This TRUST AGREEMENT, dated as of October 1, 2003, by and between Greenwich Capital Acceptance, Inc., as depositor (the “Depositor”), and Deutsche Bank National Trust Company, as trustee (the “Trustee”) recites as follows:

PRELIMINARY STATEMENT

The Depositor has acquired the Underlying Security from the Seller and at the Closing Date is the owner of the Underlying Security and the other property being conveyed by the Depositor to the Trustee hereunder for inclusion in the Trust Fund. On the Closing Date, the Depositor will acquire the Certificates from the Trustee as consideration for the Depositor’s transfer to the Trust Fund of the Underlying Security and certain other property constituting the Trust Fund. The Depositor has duly authorized the execution and delivery of this Agreement to provide for the conveyance to the Trustee of the Underlying Security and the other property constituting the Trust Fund. All representations and warranties made by the Depositor and the Trustee herein with respect to the Underlying Security and the other property constituting the Trust Fund are for the benefit of the Holders from time to time of the Certificates. The Depositor and the Trustee are entering into this Agreement, and the Trustee is accepting the Trust Fund created hereby, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged.

For purposes of the REMIC Provisions, the Underlying Security currently comprises six regular interests in the Underlying Upper Tier REMIC created as part of the Underlying Trust Fund. Specifically, the Underlying Security currently represents ownership of the Underlying Class A2 (which corresponds to the Class A2-1 Component of the Underlying Security), Class A2X, Class M1X, Class M2X, Class M3X, Class B1X, and Class B2X Underlying Upper Tier Regular Interests in the Underlying Upper Tier REMIC.

For purposes of the REMIC Provisions, the Trustee shall elect that the Trust Fund (exclusive of the LIBOR Certificate Cap, the Cap Y Cap, and the assets held in the Reserve Fund, and the Class M1X, Class M2X, Class M3X, Class B1X, and Class B2X Underlying Upper Tier Regular Interests) be treated for federal income tax purposes as comprising two real estate mortgage investment conduits (each a “REMIC” or, in the alternative, the “Lower Tier REMIC” and the “Upper Tier REMIC,” respectively). Each Certificate, other than the Class A-R Certificate and the Class Y Certificate shall represent ownership of a regular interest in the Upper Tier REMIC.

The Class Y Certificate shall represent an ownership interest in the Trust Fund, but not in either REMIC.

Each LIBOR Certificate, in addition to representing a regular interest in the Upper Tier REMIC, represents the right to receive payments in respect of Carryover Shortfalls from the Reserve Fund as provided in Section 3.08.

For purposes of the REMIC Provisions, the owners of the Class X Certificates shall be treated as owning directly the sole beneficial ownership interest in the Class M1X, Class M2X, Class B1X, and Class B2X Underlying Upper Tier Regular Interests and the Reserve Fund. As described below, the Class X Certificate shall also be treated as representing ownership of an interest in the Upper Tier REMIC created under this Agreement.

The Class A-R Certificate represents ownership of the sole class of residual interest in the Upper Tier REMIC and ownership of the Class LT-R Interests which represents the sole class of residual interest in the Lower Tier REMIC.

The Lower Tier REMIC shall issue several classes of uncertificated Lower Tier Interests and each such Lower Tier Interest is hereby designated as a regular interest in the Lower Tier REMIC for purposes of the REMIC Provisions. The Lower Tier REMIC shall also issue the Class LT-R Interest, which is hereby designated as the sole class of residual interest in the Lower Tier REMIC for purposes of the REMIC provisions, ownership of which shall be evidenced by the Class A-R Certificate.

The Upper Tier REMIC will hold as its assets the entire beneficial interest in each Class of uncertificated Lower Tier Interests. The Lower Tier REMIC shall hold as its assets the property of the Trust Fund other than the Lower Tier Interests, the Reserve Fund, the LIBOR Certificate Cap and the Class Y Cap, and the Class M1X, Class M2X, Class B1X, and Class B2X Underlying Upper Tier Regular Interests, which are treated as being owned directly by the beneficial owner of the Class X Certificate.

The Lower Tier REMIC Interests

Class Designation	Interest Rate	Initial Class Principal Amount	Corresponding Class of Certificate
LTA-1	(1)	$ 500,000,000.00	▇-▇
▇▇▇-▇	(1)	$ 85,000,000.00	▇-▇
▇▇▇-▇	(1)	$ 147,439,045.50	A-3
Class LTQ	(1)	$ 732,439,095.50	N/A
Class LT-R(2)	N/A	N/A	Class A-R

_____________

For each Distribution Date (and the related Accrual Period) the interest rate for each of these Lower Tier Interests shall be a rate equal to the difference between (i) the weighted average of the Net Mortgage Rates of the Mortgage Loans held as part of the Underlying Trust Fund as of the first day of the calendar month immediately preceding such Distribution Date, minus (ii) the Trustee Fee Rate.

Class LTR Interest represents the sole class of residual interest in the Lower Tier REMIC. It does not have an interest rate or a Class Principal Amount.

On each Distribution Date, for purposes of the REMIC Provisions, the Trustee shall be deemed to distribute the Interest Distribution Amount among the Lower Tier Interests as follows:

First, concurrently to the Class ▇▇▇-▇, ▇▇▇▇▇ ▇▇▇-▇, and Class LTA-3 Interests, the amount of interest accrued during the related Accrual Period at the rate described in the table above.

Second, to the Class LT-Q Interest, the amount of interest accrued during the related Accrual Period at the rate described above.

If, on any Distribution Date, the Interest Distribution Amount is insufficient to pay all interest that has accrued in the related Accrual Period, any such excess shall be deferred and shall increase the Class Principal Amount of the Lower Tier Interest with respect to which the interest has been deferred. In addition, a portion of the interest accrued on the Class LTQ Interest for any Accrual Period may be deferred and distributed as principal on the other Lower Tier Interests to the extent necessary to cause the Class Principal Amount of each such other Lower Tier Interest to equal 50% of the Class Principal Amount of the Corresponding Class of Certificates.

On each Distribution Date, for purposes of the REMIC Provisions, the Trustee shall be deemed to distribute the Principal Distribution Amount, and any amount of interest deferred on the Class LTQ Interest as described in the immediately preceding sentence, as follows:

First, concurrently to each of the Class ▇▇▇-▇, ▇▇▇▇▇ ▇▇▇-▇, and Class LTA-3 Interests until the Class Principal Amount of each such Lower Tier Interest equals 50% of the Class Principal Amount of the Corresponding Class of Certificates immediately after the Distribution Date;

Second, to the Class LT-Q Interest, the remaining Principal Distribution Amount.

The Upper Tier REMIC Interests

The following table sets forth (or describes) the Class designation, Certificate Interest Rate, initial Class Principal Amount (or initial Class Notional Amount) and minimum denomination for each Class of Certificates constituting interests in the Trust Fund created hereunder, and each such interest, except as provided below and in Section 2.06 hereof, represents a regular interest in the Upper Tier REMIC.

Class Designation	Certificate Interest Rate	Initial Class Principal Amount or Class Notional Amount	Minimum Denominations or Percentage Interest
Class A-1	(1)	$ 1,000,000,000	$ 25,000.00
Class A-2	(2)	$ 170,000,000	$ 25,000.00
Class A-3	(3)	$ 294,878,091	$ 25,000.00
Class X	(4)	(7)	$ 100,000.00
Class A-R	(5)	$ 100	100%
Class Y	(6)	(6)	100%

(1)

The “Certificate Interest Rate” with respect to any Distribution Date (and the related Accrual Period) for the Class A-1 Certificates will be the lesser of (i) One-Month LIBOR plus 0.27% and (ii) the Available Funds Rate; provided, however, if the Underlying Mortgage Loans and related property are not purchased pursuant to Section 10.01 of the Underlying Agreement on the Optional Termination Date (as defined therein), then with respect to each subsequent Distribution Date the per annum rate calculated pursuant to clause (i) above with respect to the Class A-1 Certificates will be LIBOR plus 0.54%.

(2)

The “Certificate Interest Rate” with respect to any Distribution Date (and the related Accrual Period) for the Class A-2 Certificates will be the lesser of (i) One-Month LIBOR plus 0.14% and (ii) the Available Funds Rate; provided, however, if the Underlying Mortgage Loans and related property are not purchased pursuant to Section 10.01 of the Underlying Agreement on the Optional Termination Date (as defined therein), then with respect to each subsequent Distribution Date the per annum rate calculated pursuant to clause (i) above with respect to the Class A-2 Certificates will be LIBOR plus 0.28%.

(3)

The “Certificate Interest Rate” with respect to any Distribution Date (and the related Accrual Period) for the Class A-3 Certificates will equal the lesser of (i) One-Month LIBOR plus 0.32% and (ii) the Available Funds Rate; provided, however, if the Underlying Mortgage Loans and the related property are not purchased pursuant to Section 10.01 of the Underlying Agreement on the Optional Termination Date (as defined therein), then with respect to each subsequent Distribution Date, the per annum rate calculated pursuant to clause (i) above with respect to the Class A-3 Certificates will be LIBOR plus 0.64%.

(4)

The Class X Certificate’s Current Interest entitlement on any Distribution Date will equal the excess, if any, of the Interest Distribution Amount over the sum of the (i) aggregate Current Interest for the LIBOR Certificates and (ii) aggregate LIBOR Certificate Deferred Interest Allocation on such Distribution Date. For purposes of the REMIC Provisions, however, the Class X Certificate shall be deemed to be entitled on each Distribution Date to (i) all amounts distributed on the Underlying Distribution Date with respect to the Class M1X, M2X, B1X,and B2X Underlying Upper Tier Regular Interests, and (ii) all interest accrued during the related Accrual Period on the Lower Tier Interests at a rate equal to the excess of (a) the weighted average of the interest rates on such Lower Tier Interests, over (b) the Adjusted Lower Tier WAC.

(5)

The Class A-R Certificate is a principal-only certificate and, accordingly, shall not bear interest at a stated Certificate Interest Rate.

(6)

The Class Y Certificate shall not bear interest at a stated Certificate Interest Rate and will not be entitled to distributions of principal based on a stated Class Principal Amount or Class Notional Amount, but rather shall solely be entitled to certain payments from the Class Y Cap and the Reserve Fund as set forth in Section 3.08.

(7)

The Class X Certificates are Interest-only Certificates and at any Distribution Date shall bear interest on a Class Notional Amount equal to the aggregate Class Principal Amount of the LIBOR Certificates immediately prior to such Distribution Date. The initial Class Notional Amount of the Class X Certificates is $1,464,878,191.

As of the Cut-off Date, the Underlying Security had an aggregate principal balance of $1,464,878,191.66.

All references herein to “Holders” or “Certificateholders” shall reflect the rights of Certificate Owners as they may indirectly exercise such rights through the Clearing Agency and participating members thereof, except as otherwise specified herein; provided, however, that the Trustee shall be required to recognize as a “Holder” or “Certificateholder” only the Person in whose name a Certificate is registered in the Certificate Register.

LIBOR Certificate Cap: That portion of the Yield Maintenance Agreement, which the Trustee shall account for as a discrete interest rate cap agreement pursuant to Section 3.08 of this Agreement, having terms (other than purchase price therefor), identical to those of the Yield Maintenance Agreement, except that the LIBOR Certificate Cap shall have a notional amount equal at any time to the lesser of (i) the aggregate of the Class Principal Amounts of the LIBOR Certificates and (ii) the notional amount of the Yield Maintenance Agreement at such time.

