Upon satisfaction of the requirements set forth in the preceding sentence, each
Holder of a Note shall have the right, upon surrender of such Note to the
Indenture Trustee, to require a new Note or Notes of the same Series and Class
to be issued to it or to a prospective Holder, in a minimum denomination of the
lesser of (x) $1,000,000 (or such other amount as shall be set forth in the
related Supplement) or (y) the entire principal balance of the Note being
surrendered, in substitution of the Note being surrendered.

          (d)  Any service charge made or expense incurred by the Indenture
Trustee for any such registration, discharge from registration or exchange
referred to in this Section 205 shall be paid by the Noteholder.  The Indenture
Trustee or the Issuer may require payment by the Holder of a sum sufficient to
cover any tax expense or other governmental charge payable in connection
therewith.


                                          25


          (e)  Each prospective initial Noteholder acquiring a Note, each
prospective owner acquiring a Note and each prospective owner (or transferee
thereof) of a beneficial interest in Notes acquiring such beneficial interest
shall represent and warrant in writing to the Indenture Trustee, the Issuer, the
Servicer and any successor Servicer that one of the following statements is true
and correct:  (i) the purchaser is not an "employee benefit plan" within the
meaning of Section 3(3) of ERISA or a "plan" within the meaning of Section
4975(e)(1) of the Code ("Benefit Plan") and it is not directly or indirectly
acquiring the Notes on behalf of, as investment manager of, as named fiduciary
of, as trustee of, or with assets of, a Benefit Plan, (ii) the acquisition will
qualify for a statutory or administrative prohibited transaction exemption under
ERISA and the Code and will not give rise to a non-exempt transaction described
in Section 406 of ERISA or Section 4975(c) of the Code, (iii) the source of
funds (the "Source") to be used by the Purchaser to pay the purchase price of
the Notes is a guaranteed benefit policy within the meaning of Section
401(b)(2)(B) of ERISA, or (iv) the Source to be used by the purchaser to pay the
purchase price of the Notes is an "insurance company general account" within the
meaning of Department of Labor Prohibited Transaction Exemption ("PTE") 95-60
(issued July 12, 1995), and there is no "employee benefit plan" or "plan"
(within the meaning of Section 3(3) of ERISA or Section 4975(e)(1) of the Code
as applicable, and treating as a single plan, all plans maintained by the same
employer (or an affiliate within the meaning of Section V(a)(1) of PTE 95-60) or
employee organization) with respect to which the amount of the reserves and
liabilities for the general account contracts held by or on behalf of such plan,
as defined by the annual statement for life insurance companies approved by the
National Association of Insurance Commissioners (the "NAIC Annual Statement"),
exceed ten percent (10%) of the total reserves and liabilities of such general
account (exclusive of separate account liabilities) plus surplus, as set forth
in the NAIC Annual Statement filed with the purchaser's state of domicile.

          (f)  No transfer of any Note shall be made unless such transfer is
made in a transaction which does not require registration under the Securities
Act and pursuant to an effective registration or qualification under any State
securities or "Blue Sky" laws, or in a transaction which does not require such
registration or qualification.  If such a transfer is to be made in reliance
upon an exemption from the Securities Act other than Rule 144A under the
Securities Act, the prospective owner shall furnish to the Indenture Trustee a
certificate substantially in the form of Exhibit E hereto.  If such transfer is
to be made in reliance upon Rule 144A under the Securities Act, the prospective
owner shall furnish to the Indenture Trustee a certificate, substantially in the
form of Exhibit D hereto.  The Issuer (or Servicer as agent for the Issuer)
shall promptly furnish to any Holder, or any prospective owners designated by a
Holder, the information required to be delivered to any Holder and prospective
owner in connection with a resale of the Notes to permit compliance with Rule
144A in connection with such resale.  No Note may be subdivided (including any
assignment or transfer of a participation or beneficial interest therein) for
resale or other transfer into a unit smaller than a unit the initial offering
price of which would have been $1,000,000 (or such other amount as shall be set
forth in the related Supplement.)

          Section 206.   MUTILATED, DESTROYED, LOST AND STOLEN NOTES.  (a)  If
(i) any mutilated Note is surrendered to the Indenture Trustee, or the Indenture
Trustee receives evidence to its satisfaction of the destruction, loss or theft
of any Note, and (ii) there is delivered to the Indenture Trustee such security
or indemnity as it and the Issuer may require to hold the Issuer, the Servicer
and the Indenture Trustee harmless (the unsecured indemnity of a Rated
Institutional Noteholder being deemed satisfactory for such purpose unless the
Indenture Trustee provides written notice to the contrary), then the Issuer
shall execute and 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 the same Series and Class and maturity and of like terms as
the mutilated, destroyed, lost or stolen Note; PROVIDED, HOWEVER, that if any
such destroyed, lost or stolen Note, but not a mutilated Note, shall have
become, or within seven days shall be, due and payable, or shall have been
called for redemption, the Issuer may pay such destroyed, lost or stolen Note
when so due or payable instead of issuing a replacement Note.

          (b)  If, after the delivery of such replacement Note, or payment of a
destroyed, lost or stolen Note pursuant to the proviso to the preceding
sentence, a bona fide purchaser of the original Note in lieu of which such
replacement Note was issued presents for payment such original Note, the Issuer
and the Indenture Trustee shall be entitled to recover upon the security or
indemnity provided therefor to the extent of any loss, damage, cost or expense
incurred by the Issuer or the Indenture Trustee in connection therewith.

          (c)  The Indenture Trustee and Issuer may, for each new Note
authenticated and delivered under the provisions of this Section 206, require
the advance payment by the Noteholder of the expenses, including counsel fees,
service charges and any tax or governmental charge which may be incurred by the
Indenture Trustee or Issuer.  Any Note issued under the provisions of this
Section 206 in lieu of any Note alleged to be destroyed, mutilated, lost or
stolen, shall be equally and proportionately entitled to the benefits of this
Indenture with all other Notes of the same Series and Class.  The provisions of
this Section 206 are exclusive and shall preclude (to the extent lawful) all
other rights and remedies with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Notes.

          Section 207.   DELIVERY, RETENTION AND CANCELLATION OF NOTES.  Each
Noteholder is required, and hereby agrees, to return to the Indenture Trustee,
within 30 days after the Final Payment Date, any Note on which the final payment
due thereon has been made.  Any such Note as to which the Indenture Trustee has
made or holds the final payment thereon shall be deemed cancelled and shall no
longer be Outstanding or outstanding for any purpose of this Indenture, whether
or not such Note is ever returned to the Indenture Trustee unless any
unreimbursed payment on such Note has been made by a Series Enhancer.  Matured
Notes delivered upon final payment to the Indenture Trustee and any Notes
transferred or exchanged for other Notes shall be cancelled and disposed of by
the Indenture Trustee in accordance with its policy of disposal and the
Indenture Trustee shall promptly deliver to the Issuer such cancelled Notes upon
request; PROVIDED, HOWEVER, that the Indenture Trustee shall not be required
to destroy cancelled Notes.  If the Indenture Trustee, for its own account,
shall

                                          27


acquire any of the Notes, such acquisition shall not operate as a redemption 
or satisfaction of the indebtedness represented by such Notes. If the Issuer 
shall acquire any of the Notes, such acquisition shall operate as a 
redemption or satisfaction of the indebtedness represented by such Notes. 
Notes which have been cancelled by the Indenture Trustee shall be deemed paid 
and discharged for all purposes under this Indenture.

                                          28

                     PAYMENT OF NOTES; STATEMENTS TO NOTEHOLDERS

          Section 301.   PRINCIPAL AND INTEREST.  Distributions of principal and
interest on any Series or Class of Notes shall be made to Noteholders of each
Series and Class as set forth in this Indenture and the related Supplement.  The
maximum Overdue Rate for any Note under any Series shall be 2.00% plus the
interest rate for such Note prior to the default.  If interest or principal
amounts are paid by a Series Enhancer, then the Overdue Rate shall be applicable
to any Class of Notes only if the related Series Enhancer has failed to make
payment of such amounts in accordance with the terms of any applicable Series
Enhancement Agreement.

          Section 302.   DIRECTION TO LESSEES.  On or prior to each Transfer
Date, the Issuer shall (or shall cause the Servicer to) mail a notice to each
Lessee under the Lease Agreements contributed to the Issuer pursuant to the
Contribution and Sale Agreement on such Transfer Date informing such Lessee that
all payments including, without limitation, all Scheduled Payments, Maintenance
Reserve Payments and Security Deposits, with respect to the related Lease
Agreement should be submitted directly to the Trust Account; PROVIDED, HOWEVER,
that such notice shall provide that any indemnification payments and liability
insurance payments shall not be deposited in the Trust Account but shall be paid
directly to the person entitled to such indemnification or insurance payment.

          Section 303.   TRUST ACCOUNT.  (a)  On or prior to the Effective Date
of the first Series, the Issuer shall establish and maintain the Trust Account
into which all Collections (other than amounts received from manufacturers or
sellers of an Eligible Engine for breach of sale warranties or in settlement of
any claims, losses, disputes or proceedings related thereto for which a
corresponding amount has previously been paid by the Issuer, Seller or Servicer
to the Trust Account), Prepayments after an Early Amortization Event,
Prepayments designated by the Issuer to be deposited in the Trust Account prior
to the occurrence of an Early Amortization Event, Warranty Purchase Amounts and
other payments required by this Indenture shall be deposited.  Such Trust
Account shall be established and maintained with the Corporate Trust Office of
the Indenture Trustee in trust for the Indenture Trustee, on behalf of the
Noteholders and any Series Enhancer, until the Aggregate Outstanding Obligations
are paid in full.  The Trust Account shall be an Eligible Account and shall be
pledged to the Indenture Trustee pursuant to the terms of this Indenture. 
Promptly upon receipt thereof (but in no event later than two Business Days
after receipt), the Servicer shall deposit into the Trust Account those amounts
that have been remitted directly to the Servicer that the Servicer ascertains to
be Engine Revenues, Sales Proceeds or Casualty Proceeds in respect of any of the
Eligible Engines; PROVIDED, HOWEVER, that indemnification payments and liability
insurance payments received by the Issuer or the Servicer shall not be deposited
in the Trust Account but shall be paid directly to the Person entitled to such
indemnification or insurance payment.  The Issuer shall not establish any
additional Trust Accounts without prior written notice to the Indenture Trustee.


