ARTICLE II

CONVEYANCE OF MORTGAGE LOANS;

ORIGINAL ISSUANCE OF CERTIFICATES

SECTION 2.01.

Conveyance of the Mortgage Loans.

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

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

(i) the original Mortgage Note, endorsed in blank or in the following form: “Pay to the order of U.S. Bank National Association, as Trustee under the applicable agreement, without recourse,” with all prior and intervening endorsements showing a complete chain of endorsement from the originator to the Person so endorsing to the Trustee;

(ii) the original Mortgage, noting the presence of the MIN of the Mortgage Loan and language indicating that the Mortgage Loan is a MOM Loan if the Mortgage Loan is a MOM Loan, with evidence of recording thereon, and the original recorded power of attorney, if the Mortgage was executed pursuant to a power of attorney, with evidence of recording thereon;

(iii) unless the Mortgage Loan is registered on the MERS® System, an original Assignment in blank;

(iv) the original recorded Assignment or Assignments showing a complete chain of assignment from the originator to the Person assigning the Mortgage to the Trustee (or to MERS, if the Mortgage Loan is registered on the MERS® System and noting the presence of the MIN) as contemplated by the immediately preceding clause (iii);

(v) the original or copies of each assumption, modification, written assurance or substitution agreement, if any; and

(vi) the original lender’s title insurance policy, together with all endorsements or riders that were issued with or subsequent to the issuance of such policy, insuring the priority of the Mortgage as a first or second lien on the Mortgaged Property represented therein as a fee interest vested in the Mortgagor, or in the event such original title policy is unavailable, a written commitment or uniform binder or preliminary report of title issued by the title insurance or escrow company.

With respect to a maximum of approximately 1.0% of the Mortgage Loans, by outstanding Stated Principal Balance of the Mortgage Loans as of the Cut-off Date, if any original Mortgage Note referred to in Section 2.01(i) above cannot be located, the obligations of the Depositor to deliver such documents shall be deemed to be satisfied upon delivery to the Trustee (or the Custodian on behalf of the Trustee) of a photocopy of such Mortgage Note, if available, with a lost note affidavit substantially in the form of Exhibit I attached hereto. If any of the original Mortgage Notes for which a lost note affidavit was delivered to the Trustee (or the Custodian on behalf of the Trustee) is subsequently located, such original Mortgage Note shall be delivered to the Trustee (or the Custodian on behalf of the Trustee) within three Business Days.

Except with respect to any Mortgage Loan for which MERS is identified on the Mortgage or on a properly recorded assignment of the Mortgage as the mortgagee of record, the Trustee shall promptly (within sixty Business Days following the later of the Closing Date and the date of receipt by the Trustee or the Custodian of the recording information for a Mortgage, but in no event later than ninety days following the Closing Date) enforce the obligations of the Originator pursuant to the terms of the Mortgage Loan Purchase Agreement to submit or cause to be submitted for recording, at no expense to the Trust Fund, the Trustee, the Custodian, the Servicer or the Depositor, in the appropriate public office for real property records, each Assignment referred to in Sections 2.01(iii) and (iv) above and in connection therewith, the Trustee shall enforce the obligation of the Originator pursuant to the terms of the Mortgage Loan Purchase Agreement to execute each original Assignment in the following form: “U.S. Bank National Association, as Trustee under the applicable agreement.” In the event that any such Assignment is lost or returned unrecorded because of a defect therein, the Trustee shall enforce the obligation of the Originator pursuant to the Mortgage Loan Purchase Agreement to promptly prepare or cause to be prepared a substitute Assignment or cure or cause to be cured such defect, as the case may be, and thereafter cause each such Assignment to be duly recorded.

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

the term of this Agreement unless and until such Mortgage Loan is repurchased in accordance with the terms of this Agreement.

