POOLING AND SERVICING AGREEMENT

THIS POOLING AND SERVICING AGREEMENT, dated May 25, 2006, is hereby executed by and among WACHOVIA MORTGAGE LOAN TRUST, LLC, as Depositor, U.S. BANK NATIONAL ASSOCIATION (“U.S. Bank”), as Master Servicer and Certificate Administrator, NATIONAL CITY MORTGAGE CO. (“National City”), as a Servicer, WELLS FARGO BANK, N.A. (“Wells Fargo”), as a Servicer, and HSBC BANK, USA, as Trustee.

W I T N E S S E T H T H A T:

In consideration of the mutual agreements herein contained, the Depositor, the Master Servicer, the Servicers, the Certificate Administrator and the Trustee agree as follows:

PRELIMINARY STATEMENT

In exchange for the Certificates, the Depositor will convey the Trust Estate to the Trustee and create the Trust.

Lower-Tier REMIC

As provided herein, the Certificate Administrator, on behalf of the Trustee, will make an election to treat the entire segregated pool of assets described in the definition of Trust Estate (including the Mortgage Loans), and subject to this Agreement, as a real estate mortgage investment conduit (a “REMIC”) for federal income tax purposes and such segregated pool of assets will be designated as the “Lower-Tier REMIC.” Component I of the Class 1-A-R Certificates will represent ownership of the sole class of “residual interests” in the Lower-Tier REMIC for purposes of the REMIC Provisions (as defined herein).

The following table irrevocably sets forth the designation, Uncertificated Pass-Through Rate and initial Uncertificated Principal Balance for each of the “regular interests” in the Lower-Tier REMIC (the “Uncertificated Lower-Tier Regular Interests”) and the designation, Pass-Through Rate and initial Class Certificate Balance of Component I of the Class 1-A-R Certificates. None of the Uncertificated Lower-Tier Regular Interests will be certificated. Solely for purposes of satisfying Treasury regulation Section 1.860G-1(a)(4)(iii), the “latest possible maturity date” for each of the Uncertificated Lower-Tier Regular Interests and Component I of the Class 1-A-R Certificates shall be the REMIC Certificate Maturity Date.

Y-2	Variable⁽¹⁾	$_________
Y-3	Variable⁽¹⁾	$_________
Y-4	Variable⁽¹⁾	$_________
Z-1	Variable⁽¹⁾	$_________
Z-2	Variable⁽¹⁾	$_________
Z-3	Variable⁽¹⁾	$_________

(1) Calculated in accordance with the definition of “Uncertificated Pass-Through Rate” herein.

(2) For each Distribution Date, interest will accrue on Component I of the Class 1-A-R Certificates at a per annum rate equal to the Net WAC for the Group 1 Mortgage Loans.

Upper-Tier REMIC

A segregated pool of assets consisting of the Uncertificated Lower-Tier Regular Interests will be designated as the “Upper-Tier REMIC” and the Certificate Administrator will make a separate REMIC election with respect thereto. Each of the Certificates (other than the Class 1-A-R Certificates) will be “regular interests” in the Upper-Tier REMIC (referred to collectively as the “Regular Certificates”) and Component II of the Class 1-A-R Certificates will represent ownership of the sole class of “residual interests” in the Upper-Tier REMIC for purposes of the REMIC Provisions. Solely for purposes of satisfying Treasury regulation Section 1.860G-1(a)(4)(iii), the “latest possible maturity date,” for each of the Regular Certificates and Component II of the Class 1-A-R Certificates shall be the REMIC Certificate Maturity Date. The Certificates and the Uncertificated Lower-Tier Regular Interests will represent the entire beneficial ownership interest in the Trust.

The following table sets forth characteristics of the Certificates, together with the minimum denominations and integral multiples in excess thereof in which the Classes of Certificates shall be issuable (except that one Certificate of each Class of Certificates may be issued in any amount in excess of the minimum denomination):

CONVEYANCE OF MORTGAGE LOANS;

ORIGINAL ISSUANCE OF CERTIFICATES

Section 2.01 Conveyance of Mortgage Loans.

(a) The Depositor, concurrently with the execution and delivery hereof, hereby sells, transfers, assigns, sets over and otherwise conveys to the Trustee on behalf of the

Trust for the benefit of the Certificateholders, without recourse, all the right, title and interest of the Depositor in and to the Mortgage Loans, including all interest and principal received on or with respect to the Mortgage Loans (other than payments of principal and interest due and payable on the Mortgage Loans on or before the Cut-Off Date), all accounts, chattel paper, deposit accounts, documents, general intangibles, goods, instruments, investment property, letter-of-credit rights, letters of credit, money, and oil, gas, and other minerals, consisting of, arising from, or relating to, any of the foregoing, and all proceeds of the foregoing. The foregoing sale, transfer, assignment and set over does not and is not intended to result in a creation of an assumption by the Trustee of any obligation of the Depositor or any other Person in connection with the Mortgage Loans or any agreement or instrument relating thereto, except as specifically set forth herein. In connection with the conveyance by the Depositor of the Mortgage Loans, the Depositor further agrees, at its own expense, on or prior to the Closing Date, to indicate on its books and records that the Mortgage Loans have been sold to the Trustee on behalf of the Trust pursuant to this Agreement, and to deliver to the Trustee the Mortgage Loan Schedule. The Mortgage Loan Schedule shall be marked as Exhibit D-1, Exhibit D-2, Exhibit D-3 and Exhibit D-4 to this Agreement and is hereby incorporated into and made a part of this Agreement.

(b) In connection with such transfer and assignment, the Depositor has delivered or caused to be delivered to the Custodian, on behalf of the Trustee, for the benefit of the Certificateholders, the following documents or instruments with respect to each Mortgage Loan so assigned:

(i) the original Mortgage Note, endorsed by manual or facsimile signature either (A) in blank or (B) in the following form: “Pay to the order of HSBC Bank USA, National Association, as Trustee, without recourse,” with all necessary intervening endorsements showing a complete chain of endorsement from the originator to the Trustee (each such endorsement being sufficient to transfer all right, title and interest of the party so endorsing in and to that Mortgage Note);

(ii) except as provided below, the original recorded Mortgage with evidence of a recording thereon, or if any such Mortgage has not been returned from the applicable recording office or has been lost, or if such public recording office retains the original recorded Mortgage, a copy of such Mortgage certified by the Depositor as being a true and correct copy of the Mortgage, if such copy is available;

(iii) subject to the provisos at the end of this paragraph, a duly executed Assignment of Mortgage to “HSBC Bank USA, National Association, as trustee for the holders of the Wachovia Mortgage Loan Trust, LLC Mortgage Pass-Through Certificates, Series 2006-A Certificates” (which may be included in a blanket assignment or assignments), together with, except as provided below, originals of all interim recorded assignments of such mortgage or copies of such interim assignments certified by the Depositor as being true and complete copies of the original recorded intervening assignments of mortgage (each such assignment, when duly and validly completed, to be in recordable form and sufficient to effect the assignment of the related Mortgage to the assignee thereof); provided that, if the related Mortgage has not been returned from the applicable public recording office, such Assignment of Mortgage may exclude the

information to be provided by the recording office; and provided, further, if the related Mortgage has been recorded in the name of Mortgage Electronic Registration Systems, Inc. (“MERS”) or its designee, no Assignment of Mortgage in favor of the Trustee will be required to be prepared or delivered and instead, the Servicer servicing such Mortgage shall take all actions as are necessary to cause the Trust or the Trustee to be shown as the owner of the related Mortgage Loan on the records of MERS for purposes of the system of recording transfers of mortgages maintained by MERS;

(iv) the originals of all assumption, modification, consolidation or extension agreements, if any, with evidence of recording thereon, if any;

(v) the original or duplicate original mortgagee title insurance policy and all riders thereto;

(vi) the original of any guarantee executed in connection with the Mortgage Note;

(vii) for each Mortgage Loan, if any, which is secured by a residential long-term lease, a copy of the lease with evidence of recording indicated thereon, or, if the lease is in the process of being recorded, a photocopy of the lease, certified by an officer of the respective prior owner of such Mortgage Loan or by the applicable title insurance company, closing/settlement/escrow agent or company or closing attorney to be a true and correct copy of the lease transmitted for recordation;

(viii) the original of any security agreement, chattel mortgage or equivalent document executed in connection with the Mortgage; and

(ix) for each Mortgage Loan secured by Co-op Shares, the originals of the following documents or instruments:

(A) The stock certificate;

(B) The stock power executed in blank;

(D) The executed recognition agreement;

(E) The executed assignment of recognition agreement, if any;

(F) The executed UCC-1 financing statement with evidence of recording thereon; and

(G) Executed UCC-3 financing statements or other appropriate UCC financing statements, evidencing a complete and unbroken line of assignments from the mortgagee to the Trustee with evidence of recording thereon (or in a form suitable for recordation).

provided, however, that on the Closing Date, with respect to item (iii), the Depositor has delivered to the Custodian a copy of such Assignment of Mortgage in blank and has caused the Servicer servicing the related Mortgage Loan to retain the completed Assignment of Mortgage for recording as described below, unless such Mortgage has been recorded in the name of MERS or its designee. In addition, if the Depositor is unable to deliver or cause the delivery of any original Mortgage Note due to the loss of such original Mortgage Note, the Depositor may deliver a Lost Note Affidavit together with a copy of such Mortgage Note, if a copy is available, and shall thereby be deemed to have satisfied the document delivery requirements of this Section 2.01(b).

If in connection with any Mortgage Loans, the Depositor cannot deliver (A) the Mortgage, (B) all interim recorded assignments, (C) all assumption, modification, consolidation or extension agreements, if any, or (D) the lender’s title policy (together with all riders thereto) satisfying the requirements of clause (ii), (iii), (iv) or (v) above, respectively, concurrently with the execution and delivery hereof because such document or documents have not been returned from the applicable public recording office in the case of clause (ii), (iii) or (iv) above, or because the title policy has not been delivered to either the Servicer servicing such Mortgage Loan or the Depositor by the applicable title insurer in the case of clause (v) above, the Depositor shall promptly deliver or cause to be delivered to the Custodian, in the case of clause (ii), (iii) or (iv) above, such Mortgage, such interim assignment or such assumption, modification, consolidation or extension agreement, as the case may be, with evidence of recording indicated thereon upon receipt thereof from the public recording office, but in no event shall any such delivery of any such documents or instruments be made later than one year following the Closing Date, unless, in the case of clause (ii), (iii) or (iv) above, there has been a continuing delay at the applicable recording office or, in the case of clause (v), there has been a continuing delay at the applicable insurer and the Depositor has delivered an Officer’s Certificate to such effect to the Custodian. The Depositor shall forward or cause to be forwarded to the Custodian (1) from time to time additional original documents evidencing an assumption or modification of a Mortgage Loan and (2) any other documents required to be delivered by the Depositor or the related Servicer to the Custodian. In the event that the original Mortgage is not delivered and in connection with the payment in full of the related Mortgage Loan the public recording office requires the presentation of a “lost instruments affidavit and indemnity” or any equivalent document, because only a copy of the Mortgage can be delivered with the instrument of satisfaction or reconveyance, the Servicer servicing such Mortgage Loan shall prepare, execute and deliver or cause to be prepared, executed and delivered, on behalf of the Trust, such a document to the public recording office.

As promptly as practicable subsequent to such transfer and assignment, and in any event, within 30 days thereafter, the related Servicer shall (except for any Mortgage which has been recorded in the name of MERS or its designee) (I) cause each Assignment of Mortgage to be in proper form for recording in the appropriate public office for real property records within 30 days of the Closing Date and (II) at the Depositor’s expense, cause to be delivered for recording in the appropriate public office for real property records the Assignments of the Mortgages in favor of the Trustee, except that, with respect to any Assignment of a Mortgage as to which the Servicer servicing such Mortgage has not received the information required to prepare such assignment in recordable form, such Servicer’s obligation to do so and to deliver the same for such recording shall be as soon as practicable after receipt of such information and

in any event within 30 days after the receipt thereof and, no recording of an Assignment of Mortgage will be required in a state if recording is not required by the Rating Agencies to obtain the initial ratings for the Certificates.

In the case of Mortgage Loans that have been prepaid in full as of the Closing Date, the Depositor, in lieu of delivering the above documents to the Custodian will cause the Servicer servicing such Mortgage Loan to deposit in the related Servicer Custodial Account the amount of such payment in full.

It is agreed and understood by the Depositor, the Trustee, National City and Wells Fargo that none of the Mortgage Loans are (a) loans subject to 12 CFR Section 226.31, 12 CFR Section 226.32 or 12 CFR Section 226.34, as amended, or (b) “high cost home,” “covered” (excluding home loans defined as “covered home loans” in the New Jersey Home Ownership Security Act of 2002 that were originated between November 26, 2003 and July 7, 2004), “high risk home” or “predatory” loans under any applicable state, federal or local law (or a similarly classified loan using different terminology under a law imposing heightened regulatory scrutiny or additional legal liability for residential mortgage loans having high interest rates, points and/or fees).

Section 2.02 Acceptance by the Custodian of the Mortgage Loans. Subject to the provisions of the following paragraph, pursuant to the Custodial Agreement, the Custodian, on behalf of the Trustee, declares that it will hold the documents referred to in Section 2.01 and the other documents delivered to it constituting the Mortgage Files, and that it will hold such other assets as are included in the Trust Estate, in trust for the exclusive use and benefit of all present and future Certificateholders. Upon execution of this Agreement, the Custodian will deliver to the Depositor and the Trustee an initial certification in the form of Exhibit O hereto, to the effect that, except as may be specified in the list of exceptions attached thereto, it has received the Mortgage File for each Mortgage Loan on the Mortgage Loan Schedule.

Within 90 days after the execution and delivery of this Agreement, the Custodian shall review the Mortgage Files in its possession and will deliver to the Depositor and the Trustee a final certification in the form of Exhibit P hereto. If, in the course of such review, the Custodian finds any document described in Section 2.01(b)(i), (ii), (iii), (v) and (ix)(A), (B), (C), (D), (F) and (G) which does not meet the requirements of Section 2.01 or is omitted from such Mortgage File, the Custodian shall promptly so notify the related Servicer and the Depositor. In performing any such review, the Custodian may conclusively rely on the purported genuineness of any such document and any signature thereon. It is understood that the scope of the Custodian’s review of the Mortgage Files is limited solely to confirming that the documents listed in Section 2.01(b)(i), (ii), (iii), (v) and (ix)(A), (B), (C), (D), (F) and (G) have been received and further confirming that any and all documents delivered pursuant to Section 2.01 appear on their face to have been executed and relate to the Mortgage Loans identified in the Mortgage Loan Schedule. The Custodian shall not have any responsibility for determining whether any document is valid and binding, whether the text of any assignment or endorsement is in proper or recordable form, whether any document has been recorded in accordance with the requirements of any applicable jurisdiction, or whether a blanket assignment is permitted in any applicable jurisdiction. The Depositor hereby covenants and agrees that it will promptly correct or cure such defect within 90 days from the date it was so notified of such defect and, if the

Depositor does not correct or cure such defect within such period, the Depositor will either (a) substitute for the related Mortgage Loan a Substitute Mortgage Loan, which substitution shall be accomplished in the manner and subject to the conditions set forth below or (b) repurchase such Mortgage Loan from the Trustee at the Repurchase Price for such Mortgage Loan; provided, however, that in no event shall such a substitution occur more than two years from the Closing Date; provided, further, that such substitution or repurchase shall occur within 90 days of when such defect was discovered if such defect will cause the Mortgage Loan not to be a “qualified mortgage” within the meaning of Section 860G(a)(3) of the Code.

With respect to each Substitute Mortgage Loan, the Depositor shall deliver to the Custodian, on behalf of the Trustee, for the benefit of the Certificateholders, the Mortgage Note, the Mortgage, the related Assignment of Mortgage (except for any Mortgage which has been recorded in the name of MERS or its designee), and such other documents and agreements as are otherwise required by Section 2.01, with the Mortgage Note endorsed and the Mortgage assigned as required by Section 2.01(b)(i). No substitution is permitted to be made in any calendar month after the Determination Date for such month. Monthly Payments due with respect to any such Substitute Mortgage Loan in the month of substitution shall not be conveyed to the Trust and shall be retained by the Depositor. For the month of substitution, distributions to Certificateholders will include the Monthly Payment due for such month on any Defective Mortgage Loan for which the Depositor has substituted a Substitute Mortgage Loan.

The related Servicer shall amend the Mortgage Loan Schedule to reflect the removal of each Mortgage Loan that has become a Defective Mortgage Loan and the substitution of the Substitute Mortgage Loan or Loans and such Servicer shall deliver the amended Mortgage Loan Schedule to the Custodian, the Master Servicer, the Certificate Administrator and the Trustee. Upon such substitution, each Substitute Mortgage Loan shall be subject to the terms of this Agreement in all respects, and the Depositor shall be deemed to have made to the Trustee with respect to such Substitute Mortgage Loan, as of the date of substitution, the representations and warranties made pursuant to Section 2.04. Upon any such repurchase or substitution and the deposit to the related Servicer Custodial Account of any required Repurchase Price or Substitution Adjustment Amount (as described in the next paragraph), as applicable, and receipt of a Request for Release, the Custodian shall release the Mortgage File relating to such Defective Mortgage Loan to the Depositor and shall execute and deliver at the Depositor’s direction such instruments of transfer or assignment prepared by the Depositor, in each case without recourse, as shall be necessary to transfer to the Depositor, or its designee, any Defective Mortgage Loan repurchased or substituted for pursuant to this Section 2.02.

For any month in which the Depositor substitutes one or more Substitute Mortgage Loans for one or more Defective Mortgage Loans, the amount (if any) by which the aggregate principal balance of all such Substitute Mortgage Loans in a Loan Group as of the date of substitution is less than the aggregate Stated Principal Balance of all such Defective Mortgage Loans in such Loan Group (the “Substitution Adjustment Amount” for such Loan Group) plus an amount equal to the aggregate of any unreimbursed Advances with respect to such Defective Mortgage Loans shall be deposited into the Collection Account by the Depositor on or before the Remittance Date for the Distribution Date in the month succeeding the calendar month during which the related Mortgage Loan is required to be repurchased or replaced hereunder.

The Custodian shall retain possession and custody of each Mortgage File in accordance with and subject to the terms and conditions set forth in the Custodial Agreement. Each Servicer shall promptly deliver to the Custodian, upon the execution or, in the case of documents requiring recording, receipt thereof, the originals of such other documents or instruments constituting the Mortgage File as come into each Servicer’s possession from time to time.

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

None of the Certificate Administrator, the Master Servicer, the Trustee or the Custodian shall be under any duty or obligation (i) to inspect, review or examine any such documents, instruments, certificates or other papers to determine that they are genuine, enforceable, or appropriate for the represented purpose or that they are other than what they purport to be on their face or (ii) to determine whether any Mortgage File should include any of the documents specified in Section 2.01(b)(iv), (vi), (vii) and (viii) and (ix)(E).

or to be taken in connection with the obligations of the Trustee contemplated herein, or which would materially impair the ability of the Trustee to perform under the terms of this Agreement.

(a) The Depositor hereby assigns to the Trustee all of its right, title and interest in the Mortgage Loan Purchase Agreement, including but not limited to the representations and warranties of the Seller set forth in Section 7 thereof. The obligations of the Seller under the Mortgage Loan Purchase Agreement to substitute or repurchase, as applicable, a Mortgage Loan as to which a representation set forth in Section 7 thereof is breached shall be the Trustee’s and the Certificateholders’ sole remedy for such breach. At the request of the [Trustee][Certificate Administrator], the Depositor shall take such actions as may be necessary to enable the [Trustee][Certificate Administrator] to enforce such representations and the obligations of the Seller with respect thereto and shall execute such further documents as the [Trustee][Certificate Administrator] may reasonably require in order to enable the [Trustee][Certificate Administrator] to carry out such enforcement.

(b) If the Depositor, the Master Servicer, a Servicer, or the Trustee discovers a breach of any of the representations and warranties set forth in the Mortgage Loan Purchase Agreement, which breach materially and adversely affects the value of the interests of Certificateholders or the Trustee in the related Mortgage Loan, the party discovering the breach shall give prompt written notice of the breach to the other parties and the Seller. Upon receipt by the Custodian or the applicable Servicer of the applicable Substitute Mortgage Loans, Repurchase Prices, or Substitution Adjustment Amounts (as such terms are defined in the Mortgage Loan Purchase Agreement) from the Seller as provided in the Mortgage Loan Purchase Agreement, the Custodian and the applicable Servicer shall notify the Trustee, the Custodian shall release to the Seller the related Mortgage File, and the Trustee shall execute and deliver all instruments of transfer or assignment furnished to it by the Seller, without recourse, representation or warranty, as are necessary to transfer to the Seller the Mortgage Loan or any property acquired with respect thereto. The related Servicer shall amend the Mortgage Loan Schedule to reflect such repurchase. The Custodian shall also amend its records to reflect such repurchase and shall promptly notify the Trustee, the Master Servicer and the Certificate Administrator of such amendment. If the Seller delivers a Substitute Mortgage Loan, the Custodian shall examine the Mortgage File for any Substitute Mortgage Loan in the manner set forth in Section 2.02(a).

(c) The Depositor makes the following representations and warranties as to the Mortgage Loans on which the Trustee is deemed to have relied in acquiring the Mortgage Loans. Such representations and warranties speak as of the Closing Date, but shall survive until the termination of this Agreement. Such representations and warranties shall not be waived by any of the parties to this Agreement:

(i) This Agreement creates a valid and continuing security interest (as defined in the Uniform Commercial Code as in force in the relevant jurisdiction) in the Mortgage

Loans in favor of the Trustee, which security interest is prior to all other liens, and is enforceable as such as against creditors of and purchasers from the Depositor.

(ii) The Mortgage Loans constitute “instruments” within the meaning of the Uniform Commercial Code as in force in the relevant jurisdiction.

(iii) The Depositor owns and has good and marketable title to the Mortgage Loans free and clear of any lien, claim or encumbrance of any Person.

(iv) The Depositor has received all consents and approvals required by the terms of the Mortgage Loans to the sale of the Mortgage Loans hereunder to the Trustee.

(v) The Depositor has caused or will have caused, within ten days, the filing of all appropriate financing statements in the proper filing office in the appropriate jurisdictions under applicable law in order to perfect the security interest in the Mortgage Loans granted to the Trustee hereunder.

(vi) Other than the security interest granted to the Trustee pursuant to this Agreement, the Depositor has not pledged, assigned, sold, granted a security interest in, or otherwise conveyed any of the Mortgage Loans. The Depositor has not authorized the filing of and is not aware of any financing statements against the Depositor that include a description of collateral covering the Mortgage Loans other than any financing statement relating to the security interest granted to the Trustee hereunder or that has been terminated. Debtor is not aware of any judgment or tax lien filings against it.

(vii) The Custodian has in its possession all original copies of the Mortgage Notes that constitute or evidence the Mortgage Loans. The Mortgage Notes that constitute or evidence the Mortgage Loans do not have any marks or notations indicating that they have been pledged, assigned or otherwise conveyed to any Person other than the Trustee. All financing statements filed or to be filed against the Depositor in favor of the Trustee in connection herewith describing the Mortgage Loans contain a statement to the following effect: “A purchase of or security interest in any collateral described in this financing statement will violate the rights of the secured party as more fully described in, and subject to the terms of, the related transaction documents.”

(d) The Depositor hereby covenants to maintain the perfection and priority of the security interest of the Trustee created by this Agreement.

Section 2.05 Intent of Parties and Protection of Title.

(a) It is the express intent of the Depositor and the Trustee that the transfer of the Mortgage Loans by the Depositor to the Trustee pursuant to Section 2.01(a) be, and be construed as, an absolute sale of the Mortgage Loans. It is, further, not the intention of such parties that such transfer be deemed the grant of a security interest in the Mortgage Loans by the Depositor to the Trustee to secure a debt or other obligation of the Depositor. However, in the event that, notwithstanding the intent of the parties, the Mortgage Loans are held to be the property of the Depositor, or if for any other reason this Agreement is held or deemed to create a security interest in the Mortgage Loans, then: (1) this Agreement shall constitute a security

agreement, and (2) the transfer of the Mortgage Loans provided for in Section 2.01(a) shall be deemed to be a grant by the Depositor to the Trustee of, and the Depositor hereby grants to the Trustee, to secure all of the Depositor’s obligations hereunder, a security interest in all of the Depositor’s right, title, and interest, whether now owned or hereafter acquired, in and to (i) the Mortgage Loans, (ii) all accounts, chattel paper, deposit accounts, documents, general intangibles, goods, instruments, investment property, letter-of-credit rights, letters of credit, money, and oil, gas, and other minerals, consisting of, arising from, or relating to, any of the foregoing; and (iii) all proceeds of the foregoing.

(b) The Depositor shall file such financing statements, and the Depositor, the Servicers, and the Trustee at the direction of the Depositor shall, to the extent consistent with this Agreement, take such other actions as may be necessary to ensure that, if this Agreement were found to create a security interest in the Mortgage Loans, such security interest would be a perfected security interest of first priority under applicable law and will be maintained as such throughout the term of the Agreement. In connection herewith, the Trustee shall have all of the rights and remedies of a secured party under the Uniform Commercial Code as in force in the relevant jurisdiction.

(c) It is the express intent of the parties hereto that the transfer of the Uncertificated Lower-Tier Regular Interests by the Depositor to the Trustee pursuant to this Agreement be, and be construed as, an absolute sale of the Uncertificated Lower-Tier Regular Interests. It is, further, not the intention of the parties that such transfer be deemed the grant of a security interest in the Uncertificated Lower-Tier Regular Interests by the Depositor to the Trustee to secure a debt or other obligation of the Depositor. However, in the event that, notwithstanding the intent of the parties, the Uncertificated Lower-Tier Regular Interests are held to be the property of the Depositor, or if for any other reason this Agreement is held or deemed to create a security interest in the Uncertificated Lower-Tier Regular Interests, then: (1) this Agreement shall constitute a security agreement, and (2) the transfer of the Uncertificated Lower-Tier Regular Interests provided for in this Agreement shall be deemed to be a grant by the Depositor to the Trustee of, and the Depositor hereby grants to the Trustee, to secure all of the Depositor’s obligations hereunder, a security interest in all of the Depositor’s right, title, and interest, whether now owned or hereafter acquired, in and to (i) the Uncertificated Lower-Tier Regular Interests, including all rights represented thereby in and to the Mortgage Loans and the proceeds thereof, (ii) all accounts, chattel paper, deposit accounts, documents, general intangibles, goods, instruments, investment property, letter-of-credit rights, letters of credit, money, and oil, gas, and other minerals, consisting of, arising from, or relating to, any of the foregoing; and (iii) all proceeds of the foregoing.

(d) The Depositor shall file such financing statements, and the Depositor, the Servicers, and the Trustee at the direction of the Depositor shall, to the extent consistent with this Agreement, take such other actions as may be necessary to ensure that, if this Agreement were found to create a security interest in the Uncertificated Lower-Tier Regular Interests, such security interest would be a perfected security interest of first priority under applicable law and will be maintained as such throughout the term of the Agreement. In connection herewith, the Trustee shall have all of the rights and remedies of a secured party under the Uniform Commercial Code as in force in the relevant jurisdiction.

Section 2.06 Designation of Interests in the REMIC. The Depositor hereby designates the Classes of Class A Certificates (other than the Class 1-A-R Certificates) and the Classes of Class B Certificates as classes of “regular interests” and Component II of the Class 1-A-R Certificates as the single class of “residual interest” in the Upper-Tier REMIC for the purposes of Code Sections 860G(a)(1) and 860G(a)(2), respectively. The Depositor hereby further designates each Uncertificated Lower-Tier Regular Interest as classes of “regular interests” and Component I of the Class 1-A-R Certificates as the single class of “residual interest” in the Lower-Tier REMIC for the purposes of Code Sections 860G(a)(1) and 860G(a)(2), respectively.

Section 2.07 Designation of Start-up Day. The Closing Date is hereby designated as the “start-up day” of each of the Upper-Tier REMIC and Lower-Tier REMIC within the meaning of Section 860G(a)(9) of the Code.

Section 2.08 REMIC Certificate Maturity Date. Solely for purposes of satisfying Section 1.860G-1(a)(4)(iii) of the Treasury Regulations, the “latest possible maturity date” of the regular interests in the Upper-Tier REMIC and Lower-Tier REMIC is November 1, 2035 (the “REMIC Certificate Maturity Date”).

Section 2.09 Execution and Delivery of Certificates. The Trustee (i) acknowledges the issuance of and hereby declares that it holds the Uncertificated Lower-Tier Regular Interests on behalf of the Upper-Tier REMIC and the Certificateholders and (ii) has executed and delivered to or upon the order of the Depositor, in exchange for the Mortgage Loans and Uncertificated Lower-Tier Regular Interests together with all other assets included in the definition of “Trust Estate,” receipt of which is hereby acknowledged, Certificates in authorized denominations which, together with the Uncertificated Lower-Tier Regular Interests, evidence ownership of the entire Trust Estate.

