                                [REVERSE OF NOTE]

                  This Note is one of a duly authorized issue of Notes of the
Issuer designated as its __________ Notes (herein called the "Notes"), pursuant
to the terms of a Series Trust Indenture, (the "Indenture") dated as of
__________, consisting of a Series Trust Indenture together with the Standard
Terms and Provisions of Trust Indenture appended thereto together with all other
exhibits, schedules, appendices, supplements and amendments thereto between the
Issuer and ____________________, as Indenture Trustee (herein called the
"Indenture Trustee", which term includes any successor trustee under the
Indenture), pursuant to which this and other Notes have been issued. The
aggregate Principal Balance of the Notes is ___________. Reference is hereby
made to the Indenture and all indentures supplemental thereto for a statement of
the respective rights and obligations thereunder of the Issuer, the Indenture
Trustee and the Noteholders. The Notes are subject to all terms of the
Indenture.

                  All terms used and not otherwise defined in this Note that are
defined in the Indenture, as supplemented or amended, shall have the meanings
assigned to them in or pursuant to the Indenture.

                  All payments made by the Issuer with respect to this Note
shall be applied first to interest due and payable on this Note as provided
above and then to the unpaid principal of this Note.

                  The Notes issued pursuant to the Indenture and will be equally
and ratably secured by the Collateral Obligations pledged as security therefor
as provided in the Indenture.

                  Upon the occurrence of an Event of Default and a declaration
under the Indenture that the Notes are immediately due and payable (i)
Noteholders will be entitled to ratable repayment of principal on the basis of
their respective unpaid Principal Balances and (ii) repayment in full of the
accrued interest on and unpaid Principal Balances of the Notes will be made
prior to any further payment of interest on the Certificates in respect of the
Certificate Principal Balance.

                  Notwithstanding the foregoing, the entire Principal Balance of
this Note shall be due and payable on the date on which an Event of Default
shall have occurred and be continuing and the Indenture Trustee or the
Noteholders representing not less than 25% of the Outstanding Amount of the
Notes have declared the Notes to be immediately due and payable in the manner
provided in Section 5.2 of the Indenture. All payments in respect of the
Principal Balance hereof shall be made pro rata to the Noteholders.

                  [Describe redemption or put option, if any.]

                  [Include provisions relating to foreign currency notes,
indexed notes, multi-currency notes, if any.]

                  Each Noteholder or Note Owner, by acceptance of a Note or, in
the case of a Note Owner, a beneficial interest in a Note, covenants and agrees
that no recourse may be taken, directly or indirectly, with respect to the
obligations of the Issuer, the Owner Trustee or the Indenture Trustee on the
Notes or under the Indenture or any certificate or other writing delivered in
connection therewith, against (i) the Indenture Trustee or the Owner Trustee in
their individual capacities, (ii) any owner of a beneficial interest in the
Issuer or (iii) any partner, owner, beneficiary, agent, officer, director or
employee of the Indenture Trustee or the Owner Trustee in their individual
capacities, any holder of a beneficial interest in the Issuer, the Owner Trustee
or the Indenture Trustee or of any successor or assignee of the Indenture
Trustee or the Owner Trustee in their individual capacities, except as any such
person may have expressly agreed and except that any such partner, owner or
beneficiary shall be fully liable, to the extent provided

                                                                     EXHIBIT 4.6


by applicable law, for any unpaid consideration for stock, unpaid capital
contribution of failure to pay any installment or call owing to such entity.

                  Each Noteholder or Note Owner, by acceptance of a Note or, in
the case of a Note Owner, a beneficial interest in a Note, covenants and agrees
that by accepting the benefits of the Indenture such Noteholder will not, prior
to the date which is one year and one day after the termination of this
Indenture with respect to the Issuer, acquiesce, petition or otherwise invoke or
cause the Depositor or the Issuer to invoke the process of any court or
government authority for the purpose of commencing or sustaining a case against
the Depositor or the Issuer under any federal or state bankruptcy, insolvency or
similar law or appointing a receiver, liquidator, assignee, trustee, custodian,
sequestrator or other similar official of the Depositor or the Issuer or any
substantial part of its property, or ordering the winding up or liquidation of
the affairs of the Depositor or the Issuer.

                  The Indenture permits, with certain exceptions as therein
provided, the amendment thereof and the modification of the rights and
obligations of the Issuer and the rights of the Noteholders under the Indenture
at any time by the Issuer with the consent of Noteholders representing a
majority of the Outstanding Amount of all the Notes. The Indenture also contains
provisions permitting Noteholders representing not less than a majority of the
Outstanding Amount of the Notes, on behalf of all Noteholders, to waive
compliance by the Issuer with certain provisions of the Indenture and certain
past defaults under the Indenture and their consequences. Any such consent or
waiver by the Holder of this Note (or any one of more Predecessor Notes) shall
be conclusive and binding upon such Holder and upon all future Holders of this
Note and of any Note issued upon the registration of transfer hereof or in
exchange hereof or in lieu hereof whether or not notation of such consent or
waiver is made upon this Note. The Indenture also permits the Indenture Trustee
to amend or waive certain terms and conditions set forth in the Indenture
without the consent of the Noteholders.

                  As provided in and subject to the provisions of the Indenture,
the Holder of this Note shall not have the right to institute any proceeding
with respect to the Indenture or for the appointment of a receiver or trustee or
for any other remedy thereunder, unless such Holder shall have previously given
the Indenture Trustee written notice of a continuing Event of Default, the
Holders of not less than 25% of the Outstanding Amounts of the Notes shall have
made written request to the Indenture Trustee to institute proceedings in
respect of such Event of Default as Trustee and offered the Indenture Trustee
reasonable indemnity, and the Trustee shall not have received from the Holders
of a majority of the Outstanding Amount of the Notes a direction inconsistent
with such request, and shall have failed to institute any such proceeding, for
60 days after receipt of such notice, request and offer of indemnity. The
foregoing shall not apply to any suit instituted by the Holder of this Note for
the enforcement of any payment of principal hereof or interest hereon on or
after the respective due dates expressed herein.

                  The Issuer is permitted by the Indenture, under certain
circumstances, to merge or consolidate, subject to the rights of the Indenture
Trustee and the Noteholders under the Indenture.

                  No reference herein to the Indenture and no provisions of this
Note or of the Indenture shall alter or impair the obligation of the Issuer,
which is absolute and unconditional, to pay the principal of and interest on
this Note at the times, place and rate, and in the coin or currency, herein
prescribed.

                  As provided in the Indenture and subject to certain
limitations set forth therein, the transfer of this Note may be registered on
the Note Register upon surrender of this Note for registration of transfer at
the office or agency designated by the Issuer pursuant to the Indenture, duly
endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Indenture Trustee duly executed by, the Holder hereof or
such Holder's attorney duly authorized in writing, with such signature

York City or the city in which the Corporate Trust Office is located, or a
member firm of a national securities exchange, and such other documents as the
Indenture Trustee may require, and thereupon one or more new Notes of authorized
denominations and in the same aggregate Principal Balance will be issued to the
designated transferee or transferees. No service charge will be charged for any
registration of transfer or exchange of this Note, but the transferor may be
required to pay a sum sufficient to cover any tax or other governmental charge
that may be imposed in connection with any such registration of transfer or
exchange.

                  Prior to the due presentment of registration of transfer of
this Note, the Issuer, the Indenture Trustee and any agent of the Issuer of the
Indenture Trustee may treat the Person in whose name this Note (as of the day of
determination or as of such other date as may be specified in the Indenture) is
registered as the owner hereof for all purposes, whether or not this Note shall
be overdue, and neither the Issuer, the Indenture Trustee nor any such agent
shall be affected by notice to the contrary.

                  The Notes are issuable only in registered form without coupons
in denominations of _________ and any integral multiple thereof. As provided in
the Indenture and subject to certain limitations therein set forth, the Notes
are exchangeable for a like aggregate Principal Balance of Notes of a different
authorized denomination, as requested by the Holder surrendering the same.

                  This Note and the Indenture shall be construed in accordance
with the laws of the State of New York, without reference to its conflict of law
provisions (other than Section 5-1401 of the General Obligations Law), and the
obligations, rights and remedies of the parties hereunder and thereunder shall
be determined in accordance with such laws.

                  Anything herein to the contrary notwithstanding, except as
expressly provided in the Basic Documents, neither the Depositor, the Indenture
Trustee nor the Owner Trustee in their respective individual capacities, any
owner of a beneficial interest in the Issuer, nor any of their respective
partners, beneficiaries, agents, officers, directors, employees or successors or
assigns, shall be personally liable for, nor shall recourse be had to any of
them for, the payment of principal of or interest on, or performance of, or
omission to perform, any of the covenants, obligations or indemnifications
contained in this Note or the Indenture, it being expressly understood that said
covenants, obligations and indemnifications have been made by the Owner Trustee
solely as the Owner Trustee in the assets of the Issuer. The Holder of this Note
by the acceptance hereof agrees that, except as expressly provided in the Basic
Documents, in the case of an Event of Default under the Indenture, the Holder
shall have no claim against any of the foregoing for any deficiency, loss or
claim therefrom; provided, however, that nothing contained herein shall be taken
to prevent recourse to, and enforcement against, the assets of the Issuer for
any and all liabilities, obligations and undertakings contained in the Indenture
or in this Note.

                  The principal of and interest of this Note are payable in such
coin or currency of [the United States of America][specify other] [which, at the
time of payment, is legal tender for payment of public and private debts].

                  Unless the certificate of authentication hereon has been
executed by the Indenture Trustee whose name appears below by manual signature,
this Note shall not be entitled to any benefit under the Indenture or be valid
or obligatory for any purpose.

the Issuer and the Indenture Trustee harmless, then, in the absence of notice to

Issuer's request the Indenture Trustee shall authenticate and deliver, in
exchange for or in lieu of any such mutilated, destroyed, lost or stolen Note, a
replacement Note of a like aggregate Principal Balance; provided, however, that
if any such destroyed, lost or stolen Note, but not a mutilated Note, shall have
become or within 7 days shall be due and payable, or shall have been called for
redemption, instead of issuing a replacement Note, the Issuer may pay to the
Holder of such destroyed, lost or stolen Note the amount due and payable thereon

was issued presents for payment such original Note, the Issuer and the Indenture
Trustee shall be entitled to recover such replacement Note (or such payment)

under this Section 2.6, the Issuer may require the payment by the Holder of such
Note of a sum sufficient to cover any tax or other governmental charge that may
be imposed in relation thereto and any other reasonable expenses (including all
fees and expenses of the Indenture Trustee) connected therewith.

                  (d) Any duplicate Note issued pursuant to this Section 2.6 in
replacement for any mutilated, destroyed, lost or stolen Note shall constitute

Trustee and any agent of the Issuer or the Indenture Trustee may treat the
Person in whose name any Note is registered (as of the day of determination) as
the Noteholder for the purpose of receiving payments of principal of and
interest on such Notes and for all other purposes whatsoever, whether or not
such Notes be overdue, and neither the Issuer, the Indenture Trustee nor any
agent of the Issuer or the Indenture Trustee shall be affected by notice to the

                  SECTION 2.8 Payment of Principal and Interest.

in whose name such Note (or one or more Predecessor Notes) is registered on the
applicable Record Date, by check mailed first-class, postage prepaid to such
Person's address as it appears on the Note Register on such Record Date;
provided however, that, unless and until Definitive Notes have been issued
pursuant to Section 2.13, with respect to Notes registered on the applicable
Record Date in the name of the Note Depositary (initially, Cede & Co.), payment
shall be made by wire transfer in immediately available funds to the account
designated by the Note Depositary.

