The Class R Certificates will be the sole class of “residual interests” in REMIC I for purposes of the REMIC Provisions (as defined herein). The following table irrevocably sets forth the designation, the Pass-Through Rate, the Initial Certificate Principal Balance and, for purposes of satisfying Treasury regulation Section 1.860G-1(a)(4)(iii), the “latest possible maturity date” for each of the Classes of Certificates that evidence “regular interests” or “residual interests” in REMIC I.

CONVEYANCE OF MORTGAGE LOANS;

ORIGINAL ISSUANCE OF CERTIFICATES

SECTION 2.01

Conveyance of Mortgage Loans.

The Depositor, concurrently with the execution and delivery hereof, does hereby transfer, assign, set over and otherwise convey to the Trustee without recourse for the benefit of the Certificateholders all the right, title and interest of the Depositor, including any security interest therein for the benefit of the Depositor, in and to the Mortgage Loans identified on the Mortgage Loan Schedule, the rights of the Depositor under the Mortgage Loan Purchase Agreement (except Section 18 thereof), and all other assets included or to be included in REMIC I. Such assignment includes all interest and principal received by the Depositor or the Master Servicer on or with respect to the Mortgage Loans (other than payments of principal and interest due on such Mortgage Loans on or before the Cut-off Date). The Depositor herewith delivers to the Trustee or a Custodian on its behalf an executed copy of the Mortgage Loan Purchase Agreement.

In connection with such transfer and assignment, the Depositor does hereby deliver to, and deposit with, the Trustee or a Custodian on its behalf, the following documents or instruments (a “Mortgage File”) with respect to each Mortgage Loan so transferred and assigned:

(i) The Mortgage Note, endorsed by manual or facsimile signature without recourse by the Originator or an Affiliate of the Originator in blank or to the Trustee showing a complete chain of endorsements from the named payee to the Trustee or from the named payee to the Affiliate of the Originator and from such Affiliate to the Trustee;

(ii) The original recorded Mortgage, noting the presence of the MIN of the Mortgage Loan and language indicating that the Mortgage Loan is a MOM Loan if the Mortgage Loan is a MOM Loan, with evidence of recording thereon or a copy of the Mortgage certified by the public recording office in those jurisdictions where the public recording office retains the original;

(iii) Unless the Mortgage Loan is registered on the MERS® System, an assignment to the Trustee in recordable form of the Mortgage which may be included, where permitted by local law, in a blanket assignment or assignments of the Mortgage to the Trustee, including any intervening assignments and showing a complete chain of title from the original mortgagee named under the Mortgage to the Person assigning the Mortgage Loan to the Trustee (or to MERS, noting the presence of the MIN, if the Mortgage Loan is registered on the MERS® System);

(iv) Any original assumption, modification, buydown or conversion-to- fixed-interest-rate agreement applicable to the Mortgage Loan;

(v) With respect to any Mortgage Loan listed on the Mortgage Loan Schedule as subject to a Primary Mortgage Insurance Policy, the original Primary Mortgage Insurance Policy or certificate or a copy thereof; and

(vi) The original or a copy of the title insurance policy (which may be a certificate or a short form policy relating to a master policy of title insurance) pertaining to the Mortgaged Property, or in the event such original title policy is unavailable, a copy of the preliminary title report and the lender’s recording instructions, with the original to be delivered within 180 days of the Closing Date or an attorney’s opinion of title in jurisdictions where such is the customary evidence of title.

In instances where an original recorded Mortgage cannot be delivered by the Depositor to the Trustee (or a Custodian on behalf of the Trustee) prior to or concurrently with the execution and delivery of this Agreement, due to a delay in connection with the recording of such Mortgage, the Depositor may, (a) in lieu of delivering such original recorded Mortgage referred to in clause (ii) above, deliver to the Trustee (or a Custodian on behalf of the Trustee) a copy thereof, provided that the Depositor certifies that the original Mortgage has been delivered to a title insurance company for recordation after receipt of its policy of title insurance or binder therefor (which may be a certificate relating to a master policy of title insurance), and (b) in lieu of delivering the completed assignment in recordable form referred to in clause (iii) above to the Trustee (or a Custodian on behalf of the Trustee), deliver such assignment to the Trustee (or a Custodian on behalf of the Trustee) completed except for recording information. In all such instances, the Depositor will deliver the original recorded Mortgage and completed assignment (if applicable) to the Trustee (or a Custodian on behalf of the Trustee) promptly upon receipt of such Mortgage. In instances where an original recorded Mortgage has been lost or misplaced, the Depositor or the related title insurance company may deliver, in lieu of such Mortgage, a copy of such Mortgage bearing recordation information and certified as true and correct by the office in which recordation thereof was made. In instances where the original or a copy of the title insurance policy referred to in clause (vi) above (which may be a certificate relating to a master policy of title insurance) pertaining to the Mortgaged Property relating to a Mortgage Loan cannot be delivered by the Depositor to the Trustee (or a Custodian on behalf of the Trustee) prior to or concurrently with the execution and delivery of this Agreement because such policy is not yet available, the Depositor may, in lieu of delivering the original or a copy of such title insurance referred to in clause (vi) above, deliver to the Trustee (or a Custodian on behalf of the Trustee) a binder with respect to such policy (which may be a certificate relating to a master policy of title insurance) and deliver the original or a copy of such policy (which may be a certificate relating to a master policy of title insurance) to the Trustee (or a Custodian on behalf of the Trustee) within 180 days of the Closing Date, in instances where an original assumption, modification, buydown or conversion-to-fixed- interest-rate agreement cannot be delivered by the Depositor to the Trustee (or a Custodian on behalf of the Trustee) prior to or concurrently with the execution and delivery of this Agreement, the Depositor may, in lieu of delivering the original of such agreement referred to in clause (iv) above, deliver a certified copy thereof.

To the extent not already recorded, except with respect to any Mortgage Loan for which MERS is identified on the Mortgage or on a properly recorded assignment of the Mortgage as the mortgagee of record, the Master Servicer, at the expense of the Seller shall promptly (and in no event later than five Business Days following the later of the Closing Date and the date of receipt by the Master Servicer of the recording information for a Mortgage) submit or cause to be submitted for recording, at no expense to any Trust REMIC, in the appropriate public office for real property records, each Assignment delivered to it pursuant to

(iii) above. In the event that any such Assignment is lost or returned unrecorded because of a defect therein, the Master Servicer, at the expense of the Seller, shall promptly prepare or cause to be prepared a substitute Assignment or cure or cause to be cured such defect, as the case may be, and thereafter cause each such Assignment to be duly recorded. Notwithstanding the foregoing, but without limiting the requirement that such Assignments be in recordable form, neither the Master Servicer nor the Trustee shall be required to submit or cause to be submitted for recording any Assignment delivered to it or a Custodian pursuant to (iii) above if such recordation shall not, as of the Closing Date, be required by the Rating Agencies, as a condition to their assignment on the Closing Date of their initial ratings to the Certificates, as evidenced by the delivery by the Rating Agencies of their ratings letters on the Closing Date; provided, however, notwithstanding the foregoing, the Master Servicer shall submit each Assignment for recording, at no expense to the Trust Fund or the Master Servicer, upon the earliest to occur of: (A) reasonable direction by Holders of Certificates entitled to at least 25% of the Voting Rights, (B) the occurrence of a Master Servicer Event of Termination, (C) the occurrence of a bankruptcy, insolvency or foreclosure relating to the Seller, (D) the occurrence of a servicing transfer as described in Section 7.02 of this Agreement and (E) with respect to any one Assignment the occurrence of a foreclosure relating to the Mortgagor under the related Mortgage. Notwithstanding the foregoing, if the Seller fails to pay the cost of recording the Assignments, such expense will be paid by the Master Servicer and the Master Servicer shall be reimbursed for such expenses by the Trust as set forth herein.

In connection with the assignment of any Mortgage Loan registered on the MERS System, the Depositor further agrees that it will cause, within 30 Business Days after the Closing Date, the MERS System to indicate that such Mortgage Loans have been assigned by the Depositor to the Trustee in accordance with this Agreement for the benefit of the Certificateholders by including in such computer files (a) the code in the field which identifies the specific Trustee and (b) the code in the field “Pool Field” which identifies the series of the Certificates issued in connection with such Mortgage Loans. The Depositor further agrees that it will not, and will not permit the Master Servicer to, and the Master Servicer agrees that it will not and will not permit a Sub-Servicer to, alter the codes referenced in this paragraph with respect to any Mortgage Loan during the term of this Agreement unless and until such Mortgage Loan is repurchased in accordance with the terms of this Agreement.

With respect to a maximum of approximately 5.00% of the Original Mortgage Loans, by outstanding principal balance of the Original Mortgage Loans as of the Cut-off Date, if any original Mortgage Note referred to in (i) above cannot be located, the obligations of the Depositor to deliver such documents shall be deemed to be satisfied upon delivery to the Trustee (or a Custodian on behalf of the Trustee) of a photocopy of such Mortgage Note, if available, with a lost note affidavit. If any of the original Mortgage Notes for which a lost note affidavit was delivered to the Trustee (or a Custodian on behalf of the Trustee) is subsequently located, such original Mortgage Note shall be delivered to the Trustee (or a Custodian on behalf of the Trustee) within three Business Days.

The Depositor shall deliver or cause to be delivered to the Trustee (or a Custodian on behalf of the Trustee) promptly upon receipt thereof any other original documents constituting a part of a Mortgage File received with respect to any Mortgage Loan, including, but

not limited to, any original documents evidencing an assumption, modification, consolidation or extension of any Mortgage Loan.

All original documents relating to the Mortgage Loans that are not delivered to the Trustee (or a Custodian on behalf of the Trustee) are and shall be held by or on behalf of the Seller, the Depositor or the Master Servicer, as the case may be, in trust for the benefit of the Trustee on behalf of the Certificateholders. In the event that any such original document is required pursuant to the terms of this Section to be a part of a Mortgage File, such document shall be delivered promptly to the Trustee (or a Custodian on behalf of the Trustee). Any such original document delivered to or held by the Depositor that is not required pursuant to the terms of this Section to be a part of a Mortgage File, shall be delivered promptly to the Master Servicer.

Wherever it is provided in this Section 2.01 that any document, evidence or information relating to a Mortgage Loan be delivered or supplied to the Trustee, the Depositor shall do so by delivery thereof to the Trustee or Custodian on behalf of the Trustee.

It is agreed and understood by the parties hereto that it is not intended that any Mortgage Loan to be included in the Trust Fund be (i) a "High-Cost Home Loan" as defined in the New Jersey Home Ownership Act effective November 27, 2003, (ii) a "High-Cost Home Loan" as defined in the New Mexico Home Loan Protection Act effective January 1, 2004, (iii) a "High-Cost Home Mortgage Loan" as defined in the Massachusetts Predatory Home Loan Practices Act effective November 7, 2004 or (iv) a "High Cost Home Loan" as defined in the Indiana Home Loan Practices Act effective January 1, 2005.

SECTION 2.02

Acceptance of the Trust Fund by the Trustee.

Subject to the provisions of Section 2.01 and subject to any exceptions noted on an exception report delivered by or on behalf of the Trustee, the Trustee acknowledges receipt of the documents referred to in Section 2.01 (other than such documents described in Sections 2.01(iv)) and all other assets included in the definition of “Trust Fund” and declares that it holds and will hold such documents and the other documents delivered to it constituting the Mortgage File, and that it holds or will hold all such assets and such other assets included in the definition of “Trust Fund” in trust for the exclusive use and benefit of all present and future Certificateholders.

The Trustee, by execution and delivery hereof, acknowledges receipt, subject to the review described in the succeeding sentence, of the documents and other property referred to in Section 2.01 and declares that the Trustee (or a Custodian on behalf of the Trustee) holds and will hold such documents and other property, including property yet to be received in the Trust Fund, in trust, upon the trusts herein set forth, for the benefit of all present and future Certificateholders. The Trustee or the Custodian on its behalf shall, for the benefit of the Trustee and the Certificateholders, review each Mortgage File within 90 days after execution and delivery of this Agreement, to ascertain that all required documents have been executed, received and recorded, if applicable, and that such documents relate to the Mortgage Loans. If in the course of such review the Trustee or the Custodian on its behalf finds a document or documents constituting a part of a Mortgage File to be defective in any material respect, the Trustee or the

Custodian on its behalf shall promptly so notify the Depositor, the Trust Administrator, the Paying Agent, the Seller, the Master Servicer and, if such notice is from the Custodian on the Trustee’s behalf, the Trustee. In addition, upon the discovery by the Depositor, the Master Servicer, the Trust Administrator, the Paying Agent or the Trustee of a breach of any of the representations and warranties made by the Seller in the Mortgage Loan Purchase Agreement in respect of any Mortgage Loan which materially adversely affects such Mortgage Loan or the interests of the related Certificateholders in such Mortgage Loan, the party discovering such breach shall give prompt written notice to the other parties.