ARTICLE III

ADMINISTRATION AND SERVICING

OF MORTGAGE LOANS

Section 3.01 Servicers to Service Mortgage Loans. For and on behalf of the Certificateholders, National City (or any successor Servicer thereto) shall service and administer the National City Mortgage Loans, and Wells Fargo (or any successor Servicer thereto) shall service and administer the Wells Fargo Mortgage Loans, in each case in accordance with the terms of this Agreement, the Customary Servicing Procedures applicable to such Servicer, all applicable requirements of the Servicing Criteria, applicable law and the terms of the related Mortgage Notes and Mortgages. In connection with such servicing and administration, each Servicer shall have full power and authority, acting alone and/or through Subservicers as provided in Section 3.02, to do or cause to be done any and all things that it may deem necessary or desirable in connection with such servicing and administration including, but not limited to, the power and authority, subject to the terms hereof, (a) to execute and deliver, on behalf of the Certificateholders and the Trustee, customary consents or waivers and other instruments and documents, (b) to consent, with respect to the Mortgage Loans it services, to transfers of any Mortgaged Property and assumptions of the Mortgage Notes and related Mortgages (but only in the manner provided in this Agreement), (c) to collect any Insurance Proceeds and other Liquidation Proceeds relating to the Mortgage Loans it services, and (d) to effectuate foreclosure or other conversion of the ownership of the Mortgaged Property securing any Mortgage Loan it services. Each Servicer shall represent and protect the interests of the Trust in the same manner as it protects its own interests in mortgage loans in its own portfolio in any claim, proceeding or litigation regarding a Mortgage Loan and shall not make or permit any modification, waiver or amendment of any term of any Mortgage Loan, except as provided pursuant to Section 3.21. Without limiting the generality of the foregoing, each Servicer, in its own name or in the name of any Subservicer or the Depositor and the Trustee, is hereby authorized and empowered by the Depositor and the Trustee, when the Servicer or any Subservicer, as the case may be, believes it appropriate in its reasonable judgment, to execute and deliver, on behalf of the Trustee, the Depositor, the Certificateholders or any of them, any and all instruments of satisfaction or cancellation, or of partial or full release or discharge, and all other comparable instruments, with respect to the Mortgage Loans it services, and with respect to the related Mortgaged Properties held for the benefit of the Certificateholders. Each Servicer shall prepare and deliver to the Depositor and/or the Trustee such documents requiring execution and delivery by any or all of them as are necessary or appropriate to enable such Servicer to service and administer the Mortgage Loans it services to the extent that such Servicer is not permitted to execute and deliver such documents pursuant to the preceding sentence. Upon receipt of such documents, the Depositor and/or the Trustee, upon the direction of such Servicer, shall promptly execute such documents and deliver them to such Servicer.

In accordance with the standards of the preceding paragraph, each Servicer shall advance or cause to be advanced funds as necessary for the purpose of effecting the payment of taxes and assessments on the Mortgaged Properties relating to the Mortgage Loans it services, which Servicing Advances shall be reimbursable in the first instance from related collections from the Mortgagors pursuant to Section 3.09, and further as provided in Section 3.11. The costs, if any, incurred by a Servicer in effecting the timely payments of taxes and assessments on

the Mortgaged Properties and related insurance premiums shall not, for the purpose of calculating monthly distributions to the Certificateholders, be added to the Stated Principal Balances of the related Mortgage Loans, notwithstanding that the terms of such Mortgage Loans so permit. However, advances for taxes may be capitalized in accordance with a loan modification pursuant to Section 3.21.

The relationship of each Servicer (and of any successor to such Servicer as servicer under this Agreement) to the Trustee, the Master Servicer, the Certificateholders and the Certificate Administrator under this Agreement is intended by the parties to be that of an independent contractor and not that of a joint venturer, partner or agent.

Section 3.02 Subservicing and Subcontracting; Enforcement of the Obligations of Servicers.

(a) Each Servicer may arrange for the subservicing of any Mortgage Loan it services by a Subservicer pursuant to a Subservicing Agreement; provided, however, that such subservicing arrangement and the terms of the related Subservicing Agreement must provide for the servicing of such Mortgage Loan in a manner consistent with the servicing arrangements contemplated hereunder. Notwithstanding the provisions of any Subservicing Agreement, any of the provisions of this Agreement relating to agreements or arrangements between a Servicer and a Subservicer or reference to actions taken through a Subservicer or otherwise, the related Servicer shall remain obligated and liable to the Depositor, the Trustee and the Certificateholders for the servicing and administration of the Mortgage Loans it services in accordance with the provisions of this Agreement without diminution of such obligation or liability by virtue of such Subservicing Agreements or arrangements or by virtue of indemnification from the Subservicer and to the same extent and under the same terms and conditions as if such Servicer alone were servicing and administering those Mortgage Loans. All actions of each Subservicer performed pursuant to the related Subservicing Agreement shall be performed as agent of the related Servicer with the same force and effect as if performed directly by such Servicer.

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

(c) As part of its servicing activities hereunder, each Servicer, for the benefit of the Trustee and the Certificateholders, shall use its best reasonable efforts to enforce the obligations of each Subservicer engaged by such Servicer under the related Subservicing Agreement, to the extent that the non-performance of any such obligation would have a material and adverse effect on a Mortgage Loan. Such enforcement, including, without limitation, the legal prosecution of claims, termination of Subservicing 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 such Servicer, in its good faith business judgment, would require were it the owner of the related Mortgage Loans. Such 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

Loan or (ii) from a specific recovery of costs, expenses or attorneys fees against the party against whom such enforcement is directed.

(d) Any Subservicing Agreement entered into by a Servicer shall provide that it may be assumed or terminated by the Master Servicer, if the Master Servicer has assumed the duties of a Servicer, or any successor Servicer, at the Master Servicer’s or successor Servicer’s option, as applicable, without cost or obligation to the assuming or terminating party or the Trust, upon the assumption by such party of the obligations of the Servicer pursuant to Section 8.05. Each Servicer shall be solely responsible for any fees and expenses payable to any Subservicer in connection with the assumption or termination of any Subservicing Agreement.

Any Subservicing Agreement, and any other transactions or services relating to the Mortgage Loans involving a Subservicer, shall be deemed to be between the related Servicer and such Subservicer alone, and the Trustee, the Master Servicer, the Certificate Administrator and the Certificateholders shall not be deemed parties thereto and shall have no obligations, duties or liabilities to or with respect to the Subservicer or its officers, directors or employees, except as set forth in Section 3.01.

(e) A Servicer shall not permit a Subservicer to perform any servicing responsibilities hereunder with respect to the Mortgage Loans unless that Subservicer first agrees in writing with such Servicer to deliver an Assessment of Compliance and an Accountant’s Attestation in such manner and at such times that permits that Servicer to comply with Sections 12.07 and 12.08 of this Agreement. A Servicer shall not outsource one or more separate servicing functions hereunder with respect to the Mortgage Loans to any Subcontractor unless that Subcontractor first agrees in writing with such Servicer to deliver an Assessment of Compliance and an Accountant’s Attestation in such manner and at such times that permits that Servicer to comply with Sections 12.07 and 12.08 of this Agreement.

Section 3.03 Fidelity Bond; Errors and Omissions Insurance.

Each Servicer shall maintain, at its own expense, and provide evidence thereof to the Master Servicer upon request, a blanket fidelity bond and an errors and omissions insurance policy, with broad coverage on all officers, employees or other persons acting in any capacity requiring such persons to handle funds, money, documents or papers relating to the Mortgage Loans it services. These policies must insure the related Servicer against losses resulting from dishonest or fraudulent acts committed by such Servicer’s personnel, any employees of outside firms that provide data processing services for such Servicer, and temporary contract employees or student interns. Such fidelity bond shall also protect and insure such Servicer against losses in connection with the release or satisfaction of a Mortgage Loan without having obtained payment in full of the indebtedness secured thereby. No provision of this Section 3.03 requiring such fidelity bond and errors and omissions insurance shall diminish or relieve a Servicer from its duties and obligations as set forth in this Agreement. The minimum coverage under any such bond and insurance policy shall be at least equal to the corresponding amounts required by FNMA in the FNMA Servicing Guide or by FHLMC in the FHLMC Sellers’ & Servicers’ Guide, as amended or restated from time to time, or in an amount as may be permitted to the Servicer by express waiver of FNMA or FHLMC.

The Master Servicer shall maintain, at its own expense, a blanket fidelity bond and an errors and omissions insurance policy, affording coverage with respect to all directors, officers, employees and other Persons acting on the Master Servicer’s behalf, and covering errors and omissions in the performance of the Master Servicer’s obligations hereunder. The errors and omissions insurance policy and the fidelity bond shall be in such form and amount generally acceptable for entities serving as master servicers or trustees.

Section 3.04 Access to Certain Documentation.

The Master Servicer and each Servicer shall provide to the OTS and the FDIC and to comparable regulatory authorities supervising Holders of Subordinate Certificates and the examiners and supervisory agents of the OTS, the FDIC and such other authorities, access to the documentation required by applicable regulations of the OTS and the FDIC with respect to the Mortgage Loans. Such access shall be afforded without charge, but only upon reasonable and prior written request and during normal business hours at the offices designated by the Master Servicer and each Servicer. Nothing in this Section 3.04 shall limit the obligation of the Master Servicer or a Servicer to observe any applicable law, and the failure of the Master Servicer or such Servicer to provide access as provided in this Section 3.04 as a result of such obligation shall not constitute a breach of this Section 3.04.

Section 3.05 Maintenance of Primary Insurance Policy; Claims.

With respect to each Mortgage Loan which was covered by a Primary Insurance Policy on the Cut-off Date, or the date that such Mortgage Loan is transferred to the Trustee, the Servicer servicing such Mortgage Loan shall, without any cost to the Trust Estate, maintain or cause the Mortgagor to maintain in full force and effect a Primary Insurance Policy insuring that portion of the Mortgage Loan in excess of a percentage in conformity with FNMA requirements. Each Servicer shall pay or shall cause the Mortgagor to pay the premium thereon on a timely basis, at least until the Loan-to-Value Ratio of such Mortgage Loan is reduced to 80% or such other Loan-to-Value Ratio as may be required by law. If such Primary Insurance Policy is terminated, the related Servicer shall obtain from another insurer a comparable replacement policy, with a total coverage equal to the remaining coverage of such terminated Primary Insurance Policy. If the insurer shall cease to be an insurer acceptable to FNMA, such Servicer shall notify the Trustee in writing, it being understood that such Servicer shall not have any responsibility or liability for any failure to recover under the Primary Insurance Policy for such reason. If the related Servicer determines that recoveries under the Primary Insurance Policy are jeopardized by the financial condition of the insurer, such Servicer shall obtain from another insurer which meets the requirements of this Section 3.05 a replacement insurance policy. No Servicer shall take any action that would result in noncoverage under any applicable Primary Insurance Policy of any loss that, but for the actions of the related Servicer, would have been covered thereunder. In connection with any assumption or substitution agreement entered into or to be entered into pursuant to Section 3.13, the related Servicer shall promptly notify the insurer under the related Primary Insurance Policy, if any, of such assumption or substitution of liability in accordance with the terms of such Primary Insurance Policy and shall take all actions which may be required by such insurer as a condition to the continuation of coverage under such Primary Insurance Policy. If such Primary Insurance Policy is terminated as a result of such

assumption or substitution of liability, such Servicer shall obtain a replacement Primary Insurance Policy as provided above.

In connection with its activities as servicer, each Servicer agrees to prepare and present, on behalf of itself, the Trustee, and the Certificateholders, claims to the insurer under any Primary Insurance Policy in a timely fashion in accordance with the terms of such Primary Insurance Policy and, in this regard, to take such action as shall be necessary to permit recovery under any Primary Insurance Policy respecting a Defaulted Mortgage Loan. Pursuant to Section 3.08(b)(iii), any amounts collected by a Servicer under any Primary Insurance Policy shall be deposited in the related Servicer Custodial Account, subject to withdrawal pursuant to Section 3.11.

Each Servicer will comply with all provisions of applicable state and federal law relating to the cancellation of, or collection of premiums with respect to, Primary Insurance Policies, including, but not limited to, the provisions of the Homeowners Protection Act of 1998, and all regulations promulgated thereunder, as amended from time to time.

Section 3.06 Rights of the Depositor and Others in Respect of the Servicers.

The Depositor may, but is not obligated to, enforce the obligations of either Servicer hereunder and may, but is not obligated to, perform, or cause a designee to perform, any defaulted obligation of a Servicer hereunder and in connection with any such defaulted obligation to exercise the related rights of a Servicer hereunder; provided that no Servicer shall be relieved of any of its obligations hereunder by virtue of such performance by the Depositor or its designee. Neither the Trustee, the Certificate Administrator, the Master Servicer nor the Depositor shall have any responsibility or liability for any action or failure to act by a Servicer nor shall the Trustee, the Certificate Administrator or the Depositor be obligated to supervise the performance of a Servicer hereunder or otherwise.

Any Subservicing Agreement that may be entered into and any transactions or services relating to the Mortgage Loans involving a Subservicer in its capacity as such shall be deemed to be between the Subservicer and the related Servicer alone, and the Trustee, the Certificate Administrator, the Master Servicer and Certificateholders shall not be deemed parties thereto and shall have no obligations, duties or liabilities with respect to the Subservicer. Each Servicer shall be solely liable for all fees owed by it to any Subservicer, irrespective of whether such Servicer’s compensation pursuant to this Agreement is sufficient to pay such fees.

Section 3.07 [Reserved]..

Section 3.08 Collection of Mortgage Loan Payments; Servicer Custodial Accounts; Collection Account; Certificate Account; and Upper-Tier Certificate Account.

(a) Each Servicer will proceed diligently, in accordance with this Agreement, to collect all payments due under each of the Mortgage Loans it services when the same shall become due and payable. Further, each Servicer will in accordance with all applicable law, the terms of the Mortgage Loans, and Customary Servicing Procedures applicable thereto ascertain and estimate taxes, assessments, fire and hazard insurance premiums, mortgage insurance premiums and all other charges with respect to the Mortgage Loans it services that, as provided

in any Mortgage, will become due and payable to the end that the installments payable by the Mortgagors will be sufficient to pay such charges as and when they become due and payable. Consistent with the foregoing, each Servicer may in its discretion (i) waive any late payment charge or any prepayment charge or penalty interest in connection with the prepayment of a Mortgage Loan it services and (ii) extend the due dates for payments due on a Mortgage Note for a period not greater than 120 days; provided, however, that such Servicer cannot extend the maturity of any such Mortgage Loan past the date on which the final payment is due on the latest maturing Mortgage Loan as of the Cut-Off Date. In the event of any such arrangement, such Servicer shall make Periodic Advances on the related Mortgage Loan in accordance with the provisions of Section 3.20 during the scheduled period in accordance with the amortization schedule of such Mortgage Loan without modification thereof by reason of such arrangements. No Servicer shall be required to institute or join in litigation with respect to collection of any payment (whether under a Mortgage, Mortgage Note or otherwise or against any public or governmental authority with respect to a taking or condemnation) if it reasonably believes that enforcing the provision of the Mortgage or other instrument pursuant to which such payment is required is prohibited by applicable law.

(b) Each Servicer shall establish and maintain a Servicer Custodial Account. Each Servicer shall deposit or cause to be deposited into the related Servicer Custodial Account, all on a daily basis within one Business Day of receipt, except as otherwise specifically provided herein, the following payments and collections remitted by the related Subservicers or received by such Servicer in respect of the Mortgage Loans it services subsequent to the Cut-Off Date (other than in respect of principal and interest due on the Mortgage Loans on or before the Cut-Off Date) and the following amounts required to be deposited hereunder with respect to the Mortgage Loans it services:

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

(ii) all payments on account of interest on the Mortgage Loans, net of the Servicing Fee;

(iii) (A) all Insurance Proceeds and Liquidation Proceeds, other than Insurance Proceeds to be (1) applied to the restoration or repair of the Mortgaged Property, (2) released to the Mortgagor in accordance with Customary Servicing Procedures, the terms of the Mortgage Loan, or applicable law or (3) required to be deposited to an Escrow Account pursuant to Section 3.09(a) and (B) any Insurance Proceeds released from an Escrow Account pursuant to Section 3.09(b)(iv);

(iv) any amount required to be deposited by such Servicer pursuant to Section 3.08(d) in connection with any losses on Permitted Investments with respect to the related Servicer Custodial Account;

(v) any amounts required to be deposited by such Servicer pursuant to Section 3.14;

(vi) all Repurchase Prices, all Substitution Adjustment Amounts and all Subsequent Recoveries received by such Servicer;

(vii) Periodic Advances made by such Servicer pursuant to Section 3.20 and any payments of Compensating Interest; and

(viii) any other amounts required to be deposited hereunder.

The foregoing requirements for deposits to a Servicer Custodial Account by the related Servicer shall be exclusive, it being understood and agreed that, without limiting the generality of the foregoing, payments in the nature of prepayment penalties, late payment charges or assumption fees, if collected, need not be deposited by such Servicer. If a Servicer shall deposit in the related Servicer Custodial Account any amount not required to be deposited, it may at any time withdraw or direct the institution maintaining such Servicer Custodial Account to withdraw such amount from such Servicer Custodial Account, any provision herein to the contrary notwithstanding. A Servicer Custodial Account may contain funds that belong to one or more trust funds created for mortgage pass-through certificates of other series and may contain other funds respecting payments on mortgage loans belonging to such Servicer or serviced by such Servicer on behalf of others; provided that such commingling of funds shall not be permitted at any time during which Fitch’s senior long-term unsecured debt rating of such Servicer is below “A.” Notwithstanding such commingling of funds, each Servicer shall keep records that accurately reflect the funds on deposit in the related Servicer Custodial Account that have been identified by it as being attributable to the Mortgage Loans it services. Each Servicer shall maintain adequate records with respect to all withdrawals made pursuant to this Section 3.08. All funds required to be deposited in a Servicer Custodial Account shall be held in trust for the Certificateholders until withdrawn in accordance with Section 3.11.

(d) Each institution at which a Servicer Custodial Account is maintained shall invest the funds therein as directed in writing by the related Servicer in Permitted Investments, which shall mature not later than the Business Day next preceding the related Remittance Date (except that if such Permitted Investment is an obligation of the institution that maintains such account, then such Permitted Investment shall mature not later than such Remittance Date), and shall not be sold or disposed of prior to its maturity. All such Permitted Investments shall be made in the name of the Trustee, for the benefit of the Certificateholders.

Section 3.09 Collection of Taxes, Assessments and Similar Items; Escrow Accounts.

(a) To the extent required by the related Mortgage Note and not violative of current law, each Servicer shall segregate and hold all funds collected and received pursuant to each Mortgage Loan which constitute Escrow Payments in trust separate and apart from any of its own funds and general assets and for such purpose shall establish and maintain one or more escrow accounts (collectively, the “Escrow Accounts”), in each case titled “[Insert name of Servicer], in trust for registered holders of Wachovia Mortgage Loan Trust, LLC Mortgage Pass-Through Certificates, Series 2006-A and various Mortgagors.” Each Escrow Account shall be established with a commercial bank, a savings bank or a savings and loan association that meets the guidelines set forth by FNMA or FHLMC as an eligible institution for escrow accounts and which is a member of the Automated Clearing House. In any case, each Escrow Account shall be insured by the FDIC to the fullest extent permitted by law. Each Servicer shall deposit in the appropriate Escrow Account on a daily basis, and retain therein: (i) all Escrow Payments collected on account of the Mortgage Loans, (ii) all amounts representing proceeds of any hazard insurance policy which are to be applied to the restoration or repair of any related Mortgaged Property and (iii) all amounts representing proceeds of any Primary Insurance Policy. Nothing herein shall require a Servicer to compel a Mortgagor to establish an Escrow Account in violation of applicable law or the terms of the related Mortgage Loan.

(b) Withdrawals of amounts so collected from the Escrow Accounts may be made by a Servicer only (i) to effect timely payment of taxes, assessments, mortgage insurance premiums, fire and hazard insurance premiums, condominium or PUD association dues, or comparable items constituting Escrow Payments for the related Mortgage, (ii) to reimburse the Servicer out of related Escrow Payments made with respect to a Mortgage Loan for any Servicing Advance made by the Servicer pursuant to Section 3.09(c) with respect to such Mortgage Loan, (iii) to refund to any Mortgagor any sums determined to be overages, (iv) for transfer to a Servicer Custodial Account upon default of a Mortgagor or in accordance with the terms of the related Mortgage Loan and if permitted by applicable law, (v) for application to restore or repair the Mortgaged Property, (vi) to pay to the Mortgagor, to the extent required by law or the terms of the Mortgage Loan, any interest paid on the funds deposited in the applicable Escrow Account, (vii) to pay to itself any interest earned on funds deposited in the applicable Escrow Accounts (and not required to be paid to the Mortgagor), (viii) to the extent permitted under the terms of the related Mortgage Note and applicable law, to pay late fees with respect to any Monthly Payment which is received after the applicable grace period, (ix) to withdraw suspense payments that are deposited into an Escrow Account, (x) to withdraw any amounts inadvertently deposited in and Escrow Account or (xi) to clear and terminate any Escrow Account upon the termination of this Agreement in accordance with Section 10.01. Any Escrow Account shall not be a part of the Trust Estate.

(c) With respect to each Mortgage Loan, each Servicer shall maintain accurate records reflecting the status of taxes, assessments and other charges which are or may become a lien upon the Mortgaged Property and the status of Primary Insurance Policy

premiums and fire and hazard insurance coverage. Each Servicer shall obtain, from time to time, all bills for the payment of such charges (including renewal premiums) and shall effect payment thereof prior to the applicable penalty or termination date and at a time appropriate for securing maximum discounts allowable, employing for such purpose deposits of the Mortgagor in the Escrow Account, if any, which shall have been estimated and accumulated by such Servicer in amounts sufficient for such purposes, as allowed under the terms of the Mortgage Loan. To the extent that a Mortgage Loan does not provide for Escrow Payments, such Servicer shall determine whether any such payments are made by the Mortgagor. Each Servicer assumes full responsibility for the timely payment of all such bills and shall effect timely payments of all such bills irrespective of each Mortgagor’s faithful performance in the payment of same or the making of the Escrow Payments. Each Servicer shall advance any such payments that are not timely paid, but each Servicer shall be required so to advance only to the extent that such Servicing Advances, in the good faith judgment of the related Servicer, will be recoverable by such Servicer out of Insurance Proceeds, Liquidation Proceeds or otherwise.

Section 3.10 Access to Certain Documentation and Information Regarding the Mortgage Loans.

Each Servicer shall afford the Master Servicer and the Trustee reasonable access to all records and documentation in its possession regarding the Mortgage Loans it services and all accounts, insurance information and other matters relating to this Agreement, such access being afforded without charge, but only upon reasonable request and during normal business hours at the office designated by each Servicer.

Upon reasonable advance notice in writing, each Servicer will provide to each Certificateholder which is a savings and loan association, bank or insurance company certain reports and reasonable access to information and documentation regarding the Mortgage Loans it services sufficient to permit such Certificateholder to comply with applicable regulations of the OTS or other regulatory authorities with respect to investment in the Certificates; provided that each Servicer shall be entitled to be reimbursed by each such Certificateholder for actual expenses incurred by such Servicer in providing such reports and access.

Section 3.11 Permitted Withdrawals from the Servicer Custodial Accounts, Collection Account, Certificate Account and Upper-Tier Certificate Account.

(a) Each Servicer may from time to time make withdrawals from the related Servicer Custodial Account, for the following purposes:

(i) to pay to such Servicer (to the extent not previously retained), the servicing compensation to which it is entitled pursuant to Section 3.17, and to pay to such Servicer, as additional servicing compensation, earnings on or investment income with respect to funds in or credited to such Servicer Custodial Account;

(ii) to reimburse such Servicer for unreimbursed Advances made by it, such right of reimbursement pursuant to this clause (ii) being limited to amounts received on the Mortgage Loan(s) in respect of which any such Advance was made;

(iii) to reimburse such Servicer for any Nonrecoverable Advance previously made or any Advances capitalized in accordance with Section 3.21(c);

(iv) to reimburse such Servicer for Insured Expenses from the related Insurance Proceeds;

(v) to pay to the purchaser, with respect to each Mortgage Loan or REO Property that has been purchased pursuant to Section 2.02 or 2.04, all amounts received thereon after the date of such purchase;

(vi) [Reserved];

(vii) to reimburse such Servicer or the Depositor for expenses incurred by any of them and reimbursable pursuant to Section 7.03;

(viii) to withdraw any amount deposited in such Servicer Custodial Account and not required to be deposited therein;

(ix) to remit to the Master Servicer on each Remittance Date (i) all amounts credited to such Servicer Custodial Account as of the close of business on the related Determination Date, net of charges against or withdrawals from such Servicer Custodial Account pursuant to this Section 3.11(a), and excluding any Principal Prepayments received after the end of the preceding calendar month, plus (ii) to the extent not already deposited in such Servicer Custodial Account, all Compensating Interest and Periodic Advances, if any, for such Distribution Date which the Servicer is obligated to remit pursuant to Sections 3.17 and 3.20, respectively, minus (iii) any amounts attributable to Monthly Payments in respect of a Due Date or Due Dates subsequent to the related Due Date for such Remittance Date; and

(x) to clear and terminate such Servicer Custodial Account upon termination of this Agreement pursuant to Section 10.01.

Each Servicer shall keep and maintain separate accounting records, on a Mortgage Loan by Mortgage Loan basis, for the purpose of justifying any withdrawal from the related Servicer Custodial Account pursuant to clauses (i), (ii), (iv) and (v). Prior to making any withdrawal from the Servicer Custodial Account pursuant to clause (iii), each Servicer shall deliver to the Master Servicer an Officer’s Certificate of a Servicing Officer indicating the amount of any previous Advance determined by such Servicer to be a Nonrecoverable Advance and identifying the related Mortgage Loan(s) and their respective portions of such Nonrecoverable Advance.

With respect to any remittance received by the Master Servicer after the Remittance Date on which such remittance was due, the applicable Servicer shall pay to the Master Servicer interest on such late payment at an annual rate equal to the prime rate, adjusted as of the date of each change, plus two (2) percentage points, but in no event greater than the maximum amount permitted by applicable law. Such interest shall be deposited in the related Servicer Custodial Account by the applicable Servicer for remittance to the Master Servicer on the date such late payment is made and shall cover the period commencing with the day

following such Remittance Date and ending with the day on which such payment is made, both inclusive. The payment by a Servicer of any such interest shall not be deemed an extension of time for payment or a waiver of any Event of Default by the Master Servicer or the Certificate Administrator.

(b) The Master Servicer may from time to time make withdrawals from the Collection Account for the following purposes:

(i) to reimburse the Master Servicer for unreimbursed Advances made by it, such right of reimbursement pursuant to this clause (i) being limited to amounts received on the Mortgage Loan(s) in respect of which any such Advance was made;

(ii) to reimburse the Master Servicer for any Nonrecoverable Advance previously made or any Advances capitalized in accordance with Section 3.21(c);

(iii) to reimburse the Master Servicer for Insured Expenses from the related Insurance Proceeds;

(iv) on each Distribution Date, to pay to the Master Servicer the Master Servicing Fee with respect to the Mortgage Loans in each Loan Group due on such Distribution Date, from the Pool Distribution Amount, and to pay to the Master Servicer as additional compensation earnings on or investment income with respect to funds in the Collection Account;

(v) to reimburse the Trustee, the Master Servicer and the Certificate Administrator for, or to pay expenses incurred by either such party which are reimbursable or payable pursuant to Section 3.01, 7.03, 7.05, 8.01, 9.07 or 9.11 of this Agreement;

(vi) to withdraw and return to the Master Servicer any amount deposited in the Collection Account and not required to be deposited therein;

(vii) to remit to the Certificate Administrator on the Business Day preceding each Distribution Date all amounts credited to the Collection Account as of such remittance, net of charges against or withdrawals from the Collection Account pursuant to this Section 3.11(b); and

(viii) to clear and terminate the Collection Account upon termination of the Agreement pursuant to Section 10.01.

The Master Servicer shall keep and maintain a separate accounting, on a Mortgage Loan by Mortgage Loan basis, and shall provide a copy to the Certificate Administrator, for the purpose of accounting for any reimbursement from the Collection Account pursuant to clauses (i) through (iii).

(c) The Certificate Administrator shall withdraw funds from the Certificate Account for (i) distributions to Certificateholders in the manner specified in this Agreement, (ii) to withdraw and return to the Certificate Administrator any amount deposited in the Certificate

Account and not required to be deposited therein; and (ii) to clear and terminate the Certificate Account upon termination of the Agreement pursuant to Section 10.01.

(d) Notwithstanding anything herein to the contrary, the Regular Certificates and the Class 1-A-R Certificates shall not receive distributions directly from the Certificate Account. On each Distribution Date, funds on deposit in the Upper-Tier Certificate Account shall be used to make payments on the Regular Certificates and the Class 1-A-R Certificates as provided in Sections 5.01 and 5.02. The Upper-Tier Certificate Account shall be cleared and terminated upon termination of this Agreement pursuant to Section 10.01.

