     Section 2.06.  Declaration of Trust. The Trustee hereby declares that it
will hold the Trust Estate in trust upon and subject to the conditions set forth

     (a)  Notwithstanding the provisions of Section 3803 of the Delaware
Statutory Trust Act, the Depositor shall be liable directly to and shall
indemnify the injured party for all losses, claims, damages, liabilities and
expenses of the Trust (including Expenses, to the extent that the assets of the
Trust that would remain if all of the Notes were paid in full would not be
sufficient to pay any such liabilities, or if such liabilities in fact are not
paid out of the Trust Estate) to the extent that the Depositor would be liable
if the Trust were a partnership under the Delaware Revised Uniform Limited

however, that the Depositor shall not be liable for any losses incurred by a
beneficial owner of a Note in its capacity as a holder of limited recourse debt
or to any holder of the Excess Distribution Certificate. In addition, any third
party creditors of the Trust (other than in connection with the obligations to

     Section 2.08.  Title to Trust Property. Legal title to all of the Trust
Estate shall be vested at all times in the Trust as a separate legal entity
except where applicable law in any jurisdiction requires title to any part of
the Trust Estate to be vested in a trustee or trustees, in which case title
shall be deemed to be vested in the Trustee, a co-trustee and/or a separate
trustee, as the case may be.

     Section 2.09.  Representations, Warranties, and Covenants of the Depositor.
The Depositor hereby represents, warrants and covenants to the Trustee as
follows:

     (a)  The Depositor is duly organized and validly existing as a Delaware
limited liability company in good standing under the laws of the State of
Delaware, with power and authority to own its properties and to conduct its

Agreement and to carry out its terms; the Depositor has full power and authority
to sell and assign the property to be sold and assigned to and deposited with
the Trust and the Depositor has duly authorized such sale and assignment and
deposit to the Trust by all necessary action; and the execution, delivery and
performance of this Agreement has been duly authorized by the Depositor by all
necessary action.

                                        3

<PAGE>

     (c)  This Agreement constitutes a legal, valid and binding obligation of
the Depositor enforceable in accordance with its terms, subject to applicable
bankruptcy, insolvency, reorganization and similar laws relating to creditors'
rights generally and subject to general principles of equity.

     (d)  The consummation of the transactions contemplated by this Agreement
and the fulfillment of the terms hereof do not conflict with, result in any
breach of any of the terms and provisions of, or constitute (with or without
notice or lapse of time or both) a default under, the Certificate of Formation
or Limited Liability Company Operating Agreement of the Depositor, or any
indenture, agreement or other instrument to which the Depositor is a party or by

other instrument (other than pursuant to the Basic Documents); nor violate any
law or, to the Depositor's knowledge, any order, rule or regulation applicable
to the Depositor of any court or of any Federal or state regulatory body,
administrative agency or other governmental instrumentality having jurisdiction
over the Depositor or its properties.

     (e)  The Depositor agrees for the benefit of the Noteholders and the holder
of the Excess Distribution Certificate that it will comply with each of the
requirements set forth in its Certificate of Formation or Limited Liability
Company Operating Agreement.

                                   ARTICLE III

                            BENEFICIAL OWNERSHIP AND
                         EXCESS DISTRIBUTION CERTIFICATE

     Section 3.01.  Initial Beneficial Ownership. Upon the formation of the
Trust by the contribution by the Depositor pursuant to Section 2.05 and until
the issuance of the Excess Distribution Certificate, the Depositor shall be the
sole beneficial owner of the Trust.

     Section 3.02.  Corporate Trust Office. The Trustee initially designates
Christiana Center/OPS4, 500 Stanton Christiana Road, Newark, Delaware 19713, as
its principal Corporate Trust Office, at which it shall act as Trustee of the
Trust. The Excess Distribution Certificate Registrar's New York office and its
authenticating agent's office are located at 450 West 33rd Street, 15th Floor,
New York, New York 10001, Attention: Structured Finance Services.

     Section 3.03.  The Excess Distribution Certificate.

     (a)  General. The Excess Distribution Certificate shall be issued in one or
more registered, definitive, physical certificates substantially in the form of
Exhibit A hereto, in minimum percentage interests of at least 10% and integral
multiples of 10% in excess thereof. The Excess Distribution Certificate shall
receive payments as provided in Section 2.07(c)(xvii) and Section 2.08 of the
Administration Agreement. The Excess Distribution Certificate shall be executed
on behalf of the Trust by manual or facsimile signature of an authorized officer
of the Trustee. An Excess Distribution Certificate bearing the manual or
facsimile signatures of individuals who were, at the time when such signatures
were affixed, authorized to sign on

                                        4

<PAGE>

behalf of the Trust, shall be valid and binding obligations of the Trust,
notwithstanding that such individuals or any of them shall have ceased to be so
authorized prior to the authentication and delivery of such Excess Distribution
Certificate or did not hold such offices at the date of authentication and
delivery of such Excess Distribution Certificate.