                                          29


          (b)  By not later than each Determination Date, the Servicer, pursuant
to the Servicing Agreement, shall instruct in writing the Indenture Trustee to
allocate all Collections and Prepayments for the related Collection Period then
on deposit in the Trust Account to each Series Account (PROVIDED, HOWEVER, that
the Servicer shall instruct in writing the Indenture Trustee to allocate any
Maintenance Reserve Payments and Security Deposits directly to each Engine
Reserve Account and Security Deposit Account, respectively, for each Series) by
specifically identifying such Collections and Prepayments (and such Maintenance
Reserve Payments and Security Deposits) to a particular Eligible Engine and then
instructing in writing the Indenture Trustee to allocate all of such amounts to
the Series Account, the Engine Reserve Account and the Security Deposit Account
for the Series to which such Eligible Engine is pledged.  In addition, the
Servicer shall instruct in writing the Indenture Trustee to allocate any
earnings on Eligible Investments in the Trust Account to the Series Account for
each Series then Outstanding in the same proportion as the ratio of the
Outstanding Obligations of such Series to the Aggregate Outstanding Obligations.

          (c)  If any Series has more than one Class of Notes then Outstanding,
then the portion of the investment earnings in the Trust Account allocable to
such Series pursuant to Section 303(b) shall be calculated without giving effect
to the payment priorities of the Classes of such Series.  Once such Collections
and investment earnings have been allocated to each Series, then that portion of
the Collections allocable to such Series shall be paid to each Class of
Noteholders of such Series in accordance with the priority of payments set forth
in the related Supplement.

          Section 304.   INVESTMENT OF MONIES HELD IN THE TRUST ACCOUNT, THE
RESTRICTED CASH ACCOUNT, ENGINE RESERVE ACCOUNT, THE SECURITY DEPOSIT ACCOUNT
AND SERIES ACCOUNTS.  The Indenture Trustee shall invest any cash deposited in
the Trust Account, the Engine Reserve Account, the Security Account, the
Restricted Cash Account for each Series and each Series Account in such Eligible
Investments as the Servicer shall direct in writing or by telephone, confirmed
in writing.  Each Eligible Investment (including reinvestment of the income and
proceeds of Eligible Investments) shall be held to its maturity and shall mature
or shall be payable on demand not later than the Business Day immediately
preceding the next succeeding Payment Date.  If the Indenture Trustee has not
received written instructions from the Servicer by 2:30 p.m. (New York time) on
the day such funds are received as to the investment of funds then on deposit in
any of the aforementioned accounts, the Issuer hereby instructs the Indenture
Trustee to invest such funds in overnight investments of the type described in
clause (ii) of the definition of Eligible Investments.  Any funds in the Trust
Account, the Engine Reserve Account, the Security Deposit Account, each
Restricted Cash Account and each Series Account not so invested must be fully
insured by the Federal Deposit Insurance Corporation.  Eligible Investments
shall be made in the name of the Indenture Trustee for the benefit of the
Noteholders and any Series Enhancer.  Any earnings on Eligible Investments in
the Trust Account, the Engine Reserve Account, the Security Deposit Account,
each Restricted Cash Account and each Series Account shall be retained in each
such account and be distributed in accordance with the terms of this Indenture
or any related Supplement.


                                          30

investments made by it pursuant to this Section 303.
          Section 305.   REPORTS TO NOTEHOLDERS.  The Indenture Trustee shall
promptly upon request furnish to each Noteholder and each Series Enhancer a copy

Trustee shall deliver at least monthly an accounting thereof in the form of a
trust statement to the Issuer, the Seller and the Servicer and each Series
Enhancer.

          Section 307.   RESTRICTED CASH ACCOUNT.  The Issuer shall establish
and maintain an account with the Corporate Trust Office of the Indenture Trustee
with subaccounts for each Series, as provided in the related Supplement for a
Series,  which shall be designated the restricted cash account (the "Restricted
Cash Account") for each such Series and which shall be pledged to the Indenture
Trustee pursuant to this Indenture and the related Supplement.  Any and all
moneys remitted by the Issuer, or Servicer on its behalf, to the Restricted Cash
Account from the Trust Account, together with any Eligible Investments in which
such moneys are or will be invested or reinvested, shall be held in the
Restricted Cash Account subaccount for each such Series.

          Section 308.   ENGINE RESERVE ACCOUNT.  (a) The Issuer shall establish
and maintain an account with the Corporate Trust Office of the Indenture Trustee
with subaccounts for each Series, as provided in the related Supplement for a
Series, which shall be designated the engine account (the "Engine Reserve
Account") for each such Series and which shall be pledged to the Indenture
Trustee pursuant to this Indenture and the related Supplement.  The Maintenance
Reserve Payments remitted by the Issuer, the Servicer on its behalf or by the
Lessee, as provided in the related Supplement for a Series, to the Engine
Reserve Account from the Trust Account, together with any Eligible Investments
in which such moneys are or will be invested or reinvested, shall be held in the
Engine Reserve Account subaccount for each such Series.

          (b)  The Issuer shall maintain (or shall cause the Servicer to
maintain) records that will identify amounts on deposit in the Engine Reserve
Account subaccount to a specific Eligible Engine.  The Servicer shall be
entitled to withdraw funds from the Engine Reserve Account for the payment of
maintenance expenses with respect to the related Eligible Engine, at the times
and subject to the further conditions set forth in the Servicing Agreement;
provided, however, that so long as a Servicer Default is then in effect, the
Servicer shall not be entitled to make such withdrawal except upon presentation
of supporting documentation reasonably determined by the Administrative Agent to
comply with the terms of the applicable


                                          31


Lease Agreement (which shall evidence its determination by written instrument
delivered to the Indenture Trustee).

          Section 309.   SECURITY DEPOSIT ACCOUNT.  (a) The Issuer shall
establish and maintain an account with the Corporate Trust Office of the
Indenture Trustee with subaccounts for each Series, as provided in the related
Supplement for a Series, which shall be designated the security deposit account
(the "Security Deposit Account") for each such Series and which shall be pledged
to the Indenture Trustee pursuant to this Indenture and the related Supplement.

the Lessees, as provided in the related Supplement for a Series, to the Security

Servicer shall not be entitled to make such withdrawal except upon presentation
of supporting documentation reasonably determined by the Administrative Agent to
comply with the terms of the applicable Lease Agreement (which shall evidence
its determination by written instrument delivered to the Indenture Trustee).

          Section 310.   SECURITIES ACCOUNTS.

          (a)  Notwithstanding any other provision of this Indenture or any
Supplement, with respect to each of the Securities Accounts, the Securities
Intermediary hereby agrees that it will comply with entitlement orders (as such
term is defined under UCC Section 8-102(a)(8)) originated by the Indenture
Trustee without further consent by the Issuer.

          (b)  Each of the Issuer, the Securities Intermediary and the Indenture
Trustee intends that the provisions of Section 310(a) will give the Indenture
Trustee "control" over the Securities Accounts (as the term "control" is defined

                                      COLLATERAL

          Section 401.   COLLATERAL.  (a)  The Notes and the obligations of the
Issuer hereunder shall be an obligation of the Issuer as provided in Section 203
hereof.  The Indenture Trustee, for the benefit of the Noteholders of all
Series, and the Noteholders of a particular Series and the Series Enhancer (if
any) of such Series, all in accordance with the Supplement for such Series,
shall also have the benefit of, and the Notes of such Series shall be secured by
and be payable from, the Issuer's right, title and interest in that portion of
the Collateral allocated or identified to such Series in accordance with the
terms of this Indenture and the Supplement pursuant to which such Notes were
issued.

          (b)  Notwithstanding anything contained in this Indenture to the
contrary, the Issuer expressly agrees that it shall remain liable under each of
its Contracts to observe and perform all the conditions and obligations to be
observed and performed by it thereunder and that it shall perform all of its
duties and obligations thereunder, all in accordance with and pursuant to the
terms and provisions of each such Contract.

          (c)  Pursuant to the Servicing Agreement the Issuer shall cause the
Servicer to collect the Accounts in accordance with the Servicer's normal
business practice; PROVIDED, HOWEVER, that the Indenture Trustee, with the
consent of, or at the direction of, the Requisite Global Majority, may, without
notice, limit or terminate such authority upon (i) the occurrence of an Event of
Default described in Section 801(ii) hereof, or (ii) any Sale of the Collateral
pursuant to Section 816 hereof or (iii) the occurrence of a Servicer Default. 
Any Proceeds subsequently received in payment of any such Account or in payment
for any of the Eligible Engines or on account of any of its Contracts shall be
promptly deposited by the Issuer in precisely the form received (with all
necessary endorsements) in the Trust Account as hereinafter provided, and until
so turned over shall be deemed to be held in trust by the Issuer for and as
Indenture Trustee's property.  Such Proceeds, when deposited, shall continue to
be collateral security for all of the obligations secured by this Indenture and
shall not constitute payment thereof until applied as hereinafter provided. 
Upon (i) the occurrence of an Event of Default described in Section 801(ii), or
(ii) any Sale of the Series Collateral pursuant to Section 816 hereof or (iii)
the occurrence of a Servicer Default, the Issuer shall at the request of
Indenture Trustee, with the consent of or at the direction of the Requisite
Global Majority, to the extent practicable, deliver to the Indenture Trustee (or
such other Person as the Indenture Trustee may direct) all original Lease
Agreements and any other documents evidencing, and relating to, the sale, lease
and delivery of the Eligible Engines and the Issuer shall, to the extent
practicable, deliver all original and other documents evidencing and relating
to, the performance of any labor, maintenance, remarketing or other service
which gave rise to such Accounts, including, without limitation, all original
orders, invoices and shipping receipts.