If any of the documents referred to in Sections 2.01(ii), (iii) or (iv) has, as of the Closing Date, been submitted for recording but either (x) has not been returned from the applicable public recording office or (y) has been lost or such public recording office has retained the original of such document, the obligations of the Depositor to deliver such documents shall be deemed to be satisfied upon (1) delivery to the Trustee (or the Custodian on behalf of the Trustee) of a copy of each such document certified by the Originator in the case of (x) above or the applicable public recording office in the case of (y) above to be a true and complete copy of the original that was submitted for recording and (2) if such copy is certified by the Originator, delivery to the Trustee (or the Custodian on behalf of the Trustee) promptly upon receipt thereof of either the original or a copy of such document certified by the applicable public recording office to be a true and complete copy of the original. Pursuant to the Mortgage Loan Purchase Agreement, notice shall be provided to the Trustee and the Rating Agencies by the Originator if delivery pursuant to clause (2) above will be made more than 180 days after the Closing Date.

If the original lender’s title insurance policy was not delivered pursuant to Section 2.01(vi) above, the Depositor shall deliver or cause to be delivered to the Trustee (or the Custodian on behalf of the Trustee), promptly after receipt thereof, the original lender’s title insurance policy with a copy thereof to the Servicer. The Depositor shall deliver or cause to be delivered to the Trustee (or the Custodian on behalf of the Trustee) promptly upon receipt thereof any other original documents constituting a part of a Mortgage File received with respect to any Mortgage Loan, including, but not limited to, any original documents evidencing an assumption or modification of any Mortgage Loan with a copy thereof to the Servicer.

The Depositor shall deliver or cause the Originator or the Trustee to deliver to the Servicer copies of all trailing documents required to be included in the servicing file at the same time the originals or certified copies thereof are delivered to the Trustee, such documents including but not limited to the mortgagee policy of title insurance and any mortgage loan documents upon return from the recording office. The Servicer shall not be responsible for any costs incurring in obtaining such documents and the Depositor shall cause the Servicer to be reimbursed for any such costs it may incur in connection with performing its obligations under this Agreement. Subject to Section 6.03(a), the Servicer shall have no liability as a result of an inability to service any Mortgage Loan due to its failure to receive any documents missing from the Mortgage File or servicing file.

All original documents relating to the Mortgage Loans that are not delivered to the Trustee (or the Custodian on behalf of the Trustee) are and shall be held by or on behalf of the Originator, the Seller, the Depositor or the Servicer, as the case may be, in trust for the benefit of the Trustee on behalf of the Certificateholders. In the event that any such original document is required pursuant to the terms of this Section 2.01 to be a part of a Mortgage File, such document shall be delivered promptly to the Trustee (or the Custodian on behalf of the Trustee). Any such original document delivered to or held by the Depositor that is not required pursuant to the terms of this Section to be a part of a Mortgage File, shall be delivered promptly to the Servicer.

The Depositor and the Trustee hereto understand and agree that it is not intended that any Mortgage Loan be included in the Trust that is a “High-Cost Home Loan” as defined by the Homeownership and Equity Protection Act of 1994 or any other applicable predatory or abusive lending laws.

The Depositor hereby directs the Trustee to, and the Trustee hereby agrees to execute, deliver and perform its obligations under each of the Cap Contracts on the Closing Date and thereafter on behalf of the Holders of the Group I Certificates, the Group II Certificates and the Mezzanine Certificates. The Depositor, the Servicer and the Holders of the Group I Certificates, the Group II Certificates and the Mezzanine Certificates, by their acceptance of such Certificates, acknowledge and agree that the Trustee shall execute, deliver and perform its obligations under each of the Cap Contracts and shall do so solely in its capacity as Trustee of the Trust Fund and not in its individual capacity.

SECTION 2.02.

Acceptance of REMIC I by Trustee.

The Trustee acknowledges receipt (or receipt by the Custodian as the duly appointed agent of the Trustee), subject to the provisions of Section 2.01 and subject to any exceptions noted on the exception report described in the next paragraph below, of the documents referred to in Section 2.01 (other than such documents described in Section 2.01(v)) above and all other assets included in the definition of “REMIC I” under clauses (i), (iii), (iv) and (v) (to the extent of amounts deposited into the Distribution Account) and declares that it holds and will hold such documents and the other documents delivered to it constituting a Mortgage File, and that it holds or will hold all such assets and such other assets included in the definition of “REMIC I” in trust for the exclusive use and benefit of all present and future Certificateholders.