     (b)  Authentication. Concurrently with the sale of the Trust Student Loans
to the Trust pursuant to the Depositor Sale Agreement, the Trustee shall cause
the Excess Distribution Certificate to be executed on behalf of the Trust,
authenticated and delivered to or upon the written order of the Depositor,
signed by its chairman of the board, its president or any vice president,
without further action by the Depositor. No Excess Distribution Certificate
shall entitle its holder to any benefit under this Agreement, or shall be valid
for any purpose, unless there shall appear on such Excess Distribution
Certificate a certificate of authentication substantially in the form set forth
in Exhibit A, executed by the Trustee or JPMorgan Chase Bank, as the Trustee's
authenticating agent, by manual signature; such authentication shall constitute
conclusive evidence that such Excess Distribution Certificate shall have been
duly authenticated and delivered hereunder. The Excess Distribution Certificate
shall be dated the date of its authentication. No further Excess Distribution
Certificates shall be issued except pursuant to clause (c) or (d) below.

     (c)  Registration of Transfer and Exchange. The Excess Distribution
Certificate Registrar shall keep or cause to be kept, at the office or agency
maintained pursuant to clause (f) below, an Excess Distribution Certificate
Register in which, subject to such reasonable regulations as it may prescribe,
the Trustee shall provide for the registration of the Excess Distribution
Certificate and of transfers and exchanges of the Excess Distribution
Certificate as herein provided. JPMorgan Chase Bank shall be the initial Excess
Distribution Certificate Registrar.

     Upon surrender for registration of transfer of the Excess Distribution
Certificate at the office or agency maintained pursuant to clause (f) below, the
Trustee shall execute, authenticate and deliver (or shall cause JPMorgan Chase
Bank as its authenticating agent to authenticate and deliver), in the name of
the designated transferee, a new Excess Distribution Certificate dated the date
of authentication by the Trustee or any authenticating agent. At the option of
the holder of the Excess Distribution Certificate, the Excess Distribution
Certificate may be exchanged for another Excess Distribution Certificate upon
surrender of the Excess Distribution Certificate to be exchanged at the office
or agency maintained pursuant to clause (f) below.

     An Excess Distribution Certificate presented or surrendered for
registration of transfer or exchange shall be accompanied by a written
instrument of transfer in form satisfactory to the Excess Distribution
Certificate Registrar duly executed by the holder thereof or his attorney duly
authorized in writing, with such signature guaranteed by a member firm of the
New York Stock Exchange or a commercial bank or trust company. An Excess
Distribution Certificate surrendered for registration of transfer or exchange
shall be cancelled and subsequently disposed of by the Excess Distribution
Certificate Registrar in accordance with its customary practice.

     No service charge shall be made for any registration of transfer or
exchange of the Excess Distribution Certificate, but the Excess Distribution
Certificate Registrar may require payment of

                                        5

<PAGE>

a sum sufficient to cover any tax or governmental charge that may be imposed in
connection with any transfer or exchange of the Excess Distribution Certificate.

     The preceding provisions of this Section notwithstanding, the Trustee shall
not be required to make and the Excess Distribution Certificate Registrar need
not register transfers or exchanges of the Excess Distribution Certificate for a
period of 15 days preceding any Distribution Date with respect to the Excess
Distribution Certificate.

     The Excess Distribution Certificate and any beneficial interest in the
Excess Distribution Certificate may not be acquired by (i) employee benefit
plans (as defined in section 3(3) of ERISA) that are subject to the provisions
of Title I of ERISA, (ii) plans described in section 4975(e)(1) of the Code,
including individual retirement accounts described in Section 408(a) of the Code
or Keogh plans, (iii) Benefit Plans, (iv) any person who is not a United States
person within the meaning of section 7701(a)(3) of the Code, or (v) any
"pass-thru entity" referred to in section 1(h)(10)(D), (E) or (F) of the Code,
the income of which pass-thru entity is includible by any person referred to in
clause (iv) above. By accepting and holding the Excess Distribution Certificate
or an interest therein, the holder thereof shall be deemed to have represented
and warranted that it is not a Benefit Plan or any other person referred to in
Clauses (i) through (v) of the preceding sentence, is not purchasing the Excess
Distribution Certificate on behalf of a Benefit Plan or any other person
referred to in Clauses (i) through (v) of the preceding sentence and is not
using assets of a Plan to purchase the Excess Distribution Certificate and to
have agreed that if the Excess Distribution Certificate is deemed to be a plan
asset, the holder thereof will promptly dispose of the Excess Distribution
Certificate. The provisions of Sections 7.01, 7.03, 7.04, 7.05, 8.01 and 8.03
shall apply to the Indenture Trustee also in its role as Excess Distribution
Certificate Registrar, for so long as the Indenture Trustee shall act as Excess
Distribution Certificate Registrar and, to the extent applicable, to any other
certificate registrar appointed hereunder.

