Such fee shall be payable monthly, computed on the basis of the same Stated Principal Balance and period respecting which any related interest payment on a BANA Mortgage Loan is computed.

Subservicer: Any Person that services Mortgage Loans on behalf of the Servicer or any Subservicer and is responsible for the performance (whether directly or through Subservicers or Subcontractors) of a substantial portion of the material servicing functions required to be performed by the Servicer under this Agreement or any reconstitution agreement that are identified in Item 1122(d) of Regulation AB. Subservicing Agreement: Any subservicing agreement (which, in the event the Subservicer is an affiliate of the Servicer, need not be in writing) between the -3- Servicer and any Subservicer relating to the servicing and/or administration of certain BANA Mortgage Loans as provided in Section 2.02. Except as otherwise specified herein or as the context may otherwise require, capitalized terms used but not otherwise defined herein are defined in the Pooling and Servicing Agreement. ARTICLE II ADMINISTRATION AND SERVICING OF MORTGAGE LOANS Section 2.01 Servicer to Service Mortgage Loans. For and on behalf of the Certificateholders, the Servicer shall service and administer the BANA Mortgage Loans in accordance with the terms of this Agreement, Customary Servicing Procedures, applicable law and the terms of the related Mortgage Notes and Mortgages. In connection with such servicing and administration, the Servicer shall have full power and authority, acting alone and/or through Subservicers as provided in Section 2.02, 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 Master Servicer, the Certificateholders, the Securities Administrator and the Trustee, customary consents or waivers and other instruments and documents, (b) to consent, with respect to the BANA Mortgage Loans, 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 BANA Mortgage Loans, and (d) to effectuate foreclosure or other conversion of the ownership of the Mortgaged Property securing any BANA Mortgage Loan. The 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 BANA Mortgage Loan and shall not make or permit any modification, waiver or amendment of any term of any BANA Mortgage Loan, except as provided pursuant to Section 2.20. Without limiting the generality of the foregoing, the Servicer, in its own name or in the name of any Subservicer or 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 and agreements of satisfaction, cancellation, default, assumption, modification, discharge, partial or full release, and all other comparable instruments and agreements, with respect to the BANA Mortgage Loans, and with respect to the related Mortgaged Properties held for the benefit of the Certificateholders. To the extent that the Servicer is not permitted to execute and deliver such documents pursuant to the preceding sentence, the 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 the Servicer to service and administer the BANA Mortgage Loans. Upon receipt of such documents, the Depositor and/or the Trustee, upon the direction of the Servicer, shall promptly execute such documents and deliver them to the Servicer. Alternatively, upon the request of the Servicer, the Trustee shall execute and deliver to the Servicer any additional powers of attorney or other documents prepared by the Servicer that are reasonably -4- necessary or appropriate to enable the Servicer to carry out its servicing and administrative duties under this Agreement. In accordance with the standards of the preceding paragraph, the Servicer shall advance or cause to be advanced funds as necessary for the purpose of effecting the payment of taxes and assessments on the Mortgaged Properties relating to the BANA Mortgage Loans, which Servicing Advances shall be reimbursable in the first instance from related collections from the Mortgagors pursuant to Section 2.08, and further as provided in Section 2.10. The costs incurred by the Servicer, if any, in effecting the timely payments of taxes and assessments on the Mortgaged Properties and related insurance premiums shall not, for the purpose of calculating monthly distributions to the Certificateholders, be added to the Stated Principal Balances of the BANA Mortgage Loans, notwithstanding that the terms of such BANA Mortgage Loans so permit. The relationship of the Servicer (and of any successor to the Servicer as servicer under this Agreement) to the Trustee, the Master Servicer and the Securities 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 2.02 Subservicing; Enforcement of the Obligations of Servicers. (a) The Servicer may arrange for the subservicing of any BANA Mortgage Loan 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 BANA 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 the Servicer and a Subservicer or reference to actions taken through a Subservicer or otherwise, the Servicer shall remain obligated and liable to the Depositor, the Master Servicer, the Securities Administrator, the Trustee and the Certificateholders for the servicing and administration of the BANA Mortgage Loans 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 the Servicer alone were servicing and administering those BANA Mortgage Loans. All actions of each Subservicer performed pursuant to the related Subservicing Agreement shall be performed as agent of the Servicer with the same force and effect as if performed directly by the Servicer. (b) For purposes of this Agreement, the Servicer shall be deemed to have received any collections, recoveries or payments with respect to the BANA Mortgage Loans that are received by a Subservicer regardless of whether such payments are remitted by the Subservicer to the Servicer. (c) As part of its servicing activities hereunder, the Servicer, for the benefit of the Trustee, the Securities Administrator, the Master Servicer and the Certificateholders, shall use its best reasonable efforts to enforce the obligations of each Subservicer engaged by the Servicer under the related Subservicing Agreement, to the extent that the non-performance of any such -5- obligation would have a material and adverse effect on a BANA 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 the Servicer, in its good faith business judgment, would require were it the owner of the related BANA Mortgage Loans. The 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 BANA 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 the Servicer shall provide that it may be assumed or terminated by the Master Servicer, if the Master Servicer has assumed the duties of the 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 Estate, upon the assumption by such party of the obligations of the Servicer pursuant to Section 5.02. (e) Any Subservicing Agreement, and any other transactions or services relating to the BANA Mortgage Loans involving a Subservicer, shall be deemed to be between the Servicer and such Subservicer alone, and the Trustee, the Securities Administrator, the Master Servicer and the Certificateholders shall not be deemed parties thereto and shall have no claims or rights of action against, rights, obligations, duties or liabilities to or with respect to the Subservicer or its officers, directors or employees, except as set forth in Section 2.01. The Servicer shall be solely liable for all fees owed by it to any Subservicer, irrespective of whether the Servicer's compensation pursuant to this Agreement is sufficient to pay such fees. Section 2.03 Fidelity Bond; Errors and Omissions Insurance. The Servicer shall maintain, at its own expense, a blanket fidelity bond and an errors and omissions insurance policy, with broad coverage on all officers, employees or other persons acting in any capacity requiring such persons to handle funds, money, documents or papers relating to the BANA Mortgage Loans. These policies must insure the Servicer against losses resulting from dishonest or fraudulent acts committed by the Servicer's personnel, any employees of outside firms that provide data processing services for the Servicer, and temporary contract employees or student interns. Such fidelity bond shall also protect and insure the Servicer against losses in connection with the release or satisfaction of a BANA Mortgage Loan without having obtained payment in full of the indebtedness secured thereby. No provision of this Section 2.03 requiring such fidelity bond and errors and omissions insurance shall diminish or relieve the