It is, further, not the intention of the parties that such conveyance be deemed the grant of a security interest in the Mortgage Pool Assets by the Company to the Trust to secure a debt or other obligation of the Company.

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

Section 2.05. Delivery of Mortgage Files.

On the Closing Date, the Company shall deliver to and deposit with, or cause to be delivered to and deposited with, the Trustee or the Initial Custodian the Mortgage Files, which shall at all times be identified in the records of the Trustee or the Initial Custodian, as applicable, as being held by or on behalf of the Trust.

Concurrently with the execution and delivery hereof, the Company shall cause to be filed with respect to each Cooperative Loan the UCC assignment or amendment referred to in clause (Y)(vii) of the definition of “Mortgage File.” In connection with its servicing of Cooperative Loans, the Servicer shall use its best efforts to file timely continuation statements, if necessary, with regard to each financing statement relating to a Cooperative Loan.

The Trustee is authorized, with the Servicer’s consent, to appoint on behalf of the Trust any bank or trust company approved by each of the Company and the Servicer as Custodian of the documents or instruments referred to in this Section 2.05 or in Section 2.12, and to enter into a Custodial Agreement for such purpose; provided, however, that the Trustee shall be and remain liable for the acts and omissions of any such Custodian to the extent (and only to the extent) that it would have been liable for such acts and omissions hereunder had such acts and omissions been its own acts and omissions. Any documents delivered by the Company or the Servicer to the Custodian, if any, shall be deemed to have been delivered to the Trustee for all purposes hereunder; and any documents held by the Custodian, if any, shall be deemed to be held by the Trustee for all purposes hereunder. There shall be a written Custodial Agreement between the Trustee and each Custodian. Each Custodial Agreement shall contain an acknowledgment by the Custodian that all Mortgage Pool Assets, Mortgage Files, and other documents and property held by it at any time are held by it for the benefit of the Trust. Pursuant to the Initial Custodial Agreement, the Initial Custodian shall perform responsibilities of the Trustee on the Trustee’s behalf with respect to the delivery, receipt, examination, custody and release of the Mortgage Files related to the Mortgage Loans identified in the Initial Custodial Agreement, as provided therein. The Trustee shall not have any responsibility for the acts or omissions of the Initial Custodian; provided, however, that nothing herein shall relieve the Trustee from liability for its own negligent action, its own negligent failure to act or its willful misconduct.

On or promptly after the Closing Date, the Servicer shall cause the MERS® System to indicate that each MERS Loan, if any, has been assigned to the Trustee, without recourse, or to the Trust, without recourse, by including in the MERS® System computer files (a) the code necessary to identify the Trustee and (b) the code necessary to identify the series of the Certificates issued in connection with such Mortgage Loans; provided, however, that in the event the Company acquired such Mortgage Loans from an affiliate of the Company, then the Servicer need not cause the MERS® System to indicate such assignment. The Servicer shall not alter the codes referenced in this paragraph with respect to any MERS Loan during the term of this Agreement except in connection with an assignment of such MERS Loan or de-registration thereof from the MERS® System in accordance with the terms of this Agreement.

The Servicer shall, on behalf of REMIC I, elect to treat REMIC I as a REMIC within the meaning of Section 860D of the Code and, if necessary, under applicable state laws. Such election shall be included in the Form 1066 and any appropriate state return to be filed on behalf of REMIC I for its first taxable year.

The Closing Date is hereby designated as the “startup day” of REMIC I within the meaning of Section 860G(a)(9) of the Code.

The regular interests (as set forth in the table contained in the Preliminary Statement hereto) relating to REMIC I are hereby designated as “regular interests” in REMIC I for purposes of Section 860G(a)(1) of the Code. The Class R-1 Residual Interest is hereby designated as the sole class of “residual interest” in REMIC I for purposes of Section 860G(a)(2) of the Code.

The parties intend that the affairs of REMIC I shall constitute, and that the affairs of REMIC I shall be conducted so as to qualify REMIC I as a REMIC. In furtherance of such intention, the Servicer shall, on behalf of REMIC I: (a) prepare and file, or cause to be prepared and filed, a federal tax return using a calendar year as the taxable year and using an accrual method of accounting for REMIC I when and as required by the REMIC Provisions and other applicable federal income tax laws; (b) make an election, on behalf of the trust, for REMIC I to be treated as a REMIC on the federal tax return of REMIC I for its first taxable year, in accordance with the REMIC Provisions; (c) prepare and forward, or cause to be prepared and forwarded, to the Holders of the REMIC I Regular Interests and the Class R-1 Residual Interest and the Trustee, all information reports as and when required to be provided to them in accordance with the REMIC Provisions, and make available the information necessary for the application of Section 860E(e) of the Code; (d) conduct the affairs of REMIC I at all times that any REMIC I Regular Interests are outstanding so as to maintain the status of REMIC I as a REMIC under the REMIC Provisions; (e) not knowingly or intentionally take any action or omit to take any action that would cause the termination of the REMIC status of REMIC I; and (f) pay the amount of any federal prohibited transaction penalty taxes imposed on REMIC I when and as the same shall be due and payable (but such obligation shall not prevent the Servicer from contesting any such tax in appropriate proceedings and shall not prevent the Servicer from withholding payment of such tax, if permitted by law, pending the outcome of such proceedings).

The Company and the Trustee shall promptly provide the Servicer with such information in the possession of the Company or the Trustee, respectively, as the Servicer may from time to time request for the purpose of enabling the Servicer to prepare or cause the preparation of tax returns. If so requested by the Servicer, the Trustee shall sign tax returns on behalf of the REMICs.

In the event that a Mortgage Loan is discovered to have a defect which, had such defect been discovered before the startup day, would have prevented such Mortgage Loan from being a “qualified mortgage” within the meaning of Section 860G(a)(3) of the Code, and the Company does not repurchase such Mortgage Loan within 90 days of such date, the Servicer, on behalf of the Trust, shall within 90 days of the date such defect is discovered sell such Mortgage Loan at such price as the Servicer, in its sole discretion, determines to be the greatest price that will result in the purchase thereof within 90 days of such date, unless the Servicer delivers to the Trustee an Opinion of Counsel to the effect that continuing to hold such Mortgage Loan will not adversely affect the status of the electing portion of REMIC I as a REMIC for federal income tax purposes.

In the event that the Servicer has paid any federal prohibited transaction penalty taxes imposed on REMIC I pursuant to clause (f) of the third preceding paragraph, the Trustee on behalf of the Trust shall (unless the Servicer’s failure to exercise reasonable care was the primary cause of the imposition of such taxes) reimburse the Servicer or its agent, upon the written request of the Servicer, for such payment from amounts on deposit in the Certificate Account in reduction of the REMIC I Available Distribution Amount for the applicable Distribution Date. In the event that any federal prohibited transaction penalty taxes are imposed on REMIC I and not paid by the Servicer pursuant to clause (f) of the third preceding paragraph, the Trustee on behalf of the Trust shall pay such taxes from amounts on deposit in the Certificate Account in reduction of the REMIC I Available Distribution Amount for the applicable Distribution Date. The amount so reimbursed or paid pursuant to either of the immediately preceding two sentences shall be allocated as a loss to the Class R-1 Residual Interest, in reduction of the Class Principal Balance thereof.

Neither the Trustee nor the Tax Matters Person shall knowingly or intentionally take any action that would cause the termination of the REMIC status of REMIC I.

Section 2.07. Acceptance by Trustee. The Trustee acknowledges receipt (or with respect to any Mortgage Loan subject to a Custodial Agreement, including the Initial Custodial Agreement, receipt by the Custodian thereunder) on behalf of the Trust of the documents (or certified copies thereof as specified in Section 2.05) referred to in Section 2.05 above, but without having made the review required to be made within 45 days pursuant to this Section 2.07. The Trustee acknowledges that all Mortgage Pool Assets, Mortgage Files and related documents and property held by it at any time are held by it as Trustee of the Trust for the benefit of the holders of the REMIC I Regular Interests, the Class PPP Certificates and the Class R-1 Residual Interest. The Trustee shall review (or, with respect to the Mortgage Loans identified in the Initial Custodial Agreement, cause the Initial Custodian to review) each Mortgage File within 45 days after the Closing Date and deliver to the Company a certification (or, with respect to the Mortgage Loans identified in the Initial Custodial Agreement, cause the Initial Custodian to deliver to the Company a certification, which satisfies the applicable requirements of this Agreement; provided, however, that with respect to the Initial Custodian, Exhibit B-2 to the Initial Custodial Agreement is deemed to satisfy the applicable requirements of this Agreement) in the form attached as Exhibit M hereto, to the effect that, except as noted, all documents required (in the case of instruments described in clauses (X)(ii), (X)(iv) and (Y)(ix) of the definition of “Mortgage File,” known by the Trustee to be required) pursuant to the definition of “Mortgage File” and Section 2.05 have been executed and received, and that such documents relate to the Mortgage Loans identified in the Mortgage Loan Schedule. In performing such review, the Trustee may rely upon the purported genuineness and due execution of any such document, and on the purported genuineness of any signature thereon. The Trustee shall not be required to make any independent examination of any documents contained in each Mortgage File beyond the review specifically required herein. The Trustee makes no representations as to: (i) the validity, legality, enforceability or genuineness of any of the Mortgage Loans identified on the Mortgage Loan Schedule, or (ii) the collectability, insurability, effectiveness or suitability of any Mortgage Loan.

If the Trustee finds any document or documents required to be included in the Mortgage File for a Mortgage Loan pursuant to the definition of “Mortgage File” not to have been executed and received, the Trustee shall promptly so notify the Servicer. Upon notice from the Trustee or the Custodian that any document required to be included in the Mortgage File for a Mortgage Loan has not been executed and received, the Servicer shall promptly notify the Seller of such defect and take appropriate steps on behalf of the Trust to enforce the Seller’s obligation, pursuant to Section 2.4 of the Mortgage Loan Purchase Agreement, to correct or cure such defect or repurchase or substitute for such Mortgage Loan, in accordance with and subject to the time limitations set forth in such Section 2.4; provided, however, that the Servicer shall not require or permit the Seller to repurchase a Mortgage Loan pursuant to such Section 2.4 of the Mortgage Loan Purchase Agreement more than two years after the Closing Date unless (a) such defect would cause the Mortgage Loan to be other than a “qualified mortgage” (as defined in the Code), (b) such Mortgage Loan is in default, or default is in the judgment of the Servicer reasonably imminent, or (c) the Servicer, at the expense of the Seller, delivers to the Trustee an Opinion of Counsel addressed to the Trust and the Trustee to the effect that the repurchase of such Mortgage Loan will not give rise to a tax on a prohibited transaction, as defined in Section 860F(a) of the Code; provided, further, that in the event that such defect consists solely of the failure of the Seller to deliver any Recording Document with respect to such Mortgage Loan, due to a delay on the part of the recording office, then the Servicer shall instead notify the Seller of such defect and take appropriate steps on behalf of the Trust to enforce the Seller’s obligation, pursuant to Section 2.3 of the Mortgage Loan Purchase Agreement, to comply with the procedure described in such Section 2.3.

In connection with the enforcement of the Seller’s repurchase or substitution obligation pursuant to Section 2.4 of the Mortgage Loan Purchase Agreement, the Servicer and the Trustee shall comply with the additional provisions set forth in Section 2.10 hereof.

Section 2.08. Representation and Warranty of the Company Concerning the Mortgage Loans. The Company hereby represents and warrants to the Trust that, immediately upon the transfer and assignment contemplated by Section 2.04, the Trust shall have good title to, and will be the sole legal owner of, each Mortgage Loan, free and clear of any encumbrance or lien, other than (i) any lien arising before the Company’s purchase of the Mortgage Loan from the Seller and (ii) any lien arising under this Agreement.

The representation and warranty set forth in this Section 2.08 shall survive delivery of the respective Mortgage Files to the Trustee or the Custodian, as the case may be, and shall continue throughout the term of this Agreement. Upon discovery by any of the Company, the Servicer or the Trustee of a breach of the foregoing representation and warranty which materially and adversely affects the value of the related Mortgage Loans or the interests of the Trust in the related Mortgage Loans, the party discovering such breach shall give prompt written notice to the others. Within 90 days of its discovery or its receipt of notice of breach, the Company shall repurchase or substitute for the affected Mortgage Loan or Mortgage Loans or any property acquired in respect thereof by the Trust, unless it has cured such breach in all material respects. Any such substitution shall be made within the three-month period commencing on the Closing Date (or within the two-year period commencing on the Closing Date if the related Mortgage Loan is a “defective obligation” within the meaning of Section 860G(a)(4)(B)(ii) of the Code and Treasury Regulation Section 1.860G-2(f)). Any such repurchase shall be made at the Repurchase Price; provided, however, that no Mortgage Loan shall be repurchased pursuant to this Section 2.08 unless (a) the Mortgage Loan to be repurchased is in default, or default is in the judgment of the Servicer reasonably imminent, or (b) the Servicer, at the expense of the Company, delivers to the Trustee an Opinion of Counsel addressed to the Trust and the Trustee to the effect that the repurchase of such Mortgage Loan will not give rise to a tax on a prohibited transaction, as defined in Section 860F(a) of the Code. If such breach would cause the Mortgage Loan to be other than a “qualified mortgage” (as defined in the Code), then notwithstanding the previous sentence, the repurchase or substitution must occur within the sooner of (i) 90 days from the date the defect was discovered or (ii) in the case of substitution, two years from the Closing Date.

Any number of Substitute Mortgage Loans may be substituted for any number of Reacquired Mortgage Loans, subject to the limitations described in the next sentence. With respect to the Mortgage Loans substituted on any date, (i) the aggregate Principal Balance of the Substitute Mortgage Loans shall not exceed the aggregate Principal Balance of the Reacquired Mortgage Loans, (ii) each Substitute Mortgage Loan shall mature no later than, and not more than two years before, the weighted average date of maturity of the Reacquired Mortgage Loans, (iii) each Substitute Mortgage Loan shall have a Current Loan-to-Value Ratio equal to or less than the weighted average Current Loan-to-Value Ratio of the Reacquired Mortgage Loans and (iv) each Substitute Mortgage Loan shall have a Mortgage Interest Rate on the date of substitution equal to or no more than 1 percentage point greater than the weighted average Mortgage Interest Rate of the Reacquired Mortgage Loans and (v) if the Reacquired Mortgage Loans do not provide for any payments of principal during an initial period, each Substitute Mortgage Loan also shall not provide for payments of principal during such initial period. In addition, a Substitute Mortgage Loan shall not be a High Cost Loan or Covered Loan (as such terms are defined in the Standard & Poor's LEVELS® Glossary in effect on the date of substitution, with such exceptions thereto as the Company and S&P may reasonably agree). A Substitute Mortgage Loan may be substituted for a defective Mortgage Loan that is itself a Substitute Mortgage Loan.

In connection with the substitution of one or more Substitute Mortgage Loans for one or more Reacquired Mortgage Loans on any date, the Company shall pay to the Trust the Substitution Price for such Reacquired Mortgage Loans, and such payment by the Company shall be treated in the same manner as proceeds of the repurchase by the Company of a Mortgage Loan pursuant to this Section 2.08.

With respect to each Substitute Mortgage Loan, the Company shall (a) deliver to and deposit with, or cause to be delivered to and deposited with, the Trustee or the Custodian on behalf of the Trust the Mortgage File for such Substitute Mortgage Loan and (b) cause the Seller to enter into an agreement with the Trust and the Servicer pursuant to which, with respect to such Substitute Mortgage Loan, the Seller will (i) make, as of the date of substitution, each of the representations and warranties that the Seller made pursuant to Section 3.1 of the Mortgage Loan Purchase Agreement with respect to the original Mortgage Loan (except that references to “Closing Date” or “Cut-off Date” in such Section 3.1 shall be changed to the applicable date of substitution), (ii) agree to deliver any missing Recording Documents with respect to such Substitute Mortgage Loan, and to repurchase or substitute for such Substitute Mortgage Loan in the event of the Seller’s failure to deliver any document required to be included in such Mortgage File or in the event of the Seller’s material breach of any of such representations and warranties, upon the same terms as the Seller’s corresponding obligations with respect to the original Mortgage Loan pursuant to Sections 2.3, 2.4 and 3.3 of the Mortgage Loan Purchase Agreement, and (iii) convey such Substitute Mortgage Loan to the Trust.

The Company shall pay all costs and expenses incurred in connection with any repurchase or substitution by the Company made pursuant to this Section 2.08.

With respect to each Mortgage Loan repurchased pursuant to this Section 2.08 and each Reacquired Mortgage Loan, the Company shall own and be entitled to receive all scheduled payments due after the date of repurchase or substitution, as applicable, any Curtailments received in or after the calendar month of repurchase or substitution, as applicable, and any Payoffs received after the 14th day of the calendar month of repurchase or substitution, as applicable; and with respect to each Substitute Mortgage Loan, the Company shall own and be entitled to receive all payments due under the related Mortgage Note on or before the date of substitution. Any such payments received by the Servicer shall promptly be remitted by the Servicer to the Company. With respect to each Substitute Mortgage Loan, the Trust shall own and be entitled to receive all scheduled payments due after the date of substitution, any Curtailments received in or after the calendar month of substitution, and any Payoffs received after the 14th day of the calendar month of substitution. Any such payments received by the Company shall promptly be remitted by the Company to the Servicer.

In connection with any repurchase or substitution by the Company made pursuant to this Section 2.08, the Servicer and the Trustee (to the extent of any obligations on its part) shall comply with the additional provisions set forth in Section 2.10 hereof.

Section 2.09. Representations and Warranties of the Seller Concerning the Mortgage Loans. The Company hereby assigns to the Trust all of its rights under the Mortgage Loan Purchase Agreement, to the extent that the Mortgage Loan Purchase Agreement relates to the Mortgage Loans.

Upon discovery by any of the Company, the Servicer or the Trustee (in the case of the Trustee, having actual knowledge thereof) of a breach of any of the representations and warranties in respect of the Mortgage Loan set forth in Section 3.1 of the Mortgage Loan Purchase Agreement (in the case of a breach of the representation set forth in clause (xxix) of such Section 3.1 thereof, determined as specified in Section 3.3(b) thereof) that materially and adversely affects the value of the related Mortgage Loans or the interests of the Trust in the related Mortgage Loans, the party discovering such breach shall give prompt written notice to the others. Any breach of the representation set forth in clause (xxvii) or clause (xxviii) of such Section 3.1 thereof shall be deemed to materially and adversely affect the value of the related Mortgage Loans or the interests of the Trust in the related Mortgage Loans. The Servicer shall promptly notify the Seller of such breach and take appropriate steps on behalf of the Trust to enforce the Seller’s obligation, pursuant to Section 3.3 of the Mortgage Loan Purchase Agreement, to cure such breach in all material respects or repurchase or substitute for the affected Mortgage Loan or Mortgage Loans or any property acquired in respect thereof, in accordance with and subject to the time limitations set forth in such Section 3.3; provided, however, that the Seller shall not be required or permitted to repurchase a Mortgage Loan pursuant to such Section 3.3 thereof unless (a) such defect would cause the Mortgage Loan to be other than a “qualified mortgage” (as defined in the Code), (b) such Mortgage Loan is in default, or default is in the judgment of the Servicer reasonably imminent, or (c) the Servicer, at the expense of the Seller, delivers to the Trustee an Opinion of Counsel addressed to the Trust and the Trustee to the effect that the purchase of such Mortgage Loan will not give rise to a tax on a prohibited transaction, as defined in Section 860F(a) of the Code.

In connection with the enforcement of the Seller’s repurchase or substitution obligation pursuant to Section 3.3 of the Mortgage Loan Purchase Agreement, the Servicer and the Trustee shall comply with the additional provisions set forth in Section 2.10 hereof.

Section 2.10. Additional Provisions Relating to Repurchases of and Substitutions for Mortgage Loans by the Company or the Seller.

The Servicer shall deposit or cause to be deposited in the Custodial Account for P&I (i) the Repurchase Price that it receives for each Mortgage Loan repurchased by the Company pursuant to Section 2.08 hereof, (ii) the Substitution Price that it receives in connection with each substitution for a Mortgage Loan by the Company pursuant to such Section 2.08, (iii) the Repurchase Price (as defined in the Mortgage Loan Purchase Agreement) that it receives for each Mortgage Loan repurchased by the Seller pursuant to Section 2.4 or 3.3 of the Mortgage Loan Purchase Agreement and (iv) the Substitution Price (as defined in the Mortgage Loan Purchase Agreement) that it receives in connection with each substitution for a Mortgage Loan by the Seller pursuant to such Section 2.4 or 3.3 thereof.

