Capitalized terms used in this Agreement and not otherwise defined will have the meanings assigned to them in Article I below.

PRELIMINARY STATEMENT

The Depositor is the owner of the Trust Fund that is hereby conveyed to the Trustee in return for the Certificates. The Trust Fund for federal income tax purposes will consist of four REMICs (“Subsidiary REMIC 1A”, “Subsidiary REMIC 1B,” Subsidiary REMIC 2 and the “Master REMIC”).

Subsidiary REMIC 1A will consist of all of the assets constituting the Trust Fund corresponding to Loan Group I, Loan Group II and Loan Group III and will be evidenced by the following uncertificated 11 interests that shall be designated as REMIC regular interests: the LT1-I Interest, the LT2-I Interest, the LT3-I Interest, the LT1-II Interest, the LT2-II Interest, the LT3-II Interest, the LT1-III Interest, the LT2-III Interest, the LT3-III Interest, the LT-AS-1 Interest, the LT-AS-2 Interest and the LT-AS-3 Interest (the “Subsidiary REMIC 1A Regular Interests”). In addition, Subsidiary REMIC 1A shall issue the R-1a interest and shall designate such interest as its sole class of residual interest.

Subsidiary REMIC 1B shall hold as its assets the uncertificated REMIC regular interests issued by Subsidiary REMIC 1A and shall issue the following uncertificated REMIC regular interests: the LT-I-A-1 Interest, the LT-I-AR Interest, the LT-II-A-1 Interest, the LT-II-A-2 Interest, the LT-III-A-1 Interest, the LT-C-B-1 Interest, the LT-C-B-2 Interest, the LT-C-B-3 Interest, the LT-C-B-4 Interest, the LT-C-B-5 Interest and the LT-C-B-6 Interest (the “Subsidiary REMIC 1B Regular Interests”) which will be uncertificated and will represent the “regular interests” in Subsidiary REMIC 1B and the R-1b Interest as the single “residual interest” in Subsidiary REMIC 1B.

Subsidiary REMIC 2 will consist of the Loan Group IV Mortgage Loans and will be evidenced by the LT-IV-A-1 Interest, LT-IV-M-1 Interest, LT-IV-M-2 Interest and LT–Accrual Interest, (collectively, the LT-IV-A Interest, LT-IV-M-1 Interest and LT-IV-M-2 Interest, are referred to herein as the “Subsidiary REMIC 2 Accretion Directed Classes” and together with the LT-Accrual Interest, the “Subsidiary REMIC 2 Regular Interests”) and the R-2 Interest as the single “residual interest” in Subsidiary REMIC 2.

The Master REMIC will consist of the Subsidiary REMIC 1b and REMIC 2 Regular Interests and will be evidenced by the Class I-A-1 Interest, Class I-AS Interest, Class II-A-1 Interest, Class II-A-2 Interest, Class II-AS Interest, Class C-B-1 Interest, Class C-B-2 Interest, Class C-B-3 Interest, Class C-B-4 Interest, Class C-B-5 Interest, Class C-B-6 Interest, Class III-A-1 Interest, Class IV-A-1 Interest, Class IV-M-1 Interest, Class IV-M-2 Interest, Class II-X Interest and Class IV-X (which will represent the “regular interests” in the Master REMIC) and the R-3 Interest as the single “residual interest” in the Master REMIC. The Class AR Certificates will represent beneficial ownership of the R-1a Interest, the R-1b Interest, the R-2 Interest and the R-3 Interest.

The “latest possible maturity date” for federal income tax purposes of all interests created hereby will be the Latest Possible Maturity Date (as defined in Section 11.01 herein).

Subsidiary REMIC 1A:

The Subsidiary REMIC 1A Regular Interests, each of which is hereby designated a REMIC regular interest for federal income tax purposes, shall have the following principal balances, pass-through rates and Corresponding Classes of Certificates in the manner set forth in the following table:

REMIC Interests	Initial Balance	Pass- Through Rate	Corresponding Loan Group
LT1-I	(1)	(2)	I
LT2-I	(1)	(2)	I
LT3-I	(1)	(2)	I
LT1-II	(1)	(2)	II
LT2-II	(1)	(2)	II
LT3-II	(1)	(2)	II
LT1-III	(1)	(2)	III
LT2-III	(1)	(2)	III
LT3-III	(1)	(2)	III
LT-AS-1	(3)	0.02%	I
LT-AS-2	(3)	0.02%	II
LT-AS-3	(3)	0.02%	III

__________________

Each LT1 Interest shall have a principal balance initially equal to 0.9% of the Subordinate Component Balance of its Corresponding Loan Group. Each LT2 Interest shall have a principal balance initially equal to 0.1% of the Subordinate Component Balance of its Corresponding Loan Group. The initial Subordinate Component Balance for each Loan Group shall equal the excess of the Loan Group as of the Cut-off Date over the initial balance of corresponding Class A Certificates. The initial principal balance of each LT3 Interest shall equal the excess of its corresponding Loan Group over the initial principal balances of the LT1 and LT2 Interests corresponding to such Loan Group.

For each Distribution Date, a per annum rate equal to the weighted average Net Mortgage Rates as of the second preceding Due Date for the Mortgage Loans (excluding any such Mortgage Loans that were subject to a Payoff, the principal of which was distributed on the Distribution Date preceding the current Distribution Date) of the Corresponding Loan Group less 0.02% per annum.

These interests shall not have a principal balance but shall have a notional amount equal to the principal balance of its corresponding Loan Group as of the beginning of the Due Period for such Distribution Date.

Unless a Cross-over Situation exists, Principal Reductions arising with respect to each Loan Group shall be allocated first to cause the LT1 and LT 2 Interests corresponding to such Loan Group to equal 0.9% and 0.1% respectively of the Subordinate Component Balance as of such Distribution Date (determined as the excess of the Loan Group as of the end of the Accrual Period in excess of such Loan Group’s related Class A Certificates after taking into account principal distributions to the Class A Certificates on such Distribution Date) of such Loan Group and all excess Principal Reductions shall be allocated to the LT3 Interest corresponding to such Loan Group. A Principal Reduction is Principal Payment (including Servicer Advances of Principal Payments, if any) from the Mortgage Loans in the related Loan Group and a Realized Loss from the Mortgage Loans in the related Loan Group. Principal Reductions shall consist proportionately of Principal Payments and Realized Losses and an Interest allocated a Principal Payment shall receive such Principal Payment on such Distribution Date and shall have its principal balance reduced by an allocation of Realized Losses. A Cross-Over Situation exists if on any Distribution Date (after taking into account principal distributions on such Distribution Date) the LT1 and LT2 Interests corresponding to any Loan Group are in the aggregate less than 1% of the Subordinate Component Balance of the Loan Group to which they correspond. In the event that a Cross-Over Situation exists on any Distribution Date, and the weighted average rate of the outstanding LT1 and LT2 interests is less than the Pass-Through Rate for the Class C-B Certificates, a Principal Relocation Payment shall be made proportionately to the outstanding LT1 Interests prior to any other Principal Distributions from each such Loan Group. In the event that a Cross-Over Situation exists on any Distribution Date, and the weighted average rate of the outstanding LT1 and LT2 interests is greater than the Pass-Through Rate for the Class C-B Certificates, a Principal Relocation Payment shall be made proportionately to the outstanding LT2 Interests prior to any other Principal Distributions from each such Loan Group. A Principal Relocation Payment shall be made so as to cause the Calculation Rate on the outstanding LT1 and LT2 Interests to equal the Pass-Through Rate for the Class C-B Certificate. The Calculation Rate shall equal the product of (i) 10 and (ii) the weighted average rate of the outstanding Class LT1 and Class LT2 Interests, treating each Class LT1 Interest as capped at zero or reduced by a fixed percentage of 100% of the interest accruing on such Class. Principal Relocation Payments shall be made from Principal Payments received on the Mortgage Loans from a Loan Group and shall also consist of a proportionate allocation of Realized Losses from the Mortgage Loans of a Loan Group. For purposes of making Principal Relocation Payments, to the extent that the Principal Payments received during the Accrual Period from the related Loan Group (including advances of Principal Payments, if any, by the Servicer) and Realized Losses are insufficient to make the necessary reduction of principal, then interest shall accrue on the Loan Group’s related LT Interest (and be added to their principal balances) that are not receiving a Principal Relocation Payment to allow the necessary Principal Relocation Payment to be made.

If a Cross-Over Situation exists, the outstanding aggregate LT1 and LT2 Interests shall not be reduced below 1 percent of the aggregate outstanding Principal Balances of the Loan Groups as of the end of any Accrual Period in excess of the Class A Certificates as of the related Distribution Date (after taking into account distributions of principal on such Distribution Date). To the extent this limitation prevents the distribution of principal to the LT1 and LT2 Interests of a Loan Group and the related LT3 Interest has already been reduced to zero, such excess principal from the other Loan Group or Loan Groups shall be paid proportionately to the LT3 Interests of the Loan Groups whose aggregate LT1 and LT2 Interests are less than one percent of the Subordinate Component Balance. Any such shortfall as result of the Loan Group receiving the extra payment having a Net WAC Rate lower than the Loan Group from which the payment was relocated shall be treated as a Realized Loss and if excess arises as result of the Loan Group receiving the extra payment having a Net WAC Rate higher than the Loan Group from which the payment was relocated it shall reimburse Subsidiary REMIC 1B for prior Realized Losses. If on any Distribution Date, the LT1 Interest or LT2 Interest remains outstanding after the principal balance on their corresponding Mortgage Loans is at zero as of the beginning of the Accrual Period corresponding to such Distribution Date, their Pass-Through Rate shall be the Net WAC Rate of the Loan Group with the lowest Net WAC Rate that remains outstanding and the excess of the Pass-Through Rate for the C-B classes and such Net WAC Rate shall be treated as paid from Subsidiary REMIC 1A to Subsidiary REMIC 1B as reimbursement for prior Realized Losses.

Subsidiary REMIC 1B:

The Subsidiary REMIC 1B Regular Interests, each of which is hereby designated a REMIC regular interest for federal income tax purposes, shall have the following principal balances, and pass-through rates of Certificates in the manner set forth in the following table:

Subsidiary REMIC 1B Interests	Initial Balance	Pass- Through Rate	Corresponding Loan Group
LT-I-A-1	$107,293,000	(1)	I
LT-I-AR	$100	(1)	I
LT-II-A-1	$315,985,000	(1)	II
LT-II-A-2	$6,320,000	(1)	II
LT-III-A-1	$39,435,500	(1)	III
LT-AS-1	(3)	0.02%	I
LT-AS-2	(3)	0.02%	II
LT-AS-3	(3)	0.02%	III
LT-C-B-1	$8,640,500	(2)	I , II and III
LT-C-B-2	$6,171,600	(2)	I, II and III
LT-C-B-3	$4,196,700	(2)	I, II and III
LT-C-B-4	$2,962,350	(2)	I, II and III
LT-C-B-5	$1,481,200	(2)	I, II and III
LT-C-B-6	$1,234,314	(2)	I, II and III

_______________

The Calculation Rate, which per annum rate equals the product of (i) 10 and (ii) the weighted average rate of the outstanding Class LT1 and Class LT2 Interests, treating each Class LT1 Interest as capped at zero or reduced by a fixed percentage of 100% of the interest accruing on such Class. The Calculation Rate is designed to always equal the Pass Through Rate of the Class C-B Certificates.

Each Subsidiary REMIC 1B Regular Interests shall receive principal distributions and allocations of Realized Losses equal to those for its corresponding class in the Master REMIC.

Subsidiary REMIC 2:

The Subsidiary REMIC 2 Regular Interests, each of which is hereby designated a REMIC regular interest for federal income tax purposes, shall have the following principal balances, pass-through rates and Corresponding Classes of Certificates in the manner set forth in the following table:

REMIC Interests	Initial Balance	Pass- Through Rate	Corresponding Class of Master REMIC Interest
LT-IV-A-1	1/2 Corresponding Master Class balance	(1)	IV-A-1
LT-IV-M-1	1/2 Corresponding Master Class balance	(1)	IV-M-1
LT-IV-M-2	1/2 Corresponding Master Class balance	(1)	IV-M-2
LT–Accrual Interest	1/2 Loan Group IV Mortgage Pool balance plus 1/2 Overcollateralization Amount on Closing Date	(1)	X/X
X-0	X/X	X/X	X/X

_______________

(1)

A Rate equal to the Net Funds Cap (excluding any such Mortgage Loans that were subject to a Payoff, the principal of which was distributed on the Distribution Date preceding the current Distribution Date).

On each Distribution Date, 50% of the increase in the Overcollateralization Amount will be payable as a reduction of the principal balances of the Subsidiary REMIC 2 Accretion Directed Classes (each such Class will be reduced by an amount equal to 50% of any increase in the Overcollateralization Amount that is attributable to a reduction in the principal balance of its Corresponding Class) and will be accrued and added to the principal balance of the LT-Accrual Interest. All payments of scheduled principal and prepayments of principal generated by the Mortgage Loans shall be allocated 50% to the LT-Accrual Interest, and 50% to the Subsidiary REMIC 2 Accretion Directed Classes (principal payments shall be allocated among such Subsidiary REMIC 2 Accretion Directed Classes in an amount equal to 50% of the principal amounts allocated to their respective Corresponding Classes), until paid in full. In the event that: (i) 50% of the increase in the Overcollateralization Amount exceeds (ii) interest accruals on the Subsidiary REMIC 2 Interest for such Distribution Date, the excess for such Distribution Date (accumulated with all such excesses for all prior Distribution Dates) will be added to any increase in the Overcollateralization Amount for purposes of determining the amount of interest accrual on the Subsidiary REMIC 2 Interest payable as principal on the Subsidiary REMIC 2 Accretion Directed Classes on the next Distribution Date pursuant to the first sentence of this paragraph. Notwithstanding the above, principal payments allocated to the Class IV-X Certificates that result in the reduction in the Overcollateralization Amount shall be allocated to the LT-Accrual Interest (until paid in full). Realized losses shall be applied so that after all distributions have been made on each Distribution Date the principal balances of each of the Subsidiary REMIC 2 Accretion Directed Classes is equal to 50% of the principal balance of their Corresponding Class, and the Subsidiary REMIC 2 Accrual Class is equal to 50% of the Aggregate Loan Group Balance of the Group IV Mortgage Loans plus 50% of the Overcollateralization Amount.

The foregoing allocations are intended to cause the LT-IV-A-1 Interest, LT-IV-M-1 Interest and LT-IV-M-2 Interest to equal 50% of their corresponding Classes and to cause the LT-Accrual Interest Principal Balance to equal the Aggregate Loan Group Balance of the Group IV Mortgage Loans, as of the beginning of each Collection Period (excluding any principal payments included in such Aggregate Loan Group Balance distributed on the Distribution Date occurring during such Collection Period), less the aggregate Class Principal Balance of the Class IV-A-1, Class IV-M-1 and Class IV-M-2 Certificates, as of the beginning of such Accrual Period.

Master REMIC:

The following table sets forth characteristics of the Certificates, each of which, except for the Class R-3 Interests (and the right to receive Basis Risk Carryforward, in the case of the Class IV-A-1, Class IV-M-1 and Class IV-M-2), is hereby designated as a “regular interest” in the Master REMIC, together with the minimum denominations and integral multiples in excess thereof in which such Classes shall be issuable (except that one Certificate of each Class of Certificates may be issued in a different amount and, in addition, one Residual Certificate representing the Tax Matters Person Certificate may be issued in a different amount):

	Class Principal Balance	Pass-Through Rate (per annum)	Minimum Denomination	Integral Multiples in Excess of Minimum

The foregoing REMIC structure is intended to cause all of the cash from the Mortgage Loans to flow through to the Master REMIC as cash flow on a REMIC regular interest, without creating any shortfall—actual or potential (other than for credit losses) to any REMIC regular interest. To the extent that the structure is believed to diverge from such intention the Trust Administrator shall resolve ambiguities to accomplish such result and shall to the extent necessary rectify any drafting errors or seek clarification to the structure without Certificateholder approval (but with guidance of counsel) to accomplish such intention.

In the event the Depositor delivers to the Trustee or the Custodian certified copies of any document or instrument set forth in 2.01(b) because of a delay caused by the public recording office in returning any recorded document, the Depositor shall deliver or cause to be delivered to the Trustee or the Custodian, within 60 days of the Closing Date, an Officer’s Certificate which shall (i) identify the recorded document, (ii) state that the recorded document has not been delivered to the Trustee or the Custodian due solely to a delay caused by the public recording office, and (iii) state the amount of time generally required by the applicable recording office to record and return a document submitted for recordation.

In the event that in connection with any Mortgage Loan the Depositor cannot deliver (a) the original recorded Mortgage, (b) all interim recorded assignments or (c) the lender’s title policy (together with all riders thereto) satisfying the requirements set forth above, concurrently with the execution and delivery hereof because such document or documents have not been returned from the applicable public recording office in the case of clause (a) or (b) above, or because the title policy has not been delivered to the related Seller or the Depositor by the applicable title insurer in the case of clause (c) above, the Depositor shall promptly deliver to the Trustee or the Custodian, in the case of clause (a) or (b) above, such original Mortgage or such interim assignment, as the case may be, with evidence of recording indicated thereon upon receipt thereof from the public recording office, or a copy thereof, certified, if appropriate, by the relevant recording office and, in the case of clause (c) above, any title policy upon receipt from the applicable title insurer.

As promptly as practicable subsequent to such transfer and assignment, and in any event, within thirty (30) days thereafter, DLJMC shall, at its expense, (i) affix or cause to be affixed the Trustee’s name to each Assignment of Mortgage, as the assignee thereof, (ii) cause such assignment to be in proper form for recording in the appropriate public office for real property records within thirty (30) days after receipt thereof and (iii) cause to be delivered for recording in the appropriate public office for real property records the assignments of the Mortgages to the Trustee, except that, with respect to any assignment of a Mortgage as to which DLJMC has not received the information required to prepare such assignment in recordable form, DLJMC’s obligation to do so and to deliver the same for such recording shall be as soon as practicable after receipt of such information and in any event within thirty (30) days after the receipt thereof, and DLJMC need not cause to be recorded any assignment which relates to a Mortgage Loan in any jurisdiction under the laws of which, as evidenced by an Opinion of Counsel delivered by the Depositor (at the Depositor’s expense) to the Trustee, the Trust Administrator and DLJMC, acceptable to the Rating Agencies, the recordation of such assignment is not necessary to protect the Trustee’s and the Certificateholders’ interest in the related Mortgage Loan.

If any original Mortgage Note referred to in Section 2.01(b)(i) above cannot be located, the obligations of the Depositor to deliver such documents shall be deemed to be satisfied upon delivery to the Trustee or the Custodian of a photocopy of such Mortgage Note, if available, with a lost note affidavit and indemnity. If any of the original Mortgage Notes for which a lost note affidavit and indemnity was delivered to the Trustee or the Custodian is subsequently located, such original Mortgage Note shall be delivered to the Trustee or the Custodian within three Business Days.

(c)

The Trustee is authorized to appoint any bank or trust company approved by the Depositor as Custodian of the documents or instruments referred to in this Section 2.01, and to enter into a Custodial Agreement for such purpose and any documents delivered thereunder shall be delivered to the Custodian and any Officer’s Certificates delivered with respect thereto shall be delivered to the Trustee and the Custodian.

(d)

It is the express intent of the parties to this Agreement that the conveyance of the Mortgage Loans by the Depositor to the Trustee as provided in this Section 2.01 be, and be construed as, a sale of the Mortgage Loans by the Depositor to the Trustee. It is, further, not the intention of the parties to this Agreement that such conveyance be deemed a pledge of the Mortgage Loans by the Depositor to the Trustee to secure a debt or other obligation of the Depositor. However, in the event that, notwithstanding the intent of the parties to this Agreement, the Mortgage Loans are held to be the property of the Depositor, or if any for any other reason this Agreement is held or deemed to create a security interest in the Mortgage Loans then (a) this Agreement shall also be deemed to be a security agreement within the meaning of Articles 8 and 9 of the New York Uniform Commercial Code; (b) the conveyance provided for in this Section 2.01 shall be deemed to be a grant by the Depositor to the Trustee for the benefit of the Certificateholders of a security interest in all of the Depositor’s right, title and interest in and to the Mortgage Loans and all amounts payable to the holders of the Mortgage Loans in accordance with the terms thereof and all proceeds of the conversion, voluntary or involuntary, of the foregoing into cash, instruments, securities or other property, including without limitation all amounts, other than investment earnings, from time to time held or invested in the Certificate Account, whether in the form of cash, instruments, securities or other property; (c) the possession by the Trustee or any Custodian of such items of property and such other items of property as constitute instruments, money, negotiable documents or chattel paper shall be deemed to be “in possession by the secured party” for purposes of perfecting the security interest pursuant to Section 9 313 of the New York Uniform Commercial Code; and (d) notifications to persons holding such property, and acknowledgments, receipts or confirmations from persons holding such property, shall be deemed notifications to, or acknowledgments, receipts or confirmations from, financial intermediaries, bailees or agents (as applicable) of the Trustee for the benefit of the Certificateholders for the purpose of perfecting such security interest under applicable law (except that nothing in this clause (d) shall cause any person to be deemed to be an agent of the Trustee for any purpose other than for perfection of such security interests unless, and then only to the extent, expressly appointed and authorized by the Trustee in writing). The Depositor and the Trustee, upon directions from the Depositor, shall, to the extent consistent with this Agreement, take such actions as may be necessary to ensure that, if this Agreement were deemed to create a security interest in the Mortgage Loans, such security interest would be deemed to be a perfected security interest of first priority under applicable law and will be maintained as such throughout the term of this Agreement.

SECTION 2.02

Acceptance by the Trustee.

(a)

The Trustee acknowledges receipt of the documents identified in the Trust Receipt and Initial Certification in the form annexed hereto as Exhibit I and declares that it holds and will hold such documents and the other documents delivered to it constituting the Mortgage Files, and that it holds or will hold such other assets as are included in the Trust Fund, in trust for the exclusive use and benefit of all present and future Certificateholders. The Trustee acknowledges that it will maintain possession of the Mortgage Notes in the State of Illinois or the State of Texas, unless otherwise permitted by the Rating Agencies.

The Trustee or the Custodian agrees to execute and deliver on the Closing Date to the Depositor, the Master Servicer, each Seller, each Servicer and the Trust Administrator a Trust Receipt and Initial Certification in the form annexed hereto as Exhibit I. Based on its review and examination, and only as to the documents identified in such Trust Receipt and Initial Certification, the Trustee or the Custodian acknowledges that such documents appear regular on their face and relate to such Mortgage Loan. The Trustee or the Custodian shall be under no duty or obligation to inspect, review or examine said documents, instruments, certificates or other papers to determine that the same are genuine, enforceable or appropriate for the represented purpose or that they have actually been recorded in the real estate records or that they are other than what they purport to be on their face.

Not later than 90 days after the Closing Date, the Trustee or the Custodian shall deliver to the Depositor, the Master Servicer, each Seller and Servicer and the Trust Administrator a Trust Receipt and Final Certification in the form annexed hereto as Exhibit J, with any applicable exceptions noted thereon.

The Trust Administrator, on behalf of the Trustee, acknowledges receipt of the Initial Cash Deposit Amount referred to in Section 2.01 above and shall (i) deposit such Initial Cash Deposit Amount into the Certificate Account as part of the Available Distribution Amount for the initial Distribution Date and (ii) declare that it holds and will hold such Initial Cash Deposit Amount for the exclusive use and benefit of the Certificateholders.

Subject to the provisions of Section 2.01 and subject to any exceptions noted on the exception report described in the next paragraph below, the Trustee acknowledges receipt of the documents referred to in Section 2.01 above and declares that it holds and will hold such documents and the other documents delivered to it constituting the Mortgage File, and that it holds or will hold all such assets and such other assets included in the definition of the Trust Fund in trust for the exclusive use and benefit of all present and future Certificateholders.

If, in the course of such review, the Trustee or the Custodian finds any document constituting a part of a Mortgage File which does not meet the requirements of Section 2.01, the Trustee or the Custodian shall list such as an exception in the Trust Receipt and Final Certification; provided, however, that the Trustee or the Custodian shall not make any determination as to whether (i) any endorsement is sufficient to transfer all right, title and interest of the party so endorsing, as noteholder or assignee thereof, in and to that Mortgage Note or (ii) any assignment is in recordable form or is sufficient to effect the assignment of and transfer to the assignee thereof under the mortgage to which the assignment relates.

