, further, that in no event shall such repurchases or substitutions take place with respect to Mortgage Loans constituting more than 5% of the aggregate Cut-off Date Principal Balance of the Mortgage Loans plus amounts on deposit in the Prefunding Account(s), if any, as of the Closing Date.  

In the event that the related Seller exercises its option to repurchase a Mortgage pursuant to the preceding paragraph, the Purchase Price for any such Mortgage Loan shall be remitted by the related Seller to the related Servicer for deposit in the related Collection Account.  Upon receipt of such remittance, the related Servicer shall deliver a Request for Release with respect thereto substantially in the form of Exhibit K to the related Custodian, with copies to the Trustee and the Trust Administrator, and upon receipt of such Request for Release, the related Custodian shall release the related Mortgage File held for the benefit of the Certificateholders 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 transfer title from the Trustee to the related Seller.  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.  For the avoidance of doubt, any such repurchase by the Seller pursuant to this provision shall be subject to the limitations of Section 2.03(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.  The Seller hereby covenants that within 90 days of the earlier of its discovery or its receipt of written notice from any party of a breach of any representation or warranty made by it pursuant to Section 2.03(b) which materially and adversely affects the interests of the Certificateholders in any Mortgage Loan sold by the 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 2.03; 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, if any, and any such substitution pursuant to (i) above shall not be effected prior to the additional delivery from the related Servicer to the Trustee, the Trust Administrator and the related Custodian of a Request for Release substantially in the form of Exhibit K relating to the Deleted Mortgage Loan and the Mortgage File for any such Qualified Substitute Mortgage Loan. The Seller shall promptly reimburse the Trustee, the Trust Administrator, the Special Servicer and the related Servicer (if such Servicer is not the Seller of such Mortgage Loan) for any actual out of pocket expenses reasonably incurred by the Trustee, the Trust Administrator, the Special Servicer and the related Servicer (if such Servicer is not the Seller of such Mortgage Loan) in respect of enforcing the remedies for such breach.  With respect to any representation and warranties described in this Section 2.03 which are made to the best of the Seller’s knowledge if it is discovered by any of the Depositor, the Master Servicer, the Seller, any Servicer, the Special Servicer, the Modification Oversight Agent, the Trustee or the Trust Administrator that the substance of such representation and warranty is inaccurate and such inaccuracy materially and adversely affects the value of the related Mortgage Loan or the interests of the Certificateholders therein, notwithstanding the Seller’s lack of knowledge with respect to the substance of such representation or warranty, such inaccuracy shall be deemed a breach of the applicable representation or warranty.

With respect to any Qualified Substitute Mortgage Loan or Loans, the Seller shall deliver to the related 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 shall be retained by the 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 Seller shall be entitled to retain all amounts received in respect of such Deleted Mortgage Loan.  The 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 Seller shall deliver the amended Mortgage Loan Schedule to the Trustee, the Servicers 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 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 related Custodian to release the Mortgage File held for the benefit of the Certificateholders relating to such Deleted Mortgage Loan to the Seller and the Trustee shall execute and deliver at the Seller’s direction such instruments of transfer or assignment prepared by the Seller, in each case without recourse, as shall be necessary to vest title in the Seller, or its designee, the Trustee’s interest in any Deleted Mortgage Loan substituted for pursuant to this Section 2.03.

For any month in which the Seller substitutes one or more Qualified Substitute Mortgage Loans for one or more Deleted Mortgage Loans, the Master 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 (i) an amount equal to the aggregate of any unreimbursed Advances, Servicing Advances and unpaid Servicing Fees with respect to such Deleted Mortgage Loans and (ii) any costs and damages actually incurred and paid by or on behalf of the Trust in connection with any breach of the representation and warranty set forth in Schedule III(vii) as a result of a violation of a predatory or abusive lending law applicable to such Mortgage Loan, shall be remitted to the related Servicer for deposit in the related Collection Account by the 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.  Upon receipt of such remittance, the related Servicer shall deliver a Request for Release with respect thereto substantially in the form of Exhibit K to the related Custodian, with copies to the Trustee and the Trust Administrator.  

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

In the event that the Seller shall be required to repurchase a Mortgage Loan pursuant to this Agreement, the Purchase Price therefor shall be remitted to the related Servicer for deposit in the related Collection Account on or before the Business Day immediately preceding the Distribution Date in the month following the month during which the Seller became obligated hereunder to repurchase or replace such Mortgage Loan.  Upon receipt of such remittance of the Purchase Price, the related Servicer shall deliver a Request for Release with respect thereto substantially in the form of Exhibit K to the related Custodian, with copies to the Trustee and the Trust Administrator, and upon receipt of such Request for Release, the related 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 Custodians for the benefit of the Certificateholders.

Notwithstanding the foregoing, the substitution of a Deleted Mortgage Loan or the repurchase of a Mortgage Loan by the Seller shall be subject to, and shall in no way adversely affect, the rights of the owner of the servicing rights related to 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 related 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 or Section 2.03 shall be made more than ninety (90) days after the Closing Date unless the 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 created hereunder to fail to qualify as a REMIC at any time that any Certificates are outstanding; provided, however, that no Opinion of Counsel shall be required if (A) the substitution occurs within two years of the Closing Date and (B) the substitution occurs with respect to Mortgage Loans that are “defective” under the Code and the Seller delivers to the Trustee and the Trust Administrator an Officer’s Certificate substantially in the form of Exhibit Z.

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, 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.

As set forth in Section 2.07 of the Series Supplement.

SECTION 2.08.

Covenants of the Master Servicer and each Servicer.

(a)

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

(i)

Such Servicer or the Master Servicer (to the extent it is a successor servicer) shall comply in the performance of its obligations under this Agreement in all material respects with all reasonable rules and requirements of the insurer under each Mortgage Guaranty Insurance Policy; and

(ii)

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

The Master Servicer and each Servicer hereby agrees to indemnify the Trust Fund, the Depositor, the Master Servicer, the Trust Administrator and the Trustee for losses, damages, penalties, fines, forfeitures, reasonable and necessary legal fees and related costs, judgments and other costs and expenses imposed on or incurred by the Trust Fund, the Depositor, the Master Servicer, the Trust Administrator or the Trustee, as a result of a breach of the Master Servicer’s or such Servicer’s, as applicable, covenants set forth above in Section 2.08(a); provided, that the Master Servicer shall not provide indemnification for any damages caused by information provided to the Master Servicer by any other party to this Agreement, any Designated Servicer, any Interest Rate Cap Counterparty, any Swap Counterparty, any Custodian, any Subcontractor or any Sub-Servicer.

ARTICLE III

ADMINISTRATION AND SERVICING

OF MORTGAGE LOANS

SECTION 3.01.

Servicers to Service Mortgage Loans.

For and on behalf of the Certificateholders, as independent contractors of the Trust, (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 and with all applicable requirements of the Servicing Criteria, (ii) the Master Servicer shall, in accordance with Section 3.03 of this Agreement, master service and administer the Non-Designated Mortgage Loans (other than the WMMSC Serviced Mortgage Loans) by overseeing and enforcing the servicing of the Non-Designated Mortgage Loans (other than the WMMSC Serviced 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 GreenPoint, SPS, Wells Fargo, WMMSC, Bank of America and UMS hereunder to service and administer the Mortgage Loans shall be limited to the GreenPoint Serviced Mortgage Loans, the SPS Serviced Mortgage Loans, the Wells Fargo Serviced Mortgage Loans, the WMMSC Serviced Mortgage Loans, the Bank of America Serviced Mortgage Loans, and the UMS 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 GreenPoint Serviced Mortgage Loans (and the related proceeds thereof and related REO Properties) in the case of GreenPoint, the SPS Serviced Mortgage Loans (and the related proceeds thereof and related REO Properties) in the case of SPS, the Wells Fargo Serviced Mortgage Loans (and the related proceeds thereof and related REO Properties) in the case of Wells Fargo, the WMMSC Serviced Mortgage Loans (and the related proceeds thereof and related REO Properties) in the case of WMMSC, the Bank of America Serviced Mortgage Loans (and the related proceeds thereof and related REO Properties) in the case of Bank of America, and the UMS Serviced Mortgage Loans (and the related proceeds thereof and related REO Properties) in the case of UMS; 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 GreenPoint Serviced Mortgage Loans, the SPS Serviced Mortgage Loans, the Wells Fargo Serviced Mortgage Loans, the Bank of America Serviced Mortgage Loans, the UMS Serviced Mortgage Loans, the Special 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 through Sub-Servicers as provided in Section 3.02, 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 Trust, 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 a 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 that 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 Trust, is hereby authorized and empowered by the Depositor, the Trust 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 Trust, 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 service 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.

In accordance with the standards of the first paragraph of this Section 3.01 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 the 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 shall any Servicer be required to make any Servicing Advance which 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 the 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; provided, however, that the limitations contained in this sentence shall not apply to modifications made pursuant to Section 3.05(a).  The parties to this Agreement acknowledge that Servicing Advances shall be reimbursable pursuant to the terms of this Agreement and agree that no Servicing Advance shall be rejected or disallowed by any party unless it has been shown that such Servicing Advance was not made in accordance with this Agreement.

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 servicing provisions contained in this Agreement shall supersede the servicing provisions contained in such other servicing agreement from and after the Closing Date, except that such other servicing agreement shall survive and govern with respect to excess servicing fees and termination without cause.  In addition, the Master Servicer hereby acknowledges that, to the extent the Master Servicer or any 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 Mortgage Loan by any Person shall be subject to, and shall in no way adversely affect, the rights of the owner of the servicing rights related to such Mortgage Loan.

With respect to each Mortgage Loan, the related Servicer (other than WMMSC) shall fully furnish, in accordance with the Fair Credit Reporting Act and its implementing regulations and any other applicable laws, 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, or as otherwise acceptable by Fannie Mae or Freddie Mac.

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 by the Trustee, on behalf of the Certificateholders and the Trustee, in its own name or in the name of any Sub-Servicer, when a Servicer or any Sub-Servicer, 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 Sub-Servicers.

(a)

The Non-Designated Mortgage Loans may be subserviced by a Sub-Servicer on behalf of the related Servicer in accordance with the servicing provisions of this Agreement; provided, that the Sub-Servicer must be 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 Sub-Servicer to perform any such servicing responsibilities on its behalf, but the use by such Servicer of the Sub-Servicer 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 Sub-Servicer 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 Sub-Servicer engaged by such Servicer from its own funds.

A Servicer shall not permit a Sub-Servicer to perform any servicing responsibilities hereunder with respect to the Non-Designated Mortgage Loans unless that Sub-Servicer first agrees in writing with such Servicer to deliver an 1123 Certificate, an Assessment of Compliance and an Accountant’s Attestation in such manner and at such times that permits that Servicer to comply with Sections 13.06, 13.07 and 13.08 of this Agreement.

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 Sub-Servicer, 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.

A Servicer shall not outsource one or more separate servicing functions hereunder with respect to the Non-Designated Mortgage Loans to any Subcontractor unless that Subcontractor first agrees in writing with such Servicer to deliver an Assessment of Compliance and an Accountant’s Attestation in such manner and at such times that permits that Servicer to comply with Sections 13.06, 13.07 and 13.08 of this Agreement.

Each Servicer may in connection with its duties as Servicer hereunder enter into transactions with any of its affiliates relating to the Non-Designated 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. Notwithstanding the preceding sentence, any such transaction between a Servicer and any of its affiliates shall not release such Servicer from any of its obligations hereunder and such Servicer shall remain responsible hereunder for all acts and omissions of such affiliate with respect to such Mortgage Loans serviced by it as fully as if such acts and omissions were those of such Servicer.  Any fees and expenses relating to such transaction between such Servicer and its affiliate that are not otherwise reimbursable to such Servicer pursuant to this Agreement shall be borne by the parties thereto and shall not be an expense or fee of the Trust, the Depositor, the Trustee, the Trust Administrator, the Seller or the Master 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 Sub-Servicer and arrange for any servicing responsibilities to be performed by a successor Sub-Servicer 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 or such Servicer shall, at its own cost and expense terminate the rights and responsibilities of its Sub-Servicer(s) 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 Sub-Servicer(s) 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 Sub-Servicer, Subcontractor or Outsourcer, or any reference herein to actions taken through the Sub-Servicer, the Subcontractor, the Outsourcer, or otherwise, the related Servicer shall not be relieved of its obligations to the Depositor, the Trust, 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 Sub-Servicer, Subcontractor or Outsourcer for indemnification of such Servicer by such Sub-Servicer, Subcontractor or Outsourcer, as applicable, and nothing contained in this Agreement shall be deemed to limit or modify such indemnification.

(d)

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 Sub-Servicer regardless of whether such payments are remitted by the Sub-Servicer to such Servicer.

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

(e)

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

SECTION 3.03.

Master Servicing by Master Servicer.

For and on behalf of the Certificateholders, the Master Servicer shall oversee and enforce the obligation of Wells Fargo, GreenPoint, SPS, Bank of America and UMS to service and administer the Wells Fargo Serviced Mortgage Loans, GreenPoint Serviced Mortgage Loans, SPS Serviced Mortgage Loans, Bank of America Serviced Mortgage Loans, and UMS 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 the Servicers (other than WMMSC) 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 the Servicers (other than WMMSC) and shall cause each Servicer (other than WMMSC) 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 pursuant to Section 3.05, the amount of the Compensating Interest Payment for the Master Servicer, with respect to each Mortgage Loan, for the related Prepayment Period, to the extent any of Wells Fargo, GreenPoint, SPS, Bank of America, UMS or the related Designated Servicer, as applicable, defaults in its obligation to make such Compensating Interest Payment.  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 (other than WMMSC) shall for any reason no longer be a Servicer hereunder and the Master Servicer shall for any reason no longer be Master Servicer hereunder (including, in each case, by reason of an Event of Default), then in each case, 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 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 Sections 2.02, 2.03 or 3.17 or (iv) deemed to have made any representations and warranties of the Master Servicer or such Servicer hereunder); (v) be obligated to perform any obligation of the Master Servicer or such Servicer under Section 13.06 or Section 13.08 with respect to any period of time during which the Trustee was not acting as the Master Servicer or Servicer).  Any such assumption shall be subject to Section 8.02.  Notwithstanding the foregoing, if the Trustee has become the successor to the Master Servicer or a Servicer hereunder, the Trustee may, if it shall be unwilling to so act, or shall, if it is unable to so act, appoint, or petition a court of competent jurisdiction to appoint, any established mortgage loan servicing institution, the appointment of which does not adversely affect the then current rating of the Certificates, as the successor to the Master Servicer or a Servicer hereunder in the assumption of all or any part of the responsibilities, duties or liabilities of the Master Servicer or such Servicer, as applicable, provided that such successor to the Master Servicer or such Servicer, as applicable, shall not be deemed to have made any representation or warranty as to any Mortgage Loan made by the Master Servicer or such Servicer, as applicable.  

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.

(a)

Continuously from the date of the Series Supplement 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 the 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 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 and provided further that such action does not cause an Adverse REMIC Event.  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.  

Consistent with the foregoing, in instances when a Non-Designated Mortgage Loan is in default or default is reasonably foreseeable (within the meaning of the REMIC Provisions), and if in the related Servicer’s determination, in accordance with Accepted Servicing Practices, such modification is not materially adverse to the interests of the Certificateholders (taking into account any estimated Realized Loss that might result absent such action), the related Servicer may modify the terms of such Non-Designated Mortgage Loan to (1) capitalize to the outstanding principal balance of such Non-Designated Mortgage Loan unpaid principal and interest and other amounts owing under such Non-Designated Mortgage Loan and, without duplication, unreimbursed Advances, unreimbursed Servicing Advances, unpaid Servicing Fees and related amounts due to the related Servicer; (2) defer such amounts to a balloon payment due on the final payment date of such Non-Designated Mortgage Loan; (3) extend the maturity of any such Non-Designated Mortgage Loan, but in no instance past the date on which the final payment is due on the latest maturing Mortgage Loan in the related Loan Group as of the Initial Cut-off Date; (4) reduce the related Mortgage Rate (provided that the Mortgage Rate of any fixed-rate Mortgage Loan may not be reduced, and the Mortgage Rate of any adjustable rate Mortgage Loan may not be reduced below the Mortgage Rate of such Mortgage Loan immediately prior to the related first adjustment date); (5) accept less than the outstanding principal balance as satisfaction of such Mortgage Loan; and/or (6) reduce the outstanding principal balance of such Non-Designated Mortgage Loan; provided, however, that the related Servicer shall be obligated, if so directed by the Modification Oversight Agent (who shall notify the Master Servicer when it directs a Servicer), to obtain the consent of the Modification Oversight Agent prior to taking such action, unless such action is required by applicable law.