                                          33


          (d)  In order to secure the Outstanding Obligations under each
Supplement to this Indenture, the Issuer hereby pledges, assigns, grants,
transfers and conveys to the Indenture Trustee, on behalf of the Noteholders of
all Series, a lien on and first priority security interest in all Excess Cash
Available for Distribution pursuant to Section 302 of each Supplement (or such
other or additional sections or clauses as may be provided in any particular
Supplement).  On each Payment Date under each Supplement for a Series, after
payment of all other amounts then payable to the Indenture Trustee, any
Noteholder or any other Person entitled thereto (except the Issuer), all Excess
Cash Available for Distribution shall be paid to the Indenture Trustee for
payment to the Noteholders under all other Series (each, a "Deficient Series")
of the amount (the "Deficiency Amount") by which the amounts on deposit in the
related Series Account are insufficient for the payment in full of all
Outstanding Obligations then due and payable.  Such Excess Cash Available for
Distribution shall be paid to the Indenture Trustee(s) for each such Deficient
Series in the proportion that the Outstanding Obligations for each such
Deficient Series bears to the aggregate amount of Outstanding Obligations for
all such Deficient Series.  Only after all Deficiency Amounts existing on such
Payment Date have been paid in full shall any such Excess Cash Available for
Distribution be paid to the Issuer.

          Section 402.   PRO RATA INTEREST.  (a)  Each Supplement pursuant to
which a Series of Notes is issued shall identify the Eligible Engines and other
Series Collateral that will be pledged as collateral security for the Notes and
other Obligations for such Series.  All Notes of a particular Series shall be
equally and ratably entitled to the benefits of this Indenture without
preference, priority or distinction, except as provided in the related
Supplement.  All Notes of a particular Class within a Series are and are to be,
to the extent (including any exceptions) provided in this Indenture and the
related Supplement, equally and ratably secured by this Indenture without
preference, priority or distinction on account of the actual time or times of
the authentication or delivery of the Notes so that all Notes of a particular
Series and Class at any time Outstanding shall have the same right, Lien and
preference under this Indenture and shall all be equally and ratably secured
hereby with like effect as if they had all been executed, authenticated and
delivered simultaneously on the date hereof.

          (b)  With respect to each Series of Notes, the execution and delivery
of the related Supplement shall be upon the express condition that if the
conditions specified in Section 701 of this Indenture are met with respect to
such Series of Notes, the security interest and all other estate and rights
granted by this Indenture with respect to such Series of Notes shall cease and
become null and void and all of the property, rights, and interest granted as
security for the Notes of such Series shall revert to and revest in the Issuer
without any other act or formality whatsoever.

          Section 403.   INDENTURE TRUSTEE'S APPOINTMENT AS ATTORNEY-IN-FACT. 
(a)  The Issuer hereby irrevocably constitutes and appoints Indenture Trustee,
and any officer or agent thereof, with full power of substitution, as its true
and lawful attorney-in-fact with full irrevocable power and authority in the
place and stead of the Issuer and in the name of the Issuer or in its own name,
from time to time at Indenture Trustee's discretion, for the purpose


                                          34


of carrying out the terms of this Indenture, to take any and all appropriate
action and to execute and deliver any and all documents and instruments which
may be necessary or desirable to accomplish the purposes of this Indenture;
PROVIDED, HOWEVER, that the Indenture Trustee has no obligation or duty to
determine whether to perfect, file, record or maintain any perfected, filed or
recorded document or instrument in connection with the grant or security
interest in the Collateral hereunder.

          (b)  Except upon the occurrence of an Event of Default, the Indenture
Trustee shall not exercise the power of attorney or any rights granted to the
Indenture Trustee pursuant to this Section 403.  The Issuer hereby ratifies, to
the extent permitted by law, all that said attorney shall lawfully do or cause
to be done by virtue hereof.  The power of attorney granted pursuant to this
Section 403 is a power coupled with an interest and shall be irrevocable until
all Series of Notes are paid and performed in full.

          (c)  The powers conferred on the Indenture Trustee hereunder are
solely to protect Indenture Trustee's interests in the Collateral and shall not
impose any duty upon it to exercise any such powers except as set forth herein. 
The Indenture Trustee shall be accountable only for amounts that it actually
receives as a result of the exercise of such powers and neither it nor any of
its officers, directors, employees, agents or representatives shall be
responsible to the Issuer for any act or failure to act, except for its own
negligence or willful misconduct.

          (d)  The Issuer also authorizes the Indenture Trustee, at any time and
from time to time upon the occurrence of any Event of Default (subject to the
quiet enjoyment rights of any lessee of any Collateral), to (i) communicate in
its own name, or to direct any other Person, including the Servicer or a
replacement Servicer, to communicate with any party to any Contract with regard
to the assignment of the right, title and interest of the Issuer in and under
the Contracts hereunder and other matters relating thereto and (ii) execute, in
connection with the sale of Collateral provided for in Article VIII hereof, any
endorsements, assignments or other instruments of conveyance or transfer with
respect to the Collateral.

          (e)  If the Issuer fails to perform or comply with any of its
agreements contained herein and the Indenture Trustee, with the consent of or at
the direction of the Requisite Global Majority, shall perform or comply, or
otherwise cause performance or compliance, with such agreement, the reasonable
expenses, including attorneys' fees, of Indenture Trustee incurred in connection
with such performance or compliance together with interest thereon at the rate
specified in the related Supplement, shall be payable by the Issuer to the
Indenture Trustee on demand and shall constitute obligations secured hereby.

          Section 404.   RELEASE OF SECURITY INTEREST.  The Indenture Trustee,
at the written direction of the Servicer (which shall be the Administrative
Agent if an Early Amortization Event shall have occurred), shall release from
the security interest created pursuant to the terms of this Indenture, any
Eligible Engine, the related Lease Agreement and any other Related Assets sold
or transferred pursuant to Section 606(a) hereof.  In effectuating


                                          35


such release, the Indenture Trustee shall be entitled to rely on a certificate
of the Servicer (PROVIDED, HOWEVER, that after the occurrence of an Early
Amortization Event, the Administrative Agent in its sole discretion shall be
entitled to deliver such certification) identifying each Eligible Engine, the
related Lease Agreement or other items to be released from the Lien of this
Indenture in accordance with the provisions of this Section 404 accompanied by
an Asset Base Certificate and stating that such release is in compliance with
Sections 404 and 606(a) hereof.

          The Indenture Trustee will, promptly upon receipt of such certificate
from the Servicer or the Administrative Agent and at the Issuer's expense,
execute and deliver to the Issuer, the Seller or the Servicer, as appropriate,
and each Series Enhancer, a non-recourse certificate of release substantially in
the form of Exhibit F hereto and such additional documents and instruments as
that Person may reasonably request (including UCC termination statements and
appropriate filings with the FAA or other Governmental Authority) to evidence
the termination and release from the Lien of this Indenture of such Eligible
Engine, the related Lease Agreement and the other related items of Collateral.

          Section 405.   ADMINISTRATION OF COLLATERAL.  (a)  The Indenture
Trustee hereby acknowledges the appointment by the Issuer of the Servicer to
service and administer the Collateral in accordance with the provisions of the
Servicing Agreement and agrees to provide the Servicer with such documentation,
and to take all such actions, as the Servicer may reasonably request in
accordance with the provisions of the Servicing Agreement or as the Issuer may
request.

          (b)  The Indenture Trustee shall promptly as practicable notify the
Noteholders, each Series Enhancer and the Administrative Agent of any Servicer
Default of which it has prior actual knowledge, and at the direction of the
Requisite Global Majority, shall deliver to the Servicer a Servicer Termination
Notice terminating the Servicer of its responsibilities in accordance with the
terms of the Servicing Agreement.  If the Administrative Agent is unable to
locate and qualify a replacement Servicer within sixty (60) days after the date
of delivery of the Servicer Termination Notice, then the Indenture Trustee may
appoint, or petition a court of competent jurisdiction to appoint, a company
acceptable to the Requisite Global Majority, and whose regular business includes
equipment leasing, as the successor to the Servicer of all or any part of the
responsibilities, duties or liabilities of the Servicer under the Servicing
Agreement, for such portion of the Servicing Fee as the Requisite Global
Majority shall determine in its sole discretion.  The Servicer shall continue to
fulfill its duties and responsibilities as Servicer until such time as its
replacement is appointed and has assumed such responsibilities.  The replaced
Servicer shall not be entitled to receive any compensation for any period after
the effective date of such replacement, but shall be entitled to receive
compensation for services rendered through the effective date of such
replacement except to the extent that it is unable to fulfill such duties
pending the appointment of a replacement Servicer.  If the Servicer is unable to
fulfill such duties pending the appointment of a replacement Servicer, the
Administrative Agent may (but shall not be required to) take such actions which
it is reasonably capable of performing and that have been directed by as the 


                                          36


Requisite Global Majority; PROVIDED, HOWEVER, that as a condition precedent to
taking any such action, the Requisite Global Majority shall provide the
Administrative Agent with (i) indemnification, reasonably satisfactory to the
Administrative Agent, with respect to such actions and (ii) reimbursement of any
out-of-pocket costs incurred by the Administrative Agent in taking such actions
which have been approved by the Requisite Global Majority.  In connection with
the appointment of a replacement Servicer, the Indenture Trustee or
Administrative Agent may, with the written consent of the Requisite Global
Majority, make such arrangements for the compensation of such replacement out of
Collections as the Indenture Trustee, the Administrative Agent and such
replacement Servicer shall agree; PROVIDED, HOWEVER, that no such revised
compensation shall be in excess of the Servicing Fees permitted the Servicer
under the Servicing Agreement and the arrangement for reimbursement of expenses
shall be no more favorable than that set forth in the Servicing Agreement unless
(i) the Indenture Trustee (with the prior written consent of the Requisite
Global Majority) shall approve such higher amounts or (ii) the outgoing Servicer
shall agree to pay, out of its own funds, the replacement Servicer any such
excess compensation and reimbursement; PROVIDED, FURTHER, that in no event shall
either the Indenture Trustee or the Administrative Agent be liable to any
replacement Servicer for the Servicing Fees or any additional amounts (including
expenses and indemnifications) payable to such replacement Servicer, either
pursuant to the Servicing Agreement or otherwise.  The Indenture Trustee and
such successor shall take such action, consistent with the Servicing Agreement,
as shall be necessary to effectuate any such succession.

