On or before the Closing Date or Servicing Transfer Date, as applicable, the Seller shall cause to be delivered to the Servicer, the Servicing Files with respect to the Mortgage Loans listed on the Mortgage Loan Schedule. The Servicer shall maintain a Servicing File with respect to each Mortgage Loan in order to service such Mortgage Loans pursuant to this Agreement and each Servicing File delivered to the Servicer shall be held in trust by the Servicer for the benefit of the Trustee; provided, however, that the Servicer shall have no liability for any Servicing Files (or portions thereof) not delivered by the Seller. The Servicer’s possession of any portion of the Mortgage Loan documents shall be at the will of the Trustee for the sole purpose of facilitating servicing of the related Mortgage Loan pursuant to this Agreement, and such retention and possession by the Servicer shall be in a custodial capacity only. The ownership of each Mortgage Note, Mortgage, and the contents of the Servicing File shall be vested in the Trustee and the ownership of all records and documents with respect to the related Mortgage Loan prepared by or which come into the possession of the Servicer shall immediately vest in the Trustee and shall be retained and maintained, in trust, by the Servicer at the will of the Trustee in such custodial capacity only. The portion of each Servicing File retained by the Servicer pursuant to this Agreement shall be appropriately marked to clearly reflect the ownership of the related Mortgage Loan by the Trustee. The Servicer shall release from its custody the contents of any Servicing File retained by it only in accordance with this Agreement.

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 or through the utilization of a Subservicer or Subcontractor, 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 Servicer shall service the Mortgage Loans in accordance with the guidelines of the applicable agency guides and shall comply with the rules and regulations of the applicable agency. The Servicer shall be responsible for any and all acts of a Subservicer or Subcontractor and the Servicer’s utilization of such Subservicer or Subcontractor shall in no way relieve the liability of the Servicer under this Agreement.

Consistent with the terms of this Agreement, the Servicer may waive, modify or vary any term of any Mortgage Loan or consent to the postponement of strict compliance with any such term or in any manner grant indulgence to any Mortgagor if in the Servicer’s reasonable and prudent determination such waiver, modification, postponement or indulgence is not materially adverse to the Trust Fund; provided, however, that unless the Servicer has obtained the prior written consent of the Master Servicer and the NIMS Insurer, the Servicer shall not permit any modification with respect to any Mortgage Loan that would change the Mortgage Interest Rate (except for modifications relating to Relief Act Reductions), 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 (a) 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 (b) 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 3.04. 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; provided, further, that upon the full release or discharge, the Servicer shall notify the related Custodian of the related Mortgage Loan of such full release or discharge. Upon the reasonable request of the Servicer, the Trustee shall execute and deliver to the Servicer with 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; provided that the Trustee shall not be liable for the actions of the Servicer under such powers of attorney unless such actions of the Servicer are performed at, and in accordance with, the written direction of the Trustee. 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.

The Servicer is authorized, without the prior approval of the Trustee, to consent to the refinancing of any Superior Lien on Mortgaged Property, provided that (i) the resulting Combined Loan-to-Value Ratio of such mortgage loan is no higher than the Combined Loan-to-Value Ratio prior to such refinancing; (ii) the interest rate, or in the case of any Superior Lien which is an adjustable rate mortgage loan, the applicable Maximum Rate which can be charged under the related Mortgage Note is no more than 2.00% higher than the interest rate or the Maximum Rate, as the case may be, on the mortgage loan evidencing the existing Superior Lien immediately prior to the date of such refinancing; (iii) the mortgage loan evidencing the Superior Lien is not subject to negative amortization and (iv) the Monthly Payment on the mortgage loan evidencing the existing Superior Lien has not increased since the Due Date immediately prior to the date of such refinancing.

The Servicer shall not without the Trustee’s written consent: (i) initiate any action, suit or proceedings solely under the Trustee’s name without indicating the Servicer’s, representative capacity or (ii) take any action with the intent to cause, and which actually does cause, the Trustee to be registered to do business in any state. The Servicer shall indemnify the Trustee for any and all costs, liabilities and expenses incurred by the Trustee in connection with the negligent or willful misuse of such powers of attorney by the Servicer.

In servicing and administering the Mortgage Loans, the Servicer shall employ procedures (including collection procedures) and exercise the same care that it would employ and exercise in servicing and administering similar 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.

Section 3.02.

Collection and Liquidation of Mortgage Loans.

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. The Servicer shall also apply payments of interest and principal against any Simple Interest Mortgage Loans using the Simple Interest Method.

The Servicer shall use its best efforts, consistent with the procedures that the Servicer would use in servicing similar mortgage loans for its own account, to foreclose upon or otherwise comparably convert the ownership of such Mortgaged Properties as come into and continue in default and as to which no satisfactory arrangements can be made for collection of delinquent payments pursuant to Section 3.01. The Servicer shall use its best efforts to realize upon defaulted Mortgage Loans in such a manner as will maximize the receipt of principal and interest by the Trustee, taking into account, among other things, the timing of foreclosure proceedings. The foregoing is subject to the provisions that, in any case in which Mortgaged Property shall have suffered damage, the Servicer shall not be required to expend its own funds toward the restoration of such property unless it shall determine in its discretion (i) that such restoration will increase the proceeds of liquidation of the related Mortgage Loan to the Master Servicer after reimbursement to itself for such expenses, and (ii) that such expenses will be recoverable by the Servicer through Insurance Proceeds or Liquidation Proceeds from the related Mortgaged Property. In the event that any payment due under any Mortgage Loan and not postponed pursuant to Section 3.01 is not paid when the same becomes due and payable, or in the event the Mortgagor fails to perform any other covenant or obligation under the Mortgage Loan and such failure continues beyond any applicable grace period, the Servicer shall take such action as (1) the Servicer would take for other institutional investors under similar circumstances with respect to a similar mortgage loan, (2) shall be consistent with Accepted Servicing Practices, (3) the Servicer shall determine prudently to be in the best interest of the Trust Fund, and (4) is consistent with any related PMI Policy or LPMI Policy. In the event that any payment due under any Mortgage Loan is not postponed pursuant to Section 3.01 and remains delinquent for a period of ninety (90) days or any other default continues for a period of ninety (90) days beyond the expiration of any grace or cure period, the Servicer shall commence foreclosure proceedings, provided that prior to commencing foreclosure proceedings, the Servicer shall notify the Master Servicer (who will notify the Trustee and the NIMS Insurer) in writing of the Servicer’s intention to do so. In such connection, the Servicer shall be responsible for advancing all costs and expenses incurred by it in any such proceedings; provided, however, that it shall be entitled to reimbursement thereof from the related Mortgaged Property, as contemplated in Section 3.04.