The Depositor and the Trustee intend that the assignment and transfer herein contemplated constitute a sale of the Mortgage Loans, the related Mortgage Notes and the related documents, conveying good title thereto free and clear of any liens and encumbrances, from the Depositor to the Trustee in trust for the benefit of the Certificateholders and that such property not be part of the Depositor’s estate or property of the Depositor in the event of any insolvency by the Depositor. In the event that such conveyance is deemed to be, or to be made as security for, a loan, the parties intend that the Depositor shall be deemed to have granted and does hereby grant to the Trustee a first priority perfected security interest in all of the Depositor’s right, title and interest in and to the Mortgage Loans, the related Mortgage Notes and the related documents, and that this Agreement shall constitute a security agreement under applicable law.

The Trustee may, concurrently with the execution and delivery hereof or at any time thereafter, enter into a custodial agreement with a Custodian pursuant to which the Trustee appoints a Custodian to hold the Mortgage Files on behalf of the Trustee for the benefit of the Trustee and all present and future Certificateholders, which may provide that the Custodian shall, on behalf of the Trustee, conduct the review of each Mortgage File required under the first paragraph of this Section 2.02. Initially, Citibank West, FSB is appointed as Custodian with respect to the Mortgage Files of all the Mortgage Loans and, notwithstanding anything to the contrary herein, it is understood that such initial Custodian shall be responsible for the review contemplated in the second paragraph of this Section 2.02 and for all other functions relating to the receipt, review, reporting and certification provided for herein with respect to the Mortgage Files (other than ownership thereof for the benefit of the Certificateholders and related duties and obligations set forth herein).

SECTION 2.03

Repurchase or Substitution of Mortgage Loans by the Seller or the Depositor.

(a) Upon discovery or receipt of notice by the Depositor, the Master Servicer, the Trust Administrator or the Trustee of any materially defective document in, or that a document is missing from, a Mortgage File or of the breach by the Seller of any representation, warranty or covenant under the Mortgage Loan Purchase Agreement in respect of any Mortgage Loan which materially adversely affects the value of such Mortgage Loan or the interest therein of the Certificateholders, the party so discovering or receiving notice shall promptly notify the other parties to this Agreement, and the Trustee thereupon shall promptly notify the Seller of such defect, missing document or breach and request that the Seller deliver such missing document or cure such defect or breach within 90 days from the date the Seller was notified of such missing document, defect or breach, and if the Seller does not deliver such missing document or cure such defect or breach in all material respects during such period, the Trustee

shall enforce the obligations of the Seller under the Mortgage Loan Purchase Agreement (i) to repurchase such Mortgage Loan from REMIC I at the Purchase Price within 90 days after the date on which the Seller was notified (subject to Section 2.03(e)) of such missing document, defect or breach, and (ii) to indemnify the Trust Fund in respect of such missing document, defect or breach, in the case of each of (i) and (ii), if and to the extent that the Seller is obligated to do so under the Mortgage Loan Purchase Agreement. The Purchase Price for the repurchased Mortgage Loan and any indemnification shall be remitted by the Seller to the Master Servicer for deposit into the Collection Account, and the Trust Administrator, upon receipt of written notice from the Master Servicer of such deposit, shall give written notice to the Trustee that such deposit has taken place and the Trustee shall release (or cause the Custodian to release on its behalf) to the Seller the related Mortgage File, and the Trustee and the Trust Administrator shall execute and deliver such instruments of transfer or assignment, in each case without recourse, as the Seller shall furnish to it and as shall be necessary to vest in the Seller any Mortgage Loan released pursuant hereto, and the Trustee and the Trust Administrator shall have no further responsibility with regard to such Mortgage File. In furtherance of the foregoing, if the Seller is not a member of MERS and repurchases a Mortgage Loan which is registered on the MERS System, the Seller pursuant to the Mortgage Loan Purchase Agreement at its own expense and without any right of reimbursement, shall cause MERS to execute and deliver an assignment of the Mortgage in recordable form to transfer the Mortgage from MERS to the Seller and shall cause such Mortgage to be removed from registration on the MERS System in accordance with MERS rules and regulations. In lieu of repurchasing any such Mortgage Loan as provided above, if so provided in the Mortgage Loan Purchase Agreement the Seller may cause such Mortgage Loan to be removed from REMIC I (in which case it shall become a Deleted Mortgage Loan) and substitute one or more Qualified Substitute Mortgage Loans in the manner and subject to the limitations set forth in Section 2.03(d). It is understood and agreed that the obligation of the Seller to cure or to repurchase (or to substitute for) any Mortgage Loan as to which a document is missing, a material defect in a constituent document exists or as to which such a breach has occurred and is continuing, and if and to the extent provided in the Mortgage Loan Purchase Agreement to perform any applicable indemnification obligations with respect to any such omission, defect or breach, as provided in the Mortgage Loan Purchase Agreement, shall constitute the only remedies respecting such omission, defect or breach available to the Trustee or the Trust Administrator on behalf of the Certificateholders.

(b)

Reserved.

(c) Within 90 days of the earlier of discovery by the Master Servicer or receipt of notice by the Master Servicer of the breach of any representation, warranty or covenant of the Master Servicer set forth in Section 2.05 which materially and adversely affects the interests of the Certificateholders in any Mortgage Loan, the Master Servicer shall cure such breach in all material respects.

(d) Any substitution of Qualified Substitute Mortgage Loans for Deleted Mortgage Loans made pursuant to Section 2.03(a) must be effected prior to the date which is two years after the Startup Day for REMIC I.

As to any Deleted Mortgage Loan for which the Seller substitutes a Qualified Substitute Mortgage Loan or Loans, such substitution shall be effected by the Seller delivering to

the Trustee (or to the Custodian on behalf of the Trustee, as applicable), for such Qualified Substitute Mortgage Loan or Loans, the Mortgage Note, the Mortgage, the Assignment in blank or to the Trustee, and such other documents and agreements, with all necessary endorsements thereon, as are required by Section 2.01, together with an Officers’ Certificate providing that each such Qualified Substitute Mortgage Loan satisfies the definition thereof and specifying the Substitution Shortfall Amount (as described below), if any, in connection with such substitution. The Custodian on its behalf and on behalf of the Trustee shall, for the benefit of the Certificateholders, review each Mortgage File within 90 days after execution and delivery of this Agreement, to ascertain that all required documents have been executed, received and recorded, if applicable, and that such documents relate to the Mortgage Loans. If in the course of such review the Trustee or the Custodian on its behalf finds a document or documents constituting a part of a Mortgage File to be defective in any material respect, the Trustee or the Custodian on its behalf shall promptly so notify the Depositor, the Trust Administrator, the Seller and the Master Servicer. Monthly Payments due with respect to Qualified Substitute Mortgage Loans in the month of substitution are not part of the Trust Fund and will be retained by the Seller. For the month of substitution, distributions to Certificateholders will reflect the Monthly Payment due on such Deleted Mortgage Loan on or before the Due Date in the month of substitution, and the Seller shall thereafter be entitled to retain all amounts subsequently received in respect of such Deleted Mortgage Loan. The Trust Administrator shall give or cause to be given written notice to the Trustee and the Certificateholders that such substitution has taken place, and the Trust Administrator shall amend or cause the Custodian to amend the Mortgage Loan Schedule to reflect the removal of such Deleted Mortgage Loan from the terms of this Agreement and the substitution of the Qualified Substitute Mortgage Loan or Loans and, upon receipt thereof, shall deliver a copy of such amended Mortgage Loan Schedule to the Master Servicer. Upon such substitution, such Qualified Substitute Mortgage Loan or Loans shall constitute part of the mortgage pool and shall be subject in all respects to the terms of this Agreement and the Mortgage Loan Purchase Agreement (including all applicable representations and warranties thereof included in the Mortgage Loan Purchase Agreement), in each case as of the date of substitution.

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 will determine the amount (the “Substitution Shortfall Amount”), if any, by which the aggregate Purchase Price of all such Deleted Mortgage Loans exceeds the aggregate of, as to each such Qualified Substitute Mortgage Loan, the Scheduled Principal Balance thereof as of the date of substitution, together with one month’s interest on such Scheduled Principal Balance at the applicable Mortgage Loan Remittance Rate. On the date of such substitution, the Trustee will monitor the obligation of the Seller to deliver or cause to be delivered, and shall request that such delivery be to the Master Servicer for deposit in the Collection Account, an amount equal to the Substitution Shortfall Amount, if any, and the Trustee (or the Custodian on behalf of the Trustee, as applicable), upon receipt of the related Qualified Substitute Mortgage Loan or Loans and written notice given by the Master Servicer of such deposit, shall release to the Seller the related Mortgage File or Files and the Trustee and the Trust Administrator shall execute and deliver such instruments of transfer or assignment, in each case without recourse, as the Seller shall deliver to it and as shall be necessary to vest therein any Deleted Mortgage Loan released pursuant hereto.

In addition, the Seller shall obtain at its own expense and deliver to the Trustee and the Trust Administrator an Opinion of Counsel to the effect that such substitution will not cause (a) any federal tax to be imposed on any Trust REMIC, including without limitation, any federal tax imposed on “prohibited transactions” under Section 860F(a)(1) of the Code or on “contributions after the startup date” under Section 860G(d)(1) of the Code, or (b) any Trust REMIC to fail to qualify as a REMIC at any time that any Certificate is outstanding.

(e) Upon discovery by the Depositor, the Master Servicer, the Trust Administrator or the Trustee that any Mortgage Loan does not constitute a “qualified mortgage” within the meaning of Section 860G(a)(3) of the Code, the party discovering such fact shall within two Business Days give written notice thereof to the other parties to this Agreement, and the Trustee shall give written notice thereof to the Seller. In connection therewith, the Seller pursuant to the Mortgage Loan Purchase Agreement or the Depositor pursuant to this Agreement shall repurchase or, subject to the limitations set forth in Section 2.03(d), substitute one or more Qualified Substitute Mortgage Loans for the affected Mortgage Loan within 90 days of the earlier of discovery or receipt of such notice with respect to such affected Mortgage Loan. Such repurchase or substitution shall be made by (i) the Seller if the affected Mortgage Loan’s status as a non-qualified mortgage is or results from a breach of any representation, warranty or covenant made by the Seller under the Mortgage Loan Purchase Agreement or (iii) the Depositor, if the affected Mortgage Loan’s status as a non-qualified mortgage is a breach of no representation or warranty. Any such repurchase or substitution shall be made in the same manner as set forth in Sections 2.03(a). The Trustee shall reconvey to the Depositor or the Seller, as the case may be, the Mortgage Loan to be released pursuant hereto in the same manner, and on the same terms and conditions, as it would a Mortgage Loan repurchased by the Seller for breach of a representation or warranty.

The Trustee acknowledges receipt of REMIC I and declares that it holds and will hold the same in trust for the exclusive use and benefit of all present and future Class R Certificateholders and the Holders of the Regular Certificates evidencing interests in REMIC I. The rights of the Class R Certificateholders and the Holders of the Regular Certificates evidencing interests in REMIC I to receive distributions from the proceeds of REMIC I, and all ownership interests evidenced or constituted by the Class R Certificates and the Regular Certificates evidencing interests in REMIC I, shall be as set forth in this Agreement.

ARTICLE III

ADMINISTRATION AND SERVICING

OF THE MORTGAGE LOANS

SECTION 3.01

Master Servicer to Act as Master Servicer.

The Master Servicer shall service and administer the Mortgage Loans on behalf of the Trustee and in the best interests of and for the benefit of the Certificateholders (as determined by the Master Servicer in its reasonable judgment) in accordance with the terms of this Agreement and the respective Mortgage Loans and, to the extent consistent with such terms, in the same manner in which it services and administers similar mortgage loans for its own portfolio, giving due consideration to customary and usual standards of practice of prudent mortgage lenders and loan servicers administering similar mortgage loans but without regard to:

(i) any relationship that the Master Servicer, any Sub-Servicer or any Affiliate of the Master Servicer or any Sub-Servicer may have with the related Mortgagor;

(ii) the ownership of any Certificate by the Master Servicer or any Affiliate of the Master Servicer;

(iii) the Master Servicer’s obligation to make P&I Advances or Servicing Advances; or

(iv) the Master Servicer’s or any Sub-Servicer’s right to receive compensation for its services hereunder or with respect to any particular transaction.