                  (b) The entire unpaid Principal Balance, if any, of the Notes
shall be due and payable, if not previously paid, if

         and

                  (ii) the Indenture Trustee or the Noteholders representing not
         less than 25% of the Outstanding Amount of the Notes have declared the
         Notes to be immediately due and payable in the manner provided in
         Section 5.2.

                  (c) Following an Event of Default and the acceleration of the
Notes as aforesaid, except to the extent otherwise specifically provided herein,
(i) Noteholders will be entitled to ratable repayment of principal on the basis
of their respective unpaid Principal Balances and (ii) repayment in full of the
accrued interest on and unpaid Principal Balances of the Notes will be made
prior to any further payment of interest or principal on the Certificates in
respect of the Certificate Principal Balance.

                  (d) The Indenture Trustee shall notify each Noteholder of
record as of the Record Date for a Distribution Date, of the fact that the final
installment of principal of and interest on such Note is to be paid on such
Distribution Date. Such notice shall be sent (i) on such Record Date by
facsimile, if Book-Entry Notes are outstanding; or (ii) not later than 3
Business Days after such Record Date in accordance with Section 11.5(a), if
Definitive Notes are outstanding, and shall specify that such final installment
shall be payable only upon presentation and surrender of such Note and shall
specify the place where such Note may be presented and surrendered for payment
of such installment. Notices in connection with redemptions of Notes shall be

payment, redemption, exchange or registration of transfer shall, if surrendered

may at any time deliver to the Indenture Trustee for cancellation any Notes
previously authenticated and delivered hereunder which the Issuer may have
acquired in any manner whatsoever, and all Notes so delivered shall be promptly
cancelled by the Indenture Trustee. No Notes shall be authenticated in lieu of
or in exchange for any Notes cancelled as provided in this Section 2.9, except
as expressly permitted by this Indenture. All cancelled Notes may be held or
disposed of by the Indenture Trustee in accordance with its standard retention
or disposal policy as in effect at the time unless the Issuer shall direct by an
Issuer Order that they be destroyed or returned to it; provided, however, that
such Issuer Order is timely and the Notes have not been previously disposed of
by the Indenture Trustee.

                  SECTION 2.10 Release of Collateral Obligations. Subject to
Sections 8.4, 10.3 and 11.1, the Indenture Trustee shall release property from
the Lien of this Indenture, including a release of property pursuant to Section

Certificate, an Opinion of Counsel and Independent Certificates in accordance
with TIA Sections 314(c) and 314(d)(1) or an Opinion of Counsel in lieu of such
Independent Certificates to the effect that the TIA does not require any such
Independent Certificates.

issuance, shall be issued in the form of a typewritten Original Note or Notes
representing the Book-Entry Notes, to be delivered to DTC, the initial Clearing
Agency, by or on behalf of the Issuer. Such Original Note or Notes shall be
registered on the Note Register in the name of the Note Depositary, and no Note
Owner shall receive a Definitive Note representing such Note Owner's interest in
such Note, except as provided in Section 2.13. Unless and until the Definitive
Notes have been issued to Note Owners pursuant to Section 2.13:

                  (a) the provisions of this Section 2.11 shall be in full force
and effect;

                  (b) the Note Registrar and the Indenture Trustee shall be
entitled to deal with the Clearing Agency for all purposes of this Indenture
(including the payment of principal of and interest on the Notes and the giving
of instructions or directions hereunder) as the sole holder of the Notes and
shall have no obligation to the Note Owners;

                  (c) to the extent that the provisions of this Section 2.11
conflict with any other provisions of this Indenture, the provisions of this
Section 2.11 shall control;

                  (d) the rights of the Note Owners shall be exercised only
through the Clearing Agency and shall be limited to those established by law and
agreements between such Note Owners and the Clearing Agency and/or the Clearing
Agency Participants. Unless and until Definitive Notes are issued pursuant to
Section 2.13, the initial Clearing Agency shall make book-entry transfers
between the Clearing Agency Participants and receive and transmit payments of
principal of and interest on the Notes to such Clearing Agency Participants,
pursuant to the Letter of Representations; and

                  (e) whenever this Indenture requires or permits actions to be
taken based upon instructions or directions of Noteholders evidencing a
specified percentage of the Outstanding Amount of the Notes, the Clearing Agency
shall be deemed to represent such percentage only to the extent that it has (i)
received instructions to such effect from Note Owners and/or Clearing Agency
Participants owning or representing respectively, such required percentage of
the beneficial interest in the Notes; and (ii) delivered such instructions to
the Indenture Trustee.

                  SECTION 2.12 Notices to Clearing Agency. Whenever a notice or
other communication to the Noteholders is required under this Indenture, unless
and until Definitive Notes shall have been issued to Note Owners pursuant to
Section 2.13, the Indenture Trustee shall give all such notices and

communications specified herein to be given to Noteholders to the Clearing
Agency and shall have no obligation to the Note Owners.

                  SECTION 2.13 Definitive Notes. If (i) the Depositor advises
the Indenture Trustee in writing that the Clearing Agency is no longer willing
or able to properly discharge its responsibilities with respect to the Notes and
the Issuer is unable to locate a qualified successor; (ii) the Depositor, at its
option, advises the Indenture Trustee in writing that it elects to terminate the
book-entry system through the Clearing Agency; or (iii) after the occurrence of
an Event of Default, Note Owners representing beneficial interests aggregating
at least a majority of the Outstanding Amount of the Notes advise the Clearing
Agency in writing that the continuation of a book-entry system through the
Clearing Agency is no longer in the best interests of the Note Owners, then the
Indenture Trustee shall notify the Clearing Agency of the occurrence of any such
event and of its intent to make definitive dully registered notes ("Definitive
Notes") available to Note Owners, and shall request the surrender to the
Indenture Trustee of the typewritten original Note or Notes representing the
Book-Entry Notes by the Clearing Agency. Upon such surrender, accompanied by
registration instructions from the Clearing Agency, the Issuer shall execute and
the Indenture Trustee shall authenticate the Definitive Notes in accordance with
the instructions of the Clearing Agency. None of the Issuer, the Note Registrar
or the Indenture Trustee shall be liable for any delay in delivery of such
instructions and may conclusively rely on, and shall be protected in relying on,
such instructions. Upon the issuance of Definitive Notes, the Indenture Trustee
shall recognize the Holders of the Definitive Notes as Noteholders.

                  SECTION 2.14 Depositor as Noteholder. Subject to the proviso
set forth in the definition of "Outstanding" in Section 1.1, the Depositor in
its individual or any other capacity may become the owner or pledgee of Notes
and may otherwise deal with the Issuer or its affiliates with the same rights it
would have if it were not the Depositor.

                  SECTION 2.15 Tax Treatment. The Issuer and the Indenture
Trustee, by entering into this Indenture, and the Noteholders, by acquiring any
Notes or interests therein, (i) express their intention that the Note qualify
under applicable tax law as indebtedness secured by the Collateral Obligations,
and (ii) unless otherwise required by appropriate taxing authorities, agree to
treat the Notes as indebtedness secured by the Collateral Obligations for the
purpose of federal income taxes, state and local income and franchise taxes and
any other taxes imposed upon, measured by or based upon gross or net income.

                  SECTION 3.1 Payment of Principal and Interest. The Issuer
shall duly and punctually pay the principal of and interest on the Notes in

Date and on the Redemption Date, the Issuer shall cause all amounts on deposit
in the Collection Account to be distributed in accordance with Section 8.4, less
amounts properly withheld under the Code or applicable state law by any Person
from a payment of interest and/or principal to any Person referred to in Section
8.4. Any amounts so withheld shall be considered as having been paid by the
Issuer to such Noteholder for all purposes of this Indenture.

                  SECTION 3.2 Maintenance of Agency Office. As long as any of
the Notes remains outstanding, the Issuer shall maintain in the Borough of
Manhattan, New York City, an office (the "Agency Office"), being an office or
agency where Notes may be surrendered to the Issuer for registration of transfer
or exchange, and where notices and demands to or upon the Issuer in respect of
the Notes and this Indenture may be served. The Issuer hereby initially appoints
the Indenture Trustee to serve as its agent for the foregoing purposes. The
Issuer shall give prompt written notice to the Indenture Trustee of the
location, and of any change in the location, of any such Agency Office. If at
any time the

Issuer shall fail to maintain any such Agency Office or shall fail to furnish
the Indenture Trustee with the address thereof, such surrenders, notices and
demands may be made or served at the Corporate Trust Office of the Indenture
Trustee, and the Issuer hereby appoints the Indenture Trustee as its agent to
receive all such surrenders, notices and demands.

                  (a) As provided in Section 8.2, all payments of amounts due

behalf of the Issuer by the Indenture Trustee or by another Paying Agent, and no
amounts so withdrawn from the Collection Account for payments of Notes or any
Certificates, Swap Agreement, Related Agreement or Credit Enhancement Agreement
shall be paid over to the Issuer except as provided in this Section 3.3.

                  (b) On or before the Business Day next preceding each
Distribution Date or the Redemption Date, the Issuer shall deposit or cause to
be deposited in the Collection Account (unless such amount has been received
directly by the Indenture Trustee) an aggregate sum sufficient to pay the
amounts then becoming due, such sum to be held in trust for the benefit of the
Persons entitled thereto and (unless the Paying Agent is the Indenture Trustee)
each of the Paying Agent (if such action or failure to act is known to it) and
the Issuer shall promptly notify the Indenture Trustee of the Issuer's action or
failure so to act.

                  (c) The Issuer shall cause each Paying Agent other than the
Indenture Trustee to execute and deliver to the Indenture Trustee an instrument
in which such Paying Agent shall agree with the Indenture Trustee (and if the
Indenture Trustee acts as Paying Agent, it hereby so agrees), subject to the
provisions of this Section 3.3, that such Paying Agent shall:

                  (i) hold all sums held by it for the payment of amounts due
         with respect to the Notes in trust for the benefit of the Persons
         entitled thereto until such sums shall be paid to such Persons or
         otherwise disposed of as herein provided and pay such sums to such
         Persons as herein provided;

                  (ii) give the Indenture Trustee notice of any default by the
         Issuer of which it has actual knowledge (or any other obligor upon the
         Notes) in the making of any payment required to be made with respect to
         the Notes;

                  (iii) at any time during the continuance of any such default,
         upon the written request of the Indenture Trustee, forthwith pay to the
         Indenture Trustee all sums so held in trust by such Paying Agent for
         deposit by the Indenture Trustee in the Collection Account;

                  (iv) immediately resign as a Paying Agent and forthwith pay to
         the Indenture Trustee all sums held by it in trust for the payment of
         Notes if at any time it ceases to meet the standards required to be met
         by a Paying Agent in effect at the time of determination; and

                  (v) comply with all requirements of the Code with respect to
         the withholding from any payments made by it on any Notes of any
         applicable withholding taxes imposed thereon and with respect to any
         applicable reporting requirements in connection therewith.

                  (d) The Issuer may at any time, for the purpose of obtaining
the satisfaction and discharge of this Indenture or for any other purpose, by
Issuer Order direct any Paying Agent to pay to the

Indenture Trustee all sums held in trust by such Paying Agent, such sums to be
held by the Indenture Trustee upon the same trusts as those upon which the sums
were held by such Paying Agent; and upon such payment by any Paying Agent to the
Indenture Trustee, such Paying Agent shall be released from all further
liability with respect to such money.

