or interest hereby assigned to anyone other than the Trustee and that it will

                  IT IS HEREBY COVENANTED AND AGREED by and among the parties
hereto as follows:


                                   ARTICLE I


                                   DEFINITIONS


                  Section 1.01 Certain Definitions. Unless the context otherwise
requires, all capitalized terms used herein and not otherwise defined shall have
the meanings set forth in Appendix A hereto for all purposes of this Indenture.
All references to articles, sections, clauses, schedules, exhibits, annexes and
appendices in this Indenture are to articles, sections, clauses, schedules,
exhibits, annexes and appendices in and to this Indenture unless otherwise
indicated.


                                   ARTICLE II


                               THE EQUIPMENT NOTES


                  Section 2.01 Form of Equipment Notes. (a) The Equipment Notes
and the Trustee's certificate of authentication with respect thereto shall be
substantially in the form annexed hereto as Exhibit B. The Equipment Notes may
have such appropriate insertions, omissions, substitutions and other variations
as are required or permitted by this Indenture and may have letters, notations,
legends or endorsements required by law, stock exchange agreements to which the
Company is subject, or usage. Any portion of the text of any Equipment Note may
be set forth on the reverse thereof, with an appropriate reference thereto on






                                       3











the face of the Equipment Note. The Company shall approve the form of the
Equipment Notes and any notation, legend or endorsement on the Equipment Notes.
Each Equipment Note shall be dated the date of its authentication.


                  The terms and provisions contained in the form of the
Equipment Notes annexed hereto as Exhibit B shall constitute, and are hereby
expressly made, a part of this Indenture. Each of the Company and the Trustee,
by its execution and delivery of this Indenture, expressly agrees to the terms
and provisions of the Equipment Notes applicable to it and to be bound thereby.


                  The Equipment Notes shall be typed, printed, lithographed or
engraved or produced by any combination of these methods or may be produced in
any other manner determined by the officers executing such Equipment Notes, as
evidenced by their execution of such Equipment Notes.


                  Section 2.02 Execution, Authentication and Denominations. The
Equipment Notes shall be executed by an Officer of the Company authorized to
execute Equipment Notes, by facsimile or manual signature, in the name and on
behalf of the Company.


                  If an officer whose signature is on an Equipment Note no
longer holds that office at the time the Trustee authenticates the Equipment
Note, the Equipment Note shall be valid nevertheless.


                  An Equipment Note shall not be valid until the Trustee
manually signs the certificate of authentication on the Equipment Note. The
signature shall be conclusive evidence that the Equipment Note has been
authenticated under this Indenture.


                  At any time and from time to time after the execution of this
Indenture, the Trustee shall, upon receipt of a Company Order, authenticate for
original issue Equipment Notes in the aggregate principal amount specified in
such Company Order. Such Company Order shall specify the amount of Equipment
Notes to be authenticated and the date on which the issue of Equipment Notes is
to be authenticated.


                  Section 2.03 Registrar and Paying Agent. The Company shall
maintain an office or agency where Equipment Notes may be presented for
registration of transfer or for exchange (the "Registrar"), an office or agency
where Equipment Notes may be presented for payment (the "Paying Agent"), and an
office or agency where notices and demands to or upon the Company in respect of
the Equipment Notes and this Indenture may be served. The Company shall cause
the Registrar to keep a register of the Equipment Notes and of their transfer
and exchange (the "Equipment Note Register"). The Company may have one or more
additional Paying Agents.


                  The Company shall enter into an appropriate agency agreement
with any Agent not a party to this Indenture. The agreement shall implement the
provisions of this Indenture that relate to such Agent. The Company shall give
prompt written notice to the Trustee of the name and address of any such Agent
and any change in the address of such Agent. If the Company fails to maintain a
Registrar, Paying Agent and/or agent for service of notices and demands, the
Trustee shall act as such Registrar, Paying Agent and/or agent for service of
notices and demands 






                                       4











for so long as such failure shall continue. The Company may remove any Agent
upon written notice to such Agent and the Trustee; provided that no such removal
shall become effective until (i) the acceptance of an appointment by a successor
Agent to such Agent as evidenced by an appropriate agency agreement entered into
by the Company and such successor Agent and delivered to the Trustee or (ii)
notification to the Trustee that the Trustee shall serve as such Agent until the
appointment of a successor Agent in accordance with clause (i) of this proviso.
The Company or any Affiliate of the Company may act as Paying Agent, Registrar,
and/or agent for service of notice and demands. The Company shall initially act
as the Paying Agent.


                  The Company initially appoints the Trustee as Registrar,
Paying Agent and authenticating agent. If, at any time, the Trustee is not the
Registrar, the Registrar shall make available to the Trustee on or before each
Interest Payment Date and at such other times as the Trustee may reasonably
request, the names and addresses of the Holders as they appear in the Equipment
Note Register.


                  Section 2.04 Paying Agent to Hold Money in Trust. The Company
shall require each Paying Agent, if any, other than the Trustee to agree in
writing that such Paying Agent shall hold in trust for the benefit of the
Holders or the Trustee all money held by the Paying Agent for the payment of
principal of, premium, if any, or interest on the Equipment Notes (whether such
money has been paid to it by the Company or the Guarantor on the Equipment
Notes), and that such Paying Agent shall promptly notify the Trustee of any
default by the Company (or the Guarantor on the Equipment Notes) in making any
such payment. The Company at any time may require a Paying Agent to pay all
money held by it to the Trustee and account for any funds disbursed, and the
Trustee may at any time during the continuance of any payment default, upon
written request to a Paying Agent, require such Paying Agent to pay all money
held by it to the Trustee and to account for any funds disbursed. Upon doing so,
the Paying Agent shall have no further liability for the money so paid over to
the Trustee. If the Company or any Subsidiary of the Company or any Affiliate of
any of them acts as Paying Agent, it will, on or before each due date of any
principal of, premium, if any, or interest on the Equipment Notes, segregate and
hold in a separate trust fund for the benefit of the Holders a sum of money
sufficient to pay such principal, premium, if any, or interest so becoming due
until such sum of money shall be paid to such Holders or otherwise disposed of
as provided in this Indenture, and will promptly notify the Trustee of its
action or failure to act as required by this Section 2.04.


                  Section 2.05 Transfer and Exchange. The Equipment Notes are
issuable only in registered form. A Holder may transfer an Equipment Note by
written application to the Registrar stating the name of the proposed transferee
and otherwise complying with the terms of this Indenture. No such transfer shall
be effected until, and such transferee shall succeed to the rights of a Holder
only upon registration of the transfer by the Registrar in the Equipment Note
Register. Prior to the registration of any transfer by a Holder as provided
herein, the Company, the Trustee, and any agent of the Company or the Trustee
shall treat the Person in whose name the Equipment Note is registered as the
owner thereof for all purposes and none of the Company, the Trustee, or any such
agent shall be affected by notice to the contrary. When Equipment Notes are
presented to the Registrar with a request to register the transfer or to
exchange them for an equal principal amount of Equipment Notes of other
authorized denominations, the Registrar shall register the transfer or make the
exchange as requested if its requirements for such transactions are met. To
permit registrations of transfers and exchanges in accordance with 






                                       5











the terms, conditions and restrictions hereof, the Company shall execute and the
Trustee shall authenticate Equipment Notes. No service charge shall be made to
any Holder for any registration of transfer or exchange or redemption of the
Equipment Notes, but the Company may require payment of a sum sufficient to
cover any transfer tax or similar governmental charge payable in connection
therewith (other than any such transfer taxes or other similar governmental
charge payable upon transfers or exchanges pursuant to Section 2.12 or 8.05).


                  Section 2.06 Replacement Equipment Notes. If (i) a mutilated
Equipment Note is surrendered to the Trustee or the Trustee receives evidence to
its satisfaction of the destruction, loss or theft of any Equipment Note, and
(ii) there is delivered to the Company and the Trustee such security or
indemnity as may be required by them to hold each of them harmless, then, in the
absence of notice to the Company, the Registrar or the Trustee that such
Equipment Note has been acquired by a protected purchaser, the Company shall
execute and upon its request the Trustee shall authenticate and deliver, in
exchange for or in lieu of any such mutilated, destroyed, lost or stolen
Equipment Note, a replacement Equipment Note of like tenor and amount; provided,
however, that if any such mutilated, destroyed, lost or stolen Equipment Note
has become or is about to become due and payable, the Company, in its
discretion, may pay such Equipment Note instead of issuing a new Equipment Note
in replacement thereof.


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


                  Every replacement Equipment Note issued pursuant to this
Section in replacement of any mutilated, destroyed, lost or stolen Equipment
Note shall constitute an original additional contractual obligation of the
Company, whether or not the mutilated, destroyed, lost or stolen Equipment Note
shall be at any time enforceable by anyone, and shall be entitled to all the
benefits of this Indenture equally and proportionately with any and all other
Equipment Notes duly issued hereunder.


                  Section 2.07 Outstanding Equipment Notes. Equipment Notes
outstanding at any time are all Equipment Notes that have been authenticated by
the Trustee except for those cancelled by it, those delivered to it for
cancellation and those described in this Section 2.07 as not outstanding.