Servicer from its duties and obligations as set forth in this Agreement. The minimum coverage under any such bond and insurance policy shall be at least equal to the corresponding amounts required by FNMA 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. -6- Section 2.04 Access to Certain Documentation. The Servicer shall provide to the OTS and the FDIC and to comparable regulatory authorities supervising Holders of 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 BANA 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 Servicer. Nothing in this Section 2.04 shall limit the obligation of the Servicer to observe any applicable law and the failure of the Servicer to provide access as provided in this Section 2.04 as a result of such obligation shall not constitute a breach of this Section 2.04. Section 2.05 Maintenance of Primary Mortgage Insurance Policy; Claims; Collections of BPP Mortgage Loan Payments. With respect to each BANA Mortgage Loan with a Loan-to-Value Ratio in excess of 80% or such other Loan-to-Value Ratio as may be required by law that was originated with a Primary Mortgage Insurance Policy, the Servicer shall, without any cost to the Trust Estate, maintain or cause the Mortgagor to maintain in full force and effect a Primary Mortgage Insurance Policy insuring that portion of the BANA Mortgage Loan in excess of a percentage in conformity with FNMA requirements. The 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 BANA Mortgage Loan is reduced to 80% or such other Loan-to-Value Ratio as may be required by law. If such Primary Mortgage Insurance Policy is terminated, the Servicer shall obtain from another insurer a comparable replacement policy, with a total coverage equal to the remaining coverage of such terminated Primary Mortgage Insurance Policy. If the insurer shall cease to be an insurer acceptable to FNMA, the Servicer shall notify the Master Servicer in writing, it being understood that the Servicer shall not have any responsibility or liability for any failure to recover under the Primary Mortgage Insurance Policy for such reason. If the Servicer determines that recoveries under the Primary Mortgage Insurance Policy are jeopardized by the financial condition of the insurer, the Servicer shall obtain from another insurer which meets the requirements of this Section 2.05 a replacement insurance policy. The Servicer shall not take any action that would result in noncoverage under any applicable Primary Mortgage Insurance Policy of any loss that, but for the actions of the Servicer, would have been covered thereunder. In connection with any assumption or substitution agreement entered into or to be entered into pursuant to Section 2.12, the Servicer shall promptly notify the insurer under the related Primary Mortgage Insurance Policy, if any, of such assumption or substitution of liability in accordance with the terms of such Primary Mortgage 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 Mortgage Insurance Policy. If such Primary Mortgage Insurance Policy is terminated as a result of such assumption or substitution of liability, the Servicer shall obtain a replacement Primary Mortgage Insurance Policy as provided above. In connection with its activities as servicer, the Servicer agrees to prepare and present, on behalf of itself, the Trust, the Trustee and the Certificateholders, claims to the insurer under any Primary Mortgage Insurance Policy in a timely fashion in accordance with the terms of such Primary Mortgage Insurance Policy and, in this regard, to take such action as shall be necessary -7- to permit recovery under any Primary Mortgage Insurance Policy respecting a defaulted BANA Mortgage Loan. Pursuant to Section 2.08(a), any amounts collected by the Servicer under any Primary Mortgage Insurance Policy shall be deposited in the Escrow Account, subject to withdrawal pursuant to Section 2.08(b). The 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 Mortgage 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. The Servicer shall take all actions necessary to collect, on behalf of the Trust, any BPP Mortgage Loan Payments required to be made to the Trust pursuant to the Mortgage Loan Purchase Agreement. Section 2.06 Master Servicer to Act as Servicer. If the Servicer shall for any reason no longer be the Servicer hereunder (including by reason of an Event of Default), the Master Servicer shall within 90 days of such time, assume, if it so elects, or shall appoint a successor Servicer to assume, all of the rights and obligations of the Servicer hereunder arising thereafter (except that the Master Servicer shall not be (a) liable for losses of the Servicer pursuant to Section 2.11 or any acts or omissions of the predecessor Servicer hereunder, (b) obligated to make Advances if it is prohibited from doing so by applicable law or (c) deemed to have made any representations and warranties of the Servicer hereunder). Any such assumption shall be subject to Sections 4.02 and 5.02. If the Servicer shall for any reason no longer be the Servicer (including by reason of any Event of Default), the Master Servicer or the successor Servicer may elect to succeed to any rights and obligations of the Servicer under each Subservicing Agreement or may terminate each Subservicing Agreement. If it has elected to assume the Subservicing Agreement, the Master Servicer or the successor Servicer shall be deemed to have assumed all of the Servicer's interest therein and to have replaced the Servicer as a party to any Subservicing Agreement entered into by the Servicer as contemplated by Section 2.02 to the same extent as if the Subservicing Agreement had been assigned to the assuming party except that the Servicer shall not be relieved of any liability or obligations under any such Subservicing Agreement. The Servicer that is no longer a Servicer hereunder shall, upon request of the Master Servicer, but at the expense of such Servicer, deliver to the assuming party all documents and records relating to each Subservicing Agreement or substitute servicing agreement and the BANA Mortgage Loans then being serviced thereunder and an accounting of amounts collected or held by it and otherwise use its best efforts to effect the orderly and efficient transfer of such substitute Subservicing Agreement to the assuming party. The Master Servicer shall be entitled to be reimbursed from such Servicer (or the Trust if such Servicer is unable to fulfill its obligations hereunder) for all Servicing Transfer Costs. Section 2.07 Collection of Mortgage Loan Payments and BANA Custodial Account. (a) Continuously from the date hereof until the principal and interest on all BANA Mortgage Loans are paid in full, the Servicer will proceed diligently, in accordance with this Agreement, to collect all payments due under each of the -8- BANA Mortgage Loans when the same shall become due and payable. Further, the Servicer will in accordance with all applicable law and Customary Servicing Procedures ascertain and estimate taxes, assessments, fire and hazard insurance premiums, mortgage insurance premiums and all other charges with respect to the BANA Mortgage Loans 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, the Servicer may in its discretion (i) waive any late payment charge or any prepayment penalties or penalty interest in connection with the prepayment of a BANA Mortgage Loan and (ii) extend the due dates for payments due on a Mortgage Note for a period not greater than 120 days; provided, however, that the Servicer cannot extend the maturity of any such BANA Mortgage Loan past the date on which the final payment is due on the latest maturing BANA Mortgage Loan as of the Cut-Off Date. In the event of any such arrangement, the Servicer shall make Monthly Advances on the related BANA Mortgage Loan in accordance with the provisions of Section 2.19 during the scheduled period without modification thereof by reason of such arrangements. The Servicer shall not be required to institute or join in litigation with respect to collection of any payment (whether under a Mortgage, Mortgage Note or otherwise or against any public or governmental authority with respect to a taking or condemnation) if it reasonably believes that enforcing the provision of the Mortgage or other instrument pursuant to which such payment is required is prohibited by applicable law. (b) The Servicer shall establish and maintain the BANA Custodial Account. The Servicer shall deposit or cause to be deposited into the BANA