Section 2.04.        Conveyance
of Mortgage Pool 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 Mortgage Pool
Assets. The Trust, as payment of the purchase price of the Mortgage Pool Assets, shall, on the Closing Date, (i) issue the REMIC I Regular Interests and the Class R-1 Residual Interest to the Company and (ii) issue the Class C-PPP Certificates to
the Company or the Company’s designee in Authorized Denominations. The REMIC I Regular Interests, the Class C-PPP Certificates and the Class R-1 Residual Interest shall together be a separate series of beneficial interests in
the assets of the Trust consisting of the Mortgage Pool 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 Mortgage Pool Assets to the Trust by the Company as provided in this Section 2.04 be, and be construed as, an absolute sale of the
Mortgage Pool Assets. 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. However, in the event
that, notwithstanding the intent of the parties, the Mortgage Pool 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 Mortgage Pool Assets, then


(a)        this Agreement shall constitute a security agreement;


(b)        the conveyance provided for in this Section 2.04 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 Mortgage Pool Assets;



(II)       All accounts, chattel paper, deposit accounts, documents, general intangibles, goods, instruments, investment property, letter-of-credit
rights, letters of credit, money, and oil, gas, and other minerals, consisting of, arising from, or relating to, any of the foregoing; and



(III)      All proceeds of the foregoing.


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, in Section 2.12 or in Section 2.15, 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.  Each Custodial Agreement shall, if such
reports are required to be filed with the Commission as an exhibit to a Report on Form 10-K, require the Custodian, (i) if determined by the Servicer to be a party participating in the servicing function within the meaning of Item 1122 of Regulation AB, to deliver to
the Servicer the report on assessment of compliance with applicable servicing criteria and the accounting firm’s attestation report described in Section 3.13(c) and (ii) if determined by the Servicer to meet the criteria in Item 1108(a)(2)(i) through (iii) of
Regulation AB, to deliver to the Servicer the statement of compliance described in Section 3.13(e). 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 or any successor thereto (other than the Trustee); 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 WMB Loan that is a MERS Loan, if any, has been assigned to the Trustee or to the Trust 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.  The Servicer shall not alter the codes referenced in this
paragraph with respect to any WMB Loan that is a 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.



Section 2.06.        REMIC Election for REMIC
I.


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 Seller does not repurchase such Mortgage Loan within 90 days of such date pursuant to Section 3.3 of the Mortgage Loan Purchase Agreement, 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 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 Certificates. 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.  An exception report delivered by the Custodian to the Servicer pursuant to the Custodial Agreement shall be deemed to constitute such notice. 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 not more than one year later than, and not
more than two years before, the weighted average date of maturity of the Reacquired Mortgage Loans; provided, that the cumulative effect of all substitutions shall not cause the weighted average life (at the pricing speed) of any Class of Certificates to increase by
more than the lesser of (x) five years or (y) 50% of its original weighted average life (at the pricing speed), (iii) the weighted average Current Loan-to-Value Ratio of the Substitute Mortgage Loans shall be equal to or less than the weighted average Current
Loan-to-Value Ratio of the Reacquired Mortgage Loans; provided, that no Substitute Mortgage Loan shall have a Current Loan-to-Value Ratio greater than 100%; (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 WMB 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 WMB 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 Certificates.



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 II Assets, including without limitation all rights represented thereby in and to the Mortgage Pool Assets and the proceeds
thereof;



(II)       All accounts, chattel paper, deposit accounts, documents, general intangibles, goods, instruments, investment property, letter-of-credit
rights, letters of credit, money, and oil, gas, and other minerals, consisting of, arising from, or relating to, any of the foregoing; and



(III)      All proceeds of the foregoing.


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 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 REMIC II Regular Interests and 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 REMIC II
Regular Interests 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 II 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 II 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-2 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 Certificates.



Section 2.15.        Conveyance
of REMIC III 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 III Assets.
The Trust, as payment of the purchase price of the REMIC III Assets, shall on the Closing Date issue the REMIC III Regular Interests and the Class R-3 Residual Interest to the Company (or, in the case of the REMIC III Regular Interests that
are Certificates, to the Company or the Company’s designee in Authorized Denominations). Pursuant to Section 3818 of the Statutory Trust Statute, the REMIC II Regular Interests shall not be cancelled and shall be held as treasury
interests owned by the Trust. The REMIC III Regular Interests and the Class R-3 Residual Interest shall together be a separate series of beneficial interests in the assets of the Trust consisting of the REMIC III 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 III Assets to the Trust by the Company as provided in this Section 2.15 be, and be construed as, an absolute sale of the REMIC III Assets. It is, further, not the intention of the parties that such conveyance be deemed the grant of a security interest in the
REMIC III 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 III 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 III Assets, 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 REMIC III Assets, including without limitation all rights represented thereby in and to the Mortgage Pool Assets and the proceeds
thereof;



(II)       All accounts, chattel paper, deposit accounts, documents, general intangibles, goods, instruments, investment property, letter-of-credit
rights, letters of credit, money, and oil, gas, and other minerals, consisting of, arising from, or relating to, any of the foregoing; and



(III)      All proceeds of the foregoing.


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 REMIC III 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.

III.

in the Form 1066 and any appropriate state return to be filed on behalf of REMIC III for its first taxable year.


The Closing Date is hereby designated as the “startup day” of REMIC III 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 III are hereby designated as “regular interests” in REMIC III for purposes of
Section 860G(a)(1) of the Code. The Class R-3 Residual Interest is hereby designated as the sole class of “residual interest” in REMIC III for purposes of Section 860G(a)(2) of the Code.

and shall hold any documents constituting a part of the REMIC III Assets, and the REMIC III Assets, as Trustee in trust, upon the trust herein set forth, for the use and benefit of all present and future Holders of the Certificates.



Section 2.18.        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 2.19.        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 2007-05, 72 Fed. Reg. 13130 (March 20, 2007)), issued under

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.).



ARTICLE III



Administration and Servicing of Mortgage Loans



Section 3.01.        The
Servicer and GreenPoint.  The Servicer shall act as servicer to service and administer the WMB Loans on behalf of the Trust in accordance with the terms hereof, and Notwithstanding any other provision of the GreenPoint Agreement, GreenPoint shall
act as servicer to service and administer the GreenPoint Loans on behalf of the Trust in accordance with the terms hereof, in each case, 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. Each of the Servicer and GreenPoint may perform its servicing responsibilities through subservicers or other agents or independent contractors, but shall not thereby be released from any of its responsibilities hereunder, and
each of the Servicer and GreenPoint shall diligently pursue all of its rights against such subservicers or other agents or independent contractors; provided, however, that the Servicer shall, if such reports are required to be filed with the Commission as an
exhibit to a Report on Form 10-K, (i) cause each such party, if determined by the Servicer to be a party participating in the servicing function within the meaning of Item 1122 of Regulation AB, to deliver to the Servicer the report on assessment of compliance with
applicable servicing criteria and the accounting firm’s attestation report described in Section 3.13(c) and (ii) cause each such party, if determined by the Servicer to meet the criteria in Item 1108(a)(2)(i) through (iii) of Regulation AB, to deliver to the
Servicer the statement of compliance described in Section 3.13(e); provided, further, that GreenPoint shall comply with the requirements under Section 8.7 of the GreenPoint Regulation AB Addendum.


Each of the Servicer and GreenPoint shall make reasonable efforts to collect or cause to be collected all payments called for under the terms and provisions of the Serviced 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 Serviced Loans and held in portfolios of responsible mortgage lenders in the local areas where each related Mortgaged Property is located. Each of the Servicer and GreenPoint shall enforce
“due-on-sale” clauses with respect to the related Serviced Loans, to the extent permitted by law, subject to the provisions set forth in Section 3.08.


Consistent with the foregoing, each of the Servicer and GreenPoint 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 Serviced Loan and (ii) only upon determining that the coverage of any applicable insurance policy or guaranty related to a Serviced 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 related to a Serviced Loan or for the liquidation of delinquent items.


Consistent with the terms of this Section 3.01, each of the Servicer and GreenPoint may waive, modify or vary any term of any Serviced 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 such Serviced Loan, that the security for, and the timely and full collectability of, such
Serviced 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 Serviced Loan or in the reasonable judgment of the Servicer or GreenPoint,
as applicable, such default is imminent) neither the Servicer nor GreenPoint shall permit any modification with respect to any Serviced 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 Serviced 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, neither the Servicer nor G shall permit any modification with respect to any Serviced Loan that would both constitute a sale or exchange of such Serviced 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 Serviced Loan that is treated as a Principal Prepayment or in a default situation)
and cause any REMIC formed under this Agreement to fail to qualify as such under the Code. Each of the Servicer and GreenPoint 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 Serviced
Loan, that the security for, and the timely and full collectability of, such Serviced Loan would not be adversely affected thereby and that no REMIC formed under this Agreement would fail to continue to qualify as a REMIC 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 formed under this Agreement as a result thereof.


Each of the Servicer and GreenPoint 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 Certificates, 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 Serviced Loans and with respect to the related Mortgaged Properties. Each of the Servicer and GreenPoint 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 Certificates, the Trustee and the Trust, or any of them, such instruments of assignment or other comparable instruments as the
Servicer or GreenPoint, as applicable, shall, in its sole judgment, deem appropriate in order to register any Serviced Loan on the MERS® System or to cause the removal of any Serviced Loan from registration thereon. Any expenses incurred in connection with the
actions described in the preceding sentence shall be borne by the Servicer or GreenPoint, as applicable, 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 or GreenPoint.  The Trustee on behalf of the Trust shall execute and furnish to the Servicer or GreenPoint, at the Servicer’s or GreenPoint’s direction, any powers of attorney and other documents prepared by the Servicer
or GreenPoint and determined by the Servicer of GreenPoint to be necessary or appropriate to enable the Servicer or GreenPoint to carry out its supervisory, servicing and administrative duties under this Agreement.


Each of the Servicer and GreenPoint shall obtain (to the extent generally commercially available) and maintain fidelity bond and errors and omissions coverage acceptable to Fannie Mae or Freddie Mac with
respect to its obligations under this Agreement.  Each of the Servicer and GreenPoint shall establish escrow accounts for, or pay when due (by means of an advance), any tax liens in connection with the Mortgaged Properties related to the Serviced Loans and
premiums with respect to any insurance required to be maintained by the Servicer or GreenPoint, as applicable, 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 WMB Nonrecoverable Advance or a GreenPoint Nonrecoverable Advance when made.


In connection with the servicing and administering of each WMB Loan, each of the Servicer and GreenPoint and any affiliate thereof (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 and Buydown Fund Accounts; GreenPoint Monthly P&I Advances; GreenPoint Nonrecoverable Advances.



            (a)        The Servicer shall
establish and maintain the WMB 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 WMB Loans (or, in the case of clause (v) or
(vi)(c) below, with respect to all of the Mortgage Loans):



(i)         all scheduled payments of principal;



(ii)        all scheduled payments of interest, net of the WMB Servicing Fees (to the extent not applied to
pay WMB 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 WMB Loans, (b) all payments made by the Servicer in
respect of Prepayment Premiums on WMB Loans pursuant to Section 3.20(c) and (c) all payments received by the Servicer from the Seller in respect of Prepayment Premiums on Mortgage Loans 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 WMB Custodial Accounts for P&I the additional servicing compensation described in the second sentence of the definition of
“WMB Servicing Fee.”