LIBOR Certificate Deferred Interest Allocation: With respect to each Class of LIBOR Certificates and any Distribution Date, the amount, if any, by which aggregate Current Interest for all Classes of LIBOR Certificates computed without regard to the Available Funds Rate limitation exceeds the sum of (x) the actual amount of aggregate Current Interest for all such Classes and (y) any Basis Risk Payment made on the related Underlying Distribution Date with respect to the Underlying Trust Fund. Any such amount shall be allocated to the Class Principal Amounts of each Class of LIBOR Certificates on the related Distribution Date on the basis of Current Interest otherwise distributable for such Class (without regard to the Available Funds Rate limitation on such Distribution Date).

One-Month LIBOR: With respect to the first Accrual Period, the Initial One-Month LIBOR Rate. With respect to each subsequent Accrual Period, a per annum rate determined on the LIBOR Determination Date for the LIBOR Certificates in the following manner by the Trustee on the basis of the “Interest Settlement Rate” set by the BBA for one-month United States dollar deposits, as such rates appear on the Telerate Page 3750, as of 11:00 a.m. (London time) on such LIBOR Determination Date.

(a)

If on such a LIBOR Determination Date, the BBA’s Interest Settlement Rate does not appear on the Telerate Page 3750 as of 11:00 a.m. (London time), or if the Telerate Page 3750 is not available on such date, the Trustee will obtain such rate from Reuters’ “page LIBOR 01” or Bloomberg’s page “BBAM.” If such rate is not published for such LIBOR Determination Date, One-Month LIBOR for such date will be the most recently published Interest Settlement Rate. In the event that the BBA no longer sets an Interest Settlement Rate, the Trustee shall, after consultation with the Depositor, designate an alternative index that has performed in a manner substantially similar to the BBA’s Interest Settlement Rate. The Trustee will use such designated alternative index as the alternative index only if it receives an Opinion of Counsel (which may be counsel for the Depositor), which opinion shall be an expense reimbursed from the Certificate Account, that the selection of such index will not cause any of the REMICs to lose their classification as REMICs for federal income tax purposes.

(b)

The establishment of One-Month LIBOR by the Trustee and the Trustee’s subsequent calculation of the Certificate Interest Rate applicable to the LIBOR Certificates for the relevant Accrual Period, in the absence of manifest error, will be final and binding.

(ii)

ARTICLE II

CONVEYANCE OF THE UNDERLYING SECURITY;

ORIGINAL ISSUANCE OF CERTIFICATES

Section 2.01.

Conveyance of the Underlying Security. The Depositor, concurrently with the execution and delivery hereof, does hereby transfer, convey, sell and assign to the Trustee, on behalf of the Holders of the Certificates, without recourse, all the right, title and interest of the Depositor in and to the Underlying Security, including all distributions thereon payable after the Underlying Distribution Date in October 2003, and agrees to transfer to the Trustee promptly upon receipt (by wire transfer of immediately available funds), any amounts payable thereon after the Underlying Distribution Date in October 2003 and all proceeds of the foregoing.

The transfer of the Underlying Security and all other assets constituting the Trust Fund is absolute and is intended by the parties hereto as a sale. Except to the extent required under this Agreement to have the Underlying Security reregistered in its own name or a nominee name, the Trustee shall have the beneficial ownership interest in the Book-Entry Underlying Security. The Trustee shall not assign, sell, dispose of or transfer any interest in the Underlying Security or any other asset constituting the Trust Fund or permit the Underlying Security or any other asset constituting the Trust Fund to be subjected to any lien, claim or encumbrance arising by, through or under the Trustee or any Person claiming by, through or under the Trustee. The Depositor agrees to cause all necessary actions to be taken to effect the transfer to the Trustee for the benefit of the Trust of the Depositor’s beneficial ownership in the Underlying Security by book-entry transfer through the Clearing Agency.

It is intended that the conveyance of the Underlying Security by the Depositor to the Trustee as provided in this Section 2.01 be, and be construed as, a sale of the Underlying Security by the Depositor to the Trustee for the benefit of the Certificateholders. It is, further, not intended that such conveyance be deemed a pledge of the Underlying Security by the Depositor to the Trustee to secure a debt or other obligation of the Depositor. However, in the event that the Underlying Security is held to be the property of the Depositor, or if for any reason this Trust Agreement is held or deemed to create a security interest in the Underlying Security, then it is intended that (a) this Trust Agreement shall also be deemed to be a security agreement within the meaning of Articles 8 and 9 of the UCC and the corresponding articles of the Uniform Commercial Code of any other applicable jurisdiction; (b) the conveyance provided for in this Section 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, whether now owned or hereafter acquired, in and to (A) the Underlying Security, (B) all amounts payable to the holder of the Underlying Security after the Underlying Distribution Date in October 2003 in accordance with the terms thereof and (C) all proceeds 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; (c) the registration of the beneficial ownership interest in the Underlying Security with the Clearing Agency in the name of Deutsche Bank National Trust Company as the Securities Intermediary for the account of the Trustee and the possession by the Trustee or its agent of such other items of property as constitute instruments, money, payment intangibles, negotiable documents, goods, deposit accounts, letters of credit, advices of credit, investment property, certificated securities or chattel paper shall be deemed to be “possession by the secured party” or possession by a purchaser or a Person designated by such secured party, for purposes of perfecting the security interest pursuant to the Uniform Commercial Code as in effect in the State of New York and California and the Uniform Commercial Code of any other applicable jurisdiction; 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 purpose of perfecting such security interest under applicable law.

If at any time the Underlying Security is reissued as a Definitive Certificate, the Trustee shall hold or cause the holding of the Underlying Security at its office in the States of New York or Tennessee.

Each of the Certificates is intended to be a “security” governed by Article 8 of the Uniform Commercial Code as in effect in the State of New York and any other applicable jurisdiction, to the extent that any of such laws may be applicable. The Depositor and the Trustee, at the Depositor’s direction and expense, shall, to the extent consistent with this Trust Agreement, take such actions as may be necessary to ensure that, if this Trust Agreement were deemed to create a security interest in the Underlying Security and other assets constituting the Trust Fund described above, 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 the Agreement.

Section 2.02.

Acceptance by Trustee. The Trustee hereby confirms that it has confirmation from Deutsche Bank National Trust Company, as Securities Intermediary for the Trustee, that (i) the Book-Entry Underlying Security has been confirmed by the Clearing Agency to have been delivered to the Securities Intermediary, and held by the Securities Intermediary in book-entry form, as a participant in the Clearing Agency, and (ii) the Securities Intermediary is holding such Book-Entry Underlying Security for the account of the Trustee, as the beneficial owner of the Underlying Security as trustee for the Certificateholders. The Trustee declares that it shall hold the ownership interest in the Underlying Security in trust, upon the terms herein set forth, for the use and benefit of all present and future Certificateholders. The Trustee agrees, for the benefit of Certificateholders, to confirm that the class designation and original principal balance with respect to the Underlying Security conforms to the information set forth on Schedule II hereof within five Business Days after execution and delivery of this Trust Agreement. If in the course of such confirmation the Trustee finds that the information with respect to the Underlying Security does not conform to the related information set forth on Schedule II, the Trustee shall promptly so notify the Depositor. The Depositor shall promptly correct or cure such defect within 15 days from the date it is notified of such omission or defect and, if the Depositor does not correct or cure such omission or defect within such period, the Depositor shall purchase the Underlying Security from the Trustee on or prior to the November 25, 2003 Distribution Date at the Purchase Price of the Underlying Security. The Purchase Price for the purchased Underlying Security shall be deposited in the Certificate Account on such date for distribution to the related Certificateholders on the November 25, 2003 Distribution Date and, upon receipt by the Trustee of such deposit, the Trustee shall cause the Securities Intermediary to hold the repurchased Underlying Security which is a Book-Entry Underlying Security for the account of the Depositor and shall take such other action as shall be necessary to vest in the Depositor or its designee ownership of the Underlying Security released pursuant hereto. It is understood and agreed that the obligation of the Depositor to purchase the Underlying Security shall constitute the sole remedy against the Depositor with respect to a defect or omission available to Certificateholders or the Trustee on behalf of Certificateholders.

Section 2.03.

Representations and Warranties of the Depositor. The Depositor hereby represents and warrants to the Trustee as of the Closing Date as follows:

With respect to the Underlying Security:

(i)

the Depositor is the sole owner of, and has good and marketable title to, the Underlying Security free and clear of any lien, pledge, charge or encumbrance of any kind;

(ii)

(iii)

the Depositor has caused all necessary steps to be taken to effect the transfer of the Underlying Security to the Trustee pursuant to Section 2.01 hereof.

The representations and warranties set forth in this Section 2.03(a) shall survive the transfer and assignment of the Underlying Security. Upon discovery by the Depositor or a Responsible Officer of the Trustee of a breach of any of the foregoing representations and warranties which materially and adversely affects the interests of the Certificateholders in the Underlying Security, the Depositor or the Trustee shall give prompt written notice to the other and to the Certificateholders. On or prior to the Distribution Date next succeeding notice of such breach, the Depositor shall cure such breach in all material respects or, if such breach cannot be cured, the Depositor shall repurchase the Underlying Security on such Distribution Date from the Trustee if the Depositor is so directed by Holders of a Majority in Interest of the Certificates. Any such repurchase of the Underlying Security by the Depositor shall be accomplished at a price (the “Purchase Price”) equal to the principal balance of the Underlying Security on the related Underlying Distribution Date (prior to giving effect to any distributions on such Underlying Distribution Date pursuant to the Underlying Agreement) plus interest thereon at the applicable interest rate for the Underlying Security from the first day of the month of such repurchase up to but not including the date of such repurchase. The payment of the Purchase Price shall be considered a prepayment in full of the Underlying Security and shall be delivered to the Trustee for deposit in the Certificate Account in accordance with the provisions of Section 3.02 hereof. Upon such deposit into the Certificate Account, the repurchased Underlying Security shall be released to the Depositor, and the Trustee shall execute and deliver such instruments of transfer or assignment, without recourse, as shall be reasonably requested and provided by the Depositor to vest in the Depositor, or its designee or assignee, title to the Underlying Security repurchased pursuant hereto. The obligation of the Depositor to cure or repurchase the Underlying Security shall constitute the sole remedy respecting such breach available to Certificateholders or the Trustee on behalf of Certificateholders.

(b)

With respect to the Depositor:

(i)

The Depositor is a corporation duly organized, validly existing and in good standing under the laws of the State of Delaware with full power and authority to execute, deliver and perform this Trust Agreement.

(iii)

Neither the execution nor the delivery of this Trust Agreement nor the issuance, delivery and sale of the Certificates, nor the consummation of any other of the transactions contemplated herein nor the fulfillment of the terms of this Trust Agreement or the Certificates will result in the breach of any term or provision of the charter or bylaws of the Depositor or conflict with, result in a breach, violation or acceleration of or constitute a default under, the terms of any material indenture or other agreement or instrument to which the Depositor is a party or by which it is bound, or any statute, order or regulation applicable to the Depositor of any court, regulatory body, administrative agency or governmental body having jurisdiction over the Depositor.