Section 3.12 Maintenance of Hazard Insurance.

Each Servicer shall cause to be maintained for each Mortgage Loan it services, fire and hazard insurance with extended coverage customary in the area where the Mortgaged Property is located in an amount which is at least equal to the lesser of (a) the full insurable value of the Mortgaged Property or (b) the greater of (i) the outstanding principal balance owing on the Mortgage Loan and (ii) an amount such that the proceeds of such insurance shall be sufficient to avoid the application to the Mortgagor or loss payee of any coinsurance clause under the policy. If the Mortgaged Property is in an area identified in the Federal Register by the Federal Emergency Management Agency as having special flood hazards (and such flood insurance has been made available) the Servicer servicing the related Mortgage Loan will cause to be maintained a flood insurance policy meeting the requirements of the current guidelines of the Federal Insurance Administration and the requirements of FNMA or FHLMC. Each Servicer shall also maintain on REO Property, fire and hazard insurance with extended coverage in an amount which is at least equal to the maximum insurable value of the improvements which are a part of such property, liability insurance and, to the extent required, flood insurance in an amount required above. Any amounts collected by a Servicer under any such policies (other than amounts to be deposited in an Escrow Account and applied to the restoration or repair of the property subject to the related Mortgage or property acquired in liquidation of the Mortgage Loan, or to be released to the Mortgagor in accordance with the terms of the Mortgage Loan, applicable law, or applicable Customary Servicing Procedures) shall be deposited in the related Servicer Custodial Account, subject to withdrawal pursuant to Section 3.11(a). It is understood and agreed that no earthquake or other additional insurance need be required by a Servicer of any Mortgagor or maintained on REO Property, other than pursuant to such applicable laws and regulations as shall at any time be in force and as shall require such additional insurance. All policies required hereunder shall be endorsed with standard mortgagee clauses with loss payable to the related Servicer, and shall provide for at least 30 days prior written notice of any cancellation, reduction in amount or material change in coverage to such Servicer.

The hazard insurance policies for each Mortgage Loan secured by a unit in a condominium development or planned unit development shall be maintained with respect to such Mortgage Loan and the related development in a manner which is consistent with FNMA requirements.

Notwithstanding the foregoing, each Servicer may maintain a blanket policy insuring against hazard losses on all of the Mortgaged Properties relating to the Mortgage Loans in lieu of maintaining the required hazard insurance policies for each Mortgage Loan and may

maintain a blanket policy insuring against special flood hazards in lieu of maintaining any required flood insurance. Any such blanket policies shall (A) be consistent with prudent industry standards, (B) name the related Servicer as loss payee, (C) provide coverage in an amount equal to the aggregate unpaid principal balance on the related Mortgage Loans without co-insurance, and (D) otherwise comply with the requirements of this Section 3.12. Any such blanket policy may contain a deductible clause; provided that if any Mortgaged Property is not covered by a separate policy otherwise complying with this Section 3.12 and a loss occurs with respect to such Mortgaged Property which loss would have been covered by such a policy, the related Servicer shall deposit in the related Servicer Custodial Account the difference, if any, between the amount that would have been payable under a separate policy complying with this Section 3.12 and the amount paid under such blanket policy.

Section 3.13 Enforcement of Due-On-Sale Clauses; Assumption Agreements. Each Servicer shall, 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 no Servicer shall exercise any such rights if prohibited by law from doing so.

Section 3.14 Realization Upon Defaulted Mortgage Loans; REO Property.

(a) Each Servicer shall use reasonable efforts to foreclose upon or otherwise comparably convert the ownership of Mortgaged Properties securing such of the Mortgage Loans (but shall not sell or convey such Mortgage Loan, except as required pursuant to Section 2.02, 2.04 or 10.01 of this Agreement) as come into and continue in default and as to which no satisfactory arrangements can be made for collection of delinquent payments. In connection with such foreclosure or other conversion, each Servicer shall follow the Customary Servicing Procedures applicable to it and shall meet the requirements of the insurer under any Required Insurance Policy; provided, however, that a Servicer may enter into a special servicing agreement with an unaffiliated Holder of 100% Percentage Interest of a Class of Class B Certificates or a holder of a class of securities representing interests in the Class B Certificates alone or together with other subordinated mortgage pass-through certificates, but the applicable Servicer will be required to continue otherwise to service the Mortgage Loans in accordance with the provisions of this Agreement. Such agreement shall be subject to each Rating Agency’s acknowledgment that the ratings of the Certificates in effect immediately prior to the entering into such agreement would not be qualified, downgraded or withdrawn and the Certificates would not be placed on credit review status (except for possible upgrading) as a result of such agreement. Any such agreement may contain provisions whereby such holder may instruct the related Servicer to commence or delay foreclosure proceedings with respect to delinquent Mortgage Loans and will contain provisions for the deposit of cash by the holder that would be available for distribution to Certificateholders if Liquidation Proceeds are less than they otherwise may have been had such Servicer acted in accordance with its normal procedures. Notwithstanding the foregoing, no Servicer shall be required to expend its own funds in connection with any foreclosure or towards the restoration of any Mortgaged Property unless it shall determine (i) that such restoration and/or foreclosure will increase the proceeds of liquidation of the Mortgage Loan after reimbursement to itself of such expenses and (ii) that such

expenses will be recoverable to it through proceeds of the liquidation of the Mortgage Loan (respecting which it shall have priority for purposes of withdrawals from the related Servicer Custodial Account). Any such expenditures shall constitute Servicing Advances for purposes of this Agreement.

The decision of a Servicer to foreclose on a Defaulted Mortgage Loan shall be subject to a determination by such Servicer that the proceeds of such foreclosure would exceed the costs and expenses of bringing such a proceeding.

With respect to any REO Property, the deed or certificate of sale shall be taken in the name of the Trustee for the benefit of the Certificateholders, or its nominee, on behalf of the Certificateholders. The Trustee’s name shall be placed on the title to such REO Property solely as the Trustee hereunder and not in its individual capacity. The Servicer servicing the related Mortgage Loan shall ensure that the title to such REO Property references this Agreement and the Trustee’s capacity hereunder. Pursuant to its efforts to sell such REO Property, such Servicer shall either itself or through an agent selected by the Servicer manage, conserve, protect and operate such REO Property in the same manner that it manages, conserves, protects and operates other foreclosed property for its own account and in the same manner that similar property in the same locality as the REO Property is managed. Incident to its conservation and protection of the interests of the Certificateholders, such Servicer may rent the same, or any part thereof, as such Servicer deems to be in the best interest of the Certificateholders for the period prior to the sale of such REO Property. Each Servicer shall prepare for and deliver to the Certificate Administrator and the Trustee a statement with respect to each REO Property that has been rented, if any, showing the aggregate rental income received and all expenses incurred in connection with the management and maintenance of such REO Property at such times as is necessary to enable the Certificate Administrator to comply with the reporting requirements of the REMIC Provisions; provided, however, that no Servicer shall have a duty to rent any REO Property on behalf of the Trust. The net monthly rental income, if any, from such REO Property shall be deposited in the related Servicer Custodial Account no later than the close of business on each Determination Date. Each Servicer shall perform, with respect to the Mortgage Loans, the tax reporting and withholding required by Sections 1445 and 6050J of the Code with respect to foreclosures and abandonments, the tax reporting required by Section 6050H of the Code with respect to the receipt of mortgage interest from individuals and, if required by Section 6050P of the Code, with respect to the cancellation of indebtedness by certain financial entities, by preparing such tax and information returns as may be required, in the form required. Each Servicer shall deliver copies of such reports to the Certificate Administrator and the Trustee.

The Trustee shall furnish each Servicer with any powers of attorney and other documents in form as provided to it necessary or appropriate to enable such Servicer to service and administer the related Mortgage Loans and REO Property.

The Trustee shall execute and deliver to the related Servicer any court pleadings, requests for trustee’s sale or other documents necessary or desirable in connection with (i) the foreclosure or trustee’s sale with respect to a Mortgaged Property; (ii) any legal action brought to obtain judgment against any Mortgagor on the Mortgage Note or other security instrument; (iii) obtaining a deficiency judgment against the Mortgagor; or (iv) enforcing any other rights or

remedies provided by the Mortgage Note or other security instrument or otherwise available at law or equity.

The income earned from the management of any REO Properties, net of reimbursement to a Servicer for expenses incurred (including any property or other taxes) in connection with such management and net of unreimbursed Servicing Fees, Periodic Advances and Servicing Advances applicable to such Servicer, shall be applied to the payment of principal of and interest on the related Defaulted Mortgage Loans (solely for the purposes of allocating principal and interest, interest shall be treated as accruing as though such Mortgage Loans were still current) and all such income shall be deemed, for all purposes in this Agreement, to be payments on account of principal and interest on the related Mortgage Notes and shall be deposited into the related Servicer Custodial Account. To the extent the net income received during any calendar month is in excess of the amount attributable to amortizing principal and accrued interest at the related Mortgage Interest Rate on the related Mortgage Loan for such calendar month, such excess shall be considered to be a partial prepayment of principal of the related Mortgage Loan.

The proceeds from any liquidation of a Mortgage Loan, as well as any income from an REO Property, will be applied in the following order of priority: first, to reimburse the Servicer servicing such Mortgage Loan for any related unreimbursed Servicing Advances and Servicing Fees; second, to reimburse such Servicer for any unreimbursed Periodic Advances and to reimburse the related Servicer Custodial Account for any Nonrecoverable Advances (or portions thereof) that were previously withdrawn by the Servicer pursuant to Section 3.11(a)(ii) that related to such Mortgage Loan; third, to reimburse the Master Servicer, the Certificate Administrator and the Trustee for any amounts incurred by them in connection with such Mortgage Loan; fourth, to accrued and unpaid interest (to the extent no Periodic Advance has been made for such amount or any such Periodic Advance has been reimbursed) on the Mortgage Loan or related REO Property, at the Mortgage Interest Rate to the Due Date occurring in the month in which such amounts are required to be distributed; and fifth, as a recovery of principal of the Mortgage Loan. Excess Proceeds, if any, from the liquidation of a Liquidated Mortgage Loan will be retained by the Servicer as additional servicing compensation pursuant to Section 3.17.

(b) When a Mortgage Loan becomes a Defaulted Mortgage Loan, the related Servicer shall promptly notify the Certificate Administrator of such occurrence.

Section 3.15 Custodian to Cooperate; Release of Mortgage Files. Upon the payment in full of any Mortgage Loan, or the receipt by the Servicer servicing such Mortgage Loan of a notification that payment in full will be escrowed in a manner customary for such purposes, such Servicer will (and if the Servicer does not, the Master Servicer may) immediately notify the Custodian by delivering, or causing to be delivered, two copies (one of which will be returned to such Servicer with the Mortgage File) of a Request for Release (which may be delivered in an electronic format acceptable to the Custodian and such Servicer). Upon receipt of such request, the Custodian shall within seven Business Days release the related Mortgage File to or at the direction of such Servicer. The Trustee shall at such Servicer’s direction execute and deliver to such Servicer the request for reconveyance, deed of reconveyance or release or satisfaction of mortgage or such instrument releasing the lien of the Mortgage, in each case

provided by such Servicer, together with the Mortgage Note with written evidence of cancellation thereon. If the Mortgage has been recorded in the name of MERS or its designee, such Servicer shall take all necessary action to reflect the release of the Mortgage on the records of MERS. To the extent permitted by the terms of the Mortgage Loan and applicable law, expenses incurred in connection with any instrument of satisfaction or deed of reconveyance shall be chargeable to the related Mortgagor. From time to time and as shall be appropriate for the servicing or foreclosure of any Mortgage Loan, including for such purpose collection under any policy of flood insurance, any fidelity bond or errors or omissions policy, or for the purposes of effecting a partial release of any Mortgaged Property from the lien of the Mortgage or the making of any corrections to the Mortgage Note or the Mortgage or any of the other documents included in the Mortgage File, the Custodian shall, upon delivery to the Custodian of a Request for Release signed by a Servicing Officer, release the Mortgage File within seven Business Days to the Servicer servicing such Mortgage Loan. The Servicer shall cause the Mortgage File so released to be returned to the Custodian when the need therefor by the Servicer no longer exists, unless the Mortgage Loan is liquidated and the proceeds thereof are deposited in the related Servicer Custodial Account, in which case such Servicer shall deliver to the Custodian a Request for Release, signed by a Servicing Officer.

The Trustee shall execute and deliver to each Servicer any powers of attorney and other documents prepared by such Servicer that are reasonably necessary or appropriate to enable such Servicer to carry out its servicing and administrative duties under this Agreement, upon the request of such Servicer. In addition, upon prepayment in full of any Mortgage Loan or the receipt of notice that funds for such purpose have been placed in escrow, each Servicer is authorized to give, as attorney-in-fact for the Trustee and the mortgagee under the Mortgage, an instrument of satisfaction (or Assignment of Mortgage without recourse) regarding the Mortgaged Property relating to such Mortgage Loan, which instrument of satisfaction or Assignment of Mortgage, as the case may be, shall be delivered to the Person entitled thereto against receipt of the prepayment in full. If the Mortgage is registered in the name of MERS or its designee, such Servicer shall take all necessary action to reflect the release on the records of MERS. Such Servicer may deliver or cause to be delivered to the Trustee, for signature, as appropriate, any court pleadings, requests for trustee’s sale or other documents necessary to effectuate any foreclosure or any legal action brought to obtain judgment against the Mortgagor on the Mortgage Note or the Mortgage or to obtain a deficiency judgment or to enforce any other remedies or rights provided by the Mortgage Note or the Mortgage otherwise available at law or in equity.

Section 3.16 Documents, Records and Funds in Possession of the Master Servicer and Servicers to be Held for the Trustee.

Each Servicer shall transmit to the Custodian all documents and instruments in respect of a Mortgage Loan coming into the possession of such Servicer from time to time and shall account fully to the Certificate Administrator and the Trustee for any funds received by such Servicer or which otherwise are collected by such Servicer as Liquidation Proceeds or Insurance Proceeds in respect of any Mortgage Loan. The documents constituting the servicing file shall be held by the Servicer servicing the related Mortgage Loan as custodian and bailee for the Trustee. All Mortgage Files and funds collected or held by, or under the control of, a Servicer in respect of any Mortgage Loans, whether from the collection of principal and interest

payments or from Liquidation Proceeds, including but not limited to, any funds on deposit in the related Servicer Custodial Account, shall be held by such Servicer for and on behalf of the Trustee and shall be and remain the sole and exclusive property of the Trustee, subject to the applicable provisions of this Agreement. Each Servicer also agrees that it shall not knowingly create, incur or subject any Mortgage File or any funds that are deposited in the related Servicer Custodial Account, Collection Account, Certificate Account or any Escrow Account, or any funds that otherwise are or may become due or payable to the Trustee for the benefit of the Certificateholders, to any claim, lien, security interest, judgment, levy, writ of attachment or other encumbrance created by such Servicer, or assert by legal action or otherwise any claim or right of setoff against any Mortgage File or any funds collected on, or in connection with, a Mortgage Loan, except, however, that each Servicer shall be entitled to set off against and deduct from any such funds any amounts that are properly due and payable to such Servicer under this Agreement.

Section 3.17 Servicing and Master Servicing Compensation.

Each Servicer shall be entitled out of each payment of interest (or portion thereof) on a Mortgage Loan it services to retain or withdraw from the related Servicer Custodial Account an amount equal to the Servicing Fee for such Distribution Date.

Additional servicing compensation in the form of Excess Proceeds, prepayment penalties, assumption fees, late payment charges and all income and gain net of any losses realized from Permitted Investments and all other customary and ancillary income and fees shall be retained by a Servicer to the extent not required to be deposited in the related Servicer Custodial Account pursuant to Section 3.08(b). Each Servicer shall be required to pay all expenses incurred by it in connection with its servicing activities hereunder and shall not be entitled to reimbursement therefor except as specifically provided in this Agreement.

Notwithstanding the foregoing, with respect to the payment of the Servicing Fee on any Distribution Date, the aggregate Servicing Fee for a Servicer for such Distribution Date shall be reduced (but not below zero) by an amount equal to the lesser of (a) the Prepayment Interest Shortfall for such Distribution Date relating to the Mortgage Loans it services and (b) one-twelfth of 0.25% of the aggregate Stated Principal Balance of such Mortgage Loans for such Distribution Date in the case of the Mortgage Loans serviced by National City, and one-twelfth of 0.375% of the aggregate Stated Principal Balance of such Mortgage Loans for such Distribution Date in the case of the Mortgage Loans serviced by Wells Fargo (any such reduction, “Compensating Interest”). To the extent the Servicers fail to pay Compensating Interest in respect of any Distribution Date, the Master Servicer shall deposit into the Collection Account the amount of any Compensating Interest remaining unpaid by the Servicers on any Distribution Date up to the amount the Master Servicing Fee payable to the Master Servicer on such Distribution Date.

The Master Servicer shall be entitled to retain or withdraw from the Collection Account an amount equal to the Master Servicing Fee for such Distribution Date in accordance with Section 3.11.

In addition, the Master Servicer will be entitled to all income and gain realized from any investment of funds in the Collection Account, pursuant to Section 3.08, for the performance of its activities hereunder. The Master Servicer shall be required to pay all expenses incurred by it in connection with its activities hereunder and shall not be entitled to reimbursement therefor except as otherwise provided in this Agreement.

Section 3.18 [Reserved]..

Section 3.19 [Reserved]..

Section 3.20 Advances.

Each Servicer shall determine on or before each Servicer Advance Date whether it is required to make a Periodic Advance pursuant to the definition thereof. If a Servicer determines it is required to make a Periodic Advance, it shall, on or before the Servicer Advance Date, either (a) deposit into the related Servicer Custodial Account an amount equal to the Advance and/or (b) make an appropriate entry in its records relating to the related Servicer Custodial Account that any portion of the Amount Held for Future Distribution with respect to a Loan Group in such Servicer Custodial Account has been used by such Servicer in discharge of its obligation to make any such Periodic Advance on a Mortgage Loan in such Loan Group. Any funds so applied shall be replaced by such Servicer by deposit in such Servicer Custodial Account no later than the close of business on the Business Day preceding the next Servicer Advance Date. Each Servicer shall be entitled to be reimbursed from the Servicer Custodial Account for all Advances of its own funds made pursuant to this Section 3.20 as provided in Section 3.11(a). The obligation to make Periodic Advances with respect to any Mortgage Loan shall continue until the ultimate disposition of the REO Property or Mortgaged Property relating to such Mortgage Loan. Each Servicer shall inform the Certificate Administrator and the Trustee of the amount of the Periodic Advance to be made by such Servicer with respect to each Loan Group on each Servicer Advance Date no later than the related Remittance Date.

Each Servicer shall deliver to the Master Servicer on the related Servicer Advance Date an Officer’s Certificate of a Servicing Officer indicating the amount of any proposed Periodic Advance determined by such Servicer to be a Nonrecoverable Advance. Notwithstanding anything to the contrary, no Servicer shall be required to make any Periodic Advance or Servicing Advance that would be a Nonrecoverable Advance.

If the Monthly Payment on a Mortgage Loan that was due on a related Due Date is delinquent, other than as a result of application of the Relief Act, and the amount of the Periodic Advance which the related Servicer was required to make pursuant to this Section 3.20 exceeds the amount deposited in the Collection Account by such Servicer, then an Event of Default shall have occurred with respect to such Servicer. The Master Servicer, in its capacity as successor Servicer, or another successor Servicer appointed by the Master Servicer hereunder will deposit in the Collection Account not later than the [second] Business Day immediately preceding the related Distribution Date an amount equal to such deficiency, net of the Servicing Fee (and, in the case of the Master Servicer, the Master Servicing Fee) for such Mortgage Loan, except to the extent the Master Servicer or other successor Servicer, as the case may be, determines that any such advance, if made, would be a Nonrecoverable Advance. Subject to the

foregoing, the Master Servicer or other successor Servicer, as the case may be, shall continue to make such advances through the date that the related Servicer is required to do so under this Agreement. If the Master Servicer or other successor Servicer, as the case may be, deems an advance to be a Nonrecoverable Advance, on the second Business Day prior to the related Distribution Date, the Master Servicer or such other successor Servicer shall present an Officer’s Certificate to the Certificate Administrator (i) stating that the Master Servicer or such other successor Servicer elects not to make a Periodic Advance in a stated amount and (ii) detailing the reason it deems the advance to be a Nonrecoverable Advance.

Section 3.21 Modifications, Waivers, Amendments and Consents.

(a) Except as provided in Section 3.08(a) and this Section 3.21, no Servicer shall agree to enter into, or shall enter into, any modification, waiver (other than a waiver referred to in Section 3.13, which waiver, if any, shall be governed by Section 3.13), forbearance or amendment of any term of any Mortgage Loan, unless such Mortgage Loan is a Defaulted Mortgage Loan. All modifications, waivers, forbearances or amendments of any Defaulted Mortgage Loan shall be in writing and shall be consistent with Customary Servicing Procedures.

(b) The related Servicer may, with respect to any Defaulted Mortgage Loan, agree to any modification, waiver, forbearance, or amendment of any term of such Defaulted Mortgage Loan without the consent of the Depositor, the Trustee, the Certificate Administrator, the Master Servicer, the Custodian or any Certificateholder; provided, however, that no Servicer shall agree to enter into, or shall enter into, any modification, waiver, forbearance or amendment of any Defaulted Mortgage Loan if such modification, waiver, forbearance, or amendment would:

(i) affect the amount or timing of any related payment of principal, interest or other amount payable thereunder; or

(ii) in such Servicer’s judgment, materially impair the security for such Mortgage Loan or reduce the likelihood of timely payment of amounts due thereon;

unless, in either case, such modification, waiver, forbearance or amendment is, in such Servicer’s judgment, reasonably likely to produce a greater recovery with respect to such Mortgage Loan than would liquidation. Subject to the applicable Customary Servicing Procedures, the related Servicer may permit a forbearance for a Mortgage Loan which such Servicer has been advised would default if such forbearance is not granted.

(c) Any payment of interest, which is deferred pursuant to any modification, waiver, forbearance or amendment permitted hereunder, shall not, for purposes hereof, including, without limitation, calculating monthly distributions to Certificateholders, be added to the unpaid principal balance of the related Mortgage Loan, notwithstanding that the terms of such Mortgage Loan or such modification, waiver or amendment so permit. However, interest may be capitalized in accordance with a loan modification pursuant to Section 3.21(b).

(d) The related Servicer may, to the extent permitted by applicable law or the terms of the Mortgage Loan, as a condition to granting any request by a Mortgagor for consent, modification, or amendment, the granting of which is within such Servicer’s discretion pursuant

to the Mortgage Loan and is permitted by the terms of this Agreement, require that such Mortgagor pay to such Servicer, as additional servicing compensation, a reasonable or customary fee for the additional services performed in connection with such request, together with any related costs and expenses incurred by such Servicer, which amount shall be retained by such Servicer as additional servicing compensation.

(e) Each Servicer shall notify the Depositor and the Master Servicer, in writing, of any modification or amendment of any term of any Mortgage Loan it services and the date thereof, and shall deliver to the Custodian for deposit in the related Mortgage File, an original counterpart of the agreement relating to such modification or amendment, promptly (and in any event within ten Business Days) following the execution thereof; provided, however, that if any such modification or amendment is required by applicable law to be recorded, such Servicer (i) shall deliver to the Custodian a copy thereof and (ii) shall deliver to the Custodian such document, with evidence of notification upon receipt thereof from the public recording office, if applicable.

Section 3.22 [Reserved]..

Section 3.23 [Reserved]..

Section 3.24 Master Servicer.

The Master Servicer shall supervise, monitor and oversee the obligation of the Servicers to service and administer their respective Mortgage Loans in accordance with the terms of this Agreement and shall have full power and authority to do any and all things which it may deem necessary or desirable in connection with such master servicing and administration. In performing its obligations hereunder, the Master Servicer shall act in a manner consistent with Accepted Master Servicing Practices. Furthermore, the Master Servicer shall oversee and consult with each Servicer as necessary from time to time to carry out the Master Servicer’s obligations hereunder, shall receive, review and evaluate all reports, information and other data provided to the Master Servicer by each Servicer and shall cause each Servicer to perform and observe the covenants, obligations and conditions to be performed or observed by such Servicer under this Agreement. The Master Servicer shall independently and separately monitor each Servicer’s servicing activities with respect to each related Mortgage Loan, reconcile the results of such monitoring with such information provided in the previous sentence on a monthly basis and coordinate corrective adjustments to the Servicers’ and Master Servicer’s records, and based on such reconciled and corrected information, the Master Servicer shall provide such information to the Certificate Administrator by the 15th calendar day of each month as shall be necessary in order for it to prepare the statements specified in Section 5.04, and prepare any other information and statements required to be forwarded by the Master Servicer hereunder. The Master Servicer shall reconcile the results of its Mortgage Loan monitoring with the actual remittances of the Servicers as reported to the Master Servicer.

Section 3.25 Monitoring of Servicers.

(a) The Master Servicer shall be responsible for reporting to the Trustee and the Depositor the compliance by each Servicer with its duties under this Agreement. In the review of each Servicer’s activities, the Master Servicer may rely upon an Officer’s Certificate of the Servicer (or similar document signed by an officer of the Servicer) with regard to such Servicer’s compliance with the terms of this Agreement. In the event that the Master Servicer, in its judgment, determines that a Servicer should be terminated in accordance with this Agreement, or that a notice should be sent pursuant to this Agreement with respect to the occurrence of an event that, unless cured, would constitute grounds for such termination, the Master Servicer shall notify the Depositor and the Trustee thereof, and the Master Servicer shall issue such notice or take such other action as it deems appropriate.

(b) The Master Servicer, for the benefit of the Trustee and the Certificateholders, shall enforce the obligations of each Servicer under this Agreement, and shall, in the event that a Servicer fails to perform its obligations in accordance with this Agreement, subject to the preceding paragraph and to Article VIII, terminate the rights and obligations of such Servicer hereunder and act as servicer of the related Mortgage Loans or appoint a successor Servicer; provided, however, it is understood and acknowledged by the parties hereto that there will be a period of transition (not to exceed 90 days) before the actual servicing functions (other than the advancing function required by Section 3.20 hereof) can be fully transferred to such successor Servicer. Such enforcement, including, without limitation, the legal prosecution of claims, termination of servicing 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, except as set forth below, provided that the Master Servicer shall not be required to prosecute or defend any legal action except to the extent that the Master Servicer shall have received reasonable indemnity for its costs and expenses in pursuing such action.

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

(d) The Master Servicer shall require each Servicer to comply with the remittance requirements and other obligations set forth in this Agreement.

(e) If the Master Servicer acts as Servicer, it will not assume liability for the representations and warranties of the Servicer that it replaces.

Section 3.26 Power to Act; Procedures.

The Master Servicer shall master service the Mortgage Loans and shall have full power and authority, subject to the REMIC Provisions and the provisions of Article X hereof, to do any and all things that it may deem necessary or desirable in connection with the master servicing and administration of the Mortgage Loans, including but not limited to the power and authority (i) to execute and deliver, on behalf of the Certificateholders and the Trustee, customary consents or waivers and other instruments and documents, (ii) to consent to transfers of any Mortgaged Property and assumptions of the Mortgage Notes and related Mortgages, (iii) to collect any Insurance Proceeds and Liquidation Proceeds, and (iv) to effectuate foreclosure or other conversion of the ownership of the Mortgaged Property securing any Mortgage Loan, in each case, in accordance with the provisions of this Agreement; provided, however, that the Master Servicer shall not (and, consistent with its responsibilities under Section 3.25, shall not permit any Servicer to) and each Servicer agrees that it will not knowingly or intentionally take any action, or fail to take (or fail to cause to be taken) any action reasonably within its control and the scope of duties more specifically set forth herein, that, under the REMIC Provisions, if taken or not taken, as the case may be, would cause the Trust to fail to qualify as a REMIC or result in the imposition of a tax upon the Trust (including but not limited to the tax on prohibited transactions as defined in Section 860F(a)(2) of the Code and the tax on contributions to a REMIC set forth in Section 860G(d) of the Code) unless the Master Servicer has received an Opinion of Counsel (but not at the expense of the Master Servicer) to the effect that the contemplated action would not cause the Trust to fail to qualify as a REMIC or result in the imposition of a tax upon the Trust. The Trustee shall furnish the Master Servicer, upon written request from a Servicing Officer, with any powers of attorney empowering the Master Servicer or any Servicer to execute and deliver instruments of satisfaction or cancellation, or of partial or full release or discharge, and to foreclose upon or otherwise liquidate Mortgaged Property, and to appeal, prosecute or defend in any court action relating to the Mortgage Loans or the Mortgaged Property, in accordance with this Agreement, and the Trustee shall execute and deliver such other documents, as the Master Servicer may request, to enable the Master Servicer to master service and administer the Mortgage Loans and carry out its duties hereunder, in each case in accordance with Accepted Master Servicing Practices (and the Trustee shall have no liability for misuse of any such powers of attorney by the Master Servicer or any Servicer). If the Master Servicer or the Trustee has been advised that it is likely that the laws of the state in which action is to be taken prohibit such action if taken in the name of the Trustee or that the Trustee would be adversely affected under the “doing business” or tax laws of such state if such action is taken in its name, the Master Servicer shall join with the Trustee in the appointment of a co-trustee pursuant to Section 9.09 hereof. In the performance of its duties hereunder, the Master Servicer shall be an independent contractor and shall not, except in those instances where it is taking action in the name of the Trustee, be deemed to be the agent of the Trustee.