Custodial Account on a daily basis within one Business Day of receipt, except as otherwise specifically provided herein, the following payments and collections remitted by Subservicers or received by it in respect of the BANA Mortgage Loans subsequent to the Cut-Off Date (other than in respect of principal and interest due on the BANA Mortgage Loans on or before the Cut-Off Date) and the following amounts required to be deposited hereunder with respect to the BANA Mortgage Loans it services: (i) all payments on account of principal of such BANA Mortgage Loans, including Principal Prepayments; (ii) all payments on account of interest on such BANA 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 or (3) required to be deposited to the Escrow Account pursuant to Section 2.08(a), and other than any Excess Proceeds and (B) any Insurance Proceeds released from the Escrow Account pursuant to Section 2.08(b)(iv); (iv) any amount required to be deposited by the Servicer pursuant to Section 2.07(d) in connection with any losses on Permitted Investments with respect to the BANA Custodial Account; -9- (v) any amounts required to be deposited by the Servicer pursuant to Section 2.13; (vi) all Repurchase Prices, all Substitute Adjustment Amounts, all Reimbursement Amounts and all Recoveries to the extent received by the Servicer; (vii) Monthly Advances made by the Servicer pursuant to Section 2.19 and any Compensating Interest; and (viii) any other amounts required to be deposited hereunder. The foregoing requirements for deposits to the BANA Custodial Account by the Servicer shall be exclusive. If the Servicer shall deposit in the BANA Custodial Account any amount not required to be deposited, it may at any time withdraw or direct the institution maintaining the BANA Custodial Account to withdraw such amount from the BANA Custodial Account, any provision herein to the contrary notwithstanding. The BANA 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 the Servicer or serviced by the Servicer on behalf of others; provided, however, that such commingling of funds shall not be permitted at any time during which Fitch's senior long-term unsecured debt rating of Bank of America, National Association is below "A." Notwithstanding such commingling of funds, the Servicer shall keep records that accurately reflect the funds on deposit in the BANA Custodial Account that have been identified by it as being attributable to the BANA Mortgage Loans. The Servicer shall maintain adequate records with respect to all withdrawals made pursuant to this Section 2.07. All funds required to be deposited in the BANA Custodial Account shall be held in trust for the Certificateholders until withdrawn in accordance with Section 2.10. (c) The institution at which the BANA Custodial Account is maintained may invest the funds therein as directed in writing by the 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). All such Permitted Investments shall be made in the name of the Trustee, for the benefit of the Certificateholders. All BANA Custodial Account Reinvestment Income shall be for the benefit of the Servicer as part of its Servicing Compensation and shall be retained by it monthly as provided herein. The amount of any losses realized in the BANA Custodial Account incurred in respect of any such investments shall promptly be deposited by the Servicer in the BANA Custodial Account. (d) The Servicer shall give notice to the Master Servicer of any proposed change of the location of the BANA Custodial Account maintained by it not later than 30 days and not more than 45 days prior to any change thereof. The creation of the BANA Custodial Account shall be evidenced by a certification substantially in the form of Exhibit A hereto. A copy of such certification shall be furnished to the Master Servicer. -10- Section 2.08. Collection of Taxes, Assessments and Similar Items; Escrow Account. (a) To the extent required by the related Mortgage Note and not violative of current law, the Servicer shall segregate and hold all funds collected and received pursuant to each BANA 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 Account"), titled "Bank of America, National Association, in trust for registered holders of Banc of America Funding Corporation Mortgage Pass-Through Certificates, Series 2007-4 and various Mortgagors." The 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, the Escrow Account shall be insured by the FDIC to the fullest extent permitted by law. The Servicer shall deposit in the appropriate Escrow Account on a daily basis, and retain therein: (i) all Escrow Payments collected on account of the BANA 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 Mortgage Insurance Policy. Nothing herein shall require the Servicer to compel a Mortgagor to establish an Escrow Account in violation of applicable law. (b) Withdrawals of amounts so collected from the Escrow Account may be made by the 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 BANA Mortgage Loan for any Servicing Advance made by the Servicer pursuant to Section 2.08(c) with respect to such BANA Mortgage Loan, (iii) to refund to any Mortgagor any sums determined to be overages, (iv) for transfer to the BANA Custodial Account upon default of a Mortgagor or in accordance with the terms of the related BANA 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, any interest paid on the funds deposited in the Escrow Account, (vii) to pay to itself any interest earned on funds deposited in the Escrow Account (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 the Escrow Account, (x) to withdraw any amounts inadvertently deposited in the Escrow Account; or (xi) to clear and terminate the Escrow Account upon the termination of this Agreement in accordance with Section 6.01. Any Escrow Account shall not be a part of the Trust Estate. (c) With respect to each BANA Mortgage Loan, the 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 Mortgage Insurance Policy premiums and fire and hazard insurance coverage. The 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 the Servicer in amounts sufficient for such -11- purposes, as allowed under the terms of the Mortgage. To the extent that a Mortgage does not provide for Escrow Payments, the Servicer shall determine that any such payments are made by the Mortgagor. The 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. The Servicer shall advance any such payments that are not timely paid, but the Servicer shall be required so to advance only to the extent that such Servicing Advances, in the good faith judgment of the Servicer, will be recoverable by the Servicer out of Insurance Proceeds, Liquidation Proceeds or otherwise. Section 2.09. Access to Certain Documentation and Information Regarding the Mortgage Loans. The Servicer shall afford the Master Servicer, the Securities Administrator and the Trustee reasonable access to all records and documentation regarding the BANA Mortgage Loans serviced by it 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 the Servicer. Section 2.10. Permitted Withdrawals from the BANA Custodial Account. The Servicer may from time to time make withdrawals from the BANA Custodial Account, for the following purposes: (i) to pay itself (to the extent not previously retained), the Servicing Compensation to which it is entitled pursuant to Section 2.16; (ii) to reimburse itself for unreimbursed Advances made by it, such right of reimbursement pursuant to this clause (ii) being limited to amounts received on the BANA Mortgage Loans (including amounts received in respect of BPP Mortgage Loan Payments for such BANA Mortgage Loans) in respect of which any such Advance was made; (iii) to reimburse itself for any Nonrecoverable Advance previously made; (iv) to reimburse itself for Insured Expenses from the Insurance Proceeds; (v) to pay to the purchaser, with respect to each BANA Mortgage Loan or REO Property that has been purchased pursuant to the Pooling and Servicing Agreement, all amounts received thereon after the date of such purchase; (vi) to reimburse itself or the Depositor for expenses incurred by any of them and reimbursable pursuant to Section 4.03; (vii) to withdraw any amount deposited in the BANA Custodial Account and not required to be deposited therein; -12- (viii) on or prior to the Remittance Date, to withdraw an amount equal to the portion of the Pool Distribution Amount relating to the BANA Mortgage Loans and any other amounts due to the Master Servicer under this