The Trustee (or the Custodian on behalf of the Trustee) agrees to execute and deliver to the Depositor and the NIMS Insurer on or prior to the Closing Date an acknowledgment of receipt of the original Mortgage Note (with any exceptions noted), substantially in the form attached as Exhibit C-3 hereto.

The Trustee (or the Custodian on behalf of the Trustee) agrees, for the benefit of the Certificateholders and the NIMS Insurer, to review each Mortgage File and, within 45 days of the Closing Date, to certify in substantially the form attached hereto as Exhibit C-1 that, as to each Mortgage Loan listed in the Mortgage Loan Schedule (other than any Mortgage Loan paid in full or any Mortgage Loan specifically identified in the exception report annexed thereto as not being covered by such certification), (i) all documents constituting part of such Mortgage File (other than such documents described in Section 2.01(v)) required to be delivered to it pursuant to this Agreement are in its possession, (ii) such documents have been reviewed by it or the Custodian and appear regular on their face and relate to such Mortgage Loan and (iii) based on its or the Custodian’s examination and only as to the foregoing, the information set forth in the Mortgage Loan Schedule that corresponds to items (1), (3), (12), (15) and (18) of the definition of “Mortgage Loan Schedule” accurately reflects information set forth in the Mortgage File. It is herein acknowledged that, in conducting such review, the Trustee (or the Custodian on behalf of the Trustee) is under no duty or obligation (i) to inspect, review or examine any such documents, instruments, certificates or other papers to determine whether they are genuine,

enforceable, or appropriate for the represented purpose or whether they have actually been recorded or that they are other than what they purport to be on their face or (ii) to determine whether any Mortgage File should include any of the documents specified in clause (v) of Section 2.01.

Prior to the first anniversary date of this Agreement, the Trustee shall deliver (or cause the Custodian to deliver) to the Depositor, the NIMS Insurer and the Servicer a final certification in the form annexed hereto as Exhibit C-2 evidencing the completeness of the Mortgage Files, with any applicable exceptions noted thereon, and the Servicer shall forward a copy thereof to any Sub-Servicer.

If in the process of reviewing the Mortgage Files and making or preparing, as the case may be, the certifications referred to above, the Trustee (or the Custodian on behalf of the Trustee) finds any document or documents constituting a part of a Mortgage File to be missing or defective in any material respect, at the conclusion of its review the Trustee (or the Custodian on behalf of the Trustee) shall so notify the Depositor, the NIMS Insurer and the Servicer. In addition, upon the discovery by the Depositor, the NIMS Insurer, the Servicer or the Trustee of a breach of any of the representations and warranties made by the Originator or the Seller in the Mortgage Loan Purchase Agreement in respect of any Mortgage Loan which materially adversely affects such Mortgage Loan or the interests of the related Certificateholders in such Mortgage Loan, the party discovering such breach shall give prompt written notice to the other parties.

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

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

SECTION 2.03.

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

(a) Upon discovery or receipt of notice of any materially defective document in, or that a document is missing from, a Mortgage File or of the breach by the Originator or the Seller of any representation, warranty or covenant under the Mortgage Loan Purchase Agreement (including any representation, warranty or covenant regarding the Prepayment Charge Schedule) in respect of any Mortgage Loan that materially adversely affects the value of such Mortgage Loan or the interest therein of the Certificateholders, the Trustee shall promptly