With respect to each Mortgage Loan for which it is the Seller, each Seller shall promptly correct or cure such defect within 90 days from the date it was so notified of such defect and, if such Seller does not correct or cure such defect within such period, such Seller shall either (a) substitute for the related Mortgage Loan a Qualified Substitute Mortgage Loan, which substitution shall be accomplished in the manner and subject to the conditions set forth in Section 2.03, or (b) purchase such Mortgage Loan from the Trustee or the Custodian within 90 days from the date that the related Seller was notified of such defect in writing at the Purchase Price of such Mortgage Loan; or such longer period not to exceed 720 days from the Closing Date if the substitution or repurchase of a Mortgage Loan pursuant to this provision is required by reason of a delay in delivery of any documents by the appropriate recording office; provided, however, that a Seller shall have no liability for recording any Assignment of Mortgage in favor of the Trustee or for the Trustee’s failure to record such Assignment of Mortgage, and provided, further, that no Seller shall be obligated to repurchase or cure any Mortgage Loan solely as a result of the Trustee’s failure to record such Assignment of Mortgage. The Trustee shall deliver written notice to each Rating Agency within 270 days from the Closing Date indicating each Mortgage Loan (a) for which a mortgage or assignment of mortgage required to be recorded hereunder has not been returned by the appropriate recording office or (b) as to which there is a dispute as to location or status of such Mortgage Loan. Such notice shall be delivered every 90 days thereafter until the related Mortgage Loan is returned to the Trustee. Any such substitution pursuant to (a) above or purchase pursuant to (b) above shall not be effected prior to the delivery to the Trustee and the Trust Administrator of the Opinion of Counsel required by Section 2.05 hereof, if any, and any substitution pursuant to (a) above shall not be effected prior to the additional delivery to the Trustee or the Trust Administrator of a Request for Release substantially in the form of Exhibit K. No substitution is permitted to be made in any calendar month after the Determination Date for such month. The Purchase Price for any such Mortgage Loan shall be deposited by the related Seller in the Certificate Account on or prior to the Business Day immediately preceding such Distribution Date in the month following the month of repurchase and, upon receipt of such deposit and certification with respect thereto in the form of Exhibit K hereto, the Trustee or the Custodian shall release the related Mortgage File to the related Seller and shall execute and deliver at such entity’s request such instruments of transfer or assignment prepared by such entity, in each case without recourse, as shall be necessary to vest in such entity, or a designee, the Trustee’s interest in any Mortgage Loan released pursuant hereto.

(b)

It is understood and agreed that the obligation of each Seller to cure, substitute for or to repurchase any Mortgage Loan which does not meet the requirements of Section 2.01 shall constitute the sole remedy respecting such defect available to the Trustee, the Trust Administrator, the Depositor and any Certificateholder against the Sellers.

SECTION 2.03

Representations and Warranties of the Sellers, Master Servicer and Servicers.

(a)

Each of DLJMC, in its capacity as Seller, CMMC, in its capacity as Master Servicer, WMMSC, in its capacity as Seller and Servicer, Fairbanks, in its capacity as Servicer and Special Servicer, WMBFA, in its capacity as Seller and Servicer and WMB in its capacity as Seller, hereby makes the representations and warranties applicable to it set forth in Schedule IIA, IIB, IIC, IID, IIE or IIF, as applicable hereto, and by this reference incorporated herein, to the Depositor, the Trustee and the Trust Administrator, as of the Closing Date, or if so specified therein, as of the Cut off Date or such other date as may be specified. In addition, each of Fairbanks, in its capacity as Servicer and Special Servicer and WMBFA, in its capacity as Servicer, makes the representations and warranties applicable to it set forth in Schedule IID and Schedule IIE hereto, respectively, and by this reference incorporated herein, to the Master Servicer as of the Closing Date, or if so specified therein, as of the Cut off Date or such other date as may be specified.

(b)

Each of DLJMC, in its capacity as Seller, WMMSC, in its capacity as Seller, WMBFA, in its capacity as Seller and WMB, in its capacity as Seller, hereby makes the representations and warranties set forth in Schedule IIIA, IIIB, IIIC and IIID, respectively, as to the DLJMC Mortgage Loans, the WMMSC Mortgage Loans, the WMBFA Mortgage Loans and the WMB Mortgage Loans respectively, and by this reference incorporated herein, to the Depositor, the Trustee and the Trust Administrator, as of the Closing Date, or if so specified therein, as of the Cut off Date or such other date as may be specified. Any breach of the representations and warranties set forth in Schedule IIIA(xix), IIIA(xxiv) and IIIB(xxiii) shall be deemed to materially and adversely affect the interests of the Certificateholders in that Mortgage Loan, notwithstanding the related Seller’s lack of knowledge with respect to the substance of such representation and warranty

(c)

Upon discovery by any of the parties hereto of a breach of a representation or warranty made pursuant to Section 2.03(b) that materially and adversely affects the interests of the Certificateholders in any Mortgage Loan, the party discovering such breach shall give prompt notice thereof to the other parties; provided that, if applicable, any breach of the warranties and representations set forth in Schedule IIIA(xix) shall be deemed to materially and adversely affect the interests of the Certificateholders in that Mortgage Loan. Each Seller hereby covenants that within 90 days of the earlier of its discovery or its receipt of written notice from any party of a breach of any representation or warranty made by it pursuant to Section 2.03(b) which materially and adversely affects the interests of the Certificateholders in any Mortgage Loan sold by such Seller to the Trust, it shall cure such breach in all material respects, and if such breach is not so cured, shall, (i) if such 90 day period expires prior to the second anniversary of the Closing Date, remove such Mortgage Loan (a “Deleted Mortgage Loan”) from the Trust Fund and substitute in its place a Qualified Substitute Mortgage Loan, in the manner and subject to the conditions set forth in this Section; or (ii) repurchase the affected Mortgage Loan or Mortgage Loans from the Trustee at the Purchase Price in the manner set forth below; provided, however, that any such substitution pursuant to (i) above shall not be effected prior to the delivery to the Trustee and the Trust Administrator of the Opinion of Counsel required by Section 2.05 hereof, if any, and any such substitution pursuant to (i) above shall not be effected prior to the additional delivery to the Trustee or the Trust Administrator of a Request for Release substantially in the form of Exhibit K relating to the Deleted Mortgage Loan and the Mortgage File for any such Qualified Substitute Mortgage Loan. The related Seller shall promptly reimburse the Trustee, the Trust Administrator, the Special Servicer and the related Servicer (if such Servicer is not the Seller of such Mortgage Loan) for any actual out of pocket expenses reasonably incurred by the Trustee, the Trust Administrator, the Special Servicer and the related Servicer (if such Servicer is not the Seller of such Mortgage Loan) in respect of enforcing the remedies for such breach. With respect to any representation and warranties described in this Section which are made to the best of a Seller’s knowledge if it is discovered by any of the Depositor, the Master Servicer, any Seller, any Servicer, the Special Servicer, the Trustee or the Trust Administrator that the substance of such representation and warranty is inaccurate and such inaccuracy materially and adversely affects the value of the related Mortgage Loan or the interests of the Certificateholders therein, notwithstanding the related Seller’s lack of knowledge with respect to the substance of such representation or warranty, such inaccuracy shall be deemed a breach of the applicable representation or warranty.

With respect to any Qualified Substitute Mortgage Loan or Loans, the related Seller shall deliver to the Trustee for the benefit of the Certificateholders the Mortgage Note, the Mortgage, the related assignment of the Mortgage, and such other documents and agreements as are required by Section 2.01(b), with the Mortgage Note endorsed and the Mortgage assigned as required by Section 2.01. No substitution is permitted to be made in any calendar month after the Determination Date for such month. Scheduled Payments due with respect to Qualified Substitute Mortgage Loans in the month of substitution shall not be part of the Trust Fund and will be retained by such Seller on the next succeeding Distribution Date. For the month of substitution, distributions to Certificateholders will include the monthly payment due on any Deleted Mortgage Loan for such month and thereafter the related Seller shall be entitled to retain all amounts received in respect of such Deleted Mortgage Loan. The related Seller shall amend the Mortgage Loan Schedule for the benefit of the Certificateholders to reflect the removal of such Deleted Mortgage Loan and the substitution of the Qualified Substitute Mortgage Loan or Loans and the related Seller shall deliver the amended Mortgage Loan Schedule to the Trustee, the Servicers and the Trust Administrator. Upon such substitution, the Qualified Substitute Mortgage Loan or Loans shall be subject to the terms of this Agreement in all respects, and the related Seller shall be deemed to have made with respect to such Qualified Substitute Mortgage Loan or Loans, as of the date of substitution, the representations and warranties made pursuant to Section 2.03(b) with respect to such Mortgage Loan. Upon any such substitution and the deposit to the Collection Account of the amount required to be deposited therein in connection with such substitution as described in the following paragraph, the Trustee or the Custodian, as applicable, shall release the Mortgage File held for the benefit of the Certificateholders relating to such Deleted Mortgage Loan to such Seller and shall execute and deliver at the related Seller’s direction such instruments of transfer or assignment prepared by such Seller, in each case without recourse, as shall be necessary to vest title in such Seller, or its designee, the Trustee’s interest in any Deleted Mortgage Loan substituted for pursuant to this Section 2.03.

For any month in which a Seller substitutes one or more Qualified Substitute Mortgage Loans for one or more Deleted Mortgage Loans, the Master Servicer, or WMMSC if such Deleted Mortgage Loan is a WMMSC Serviced Mortgage Loan, shall determine the amount (if any) by which the aggregate principal balance of all such Qualified Substitute Mortgage Loans as of the date of substitution is less than the aggregate Stated Principal Balance of all such Deleted Mortgage Loans (after application of the scheduled principal portion of the monthly payments due in the month of substitution). The amount of such shortage (the “Substitution Adjustment Amount”) plus an amount equal to the aggregate of any unreimbursed Advances, Servicing Advances and unpaid Servicing Fees with respect to such Deleted Mortgage Loans shall be deposited in the Collection Account by the related Seller on or before the Business Day immediately preceding the Distribution Date in the month succeeding the calendar month during which the related Mortgage Loan became required to be repurchased or replaced hereunder.

One or more mortgage loans may be substituted for one or more Deleted Mortgage Loans. The determination of whether a mortgage loan is a Qualified Substitute Mortgage Loan may be satisfied on an individual basis. Alternatively, if more than one mortgage loan is to be substituted for one or more Deleted Mortgage Loans, the characteristics of such mortgage loans and Deleted Mortgage Loans shall be aggregated or calculated on a weighted average basis, as applicable, in determining whether such mortgage loans are Qualified Substitute Mortgage Loans.

In the event that a Seller shall have repurchased a Mortgage Loan, the Purchase Price therefor shall be deposited in the Collection Account on or before the Business Day immediately preceding the Distribution Date in the month following the month during which such Seller became obligated hereunder to repurchase or replace such Mortgage Loan and upon such deposit of the Purchase Price, the delivery of the Opinion of Counsel if required by Section 2.05 and receipt of a Request for Release in the form of Exhibit K hereto, the Trustee, the Trust Administrator or the Custodian, as applicable, shall release the related Mortgage File held for the benefit of the Certificateholders to such Person, and the Trustee shall execute and deliver at such Person’s direction such instruments of transfer or assignment prepared by such Person, in each case without recourse, as shall be necessary to transfer title from the Trustee. It is understood and agreed that the obligation under this Agreement of any Person to cure, repurchase or substitute any Mortgage Loan as to which a breach has occurred and is continuing shall constitute the sole remedy against such Persons respecting such breach available to Certificateholders, the Depositor, the Trustee or the Trust Administrator on their behalf.

The representations and warranties made pursuant to this Section 2.03 shall survive delivery of the respective Mortgage Files to the Trustee, the Trust Administrator or the Custodian for the benefit of the Certificateholders.

Notwithstanding the foregoing, the substitution of a Deleted Mortgage Loan that is a WMMSC Serviced Mortgage Loan or a WMBFA Serviced Mortgage Loan or the repurchase of a Mortgage Loan that is a WMMSC Serviced Mortgage Loan or a WMBFA Serviced Mortgage Loan by a Seller shall be subject to, and shall in no way adversely affect, the right of WMMSC or WMBFA, respectively, to continue servicing and collecting its Servicing Fee for such Deleted Mortgage Loan or Mortgage Loan, as applicable.

SECTION 2.04

Representations and Warranties of the Depositor as to the Mortgage Loans.

The Depositor hereby represents and warrants to the Trustee with respect to the Mortgage Loans that, as of the Closing Date, assuming good title has been conveyed to the Depositor, the Depositor had good title to the Mortgage Loans and Mortgage Notes, and did not encumber the Mortgage Loans during its period of ownership thereof, other than as contemplated by the Agreement.

It is understood and agreed that the representations and warranties set forth in this Section 2.04 shall survive delivery of the Mortgage Files to the Trustee.

SECTION 2.05

Delivery of Opinion of Counsel in Connection with Substitutions.

Notwithstanding any contrary provision of this Agreement, no substitution pursuant to Section 2.02 shall be made more than 90 days after the Closing Date unless the related Seller delivers to the Trustee and the Trust Administrator an Opinion of Counsel, which Opinion of Counsel shall not be at the expense of any of the Trustee, the Trust Administrator or the Trust Fund, addressed to the Trustee and the Trust Administrator, to the effect that such substitution will not (i) result in the imposition of the tax on “prohibited transactions” on the Trust Fund or contributions after the Startup Date, as defined in Sections 860F(a)(2) and 860G(d) of the Code, respectively, or (ii) cause each REMIC created hereunder to fail to qualify as a REMIC at any time that any Certificates are outstanding.

SECTION 2.06

Issuance of Certificates.

The Trustee acknowledges the assignment to it of the Mortgage Loans together with the assignment to it of all other assets included in the Trust Fund, receipt of which is hereby acknowledged. Concurrently with such assignment and delivery and in exchange therefor, the Trust Administrator, pursuant to the written request of the Depositor executed by an officer of the Depositor, has executed the Certificates and caused them to be authenticated and delivered to or upon the order of the Depositor in authorized denominations which evidence ownership of the Trust Fund. The rights of the Holders of such Certificates to receive distributions from the Trust Fund and all ownership interests of the Holders of the Certificates in such distributions shall be as set forth in this Agreement.

SECTION 2.07

REMIC Provisions.

(a)

The Depositor hereby elects and authorizes the Trust Administrator to treat the Trust Fund as the number of separate REMICs specified in the Preliminary Statement (each, a “REMIC”) under the Code and, if necessary, under applicable state law and apply such Preliminary Statement in determining the rights of the Interests in REMICs thereby created. Each such election will be made on Form 1066 or other appropriate federal tax or information return (including Form 8811) or any appropriate state return (x) for the taxable year ending on the last day of the calendar year in which the Certificates are issued and (y) for the taxable year ending on the last day of the calendar year in which Certificates are first sold to a third party. The Closing Date is hereby designated as the “startup day” of each REMIC created hereunder within the meaning of Section 860G(a)(9) of the Code. The “regular interests” (within the meaning of Section 860G of the Code) in each REMIC shall consist of the regular interests with the terms set forth for each REMIC in the Preliminary Statement and the Class AR Certificates shall represent the beneficial ownership of the “residual interest” in each REMIC created hereunder. Neither the Depositor nor the Trust Administrator nor the Trustee shall permit the creation of any “interests” (within the meaning of Section 860G of the Code) in any REMIC other than as set forth in the Preliminary Statement.

(b)

The Trust Administrator on behalf of the Holders of the Class AR Certificates, shall act as agent for the Class AR Certificateholder as the “tax matters person” (within the meaning of the REMIC Provisions) for each REMIC created hereunder, in the manner provided under Treasury regulations section 1.860F 4(d) and temporary Treasury regulations section 301.6231(a)(7) 1T. By its acceptance of a Class AR Certificate, each Holder thereof shall have agreed to such appointment and shall have consented to the appointment of the Trust Administrator as its agent to act on behalf of each REMIC created hereunder pursuant to the specific duties outlined herein.

(c)

A Holder of the Class AR Certificates, by the purchase of such Certificates, shall be deemed to have agreed to timely pay, upon demand by the Trust Administrator, the amount of any minimum California state franchise taxes due with respect to each REMIC created hereunder under Sections 23151(a) and 23153(a) of the California Revenue and Taxation Code. Notwithstanding the foregoing, the Trust Administrator shall be authorized to retain the amount of such tax from amounts otherwise distributable to such Holder in the event such Holder does not promptly pay such amount upon demand by the Trust Administrator. In the event that any other federal, state or local tax is imposed, including without limitation taxes imposed on a “prohibited transaction” of a REMIC as defined in Section 860F of the Code, such tax shall be charged against amounts otherwise available for distribution to the applicable Holder of a Class AR Certificate and then against amounts otherwise available for distribution to the Holders of Regular Certificates in accordance with the provisions set forth in Section 4.01. The Trust Administrator or the Trustee shall promptly deposit in the Certificate Account any amount of “prohibited transaction” tax that results from a breach of the Trust Administrator’s or the Trustee’s duties, respectively, under this Agreement. The Master Servicer or the related Servicer shall promptly deposit in the Certificate Account any amount of “prohibited transaction” tax that results from a breach of the Master Servicer’s or such Servicer’s duties, respectively, under this Agreement.

(d)

The Trust Administrator shall act as attorney in fact and as agent on behalf of the tax matters person of each REMIC created hereunder and in such capacity the Trust Administrator shall: (i) prepare, sign and file, or cause to be prepared, signed and filed, federal and state tax returns using a calendar year as the taxable year for each REMIC created hereunder when and as required by the REMIC Provisions and other applicable federal income tax laws as the direct representative of each such REMIC in compliance with the Code and shall provide copies of such returns as required by the Code; (ii) make an election, on behalf of each REMIC created hereunder, to be treated as a REMIC on the federal tax return of such REMIC for its first taxable year, in accordance with the REMIC Provisions; and (iii) prepare and forward, or cause to be prepared and forwarded, to the Certificateholders and to any governmental taxing authority all information reports as and when required to be provided to them in accordance with the REMIC Provisions. The expenses of preparing and filing such returns shall be borne by the Trust Administrator. The Depositor, the Master Servicer and the related Servicer shall provide on a prompt and timely basis to the Trust Administrator or its designee such information with respect to each REMIC created hereunder as is in their possession and reasonably required or requested by the Trust Administrator to enable it to perform its obligations under this subsection.

In its capacity as attorney in fact and as agent on behalf of the tax matters person, the Trust Administrator shall also: (A) act on behalf of each REMIC created hereunder in relation to any tax matter or controversy involving the Trust Fund, (B) represent the Trust Fund in any administrative or judicial proceeding relating to an examination or audit by any governmental taxing authority with respect thereto and (C) cause to be paid solely from the sources provided herein the amount of any taxes imposed on each REMIC created hereunder when and as the same shall be due and payable (but such obligation shall not prevent the Trust Administrator or any other appropriate Person from contesting any such tax in appropriate proceedings and shall not prevent the Trust Administrator from withholding payment of such tax, if permitted by law, pending the outcome of such proceedings).

(e)

The Trust Administrator shall provide (i) to any transferor of a Class AR Certificate such information as is necessary for the application of any tax relating to the transfer of a Class AR Certificate to any Person who is not a permitted transferee, (ii) to the Certificateholders such information or reports as are required by the Code or the REMIC Provisions including reports relating to interest, original issue discount and market discount or premium and (iii) to the Internal Revenue Service the name, title, address and telephone number of the person who will serve as the representative of each REMIC created hereunder.

(f)

The Trustee, to the extent directed by the Trust Administrator, the Depositor and the Holder of the Class AR Certificates shall take any action or cause the Trust Fund to take any action necessary to create or maintain the status of each REMIC created hereunder as a REMIC under the REMIC Provisions and shall assist each other as necessary to create or maintain such status. Neither the Trustee, to the extent directed by the Trust Administrator, nor the Holder of the Class AR Certificates shall take any action, cause the Trust Fund to take any action or fail to take (or fail to cause the Trust Fund to take) any action that, under the REMIC Provisions, if taken or not taken, as the case may be, could (i) endanger the status of each REMIC created hereunder as a REMIC or (ii) result in the imposition of a tax upon a REMIC (including, but not limited to, the tax on prohibited transactions as defined in Code Section 860F(a)(2) and the tax on prohibited contributions set forth in Section 860G(d) of the Code) (either such event, an “Adverse REMIC Event”) unless the Trustee and the Trust Administrator have received an Opinion of Counsel (at the expense of the party seeking to take such action) to the effect that the contemplated action will not endanger such status or result in the imposition of such a tax.

The Trustee and the Trust Administrator shall not take or fail to take any action (whether or not authorized hereunder) as to which the Master Servicer, a Servicer or the Depositor has advised it in writing that it has received an Opinion of Counsel to the effect that an Adverse REMIC Event could occur with respect to such action. In addition, prior to taking any action with respect to a REMIC or their assets, or causing any REMIC created hereunder to take any action, which is not expressly permitted under the terms of this Agreement, the Trustee and the Trust Administrator will consult with the Master Servicer, the Servicers and the Depositor or their designees, in writing, with respect to whether such action could cause an Adverse REMIC Event to occur with respect to any REMIC created hereunder and the Trustee and the Trust Administrator shall not take any such action or cause that REMIC to take any such action as to which the Master Servicer, any Servicer or the Depositor has advised it in writing that an Adverse REMIC Event could occur.

In addition, prior to taking any action with respect to any REMIC created hereunder or the assets therein, or causing any REMIC created hereunder to take any action, which is not expressly permitted under the terms of this Agreement, the Holder of the Class AR Certificates will consult with the Trust Administrator or its designee, in writing, with respect to whether such action could cause an Adverse REMIC Event to occur with respect to any REMIC created hereunder, and no such Person shall take any action or cause the Trust Fund to take any such action as to which the Trustee or the Trust Administrator has advised it in writing that an Adverse REMIC Event could occur. The Trustee and the Trust Administrator may consult with counsel to make such written advice, and the cost of same shall be borne by the party seeking to take action not permitted by this Agreement.

At all times as may be required by the Code, the Trust Administrator will to the extent within its control and the scope of its duties more specifically set forth herein, maintain substantially all of the assets of each REMIC created hereunder as “qualified mortgages” as defined in Section 860G(a)(3) of the Code and “permitted investments” as defined in Section 860G(a)(5) of the Code.

(g)

In the event that any tax is imposed on “prohibited transactions” of any REMIC created hereunder, as defined in Section 860F(a)(2) of the Code, on “net income from foreclosure property” of such REMIC, as defined in Section 860G(c) of the Code, on any contributions to a REMIC after the Startup Day therefor pursuant to Section 860G(d) of the Code, or any other tax is imposed by the Code or any applicable provisions of state or local tax laws, such tax shall be charged (i) to the related Servicer, if such Servicer has in its sole discretion determined to indemnify the Trust Fund against such tax or if such tax arises out of or results from a breach of such Servicer’s duties under (x) Section 2.07(j) of this Agreement to not enter into any arrangement by which a REMIC would receive a fee or other compensation for services or to permit such REMIC to receive any income from assets other than “qualified mortgages” or “permitted investments”, (y) Section 3.01 of this Agreement to not make or permit any modification, waiver or amendment of any Mortgage Loan which would cause any REMIC created hereunder to fail to qualify as a REMIC or result in the imposition of any tax under Section 860F(a) or Section 860G(d) of the Code or (z) Section 3.11(c) of this Agreement to not cause any REO Property to fail to qualify as “foreclosure property” within the meaning of Section 860G(a)(8) of the Code or to subject any REMIC created hereunder to the imposition of any federal, state or local income taxes on the income earned from such Mortgaged Property under Section 860G(c) of the Code of otherwise, (ii) to the Master Servicer, if such tax arises out of or results from a breach by the Master Servicer of any of its obligations under this Agreement or if the Master Servicer has in its sole discretion determined to indemnify the Trust Fund against such tax, (iii) to the Trust Administrator, if such tax arises out of or results from a breach by the Trust Administrator of any of its obligations under this Article II, (iv) to the Trustee, if such tax arises out of or results from a breach by the Trustee of any of its obligations under this Article II, or (v) otherwise against amounts on deposit in the Collection Account as provided by Section 3.08 and on the Distribution Date(s) following such reimbursement the aggregate of such taxes shall be allocated in reduction of the Interest Distribution Amount on each Class entitled thereto in the same manner as if such taxes constituted a Prepayment Interest Shortfall.