     (d)  Mutilated, Destroyed, Lost or Stolen Excess Distribution Certificate.
If (i) the mutilated Excess Distribution Certificate shall be surrendered to the
Excess Distribution Certificate Registrar, or if the Excess Distribution
Certificate Registrar shall receive evidence to its satisfaction of the
destruction, loss or theft of the Excess Distribution Certificate, and (ii)
there shall be delivered to the Excess Distribution Certificate Registrar and
the Trustee such security or indemnity as may be required by them to save each
of them and the Trust harmless, then in the absence of notice that such Excess
Distribution Certificate shall have been acquired by a bona fide purchaser, the
Trustee on behalf of the Trust shall execute and the Trustee shall authenticate
and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost
or stolen Excess Distribution Certificate, a new Excess Distribution Certificate
of like tenor. In connection with the issuance of any new Excess Distribution
Certificate under this Section, the Excess Distribution Certificate Registrar
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in connection therewith. Any duplicate
Excess Distribution Certificate issued pursuant to this paragraph shall
constitute conclusive evidence of ownership in the Trust, as if originally
issued, whether or not the lost, stolen or destroyed Excess Distribution
Certificate shall be found at any time.

     (e)  Persons Deemed Owners. Prior to due presentation of the Excess
Distribution Certificate for registration of transfer, the Trustee and the
Excess Distribution Certificate

                                        6

Registrar and any agent of either of them may treat the Person in whose name the
Excess Distribution Certificate shall be registered in the Excess Distribution
Certificate Register as the owner of such Excess Distribution Certificate for
the purpose of receiving distributions thereon and for all other purposes
whatsoever, and neither the Trustee, the Excess Distribution Certificate
Registrar nor any agent thereof shall be bound by any notice to the contrary.

     (f)  Maintenance of Office or Agency. The Trustee shall maintain in the
Borough of Manhattan, The City of New York, an office or offices or agency or
agencies where the Excess Distribution Certificate may be surrendered for
registration of transfer or exchange and where notices and demands to or upon
the Trustee in respect of the Excess Distribution Certificate may be served.

     (g)  Appointment of Excess Distribution Certificate Paying Agent. The
Excess Distribution Certificate Paying Agent shall make distributions to the
holder of the Excess Distribution Certificate from the amounts received from the
Indenture Trustee pursuant to Section 2.07(c)(xvii) and Section 2.08 of the
Administration Agreement and shall report the amounts of such distributions to
the Indenture Trustee (if the Excess Distribution Certificate Paying Agent is
not the Indenture Trustee). Any Excess Distribution Certificate Paying Agent
shall have the revocable power to receive such funds from the Indenture Trustee
for the purpose of making the distributions referred to above. The Trustee may
revoke such power and remove the Excess Distribution Certificate Paying Agent if
the Trustee determines in its sole discretion that the Excess Distribution
Certificate Paying Agent shall have failed to perform its obligations under this
Agreement in any material respect. The Excess Distribution Certificate Paying
Agent shall initially be the Indenture Trustee, and any co-paying agent chosen
by the Trustee and consented to by the Administrator (which consent shall not be
unreasonably withheld). The Indenture Trustee shall be permitted to resign as
Excess Distribution Certificate Paying Agent upon 30 days' written notice to the
Trustee. In the event that the Indenture Trustee shall no longer be the Excess
Distribution Certificate Paying Agent, the Trustee shall appoint a successor to
act as Excess Distribution Certificate Paying Agent (which shall be a bank or
trust company). The Trustee shall cause such successor Excess Distribution
Certificate Paying Agent or any additional Excess Distribution Certificate
Paying Agent appointed by the Trustee to execute and deliver to the Trustee an
instrument in which such successor Excess Distribution Certificate Paying Agent
or additional Excess Distribution Certificate Paying Agent shall agree with the
Trustee that as Excess Distribution Certificate Paying Agent, such successor
Excess Distribution Certificate Paying Agent or additional Excess Distribution
Certificate Paying Agent will hold all sums, if any, held by it for payment to
the holder of the Excess Distribution Certificate in trust for the benefit of
such holder until such sums shall be paid to such holder. The Excess
Distribution Certificate Paying Agent shall return all unclaimed funds to the
Trustee and upon removal of an Excess Distribution Certificate Paying Agent such
Excess Distribution Certificate Paying Agent shall also return all funds in its
possession to the Trustee. The provisions of Sections 7.01, 7.03, 7.04, 7.05,
8.01 and 8.03 shall apply to the Indenture Trustee also in its role as Excess
Distribution Certificate Paying Agent, for so long as the Indenture Trustee
shall act as Excess Distribution Certificate Paying Agent and, to the extent
applicable, to any other paying agent appointed hereunder. Any reference in this
Agreement to the Excess Distribution Certificate Paying Agent shall include any
co-paying agent unless the context requires otherwise.