Servicer’s Monthly Reports.

On the 10th calendar day of each month, each Servicer shall deliver to the Master Servicer a Servicer’s Certificate in substance and format mutually acceptable to each Servicer and the Master Servicer setting forth the information necessary in order for the Master Servicer to perform its reporting obligations under this Agreement.

On each Distribution Date, based solely on the information provided to the Certificate Administrator by the Master Servicer and the Servicers, the Certificate Administrator shall distribute out of the Upper-Tier Certificate Account or the Certificate Account, as applicable (to the extent funds are available therein), to each Certificateholder of record on the related Record Date (other than as provided in Section 10.01 respecting the final distribution) by wire transfer to the account at a bank or other depository institution having appropriate wire transfer facilities specified in writing by such Certificateholder to the Certificate Administrator or, if no such prior written wire transfer instruction has been provided to the Certificate Administrator, by check mailed to such Certificateholder entitled to receive a distribution on such Distribution Date at the address appearing in the Certificate Register, or by such other means of payment as such Certificateholder and the Certificate Administrator shall agree upon, such Certificateholder’s Percentage Interest in the amount to which the related Class of Certificates is entitled in accordance with the priorities set forth below in Section 5.02.

None of the Holders of any Class of Certificates, the Depositor, the Master Servicer, the Servicers, the Certificate Administrator or the Trustee shall in any way be responsible or liable to Holders of any Class of Certificates in respect of amounts properly previously distributed on any such Class.

Section 5.02

Priorities of Distributions.

(a) On each Distribution Date, based solely on the information provided to the Certificate Administrator by the Master Servicer and the Servicers, the Certificate Administrator shall withdraw from the Certificate Account (to the extent funds are available therein) (1) the amounts payable to the Master Servicer pursuant to Sections 3.11(b) and shall pay such funds to the Master Servicer and (2) the Pool Distribution Amount for each Loan Group, and shall apply such funds, first, to distributions in respect of the Uncertificated Lower-Tier Regular Interests for deposit in the Upper-Tier Certificate Account, as specified in this Section 5.02(a) and then from the Upper-Tier Certificate Account to distributions on the Certificates, paying priorities (i) through (ii) to each Group from the applicable Pool Distribution Amount and priorities (iii) and

(iv) from the remaining combined Pool Distribution Amounts, in the following order of priority and to the extent of such funds:

(i) to each Class of Senior Certificates of such Loan Group, an amount allocable to interest equal to the Interest Distribution Amount for such Class and any shortfall being allocated among such Classes in proportion to the amount of the Interest Distribution Amount that would have been distributed in the absence of such shortfall;

(ii) to the Senior Certificates of a Group, in an aggregate amount up to the Senior Principal Distribution Amount for such Group, such distribution to be allocated among such Classes in accordance with Section 5.02(b);

(A) to the Class B-1 Certificates, an amount allocable to interest equal to the Interest Distribution Amount for such Class for such Distribution Date;

(B) to the Class B-1 Certificates, an amount allocable to principal equal to its Pro Rata Share for such Distribution Date until the Class Certificate Balance thereof has been reduced to zero;

(C) to the Class B-2 Certificates, an amount allocable to interest equal to the Interest Distribution Amount for such Class for such Distribution Date;

(D) to the Class B-2 Certificates, an amount allocable to principal equal to its Pro Rata Share for such Distribution Date until the Class Certificate Balance thereof has been reduced to zero;

(E) to the Class B-3 Certificates, an amount allocable to interest equal to the Interest Distribution Amount for such Class for such Distribution Date;

(F) to the Class B-3 Certificates, an amount allocable to principal equal to its Pro Rata Share for such Distribution Date until the Class Certificate Balance thereof has been reduced to zero;

(G) to the Class B-4 Certificates, an amount allocable to interest equal to the Interest Distribution Amount for such Class for such Distribution Date;

(H) to the Class B-4 Certificates, an amount allocable to principal equal to its Pro Rata Share for such Distribution Date until the Class Certificate Balance thereof has been reduced to zero;

(I) to the Class B-5 Certificates, an amount allocable to interest equal to the Interest Distribution Amount for such Class for such Distribution Date;

(J) to the Class B-5 Certificates, an amount allocable to principal equal to its Pro Rata Share for such Distribution Date until the Class Certificate Balance thereof has been reduced to zero;

(iv) to the Holder of the Class 1-A-R Certificates, any amounts remaining in the Upper-Tier Certificate Account.

No Class of Certificates will be entitled to any distributions with respect to the amount payable pursuant to clause (ii) of the definition of “Interest Distribution Amount” after its Class Certificate Balance has been reduced to zero.

All distributions in respect of the Interest Distribution Amount for a Class will be applied first with respect to the amount payable pursuant to clause (i) of the definition of “Interest Distribution Amount,” and second with respect to the amount payable pursuant to clause (ii) of such definition.

Distributions on the Uncertificated Lower-Tier Regular Interests. On each Distribution Date the Trustee shall be deemed to distribute to itself, as the holder of the Uncertificated Lower-Tier Regular Interests, the Lower-Tier Distribution Amount in the amounts and with the priorities set forth in the definition thereof.

Realized Losses shall be allocated among the Uncertificated Lower-Tier Regular Interests as specified in the definition of Lower-Tier Realized Losses.

Subsequent Recoveries shall be applied to the Uncertificated Lower-Tier Regular Interests in a manner analogous to the application of Realized Losses of the Uncertificated Lower-Tier Regular Interests.

For federal income tax purposes, the Pass-Through Rate for the Class B-1, Class B-2, Class B-3, Class B-4, Class B-5 and Class B-6 Certificates for any Distribution Date shall be expressed as a per annum rate equal to the weighted average of the Uncertificated Pass-Through Rates for Uncertificated Lower-Tier Regular Interests Y-1, Y-2, Y-3 and Y-4, weighted, for each of the foregoing determinations, on the basis of the respective Uncertificated Principal Balance of each such Uncertificated Lower-Tier Regular Interest (computed to eight decimal places), immediately prior to such Distribution Date.

(b)

(i)

With respect to the Class A Certificates of Loan Group 1:

On each Distribution Date prior to the Senior Credit Support Depletion Date, the amount distributable to the Related Group for Loan Group 1 pursuant to Section 5.02(a)(ii) for

such Distribution Date, will be distributed based solely on the information contained in each Servicer’s Certificate in the following order of priority:

first, to the Class 1-A-R Certificates in respect of Component I thereof until its Class Certificate Balance has been reduced to zero;

second, concurrently, to the Class 1-A-1 Certificates and the Class 1-A-2 Certificates, pro rata, until their Class Certificate Balances have been reduced to zero.

(ii) With respect to the Class A Certificates of Loan Group 2:

On each Distribution Date prior to the Senior Credit Support Depletion Date, the amount distributable to the Related Group for Loan Group 2 pursuant to Section 5.02(a)(ii) for such Distribution Date, will be distributed to the Class 2-A-1 Certificates and Class 2-A-2 Certificates, pro rata, until their Class Certificate Balances have been reduced to zero.

(iii) With respect to the Class A Certificates of Loan Group 3:

On each Distribution Date prior to the Senior Credit Support Depletion Date, the amount distributable to the Related Group for Loan Group 3 pursuant to Section 5.02(a)(ii) for such Distribution Date, will be distributed to the Class 3-A-1 Certificates and Class 3-A-2 Certificates, pro rata, until their Class Certificate Balances have been reduced to zero.

(iv) With respect to the Class A Certificates of Loan Group 4:

On each Distribution Date prior to the Senior Credit Support Depletion Date, the amount distributable to the Related Group for Loan Group 4 pursuant to Section 5.02(a)(ii) for such Distribution Date, will be distributed to the Class 4-A-1 Certificates and Class 4-A-2 Certificates, pro rata, until their Class Certificate Balances have been reduced to zero.

(v) Notwithstanding the foregoing, on each Distribution Date prior to the Senior Credit Support Depletion Date but on or after the date on which the aggregate Class Certificate Balance of the Class A Certificates of a Group have been reduced to zero, amounts otherwise distributable from the Unscheduled Principal Amounts for the Related Loan Group on the Subordinate Certificates will be paid as principal to the remaining classes of Class A Certificates in accordance with the priorities set forth for the applicable Group in (i), (ii), (iii) or (iv) above, provided that on such Distribution Date (a) the Aggregate Subordinate Percentage for such Distribution Date is less than twice the initial Aggregate Subordinate Percentage or (b) the outstanding principal balance of all Mortgage Loans (including, for this purpose, any Mortgage Loans in foreclosure or any REO Property and any Mortgage Loan for which the mortgagor has filed for bankruptcy) delinquent 60 days or more (averaged over the preceding six-month period), as a percentage of the aggregate Class Certificate Balance of the Subordinate Certificates, is greater than or equal to 50%. If the Class A Certificates of two or more Groups remain outstanding, the distributions described above will be made to the Class A Certificates of such Groups, pro rata, in proportion to the aggregate Class Certificate Balance of the Class A Certificates of each such Group. In addition, if on any Distribution Date the aggregate Class Certificate Balance of the Class A Certificates of a Group is greater than the Adjusted Pool Amount of the related Loan Group (any such Group, the “Undercollateralized Group” and any

such excess, the “Undercollateralized Amount”), all amounts otherwise distributable as principal on the Subordinate Certificates pursuant to 5.02(a)(iii)(L), (J), (H), (F), (D) and (B), in that order, will be paid as principal to the Class A Certificates of the Undercollateralized Group in accordance with the priorities set forth for the applicable Group above under (i), (ii), (iii) or (iv) until the aggregate Class Certificate Balance of the Class A Certificates of the Undercollateralized Group equals the Adjusted Pool Amount of the related Loan Group. The amount of any Class Unpaid Interest Shortfalls with respect to the Undercollateralized Group (including any Class Unpaid Interest Shortfalls for such Distribution Date) will be paid to the Undercollateralized Group prior to the payment of any Undercollateralized Amount from amounts otherwise distributable as principal on the Subordinate Certificates pursuant to Section 5.02(a)(iii)(L), (J), (H), (F), (D) and (B), in that order: such amount will be paid to such Undercollateralized Group in accordance with the priorities set forth in Section 5.02(a)(i) up to their Interest Distribution Amounts for such Distribution Date. If two or more Groups are Undercollateralized Groups, the distributions described above will be made, pro rata, in proportion to the amount by which the aggregate Class Certificate Balance of the Class A Certificates of each such Group exceeds the Adjusted Pool Amount of the related Loan Group.

On each Distribution Date on or after the Senior Credit Support Depletion Date, notwithstanding the allocation and priority set forth above, the portion of the Pool Distribution Amount with respect to a Loan Group available to be distributed as principal of the Class A Certificates of the Related Group shall be distributed concurrently, as principal, on such Classes, pro rata, on the basis of their respective Class Certificate Balances, until the Class Certificate Balances thereof are reduced to zero.

(c) On each Distribution Date, Accrued Certificate Interest for each Class of Certificates for such Distribution Date shall be reduced by such Class’s pro rata share, based on such Class’s Interest Distribution Amount for such Distribution Date, without taking into account the allocation made by this Section 5.02(c), of (A) Non-Supported Interest Shortfalls, and (B) each Relief Act Reduction incurred during the calendar month preceding the month of such Distribution Date. In addition, on each Distribution Date on and after the Senior Credit Support Depletion Date, Accrued Certificate Interest for each Class of Certificates relating to a Loan Group for such Distribution Date also shall be reduced by such Class’s pro rata share, based on such Class’s Interest Distribution Amount for such Distribution Date, without taking into account the allocation made by this Section 5.02(c), of any Realized Loss on a Mortgage Loan in the Related Loan Group allocable to interest.

(d) Notwithstanding the priority and allocation contained in Section 5.02(a)(iii), if with respect to any Class of Subordinate Certificates on any Distribution Date, (i) the aggregate of the Class Certificate Balances immediately prior to such Distribution Date of all Classes of Subordinate Certificates which have a higher numerical Class designation than such Class, divided by (ii) the aggregate Pool Stated Principal Balance for all Loan Groups immediately prior to such Distribution Date (the “Fractional Interest”) is less than the Original Fractional Interest for such Class, no Unscheduled Principal Payments will be made to any Classes junior to such Class (the “Restricted Classes”) and the Class Certificate Balances of the Restricted Classes will not be used in determining the Pro Rata Share for the Subordinate Certificates that are not Restricted Classes. Any funds remaining will be distributed in the order provided in Section 5.02(a)(iii).

Section 5.03

Allocation of Losses.

(a) On or prior to the 10th calendar day of each month, each Servicer shall inform the Master Servicer in writing with respect to each Mortgage Loan it services: (1) whether any Realized Loss is a Deficient Valuation or a Debt Service Reduction, (2) of the amount of such loss or Deficient Valuation, or of the terms of such Debt Service Reduction and (3) of the total amount of Realized Losses. The Master Servicer shall provide such information to the Certificate Administrator and, based on such information, the Certificate Administrator shall determine and allocate the total amount of Realized Losses with respect to the related Distribution Date. Realized Losses shall be allocated to the Certificates by a reduction in the Class Certificate Balances of the designated Classes pursuant to Section 5.03(b) below.

(b) The Class Certificate Balance of the Class of Subordinate Certificates then outstanding with the highest numerical Class designation shall be reduced on each Distribution Date by the amount, if any, necessary such that the aggregate of the Class Certificate Balances of all outstanding Classes of Certificates (after giving effect to the amount to be distributed as a distribution of principal and the allocation of Realized Losses on such Distribution Date) equals the sum of the Adjusted Pool Amounts for such Distribution Date.

After the Senior Credit Support Depletion Date, the Class Certificate Balances of the Senior Certificates of the Related Loan Group in the aggregate shall be reduced on each Distribution Date by the amount, if any, by which the aggregate of the Class Certificate Balances of all outstanding Senior Certificates of such Related Loan Group (after giving effect to the amount to be distributed as a distribution of principal and the allocation of Realized Losses on the Mortgage Loans in the Related Loan Group on such Distribution Date) exceeds the Adjusted Pool Amount for such Loan Group and such Distribution Date.

Any such reduction shall be allocated among the Classes of Senior Certificates of the Related Group pro rata based on the Class Certificate Balances immediately prior to such Distribution Date.

(c) Any Realized Loss allocated to a Class of Certificates or any reduction in the Class Certificate Balance of a Class of Certificates pursuant to Section 5.03(b) above shall be allocated among the Certificates of such Class pro rata in proportion to their respective Percentage Interests.

(d) The calculation of the amount to be distributed as principal to any Class of Certificates with respect to a Distribution Date (the “Calculated Principal Distribution”) shall be made prior to the allocation of any Realized Losses for such Distribution Date; provided, however, that the actual distribution of principal to the Classes of Certificates shall be made subsequent to the allocation of Realized Losses for such Distribution Date. In the event that after the allocation of Realized Losses for a Distribution Date, the Calculated Principal Distribution for a Class of Subordinated Certificates is greater than the Class Certificate Balance of such Class, the excess shall be distributed pro rata to the Classes of Subordinate Certificates in accordance with their remaining Class Certificate Balances.

(e) After the Senior Credit Support Depletion Date, on any Distribution Date on which the Class 1-A-2 Loss Allocation Amount is greater than zero, the Class Certificate Balance of the Class 1-A-2 Certificates will be reduced by the Class 1-A-2 Loss Allocation Amount and, notwithstanding Section 5.03(b), the Class Certificate Balance of the Class 1-A-1 Certificates will not be reduced by the Class 1-A-2 Loss Allocation Amount. After the Senior Credit Support Depletion Date, on any Distribution Date on which the Class 2-A-2 Loss Allocation Amount is greater than zero, the Class Certificate Balance of the Class 2-A-2 Certificates will be reduced by the Class 2-A-2 Loss Allocation Amount and, notwithstanding Section 5.03(b), the Class Certificate Balances of the Class 2-A-1 Certificates will not be reduced by the Class 2-A-2 Loss Allocation Amount. After the Senior Credit Support Depletion Date, on any Distribution Date on which the Class 3-A-2 Loss Allocation Amount is greater than zero, the Class Certificate Balance of the Class 3-A-2 Certificates will be reduced by the Class 3-A-2 Loss Allocation Amount and, notwithstanding Section 5.03(b), the Class Certificate Balance of the Class 3-A-1 Certificates will not be reduced by the Class 3-A-2 Loss Allocation Amount. After the Senior Credit Support Depletion Date, on any Distribution Date on which the Class 4-A-2 Loss Allocation Amount is greater than zero, the Class Certificate Balance of the Class 4-A-2 Certificates will be reduced by the Class 4-A-2 Loss Allocation Amount and, notwithstanding Section 5.03(b), the Class Certificate Balance of the Class 4-A-1 Certificates will not be reduced by the Class 4-A-2 Loss Allocation Amount.

(f) If, after taking into account any Subsequent Recoveries, the amount of a Realized Loss is reduced, the amount of such Subsequent Recoveries will be applied to increase the Class Certificate Balance of the Class of Certificates with the highest payment priority to which Realized Losses have been allocated, but not by more than the amount of Realized Losses previously allocated to that Class of Certificates pursuant to this Section 5.03. The amount of any remaining Subsequent Recoveries will be applied to sequentially increase the Class Certificate Balance of the Certificates, beginning with the Class of Certificates with the next highest payment priority, up to the amount of such Realized Losses previously allocated to such Class or Classes of Certificates pursuant to this Section 5.03. Holders of such Certificates will not be entitled to any payments in respect of current interest on the amount of such increases for any Interest Accrual Period preceding the Distribution Date on which such increase occurs. Any such increases shall be applied to the Class Certificate Balance of each Certificate of such Class in accordance with its respective Fractional Interest.

(g) Notwithstanding any other provision of this Section 5.03, no Class Certificate Balance of a Class will be increased on any Distribution Date such that the Class Certificate Balance of such Class exceeds its Initial Class Certificate Balance less all distributions of principal previously distributed in respect of such Class on prior Distribution Dates.

Section 5.05

(a) For federal income tax purposes, each REMIC shall have a calendar year taxable year and shall maintain its books on the accrual method of accounting.

(b) The Certificate Administrator shall prepare or cause to be prepared, shall cause to be timely signed by the Trustee, and shall file or cause to be filed with the Internal Revenue Service and applicable state or local tax authorities income tax information returns for each taxable year with respect to each REMIC containing such information at the times and in the manner as may be required by the Code, the Treasury Regulations or state or local tax laws, regulations, or rules, and shall furnish or cause to be furnished to each REMIC and the Certificateholders the schedules, statements or information at such times and in such manner as may be required thereby. Within 30 days of the Closing Date, the Certificate Administrator shall furnish or cause to be furnished to the Internal Revenue Service, on Form 8811 or as otherwise required by the Code or the Treasury Regulations, the name, title, address and telephone number of the person that Holders of the Certificates may contact for tax information relating thereto, together with such additional information at the time or times and in the manner required by the Code or the Treasury Regulations.

Section 5.06 Tax Matters Person. The Tax Matters Person shall have the same duties with respect to each REMIC as those of a “tax matters partner” under Subchapter C of Chapter 63 of Subtitle F of the Code. The Seller, as Holder of a Percentage Interest in the Class 1-A-R Certificates, is hereby designated as the Tax Matters Person for the Upper-Tier REMIC and the Lower-Tier REMIC. By its acceptance of a Class 1-A-R Certificate, each Holder thereof irrevocably appoints the Certificate Administrator to act as agent for the Tax Matters Person for the Upper-Tier REMIC and the Lower-Tier REMIC, except that the Certificate Administrator shall not be required to pay any taxes.

Section 5.07 Rights of the Tax Matters Person in Respect of the Certificate Administrator. The Certificate Administrator shall afford the Tax Matters Person, upon reasonable notice during normal business hours, access to all records maintained by the Certificate Administrator in respect of its duties hereunder and access to officers of the

Certificate Administrator responsible for performing such duties. The Certificate Administrator shall make available to the Tax Matters Person such books, documents or records relating to the Certificate Administrator’s services hereunder as the Tax Matters Person shall reasonably request. The Tax Matters Person shall not have any responsibility or liability for any action or failure to act by the Certificate Administrator and is not obligated to supervise the performance of the Certificate Administrator under this Agreement or otherwise.

Section 5.08 REMIC Related Covenants. For as long as the Trust shall exist, the Trustee, the Certificate Administrator, the Depositor and each Servicer shall act in accordance herewith to assure continuing treatment of the Upper-Tier REMIC and the Lower-Tier REMIC as REMICs and avoid the imposition of tax on either REMIC. In particular:

(a) The Trustee shall not create, or permit the creation of, any “interests” in either REMIC within the meaning of Code Section 860D(a)(2) other than the interests represented by the Regular Certificates, the Residual Certificates and the Uncertificated Lower-Tier Regular Interests.

(b) Except as otherwise provided in the Code, (i) the Depositor and each Servicer shall not contribute to the Trust Estate and the Custodian, on behalf of the Trustee, and the Trustee shall not accept property unless substantially all of the property held in each REMIC constitutes either “qualified mortgages” or “permitted investments” as defined in Code Sections 860G(a)(3) and (5), respectively, and (ii) no property shall be contributed to each REMIC after the start-up day unless such contribution would not subject the Trust Estate to the 100% tax on contributions to a REMIC after the start-up day of the REMIC imposed by Code Section 860G(d).

(c) Except as otherwise provided in this Agreement, neither the Trustee nor the Certificate Administrator shall accept on behalf of either REMIC any fee or other compensation for services and none of the Certificate Administrator, the Trustee or any Servicer shall knowingly accept, on behalf of the Trust Estate any income from assets other than those permitted to be held by a REMIC.

(d) Neither the Servicers, the Trustee, nor the Certificate Administrator shall sell or permit the sale of all or any portion of the Mortgage Loans (other than in accordance with Sections 2.02, 2.04 or 3.14(b)), unless such sale is pursuant to a “qualified liquidation” of the applicable REMIC as defined in Code Section 860F(a)(4)(A) and in accordance with Article X.

(e) The Certificate Administrator shall maintain books with respect to the Trust and each REMIC on a calendar year taxable year and on an accrual basis.

None of the Master Servicer, the Servicers, the Certificate Administrator or the Trustee shall engage in a “prohibited transaction” (as defined in Code Section 860F(a)(2)), except that, with the prior written consent of the Servicer and the Depositor, the Trustee or the Certificate Administrator may engage in the activities otherwise prohibited by the foregoing paragraphs (b), (c) and (d); provided that the Servicers shall have delivered to the Trustee and the Certificate Administrator an Opinion of Counsel to the effect that such transaction will not result in the imposition of a tax on either the Upper-Tier REMIC or the Lower-Tier REMIC and will

not disqualify either REMIC from treatment as a REMIC; and, provided further, that the Servicers shall have demonstrated to the satisfaction of the Trustee and the Certificate Administrator that such action will not adversely affect the rights of the Holders of the Certificates, the Certificate Administrator, or the Trustee and that such action will not adversely impact the rating of the Certificates.

ARTICLE VI

The Subordinate Certificates shall be available to investors in interests representing minimum dollar Certificate Balances of $10,000 and integral dollar multiples of $1 in excess thereof (except one Certificate of such Class may be issued with a different Certificate Balance). Other than the 0.01% Percentage Interest in the Class 1-A-R Certificates to be held by the Seller, the minimum denomination of the Class 1-A-R Certificates will be 20% of the Percentage Interest of the Class 1-A-R Certificates.

The Certificates shall be executed by manual or facsimile signature on behalf of the Trustee by an authorized officer or signatory. Certificates bearing the manual or facsimile signatures of individuals who were, at the time when such signatures were affixed, authorized to sign on behalf of the Trustee shall bind the Trustee, notwithstanding that such individuals or any of them have ceased to be so authorized prior to the execution and delivery of such Certificates or did not hold such offices or positions at the date of such Certificate. No Certificate shall be entitled to any benefit under this Agreement, or be valid for any purpose, unless such Certificate shall have been manually countersigned by the Trustee substantially in the form provided for herein, and such countersignature upon any Certificate shall be conclusive evidence, and the only evidence, that such Certificate has been duly authenticated and delivered hereunder. All Certificates shall be dated the date of their countersignature.

Section 6.02

Registration of Transfer and Exchange of Certificates.

(a) The Certificate Administrator shall cause to be kept at an office or agency in the city in which the Corporate Trust Office of the Certificate Administrator is located a Certificate Register in which, subject to such reasonable regulations as it may prescribe, the Certificate Administrator shall provide for the registration of Certificates and of transfers and exchanges of Certificates as herein provided. The Certificate Administrator shall initially serve

as Certificate Registrar for the purpose of registering Certificates and transfers and exchanges of Certificates as herein provided.

(b) At the option of the Certificateholders, Certificates may be exchanged for other Certificates of authorized denominations of the same Class and aggregate Percentage Interest, upon surrender of the Certificates to be exchanged at any such office or agency. Whenever any Certificates are so surrendered for exchange, the Trustee shall execute and the Trustee shall authenticate, countersign and deliver the Certificates which the Certificateholder making the exchange is entitled to receive. Every Certificate presented or surrendered for transfer or exchange shall be duly endorsed by, or be accompanied by a written instrument of transfer in form satisfactory to the Certificate Registrar duly executed by, the Holder thereof or its attorney duly authorized in writing.

(c) (i) Except as provided in paragraph (c)(iii) below, the Book-Entry Certificates shall at all times remain registered in the name of the Depository or its nominee and at all times: (A) registration of the Certificates may not be transferred except to another Depository; (B) the Depository shall maintain book-entry records with respect to the Certificate Owners and with respect to ownership and transfers of such Book-Entry Certificates; (C) ownership and transfers of registration of the Book-Entry Certificates on the books of the Depository shall be governed by applicable rules established by the Depository; (D) the Depository may collect its usual and customary fees, charges and expenses from its Depository Participants; (E) the Depository shall be the representative of the Certificate Owners of the Book-Entry Certificates for purposes of exercising the rights of Holders under this Agreement, and requests and directions for and votes of the Depository shall not be deemed to be inconsistent if they are made with respect to different Certificate Owners; and (F) the Certificate Administrator may rely and shall be fully protected in relying upon information furnished by the Depository with respect to its Depository Participants and furnished by the Depository Participants with respect to indirect participating firms and persons shown on the books of such indirect participating firms as direct or indirect Certificate Owners.

(ii) All transfers by Certificate Owners of Book-Entry Certificates shall be made in accordance with the procedures established by the Depository Participant or brokerage firm representing such Certificate Owner. Each Depository Participant shall only transfer Book-Entry Certificates of Certificate Owners it represents or of brokerage firms for which it acts as agent in accordance with the Depository’s normal procedures.

(iii) If (A) (1) the Depositor advises the Certificate Administrator in writing that the Depository is no longer willing or able to properly discharge its responsibilities as Depository, and (2) the Certificate Administrator or the Depositor is unable to locate a qualified successor, or (B) to the extent permitted by law, the Depositor at its option advises the Certificate Administrator in writing that it elects to terminate the book-entry system through the Depository, the Certificate Administrator shall notify all Certificate Owners, through the Depository, of the occurrence of any such event and of the availability of definitive, fully-registered Certificates (the “Definitive Certificates”) to Certificate Owners. Upon surrender to the Certificate Administrator of the related Class of Certificates by the Depository, accompanied by the instructions from the Depository

for registration, the Certificate Administrator shall prepare the Definitive Certificates, which will be executed and authenticated by the Trustee pursuant to clause (b) above. None of the Servicers, the Depositor, the Certificate Administrator or the Trustee shall be liable for any delay in delivery of such instruction and may conclusively rely on, and shall be protected in relying on, such instructions. The Depositor shall provide the Certificate Administrator with an adequate inventory of certificates to facilitate the issuance and transfer of Definitive Certificates. Upon the issuance of Definitive Certificates, the Holders of the Definitive Certificates shall be recognized as Certificateholders hereunder.