In the event that Buydown Funds have been provided with respect to any WMB 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 WMB Custodial Accounts for P&I and the Buydown Fund Accounts for the purposes required or permitted by this
Agreement.


The aggregate amount deposited in a WMB Custodial Account for P&I on any date pursuant to this Section 3.02 may be net of any amounts permitted to be withdrawn by the Servicer from such account on such
date pursuant to Section 3.05.


The Servicer hereby undertakes to assure remittance to the Certificate Account of all amounts (i) relating to the WMB Loans that have been collected by the Servicer or (ii) relating to the GreenPoint Loans
that have been deposited by GreenPoint in the Investment Account, and are due to the Certificate Account pursuant to Section 3.04 of this Agreement.


Funds held in the WMB 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 investments as shall be required to maintain the Ratings.



            (b)        GreenPoint shall establish
and maintain the GreenPoint Custodial Account and shall deposit or cause to be deposited therein on a daily basis the following amounts received or advanced by GreenPoint with respect to the GreenPoint Loans:



(i)         all scheduled payments of principal;



(ii)        all scheduled payments of interest, net of the GreenPoint Servicing Fee;



(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 GreenPoint in an escrow account established for such purpose and maintained in an Eligible Institution, and which may, at GreenPoint’s option, be invested in Eligible Investments), Liquidation Proceeds, Excess
Liquidation Proceeds and Subsequent Recoveries;



(v)        (a) all Prepayment Charges collected on the GreenPoint Loans and (b) all payments made by
GreenPoint in respect of Prepayment Charges on GreenPoint Loans pursuant to Section 3.21(c);



(vi)       all GreenPoint Monthly P&I Advances; and



(vii)      all GreenPoint Compensating Interest.


GreenPoint shall not be required to deposit or cause to be deposited in the GreenPoint Custodial Accounts the additional servicing compensation described in the second sentence of the definition of
“GreenPoint Servicing Fee.”


GreenPoint is hereby authorized to make withdrawals from and to issue drafts against the GreenPoint Custodial Accounts for the purposes required or permitted by this Agreement.


Funds held in the GreenPoint Custodial Account may, at GreenPoint’s option, for its own account and at its own risk, be invested in one or more Eligible Investments which shall in no event mature
later than the Business Day immediately preceding the next GreenPoint Monthly Remittance Date following the date such funds are invested. GreenPoint shall bear any and all losses incurred on any investments made with funds on deposit in the GreenPoint Custodial
Account and shall be paid all gains realized on such investments as additional servicing compensation.


(c)        Prior to the close of business on the Business Day immediately preceding each GreenPoint Monthly Remittance Date, GreenPoint shall deposit in the GreenPoint
Custodial Account an amount equal to any shortfall between (i) Monthly Payments (net of the GreenPoint Servicing Fee) scheduled to be received in respect of the GreenPoint Loans on the immediately preceding Due Date and (ii) the amounts actually received as of the
close of business on the immediately preceding GreenPoint Determination Date (the aggregate of such amounts, the “GreenPoint Monthly P&I Advance”); provided, however, that with respect to any GreenPoint Loan that is a Balloon Loan that
is delinquent on its maturity date, GreenPoint will not be required to advance the related balloon payment but will be required to continue to make advances in accordance with this Section 3.02(c) with respect to such Balloon Loan in an amount equal to one
month’s interest on the unpaid principal balance at the applicable Pass-Through Rate for each Distribution Date to the extent GreenPoint deems such amount to be recoverable.  GreenPoint’s obligation to make any advance described in this Section
3.02(c) is effective only to the extent that such advance is, in the good faith judgment of GreenPoint made not later than the second Business Day prior to each GreenPoint Monthly Remittance Date, reimbursable from Insurance Proceeds or Liquidation Proceeds of the
related GreenPoint Loan or recoverable as late Monthly Payments with respect to the related GreenPoint Loan or otherwise.


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



Section 3.03.        The
Investment Account; Eligible Investments.


(a)        At its option, the Servicer may invest funds withdrawn from the WMB 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 for
investment only as set forth in this Section 3.03. At its option, the Servicer may also invest, as set forth in this Section 3.03, amounts deposited by GreenPoint in the Investment Account 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. The Servicer shall bear any and all losses incurred on any investments made with funds on deposit in the Investment Account and shall be paid all gains realized on such investments (except Payoff Earnings
on WMB Loans 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 investments as shall be required to maintain the Ratings.


(c)        On each GreenPoint Monthly Remittance Date, GreenPoint shall withdraw from the GreenPoint Custodial Account and deposit in the Investment Account all amounts
credited to the GreenPoint Custodial Account as of the close of business on the preceding GreenPoint Custodial Determination Date, net of charges against or withdrawals from the GreenPoint Custodial Account pursuant to Section 3.5(d), plus all GreenPoint Monthly
P&I Advances deposited in the GreenPoint Custodial Account prior to such GreenPoint Monthly Remittance Date pursuant to Section 3.2(b), minus (i) any amounts attributable to Payoffs or Curtailments on GreenPoint Loans received after the last day of the Prior
Period immediately preceding such GreenPoint Monthly Remittance Date and (ii) any Monthly Payments on GreenPoint Loans collected but due on a Due Date subsequent to such GreenPoint Monthly Remittance Date.



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 WMB 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 WMB Custodial Accounts for P&I pursuant to Section 3.05(a)(i) through (v)):



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



(ii)                Payoffs
on WMB Loans 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 and Subsequent Recoveries with respect to WMB Loans, and Repurchase Proceeds with respect to any
Mortgage Loans, received by the Servicer during the Prior Period;



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



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



(vi)              amounts deposited in
the Investment Account by GreenPoint on the immediately preceding GreenPoint Monthly Remittance Date pursuant to Section 3.03(c) (other than any prepayment penalties received on GreenPoint Loans that are not Prepayment Premiums, and other than any other amounts
deposited in the Investment Account by GreenPoint but not required to be distributed from the Certificate Account on such Distribution Date pursuant to Article IV);



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



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


(c)        On each applicable Distribution Date, the Trustee shall deposit in the Certificate Account the following amounts:



(i)         amounts withdrawn from the Class C-PPP Reserve Fund, in accordance with
Section 3.17.


(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
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 WMB 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) WMB 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 WMB 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 WMB Nonrecoverable Advances, such right to reimbursement pursuant to this paragraph (ii) being limited to amounts received on any WMB Loan;



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



(iv)              To pay to itself the
amount of any investment earnings deposited or earned in the WMB Custodial Accounts for P&I, the Investment Account or the Certificate Account (reduced by the lesser of Payoff Earnings and WMB 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 4.05(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 and after the withdrawals described in Article IV have been made by the
Trustee



(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 WMB Loan, the Servicer shall keep
and maintain, separate accounting for each WMB 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 WMB 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 WMB 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 WMB 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 WMB Nonrecoverable Advances or GreenPoint Nonrecoverable Advances, as applicable.


(d)        GreenPoint is authorized to make withdrawals, from time to time, from the GreenPoint Custodial Account of amounts deposited therein, as
follows:



(i)                  To reimburse itself for the following amounts advanced
by GreenPoint,
to the extent that such amounts have not been previously reimbursed or otherwise recovered by GreenPoint:  (a) GreenPoint Monthly P&I Advances made pursuant to Section 3.02(c), (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 GreenPoint 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 GreenPoint Loan with respect to which such advances were
made;



(ii)                To
reimburse itself for amounts 
advanced by GreenPoint that GreenPoint has determined to
be GreenPoint Nonrecoverable Advances, such right to reimbursement pursuant to this paragraph (ii) being limited to amounts received on any GreenPoint Loan;



(iii)               To pay to
itself the GreenPoint Servicing Fees for the related period (to the extent not already retained by GreenPoint);



(iv)              To pay to itself the
amount of any investment earnings deposited or earned in the GreenPoint Custodial Account;



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



(vi)              To make any deposit
of withdrawn funds to the Investment Account.


GreenPoint shall keep and maintain, separate accounting for each GreenPoint Loan, for the purpose of justifying any withdrawals pursuant to Section 3.05(d)(i) or (ii).



Section 3.06.        Maintenance of Primary Insurance Policies; Collections Thereunder. Each of the Servicer and GreenPoint 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 Serviced 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, neither the Servicer
nor GreenPoint shall have any obligation to maintain any Primary Insurance Policy for a Serviced 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, neither the Servicer nor GreenPoint shall cancel or refuse to renew any Primary Insurance Policy with respect to a Serviced Loan in effect at the date of the initial
issuance of the Certificates that is required to be kept in force hereunder; provided, however, that (i) neither the Servicer nor GreenPoint shall advance funds for the payment of any premium due under any such Primary Insurance Policy
(other than a Special Primary Insurance Policy) if it shall determine that such an advance would be a WMB Nonrecoverable Advance or GreenPoint Nonrecoverable Advance, as applicable, and (ii) the Servicer shall not advance funds for the payment of any premium due
under any Special Primary Insurance Policy.



Section 3.07.        Maintenance of Hazard Insurance. Each of the Servicer and GreenPoint shall cause to be maintained for each Serviced Loan (other than a Cooperative Loan) hazard insurance with extended coverage in an amount that is at least equal to the lesser of
(i) the unpaid principal balance (or, if less, the original principal balance) of such Mortgage Loan and (ii) the amount necessary to fully compensate for any damage or loss to the improvements on the Mortgaged Property on a replacement cost basis, but in either case
not less than the amount necessary to avoid the application of any co-insurance clause contained in the hazard insurance policy. Each of the Servicer and GreenPoint 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 Serviced 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 WMB Custodial Account for P&I or GreenPoint Custodial Account, as applicable, 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 or GreenPoint, as applicable, pursuant to Section 3.05. Such insurance shall be with insurers approved by the Servicer or GreenPoint, as applicable, or by Fannie Mae or Freddie Mac. Other additional insurance may be required
of a Mortgagor related to a Serviced Loan 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 related to a Serviced Loan (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 such Serviced Loan, the Servicer or
GreenPoint, as applicable, 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.  Each of the Servicer
and GreenPoint 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 Serviced 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 related to a Serviced Loan is about to be conveyed by the Mortgagor, the Servicer or GreenPoint, as applicable, 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 Serviced 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 or GreenPoint, as applicable, shall not exercise any such right if the due-on-sale clause, in the reasonable belief of the Servicer or
GreenPoint, 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 or GreenPoint is prohibited from exercising such right,
the Servicer or GreenPoint, as applicable, 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 Serviced Loan shall continue to be covered
(if so covered before the Servicer or GreenPoint enters such agreement) by any related Primary Insurance Policy. Each of the Servicer and GreenPoint 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.  Neither the Servicer nor GreenPoint shall enter into any substitution or assumption with respect to a Serviced Loan if such
substitution or assumption shall (i) both constitute a “significant modification” effecting an exchange or reissuance of such Serviced Loan under the Code (or Treasury regulations promulgated thereunder) and cause any REMIC formed under this Agreement 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.  Each of the Servicer and GreenPoint 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 or GreenPoint for entering into an assumption or substitution of liability agreement shall
be paid to the Servicer or GreenPoint as additional servicing compensation.


Notwithstanding the foregoing paragraph or any other provision of this Agreement, neither the Servicer nor GreenPoint shall be deemed to be in default, breach or otherwise in violation of any of its
obligations hereunder by reason of any assumption of a Serviced Loan by operation of law or any assumption which the Servicer or GreenPoint may be restricted by law from preventing, for any reason whatsoever.