                  If an Equipment Note is replaced pursuant to Section 2.06, it
ceases to be outstanding unless and until the Trustee and the Company receive
proof reasonably satisfactory to them that the replaced Equipment Note is held
by a protected purchaser.


                  An Equipment Note does not cease to be outstanding because the
Company or one of its Affiliates holds such Equipment Note; provided, however,
that, in determining whether the Holders of the requisite principal amount of
the outstanding Equipment Notes have given any request, demand, authorization,
direction, notice, consent or waiver hereunder, Equipment Notes owned by the
Company or any other obligor upon the Equipment Notes or any Affiliate of the
Company or of such other obligor shall be disregarded and deemed not to be
outstanding, except that, in determining whether the Trustee shall be protected
in relying upon any such request, 






                                       6











demand, authorization, direction, notice, consent or waiver, only Equipment
Notes which a Responsible Officer of the Trustee knows to be so owned shall be
so disregarded. Equipment Notes so owned which have been pledged in good faith
may be regarded as outstanding if the pledgee establishes to the satisfaction of
the Trustee the pledgee's right so to act with respect to such Equipment Notes
and that the pledgee is not the Company or any other obligor upon the Equipment
Notes or any Affiliate of the Company or of such other obligor.


                  Section 2.08 Cancellation. The Company at any time may deliver
to the Trustee for cancellation any Equipment Notes previously authenticated and
delivered hereunder which the Company may have acquired in any manner
whatsoever. The Registrar and the Paying Agent shall forward to the Trustee any
Equipment Notes surrendered to them for registration of transfer, exchange,
purchase or payment. The Trustee shall cancel all Equipment Notes surrendered
for registration of transfer, exchange, purchase, payment or cancellation and
shall return all such Equipment Notes to the Company. The Company shall not
issue Equipment Notes to replace Equipment Notes it has paid in full or
delivered to the Trustee for cancellation.


                  Section 2.09 Application of Payments to Principal Amount and
Interest. In the case of each Equipment Note, each payment of principal thereof
and premium, if any, and interest thereon shall be applied, first, to the
payment of accrued but unpaid interest on such Equipment Note then due
thereunder (as well as any interest on any overdue principal amount) and (to the
extent permitted by law) any overdue premium, if any, any overdue interest and
any other overdue amounts thereunder to the date of such payment, second, to the
payment of any premium then due thereon, and third, to the payment of the
principal amount of such Equipment Note then due thereunder (which, in the case
of any partial redemption pursuant to Section 2.12, shall be applied toward the
pro rata reduction of all remaining installments of principal on such Equipment
Note).


                  Section 2.10 Termination of Interest in Indenture Estate. A
Holder shall have no further interest in, or other right with respect to, the
Indenture Estate when and if the principal amount of and interest on all
Equipment Notes held by such Holder and all other sums payable to such Holder
hereunder and under such Equipment Notes shall have been paid in full.


                  Section 2.11 Equally and Ratably Secured. All Equipment Notes
at any time outstanding under this Indenture shall be equally and ratably
secured hereby without preference, priority or distinction on account of the
date or dates, the actual time or times of the issue or maturity of such
Equipment Notes so that all Equipment Notes at any time issued and outstanding
hereunder shall have the same rights and preferences, and be entitled to the
same benefits provided by the Liens created, under and by virtue of this
Indenture.


                  Section 2.12 Redemption; Notice of Redemption. (a) The Company
may, at its option, on not less than 30 (and no more than 60) days' notice to
the Trustee, redeem on any date the outstanding Equipment Notes in whole or in
part, at a redemption price equal to the greater of (1) 100% of the principal
amount of the Equipment Notes to be redeemed, and (2) as determined by the
Quotation Agent, the sum of the present values of the remaining scheduled
payments of principal and interest in respect of the Equipment Notes to be
redeemed (not including any portion of those payments of interest accrued as of
the date of redemption) discounted to the date of redemption on a semiannual
basis (assuming a 360-day year consisting of twelve 30-day 






                                       7











months) at the Adjusted Treasury Rate plus 25 basis points, plus, in each case,
accrued interest to the date of redemption.


                  "Adjusted Treasury Rate" means, with respect to any redemption
date, the rate per year equal to the semiannual equivalent yield to maturity of
the Comparable Treasury Issue, assuming a price for the Comparable Treasury
Issue (expressed as a percentage of its principal amount) equal to the
Comparable Treasury Price for that redemption date.


                  "Comparable Treasury Issue" means the United States Treasury
security selected by the Quotation Agent as having a maturity comparable to the
remaining term of the Equipment Notes to be redeemed that would be utilized, at
the time of selection and in accordance with customary financial practice, in
pricing new issues of corporate debt securities of comparable maturity to the
remaining term of those Equipment Notes.


                  "Comparable Treasury Price" means, with respect to any
redemption date, (i) the average of the Reference Treasury Dealer Quotations for
that redemption date, after excluding the highest and lowest Reference Treasury
Dealer Quotations, or (ii) if the Trustee obtains fewer than three Reference
Treasury Dealer Quotations, the average of all Reference Treasury Dealer
Quotations so received.


                  "Quotation Agent" means the Reference Treasury Dealer
appointed by the Company.


                  "Reference Treasury Dealer" means (1) J.P. Morgan Securities
Inc. and its successors, provided, however, that if the foregoing shall cease to
be a primary U.S. Government securities dealer in New York City (a "Primary
Treasury Dealer"), the Company shall substitute another Primary Treasury Dealer,
and (2) any other Primary Treasury Dealer selected by the Company.


                  "Reference Treasury Dealer Quotations" means, with respect to
each Reference Treasury Dealer and any redemption date, the average, as
determined by the Reference Treasury Dealer, of the bid and asked prices for the
Comparable Treasury Issue (expressed in each case as a percentage of its
principal amount) quoted in writing by that Reference Treasury Dealer at 5:00
p.m., New York City time, on the third Business Day preceding that redemption
date.


                  Upon the redemption of any Equipment Notes pursuant to this
Section 2.12(a), the Trustee shall, in accordance with Section 11.01(a), release
from the Lien of this Indenture the Items of Equipment specified by the Company
in a Company Order having an aggregate Fair Value as determined by the Company
equal to or less than the product obtained by multiplying the aggregate Fair
Value of all Items of Equipment subject to the Lien of this Indenture by a
fraction, the numerator of which shall be the aggregate unpaid principal amount
of the Equipment Notes so redeemed and the denominator of which shall be the
aggregate unpaid principal amount of all Equipment Notes outstanding immediately
prior to such redemption.


                  (b) In connection with an Event of Loss (unless the Company
shall have elected the option set forth in Section 9.11(a)(i) with respect
thereto), the Company shall, on or before the relevant Loss Redemption Date (as
defined in Section 9.11(a)), redeem a principal amount of the Equipment Notes
equal to the product obtained by multiplying the aggregate 






                                       8











unpaid principal amount of all Equipment Notes on the date notice of the
Company's election to redeem is given to the Trustee pursuant to Section
9.11(a), by a fraction, the numerator of which shall be the Fair Value of the
Equipment with respect to which such Event of Loss occurred and the denominator
of which shall be the aggregate Fair Value of all Equipment subject to the Lien
hereof immediately prior to the occurrence of such Event of Loss. The redemption
price payable upon a redemption pursuant to this Section 2.12(b) shall equal the
principal amount of the Equipment Notes to be redeemed as determined pursuant to
the immediately preceding sentence, together with accrued and unpaid interest on
such principal amount to the date of such redemption but without the payment of
any premium.


                  (c) The Trustee shall give prompt notice to the Noteholders of
any redemption pursuant to this Section 2.12.


                  (d) The Equipment Notes are not subject to redemption or
prepayment except as provided in this Section 2.12 and in Section 3.03 of this
Indenture.


                                  ARTICLE III


                      RECEIPT, DISTRIBUTION AND APPLICATION
                       OF INCOME FROM THE INDENTURE ESTATE


                  Section 3.01 Payments Prior to Indenture Event of Default.
Except as otherwise provided in Section 3.03, any money paid over by the Company
to the Trustee for payment on the Equipment Notes shall be distributed by the
Trustee as promptly as possible to the holders of the Equipment Notes to pay in
full the aggregate amount of the payment or payments of principal, premium, if
any, and interest (as well as any interest on overdue principal) then due, such
distribution to be made ratably, in the proportion that the amount of such
payment or payments then due or so scheduled with respect to each such Equipment
Note bears to the aggregate amount of payments then due under all such Equipment
Notes. The amount so distributed to a Holder of an Equipment Note shall be
applied by such Holder in payment of such Equipment Note in accordance with the
terms of Section 2.09.


                  Section 3.02 [Reserved].