Agreement for such Distribution Date, to the extent on deposit, and remit such amount in immediately available funds to the Master Servicer for deposit in the Master Servicer Custodial Account; (ix) on or prior to the Remittance Date, to withdraw all amounts deposited into the BANA Custodial Account pursuant to Section 2.07(b)(viii) for such Distribution Date and remit such amounts in immediately available funds to the Master Servicer for deposit into the Master Servicer Custodial Account; and (x) to clear and terminate the BANA Custodial Account upon termination of this Agreement pursuant to Section 6.01. The Servicer shall keep and maintain separate accounting, on a BANA Mortgage Loan by BANA Mortgage Loan basis, for the purpose of justifying any withdrawal from the BANA Custodial Account pursuant to clauses (i), (ii), (iv) and (v) above. Prior to making any withdrawal from the BANA Custodial Account pursuant to clause (iii) above, the Servicer shall deliver to the Master Servicer an Officer's Certificate of a Servicing Officer indicating the amount of any previous Advance determined by the Servicer to be a Nonrecoverable Advance and identifying the related BANA Mortgage Loan(s) and their respective portions of such Nonrecoverable Advance. In connection with any failure by the Servicer to make any remittance required to be made by it to the Master Servicer Custodial Account on the day and by the time such remittance is required to be made under this Agreement (without giving effect to any grace or cure period), the Servicer shall pay the Master Servicer for the account of the Master Servicer interest at the rate published in The Wall Street Journal as the "Prime Rate" on any amount not timely remitted from and including the day such remittance was required to be made to, but not including, the day on which such remittance was actually made. Section 2.11. Maintenance of Hazard Insurance. The Servicer shall cause to be maintained for each BANA Mortgage Loan 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 BANA 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 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. The Servicer shall also maintain on REO Property serviced by it, 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 the Servicer -13- 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 BANA Mortgage Loan, or to be released to the Mortgagor in accordance with Customary Servicing Procedures) shall be deposited in the BANA Custodial Account, subject to withdrawal pursuant to Section 2.10. It is understood and agreed that no earthquake or other additional insurance need be required by the 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 Servicer, and shall provide for at least 30 days prior written notice of any cancellation, reduction in amount or material change in coverage to the Servicer. The hazard insurance policies for each BANA Mortgage Loan secured by a unit in a condominium development or planned unit development shall be maintained with respect to such BANA Mortgage Loan and the related development in a manner which is consistent with FNMA requirements. Notwithstanding the foregoing, the Servicer may maintain a blanket policy insuring against hazard losses on all of the Mortgaged Properties relating to the BANA Mortgage Loans in lieu of maintaining the required hazard insurance policies for each BANA 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 Servicer as loss payee, (C) provide coverage in an amount equal to the aggregate unpaid principal balance on the related BANA Mortgage Loans without co-insurance, and (D) otherwise comply with the requirements of this Section 2.11. 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 2.11 and a loss occurs with respect to such Mortgaged Property which loss would have been covered by such a policy, the Servicer shall deposit in the BANA Custodial Account the difference, if any, between the amount that would have been payable under a separate policy complying with this Section 2.11 and the amount paid under such blanket policy. Section 2.12. Enforcement of Due-On-Sale Clauses; Assumption Agreements. (a) Except as otherwise provided in this Section 2.12, when any Mortgaged Property subject to a Mortgage has been conveyed by the Mortgagor, the Servicer shall use reasonable efforts, to the extent that it has actual knowledge of such conveyance, to enforce any due-on-sale clause contained in any Mortgage Note or Mortgage, to the extent permitted under applicable law and governmental regulations, but only to the extent that such enforcement will not adversely affect or jeopardize coverage under any Required Insurance Policy. Notwithstanding the foregoing, the Servicer is not required to exercise such rights with respect to a Mortgage Loan if the Person to whom the related Mortgaged Property has been conveyed or is proposed to be conveyed satisfies the terms and conditions contained in the Mortgage Note and Mortgage related thereto and the consent of the mortgagee under such Mortgage Note or Mortgage is not otherwise required under such Mortgage Note or Mortgage as a condition to such transfer. If (i) the Servicer is prohibited by law from enforcing any such due-on-sale clause, (ii) coverage under any Required Insurance Policy would be adversely affected, (iii) the Mortgage Note does not include a due-on-sale -14- clause or (iv) nonenforcement is otherwise permitted hereunder, the Servicer is authorized, subject to Section 2.12(b), to take or enter into an assumption and modification agreement from or with the Person to whom such Mortgaged Property has been or is about to be conveyed, pursuant to which such Person becomes liable under the Mortgage Note and, unless prohibited by applicable state law, the Mortgagor remains liable thereon; provided that the BANA Mortgage Loan shall continue to be covered (if so covered before the Servicer enters such agreement) by the applicable Required Insurance Policies. The Servicer, subject to Section 2.12(b), is also authorized with the prior approval of the insurers under any Required Insurance Policies to enter into a substitution of liability agreement with such Person, pursuant to which the original Mortgagor is released from liability and such Person is substituted as Mortgagor and becomes liable under the Mortgage Note. Notwithstanding the foregoing, the Servicer shall not be deemed to be in default under this Section 2.12 by reason of any transfer or assumption which it reasonably believes it is restricted by law from preventing, for any reason whatsoever. (b) Subject to the Servicer's duty to enforce any due-on-sale clause to the extent set forth in Section 2.12(a), in any case in which a Mortgaged Property has been conveyed to a Person by a Mortgagor, and such Person is to enter into an assumption agreement or modification agreement or supplement to the Mortgage Note or Mortgage or if an instrument of release is required releasing the Mortgagor from liability on the BANA Mortgage Loan, the Servicer shall prepare and execute the assumption agreement with the Person to whom the Mortgaged Property is to be conveyed and such modification agreement or supplement to the Mortgage Note or Mortgage or other instruments as are reasonable or necessary to carry out the terms of the Mortgage Note or Mortgage or otherwise to comply with any applicable laws regarding assumptions or the transfer of the Mortgaged Property to such Person. In connection with any such assumption, no material term of the Mortgage Note may be changed. In addition, the substitute Mortgagor and the Mortgaged Property must be acceptable to the Servicer in accordance with its underwriting standards as then in effect. Together with each such substitution, assumption or other agreement or instrument, the Servicer shall execute an Officer's Certificate signed by a Servicing Officer stating that the requirements of this subsection have been met. The Servicer shall notify the Master Servicer and the Trustee that any such substitution or assumption agreement has been completed by forwarding to the Master Servicer, who shall forward to the Trustee (or at the direction of the Trustee, the Custodian) a copy of the Officer's Certificate described in the previous sentence and the original of such substitution or assumption agreement, which in the case of the original shall be added to the related Mortgage File and shall, for all purposes, be considered a part of such Mortgage File to the same extent as all other documents and