Upon receipt by the Trustee of written notification, signed by a Servicing Officer, of the deposit in the Custodial Account for P&I of the Repurchase Price or Substitution Price, as applicable, and (in the case of a substitution for a Mortgage Loan) upon receipt by the Trustee of such instruments of transfer or assignment, in each case without recourse, as shall be necessary to vest in the Trust title to any Substitute Mortgage Loan, the Trustee shall (or, if applicable, shall cause the Custodian in accordance with the Custodial Agreement to) on behalf of the Trust release to the Company or the Seller, as applicable, or to such person’s designee, the Mortgage File for such Mortgage Loan and shall execute and deliver (or, in the event that the Mortgage Files are held in the name of the Custodian, shall cause the Custodian in accordance with the Custodial Agreement to execute and deliver) on behalf of the Trust such instruments of transfer or assignment, in each case without recourse, as shall be necessary to vest in such person or its designee or assignee title to any such Mortgage Loan. In furtherance of the foregoing, if such Mortgage Loan is a MERS Loan and as a result of the repurchase thereof or substitution therefor such Mortgage Loan shall cease to be serviced by a servicer that is a member of MERS or if the Company or the Seller, as applicable, or such person’s assignee, shall so request, the Servicer shall cause MERS to execute and deliver an assignment of the Mortgage in recordable form from MERS to such person or its assignee and shall cause the Mortgage Loan to be removed from registration on the MERS® System in accordance with MERS’ rules and procedures.

It is understood and agreed that the obligation of (a) the Seller, pursuant to Section 2.4 of the Mortgage Loan Purchase Agreement, to repurchase or substitute for any Mortgage Loan as to which a defect in a constituent document exists, or (b) of the Seller or the Company, as applicable, pursuant to Section 3.3 of the Mortgage Loan Purchase Agreement or Section 2.8 hereof, to repurchase or substitute for any Mortgage Loan as to which a breach has occurred and is continuing, shall constitute the sole remedy respecting such defect or breach available to the Trust or the Holders of the REMIC interests or the Certificates issued hereunder or the Trustee on behalf of such Holders.

Section 2.11. Acknowledgment of Transfer of Mortgage Pool Assets. The Trustee hereby acknowledges and accepts on behalf of the Trust the transfer and assignment pursuant to Section 2.04 to the Trust of the Mortgage Pool Assets, but without having made the review required to be made within 45 days pursuant to Section 2.07, and declares that as of the Closing Date it (or, with respect to the Mortgage Loans identified in the Initial Custodial Agreement, the Custodian on behalf of the Trustee) holds and shall hold any documents constituting a part of the Mortgage Pool Assets, and the Mortgage Pool Assets, as Trustee in trust, upon the trust herein set forth, for the use and benefit of all present and future Holders of the REMIC I Regular Interests, the Class PPP Certificates and the Class R-1 Residual Interest.

Section 2.12. Conveyance of REMIC II Assets; Security Interest. The Company does hereby irrevocably sell, transfer, assign, set over, and otherwise convey to the Trust, without recourse, all the Company’s right, title and interest in and to the REMIC II Assets. The Trust, as payment of the purchase price of the REMIC II Assets, shall issue the REMIC II Regular Interests and the Class R-2 Residual Interest to the Company on the Closing Date. Pursuant to Section 3818 of the Statutory Trust Statute, the REMIC I Regular Interests shall not be cancelled and shall be held as treasury interests owned by the Trust. The REMIC II Regular Interests and the Class R-2 Residual Interest shall together be a separate series of beneficial interests in the assets of the Trust consisting of the REMIC II Assets pursuant to Section 3806(b)(2) of the Statutory Trust Statute.

It is the express intent of the parties hereto that the conveyance of the REMIC II Assets to the Trust by the Company as provided in this Section 2.12 be, and be construed as, an absolute sale of the REMIC II Assets. It is, further, not the intention of the parties that such conveyance be deemed the grant of a security interest in the REMIC II Assets by the Company to the Trust to secure a debt or other obligation of the Company. However, in the event that, notwithstanding the intent of the parties, the REMIC II Assets are held to be the property of the Company, or if for any other reason this Agreement is held or deemed to create a security interest in the REMIC II Assets, then

(a) this Agreement shall constitute a security agreement;

(b) the conveyance provided for in this Section 2.12 shall be deemed to be a grant by the Company to the Trust of, and the Company hereby grants to the Trust, to secure all of the Company’s obligations hereunder, a security interest in all of the Company’s right, title, and interest, whether now owned or hereafter acquired, in and to:

(I) The REMIC I Regular Interests, including without limitation all rights represented thereby in and to the Mortgage Pool Assets and the proceeds thereof;

(III) All proceeds of the foregoing.

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

Section 2.13. REMIC Election for REMIC II.

The Servicer shall, on behalf of REMIC II, elect to treat REMIC II as a REMIC within the meaning of Section 860D of the Code and, if necessary, under applicable state laws. Such election shall be included in the Form 1066 and any appropriate state return to be filed on behalf of REMIC II for its first taxable year.

The Closing Date is hereby designated as the “startup day” of REMIC II within the meaning of Section 860G(a)(9) of the Code.

The regular interests (as set forth in the table contained in the Preliminary Statement hereto) relating to REMIC II are hereby designated as “regular interests” in REMIC II for purposes of Section 860G(a)(1) of the Code. The Class R-2 Residual Interest is hereby designated as the sole class of “residual interest” in REMIC II for purposes of Section 860G(a)(2) of the Code.

The parties intend that the affairs of REMIC II shall constitute, and that the affairs of REMIC II shall be conducted so as to qualify it as, a REMIC. In furtherance of such intention, the Servicer shall, on behalf of REMIC II: (a) prepare and file, or cause to be prepared and filed, a federal tax return using a calendar year as the taxable year for REMIC II when and as required by the REMIC provisions and other applicable federal income tax laws; (b) make an election, on behalf of REMIC II, to be treated as a REMIC on the federal tax return of REMIC II for its first taxable year, in accordance with the REMIC provisions; (c) prepare and forward, or cause to be prepared and forwarded, to the Certificateholders and the Holders of the Class R-2 Residual Interest all information reports as and when required to be provided to them in accordance with the REMIC provisions; (d) conduct the affairs of REMIC II at all times that any of the Certificates are outstanding so as to maintain the status of REMIC II as a REMIC under the REMIC provisions; (e) not knowingly or intentionally take any action or omit to take any action that would cause the termination of the REMIC status of REMIC II; and (f) pay the amount of any federal prohibited transaction penalty taxes imposed on REMIC II when and as the same shall be due and payable (but such obligation shall not prevent the Servicer or any other appropriate person from contesting any such tax in appropriate proceedings and shall not prevent the Servicer from withholding payment of such tax, if permitted by law, pending the outcome of such proceedings).

In the event that the Servicer has paid any federal prohibited transaction penalty taxes imposed on REMIC II pursuant to clause (f) of the immediately preceding paragraph, the Trustee on behalf of the Trust shall (unless the Servicer’s failure to exercise reasonable care was the primary cause of the imposition of such taxes) reimburse the Servicer, upon the written request of the Servicer, for such payment from amounts on deposit in the Certificate Account in reduction of the REMIC I Available Distribution Amount for the applicable Distribution Date. In the event that any federal prohibited transaction penalty taxes are imposed on REMIC II and not paid by the Servicer pursuant to clause (f) of the immediately preceding paragraph, the Trustee on behalf of the Trust shall pay such taxes from amounts on deposit in the Certificate Account in reduction of the REMIC I Available Distribution Amount for the applicable Distribution Date. The amount so reimbursed or paid pursuant to either of the immediately preceding two sentences shall be allocated as a loss to the Class R-1 Residual Interest, in reduction of the Class Principal Balance thereof.

Neither the Trustee nor the Tax Matters Person shall knowingly or intentionally take any action that would cause the termination of the REMIC status of REMIC II.

Section 2.14. Acknowledgement of Transfer of REMIC II Assets. The Trustee hereby acknowledges and accepts on behalf of the Trust the assignment to the Trust pursuant to Section 2.12 of the REMIC II Assets and declares that as of the Closing Date it holds and shall hold any documents constituting a part of the REMIC II Assets, and the REMIC II Assets, as Trustee in trust, upon the trust herein set forth, for the use and benefit of all present and future Holders of the REMIC II Regular Interests and the Class R-2 Residual Interest.

Section 2.15. Conveyance of Class A-3-M and Class A-5-M Regular Interests; Security Interest. The Company does hereby irrevocably sell, transfer, assign, set over, and otherwise convey to the Trust, without recourse, all the Company’s right, title and interest in and to the Class A-3-M and Class A-5-M Regular Interests. The Trust, as payment of the purchase price of the Class A-3-M and Class A-5-M Regular Interests, shall issue the Class A-3 and Class A-5 Certificates to the Company or the Company’s designee on the Closing Date in Authorized Denominations. Pursuant to Section 3818 of the Statutory Trust Statute, the Class A-3-M and Class A-5-M Regular Interests shall not be cancelled and shall be held as treasury interests owned by the Trust. The Class A-3 and Class A-5 Certificates shall together be a separate series of beneficial interests in the assets of the Trust consisting of the Class A-3-M and Class A-5-M Regular Interests and the Yield Maintenance Agreement pursuant to Section 3806(b)(2) of the Statutory Trust Statute.

It is the express intent of the parties hereto that the conveyance of the Class A-3-M and Class A-5-M Regular Interests to the Trust by the Company as provided in this Section 2.15 be, and be construed as, an absolute sale of the Class A-3-M and Class A-5-M Regular Interests. It is, further, not the intention of the parties that such conveyance be deemed the grant of a security interest in the Class A-3-M and Class A-5-M Regular Interests by the Company to the Trust to secure a debt or other obligation of the Company. However, in the event that, notwithstanding the intent of the parties, the Class A-3-M and Class A-5-M Regular Interests are held to be the property of the Company, or if for any other reason this Agreement is held or deemed to create a security interest in the Class A-3-M and Class A-5-M Regular Interests, then

(a) this Agreement shall constitute a security agreement;

(b) the conveyance provided for in this Section 2.15 shall be deemed to be a grant by the Company to the Trust of, and the Company hereby grants to the Trust, to secure all of the Company’s obligations hereunder, a security interest in all of the Company’s right, title, and interest, whether now owned or hereafter acquired, in and to:

(I) The Class A-3-M and Class A-5-M Regular Interests, including without limitation all rights represented thereby in and to the REMIC I Regular Interests and the proceeds thereof;

(III) All proceeds of the foregoing.

The Company shall file such financing statements, and the Company and the Trustee acting on behalf of the Trust at the direction of the Company shall, to the extent consistent with this Agreement, take such other actions as may be necessary to ensure that, if this Agreement were found to create a security interest in the Class A-3-M and Class A-5-M Regular Interests, such security interest would be a perfected security interest of first priority under applicable law and will be maintained as such throughout the term of this Agreement. In connection herewith, the Trust shall have all of the rights and remedies of a secured party under the Uniform Commercial Code as in force in the relevant jurisdiction.

Section 2.16. Acknowledgement of Transfer of Class A-3-M and Class A-5-M Regular Interests. The Trustee hereby acknowledges and accepts on behalf of the Trust the assignment to the Trust pursuant to Section 2.15 of the Class A-3-M and Class A-5-M Regular Interests and declares that as of the Closing Date it holds and shall hold any documents constituting a part of the Class A-3-M and Class A-5-M Regular Interests, and the Class A-3-M and Class A-5-M Regular Interests, as Trustee in trust, upon the trust herein set forth, for the use and benefit of all present and future Holders of the Class A-3 and Class A-5 Certificates.

Section 2.17. Legal Title. Legal title to all assets of the Trust shall be vested at all times in the Trust as a separate legal entity.

Section 2.18. Compliance with ERISA Requirements. For purposes of ensuring compliance with the requirements of the “underwriter’s exemption” (U.S. Department of Labor Prohibited Transaction Exemption 2002-41, 67 Fed. Reg. 54487 (Aug. 22, 2002)), issued under ERISA, and for the avoidance of any doubt as to the applicability of other provisions of this Agreement, to the fullest extent permitted by applicable law and except as contemplated by this Agreement, the Trust shall not be a party to any merger, consolidation or reorganization, or liquidate or sell its assets.

Section 2.19. Additional Representation Concerning the Mortgage Loans. Based on the Seller’s obligation, pursuant to Section 3.3 of the Mortgage Loan Purchase Agreement, to repurchase or substitute for the affected Mortgage Loan in the event of a breach of the representation set forth in clauses (xxvii) or (xxviii) of such Section 3.3 thereof, the parties hereto agree and understand that it is not intended for the Mortgage Pool to include any Mortgage Loan that is a “high-cost home loan” as defined under the New Jersey Home Ownership Security Act of 2002, the New Mexico Home Loan Protection Act, the Massachusetts Predatory Home Loan Practices Act or the Indiana Home Loan Practices Act (Indiana Code, Section 24-9 et seq.).

Washington Mutual Bank shall act as Servicer to service and administer the Mortgage Loans on behalf of the Trust in accordance with the terms hereof, consistent with prudent mortgage loan servicing practices and (unless inconsistent with prudent mortgage loan servicing practices) in the same manner in which, and with the same care, skill, prudence and diligence with which, it services and administers similar mortgage loans for other portfolios, and shall have full power and authority to do or cause to be done any and all things in connection with such servicing and administration which a prudent servicer of mortgage loans would do under similar circumstances, including, without limitation, the power and authority to bring actions and defend the Mortgage Pool Assets on behalf of the Trust in order to enforce the terms of the Mortgage Notes. The Servicer may perform its servicing responsibilities through agents or independent contractors, but shall not thereby be released from any of its responsibilities hereunder and the Servicer shall diligently pursue all of its rights against such agents or independent contractors.

The Servicer shall make reasonable efforts to collect or cause to be collected all payments called for under the terms and provisions of the Mortgage Loans and shall, to the extent such procedures shall be consistent with this Agreement and the terms and provisions of any Primary Insurance Policy, any FHA insurance policy or VA guaranty, any hazard insurance policy, and federal flood insurance, cause to be followed such collection procedures as are followed with respect to mortgage loans comparable to the Mortgage Loans and held in portfolios of responsible mortgage lenders in the local areas where each Mortgaged Property is located. The Servicer shall enforce “due-on-sale” clauses with respect to the related Mortgage Loans, to the extent permitted by law, subject to the provisions set forth in Section 3.08.

Consistent with the foregoing, the Servicer may, in accordance with prudent mortgage loan servicing practices and subject to Section 3.20, (i) waive or cause to be waived any assumption fee or late payment charge in connection with the prepayment of any Mortgage Loan and (ii) only upon determining that the coverage of any applicable insurance policy or guaranty related to a Mortgage Loan will not be materially adversely affected, arrange a schedule, running for no more than 180 days after the first delinquent Due Date, for payment of any delinquent installment on any Mortgage Note or for the liquidation of delinquent items.

Consistent with the terms of this Section 3.01, 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 it has determined, exercising its good faith business judgment in the same manner as it would if it were the owner of the related Mortgage Loan, that the security for, and the timely and full collectability of, such Mortgage Loan would not be adversely affected by such waiver, modification, postponement or indulgence; provided, however, that (unless the Mortgagor is in default with respect to the Mortgage Loan or in the reasonable judgment of the Servicer such default is imminent) the Servicer shall not permit any modification with respect to any Mortgage Loan that would (i) change the applicable Mortgage Interest Rate, defer or forgive the payment of any principal or interest, reduce the outstanding principal balance (except for actual payments of principal) or extend the final maturity date with respect to such Mortgage Loan, or (ii) be inconsistent with the terms of any applicable Primary Insurance Policy, FHA insurance policy, VA guaranty, hazard insurance policy or federal flood insurance policy. Notwithstanding the foregoing, the Servicer shall not permit any modification with respect to any Mortgage Loan that would both constitute a sale or exchange of such Mortgage Loan within the meaning of Section 1001 of the Code (including any proposed, temporary or final regulations promulgated thereunder) (other than in connection with a proposed conveyance or assumption of such Mortgage Loan that is treated as a Principal Prepayment or in a default situation) and cause any REMIC to fail to qualify as such under the Code. The Servicer shall be entitled to approve a request from a Mortgagor for a partial release of the related Mortgaged Property, the granting of an easement thereon in favor of another Person, any alteration or demolition of the related Mortgaged Property or other similar matters if it has determined, exercising its good faith business judgment in the same manner as it would if it were the owner of the related Mortgage Loan, that the security for, and the timely and full collectability of, such Mortgage Loan would not be adversely affected thereby and that REMIC I and REMIC II would not fail to continue to qualify as REMICs under the Code as a result thereof and that no tax on “prohibited transactions” or “contributions” after the startup day would be imposed on any REMIC as a result thereof.

The Servicer is hereby authorized and empowered by the Trust to, and shall, execute and deliver or cause to be executed and delivered on behalf of the Holders of the REMIC I Regular Interests and the Class R-1 Residual Interest, the Trustee and the Trust or any of them, any and all instruments of satisfaction or cancellation, or of partial or full release, discharge or modification, assignments of Mortgages and endorsements of Mortgage Notes in connection with refinancings (in jurisdictions where such assignments are the customary and usual standard of practice of mortgage lenders) and all other comparable instruments, with respect to the Mortgage Loans and with respect to the Mortgaged Properties. The Servicer is hereby further authorized and empowered by the Trust to execute and deliver or cause to be executed and delivered on behalf of the Holders of the REMIC I Regular Interests and the Class R-1 Residual Interest, the Trustee and the Trust, or any of them, such instruments of assignment or other comparable instruments as the Servicer shall, in its sole judgment, deem appropriate in order to register any Mortgage Loan on the MERS® System or to cause the removal of any Mortgage Loan from registration thereon. Any expenses incurred in connection with the actions described in the preceding sentence shall be borne by the Servicer with no right of reimbursement; provided, however, that any such expenses incurred as a result of any termination by MERS of the MERS® System shall be reimbursable to the Servicer. The Trustee on behalf of the Trust shall execute and furnish to the Servicer, at the Servicer’s direction, any powers of attorney and other documents prepared by the Servicer and determined by the Servicer to be necessary or appropriate to enable the Servicer to carry out its supervisory, servicing and administrative duties under this Agreement.

The Servicer shall obtain (to the extent generally commercially available) and maintain fidelity bond and errors and omissions coverage acceptable to Xxxxxx Xxx or Freddie Mac with respect to its obligations under this Agreement. The Servicer shall establish escrow accounts for, or pay when due (by means of an advance), any tax liens in connection with the Mortgaged Properties and premiums with respect to any insurance required to be maintained by the Servicer under Section 3.06 and 3.07, to the extent that such amounts are not paid by the Mortgagors when due and to the extent that any such payment would not constitute a Nonrecoverable Advance when made.

In connection with the servicing and administering of each Mortgage Loan, the Servicer and any affiliate of the Servicer (i) may perform services such as appraisals, default management and (in the case of affiliates only) brokerage services that are not customarily provided by servicers of mortgage loans, and shall be entitled to reasonable compensation therefor and (ii) may, at its own discretion and on behalf of the Trust, obtain credit information in the form of a “credit score” from a credit repository.

Section 3.02. The Custodial Accounts for P&I and Buydown Fund Accounts. The Servicer shall establish and maintain the Custodial Accounts for P&I and shall deposit or cause to be deposited therein within 48 hours of receipt the following amounts received or advanced by the Servicer with respect to the Mortgage Loans:

(i) all scheduled payments of principal;

(ii) all scheduled payments of interest, net of the Servicing Fees (to the extent not applied to pay Compensating Interest);

(iii) all Curtailments and Payoffs;

(iv) all Insurance Proceeds (except Insurance Proceeds required for the restoration or repair of the related Mortgaged Property, which shall be retained by the Servicer in an escrow account established for such purpose and maintained in an Eligible Institution, and which may, at the Servicer’s option, be invested in Eligible Investments), Liquidation Proceeds, Excess Liquidation Proceeds and Subsequent Recoveries;

(v) all Repurchase Proceeds; and

(vi) (a) all Prepayment Premiums collected on the Mortgage Loans, (b) all payments made by the Servicer in respect of Prepayment Premiums pursuant to Section 3.20 and (c) all payments received by the Servicer from the Seller in respect of Prepayment Premiums pursuant to Section 3.4 of the Mortgage Loan Purchase Agreement.

The Servicer shall not be required to deposit or cause to be deposited in the Custodial Accounts for P&I the additional servicing compensation described in the second sentence of the definition of “Servicing Fee.”

In the event that Buydown Funds have been provided with respect to any Mortgage Loan, the Servicer shall deposit such Buydown Funds in Buydown Fund Accounts established and maintained by the Servicer.

The Servicer is hereby authorized to make withdrawals from and to issue drafts against the Custodial Accounts for P&I and the Buydown Fund Accounts for the purposes required or permitted by this Agreement.

The Servicer hereby undertakes to assure remittance to the Certificate Account of all amounts relating to the Mortgage Loans that have been collected by the Servicer and are due to the Certificate Account pursuant to Section 4.01 of this Agreement.