                  Section 3.03 Payments After Indenture Event of Default. (a)
All payments received and amounts realized by the Trustee after an Indenture
Event of Default shall have occurred and be continuing and after the Equipment
Notes shall have been accelerated pursuant to Section 4.02 or the Trustee has
elected to foreclose or otherwise enforce its rights under this Indenture
(including any amounts realized by the Trustee from the exercise of any remedies
pursuant to Article IV), as well as all payments or amounts then held or
thereafter received by the Trustee as part of the Indenture Estate while such
Indenture Event of Default shall be continuing, shall be distributed forthwith
by the Trustee in the following order of priority: first, so much of such
payments or amounts as shall be required to pay or reimburse the Trustee for any
unpaid fees for its services under this Indenture and any tax, liability,
expense (including reasonable attorneys' fees) or other loss incurred by the
Trustee (to the extent reimbursable and not previously reimbursed and to the
extent reasonably incurred in connection with its duties as 






                                       9











Trustee) shall be distributed to the Trustee; second, so much of such payments
or amounts as shall be required to reimburse the Holders of the Equipment Notes
for payments made by them to the Trustee pursuant to Article V (to the extent
not previously reimbursed), shall be distributed to such Holders of the
Equipment Notes, without priority of one over the other, in accordance with the
amount of the payment or payments made by, or payable to, each such Holder;
third, so much of such payments or amounts as shall be required to pay in full
the aggregate unpaid principal amount of all Equipment Notes, plus the accrued
but unpaid interest thereon to the date of distribution, shall be distributed to
the Holders of the Equipment Notes, and in case the aggregate amount so to be
distributed shall be insufficient to pay in full the aforesaid amounts, then,
ratably, without priority of one over another, in the proportion that the
aggregate unpaid principal amount of all Equipment Notes held by each such
Holder, plus the accrued but unpaid interest thereon to the date of
distribution, bears to the aggregate unpaid principal amount of all Equipment
Notes, plus the accrued but unpaid interest thereon to the date of distribution;
and fourth, the balance, if any, of such payments or amounts remaining
thereafter shall be distributed to, or as directed by, the Company;


                  (b) If an Indenture Event of Default shall have occurred and
be continuing, the Trustee shall not make any distribution to the Company but
shall hold amounts otherwise distributable to the Company as collateral security
for the obligations secured hereby until such time as no Indenture Event of
Default shall be continuing hereunder or such amounts are applied pursuant to
Section 3.03(a).


                  Section 3.04 Other Payments. Except as otherwise provided in
Section 3.03,


                  (a) any payments received by the Trustee for which no
         provision as to the application thereof is made elsewhere in this
         Article III, and


                  (b) all payments received and amounts realized by the Trustee
         with respect to the Items of Equipment to the extent received or
         realized at any time after payment in full of the principal of and
         interest and premium, if any, on all Equipment Notes, as well as any
         other amounts remaining as part of the Indenture Estate after payment
         in full of the principal of and interest and premium, if any, on all
         Equipment Notes issued hereunder,


shall be distributed forthwith by the Trustee in the order of priority set forth
in Section 3.03, except that in the case of any payment described in clause (b)
above, such payment shall be distributed omitting clause "third" of such Section
3.03(a).


                                   ARTICLE IV


                             REMEDIES OF THE TRUSTEE
                       UPON AN INDENTURE EVENT OF DEFAULT


                  Section 4.01 Indenture Events of Default. The following events
shall constitute "Indenture Events of Default" and each such Indenture Event of
Default shall be deemed to exist and continue so long as, but only so long as,
it shall not have been remedied:






                                       10











(a) default by the Company in making any payment when due of
         any principal of or premium (if any) on, any Equipment Note;


                  (b) default by the Company in making any payment when due of
         any interest on any Equipment Note, and the continuance of such default
         unremedied for 10 Business Days after the same shall have become due
         and payable;


                  (c) any failure by the Company or the Guarantor to observe or
         perform in any material respect any covenant or obligation of it, in
         this Indenture or the Equipment Notes if, but only if, such failure is
         not remedied within a period of 120 days after there has been given to
         the Company or the Guarantor, as the case may be, by the Trustee or the
         Holders of 25% or more in aggregate principal amount of the Equipment
         Notes then outstanding a written notice specifying such failure and
         requiring it to be remedied;


                  (d) any representation or warranty made by the Company
         hereunder, or by any representative of the Company in any document or
         certificate furnished to the Trustee in connection herewith or pursuant
         hereto, shall prove at any time to have been incorrect in any material
         adverse respect as of the date made and such incorrectness shall remain
         material and unremedied for a period of 120 days after the date on
         which there has been given to the Company by the Trustee or the Holders
         of 25% or more in aggregate principal amount of the Equipment Notes
         then outstanding a written notice specifying such incorrectness;


                  (e) the Guarantee shall cease to be in full force and effect
         or the Guarantor shall take any action to seek to have the Guarantee
         declared void or unenforceable;


                  (f) either the Company or the Guarantor shall (i) commence a
         voluntary case or other proceeding seeking liquidation, reorganization
         or other relief with respect to itself or its debts under any
         bankruptcy, insolvency or other similar law now or hereafter in effect,
         or seeking the appointment of a trustee, receiver, liquidator,
         custodian or other similar official of it or any substantial part of
         its property, or (ii) consent to any such relief or to the appointment
         of or taking possession by any such official in any voluntary case or
         other proceeding commenced against it, or (iii) admit in writing its
         inability to pay its debts generally as they come due, or (iv) make a
         general assignment for the benefit of creditors, or (v) take any
         corporate action to authorize any of the foregoing; or


                  (g) an involuntary case or other proceeding shall be commenced
         against either the Company or the Guarantor seeking liquidation,
         reorganization or other relief with respect to it or its respective
         debts under any bankruptcy, insolvency or other similar law now or
         hereafter in effect, or seeking the appointment of a trustee, receiver,
         liquidator, custodian or other similar official of it or any
         substantial part of its property, and such involuntary case or other
         proceeding shall remain undismissed and unstayed for a period of 90
         days.


                  Section 4.02 Acceleration; Rescission and Annulment. If an
Indenture Event of Default (other than as described in Section 4.01(f) or (g))
shall occur and be continuing, the Trustee may, and when instructed by the
Holders of at least 25% in aggregate principal amount 






                                       11











of the Equipment Notes then outstanding, shall, by written notice to the
Company, declare the unpaid principal amount of all Equipment Notes then
outstanding to be immediately due and payable, together with all accrued and
unpaid interest thereon and all other amounts due thereunder. If an Indenture
Event of Default described in Section 4.01(f) or (g) shall have occurred and be
continuing, the unpaid principal amount of all Equipment Notes then outstanding,
together with all accrued and unpaid interest thereon and all other amounts due
thereunder, shall immediately become due and payable, without any notice or
action by the Trustee or any Noteholder, to the fullest extent permitted by law.
At any time after acceleration and prior to the sale of any of the Indenture
Estate pursuant to this Article IV, a Majority in Interest, by written notice to
the Company and the Trustee, may rescind and annul such acceleration and thereby
annul its consequences if: (i) there has been paid to or deposited with the
Trustee an amount sufficient to pay all overdue installments of interest on the
Equipment Notes, and the principal of and premium, if any, on any Equipment
Notes that have become due otherwise than by such acceleration, (ii) the
rescission would not conflict with any judgment or decree, and (iii) all other
Indenture Defaults and Indenture Events of Default, other than nonpayment of
principal or interest on the Equipment Notes that have become due solely because
of such acceleration, have been cured or waived.


                  Section 4.03 Remedies with Respect to Indenture Estate. (a) If
an Indenture Event of Default shall have occurred and be continuing, and the
Equipment Notes shall have been accelerated (and such acceleration shall not
have been rescinded) pursuant to Section 4.02, then and in every such case the
Trustee shall be entitled to exercise any or all of the rights and powers and
pursue any and all of the remedies pursuant to this Article IV and may recover
judgment in its own name as Trustee against the Company and Indenture Estate and
may take possession of all or any part of the Indenture Estate, and may exclude
the Company and all persons claiming under the Company wholly or partly
therefrom.


                  (b) The Trustee may, if at the time such action may be lawful
and always subject to compliance with any mandatory legal requirements, either
with or without taking possession, and either before or after taking possession,
and without instituting any legal proceedings whatsoever, and having first given
written notice of such sale to the Company at least 30 days prior to the date of
such sale or the date on which the Trustee enters into a binding contract for a
private sale, and any other notice which may be required by law, sell and
dispose of the Indenture Estate, or any part thereof, or interest therein, at
public auction to the highest bidder or at private sale in one lot as an
entirety or in separate lots, and either for cash or on credit and on such terms
as the Trustee may determine, and at any place (whether or not it be the
location of the Indenture Estate or any part thereof) and time designated in the
notice above referred to. Any such public sale or sales may be adjourned from
time to time by announcement at the time and place appointed for such sale or
sales, or for any such adjourned sale or sales, without further notice, and the
Trustee or the Holder or Holders of any Equipment Notes, or any interest
therein, may bid and become the purchaser at any such public sale. The Trustee
may exercise such right without possession or production of the Equipment Notes
or proof of ownership thereof, and as representative of the Holders may exercise
such right without including the Holders as parties to any suit or proceeding
relating to foreclosure of any property in the Indenture Estate. The Company
hereby irrevocably constitutes the Trustee the true and lawful attorney-in-fact
of the Company (in the name of the Company or otherwise) for the purpose of
effecting any sale, assignment, transfer or delivery for enforcement of the Lien
of this






                                       12











Indenture, whether pursuant to foreclosure or power of sale or otherwise, to
execute and deliver all such bills of sale, assignments and other instruments as
the Trustee may consider necessary or appropriate, with full power of
substitution, the Company hereby ratifying and confirming all that such attorney
or any substitute shall lawfully do by virtue hereof. Nevertheless, if so
requested by the Trustee or any purchaser, the Company shall ratify and confirm
any such sale, assignment, transfer or delivery, by executing and delivering to
the Trustee or such purchaser all bills of sale, assignments, releases and other
proper instruments to effect such ratification and confirmation as may be
designated in any such request.