     (h)  Restrictions on Transfer of the Excess Distribution Certificate. (i)
The Excess Distribution Certificate may be transferred to the Depositor or to
any Affiliate of the Depositor, without any requirement to provide any officer's
certificates or legal opinions that would otherwise be required if such proposed
transfer was being made to a Person who is not an Affiliate of the Depositor.

          (ii) Except as provided above, the Excess Distribution Certificate
     shall not be sold, pledged, transferred or assigned except as provided
     below:

               A.   The Excess Distribution Certificate has not been registered
     or qualified under the Securities Act of 1933, as amended (the "Securities
     Act") or any state securities law. No transfer, sale, pledge or other
     disposition of the Excess Distribution Certificate or any interest therein
     shall be made unless such transfer is made pursuant to an effective
     registration statement under the Securities Act and effective registration
     or qualification under applicable state securities laws, or is made in a
     transaction which does not require such registration or qualification. In
     the event that a transfer is to be made without registration or
     qualification, the Trustee shall require, in order to assure compliance
     with such laws, that the prospective transferor and transferee each certify
     to the Trustee, the Excess Distribution Certificate Registrar, the
     Administrator, and, if it is not the proposed transferor, the Depositor, in
     writing, the facts surrounding the transfer. Such certifications shall be
     substantially in the forms of Exhibits C and D-1 or D-2 hereto,
     respectively. In the event that such a transfer is to be made within two
     years from the date of the initial issuance of the Excess Distribution
     Certificate pursuant hereto (other than a transfer as to which the proposed
     transferee has provided a certificate in the form of Exhibit D-2), the
     Trustee in its sole discretion, may require that there shall also be
     delivered to the Trustee, the Excess Distribution Certificate Registrar,
     the Administrator, and, if it is not the proposed transferor, the
     Depositor, at the expense of the transferor, an opinion of counsel that
     such transfer may be made pursuant to an exemption from the Securities Act
     and such state securities laws. Any such opinion of counsel shall not be an
     expense of the Trustee, the Excess Distribution Certificate Registrar, the
     Administrator, and, if it is not the proposed transferor, the Depositor.
     None of the Depositor, the Administrator or the Trustee is obligated to
     register or qualify the Excess Distribution Certificate under the
     Securities Act or any other securities law or to take any action not
     otherwise required under this Agreement to permit the transfer of the
     Excess Distribution Certificate without registration or qualification. Any
     such holder of the Excess Distribution Certificate desiring to effect such
     transfer shall, and does hereby agree to, indemnify the Trustee, the Excess
     Distribution Certificate Registrar, the Administrator, and, if it is not
     the proposed transferor, the Depositor, against any liability that may
     result if the transfer is not so exempt or is made in accordance with such
     applicable federal and state laws.

               B.   No transfer of the Excess Distribution Certificate will be
     registered by the Trustee or the Excess Distribution Certificate Registrar
     unless the Trustee, the Certificate Registrar, the Administrator, and, if
     it is not the proposed transferor, the Depositor receives a representation
     from the proposed transferee of the Excess Distribution Certificate,
     substantially in the form of Exhibit D-1 or D-2, as the case may be, that
     such transferee is not acquiring the Excess Distribution Certificate
     directly or