instruments constituting a part thereof. Any fee collected by the Servicer for entering into an assumption or substitution of liability agreement may be retained by it as additional servicing compensation. Section 2.13. Realization Upon Defaulted Mortgage Loans; REO Property. The Servicer shall use reasonable efforts to foreclose upon or otherwise comparably convert the ownership of Mortgaged Properties securing such of the BANA Mortgage Loans as come into and continue in default and as to which no satisfactory arrangements can be made for collection of delinquent payments. In connection with such foreclosure or other conversion, the Servicer shall follow Customary Servicing Procedures and shall meet the requirements of the insurer -15- under any Required Insurance Policy. Notwithstanding the foregoing, a Servicer shall not 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 BANA 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 BANA Mortgage Loan (respecting which it shall have priority for purposes of withdrawals from the BANA Custodial Account). Any such expenditures shall constitute Servicing Advances for purposes of this Agreement. With respect to any REO Property, the deed or certificate of sale shall be taken in the name of the Trust for the benefit of the Certificateholders, or its nominee, on behalf of the Certificateholders. The name of the Trust shall be placed on the title to such REO Property. The Servicer shall ensure that the title to such REO Property references this Agreement. Pursuant to its efforts to sell such REO Property, the Servicer shall either itself or through an agent selected by it 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, the Servicer may rent the same, or any part thereof, as it deems to be in the best interest of the Certificateholders for the period prior to the sale of such REO Property. The Servicer shall prepare for and deliver to the Master Servicer a statement with respect to each REO Property serviced by it 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 Securities Administrator to comply with the reporting requirements of the REMIC Provisions; provided, however, that the Servicer shall have no 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 BANA Custodial Account no later than the close of business on each Determination Date. The Servicer shall perform, with respect to the BANA 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. If the Trust acquires any Mortgaged Property as described above or otherwise in connection with a default or a default which is reasonably foreseeable on a BANA Mortgage Loan, the Servicer shall dispose of such Mortgaged Property prior to the end of the third calendar year following the year of its acquisition by the Trust (such period, the "REO Disposition Period") unless (A) the Master Servicer, the Securities Administrator, on behalf of the Trustee, and the Trustee shall have been supplied by the Servicer with an Opinion of Counsel to the effect that the holding by the Trust of such Mortgaged Property subsequent to the REO Disposition Period will not result in the imposition of taxes on "prohibited transactions" (as defined in Section 860F of the Code) on any REMIC or cause any REMIC Estate to fail to qualify as a separate REMIC at any time that any Certificates are outstanding, or (B) the Master Servicer, on behalf of the Trustee (at the Servicer's expense), or the Servicer shall have applied for, prior to the expiration of the REO Disposition Period, an extension of the REO Disposition Period in the manner contemplated by -16- Section 856(e)(3) of the Code. If such an Opinion of Counsel is provided or such an exemption is obtained, the Trust may continue to hold such Mortgaged Property (subject to any conditions contained in such Opinion of Counsel) for the applicable period. Notwithstanding any other provision of this Agreement, no Mortgaged Property acquired by the Trust shall be rented (or allowed to continue to be rented) or otherwise used for the production of income by or on behalf of the Trust in such a manner or pursuant to any terms that would (i) cause such Mortgaged Property to fail to qualify as "foreclosure property" within the meaning of Section 860G(a)(8) of the Code or (ii) subject any REMIC to the imposition of any federal, state or local income taxes on the income earned from such Mortgaged Property under Section 860G(c) of the Code or otherwise, unless the Servicer has agreed to indemnify and hold harmless the Trust with respect to the imposition of any such taxes. The Servicer shall identify to the Master Servicer and the Securities Administrator any Mortgaged Property relating to a BANA Mortgage Loan held by the Trust for 30 months for which no plans to dispose of such Mortgaged Property by the Servicer have been made. After delivery of such identification, the Servicer shall proceed to dispose of any such Mortgaged Property by holding a commercially reasonable auction for such property. The income earned from the management of any REO Properties, net of reimbursement to the Servicer for expenses incurred (including any property or other taxes) in connection with such management and net of unreimbursed Servicing Fees, Monthly Advances and Servicing Advances, shall be applied to the payment of principal of and interest on the related defaulted BANA Mortgage Loans (solely for the purposes of allocating principal and interest, interest shall be treated as accruing as though such BANA 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 BANA 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 BANA Mortgage Loan for such calendar month, such excess shall be considered to be a partial prepayment of principal of the related BANA Mortgage Loan. The proceeds from any liquidation of a BANA Mortgage Loan, as well as any income from an REO Property, will be applied in the following order of priority: first, to reimburse the Servicer for any related unreimbursed Servicing Advances and Servicing Fees; second, to reimburse the Servicer for any unreimbursed Monthly Advances and to reimburse the BANA Custodial Account for any Nonrecoverable Advances (or portions thereof) that were previously withdrawn by the Servicer pursuant to Section 2.10(iii) that related to such BANA Mortgage Loan; third, to accrued and unpaid interest (to the extent no Monthly Advance has been made for such amount or any such Monthly Advance has been reimbursed) on the BANA Mortgage Loan or related REO Property, at the Mortgage Rate to the Due Date occurring in the month in which such amounts are required to be distributed; and fourth, as a recovery of principal of the BANA 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 2.16. -17- Section 2.14. Trustee to Cooperate; Release of Mortgage Files. Upon the payment in full of any BANA Mortgage Loan, or the receipt by the Servicer of a notification that payment in full will be escrowed in a manner customary for such purposes, the Servicer or the Master Servicer will immediately notify the Trustee (or, at the direction of the Trustee, the Custodian) by delivering, or causing to be delivered, two copies (one of which will be returned to the Servicer with the Mortgage File of a Request for Release (which may be delivered in an electronic format acceptable to the Trustee and the Servicer or the Master Servicer). Upon receipt of such request, the Trustee or the Custodian, as applicable, shall within seven Business Days release the related Mortgage File to the Servicer. The Trustee shall deliver to the Servicer the Mortgage Note with written evidence of cancellation thereon. If the Mortgage has been recorded in the name of MERS or its designee, the Servicer shall take all necessary action to reflect the release of the Mortgage on the records of MERS. 