financial analysis and consulting, advisory services and costs of a similar
nature.

     (b)  Upon the consummation of the transactions contemplated by this
Agreement, the Lessee agrees to pay when due: (i) the reasonable expenses
(including reasonable legal fees and expenses) of the Owner Trustee, the
Indenture Trustee and the Participants incurred subsequent to the delivery of
the Equipment on the Closing Date, in connection with any supplements,
amendments, modifications, alterations, waivers or consents of any of the
Operative Agreements which are (1) requested by, or necessitated by action or
inaction on the part of, the Lessee or by any applicable law or regulation
(other than laws or regulations solely relating to the business of the Lessor or
the Owner Participant) or entered into in connection with, or as a result of, a
Lease Default or (2) necessary or required to effectuate the purpose or intent
of any Operative Agreement (including costs incurred in connection with any
adjustment pursuant to Section 2.6); (ii) the ongoing reasonable fees and

     (c)  If the transactions contemplated hereby are not consummated as a
result of (i) the Lessee's default in its obligations to consummate the

Notwithstanding anything contained herein to the contrary, if the transactions

<PAGE>

(x) the Owner Participant's default in its obligations to consummate the
transactions hereunder, or (y) the Owner Participant's failure to make its
equity investment as required by Section 2.2(a) after the conditions specified
in Section 4 have been satisfied or waived by it in writing (other than
conditions the satisfaction of which are solely in the control of the Owner
Participant), the Owner Participant shall pay all Transaction Costs other than
such costs and expenses that would otherwise benefit the Lessee in ultimately
closing the transaction.

     (d)  Notwithstanding the foregoing provisions of this Section 2.5, except
as specifically provided in Section 7.2 or in any other Operative Agreement, the
Lessee shall have no liability for any costs or expenses relating to any
voluntary transfer of the Owner Participant's interest in the Equipment
including any transfer prior to the Closing Date of the Owner Participant's
obligation to fund its participation pursuant to Section 2 (other than in
connection with any transfer pursuant to Sections 10.2, 11.4, 22.1 or 22.3 of
the Lease or Section 6.9 hereof or a Lease Event of Default) and no such costs
or expenses shall constitute Transaction Costs and the Lessee will not have any
obligation with respect to the costs and expenses resulting from any voluntary
transfer of any equity interest by any transferee of the Owner Participant,
whenever occurring (other than in connection with a Lease Event of Default).

     Section 2.6  Calculation of Adjustments to Basic Rent, Stipulated Loss
Value and Termination Value; Confirmation and Verification.

     (a)  Calculation of Adjustments. In the event that (A) the Closing Date is
other than April 13, 2000 or (B) the Transaction Costs paid by the Owner
Participant pursuant to Section 2.5 prior to the first Rent Payment Date are
less or more than $834,947.94 for the Equipment or (C) a refinancing
contemplated by Section 10.2 occurs, (D) any change in the Code which is enacted
and effective and/or any change in the income tax regulations which is
promulgated, adopted and effective prior to the Closing Date (provided the Owner
Participant or the Lessee shall have given notice of such change to the other
party prior to such Closing Date), which change alters or eliminates the tax
assumptions upon which the calculation of Basic Rent, Stipulated Loss Values,
Termination Values, Early Purchase Price and Basic Term Purchase Price were
based, or (E) the Equipment Cost or the composition of the Units is different
than as described on Schedule 1 hereto, or (F) the Debt Rate on, and
amortization of the Equipment Notes is different than the assumptions upon which
the calculations of the Basic Rent was based, then, in each such case, the Owner
Participant shall recalculate the payments or amounts, as the case may be, of
Basic Rent, Stipulated Loss Values, Termination Values, Early Purchase Price and
Basic Term Purchase Price, (i) to preserve the Net Economic Return that the
Owner Participant would have realized in the absence of the changes referred to
in Sections (A) through (F) of this Section 2.6(a) and (ii) to minimize to the
greatest extent possible, consistent with the foregoing clause (i), the present
value (discounted semiannually at an interest rate per annum equal to the Debt
Rate) of the payments of Basic Rent. Any such recalculation performed due to the
occurrence of an event described in clause (A), (B), (D), (E), and (F) above
shall be made prior to the first Rent Payment Date. In performing any such
recalculation and in determining the Owner Participant's Net Economic Return,
the Owner Participant shall utilize the same methods and assumptions originally
used in making the computations of Basic Rent, Stipulated Loss Values,
Termination Values, Early Purchase Price and Basic Term Purchase Price with
respect to the Basic Term initially set forth in Schedules 3, 4, 6 and 7 to this
Participation Agreement (other than those assumptions changed as a result of any
of the events described in

                                      7
<PAGE>

clauses (A) through (F) of the preceding sentence necessitating such
recalculation; it being agreed that such recalculation shall reflect solely any
changes of assumptions or facts resulting directly from the event or events
necessitating such recalculation). Such adjustments shall comply (to the extent
the original structure complied but allowing variations to reflect the event
giving rise to the adjustment) with Section 467 of the Code and any regulations
thereunder so as not to cause the Lease to be a "disqualified leaseback or long-
term agreement" within the meaning of Section 467 of the Code and any regulation
thereunder, and the requirements of Sections 4.02(5), 4.07(1) and (2) and
4.08(1) of Revenue Procedure 75-28, as amended, calculated, except in the case
of a refinancing pursuant to Section 10.2, without taking into account any
change after the Closing Date in or to Section 467 of the Code (and any
regulations thereunder) and such requirements of Revenue Procedure 75-28.