Section 3.09.        Realization Upon Defaulted Mortgage Loans.



            (a)        Each of the Servicer and
GreenPoint shall foreclose upon or otherwise comparably convert, or cause to be foreclosed upon or comparably converted, the ownership of any Mortgaged Property securing a Serviced 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, each of the
Servicer and GreenPoint may, to the extent consistent with prudent mortgage loan servicing practices, accept a payment of less than the outstanding Principal Balance of a delinquent Serviced 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. Neither the Servicer nor GreenPoint shall foreclose upon or otherwise comparably convert a Mortgaged Property if the Servicer or GreenPoint is aware of evidence of toxic waste,
other hazardous substances or other evidence of environmental contamination thereon and the Servicer or GreenPoint, as applicable, determines that it would be imprudent to do so. In connection with such foreclosure or other conversion, each of the Servicer and
GreenPoint 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. Each of the Servicer and GreenPoint 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 Serviced 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, neither the Servicer nor GreenPoint shall advance
funds towards the restoration of the property unless it shall have determined, in its sole judgment, (i) that such restoration will increase the proceeds of liquidation of the Serviced Loan to Certificateholders after reimbursement to itself for such expenses, and
(ii) that such expenses will be recoverable to it through Liquidation Proceeds. Each of the Servicer and GreenPoint shall maintain information required for tax reporting purposes regarding any Mortgaged Property related to a Serviced Loan which is abandoned or which
has been foreclosed or otherwise comparably converted. Each of the Servicer and GreenPoint shall report such information to the Internal Revenue Service and the Mortgagor in the manner required by applicable law.



(b)        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 WMB 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 WMB Loans from the Trust immediately prior to the commencement of foreclosure proceedings at a price equal to the aggregate outstanding Principal Balance of such WMB Loans plus accrued interest thereon at the applicable Mortgage Interest Rate
through the last day of the month in which such WMB 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 WMB Loans so long as (i) the Servicer
has the right to transfer the servicing rights and obligations of such WMB Loans to another servicer and (ii) such Lowest Class B Owner will service such WMB 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.


(c)        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 or GreenPoint, as
applicable, 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 REMIC I unless the Servicer or
GreenPoint, as applicable, 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 or GreenPoint, as applicable, 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 or GreenPoint, as applicable, shall either itself or through an agent selected by the Servicer or GreenPoint, as applicable, 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 or GreenPoint, as applicable, deems to be in the best interest of the Trust for the period prior to the sale of
such property. Additionally, the Servicer or GreenPoint, as applicable, 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 related to a Serviced Loan 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.


(d)        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, REMIC III 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 payment at scheduled maturity of any Mortgage Loan, the Servicer or GreenPoint, as applicable, shall cause such final payment to be deposited in the WMB Custodial Account for P&I or the
GreenPoint Custodial Account, as applicable.  The Servicer or GreenPoint, as applicable, 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 or GreenPoint. With any such Payoff or other final payment, the Servicer or GreenPoint, as applicable, 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 or GreenPoint, as applicable, 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 or GreenPoint by the Trustee or from the Certificate Account, the Investment Account, the related WMB Custodial Account for P&I or the related GreenPoint
Custodial Account. 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 or GreenPoint, as applicable, 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 or GreenPoint and shall execute such documents as shall be necessary to the prosecution of any such proceedings. Such trust receipt shall obligate the Servicer or GreenPoint, as applicable, to return the Mortgage File to the
Trustee (or, if applicable, the Custodian) when the need therefor by the Servicer or GreenPoint 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 or GreenPoint, as applicable,.



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 WMB Loan or GreenPoint Loan that is not a Prepayment Premium, any payment made by GreenPoint in respect of Prepayment Charges (other than Prepayment Charges that
are Prepayment Premiums) on GreenPoint Loans pursuant to Section 3.21(c), and any late charges, nonsufficient funds fees and other fees and charges collected on the WMB Loans, (ii) to the extent provided in Section 3.02(a) or Section 3.03, all gains realized on
investments of funds held in the WMB Custodial Account for P&I or 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.        Compensation to GreenPoint. As compensation for its activities hereunder, GreenPoint shall be entitled to retain from collections of interest on the GreenPoint Loans the GreenPoint Servicing Fees (or, in accordance with
Section 3.05(d)(iii), to withdraw such amounts from the GreenPoint Custodial Account if deposited therein). In addition, GreenPoint shall be entitled to be paid, as additional servicing compensation, (i) any late charges, nonsufficient funds fees and other fees and
charges collected on the GreenPoint Loans (other than any Prepayment Charge received on a GreenPoint Loan) and (ii) to the extent provided in Section 3.02(b), all gains realized on investments of funds held in the GreenPoint Custodial Account. GreenPoint 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 3.13.        Reports on
Assessment of Compliance with Servicing Criteria and Servicing Compliance Statements. The Servicer shall, on or before the 90th day following each December 31 after the Cut-Off Date, deliver to the Company and the Trustee, and, if required, file with
the Commission as an exhibit to a Report on Form 10-K filed on behalf of the Trust, the following documents:



(a)        a report on its assessment of compliance during the preceding calendar year with all applicable servicing criteria set forth in Item
1122(d) of Regulation AB with respect to asset-backed securities transactions taken as a whole involving the Servicer that are backed by assets of the same type as the Mortgage Loans, as required by Item 1122 of Regulation AB;



(b)        with respect to the assessment report described in clause (a) above, a report by a registered public accounting firm that attests to,

(c)        with respect to each subservicer or other agent or independent contractor through which the Servicer performs any of its servicing
responsibilities hereunder and each Custodian, in each case, if determined by the Servicer to be a party participating in the servicing function within the meaning of Item 1122 of Regulation AB, (i) a report prepared by such party on its assessment of compliance
during the preceding calendar year with all applicable servicing criteria set forth in Item 1122(d) of Regulation AB with respect to asset-backed securities transactions taken as a whole involving such party that are backed by assets of the same type as the Mortgage
Loans and (ii) a report by a registered public accounting firm that attests to, and reports on, such assessment, each as required by Item 1122 of Regulation AB;



(d)        (1) the assessment report and public accounting firm’s attestation report delivered by the Trustee under Section 8.18 (if
required to be delivered by the Trustee under such Section 8.18); and (2) the assessment reports and public accounting firm’s attestation reports delivered by GreenPoint under Section 8.6 of the GreenPoint Regulation AB Addendum;



(e)        a statement of compliance from the Servicer, and a similar statement from each subservicer or other agent or independent contractor
through which the Servicer performs any of its servicing responsibilities hereunder and from each Custodian, in each case, if determined by the Servicer to meet the criteria in Item 1108(a)(2)(i) through (iii) of Regulation AB, as required by Item 1123 of Regulation
AB, signed by an authorized officer, to the effect that:



(i)         a review of the Servicer’s (or, in the case of a statement from any such other party, such other
party’s) activities during the preceding calendar year (or the applicable portion thereof in the case of the initial statement) and of its performance under this Agreement (or the servicing agreement applicable to such other party) has been made under such
officer’s supervision; and



(ii)        to the best of such officer’s knowledge, based on such review, the Servicer (or such other party) has
fulfilled all of its obligations under this Agreement (or the servicing agreement applicable to such other party) in all material respects throughout the preceding calendar 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;



provided, however, that the Servicer shall not be required to deliver the documents described in clauses (c) and (d), and in clause (e) with respect
to any subservicer or other agent or independent contractor, or any Custodian, if such reports are not required to be filed with the Commission as an exhibit to a Report on Form 10-K.



Copies of such reports and statements 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 or GreenPoint, as applicable, 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 Serviced 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 Serviced 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 or GreenPoint, as applicable, designated by it.



Section 3.15.        GreenPoint
Remittance Reports. No later than the fifth (5th) Business Day of each calendar month, GreenPoint shall deliver to the Servicer (or to its designee) an electronic file containing (and, if requested by the Servicer, a hard copy of) a monthly remittance
report with respect to the GreenPoint Loans and relating to the remittance required to be made by GreenPoint in such calendar month under Section 3.03(c), containing such information and in such form as the Servicer may reasonably require in order to allocate
distributions to Certificateholders, prepare monthly distribution reports and perform its other obligations under this Agreement.



Section 3.16.        [Reserved.] 



Section 3.17.        Maintenance of the Class C-PPP Reserve Fund.  
On or prior to the Closing Date, the Trustee shall cause to be established and maintained the Class C-PPP Reserve Fund, into which an amount
equal to $100 shall be contributed by WaMu Capital Corp. On the Distribution Date in March 2011 (or, if the Servicer exercises its purchase option set forth in the first paragraph of Section 9.01(a), or if all the Mortgage Loans are paid in full or liquidated, in
each case before the Distribution Date in March 2011, then on the date of such purchase or payment in full or liquidation), the Trustee shall withdraw from the Class C-PPP Reserve Fund the amount on deposit therein and deposit such amount in the Certificate Account
for payment to the Class C-PPP Certificateholders pursuant to Section 4.05(a).



Amounts on deposit in the Class C-PPP Reserve Fund shall not be invested and shall not be held in an interest-bearing account.



To the extent that it constitutes a “reserve fund” for purposes of the REMIC Provisions, the Class C-PPP Reserve Fund 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 Underwriter, and the
Underwriter 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 Underwriter.



Section 3.18.        [Reserved.] 



Section 3.19.        Determination of LIBOR by
Servicer.  


(a)        With respect to the first Distribution Date, LIBOR shall be the Initial LIBOR Rate. 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 Jones 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 Initial LIBOR Rate) 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 Initial LIBOR Rate).



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.        Prepayment
Penalties on WMB Loans. 



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



(1)        unless the WMB Loan is in default or default is foreseeable and such waiver (i) is standard and customary in
servicing mortgage loans similar to the WMB 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 WMB Loan,



(2)        unless (i) the enforceability thereof is limited 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 (i) the WMB Loan was originated by the Servicer or an
affiliate thereof and (ii) the Mortgagor sells the Mortgaged Property and obtains a new mortgage loan originated and serviced by the Servicer to purchase another property, provided that the prepayment is made no earlier than one year after
origination,



(6)        unless (i) the WMB Loan was originated by the Servicer or an
affiliate thereof and (ii) the Payoff is made on a WMB Loan with a prepayment penalty term greater than twelve months and is made using the proceeds of another mortgage loan originated by the Servicer within 90 days of the end of the
prepayment penalty term, 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 WMB Loan that the Servicer administers for its own account,
or



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



            (b)        If the Servicer has waived all or a portion of a
Prepayment Premium relating to a voluntary Payoff on a WMB Loan in compliance with Section 3.20(a), then the Class C-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 any provision of Section 3.20(a), which materially and adversely affects the Holders of the Class C-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 WMB Custodial Account for P&I 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.



(d)        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 C-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 WMB Custodial Account for P&I within 48 hours or receipt the amounts so received from the Seller.



Section 3.21.        Prepayment
Penalties on GreenPoint Loans. 