Funds held in the Custodial Account for P&I may, at the Servicer’s option, be invested in (i) one or more Eligible Investments which shall in no event mature later than the Business Day prior to the Distribution Date on which such funds are required to be distributed to pursuant to Article IV (except if such Eligible Investments are obligations of the institution acting as the Trustee, in which case such Eligible Investments may mature on such Distribution Date), or (ii) such other instruments as shall be required to maintain the Ratings.

Section 3.03. The Investment Account; Eligible Investments.

(a) At its option, the Servicer may invest funds withdrawn from the Custodial Accounts for P&I or the Buydown Fund Accounts for its own account and at its own risk, during any period prior to their deposit in the Certificate Account pursuant to Section 3.04. Funds so withdrawn shall immediately be deposited by the Servicer with the Investment Depository in the Investment Account in the name of the Servicer and the Trust for investment only as set forth in this Section 3.03. The Servicer shall bear any and all losses incurred on any investments made with such funds and shall be paid all gains realized on such investments (except Payoff Earnings to the extent applied to pay Compensating Interest) as additional servicing compensation.

(b) Funds held in the Investment Account shall be invested in (i) one or more Eligible Investments which shall in no event mature later than the Business Day prior to the Distribution Date on which such funds are required to be distributed pursuant to Article IV (except if such Eligible Investments are obligations of the institution acting as the Trustee, in which case such Eligible Investments may mature on such Distribution Date), or (ii) such other instruments as shall be required to maintain the Ratings.

Section 3.04. The Certificate Account.

(a) On or prior to the Closing Date, the Trustee shall establish or cause to be established the Certificate Account. Promptly after the Closing Date, the Trustee shall communicate to the Servicer the account number and wiring instructions for the Certificate Account.

(b) Not later than the Business Day prior to each Distribution Date, the Servicer shall direct the Investment Depository to withdraw from the Investment Account and deposit in the Certificate Account (or, in the event any such amounts have not been deposited in the Investment Account, the Servicer shall withdraw from the Custodial Accounts for P&I or the Buydown Fund Accounts, as applicable, and deposit in the Certificate Account) the following amounts (in each case, net of any amounts that the Servicer is entitled to withdraw from the Custodial Accounts for P&I pursuant to Section 3.05(a)(i) through (v)):

(i) Scheduled installments of principal and interest on the Mortgage Loans received by the Servicer which were due on or before the related Due Date;

(ii) Payoffs received by the Servicer during the related Payoff Period, with interest to the date of Payoff;

(iii) Curtailments, Insurance Proceeds (except Insurance Proceeds required for the restoration or repair of the related Mortgaged Property), Liquidation Proceeds, Excess Liquidation Proceeds, Subsequent Recoveries and Repurchase Proceeds received by the Servicer during the Prior Period;

(iv) the Assigned Prepayment Premiums for such Distribution Date;

(v) any Monthly P&I Advance required to be made by the Servicer for such Distribution Date;

(vi) amounts paid by the Servicer in connection with the exercise of its option to terminate this Agreement pursuant to Section 9.01; and

(vii) any other amounts required to be distributed from the Certificate Account on such Distribution Date pursuant to Article IV (other than amounts to be deposited in the Certificate Account by the Trustee pursuant to clause (c) of this Section 3.04).

(c) On each Distribution Date, the Trustee shall deposit in the Certificate Account amounts withdrawn from the Yield Maintenance Account, in accordance with Section 3.16.

(d) Funds held in the Certificate Account shall be invested at the written direction of the Servicer in (i) one or more Eligible Investments which shall in no event mature later than the Business Day prior to the related Distribution Date (except if such Eligible Investments are obligations of the institution acting as the Trustee, such Eligible Investments may mature on the Distribution Date), or (ii) such other instruments as shall be required to maintain the Ratings. The Servicer shall be entitled to be paid as additional servicing compensation any gains earned on such Eligible Investments and shall bear any losses suffered in connection therewith. If the Trustee has not received such written investment directions from the Servicer, the Trustee shall not invest funds held in the Certificate Account. The Trustee shall have no liability for any losses on investments of funds held in the Certificate Account.

Section 3.05. Permitted Withdrawals from the Certificate Account, the Investment Account, the Custodial Accounts for P&I and the Buydown Fund Accounts.

(a) The Servicer is authorized to make withdrawals (or, in the case of the Certificate Account, to direct the Trustee to make withdrawals), from time to time, from the Investment Account, the Certificate Account or the Custodial Accounts for P&I of amounts deposited therein, as follows:

(i) To reimburse itself for the following amounts advanced by the Servicer, to the extent that such amounts have not been previously reimbursed or otherwise recovered by the Servicer: (a) Monthly P&I Advances made pursuant to Section 4.02, (b) amounts advanced with respect to the payment of taxes pursuant to the sixth paragraph of Section 3.01, (c) amounts advanced to maintain any required insurance pursuant to Sections 3.06 and 3.07 and (d) amounts expended by or for the account of the Servicer pursuant to Section 3.09 in connection with foreclosure or bankruptcy proceedings or the maintenance or restoration of Mortgaged Properties,such right to reimbursement pursuant to this paragraph (i) being limited to amounts (including late Monthly Payments, Insurance Proceeds and Liquidation Proceeds) received on the particular Mortgage Loan with respect to which such advances were made;

(ii) To reimburse itself for amounts advanced by the Servicer that the Servicer has determined to be Nonrecoverable Advances;

(iii) To pay to itself the sum of the Servicing Fees and any Payoff Interest (net of Compensating Interest reduced by Payoff Earnings) for the related Distribution Date;

(iv) To pay to itself the amount of any reinvestment earnings deposited or earned in the Investment Account or the Certificate Account (reduced by the lesser of Payoff Earnings and Compensating Interest for the related Distribution Date);

(v) To reimburse itself or the Company for expenses incurred by and reimbursable to it or the Company pursuant to Section 6.03;

(vi) To pay on behalf of the Trust any Special Primary Insurance Premium payable by the Trust pursuant to Section 4.04(a); provided, the Servicer shall give written notice thereof to the Trustee prior to noon New York City time two Business Days prior to the applicable Distribution Date;

(vii) To make any deposit, required or permitted hereunder, of withdrawn funds to the Investment Account or the Certificate Account; and

after making or providing for the above withdrawals

(viii) To clear and terminate the Investment Account and the Certificate Account following termination of this Agreement pursuant to Section 9.01.

Since, in connection with withdrawals pursuant to Section 3.05(a)(i), the Servicer’s entitlement thereto is limited to collections or other recoveries on the related Mortgage Loan, the Servicer shall keep and maintain, separate accounting for each Mortgage Loan, for the purpose of justifying any such withdrawals.

(b) The Servicer is authorized to make withdrawals, from time to time, of Buydown Funds from the Buydown Fund Accounts or Custodial Accounts for P&I (and, to the extent applicable, to make deposits of the amounts withdrawn), as follows:

(i) To deposit each month in the Investment Account or the Certificate Account the amount necessary to supplement payments received on Buydown Loans;

(ii) In the event of a Payoff of any Mortgage Loan having a related Buydown Fund, to apply amounts remaining in Buydown Fund Accounts to reduce the required amount of such principal Payoff (or, if the Mortgagor has made a Payoff, to refund such remaining Buydown Fund amounts to the Person entitled thereto);

(iii) In the event of foreclosure or liquidation of any Mortgage Loan having a Buydown Fund, to deposit remaining Buydown Fund amounts in the Investment Account or the Certificate Account as Liquidation Proceeds; and

(iv) To clear and terminate the portion of any account representing Buydown Funds following termination of this Agreement pursuant to Section 9.01.

(c) The Trustee is authorized to make withdrawals from time to time from the Certificate Account to reimburse itself for advances it has made as successor Servicer pursuant to Section 7.01(a) hereof that it has determined to be Nonrecoverable Advances.

Section 3.06. Maintenance of Primary Insurance Policies; Collections Thereunder. The Servicer shall use commercially reasonable efforts to keep in full force and effect each Primary Insurance Policy (except any Special Primary Insurance Policy) required with respect to a Mortgage Loan until no longer required, and the Servicer shall use commercially reasonable efforts to keep in full force and effect each Special Primary Insurance Policy, if any. Notwithstanding the foregoing, the Servicer shall have no obligation to maintain any Primary Insurance Policy for a Mortgage Loan for which the outstanding Principal Balance thereof at any time subsequent to origination was 80% or less of the Appraised Value of the related Mortgaged Property, unless required by applicable law.

Unless required by applicable law, the Servicer shall not cancel or refuse to renew any Primary Insurance Policy in effect at the date of the initial issuance of the Certificates that is required to be kept in force hereunder; provided, however, that the Servicer shall not advance funds for the payment of any premium due under (i) any Primary Insurance Policy (other than a Special Primary Insurance Policy) if it shall determine that such an advance would be a Nonrecoverable Advance or (ii) any Special Primary Insurance Policy.

Section 3.07. Maintenance of Hazard Insurance. The Servicer shall cause to be maintained for each Mortgage Loan (other than a Cooperative Loan) hazard insurance with extended coverage in an amount which is not less than the original principal balance of such Mortgage Loan, except in cases approved by the Servicer in which such amount exceeds the value of the improvements to the Mortgaged Property. The Servicer shall also require hazard insurance with extended coverage in a comparable amount on property acquired upon foreclosure, or deed in lieu of foreclosure, of any Mortgage Loan (other than a Cooperative Loan). Any amounts collected under any such policies (other than amounts to be applied to the restoration or repair of the related Mortgaged Property) shall be deposited into the Custodial Account for P&I, subject to withdrawal pursuant to Section 3.03 and Section 3.05. Any unreimbursed costs incurred in maintaining any insurance described in this Section 3.07 shall be recoverable as an advance by the Servicer pursuant to Section 3.05(a). Such insurance shall be with insurers approved by the Servicer or Xxxxxx Xxx or Freddie Mac. Other additional insurance may be required of a Mortgagor pursuant to such applicable laws and regulations as shall at any time be in force and as shall require such additional insurance. Where any part of any improvement to the Mortgaged Property (other than a Mortgaged Property secured by a Cooperative Loan) is located in a federally designated special flood hazard area and in a community which participates in the National Flood Insurance Program at the time of origination of the related Mortgage Loan, the Servicer shall cause flood insurance to be provided. The hazard insurance coverage required by this Section 3.07 may be met with blanket policies providing protection equivalent to individual policies otherwise required. The Servicer agrees to present, or cause to be presented, on behalf of and for the benefit of the Trust, claims under the hazard insurance policy respecting any Mortgage Loan, and in this regard to take such reasonable actions as shall be necessary to permit recovery under such policy.

Section 3.08. Enforcement of Due-on-Sale Clauses; Assumption Agreements. When any Mortgaged Property is about to be conveyed by the Mortgagor, the Servicer shall, to the extent it has knowledge of such prospective conveyance and prior to the time of the consummation of such conveyance, exercise on behalf of the Trust the Trust’s rights to accelerate the maturity of such Mortgage Loan, to the extent that such acceleration is permitted by the terms of the related Mortgage Note, under any “due-on-sale” clause applicable thereto; provided, however, that the Servicer shall not exercise any such right if the due-on-sale clause, in the reasonable belief of the Servicer, is not enforceable under applicable law or if such exercise would result in non-coverage of any resulting loss that would otherwise be covered under any insurance policy. In the event the Servicer is prohibited from exercising such right, the Servicer is authorized to take or enter into an assumption and modification agreement from or with the Person to whom a Mortgaged Property has been or is about to be conveyed, pursuant to which such Person becomes liable under the Mortgage Note and, unless prohibited by applicable state law or unless the Mortgage Note contains a provision allowing a qualified borrower to assume the Mortgage Note, the Mortgagor remains liable thereon; provided that the Mortgage Loan shall continue to be covered (if so covered before the Servicer enters such agreement) by any related Primary Insurance Policy. The Servicer is also authorized to enter into a substitution of liability agreement with such Person, pursuant to which the original Mortgagor is released from liability and such Person is substituted as Mortgagor and becomes liable under the Mortgage Note. The Servicer shall not enter into any substitution or assumption with respect to a Mortgage Loan if such substitution or assumption shall (i) both constitute a “significant modification” effecting an exchange or reissuance of such Mortgage Loan under the Code (or Treasury regulations promulgated thereunder) and cause the REMICs to fail to qualify as a REMIC under the REMIC Provisions or (ii) cause the imposition of any tax on “prohibited transactions” or “contributions” after the startup day under the REMIC Provisions. The Servicer shall notify the Trustee that any such substitution or assumption agreement has been completed by forwarding to the Trustee (or, if applicable, the Custodian) the original copy of such substitution or assumption agreement and other documents and instruments constituting a part thereof. In connection with any such assumption or substitution agreement, the terms of the related Mortgage Note shall not be changed. Any fee collected by the Servicer for entering into an assumption or substitution of liability agreement shall be paid to the Servicer as additional servicing compensation.

Notwithstanding the foregoing paragraph or any other provision of this Agreement, the Servicer shall not be deemed to be in default, breach or otherwise in violation of any of its obligations hereunder by reason of any assumption of a Mortgage Loan by operation of law or any assumption which the Servicer may be restricted by law from preventing, for any reason whatsoever.

Section 3.09. Realization Upon Defaulted Mortgage Loans. The Servicer shall foreclose upon or otherwise comparably convert, or cause to be foreclosed upon or comparably converted, the ownership of any Mortgaged Property securing a Mortgage Loan which comes into and continues in default and as to which no satisfactory arrangements can be made for collection of delinquent payments pursuant to Section 3.01. In lieu of such foreclosure or other conversion, and taking into consideration the desirability of maximizing net Liquidation Proceeds and Insurance Proceeds, the Servicer may, to the extent consistent with prudent mortgage loan servicing practices, accept a payment of less than the outstanding Principal Balance of a delinquent Mortgage Loan in full satisfaction of the indebtedness evidenced by the related Mortgage Note and release the lien of the related Mortgage upon receipt of such payment. The Servicer shall not foreclose upon or otherwise comparably convert a Mortgaged Property if the Servicer is aware of evidence of toxic waste, other hazardous substances or other evidence of environmental contamination thereon and the Servicer determines that it would be imprudent to do so. In connection with such foreclosure or other conversion, the Servicer shall cause to be followed such practices and procedures as it shall deem necessary or advisable and as shall be normal and usual in general mortgage servicing activities. The Servicer shall be responsible for all costs and expenses incurred by it in any such foreclosure proceedings or in any bankruptcy proceedings with respect to a Mortgagor, and the costs and expenses of maintaining or restoring any Mortgaged Property securing a defaulted Mortgage Loan; provided, however, that it shall be entitled to reimbursement thereof (as well as its normal servicing compensation) as an advance. The foregoing is subject to the provision that, in the case of damage to a Mortgaged Property from an Uninsured Cause, the Servicer shall not advance funds towards the restoration of the property unless it shall be determined, in the sole judgment of the Servicer, (i) that such restoration will increase the proceeds of liquidation of the Mortgage Loan to Certificateholders after reimbursement to itself for such expenses, and (ii) that such expenses will be recoverable to it through Liquidation Proceeds. The Servicer shall maintain information required for tax reporting purposes regarding any Mortgaged Property which is abandoned or which has been foreclosed or otherwise comparably converted. The Servicer shall report such information to the Internal Revenue Service and the Mortgagor in the manner required by applicable law.

The Servicer may enter into one or more special servicing agreements with a Lowest Class B Owner, subject to each Rating Agency’s acknowledgment that the Ratings of the Certificates in effect immediately prior to the entering into of such agreement would not be qualified, downgraded or withdrawn and the Certificates would not be placed on credit review status (except for possible upgrading) as a result of such agreement. Any such agreement may contain provisions whereby such Lowest Class B Owner may (a) instruct the Servicer to commence or delay foreclosure proceedings with respect to delinquent Mortgage Loans, provided that the Lowest Class B Owner deposits a specified amount of cash with the Servicer that will be available for distribution to Certificateholders if Liquidation Proceeds are less than they otherwise may have been had the Servicer acted pursuant to its normal servicing procedures, (b) purchase such delinquent Mortgage Loans from the Trust immediately prior to the commencement of foreclosure proceedings at a price equal to the aggregate outstanding Principal Balance of such Mortgage Loans plus accrued interest thereon at the applicable Mortgage Interest Rate through the last day of the month in which such Mortgage Loans are purchased plus any unreimbursed advances made by the Servicer hereunder; and/or (c) assume all of the servicing rights and obligations with respect to such delinquent Mortgage Loans so long as (i) the Servicer has the right to transfer the servicing rights and obligations of such Mortgage Loans to another servicer and (ii) such Lowest Class B Owner will service such Mortgage Loans in accordance with the terms of this Agreement; provided, however, that no such agreement will relieve the Servicer of any of its obligations hereunder.

REMIC I shall not acquire any real property (or personal property incident to such real property) except in connection with a default or imminent default of a Mortgage Loan. In the event that REMIC I acquires any real property (or personal property incident to such real property) in connection with a default or imminent default of a Mortgage Loan, such property shall be disposed of by the Servicer as soon as practicable in a manner that, consistent with prudent mortgage loan servicing practices, maximizes the net present value of the recovery to the Trust, but in any event within three years after its acquisition by the Servicer for REMIC I unless the Servicer provides to the Trustee an Opinion of Counsel to the effect that the holding by REMIC I of such Mortgaged Property subsequent to three years after its acquisition will not result in the imposition of taxes on “prohibited transactions” of REMIC I as defined in Section 860F of the Code or under the law of any state in which real property securing a Mortgage Loan owned by REMIC I is located or cause REMIC I to fail to qualify as a REMIC for federal income tax purposes or for state tax purposes under the laws of any state in which real property securing a Mortgage Loan owned by REMIC I is located at any time that any Certificates are outstanding. The Servicer shall conserve, protect and operate each such property for the Certificateholders solely for the purpose of its prompt disposition and sale in a manner which does not cause such property to fail to qualify as “foreclosure property” within the meaning of Section 860G(a)(8) or result in the receipt by the REMIC of any “income from non-permitted assets” within the meaning of Section 860F(a)(2)(B) of the Code or any “net income from foreclosure property” which is subject to taxation under the REMIC Provisions. Pursuant to its efforts to sell such property, the Servicer shall either itself or through an agent selected by the Servicer protect and conserve such property in the same manner and to such extent as is customary in the locality where such property is located and may, incident to its conservation and protection of the assets of the Trust, rent the same, or any part thereof, as the Servicer deems to be in the best interest of the Trust for the period prior to the sale of such property. Additionally, the Servicer shall perform the tax withholding and shall file information returns with respect to the receipt of mortgage interests received in a trade or business, the reports of foreclosures and abandonments of any Mortgaged Property and the information returns relating to cancellation of indebtedness income with respect to any Mortgaged Property required by Sections 6050H, 6050J and 6050P, respectively, of the Code, and deliver to the Trustee an Officers’ Certificate on or before March 31 of each year stating that such reports have been filed. Such reports shall be in form and substance sufficient to meet the reporting requirements imposed by Sections 6050H, 6050J and 6050P of the Code.

Notwithstanding any other provision of this Agreement, the Servicer and the Trustee, as applicable, shall comply with all federal withholding requirements with respect to payments to Certificateholders of interest or original issue discount that the Servicer or the Trustee reasonably believes are applicable under the Code. The consent of Certificateholders shall not be required for any such withholding. Without limiting the foregoing, the Servicer shall not withhold with respect to payments of interest or original issue discount in the case of a Certificateholder that has furnished or caused to be furnished an effective Form W-8 or an acceptable substitute form or a successor form and who is not a “10 percent shareholder” within the meaning of Code Section 871(h)(3)(B) or a “controlled foreign corporation” described in Code Section 881(c)(3)(C) with respect to REMIC I, REMIC II or the Company. In the event the Trustee withholds any amount from interest or original issue discount payments or advances thereof to any Certificateholder pursuant to federal withholding requirements, the Trustee shall indicate the amount withheld to such Certificateholder.