          (c)  The Indenture Trustee may, and shall if directed by the Requisite
Global Majority, at any time, upon the occurrence of any Servicer Default, after
first notifying the Issuer of its intention to do so, notify Account Debtors of
the Issuer, parties to the Contracts of the Issuer, obligors in respect of
Instruments of the Issuer and obligors in respect of Chattel Paper of the Issuer
that the Accounts and the right, title and interest of the Issuer in and under
such Contracts, Instruments, and Chattel Paper (to the extent related to the
Eligible Engines) have been assigned to Indenture Trustee and that payments
shall be made directly to Indenture Trustee; provided that a replacement
Servicer appointed pursuant to this Section 405 shall unless otherwise directed
by the Requisite Global Majority exercise all of the foregoing rights, and that
pending appointment of such replacement Servicer, the then current Servicer
shall unless otherwise directed by the Requisite Global Majority be permitted to
exercise such rights until the replacement Servicer assumes the responsibility
of the Servicer.  Upon the request of the Requisite Global Majority, the Issuer
or Servicer shall so notify such Account Debtors, parties to such Contracts,
obligors in respect of such Instruments and obligors in respect of such Chattel
Paper.  Upon the occurrence of a Servicer Default, the Indenture Trustee shall
at the direction of the Requisite Global Majority communicate with such Account
Debtors, parties to such Contracts, obligors in respect of such Instruments and
obligors in respect of such Chattel Paper to verify with such parties, to the
Indenture Trustee's satisfaction, the existence, amount and terms of any such
Accounts, Contracts, Instruments or Chattel Paper.

          (d)  Upon the breach of any Engine Representations and Warranties
giving rise to repurchase or substitution obligations of the Seller pursuant to
Section 2.02 of the


                                          37


Contribution and Sale Agreement, the Issuer shall cause the Seller to fully
satisfy such repurchase or substitution obligations and cause to be deposited in
the Trust Account in accordance with the provisions of Section 2.02 of the
Contribution and Sale Agreement, the Warranty Purchase Amounts received from, or
on behalf of, the Seller with respect to such repurchase obligation.  Upon
obtaining actual knowledge or the receipt of notice by the Indenture Trustee
that any repurchase or substitution obligations of the Seller under Section 2.02
of the Contribution and Sale Agreement have arisen, the Indenture Trustee shall
notify the Series Enhancer, if any, for the Series to which the Engines to be
repurchased or substituted are pledged, each Rating Agency and all Noteholders
of the Series to which such Engines are pledged of such event and shall enforce
such repurchase or substitution obligations at the direction of the Control
Party for the affected Series.

          Section 406.   QUIET ENJOYMENT.  The security interest hereby granted
to Indenture Trustee by the Issuer is subject to the rights of any lessee under
the related Lease Agreement so long as such lessee is not in default under the
Lease Agreement therefor and the Servicer under the Servicing Agreement (or the
Indenture Trustee, as provided in Section 405(c)) continues to receive all
amounts payable under the related Contract.

          Section 407.   ACKNOWLEDGMENT.  The Indenture Trustee agrees to
execute any and all acknowledgments that the Issuer or the Seller may require
with respect to the Lessee's right to continued quiet enjoyment of the related
Engine.

Class shall not have any interest in any Series Collateral, Series Account or

          Section 503.   DETERMINATION OF REQUISITE GLOBAL MAJORITY.  A

respect to such new location, it shall have taken at its own cost all action
necessary so that such change of location does not impair the security interest
of the Indenture Trustee in the Collateral, or the perfection of the sale or
contribution to the Issuer of any Eligible Engine, the related Lease Agreements
or any other Related Asset, and shall have delivered to the Indenture Trustee
and each Series Enhancer copies of all filings required in connection therewith

part thereof or any interest therein or the proceeds thereof other than the Lien
created pursuant to this Indenture; and

          (e)  permit the Lien of this Indenture not to constitute a valid first

separate and apart from any other Person: (i) maintain books of account in

                         DISCHARGE OF INDENTURE; PREPAYMENTS

          Section 701.   FULL DISCHARGE.  With respect to each Series of Notes,
upon payment in full of the Outstanding Obligations of such Series, the
Indenture Trustee shall, at the request and at the expense of the Issuer,
execute and deliver to the Issuer such deeds or other instruments as shall be
requisite to evidence the satisfaction and discharge of this Indenture and the
security hereby created with respect to such Series, and to release the Issuer
from its covenants contained in this Indenture and the related Supplement with
respect to such Series in connection with the satisfaction and discharge of the
Indenture, the Indenture Trustee shall be entitled to receive an Opinion of
Counsel stating that such satisfaction and discharge is authorized and
permitted.  All Eligible Engines supporting a Series for which the Outstanding
Obligations of such Series have been paid in full shall be released from the
lien of this Indenture in accordance with Section 404 hereof.

          Section 702.   PREPAYMENT OF NOTES.  (a)  MANDATORY PREPAYMENTS.  At
any time that the Outstanding Obligations of a Series exceed the Asset Base for
such Series as evidenced by the related Asset Base Certificate received by the
Indenture Trustee on any Determination Date, the Issuer shall on each Payment
Date, either (i) acquire, free from all Liens except Permitted Encumbrances,
additional Eligible Engines for such Series in an amount which shall increase
the Asset Base for such Series to the required level, or (ii) prepay the
outstanding principal amount, together with accrued interest thereon, of such
Series of Notes in an aggregate amount equal to such excess, which prepayment
shall be applied in accordance with the provisions of the related Supplement. 
So long as no Early Amortization Event is continuing, any mandatory Prepayment
of one or more Series of Notes pursuant to this Section 702(a) may be
accomplished by a deposit of funds directly into the related Series Account(s).

          (b)  OPTIONAL PREPAYMENTS.  The Issuer may, from time to time, on any
Payment Date and upon at least four (4) Business Days' prior written notice to
the Indenture Trustee, each Series Enhancer and the affected Noteholders, make
an optional prepayment of principal of the Notes of any Series in whole or in
part without premium or penalty except as may be set forth in any Supplement;
PROVIDED, HOWEVER, that any partial prepayment of principal shall be in a
minimum aggregate amount of One Million  Dollars ($1,000,000).  The Issuer shall
promptly confirm any telephonic notice of prepayment in writing.  Any optional
Prepayment of principal made by the Issuer pursuant to this Section 702(b) shall
also include accrued interest to the date of the prepayment on the amount being
prepaid.  So long as no Early Amortization Event is continuing, any optional
prepayment of a Series of Notes pursuant to this Section 702(b) may be
accomplished by a deposit of funds directly into the related Series Account.

          (c)  After an Early Amortization Event, Prepayments will be deposited
into the Trust Account and will be allocated to each Series based on Outstanding
Obligations at the time of the Early Amortization Event.  


                                          47


          Section 703.   UNCLAIMED FUNDS.  In the event that any amount due to
any Noteholder remains unclaimed, the Issuer shall, at its expense, cause to be
published once, in the eastern edition of THE WALL STREET JOURNAL, notice that
such money remains unclaimed.  Any such unclaimed amounts shall not be invested
by the Indenture Trustee (notwithstanding the provisions of Section 303 hereof)
and no additional interest shall accrue on the related Note subsequent to the
date on which such funds were available for distribution to such Noteholder. 
Any such unclaimed amounts shall be held by the Trustee in trust until the
latest of (i) two years after the date of the publication described in the
second preceding sentence, (ii) the date all other registered Noteholders of
such Series shall have received full payment of all principal, interest,
premium, if any, and other sums payable to them on such Notes or the Indenture
Trustee shall hold (and shall have notified the registered Noteholders that it
holds) in trust for that purpose an amount sufficient to make full payment
thereof when due and (iii) the date the Issuer shall have fully performed and
observed all its covenants and obligations contained in this Indenture and the
related Supplement with respect to such Series of Notes.  Thereafter any such
unclaimed amounts shall be paid to the Issuer by the Indenture Trustee on
demand; and thereupon the Indenture Trustee shall be released from all further
liability with respect to such monies, and thereafter the registered Noteholders
in respect of which such monies were so paid to the Issuer shall have no rights
in respect thereof except to obtain payment of such monies from the Issuer.

period set forth above shall be applicable only to the first three payment
defaults pursuant to this clause (B);

          (ii)      default in any material respect in the performance, or
breach in any material respect, of any covenant of the Issuer in this Indenture

with), the related Supplement or if any representation or warranty of the Issuer
made in this Indenture, the related Supplement, or any other Related Documents
or in any certificate or other writing delivered pursuant hereto or thereto or
in connection herewith with respect to or affecting the Notes of such Series

for a period of 60 days after the earlier to occur of (i) actual knowledge of
such default, breach or inaccuracy by the Issuer or (ii) the date on which there
has been given to the Issuer by the Indenture Trustee, or to the Issuer and the
Indenture Trustee by the Series Enhancer or any Noteholder of such Series, a

          (iii)     the entry of a decree or order for relief by a court having
jurisdiction in respect of the Issuer or the Seller in any involuntary case
under any applicable Insolvency Law, or other similar law now or hereafter in

consecutive days;

          (iv)      the commencement by the Issuer or the Seller of a voluntary
case under any applicable Insolvency Law, or other similar law now or hereafter
in effect, or the consent by the Issuer or the Seller, as the case may be, to

custodian, trustee or sequestrator (or other similar official) of the Issuer or
the Seller, as the case may be, or any substantial part of their respective
properties, or the making by the Issuer or the Seller, as the case may be of any

Section 4043 of ERISA) with respect to any Plan, or the occurrence of any event
or condition with respect to a Plan which actually results in the imposition of
a Lien on the Collateral.

          The occurrence of an Event of Default with respect to one Series of
Notes (that has not been waived by the related Control Party) shall constitute
an Event of Default with respect to all other Series of Notes then Outstanding
unless the related Supplement with respect to each such other Series of Notes
shall specifically provide to the contrary.  

          Section 802.   ACCELERATION OF STATED MATURITY; RESCISSION AND
ANNULMENT.  (a)  If an Event of Default under Section 801 occurs and is
continuing, then and in every such case the Control Party for a Series may
declare the Outstanding Obligations for such Series to be due and payable
immediately, by a notice in writing to the Issuer and to the Indenture Trustee
given by such Control Party, and upon any such declaration such Outstanding
Obligations for such Series shall become immediately due and payable.