notify the Originator, the NIMS Insurer, the Seller and the Servicer of such defect, missing document or breach and request that the Originator or the Seller, as applicable, deliver such missing document or cure such defect or breach within 90 days from the date the Originator or the Seller, as applicable, was notified of such missing document, defect or breach, and if the Originator or the Seller, as applicable, does not deliver such missing document or cure such defect or breach in all material respects during such period, the Trustee shall enforce the obligations of the Originator or the Seller, as applicable, under the Mortgage Loan Purchase Agreement to repurchase such Mortgage Loan from REMIC I at the Purchase Price within 90 days after the date on which the Originator or the Seller, as applicable, was notified (subject to Section 2.03(c)) of such missing document, defect or breach, if and to the extent that the Originator or the Seller, as applicable, is obligated to do so under the Mortgage Loan Purchase Agreement. The Purchase Price for the repurchased Mortgage Loan shall be remitted to the Servicer for deposit in the Collection Account and the Trustee (or the Custodian on behalf of the Trustee), upon receipt of written certification from the Servicer of such deposit, shall release to the Originator or the Seller, as applicable, the related Mortgage File and the Trustee (or the Custodian on behalf of the Trustee) shall execute and deliver such instruments of transfer or assignment, in each case without recourse, as the Originator or the Seller, as applicable, shall furnish to it and as shall be necessary to vest in the Originator or the Seller, as applicable, any Mortgage Loan released pursuant hereto. In furtherance of the foregoing, if the Originator or the Seller, as applicable, is not a member of MERS and repurchases a Mortgage Loan which is registered on the MERS® System, the Originator or the Seller, as applicable, at its own expense and without any right of reimbursement, shall cause MERS to execute and deliver an assignment of the Mortgage in recordable form to transfer the Mortgage from MERS to the Originator or the Seller, as applicable, and shall cause such Mortgage to be removed from registration on the MERS® System in accordance with MERS’ rules and regulations. Neither the Trustee nor the Custodian shall have any further responsibility with regard to such Mortgage File. In lieu of repurchasing any such Mortgage Loan as provided above, if so provided in the Mortgage Loan Purchase Agreement, the Originator or the Seller, as applicable, may cause such Mortgage Loan to be removed from REMIC I (in which case it shall become a Deleted Mortgage Loan) and substitute one or more Qualified Substitute Mortgage Loans in the manner and subject to the limitations set forth in Section 2.03(b); provided, however, the Originator or the Seller, as applicable, may not substitute a Qualified Substitute Mortgage Loan for any Deleted Mortgage Loan that violates any predatory or abusive lending law. It is understood and agreed that the obligation of the Originator or the Seller, as applicable, to cure or to repurchase (or to substitute for) any Mortgage Loan as to which a document is missing, a material defect in a constituent document exists or as to which such a breach has occurred and is continuing shall constitute the sole remedy respecting such omission, defect or breach available to the Trustee and the Certificateholders.

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

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

on behalf of the Trustee), for such Qualified Substitute Mortgage Loan or Loans, the Mortgage Note, the Mortgage, the Assignment in blank or to the Trustee, and such other documents and agreements, with all necessary endorsements thereon, as are required by Section 2.01, together with an Officers’ Certificate providing that each such Qualified Substitute Mortgage Loan satisfies the definition thereof and specifying the Substitution Adjustment Amount (as described below), if any, in connection with such substitution. The Trustee (or the Custodian on behalf of the Trustee) shall acknowledge receipt for such Qualified Substitute Mortgage Loan or Loans and, within ten Business Days thereafter, review such documents as specified in Section 2.02 and deliver to the Depositor, the NIMS Insurer and the Servicer, with respect to such Qualified Substitute Mortgage Loan or Loans, a certification substantially in the form attached hereto as Exhibit C-1, with any applicable exceptions noted thereon. Within one year of the date of substitution, the Trustee (or the Custodian on behalf of the Trustee) shall deliver to the Depositor, the NIMS Insurer and the Servicer a certification substantially in the form of Exhibit C-2 hereto with respect to such Qualified Substitute Mortgage Loan or Loans, with any applicable exceptions noted thereon. Monthly Payments due with respect to Qualified Substitute Mortgage Loans in the month of substitution are not part of REMIC I and will be retained by the Originator or the Seller, as applicable. For the month of substitution, distributions to Certificateholders will reflect the Monthly Payment due on such Deleted Mortgage Loan on or before the Due Date in the month of substitution, and the Originator or the Seller, as applicable, shall thereafter be entitled to retain all amounts subsequently received in respect of such Deleted Mortgage Loan. The Depositor shall give or cause to be given written notice to the Certificateholders and the NIMS Insurer that such substitution has taken place, shall amend the Mortgage Loan Schedule to reflect the removal of such Deleted Mortgage Loan from the terms of this Agreement and the substitution of the Qualified Substitute Mortgage Loan or Loans and shall deliver a copy of such amended Mortgage Loan Schedule to the Trustee, the Custodian, the Servicer and the NIMS Insurer. Upon such substitution, such Qualified Substitute Mortgage Loan or Loans shall constitute part of the Mortgage Pool and shall be subject in all respects to the terms of this Agreement and the Mortgage Loan Purchase Agreement, including, all applicable representations and warranties thereof included in the Mortgage Loan Purchase Agreement.