Section 3.10. Trustee to Cooperate; Release of Mortgage Files. Upon the Payoff or scheduled maturity of any Mortgage Loan, the Servicer shall cause such final payment to be deposited within 48 hours in the related Custodial Account for P&I. The Servicer shall promptly notify the Trustee thereof by a certification (which certification shall include a statement to the effect that all amounts received in connection with such payment which are required to be deposited in such account have been so deposited) of a Servicing Officer and shall request delivery to it of the Mortgage File; provided, however, that such certification shall not be required if the Mortgage File is held by a Custodian which is also the Servicer of the Mortgage Loan. Upon receipt of such certification and request, the Trustee shall (or, if applicable, shall cause the Custodian in accordance with the Custodial Agreement to), not later than the fifth succeeding Business Day, release, or cause to be released, the related Mortgage File to the Servicer. With any such Payoff or other final payment, the Servicer is authorized (i) to prepare for and procure from the trustee or mortgagee under the Mortgage which secured the Mortgage Note a deed of full reconveyance or other form of satisfaction or assignment of Mortgage and endorsement of Mortgage Note in connection with a refinancing covering the Mortgaged Property, which satisfaction, endorsed Mortgage Note or assigning document shall be delivered by the Servicer to the person or persons entitled thereto, and (ii) with respect to any MERS Loan, to cause the removal of such Mortgage Loan from registration on the MERS® System. No expenses incurred in connection with such satisfaction or assignment shall be payable to the Servicer by the Trustee or from the Certificate Account, the related Investment Account or the related Custodial Account for P&I. From time to time as appropriate for the servicing or foreclosure of any Mortgage Loan, including, for this purpose, collection under any Primary Insurance Policy, the Trustee shall (or, if applicable, shall cause the Custodian in accordance with the Custodial Agreement to), upon request of the Servicer and delivery to it of a trust receipt signed by a Servicing Officer, release not later than the fifth Business Day following the date of receipt of such request and trust receipt the related Mortgage File to the Servicer and shall execute such documents as shall be necessary to the prosecution of any such proceedings. Such trust receipt shall obligate the Servicer to return the Mortgage File to the Trustee (or, if applicable, the Custodian) when the need therefor by the Servicer no longer exists, unless the Mortgage Loan shall be liquidated, in which case, upon receipt of a certificate of a Servicing Officer similar to that herein above specified, the trust receipt shall be released by the Trustee to the Servicer.

Section 3.11. Compensation to the Servicer. As compensation for its activities hereunder, the Servicer shall be entitled to receive from the accounts listed in Section 3.05(a) the amounts provided for by Section 3.05(a)(iii). In addition, the Servicer shall be entitled to be paid, as additional servicing compensation, (i) any prepayment penalty received on a Mortgage Loan that is not an Assigned Prepayment Premium, and any late charges, nonsufficient funds fees and other fees and charges collected on the Mortgage Loan, (ii) to the extent provided in Section 3.03, all gains realized on investments of funds held in the Investment Account and (iii) all gains realized on investments of funds held in the Certificate Account. The Servicer shall be required to pay all expenses incurred by it in connection with its activities hereunder and shall not be entitled to reimbursement therefor, except as specifically provided herein.

Section 3.12. [Reserved.]

Section 3.13. Annual Statement as to Compliance.

The Servicer shall deliver to the Company and the Trustee, on or before April 30 of each year, beginning with the first April 30 succeeding the Cut-Off Date by at least six months, an Officer’s Certificate stating as to the signer thereof, that (i) a review of the activities of the Servicer during the preceding calendar year (or the applicable portion thereof) and of its performance under this Agreement has been made under such officer’s supervision, and (ii) to the best of such officer’s knowledge, based on such review, the Servicer has fulfilled all its obligations under this Agreement in all material respects throughout such year (or the applicable portion thereof), or, if there has been a failure to fulfill any such obligation in any material respect, specifying each such failure known to such officer and the nature and status thereof. Copies of such statement shall be provided by the Servicer, or by the Trustee (solely to the extent that such copies are available to the Trustee) at the expense of the Servicer, to Certificateholders upon request.

Section 3.14. Access to Certain Documentation and Information Regarding the Mortgage Loans. In the event that the Certificates are legal for investment by federally-insured savings associations, the Servicer shall provide to the OTS, the FDIC and the supervisory agents and examiners of the OTS and the FDIC access to the documentation regarding the related Mortgage Loans required by applicable regulations of the OTS or the FDIC, as applicable, and shall in any event provide such access to the documentation regarding such Mortgage Loans to the Trustee and its representatives, such access being afforded without charge, but only upon reasonable request and during normal business hours at the offices of the Servicer designated by it.

Section 3.15. Annual Independent Public Accountants’ Servicing Report. On or before April 30 of each year, beginning with the first April 30 succeeding the Cut-Off Date by at least six months, the Servicer, at its expense, shall furnish to the Trustee a copy of a report delivered to the Servicer by a firm of independent public accountants (who may also render other services to the Servicer or any affiliate thereof) to the effect that, on the basis of an examination conducted by such firm in accordance with standards established by the American Institute of Certified Public Accountants, the Servicer has complied with certain minimum residential mortgage loan servicing standards in its role as Servicer with respect to the servicing of residential mortgage loans (including the Mortgage Loans) during the most recently completed fiscal year. In rendering its report such firm may rely, (a) as to matters relating to the Certificates, upon a statistical sampling of series of mortgage-backed certificates which may include the Certificates and (b) as to matters relating to the direct servicing of residential mortgage loans by subservicers, upon comparable reports of firms of independent certified public accountants rendered on the basis of examinations conducted in accordance with the same standards (rendered within one year of such report) with respect to those subservicers.

Section 3.16. Yield Maintenance Account. On or prior to the Closing Date, the Trustee shall cause to be established and maintained the Yield Maintenance Account, into which amounts received by the Trustee from the Cap Counterparty pursuant to the Yield Maintenance Agreements shall be deposited for the benefit of the Class A-3 and Class A-5 Certificates. On each Distribution Date, the Trustee shall withdraw from the Yield Maintenance Account to the extent funds are available therein and in accordance with the statement received from the Servicer pursuant to Section 4.02(b), the Yield Maintenance Payment Amounts for the Class A-3 and Class A-5 Certificates for such Distribution Date, and deposit such amounts in the Certificate Account for payment to such Classes of Certificates pursuant to Section 4.04(a).

Amounts on deposit in the Yield Maintenance Account shall not be invested and shall not be held in an interest-bearing account.

The Trustee shall withdraw from the Yield Maintenance Account and pay to itself any amounts remaining in the Yield Maintenance Account after the later of the Final Yield Maintenance Payment Date for the Class A-3 and Class A-5 Certificates.

To the extent that it constitutes a “reserve fund” for purposes of the REMIC Provisions, the Yield Maintenance Account established hereunder shall be an “outside reserve fund” as defined in Treasury Regulation 1.860G-2(h), and in that regard (i) such fund shall be an outside reserve fund and not an asset of any REMIC, (ii) such fund shall be owned for federal tax purposes by the Trustee, and the Trustee shall report all amounts of income, deduction, gain or loss accruing therefrom, and (iii) amounts transferred by the REMIC to the fund shall be treated as distributed by the REMIC to the Trustee. The Servicer shall deliver to the Trustee an annual statement showing (x) the amounts received by the Trustee, in its capacity as owner of the Yield Maintenance Account for income tax purposes, as payments on the Yield Maintenance Agreements, and (y) the amounts paid to Certificateholders from such amounts received. The Servicer shall indemnify the Trustee to the extent that any tax liability of the Trustee, in its capacity as owner of the Yield Maintenance Account for income tax purposes (including the amount of any tax liability resulting from the indemnity payment), exceeds the net funds (that is, the excess of the amount in clause (x) above over the amount in clause (y) above), if any, received by the Trustee from such account.

Section 3.17. [Reserved.]

Section 3.18. [Reserved.]

Section 3.19. Determination of LIBOR by Servicer.

(a) With respect to the first Distribution Date, LIBOR shall be 4.370%. With respect to each Distribution Date thereafter, the Servicer will determine LIBOR on the related LIBOR Determination Date on the basis of the “Interest Settlement Rate” for United States dollar deposits of one-month maturity set by the British Bankers’ Association (the “BBA”) as of 11:00 a.m. (London time) on such LIBOR Determination Date as found on any of the Moneyline Telerate Service (formerly the Dow Xxxxx Markets) page 3750, the Reuters Monitor Money Rates Service page “LIBOR01” or the Bloomberg L.P. page “BBAM” (each such page, or such other page as may replace any of the foregoing on such service or such other service as may be nominated by the BBA as the information vendor for the purpose of displaying the BBA’s Interest Settlement Rates for deposits in United States dollars, each, a “Designated Telerate Page”).

(b) If on any LIBOR Determination Date, such Interest Settlement Rates are not available from any Designated Telerate Page, LIBOR for the related accrual period will be the most recently published Interest Settlement Rate. In the event that the BBA no longer sets an Interest Settlement Rate, the Servicer shall calculate LIBOR for the immediately following accrual period as follows: the Servicer will determine LIBOR by reference to the quotations offered by the principal London office of each of the designated Reference Banks meeting the criteria set forth below for making one-month United States dollar deposits in leading banks in the London Interbank market, as of 11:00 a.m. (London time) on the LIBOR Determination Date. Under this method LIBOR will be established by the Servicer on each LIBOR Determination Date as follows:

(i) If on any LIBOR Determination Date two or more Reference Banks provide offered quotations, LIBOR for the next interest accrual period shall be the arithmetic mean of the offered quotations, carrying the result (expressed as a percentage) out to six decimal places, and rounding to five decimal places.

(ii) If on any LIBOR Determination Date only one or none of the Reference Banks provides offered quotations, LIBOR for the next interest accrual period shall be the greater of:

(A) LIBOR as determined on the previous LIBOR Determination Date (or, in the case of the first LIBOR Determination Date, the applicable LIBOR as specified in the first sentence of Section 3.19(a)) and

(B) the Reserve Interest Rate.

The “Reserve Interest Rate” shall be the rate per annum that the Servicer determines to be either:

(A) the arithmetic mean, (expressed as a percentage) carried out to six decimal places, and rounded to five decimal places, of the one-month United States dollar lending rates that New York City banks selected by the Servicer are quoting, on the relevant LIBOR Determination Date, to the principal London offices of at least two of the Reference Banks to which the quotations are, in the opinion of the Servicer, being so made, or

(B) if the Servicer cannot determine the arithmetic mean, the lowest one-month United States dollar lending rate which New York City banks selected by the Servicer are quoting on the LIBOR Determination Date to leading European banks.

(iii) If on any LIBOR Determination Date the Servicer is required but is unable to determine the Reserve Interest Rate in the manner provided in paragraph (ii) above, LIBOR for the next interest accrual period shall be LIBOR as determined on the preceding LIBOR Determination Date (or, in the case of the first LIBOR Determination Date, the applicable LIBOR as specified in the first sentence of Section 3.19(a)).

Each “Reference Bank” (i) will be a leading bank engaged in transactions in Eurodollar deposits in the international Eurocurrency market, (ii) will not control, be controlled by, or be under common control with, the Servicer and (iii) will have an established place of business in London. If any Reference Bank should be unwilling or unable to act as such or if the Servicer should terminate the designation of any such reference bank, the Servicer will promptly designate another leading bank meeting the criteria specified above. If on any such LIBOR Determination Date, the Servicer calculates LIBOR on the basis of the provisions of this Section 3.19(b), the Servicer shall designate the Reference Banks.

(c) The establishment of LIBOR on each LIBOR Determination Date by the Servicer for the related accrual period will, in the absence of manifest error, be final and binding.

Section 3.20. Assigned Prepayment Premiums.

(a) Notwithstanding anything in this Agreement to the contrary, in the event of a voluntary Payoff, the Servicer may not waive any Prepayment Premium or portion thereof required by the terms of the related Mortgage Note:

(1) unless the related Mortgage Loan is in default or default is foreseeable and such waiver (i) is standard and customary in servicing mortgage loans similar to the Mortgage Loans and (ii) would, in the reasonable judgment of the Servicer, maximize recovery of total proceeds taking into account the value of such Prepayment Premium and the related Mortgage Loan,

(2) unless (i) the enforceability thereof is limited (A) by bankruptcy, insolvency, moratorium, receivership, or other similar law relating to creditors’ rights generally or (B) due to acceleration in connection with a foreclosure or other involuntary payment or (ii) the enforceability is otherwise limited or prohibited by applicable law,

(3) unless the enforceability would be considered “predatory” pursuant to written guidelines issued by any applicable federal, state or local authority having jurisdiction over such matters,

(4) unless the Servicer is unable to locate documentation sufficient to allow it to confirm the existence and amount of such Prepayment Premium after using commercially reasonable efforts to locate such documentation, which efforts shall include, but are not limited to, seeking such documentation from the Company, the Custodian and from its own records or files,

(5) unless the Mortgagor sells the Mortgaged Property and obtains a new mortgage loan originated and serviced by Washington Mutual Bank to purchase another property, provided that the prepayment is made no earlier than one year after origination,

(6) unless the Payoff is made using the proceeds of another mortgage loan originated by the Servicer within 90 days of the end of the prepayment penalty term of the Mortgage Loan if such mortgage loan qualifies under the Servicer’s then current policies for the administration of prepayment penalties for mortgage loans of the same type as the Mortgage Loan that the Servicer administers for its own account, or

(7) unless the Mortgage Loan is subject to the Relief Act at the time of such Payoff.

(b) If the Servicer has waived all or a portion of an Prepayment Premium relating to a voluntary Payoff in compliance with Section 3.20(a), then the Class PPP Certificateholders shall not be entitled to the amounts waived.

(c) Upon discovery by the Servicer, the Company or the Trustee (in the case of the Trustee, having actual knowledge thereof) of a breach of the provisions of Section 3.20(a), which materially and adversely affects the Holders of the Class PPP Certificates, the party discovering such breach shall give prompt written notice to the other parties. Within 60 days of the earlier of discovery by the Servicer, the Company or the Trustee, as applicable, of such breach, the Servicer shall cure such breach in all material respects or, if the breach cannot be cured, shall deposit, or cause to be deposited, to the Custodial Account the amount of each impermissibly waived Prepayment Premium (less any amount collected from the Mortgagor in respect to such Prepayment Premium); provided, however, that the Servicer shall not be obligated to deposit the amount of any impermissibly waived Prepayment Premium if the failure to collect such amount is the direct result of inaccurate or incomplete information related to the Prepayment Premium in effect at such time.

Upon discovery by the Servicer, the Company or the Trustee (in the case of the Trustee, having actual knowledge thereof) of a breach by the Seller of any of the representations and warranties set forth in Section 3.4(b) of the Mortgage Loan Purchase Agreement, which materially and adversely affects the Holders of the Class PPP Certificates, the party discovering such breach shall give prompt written notice to the other parties. The Servicer shall promptly notify the Seller of such breach and take appropriate steps on behalf of the Trust to enforce the Seller’s obligation, pursuant to Section 3.4(c) of the Mortgage Loan Purchase Agreement, to pay to the Trust the amount of each Prepayment Premium that would have been collected had each such representation and warranty referred to in this paragraph been true (less any amount collected from the related Mortgagor with respect to such Prepayment Premium). The Servicer shall deposit, or cause to be deposited, to the Custodial Account for P&I within 48 hours or receipt the amounts so received from the Seller.

Section 4.01. Distributions to Holders of REMIC I Regular Interests and Class R-1 Residual Interest . On each Distribution Date, the Trustee (or any duly appointed paying agent) on behalf of the Trust (i) shall be deemed to have distributed from the Certificate Account the REMIC I Distribution Amount to the Holders of the REMIC I Regular Interests, and to have deposited such amounts for their benefit into the Certificate Account and (ii) from the Certificate Account shall distribute to the Class R Certificateholders, in accordance with the written statement received from the Servicer pursuant to Section 4.02(b), the sum of (a) the Excess Liquidation Proceeds and (b) the amounts to be distributed to the Holders of the Class R-1 Residual Interest pursuant to the definition of “REMIC I Distribution Amount” for such Distribution Date.

The Servicer’s obligation to make any advance or advances described in this Section 4.02 is effective only to the extent that such advance is, in the good faith judgment of the Servicer made not later than the second Business Day prior to each Distribution Date, reimbursable from Insurance Proceeds or Liquidation Proceeds of the related Mortgage Loans or recoverable as late Monthly Payments with respect to the related Mortgage Loans or otherwise.

Prior to the close of business on the second Business Day prior to each Distribution Date, the Servicer shall determine whether or not it will make a Monthly P&I Advance not later than the Business Day prior to such Distribution Date and shall furnish a written statement to the Trustee, the Paying Agent, if any, and to any Certificateholder requesting the same, setting forth the aggregate amount to be advanced on account of principal and interest in respect of the Mortgage Loans, stated separately.

In the event that the Servicer shall be required to make a Monthly P&I Advance, it shall, not later than the Business Day prior to the related Distribution Date either (i) deposit in the Custodial Account for P&I an amount equal to such Monthly P&I Advance, (ii) make an appropriate entry in the records of the Custodial Account for P&I that funds in such account being held for future distribution or withdrawal have been, as permitted by this Section 4.02, used by the Servicer to make such Monthly P&I Advance or (iii) make advances in the form of any combination of (i) and (ii) aggregating the amount of such Monthly P&I Advance. Any funds being held for future distribution and so used shall be replaced by the Servicer by deposit in the Custodial Account for P&I not later than the Business Day prior to any future Distribution Date to the extent that funds otherwise available for distribution on such Distribution Date with respect to the Mortgage Loans shall be less than payments required to be made hereunder on such Distribution Date.

(b) Prior to noon New York City time two Business Days prior to each Distribution Date, the Servicer shall provide (x) the Trustee and (y) the Company with a statement in writing of:

Section 4.03. Nonrecoverable Advances. Any advance previously made by the Servicer that the Servicer shall determine in its good faith judgment not to be ultimately recoverable from Insurance Proceeds or Liquidation Proceeds or otherwise with respect to such Mortgage Loan or recoverable as late Monthly Payments with respect to such Mortgage Loan shall be a Nonrecoverable Advance. The determination by the Servicer that it has made a Nonrecoverable Advance or that any advance would constitute a Nonrecoverable Advance shall be evidenced by an Officer’s Certificate of the Servicer delivered to the Trustee on the Determination Date and detailing the reasons for such determination. Notwithstanding any other provision of this Agreement, any insurance policy relating to the Mortgage Loans, or any other agreement relating to the Mortgage Loans to which the Company or the Servicer is a party, (a) the Servicer shall not be obligated to, and shall not, make any advance that, after reasonable inquiry and in its sole discretion, the Servicer shall determine would be a Nonrecoverable Advance and (b) the Servicer shall be entitled to reimbursement for any advance as provided in Section 3.05(a)(i) and (ii) of this Agreement.

Section 4.04. Distributions to Certificateholders; Payment of Special Primary Insurance Premiums.

Furthermore, on each Distribution Date from and including the Distribution Date in January 2006 to and including the Final Yield Maintenance Payment Date for the Class A-3 Certificates, the Trustee shall on behalf of the Trust withdraw from the Certificate Account and distribute to the Holders of such Class the Yield Maintenance Payment Amount for such Class; and on each Distribution Date from and including the Distribution Date in January 2006 to and including the Final Yield Maintenance Payment Date for the Class A-5 Certificates, the Trustee shall withdraw from the Certificate Account and distribute to the Holders of such Class the Yield Maintenance Payment Amount for such Class.

The net distributions to the Certificates pursuant to this Section 4.04(a) shall be made in accordance with the written statement received from the Servicer pursuant to Section 4.02(b) and without any responsibility to recalculate, verify or confirm the information in such statement. Any Special Primary Insurance Premiums distributed pursuant to clause (i) of the first paragraph of this Section 4.04(a) shall be distributed by any method specified in the respective Special Primary Insurance Policy as directed by the related insurer to the Servicer (and by the Servicer to the Trustee). Amounts distributed to the Certificateholders pursuant to clause (ii) of the first paragraph of this Section 4.04(a) shall be distributed by wire transfer in immediately available funds for the account of, or by check mailed to, each such Certificateholder of record on the immediately preceding Record Date (other than as provided in Section 9.01 respecting the final distribution), as specified by each such Certificateholder and at the address of such Holder appearing in the Certificate Register.

(b) All reductions in the Certificate Principal Balance of a Certificate effected by distributions of principal and all allocations of Realized Losses made on any Distribution Date shall be binding upon all Holders of such Certificate and of any Certificate issued upon the registration of transfer or exchange therefor or in lieu thereof, whether or not such distribution is noted on such Certificate. The final distribution of principal of each Certificate (and the final distribution upon the Class R Certificates upon (i) the termination of REMIC I and REMIC II and (ii) the payment, or making provision for payment, of all liabilities of the Trust) shall be payable in the manner provided above only upon presentation and surrender thereof on or after the Distribution Date therefor at the office or agency of the Certificate Registrar specified in the notice delivered pursuant to Section 4.04(c)(ii) and Section 9.01(b).

(c) Whenever, on the basis of Curtailments, Payoffs and Monthly Payments on the Mortgage Loans and Insurance Proceeds and Liquidation Proceeds received and expected to be received during the Payoff Period, the Servicer has notified the Trustee that it believes that the entire remaining unpaid Class Principal Balance of any Class of Certificates will become distributable on the next Distribution Date, the Trustee shall, no later than the 18th day of the month of such Distribution Date, mail or cause to be mailed to each Person in whose name a Certificate to be so retired is registered at the close of business on the Record Date and to the Rating Agencies a notice to the effect that:

(i) it is expected that funds sufficient to make such final distribution will be available in the Certificate Account on such Distribution Date, and

(ii) if such funds are available, (A) such final distribution will be payable on such Distribution Date, but only upon presentation and surrender of such Certificate at the office or agency of the Certificate Registrar maintained for such purpose (the address of which shall be set forth in such notice), and (B) no interest shall accrue on such Certificate after such Distribution Date.