(d) No transfer of a Private Certificate shall be made unless such transfer is exempt from the registration requirements of the 1933 Act and any applicable state securities laws or is made in accordance with the 1933 Act and such laws. In the event of any such transfer, (i) unless such transfer is made in reliance on Rule 144A under the 1933 Act, the Certificate Administrator or the Depositor may require a written Opinion of Counsel (which may be in-house counsel) acceptable to and in form and substance reasonably satisfactory to the Certificate Administrator and the Depositor that such transfer may be made pursuant to an exemption, describing the applicable exemption and the basis therefor, from the 1933 Act and such laws or is being made pursuant to the 1933 Act and such laws, which Opinion of Counsel shall not be an expense of the Certificate Administrator or the Depositor and (ii) the Certificate Administrator shall require a certificate from the Certificateholder desiring to effect such transfer substantially in the form attached hereto as Exhibit G-1 and a certificate from such Certificateholder’s prospective transferee substantially in the form attached hereto either as Exhibit G-2A or as Exhibit G-2B, which certificates shall not be an expense of the Certificate Administrator or the Depositor; provided that the foregoing requirements under clauses (i) and (ii) shall not apply to a transfer of a Private Certificate between or among the Depositor, the Seller, the Servicers, their affiliates or both. The Depositor shall provide to any Holder of a Private Certificate and any prospective transferees designated by any such Holder, information regarding the related Certificates and the Mortgage Loans and such other information as shall be necessary to satisfy the condition to eligibility set forth in Rule 144A(d)(4) for transfer of any such certificate without registration thereof under the 1933 Act pursuant to the registration exemption provided by Rule 144A. The Holder of a Private Certificate desiring to effect such transfer shall, and does hereby agree to, indemnify the Master Servicer, the Certificate Administrator, each Servicer, the Trustee and the Depositor against any liability that may result if the transfer is not so exempt or is not made in accordance with such federal and state laws.

(e) No transfer of an ERISA Restricted Certificate or a Residual Certificate shall be made unless the transferee delivers to the Certificate Administrator either (i) a representation letter in the form of Exhibit H from the transferee of such Certificate, which representation letter shall not be an expense of the Depositor, the Certificate Administrator, the Trustee, the Master Servicer or the Servicers, or (ii) in the case of any ERISA Restricted Certificate presented for registration in the name of an employee benefit plan or arrangement, including an individual retirement account, subject to Title I of ERISA, Section 4975 of the Code, or any federal, state or local law which is similar to Section 406 of ERISA or Section 4975 of the Code (“Similar Law”) (collectively, a “Plan”), or a trustee or custodian of any of the foregoing, an Opinion of Counsel for the benefit of the Trustee, Servicers, the Master Servicer and the Certificate Administrator upon which they may rely that the purchase of the ERISA

Restricted Certificate is permissible under local law, will not constitute or result in a non-exempt prohibited transaction under Section 406 of ERISA, Section 4975 of the Code or Similar Law, and will not subject the Certificate Administrator, the Trustee, the Master Servicer or the Servicers to any obligation or liability in addition to those undertaken in this Agreement, which Opinion of Counsel shall not be an expense of the Certificate Administrator, the Trustee, the Master Servicer or the Servicers. Any transferee of an ERISA Restricted Certificate that does not comply with either clause (i) or (ii) of the preceding sentence will be deemed to have made one of the representations set forth in Exhibit H. Notwithstanding anything else to the contrary herein, any purported transfer of a Residual Certificate to or on behalf of a Plan shall be void and of no effect. Notwithstanding anything else to the contrary herein, any purported transfer of an ERISA Restricted Certificate to or on behalf of a Plan without the delivery to the Certificate Administrator, the Trustee, the Master Servicer and the Servicers of an Opinion of Counsel satisfactory to the Certificate Administrator and the Servicers as described above shall be void and of no effect.

None of the Trustee, the Certificate Administrator, the Servicers, the Master Servicer or the Certificate Registrar shall have any liability for transfers of Book-Entry Certificates made through the book-entry facilities of the Depository or between or among any Depository Participants or Certificate Owners, made in violation of applicable restrictions. The Certificate Administrator and the Trustee may rely and shall be fully protected in relying upon information furnished by the Depository with respect to its Depository Participants and furnished by the Depository Participants with respect to indirect participating firms and Persons shown on the books of such indirect participating firms as direct or indirect Certificate Owners.

To the extent permitted under applicable law (including, but not limited to, ERISA), none of the Depositor, the Certificate Administrator, the Master Servicer or the Trustee shall be under any liability to any Person for any registration of transfer of any ERISA Restricted Certificate that is in fact not permitted by this Section 6.02 or for making any payments due on such Certificate to the Holder thereof or taking any other action with respect to such Holder under the provisions of this Agreement so long as the transfer was registered by the Certificate Registrar in accordance with the foregoing requirements.

(f) Each Person who has or who acquires any Ownership Interest in a Residual Certificate shall be deemed by the acceptance or acquisition of such Ownership Interest to have agreed to be bound by the following provisions, and the rights of each Person acquiring any Ownership Interest in a Residual Certificate are expressly subject to the following provisions:

(i) Each Person holding or acquiring any Ownership Interest in a Residual Certificate shall be a Permitted Transferee and shall promptly notify the Certificate Administrator of any change or impending change in its status as a Permitted Transferee.

(ii) No Person shall acquire an Ownership Interest in a Residual Certificate unless such Ownership Interest is a pro rata undivided interest.

(iii) In connection with any proposed transfer of any Ownership Interest in a Residual Certificate, the proposed transferee shall deliver to the Certificate

Administrator, in form and substance satisfactory to the Certificate Administrator, an affidavit in the form of Exhibit I-1 hereto, and the proposed transferor shall deliver to the Certificate Administrator, in form and substance satisfactory to the Certificate Administrator, a transferor certificate in the form of Exhibit I-2 hereto.

(iv) Notwithstanding the delivery of an affidavit by a proposed transferee under clause (iii) above, if a Responsible Officer of the Certificate Administrator has actual knowledge that the proposed transferee is not a Permitted Transferee, no transfer of any Ownership Interest in a Residual Certificate to such proposed transferee shall be effected by the Certificate Administrator.

(v) No Ownership Interest in a Residual Certificate may be purchased by or transferred to any Person that is not a U.S. Person, unless (A) such Person holds such Residual Certificate in connection with the conduct of a trade or business within the United States and furnishes the transferor, the Depositor and the Certificate Administrator with an effective Internal Revenue Service Form W-8ECI (or successor thereto) or (B) the transferee delivers to the transferor, the Depositor and the Certificate Administrator an Opinion of Counsel from a nationally-recognized tax counsel to the effect that such transfer is in accordance with the requirements of the Code and the regulations promulgated thereunder and that such transfer of a Residual Certificate will not be disregarded for federal income tax purposes.

(vi) Any attempted or purported transfer of any Ownership Interest in a Residual Certificate in violation of the provisions of this Section 6.02 shall be absolutely null and void and shall vest no rights in the purported transferee. If any purported transferee shall, in violation of the provisions of this Section 6.02, become a Holder of a Residual Certificate, then the prior Holder of such Residual Certificate that is a Permitted Transferee shall, upon discovery that the registration of transfer of such Residual Certificate was not in fact permitted by this Section 6.02, be restored to all rights as Holder thereof retroactive to the date of registration of transfer of such Residual Certificate. The Certificate Administrator shall be under no liability to any Person for any registration of transfer of a Residual Certificate that is in fact not permitted by this Section 6.02 or for making any distributions due on such Residual Certificate to the Holder thereof or taking any other action with respect to such Holder under the provisions of the Agreement so long as the transfer was registered in accordance with this Section 6.02. The Certificate Administrator and the Depositor shall be entitled to recover from any Holder of a Residual Certificate that was in fact not a Permitted Transferee at the time such distributions were made all distributions made on such Residual Certificate. Any such distributions so recovered by the Certificate Administrator or the Depositor shall be distributed and delivered by the Certificate Administrator to the prior Holder of such Residual Certificate that is a Permitted Transferee.

(vii) If any Person other than a Permitted Transferee acquires any Ownership Interest in a Residual Certificate in violation of the restrictions in this Section 6.02, then the Certificate Administrator, based on information provided to the Certificate Administrator by each Servicer, will provide to the Internal Revenue Service, and to the Persons specified in Section 860E(e)(3) and (6) of the Code, information needed to

compute the tax imposed under Section 860E(e) of the Code on transfers of residual interests to disqualified organizations. The expenses of the Certificate Administrator under this clause (vii) shall be reimbursable by the Trust.

(viii) No Ownership Interest in a Residual Certificate shall be acquired by a Plan or any Person acting on behalf of a Plan.

(h) No service charge shall be imposed for any transfer or exchange of Certificates of any Class, but the Certificate Registrar may require payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any transfer or exchange of Certificates.

(i) All Certificates surrendered for transfer and exchange shall be destroyed by the Certificate Registrar.

Section 6.03 Mutilated, Destroyed, Lost or Stolen Certificates. If (a) any mutilated Certificate is surrendered to the Certificate Registrar or the Certificate Registrar receives evidence to its satisfaction of the destruction, loss or theft of any Certificate, and (b) there is delivered to the Certificate Administrator, the Trustee, the Depositor and the Certificate Registrar such security or indemnity reasonably satisfactory to each, to save each of them harmless, then, in the absence of actual notice to the Certificate Administrator, the Trustee or the Certificate Registrar that such Certificate has been acquired by a protected purchaser, the Trustee shall execute and authenticate and the Certificate Registrar shall deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a new Certificate of the same Class and Percentage Interest but bearing a number not contemporaneously outstanding. Upon the issuance of any new Certificate under this Section, the Certificate Registrar may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Certificate Registrar) connected therewith. Any duplicate Certificate issued pursuant to this Section shall constitute complete and indefeasible evidence of ownership in the Trust, as if originally issued, whether or not the lost, stolen or destroyed Certificate shall be found at any time.

Section 6.04 Persons Deemed Owners. Prior to due presentation of a Certificate for registration of transfer, the Depositor, the Servicers, the Certificate Administrator, the Trustee, the Certificate Registrar and any agent of the Depositor, the Servicers, the Certificate Administrator, the Trustee or the Certificate Registrar may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions pursuant to Section 5.01 and for all other purposes whatsoever, and none of the Depositor, the Servicers, the Master Servicer, the Certificate Administrator, the Trustee, the Certificate Registrar or any agent of the Depositor, the Servicers, the Certificate Administrator, the Trustee or the Certificate Registrar shall be affected by notice to the contrary.

By way of illustration and not limitation, the Depositor is not liable for the servicing and administration of the Mortgage Loans, nor is it obligated by Section 8.01 to assume any obligations of either Servicer or to appoint a designee to assume such obligations, nor is it liable for any other obligation hereunder that it may, but is not obligated to, assume unless it elects to assume such obligation in accordance herewith.

Section 7.02 Merger or Consolidation of the Depositor, the Master Servicer or a Servicer. The Depositor, the Master Servicer and each Servicer will each keep in full effect its existence, rights and franchises as a separate entity under the laws governing its organization, and will each obtain and preserve its qualification to do business as a foreign corporation in each jurisdiction in which such qualification is or shall be necessary to protect the validity and enforceability of this Agreement, the Certificates or any of the Mortgage Loans and to perform its respective duties under this Agreement.

Any Person into which the Depositor, the Master Servicer or either Servicer may be merged or consolidated, or any corporation resulting from any merger or consolidation to which the Depositor, the Master Servicer or such Servicer shall be a party, or any Person succeeding to the business of the Depositor, the Master Servicer or such Servicer, shall be the successor of the Depositor, the Master Servicer or the applicable Servicer, as the case may be, hereunder, without the execution or filing of any paper or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding; provided, however, that the successor or surviving Person to the applicable Servicer shall be qualified to service mortgage loans on behalf of FNMA or FHLMC.

Section 7.03 Limitation on Liability of the Depositor, the Master Servicer, the Servicers and Others; Liability of Master Servicer and Servicers.

(a) None of the Depositor, the Master Servicer, either Servicer or any of the directors, officers, employees or agents of the Depositor, the Master Servicer or of a Servicer shall be under any liability to the Trust Estate or the Certificateholders for any action taken or for refraining from the taking of any action in good faith pursuant to this Agreement, or for errors in judgment; provided, however, that this provision shall not protect the Depositor, the Master Servicer, the Servicers or any such Person against any breach of warranties or representations made herein or any liability which would otherwise be imposed by reason of willful misfeasance, bad faith or gross negligence in the performance of duties or by reason of reckless disregard of obligations and duties hereunder. The Depositor, the Master Servicer, each Servicer and any director, officer, employee or agent of the Depositor, the Master Servicer or a Servicer may rely in good faith on any document of any kind prima facie properly executed and submitted by any Person respecting any matters arising hereunder. The Depositor, the Master Servicer, each

Servicer and any director, officer, employee or agent of the Depositor, the Master Servicer or a Servicer shall be indemnified by the Trust Estate and held harmless against any loss, liability or expense incurred in connection with any legal action relating to this Agreement or the Certificates, other than any loss, liability or expense related to any specific Mortgage Loan or Mortgage Loans (except as any such loss, liability or expense shall be otherwise reimbursable pursuant to this Agreement) and any loss, liability or expense incurred by reason of willful misfeasance, bad faith or gross negligence in the performance of duties hereunder or by reason of reckless disregard of obligations and duties hereunder. None of the Depositor, the Master Servicer or either Servicer shall be under any obligation to appear in, prosecute or defend any legal action which is not incidental to its respective duties under this Agreement and which in its opinion may involve it in any expense or liability; provided, however, that the Depositor, the Master Servicer or a Servicer may in its discretion undertake any such action which it may deem necessary or desirable in respect to this Agreement and the rights and duties of the parties hereto and the interests of the Certificateholders hereunder. In such event, the legal expenses and costs of such action and any liability resulting therefrom shall be expenses, costs and liabilities of the Trust Estate, and the Depositor, the Master Servicer and each Servicer shall be entitled to be reimbursed therefor out of amounts attributable to the Mortgage Loans on deposit in the related Servicer Custodial Account as provided by Section 3.11.

(b) Subject to clause (a) above, each Servicer (except the Trustee if it is required to succeed the Servicer hereunder) indemnifies and holds the Trustee, the Master Servicer, the Certificate Administrator, the Depositor and the Trust harmless against any and all claims, losses, penalties, fines, forfeitures, reasonable legal fees and related costs, judgments, and any other costs, fees and expenses that the Trustee, the Master Servicer, the Certificate Administrator, the Depositor and the Trust may sustain in any way related to the failure of such Servicer to perform its duties and service the Mortgage Loans in compliance with this Agreement. The related Servicer, the Trustee, the Master Servicer, the Certificate Administrator and the Depositor shall notify the other parties if a claim is made that may result in such claims, losses, penalties, fines, forfeitures, legal fees or related costs, judgments, or any other costs, fees and expenses, and the related Servicer shall assume (with the consent of the Trustee and the Depositor) the defense of any such claim and pay all expenses in connection therewith, including reasonable counsel fees, and promptly pay, discharge and satisfy any judgment or decree which may be entered against any Servicer, the Trustee, the Master Servicer, the Certificate Administrator, the Depositor or the Trust in respect of such claim. The provisions of this Section 7.03(b) shall survive the resignation or removal of any Servicer, the termination of this Agreement and the payment of the outstanding Certificates.

(c) In taking or recommending any course of action pursuant to this Agreement, unless specifically required to do so pursuant to this Agreement, a Servicer shall not be required to investigate or make recommendations concerning potential liabilities which the Trust might incur as a result of such course of action by reason of the condition of the Mortgaged Properties but shall give notice to the Trustee and the Certificate Administrator if it has notice of such potential liabilities.

(d) A Servicer shall not be liable for any acts or omissions of any other Servicer, except as otherwise expressly provided herein.

(e) Subject to clause (a) above, the Master Servicer indemnifies and holds the Trustee, the Certificate Administrator, the Depositor and the Trust harmless against any and all claims, losses, penalties, fines, forfeitures, reasonable legal fees and related costs, judgments, and any other costs, fees and expenses that the Trustee, the Certificate Administrator, the Depositor and the Trust may sustain related to the failure of the Master Servicer to perform its duties and master service the Mortgage Loans in compliance with this Agreement. The Master Servicer, the Trustee, the Certificate Administrator and the Depositor shall notify the other parties if a claim is made that may result in such claims, losses, penalties, fines, forfeitures, legal fees or related costs, judgments, or any other costs, fees and expenses, and the Master Servicer shall assume (with the consent of the Trustee and the Depositor) the defense of any such claim and pay all expenses in connection therewith, including reasonable counsel fees, and promptly pay, discharge and satisfy any judgment or decree which may be entered against the Trustee, the Master Servicer, the Certificate Administrator, the Depositor or the Trust in respect of such claim. The provisions of this Section 7.03(e) shall survive the resignation or removal of the Master Servicer, the termination of this Agreement and the payment of the outstanding Certificates.

(f) The Master Servicer shall not be under any obligation to appear in, prosecute or defend any legal action that is not incidental to its duties under this Agreement and that in its opinion may involve it in any expense or liability; provided, however, the Master Servicer may in its discretion, with the consent of the Trustee (which consent shall not be unreasonably withheld), undertake any such action which it may deem necessary or desirable with respect to this Agreement and the rights and duties of the parties hereto and the interests of the Certificateholders hereunder. In such event, the legal expenses and costs of such action and any liability resulting therefrom shall be expenses, costs and liabilities of the Trust, and the Master Servicer shall be entitled to be reimbursed therefor out of the Collection Account as provided by Section 3.11(b) hereof. Nothing in this Section 7.03(f) shall affect the Master Servicer’s obligation to supervise, or to take such actions as are necessary to ensure, the servicing and administration of the Mortgage Loans pursuant to Sections 3.24 and 3.25 hereof.

Section 7.04 Depositor, Master Servicer and Servicers Not to Resign. Subject to the provisions of Section 7.02, none of the Depositor, the Master Servicer or any Servicer shall resign from its respective obligations and duties hereby imposed on it except upon determination that its duties hereunder are no longer permissible under applicable law. Any such determination permitting the resignation of the Depositor, the Master Servicer or a Servicer shall be evidenced by an Opinion of Counsel to such effect delivered to the Trustee and the Certificate Administrator. No such resignation by a Servicer shall become effective until the Master Servicer or a successor Servicer shall have assumed such Servicer’s responsibilities and obligations in accordance with Section 8.05 hereof, and no such resignation by the Master Servicer shall become effective unless and until the Certificate Administrator shall also resign and be removed in accordance with Section 9.06 hereof.

Section 7.05 Successor Master Servicer. If the Master Servicer shall for any reason no longer be the Master Servicer (including by reason of an Event of Default), the Trustee shall thereupon assume, if it so elects, or shall appoint a successor Master Servicer to assume, all of the rights and obligations of such Master Servicer hereunder arising thereafter (except that the Trustee or any successor Master Servicer shall not be (a) liable for any acts or omissions of such

predecessor Master Servicer hereunder, (b) obligated to make Advances if it is prohibited from doing so by applicable law, (c) deemed to have made any representations or warranties of such predecessor Master Servicer hereunder, (d) fund any losses on any Permitted Investment directed by such predecessor Master Servicer, or (e) obligated to perform any obligation of the Master Servicer under Section 12.06 or Section 12.08 with respect to any period of time during which the Trustee or such successor Master Servicer was not acting as the Master Servicer). Any such assumption shall be subject to Section 8.05 hereof and shall require the removal of the Certificate Administrator in accordance with Section 9.06 hereof.

In connection with the appointment of any successor master servicer or the assumption of the duties of the Master Servicer, the Trustee may make such arrangements for the compensation of such successor master servicer out of payments on the Mortgage Loans as the Trustee and such successor master servicer shall agree. Notwithstanding the foregoing, the compensation payable to a successor master servicer may not exceed the compensation which the Master Servicer would have been entitled to retain if the Master Servicer had continued to act as Master Servicer hereunder.

All costs incurred in connection with the transition of the master servicing to the Trustee or the successor Master Servicer shall be paid by the predecessor Master Servicer, and if not so paid shall be reimbursed to the Trustee by the Trust. If the Trustee is acting as Master Servicer pursuant to either Section 7.04 or Section 8.05, all costs incurred by the Trustee acting as Master Servicer in connection with the transition of master servicing from the Trustee to a successor Master Servicer shall be paid by the predecessor Master Servicer from which the Trustee took over as Master Servicer pursuant to either Section 7.04 or Section 8.05, and if not so paid shall be reimbursed to the Trustee by the Trust.

Section 7.06 Sale and Assignment of Master Servicing. The Master Servicer may sell and assign its rights and delegate its duties and obligations in its entirety as Master Servicer under this Agreement and the Depositor may terminate the Master Servicer without cause and select a new Master Servicer; provided, however, that: (i) the purchaser or transferee accepting such assignment and delegation (a) shall be a Person which shall be qualified to service mortgage loans for Fannie Mae or Freddie Mac; (b) shall have a net worth of not less than $10,000,000 (unless otherwise approved by each Rating Agency pursuant to clause (ii) below); (c) shall be reasonably satisfactory to the Trustee and the Depositor (as evidenced in a writing signed by the Trustee and the Depositor); and (d) shall execute and deliver to the Trustee an agreement, in form and substance reasonably satisfactory to the Trustee, which contains an assumption by such Person of the due and punctual performance and observance of each covenant and condition to be performed or observed by it as master servicer under this Agreement and any custodial agreement from and after the effective date of such agreement; (ii) each Rating Agency shall be given prior written notice of the identity of the proposed successor to the Master Servicer, and each Rating Agency’s rating of the Certificates in effect immediately prior to such assignment, sale and delegation will not be downgraded, qualified or withdrawn as a result of such assignment, sale and delegation, as evidenced by a letter to such effect delivered to the Master Servicer and the Trustee; (iii) the Master Servicer assigning and selling the master servicing shall deliver to the Trustee an Officer’s Certificate and an Opinion of Counsel addressed to the Trustee, each stating that all conditions precedent to such action under this Agreement have been completed and such action is permitted by and complies with the terms of

this Agreement; (iv) in the event the Master Servicer is terminated without cause by the Depositor, the Depositor shall pay the terminated Master Servicer a termination fee equal to 0.25% of the aggregate Stated Principal Balance of the Mortgage Loans at the time the master servicing of the Mortgage Loans is transferred to the successor Master Servicer; and (v) the Certificate Administrator shall also resign and be removed in accordance with Section 9.06 hereof. No such assignment or delegation shall affect any rights or liabilities of the Master Servicer arising prior to the effective date thereof.

ARTICLE VIII

DEFAULT

Section 8.01 Events of Default. If any one of the following events (“Events of Default”) shall occur and be continuing:

(a) any failure by the Master Servicer or a Servicer to deposit amounts in the Certificate Account, Collection Account or the related Servicer Custodial Account, respectively, in the amount and manner provided herein so as to enable the Certificate Administrator to distribute to Holders of Certificates any payment required to be made under the terms of such Certificates and this Agreement which continues unremedied for a period of one day after the date upon which written notice of such failure shall have been given to the Master Servicer or such Servicer; or

(b) failure on the part of the Master Servicer or a Servicer duly to observe or perform in any material respect any other covenants or agreements of the Master Servicer or such Servicer set forth in the Certificates or in this Agreement, which covenants and agreements continue unremedied for a period of 30 days after the date on which written notice of such failure, requiring the same to be remedied, shall have been given to the Master Servicer or such Servicer by the Certificate Administrator, the Trustee or the Depositor, or to the Master Servicer, the Servicers, the Depositor, the Certificate Administrator and the Trustee by the Holders of Certificates evidencing Voting Rights aggregating not less than 25% of all Certificates affected thereby; or

(c) any breach of a representation or warranty made by a Servicer or the Master Servicer under this Agreement, which materially and adversely affects the interests of the Certificateholders, and which breach continues unremedied for a period of 30 days after the date on which written notice of such breach, requiring the same to be remedied, shall have been given to such Servicer by the Master Servicer, the Certificate Administrator, the Trustee or the Depositor, or to the Servicers, the Master Servicer, the Depositor, the Certificate Administrator and the Trustee by the Holders of Certificates evidencing Voting Rights aggregating not less than 25% of all Certificates affected thereby; or

(d) the entry of a decree or order by a court or agency or supervisory authority having jurisdiction in the premises for the appointment of a conservator, receiver or liquidator in any insolvency, readjustment of debt, marshalling of assets and liabilities or similar proceedings against the Master Servicer or a Servicer, or for the winding up or liquidation of the Master

Servicer or a Servicer’s affairs, and the continuance of any such decree or order unstayed and in effect for a period of 60 consecutive days; or

(e) the consent by the Master Servicer or a Servicer to the appointment of a conservator or receiver or liquidator in any insolvency, readjustment of debt, marshalling of assets and liabilities or similar proceedings of or relating to the Master Servicer or a Servicer or of or relating to substantially all of its property; or the Master Servicer or a Servicer shall admit in writing its inability to pay its debts generally as they become due, file a petition to take advantage of any applicable insolvency or reorganization statute, make an assignment for the benefit of its creditors, or voluntarily suspend payment of its obligations; or

(f) the failure by the Master Servicer or a Servicer to duly perform, within the required time period, its obligations under Article XII;

then, and in each and every such case (other than an Event of Default described in clause (a) hereof regarding a failure to make required Periodic Advances), (i) so long as an Event of Default in respect of a Servicer shall not have been remedied by the applicable Servicer, the Master Servicer may, and at the direction of the Holders of Certificates evidencing Voting Rights aggregating not less than 51% of all Certificates affected thereby shall, by notice then given in writing to such Servicer, terminate all of the rights and obligations of such Servicer under this Agreement and (ii) so long as an Event of Default in respect of the Master Servicer shall not have been remedied by the Master Servicer, either the Trustee or the Depositor may, and at the direction of the Holders of Certificates evidencing Voting Rights aggregating not less than 51% of all Certificates affected thereby shall, by notice then given in writing to the Master Servicer (and to the Trustee, if given by the Depositor, and to the Depositor, if given by the Trustee), terminate all of the rights and obligations of the Master Servicer under this Agreement. If an Event of Default described in clause (a) hereof regarding a failure to make required Periodic Advances shall occur in respect of a Servicer, the Master Servicer shall, by notice to the related Servicer, terminate all of the rights and obligations of such Servicer under this Agreement and the Master Servicer, as successor Servicer, or another successor Servicer appointed by the Master Servicer pursuant to Section 8.05, shall make the Periodic Advance which such Servicer failed to make (subject to the Master Servicer’s determination as to the recoverability of such Periodic Advance). If an Event of Default described in clause (a) hereof regarding a failure to make required Periodic Advances shall occur in respect of the Master Servicer, the Trustee shall, by notice to the Master Servicer, terminate all of the rights and obligations of the Master Servicer under this Agreement and the Trustee, as successor Servicer, or another successor Servicer appointed by the Trustee, acting as successor Master Servicer, pursuant to Section 8.05, shall make the Periodic Advance which the Master Servicer failed to make. Any Event of Default described in this Section 8.01 in respect of the Master Servicer shall include and refer to the Master Servicer acting as Master Servicer and as Certificate Administrator.

On or after the receipt by a Servicer of a written notice of termination pursuant to this Section 8.01, all authority and power of such Servicer under this Agreement, whether with respect to the Certificates or the Mortgage Loans or otherwise, shall pass to and be vested in the Master Servicer (or in the successor Servicer appointed by the Depositor, for any Event of Default pursuant to Section 8.01(f)), subject to Sections 3.25 and 8.05 hereof, pursuant to and under this Section 8.01, unless and until such time as the Master Servicer, if applicable, shall

appoint a successor Servicer pursuant to Section 8.05, and, without limitation, the Master Servicer (or the successor Servicer appointed by the Depositor, as the case may be) is hereby authorized and empowered to execute and deliver, on behalf of such Servicer, as attorney-in-fact or otherwise, any and all documents and other instruments, and to do or accomplish all other acts or things necessary or appropriate to effect the purposes of such notice of termination. Each Servicer agrees to cooperate with the Master Servicer (or the successor Servicer appointed by the Depositor, as the case may be) in effecting the termination of the responsibilities and rights of such Servicer hereunder, including, without limitation, the transfer to the Master Servicer (or the successor Servicer appointed by the Depositor, as the case may be), for the administration by it, of all amounts that have been deposited by such Servicer in the related Servicer Custodial Account or thereafter received by such Servicer with respect to the Mortgage Loans.

The Master Servicer (or the successor Servicer appointed by the Depositor, as the case may be) shall be entitled to be reimbursed by the Servicer (or by the Trust, if the Servicer is unable to fulfill its obligations hereunder) for all costs associated with the transfer of servicing, including, without limitation, any costs or expenses associated with the complete transfer of all servicing data and the completion, correction or manipulation of such servicing data as may be required by the Master Servicer (or the successor Servicer appointed by the Depositor, as the case may be) to correct any errors or insufficiencies in the servicing data or otherwise to enable the Master Servicer (or the successor Servicer appointed by the Depositor, as the case may be) to service the Mortgage Loans properly and effectively.

If the Master Servicer acts as a successor Servicer, it shall not assume liability for the representations and warranties of the Servicer that it replaces. The Master Servicer shall use reasonable efforts to have any successor Servicer assume liability for the representations and warranties made by the terminated Servicer, and, in the event of any such assumption by the successor Servicer, the Master Servicer may, in the exercise of its business judgment, release the terminated Servicer from liability for such representations and warranties.