                  (c) The Company agrees, to the fullest extent that it lawfully
may, that, in case one or more of the Indenture Events of Default shall have
occurred and be continuing, then, in every such case, the Trustee may take
possession of all or any part of the Indenture Estate and, subject to the rights
of the lessees under the Leases, may exclude the Company and all persons
claiming under any of them wholly or partly therefrom. At the request of the
Trustee, the Company shall promptly execute and deliver to the Trustee such
instruments of title and other documents as the Trustee may deem necessary or
advisable to enable the Trustee or an agent or representative designated by the
Trustee, at such time or times and place or places as the Trustee may specify,
to obtain possession, subject to the rights of the lessees under the Leases, of
all or any part of the Indenture Estate. If the Company shall fail for any
reason to execute and deliver such instruments and documents to the Trustee, the
Trustee may pursue all or part of the Indenture Estate wherever it may be found
and may enter any of the premises of the Company wherever the Indenture Estate
may be or be supposed to be and search for the Indenture Estate and take
possession of and remove the Indenture Estate, subject to the rights of the
lessees under the Leases. Upon every such taking of possession, the Trustee may,
from time to time, at the expense of the Indenture Estate, make all such
expenditures for maintenance, insurance, repairs, replacements, alterations,
additions and improvements to any of the Indenture Estate, as it may deem proper
or as it may otherwise be directed to do so by a Majority in Interest. In each
such case, and subject to the rights of the lessees under the Leases, the
Trustee shall have the right to use, operate, store, control or manage the
Indenture Estate, and to carry on the business and to exercise all rights and
powers of the Company relating to the Indenture Estate, including the right to
enter into any and all such agreements with respect to the maintenance,
operation, leasing or storage of the Indenture Estate or any part thereof; and
the Trustee shall be entitled to collect and receive all tolls, rents, revenues,
issues, income, products and profits of the Indenture Estate and every part
thereof, without prejudice, however, to the right of the Trustee under any
provision of this Indenture to collect and receive all cash held by, or required
to be deposited with, the Trustee hereunder. Such tolls, rents, revenues,
issues, income, products and profits shall be applied to pay the expenses of
holding and operating the Indenture Estate and of conducting the business
thereof, and of all maintenance, repairs, replacements, alterations, additions
and improvements, and to make all payments which the Trustee may be required or
may elect to make, if any, for taxes, assessments, insurance or other proper
charges upon the Indenture Estate or any part thereof (including the employment
of engineers and accountants to examine, inspect and make reports upon the
properties and books and records of the Company), and all other payments which
the Trustee may be required or authorized to make under any provision of this
Indenture, as well as just and reasonable compensation for the services of the
Trustee, and of all persons properly engaged and employed by the Trustee,
including the reasonable expenses of the Trustee. Any action by the Trustee
pursuant to this Section 4.03(c) 






                                       13











will in all respects be subject to compliance with any mandatory legal
requirements applicable to any such action and to the rights of the lessees
under the Leases, if any.


                  (d) If an Indenture Event of Default occurs and is continuing
and the Trustee shall have obtained possession of an Item of Equipment, the
Trustee shall not be obligated to cause any Person to use or operate such Item
of Equipment or cause such Item of Equipment to be used or operated directly or
indirectly by itself or through agents or other representatives or to lease,
license or otherwise permit or provide for the use or operation of such Item of
Equipment by any other Person unless (i) the Trustee, as directed by a Majority
in Interest, shall have been able to obtain insurance in kinds, at rates and in
amounts satisfactory to a Majority in Interest to protect the Indenture Estate
and the Trustee, as trustee and individually, against any and all liability for
loss or damage to such Item of Equipment and for public liability and property
damage resulting from use or operation of such Item of Equipment and (ii) funds
are available in the Indenture Estate to pay for all such insurance or, in lieu
of such insurance, the Trustee is furnished with indemnification from the
holders of the Equipment Notes or any other Person upon terms and in amounts
satisfactory to the Trustee in its discretion to protect the Indenture Estate
and the Trustee, as trustee and individually, against any and all such
liabilities.


                  (e) If an Indenture Event of Default shall occur and be
continuing, the Trustee may proceed to protect and enforce this Indenture and
the Equipment Notes by suits or proceedings in equity, at law or in bankruptcy,
and whether for specific performance of any covenant or agreement or in
execution or aid of any power herein granted, or for foreclosure hereunder, or
the appointment of a receiver or receivers for the Indenture Estate or any part
thereof, or for the recovery of a judgment for the indebtedness secured hereby,
or the enforcement of any other legal or equitable remedy available to a
mortgagee or a secured party under the Uniform Commercial Code of the relevant
jurisdiction or any other applicable law.


                  (f) If an Indenture Event of Default shall occur and be
continuing, the Trustee and the Company shall give the "account debtor" (as
defined in Article 9 of the Uniform Commercial Code of the relevant
jurisdiction) under each Lease a notice in substantially the form of Exhibit C
hereto. The Company hereby irrevocably constitutes the Trustee the true and
lawful attorney-in-fact of the Company (in the name of the Company or otherwise)
for the purpose of giving such notice.


                  Section 4.04 Waiver of Existing Defaults. A Majority in
Interest by notice to the Trustee on behalf of all Holders of the Equipment
Notes may waive any past default hereunder and its consequences, except that the
consent of each Holder of an Equipment Note affected thereby shall be required
to waive a default (i) in the payment of the principal of, premium, if any, or
interest on any Equipment Note or (ii) in respect of a covenant or provision
hereof which under Article VIII hereof cannot be modified or amended without the
consent of the Holder of each Equipment Note affected. Upon any such waiver,
such default shall cease to exist, and any Indenture Event of Default arising
therefrom shall be deemed to have been cured for every purpose of this
Indenture; but no such waiver shall extend to any subsequent or other default or
impair any right consequent thereon.


                  Section 4.05 Control by Majority. A Majority in Interest may
direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee or 






                                       14











exercising any trust or power conferred on the Trustee. However, the Trustee may
refuse to follow any direction that conflicts with law or this Indenture that
may involve the Trustee in personal liability, or that the Trustee determines in
good faith may be unduly prejudicial to the rights of Holders of the Equipment
Notes not joining in the giving of such direction, and may take any other action
it deems proper that is not inconsistent with any such direction received from
Holders of the Equipment Notes.


                  Section 4.06 Limitation on Suits. A Holder may not pursue any
remedy with respect to this Indenture or the Equipment Notes unless:


                  (i) the Holder gives the Trustee written notice of a
         continuing Indenture Event of Default;


                  (ii) the Holders of at least 25% in aggregate principal amount
         of outstanding Equipment Notes make a written request to the Trustee to
         pursue the remedy;


                  (iii) such Holder or Holders offer the Trustee indemnity
         satisfactory to the Trustee against any costs, liability or expense;


                  (iv) the Trustee does not comply with the request within 60
         days after receipt of the request and the offer of indemnity; and


                  (v) during such 60-day period, a Majority in Interest does not
         give the Trustee a direction that is inconsistent with the request.


                  A Holder may not use this Indenture to prejudice the rights of
another Holder or to obtain a preference or priority over such other Holder.


                  Section 4.07 Rights of Holders to Receive Payment.
Notwithstanding any other provision of this Indenture, the right of any Holder
of an Equipment Note to receive payment of principal of, premium, if any, or
interest on such Holder's Equipment Note on or after the respective due dates
expressed on such Equipment Note, or to bring suit for the enforcement of any
such payment on or after such respective dates, shall not be impaired or
affected without the consent of such Holder.


                  Section 4.08 Delay or Omission Not Waiver. No delay or
omission of the Trustee or of any Holder to exercise any right or remedy
accruing upon any Indenture Event of Default shall impair any such right or
remedy or constitute a waiver of any such Indenture Event of Default or an
acquiescence therein. Every right and remedy given under this Indenture or by
law to the Trustee or to the Holders may be exercised from time to time, and as
often as may be deemed expedient, by the Trustee or by the Holders, as the case
may be.


                  Section 4.09 Remedies Cumulative. Each and every right, power
and remedy herein specifically given to the Trustee or otherwise in this
Indenture shall be cumulative and shall be in addition to every other right,
power and remedy herein specifically given or now or hereafter existing at law,
in equity or by statute, and each and every right, power and remedy whether
specifically herein given or otherwise existing may be exercised from time to
time and as often and in such order as may be deemed expedient by the Trustee,
and the exercise or the 






                                       15











beginning of the exercise of any power or remedy shall not be construed to be a
waiver of the right to exercise at the time or thereafter any other right, power
or remedy. No delay or omission by the Trustee in the exercise of any right,
remedy or power or in the pursuance of any remedy shall impair any such right,
power or remedy or be construed to be a waiver of any default on the part of the
Company or to be an acquiescence therein.