To the extent a Servicer is required to obtain the consent of the Modification Oversight Agent prior to any modification, it shall submit to the Modification Oversight Agent any information the Modification Oversight Agent requires, in such form as the Modification Oversight Agent shall reasonably request, or in such form as may be mutually agreed upon between such Servicer and the Modification Oversight Agent, with respect to each Mortgage Loan subject to a proposed modification.  The Modification Oversight Agent will notify such Servicer in writing (with a copy to the Master Servicer) of its consent or objection to any requested modification.

The Modification Oversight Agent acknowledges that it may, in the course of performing its responsibilities under this Agreement, be exposed to or acquire information concerning the Mortgage Loans and the related Mortgagors that may be furnished orally, electronically or in writing by the related Servicer, for the purpose of reviewing the modification of a Mortgage Loan, which information constitutes “nonpublic personal information” within the meaning of the Gramm-Leach-Bliley Act of 1999; nonpublic financial, business, scientific, and technical information of such Servicer (including but not limited to patterns, plans, compilations, program devices, formulas, designs, methods, techniques, processes, procedures, programs), which information is proprietary or confidential to the Servicer (collectively, “Confidential Information”).  The Modification Oversight Agent agrees to hold the Confidential Information in strict confidence and not use any Confidential Information of any Servicer (i) other than in connection with its obligations under this Agreement; (ii) for its own benefit; (iii) for the benefit of any third party; or (iv) to such Servicer’s detriment.  The Modification Oversight Agent may disclose Confidential Information to its employees or agents (collectively, “Representatives”) who have a need to know such information in connection with the performance of the Modification Oversight Agent’s obligations under this Agreement, provided that the Modification Oversight Agent advises its Representatives exposed to such Confidential Information of their obligation to keep such information confidential.

(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 [Name of Series Trust]” or, if established and maintained by a Sub-Servicer on behalf of a Servicer, “[Sub-Servicer’s name], in trust for [Servicer’s name]” or “[Sub-Servicer’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 Sub-Servicer employs a Sub-Servicer, the Collection Account shall be titled “[name of Sub-Servicer’s sub-servicer], in trust for [Sub-Servicer’s name].”  Each Collection Account maintained by each Servicer (other than Wells Fargo), shall be an Eligible Account acceptable to the Depositor and the Trust Administrator.  Each Collection Account maintained by Wells Fargo shall be an Eligible Account.  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 into a clearing account on a daily basis and into the applicable Collection Account within two Business Days of receipt, unless otherwise indicated, and retain therein, the following collections remitted by Sub-Servicers 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 (including amounts deposited pursuant to Section 3.09(c)(C)) adjusted to the per annum rate equal to the Mortgage Rate reduced by the related Expense Fee Rate, as applicable

(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)(ix) 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 Loan pursuant to Section 3.11;

(viii)

all Assigned Prepayment Premiums, if applicable, on the related Non-Designated Mortgage Loans to the extent such Assigned Prepayment Premiums have not been waived in accordance with Section 3.21;

(ix)

all Recoveries on the related Non-Designated Mortgage Loans; and

(x)

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 any other amounts owed to such Servicer pursuant to Section 3.14 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 Lender Paid 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 3.05.  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)

pursuant to Section 3.08(a)(ix), (a) the aggregate amount remitted by each Servicer of Non-Designated Mortgage Loans to the Trust Administrator, including any Assigned Prepayment Premiums and (b) the aggregate amount remitted by each Designated Servicer to the Master Servicer or Trust Administrator pursuant to their respective Designated Servicing Agreements, in each case including any related prepayment premiums if so required to be remitted;

In the event that the Master Servicer or a Servicer shall remit to the Trust Administrator any amount not required to be remitted, the Master Servicer or such Servicer, as applicable, may at any time direct the Trust Administrator to withdraw such amount from the Certificate Account, any provision herein to the contrary notwithstanding.  Such direction may be accomplished by delivering an Officer’s Certificate to the Trust Administrator which 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, a Prefunding Account, a Capitalized Interest Account or the Certificate 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 Depositor or the Trust Administrator, 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 or a Capitalized Interest 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 a Prefunding Account, the Business Day immediately preceding a Subsequent Transfer Date or on the Subsequent Transfer Date if the invested funds are managed or advised by the Trust Administrator or its affiliates.  All income and gain net of any losses realized from any such balances or investment of funds on deposit in a Collection Account shall be for the benefit of the related Servicer as servicing compensation and shall be remitted to it monthly as provided herein.  The amount of any realized losses in a Collection Account incurred in any such account in respect of any such investments shall promptly be deposited by the related Servicer (from its own funds) in the related Collection Account.  Neither the Trustee nor the Trust Administrator shall be liable for the amount of any loss incurred in respect of any investment or lack of investment of funds held in a Collection Account, any Prefunding Account or any Capitalized Interest Account and made in accordance with this Section 3.05. All income and gain net of any losses realized from any such investment of funds on deposit in the Certificate Account shall be for the benefit of the Trust Administrator as compensation and shall be remitted to it monthly as provided herein.  The amount of any realized losses in the Certificate Account incurred in any such account in respect of any such investments shall promptly be deposited by the Trust Administrator (from its own funds) in the Certificate Account.  The Depositor shall direct the Trust Administrator in writing as to the investment of amounts in any Prefunding Account or Capitalized Interest Account.  All income and gain net of any losses realized from any such balances or investment of funds on deposit in a Prefunding Account or Capitalized Interest Account shall be for the benefit of the Depositor and shall be remitted to it monthly.  The amount of any net investment losses in a Prefunding Account or Capitalized Interest Account shall promptly be deposited by the Depositor (from its own funds) in such Prefunding Account or Capitalized Interest Account, as applicable.

(f)

Each Servicer, other than Wells Fargo, shall give notice to the Trustee, the Trust Administrator, the Seller, each Rating Agency and the Depositor of any proposed change of the location of the related Collection Account prior to any change thereof.  Wells Fargo shall give notice to the Depositor of any proposed change of the location of the related Collection Account prior to any change thereof and, upon receipt of such notice, the Depositor shall give notice to the Trustee, the Trust Administrator, the Seller and each Rating Agency.  The Trust Administrator shall give notice to the Master Servicer and each Servicer, the Seller, each Rating Agency, the Trustee and the Depositor of any proposed change of the location of the Certificate Account prior to any change thereof.

(g)

The Trust Administrator shall establish and maintain, on behalf of the Certificateholders, each Prefunding Account.  On the Closing Date, the Depositor shall remit the related Prefunded Amount to the Trust Administrator for deposit in a Prefunding Account.  On each Subsequent Transfer Date, upon satisfaction of the conditions for such Subsequent Transfer Date set forth in Sections 2.01(f) and (g), 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 a Prefunding Account on the Distribution Date immediately following the end of the related Prefunding Period, to the extent that they represent earnings on the amounts originally deposited into such Prefunding Account, the Trust Administrator shall distribute them to the order of the Depositor.  The remaining funds, other than any investment earnings, shall be transferred to the Certificate Account to be included as part of principal distributions to the related Certificates on such Distribution Date.

(h)

The Trust Administrator shall establish and maintain, on behalf of the Certificateholders, each Capitalized Interest Account.  On the Closing Date, the Depositor shall remit the Capitalized Interest Deposit to the Trust Administrator for deposit in the related Capitalized Interest Account.  On the Business Day prior to the first three Distribution Dates, the Trust Administrator shall transfer from the Capitalized Interest Account to the Certificate Account an amount equal to the Capitalized Interest Distribution for such Distribution Date and the Trust Administrator shall transfer from the Capitalized Interest Account to the Depositor, an amount equal to the Capitalized Interest Release Amount for such Distribution Date.

In the event that a Sub-Servicer employs a sub-servicer, the Escrow Accounts shall be titled “[name of Sub-Servicer’s sub-servicer] in trust for [Sub-Servicer’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. To the extent required by law, the applicable Servicer shall pay interest on escrowed funds to the Mortgagor notwithstanding that the Escrow Account may be non interest bearing or that interest paid thereon is insufficient for such purposes.

(d)

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

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 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 such Servicer.  In addition, each Servicer (other than WMMSC) shall provide to the Special Servicer reasonable access to all records and documentation regarding the Non-Designated Mortgage Loans serviced by it that become Special Serviced Mortgage Loans.

(b)

Each Servicer, separately with respect to the Non-Designated Mortgage Loans each directly services, shall inspect the related Mortgaged Properties as often as deemed necessary by such Servicer in such party’s sole discretion, to assure itself that the value of such Mortgaged Property is being preserved.  In addition, if any Non-Designated Mortgage Loan is more than 60 days delinquent (under the “MBA” method), such Servicer, as applicable, shall conduct subsequent inspections in accordance with Accepted Servicing Practices or as may be required by the primary mortgage guaranty insurer.  In addition, if any Non-Designated Mortgage Loan is more than 60 days delinquent (under the "MBA" method) such Servicer, other than Bank of America, shall obtain a broker price opinion with respect thereto and communicate the value of such Non-Designated Mortgage Loan as required under Exhibit H-1 unless the related Servicer has reason to believe that the payment of the delinquent amounts is immediately forthcoming.  Notwithstanding the foregoing, Wells Fargo, in its capacity as Servicer, shall not be required to obtain a broker price opinion unless the related Non-Designated Mortgaged Loan is delinquent by 120 days (provided, however, that if such loan is performing under a repayment plan or an arrangement that is a precondition to modifying the related loan (a "stipulation to modification") Wells Fargo, as Servicer, shall not be required to obtain a broker price opinion) or, if such related Non-Designated Mortgaged Loan is in foreclosure, within fifteen days of such foreclosure.  Each Servicer shall keep a written or electronic report of each such inspection.

(iii)

to reimburse such Servicer for any Nonrecoverable Advance previously made or any amount expended pursuant to Section 3.11(a);

(iv)

to reimburse such Servicer for (A) unreimbursed Servicing Advances or such Servicer’s right to reimbursement pursuant to this clause (A) with respect to any Non-Designated Mortgage Loan being limited to amounts received on such Non-Designated Mortgage Loan which represent late payments of principal and/or interest (including, without limitation, Liquidation Proceeds and Insurance Proceeds with respect to such Non-Designated Mortgage Loan) respecting which any such advance was made and (B) for unpaid Servicing Fees as provided in Section 3.11;

(xi)

on or prior to the Cash Remittance Date preceding each Distribution Date, each Servicer shall withdraw an amount equal to the sum of all Assigned Prepayment Premiums received during the related Prepayment Period applicable to the Mortgage Loans serviced by such Servicer, and remit such amount to the Trust Administrator for deposit in the Certificate Account;

(xii)

to clear and terminate such Collection Account upon termination of this Agreement pursuant to Section 11.01; and

(xiii)

to reimburse such Servicer for any Capitalization Reimbursement Amounts not previously reimbursed.

Each Servicer shall keep and maintain separate accounting, on a Non-Designated 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) for reimbursement 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.

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).  In addition, the Trust Administrator may from time to time make withdrawals from the Certificate Account for the following purposes:

to pay to itself the Trust Administrator Total Fees, if any, to which it is entitled pursuant to Section 10.05 for the related Distribution Date, and to pay to itself, the Master Servicer or any Custodian any other amounts in respect of reimbursement of costs, expenses, indemnification or other amounts to which it, the Master Servicer or any Custodian is entitled to reimbursement or payment under the terms of this Agreement or the Custodial Agreement;

(ii)

to withdraw and return to the Master Servicer or the applicable Servicer for deposit to the applicable Collection Account any amount deposited in the Certificate Account and not required to be deposited therein; and

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 such 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 use reasonable efforts to 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 related 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 related 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; provided, however, that the limitations contained in this sentence shall not apply to modifications made pursuant to Section 3.05(a).  Such costs shall constitute a Servicing Advance and will be reimbursable to the related Servicer to the extent permitted by Section 3.08.  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)

(A) Unless otherwise required in accordance with applicable state and federal law relating to the cancellation of, or collection of premiums for mortgage guaranty insurance, with respect to each Non-Designated Mortgage Loan with a Loan-to-Value Ratio in excess of 80% which the Seller represented to be covered by a Mortgagor Paid Mortgage Guaranty Insurance Policy as of the Closing 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 Mortgagor Paid 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 Mortgagor Paid 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 Mortgagor Paid Mortgage Guaranty Insurance Policy.  If the insurer shall cease to be a Qualified Insurer, the related Servicer shall determine whether recoveries under the Mortgagor Paid 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 Mortgagor Paid 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 Mortgagor Paid 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 Mortgagor Paid Mortgage Guaranty Insurance Policy, if any, of such assumption or substitution of liability in accordance with the terms of such Mortgagor Paid 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 Mortgagor Paid Mortgage Guaranty Insurance Policy, provided that such required actions are in compliance with all applicable law.  If such Mortgagor Paid Mortgage Guaranty Insurance Policy is terminated as a result of such assumption or substitution of liability, the related Servicer shall obtain a replacement Mortgagor Paid 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.

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 any such Non-Designated Mortgage Loan are not sufficient to pay the premiums on the related Mortgagor Paid Mortgage Guaranty Insurance Policy, the applicable Servicer shall effect timely payment of such premiums, and such costs shall be recoverable by such Servicer from the related Liquidation Proceeds or otherwise as a Servicing Advance pursuant to Section 3.08(a).

(B) With respect to each Non-Designated Mortgage Loan which the Seller represented to be covered by a Lender Paid Mortgage Guaranty Insurance Policy as of the Closing Date, the applicable Servicer shall effect timely payment of the premiums on such Lender Paid 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.  The related Servicer shall not take any action which would result in noncoverage under any applicable Lender Paid Mortgage Guaranty Insurance Policy of any loss which, but for the actions of such Servicer would have been covered thereunder.  

In the event that an insurer under a Lender Paid Mortgage Guaranty Insurance Policy is in default under the related Lender Paid Mortgage Guaranty Insurance Policy and the Servicer is no longer required to pay premiums to such insurer or in the event that the Servicer shall terminate such Lender Paid Mortgage Guaranty Insurance Policy pursuant to this clause (c) because such insurer is no longer a Qualified Insurer, the Servicer shall not replace the related insurer with a Qualified Insurer unless the premium payable to such Qualified Insurer is equal to, or less than, the premium payable to the replaced insurer without written direction from the Trust Administrator, the Trustee or the Master Servicer that the consent of each Certificateholder affected thereby has been obtained.  In no event shall a Servicer, the Depositor, the Trustee, the Trust Administrator (unless so directed by a Certificateholder in accordance with the terms hereof) or the Master Servicer be required to obtain such Certificateholder consent.

(C) In the event that any Non-Designated Mortgage Loan had a Lender Paid Mortgage Guaranty Insurance Policy in effect as of the related Closing Date and such Lender Paid Mortgage Guaranty Insurance Policy ceases to be in effect and the Servicer is no longer obligated to pay premiums to an insurer under a related Lender Paid Mortgage Guaranty Insurance Policy because  (a) the related insurer has rescinded the insurance coverage with respect to a Non-Designated Mortgage Loan because such Non-Designated Mortgage Loan did not comply with the terms of the related Lender Paid Mortgage Guaranty Insurance Policy, (b) such insurer is in default thereunder and the Servicer has be unable to replace such insurer with a Qualified Insurer pursuant to the provisions of this Agreement, or (c) the related insurer ceases to be a Qualified Insurer and the Servicer has be unable to replace such insurer with a Qualified Insurer pursuant to the provisions of this Agreement,  the Servicer shall (i) deposit any premiums that would otherwise be due to any such insurer into the Collection Account pursuant to clause 3.05(c)(ii) and (ii) identify any such amounts in each monthly statement prepared in connection with Exhibit H-1 hereto.  Notwithstanding the foregoing, Wells Fargo, in its capacity as Servicer, shall have no obligation to comply with clause (ii) of the previous sentence.  In the event that the Servicer has replaced any insurer under a Lender Paid Mortgage Guaranty Insurance Policy with a Qualified Insurer and the premium payable to such Qualified Insurer is at a rate lower than the rate payable to the replaced insurer, the Servicer shall deposit the difference between the amount payable to the replaced insurer and the Qualified Insurer into the Collection Account pursuant to the terms of the second preceding sentence (any such amounts deposited pursuant to this sentence and the second preceding sentence are collectively referred to as the "Unused MI Premiums").  Neither the Master Servicer nor the Trust Administrator shall have any obligation to confirm, verify or reconcile any amounts deposited into the Certificate Account with respect to LPMI premiums pursuant to this Section 3.09(c)(C).  The Master Servicer and Trust Administrator shall be entitled to rely upon information reported by the Servicers and the Designated Servicers related to such premiums.  Neither the Master Servicer nor the Trust Administrator shall have any liability to Certificateholders or otherwise for any incomplete or inaccurate reporting or remittances by any Servicer or Designated Servicer, or any Servicer’s or Designated Servicer’s failure to remit or report any such premiums.