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 BANA Mortgage Loan, including for such purpose collection under any policy of flood insurance, any fidelity bond or errors or omissions policy, or for the purposes of effecting a partial release of any Mortgaged Property from the lien of the Mortgage or the making of any corrections to the Mortgage Note or the Mortgage or any of the other documents included in the Mortgage File, the Trustee or the Custodian, as applicable, shall, upon delivery to the Trustee (or, at the direction of the Trustee, the Custodian) of a Request for Release signed by a Servicing Officer, release the Mortgage File within seven Business Days to the Servicer. Subject to the further limitations set forth below, the Servicer shall cause the Mortgage File so released to be returned to the Trustee or the Custodian, as applicable, when the need therefor by the Servicer no longer exists, unless the BANA Mortgage Loan is liquidated and the proceeds thereof are deposited in the BANA Custodial Account, in which case the Servicer shall deliver to the Trustee or the Custodian, as applicable, a Request for Release, signed by a Servicing Officer. Upon prepayment in full of any BANA Mortgage Loan or the receipt of notice that funds for such purpose have been placed in escrow, the Servicer shall give an instrument of satisfaction (or Assignment of Mortgage without recourse) regarding the Mortgaged Property relating to such BANA 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, the Servicer shall take all necessary action to reflect the release on the records of MERS. In lieu of executing such satisfaction or Assignment of Mortgage, or if another document is required to be executed by the Trustee, the 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 such foreclosure or any legal action brought to obtain judgment against the Mortgagor on the Mortgage Note or the Mortgage or to obtain a deficiency judgment or to enforce any other remedies or rights provided by the Mortgage Note or the Mortgage or otherwise available at law or in equity. -18- Section 2.15. Documents, Records and Funds in Possession of the Servicer to be Held for the Trustee. The Servicer shall transmit to the Trustee or, at the direction of the Trustee, the Custodian, as required by this Agreement all documents and instruments in respect of a BANA Mortgage Loan serviced by it coming into the possession of the Servicer from time to time and shall account fully to the Trustee for any funds received by the Servicer or which otherwise are collected by the Servicer as Liquidation Proceeds or Insurance Proceeds in respect of any BANA Mortgage Loan. The documents constituting the Servicing File shall be held by the Servicer as custodian and bailee for the Trustee. All Mortgage Files and funds collected or held by, or under the control of, the Servicer in respect of any BANA 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 BANA Custodial Account, shall be held by the Servicer for and on behalf of the Trustee and shall be and remain the sole and exclusive property of the Trustee, subject to the applicable provisions of this Agreement. The Servicer also agrees that it shall not knowingly create, incur or subject any Mortgage File or any funds that are deposited in the BANA Custodial Account, Master Servicer Custodial 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 the 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 BANA Mortgage Loan, except, however, that the Servicer shall be entitled to set off against and deduct from any such funds any amounts that are properly due and payable to the Servicer under this Agreement. Section 2.16. Servicing Compensation. The Servicer shall be entitled out of each payment of interest on a BANA Mortgage Loan (or portion thereof) included in the Trust Estate to retain or withdraw from the BANA 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 the related Servicer to the extent not required to be deposited in the related BANA Custodial Account pursuant to Section 2.07(b). The 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 the 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 BANA Mortgage Loans serviced by such Servicer and (b) one-twelfth of 0.25% of the aggregate Stated Principal Balance of such BANA Mortgage Loans for such Distribution Date (any such reduction, "Compensating Interest"). -19- Section 2.17. Annual Statement as to Compliance. The Servicer shall deliver to the Master Servicer and the Depositor (and the Master Servicer will forward to the Trustee, the Securities Administrator and each Rating Agency), no later than March 5 following the end of each calendar year commencing with March 2008, an Officer's Certificate in the form required by Item 1123 of Regulation AB, to the effect that (i) an authorized officer of the Servicer has reviewed (or a review has been made under his or her supervision of) the Servicer's activities under this Agreement during the prior calendar year and (ii) to the best of such officer's knowledge, based on such review, the Servicer has fulfilled all its obligations under this Agreement in all material respects throughout such year, or, if there has been a default in the fulfillment of any such obligation in any material respect, specifying each such default known to such officer and the nature and status thereof. Section 2.18. Annual Independent Public Accountants' Servicing Statement; Financial Statements; Provision of Additional Information. On or before March 5 of each calendar year, commencing in 2008, the Servicer shall: (a) deliver to the Master Servicer and the Depositor a report (in form and substance reasonably satisfactory to the Master Servicer and the Depositor) regarding the Servicer's assessment of compliance with the Servicing Criteria during the immediately preceding calendar year, as required under Rules 13a-18 and 15d-18 of the Exchange Act and Item 1122 of Regulation AB. Such report shall be addressed to the Master Servicer and the Depositor and signed by an authorized officer of the Servicer, and shall address each of the "Applicable Servicing Criteria" specified on Exhibit E hereto; (b) Not later than March 5th of each calendar year, following the end of each calendar year commencing with March 2008, the Servicer, at its expense, shall cause a registered public accounting firm which is a member of the institute of certified public accountants to furnish to the Master Servicer and the Depositor a report by such accounting firm that attests to, and reports on, the assessment made by the Servicer pursuant to this Section 2.18, as required by Rules 13a-18 and 15d-18 under the Exchange Act, and Item 1122(b) of Regulation AB. Such attestation shall be in accordance with Rule 1-02(a)(3) and Rule 2-02(g) of Regulation S-X under the Securities Act and the Exchange Act; (c) cause each Subservicer, and each Subcontractor determined by the Servicer pursuant to Section 2.02 to be "participating in the servicing function" within the meaning of Item 1122 of Regulation AB and deliver to the Master Servicer and the Depositor an assessment of compliance and accountants' attestation as and when provided in paragraphs (a) and (b) of this Section; and (d) with respect to any year in which a certification under the Sarbanes-Oxley Act of 2002, as amended, is required to be given with respect to the Trust Fund, deliver, or cause each Subservicer and Subcontractor described in Section 2.18(c) to provide, to the Depositor, the Master Servicer and any other Person that will be responsible for signing the certification (a "Sarbanes Certification") required by Rules 13a-14(d) and 15d-14(d) under the Exchange Act (pursuant to Section 302 of the Sarbanes-Oxley Act of 2002) on behalf of an -20- asset-backed issuer with respect to a Securitization Transaction a certification, signed by the appropriate officer of the Servicer, in the form attached hereto as Exhibit B. In addition, the Servicer shall indemnify and hold harmless the Master Servicer and the Depositor and their officers, directors and affiliates from and against any losses, damages, penalties, fines, forfeitures, reasonable and necessary legal fees and related costs, judgments and other costs and expenses arising out of or based upon any inaccuracy in the certification provided by it pursuant to Section 2.18(c), any breach of its obligations under Section 2.17 and Section 2.18 or its negligence, bad faith or willful misconduct in connection therewith. If the indemnification provided for herein is unavailable or insufficient to hold harmless the Master Servicer, the Depositor and their respective officers, directors and affiliates, then the Servicer agrees that it shall contribute to the amount paid or payable by the Master Servicer or the Depositor and their respective officers, directors or affiliates as a result of the losses, claims, damages or liabilities of the Master Servicer or the Depositor and their respective officers, directors and affiliates in such proportion as is appropriate to reflect the relative fault of the Master Servicer or the Depositor and their respective officers, directors and affiliates on the one hand and such Servicer on the other in connection with a breach of its