     (b)  Confirmation and Verification. Upon completion of any recalculation
described above in this Section 2.6, a duly authorized officer of the Owner
Participant shall provide a certificate to the Lessee either (x) stating that
the payments of Basic Rent, Stipulated Loss Values, Termination Values, Early
Purchase Price and Basic Term Purchase Price with respect to the Basic Term as
are then set forth in Schedules 3, 4, 6 and 7 of this Participation Agreement do
not require change, or (y) setting forth such adjustments to the payments of
Basic Rent, Stipulated Loss Values, Termination Values, Early Purchase Price or
Basic Term Purchase Price with respect to the Basic Term as have been calculated
by the Owner Participant in accordance with Section 2.6(a) above. Such
certificate shall describe in reasonable detail the basis for any such
adjustments, and any such adjustment and corresponding adjustments to the
Stipulated Loss Values, Termination Values, Early Purchase Price and Basic Term
Purchase Price will be computed on a basis consistent with that used by the
Owner Participant in the original calculation of Basic Rent. Any such adjustment
shall be deemed approved upon notice of such approval by the Lessee to the Owner
Participant or on the thirty-first (31st) day following delivery of such
certificate by the Owner Participant to the Lessee unless the Lessee, prior to
such day, requests verification pursuant to the following sentence, and shall
become effective as of the earlier of (i) the first Rent Payment Date and (ii)
the date the Lessee approves or has been deemed to have approved such adjustment
(except that any adjustment to Stipulated Loss Value shall be effective as of
the Closing Date). If the Lessee shall so request, the recalculation of any such
adjustments described in this Section 2.6 shall be verified on a confidential
basis by a nationally recognized firm of independent accountants selected by the
Owner Participant and reasonably acceptable to the Lessee and any such
recalculation of such adjustment as so verified shall be binding on the Lessee
and the Owner Participant. Such accounting firm shall be requested to make its
determination within 30 days. The Owner Participant shall provide to a
representative of such accounting firm, on a confidential basis, such
information as it may reasonably require, including the original assumptions
used by the Owner Participant and the methods used by the Owner Participant in
the original calculation of, and any recalculation of, Basic Rent, Stipulated
Loss Values, Termination Values, Early Purchase Price and Basic Term Purchase
Price and such other information as is necessary to determine whether the
computation is accurate and in conformity with the provisions of this Agreement,
provided that in no event shall the Owner Participant have any obligation to
provide the Lessee with any such information; and provided, further, that the
Owner Participant shall have no obligation to disclose to the Lessee, such
accounting firm or any other Person, or to permit the Lessee, such accounting
firm or any other Person, to examine any federal, state or local income tax
returns of the Owner Participant, or books or accounting records related
thereto, for any taxable year. Subject to the immediately following sentence,
the costs of

                                       8
<PAGE>

such verification shall be borne by the Lessee. If such accounting firm's
verification shall result in a decrease in the net present value (expressed as a
percentage of Total Equipment Cost) of the Basic Rent (discounted semiannually
at a rate per annum equal to the Debt Rate) under this Lease calculated as of
the Closing Date, as compared to the net present value of Basic Rent proposed by
the Owner Participant, by more than the greater of (a) 10 basis points or (b)
10% of the proposed adjustment, then the Owner Participant agrees to reimburse
the Lessee for any amounts paid for such verification. Any revised adjustment
resulting from such verification shall become effective on the next Rent Payment
Date after such verification has been concluded (except that any adjustment to
Stipulated Loss Value shall be effective as of the Closing Date), and shall take
into account any underpayment or overpayment, together with interest thereon at
the Debt Rate, resulting from an earlier effectiveness of the original
adjustment.

     (c)  Compliance. Notwithstanding the foregoing, any adjustment made to the
payments of Basic Rent, Stipulated Loss Values, Termination Values or Early
Purchase Price with respect to the Basic Term, pursuant to the foregoing, shall
comply with the following requirements: (i) each installment of Basic Rent, as
so adjusted, under any circumstances and in any event, will be in an amount at
least sufficient for the Owner Trustee to pay in full as of the due date of such
installment any payment of principal of and interest on the Equipment Notes
required to be paid on the due date of such installment of Basic Rent, and (ii)
Stipulated Loss Value, Termination Value and Early Purchase Price, as so
adjusted, under any circumstances and in any event, will be an amount which,
together with any other amounts required to be paid by the Lessee under the
Lease in connection with an Event of Loss or a termination of the Lease, as the
case may be, will be at least sufficient to pay in full, as of the date of
payment thereof, the aggregate unpaid principal of, any Make-Whole Amount and
all unpaid interest on the Equipment Notes, accrued to the date on which
Stipulated Loss Value, Termination Value or Early Purchase Price, as the case
may be, is paid in accordance with the terms of the Lease.

     (d)  Invoices. All invoices in respect of Transaction Costs to the extent
not delivered on the Closing Date shall be directed to the Owner Participant at
the address set forth in Section 10.4, with a copy to the Lessee.

     Section 2.7  Postponement of Closing Date.
                  ----------------------------

     (a)  The scheduled Closing Date may be postponed from time to time with
respect to all of the Units for any reason (but to no later than April 28, 2000)
if the Lessee gives the Owner Participant, the Indenture Trustee, the Pass
Through Trustee and the Owner Trustee telex, telegraphic, facsimile or
telephonic (confirmed in writing) notice of the postponement and notice of the
date to which such Closing Date has been postponed, the notice of postponement
to be received by each party no later than 5:30 p.m., New York City time, on the
originally scheduled Closing Date, and the term "Closing Date" as used in this
Agreement shall mean the postponed "Closing Date".

     (b)  In the event of any postponement of the originally scheduled Closing
Date pursuant to this Section 2.7 (the originally scheduled Closing Date being
referred to as the "Scheduled Closing Date" for the purposes of this Section
2.7): (i) the Lessee will reimburse the Owner Participant for the loss of the
use of its funds with respect to each such Unit occasioned by such postponement
or failure to deliver or accept (unless such failure to accept is caused by a

                                       9
<PAGE>

default by the Owner Participant hereunder or by the Owner Trustee (acting
pursuant to instructions from the Owner Participant) under the Trust Agreement,
the Lease or the Indenture) by paying to the Owner Participant on demand
interest at the Debt Rate, for the period from and including the Scheduled
Closing Date to but excluding the earlier of the date upon which such funds are
returned to the Owner Participant (unless such funds are returned after 1:00
p.m., New York City time, in which case such date of return shall be included)
or the actual Closing Date; provided that the Lessee shall in any event pay to
the Owner Participant at least one day's interest at the Debt Rate on the amount
of such funds, unless the Owner Participant shall have received, prior to 12:00
noon, New York City time, on the Business Day preceding the Scheduled Closing
Date, a notice of postponement of the Scheduled Closing Date pursuant to Section
2.7(a), and (ii) the Indenture Trustee will return not later than 10:00 a.m.,
New York City time, on the first Business Day following the Scheduled Closing
Date, any funds which it shall have received from the Owner Participant as its
Commitment for such Units, absent joint instructions from the Lessee and the
Owner Participant to retain such funds until the specified date of postponement
established under Section 2.7(a).

     (c)  The Indenture Trustee agrees that, in the event it has received
telephonic notice (to be confirmed promptly in writing) from the Lessee on the
Scheduled Closing Date that such Scheduled Closing Date is to be postponed, it
will if instructed in the aforementioned notice from the Lessee (which notice
shall specify the securities to be purchased) use reasonable best efforts to
invest, at the risk of the Lessee (except as provided below with respect to the
Indenture Trustee's gross negligence or willful misconduct), the funds received
by it from the Owner Participant with respect to its Commitment in Specified
Investments in accordance with the Lessee's instructions. Any such Specified
Investments purchased by the Indenture Trustee upon instructions from the Lessee
shall be held in trust by the Indenture Trustee (but not as part of the
Indenture Estate under the Indenture) for the benefit of the Owner Participant
whose funds are invested in Specified Investments upon instructions from the
Lessee and any net profits on the investment of such funds (including interest),
if any, shall be for the account of and shall on the Closing Date, or on the
date such funds are returned to the Owner Participant, be paid over to, the
Lessee. The Lessee shall pay to the Indenture Trustee on the Closing Date (if
such Unit or Units are delivered and accepted pursuant hereto) the amount of any
net loss on the investment of such funds invested at the instruction of the
Lessee. If the funds furnished by the Owner Participant with respect to such
Unit or Units are required to be returned to the Owner Participant, the Lessee
shall, on the date on which such funds are so required to be returned, reimburse
the Indenture Trustee, for the benefit of the Owner Participant, for any net
losses incurred on such investments. The Indenture Trustee shall not be liable
for failure to invest such funds or for any losses incurred on such investments
except for its own willful misconduct or gross negligence. In order to obtain
funds for the payment of Equipment Cost for such Unit or Units or to return
funds furnished by the Owner Participant to the Indenture Trustee for the
benefit of the Owner Participant with respect to such Unit or Units, the
Indenture Trustee is authorized to sell any Specified Investments purchased as
aforesaid with the funds received by it from the Owner Participant in connection
with such Unit or Units.