In accordance with Section 2.07(c), the related Servicer, the Master Servicer, the Trust Administrator or the Trustee, as applicable, shall promptly deposit in the Certificate Account or Collection Account, as applicable, any amount of such tax.

For purposes of this Section 2.07(g), a tax is imposed following the final and unappealable determination under the Code of the amount of such tax and written notice thereof by the Tax Matters Person to the party to be charged.

The failure of the Master Servicer or the related Servicer to promptly deposit in the Certificate Account or Collection Account, as applicable, any amount of such tax shall be an Event of Default, as provided in Section 8.01(b). However, in the case of WMMSC, the prompt deposit of any such amount in the Certificate Account shall cure any Special Event of Default unless notice of such Special Event of Default is accompanied by an Opinion of Counsel, at the expense of WMMSC, to the effect that the cumulative effect of WMMSC’s breach or breaches, notwithstanding the deposit of the amounts of any such tax, shall have given rise to a substantial risk that any REMIC created hereunder would fail to continue to qualify as a REMIC.

(h)

The Trust Administrator shall, for federal income tax purposes, maintain books and records with respect to each REMIC created hereunder on a calendar year and on an accrual basis or as otherwise may be required by the REMIC Provisions.

(i)

Following the Startup Day, none of any Servicer, the Trustee or the Trust Administrator shall accept any contributions of assets to any REMIC created hereunder unless (subject to Section 2.05) such Servicer, the Trustee or the Trust Administrator shall have received an Opinion of Counsel (at the expense of the party seeking to make such contribution) to the effect that the inclusion of such assets in a REMIC will not cause that REMIC to fail to qualify as a REMIC at any time that any Certificates are outstanding, or subject that REMIC to any tax under the REMIC Provisions or other applicable provisions of federal, state and local law or ordinances.

(j)

None of any Servicer, the Trustee or the Trust Administrator shall (subject to Section 2.05) enter into any arrangement by which a REMIC will receive a fee or other compensation for services nor permit such REMIC to receive any income from assets other than “qualified mortgages” as defined in Section 860G(a)(3) of the Code or “permitted investments” as defined in Section 860G(a)(5) of the Code.

(k)

Within 30 days after the Closing Date, the Trust Administrator shall prepare and file with the Internal Revenue Service Form 8811, “Information Return for Real Estate Mortgage Investment Conduits (REMIC) and Issuers of Collateralized Debt Obligations” for each REMIC created hereunder.

(l)

None of the Trustee, the Trust Administrator, the Master Servicer or any Servicer shall sell, dispose of or substitute for any of the Mortgage Loans (except in connection with (i) the default, imminent default or foreclosure of a Mortgage Loan, including but not limited to, the acquisition or sale of a Mortgaged Property acquired by deed in lieu of foreclosure, (ii) the bankruptcy of any REMIC created hereunder, (iii) the termination of any REMIC created hereunder pursuant to Article X of this Agreement or (iv) a purchase of Mortgage Loans pursuant to Article II or III of this Agreement) nor acquire any assets for a REMIC, nor sell or dispose of any investments in the Collection Account or the Certificate Account for gain nor accept any contributions to a REMIC after the Closing Date (a) unless it has received an Opinion of Counsel that such sale, disposition, substitution or acquisition will not affect adversely the status of any REMIC created hereunder as a REMIC or (b) unless the Master Servicer or such Servicer has determined in its sole discretion to indemnify the Trust Fund against such tax.

(m)

In order to enable the Trustee and the Trust Administrator to perform their duties as set forth herein, the Depositor shall provide, or cause to be provided to the Trustee and the Trust Administrator, within ten days after the Closing Date, all information or data that the Trustee and the Trust Administrator determine to be relevant for tax purposes to the valuations and offering prices of the Certificates, including, without limitation, the price, yield, prepayment assumption and projected cash flows of the Certificates and the Mortgage Loans and the Trustee and the Trust Administrator shall be entitled to rely upon any and all such information and data in the performance of its duties set forth herein. Thereafter, the Master Servicer, or with respect to the WMMSC Serviced Mortgage Loans, WMMSC, shall provide, promptly upon request therefor, any such additional information or data (or with respect to WMMSC, any such additional loan level information and data regarding the WMMSC Serviced Mortgage Loans) that the Trustee or the Trust Administrator may from time to time reasonably request in order to enable the Trustee and the Trust Administrator to perform their duties as set forth herein and the Trustee and the Trust Administrator shall be entitled to rely upon any and all such information and data in the performance of its duties set forth herein. DLJMC shall indemnify the Trustee and the Trust Administrator and hold it harmless for any loss, liability, damage, claim or expense of the Trustee and the Trust Administrator arising from any failure of the Depositor to provide, or to cause to be provided, accurate information or data to the Trustee and the Trust Administrator on a timely basis. The Master Servicer shall indemnify the Trustee and the Trust Administrator and hold it harmless for any loss, liability, damage, claim or expense of the Trustee and the Trust Administrator arising from any failure of the Master Servicer to provide, or to cause to be provided, accurate information or data required to be provided by the Master Servicer to the Trustee and the Trust Administrator on a timely basis; provided, however, that if any Servicer (other than WMMSC and WMBFA) shall fail to provide such information to the Master Servicer upon timely request for such information by the Master Servicer, that Servicer shall indemnify the Master Servicer, the Trustee and the Trust Administrator and hold it harmless for any loss, liability, damage, claim or expense of the Master Servicer, the Trustee and the Trust Administrator arising from any failure of that Servicer to provide, or to cause to be provided, the information referred to above on a timely basis. WMMSC shall indemnify the Trustee and the Trust Administrator and hold each of them harmless for any loss, liability, damage, claim or expense, other than any special, indirect, punitive or consequential loss, liability, damage, claim or expense, of the Trustee and the Trust Administrator arising from any failure of WMMSC to provide, or to cause to be provided, the loan level information or data regarding the WMMSC Serviced Mortgage Loans reasonably requested by the Trustee or Trust Administrator, and required to be provided by WMMSC pursuant to this Section 2.07(m), on a timely basis. WMBFA shall indemnify the Master Servicer, the Trustee and the Trust Administrator and hold each of them harmless for any loss, liability, damage, claim or expense, other than any special, indirect, punitive or consequential loss, liability, damage, claim or expense, of the Master Servicer, the Trustee and the Trust Administrator arising from any failure of WMBFA to provide, or to cause to be provided, the loan level information or data regarding the WMBFA Serviced Mortgage Loans reasonably requested by the Master Servicer, and required to be provided by WMBFA pursuant to this Section 2.07(m), on a timely basis. The indemnification provisions hereunder shall survive the termination of this Agreement and shall extend to any co-trustee and co-trust administrator appointed pursuant to this Agreement.

(n)

The Trust Administrator shall treat the Basis Risk Reserve Fund as an outside reserve fund within the meaning of Treasury Regulation 1.860G 2(h) that is owned by the Class IV-X Certificateholders, as applicable, and that is not an asset of any REMIC created hereunder . The Trust Administrator shall account for the rights of the Class IV-A, Class IV-M-1 and Class IV M-2 Certificateholders to receive payments from the Basis Risk Reserve Fund as rights in an interest rate cap contract written by the Class IV-X Certificateholders in favor of the Class IV-A-1, Class IV-M-1 and Class IV M-2 Certificateholders and not as an obligation of the Master REMIC, whose obligation to pay such Certificates will be subject to a cap equal to the Net Funds Cap and shall account for such rights as property held separate and apart from the regular interests as required by Treasury regulation section 1.860G-2(i). Any amounts transferred to the Basis Risk Reserve Fund by the Master REMIC shall be treated as a distribution to the Class IV-X Certificates. In addition, the Class IV-X Certificateholders shall be deemed to have entered into a contractual arrangement with the Class AR Certificateholders whereby the Class AR Certificateholders agree to pay to the Class IV-X Certificateholders on each Distribution Date amounts that would, in the absence of such contractual agreement, be distributable with respect to the residual interest in the Master REMIC pursuant to Section 4.01(II)(d)(ix) (which amounts are expected to be zero). Thus each Class IV-A-1, Class IV-M-1 and Class IV M-2 Certificate shall be treated as representing ownership of not only Master REMIC regular interests, but also ownership of an interest in an interest rate cap contract. Each Class IV-X Certificate shall represent an obligation under an interest rate cap contract. For purposes of determining the issue price of Master REMIC regular interests, the Trust Administrator shall assume that the interest rate cap contract has a value of $5,000.

SECTION 2.08

Covenants of the Master Servicer and each Servicer.

The Master Servicer and each Servicer, severally and not jointly, hereby covenants to the Depositor, the Trustee and the Trust Administrator as follows:

(a)

Such Servicer or the Master Servicer shall comply in the performance of its obligations under this Agreement with all reasonable rules and requirements of the insurer under each Mortgage Guaranty Insurance Policy; and

(b)

No written information, certificate of an officer, statement furnished in writing or written report delivered to the Depositor, any affiliate of the Depositor, the Trustee or the Trust Administrator and prepared by the Master Servicer or such Servicer pursuant to this Agreement will contain any untrue statement of a material fact.

ARTICLE III

ADMINISTRATION AND SERVICING

OF MORTGAGE LOANS

SECTION 3.01

Master Servicer and Servicers to Service Mortgage Loans.

For and on behalf of the Certificateholders, as independent contractors of the Trustee, (i) the Master Servicer and each Servicer, severally and not jointly, shall service and administer the Non-Designated Mortgage Loans in accordance with the terms of this Agreement and with Accepted Servicing Practices and (ii) the Master Servicer shall service and administer each Designated Mortgage Loan according to the terms of the related Designated Servicing Agreement (except as otherwise provided in this Agreement). The obligations of each of Fairbanks, WMMSC and WMBFA hereunder to service and administer the Mortgage Loans shall be limited to the Fairbanks Serviced Mortgage Loans, the WMMSC Serviced Mortgage Loans and the WMBFA Serviced Mortgage Loans, respectively; and with respect to the duties and obligations of each Servicer, references herein to related “Mortgage Loans” shall be limited to the Fairbanks Serviced Mortgage Loans (and the related proceeds thereof and related REO Properties) in the case of Fairbanks, the WMMSC Serviced Mortgage Loans (and the related proceeds thereof and related REO Properties), in the case of WMMSC and the WMBFA Serviced Mortgage Loans (and the related proceeds thereof and related REO Properties), in the case of WMBFA; and in no event shall any Servicer have any responsibility or liability with respect to any of the other Mortgage Loans. The obligations of the Master Servicer to master service and administer the Mortgage Loans shall be limited to the Master Serviced Mortgage Loans, the Fairbanks Serviced Mortgage Loans, the Special Serviced Mortgage Loans and the WMBFA Serviced Mortgage Loans. Notwithstanding anything to the contrary contained in this Agreement, the Master Servicer shall have no obligations to master service or administer the WMMSC Serviced Mortgage Loans. In connection with such servicing and administration of the Non-Designated Mortgage Loans, the Master Servicer and each Servicer shall have full power and authority, acting alone and/or through Subservicers as provided in Section 3.02 hereof, to do or cause to be done any and all things that it may deem necessary or desirable in connection with such servicing and administration, including but not limited to, the power and authority, subject to the terms hereof (i) to execute and deliver, on behalf of the Certificateholders and the Trustee, customary consents or waivers and other instruments and documents, (ii) to consent to transfers of any Mortgaged Property and assumptions of the Mortgage Notes and related Mortgages (but only in the manner provided in this Agreement), (iii) to collect any Insurance Proceeds and other Liquidation Proceeds, and (iv) to effectuate foreclosure or other conversion of the ownership of the Mortgaged Property securing any Mortgage Loan; provided that neither the Master Servicer nor a Servicer shall take any action that is inconsistent with or prejudices the interests of the Trust Fund or the Certificateholders in any Mortgage Loan or the rights and interests of the Depositor, the Trustee, the Trust Administrator or the Certificateholders under this Agreement. The Master Servicer and each Servicer shall represent and protect the interests of the Trust Fund in the same manner as it protects its own interests in mortgage loans in its own portfolio in any claim, proceeding or litigation regarding a Non-Designated Mortgage Loan, and shall not make or permit any modification, waiver or amendment of any Non-Designated Mortgage Loan that would cause any REMIC created hereunder to fail to qualify as a REMIC or result in the imposition of any tax under Section 860F(a) or Section 860G(d) of the Code. Without limiting the generality of the foregoing, the Master Servicer and each Servicer, in its own name or in the name of the Depositor and the Trustee, is hereby authorized and empowered by the Depositor, the Trustee and the Trust Administrator, when the Master Servicer or such Servicer believes it appropriate in its reasonable judgment, to execute and deliver, on behalf of the Trustee, the Trust Administrator, the Depositor, the Certificateholders or any of them, any and all instruments of satisfaction or cancellation, or of partial or full release or discharge and all other comparable instruments, with respect to the Mortgage Loans, and with respect to the Mortgaged Properties held for the benefit of the Certificateholders. The Master Servicer and each Servicer shall prepare and deliver to the Depositor and/or the Trustee and/or the Trust Administrator such documents requiring execution and delivery by either or both of them as are necessary or appropriate to enable the Master Servicer or such Servicer to service and administer the Mortgage Loans to the extent that the Master Servicer or such Servicer is not permitted to execute and deliver such documents pursuant to the preceding sentence. Upon receipt of such documents, the Depositor and/or the Trustee or the Trust Administrator shall execute such documents and deliver them to the Master Servicer or such Servicer.

In accordance with the standards of the first paragraph of this Section 3.01 and unless determined in good faith to be a Nonrecoverable Advance, the Master Servicer and each Servicer shall advance or cause to be advanced funds as necessary for the purpose of effecting the payment of taxes and assessments on the Mortgaged Properties related to the Non-Designated Mortgage Loans, which advances constitute Servicing Advances and shall be reimbursable in the first instance from related collections from the Mortgagors pursuant to Section 3.06, and further as provided in Section 3.08. In no event will any Servicer be required to make any Servicing Advance which would constitute a Nonrecoverable Advance. The costs incurred by the Master Servicer or a Servicer, if any, in effecting the timely payments of taxes and assessments on the Mortgaged Properties related to the Mortgage Loans and related insurance premiums shall not, for the purpose of calculating monthly distributions to the Certificateholders, be added to the Stated Principal Balances of the related Mortgage Loans, notwithstanding that the terms of such Mortgage Loans so permit.

The Master Servicer and each Servicer hereby acknowledges that, to the extent the Master Servicer or such Servicer has previously serviced some or all of the Non-Designated Mortgage Loans pursuant to another servicing agreement, the provisions contained in this Agreement shall supersede the provisions contained in such other servicing agreement from and after the Closing Date. In addition, the Master Servicer hereby acknowledges that, to the extent the Master Servicer or the related Designated Servicer has previously serviced some or all of the related Designated Mortgage Loans pursuant to another servicing agreement, the provisions contained in the related Designated Servicing Agreement shall supersede the provisions contained in such other servicing agreement from and after the Closing Date.

Notwithstanding anything to the contrary in this Agreement, with respect to any action which according to the terms of this Agreement is to be performed by the Master Servicer and the applicable Servicer, (i) if such action relates to a Master Serviced Mortgage Loan, only the Master Servicer shall have an obligation to perform such action, (ii) if such action relates to a WMMSC Serviced Mortgage Loan, only WMMSC shall have an obligation to perform such action and (iii) if such action relates to a Mortgage Loan which is neither a Master Serviced Mortgage Loan nor a WMMSC Serviced Mortgage Loan, the related Servicer shall have an obligation to perform such action, and the Master Servicer shall also have an obligation to perform such action, but only if the related Servicer fails to do so.

Notwithstanding anything in this Agreement to the contrary, (i) the purchase of any WMMSC Serviced Mortgage Loan by any Person shall be subject to the rights of WMMSC to continue servicing such WMMSC Serviced Mortgage Loan for the same Servicing Fee substantially in accordance with the terms of this Agreement and (ii) the purchase of any WMBFA Serviced Mortgage Loan by any Person shall be subject to the rights of WMBFA to continue servicing such WMBFA Serviced Mortgage Loan for the same Servicing Fee substantially in accordance with the terms of this Agreement.

With respect to each Non-Designated Mortgage Loan (other than with respect to the WMMSC Serviced Mortgage Loans), the Master Servicer and the related Servicer, other than WMMSC, will fully furnish, in accordance with the Fair Credit Reporting Act and its implementing regulations, accurate and complete information (e.g., favorable and unfavorable) on its borrower credit files to Equifax, Experian and Trans Union Credit Information Company, on a monthly basis.

With respect to each WMMSC Serviced Mortgage Loan, WMMSC will furnish information regarding its borrower credit files to credit reporting agencies in compliance with the provisions of the Fair Credit Reporting Act and its implementing regulations applicable to WMMSC.

SECTION 3.02

Subservicing; Enforcement of the Obligations of Subservicers.

(a)

The Non-Designated Mortgage Loans may be subserviced by a Subservicer on behalf of the Master Servicer or the related Servicer in accordance with the servicing provisions of this Agreement, provided that the Subservicer is a FNMA-approved lender or a FHLMC seller/servicer in good standing. With respect to the Non-Designated Mortgage Loans, the Master Servicer and each Servicer may perform any of its servicing responsibilities hereunder or may cause the Subservicer to perform any such servicing responsibilities on its behalf, but the use by the Master Servicer or such Servicer of the Subservicer shall not release the Master Servicer or such Servicer from any of its obligations hereunder and the Master Servicer or such Servicer shall remain responsible hereunder for all acts and omissions of the Subservicer as fully as if such acts and omissions were those of such Master Servicer or Servicer. With respect to the Non-Designated Mortgage Loans, the Master Servicer and each Servicer shall pay all fees and expenses of any Subservicer engaged by the Master Servicer or such Servicer from its own funds.

Notwithstanding the foregoing with respect to the Non-Designated Mortgage Loans, the Master Servicer and each Servicer shall be entitled to outsource one or more separate servicing functions to a Person (each, an “Outsourcer”) that does not meet the eligibility requirements for a Subservicer, so long as such outsourcing does not constitute the delegation of the Master Servicer’s or such Servicer’s obligation to perform all or substantially all of the servicing of the related Non-Designated Mortgage Loans to such Outsourcer. In such event, the use by the Master Servicer or a Servicer of any such Outsourcer shall not release the Master Servicer or the related Servicer from any of its obligations hereunder and the Master Servicer or such Servicer shall remain responsible hereunder for all acts and omissions of such Outsourcer as fully as if such acts and omissions were those of the Master Servicer or such Servicer, and the Master Servicer or such Servicer shall pay all fees and expenses of the Outsourcer from such Master Servicer or Servicer’s own funds.

WMMSC may, in connection with its duties as Servicer hereunder, enter into transactions with any of its Affiliates relating to the WMMSC Serviced Mortgage Loans; provided that (a) WMMSC acts (i) in accordance with Accepted Servicing Practices and the terms of this Agreement, and (ii) in the ordinary course of business of WMMSC; and (b) the terms of such transaction are no less favorable to WMMSC than it would obtain in a comparable arm’s-length transaction with a Person that is not an Affiliate of WMMSC. Notwithstanding the preceding sentence, any such transaction between WMMSC and any of its Affiliates shall not release WMMSC from any of its obligations hereunder and WMMSC shall remain responsible hereunder for all acts and omissions of such Affiliate with respect to such Mortgage Loans serviced by it as fully as if such acts and omissions were those of the WMMSC. Any fees and expenses relating to such transaction between WMMSC and its Affiliate that are not otherwise reimbursable to WMMSC pursuant to this Agreement shall be borne by the parties thereto and shall not be an expense or fee of the Trust, the Depositor, the Trustee, the Trust Administrator, the Seller or the Master Servicer.

(b)

At the cost and expense of the Master Servicer or a Servicer, without any right of reimbursement from the Depositor, the Trustee, the Trust Administrator or the applicable Collection Account, the Master Servicer or such Servicer shall be entitled to terminate the rights and responsibilities of its Subservicer and arrange for any servicing responsibilities to be performed by a successor Subservicer meeting the requirements set forth in Section 3.02(a), provided, however, that nothing contained herein shall be deemed to prevent or prohibit the Master Servicer or such Servicer, at the Master Servicer’s or such Servicer’s option, from electing to service the related Mortgage Loans itself, provided further that WMBFA, in its capacity as Servicer of the WMBFA Serviced Mortgage Loans, shall not be deemed to be a Subservicer of the Master Servicer for purposes of the termination right set forth in this Section 3.02(b). In the event that the Master Servicer or a Servicer’s responsibilities and duties under this Agreement are terminated pursuant to Section 8.01, and if requested to do so by the Trustee or Trust Administrator, the Master Servicer or such Servicer shall, at its own cost and expense terminate the rights and responsibilities of its Subservicer as soon as is reasonably possible. The Master Servicer and each Servicer shall pay all fees, expenses or penalties necessary in order to terminate the rights and responsibilities of its Subservicer from such Master Servicer or Servicer’s own funds without any right of reimbursement from the Depositor, Trustee, Trust Administrator, or the applicable Collection Account.

(c)

Notwithstanding any of the provisions of this Agreement relating to agreements or arrangements between the Master Servicer or a Servicer and its Subservicer, the Master Servicer or a Servicer and its Outsourcer, or any reference herein to actions taken through the Subservicer, the Outsourcer, or otherwise, neither the Master Servicer nor the related Servicer shall be relieved of its obligations to the Depositor, Trustee, the Trust Administrator or Certificateholders and shall be obligated to the same extent and under the same terms and conditions as if it alone were servicing and administering the related Mortgage Loans. The Master Servicer and each Servicer shall be entitled to enter into an agreement with its Subservicer and Outsourcer for indemnification of the Master Servicer or such Servicer or Outsourcer, as applicable, by such Subservicer and nothing contained in this Agreement shall be deemed to limit or modify such indemnification.

For purposes of this Agreement, the Master Servicer or a Servicer shall be deemed to have received any collections, recoveries or payments with respect to the related Non-Designated Mortgage Loans that are received by a related Subservicer regardless of whether such payments are remitted by the Subservicer to the Master Servicer or such Servicer.

Any Subservicing Agreement and any other transactions or services relating to the Non-Designated Mortgage Loans involving a Subservicer shall be deemed to be between the Subservicer, and the Master Servicer or the related Servicer alone, and the Depositor, the Trustee, the Trust Administrator and the other Servicers and the Special Servicer shall have no obligations, duties or liabilities with respect to a Subservicer including no obligation, duty or liability of the Depositor, Trustee, the Trust Administrator, the Special Servicer or other Servicers to pay a Subservicer’s fees and expenses.

(d)

Fairbanks is hereby authorized to enter into a financing or other facility (any such arrangement, a “Facility”) under which (i) Fairbanks assigns or pledges to another person (a “Lender”) (A) Xxxxxxxx’x rights under this Agreement to be reimbursed for any Advances or Servicing Advances, and (B) any and all rights of Fairbanks under this Agreement resulting from Xxxxxxxx’x performance of its obligations under this Agreement, including, without limitation, any Servicing Fees, Special Servicing Fees, interest income, Ancillary Income, and other payments received by Fairbanks for servicing the Fairbanks Serviced Mortgage Loans or Special Serviced Mortgage Loans and (ii) the Lender agrees to fund some or all Advances and/or Servicing Advances required to be made by Fairbanks pursuant to this Agreement. No consent of the Trustee, Trust Administrator, Certificateholders or any other party is required before Fairbanks may enter into a Facility; provided, however, that the consent of each of the Trustee and Trust Administrator shall be required before Fairbanks may cause to be outstanding at one time more than one Facility. Notwithstanding the existence of any Facility, Fairbanks shall remain obligated pursuant to this Agreement to make Advances and Servicing Advances pursuant to and as required by this Agreement, and to perform all duties and obligations of Fairbanks under this Agreement and shall not be relieved of such obligations by virtue of such Facility.