(a) The Certificates shall be substantially in the forms set forth in Exhibit A and B with the additional insertion from Exhibit H attached hereto, and shall be executed by the Trustee on behalf of the Trust, authenticated by the Trustee (or any duly appointed Authenticating Agent) and delivered (i) upon and pursuant to the order of the Company and (ii) upon receipt by the Trustee of the documents specified in Section 2.01. The Certificates shall be issuable in Authorized Denominations. Certificates shall be executed by manual or facsimile signature on behalf of the Trust by authorized officers of the Trustee. Certificates bearing the manual or facsimile signatures of individuals who were at the time of execution the proper officers of the Trustee shall bind the Trust, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Certificates or did not hold such offices at the date of such Certificates. No Certificate shall be entitled to any benefit under this Agreement, or be valid for any purpose, unless there appears on such Certificate a certificate of authentication substantially in the form provided for herein executed by the Trustee or any Authenticating Agent by manual signature, and such certificate upon any Certificate shall be conclusive evidence, and the only evidence, that such Certificate has been duly authenticated and delivered hereunder. All Certificates shall be dated the date of their authentication.

(b) The following definitions apply for purposes of this Section 5.01: “Disqualified Organization” means any Person which is not a Permitted Transferee, but does not include any “Pass-Through Entity” which owns or holds a Residual Certificate and of which a Disqualified Organization, directly or indirectly, may be a stockholder, partner or beneficiary; “Pass-Through Entity” means any regulated investment company, real estate investment trust, common trust fund, partnership, trust or estate, and any organization to which Section 1381 of the Code applies; “Ownership Interest” means, with respect to any Residual Certificate, any ownership or security interest in such Residual Certificate, including any interest in a Residual Certificate as the Holder thereof and any other interest therein whether direct or indirect, legal or beneficial, as owner or as pledgee; “Transfer” means any direct or indirect transfer or sale of, or directly or indirectly transferring or selling any Ownership Interest in a Residual Certificate; and “Transferee” means any Person who is acquiring by Transfer any Ownership Interest in a Residual Certificate.

(c) Restrictions on Transfers of the Residual Certificates to Disqualified Organizations are set forth in this Section 5.01(c).

(i) Each Person who has or who acquires any Ownership Interest in a Residual Certificate shall be deemed by the acceptance or acquisition of such Ownership Interest to have agreed to be bound by the following provisions and to have irrevocably authorized the Trustee or its designee under clause (iii)(A) below to deliver payments to a Person other than such Person and to negotiate the terms of any mandatory sale under clause (iii)(B) below and to execute all instruments of transfer and to do all other things necessary in connection with any such sale. The rights of each Person acquiring any Ownership Interest in a Residual Certificate are expressly subject to the following provisions:

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

(B) In connection with any proposed Transfer of any Ownership Interest in a Residual Certificate to a U.S. Person, the Trustee shall require delivery to it, and shall not register the Transfer of any Residual Certificate until its receipt of (1) an affidavit and agreement (a “Transferee Affidavit and Agreement”) attached hereto as Exhibit J from the proposed Transferee, in form and substance satisfactory to the Company, representing and warranting, among other things, that it is not a Non-U.S. Person, that such transferee is a Permitted Transferee, that it is not acquiring its Ownership Interest in the Residual Certificate that is the subject of the proposed Transfer as a nominee, trustee or agent for any Person who is not a Permitted Transferee, that for so long as it retains its Ownership Interest in a Residual Certificate, it will endeavor to remain a Permitted Transferee, and that it has reviewed the provisions of this Section 5.01(c) and agrees to be bound by them, and (2) a certificate, attached hereto as Exhibit I, from the Holder wishing to transfer the Residual Certificate, in form and substance satisfactory to the Company, representing and warranting, among other things, that no purpose of the proposed Transfer is to allow such Holder to impede the assessment or collection of tax.

(C) Notwithstanding the delivery of a Transferee Affidavit and Agreement by a proposed Transferee under clause (B) above, if the Trustee has actual knowledge that the proposed Transferee is not a Permitted Transferee, no Transfer of an Ownership Interest in a Residual Certificate to such proposed Transferee shall be effected.

(D) Each Person holding or acquiring any Ownership Interest in a Residual Certificate agrees by holding or acquiring such Ownership Interest (i) to require a Transferee Affidavit and Agreement from any other Person to whom such Person attempts to transfer its Ownership Interest and to provide a certificate to the Trustee in the form attached hereto as Exhibit J; (ii) to obtain the express written consent of the Company prior to any transfer of such Ownership Interest, which consent may be withheld in the Company’s sole discretion; and (iii) to provide a certificate to the Trustee in the form attached hereto as Exhibit I.

(ii) The Trustee shall register the Transfer of any Residual Certificate only if it shall have received the Transferee Affidavit and Agreement, a certificate of the Holder requesting such transfer in the form attached hereto as Exhibit J and all of such other documents as shall have been reasonably required by the Trustee as a condition to such registration.

(iii) (A) If any “disqualified organization” (as defined in Section 860E(e)(5) of the Code) shall become a holder of a Residual Certificate, then the last preceding Permitted Transferee shall be restored, to the extent permitted by law, to all rights and obligations as Holder thereof retroactive to the date of registration of such Transfer of such Residual Certificate. If any Non-U.S. Person shall become a holder of a Residual Certificate, then the last preceding holder which is a U.S. Person shall be restored, to the extent permitted by law, to all rights and obligations as Holder thereof retroactive to the date of registration of the Transfer to such Non-U.S. Person of such Residual Certificate. If a transfer of a Residual Certificate is disregarded pursuant to the provisions of Treasury Regulations Section 1.860E-1 or Section 1.860G-3, then the last preceding Permitted Transferee shall be restored, to the extent permitted by law, to all rights and obligations as Holder thereof retroactive to the date of registration of such Transfer of such Residual Certificate. Neither the Trust nor the Trustee shall be under any liability to any Person for any registration of Transfer of a Residual Certificate that is in fact not permitted by this Section 5.01(c) or for making any payments due on such Certificate to the holder thereof or for taking any other action with respect to such holder under the provisions of this Agreement.

(B) If any purported Transferee shall become a Holder of a Residual Certificate in violation of the restrictions in this Section 5.01(c) and to the extent that the retroactive restoration of the rights of the Holder of such Residual Certificate as described in clause (iii)(A) above shall be invalid, illegal or unenforceable, then the Company shall have the right, without notice to the Holder or any prior Holder of such Residual Certificate, to sell such Residual Certificate to a purchaser selected by the Company on such terms as the Company may choose. Such purported Transferee shall promptly endorse and deliver each Residual Certificate in accordance with the instructions of the Company. Such purchaser may be the Company itself or any affiliate of the Company. The proceeds of such sale, net of the commissions (which may include commissions payable to the Company or its affiliates), expenses and taxes due, if any, shall be remitted by the Company to such purported Transferee. The terms and conditions of any sale under this clause (iii)(B) shall be determined in the sole discretion of the Company, and the Company shall not be liable to any Person having an Ownership Interest in a Residual Certificate as a result of its exercise of such discretion.

(iv) The Servicer shall make available, upon written request from the Trustee, all information necessary to compute any tax imposed (A) as a result of the Transfer of an Ownership Interest in a Residual Certificate to any Person who is not a Permitted Transferee, including the information regarding “excess inclusions” of such Residual Certificates required to be provided to the Internal Revenue Service and certain Persons as described in Treasury Regulation Section 1.860D-1(b)(5), and (B) as a result of any regulated investment company, real estate investment trust, common trust fund, partnership, trust, estate or organizations described in Section 1381 of the Code having as among its record holders at any time any Person who is not a Permitted Transferee. Reasonable compensation for providing such information may be required by the Servicer from such Person.

(v) The provisions of this Section 5.01 set forth prior to this Section (v) may be modified, added to or eliminated by the Company, the Servicer and the Trustee, provided that there shall have been delivered to the Trustee the following:

(A) written notification from each of the Rating Agencies to the effect that the modification, addition to or elimination of such provisions will not cause such Rating Agency to downgrade its then-current Ratings of the Certificates; and

(B) an Opinion of Counsel, in form and substance satisfactory to the Company (as evidenced by a certificate of the Company), to the effect that such modification, addition to or absence of such provisions will not cause REMIC I and REMIC II to cease to qualify as a REMIC and will not create a risk that (1) REMIC I and REMIC II may be subject to an entity-level tax caused by the Transfer of any Residual Certificate to a Person which is not a Permitted Transferee or (2) a Certificateholder or another Person will be subject to a REMIC-related tax caused by the Transfer of a Residual Certificate to a Person which is not a Permitted Transferee.

(vi) The following legend shall appear on all Residual Certificates:

ANY RESALE, TRANSFER OR OTHER DISPOSITION OF THIS CERTIFICATE MAY BE MADE ONLY IF THE PROPOSED TRANSFEREE PROVIDES A TRANSFER AFFIDAVIT TO THE COMPANY AND THE TRUSTEE THAT (1) SUCH TRANSFEREE IS NOT EITHER (A) THE UNITED STATES, ANY STATE OR POLITICAL SUBDIVISION THEREOF, ANY FOREIGN GOVERNMENT, ANY INTERNATIONAL ORGANIZATION, OR ANY AGENCY OR INSTRUMENTALITY OF ANY OF THE FOREGOING, (B) ANY ORGANIZATION (OTHER THAN A COOPERATIVE DESCRIBED IN SECTION 521 OF THE CODE) WHICH IS EXEMPT FROM THE TAX IMPOSED BY CHAPTER 1 OF THE CODE UNLESS SUCH ORGANIZATION IS SUBJECT TO THE TAX IMPOSED BY SECTION 511 OF THE CODE, (C) ANY ORGANIZATION DESCRIBED IN SECTION 1381(a)(2)(C) OF THE CODE (ANY SUCH PERSON DESCRIBED IN THE FOREGOING CLAUSES (A), (B), OR (C) BEING HEREINAFTER REFERRED TO AS A “DISQUALIFIED ORGANIZATION”), OR (D) AN AGENT OF A DISQUALIFIED ORGANIZATION AND (2) NO PURPOSE OF SUCH TRANSFER IS TO ENABLE THE TRANSFEROR TO IMPEDE THE ASSESSMENT OR COLLECTION OF TAX. SUCH AFFIDAVIT SHALL INCLUDE CERTAIN REPRESENTATIONS AS TO THE FINANCIAL CONDITION OF THE PROPOSED TRANSFEREE. NOTWITHSTANDING THE REGISTRATION IN THE CERTIFICATE REGISTER OF ANY TRANSFER, SALE OR OTHER DISPOSITION OF THIS CLASS R CERTIFICATE TO A DISQUALIFIED ORGANIZATION OR AN AGENT OF A DISQUALIFIED ORGANIZATION, SUCH REGISTRATION SHALL BE DEEMED TO BE OF NO LEGAL FORCE OR EFFECT WHATSOEVER AND SUCH PERSON SHALL NOT BE DEEMED TO BE A CERTIFICATEHOLDER FOR ANY PURPOSE HEREUNDER, INCLUDING, BUT NOT LIMITED TO, THE RECEIPT OF DISTRIBUTIONS ON THIS CERTIFICATE. EACH HOLDER OF THE CLASS R CERTIFICATE BY ACCEPTANCE OF THIS CERTIFICATE SHALL BE DEEMED TO HAVE CONSENTED TO THE PROVISIONS OF THIS PARAGRAPH.

(vii) The Tax Matters Person for each of REMIC I and REMIC II, while not a Disqualified Organization, shall be the tax matters person for the related REMIC within the meaning of Section 6231(a)(7) of the Code and Treasury Regulation Section 1.860F-4(d).

(d) In the case of any Junior Subordinate Certificate or Class PPP Certificate presented for registration in the name of any Person, the Trustee shall require (i) an officer’s certificate substantially in the form of Exhibit N attached hereto acceptable to and in form and substance satisfactory to the Trustee and the Company, which officer’s certificate shall not be an expense of the Trust, the Trustee, the Delaware Trustee, the Servicer or the Company, and (ii) only if such officer’s certificate indicates that a Benefit Plan Opinion is delivered in connection therewith, a Benefit Plan Opinion.

In the case of any Residual Certificate presented for registration in the name of any Person, the Trustee shall require (i) a Transferee Affidavit and Agreement which includes the representation set forth in paragraph 19 of the form attached hereto as Exhibit J and (ii) only if the representation set forth in such paragraph 19 indicates that a Benefit Plan Opinion is delivered in connection therewith, a Benefit Plan Opinion.

(e) No transfer, sale, pledge or other disposition of a Junior Subordinate Certificate or Class PPP Certificate shall be made unless such transfer, sale, pledge or other disposition is made in accordance with this Section 5.01(e) or Section 5.01(f). Each Person who, at any time, acquires any ownership interest in any Junior Subordinate Certificate or Class PPP Certificate shall be deemed by the acceptance or acquisition of such ownership interest to have agreed to be bound by the following provisions of this Section 5.01(e) and Section 5.01(f), as applicable. No transfer of a Junior Subordinate Certificate or Class PPP Certificate shall be deemed to be made in accordance with this Section 5.01(e) unless such transfer is made pursuant to an effective registration statement under the Securities Act or unless the Trustee is provided with the certificates and an Opinion of Counsel, if required, on which the Trustee may conclusively rely, to the effect that such transfer is exempt from the registration requirements under the Securities Act, as follows. In the event that a transfer is to be made in reliance upon an exemption from the Securities Act, the Trustee shall require, in order to assure compliance with the Securities Act, that the Certificateholder desiring to effect such transfer certify to the Trustee and the Trust in writing, in substantially the form attached hereto as Exhibit F, the facts surrounding the transfer, with such modifications to such Exhibit F as may be appropriate to reflect the actual facts of the proposed transfer, and that the Certificateholder’s proposed transferee certify to the Trustee and the Trust in writing, in substantially the form attached hereto as Exhibit G, the facts surrounding the transfer, with such modifications to such Exhibit G as may be appropriate to reflect the actual facts of the proposed transfer. If such certificate of the proposed transferee does not contain substantially the substance of Exhibit G, the Trustee shall require an Opinion of Counsel that such transfer may be made without registration, which Opinion of Counsel shall not be obtained at the expense of the Trustee, the Delaware Trustee, the Trust, the Servicer or the Company. Such Opinion of Counsel shall allow for the forwarding of, and the Trustee shall forward, a copy thereof to the Rating Agencies. Notwithstanding the foregoing, any Junior Subordinate Certificate or Class PPP Certificate may be transferred, sold, pledged or otherwise disposed of in accordance with the requirements set forth in Section 5.01(f).

(f) To effectuate a transfer of a Junior Subordinate Certificate or Class PPP Certificate in accordance with this Section 5.01(f), the proposed transferee of such Certificate must provide the Trustee and the Company with an investment letter substantially in the form of Exhibit L attached hereto, which investment letter shall not be an expense of the Trust, the Trustee, the Delaware Trustee or the Company, and which investment letter states that, among other things, such transferee (i) is a “qualified institutional buyer” as defined under Rule 144A, acting for its own account or the accounts of other “qualified institutional buyers” as defined under Rule 144A, and (ii) is aware that the proposed transferor intends to rely on the exemption from registration requirements under the Securities Act provided by Rule 144A. Notwithstanding the foregoing, the proposed transferee of such Certificate shall not be required to provide the Trustee or the Company with Annex 1 or Annex 2 to the form of Exhibit L attached hereto if the Company so consents prior to each such transfer. Such transfers shall be deemed to have complied with the requirements of this Section 5.01(f). The Holder of a Certificate desiring to effect such transfer does hereby agree to indemnify the Trust, the Trustee, the Delaware Trustee, the Servicer, the Company, and the Certificate Registrar against any liability that may result if transfer is not made in accordance with this Agreement.

(g) (1) In the case of any ERISA Restricted Certificate presented for registration in the name of any Person, the prospective transferee shall be required to provide the Trustee and the Company (A) an officer’s certificate substantially in the form of Exhibit O attached hereto acceptable to and in form and substance satisfactory to the Trustee and the Company, which officer’s certificate shall not be an expense of the Trust, the Servicer, the Trustee, the Delaware Trustee or the Company, and (B) only if such officer’s certificate indicates that a Benefit Plan Opinion is delivered in connection therewith, a Benefit Plan Opinion.

(2) Notwithstanding the foregoing, a certification (and, if applicable, a Benefit Plan Opinion) as described in Section 5.01(g)(1) above will not be required with respect to the transfer of any ERISA Restricted Certificate to a Clearing Agency, or for any subsequent transfer of any interest in a ERISA Restricted Certificate for so long as such Certificate is a Book-Entry Certificate (each such ERISA Restricted Certificate, a “Book-Entry ERISA Restricted Certificate”). Any transferee of a Book-Entry ERISA Restricted Certificate will be deemed to have represented, by virtue of its acquisition or holding of such Certificate (or interest therein), that either (i) such transferee is not an employee benefit or other plan subject to the prohibited transaction provisions of ERISA or Section 4975 of the Code, or any person (including an investment manager, a named fiduciary or a trustee of any such plan) acting, directly or indirectly, on behalf of or purchasing such Certificate with “plan assets” of any such plan (a “Plan Investor”), (ii) such transferee is an insurance company, the source of funds to be used by it to acquire or hold such Certificate is an “insurance company general account” (within the meaning of Department of Labor Prohibited Transaction Class Exemption (“PTCE”) 95-60), and the conditions in Sections I and III of PTCE 95-60 have been satisfied (each entity that satisfies this clause (ii), a “Complying Insurance Company”) or (iii) such Certificate was rated “BBB-” or better (or its equivalent) by at least one of the Rating Agencies at the time of such transferee’s acquisition of such Certificate (or interest therein).

(3) If any Book-Entry ERISA Restricted Certificate (or any interest therein) is acquired or held in violation of the provisions of Section 5.01(g)(2) above, then the last preceding transferee that either (i) is not a Plan Investor, (ii) is a Complying Insurance Company or (iii) acquired such Certificate at a time when such Certificate was rated “BBB-” or better (or its equivalent) by at least one of the Rating Agencies shall be restored, to the extent permitted by law, to all rights and obligations as Beneficial Holder thereof retroactive to the date of transfer of such Certificate by such preceding transferee. Neither the Trust nor the Trustee shall be under any liability to any Person for making any payments due on such Certificate to such preceding transferee.

(4) Any purported Beneficial Holder whose acquisition or holding of any Book-Entry ERISA Restricted Certificate (or interest therein) was effected in violation of the restrictions in this Section 5.01(g) shall indemnify and hold harmless the Company, the Trustee, the Delaware Trustee, the Servicer, the Trust and each Underwriter from and against any and all liabilities, claims, costs or expenses incurred by such parties as a result of such acquisition or holding.

Section 5.02. Certificates Issuable in Classes; Distributions of Principal and Interest; Authorized Denominations. The aggregate principal amount of the Certificates that may be authenticated and delivered under this Agreement is limited to the aggregate Principal Balance of the Mortgage Loans as of the Cut-Off Date, as specified in the Preliminary Statement to this Agreement, except for Certificates authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, other Certificates pursuant to Section 5.03. Such aggregate principal amount shall be allocated among one or more Classes having designations, types of interests, initial per annum Certificate Interest Rates, initial Class Principal Balances and Final Maturity Dates as specified in the Preliminary Statement to this Agreement. The aggregate Percentage Interest of each Class of Certificates of which the Class Principal Balance equals zero as of the Cut-Off Date that may be authenticated and delivered under this Agreement is limited to 100%. Certificates shall be issued in Authorized Denominations.

Section 5.03. Registration of Transfer and Exchange of Certificates. The Trustee on behalf of the Trust shall cause to be maintained at one of its offices or at its designated agent, a Certificate Register in which there shall be recorded the name and address of each Certificateholder. Subject to such reasonable rules and regulations as the Trustee may prescribe, the Certificate Register shall be amended from time to time by the Trustee or its agent to reflect notice of any changes received by the Trustee or its agent pursuant to Section 10.06. The Trustee hereby appoints itself as the initial Certificate Registrar.

Upon surrender for registration of transfer of any Certificate to the Trustee at the Corporate Trust Office of the Trustee, or such other address or agency as may hereafter be provided to the Servicer in writing by the Trustee, the Trustee on behalf of the Trust shall execute, and the Trustee or any Authenticating Agent shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates of Authorized Denominations. At the option of the Certificateholders, Certificates may be exchanged for other Certificates in Authorized Denominations of like Certificate Principal Balance or Percentage Interest, as applicable, upon surrender of the Certificates to be exchanged at any such office or agency. Whenever any Certificates are so surrendered for exchange, the Trustee on behalf of the Trust shall execute, and the Trustee, or any Authenticating Agent, shall authenticate and deliver, the Certificates which the Certificateholder making the exchange is entitled to receive. Every Certificate presented or surrendered for transfer shall be duly endorsed by, or be accompanied by a written instrument of transfer in form satisfactory to the Trustee or any Authenticating Agent and duly executed by, the Holder thereof or such Xxxxxx’s attorney duly authorized in writing.