To the extent consistent with the foregoing, the Master Servicer shall also seek to maximize the timely and complete recovery of principal and interest on the Mortgage Notes. Subject only to the above-described servicing standards and the terms of this Agreement and of the respective Mortgage Loans, the Master Servicer shall have full power and authority, acting alone or through Sub-Servicers as provided in Section 3.02, to do or cause to be done any and all things in connection with such servicing and administration which it may deem necessary or desirable. Without limiting the generality of the foregoing, the Master Servicer in its own name or in the name of a Sub-Servicer is hereby authorized and empowered by the Trustee when the Master Servicer believes it appropriate in its best judgment in accordance with the servicing standards set forth above, to execute and deliver, on behalf of the Certificateholders and the Trustee, and upon notice to the Trustee, 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 the Mortgaged Properties and to institute foreclosure proceedings or obtain a deed-in-lieu of foreclosure so as to convert the ownership of such properties, and to hold or cause to be held title to such properties, on behalf of the Trustee and Certificateholders. The Master Servicer shall service and administer the Mortgage Loans in accordance with applicable state and federal law and shall provide to the Mortgagors any reports required to be provided to them thereby. The Master Servicer shall also comply in the performance of this Agreement with all reasonable rules and requirements of each insurer under each Primary Mortgage Insurance Policy and any standard hazard insurance policy. Subject to Section 3.17, the Trustee shall execute, at the written request of the Master Servicer, and furnish to the Master Servicer and any Sub-Servicer such documents as are necessary or appropriate to enable the Master Servicer or any Sub-Servicer to carry out their servicing and administrative duties hereunder, and the Trustee hereby grants to the Master Servicer a power of attorney to carry out such duties. The Trustee shall not be liable for the actions of the Master Servicer or any Sub-Servicers under such powers of attorney.

In accordance with the standards of the preceding paragraph, the Master Servicer shall advance or cause to be advanced funds as necessary for the purpose of effecting the timely payment of taxes and assessments on the Mortgaged Properties, which advances shall be Servicing Advances reimbursable in the first instance from related collections from the Mortgagors pursuant to Section 3.09, and further as provided in Section 3.11. Any cost incurred by the Master Servicer or by Sub- Servicers in effecting the timely payment of taxes and assessments on a Mortgaged Property shall not, for the purpose of calculating distributions to Certificateholders, be added to the unpaid principal balance of the related Mortgage Loan, notwithstanding that the terms of such Mortgage Loan so permit.

The Master Servicer further is authorized and empowered by the Trustee, on behalf of the Certificateholders and the Trustee, in its own name or in the name of the Sub-Servicer, when the Master Servicer or the Sub-Servicer, as the case may be, believes it is 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 reasonable expenses (i) incurred as a result of MERS discontinuing or becoming unable to continue operations in connection with the MERS System or (ii) if the affected Mortgage Loan is in default or, in the judgment of the Master Servicer, such default is reasonably foreseeable, incurred in connection with the actions described in the preceding sentence, shall be subject to withdrawal by the Master Servicer from the Collection Account.

Notwithstanding anything in this Agreement to the contrary, the Master Servicer may not make any future advances with respect to a Mortgage Loan (except as provided in Section 4.03) and the Master Servicer shall not (i) permit any modification with respect to any Mortgage Loan (except with respect to a Mortgage Loan that is in default or, in the judgment of the Master Servicer, such default is reasonably foreseeable) that would change the Mortgage Rate, reduce or increase the principal balance (except for reductions resulting from actual payments of principal) or change the final maturity date on such Mortgage Loan or (ii) permit any modification, waiver or amendment of any term of any Mortgage Loan that would both (A) effect an exchange or reissuance of such Mortgage Loan under Section 1001 of the Code (or final, temporary or proposed Treasury regulations promulgated thereunder) and (B) cause any Trust REMIC to fail to qualify as a REMIC under the Code or the imposition of any tax on “prohibited transactions” or “contributions after the startup date” under the REMIC Provisions.

The Master Servicer may delegate its responsibilities under this Agreement; provided, however, that no such delegation shall release the Master Servicer from the responsibilities or liabilities arising under this Agreement.

The Master Servicer shall accurately and fully report (or cause each Sub-Servicer to accurately and fully report), its borrower credit files to each of the credit repositories in a timely manner.

SECTION 3.02

Sub-Servicing Agreements Between the Master Servicer and Sub-Servicers.

(a) The Master Servicer may enter into Sub-Servicing Agreements (provided that such agreements would not result in a withdrawal or a downgrading by the Rating Agencies of the rating on any Class of Certificates) with Sub-Servicers, for the servicing and administration of the Mortgage Loans. As of the Cut-Off Date, Wells Fargo is the Sub-Servicer with respect to the Mortgage Loans originated by Wells Fargo and in such capacity Wells Fargo will be primarily responsible for the servicing of such Mortgage Loans. As of the Cut-Off Date, National City is the Sub-Servicer with respect to the National City Mortgage Loans and in such capacity National City will be primarily responsible for the servicing of such Mortgage Loans.

(b) Each Sub-Servicer shall be (i) authorized to transact business in the state or states in which the related Mortgaged Properties it is to service are situated, if and to the extent required by applicable law to enable the Sub-Servicer to perform its obligations hereunder and under the Sub-Servicing Agreement, (ii) an institution approved as a mortgage loan originator by the Federal Housing Administration or an institution the deposit accounts of which are insured by the FDIC and (iii) a Freddie Mac or Fannie Mae approved mortgage servicer.

Each Sub-Servicing Agreement must impose on the Sub-Servicer requirements conforming to the provisions set forth in Section 3.08 and provide for servicing of the Mortgage Loans consistent with the terms of this Agreement. The Master Servicer will examine each Sub-Servicing Agreement and will be familiar with the terms thereof. The terms of any Sub-Servicing Agreement will not be inconsistent with any of the provisions of this Agreement. The Master Servicer and the Sub-Servicers may enter into and make amendments to the Sub-Servicing Agreements or enter into different forms of Sub-Servicing Agreements; provided, however, that any such amendments or different forms shall be consistent with and not violate the provisions of this Agreement, and that no such amendment or different form shall be made or entered into which could be reasonably expected to be materially adverse to the interests of the Certificateholders, without the consent of the Holders of Certificates entitled to at least 66% of the Voting Rights. Any variation without the consent of the Holders of Certificates entitled to at least 66% of the Voting Rights from the provisions set forth in Section 3.08 relating to insurance or priority requirements of Sub-Servicing Accounts, or credits and charges to the Sub- Servicing Accounts or the timing and amount of remittances by the Sub-Servicers to the Master Servicer, are conclusively deemed to be inconsistent with this Agreement and therefore prohibited. The Master Servicer shall deliver to the Trustee and the Trust Administrator copies of all Sub-Servicing Agreements, and any amendments or modifications thereof, promptly upon the Master Servicer’s execution and delivery of such instruments.

(c) As part of its servicing activities hereunder, the Master Servicer (except as otherwise provided in the last sentence of this paragraph), for the benefit of the Trustee and the Certificateholders, shall enforce the obligations of each Sub-Servicer under the related Sub-Servicing Agreement and of the Seller under the Mortgage Loan Purchase Agreement, including, without limitation, any obligation to make advances in respect of delinquent payments as required by a Sub- Servicing Agreement, or to purchase a Mortgage Loan on account of missing or defective documentation or on account of a breach of a representation, warranty or covenant, as described in Section 2.03(a). Such enforcement, including, without limitation, the legal prosecution of claims, termination of Sub-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, and shall be reimbursed therefor only (i) from a general recovery resulting from such enforcement, to the extent, if any, that such recovery exceeds all amounts due in respect of the related Mortgage Loans, or (ii) from a specific recovery of costs, expenses or attorneys’ fees against the party against whom such enforcement is directed.

SECTION 3.03

Successor Sub-Servicers.

The Master Servicer shall be entitled to terminate any Sub-Servicing Agreement and the rights and obligations of any Sub-Servicer pursuant to any Sub-Servicing Agreement in accordance with the terms and conditions of such Sub-Servicing Agreement. In the event of termination of any Sub-Servicer, all servicing obligations of such Sub-Servicer shall be assumed simultaneously by the Master Servicer without any act or deed on the part of such Sub-Servicer or the Master Servicer, and the Master Servicer either shall service directly the related Mortgage Loans or shall enter into a Sub-Servicing Agreement with a successor Sub-Servicer which qualifies under Section 3.02.

Any Sub-Servicing Agreement (other than any Initial Sub-Servicing Agreement) shall include the provision that such agreement may be immediately terminated by the Trustee or the Trust Administrator without fee, in accordance with the terms of this Agreement, in the event that the Master Servicer shall, for any reason, no longer be the Master Servicer (including termination due to a Master Servicer Event of Default).

SECTION 3.04

Liability of the Master Servicer.

Notwithstanding any Sub-Servicing Agreement, any of the provisions of this Agreement relating to agreements or arrangements between the Master Servicer and a Sub-Servicer or reference to actions taken through a Sub-Servicer or otherwise, the Master Servicer shall remain obligated and primarily liable to the Trustee and the Certificateholders for the servicing and administering of the Mortgage Loans in accordance with the provisions of Section 3.01 without diminution of such obligation or liability by virtue of such Sub-Servicing Agreements or arrangements or by virtue of indemnification from the Sub-Servicer and to the same extent and under the same terms and conditions as if the Master Servicer alone were servicing and administering the Mortgage Loans. The Master Servicer shall be entitled to enter into any agreement with a Sub- Servicer for indemnification of the Master Servicer by such Sub-Servicer and nothing contained in this Agreement shall be deemed to limit or modify such indemnification.

SECTION 3.05

No Contractual Relationship Between Sub-Servicers and Trustee, Trust Administrator or Certificateholders.

Any Sub-Servicing Agreement that may be entered into and any transactions or services relating to the Mortgage Loans involving a Sub-Servicer in its capacity as such shall be deemed to be between the Sub-Servicer and the Master Servicer alone, and the Trustee, the Trust Administrator and the Certificateholders shall not be deemed parties thereto and shall have no claims, rights, obligations, duties or liabilities with respect to the Sub-Servicer except as set forth in Section 3.06. The Master Servicer shall be solely liable for all fees owed by it to any Sub-Servicer, irrespective of whether the Master Servicer’s compensation pursuant to this Agreement is sufficient to pay such fees.

SECTION 3.06

Assumption or Termination of Sub-Servicing Agreements by Trustee.

In the event the Master Servicer shall for any reason no longer be the master servicer (including by reason of the occurrence of a Master Servicer Event of Default), the Trustee or its designee shall thereupon assume all of the rights and obligations of the Master Servicer under each Sub-Servicing Agreement that the Master Servicer may have entered into, unless the Trustee elects to terminate any Sub-Servicing Agreement in accordance with its terms as provided in Section 3.03. Upon such assumption, the Trustee, its designee or the successor servicer for the Trustee appointed pursuant to Section 7.02 shall be deemed, subject to Section 3.03, to have assumed all of the Master Servicer’s interest therein and to have replaced the Master Servicer as a party to each Sub-Servicing Agreement to the same extent as if each Sub-Servicing Agreement had been assigned to the assuming party, except that (i) the Master Servicer shall not thereby be relieved of any liability or obligations under any Sub-Servicing

Agreement and (ii) none of the Trustee, its designee or any successor Master Servicer shall be deemed to have assumed any liability or obligation of the Master Servicer that arose before it ceased to be the Master Servicer.

The Master Servicer at its expense shall, upon request of the Trustee, deliver to the assuming party all documents and records relating to each Sub-Servicing Agreement and the Mortgage Loans then being serviced and an accounting of amounts collected and held by or on behalf of it, and otherwise use its best efforts to effect the orderly and efficient transfer of the Sub- Servicing Agreements to the assuming party.

SECTION 3.07

Collection of Certain Mortgage Loan Payments.

The Master Servicer shall make reasonable efforts to collect all payments called for under the terms and provisions of the Mortgage Loans, and shall, to the extent such procedures shall be consistent with this Agreement and the terms and provisions of any related Primary Mortgage Insurance Policy and any other applicable insurance policies, follow such collection procedures as it would follow with respect to mortgage loans comparable to the Mortgage Loans and held for its own account. Consistent with the foregoing and the servicing standards set forth in Section 3.01, the Master Servicer may in its discretion (i) waive any late payment charge or, if applicable, penalty interest, only upon determining that the coverage of such Mortgage Loan by the related Primary Mortgage Insurance Policy, if any, will not be affected, or (ii) extend the due dates for Monthly Payments due on a Mortgage Note for a period of not greater than 180 days; provided that any extension pursuant to clause (ii) above shall not affect the amortization schedule of any Mortgage Loan for purposes of any computation hereunder, except as provided below. In the event of any such arrangement pursuant to clause (ii) above, the Master Servicer shall make timely advances on such Mortgage Loan during such extension pursuant to Section 4.03 and in accordance with the amortization schedule of such Mortgage Loan without modification thereof by reason of such arrangements. Notwithstanding the foregoing, in the event that any Mortgage Loan is in default or, in the judgment of the Master Servicer, such default is reasonably foreseeable, the Master Servicer, consistent with the standards set forth in Section 3.01, may waive, modify or vary any term of such Mortgage Loan (including modifications that change the Mortgage Rate, forgive the payment of principal or interest or extend the final maturity date of such Mortgage Loan), accept payment from the related Mortgagor of an amount less than the Stated Principal Balance in final satisfaction of such Mortgage Loan (such payment, a “Short Pay-off”) or consent to the postponement of strict compliance with any such term or otherwise grant indulgence to any Mortgagor, if in the Master Servicer’s determination such waiver, modification, postponement or indulgence is not materially adverse to the interests of the Certificateholders (taking into account any estimated Realized Loss that might result absent such action).