For any month in which the Originator or the Seller, as applicable, substitutes one or more Qualified Substitute Mortgage Loans for one or more Deleted Mortgage Loans, the Servicer will determine the amount (the “Substitution Adjustment Amount”), if any, by which the aggregate Purchase Price of all such Deleted Mortgage Loans exceeds the aggregate of, as to each such Qualified Substitute Mortgage Loan, the Stated Principal Balance thereof as of the date of substitution, together with one month’s interest on such Stated Principal Balance at the applicable Net Mortgage Rate, plus all outstanding Advances and Servicing Advances (including Nonrecoverable Advances and Nonrecoverable Servicing Advances) related thereto. On the date of such substitution, the Originator or the Seller, as applicable, will deliver or cause to be delivered to the Servicer for deposit in the Collection Account an amount equal to the Substitution Adjustment Amount, if any, and the Trustee (or the Custodian on behalf of the Trustee), upon receipt of the related Qualified Substitute Mortgage Loan or Loans and written notice by the Servicer of such deposit, shall release to the Originator or the Seller, as applicable, the related Mortgage File or Files and the Trustee (or the Custodian on behalf of the Trustee) shall execute and deliver such instruments of transfer or assignment, in each case without

recourse, the Originator or the Seller, as applicable, shall deliver to it and as shall be necessary to vest therein any Deleted Mortgage Loan released pursuant hereto.

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

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

the Holders of the Class P Certificates in any Prepayment Charge, the Servicer must pay the amount of such waived Prepayment Charge, for the benefit of the Holders of the Class P Certificates, by depositing such amount into the Collection Account. The foregoing shall not, however, limit any remedies available to the Certificateholders, the Depositor or the Trustee on behalf of the Certificateholders, pursuant to the Mortgage Loan Purchase Agreement respecting a breach of the representations, warranties and covenants of the Originator made in its capacity as a party to the Mortgage Loan Purchase Agreement.

ARTICLE III

ADMINISTRATION AND SERVICING

OF THE MORTGAGE LOANS

SECTION 3.01.

Servicer to Act as Servicer.

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

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

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

(iii)

the Servicer’s obligation to make Advances or Servicing Advances; or

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

To the extent consistent with the foregoing, the Servicer (a) shall seek to maximize the timely and complete recovery of principal and interest on the Mortgage Notes and (b) shall waive (or permit a Sub-Servicer to waive) a Prepayment Charge only under the following circumstances: (i) such waiver is standard and customary in servicing similar mortgage loans and such waiver relates to a default or a reasonably foreseeable default and would, in the reasonable judgment of the Servicer, maximize recovery of total proceeds taking into account the value of such Prepayment Charge and the related Mortgage Loan, (ii) the collection of such Prepayment Charge would be in violation of applicable laws, (iii) the amount of the Prepayment Charge set forth on the Prepayment Charge Schedule is not consistent with the related Mortgage Note or is otherwise unenforceable or (iv) the collection of such Prepayment Charge would be considered “predatory” pursuant to written guidance published or issued by any applicable federal, state or local regulatory authority acting in its official capacity and having jurisdiction over such matters. If a Prepayment Charge is waived as permitted by meeting the standard described in clauses (ii), (iii) or (iv) above, then the Trustee shall, enforce the obligation of the Originator to pay the amount of such waived Prepayment Charge to the Trustee for deposit in the Distribution Account for the benefit of the Holders of the Class P Certificates. Subject only to the above-described servicing standards and the terms of this Agreement and of the Mortgage Loans, the Servicer shall have full power and authority, acting alone or through Sub-Servicers as provided in Section 3.02, to do or cause to be done any and all things in connection with such servicing and administration which it may deem necessary or desirable. Without limiting the generality of the foregoing, the Servicer in its own name or in the name of a Sub-Servicer is