                  Section 4.10 Discontinuance of Proceedings. In case the
Trustee shall have proceeded to enforce any right, power or remedy under this
Indenture by foreclosure, entry or otherwise, and such proceedings shall have
been discontinued or abandoned for any reason or shall have been determined
adversely to the Trustee, then and in every such case the Company and, the
Trustee shall be restored to their former positions and rights hereunder with
respect to the Indenture Estate, and all rights, remedies and powers of the
Trustee shall continue as if no such proceedings had been undertaken (but
otherwise without prejudice).


                  Section 4.11 Undertaking for Costs. In any suit for the
enforcement of any right or remedy under this Indenture or in any suit against
the Trustee for any action taken or omitted by it as a Trustee, a court in its
discretion may require the filing by any party litigant in the suit of an
undertaking to pay the costs of the suit, and the court in its discretion may
assess reasonable costs, including reasonable attorney's fees and expenses,
against any party litigant in the suit, having due regard to the merits and good
faith of the claims or defenses made by the party litigant, provided that the
provisions of this Section shall not apply to any suit instituted by any Holder
of an Equipment Note.


                                   ARTICLE V


                                   THE TRUSTEE


                  Section 5.01 Acceptance of Trusts and Duties. The Trustee
accepts the trusts hereby created and applicable to it and agrees to perform the
same but only upon the terms of this Indenture and agrees to receive and
disburse all money received by it constituting part of the Indenture Estate in
accordance with the terms hereof.


                  Section 5.02 Certain Duties and Responsibilities. (a) Except
during the continuance of an Indenture Event of Default:


                  (i) the Trustee undertakes to perform such duties as are
         specifically set forth in this Indenture, and no implied covenants or
         obligations shall be read into this Indenture against the Trustee; and


                  (ii) in the absence of bad faith on its part, the Trustee may
         conclusively rely, as to the truth of the statements and the
         correctness of the opinions expressed therein, upon certificates or
         opinions furnished to the Trustee and conforming to the requirements of
         this Indenture; but in the case of any such certificates or opinions
         which by any provision hereof are specifically required to be furnished
         to the Trustee, the Trustee shall be under a duty to examine the same
         to determine whether or not they conform to the requirements of this
         Indenture (but need not confirm or investigate the accuracy of
         mathematical calculations or other facts stated therein).






                                       16











(b) In case an Indenture Event of Default shall occur and be
continuing, the Trustee shall exercise such of the rights and powers vested in
it by this Indenture, and use the same degree of care and skill in their
exercise, as a prudent person would exercise or use under the circumstances in
the conduct of his own affairs.


                  (c) No provision of this Indenture shall be construed to
relieve the Trustee from liability for its own grossly negligent action (or
negligent action in the handling of funds), its own grossly negligent failure to
act (or negligent failure to action in the handling of funds), or its own
willful misconduct, except that:


                  (i) this subsection shall not be construed to limit the effect
         of subsection (a) of this Section;


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


                  (iii) the Trustee shall not be liable with respect to any
         action taken or omitted to be taken by it in good faith in accordance
         with the direction of a Majority in Interest relating to the time,
         method and place of conducting any proceeding for any remedy available
         to the Trustee, or exercising any trust or power conferred upon the
         Trustee, under this Indenture; and


                  (iv) no provision of this Indenture shall require the Trustee
         to expend or risk its own funds in the performance of any of its duties
         hereunder, or in the exercise of any of its rights or powers, if it
         shall have reasonable grounds for believing that repayment of such
         funds or adequate indemnity against such risk is not reasonably assured
         to it.


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


                  Section 5.03 Notice of Indenture Defaults. If the Trustee
shall have knowledge of any Indenture Default or Indenture Event of Default
hereunder, the Trustee shall promptly give notice thereof to the Company in
accordance with Section 11.10 and to all Holders, as their names and addresses
appear in the Equipment Note Register, unless such Indenture Default shall have
been cured or waived; provided, however, that, except in the case of a default
in the payment of the principal of (or premium, if any) or interest on any
Equipment Note, the Trustee shall be protected in withholding such notice if and
so long as the board of directors, the executive committee or a trust committee
of directors and/or Responsible Officers of the Trustee in good faith determine
that the withholding of such notice is in the interest of the Holders.


                  Section 5.04 Certain Rights of Trustee. Except as otherwise
provided in Section 5.02:


                  (a) the Trustee may conclusively rely and shall be protected

         certificate, statement, instrument, opinion, report, notice, request,
         direction, consent, order, bond, debenture or other paper 






                                       17











or document believed by it to be genuine and to have been signed or
         presented by the proper party or parties;


                  (b) whenever in the administration of this Indenture the
         Trustee shall deem it desirable that a matter be proved or established
         prior to taking, suffering or omitting any action hereunder, the
         Trustee (unless other evidence be herein specifically prescribed) may,
         in the absence of bad faith on its part, conclusively rely upon an
         Officer's Certificate of the Company;


                  (c) the Trustee may consult with counsel of its choice and the
         advice of such counsel or any Opinion of Counsel shall be full and
         complete authorization and protection in respect of any action taken,
         suffered or omitted by it hereunder in good faith and in reliance
         thereon;


                  (d) the Trustee shall be under no obligation to exercise any
         of the rights or powers vested in it by this Indenture at the request
         or direction of any of the Holders pursuant to this Indenture, unless
         such Holders shall have offered to the Trustee security or indemnity
         satisfactory to it against the cost, expenses and liabilities which
         might be incurred by it in compliance with such request or direction;


                  (e) the 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, direction,
         consent, order, bond, debenture or other paper or document;


                  (f) the Trustee may execute any of the trusts or powers
         hereunder or perform any duties hereunder either directly or by or

                  (g) the Trustee shall not be deemed to have notice of any
         Indenture Default or Indenture Event of Default unless a Responsible
         Officer of the Trustee has actual knowledge thereof or unless written
         notice of any such event is received by the Trustee at the Corporate
         Trust Office of the Trustee, and such notice references the Equipment
         Notes and this Indenture; and


                  (h) the Trustee may request that the Company deliver an
         Officer's Certificate setting forth the names of individuals and/or
         titles of officers authorized at such time to take specified actions
         pursuant to this Indenture, which Officer's Certificate may be signed
         by any person authorized to sign an Officer's Certificate, including
         any person specified as so authorized in any such certificate

Equipment Notes. The recitals contained herein and in the Equipment Notes,

delivered to the Trustee for execution an Indenture Supplement or a Memorandum
of Trust, as contemplated by Section 9.11, 9.13 or 9.14, the Trustee agrees,

                  Section 5.08 Effect of Replacements. In the event of the
substitution of a Replacement Item of Equipment, all provisions of this

Equipment being replaced.

Company, shall exclude and withhold from each payment of principal, premium, if
any, and interest and other amounts due hereunder or under the Equipment Notes
any and all withholding taxes applicable thereto as required by law. The Trustee
agrees to act as such withholding agent and, in connection therewith, whenever
any present or future taxes or similar charges are required to be withheld by it
with respect to any amounts payable in respect of the Equipment Notes, to
withhold such amounts and timely pay the same to the appropriate authority in
the name of and on behalf of the holders of the Equipment Notes, that it will
file any necessary withholding tax returns or statements when due, and that, as
promptly as possible after the payment thereof, it will deliver to each holder
of an Equipment Note appropriate documentation showing the payment thereof,
together with such additional documentary evidence as such holders may
reasonably request from time to time.

WITH RESPECT TO THE ITEMS OF EQUIPMENT WHATSOEVER, or (ii) any representation or
warranty as to the validity, legality or enforceability of this Indenture, the
Equipment Notes, or any Indenture Supplement or any other document or instrument
or as to the correctness of any statement contained in any thereof (except as to
the representations and warranties made by the Trustee herein).


                  Section 5.11 No Segregation of Moneys; No Interest;
Investments. (a) Subject to Section 5.12(b), no money received by the Trustee
hereunder need be segregated in any manner except to the extent required by law,
and any such money may be deposited under such general conditions for the
holding of trust funds as may be prescribed by law applicable to the Trustee,
and, except as otherwise agreed by the Trustee, the Trustee shall not be liable
for any interest thereon.






                                       19











(b) Any amounts held by the Trustee pursuant to the express
terms of this Indenture and not required to be distributed as herein provided
shall be invested and reinvested by the Trustee from time to time in Specified
Investments at the written direction and at the risk and expense of the Company,
except that in the absence of any such direction or after an Indenture Event of
Default shall have occurred and be continuing, such amounts shall be so invested
by the Trustee in Specified Investments of the type specified in clause (f) of
the definition thereof, except as provided below, and the Trustee shall hold any
such Specified Investments until maturity. Any net income or gain realized as a
result of any such investments shall be held as part of the Indenture Estate and
shall be applied by the Trustee at the same times, on the same conditions and in
the same manner as the amounts in respect of which such income or gain was
realized are required to be distributed in accordance with the provisions hereof
pursuant to which such amounts were required to be held and if no Indenture
Event of Default shall have occurred and be continuing any excess shall be paid
to the Company upon its request. Any such Specified Investments may be sold or
otherwise reduced to cash (without regard to maturity date) by the Trustee
whenever necessary to make any application as required by such provision. The
Trustee shall have no liability for any loss resulting from any such investment
other than by reason of the willful misconduct or negligence of the Trustee.