SECTION 3.08

Sub-Servicing Accounts.

In those cases where a Sub-Servicer is servicing a Mortgage Loan pursuant to a Sub-Servicing Agreement, the Sub-Servicer will be required to establish and maintain one or more accounts (collectively, the “Sub-Servicing Account”). The Sub-Servicing Account shall be an Eligible Account and shall comply with all requirements of this Agreement relating to the Collection Account (provided, however, that in the case of each Initial Sub-Servicing

Agreement, the applicable Sub-Servicing Account shall comply with all requirements of the Initial Sub-Servicing Agreement relating to the custodial account provided for therein). The Sub-Servicer shall deposit in the clearing account (which account must be an Eligible Account) in which it customarily deposits payments and collections on mortgage loans in connection with its mortgage loan servicing activities on a daily basis, and in no event more than two Business Days after the Sub-Servicer’s receipt thereof, all proceeds of Mortgage Loans received by the Sub-Servicer less its servicing compensation to the extent permitted by the Sub-Servicing Agreement, and shall thereafter deposit such amounts in the Sub-Servicing Account, in no event more than one Business Day after the deposit of such funds into the clearing account. The Sub-Servicer shall thereafter remit such proceeds to the Master Servicer for deposit in the Collection Account not later than two Business Days after the deposit of such amounts in the Sub-Servicing Account (or, in the case of the Initial Sub-Servicing Agreement, at such time as is required pursuant to the terms of the Initial Sub-Servicing Agreement). For purposes of this Agreement, the Master Servicer shall be deemed to have received payments on the Mortgage Loans when the Sub-Servicer receives such payments.

SECTION 3.09

Collection of Taxes, Assessments and Similar Items; Servicing Accounts.

The Master Servicer shall establish and maintain (or cause a Sub-Servicer to establish and maintain) one or more accounts (the “Servicing Accounts”), into which all collections from the Mortgagors (or related advances from Sub-Servicers) for the payment of ground rents, taxes, assessments, fire and hazard insurance premiums, Primary Mortgage Insurance Premiums, water charges, sewer rents and comparable items for the account of the Mortgagors (“Escrow Payments”) shall be deposited and retained. Servicing Accounts shall be Eligible Accounts. The Master Servicer (or the applicable Sub-Servicer) shall deposit in the clearing account (which account must be an Eligible Account) in which it customarily deposits payments and collections on mortgage loans in connection with its mortgage loan servicing activities on a daily basis, and in no event more than two Business Days after the Master Servicer’s (or the applicable Sub-Servicer’s) receipt thereof, all Escrow Payments collected on account of the Mortgage Loans and shall thereafter deposit such Escrow Payments in the Servicing Accounts, in no event more than one Business Day after the deposit of such funds in the clearing account, for the purpose of effecting the payment of any such items as required under the terms of this Agreement. Withdrawals of amounts from a Servicing Account may be made only to (i) effect payment of Escrow Payments; (ii) reimburse the Master Servicer (or a Sub-Servicer to the extent provided in the related Sub-Servicing Agreement) out of related collections for any advances made pursuant to Section 3.01 (with respect to taxes and assessments) and Section 3.14 (with respect to hazard insurance); (iii) refund to Mortgagors any sums as may be determined to be overages; (iv) pay interest, if required and as described below, to Mortgagors on balances in the Servicing Account; (v) clear and terminate the Servicing Account at the termination of the Master Servicer’s obligations and responsibilities in respect of the Mortgage Loans under this Agreement in accordance with Article IX; or (vi) recover amounts deposited in error. As part of its servicing duties, the Master Servicer or Sub-Servicers shall pay to the Mortgagors interest on funds in Servicing Accounts, to the extent required by law and, to the extent that interest earned on funds in the Servicing Accounts is insufficient, to pay such interest from its or their own funds, without any reimbursement therefor. To the extent that a Mortgage does not provide for Escrow Payments, the Master Servicer shall determine

whether any such payments are made by the Mortgagor in a manner and at a time that avoids the loss of the Mortgaged Property due to a tax sale or the foreclosure of a tax lien. The Master Servicer assumes full responsibility for the payment of all such bills and shall effect payments of all such bills irrespective of the Mortgagor’s faithful performance in the payment of same or the making of the Escrow Payments and shall make advances from its own funds to effect such payments.

SECTION 3.10

Collection Account and Distribution Account.

(a) On behalf of the Trust Fund, the Master Servicer shall establish and maintain one or more separate, segregated trust accounts (such account or accounts, the “Collection Account”), held in trust for the benefit of the Trustee and the Certificateholders. On behalf of the Trust Fund, the Master Servicer shall deposit or cause to be deposited in the clearing account (which account must be an Eligible Account) in which it customarily deposits payments and collections on mortgage loans in connection with its mortgage loan servicing activities on a daily basis, and in no event more than two Business Days after the Master Servicer’s receipt thereof, and shall thereafter deposit in the Collection Account, in no event more than one Business Day after the deposit of such funds into the clearing account, as and when received or as otherwise required hereunder, the following payments and collections received or made by it from and after the Cut-off Date (other than in respect of principal or interest on the related Mortgage Loans due on or before the Cut-off Date), or payments (other than Principal Prepayments) received by it on or prior to the Cut-off Date but allocable to a Due Period subsequent thereto:

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

(ii) all payments on account of interest (net of the related Servicing Fee and the related Administration Fee) on each Mortgage Loan;

(iii) all Insurance Proceeds, Subsequent Recoveries and Liquidation Proceeds (other than proceeds collected in respect of any particular REO Property and amounts paid by the Master Servicer in connection with a purchase of Mortgage Loans and REO Properties pursuant to Section 9.01);

(iv) any amounts required to be deposited pursuant to Section 3.12 in connection with any losses realized on Permitted Investments with respect to funds held in the Collection Account;

(v) any amounts required to be deposited by the Master Servicer pursuant to the second paragraph of Section 3.14(a) in respect of any blanket policy deductibles;

(vi) all proceeds of any Mortgage Loan repurchased or purchased in accordance with Section 2.03 or Section 9.01; and

(vii) all amounts required to be deposited in connection with shortfalls in principal amount of Qualified Substitute Mortgage Loans pursuant to Section 2.03.

For purposes of the immediately preceding sentence, the Cut-off Date with respect to any Qualified Substitute Mortgage Loan shall be deemed to be the date of substitution.

The foregoing requirements for deposit in the Collection Accounts shall be exclusive, it being understood and agreed that, without limiting the generality of the foregoing, payments in the nature of late payment charges or assumption fees need not be deposited by the Master Servicer in the Collection Account. In the event the Master Servicer shall deposit in the Collection Account any amount not required to be deposited therein, it may at any time withdraw such amount from the Collection Account, any provision herein to the contrary notwithstanding.

(b) On behalf of the Trust Fund, the Paying Agent on behalf of the Trust Administrator shall establish and maintain one or more separate, segregated trust accounts (such account or accounts, the “Distribution Account”), held in trust for the benefit of the Certificateholders. On behalf of the Trust Fund, the Master Servicer shall deliver to the Paying Agent in immediately available funds for deposit in the Distribution Account on or before 12:00 p.m. New York time (i) on the Master Servicer Remittance Date, that portion of the Available Distribution Amount (calculated without regard to the subtraction therefrom of the Credit Risk Manager fee or of any amounts described in clause (ii)(a) of the definition thereof) for the related Distribution Date then on deposit in the Collection Account, and (ii) on each Business Day as of the commencement of which the balance on deposit in the Collection Account exceeds $75,000 following any withdrawals pursuant to the next succeeding sentence, the amount of such excess, but only if the Collection Account constitutes an Eligible Account solely pursuant to clause (ii) of the definition of “Eligible Account.” If the balance on deposit in the Collection Account exceeds $75,000 as of the commencement of business on any Business Day and the Collection Account constitutes an Eligible Account solely pursuant to clause (ii) of the definition of “Eligible Account,” the Master Servicer shall, on or before 12:00 p.m. New York time on such Business Day, withdraw from the Collection Account any and all amounts payable or reimbursable to the Depositor, the Master Servicer, the Trustee, the Trust Administrator, the Seller or any Sub-Servicer pursuant to Section 3.11 and shall pay such amounts to the Persons entitled thereto.

(c) Funds in the Collection Account and the Distribution Account may be invested in Permitted Investments in accordance with the provisions set forth in Section 3.12. The Master Servicer shall give notice to the Trustee, the Trust Administrator, the Paying Agent and the Depositor of the location of the Collection Account maintained by it when established and prior to any change thereof. The Paying Agent shall give notice to the Master Servicer, the Trust Administrator, the Paying Agent and the Depositor of the location of the Distribution Account when established and prior to any change thereof.

(d) Funds held in the Collection Account at any time may be delivered by the Master Servicer to the Paying Agent on behalf of the Trust Administrator for deposit in an account (which may be the Distribution Account and must satisfy the standards for the Distribution Account as set forth in the definition thereof) and for all purposes of this Agreement shall be deemed to be a part of the Collection Account; provided, however, that the Paying Agent

shall have the sole authority to withdraw any funds held pursuant to this subsection (d). In the event the Master Servicer shall deliver to the Paying Agent for deposit in the Distribution Account any amount not required to be deposited therein, it may at any time request that the Paying Agent withdraw such amount from the Distribution Account and remit to it any such amount, any provision herein to the contrary notwithstanding. In addition, the Master Servicer shall deliver to the Paying Agent from time to time for deposit, and upon written notification from the Master Servicer, the Paying Agent shall so deposit, in the Distribution Account:

(i)	any P&I Advances, as required pursuant to Section 4.03;

(ii) any amounts required to be deposited pursuant to Section 3.23(d) or (f) in connection with any REO Property;

(iii) any amounts to be paid by the Master Servicer in connection with a purchase of Mortgage Loans and REO Properties pursuant to Section 9.01;

(iv) any amounts required to be deposited pursuant to Section 3.24 in connection with any Prepayment Interest Shortfalls; and

(v) any Stayed Funds, as soon as permitted by the federal bankruptcy court having jurisdiction in such matters.

(e) Promptly upon receipt of any Stayed Funds, whether from the Master Servicer, a trustee in bankruptcy, or federal bankruptcy court or other source, the Paying Agent shall deposit such funds in the Distribution Account, subject to withdrawal thereof as permitted hereunder.

(f) The Master Servicer shall deposit in the Collection Account any amounts required to be deposited pursuant to Section 3.12(b) in connection with losses realized on Permitted Investments with respect to funds held in the Collection Account.

SECTION 3.11

Withdrawals from the Collection Account and Distribution Account.

(a) The Master Servicer shall, from time to time, make withdrawals from the Collection Account for any of the following purposes or as described in Section 4.03:

(i) to remit to the Paying Agent for deposit in the Distribution Account the amounts required to be so remitted pursuant to Section 3.10(b) or permitted to be so remitted pursuant to the first sentence of Section 3.10(d);

(ii) subject to Section 3.16(d), to reimburse the Master Servicer for P&I Advances, but only to the extent of amounts received which represent Late Collections (net of the related Servicing Fees and Administration Fees) of Monthly Payments on Mortgage Loans with respect to which such P&I Advances were made in accordance with the provisions of Section 4.03;

(iii) subject to Section 3.16(d), to pay the Master Servicer or any Sub- Servicer (A) any unpaid Servicing Fees and unpaid Administration Fees, (B) any unreimbursed Servicing Advances with respect to each Mortgage Loan, but only to the extent of any Liquidation Proceeds, Insurance Proceeds or other amounts as may be collected by the Master Servicer from a Mortgagor, or otherwise received with respect to such Mortgage Loan and (C) any nonrecoverable Servicing Advances following the final liquidation of a Mortgage Loan, but only to the extent that Late Collections, Liquidation Proceeds and Insurance Proceeds received with respect to such Mortgage Loan are insufficient to reimburse the Master Servicer or any Sub-Servicer for such Servicing Advances;

(iv) to pay to the Master Servicer as servicing compensation (in addition to the Servicing Fee and the Administration Fee) on the Master Servicer Remittance Date any interest or investment income earned on funds deposited in the Collection Account;

(v) to pay to the Master Servicer, the Depositor or the Seller, as the case may be, with respect to each Mortgage Loan that has previously been purchased or replaced pursuant to Section 2.03 or Section 3.16(c) all amounts received thereon subsequent to the date of purchase or substitution, as the case may be;

(vi) to reimburse the Master Servicer for any P&I Advance previously made which the Master Servicer has determined to be a Nonrecoverable P&I Advance in accordance with the provisions of Section 4.03;

(vii) to reimburse the Master Servicer or the Depositor for expenses incurred by or reimbursable to the Master Servicer or the Depositor, as the case may be, pursuant to Section 6.03;

(viii) to reimburse the Master Servicer, the Trust Administrator or the Trustee, as the case may be, for expenses reasonably incurred in respect of the breach or defect giving rise to the purchase obligation under Section 2.03 or Section 2.04 of this Agreement that were included in the Purchase Price of the Mortgage Loan, including any expenses arising out of the enforcement of the purchase obligation;

(ix) to pay, or to reimburse the Master Servicer for advances in respect of expenses incurred in connection with any Mortgage Loan pursuant to Section 3.16(b);

(x)	[reserved]; and

(xi) to clear and terminate the Collection Account pursuant to Section 9.01.