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 “Xxxxx Fargo Bank, N.A. in trust for U.S. Bank National Association, as Trustee for Structured Asset Investment Loan Trust, 2006-4.” The Custodial Account shall be an Eligible Deposit Account established with an Eligible Institution. 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 hereto. A copy of such certification shall be furnished to the Master Servicer no later than 30 days after the Closing Date (and to the NIMS Insurer upon request).

The Servicer shall deposit in the Custodial Account within two (2) Business Days of receipt and retain therein, the following collections received by the Servicer and payments made by the Servicer after the Cut-off Date (other than scheduled payments of principal and interest due on or before the Cut-off Date) or the Servicing Transfer Date, as applicable:

(ix)

any amounts received by the Servicer under a PMI or LPMI Policy; and

(xv)

the Seller Remittance Amount.

The Servicer shall also deposit from its own funds into the Custodial Account, without the right to reimbursement, except from Net Simple Interest Excess, an amount equal to any Net Simple Interest Shortfall (to the extent not offset by Net Simple Interest Excess) for the related Due Period and remit such funds to the Master Servicer pursuant to Section 4.01.

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 Xxxxx Fargo 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.

(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 which 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.

Section 3.08.

(Reserved.)

Section 3.09.

Payment of Taxes, Insurance and Other Charges.

(a)

With respect to each Mortgage Loan which provides for Escrow Payments, the Servicer shall maintain accurate records of those escrowed items which are or may become a lien upon the Mortgaged Property and the status of fire and hazard insurance coverage and shall obtain, from time to time, all bills for the payment of such charges (including renewal premiums) (“Property Charges”) 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 assumes full responsibility for the timely payment of all such bills and 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 the Servicer shall make advances from its own funds to effect such payments.

(b)

To the extent that a Mortgage Loan does not provide for Escrow Payments, the Servicer shall make advances from its own funds to effect payment of all Property Charges upon receipt of notice of any failure to pay on the part of the Mortgagor, or at such other time as the Servicer determines to be in the best interest of the Trust Fund, provided that in any event the Servicer shall pay such charges on or before the earlier of (a) any date by which payment is necessary to preserve the lien status of the Mortgage or (b) the date which is ninety days after the date on which such charges first became due. The Servicer shall pay any late fee or penalty which is payable due to any delay in payment of any Property Charge after the earlier to occur of (a) the date on which the Servicer receives notice of the failure of the Mortgagor to pay such Property Charge or (b) the date which is ninety days after the date on which such charges first became due.

Section 3.10.

Protection of Accounts.

The Servicer may transfer the Custodial Account or any Escrow Account to a different Eligible Institution from time to time and shall give notice to the Master Servicer of any change in the location of the Custodial Account no later than 30 days after any such transfer is made and deliver to the Master Servicer, upon request, a certification notice in the form of Exhibit B or Exhibit C, as applicable, with respect to such Eligible Institution; 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.

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.

Section 3.11.

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 acceptable under Xxxxxx Xxx or Xxxxxxx Mac guidelines 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 lesser of (i) the replacement value of the improvements securing such Mortgage Loan and (ii) the greater of (a) the outstanding principal balance of the Mortgage Loan and (b) 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 acceptable to Xxxxxx Mae or Xxxxxxx Mac 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 Mae 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 immediately force place the required flood insurance on the Mortgagor’s behalf.

If a Mortgage Loan is secured by a unit in a condominium project, the Servicer shall verify that the coverage required of the owner’s association, including hazard, flood, liability and fidelity coverage, is being maintained in accordance with, at a minimum, the then current Xxxxxx Xxx or Xxxxxxx Mac requirements.

In the event that the Master Servicer or the Servicer shall determine that the Mortgaged Property should be insured against loss or damage by hazards and risks not covered by the insurance required to be maintained by the Mortgagor pursuant to the terms of the Mortgage, the Servicer shall communicate and consult with the Mortgagor with respect to the need for such insurance and bring to the Mortgagor’s attention the desirability of protection of the Mortgaged Property.

All policies required hereunder shall name the Servicer as loss payee and shall be endorsed with standard or union mortgagee clauses, without contribution, which shall provide for at least 30 days prior written notice of any cancellation, reduction in amount or material change in coverage.

The Servicer shall not interfere with the Mortgagor’s freedom of choice in selecting either his insurance carrier or agent, provided, however, that the Servicer shall not accept any such insurance policies from insurance companies unless such companies are acceptable to Xxxxxx Mae or Xxxxxxx Mac and are licensed to do business in the jurisdiction in which the Mortgaged Property is located. The Servicer shall determine that such policies provide sufficient risk coverage and amounts, that they insure the property owner, and that they properly describe the property address. The Servicer shall furnish to the Mortgagor a formal notice of expiration of any such insurance in sufficient time for the Mortgagor to arrange for renewal coverage by the expiration date.

Pursuant to Section 3.03, any amounts collected by the Servicer under any such policies (other than amounts to be deposited in the Escrow Account and applied to the restoration or repair of the related Mortgaged Property, or property acquired in liquidation of the Mortgage Loan, or to be released to the Mortgagor, in accordance with the Servicer’s normal servicing procedures as specified in Section 3.15) shall be deposited in the Custodial Account subject to withdrawal pursuant to Section 3.04.

Notwithstanding anything set forth in the preceding paragraph, the Servicer agrees to indemnify the Trustee, the NIMS Insurer, the Certificateholders, the Master Servicer and the Trust Fund for any claims, losses, damages, penalties, fines, forfeitures, legal fees and related costs, judgments and any other costs, fees and expenses that any such indemnified party may sustain in any way related to the failure of the Mortgagor (or the Servicer) to maintain hazard insurance or flood insurance with respect to the related Mortgaged Property which complies with the requirements of this section.

Section 3.12.

Maintenance of Mortgage Impairment Insurance.

In the event that 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, then, to the extent such policy provides coverage in an amount equal to the amount required pursuant to Section 3.11 and otherwise complies with all other requirements of Section 3.11, it shall conclusively be deemed to have satisfied its obligations as set forth in Section 3.11. Any amounts collected by the Servicer under any such policy relating to a Mortgage Loan shall be deposited in the Custodial Account subject to withdrawal pursuant to Section 3.04. 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 3.11, 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 deposited from the Servicer’s funds, without reimbursement therefor. Upon request of the Master Servicer, the Trustee or the NIMS Insurer, the Servicer shall cause to be delivered to such person a certificate of insurance of such policy and a statement from the insurer thereunder that such policy shall in no event be terminated or materially modified without 30 days’ prior written notice to the Master Servicer, the Trustee and the NIMS Insurer.

Section 3.13.

Maintenance of Fidelity Bond and Errors and Omissions Insurance.