(a)        Notwithstanding anything in this Agreement to the contrary, in the event of a Curtailment or Payoff on a GreenPoint Loan, GreenPoint may
not waive any prepayment premium or charge required to be paid under the terms of the related Mortgage Note (a “Prepayment Charge”) or portion thereof:



(1)        unless the GreenPoint Loan is in default (defined as 61 days or more delinquent) and such waiver (i) is standard and
customary in servicing mortgage loans similar to the GreenPoint Loans and (ii) would maximize recovery of total proceeds taking into account the value of such Prepayment Charge and the GreenPoint Loan,



(2)        unless the prepayment is not a result of a refinancing by GreenPoint or any of its affiliates and the GreenPoint Loan is
foreseen to be in default and such waiver (i) is standard and customary in servicing mortgage loans similar to the GreenPoint Loans and (ii) would maximize recovery of total proceeds taking into account the value of such Prepayment Charge and the GreenPoint
Loan,



(3)        unless the collection of the Prepayment Charge would be in violation of applicable laws,



(4)        unless the collection of such Prepayment Charge would be considered “predatory” pursuant to written guidance
published or issued by any applicable federal, state or local regulatory authority acting in its official capacity and having jurisdiction over such matters, or



(5)        unless, notwithstanding any state or federal law to the contrary, the GreenPoint Loan is in foreclosure.



GreenPoint hereby acknowledges that for the purposes of the preceding sentence, state laws prohibiting or limiting prepayment penalties or charges are preempted
and thereby inapplicable if the related originator of the mortgage loans is a federal association or federal bank or an operating subsidiary of such institution.  In the event GreenPoint determines that (i) the foregoing acknowledgement is no longer accurate and
(ii) applicable state law would prevent it from fully enforcing prepayment penalties or charges, GreenPoint shall (i) provide prompt notice to such effect to the Servicer and (ii) provide a written opinion of counsel from a nationally recognized law firm experienced
in regulatory matters concluding that fully enforcing prepayment penalties or charges would violate applicable law.



            (b)        If GreenPoint has waived all or a portion of a
Prepayment Premium relating to a voluntary Payoff on a GreenPoint Loan in compliance with Section 3.21(a), then the Class C-PPP Certificateholders shall not be entitled to the amounts waived.



(c)        Upon discovery by GreenPoint, the Servicer, the Company or the Trustee (in the case of the Trustee, having actual knowledge thereof)
of a breach of any provision of Section 3.21(a), which materially and adversely affects (x) the Holders of the Class C-PPP Certificates or (y) the Servicer (in respect of the Servicer’s right to receive as servicing compensation any Prepayment Charges on
GreenPoint Loans that are not Prepayment Premiums), the party discovering such breach shall give prompt written notice to the other parties.  Within 60 days of the earlier of discovery by GreenPoint, the Servicer, the Company or the Trustee, as applicable, of
such breach, GreenPoint shall cure such breach in all material respects or, if the breach cannot be cured, shall deposit, or cause to be deposited, to the GreenPoint Custodial Account the amount of each impermissibly waived Prepayment Charge (less any amount
collected from the Mortgagor in respect to such Prepayment Charge).



ARTICLE IV



Payments to Certificateholders; Payment of Expenses



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.  Amounts distributed pursuant to clause (ii) above shall be distributed by wire transfer in immediately available funds for the account of each Class R Certificateholder, or by
any other means of payment acceptable to each Class R 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.  Notwithstanding any other provision of this Agreement, no actual distributions pursuant to clause (i) of this Section 4.01 shall be made on account of the deemed distributions described in this paragraph except
in the event of a liquidation of REMIC III and REMIC II and not REMIC I.



Section 4.02.        WMB Monthly P&I
Advances; Distribution Reports to the Trustee.


(a)        To the extent described below, the Servicer is obligated to advance its own funds to the WMB Custodial Account for P&I, or apply funds held in the WMB
Custodial Account for P&I for future distribution, to cover any shortfall between (i) Monthly Payments scheduled to be received in respect of the WMB Loans and (ii) the amounts actually received; provided, however, that with respect to any WMB Loan that is
a Balloon Loan that is delinquent on its maturity date, the Servicer will not be required to advance the related balloon payment but will be required to continue to make advances in accordance with this Section 4.02 with respect to such Balloon Loan in an amount
equal to one month’s interest on the unpaid principal balance at the applicable Pass-Through Rate for each Distribution Date to the extent the Servicer deems such amount to be recoverable.  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 WMB Loans or recoverable as late Monthly Payments with respect to the related WMB 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 WMB 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 WMB Loans, stated separately.


In the event that the Servicer shall be required to make a WMB Monthly P&I Advance, it shall, not later than the Business Day prior to the related Distribution Date either (i) deposit in the WMB
Custodial Account for P&I an amount equal to such WMB Monthly P&I Advance, (ii) make an appropriate entry in the records of the WMB 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 WMB Monthly P&I Advance or (iii) make advances in the form of any combination of (i) and (ii) aggregating the amount of such WMB Monthly P&I Advance.  Any funds being held for future
distribution and so used shall be replaced by the Servicer by deposit in the WMB 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 WMB 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:



(A)       the following information with respect to the Certificates: 



(1) the total amount of (i) interest, (ii) scheduled principal, (iii) Principal Prepayments, (iv) Liquidation Proceeds and Insurance Proceeds, (v) Subsequent Recoveries, (vi)
Repurchase Proceeds and (vii) Yield Maintenance Payment Amounts to be distributed to the Certificates on such Distribution Date;



(2) the amount, as applicable, of (i) interest, (ii) principal, (iii) Excess Liquidation Proceeds and (iv) the Residual Distribution Amount to be distributed to each Class of
Certificates on such Distribution Date;



(3) the amount of (i) Realized Losses (after giving effect to any reduction thereof by application of any Cumulative Carry-Forward Subsequent Recoveries Amount) and (ii)
Uncompensated Interest Shortfall to be allocated to each Class of Certificates on such Distribution Date; 



(4) the applicable Class Principal Balance before and after giving effect to such distributions and allocations;

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, REMIC II and REMIC III to cease to qualify as a REMIC and will not create a risk that (1) REMIC I, REMIC II and REMIC III 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, REMIC II and REMIC III, 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)        (1)        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.



(2)        In the case of any Junior Subordinate 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 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 (B) only if such officer’s certificate indicates that a Benefit Plan Opinion is delivered in connection therewith, a Benefit Plan Opinion.



(3)        Notwithstanding the foregoing, a certification (and, if applicable, a Benefit Plan Opinion) as described in Section 5.01(d)(2) above
will not be required with respect to the transfer of any Junior Subordinate Certificate to a Clearing Agency, or for any subsequent transfer of any interest in a Junior Subordinate Certificate for so long as such Certificate is a Book-Entry Certificate (each such
Junior Subordinate Certificate, a “Book-Entry Junior Subordinate Certificate”).  Any transferee of a Book-Entry Junior Subordinate 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 a Plan Investor or (ii) such transferee is a Complying Insurance Company.



(4)        If any Book-Entry Junior Subordinate Certificate (or any interest therein) is acquired or held in violation of the provisions of
Section 5.01(g)(3) above, then the last preceding transferee that either (i) is not a Plan Investor or (ii) is a Complying Insurance Company 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.



(5)        Any purported Beneficial Holder whose acquisition or holding of any Book-Entry Junior Subordinate Certificate (or interest therein) was
effected in violation of the restrictions in this Section 5.01(d) 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.


(e)        [Reserved.]


(f)         (1)        No transfer, sale, pledge or other disposition of a Junior Subordinate Certificate shall be made unless such
transfer, sale, pledge or other disposition is made in accordance with this Section 5.01(f).  Each Person who, at any time, acquires any ownership interest in any Junior Subordinate 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(f). To effectuate a transfer of a Junior Subordinate Certificate in accordance with this Section 5.01(f), either such transfer shall be made pursuant to an effective registration
statement under the Securities Act or the proposed transferee of such Certificate shall 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 a Junior Subordinate 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.

will be deemed to have represented, by virtue of its acquisition or holding of such Certificate (or interest therein), that such transferee meets the requirements set forth in Exhibit L attached hereto.



(3)        If any Book-Entry Junior Subordinate Certificate (or any interest therein) is acquired or held in violation of the provisions 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 Junior Subordinate Certificate (or interest therein) was
effected in violation of the restrictions in this Section 5.01(f) 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

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

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.

incurred by such parties as a result of such acquisition or holding.


(h)        (1)        In the case of any Class C-PPP 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 P 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(h)(1) above
will not be required with respect to the transfer of any Class C-PPP Certificate to a Clearing Agency, or for any subsequent transfer of any interest in a Class C-PPP Certificate for so long as such Certificate is a Book-Entry Certificate (each such Class C-PPP

transferee is not a Plan Investor.



(3)        If any Book-Entry Class C-PPP Certificate (or any interest therein) is acquired or held in violation of the provisions of Section
5.01(h)(2) above, then the last preceding transferee that is not a Plan Investor 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 Class C-PPP Certificate (or interest therein) was
effected in violation of the restrictions in this Section 5.01(h) 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 Holder’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, Section 4.04 and Section 4.05 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.

accordance with Section 5.06(a), such beneficial owner must notify the Trustee no later than three Business Days before the proposed exchange date.  Notice to the Trustee may be provided by email to team3.abs@abnamro.com and robert.waddell@abnamro.com or by
telecopy at (312) 904-1368. The exchange date will be subject to the Trustee’s approval but may generally be any Business Day other than the first or last Business Day of each calendar month; provided, however, that any exchange shall initially be
reflected in the distributions made on the Distribution Date in the calendar month immediately following the calendar month of the exchange. The notice must (i) be on the beneficial owner’s letterhead, (ii) carry a medallion stamp guarantee or be signed by an
authorized signatory and be presented with an incumbency certificate and (iii) set forth the following information: the CUSIP number of both the Certificates to be exchanged and the Certificates to be received, the outstanding Certificate Principal Balance or
Notional Amount and the initial Certificate Principal Balance or Notional Amount of the Certificates to be exchanged, the beneficial owner’s DTC participant number and the proposed exchange date. After receiving the notice, the Trustee shall e-mail the
beneficial owner with wire payment instructions relating to the exchange fee and, assuming the exchange is a permitted exchange as provided in Section 5.06(a), the beneficial owner shall use the Deposit and Withdrawal System at DTC to exchange the Certificates. A
notice becomes irrevocable on the second Business Day before the proposed exchange date.



In connection with each exchange, the beneficial owner shall pay the Trustee a fee in the amount of $5,000. The exchange shall be completed upon the receipt by the Trustee of the
exchange fee and notice via the Deposit and Withdrawal System at DTC of the delivery of the Certificates to be exchanged.



In the event that the book-entry system with respect to the Book-Entry Certificates shall have been terminated and the Exchangeable Certificates shall have been issued as
Definitive Certificates pursuant to Section 5.09, a Certificateholder who wishes to exchange Exchangeable Certificates shall be required to surrender those Certificates to the Trustee no later than three Business Days before the proposed exchange date.



(c)        Not later than the fifth Business Day of each calendar month, the Trustee shall deliver to the Servicer a report stating either (x)
with respect to each exchange of Exchangeable Certificates that occurred in the prior calendar month, the Class Principal Balance or Class Notional Amount, as applicable, of the Exchangeable Certificates that were exchanged or (y) that no Exchangeable Certificates

On the last day of each calendar month, the Class Principal Balances of the Exchangeable Certificates (other than the Class 1-A-10, Class 1-A-15 and Class 3-A-5 Certificates)
shall be increased (in the case of Exchangeable Certificates received in an exchange) or decreased (in the case of Exchangeable Certificates that were exchanged), as applicable, to reflect all exchanges that have been made pursuant to Section 5.06(a) during such
calendar month..