(d)

In connection with its activities as servicer, each Servicer shall prepare and present, on behalf of itself, the Depositor, the Trust, 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. In the event that a Mortgage Loan is subject to pool insurance and the Servicer has been notified of such coverage, the Servicer agrees to prepare and present claims to the related insurer and to take such other actions as shall be necessary in accordance with Accepted Servicing Practices to permit recovery under any such insurance policies. Pursuant to Section 3.05(c), any amounts collected by the Servicer under any pool insurance policy shall be deposited in the Custodial Account, subject to withdrawal pursuant to Section 3.08(a). In the event that the Servicer is not notified of existing or subsequently acquired pool insurance coverage, the Servicer shall be under no obligation to pursue any claims or to take any other action related to such coverage.

(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 3.10 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 related 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 shall be retained by such Servicer as additional servicing compensation.

SECTION 3.11.

Realization Upon Defaulted 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 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 by 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) .  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), and such Servicer shall have no further obligation to service such Non-Designated Mortgage Loan under the provisions of this Agreement.

(b)

In the event that title to a Mortgaged Property is acquired in foreclosure or by deed in lieu of foreclosure, the deed or certificate of sale shall be taken (pursuant to a limited power of attorney to be provided by the Trustee to the Servicer) in the name of the Trustee or a nominee thereof, on behalf of the Certificateholders, or in the event the Trustee or a nominee thereof notifies the related Servicer that the Trustee or such nominee is not authorized or permitted to hold title to real property in the state where the REO Property is located, or would be adversely affected under the “doing business” or tax laws of such state by so holding title, the deed or certificate of sale shall be taken in the name of such Person or Persons as shall be identified by the Trustee consistent with an Opinion of Counsel obtained by the Trustee from an attorney duly licensed to practice law in the state where the REO Property is located.  Any Person or Persons holding such title other than the Trustee shall acknowledge in writing that such title is being held as nominee for the benefit of the Trustee.  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 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 and filing such tax and information returns as may be required, in the form required, 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 shall 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 Non-Designated 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 Non-Designated 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 Non-Designated Mortgage Loan.

(e)

The proceeds from any liquidation of a Non-Designated Mortgage Loan, as well as any income from a related 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, and with respect to Wells Fargo, any REO Disposition Fees related to such Mortgage Loan; 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 Expense Fee Rate, to the Due Date occurring in the month in which such amounts are required to be distributed; and fifth, as a recovery of principal of the Mortgage Loan.  Excess Proceeds shall be retained by the related Servicer as additional servicing compensation pursuant to Section 3.14.

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 shall immediately notify the related Custodian by delivering, or causing to be delivered a “Request for Release” substantially in the form of Exhibit K.  Upon receipt of such request, such 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 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 such 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 related Custodian within three Business Days of delivery to such Custodian of a Request for Release in the form of Exhibit K 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 related Custodian on its behalf, 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 Trustee, or the related Custodian a Request for Release in the form of Exhibit K, 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 of a Servicer to be Held for the Trust.

Notwithstanding any other provisions of this Agreement, each Servicer shall transmit to the related 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 Trustee, or such Custodian on its behalf, 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 also agrees that it shall not create, incur or subject any Mortgage File or any funds that are deposited in the related Collection Account, Certificate Account or any related Escrow Account, or any funds that otherwise are or may become due or payable to the 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 Fee; Indemnification of Master Servicer.

(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 Non-Designated Mortgage Loans, the amount of its Servicing Fee, for each Mortgage Loan serviced by it, less any amounts in respect of its Servicing Fee, as applicable, 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).  In connection with the servicing of any Special Serviced Mortgage Loan, the Special Servicer shall receive the Servicing Fee for such Special Serviced Mortgage Loan as its compensation and Ancillary Income with respect to Special Serviced Mortgage Loans.

(b)

With respect to each Non-Designated Mortgage Loan, additional servicing compensation in the form of Ancillary Income shall be retained by the related Servicer (in the case of Payoff Interest, to the extent not required to make payments in respect of Compensating Interest Payments).  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 3.16) and shall not be entitled to reimbursement thereof except as specifically provided for in this 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 any such Mortgage Loan that is delinquent (under the “MBA” method) and will contain provisions for the deposit of cash with such Servicer by such 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 any such Mortgage Loan that is delinquent (under the “MBA” method) 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 (as a Sub-Servicer on behalf of the related Servicer) with respect to any such Mortgage Loan that is delinquent (under the “MBA” method) so long as (A) such Holder meets the requirements for a Sub-Servicer set forth in Section 3.02(a), (B) such Holder has a current special servicing ranking of at least “Average” from S&P, (C) such Holder shall subservice such Mortgage Loan in accordance with this Agreement, and (D) the related Servicer has the right to transfer such servicing rights without the payment of any compensation to a Sub-Servicer.

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 any 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 such Designated Servicing Agreement.  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.

(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.

Assigned Prepayment Premiums.

(a)

Notwithstanding anything in this Agreement to the contrary, in the event of a Principal Prepayment, the applicable Servicer may not waive any Assigned Prepayment Premium or portion thereof required by the terms of the related Mortgage Note unless (i) the related Mortgage Loan is in default or foreseeable default and such waiver (a) is standard and customary in servicing mortgage loans similar to the Mortgage Loans and (b) would, in the reasonable judgment of such Servicer, maximize recovery of total proceeds taking into account the value of such Assigned Prepayment Premium and the related Mortgage Loan, (ii) (A) the enforceability thereof is limited (1) by bankruptcy, insolvency, moratorium, receivership, or other similar law relating to creditors’ rights generally or (2) due to acceleration in connection with a foreclosure or other involuntary payment, or (B) the enforceability is otherwise limited or prohibited by applicable law, (iii) the enforceability would be considered “predatory” pursuant to written guidelines issued by any applicable federal, state or local authority having jurisdiction over such matters, (iv) such Servicer is unable to locate documentation sufficient to allow it to confirm the existence and amount of such Assigned Prepayment Premium after using commercially reasonable efforts to locate such documentation, which efforts shall include, but are not limited to, seeking such documentation from the Depositor, the Seller, the related Custodian and from its own records or files, (v) the related Mortgaged Property has been damaged such that the current value of the Mortgaged Property has been reduced by at least half as a result of a natural disaster or other insured or uninsured peril, and the borrower has elected to pay the loan in full rather than rebuild the Mortgaged Property, or (vi) with respect to SPS Serviced Mortgage Loans, SPS may waive Assigned Prepayment Premiums in connection with any refinancing of such Mortgage Loans by SPS or an affiliate thereof.  For the avoidance of doubt, the applicable Servicer may waive an Assigned Prepayment Premium in connection with a short sale or short payoff on a defaulted Mortgage Loan.  If an applicable Servicer has waived all or a portion of an Assigned Prepayment Premium relating to a Principal Prepayment, other than as provided above, such Servicer shall deliver to the Trust Administrator no later than the next succeeding Cash Remittance Date, for deposit into the Certificate Account, the amount of such Assigned Prepayment Premium (or such portion thereof as had been waived) for distribution in accordance with the terms of this Agreement, and if such Servicer fails to deliver such amount, any of the Trust Administrator, the Master Servicer, the Trustee or the Seller may enforce such obligation of such Servicer to make such payment.  If such Servicer has waived all or a portion of an Assigned Prepayment Premium for any reason, it shall include such information, including the reason for such waiver, in any monthly reports it provides, and such Servicer if other than Wells Fargo, shall notify the Trust Administrator, the Seller, the Master Servicer and the Trustee of such waiver, and if such Servicer is Wells Fargo, Wells Fargo shall notify the Trust Administrator and the Trust Administrator shall forward any such notice to the Seller, the Master Servicer and the Trustee.  Notwithstanding any provision in this Agreement to the contrary, in the event the Assigned Prepayment Premium payable under the terms of the related Mortgage Note is less than the amount of the Assigned Prepayment Premium set forth in the Mortgage Loan Schedule or other information provided to the applicable Servicer, such Servicer shall not have any liability or obligation with respect to such difference.  The Master Servicer shall not have any responsibility for verifying the accuracy of the amount of Assigned Prepayment Premiums remitted by the Servicers.

(b)

Notwithstanding anything in this Agreement to the contrary, the Trustee and the Trust Administrator shall have no obligation to collect Prepayment Premiums from any Servicer or Designated Servicer other than Wells Fargo, in its capacity as a Servicer, GreenPoint, SPS, Bank of America or UMS.

(c)

Notwithstanding anything in this Agreement to the contrary, to the extent that a Servicer becomes the owner of the Prepayment Premium with respect to any Mortgage Loan, each Holder of a Class P Certificate hereby agrees that such Holder’s right to receive Prepayment Premiums collected by such Servicer in connection with the Principal Prepayment of any of such Mortgage Loans or amounts deposited therein pursuant to this Section 3.21 shall be extinguished in full.

SECTION 5.01.

Advances by the Trust Administrator, 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 Servicing Fee Rate) which were due on such Non-Designated Mortgage Loans serviced by it during the applicable Collection Period and which were delinquent (under the “MBA” method) at the close of business on the immediately preceding Determination Date; provided, however, that with respect to any Balloon Loan that is delinquent on its maturity date, a Servicer shall not be required to advance the related balloon payment but shall be required to continue to make Advances in accordance with this Section 5.01 with respect to such Balloon Loan in an amount equal to (a) for each Servicer other than WMMSC, an assumed scheduled payment that would otherwise be due based on the original amortization schedule for that Mortgage Loan (with interest at the Mortgage Rate less the Servicing Fee Rate) and (b) for WMMSC, one month’s interest on the outstanding principal balance at the applicable Mortgage Rate, in each case to the extent the related Servicer deems such amount to be recoverable.  Each Servicer’s obligation to make such Advances as to any related Non-Designated Mortgage Loan shall 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 the related Servicer, been completely liquidated.  Each Servicer shall not 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, 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.

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 make 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 WMMSC Serviced Mortgage Loan, if the amount of Advances received from WMMSC is less than the amount required to be advanced by WMMSC, the Trust Administrator shall be obligated to make a payment in an amount equal to such deficiency, subject to any determination by the Trust Administrator that any portion of the amount required to be advanced is a Nonrecoverable Advance.

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 or from other funds in such Collection Account being held for future distribution at that time.

Subject to Section 11.03 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 of the Series Supplement.

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 or any transfer of a Private Certificate from the Depositor or an affiliate of the Depositor to an owner trust or other entity established by the Depositor, 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 and such Certificateholder’s prospective transferee shall each certify to the Trust Administrator in writing the facts surrounding the transfer in substantially the form set forth in Exhibit L (the “Transferor Certificate”) and (i) deliver a letter in substantially the form of either (A) Exhibit M-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, (B) Exhibit M-2 (the “Rule 144A Letter”) or (C) Exhibit M-3 (the “Regulation S 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.  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) or Regulation S, as applicable, for transfer of any such Certificate without registration thereof under the 1933 Act pursuant to the registration exemption provided by Rule 144A or Regulation S.  In the event the representations referred to in this Section 6.02(e) are not furnished because the related Certificates are Book-Entry Certificates, such representations shall be deemed to have been made to the Trust Administrator by the transferee’s acceptance of such Certificate by any beneficial owner who purchases an interest in such Certificate if such Certificate is a Book Entry Certificate. The Trust Administrator shall cooperate with the Depositor in providing the 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, the Seller, the Master Servicer, each Servicer, the Special Servicer and the Modification Oversight Agent 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)

Except in connection with any transfer of a Private Certificate by the Depositor to any affiliate or any transfer of a Private Certificate from the Depositor or an affiliate of the Depositor to an owner trust or other entity established by the Depositor, no transfer of an ERISA-Restricted Certificate (except for the Residual Certificates) shall be made unless the Trust Administrator shall have received in accordance with Exhibit M-1, Exhibit M-2 or Exhibit M-3, 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 arrangement subject to Section 406 of ERISA or Section 4975 of the Code, or a person using the assets of any such plan or arrangement, which representation letter shall not be an expense of the Trustee, 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 arrangement subject to Section 406 of 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 Trust Administrator 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 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.  No transfer of a Residual Certificate shall be made unless the Trust Administrator shall have received, in accordance with Exhibit N, 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 arrangement subject to Section 406 of ERISA or Section 4975 of the Code, or a person using the assets of any such plan or arrangement, which representation letter shall not be an expense of the Trustee, the Trust Administrator or the Trust Fund.  In the event the representations referred to in this Section 6.02(f) are not furnished because the related Certificates are Book-Entry Certificates, such representations shall be deemed to have been made to the trustee by the transferee’s acceptance of such ERISA-Restricted Certificate by any beneficial owner who purchases an interest in such Certificate if such Certificate is a Book-Entry Certificate.  In the event that a representation is violated, or any attempt to transfer an ERISA-Restricted Certificate to a plan or 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 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 N) 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 shall 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 O, 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 O.

(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 O 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 or the related Servicer from such Person.

(v)

The provisions of this Section 6.02(g) set forth prior to this Section 6.02(g)(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 DEPOSITOR 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.

(i)

Each Holder of a Swap Certificate or any interest therein shall be deemed to have represented, by its acquisition or holding of such certificate or any interest therein, that as of any date prior to the termination of the Swap Agreement, at least one of PTCE 84-14, 90-1, 91-38, 95-60 or 96-23 or other applicable exemption applies to such Holder’s right to receive payments from the Supplemental Interest Trust.

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 protected 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, DLJMC 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 shall 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 shall 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, with the consent of the applicable Participants, 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 and the applicable Participants consent, 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 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.

None of the Depositor, the Master Servicer, any Servicer, the Seller, the Special Servicer or the Modification Oversight Agent shall be under any obligation to appear in, prosecute or defend any legal action that is not incidental to its respective duties hereunder and which in its opinion may involve it in any expense or liability; provided, however, that any of the Depositor, the Master Servicer, any Servicer, the Seller, the Special Servicer or the Modification Oversight Agent may in its discretion undertake any such action that it may deem necessary or desirable in respect of this Agreement and the rights and duties of the parties hereto and interests of the Trustee, the Trust Administrator and the Certificateholders hereunder.  In such event, the legal expenses and costs of such action and any liability resulting therefrom shall be expenses, costs and liabilities of the Trust Fund, and the Depositor, the Master Servicer, any Servicer, the Seller, the Special Servicer and the Modification Oversight Agent, as applicable, shall be entitled to be reimbursed therefor from the Trust Fund.  The right of each Servicer and the Modification Oversight Agent to indemnity and reimbursement pursuant to this Section 7.03 shall survive the resignation or termination of such Servicer as set forth herein.

(c)

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

(a)

None of the Master Servicer, any Servicer, the Special Servicer or the Modification Oversight Agent shall resign from the obligations and duties hereby imposed on it except (i) upon appointment of a successor master servicer, successor servicer, successor special servicer or successor modification oversight agent and receipt by the Trustee and the Trust Administrator of a letter from each Rating Agency that such a resignation and appointment will not result in a downgrading of the rating of any of the Certificates related to the applicable Mortgage Loans, or (ii) upon determination that its duties hereunder are no longer permissible under applicable law.  Any such determination under clause (ii) permitting the resignation of the Master Servicer, a Servicer, the Special Servicer or the Modification Oversight Agent shall be evidenced by an Opinion of Counsel to such effect delivered to the Trustee and the Trust Administrator.  No such resignation shall become effective until the successor master servicer, successor servicer, successor special servicer or successor modification oversight agent shall have assumed the Master Servicer’s, such Servicer’s, the Special Servicer’s or the Modification Oversight Agent’s, as applicable, responsibilities, duties, liabilities and obligations hereunder which, in the case of the Master Servicer or a Servicer, shall be in accordance with Section 8.02.

Notwithstanding the foregoing, in the event that the Master Servicer is appointed as the successor servicer to SPS, the requirements of Section 7.04(a)(i) shall be waived.

(c)

Notwithstanding the foregoing, if the Trust Administrator shall for any reason no longer be Trust Administrator hereunder, at DLJMC’s request, the Master Servicer shall resign, upon the selection and appointment of a successor master servicer; provided that DLJMC delivers to the Trustee and the Trust Administrator the letter required in Section 7.04(a)(i) above.

(d)

Notwithstanding the foregoing, at DLJMC’s request, the Special Servicer shall resign, upon the selection and appointment of a successor special servicer by DLJMC; provided that DLJMC delivers to the Trustee and the Trust Administrator the letter required in Section 7.04(a)(i) above.

(e)

Notwithstanding the foregoing, at DLJMC’s request, the Modification Oversight Agent shall resign, upon the selection and appointment of a successor modification oversight agent by DLJMC; provided that DLJMC delivers to the Trustee and the Trust Administrator the letter required in Section 7.04(a)(i) above.

SECTION 7.05.