          (b)  At any time after such a declaration of acceleration has been
made and before a judgment or decree for payment of the money due has been
obtained by the Indenture Trustee as hereinafter in this Article provided, such
Control Party, by written notice to the Issuer and the Indenture Trustee, may
rescind and annul such declaration and its consequences if:

               (i)  the Issuer has paid or deposited with the Indenture Trustee
          a sum sufficient to pay:

                    (A)  all of the installments of interest, premium and
               principal on all Notes which were overdue prior to the date of
               such acceleration;


                                          50


                    (B)  to the extent that payment of such interest is lawful,
               interest at the applicable Overdue Rate on the amounts set forth
               in clause (A) above;

                    (C)  all sums paid or advanced by the Indenture Trustee
               hereunder or the Servicer and the reasonable compensation,
               out-of-pocket expenses, disbursements and advances of the
               Indenture Trustee, its agents and counsel incurred in connection
               with the enforcement of this Indenture; 
                    
                    (D)  all amounts due to any Series Enhancer (if applicable);
               and

                (ii) all Events of Default, other than the nonpayment of the
          principal of or interest on Notes which have become due solely by such
          declaration of acceleration, have been cured or waived as provided in
          Section 813 hereof.

     No such rescission with respect to any Event of Default shall affect any
subsequent Event of Default or impair any right consequent thereon.

          Section 803.   COLLECTION OF INDEBTEDNESS.  The Issuer covenants that,
if an Event of Default occurs and is continuing and a declaration of
acceleration has been made under Section 802 with respect to a Series and not
rescinded, the Issuer will, upon demand of the Indenture Trustee, pay to the
Indenture Trustee, for the benefit of the Noteholders of such Series then
Outstanding and any Series Enhancers of such Series, an amount equal to the sum
of (i) the Outstanding Obligations of such Series including the costs and
out-of-pocket expenses of collection, including the reasonable compensation,
expenses, disbursements and advances of the Indenture Trustee, its agents and
counsel incurred in connection with the enforcement of this Indenture and (ii)
to the extent that the payment of such interest is lawful, interest on the
amount set forth in clause (i) at the applicable Overdue Rate.

          Section 804.   REMEDIES.  If an Event of Default shall occur and be
continuing, the Indenture Trustee, by such officer or agent as it may appoint,
shall notify the applicable Rating Agencies, if any, of such Event of Default
and shall, if instructed by the Control Party of a Series:

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


                                          51


               (ii)   subject to the quiet enjoyment rights of any Lessee under
                      a Lease Agreement, sell, hold or lease the related Series
                      Collateral or any portion thereof or rights or interest
                      therein, at one or more public or private transactions
                      conducted in any manner permitted by law;

               (iii)  institute any Proceedings from time to time for the
                      complete or partial foreclosure of the Lien created by
                      this Indenture and the related Supplement with respect to
                      the related Series Collateral;

               (iv)   institute such other appropriate Proceedings to protect
                      and enforce any other 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; 

               (v)    exercise any remedies of a secured party under the
                      Uniform Commercial Code or any applicable law and take
                      any other appropriate action to protect and enforce the
                      rights and remedies of the Indenture Trustee or the
                      Noteholders of a Series hereunder; and

               (v)    appoint a receiver or a manager over the Issuer or its
                      assets. 

          Section 805.   INDENTURE TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION
OF NOTES.  (a)  In all 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 of the Noteholders of the affected Series, and it shall
not be necessary to make any affected Noteholder a party to any such
Proceedings.

          (b)  All rights of action and claims under this Indenture, the related
Supplement or such 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 trustee of an express trust, and any
recovery whether by judgment, settlement or otherwise shall, after provision for
the payment of the reasonable compensation, expenses, and disbursements incurred
and advances made, by the Indenture Trustee, its agents and counsel, be for the
ratable benefit of the Holders of the Notes of the affected Series, subject to
the subordination of payments among Classes of a particular Series as set forth
in the related Supplement.

          Section 806.   ALLOCATION OF MONEY COLLECTED.  If the Notes of a
Series have been declared due and payable following an Event of Default and such
declaration and its


                                          52


consequences have not been rescinded or annulled, any money collected by the
Indenture Trustee pursuant to this Article or otherwise and any other monies
that may be held or thereafter received by the Indenture Trustee as security for
the Notes of such Series shall be applied, to the extent permitted by law, in
the following order, at the date or dates fixed by the Indenture Trustee:

          FIRST:    To the payment of all amounts due the Indenture Trustee
under Section 905 hereof; and

          SECOND:   To the payment of all management fees or other servicing
fees as more particularly provided in each Supplement and in accordance with the
terms of the related Servicing Agreement; PROVIDED, HOWEVER, that in no event
shall the Servicing Fee then payable pursuant to each Supplement be less than
the Minimum Servicing Fee Percentage of Engine Revenues of the Engines pledged
pursuant to such Supplement.

          THIRD:    Any remaining amounts shall be distributed in accordance
with Section 302 (II) of each Supplement (or such other or additional related
sections or clauses as may be provided in any particular Supplement) hereof but
without duplication of any amounts specified in Section 302(II) of a Supplement
that is also set forth in Section 806 (First) or (Second) above.

          Section 807.   LIMITATION ON SUITS.  Except to the extent provided in
Section 808 hereof, no Noteholder of a Series shall have the right to institute
any Proceeding, 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;

               (ii)      the Control Party of such Series shall have made
          written request to the Indenture Trustee to institute Proceedings 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 security or indemnity against the costs, expenses
          and liabilities to be incurred in compliance with such request (the
          unsecured indemnity of a Rated Institutional Noteholder being deemed
          satisfactory for such purpose);

               (iv)      the Indenture Trustee has, for 30 days after its
          receipt of such notice, request and offer of security or indemnity,
          failed to institute any such Proceeding;  and


                                          53


               (v)       no direction inconsistent with such written request has
          been given to the Indenture Trustee during such 30 day period by the
          Control Party of such Series;

it being understood and intended that no one or more Noteholders shall have any
right in any manner whatsoever by virtue of, or by availing of, any provision of
this Indenture to affect, disturb or prejudice the rights of any other
Noteholder, or to obtain or to seek to obtain priority or preference over any
other Noteholder (except to the extent provided in the related Supplement) or to
enforce any right under this Indenture, except in the manner herein provided and
for the benefit of all Noteholders of a Series.

          Section 808.   UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL AND
INTEREST.  Notwithstanding any other provision of this Indenture, each
Noteholder shall have the right, which is absolute and unconditional, to receive
payment of the principal of and interest on such Note as such principal and
interest becomes due and payable and to institute any Proceeding for the
enforcement of such payment, and such rights shall not be impaired without the
consent of such Holder.

          Section 809.   RESTORATION OF RIGHTS AND REMEDIES.  If the Indenture
Trustee, any Series Enhancer or any Holder has instituted any Proceeding to
enforce any right or remedy under this Indenture or the related Supplement and
such Proceeding has been discontinued or abandoned for any reason, or has been
determined adversely to the Indenture Trustee, any Series Enhancer or to such
Holder, then and in every such case, subject to any determination in such
Proceeding, the Issuer, the Indenture Trustee, such Series Enhancer (if
applicable) and the Holders shall be restored severally and respectively to
their former positions hereunder and thereafter all rights and remedies of the
Indenture Trustee, such Series Enhancer (if applicable) and the Holders shall
continue as though no such Proceeding had been instituted.

          Section 810.   RIGHTS AND REMEDIES CUMULATIVE.  No right or remedy
conferred upon or reserved to the Indenture Trustee, any Series Enhancer (if
applicable) or to the Holders pursuant to this Indenture or any Supplement 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 811.   DELAY OR OMISSION NOT WAIVER.  No delay or omission of
the Indenture Trustee, of any Series Enhancer or of any Holder of any Note to
exercise any right or remedy accruing upon any Event of Default shall impair any
such right or remedy or constitute a waiver of any such Event of Default or an
acquiescence therein.  Every right and remedy given by this Article or by law to
the Indenture Trustee or to the Holders may be


                                          54


exercised from time to time, and as often as may be deemed expedient, by the
Indenture Trustee or by the Holders, as the case may be.

          Section 812.   CONTROL BY THE CONTROL PARTY OF THE AFFECTED SERIES. 
Upon the occurrence of an Event of Default with respect to a Series, the Control
Party of the affected Series 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 that (i) such direction shall not be in conflict with any rule of law
or with this Indenture, including, without limitation, Section 804 hereof,
(ii) such Control Party  has offered to the Indenture Trustee reasonable
security or indemnity against costs, expenses and liabilities which it might
incur in connection therewith as provided in Section 902(iii) hereof, (iii) the
Indenture Trustee may take any other action deemed proper by the Indenture
Trustee which is not inconsistent with such direction.

          Section 813.   WAIVER OF PAST DEFAULTS.  (a)  The Control Party of a
Series may, on behalf of all Noteholders of such Series, waive any past Event of
Default with respect to such Series and its consequences, except an Event of
Default with respect to such Series.

               (i)  in the payment of (x) the principal balance of any Note on
          the Final Payment Date or (y) any required interest payment on any
          Note of any Series on any Payment Date, or

               (ii) in respect of a covenant or provision hereof which cannot be
          modified or amended without the consent of all the Noteholders of all
          Series pursuant to Section 1002 of this Indenture.

          (b)  Upon any such waiver, such Event of Default shall cease to exist
and shall be deemed to have been cured and not to have occurred for every
purpose of this Indenture; PROVIDED, HOWEVER, that no such waiver shall extend
to any subsequent or other Event of Default or impair any right consequent
thereon.

          Section 814.   UNDERTAKING FOR COSTS.  All parties to this Indenture
agree, and each Holder of any Note by acceptance thereof shall be deemed to have
agreed, that any court may in its discretion require, in any suit for the
enforcement of any right or remedy under this Indenture, or in any suit against
the Indenture Trustee for any action taken, suffered or omitted by it as
Indenture Trustee, the filing by any party litigant in such suit of an
undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit, having due regard to the merits and
good faith of the claims or defenses made by such party litigant; PROVIDED,
HOWEVER, that the provisions of this Section shall not apply (i) to any suit
instituted by the Indenture Trustee or any Holder or group of Holders, holding
in the aggregate more than 10% of the aggregate principal balance of the Notes
of all Series then Outstanding, or (ii) to any suit instituted by any Holder for
the enforcement of (x) the payment of interest or principal on


                                          55


any Notes on any Payment Date or (y) the payment of the principal of any Note on
or after the Final Payment Date of such Note.