The Servicer shall maintain with responsible companies, at its own expense, a blanket Fidelity Bond and an Errors and Omissions Insurance Policy, with broad coverage on all officers, employees or other persons acting in any capacity requiring such persons to handle funds, money, documents or papers relating to the Mortgage Loans (“Servicer Employees”). Any such Fidelity Bond and Errors and Omissions Insurance Policy shall be in the form of the Mortgage Banker’s Blanket Bond and shall protect and insure the Servicer against losses, including forgery, theft, embezzlement, fraud, errors and omissions and negligent acts of such Servicer Employees. Such Fidelity Bond and Errors and Omissions Insurance Policy also shall protect and insure the Servicer against losses in connection with the release or satisfaction of a Mortgage Loan without having obtained payment in full of the indebtedness secured thereby. No provision of this Section 3.13 requiring such Fidelity Bond and Errors and Omissions Insurance Policy shall diminish or relieve the Servicer from its duties and obligations as set forth in this Agreement. The minimum coverage under any such bond and insurance policy shall be at least equal to the corresponding amounts required by the Xxxxxx Xxx Guides or by Xxxxxxx Mac in the Xxxxxxx Xxx Xxxxxxx’ & Servicers’ Guide, or as otherwise acceptable to Xxxxxx Mae and Xxxxxxx Mac. Upon the request of the Master Servicer, the Trustee or the NIMS Insurer, the Servicer shall cause to be delivered to such party a certificate of insurance for such fidelity bond and insurance policy and a statement from the surety and the insurer that such fidelity bond and insurance policy shall in no event be terminated or materially modified without 30 days’ prior written notice to the Master Servicer, the Trustee and the NIMS Insurer.

Section 3.14.

Inspections.

The Servicer shall inspect the Mortgaged Property as often as deemed necessary by the Servicer in accordance with Accepted Servicing Practices to assure itself that the value of the Mortgaged Property is being preserved. In addition, if any Mortgage Loan is more than 45 days delinquent, the Servicer promptly shall inspect the Mortgaged Property and shall conduct subsequent inspections in accordance with Accepted Servicing Practices or as may be required by the primary mortgage guaranty insurer. Upon request, the Servicer shall produce an electronic report of each such inspection.

Section 3.15.

Restoration of Mortgaged Property.

The Servicer need not obtain the approval of the Master Servicer or the Trustee 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. For claims greater than $15,000, at a minimum, 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;

(iii)

the Servicer shall verify that the Mortgage Loan is not in default; and

(iv)

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

Section 3.16.

Maintenance of PMI and/or LPMI Policy; Claims.

(a)

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. The Servicer shall be obligated to make premium payments with respect to PMI Policies required to be maintained by the Mortgagor rather than the Seller, if the Mortgagor is required but fails to pay any PMI Policy premium, which shall be paid from the Servicer’s own funds. The Servicer shall not be required to make any premium payments with respect to LPMI Policies. Any premium payments made by the Servicer from its own funds pursuant to this Section 3.16(a) shall be recoverable by the Servicer as a Servicing Advance, subject to the reimbursement provisions of Section 3.04(iv).

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 loan-to-value of such Mortgage Loan is reduced to 78% or the PMI Policy is otherwise terminated pursuant to the Homeowners Protection Act of 1998, 12 USC §4901, et seq. 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.

(b)

With respect to each Mortgage Loan covered by a PMI Policy or LPMI Policy, the Servicer shall take all such actions on behalf of the Trustee as are necessary to service, maintain and administer the related Mortgage Loan in accordance with such Policy and to enforce the rights under such Policy. Except as expressly set forth herein, the Servicer shall have full authority on behalf of the Trust Fund to do anything it deems appropriate or desirable in connection with the servicing, maintenance and administration of such Policy; provided that the Servicer shall not take any action to permit any modification or assumption of a Mortgage Loan covered by an LPMI Policy or PMI Policy, or take any other action with respect to such Mortgage Loan, which would result in non-coverage under such Policy of any loss which, but for actions of any Servicer or the Subservicer, would have been covered thereunder. If the Qualified Insurer fails to pay a claim under an LPMI Policy or PMI Policy solely as a result of a breach by the Servicer or Subservicer of its obligations hereunder or under such 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 rights to reimbursement from the Trust Fund. The Servicer shall cooperate with the Qualified Insurers and shall furnish all reasonable evidence and information in the possession of the Servicer to which the Servicer has access with respect to the related Mortgage Loan; provided, however, notwithstanding anything to the contrary contained in any LPMI Policy or PMI Policy, the Servicer shall not be required to submit any reports to the related Qualified Insurer until a reporting date that is at least 15 days after the Servicer has received sufficient loan level information from the Seller to appropriately code its servicing systems in accordance with the Qualified Insurer’s requirements.

(c)

In connection with its activities as servicer, the Servicer agrees to prepare and present, on behalf of itself and the Trustee, claims to the Qualified 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 pursuant to Section 3.03(xiv), subject to withdrawal pursuant to Section 3.04.

(d)

Upon request by the Servicer, the Trustee shall furnish the Servicer with any powers of attorney and other documents (within three (3) Business Days upon request from the Servicer) in form as provided to it by the Servicer (and mutually acceptable to the Trustee and the Servicer) necessary or appropriate to enable the Servicer to service and administer any PMI or LPMI Policy; provided, however, that the Trustee shall not be liable for the actions of the Servicer under such power of attorney unless such actions of the Servicer are performed at, and in accordance with, the written direction of the Trustee.

(e)

The Servicer shall deposit into the Custodial Account pursuant to Section 3.03(v) hereof, all Insurance Proceeds received under the terms of a PMI Policy or a LPMI Policy.

(f)

Notwithstanding the provisions of (a) and (b) above, the Servicer shall not take any action in regard to any PMI Policy or LPMI Policy inconsistent with the interests of the Trustee or the Certificateholders or with the rights and interests of the Trustee or the Certificateholders under this Agreement.

Section 3.17.

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 in trust for the benefit of the Certificateholders, 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 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 Certificateholders.

