WHEREAS, from time to time certain other mortgage loans conveyed by the Depositor to the Trustee under the Trust Agreement on the Closing Date and serviced by other servicers may subsequent to the Closing Date be transferred to the Servicer for servicing under this Agreement and Exhibit A hereto will be amended to include such mortgage loans which will then be “Mortgage Loans” under this Agreement.

WHEREAS, the Seller desires that the Servicer service the Mortgage Loans pursuant to this Agreement, and the Servicer has agreed to do so, subject to the right of the Seller and of the Master Servicer to terminate the rights and obligations of the Servicer hereunder at any time and to the other conditions set forth herein.

WHEREAS, the Seller and the Servicer agree that the provisions of the Flow Servicing Agreement shall not apply to the Mortgage Loans for so long as the Mortgage Loans remain subject to the provisions of the Trust Agreement;

WHEREAS, the Master Servicer shall be obligated under the Trust Agreement, among other things, to supervise the servicing of the Mortgage Loans on behalf of the Trustee, and shall have the right, under certain circumstances, to terminate the rights and obligations of the Servicer under this Servicing Agreement.

WHEREAS, the Seller and the Servicer acknowledge and agree that the Seller will assign all of its rights and delegate all of its obligations hereunder (excluding the Seller’s rights and obligations as owner of the servicing rights relating to the Mortgage Loans) to the Depositor and the Depositor will assign all of its rights (but not the obligations, except as set forth in the Trust Agreement) hereunder to the Trustee pursuant to the Trust Agreement, and that each reference herein (other than with respect to the Seller’s ownership of the servicing rights) to the Seller is intended, unless otherwise specified, to mean the Seller or the Trustee, as assignee, whichever is the owner of the Mortgage Loans from time to time.

ARTICLE III.

SERVICING OF THE MORTGAGE LOANS

Section 3.01

Servicer to Service.

The Servicer, as an independent contractor, shall service and administer the Mortgage Loans from and after the Closing Date or Servicing Transfer Date, as applicable, and shall have full power and authority, acting alone, to do any and all things in connection with such servicing and administration which the Servicer may deem necessary or desirable, consistent with the terms of this Agreement and with Accepted Servicing Practices.

The Seller, the Master Servicer and the Servicer additionally agree that the Servicer will fully furnish, in accordance with the Fair Credit Reporting Act of 1970, as amended (the “Fair Credit Reporting Act”) and its implementing regulations, accurate and complete information (e.g., favorable and unfavorable) on its borrower credit files to Equifax, Experian and Trans Union Credit Information Company (three of the credit repositories), on a monthly basis.

The Seller and the Servicer additionally agree as follows:

(a)

The Servicer shall (i) record or cause to be recorded the Mortgage or the Assignment of Mortgage, as applicable, with respect to all MERS Eligible Mortgage Loans, in the name of MERS, or shall ascertain that such have previously been so recorded; (ii) with the cooperation of the Trustee, take such actions as are necessary to cause the Trustee to be clearly identified as the owner of each MERS Mortgage Loan and each MERS Eligible Mortgage Loan on the records of MERS for purposes of the system of recording transfers of beneficial ownership of mortgages maintained by MERS; (iii) prepare or cause to be prepared all Assignments of Mortgage with respect to all Non-MERS Eligible Mortgage Loans; (iv) record or cause to be recorded, subject to Section 2.02(b) hereof, all Assignments of Mortgage with respect to Non-MERS Mortgage Loans in the name of the Trustee; (v) pay the recording costs pursuant to Section 2.02 hereof; and/or (vi) track such Mortgages and Assignments of Mortgage to ensure they have been recorded. The Servicer shall be entitled to be paid by the Seller fees for the preparation and recordation of the Mortgages and Assignments of Mortgage. After the expenses of such recording costs pursuant to Section 2.02 hereof shall have been paid by the Servicer, the Servicer shall submit to the Seller a reasonably detailed invoice for reimbursement of recording costs and fees it incurred hereunder.

(b)

If applicable, the Servicer shall, in accordance with the relevant provisions of the Xxxxxxxx-Xxxxxxxx National Affordable Housing Act of 1990, as the same may be amended from time to time, and the regulations provided in accordance with the Real Estate Settlement Procedures Act, provide notice to the Mortgagor of each Mortgage Loan of the transfer of the servicing thereto to the Servicer.

(c)

The Servicer shall be responsible for the preparation of and costs associated with notifications to Mortgagors of the assumption of servicing by the Servicer.

Consistent with the terms of this Agreement and except as provided in Section 3.19, the Servicer may waive any late payment charge, assumption fee or other fee that may be collected in the ordinary course of servicing the Mortgage Loans. The Servicer shall not make any future advances to any obligor under any Mortgage Loan, and (unless the Mortgagor is in default with respect to the Mortgage Loan or such default is, in the judgment of the Servicer, reasonably foreseeable) the Servicer shall not permit any modification of any material term of any Mortgage Loan, including any modification that would change the Mortgage Interest Rate, defer or forgive the payment of principal or interest, reduce or increase the outstanding principal balance (except for actual payments of principal) or change the final maturity date on such Mortgage Loan. In the event of any such modification which permits the deferral of interest or principal payments on any Mortgage Loan, the Servicer shall, on the Business Day immediately preceding the Remittance Date in any month in which any such principal or interest payment has been deferred, make a Monthly Advance in accordance with Section 4.03, in an amount equal to the difference between (i) such month’s principal and one month’s interest at the Mortgage Loan Remittance Rate on the unpaid principal balance of such Mortgage Loan and (ii) the amount paid by the Mortgagor. The Servicer shall be entitled to reimbursement for such advances to the same extent as for all other advances made pursuant to Section 4.03. Without limiting the generality of the foregoing, the Servicer shall continue, and is hereby authorized and empowered, to execute and deliver on behalf of itself and the Trustee, all instruments of satisfaction or cancellation, or of partial or full release, discharge and all other comparable instruments, with respect to the Mortgage Loans and with respect to the Mortgaged Properties. Upon the request of the Servicer, the Trustee shall execute and deliver to the Servicer any powers of attorney and other documents, furnished to it by the Servicer and reasonably satisfactory to the Trustee, necessary or appropriate to enable the Servicer to carry out its servicing and administrative duties under this Agreement. Notwithstanding anything contained herein to the contrary, the Servicer shall not, without the Trustee’s written consent: (i) initiate any action suit or proceeding solely under the Trustee’s name without indicating the Servicer’s representative capacity; or (ii) take any action with the intent to cause, and that actually causes, the Trustee to be registered to do business in any state. Promptly after the execution of any assumption, modification, consolidation or extension of any Mortgage Loan, the Servicer shall forward to the Master Servicer copies of any documents evidencing such assumption, modification, consolidation or extension. Notwithstanding anything to the contrary contained in this Servicing Agreement, the Servicer shall not make or permit any modification, waiver or amendment of any term of any Mortgage Loan that would cause any REMIC created under the Trust Agreement to fail to qualify as a REMIC or result in the imposition of any tax under Section 860F(a) or Section 860G(d) of the Code.

Notwithstanding anything to the contrary in this Agreement, the Servicer shall not (unless the Servicer determines, in its own discretion, that there exists a situation of extreme hardship to the Mortgagor), waive any premium or penalty in connection with a prepayment of principal of any Mortgage Loan, and shall not consent to the modification of any Mortgage Note to the extent that such modification relates to payment of a prepayment premium or penalty.

In servicing and administering the Mortgage Loans, the Servicer shall employ procedures (including collection procedures) and exercise the same care that it customarily employs and exercises in servicing and administering mortgage loans for its own account, giving due consideration to Accepted Servicing Practices where such practices do not conflict with the requirements of this Agreement, the Xxxxxx Xxx Guides, and the Master Servicer’s and Seller’s reliance on the Servicer.

Section 3.02

Collection of Mortgage Loan Payments.

Continuously from the Closing Date or Servicing Transfer Date, as applicable, until the date each Mortgage Loan ceases to be subject to this Agreement, the Servicer shall proceed diligently to collect all payments due under each of the Mortgage Loans when the same shall become due and payable and shall take special care in ascertaining and estimating Escrow Payments and all other charges that will become due and payable with respect to the Mortgage Loans and each related Mortgaged Property, 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.

Section 3.03

Establishment of and Deposits to Custodial Account.

The Servicer shall segregate and hold all funds collected and received pursuant to the Mortgage Loans separate and apart from any of its own funds and general assets and shall establish and maintain one or more Custodial Accounts, in the form of time deposit or demand accounts, titled as directed by the Master Servicer. The Custodial Account shall be an Eligible Deposit Account established with an Eligible Institution. Any funds deposited in the Custodial Account may be invested in Eligible Investments subject to the provisions of Section 3.11 hereof. Funds deposited in the Custodial Account may be drawn on by the Servicer in accordance with Section 3.04. The creation of any Custodial Account shall be evidenced by a certification in the form of Exhibit B. A copy of such certification shall be furnished to the Master Servicer and, upon request, to any subsequent owner of the Mortgage Loans.

The Servicer shall deposit in the Custodial Account on a daily basis, and retain therein, the following collections received by the Servicer and payments made by the Servicer after the Closing Date or Servicing Transfer Date, as applicable:

(i)

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

(ii)

all payments on account of interest on the Mortgage Loans adjusted to the Mortgage Loan Remittance Rate;

(iii)

all Liquidation Proceeds;

all Insurance Proceeds (other than amounts applied to the restoration or repair of the Mortgaged Property or immediately released to the Mortgagor in accordance with Accepted Servicing Practices);

(v)

all Condemnation Proceeds that are not applied to the restoration or repair of the Mortgaged Property or released to the Mortgagor;

(vi)

with respect to each Principal Prepayment in full or in part, the Prepayment Interest Shortfall Amount, if any, for the month of distribution. Such deposit shall be made from the Servicer’s own funds, without reimbursement therefor, up to a maximum amount per month of the Servicing Fee actually received for such month for the Mortgage Loans;

(vii)

all Monthly Advances made by the Servicer pursuant to Section 4.03;

(viii)

any amounts required to be deposited by the Servicer in connection with the deductible clause in any blanket hazard insurance policy;

any amounts received with respect to or related to any REO Property or REO Disposition Proceeds;

(x)

any Prepayment Penalty Amounts; and

(xi)

any other amount required hereunder to be deposited by the Servicer in the Custodial Account.