          Section 815.   WAIVER OF STAY OR EXTENSION LAWS.  The Issuer covenants
(to the extent that it may lawfully do so) that it will 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, which may affect the covenants or the performance of this
Indenture; and 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
will not hinder, delay or impede the execution of any power herein granted to
the Indenture Trustee, but will suffer and permit the execution of every such
power as though no such law had been enacted.

          Section 816.   SALE OF COLLATERAL.  (a)  The power to effect any sale
(a "Sale") of any portion of the Series Collateral pursuant to Section 804
hereof shall not be exhausted by any one or more Sales as to any portion of the
Series Collateral remaining unsold, but shall continue unimpaired until the
entire Series Collateral shall have been sold or the Outstanding Obligations of
the related Series shall have been paid in full.  The Indenture Trustee at the
direction of the Control Party of the related Series may from time to time
postpone any Sale by public announcement made at the time and place of such
Sale.

          (b)  Upon any Sale, whether made under the power of sale hereby given
or under judgment, order or decree in any Proceeding for the foreclosure or
involving the enforcement of this Indenture:  (i) the Indenture Trustee, at the
direction of the Control Party of the related Series, may bid for and purchase
the property being sold, and upon compliance with the terms of such Sale may
hold, retain and possess and dispose of such property in accordance with the
terms of this Indenture; and (ii) the receipt of the Indenture Trustee or of any
officer thereof making such Sale shall be a sufficient discharge to the
purchaser or purchasers at such Sale for its or their purchase money, and such
purchaser or purchasers, and its or their assigns or personal representatives,
shall not, after paying such purchase money and receiving such receipt of the
Indenture Trustee or of such officer therefor, be obliged to see to the
application of such purchase money or be in any way answerable for any loss,
misappropriation or non-application thereof.

          (c)  The Indenture Trustee shall execute and deliver an appropriate
instrument of conveyance transferring its interest in any portion of the
Collateral in connection with a Sale thereof.  In addition, the Indenture
Trustee is hereby irrevocably appointed the agent and attorney-in-fact of the
Issuer to transfer and convey its interest (subject to lessee's rights of quiet
enjoyment) in any portion of the Collateral in connection with a Sale thereof,
and to take all action necessary to effect such Sale.  No purchaser or
transferee at such a Sale 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 monies.

          Section 817.   ACTION ON NOTES.  The Indenture Trustee's right to seek
and recover judgment on the Notes or under this Indenture or any Supplement
shall not be affected


                                          56


by the seeking, obtaining or application of any other relief under or with
respect to this Indenture or any Supplement.  Neither the Lien of this Indenture
nor any rights or remedies of the Indenture Trustee, any Series Enhancer 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 Collateral or upon any of the assets of the Issuer.


                                          57


                                      ARTICLE IX

                           CONCERNING THE INDENTURE TRUSTEE

          Section 901.   DUTIES OF INDENTURE TRUSTEE.  The Indenture Trustee,
prior to the occurrence of an Event of Default with respect to any Series or
after the curing of any Event of Default with respect to any Series which may
have occurred, undertakes to perform such duties and only such duties as are
specifically set forth in this Indenture and the related Supplement.  If an
Event of Default with respect to any Series has occurred and is continuing, the
Indenture Trustee, at the direction of the Control Party of the related Series,
shall exercise such of the rights and powers vested in it by this Indenture and
the related Supplement, and use the same degree of care and skill in its
exercise as a prudent Person would exercise or use under the circumstances in
the conduct of such Person's own affairs.

          The Indenture Trustee, upon receipt of all resolutions, certificates,
statements, opinions, reports, documents, orders or other instruments furnished
to the Indenture Trustee which are specifically required to be furnished
pursuant to any provisions of this Indenture and any applicable Supplement,
shall determine whether they are in the form required by this Indenture and any
applicable Supplement; PROVIDED, HOWEVER, that the Indenture Trustee shall not
be responsible for the accuracy or content of any such resolution, certificate,
statement, opinion, report, document, order or other instrument furnished
pursuant to this Indenture and any applicable Supplement.

          No provision of this Indenture or any Supplement shall be construed to
relieve the Indenture Trustee from liability for its own negligent action, its
own negligent failure to act or its own willful misconduct; PROVIDED, HOWEVER,
that:

          (i)    Prior to the occurrence of an Event of Default and after the
     curing of any Event of Default which may have occurred, the duties and
     obligations of the Indenture Trustee shall be determined solely by the
     express provisions of this Indenture and any Supplements issued pursuant to
     the terms hereof.  The Indenture Trustee shall not be liable except for the
     performance of such duties and obligations as are specifically set forth in
     this Indenture and any Supplements issued pursuant to the terms hereof, and
     no implied covenants or obligations shall be read into this Indenture
     against the Indenture Trustee and, in the absence of bad faith on the part
     of the Indenture Trustee, the Indenture Trustee may conclusively rely, as
     to the truth of the statements and the correctness of the opinions
     expressed therein, upon any Opinion of Counsel, certificates, statements,
     reports, documents, orders, opinions, appraisals, bonds or other documents
     or instruments believed by it to be genuine and to have been signed or
     presented by the proper party or parties and conforming to the requirements
     of this Indenture and any Supplements issued pursuant to the terms hereof;

          (ii)   The Indenture Trustee shall not be liable for an error of
     judgment made in good faith by a Corporate Trust Officer or Corporate Trust
     Officers of the Indenture


                                          58


     Trustee, unless it shall be proved that the Indenture Trustee was negligent
     in ascertaining the pertinent facts; and

          (iii)  The Indenture Trustee shall not be personally liable with
     respect to any action taken, suffered or omitted to be taken by it in good
     faith in accordance with the direction of the Control Party of a Series
     relating to the time, method and place of conducting any Proceeding for any
     remedy available to the Indenture Trustee, or exercising any trust or power
     conferred upon the Indenture Trustee, under this Indenture.

          No provisions of this Indenture shall require the Indenture Trustee to
expend or risk its own funds or otherwise incur any financial liability in the
performance of its duties hereunder, or in the exercise of any of its rights or
powers, if it shall have reasonable grounds for believing that repayment of such
funds or adequate security or indemnity against such risk or liability is not
reasonably assured to it (the unsecured indemnity of (A) a Rated Institutional
Noteholder being deemed satisfactory for such purpose unless the Indenture
Trustee provides written notice to the contrary, or (B) any Series Enhancer, if
applicable (so long as its claims paying ability is rated "AAA" or "Aaa", as
applicable) being deemed satisfactory for such purpose).

          Whether or not therein expressly so provided, every provision of this
Indenture relating to the conduct or affecting the liability of or affording
protection to the Indenture Trustee shall be subject to the provisions of this
Section 901.

          Section 902.   CERTAIN MATTERS AFFECTING THE INDENTURE TRUSTEE.
Except as otherwise provided in Section 901 hereof:

          (i)    The Indenture Trustee may consult with counsel of its selection
     and any advice of such counsel shall be full and complete authorization and
     protection in respect of any action taken or suffered or omitted by it
     hereunder in good faith and in accordance in reliance thereof;

          (ii)   The Indenture Trustee shall be under no obligation to
     institute, conduct or defend any litigation or proceeding hereunder or in
     relation hereto at the request, order or direction of the Control Party of
     a Series, pursuant to the provisions of this Indenture, unless the such
     Control Party shall have offered to the Indenture Trustee reasonable
     security or indemnity against the costs, expenses and liabilities which may
     be incurred therein or thereby (the unsecured indemnity of (A) a Rated
     Institutional Noteholder being deemed satisfactory for such purpose, unless
     the Indenture Trustee provides written notice to the contrary or (B) any
     Series Enhancer if applicable (so long as its claims paying ability is
     rated "AAA" or "Aaa", as applicable) being deemed satisfactory for such
     purpose);


                                          59


          (iii)  The Indenture Trustee shall not be liable for any action taken,
     suffered or omitted by it in good faith and believed by it to be authorized
     or within the discretion or rights or powers conferred upon it by this
     Indenture;

          (iv)   The Indenture Trustee shall not be bound to make any
     investigation into the facts or matters stated in any resolution,
     certificate, statement, instrument, opinion, report, notice, request,
     consent, order, approval, bond or other paper or document, unless requested
     in writing to do so by the Control Party of a Series; PROVIDED, HOWEVER,
     that the Indenture Trustee may require reasonable security or indemnity
     against any cost, expense or liability likely to be incurred in making such
     investigation as a condition to so proceeding (the unsecured indemnity of
     (A) a Rated Institutional Noteholder being deemed satisfactory for such
     purposes unless the Indenture Trustee provides written notice to the
     contrary) or (B) any Series Enhancer (so long as its claims paying ability
     is rated "AAA" or "Aaa," as applicable,) being deemed satisfactory for such
     purpose).  The reasonable expense of any such examination shall be paid, on
     a pro rata basis, by the Noteholders of the applicable Series requesting
     such examination or, if paid by the Indenture Trustee, shall be reimbursed
     by such Noteholders upon demand;

          (v)    The Indenture Trustee may execute any of the trusts or powers
     hereunder or perform any duties hereunder either directly or by or through
     its agents or attorneys, provided that the Indenture Trustee shall not be
     responsible for any misconduct or negligence on the part of any agent or
     attorney appointed by it with due care hereunder; and

          (vi)   The Indenture Trustee shall not be charged with knowledge of
     any Default or Event of Default unless either a Trust Officer of the
     Indenture Trustee shall have actual knowledge or written notice of such
     shall have been given to a Trust Officer of the Indenture Trustee.

          The provisions of this Section 902 shall be applicable to the
Indenture Trustee in its capacity as Indenture Trustee under this Indenture.