If the Servicer hereafter becomes aware that a Mortgaged Property is an Environmental Problem Property, the Servicer will notify the Master Servicer and the NIMS Insurer of the existence of the Environmental Problem Property. Additionally, the Servicer shall set forth in such notice a description of such problem, a recommendation to the Master Servicer and the NIMS Insurer relating to the proposed action regarding the Environmental Problem Property, and the Servicer shall carry out the recommendation set forth in such notice unless otherwise directed by the Master Servicer or the NIMS Insurer in writing within five (5) days after its receipt (or deemed receipt) of such notice in accordance with the terms and provisions of Section 9.04 below. The Master Servicer shall be provided a copy of the NIMS Insurer’s instructions to the Servicer. Notwithstanding the foregoing, the Servicer shall obtain the Master Servicer’s and the NIMS Insurer’s written consent to any expenditures proposed to remediate Environmental Problem Properties or to defend any claims associated with Environmental Problem Properties if such expenses, in the aggregate, are expected to exceed $100,000. Failure to provide written notice of disapproval of the expenditure within five (5) days of receipt (or deemed receipt) of such request for prepaid expenditures shall be deemed an approval of such expenditure. The Master Servicer shall be provided with a copy of the NIMS Insurer’s instructions to the Servicer. If the Servicer has received reliable instructions to the effect that a Property is an Environmental Problem Property (e.g., Servicer obtains a broker’s price opinion which reveals the potential for such problem), the Servicer will not accept a deed-in-lieu of foreclosure upon any such Property without first obtaining a preliminary environmental investigation for the Property satisfactory to the Master Servicer or the NIMS Insurer.

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 (and provide a copy of the same to the NIMS Insurer and the Master Servicer) 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 (and provided a copy of the same to the NIMS Insurer and the Master Servicer), 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 three 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, as acceptable to the NIMS Insurer 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 and the NIMS Insurer with respect to the imposition of any such taxes.

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. Notwithstanding the previous sentence, prior to acceptance by the Servicer of an offer to sell any REO Property for a sale price that is less than 90% of the unpaid principal balance of the related Mortgage Loan, the Servicer shall notify the Master Servicer and the NIMS Insurer of such offering in writing which notification shall set forth all material terms of said offer (each a “Notice of Sale”). The Master Servicer and/or the NIMS Insurer shall be deemed to have approved the sale of any REO Property unless it notifies the Servicer in writing within five (5) 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 such sale. The proceeds of sale of the REO Property shall be promptly deposited in the Custodial Account.

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 proceeds of sale of the REO Property shall be promptly deposited in the Custodial Account. As soon as practical thereafter the expenses of such sale shall be paid and the Servicer shall reimburse itself for any related unreimbursed Servicing Advances, unpaid Xxxxx Fargo Servicing Fees and unreimbursed advances made pursuant to this Section or Section 4.03 and pay the Seller any unpaid Seller Remittance Amount to the extent not previously paid pursuant to Section 3.04.

The Servicer shall make advances of all funds necessary for the proper operation, management and maintenance of the REO Property, including the cost of maintaining any hazard insurance pursuant to Section 3.10, such advances to be reimbursed from the disposition or liquidation proceeds of the REO Property. 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 3.17 and of any reserves reasonably required from time to time to be maintained to satisfy anticipated liabilities for such expenses).

Section 3.18.

Real Estate Owned Reports.

Together with the statement furnished pursuant to Section 4.02, the Servicer shall furnish to the Master Servicer and the NIMS Insurer on or before the Remittance Date in 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 either the Master Servicer or the NIMS Insurer shall reasonably request.

Section 3.19.

Liquidation Reports.

Upon the foreclosure sale of any Mortgaged Property or the acquisition thereof by the Trustee pursuant to a deed in lieu of foreclosure, the Servicer shall submit to the Trustee and the Master Servicer a liquidation report with respect to such Mortgaged Property. In addition, the Servicer shall provide the Master Servicer a report setting forth Servicing Advances and other expenses incurred in connection with the liquidation of any Mortgage Loan.

Section 3.20.

Reports of Foreclosures and Abandonments of Mortgaged Property.

Following the foreclosure sale or abandonment of any Mortgaged Property, the Servicer shall report such foreclosure or abandonment as required pursuant to Section 6050J of the Code.

Section 3.21.

Prepayment Charges.

The Servicer or any designee of the Servicer shall not waive any Prepayment Charge with respect to any Mortgage Loan which contains a Prepayment Charge which prepays during the term of the charge, except as set forth herein. If the Servicer or its designee fails to collect the Prepayment Charge upon any prepayment of any Mortgage Loan which contains a Prepayment Charge pursuant to this Agreement, the Servicer shall pay the Trust Fund at such time (by deposit to the Custodial Account) an amount equal to the amount of the Prepayment Charge which was not collected. Notwithstanding the above, the Servicer or its designee may waive (and shall waive, in the case of (iii) below) a Prepayment Charge without paying the Trust Fund the amount of the Prepayment Charge if: (i) the Mortgage Loan is in default (defined as 61 days or more delinquent) and such waiver would maximize recovery of total proceeds, taking into account the value of such Prepayment Charge and the related Mortgage Loan; (ii) if the prepayment is not a result of a refinance by the Servicer or any of its affiliates and the Mortgage Loan is foreseen to be in default and such waiver would maximize recovery of total proceeds taking into account the value of such Prepayment Charge and the related Mortgage Loan; (iii) the collection of the Prepayment Charge would be in violation of applicable laws or (iv) notwithstanding any state or federal law to the contrary, any Prepayment Charge in any instance when a Mortgage Loan is accelerated or paid off in connection with the workout or foreclosure of a delinquent Mortgage Loan.

Section 3.22.

Confidentiality/Protecting Customer Information.

Each party agrees that it shall comply with all applicable laws and regulations regarding the privacy or security of Customer Information shall maintain appropriate administrative, technical and physical safeguards to protect the security, confidentiality and integrity of Customer Information, including, if applicable, maintaining security measures designed to meet the Interagency Guidelines Establishing Standards for Safeguarding Customer Information, 66 Fed. Reg. 8616 and complying with the privacy regulations under Title V of the Xxxxx-Xxxxx-Xxxxxx Act, 15 U.S.C. § 6801 et seq., and the rules promulgated thereunder. For purposes of this Section, “Customer Information” means any personal information concerning a Mortgagor that is disclosed by one party to this Agreement to the other.

Section 3.23.

Credit Reporting.

For each Mortgage Loan, the Servicer has and shall continue to accurately and fully furnish, in accordance with the Fair Credit Reporting Act and its implementing regulations, accurate and complete information (e.g., favorable and unfavorable) on its borrower credit files to each of the following credit repositories: Equifax Credit Information Services, Inc., Trans Union, LLC and Experian Information Solution, Inc., on a monthly basis. In addition, with respect to any Mortgage Loan serviced for a Xxxxxx Mae pool, the Servicer shall transmit full credit reporting data to each of such credit repositories in accordance with Xxxxxx Xxx Guide Announcement 95-19 (November 20, 1995), a copy of which is attached hereto as Exhibit G, reporting each of the following statuses, each month with respect to a Mortgage Loan in a Xxxxxx Mae pool: New origination, current, delinquent (30-60-90-days, etc) foreclosed or charged off.

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 three 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 second 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 Trustee or the Master Servicer.