                  (e) Subject to applicable laws with respect to escheat of
funds, any money held by the Indenture Trustee or any Paying Agent in trust for
the payment of any amount due with respect to any Note and remaining unclaimed
for one year after such amount has become due and payable shall be discharged
from such trust and be paid to the Issuer on Issuer Request; and the Holder of
such Note shall thereafter, as an unsecured general creditor, look only to the
Issuer for payment thereof (but only to the extent of the amounts so paid to the
Issuer), and all liability of the Indenture Trustee or such Paying Agent with
respect to such trust money shall thereupon cease; provided, however, that the
Indenture Trustee or such Paying Agent, before being required to make any such
repayment, may at the expense of the Issuer cause to be published once, in a
newspaper published in the English language, customarily published on each
Business Day and of general circulation in New York City, notice that such money
remains unclaimed and that, after a date specified therein, which shall not be
less than 30 days from the date of such publication, any unclaimed balance of
such money then remaining shall be repaid to the Issuer. The Indenture Trustee
may also adopt and employ, at the expense of the Issuer, any other reasonable
means of notification of such repayment (including, but not limited to, mailing
notice of such repayment to Holders whose Notes have been called but have not
been surrendered for redemption or whose right or interest in moneys due and
payable but not claimed is determinable from the records of the Indenture
Trustee or of any Paying Agent, at the last address of record for each such
Holder).

                  SECTION 3.4 Existence. The Issuer shall keep in full effect
its existence, rights and franchises as a trust under the laws of the State of
its organization (unless it becomes, or any successor Issuer hereunder is or
becomes, organized under the laws of any other State or territory of the United
States of America, in which case the Issuer shall keep in full effect its
existence, rights and franchises under the laws of such other jurisdiction) and
shall obtain and preserve its qualification to do business in each jurisdiction
in which such qualification is or shall be necessary to protect the validity and
enforceability of this Indenture, the Notes, the Collateral Obligations and each
other instrument or agreement included in the Trust Estate.

Pledge. The Issuer shall from time to time execute and deliver all such
supplements and amendments hereto and all such financing statements,
continuation statements, instruments of further assurance and other instruments,
and shall take such other action necessary or advisable to:

                  (i) maintain or preserve the Lien (and the priority thereof)
         of this Indenture or carry out more effectively the purposes hereof;

                  (ii) perfect, publish notice of or protect the validity of any
         Grant made or to be made by this Indenture;

                  (iv) preserve and defend title to the Trust Estate and the
         rights of the Indenture Trustee and the Noteholders in such Trust

                  (a) The Issuer shall not take any action and shall use its
best efforts not to permit any action to be taken by others that would release

expressly provided in this Indenture or such other instrument or agreement.

                  (b) The Issuer may contract with other Persons to assist it in
performing its duties under this Indenture, and any performance of such duties

the Issuer shall be deemed to be action taken by the Issuer.

action by the Issuer in furtherance of any of the foregoing.

The Issuer shall deliver to the Indenture Trustee, within 5 Business Days after
learning of the occurrence thereof, written notice in the form of an Officer's
Certificate of any event which with the giving of notice and the lapse of time
would become an Event of Default under Section 5.1(c), its status and what
action the Issuer is taking or proposes to take with respect thereto.

                  SECTION 5.2 Acceleration of Maturity; Rescission and
Annulment.

                  (a) If an Event of Default, other than an Event of Default as
described in Section 5.1(e) or (f), should occur and be continuing, the
Indenture Trustee or the Holders of Notes representing not less than 25% of the
Outstanding Amount of the Notes may declare all the Notes to be immediately due
and payable, by a notice in writing to the Issuer (and to the Indenture Trustee
if given by the Noteholders) setting forth the Event or Events of Default, and
upon any such declaration the unpaid Principal Balance of such Notes, together
with accrued and unpaid interest thereon through the date of acceleration, shall
become immediately due and payable. If an Event of Default, as described in
Section 5.1(e) or (f), should occur and be continuing, the Indenture Trustee
shall declare all the Notes to be immediately due and payable, and upon any such
declaration the unpaid Principal Balance of such Notes, together with accrued
and unpaid interest thereon through the date of acceleration, shall become
immediately due and payable.

5.1(a), (b), (e) or (f), or any covenant that may only be modified with the
consent of all Noteholders, at any time prior to or after such declaration of
acceleration of maturity has been made and before a judgment or decree for
payment of the money due has been obtained by the Indenture Trustee as
hereinafter provided in this Article V, the Holders of Notes representing a
majority of the Outstanding Amount of the Notes (or if voting rights are
allocated in the Series Trust Indenture other than in accordance with the
Outstanding Amount of the Notes, holders of a majority of those voting rights),
by written notice to the Issuer and the Indenture Trustee, may waive all
Defaults set forth in the notice delivered pursuant to all Defaults set forth in
the notice delivered pursuant to Section 5.2(a), and rescind and annul such
declaration and its consequences; provided, however, that no such rescission and
annulment shall extend to or affect any subsequent default or impair any right
consequent thereto; and provided, further that if the Indenture Trustee shall
have proceeded to enforce any right under this Indenture and such proceedings
shall have been discontinued or abandoned because of such rescission and
annulment or for any other reason, or shall have been determined adversely to
the Indenture Trustee, then and in every such case, the Indenture Trustee, the
Issuer and the Noteholders, as the case may be, shall be restored respectively
to their former positions and rights hereunder, and all rights, remedies and
powers of the Indenture Trustee, the Issuer and the Noteholders, as the case may
be, shall continue as though no such proceedings had been taken.

         the Issuer and the Indenture Trustee of notice thereof from the Holders
         of at least 25% of the Outstanding Amount of the Notes; or

         Trustee or receipt by the Issuer and the Indenture Trustee of notice
         thereof from the holders of at least 25% of the Outstanding Amount of
         the Notes,

the Issuer shall, upon demand of the Indenture Trustee, pay to the Indenture
Trustee, for the ratable benefit of the Noteholders in accordance with their
respective outstanding Principal Balances, the whole amount then due and payable
on such Notes for principal and interest, with interest upon the overdue
principal, at the rate borne by the Notes and in addition thereto such further
amount as shall be sufficient to cover the costs and expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of
the Indenture Trustee and its agents and counsel.

                  (b) If the Issuer shall fail forthwith to pay such amounts
upon such demand, the Indenture Trustee, in its own name and as trustee of an
express trust, may institute a Proceeding for the collection of the sums so due
and unpaid, and may prosecute such Proceeding to judgment or final decree, and
may enforce the same against the Issuer or other obligor upon such Notes and
collect in the manner provided by law out of the property of the Issuer or other
obligor upon such Notes, wherever situated, the moneys adjudged or decreed to be
payable.

                  (c) If an Event of Default occurs and is continuing, the
Indenture Trustee may, as more particularly provided in Section 5.4, in its
discretion, proceed to protect and enforce its rights and the rights of the
Noteholders, by such appropriate Proceedings as the Indenture Trustee shall deem
most effective to protect and enforce any such rights, whether for the specific
enforcement of any covenant or agreement in this Indenture or in aid of the
exercise of any power granted herein, or to enforce any other proper remedy or
legal or equitable right vested in the Indenture Trustee by this Indenture or by
law.

                  (d) If there shall be pending, relative to the Issuer or any
other obligor upon the Notes or any Person having or claiming an ownership
interest in the Trust Estate, proceedings under Title 11 of the United States
Code or any other applicable federal or state bankruptcy, insolvency or other
similar law, or if a receiver, assignee or trustee in bankruptcy or
reorganization, liquidator, sequestrator or similar official shall have been
appointed for or taken possession of the Issuer or its property or such other
obligor or Person, or in case of any other comparable judicial Proceedings
relative to the Issuer or other obligor upon the Notes, or to the creditors or
property of the Issuer or such other obligor, the Indenture Trustee,
irrespective of whether the principal of any Notes shall then be due and payable
as therein expressed or by declaration or otherwise and irrespective of whether
the Indenture Trustee shall have made any demand pursuant to the provisions of
this Section 5.3, shall be entitled and empowered, by intervention in such
Proceedings or otherwise:

                  (i) to file and prove a claim or claims for the whole amount
         of principal and interest owing and unpaid in respect of the Notes and
         to file such other papers or documents as may be necessary or advisable
         in order to have the claims of the Indenture Trustee (including any
         claim for reasonable compensation to the Indenture Trustee and each
         predecessor Trustee, and their respective agents, attorneys and
         counsel, and for reimbursement of all expenses and liabilities
         incurred, and all advances made, by the Indenture Trustee and each
         predecessor Trustee, except as a result of negligence or bad faith) and
         of the Noteholders allowed in such Proceedings;

                  (ii) unless prohibited by applicable law and regulations to
         vote on behalf of the Holders of Notes in any election of a trustee, a
         standby trustee or Person performing similar functions in any such
         Proceedings;

                  (iii) to collect and receive any moneys or other property
         payable or deliverable on any such claims and to distribute all amounts
         received with respect to the claims of the Noteholders and of the
         Indenture Trustee on their behalf; and

                  (iv) to file such proofs of claim and other papers or
         documents as may be necessary or advisable in order to have the claims
         of the Indenture Trustee or the Holders of Notes allowed in any
         judicial proceedings relative to the Issuer, its creditors and its
         property;

and any trustee, receiver, liquidator, custodian or other similar official in
any such Proceeding is hereby authorized by each of such Noteholders to make
payments to the Indenture Trustee, and, if the Indenture Trustee shall consent
to the making of payments directly to such Noteholders, to pay to the Indenture
Trustee such amounts as shall be sufficient to cover reasonable compensation to
the Indenture Trustee, each predecessor trustee and their respective agents,
attorneys and counsel, and all other expenses and liabilities incurred, and all
advances made by the Indenture Trustee and each predecessor trustee except as a
result of negligence or bad faith.

                  (e) Nothing herein contained shall be deemed to authorize the
Indenture Trustee to authorize or consent to or vote for or accept or adopt on
behalf of any Noteholder any plan of reorganization, rearrangement, adjustment
or composition affecting the Note or the rights of any Holder thereof or to
authorize the Indenture Trustee to vote in respect of the claim of any
Noteholder in any such proceeding except, as aforesaid, to vote for the election
of a trustee in bankruptcy or similar Person.

                  (f) All rights of action and of asserting claims under this
Indenture, or under any of the Notes, may be enforced by the Indenture Trustee
without the possession of any of the Notes or the production thereof in any
trial or other Proceedings relative thereto, and any such Proceedings instituted
by the Indenture Trustee shall be brought in its own name as trustee of an
express trust, and any recovery of judgment, subject to the payment of the
expenses, disbursements and compensation of the Indenture Trustee, each
predecessor trustee and their respective agents and attorneys, shall be for the
ratable benefit of the Noteholders.

                  (g) In any Proceedings brought by the Indenture Trustee (and
also any Proceedings involving the interpretation of any provision of this
Indenture to which the Indenture Trustee shall be a party), the Indenture
Trustee shall be held to represent all the Noteholders, and it shall not be
necessary to make any Noteholder a party to any such Proceedings.

                  SECTION 5.4 Remedies; Priorities.

                  (a) If an Event of Default shall have occurred and be
continuing, the Indenture Trustee may do one or more of the following (subject
to Section 5.5):

                  (i) institute Proceedings in its own name and as trustee of an
         express trust for the collection of all amounts then payable on the
         Notes or under this Indenture with respect thereto, whether by
         declaration or otherwise, enforce any judgment obtained, and collect
         from the Issuer and any other obligor upon such Notes moneys adjudged
         due;

                  (ii) institute Proceedings from time to time for the complete
         or partial foreclosure of this Indenture with respect to the Trust
         Estate;

                  (iii) exercise any remedies of a secured party under the UCC
         and take any other appropriate action to protect and enforce the rights
         and remedies of the Indenture Trustee and the Noteholders; and

                  (iv) sell the Trust Estate or any portion thereof or rights or
         interest therein, at one or more public or private sales called and
         conducted in any manner permitted by law; provided, however, that the
         Indenture Trustee may not sell or otherwise liquidate the Trust Estate
         following an Event of Default, unless (A) the Holders of all of the
         Outstanding Amount of the Notes consent thereto, (B) the proceeds of
         such sale or liquidation distributable to the Noteholders are
         sufficient to discharge in full the principal of and the accrued
         interest on the Notes at the date of such sales or liquidation and the
         Holders of 66 2/3% of the Outstanding Amount of the Notes consent
         thereto or (C) the Indenture Trustee determines that the Trust Estate
         will not continue to provide sufficient funds for the payment of
         principal of and interest on the Notes as they would have become due if
         the Notes had not been declared due and payable, and the Indenture
         Trustee obtains the consent of Holders of 66 2/3% of the Outstanding
         Amount of the Notes. In determining such sufficiency or insufficiency
         with respect to clauses (B) and (C), the Indenture Trustee may, but
         need not, obtain and rely upon an opinion of an independent investment
         banking or accounting firm of national reputation as to the sufficiency
         of the Trust Estate for such purpose.