(iv)

There are no actions or proceedings against, or investigations of, the Depositor pending, or, to the knowledge of the Depositor, threatened, before any court, administrative agency or other tribunal (A) asserting the invalidity of this Trust Agreement or the Certificates, (B) seeking to prevent the issuance of the Certificates or the consummation of any of the transactions contemplated by this Trust Agreement, or (C) which might materially and adversely affect the validity or enforceability of this Trust Agreement or the Certificates.

It is understood and agreed that the representations and warranties set forth in this Section 2.03(b) shall survive delivery of the Trust Fund to the Trustee. Upon discovery by the Depositor or a Responsible Officer of the Trustee of a breach of any of the foregoing representations and warranties which breach materially and adversely affects the interests of the Certificateholders, the party discovering such breach shall give prompt written notice to the other party and to the Rating Agencies and the Trustee shall pursue such remedies in law or equity that are available to it as so directed by the holders of a Majority in Interest of Certificates, provided such Certificateholders shall have offered the Trustee security and indemnity reasonably satisfactory to it against the costs, expenses and liabilities which may be incurred by the Trustee by reason of any such action.

Section 2.04.

Issuance of Certificates.

Section 2.05.

Execution of the Yield Maintenance Agreement and the Transfer and Amendment Agreement. The Depositor hereby instructs the Trustee, solely in its capacity as Trustee hereunder, to execute and deliver, concurrently with the execution and delivery of this Agreement, the Yield Maintenance Agreement and the Transfer and Amendment Agreement in the form provided by the Yield Maintenance Provider. The Trustee shall have no duty or responsibility to enter into any other interest rate cap agreement other than the Yield Maintenance Agreement upon the expiration or termination of the Yield Maintenance Agreement. The Class Y Cap component of the Yield Maintenance Agreement shall not be an asset of the REMIC or the Trust Fund, and the Trustee shall hold the Class Y Cap separate and apart from the assets of the Trust Fund, solely for the benefit of the Class Y Certificateholder. Following termination of the Trust pursuant to a termination under Section 7.01 of this Trust Agreement and payment in full of the Certificates, the Trustee shall assign the Yield Maintenance Agreement to the then holder of record of the Class Y Certificates upon receipt of written request from the Holder thereof or from the Depositor.

The Trustee or its designee shall perform on behalf of each REMIC all reporting and other tax compliance duties that are the responsibility of such REMIC under the Code, the REMIC Provisions, or other compliance guidance issued by the Internal Revenue Service or any state or local taxing authority. Among its other duties, if required by the Code, the REMIC Provisions, or other such guidance, the Trustee shall provide, upon receipt of additional reasonable compensation, (i) to the Treasury or other governmental authority such information as is necessary for the application of any tax relating to the transfer of a Residual Certificate to any disqualified person or organization pursuant to Treasury Regulation 1.860E-2(a)(5) and any person designated in Section 860E(e)(3) of the Code and (ii) such information as is necessary to provide to the Certificateholders such information or reports as are required by the Code or REMIC Provisions.

(e)

The Trustee and the Holders of Certificates shall take all action necessary to elect REMIC status under the REMIC Provisions and shall assist each other as necessary to create such status. Neither the Trustee nor the Holder of any Residual Certificate shall knowingly take any action, cause any REMIC to take any action or fail to take (or fail to cause to be taken) any action that, under the REMIC Provisions, if taken or not taken, as the case may be, would cause an Adverse REMIC Event, unless the Trustee shall 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. In addition, prior to taking any action with respect to any REMIC or the assets therein, or causing any REMIC to take any action, which is not expressly permitted under the terms of this Agreement, any Holder of a Residual Certificate will consult with the Trustee or their respective designees, in writing, with respect to whether such action could cause an Adverse REMIC Event to occur with respect to any REMIC, and no such Person shall take any such action or cause any REMIC to take any such action as to which the Trustee has received an Opinion of Counsel (at the expense of the party seeking to take such action) stating that an Adverse REMIC Event could occur; provided, however, that if no Adverse REMIC Event would occur but such action could result in the imposition of additional taxes on the Residual Certificateholders, no such Person shall take any such action, or cause any REMIC to take any such action without the written consent of the Residual Certificateholders.

(f)

Each Holder of a Residual Certificate shall pay when due any and all taxes imposed on the related REMIC by federal or state governmental authorities. To the extent that such taxes are not paid by a Residual Certificateholder, the Trustee shall pay any remaining REMIC taxes out of current or future amounts otherwise distributable to the Holder of the Residual Certificate in any such REMIC or, if no such amounts are available, out of other amounts held in the Certificate Account, and shall reduce amounts otherwise payable to holders of regular interests in any such REMIC, as the case may be.

(g)

For federal income tax purposes, each REMIC shall report based on a calendar year and on an accrual basis.

(h)

No additional contributions of assets shall be made to any REMIC, except as expressly provided in this Agreement.

(i)

The Trustee shall not enter into any arrangement by which any REMIC will receive a fee or other compensation for services.

(j)

The Trustee shall treat the Class X Certificate as representing (i) a 100% beneficial ownership interest in each of the Class M1X, Class M2X, Class B1X, and Class B2X Underlying Upper Tier Regular Interests, and (ii) a regular interest in the Upper Tier REMIC, as described in the Preliminary Statement. In addition, the Trustee shall treat the Class X Certificateholders as having assumed the obligation to make Basis Risk Payments with respect to the Underlying Trust Fund. Thus, for purposes of the REMIC Provisions, the Trustee shall account for all distributions on the Underlying Security on each Underlying Distribution Date as though they had not been diminished by the amount of any Basis Risk Payment for such date, and shall treat any such Basis Risk Payment as having been made from Current Interest otherwise due with respect to the Class X Certificate before any such amounts are either deposited in the Reserve Fund or distributed in respect of the Class X Certificates.

(k)

The Trustee shall treat the Reserve Fund as an outside reserve fund within the meaning of Treasury Regulation Section 1.860G-2(h) that is beneficially owned by the holders of the Class X and Class Y Certificates. The Class Y Certificateholder will own the portion of the Reserve Fund represented by amounts deposited therein attributable to the Yield Maintenance Agreement. For federal income tax purposes, the Class Y Certificateholder shall be treated as owning an interest rate cap contract represented by the Yield Maintenance Agreement, and as having written interest rate cap contracts in favor of the beneficial owners of the LIBOR Certificates. The Class X Certificateholder shall be treated as the owner of all other amounts held in the Reserve Fund and shall be treated as having written interest rate cap contracts in favor of the LIBOR Certificateholders and has having assumed an interest rate cap contracts with respect to the Underlying Trust Fund represented by the obligation to make Basis Risk Payments to the Underlying Trust Fund. For purposes of the REMIC Provisions, Current Interest paid on any Class of LIBOR Certificates at a rate in excess of the rate at which interest accrues on the Lower Tier Interests shall be treated as a payment made from the Reserve Fund.

(l)

Neither the Depositor nor the Trustee shall sell, dispose of, or substitute for any of the Underlying Security, except in a disposition pursuant to (i) the bankruptcy of the Trust Fund, (ii) the termination of each REMIC pursuant to Article VII of this Agreement or (iii) a repurchase of the Underlying Security pursuant to Section 2.02 or 2.03 of this Agreement, nor acquire any assets for any REMIC, nor sell or dispose of any investments in the Certificate Account for gain, nor accept any contributions to any REMIC after the Closing Date, unless it has received an Opinion of Counsel (at the expense of the party causing such sale, disposition, or substitution) that such disposition, acquisition, substitution, or acceptance will not (a) affect adversely the status of any such REMIC as a REMIC or of the interests therein other than the Residual Certificate as the regular interests therein, (b) affect the distribution of interest or principal on the Certificates, (c) result in the encumbrance of the assets transferred or assigned to the Trust Fund (except pursuant to the provisions of this Agreement) or (d) cause any such REMIC to be subject to any tax including a tax on prohibited transactions or prohibited contributions pursuant to the REMIC Provisions.

ARTICLE III

(b)

All distributions or allocations made with respect to Certificateholders within each Class on each Distribution Date shall be allocated among the outstanding Certificates in such Class equally in proportion to their respective initial Class Principal Amounts or initial Class Notional Amounts (or Percentage Interests).

(iii)

The Trustee will then distribute such amounts (to the extent of the remaining Available Distribution Amount) in the following order of priority:

(i)

from the Interest Distribution Amount, concurrently, on a pro rata basis (based on the amount of Current Interest due for the related Accrual Period), to the Class A-1, Class A-2 and Class A-3 Certificates, Current Interest on such Classes for such Distribution Date;

(ii)

from the Interest Distribution Amount, on a pro rata basis, to the Class A 1, Class A-2 and Class A-3 Certificates, an amount equal to the related aggregate LIBOR Certificate Deferred Interest Allocation made to each such Class on prior Distribution Dates until such amount has been reduced to zero; and

(iii)

from the Interest Distribution Amount, to the Class X Certificates, Current Interest on such Class for such Distribution Date; provided, however, that on each Distribution Date the Current Interest that would otherwise be distributable to the Class X Certificates shall be deposited in the Reserve Fund to the extent of the Required Reserve Fund Deposit and shall not be distributed to the Class X Certificates;

(iv)

concurrently, to the Class A-1, Class A-2 and Class A-3 Certificates, the Principal Distribution Amount for such Distribution Date, on a pro rata basis, as follows:

(a)

(v)

to the Reserve Fund, an amount equal to the Required Reserve Fund Deposit and then from the Reserve Fund, concurrently, on a pro rata basis, based on the respective Carryover Shortfall amount for the Class A-1, Class A-2 and Class A-3 Certificates, the related Carryover Shortfall for such Distribution Date;

(vi)

to the Class X Certificates, an amount equal to the excess, if any, of (i) the amount of Deferred Interest applied against the current interest entitlement of the Underlying Security for the related Underlying Distribution Date over (ii) the aggregate LIBOR Certificate Deferred Interest Allocation for such Distribution Date;

(vii)

to the Trustee, any costs and expenses incurred by and reimbursable to it pursuant to this Agreement, but only to the extent not previously reimbursed to the Trustee from the Interest Distribution Amount for such Distribution Date;

(viii)

to the Depositor, any costs and expenses incurred by and reimbursable to it under Section 6.03; and

(ix)

to the Class A-R Certificate, any remaining Available Distribution Amount for such Distribution Date.

(b)

In the event that on any Underlying Distribution Date, the Trustee shall not have received the cash distribution, if any, required to be made under the Underlying Agreement in respect of the Underlying Security, the Trustee shall effect the related distributions required under paragraph (a) of this Section 3.04 on the Business Day on which the cash distribution so required shall have been received by the Trustee.

(c)

All distributions made with respect to each Class of Certificates on each Distribution Date shall be allocated pro rata among the Certificates of such Class that are Outstanding based upon their respective Percentage Interests. Payments to the Certificateholders of such Class with respect to each Distribution Date will be made to the Certificateholders of record as of the related Record Date (other than as provided in Section 7.01 respecting the final distribution).