Not later than the tenth (10th) calendar day of each month (or if such calendar day is not a Business Day, the immediately preceding Business Day), the Servicer shall furnish to the Master Servicer an electronic monthly remittance advice in the Fidelity (or any successor thereto) S50Y format (or in such other formats mutually agreed to between the Servicer and the Master Servicer), such advice relating to the period ending on the last day of the preceding calendar month and a monthly loan loss report in the format set forth in Exhibit E hereto; provided however, the information provided pursuant to Exhibit E shall be limited to that which is readily available to the Servicer and is mutually agreed to between the Servicer and the Master Servicer. The format of this monthly reporting may be amended from time to time to the extent necessary to comply with applicable law. In connection with prepayments in full, the Servicer will use its best efforts to deliver to the Master Servicer by the 15th calendar day of each month, but in no event later than the 17th day of each month, a monthly payoff remittance advice.

Such monthly remittance advice shall also be accompanied by a supplemental report provided to the Master Servicer which includes on an aggregate basis for the previous Due Period (i) the amount of claims filed on any LPMI Policy, (ii) the amount of any claim payments made on any LPMI Policy, (iii) the amount of claims denied or curtailed on any LPMI Policy and (iv) policies cancelled with respect to those Mortgage Loans covered by any LPMI Policy purchased by the Seller on behalf of the Trust Fund.

(b)

The Servicer shall prepare and file any and all usual and customary tax returns, information statements or other filings required to be delivered to any governmental taxing authority, the Securities Administrator or its designee pursuant to any applicable law with respect to the Mortgage Loans and the transactions contemplated hereby. In addition, the Servicer shall provide the Securities Administrator with such information concerning the Mortgage Loans as is necessary for such Securities Administrator to prepare federal income tax returns as the Securities Administrator may reasonably request from time to time. Such obligation of the Servicer shall be deemed satisfied to the extent that substantially comparable information has been provided by the Servicer throughout the calendar year.

(c)

If requested by the Master Servicer or the Depositor, the Servicer shall promptly notify the Master Servicer and the Depositor (i) of any legal proceedings pending against the Servicer of the type described in Item 1117 (§ 229.1117) of Regulation AB and (ii) if the Servicer shall become (but only to the extent not previously disclosed to the Master Servicer and the Depositor) at any time an affiliate of any of the parties listed on Exhibit I to this Agreement.

For the purpose of satisfying the reporting obligations under the Exchange Act with respect to the issuance of asset-backed securities, the Servicer shall provide to the Master Servicer and the Depositor prompt notice of the occurrence of any of the following: any event of default under the terms of this Agreement, any merger, consolidation or sale of substantially all of the assets of the Servicer, the Servicer’s engagement of any Subservicer, Subcontractor or vendor to perform or assist in the performance of any of the Servicer’s obligations under this Agreement, any material litigation involving the Servicer, and any affiliation or other significant relationship between the Servicer and other transaction parties.

(d)

Not later than the tenth calendar day of each month (or if such calendar day is not a Business Day, the immediately preceding Business Day), the Servicer shall provide to the Master Servicer and the Depositor notice of the occurrence of any material modifications, extensions or waivers of terms, fees, penalties or payments relating to the Mortgage Loans during the related Due Period.

Section 4.03.

Monthly Advances by Servicer.

On the Business Day immediately preceding each Remittance Date, the Servicer shall deposit in the Custodial Account from its own funds or from amounts held for future distribution, or both, an amount equal to all Monthly Payments (with interest adjusted to the Mortgage Loan Remittance Rate) which were due on the Mortgage Loans during the applicable Due Period and which were delinquent at the close of business on the immediately preceding Determination Date. In the case of Simple Interest Mortgage Loans the preceding sentence shall only apply to that portion of the Monthly Payment attributable to interest. Any amounts held for future distribution and so used shall be replaced by the Servicer by deposit in the Custodial Account on or before any future Remittance Date if funds in the Custodial Account on such Remittance Date shall be less than remittances to the Master Servicer required to be made on such Remittance Date. The Servicer shall keep appropriate records of such amounts and will provide such records to the Master Servicer and the NIMS Insurer upon reasonable request.

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 related Mortgage Loan.

Section 4.04.

Due Dates Other Than the First of the Month.

Mortgage Loans having Due Dates other than the first day of a month shall be accounted for as described in this Section 4.04. Any payment due on a day other than the first day of each month shall be considered due on the first day of the month following the month in which that payment is due as if such payment were due on the first day of said month. For example, a payment due on May 15 shall be considered to be due on June 1. Any payment collected on a Mortgage Loan after the Cut-off Date shall be deposited in the Custodial Account. For Mortgage Loans with Due Dates on the first day of a month, deposits to the Custodial Account begin with the payment due on the first of the month following the Cut-off Date.

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. When the Mortgaged Property has been conveyed by the Mortgagor, the Servicer shall, to the extent it has knowledge of such conveyance, 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 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, 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 seller of the Mortgaged Property pursuant to which the original Mortgagor is released from liability and the seller of the Mortgaged Property is substituted as Mortgagor and becomes liable under the Mortgage Note. If an assumption fee is collected by the Servicer for entering into an assumption agreement, such fee will 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.

To the extent that any Mortgage Loan is assumable, the Servicer shall inquire diligently into the creditworthiness of the proposed transferee, and shall use the underwriting criteria for approving the credit of the proposed transferee which are used by the Servicer, its affiliates or Xxxxxx Xxx with respect to underwriting mortgage loans of the same type as the Mortgage Loans. If the credit of the proposed transferee does not meet such underwriting criteria, the Servicer diligently shall, to the extent permitted by the Mortgage or the Mortgage Note and by applicable law, accelerate the maturity of the Mortgage Loan.

Section 5.02.

Satisfaction of Mortgages and Release of Mortgage Files.

Upon the payment in full of any Mortgage Loan, or the receipt by the Servicer of a notification that payment in full will be escrowed in a manner customary for such purposes, the Servicer shall notify the Master Servicer in the Monthly Remittance Advice as provided in Section 4.02, and may request the release of any Mortgage Loan Documents from the Seller in accordance with this Section 5.02 hereof.

If the Servicer satisfies or releases a Mortgage without first having obtained payment in full of the indebtedness secured by the Mortgage other than a modification or liquidation of the Mortgaged Property pursuant to the terms of this Agreement or should the Servicer otherwise prejudice any rights the Seller, the Trustee or the Trust Fund may have under the mortgage instruments, the Servicer shall deposit into the Custodial Account the entire outstanding principal balance, plus all accrued interest on such Mortgage Loan, on the day preceding the Remittance Date in the month following the date of such release. The Servicer shall maintain the Fidelity Bond and Errors and Omissions Insurance Policy as provided for in Section 3.13 insuring the Servicer against any loss it may sustain with respect to any Mortgage Loan not satisfied in accordance with the procedures set forth herein.