                  (b) If the Indenture Trustee collects any money or property
pursuant to this Article V, it shall pay out the money or property in the
following order:

                  FIRST: to the Indenture Trustee for amounts due under Section
         6.7;

                  SECOND: to Noteholders for amounts due and unpaid on the Notes
         for interest and principal, ratably among all classes of Noteholders,
         according to the amounts due and payable on such Notes for interest
         and/or principal; and

                  THIRD: to the Owner Trustee for amounts required to be
         distributed to the Certificateholders pursuant to the Trust Agreement.

                  The Indenture Trustee may fix a record date and distribution
date for any payment to Noteholders pursuant to this Section 5.4. At least 15
days before such record date, the Issuer shall mail to each Noteholder and the
Indenture Trustee a notice that states the record date, the distribution date
and the amount to be paid.

                  SECTION 5.5 Optional Preservation of the Collateral
Obligations. If the Notes have been declared to be due and payable under Section
5.2 following an Event of Default and such declaration and its consequences have
not been rescinded and annulled, the Indenture Trustee may, but need not, elect
to take and maintain possession of the Trust Estate. It is the desire of the
parties hereto and the Noteholders that there be at all times sufficient funds
for the payment of principal of and interest on the Notes, and the Indenture
Trustee shall take such desire into account when determining whether or not to
take and maintain possession of the Trust Estate. In determining whether or not
to take and maintain possession of the Trust Estate, the Indenture Trustee may,
but need not obtain and rely upon an opinion of an independent investment
banking or accounting firm of national reputation as to the feasibility of such
proposed action and as to the sufficiency of the Trust Estate for such purpose.

                  SECTION 5.6 Limitation of Suits. No Holder of any Note shall
have any right to institute any Proceeding, judicial or otherwise, with respect
to this Indenture, or for the appointment of a receiver or trustee, or for any
other remedy hereunder, unless:

                  (i) such Holder has previously given written notice to the
         Indenture Trustee of a continuing Event of Default;

                                                                     EXHIBIT 4.6


                  (ii) the Holders of not less than 25% of the Outstanding
         Principal Balance of the Notes have made written request to the
         Indenture Trustee to institute such Proceeding in respect of such Event
         of Default in its own name as Indenture Trustee hereunder;

                  (iii) such Holder or Holders have offered to the Indenture
         Trustee reasonable indemnity against the costs, expenses and
         liabilities to be incurred in complying with such request;

                  (iv) the Indenture Trustee for 60 days after its receipt of
         such notice, request and offer of indemnity has failed to institute
         such Proceedings; and

                  (v) no direction inconsistent with such written request has
         been given to the Indenture Trustee during such 60-day period by the
         Holders of a majority of the Outstanding Amount of the Notes;

it being understood and intended that no one or more Holders of Notes shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other
Holders of Notes or to obtain or to seek to obtain priority or preference over
any other Holders of Notes or to enforce any right under this Indenture, except
in the manner herein provided and for the equal, ratable and common benefit of
all holders of Notes. For the protection and enforcement of the provisions of
this Section 5.6, each and every Noteholder shall be entitled to such relief as
can be given either at law or in equity.

                  If the Indenture Trustee shall receive conflicting or
inconsistent requests and indemnity from two or more groups of Holders of Notes,
each representing less than a majority of the Outstanding Amount of the Notes,
the Indenture Trustee in its sole discretion may determine what action, if any,
shall be taken, notwithstanding any other provisions of this Indenture.

                  SECTION 5.7 Unconditional Rights of Noteholders to Receive
Principal and Interest. Notwithstanding any other provisions in this Indenture,
the Holder of any Note shall have the right, which is absolute and
unconditional, to receive payment of the Principal Balance, if any, of and
interest on such Note on or after the respective due dates thereof expressed in
such Note or in this Indenture (or, in the case of redemption, on or after the
Redemption Date) and to institute suit for the enforcement of any such payment
on or after the date such payment is payable, and such right shall not be
impaired without the consent of such Holder; provided that the right to
institute such a suit shall be denied if and to the extent that the institution
or prosecution thereof or the entry of judgment therein would, under applicable
law, result in the surrender, impairment, waiver or loss of the Lien of this
Indenture upon any property subject to such Lien.

                  SECTION 5.8 Restoration of Rights and Remedies. If the
Indenture Trustee or any Noteholder has instituted any Proceeding to enforce any
right or remedy under this Indenture and such Proceeding has been discontinued
or abandoned for any reason or has been determined adversely to the Indenture
Trustee or to such Noteholder, then and in every such case the Issuer, the
Indenture Trustee and the Noteholders shall, subject to any determination in
such Proceeding, be restored severally and respectively to their former
positions hereunder, and thereafter all rights and remedies of the Indenture
Trustee and the Noteholders shall continue as though no such Proceeding had been
instituted.

                  SECTION 5.9 Rights and Remedies Cumulative. No right or remedy
herein conferred upon or reserved to the Indenture Trustee or to the Noteholders
is intended to be exclusive of any other right or remedy, and every right and
remedy shall, to the extent permitted by law, be cumulative and in addition to
every other right and remedy given hereunder or now or hereafter existing at law
or in equity

or otherwise. The assertion or employment of any right or remedy hereunder, or
otherwise, shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.

                  SECTION 5.10 Delay or Omission Not a Waiver. No delay or
omission of the Indenture Trustee of any Holder of any Note to exercise any
right or remedy accruing upon any Default or Event of Default shall impair any
such right or remedy or constitute a waiver of any such Default or Event of
Default or an acquiescence therein. Every right and remedy given by this Article
V or by law to the Indenture Trustee or to the Noteholders may be exercised from
time to time, and as often as may be deemed expedient, by the Indenture Trustee
or by the Noteholders, as the case may be.

                  SECTION 5.11 Control by Noteholders. The Holders of a majority
of the Outstanding Amount of the Notes shall, subject to provisions being made
for indemnification against costs, expenses and liabilities in a form
satisfactory to the Indenture Trustee, have the right to direct the time, method
and place of conducting any Proceeding for any remedy available to the Indenture
Trustee with respect to the Notes or exercising any trust or power conferred on
the Indenture Trustee; provided, however, that:

                  (i) such direction shall not be in conflict with any rule of
         law or with this Indenture;

                  (ii) subject to the express terms of Section 5.4, any
         direction to the Indenture Trustee to sell or liquidate the Trust
         Estate shall be by the Holders of Notes representing not less than 100%
         of the Outstanding Amount of the Notes;

                  (iii) if the conditions set forth in Section 5.5 have been
         satisfied and the Indenture Trustee elects to retain the Trust Estate
         pursuant to Section 5.5, then any direction to the Indenture Trustee by
         Holders of Notes representing less than 100% of the Outstanding Amount
         of the Notes to sell or liquidate the Trust Estate shall be of no force
         and effect; and

                  (iv) the Indenture Trustee may take any other action deemed
         proper by the Indenture Trustee that is not inconsistent with such
         direction;

provided, however, that, subject to Section 6.1, the Indenture Trustee need not
take any action that it determines might cause it to incur any liability or
might materially adversely affect the rights of any Noteholders not consenting
to such action. The Indenture Trustee shall obtain instructions from the
Noteholders in connection with any vote, consent or waiver in relation to which
it is entitled to vote in respect of any asset forming part of the Trust Estate.
The Indenture Trustee shall direct any action or cast any vote as the holder of
such asset in proportion to the aggregate outstanding Principal Balance of Notes
held by Noteholders that take the corresponding position.

                  SECTION 5.12 Waiver of Past Defaults.

                  (a) Prior to the declaration of the acceleration of the
maturity of the Notes as provided in Section 5.2, the Holders of not less than a
majority of the Outstanding Amount of the Notes may waive any past Default or
Event of Default and its consequences except a Default (i) in the payment of
principal of or interest on any of the Notes or (ii) in respect of a covenant or
provision hereof which cannot be modified or amended without the consent of the
Holder of each Note. In the case of any such waiver, the Issuer, the Indenture
Trustee and the Noteholders shall be restored to their former positions and
rights hereunder, respectively; but no such waiver shall extend to any
subsequent or other Default or impair any right consequent thereto.

                  (b) Upon any such waiver, such Default shall cease to exist
and be deemed to have been cured and not to have occurred, and any Event of
Default arising therefrom shall be deemed to have

been cured and not have occurred, for every purpose of this Indenture; but no
such waiver shall extend to any subsequent or other Default or Event of Default
or impair any right consequent thereto.

                  SECTION 5.13 Undertaking for Costs. All parties to this
Indenture agree, and each Holder of any Note by such Holder's acceptance thereof
shall be deemed to have agreed, that any court may in its discretion require, in
any proceeding for the enforcement of any right or remedy under this Indenture,
or in any Proceeding against the Indenture Trustee for any action taken,
suffered or omitted by it as Indenture Trustee, the filing by any party litigant
in such Proceeding of an undertaking to pay the costs of such proceeding and
that such court may in its discretion assess reasonable costs, including
reasonable attorneys' fees, against any party litigant in such Proceeding,
having due regard to the merits and good faith of the claims or defenses made by
such party litigant; but the provisions of this Section 5.13 shall not apply to:

                  (a) any Proceeding instituted by the Indenture Trustee;

                  (b) any Proceeding instituted by any Noteholder, or group of
Noteholders, in each case holding in the aggregate more than 10% of the
Outstanding Amount of the Notes; or

                  (c) any Proceeding instituted by any Noteholder for the
enforcement or the payment of principal of or interest on any Note on or after
the respective due dates expressed in such Note and in this Indenture (or, in
the case of redemption, on or after the Redemption Date).

                  SECTION 5.14 Waiver of Stay or Extension Laws. The Issuer
covenants (to the extent that it may lawfully do so) that it shall not at any
time insist upon, or plead or in any manner whatsoever, claim or take the
benefit or advantage of, any stay or extension law wherever enacted, now or at
any time hereafter in force, that may affect the covenants or the performance of
this Indenture. The Issuer (to the extent that it may lawfully do so) hereby
expressly waives all benefit or advantage of any such law, and covenants that it
shall not hinder, delay or impede the execution of any power herein granted to
the Indenture Trustee, but shall suffer and permit the execution of every such
power as though no such law had been enacted.

                  SECTION 5.15 Action on Notes. The Indenture Trustee's right to
seek and recover judgment on the Notes or under this Indenture shall not be
affected by the seeking, obtaining or application of any other relief under or
with respect to this Indenture. Neither the Lien of this Indenture nor any
rights or remedies of the Indenture Trustee or the Noteholders shall be impaired
by the recovery of any judgment by the Indenture Trustee against the Issuer or
by the levy of any execution under such judgment upon any portion of the Trust
Estate or upon any of the assets of the Issuer.

                  SECTION 5.16 Performance and Enforcement of Certain Collateral
Obligations.