     (d)  Notwithstanding the provisions of Section 2.7(a), the Owner
Participant shall not be under any obligation to make its Commitment available
beyond 11:00 a.m., New York City time, on April 28, 2000.

the date hereof:

     (a) the Lessee is a corporation duly organized, validly existing, and in

in any court or before any governmental authority or arbitration board or
tribunal which individually or in the aggregate would, if determined adversely
to it, materially and adversely affect the financial condition or business of
the Lessee and its consolidated Subsidiaries, taken as a whole, or impair the
ability of the Lessee to perform its obligations under the Lessee Agreements or

otherwise, of the Lessee and its consolidated Subsidiaries, taken as a whole, as
shown on the financial statements of Lessee as of such date;

qualification with, or the giving of notice to, any trustee or any holder of
indebtedness of Lessee or any governmental authority on the part of the Lessee
is required in connection with the execution and delivery by the Lessee of the

delivered on the Closing Date and the Indenture Supplements in respect of the
Units delivered on the Closing Date will on or before the Closing Date be duly
filed with the STB pursuant to 48 U.S.C. (S)11301 and deposited with the
Registrar General of Canada pursuant to Section 105 of the Canada Transportation

and in the Units, and such deposit with the Registrar General of Canada will
perfect the Owner Trustee's and the Indenture Trustee's rights in such Operative
Agreements and in the Units and no other filing, recording or deposit with, or
giving of notice to any other federal, state, provincial or local government or
agency thereof, or any other action, is necessary in order to

<PAGE>

protect the rights of the Owner Trustee and the Indenture Trustee in such
Operative Agreements or in such Units in the United States, any state thereof,
the District of Columbia or to protect the rights of the Owner Trustee and the
Indenture Trustee in such Operative Agreements or in such Units in Canada or any

Participant to the extent of the interest transferred hereunder and under each
other Operative Agreement to which the Owner Participant is a party, and, except

                                      33

shall have been delivered to the Owner Participant, the Owner Trustee and the
Indenture Trustee an Officer's Certificate of the successor to the Lessee (or
such Person as is the surviving corporation) and an opinion of counsel (which
may be such Person's in-house counsel) in form and substance reasonably
satisfactory to the Owner Participant, the Owner Trustee and the Indenture
Trustee, each stating that such consolidation, merger, conveyance, transfer or
lease and the assumption agreement mentioned in clause (i) above comply with
this Section 6.8, and (v) if the Person (x) formed by such consolidation or
surviving such merger (if other than the Lessee) or the Person which acquires by
conveyance, transfer or lease of all or substantially all of the assets of the
Lessee is not an Affiliate of the Lessee, the aggregate net worth of such
surviving or acquiring Person immediately after such merger, consolidation or
acquisition (determined in accordance with generally accepted accounting
principles) is not less than the consolidated net worth of the Lessee
immediately prior to such merger, consolidation or acquisition, or (y) with
which Lessee consolidates or merges or which acquires by conveyance, transfer or
lease of all or substantially all of the assets of the Lessee is an Affiliate of
the Lessee, such Person, immediately prior to such consolidation, merger or
acquisition, has a positive net worth (determined in accordance with generally
accepted accounting principles). Upon such consolidation or merger, or any
conveyance, transfer or lease of all or substantially all of the assets of the
Lessee in accordance with this Section 6.8, the successor corporation formed by
such consolidation or into which the Lessee is merged or to which such
conveyance, transfer or lease is made shall succeed to, and be substituted for,
and may exercise every right and power of, the Lessee under this Agreement and
the other Operative Agreements with the same effect as if such successor
corporation had been named as the Lessee herein.

     Section 6.9  Lessee's Purchase in Certain Circumstances. If an Owner
Participant or any Affiliate thereof is or acquires, is acquired by, merges or
otherwise consolidates with any company or Affiliate thereof engaged in full
service railcar leasing, whether or not a direct competitor to the Lessee or any
Affiliate thereof, or any Person that has a material interest (whether held
directly or indirectly) in an enterprise that engages in a business that is
competitive with the Lessee's full service railcar leasing business, the Lessee
may, no later than one year after a Responsible Officer of the Lessee has actual
knowledge of such event, request that such Owner Participant transfer its
Beneficial Interest pursuant to Section 6.1. If such Owner Participant has not
transferred its Beneficial Interest within 180 days of such request, the Lessee
may, on a Determination Date which is designated by the Lessee by written notice
to the Owner Trustee and the Indenture Trustee not less than 25 days prior to
such Determination Date, purchase a number of the Units of Equipment equal to
the percentage of the Equipment that the portion of the Beneficial Interest held
by such Owner Participant bears to 100% of the Beneficial Interest for a
purchase price equal to the Termination Value for such Units calculated as of
such Determination Date, together with all other amounts due and owing by the
Lessee under the Operative Agreements with respect to such Units, including,
without limitation, all accrued and unpaid Basic Rent therefor as of such
Determination Date (exclusive of any in advance Basic Rent due on such date) and
any Make-Whole Amount then payable on the Equipment Notes pursuant to Section
2.10(c) of the Indenture with respect to such Units; provided, that an
institutional investor which is a passive investor in the financing of equipment
or facilities used in full service railcar leasing shall not, solely by reason
of such investment, be deemed to be engaged in such businesses; provided,
further, that none of any Owner Participant or Affiliate thereof shall be deemed
to (i) be engaged in full service railcar leasing or (ii) hold (directly or
indirectly) any material interest in any business that is competitive with the
Lessee's full service

                                      34
<PAGE>

railcar leasing business, solely by reason of any sale, lease or other
disposition (or any actions in furtherance of any of the foregoing), of any of
such Person's interest in any equipment or facilities directly or indirectly
owned, leased or otherwise controlled pursuant to any such Person's passive
investment in the financing of any such equipment or facilities used in full
service railcar leasing. In the event that such Owner Participant hereinabove
referred to holds less than 100% of the Beneficial Interest, the determination
as to which Units are to be purchased under this Section 6.9 shall be made on a
random or other basis (in each case reasonably acceptable to the Lessor) without
discrimination based on maintenance status, operating condition of the Units in
question or otherwise and the notice hereinabove referred to shall describe such
manner in which the Lessee proposes to determine which Units are to be purchased
hereunder.