A reasonable service charge may be made for any such exchange or transfer of Certificates, and the Trustee may require payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any exchange or transfer of Certificates.

All Certificates surrendered for exchange or transfer shall be cancelled by the Trustee or any Authenticating Agent.

Section 5.04. Mutilated, Destroyed, Lost or Stolen Certificates. If (i) any mutilated Certificate is surrendered to the Trustee or any Authenticating Agent, or (ii) the Trustee or any Authenticating Agent receives evidence to their satisfaction of the destruction, loss or theft of any Certificate, and there is delivered to the Trustee or any Authenticating Agent such security or indemnity as may be required by them to save each of them and the Trust harmless, then, in the absence of notice to the Trustee or any Authenticating Agent that such Certificate has been acquired by a protected purchaser, the Trustee on behalf of the Trust shall execute and the Trustee or any Authenticating Agent shall authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a new Certificate of like Certificate Principal Balance or Percentage Interest as applicable. Upon the issuance of any new Certificate under this Section 5.04, the Trustee or any Authenticating Agent may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee or any Authenticating Agent) connected therewith. Any replacement Certificate issued pursuant to this Section 5.04 shall constitute complete and indefeasible evidence of a beneficial interest in the Trust as if originally issued, whether or not the lost or stolen Certificate shall be found at any time.

Section 5.05. Persons Deemed Owners. The Company, the Servicer, the Trust, the Trustee, the Delaware Trustee and any agent of any of them may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions pursuant to Section 4.01 and Section 4.04 and for all other purposes whatsoever, and none of the Company, the Servicer, the Trust, the Trustee, the Delaware Trustee, the Certificate Registrar or any agent thereof shall be affected by notice to the contrary.

Section 5.06. [Reserved.]

Section 5.07. Book-Entry for Book-Entry Certificates. Notwithstanding the foregoing, the Book-Entry Certificates, upon original issuance, shall be issued in the form of one or more word-processed Certificates of Authorized Denomination representing the Book-Entry Certificates, to be delivered to DTC, the initial Clearing Agency, by, or on behalf of, the Company. The Book-Entry Certificates shall initially be registered on the Certificate Register in the name of Cede & Co., the nominee of DTC, as the initial Clearing Agency, and no Beneficial Holder shall receive a definitive certificate representing such Beneficial Holder’s interest in any Class of Book-Entry Certificate, except as provided above and in Section 5.09. Each Book-Entry Certificate shall bear the following legend:

Unless this Certificate is presented by an authorized representative of The Depository Trust Company, a New York corporation (“DTC”), to the Trust or its agent for registration of transfer, exchange, or payment, and any Certificate issued is registered in the name of Cede & Co. or such other name as is requested by an authorized representative of DTC (and any payment is made to Cede & Co. or to such other entity as is requested by an authorized representative of DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch as the registered owner hereof, Cede & Co., has an interest herein.

Unless and until definitive, fully registered Book-Entry Certificates (the “Definitive Certificates”) have been issued to the Beneficial Holders pursuant to Section 5.09:

(a) the provisions of this Section 5.07 shall be in full force and effect with respect to the Book-Entry Certificates;

(b) the Servicer and the Trustee may deal with the Clearing Agency for all purposes with respect to the Book-Entry Certificates (including the making of distributions on the Book-Entry Certificates) as the sole Certificateholder;

(c) to the extent that the provisions of this Section 5.07 conflict with any other provisions of this Agreement, the provisions of this Section 5.07 shall control; and

(d) the rights of the Beneficial Holders shall be exercised only through the Clearing Agency and the DTC Participants and shall be limited to those established by law and agreements between such Beneficial Holders and the Clearing Agency and/or the DTC Participants. Pursuant to the Depositary Agreement, unless and until Definitive Certificates are issued pursuant to Section 5.09, the initial Clearing Agency will make book-entry transfers among the DTC Participants and receive and transmit distributions of principal and interest on the related Class of Book-Entry Certificates to such DTC Participants.

For purposes of any provision of this Agreement requiring or permitting actions with the consent of, or at the direction of, Holders of Book-Entry Certificates evidencing a specified Percentage Interest, such direction or consent may be given by the Clearing Agency at the direction of Beneficial Holders owning Book-Entry Certificates evidencing the requisite Percentage Interest represented by the Book-Entry Certificates. The Clearing Agency may take conflicting actions with respect to the Book-Entry Certificates to the extent that such actions are taken on behalf of the Beneficial Holders.

Section 5.08. Notices to Clearing Agency. Whenever notice or other communication to the Certificateholders is required under this Agreement, unless and until Definitive Certificates shall have been issued to the related Certificateholders pursuant to Section 5.09, the Trustee shall give all such notices and communications specified herein to be given to Holders of the Book-Entry Certificates to the Clearing Agency which shall give such notices and communications to the related DTC Participants in accordance with its applicable rules, regulations and procedures.

Section 5.09. Definitive Certificates. If (a) the Clearing Agency or the Servicer notifies the Trustee in writing that the Clearing Agency is no longer willing or able to discharge properly its responsibilities under the Depositary Agreement with respect to the Book-Entry Certificates and the Trustee or the Servicer is unable to locate a qualified successor, (b) the Servicer, to the extent permitted by law, advises the Trustee in writing that it elects to terminate the book-entry system with respect to the Book-Entry Certificates through the Clearing Agency or (c) after the occurrence of an Event of Default, Certificateholders holding Book-Entry Certificates evidencing Percentage Interests aggregating not less than 66⅔% of the aggregate Class Principal Balance of such Certificates advise the Trustee and the Clearing Agency through DTC Participants in writing that the continuation of a book-entry system with respect to the Book-Entry Certificates through the Clearing Agency is no longer in the best interests of the Certificateholders with respect to such Certificates, the Trustee shall notify all Certificateholders of Book-Entry Certificates of the occurrence of any such event and of the availability of Definitive Certificates. Upon surrender to the Trustee of the Book-Entry Certificates by the Clearing Agency, accompanied by registration instructions from the Clearing Agency for registration, the Trustee on behalf of the Trust shall execute and the Trustee or any Authenticating Agent shall authenticate and deliver the Definitive Certificates. Neither the Company, the Servicer, the Trust nor the Trustee shall be liable for any delay in delivery of such instructions and may conclusively rely on, and shall be protected in relying on, such instructions. Upon the issuance of Definitive Certificates for all of the Certificates all references herein to obligations imposed upon or to be performed by the Clearing Agency shall be deemed to be imposed upon and performed by the Trustee, to the extent applicable with respect to such Definitive Certificates, and the Trustee shall recognize the Holders of Definitive Certificates as Certificateholders hereunder.

Section 5.10. Office for Transfer of Certificates. The Trustee on behalf of the Trust shall maintain an office or agency where Certificates may be surrendered for registration of transfer or exchange. The Corporate Trust Office is initially designated for said purposes.

Section 5.11. Nature of Certificates. The Certificates shall be personal property giving only the rights specifically set forth therein and in this Agreement. The Certificates shall have no preemptive or similar rights and when issued and delivered to the Holders against payment of the purchase price therefor will be fully paid and nonassessable by the Trust. The Holders of the Certificates, in their capacities as such, shall be entitled to the same limitation of personal liability extended to stockholders of private corporations for profit organized under the General Corporation Law of the State of Delaware. THE RECEIPT AND ACCEPTANCE OF A CERTIFICATE OR ANY INTEREST THEREIN BY OR ON BEHALF OF A HOLDER OR ANY BENEFICIAL OWNER, WITHOUT ANY SIGNATURE OR FURTHER MANIFESTATION OF ASSENT, SHALL CONSTITUTE THE UNCONDITIONAL ACCEPTANCE BY THE HOLDER AND ALL OTHERS HAVING A BENEFICIAL INTEREST IN SUCH CERTIFICATE OF ALL THE TERMS AND PROVISIONS OF THIS AGREEMENT, AND SHALL CONSTITUTE THE AGREEMENT OF THE TRUST, SUCH HOLDER AND SUCH OTHERS THAT THE TERMS AND PROVISIONS OF THIS AGREEMENT SHALL BE BINDING, OPERATIVE AND EFFECTIVE AS BETWEEN THE TRUST AND SUCH HOLDER AND SUCH OTHERS.

ARTICLE VI

The Company and the Servicer

Section 6.01. Liability of the Company and the Servicer. Each of the Company and the Servicer shall be liable in accordance herewith only to the extent of the obligations specifically imposed upon and undertaken by the Company or the Servicer, as applicable, herein.

Section 6.02. Merger or Consolidation of the Company or the Servicer. Any Corporation into which either the Company or the Servicer may be merged or consolidated, or any Corporation resulting from any merger, conversion or consolidation to which either the Company or the Servicer shall be a party, or any Corporation succeeding to the business of either the Company or the Servicer, shall be the successor of the Company or the Servicer, as applicable, 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.

Section 6.03. Limitation on Liability of the Company, the Servicer and Others. Neither the Company nor the Servicer nor any of the directors, officers, employees or agents of the Company or the Servicer shall be under any liability to the Trust, the Holders of the REMIC I Regular Interests or the Certificateholders for any action taken by such Person or for such Person’s refraining from the taking of any action in good faith pursuant to this Agreement, or for errors in judgment; provided, however, that this provision shall not protect the Company, the Servicer or any such Person against any liability which would otherwise be imposed by reason of willful misfeasance, bad faith or gross negligence in the performance of duties or by reason of reckless disregard of duties and obligations hereunder. Each of the Company, the Servicer and any director, officer, employee or agent of the Company or the Servicer, as applicable, may rely in good faith on any document of any kind properly executed and submitted by any Person respecting any matters arising hereunder. Each of the Company, the Servicer and any director, officer, employee or agent of the Company or the Servicer, as applicable, shall be indemnified by the Trust and held harmless against any loss, liability or expense incurred in connection with any legal action relating to this Agreement or the Certificates, other than any loss, liability or expense relating to any Mortgage Loan (other than as otherwise permitted in this Agreement) or incurred by reason of willful misfeasance, bad faith or gross negligence in the performance of duties hereunder or by reason of reckless disregard of obligations and duties hereunder. Neither the Company nor the Servicer shall be under any obligation to appear in, prosecute or defend any legal action which is not incidental to its duties related to the Mortgage Loans in accordance with this Agreement and which in its opinion may involve it in any expense or liability; provided, however, that each of the Company and the Servicer may in its discretion undertake any such action which it may deem necessary or desirable with respect to the Mortgage Loans, this Agreement, the Certificates or the rights and duties of the parties hereto and the interests of the Certificateholders hereunder. In such event, the legal expenses and costs of such action and any liability resulting therefrom shall be expenses, costs and liabilities of the Trust and the Company and the Servicer shall be entitled to be reimbursed, as applicable, therefor out of the Certificate Account, as provided by Section 3.05.

Section 6.04. Neither the Company nor the Servicer May Resign. Neither the Company nor the Servicer shall resign from its respective obligations and duties hereby imposed on it, as applicable, except upon determination by the Company or the Servicer that its respective duties hereunder are no longer permissible under applicable law. Any such determination permitting the resignation of the Company or the Servicer shall be evidenced by an Opinion of Counsel to such effect delivered to the Trustee. No such resignation shall become effective until the Trustee or a successor Servicer shall have assumed the Servicer’s responsibilities and obligations in accordance with Section 7.02 hereof.

The Servicer shall give prompt written notice to the Company of any information received by the Servicer which affects or relates to an ongoing obligation or right of the Company under this Agreement.

Section 6.05. Trustee Access. The Servicer shall afford the Company and the Trustee, upon reasonable notice, during normal business hours access to all records maintained by the Servicer, in respect of the Mortgage Loans and in respect of its rights and obligations hereunder and access to such of its officers as are responsible for such obligations. Upon reasonable request, the Servicer, shall furnish the Company and the Trustee with its most recent financial statements (or, for so long as Washington Mutual Bank is the Servicer, the most recent consolidated financial statements for Washington Mutual Bank appearing in the audited financial statements of Washington Mutual, Inc., or the entity with whose financial statements the financial statements of Washington Mutual Bank are consolidated) and such other information as it possesses, and which it is not prohibited by law or, to the extent applicable, binding obligations to third parties with respect to confidentiality, from disclosing, regarding its business, affairs, property and condition, financial or otherwise.

ARTICLE VII

Default

Section 7.01. Events of Default. (a) In case one or more of the following Events of Default by the Servicer shall occur and be continuing, that is to say:

(i) Any failure by the Servicer to deposit into the Certificate Account any payment required to be deposited therein by the Servicer under the terms of this Agreement which continues unremedied for a period of five 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 Trustee or to the Servicer and the Trustee by the Holders of Certificates evidencing Percentage Interests aggregating not less than 25% of REMIC II; or

(ii) Failure on the part of the Servicer duly to observe or perform in any material respect any other of the covenants or agreements on the part of the Servicer contained in the Certificates or in this Agreement which continues unremedied for a period of 60 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 Trustee, or to the Servicer and the Trustee by the Holders of Certificates evidencing Percentage Interests aggregating not less than 25% of REMIC II; or

(iii) A decree or order of a court or agency or supervisory authority having jurisdiction in the premises for the appointment of a trustee, conservator, receiver or liquidator in any bankruptcy, insolvency, readjustment of debt, 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

(iv) The Servicer shall consent to the appointment of a trustee, conservator, receiver or liquidator in any bankruptcy, 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

(v) 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 bankruptcy, insolvency or reorganization statute, make an assignment for the benefit of its creditors, or voluntarily suspend payment of its obligations; or

(vi) Any failure of the Servicer to make any Monthly P&I Advance (other than a Nonrecoverable Advance) which continues unremedied at the opening of business on the Distribution Date in respect of which such Monthly P&I Advance was to have been made;

then, and in each and every such case, so long as an Event of Default shall not have been remedied, either the Trustee or the Holders of Certificates evidencing Percentage Interests aggregating not less than 25% of REMIC II, by notice in writing to the Company and the Servicer (and to the Trustee if given by the Certificateholders, in which case such notice shall set forth evidence reasonably satisfactory to the Trustee that such Event of Default has occurred and shall not have been remedied) may terminate all of the rights (other than its right to reimbursement for advances) and obligations of the Servicer, including its right to the Servicing Fee, under this Agreement. Such determination shall be final and binding. On or after the receipt by the Servicer of such written notice, all authority and power of the Servicer under this Agreement, whether with respect to the Certificates or the Mortgage Loans or otherwise, shall pass to and be vested in the Trustee pursuant to and under this Section 7.01; and, without limitation, the Trustee is hereby authorized and empowered to execute and deliver, on behalf of the Servicer, as attorney‑in‑fact or otherwise, any and all documents and other instruments, and to do or accomplish all other acts or things necessary or appropriate to effect the purposes of such notice of termination, whether to complete the transfer and endorsement or assignment of the Mortgage Loans and related documents, or otherwise. The Servicer agrees to cooperate with the Trustee in effecting the termination of the Servicer's responsibilities and rights hereunder, including, without limitation, the transfer to the Trustee for administration by it of all cash amounts which shall at the time be credited by the Servicer to the Certificate Account or thereafter be received with respect to the Mortgage Loans.

Notwithstanding the foregoing, if an Event of Default described in clause (vi) of this Section 7.01(a) shall occur, the Trustee shall, by notice in writing to the Servicer, which may be delivered by telecopy, immediately suspend all of the rights and obligations of the Servicer thereafter arising under this Agreement, but without prejudice to any rights it may have as a Certificateholder or to reimbursement of advances, and the Trustee shall act as provided in Section 7.02 to carry out the duties of the Servicer, including the obligation to make any Monthly P&I Advance the nonpayment of which was an Event of Default described in clause (vi) of this Section 7.01(a). Any such action taken by the Trustee must be prior to the distribution on the relevant Distribution Date. If the Servicer shall within two Business Days following such suspension remit to the Trustee the amount of any Monthly P&I Advance (plus interest accrued thereon at a per annum rate equal to the prime rate for United States money center commercial banks as published in The Wall Street Journal) the nonpayment of which by the Servicer was an Event of Default described in clause (vi) of this Section 7.01(a), the Trustee, subject to the last sentence of this paragraph, shall permit the Servicer to resume its rights and obligations as Servicer hereunder. The Servicer agrees that it will reimburse the Trustee for actual, necessary and reasonable costs incurred by the Trustee because of action taken pursuant to clause (vi) of this Section 7.01(a). The Servicer agrees that if an Event of Default as described in clause (vi) of this Section 7.01(a) shall occur more than two times in any twelve month period, the Trustee shall be under no obligation to permit the Servicer to resume its rights and obligations as Servicer hereunder.

(b) In case one or more of the following Events of Default by the Company shall occur and be continuing, that is to say:

(i) Failure on the part of the Company duly to observe or perform in any material respect any of the covenants or agreements on the part of the Company contained in the Certificates or in this Agreement which continues unremedied for a period of 60 days after the date on which written notice of such failure, requiring the same to be remedied, shall have been given to the Company by the Trustee, or to the Company and the Trustee by the Holders of Certificates evidencing Percentage Interests aggregating not less than 25% of REMIC II; or

(ii) A decree or order of a court or agency or supervisory authority having jurisdiction in the premises for the appointment of a trustee, conservator, receiver or liquidator in any bankruptcy, insolvency, readjustment of debt, marshalling of assets and liabilities or similar proceedings, or for the winding‑up or liquidation of its affairs, shall have been entered against the Company and such decree or order shall have remained in force undischarged or unstayed for a period of 60 days; or

(iii) The Company shall consent to the appointment of a trustee, conservator, receiver or liquidator in any bankruptcy, insolvency, readjustment of debt, marshalling of assets and liabilities or similar proceedings of or relating to the Company or of or relating to all or substantially all of its property; or

(iv) The Company shall admit in writing its inability to pay its debts generally as they become due, file a petition to take advantage of any applicable bankruptcy, insolvency or reorganization statute, make an assignment for the benefit of creditors, or voluntarily suspend payment of its obligations;

then, and in each and every such case, so long as such Event of Default shall not have been remedied, the Holders of Certificates evidencing Percentage Interests aggregating not less than 25% of REMIC II, by notice in writing to the Company and the Trustee, may direct the Trustee in accordance with Section 10.03 to institute an action, suit or proceeding in its own name as Trustee hereunder to enforce the Company's obligations hereunder.

(c) In any circumstances in which this Agreement states that Certificateholders owning Certificates evidencing a certain Percentage Interest in REMIC II may take certain action, such action shall be taken by the Trustee, but only if the requisite percentage of Certificateholders required under this Agreement for taking like action or giving like instruction to the Trustee under this Agreement shall have so directed the Trustee in writing.

Section 7.02. Trustee to Act; Appointment of Successor.

(a) On and after the date on which the Servicer receives a notice of termination pursuant to Section 7.01 or the Servicer resigns pursuant to Section 6.04, the Trustee shall be the successor in all respects to the Servicer under this Agreement with respect to the Mortgage Loans in the Mortgage Pool and with respect to the transactions set forth or provided for herein and shall have all the rights and powers and be subject to all the responsibilities, duties and liabilities relating thereto arising on or after such date of termination or resignation placed on the Servicer by the terms and provisions hereof and thereof, and shall have the same limitations on liability herein granted to the Servicer; provided, that the Trustee shall not under any circumstances be responsible for any representations and warranties or any repurchase obligation of the Company or any liability incurred by the Servicer prior to such date of termination or resignation and the Trustee shall not be obligated to make a Monthly P&I Advance if it is prohibited by law from so doing. As compensation therefor, the Trustee shall be entitled to all compensation to which the Servicer would have been entitled if the Servicer had continued to act hereunder. Notwithstanding the above, the Trustee may, if it shall be unwilling to so act, or shall if it is unable to so act, appoint, or petition a court of competent jurisdiction to appoint, any established housing and home finance institution having a net worth of not less than $10,000,000 as the successor to the Servicer hereunder in the assumption of all or any part of the responsibilities, duties or liabilities of the Servicer hereunder. Pending any such appointment, the Trustee is obligated to act in such capacity. In connection with such appointment and assumption, the Trustee 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, together with the compensation to the Trustee, be in excess of that permitted the Servicer hereunder. The Trustee and such successor shall take such actions, consistent with this Agreement, as shall be necessary to effectuate any such succession.