The foregoing requirements for deposit into the Custodial Account shall be exclusive, it being understood and agreed that, without limiting the generality of the foregoing, payments in the nature of the Servicing Fee and Ancillary Income need not be deposited by the Servicer into the Custodial Account.

Any interest paid on funds deposited in the Custodial Account by the depository institution shall accrue to the benefit of the Servicer and the Servicer shall be entitled to retain and withdraw such interest from the Custodial Account pursuant to Section 3.04. Additionally, any other benefit derived from the Custodial Account associated with the receipt, disbursement and accumulation of principal, interest, taxes, hazard insurance, mortgage insurance, etc. shall accrue to the Servicer.

Section 3.04

Permitted Withdrawals From Custodial Account.

The Servicer shall, from time to time, withdraw funds from the Custodial Account for the following purposes:

(i)

to make payments to the Master Servicer in the amounts and in the manner provided for in Section 4.01;

(ii)

with respect to each LPMI Loan, in the amount of the related LPMI Fee, to make payments with respect to premiums for LPMI Policies in accordance with Section 3.07;

(iii)

in the event the Servicer has elected not to retain the Servicing Fee out of any Mortgagor payments on account of interest or other recovery of interest with respect to a particular Mortgage Loan (including late collections of interest on such Mortgage Loan, or interest portions of Insurance Proceeds, Condemnation Proceeds or Liquidation Proceeds) prior to the deposit of such Mortgagor payment or recovery in the Custodial Account, to pay to itself the related Servicing Fee from all such Mortgagor payments on account of interest or other such recovery for interest with respect to that Mortgage Loan;

(iv)

to pay itself investment earnings on funds deposited in the Custodial Account;

(v)

to clear and terminate the Custodial Account upon the termination of this Agreement;

(vi)

to transfer funds to another Eligible Institution in accordance with Section 3.11 hereof;

(vii)

to invest funds in certain Eligible Investments in accordance with Section 3.11 hereof;

(viii)

to reimburse itself to the extent of funds in the Custodial Account for Monthly Advances of the Servicer’s funds made pursuant to Section 4.03, the Servicer's right to reimburse itself pursuant to this subclause (viii) with respect to any Mortgage Loan being limited to amounts received on or in respect of the related Mortgage Loan which represent late recoveries of payments of principal or interest with respect to which a Monthly Advance was made, it being understood that, in the case of any such reimbursement, the Servicer’s right thereto shall be prior to the rights of the Trust Fund, provided, however, that following the final liquidation of a Mortgage Loan, the Servicer may reimburse itself for previously unreimbursed Monthly Advances in excess of Liquidation Proceeds or Insurance Proceeds with respect to such Mortgage Loan from any funds in the Custodial Account, it being understood, in the case of any such reimbursement, that the Servicer’s right thereto shall be prior to the rights of the Trust Fund. The Servicer may recover at any time from amounts on deposit in the Custodial Account the amount of any Monthly Advances that the Servicer deems nonrecoverable or that remain unreimbursed to the Servicer from related Liquidation Proceeds after the final liquidation of the Mortgage Loan;

(ix)

to reimburse itself for remaining unreimbursed Servicing Advances with respect to any defaulted Mortgage Loan as to which the Servicer has determined that all amounts that it expects to recover on behalf of the Trust Fund from or on account of such Mortgage Loan have been recovered;

(x)

to reimburse itself for expenses incurred or reimbursable to the Servicer pursuant to Sections 3.12 and 6.03 to the extent not previously reimbursed under clause (viii) of this Section 3.04; and

(xi)

to withdraw funds deposited in error.

Section 3.05

Establishment of and Deposits to Escrow Account.

The Servicer shall segregate and hold all funds collected and received pursuant to a Mortgage Loan constituting Escrow Payments separate and apart from any of its own funds and general assets and shall establish and maintain one or more Escrow Accounts, in the form of time deposit or demand accounts, titled as directed by the Master Servicer. Each Escrow Account shall be an Eligible Deposit Account established with an Eligible Institution in a manner that shall provide maximum available insurance thereunder. Funds deposited in the Escrow Account may be drawn on by the Servicer in accordance with Section 3.06. The creation of any Escrow Account shall be evidenced by a certification in the form of Exhibit C. A copy of such certification shall be furnished to the Master Servicer and, upon request, to any subsequent owner of the Mortgage Loans.

The Servicer shall deposit in the Escrow Account or Accounts on a daily basis, and retain therein:

(i)

all Escrow Payments collected on account of the Mortgage Loans, for the purpose of effecting timely payment of any such items as required under the terms of this Agreement; and

(ii)

all amounts representing Insurance Proceeds or Condemnation Proceeds that are to be applied to the restoration or repair of any Mortgaged Property.

The Servicer shall make withdrawals from the Escrow Account only to effect such payments as are required under this Agreement, as set forth in Section 3.06. The Servicer shall retain any interest paid on funds deposited in the Escrow Account by the depository institution, other than interest on escrowed funds required by law to be paid to the Mortgagor. Additionally, any other benefit derived from the Escrow Account associated with the receipt, disbursement and accumulation of principal, interest, taxes, hazard insurance, mortgage insurance, etc. shall accrue to the Servicer. To the extent required by law, the Servicer shall pay interest on escrowed funds to the Mortgagor notwithstanding that the Escrow Account may be non-interest bearing or that interest paid thereon is insufficient for such purposes.

Section 3.06

Permitted Withdrawals From Escrow Account.

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

(i)

to effect timely payments of ground rents, taxes, assessments, water rates, sewer rents, mortgage insurance premiums, condominium charges, fire and hazard insurance premiums or other items constituting Escrow Payments for the related Mortgage;

(ii)

to refund to any Mortgagor any funds found to be in excess of the amounts required under the terms of the related Mortgage Loan;

(iii)

for transfer to the Custodial Account and application to reduce the principal balance of the Mortgage Loan in accordance with the terms of the related Mortgage and Mortgage Note;

(iv)

to reimburse the Servicer for any Servicing Advance made by the Servicer with respect to a related Mortgage Loan, but only from amounts received on the related Mortgage Loan which represent late collections of Escrow Payments;

(v)

for application to restoration or repair of the Mortgaged Property in accordance with the Xxxxxx Mae Guides;

(vi)

to pay to the Servicer, or any Mortgagor to the extent required by law, any interest paid on the funds deposited in the Escrow Account;

(vii)

to remove funds inadvertently placed in the Escrow Account by the Servicer; and

(viii)

to clear and terminate the Escrow Account on the termination of this Agreement.

Section 3.07

Maintenance of PMI Policy and/or LPMI Policy; Claims.

The Servicer shall comply with all provisions of applicable state and federal law relating to the cancellation of, or collection of premiums with respect to, PMI 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.

With respect to each Mortgage Loan (other than LPMI Loans) with a loan to value ratio at origination in excess of 80%, the Servicer shall maintain or cause the Mortgagor to maintain (to the extent that the Mortgage Loan requires the Mortgagor to maintain such insurance) in full force and effect a PMI Policy, and shall pay or shall cause the Mortgagor to pay the premium thereon on a timely basis, until the LTV of such Mortgage Loan is reduced to 80%. In the event that such PMI Policy shall be terminated, the Servicer shall obtain from another Qualified Insurer a comparable replacement policy, with a total coverage equal to the remaining coverage of such terminated PMI Policy, at substantially the same fee level. The Servicer shall not take any action which would result in noncoverage under any applicable PMI Policy of any loss which, but for the actions of the Servicer would have been covered thereunder. In connection with any assumption or substitution agreements entered into or to be entered into with respect to a Mortgage Loan, the Servicer shall promptly notify the insurer under the related PMI Policy, if any, of such assumption or substitution of liability in accordance with the terms of such PMI Policy and shall take all actions which may be required by such insurer as a condition to the continuation of coverage under such PMI Policy. If such PMI Policy is terminated as a result of such assumption or substitution of liability, the Servicer shall obtain a replacement PMI Policy as provided above.

The Servicer shall take all such actions as are necessary to service, maintain and administer the LPMI Loans in accordance with the LPMI Policy and to perform and enforce the rights of the insured under such LPMI Policy. Except as expressly set forth herein, the Servicer shall have full authority on behalf of the Trust Fund to do anything it reasonably deems appropriate or desirable in connection with the servicing, maintenance and administration of the LPMI Policy. The Servicer shall not modify or assume a Mortgage Loan covered by the LPMI Policy or take any other action with respect to such Mortgage Loan which would result in non-coverage under the LPMI Policy of any loss which, but for the actions of the Servicer, would have been covered thereunder. If the LPMI Insurer fails to pay a claim under the LPMI Policy as a result of breach by the Servicer of its obligations hereunder or under the LPMI Policy, the Servicer shall be required to deposit in the Custodial Account on or prior to the next succeeding Remittance Date an amount equal to such unpaid claim from its own funds without any right to reimbursement from the Trust Fund. The Servicer shall cooperate with the LPMI Insurer and the Master Servicer and shall use its best efforts to furnish all reasonable aid, evidence and information in the possession of the Servicer to which the Servicer has access with respect to any LPMI Loan; provided, however, notwithstanding anything to the contrary contained in any LPMI Policy, the Servicer shall not be required to submit any reports to the LPMI Insurer until a reporting date that is at least 15 days after the Servicer has received sufficient loan level information from the Seller, the Master Servicer or the LPMI Insurer to appropriately code its servicing system in accordance with the LPMI Insurer’s requirements.