                  (a) Promptly following a request from the Indenture Trustee to
do so, the Issuer agrees to take all such lawful action as the Indenture Trustee
may request to compel or secure the performance and observance by the Depositor
and the obligors on the Collateral Obligations of its and their obligations,
respectively, to the Issuer under or in connection with the Trust Agreement, in
accordance with the terms thereof, and to exercise any and all rights, remedies,
powers and privileges lawfully available to the Issuer under or in connection
with the Trust Agreement to the extent and in the manner directed by the
Indenture Trustee, including the transmission of notices of default on the part
of the Depositor and the obligors on the Collateral Obligations thereunder and
the institution of legal or administrative actions or proceedings to compel or
secure performance by the Depositor and the obligors on the Collateral
Obligations on its or their obligations, respectively, under the Trust
Agreement.

                  (b) If an Event of Default has occurred and is continuing, the
Indenture Trustee may, and, at the direction (which direction shall be in
writing or by telephone (confirmed in writing promptly thereafter)) of the
Holders of 66 2/3% of the Outstanding Amount of the Notes shall, exercise all
rights, remedies, powers, privileges and claims of the Issuer against the
Depositor under or in connection with the Trust Agreement, including the right
or power to take any action to compel or secure performance or observance by the
Depositor of its obligations to the Issuer thereunder and to give any consent,
request, notice, direction, approval, extension or waiver under the Trust
Agreement, and any right of the Issuer to take such action shall be suspended.

                              THE INDENTURE TRUSTEE

                  SECTION 6.1 Duties of Indenture Trustee.

                  (a) If an Event of Default has occurred and is continuing, the
Indenture Trustee shall exercise the rights and powers vested in it by this
Indenture, and shall use the same degree of care and skill in their exercise, as
a prudent person would exercise or use under the circumstances in the conduct of
such person's own affairs.

                  (b) Except during the continuance of an Event of Default:

                  (i) the Indenture Trustee shall not be liable expect for the
         performance of such duties and only such duties as are specifically set
         forth in this Indenture and no implied covenants or obligations shall
         be read into this Indenture against the Indenture Trustee, and

                  (ii) in the absence of bad faith on its part, the Indenture
         Trustee may conclusively rely, as to the truth of the statements and
         correctness of the opinions expressed therein, upon certificates or
         opinions furnished to the Indenture Trustee and conforming to the
         requirements of this Indenture; provided, however, that the Indenture
         Trustee shall examine the certificates and opinions to determine
         whether or not they conform to the requirements of this Indenture.

                  (c) The Indenture Trustee may not be relieved from liability
for its own negligent action, its own negligent failure to act or its own
willful misconduct, except that:

                  (i) this Section 6.1(c) does not limit the effect of Section
         6.1(b);

                  (ii) the Indenture Trustee shall not be liable for any error
         of judgment made in good faith by a Responsible Officer or Officers
         unless it is proved that the Indenture Trustee was negligent in
         ascertaining the pertinent facts; and

                  (iii) the Indenture Trustee shall not be liable with respect
         to any action it takes or omits to take in good faith in accordance
         with a direction received by it pursuant to Section 5.11 or Section
         6.16.

                  (d) The Indenture Trustee shall not be liable for interest on
any money received by it except as the Indenture Trustee may agree in writing
with the Issuer.

                  (e) No provision of this Indenture shall require the Indenture
Trustee to expend or risk its own funds or otherwise incur financial liability
in the performance of any of its duties hereunder or in the exercise of any of
its rights or powers if it shall have reasonable grounds to believe that

repayments of such funds or adequate indemnity against such risk or liability is
not reasonably assured to it.

                  (f) Every provision of this Indenture relating to the
Indenture Trustee shall be subject to the provisions of this Section 6.1 and to
the provisions of the TIA.

                  (g) Notwithstanding anything to the contrary contained herein
or in the Series Trust Indenture, the Indenture Trustee shall not be an
Affiliate of the Owner Trustee.

                  SECTION 6.2 Rights of Indenture Trustee.

                  (a) The Indenture Trustee may rely on any document believed by
it to be genuine and to have been signed or presented by the proper person. The
Indenture Trustee need not investigate any fact or matter stated in the
documents.

                  (b) Before the Indenture Trustee acts or refrains from acting,
it may require an Officer's Certificate, Independent Certificate or an Opinion
of Counsel. The Indenture Trustee shall not be liable for any action it takes or
omits to take in good faith in reliance on the Officer's Certificate,
Independent Certificate or Opinion of Counsel.

                  (c) The Indenture Trustee may execute any of the trusts or
powers thereunder or perform any duties hereunder either directly or by or
through agents or attorneys or a custodian or nominee, and the Indenture Trustee
shall not be responsible for any misconduct or negligence on the part of, or for
the supervision of, any such agent, attorney, custodian or nominee appointed
with due care by it hereunder.

                  (d) The Indenture Trustee shall not be liable for any action
it takes or omits to take in good faith which it believes to be authorized or
within its rights or powers; provided, however, that the Indenture Trustee's
conduct does not constitute willful misconduct, negligence or bad faith.

                  (e) The Indenture Trustee may consult with counsel, and the
advice or opinion of counsel with respect to legal matters relating to this
Indenture and the Notes shall be full and complete authorization and protection
from liability in respect to any action taken, omitted or suffered by it
hereunder in good faith and in accordance with the advice or opinion of such
counsel.

                  SECTION 6.3 Indenture Trustee May Own Notes. The Indenture
Trustee in its individual or any other capacity may become the owner or pledgee
of Notes and may otherwise deal with the Issuer or any of its respective
Affiliates with the same rights it would have if it were not Indenture Trustee;
provided, however, that the Indenture Trustee shall comply with Sections 6.10
and 6.11. Any Paying Agent, Note Registrar, co-registrar or co-paying agent may
do the same with like rights.

                  SECTION 6.4 Indenture Trustee's Disclaimer. The Indenture
Trustee shall not be responsible for and makes no representations as to the
validity or adequacy of this Indenture or the Notes, it shall not be accountable
for the Issuer's use of the proceeds from the Notes, and it shall not be
responsible for any statement of the Issuer in the Indenture or in any document
issued in connection with the sale of the Notes or in the Notes other than the
Indenture Trustee's certificate or authentication.

                  SECTION 6.5 Notice of Defaults. If a Default occurs and is
continuing and if it is known to a Responsible Officer of the Indenture Trustee,
the Indenture Trustee shall mail to the Rating Agency and each Noteholder notice
of the Default, as required by TIA Section 313(c), within 90 days after such
Default occurs. Except in the case of a Default in payment of principal of or
interest on any

Note (including payments pursuant to the mandatory redemption provisions of such
Note), the Indenture Trustee may withhold the notice to Noteholders if and so
long as a committee of its Responsible Officers in good faith determines that
withholding the notice is in the interests of Noteholders.

                  SECTION 6.6 Reports by Indenture Trustee.

                  (a) The Indenture Trustee shall deliver to each Noteholder the
information and documents set forth in Article VII, and, in addition, all such
information with respect to the Notes as may be required to enable such Holder
to prepare its federal and state income tax returns.

                  (b) On each Distribution Date, the Indenture Trustee shall
prepare a report setting forth the following information with respect to the
Interest Accrual Period ending on such Distribution Date: (i) the amount of
moneys credited to the Collection Account; (ii) the amount of moneys paid to the
Noteholders, Certificateholders, the counterparty to any Swap Agreement, the
other parties to any Related Agreement or the other parties to any Credit
Enhancement Agreement, and any other related information that may be relevant to
the Noteholders or specified in the Series Trust Indenture; and (v) the amount
of moneys distributed to the Certificateholders and any other related
information that may be relevant to the Noteholders or specified in the Series
Trust Indenture. Copies of this report shall be delivered to the Owner Trustee
and to the Depositor.

                  SECTION 6.7 Compensation; Indemnity.

                  (a) The Indenture Trustee shall receive as compensation for
its services hereunder such fees as have been separately agreed upon before the
date hereof between the Depositor and the Indenture Trustee and the Indenture
Trustee hereby acknowledges that such fees have been paid. The Indenture
Trustee's compensation shall not be limited by any law on compensation of a
trustee of an express trust. The Issuer shall reimburse or cause to be
reimbursed the Indenture Trustee for all reasonable out-of-pocket expenses
incurred or made by it, including costs of collection. In addition to the
compensation for its services, such expenses shall include the reasonable
compensation and expenses, disbursements and advances of the Indenture Trustee's
agents, counsel, accountants and experts. The Issuer shall indemnify the
Indenture Trustee against any and all loss, liability or expense (including
attorney's fees) incurred by it in connection with the administration of this
trust and the performance of its duties hereunder. The Indenture Trustee shall
notify the Issuer promptly of any claim for which it may seek indemnity. Failure
by the Indenture Trustee to so notify the Issuer shall not relieve the Issuer of
its obligations hereunder. The Issuer shall defend the claim and the Indenture
Trustee may have separate counsel and the Issuer shall pay the fees and expenses
of such counsel. The Issuer need not reimburse any expense or indemnity against
any loss, liability or expense incurred by the Indenture Trustee through the
Indenture Trustee's own willful misconduct, negligence or bad faith.

                  (b) The Issuer's payment obligations to the Indenture Trustee
pursuant to this Section 6.7 shall survive the discharge of this Indenture. When
the Indenture Trustee incurs expenses after the occurrence of a Default
specified in Section 5.1(e) or (f) with respect to the Issuer, the expenses are
intended to constitute expenses of administration under Title 11 of the United
States Code or any other applicable federal or state bankruptcy, insolvency or
similar law.

                  (c) The Issuer's payment obligations to the Indenture Trustee
pursuant to this Section 6.7 shall be satisfied to the extent that funds are
available to make such payments after all amounts payable to Noteholders and
Certificateholders pursuant to this Indenture and the Trust Agreement shall have
been paid, unless otherwise specified in the Series Trust Indenture, and there
shall be no recourse to the Issuer for all or any part of any amounts payable
pursuant to this Section 6.7 if such funds are at any time insufficient to make
all or part of any such payments.

                  SECTION 6.8 Replacement of Indenture Trustee.

                  (a) The Indenture Trustee may resign at any time by so
notifying the Issuer. The Holders of a majority in Outstanding Amount of the
Notes may remove the Indenture Trustee by so notifying the Indenture Trustee and
may appoint a successor Indenture Trustee. Such resignation or removal shall
become effective in accordance with Section 6.8(c). The Issuer shall remove the
Indenture Trustee if:

                           (1) the Indenture Trustee fails to comply with
                  Section 6.11;

                           (2) the Indenture Trustee is adjudged a bankrupt or
                  insolvent;

                           (3) the Indenture Trustee is or becomes an Affiliate
                  of the Owner Trustee;

                           (4) a receiver or other public officer takes charge
                  of the Indenture Trustee or its property; or

                           (5) the Indenture Trustee otherwise becomes incapable
                  of acting.

                  (b) If the Indenture Trustee resigns or is removed or if a
vacancy exists in the office of Indenture Trustee for any reason (the Indenture
Trustee in such event being referred to herein as the "retiring Indenture
Trustee"), the Issuer shall promptly appoint a successor Indenture Trustee.

                  (c) A successor Indenture Trustee shall deliver a written
acceptance of its appointment to the retiring Indenture Trustee and to the
Issuer. Thereupon the resignation or removal of the retiring Indenture Trustee
shall become effective, and the successor Indenture Trustee shall have all the
rights, powers and duties of the Indenture Trustee under this Indenture. The
successor Indenture Trustee shall mail a notice of its succession to
Noteholders. The retiring Indenture Trustee shall promptly transfer all property
held by it as Indenture Trustee to the successor Indenture Trustee.

                  (d) If a successor Indenture Trustee does not take office
within 60 days after the retiring Indenture Trustee resigns or is removed, the
retiring Indenture Trustee, the Issuer or the Holders of a majority of the
Outstanding Amount of the Notes may petition any court of competent jurisdiction
for the appointment of a successor Indenture Trustee.