          Section 903.   INDENTURE TRUSTEE NOT LIABLE.  (a)  The recitals
contained herein (other than the representations and warranties contained in
Section 911 hereof), in any Supplement and in the Notes (other than the
certificate of authentication on the Notes) shall be taken as the statements of
the Issuer, and the Indenture Trustee assumes no responsibility for their
correctness.  The Indenture Trustee makes no representations as to the validity
or sufficiency of this Indenture, any Supplement, the Notes, the Collateral or
of any related document.  The Indenture Trustee shall not be accountable for the
use or application by the Issuer of any of the Notes or of the proceeds thereof,
or for the use or application of any funds paid to the Issuer or the Servicer in
respect of the Collateral.  The Indenture Trustee will be deemed to have
appointed First Union Capital Markets Corp. to act as Administrative Agent under
the terms of the Administration Agreement without negligence or willful
misconduct.


                                          60



          (b)    The Indenture Trustee shall have no responsibility or liability
for or with respect to the existence or validity of any Engine, the perfection
of any security interest (whether as of the date hereof or at any future time),
the maintenance of or the taking of any action to maintain such perfection, the
validity of the assignment of any portion of the Collateral to the Indenture
Trustee or of any intervening assignment, the compliance by the Seller or the
Servicer with any covenant or the breach by the Seller or the Servicer of any
warranty or representation made hereunder, in any Supplement or in any related
document or the accuracy of such warranty or representation, any investment of
monies in the Trust Account, the Restricted Cash Account or any Series Account
or any loss resulting therefrom (provided that such investments are made in
accordance with the provisions of Section 303 hereof), the acts or omissions of
the Seller or the Servicer taken in the name of the Indenture Trustee, or the
acts or omissions of the Administrative Agent.

          (c)    Except as expressly provided herein or in any Supplement, the
Indenture Trustee shall not have any obligation or liability under any Contract
by reason of or arising out of this Indenture or the granting of a security
interest in such Contract hereunder or the receipt by the Indenture Trustee of
any payment relating to any Contract pursuant hereto, nor shall the Indenture
Trustee be required or obligated in any manner to perform or fulfill any of the
obligations of the Issuer, the Seller or the Servicer under or pursuant to any
Contract, or to make any payment, or to make any inquiry as to the nature or the
sufficiency of any payment received by it, or the sufficiency of any performance
by any party, under any Contract.

          Section 904.   INDENTURE TRUSTEE MAY OWN NOTES.  The Indenture Trustee
in its individual or any other capacity may become the owner or pledgee of Notes
with the same rights it would have if it were not Indenture Trustee; provided
that such transaction shall not result in the disqualification of the Indenture
Trustee for purposes of Rule 3a-7 under the Investment Company Act of 1940.

          Section 905.   INDENTURE TRUSTEE'S FEES AND EXPENSES.  The fees of the
Indenture Trustee shall be paid by the Issuer in accordance with Section 302 of
a related Supplement for a Series.  The Issuer shall indemnify the Indenture
Trustee and each of its officers, directors and employees for, and hold them
harmless against, any loss, liability, damage claim or expense incurred without
negligence or willful misconduct on their part, arising out of or in connection
with the acceptance or administration of this trust, including the costs and
expenses of defending itself both individually and in its representative
capacity against any claim or liability in connection with the exercise or
performance of any of its powers or duties hereunder (including, but not limited
to, loss, liability, damage, claim or expense incurred by reason of the
appointment of First Union Capital Markets Corp. to act as Administrative
Agent).

          The obligations of the Issuer under this Section 905 to compensate the
Indenture Trustee, to pay or reimburse the Indenture Trustee for expenses,
disbursements and advances and to indemnify and hold harmless, the Indenture
Trustee shall constitute Outstanding


                                          61


Obligations hereunder and shall survive the resignation or removal of the
Indenture Trustee and the satisfaction and discharge of this Indenture.

          When the Trustee incurs expenses or renders services in connection
with an Event of Default specified in Section 801(iii) or Section 801(iv), the
expenses and the compensation for the services are intended to constitute
expenses of administration under any bankruptcy law.

          Section 906.   ELIGIBILITY REQUIREMENTS FOR INDENTURE TRUSTEE.  The
Indenture Trustee hereunder shall at all times be a national banking association
or a corporation, organized and doing business under the laws of the United
States of America or any State, and authorized under such laws to exercise
corporate trust powers.  In addition, the Indenture Trustee or its parent
corporation shall at all times (i) have a combined capital and surplus of at
least $250,000,000, (ii) be subject to supervision or examination by Federal or
state authority and (iii) have a long-term unsecured senior debt rating of "A-2"
or better by Moody's Investors Service, Inc. or a long-term unsecured senior
debt rating of "A" by Standard & Poor's Rating Services and short-term unsecured
senior debt rating of "P-1" or better by Moody's Investors Service, Inc. or a
short-term unsecured senior debt rating of "A-2" by Standard & Poor's Rating
Services.  If such corporation publishes reports of condition at least annually,
pursuant to law or to the requirements of such supervising or examining
authority, then, for the purposes of this Section 906, 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.  In
case at any time the Indenture Trustee shall cease to be eligible in accordance
with the provisions of this Section, the Indenture Trustee shall resign
immediately in the manner and with the effect specified in Section 907 hereof.
In lieu of the foregoing eligibility requirements for the Indenture Trustee, The
Bank of New York shall be an eligible Indenture Trustee.

          Section 907.   RESIGNATION AND REMOVAL OF INDENTURE TRUSTEE.  The
Indenture Trustee may at any time resign and be discharged from the trusts
hereby created by giving written notice thereof to the Issuer, the Servicer,
each Series Enhancer if applicable and the Noteholders.  Upon receiving such
notice of resignation, the Issuer shall promptly appoint a successor trustee by
written instrument, in duplicate, one copy of which instrument shall be
delivered to the resigning Indenture Trustee each Series Enhancer if applicable,
and one copy to the successor Indenture Trustee.  If no successor Indenture
Trustee shall have been so appointed and have accepted appointment within 30
days after the giving of such notice of resignation, the Requisite Global
Majority may appoint a successor trustee or, if it does not do so within 30 days
thereafter, the resigning Indenture Trustee, with the consent of each Series
Enhancer, may petition any court of competent jurisdiction for the appointment
of a successor trustee, which successor trustee shall meet the eligibility
standards set forth in Section 906.

          If at any time the Indenture Trustee shall cease to be eligible in
accordance with the provisions of Section 906 hereof and shall fail to resign
after written request therefor by the Issuer, any Series Enhancer if applicable
or the Servicer, or if at any time the Indenture Trustee shall become incapable
of acting, or shall be adjudged a bankrupt or insolvent, or a


                                          62


receiver of the Indenture Trustee or of its property shall be appointed, or any
public officer shall take charge or control of the Indenture Trustee or of its
property or affairs for the purpose of rehabilitation, conservation or
liquidation, then the Issuer shall remove the Indenture Trustee and appoint a
successor Indenture Trustee by written instrument, in duplicate, one copy of
which instrument shall be delivered to the Indenture Trustee so removed and one
copy to the successor Indenture Trustee.

          Any resignation or removal of the Indenture Trustee and appointment of
a successor trustee pursuant to any of the provisions of this Section shall
become effective upon acceptance of appointment by the successor trustee as
provided in Section 908 hereof.

          Section 908.   SUCCESSOR INDENTURE TRUSTEE.  Any successor Indenture
Trustee appointed as provided in Section 907 hereof shall execute, acknowledge
and deliver to the Issuer and to its predecessor Indenture Trustee an instrument
accepting such appointment hereunder, and thereupon the resignation or removal
of the predecessor Indenture Trustee shall become effective and such successor
Indenture Trustee, without any further act, deed or conveyance, shall become
fully vested with all the rights, powers, duties and obligations of its
predecessor hereunder, with like effect as if originally named as Indenture
Trustee herein.  The predecessor Indenture Trustee shall deliver to the
successor Indenture Trustee all documents relating to the Collateral, if any,
delivered to it, together with any amount remaining in the Trust Account,
Restricted Cash Account and any other Series Accounts.  In addition, the
predecessor Indenture Trustee and, upon request of the successor Indenture
Trustee, the Issuer shall execute and deliver such instruments and do such other
things as may reasonably be required for more fully and certainly vesting and
confirming in the successor Indenture Trustee all such rights, powers, duties
and obligations.

          No successor Indenture Trustee shall accept appointment as provided in
this Section unless at the time of such acceptance such successor Indenture
Trustee shall be eligible under the provisions of Section 906 hereof and shall
be acceptable to the Requisite Global Majority.

          Upon acceptance of appointment by a successor Indenture Trustee as
provided in this Section, the Issuer shall mail notice of the succession of such
Indenture Trustee hereunder to all Noteholders at their addresses as shown in
the registration books maintained by the Indenture Trustee.  If the Issuer fails
to mail such notice within 10 days after acceptance of appointment by the
successor Indenture Trustee, the successor Indenture Trustee shall cause such
notice to be mailed at the expense of the Issuer.

          Section 909.   MERGER OR CONSOLIDATION OF INDENTURE TRUSTEE.  Any
corporation into which the Indenture Trustee may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Indenture Trustee shall be a party, or
any corporation succeeding to the business of the Indenture Trustee, shall be
the successor of the Indenture Trustee hereunder, provided such corporation
shall be eligible under the provisions of Section 906 hereof, without the
execution


                                          63


or filing of any paper or any further act on the part of any of the parties
hereto, anything herein to the contrary notwithstanding.

          Section 910.   SEPARATE INDENTURE TRUSTEES, CO-INDENTURE TRUSTEES AND
CUSTODIANS.  If the Indenture Trustee is not capable of acting outside the
United States, it shall have the power from time to time to appoint one or more
Persons or corporations to act either as co-trustees jointly with the Indenture
Trustee, or as separate trustees, or as custodians, for the purpose of holding
title to, foreclosing or otherwise taking action with respect to any of the
Collateral, when such separate trustee or co-trustee is necessary or advisable
under any applicable laws or for the purpose of otherwise conforming to any
legal requirement, restriction or condition in any applicable jurisdiction.  The
separate trustees, co-trustees, or custodians so appointed shall be trustees,
co-trustees, or custodians for the benefit of all Noteholders and shall have
such powers, rights and remedies as shall be specified in the instrument of
appointment; PROVIDED, HOWEVER, that no such appointment shall, or shall be
deemed to, constitute the appointee an agent of the Indenture Trustee.  The
Issuer shall join in any such appointment, but such joining shall not be
necessary for the effectiveness of such appointment.