SECTION 3.03

Notification of Adjustments.

With respect to each Mortgage Loan, the Master Servicer or the related Servicer shall adjust the Mortgage Rate on the related Adjustment Date in compliance with the requirements of applicable law and the related Mortgage and Mortgage Note. The Master Servicer or the related Servicer shall execute and deliver any and all necessary notices required under applicable law and the terms of the related Mortgage Note and Mortgage regarding the Mortgage Rate adjustments. Upon the discovery by the Master Servicer or the related Servicer or the receipt of notice from the Trust Administrator that the Master Servicer or such Servicer has failed to adjust a Mortgage Rate in accordance with the terms of the related Mortgage Note, the Master Servicer or such Servicer shall immediately deposit in the Certificate Account from its own funds the amount of any interest loss or deferral caused the Trust Administrator thereby.

SECTION 3.04

Trust Administrator to Act as Master Servicer or Servicer.

In the event that (A) the Master Servicer shall for any reason no longer be Master Servicer hereunder or (B) any Servicer shall for any reason no longer be a Servicer hereunder and, with respect to any Servicer other than WMMSC, the Master Servicer shall for any reason no longer be Master Servicer hereunder (including, in each case, by reason of an Event of Default), the Trust Administrator or its successor shall thereupon assume all of the rights and obligations of the Master Servicer or such Servicer hereunder arising thereafter (except that the Trust Administrator shall not be (i) liable for losses of the Master Servicer or such Servicer pursuant to Section 3.09 hereof or any acts or omissions of the related predecessor of the Master Servicer or such Servicer hereunder, (ii) obligated to make Advances if it is prohibited from doing so by applicable law, (iii) obligated to effectuate repurchases or substitutions of Mortgage Loans hereunder including, but not limited to, repurchases or substitutions of Mortgage Loans pursuant to Section 2.02 or 2.03 hereof or (iv) deemed to have made any representations and warranties of the Master Servicer or such Servicer hereunder). Any such assumption shall be subject to Section 8.02 hereof.

The Master Servicer and each Servicer shall, upon request of the Trust Administrator, but at the expense of the Master Servicer or such Servicer, deliver to the assuming party all documents and records relating to each Subservicing Agreement or substitute Subservicing Agreement and the Mortgage Loans then being serviced thereunder and hereunder by the Master Servicer or such Servicer and an accounting of amounts collected or held by it and otherwise use its best efforts to effect the orderly and efficient transfer of the Subservicing Agreement or substitute Subservicing Agreement to the assuming party.

SECTION 3.05

Collection of Mortgage Loans; Collection Accounts; Certificate Account.

(a)

Continuously from the date hereof until the principal and interest on all Mortgage Loans have been paid in full or such Non-Designated Mortgage Loans have become Liquidated Mortgage Loans, the Master Servicer and each Servicer shall proceed in accordance with Accepted Servicing Practices to collect all payments due under each of the related Non-Designated Mortgage Loans when the same shall become due and payable to the extent consistent with this Agreement and the terms and provisions of any related Mortgage Guaranty Insurance Policy and shall take special care with respect to Non-Designated Mortgage Loans for which the Master Servicer or a Servicer collects escrow payments in ascertaining and estimating Escrow Payments and all other charges that will become due and payable with respect to the Mortgage Loans and the related Mortgaged Properties, to the end that the installments payable by the related Mortgagors will be sufficient to pay such charges as and when they become due and payable. Consistent with the foregoing, in connection with Non-Designated Mortgage Loans which it is directly servicing, the Master Servicer or each Servicer may in its discretion (i) waive any late payment charge or any prepayment charge or penalty interest in connection with the prepayment of a Non-Designated Mortgage Loan and (ii) extend the Due Dates for payments due on a Mortgage Note for a period not greater than 180 days; provided, however, that neither the Master Servicer nor such Servicer can extend the maturity of any such Non-Designated Mortgage Loan past the date on which the final payment is due on the latest maturing Mortgage Loan as of the Cut-off Date. In the event of any such arrangement, the Master Servicer, other than with respect to the WMMSC Serviced Mortgage Loans, or the related Servicer shall make Advances on the related Non-Designated Mortgage Loan in accordance with the provisions of Section 5.01 during the scheduled period in accordance with the amortization schedule of such Mortgage Loan without modification thereof by reason of such arrangements. Neither the Master Servicer nor any Servicer shall be required to institute or join in litigation with respect to collection of any payment (whether under a Mortgage, Mortgage Note or otherwise or against any public or governmental authority with respect to a taking or condemnation) if it reasonably believes that enforcing the provision of the Mortgage or other instrument pursuant to which such payment is required is prohibited by applicable law.

With respect to any Designated Mortgage Loan, the Master Servicer, pursuant to its rights under the related Designated Servicing Agreement, shall not consent to any extension of the maturity of such Designated Mortgage Loan past the date on which the final payment is due on the latest maturing Mortgage Loan as of the Cut-off Date.

(b)

The Master Servicer and each Servicer shall segregate and hold all funds collected and received pursuant to a Non-Designated Mortgage Loan separate and apart from any of its own funds and general assets and shall establish and maintain one or more Collection Accounts, in the form of time deposit or demand accounts, titled “[[Master] Servicer’s name], in trust for the Holders of Credit Suisse First Boston Mortgage Securities Corp., Mortgage-Backed Pass-Through Certificates, Series 2003-AR15” or, if established and maintained by a Subservicer on behalf of the Master Servicer or a Servicer, “[Subservicer’s name], in trust for [[Master]Servicer’s name]” or “[Subservicer’s name], as agent, trustee and/or bailee of principal and interest custodial account for [[Master] Servicer’s name], its successors and assigns, for various owners of interest in [Servicer’s name] mortgage-backed pools. In the event that a Subservicer employs a subservicer, the Collection Account shall be titled “[name of Subservicer’s subservicer], in trust for [Subservicer’s name].” Each Collection Account shall be an Eligible Account acceptable to the Depositor, the Trust Administrator and Trustee. Funds deposited in a Collection Account may be drawn on by the Master Servicer or the related Servicer in accordance with Section 3.08. Any funds deposited in a Collection Account (other than an account established by WMMSC) shall either be invested in Eligible Investments or at all times be fully insured to the full extent permitted under applicable law. Notwithstanding the foregoing, one of the Collection Accounts established by WMMSC shall be an Investment Account.

(c)

The Master Servicer and each Servicer shall deposit in the applicable Collection Account on a daily basis, unless otherwise indicated, and retain therein, the following collections remitted by Subservicers or payments received by the Master Servicer or such Servicer and payments made by the Master Servicer or such Servicer subsequent to the Cut-off Date, other than payments of principal and interest due on or before the Cut-off Date:

(v) all Advances made by the Master Servicer or such Servicer pursuant to Section 5.01;

(vi) no later than the withdrawal from the Collection Account pursuant to Section 3.08(a)(viii) each month, the applicable amount of the Compensating Interest Payment for the Master Servicer or such Servicer (or if such Servicer, other than WMMSC, defaults in such obligation, the Master Servicer) for the related Prepayment Period. The aggregate of such deposits shall be made from the Master Servicer’s or such Servicer’s own funds, without reimbursement therefore;

(vii) any amounts required to be deposited by the Master Servicer or such Servicer in respect of net monthly income from REO Property related to any Non-Designated Mortgage Loan pursuant to Section 3.11;

(viii) any other amounts required to be deposited hereunder; and

Such direction may be accomplished by delivering an Officer’s Certificate to the Trust Administrator which describes the amounts deposited in error in the Certificate Account. All funds deposited in the Certificate Account shall be held by the Trust Administrator in trust for the Certificate holders until disbursed in accordance with this Agreement or withdrawn in accordance with Section 3.08(b). In no event shall the Trust Administrator incur liability for withdrawals from the Certificate Account at the direction of the Master Servicer or WMMSC.

SECTION 3.09

Maintenance of Hazard Insurance; Mortgage Impairment Insurance and Mortgage Guaranty Insurance Policy; Claims; Restoration of Mortgaged Property.

(a)

The Master Servicer and each Servicer shall cause to be maintained for each Non-Designated Mortgage Loan hazard insurance such that all buildings upon the related Mortgaged Property are insured by a generally acceptable insurer rated either: “V” or better in the current Best’s Key Rating Guide (“Best’s”) or acceptable to FNMA or FHLMC against loss by fire, hazards of extended coverage and such other hazards as are customary in the area where the Mortgaged Property is located, in an amount which is at least equal to the lesser of (i) the replacement value of the improvements securing such Non-Designated Mortgage Loan and (ii) the greater of (A) the outstanding principal balance of such Non-Designated Mortgage Loan and (B) an amount such that the proceeds of such policy shall be sufficient to prevent the Mortgagor and/or the mortgagee from becoming a co insurer.

If upon origination of the Non-Designated Mortgage Loan, the related Mortgaged Property was located in an area identified in the Federal Register by the Federal Emergency Management Agency as having special flood hazards (and such flood insurance has been made available), the Master Servicer or the related Servicer shall cause a flood insurance policy to be maintained with respect to such Non-Designated Mortgage Loan. Such policy shall meet the requirements of the current guidelines of the Federal Insurance Administration and be in an amount representing coverage equal to the lesser of (i) the minimum amount required, under the terms of coverage, to compensate for any damage or loss on a replacement cost basis (or the unpaid principal balance of the mortgage if replacement cost coverage is not available for the type of building insured) and (ii) the maximum amount of insurance which is available under the Flood Disaster Protection Act of 1973, as amended.

If a Mortgage related to a Non-Designated Mortgage Loan is secured by a unit in a condominium project, the Master Servicer or the related Servicer shall verify that the coverage required of the owner’s association, including hazard, flood, liability, and fidelity coverage, is being maintained in accordance with the requirements of the Master Servicer or the related Servicer for mortgage loans that it services on its own account.

The Master Servicer and each Servicer shall cause to be maintained on each Mortgaged Property related to a Non-Designated Mortgage Loan such other additional special hazard insurance as may be required pursuant to such applicable laws and regulations as shall at any time be in force and as shall require such additional insurance, or pursuant to the requirements of any Mortgage Guaranty Insurance Policy insurer, or as may be required to conform with Accepted Servicing Practices to the extent permitted by the Mortgage Note, the Mortgage or applicable law provided that the Master Servicer or the related Servicer shall not be required to bear the cost of such insurance.

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

Neither the Master Servicer nor any Servicer shall interfere with the Mortgagor’s freedom of choice at the origination of such Non-Designated Mortgage Loan in selecting either his insurance carrier or agent, provided, however, that the Master Servicer or such Servicer shall not accept any such insurance policies from insurance companies unless such companies are rated: B:III or better in Best’s or acceptable to FNMA or FHLMC and are licensed to do business in the jurisdiction in which the Mortgaged Property is located. The Master Servicer or the related Servicer shall determine that such policies provide sufficient risk coverage and amounts, that they insure the property owner, and that they properly describe the property address.

Pursuant to Section 3.05, any amounts collected by the Master Servicer or a Servicer under any such policies (other than amounts to be deposited in the related Escrow Account and applied to the restoration or repair of the related Mortgaged Property, or property acquired in liquidation of the Non-Designated Mortgage Loan, or to be released to the Mortgagor, in accordance with such Servicer’s normal servicing procedures) shall be deposited in the related Collection Account (subject to withdrawal pursuant to Section 3.08(a)).

Any cost incurred by the Master Servicer or a Servicer in maintaining any such insurance shall not, for the purpose of calculating monthly distributions to the Certificateholders or remittances to the Trust Administrator for their benefit, be added to the principal balance of the Non-Designated Mortgage Loan, notwithstanding that the terms of the Non-Designated Mortgage Loan so permit. Such costs shall constitute a Servicing Advance and will be reimbursable to the Master Servicer or the related Servicer to the extent permitted by Section 3.08 hereof. It is understood and agreed that no earthquake or other additional insurance is to be required of any Mortgagor related to a Non-Designated Mortgage Loan or maintained on property acquired in respect of a Mortgage other than pursuant to such applicable laws and regulations as shall at any time be in force and as shall require such additional insurance.

(b)

In the event that the Master Servicer or a Servicer shall obtain and maintain a blanket policy insuring against losses arising from fire and hazards covered under extended coverage on all of the related Non-Designated Mortgage Loans, then, to the extent such policy provides coverage in an amount equal to the amount required pursuant to Section 3.09(a) and otherwise complies with all other requirements of Section 3.09(a), it shall conclusively be deemed to have satisfied its obligations as set forth in Section 3.09(a). Any amounts collected by the Master Servicer or a Servicer under any such policy relating to a Non-Designated Mortgage Loan shall be deposited in the related Collection Account subject to withdrawal pursuant to Section 3.08(a). Such policy may contain a deductible clause, in which case, in the event that there shall not have been maintained on the related Mortgaged Property a policy complying with Section 3.09(a), and there shall have been a loss which would have been covered by such policy, the Master Servicer or the related Servicer shall deposit in the related Collection Account at the time of such loss the amount not otherwise payable under the blanket policy because of such deductible clause, such amount to be deposited from such Servicer’s funds, without reimbursement therefor. Upon request of the Trust Administrator, the Master Servicer or a Servicer shall cause to be delivered to the Trust Administrator a certified true copy of such policy and a statement from the insurer thereunder that such policy shall in no event be terminated or materially modified without 30 days’ prior written notice to the Trust Administrator. In connection with its activities as Servicer of the related Non-Designated Mortgage Loans, the Master Servicer or such Servicer agrees to present, on behalf of itself, the Depositor, and the Trust Administrator for the benefit of the Certificateholders, claims under any such blanket policy.

(c)

With respect to each Non-Designated Mortgage Loan with a Loan-to-Value Ratio in excess of 80% which the related Seller represented to be covered by a Mortgage Guaranty Insurance Policy as of the Cut-off Date, the Master Servicer or the related Servicer shall, without any cost to the Depositor or Trust Administrator, maintain or cause the Mortgagor to maintain in full force and effect a Mortgage Guaranty Insurance Policy insuring that portion of the Non-Designated Mortgage Loan in excess of 75% of value, and shall pay or shall cause the Mortgagor to pay, the premium thereon on a timely basis, until the loan-to-value ratio of such Non-Designated Mortgage Loan is reduced to 80%, based on either (i) a current appraisal of the Mortgaged Property or (ii) the appraisal of the Mortgaged Property obtained at the time the Non-Designated Mortgage Loan was originated. In the event that such Mortgage Guaranty Insurance Policy shall be terminated prior to the loan-to-value ratio of such Mortgage Loan being reduced to 80%, the Master Servicer or the related Servicer shall obtain from another Qualified Insurer a comparable replacement policy, with a total coverage equal to the remaining coverage of such terminated Mortgage Guaranty Insurance Policy. If the insurer shall cease to be a Qualified Insurer, the Master Servicer or the related Servicer shall determine whether recoveries under the Mortgage Guaranty Insurance Policy are jeopardized for reasons related to the financial condition of such insurer, it being understood that the Master Servicer or such Servicer shall in no event have any responsibility or liability for any failure to recover under the Mortgage Guaranty Insurance Policy for such reason. If the Master Servicer or the related Servicer determines that recoveries are so jeopardized, it shall notify the Mortgagor, if required, and obtain from another Qualified Insurer a replacement insurance policy. The Master Servicer or the related Servicer shall not take any action which would result in noncoverage under any applicable Mortgage Guaranty Insurance Policy of any loss which, but for the actions of the Master Servicer or such Servicer would have been covered thereunder. In connection with any assumption or substitution agreement entered into or to be entered into pursuant to Section 3.10, the Master Servicer and each Servicer shall promptly notify the insurer under the related Mortgage Guaranty Insurance Policy, if any, of such assumption or substitution of liability in accordance with the terms of such Mortgage Guaranty Insurance Policy and shall take all actions which may be required by such insurer as a condition to the continuation of coverage under such Mortgage Guaranty Insurance Policy provided that such required actions are in compliance with all applicable law. If such Mortgage Guaranty Insurance Policy is terminated as a result of such assumption or substitution of liability, the Master Servicer or the related Servicer shall obtain a replacement Mortgage Guaranty Insurance Policy as provided above; provided that under applicable law and the terms of the related Mortgage Note and Mortgage the cost of such policy may be charged to the successor Mortgagor.

With respect to each Non-Designated Mortgage Loan covered by a Lender Paid Mortgage Guaranty Insurance Policy, the applicable Servicer agrees to effect timely payment of the premiums on such Mortgage Guaranty Insurance Policy from amounts on deposit in the Collection Account, or deducted by such Servicer prior to deposit into the applicable Collection Account or pursuant to Section 3.05(c) with respect to such Non-Designated Mortgage Loan. If amounts on deposit in the Collection Account, or deducted by such Servicer prior to deposit into the applicable Collection Account pursuant to Section 3.05(c) with respect to such Non-Designated Mortgage Loan, are not sufficient to pay the premiums on such Mortgage Guaranty Insurance Policy, the applicable Servicer agrees to effect timely payment of such premiums, and such costs shall be recoverable by such Servicer from the related Liquidation Proceeds or otherwise as a Servicing Advance pursuant to Section 3.08(a). With respect to each Non-Designated Mortgage Loan covered by a Mortgage Guaranty Insurance Policy that is not Lender Paid, the Servicer agrees to effect timely payment of the premiums on such Mortgage Guaranty Insurance Policy, and such costs not otherwise recoverable from the Mortgagor shall be recoverable by such Servicer from the related Liquidation Proceeds or otherwise as a Servicing Advance pursuant to Section 3.08(a).

(d)

In connection with its activities as servicer, the Master Servicer and each Servicer agrees to prepare and present, on behalf of itself, the Depositor, the Trustee, the Trust Administrator and the Certificateholders, claims to the insurer under any Mortgage Guaranty Insurance Policy related to a Non-Designated Mortgage Loan in a timely fashion in accordance with the terms of such Mortgage Guaranty Insurance Policy and, in this regard, to take such reasonable action as shall be necessary to permit recovery under any Mortgage Guaranty Insurance Policy respecting defaulted Non-Designated Mortgage Loans. Pursuant to Section 3.05, any amounts collected by the Master Servicer or a Servicer under any Mortgage Guaranty Insurance Policy shall be deposited in the related Collection Account, subject to withdrawal pursuant to Section 3.08.

(e)

With respect to a Non-Designated Mortgage Loan, neither the Master Servicer nor a Servicer need obtain the approval of the Trustee or the Trust Administrator prior to releasing any Insurance Proceeds to the Mortgagor to be applied to the restoration or repair of the Mortgaged Property if such release is in accordance with Accepted Servicing Practices. At a minimum, the Master Servicer and each Servicer shall comply with the following conditions in connection with any such release of Insurance Proceeds:

(i) the Master Servicer or such Servicer shall receive satisfactory independent verification of completion of repairs and issuance of any required approvals with respect thereto;

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

(iii) pending repairs or restoration, the Master Servicer or such Servicer shall place the Insurance Proceeds in the related Escrow Account.

(f)

With respect to a Non-Designated Mortgage Loan, if the Trust Administrator is named as an additional loss payee, the Master Servicer or the related Servicer is hereby empowered to endorse any loss draft issued in respect of such a claim in the name of the Trustee or the Trust Administrator.

SECTION 3.10

Enforcement of Due on Sale Clauses; Assumption Agreements.

(a)

With respect to a Non-Designated Mortgage Loan, the Master Servicer and each Servicer shall use its best efforts to enforce any “due-on-sale” provision contained in any related Mortgage or Mortgage Note and to deny assumption by the person to whom the Mortgaged Property has been or is about to be sold whether by absolute conveyance or by contract of sale, and whether or not the Mortgagor remains liable on the Mortgage and the Mortgage Note. When the Mortgaged Property has been conveyed by the Mortgagor, the Master Servicer or the related Servicer shall, to the extent it has knowledge of such conveyance, exercise its rights to accelerate the maturity of such Non-Designated Mortgage Loan under the “due-on-sale” clause applicable thereto, provided, however, that the Master Servicer or such Servicer shall not exercise such rights if prohibited by law from doing so or if the exercise of such rights would impair or threaten to impair any recovery under the related Mortgage Guaranty Insurance Policy, if any.

(b)

With respect to a Non-Designated Mortgage Loan, if the Master Servicer or a Servicer reasonably believes it is unable under applicable law to enforce such “due-on-sale” clause, the Master Servicer or such Servicer shall enter into (i) an assumption and modification agreement with the person to whom such property has been conveyed, pursuant to which such person becomes liable under the Mortgage Note and the original Mortgagor remains liable thereon or (ii) in the event the Master Servicer or such Servicer is unable under applicable law to require that the original Mortgagor remain liable under the Mortgage Note, a substitution of liability agreement with the purchaser of the Mortgaged Property pursuant to which the original Mortgagor is released from liability and the purchaser of the Mortgaged Property is substituted as Mortgagor and becomes liable under the Mortgage Note. Notwithstanding the foregoing, the Master Servicer or a Servicer shall not be deemed to be in default under this Section by reason of any transfer or assumption which the Master Servicer or such Servicer reasonably believes it is restricted by law from preventing, for any reason whatsoever. In connection with any such assumption, no material term of the Mortgage Note, including without limitation, the Mortgage Rate borne by the related Mortgage Note, the term of the Non-Designated Mortgage Loan or the outstanding principal amount of the Non-Designated Mortgage Loan shall be changed.

(c)

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

(d)

With respect to a Non-Designated Mortgage Loan, subject to the Master Servicer’s and each Servicer’s duty to enforce any due-on-sale clause to the extent set forth in this Section 3.10, in any case in which the related Mortgaged Property has been conveyed to a Person by the related Mortgagor, and such Person is to enter into an assumption agreement or modification agreement or supplement to the Mortgage Note or Mortgage that requires the signature of the Trustee, or if an instrument of release signed by the Trustee is required releasing the Mortgagor from liability on the Non-Designated Mortgage Loan, the Master Servicer or such Servicer shall prepare and deliver or cause to be prepared and delivered to the Trustee for signature and shall direct, in writing, the Trustee to execute the assumption agreement with the Person to whom the Mortgaged Property is to be conveyed and such modification agreement or supplement to the Mortgage Note or Mortgage or other instruments as are reasonable or necessary to carry out the terms of the Mortgage Note or Mortgage or otherwise to comply with any applicable laws regarding assumptions or the transfer of the Mortgaged Property to such Person. In connection with any such assumption, no material term of the Mortgage Note may be changed. Together with each such substitution, assumption or other agreement or instrument delivered to the Trustee for execution by it, the Master Servicer or the related Servicer shall deliver an Officer’s Certificate signed by a Servicing Officer stating that the requirements of this subsection have been met in connection therewith. The Master Servicer or the related Servicer shall notify the Trustee that any such substitution or assumption agreement has been completed by forwarding to the Trustee the original of such substitution or assumption agreement, which in the case of the original shall be added to the related Mortgage File and shall, for all purposes, be considered a part of such Mortgage File to the same extent as all other documents and instruments constituting a part thereof. Any fee collected by the Master Servicer or a Servicer for entering into an assumption or substitution of liability agreement will be retained by the Master Servicer or such Servicer as additional servicing compensation.

SECTION 3.11

Realization Upon Defaulted Mortgage Loans; Repurchase of Certain Mortgage Loans.

(a)

The Master Servicer and each Servicer shall use reasonable efforts to foreclose upon or otherwise comparably convert the ownership of properties securing such of the related Non-Designated Mortgage Loans as come into and continue in default and as to which no satisfactory arrangements can be made for collection of delinquent payments. In connection with such foreclosure or other conversion, the Master Servicer and each Servicer shall take such action as (i) the Master Servicer or such Servicer would take under similar circumstances with respect to a similar mortgage loan held for its own account for investment, (ii) shall be consistent with Accepted Servicing Practices, (iii) the Master Servicer or such Servicer shall determine consistently with Accepted Servicing Practices to be in the best interest of the Trustee and Certificateholders, and (iv) is consistent with the requirements of the insurer under any Required Insurance Policy; provided, however, that the Master Servicer or such Servicer shall not be required to expend its own funds in connection with any foreclosure or towards the restoration of any property unless it shall determine (i) that such restoration and/or foreclosure will increase the proceeds of liquidation of the related Non-Designated Mortgage Loan after reimbursement to itself of such expenses and (ii) that such expenses will be recoverable to it through Liquidation Proceeds. Any funds expended by the Master Servicer or any Servicer pursuant to this Section 3.11(a) shall be reimbursable in full pursuant to Section 3.08(a)(iii). The Master Servicer or the related Servicer shall be responsible for all other costs and expenses incurred by it in any such proceedings; provided, however, that it shall be entitled to reimbursement thereof from the Liquidation Proceeds with respect to the related Mortgaged Property or otherwise as a Servicing Advance in accordance with Section 3.08(a).