                  (e) If the Indenture Trustee fails to comply with Section
6.11, any Noteholder may petition any court of competent jurisdiction for the
removal of the Indenture Trustee and the appointment of a successor Indenture
Trustee.

                  (f) Notwithstanding the replacement of the Indenture Trustee
pursuant to this Section 6.8, the Issuer's and the Depositor's obligations under
Section 6.7 shall continue for the benefit of the retiring Indenture Trustee.

                  SECTION 6.9 Merger or Consolidation of Indenture Trustee.

                  (a) Any corporation into which the Indenture Trustee may be
merged or with which it may be consolidated, or any corporation resulting from
any merger or consolidation to which the Indenture Trustee shall be a party, or
any corporation succeeding to the corporate trust business or the Indenture
Trustee, shall be the successor of the Indenture Trustee under this Indenture;
provided, however, that such corporation shall be eligible under the provisions
of Section 6.11, without the

execution or filing of any instrument or any further act on the part of any of
the parties to this Indenture, anything in this Indenture to the contrary
notwithstanding.

                  (b) If at any time such successor or successors by merger or
consolidation to the Indenture Trustee shall succeed to the trusts created by
this Indenture any of the Notes shall have been authenticated but not delivered,
any such successor to the Indenture Trustee may adopt the certificate of
authentication of any predecessor trustee, and deliver such Notes so
authenticated; and in case at that time any of the Notes shall not have been
authenticated, any successor to the Indenture Trustee may authenticate such
Notes either in the name of any predecessor hereunder or in the name of the
successor to the Indenture Trustee. In all such cases such certificate of
authentication shall have the same full force as is provided anywhere in the
Notes or herein with respect to the certificate of authentication of the
Indenture Trustee.

                  SECTION 6.10 Appointment of Co-Indenture Trustee or Separate
Indenture Trustee.

                  (a) Notwithstanding any other provision of this Indenture, at
any time, for the purpose of meeting any legal requirement of any jurisdiction
in which any part of the Issuer may at the time be located, the Indenture
Trustee shall have the power and may execute and deliver all instruments to
appoint one or more Persons to act as co-trustee, jointly with the Indenture
Trustee, or as separate trustee or trustees, of all or any part of the Issuer,
and to vest in such Person or Persons in such capacity and for the benefit of
the Noteholders, such title to the Trust Estate, or any part thereof, and,
subject to the other provisions of this Section 6.10, such powers, duties,
obligations, rights and trusts as the Indenture Trustee may consider necessary
or desirable. No co-trustee or separate trustee hereunder shall be required to
meet the terms of eligibility as a successor trustee under Section 6.11 and no
notice to Noteholders of the appointment of any co-trustee or separate trustee
shall be required under Section 6.8.

                  (b) 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 Indenture Trustee shall be conferred or imposed upon
         and exercised or performed by the Indenture 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
         Indenture 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 Indenture 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 Estate 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 Indenture Trustee;

                  (ii) no separate trustee or co-trustee hereunder shall be
         personally liable by reason of any act or omission of any other trustee
         hereunder; and

                  (iii) the Indenture Trustee may at any time accept the
         resignation of or remove any separate trustee or co-trustee.

                  (c) Any notice, request or other writing given to the
Indenture 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 Indenture and the conditions of this Article VI. 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 Indenture Trustee or separately, as may be
provided therein, subject to all the provisions of this Indenture, specifically
including every provision of this Indenture relating to the conduct of,
affecting the liability of, or affording protection to, the Indenture Trustee.
Each such instrument shall be filed with the Indenture Trustee.

                  (d) Any separate trustee or co-trustee may at any time appoint
the Indenture 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 Indenture 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 Indenture Trustee, to the extent permitted by law, without the
appointment of a new or successor trustee.

                  SECTION 6.11 Eligibility; Disqualification. The Indenture
Trustee shall at all times satisfy the requirements of TIA Section 310(a). The
Indenture Trustee shall at all times be a bank, trust company or corporation
which (i) is organized and doing business under the laws of any State or the
United States; (ii) is authorized under such laws to exercise corporate trust
powers; (iii) has a combined capital and surplus of at least $50,000,000; (iv)
is subject to supervision or examination by federal or state authority; (v) has
(or has a parent which has) a long-term unsecured debt rating of at least BBB-
by Standard & Poor's and at least Baa3 by Moody's Investors Service, Inc (or
such other rating as may be specified in the Series Trust Indenture) or the
equivalent rating thereof by the Rating Agency. If such corporation 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 6.11, the combined capital and surplus of such
corporation shall be deemed to be its combined capital and surplus as set forth
in its most recent report of condition so published. If at any time the Trustee
shall cease to be eligible in accordance with the provisions of this Section
6.11, the Trustee shall resign immediately in the manner and with the effect
specified in Section 6.8. The Indenture Trustee shall comply with TIA Section
310(b); provided, however, that there shall be excluded from the operation of
TIA Section 310(b)(1) any indenture or indentures under which other securities
of the Issuer are outstanding if the requirements for such exclusion set forth
in TIA Section 310(b)(1) are met.

                  SECTION 6.12 Preferential Collection of Claims Against Issuer.
The Indenture Trustee shall comply with TIA Section 311(a), excluding any
creditor relationship listed in TIA Section 311(b). A trustee who has resigned
or been removed shall be subject to TIA Section 311(a) to the extent required by
TIA Section 311(a).

                  SECTION 6.13 Representations and Warranties of Indenture
Trustee. The Indenture Trustee represents and warrants as of the Closing Date
that:

                  (a) the Indenture Trustee is an entity of the type set forth
in the Series Trust Indenture and is duly organized, validly existing and in
good standing under the laws of the State of its organization, as set forth in
the Series Trust Indenture;

                  (b) the Indenture Trustee has full power, authority and legal
right to execute, deliver and perform this Indenture, and has taken all
necessary action to authorize the execution, delivery and performance by it of
this Indenture;

                  (c) the execution, delivery and performance by the Indenture
Trustee of this Indenture (i) does not violate any provision of any law or
regulation governing the banking and trust powers of the Indenture Trustee or
any order, writ, judgment or decree of any court, arbitrator, or governmental
authority applicable to the Indenture Trustee or any of its assets, (ii) does
not violate any provision of the corporate charter or by-laws of the Indenture
Trustee, or (iii) does not violate any

provision of, or constitute, with or without notice or lapse of time, a default
under, or result in the creation or imposition of any Lien on any properties
included in the Issuer pursuant to the provisions of any mortgage, indenture,
contract, agreement or other undertaking to which it is a party, which
violation, default or Lien could reasonably be expected to have a materially
adverse effect on the Indenture Trustee's performance or ability to perform its
duties under this Indenture or on the transactions contemplated in this
Indenture;

                  (d) the execution, delivery and performance by the Indenture
Trustee of this Indenture does not require the authorization, consent or
approval of, the giving of notice to, the filing or registration with, or the
taking of any other action in respect of, any governmental authority or agency
regulating the banking and corporate trust activities of the Indenture Trustee;
and

                  (e) this Indenture has been duly executed and delivered by the
Indenture Trustee and constitutes the legal, valid and binding agreement of the
Indenture Trustee, enforceable in accordance with its terms.

                  SECTION 6.14 Indenture Trustee May Enforce Claims Without
Possession of Notes. All rights of action and claims under this Indenture or the
Notes may be prosecuted and enforced by the Indenture Trustee without the
possession of any of the Notes or the production thereof in any proceeding
relating thereto, and any such proceeding instituted by the Indenture Trustee
shall be brought in its own name as Indenture Trustee. Any recovery of judgment
shall, after provision for the payment of the reasonable compensation, expenses,
disbursements and advances of the Indenture Trustee, its agents and counsel, be
for the ratable benefit of the Noteholders in respect of which such judgment has
been obtained.

                  SECTION 6.15 Suit for Enforcement. If an Event of Default
shall occur and be continuing, the Indenture Trustee in its discretion may,
subject to the provisions of Section 6.1, proceed to protect and enforce its
rights and the rights of the Noteholders under this Indenture by Proceeding
whether for the specific performance of any covenant or agreement contained in
this Indenture or in aid of the execution of any power granted in this Indenture
or for the enforcement of any other legal, equitable or other remedy as the
Indenture Trustee, being advised by counsel, shall deem most effective to
protect and enforce any of the rights of the Indenture Trustee or the
Noteholders.

                  SECTION 6.16 Rights of Noteholders to Direct Indenture
Trustee. Holders of Notes evidencing not less than a majority of the Outstanding
Amount of the Notes shall have the right to direct the time, method and place of
conducting any Proceeding for any remedy available to the Indenture Trustee or
exercising any trust or power conferred on the Indenture Trustee; provided,
however, that subject to Section 6.1, the Indenture Trustee shall have the right
to decline to follow any such direction if the Indenture Trustee being advised
by counsel determines that the action so directed may not lawfully be taken, or
if the Indenture Trustee in good faith shall, by a Responsible Officer,
determine that the proceedings so directed would be illegal or subject it to
personal liability or be unduly prejudicial to the rights of Noteholders not
parties to such direction; and provided, further, that nothing in this Indenture
shall impair the right of the Indenture Trustee to take any action deemed proper
by the Indenture Trustee and which is not inconsistent with such direction by
the Noteholders.

in such form as the Indenture Trustee may reasonably require, to the extent such
information is in the possession or control of the Owner Trustee or any of its
agents, of the names and addresses of the Noteholders as of the most recent
Record Date, provided, however, that so long as the Indenture Trustee is the
Note Registrar, no such list shall be required to be furnished. If the Indenture

Indenture Trustee shall furnish or cause to be furnished to the Owner Trustee,

counterparty to any Credit Enhancement Agreement (in accordance with any
priority of payment set forth in the Series Trust Indenture), any amounts due to
such Person from the Issuer on such date pursuant to the terms of the Swap
Agreement, the relevant Related Agreement or the relevant Credit Enhancement

otherwise remit the aggregate of such amounts to the Owner Trustee, and (iii)
retain in the Collection Account any amounts due to the Issuer and received from
such Person on such date pursuant to the terms of the Swap Agreement, the
relevant Related Agreement or the relevant Credit Enhancement Agreement.

                  (b) On each Distribution Date and Redemption Date, the
Indenture Trustee shall, after paying any amounts due under the Swap Agreement,
any Related Agreement or any Credit Enhancement Agreement, as provided in
Section 8.4(a), (i) pay the Noteholders, in accordance with this Indenture, all
amounts due and payable to Noteholders on the respective Class of Notes, and
then (ii) if appointed as the Paying Agent under the Trust Agreement, on behalf
of the Owner Trustee, distribute from the Collection Account to the
Certificateholders, on a pro rata basis, all amounts then remaining on deposit

                  (f) The amount of any withholding tax imposed with respect to
a Noteholder pursuant to Section 3.3(c)(v) shall be treated as cash distributed
to such Noteholder at the time it is withheld by the Indenture Trustee and
remitted to the appropriate taxing authority. If there is a possibility that
withholding tax is payable with respect to a distribution (such as a
distribution to a Noteholder that is a non-U.S. Person), the Indenture Trustee
may in its sole discretion withhold such amounts in accordance with Section
3.3(c)(v). If a Noteholder wishes to apply for a refund of any such withholding
tax, the Indenture Trustee shall reasonably cooperate with such Noteholder in
making such claim so long as such Noteholder agrees to reimburse the Indenture
Trustee for any out-of-pocket expenses incurred. The Indenture Trustee shall not
be liable to any Person for withholding or failing to withhold any such
withholding tax.