     If the Lessee elects to exercise the purchase option provided for in this
Section 6.9, the Lessee shall, as the purchase price therefor, in the sole
discretion of the Lessee, either (i) pay the Termination Value, as specified in
the paragraph above, with respect to such Units, together with all other amounts
due and owing by the Lessee under the Operative Agreements, or (ii) pay the
difference between the Termination Value and the portion of the outstanding
principal amount of the Equipment Notes which relates to such Units as of the
Determination Date specified by the Lessee in the first sentence of this Section
6.9 and assume on a full resource basis, and indemnify the Lessor against, all
of the Owner Trustee's obligations under the Indenture in respect of such
portion of the indebtedness evidenced by such Equipment Notes; provided, that,
following such assumption, the purchased Units shall remain subject to the lien
of a separate indenture similar to the Indenture pursuant to Section 3.06 of the
Indenture. The Lessee will make the payments required by foregoing clause (i) or
assume such portion of the indebtedness evidenced by the Equipment Notes which
relates to such Units as provided in foregoing clause (ii) on the Determination
Date designated in the first sentence of Section 6.9 in immediately available
funds against delivery of a bill of sale transferring and assigning to the
Lessee all right, title and interest of the Lessor in and to the Units on an
"as-is" "where-is" basis and containing a warranty against Lessor's Liens. In
such event, the costs of preparing the bill of sale and all other documentation
relating to such purchase and the costs of any necessary filings related thereto
will be borne by the Lessee. If the Lessee shall fail to fulfill its obligations
under this second paragraph of Section 6.9, all of the Lessee's obligations
under the Lease and the Operative Agreements, including, without limitation, the
Lessee's obligation to pay installments of Rent, with respect to the Units in
question shall continue.

     Section 6.10  Owner Participant an Affiliate of Lessee. If at any time the
original or any successor Owner Participant shall be an Affiliate of the Lessee,
such Owner Participant and the Lessee agree that notwithstanding Section 9.05 of
the Indenture they will not vote its Beneficial Interest to modify, amend or
supplement any provision of the Lease or this Agreement or give, or permit the
Owner Trustee to give, any consent, waiver, authorization or approval thereunder
if any such action would adversely affect in a material manner the Indenture
Trustee or any holder of an Equipment Note unless such action shall have been
consented to by a Majority in Interest.

     Section 6.11  Corporate Existence; Place of Business. The Lessee shall at
all times maintain its corporate existence except as permitted by Section 6.8;
and it shall do or cause to be done all things necessary to preserve and keep in
full force and effect its corporate rights,

                                      35
<PAGE>

powers, privileges and franchises except for any corporate right, power,
privilege or franchise that it in good faith determines is no longer necessary
or desirable in the conduct of its business.

     Section 6.12  No Impairment of Warranties. From and after the Closing Date
and throughout the Lease Term, the Lessee shall not take any action (or fail to
take any action) if the result of such action (or failure to act) would abrogate
or invalidate or otherwise materially adversely affect the validity of any
warranties applicable to the Units which would otherwise be available with
respect to the Units.

 SECTION 7.  LESSEE'S INDEMNITIES.

     Section 7.1  General Tax Indemnity.

     (a) Tax Indemnitee Defined. For purposes of this Section 7.1, "Tax
Indemnitee" means the Owner Participant, its Affiliates, the Owner Trustee, the
Trust Company, the Indenture Trustee both in its individual capacity and as
trustee, the Pass Through Trustee both in its individual capacity and as
trustee, each of their respective successors or assigns permitted under the
terms of the Operative Agreements, any officer, director, employee or agent of
any of the foregoing, the Trust Estate and the Indenture Estate.

     (b) Taxes Indemnified. All payments by the Lessee to any Tax Indemnitee in
connection with the transactions contemplated by the Operative Agreements shall
be free of withholdings of any nature whatsoever (and at the time that the
Lessee is required to make any payment upon which any withholding is required
the Lessee shall pay an additional amount such that the net amount actually
received will, after such withholding and on an After-Tax Basis, equal the full
amount of the payment then due) and shall be free of expense to each Tax
Indemnitee for collection or other charges, provided, however, that no such
additional amounts shall be paid by the Lessee and the Lessee assumes no
responsibility regarding any withholdings (i) imposed by reason of any transfer
of the Equipment or any interest in the Operative Agreements by the Lessor or
the Owner Participant, (ii) imposed solely by reason of a nexus between the
affected Tax Indemnitee and the jurisdiction imposing such withholding which
nexus is unrelated to the transactions contemplated by the Operative Agreements,
or (iii) imposed by the United States by reason of the status of the Tax
Indemnitee as a foreign corporation or nonresident individual, provided,
further, however, that, notwithstanding the exclusions contained in the
preceding clauses (i) - (iii), Lessee agrees to pay an additional amount of Rent
such that the net amount actually received by the Indenture Trustee, after all
such withholding, is sufficient to pay the related amounts due on the Equipment
Notes and the Lessee shall be entitled to recover such amounts under the next
succeeding sentence. If, for any reason, the Lessee is required to make any
payment to a taxing authority with respect to, or as a result of, any
withholding tax imposed on any Tax Indemnitee in respect of the transactions
contemplated by the Operative Agreements which withholding tax is not the
responsibility of the Lessee under this Section 7.1 then such Tax Indemnitee
shall pay to the Lessee within 30 days of a demand an amount which equals the
amount paid by the Lessee with respect to, or as a result of, such withholding
tax, plus interest computed at such Tax Indemnitee's cost of funds rate during
the period commencing on the date the Lessee shall have paid an additional
amount pursuant to the first sentence of this paragraph and ending on the date
the Lessee actually receives such payment.