obligations under Section 2.17 or Section 2.18 or its negligence, bad faith or willful misconduct in connection therewith. The obligations set forth in paragraphs (c) and (d) shall only apply with respect to periods for which reports on Form 10-K will be filed for the Trust Fund. Section 2.19. Advances. The Servicer shall determine on or before each Determination Date whether it is required to make a Monthly Advance pursuant to the definition thereof. If the Servicer determines it is required to make a Monthly Advance, it shall, on or before the Remittance Date, either (a) deposit into the BANA Custodial Account an amount equal to the Advance and/or (b) make an appropriate entry in its records relating to the BANA Custodial Account that any portion of the Amount Held for Future Distribution in the BANA Custodial Account has been used by the Servicer in discharge of its obligation to make any such Monthly Advance. Any funds so applied shall be replaced by the Servicer by deposit in the BANA Custodial Account no later than the close of business on the Business Day preceding the next Remittance Date. The Servicer shall be entitled to be reimbursed from the BANA Custodial Account for all Advances of its own funds made pursuant to this Section 2.19 as provided in Section 2.10. The obligation to make Monthly Advances with respect to any BANA Mortgage Loan shall continue until the ultimate disposition of the REO Property or Mortgaged Property relating to such BANA Mortgage Loan. The Servicer shall inform the Master Servicer and the Securities Administrator of the amount of the Monthly Advance to be made by it no later than the related Remittance Date. The Servicer shall deliver to the Master Servicer and the Securities Administrator on the Determination Date an Officer's Certificate of a Servicing Officer indicating the amount of any proposed Monthly Advance determined by the Servicer to be a Nonrecoverable Advance. Notwithstanding anything to the contrary, the Servicer shall not be required to make any Monthly Advance or Servicing Advance that would be a Nonrecoverable Advance. -21- Section 2.20. Modifications, Waivers, Amendments and Consents. (a) Subject to this Section 2.20, the Servicer may agree to any modification, waiver, forbearance, or amendment of any term of any BANA Mortgage Loan without the consent of the Master Servicer, the Securities Administrator, the Trustee or any Certificateholder. All modifications, waivers, forbearances or amendments of any BANA Mortgage Loan shall be in writing and shall be consistent with Customary Servicing Procedures. (b) The Servicer shall not agree to enter into, and shall not enter into, any modification, waiver (other than a waiver referred to in Section 2.12, which waiver, if any, shall be governed by Section 2.12), forbearance or amendment of any term of any BANA 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; (ii) in the Servicer's judgment, materially impair the security for such BANA Mortgage Loan or reduce the likelihood of timely payment of amounts due thereon; or (iii) otherwise constitute a "significant modification" within the meaning of Treasury Regulations Section 1.860G-2(b); unless, in either case, (A) such BANA Mortgage Loan is 90 days or more past due or (B) the Servicer delivers to the Master Servicer and the Securities Administrator an Opinion of Counsel to the effect that such modification, waiver, forbearance or amendment would not affect the REMIC status of any REMIC and, in either case, such modification, waiver, forbearance or amendment is reasonably likely to produce a greater recovery with respect to such BANA Mortgage Loan than would liquidation. Notwithstanding the foregoing, no Opinion of Counsel need be delivered if the purpose of the modification is to reduce the Monthly Payment on a Mortgage Loan as a result of a partial Principal Prepayment provided that the Mortgage Loan is fully amortized by its original maturity date. Subject to Customary Servicing Procedures, the Servicer may permit a forbearance for a BANA Mortgage Loan which in the Servicer's judgment is subject to imminent default. (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 BANA Mortgage Loan, notwithstanding that the terms of such BANA Mortgage Loan or such modification, waiver or amendment so permit. (d) The Servicer may, as a condition to granting any request by a Mortgagor for consent, modification, waiver, forbearance or amendment, the granting of which is within the Servicer's discretion pursuant to the BANA Mortgage Loan and is permitted by the terms of this Agreement, require that such Mortgagor pay to the 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 it, which amount shall be retained by the Servicer as additional servicing compensation. -22- (e) The Servicer shall notify the Master Servicer, in writing, of any modification, waiver, forbearance or amendment of any term of any BANA Mortgage Loan and the date thereof, and shall deliver to the Trustee (or, at the direction of the Trustee, the Custodian) for deposit in the related Mortgage File, an original counterpart of the agreement relating to such modification, waiver, forbearance or amendment, promptly (and in any event within ten Business Days) following the execution thereof; provided, however, that if any such modification, waiver, forbearance or amendment is required by applicable law to be recorded, the Servicer (i) shall deliver to the Trustee (or, at the direction of the Trustee, the Custodian) a copy thereof and (ii) shall deliver to the Trustee (or, at the direction of the Trustee, the Custodian) such document, with evidence of notification upon receipt thereof from the public recording office.

(b) The Servicer hereby agrees to reasonably cooperate to enable the Trust to fully comply with all Securities and Exchange Commission ("SEC") disclosure and reporting requirements in effect from time to time with respect to the Trust and any securities representing ownership interests in or backed by assets of the Trust, including without limitation, Regulation AB. (c) The Servicer hereby acknowledges and agrees that the Depositor, the Master Servicer and the Securities Administrator are relying on its performance of its obligations under Sections 2.17 and 2.18 in order to perform their respective obligations under Section 3.22 of the Pooling and Servicing Agreement.

Upon request, the Servicer shall provide to the Master Servicer and the Depositor evidence of the authorization of the person signing any certification or statement, copies or other evidence of Fidelity Bond Insurance and Errors and Omission Insurance policy, financial information and reports, and such other information related to the Servicer or any Subservicer or the Servicer or such Subservicer's performance hereunder.

Any Person into which the Servicer may be merged or consolidated, or any corporation resulting from any merger or consolidation to which the Servicer shall be a party, or any Person succeeding to the business of the Servicer, shall be the successor of the Servicer, 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 Servicer shall be qualified to service mortgage loans on behalf of FNMA or FHLMC.

The Servicer shall not 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 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 Servicer shall be entitled to be reimbursed therefor out of amounts attributable to the BANA Mortgage Loans on deposit in the BANA Custodial Account as provided by Section 2.10. Section 4.04. Servicer Not to Resign; Transfers of Servicing. (a) Subject to the provisions of Section 4.02, the Servicer shall not resign from its obligations and duties hereby imposed on it except upon determination that its duties hereunder are no longer permissible under applicable law.

(b) The Servicer may, at its option, transfer the servicing responsibilities with respect to any or all of the BANA Mortgage Loans to Wells Fargo Bank, N.A., as servicer; provided Wells Fargo Bank, N.A. agrees to service such Mortgage Loans pursuant to the terms of the Servicing Agreement, dated as of July 1, 2006, by and between Bank of America, National Association and Wells Fargo Bank, N.A., as modified by the Assignment, Assumption and Recognition Agreement, dated May 31, 2007, among Bank of America, National Association, Wells Fargo Bank, N.A., the Depositor, the Trustee and the Master Servicer and there exists no Event of Default thereunder. Section 4.05. Representations, Warranties and Covenants of the Servicer.