With respect to any Non-Designated Mortgage Loans, notwithstanding anything to the contrary contained in this Agreement, in connection with a foreclosure or acceptance of a deed in lieu of foreclosure, in the event the Master Servicer or the related Servicer has reasonable cause to believe that the related Mortgaged Property is contaminated by hazardous or toxic substances or wastes, or if the Trust Administrator otherwise requests, an environmental inspection or review of such Mortgaged Property conducted by a qualified inspector shall be arranged for by the Master Servicer or such Servicer. Upon completion of the inspection, the Master Servicer or the related Servicer shall promptly provide the Trust Administrator with a written report of environmental inspection.

In the event the environmental inspection report indicates that the Mortgaged Property is contaminated by hazardous or toxic substances or wastes, the Master Servicer or the related Servicer shall not proceed with foreclosure or acceptance of a deed in lieu of foreclosure if the estimated costs of the environmental clean up, as estimated in the environmental inspection report, together with the Servicing Advances and Advances made by the Master Servicer or such Servicer and the estimated costs of foreclosure or acceptance of a deed in lieu of foreclosure exceeds the estimated value of the Mortgaged Property. If however, the aggregate of such clean up and foreclosure costs, Advances and Servicing Advances are less than or equal to the estimated value of the Mortgaged Property, then the Master Servicer or the related Servicer may, in its reasonable judgment and in accordance with Accepted Servicing Practices, choose to proceed with foreclosure or acceptance of a deed in lieu of foreclosure and the Master Servicer or such Servicer shall be reimbursed for all reasonable costs associated with such foreclosure or acceptance of a deed in lieu of foreclosure and any related environmental clean up costs, as applicable, from the related Liquidation Proceeds, or if the Liquidation Proceeds are insufficient to reimburse fully the Master Servicer or such Servicer, the Master Servicer or such Servicer shall be entitled to be reimbursed from amounts in the related Collection Account pursuant to Section 3.08(a) hereof. In the event the Master Servicer or the related Servicer does not proceed with foreclosure or acceptance of a deed in lieu of foreclosure pursuant to the first sentence of this paragraph, the Master Servicer or such Servicer shall be reimbursed for all Advances and Servicing Advances made with respect to the related Mortgaged Property from the related Collection Account pursuant to Section 3.08(a) hereof, and the Master Servicer or such Servicer shall have no further obligation to service such Non-Designated Mortgage Loan under the provisions of this Agreement.

(b)

With respect to any REO Property related to a Non-Designated Mortgage Loan, subject to applicable law, the deed or certificate of sale shall be taken in the name of the Trustee for the benefit of the Certificateholders, or its nominee, on behalf of the Certificateholders. The Trustee’s name shall be placed on the title to such REO Property solely as the Trustee hereunder and not in its individual capacity. The Master Servicer or the related Servicer shall ensure that the title to such REO Property references this Agreement and the Trustee capacity hereunder. Pursuant to its efforts to sell such REO Property, the Master Servicer or the related Servicer shall in accordance with Accepted Servicing Practices manage, conserve, protect and operate each REO Property for the purpose of its prompt disposition and sale. The Master Servicer or the related Servicer, either itself or through an agent selected by the Master Servicer or such Servicer, shall manage, conserve, protect and operate the REO Property in the same manner that it manages, conserves, protects and operates other foreclosed property for its own account, and in the same manner that similar property in the same locality as the REO Property is managed. Upon request, the Master Servicer or the related Servicer shall furnish to the Trust Administrator on or before each Distribution Date a statement with respect to any REO Property covering the operation of such REO Property for the previous calendar month and the Master Servicer’s or such Servicer’s efforts in connection with the sale of such REO Property and any rental of such REO Property incidental to the sale thereof for the previous calendar month. That statement shall be accompanied by such other information as the Trust Administrator shall reasonably request and which is necessary to enable the Trust Administrator to comply with the reporting requirements of the REMIC Provisions. The net monthly rental income, if any, from such REO Property shall be deposited in the related Collection Account no later than the close of business on each Determination Date. The Master Servicer or the related Servicer shall perform the tax reporting and withholding required by Sections 1445 and 6050J of the Code with respect to foreclosures and abandonments, the tax reporting required by Section 6050H of the Code with respect to the receipt of mortgage interest from individuals and any tax reporting required by Section 6050P of the Code with respect to the cancellation of indebtedness by certain financial entities, by preparing such tax and information returns as may be required, in the form required, and delivering the same to the Trust Administrator for filing.

To the extent consistent with Accepted Servicing Practices, the Master Servicer or the related Servicer shall also maintain on each REO Property related to a Non-Designated Mortgage Loan fire and hazard insurance with extended coverage in an amount which is equal to the outstanding principal balance of the related Non-Designated Mortgage Loan (as reduced by any amount applied as a reduction of principal at the time of acquisition of the REO Property), liability insurance and, to the extent required and available under the Flood Disaster Protection Act of 1973, as amended, flood insurance in the amount required above.

(c)

In the event that the Trust Fund acquires any Mortgaged Property as aforesaid or otherwise in connection with a default or imminent default on a Non-Designated Mortgage Loan, the Master Servicer or the related Servicer shall dispose of such Mortgaged Property prior to three years after the end of the calendar year of its acquisition by the Trust Fund unless (i) the Trustee and the Trust Administrator shall have been supplied with an Opinion of Counsel to the effect that the holding by the Trust Fund of such Mortgaged Property subsequent to such three-year period will not result in the imposition of taxes on “prohibited transactions” of any REMIC hereunder as defined in section 860F of the Code or cause any REMIC hereunder to fail to qualify as a REMIC at any time that any Certificates are outstanding, in which case the Trust Fund may continue to hold such Mortgaged Property (subject to any conditions contained in such Opinion of Counsel) or (ii) the Master Servicer or the applicable Servicer shall have applied for, prior to the expiration of such three-year period, an extension of such three-year period in the manner contemplated by Section 856(e)(3) of the Code, in which case the three-year period shall be extended by the applicable extension period. Notwithstanding any other provision of this Agreement, no Mortgaged Property acquired by the Trust Fund shall be rented (or allowed to continue to be rented) or otherwise used for the production of income by or on behalf of the Trust Fund in such a manner or pursuant to any terms that would (i) cause such Mortgaged Property to fail to qualify as “foreclosure property” within the meaning of section 860G(a)(8) of the Code or (ii) subject any REMIC hereunder to the imposition of any federal, state or local income taxes on the income earned from such Mortgaged Property under Section 860G(c) of the Code or otherwise, unless the Master Servicer or the related Servicer has agreed to indemnify and hold harmless the Trust Fund with respect to the imposition of any such taxes.

In the event of a default on a Non-Designated Mortgage Loan one or more of whose obligors is not a United States Person, as that term is defined in Section 7701(a)(30) of the Code, in connection with any foreclosure or acquisition of a deed in lieu of foreclosure (together, “foreclosure”) in respect of such Non-Designated Mortgage Loan, the Master Servicer or the related Servicer will cause compliance with the provisions of Treasury Regulation Section 1.1445-2(d)(3) (or any successor thereto) necessary to assure that no withholding tax obligation arises with respect to the proceeds of such foreclosure except to the extent, if any, that proceeds of such foreclosure are required to be remitted to the obligors on such Mortgage Loan.

(d)

The decision of the Master Servicer or a Servicer to foreclose on a defaulted Mortgage Loan shall be subject to a determination by the Master Servicer or such Servicer that the proceeds of such foreclosure would exceed the costs and expenses of bringing such a proceeding. The income earned from the management of any REO Properties, net of reimbursement to the Master Servicer or such Servicer for expenses incurred (including any property or other taxes) in connection with such management and net of applicable accrued and unpaid Master Servicing Fees or Servicing Fees, and unreimbursed Advances and Servicing Advances, shall be applied to the payment of principal of and interest on the related defaulted Non-Designated Mortgage Loans (with interest accruing as though such Non-Designated Mortgage Loans were still current) and all such income shall be deemed, for all purposes in this Agreement, to be payments on account of principal and interest on the related Mortgage Notes and shall be deposited into the related Collection Account. To the extent the net income received during any calendar month is in excess of the amount attributable to amortizing principal and accrued interest at the related Mortgage Rate on the related Non-Designated Mortgage Loan for such calendar month, such excess shall be considered to be a partial prepayment of principal of the related Non-Designated Mortgage Loan.

(e)

The proceeds from any liquidation of a Non-Designated Mortgage Loan, as well as any income from a related REO Property, will be applied in the following order of priority: first, to reimburse the Master Servicer or the related Servicer for any related unreimbursed Servicing Advances and Servicing Fees; second, to reimburse the Master Servicer or such Servicer for any unreimbursed Advances; third, to reimburse the related Collection Account for any Nonrecoverable Advances (or portions thereof) that were previously withdrawn by the Master Servicer or such Servicer pursuant to Section 3.08(a)(iii) that related to such Non-Designated Mortgage Loan; fourth, to accrued and unpaid interest (to the extent no Advance has been made for such amount or any such Advance has been reimbursed) on the Non-Designated Mortgage Loan or related REO Property, at the per annum rate equal to the related Mortgage Rate reduced by the Master Servicing Fee Rate or the related Servicing Fee Rate, and any primary mortgage guaranty insurance fee rate, if applicable, to the Due Date occurring in the month in which such amounts are required to be distributed; and fifth, as a recovery of principal of the Non-Designated Mortgage Loan. Excess proceeds, if any, from the liquidation of a Liquidated Non-Designated Mortgage Loan (“Excess Proceeds”) will be retained by the Master Servicer or the related Servicer as additional servicing compensation pursuant to Section 3.14.

(f)

The Master Servicer and each Servicer of the Non-Designated Mortgage Loans may (but is not obligated to) enter into a special servicing agreement with an unaffiliated holder of a 100% Percentage Interest of the most junior class of Subordinate Certificates, subject to each Rating Agency’s acknowledgment that the Ratings of the Certificates in effect immediately prior to the entering into 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 Holder may (i) instruct the Master Servicer or the related Servicer to commence or delay foreclosure proceedings with respect to delinquent Non-Designated Mortgage Loans and will contain provisions for the deposit of cash with the Master Servicer or such Servicer by the holder that would be available for distribution to Certificateholders if Liquidation Proceeds are less than they otherwise may have been had the Master Servicer or such Servicer acted in accordance with its normal procedures, (ii) purchase delinquent Non-Designated Mortgage Loans from the Trust Fund immediately prior to the commencement of foreclosure proceedings at a price equal to the Purchase Price, and/or (iii) assume all of the servicing rights and obligations with respect to delinquent Non-Designated Mortgage Loans so long as such Holder (A) meets the requirements for a Subservicer set forth in Section 3.02(a), (B) will service such Non-Designated Mortgage Loans in accordance with this Agreement and (C) the Master Servicer or the related Servicer has the right to transfer such servicing rights without the payment of any compensation to a subservicer.

(g)

The Special Servicer, at its option, may (but is not obligated to) purchase from the Trust Fund, (a) any Mortgage Loan that is delinquent in payment 90 or more days or (b) any related Mortgage Loan with respect to which there has been initiated legal action or other proceedings for the foreclosure of the related Mortgaged Property either judicially or non-judicially, in each case, provided that the applicable Servicer has the right to transfer the related servicing rights without the payment of any compensation to a subservicer. Any such purchase shall be made by the Special Servicer with its own funds at a price equal to the Purchase Price for such Mortgage Loan. The applicable Servicer shall be entitled to reimbursement from the Special Servicer for all expenses incurred by it in connection with the transfer of any Mortgage Loan to the Special Servicer pursuant to this Section 3.11(g).

SECTION 3.12

Trustee and Trust Administrator to Cooperate; Release of Mortgage Files.

Upon the payment in full of any Non-Designated Mortgage Loan, or the receipt by the Master Servicer or a Servicer of a notification that payment in full will be escrowed in a manner customary for such purposes, the Master Servicer or such Servicer will immediately notify the Trustee, or the Custodian on its behalf, by delivering, or causing to be delivered a “Request for Release” substantially in the form of Exhibit K. Upon receipt of such request, the Trustee, or the Custodian on its behalf, shall within three Business Days release the related Mortgage File to the Master Servicer or the related Servicer, and the Trustee shall within three Business Days of the Master Servicer’s or such Servicer’s direction execute and deliver to the Master Servicer or such Servicer the request for reconveyance, deed of reconveyance or release or satisfaction of mortgage or such instrument releasing the lien of the Mortgage in each case provided by the Master Servicer or such Servicer, together with the Mortgage Note with written evidence of cancellation thereon. Expenses incurred in connection with any instrument of satisfaction or deed of reconveyance shall be chargeable to the related Mortgagor. From time to time and as shall be appropriate for the servicing or foreclosure of any Non-Designated Mortgage Loan, including for such purpose, collection under any policy of flood insurance, any fidelity bond or errors or omissions policy, or for the purposes of effecting a partial release of any Mortgaged Property from the lien of the Mortgage or the making of any corrections to the Mortgage Note or the Mortgage or any of the other documents included in the Mortgage File, the Trustee, or the Custodian on its behalf within three Business Days of delivery to the Trustee, or the Custodian on its behalf of a Request for Release in the form of Exhibit K signed by a Servicing Officer, release the Mortgage File to the Master Servicer or the related Servicer. Subject to the further limitations set forth below, the Master Servicer or the related Servicer shall cause the Mortgage File or documents so released to be returned to the Trustee, or the Custodian on its behalf, when the need therefor by the Master Servicer or such Servicer no longer exists, unless the Non-Designated Mortgage Loan is liquidated and the proceeds thereof are deposited in the related Collection Account, in which case the Master Servicer or such Servicer shall deliver to the Trustee, or the Custodian on its behalf, a Request for Release in the form of Exhibit K, signed by a Servicing Officer.

If the Master Servicer or a Servicer at any time seeks to initiate a foreclosure proceeding in respect of any Mortgaged Property related to a Non-Designated Mortgage Loan as authorized by this Agreement, the Master Servicer or such Servicer shall deliver or cause to be delivered to the Trustee, for signature, as appropriate, any court pleadings, requests for trustee’s sale or other documents necessary to effectuate such foreclosure or any legal action brought to obtain judgment against the Mortgagor on the Mortgage Note or the Mortgage or to obtain a deficiency judgment or to enforce any other remedies or rights provided by the Mortgage Note or the Mortgage or otherwise available at law or in equity.

SECTION 3.13

Documents, Records and Funds in Possession of the Master Servicer or a Servicer to be Held for the Trustee.

Notwithstanding any other provisions of this Agreement, the Master Servicer and each Servicer shall transmit to the Trustee, or the Custodian on its behalf, as required by this Agreement all documents and instruments in respect of a Non-Designated Mortgage Loan coming into the possession of the Master Servicer or the related Servicer from time to time required to be delivered to the Trustee, or the Custodian on its behalf, pursuant to the terms hereof and shall account fully to the Trust Administrator for any funds received by the Master Servicer or such Servicer or which otherwise are collected by the Master Servicer or such Servicer as Liquidation Proceeds or Insurance Proceeds in respect of any Non-Designated Mortgage Loan. All Mortgage Files and funds collected or held by, or under the control of, the Master Servicer or a Servicer in respect of any Non-Designated Mortgage Loans, whether from the collection of principal and interest payments or from Liquidation Proceeds, including but not limited to, any funds on deposit in a Collection Account, shall be held by the Master Servicer or the related Servicer for and on behalf of the Trustee or the Trust Administrator and shall be and remain the sole and exclusive property of the Trustee, subject to the applicable provisions of this Agreement. The Master Servicer and each Servicer also agrees that it shall not create, incur or subject any Mortgage File or any funds that are deposited in the related Collection Account, Certificate Account or any related Escrow Account, or any funds that otherwise are or may become due or payable to the Trustee or the Trust Administrator for the benefit of the Certificateholders, to any claim, lien, security interest, judgment, levy, writ of attachment or other encumbrance, or assert by legal action or otherwise any claim or right of setoff against any Mortgage File or any funds collected on, or in connection with, a Non-Designated Mortgage Loan, except, however, that the Master Servicer or such Servicer shall be entitled to set off against and deduct from any such funds any amounts that are properly due and payable to the Master Servicer or such Servicer under this Agreement.

SECTION 3.14

Master Servicing Fee and Servicing Fee.

(a)

As compensation for its services hereunder, the Master Servicer and each Servicer shall be entitled to withdraw from the applicable Collection Account or to retain from interest payments on the related Mortgage Loans (which have been remitted to the Master Servicer by the applicable Servicer, other than WMMSC, in the case of the Master Servicer), the amount of the Master Servicing Fee or its Servicing Fee, respectively, for each Mortgage Loan serviced by it, less any amounts in respect of the Master Servicing Fee or its Servicing Fee, as applicable, payable by the Master Servicer or such Servicer pursuant to Section 3.05(c)(vi). The Servicing Fee is limited to, and payable solely from, the interest portion of such Scheduled Payments collected by the Master Servicer or the related Servicer or as otherwise provided in Section 3.08(a). In connection with the servicing of any Special Serviced Mortgage Loan, the Special Servicer shall receive the Servicing Fee for such Special Serviced Mortgage Loan as its compensation and Ancillary Income with respect to Special Serviced Mortgage Loans.

(b)

With respect to each Non-Designated Mortgage Loan, additional servicing compensation in the form of Ancillary Income and Excess Proceeds shall be retained by the Master Servicer or the related Servicer, and additional servicing compensation in the form of Payoff Interest shall be retained by Fairbanks and WMMSC. The Master Servicer and each Servicer shall be required to pay all expenses incurred by it in connection with its servicing activities hereunder (including the payment of any expenses incurred in connection with any Subservicing Agreement entered into pursuant to Section 3.02 and the payment of any premiums for insurance required pursuant to Section 3.18) and shall not be entitled to reimbursement thereof except as specifically provided for in this Agreement.

SECTION 3.15

Access to Certain Documentation.

The Master Servicer and each Servicer shall provide to the OTS and the FDIC and to comparable regulatory authorities supervising Holders of Subordinate Certificates and the examiners and supervisory agents of the OTS, the FDIC and such other authorities, access to the documentation regarding the related Non-Designated Mortgage Loans required by applicable regulations of the OTS and the FDIC. Such access shall be afforded without charge, but only upon reasonable and prior written request and during normal business hours at the offices designated by the Master Servicer or such Servicer. Nothing in this Section shall limit the obligation of the Master Servicer or any Servicer to observe any applicable law prohibiting disclosure of information regarding the Mortgagors and the failure of the Master Servicer or such Servicer to provide access as provided in this Section as a result of such obligation shall not constitute a breach of this Section. Nothing in this Section 3.15 shall require the Master Servicer or any Servicer to collect, create, collate or otherwise generate any information that it does not generate in its usual course of business.

SECTION 3.16

Annual Statement as to Compliance.

SECTION 3.17

Annual Independent Public Accountants’ Servicing Statement; Financial Statements.

Not later than the earlier of (a) March 15 of each calendar year (other than the calendar year during which the Closing Date occurs) or (b) with respect to any calendar year during which the Depositor’s annual report on Form 10-K is required to be filed in accordance with the Exchange Act and the rules and regulations of the Commission, 15 calendar days before each date on which the Depositor’s annual report on Form 10-K is required to be filed in accordance with the Exchange Act and the rules and regulations of the Commission (or if such day is not a Business Day, the immediately preceding Business Day), the Master Servicer and each Servicer at its expense shall cause a nationally or regionally recognized firm of independent public accountants (who may also render other services to such Master Servicer or Servicer, any Seller or any affiliate thereof) which is a member of the American Institute of Certified Public Accountants to furnish a statement to the Trust Administrator, the Depositor and each Servicer, other than WMMSC, shall similarly furnish such a statement to the Master Servicer to the effect that (i) with respect to the Master Servicer and each Servicer other than WMMSC, such firm has examined certain documents and records relating to the servicing of mortgage loans which the Master Servicer or such Servicer is servicing, which may include the related Mortgage Loans or similar mortgage loans, and that, on the basis of such examination, conducted substantially in compliance with the Uniform Single Attestation Program for Mortgage Bankers or the Audit Guide for HUD Approved Title II Approved Mortgagees and Loan Correspondent Programs, nothing has come to their attention which would indicate that such servicing has not been conducted in compliance with Accepted Servicing Practices, except for (a) such exceptions as such firm shall believe to be immaterial, and (b) such other exceptions as shall be set forth in such statement and (ii) with respect to WMMSC as servicer of the WMMSC Serviced Mortgage Loans, in connection with the firm’s examination of the financial statements as of the previous December 31 of WMMSC’s parent corporation (which shall include a limited examination of WMMSC’s financial statements), nothing came to such firm’s attention that indicated that WMMSC was not in compliance with the terms of this Agreement, except for (a) such exceptions as such firm believes to be immaterial, and (b) such other exceptions as are set forth in such statement. In addition each Servicer and the Master Servicer shall disclose to such firm all significant deficiencies relating to such Servicer’s or Master Servicer’s, as applicable, compliance with the minimum servicing standards set forth in this Agreement. In rendering such statement, such firm may rely, as to matters relating to direct servicing of mortgage loans by Subservicers, upon comparable statements for examinations conducted substantially in compliance with the Uniform Single Attestation Program for Mortgage Bankers or the Audit Guide for HUD Approved Title II Approved Mortgagees and Loan Correspondent Programs (rendered within one year of such statement) of independent public accountants with respect to the related Subservicer. Copies of such statement shall be provided by the Trust Administrator to any Certificateholder upon request at the Master Servicer’s or the related Servicer’s expense, provided such statement is delivered by the Master Servicer or such Servicer to the Trust Administrator.

SECTION 3.18

Maintenance of Fidelity Bond and Errors and Omissions Insurance.

The Master Servicer and each Servicer shall maintain with responsible companies, at its own expense, a blanket Fidelity Bond and an Errors and Omissions Insurance Policy, with broad coverage on all officers, employees or other persons acting in any capacity requiring such persons to handle funds, money, documents or papers relating to the related Mortgage Loans (in the case of a Servicer, “Servicer Employees,” and in the case of the Master Servicer, “Master Servicing Employees”). Any such Fidelity Bond and Errors and Omissions Insurance Policy shall be in the form of the Mortgage Banker’s Blanket Bond and shall protect and insure the Master Servicer or the related Servicer against losses, including forgery, theft, embezzlement, fraud, errors and omissions and negligent acts of the Master Servicer Employees, in the case of the Master Servicer, or such Servicer Employees, in the case of a Servicer. Such Fidelity Bond and Errors and Omissions Insurance Policy also shall protect and insure the Master Servicer and each Servicer against losses in connection with the release or satisfaction of a related Mortgage Loan without having obtained payment in full of the indebtedness secured thereby. No provision of this Section 3.18 requiring such Fidelity Bond and Errors and Omissions Insurance Policy shall diminish or relieve the Master Servicer or a Servicer from its duties and obligations as set forth in this Agreement. The minimum coverage under any such bond and insurance policy shall be at least equal to the corresponding amounts required by FNMA. Upon the request of the Trust Administrator, the Master Servicer or the related Servicer shall cause to be delivered to the Trust Administrator a certificate of insurance of the insurer and the surety including a statement from the surety and the insurer that such fidelity bond and insurance policy shall in no event be terminated or materially modified without 30 days’ prior written notice to the Trust Administrator.

SECTION 3.19

Special Serviced Mortgage Loans.