The Master Servicer shall keep and maintain separate accounting, on a Mortgage Loan by Mortgage Loan basis, for the purpose of justifying any withdrawal from the Collection

Account, to the extent held by or on behalf of it, pursuant to subclauses (ii), (iii), (iv), (v), (vi), (viii) and (ix) above. The Master Servicer shall provide written notification to the Trustee, the Trust Administrator and the Paying Agent, on or prior to the next succeeding Master Servicer Remittance Date, upon making any withdrawals from the Collection Account pursuant to subclause (vii) above.

(b) The Paying Agent shall, from time to time, make withdrawals from the Distribution Account, for any of the following purposes, without priority:

(i) to make distributions to Certificateholders in accordance with Section 4.01;

(ii) to pay to itself any interest income earned on funds deposited in the Distribution Account pursuant to Section 3.12(c);

(iii) to reimburse the Trust Administrator or the Trustee pursuant to Section 7.02;

(iv)	to pay any amounts in respect of taxes pursuant to 10.01(g)(iii);
(v)	to pay any Extraordinary Trust Fund Expenses;

(vi) to reimburse the Paying Agent or the Trustee for any P&I Advance made by it under Section 7.01 (if not reimbursed by the Master Servicer) to the same extent the Master Servicer would be entitled to reimbursement under Section 3.11(a); and

(vii) to clear and terminate the Distribution Account pursuant to Section 9.01.

SECTION 3.12

Investment of Funds in the Collection Account and the Distribution Account.

(a) The Master Servicer may direct any depository institution maintaining the Collection Account (for purposes of this Section 3.12, an “Investment Account”), and the Paying Agent may direct any depository institution maintaining the Distribution Account (for purposes of this Section 3.12, also an “Investment Account”), to hold the funds in such Investment Account uninvested or to invest the funds in such Investment Account in one or more Permitted Investments specified in such instruction bearing interest or sold at a discount, and maturing, unless payable on demand, (i) no later than the Business Day immediately preceding the date on which such funds are required to be withdrawn from such account pursuant to this Agreement, if a Person other than the Paying Agent is the obligor thereon, and (ii) no later than the date on which such funds are required to be withdrawn from such account pursuant to this Agreement, if the Paying Agent is the obligor thereon. All such Permitted Investments shall be held to maturity, unless payable on demand. Any investment of funds in an Investment Account shall be made in the name of the Trust Administrator (in its capacity as such) or in the name of a nominee of the Trust Administrator. The Trust Administrator shall be entitled to sole possession (except with respect to investment direction of funds held in the Collection Account and the Distribution

Account and any income and gain realized thereon) over each such investment, and any certificate or other instrument evidencing any such investment shall be delivered directly to the Trust Administrator or its agent, together with any document of transfer necessary to transfer title to such investment to the Trust Administrator or its nominee. In the event amounts on deposit in an Investment Account are at any time invested in a Permitted Investment payable on demand, the Trust Administrator shall:

(x)	consistent with any notice required to be given thereunder, demand that payment thereon be made on the last day such Permitted Investment may otherwise mature hereunder in an amount equal to the lesser of (1) all amounts then payable thereunder and (2) the amount required to be withdrawn on such date; and
(y)	demand payment of all amounts due thereunder promptly upon determination by a Responsible Officer of the Trust Administrator that such Permitted Investment would not constitute a Permitted Investment in respect of funds thereafter on deposit in the Investment Account.

(b) All income and gain realized from the investment of funds deposited in the Collection Account held by or on behalf of the Master Servicer, shall be for the benefit of the Master Servicer and shall be subject to its withdrawal in accordance with Section 3.11. The Master Servicer shall deposit in the Collection Account the amount of any loss of principal incurred in respect of any such Permitted Investment made with funds in such accounts immediately upon realization of such loss.

(c) All income and gain realized from the investment of funds deposited in the Distribution Account held by or on behalf of the Paying Agent, shall be for the benefit of the Paying Agent and shall be subject to its withdrawal at any time. The Paying Agent shall deposit in the Distribution Account the amount of any loss of principal incurred in respect of any such Permitted Investment made with funds in such accounts immediately upon realization of such loss.

(d) Except as otherwise expressly provided in this Agreement, if any default occurs in the making of a payment due under any Permitted Investment, or if a default occurs in any other performance required under any Permitted Investment, the Trustee may and, subject to Section 8.01 and Section 8.02(a)(v), upon the request of the Holders of Certificates representing more than 50% of the Voting Rights allocated to any Class of Certificates, shall take such action as may be appropriate to enforce such payment or performance, including the institution and prosecution of appropriate proceedings.

SECTION 3.13

Maintenance of the Primary Mortgage Insurance Policies; Collections Thereunder.

The Master Servicer will maintain or cause the related Sub-Servicer, if any, to maintain in full force and effect, if required under the Mortgage Loan Purchase Agreement and to the extent available, a Primary Mortgage Insurance Policy with respect to each Mortgage Loan

so insured as of the Closing Date (or, in the case of a Qualified Substitute Mortgage Loan, on the date of substitution). Such coverage will be maintained with respect to each such Mortgage Loan for so long as it is outstanding, subject to any applicable laws or until the related Loan-to-Value Ratio is reduced to less than or equal to 80% based on Mortgagor payments. The Master Servicer shall cause the premium for each Primary Mortgage Insurance Policy to be paid on a timely basis and shall pay such premium out of its own funds if it is not otherwise paid. The Master Servicer or the related Sub-Servicer, if any, will not cancel or refuse to renew any such Primary Mortgage Insurance Policy in effect on the Closing Date (or, in the case of a Qualified Substitute Mortgage Loan, on the date of substitution) that is required to be kept in force under this Agreement unless a replacement Primary Mortgage Insurance Policy for such canceled or non-renewed policy is obtained from and maintained with a Qualified Insurer.

The Master Servicer shall not take, or permit any Sub-Servicer to take, any action which would result in non-coverage under any applicable Primary Mortgage Insurance Policy of any loss which, but for the actions of the Master Servicer or Sub-Servicer, would have been covered thereunder. The Master Servicer will comply in the performance of this Agreement with all reasonable rules and requirements of each insurer under each Primary Mortgage Insurance Policy. In connection with any assumption and modification agreement or substitution of liability agreement entered into or to be entered into pursuant to Section 3.15, the Master Servicer shall promptly notify the insurer under the related Primary Mortgage Insurance Policy, if any, of such assumption in accordance with the terms of such policies and shall take all actions which may be required by such insurer as a condition to the continuation of coverage under the Primary Mortgage Insurance Policy. If any such Primary Mortgage Insurance Policy is terminated as a result of such assumption, the Master Servicer or the related Sub-Servicer shall obtain a replacement Primary Mortgage Insurance Policy as provided above.

In connection with its activities as administrator and servicer of the Mortgage Loans, the Master Servicer agrees to prepare and present, on behalf of itself, the Trustee and the Certificateholders, claims to the insurer under any Primary Mortgage Insurance Policy in a timely fashion in accordance with the terms of such policies and, in this regard, to take such action as shall be necessary to permit recovery under any Primary Mortgage Insurance Policy respecting a defaulted Mortgage Loan. Any amounts collected by the Master Servicer under any Primary Mortgage Insurance Policy shall be deposited in the Collection Account, subject to withdrawal pursuant to Section 3.11; and any amounts collected by the Master Servicer under any Primary Mortgage Insurance Policy in respect of any REO Property shall be deposited in the Collection Account, subject to withdrawal pursuant to Section 3.23. In those cases in which a Mortgage Loan is serviced by a Sub-Servicer, the Sub-Servicer, on behalf of itself, the Trustee, and the Certificateholders, will present claims to the insurer under any Primary Mortgage Insurance Policy and all collections thereunder shall be deposited initially in the Sub-Servicing Account.

SECTION 3.14

Maintenance of Hazard Insurance and Errors and Omissions and Fidelity Coverage.

(a) The Master Servicer shall cause to be maintained for each Mortgage Loan fire insurance with extended coverage on the related Mortgaged Property in an amount which is at least equal to the least of (i) the current principal balance of such Mortgage Loan, (ii) the

amount necessary to fully compensate for any damage or loss to the improvements that are a part of such property on a replacement cost basis and (iii) the maximum insurable value of the improvements which are a part of such Mortgaged Property, in each case in an amount not less than such amount as is necessary to avoid the application of any coinsurance clause contained in the related hazard insurance policy. The Master Servicer shall also cause to be maintained fire insurance with extended coverage on each REO Property in an amount which is at least equal to the lesser of (i) the maximum insurable value of the improvements which are a part of such property and (ii) the outstanding principal balance of the related Mortgage Loan at the time it became an REO Property, plus accrued interest at the Mortgage Rate and related Servicing Advances. The Master Servicer will comply in the performance of this Agreement with all reasonable rules and requirements of each insurer under any such hazard policies. Any amounts to be collected by the Master Servicer under any such policies (other than amounts to be applied to the restoration or repair of the property subject to the related Mortgage or amounts to be released to the Mortgagor in accordance with the procedures that the Master Servicer would follow in servicing loans held for its own account, subject to the terms and conditions of the related Mortgage and Mortgage Note) shall be deposited in the Collection Account, subject to withdrawal pursuant to Section 3.11, if received in respect of a Mortgage Loan, or in the REO Account, subject to withdrawal pursuant to Section 3.23, if received in respect of an REO Property. Any cost incurred by the Master Servicer in maintaining any such insurance shall not, for the purpose of calculating distributions to Certificateholders, be added to the unpaid principal balance of the related Mortgage Loan, notwithstanding that the terms of such Mortgage Loan so permit. It is understood and agreed that no earthquake or other additional insurance is to be required of any Mortgagor other than pursuant to such applicable laws and regulations as shall at any time be in force and as shall require such additional insurance. If the Mortgaged Property or REO Property is at any time in an area identified in the Federal Register by the Federal Emergency Management Agency as having special flood hazards, the Master Servicer will cause to be maintained a flood insurance policy in respect thereof. Such flood insurance shall be in an amount equal to the lesser of (i) the unpaid principal balance of the related Mortgage Loan and (ii) the maximum amount of such insurance available for the related Mortgaged Property under the national flood insurance program (assuming that the area in which such Mortgaged Property is located is participating in such program).

In the event that the Master Servicer shall obtain and maintain a blanket policy with an insurer having a General Policy Rating of A:X or better in Best’s Key Rating Guide (or such other rating that is comparable to such rating) insuring against hazard losses on all of the Mortgage Loans, it shall conclusively be deemed to have satisfied its obligations as set forth in the first two sentences of this Section 3.14, it being understood and agreed that such policy may contain a deductible clause, in which case the Master Servicer shall, in the event that there shall not have been maintained on the related Mortgaged Property or REO Property a policy complying with the first two sentences of this Section 3.14, and there shall have been one or more losses which would have been covered by such policy, deposit to the Collection Account from its own funds the amount not otherwise payable under the blanket policy because of such deductible clause. In connection with its activities as administrator and servicer of the Mortgage Loans, the Master Servicer agrees to prepare and present, on behalf of itself, the Trustee and the Certificateholders, claims under any such blanket policy in a timely fashion in accordance with the terms of such policy.

(b) The Master Servicer shall keep in force during the term of this Agreement a policy or policies of insurance covering errors and omissions for failure in the performance of the Master Servicer’s obligations under this Agreement, which policy or policies shall be in such form and amount that would meet the requirements of Fannie Mae or Freddie Mac if it were the purchaser of the Mortgage Loans, unless the Master Servicer has obtained a waiver of such requirements from Fannie Mae or Freddie Mac. The Master Servicer shall also maintain a fidelity bond in the form and amount that would meet the requirements of Fannie Mae or Freddie Mac, unless the Master Servicer has obtained a waiver of such requirements from Fannie Mae or Freddie Mac. The Master Servicer shall provide the Trustee (upon the Trustee’s reasonable request) with copies of any such insurance policies and fidelity bond. The Master Servicer shall be deemed to have complied with this provision if an Affiliate of the Master Servicer has such errors and omissions and fidelity bond coverage and, by the terms of such insurance policy or fidelity bond, the coverage afforded thereunder extends to the Master Servicer. Any such errors and omissions policy and fidelity bond shall by its terms not be cancelable without thirty days’ prior written notice to the Trustee. The Master Servicer shall also cause each Sub-Servicer to maintain a policy of insurance covering errors and omissions and a fidelity bond which would meet such requirements.