Each of the Master Servicer, the Seller, the Special Servicer, the Modification Oversight Agent and each Servicer in its individual or any other capacity may become the owner or pledgee of Certificates with the same rights as it would have if it were not the Master Servicer, the Seller, the Special Servicer, the Modification Oversight Agent or a Servicer.

If an Event of Default due to the actions or inaction of the Master Servicer, the Modification Oversight Agent or a Servicer described in clauses (a) through (f) and (l) of this Section 8.01 shall occur, then, and in each and every such case, so long as such Event of Default shall not have been remedied, (i) the Trust Administrator shall at the direction of DLJMC, the Trustee or the Holders of Certificates evidencing not less than 25% of the Voting Rights evidenced by the Certificates, by notice in writing to the Master Servicer, the Modification Oversight Agent or such Servicer (with a copy to the Rating Agencies), terminate all of the rights and obligations of the Master Servicer, the Modification Oversight Agent or such Servicer under this Agreement (other than rights to reimbursement for Advances and Servicing Advances previously made, as provided in Section 3.08), (ii) the Master Servicer may, if such Event of Default is due to the actions or inactions of a Servicer (other than WMMSC), by notice in writing to such Servicer (with a copy to the Rating Agencies), terminate all of the rights and obligations of such Servicer (other than WMMSC) under this Agreement (other than rights to reimbursement for Advances and Servicing Advances previously made, as provided in Section 3.08) and (iii) the Trust Administrator may, if such Event of Default is due to the actions or inactions of WMMSC, by notice in writing to WMMSC (with a copy to the Rating Agencies), terminate all of the rights and obligations of WMMSC under this Agreement (other than rights to reimbursement for Advances and Servicing Advances previously made, as provided in Section 3.08).

If an Event of Default described in clause (g) shall occur, (i) if the Master Servicer has failed to make any Advance, the Trustee, (ii) if WMMSC has failed to make any Advance, the Trust Administrator, and (iii) if any Servicer (other than WMMSC) has failed to make any Advance, the Master Servicer, shall prior to the next Distribution Date, immediately make such Advance and terminate the rights and obligations of the Master Servicer or applicable Servicer, as applicable, hereunder and succeed to the rights and obligations of the Master Servicer or such Servicer, as applicable, hereunder pursuant to Section 8.02, including the obligation to make Advances on such succeeding Distribution Date pursuant to the terms hereof.  No Event of Default with respect to the Master Servicer or a Servicer shall affect the rights or duties of any other Servicer or constitute an Event of Default as to any other Servicer.

If an Event of Default described in clause (h), (i) or (k) occurs, (i) if the Event of Default relates to WMMSC, the Trust Administrator, and (ii) if the Event of Default relates to any Servicer other than WMMSC, the Master Servicer, shall at the direction of DLJMC, by notice in writing to such Servicer, terminate all of the rights and obligations of such Servicer under this Agreement (other than rights to reimbursement for Advances and Servicing Advances previously made, as provided in Section 3.08) and shall appoint as successor Servicer the entity selected by DLJMC; provided, however,  that if no such entity is selected by DLJMC, DLJMC shall not terminate any such rights unless the Master Servicer agrees to succeed to the rights and obligations of such Servicer hereunder pursuant to Section 8.02, including the obligation to make Advances on such succeeding Distribution Date pursuant to the terms hereof; and provided further, that DLJMC shall first furnish to the Trust Administrator and the Master Servicer a letter from each Rating Agency that the appointment of such successor will not result in a downgrading of the rating of any of the Certificates.

No Event of Default with respect to the Servicer shall affect the rights or duties of the Master Servicer or constitute an Event of Default as to the Master Servicer.

SECTION 8.02.

Master Servicer or Trust Administrator to Act; Appointment of Successor.

On and after the time the Master Servicer or a Servicer receives a notice of termination pursuant to Section 8.01 or resigns pursuant to Section 7.04, subject to the provisions of Sections 3.04 and 8.01, the Trustee (in the case of the Master Servicer), the Trust Administrator (in the case of WMMSC), or the Master Servicer (in the case of any Servicer other than WMMSC) shall be the successor in all respects to the Master Servicer or such Servicer, as applicable, in its capacity as servicer under this Agreement and with respect to the transactions set forth or provided for herein and shall be subject to all the responsibilities, duties and liabilities relating thereto placed on the Master Servicer or such Servicer, as applicable, by the terms and provisions hereof; provided, that the Trustee, the Trust Administrator or the Master Servicer, as applicable, shall not be deemed to have made any representation or warranty as to any Mortgage Loan made by the Master Servicer or any Servicer, as applicable, and shall not effect any repurchases or substitutions of any Mortgage Loan; provided, further, that it is understood and acknowledged by the parties hereto that there will be a full period of transition (not to exceed ninety (90) days) before the actual servicing functions of any Servicer can be fully transferred to Wells Fargo as successor Servicer; provided, further, that during such period of transition Wells Fargo, as successor Servicer, shall continue to make all required Compensating Interest Payments and Advances.  As compensation therefor, the Trustee, the Trust Administrator or the Master Servicer, as applicable, shall be entitled to all funds relating to the Mortgage Loans that the Master Servicer or related Servicer (the “Replaced Servicer”) would have been entitled to charge to the related Collection Account if the Replaced Servicer had continued to act hereunder (except that the Replaced Servicer shall retain the right to be reimbursed for advances (including, without limitation, Advances and Servicing Advances) theretofore made by the Replaced Servicer with respect to which it would be entitled to be reimbursed as provided in Section 3.08 if it had not been so terminated or resigned).  

Notwithstanding the foregoing, if the Trustee, the Trust Administrator or the Master Servicer, as applicable, has become the successor to a Replaced Servicer, in accordance with this Section 8.02, the Trustee, the Trust Administrator or the Master Servicer, as applicable, may, if it shall be unwilling to so act, or shall, if it is unable to so act or has been directed to do so by DLJMC pursuant to Section 8.01, appoint, or petition a court of competent jurisdiction to appoint, any established mortgage loan servicing institution, the appointment of which does not adversely affect the then current rating of the Certificates, as the successor to the Master Servicer or a Servicer, as applicable, hereunder in the assumption of all or any part of the responsibilities, duties or liabilities of the Master Servicer or such Servicer, as applicable; provided, that such successor to the Master Servicer or the Servicer, as applicable, shall not be deemed to have made any representation or warranty as to any Mortgage Loan made by the Master Servicer or the related Servicer, as applicable.  Pending appointment of a successor to the Master Servicer or a Servicer, as applicable, hereunder, the Trustee, the Trust Administrator or the Master Servicer, as applicable, unless such party is prohibited by law from so acting, shall act in such capacity as provided herein.  In connection with such appointment and assumption, the Trustee, the Trust Administrator or the Master Servicer, as applicable, may make such arrangements for the compensation of such successor out of payments on Mortgage Loans as it and such successor shall agree; provided, however, that no such compensation shall be in excess of that permitted the Replaced Servicer, hereunder.  The Trustee, the Trust Administrator or the Master Servicer, as applicable, and such successor shall take such action, consistent with this Agreement, as shall be necessary to effectuate any such succession.  None of the Trustee, the Trust Administrator, the Master Servicer nor any other successor servicer shall be deemed to be in default hereunder by reason of any failure to make, or any delay in making, any distribution hereunder or any portion thereof caused by the failure of a Replaced Servicer to deliver, or any delay in delivering, cash, documents or records to it.

A Replaced Servicer that has been terminated shall, at the request of the Trustee, the Trust Administrator or the Master Servicer, as applicable, but at the expense of such Replaced Servicer deliver to the assuming party all documents and records relating to the applicable Mortgage Loans and an accounting of amounts collected and held by it and otherwise use commercially reasonable efforts to effect the orderly and efficient transfer and assignment of such servicing, but only to the extent of the Mortgage Loans serviced thereunder, to the assuming party.  Notwithstanding anything to the contrary contained herein, the termination of a Servicer under this Agreement shall not extend to any Sub-Servicer meeting the requirements of Section 3.02(a) and otherwise servicing the related Mortgage Loans in accordance with the servicing provisions of this Agreement.

The Master Servicer and each Servicer shall cooperate with the Trustee and the Trust Administrator and any successor servicer in effecting the termination of a Replaced Servicer’s responsibilities and rights hereunder, including without limitation, the transfer to such successor for administration by it of all cash amounts which shall at the time be credited by such Servicer to the applicable Collection Account or thereafter received with respect to the Mortgage Loans.

None of the Trustee, the Trust Administrator nor any other successor servicer shall be deemed to be in default hereunder by reason of any failure to make, or any delay in making, any distribution hereunder or any portion thereof caused by (a) the failure of the Master Servicer or any Servicer to (i) deliver, or any delay in delivering, cash, documents or records to it, or (ii) cooperate as required by this Agreement, or (b) restrictions imposed by any regulatory authority having jurisdiction over the Master Servicer or the related Servicer.

Any successor to a Servicer as servicer shall during the term of its service as servicer maintain in force the policy or policies that such Servicer is required to maintain pursuant to Section 3.09(b).

If a Servicer that has been terminated fails to pay all costs related to the transition of servicing to the successor Servicer, the successor Servicer shall be entitled to reimbursement of those amounts from the Trust.

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

SECTION 8.03.

Notification to Certificateholders.

(a)

Upon any termination or appointment of a successor to the Master Servicer or any Servicer, the Trust Administrator shall give prompt written notice thereof to the Seller and the Certificateholders at their respective addresses appearing in the Certificate Register and to the Rating Agencies, or, as applicable, the Master Servicer shall give prompt written notice thereof to the Trust Administrator.

(b)

Within two Business Days after the occurrence of any Event of Default, the Trust Administrator shall transmit by mail to the Seller and all Certificateholders, and the Rating Agencies notice of each such Event of Default hereunder known to the Trust Administrator, unless such Event of Default shall have been cured or waived.

SECTION 8.04.

Waiver of Events of Default.

The Holders representing at least 66-2/3% of the Voting Rights of Certificates affected by a default or Event of Default hereunder may waive any default or Event of Default; provided, however, that (a) a default or Event of Default under clause (g) of Section 8.01 may be waived, only by all of the Holders of Certificates affected by such default or Event of Default and (b) no waiver pursuant to this Section 8.04 shall affect the Holders of Certificates in the manner set forth in Section 12.01(b)(i), (ii) or (iii).  Upon any such waiver of a default or Event of Default by the Holders representing the requisite percentage of Voting Rights of Certificates affected by such default or Event of Default, such default or Event of Default shall cease to exist and shall be deemed to have been cured and remedied for every purpose hereunder.  No such waiver shall extend to any subsequent or other default or Event of Default or impair any right consequent thereon except to the extent expressly so waived.

ARTICLE IX

CONCERNING THE TRUSTEE

SECTION 9.01.

Duties of Trustee.

The Trustee, prior to the occurrence of an Event of Default and after the curing or waiver of all Events of Default that may have occurred, undertakes with respect to the Trust Fund to perform such duties and only such duties as are specifically set forth in this Agreement.  In case an Event of Default of which a  Responsible Officer of the Trustee shall have actual knowledge has occurred and remains uncured, the Trustee shall exercise such of the rights and powers vested in it by this Agreement, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs.  Any permissive right of the Trustee set forth in this Agreement shall not be construed as a duty.

The Trustee, upon receipt of all resolutions, certificates, statements, opinions, reports, documents, orders or other instruments furnished to the Trustee that are specifically required to be furnished pursuant to any provision of this Agreement shall examine them to determine whether they conform to the requirements of this Agreement.  The Trustee shall have no duty to recompute, recalculate or verify the accuracy of any resolution, certificate, statement, opinion, report, document, order or other instrument so furnished to the Trustee.  If any such instrument is found not to conform in any material respect to the requirements of this Agreement, the Trustee shall notify the Certificateholders of such instrument in the event that the Trustee, after so requesting, does not receive a satisfactorily corrected instrument.

No provision of this Agreement shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act or its own misconduct, its negligent failure to perform its obligations in compliance with this Agreement, or any liability which would be imposed by reason of its willful misfeasance or bad faith; provided, however, that:

(a)

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

(b)

the Trustee shall not be personally liable for an error of judgment made in good faith by a Responsible Officer or Responsible Officers of the Trustee, unless the Trustee was negligent in ascertaining or investigating the pertinent facts;

(c)

the Trustee shall not be personally liable with respect to any action taken, suffered or omitted to be taken by it in good faith in accordance with this Agreement at the direction of the Holders of Certificates evidencing greater than 50% of the Voting Rights allocated to each Class of Certificates relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Agreement;

(d)

no provision of this Agreement shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it; and

(e)

the Trustee shall have no responsibility for any act or omission of the Trust Administrator or a Custodian, it being understood and agreed that the Trustee, Trust Administrator and any Custodian are independent contractors and not agents, partners or joint venturers.

The Trustee shall not be deemed to have knowledge of any Event of Default or event which, with notice or lapse of time, or both, would become an Event of Default, unless a Responsible Officer of the Trustee shall have received written notice thereof from a Servicer, the Depositor or a Certificateholder, or a Responsible Officer of the Trustee has actual notice thereof, and in the absence of such notice no provision hereof requiring the taking of any action or the assumption of any duties or responsibility by the Trustee following the occurrence of any Event of Default or event which, with notice or lapse of time or both, would become an Event of Default, shall be effective as to the Trustee.

The Trustee shall have no duty hereunder with respect to any complaint, claim, demand, notice or other document it may receive or which may be alleged to have been delivered to or served upon it by the parties as a consequence of the assignment of any Mortgage Loan hereunder; provided, however, that the Trustee shall use its best efforts to remit to the Master Servicer or the related Servicer upon receipt of any such complaint, claim, demand, notice or other document (i) which is delivered to the Corporate Trust Office of the Trustee, (ii) of which a Responsible Officer has actual knowledge, and (iii) which contains information sufficient to permit the Trustee to make a determination that the real property to which such document relates is a Mortgaged Property.

SECTION 9.02.

Certain Matters Affecting the Trustee.

(a)

Except as otherwise provided in Section 9.01:

(i)

the Trustee may request and rely upon and shall be protected in acting or refraining from acting upon any resolution, Officer’s Certificate, certificate of auditors, Servicing Officers or any other certificate, statement, instrument, opinion, report, notice, request, consent, order, appraisal, bond or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties;

(iii)

the Trustee shall be under no obligation to exercise any of the trusts or powers vested in it by this Agreement or to institute, conduct or defend any litigation hereunder or in relation hereto at the request, order or direction of any of the Certificateholders pursuant to the provisions of this Agreement, unless such Certificateholders shall have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities which may be incurred therein or thereby; nothing contained herein shall, however, relieve the Trustee of the obligation, upon the occurrence of an Event of Default of which a Responsible Officer of the Trustee shall have actual knowledge (which has not been cured or waived), to exercise such of the rights and powers vested in it by this Agreement, and to use the same degree of care and skill in their exercise as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs;

If such corporation or association publishes reports of condition at least annually, pursuant to law or to the requirements of the aforesaid supervising or examining authority, then for the purposes of this Section 9.06 the combined capital and surplus of such corporation or association shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published.

If at any time the Trustee shall cease to be eligible in accordance with the provisions of Section 9.06 and shall fail to resign after written request thereto by the Depositor, or if at any time the Trustee shall become incapable of acting, or shall be adjudged a bankrupt or insolvent, or a receiver of the Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation or if the Trustee breaches any of its obligations or representations hereunder, then the Depositor may remove the Trustee and appoint a successor trustee by written instrument, in duplicate, one copy of which instrument shall be delivered to the Trustee and one copy to the successor trustee.  The Trustee may also be removed at any time by the Holders of Certificates evidencing not less than 50% of the Voting Rights evidenced by the Certificates.  Notice of any removal of the Trustee and acceptance of appointment by the successor trustee shall be given to the Rating Agencies by the Depositor.

If no successor trustee shall have been so appointed and have accepted appointment within 30 days after the giving of such notice of resignation or receipt of a notice of removal, the resigning Trustee may, at the Trust Fund’s expense, petition any court of competent jurisdiction for the appointment of a successor trustee.

Any successor trustee appointed as provided in Section 9.07 shall execute, acknowledge and deliver to the Depositor and to its predecessor trustee an instrument accepting such appointment hereunder and thereupon the resignation or removal of the predecessor trustee shall become effective and such successor trustee, without any further act, deed or conveyance, shall become fully vested with all the rights, powers, duties and obligations of its predecessor hereunder, with the like effect as if originally named as trustee herein.  The Depositor, upon receipt of all amounts due it hereunder, and the predecessor trustee shall execute and deliver such instruments and do such other things as may reasonably be required for more fully and certainly vesting and confirming in the successor trustee all such rights, powers, duties, and obligations.