Section 5.03.

Servicing Compensation.

As consideration for servicing the Mortgage Loans subject to this Agreement, the Servicer shall retain the relevant Xxxxx Fargo Servicing Fee for each Mortgage Loan remaining subject to this Agreement during any month or part thereof. Such Xxxxx Fargo Servicing Fee shall be payable monthly. Additional servicing compensation in the form of Ancillary Income shall be retained by the Servicer and is not required to be deposited in the Custodial Account. The obligation of the Seller to pay the Xxxxx Fargo Servicing Fee is limited to, and the Xxxxx Fargo Servicing Fee is payable solely from, the interest portion (including recoveries with respect to interest from Liquidation Proceeds) of such Monthly Payment collected by the Servicer. The aggregate Xxxxx Fargo Servicing Fees for any month with respect to the Mortgage Loans shall be reduced by the aggregate Prepayment Interest Shortfall Amount for such month. The Servicer shall be obligated to pay the aggregate Prepayment Interest Shortfall Amount for any month to the extent not covered by the aggregate Xxxxx Fargo Servicing Fees for such month up to a maximum of the aggregate General Servicing Fees for such month. The Servicer shall be entitled to recover any unpaid Xxxxx Fargo Servicing Fee and the Seller shall be entitled to recover the Seller Remittance Amount, to the extent not remitted, out of Insurance Proceeds, Condemnation Proceeds, REO Disposition Proceeds or Liquidation Proceeds or other amounts on deposit in the Custodial Account, to the extent permitted in Section 3.04 and out of amounts derived from the operation and sale of an REO Property to the extent permitted by Section 3.17.

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.

Section 5.04.

Servicer Compliance Statement..

On or before March 1st of each calendar year, commencing in 2007, the Servicer shall deliver to the Master Servicer and the Depositor a Servicing Officer’s certificate in a mutually agreed upon format, addressed to the Master Servicer and the Depositor and signed by an authorized Servicing Officer, to the effect that (i) a review of the Servicer’s activities during the immediately preceding calendar year (or applicable portion thereof) and of its performance under this Agreement during such period has been made under such Servicing Officer’s supervision, and (ii) to the best of such Servicing Officer’s knowledge, based on such review, the Servicer has fulfilled all of its obligations under this Agreement in all material respects throughout such calendar year (or applicable portion thereof) or, if there has been a failure to fulfill any such obligation in any material respect, specifically identifying each such failure known to such officer and the nature and the status thereof.

Section 5.05.

The Servicer acknowledges that the parties identified in clause (a)(iv) above may rely on the certification provided by the Servicer pursuant to such clause in signing a Sarbanes Certification and filing such with the Commission. Neither the Master Servicer nor the Depositor will request delivery of a certification under clause (a)(iv) above unless a Depositor is required under the Exchange Act to file an annual report on Form 10-K with respect to the Trust Fund.

(b)

In the case of a Subservicer appointed subsequent to this Agreement, each assessment of compliance provided by such Subservicer pursuant to Section 5.05(a)(i) shall address all of the Servicing Criteria specified in Exhibit H hereto on or prior to the date of such appointment. An assessment of compliance provided by a Subcontractor pursuant to Section 5.05(a)(iii) need not address any elements of the Servicing Criteria other than those specified by the Servicer pursuant to Section 7.04.

Section 5.06.

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, the Securities Administrator, the NIMS Insurer (and each of their respective directors, officers, employees and agents) and the Trust Fund 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 Master Servicer, 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.

Neither the Master Servicer nor the Depositor shall exercise its right to request delivery of information or other performance under these provisions other than in good faith, or for purposes other than compliance with the Securities Act, the Exchange Act and the rules and regulations of the Commission thereunder (or the provision in a private offering of disclosure comparable to that required under the Securities Act). The Servicer acknowledges that interpretations of the requirements of Regulation AB may change over time, whether due to interpretive guidance provided by the Commission or its staff, consensus among participants in the asset-backed securities markets, advice of counsel, or otherwise, and agrees to comply with requests made by the Master Servicer or the Depositor in good faith for delivery of information under these provisions on the basis of evolving interpretations of Regulation AB. In connection with the transaction relating to this Agreement, the Servicer shall cooperate fully with the Master Servicer to deliver to the Master Servicer (including any of its assignees or designees) and the Depositor, any and all statements, reports, certifications, records and any other information necessary in the good faith determination of the Master Servicer or the Depositor to permit the Master Servicer or the Depositor to comply with the provisions of Regulation AB, together with such disclosures relating to the Servicer, any Subservicer and the Mortgage Loans, or the servicing of the Mortgage Loans, reasonably believed by the Master Servicer or the Depositor to be necessary in order to effect such compliance.

The Master Servicer (including any of its assignees or designees) shall cooperate with the Servicer by providing timely notice of requests for information under these provisions and by reasonably limiting such requests to information required, in the Master Servicer’s reasonable judgment, to comply with Regulation AB.

THE SERVICER

Section 7.01.

The Servicer shall keep in full effect its existence, rights and franchises as a national banking association, 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 Xxx- and Xxxxxxx Mac-approved servicer in good standing.

Section 7.02.

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 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.

This Agreement has been entered into 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, except as expressly provided in this Section 7.03 and Sections 3.20, 7.01 and 7.04, 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, the Master Servicer, the Trustee and the NIMS Insurer 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, the Master Servicer, Trustee and the NIMS Insurer 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 by any of them; provided that in each case, there must be delivered to the Seller, the Master Servicer, the Trustee and the NIMS Insurer 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 or the NIM Securities to be issued in the NIMS Transaction. Notwithstanding the foregoing, the Servicer, without the consent of the Seller, the Master Servicer, the Trustee or the NIMS Insurer, may retain a Subservicer or Subcontractor 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 Subservicers or Subcontractors 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, the Master Servicer, the Trustee and the NIMS Insurer 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 Seller, the Master Servicer, the Trustee and the NIMS Insurer, which Opinion of Counsel shall be in form and substance reasonably acceptable to each of them. 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 8.01.

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, except to the extent permitted by and in accordance with this Section 7.03 and Sections 7.01 and 7.04, without the prior written consent of the Seller, the Master Servicer, the Trustee and the NIMS Insurer, then such parties 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 shall not hire or otherwise utilize the services of any Subservicer to fulfill any of the obligations of the Servicer as servicer under this Agreement unless the Servicer complies with the provisions of paragraph (b) of this Section 7.04 and the proposed Subservicer (i) is an institution which is an approved Xxxxxx Xxx or Xxxxxxx Mac Seller/Servicer as indicated in writing and (ii) 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. The Servicer shall not hire or otherwise utilize the services of any Subcontractor, and shall not permit any Subservicer to hire or otherwise utilize the services of any Subcontractor, to fulfill any of the obligations of the Servicer as servicer under this Agreement unless the Servicer complies with the provisions of paragraph (c) of this Section 7.04.