                  Section 5.12 No Compensation from Holders or Indenture Estate.
The Trustee agrees that it shall have no right against the Holders of the
Equipment Notes or, except as provided in Sections 3.03 and 4.03, the Indenture
Estate, for any fee as compensation for its services hereunder.

Trustee shall have no duty as to any Indenture Estate in its possession or
control or in the possession or control of any agent or bailee or any income
thereon or as to preservation of rights against prior parties or any other
rights pertaining thereto and the Trustee shall not be responsible for filing
any financing or continuation statements or recording any documents or
instruments in any public office at any time or times or otherwise perfecting or
maintaining the perfection of any security interest in the Indenture Estate.

existence, genuineness or value of any of the Indenture Estate or for the
validity, perfection, priority or enforceability of the Liens in any of the
Indenture Estate, whether impaired by operation of law or by reason of any
action or omission to act on its part hereunder, except to the extent such
action or omission constitutes negligence, bad faith or willful misconduct on
the part of the Trustee, (ii) for the validity or sufficiency of the Indenture
Estate or any agreement or assignment contained therein, (iii) for the validity
of the title of the Company to the Indenture Estate, (iv) for insuring the
Indenture Estate or (v) for the payment of taxes, charges, assessments or Liens
upon the Indenture Estate or otherwise as to the maintenance of the Indenture
Estate.

Indenture to the contrary notwithstanding, in no event shall the Trustee be
liable under or in connection with this Indenture for indirect, special,
incidental, punitive or consequential losses or damages of any kind whatsoever,
including but not limited to lost profits, whether or not foreseeable, even if
the 






                                       20











Trustee has been advised of the possibility thereof and regardless of the form
of action in which such damages are sought.

                  Section 6.01 Scope of Indemnification. The Company hereby
agrees, whether or not any of the transactions contemplated hereby shall be
consummated, to assume liability for, and does hereby indemnify, protect, save
and keep harmless the Trustee, in each of its capacities hereunder, including in
its individual capacity, and its successors, assigns, agents and servants, from
and against any and all liabilities (including strict tort liability),

other charges on, based on, or measured by, any fees or compensation received by
the Trustee for services rendered in connection with the transactions
contemplated hereby), claims, actions, suits, costs, expenses or disbursements
(including reasonable legal fees and expenses) of any kind and nature whatsoever
which may be imposed on, incurred by or asserted against the Indenture Estate or
the Trustee (whether or not also indemnified against by any other person under
any other document) in any way relating to or arising out of this Indenture, any
Indenture Supplement or the Equipment Notes, or the enforcement of any of the
terms of any thereof, or in any way relating to or arising out of the

delivery, lease, sublease, registration, re-registration, possession, use,
operation, condition, sale, return or other disposition of the Items of
Equipment or any part thereof (including, without limitation, latent and other
defects, whether or not discoverable, and any claim for patent, trademark or
copyright infringement), or in any way relating to or arising out of the
administration of the Indenture Estate or the action or inaction of the Company
hereunder, or the Trustee hereunder except only in the case of willful
misconduct, bad faith or gross negligence (or negligence in the handling of
funds) of the Trustee in the performance of its duties hereunder or the breach
of any of its representations and warranties set forth herein.


                  Section 6.02 Compensation. The Company agrees


                  (a) to pay to the Trustee from time to time such compensation
as the Company and the Trustee shall from time to time agree in writing for all
services rendered by it hereunder (which compensation shall not be limited by
any provision of law in regard to the compensation of a trustee of an express
trust); and


                  (b) except as otherwise expressly provided herein, to
reimburse the Trustee upon its request for all reasonable expenses,
disbursements and advances incurred or made by the Trustee in accordance with
any provision of this Indenture (including the reasonable compensation and the
expenses and disbursements of its agents and counsel), except any such expense,
disbursement or advance as may be attributable to its negligence, wilfull
misconduct or bad faith.


                  The Trustee shall have a lien prior to the Equipment Notes as
to all property and funds held by it hereunder for any amount owing it or any
predecessor Trustee pursuant to 






                                       21











Sections 6.01 and 6.02, except with respect to funds held in trust for the
benefit of the Holders of particular Equipment Notes.


                  When the Trustee incurs expenses or renders services in
connection with an Indenture Event of Default specified in Section 4.01(f) or
Section 4.01(g), the expenses (including the reasonable charges and expenses of
its counsel) and the compensation for the services are intended to constitute
expenses of administration under any applicable federal or state bankruptcy,
insolvency or other similar law.


                  The provisions of this Section 6.02 shall survive the
termination of this Indenture.


                                  ARTICLE VII


                               SUCCESSOR TRUSTEES


                  Section 7.01 Resignation of Trustee; Appointment of Successor.
(a) The resignation or removal of the Trustee and the appointment of a successor
Trustee shall become effective only upon the successor Trustee's acceptance of
appointment as provided in this Section 7.01. The Trustee or any successor
thereto may resign at any time without cause by giving at least 30 days' prior
written notice to the Company and the Holders of the Equipment Notes. A Majority
in Interest may at any time remove the Trustee without cause upon 60 days prior
written notice by an instrument in writing delivered to the Company and the
Trustee. In addition, the Company may remove the Trustee if: (i) the Trustee
fails to comply with Section 7.01(c), (ii) the Trustee is adjudged a bankrupt or
an insolvent, (iii) a receiver or public officer takes charge of the Trustee or
its property or (iv) the Trustee becomes incapable of acting as provided herein.


                  In the case of the resignation or removal of the Trustee, the
Company shall promptly appoint a successor Trustee, provided that a Majority in
Interest may appoint, within one year after such resignation or removal, a
successor Trustee which may be other than the successor Trustee appointed as
provided above, and such successor Trustee appointed as provided above shall be
superseded by the successor Trustee so appointed by a Majority in Interest. If a
successor Trustee shall not have been appointed and accepted its appointment
hereunder within 60 days after the Trustee gives notice of resignation as
provided above, the retiring Trustee, the Company or a Majority in Interest may
petition any court of competent jurisdiction for the appointment of a successor
Trustee. Any successor Trustee so appointed by such court shall immediately and
without further act be superseded by any successor Trustee appointed as provided
in the proviso to the fifth sentence of this paragraph (a) within one year from
the date of the appointment by such court.


                  (b) Any successor Trustee, however appointed, shall execute
and deliver to the Company and to the predecessor Trustee an instrument
accepting such appointment, and thereupon such successor Trustee, without
further act, shall become vested with all the estates, properties, rights,
powers, duties and trusts of the predecessor Trustee hereunder in the trusts
hereunder applicable to it with like effect as if originally named the Trustee
herein; but nevertheless, upon the written request of such successor Trustee,
such predecessor Trustee shall 






                                       22











execute and deliver an instrument transferring to such Trustee, upon the trusts
herein expressed applicable to it, all the estates, properties, rights, powers
and trusts of such predecessor Trustee, and such Trustee shall duly assign,
transfer, deliver and pay over to such successor Trustee all money or other
property then held by such predecessor Trustee hereunder.


                  (c) The Trustee shall be a bank or trust company, organized
under the laws of the United States of America or any state thereof, having a
combined capital and surplus of at least $50,000,000 (or the obligations and
liabilities of which are irrevocably and unconditionally guaranteed by an
affiliated company having a combined capital and surplus of at least
$50,000,000), if there be such an institution willing, able and legally
qualified to perform the duties of the Trustee hereunder upon reasonable or
customary terms.


                  (d) Any corporation into which the Trustee may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which the Trustee shall be a
party, or any corporation to which substantially all the corporate trust
business of the Trustee may be transferred, shall, subject to the terms of
paragraph (c) of this Section, be the Trustee under this Indenture without
further act.


                  Section 7.02 Appointment of Co-Trustee. It is the purpose of
this Indenture that there shall be no violation of any law of any jurisdiction
denying or restricting the right of banking corporations or associations to
transact business as trustee in such jurisdiction. It is recognized that in case
of litigation under this Indenture, and in particular in case of the enforcement
thereof on default, or in the case the Trustee deems that by reason of any
present or future law of any jurisdiction it may not exercise any of the powers,
rights or remedies herein granted to the Trustee or hold title to the
properties, in trust, as herein granted or take any action which may be
desirable or necessary in connection therewith, it may be necessary that the
Trustee appoint an individual or institution as a separate or co-trustee,
provided that unless an Indenture Event of Default shall have occurred and be
continuing, any such appointment of a co-trustee shall be subject to the consent
of the Company, which consent shall not be unreasonably withheld. The following
provisions of this Section are adopted to these ends.


                  In the event that the Trustee appoints an additional
individual or institution as a separate or co-trustee, each and every remedy,
power, right, claim, demand, cause of action, immunity, estate, title, interest
and lien expressed or intended by this Indenture to be exercised by or vested in
or conveyed to the Trustee with respect thereto shall be exercisable by and vest
in such separate or co-trustee but only to the extent necessary to enable such
separate or co-trustee to exercise such powers, rights and remedies, and only to
the extent that the Trustee by the laws of any jurisdiction is incapable of
exercising such powers, rights and remedies and every covenant and obligation
necessary to the exercise thereof by such separate or co-trustee shall run to
and be enforceable by either of them.