No successor trustee shall accept appointment as provided in this Section 9.08 unless at the time of such acceptance such successor trustee shall be eligible under the provisions of Section 9.06 and its acceptance shall not adversely affect the then current rating of the Certificates.

Upon acceptance of appointment by a successor trustee as provided in this Section 9.08, the Depositor shall mail notice of the succession of such trustee hereunder to all Holders of Certificates at their addresses as shown in the Certificate Register.  If the Depositor fails to mail such notice within ten days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be mailed at the expense of the Depositor.

SECTION 9.09.

Merger or Consolidation of Trustee.

Any Person into which the Trustee may be merged or converted or with which it may be consolidated or any Person resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any Person succeeding to the business of the Trustee, shall be the successor of the Trustee hereunder, provided that such Person shall be eligible under the provisions of Section 9.06 without the execution or filing of any paper or further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding.

SECTION 9.10.

Appointment of Co-Trustee or Separate Trustee.

Notwithstanding any other provisions of this Agreement, at any time, for the purpose of meeting any legal requirements of any jurisdiction in which any part of the Trust Fund or property securing any Mortgage Note may at the time be located, the Master Servicer and the Trustee acting jointly shall have the power and shall execute and deliver all instruments to appoint one or more Persons approved by the Trustee to act as co-trustee or co-trustees jointly with the Trustee, or separate trustee or separate trustees, of all or any part of the Trust Fund, and to vest in such Person or Persons, in such capacity and for the benefit of the applicable Certificateholders, such title to the Trust Fund, or any part thereof, and, subject to the other provisions of this Section 9.10, such powers, duties, obligations, rights and trusts as the Master Servicer and the Trustee may consider necessary or desirable.  If the Master Servicer shall not have joined in such appointment within fifteen days after the receipt by it of a request to do so, or in the case an Event of Default shall have occurred and be continuing, the Trustee alone shall have the power to make such appointment.  No co-trustee or separate trustee hereunder shall be required to meet the terms of eligibility as a successor trustee under Section 9.06 and no notice to Certificateholders of the appointment of any co-trustee or separate trustee shall be required under Section 9.08.

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

(a)

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

(b)

no trustee hereunder shall be held personally liable by reason of any act or omission of any other trustee hereunder; and

(c)

the Master Servicer and the Trustee acting jointly may at any time accept the resignation of or remove any separate trustee or co-trustee.

Any notice, request or other writing given to the Trustee shall be deemed to have been given to each of the then separate trustees and co-trustees, as effectively as if given to each of them.  Every instrument appointing any separate trustee or co-trustee shall refer to this Agreement and the conditions of this Article IX.  Each separate trustee and co-trustee, upon its acceptance of the trusts conferred, shall be vested with the estates or property specified in its instrument of appointment, either jointly with the Trustee or separately, as may be provided therein, subject to all the provisions of this Agreement, specifically including every provision of this Agreement relating to the conduct of, affecting the liability of, or affording protection to, the Trustee.  Every such instrument shall be filed with the Trustee and a copy thereof given to the Master Servicer or the Servicers and the Depositor.

Any separate trustee or co-trustee may, at any time, constitute the Trustee its agent or attorney-in-fact, with full power and authority, to the extent not prohibited by law, to do any lawful act under or in respect of this Agreement on its behalf and in its name.  The Trust Administrator shall not be responsible for all action or inaction of any separate trustee or co-trustee. If any separate trustee or co-trustee shall die, become incapable of acting, resign or be removed, all of its estates, properties, rights, remedies and trusts shall vest in and be exercised by the Trustee, to the extent permitted by law, without the appointment of a new or successor trustee.

SECTION 9.11.

ARTICLE X

CONCERNING THE TRUST ADMINISTRATOR

SECTION 10.01.

Duties of Trust Administrator.

The Trust Administrator, prior to the occurrence of an Event of Default of which a Responsible Officer of the Trust Administrator shall have actual knowledge and after the curing or waiver of all Events of Default that may have occurred, undertakes with respect to the Trust Fund to perform such duties and only such duties as are specifically set forth in this Agreement.  In case an Event of Default of which a Responsible Officer of the Trust Administrator shall have actual knowledge has occurred and remains uncured, the Trust Administrator shall exercise such of the rights and powers vested in it by this Agreement, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs.  Any permissive right of the Trust Administrator set forth in this Agreement shall not be construed as a duty.

The Trust Administrator, upon receipt of all resolutions, certificates, statements, opinions, reports, documents, orders or other instruments furnished to the Trust Administrator that are specifically required to be furnished pursuant to any provision of this Agreement shall examine them to determine whether they conform to the requirements of this Agreement.  The Trust Administrator shall have no duty to recompute, recalculate or verify the accuracy of any resolution, certificate, statement, opinion, report, document, order or other instrument so furnished to the Trust Administrator.  If any such instrument is found not to conform in any material respect to the requirements of this Agreement, the Trust Administrator shall notify the Certificateholders of such instrument in the event that the Trust Administrator, after so requesting, does not receive a satisfactorily corrected instrument.

No provision of this Agreement shall be construed to relieve the Trust Administrator from liability for its own negligent action, its own negligent failure to act or its own misconduct, its negligent failure to perform its obligations in compliance with this Agreement, or any liability which would be imposed by reason of its willful misfeasance or bad faith; provided, however, that:

(a)

prior to the occurrence of an Event of Default of which a Responsible Officer of the Trust Administrator shall have actual knowledge, and after the curing or of all such Events of Default that may have occurred, the duties and obligations of the Trust Administrator shall be determined solely by the express provisions of this Agreement, the Trust Administrator shall not be personally liable except for the performance of such duties and obligations as are specifically set forth in this Agreement, no implied covenants or obligations shall be read into this Agreement against the Trust Administrator and the Trust Administrator may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trust Administrator and conforming to the requirements of this Agreement which it reasonably believed in good faith to be genuine and to have been duly executed by the proper authorities respecting any matters arising hereunder;

(b)

the Trust Administrator shall not be personally liable for an error of judgment made in good faith by a Responsible Officer or Responsible Officers of the Trust Administrator, unless the Trust Administrator was negligent in ascertaining or investigating the pertinent facts;

(c)

the Trust Administrator shall not be personally liable with respect to any action taken, suffered or omitted to be taken by it in good faith in accordance with this Agreement or at the direction of the Holders of Certificates evidencing greater than 50% of the Voting Rights allocated to each Class of Certificates relating to the time, method and place of conducting any proceeding for any remedy available to the Trust Administrator, or exercising any trust or power conferred upon the Trust Administrator, under this Agreement; and

(d)

no provision of this Agreement shall require the Trust Administrator to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it.

The Trust Administrator shall have no duty (A) to see to any recording, filing or depositing of this Agreement or any agreement referred to herein or any financing statement or continuation statement evidencing a security interest, or to see to the maintenance of any such recording, filing or depositing or to any rerecording, refiling or redepositing of any thereof, (B) to see to any insurance, or (C) to see to the payment or discharge of any tax, assessment or other governmental charge or any lien or encumbrance of any kind owing with respect to, assessed or levied against, any part of the Trust Fund other than from funds available in the Certificate Account.

Except with respect to an Event of Default described in clause (a) of Section 8.01, the Trust Administrator shall not be deemed to have knowledge of any Event of Default or event which, with notice or lapse of time, or both, would become an Event of Default, unless a Responsible Officer of the Trust Administrator shall have received written notice thereof from the Master Servicer or a Servicer, the Depositor, or a Certificateholder, or a Responsible Officer of the Trust Administrator has actual notice thereof, and in the absence of such notice no provision hereof requiring the taking of any action or the assumption of any duties or responsibility by the Trust Administrator following the occurrence of any Event of Default or event which, with notice or lapse of time or both, would become an Event of Default, shall be effective as to the Trust Administrator.

The Trust Administrator shall have no duty hereunder with respect to any complaint, claim, demand, notice or other document it may receive or which may be alleged to have been delivered to or served upon it by the parties as a consequence of the assignment of any Mortgage Loan hereunder; provided, however, that the Trust Administrator shall use its best efforts to remit to the Master Servicer or the Servicer upon receipt of any such complaint, claim, demand, notice or other document (i) which is delivered to the Corporate Trust Office of the Trust Administrator, (ii) of which a Responsible Officer has actual knowledge, and (iii) which contains information sufficient to permit the Trust Administrator to make a determination that the real property to which such document relates is a Mortgaged Property.

the Trust Administrator shall not be required to expend its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such liability is not assured to it;

SECTION 10.03.

Trust Administrator Not Liable for Certificates or Mortgage Loans.

The recitals contained herein shall be taken as the statements of the Depositor or the Master Servicer or a Servicer, as the case may be, and the Trust Administrator assumes no responsibility for their correctness.

The Depositor, upon receipt of all amounts due it hereunder, and the predecessor trust administrator shall execute and deliver such instruments and do such other things as may reasonably be required for more fully and certainly vesting and confirming in the successor trust administrator all such rights, powers, duties, and obligations.

No successor trust administrator shall accept appointment as provided in this Section 10.08 unless at the time of such acceptance such successor trust administrator shall be eligible under the provisions of Section 10.06 and its acceptance shall not adversely affect the then current rating of the Certificates.

Upon acceptance of appointment by a successor trust administrator as provided in this Section 10.08, the Depositor shall mail notice of the succession of such trust administrator hereunder to all Holders of Certificates at their addresses as shown in the Certificate Register.  If the Depositor fails to mail such notice within ten days after acceptance of appointment by the successor trust administrator, the successor trust administrator shall cause such notice to be mailed at the expense of the Depositor.

SECTION 10.09.

Merger or Consolidation of Trust Administrator.

Any Person into which the Trust Administrator may be merged or converted or with which it may be consolidated or any Person resulting from any merger, conversion or consolidation to which the Trust Administrator shall be a party, or any Person succeeding to the business of the Trust Administrator, shall be the successor of the Trust Administrator hereunder, provided that such Person shall be eligible under the provisions of Section 10.06 without the execution or filing of any paper or further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding.

SECTION 10.10.

Appointment of Co-Trust Administrator or Separate Trust Administrator.

Notwithstanding any other provisions of this Agreement, at any time, for the purpose of meeting any legal requirements of any jurisdiction in which any part of the Trust Fund or property securing any Mortgage Note may at the time be located, the Master Servicer and the Trust Administrator acting jointly shall have the power and shall execute and deliver all instruments to appoint one or more Persons approved by the Trust Administrator to act as co-trust administrator or co-trust administrators jointly with the Trust Administrator, or separate trust administrator or separate trust administrators, of all or any part of the Trust Fund, and to vest in such Person or Persons, in such capacity and for the benefit of the applicable Certificateholders, such title to the Trust Fund, or any part thereof, and, subject to the other provisions of this Section 10.10, such powers, duties, obligations, rights and trusts as the Master Servicer and the Trust Administrator may consider necessary or desirable.  If the Master Servicer shall not have joined in such appointment within fifteen days after the receipt by it of a request to do so, or in the case an Event of Default shall have occurred and be continuing, the Trust Administrator alone shall have the power to make such appointment.  No co-trust administrator or separate trust administrator hereunder shall be required to meet the terms of eligibility as a successor trust administrator under Section 10.06 and no notice to Certificateholders of the appointment of any co-trust administrator or separate trust administrator shall be required under Section 10.08.

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

(a)

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

(b)

no trust administrator hereunder shall be held personally liable by reason of any act or omission of any other trust administrator hereunder; and

(c)

the Master Servicer and the Trust Administrator acting jointly may at any time accept the resignation of or remove any separate trust administrator or co-trust administrator.

Any notice, request or other writing given to the Trust Administrator shall be deemed to have been given to each of the then separate trust administrators and co-trust administrators, as effectively as if given to each of them.  Every instrument appointing any separate trust administrator or co-trust administrator shall refer to this Agreement and the conditions of this Article X.  Each separate trust administrator and co-trust administrator, upon its acceptance of the trusts conferred, shall be vested with the estates or property specified in its instrument of appointment, either jointly with the Trust Administrator or separately, as may be provided therein, subject to all the provisions of this Agreement, specifically including every provision of this Agreement relating to the conduct of, affecting the liability of, or affording protection to, the Trust Administrator.  Every such instrument shall be filed with the Trust Administrator and a copy thereof given to the Master Servicer or the Servicers and the Depositor.

Any separate trust administrator or co-trust administrator may, at any time, constitute the Trust Administrator, its agent or attorney-in-fact, with full power and authority, to the extent not prohibited by law, to do any lawful act under or in respect of this Agreement on its behalf and in its name.  The Trust Administrator shall not be responsible for any action or inaction of any separate Trust Administrator or Co-Trust Administrator.  If any separate trust administrator or co-trust administrator shall die, become incapable of acting, resign or be removed, all of its estates, properties, rights, remedies and trusts shall vest in and be exercised by the Trust Administrator, to the extent permitted by law, without the appointment of a new or successor trust administrator.

The Master Servicer and each Servicer, upon request, shall furnish the Trust Administrator with all such information related to the Mortgage Loans in the possession of the Master Servicer or such Servicer as may be reasonably required in connection with the preparation by the Trust Administrator of all tax and information returns of the Trust Fund, and the Trust Administrator shall sign such returns. The Master Servicer and each Servicer, severally and not jointly, shall indemnify the Trust Administrator for all reasonable costs, including legal fees and expenses, related to errors in such tax returns due to errors only in such information provided by the Master Servicer or by such Servicer.

SECTION 10.13.

Determination of Certificate Index.

On each Interest Determination Date, the Trust Administrator shall determine each Certificate Index for the Accrual Period and inform the Master Servicer of such rate and such rate shall be final and binding, absent a manifest error of the Trust Administrator.

SECTION 12.04.

Intention of Parties.

(a)

It is the express intent of the Depositor, the Seller, the Master Servicer, the Special Servicer, the Modification Oversight Agent, the Servicers, the Trust Administrator and the Trustee that (i) the conveyance by DLJMC of the Mortgage Loans to the Depositor pursuant to the Assignment and Assumption Agreement and (v) the conveyance by the Depositor to the Trustee as provided for in Section 2.01 of each of the Seller’s and Depositor’s right, title and interest in and to the Mortgage Loans be, and be construed as, an absolute sale and assignment by DLJMC to the Depositor and by the Depositor to the Trustee of the Mortgage Loans for the benefit of the Certificateholders.  Further, it is not intended that any conveyance be deemed to be a pledge of the Mortgage Loans by DLJMC to the Depositor or by the Depositor to the Trustee to secure a debt or other obligation.  However, in the event that the Mortgage Loans are held to be property of DLJMC or the Depositor, as applicable, or if for any reason the Assignment and Assumption Agreement or this Agreement is held or deemed to create a security interest in the Mortgage Loans, then it is intended that (i) this Agreement shall also be deemed to be a security agreement within the meaning of Articles 8 and 9 of the New York Uniform Commercial Code and the Uniform Commercial Code of any other applicable jurisdiction; (ii) the conveyances provided for in Section 2.01 shall be deemed to be a grant by the Seller and the Depositor to the Trustee on behalf of the Certificateholders, to secure payment in full of the Secured Obligations (as defined below), of a security interest in all of the Seller’s and the Depositor’s right (including the power to convey title thereto), title and interest, whether now owned or hereafter acquired, in and to the Mortgage Loans, including the Mortgage Notes, the Mortgages, any related insurance policies and all other documents in the related Mortgage Files, and all accounts, contract rights, general intangibles, chattel paper, instruments, documents, money, deposit accounts, certificates of deposit, goods, letters of credit, advices of credit and uncertificated securities consisting of, arising from or relating to (A) the Mortgage Loans, including with respect to each Mortgage Loan, the Mortgage Note and related Mortgage, and all other documents in the related Trustee Mortgage Files, and including any Qualified Substitute Mortgage Loans; (B) pool insurance policies, hazard insurance policies and any bankruptcy bond relating to the foregoing, if applicable; (C) the Certificate Account; (D) the Collection Account; (E) all amounts payable after the Cut-off Date to the holders of the Mortgage Loans in accordance with the terms thereof; (F) all income, payments, proceeds and products of the conversion, voluntary or involuntary, of the foregoing into cash, instruments, securities or other property, including without limitation all amounts from time to time held or invested in the Certificate Account, whether in the form of cash, instruments, securities or other property; and (G) all cash and non-cash proceeds of any of the foregoing; (iii) the possession by the Trustee or any other agent of the Trustee of Mortgage Notes or such other items of property as constitute instruments, money, documents, advices of credit, letters of credit, goods, certificated securities or chattel paper shall be deemed to be a “possession by the secured party,” or possession by a purchaser or a person designated by him or her, for purposes of perfecting the security interest pursuant to the Uniform Commercial Code (including, without limitation, Sections 9-313, 8-313 or 8-321 thereof); and (iv) notifications to persons holding such property, and acknowledgments, receipts or confirmations from persons holding such property, shall be deemed notifications to, or acknowledgments, receipts or confirmations from, financial intermediaries, securities intermediaries, bailees or agents (as applicable) of the Trustee for the purpose of perfecting such security interest under applicable law.  “Secured Obligations” means (i) the rights of each Certificateholder to be paid any amount owed to it under this Agreement and (ii) all other obligations of the Seller and the Depositor under this Agreement and the Assignment and Assumption Agreement.