hereby authorized and empowered by the Trustee when the Servicer believes it appropriate in its best judgment in accordance with the servicing standards set forth above, to execute and deliver, on behalf of the Certificateholders and the Trustee, and upon notice to the Trustee, any and all instruments of satisfaction or cancellation, or of partial or full release or discharge, and all other comparable instruments, with respect to the Mortgage Loans and the Mortgaged Properties and to institute foreclosure proceedings or obtain a deed-in-lieu of foreclosure so as to convert the ownership of such properties, and to hold or cause to be held title to such properties, on behalf of the Trustee and Certificateholders. The Servicer shall service and administer the Mortgage Loans in accordance with applicable state and federal law and shall provide to the Mortgagors any reports required to be provided to them thereby. The Servicer shall also comply in the performance of this Agreement with all reasonable rules and requirements of each insurer under any standard hazard insurance policy. Subject to Section 3.17, within 15 days of the Closing Date, the Trustee shall execute, at the written request of the Servicer, and furnish to the Servicer and any Sub-Servicer any special or limited powers of attorney and other documents necessary or appropriate to enable the Servicer or any Sub-Servicer to carry out their servicing and administrative duties hereunder and the Trustee shall not be liable for the actions of the Servicer or any Sub-Servicers under such powers of attorney.

The Servicer further is authorized and empowered by the Trustee, on behalf of the Certificateholders and the Trustee, in its own name or in the name of the Sub-Servicer, when the Servicer or the Sub-Servicer, as the case may be, believes it is appropriate in its best judgment to register any Mortgage Loan on the MERS® System, or cause the removal from the registration of any Mortgage Loan on the MERS® System, to execute and deliver, on behalf of the Trustee and the Certificateholders or any of them, any and all instruments of assignment and other comparable instruments with respect to such assignment or re-recording of a Mortgage in the name of MERS, solely as nominee for the Trustee and its successors and assigns. Any reasonable expenses incurred in connection with the actions described in the preceding sentence or as a result of MERS discontinuing or becoming unable to continue operations in connection with the MERS® System, shall be reimbursable to the Servicer by withdrawal from the Collection Account pursuant to Section 3.11.

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

Notwithstanding anything in this Agreement to the contrary, the Servicer may not make any future advances with respect to a Mortgage Loan (except as provided in Section 4.03) and the Servicer shall not (i) permit any modification with respect to any Mortgage Loan that would change the Mortgage Rate, reduce or increase the Stated Principal Balance (except for reductions resulting from actual payments of principal) or change the final maturity date on such

Mortgage Loan (unless, as provided in Section 3.07, the Mortgagor is in default with respect to the Mortgage Loan or such default is, in the judgment of the Servicer, reasonably foreseeable) or (ii) permit any modification, waiver or amendment of any term of any Mortgage Loan that would both (A) effect an exchange or reissuance of such Mortgage Loan under Section 1001 of the Code (or Treasury regulations promulgated thereunder) and (B) cause any Trust REMIC to fail to qualify as a REMIC under the Code or the imposition of any tax on “prohibited transactions” or “contributions after the startup date” under the REMIC Provisions.

Notwithstanding anything in this Agreement to the contrary and notwithstanding its ability to do so pursuant to the terms of the related Mortgage Note, the Servicer shall not be required to enforce any provision in any Mortgage Note the enforcement of which would violate federal, state or local laws or ordinances designed to discourage predatory lending practices.

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

SECTION 3.02.

Sub-Servicing Agreements Between Servicer and Sub-Servicers.