In connection with its activities as servicer, the Servicer agrees to prepare and present, on behalf of itself and the Trustee, claims to the insurer under any PMI Policy or LPMI Policy in a timely fashion in accordance with the terms of such PMI Policy or LPMI Policy and, in this regard, to take such action as shall be necessary to permit recovery under any PMI Policy or LPMI Policy respecting a defaulted Mortgage Loan. Any amounts collected by the Servicer under any PMI Policy or LPMI Policy shall be deposited in the Custodial Account, subject to withdrawal pursuant to Section 3.04.

Section 3.08

Fidelity Bond and Errors and Omissions Insurance.

The Servicer shall keep in force during the term of this Agreement a Fidelity Bond and Errors and Omissions Insurance Policy. Such Fidelity Bond and Errors and Omissions Insurance shall be maintained with recognized insurers and shall be in such form and amount as would permit the Servicer to be qualified as a Xxxxxx Xxx or Xxxxxxx Mac seller-servicer. The Servicer shall be deemed to have complied with this provision if an affiliate of the Servicer has such errors and omissions and fidelity bond coverage and, by the terms of such insurance policy or fidelity bond, the coverage afforded thereunder extends to the Servicer. The Servicer shall furnish to the Master Servicer or Trustee a copy of each such bond and insurance policy if (i) the Master Servicer or Trustee so requests and (ii) the Servicer is not an affiliate of Xxxxxx Brothers Inc. at the time of such request.

Section 3.09

Notification of Adjustments.

With respect to each Adjustable Rate Mortgage Loan, the Servicer shall adjust the Mortgage Interest Rate on the related interest rate adjustment date and shall adjust the Monthly Payment on the related mortgage payment adjustment date, if applicable, in compliance with the requirements of applicable law and the related Mortgage and Mortgage Note. The Servicer shall execute and deliver any and all necessary notices required under applicable law and the terms of the related Mortgage Note and Mortgage regarding the Mortgage Interest Rate and Monthly Payment adjustments. The Servicer shall promptly, upon written request therefor, deliver to the Master Servicer such notifications and any additional applicable data regarding such adjustments and the methods used to calculate and implement such adjustments. Upon the discovery by the Servicer or the receipt of notice from the Master Servicer that the Servicer has failed to adjust a Mortgage Interest Rate or Monthly Payment in accordance with the terms of the related Mortgage Note, the Servicer shall immediately deposit in the Custodial Account from its own funds the amount of any interest loss or deferral caused thereby.

Section 3.10

Completion and Recordation of Assignments of Mortgage.

As soon as practicable after the Closing Date, the Servicing Transfer Date or the date on which a Qualifying Substitute Mortgage Loan is delivered pursuant to Section 2.05 of the Trust Agreement, as applicable (but in no event more than 90 days thereafter except to the extent delays are caused by the applicable public recording office), the Servicer shall cause the endorsements on the Mortgage Note (if applicable), and the Assignments of Mortgage (subject to Section 3.01(a)) to be completed in the name of the Trustee (or MERS, as applicable).

Section 3.11

Protection of Accounts.

The Servicer may transfer the Custodial Account or any Escrow Account to a different Eligible Institution from time to time; provided that in the event the Custodial Account or any Escrow Account is held in a depository institution or trust company that ceases to be an Eligible Institution, the Servicer shall transfer such Custodial Account or Escrow Account, as the case may be, to an Eligible Institution. Such transfer shall be made only upon obtaining the consent of the Master Servicer, which consent shall not be withheld unreasonably.

The Servicer shall bear any expenses, losses or damages sustained by the Master Servicer or the Trustee if the Custodial Account and/or the Escrow Account are not demand deposit accounts.

Amounts on deposit in the Custodial Account and the Escrow Account may at the option of the Servicer be invested in Eligible Investments. Any such Eligible Investment shall mature no later than the Business Day immediately preceding the related Remittance Date; provided, however, that if such Eligible Investment is an obligation of a Qualified Depository (other than the Servicer) that maintains the Custodial Account or the Escrow Account, then such Eligible Investment may mature on the related Remittance Date. Any such Eligible Investment shall be made in the name of the Servicer in trust for the benefit of the Trustee. All income on or gain realized from any such Eligible Investment shall be for the benefit of the Servicer and may be withdrawn at any time by the Servicer. Any losses incurred in respect of any such investment shall be deposited in the Custodial Account or the Escrow Account, by the Servicer out of its own funds immediately as realized.

Section 3.12

Payment of Taxes, Insurance and Other Charges.

With respect to each Mortgage Loan, the Servicer shall maintain accurate records reflecting the status of ground rents, taxes, assessments, water rates, sewer rents, and other charges which are or may become a lien upon the Mortgaged Property and the status of PMI Policy and LPMI Policy (if any) premiums and fire and hazard insurance coverage and shall obtain, from time to time, all bills for the payment of such charges (including renewal premiums) and shall effect payment thereof prior to the applicable penalty or termination date, employing for such purpose deposits of the Mortgagor in the Escrow Account which shall have been estimated and accumulated by the Servicer in amounts sufficient for such purposes, as allowed under the terms of the Mortgage. The Servicer shall not be required to maintain records with respect to the payment of LPMI Premiums unless the Servicer shall be required to make payment of such premiums and such requirement shall be indicated on the Mortgage Loan Schedule with respect to each applicable Mortgage Loan. The Servicer assumes full responsibility for the timely payment of all such bills, shall effect timely payment of all such charges irrespective of each Mortgagor’s faithful performance in the payment of same or the making of the Escrow Payments, and shall make advances from its own funds to effect such payments. With regard to any Mortgage Loans for which the Mortgagor is not required to escrow Escrow Payments with the Servicer, the Servicer shall use reasonable efforts consistent with Accepted Servicing Practices to determine that any such payments are made by the Mortgagor at the time they first became due and shall insure that the Mortgaged Property is not lost to a tax lien as a result of nonpayment and that such Mortgage is not left uninsured and shall make advances from its own funds to effect any such delinquent payments to avoid the lapse of insurance coverage on the Mortgaged Property or to avoid the imposition of a tax lien.

Section 3.13

Maintenance of Hazard Insurance.

The Servicer shall cause to be maintained for each Mortgage Loan hazard insurance such that all buildings upon the Mortgaged Property are insured by a generally acceptable insurer against loss by fire, hazards of extended coverage and such other hazards as are customary in the area where the Mortgaged Property is located, in an amount which is at least equal to the greater of (i) the outstanding principal balance of the Mortgage Loan and (ii) an amount such that the proceeds thereof shall be sufficient to prevent the Mortgagor or the loss payee from becoming a co-insurer.

If upon origination of the Mortgage Loan, the related Mortgaged Property was located in an area identified in the Federal Register by the Flood Emergency Management Agency as having special flood hazards (and such flood insurance has been made available) a flood insurance policy meeting the requirements of the current guidelines of the Federal Insurance Administration is in effect with a generally acceptable insurance carrier in an amount representing coverage equal to the lesser of (i) the minimum amount required, under the terms of coverage, to compensate for any damage or loss on a replacement cost basis (or the unpaid balance of the mortgage if replacement cost coverage is not available for the type of building insured) and (ii) the maximum amount of insurance which is available under the Flood Disaster Protection Act of 1973, as amended. If at any time during the term of the Mortgage Loan, the Servicer determines in accordance with applicable law and pursuant to the Xxxxxx Xxx Guides that a Mortgaged Property is located in a special flood hazard area and is not covered by flood insurance or is covered in an amount less than the amount required by the Flood Disaster Protection Act of 1973, as amended, the Servicer shall notify the related Mortgagor that the Mortgagor must obtain such flood insurance coverage, and if said Mortgagor fails to obtain the required flood insurance coverage within forty-five (45) days after such notification, the Servicer shall force place the required flood insurance on the Mortgagor’s behalf.

Section 3.14

Maintenance of Mortgage Blanket Insurance.

The Servicer shall obtain and maintain a blanket policy insuring against losses arising from fire and hazards covered under extended coverage on all of the Mortgage Loans. To the extent such policy provides coverage in an amount equal to the amount required pursuant to Section 3.12 and otherwise complies with all other requirements of Section 3.12, it shall conclusively be deemed to have satisfied its obligations as set forth in Section 3.12. Any amounts collected by the Servicer under any such policy relating to a Mortgage Loan shall be deposited in the Custodial Account or Escrow Account subject to withdrawal pursuant to Sections 3.04 or 3.06. Such policy may contain a deductible clause, in which case, in the event that there shall not have been maintained on the related Mortgaged Property a policy complying with Section 3.12, and there shall have been a loss which would have been covered by such policy, the Servicer shall deposit in the Custodial Account at the time of such loss the amount not otherwise payable under the blanket policy because of such deductible clause, such amount to be deposited from the Servicer’s funds, without reimbursement therefor.

Section 3.15

Restoration of Mortgaged Property.

The Servicer need not obtain the approval of the Trustee or the Master Servicer prior to releasing any Insurance Proceeds or Condemnation Proceeds to the Mortgagor to be applied to the restoration or repair of the Mortgaged Property if such release is in accordance with Accepted Servicing Practices. At a minimum, with respect to claims greater than $10,000, the Servicer shall comply with the following conditions in connection with any such release of Insurance Proceeds or Condemnation Proceeds:

(i)

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

(ii)

the Servicer shall take all steps necessary to preserve the priority of the lien of the Mortgage, including, but not limited to requiring waivers with respect to mechanics’ and materialmen’s liens; and

(iii)

pending repairs or restoration, the Servicer shall place the Insurance Proceeds or Condemnation Proceeds in the Escrow Account.

Section 3.16

Title, Management and Disposition of REO Property.