(b)

The Seller and the Depositor, and, at the Depositor’s direction, the Master Servicer or the Servicers, the Trustee and the Trust Administrator, shall, to the extent consistent with this Agreement, take such reasonable actions as may be necessary to ensure that, if this Agreement were deemed to create a security interest in the Mortgage Loans and the other property described above, such security interest would be deemed to be a perfected security interest of first priority as applicable.  The Depositor shall prepare and file, at the related Servicer’s expense, all filings necessary to maintain the effectiveness of any original filings necessary under the Uniform Commercial Code as in effect in any jurisdiction to perfect the Trustee’s security interest in or lien on the Mortgage Loans, including without limitation (i) continuation statements, and (ii) such other statements as may be occasioned by any transfer of any interest of the Master Servicer or any Servicer or the Depositor in any Mortgage Loan.

SECTION 12.05.

SECTION 12.07.

Limitation on Rights of Certificateholders.

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

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

No Certificateholder shall have any right by virtue or by availing itself of any provisions of this Agreement to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Agreement, unless such Holder previously shall have given to the Trust Administrator a written notice of an Event of Default and of the continuance thereof, as provided herein, and unless the Holders of Certificates evidencing not less than 25% of the Voting Rights evidenced by the Certificates shall also have made written request upon the Trust Administrator to institute such action, suit or proceeding in its own name as Trust Administrator hereunder and shall have offered to the Trust Administrator such reasonable indemnity as it may require against the costs, expenses, and liabilities to be incurred therein or thereby, and the Trust Administrator, for 60 days after its receipt of such notice, request and offer of indemnity, shall have neglected or refused to institute any such action, suit or proceeding; it being understood and intended, and being expressly covenanted by each Certificateholder with every other Certificateholder and the Trust Administrator, that no one or more Holders of Certificates shall have any right in any manner whatever by virtue or by availing itself or themselves of any provisions of this Agreement to affect, disturb or prejudice the rights of the Holders of any other of the Certificates, or to obtain or seek to obtain priority over or preference to any other such Holder or to enforce any right under this Agreement, except in the manner herein provided and for the common benefit of all Certificateholders.  For the protection and enforcement of the provisions of this Section 12.07, each and every Certificateholder and the Trust Administrator shall be entitled to such relief as can be given either at law or in equity.

SECTION 12.08.

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

SECTION 12.09.

Notwithstanding the foregoing, it is understood and agreed that neither (i) promotions undertaken by the Master Servicer, any Servicer (other than SPS and WMMSC), the Trust Administrator or the Trustee or any affiliate of any such party that originates mortgage loans in the normal course, which are directed to the general public at large, or segments thereof, including, without limitation, mass mailings based on commercially acquired mailing lists or newspaper, radio and television advertisements nor (ii) serving the refinancing needs of a Mortgagor who, without solicitation, contacts either party in connection with the refinance of such Mortgage or Mortgage Loan, shall constitute solicitation under this Section 12.10, provided, that no segment of the general public shall consist primarily of the borrowers or obligors under the Mortgage Loans.  

None of the Depositor, the Seller, the Master Servicer, any Servicer, the Trust Administrator or the Trustee shall permit the sale of the name of any Mortgagor or any list of names that consist primarily of the Mortgages to any Person.

WMMSC covenants and agrees that it shall not take any action to solicit the refinancing of any Mortgage Loan following the date of the Series Supplement or provide information to any other entity to solicit the refinancing of any Mortgage Loan; provided, that the foregoing shall not preclude WMMSC or any of its affiliates from (a) engaging in general solicitations to its customer base, including by mass mailing or as part of monthly or periodic statements mailed to its borrowers or to holders of deposit or other accounts, (b) engaging in solicitations to the general public, including without limitation by mass mailing, newspaper, radio, television or other media which are not specifically directed toward the Mortgagors, (c) engaging in solicitations of optional insurance or other bank products (not including mortgage loans), (d) refinancing the Mortgage Loan of any Mortgagor who, without solicitation, contacts WMMSC to request the refinancing of the related Mortgage Loan or (e) engaging in any action to solicit the refinancing of any Mortgage Loan to the extent such action would be permitted under the Fannie Mae Selling Guide or the Fannie Mae Servicing Guide, provided that WMMSC agrees that it shall not, in engaging in any such solicitation, specifically target any of the Mortgage Loans.

ARTICLE XIII

EXCHANGE ACT REPORTING

SECTION 13.01.

Commission Reporting.

The Trust Administrator, each Servicer and the Master Servicer shall reasonably cooperate with the Depositor in connection with the Trust’s satisfying the reporting requirements under the Exchange Act.

[For Privately Offered Certs only] [No transfer of this Certificate shall be made unless such transfer is made pursuant to an effective registration statement under the Securities Act and any applicable state securities laws or is exempt from the registration requirements under said Act and such laws.  In the event that a transfer is to be made in reliance upon an exemption from the Securities Act and such laws, in order to assure compliance with the Securities Act and such laws, the Certificateholder desiring to effect such transfer and such Certificateholder’s prospective transferee shall each certify to the Trust Administrator in writing the facts surrounding the transfer and (i) deliver a letter in substantially the form of either Exhibit L and either (A) Exhibit M 1, provided that all of the Certificates of the Class shall be transferred to one investor or the Depositor otherwise consents to such transfer, or (B) Exhibit M-2 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 Securities Act.

This Certificate does not evidence an obligation of, or an interest in, and is not guaranteed by the Depositor, the Seller, the Master Servicer, the Servicers, the Special Servicer, the Modification Oversight Agent, the Trustee or the Trust Administrator referred to below or any of their respective affiliates.  Neither this Certificate nor the Mortgage Loans are guaranteed or insured by any governmental agency or instrumentality.

This certifies that _____________________________, is the registered owner of the Percentage Interest evidenced by this Certificate (obtained by dividing the denomination of this Certificate by the aggregate of the denominations of all Certificates of the Class to which this Certificate belongs) in certain monthly distributions with respect to a Trust Fund consisting primarily of the Mortgage Loans deposited by Credit Suisse First Boston Mortgage Securities Corp. (the “Depositor”).  The Trust Fund was created pursuant to a Series Supplement dated as of the Cut-off Date specified above and the Standard Terms of Pooling and Servicing Agreement dated September 1, 2007 (collectively, the “Agreement”) by and among the Depositor, the Seller(s), the Master Servicer, the Trust Administrator, the Special Servicer, the Modification Oversight Agent, the Trustee and the Servicers that are party to the Series Supplement. To the extent not defined herein, the capitalized terms used herein have the meanings assigned in the Agreement.  This Certificate is issued under and is subject to the terms, provisions and conditions of the Agreement, to which Agreement the Holder of this Certificate by virtue of the acceptance hereof assents and by which such Holder is bound.

No transfer of this Certificate shall be made unless such transfer is made pursuant to an effective registration statement under the Securities Act and any applicable state securities laws or is exempt from the registration requirements under said Act and such laws.  In the event that a transfer is to be made in reliance upon an exemption from the Securities Act and such laws, in order to assure compliance with the Securities Act and such laws, the Certificateholder desiring to effect such transfer and such Certificateholder’s prospective transferee shall each certify to the Trust Administrator in writing the facts surrounding the transfer and (i) deliver a letter in substantially the form of either Exhibit L and either (A) Exhibit M-1, provided that all of the Certificates of the Class shall be transferred to one investor or the Depositor otherwise consents to such transfer, or (B) Exhibit M-2 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 Securities Act.  The Holder hereof desiring to effect such transfer shall, and does hereby agree to, indemnify the Trustee, the Trust Administrator and the Depositor against any liability that may result if the transfer is not so exempt or is not made in accordance with such federal and state laws.

Pursuant to the Agreement, no transfer of an ERISA-Restricted Certificate shall be made unless the Trust Administrator shall have received either (i) a representation letter from the transferee of such ERISA-Restricted 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 arrangement subject to Section 406 of ERISA or Section 4975 of the Code, or a person using the assets of any such plan or arrangement which representation letter shall not be an expense of the Trustee, the Trust Administrator or the Trust Fund, (ii) if the purchaser is an insurance company and the ERISA-Restricted 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 Certificate are covered under Sections I and III of PTCE 95-60 or (iii) in the case of any such ERISA-Restricted Certificate presented for registration in the name of an employee benefit plan subject to Section 406 of 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 Trust Administrator 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 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 representation shall be deemed to have been made to the Trust Administrator by the transferee’s acceptance of an ERISA-Restricted Certificate or by any beneficial owner who purchases an interest in this 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 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 this certificate shall be void and of no effect.

Reference is hereby made to the further provisions of this Certificate set forth following the signature page hereof, which further provisions shall for all purposes have the same effect as if set forth at this place.

This Certificate shall not be entitled to any benefit under the Agreement or be valid for any purpose unless manually countersigned by an authorized signatory of the Trust Administrator.

On any Distribution Date on which the Stated Principal Balance of Mortgage Loans in such Loan Groups as are specified in the Agreement are less than those percentages set forth in the Agreement, all remaining Mortgage Loans in such Loan Groups and all property acquired in respect of such Mortgage Loans may be purchased as provided in the Agreement.  In the event that no such purchase occurs, the obligations and responsibilities created by the Agreement will terminate upon the later of the maturity or other liquidation (or any advance with respect thereto) of the last Mortgage Loan remaining in the Trust Fund or the disposition of all property in respect thereof and the distribution to Certificateholders of all amounts required to be distributed pursuant to the Agreement.  In no event, however, will the trust created by the Agreement continue beyond the earlier of (i) the expiration of 21 years from the death of the last survivor of the descendants living at the date of the Agreement of a certain person named in the Agreement or (ii) 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 related Cut-off Date.  Any term used herein that is defined in the Agreement shall have the meaning assigned in the Agreement, and nothing herein shall be deemed inconsistent with that meaning.

IN WITNESS WHEREOF, the Trust Administrator has caused this Certificate to be duly executed.

CREDIT SUISSE FIRST BOSTON MORTGAGE SECURITIES CORP.

[Name of Series Trust],

Mortgage-Backed Pass-Through Certificates, [Series Name]

Class [__]-[__]-[__]

This Certificate is one of a duly authorized issue of Certificates designated as Credit Suisse First Boston Mortgage Securities Corp., Mortgage-Backed Pass-Through Certificates, [Series Name], of the Series specified on the face hereof (herein collectively called the “Certificates”), and representing a beneficial ownership interest in the Trust Fund created by the Agreement.

The Certificateholder, by its acceptance of this Certificate, agrees that it will look solely to the funds on deposit in the Certificate Account for payment hereunder and that neither the Trustee nor the Trust Administrator is liable to the Certificateholders for any amount payable under this Certificate or the Agreement or, except as expressly provided in the Agreement, subject to any liability under the Agreement.

This Certificate does not purport to summarize the Agreement and reference is made to the Agreement for the interests, rights and limitations of rights, benefits, obligations and duties evidenced thereby, and the rights, duties and immunities of the Trustee and the Trust Administrator.

Pursuant to the terms of the Agreement, a distribution will be made on the 25th day of each month, or, if such 25th day is not a Business Day, the Business Day immediately following (the “Distribution Date”), commencing on the first Distribution Date specified on the face hereof, to the Person in whose name this Certificate is registered at the close of business on the applicable Record Date in an amount equal to the product of the Percentage Interest evidenced by this Certificate and the amount required to be distributed to Holders of Certificates of the Class to which this Certificate belongs on such Distribution Date pursuant to the Agreement.  The Record Date applicable to each Distribution Date is (1) with respect to all Certificates other than the LIBOR Certificates that are Book-Entry Certificates on such Distribution Date, the close of business on the last day of the calendar month preceding the month in which such Distribution Date occurs and (2) with respect to the LIBOR Certificates that are Book-Entry Certificates on such Distribution Date, the close of business on the Business Day immediately preceding such Distribution Date.

Distributions on this Certificate shall be made by wire transfer of immediately available funds to the account of the Holder hereof at a bank or other entity having appropriate facilities therefor, if such Certificateholder shall have so notified the Trust Administrator in writing at least five Business Days prior to the related Record Date and such Certificateholder shall satisfy the conditions to receive such form of payment set forth in the Agreement, or, if not, by check mailed by first class mail to the address of such Certificateholder appearing in the Certificate Register.  The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the Corporate Trust Office or such other location specified in the notice to Certificateholders of such final distribution.

The Agreement permits, with certain exceptions therein provided, the amendment thereof and the modification of the rights and obligations of the Trustee, the Trust Administrator and the rights of the Certificateholders under the Agreement at any time by the Depositor, the Master Servicer, the Servicers, the Special Servicer, the Modification Oversight Agent, the Seller, the Trustee and the Trust Administrator with the consent of the Holders of Certificates affected by such amendment evidencing the requisite Percentage Interest, as provided in the Agreement.  Any such consent by the Holder of this Certificate shall be conclusive and binding on such Holder and upon all future Holders of this Certificate and of any Certificate issued upon the transfer hereof or in exchange therefor or in lieu hereof whether or not notation of such consent is made upon this Certificate.  The Agreement also permits the amendment thereof, in certain limited circumstances, without the consent of the Holders of any of the Certificates.

As provided in the Agreement and subject to certain limitations therein set forth, the transfer of this Certificate is registrable in the Certificate Register of the Trust Administrator upon surrender of this Certificate for registration of transfer at the Corporate Trust Office or the office or agency maintained by the Trust Administrator in New York, New York, accompanied by a written instrument of transfer in form satisfactory to the Trust Administrator and the Certificate Registrar duly executed by the holder hereof or such holder’s attorney duly authorized in writing, and thereupon one or more new Certificates of the same Class in authorized denominations and evidencing the same aggregate Percentage Interest in the Trust Fund will be issued to the designated transferee or transferees.

The Certificates are issuable only as registered Certificates without coupons in denominations specified in the Agreement.  As provided in the Agreement and subject to certain limitations therein set forth, Certificates are exchangeable for new Certificates of the same Class in authorized denominations and evidencing the same aggregate Percentage Interest, as requested by the Holder surrendering the same.

No service charge will be made for any such registration of transfer or exchange, but the Trust Administrator may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

The Depositor, each Servicer, the Master Servicer, the Seller, the Trustee and the Trust Administrator and any agent of the Depositor, each Servicer, the Master Servicer, the Seller, the Trustee or the Trust Administrator may treat the Person in whose name this Certificate is registered as the owner hereof for all purposes, and none of the Depositor, the Servicers, the Master Servicer, the Seller, the Trustee, the Trust Administrator or any such agent shall be affected by any notice to the contrary.

On any Distribution Date on which the Stated Principal Balance of Mortgage Loans in such Loan Groups as are specified in the Agreement are less than those percentages set forth in the Agreement, all remaining Mortgage Loans in such Loan Groups and all property acquired in respect of such Mortgage Loans may be purchased as provided in the Agreement.  In the event that no such purchase occurs, the obligations and responsibilities created by the Agreement will terminate upon the later of the maturity or other liquidation (or any advance with respect thereto) of the last Mortgage Loan remaining in the Trust Fund or the disposition of all property in respect thereof and the distribution to Certificateholders of all amounts required to be distributed pursuant to the Agreement.  In no event, however, will the trust created by the Agreement continue beyond the earlier of (i) the expiration of 21 years from the death of the last survivor of the descendants living at the date of the Agreement of a certain person named in the Agreement or (ii) 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 related Cut-off Date.

[NAME OF OFFICER], being first duly sworn, deposes and says:

1.

That he is [Title of Officer] or [Name of Owner] (record or beneficial owner (the “Owner”) of the Class [AR/AR-L] Certificates (the “Class [AR/AR-L] Certificates”)), a [savings institution] [corporation] duly organized and existing under the laws of [the State of             ] [the United States], on behalf of which he makes this affidavit and agreement.

2.

That the Owner (i) is not and will not be a “disqualified organization” as of [date of transfer] within the meaning of Section 860E(e)(5) of the Internal Revenue Code of 1986, as amended (the “Code”), (ii) will endeavor to remain other than a disqualified organization for so long as it retains its ownership interest in the Class [AR/AR-L] Certificates, and (iii) is acquiring the Class [AR/AR-L] Certificates for its own account.  A “Permitted Transferee” is any person other than a “disqualified organization.”  (For this purpose, a “disqualified organization” means the United States, any state or political subdivision thereof, any agency or instrumentality of any of the foregoing (other than an instrumentality all of the activities of which are subject to tax and, except for the Federal Home Loan Mortgage Corporation, a majority of whose board of directors is not selected by any such governmental entity) or any foreign government, international organization or any agency or instrumentality of such foreign government or organization, any rural electric or telephone cooperative, or any organization (other than certain farmers’ cooperatives) that is generally exempt from federal income tax unless such organization is subject to the tax on unrelated business taxable income).