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 (or its custodian), 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 662⁄3% 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.

most recent financial statements (or, in the case of the Servicer, 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%; 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 (including, without limitation, its covenants and agreements as
successor to GreenPoint, if it has been so appointed under Section 7.02(c) or (d)) 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%; 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 WMB Monthly P&I Advance (other than a WMB Nonrecoverable Advance) which continues unremedied at the opening of business on the Distribution Date in respect of which such WMB 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%, 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 WMB Servicing Fee (and, if acting as successor to GreenPoint under Section 7.02(c) or (d), its right
to the GreenPoint Servicing Fee), under this Agreement. Such termination 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 applicable 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 collections on the Mortgage Loans that shall at the time be held by the Servicer or thereafter be received by the Servicer 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 in any capacity other than Servicer, 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 WMB 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 WMB 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 GreenPoint shall occur and be continuing, that is to say:



(i)                  Any failure by GreenPoint to deposit into the Investment Account any payment required to be deposited therein by GreenPoint under the terms of
this Agreement which continues unremedied for a period of one Business Day after the date upon which written notice of such failure, requiring the same to be remedied, shall have been given to GreenPoint by the Trustee or the Servicer or to GreenPoint and the Trustee
by the Holders of Certificates evidencing Percentage Interests aggregating not less than 25%; or



(ii)                Any
failure by GreenPoint to duly observe or perform in any material respect any other of the covenants or agreements on the part of GreenPoint contained in this Agreement which continues unremedied for a period of 30 days (or, in the case of any failure to pay the
premium for any insurance policy that is required to be maintained hereunder, 15 days) after the date on which written notice of such failure, requiring the same to be remedied, shall have been given to GreenPoint by the Trustee or the Servicer, or to GreenPoint and
the Trustee by the Holders of Certificates evidencing Percentage Interests aggregating not less than 25%; 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 GreenPoint and such decree or order shall have remained in force undischarged or unstayed for a period of 60 days; or



(iv)              GreenPoint 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 GreenPoint or of or relating to all or substantially all
of its property; or



(v)                GreenPoint
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)              GreenPoint shall fail
to be an approved servicer of mortgage loans for Fannie Mae in good standing; or



(vii)             GreenPoint shall attempt
to assign this Agreement or the servicing responsibilities hereunder in contravention of this Agreement; or



(viii)           GreenPoint shall fail to be in
compliance with the “doing business” or licensing laws of any jurisdiction where a Mortgaged Property related to a GreenPoint Loan is located; or



(ix)              GreenPoint ceases to
meet the qualifications of either Fannie Mae or Freddie Mac seller/servicer, GreenPoint is not eligible to act as servicer or master servicer for mortgage loans subject to residential mortgage backed securities transactions rated by any nationally recognized rating
agency or is eligible to act as such only with enhanced credit support, or GreenPoint’s credit rating is reduced by a nationally recognized rating agency below its rating on the Closing Date; or



(x)                GreenPoint
fails to duly perform, within the required time period its obligations under Sections 8.5 and 8.6 of the GreenPoint Regulation AB Addendum, which failure continues unremedied for a period of 3 days after the date on which written notice of such failure, requiring the
same to be remedied, shall have been given to GreenPoint by the Servicer or the Company;


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%, by notice in writing to the Company, the Servicer and GreenPoint (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 GreenPoint, including its right to the GreenPoint Servicing Fee, under this Agreement. Such termination shall be final and
binding. On or after the receipt by GreenPoint of such written notice, all authority and power of GreenPoint under this Agreement, whether with respect to the GreenPoint Loans or otherwise, shall pass to and be vested in the Servicer pursuant to and under this
Section 7.01 and Section 7.02(c); and, without limitation, the Servicer is hereby authorized and empowered to execute and deliver, on behalf of GreenPoint, 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 GreenPoint Loans and related documents, or otherwise. GreenPoint agrees to
cooperate with the Servicer and the Trustee in effecting the termination of GreenPoint's responsibilities and rights hereunder, including, without limitation, the transfer to the Servicer for administration by it of all collections on the GreenPoint Loans that shall
at the time be held by GreenPoint or thereafter be received by GreenPoint with respect to the GreenPoint Loans. GreenPoint agrees that it will reimburse the Trustee and the Servicer for actual, necessary and reasonable costs incurred by the Trustee or the Servicer
because of such Event of Default.


(c)        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%; 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%, 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.


(d)        In any circumstances in which this Agreement states that Certificateholders owning Certificates evidencing a certain Percentage Interest 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 and shall have all the rights and powers and be subject to all the responsibilities, duties and liabilities relating thereto (including, without limitation, the Servicer’s
responsibilities, duties and liabilities as successor to GreenPoint, if it has been so appointed under Section 7.02(c) or (d)) 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 WMB Monthly P&I Advance or GreenPoint 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
WMB Loans (and on the GreenPoint Loans, if the Servicer was acting as successor to GreenPoint under Section 7.02(c) or (d)) 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 or GreenPoint hereunder, in the event that any of the applicable 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).


(c)        On and after the date on which GreenPoint receives a notice of termination pursuant to Section 7.01 or GreenPoint resigns pursuant to Section 6.04, the Servicer
shall be the successor in all respects to GreenPoint under this Agreement 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 GreenPoint by the terms and provisions hereof and thereof, and shall have the same limitations on liability herein granted to GreenPoint; provided, that Servicer shall not under any circumstances be responsible for any representations and warranties or any
repurchase obligation of GreenPoint or any liability incurred by GreenPoint prior to such date of termination or resignation; provided, further, that if the Trustee is acting as successor Servicer under Section 7.02(a), the Trustee shall not be obligated to
make a GreenPoint Monthly P&I Advance if it is prohibited by law from so doing.  As compensation therefor, the Servicer shall be entitled to all compensation to which GreenPoint would have been entitled if GreenPoint had continued to act
hereunder.


(d)        Notwithstanding Section 7.02(c), if the Trustee is acting as successor Servicer under Section 7.02(a), the Trustee may, if it shall be unwilling to act as
successor to GreenPoint, 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 GreenPoint
hereunder in the assumption of all or any part of the responsibilities, duties or liabilities of GreenPoint hereunder. Pending any such appointment, the Trustee (if acting as successor Servicer under Section 7.02(a)) is obligated to act as successor to GreenPoint. In
connection with such appointment and assumption, the Trustee may make such arrangements for the compensation of such successor out of payments on GreenPoint Loans as it and such successor shall agree; provided, however, that no such compensation shall be in
excess of that permitted GreenPoint hereunder. The Trustee and such successor shall take such actions, consistent with this Agreement, as shall be necessary to effectuate any such succession.



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



ARTICLE VIII



Concerning the Trustees



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% 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(a)(i), 7.01(a)(ii), 7.01(b)(i) or Section 7.01(b)(ii), no such notice to Certificateholders or to the Rating Agencies shall be given until
at least 30 days after the occurrence thereof.



Section 8.02.        Certain
Matters Affecting the Trustees. Except as otherwise provided in Section 8.01:



(i)                  Each of the Trustee and the Delaware Trustee may request and rely upon and shall be protected in acting or refraining from acting upon any
resolution, Officer’s Certificate, certificate of auditors or any other certificate, statement, instrument, opinion, report, notice, request, consent, order, approval, bond or other paper or document believed by it to be genuine and to have been signed or
presented by the proper party or parties;



(ii)                Each of
the Trustee and the Delaware Trustee may consult with counsel and any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken or suffered or omitted by it hereunder in good faith and in accordance with such Opinion of
Counsel;



(iii)               Neither the
Trustee nor the Delaware Trustee shall be personally liable for any action taken or omitted by it in good faith and reasonably believed by it to be authorized or within the discretion or rights or powers conferred upon it by this Agreement;



(iv)              Prior to the
occurrence of an Event of Default hereunder and after the curing of all Events of Default which may have occurred, neither the Trustee nor the Delaware Trustee shall be bound to make any investigation into the facts or matters stated in any resolution, certificate,
statement, instrument, opinion, report, notice, request, consent, order, approval, bond or other paper or document, unless requested in writing to do so by the Holders of Certificates evidencing Percentage Interests aggregating not less than 25%; provided,
however, that if the payment within a reasonable time to the Trustee or the Delaware Trustee of the costs, expenses or liabilities likely to be incurred by it in the making of such investigation is, in the opinion of such trustee, not reasonably assured to such
trustee by the security, if any, afforded to it by the terms of this Agreement, such trustee may require reasonable indemnity against such expense or liability as a condition to proceeding;



(v)                Each of
the Trustee and the Delaware Trustee may execute the trust or any of the powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys selected by it with reasonable care or (as in the case of the Initial Custodian) designated
by the Servicer;



(vi)              Neither the Trustee
nor the Delaware Trustee shall be deemed to have knowledge or notice of any matter, including without limitation an Event of Default, unless actually known by a Responsible Officer, or unless written notice thereof referencing this Agreement or the Certificates is
received at the Notice Address of such trustee;



(vii)             In no event shall the
Trustee or the Delaware Trustee be held liable for acts or omissions of the Servicer or the other trustee (excepting the Trustee’s own actions as Servicer).  No provision of this Agreement shall require the Trustee or the Delaware Trustee to expend or risk
its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder (except for the giving of required notices), or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing the repayment
of such funds or adequate indemnity against such risk or liability is not reasonably assured to it;



(viii)           When the Trustee is acting as
Servicer, and to the extent permitted under applicable law, the Trustee is hereby authorized, in making or disposing of any investment permitted hereunder, to deal with itself (in its individual capacity) or with any one or more of its affiliates, whether it or its
affiliate is acting as an agent of the Trustee or of any third person or dealing as principal for its own account;



(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; and



(x)                Except as
provided in this Agreement, 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 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 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. Neither the Trustee nor the Delaware Trustee shall be accountable for the use or application by
the Company, the Servicer or the Trust, as applicable, of any of the Certificates or of the proceeds of such Certificates, or for the use or application of any funds paid to the Servicer or the Company in respect of the Mortgage Loans or deposited into the WMB
Custodial Accounts for P&I, any Buydown Fund Account, the Investment Account or the Certificate Account by the Servicer or the Company.



Section 8.04.        Trustees
May Own Certificates. The Trustee, the Delaware Trustee or any agent or affiliate of such trustee, in its individual or any other capacity, may become the owner or pledgee of Certificates with the same rights it would have if it were not trustee.



Section 8.05.        The
Servicer to Pay Trustees’ Fees and Expenses. 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 of the WMB Loans hereunder or (to the extent such payment or reimbursement is not made by GreenPoint) in connection with a transfer of servicing of the GreenPoint Loans
hereunder, and shall indemnify the institution acting as such trustee, both in its individual capacity and as 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, REMIC II or REMIC III 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.



Section 8.06.        Eligibility Requirements for Trustees. The Trustee hereunder shall at all times be (i) an institution insured by the FDIC, (ii) a Corporation organized and doing business under the laws of the United States of America or of any state, authorized
under such laws to exercise corporate trust powers, having a combined capital and surplus of not less than $50,000,000 and subject to supervision or examination by federal or state authority and (iii) acceptable to the Rating Agencies. If such Corporation publishes
reports of condition at least annually, pursuant to law or to the requirements of any aforementioned supervising or examining authority, then for the purposes of this Section 8.06, the combined capital and surplus of such Corporation shall be deemed to be its
combined capital and surplus as set forth in its most recent report of condition so published.  The Delaware Trustee hereunder shall at all times have its principal place of business in the State of Delaware and shall satisfy the applicable requirements under
the laws of the State of Delaware authorizing it to act as the Delaware trustee of the Trust.  In case at any time the Trustee or the Delaware Trustee shall cease to be eligible in accordance with the provisions of this Section 8.06, such trustee shall resign
immediately in the manner and with the effect specified in Section 8.07.