                                      36
<PAGE>

     Subject to the exclusions stated in subsection (c) below, the Lessee agrees
to indemnify and hold harmless each Tax Indemnitee, on an After-Tax Basis,
taking into account the income tax consequences to the Tax Indemnitee of the
accrual or receipt of an indemnity payment, against all fees (including, without
limitation, license, documentation or other fees and registration fees), taxes
(including, without limitation, income, gross receipts, franchise, sales, use,
rental, turnover, business, occupation, excise, value-added, tangible and
intangible personal property and stamp taxes), levies, assessments, imposts,
duties, charges or withholdings of any nature, together with any and all
penalties, additions to tax, fines or interest thereon ("Taxes") imposed upon
any Tax Indemnitee, the Lessee or any Person in possession of the Equipment or
all or any part of the Equipment by any federal, state or local government,
political subdivision, or taxing authority in the United States or its
possessions, by any government or taxing authority of or in a foreign country or
by any international authority, upon, with respect to or in connection with:

          (i) the Equipment or any part of any of the Equipment or interest
     therein;

          (ii)  acquisition, financing, ownership, leasing, possession,
     purchase, acceptance, rejection, condition, registration, return, use,
     storage, operation, return, transfer of title, maintenance, repair,
     improvement, replacement, substitution, delivery, redelivery, non-delivery,
     transport, preparation, assembly, insurance, construction, manufacture,
     insuring, modification, transfer, control, occupancy, servicing,
     mortgaging, location, refinancing, disposition, subleasing, repossession,
     abandonment, sale or other application or disposition of or with respect to
     the Equipment or any part of any of the Equipment or interest therein;

          (iii)  the rental payments, receipts on earnings arising from any Unit
     of Equipment or payable pursuant to the Lease;

          (iv)  the Equipment Notes, their issuance, acquisition, transfer or
     refinancing or (as between the Lessee and any Tax Indemnitee other than the
     Indenture Estate) the payment of principal, interest or premium or other
     amounts with respect thereto; and

          (v)  the Operative Agreements or otherwise in connection with the
     transactions contemplated thereby.

     (c)  Taxes Excluded. The indemnity provided for in paragraph (b) above
shall not extend to any of the following:

          (i)  In the case of the Owner Participant, the Owner Trustee or the
     Trust Estate, Income Taxes (as defined in Section 7.1(l), below) imposed by
     (A) the United States federal government (provided that this subclause (A)
     shall not be construed as preventing Lessee from recouping any such federal
     Income Taxes imposed by way of deduction or withholding from the Indenture
     Trustee, the Pass Through Trustee or any Certificateholder or as giving to
     the Indenture Trustee a right to indemnification by the Lessee for Taxes
     payable pursuant to Section 5.09 of the Indenture), (B) any state or local
     tax jurisdiction in the United States (unless such Tax Indemnitee would not
     have been subject to tax in such jurisdiction but for this transaction
     (including the operation or

                                       37
<PAGE>

     presence of any Unit (or part thereof) and other leasing transactions
     between the Lessee (or its Affiliates) and the Owner Participant (or its
     Affiliates) or the Lessee making payment from or performing other actions
     in such jurisdiction)), provided, that for purposes of determining whether
     any Tax Indemnitee would not have been subject to tax in such jurisdiction
     but for this transaction, the determination of (y) whether any Tax
     Indemnitee is treated as being incorporated or having its principal place
     of business in any state or local tax jurisdiction for purposes of this
     clause (B), or (z) whether any such Tax Indemnitee is deemed to be subject
     to tax in any state or local tax jurisdiction (and would have been subject
     to such tax without regard to this transaction) for purposes of this clause
     (B), shall be made by treating each corporation which is a Tax Indemnitee
     on a stand-alone basis and without regard to any Affiliates, related Tax
     Indemnitee or other entities, except to the extent that such Tax Indemnitee
     files combined or consolidated tax returns in such state or local
     jurisdiction, respectively, with one or more Affiliates which are also Tax
     Indemnitee, (C) any foreign government or any political subdivision or
     taxing authority thereof or any territory or possession of the United
     States or by any international authority except to the extent such Income
     Taxes would not have been imposed by such jurisdiction but for the use,
     location, operation, presence or registration of any Unit or part thereof
     in such jurisdiction or the activities of the Lessee or any of its
     Affiliates in such jurisdiction or the making of any payments from such
     jurisdiction by or on behalf of the Lessee pursuant to the Operative
     Agreements or any other nexus between such jurisdiction and the
     transactions contemplated by the Operative Agreements (other than such
     nexus as may result solely from the activities, presence, ownership or
     receipts of such Tax Indemnitee in each case unrelated to the Operative
     Agreements or transactions contemplated thereby) or (D) any government or
     jurisdiction described in (A), (B) or (C) of this clause (i) because the
     applicable Tax Indemnitee is not a resident of the United States for tax
     purposes.

          (ii)  Taxes imposed with respect to any period after the earliest of
     the applicable dates of (x) the return of possession of the Equipment to
     the Owner Participant or the placement of the Equipment in storage at the
     request of the Owner Participant, in either case pursuant to Section 6 of
     the Lease, (y) the termination of the Lease Term pursuant to Section 22.1
     or Section 22.3 of the Lease, or (z) the discharge in full of the Lessee's
     obligation to pay the Termination Value or the Stipulated Loss Value and
     all other amounts due, if any, under Section 10 or 11.2 of the Lease, as
     the case may be, with respect to the Equipment; provided that the exclusion
     set forth in this clause (ii) shall not apply to Taxes to the extent such
     Taxes relate to events occurring or matters arising prior to or
     simultaneously with the applicable time;

          (iii)  As to any Tax Indemnitee, Taxes to the extent caused by any
     misrepresentation or breach of warranty or covenant under the Operative
     Agreements by such Tax Indemnitee, or by the gross negligence or willful
     misconduct of such Tax Indemnitee;

          (iv)  As to any Tax Indemnitee, Taxes which become payable as a result
     of a sale, assignment, transfer or other disposition (whether voluntary or
     involuntary) by such Tax Indemnitee of all or any portion of its interest
     in the Equipment or any part thereof, the Trust Estate or any of the
     Operative Agreements or rights created thereunder other

                                       38
<PAGE>

     than as a result of the substitution, modification or improvement of the
     Equipment or any part thereof or a disposition which occurs as the result
     of the exercise of remedies for a Lease Event of Default, any disposition
     which occurs during the continuance of a Lease Event of Default or a
     purchase of any Unit pursuant to the Lease; provided, that, notwithstanding
     the foregoing but subject to the Tax Indemnity Agreement, Lessee shall not
     be obligated to indemnify any Tax Indemnitee with respect to net income
     taxes imposed within the United States as the result of a sale, assignment,
     transfer or other disposition by such Tax Indemnitee or any Taxes imposed
     as a result of the status of the Tax Indemnitee as other than a resident of
     the United States for tax purposes;

          (v)  Taxes which result from the Owner Trustee's engaging on behalf of
     the Trust Estate in transactions unrelated to those permitted or
     contemplated by the Operative Agreements;

          (vi)  As to any Tax Indemnitee, Taxes to the extent they exceed the
     Taxes that would have been imposed had the initial Tax Indemnitee not
     transferred, sold or otherwise disposed of any interest held by such Tax
     Indemnitee pursuant to any of the Operative Agreements such excess to be
     determined based on a certificate of the original Tax Indemnitee provided
     to the Lessee immediately prior to a transfer, sale or other such
     disposition of such interest, such certificate to set forth the state and
     local jurisdictions in which the original Tax Indemnitee would not be
     entitled to indemnification in accordance with (S) 7.1(c)(i)(B) and (C)
     hereof, provided, however, that this provision shall not apply to the
     determination of amounts required to make payments on an After-Tax Basis;
     and

          (vii)  Taxes imposed on the Owner Trustee based on the Owner Trustee's
     fee for services under the Trust Agreement.