3.

That the Owner is aware (i) of the tax that would be imposed on transfers of Class [AR/AR-L] Certificates to disqualified organizations under the Code; (ii) that such tax would be on the transferor, or, if such transfer is through an agent (which person includes a broker, nominee or middleman) for a non-Permitted Transferee, on the agent; (iii) that the person otherwise liable for the tax shall be relieved of liability for the tax if the transferee furnishes to such person an affidavit that the transferee is a Permitted Transferee and, at the time of transfer, such person does not have actual knowledge that the affidavit is false; and (iv) that the Class [AR/AR-L] Certificates may be “noneconomic residual interests” within the meaning of Treasury regulations promulgated pursuant to the Code and that the transferor of a noneconomic residual interest will remain liable for any taxes due with respect to the income on such residual interest, if a significant purpose of the transfer was to enable the transferor to impede the assessment or collection of tax.

4.

That the Owner is aware of the tax imposed on a “pass-through entity” holding Class [AR/AR-L] Certificates if at any time during the taxable year of the pass-through entity a non-Permitted Transferee is the record holder of an interest in such entity.

[_________________________] Mortgage Backed Pass Through Certificates, Series 200_ ___, Class AR (the “Certificates”)

Ladies and Gentlemen:

This letter is delivered to you in connection with the sale by _________________ (the “Seller”) to ____________________________________ (the “Purchaser”) of a _______% Percentage Interest in the above referenced Certificates, pursuant to Section 6.02 of the Series Supplement dated as of ___________________ and the Standard Terms of Pooling and Servicing Agreement dated September 1, 2007 (collectively, the “Agreement”) by and among the Depositor, the Seller(s), the Master Servicer, the Trust Administrator, the Special Servicer, the Modification Oversight Agent, the Trustee and the Servicers that are party to the Series Supplement.  All terms used herein and not otherwise defined shall have the meanings set forth in the Agreement.  The Seller hereby certifies, represents and warrants to, and covenants with, the Depositor, the Trust Administrator and the Trustee that:

1.

No purpose of the Seller relating to sale of the Certificate by the Seller to the Purchaser is or will be to enable the Seller to impede the assessment or collection of any tax.

2.

The Seller understands that the Purchaser has delivered to the Trust Administrator a transfer affidavit and agreement in the form attached to the Agreement as Exhibit N.  The Seller does not know or believe that any representation contained therein is false.

3.

The Seller has no actual knowledge that the proposed Transferee is not a Permitted Transferee.

4.

The Seller has no actual knowledge that the Purchaser would be unwilling or unable to pay taxes due on its share of the taxable income attributable to the Certificate.

5.

The Seller has conducted a reasonable investigation of the financial condition of the Purchaser and, as a result of the investigation, found that the Purchaser has historically paid its debts as they came due, and found no significant evidence to indicate that the Purchaser will not continue to pay its debts as they come due in the future.

6.

The Purchaser has represented to the Seller that, if the Certificate constitutes a noneconomic residual interest, it (i) understands that as holder of a noneconomic residual interest it may incur tax liabilities in excess of any cash flows generated by the interest, and (ii) intends to pay taxes associated with its holding of the Certificate as they become due.

Very truly yours,

[SELLER]

The information set forth in Schedule I, with respect to the Mortgage Loans, is complete, true and correct in all material respects;

No Mortgage Loan is 30 days or more contractually Delinquent in payment and there are no material defaults under the terms of any Mortgage Loan;

(iii)

All taxes, governmental assessments, insurance premiums, water, sewer and municipal charges, leasehold payments or ground rents which previously became due and owing have been paid, or escrow funds have been established in an amount sufficient to pay for every such escrowed item which remains unpaid and which has been assessed but is not yet due and payable;

(iv)

The terms of the Mortgage Note and the Mortgage have not been impaired, waived, altered or modified in any respect, except by written instruments which have been recorded or sent for recording to the extent any such recordation is required by law, or, necessary to protect the interest of the Depositor. No other instrument of waiver, alteration or modification has been executed, and no Mortgagor has been released, in whole or in part, from the terms thereof except in connection with an assumption agreement and which assumption agreement is part of the Mortgage File and the terms of which are reflected in Schedule I; the substance of any such waiver, alteration or modification has been approved by the issuer of any related Mortgage Guaranty Insurance Policy and title insurance policy, to the extent required by the related policies;

(v)

The Mortgage Note and the Mortgage are not subject to any right of rescission, set-off, counterclaim or defense, including, without limitation, the defense of usury, nor will the operation of any of the terms of the Mortgage Note or the Mortgage, or the exercise of any right thereunder, render the Mortgage Note or Mortgage unenforceable, in whole or in part, or subject to any right of rescission, set-off, counterclaim or defense, including the defense of usury, and no such right of rescission, set-off, counterclaim or defense has been asserted with respect thereto;

(vi)

All buildings or other customarily insured improvements upon the Mortgaged Property are insured by an insurer acceptable under the FNMA Guides, against loss by fire, hazards of extended coverage and such other hazards as are provided for in the FNMA Guides or by FHLMC, as well as all additional requirements set forth in Section 4.09 of this Agreement. All such standard hazard policies are in full force and effect and on the date of origination contained a standard mortgagee clause naming DLJMC and its successors in interest and assigns as loss payee and such clause is still in effect and all premiums due thereon have been paid.  If required by the Flood Disaster Protection Act of 1973, as amended, the Mortgage Loan is covered by a flood insurance policy meeting the requirements of the current guidelines of the Federal Insurance Administration which policy conforms to FNMA and FHLMC requirements, as well as all additional requirements set forth in Section 4.09 of this Agreement.  Such policy was issued by an insurer acceptable under FNMA or FHLMC guidelines.  The Mortgage obligates the Mortgagor thereunder to maintain all such insurance at the Mortgagor’s cost and expense, and on the Mortgagor’s failure to do so, authorizes the holder of the Mortgage to maintain such insurance at the Mortgagor’s cost and expense and to seek reimbursement therefor from the Mortgagor;

(vii)

Each Mortgage Loan at the time it was made complied in all material respects with all applicable local, state and federal laws, including, without limitation, usury, equal credit opportunity, disclosure, recording and all applicable predatory and abusive lending laws;

The related Mortgage is a valid, subsisting, enforceable and perfected first lien on the Mortgaged Property, including for Mortgage Loans that are not Cooperative Loans, all buildings on the Mortgaged Property and all installations and mechanical, electrical, plumbing, heating and air conditioning systems affixed to such buildings, and all additions, alterations and replacements made at any time with respect to the foregoing securing the Mortgage Note’s original principal balance.  The Mortgage and the Mortgage Note do not contain any evidence of any security interest or other interest or right thereto.  Such lien is free and clear of all adverse claims, liens and encumbrances having priority over the first lien, as applicable, of the Mortgage subject only to (1) the lien of non-delinquent current real property taxes and assessments not yet due and payable, (2) covenants, conditions and restrictions, rights of way, easements and other matters of the public record as of the date of recording which are acceptable to mortgage lending institutions generally and either (A) which are referred to or otherwise considered in the appraisal made for the originator of the Mortgage Loan, or (B) which do not adversely affect the appraised value of the Mortgaged Property as set forth in such appraisal, and (3) other matters to which like properties are commonly subject which do not materially interfere with the benefits of the security intended to be provided by the Mortgage or the use, enjoyment, value or marketability of the related Mortgaged Property. Any security agreement, chattel mortgage or equivalent document related to and delivered in connection with the Mortgage Loan establishes and creates a valid, subsisting, enforceable and perfected first lien and first priority security interest on the property described therein, and the Seller has the full right to sell and assign the same to the Depositor;

(ix)

The Mortgage Note and the related Mortgage are original and genuine and each is the legal, valid and binding obligation of the maker thereof, enforceable in all respects in accordance with its terms subject to bankruptcy, insolvency, moratorium, reorganization and other laws of general application affecting the rights of creditors and by general equitable principles;

(x)

DLJMC or its affiliate is the sole owner of record and holder of the Mortgage Loan and the indebtedness evidenced by the Mortgage Note.  Immediately prior to the transfer and assignment to the Depositor on the Closing Date, the Mortgage Loan, including the Mortgage Note and the Mortgage, were not subject to an assignment or pledge, and DLJMC had good and marketable title to and was the sole owner thereof and had full right to transfer and sell the Mortgage Loan to the Depositor free and clear of any encumbrance, equity, lien, pledge, charge, claim or security interest and has the full right and authority subject to no interest or participation of, or agreement with, any other party, to sell and assign the Mortgage Loan and following the sale of the Mortgage Loan, the Depositor will own such Mortgage Loan free and clear of any encumbrance, equity, participation interest, lien, pledge, charge, claim or security interest;

(xi)

(“DLJMC”), a Delaware corporation, as seller (in such capacity, the “Seller”), WELLS FARGO BANK, N.A.

Capitalized terms used in this Agreement and not otherwise defined will have the meanings assigned to them in Article I below or, if not defined therein, in the Standard Terms.

The terms and provisions of the Standard Terms are hereby incorporated by reference herein as though set forth in full herein.  If any term or provision contained herein shall conflict with or be inconsistent with any provision contained in the Standard Terms, the terms and provisions of this Series Supplement shall govern.  For the avoidance of doubt, any references in the Standard Terms to any servicer that did not either (a) execute this Series Supplement or (b) execute a Designated Servicing Agreement shall be disregarded and have no legal effect.

PRELIMINARY STATEMENT 

As provided herein, the Trust Administrator shall elect that the Trust Fund be treated for federal income tax purposes as comprising two real estate mortgage investment conduits (each a “REMIC” or, in the alternative, “Subsidiary REMIC” and “Master REMIC”).  Each Class of Certificates (other than the Class AR and Class AR-L Certificates, the Exchangeable Certificates and the Exchangeable REMIC Certificates) and each Class of Uncertificated REMIC Interests 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 the Master REMIC for purposes of the REMIC Provisions.  The Class AR-L Certificates represent ownership of the sole class of residual interest in the Subsidiary REMIC for purposes of the REMIC Provisions.  The Master REMIC shall hold as its assets the Class PP Reserve Fund and the several classes of uncertificated Lower Tier Interests in the Subsidiary REMIC, other than the Class LT1-R Interest, and each such Lower Tier Interest is hereby designated as a regular interest in the Subsidiary REMIC.  The Subsidiary REMIC shall hold as its assets the Mortgage Loans 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.

Subsidiary REMIC

If the Subordinate Percentage is greater than or equal to twice the Subordinate Percentage as of the Closing Date for any Distribution Date the Senior Prepayment Percentage will equal (a) prior to the third anniversary of the first Distribution Date, the Senior Percentage plus 50% of the Subordinate Percentage for that Distribution Date and (b) on or after the third anniversary of the first Distribution Date, the Senior Percentage.

Notwithstanding the foregoing, no decrease to the Senior Prepayment Percentage for the Senior Certificates will occur on any Distribution Date as to which that decrease applies if (i) the outstanding aggregate principal balance of the all of the 60-Day Delinquent Mortgage Loans (averaged over the preceding six month period), as a percentage of the Group C-B Balance as of such Distribution Date is equal to or greater than 50% or (ii) cumulative Realized Losses exceed (a) with respect to the Distribution Date on the fifth anniversary of the first Distribution Date, 30% of the Group C-B Balance as of the Closing Date (the “Original Group C-B Balance”), (b) with respect to the Distribution Date on the sixth anniversary of the first Distribution Date, 35% of the Original Group C-B  Component Balance, (c) with respect to the Distribution Date on the seventh anniversary of the first Distribution Date, 40% of the Original Group C-B Balance, (d) with respect to the Distribution Date on the eighth anniversary of the first Distribution Date, 45% of the Original Group C-B Balance and (e) with respect to the Distribution Date on the ninth anniversary of the first Distribution Date, 50% of the related Original Group C-B Balance.

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.

(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 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-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 the 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 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 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.

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 the 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 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 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.

(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 and file, or cause to be prepared and filed, federal and state tax returns (which returns the Trustee shall sign) 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 the Master REMIC) and the Holder of the Class AR-L Certificates (with respect to the 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.

(g)

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).

(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.

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.

All funds in the Class PP Reserve Account shall remain uninvested.

SECTION 4.02

Allocation of Losses.

(a)

The Senior and Group C-B Certificates.  Realized Losses on the Mortgage Loans with respect to any Distribution Date shall be allocated by the Trust Administrator to the Classes of Senior and Group C-B Certificates as follows:

(i)

any Realized Loss on a Mortgage Loan shall be allocated first, to the Group C-B Certificates in decreasing order of their alphanumerical Class designations (beginning with the Class C-B-6 Certificates), until the respective Class Principal Balance of each such Class is reduced to zero, and second, to the Senior Certificates (other than the Notional Amount Certificates), pro rata, on the basis of their respective Class Principal Balances; provided, however, that Realized Losses which would otherwise be allocated to the Class A-3 Certificates, will instead be allocated to the Class A-5 Certificates, until the Class Principal Balance of the Class A-5 Certificates is reduced to zero.

(b)

On each Distribution Date, if the aggregate Class Principal Balance of all Senior and Class C-B Certificates exceeds the aggregate Stated Principal Balance of the Mortgage Loans (after giving effect to distributions of principal and the allocation of all losses to such Certificates on such Distribution Date), such excess will be deemed a principal loss and shall be allocated by the Trust Administrator to the most junior Class of Group C-B Certificates then outstanding, in reduction of its Class Principal Balance.  

(c)

Any allocation by the Trust Administrator of Realized Losses to a Certificate or any reduction in the Certificate Balance of a Certificate pursuant to this Section 4.02 shall be accomplished by reducing its Certificate Balance, immediately following the distributions made on the related Distribution Date in accordance with the definition of “Certificate Balance.”

SECTION 4.03

Recoveries.

(a)

With respect to any Class of Certificates to which a Realized Loss has been allocated (including any such Class for which the related Class Principal Balance has been reduced to zero), the Class Principal Balance of such Class will be increased immediately following the distributions made on such Distribution Date pursuant to Section 4.01, up to the amount of related Recoveries for such Distribution Date as follows:

(i)

first, the Class Principal Balance of each Class of Senior Certificates will be increased pro rata, up to the amount of Net Recovery Realized Losses for each such Class, and

(ii)

second, the Class Principal Balance of Group C-B Certificates will be increased in order of seniority, up to the amount of Net Recovery Realized Losses for each such Class.

(b)

Any increase to the Class Principal Balance of a Class of Certificates shall increase the Certificate Balance of the related Class pro rata in accordance with each Certificate’s Percentage Interest.

SECTION 4.04

Monthly Statements to Certificateholders.

(a)

Not later than each Distribution Date, the Trust Administrator shall prepare and cause to be made available to each Certificateholder, the Master Servicer, each Servicer, the Trustee, the Depositor and each Rating Agency, a statement setting forth with respect to the related distribution: the items listed in Exhibit T-1, other than items (i)(j), (ii)(j), (v)(f), (v)(h), (v)(i), (v)(j), (v)(n), (v)(q), (v)(r), (v)(w), (v)(y), (vii), (viii) and (ix).

For purposes of the information reported in the monthly statement to certificateholders prepared by the Trust Administrator, a Mortgage Loan is considered to be delinquent when a payment due on any Due Date remains unpaid as of the close of business on the next following monthly Due Date.  The determination as to whether a Mortgage Loan falls into this category is made as of the close of business on the last business day of each month.  For example, a Mortgage Loan due for September 1 at the close of business on October 31 would be described as 30 to 59 days delinquent in the November trust and static pool reporting. 

The Trust Administrator’s responsibility for disbursing the above information to the Certificateholders is limited to the availability, timeliness and accuracy of the information derived from the Master Servicer and each Servicer which shall be provided as required in Section 4.05.  