On or after the receipt by the Master Servicer of a written notice of termination pursuant to this Section 8.01, all authority and power of the Master Servicer and Certificate Administrator under this Agreement, whether with respect to the Certificates or the Mortgage Loans or otherwise, shall pass to and be vested in the Trustee (or in the successor Master Servicer appointed by the Depositor, for any Event of Default pursuant to Section 8.01(f)), subject to Section 8.05 hereof, pursuant to and under this Section 8.01, unless and until such time as the Trustee shall appoint a successor Master Servicer and Certificate Administrator pursuant to Section 8.05, and, without limitation, the Trustee (or the successor Master Servicer appointed by the Depositor, as the case may be) is hereby authorized and empowered to execute and deliver, on behalf of the Master Servicer and Certificate Administrator, as attorney-in-fact or otherwise, any and all documents and other instruments, and to do or accomplish all other acts or things necessary or appropriate to effect the purposes of such notice of termination. The Master Servicer and Certificate Administrator agree to cooperate with the Trustee (or the successor Master Servicer appointed by the Depositor, as the case may be) in effecting the termination of the responsibilities and rights of the Master Servicer and Certificate Administrator hereunder, including, without limitation, the transfer to the Trustee (or the successor Master Servicer appointed by the Depositor, as the case may be), for the administration by it, of all amounts that have been deposited by the Master Servicer or Certificate Administrator in the Collection

Account or the Certificate Account or thereafter received by the Master Servicer or Certificate Administrator with respect to the Mortgage Loans.

Upon obtaining notice or knowledge of the occurrence of any Event of Default, the Person obtaining such notice or knowledge shall give prompt written notice thereof to Certificateholders at their respective addresses appearing in the Certificate Register and to each Rating Agency. All costs and expenses (including attorneys’ fees) incurred in connection with transferring the servicing files to the successor Servicer and amending this Agreement to reflect such succession as Servicer pursuant to this Section 8.01 shall be paid by the predecessor Servicer (or, if the predecessor Servicer is the Master Servicer, by the predecessor to such predecessor, or, if not so paid, by the Trust). All costs and expenses (including attorneys’ fees) incurred in connection with transferring the master servicing files to the successor Master Servicer and amending this Agreement to reflect such succession as Master Servicer pursuant to this Section 8.01 shall be paid by the predecessor Master Servicer (or, if the predecessor Master Servicer is the Trustee, by the predecessor to such predecessor, or, if not so paid, by the Trust). Notwithstanding the termination of the Master Servicer or any Servicer pursuant hereto, the Master Servicer and each Servicer shall remain liable for any causes of action arising out of any Event of Default relating to the Master Servicer or such Servicer, respectively, occurring prior to such termination.

The Master Servicer may waive any Event of Default with respect to a Servicer, and the Holders of Certificates entitled to at least 66 2/3% of the Voting Rights allocated to the Classes of Certificates affected by an Event of Default may, on behalf of all Certificateholders, waive any events permitting removal of the Master Servicer as the Master Servicer or a Servicer as servicer pursuant to this Article VIII, provided, however, that an Event of Default involving making a required distribution on a Certificate may only be waived by all Holders of Certificates, provided further, however, that any Event of Default under Section 8.01(f) may only be waived with the consent of the Depositor. Upon any waiver of a past default, such default shall cease to exist and any Event of Default arising therefrom shall be deemed to have been remedied for every purpose of this Agreement. No such waiver shall extend to any subsequent or other default or impair any right consequent thereto except to the extent expressly so waived. Notice of any such waiver shall be given by the Certificate Administrator to the Rating Agencies.

Section 8.02 Remedies of Trustee. During the continuance of any Event of Default, so long as such Event of Default shall not have been remedied, the Trustee, in addition to the rights specified in Section 8.01, shall have the right, in its own name as trustee of an express trust, to take all actions now or hereafter existing at law, in equity or by statute to enforce its rights and remedies and to protect the interests, and enforce the rights and remedies, of the Certificateholders (including the institution and prosecution of all judicial, administrative and other proceedings and the filing of proofs of claim in connection therewith). Except as otherwise expressly provided in this Agreement, no remedy provided for by this Agreement shall be exclusive of any other remedy, and each and every remedy shall be cumulative and in addition to any other remedy and no delay or omission to exercise any right or remedy shall impair any such right or remedy or shall be deemed to be a waiver of any Event of Default.

Section 8.03 Directions by Certificateholders and Duties of Trustee During Event of Default. During the continuance of any Event of Default, Holders of Certificates

100

evidencing Voting Rights aggregating not less than 25% of each Class of Certificates affected thereby may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee under this Agreement; provided, however, that the Trustee shall be under no obligation to pursue any such remedy, or to exercise any of the trusts or powers vested in it by this Agreement (including, without limitation, (a) the conducting or defending of any administrative action or litigation hereunder or in relation hereto, and (b) the terminating of the Master Servicer or any successor Master Servicer from its rights and duties as servicer hereunder) at the request, order or direction of any of the Certificateholders, unless such Certificateholders shall have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities which may be incurred therein or thereby and, provided further, that, subject to the provisions of Section 9.01, the Trustee shall have the right to decline to follow any such direction if the Trustee, based upon an Opinion of Counsel, determines that the action or proceeding so directed may not lawfully be taken or if the Trustee in good faith determines that the action or proceeding so directed would involve it in personal liability or be unjustly prejudicial to the non-assenting Certificateholders.

Section 8.04 Action upon Certain Failures of the Master Servicer or a Servicer and upon Event of Default. In the event that a Responsible Officer of the Certificate Administrator or the Trustee shall have actual knowledge of any failure of the Master Servicer or a Servicer specified in Section 8.01(a) or (b) which would become an Event of Default upon the Master Servicer’s or such Servicer’s failure to remedy the same after notice, the Certificate Administrator or the Trustee, as the case may be, shall give notice thereof to the Master Servicer or such Servicer, as applicable. If a Responsible Officer of the Certificate Administrator or the Trustee shall have knowledge of an Event of Default, the Certificate Administrator or the Trustee, as the case may be, shall give prompt written notice thereof to the Certificateholders.

Section 8.05

Trustee and Master Servicer to Act; Appointment of Successors.

(a) If an Event of Default (other than an Event of Default pursuant to Section 8.01(f)) occurs with respect to the Master Servicer, the Trustee shall take action as follows:

(i) On and after the time the Master Servicer receives a notice of termination pursuant to Section 8.01, the Trustee shall, subject to the provisions of Section 7.05 hereof, be the successor in all respects to the Master Servicer in its capacity as master servicer under this Agreement and the transactions set forth or provided for herein and shall be subject to all the responsibilities, duties and liabilities relating thereto placed on the Master Servicer by the terms and provisions hereof or shall appoint a successor pursuant to Section 7.05. Notwithstanding anything provided herein to the contrary, under no circumstances shall any provision of this Agreement be construed to require the Trustee, acting in its capacity as successor to the Master Servicer in its obligation to make Advances, to advance, expend or risk its own funds or otherwise incur any financial liability in the performance of its duties hereunder if it shall have reasonable grounds for believing that such funds are non-recoverable. Notwithstanding the above, the Trustee may, if it shall be unwilling so to act, or shall, if it is legally unable so to act, appoint, or petition a court of competent jurisdiction to appoint, any established housing and home finance institution having a net worth of not less than $15,000,000 as the successor to the terminated Master Servicer hereunder in the assumption of all or any part

101

of the responsibilities, duties or liabilities of the Master Servicer hereunder; provided, however, that any such institution appointed as successor Master Servicer shall not, as evidenced in writing by each Rating Agency, adversely affect the then current rating of any Class of Certificates immediately prior to the termination of the terminated Master Servicer. The appointment of the Trustee or any other successor Master Servicer shall not affect any liability of the predecessor Master Servicer which may have arisen under this Agreement prior to its termination as Master Servicer, nor shall the Trustee or any other successor Master Servicer be liable for any acts or omissions of the predecessor Master Servicer or for any breach by such predecessor Master Servicer of any of its representations or warranties contained herein or in any related document or agreement. Pending appointment of a successor to the terminated Master Servicer hereunder, unless the Trustee is prohibited by law from so acting, the Trustee shall act in such capacity as provided above. The Trustee and such successor shall take such action, consistent with this Agreement, as shall be necessary to effectuate any such succession.

(b) If an Event of Default (other than an Event of Default pursuant to Section 8.01(f)) occurs with respect to a Servicer, the Master Servicer shall take action as follows:

(i) On and after the time a Servicer receives a notice of termination pursuant to Section 8.01, the Master Servicer shall, subject to the provisions of Section 3.25 hereof, be the successor in all respects to such Servicer in its capacity as servicer under this Agreement and the transactions set forth or provided for herein and shall be subject to all the responsibilities, duties and liabilities relating thereto placed on such Servicer by the terms and provisions hereof or shall appoint a successor pursuant to Section 3.25. Notwithstanding anything provided herein to the contrary, under no circumstances shall any provision of this Agreement be construed to require the Master Servicer, acting in its capacity as successor to a Servicer in its obligation to make Advances, to advance, expend or risk its own funds or otherwise incur any financial liability in the performance of its duties hereunder if it shall have reasonable grounds for believing that such funds are non-recoverable. Subject to Section 8.05(b)(ii), as compensation therefor, the Master Servicer shall be entitled to such compensation as the terminated Servicer would have been entitled to hereunder if no such notice of termination had been given. Notwithstanding the above, the Master Servicer may, if it shall be unwilling so to act, or shall, if it is legally unable so to act, appoint, or petition a court of competent jurisdiction to appoint, any established housing and home finance institution having a net worth of not less than $15,000,000 as the successor to the terminated Servicer hereunder in the assumption of all or any part of the responsibilities, duties or liabilities of such Servicer hereunder; provided, however, that any such institution appointed as successor Servicer shall not, as evidenced in writing by each Rating Agency, adversely affect the then current rating of any Class of Certificates immediately prior to the termination of the terminated Servicer. The appointment of the Master Servicer or any other successor Servicer shall not affect any liability of the predecessor Servicer which may have arisen under this Agreement prior to its termination as a Servicer, nor shall the Master Servicer or any other successor Servicer be liable for any acts or omissions of the predecessor Servicer or for any breach by such predecessor Servicer of any of its representations or warranties contained herein or in any related document or agreement. Pending appointment of a successor to the terminated Servicer

102

hereunder, unless the Master Servicer is prohibited by law from so acting, the Master Servicer shall act in such capacity as provided above. The Master Servicer and such successor shall take such action, consistent with this Agreement, as shall be necessary to effectuate any such succession.

(ii) In connection with the appointment of a successor Servicer or the assumption of the duties of a Servicer, as specified in Section 8.05(b)(i), the Master Servicer may make such arrangements for the compensation of such successor out of payments on Mortgage Loans serviced by the predecessor Servicer as it and such successor shall agree, not to exceed the Servicing Fee Rate.

(c) If an Event of Default pursuant to Section 8.01(f) occurs with respect to a Servicer or the Master Servicer, on and after the time such Servicer or the Master Servicer receives a notice of termination pursuant to Section 8.01, the successor to such Servicer or the Master Servicer appointed by the Depositor shall be the successor in all respects to such Servicer or the Master Servicer under this Agreement and the transactions set forth or provided for herein and shall be subject to all the responsibilities, duties and liabilities relating thereto placed on such Servicer or the Master Servicer by the terms and provisions hereof. The successor to such Servicer or Master Servicer shall be an established housing and home finance institution having a net worth of not less than $15,000,000; provided, however, that any such institution appointed as successor Servicer or Master Servicer shall not, as evidenced in writing by each Rating Agency, adversely affect the then current rating of any Class of Certificates immediately prior to the termination of the terminated Servicer or Master Servicer, as applicable. The appointment of the successor Servicer or Master Servicer shall not affect any liability of the predecessor Servicer or Master Servicer, as applicable, which may have arisen under this Agreement prior to its termination as a Servicer or Master Servicer, nor shall the successor Servicer or Master Servicer be liable for any acts or omissions of the predecessor Servicer or Master Servicer, as applicable, or for any breach by such predecessor Servicer or Master Servicer of any of its representations or warranties contained herein or in any related document or agreement. Any such successor Servicer or Master Servicer shall take such action, consistent with this Agreement, as shall be necessary to effectuate any such succession. In connection with the appointment of a successor Servicer or the assumption of the duties of a Servicer, the Master Servicer may make such arrangements for the compensation of such successor out of payments on Mortgage Loans serviced by the predecessor Servicer as it and such successor shall agree, not to exceed the Servicing Fee Rate.

Section 8.06 Notification to Certificateholders. Upon any termination or appointment of a successor to the Master Servicer or a Servicer pursuant to this Article VIII, the Certificate Administrator shall give prompt written notice thereof to Certificateholders at their respective addresses appearing in the Certificate Register and to the Rating Agencies.

ARTICLE IX

THE TRUSTEE AND CERTIFICATE ADMINISTRATOR

Section 9.01 Duties of Trustee and the Certificate Administrator.

(a) The Trustee prior to the occurrence of an Event of Default with respect to the Master Servicer and after the curing or waiver of all Events of Default with respect to the Master Servicer which may have occurred, undertakes to perform such duties and only such duties as are specifically set forth in this Agreement. In case an Event of Default with respect to the Master Servicer has occurred of which a Responsible Officer of the Trustee shall have actual knowledge (which has not been cured or waived), the Trustee shall exercise such of the rights and powers vested in it by this Agreement, and use the same degree of care and skill in their exercise as a reasonably prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs. The Certificate Administrator shall perform such duties and only such duties as are specifically required of it, as set forth in this Agreement.

The Trustee and the Certificate Administrator, upon receipt of all resolutions, certificates, statements, opinions, reports, documents, orders or other instruments furnished to the Trustee and the Certificate Administrator which are specifically required to be furnished pursuant to any provision of this Agreement, shall examine them to determine whether they conform to the requirements of this Agreement; provided however that neither the Trustee nor the Certificate Administrator shall be responsible for the accuracy or content of any resolution, certificate, statement, opinion, report, document, order or other instrument furnished by the Servicers or the Depositor hereunder. If any such instrument is found not to conform in any material respect to the requirements of this Agreement, the Trustee or the Certificate Administrator, as the case may be, shall notify the Certificateholders of such instrument in the event that the Trustee or the Certificate Administrator, as the case may be, after so requesting, does not receive a satisfactorily corrected instrument.

(b) No provision of this Agreement shall be construed to relieve the Trustee or the Certificate Administrator from liability for its own negligent action, its own negligent failure to act or its own willful misfeasance; provided, however, that:

(i) Prior to the occurrence of an Event of Default with respect to the Master Servicer of which a Responsible Officer of the Trustee shall have actual knowledge, and after the curing or waiver of all such Events of Default with respect to the Master Servicer which may have occurred, the duties and obligations of the Trustee shall be determined solely by the express provisions of this Agreement; neither the Trustee nor the Certificate Administrator shall be liable except for the performance of such duties and obligations as are specifically set forth in this Agreement, no implied covenants or obligations shall be read into this Agreement against the Trustee or the Certificate Administrator and, in the absence of bad faith on the part of the Trustee and the Certificate Administrator, the Trustee and the Certificate Administrator may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee and the Certificate

104

Administrator by the Depositor, the Master Servicer or any Servicer and which on their face, do not contradict the requirements of this Agreement;

(ii) Neither the Trustee (in its individual capacity) nor the Certificate Administrator (in its individual capacity) shall be personally liable for an error of judgment made in good faith by any Responsible Officer or other officers thereof, unless it shall be proved that the Trustee or the Certificate Administrator, as the case may be, was negligent in ascertaining the pertinent facts;

(iii) Neither the Trustee (in its individual capacity) nor the Certificate Administrator (in its individual capacity) shall be personally liable with respect to any action taken, suffered or omitted to be taken by it in good faith in accordance with the direction of Certificateholders as provided in Section 8.03;

(iv) The Trustee shall not be charged with knowledge of any default or Event of Default unless a Responsible Officer of the Trustee assigned to and working in the Corporate Trust Office obtains actual knowledge of such default or Event of Default or any officer of the Trustee receives written notice of such default or Event of Default at its Corporate Trust Office. In the absence of such notice or actual knowledge, the Trustee may conclusively assume that there is no default or Event of Default; and

(v) The Certificate Administrator shall not be charged with knowledge of any default (other than a default in payment to the Certificate Administrator) unless a Responsible Officer of the Certificate Administrator assigned to working in the Corporate Trust Office obtains actual knowledge of such failure or event or any officer of the Certificate Administrator receives written notice of such failure or event at its Corporate Trust Office and in the absence of receipt of such notice or actual knowledge, the Certificate Administrator may conclusively assume that there is no default or Event of Default;

(vi) No provision in this Agreement shall require the Trustee or the Certificate Administrator to expend or risk its own funds (including, without limitation, the making of any Advance by the Trustee as a successor Master Servicer) or otherwise incur any personal financial liability in the performance of any of its duties as Trustee or Certificate Administrator hereunder, or in the exercise of any of its rights or powers, if the Trustee or the Certificate Administrator shall have reasonable grounds for believing that repayment of funds or adequate indemnity against such risk or liability is not reasonably assured to it, and none of the provisions contained in this Agreement shall in any event require the Trustee or the Certificate Administrator to perform, or be responsible for the manner or performance of, any of the obligations of a Servicer under this Agreement, except, with respect to the Master Servicer, during such time, if any, as the Master Servicer shall be the successor to, and be vested with the rights, duties, powers and privileges of, a predecessor Servicer in accordance with the terms of this Agreement; and

(vii) Neither the Certificate Administrator nor the Trustee shall have a duty (A) to see to any recording, filing, or depositing of this Agreement or any agreement referred to herein or any financing statement or continuation statement, or to see to the

105

maintenance of any such recording or filing or depositing or to any rerecording, refiling or redepositing of any thereof, (B) to see to any insurance, or (C) to see to the payment or discharge or any tax, assessment, or other governmental charge or any lien or encumbrance of any kind owing with respect to, assessed or levied against, any part of the Trust Estate other than from funds available in the Certificate Account.

106

Holders of Certificates of any Class evidencing, as to such Class, Percentage Interests aggregating not less than 50%; provided, however, that if the payment within a reasonable time to the Trustee of the costs, expenses or liabilities likely to be incurred by it in the making of such investigation is, in the opinion of the Trustee, not reasonably assured to the Trustee by the security afforded to it by the terms of this Agreement, the Trustee may require reasonable indemnity against such expense or liability or payment of such estimated expenses as a condition to so proceeding;

(vi) Prior to the occurrence of an Event of Default hereunder and after the curing or waiving of all Events of Default which may have occurred, the Certificate Administrator shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, approval, bond or other paper or document, unless requested in writing so to do by Holders of Certificates of any Class evidencing, as to such Class, Percentage Interests aggregating not less than 50%; provided, however, that if the payment within a reasonable time to the Certificate Administrator of the costs, expenses or liabilities likely to be incurred by it in the making of such investigation is, in the opinion of the Certificate Administrator, not reasonably assured to the Certificate Administrator by the security afforded to it by the terms of this Agreement, the Certificate Administrator may require reasonable indemnity against such expense or liability or payment of such estimated expenses as a condition to so proceeding; and

(vii) The right of the Trustee and the Certificate Administrator to perform any discretionary act enumerated in this Agreement shall not be construed as a duty, and neither the Certificate Administrator nor the Trustee shall be answerable for other than it negligence or willful misconduct in the performance of such act;

Section 9.03 Neither Trustee nor Certificate Administrator Liable for Certificates or Mortgage Loans. The recitals contained herein and in the Certificates (other than the execution of, and the authentication of, the Certificates by the Trustee) shall not be taken as the statements of the Trustee or the Certificate Administrator, and neither the Trustee nor the Certificate Administrator assumes responsibility for their correctness. Neither the Trustee nor the Certificate Administrator makes any representations as to the validity or sufficiency of this Agreement or of the Certificates or any Mortgage Loans save that the Trustee and the Certificate Administrator represent that, assuming due execution and delivery by the other parties hereto, this Agreement has been duly authorized, executed and delivered by it and constitutes its legal,

107

valid and binding obligation, enforceable against it in accordance with its terms, subject to applicable insolvency, receivership, moratorium and other laws affecting the rights of creditors generally, and to general principles of equity and the discretion of the court (regardless of whether considered in a proceeding in equity or at law). Neither the Trustee nor the Certificate Administrator shall be accountable for the use or application by the Depositor of funds paid to the Depositor in consideration of the assignment of the Mortgage Loans hereunder by the Depositor, or for the use or application of any funds paid to Subservicers or any Servicer in respect of the Mortgage Loans or deposited into a Servicer Custodial Account, the Collection Account or any other account hereunder (other than the Certificate Account) by the Master Servicer or a Servicer.

Neither the Trustee nor the Certificate Administrator shall at any time have any responsibility or liability for or with respect to the legality, validity and enforceability of any Mortgage or any Mortgage Loan, or the perfection and priority of any Mortgage or the maintenance of any such perfection and priority or for or with respect to the sufficiency of the Trust Estate or its ability to generate the payments to be distributed to Certificateholders under this Agreement, including, without limitation: the existence, condition and ownership of any Mortgaged Property; the existence and enforceability of any hazard insurance thereon (other than if the Trustee shall assume the duties of a predecessor Master Servicer pursuant to Section 8.05 and thereupon only for the acts or omissions of the Trustee as successor Master Servicer); the validity of the assignment of any Mortgage Loan to the Trustee or of any intervening assignment; the completeness of any Mortgage Loan; the performance or enforcement of any Mortgage Loan (other than if the Trustee shall assume the duties of a predecessor Master Servicer pursuant to Section 8.05 and thereupon only for the acts or omissions of the Trustee as successor Master Servicer); the compliance by the Depositor, the Master Servicer or the Servicers with any warranty or representation made under this Agreement or in any related document or the accuracy of any such warranty or representation; any investment of monies by or at the direction of the Master Servicer or a Servicer or any loss resulting therefrom, it being understood that the Trustee and the Certificate Administrator shall remain responsible for any part of the Trust Estate that either party may hold in its individual capacity; the acts or omissions of any of the Depositor, the Master Servicer (other than if the Trustee shall assume the duties of a predecessor Master Servicer pursuant to Section 8.05 and thereupon only for the acts or omissions of the Trustee as successor Master Servicer), any Servicer, any Subservicer or any Mortgagor; any action of the Master Servicer (other than if the Trustee shall assume the duties of a predecessor Master Servicer pursuant to Section 8.05 and thereupon only for the acts or omissions of the Trustee as successor Master Servicer), any Servicer or any Subservicer taken in the name of the Trustee or the Certificate Administrator; the failure of the Master Servicer, any Servicer or any Subservicer to act or perform any duties required of it as agent of the Trustee or the Certificate Administrator hereunder; or any action by the Trustee or the Certificate Administrator taken at the instruction of the Master Servicer (other than if the Trustee shall assume the duties of a predecessor Master Servicer pursuant to Section 8.05 and thereupon only for the acts or omissions of the Trustee as successor Master Servicer) or any Servicer; provided, however, that the foregoing shall not relieve the Trustee or the Certificate Administrator of its obligation to perform its duties under this Agreement.

Section 9.04 Trustee and Certificate Administrator May Own Certificates. Each of the Trustee and the Certificate Administrator in their individual or any other capacities may

108

become the owner or pledgee of Certificates with the same rights it would have if it were not Trustee or Certificate Administrator and may otherwise deal with the Master Servicer, any Servicer, any Subservicer or any of their respective affiliates with the same right it would have if it were not the Trustee or the Certificate Administrator.

Section 9.05 Eligibility Requirements for Trustee, Certificate Administrator. Each of the Trustee and the Certificate Administrator hereunder shall at all times be (a) an institution the deposits of which are fully insured by the FDIC and (b) a corporation or banking association organized and doing business under the laws of the United States of America or of any State, authorized under such laws to exercise corporate trust powers, having a combined capital and surplus of not less than $50,000,000 and subject to supervision or examination by Federal or State authority and (c) with respect to every successor trustee or certificate administrator hereunder either an institution (i) the long-term unsecured debt obligations of which are rated at least “A” by Fitch and S&P and “A2” by Moody’s or (ii) whose serving as Trustee or Certificate Administrator hereunder would not result in the lowering of the ratings originally assigned to any Class of Certificates. The Trustee shall not be an affiliate of the Depositor, the Master Servicer or any Servicer. If such corporation or banking association publishes reports of condition at least annually, pursuant to law or to the requirements of the aforesaid supervising or examining authority, then for the purposes of this Section 9.05, the combined capital and surplus of such corporation or banking association shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. In case at any time the Trustee or the Certificate Administrator shall cease to be eligible in accordance with the provision of this Section 9.05, the Trustee or the Certificate Administrator, as the case may be, shall resign immediately in the manner and with the effect specified in Section 9.06. The Certificate Administrator and any successor Certificate Administrator may not be the Depositor or an affiliate of the Depositor, or an originator, the Master Servicer, a Servicer or subservicer of the Mortgage Loans, unless the Certificate Administrator is an institutional trust department.

Section 9.06 Resignation and Removal of Trustee and the Certificate Administrator. The Trustee may at any time resign and be discharged from the trust hereby created by giving written notice thereof to the Depositor, the Master Servicer and the Servicers and mailing a copy of such notice to all Holders of record. The Certificate Administrator may at any time resign (including in connection with the resignation or termination of the Master Servicer) by giving written notice thereof to the Trustee and the Depositor and mailing a copy of such notice to all Holders of record; provided that any resignation and removal of the Certificate Administrator shall not be effective unless and until the Master Servicer resigns and is removed in accordance with Section 7.04 hereof. The Trustee or the Certificate Administrator, as applicable, shall also mail a copy of such notice of resignation to each Rating Agency. Upon receiving such notice of resignation, the Depositor shall use its best efforts to promptly appoint a mutually acceptable successor Trustee or Certificate Administrator, as applicable, by written instrument, in duplicate, one copy of which instrument shall be delivered to the resigning Trustee or Certificate Administrator, as applicable, and one copy to the successor Trustee or Certificate Administrator, as applicable. If no successor Trustee or Certificate Administrator, as the case may be, shall have been so appointed and shall have accepted appointment within 30 days after the giving of such notice of resignation, the resigning Trustee or Certificate Administrator may

109

petition any court of competent jurisdiction for the appointment of a successor Trustee or Certificate Administrator.

If (i) at any time the Trustee or the Certificate Administrator shall cease to be eligible in accordance with the provisions of Section 9.05 and shall fail to resign after written request therefor by a Servicer, (ii) at any time the Trustee or the Certificate Administrator shall become incapable of acting, or shall be adjudged a bankrupt or insolvent, or a receiver or conservator of the Trustee or the Certificate Administrator or of their respective property shall be appointed, or any public officer shall take charge or control of the Trustee or the Certificate Administrator or of their respective property or affairs for the purpose of rehabilitation, conservation or liquidation, (iii) the Certificate Administrator fails to timely comply with Article XII, or (iv) the Certificate Administrator is the Master Servicer, and a successor master servicer is appointed pursuant to Section 7.05 or Sections 8.01 and 8.05, then the Depositor may remove the Trustee or the Certificate Administrator, as the case may be, and appoint a successor Trustee or Certificate Administrator by written instrument, in duplicate, one copy of which instrument shall be delivered to the Trustee or the Certificate Administrator, as applicable, so removed and one copy to the successor.

The Holders of Certificates evidencing not less than 50% of the Voting Rights may at any time remove the Trustee or the Certificate Administrator by written instrument or instruments delivered to the Servicers and the Trustee or the Certificate Administrator, as applicable; the Depositor shall thereupon use its best efforts to appoint a mutually acceptable successor Trustee or Certificate Administrator, as the case may be, in accordance with this Section 9.06.

Any resignation or removal of the Trustee or Certificate Administrator and appointment of a successor Trustee or successor Certificate Administrator pursuant to any of the provisions of this Section 9.06 shall become effective upon acceptance of appointment by the successor Trustee or Certificate Administrator, as the case may be, as provided in Section 9.07. Notwithstanding the foregoing, in the event the Certificate Administrator advises the Trustee that it is unable to continue to perform its obligations pursuant to the terms of this Agreement prior to the appointment of a successor, the Trustee shall be obligated to perform such obligations until a new Certificate Administrator is appointed. Such performance shall be without prejudice to any claim by a party hereto or beneficiary hereof resulting from the Certificate Administrator’s breach of its obligations hereunder. As compensation therefore, the Trustee shall be entitled to all fees the Certificate Administrator would have been entitled to if it had continued to act hereunder.