In the event that title to any Mortgaged Property is acquired in foreclosure or by deed in lieu of foreclosure, the deed or certificate of sale shall be taken in the name of the Trustee or its nominee (or MERS, as applicable), or in the event the Trustee is not authorized or permitted to hold title to real property in the state where the REO Property is located, or would be adversely affected under the “doing business” or tax laws of such state by so holding title, the deed or certificate of sale shall be taken in the name of such Person or Persons as shall be consistent with an Opinion of Counsel obtained by the Servicer (with a copy delivered to the Trustee) from any attorney duly licensed to practice law in the state where the REO Property is located. The Person or Persons holding such title other than the Trustee shall acknowledge in writing that such title is being held as nominee for the Trustee.

The Servicer shall manage, conserve, protect and operate each REO Property for the Trustee solely for the purpose of its prompt disposition and sale. The Servicer, either itself or through an agent selected by the Servicer, shall manage, conserve, protect and operate the REO Property in the same manner that it manages, conserves, protects and operates other foreclosed property for its own account, and in the same manner that similar property in the same locality as the REO Property is managed. The Servicer shall attempt to sell the same (and may temporarily rent the same for a period not greater than one year, except as otherwise provided below) on such terms and conditions as the Servicer deems to be in the best interest of the Trustee and the Trust Fund.

The Servicer may permit an obligor to pay off a non-performing Mortgage Loan at less than its unpaid principal balance or chargeoff all or a portion of such non-performing Mortgage Loan if such discounted payoff or chargeoff is in accordance with Accepted Servicing Practices and the Servicer believes that such discounted payoff or chargeoff is in the best interest of the Trust Fund; provided that in the case of any proposed discounted payoff or proposed chargeoff, the Servicer shall notify the Master Servicer, by telecopy and telephone, of the proposed discounted payoff or chargeoff of any Mortgage Loan. The Master Servicer shall be deemed to have approved the discounted payoff or chargeoff of any Mortgage Loan unless the Master Servicer notifies the Servicer in writing, within five (5) Business Days after its receipt of the related notice, that it disapproves of the discounted payoff or chargeoff, in which case the Servicer shall not proceed with such discounted payoff or chargeoff.

Notwithstanding anything to the contrary contained in this Section 3.16, in connection with a foreclosure or acceptance of a deed in lieu of foreclosure, in the event the Servicer has reasonable cause to believe that a Mortgaged Property is contaminated by hazardous or toxic substances or wastes, or if the Trustee or the Master Servicer otherwise requests, an environmental inspection or review of such Mortgaged Property to be conducted by a qualified inspector shall be arranged by the Servicer. Upon completion of the inspection, the Servicer shall provide the Trustee and the Master Servicer with a written report of such environmental inspection. In the event that the environmental inspection report indicates that the Mortgaged Property is contaminated by hazardous or toxic substances or wastes, the Servicer shall not proceed with foreclosure or acceptance of a deed in lieu of foreclosure. In the event that the environmental inspection report is inconclusive as to whether or not the Mortgaged Property is contaminated by hazardous or toxic substances or wastes, the Servicer shall not, without the prior approval of the Master Servicer, proceed with foreclosure or acceptance of a deed in lieu of foreclosure. In such instance, the Master Servicer shall be deemed to have approved such foreclosure or acceptance of a deed in lieu of foreclosure unless the Master Servicer notifies the Servicer in writing, within two (2) Business Days after its receipt of written notice of the proposed foreclosure or deed in lieu of foreclosure from the Servicer, that it disapproves of the related foreclosure or acceptance of a deed in lieu of foreclosure. The Servicer shall be reimbursed for all Servicing Advances made pursuant to this paragraph with respect to the related Mortgaged Property from the Custodial Account.

Subject to the approval of the Master Servicer as described in this paragraph, the disposition of REO Property shall be carried out by the Servicer at such price, and upon such terms and conditions, as the Servicer deems to be in the best interests of the Trust Fund. Prior to acceptance by the Servicer of an offer to sell any REO Property, the Servicer shall notify the Master Servicer of such offer in writing which notification shall set forth all material terms of said offer (each, a “Notice of Sale”). The Master Servicer shall be deemed to have approved the sale of any REO Property unless the Master Servicer notifies the Servicer in writing, within two (2) Business Days after its receipt of the related Notice of Sale, that it disapproves of the related sale, in which case the Servicer shall not proceed with the sale. With respect to any REO Property, upon a REO Disposition, the Servicer shall be entitled to retain from REO Disposition Proceeds a disposition fee equal to $1,500.

In the event that the Trust Fund acquires any REO Property in connection with a default or imminent default on a Mortgage Loan, the Servicer shall dispose of such REO Property not later than the end of the third taxable year after the year of its acquisition by the Trust Fund unless the Servicer has applied for and received a grant of extension from the Internal Revenue Service to the effect that, under the REMIC Provisions and any relevant proposed legislation and under applicable state law, the applicable Trust REMIC may hold REO Property for a longer period without adversely affecting the REMIC status of such REMIC or causing the imposition of a federal or state tax upon such REMIC. If the Servicer has received such an extension, then the Servicer shall continue to attempt to sell the REO Property for its fair market value for such period longer than three years as such extension permits (the “Extended Period”). If the Servicer has not received such an extension and the Servicer is unable to sell the REO Property within the period ending 3 months before the end of such third taxable year after its acquisition by the Trust Fund or if the Servicer has received such an extension, and the Servicer is unable to sell the REO Property within the period ending three months before the close of the Extended Period, the Servicer shall, before the end of the three-year period or the Extended Period, as applicable, (i) purchase such REO Property at a price equal to the REO Property’s fair market value or (ii) auction the REO Property to the highest bidder (which may be the Servicer) in an auction reasonably designed to produce a fair price prior to the expiration of the three-year period or the Extended Period, as the case may be. The Trustee shall sign any document or take any other action reasonably requested by the Servicer which would enable the Servicer, on behalf of the Trust Fund, to request such grant of extension.

Notwithstanding any other provisions of this Agreement, no REO Property acquired by the Trust Fund shall be rented (or allowed to continue to be rented) or otherwise used by or on behalf of the Trust Fund in such a manner or pursuant to any terms that would: (i) cause such REO Property to fail to qualify as “foreclosure property” within the meaning of Section 860G(a)(8) of the Code; or (ii) subject any Trust REMIC to the imposition of any federal income taxes on the income earned from such REO Property, including any taxes imposed by reason of Sections 860F or 860G(c) of the Code, unless the Servicer has agreed to indemnify and hold harmless the Trust Fund with respect to the imposition of any such taxes.

The Servicer shall also maintain on each REO Property fire and hazard insurance with extended coverage in 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 and available under the Flood Disaster Protection Act of 1973, as amended, flood insurance in the amount required above.

The Servicer shall withdraw from the Custodial Account funds necessary for the proper operation, management and maintenance of the REO Property, including the cost of maintaining any hazard insurance pursuant to the Xxxxxx Xxx Guides. The Servicer shall make monthly distributions on each Remittance Date to the Master Servicer of the net cash flow from the REO Property (which shall equal the revenues from such REO Property net of the expenses described in this Section 3.16 and of any reserves reasonably required from time to time to be maintained to satisfy anticipated liabilities for such expenses).

If the Servicer determines that, in accordance with Accepted Servicing Practices, it is in the best interest of the Trustee or the Trust Fund not to proceed with foreclosure or accept a deed in lieu of foreclosure, the Servicer shall have the right to do so with the consent of the Master Servicer, whereupon the related Mortgage Loan shall be deemed to be finally liquidated and the Servicer shall have the right to release the lien of the Mortgage on the related Mortgaged Property and the Servicer shall be entitled to reimbursement for all outstanding unreimbursed Monthly Advances and Servicing Advances from the Custodial Account in accordance with Sections 3.04(viii) and (ix).

Section 3.17

Real Estate Owned Reports.

Together with the statement furnished pursuant to Section 4.02, the Servicer shall furnish to the Master Servicer on or before the Remittance Date each month a statement with respect to any REO Property covering the operation of such REO Property for the previous month and the Servicer’s efforts in connection with the sale of such REO Property and any rental of such REO Property incidental to the sale thereof for the previous month. That statement shall be accompanied by such other information as the Master Servicer shall reasonably request.

Section 3.18

MERS.

(a)

The Servicer shall use its Best Efforts to cause the Trustee to be identified as the owner of each MERS Mortgage Loan on the records of MERS for purposes of the system of recording transfers of beneficial ownership of mortgages maintained by MERS.

(b)

The Servicer shall maintain in good standing its membership in MERS. In addition, the Servicer shall comply with all rules, policies and procedures of MERS, including the Rules of Membership, as amended, and the MERS Procedures Manual, as amended.

(c)

With respect to all MERS Mortgage Loans serviced hereunder, the Servicer shall promptly notify MERS as to any transfer of beneficial ownership of such Mortgage Loans of which the Servicer has notice.

(d)

With respect to all MERS Mortgage Loans serviced hereunder, the Servicer shall notify MERS as to any transfer of servicing pursuant to Section 3.15 or Section 9.01 within 10 Business Days of such transfer of servicing. The Servicer shall cooperate with the Trustee, the Master Servicer and any successor servicer to the extent necessary to ensure that such transfer of servicing is appropriately reflected on the MERS system.

Section 3.19

Waiver of Prepayment Penalty Amounts.