(iv) There is no action, suit, proceeding or investigation pending or, to the best knowledge of the Servicer, threatened against the Servicer which, either individually or in the aggregate, would result in any material adverse change in the business, operations, financial condition, properties or assets of the Servicer, or in any material impairment of the right or ability of the Servicer to carry on its business substantially as now conducted or which would draw into question the validity of this Agreement or the Mortgage Loans or of any action taken or to be taken in connection with the obligations of the Servicer contemplated herein, or which would materially impair the ability of the Servicer to perform under the terms of this Agreement. (b) The representations and warranties made pursuant to this Section 4.05 shall survive delivery of the Mortgage Files to the Trustee for the benefit of the Certificateholders. -27- Section 4.06.

If any one of the following events ("Events of Default") shall occur and be continuing: (a) any failure by the Servicer to deposit amounts in the BANA Custodial Account in the amount and manner provided herein so as to enable the Securities Administrator to distribute to Holders of Certificates any payment required to be made under the terms of such Certificates and this Agreement (other than the payments required to be made under Section 2.19); or (b) failure on the part of the Servicer duly to observe or perform in any material respect any other covenants or agreements of the 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 Servicer by the Master Servicer, the, Securities Administrator, the Trustee or -28- the Depositor, or to the Servicer, the Master Servicer, the Depositor, the Securities Administrator and the Trustee by the Holders of Certificates evidencing Voting Rights aggregating not less than 25% of all Certificates affected thereby; or (c) 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 Servicer, or for the winding up or liquidation of the Servicer's affairs, and the continuance of any such decree or order unstayed and in effect for a period of 60 consecutive days; or (d) the consent by the 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 Servicer or of or relating to substantially all of its property; or the 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; (e) the failure of the Servicer to remit any Monthly Advance required to be remitted by the Servicer pursuant to Section 2.19 which failure continues unremedied at 3:00 p.m. Eastern time on the Business Day prior to the related Distribution Date; (f) failure by the Servicer to duly perform, within the required time period, its obligations under Sections 2.17, 2.18 and 2.21, which failure continues unremedied for a period of ten (10) days after the date of such failure; then, and in each and every such case (other than clause (e) hereof), so long as an Event of Default shall not have been remedied by the Servicer, the Master Servicer shall, pursuant to the Pooling and Servicing Agreement, by notice then given in writing to the Servicer and the Depositor, terminate all of the rights and obligations of the Servicer under this Agreement. If an Event of Default described in clause (e) hereof shall occur, the Master Servicer shall, by notice to the Servicer and the Securities Administrator, terminate all of the rights and obligations of the Servicer under this Agreement and in and to the BANA Mortgage Loans and proceeds thereof and the Master Servicer or a successor Servicer appointed pursuant to Section 5.02 shall make the Advance which the Servicer failed to make. On or after the receipt by the Servicer of such written notice, all authority and power of the Servicer under this Agreement, whether with respect to the Certificates or the BANA Mortgage Loans or otherwise, shall pass to and be vested in the Master Servicer pursuant to and under this Section 5.01 and Section 5.02(a), unless and until such time as the Master Servicer shall appoint a successor Servicer pursuant to Section 5.02, and, without limitation, the Master Servicer is hereby authorized and empowered to execute and deliver, on behalf of the Servicer, as attorney-in-fact or otherwise, any and all documents and other instruments, and to do or accomplish all other acts or things necessary or appropriate to effect the purposes of such notice of termination, whether to complete the transfer and endorsement of the BANA Mortgage Loans and related documents, or otherwise, including, without limitation, the recordation of the assignments of the BANA Mortgage Loans to it.

All costs and expenses (including attorneys' fees) incurred in connection with transferring the Mortgage Files to the successor Servicer and amending this Agreement to reflect such succession as Servicer pursuant to this Section 5.01 shall be paid by the predecessor Servicer. Notwithstanding the termination of the Servicer pursuant hereto, the Servicer shall remain liable for any causes of action arising out of any Event of Default occurring prior to such termination. Section 5.02. Master Servicer to Act; Appointment of Successor. (a) Within 90 days of the time the Servicer receives a notice of termination pursuant to Section 5.01, the Master Servicer (or other named successor) shall be the successor in all respects to the 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 the Servicer by the terms and provisions hereof or shall appoint a successor pursuant to Section 2.06. Notwithstanding the foregoing, (i) the parties hereto agree that the Master Servicer, in its capacity as successor Servicer, immediately will assume all of the obligations of the Servicer under this Agreement, (ii) the Master Servicer, in its capacity as successor Servicer, shall not be responsible for the lack of information and/or documents that it cannot obtain through reasonable efforts and (iii) under no circumstances shall any provision of this Agreement be construed to require the Master Servicer, acting in its capacity as successor to the Servicer, 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 5.02(b), 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 $10,000,000 as the successor to the terminated Servicer hereunder in the assumption of all or any part of the responsibilities, duties or liabilities of the 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 a successor Servicer shall not affect any liability of the predecessor Servicer which may have arisen under this Agreement prior to its termination as Servicer, nor shall any successor Servicer be liable for any acts or omissions of the predecessor Servicer or for any breach by the 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 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. All Servicing Transfer Costs shall be paid by the predecessor Servicer upon presentation of reasonable documentation of such costs, and if such predecessor Servicer defaults in its obligation to pay such costs, such costs shall be paid by the Trust. -30- (b) In connection with the appointment of a successor Servicer or the assumption of the duties of the Servicer, as specified in Section 5.02(a), the Master Servicer may make such arrangements for the compensation of such successor as it and such successor agree. (c) Any successor, including the Master Servicer, to the Servicer as servicer shall during the term of its service as servicer maintain in force (i) a policy or policies of insurance covering errors and omissions in the performance of its obligations as servicer hereunder and (ii) a fidelity bond in respect of its officers, employees and agents to the same extent as the Servicer is so required pursuant to Section 2.03. ARTICLE VI TERMINATION Section 6.01. Termination upon Purchase or Liquidation of All Mortgage Loans. Subject to Section 10.02 of the Pooling and Servicing Agreement, the respective obligations and responsibilities of the Depositor and the Servicer created hereby shall terminate upon the earlier of (a) the last action required to be taken by the Securities Administrator on the Final Distribution Date pursuant to Article X of the Pooling and Servicing Agreement or (b) the final payment or other liquidation (or any advance with respect thereto) of the last BANA Mortgage Loan remaining in the Trust Estate or the disposition of all related REO Property.

Any such amendment shall be deemed not to adversely affect in any material respect any interest of the Certificateholders in the BANA Mortgage Loans if the Trustee and the Securities Administrator each receives written confirmation from each Rating Agency that such amendment will not cause such Rating Agency to reduce, qualify or withdraw the then current rating assigned to the Certificates (and any Opinion of Counsel received by the Trustee, Securities Administrator and the Master Servicer in connection with any such amendment may rely expressly on such confirmation as the basis therefore); provided, however, this Agreement may be amended by the Servicer and the Depositor from time to time without the delivery of an Opinion of Counsel described above to the extent necessary, in the judgment of the Servicer and its counsel, to comply with the rules and regulations of the SEC. -31- Section 7.02.