Section 9.07 Successor Trustee or Certificate Administrator. Any successor Trustee or successor Certificate Administrator appointed as provided in Section 9.06 shall execute, acknowledge and deliver to the Depositor and to its predecessor Trustee or Certificate Administrator, as applicable, an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor Trustee or Certificate Administrator shall become effective and such successor Trustee or Certificate Administrator, as the case may be, without any further act, deed or conveyance, shall become fully vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as Trustee or Certificate Administrator, as applicable, herein. The predecessor Trustee or

110

Certificate Administrator shall duly assign, transfer, deliver and pay over to the successor Trustee or Certificate Administrator, as the case may be, all related documents and statements, and money and other property held by it hereunder, together with all instruments of transfer and assignment or other documents properly executed as may be reasonably required to effect such transfer and such of the records or copies thereof maintained by the predecessor Trustee or Certificate Administrator in the administration hereof as may be reasonably requested by the successor Trustee or Certificate Administrator, as the case may be, and shall thereupon be discharged from all duties and responsibilities under this Agreement; provided, however, that if the predecessor Trustee or Certificate Administrator has been terminated pursuant to the third paragraph of Section 9.06, all reasonable expenses of the predecessor Trustee or Certificate Administrator incurred in complying with this Section 9.07 shall be reimbursed by the Trust.

No successor Trustee or Certificate Administrator shall accept appointment as provided in this Section 9.07 unless at the time of such appointment such successor Trustee or Certificate Administrator, as the case may be, shall be eligible under the provisions of Section 9.05.

Upon acceptance of appointment by a successor Trustee or Certificate Administrator, as applicable, as provided in this Section 9.07, the Certificate Administrator shall cooperate to mail notice of the succession of such Trustee or Certificate Administrator, as the case may be, hereunder to all Holders of Certificates at their addresses as shown in the Certificate Register and to each Rating Agency.

Section 9.08 Merger or Consolidation of Trustee or the Certificate Administrator. Any corporation or banking association into which either the Trustee or the Certificate Administrator may be merged or converted or with which it may be consolidated, or any corporation or banking association resulting from any merger, conversion or consolidation to which the Trustee or the Certificate Administrator shall be a party, or any corporation or banking association succeeding to all or substantially all of the corporate trust business of the Trustee or the Certificate Administrator, shall be the successor of the Trustee or the Certificate Administrator, as applicable, hereunder, if such corporation or banking association is eligible under the provisions of Section 9.05, without the execution or filing of any paper or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding.

Section 9.09 Appointment of Co-Trustee or Separate Trustee. Notwithstanding any of the provisions hereof, at any time, for the purpose of meeting any legal requirements of any jurisdiction in which any Mortgaged Property may at the time be located or for any other reason, the Master Servicer and the Trustee acting jointly shall have the power and shall execute and deliver all instruments to appoint one or more Persons approved by the Trustee as co-trustee or separate trustee of all or any part of the Trust Estate, and to vest in such Persons, in such capacity, such title to the Trust Estate, or any part thereof, and, subject to the other provision of this Section 9.09, such powers, duties, obligations, rights and trusts as the Master Servicer and the Trustee may consider necessary or desirable. If the Master Servicer shall not have joined in such appointment within ten days after the receipt by it of a request to do so, the Trustee alone shall have the power to make such appointment. No co-trustee or separate trustee hereunder shall be required to meet the terms of eligibility as a successor Trustee under Section 9.05 and no

111

notice to Holders of Certificates of the appointment of a co-trustee or a separate trustee shall be required under Section 9.07.

In the case of any appointment of a co-trustee or separate trustee pursuant to this Section 9.09, all rights, powers, duties and obligations conferred or imposed upon the Trustee shall be conferred or imposed upon and exercised or performed by the Trustee and such separate trustee or co-trustee jointly, except to the extent that under any law of any jurisdiction in which any particular acts are to be performed, the Trustee shall be incompetent or unqualified to perform such acts, in which event such rights, powers, duties and obligations (including the holding of title to the Trust Estate or any portion thereof in any such jurisdiction) shall be exercised and performed by such separate trustee or co-trustee at the direction of the Trustee. No trustee hereunder shall be held personally liable by reason of any act or omission of any other trustee hereunder; provided, however, that no appointment of a co-trustee or separate trustee hereunder shall relieve the Trustee of its obligations hereunder.

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

Any separate trustee or co-trustee may, at any time, constitute the Trustee its agent or attorney-in-fact, with full power and authority, to the extent not prohibited by law, to do any lawful act under or in respect of this Agreement on its behalf and in its name. If any separate trustee or co-trustee shall become incapable of acting, resign or be removed, or shall be adjudged a bankrupt or insolvent, or a receiver of its property shall be appointed, or any public officer shall take charge or control of such trustee or co-trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, all of its estates, properties, rights, remedies and trusts shall vest in and be exercised by the Trustee, to the extent permitted by law, without the appointment of a new or successor trustee.

Section 9.10 Authenticating Agents. The Trustee may appoint one or more authenticating agents (“Authenticating Agents”) which shall be authorized to act on behalf of the Trustee in authenticating or countersigning Certificates. Initially, the Authenticating Agent shall be HSBC Bank USA, National Association. Wherever reference is made in this Agreement to the authentication or countersigning of Certificates by the Trustee or the Trustee’s certificate of authentication or countersigning, such reference shall be deemed to include authentication or countersigning on behalf of the Trustee by an Authenticating Agent and a certificate of authentication or countersignature executed on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent must be acceptable to the Certificate Administrator and must be a corporation or banking association organized and doing business under the laws of the United States of America or of any State, having a combined capital and surplus of at least $15,000,000,

112

authorized under such laws to do a trust business and subject to supervision or examination by Federal or State authorities.

Any corporation or banking association into which any Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation or banking association resulting from any merger, conversion or consolidation to which any Authenticating Agent shall be a party, or any corporation or banking association succeeding to the corporate agency business of any Authenticating Agent, shall continue to be the Authenticating Agent without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent.

Any Authenticating Agent may at any time resign by giving written notice of resignation to the Trustee, the Certificate Administrator and to the Master Servicer. The Trustee may at any time terminate the agency of any Authenticating Agent by giving written notice of termination to such Authenticating Agent, the Certificate Registrar and to the Master Servicer. Upon receiving a notice of resignation or upon such a termination, or in case, at any time any Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section 9.10, the Trustee may appoint a successor Authenticating Agent, shall give written notice of such appointment to the Master Servicer and the Certificate Administrator and shall mail notice of such appointment to all Certificateholders. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers, duties and responsibilities of its predecessor hereunder, with like effect as if originally named as Authenticating Agent. Each Authenticating Agent shall be entitled to the rights and benefits and immunities of this Article IX.

Section 9.11 Trustee’s Fees and Expenses and Certificate Administrator’s Fees and Expenses. The Trustee, as compensation for its services hereunder, shall be entitled to an annual fee in an amount agreed upon between the Trustee and the Master Servicer, payable by the Master Servicer out of its own funds and not out of any funds of the Trust Estate. The Certificate Administrator will be entitled to all income and gain realized from any investment of funds in the Certificate Account, pursuant to Section 3.08, for the performance of its activities hereunder. The Trustee and the Certificate Administrator and any director, officer, employee or agent of the Trustee and the Certificate Administrator shall be indemnified by the Trust and held harmless against any loss, liability or expense (including reasonable attorney’s fees) (a) incurred in connection with (i) any claim or legal action relating to this Agreement or the Certificates or (ii) the performance of any of the Trustee’s or the Certificate Administrator’s duties hereunder, other than any loss, liability or expense incurred by reason of willful misfeasance, bad faith or negligence in the performance of any of its duties hereunder, (b) resulting from any tax or information return which was prepared by, or should have been prepared by, the Servicers or (c) arising out of the transfer of any Private Certificate not in compliance with ERISA. Such indemnity shall survive the termination of this Agreement or the resignation or removal of the Trustee or Certificate Administrator, as applicable, hereunder. Without limiting the foregoing, except as otherwise agreed upon in writing by the Depositor and the Trustee or the Certificate Administrator, as applicable, and except for any such expense, disbursement or advance as may arise from the Trustee’s or the Certificate Administrator’s negligence, bad faith or willful misconduct, the Trust shall reimburse the Trustee and the Certificate Administrator for all reasonable expenses, disbursements and advances incurred or made by the Trustee or the

113

Certificate Administrator, as applicable, in accordance with any of the provisions of this Agreement to the extent permitted by Treasury Regulations Section 1.860G-1(b)(3)(ii) and (iii).

All rights of action and claims under this Agreement or the Certificates may be prosecuted and enforced by the Trustee without the possession of any of the Certificates or the production thereof in any proceeding relating thereto, and such preceding instituted by the Trustee shall be brought in its own name or in its capacity as Trustee.

Section 9.16 Suits for Enforcement. In case an Event of Default or other default by the Master Servicer, any Servicer or the Depositor hereunder shall occur and be continuing, the Trustee, in its discretion, may proceed to protect and enforce its rights and the rights of the Holders of Certificates under this Agreement by a suit, action or proceeding in equity or at law or otherwise, whether for the specific performance of any covenant or agreement contained in this Agreement or in aid of the execution of any power granted in this Agreement or for the enforcement of any other legal, equitable or other remedy, as the Trustee, being advised by counsel, shall deem most effectual to protect and enforce any of the rights of the Trustee and the Certificateholders.

TERMINATION

Section 10.01 Termination upon Purchase by the Master Servicer or Liquidation of All Mortgage Loans. Subject to Section 10.02, the respective obligations and responsibilities of the Depositor, the Master Servicer, the Servicers, the Certificate Administrator and the Trustee created hereby (other than the obligation of Certificate Administrator to make certain payments to Certificateholders after the Final Distribution Date and to send certain notices as hereinafter set forth and the obligations of the Certificate Administrator pursuant to Sections 5.04(b) and 5.05(b)) shall terminate upon the last action required to be taken by the Certificate Administrator on the Final Distribution Date pursuant to this Article X following the earlier of (a) the purchase by Wells Fargo (or a successor Servicer thereto) of all Mortgage Loans and all REO Property remaining in the Trust Estate at a price equal to the sum of (i) 100% of the Stated Principal Balance of each Mortgage Loan (other than any Mortgage Loan as to which REO Property has been acquired and whose fair market value is included pursuant to clause (ii) below) and (ii) the fair market value of such REO Property (as determined by such Servicer as of the close of business on the third Business Day next preceding the date upon which notice of any such termination is furnished to Certificateholders pursuant to the fourth paragraph of this Article X), plus any Class Unpaid Interest Shortfall for any Class of Certificates as well as one month’s interest at the related Mortgage Interest Rate on the Stated Principal Balance of each Mortgage Loan (including any Mortgage Loan as to which REO Property has been acquired) or (b) the final payment or other liquidation (or any advance with respect thereto) of the last Mortgage Loan remaining in the Trust Estate or the disposition of all REO Property.

Regardless of the foregoing, in no event shall the Trust created hereby continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late ambassador of the United States to the Court of St. James’s, living on the date hereof.

The right of Wells Fargo (or a successor Servicer thereto) to repurchase all of the Mortgage Loans is conditioned upon the Pool Stated Principal Balance as of the Final Distribution Date being less than 5% of the Cut-off Date Pool Principal Balance. If such right is exercised, the Custodian shall, promptly following payment of the purchase price, release to Wells Fargo or its designee the Mortgage Files pertaining to the Mortgage Loans being purchased.

Notice of any termination, specifying the Final Distribution Date (which shall be a date that would otherwise be a Distribution Date) upon which the Certificateholders may surrender their Certificates to the Certificate Administrator for payment of the final distribution and for cancellation, shall be given promptly by Wells Fargo (if exercising its right to purchase the assets of the Trust) or by the Certificate Administrator (in any other case) by letter to Certificateholders mailed not earlier than the 15th day and not later than the 20th day of the

115

month next preceding the month of such final distribution specifying (1) the Final Distribution Date upon which final payment of the Certificates will be made upon presentation and surrender of Certificates at the office or agency of the Certificate Administrator therein designated, (2) the amount of any such final payment and (3) that the Record Date otherwise applicable to such Distribution Date is not applicable, payments being made only upon presentation and surrender of the Certificates at the office or agency of the Certificate Administrator therein specified. If Wells Fargo is obligated to give notice to Certificateholders as aforesaid, it shall give such notice to the Trustee, any other Servicer, the Certificate Administrator and the Certificate Registrar at the time such notice is given to Certificateholders. In the event such notice is given by Wells Fargo, Wells Fargo shall deposit in the Certificate Account on or before the Final Distribution Date in immediately available funds an amount equal to the amount necessary to make the amount, if any, on deposit in the Certificate Account on the Final Distribution Date equal to the purchase price for the related assets of the Trust computed as above provided together with a statement as to the amount to be distributed on each Class of Certificates pursuant to the next succeeding paragraph.

Upon presentation and surrender of the Certificates, the Certificate Administrator shall cause to be distributed to Certificateholders of each Class, to the extent that funds are sufficient therefor, in the order set forth in Section 5.02 hereof, on the Final Distribution Date and in proportion to their respective Percentage Interests, with respect to Certificateholders of the same Class, an amount equal to (I) as to each Class of Certificates, the Class Certificate Balance thereof plus accrued interest thereon in the case of an interest bearing Certificate and (II) as to the Class 1-A-R Certificates, the amounts, if any, which remain on deposit in the Upper-Tier Certificate Account (other than the amounts retained to meet claims) after application pursuant to clause (I) above.

If all of the Certificateholders do not surrender their Certificates for final payment and cancellation on or before the Final Distribution Date, the Certificate Administrator shall on such date cause all funds in the Certificate Account not distributed in final distribution to Certificateholders to continue to be held by the Certificate Administrator in an Eligible Account for the benefit of such Certificateholders and the Servicers (if it exercised its right to purchase the assets of the Trust Estate) or the Certificate Administrator (in any other case) shall give a second written notice to the remaining Certificateholders to surrender their Certificates for cancellation and receive the final distribution with respect thereto. If within one year after the second notice all the Certificates shall not have been surrendered for cancellation, the Certificate Administrator may take appropriate steps, or may appoint an agent to take appropriate steps, to contact the remaining Certificateholders concerning surrender of their Certificates, and the cost thereof shall be paid out of the funds on deposit in such Eligible Account.

Section 10.02 Additional Termination Requirements.

(a) If Wells Fargo exercises its purchase option as provided in Section 10.01, the Trust shall be terminated in accordance with the following additional requirements, unless the Certificate Administrator and the Trustee have received an Opinion of Counsel to the effect that the failure of the Trust to comply with the requirements of this Section 10.02 will not (i) result in the imposition of taxes on “prohibited transactions” of the Trust as defined in Section

116

860F of the Code, or (ii) cause the Trust Estate to fail to qualify as two separate REMICs at any time that any Certificates are outstanding:

(i) within 90 days prior to the Final Distribution Date set forth in the notice given by Wells Fargo under Section 10.01, the Trustee shall sell all of the assets of the Trust Estate to Wells Fargo for cash; and

(ii) the notice given by Wells Fargo or the Certificate Administrator pursuant to Section 10.01 shall provide that such notice constitutes the adopting of a plan of complete liquidation of the Upper-Tier REMIC and the Lower-Tier REMIC as of the date of such notice (or, if earlier, the date on which such notice was mailed to Certificateholders). The Certificate Administrator shall also specify such date in the final tax return of the Upper-Tier REMIC and Lower-Tier REMIC.

(b) By their acceptance of the Residual Certificates, the Holders thereof hereby agree to take such other action in connection with such plan of complete liquidation as may be reasonably requested by the Depositor, the Trustee or the Certificate Administrator.

ARTICLE XI

MISCELLANEOUS PROVISIONS

Section 11.01 Amendment. This Agreement may be amended from time to time by the Depositor, the Master Servicer, the Servicers, the Certificate Administrator and the Trustee without the consent of any of the Certificateholders, but if such amendment would adversely affect or add to the duties of the Custodian, with the consent of the Custodian (i) to cure any ambiguity or mistake, (ii) to correct or supplement any provisions herein or therein which may be inconsistent with any other provisions of this Agreement, any amendment to this Agreement, the Certificates or the related Prospectus Supplement, (iii) to modify, eliminate or add to any of its provisions to such extent as shall be necessary to maintain the qualification of the Upper-Tier REMIC and the Lower-Tier REMIC as REMICs at all times that any Certificates are outstanding or to avoid or minimize the risk of the imposition of any tax on either REMIC pursuant to the Code that would be a claim against the Trust Estate, provided that (a) the Trustee and the Certificate Administrator have received an Opinion of Counsel to the effect that such action is necessary or desirable to maintain such qualification or to avoid or minimize the risk of the imposition of any such tax and (b) such action shall not, as evidenced by such Opinion of Counsel, adversely affect in any material respect the interests of any Certificateholder, (iv) to change the timing and/or nature of deposits into the Certificate Account provided that (a) such change shall not, as evidenced by an Opinion of Counsel, adversely affect in any material respect the interests of any Certificateholder and (b) such change shall not adversely affect the then-current rating of the Senior Certificates, the Class B-1 Certificates, the Class B-2 Certificates, the Class B-3 Certificates, the Class B-4 Certificates or the Class B-5 Certificates as evidenced by a letter from any Rating Agency rating such Certificates to such effect, (v) to comply with Regulation AB, and (vi) to make any other provisions with respect to matters or questions arising under this Agreement which shall not be materially inconsistent with the provisions of this Agreement, provided that such action pursuant to this clause (vi) shall not, as evidenced by an Opinion of Counsel, adversely affect in any material respect the interests of any

117

Certificateholder, provided that the amendment shall not be deemed to adversely affect in any material respect the interests of the Certificateholders and no Opinion of Counsel to that effect shall be required if the Person requesting the amendment obtains a letter from each Rating Agency stating that the amendment would not result in the downgrading or withdrawal of the respective ratings then assigned to the Certificates. Notwithstanding any contrary provision of this Agreement, the Trustee shall not consent to any amendment to this Agreement for which consent of the Certificateholders has not been obtained unless it shall have first received an Opinion of Counsel (subject to Section 5.08 and at the expense of the party seeking such amendment) to the effect that such amendment or the exercise of any power granted to the Master Servicer, the Certificate Administrator, the Depositor or the Trustee in accordance with such amendment will not result in the imposition of a federal tax on the Trust or cause any REMIC created hereunder to fail to qualify as a REMIC at any time that any Certificate is outstanding.

This Agreement may also be amended from time to time by the Depositor, the Master Servicer, the Servicers, the Certificate Administrator and the Trustee, with the consent of the Holders of Certificates of each Class of Certificates which is affected by such amendment, evidencing, as to each such Class of Certificates, Percentage Interests aggregating not less than 66-2/3%, for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Agreement or of modifying in any manner the rights of the Holders of such Certificates; provided, however, that no such amendment shall (A) reduce in any manner the amount of, or delay the timing of, collections of payments on Mortgage Loans or distributions which are required to be made on any Certificate without the consent of the Holder of such Certificate or (B) reduce the aforesaid percentage required to consent to any such amendment, without the consent of the Holders of all Certificates then Outstanding.

Prior to the solicitation of consent of Certificateholders in connection with any such amendment, the party seeking such amendment shall furnish the Trustee and the Certificate Administrator with an Opinion of Counsel stating whether such amendment would adversely affect the qualification of the Upper-Tier REMIC or the Lower-Tier REMIC as REMICs and notice of the conclusion expressed in such Opinion of Counsel shall be included with any such solicitation. An amendment made with the consent of all Certificateholders and executed in accordance with this Section 11.01 shall be permitted or authorized by this Agreement notwithstanding that such Opinion of Counsel may conclude that such amendment would adversely affect the qualification of the Upper-Tier REMIC or the Lower-Tier REMIC as REMICs.

Prior to the execution of any amendment to this Agreement, the Trustee and the Certificate Administrator shall be entitled to receive and rely upon an Opinion of Counsel (which shall not be an expense of the Trust Estate) stating that the execution of such amendment is authorized and permitted by this Agreement. Each of the Certificate Administrator and the Trustee may, but shall not be obligated to, enter into any such amendment which adversely affects their respective own rights, duties and immunities under this Agreement.

It shall not be necessary for the consent of Certificateholders under this Section 11.01 to approve the particular form of any proposed amendment, but it shall be sufficient if such consent shall approve the substance thereof. The manner of obtaining such consents and of

118

evidencing the authorization of the execution thereof by Certificateholders shall be subject to such reasonable requirements as the Trustee may prescribe.

Section 11.02 Recordation of Agreement. This Agreement is subject to recordation in all appropriate public offices for real property records in all the counties or other comparable jurisdictions in which any or all of the properties subject to the Mortgages are situated, and in any other appropriate public recording office or elsewhere, such recordation to be effected by the Servicer servicing the related Mortgage Loans and at its expense on direction by the Depositor, who will act solely at the direction of Holders of Certificates evidencing not less than 50% of all Voting Rights, but only upon receipt of an Opinion of Counsel to the effect that such recordation materially and beneficially affects the interests of Certificateholders (which Opinion of Counsel shall not be at the expense of the Depositor).

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

Section 11.03 Limitation on Rights of Certificateholders. The death or incapacity of any Certificateholder shall not operate to terminate this Agreement or the Trust, nor entitle such Certificateholder’s legal representatives or heirs to claim an accounting or to take any action or commence any proceeding in any court for a partition or winding up of the Trust, nor otherwise affect the rights, obligations and liabilities of the parties hereto or any of them.

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

No Certificateholder shall have any right by virtue or by availing itself of any provisions of this Agreement to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Agreement, unless such Holder previously shall have given to the Trustee a written notice of default and of the continuance thereof, as provided herein, and unless also the Holders of Certificates evidencing Percentage Interests aggregating not less than 25% of each Class of Certificates affected thereby shall have made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder and shall have offered to the Trustee such reasonable indemnity as it may require against the costs, expenses and liabilities to be incurred therein or thereby, and the Trustee, for 60 days after its receipt of such notice, request and offer of indemnity, shall have neglected or refused to institute any such action, suit or proceeding; it being understood and intended, and being expressly covenanted by each Certificateholder with every other Certificateholder and the Trustee, that no one or more Holders of Certificates shall have any right in any manner whatever by virtue or by availing itself or themselves of any provisions of this Agreement to affect, disturb or prejudice the rights of the Holders of any other of the Certificates, or to obtain or seek to obtain priority over or preference

119

to any other such Holder, or to enforce any right under this Agreement, except in the manner herein provided and for the equal, ratable and common benefit of all Certificateholders. For the protection and enforcement of the provisions of this Section 11.03, each and every Certificateholder and the Trustee shall be entitled to such relief as can be given either at law or in equity.

Neither the Certificate Administrator nor the Master Servicer shall have any liability for any loss, expense, damage, claim arising out of or with respect to any failure to properly prepare and/or timely file such Form 10-K, where such failure results from the Certificate Administrator's inability or failure to obtain or receive, on a timely basis, any information from any other party hereto needed to prepare, arrange for execution or file such Form 10-K, not resulting from its own negligence, bad faith or willful misconduct.

Section 12.04 Form 8-K Reporting. Within four (4) Business Days after the occurrence of an event requiring disclosure on Form 8-K (each such event, a “Reportable Event"), and if requested by the Depositor, the Certificate Administrator shall prepare and file on behalf of the Trust any Form 8-K, as required by the 1934 Act, provided that the Depositor shall file the initial Form 8-K in connection with the issuance of the Certificates.

As set forth on Exhibit U hereto, for so long as the Trust is subject to the 1934 Act reporting requirements, no later than the end of business (New York City time) on the 2nd Business Day after the occurrence of a Reportable Event (i) the parties to this transaction shall be required to provide to the Certificate Administrator and the Depositor, to the extent known by a responsible officer thereof, in EDGAR-compatible form, or in such other form as otherwise agreed upon by the Certificate Administrator and such party, the form and substance of any Form 8-K Disclosure Information, if applicable, together with an Additional Disclosure Notification and (ii) the Depositor will approve, as to form and substance, or disapprove, as the case may be, the inclusion of the Form 8-K Disclosure Information. The Depositor will be responsible for any reasonable fees and expenses assessed or incurred by the Certificate Administrator in connection with including any Form 8-K Disclosure Information on Form 8-K pursuant to this paragraph.

After preparing the Form 8-K, the Certificate Administrator shall forward electronically a draft copy of the Form 8-K to the Depositor for review. Promptly, but no later than the close of business on the 3rd Business Day after the Reportable Event, the Depositor shall notify the Certificate Administrator in writing of any changes to or approval of such Form 8-K. In the absence of receipt of any written changes or approval, the Certificate Administrator shall be entitled to assume that such Form 8-K is in final form and a duly authorized representative of the Certificate Administrator may proceed with the execution and filing of the Form 8-K. A duly authorized representative of the Master Servicer shall sign the Form 8-K. If a Form 8-K cannot be filed on time or if a previously filed Form 8-K needs to be amended, the Certificate Administrator will follow the procedures set forth in Section 12.05. Promptly (but no later than 1 Business Day) after filing with the Commission, the Certificate Administrator will make available on its internet website a final executed copy of each Form 8-K prepared and filed by the Certificate Administrator. The parties to this Agreement acknowledge that the

125

performance by the Certificate Administrator and the Master Servicer of its duties under this Section 12.04 related to the timely preparation and filing of Form 8-K is contingent upon such parties strictly observing all applicable deadlines in the performance of their duties under this Section 12.04. Neither the Master Servicer nor the Certificate Administrator shall have any liability for any loss, expense, damage or claim arising out of or with respect to any failure to properly prepare and/or timely file such Form 8-K, where such failure results from the Certificate Administrator's inability or failure to obtain or receive, on a timely basis, any information from any other party hereto needed to prepare, arrange for execution or file such Form 8-K, not resulting from its own negligence, bad faith or willful misconduct.

Section 12.05 Delisting; Amendment; Late Filing of Reports. On or before January 30 of the first year in which the Certificate Administrator is able to do so under applicable law, the Certificate Administrator shall prepare and file a Form 15 Suspension Notification relating to the automatic suspension of reporting in respect of the Trust under the 1934 Act.

In the event that the Certificate Administrator is unable to timely file with the Commission all or any required portion of any Form 8-K, 10-D or 10-K required to be filed by this Agreement because required disclosure information was either not delivered to it or delivered to it after the delivery deadlines set forth in this Agreement or for any other reason, the Certificate Administrator shall promptly notify electronically the Depositor. In the case of Form 10-D and 10-K, the parties to this Agreement shall cooperate to prepare and file a Form 12b-25 and a 10-D/A and 10-K/A as applicable, pursuant to Rule 12b-25 of the 1934 Act. In the case of Form 8-K, the Certificate Administrator will, upon receipt of all required Form 8-K Disclosure Information and upon the approval and direction of the Depositor, include such disclosure information on the next Form 10-D. In the event that any previously filed Form 8-K, 10-D or 10-K needs to be amended in connection with any additional Form 10-D Disclosure (other than for the purpose of restating the Monthly Report), the Certificate Administrator shall electronically notify the Depositor and such parties will cooperate to prepare any necessary Form 8-K/A, 10-D/A or 10-K/A. Any Form 15, Form 12b-25 or any amendment to Form 8-K or 10-D shall be signed by a duly authorized representative of the Master Servicer. Any amendment to Form 10-K shall be signed by the Depositor. The parties to this Agreement acknowledge that the performance by the Certificate Administrator and the Master Servicer of their duties under this Section 12.05 related to the timely preparation and filing of Form 15, a Form 12b-25 or any amendment to Form 8-K, 10-D or 10-K is contingent upon each such party performing its duties under this Section. Neither the Certificate Administrator nor the Master Servicer shall have any liability for any loss, expense, damage or claim arising out of or with respect to any failure to properly prepare and/or timely file any such Form 15, Form 12b-25 or any amendments to Forms 8-K, 10-D or 10-K, where such failure results from the Certificate Administrator's inability or failure to obtain or receive, on a timely basis, any information from any other party hereto needed to prepare, arrange for execution or file such Form 15, Form 12b-25 or any amendments to Forms 8-K, 10-D or 10-K, not resulting from its own negligence, bad faith or willful misconduct.

Section 12.06 Annual Statements of Compliance. The Master Servicer, the Certificate Administrator and each Servicer shall deliver or otherwise make available (and the Master Servicer, the Certificate Administrator and each Servicer shall cause any Servicing

126

Function Participant engaged by it to deliver or otherwise make available) to the Depositor, the Trustee and the Certificate Administrator on or before March 15 of each year, commencing in March 2007, an Officer's Certificate (an “Item 1123 Certificate”) stating, as to the signer thereof, that (A) a review of such party's activities during the preceding calendar year or portion thereof and of such party's performance under this Agreement, or such other applicable agreement in the case of a Servicing Function Participant, has been made under such officer's supervision and (B) to the best of such officer's knowledge, based on such review, such party has fulfilled all its obligations under this Agreement, or such other applicable agreement in the case of a Servicing Function Participant, in all material respects throughout such year or portion thereof, or, if there has been a failure to fulfill any such obligation in any material respect, specifying each such failure known to such officer and the nature and status thereof. Promptly after receipt of each such Item 1123 Certificate, the Depositor shall review such Item 1123 Certificate and, if applicable, consult with each such party, as applicable, as to the nature of any failures by such party, in the fulfillment of any of such party's obligations hereunder or, in the case of an Additional Servicer, under such other applicable agreement.

The Master Servicer shall include all annual statements of compliance received by it from each Servicer with its own annual statement of compliance to be submitted to the Certificate Administrator pursuant to this Section.