If directed by the Special Servicer and solely at the Special Servicer’s option, the Master Servicer or a Servicer other than WMMSC and WMBFA (a “Transferring Servicer”) shall transfer the servicing of any Non-Designated Mortgage Loan serviced by the Transferring Servicer 90 days or more delinquent to the Special Servicer. The Special Servicer shall thereupon assume all of the rights and obligations of the Transferring Servicer hereunder arising thereafter and the Transferring Servicer shall have no further rights or obligations hereunder with respect to such Non-Designated Mortgage Loan (except that the Special Servicer shall not be (i) liable for losses of the Transferring Servicer pursuant to Section 3.09 hereof or for any acts or omissions of the Transferring Servicer hereunder prior to the servicing transfer date, (ii) obligated to effectuate repurchases or substitutions of Non-Designated Mortgage Loans hereunder including, but not limited to, repurchases or substitutions of Non-Designated Mortgage Loans pursuant to Section 2.02 or 2.03 hereof or (iii) deemed to have made any representations and warranties of a Transferring Servicer hereunder). Upon the transfer of the servicing of any such Non-Designated Mortgage Loan to the Special Servicer, the Special Servicer shall be entitled to the Servicing Fee and other compensation accruing after the servicing transfer date with respect to such Mortgage Loans pursuant to Section 3.14.

In connection with the transfer of the servicing of any Non-Designated Mortgage Loan to the Special Servicer, the Transferring Servicer shall, at the Special Servicer’s expense, deliver to the Special Servicer all documents and records relating to such Non-Designated Mortgage Loans and an accounting of amounts collected or held by it and otherwise use its best efforts to effect the orderly and efficient transfer of the servicing to the Special Servicer. On the servicing transfer date, the Special Servicer shall reimburse the Transferring Servicer for all unreimbursed Advances, Servicing Advances and Servicing Fees and Master Servicing Fees, as applicable, relating to the Non-Designated Mortgage Loans for which the servicing is being transferred. The Special Servicer shall be entitled to be reimbursed pursuant to Section 3.08 or otherwise pursuant to this Agreement for all such Advances, Servicing Advances and Servicing Fees and Master Servicing Fees, as applicable, paid by the Transferring Servicer pursuant to this Section 3.19. In addition, the Special Servicer shall amend the Non-Designated Mortgage Loan Schedule to reflect that such Non-Designated Mortgage Loans are Special Serviced Mortgage Loans.

SECTION 4.07

Cross-Collateralization; Adjustments to Available Funds

(a)

On each Distribution Date prior to the Credit Support Depletion Date, but after the date on which the aggregate Class Principal Balance of the Group I, Group II or Group III Certificates has been reduced to zero, the Trust Administrator shall distribute the principal portion of Available Distribution Amount on the Mortgage Loans relating to such Senior Certificates that will have been paid in full, to the holders of the Senior Certificates of the other Certificate Group(s). Such amount will be allocated between the other Groups, pro rata, based on aggregate Class Principal Balance of the related Senior Certificates and paid the Senior Certificates in each such Group in the same priority as such Certificates would receive other distributions of principal pursuant to Section 4.01(I)(A); provided, however, that the Trust Administrator shall not make such distribution on such Distribution Date if (a) the Group C-B Percentage for such Distribution Date is greater than or equal to 200% of such Group C-B Percentage as of the Closing Date and (b) the average outstanding principal balance of the Mortgage Loans in each Loan Group delinquent 60 days or more over the last six months, as a percentage of the related Subordinate Component Balance, is less than 50%.

(b)

If on any Distribution Date the aggregate Class Principal Balance of the Group I, Group II or Group III Certificates is greater than the aggregate Stated Principal Balance of the Mortgage Loans in the related Loan Group (the “Undercollateralized Group”), then the Trust Administrator shall reduce the Available Distribution Amount of the other Loan Group(s) that is not undercollateralized (each, an “Overcollateralized Group”), as follows:

(1)

to add to the Available Distribution Amount of the Undercollateralized Group(s) an amount equal to the lesser of (a) one month's interest on the Principal Transfer Amount of the Undercollateralized Group(s) at the Net WAC Rate (without giving effect to any reduction for any Excess Interest Rate) applicable to the Undercollateralized Group(s) and (b) Available Distribution Amount of the Overcollateralized Group remaining after making interest distributions to the Senior Certificates of the Overcollateralized Group(s) on such Distribution Date pursuant to Section 4.01; and

(2)

to the Senior Certificates of each Undercollateralized Group, to the extent of the principal portion of Available Distribution Amount of the Overcollateralized Group(s) remaining after making interest and principal distributions to the Senior Certificates of the Overcollateralized Group(s) on such Distribution Date pursuant to Section 4.01, until the Class Principal Balance of the Senior Certificates of such Undercollateralized Group(s) equals the aggregate Stated Principal Balance of the Mortgage Loans in the related Loan Group(s). Payments shall be made to the Senior Certificates in each Group in the same priority as such Certificates would receive other distributions of principal pursuant to Section 4.01(I)(A).

(c)

If more than one Overcollateralized Group exists on any Distribution Date, reductions in the Available Distribution Amount of such Groups to make the payments required to be made pursuant to Section 4.07(b) on such Distribution Date shall be made pro rata, based on the amount of payments required to be made to the Undercollateralized Group(s). If more than one Undercollateralized Group exists on any Distribution Date, payments made to such Groups from the Available Distribution Amount of the Overcollateralized Group shall be made pro rata, based on the amount of payments required to be made to the Undercollateralized Group(s).

SECTION 4.08

On the Closing Date, the Trust Administrator shall establish and maintain in its name, in trust for the benefit of the Holders of the Certificates, the Basis Risk Reserve Fund. The Basis Risk Reserve Fund shall be an Eligible Account, and funds on deposit therein shall be held separate and apart from, and shall not be commingled with, any other moneys, including without limitation, other moneys held by the Trust Administrator pursuant to this Agreement.

(b)

On the Closing Date, $5,000 will be deposited by the Depositor in the Basis Risk Reserve Fund. On each Distribution Date, the Trust Administrator shall transfer from the Certificate Account to the Basis Risk Reserve Fund pursuant to Section 4.01(II)(d)(vii), the Required Basis Risk Reserve Fund Deposit. Amounts on deposit in the Basis Risk Reserve Fund can be withdrawn by the Trust Administrator in connection with any Distribution Date to fund the amounts required to be distributed to holders of the Group IV Certificates in respect of Basis Risk Shortfalls. On any Distribution Date, any amounts on deposit in the Basis Risk Reserve Fund in excess of the Required Basis Risk Reserve Fund Amount shall be distributed to the Class IV-X Certificateholders pursuant to Section 4.01(II)(d)(viii).

(c)

Funds in the Basis Risk Reserve Fund may be invested in Eligible Investments by the Trust Administrator at the direction of the holders of the Class IV-X Certificateholders. Any net investment earnings on such amounts shall be payable to the Class IV-X Certificateholders. The Class IV-X Certificateholders shall evidence ownership of the Basis Risk Reserve Fund for federal tax purposes and the Class IV-X Certificateholders shall direct the Trust Administrator in writing as to the investment of amounts therein. In the absence of such written direction, all funds in the Basis Risk Reserve Fund shall be invested by the Trust Administrator in the JPMorgan Prime Money Market Fund. The Trust Administrator shall have no liability for losses on investments in Eligible Investments made pursuant to this Section 4.08(c) (other than as obligor on any such investments). Upon termination of the Trust Fund, any amounts remaining in the Basis Risk Reserve Fund shall be distributed to the Class IV-X Certificateholders.

(d)

If the Trust Administrator shall deposit in the Basis Risk Reserve Fund any amount not required to be deposited therein, it may at any time withdraw such amount from the Basis Risk Reserve Fund, any provision herein to the contrary notwithstanding.

(e)

On the Distribution Date immediately after the Distribution Date on which the aggregate Class Principal Balance of the Class IV-A-1, Class IV-M-1 and Class IV-M-2 Certificates equals zero, any amounts on deposit in the Basis Risk Reserve Fund not payable on such Certificates shall be deposited into the Certificate Account and distributed to the Holders of the Class IV-X Certificates in the same manner as if distributed pursuant to Section 4.01(II)(d)(viii) hereof.

With respect to any Non-Designated Mortgage Loan, the Master Servicer and each Servicer shall deposit in the related Collection Account as Advances an amount equal to all Scheduled Payments (with interest at the Mortgage Rate less the Servicing Fee Rate and any applicable Master Servicing Fee Rate) which were due on the Non-Designated Mortgage Loans serviced by it during the applicable Collection Period and which were delinquent at the close of business on the immediately preceding Determination Date. The Master Servicer and each Servicer’s obligation to make such Advances as to any related Non-Designated Mortgage Loan will continue through the last Scheduled Payment due prior to the payment in full of such Non-Designated Mortgage Loan, or through the date that the related Mortgaged Property has, in the judgment of the Master Servicer and the related Servicer, been completely liquidated.

With respect to any Non-Designated Mortgage Loan, to the extent required by Accepted Servicing Practices, the Master Servicer and each Servicer shall be obligated to make Advances in accordance with the provisions of this Agreement; provided, however, that such obligation with respect to any related Non-Designated Mortgage Loan shall cease if the Master Servicer or a Servicer determines, in its reasonable opinion, that Advances with respect to such Non-Designated Mortgage Loan are Nonrecoverable Advances. In the event that the Master Servicer or such Servicer determines that any such Advances are Nonrecoverable Advances, the Master Servicer or such Servicer shall provide the Trust Administrator and the Trustee with a certificate signed by a Servicing Officer evidencing such determination.

With respect to any Non-Designated Mortgage Loan, if the amount of Advances received from a Servicer, other than WMMSC, is less than the amount required to be advanced by such Servicer, the Master Servicer shall be obligated to make a payment in an amount equal to such deficiency, subject to any determination by the Master Servicer that any portion of the amount required to be advanced is a Nonrecoverable Advance.

With respect to any Designated Mortgage Loan, the Master Servicer shall deposit in its Collection Account as Advances: (i) with respect to the Bank One Mortgage Loans, an amount equal to the amount of Monthly Advances (as defined in the Bank One Servicing Agreement) required to be remitted to the Master Servicer by the related Designated Servicer pursuant to Section 5.03 of the Bank One Servicing Agreement, (ii) with respect to the Xxxxxx Mortgage Loans, an amount equal to the amount of Monthly Advances (as defined in the Xxxxxx Servicing Agreement) required to be remitted to the Master Servicer by the related Designated Servicer pursuant to Section 5.03 of the Xxxxxx Servicing Agreement, (iii) with respect to the National City Mortgage Loans, an amount equal to the amount of Monthly Advances (as defined in the National City Servicing Agreement) required to be remitted to the Master Servicer by the related Designated Servicer pursuant to Section 5.03 of the National City Servicing Agreement and (iv) with respect to the Nexstar Mortgage Loans, an amount equal to the amount of Monthly Advances (as defined in the Nexstar Servicing Agreement) required to be remitted to the Master Servicer by the related Designated Servicer pursuant to Section 11.14 of the Nexstar Servicing Agreement.

With respect to any Non-Designated Mortgage Loan, if an Advance is required to be made hereunder, the Master Servicer or the related Servicer shall on the Cash Remittance Date either (i) deposit in the Collection Account from its own funds an amount equal to such Advance, (ii) cause to be made an appropriate entry in the records of the Collection Account that funds in such account being held for future distribution or withdrawal have been, as permitted by this Section 5.01, used by the Master Servicer or such Servicer to make such Advance or (iii) make Advances in the form of any combination of clauses (i) and (ii) aggregating the amount of such Advance. Any such funds being held in a Collection Account for future distribution and so used shall be replaced by the Master Servicer or such Servicer from its own funds by deposit in such Collection Account on or before any future Distribution Date in which such funds would be due.

The Certificates shall be issuable in registered form, in the minimum denominations, integral multiples in excess thereof (except that one Certificate in each Class may be issued in a different amount which must be in excess of the applicable minimum denomination) and aggregate denominations per Class set forth in the Preliminary Statement.

Subject to Section 11.02 respecting the final distribution on the Certificates, on each Distribution Date the Trust Administrator shall make distributions to each Certificateholder of record on the preceding Record Date either (x) by wire transfer in immediately available funds to the account of such holder at a bank or other entity having appropriate facilities therefore, if (i) such Holder has so notified the Trust Administrator at least five Business Days prior to the related Record Date and (ii) such Holder shall hold (A) a Notional Amount Certificate, (B) 100% of the Class Principal Balance of any Class of Certificates or (c) Certificates of any Class with aggregate principal Denominations of not less than $1,000,000 or (y) by check mailed by first class mail to such Certificateholder at the address of such holder appearing in the Certificate Register.

The Certificates shall be executed by manual or facsimile signature on behalf of the Trust Administrator by a Responsible Officer. Certificates bearing the manual or facsimile signatures of individuals who were, at the time when such signatures were affixed, authorized to sign on behalf of the Trust Administrator shall bind the Trust Administrator, notwithstanding that such individuals or any of them have ceased to be so authorized prior to the authentication and delivery of such Certificates or did not hold such offices at the date of such Certificate. 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 executed by the Trust Administrator by manual signature, and such certificate of authentication 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.

SECTION 6.02

Registration of Transfer and Exchange of Certificates.

(a)

The Trust Administrator shall maintain, or cause to be maintained, a Certificate Register in which, subject to such reasonable regulations as it may prescribe, the Trust Administrator shall provide for the registration of Certificates and of transfers and exchanges of Certificates as herein provided. Upon surrender for registration of transfer of any Certificate, the Trust Administrator shall execute, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates in like aggregate interest and of the same Class.

(b)

At the option of a Certificateholder, Certificates may be exchanged for other Certificates of authorized denominations and the same aggregate interest in the Trust Fund and of the same Class, upon surrender of the Certificates to be exchanged at the office or agency of the Trust Administrator set forth in Section 6.06. Whenever any Certificates are so surrendered for exchange, the Trust Administrator shall execute, authenticate and deliver the Certificates which the Certificateholder making the exchange is entitled to receive. Every Certificate presented or surrendered for registration of transfer or exchange shall be accompanied by a written instrument of transfer in form satisfactory to the Trust Administrator duly executed by the Holder thereof or his attorney duly authorized in writing.

(c)

No service charge to the Certificateholders shall be made for any registration of transfer or exchange of Certificates, but payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any transfer or exchange of Certificates may be required.

(d)

All Certificates surrendered for registration of transfer and exchange shall be canceled and subsequently destroyed by the Trust Administrator in accordance with the Trust Administrator’s customary procedures.

(e)

No transfer of any Private Certificate shall be made unless that transfer is made pursuant to an effective registration statement under the 1933 Act and effective registration or qualification under applicable state securities laws, or is made in a transaction which does not require such registration or qualification. Except in connection with any transfer of a Private Certificate by the Depositor to any affiliate, in the event that a transfer is to be made in reliance upon an exemption from the 1933 Act and such laws, in order to assure compliance with the 1933 Act and such laws, the Certificateholder desiring to effect such transfer and such Certificateholder’s prospective transferee shall each certify to the Trust Administrator in writing the facts surrounding the transfer in substantially the form set forth in Exhibit L (the “Transferor Certificate”) and (i) deliver a letter in substantially the form of either (A) Exhibit M 1 (the “Investment Letter”), provided that all of the Private Certificates of a Class shall be transferred to one investor or the Depositor otherwise consents to such transfer, or (B) Exhibit M 2 (the “Rule 144A Letter”) or (ii) there shall be delivered to the Trust Administrator at the expense of the transferor an Opinion of Counsel that such transfer may be made pursuant to an exemption from the 1933 Act. The Depositor shall provide to any Holder of a Private Certificate and any prospective transferee designated by any such Holder, information regarding the related Certificates and the Mortgage Loans and such other information as shall be necessary to satisfy the condition to eligibility set forth in Rule 144A(d)(4) for transfer of any such Certificate without registration thereof under the 1933 Act pursuant to the registration exemption provided by Rule 144A. The Trust Administrator shall cooperate with the Depositor in providing the Rule 144A information referenced in the preceding sentence, including providing to the Depositor such information regarding the Certificates, the Mortgage Loans and other matters regarding the Trust Fund as the Depositor shall reasonably request to meet its obligation under the preceding sentence. Each Holder of a Private Certificate desiring to effect such transfer shall, and does hereby agree to, indemnify the Trust Administrator, the Depositor, each Seller, the Master Servicer, each Servicer and the Special Servicer against any liability that may result if the transfer is not so exempt or is not made in accordance with such federal and state laws.

(f)

No transfer of an ERISA-Restricted Certificate shall be made unless the Trustee shall have received in accordance with Exhibit X-0, Xxxxxxx X-0 or Exhibit N, as applicable, either (i) a representation letter from the transferee of such Certificate, acceptable to and in form and substance satisfactory to the Trustee, to the effect that such transferee is not an employee benefit plan or arrangement subject to Section 406 of ERISA or Section 4975 of the Code, or a person using the assets of any such plan or arrangement, which representation letter shall not be an expense of the Trustee or the Trust Fund, (ii) if the purchaser is an insurance company and the Certificate has been the subject of an ERISA-Qualifying Underwriting, a representation that the purchaser is an insurance company which is purchasing such Certificates with funds contained in an “insurance company general account” (as such term is defined in Section V(e) of Prohibited Transaction Class Exemption 95-60 (“PTCE 95-60”)) and that the purchase and holding of such Certificates are covered under Sections I and III of PTCE 95-60 or (iii) in the case of any such Certificate presented for registration in the name of an employee benefit plan or arrangement subject to ERISA or Section 4975 of the Code (or comparable provisions of any subsequent enactments), or a person using such plan’s or arrangement’s assets, an Opinion of Counsel satisfactory to the Trustee to the effect that the purchase or holding of such Certificate will not result in prohibited transactions under Section 406 of ERISA and/or Section 4975 of the Code and will not subject the Depositor, the Trustee, the Trust Administrator, the Master Servicer or any other Servicer to any obligation in addition to those undertaken in this Agreement, which Opinion of Counsel shall not be an expense of such parties or the Trust Fund. In the event the representations referred to in the preceding sentence are not furnished, such representations shall be deemed to have been made to the trustee by the transferee’s acceptance of an ERISA-Restricted Certificate by any beneficial owner who purchases an interest in such Certificate in book-entry form. In the event that a representation is violated, or any attempt to transfer an ERISA- Restricted Certificate to a plan or arrangement or person using a plan’s or arrangement’s assets is attempted without the delivery to the Trustee of the Opinion of Counsel described above, the attempted transfer or acquisition of such Certificate shall be void and of no effect.

(g)

Additional restrictions on transfers of the Class AR Certificates to Disqualified Organizations are set forth below:

(i) Each Person who has or who acquires any ownership interest in a Class AR 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 Trust Administrator 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 Class AR Certificate are expressly subject to the following provisions:

(A)

Each Person holding or acquiring any ownership interest in a Class AR Certificate shall be other than a Disqualified Organization and shall promptly notify the Trust Administrator of any change or impending change in its status as other than a Disqualified Organization.

(B)

In connection with any proposed transfer of any ownership interest in a Class AR Certificate to a U.S. Person, the Trust Administrator shall require delivery to it, and shall not register the transfer of a Class AR Certificate until its receipt of (1) an affidavit and agreement (a “Transferee Affidavit and Agreement” attached hereto as Exhibit N) from the proposed transferee, in form and substance satisfactory to the Trust Administrator, representing and warranting, among other things, that it is not a non U.S. Person, that such transferee is other than a Disqualified Organization, that it is not acquiring its ownership interest in a Class AR Certificate that is the subject of the proposed Transfer as a nominee, trustee or agent for any Person who is not other than a Disqualified Organization, that for so long as it retains its ownership interest in a Class AR Certificate, it will endeavor to remain other than a Disqualified Organization, and that it has reviewed the provisions of this Section 6.02(g) and agrees to be bound by them, and (2) a certificate, attached hereto as Exhibit O, from the Holder wishing to transfer a Class AR Certificate, in form and substance satisfactory to the Trust Administrator, 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 Trust Administrator has actual knowledge that the proposed transferee is not other than a Disqualified Organization, no transfer of an ownership interest in a Class AR Certificate to such proposed transferee shall be effected.

(D)

Each Person holding or acquiring any ownership interest in a Class AR Certificate agrees, by holding or acquiring such ownership interest, to require a Transferee Affidavit and Agreement from the other Person to whom such Person attempts to transfer its ownership interest and to provide a certificate to the Trust Administrator in the form attached hereto as Exhibit O.

(ii) The Trust Administrator shall register the transfer of any Class AR 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 O and all of such other documents as shall have been reasonably required by the Trust Administrator as a condition to such registration.

(iii) (A)

If any Disqualified Organization shall become a Holder of a Class AR Certificate, then the last preceding Holder that was other than a Disqualified Organization 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 Class AR Certificate. If any non U.S. Person shall become a Holder of a Class AR Certificate, then the last preceding Holder that 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 Class AR Certificate. If a transfer of a Class AR Certificate is disregarded pursuant to the provisions of Treasury Regulations Section 1.860E 1 or Section 1.860G 3, then the last preceding Holder that was other than a Disqualified Organization 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 Class AR Certificate. The Trust Administrator shall be under no liability to any Person for any registration of transfer of a Class AR Certificate that is in fact not permitted by this Section 6.02(g) 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 of a Class AR Certificate shall become a Holder of a Class AR Certificate in violation of the restrictions in this Section 6.02(g) and to the extent that the retroactive restoration of the rights of the Holder of such Class AR Certificate as described in clause (iii)(A) above shall be invalid, illegal or unenforceable, then the Depositor shall have the right, without notice to the Holder or any prior Holder of such Class AR Certificate, to sell such Class AR Certificate to a purchaser selected by the Depositor on such terms as the Depositor may choose. Such purported transferee shall promptly endorse and deliver a Class AR Certificate in accordance with the instructions of the Depositor. Such purchaser may be the Depositor itself or any affiliate of the Depositor. The proceeds of such sale, net of the commissions (which may include commissions payable to the Depositor or its affiliates), expenses and taxes due, if any, shall be remitted by the Depositor 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 Depositor, and the Depositor shall not be liable to any Person having an ownership interest or a purported ownership interest in a Class AR Certificate as a result of its exercise of such discretion.

(iv) The Master Servicer and each Servicer, on behalf of the Trust Administrator, shall make available, upon written request from the Trust Administrator, all information reasonably available to it that is necessary to compute any tax imposed (A) as a result of the transfer of an ownership interest in a Class AR Certificate to any Person who is not other than a Disqualified Organization, including the information regarding “excess inclusions” of such Residual Certificate 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 other than a Disqualified Organization. Reasonable compensation for providing such information may be required by the Master Servicer or the related Servicer from such Person.

(v) The provisions of this Section 6.02(g) set forth prior to this Section (v) may be modified, added to or eliminated by the Depositor, provided that there shall have been delivered to the Trust Administrator the following:

(A)

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

(B)

a certificate of the Depositor stating that the Depositor has received an Opinion of Counsel, in form and substance satisfactory to the Depositor, to the effect that such modification, addition to or elimination of such provisions will not cause the Trust Fund to cease to qualify as a REMIC and will not create a risk that (i) the Trust Fund may be subject to an entity level tax caused by the transfer of a Class AR Certificate to a Person which is not other than a Disqualified Organization or (2) a Certificateholder or another Person will be subject to a REMIC related tax caused by the transfer of applicable Class AR Certificate to a Person which is not other than a Disqualified Organization.

(vi) The following legend shall appear on each Class AR Certificate:

ANY RESALE, TRANSFER OR OTHER DISPOSITION OF THIS CERTIFICATE MAY BE MADE ONLY IF THE PROPOSED TRANSFEREE PROVIDES A TRANSFER AFFIDAVIT TO THE DEPOSITOR AND THE TRUST ADMINISTRATOR THAT (1) SUCH TRANSFEREE IS NOT (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 AR 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 AR CERTIFICATE BY ACCEPTANCE OF THIS CERTIFICATE SHALL BE DEEMED TO HAVE CONSENTED TO THE PROVISIONS OF THIS PARAGRAPH.

(h)

The Trust Administrator shall have no liability to the Trust Fund arising from a transfer of any such Certificate in reliance upon a certification, ruling or Opinion of Counsel described in this Section 6.02; provided, however, that the Trust Administrator shall not register the transfer of any Class AR Certificate if it has actual knowledge that the proposed transferee does not meet the qualifications of a permitted Holder of a Class AR Certificate as set forth in this Section 6.02.