SECTION 3.15

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

The Master Servicer will, to the extent it has knowledge of any conveyance or prospective conveyance of any Mortgaged Property by any Mortgagor (whether by absolute conveyance or by contract of sale, and whether or not the Mortgagor remains or is to remain liable under the Mortgage Note and/or the Mortgage), exercise its rights to accelerate the maturity of such Mortgage Loan under the “due-on-sale” clause, if any, applicable thereto; provided, however, that the Master Servicer shall not exercise any such rights if prohibited by law from doing so or if the exercise of such rights would impair or threaten to impair any recovery under the related Primary Mortgage Insurance Policy, if any. If the Master Servicer reasonably believes it is unable under applicable law to enforce such “due-on-sale” clause, or if any of the other conditions set forth in the proviso to the preceding sentence apply, the Master Servicer will enter into an assumption and modification agreement from or with the person to whom such property has been conveyed or is proposed to be conveyed, pursuant to which such person becomes liable under the Mortgage Note and, to the extent permitted by applicable state law, the Mortgagor remains liable thereon. The Master Servicer is also authorized to enter into a substitution of liability agreement with such person, pursuant to which the original Mortgagor is released from liability and such person is substituted as the Mortgagor and becomes liable under the Mortgage Note, provided that no such substitution shall be effective unless such person satisfies the underwriting criteria of the Master Servicer. In connection with any assumption or substitution, the Master Servicer shall apply such underwriting standards and follow such practices and procedures as shall be normal and usual in its general mortgage servicing activities and as it applies to other mortgage loans owned solely by it. The Master Servicer shall not take or enter into any assumption and modification agreement, however, unless (to the extent practicable in the circumstances) it shall have received confirmation, in writing, of the continued effectiveness of any applicable Primary Mortgage Insurance Policy or hazard insurance policy, or a new policy meeting the requirements of this Section is obtained. Any fee collected by the Master Servicer in respect of an assumption or substitution of liability agreement will be retained

by the Master Servicer as additional servicing compensation. In connection with any such assumption, no material term of the Mortgage Note (including but not limited to the related Mortgage Rate and the amount of the Monthly Payment) may be amended or modified, except as otherwise required pursuant to the terms thereof. The Master Servicer shall notify the Trustee that any such substitution or assumption agreement has been completed by forwarding to the Custodian (with a copy to the Trustee) the executed original of such substitution or assumption agreement, which document 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.

Notwithstanding the foregoing paragraph or any other provision of this Agreement, the Master Servicer shall not be deemed to be in default, breach or any other violation of its obligations hereunder by reason of any assumption of a Mortgage Loan by operation of law or by the terms of the Mortgage Note or any assumption which the Master Servicer may be restricted by law from preventing, for any reason whatever. For purposes of this Section 3.15, the term “assumption” is deemed to also include a sale (of the Mortgaged Property) subject to the Mortgage that is not accompanied by an assumption or substitution of liability agreement.

SECTION 3.16

Realization Upon Defaulted Mortgage Loans.

(a) The Master Servicer shall, consistent with the servicing standard set forth in Section 3.01, foreclose upon or otherwise comparably convert the ownership of properties securing such of the Mortgage Loans as come into and continue in default and as to which no satisfactory arrangements can be made for collection of delinquent payments pursuant to Section 3.07. The Master Servicer shall be responsible for all costs and expenses incurred by it in any such proceedings; provided, however, that such costs and expenses will be recoverable as Servicing Advances by the Master Servicer as contemplated in Section 3.11 and Section 3.23. The foregoing is subject to the provision that, in any case in which Mortgaged Property shall have suffered damage from an Uninsured Cause, the Master Servicer shall not be required to expend its own funds toward the restoration of such property unless it shall determine in its discretion that such restoration will increase the proceeds of liquidation of the related Mortgage Loan after reimbursement to itself for such expenses.

(b) Notwithstanding the foregoing provisions of this Section 3.16 or any other provision of this Agreement, with respect to any Mortgage Loan as to which the Master Servicer has received actual notice of, or has actual knowledge of, the presence of any toxic or hazardous substance on the related Mortgaged Property, the Master Servicer shall not, on behalf of the Trustee, either (i) obtain title to such Mortgaged Property as a result of or in lieu of foreclosure or otherwise, or (ii) otherwise acquire possession of, or take any other action with respect to, such Mortgaged Property, if, as a result of any such action, the Trustee, the Trust Fund, the Trust Administrator, the Master Servicer or the Certificateholders would be considered to hold title to, to be a “mortgagee-in- possession” of, or to be an “owner” or “operator” of such Mortgaged Property within the meaning of the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended from time to time, or any comparable law, unless the Master Servicer has also previously determined, based on its reasonable judgment and a report prepared

by a Person who regularly conducts environmental audits using customary industry standards, that:

(1) such Mortgaged Property is in compliance with applicable environmental laws or, if not, that it would be in the best economic interest of the Trust Fund to take such actions as are necessary to bring the Mortgaged Property into compliance therewith; and

(2) there are no circumstances present at such Mortgaged Property relating to the use, management or disposal of any hazardous substances, hazardous materials, hazardous wastes, or petroleum-based materials for which investigation, testing, monitoring, containment, clean-up or remediation could be required under any federal, state or local law or regulation, or that if any such materials are present for which such action could be required, that it would be in the best economic interest of the Trust Fund to take such actions with respect to the affected Mortgaged Property.

The cost of the environmental audit report contemplated by this Section 3.23 shall be advanced by the Master Servicer, subject to the Master Servicer’s right to be reimbursed therefor from the Collection Account as provided in Section 3.11(a)(ix), such right of reimbursement being prior to the rights of Certificateholders to receive any amount in the Collection Account received in respect of the affected Mortgage Loan or other Mortgage Loans.

If the Master Servicer determines, as described above, that it is in the best economic interest of the Trust Fund to take such actions as are necessary to bring any such Mortgaged Property into compliance with applicable environmental laws, or to take such action with respect to the containment, clean-up or remediation of hazardous substances, hazardous materials, hazardous wastes or petroleum-based materials affecting any such Mortgaged Property, then the Master Servicer shall take such action as it deems to be in the best economic interest of the Trust Fund. The cost of any such compliance, containment, cleanup or remediation shall be advanced by the Master Servicer, subject to the Master Servicer’s right to be reimbursed therefor from the Collection Account as provided in Section 3.11(a)(ix), such right of reimbursement being prior to the rights of Certificateholders to receive any amount in the Collection Account received in respect of the affected Mortgage Loan or other Mortgage Loans.

(c)	[Reserved].

(d) Proceeds received in connection with any Final Recovery Determination, as well as any recovery resulting from a partial collection of Insurance Proceeds or Liquidation Proceeds, in respect of any Mortgage Loan, will be applied in the following order of priority: first, to reimburse the Master Servicer or any Sub-Servicer for any related unreimbursed Servicing Advances and P&I Advances, pursuant to Section 3.11(a)(ii) or (a)(iii)(B); second, to accrued and unpaid interest on the Mortgage Loan, to the date of the Final Recovery Determination, or to the Due Date prior to the Distribution Date on which such amounts are to be distributed if not in connection with a Final Recovery Determination; and third, as a recovery of principal of the Mortgage Loan. If the amount of the recovery so allocated to interest is less than the full amount of accrued and unpaid interest due on such Mortgage Loan, the amount of such

recovery will be allocated by the Master Servicer as follows: first, to unpaid Servicing Fees and Administration Fees; and second, to the balance of the interest then due and owing. The portion of the recovery so allocated to unpaid Servicing Fees and unpaid Administration Fees shall be reimbursed to the Master Servicer or any Sub-Servicer pursuant to Section 3.11(a)(iii)(A).

SECTION 3.17

Trustee to Cooperate; Release of Mortgage Files.

(a) Upon the payment in full of any Mortgage Loan, or the receipt by the Master Servicer of a notification that payment in full shall be escrowed in a manner customary for such purposes, the Master Servicer will immediately notify the Custodian, on behalf of the Trustee, by a certification in the form of Exhibit E (which certification shall include a statement to the effect that all amounts received or to be received in connection with such payment which are required to be deposited in the Collection Account pursuant to Section 3.10 have been or will be so deposited) of a Servicing Officer and shall request that the Custodian, on behalf of the Trustee, deliver to it the Mortgage File. Upon receipt of such certification and request, the Custodian, on behalf of the Trustee, shall promptly release the related Mortgage File to the Master Servicer, and the Master Servicer is authorized to cause the removal from the registration on the MERS® System of any such Mortgage, if applicable, 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. No expenses incurred in connection with any instrument of satisfaction or deed of reconveyance shall be chargeable to the Collection Account or the Distribution Account.

The Trustee (or a Custodian on its behalf) shall, at the written request and expense of any Certificateholder, provide a written report to such Certificateholder of all Mortgage Files released to the Master Servicer for servicing purposes.

(b) From time to time and as appropriate for the servicing or foreclosure of any Mortgage Loan, including, for this purpose, collection under any Primary Mortgage Insurance Policy or any other insurance policy relating to the Mortgage Loans, the Custodian, on behalf of the Trustee, shall, upon request of the Master Servicer and delivery to the Custodian and the Trustee of a Request for Release in the form of Exhibit E-l, release the related Mortgage File to the Master Servicer, and the Custodian, on behalf of the Trustee, shall, at the direction of the Master Servicer, execute such documents as shall be necessary to the prosecution of any such proceedings. Such Request for Release shall obligate the Master Servicer to return each and every document previously requested from the Mortgage File to the Custodian when the need therefor by the Master Servicer no longer exists, unless the Mortgage Loan has been liquidated and the Liquidation Proceeds relating to the Mortgage Loan have been deposited in the Collection Account or the Mortgage File or such document has been delivered to an attorney, or to a public trustee or other public official as required by law, for purposes of initiating or pursuing legal action or other proceedings for the foreclosure of the Mortgaged Property either judicially or non-judicially, and the Master Servicer has delivered to the Custodian, on behalf of the Trustee, a certificate of a Servicing Officer certifying as to the name and address of the Person to which such Mortgage File or such document was delivered and the purpose or purposes of such delivery. Upon receipt of a certificate of a Servicing Officer stating that such Mortgage Loan was liquidated and that all amounts received or to be received in connection with such liquidation that are required to be deposited into the Collection Account have been so

deposited, or that such Mortgage Loan has become an REO Property, a copy of the Request for Release shall be released by the Custodian, on behalf of the Trustee, to the Master Servicer.

(c) Upon written certification of a Servicing Officer, the Trustee shall execute and deliver to the Master Servicer any court pleadings, requests for trustee’s sale or other documents reasonably necessary to the foreclosure or trustee’s sale in respect of a Mortgaged Property or to any legal action brought to obtain judgment against any Mortgagor on the Mortgage Note or Mortgage or to obtain a deficiency judgment, or to enforce any other remedies or rights provided by the Mortgage Note or Mortgage or otherwise available at law or in equity. Each such certification shall include a request that such pleadings or documents be executed by the Trustee and a statement as to the reason such documents or pleadings are required and that the execution and delivery thereof by the Trustee will not invalidate or otherwise affect the lien of the Mortgage, except for the termination of such a lien upon completion of the foreclosure or trustee’s sale.

SECTION 3.18

Servicing Compensation.

As compensation for the activities of the Master Servicer hereunder, the Master Servicer shall be entitled to the Servicing Fee and the Administration Fee with respect to each Mortgage Loan payable solely from payments of interest in respect of such Mortgage Loan, subject to Section 3.24. In addition, the Master Servicer shall be entitled to recover unpaid Servicing Fees and unpaid Administration Fees out of Insurance Proceeds or Liquidation Proceeds to the extent permitted by Section 3.11(a)(iii)(A) and out of amounts derived from the operation and sale of an REO Property to the extent permitted by Section 3.23. The right to receive the Servicing Fee and the Administration Fee may not be transferred in whole or in part except in connection with the transfer of all of the Master Servicer’s responsibilities and obligations under this Agreement.

Additional servicing compensation in the form of assumption fees, late payment charges and other similar fees and charges shall be retained by the Master Servicer (subject to Section 3.24) only to the extent such fees or charges are received by the Master Servicer. The Master Servicer shall also be entitled pursuant to Section 3.11(a)(iv) to withdraw from the Collection Account, and pursuant to Section 3.23(b) to withdraw from any REO Account, as additional servicing compensation, interest or other income earned on deposits therein, subject to Section 3.12 and Section 3.24. The Master Servicer shall be required to pay all expenses incurred by it in connection with its servicing activities hereunder (including premiums due under the Primary Insurance Policies, if any, premiums for the insurance required by Section 3.14, to the extent such premiums are not paid by the related Mortgagors or by a Sub-Servicer, servicing compensation of each Sub-Servicer, and to the extent provided herein in Section 8.05, the fees and expenses of the Trustee and the Trust Administrator) and shall not be entitled to reimbursement therefor except as specifically provided herein.