(d)

On any Distribution Date, to the extent that the Interest Distribution Amount is reduced as a result of the allocation of Deferred Interest to the Underlying Security, then the Class Principal Amounts of each Class of LIBOR Certificates shall be increased to the extent of the LIBOR Certificate Deferred Interest Allocation allocable to each such Class for such Distribution Date, allocated on a pro rata basis (based on the Current Interest otherwise distributable to such Class for such Distribution Date, determined without regard to the Available Funds Rate limitation.

(e)

The rights of the Certificateholders to receive distributions from the Trust Fund in respect of the Certificates, and all interests of the Certificateholders in such distributions, shall be as set forth in this Trust Agreement. Neither the Holders of any Class of Certificates nor the Depositor nor the Trustee shall in any way be responsible or liable to Holders of any other Class of Certificates in respect of previous amounts properly distributed on the Certificates.

Section 3.05.

the Available Distribution Amount, the Interest Distribution Amount and the Principal Distribution Amount for such Distribution Date;

(ii)

with respect to such Distribution Date, the aggregate amount of principal and/or interest, stated separately, distributed to Holders of each Class of Certificates;

(iii)

the amount of Carryover Shortfall with respect to each Class of LIBOR Certificates;

(iv)

(vi)

any amounts distributed to the holder of the Class Y Certificate from funds received under the Yield Maintenance Agreement pursuant to Section 3.08; and

(vii)

any additional amounts distributed to the Holder of the Residual Certificate on such Distribution Date.

In addition, the Trustee will furnish or otherwise make available to each Certificateholder copies of the monthly remittance report received by the Trustee from the Underlying Trustee for each Underlying Distribution Date as the holder of the Underlying Security on behalf of the Trust Fund. All information provided by the Trustee pursuant to the first and second paragraphs of this Section 3.05 may be provided by the Trustee through its internet website located at “▇▇▇▇▇://▇▇▇.▇▇▇▇▇▇▇▇▇▇▇▇▇▇.▇▇.▇▇▇/▇▇▇▇.”

Within a reasonable period of time after the end of each calendar year, the Trustee will prepare and deliver to each person who at any time during the previous calendar year was a Certificateholder of record a statement containing the information required to satisfy any requirements of the Code, the REMIC Provisions and regulations thereunder as from time to time are in force. For purposes of this Section 3.05, the Trustee’s duties are limited to the extent that adequate information is reasonably available to the Trustee.

Section 3.06.

Reports of the Trustee; Certificate Account. Upon written request of a Certificateholder and at the expense of such Certificateholder, the Trustee shall make available to Certificateholders within 15 days after the date of receipt of such request a statement setting forth the status of the Certificate Account as of the close of business on the last day of the calendar month immediately preceding such request, and showing, for the period covered by such statement, the aggregate of deposits into and withdrawals from the Certificate Account.

Section 3.07.

Access to Certain Documentation and Information. In addition to the information provided under Section 3.05, the Trustee shall provide the related Certificateholders with access to a copy of any additional report or notifications received by it as holder of the Underlying Security under the Underlying Agreement. The Trustee shall also provide the Depositor with access to any such additional report or notification and to all written reports, documents and records required to be maintained by the Trustee in respect of its duties hereunder. Such access shall be afforded without charge, but only upon reasonable request evidenced by prior written notice received by the Trustee two Business Days prior to the date of such proposed access and during normal business hours of the Trustee.

Section 3.08.

The Reserve Fund and the Yield Maintenance Agreement.

(a)

On the Closing Date, the Trustee shall establish and maintain in the Trustee’s name, in trust for the benefit of the holders of the LIBOR Certificates, the Class X Certificates and the Class Y Certificates, a Reserve Fund, into which the Depositor shall make an initial deposit of $3,000. In addition, the Trustee shall hold the LIBOR Certificate Cap as an asset of the Reserve Fund. The 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 of the Trustee held pursuant to this Agreement. The Reserve Fund shall not be an asset of any REMIC established hereof.

(b)

The Trustee shall account for the Yield Maintenance Agreement as though it were composed of two component interest rate cap agreements the LIBOR Certificate Cap and the Class Y Cap. The Class Y Cap shall not be an asset of the REMIC or the Trust Fund or the Reserve Fund. On each Distribution Date, the Trustee shall immediately distribute to the Class Y Certificateholder any payments made by the Yield Maintenance Provider to the Trust Fund for such Distribution Date with respect to the Class Y Cap and the Trustee shall not treat such amounts as amounts on deposit in the Reserve Fund for the purposes of determining the Required Reserve Fund Deposit for such Distribution Date. On each Distribution Date, in addition to any Required Reserve Fund Deposit for such date, the Trustee will deposit into the Reserve Fund any amounts the Trustee shall have received from the Yield Maintenance Provider attributable to the LIBOR Certificate Cap.

(c)

On each Distribution Date, for which there exists Carryover Shortfalls with respect to the LIBOR Certificates, the Trustee shall withdraw from the Reserve Fund the amount of the aggregate Carryover Shortfall for distribution on such Distribution Date pursuant to Section 3.04(a)(v). Such amount shall be deemed paid first, from funds received under the LIBOR Certificate Cap and, second, to the extent such funds are insufficient to pay the full amount of the Carryover Shortfall, from Current Interest that would otherwise be distributable to the Class X Certificateholder. If immediately after such application the amount on deposit in the Reserve Fund exceeds the Required Reserve Fund Deposit, the Trustee shall distribute that portion of any excess attributable to the LIBOR Certificate Cap to the Class Y Certificateholder and any remaining amount of excess to the Class X Certificateholder.

(d)

Funds on deposit in the Reserve Fund shall be invested in Permitted Investments. Any earnings on amounts in the Reserve Fund shall be for the benefit of the Class X and Class Y Certificateholders to be distributed pro rata in accordance with the amount of Class X Current Interest and LIBOR Certificate Cap payments used to fund Carryover Shortfalls. The Class X and Class Y Certificates shall evidence ownership of the Reserve Fund for federal income tax purposes. The Class X Certificateholders shall instruct the Trustee, in writing (which written instruction may be standing instruction), as to investment of amounts on deposit in the Reserve Fund. The Class X Certificateholders shall be liable for any losses incurred on such investments. In the absence of written instructions from the Class X Certificateholders as to investment of funds on deposit in the Reserve Fund, such funds shall be invested in the ▇▇▇▇▇ Fargo Prime Money Market Fund. For all Federal income tax purposes, amounts transferred by the Upper-Tier REMIC to the Reserve Fund shall be treated as amounts distributed by the Upper-Tier REMIC to the Class X Certificateholders.

(e)

Upon termination of the Trust Fund any amounts remaining in the Reserve Fund attributable to the LIBOR Certificate Cap shall be distributed to the Class Y Certificateholder and any other remaining amounts shall be distributed to the Class X Certificateholders.

(f)

The Trustee or its Affiliates are permitted to receive additional compensation that would be deemed to be in the Trustee’s economic self-interest for (i) serving as investment advisor, administrator, shareholder, servicing agent, custodian or sub-custodian with respect to certain of the Permitted Investments, (ii) using Affiliates to effect transactions in certain Permitted Investments and (iii) effecting transactions in certain Permitted Investments.

ARTICLE IV

THE CERTIFICATES

Section 4.01.

The Certificates. The Certificates shall be substantially in the form annexed hereto as Exhibit C. Each of the Certificates shall, on original issue, be executed by the Trustee and authenticated and delivered by the Certificate Registrar upon the written order of the Depositor concurrently with the sale and assignment to the Trustee of the Trust Fund. Each Class of the Book-Entry Certificates shall be initially evidenced by one or more Certificates representing a Percentage Interest with a minimum denomination or Percentage Interest specified for the related Class in the Preliminary Statement hereto, except that the Class A-3 Certificates may be in a different denomination so that the sum of the denominations of all outstanding Certificates of such Class shall equal the Class Certificate Principal Balance of such Class on the Closing Date. The Class A-R and Class Y Certificates are issuable only in a Percentage Interest of 100%.

The Certificates shall be executed on behalf of the Trust by manual or facsimile signature on behalf of the Trustee 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 Trustee shall be binding, 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. Each Certificate shall, on original issue, be authenticated by the Trustee upon the order of the Depositor. No Certificate shall be entitled to any benefit under this Agreement or be valid for any purpose, unless such Certificate shall have been manually authenticated by the Trustee substantially in the form provided for herein, and such 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. At any time and from time to time after the execution and delivery of this Agreement, the Depositor may deliver Certificates to the Trustee for execution and authentication and the Certificate Registrar shall authenticate and deliver such Certificates as provided in this Agreement and not otherwise. Subject to Section 4.02(c), the LIBOR Certificates shall be Book-Entry Certificates. Each of the Residual Certificate, the Class X Certificate and the Class Y Certificate shall be Definitive Certificates.

The Class X Certificates shall be offered and sold in reliance on the exemption from registration under Rule 144A of the Securities Act and shall be issued initially in the form of one or more permanent global Certificates in definitive, fully registered form with the applicable legends set forth in Exhibit C (each, a “Restricted Global Security”), which shall be deposited on behalf of the subscribers for such Certificates represented thereby with the Trustee, as custodian for The Depository Trust Company (“DTC”), the initial Clearing Agency, and registered in the name of a nominee of DTC, duly executed by the Trustee and authenticated by the Certificate Registrar as hereinafter provided. The aggregate principal amounts of the Restricted Global Securities may from time to time be increased or decreased by adjustments made on the records of the Trustee and DTC or its nominee, as the case may be, as hereinafter provided. Notwithstanding the foregoing, the Class X Certificates may be subsequently offered as registered certificates pursuant to an amendment to the Registration Statement without any required amendment to this Agreement or the prior consent of the Certificateholders or the Rating Agencies.

Section 4.02.

Registration of Transfer and Exchange of Certificates. (a) The Certificate Registrar shall cause to be kept a Certificate Register in which, subject to such reasonable regulations as it may prescribe, the Certificate Registrar shall provide for the registration of Certificates and of transfers and exchanges of Certificates as herein provided. The Trustee is hereby appointed, and the Trustee hereby accepts its appointment as, initial Certificate Registrar for the purpose of registering Certificates and transfers and exchanges of Certificates as herein provided.

Upon surrender for registration of transfer of any Certificate at the Corporate Trust Office of the Certificate Registrar maintained for such purpose pursuant to the foregoing paragraph, the Trustee on behalf of the Trust shall execute, and the Certificate Registrar shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates of the same aggregate Percentage Interest.

At the option of the Certificateholders, Certificates may be exchanged for other Certificates in authorized denominations and the same aggregate Percentage Interests, upon surrender of the Certificates to be exchanged at any such office or agency. Whenever any Certificates are so surrendered for exchange, the Trustee shall execute on behalf of the Trust, and the Certificate Registrar shall 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 (if so required by the Certificate Registrar) be duly endorsed by, or be accompanied by a written instrument of transfer satisfactory to the Certificate Registrar duly executed by, the Holder thereof or his attorney duly authorized in writing.