Except as provided below, the Servicer or any designee of the Servicer shall not waive any Prepayment Penalty Amount with respect to any Mortgage Loan. If the Servicer or its designee fails to collect a Prepayment Penalty Amount at the time of the related prepayment of any Mortgage Loan subject to such Prepayment Penalty Amount, the Servicer shall pay to the Trust Fund at such time (by deposit to the Custodial Account) an amount equal to the amount of the Prepayment Penalty Amount not collected; provided, however, the Servicer shall not have any obligation to pay the amount of any uncollected Prepayment Penalty Amount under this Section 3.19 if the failure to collect such amount is the result of inaccurate or incomplete information in the Prepayment Penalty Amount Schedule provided by the Seller and which is included as part of the Mortgage Loan Schedule attached hereto as Exhibit A. The Prepayment Penalty Amounts listed on the Prepayment Penalty Amount Schedule attached hereto as Exhibit A are complete, true and accurate and may be relied on by the Servicer in its calculation of Prepayment Penalty Amounts. If the Prepayment Penalty Amount data set forth on Exhibit A is incorrect, then the Servicer shall have no liability for any loss resulting from calculation of Prepayment Penalty Amounts using the data provided. Notwithstanding the above, the Servicer or its designee may waive a Prepayment Penalty Amount without paying to the Trust Fund the amount of such Prepayment Penalty Amount only if such Prepayment Penalty Amount (i) relates to a defaulted Mortgage Loan or a reasonably foreseeable default, such waiver is standard and customary in servicing similar mortgage loans to the Mortgage Loan, and such waiver, in the reasonable judgment of the Servicer would maximize recovery of total proceeds from the Mortgage Loan, taking into account the amount of such Prepayment Charge and the related Mortgage Loan, or (ii) relates to a prepayment charge the collection of which, if collected, would be a violation of applicable laws.

Section 3.20

Safeguarding Customer Information.

The Servicer has implemented and will maintain security measures designed to meet the objectives of the Interagency Guidelines Establishing Standards for Safeguarding Customer Information published in final form on February 1, 2001, 66 Fed. Reg. 8616 and the rules promulgated thereunder, as amended from time to time (the “Guidelines”).

The Servicer shall promptly provide the Master Servicer and the Trustee information reasonably available to it regarding such security measures upon the reasonable request of the Master Servicer and the Trustee which information shall include, but not be limited to, any Statement on Auditing Standards (SAS) No. 70 report covering the Servicer’s operations, and any other audit reports, summaries of test results or equivalent measures taken by the Servicer with respect to its security measures to the extent reasonably necessary in order for the Seller to satisfy its obligations under the Guidelines.

With respect to any remittance received by the Master Servicer after the Business Day on which such payment was due, the Servicer shall pay to the Master Servicer interest on any 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 Custodial Account by the Servicer on the date such late payment is made and shall cover the period commencing with the day following such Business Day and ending with the Business Day on which such payment is made, both inclusive. Such interest shall be remitted along with the distribution payable on the next succeeding Remittance Date. The payment by the 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 Servicer.

In addition, no later than March 15 of each calendar year, commencing March 15, 2005, the Servicer shall furnish to each Person who was an owner of the Mortgage Loans at any time during such calendar year as required by applicable law or if not required by applicable law, at the request of such owner as to the aggregate of remittances for the applicable portion of such year.

The Master Servicer may request that the Servicer provide, at the Master Servicer’s expense, an appraisal or a broker price opinion on any Mortgage Loan which is 90 days or more delinquent. The Servicer shall use its best efforts to deliver such appraisal or broker price opinion to the Master Servicer within 15 calendar days after such request.

Such obligation of the Servicer shall be deemed to have been satisfied to the extent that substantially comparable information shall be provided by the Servicer pursuant to any requirements of the Internal Revenue Code as from time to time are in force.

Beginning with calendar year 2004, the Servicer shall provide the Master Servicer with such information concerning the Mortgage Loans as is necessary for the Master Servicer or the Trustee to prepare the Trust Fund’s federal income tax return as the Master Servicer or the Trustee may reasonably request from time to time.

The Servicer’s obligation to make such Monthly Advances as to any Mortgage Loan will continue through the last Monthly Payment due prior to the payment in full of the Mortgage Loan, or through the last Remittance Date prior to the Remittance Date for the distribution of all Liquidation Proceeds and other payments or recoveries (including Insurance Proceeds and Condemnation Proceeds) with respect to the Mortgage Loan unless the Servicer deems such Monthly Advances to be unrecoverable, as evidenced by an Officer’s Certificate of the Servicer delivered to the Master Servicer.

GENERAL SERVICING PROCEDURES

Section 5.01

Servicing Compensation.

As consideration for servicing the Mortgage Loans subject to this Agreement, the Servicer shall retain (i) the relevant Servicing Fee for each Mortgage Loan remaining subject to this Agreement during any month and (ii) Ancillary Income. In addition, if at any time the Servicer is the Retained Interest Holder with respect to any Mortgage Loans, then the Servicer, as the Retained Interest Holder, shall retain an amount equal to the Retained Interest relating to such Mortgage Loans; provided, that (i) the Trustee and the Master Servicer shall have no obligation to make payment of the Retained Interest to the Servicer and (ii) the Servicer’s right to retain the Retained Interest is limited to (and the Retained Interest may only be retained from) the interest portion (including recoveries with respect to interest from Liquidation Proceeds to the extent permitted by Section 3.04 of this Agreement) of the Monthly Payments collected by the Servicer with respect to those Mortgage Loans for which payment is in fact made of the entire amount of the Monthly Payment. The Servicing Fee shall be payable monthly. The Servicing Fees shall be payable only at the time of and with respect to those Mortgage Loans for which payment is in fact made of the entire amount of the Monthly Payment or as otherwise provided in Section 3.04. The obligation of the Trust Fund (if any) to pay the Servicing Fees is limited as provided in Section 3.04. The aggregate of the Servicing Fees payable to the Servicer for any month with respect to the Mortgage Loans shall be reduced by any Prepayment Interest Shortfall Amount with respect to such month. Any Prepayment Interest Excess Amount shall be retained by, or paid to, the Servicer as a part of the Servicing Fee.

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 thereof except as specifically provided for herein.

Annual Audit Report.

On or before March 15th of each year, beginning with March 15, 2005, the Servicer shall, at its own expense, cause a firm of independent public accountants (who may also render other services to Servicer), which is a member of the American Institute of Certified Public Accountants, to furnish to the Seller, the Trustee, the Depositor and the Master Servicer (i) year-end audited (if available) financial statements of the Servicer and (ii) a statement to the effect that such firm has examined certain documents and records for the preceding fiscal year (or during the period from the date of commencement of such Servicer’s duties hereunder until the end of such preceding fiscal year in the case of the first such certificate) and that, on the basis of such examination conducted substantially in compliance with the Uniform Single Attestation Program for Mortgage Bankers (or such other attestation program as may be required by applicable law or regulation), such firm is of the opinion that Servicer’s overall servicing operations have been conducted in compliance with the Uniform Single Attestation Program for Mortgage Bankers (or such other attestation program as may be required by applicable law or regulation) except for such exceptions that, in the opinion of such firm, the Uniform Single Attestation Program for Mortgage Bankers requires it to report, in which case such exceptions shall be set forth in such statement.

Section 5.03

Annual Officer’s Certificate.

(a)

On or before March 15th of each year, beginning with March 15, 2005, the Servicer, at its own expense, will deliver to the Seller, the Depositor, the Trustee and the Master Servicer (i) a Servicing Officer’s certificate stating, as to each signer thereof, that (1) a review of the activities of the Servicer during such preceding fiscal year and of performance under this Agreement has been made under such officers’ supervision, and (2) to the best of such officers’ knowledge, based on such review, the Servicer has fulfilled all its obligations under this Agreement for such year, or, if there has been a default in the fulfillment of all such obligations, specifying each such default known to such officers and the nature and status thereof including the steps being taken by the Servicer to remedy such default and/or (ii) such other certificates as may be required under applicable law or regulation.

(b)

For so long as a certificate under the Xxxxxxxx-Xxxxx Act of 2002, as amended, (“Xxxxxxxx-Xxxxx”) is required to be given on behalf of the Trust Fund, no later than March 15th of each year (or if not a Business Day, the immediately preceding Business Day), beginning with March 15, 2005, or at any other time that the Master Servicer or the Depositor provides a certification pursuant to Xxxxxxxx-Xxxxx and upon thirty (30) days’ written request of such parties, an officer of the Servicer shall execute and deliver an Officer’s Certificate to the Master Servicer, the Trustee and the Depositor for the benefit of the Trust Fund, the Master Servicer and the Depositor and their officers, directors and affiliates, in the form of Exhibit E hereto or as may be required by applicable law or regulation.

(c)

The Servicer shall indemnify and hold harmless the Master Servicer, the Depositor and their respective officers, directors, agents and affiliates from and against any losses, damages, penalties, fines, forfeitures, reasonable legal fees and related costs, judgments and other costs and expenses arising out of or based upon a breach by the Servicer or any of its officers, directors, agents or affiliates of its obligations under this Section 5.03 or the negligence, bad faith or willful misconduct of the Servicer in connection therewith. If the indemnification provided for herein is unavailable or insufficient to hold harmless the Master Servicer and/or the Depositor, then the Servicer agrees that it shall contribute to the amount paid or payable by the Master Servicer and/or the Depositor as a result of the losses, claims, damages or liabilities of the Master Servicer and/or the Depositor in such proportion as is appropriate to reflect the relative fault of the Master Servicer and/or the Depositor on the one hand and the Servicer on the other in connection with a breach of the Servicer’s obligations under this Section 5.03 or the Servicer’s negligence, bad faith or willful misconduct in connection therewith.

Section 5.04

Transfers of Mortgaged Property.

The Servicer shall use its best efforts to enforce any “due-on-sale” provision contained in any Mortgage or Mortgage Note and to deny assumption by the person to whom the Mortgaged Property has been or is about to be sold whether by absolute conveyance or by contract of sale, and whether or not the Mortgagor remains liable on the Mortgage and the Mortgage Note; provided that, if in the Servicer's prudent business judgment, it determines that an assumption of the Mortgage Loan is in the best interests of the Trust Fund, it shall deliver notice of such determination to the Master Servicer and may permit such assumption if approved by the Master Servicer. When the Mortgaged Property has been conveyed by the Mortgagor, the Servicer shall, to the extent it has knowledge of such conveyance, so long as the Master Servicer has not consented to an assumption in accordance with the preceding sentence, exercise its rights to accelerate the maturity of such Mortgage Loan under the “due-on-sale” clause applicable thereto, provided, however, that the Servicer shall not be required to take such action if the Servicer, in its prudent business judgment, believes it is not in the best interests of the Trust Fund and shall not exercise such rights if prohibited by law from doing so or if the exercise of such rights would impair or threaten to impair any recovery under the related PMI Policy or LPMI Policy, if any.