(b)

It shall not be necessary for the Servicer to seek the consent of the Master Servicer and the Depositor to the utilization of any Subservicer. 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. 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. The Servicer shall cause any Subservicer used by the Servicer (or by any Subservicer) to comply with the provisions of this Section 7.04 and with Sections 4.02(c), 5.04, 5.05(a), 5.05(b) (and shall amend, with the consent of the parties hereto, Exhibit H to reflect such Subservicer’s assessment and attestation of compliance with the Servicing Criteria), 6.01(l) and 6.03 and Exhibit H of this Agreement to the same extent as if such Subservicer were the Servicer. The Servicer shall be responsible for obtaining from each Subservicer and delivering to the Master Servicer and the Depositor any servicer compliance statement required to be delivered by such Subservicer under Section 5.04, any reports on assessment of compliance and attestation required to be delivered by such Subservicer under Section 5.05 and any certification required to be delivered under 5.05 to the Person that will be responsible for signing the Sarbanes Certification under Section 5.05 as and when required to be delivered hereunder.

(c)

It shall not be necessary for the Servicer to seek the consent of the Master Servicer and the Depositor to the utilization of any Subcontractor. The Servicer shall promptly upon request provide the Master Servicer and the Depositor a written description (in form and substance satisfactory to the Master Servicer and the Depositor) of the role and function of each Subcontractor utilized by the Servicer or any Subservicer, specifying (A) the identity of each such Subcontractor, (B) which (if any) of such Subcontractors are Participating Entities, and (C) which elements of the servicing criteria set forth under Item 1122(d) of Regulation AB will be addressed in assessments of compliance provided by each Subcontractor identified pursuant to clause (B) of this paragraph.

As a condition to the utilization of any Subcontractor determined to be a Participating Entity, the Servicer shall cause any such Subcontractor used by the Servicer (or by any Subservicer) for the benefit of the Master Servicer and the Depositor to comply with the provisions of Sections 4.02(c), 5.04, 5.05, 6.01(l) and 6.03 and Exhibit H of this Agreement to the same extent as if such Subcontractor were the Servicer. The Servicer shall be responsible for obtaining from each Subcontractor and delivering to Master Servicer and the Depositor any assessment of compliance and attestation required to be delivered by such Subcontractor under Sections 5.04 and 5.05, in each case as and when required to be delivered.

ARTICLE VIII.

Any of the following occurrences shall constitute an event of default (each, an “Event of Default”) 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 (2) 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 the NIMS Insurer; or

(ii)

any failure by the Servicer to duly perform, within the required time period, its obligations to provide any certifications required pursuant to Sections 5.04 or 5.05 (including with respect to such certifications required to be provided by any Subservicer or Subcontractor pursuant to Section 7.04), except as provided below, which failure continues unremedied for a period of ten (10) days from the date of delivery required with respect to such certification; or

(iii)

except with respect to those items listed in clause (ii) above, any failure by the Servicer to duly perform, within the required time period, its obligations to provide any other information, data or materials required to be provided hereunder pursuant to Sections 4.02(c), 4.02(d), 6.01(l) and 7.04 (except as provided below), including any items required to be included in any Exchange Act report; or

(iv)

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 five (5) days after the date on which written notice of such failure, requiring the same to be remedied, shall have been given to the Servicer by the Master Servicer or the NIMS Insurer; or

(v)

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

(vi)

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, marshalling 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

(vii)

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

(viii)

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

(ix)

the Servicer ceases to meet the requirements of a Xxxxxx Xxx or Xxxxxxx Mac lender/servicer; or

(x)

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 in a manner not permitted under this Agreement; or

(xi)

if (x) any of the Rating Agencies reduces or withdraws the rating of any of the Certificates due to a reason attributable to the Servicer or (y) the Servicer’s residential primary servicer rating for servicing of subprime loans issued by any of the Rating Agencies is reduced to “below average” or withdrawn; or

(xii)

the net worth of the Servicer shall be less than $25,000,000.

In each and every such case, so long as an Event of Default shall not have been remedied, in addition to whatsoever rights the Master Servicer, the Trustee or the NIMS Insurer may have at law or equity to damages, including injunctive relief and specific performance, the Master Servicer, the Trustee or the NIMS Insurer, 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. The rights and obligations of the Servicer pursuant to subparagraphs (a)(ii) and (iii) above shall not be terminated if a failure of the Servicer to identify a Subcontractor as a Participating Entity was attributable solely to the role or functions of such Subcontractor with respect to mortgage loans other than the Mortgage Loans.

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 Trustee or the Master Servicer, as the case may be, with the consent of the other party and the NIMS Insurer. Upon written request from the Master Servicer, the Servicer shall prepare, execute and deliver to the successor entity designated by the Master Servicer 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, the Master Servicer, the NIMS Insurer, the Trustee 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 Trustee or the Master Servicer, with the consent of the other parties and the NIMS Insurer, 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, or (ii) mutual consent of the Servicer, the Seller and the Master Servicer in writing, provided such termination is also acceptable to the Rating Agencies and the NIMS Insurer or (iii) with respect to some or all of the Mortgage Loans, at the sole option of the Seller, without cause, upon 60 days’ written notice. Any such notice of termination shall be in writing and delivered to the Trustee, the Master Servicer, the NIMS Insurer and the Servicer by registered mail to the address set forth in Section 9.04 of this Agreement. The Servicer shall comply with the termination procedures set forth in Sections 8.01, 8.02 and 9.01 hereof.

In the event the Seller terminates the Servicer without cause with respect to some or all of the Mortgage Loans, the Seller shall be required to pay to the Servicer a Termination Fee in an amount equal to the product of (i) the Termination Fee Percentage and (ii) the outstanding principal balance of the terminated Mortgage Loans as of the date of such termination.

Section 8.03.

(Reserved.)

Section 8.04.

Termination for Distressed Mortgage Loans.