(b)

Except as provided in paragraph (c) or (d) below, the Book-Entry Certificates shall at all times remain registered in the name of the DTC, as the initial Clearing Agency, or its nominee and at all times: (i) registration of such Certificates may not be transferred by the Trustee or the Certificate Registrar except to another Clearing Agency; (ii) the Clearing Agency shall maintain book-entry records with respect to the Holders and with respect to ownership and transfers of such Certificates; (iii) ownership and transfers of registration of such Certificates on the books of the Clearing Agency shall be governed by applicable rules established by the Clearing Agency; (iv) the Clearing Agency may collect its usual and customary fees, charges and expenses from its Clearing Agency Participants; (v) the Certificate Registrar and the Trustee shall for all purposes deal with the Clearing Agency as representative of the Holders of the Certificates for purposes of exercising the rights of Holders under this Agreement, and requests and directions for and votes of such representative shall not be deemed to be inconsistent if they are made with respect to different Holders; (vi) the Trustee and the Certificate Registrar may rely and shall be fully protected in relying upon information furnished by the Clearing Agency with respect to its Clearing Agency Participants and furnished by the Clearing Agency Participants with respect to indirect participating firms and Persons shown on the books of such indirect participating firms as direct or indirect Holders; and (vii) the direct participants of the Clearing Agency shall have no rights under this Agreement under or with respect to any of the Certificates held on their behalf by the Clearing Agency, and the Clearing Agency may be treated by the Trustee, the Certificate Registrar and their respective agents, employees, officers and directors as the absolute owner of the Certificates for all purposes whatsoever.

All transfers by Holders of Book-Entry Certificates shall be made in accordance with the procedures established by the Clearing Agency Participant or brokerage firm representing such Holders. Each Clearing Agency Participant shall only transfer Book Entry Certificates of Holders that it represents or of brokerage firms for which it acts as agent in accordance with the Clearing Agency’s normal procedures. The parties hereto are hereby authorized to execute one or more Letter of Representations with the Clearing Agency or take such other action as may be necessary or desirable to register a Book-Entry Certificate to the Clearing Agency. In the event of any conflict between the terms of any such Letter of Representation and this Agreement, the terms of this Agreement shall control.

(c)

If (i)(x) the Clearing Agency or the Depositor advises the Certificate Registrar in writing that the Clearing Agency is no longer willing or able to discharge properly its responsibilities as Clearing Agency and (y) the Certificate Registrar or the Depositor is unable to locate a qualified successor or (ii) the Depositor, at its sole option, with the consent of the Certificate Registrar, elects to terminate the book-entry system through the Clearing Agency, upon surrender to the Certificate Registrar of the Book-Entry Certificates by the Clearing Agency, accompanied by registration instructions from the Clearing Agency for registration, the Trustee shall, at the Depositor’s expense, execute on behalf of the Trust and authenticate the Definitive Certificates. Neither the Depositor nor the Certificate Registrar 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, the Trustee, the Certificate Registrar and the Depositor shall recognize the Holders of the Definitive Certificates as Certificateholders hereunder.

(d)

No transfer, sale, pledge or other disposition of any Class X Certificate shall be made unless such disposition is exempt from the registration requirements of the Securities Act, and any applicable state securities laws or is made in accordance with the Securities Act and laws. Any Class X Certificates sold to an “accredited investor” under Rule 501(a)(1), (2), (3) or (7) under the Securities Act shall be issued only in the form of one or more Definitive Certificates and the records of the Certificate Registrar and DTC or its nominee shall be adjusted to reflect the transfer of such Definitive Certificates. In the event of any transfer of any Class X Certificate in the form of a Definitive Certificate, the transferee shall certify (A) such transfer is made to a Qualified Institutional Buyer in reliance upon Rule 144A (as evidenced by an investment letter delivered to the Certificate Registrar, in substantially the form attached hereto as Exhibit E-2) under the Securities Act, or (B) such transfer is made to an “accredited investor” under Rule 501(c)(1), (2), (3) or (7) under the Securities Act (as evidenced by an investment letter delivered to the Certificate Registrar, in substantially the form attached hereto as Exhibit E-1, and, if so required by the Certificate Registrar and the Depositor, a written Opinion of Counsel (which may be in-house counsel) acceptable to and in form and substance reasonably satisfactory to the Certificate Registrar and the Depositor, delivered to the Certificate Registrar and the Depositor stating that such transfer may be made pursuant to an exemption, including a description of the applicable exemption and the basis therefor, from the Securities Act or is being made pursuant to the Securities Act, which Opinion of Counsel shall not be an expense of the Trust, the Trustee, the Certificate Registrar or the Depositor). Each Holder of a Class X Certificate desiring to effect such transfer shall, and does hereby agree to, indemnify the Trustee, the Certificate Registrar and the Depositor 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. The Class Y Certificate shall only be issued as a Definitive Certificate and shall only be transferred pursuant to clauses (i)(A) and (ii) above.

In the case of a Class X Certificate that is a Book-Entry Certificate, for purposes of the preceding paragraph, the representations set forth in the investment letter in clause (i) shall be deemed to have been made to the Certificate Registrar by the transferee’s acceptance of such Class X Certificate that is also a Book-Entry Certificate (or the acceptance by a Certificate Holder of the beneficial interest in such Certificate).

No transfer of an ERISA-Restricted Certificate in the form of a Definitive Certificate shall be made unless the Certificate Registrar shall have received either (i) a representation from the transferee of such Certificate, acceptable to and in form and substance satisfactory to the Certificate Registrar and the Depositor (such requirement is satisfied only by the Certificate Registrar’s receipt of a representation letter from the transferee substantially in the form of Exhibit D hereto), to the effect that such transferee is not an employee benefit plan subject to Section 406 of ERISA or a plan or arrangement subject to Section 4975 of the Code, nor a person acting on behalf of any such plan or arrangement nor using the assets of any such plan or arrangement to effect such transfer or (ii) if a Class Y Certificate, such Certificate has been the subject of an ERISA-Qualifying Underwriting, (iii) if the Class Y or the Class A R Certificate, if such Certificate has been the subject of an ERISA-Qualifying Underwriting, and the purchaser is an insurance company, 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 (iv) an Opinion of Counsel satisfactory to the Certificate Registrar, which Opinion of Counsel shall not be an expense of the Trustee, the Certificate Registrar, the Depositor or the Trust, addressed to the Certificate Registrar, to the effect that the purchase and holding of such ERISA-Restricted Certificate in the form of a Definitive Certificate will not result in a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code and will not subject the Trustee, the Certificate Registrar or the Depositor to any obligation in addition to those expressly undertaken in this Agreement or to any liability. Notwithstanding anything else to the contrary herein, any purported transfer of an ERISA-Restricted Certificate in the form of a Definitive Certificate to an employee benefit plan subject to ERISA or Section 4975 of the Code without the delivery to the Certificate Registrar of an Opinion of Counsel satisfactory to the Certificate Registrar as described above shall be void and of no effect.

In the case of an ERISA-Restricted Certificate that is a Book-Entry Certificate, for purposes of clauses (i) or (ii) of the first sentence of the preceding paragraph, such representations shall be deemed to have been made to the Certificate Registrar by the transferee’s acceptance of such ERISA-Restricted Certificate that is also a Book-Entry Certificate (or the acceptance by a Certificate Holder of the beneficial interest in such Certificate).

To the extent permitted under applicable law (including, but not limited to, ERISA), none of the Trustee, the Certificate Registrar or the Depositor shall have any liability to any Person for any registration of transfer of any ERISA-Restricted Certificate that is in fact not permitted by this Section 4.02(d) or for the Trustee (or any paying agent on its behalf) making any payments due on such Certificate to the Holder thereof or taking any other action with respect to such Holder under the provisions of this Agreement so long as the transfer was registered by the Certificate Registrar in accordance with the foregoing requirements. In addition, none of the Trustee, the Certificate Registrar or the Depositor shall be required to monitor, determine or inquire as to compliance with the transfer restrictions with respect to any ERISA-Restricted Certificate in the form of a Book-Entry Certificate, and none of the Trustee, the Certificate Registrar or the Depositor shall have any liability for transfers of Book-Entry Certificates or any interests therein made in violation of the restrictions on transfer described in the Prospectus and this Agreement.

(e)

Each Person who has or who acquires any Ownership Interest in the Class A-R 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 appointed the Depositor or its designee as its attorney-in-fact to negotiate the terms of any mandatory sale under clause (v) below and to execute all instruments of transfer and to do all other things necessary in connection with any such sale, and the rights of each Person acquiring any Ownership Interest in a Residual Certificate are expressly subject to the following provisions:

(i)

Each Person holding or acquiring any Ownership Interest in a Class A-R Certificate shall be a Permitted Transferee who acquires such Ownership Interest in a Class A-R Certificate for its own account and not in the capacity as trustee, nominee or agent for another Person and shall promptly notify the Certificate Registrar and the Trustee of any change or impending change in its status as such a Permitted Transferee.

(ii)

No Ownership Interest in the Class A-R Certificate may be registered on the Closing Date and no Ownership Interest in a Residual Certificate may thereafter be transferred, and the Certificate Registrar shall not register the Transfer of a Residual Certificate unless, in addition to the certificates required to be delivered under subsection (d) above, the Trustee and the Certificate Registrar shall have been furnished with an affidavit (“Transfer Affidavit”) of the initial owner of the Class A-R Certificate or proposed transferee of a Residual Certificate in the form attached hereto as Exhibit G.

(iii)

In connection with any proposed transfer of any Ownership Interest in a Residual Certificate, the Trustee and the Certificate Registrar shall as a condition to registration of the transfer, require delivery to them of a Transferor Certificate in the form of Exhibit G hereto from the proposed transferor to the effect that the transferor (a) has no knowledge the proposed Transferee is not a Permitted Transferee acquiring an Ownership Interest in such Class A-R Certificate for its own account and not in a capacity as trustee, nominee, or agent for another Person, and (b) has not undertaken the proposed transfer in whole or in part to impede the assessment or collection of tax.

(iv)

Any attempted or purported Transfer of any Ownership Interest in a Residual Certificate in violation of the provisions of this Section shall be absolutely null and void and shall vest no rights in the purported transferee. If any purported transferee shall, in violation of the provisions of this Section, become a Holder of such Residual Certificate, then the prior Holder of such Residual Certificate that is a Permitted Transferee shall, upon discovery that the registration of Transfer of such Residual Certificate was not in fact permitted by this Section, be restored to all rights as Holder thereof retroactive to the date of registration of transfer of such Residual Certificate. None of the Trustee, the Certificate Registrar or the Depositor shall have any liability to any Person for any registration of Transfer of a Residual Certificate that is in fact not permitted by this Section or for the Trustee (or any paying agent on its behalf) making any distributions due on a Residual Certificate to the Holder thereof or taking any other action with respect to such Holder under the provisions of this Agreement so long as the Trustee and the Certificate Registrar received the documents specified in clause (iii). The Certificate Registrar shall be entitled to recover from any Holder of such Residual Certificate that was in fact not a Permitted Transferee at the time such distributions were made all distributions made on such Residual Certificate. Any such distributions so recovered by the Certificate Registrar shall be distributed and delivered by the Certificate Registrar to the last Holder of such Residual Certificate that is a Permitted Transferee.