If the Servicer reasonably believes it is unable under applicable law to enforce such “due-on-sale” clause or if the Master Servicer approves such assumption pursuant to the preceding paragraph, the Servicer shall enter into (i) an assumption and modification agreement with the person to whom such property has been conveyed, pursuant to which such person becomes liable under the Mortgage Note and the original Mortgagor remains liable thereon or (ii) in the event the Servicer is unable under applicable law to require that the original Mortgagor remain liable under the Mortgage Note and the Servicer has the prior consent of the primary mortgage guaranty insurer, a substitution of liability agreement with the owner of the Mortgaged Property pursuant to which the original Mortgagor is released from liability and the owner of the Mortgaged Property is substituted as Mortgagor and becomes liable under the Mortgage Note; provided that no such substitutions should be permitted unless such person satisfies the underwriting criteria of the Servicer and has a credit risk rating at least equal to that of the original Mortgagor. The Mortgage Loan, as assumed, shall conform in all respects to the requirements, representations and warranties of this Agreement. The Servicer shall notify the Master Servicer that any such assumption or substitution agreement has been contemplated by forwarding to the Master Servicer a copy of such assumption or substitution agreement (indicating the Mortgage File to which it relates). The Servicer shall forward an original copy of such agreement to the Custodian to be held by the Custodian with the other documents related to such Mortgage Loan. The Servicer shall be responsible for recording any such assumption or substitution agreements. In connection with any such assumption or substitution agreement, the Monthly Payment on the related Mortgage Loan shall not be changed but shall remain as in effect immediately prior to the assumption or substitution, the Mortgage Interest Rate, the stated maturity or the outstanding principal amount of such Mortgage Loan shall not be changed nor shall any required monthly payments of principal or interest be deferred or forgiven. Any assumption fee collected by the Servicer for entering into an assumption agreement shall be retained by the Servicer as additional servicing compensation. In connection with any such assumption, none of the Mortgage Interest Rate borne by the related Mortgage Note, the term of the Mortgage Loan or the outstanding principal amount of the Mortgage Loan shall be changed.

It is understood and agreed that the representations and warranties set forth in Section 6.01 shall survive the engagement of the Servicer to perform the servicing responsibilities as of the Closing Date or Servicing Transfer Date, as applicable, hereunder and the delivery of the Servicing Files to the Servicer and shall inure to the benefit of the Seller and the Trustee. Upon discovery by either the Servicer, the Master Servicer or the Seller of a breach of any of the foregoing representations and warranties which materially and adversely affects the ability of the Servicer to perform its duties and obligations under this Agreement or otherwise materially and adversely affects the value of the Mortgage Loans, the Mortgaged Property or the priority of the security interest on such Mortgaged Property or the interest of the Seller or the Trustee, the party discovering such breach shall give prompt written notice to the other.

The Servicer shall indemnify the Seller, the Depositor, the Trustee and the Master Servicer (and each of their respective directors, officers, employees and agents) and the Trust Fund, and hold them harmless against any and all Costs that any such indemnified party may sustain in any way related to (i) the failure of the Servicer to perform its duties and service the Mortgage Loans in material compliance with the terms of this Agreement (including, but not limited to its obligation to provide the certification pursuant to Section 5.03(b) hereunder) or for any inaccurate or misleading information provided in the certification required pursuant to Section 5.03(b) or (ii) the failure of the Servicer to cause any event to occur or not to occur which would have occurred or would not have occurred, as applicable, if the Servicer were applying Accepted Servicing Practices under this Agreement. The Servicer shall immediately notify the Seller, the Depositor, the Master Servicer, the Trustee or any other relevant party if a claim is made by a third party with respect to this Agreement or the Mortgage Loans, assume (with the prior written consent of the indemnified party in the event of an indemnified claim) the defense of any such claim and pay all expenses in connection therewith, including counsel fees, promptly pay, discharge and satisfy any judgment or decree which may be entered against it or any other party in respect of such claim and follow any written instructions received from such indemnifying party in connection with such claim. Subject to the Servicer’s indemnification pursuant to Section 6.02, or the failure of the Servicer to service and administer the Mortgage Loans in material compliance with the terms of this Agreement, the Trust Fund shall indemnify the Servicer and hold the Servicer harmless against any and all Costs that the Servicer may sustain in connection with any legal action relating to this Agreement, the Certificates or the origination or Servicing of the Mortgage Loans by any prior owner or servicer, other than any Costs incurred by reason of the Servicer’s willful misfeasance, bad faith or negligence in the performance of duties hereunder or by reason of its reckless disregard of obligations and duties hereunder.

Section 6.04

[Reserved].

Section 6.05

Indemnification with Respect to Certain Taxes and Loss of REMIC Status.

In the event that any REMIC fails to qualify as a REMIC, loses its status as a REMIC, or incurs federal, state or local taxes as a result of a prohibited transaction or prohibited contribution under the REMIC Provisions due to the negligent performance by the Servicer of its duties and obligations set forth herein, the Servicer shall indemnify the Holder of the related Residual Certificate, the Master Servicer, the Trustee and the Trust Fund (and each of their respective directors, officers, employees and agents) against any and all losses, claims, damages, liabilities or expenses (“Losses”) resulting from such negligence; provided, however, that the Servicer shall not be liable for any such Losses attributable to the action or inaction of the Trustee, the Depositor or the Holder of such Residual Certificate, as applicable, nor for any such Losses resulting from misinformation provided by the Holder of such Residual Certificate on which the Servicer has relied. The foregoing shall not be deemed to limit or restrict the rights and remedies of the Holder of such Residual Certificate, the Trustee and the Trust Fund now or hereafter existing at law or in equity or otherwise. Notwithstanding the foregoing, however, in no event shall the Servicer have any liability (1) for any action or omission that is taken in accordance with and in compliance with the express terms of, or which is expressly permitted by the terms of, this Agreement, (2) for any Losses other than arising out of a negligent performance by the Servicer of its duties and obligations set forth herein, and (3) for any special or consequential damages to Certificateholders (in addition to payment of principal and interest on the Certificates).

Section 6.06

Reporting Requirements of the Commission and Indemnification.

Notwithstanding any other provision of this Agreement, the Servicer shall (i) agree to such modifications and enter into such amendments to this Agreement as may be necessary, in the judgment of the Depositor, the Master Servicer and their respective counsel, to comply with any rules promulgated by the U.S. Securities and Exchange Commission (the “Commission”) and any interpretations thereof by the staff of the Commission (collectively, “SEC Rules”) and (ii) promptly upon request provide to the Depositor for inclusion in any periodic report required to be filed under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), such items of information regarding this Agreement and matters related to the Servicer, including as applicable (by way of example and not limitation), a description of any material litigation or governmental action or proceeding involving the Servicer or its affiliates (collectively, the “Servicer Information”), provided, that such information shall be required to be provided by the Servicer only to the extent that such shall be determined by the Depositor in its sole discretion and its counsel to be necessary or advisable to comply with any SEC Rules.

The Servicer hereby agrees to indemnify and hold harmless the Depositor, the Master Servicer, their respective officers and directors and each person, if any, who controls the Depositor or Master Servicer within the meaning of Section 15 of the Securities Act of 1933, as amended (the “Act”), or Section 20 of the Exchange Act, from and against any and all losses, claims, expenses, damages or liabilities to which the Depositor, the Master Servicer, their respective officers or directors and any such controlling person may become subject under the Act or otherwise, as and when such losses, claims, expenses, damages or liabilities are incurred, insofar as such losses, claims, expenses, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Servicer Information or arise out of, or are based upon, the omission or alleged omission to state therein any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, and will reimburse the Depositor, the Master Servicer, their respective officers and directors and any such controlling person for any legal or other expenses reasonably incurred by it or any of them in connection with investigating or defending any such loss, claim, expense, damage, liability or action, as and when incurred; provided, however, that the Servicer shall be liable only insofar as such untrue statement or alleged untrue statement or omission or alleged omission relates solely to the information in the Servicer Information furnished to the Depositor or Master Servicer by or on behalf of the Servicer specifically in connection with this Agreement.

ARTICLE VII.

THE SERVICER

Section 7.01

Merger or Consolidation of the Servicer.

The Servicer shall keep in full effect its existence, rights and franchises as a corporation, and shall obtain and preserve its qualification to do business as a foreign entity in each jurisdiction in which such qualification is or shall be necessary to protect the validity and enforceability of this Agreement or any of the Mortgage Loans and to perform its duties under this Agreement.

Any Person into which the Servicer may be merged or consolidated, or any corporation resulting from any merger, conversion 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 shall be an institution (i) having a net worth of not less than $25,000,000, and (ii) which is a Xxxxxx Mae or Xxxxxxx Mac approved servicer in good standing.

Section 7.02

Limitation on Liability of the Servicer and Others.

Neither the Servicer nor any of the directors, officers, employees or agents of the Servicer shall be under any liability to the Seller, the Master Servicer or the Trustee 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 Servicer or any such person against any breach of warranties or representations made herein, or failure to perform its obligations in strict compliance with any standard of care set forth in this Agreement, or any liability which would otherwise be imposed by reason of any breach of the terms and conditions of this Agreement. The Servicer and any director, officer, employee or agent of the 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 Servicer shall not be under any obligation to appear in, prosecute or defend any legal action which is not incidental to its duties to service the Mortgage Loans in accordance with this Agreement and which in its opinion may involve it in any expense or liability, provided, however, that the Servicer may, with the consent of the Master Servicer, undertake any such action which it may deem necessary or desirable in respect of this Agreement and the rights and duties of the parties hereto. In such event, the Servicer shall be entitled to reimbursement from the Trust Fund for the reasonable legal expenses and costs of such action.