     (d) All Tax Obligations in this Section, etC. Notwithstanding any other
provision anywhere contained in the Operative Agreements, it is understood that
except as provided in Section 6.2, with respect to the Owner Participant, and
Section 6.3, with respect to the Owner Trustee, and except as provided in
Section 5.03 of the Indenture, the Owner Participant and the Owner Trustee shall
have no obligations with respect to Taxes or other charges to the Indenture
Trustee or the Loan Participant imposed under Section 7.16 of the Pass Through
Trust Agreement or Section 5.09 of the Indenture, or otherwise.

     (e)  Payments to Lessee.

          (i)  If any Tax Indemnitee shall realize a Tax benefit (net of any Tax
     detriment not otherwise paid or indemnified against by the Lessee
     hereunder) as a result of any Taxes paid or indemnified against by the
     Lessee under this Section 7.1 (whether by way of deduction, credit,
     allocation or apportionment or otherwise), such Tax Indemnitee shall pay to
     the Lessee an amount equal to the amount of such Tax benefit, increased by
     the Tax Indemnitee's additional saved Taxes attributable to the payment
     being made to the Lessee hereunder; provided, however, that in no event
     shall the aggregate amount paid by any Tax Indemnitee to the Lessee with
     respect to any realized Tax benefit exceed the aggregate amount previously
     advanced by the Lessee with respect to such Taxes (in each case, computed
     on a pre-tax basis) but provided, further, that such excess shall be
     carried

                                       39
<PAGE>

     forward to reduce or offset any future obligations of the Lessee to such
     Tax Indemnitee under this Section 7.1.

          (ii)  Upon receipt by a Tax IndemnItee of a refund or credit of all or
     part of any Taxes paid or indemnified against by the Lessee, such Tax
     Indemnitee shall pay to the Lessee an amount equal to the amount of such
     refund plus any interest received by or credited to such Tax Indemnitee
     with respect to such refund increased or decreased, as the case may be, by
     the Tax Indemnitee's net additional or saved taxes attributable to the
     receipt of such amounts from the taxing authority and the payment being
     made to the Lessee hereunder.

          (iii)  The Tax Indemnitee shall in good faith file its Tax returns and
     deal with taxing authorities to seek and claim any such tax benefits or
     refunds.

          (iv)  Any disallowance or other loss of a tax refund, credit, savings
     or other benefit by a Tax Indemnitee, which refund, credit, savings or
     other benefit was taken into account under this Section 7.1, shall be
     treated as a tax indemnifiable by the Lessee under this Section 7.1 without
     regard to the exclusions in Section 7.1(c) (other than clause (iii).

     (f)  Procedures. Any amount payable to a Tax Indemnitee pursuant to
paragraph (b) shall be paid within 30 days after receipt of a written demand
therefor from such Tax Indemnitee accompanied by a written statement describing
in reasonable detail the basis for such indemnity and the computation of the
amount so payable, provided that such amount need not be paid prior to (i) the
date which is the Business Day before the date on which such Taxes are due (but
in no event before the taxable year of the Tax Indemnitee in which such Taxes
are due), or (ii) in the case of amounts which are being contested pursuant to
paragraph (g) hereof, subject to the requirement of an advance in clause (vi) of
the second paragraph of paragraph (g) hereof, the time such Taxes are due and
payable pursuant to the resolution of such contest (including all appeals). Any
amount payable to the Lessee pursuant to paragraph (e) shall be paid within 30
days after the Tax Indemnitee realizes a net tax benefit or receives a refund
giving rise to a payment under paragraph (e), and shall be accompanied by a
written statement by the Tax Indemnitee setting forth in reasonable detail the
basis for computing the amount of such payment. Within 15 days following the
Lessee's receipt of any computation from the Tax Indemnitee, the Lessee may
request that the accounting firm that regularly prepares the certified financial
statements of the Tax Indemnitee determine whether such computations of the Tax
Indemnitee are correct. Such accounting firm shall be requested to make the
determination contemplated by this paragraph (f) within 30 days of its
selection. In the event such accounting firm shall determine that such
computations are incorrect, then such firm shall determine what it believes to
be the correct computations. The Tax Indemnitee shall cooperate with such
accounting firm and supply it with all information necessary to permit it to
accomplish such determination on a confidential basis. The computations of such
accounting firm shall be final, binding and conclusive upon the parties and the
Lessee shall have no right to inspect the books, records or tax returns of the
Tax Indemnitee to verify such computation or for any other purpose. All fees and
expenses of the accounting firm payable under this Section 7.1(f) shall be borne
by the Lessee except that if such accounting firm determines that the Tax
Indemnitee's computations were incorrect and understated the payments owing to
the Lessee or overstated the payments owing to such Tax Indemnitee by 10% or
more of the correct amount as determined by

                                       40
<PAGE>

such accounting firm, then the Tax Indemnitee shall bear the fees and expenses
of such accounting firm.

     (g)  Contest. If a written claim is made against a Tax Indemnitee for Taxes
with respect to which the Lessee may be liable for indemnity hereunder, the Tax
Indemnitee shall give the Lessee prompt notice in writing of such claim (and in
any event within 30 days after its receipt) and shall promptly furnish the
Lessee with copies of the claim and all other writings received from the taxing
authority relating to the claim; provided however, that the failure of such Tax
Indemnitee timely to provide such written notice shall not affect the Lessee's
obligations under this Section 7.1(g) except to the extent that the same
materially adversely affects the ability of the Lessee to contest such Taxes.
The Tax Indemnitee shall not pay such claim prior to 30 days after providing the
Lessee with such written notice, unless required to do so by law or unless
deferral of payment might, in the reasonable good faith judgment of the Tax
Indemnitee, cause material adverse consequences to the Tax Indemnitee or result
in the creation of any Lien other than a Permitted Lien. The Tax Indemnitee
shall in good faith, with due diligence and at the Lessee's expense, if
requested in writing by the Lessee, contest (including pursuing all appeals
permitted hereby) in the name of the Tax Indemnitee (or, if requested by the
Lessee and permissible as a matter of law, in the name of the Lessee), or shall
permit the Lessee to contest in either the name of the Lessee or with the Tax
Indemnitee's consent, in the name of the Tax Indemnitee the validity,
applicability or amount of such Taxes by,

          (i) resisting payment thereof if practical;

          (ii)  not paying the same except under protest if protest is necessary
     and proper;

          (iii)  if the payment be made, using reasonable efforts to obtain a
     refund thereof in appropriate administrative and judicial proceedings; or

          (iv)  taking such other reasonable action as is reasonably requested
     by the Lessee from time to time.

provided, however, that to the extent the contest is carried on in the name of
the Lessee or an Affiliate, or is brought in the name of a Tax Indemnitee and
involves only Taxes for which the Lessee is or will be liable hereunder, such
contest shall be undertaken by the Lessee at the Lessee's expense (unless at any
time the Tax Indemnitee determines in its reasonable good faith judgment that
based upon the Lessee's conduct of such contest the Lessee's control of such
contest would cause material adverse consequences or a material risk thereof to
the Tax Indemnitee) and at no-after-tax cost to any Tax Indemnitee (a "Lessee
Controlled Contest"), but if such contest would involve any other Taxes or any
Taxes in the nature of a tax on net income then such Tax Indemnitee may in its
sole discretion control such contest (including selecting the forum for such
contest) (an "Indemnified Person Controlled Contest").