                  (g) If the Indenture Trustee has received any amount from any
Person in respect of distributions of interest on the Collateral Obligations and
such Person is entitled to require and requires, that the Indenture Trustee
repay such amounts, the Indenture Trustee shall have the right to reimbursement
of any such amounts, from the Noteholders with respect to any such amounts
distributed to Noteholders and shall, to the extent provided for in favor of the
Issuer under the Swap Agreement, any Related Agreement or any Credit Enhancement
Agreement, seek reimbursement of any such amounts from the relevant party under
such agreement, including in each case any amounts payable to Noteholders or
Certificateholders pursuant to Section 10.3 below.

                  (h) Notwithstanding any other provisions in this Indenture,
the right of any Noteholder to receive payment of principal of and interest on a
Note on or after their due dates, and to institute suit for the enforcement of
any such payment on or after the date such payment is payable, shall not be
impaired without the consent of such Noteholder.

                  SECTION 8.5 Release of Trust Estate.

                  (a) Subject to the payment of its fees and expenses pursuant
to Section 6.7, the Indenture Trustee may and when required by the provisions of
this Indenture shall execute instruments to release property from the Lien of
this Indenture, or convey the Indenture Trustee's interest in the same, in a
manner and under circumstances that are consistent with the provisions of this
Indenture. No party relying upon an instrument executed by the Indenture Trustee
as provided in this Article VIII shall be bound to ascertain the Indenture
Trustee's authority, inquire into the satisfaction of any conditions precedent
or see to the application of any moneys.

                  (b) The Indenture Trustee shall at such time as there are no
Notes Outstanding and all sums due to the Indenture Trustee pursuant to Section
6.7 have been paid, release any remaining portion of the Trust Estate that
secured the Notes from the Lien of this Indenture and release to the Issuer or
any other Person entitled thereto any funds then on deposit in the Designated
Accounts. The Indenture Trustee shall release property from the Lien of this
Indenture pursuant to this Section 8.5(b) only upon receipt of an Issuer Request
accompanied by an Officer's Certificate, an Opinion of Counsel and (if required
by the TIA) Independent Certificates in accordance with TIA Sections 314(c) and
314(d)(1) meeting the applicable requirements of Section 11.1.

         3.10 and the applicable provisions hereof, of another person to the
         Issuer, and the assumption by any such successor of the covenants of
         the Issuer contained herein and in the Notes contained;

                  (iii) to add to the conditions, limitations and restrictions
         on terms of the Notes and to the covenants of the Issuer, for the
         benefit of the Noteholders, or to surrender any right or power herein
         conferred upon the Issuer;

                  (iv) to convey, transfer, assign, mortgage or pledge any
         property to or with the Indenture Trustee;

                  (v) to cure any ambiguity, to correct or supplement any
         provision herein or in any supplemental indenture which may be
         inconsistent with any other provision herein or in any supplemental
         indenture;

                  (vi) to make any amendment necessary or desirable to maintain
         the federal income tax status of the issuer;

                  (vii) to evidence and provide for the acceptance of
         appointment by a successor trustee with respect to the Notes;

         Indenture as shall be necessary to facilitate the administration of the
         trusts hereunder by more than one trustee, pursuant to the requirements
         of Article VI;

                  (ix) to amend the provisions of this Indenture relating to
         authentication and delivery of a series; or

                  (x) to modify, eliminate or add to the provisions of this
         Indenture to such extent as shall be necessary to effect the Indenture
         Trustee's qualification or the qualification of this Indenture under
         the TIA or under any similar federal statute hereafter enacted and to
         add to this Indenture such other provisions as may be expressly
         required by the TIA, and the Indenture Trustee is hereby authorized to
         join in the execution of any such supplemental indenture and to make
         any further appropriate agreements and stipulations that may be therein
         contained.

                  (b) The Issuer (subject to the terms of the Trust Agreement)
and the Indenture Trustee, when authorized by an Issuer Order, may without the
consent of any of the Noteholders, but with prior notice to the Rating Agency,
at any time and from time to time, add any provisions to, or change in any
manner or eliminate any of the provisions of, this Indenture or modify in any
manner the rights of the Noteholders under this Indenture with respect to
matters or questions arising under this Indenture; provided, however, that such

material respect the interest of any Noteholder.

                  SECTION 9.2 Supplemental Indenture With Consent of
Noteholders.

                  (a) The Issuer (subject to the terms of the Trust Agreement)
and the Indenture Trustee, when authorized by an Issuer Order, may with prior
notice to the Rating Agency and with the consent of the Holders of not less than
a majority of the Outstanding Amount of each class of Notes affected (by Act of
such Noteholders delivered to the Issuer and the Indenture Trustee), enter into
an indenture or indentures supplemental hereto for the purpose of adding any
provision to, or changing in any manner or eliminating any of the provision of,
this Indenture or of modifying in any manner the rights of the Noteholders under
this Indenture; provided, however, that no such supplemental indenture shall,

         principal of or interest on any Note, or reduce the Principal Balance
         thereof, the interest applicable thereto or the Redemption Price with

         requiring the application of funds available therefor, as provided in
         Article V, to the payment of any such amount due on the Notes on or
         after the respective due date thereof (or, in the case of redemption,
         on or after the Redemption Date);

                  (ii) reduce the percentage of the Outstanding Amount of the

         Balance of and accrued but unpaid interest on the Outstanding Notes;

                  (v) reduce the percentage of the Outstanding Amount of the
         Notes required to amend the sections of this Indenture which specify

         parity with the Lien of this Indenture with respect to any part of the
         Trust Estate or, except as otherwise permitted or contemplated herein,
         terminate the Lien of this Indenture on any property at any time
         subject hereto or deprive any Noteholder of the security provided by
         the Lien of this Indenture; or

                  (vii) modify any of the provisions of this Indenture if the
         modification affects the calculation of the amount of any payment of
         interest or principal due and payable on any Note on any Distribution
         Date or affects the rights of the Noteholders of any Class to the
         benefit of any provisions for the mandatory redemption of Notes of that
         Class.

                  (b) The Indenture Trustee may in its discretion determine
whether or not any Notes would be affected (such that the consent of the Holder

indenture proposed pursuant to this Section 9.2, and any such determination
shall be conclusive upon all the Noteholders, whether authenticated and
delivered thereunder before or after the date upon which such supplemental
indenture becomes effective. The Indenture Trustee shall not be liable for any
such determination made in good faith.

                  (c) It shall be sufficient if an Act of Noteholders approves
the substance, but not the form, of any proposed supplemental indenture.

                  (d) Promptly after the execution by the Issuer and the
Indenture Trustee of any supplemental indenture pursuant to this Section 9.2,
the Indenture Trustee shall mail to the Rating Agency and the Noteholders to
which such amendment or supplemental indenture relates a notice setting forth in
general terms the substance of such supplemental indenture. Any failure of the
Indenture Trustee to mail such notice, or any defect therein, shall not,
however, in any way impair or affect the validity of any such supplemental
indenture.

                  SECTION 9.3 Execution of Supplemental Indentures. In executing
or permitting the additional trusts created by any supplemental indenture
permitted by this Article IX or the modifications thereby of the trusts created

subject to Sections 6.1 and 6.2, shall be fully protected in relying upon, an
Opinion of Counsel stating that the execution of such supplemental indenture is
authorized or permitted by this Indenture. The Indenture Trustee may, but shall
not be obligated to, enter into any such supplemental indenture that affects the
Indenture Trustee's own rights, duties, liabilities or immunities under this
Indenture or otherwise.

                  SECTION 9.4 Effect of Supplemental Indenture. Upon the
execution of any supplemental indenture pursuant to the provisions hereof, this
Indenture shall be and be deemed to be modified and amended in accordance
therewith with respect to the Notes affected thereby, and the respective rights,
limitations of rights, obligations, duties, liabilities and immunities under
this Indenture of the Indenture Trustee, the Issuer and the Noteholders shall
thereafter be determined, exercised and enforced hereunder, subject in all
respects to such modifications and amendments, and all the terms and conditions
of any such supplemental indenture shall be and be deemed to be part of the

effect.

Notes authenticated and delivered after the execution of any supplemental
indenture pursuant to this Article IX may, and if required by the Indenture

indenture may be prepared and executed by the Issuer and authenticated and
delivered by the Indenture Trustee in exchange for Outstanding Notes.

                  SECTION 10.1 Redemption.

                  (a) If any or all of the Collateral Obligations of any issue

Trustee of notice of such redemption or upon publication to that effect in The
Bond Buyer, the Wall Street Journal or The New York Times, each of which the
Indenture Trustee shall review on a regular basis, the Indenture Trustee shall,
in accordance with the provisions of this Article X, redeem a Principal Balance
of Notes equal to the Principal Balance of the Collateral Obligations of such
issue then being redeemed. In the absence of the actual notice or publication
described in this Section 10.1, the Indenture Trustee shall be under no
obligation to effect the redemption required by this Section 10.1.

                  (b) In the event of such a redemption of Notes, the Indenture
Trustee shall deposit amounts received in respect of the underlying Collateral
Obligations in the Collection Account. Within 15 days of the receipt of funds in
the Collection Account, the Indenture Trustee shall redeem an aggregate
Principal Balance of Notes equal to the product of (x) the Outstanding Amount of
Notes and (y) a fraction the numerator of which is the aggregate Principal
Balance of the Collateral Obligations being redeemed by the issuer thereof and
the denominator of which is the aggregate Principal Balance of the Collateral
Obligations included in the Trust Estate.

                  (c) If the assets of the Issuer are sold pursuant to Section
8.2 of the Trust Agreement, all amounts on deposit in the Collection Account (or
such other account as may have been created by the Indenture Trustee for payment
of amounts to the Noteholders) previously allocated for payment to the
Noteholders shall be paid to the Noteholders. If amounts are to be paid to
Noteholders pursuant to this Section 10.1(c), the Issuer shall, or procure that
the Depositor shall, to the extent practicable, furnish notice of such event to
the Indenture Trustee not later than 25 days prior to the Redemption Date,
whereupon all such amounts shall be payable on the Redemption Date.

                  SECTION 10.2 Notice of Redemption. Notice of redemption shall
be given by the Indenture Trustee to each Noteholder of any Note to b6+e
redeemed within 30 days after notice of redemption of the underlying Collateral
Obligations has been given by the issuer, trustee or paying agent of or for the
Collateral Obligations, as the case may be (but not less than 15 days prior to
the redemption date); provided, however, that the Indenture Trustee shall not be
required to give any notice of redemption less than 3 Business Days after the
date it receives notice of such redemption. All notices of redemption shall be
mailed to each Noteholder at such Noteholder's last address on the Note Register
and shall state the Redemption Date, the amount payable on such date, the place
at which Notes are to be surrendered for payment and that interest on amounts
redeemed will cease to accrue.

                  Notice of redemption of the Notes shall be given by the
Indenture Trustee in the name and at the expense of the Issuer. Failure to give
notice of redemption, or any defect therein, to any Noteholder shall not impair
or affect the validity of the redemption of any other Note.

                  SECTION 10.3 Liquidation of Collateral Obligations Upon
Certain Events.

                  (a) In addition to any event that will result in a Redemption
Date occurring, upon the occurrence of a Trust Liquidation Event the Indenture
Trustee shall, upon receipt of notice thereof from the Owner Trustee, or upon
the Indenture Trustee obtaining actual knowledge of any occurrence of a Trust
Liquidation Event, promptly give notice of such occurrence to the Noteholders.