Section 7.03

Limitation on Resignation and Assignment by the Servicer.

The Seller has entered into this Agreement with the Servicer in reliance upon the independent status of the Servicer, and the representations as to the adequacy of its servicing facilities, plant, personnel, records and procedures, its integrity, reputation and financial standing, and the continuance thereof. Therefore, the Servicer shall neither assign its rights under this Agreement or the servicing hereunder nor delegate its duties hereunder or any portion thereof, or sell or otherwise dispose of all or substantially all of its property or assets without, in each case, the prior written consent of the Seller (as owner of the servicing rights relating to the Mortgage Loans) and the Master Servicer, which consent, in the case of an assignment of rights or delegation of duties, shall be granted or withheld in the discretion of the Seller and the Master Servicer, and which consent, in the case of a sale or disposition of all or substantially all of the property or assets of the Servicer, shall not be unreasonably withheld; provided, that in each case, there must be delivered to the Master Servicer and the Trustee a letter from each Rating Agency to the effect that such transfer of servicing or sale or disposition of assets will not result in a qualification, withdrawal or downgrade of the then-current rating of any of the Certificates. Notwithstanding the foregoing, the Servicer, without the consent of the Seller (as owner of the servicing rights relating to the Mortgage Loans), the Master Servicer or the Trustee, may retain third party contractors to perform certain servicing and loan administration functions, including without limitation, hazard insurance administration, tax payment and administration, flood certification and administration, collection services and similar functions; provided, that the retention of such contractors by Servicer shall not limit the obligation of the Servicer to service the Mortgage Loans pursuant to the terms and conditions of this Agreement.

The Servicer shall not resign from the obligations and duties hereby imposed on it except by mutual consent of the Servicer and the Master Servicer or upon the determination that its duties hereunder are no longer permissible under applicable law and such incapacity cannot be cured by the Servicer. Any such determination permitting the resignation of the Servicer shall be evidenced by an Opinion of Counsel to such effect delivered to the Master Servicer and the Trustee which Opinion of Counsel shall be in form and substance acceptable to the Master Servicer and the Trustee. No such resignation shall become effective until a successor shall have assumed the Servicer’s responsibilities and obligations hereunder in the manner provided in Section 9.01.

Without in any way limiting the generality of this Section 7.03, in the event that the Servicer either shall assign this Agreement or the servicing responsibilities hereunder or delegate its duties hereunder or any portion thereof or sell or otherwise dispose of all or substantially all of its property or assets, without the prior written consent of the Seller, the Trustee and the Master Servicer, then the Seller, the Trustee or the Master Servicer shall have the right to terminate this Agreement upon notice given as set forth in Section 8.01, without any payment of any penalty or damages and without any liability whatsoever to the Servicer or any third party.

Section 7.04

Subservicing Agreements and Successor Subservicer.

(a)

The Servicer may enter into subservicing agreements for any servicing and administration of the Mortgage Loans with any institution which (i) is an approved Xxxxxx Xxx or Xxxxxxx Mac Seller/Servicer and (ii) which represents and warrants that it is in compliance with the laws of each state as necessary to enable it to perform its obligations under such subservicing agreement. For this purpose, subservicing shall not be deemed to include outsourcing routine tasks to third parties including, but not limited to, taxes, insurance, property inspection, reconveyance, collection or brokering REO Property. The Servicer shall give prior written notice to the Master Servicer and the Trustee of the appointment of any subservicer and shall furnish to the Master Servicer a copy of such subservicing agreement. For purposes of this Agreement, the Servicer shall be deemed to have received payments on Mortgage Loans immediately upon receipt by any subservicer of such payments. Any such subservicing agreement shall be consistent with and not violate the provisions of this Agreement. Each subservicing agreement shall provide that a successor servicer shall have the option to terminate such agreement without payment of any fees if the predecessor servicer is terminated or resigns.

(b)

The Servicer may terminate any subservicing agreement to which it is a party in accordance with the terms and conditions of such subservicing agreement and either itself directly service the related Mortgage Loans or enter into a subservicing agreement with a successor subservicer that qualifies under Section 7.04(a).

(c)

Notwithstanding any subservicing agreement or 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 primarily liable to the Trustee, the Master Servicer and the Certificateholders for the servicing and administering of the Mortgage Loans in accordance with the provisions hereof 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 the Mortgage Loans. The Servicer shall be entitled to enter into any agreement with a subservicer for indemnification of the Servicer by such subservicer and nothing contained in this Agreement shall be deemed to limit or modify such indemnification.

ARTICLE VIII.

TERMINATION

Section 8.01

Termination for Cause.

This Agreement shall be terminable at the option of the Seller or the Master Servicer if any of the following events of default exist on the part of the Servicer:

(i)

any failure by the Servicer to remit to the Master Servicer any payment required to be made under the terms of this Agreement which continues unremedied for a period of two Business Days after the date upon which written notice of such failure, requiring the same to be remedied, shall have been given to the Servicer by the Master Servicer; or

(ii)

failure by the Servicer duly to observe or perform in any material respect any other of the covenants or agreements on the part of the Servicer set forth in this Agreement which continues unremedied for a period of 30 days; or

(iii)

failure by the Servicer to maintain its license to do business or service residential mortgage loans in any jurisdiction, if required by such jurisdiction, where the Mortgaged Properties are located; or

(iv)

a decree or order of a court or agency or supervisory authority having jurisdiction for the appointment of a conservator or receiver or liquidator in any insolvency, readjustment of debt, including bankruptcy, marshaling of assets and liabilities or similar proceedings, or for the winding-up or liquidation of its affairs, shall have been entered against the Servicer and such decree or order shall have remained in force undischarged or unstayed for a period of 60 days; or

(v)

the Servicer shall consent to the appointment of a conservator or receiver or liquidator in any insolvency, readjustment of debt, marshaling of assets and liabilities or similar proceedings of or relating to the Servicer or of or relating to all or substantially all of its property; or

(vi)

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, bankruptcy or reorganization statute, make an assignment for the benefit of its creditors, voluntarily suspend payment of its obligations or cease its normal business operations for three Business Days; or

(vii)

the Servicer ceases to meet the qualifications of a Xxxxxx Xxx or Xxxxxxx Mac seller/servicer; or

(viii)

the Servicer attempts to assign the servicing of the Mortgage Loans or its right to servicing compensation hereunder or the Servicer attempts to sell or otherwise dispose of all or substantially all of its property or assets or to assign this Agreement or the servicing responsibilities hereunder or to delegate its duties hereunder or any portion thereof (to other than a third party in the case of outsourcing routine tasks including, but not limited to, taxes, insurance, property inspection, reconveyance, collection or brokering REO Property), in each case without complying fully with the provisions of Section 7.03.

In each and every such case, so long as an event of default shall not have been remedied, in addition to whatever rights the Seller or the Master Servicer may have at law or equity to damages, including injunctive relief and specific performance, the Seller or the Master Servicer, by notice in writing to the Servicer, may terminate all the rights and obligations of the Servicer under this Agreement and in and to the servicing contract established hereby and the proceeds thereof.

Upon receipt by the Servicer of such written notice, all authority and power of the Servicer under this Agreement, whether with respect to the Mortgage Loans or otherwise, shall pass to and be vested in a successor Servicer appointed by the Seller and the Master Servicer. Upon written request from the Seller, the Servicer shall prepare, execute and deliver to the successor entity designated by the Seller any and all documents and other instruments, place in such successor’s possession all Servicing Files, and do or cause to be done all other acts or things necessary or appropriate to effect the purposes of such notice of termination, including but not limited to the transfer and endorsement or assignment of the Mortgage Loans and related documents, at the Servicer’s sole expense. The Servicer shall cooperate with the Seller and the Master Servicer and such successor in effecting the termination of the Servicer’s responsibilities and rights hereunder, including without limitation, the transfer to such successor for administration by it of all cash amounts which shall at the time be credited by the Servicer to the Custodial Account or Escrow Account or thereafter received with respect to the Mortgage Loans.

By a written notice, the Seller and the Master Servicer may waive any default by the Servicer in the performance of its obligations hereunder and its consequences. 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 thereon except to the extent expressly so waived.

Section 8.02

Termination Without Cause.

This Agreement shall terminate upon: (i) the later of (a) the distribution of the final payment or liquidation proceeds on the last Mortgage Loan to the Master Servicer (or advances by the Servicer for the same), and (b) the disposition of all REO Property acquired upon foreclosure of the last Mortgage Loan and the remittance of all funds due hereunder, (ii) mutual consent of the Servicer, the Seller (as owner of the servicing rights relating to the Mortgage Loans), the Trustee and the Master Servicer in writing or (iii) at the sole discretion of the Seller (acting in its capacity as owner of the servicing rights relating to the Mortgage Loans). Any such termination pursuant to clause (iii) above shall be with 30 days’ prior notice, in writing and delivered to the Trustee, the Master Servicer and the Servicer by registered mail to the addresses set forth in Section 9.03 of this Agreement (in the case of the Servicer) or in the Trust Agreement (in the case of the Trustee or the Master Servicer). The Servicer shall comply with the termination procedures set forth in Sections 7.03, 8.01 and 9.01 hereof. The Master Servicer or the Trustee shall have no right to terminate the Servicer pursuant to this Section 8.02. In connection with a termination by the Seller pursuant to clause (iii) of this Section 8.02, the Servicer shall be reimbursed for all unreimbursed out-of-pocket Servicing Advances, Monthly Advances and Servicing Fees and other reasonable and necessary out-of-pocket costs associated with any transfer of servicing at the time of such transfer of servicing. Any invoices received by the Servicer after termination will be forwarded to the Seller or the successor servicer for payment within thirty (30) days of receipt from the Servicer.

ARTICLE IX.

MISCELLANEOUS PROVISIONS

Section 9.01

Successor to the Servicer.