                  Should any instrument in writing from the Company be required
by the separate or co-trustee so appointed by the Trustee for more fully and
certainly vesting in and confirming to him or it such properties, rights,
powers, trusts, duties and obligations, any and all such instruments in writing
shall, on request, be executed, acknowledged and delivered by the Company;
provided, that if an Indenture Event of Default shall have occurred and be
continuing, if the Company does not execute any such instrument within fifteen
(15) days after request 






                                       23











therfor, the Trustees shall be empowered as an attorney-in-fact for the Company
to execute any such instrument in the Company's name and stead. In case any
separate or co-trustee or a successor to either shall die, become incapable of
acting, resign or be removed, all the estates, properties, rights, powers,
trusts, duties and obligations of such separate or co-trustee, so far as
permitted by law, shall vest in and be exercised by the Trustee until the
appointment of a new trustee or successor to such separate or co-trustee.


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


                  (i) all rights and powers, conferred or imposed upon the
         Trustee shall be conferred or imposed upon and may be exercised or
         performed by such separate trustee or co-trustee; and


                  (ii) no trustee hereunder shall be personally liable by reason
         of any act or omission of any other trustee hereunder.


                  Any notice, request or other writing given to the Trustee
shall be deemed to have been given to each of the then separate trustees and
co-trustees, as effectively as if given to each of them. Every instrument
appointing any separate trustee or co-trustee shall refer to this Indenture of
this Section.


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


                  Section 7.03 No Liability for Clean-up of Hazardous Materials.
In the event that the Trustee is required to acquire title to an asset for any
reason, or take any managerial action of any kind in regard thereto, in order to
carry out any fiduciary or trust obligation for the benefit of another, which in
the Trustee's sole discretion may cause the Trustee to be considered an "owner
or operator" under the provisions of the Comprehensive Environmental Response,
Compensation and Liability Act (CERCLA), 42 U.S.C. ss.9601, et seq., or
otherwise cause the Trustee to incur liability under CERCLA or any other
federal, state or local law, the Trustee reserves the right to, instead of
taking such action, either resign as Trustee or arrange for the transfer of the
title or control of the asset to a court appointed receiver.

                  (iv) to cure any ambiguity, to correct or supplement any
         provision herein which may be defective or inconsistent with any other

         matters or questions arising hereunder so long as any such action does
         not adversely affect the interests of the Holders of the Equipment
         Notes.

         after the date such principal or premium, if any, or interest becomes
         due and payable;


                  (ii) create any lien with respect to the Indenture Estate
         ranking prior to, or on a parity with, the security interest created by
         this Indenture except such as are permitted by this Indenture, or
         deprive any Holder of an Equipment Note of the benefit of the lien on
         the Indenture Estate created by this Indenture;






                                       25

to receive, and shall be fully protected in relying upon, an Opinion of Counsel
stating that the execution of any amendment, supplement or waiver authorized
pursuant to this Article VIII or Article V is authorized or permitted by this
Indenture. If in the opinion of the Trustee any document required to be executed
pursuant to the terms of Section 8.01 adversely affects any right, duty,
immunity or indemnity in favor of the Trustee under this Indenture, the Trustee
may in its discretion decline to execute such document.


                  Section 8.03 Request of Substance, Not Form. It shall not be
necessary for the consent of the holders of Equipment Notes under Section

but it shall be sufficient if such consent shall approve the substance thereof.


                  Section 8.04 Documents Mailed to Holders. Promptly after the
execution by the Trustee of any document entered into pursuant to Section
8.01(b), the Trustee shall mail, by first-class mail, postage prepaid, a

appropriate notation on any Equipment Note thereafter authenticated.
Alternatively, if the Company or the Trustee so determines, the Company in
exchange for such changed Equipment Note shall issue and the Trustee shall
authenticate a new Equipment Note that reflects the changed terms.

         Certificate shall include the basis for determination of such Fair
         Value), (B) whether such Replacement Item of Equipment is then subject

         reasonably require in order to assure that the Replacement Item of
         Equipment and the related Lease, if any, are duly and properly
         subjected to the Lien of this Indenture, to the same extent as the Item
         of Equipment replaced thereby and the related Lease, if any.


                  Section 9.12 Scope of Business Activities Abroad. The Company
shall not engage in any business activities within the territory of Mexico which
might result in the Company being subject to the Mexican Bankruptcy Law ("Ley de

the territory of Mexico and delivering to the Trustee an opinion of Mexican
counsel satisfactory to the Trustee as to the perfection and priority of such

(given at the request of a Majority in Interest), the Company shall cause any
and all of the Operative Agreements to be recorded with or under such system and
shall cause all other filings and recordings and all such other action required

                                    GUARANTEE











                  Section 10.01 Guarantee. (a) The Guarantor hereby
unconditionally guarantees to each Noteholder and to the Trustee and its
successors and assigns, irrespective of the validity and enforceability of this
Indenture, the Equipment Notes or the obligations of the Company hereunder or
thereunder, that:


                  (i) the principal of, premium, if any, and interest on the
         Equipment Notes will be promptly paid in full when due, and interest on
         the overdue principal of, premium, if any, and interest on the

         hereof and thereof; and


                  (ii) in case of any extension of time of payment or renewal of
         any Equipment Notes or any of such other obligations, that same will be
         promptly paid in full when due or performed in accordance with the
         terms of the extension or renewal.


                  Failing payment when due of any amount so guaranteed or any
performance so guaranteed for whatever reason, the Guarantor will pay or perform
the same immediately. The Guarantor agrees that this is a guarantee of payment
and not a guarantee of collection.


                  (b) The Guarantor hereby agrees that its obligations hereunder
are absolute and unconditional, irrespective of the validity, regularity or
enforceability of the Equipment Notes or this Indenture, the absence of any
action to enforce the same, any waiver or consent by any Noteholder with respect
to any provisions hereof or thereof, the recovery of any judgment against the
Company, any action to enforce the same or any other circumstance which might
otherwise constitute a legal or equitable discharge or defense of a guarantor.
The obligations of the Guarantor hereunder shall remain in full force and effect
until satisfaction of all obligations guaranteed by it hereunder and, without
limiting the generality of the foregoing, to the extent not 






                                       33











prohibited by applicable law, shall not be released, discharged or otherwise
affected by the existence of any claims, set-off, defense, counterclaim or other
rights that the Guarantor may have at any time and from time to time against any
Person, whether in connection herewith or with any unrelated transaction. The
Guarantor hereby waives diligence, presentment, demand of payment, filing of
claims with a court in the event of insolvency or bankruptcy of the Company, any
right to require a proceeding first against the Company, protest, notice and all
demands whatsoever and covenant that this Guarantee will not be discharged
except by complete performance of the obligations contained in the Equipment
Notes and this Indenture.

or otherwise to return to the Company, the Guarantor or any custodian, trustee,
liquidator or other similar official acting in relation to either the Company or
the Guarantor, any amount paid by either to the Trustee or such Noteholder, this
Guarantee, to the extent theretofore discharged, will be reinstated in full
force and effect.


                  (d) The Guarantor agrees that it will not be entitled to any
right of subrogation in relation to the Noteholders in respect of any
obligations guaranteed hereby until payment in full of all obligations
guaranteed hereby. The Guarantor further agrees that, as between the Guarantor,
on the one hand, and the Noteholders and the Trustee, on the other hand, (i) the
maturity of the obligations guaranteed hereby may be accelerated as provided in
Article IV hereof for the purposes of this Guarantee, notwithstanding any stay,
injunction or other prohibition preventing such acceleration in respect of the
obligations guaranteed hereby, and (ii) in the event of any declaration of
acceleration of such obligations as provided in Article IV hereof, such
obligations (whether or not due and payable) will forthwith become due and
payable by the Guarantor for the purpose of this Guarantee.


                  (e) The delivery of any Equipment Note by the Trustee, after
the authentication thereof hereunder, will constitute due delivery of the
Guarantee set forth in this Indenture on behalf of the Guarantor.


                  Section 10.02 Consolidation, Merger or Sale of Assets of
Guarantor. (a) The Guarantor covenants that it will not merge into or
consolidate with any other corporation or sell, convey or otherwise dispose of
all or substantially all of its assets to any Person unless (i) either (A) the
Guarantor shall be the continuing corporation or (B) the successor corporation
(if other than the Guarantor) shall be a corporation organized and existing
under the laws of the United States of America or a State thereof or the
District of Columbia, and such corporation shall expressly assume the due and
punctual performance and observance of all of the covenants and conditions of
this Indenture, the Equipment Notes, and the Guarantee to be performed by the
Guarantor on the terms set forth herein or therein by supplemental agreements
given by such successor corporation to the Guarantor; (ii) such successor
corporation shall make such filings and recordings as shall be necessary,
desirable or otherwise required to evidence such reorganization, consolidation,
merger, sale, conveyance or other disposition; (iii) immediately after giving
effect to such transaction, no Indenture Default or Indenture Event of Default
shall have occurred and be continuing solely as a result of such consolidation,
merger, sale, conveyance or other disposition and the Guarantor shall have
delivered to the Trustee an Officer's Certificate to such effect; (iv) in the
event that the Guarantor is not the surviving corporation, the Guarantor shall
have delivered to the Trustee an Officer's Certificate and an 






                                       34











opinion of counsel to such successor corporation, each stating that (x) such
consolidation, merger, sale, conveyance or other disposition and the assumption
agreement described in clause (i)(B) above comply with such clause (and in the
case of such certificate, clause (iii) of this Section 10.02(a)), (y) the
assumption agreement described in clause (i)(B) above is a legal, valid and
binding obligation of such successor corporation, and enforceable in accordance
with its terms except as such enforceability may be limited by bankruptcy,
reorganization, insolvency, moratorium and other similar laws and equitable
principles affecting the enforcement of creditors' rights generally, and (z) all
conditions precedent herein provided for relating to such transactions have been
complied with. 