(v)

If any Person other than a Permitted Transferee acquires any Ownership Interest in a Residual Certificate in violation of the restrictions in this Section, then the Trustee shall have the right but not the obligation, without notice to the Holder of such Residual Certificate or any other Person having an Ownership Interest therein, to notify the Depositor to arrange for the sale of such Residual Certificate. The proceeds of such sale, net of commissions (which may include commissions payable to the Depositor or its affiliates in connection with such sale), expenses and taxes due, if any, will be remitted by the Certificate Registrar to the previous Holder of such Residual Certificate that is a Permitted Transferee, except that in the event that the Certificate Registrar determines that the Holder of such Residual Certificate may be liable for any amount due under this Section or any other provisions of this Agreement, the Certificate Registrar may withhold a corresponding amount from such remittance as security for such claim. The terms and conditions of any sale under this clause (v) shall be determined in the sole discretion of the Trustee and the Certificate Registrar and they shall not be liable to any Person having an Ownership Interest in such Residual Certificate as a result of its exercise of such discretion.

(vi)

If any Person other than a Permitted Transferee acquires any Ownership Interest in a Residual Certificate in violation of the restrictions in this Section, then the Trustee upon receipt of reasonable compensation will provide to the Internal Revenue Service, and to the persons specified in Sections 860E(e)(3) and (6) of the Code, information needed to compute the tax imposed under Section 860E(e)(5) of the Code on transfers of residual interests to disqualified organizations.

The foregoing provisions of this Section shall cease to apply to transfers occurring on or after the date on which there shall have been delivered to the Certificate Registrar and the Servicer, in form and substance satisfactory to the Certificate Registrar, (i) written notification from the Rating Agencies that the removal of the restrictions on Transfer set forth in this Section will not cause the applicable Rating Agency to downgrade its ratings of the Certificates and (ii) an Opinion of Counsel to the effect that such removal will not cause the REMIC created hereunder to fail to qualify as a REMIC.

(f)

No service charge shall be made for any registration of transfer or exchange of Certificates of any Class, but the Certificate Registrar may require 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.

All Certificates surrendered for registration of transfer or exchange shall be cancelled by the Certificate Registrar and disposed of pursuant to its standard procedures.

Section 4.03.

Mutilated, Destroyed, Lost or Stolen Certificates. If (i) any mutilated Certificate is surrendered to the Trustee or the Certificate Registrar or the Trustee or the Certificate Registrar receives evidence to its satisfaction of the destruction, loss or theft of any Certificate and (ii) there is delivered to the Trustee, the Depositor and the Certificate Registrar 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, the Depositor or the Certificate Registrar that such Certificate has been acquired by a bona fide purchaser, the Trustee shall execute on behalf of the Trust Fund and the Certificate Registrar shall 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 Percentage Interest. Upon the issuance of any new Certificate under this Section, the Trustee, the Depositor or the Certificate Registrar may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee, the Depositor and the Certificate Registrar) in connection therewith. Any duplicate Certificate issued pursuant to this Section, 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 4.04.

Persons Deemed Owners. The Depositor, the Trustee, the Certificate Registrar and any agent of the Depositor, the Trustee or the Certificate Registrar may treat the Person, including a Clearing Agency, in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions pursuant to Section 3.04 hereof and for all other purposes whatsoever, and none of the Trust Fund, the Depositor, the Trustee, the Certificate Registrar or any agent of any of them shall be affected by notice to the contrary.

Section 4.05.

Maintenance of Office or Agency. The Trustee will maintain at its expense in New York City, State of New York, an office or agency where Certificates may be surrendered for registration of transfer or exchange and presented for final distribution and where notices to or upon the related Trust Fund in respect of the Certificates and this Trust Agreement may be delivered. Such office or agency shall initially be maintained at DTC Transfer Agent Services, ▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇. The Trustee will give prompt written notice to the Certificateholders and the Depositor of any change in the location of any such office or agency.

(ii)

The Trustee shall not be individually or as Trustee liable for an error of judgment made in good faith by a Responsible Officer or Responsible Officers of the Trustee, unless it shall be proved that the Trustee was negligent or acted in bad faith or with willful misfeasance in performing its duties in accordance with the terms of this Trust Agreement; and

(iii)

The Trustee shall not be liable, individually or as Trustee, with respect to any action taken, suffered or omitted to be taken by it in good faith in accordance with the direction of the Holders of Certificates of any Class of Certificates evidencing Percentage Interests in such Class aggregating not less than 25% 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 Trust Agreement.

Section 5.02.

Certain Matters Affecting the Trustee. (a) Except as otherwise provided in Section5.01 hereof:

(vii)

The Trustee shall not be required to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties or in the exercise of any of its rights or powers hereunder if it shall have reasonable grounds for believing that repayment of such funds or indemnity reasonably satisfactory to it against such liability is not assured to it;

(viii)

The Trustee shall be under no obligation to exercise any of the trusts or powers vested in it by this Trust Agreement or to make any investigation of matters arising hereunder or to institute, conduct or defend any litigation hereunder or in relation hereto at the request, order or direction of any of the Certificateholders, pursuant to the provisions of this Trust Agreement, unless such Certificateholders shall have offered to the Trustee security or indemnity reasonably satisfactory to it against the costs, expenses and liabilities which may be incurred therein or thereby;

(ix)

Whenever in the administration of this Trust Agreement the Trustee shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Trustee (unless other evidence be herein specifically prescribed) may, in the absence of bad faith on its part, conclusively rely upon an Officers’ Certificate; and

(x)

The Trustee shall not be deemed to have notice of any breach by the Depositor of any representation, warranty or covenant or any default or event of default unless a Responsible Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is in fact such a default or breach is received by a Responsible Officer of the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Certificates and this Trust Agreement.

(b)

All rights of action under this Trust 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 the Certificates, subject to the provisions of this Trust Agreement.

Section 5.03.

Trustee Not Liable for Certificates. The recitals contained herein and in the Certificates, other than the signature of the Trustee on the Certificates, shall be taken as the statements of the Depositor and the Trustee assumes no responsibility for their correctness. The Trustee makes no representations or warranties as to the validity or sufficiency of this Trust Agreement or of the Certificates or of the Underlying Security or related documents, other than the signature of the Trustee on the Certificates. The Trustee shall not be accountable for the use or application by the Depositor of any of the Certificates or of the proceeds of such Certificates, or for the use or application of any funds paid to the Depositor in respect of the Underlying Security.

Section 5.04.

The Trustee and any director, officer, employee, or agent of the Trustee shall be indemnified and held harmless by the Trust Fund against any and all losses, liabilities, damages, claims or expenses arising out of or in connection with the acceptance or administration of the trust or trusts hereunder (including, without limitation, any losses, liabilities, damages, claims or expenses incurred in defending itself against any claim or liability in connection with the exercise or performance of any powers or duties hereunder), other than those resulting from the negligence or bad faith in the performance of any of the Trustee’s duties hereunder or by reason of reckless disregard of the Trustee’s obligations and duties hereunder; provided, however, that costs and expenses owed to the Trustee by reason of this Section 5.05 shall not include expenses payable or paid by the Underlying Trust Fund on the Underlying Security to the Trustee in its capacity as Underlying Trustee of the Underlying Trust Fund. Such indemnification shall survive the termination of this Trust Agreement and the Trust Fund created hereby or the resignation or removal of the Trustee pursuant to the terms hereof.

Section 5.06.

Eligibility Requirements for the Trustee. The Trustee hereunder shall at all times (i) be a corporation or a national banking association organized and doing business under the laws of any state or the United States of America or the District of Columbia, authorized under such laws to exercise corporate trust powers, having a combined capital and surplus of at least $50,000,000 and subject to supervision or examination by federal or state authority and (ii) satisfy the requirements of paragraph (a) (4) of Rule 3a-7. 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 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, the Trustee shall resign immediately in the manner and with the effect specified in Section 5.07 hereof. The corporation or national banking association serving as Trustee may have normal banking and trust relationships with the Depositor and its affiliates; provided, however, that such corporation or association cannot be an affiliate of the Depositor.

Section 5.07.

Resignation and Removal of the Trustee. Subject to the requirements set forth in this Article V, the Trustee may at any time resign and be discharged from the trusts hereby created by giving notice thereof to the Depositor and all of the Certificateholders. Upon receiving such notice of resignation, the Depositor (with the consent of Holders of a Majority in Interest of each Class of Certificates) shall promptly appoint a successor trustee by written instrument, in duplicate, which instrument shall be delivered to the resigning Trustee and to the successor trustee. A copy of such instrument shall be delivered to the Certificateholders 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 notice of removal (as provided below), the resigning or removed Trustee may petition any court of competent jurisdiction for the appointment of a successor trustee.

If at any time the Trustee shall cease to be eligible in accordance with the provisions of Section 5.06 hereof and shall fail to resign after written request therefor by the Depositor or any Certificateholder, or if at any time the Trustee shall become incapable of acting, or shall be adjudged 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, reorganization, conservation or liquidation, or if the rating of the Certificates is downgraded by a Rating Agency due to the Trustee, then the Depositor, unless instructed otherwise by Holders of a Majority in Interest of each Class of Book-Entry Certificates, shall remove the Trustee and appoint a successor trustee by written instrument, in duplicate, which instrument shall be delivered to the Trustee so removed and to the successor trustee. A copy of such instrument shall be delivered to the Certificateholders by the successor trustee.

Any resignation or removal of the Trustee and appointment of a successor trustee pursuant to any of the provisions of this Section shall not become effective until acceptance of appointment by the successor trustee as provided in Section 5.08 hereof.

Section 5.08.

Successor Trustee. Any successor trustee appointed as provided in Section 5.07 hereof shall execute, acknowledge and deliver to each of the Depositor, the Certificateholders and its predecessor trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor trustee shall become effective and such successor trustee, without any further act, deed or conveyance, shall become fully vested with all the rights, powers, duties and obligations of its predecessor hereunder, with the like effect as if originally named as Trustee herein. The predecessor trustee shall deliver to the successor trustee the Underlying Security and all related documents and statements held by it hereunder, and the Depositor and the predecessor trustee shall execute and deliver such instruments and do such other things as may reasonably be required for more fully and certainly vesting and confirming in the successor trustee all the rights, powers, duties and obligations of the Trustee under this Trust Agreement.

No successor trustee shall accept appointment as provided in this Section 5.08 unless at the time of such acceptance such successor trustee shall be eligible under the provisions of Section 5.06 hereof.

Upon acceptance of appointment by a successor trustee as provided in this Section 5.08, the successor trustee shall mail notice of the succession of such trustee hereunder to all Holders of Certificates at their addresses as shown in the Certificate Register.

Section 5.09.

Merger or Consolidation of Trustee. Any corporation (or other Person) into which the Trustee may be merged or converted or with which it may be consolidated or any corporation (or other Person) resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation (or other Person) succeeding to all or substantially all of the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such corporation (or other Person) shall be eligible under the provisions of Section 5.06 hereof, without the execution or filing of any paper or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding.

Section 5.10.