(a)

Subject to the requirements set forth in this Section 8.04, the Seller may terminate this Agreement with the prior consent of the Trustee, the NIMS Insurer and the Master Servicer, with respect to the servicing of those Mortgage Loans that are determined to be Distressed Mortgage Loans and in such event servicing of such Mortgage Loans shall be transferred to the Special Servicer. The appointment of a Special Servicer by the Seller and the execution of a special servicing agreement between the Seller and the Special Servicer shall be subject to the consent of the Trustee, the Master Servicer and the NIMS Insurer and the receipt of confirmation from the Rating Agencies that the transfer of servicing to the Special Servicer shall not result in a reduction of any rating previously given by such Rating Agency to any Certificate or the NIM Securities. Any monthly fee paid to the Special Servicer in connection with any Mortgage Loan serviced by such Special Servicer shall not exceed one-twelfth of the product of (a) 0.50% and (b) the outstanding principal balance of such Mortgage Loan. All unreimbursed Xxxxx Fargo Servicing Fees, Servicing Advances and Monthly Advances owing to the Servicer relating to such Distressed Mortgage Loans shall be reimbursed and paid to the Servicer by the successor Special Servicer upon such transfer to the Special Servicer. Any unpaid Seller Remittance Amount relating to such Distressed Mortgage Loans shall be paid to the Master Servicer by the successor Special Servicer for release to the Seller on the next succeeding Distribution Date.

(b)

All reasonable costs and expenses incurred in connection with a transfer of servicing to the Special Servicer including, without limitation, the costs and expenses of the Trustee or any other Person in connection with such transfer including the transfer of the Servicing Files and the other necessary data to the Special Servicer, shall be paid by the Seller from its own funds without reimbursement. The Seller shall be responsible for the delivery of all required transfer notices and will send a copy of the transfer notice to the Trustee.

(c)

Notwithstanding the foregoing provisions of this Section 8.04, the NIMS Insurer may, at its option, withhold their consent to the transfer of a Distressed Mortgage Loan to a Special Servicer and elect to purchase such Distressed Mortgage Loan at a price equal to its Purchase Price. Prior to such purchase, the Servicer shall be required to continue to make Monthly Advances with respect to such Distressed Mortgage Loan pursuant to Section 4.03. Any such purchase of a Distressed Mortgage Loan shall be accomplished by remittance to the Master Servicer for deposit in the Collection Account established pursuant to Section 4.01 of the Trust Agreement of the amount of the Purchase Price. The Servicer on behalf of the Trustee shall take reasonable steps to effectuate the transfer of servicing of such Distressed Mortgage Loan to the NIMS Insurer to the extent necessary, including the prompt delivery of all Servicing Files and other related documentation to the NIMS Insurer or its designee.

(d)

No Termination Fee shall be payable to the Servicer upon a termination pursuant to this Section 8.04.

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) within 90 days of the Servicer’s notice of such termination, 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) or Section 8.04, the Seller 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 the NIMS Insurer. Any approval of a successor servicer by the Master Servicer and the NIMS Insurer 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, the NIMS Insurer, the Seller 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 or the NIM Securities to be issued in the NIMS Transaction. 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, the Trustee, the NIMS Insurer and the Seller under Sections 6.02, 6.03 and 6.04, it being understood and agreed that the provisions of such Sections 6.01, 6.02, 6.03 and 6.04 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 90 days following notice of termination pursuant to Section 8.02(iii) or 30 days following notice of termination pursuant to Sections 8.01 or 8.02(ii), 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 of any Mortgage Notes and the related documents. 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, the NIMS Insurer and the Seller an instrument (i) accepting such appointment, wherein the successor shall make the representations and warranties set forth in Section 6.01 and provide for the same remedies set forth in Sections 6.02, 6.03 and 6.04 herein 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, 8.02 or 8.04 shall not affect any claims that the Seller, the Master Servicer, the NIMS Insurer 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 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, it shall notify the Trustee, the Seller and Master Servicer, the NIMS Insurer and the Depositor of such appointment in accordance with the procedures set forth in Section 9.04.

Section 9.02.

Costs.

The Seller 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 (i) the terminated or resigning servicer if such termination or resignation is a result of an occurrence of a termination event under Section 8.01, (ii) the related Seller if such termination is pursuant to Section 8.02(iii) and (iii) in all other cases by the Trust Fund. Subject to Section 2.02, the Seller, on behalf of the Depositor, shall pay the costs associated with the preparation, delivery and recording of Assignments of Mortgages by the Seller or the Seller’s designee.

Section 9.03.

Protection of Confidential Information.

The Servicer shall keep confidential and shall not divulge to any party, without the Seller’s prior written consent, any nonpublic information pertaining to the Mortgage Loans or any borrower thereunder, except to the extent that it is appropriate for the Servicer to do so in working with legal counsel, auditors, taxing authorities or other governmental agencies.

Section 9.05.

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 9.06.

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 related Mortgage Loan to refinance a Mortgage Loan, in whole or in part, without the prior written consent of the Trustee. Notwithstanding the foregoing, it is understood and agreed that promotions undertaken by the Servicer or any affiliate of the Servicer which are directed to the general public at large, including, without limitation, mass mailing based on commercially acquired mailing lists, newspaper, radio and television advertisements shall not constitute solicitation under this Section 9.06. Notwithstanding anything to the contrary, this Section 9.06 shall not prohibit the Servicer or its agents or affiliates from servicing the refinancing needs or other financial needs of a Mortgagor who without solicitation, contacts the Servicer or its agents or affiliates directly.

Section 9.07.

Section 9.10.

Section 9.11.

Section 9.12.

Assignment by the Seller.

The Seller shall assign (exclusive of the Seller’s rights arising under Section 8.02 or the Servicer’s rights under Sections 8.02(iii)), 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 of the Seller under this Agreement.

Section 9.13.

Subject

“Full-File” Reporting to Credit Repositories

Part IV, Section 107, of the servicing Guide currently requires servicers to report only 90-day delinquencies to the four major credit repositories. To ensure that the repositories have up-to-date information for both servicing and origination activity, we have decided to begin requiring—as of the month ending March 31, 1996—servicers to provide the credit repositories a “full-file” status report for the mortgages they service for us.

“Full-file” reporting requires that servicers submit a monthly report to each of the credit repositories to describe the exact status for each mortgage they service for us. The status reported generally should be the one in effect as of the last business day of each month. Servicers may, however, use a slightly later cut-off date—for example, at the and of the first week of a month—to assure that payment corrections, returned checks, and other adjustments related to the previous month’s activity can be appropriately reflected in their report for that month. Statuses that must be reported for any given mortgage include the following: new origination, current, delinquent (30-, 60-, 90-days, etc.), foreclosed, and charged-off. (The credit repositories will provide the applicable codes for reporting these statuses to them.) A listing of each of the major repositories to which “full-file” status reports must be sent is attached.

Servicers are responsible for the complete and accurate reporting of mortgage status information to the repositories and for resolving any disputes that arise about the information they report. Servicers must respond promptly to any inquiries from borrowers regarding specific mortgage status information about them that was reported to the credit repositories.

Servicers should contact their Customer Account Team in their lead Xxxxxx Xxx regional office if they have any questions about this expanded reporting requirement.