On each Distribution Date, the Trust Administrator shall provide Bloomberg Financial Markets, L.P. (“Bloomberg”) cusip level factors for each Class of Offered Certificates as of such Distribution Date, using a format and media mutually acceptable to the Trust Administrator and Bloomberg.  In connection with providing the information specified in this Section 4.04 to Bloomberg, the Trust Administrator and any director, officer, employee or agent of the Trust Administrator shall be indemnified and held harmless by DLJMC, to the extent, in the manner and subject to the limitations provided in Section 9.05.  The Trust Administrator will also make the monthly statements to Certificateholders available each month to each party referred to in Section 4.04(a) via the Trust Administrator’s website.  The Trust Administrator’s website can be accessed at http://www.ctslink.com or at such other site as the Trust Administrator may designate from time to time.  Persons that are unable to use the above website are entitled to have a paper copy mailed to them via first class mail by calling the Trust Administrator at (866) 846-4526.  The Trust Administrator shall have the right to change the way the reports referred to in this Section are distributed in order to make such distribution more convenient and/or more accessible to the above parties and to the Certificateholders.  The Trust Administrator shall provide timely and adequate notification to all above parties and to the Certificateholders regarding any such change.  The Trust Administrator may fully rely upon and shall have no liability with respect to information provided by the Master Servicer or any Servicer.

SECTION 6.01

The Certificates.

The Certificates, other than the Uncertificated REMIC Interests, shall be in substantially the forms set forth in Exhibits A through H 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 such 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 11.02 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 definitive 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.

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

(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 or any transfer of a Private Certificate from the Depositor or an affiliate of the Depositor to an owner trust or other entity established by the Depositor, 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 M (the “Transferor Certificate”) and such Certificateholder’s prospective transferee shall (i) deliver a letter in substantially the form of either (A) Exhibit N-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, (B) Exhibit N-2 (the “Rule 144A Letter”) or (C) Exhibit N-3 (the “Regulation S 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.  In the event that none of an Investment Letter, a Rule 144A Letter, a Regulation S Letter or an Opinion of Counsel referenced in (ii) above are furnished, such representations shall be deemed to have been made to the Trust Administrator by the transferee’s acceptance of a Private Certificate by any beneficial owner who purchases an interest in such Certificate in book-entry form.  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, the 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)

(i)  No transfer of an ERISA Restricted Certificate shall be made unless the Trust Administrator shall have received in accordance with Exhibit N-1, Exhibit N-2, Exhibit N-3 or Exhibit O, 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 (“Plan”), 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 purchaser 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 a Plan, an Opinion of Counsel satisfactory to the Trust Administrator 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 Modification Oversight Agent, the Trust Administrator, the Master Servicer, the Special Servicer, the Servicers or any other servicers 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 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;

(ii)

The following legend shall appear on each ERISA-Restricted Certificate:

PURSUANT TO SECTION 6.02(f) OF THE AGREEMENT, AN ERISA-RESTRICTED CERTIFICATE OR ANY INTEREST HEREIN MAY ONLY BE TRANSFERRED IF THE TRANSFEREE DELIVERS TO THE TRUSTEE AND THE TRUST ADMINISTRATOR (I) A REPRESENTATION LETTER TO THE EFFECT THAT SUCH TRANSFEREE IS NOT AN EMPLOYEE BENEFIT PLAN OR ARRANGEMENT SUBJECT TO SECTION 406 OF ERISA OR SECTION 4975 OF THE CODE OR A PERSON ACQUIRING SUCH CERTIFICATE FOR, ON BEHALF OF OR WITH THE ASSETS OF SUCH A PLAN OR ARRANGEMENT (“BENEFIT PLAN INVESTOR”) OR (II) IF THE CERTIFICATE IS THE SUBJECT OF AN ERISA-QUALIFYING UNDERWRITING AND THE PURCHASER IS AN INSURANCE COMPANY, A REPRESENTATION IN ACCORDANCE WITH THE PROVISIONS OF THE AGREEMENT REFERRED TO HEREIN OR (III) AN OPINION OF COUNSEL IN ACCORDANCE WITH THE PROVISIONS OF THE AGREEMENT REFERRED TO HEREIN.  IN THE EVENT THE REPRESENTATIONS REFERRED TO IN THE PRECEDING SENTENCE ARE NOT FURNISHED, SUCH REPRESENTATION SHALL BE DEEMED TO HAVE BEEN MADE TO THE TRUSTEE AND THE TRUST ADMINISTRATOR BY THE TRANSFEREE’S ACCEPTANCE OF THIS CERTIFICATE, OR BY ANY BENEFICIAL OWNER WHO PURCHASES AN INTEREST IN THIS CERTIFICATE IN BOOK-ENTRY FORM.  IN THE EVENT THAT A REPRESENTATION IS VIOLATED, OR ANY ATTEMPT TO TRANSFER THIS CERTIFICATE TO A BENEFIT PLAN INVESTOR IS ATTEMPTED WITHOUT THE DELIVERY TO THE TRUST ADMINISTRATOR OF THE OPINION OF COUNSEL DESCRIBED ABOVE, THE ATTEMPTED TRANSFER OR ACQUISITION OF THIS 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:

(1)  

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.

(2)  

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 O) 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 P, 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.

(3)  

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.

(4) 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 P.

(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 P 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:

(1)  

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

(2)  

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.

TERMINATION

SECTION 11.01

Termination upon Liquidation or Purchase of all Mortgage Loans.

The obligations and responsibilities of the Master Servicer, the Special Servicer, the Servicers, the Modification Oversight Agent, the Seller, the Depositor, the Trustee and the Trust Administrator created hereby with respect to the Trust Fund created hereby shall terminate upon the earlier of:

(A)  the purchase by the Terminating Entity, at its election, of all the Mortgage Loans and all property acquired in respect of any remaining Mortgage Loan which purchase right the Terminating Entity may exercise at its sole and exclusive election as of any Distribution Date (such applicable Distribution Date being herein referred to as the “Optional Termination Date”) on or after the date on which the aggregate Principal Balance of the Mortgage Loans, at the time of the purchase is less than 10% of the aggregate Principal Balance of the Mortgage Loans as of the Cut-off Date; or

 (B)

the later of (i) twelve months after the maturity of the last Mortgage Loan remaining in the Trust Fund, (ii) the liquidation (or any advance with respect thereto) of the last Mortgage Loan remaining in the Trust Fund and the disposition of all REO Property and (iii) the distribution to Certificateholders of all amounts required to be distributed to them pursuant to this Agreement; or

(C)

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

In no event shall the trust created hereby continue beyond the earlier of (i) the expiration of 21 years from the death of the last survivor of the descendants of Mr. Joseph P. Kennedy, former Ambassador of the United States to Great Britain, living on the date of execution of this Agreement or (ii) 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 “Mortgage Loan Purchase Price” for any such Optional Termination shall be equal to the greater of (a) the sum of (i) 100% of the Stated Principal Balance of each Mortgage Loan (other than in respect of REO Property) plus accrued and unpaid interest thereon from the date to which such interest was paid or advanced at the sum of the applicable Mortgage Rate, to but not including the Due Date in the month of the final Distribution Date (or the Net Mortgage Rate with respect to any Mortgage Loan currently serviced by the entity exercising such Optional Termination) and (ii) with respect to any REO Property, the lesser of (x) the appraised value of any REO Property as determined by the higher of two appraisals completed by two independent appraisers selected by the Depositor at the expense of the Depositor and (y) the Stated Principal Balance of each Mortgage Loan related to any REO Property, in each case and (iii) any remaining unreimbursed Advances and Servicing Advances and unpaid Servicing Fees, other than any remaining unreimbursed Advances and Servicing Advances and unpaid Servicing Fees, if any, due to the Terminating Entity, and other amounts payable to the Trustee and Trust Administrator (the sum of (i), (ii) and (iii), collectively, the “Par Value”) and (b) the Fair Market Value of all of the property of the Trust.  The “Fair Market Value” shall be the fair market value of all of the property of the Trust subject to an Optional Termination, as agreed upon between the Terminating Entity and a majority of the holders of the Class AR-L Certificates; provided, however, that if the Terminating Entity and a majority of the holders of the Class AR-L Certificates do not agree upon the fair market value of all of such property of the Trust, the Terminating Entity, or an agent appointed by the Terminating Entity, shall solicit bids for all of such property of the Trust until it has received three bids, and the Fair Market Value shall be equal to the highest of such three bids.  The Trust Administrator shall give notice to the Rating Agencies of election to purchase the Mortgage Loans pursuant to this Section 11.01 and of the Optional Termination Date.

On any Distribution Date on or after the date on which the aggregate Principal Balance of the Mortgage Loans at the time of the purchase is less than 5% of the aggregate Principal Balance of the Mortgage Loans as of the Cut-off Date (the “Auction Date”), the Trust Administrator shall solicit bids for the all of the Trust Collateral from at least three institutions that are regular purchasers and/or Seller in the secondary market of residential whole mortgage loans similar to the Mortgage Loans.  If the Trust Administrator receives at least three bids for all of the Trust Collateral, and one of such bids is equal to or greater than the Par Value, the Trust Administrator shall sell all of the Trust Collateral to the highest bidder (the “Auction Purchaser”) at the price offered by the Auction Purchaser (the “Mortgage Loan Auction Price”).  If the Trust Administrator receives less than three bids, or does not receive any bid that is equal to or greater than the Par Value, the Trust Administrator shall, on each six-month anniversary of the initial Auction Date, repeat these auction procedures until the Trust Administrator receives a bid that is equal to or greater than the Par Value, and sells all of the Trust Collateral to the Auction Purchaser at the Mortgage Loan Purchase Price; provided, however, that the Trust Administrator shall not be required to repeat these auction procedures on any Distribution Date for any six-month anniversary of the initial Auction Date unless the Trust Administrator reasonably believes that there is a reasonable likelihood of receiving a bid in excess of the Par Value.  The Trust Administrator shall give notice to the Rating Agencies and each Servicer that is servicing any of the Mortgage Loans of the sale of all of the Trust Collateral pursuant to this Section 11.01 (an “Auction Sale”) and of the Auction Date.  Notwithstanding anything to the contrary herein, the Auction Purchaser shall not be the Depositor or DLJMC or any of their respective affiliates.

SECTION 11.02

Determination of the Terminating Entity

(a)

If any Servicer intends to be the Terminating Entity, such party must give written notice to the Trust Administrator no later than twenty (20) days prior to the first day of the Optional Termination Notice Period.  Upon receiving such notice, the Trust Administrator shall immediately request from DLJMC and DLJMC shall deliver no later than seventeen (17) days prior to the first day of the Optional Termination Notice Period a letter indicating whether or not DLJMC retains the servicing rights to any Mortgage Loan.

(b)

With respect to the purchase of the Mortgage Loans, the Trust Administrator shall determine the “Terminating Entity” as follows:

(i) DLJMC, if it is the owner of the servicing rights with respect to any Mortgage Loan on the Optional Termination Date;

(ii) SPS, if (a) DLJMC is not the owner of the servicing rights with respect to any Mortgage Loan on the Optional Termination Date and (b) SPS is a Servicer with respect to any Mortgage Loan on the Optional Termination Date and SPS has given notice to the Trust Administrator pursuant to Section 11.02(a) above; 

(iii) the Majority Servicer on the Optional Termination Date, if (a) DLJMC is not the owner of the servicing rights with respect to any Mortgage Loan on the Optional Termination Date and (b) SPS has not given notice to the Trust Administrator pursuant to Section 11.02(a) above.

(c)

No later than fifteen (15) days prior to the first day of the Optional Termination Notice Period, the Trust Administrator shall provide notice to each Servicer that is a servicer of any of the Mortgage Loans of the occurrence of the Optional Termination Notice Period and the identity of those parties who may be entitled to be the Terminating Entity.

SECTION 11.03

Procedure Upon Optional Termination or Auction Sale.

(a)

In case of any Optional Termination the Terminating Entity shall, no later than ten (10) days prior to the first day of the Optional Termination Notice Period notify the Trustee and Trust Administrator of such Optional Termination Date and of the applicable purchase price of the Mortgage Loans to be purchased.  Upon the purchase by the Terminating Entity of any Mortgage Loans pursuant to Section 11.01, the Trust Administrator shall notify each Servicer that is servicing any of such Mortgage Loans of such purchase.

(b)

Any purchase of the Mortgage Loans by the Terminating Entity shall be made on an Optional Termination Date by deposit of the applicable purchase price into the Certificate Account, as applicable, before the Distribution Date on which such purchase is effected.  Upon receipt by the Trust Administrator of an Officer’s Certificate of the Terminating Entity certifying as to the deposit of such purchase price into the Certificate Account, the Trustee and the Trust Administrator and each co-trust administrator and separate trust administrator, if any, then acting as such under this Agreement, shall, upon request and at the expense of the Terminating Entity execute and deliver all such instruments of transfer or assignment, in each case without recourse, as shall be reasonably requested by the Terminating Entity  to vest title in the Terminating Entity in the Mortgage Loans so purchased and shall transfer or deliver to the Terminating Entity the purchased Mortgage Loans.  Any distributions on the Mortgage Loans which have been subject to an Optional Termination received by the Trust Administrator subsequent to (or with respect to any period subsequent to) the Optional Termination Date shall be promptly remitted by it to the Terminating Entity.

(c)

Any purchase of the Trust Collateral by the related Auction Purchaser shall be made on an Auction Date by receipt of the Trust Administrator of the related Mortgage Loan Auction Price from the Auction Purchaser, and deposit of the such Mortgage Loan Auction Price into the Certificate Account by the Trust Administrator before the Distribution Date on which such purchase is effected.  Upon deposit of such purchase price into the Certificate Account, the Trustee and the Trust Administrator and each co-trust administrator and separate trust administrator, if any, then acting as such under this Agreement, shall, upon request and at the expense of the Auction Purchaser execute and deliver all such instruments of transfer or assignment, in each case without recourse, as shall be reasonably requested by the Auction Purchaser to vest title in the Auction Purchaser in the Trust Collateral so purchased and shall transfer or deliver to the Auction Purchaser the purchased Trust Collateral.

(d)

Notice of the Distribution Date on which the Trust Administrator anticipates that the final distribution shall be made on a Class of Certificates (whether upon Optional Termination, Auction Sale or otherwise), shall be given promptly by the Trust Administrator by first class mail to Holders of the affected Certificates.  Such notice shall be mailed no earlier than the 15th day and not later than the 10th day preceding the applicable Optional Termination Date, Auction Date or date of final distribution, as the case may be.  Such notice shall specify (i) the Distribution Date upon which final distribution on the affected Certificates will be made upon presentation and surrender of such Certificates at the office or agency therein designated, (ii) the amount of such final distribution and (iii) that the Record Date otherwise applicable to such Distribution Date is not applicable, such distribution being made only upon presentation and surrender of such Certificates at the office or agency maintained for such purposes (the address of which shall be set forth in such notice).

(e)

In the event that any Certificateholders shall not surrender Certificates for cancellation within six months after the date specified in the above mentioned written notice, the Trust Administrator shall give a second written notice to the remaining such Certificateholders to surrender their Certificates for cancellation and receive the final distribution with respect thereto.  If within six months after the second notice all the Certificates shall not have been surrendered for cancellation, the Trust Administrator may take appropriate steps, or may appoint an agent to take appropriate steps, to contact the remaining Certificateholders concerning surrender of their Certificates, and the cost thereof shall be paid out of the funds and other assets which remain subject to the Trust Fund.

(f)

Notwithstanding anything to the contrary herein, the occurrence of an Optional Termination or Auction Sale shall be subject to, and shall in no way adversely affect the right of Bank of America to continue servicing and collecting its Servicing Fee for any Bank of America Serviced Mortgage Loan that remains outstanding at the time of such Optional Termination.

SECTION 11.04

Additional Termination Requirements.

(a)

In the event the Terminating Entity exercises an Optional Termination pursuant to Section 11.01(A) or an Auction Sale pursuant to Section 11.01(C), the REMIC holding the Mortgage Loans shall be liquidated in accordance with the following additional requirements, unless the Trustee and the Trust Administrator have received an Opinion of Counsel to the effect that the failure to comply with the requirements of this Section will not (i) result in the imposition of taxes on a “prohibited transaction” of any REMIC, as described in Section 860F of the Code, or (ii) cause any REMIC formed hereby to fail to qualify as a REMIC at any time that any Certificates are outstanding:

(i)

within 90 days prior to the final Distribution Date set forth in the notice given by the Trust Administrator under Section 11.03, the Holder of the Class AR-L Certificates shall adopt a plan of complete liquidation of the Subsidiary REMIC; and

(ii)

at or after the time of adoption of any such plan of complete liquidation for the Subsidiary REMIC and at or prior to the final Distribution Date, the Trustee shall sell all of the assets of such Subsidiary REMIC to the Terminating Entity for cash; provided, however, that in the event that a calendar quarter ends after the time of adoption of such a plan of complete liquidation but prior to the final Distribution Date, the Trustee shall not sell any of the assets of such REMIC prior to the close of that calendar quarter.

(b)

[Reserved].

(c)

By its acceptance of a Residual Certificate, the Holder thereof hereby agrees to adopt such a plan of complete liquidation and to take such other action in connection therewith as may be reasonably required to liquidate and otherwise terminate the Master REMIC and the Subsidiary REMIC.