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


(i)  all powers, duties, obligations and rights conferred upon the Indenture
Trustee in respect of the receipt, custody and payment of moneys shall be
exercised solely by the Indenture Trustee;

          (ii)   all other 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,
     co-trustee, or custodian jointly, 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 Collateral or any portion thereof in
     any such jurisdiction) shall be exercised and performed by such separate
     trustee, co-trustee or custodian;

          (iii)  no trustee or custodian hereunder shall be personally liable by
     reason of any act or omission of any other trustee or custodian hereunder;
     and

          (iv)   the Issuer or the Indenture Trustee may at any time accept the
     resignation of or remove any separate trustee, co-trustee or custodian so
     appointed by it or them if such resignation or removal does not violate the
     other terms of this Indenture.


                                          64


          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, co-trustee, or custodian shall refer to this
Indenture and the conditions of this Article.  Each separate trustee and
co-trustee, upon its acceptance of the trusts conferred, shall be vested with
the estates or property specified in its instrument of appointment, either
jointly with the 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.  Every such instrument
shall be furnished to the Indenture Trustee and each Series Enhancer.

          Any separate trustee, co-trustees, or custodian may, at any time,
constitute 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, co-trustee, or custodian 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 or custodian.

          No separate trustee, co-trustee or custodian hereunder shall be
required to meet the terms of eligibility as a successor trustee under Section
906 hereof and no notice to Noteholders of the appointment thereof shall be
required under Section 908 hereof.

          The Indenture Trustee agrees to instruct the co-trustees, if any, to
the extent necessary to fulfill the Indenture Trustee's obligations hereunder.

          Section 911.   REPRESENTATIONS, WARRANTIES AND COVENANTS.  The
Indenture Trustee hereby represents, warrants and covenants as of the Effective
Date of each Series that:

          (a)    ORGANIZATION AND GOOD STANDING.  The Indenture Trustee is a New
York banking corporation duly organized, validly existing and in good standing

Notes has been duly authorized by the Indenture Trustee by all necessary
corporate action;

          (c)    BINDING OBLIGATIONS.  This Indenture and each Supplement,
assuming due authorization, execution and delivery by the Issuer, constitutes
the legal, valid and binding obligations of the Indenture Trustee, enforceable
against the Indenture Trustee in accordance with its terms, except that (i) such
enforcement may be subject to bankruptcy, insolvency,


                                          65


reorganization, moratorium or other similar laws (whether statutory, regulatory
or decisional) now or hereafter in effect relating to creditors' rights
generally and the rights of trust companies in particular and (ii) the remedy of
specific performance and injunctive and other forms of equitable relief may be
subject to certain equitable defenses and to the discretion of the court before
which any proceeding therefor may be brought, whether in a proceeding at law or
in equity;

          (d)    NO VIOLATION.  The performance by the Indenture Trustee of its
obligations under this Indenture and each Supplement will not conflict with,
result in any breach of any of the terms and provisions of, or constitute (with
or without notice, lapse of time or both) a default under, the charter documents
or bylaws of the Indenture Trustee;

          (e)    NO PROCEEDINGS.  There are no proceedings or investigations to
which the Indenture Trustee is a party pending, or, to the knowledge of the
Indenture Trustee, threatened, before any court, regulatory body, administrative
agency or other tribunal or Governmental Authority (A) asserting the invalidity
of this Indenture or the Notes, (B) seeking to prevent the issuance of the Notes
or the consummation of any of the transactions contemplated by this Indenture or
(C) seeking any determination or ruling that would materially and adversely
affect the performance by the Indenture Trustee of its obligations under, or the
validity or enforceability of, this Indenture or the Notes; and

          (f)    APPROVALS.  Neither the execution or delivery by the Indenture
Trustee of this Indenture nor the consummation of the transactions by the
Indenture Trustee contemplated hereby requires the consent or approval of, the
giving of notice to, the registration with or the taking of any other action
with respect to any Governmental Authority under any existing federal or State
of New York law governing the banking or trust powers of the Indenture Trustee.

          (g)    SECURITIES ACCOUNTS.  (i) The Indenture Trustee is a bank which
regularly accepts in the ordinary course of its business securities of the same
type as the applicable Collateral as a custodial service for its customers and
maintains in the State of New York deposit accounts and securities accounts for
its customers; (ii) The Indenture Trustee will at all times be acting solely in
the capacity of a Securities Intermediary with respect to items of Collateral
identified on its books and records; (iii) The Indenture Trustee will maintain
its offices and books and records with respect to its securities accounts in the
State of New York; (iv) The Indenture Trustee will at all times maintain an
account with and be a member of The Federal Reserve Bank; and (v) The Indenture
Trustee will act in accordance with, and fulfill its obligations under the terms

receives in accordance thereunder to the appropriate Securities Account.

          Section 912.   INDENTURE TRUSTEE OFFICES.  The Indenture Trustee shall
maintain in the State of New York an office or offices or agency or agencies
where Notes may be


                                          66


surrendered for registration of transfer or exchange, which office shall
initially be located at 101 Barclay Street, New York, New York 10286, and shall
promptly notify the Issuer, the Servicer and the Noteholders of any change of
such location.

          Section 913.   NOTICE OF EVENT OF DEFAULT.  If the Indenture Trustee
shall have actual knowledge of an Event of Default with respect to any Series,
the Indenture Trustee shall give prompt written notice thereof to the
Noteholders and any Series Enhancer of such Series.  For all purposes of this
Indenture, in the absence of actual knowledge by a Corporate Trust Officer of
the Indenture Trustee, the Indenture Trustee shall not be deemed to have actual
knowledge of any Event of Default unless notified in writing thereof by the
Issuer, the Seller, the Servicer, any Series Enhancer or any Noteholder, and
such notice references the applicable Series of Notes generally, the Issuer,
this Indenture or the applicable Supplement.

sale, enforceability, non-consolidation and security interest perfection issues;
and

                 (vi)    such other conditions as shall be specified in the

          (2)    The occurrence of an additional Early Amortization Event as
                 specified in the related Supplement for any Series.

          The occurrence of an Early Amortization Event with respect to one

constitute an Early Amortization Event with respect to all other Series of Notes
then Outstanding unless waived by the Control Party for such other Series or
unless the related Supplement with respect to each such other Series of Notes

                 (iv)    a statement as to whether, in the opinion of each such
          individual, such condition or covenant has been complied with.

          Section 1302.  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 as to other matters, and any such Person may certify
or give an opinion as to such matters in one or several documents.


                                          75


          (b)    Any certificate or opinion may be based, insofar as it relates

          (c)    Where any Person is required to make, give or execute two or
more applications, requests, consents, certificates, statements, opinions or

authorization, direction, notice, consent, waiver or other action provided by
this Indenture or any Supplement to be given or taken by Holders may be

similar tenor signed by such Holders in person or by an agent duly appointed in
writing, (ii) evidenced by the written consent or direction of Holders of the
specified percentage of the principal amount of the Notes, or (iii) evidenced by
a combination of such instrument or instruments; and, except as herein otherwise
expressly provided, such action shall become effective when such instrument or
instruments and record are delivered to the Indenture Trustee and, where it is
hereby expressly required, to the Issuer.  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 conclusive in favor of the Indenture Trustee and
the Issuer, if made in the manner provided in this Section.

          (b)    The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgements of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof.  Where
such execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his authority.  The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may also be proved
in any other manner which 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 Act of the Holder of any Note shall bind every future Holder of
the same Note and the Holder of every Note issued upon the registration of
transfer thereof or in exchange therefor or 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 1304.  INSPECTION.  (a)  Upon reasonable request, the Issuer
agrees that it shall make available to any representative of the Indenture
Trustee, any Series Enhancer (if applicable) or the Administrative Agent and
their duly authorized representatives, attorneys or


                                          76


accountants, for inspection and copying its books of account, records and
reports relating to the Eligible Engines, the related Lease Agreements and the
other items of Collateral, all in the format which the Servicer uses for its own
operations.  Such inspections shall be conducted during normal business hours
and shall not unreasonably disrupt the Servicer's business.  Any expense
incident to the reasonable exercise by the Indenture Trustee, the Administrative
Agent, each Series Enhancer (if applicable) or any Noteholder of any right under
this Section shall be borne by the Person exercising such right unless an Event
of Default shall have occurred and then be continuing in which case such
expenses shall be borne by the Issuer.

                 (b)     The Issuer also agrees (i) to make available on a
reasonable basis  upon reasonable request to the Indenture Trustee,
Administrative Agent, any Series Enhancer (if applicable) or any prospective
owner a Servicing Officer for the purpose of answering reasonable questions
respecting recent developments affecting the Issuer and (ii) to instruct the
Servicer to allow the Indenture Trustee, Administrative Agent, any Series
Enhancer (if applicable) or any prospective owner to inspect the Servicer's
facilities upon reasonable request during normal business hours.

          Section 1305.  LIMITATION OF RIGHTS.  Except as expressly set forth in
this Indenture, this Indenture shall be binding upon the Issuer, the Noteholders
and their respective successors and permitted assigns and shall not inure to the
benefit of any Person other than the parties hereto, the Noteholders and the
Servicer as provided herein.  Notwithstanding the previous sentence, the parties
hereto, the Seller and the Servicer acknowledge that any Series Enhancer (if
applicable) for a Series of Notes is an express third party beneficiary hereof
entitled to enforce its rights hereunder as if actually a party hereto.

          Section 1306.  SEVERABILITY.  If any provision of this Indenture is
held to be in conflict with any applicable statute or rule of law or is
otherwise held to be unenforceable for any reason whatsoever, such circumstances
shall not have the effect of rendering the provision in question inoperative or
unenforceable in any other case or circumstance, or of rendering any other
provision or provisions herein contained invalid, inoperative, or unenforceable
to any extent whatsoever.

          The invalidity of any one or more phrases, sentences, clauses or