Simultaneously with the termination of the Servicer’s responsibilities and duties under this Agreement (a) pursuant to Sections 6.02, 7.03, 8.01 or 8.02(ii), the Master Servicer shall (i) succeed to and assume all of the Servicer’s responsibilities, rights, duties and obligations under this Agreement, or (ii) appoint a successor having the characteristics set forth in clauses (i) and (ii) of Section 7.01 and which shall succeed to all rights and assume all of the responsibilities, duties and liabilities of the Servicer under this Agreement simultaneously with the termination of the Servicer’s responsibilities, duties and liabilities under this Agreement; or (b) pursuant to a termination under Section 8.02(iii), the Seller (as owner of the servicing rights relating to the Mortgage Loans) shall appoint a successor having the characteristics set forth in clauses (i) and (ii) of Section 7.01 and which shall succeed to all rights and assume all of the responsibilities, duties and liabilities of the Servicer under this Agreement simultaneously with the termination of the Servicer’s responsibilities, duties and liabilities under this Agreement. Any successor to the Servicer shall be subject to the approval of the Master Servicer and, to the extent required by the Trust Agreement, the Trustee and such successor, shall be a member in good standing of the MERS system (if any of the Mortgage Loans are MERS Eligible Mortgage Loans, unless such Mortgage Loans are withdrawn from MERS and Assignments of Mortgage are recorded in favor of the Trustee at the expense of the successor Servicer). Any approval of a successor servicer by the Master Servicer and, to the extent required by the Trust Agreement, the Trustee, shall, if the successor servicer is not at that time a servicer of other Mortgage Loans for the Trust Fund, be conditioned upon the receipt by the Master Servicer and the Trustee of a letter from each Rating Agency to the effect that such transfer of servicing will not result in a qualification, withdrawal or downgrade of the then-current rating of any of the Certificates. In connection with such appointment and assumption, the Master Servicer or the Seller, as applicable, may make such arrangements for the compensation of such successor out of payments on Mortgage Loans as it and such successor shall agree, provided, however, that no such compensation shall be in excess of that permitted the Servicer under this Agreement. In the event that the Servicer’s duties, responsibilities and liabilities under this Agreement should be terminated pursuant to the aforementioned sections, the Servicer shall discharge such duties and responsibilities during the period from the date it acquires knowledge of such termination until the effective date thereof with the same degree of diligence and prudence which it is obligated to exercise under this Agreement, and shall take no action whatsoever that might impair or prejudice the rights or financial condition of its successor. The resignation or removal of the Servicer pursuant to the aforementioned sections shall not become effective until a successor shall be appointed pursuant to this Section 9.01 and shall in no event relieve the Servicer of the representations and warranties made pursuant to Sections 6.01 and the remedies available to the Master Servicer and the Seller under Section 6.02 and 6.03, it being understood and agreed that the provisions of such Sections 6.01, 6.02 and 6.03 shall be applicable to the Servicer notwithstanding any such resignation or termination of the Servicer, or the termination of this Agreement. Neither the Master Servicer, in its capacity as successor servicer, nor any other successor servicer, shall be responsible for the lack of information and/or documents that are not transferred to it by the Servicer and that it cannot otherwise obtain through reasonable efforts.

Within a reasonable period of time, but in no event longer than 30 days of the appointment of a successor entity, the Servicer shall prepare, execute and deliver to the successor entity any and all documents and other instruments, place in such successor’s possession all Servicing Files, and do or cause to be done all other acts or things necessary or appropriate to effect the purposes of such notice of termination, including but not limited to the transfer and endorsement of the Mortgage Notes and related documents, and the preparation and recordation of Assignments of Mortgage. The Servicer shall cooperate with the Trustee, the Master Servicer or the Seller, as applicable, and such successor in effecting the termination of the Servicer’s responsibilities and rights hereunder and the transfer of servicing responsibilities to the successor Servicer, including without limitation, the transfer to such successor for administration by it of all cash amounts which shall at the time be credited by the Servicer to the Custodial Account or Escrow Account or thereafter received with respect to the Mortgage Loans.

Any successor appointed as provided herein shall execute, acknowledge and deliver to the Trustee, the Servicer, the Master Servicer and the Seller an instrument (i) accepting such appointment, wherein the successor shall make the representations and warranties set forth in Section 6.01 (including a representation that the successor Servicer is a member of MERS, unless none of the Mortgage Loans are MERS Mortgage Loans or MERS Eligible Mortgage Loans or any such Mortgage Loans have been withdrawn from MERS and Assignments of Mortgage are recorded in favor of the Trustee) and (ii) an assumption of the due and punctual performance and observance of each covenant and condition to be performed and observed by the Servicer under this Agreement, whereupon such successor shall become fully vested with all the rights, powers, duties, responsibilities, obligations and liabilities of the Servicer, with like effect as if originally named as a party to this Agreement. Any termination or resignation of the Servicer or termination of this Agreement pursuant to Sections 6.02, 7.03, 8.01 or 8.02 shall not affect any claims that the Master Servicer or the Trustee may have against the Servicer arising out of the Servicer’s actions or failure to act prior to any such termination or resignation. In addition, in the event any successor servicer is appointed pursuant to Section 8.02(iii) of this Agreement, such successor servicer must satisfy the conditions relating to the transfer of servicing set forth in the Trust Agreement.

The Servicer shall deliver promptly to the successor servicer the funds in the Custodial Account and Escrow Account (and any funds thereafter received by it with respect to the Mortgage Loans) and all Mortgage Loan documents and related documents and statements held by it hereunder and the Servicer shall account for all funds and shall execute and deliver such instruments and do such other things as may reasonably be required to more fully and definitively vest in the successor all such rights, powers, duties, responsibilities, obligations and liabilities of the Servicer.

Upon a successor’s acceptance of appointment as such, the Servicer shall notify the Trustee, the Seller and Master Servicer of such appointment in accordance with the procedures set forth in Section 9.03.

Section 9.02

Costs.

Xxxxxx Holdings shall pay the legal fees and expenses of its attorneys. Costs and expenses incurred in connection with the transfer of the servicing responsibilities, including fees for delivering Servicing Files, shall be paid by Xxxxxx Holdings.

Section 9.04

Severability Clause.

Any part, provision, representation or warranty of this Agreement which is prohibited or which is held to be void or unenforceable shall be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof. Any part, provision, representation or warranty of this Agreement which is prohibited or unenforceable or is held to be void or unenforceable in any jurisdiction shall be ineffective, as to such jurisdiction, to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction as to any Mortgage Loan shall not invalidate or render unenforceable such provision in any other jurisdiction. To the extent permitted by applicable law, the parties hereto waive any provision of law which prohibits or renders void or unenforceable any provision hereof. If the invalidity of any part, provision, representation or warranty of this Agreement shall deprive any party of the economic benefit intended to be conferred by this Agreement, the parties shall negotiate, in good-faith, to develop a structure the economic effect of which is as close as possible to the economic effect of this Agreement without regard to such invalidity.

Section 9.05

No Personal Solicitation.

From and after the Closing Date, the Servicer hereby agrees that it will not take any action or permit or cause any action to be taken by any of its agents or affiliates, or by any independent contractors on the Servicer’s behalf, to personally, by telephone or mail, solicit the borrower or obligor under any Mortgage Loan (on a targeted basis) for any purposes of prepayment, refinancing or modification of the related Mortgage Loan, provided, however, that this limitation shall not prohibit Servicer from soliciting such Mortgagor for purposes of prepayment, refinance or modification of any loan owned or serviced by Servicer other than a Mortgage Loan. Notwithstanding the foregoing, it is understood and agreed that, among other marketing activities, promotions and solicitations undertaken by the Servicer which are directed of the general public at large or which are directed generally to a segment of the then existing customers of the Servicer or any of its affiliates (including, without limitation, the mailing of promotional materials to the Servicer’s or its affiliates’ deposit customers by inserting such materials into customer account statements, mass mailings based on commercially acquired mailing lists and newspaper, radio and television advertisements and solicitations made on the basis of information acquired by the Servicer or its affiliates that indicates that a borrower may be planning to refinance) shall not constitute solicitation under this section. In the event the Servicer does refinance any Mortgage Loan as a result of a violation of the requirements set forth in this Section 9.05, the Servicer hereby agrees to pay to the Trust Fund an amount equal to the difference, if any, between the amount that the Trust Fund would have received if it had sold the Mortgage Loan to a third party, and the proceeds received by the Trust Fund as a result of such refinancing.

Section 9.06

Counterparts.

This Agreement may be executed simultaneously in any number of counterparts. Each counterpart shall be deemed to be an original, and all such counterparts shall constitute one and the same instrument.

Section 9.07

THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REFERENCE TO ITS CONFLICT OF LAW PROVISIONS (OTHER THAN SECTION 5-1401 OF THE GENERAL OBLIGATIONS LAW), AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.

Section 9.08

Further Agreements.

The Seller and the Servicer each agree to execute and deliver to the other such reasonable and appropriate additional documents, instruments or agreements as may be necessary or appropriate to effectuate the purposes of this Agreement.

Section 9.09

Intention of the Parties.

Accordingly, the parties hereby acknowledge that the Trust Fund remains the sole and absolute owner of the Mortgage Loans and all rights (other than the servicing rights) related thereto.

Section 9.10

Successors and Assigns; Assignment of Servicing Agreement.

This Agreement shall bind and inure to the benefit of and be enforceable by the Servicer, the Seller, the Trustee and the Master Servicer and their respective successors and assigns.

Section 9.11

Assignment by the Seller.

The Seller shall have the right, upon notice to but without the consent of the Servicer, to assign, in whole or in part, its interest under this Agreement to the Depositor, which in turn shall assign such rights to the Trustee, and the Trustee then shall succeed to all rights (but not the obligations, except as set forth in the Trust Agreement) of the Seller under this Agreement (and in performing hereunder, the Trustee shall have all of the rights, protections and immunities afforded to it under the Trust Agreement).