Section 8.07.        Resignation and Removal of Trustees. Each of the Trustee and the Delaware Trustee may at any time resign and be discharged from the trust hereby created by giving written notice thereof to the Servicer. Upon receiving such notice of resignation,
the Servicer shall promptly appoint a successor trustee by written instrument, in duplicate, one copy of which instrument shall be delivered to the resigning trustee and one copy to the successor trustee. 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.


The Holders of Certificates evidencing Percentage Interests aggregating more than 50% may at any time remove the Trustee or the Delaware Trustee and appoint a successor trustee by written instrument or
instruments, in triplicate, signed by such Holders or their attorneys in-fact duly authorized, one complete set of which instruments shall be delivered to the Servicer, one complete set to the trustee so removed and one complete set to the successor so
appointed.


Any resignation or removal of the Trustee or the Delaware Trustee and appointment of a successor trustee pursuant to any of the provisions of this Section 8.07 shall become effective upon acceptance of
appointment by the successor trustee as provided in Section 8.08. 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.


No successor trustee shall accept appointment as provided in this Section 8.08 unless at the time of such appointment such successor trustee shall be eligible under the provisions of Section
8.06.


Upon acceptance of appointment by a successor trustee as provided in this Section 8.08, the Servicer shall mail notice of the succession of such trustee hereunder to (i) all Certificateholders at their
addresses as shown in the Certificate Register and (ii) the Rating Agencies. If the Servicer fails to mail such notice within ten days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be mailed.



Section 8.09.        Merger or
Consolidation of Trustee. Any Corporation into which the Trustee or the Delaware Trustee may be merged or converted or with which it may be consolidated, or any Corporation resulting from any merger, conversion or consolidation to which the Trustee or
the Delaware Trustee shall be a party, or any Corporation succeeding to the corporate trust business of such trustee, shall be the successor of such trustee hereunder, provided such resulting or successor Corporation shall be eligible under the provisions of Section
8.06, 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 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. Wherever reference is made in this Agreement to the authentication of
Certificates by the Trustee or the Trustee’s certificate of authentication, such reference shall be deemed to include authentication on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an
Authenticating Agent. Each Authenticating Agent must be acceptable to the Servicer and must be a corporation, trust company or banking association organized and doing business under the laws of the United States of America or of any state, having an office and place
of business in New York, New York, having a combined capital and surplus of at least $15,000,000, authorized under such laws to do a trust business and subject to supervision or examination by federal or state authorities.


Any corporation into which any Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which any
Authenticating Agent shall be a party, or any corporation succeeding to the corporate agency business of any Authenticating Agent, shall continue to be the Authenticating Agent so long as it shall be eligible in accordance with the provisions of the first paragraph
of this Section 8.11 without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent.


Any Authenticating Agent may at any time resign by giving written notice of resignation to the Trustee and the Servicer. The Trustee may, upon prior written approval of the Servicer, at any time terminate
the agency of any Authenticating Agent by giving written notice of termination to such Authenticating Agent and to the Servicer. Upon receiving a notice of resignation or upon such a termination, or in case at any time any Authenticating Agent shall cease to be
eligible in accordance with the provisions of the first paragraph of this Section 8.11, the Trustee may appoint, upon prior written approval of the Servicer, a successor Authenticating Agent, shall give written notice of such appointment to the Servicer and shall
mail notice of such appointment to all Certificateholders. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers, duties and responsibilities of its predecessor hereunder, with like effect as
if originally named as Authenticating Agent. Any reasonable compensation paid to an Authenticating Agent shall be a reimbursable expense pursuant to Section 8.05 if paid by the Trustee.



Section 8.12.        Paying
Agents. The Trustee may appoint one or more Paying Agents which shall be authorized to act on behalf of the Trustee in making withdrawals from the Certificate Account, and distributions to Certificateholders as provided in Section 4.01, Section 4.04,
Section 4.05(a) and Section 9.01(b) to the extent directed to do so by the Servicer. Wherever reference is made in this Agreement to the withdrawal from the Certificate Account by the Trustee, such reference shall be deemed to include such a withdrawal on behalf of
the Trustee by a Paying Agent. Whenever reference is made in this Agreement to a distribution by the Trustee or the furnishing of a statement to Certificateholders by the Trustee, such reference shall be deemed to include such a distribution or furnishing on behalf
of the Trustee by a Paying Agent. Each Paying Agent shall provide to the Trustee such information concerning the Certificate Account as the Trustee shall request from time to time. Each Paying Agent must be reasonably acceptable to the Servicer and must be a
corporation, trust company or banking association organized and doing business under the laws of the United States of America or of any state, having an office and place of business in New York, New York, having a combined capital and surplus of at least $15,000,000,
authorized under such laws to do a trust business and subject to supervision or examination by federal or state authorities.


Any corporation into which any Paying Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which any Paying
Agent shall be a party, or any corporation succeeding to the corporate agency business of any Paying Agent, shall continue to be the Paying Agent provided that such corporation after the consummation of such merger, conversion, consolidation or succession meets the
eligibility requirements of this Section 8.12.


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. Upon receiving a notice of resignation or upon such a termination, or in case at any time any Paying Agent shall cease to be eligible in accordance with the provisions of the first paragraph of this Section 8.12,
the Trustee may appoint, upon prior written approval of the Servicer, a successor Paying Agent, shall give written notice of such appointment to the Servicer and shall mail notice of such appointment to all Certificateholders. Any successor Paying Agent upon
acceptance of its appointment hereunder shall become vested with all the rights, powers, duties and responsibilities of its predecessor hereunder, with like effect as if originally named as Paying Agent. Any reasonable compensation paid to any Paying Agent shall be a
reimbursable expense pursuant to Section 8.05 if paid by the Trustee.

Section 9.01.        Termination Upon Purchase by
the Servicer or Liquidation of All Mortgage Loans.


(a)        The Servicer may purchase the outstanding Mortgage Loans, all property acquired by the Trust in respect of any Mortgage Loan and all other property included in
any REMIC formed under this Agreement at the price stated in clause (i) of the second paragraph of this Section 9.01(a) on or after the first date on which the aggregate Principal Balance of the Mortgage Loans is less than the Clean-Up Call Percentage of the
aggregate Principal Balance of the Mortgage Loans as of the Cut-Off Date; provided, however, that the Servicer may not so purchase such outstanding Mortgage Loans and property if the price stated in such clause (i) exceeds the fair market value, determined by
the Servicer in accordance with prudent industry practices, of such outstanding Mortgage Loans and property. If such right is exercised, the Servicer shall provide to the Trustee, the Delaware Trustee and the Company the written certification of an officer of the
Servicer (which certification shall include a statement to the effect that all amounts required to be paid in order to exercise such right have been deposited in the Certificate Account) and the Trustee on behalf of the Trust shall promptly execute all instruments as
may be necessary to release and assign to the Servicer the Mortgage Loans, all property acquired by the Trust in respect of any Mortgage Loan and all other property included in any REMIC formed under this
Agreement.


Except as otherwise set forth in this Article IX, including, without limitation, the obligation of the Servicer to make payments to Certificateholders as hereafter set forth, the Trust and the respective
obligations and responsibilities of the Company, the Servicer, GreenPoint, the Trustee and the Delaware Trustee created hereby shall terminate in accordance with Section 3808 of the Statutory Trust Statute upon:



(i)         the Distribution Date immediately following the exercise by the Servicer of its purchase option set forth in the first paragraph
of this Section 9.01(a), of all Mortgage Loans, all property acquired by the Trust in respect of any Mortgage Loan by foreclosure, deed in lieu of foreclosure or otherwise, and all other property included in any REMIC formed under this Agreement, at a price equal to
the sum, reduced by unreimbursed advances (other than advances made with respect to Mortgage Loans as to which the Servicer expects at the time of such purchase, in its sole judgment, that foreclosure is not imminent), of



(x)        the excess of



(A)       100% of the aggregate Principal Balance of the Mortgage Loans (other than Mortgage Loans in respect of which the related Mortgaged Property
has been acquired by the Trust by foreclosure, deed in lieu of foreclosure or otherwise) (after giving effect to the distribution of all other principal and the allocation of Realized Losses to the Certificates on the date of such purchase), plus accrued interest at
the applicable Pass-Through Rates with respect to such Mortgage Loans through the last day of the month of such purchase, over



(B)       the amount of any Bankruptcy Losses incurred with respect to such Mortgage Loans as of the date of such purchase to the extent that the
Principal Balances of such Mortgage Loans have not been previously reduced by such Bankruptcy Losses, and



(y)        without duplication,



(A)       the appraised fair market value as of the date of such purchase of all property owned by the Trust which secured a Mortgage Loan and which
has been acquired by the Trust by foreclosure, deed in lieu of foreclosure or otherwise, including related Insurance Proceeds, and



(B)       the appraised fair market value as of the date of such purchase of all other property included in any REMIC formed under this Agreement, any
such appraisal pursuant to clause (A) or (B) to be conducted by an appraiser mutually agreed upon by the Servicer and the Trustee, or



(ii)        the later of the final payment or other liquidation (or any advance with respect thereto) of the last Mortgage Loan owned by the Trust
or the disposition of all property acquired upon foreclosure in respect of any Mortgage Loan, and the payment to the Certificateholders of all amounts required to be paid to them hereunder.


The Servicer shall not have any further right to reimbursement by the Trust for any advance that is used to reduce the purchase price of the Mortgage Loans pursuant to the immediately preceding
sentence.


In no event shall the Trust continue beyond the expiration of 21 years from the death of the survivor of the issue of Joseph P. Kennedy, the late ambassador of the United States to the Court of St.
James’, living on the date hereof.


In no event shall the Servicer be required to expend any amounts other than those described in the second paragraph of this Section 9.01(a) in order to terminate the Trust or purchase the Mortgage Loans
under this Section 9.01, and in no event shall the Company, the Trustee or the Delaware Trustee be required to expend any amounts in connection with such termination or purchase.


(b)        Notice of such purchase pursuant to Section 9.01(a), 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 the 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. The Servicer shall provide the
Trustee with written notice of its intent to exercise its purchase option pursuant to Section 9.01(a) 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, REMIC II and REMIC III 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, REMIC II and REMIC III 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, REMIC II and REMIC III as described in Section 860F of the Code, or (ii) cause REMIC I, REMIC II or REMIC III 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, REMIC II and REMIC III 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, REMIC II and REMIC III; 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, REMIC II and REMIC III 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.

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.