SECTION 6.03

Mutilated, Destroyed, Lost or Stolen Certificates.

If (a) any mutilated Certificate is surrendered to the Trust Administrator, or the Trust Administrator receives evidence to its satisfaction of the destruction, loss or theft of any Certificate and (b) there is delivered to each Servicer, the Trustee and the Trust Administrator such security or indemnity as may be required by them to save each of them harmless, then, in the absence of notice to the Trustee and the Trust Administrator that such Certificate has been acquired by a bona fide purchaser, the Trust Administrator shall execute, authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a new Certificate of like tenor and interest in the Trust Fund. In connection with the issuance of any new Certificate under this Section 6.03, the Trust Administrator 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 Trust Administrator) connected therewith. Any replacement Certificate issued pursuant to this Section 6.03 shall constitute complete and indefeasible evidence of ownership in the Trust Fund, as if originally issued, whether or not the lost, stolen or destroyed Certificate shall be found at any time.

SECTION 6.04

Persons Deemed Owners.

Prior to due presentation of a Certificate for registration of transfer, each Servicer, the Trust Administrator, and any agent of the Master Servicer or any Servicer, the Trust Administrator may treat the person in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions as provided in this Agreement and for all other purposes whatsoever, and none of the Master Servicer or the Servicers, the Trust Administrator, nor any agent of the Master Servicer or a Servicer or the Trust Administrator shall be affected by any notice to the contrary.

SECTION 6.05

Access to List of Certificateholders’ Names and Addresses.

(a)

If three or more Certificateholders (i) request in writing from the Trust Administrator a list of the names and addresses of Certificateholders, (ii) state that such Certificateholders desire to communicate with other Certificateholders with respect to their rights under this Agreement or under the Certificates and (iii) provide a copy of the communication which such Certificateholders propose to transmit, then the Trust Administrator shall, within ten Business Days after the receipt of such request, afford such Certificateholders access during normal business hours to a current list of the Certificateholders. The expense of providing any such information requested by a Certificateholder shall be borne by the Certificateholders requesting such information and shall not be borne by the Trust Administrator or the Trustee. Every Certificateholder, by receiving and holding a Certificate, agrees that the Trustee and the Trust Administrator shall not be held accountable by reason of the disclosure of any such information as to the list of the Certificateholders hereunder, regardless of the source from which such information was derived.

(b)

The Master Servicer and each Servicer, so long as it is a servicer hereunder, DLJMC and the Depositor shall have unlimited access to a list of the names and addresses of the Certificateholders which list shall be provided by the Trust Administrator promptly upon request.

SECTION 6.06

Maintenance of Office or Agency.

The Trust Administrator will maintain or cause to be maintained at its expense an office or offices or agency or agencies in New York City where Certificates may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Trust Administrator in respect of the Certificates and this Agreement may be served. The Trust Administrator initially designates its Corporate Trust Office as its office for such purpose. The Trust Administrator will give prompt written notice to the Certificateholders of any change in the location of any such office or agency.

SECTION 6.07

Book Entry Certificates.

Notwithstanding the foregoing, the Book-Entry Certificates, upon original issuance, shall be issued in the form of one or more typewritten Certificates representing the Book-Entry Certificates, to be delivered to DTC, the initial Clearing Agency, by, or on behalf of, the Depositor. 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 will receive a definitive certificate representing such Beneficial Holder’s interest in the Certificates, except as provided in Section 6.09. Unless and until definitive, fully registered Certificates (“Definitive Certificates”) have been issued to the Beneficial Holders pursuant to Section 6.09:

(a)

the provisions of this Section 6.07 shall be in full force and effect with respect to the Book-Entry Certificates;

(b)

the Depositor and the Trust Administrator may deal with the Clearing Agency for all purposes with respect to the Book-Entry Certificates (including the making of distributions on such Certificates) as the sole Holder of such Certificates;

(c)

to the extent that the provisions of this Section 6.07 conflict with any other provisions of this Agreement, the provisions of this Section 6.07 shall control; and

(d)

the rights of the Beneficial Holders of the Book-Entry Certificates shall be exercised only through the Clearing Agency and the Participants and shall be limited to those established by law and agreements between such Beneficial Holders and the Clearing Agency and/or the Participants. Pursuant to the Depository Agreement, unless and until Definitive Certificates are issued pursuant to Section 6.09, the initial Clearing Agency will make book-entry transfers among the Participants and receive and transmit distributions of principal and interest on the related Book-Entry Certificates to such Participants.

For purposes of any provision of this Agreement requiring or permitting actions with the consent of, or at the direction of, Holders of the Book-Entry Certificates evidencing a specified percentage of the aggregate unpaid principal amount of such Certificates, such direction or consent may be given by the Clearing Agency at the direction of Beneficial Holders owning such Certificates evidencing the requisite percentage of principal amount of such 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 6.08

Notices to Clearing Agency.

Whenever notice or other communication to the Holders of Book-Entry Certificates is required under this Agreement, unless and until Definitive Certificates shall have been issued to the related Certificateholders pursuant to Section 6.09, the Trust Administrator 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 Participants in accordance with its applicable rules, regulations and procedures.

SECTION 6.09

Definitive Certificates.

If (a) the Depositor advises the Trust Administrator in writing that the Clearing Agency is no longer willing or able to properly discharge its responsibilities under the Depository Agreement with respect to the Certificates and the Trust Administrator or the Depositor is unable to locate a qualified successor, (b) the Depositor, at its option, advises the Trust Administrator 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, Holders of Book-Entry Certificates evidencing not less than 66-2/3% of the aggregate Class Principal Balance of the Book-Entry Certificates advise the Trust Administrator in writing that the continuation of a book-entry system with respect to the such Certificates through the Clearing Agency is no longer in the best interests of the Holders of such Certificates with respect to the Book-Entry Certificates, the Trust Administrator shall notify all Holders of such Certificates of the occurrence of any such event and the availability of Definitive Certificates. Upon surrender to the Trust Administrator of the such Certificates by the Clearing Agency, accompanied by registration instructions from the Clearing Agency for registration, the Trust Administrator shall authenticate and deliver the Definitive Certificates. Neither the Depositor nor the Trust Administrator 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 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 Trust Administrator, to the extent applicable with respect to such Definitive Certificates, and the Trust Administrator shall recognize the Holders of Definitive Certificates as Certificateholders hereunder.

SECTION 7.03

Limitation on Liability of the Sellers, the Depositor, the Master Servicer, the Servicers, the Special Servicer and Others.

None of the Depositor, the Master Servicer, any Servicer, any Seller, the Special Servicer, nor any of the directors, officers, employees or agents of the Depositor, the Master Servicer, any Servicer, any Seller or the Special Servicer shall be under any liability to the Certificateholders for any action taken or for refraining from the taking of any action in good faith pursuant to this Agreement, or for errors in judgment; provided, however, that this provision shall not protect the Depositor, the Master Servicer, any Servicer, any Seller or the Special Servicer against any breach of representations or warranties made by it herein or protect the Depositor, the Master Servicer, any Servicer, any Seller or the Special Servicer or any such director, officer, employee or agent from any liability which would otherwise be imposed by reasons of willful misfeasance, bad faith or gross negligence in the performance of duties or by reason of reckless disregard of obligations and duties hereunder. The Depositor, the Master Servicer, any Servicer, any Seller and the Special Servicer and any director, officer, employee or agent of the Depositor, the Master Servicer, any Servicer, any Seller or the Special Servicer may rely in good faith on any document of any kind prima facie properly executed and submitted by any Person respecting any matters arising hereunder. The Depositor, the Master Servicer, any Servicer, any Seller and the Special Servicer and any director, officer, employee or agent of the Depositor, the Master Servicer, any Servicer, any Seller or the Special Servicer shall be indemnified by the Trust Fund and held harmless against any loss, liability or expense incurred in connection with any legal action relating to this Agreement or the Certificates, other than any loss, liability or expense incurred by reason of willful misfeasance, bad faith or gross negligence in the performance of duties hereunder or by reason of reckless disregard of obligations and duties hereunder. None of the Depositor, the Master Servicer, any Servicer, any Seller or the Special Servicer shall be under any obligation to appear in, prosecute or defend any legal action that is not incidental to their respective duties hereunder and which in its opinion may involve it in any expense or liability; provided, however, that the Depositor, the Master Servicer, any Servicer, any Seller or the Special Servicer may in its discretion undertake any such action that it may deem necessary or desirable in respect of this Agreement and the rights and duties of the parties hereto and interests of the Trustee, the Trust Administrator and the Certificateholders hereunder; provided, however, that in the event the related Servicer (other than WMMSC) agrees, at the request of any Seller (other than WMMSC), to act on behalf of such Seller in any dispute or litigation that is not incidental to such Servicer’s duties hereunder and that relates to the origination of a Mortgage Loan, such Seller shall pay all expenses associated with the management and defense of such claim. Anything in this Agreement to the contrary notwithstanding, in no event shall the Master Servicer or any Servicer or the Special Servicer be liable for special, indirect or consequential loss or damage of any kind whatsoever (including but not limited to lost profits), even if the Master Servicer or the related Servicer or the Special Servicer has been advised of the likelihood of such loss or damage and regardless of the form of action.

SECTION 7.04

Master Servicer and Servicer Not to Resign; Transfer of Servicing.

Neither the Master Servicer nor any Servicer shall resign from the obligations and duties hereby imposed on it except (i) upon appointment of a successor master servicer or successor servicer and receipt by the Trustee and the Trust Administrator of a letter from each Rating Agency that such a resignation and appointment will not result in a downgrading of the rating of any of the Certificates related to the applicable Mortgage Loans, or (ii) upon determination that its duties hereunder are no longer permissible under applicable law. Any such determination under clause (ii) permitting the resignation of the Master Servicer or a Servicer shall be evidenced by an Opinion of Counsel to such effect delivered to the Trustee and the Trust Administrator. No such resignation shall become effective until the successor master servicer or successor servicer shall have assumed the Master Servicer or such Servicer’s, as applicable, responsibilities, duties, liabilities and obligations hereunder in accordance with Section 8.02 hereof.

(b)

Notwithstanding the foregoing, DLJMC or its transferee shall be entitled to request that the Master Servicer resign and appoint a successor master servicer; provided that such entity delivers to the Trustee, the Trust Administrator and the Master Servicer the letter required in Section 7.04(a)(i) above. Notwithstanding the foregoing, at DLJMC’s request, Fairbanks shall resign upon DLJMC’s selection and appointment of a successor servicer; provided that DLJMC delivers to the Trustee, the Trust Administrator and the Master Servicer the letter required in Section 7.04(a)(i) above.

(c)

Notwithstanding anything to the contrary in this Agreement, servicing with respect to all or a portion of the Eligible Servicing Transfer Loans may be transferred to WMMSC under this Agreement upon written notice being delivered to the Trustee, CMMC, the Depositor, DLJMC and the Trust Administrator. Any transfer of servicing with respect to such Eligible Servicing Transfer Loans shall not require the letter set forth in Section 7.04(a)(i) above or any consent from the Certificateholders or any other party hereto. Upon the transfer of servicing to WMMSC, such Mortgage Loans shall be serviced in accordance with the procedures WMMSC employs in servicing Mortgage Loans serviced by it under this Agreement.

SECTION 7.05

Master Servicer, Seller and Servicers May Own Certificates.

Each of the Master Servicer, each Seller, the Special Servicer and each Servicer in its individual or any other capacity may become the owner or pledgee of Certificates with the same rights as it would have if it were not the Master Servicer, a Seller, the Special Servicer or a Servicer.

If an Event of Default due to the actions or inaction of the Master Servicer or a Servicer described in clauses (a) through (f) of this Section shall occur, then, and in each and every such case, so long as such Event of Default shall not have been remedied, the Trust Administrator shall at the direction of the Trustee or the Holders of Certificates evidencing not less than 25% of the Voting Rights evidenced by the Certificates, by notice in writing to the Master Servicer or such Servicer (with a copy to the Rating Agencies), terminate all of the rights and obligations of the Master Servicer or such Servicer under this Agreement (other than rights to reimbursement for Advances and Servicing Advances previously made, as provided in Section 3.08).

If an Event of Default described in clause (g) shall occur, (i) if the Master Servicer or WMMSC has failed to make any Advance, the Trust Administrator, and (ii) if any Servicer, other than WMMSC, has failed to make any Advance, the Master Servicer, shall prior to the next Distribution Date, immediately make such Advance and terminate the rights and obligations of the Master Servicer or applicable Servicer, as applicable, hereunder and succeed to the rights and obligations of the Master Servicer or such Servicer, as applicable, hereunder pursuant to Section 8.02, including the obligation to make Advances on such succeeding Distribution Date pursuant to the terms hereof. No Event of Default with respect to the Master Servicer or a Servicer shall affect the rights or duties of any other Servicer or constitute an Event of Default as to any other Servicer.

If an Event of Default set forth in clause (h) or (i) shall occur, the Trust Administrator or the Depositor (after consulting with the Trust Administrator), may, or at the direction of Certificateholders evidencing not less than 51% or more of the Voting Rights evidenced by the Certificates, the Trust Administrator shall, by written notice to the Servicer (with a copy to each Rating Agency), terminate all of the rights and obligations of Fairbanks as Servicer under this Agreement. With respect to an Event of Default set forth in clauses (h) or (i) above and upon any termination of Fairbanks as Servicer pursuant to this paragraph, DLJMC, in accordance with Section 7.04(b), shall appoint a successor servicer, irrespective of DLJMC’s ownership of the related servicing rights.

SECTION 8.02

Master Servicer or Trust Administrator to Act; Appointment of Successor.

On and after the time the Master Servicer or a Servicer receives a notice of termination pursuant to Section 8.01 hereof or resigns pursuant to Section 7.04 hereof, subject to the provisions of Section 3.04 hereof, the Trust Administrator (in the case of the Master Servicer or WMMSC), or the Master Servicer (in the case of a Servicer other than WMMSC), shall be the successor in all respects to the Master Servicer or such Servicer, as applicable, in its capacity as servicer under this Agreement and with respect to the transactions set forth or provided for herein and shall be subject to all the responsibilities, duties and liabilities relating thereto placed on the Master Servicer or such Servicer, as applicable, by the terms and provisions hereof, provided that the Trust Administrator or the Master Servicer, as applicable, shall not be deemed to have made any representation or warranty as to any Mortgage Loan made by the Master Servicer or any Servicer, as applicable, and shall not effect any repurchases or substitutions of any Mortgage Loan. As compensation therefor, the Trust Administrator or the Master Servicer, as applicable, shall be entitled to all funds relating to the Mortgage Loans that the Master Servicer or the related Servicer, as applicable, would have been entitled to charge to the related Collection Account if the Master Servicer or such Servicer, as applicable, had continued to act hereunder (except that the terminated or resigning Servicer shall retain the right to be reimbursed for advances (including, without limitation, Advances and Servicing Advances) theretofore made by the Master Servicer or the related Servicer with respect to which it would be entitled to be reimbursed as provided in Section 3.08 if it had not been so terminated or resigned as Master Servicer or Servicer). Notwithstanding the foregoing, if the Trust Administrator, or the Master Servicer, as applicable, has become the successor to the Master Servicer or a Servicer, as applicable, in accordance with this Section 8.02, the Trust Administrator or the Master Servicer, as applicable, 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 mortgage loan servicing institution, the appointment of which does not adversely affect the then current rating of the Certificates, as the successor to the Master Servicer or a Servicer, as applicable, hereunder in the assumption of all or any part of the responsibilities, duties or liabilities of the Master Servicer or such Servicer, as applicable, provided that such successor to the Master Servicer or a Servicer, as applicable, shall not be deemed to have made any representation or warranty as to any Mortgage Loan made by the Master Servicer or the related Servicer, as applicable. Pending appointment of a successor to the Master Servicer or a Servicer, as applicable, hereunder, the Trust Administrator, or the Master Servicer, as applicable, unless such party is prohibited by law from so acting, shall act in such capacity as provided herein. In connection with such appointment and assumption, the Trust Administrator or the Master Servicer, as applicable, may make such arrangements for the compensation of such successor out of payments on Mortgage Loans as it and such successor shall agree; provided, however, that no such compensation shall be in excess of that permitted the Master Servicer or the related Servicer, as applicable, hereunder. The Trust Administrator or the Master Servicer, as applicable, and such successor shall take such action, consistent with this Agreement, as shall be necessary to effectuate any such succession. Neither the Trust Administrator, the Master Servicer nor any other successor servicer shall be deemed to be in default hereunder by reason of any failure to make, or any delay in making, any distribution hereunder or any portion thereof caused by the failure of the Master Servicer or applicable Servicer to deliver, or any delay in delivering, cash, documents or records to it.

A Master Servicer or a Servicer that has been terminated shall, at the request of the Trust Administrator or the Master Servicer, as applicable, but at the expense of such Master Servicer or Servicer, as applicable, deliver to the assuming party all documents and records relating to each Sub-Servicing Agreement and the related Mortgage Loans and an accounting of amounts collected and held by it and otherwise use commercially reasonable efforts to effect the orderly and efficient transfer and assignment of each Sub-Servicing Agreement, but only to the extent of the Mortgage Loans serviced thereunder, to the assuming party. Notwithstanding anything to the contrary contained herein, the termination of the Master Servicer or a Servicer under this Agreement shall not extend to any Sub-Servicer meeting the requirements of Section 3.02(a) and otherwise servicing the related Mortgage Loans in accordance with the servicing provisions of this Agreement.

The Master Servicer and each Servicer shall cooperate with the Trust Administrator and any successor servicer in effecting the termination of the terminated Master Servicer or Servicer’s, as applicable, responsibilities and rights hereunder, including without limitation, the transfer to such successor for administration by it of all cash amounts which shall at the time be credited by the Master Servicer or such Servicer, as applicable, to the applicable Collection Account or thereafter received with respect to the Mortgage Loans.

Neither the Trust Administrator nor any other successor servicer shall be deemed to be in default hereunder by reason of any failure to make, or any delay in making, any distribution hereunder or any portion thereof caused by (a) the failure of the Master Servicer or any Servicer to (i) deliver, or any delay in delivering, cash, documents or records to it, (ii) cooperate as required by this Agreement, or (iii) deliver the Mortgage Loan to the Trust Administrator as required by this Agreement, or (b) restrictions imposed by any regulatory authority having jurisdiction over the Master Servicer or the related Servicer.

Any successor to the Master Servicer or a Servicer as servicer shall during the term of its service as servicer maintain in force the policy or policies that the Master Servicer or such Servicer is required to maintain pursuant to Section 3.09(b) hereof.

Notwithstanding any termination of the Master Servicer hereunder, the Master Servicer shall be entitled to receive prior to transfer of its master servicing obligations hereunder, payment of all accrued and unpaid Master Servicing Fees and reimbursed for all outstanding Advances and Servicing Advances.

Notwithstanding any termination of a Servicer hereunder, such Servicer shall be entitled to receive prior to transfer of its servicing obligations hereunder, payment of all accrued and unpaid Servicing Fees and reimbursed for all outstanding Advances and Servicing Advances.

SECTION 8.03

Notification to Certificateholders.

(a)

Upon any termination or appointment of a successor to the Master Servicer or any Servicer, the Trust Administrator shall give prompt written notice thereof to DLJMC, and the Certificateholders at their respective addresses appearing in the Certificate Register and to the Rating Agencies, or, as applicable, the Master Servicer shall give prompt written notice thereof to the Trust Administrator.

(b)

Within two Business Days after the occurrence of any Event of Default, the Trust Administrator shall transmit by mail to DLJMC and all Certificateholders, and the Rating Agencies notice of each such Event of Default hereunder known to the Trust Administrator, unless such Event of Default shall have been cured or waived.

SECTION 8.04

Waiver of Events of Default.

The Holders representing at least 66% of the Voting Rights of Certificates affected by a default or Event of Default hereunder may waive any default or Event of Default; provided, however, that (a) a default or Event of Default under clause (g) of Section 8.01 may be waived, only by all of the Holders of Certificates affected by such default or Event of Default and (b) no waiver pursuant to this Section 8.04 shall affect the Holders of Certificates in the manner set forth in Section 12.01(b)(i), (ii) or (iii). Upon any such waiver of a default or Event of Default by the Holders representing the requisite percentage of Voting Rights of Certificates affected by such default or Event of Default, such default or Event of Default shall cease to exist and shall be deemed to have been cured and remedied for every purpose hereunder. No such waiver shall extend to any subsequent or other default or Event of Default or impair any right consequent thereon except to the extent expressly so waived.

ARTICLE IX

CONCERNING THE TRUSTEE

SECTION 9.01

Duties of Trustee.

The Trustee, prior to the occurrence of an Event of Default and after the curing or waiver of all Events of Default that may have occurred, undertakes with respect to the Trust Fund to perform such duties and only such duties as are specifically set forth in this Agreement. In case an Event of Default of which a Responsible Officer of the Trustee shall have actual knowledge has occurred and remains uncured, 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 their exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs. Any permissive right of the Trustee set forth in this Agreement shall not be construed as a duty.

The Trustee, upon receipt of all resolutions, certificates, statements, opinions, reports, documents, orders or other instruments furnished to the Trustee that are specifically required to be furnished pursuant to any provision of this Agreement shall examine them to determine whether they conform to the requirements of this Agreement. The Trustee shall have no duty to recompute, recalculate or verify the accuracy of any resolution, certificate, statement, opinion, report, document, order or other instrument so furnished to the Trustee. If any such instrument is found not to conform in any material respect to the requirements of this Agreement, the Trustee shall notify the Certificateholders of such instrument in the event that the Trustee, after so requesting, does not receive a satisfactorily corrected instrument.

No provision of this Agreement shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act or its own misconduct, its negligent failure to perform its obligations in compliance with this Agreement, or any liability which would be imposed by reason of its willful misfeasance or bad faith; provided, however, that:

(a)

prior to the occurrence of an Event of Default of which a Responsible Officer of the Trustee shall have actual knowledge, and after the curing or of all such Events of Default that may have occurred, the duties and obligations of the Trustee shall be determined solely by the express provisions of this Agreement, the Trustee shall not be personally 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 and the 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 the Trustee and conforming to the requirements of this Agreement which it reasonably believed in good faith to be genuine and to have been duly executed by the proper authorities respecting any matters arising hereunder;

(b)

the Trustee shall not be personally liable for an error of judgment made in good faith by a Responsible Officer or Responsible Officers of the Trustee, unless the Trustee was negligent in ascertaining or investigating the pertinent facts;

(c)

the Trustee shall not be personally liable with respect to any action taken, suffered or omitted to be taken by it in good faith in accordance with this Agreement at the direction of the Holders of Certificates evidencing greater than 50% of the Voting Rights allocated to each Class of Certificates relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Agreement;

(d)

no provision of this Agreement shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it; and

(e)

the Trustee shall have no responsibility for any act or omission of the Trust Administrator, it being understood and agreed that the Trustee and Trust Administrator are independent contractors and not agents, partners or joint venturers.

Except with respect to an Event of Default described in clause (a) of Section 8.01, the Trustee shall not be deemed to have knowledge of any Event of Default or event which, with notice or lapse of time, or both, would become an Event of Default, unless a Responsible Officer of the Trustee shall have received written notice thereof from a Servicer, the Depositor, or a Certificateholder, or a Responsible Officer of the Trustee has actual notice thereof, and in the absence of such notice no provision hereof requiring the taking of any action or the assumption of any duties or responsibility by the Trustee following the occurrence of any Event of Default or event which, with notice or lapse of time or both, would become an Event of Default, shall be effective as to the Trustee.

The Trustee shall have no duty hereunder with respect to any complaint, claim, demand, notice or other document it may receive or which may be alleged to have been delivered to or served upon it by the parties as a consequence of the assignment of any Mortgage Loan hereunder; provided, however, that the Trustee shall use its best efforts to remit to the Master Servicer or the related Servicer upon receipt of any such complaint, claim, demand, notice or other document (i) which is delivered to the Corporate Trust Office of the Trustee, (ii) of which a Responsible Officer has actual knowledge, and (iii) which contains information sufficient to permit the Trustee to make a determination that the real property to which such document relates is a Mortgaged Property.

SECTION 9.02

Certain Matters Affecting the Trustee.