(a) The Servicer may enter into Sub-Servicing Agreements with Sub-Servicers for the servicing and administration of the Mortgage Loans; provided, however, that (i) such sub-servicing arrangement and the terms of the related Sub-Servicing Agreement must provide for the servicing of the Mortgage Loans in a manner consistent with the servicing arrangement contemplated hereunder and (ii) the NIMS Insurer shall have consented to such Sub-Servicing Agreement. The Trustee is hereby authorized to acknowledge, at the request of the Servicer, any Sub-Servicing Agreement that meets the requirements applicable to Sub-Servicing Agreements set forth in this Agreement and that is otherwise permitted under this Agreement.

Each Sub-Servicer shall be (i) authorized to transact business in the state or states where the related Mortgaged Properties it is to service are situated, if and to the extent required by applicable law to enable the Sub-Servicer to perform its obligations hereunder and under the Sub-Servicing Agreement and (ii) a Freddie Mac or Fannie Mae approved mortgage servicer. Each Sub-Servicing Agreement must impose on the Sub-Servicer requirements conforming to the provisions set forth in Section 3.08 and provide for servicing of the Mortgage Loans consistent with the terms of this Agreement. The Servicer will examine each Sub-Servicing Agreement and will be familiar with the terms thereof. The terms of any Sub-Servicing Agreement will not be inconsistent with any of the provisions of this Agreement. The Servicer and the Sub-Servicers may enter into and make amendments to the Sub-Servicing Agreements or enter into different forms of Sub-Servicing Agreements; provided, however, that any such amendments or different forms shall be consistent with and not violate the provisions of this Agreement, and that no such amendment or different form shall be made or entered into which could be reasonably expected to be materially adverse to the interests of the Certificateholders without the consent of the Holders of Certificates entitled to at least 66% of the Voting Rights; provided, further, that the consent of the Holders of Certificates entitled to at least 66% of the Voting Rights shall not be required (i) to cure any ambiguity or defect in a Sub-Servicing

Agreement, (ii) to correct, modify or supplement any provisions of a Sub-Servicing Agreement, or (iii) to make any other provisions with respect to matters or questions arising under a Sub-Servicing Agreement, which, in each case, shall not be inconsistent with the provisions of this Agreement. Any variation without the consent of the Holders of Certificates entitled to at least 66% of the Voting Rights from the provisions set forth in Section 3.08 relating to insurance or priority requirements of Sub-Servicing Accounts, or credits and charges to the Sub-Servicing Accounts or the timing and amount of remittances by the Sub-Servicers to the Servicer, are conclusively deemed to be inconsistent with this Agreement and therefore prohibited. The Servicer shall deliver to the Trustee and the NIMS Insurer copies of all Sub-Servicing Agreements, and any amendments or modifications thereof, promptly upon the Servicer’s execution and delivery of such instruments.

(b) As part of its servicing activities hereunder, the Servicer, for the benefit of the Trustee and the Certificateholders, shall enforce the obligations of each Sub-Servicer under the related Sub-Servicing Agreement, including, without limitation, any obligation of a Sub-Servicer to make advances in respect of delinquent payments as required by a Sub-Servicing Agreement. Such enforcement, including, without limitation, the legal prosecution of claims, termination of Sub-Servicing Agreements, and the pursuit of other appropriate remedies, shall be in such form and carried out to such an extent and at such time as the Servicer, in its good faith business judgment, would require were it the owner of the related Mortgage Loans. The Servicer shall pay the costs of such enforcement at its own expense, and shall be reimbursed therefor only (i) from a general recovery resulting from such enforcement, to the extent, if any, that such recovery exceeds all amounts due in respect of the related Mortgage Loans, or (ii) from a specific recovery of costs, expenses or attorneys’ fees against the party against whom such enforcement is directed.

SECTION 3.03.

Successor Sub-Servicers.

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

Any Sub-Servicing Agreement shall include the provision that such agreement may be immediately terminated by the Trustee (if the Trustee is acting as Servicer) without fee, in accordance with the terms of this Agreement, in the event that the Servicer (or the Trustee, if it is then acting as Servicer) shall, for any reason, no longer be the Servicer (including termination due to a Servicer Event of Default).

SECTION 3.04.

Liability of the Servicer.