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

Appendix 1:  Definition of Class C-Y Principal Reduction Amounts



 



 


                For any Distribution Date the amounts by which the Class Principal Balances of the Class C-Y-1, Class C-Y-2 and 
Class C-Y-3 Regular Interests respectively will be reduced on such distribution date by the allocation of Realized Losses and the distribution of principal, determined as follows:


 


                First for each of Subgroup 1-1, Subgroup 1-2 and Groups 2&3 determine the pass-through rate for that Group for
distributions of interest that will be made on the next succeeding Distribution Date (the “Group Interest Rate”).  The Principal Reduction Amount for each of the Class Y Regular Interests will be determined pursuant to the “Generic solution for
the Class Y Principal Reduction Amounts” set forth below (the “Generic Solution”) by making identifications among the actual Groups or Subgroups and their related Class Y and Class Z Regular Interests and pass-through rates and the Groups named in
the Generic Solution and their related Class Y and Class Z Regular Interests as follows:


 



A.  Groups 2&3 have the lowest Group Interest Rate.  Those Groups will be identified with Group AA and the Class Y Regular Interest and Class Z Regular
Interest  related to that Group will be respectively identified with the Class YAA and Class ZAA Regular Interests.  The Group Interest Rate (5.50%) for that Group will be identified with J%. 



 



B.  Subgroup 1-1 has the second lowest Group Interest Rate.  That Subgroup will be identified with Group BB and the Class Y Regular Interest and Class Z Regular
Interest related to that Group will be respectively identified with the Class BB and Class ZBB Regular Interests.  The Group Interest Rate (6.00%) for that Group will be identified with K%. 



 



C.  Subgroup 1-2 has the third lowest Group Interest Rate.  That Subgroup will be identified with Group CC and the Class Y Regular Interest and Class Z Regular
Interest  related to that Group will be respectively identified with the Class YCC and Class ZCC Regular Interests.  The Group Interest Rate (7.00%) for that Group will be identified with L%. 


 


                Generic Solution for Class Y Principal Reduction Amounts:  For any Distribution
Date, the amounts by which the principal balances of the Class YAA, Class YBB and Class YCC Regular Interests respectively will be reduced on such Distribution Date by the allocation of Realized Losses and the distribution of principal, determined as
follows:


 


For purposes of the succeeding formulas the following symbols shall have the meanings set forth below:

                = (J% Yj + K% Yk)/(Yj + Yk)


 


r2 =          the weighted average of the Class YCC and Class YBB Certificate Interest Rates

DZk =      the Class ZBB Principal Reduction Amount.



 



Pj =         the aggregate of the Class YAA and Class ZAA Principal Balances after distributions on the prior
Distribution Date, which is equal to the aggregate principal balance of the Group AA Loans reduced by the Group AA Class P Principal Balance, if any, and the Class R Principal Balance, if applicable.

=              Yk + Zk



 



DPj =       the aggregate principal reduction resulting on such Distribution Date on the Group AA Loans as a
result of principal distributions (exclusive of any distributions made pursuant to clause (d)(i) of the definition of the REMIC I Distribution Amount) to be made and Realized Losses to be allocated on such Distribution Date, reduced by the portion , if any, of such
reduction allocable to the Group AA Class P Regular Interest or the Class R Certificates, if applicable, which is equal to the aggregate of the Class YAA and Class ZAA Principal Reduction Amounts.



=

DPl=        the aggregate principal reduction resulting on such Distribution Date on the Group CC Loans as
a result of principal distributions (exclusive of any distributions made pursuant to clause (d)(i) of the definition of the REMIC I Distribution Amount) to be made and Realized Losses to be allocated on such Distribution Date, reduced by the portion , if any, of such

g1 is a non-negative number unless its denominator is zero, in which event it is undefined.



 



g2 =          (R – J%)/( R2 - R).  If

If

In the remaining situations,

dYk =       ((J% - R1)/(K% - R1))Yj + Yk

P4 =         Pj + Pk.

1.        If Yl -
 a(Pl -

3 0, and
 g1(P4 -

DPl), 
DYl = Yl -  
ag1(P4 -

2.        If Yl ‐

DPl)  3 0, Y4 ‐

DYl = Yl ‐  
a(Pl ‐  
DPl)
and  DY4 = Y4 ‐ (a/g1)(Pl ‐

3.        If Yl ‐

a(P4 ‐   DP4).



4.        If Yl ‐

 dYk)])Y4



 



ΔYk =
 dYk + [(Yk - 
dYk)/(Yj + Yk - 
dYk)])Y4


 


The purpose of the foregoing definitional provisions together with the related provisions allocating Realized Losses and defining the Class Y and Class Z Principal Distribution Amounts is to accomplish the
following goals in the following order of priority:



 



1.        Making the ratio of (Yl -
ΔYl ) to (Y4 - ΔY4 ) equal to
 g1 after taking account of the allocation Realized Losses and the distributions that will be made
through the end of the Distribution Date to which such provisions relate and assuring that the Principal Reduction Amount for each of the Class YAA, Class YCC, Class YBB, Class ZAA Class ZCC and Class ZBB Regular Interests is greater than or equal to zero for such
Distribution Date;



2.        Making the Class YAA Principal Balance less than or
equal to 0.0005 of the sum of the Class YAA and Class ZAA Principal Balances, the Class YCC Principal Balance less than or equal to 0.0005 of the sum of the Class YCC and Class ZCC Principal Balances and the Class YBB Principal Balance less than or equal to 0.0005 of
the sum of the Class YBB and Class ZBB Principal Balances in each case after giving effect to allocations of Realized Losses and distributions to be made through the end of the Distribution Date to which such provisions relate; and



3.        Making the larger of (a) the fraction whose
numerator is (Yl - ΔYl ) and whose denominator is the sum of (Yl - ΔYl) and (Zl - ΔZl) and (b) the fraction whose numerator is (Y4 - ΔY4) and whose
denominator is the sum of (Y4 - ΔY4), (Zj - ΔZj) and (Zk - ΔZk) as large as possible while remaining less than or equal to 0.0005.


 


In the event of a failure of the foregoing portion of the  definition of Class Y Principal Reduction Amounts to accomplish both of goals 1 and 2 above, the amounts thereof should be adjusted so as to
accomplish such goals within the requirement that each Class Y Principal Reduction Amount must be less than or equal to the sum of (a) the principal portion of Realized Losses to be allocated on the related Distribution Date for the related Group remaining after the
allocation of such Realized Losses to the related Class P Certificates, if any, and (b) the remainder of the REMIC I Available Distribution Amount for the related Group after reduction thereof by the distributions to be made on such Distribution Date (i) to the
related Class P Certificates, if any, (ii) to the related Class X Certificates, if any, and (iii) in respect of interest on the related Class Y and Class Z Regular Interests, or, if both of such goals cannot be accomplished within such requirement, such adjustment as
is necessary shall be made to accomplish goal 1 within such requirement.  In the event of any conflict among the provisions of the definition of the Class Y Principal Reduction Amounts, such conflict shall be resolved on the basis of the goals and their
priorities set forth above within the requirement set forth in the preceding sentence.  If the formula allocation of ΔY4 between ΔYj and ΔYk cannot be achieved because either ΔYj as so defined
is greater than ΔPj or ΔYk as so defined is greater than ΔPk, such an allocation shall be made as close as possible to the formula allocation within the requirement that ΔYj < ΔPj
and ΔYk < ΔPk.



 



II.  If R3K% and r1<R1, make the following additional
definitions:



 



dYj =       Yj + ((R1 – K%)/(R1 – J%))Yk



 



dYj is a number between Yj and 0 such that (J%(Yj - 
dYj)  + K%Yk)/(Yj - 
dYj + Yk.) = R1.



 



Y5 =         Yj -
 dYj +
Yk.



 



P5 =         Pj + Pk.



 



ΔY5 =      ΔYj -
 dYj +
ΔYk.

The purpose of the foregoing definitional provisions together with the related provisions allocating Realized Losses and defining the Class Y and Class Z Principal Distribution Amounts is to accomplish the
following goals in the following order of priority:



 


	Making the ratio of (Yl - ΔYl) to (Y5 - ΔY5) equal to
 g1 after taking account of the allocation Realized Losses and the distributions that will be made through end of the Distribution Date to which such provisions relate and assuring that the Principal Reduction Amount for each of the Class YAA, Class YCC, Class YBB,
Class ZAA Class ZCC and Class ZBB Regular Interests is greater than or equal to zero for such Distribution Date;
	Making the Class YAA Principal Balance less than or equal to 0.0005 of the sum of the Class YAA and Class ZAA Principal Balances, the Class YCC Principal Balance less than or equal to 0.0005 of the sum of
the Class YCC and Class ZCC Principal Balances and the Class YBB Principal Balance less than or equal to 0.0005 of the sum of the Class YBB and Class ZBB Principal Balances in each case after giving effect to allocations of Realized Losses and distributions to be
made through the end of the Distribution Date to which such provisions relate; and
	Making the larger of (a) the fraction whose numerator is (Yl - ΔYl) and whose denominator is the sum of (Yl - ΔYl) and (Zl -
ΔZl) and (b) the fraction whose numerator is (Y5 - ΔY5) and whose denominator is the sum of (Y5 - ΔY5), (Zj - ΔZj) and (Zk - ΔZk) as large
as possible while remaining less than or equal to 0.0005.



 


In the event of a failure of the foregoing portion of the  definition of Class Y Principal Reduction Amounts to accomplish both of goals 1 and 2 above, the amounts thereof should be adjusted so as to
accomplish such goals within the requirement that each Class Y Principal Reduction Amount must be less than or equal to the sum of (a) the principal portion of Realized Losses to be allocated on the related Distribution Date for the related Group remaining after the
allocation of such Realized Losses to the related Class P Certificates, if any, and (b) the remainder of the REMIC I Available Distribution Amount for the related Group or after reduction thereof by the distributions to be made on such Distribution Date (i) to the

WASHINGTON MUTUAL MORTGAGE PASS-THROUGH CERTIFICATE


 


 


This Certificate is one of a duly authorized issue of Certificates designated as Washington Mutual Mortgage Pass-Through Certificates of the Series and Class specified hereon (herein called the
“Certificates”) and representing a beneficial interest in the Trust.


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 applicable
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 applicable servicer of advances made, or certain expenses incurred, by it.


The Pooling Agreement permits, with certain exceptions therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Certificateholders under
the Pooling Agreement at any time by the Company, the Servicer, GreenPoint and the Trustee with the consent of the Holders of the Certificates evidencing Percentage Interests aggregating not less than 66%. The Pooling Agreement also permits the amendment thereof, in
certain limited circumstances, without the consent of the Holders of any of the Certificates.


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 Holder'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.

WASHINGTON MUTUAL MORTGAGE PASS-THROUGH CERTIFICATE


 


 


This Certificate is one of a duly authorized issue of Certificates designated as Washington Mutual Mortgage Pass-Through Certificates of the Series and Class specified hereon (herein called the
“Certificates”) and representing a beneficial interest in the Trust.


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 applicable
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 applicable servicer of advances made, or certain expenses incurred, by it.


The Pooling Agreement permits, with certain exceptions therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Certificateholders under
the Pooling Agreement at any time by the Company, the Servicer, GreenPoint and the Trustee with the consent of the Holders of the Certificates evidencing Percentage Interests aggregating not less than 66%. Any such consent by the Holder of this Certificate shall be
conclusive and binding on such Holder and upon all future Holders of this Certificate and of any Certificate issued upon the transfer hereof or in exchange herefor or in lieu hereof whether or not notation of such consent is made upon this Certificate. The Pooling
Agreement also permits the amendment thereof, in certain limited circumstances, without the consent of the Holders of any of the Certificates.


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 Holder'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.