                  (b) Upon the occurrence of a Trust Liquidation Event, the
Indenture Trustee shall, subject to the rights of the Noteholders set forth
herein, cause the Trust Assets to be liquidated in the manner required by the
Owner Trustee. The proceeds of such liquidation shall be credited to the
Collection Account and the Indenture Trustee shall:

                           (i) on behalf of the Owner Trustee, (A) withdraw from
         the Collection Account such amounts as are necessary to satisfy the
         expenses of the Issuer, to the extent not paid

         (B) withdraw from the Collection Account and if appointed as the Paying
         Agent under the Trust Agreement, remit first to the Swap Counterparty,
         then to the counterparty to any Related Agreement, and then to the
         counterparty to any Credit Enhancement Agreement (in accordance to any
         priority of payments specified in the Series Trust Indenture), any
         amounts due to such Person from the Issuer on such date pursuant to the
         terms of the Swap Agreement, the relevant Related Agreement or the
         relevant Credit Enhancement Agreement (net of amounts due to the Issuer
         from such Person on such date), and otherwise remit the aggregate of
         such amounts to the Owner Trustee, and (iii) retain in the Collection
         Account any amounts due to the Issuer and received from such Person on
         such date pursuant to the terms of the Swap Agreement, the relevant
         Related Agreement or the relevant Credit Enhancement Agreement.

                           (ii) after paying any amounts due under the Swap
         Agreement, any Related Agreement or any Credit Enhancement Agreement as
         provided in Section 10.3(b)(i) above, (A) pay the Noteholders, in
         accordance with this Indenture, all amounts due in respect of the
         respective Class of Notes, and then (B) if appointed as the Paying
         Agent under the Trust Agreement, on behalf of the Owner Trustee
         distribute from the Collection Account to the Certificateholders, on a
         pro rata basis, all amounts then remaining on deposit in the Collection
         Account, and otherwise remit the aggregate of such amounts to the Owner
         Trustee.

                  (c) The proceeds and the timing of the sale of the Collateral
Obligations by the Indenture Trustee on behalf of the Owner Trustee shall be at
the risk of the Swap Counterparty, the counterparty to any Related Agreement or
any Credit Enhancement Agreements, the Owner Trustee, the Noteholders and the
Certificateholders and without recourse to the Indenture Trustee, who shall
execute such sales based on advice obtained pursuant to Section 10.3(d) below
and apply the proceeds of the sale as set forth in Section 10.3(b).

                  (d) For purposes of any determinations required by this
Section 10.3, including (i) the making of any Market Quotation determination or
Loss determination by the Indenture Trustee under the Swap Agreement and (ii)
advice on the pricing and timing of sales of the Collateral Obligations, the
Indenture Trustee shall be entitled to receive and conclusively rely on the
instructions of the Owner Trustee or any Calculation Agent and certifications
provided by an investment bank selected in good faith and in a reasonable manner
by the Indenture Trustee and will not be subject to any liability for such
reliance thereon.

                                   ARTICLE XI
                                  MISCELLANEOUS

         fair value (within 90 days of such deposit) to the Issuer of the

         Obligations or other property or securities to be so released, each in
         compliance with TIA Section 314(d).

                  (ii) Whenever the Issuer is required to furnish to the
         Indenture Trustee an Officer's Certificate certifying or stating the
         opinion described in clause (b)(i) above, the Issuer shall also deliver

                  (v) Notwithstanding Section 2.10 or any other provision of
         this Section 11.1, the Issuer may make cash payments out of the
         Designated Accounts to the extent permitted or required by the Basic
         Documents.

                  SECTION 11.2 Form of Documents Delivered to Indenture Trustee.

                  (a) In any case where several matters are required to be
certified by, or covered by an opinion of, any specified Person, it is not
necessary that all such matters be certified by, or covered by the opinion of,
only one such Person, or that they be so certified or covered by only one
document, but one such Person may certify or give an opinion with respect to
some matters and one or more other such Persons may certify or give an opinion
as to other matters, and any such Person may certify or give an opinion as to
such matters in one or several documents.

                  (b) Any certificate or opinion of an Authorized Officer of the
Issuer or Authorized Signatory of the Owner Trustee may be based, insofar as it
relates to legal matters, upon a certificate or opinion of, or representations
by, counsel, unless such officer knows, or in the exercise of reasonable care
should know, that the certificate or opinion or representations with respect to
the matters upon which the certificate or opinion is based are erroneous. Any
such certificate of an Authorized Officer or Authorized Signatory or Opinion of
Counsel may be based, insofar as it relates to factual matters, upon a
certificate or opinion of, or representations by, an officer or officers of the
Depositor or the Issuer, stating that the information with respect to such
factual matters is in the possession of the Depositor or the Issuer, unless such
counsel knows, or in the exercise of reasonable care should know, that such
certificate or opinion or representations with respect to such matters are
erroneous.

                  (c) Where any Person is required to make, give or execute two
or more applications, requests, consents, certificates, statements, opinions or
other instruments under this Indenture, they may, but need not, be consolidated
and form one instrument.

                  (d) Whenever in this Indenture, in connection with any
application or certificate or report to the Indenture Trustee, it is provided
that the Issuer shall deliver any document as a condition of the granting of
such application, or as evidence of the Issuer's compliance with any term
hereof, it is intended that the truth and accuracy at the time of the granting
of such application or at the effective date of such certificate or report (as
the case may be), of the facts and opinions stated in such document shall in
such case be conditions precedent to the right of the Issuer to have such
application granted or to the sufficiency of such certificate or report. The
foregoing shall not, however, be construed to affect the Indenture Trustee's
right to rely upon the truth and accuracy of any statement or opinion contained
in any such document as provided in Article VI.

                  SECTION 11.3 Acts of Noteholders.

                  (a) Any request, demand, authorization, direction, notice,
consent, waiver or other action provided by this Indenture to be given or taken
by the Noteholders may be embodied in and evidenced by one or more instruments
of substantially similar tenor signed by such Noteholders in person or by agents
duly appointed in writing; and except as herein otherwise expressly provided
such action shall become effective when such instrument or instruments are
delivered to the Indenture Trustee, and, where it is hereby expressly required,
to the Issuer. Such instrument or instruments (and the action embodied therein
and evidenced thereby) are herein sometimes referred to as the "Act" of the
Noteholders signing such instrument or instruments. Proof of execution of any
such instrument or of a writing appointing any such agent shall be sufficient
for any purpose of this Indenture and (subject to Section 6.1) conclusive in
favor of the Indenture Trustee and the Issuer, if made in the manner provided in
this Section 11.3.

                  (b) The fact and date of the execution by any person of any
such instrument or writing may be proved in any manner that the Indenture
Trustee deems sufficient.

                  (c) The ownership of Notes shall be proved by the Note
Register.

                  (d) Any request, demand, authorization, direction, notice,
consent, waiver or other action by the Noteholders shall bind the Holder of
every Note issued upon the registration thereof or in exchange therefor in lieu
thereof, in respect of anything done, omitted or suffered to be done by the
Indenture Trustee or the Issuer in reliance thereon, whether or not notation of
such action is made upon such Note.

                  SECTION 11.4 Notices, etc., to Indenture Trustee, Issuer and
Rating Agency. Any request, demand, authorization, direction, notice, consent,
waiver or Act of Noteholders or other documents provided or permitted by this
Indenture to be made upon, given or furnished to or filed with:

                  (a) the Indenture Trustee by any Noteholder or by the Issuer
shall be sufficient for every purpose hereunder if made, given, furnished or
filed in writing to or with the Indenture Trustee at its Corporate Trustee
Office, or

                  (b) the Issuer by the Indenture Trustee or by any Noteholder
shall be sufficient for every purpose hereunder if in writing and either sent by
electronic facsimile transmission (with hard copy to follow via first class
mail) or mailed, by certified mail, return receipt requested to the Issuer and
the Owner Trustee, care of the Owner Trustee at its Corporate Trust Office, with
copies to the address or addresses set forth in the Series Trust Indenture, or
at any other address previously furnished in writing to the Indenture Trustee by
the Issuer.

The Issuer shall promptly transmit any notice received by it from the
Noteholders to the Indenture Trustee and the Indenture Trustee shall likewise
promptly transmit any notice received by it from the Noteholders to the Issuer.

                  (c) Notices required to be given to the Rating Agency by the
Issuer, the Indenture Trustee or the Owner Trustee shall be in writing,
personally delivered, sent by electronic facsimile transmission (with hard copy
to follow via first class mail) or mailed by certified mail, return receipt
requested to the address set forth in the Series Trust Indenture or at such
other address as shall be designated by written notice to the other parties.

                  SECTION 11.5 Notices to Noteholders; Waiver.

                  (a) Where this Indenture provides for notice to Noteholders of
any event, such notice shall be sufficiently given (unless otherwise herein
expressly provided) if it is in writing and mailed, first-class, postage prepaid
to each Noteholder affected by such event, at such Person's address as it
appears on the Note Register, not later than the latest date, and not earlier
than the earliest date, prescribed for the giving of such notice. If notice to
Noteholders is given by mail, neither the failure to mail such notice nor any
defect in any notice so mailed to any particular Noteholder shall affect the
sufficiency of such notice with respect to other Noteholders, and any notice
that is mailed in the manner herein provided shall conclusively be presumed to
have been duly given regardless of whether such notice is in fact actually
received.

                  (b) Where this Indenture provides for notice in any manner,
such notice may be waived in writing by any Person entitled to receive such
notice, either before or after the event, and such waiver shall be the
equivalent of such notice. Waivers of notice by Noteholders shall be filed with
the

Indenture Trustee but such filing shall not be a condition precedent to the
validity of any action taken in reliance upon such a waiver.

                  (c) In case, by reason of the suspension of regular mail
service as a result of a strike, work stoppage or similar activity, it shall be
impractical to mail notice of any event of Noteholders when such notice is
required to be given pursuant to any provision of this Indenture, then any
manner of giving such notice as shall be satisfactory to the Indenture Trustee
shall be deemed to be a sufficient giving of such notice.

                  (d) Where this Indenture provides for notice to the Rating
Agency, failure to give such notice shall not affect any other rights or
obligations created hereunder, and shall not under any circumstances constitute
an Event of Default.

                  SECTION 11.6 Alternate Payment and Notice Provisions.
Notwithstanding any provision of this Indenture or any of the Notes to the
contrary, the Issuer may enter into any agreement with any Noteholder providing
for a method of payment, or notice by the Indenture Trustee or any Paying Agent
to such Noteholder, that is different from the methods provided for in this
Indenture for such payments or notices. The Issuer shall furnish to the
Indenture Trustee a copy of each such agreement and the Indenture Trustee shall
cause payments to be made and notices to be given in accordance with such
agreements.

                  SECTION 11.7 Conflict with Trust Indenture Act.

                  (a) If any provision hereof limits, qualifies or conflicts
with another provision hereof that is required to be included in this Indenture
by any of the provisions of the TIA, such required provision shall control.

                  (b) The provisions of TIA Sections 310 through 317 that impose
duties on any Person (including the provisions automatically deemed included
herein unless expressly excluded by this Indenture) are a part of and govern
this Indenture, whether or not physically contained herein.

                  SECTION 11.8 Effect of Headings and Table of Contents. The
Article and Section headings herein and the Table of Contents are for
convenience only and shall not affect the construction hereof.

                  SECTION 11.9 Successors and Assigns.

                  (a) All covenants and agreements in this Indenture and the
Notes by the Issuer shall bind its successors and assigns, whether so expressed
or not.

                  (b) All covenants and agreements of the Indenture Trustee in
this Indenture shall bind its successors and assigns, whether so expressed or
not.

                  SECTION 11.10 Separability. In case any provision in this
Indenture or in the Notes shall be invalid, illegal or unenforceable, the
validity, legality, and enforceability of the remaining provisions shall not in
any way be affected or impaired.

                  SECTION 11.11 Benefits of Indenture. Nothing in this Indenture
or in the Notes, express or implied, shall give to any Person, other than the
parties hereto and their successors hereunder, and the Noteholders, and any
other party secured hereunder, and any other person with an ownership

is to be effected by the Issuer and at its expense accompanied by an Opinion of
Counsel (which may be counsel to the Indenture Trustee or any other counsel

recording is necessary either for the protection of the Noteholders or any other
Person secured hereunder or for the enforcement of any right or remedy granted