SECTION 3.19

Reports to the Trust Administrator; Collection Account Statements.

Not later than fifteen days after each Distribution Date, the Master Servicer shall forward to the Trust Administrator and the Trustee, upon the request of the Trust Administrator

or the Trustee, a statement prepared by the Master Servicer setting forth the status of the Collection Account as of the close of business on the last day of the calendar month relating to such Distribution Date and showing, for the period covered by such statement, the aggregate amount of deposits into and withdrawals from the Collection Account of each category of deposit specified in Section 3.10(a) and each category of withdrawal specified in Section 3.11. Such statement may be in the form of the then current Fannie Mae Monthly Accounting Report for its Guaranteed Mortgage Pass-Through Program with appropriate additions and changes, and shall also include information as to the aggregate of the outstanding principal balances of all of the Mortgage Loans as of the last day of the calendar month immediately preceding such Distribution Date. Copies of such statement shall be provided by the Trust Administrator to the Certificates Registrar, and the Certificate Registrar shall provide the same to any Certificateholder and to any Person identified to the Certificate Registrar as a prospective transferee of a Certificate, upon the request and at the expense of the requesting party, provided such statement is delivered by the Master Servicer to the Trust Administrator and by the Trust Administrator to the Certificate Registrar.

SECTION 3.20

Statement as to Compliance.

The Master Servicer shall deliver to the Trustee, the Trust Administrator, the Depositor and the Rating Agencies on or before March 15 of each year, commencing in 2006, an Officer’s Certificate, certifying that with respect to the period ending December 31 of the prior year: (i) such Servicing Officer has reviewed the activities of such Master Servicer during the preceding calendar year or portion thereof and its performance under this Agreement, (ii) to the best of such Servicing Officer’s knowledge, based on such review, such Master Servicer has performed and fulfilled its duties, responsibilities and obligations under this Agreement in all material respects throughout such year, or, if there has been a default in the fulfillment of any such duties, responsibilities or obligations, specifying each such default known to such Servicing Officer and the nature and status thereof, (iii) nothing has come to the attention of such Servicing Officer to lead such Servicing Officer to believe that any Servicer has failed to perform any of its duties, responsibilities and obligations under its Servicing Agreement in all material respects throughout such year, or, if there has been a material default in the performance or fulfillment of any such duties, responsibilities or obligations, specifying each such default known to such Servicing Officer and the nature and status thereof. Copies of such statements shall be provided to any Certificateholder upon request, by the Trust Administrator at the Master Servicer’s expense.

SECTION 3.21

Independent Public Accountants’ Servicing Report.

The Master Servicer at its expense shall cause a nationally recognized firm of independent certified public accountants to furnish a statement to the Trustee, the Trust Administrator, the Depositor and the Rating Agencies on or before March 15 of each year, commencing in 2006 to the effect that, with respect to the most recently ended fiscal year, such firm has examined certain records and documents relating to the Master Servicer’s performance of its servicing obligations under this Agreement and pooling and servicing and trust agreements in material respects similar to this Agreement and to each other and that, on the basis of such examination conducted substantially in compliance with the audit program for mortgages serviced for Freddie Mac or the Uniform Single Attestation Program for Mortgage Bankers, such

firm is of the opinion that the Master Servicer’s activities have been conducted in compliance with this Agreement, or that such examination has disclosed no material items of noncompliance except for (i) such exceptions as such firm believes to be immaterial, (ii) such other exceptions as are set forth in such statement and (iii) such exceptions that the Uniform Single Attestation Program for Mortgage Bankers or the Audit Program for Mortgages Serviced by Freddie Mac requires it to report. Copies of such statements shall be provided to any Certificateholder upon request by the Trust Administrator at the expense of the Master Servicer. If such report discloses exceptions that are material, the Master Servicer shall advise the Trustee whether such exceptions have been or are susceptible of cure, and if susceptible of cure will take prompt action to cure.

SECTION 3.22

Access to Certain Documentation.

The Master Servicer shall provide to the Office of the Controller of the Currency, the Office of Thrift Supervision, the FDIC, and any other federal or state banking or insurance regulatory authority that may exercise authority over any Certificateholder, access to the documentation regarding the Mortgage Loans required by applicable laws and regulations. Such access shall be afforded without charge, but only upon reasonable request and during normal business hours at the offices of the Master Servicer designated by it. In addition, access to the documentation regarding the Mortgage Loans required by applicable laws and regulations will be provided to such Certificateholder, the Trustee, the Trust Administrator and to any Person identified to the Master Servicer as a prospective transferee of a Certificate, upon reasonable request during normal business hours at the offices of the Master Servicer designated by it at the expense of the Person requesting such access.

SECTION 3.23

Title, Management and Disposition of REO Property.

(a) The deed or certificate of sale of any REO Property shall be taken in the name of the Trustee, or its nominee, in trust for the benefit of the Certificateholders. The Master Servicer, on behalf of the Trust Fund, shall either sell any REO Property before the close of the third taxable year following the year the Trust Fund acquires ownership of such REO Property for purposes of Section 860G(a)(8) of the Code or request from the Internal Revenue Service, no later than 60 days before the day on which the above three-year grace period would otherwise expire, an extension of the above three-year grace period, unless the Master Servicer shall have delivered to the Trustee, the Trust Administrator and the Depositor an Opinion of Counsel, addressed to the Trustee, the Trust Administrator and the Depositor, to the effect that the holding by the Trust Fund of such REO Property subsequent to the close of the third taxable year after its acquisition will not result in the imposition on the Trust Fund of taxes on “prohibited transactions” thereof, as defined in Section 860F of the Code, or cause any Trust REMIC to fail to qualify as a REMIC under Federal law at any time that any Certificates are outstanding. The Master Servicer shall manage, conserve, protect and operate each REO Property for the Certificateholders solely for the purpose of its prompt disposition and sale in a manner which does not cause such REO Property to fail to qualify as “foreclosure property” within the meaning of Section 860G(a)(8) of the Code or result in the receipt by any Trust REMIC of any “income from non-permitted assets” within the meaning of Section 860F(a)(2)(B) of the Code, or any “net income from foreclosure property” which is subject to taxation under the REMIC Provisions.

(b) The Master Servicer shall segregate and hold all funds collected and received in connection with the operation of any REO Property separate and apart from its own funds and general assets and shall establish and maintain with respect to REO Properties an account held in trust for the Trustee for the benefit of the Certificateholders (the “REO Account”), which shall be an Eligible Account. The Master Servicer shall be permitted to allow the Collection Account to serve as the REO Account, subject to separate ledgers for each REO Property. The Master Servicer shall be entitled to retain or withdraw any interest income paid on funds deposited in the REO Account.

(c) The Master Servicer shall have full power and authority, subject only to the specific requirements and prohibitions of this Agreement, to do any and all things in connection with any REO Property as are consistent with the manner in which the Master Servicer manages and operates similar property owned by the Master Servicer or any of its Affiliates, all on such terms and for such period as the Master Servicer deems to be in the best interests of Certificateholders. In connection therewith, the Master Servicer shall deposit, or cause to be deposited in the clearing account (which account must be an Eligible Account) in which it customarily deposits payments and collections on mortgage loans in connection with its mortgage loan servicing activities on a daily basis, and in no event more than two Business Days after the Master Servicer’s receipt thereof, and shall thereafter deposit in the REO Account, in no event more than one Business Day after the deposit of such funds into the clearing account, all revenues received by it with respect to an REO Property and shall withdraw therefrom funds necessary for the proper operation, management and maintenance of such REO Property including, without limitation:

(i) all insurance premiums due and payable in respect of such REO Property;

(ii) all real estate taxes and assessments in respect of such REO Property that may result in the imposition of a lien thereon; and

(iii)

all costs and expenses necessary to maintain such REO Property.

To the extent that amounts on deposit in the REO Account with respect to an REO Property are insufficient for the purposes set forth in clauses (i) through (iii) above with respect to such REO Property, the Master Servicer shall advance from its own funds such amount as is necessary for such purposes if, but only if, the Master Servicer would make such advances if the Master Servicer owned the REO Property and if in the Master Servicer’s judgment, the payment of such amounts will be recoverable from the rental or sale of the REO Property.

Notwithstanding the foregoing, none of the Master Servicer, the Trust Administrator or the Trustee shall:

(i) authorize the Trust Fund to enter into, renew or extend any New Lease with respect to any REO Property, if the New Lease by its terms will give rise to any income that does not constitute Rents from Real Property;

(ii) authorize any amount to be received or accrued under any New Lease other than amounts that will constitute Rents from Real Property;

(iii) authorize any construction on any REO Property, other than the completion of a building or other improvement thereon, and then only if more than ten percent of the construction of such building or other improvement was completed before default on the related Mortgage Loan became imminent, all within the meaning of Section 856(e)(4)(B) of the Code; or

(iv) authorize any Person to Directly Operate any REO Property on any date more than 90 days after its date of acquisition by the Trust Fund;

unless, in any such case, the Master Servicer has obtained an Opinion of Counsel, provided to the Trust Administrator and the Trustee, to the effect that such action will not cause such REO Property to fail to qualify as “foreclosure property” within the meaning of Section 860G(a)(8) of the Code at any time that it is held by the Trust Fund, in which case the Master Servicer may take such actions as are specified in such Opinion of Counsel.

The Master Servicer may contract with any Independent Contractor for the operation and management of any REO Property, provided that:

(i) the terms and conditions of any such contract shall not be inconsistent herewith;

(ii) any such contract shall require, or shall be administered to require, that the Independent Contractor pay all costs and expenses incurred in connection with the operation and management of such REO Property, including those listed above and remit all related revenues (net of such costs and expenses) to the Master Servicer as soon as practicable, but in no event later than thirty days following the receipt thereof by such Independent Contractor;

(iii) none of the provisions of this Section 3.23(c) relating to any such contract or to actions taken through any such Independent Contractor shall be deemed to relieve the Master Servicer of any of its duties and obligations to the Trustee on behalf of the Certificateholders with respect to the operation and management of any such REO Property; and

(iv) the Master Servicer shall be obligated with respect thereto to the same extent as if it alone were performing all duties and obligations in connection with the operation and management of such REO Property.

The Master Servicer shall be entitled to enter into any agreement with any Independent Contractor performing services for it related to its duties and obligations hereunder for indemnification of the Master Servicer by such Independent Contractor, and nothing in this Agreement shall be deemed to limit or modify such indemnification. The Master Servicer shall be solely liable for all fees owed by it to any such Independent Contractor, irrespective of whether the Master Servicer’s compensation pursuant to Section 3.18 is sufficient to pay such fees.

(d) In addition to the withdrawals permitted under Section 3.23(c), the Master Servicer may from time to time make withdrawals from the REO Account for any REO Property: (i) to pay itself or any Sub-Servicer unpaid Servicing Fees of Administration Fees in respect of the related Mortgage Loan; and (ii) to reimburse itself or any Sub-Servicer for unreimbursed Servicing Advances and P&I Advances made in respect of such REO Property or the related Mortgage Loan. Any income from the related REO Property received during any calendar months prior to a Final Recovery Determination, net of any withdrawals made pursuant to Section 3.23(c) or this Section 3.23(d), shall be withdrawn by the Master Servicer from each REO Account maintained by it and remitted to the Paying Agent for deposit into the Distribution Account in accordance with Section 3.10(d)(ii) on the Master Servicer Remittance Date relating to a Final Recovery Determination with respect to such Mortgage Loan, for distribution on the related Distribution Date in accordance with Section 4.01.

(e) Subject to the time constraints set forth in Section 3.23(a), and further subject to obtaining the approval of the insurer under any related Primary Mortgage Insurance Policy (if and to the extent that such approvals are necessary to make claims under such policies in respect of the affected REO Property), each REO Disposition shall be carried out by the Master Servicer at such price and upon such terms and conditions as the Master Servicer shall deem necessary or advisable, as shall be normal and usual in its general servicing activities for similar properties.

(f) The proceeds from the REO Disposition, net of any amount required by law to be remitted to the Mortgagor under the related Mortgage Loan and net of any payment or reimbursement to the Master Servicer or any Sub-Servicer as provided above, shall be remitted to the Paying Agent for deposit in the Distribution Account in accordance with Section 3.10(d)(ii) on the Master Servicer Remittance Date in the month following the receipt thereof for distribution on the related Distribution Date in accordance with Section 4.01. Any REO Disposition shall be for cash only (unless changes in the REMIC Provisions made subsequent to the Startup Day allow a sale for other consideration).

(g) The Master Servicer shall file information returns with respect to the receipt of mortgage interest received in a trade or business, reports of foreclosures and abandonments of any Mortgaged Property and cancellation of indebtedness income with respect to any Mortgaged Property as required by Sections 6050H, 6050J and 6050P of the Code, respectively. Such reports shall be in form and substance sufficient to meet the reporting requirements imposed by such Sections 6050H, 6050J and 6050P of the Code.