Appointment of Co-Trustee or Separate Trustee. Notwithstanding any other provisions hereof, at any time, for the purpose of meeting any legal requirements of any jurisdiction in which any part of the Trust Fund or any property securing the same may at the time be located, the Depositor and the Trustee acting jointly shall have the power and shall execute and deliver all instruments to appoint one or more Persons approved by the Trustee to act as co-trustee or co-trustees, jointly with the Trustee, or separate trustee or separate trustees, of all or any part of any Trust Fund at the expense of the Trust Fund, and to vest in such Person or Persons, in such capacity, such title to the related Trust Fund, or any part thereof, and, subject to the other provisions of this Section 5.10, such powers, duties, obligations, rights and trusts as the Depositor and the Trustee may consider necessary or desirable. If the Depositor shall not have joined in such appointment within 15 days after the receipt by it of a request so to do, the Trustee alone shall have the power to make such appointment. No co-trustee or separate trustee hereunder shall be required to meet the terms of eligibility as a successor trustee under Section 5.06 hereunder and no notice to Holders of Certificates of the appointment of co-trustee(s) or separate trustee(s) shall be required under Section 5.08 hereof.

Every separate trustee and co-trustee shall, to the extent permitted by law, be appointed and act subject to the following provisions and conditions:

(i)

All rights, powers, duties and obligations conferred or imposed upon the Trustee shall be conferred or imposed upon and exercised or performed by the Trustee and such separate trustee or co-trustee jointly (it being understood that such separate trustee or co-trustee is not authorized to act separately without the Trustee joining in such act), except to the extent that under any law of any jurisdiction in which any particular act or acts are to be performed (as Trustee hereunder), the Trustee shall be incompetent or unqualified to perform such act or acts, in which event such rights, powers, duties and obligations (including the holding of title to the related Trust Fund or any portion thereof in any such jurisdiction) shall be exercised and performed singly by such separate trustee or co-trustee, but solely at the direction of the Trustee;

(ii)

No trustee hereunder shall be held personally liable by reason of any act or omission of any other trustee hereunder; and

(iii)

The Depositor and the Trustee acting jointly may at any time accept the resignation of or remove any separate trustee or co-trustee.

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

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

Section 5.11.

Trustee’s Fees. The Trustee shall be entitled to receive, and is authorized to pay to itself, on a monthly basis, the Trustee Fee. In addition, the Trustee will be entitled to recover from the Certificate Account (subject to the limitations set forth in Section 3.04(a)(ii)) all reasonable out-of-pocket expenses, disbursements and advances, including without limitation, in connection with any breach of this Agreement or any claim or legal action (including any pending or threatened claim or legal action) incurred or made by the Trustee in the performance of its duties or the administration of the trusts hereunder; provided, however, that the Trustee shall not be reimbursed for any such expense, disbursement or advance as may arise from its negligence or intentional misconduct, and provided, further, that expenses owed to the Trustee hereunder shall not include expenses payable or paid by the related Underlying Trust Fund on the Underlying Certificates to the Trustee in its capacity as Trustee with respect to the Underlying Trust Fund. The Trustee may, but shall not be obligated to, incur costs and expenses in excess of the annual $300,000 limit set forth in Section 3.04(a)(ii) and shall have no liability to the Certificateholders or the Trust Fund for not incurring such excess costs and expenses.

Section 5.12.

Limitation of Liability. The Certificates are executed and countersigned by the Trustee, not in its individual capacity but solely as Trustee of the trust created by this Trust Agreement, in the exercise of the powers and authority conferred and vested in it by this Trust Agreement. Each of the undertakings and agreements made on the part of the Trustee on behalf of the Trust Fund in the Certificates is made and intended not as a personal undertaking or agreement by the Trustee but is made and intended for the purpose of binding only the Trust Fund.

Section 5.13.

Filings. (a) The Trustee shall reasonably cooperate with the Depositor in connection with the satisfaction of the reporting requirements under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The Trustee shall prepare on behalf of the Trust Fund any Forms 8-K and 10-K customary for similar securities as required by the Exchange Act and the Rules and Regulations of the Securities and Exchange Commission (the “Commission”) thereunder, and shall file (via the Commission’s Electronic Data Gathering and Retrieval System) any Form 8-K on behalf of the Depositor. The Depositor hereby grants to the Trustee a limited power of attorney to execute and file each such Form 8-K. Such power of attorney shall continue until the earlier of (i) receipt by the Trustee from the Depositor of written termination of such power of attorney and (ii) the termination of the Trust Fund. The Depositor shall execute and the Trustee shall file the Forms 10-K. The Trustee shall have no liability with respect to any failure to properly prepare or file such periodic reports resulting from or relating to the Trustee’s inability or failure to obtain any information not resulting from its own negligence or willful misconduct.

(b)

Each Form 8-K shall be filed by the Trustee within 15 days after each Distribution Date, with a copy of the statement to Certificateholders for such Distribution Date as an exhibit thereto. Each Form 10-K (in substance as required by applicable law or interpretations of the Commission) shall be filed by the Trustee prior to March 30th of each year (or such earlier date as may be required by the Exchange Act or the Rules and Regulations of the Commission). The Trustee shall have no liability with respect to any failure to properly prepare or file such periodic reports resulting from or relating to the Trustee’s inability or failure to obtain any information not resulting from its own negligence or willful misconduct. Each Form 10-K shall be signed by an appropriate officer of the Depositor and shall include the certification required pursuant to the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act of 2002, as amended from time to time, and any rules promulgated thereunder by the Commission (the “Form 10-K Certification”), which certification shall be signed by an appropriate officer of the Depositor. The Trustee shall prepare and deliver each Form 10-K to the Depositor for execution no later than March 15th of each year and the Depositor shall return such executed Form 10-K and an executed Form 10-K Certification to the Trustee for filing no later than March 25th of each year.

(c)

In addition, the Trustee shall sign a certification (in the form attached hereto as Exhibit H) for the benefit of the Depositor and its officers, directors and affiliates.

In addition, the Trustee shall indemnify and hold harmless the Depositor and its officers, and directors from and against losses, damages (except for special, indirect or consequential loss or damage) penalties, fines, forfeitures, reasonable and necessary legal fees and related costs, judgments and other costs and expenses arising out of or based upon an intentional breach by the Trustee of its obligations under this Section 5.13(c) or the Trustee’s negligence, bad faith or willful misconduct in connection therewith.

(d)

Upon any filing with the Commission, the Trustee shall promptly deliver to the Depositor a copy of any executed report, statement or information.

(e)

Prior to January 30th of the first year in which the Trustee is able to do so under applicable law, the Trustee shall file a Form 15D Suspension Notification with respect to the Trust Fund.

(f)

In addition, notwithstanding any prior filing of the Suspension Notification referred to in paragraph (e) above, and unless directed otherwise by the Depositor, the Trustee shall:

(i)

file by means of a Form 8-K within 15 days after each Distribution Date, a copy of the monthly statement to holders of the Underlying Security. Such filings may be included in the filings referred to in paragraph (b) above, until the Suspension Notification referred to in paragraph (e) has been filed and thereafter shall be filed separately; and

(ii)

file by means of a Form 10-K executed by the Depositor prior to March 30th of each year copies of the following documents: (A) each monthly statement filed pursuant to paragraph (i) above during the preceding calendar year; (B) the annual statement of compliance pursuant to Section 3.18 of the Underlying Agreement; (C) the annual accountant’s servicing report pursuant to Section 3.19 of the Underlying Agreement; and (D) such other documents and certificates as the Depositor shall require.

ARTICLE VI

THE DEPOSITOR

Section 6.01.

Liability of the Depositor. The Depositor shall be liable in accordance herewith only to the extent of the obligations specifically imposed upon and undertaken by the Depositor herein.

Section 6.02.

Merger, Consolidation or Conversion of the Depositor. Subject to the following paragraph, the Depositor will keep in full effect its existence, rights and franchises as a corporation under the laws of one of the states of the United States, and will obtain and preserve its qualification to do business as a foreign corporation in each jurisdiction in which such qualification is or shall be necessary to protect the validity and enforceability of this Trust Agreement and the Certificates and to perform its duties under this Trust Agreement.

The Depositor may be merged or consolidated with or into any Person, or transfer all or substantially all of its assets to any Person, in which case any Person resulting from any merger or consolidation to which the Depositor shall be a party, or any Person succeeding to the business of the Depositor, shall be the successor of the Depositor hereunder without the execution or filing of any paper or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding.

Section 6.03.

Limitation on Liability of the Depositor and Others. Neither the Depositor nor any of the directors, officers, employees or agents of the Depositor shall be under any liability to the Trust Fund or the Certificateholders for any action taken or for refraining from the taking of any action in good faith pursuant to this Trust Agreement, or for errors in judgment; provided, however, that this provision shall not protect the Depositor or any such Person against any breach of warranties or representations made by it herein, or against any liability which would otherwise be imposed by reason of willful misfeasance, bad faith or negligence in the performance of duties or by reason of reckless disregard of its obligations and duties hereunder. The Depositor and any director, officer, employee or agent of the Depositor may rely in good faith on any document of any kind which, prima facie, is properly executed and submitted by any Person respecting any matters arising hereunder.

The Depositor may in its discretion undertake any such action which Holders of a Majority in Interest of each Class of Certificates may deem necessary or desirable with respect to this Trust Agreement and the rights and duties of the parties hereto and the interests of the Certificateholders hereunder. In such event, the legal expenses and costs of such action and any liability resulting therefrom shall be expenses, costs and liabilities of the Trust Fund, and the Depositor shall be entitled to be reimbursed therefor from the Certificate Account upon delivery to the Trustee of an Officers’ Certificate stating the amount of such expenses, costs and liabilities and that such expenses, costs and liabilities are reimbursable in accordance with this Trust Agreement.

The Depositor, at its expense shall cause a nationally recognized firm of independent public accountants to furnish a statement to the Trustee on or before March 15, of each year, commencing in 2004, to the effect that, with respect to the most recently ended fiscal year, such firm has examined certain records and documents relating to the Depositor’s and Trustee’s performance of its administrative obligations under this Agreement and that, on the basis of such examination conducted substantially in compliance with the Review Procedure, the firm is of the opinion that the Depositor’s and Trustee’s activities have been conducted in compliance with this Agreement, or that such examination has disclosed no material items of noncompliance except for (i) such exceptions as such firm believes to be immaterial or (ii) such other exceptions as are set forth in such statement.

Section 6.05.

The Depositor shall deliver to the Trustee no later than five Business Days after the fifteenth of March of each calendar year, commencing in March 2004, an officer’s certificate, certifying that with respect to the period ending on the immediately preceding December 31: (i) an officer of the Depositor has reviewed the activities of the Depositor and Trustee during the preceding calendar year or portion thereof and its performance under this Agreement, or (ii) to the best of such officer’s knowledge, based on such review, the Depositor and Trustee have performed and fulfilled their duties, responsibilities and obligations under this Agreement in all material respects throughout such year, or, if there has been a default in the fulfillment of any such duties, responsibilities or obligations, specifying each such default known to such officer and the nature and status thereof.

ARTICLE VII

TERMINATION

Section 7.01.

Termination. (a) Subject to Section 7.02 hereof, the respective obligations and responsibilities of the Depositor and the Trustee created hereby with respect to the Certificates (other than the obligation to make certain payments and to send certain notices to Certificateholders as hereinafter set forth) shall terminate immediately upon the occurrence of the last action required to be taken by the Trustee on the Distribution Date pursuant to this Article VII following the receipt of the final distribution to be made on the Underlying Security to remain outstanding upon presentment and surrender of the Underlying Security in accordance with the terms and conditions of the Underlying Agreement; provided, however, that in no event shall the trust created hereby continue beyond the earlier of (i) the expiration of twenty-one years from the death of the last survivor of the descendants of ▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇, the late ambassador of the United States to the Court of St. James’s, living on the date hereof.