     In no event shall any Tax Indemnitee be required or the Lessee be permitted
to contest any Taxes for which the Lessee is obligated to indemnify pursuant to
this Section unless: (i) such Lessee shall have acknowledged its liability to
such Tax Indemnitee for an indemnity payment pursuant to this Section as a
result of such claim if and to the extent such Indemnitee or

                                       41
<PAGE>

the Lessee, as the case may be, shall not prevail in the contest of such claim;
(ii) such Tax Indemnitee shall have received the opinion of tax counsel (which
may, in the case of Taxes imposed by a taxing authority located in the United
States, include in-house counsel of the Lessee) selected by the Lessee and
satisfactory to the Tax Indemnitee furnished at Lessee's sole expense, to the
effect that a reasonable basis consistent with ABA Opinion 85-352 exists for
contesting such claim or, in the event of an appeal, that it is more likely than
not that an appellate court will reverse or substantially modify the adverse
determination (and provided that no appeal shall be required to the United
States Supreme Court); (iii) the Lessee shall have agreed to pay such Tax
Indemnitee on demand (and at no after-tax cost to any Tax Indemnitee) all
reasonable costs and expenses that such Tax Indemnitee actually incurs in
connection with contesting such claim (including, without limitation, all costs,
expenses, reasonable legal and accounting fees, disbursements, penalties,
interest and additions to the Taxes); (iv) no Lease Event of Default shall have
occurred and shall be continuing; (v) such Tax Indemnitee shall have determined
that the action to be taken will not result in any risk of imposition of
criminal penalties or substantial danger of sale, forfeiture or loss of, or the
creation of any Lien (except if such Lessee shall have adequately bonded such
Lien or otherwise made provision to protect the interests of such Tax Indemnitee
in a manner reasonably satisfactory to such Tax Indemnitee) on the Equipment or
any portion thereof or any interest therein; and (vi) if such contest shall be
conducted in a manner requiring the payment of the claim, the Lessee shall have
paid the amount required (at no after-tax cost to such Tax Indemnitee). The
Lessee shall cooperate with the Tax Indemnitee with respect to any contest
controlled and conducted by the Tax Indemnitee and the Tax Indemnitee shall
consult with the Lessee regarding the conduct of such contest. The Tax
Indemnitee shall cooperate with the Lessee with respect to any contest
controlled and conducted by the Lessee and the Lessee shall consult with the Tax
Indemnitee regarding the conduct of such contest.

     In no event will a Tax Indemnitee be required to contest in an Indemnified
Person Controlled Contest any Taxes if such Tax Indemnitee shall waive its right
to an indemnity under this Section 7.1 except that a Tax Indemnitee shall not be
permitted to waive or not contest any Lessee Controlled Contest without Lessee's
consent. Unless a Tax Indemnitee obtains the consent of the Lessee, which
consent shall not be unreasonably withheld (provided, however, the Lessee shall
not be considered to have unreasonably withheld such consent because of (i) any
failure by the Lessee to consider any issue or dispute of the Tax Indemnitee not
directly related to the claim giving rise to the contest rights in issue or (ii)
the Lessee's consideration of the effects of such settlement on issues of the
Lessee which are not the subject of such claim), the failure to contest or the
settlement of any contest required under Section 7.1 by a Tax Indemnitee shall
constitute a waiver by such Tax Indemnitee of its rights to indemnification
hereunder as to such contest and as to any future claims for which the Lessee's
right to contest shall have been precluded by such Tax Indemnitee' failure to
contest.

     (h)  For purposes of this Section 7.1, in determining the order in which
any Tax Indemnitee utilizes withholding or other foreign taxes as a credit
against such Tax Indemnitee's United States income taxes, such Tax Indemnitee
shall be deemed to utilize (i) first, all foreign taxes other than those
described in clause (ii) below; provided, however, that such other foreign taxes
which are carried back to the taxable year for which a determination is being
made (other than any carrybacks which are known to be available at the time such
determination is made) pursuant to this clause (i) shall be deemed utilized
after the foreign taxes described in clause (ii) below, and (ii) then, on a pro
rata basis, all foreign taxes (including fees, taxes and other charges

                                       42
<PAGE>

hereunder) with respect to which such Tax Indemnitee is entitled to obtain
indemnification pursuant to an indemnification provision contained in any lease,
loan agreement, financing document or participation agreement (including the
Lease).

     (i)  In the event any reports with respect to Taxes are required to be
made, the Lessee will either prepare and file such reports (and in the case of
reports which are required to be filed on the basis of individual items of
Equipment, such reports shall be prepared and filed in such manner as to show as
required the interests of each Tax Indemnitee in such item of Equipment) or, if
it shall not be permitted to file the same, it will notify each Tax Indemnitee
in writing of such reporting requirements, prepare such reports in such manner
as shall be reasonably satisfactory to each Tax Indemnitee and deliver the same
to each Tax Indemnitee within a reasonable period prior to the date the same is
to be filed. The Lessee shall provide such information as the Owner Participant
or the Lessor may reasonably require from the Lessee to enable the Owner
Participant and the Lessor to pursue or fulfill their respective tax filing, tax
audit, and tax litigation rights and obligations.

     (j)  The provisions of this Section 7.1 shall continue in full force and
effect, notwithstanding the expiration or termination of any Operative
Agreement, until all obligations hereunder have been met and all liabilities
hereunder paid in full.

     (k)  Any amount payable to the Lessee pursuant to the terms of this Section
7.1 shall not be paid or retained by the Lessee if at the time of such payment
or retention a Material Default or a Lease Event of Default shall have occurred
and be continuing. Such otherwise paid or retained amounts may be applied by the
related Tax Indemnitee to satisfy the obligations of the Lessee under the
Operative Agreements. At such time as there shall not be continuing any such
Material Default or Lease Event of Default, such amount shall be paid to the
Lessee without interest to the extent not previously applied in accordance with
the preceding sentence.