                                        8

<PAGE>

     indirectly for, on behalf of or with the assets of a Plan. If any proposed
     transferee shall become a holder of the Excess Distribution Certificate in
     violation of these provisions, then the last preceding permitted transferee
     shall be restored, to the extent permitted by law, to all rights as holder
     of the Excess Distribution Certificate, retroactive to the date of
     registration of such transfer of the Excess Distribution Certificate.
     Neither the Trustee nor the Excess Distribution Certificate Registrar shall
     have any liability to any person for any registration or transfer of the
     Excess Distribution Certificate that is not permitted or for making any
     payments due on the Excess Distribution Certificate to the holder or taking
     any action with respect to such holder under this Agreement. Any proposed
     transferee who becomes a holder of the Excess Distribution Certificate
     shall agree to indemnify the Trustee, the Excess Distribution Certificate
     Registrar, the Swap Counterparty, the Administrator, if it is not the
     proposed transferor, the Cap Counterparty, and, if it is not the proposed
     transferor, the Depositor, against any loss, damage or penalty incurred as
     a result of the transfer of the Excess Distribution Certificate to such
     proposed transferee in violation of such restrictions.

               C.   The prospective transferee shall be aware that the Excess
     Distribution Certificate shall bear legends referring to the restrictions
     contained in sub-clauses (A) and (B) above and by its acceptance of the
     Excess Distribution Certificate agrees to abide by such restrictions.

               D.   The prospective transferee shall deliver an opinion of
     counsel addressed to the Trustee, the Swap Counterparty, the Administrator,
     if it is not the proposed transferor, the Cap Counterparty, and, if it is
     not the proposed transferor, the Depositor, to the effect that, (1) as a
     matter of federal income tax law, such prospective transferee is permitted
     to accept the transfer of the Excess Distribution Certificate, (2) such
     transfer or pledge would not jeopardize the tax treatment of the Trust,
     (3) such transfer or pledge would not subject the Trust to any entity-level
     tax, (4) such transfer or pledge would not jeopardize the status of the
     Notes as debt for all purposes, and (5) such pledge or transfer would not
     cause the Trust to be treated, for federal income tax purposes, as an
     association or a publicly traded partnership taxable as a corporation.

               E.   No pledge or transfer of the Excess Distribution Certificate
     shall be effective unless such purchase or transfer is to a single
     beneficial owner who shall be the registered holder of the Excess
     Distribution Certificate.

     (c)  the amendment of the Indenture by a supplemental indenture in

Excess Distribution Certificate; or

     (d)  the amendment of the Swap Agreement or an Interest Rate Cap Agreement
in circumstances where the consent of any class of Noteholders is required or in
circumstances where the consent of Noteholders is not required but where such

Distribution Certificate.

     Section 4.02.  Action with Respect to Sale of the Trust Student Loans. The
Trustee shall not have the power, except upon the written direction of the
Depositor and except as expressly provided in the Basic Documents, to sell the
Trust Student Loans after the payment in full of the Notes.

have the power to commence a voluntary proceeding in bankruptcy relating to the

reasonably believes that the Trust is insolvent.

     Section 4.04.  Restrictions. Neither the Depositor nor the holder of the
Excess Distribution Certificate shall direct the Trustee to take or refrain from
taking any action if such action or inaction would be contrary to any obligation
of the Trust or the Trustee under this Agreement or any of the other Basic
Documents or would be contrary to Section 2.03 nor shall the Trustee be
permitted to follow any such direction, if given.

written instructions signed by two authorized officers, if any, at least five
Business Days prior to such Distribution Date, or, if not, by check mailed to
such holder at the address of such holder appearing in the Excess Distribution

the Trustee shall not be liable for any interest thereon.

     Section 5.04.  Reports to the Holder of the Excess Distribution
Certificate, the Internal Revenue Service and Others. The Trustee shall provide
(or cause to be provided) any reports or other information required to be

addition, the Trustee shall provide (or cause to be provided) any information

                         AUTHORITY AND DUTIES OF TRUSTEE

     Section 6.01.  General Authority. The Trustee is authorized and directed to
execute and deliver the Basic Documents to which the Trust is to be a party and
each certificate or other document attached as an exhibit to or contemplated by
the Basic Documents to which the Trust is to be a party, in each case, in such
form as the Depositor shall approve as evidenced conclusively by the Trustee's
execution thereof, and, on behalf of the Trust, to direct the Indenture Trustee
to authenticate and deliver Notes in the aggregate principal amount of

                                       11

<PAGE>

$1,507,574,000. In addition to the foregoing, the Trustee is authorized to take
all actions required of the Trust pursuant to the Basic Documents. The Trustee
is further authorized from time to time to take such action as the Administrator
directs or instructs with respect to the Basic Documents and is directed to take
such action to the extent that the Administrator is expressly required pursuant
to the Basic Documents to cause the Trustee to act.