SECTION 3.24

Obligations of the Master Servicer in Respect of Prepayment Interest Shortfalls.

The Master Servicer shall deliver to the Paying Agent for deposit into the Distribution Account on or before 12:00 p.m. New York time on the Master Servicer Remittance Date from its own funds (or from a Sub-Servicer’s own funds received by the Master Servicer in respect of Compensating Interest) an amount equal to the lesser of (i) the aggregate of the Prepayment Interest Shortfalls for the related Distribution Date resulting from full or partial Principal Prepayments during the related Prepayment Period and (ii) the applicable Compensating Interest Payment.

SECTION 3.25

Obligations of the Master Servicer in Respect of Monthly Payments.

In the event that a shortfall in any collection on or liability with respect to any Mortgage Loan results from or is attributable to adjustments to Stated Principal Balances that were made by the Master Servicer in a manner not consistent with the terms of the related Mortgage Note and this Agreement, the Master Servicer, upon discovery or receipt of notice thereof, immediately shall deliver to the Paying Agent for deposit in the Distribution Account from its own funds the amount of any such shortfall and shall indemnify and hold harmless the Trust Fund, the Trustee, the Trust Administrator, the Depositor and any successor master servicer in respect of any such liability. Such indemnities shall survive the termination or discharge of this Agreement. If amounts paid by the Master Servicer with respect to any Mortgage Loan pursuant to this Section 3.25 are subsequently recovered from the related Mortgagor, the Master Servicer shall be permitted to reimburse itself for such amounts paid by it pursuant to this Section 3.25 from such recoveries.

ARTICLE IV

PAYMENTS TO CERTIFICATEHOLDERS

SECTION 4.01

Distributions.

(a) (1) On each Distribution Date, the Paying Agent, in accordance with calculations and determinations made by the Trust Administrator as reflected in the statement to Certificateholders prepared by the Trust Administrator pursuant to Section 4.02, shall, first, withdraw from the Distribution Account an amount equal to the Credit Risk Manager Fee for such Distribution Date and shall pay such amount to the Credit Risk Manager and, second, withdraw from the Distribution Account an amount equal to the related Available Distribution Amount and shall distribute the following amounts, in the following order of priority, from the Available Distribution Amount or Available Distribution Amounts:

(i) in the case of the Available Distribution Amount or Available Distribution Amounts, concurrently, to the Holders of the Class A Certificates, and on the first Distribution Date, to the Holders of the Residual Certificates, the Interest Distribution Amount for each such Class for such Distribution Date, on a pro rata basis based on the entitlement of each such Class to such interest;

(ii) in the case of the remaining Available Distribution Amount, first, to the Holders of the Residual Certificates, and then to the Holders of the Class A Certificates, to the extent of the Senior Principal Distribution Amount for such Classes of Certificates, in reduction of the Certificate Principal Balances of such Classes, on a pro rata basis based on their respective Certificate Principal Balances, until the Certificate Principal Balance of each such Class has been reduced to zero;

(iii) in the case of the remaining Available Distribution Amount or Available Distribution Amounts, to the Holders of the Subordinate Certificates, the Interest Distribution Amount for each such Class for such Distribution Date, distributable to the Holders of the Subordinate Certificates in the order of priority from the Class of such

Subordinate Certificates with the lowest numerical designation to the Class of such Subordinate Certificates with the highest numerical designation;

(iv) in the case of the remaining Available Distribution Amount or Available Distribution Amounts, to the Holders of the related Subordinate Certificates, an aggregate amount equal to the Subordinate Principal Distribution Amount for such Distribution Date, allocable among the Classes of Subordinate Certificates in reduction of the Certificate Principal Balances thereof pro rata in accordance with the respective amounts payable as to each such Class pursuant to the priorities and amounts set forth in Section 4.01(b)(i); and

(v)	to the Holders of the related Residual Certificates, any remaining amounts.

Immediately prior to the distributions to the Holders of the Certificates on each Distribution Date, any adjustments to the Certificate Principal Balances of the Certificates required by this paragraph shall be made. An amount equal to the lesser of (x) the amount of Subsequent Recoveries included in the Available Funds for such Distribution Date and (y) the aggregate amount of Realized Losses, other than Excess Bankruptcy Losses, Excess Fraud Losses, Excess Special Hazard Losses and Extraordinary Losses, previously allocated to the Certificates and that remain “outstanding” as set forth below shall be applied as follows: first, to increase the Certificate Principal Balance of the Class of Certificates with the highest payment priority to which such Realized Losses were previously allocated, to the extent of any such Realized Losses previously allocated to such Class and remaining “outstanding” second, to increase the Certificate Principal Balance of the Class of Certificates with the next highest payment priority to which such Realized Losses were previously allocated, to the extent of any such Realized Losses previously allocated to such Class and remaining “outstanding” and so forth. For purposes of the foregoing, with respect to any Class of Certificates, the amount of previously allocated Realized Losses that have been offset by an increase in Certificate Principal Balance as provided above shall be deemed no longer “outstanding” but not by more than the amount of Realized Losses previously allocated to that Class of Certificates pursuant to Section 4.04. Holders of any Class of Certificates with respect to which there shall have been a Certificate Principal Balance increase pursuant to this paragraph will not be entitled to any distribution in respect of interest on the amount of such increase for any Interest Accrual Period preceding the Distribution Date on which such increase occurs. Any such increases shall be applied to the Certificate Principal Balance of each Certificate of such Class in accordance with its respective Percentage Interest.

(2) All references above to the Certificate Principal Balance of any Class of Certificates shall be to the Certificate Principal Balance of such Class prior to the allocation of Extraordinary Trust Fund Expenses and Realized Losses, in each case allocated to such Class of Certificates, on such Distribution Date pursuant to Section 4.04.

(b) (i) On each Distribution Date, the aggregate distributions of principal made on such date in respect of the Subordinate Certificates pursuant to Section 4.01(a)(1)(iv) above shall be applied among the various Classes thereof, in the order of priority from the Class of Subordinate Certificates with the lowest numerical designation to the Class of Subordinate Certificates with the highest numerical designation, in each case to the extent of remaining

available funds up to the amount allocable to such Class for such Distribution Date and in each case until the aggregate Certificate Principal Balance of each such Class is reduced to zero, in an amount with respect to each such Class equal to the sum of (X) the related Class B Percentage of the amounts described in clauses (i) through (v) of clause (a) of the definition of Subordinate Principal Distribution Amount, (Y) the portion of the amounts described in clauses (b), (c) and (e) of the definition of Subordinate Principal Distribution Amount allocable to such Class pursuant to Section 4.01(b)(ii) below and (Z) the excess, if any, of the amount required to be distributed to such Class pursuant to this Section 4.01(b)(i) for the immediately preceding Distribution Date, over the aggregate distributions of principal made in respect of such Class of Certificates on such immediately preceding Distribution Date pursuant to Section 4.01 to the extent that any such excess is not attributable to Realized Losses which were allocated to Subordinate Certificates with a lower priority pursuant to Section 4.04.

(ii) On any Distribution Date, the portion of (a) all net Liquidation Proceeds and Insurance Proceeds with respect to any Mortgage Loans that were the subject of a Final Recovery Determination in the related Prepayment Period and (b) all Principal Prepayments received in respect of the Mortgage Loans in the related Prepayment Period, allocable to principal and not included in the Senior Principal Distribution Amount, will be allocated on a pro rata basis among the following Classes of Subordinate Certificates (each, an “Eligible Class”) in proportion to the respective outstanding Certificate Principal Balances thereof: (i) the Class B-1 Certificates, (ii) the Class B-2 Certificates, if on such Distribution Date the aggregate percentage interest evidenced by the Class B-2 Certificates, the Class B-3 Certificates, the Class B-4 Certificates, the Class B-5 Certificates and the Class B-6 Certificates equals or exceeds 1.80% before giving effect to distributions on such Distribution Date, (iii) the Class B-3 Certificates, if on such Distribution Date the aggregate percentage interest evidenced by the Class B-3 Certificates, the Class B-4 Certificates, the Class B-5 Certificates and the Class B-6 Certificates equals or exceeds 1.20% before giving effect to distributions on such Distribution Date, (iv) the Class B-4 Certificates, if on such Distribution Date the aggregate percentage interest evidenced by the Class B-4 Certificates, the Class B-5 Certificates and the Class B-6 Certificates equals or exceeds 0.80% before giving effect to distributions on such Distribution Date, (v) the Class B-5 Certificates, if on such Distribution Date the aggregate percentage interest evidenced by the Class B-5 Certificates and the Class B-6 Certificates equals or exceeds 0.45% before giving effect to distributions on such Distribution Date and (vi) the Class B-6 Certificates, if on such Distribution Date the percentage interest evidenced by the Class B-6 Certificates equals or exceeds 0.20% before giving effect to distributions on such Distribution Date. If any of the foregoing Certificates is not an Eligible Class, any amounts allocable to principal and distributable pursuant to this Section 4.01(b)(ii) will be distributed among the Certificates that are Eligible Classes in the manner set forth above.

Notwithstanding the foregoing, if the application of the foregoing on any Distribution Date as provided in Section 4.01 would result in a distribution in respect of principal to any Class or Classes of Subordinate Certificates in an amount greater than the remaining Certificate Principal Balance thereof (any such Class, a “Maturing Class”) then: (a) the amount to be allocated to each Maturing Class shall be reduced to a level that, when applied as described above, would exactly reduce the Certificate Principal Balance of such Class to zero and (b) the total amount of the reduction in the amount to be allocated to the Maturing Class or Classes shall be allocated among the remaining related Eligible Classes on a pro rata basis in proportion to the

respective outstanding Certificate Principal Balances thereof prior to the allocation thereto of any of the amounts described in the preceding sentence.

(c) All distributions made with respect to each Class of Certificates on each Distribution Date shall be allocated pro rata among the outstanding Certificates in such Class based on their respective Percentage Interests. Payments in respect of each Class of Certificates on each Distribution Date will be made to the Holders of the respective Class of record on the related Record Date (except as otherwise provided in Section 4.01(e) or Section 9.01 respecting the final distribution on such Class), based on the aggregate Percentage Interest represented by their respective Certificates, and shall be made by wire transfer of immediately available funds to the account of any such Holder at a bank or other entity having appropriate facilities therefor, if such Holder shall have so notified the Certificate Registrar in writing at least five Business Days prior to the Record Date immediately prior to such Distribution Date and with respect to any Class of Certificates other than the Residual Certificates is the registered owner of Certificates having an initial aggregate Certificate Principal Balance that is in excess of the lesser of (i) $5,000,000 or (ii) two-thirds of the initial Certificate Principal Balance of such Class of Certificates, or otherwise by check mailed by first class mail to the address of such Holder 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 of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final distribution.

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

(d) The rights of the Certificateholders to receive distributions in respect of the Certificates, and all interests of the Certificateholders in such distributions, shall be as set forth in this Agreement. None of the Holders of any Class of Certificates, the Depositor, the Trustee, the Trust Administrator, the Authenticating Agent, the Paying Agent, the Certificate Registrar or the Master Servicer shall in any way be responsible or liable to the Holders of any other Class of Certificates in respect of amounts properly previously distributed on the Certificates.

(e) Except as otherwise provided in Section 9.01, whenever the Trust Administrator expects that the final distribution with respect to any Class of Certificates will be made on the next Distribution Date, the Trust Administrator shall so timely advise the Paying Agent and the Paying Agent shall, no later than five days after the latest related Determination Date, mail on such date to each Holder of such Class of Certificates a notice to the effect that:

(i) the Paying Agent expects that the final distribution with respect to such Class of Certificates will be made on such Distribution Date, but only upon presentation and surrender of such Certificates at the office of the Certificate Registrar therein specified, and

(ii) no interest shall accrue on such Certificates from and after the end of the related Interest Accrual Period.

(iii) Any funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Holder or Holders to tender their Certificates shall, on such date, be set aside and held in trust by the Paying Agent and credited to the account of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to this Section 4.01(e) shall not have been surrendered for cancellation within six months after the time specified in such notice, the Paying Agent shall mail a second notice to the remaining non-tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Paying Agent shall, directly or through an agent, mail a final notice to remaining non-tendering Certificateholders concerning surrender of their Certificates and shall continue to hold any remaining funds for the benefit of non-tendering Certificateholders. The costs and expenses of maintaining the funds in trust and of contacting such Certificateholders shall be paid out of the assets remaining in such trust fund. If within one year after the final notice any such Certificates shall not have been surrendered for cancellation, the Paying Agent shall pay to the Citigroup Global Markets Inc. all such amounts, and all rights of non-tendering Certificateholders in or to such amounts shall thereupon cease. No interest shall accrue or be payable to any Certificateholder on any amount held in trust by the Paying Agent as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with this Section 4.01(e).