(a)

Except as otherwise provided in Section 9.01:

(i) the 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, Servicing Officers or any other certificate, statement, instrument, opinion, report, notice, request, consent, order, appraisal, 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;

(vi) the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any such agent or attorney appointed with due care;

(vii) the Trustee shall not be required to expend its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such liability is not assured to it;

(viii) the Trustee shall not be liable for any loss on any investment of funds pursuant to this Agreement; and

(ix) the right of the Trustee to perform any discretionary act enumerated in this Agreement shall not be construed as a duty, and the Trustee shall not be answerable for other than its negligence or willful misconduct in the performance of such act.

(b)

All rights of action under this Agreement or under any of the Certificates, enforceable by the Trustee, may be enforced by it without the possession of any of the Certificates, or the production thereof at the trial or other proceeding relating thereto, and any such suit, action or proceeding instituted by the Trustee shall be brought in its name for the benefit of all the Holders of such Certificates, subject to the provisions of this Agreement.

SECTION 9.03

Trustee Not Liable for Certificates or Mortgage Loans.

The recitals contained herein shall be taken as the statements of the Depositor or the Master Servicer or a Servicer, as the case may be, and the Trustee assumes no responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of this Agreement, the Certificates or of any Mortgage Loan or related document. The Trustee shall not be accountable for the use or application by the Depositor, any Seller, the Master Servicer or any Servicers of any funds paid to the Depositor or the Master Servicer or any Servicer in respect of the Mortgage Loans or deposited in or withdrawn from the Certificate Account by the Depositor, the Sellers or the Master Servicer or the Servicers. The Trustee shall not be responsible for the legality or validity of this Agreement or the validity, priority, perfection or sufficiency of the security for the Certificates issued or intended to be issued hereunder.

SECTION 9.04

Trustee May Own Certificates.

The Trustee in its individual or any other capacity may become the owner or pledgee of Certificates and may transact business with the other parties hereto and with their Affiliates, with the same rights as it would have if it were not the Trustee.

SECTION 9.05

Trustee’s Fees and Expenses.

The Trustee shall be compensated by the Trust Administrator as separately agreed. The Trustee and any director, officer, employee or agent of the Trustee shall be indemnified by the Depositor and held harmless against any loss, liability or expense (including reasonable attorney’s fees and expenses) (i) incurred in connection with any claim or legal action relating to (a) this Agreement, (b) the Certificates, or (c) the performance of any of the Trustee’s duties hereunder, other than any loss, liability or expense incurred by reason of willful misconduct, bad faith or negligence in the performance of any of the Trustee’s duties hereunder or incurred by reason of any action of the Trustee taken at the direction of the Certificateholders and (ii) resulting from any error in any tax or information return prepared by the Master Servicer or a Servicer. Such indemnity shall survive the termination of this Agreement or the resignation or removal of the Trustee hereunder. Without limiting the foregoing, the Depositor covenants and agrees, except as otherwise agreed upon in writing by the Depositor and the Trustee, and except for any such expense, disbursement or advance as may arise from the Trustee’s negligence, bad faith or willful misconduct, to pay or reimburse the Trustee, for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any of the provisions of this Agreement with respect to: (A) the reasonable compensation and the expenses and disbursements of its counsel not associated with the closing of the issuance of the Certificates, (B) the reasonable compensation, expenses and disbursements of any accountant, engineer or appraiser that is not regularly employed by the Trustee, to the extent that the Trustee must engage such persons to perform acts or services hereunder and (C) printing and engraving expenses in connection with preparing any Definitive Certificates. Except as otherwise provided herein, the Trustee shall not be entitled to payment or reimbursement for any routine ongoing expenses incurred by the Trustee in the ordinary course of its duties as Trustee, Registrar, Tax Matters Person or Paying Agent hereunder or for any other expenses. Anything in this Agreement to the contrary notwithstanding, in no event shall the Trustee be liable for special, indirect or consequential loss or damage of any kind whatsoever (including but not limited to lost profits), even if the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action.

SECTION 9.06

Eligibility Requirements for Trustee.

The Trustee hereunder shall at all times be a corporation or association organized and doing business under the laws of any state or the United States of America, authorized under such laws to exercise corporate trust powers, having ratings on its long term debt obligations at the time of such appointment in at least the third highest rating category by both Xxxxx’x or S&P or such lower ratings as will not cause Xxxxx’x or S&P to lower their then current ratings of the Class A Certificates, having a combined capital and surplus of at least $50,000,000 and subject to supervision or examination by federal or state authority. If such corporation or association publishes reports of condition at least annually, pursuant to law or to the requirements of the aforesaid supervising or examining authority, then for the purposes of this Section 9.06 the combined capital and surplus of such corporation or association shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. In case at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section 9.06, the Trustee shall resign immediately in the manner and with the effect specified in Section 9.07 hereof.

SECTION 9.07

Resignation and Removal of Trustee.

The Trustee may at any time resign and be discharged from the trusts hereby created by (a) giving written notice of resignation to the Depositor, DLJMC, the Trust Administrator, the Master Servicer, the Special Servicer and the Servicers and by mailing notice of resignation by first class mail, postage prepaid, to the Certificateholders at their addresses appearing on the Certificate Register, and to the Rating Agencies, not less than 60 days before the date specified in such notice when, subject to Section 9.08, such resignation is to take effect, and (b) acceptance by a successor trustee in accordance with Section 9.08 meeting the qualifications set forth in Section 9.06.

If at any time the Trustee shall cease to be eligible in accordance with the provisions of Section 9.06 hereof and shall fail to resign after written request thereto by the Depositor, or if at any time the Trustee shall become incapable of acting, or shall be adjudged a bankrupt or insolvent, or a receiver of the Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation or if the Trustee breaches any of its obligations or representations hereunder, then the Depositor may remove the Trustee and appoint a successor trustee by written instrument, in duplicate, one copy of which instrument shall be delivered to the Trustee and one copy to the successor trustee. The Trustee may also be removed at any time by the Holders of Certificates evidencing not less than 50% of the Voting Rights evidenced by the Certificates. Notice of any removal of the Trustee and acceptance of appointment by the successor trustee shall be given to the Rating Agencies by the Depositor.

If no successor trustee shall have been so appointed and have accepted appointment within 30 days after the giving of such notice of resignation or receipt of a notice of removal, the resigning Trustee may, at the Trust Fund’s expense, petition any court of competent jurisdiction for the appointment of a successor trustee.

Any resignation or removal of the Trustee and appointment of a successor trustee pursuant to any of the provisions of this Section 9.07 shall become effective upon acceptance of appointment by the successor trustee as provided in Section 9.08 hereof.

SECTION 9.08

Successor Trustee.

The Trust Administrator, prior to the occurrence of an Event of Default of which a Responsible Officer of the Trust Administrator shall have actual knowledge and after the curing or waiver of all Events of Default that may have occurred, undertakes with respect to the Trust Fund to perform such duties and only such duties as are specifically set forth in this Agreement. In case an Event of Default of which a Responsible Officer of the Trust Administrator shall have actual knowledge has occurred and remains uncured, the Trust Administrator shall exercise such of the rights and powers vested in it by this Agreement, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs. Any permissive right of the Trust Administrator set forth in this Agreement shall not be construed as a duty.

The Trust Administrator, upon receipt of all resolutions, certificates, statements, opinions, reports, documents, orders or other instruments furnished to the Trust Administrator that are specifically required to be furnished pursuant to any provision of this Agreement shall examine them to determine whether they conform to the requirements of this Agreement. The Trust Administrator shall have no duty to recompute, recalculate or verify the accuracy of any resolution, certificate, statement, opinion, report, document, order or other instrument so furnished to the Trust Administrator. If any such instrument is found not to conform in any material respect to the requirements of this Agreement, the Trust Administrator shall notify the Certificateholders of such instrument in the event that the Trust Administrator, after so requesting, does not receive a satisfactorily corrected instrument.

The Trust Administrator shall be responsible, from its fee, for all costs related to S&P’s annual surveillance fee of the Mortgage-Backed Pass-Through Certificates, Series 2003-AR15 transaction.

No provision of this Agreement shall be construed to relieve the Trust Administrator from liability for its own negligent action, its own negligent failure to act or its own misconduct, its negligent failure to perform its obligations in compliance with this Agreement, or any liability which would be imposed by reason of its willful misfeasance or bad faith; provided, however, that:

(a)

prior to the occurrence of an Event of Default of which a Responsible Officer of the Trust Administrator shall have actual knowledge, and after the curing or of all such Events of Default that may have occurred, the duties and obligations of the Trust Administrator shall be determined solely by the express provisions of this Agreement, the Trust Administrator shall not be personally 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 Trust Administrator and the Trust Administrator 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 the Trust Administrator and conforming to the requirements of this Agreement which it reasonably believed in good faith to be genuine and to have been duly executed by the proper authorities respecting any matters arising hereunder;

(b)

the Trust Administrator shall not be personally liable for an error of judgment made in good faith by a Responsible Officer or Responsible Officers of the Trust Administrator, unless the Trust Administrator was negligent in ascertaining or investigating the pertinent facts;

the Trust Administrator shall not be personally liable with respect to any action taken, suffered or omitted to be taken by it in good faith in accordance with this Agreement or at the direction of the Holders of Certificates evidencing greater than 50% of the Voting Rights allocated to each Class of Certificates relating to the time, method and place of conducting any proceeding for any remedy available to the Trust Administrator, or exercising any trust or power conferred upon the Trust Administrator, under this Agreement; and

(d)

no provision of this Agreement shall require the Trust Administrator to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it.

The Trust Administrator shall have no duty (A) to see to any recording, filing or depositing of this Agreement or any agreement referred to herein or any financing statement or continuation statement evidencing a security interest, or to see to the maintenance of any such recording, filing or depositing or to any rerecording, refiling or redepositing of any thereof, (B) to see to any insurance, or (C) to see to the payment or discharge of any tax, assessment or other governmental charge or any lien or encumbrance of any kind owing with respect to, assessed or levied against, any part of the Trust Fund other than from funds available in the Certificate Account.

Except with respect to an Event of Default described in clause (a) of Section 8.01, the Trust Administrator shall not be deemed to have knowledge of any Event of Default or event which, with notice or lapse of time, or both, would become an Event of Default, unless a Responsible Officer of the Trust Administrator shall have received written notice thereof from the Master Servicer or a Servicer, the Depositor, or a Certificateholder, or a Responsible Officer of the Trust Administrator has actual notice thereof, and in the absence of such notice no provision hereof requiring the taking of any action or the assumption of any duties or responsibility by the Trust Administrator following the occurrence of any Event of Default or event which, with notice or lapse of time or both, would become an Event of Default, shall be effective as to the Trust Administrator.

The Trust Administrator shall have no duty hereunder with respect to any complaint, claim, demand, notice or other document it may receive or which may be alleged to have been delivered to or served upon it by the parties as a consequence of the assignment of any Mortgage Loan hereunder; provided, however, that the Trust Administrator shall use its best efforts to remit to the Master Servicer or the related Servicer upon receipt of any such complaint, claim, demand, notice or other document (i) which is delivered to the Corporate Trust Office of the Trust Administrator, (ii) of which a Responsible Officer has actual knowledge, and (iii) which contains information sufficient to permit the Trust Administrator to make a determination that the real property to which such document relates is a Mortgaged Property.

The Trust Administrator shall give notice to the Rating Agencies of election to purchase the Mortgage Loans pursuant to Section 11.01 hereof and of the Optional Termination Date.

(b)

Any purchase of the Mortgage Loans by the Terminating Entity shall be made on an Optional Termination Date by deposit of the applicable purchase price into the Certificate Account, as applicable, before the Distribution Date on which such purchase is effected. Upon receipt by the Trust Administrator of an Officer’s Certificate of the Terminating Entity certifying as to the deposit of such purchase price into the Certificate Account, the Trust Administrator and each co-trust administrator and separate trust administrator, if any, then acting as such under this Agreement, shall, upon request and at the expense of the Terminating Entity execute and deliver all such instruments of transfer or assignment, in each case without recourse, as shall be reasonably requested by the Terminating Entity to vest title in the Terminating Entity in the Mortgage Loans so purchased and shall transfer or deliver to the Terminating Entity the purchased Mortgage Loans. Any distributions on the Mortgage Loans which have been subject to an Optional Termination received by the Trustee subsequent to (or with respect to any period subsequent to) the Optional Termination Date shall be promptly remitted by it to the Terminating Entity.

(c)

Notice of the Distribution Date on which the Master Servicer anticipates that the final distribution shall be made (whether upon Optional Termination or otherwise), shall be given promptly by the Master Servicer to the Trust Administrator and by the Trust Administrator by first class mail to Holders of the affected Certificates. Such notice shall be mailed no earlier than the 15th day and not later than the 10th day preceding the applicable Optional Termination Date or date of final distribution, as the case may be. Such notice shall specify (i) the Distribution Date upon which final distribution on the affected Certificates will be made upon presentation and surrender of such Certificates at the office or agency therein designated, (ii) the amount of such final distribution and (iii) that the Record Date otherwise applicable to such Distribution Date is not applicable, such distribution being made only upon presentation and surrender of such Certificates at the office or agency maintained for such purposes (the address of which shall be set forth in such notice).

(d)

In the event that any Certificateholders shall not surrender Certificates for cancellation within six months after the date specified in the above mentioned written notice, the Trust Administrator shall give a second written notice to the remaining such Certificateholders to surrender their Certificates for cancellation and receive the final distribution with respect thereto. If within six months after the second notice all the Certificates shall not have been surrendered for cancellation, the Trust Administrator may take appropriate steps, or may appoint an agent to 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 subject to the Trust Fund.

(e)

Notwithstanding anything to the contrary herein, the occurrence of an Optional Termination shall be subject to, and shall in no way adversely affect (i) the right of WMMSC to continue servicing and collecting its Servicing Fee for any WMMSC Serviced Mortgage Loan that remains outstanding at the time of such Optional Termination and (ii) the right of WMBFA to continue servicing and collecting its Servicing Fee for any WMBFA Serviced Mortgage Loan that remains outstanding at the time of such Optional Termination.

(i) within 90 days prior to the final Distribution Date set forth in the notice given by Terminating Entity under Section 11.02, the Holder of the Class AR Certificates shall adopt a plan of complete liquidation of Subsidiary REMIC 1 or Subsidiary REMIC 2, as applicable; and

(ii) at or after the time of adoption of any such plan of complete liquidation for Subsidiary REMIC 1 or Subsidiary REMIC 2, as applicable, at or prior to the final Distribution Date, the Trustee shall sell all of the assets of Subsidiary REMIC 1 or Subsidiary REMIC 2, as applicable, to the Depositor for cash; provided, however, that in the event that a calendar quarter ends after the time of adoption of such a plan of complete liquidation but prior to the final Distribution Date, the Trustee shall not sell any of the assets of such REMIC prior to the close of that calendar quarter.

(b)

Upon the exercise of an Optional Termination by Terminating Entity in respect of one Subsidiary REMIC pursuant to paragraph (a) of this Section, followed by the exercise of an Optional Termination in respect of the other Subsidiary REMIC (the “Second Subsidiary REMIC”) pursuant to Section 11.01, the Master REMIC shall be terminated in accordance with the following additional requirements, unless the Trustee and the Trust Administrator have received an Opinion of Counsel to the effect that the failure to comply with the requirements of this Section will not (i) result in the imposition of taxes on a “prohibited transaction” of the REMIC, as described in Section 860F of the Code, or (ii) cause any REMIC created hereunder to fail to qualify as a REMIC at any time that any Certificates are outstanding:

concurrently with the adoption of the plan of complete liquidation of the Second Subsidiary REMIC, as set forth in paragraph (a) of this Section, the Holder of the Class AR Certificates shall adopt a plan of complete liquidation of the Master REMIC; and

at or after the time of adoption of any such plan of complete liquidation for the Master REMIC, at or prior to the final Distribution Date of the Second Subsidiary REMIC to be terminated, the Trustee shall sell all of the assets of the Master REMIC to the Depositor for cash; provided, however, that in the event that a calendar quarter ends after the time of adoption of such a plan of complete liquidation but prior to the final Distribution Date, the Trustee shall not sell any of the assets of the Master REMIC prior to the close of that calendar quarter.

(c)

By its acceptance of a Class AR Certificate, the Holder thereof hereby agrees to adopt such a plan of complete liquidation and to take such other action in connection therewith as may be reasonably required to liquidate and otherwise terminate the Master REMIC, Subsidiary REMIC 1a, Subsidiary REMIC 1b or Subsidiary REMIC 2, as applicable.

SECTION 12.04

Intention of Parties.

(a)

It is the express intent of the Depositor, the Sellers, the Master Servicer, the Servicers, the Special Servicer, the Trust Administrator and the Trustee that (i) the conveyance by DLJMC of the DLJMC Mortgage Loans to the Depositor pursuant to the Assignment and Assumption Agreement and (ii) the conveyance by the Depositor to the Trustee as provided for in Section 2.01 of each of DLJMC’s and the Depositor’s right, title and interest in and to the Mortgage Loans be, and be construed as, an absolute sale and assignment by DLJMC to the Depositor of the DLJMC Mortgage Loans, and by the Depositor to the Trustee of the Mortgage Loans for the benefit of the Certificateholders. Further, it is not intended that any conveyance be deemed to be a pledge of the Mortgage Loans by DLJMC to the Depositor or by the Depositor to the Trustee to secure a debt or other obligation. However, in the event that the Mortgage Loans are held to be property of any Washington Mutual Seller, DLJMC, WMMSC or the Depositor, as applicable, or if for any reason the Assignment and Assumption Agreement or this Agreement is held or deemed to create a security interest in the Mortgage Loans, then it is intended that (i) this Agreement shall also be deemed to be a security agreement within the meaning of Articles 8 and 9 of the New York Uniform Commercial Code and the Uniform Commercial Code of any other applicable jurisdiction; (ii) the conveyances provided for in Section 2.01 shall be deemed to be a grant by the Sellers and the Depositor to the Trustee on behalf of the Certificateholders, to secure payment in full of the Secured Obligations (as defined below), of a security interest in all of the Sellers’ and the Depositor’s right (including the power to convey title thereto), title and interest, whether now owned or hereafter acquired, in and to the Mortgage Loans, including the Mortgage Notes, the Mortgages, any related insurance policies and all other documents in the related Mortgage Files, and all accounts, contract rights, general intangibles, chattel paper, instruments, documents, money, deposit accounts, certificates of deposit, goods, letters of credit, advices of credit and uncertificated securities consisting of, arising from or relating to (A) the Mortgage Loans, including with respect to each Mortgage Loan, the Mortgage Note and related Mortgage, and all other documents in the related Trustee Mortgage Files, and including any Qualified Substitute Mortgage Loans; (B) pool insurance policies, hazard insurance policies and any bankruptcy bond relating to the foregoing, if applicable; (C) the Certificate Account; (D) the Collection Account; (E) all amounts payable after the Cut off Date to the holders of the Mortgage Loans in accordance with the terms thereof; (F) all income, payments, proceeds and products of the conversion, voluntary or involuntary, of the foregoing into cash, instruments, securities or other property, including without limitation all amounts from time to time held or invested in the Certificate Account, whether in the form of cash, instruments, securities or other property; and (G) all cash and non cash proceeds of any of the foregoing; (iii) the possession by the Trustee or any other agent of the Trustee of Mortgage Notes or such other items of property as constitute instruments, money, documents, advices of credit, letters of credit, goods, certificated securities or chattel paper shall be deemed to be a “possession by the secured party”, or possession by a purchaser or a person designated by him or her, for purposes of perfecting the security interest pursuant to the Uniform Commercial Code (including, without limitation, Sections 8-106, 8-301, 9-106, 9-313 and 9 314, thereof); and (iv) notifications to persons holding such property, and acknowledgments, receipts or confirmations from persons holding such property, shall be deemed notifications to, or acknowledgments, receipts or confirmations from, financial intermediaries, securities intermediaries, bailees or agents (as applicable) of the Trustee for the purpose of perfecting such security interest under applicable law. “Secured Obligations” means (i) the rights of each Certificateholder to be paid any amount owed to it under this Agreement and (ii) all other obligations of each Seller and the Depositor under this Agreement and the Assignment and Assumption Agreement.

(b)

Each Seller and the Depositor, and, at the Depositor’s direction, the Master Servicer or the Servicers, the Trustee and the Trust Administrator, shall, to the extent consistent with this Agreement, take such reasonable actions as may be necessary to ensure that, if this Agreement were deemed to create a security interest in the Mortgage Loans and the other property described above, such security interest would be deemed to be a perfected security interest of first priority as applicable. The Depositor shall prepare and file, at the related Servicer’s expense, all filings necessary to maintain the effectiveness of any original filings necessary under the Uniform Commercial Code as in effect in any jurisdiction to perfect the Trustee’s security interest in or lien on the Mortgage Loans, including without limitation (i) continuation statements, and (ii) such other statements as may be occasioned by any transfer of any interest of the Master Servicer or any Servicer or the Depositor in any Mortgage Loan.

SECTION 12.05

In addition to other notices provided under this Agreement, the Trust Administrator shall notify the Rating Agencies in writing: (a) of any substitution of any Mortgage Loan; (b) of any payment or draw on any insurance policy applicable to the Mortgage Loans; (c) of the final payment of any amounts owing to a Class of Certificates; (d) any Event of Default under this Agreement; and (e) in the event any Mortgage Loan is purchased in accordance with this Agreement.

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

No Certificateholder shall have any right by virtue or by availing itself of any provisions of this Agreement to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Agreement, unless such Holder previously shall have given to the Trust Administrator a written notice of an Event of Default and of the continuance thereof, as provided herein, and unless the Holders of Certificates evidencing not less than 25% of the Voting Rights evidenced by the Certificates shall also have made written request upon the Trust Administrator to institute such action, suit or proceeding in its own name as Trust Administrator hereunder and shall have offered to the Trust Administrator such reasonable indemnity as it may require against the costs, expenses, and liabilities to be incurred therein or thereby, and the Trust Administrator, for 60 days after its receipt of such notice, request and offer of indemnity, shall have neglected or refused to institute any such action, suit or proceeding; it being understood and intended, and being expressly covenanted by each Certificateholder with every other Certificateholder and the Trust Administrator, that no one or more Holders of Certificates shall have any right in any manner whatever by virtue or by availing itself or themselves of any provisions of this Agreement to affect, disturb or prejudice the rights of the Holders of any other of the Certificates, or to obtain or seek to obtain priority over or preference to any other such Holder or to enforce any right under this Agreement, except in the manner herein provided and for the common benefit of all Certificateholders. For the protection and enforcement of the provisions of this Section 12.07, each and every Certificateholder and the Trust Administrator shall be entitled to such relief as can be given either at law or in equity.

SECTION 12.08

Certificates Nonassessable and Fully Paid.

It is the intention of the Depositor that Certificateholders shall not be personally liable for obligations of the Trust Fund, that the interests in the Trust Fund represented by the Certificates shall be nonassessable for any reason whatsoever, and that the Certificates, upon due authentication thereof by the Trust Administrator pursuant to this Agreement, are and shall be deemed fully paid.

SECTION 12.09

Protection of Assets.

Except for transactions and activities entered into in connection with the securitization that is the subject of this agreement, the trust created by this agreement is not authorized and has no power to:

(i)

borrow money or issue debt;

(ii)

merge with another entity, reorganize, liquidate or sell assets; or

(iii)

engage in any business or activities.

Each party to this agreement agrees that it will not file an involuntary bankruptcy petition against the Trust Fund or initiate any other form of insolvency proceeding until 366 days after the Certificates have been paid.

(a)

The Master Servicer shall be permitted to provide Fairbanks with advice, reports and recommendations regarding Fairbanks’ collection efforts and the management of specific Fairbanks Mortgage Loans, which advice may be made in writing, in the form of electronic mail or verbally. Such advice shall be based on an evaluation of the information provided pursuant to Section 13.01(a). The advice may include comparable analysis of the performance of the Fairbanks Mortgage Loans with similar mortgage loans serviced by other mortgage loan servicers.

(b)

Each party to the Pooling and Servicing Agreement acknowledges that the Master Servicer’s advice is made in the form of recommendations, and that the Master Servicer does not have the right to direct Fairbanks in performing its duties under this Pooling and Servicing Agreement.