(b)

Notice of the final distribution in respect of any Class of Certificates, specifying the Distribution Date upon which all Holders of Certificates of such Class may surrender their Certificates to the Trustee for payment and cancellation, shall be given by the Trustee to Certificateholders as promptly as practicable following the notice of the final distribution on the Underlying Security. Such notice shall specify (i) the Distribution Date upon which final payment on the related Certificates will be made upon presentment and surrender of such Certificates at the office or agency appointed by the Trustee for that purpose, (ii) the amount of any such final payment and (iii) that the Record Date otherwise applicable to such Distribution Date is not applicable and that payments shall be made only upon presentation and surrender of such Certificates at the office or agency of the Trustee therein specified. Upon presentment and surrender of the related Certificates, the Trustee shall cause to be distributed to the related Certificateholders an amount equal to the amount otherwise distributable on such Distribution Date.

Any funds not distributed on the final Distribution Date for the related Class of Certificates because of the failure of any such Certificateholders to tender their Certificates shall be set aside and held uninvested in trust for the account of the appropriate non-tendering Certificateholders, whereupon the Trust Fund shall terminate. If any Certificates as to which notice of the final Distribution Date has been given pursuant to this Section 7.01 shall not have been surrendered for cancellation within six months after the time specified in such notice, the Trustee shall mail a second notice to the remaining Certificateholders, at their last addresses shown in the Certificate Register, to surrender their Certificates for cancellation in order to receive, from such funds held, the final distribution with respect thereto. If within one year after the second notice any Certificate shall not have been surrendered for cancellation, the Trustee shall, directly or through an agent, take reasonable steps to contact the remaining Certificateholders concerning surrender of their Certificates. The costs and expenses of maintaining such funds and of contacting Certificateholders shall be paid out of the assets which remain held. If within two years any Certificates shall not have been surrendered for cancellation, the Trustee shall pay to the Depositor all amounts distributable to the Holders thereof and the Depositor shall thereafter hold such amounts for the benefit of such Holders. No interest shall accrue or be payable to any Certificateholder on any amount held as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with this Section 7.01.

Section 7.02.

Additional Termination Requirements. (a) The REMIC shall be terminated in accordance with the following additional requirements, unless the Trustee has been supplied with an Opinion of Counsel, which Opinion of Counsel shall not be an expense of the Trustee, to the effect that the failure of the REMIC to comply with the requirements of this Section 7.02 will not (i) result in the imposition of taxes on “prohibited transactions” of the REMIC as defined in section 860F of the Code, or (ii) cause the REMIC to fail to qualify as a REMIC at any time that any Certificates relating thereto are outstanding:

(i)

Within 90 days prior to the final Distribution Date for the REMIC set forth in the notice to Certificateholders given under Section 7.01, the Depositor shall use reasonable efforts to cause the Holder of the Residual Certificate to adopt, and such Holder shall adopt, a plan of complete liquidation of the REMIC within the meaning of section 860F(a)(4) of the Code and shall prepare and shall deliver to the Trustee such plan of complete liquidation; and

(ii)

Within 90 days after the time of adoption of such a plan of complete liquidation and at or prior to the final Distribution Date, the Trustee shall, upon receipt of all documentation associated with such plan of complete liquidation, sell or otherwise dispose of all of the assets of the REMIC, in a time and manner specified by such plan of complete liquidation.

(b)

By its acceptance of the Residual Certificate, the Holder thereof hereby agrees: (i) to the appointment of the Trustee as agent for the REMIC and as agent for the Tax Matters Person, and (ii) to the adoption by the Trustee as agent for the Tax Matters Person of a plan of complete liquidation with respect to the REMIC upon the written request of, and to take such other action in connection therewith as may be reasonably requested by, the Depositor or the Holder of the Residual Certificate.

(c)

The Trustee as agent for the REMIC hereby agrees to adopt and sign such a plan of complete liquidation upon the written request of the Depositor and, if the Depositor requests a plan not in compliance with Section 7.02(a), the receipt of the Opinion of Counsel referred to in Section 7.02(a) hereof, and to take such other action in connection therewith as may be reasonably requested by the Depositor.

This Trust Agreement may also be amended by the Depositor and the Trustee with the consent of the holders of a Majority in Interest of each Class of Certificates affected thereby for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Trust Agreement or of modifying in any manner the rights of the holders of Certificates; provided, however, that no such amendment may (a) reduce in any manner the amount of, or delay the timing of, distributions required to be made on any Certificate without the consent of the holder of such Certificate, (b) adversely affect in any material respect the interest of the holders of the Certificates of any Class in a manner other than as described in clause (a) above without the consent of the holders of Certificates of such Class representing not less than 66% of the Percentage Interests represented by such Class or (c) reduce the aforesaid percentages of Certificates the holders of which are required to consent to any such amendment without the consent of the holders of all Certificates then outstanding.

Notwithstanding any contrary provision of this Trust Agreement, the Trustee shall not consent to any amendment to this Trust Agreement unless it shall have first received at the expense of the Person requesting such amendment (or, in the event such amendment is requested by the Trustee, at the expense of the Depositor), an Opinion of Counsel to the effect that such amendment will not cause the Trust Fund to fail to qualify as a REMIC at any time that any Certificates are Outstanding.

Promptly after the execution of any such amendment the Trustee shall furnish a copy of the amendment or a statement describing it to each Certificateholder.

The manner of obtaining such consents and of evidencing the authorization of the execution thereof by Certificateholders shall be subject to such reasonable regulations as the Trustee may prescribe.

Prior to executing any amendment, the Trustee shall be entitled to receive and rely upon an Opinion of Counsel, stating that the execution of such amendment is authorized or permitted by this Trust Agreement.

In the absence of any the instructions, the Trustee shall not vote the Underlying Security; provided, however, that notwithstanding the absence of such instructions, in the event a required distribution pursuant to the Underlying Agreement shall not have been made, the Trustee shall notify the Holders and, subject to the provisions of this Agreement, pursue such remedies as are directed by Holders of a Majority in Interest of the Certificates and which are available to it as holder of the Underlying Security in accordance with the terms of the Underlying Agreement.

Section 8.03.

Section 8.04.

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

No Certificateholder shall have any right to vote (except as expressly provided for 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 Trust Agreement pursuant to any provision hereof.

No Certificateholder shall have any right by virtue of any provision of this Trust Agreement to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Trust Agreement, unless such Holder previously shall have given to the Trustee a notice of a default by the Depositor or the Trustee in the performance of any obligation hereunder, and of the continuance thereof, as hereinbefore provided, and unless also the Holders of Certificates evidencing Percentage Interests in each Class of Certificates aggregating at least 25% shall have made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder and shall have offered to the Trustee such indemnity reasonably satisfactory to it as it may require against the costs, expenses and liabilities to be incurred therein or thereby, and the Trustee, for 60 days after its receipt of such notice, request and offer of indemnity, shall have neglected or refused to institute any such action, suit or proceeding. It is understood and intended, and expressly covenanted by each Certificateholder with every other Certificateholder and the Trustee, that no one or more Holders of Certificates shall have any right in any manner whatever by virtue of any provision of this Trust Agreement to affect, disturb or prejudice the rights of the Holders of any other Certificates, or to obtain or seek to obtain priority over or preference to any other such Holder, or to enforce any right under this Trust Agreement, except in the manner herein provided.

)

The undersigned, being first duly sworn, deposes and says as follows:

The undersigned is an officer of ______________________, the proposed Transferee of a 100% Ownership Interest in the Class A-R Certificate (the “Certificate”) issued pursuant to the Trust Agreement (the “Agreement”) dated as of October 1, 2003, relating to the above-referenced Certificates, between Greenwich Capital Acceptance, Inc., as Depositor and Deutsche Bank National Trust Company, as Trustee. Capitalized terms used, but not defined herein, shall have the meanings ascribed to such terms in the Agreement. The Transferee has authorized the undersigned to make this affidavit on behalf of the Transferee.

The Transferee is, as of the date hereof, and will be, as of the date of the Transfer, a Permitted Transferee. The Transferee is acquiring its Ownership Interest for its own account and not in a capacity as trustee, nominee or agent for another party.

The Transferee has been advised of, and understands that (i) a tax will be imposed on Transfers of the Certificate to Persons that are not Permitted Transferees; (ii) such tax will be imposed on the transferor, or, if such Transfer is through an agent (which includes a broker, nominee or middleman) for a Person that is not a Permitted Transferee, on the agent; and (iii) the Person otherwise liable for the tax shall be relieved of liability for the tax if the subsequent Transferee furnished to such Person an affidavit that such subsequent Transferee is a Permitted Transferee and, at the time of Transfer, such Person does not have actual knowledge that the affidavit is false. The Transferee has provided financial statements or other financial information requested by the Transferor in connection with the transfer of the Certificate to permit the Transferor to assess the financial capability of the Transferee to pay such taxes.

The Transferee has been advised of, and understands that a tax may be imposed on a “pass-through entity” holding the Certificate if, at any time during the taxable year of the pass-through entity, a Disqualified Organization is the record holder of an interest in such entity. The Transferee understands that such tax will not be imposed for any period with respect to which the record holder furnishes to the pass-through entity an affidavit that such record holder is not a Disqualified Organization and the pass-through entity does not have actual knowledge that such affidavit is false. (For this purpose, a “pass-through entity” includes a regulated investment company, a real estate investment trust or common trust fund, a partnership, trust or estate, and certain cooperatives and, except as may be provided in Treasury Regulations, persons holding interests in pass through entities as a nominee for another Person.)

The Transferee has reviewed the provisions of Section 6.02(e) of the Agreement and understands the legal consequences of the acquisition of an Ownership Interest in the Certificate including, without limitation, the restrictions on subsequent Transfers and the provisions regarding voiding the Transfer and mandatory sales. The Transferee expressly agrees to be bound by and to abide by the provisions of Section 6.02(e) of the Agreement and the restrictions noted on the face of the Certificate. The Transferee understands and agrees that any breach of any of the representations included herein shall render the Transfer to the Transferee contemplated hereby null and void.

The Transferee agrees to require a Transfer Affidavit from any Person to whom the Transferee attempts to Transfer its Ownership Interest in the Certificate, and the Transferee will not Transfer its Ownership Interest or cause any Ownership Interest to be Transferred to any Person that the Transferee knows is not a Permitted Transferee. In connection with any such Transfer by the Transferee, the Transferee agrees to deliver to the Trustee a certificate substantially in the form set forth as Exhibit K to the Agreement (a “Transferor Certificate”).

The Transferee does not have the intention to impede the assessment or collection of any tax legally required to be paid with respect to the Certificate.

The Transferee’s taxpayer identification number is .

The Transferee is aware that the Certificate may be a “noneconomic residual interest” within the meaning of the REMIC provisions and that the transferor of a noneconomic residual interest will remain liable for any taxes due with respect to the income on such residual interest, unless no significant purpose of the transfer was to impede the assessment or collection of tax.

IN WITNESS WHEREOF, the Transferee has caused this instrument to be executed on its behalf, pursuant to authority of its Board of Directors, by its duly Authorized Officer and its corporate seal to be hereunto affixed, duly attested, this day of , 20 .