     Section 6.02.  General Duties. It shall be the duty of the Trustee to
discharge (or cause to be discharged) all its responsibilities pursuant to the
terms of this Agreement, the other Basic Documents to which the Trust is a party
and to administer the Trust in the interest of the Noteholders and the holder of
the Excess Distribution Certificate subject to and in accordance with the
provisions of this Agreement and the other Basic Documents. Without limiting the
foregoing, the Trustee shall on behalf of the Trust file and prove any claim or
claims that may exist on behalf of the Trust against the Depositor in connection
with any claims paying procedure as part of an insolvency or a receivership
proceeding involving the Depositor. Notwithstanding the foregoing, the Trustee
shall be deemed to have discharged its duties and responsibilities hereunder and
under the other Basic Documents to the extent the Administrator has agreed in
the Administration Agreement to perform and act or to discharge any duty of the
Trustee hereunder or under any other Basic Document, and the Trustee shall not
be held liable for the default or failure of the Administrator to carry out its
obligations under the Administration Agreement. Except as expressly provided in
the Basic Documents, the Trustee shall have no obligation to administer, service
or collect the Trust Student Loans or to maintain, monitor or otherwise
supervise the administration, servicing or collection of the Trust Student
Loans.

     Section 6.03.  Action Upon Instruction.

     (a)  Reserved.

     (b)  The Trustee shall not be required to take any action hereunder or
under any other Basic Document if the Trustee shall have reasonably determined,
or shall have been advised by counsel, that such action is likely to result in
liability on the part of the Trustee or is contrary to the terms hereof, any
other Basic Document or is otherwise contrary to law.

     (c)  Whenever the Trustee is unable to determine the appropriate course of
action between alternative courses and actions permitted or required by the
terms of this Agreement or under any other Basic Document, the Trustee shall
promptly give notice (in such form as shall be appropriate under the
circumstances) to the Depositor requiring instruction as to the course of action
to be adopted, and to the extent the Trustee acts in good faith in accordance
with any written instruction of the Depositor received, the Trustee shall not be
liable on account of such action to any Person. If the Trustee shall not have
received appropriate instruction within 10 days of such notice (or within such
shorter period of time as reasonably may be specified in such notice or may be
necessary under the circumstances) it may, but shall be under no duty to, take
or refrain from taking such action, not inconsistent with this Agreement, the
other Basic Documents, as it shall deem to be in the best interests of the
Depositor, and shall have no liability to any Person for such action or
inaction.

<PAGE>

     (d)  In the event that the Trustee is unsure as to the application of any
provision of this Agreement, any other Basic Document or any such provision is
ambiguous as to its application, or is, or appears to be, in conflict with any
other applicable provision, or in the event that this Agreement permits any
determination by the Trustee or is silent or is incomplete as to the course of
action that the Trustee is required to take with respect to a particular set of
facts, the Trustee may give notice (in such form as shall be appropriate under
the circumstances) to the Depositor requesting instruction and, to the extent
that the Trustee acts or refrains from acting in good faith in accordance with
any such instruction received, the Trustee shall not be liable, on account of
such action or inaction, to any Person. If the Trustee shall not have received
appropriate instruction within 10 days of such notice (or within such shorter
period of time as reasonably may be specified in such notice or may be necessary
under the circumstances) it may, but shall be under no duty to, take or refrain
from taking such action, not inconsistent with this Agreement or the other Basic
Documents, as it shall deem to be in the best interest of the holder of the
Excess Distribution Certificate, and shall have no liability to any Person for
such action or inaction.

     Section 6.04.  No Duties Except as Specified in this Agreement or in
Instructions. The Trustee shall not have any duty or obligation to manage, make
any payment with respect to, register, record, sell, service, dispose of or
otherwise deal with the Trust Estate, or to otherwise take or refrain from
taking any action under, or in connection with, any document contemplated hereby
to which the Trustee is a party, except as expressly provided by the terms of
this Agreement or in any document or written instruction received by the Trustee
pursuant to Section 6.03; and no implied duties or obligations shall be read
into this Agreement or any other Basic Document against the Trustee. The Trustee
shall have no responsibility for filing any financing or continuation statement
in any public office at any time or to otherwise perfect or maintain the
perfection of any security interest or lien granted to it hereunder or to
prepare or file any Commission filing for the Trust or to record this Agreement
or any other Basic Document. The Trustee nevertheless agrees that it will, at
its own cost and expense, promptly take all action as may be necessary to
discharge any Liens on any part of the Trust Estate that result from actions by,
or claims against, Chase Manhattan Bank USA, National Association in its
individual capacity or as the Trustee that are not related to the ownership or
the administration of the Trust Estate.