In the event the Master Servicer, the Certificate Administrator or any Servicing Function Participant engaged by any such party is terminated or resigns pursuant to the terms of this Agreement, or any applicable agreement in the case of a Servicing Function Participant, as the case may be, such party shall provide an Item 1123 Certificate pursuant to this Section 12.06 or to such applicable agreement, as the case may be, notwithstanding any such termination, assignment or resignation.

The Master Servicer shall enforce any obligation of the Custodian, to the extent set forth in the Custodial Agreement, to deliver to the Master Servicer an Item 1123 Certificate as may be required pursuant to the Custodial Agreement. The Master Servicer shall include such Item 1123 Certificate with its own Item 1123 Certificate to be submitted to the Certificate Administrator, the Depositor and the Trustee pursuant to this Section.

Section 12.07 Annual Assessments of Compliance. By March 15 of each year, commencing in March 2007, the Master Servicer, the Certificate Administrator and each Servicer, each at its own expense, shall furnish or otherwise make available, and each such party shall cause any Servicing Function Participant engaged by it to furnish or otherwise make available, each at its own expense, to the Certificate Administrator, the Trustee and the Depositor, a report on an assessment of compliance with the Relevant Servicing Criteria (an “Assessment of Compliance”) that contains (A) a statement by such party of its responsibility for assessing compliance with the Relevant Servicing Criteria for each party as set forth on Exhibit R, (B) a statement that such party used the Relevant Servicing Criteria to assess compliance with the Relevant Servicing Criteria, (C) such party's assessment of compliance with the Relevant Servicing Criteria as of and for the fiscal year covered by the Form 10-K required to be filed pursuant to Section 12.03, including, if there has been any material instance of noncompliance with the Relevant Servicing Criteria, a discussion of each such failure and the nature and status thereof, and (D) a statement that a registered public accounting firm has issued an Accountant's

127

Attestation on such party's Assessment of Compliance with the Relevant Servicing Criteria as of and for such period.

No later than the end of each fiscal year for the Trust for which a 10-K is required to be filed, each Servicer and the Master Servicer shall each forward to the Certificate Administrator the name of each Servicing Function Participant engaged by it and what Relevant Servicing Criteria will be addressed in the Assessment of Compliance prepared by such Servicing Function Participant (provided, however, that the Master Servicer need not provide information to the Certificate Administrator so long as the Master Servicer and the Certificate Administrator are the same person). When the Master Servicer and each Servicer (or any Servicing Function Participant engaged by them) submit their Assessments of Compliance to the Certificate Administrator, such parties will also at such time include the Assessments of Compliance (and Accountant's Attestation) pursuant to Section 12.08 of each Servicing Function Participant engaged by it.

Promptly after receipt of each Assessment of Compliance, the Depositor shall review each such report and, if applicable, consult with the Master Servicer, the Certificate Administrator, each Servicer and any Servicing Function Participant engaged by such parties as to the nature of any material instance of noncompliance with the Relevant Servicing Criteria by each such party. None of such parties will be required to deliver any such assessments until April 15 in any given year so long as it has received written confirmation from the Depositor that a Form 10-K is not required to be filed in respect of the Trust for the preceding calendar year.

The Master Servicer shall include all annual reports on assessment of compliance received by it from the Servicers with its own assessment of compliance to be submitted to the Certificate Administrator pursuant to this Section.

In the event the Master Servicer, the Certificate Administrator or any Servicing Function Participant engaged by any such party is terminated, assigns its rights and obligations under, or resigns pursuant to, the terms of this Agreement, or any other applicable agreement, as the case may be, such party shall provide a report on assessment of compliance pursuant to this Section 12.07, or such other applicable agreement, notwithstanding any such termination, assignment of resignation.

The Master Servicer shall enforce any obligation of the Custodian, to the extent set forth in the Custodial Agreement to deliver to the Master Servicer an Assessment of Compliance within the time frame set forth in, and in such form and substance as may be required pursuant to the Custodial Agreement. The Master Servicer shall include such Assessment of Compliance with its own Assessment of Compliance to be submitted to the Certificate Administrator and the Trustee pursuant to this Section.

Section 12.08 Accountant's Attestation. By March 15 of each year, commencing in 2007, the Master Servicer, the Certificate Administrator and each Servicer, each at its own expense, shall cause, and each such party shall cause any Servicing Function Participant engaged by it to cause, each at its own expense, a registered public accounting firm (which may also render other services to the Master Servicer, the Certificate Administrator or a Servicer or such other Servicing Function Participants, as the case may be) and that is a member of the American

128

Institute of Certified Public Accountants to furnish a report (the “Accountant's Attestation”) to the Certificate Administrator and the Depositor, to the effect that (i) it has obtained a representation regarding certain matters from the management of such party, which includes an assertion that such party has complied with the Relevant Servicing Criteria, and (ii) on the basis of an examination conducted by such firm in accordance with standards for attestation engagements issued or adopted by the PCAOB, it is expressing an opinion as to whether such party's compliance with the Relevant Servicing Criteria was fairly stated in all material respects, or it cannot express an overall opinion regarding such party's assessment of compliance with the Relevant Servicing Criteria. In the event that an overall opinion cannot be expressed, such registered public accounting firm shall state in such report why it was unable to express such an opinion. Such report must be available for general use and not contain restricted use language.

Promptly after receipt of such Accountant's Attestations from the Master Servicer, each Servicer, the Custodian, the Certificate Administrator or any Servicing Function Participant engaged by such parties, (i) the Depositor shall review the report and, if applicable, consult with such parties as to the nature of any defaults by such parties, in the fulfillment of any of each such party's obligations hereunder or under any other applicable agreement, and (ii) the Certificate Administrator shall confirm that each Assessment of Compliance is coupled with an Accountant's Attestation meeting the requirements of this Section and notify the Depositor of any exceptions. None of such parties shall be required to deliver any such assessments until April 15 in any given year so long as it has received written confirmation from the Depositor that a Form 10-K is not required to be filed in respect of the Trust for the preceding calendar year.

The Master Servicer shall include each such attestation furnished to it by the Servicers with its own attestation to be submitted to the Certificate Administrator pursuant to this Section.

In the event the Master Servicer, the Certificate Administrator, the Custodian, any Servicer or any Servicing Function Participant engaged by any such party, is terminated, assigns its rights and duties under, or resigns pursuant to the terms of, this Agreement, or any applicable Custodial Agreement or any applicable Subservicing Agreement, as the case may be, such party shall, at its sole expense, cause a registered public accounting firm to provide an attestation pursuant to this Section 12.08, or such other applicable agreement, notwithstanding any such termination, assignment or resignation.

The Master Servicer shall enforce any obligation of the Custodian, to the extent set forth in the Custodial Agreement to deliver to the Master Servicer an attestation as may be required pursuant to the Custodial Agreement. The Master Servicer shall include each such attestation with its own Accountant's Attestation to be submitted to the Certificate Administrator pursuant to this Section.

Section 12.09 Sarbanes-Oxley Certification. Each Form 10-K shall include a certification (the "Sarbanes-Oxley Certification”) required to be included therewith pursuant to the Sarbanes-Oxley Act. Each Servicer, the Master Servicer and the Certificate Administrator shall provide, and each Servicer, the Master Servicer and the Certificate Administrator shall cause any Servicing Function Participant engaged by it to, provide to the Person who signs the Sarbanes-Oxley Certification (the “Certifying Person”), by March 15 of each year in which the

129

Trust is subject to the reporting requirements of the 1934 Act and otherwise within a reasonable period of time upon request, a certification (each, a “Back-Up Certification”), in the form attached hereto as Exhibit Q, upon which the Certifying Person, the entity for which the Certifying Person acts as an officer, and such entity's officers, directors and Affiliates (collectively with the Certifying Person, “Certification Parties”) can reasonably rely. The Depositor shall serve as the Certifying Person on behalf of the Trust. In the event the Master Servicer, the Certificate Administrator or any Servicing Function Participant engaged by such party is terminated or resigns pursuant to the terms of this Agreement, or any applicable Subservicing Agreement, as the case may be, such party shall provide a Back-Up Certification to the Certifying Person pursuant to this Section 12.09 with respect to the period of time it was subject to this Agreement or any applicable Subservicing Agreement, as the case may be.

Section 12.10 Indemnification. Each party required to deliver an Assessment of Compliance and an Accountant's Attestation and/or an Item 1123 Certification under Article XII (each, a “Responsible Party”) shall indemnify and hold harmless the Certificate Administrator, the Master Servicer and the Depositor and each of their directors, officers, employees, agents, and affiliates from and against any and all claims, losses, damages, penalties, fines, forfeitures, reasonable legal fees and related costs, judgments and other costs and expenses arising out of or based upon (a) any breach by such Responsible Party of any if its obligations under this Article XII including particularly its obligation to provide any Assessment of Compliance and an Accountant's Attestation and/or an Item 1123 Certification or any information, data or material required to be included in any 1934 Act report, (b) any misstatement or omission in any information, data or materials provided by such Responsible Party (or, in the case of the Certificate Administrator or Master Servicer, any material misstatement of material omission in (i) any Compliance Statement, Assessment of Compliance or Attestation report delivered by it, or by any Servicing Function Participant engaged by it, pursuant to this Agreement, or (ii) any Additional Form 10-D Disclosure, Additional Form 10-K Disclosure concerning the Master Servicer or the Certificate Administrator), or (c) the negligence, bad faith or willful misconduct of such Responsible Party in connection with the performance of any if its obligations hereunder. If the indemnification provided for herein is unavailable or insufficient to hold harmless the Master Servicer, the Certificate Administrator or the Depositor, then each Responsible Party agrees that it shall contribute to the amount paid or payable by Certificate Administrator, the Master Servicer or the Depositor, as applicable, as a result of any claims, losses, damages or liabilities incurred by the Master Servicer, the Certificate Administrator or the Depositor, as applicable, in such proportion as is appropriate to reflect the relative fault of the Master Servicer, the Certificate Administrator or the Depositor, as applicable, on the one hand and such Responsible Party, on the other. This indemnification shall survive the termination of this Agreement or the termination of any party to this Agreement.

APPENDIX 1

CALCULATION OF UNCERTIFICATED LOWER-TIER REGULAR INTEREST Y PRINCIPAL REDUCTION AMOUNTS

Uncertificated Lower-Tier Regular Interest Y Principal Reduction Amounts: For any
Distribution Date the amounts by which the Uncertificated Principal Balances of
Uncertificated Lower-Tier Regular Interests Y-1, Y-2, Y-3 and Y-4, respectively, will be
reduced on such Distribution Date by the allocation of Realized Losses and the distribution
of principal, determined as follows:

First, for each of Loan Group 1, Loan Group 2, Loan Group 3 and Loan Group 4,
determine the Net WAC for the applicable Loan Group for distributions of interest that will
be made on the next succeeding Distribution Date (the "Group Interest Rate"). The
Uncertificated Lower-Tier Regular Interest Y Principal Reduction Amount for Uncertificated
Lower-Tier Regular Interests Y-1, Y-2, Y-3 and Y-4 will be determined pursuant to the
"Generic solution for the Uncertificated Lower-Tier Regular Interest Y Principal Reduction
Amounts" set forth below (the "Generic Solution") by making identifications among the
actual Loan Groups and their related Uncertificated Lower-Tier Regular Interests and the
Net WAC and the Groups named in the Generic Solution and their related Uncertificated
Lower-Tier Regular Interests as follows:

A. Determine which Group has the lowest Group Interest Rate. That Group will be
identified with Group AA and the Uncertificated Lower-Tier Regular Interests related to
that Group will be respectively identified with Uncertificated Lower-Tier Regular Interests
Y-AA and Z-AA. The Group Interest Rate for that Group will be identified with J%. If two
or more Groups have the lowest Group Interest Rate pick one for this purpose, subject to
the restriction that each Group may be picked only once in the course of any such
selections pursuant to paragraphs A through D of this definition.

B. Determine which Group has the second lowest Group Interest Rate. That Group will be
identified with Group BB and the Uncertificated Lower-Tier Regular Interests related to
that Group will be respectively identified with Uncertificated Lower-Tier Regular Interests
Y-BB and Z-BB. The Group Interest Rate for that Group will be identified with K%. If two
or more Groups have the second lowest Group Interest Rate pick one for this purpose,
subject to the restriction that each Group may be picked only once in the course of any
such selections pursuant to paragraphs A through D of this definition.

C. Determine which Group has the third lowest Group Interest Rate. That Group will be
identified with Group CC and the Uncertificated Lower-Tier Regular Interests related to
that Group will be respectively identified with Uncertificated Lower-Tier Regular Interests
Y-CC and Z-CC. The Group Interest Rate for that Group will be identified with L%. If two
or more Groups have the third lowest Group Interest Rate pick one for this purpose, subject
to the restriction that each Group may be picked only once in the course of any such
selections pursuant to paragraphs A through D of this definition.

D. Determine which Group has the fourth lowest Group Interest Rate. That Group will be
identified with Group DD and the Uncertificated Lower-Tier Regular Interests related to
that Group will be respectively identified with Uncertificated Lower-Tier Regular Interests
Y-DD and Z-DD. The Group Interest Rate for that Group will be identified with M%. If two
or more Groups have the fourth lowest Group Interest Rate pick one for this purpose,
subject to the restriction that each Group may be picked only once in the course of any
such selections pursuant to paragraphs A through D of this definition.

Second, apply the Generic Solution set forth below to determine the Uncertificated
Lower-Tier Regular Interest Y Principal Reduction Amounts for the Distribution Date using
the identifications made above.

Generic Solution for the Uncertificated Lower-Tier Regular Interest Y Principal
Reduction Amounts: For any Distribution Date, the amounts by which the Uncertificated
Principal Balances of Uncertificated Lower-Tier Regular Interests Y-AA, Y-BB, Y-CC and
Y-DD, respectively, will be reduced on such Distribution Date by the allocation of Realized
Losses and the distribution of principal, determined as follows:

For purposes of the succeeding formulas the following symbols shall have the meanings set
forth below:

J% = the Net WAC for Group AA for interest to be distributed on the next succeeding
Distribution Date.

K% = the Net WAC for Group BB for interest to be distributed on the next succeeding
Distribution Date.

L% = the Net WAC for Group CC for interest to be distributed on the next succeeding
Distribution Date.

M% = the Net WAC for Group DD for interest to be distributed on the next succeeding
Distribution Date.

For purposes of the succeeding definitions and formulas, it is required that J%<=K%<=L%<=M%.

PJB = the Group AA Subordinate Percentage after the allocation of Realized Losses and
distributions of principal on such Distribution Date.

PKB = the Group BB Subordinate Percentage after the allocation of Realized Losses and
distributions of principal on such Distribution Date.

PLB = the Group CC Subordinate Percentage after the allocation of Realized Losses and
distributions of principal on such Distribution Date.

PMB = the Group DD Subordinate Percentage after the allocation of Realized Losses and
distributions of principal on such Distribution Date.

R = the Class B Pass-Through Rate
= (J%PJB + K%PKB + L%PLB + M%PMB)/(PJB + PKB + PLB + PMB)

R11 = the weighted average of the Net WACs for Group AA, Group BB, Group CC and Group DD

}/(Pj - ΔPj + Pk - ΔPk + Pl - ΔPl )

R22 = the Net WAC for Group DD
       =    { M% (Pm - ΔPm)}/( Pm - ΔPm )

R31 = the weighted average of the Net WACs for Group AA and Group BB after giving effect to
      the allocation of Realized Losses and distributions of principal to be made on such
      Distribution Date
       =    {(J% (Pj - ΔPj) + K% (Pk - ΔPk) }/(Pj - ΔPj + Pk - ΔPk)

R32 = the weighted average of the Net WACs for Group CC and Group DD after giving effect to
      the allocation of Realized Losses and distributions of principal to be made on such
      Distribution Date
       =    { L% (Pl - ΔPl) + M% (Pm - ΔPm)}/( Pl - ΔPl + Pm - ΔPm)

R41 = the Net WAC for Group AA after giving effect to the allocation of Realized Losses and
      distributions of principal to be made on such Distribution Date
       =    J%

R42 = the weighted average of the Net WACs for Group BB, Group CC and Group DD after giving
      effect to the allocation of Realized Losses and distributions of principal to be made
      on such Distribution Date
            =     {K% (Pk - ΔPk) + L% (Pl - ΔPl) + M% (Pm - ΔPm)}/
                        ( Pk - ΔPk + Pl - ΔPl + Pm - ΔPm )

r11 = the weighted average of the Uncertificated Pass-Through Rates for Uncertificated
      Lower-Tier Regular Interests Y-AA, Y-BB, Y-CC and Y-DD
      =     (J% Yj + K% Yk + L% Yl + M% Ym )/(Yj + Yk + Yl + Ym )

r21 = the weighted average of the Uncertificated Pass-Through Rates for Uncertificated
      Lower-Tier Regular Interests Y-AA, Y-BB and Y-CC
      =     (J% Yj + K% Yk + L% Yl )/(Yj + Yk + Yl )

r22 = the Uncertificated Pass-Through Rate for Uncertificated Lower-Tier Regular Interest
      Y-DD
      =     ( M% Ym)/( Ym )

                                        3

r31 = the weighted average of the Uncertificated Pass-Through Rates for Uncertificated
      Lower-Tier Regular Interests Y-AA and Y-BB
      =     (J% Yj + K% Yk )/(Yj + Yk )

r32 = the weighted average of the Uncertificated Pass-Through Rates for Uncertificated
      Lower-Tier Regular Interests Y-CC and Y-DD
      =     ( L% Yl + M% Ym )/( Yl + Ym)

r41 = the Uncertificated Pass-Through Rate for Uncertificated Lower-Tier Regular Interest
      Y-AA
      =     J%

The purpose of the foregoing definitional provisions together with the related provisions
allocating Realized Losses and defining the Principal Distribution Amounts for the
respective Uncertificated Lower-Tier Regular Interests is to accomplish the following goals
in the following order of priority:

1.    Making the ratio of (Yn - ΔYn ) to (Y11 - ΔY11 ) equal to γ1 after taking
      account of the allocation Realized Losses and the distributions that will be made
      through the end of the Distribution Date to which such provisions relate and assuring
      that each of the Uncertificated Lower-Tier Regular Interest Y Principal Reduction
      Amounts and Uncertificated Lower-Tier Regular Interest Z Principal Reduction Amounts
      is greater than or equal to zero for such Distribution Date;

2.    Making the Uncertificated Principal Balance of Uncertificated Lower-Tier Regular
      Interest Y-AA less than or equal to 0.0005 of the sum of the Uncertificated Principal
      Balances of Uncertificated Lower-Tier Regular Interest Y-AA and Uncertificated
      Lower-Tier Regular Interest Z-AA, the Uncertificated Principal Balance of
      Uncertificated Lower-Tier Regular Interest Y-BB less than or equal to 0.0005 of the
      sum of the Uncertificated Principal Balances of Uncertificated Lower-Tier Regular
      Interest Y-BB and Uncertificated Lower-Tier Regular Interest Z-BB, the Uncertificated
      Principal Balance of Uncertificated Lower-Tier Regular Interest Y-CC less than or
      equal to 0.0005 of the sum of the Uncertificated Principal Balances of Uncertificated
      Lower-Tier Regular Interest Y-CC and Uncertificated Lower-Tier Regular Interest Z-CC,
      and the Uncertificated Principal Balance of Uncertificated Lower-Tier Regular
      Interest Y-DD less than or equal to 0.0005 of the sum of the Uncertificated Principal
      Balances of Uncertificated Lower-Tier Regular Interest Y-DD and Uncertificated
      Lower-Tier Regular Interest Z-DD in each case after giving effect to allocations of
      Realized Losses and distributions to be made through the end of the Distribution Date
      to which such provisions relate; and

                                        9

3.    Making the larger of (a) the fraction whose numerator is (Yn - ΔYn ) and whose
      denominator is the sum of (Yn - ΔYn) and (Zn - ΔZn) and (b) the fraction whose
      numerator is (Y11 - ΔY11) and whose denominator is the sum of (Y11 - ΔY11) and (Z11 -
      ΔZ11) as large as possible while remaining less than or equal to 0.0005.

In the event of a failure of the foregoing portion of the definition of Uncertificated
Lower-Tier Regular Interest Y Principal Reduction Amounts to accomplish both of goals 1 and
2 above, the amounts thereof should be adjusted to so as to accomplish such goals within
the requirement that each Uncertificated Lower-Tier Regular Interest Y Principal Reduction
Amount must be less than or equal to the sum of (a) the Principal Realized Losses to be
allocated on the related Distribution Date for the related Loan Group remaining after the
allocation of such Realized Losses to the related class of ratio-strip principal only
certificates, if any, and (b) the remainder of the Pool Distribution Amount for the related
Loan Group or after reduction thereof by the distributions to be made on such Distribution
Date (i) to the related class of ratio-strip principal only certificates, if any, (ii) to
the related class of ratio-strip interest only certificates, if any, and (iii) in respect
of interest on the related Uncertificated Lower-Tier Regular Interests, or, if both of such
goals cannot be accomplished within such requirement, such adjustment as is necessary shall
be made to accomplish goal 1 within such requirement.  In the event of any conflict among
the provisions of the definition of Uncertificated Lower-Tier Regular Interest Y Principal
Reduction Amounts, such conflict shall be resolved on the basis of the goals and their
priorities set forth above within the requirement set forth in the preceding sentence.  If
the formula allocation of ΔY11 among ΔYj, ΔYk, ΔYl and ΔYm cannot be achieved because one
or more of ΔYj, ΔYk, ΔYl and ΔYm, as so defined is greater than the related one of ΔPj,
ΔPk, ΔPl and ΔPm, such an allocation shall be made as close as possible to the formula
allocation within the requirement that ΔYj < ΔPj, ΔYk < ΔPk, ΔYl < ΔPl, ΔYm < ΔPm and ΔYm <
ΔPm.

      after taking account of the allocation Realized Losses and the distributions that
      will be made through the end of the Distribution Date to which such provisions relate
      and assuring that each of the Uncertificated Lower-Tier Regular Interest Y Principal
      Reduction Amounts and Uncertificated Lower-Tier Regular Interest Z Principal
      Reduction Amounts is greater than or equal to zero for such Distribution Date;

                                       12

      Balances of Uncertificated Lower-Tier Regular Interests Y-AA and Uncertificated

      Lower-Tier Regular Interest Z-DD, in each case after giving effect to allocations of
      Realized Losses and distributions to be made through the end of the Distribution Date
      to which such provisions relate; and

3.    Making the larger of (a) the fraction whose numerator is (Y22 - ΔY22 ) and
      whose denominator is the sum of (Y22 - ΔY22) and (Z22 - ΔZ22) and (b) the

allocated on the related Distribution Date for the related Loan Group remaining after the
allocation of such Realized Losses to the related class of ratio-strip principal only
certificates, if any, and (b) the remainder of the Pool Distribution Amount for the related
Loan Group or after reduction thereof by the distributions to be made on such Distribution
Date (i) to the related class of ratio-strip principal only certificates, if any, (ii) to
the related class of ratio-strip interest only certificates, if any, and (iii) in respect
of interest on the related Uncertificated Lower-Tier Regular Interests, or, if both of such
goals cannot be accomplished within such requirement, such adjustment as is necessary shall
be made to accomplish goal 1 within such requirement.  In the event of any conflict among
the provisions of the definition of the Uncertificated Lower-Tier Regular Interest Y
Principal Reduction Amounts, such conflict shall be resolved on the basis of the goals and

The purpose of the foregoing definitional provisions together with the related provisions
allocating Realized Losses and defining the Principal Distribution Amounts for the
respective Uncertificated Lower-Tier Regular Interests is to accomplish the following goals
in the following order of priority:

1.    Making the ratio of (Y42 - ΔY42 ) to (Yj - ΔYj ) equal to γ4 after
      taking account of the allocation Realized Losses and the distributions that will be
      made through the end of the Distribution Date to which such provisions relate and
      assuring that each of the Uncertificated Lower-Tier Regular Interest Y Principal
      Reduction Amounts and Uncertificated Lower-Tier Regular Interest Z Principal
      Reduction Amounts is greater than or equal to zero for such Distribution Date;

2.    Making the Uncertificated Principal Balance of Uncertificated Lower-Tier Regular
      Interest Y-AA less than or equal to 0.0005 of the sum of the Uncertificated Principal
      Balances of Uncertificated Lower-Tier Regular Interests Y-AA and Uncertificated

                                        19

      Lower-Tier Regular Interest Z-AA, the Uncertificated Principal Balance of
      Uncertificated Lower-Tier Regular Interest Y-BB less than or equal to 0.0005 of the
      sum of the Uncertificated Principal Balances of Uncertificated Lower-Tier Regular
      Interest Y-BB and Uncertificated Lower-Tier Regular Interest Z-BB, the Uncertificated
      Principal Balance of Uncertificated Lower-Tier Regular Interest Y-CC less than or
      equal to 0.0005 of the sum of the Uncertificated Principal Balances of Uncertificated
      Lower-Tier Regular Interest Y-CC and Uncertificated Lower-Tier Regular Interest Z-CC
      and the Uncertificated Principal Balance of Uncertificated Lower-Tier Regular
      Interest Y-DD less than or equal to 0.0005 of the sum of the Uncertificated Principal
      Balances of Uncertificated Lower-Tier Regular Interest Y-DD and Uncertificated
      Lower-Tier Regular Interest Z-DD, in each case after giving effect to allocations of
      Realized Losses and distributions to be made through the end of the Distribution Date
      to which such provisions relate; and

3.    Making the larger of (a) the fraction whose numerator is (Y42 - ΔY42 ) and
      whose denominator is the sum of (Y42 - ΔY42) and (Z42 - ΔZ42) and (b) the
      fraction whose numerator is (Yj - ΔYj) and whose denominator is the sum of (Yj
      - ΔYj) and (Zj - ΔZj) as large as possible while remaining less than or
      equal to 0.0005.

In the event of a failure of the foregoing portion of the definition of Uncertificated
Lower-Tier Regular Interest Y Principal Reduction Amounts to accomplish both of goals 1 and
2 above, the amounts thereof should be adjusted to so as to accomplish such goals within
the requirement that each Uncertificated Lower-Tier Regular Interest Y Principal Reduction
Amount must be less than or equal to the sum of (a) the Principal Realized Losses to be
allocated on the related Distribution Date for the related Loan Group remaining after the
allocation of such Realized Losses to the related class of ratio-strip principal only
certificates, if any, and (b) the remainder of the Pool Distribution Amount for the related
Loan Group or after reduction thereof by the distributions to be made on such Distribution
Date (i) to the related class of ratio-strip principal only certificates, if any, (ii) to
the related class of ratio-strip interest only certificates, if any, and (iii) in respect
of interest on the related Uncertificated Lower-Tier Regular Interests, or, if both of such
goals cannot be accomplished within such requirement, such adjustment as is necessary shall
be made to accomplish goal 1 within such requirement.  In the event of any conflict among
the provisions of the definition of Uncertificated Lower-Tier Regular Interest Y Principal
Reduction Amounts, such conflict shall be resolved on the basis of the goals and their
priorities set forth above within the requirement set forth in the preceding sentence.  If
the formula allocation of ΔY42 among ΔYk, ΔYl, ΔYm and ΔYn
cannot be achieved because one or more of ΔYk, ΔYl, ΔYm and ΔYn, as
so defined, is greater than the related one of ΔPk, ΔPl, ΔPm and
ΔPn, such an allocation shall be made as close as possible to the formula allocation
within the requirement that ΔYk < ΔPk, ΔYl < ΔPl, ΔYm <
ΔPm and ΔYn < ΔPn.

NOTES:

1.    Uncertificated Lower-Tier Regular Interests Y-AA and Z-AA are related to Loan Group
AA.  The sum of the Uncertificated Principal Balances of Uncertificated Lower-Tier Regular
Interests Y-AA and Z-AA is equal to the aggregate stated principal balance of the Mortgage
Loans in Loan Group AA.  Uncertificated Lower-Tier Regular Interests Y-BB and Z-BB are
related to Loan Group BB.  The sum of the Uncertificated Principal Balances of
Uncertificated Lower-Tier Regular Interests Y-BB and Z-BB is equal to the aggregate stated
principal balance of the Mortgage Loans in Loan Group BB.  Uncertificated Lower-Tier
Regular Interests Y-CC and Z-CC are related to Loan Group CC.  The sum of the
Uncertificated Principal Balances of Uncertificated Lower-Tier Regular Interests Y-CC and
Z-C is equal to the aggregate stated principal balance of the Mortgage Loans in Loan Group
CC.  Uncertificated Lower-Tier Regular Interests Y-DD and Z-DD are related to Loan Group
DD.  The sum of the Uncertificated Principal Balances of Uncertificated Lower-Tier Regular
Interests Y-DD and Z-D is equal to the aggregate stated principal balance of the Mortgage
Loans in Loan Group DD.  The Uncertificated Lower-Tier Regular Interests will be principal
and interest classes bearing interest at the pass-through rate for the related Loan Group.

                                        20

2.    The Class B pass-through rate is the weighted average of the pass-through rates on
the Uncertificated Lower-Tier Y Regular Interests.