[FOR ONLY THE PRIVATELY OFFERED CERTIFICATES] [No transfer of a Certificate will be made unless such transfer is exempt from or is made in accordance with the registration requirements of the Securities Act
of 1933, as amended (the “Securities Act”) and any applicable state securities laws. In the event that a transfer is to be made without registration or qualification under applicable laws, (i) in the event such transfer is made pursuant to Rule 144A under
the Securities Act, the Company and the Trustee may require the transferee to execute an investment letter in substantially the form attached as Exhibit L to the Pooling Agreement, which investment letter shall not be an expense of the Company, the Servicer,
GreenPoint, the Trust, the Delaware Trustee or the Trustee and (ii) in the event that such a transfer is not made pursuant to Rule 144A under the Securities Act, the Trustee may require an Opinion of Counsel satisfactory to the Trustee that such transfer may be made
without such registration or qualification, which Opinion of Counsel shall not be an expense of the Company, the Servicer, GreenPoint, the Trust, the Trustee or the Delaware Trustee.  Neither the Company nor the Trust will register the Certificate under the
Securities Act, qualify the Certificate under any state securities law or provide registration rights to any purchaser. Any Holder desiring to effect such transfer shall, and does hereby agree to, indemnify the Trust, the Trustee, the Delaware Trustee, the Company,
the Servicer and GreenPoint against any liability that may result if the transfer is not made in accordance with the Pooling Agreement.]


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.


[FOR ONLY THE EXCHANGEABLE CERTIFICATES][This Certificate is an Exchangeable Certificate. As provided in the Pooling Agreement and subject to certain limitations therein set forth, Initial Exchangeable
Certificates may be exchanged for certain combinations of Certificates of one or more Classes of Subsequent Exchangeable Certificates, and, once issued, certain combinations of Subsequent Exchangeable Certificates may be exchanged for Initial Exchangeable
Certificates, in each case, upon giving notice to the Trustee and payment of an exchange fee to the Trustee.]


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.

Re:      WaMu Asset Acceptance Corp. Washington Mutual Mortgage Pass-Through Certificates, WMALT Series 2007-2, Class R


Ladies and Gentlemen:


This letter is delivered to you in connection with the sale from
                                          (the
“Seller”) to           
                                    (the “Purchaser”) of
$____________________ initial Certificate Principal Balance of Washington Mutual Mortgage Pass-Through Certificates, WMALT Series 2007-2, Class R (the “Certificate”), pursuant to Section 5.01 of the Pooling and Servicing Agreement (the “Pooling
Agreement”), dated as of March 1, 2007 among WaMu Asset Acceptance Corp., as depositor (the "Company"), Washington Mutual Bank, as servicer (the “Servicer”), GreenPoint Mortgage Funding, Inc., as servicer, LaSalle Bank National Association, as
trustee (the “Trustee”), and Christiana Bank & Trust Company, as Delaware trustee. All terms used herein and not otherwise defined shall have the meanings set forth in the Pooling Agreement. The Seller hereby certifies, represents and warrants to, and
covenants with, the Company, the Servicer, the Trustee and the Trust that:


1.         No purpose of the Seller relating to the sale of the Certificate by the Seller to the Purchaser is or will be to enable the Seller to impede the assessment
or collection of tax.


2.         The Seller understands that the Purchaser has delivered to the Trustee and the Company a transferee affidavit and agreement in the form attached to the
Pooling Agreement as Exhibit J. The Seller does not know or believe that any representation contained therein is false.


3.         The Seller has no actual knowledge that the proposed Transferee is not a Permitted Transferee.


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.


5.         The Seller has conducted a reasonable investigation of the financial condition of the Purchaser and, as a result of the investigation, found that the
Purchaser has historically paid its debts as they came due, and found no significant evidence to indicate that the Purchaser will not continue to pay its debts as they come due in the future.






6.         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.


	
 

	
Very truly yours,

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, REMIC II and REMIC III (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]:

SUPPLEMENTARY INFORMATION:



 



Paperwork Reduction Act



 


The collection of information in this final rule has been reviewed and, pending receipt and evaluation of public comments, approved by the Office of Management and Budget (OMB) under 44 U.S.C. 3507 and
assigned control number 1545-1675.  The collection of information in this regulation is in Sec. 1.860E-1(c)(5)(ii). This information is required to enable the IRS to verify that a taxpayer is complying with the conditions of this regulation. The collection of
information is mandatory and is required. Otherwise, the taxpayer will not receive the benefit of safe harbor treatment as provided in the regulation. The likely respondents are businesses and other for-profit institutions.


Comments on the collection of information should be sent to the Office of Management and Budget, Attn: Desk Officer for the Department of the Treasury, Office of Information and Regulatory Affairs,
Washington, DC, 20503, with copies to the Internal Revenue Service, Attn: IRS Reports Clearance Officer, W:CAR:MP:FP:S, Washington, DC 20224. Comments on the collection of information should be received by September 17, 2002. Comments are specifically requested
concerning: 


Whether the collection of information is necessary for the proper performance of the functions of the Internal Revenue Service, including whether the information will have practical
utility; 


The accuracy of the estimated burden associated with the collection of information (see below);


How the quality, utility, and clarity of the information to be collected may be enhanced;


How the burden of complying with the collection of information may be minimized, including through the application of automated collection techniques or other forms of information technology;
and


Estimates of capital or start-up costs and costs of operation, maintenance, and purchase of service to provide information.


An agency may not conduct or sponsor, and a person is not required to respond to, a collection of information unless it displays a valid control number assigned by the Office of Management and
Budget.


The estimated total annual reporting burden is 470 hours, based on an estimated number of respondents of 470 and an estimated average annual burden hours per respondent of one hour.


Books or records relating to a collection of information must be retained as long as their contents may become material in the administration of any internal revenue law. Generally, tax returns and tax
return information are confidential, as required by 26 U.S.C. 6103.


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.

Regulation AB Addendum to compliance with Regulation AB include provision of comparable disclosure in private offerings.



None of the Company, the Trust or the Servicer shall exercise its right to request delivery of information or other performance under these provisions other than in good faith, or
for purposes other than compliance with the Securities Act, the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and the rules and regulations of the Commission thereunder (or the provision in a private offering of disclosure
comparable to that required under the Securities Act). GreenPoint acknowledges that interpretations of the requirements of Regulation AB may change over time, whether due to interpretive guidance provided by the Commission or its staff, consensus among participants
in the asset-backed securities markets, advice of counsel, or otherwise, and agrees to comply with requests made by the Company, the Trust or the Servicer in good faith for delivery of information under these provisions on the basis of evolving interpretations of
Regulation AB. GreenPoint shall cooperate fully with the Company, the Trust and the Servicer to deliver to the Company, the Trust and the Servicer (including any of their assignees or designees), any and all statements, reports, certifications, records and any other
information necessary in the good faith determination of the Company, the Trust or the Servicer to permit the Company, the Trust or the Servicer to comply with the provisions of Regulation AB, together with such disclosures relating to GreenPoint, any
“Subservicer” (defined as any person that services GreenPoint Loans on behalf of GreenPoint or any Subservicer and is responsible for the performance (whether directly or through Subservicers or Subcontractors) of a substantial portion of the
material servicing functions required to be performed by GreenPoint under this Agreement that are identified in Item 1122(d) of Regulation AB), any originator of the GreenPoint Loans other than GreenPoint (a “Third-Party Originator”) and the
GreenPoint Loans, or the servicing of thereof, reasonably believed by the Company, the Trust or the Servicer to be necessary in order to effect such compliance.



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

(i)                  On or before March 1 of each calendar year, commencing in 2008, GreenPoint shall:



(1)        deliver to the Company, the Trust and the Servicer a report (in form and substance reasonably satisfactory to the
Company, the Trust and the Servicer) regarding GreenPoint’s assessment of compliance with the “servicing criteria” set forth in Item 1122(d) of Regulation AB, as such may be amended from time to time (the “Servicing Criteria”),

shall not be necessary for GreenPoint to seek the consent of the Company, the Trust or the Servicer to the utilization of any Subservicer. GreenPoint shall cause any Subservicer used by GreenPoint (or by any Subservicer) with respect to the GreenPoint Loans to comply
with the provisions of this Section and with Sections 8.3, 8.4(iii), (v), (vi) and (vii), 8.5, 8.6 and 8.8 to the same extent as if such Subservicer were GreenPoint, and to provide the information required with respect to such Subservicer under Section 8.4(iv).
GreenPoint shall be responsible for obtaining from each Subservicer and delivering to the Company, the Trust and the Servicer any servicer compliance statement required to be delivered by such Subservicer under Section 8.5, any assessment of compliance and
attestation required to be delivered by such Subservicer under Section 8.6 and any certification required to be delivered to the Person that will be responsible for signing the Sarbanes Certification under Section 8.6 as and when required to be delivered.

GreenPoint shall cause any such Subcontractor used by GreenPoint (or by any Subservicer) for the benefit of the Company, the Trust and the Servicer to comply with the provisions of Sections 8.6 and 8.8 to the same extent as if such Subcontractor were GreenPoint.
GreenPoint shall be responsible for obtaining from each Subcontractor and delivering to the Company, the Trust and the Servicer any assessment of compliance and attestation required to be delivered by such Subcontractor under Section 8.6, in each case as and when
required to be delivered.

(a)        GreenPoint shall indemnify the Company,
the Trust and the Servicer, each affiliate thereof and each of the following parties with respect to the Certificates: each sponsor and issuing entity; each Person responsible for the preparation, execution or filing of any report required to be filed with the

expenses that any of them may sustain arising out of or based upon:

Information a material fact required to be stated in the GreenPoint Information or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, by way of clarification, that clause (B) of
this paragraph shall be construed solely by reference to the GreenPoint Information and not to any other information communicated in connection with a sale or purchase of securities, without regard to whether the GreenPoint Information or any portion thereof is
presented together with or separately from such other information;


(ii)                any breach by GreenPoint of its
obligations under this GreenPoint Regulation AB Addendum or any failure by GreenPoint, any Subservicer, any Subcontractor or any Third-Party Originator to deliver any information, report, certification, accountants’ letter or other material when and as required
under this GreenPoint Regulation AB Addendum, including any failure by GreenPoint to identify pursuant to Section 8.7(ii) any Subcontractor “participating in the servicing function” within the meaning of Item 1122 of Regulation AB; or

in a writing furnished pursuant to Section 8.3(ii) to the extent made as of a date subsequent to the Closing Date; or


(iv)              the negligence, bad faith or willful misconduct of
GreenPoint in connection with its performance under this GreenPoint Regulation AB Addendum.


If the indemnification provided for herein is unavailable or insufficient to hold harmless an Indemnified Party, then GreenPoint agrees that it shall contribute to the amount paid or payable by such
Indemnified Party as a result of any claims, losses, damages or liabilities incurred by such Indemnified Party in such proportion as is appropriate to reflect the relative fault of  such Indemnified Party on the one hand and GreenPoint on the
other. 


In the case of any failure of performance described in clause (a)(ii) of this Section, GreenPoint shall promptly reimburse the Company, the Trust, the Servicer, as applicable, and each Person responsible for
the preparation, execution or filing of any report required to be filed with the Commission with respect to the Certificates, or for execution of a certification pursuant to Rule 13a-14(d) or Rule 15d-14(d) under the Exchange Act with respect to the Certificates, for
all costs reasonably incurred by each such party in order to obtain the information, report, certification, accountants’ letter or other material not delivered as required by GreenPoint, any Subservicer, any Subcontractor or any Third-Party
Originator.


This indemnification shall survive the termination of this Agreement or the termination of any party to this Agreement.