     Section 6.05.  No Action Except Under Specified Documents or Instructions.
The Trustee shall not otherwise deal with any part of the Trust Estate except
(i) in accordance with the powers granted to and the authority conferred upon
the Trustee pursuant to this Agreement, (ii) in accordance with the other Basic
Documents to which it is a party and (iii) in accordance with any document or
instruction delivered to the Trustee pursuant to Section 6.03.

     Section 6.06.  Restrictions. The Trustee shall not take any action (a) that
is inconsistent with the purposes of the Trust set forth in Section 2.03 or (b)
that, to the actual knowledge of the Trustee, would result in the Trust's
becoming taxable as a corporation for Federal income tax purposes. Neither the
Depositor nor the holder of the Excess Distribution Certificate shall direct the
Trustee to take action that would violate the provisions of this Section.

evidenced by or arising under any of the Basic Documents, including the
principal of and interest on the Notes;

or powers vested in it by this Agreement, or to institute, conduct or defend any
litigation under this Agreement or otherwise or in relation to this Agreement,

not specifically prescribed herein, the Trustee may for all purposes hereof rely
on a certificate, signed by the president or any vice president or by the

matter and such certificate shall constitute full protection to the Trustee for
any action taken or omitted to be taken by it in good faith in reliance thereon.

of this Agreement, the Excess Distribution Certificate, or any other Basic
Document (other than the signature of and authentication by the Trustee on the

                               ADDITIONAL TRUSTEES

     Section 10.01. Eligibility Requirements for Trustee. The Trustee shall at
all times (i) be an entity having its principal place of business in the State
of Delaware and otherwise complying with Section 3807 of the Delaware Statutory
Trust Act, (ii) be authorized to exercise statutory trust powers, (iii) have a
combined capital and surplus of at least $50,000,000 and subject to supervision
or examination by Federal or state authorities and (iv) have (or have a parent
which has) a rating in respect of its long-term senior unsecured debt of at
least BBB- (or the equivalent) by each of the Rating Agencies (or which, if the
long-term senior unsecured debt of such entity is not rated by any Rating
Agency, shall have provided to the Indenture Trustee written confirmation from
such Rating Agency that the appointment of such entity to serve as Trustee will
not result in and of itself in a reduction or withdrawal of the then current
rating of any of the Notes). If the Trustee shall publish reports of condition
at least annually, pursuant to law or to the requirements of the aforesaid
supervising or examining authority, then for the purpose of this Section, the
combined capital and surplus of the Trustee 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 10.02.

     Section 10.02. Resignation or Removal of Trustee. The Trustee may at any
time resign and be discharged from the trusts hereby created by giving written
notice thereof to the Administrator. Upon receiving such notice of resignation,
the Administrator shall promptly appoint a successor Trustee meeting the
eligibility requirements of Section 10.01 by written instrument, in duplicate,
one copy of which instrument shall be delivered to the resigning Trustee and one
copy to the successor Trustee. If no successor Trustee shall have been so
appointed and have accepted appointment within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee; provided, however, that
such right to appoint or to petition for the appointment of any such successor
shall in no event relieve the resigning Trustee from any obligations otherwise
imposed on it under the Basic Documents until such successor has in fact assumed
such appointment.

     If at any time the Trustee shall cease to be or shall be likely to cease to
be eligible in accordance with the provisions of Section 10.01 and shall fail to
resign after written request therefor by the Administrator, or if at any time an
Insolvency Event with respect to the Trustee shall have occurred and be
continuing, then the Administrator may remove the Trustee. If the Administrator
shall remove the Trustee under the authority of the immediately preceding
sentence, the Administrator shall promptly appoint a successor Trustee by
written instrument, in duplicate, one copy of which instrument shall be
delivered to the outgoing Trustee so removed and one copy to the successor
Trustee and payment of all fees owed to the outgoing 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 pursuant to
Section 10.03, payment of all fees and expenses owed to the outgoing Trustee and
the filing of a certificate of amendment to the Trust's certificate of trust
pursuant to Section 3810(b) of the Delaware Statutory Trust Act. The

                                       18

<PAGE>

Administrator shall provide notice of such resignation or removal of the Trustee
and to each of the Rating Agencies.

     Section 10.03. Successor Trustee. Any successor Trustee appointed pursuant
to Section 10.02 shall execute, acknowledge and deliver to the Administrator and
to its predecessor Trustee an instrument accepting such appointment under this
Agreement, 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 under this Agreement, with like effect as if
originally named as Trustee. The predecessor Trustee shall upon payment of its
fees and expenses deliver to the successor Trustee all documents, statements,
moneys and properties held by it under this Agreement; and the Administrator and
the predecessor Trustee shall execute and deliver such instruments and do such
other things as may reasonably be required for fully and certainly vesting and
confirming in the successor Trustee all such rights, powers, duties and
obligations.