                  (b) In case of any such merger, consolidation, sale,
conveyance or other disposition and upon any such assumption by the successor
corporation, such successor corporation shall succeed to and be substituted for
the Guarantor hereunder, with the same effect as if it had been named herein as
the party of the first part.


                                   ARTICLE XI


                                  MISCELLANEOUS


                  Section 11.01 Release of Property. With respect to each Item
of Equipment, this Indenture and the trusts created hereby shall terminate
without further action and this Indenture shall be of no further force or effect
upon the earliest to occur of (i) the release of such Item of Equipment from the
Lien of this Indenture by the Trustee pursuant to Section 2.12(a), 9.11 or 9.14,
(ii) the payment in full of the principal amount of, interest and any premium
on, all Equipment Notes outstanding hereunder and all other sums payable to the
Trustee and the Holders of the Equipment Notes hereunder and under such
Equipment Notes, and (iii) the date on which all conditions to the defeasance or
covenant defeasance of the Equipment Notes under Section 11.02(d) are satisfied.
The Trustee shall, upon the written request of the Company, execute and deliver
to, and at the expense of, the Person specified by the Company, an appropriate
instrument (in due form for recording) furnished by such Person to the Trustee,
releasing the appropriate Items of Equipment from the Lien of this Indenture.


                  Section 11.02 Defeasance and Covenant Defeasance. (a) The
Company may, at its option evidenced by a resolution of its board of directors
(or a duly constituted committee thereof) set forth in an Officer's Certificate,
at any time, elect to have either Section 11.02(b) or 11.02(c) be applied to all
outstanding Equipment Notes upon compliance with the conditions set forth below
in Section 11.02(d).


                  (b) Upon the Company's exercise under Section 11.02(a) of the
option applicable to this Section 11.02(b), each of the Company and the
Guarantor shall be deemed to have been discharged from its obligations with
respect to all outstanding Equipment Notes (including the Guarantee) on the date
the conditions set forth in Section 11.02(d) are satisfied (hereinafter,
"defeasance"). For this purpose, such defeasance means that the Company and the
Guarantor shall be deemed to have paid and discharged the entire indebtedness
represented by the outstanding Equipment Notes (including the Guarantee), which
shall thereafter be deemed to be "outstanding" only for the purposes of Section
11.02(e) and the other Sections of this 






                                       35











Indenture referred to in (i) and (ii) below, and to have satisfied all its other
obligations under such Equipment Notes, the Guarantee and this Indenture (and
the Trustee, on demand and at the expense of the Company, shall execute proper
instruments acknowledging the same), except for the following which shall
survive until otherwise terminated or discharged hereunder: (i) the rights of
Holders of outstanding Equipment Notes to receive, solely from the trust fund
described in Section 11.02(d), payments in respect of the principal of and
premium and interest on, such Equipment Notes when such payments are due, (ii)
the Company's obligations with respect to such Equipment Notes under Sections
2.03, 2.04, 2.05 and 2.06, (iii) the rights, powers, trusts, duties and
immunities of the Trustee hereunder and (iv) this Section 11.02.


                  (c) Upon the Company's exercise under Section 11.02(a) of the
option applicable to this Section 11.02(c), the Company shall be released from
its obligations under any covenant contained in Sections 9.04 through 9.14 and
the Guarantor shall be released from its obligation under Section 10.02 with
respect to the outstanding Equipment Notes on and after the date the conditions
set forth in Section 11.02(d) are satisfied (hereinafter, "covenant
defeasance"), and the Equipment Notes shall thereafter be deemed not to be
"outstanding" for the purposes of any direction, waiver, consent or declaration
or act of Holders (and the consequences of any thereof) in connection with such
covenants, but shall continue to be deemed "outstanding" for all other purposes
hereunder. For this purpose, covenant defeasance means that, with respect to the
outstanding Equipment Notes and the Guarantee, the Company and the Guarantor may
omit to comply with and shall have no liability in respect of any term,
condition or limitation set forth in any such covenant, whether directly or
indirectly , by reason of any reference elsewhere herein to any such covenant or
by reason of any reference in any such covenant to any other provision herein or
in any other document and such omission to comply shall not constitute an
Indenture Default or an Indenture Event of Default under Section 4.01, but,
except as specified above, the remainder of this Indenture and such Equipment
Notes shall be unaffected thereby.


                  (d) The following shall be the conditions to application of
either Section 11.02(b) or Section 11.02(c):


                  (i) The Company shall have irrevocably deposited with the
         Trustee as funds in trust, specifically pledged as security for, and
         dedicated solely to, the benefit of the Noteholders, (A) money in an
         amount, (B) U.S. Government Obligations that, through the payment of
         interest and principal in respect thereof in accordance with their
         terms, will provide (not later than one Business Day before the due
         date of any payment) money in an amount, or (C) a combination thereof,
         sufficient, in the opinion of a nationally recognized firm of
         independent certified public accountants expressed in a written
         certification thereof delivered to the Trustee, to pay the outstanding
         principal amount of and interest on all the Equipment Notes on the
         dates such amounts are due.

         Company shall have delivered to the Trustee an Opinion of Counsel to
         the effect that there has been a change in tax law since the date
         hereof or there has been published by the Internal Revenue Service a
         ruling to the effect that, and based thereon such Opinion of Counsel
         shall confirm that, the Noteholders and the holders of the Pass Through
         Certificates will not recognize income, gain or loss for United States
         Federal income tax purposes as a result 






                                       36











of the exercise by the Company of its option under Section 11.02(b) and
         will be subject to United States Federal income tax on the same amounts
         and in the same manner and at the same times as would have been the

                  (iii) In the case of an election under Section 11.02(c), the
         Company shall have delivered to the Trustee an Opinion of Counsel to
         the effect that the Noteholders and the holders of the Pass Through
         Certificates will not recognize income, gain or loss for United States
         Federal income tax purposes as a result of the exercise by the Company
         of its option under Section 11.02(c) and will be subject to United
         States federal income tax on the same amounts and in the same manner
         and at the same times as would have been the case if such option had
         not been exercised.


                  (iv) The Company shall have delivered to the Trustee an
         Opinion of Counsel to the effect that such defeasance trust does not
         constitute an "investment company" within the meaning of the Investment
         Company Act of 1940, as amended, and after the passage of 90 days
         following such deposit, such defeasance trust will not be subject to
         Section 547 of the U.S. Bankruptcy Code or Section 15 of the New York
         Debtor and Creditor Law.


                  (v) All other amounts then due and payable hereunder have been
         paid.


                  (vi) Such deposit will not result in a breach or violation of,
         or constitute a default or event of default under any other agreement
         or instrument to which the Company is a party or by which it is bound.


                  (vii) No Indenture Event of Default or Indenture Default shall
         have occurred and be continuing on the date of such deposit or at any
         time during the period ending on the 91st day after the date of such
         deposit.


                  (viii) The Company shall have delivered to the Trustee a

Obligations have been deposited pursuant to Section 11.02(d).


                  (g) If the Trustee is unable to apply any money in accordance

governmental authority enjoining, restraining or otherwise prohibiting such

Indenture and the Equipment Notes shall be revived and reinstated as though no
deposit had occurred pursuant to Section 11.02(b) or 11.02(c), as the case may
be, until such time as the Trustee is permitted to apply all such money in
accordance with Section 11.02(e); provided, however, that if the Company makes

accounting or to the transfer to it of legal title to any part of the Indenture
Estate.


                  Section 11.04 Sale of Items of Equipment by Trustee Is

Equipment Notes and the Company and shall be effective to transfer or convey all
right, title and interest of the Trustee, the Company and such Holders of the
Equipment Notes in and to the Equipment. No purchaser or other grantee shall be
required to inquire as to the authorization, necessity, expediency or regularity
of such sale or conveyance or as to the application of any sale or other
proceeds with respect thereto by the Trustee.


                  Section 11.05 Indenture and Equipment Notes for Benefit of the
Company, Guarantor, Trustee and Holders Only. Nothing in this Indenture, whether
express or implied, shall be construed to give to any Person other than the
Company, the Guarantor, the Trustee and the Holders of the Equipment Notes any
legal or equitable right, remedy or claim under or in respect of this Indenture
or any Equipment Note.


                  Section 11.06 Further Assurances. The Company and the
Guarantor will duly execute and deliver to the Trustee such further documents
and assurances and take such further action as may be necessary or as the
Trustee may from time to time reasonably request or as may be required by

purpose of this Indenture and to establish and protect the rights and remedies
created or intended to be created in favor of the Trustee hereunder.

additional certificate or opinion need be furnished.