(b) In connection with any termination or resignation of the Servicer hereunder, in the event that any of the Mortgage Loans are MERS Loans, either (i) the successor Servicer (including the Trustee if the Trustee is acting as successor Servicer) shall represent and warrant that it is a member of MERS in good standing and shall agree to comply in all material respects with the rules and procedures of MERS in connection with the servicing of the MERS Loans, in which case the predecessor Servicer shall cooperate with the successor Servicer in registering the transfer of servicing of the MERS Loans to the successor Servicer on the MERS® System in accordance with MERS’ rules and procedures, or (ii) if the successor Servicer is not a member of MERS, the predecessor Servicer shall cooperate with the successor Servicer in (A) de-registering the MERS Loans from the MERS® System and (B) causing MERS to execute and deliver an assignment from MERS to the Trust of the Mortgage securing each MERS Loan in recordable form and in the form otherwise provided under clause (X)(iii) of the definition of “Mortgage File” herein and to execute and deliver such other notices, documents and other instruments as may be necessary or desirable to effect such de-registration and assignment. The predecessor Servicer shall bear any and all fees of MERS and all fees and costs of preparing and recording any assignments of Mortgages as required under this Section 7.02(b).

Section 7.03. Notification to Certificateholders. Upon any such termination or appointment of a successor to the Servicer, the Trustee shall give prompt written notice thereof to the Certificateholders at their respective addresses appearing in the Certificate Register.

Section 8.01. Duties of Trustees.

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

(b) The Trustee, upon receipt of all resolutions, certificates, statements, opinions, reports, documents, orders or other instruments furnished to it which are specifically required to be furnished to it pursuant to any provision of this Agreement, shall examine them to determine whether they are in the form required by this Agreement; provided, however, that the Trustee shall not be responsible for the accuracy or content of any such certificate, statement, opinion, report, or other order or instrument furnished by the Company or Servicer to the Trustee pursuant to this Agreement.

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

(i) Prior to the occurrence of an Event of Default and after the curing of all such Events of Default which may have occurred, the duties and obligations of the Trustee shall be determined solely by the express provisions of this Agreement,

(ii) Neither the Trustee nor the Delaware Trustee shall be liable except for the performance of such duties and obligations as are specifically set forth in this Agreement, no implied covenants or obligations shall be read into this Agreement against the Trustee or the Delaware Trustee, and, in the absence of bad faith on the part of the Trustee or the Delaware Trustee, such trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to such trustee and conforming to the requirements of this Agreement; and

(iii) Neither the Trustee nor the Delaware Trustee shall be personally liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the Certificateholders holding Certificates which evidence Percentage Interests aggregating not less than 25% of REMIC II relating to the time, method and place of conducting any proceeding for any remedy available to such trustee, or relating to the exercise of any trust or power conferred upon such trustee under this Agreement.

(d) Within ten Business Days after the occurrence of any Event of Default known to the Trustee, the Trustee shall transmit by mail to the Rating Agencies notice of each Event of Default. Within 90 days after the occurrence of any Event of Default known to the Trustee, the Trustee shall transmit by mail to all Certificateholders (with a copy to the Rating Agencies) notice of each Event of Default, unless such Event of Default shall have been cured or waived; provided, however, the Trustee shall be protected in withholding such notice if and so long as a Responsible Officer of the Trustee in good faith determines that the withholding of such notice is in the best interests of the Certificateholders; and provided, further, that in the case of any Event of Default of the character specified in Section 7.01(i) or Section 7.01(ii) no such notice to Certificateholders or to the Rating Agencies shall be given until at least 30 days after the occurrence thereof.

(ix) Except as expressly provided in this Agreement, in no event shall the Trustee be under any duty or obligation to monitor, determine, investigate or compel compliance by the Trust with the requirements of the Statutory Trust Statute.

(x) In no event shall the Trustee be obligated or responsible for preparing, executing, filing or delivering in respect of the Trust or another party either (A) any report or filing required by the Securities and Exchange Commission to be prepared, executed, filed or delivered in respect of the Trust or another party or (B) any certification in respect of a report or filing required by the Securities and Exchange Commission.

Section 8.03. Trustees Not Liable for Certificates or Mortgage Loans. The recitals contained herein (other than those relating to the due organization, power and authority of the Trustee and the Delaware Trustee) and in the Certificates (other than the execution of, and certificate of authentication on, the Certificates) shall not be taken as the statements of the Trustee or the Delaware Trustee, and neither the Trustee nor the Delaware Trustee assumes any responsibility for their correctness. Neither the Trustee nor the Delaware Trustee makes any representations as to the validity or sufficiency of this Agreement, the Mortgage Loan Purchase Agreement or of the Certificates or any Mortgage Loan.

Subject to separate written agreements with the Trustee and the Delaware Trustee, the Servicer covenants and agrees to, and the Servicer shall, pay each of the Trustee and the Delaware Trustee from time to time, and such trustee shall be entitled to payment, for all services rendered by it in the execution of the trust hereby created and in the exercise and performance of any of the powers and duties hereunder of such trustee. Except as otherwise expressly provided herein, the Servicer shall pay or reimburse each of the Trustee and the Delaware Trustee upon such trustee’s request for all reasonable expenses and disbursements incurred or made by such trustee in accordance with any of the provisions of this Agreement, including any such expenses incurred or made in connection with a transfer of servicing, and shall indemnify such trustee from any loss, liability or expense incurred by it hereunder (including the reasonable compensation and the expenses and disbursements of its counsel and of all persons not regularly in its employ and any expenses which arise out of or are imposed upon the Trustee or the Delaware Trustee in connection with the creation, operation or termination of the Trust) except any such expense or disbursement as may arise from its own negligence or bad faith. Such obligation shall survive the termination of this Agreement or resignation or removal of the Trustee or the Delaware Trustee. The Servicer shall, at its expense, prepare or cause to be prepared all federal and state income tax and franchise tax and information returns relating to REMIC I or REMIC II required to be prepared or filed by the Trustee or the Delaware Trustee and shall indemnify the Trustee and the Delaware Trustee for any liability of such trustees arising from any error in such returns.

If no successor trustee shall have been so appointed and shall have accepted appointment within 30 days after the giving of such notice of resignation, the resigning trustee may petition any court of competent jurisdiction for the appointment of a successor trustee.

If at any time the Trustee or the Delaware Trustee shall cease to be eligible in accordance with the provisions of Section 8.06 and shall fail to resign after written request therefor by the Servicer, or if at any time the Trustee or the Delaware Trustee shall become incapable of acting, or shall be adjudged bankrupt or insolvent, or a receiver of such trustee or of its property shall be appointed, or any public officer shall take charge or control of such trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, then the Servicer may remove such trustee and appoint a successor trustee by written instrument, in triplicate, copies of which instrument shall be delivered to the trustee so removed, the trustee continuing in its capacity and the successor trustee.

Any expenses associated with the resignation of the Trustee or the Delaware Trustee shall be borne by such trustee, and any expenses associated with the removal of the Trustee or the Delaware Trustee shall be borne by the Servicer.

Section 8.08. Successor Trustee. Any successor trustee appointed as provided in Section 8.07 shall execute, acknowledge and deliver to the Servicer and to its predecessor trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor trustee shall become effective and such successor trustee, without any further act, deed or conveyance, shall become fully vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as Trustee or Delaware Trustee herein. The predecessor shall deliver to the successor trustee all Mortgage Files, related documents, statements and all other property held by it hereunder, and the Servicer and the predecessor trustee shall execute and deliver such instruments and do such other things as may reasonably be required for more fully and certainly vesting and confirming in the successor trustee all such rights, powers, duties and obligations.

Section 8.10. Appointment of Co-Trustee or Separate Trustee. Notwithstanding any other provisions hereof, at any time, for the purpose of meeting any legal requirements of any jurisdiction in which any part of the assets of the Trust may at the time be located, the Servicer and the Trustee or the Delaware Trustee, as applicable, acting jointly shall have the power and shall execute and deliver all instruments to appoint one or more Persons approved by such trustee to act as co-trustee or co-trustees, jointly with such trustee, or separate trustee or separate trustees, of all or any part of the assets of the Trust and to vest in such Person or Persons, in such capacity, such title to the assets of the Trust, or any part thereof, and, subject to the other provisions of this Section 8.10, such powers, duties, obligations, rights and trusts as the Servicer and the Trustee or the Delaware Trustee, as applicable, may consider necessary or desirable; provided, that the Trustee or the Delaware Trustee, as applicable, shall remain liable for all of its obligations and duties under this Agreement. If the Servicer shall not have joined in such appointment within 15 days after the receipt by it of a request so to do, or in case an Event of Default shall have occurred and be continuing, the Trustee or the Delaware Trustee, as applicable, alone shall have the power to make such appointment; provided, that such trustee shall remain liable for all of its obligations and duties under this Agreement. No co-trustee or separate trustee hereunder shall be required to meet the terms of eligibility as a successor trustee under Section 8.06 hereunder and no notice to Certificateholders of the appointment of co-trustee(s) or separate trustee(s) shall be required under Section 8.08 hereof.

In the case of any appointment of a co-trustee or separate trustee pursuant to this Section 8.10, all rights, powers, duties and obligations conferred or imposed upon the Trustee or the Delaware Trustee, as applicable, shall be conferred or imposed upon and exercised or performed by the Trustee or the Delaware Trustee, as applicable, and such separate trustee or co-trustee jointly and severally, except to the extent that under any law of any jurisdiction in which any particular act or acts are to be performed by the Trustee or the Delaware Trustee, as applicable, such trustee shall be incompetent or unqualified to perform such act or acts, in which event such rights, powers, duties and obligations (including the holding of title to the assets of the Trust or any portion thereof in any such jurisdiction) shall be exercised and performed by such separate trustee or co-trustee at the direction of the Trustee or the Delaware Trustee, as applicable.

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

Any separate trustee or co-trustee may, at any time, constitute the Trustee or the Delaware Trustee, as applicable, its agent or attorney-in-fact, with full power and authority, to the extent not prohibited by law, to do any lawful act under or in respect of this Agreement on its behalf and in its name. If any separate trustee or co-trustee shall die, become incapable of acting, resign or be removed, all of its estates, properties, rights, remedies and the trust shall vest in and be exercised by the Trustee or the Delaware Trustee, as applicable, to the extent permitted by law, without the appointment of a new or successor trustee.

Section 8.11. Authenticating Agents. The Trustee may appoint one or more Authenticating Agents which shall be authorized to act on behalf of the Trustee in authenticating Certificates.

Any Paying Agent may at any time resign by giving written notice of resignation to the Trustee and to the Servicer; provided, that the Paying Agent has returned to the Certificate Account or otherwise accounted, to the reasonable satisfaction of the Servicer, for all amounts it has withdrawn from the Certificate Account. The Trustee may, upon prior written approval of the Servicer, at any time terminate the agency of any Paying Agent by giving written notice of termination to such Paying Agent and to the Servicer.

(b) Notice of such purchase, specifying the date upon which the Certificateholders may surrender their Certificates to the Trustee for payment and cancellation, shall be given promptly by letter from the Trustee to Certificateholders mailed not less than 30 days prior to such final distribution, specifying (i) the date upon which final payment of the Certificates will be made upon presentation and surrender of Certificates at the office of the Certificate Registrar therein designated (the “Termination Date”), (ii) the amount of such final payment (the “Termination Payment”) and (iii) that the Record Date otherwise applicable to the Distribution Date upon which the Termination Date occurs is not applicable, payments being made only upon presentation and surrender of the Certificates at the office of the Certificate Registrar therein specified. Upon any such notice, the Certificate Account shall terminate subject to the Servicer’s obligation to hold all amounts payable to Certificateholders in trust without interest pending such payment. The Servicer shall provide the Trustee with written notice of its intent to terminate the Trust upon purchase at least five Business Days, or such lesser time as is acceptable to the Trustee, such acceptance not to be unreasonably withheld, prior to the time that the Trustee is required to mail notice to the Certificateholders.

In the event that all of the Certificateholders shall not surrender their Certificates for cancellation within six months after the Termination Date, the Servicer shall give a second written notice to the remaining Certificateholders to surrender their Certificates for cancellation and receive the Termination Payment with respect thereto. If within one year after the second notice all the Certificates shall not have been surrendered for cancellation, the Servicer may take appropriate steps to contact the remaining Certificateholders concerning surrender of their Certificates, and the cost thereof shall be paid out of the funds and other assets which remain in trust hereunder.

Upon the completion of winding up of the Trust, including the payment or the making reasonable provision for payment of all obligations of the Trust in accordance with Section 3808(e) of the Statutory Trust Statute, the Delaware Trustee shall prepare, the Trustee, the Delaware Trustee and any other trustee hereunder shall sign, and the Delaware Trustee (upon the Trustee’s consent acting at direction of the Servicer) shall file, a certificate of cancellation with the Secretary of State in accordance with Section 3810 of the Statutory Trust Statute, at which time the Trust and this Agreement shall terminate. The Servicer shall act as the liquidator of the Trust and shall be responsible for taking all actions in connection with winding up the Trust, in accordance with the requirements of this Agreement (including this Section 9.01 and Section 9.02) and applicable law.

Section 9.02. Additional Termination Requirements.

(a) In the event the Servicer exercises its purchase option as provided in Section 9.01, REMIC I and REMIC II shall be terminated in accordance with the following additional requirements, unless the Servicer, at its own expense, obtains for the Trustee an Opinion of Counsel to the effect that the failure of REMIC I and REMIC II to comply with the requirements of this Section 9.02 will not (i) result in the imposition of taxes on “prohibited transactions” of REMIC I and REMIC II as described in Section 860F of the Code, or (ii) cause REMIC I or REMIC II to fail to qualify as a REMIC at any time that any Certificates are outstanding:

(i) Within 90 days prior to the final Distribution Date set forth in the notice given by the Trustee under Section 9.01, the Tax Matters Person shall prepare the documentation required and the Tax Matters Person and the Trustee shall adopt a plan of complete liquidation on behalf of REMIC I and REMIC II meeting the requirements of a qualified liquidation under Section 860F of the Code and any regulations thereunder, as evidenced by an Opinion of Counsel obtained at the expense of the Servicer, on behalf of REMIC I and REMIC II; and

(ii) At or after the time of adoption of such a plan of complete liquidation and at or prior to the final Distribution Date, the Servicer on behalf of the Trust shall sell all of the assets of REMIC I and REMIC II to the Servicer for cash in the amount specified in Section 9.01.

(b) By its acceptance of any Residual Certificate, the Holder thereof hereby agrees to authorize the Tax Matters Person and the Trustee to adopt such a plan of complete liquidation upon the written request of the Tax Matters Person and the Trustee and to take such other action in connection therewith as may be reasonably requested by the Tax Matters Person or the Trustee.

Section 9.03. Trust Irrevocable. Except as expressly provided herein, the trust created hereby is irrevocable.

ARTICLE X

Miscellaneous Provisions

Section 10.01. Amendment.

(a) This Agreement may be amended from time to time by the Servicer, the Company and the Trustee, without the consent of any of the Certificateholders:

(i) to cure any ambiguity;

(ii) to correct or supplement any provision herein which may be defective or inconsistent with any other provisions herein;

(iii) to comply with any requirements imposed by the Code or any regulations thereunder;

(iv) to correct the description of any property at any time included in REMIC I or REMIC II, or to assure the conveyance to the Trust of any property included in REMIC I or REMIC II;

(v) pursuant to Section 5.01(c)(v); and

(vi) to add any provision to, or amend any provision in, this Agreement, provided that such amendment or addition does not adversely affect in any material respect the interests of any Certificateholder;

provided, however, that any such amendment which modifies the rights or obligations of the Delaware Trustee hereunder shall require the consent of the Delaware Trustee; provided, further, that any such amendment which modifies the rights of the Class PPP Certificateholders to receive Assigned Prepayment Premiums, including any amendment to Section 3.20, shall require the consent of each Class PPP Certificateholder. No such amendment (other than one entered into pursuant to clause (iii) of the preceding sentence) shall change the powers of the Servicer. Prior to entering into any amendment (other than one entered into pursuant to clause (iii) of the second preceding sentence) without the consent of Certificateholders pursuant to this paragraph, the Trustee shall require an Opinion of Counsel addressed to the Trust and the Trustee to the effect that such amendment is permitted under this Agreement and has no material adverse effect on the interests of the Certificateholders; provided, however, that no such Opinion of Counsel shall be required if the Company obtains a letter from each Rating Agency stating that the amendment would not result in the downgrading or withdrawal of the respective ratings then assigned to the Certificates. Prior to entering into any amendment pursuant to clause (iii) of the third preceding sentence without the consent of Certificateholders pursuant to this paragraph, the Trustee shall require an Opinion of Counsel to the effect that such action is necessary or helpful to comply with the requirements imposed by the Code or any regulations thereunder and shall not cause any REMIC formed under this Agreement to fail to qualify as such under the Code. The cost of any opinion required by this Section 10.01 shall be borne by the party requesting such amendment.

(b) This Agreement may also be amended from time to time by the Servicer, the Company and the Trustee with the consent of the Holders of Certificates evidencing Percentage Interests aggregating not less than 66% of REMIC II, for the purpose of adding any provisions to, or changing in any manner or eliminating any of the provisions of, this Agreement or of modifying in any manner the rights of the Certificateholders; provided, however, that no such amendment shall, without the consent of the Holder of each Certificate affected thereby (i) reduce in any manner the amount of, or delay the timing of, distributions of principal or interest required to be made hereunder or reduce the Certificateholder’s Percentage Interest, the Certificate Interest Rate or the Termination Payment with respect to any of the Certificates, (ii) reduce the percentage of Percentage Interests specified in this Section 10.01 which are required to amend this Agreement, (iii) create or permit the creation of any lien against any part of REMIC I or REMIC II, or (iv) modify any provision in any way which would permit an earlier retirement of the Certificates; provided, further, that any such amendment which modifies the rights or obligations of the Delaware Trustee hereunder shall require the consent of the Delaware Trustee; provided, further, any such amendment which modifies the rights of the Class PPP Certificateholders to receive Assigned Prepayment Premiums, including any amendment to Section 3.20, shall require the consent of each Class PPP Certificateholder.

Promptly after the execution of any such amendment, the Trustee shall furnish written notification of the substance of such amendment to the Delaware Trustee and each Certificateholder. Any failure to provide such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amendment.

It shall not be necessary for the consent of Certificateholders under this Section 10.01 to approve the particular form of any proposed amendment, but it shall be sufficient if such consent shall approve the substance thereof. The manner of obtaining such consents and of evidencing the authorization of the execution thereof by Certificateholders shall be subject to such reasonable regulations as the Trustee may prescribe.

Section 10.02. Recordation of Agreement. To the extent permitted by applicable law, this Agreement is subject to recordation in all appropriate public offices for real property records in all the counties or the comparable jurisdictions in which any Mortgaged Property is situated, and in any other appropriate public recording office or elsewhere, such recordation to be effected by the Company and at its expense on direction by the Trustee, but only upon direction accompanied by an Opinion of Counsel to the effect that such recordation materially and beneficially affects the interests of the Certificateholders.

Section 10.03. Limitation on Rights of Certificateholders. The death or incapacity of any Certificateholder shall not operate to terminate this Agreement or the Trust, nor entitle such Certificateholder’s legal representatives or heirs to claim an accounting or to take any action or proceeding in any court for a partition or winding-up of the Trust, nor otherwise affect the rights, obligations and liabilities of the parties hereto or any of them.

No Certificateholder shall have any right to vote or in any manner otherwise to control the operation and management of the Trust or the obligations of the parties hereto (except as provided in Section 5.09, Section 7.01, Section 8.01, Section 8.02, Section 8.07, Section 10.01 and this Section 10.03), nor shall anything herein set forth, or contained in the terms of the Certificates, be construed so as to constitute the Certificateholders from time to time as partners or members of an association; nor shall any Certificateholder be under any liability to any third person by reason of any action taken by the parties to this Agreement pursuant to any provision hereof.

No Certificateholder shall have any right by virtue or by availing of any provision of this Agreement to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Agreement, unless such Holder previously shall have given to the Trustee a written notice of default and of the continuance thereof, as hereinbefore provided, and unless also the Holders of Certificates evidencing Percentage Interests aggregating not less than 25% of REMIC II shall have made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder and shall have offered to the Trustee such reasonable indemnity as it may require against the costs, expenses and liabilities to be incurred therein or thereby, and the Trustee, for 60 days after its receipt of such notice, request and offer of indemnity, shall have neglected or refused to institute any such action, suit or proceeding. However, the Trustee is under no obligation to exercise any of the extraordinary trusts or powers vested in it by this Agreement or to make any investigation of matters arising hereunder or to institute, conduct or defend any litigation hereunder or in relation hereto at the request, order or direction of any of the Certificateholders unless such Certificateholders have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities which may be incurred therein or thereby. It is understood and intended, and expressly covenanted by each Certificateholder with every other Certificateholder and the Trustee, that no one or more Holders of Certificates shall have any right in any manner whatever by virtue or by availing of any provision of this Agreement to affect, disturb or prejudice the rights of the Holders of any other of such Certificates, or to obtain or seek to obtain priority over or preference to any other such Holder, or to enforce any right under this Agreement, except in the manner herein provided and for the equal, ratable and common benefit of all Certificateholders. For the protection and enforcement of the provisions of this Section 10.03, each and every Certificateholder and the Trustee shall be entitled to such relief as can be given either at law or in equity.