     No successor Trustee shall accept such appointment as provided in this
Section unless at the time of such acceptance such successor Trustee shall be
eligible pursuant to Section 10.01.

     Upon acceptance of appointment by a successor Trustee pursuant to this
Section, the Administrator shall mail notice of the successor of such Trustee to
the holder of the Excess Distribution Certificate, the Indenture Trustee, the
Noteholders, the Rating Agencies and the Swap Counterparties. If the
Administrator shall fail to mail such notice within 10 days after acceptance of
appointment by the successor Trustee, the successor Trustee shall cause such
notice to be mailed at the expense of the Administrator.

     Section 10.04. Merger or Consolidation of Trustee. Any corporation into
which the Trustee may be merged or converted or with which it may be
consolidated, or any corporation resulting from any merger, conversion or
consolidation to which the Trustee shall be a party, or any corporation
succeeding to all or substantially all the corporate trust business of the
Trustee, shall, without the execution or filing of any instrument or any further
act on the part of any of the parties hereto, anything herein to the contrary
notwithstanding, be the successor of the Trustee hereunder; provided, that such
corporation shall be eligible pursuant to Section 10.01; and provided, further,
that the Trustee shall mail notice of such merger or consolidation to the Rating
Agencies not less than 15 days prior to the effective date thereof.

     Section 10.05. Appointment of Co-Trustee or Separate Trustee.
Notwithstanding any other provisions of this Agreement, at any time, for the
purpose of meeting any legal requirements of any jurisdiction in which any part
of the Trust may at the time be located, the Administrator 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, meeting the
eligibility requirements of clauses (i) through (iii) of Section 10.01, to act
as co-trustee, jointly with the Trustee, or separate trustee or separate
trustees, of all or any part of the Trust Estate, and to vest in such Person, in
such capacity, such title to the Trust Estate, or any part thereof, and, subject
to the other provisions of this Section, such powers, duties, obligations,
rights and trusts as the Administrator and the Trustee may consider necessary or
desirable. If the Administrator shall not have joined in such appointment within
15 days after the receipt by it of a request so to do,

                                       19

<PAGE>

the Trustee alone shall have the power to make such appointment. No co-trustee
or separate trustee under this Agreement shall be required to meet the terms of
eligibility as a successor trustee pursuant to clauses (iv), (v) and (vi) of
Section 10.01 and no notice of the appointment of any co-trustee or separate
trustee shall be required pursuant to Section 10.03.

     Each 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 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, 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
     Trust or any portion thereof in any such jurisdiction) shall be exercised
     and performed singly by such separate trustee or co-trustee, solely at the
     direction of the Trustee;

          (ii)  no trustee under this Agreement shall be personally liable by
     reason of any act or omission of any other trustee under this Agreement;
     and

          (iii) the Administrator 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 Agreement and the conditions
of this Article. 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 Agreement,
specifically including every provision of this Agreement relating to the conduct
of, affecting the liability of, or affording protection to, the Trustee. Each
such instrument shall be filed with the Trustee and a copy thereof given to the
Administrator.

     Any separate trustee or co-trustee may at any time appoint the Trustee as
its agent or attorney-in-fact with full power and authority, to the extent not
prohibited by law, to do any lawful act under or in respect of this Agreement on
its behalf and in its name. If any separate trustee or co-trustee shall die,
become incapable of acting, resign or be removed, all 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.

eliminating any of the provisions in this Agreement or modifying in any manner

affect in any material respect the interests of any Noteholder or the Swap
Counterparties.

the Trustee, with prior written notice to the Rating Agencies, with the consent
of Noteholders evidencing not less than a majority of the Outstanding Amount of

Noteholders.

the Trustee, with prior written notice to the Rating Agencies, with the consent
of the Swap Counterparty or the Cap Counterparty for the purpose of adding any
provisions to, changing in any manner, or eliminating any of the provisions of

Counterparties, respectively.

     Promptly after the execution of any such amendment or consent, the Trustee
shall furnish written notification of the substance of such amendment or consent
to the holder of the Excess Distribution Certificate, the Indenture Trustee, the
Swap Counterparties and each of the Rating Agencies.

     It shall not be necessary for the consent of the Noteholders, the Indenture
Trustee, or the Swap Counterparties pursuant to this Section to approve the
particular form of any proposed amendment or consent, but it shall be sufficient

such consents (and any other consents of provided for in this Agreement or in