Section 10.04. Access to List of Certificateholders. The Certificate Registrar shall furnish or cause to be furnished to the Trustee within 30 days after receipt of a request by the Trustee in writing, a list, in such form as the Trustee may reasonably require, of the names and addresses of the Certificateholders as of the most recent Record Date for payment of distributions to such Certificateholders.

If three or more Certificateholders (hereinafter referred to as “applicants”) apply in writing to the Trustee, and such application states that the applicants desire to communicate with other Certificateholders with respect to their rights under this Agreement or under the Certificates and is accompanied by a copy of the communication which such applicants propose to transmit, then the Trustee shall, within five Business Days after the receipt of such list from the Certificate Registrar, afford such applicants access during normal business hours to the most recent list of Certificateholders held by the Trustee. If such a list is as of a date more than 90 days prior to the date of receipt of such applicants’ request, the Trustee shall promptly request from the Certificate Registrar a current list as provided above, and shall afford such applicants access to such list promptly upon receipt.

Every Certificateholder, by receiving and holding the same, agrees with the Servicer, the Company, the Trust, the Trustee and the Delaware Trustee that none of the Servicer, the Company, the Trust, the Trustee or the Delaware Trustee shall be held accountable by reason of the disclosure of any such information as to the names and addresses of the Certificateholders hereunder, regardless of the source from which such information was derived.

Section 10.05. Governing Law. This Agreement shall be construed in accordance with the laws of the State of Delaware without giving effect to its conflict of laws provisions and the obligations, rights and remedies of the parties hereunder shall be determined in accordance with such laws without giving effect to conflict of laws provisions.

Section 10.06. Notices. All demands, notices and communications hereunder shall be in writing and shall be deemed to have been duly given if personally delivered at or mailed by registered or certified mail, return receipt requested, or overnight courier to the applicable Notice Address. Notices to the Rating Agencies shall also be deemed to have been duly given if mailed by first class mail, postage prepaid, to the above listed addresses of the Rating Agencies. Any notice required or permitted to be mailed to a Certificateholder shall be given by first class mail, postage prepaid, at the address of such Holder as shown in the Certificate Register. Any notice so mailed within the time prescribed in this Agreement shall be conclusively presumed to have been duly given, whether or not the Certificateholder receives such notice.

Section 10.07. Severability of Provisions. If any one or more of the covenants, agreements, provisions or terms of this Agreement shall be for any reason whatsoever held invalid, then such covenants, agreements, provisions or terms shall be deemed severable from the remaining covenants, agreements, provisions or terms of this Agreement and shall in no way affect the validity or enforceability of the other provisions of this Agreement or of the Certificates or the rights of the Holders thereof.

Section 10.08. Counterpart Signatures. For the purpose of facilitating the recordation of this Agreement as herein provided and for other purposes, this Agreement may be executed simultaneously in any number of counterparts, each of which counterparts shall be deemed to be an original, and such counterparts shall constitute but one and the same instrument.

Section 10.09. Benefits of Agreement. Nothing in this Agreement or in any Certificate, expressed or implied, shall give to any Person, other than the parties hereto and their respective successors hereunder, any separate trustee or co-trustee appointed under Section 8.10 and the Certificateholders, any benefit or any legal or equitable right, remedy or claim under this Agreement.

WASHINGTON MUTUAL MORTGAGE PASS-THROUGH CERTIFICATE

The Certificates do not represent an obligation of, or an interest in, the Company or any of its affiliates and are not insured or guaranteed by any governmental agency. The Certificates are limited in right of payment to certain collections and recoveries respecting the Mortgage Loans, all as more specifically set forth herein and in the Pooling Agreement. In the event funds are advanced with respect to any Mortgage Loan, such advance is reimbursable to the Servicer from the related recoveries on such Mortgage Loan or from amounts received with respect to other Mortgage Loans to the extent that such advance is not otherwise recoverable.

As provided in the Pooling Agreement, withdrawals from the Certificate Account may be made from time to time for purposes other than distributions to Certificateholders, such purposes including reimbursement to the Servicer of advances made, or certain expenses incurred, by it.

As provided in the Pooling Agreement and subject to certain limitations therein set forth, the transfer of this Certificate is registrable in the Certificate Register upon surrender of this Certificate for registration of transfer at the office of the Certificate Registrar or the office maintained by the Trustee in the City and State of New York, duly endorsed by, or accompanied by an assignment in the form below or other written instrument of transfer in form satisfactory to the Trustee or any Authenticating Agent duly executed by, the Holder hereof or such Xxxxxx's attorney duly authorized in writing, and thereupon one or more new Certificates of Authorized Denominations evidencing the same Percentage Interest set forth hereinabove will be issued to the designated transferee or transferees.

The Certificates are issuable only as registered Certificates without coupons in Authorized Denominations specified in the Pooling Agreement. As provided in the Pooling Agreement and subject to certain limitations therein set forth, Certificates are exchangeable for new Certificates of Authorized Denominations of like Certificate Principal Balance or Percentage Interest, as applicable, as requested by the Holder surrendering the same.

A reasonable service charge may be made for any such registration of transfer or exchange, and the Trustee may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

The Company, the Servicer, the Trust, the Trustee, the Delaware Trustee and any agent of any of them may treat the Person in whose name this Certificate is registered as the owner hereof for all purposes, and none of the Company, the Servicer, the Trust, the Trustee, the Delaware Trustee nor any agent thereof shall be affected by notice to the contrary.

The obligations created by the Pooling Agreement and the Trust created thereby shall terminate upon (i) the later of the final payment or other liquidation (including purchase by the Servicer) of the last Mortgage Loan owned by the Trust or the disposition of all property acquired upon foreclosure or deed in lieu of foreclosure of any Mortgage Loan, and (ii) the payment to Certificateholders of all amounts required to be paid to them pursuant to the Pooling Agreement. The Pooling Agreement permits, but does not require, the Servicer to purchase from the Trust all Mortgage Loans at the time subject thereto and all property acquired by the Trust in respect of any Mortgage Loan upon payment to the Certificateholders of the amounts specified in the Pooling Agreement. The exercise of such right will effect early retirement of the Certificates, the Servicer’s right to purchase being subject to the aggregate Principal Balance of the Mortgage Loans at the time of purchase being less than the Clean-Up Call Percentage of the aggregate Principal Balance of the Mortgage Loans as of the Cut-Off Date.

The Seller hereby certifies, represents and warrants to, and covenants with, the Company, the Servicer, the Trustee and the Trust that:

4. The Seller has no actual knowledge that the Purchaser would be unwilling or unable to pay taxes due on its share of the taxable income attributable to the Certificates.

The Purchaser has represented to the Seller that, if the Certificates constitute a noneconomic residual interest, it (i) understands that as holder of a noneconomic residual interest it may incur tax liabilities in excess of any cash flows generated by the interest, and (ii) intends to pay taxes associated with its holding of the Certificates as they become due.

TRANSFEREE AFFIDAVIT AND AGREEMENT FOR CLASS R CERTIFICATES

STATE OF	_________________________	)

COUNTY OF	_________________________	)

[NAME OF OFFICER], being first duly sworn, deposes and says:

1. That he is [Title of Officer] of [Name of Owner] (record or beneficial owner of the Class R Certificate (the “Owner”)), a [savings institution] [corporation] duly organized and existing under the laws of [the State of ] [the United States], on behalf of which he makes this affidavit and agreement.

2. That the Owner (i) is not and will not be a “disqualified organization” as of [date of transfer] within the meaning of Section 860E(e)(5) of the Internal Revenue Code of 1986, as amended (the “Code”) and will endeavor to remain other than a disqualified organization for so long as it retains its ownership interest in the Class R Certificates, and (ii) is acquiring the Class R Certificates for its own account or for the account of another Owner from which it has received an affidavit and agreement in substantially the same form as this affidavit and agreement. (For this purpose, a disqualified organization” means the United States, any state or political subdivision thereof, or any agency or instrumentality of any of the foregoing (other than an instrumentality all of the activities of which are subject to tax and, except for the Federal Home Loan Mortgage Corporation, a majority of whose board of directors is not selected by any such governmental entity), or any foreign government or international organization, or any agency or instrumentality of such foreign government or organization, any rural electric or telephone cooperative, or any organization (other than certain farmers' cooperatives) that is generally exempt from federal income tax unless such organization is subject to the tax on unrelated business taxable income).

3. That the Owner is aware (i) of the tax that would be imposed on transfers of the Class R Certificates after March 31, 1988; (ii) that such tax would be on the transferor, or, if such transfer is through an agent (which person includes a broker, nominee or middle-man) for a disqualified organization, on the agent; (iii) that the person otherwise liable for the tax shall be relieved of liability for the tax if the transferee furnishes to such person an affidavit that the transferee is not a disqualified organization and, at the time of transfer, such person does not have actual knowledge that the affidavit is false; and (iv) that the Class R Certificates may be a “noneconomic residual interest” within the meaning of Treasury regulations promulgated pursuant to the Code and that the transferor of a noneconomic residual interest will remain liable for any taxes due with respect to the income on such residual interest, if a significant purpose of the transfer was to enable the transferor to impede the assessment or collection of tax.

4. That the Owner is aware of the tax imposed on a “pass-through entity” holding the Class R Certificates if at any time during the taxable year of the pass-through entity a disqualified organization is the record holder of an interest in such entity. (For this purpose, a “pass through entity” includes a regulated investment company, a real estate investment trust or common trust fund, a partnership, trust or estate, and certain cooperatives.)

5. That the Owner is aware that the Trustee will not register the Transfer of the Class R Certificates unless the transferee, or the transferees' agent, delivers to it an affidavit and agreement, among other things, in substantially the same form as this affidavit and agreement. The Owner expressly agrees that it will not consummate any such transfer if it knows or believes that any of the representations contained in such affidavit and agreement are false.

6. That the Owner has reviewed the restrictions set forth on the face of the Class R Certificates and the provisions of Section 5.01 of the Pooling Agreement under which the Class R Certificates were issued (in particular, clauses (iii)(A) and (iii)(B) of Section 5.01(c) which authorize the Trustee to deliver payments to a person other than the Owner and negotiate a mandatory sale by the Trustee in the event the Owner holds such Certificates in violation of Section 5.01). The Owner expressly agrees to be bound by and to comply with such restrictions and provisions.

7. That the Owner consents to any additional restrictions or arrangements that shall be deemed necessary upon advice of counsel to constitute a reasonable arrangement to ensure that the Class R Certificates will only be owned, directly or indirectly, by an Owner that is not a disqualified organization.

8. The Owner's Taxpayer Identification Number is .

9. That no purpose of the Owner relating to the purchase of the Class R Certificates by the Owner is or will be to enable the transferor to impede the assessment or collection of tax, and that in making this representation, the Owner warrants that the Owner is familiar with Treasury Regulation 1.860E-1(c) and with the preamble to the adoption of amendments to that regulation as of July 19, 2002, attached hereto as Exhibit 1.

10. That the Owner anticipates that it will, so long as it holds the Class R Certificates, have sufficient assets to pay any taxes owed by the holder of such Certificates, and hereby represents to and for the benefit of the person from whom it acquired the Class R Certificates that the Owner intends to pay taxes associated with holding such Certificates as they become due, fully understanding that it may incur tax liabilities in excess of any cash flows generated by the Class R Certificates. That the Owner has provided financial statements or other financial information requested by the transferor in connection with the transfer of the Class R Certificates to permit the transferor to assess the financial capability of the Owner to pay such taxes.

11. That the Owner has no present knowledge or expectation that it will be unable to pay any United States taxes owed by it so long as any of the Class R Certificates remain outstanding.

12. That the Owner has no present knowledge or expectation that it will become insolvent or subject to a bankruptcy proceeding for so long as any of the Class R Certificates remain outstanding.

13. That the Owner is familiar with Treasury Regulation 1.860E-1(c) and with the preamble to the adoption of amendments to that regulation as of July 19, 2002, attached hereto as Exhibit 1, and that no purpose of the Owner relating to any sale of the Class R Certificates by the Owner will be to impede the assessment or collection of tax.

14. The Owner is a citizen or resident of the United States, a corporation, partnership or other entity treated as a partnership or corporation for U.S. federal income tax purposes created or organized in, or under the laws of, the United States or any state thereof or the District of Columbia, or an estate or trust whose income from sources without the United States is includible in gross income for United States federal income tax purposes regardless of its connection with the conduct of a trade or business within the United States.

15. The Owner hereby agrees that it will not cause income from the Class R Certificates to be attributable to a foreign permanent establishment or fixed base (within the meaning of an applicable income tax treaty) of the Owner or another United States taxpayer.

16. The Owner hereby agrees to cooperate with the Company and to take any action required of it by the Code or Treasury regulations thereunder (whether now or hereafter promulgated) in order to create or maintain the REMIC status of REMIC I and REMIC II (the “REMICs”).

17. The Owner hereby agrees that it will not take any action that could endanger the REMIC status of the REMICs or result in the imposition of tax on the REMICs unless counsel for, or acceptable to, the Company has provided an opinion that such action will not result in the loss of such REMIC status or the imposition of such tax, as applicable.

18. The Owner as transferee of the Class R Certificates has represented to the transferor that, if the Class R Certificates constitute a noneconomic residual interest, the Owner (i) understands that as holder of a noneconomic residual interest it may incur tax liabilities in excess of any cash flows generated by the interest, and (ii) intends to pay taxes associated with its holding of the Class R Certificates as they become due.

19. That the Owner satisfies the condition in the paragraph marked below [mark one paragraph only]:

Background

This document contains final regulations regarding the proposed amendments to 26 CFR part 1 under section 860E of the Internal Revenue Code (Code). The regulations provide the circumstances under which a transferor of a noneconomic REMIC residual interest meeting the investigation and representation requirements may avail itself of the safe harbor by satisfying either the formula test or the asset test.

Final regulations governing REMICs, issued in 1992, contain rules governing the transfer of noneconomic REMIC residual interests. In general, a transfer of a noneconomic residual interest is disregarded for all tax purposes if a significant purpose of the transfer is to enable the transferor to impede the assessment or collection of tax. A purpose to impede the assessment or collection of tax (a wrongful purpose) exists if the transferor, at the time of the transfer, either knew or should have known that the transferee would be unwilling or unable to pay taxes due on its share of the REMIC's taxable income.

Under a safe harbor, the transferor of a REMIC noneconomic residual interest is presumed not to have a wrongful purpose if two requirements are satisfied: (1) the transferor conducts a reasonable investigation of the transferee's financial condition (the investigation requirement); and (2) the transferor secures a representation from the transferee to the effect that the transferee understands the tax obligations associated with holding a residual interest and intends to pay those taxes (the representation requirement).

The IRS and Treasury have been concerned that some transferors of noneconomic residual interests claim they satisfy the safe harbor even in situations where the economics of the transfer clearly indicate the transferee is unwilling or unable to pay the tax associated with holding the interest. For this reason, on February 7, 2000, the IRS published in the Federal Register (65 FR 5807) a notice of proposed rulemaking (REG-100276-97; REG-122450-98) designed to clarify the safe harbor by adding the ``formula test,'' an economic test. The proposed regulation provides that the safe harbor is unavailable unless the present value of the anticipated tax liabilities associated with holding the residual interest does not exceed the sum of: (1) The present value of any consideration given to the transferee to acquire the interest; (2) the present value of the expected future distributions on the interest; and (3) the present value of the anticipated tax savings associated with holding the interest as the REMIC generates losses.

The notice of proposed rulemaking also contained rules for FASITs. Section 1.860H-6(g) of the proposed regulations provides requirements for transfers of FASIT ownership interests and adopts a safe harbor by reference to the safe harbor provisions of the REMIC regulations.

In January 2001, the IRS published Rev. Proc. 2001-12 (2001-3 I.R.B. 335) to set forth an alternative safe harbor that taxpayers could use while the IRS and the Treasury considered comments on the proposed regulations. Under the alternative safe harbor, if a transferor meets the investigation requirement and the representation requirement but the transfer fails to meet the formula test, the transferor may invoke the safe harbor if the transferee meets a two-prong test (the asset test). A transferee generally meets the first prong of this test if, at the time of the transfer, and in each of the two years preceding the year of transfer, the transferee's gross assets exceed $100 million and its net assets exceed $10 million. A transferee generally meets the second prong of this test if it is a domestic, taxable corporation and agrees in writing not to transfer the interest to any person other than another domestic, taxable corporation that also satisfies the requirements of the asset test. A transferor cannot rely on the asset test if the transferor knows, or has reason to know, that the transferee will not comply with its written agreement to limit the restrictions on subsequent transfers of the residual interest.

Rev. Proc. 2001-12 provides that the asset test fails to be satisfied in the case of a transfer or assignment of a noneconomic residual interest to a foreign branch of an otherwise eligible transferee. If such a transfer or assignment were permitted, a corporate taxpayer might seek to claim that the provisions of an applicable income tax treaty would resource excess inclusion income as foreign source income, and that, as a consequence, any U.S. tax liability attributable to the excess inclusion income could be offset by foreign tax credits. Such a claim would impede the assessment or collection of U.S. tax on excess inclusion income, contrary to the congressional purpose of assuring that such income will be taxable in all events. See, e.g., sections 860E(a)(1), (b), (e) and 860G(b) of the Code.

The Treasury and the IRS have learned that certain taxpayers transferring noneconomic residual interests to foreign branches have attempted to rely on the formula test to obtain safe harbor treatment in an effort to impede the assessment or collection of U.S. tax on excess inclusion income. Accordingly, the final regulations provide that if a noneconomic residual interest is transferred to a foreign permanent establishment or fixed base of a U.S. taxpayer, the transfer is not eligible for safe harbor treatment under either the asset test or the formula test. The final regulations also require a transferee to represent that it will not cause income from the noneconomic residual interest to be attributable to a foreign permanent establishment or fixed base.

Section 1.860E-1(c)(8) provides computational rules that a taxpayer may use to qualify for safe harbor status under the formula test. Section 1.860E-1(c)(8)(i) provides that the transferee is presumed to pay tax at a rate equal to the highest rate of tax specified in section 11(b). Some commentators were concerned that this presumed rate of taxation was too high because it does not take into consideration taxpayers subject to the alternative minimum tax rate. In light of the comments received, this provision has been amended in the final regulations to allow certain transferees that compute their taxable income using the alternative minimum tax rate to use the alternative minimum tax rate applicable to corporations.

Additionally, Sec. 1.860E-1(c)(8)(iii) provides that the present values in the formula test are to be computed using a discount rate equal to the applicable Federal short-term rate prescribed by section 1274(d). This is a change from the proposed regulation and Rev. Proc. 2001-12. In those publications the provision stated that “present values are computed using a discount rate equal to the applicable Federal rate prescribed in section 1274(d) compounded semiannually” and that “[a] lower discount rate may be used if the transferee can demonstrate that it regularly borrows, in the course of its trade or business, substantial funds at such lower rate from an unrelated third party.” The IRS and the Treasury Department have learned that, based on this provision, certain taxpayers have been attempting to use unrealistically low or zero interest rates to satisfy the formula test, frustrating the intent of the test. Furthermore, the Treasury Department and the IRS believe that a rule allowing for a rate other than a rate based on an objective index would add unnecessary complexity to the safe harbor. As a result, the rule in the proposed regulations that permits a transferee to use a lower discount rate, if the transferee can demonstrate that it regularly borrows substantial funds at such lower rate, is not included in the final regulations; and the Federal short-term rate has been substituted for the applicable Federal rate. To simplify taxpayers' computations, the final regulations allow use of any of the published short-term rates, provided that the present values are computed with a corresponding period of compounding. With the exception of the provisions relating to transfers to foreign branches, these changes generally have the proposed applicability date of February 4, 2000, but taxpayers may choose to apply the interest rate formula set forth in the proposed regulation and Rev. Proc. 2001-12 for transfers occurring before August 19, 2002.

It is anticipated that when final regulations are adopted with respect to FASITs, Sec. 1.860H-6(g) of the proposed regulations will be adopted in substantially its present form, with the result that the final regulations contained in this document will also govern transfers of FASIT ownership interests with substantially the same applicability date as is contained in this document.

Effect on Other Documents

Rev. Proc. 2001-12 (2001-3 I.R.B. 335) is obsolete for transfers of noneconomic residual interests in REMICs occurring on or after August 19, 2002.

Special Analyses

It is hereby certified that these regulations will not have a significant economic impact on a substantial number of small entities. This certification is based on the fact that it is unlikely that a substantial number of small entities will hold REMIC residual interests. Therefore, a Regulatory Flexibility Analysis under the Regulatory Flexibility Act (5 U.S.C. chapter 6) is not required. It has been determined that this Treasury decision is not a significant regulatory action as defined in Executive Order 12866. Therefore, a regulatory assessment is not required. It also has been determined that sections 553(b) and 553(d) of the Administrative Procedure Act (5 U.S.C. chapter 5) do not apply to these regulations.