     (l)  For purposes of this Section 7.1, the term "Income Tax" means any Tax
based on or measured by or with respect to gross, adjusted gross or net income
(including without limitation, capital gains taxes, minimum taxes and tax
preferences) or gross or net receipts and Taxes which are capital, net worth,
conduct of business, franchise or excess profits taxes and interest, additions
to tax, penalties, or other charges in respect thereof (provided, however, that
sales, use, rental, excise, or property taxes shall not constitute an Income
Tax; and provided, further, that a value-added tax shall constitute an Income
Tax if it is in the nature of a tax on net income but shall not constitute an
Income Tax if it is in the nature of a sales, use, rental, excise, property or
other tax; and provided, further, that a withholding tax shall not constitute an
Income Tax notwithstanding its being a tax that is based on or measured by or
with respect to gross income or gross receipts).

     (m)  Withholding. The Pass Through Trustee shall withhold any Taxes
required to be withheld on payments to any holder of a Pass Through Certificate
who is a Non-U.S. Person except to the extent that such a holder of a Pass
Through Certificate has furnished evidence to the Pass Through Trustee
sufficient under applicable law to entitle such holder of a Pass Through
Certificate to any exemption from or reduction in the rate of withholding on
interest claimed by such holder of a Pass Through Certificate. The Indenture
Trustee shall withhold any Taxes required to be withheld on any payment to a
Holder pursuant to Section 5.09 of the Indenture. If

                                       43
<PAGE>

the Indenture Trustee or Pass Through Trustee fails to withhold a Tax required
to be withheld with respect to any Certificateholder or any claim is otherwise
asserted by a taxing authority against the Owner Trustee or Owner Participant
for any withholding tax, the Lessee will indemnify the Owner Trustee and the
Owner Participant (without regard to the exclusions set forth in Section 7.1(c)
hereof) on an After-Tax Basis against any such Taxes required to be withheld and
any interest and penalties with respect thereto, along with any other reasonable
out-of-pocket costs (including reasonable attorney's fees) incurred in
connection with any such claim. The Indenture Trustee or the Pass Through
Trustee, as the case may be, in its individual capacity (and without recourse to
the Indenture Estate), shall indemnify the Lessee (without regard to the
exclusions set forth in Section 7.1(c) hereof) on an After-Tax Basis for any
payment the Lessee shall have made pursuant to the preceding sentence.

     Section 7.2    General Indemnification and Waiver of Certain Claims.
                    ----------------------------------------------------

     (a)  Claims Defined. For the purposes of this Section 7.2, "Claims" shall
mean any and all costs, expenses, liabilities, obligations, losses, damages,
penalties, actions or suits or claims of whatsoever kind or nature (whether or
not on the basis of negligence, strict or absolute liability or liability in
tort) which may be imposed on, incurred by, suffered by, or asserted against an
Indemnified Person, as defined herein, or any Unit and, except as otherwise
expressly provided in this Section 7.2, shall include, but not be limited to,
all reasonable out-of-pocket costs, disbursements and expenses (including legal
fees and expenses) paid or incurred by an Indemnified Person in connection
therewith or related thereto.

     (b)  Indemnified Person Defined. For the purposes of this Section 7.2,

Affiliates and each of their respective directors, officers, employees,
successors and permitted assigns, agents and servants, the Trust Estate and the
Indenture Estate (the respective directors, officers, employees, successors and
permitted assigns, agents and servants of the Owner Participant, the Owner
Trustee, the Trust Company, the Indenture Trustee, the Pass Through Trustee and
each of their Affiliates, as applicable, together with the Owner Participant,
the Owner Trustee, the Indenture Trustee, the Pass Through Trustee and each of
their Affiliates, as the case may be, being referred to herein collectively as
the "Related Indemnitee Group" of the Owner Participant, the Indenture Trustee,
the Owner Trustee and the Pass Through Trustee, respectively).

     (c)  Claims Indemnified. Whether or not any Unit is accepted under the
Lease, or a closing occurs with respect thereto, and subject to the exclusions
stated in subsection (d) below, Lessee agrees to indemnify, protect, defend and
hold harmless each Indemnified Person on an After-Tax Basis against Claims
directly or indirectly resulting from or arising out of or alleged to result
from or arise out of (whether or not such Indemnified Person shall be
indemnified as to such Claim by any other Person):

          (i)  this Agreement or any other Operative Agreement or any of the
     transactions contemplated hereby and thereby or any Unit or the ownership,
     lease, operation, possession, modification, improvement, abandonment, use,
     non-use, maintenance, sublease, substitution, control, repair, storage,

                                       44
<PAGE>

     of any Unit (including, without limitation, injury, death or property
     damage of passengers, shippers or others, and environmental control, noise
     and pollution regulations, or the presence, discharge, spillage, release or
     escape of Hazardous Substances or damage to the environment (including,
     without limitation, clean-up costs, response costs, costs of corrective
     actions and natural resource damages)) whether or not in compliance with
     the terms of the Lease, or by any of the commodities, items or materials
     from time to time contained in any Unit, whether or not in compliance with
     the terms of the Lease, or by the inadequacy of any Unit or deficiency or
     defect in any Unit or by any other circumstances in connection with any
     Unit, or by the performance of any Unit or any risks relating thereto, or
     by any interruption of service, loss of business or anticipated profits or
     consequential damages;

          (ii)  the construction, manufacture, financing, refinancing, design,
     purchase, acceptance, rejection, delivery, non-delivery or condition of any
     Unit (including, without limitation, latent and other defects, whether or
     not discoverable, and any claim for patent, trademark or copyright
     infringement);

          (iii)  any act or omission (whether negligent or otherwise) or any
     breach of or failure to perform or observe, or any other non-compliance
     with, any covenant, condition or agreement to be performed by, or other
     obligation of, Lessee under any of the Operative Agreements, or the falsity
     of any representation or warranty of the Lessee in any of the Operative
     Agreements or in any document or certificate delivered in connection
     therewith other than representations and warranties in the Tax Indemnity
     Agreement;

          (iv)  the offer, sale or delivery of any Equipment Notes or Pass
     Through Certificates or any interest in the Trust Estate;

          (v)  any violation of law, rule, regulation or order by the Lessee or
     any sublessee or their respective directors, officers, employees, agents or
     servants; and

          (vi)  the acquisition or holding of any Equipment Notes or Pass
     Through Certificates being deemed to result in a "prohibited transaction"
     under ERISA or the Code.

     (d)  Lessee's Claims Excluded. The following are excluded from the
agreement to indemnify under this Section 7.2:

          (i)  Claims with respect to any Unit to the extent attributable to
     acts or events occurring after (A) in the case of the exercise by the
     Lessee of a purchase option with respect to such Unit under Section 22.1 or
     22.3 of the Lease, the exercise by the Lessee of an early termination
     option with respect to such Unit under Section 10 of the Lease, the
     occurrence or deemed occurrence of an Event of Loss with respect to such
     Unit under Section 11 of the Lease, or the election to replace such Unit
     under Section 8.1(b), 8.3 or 9.1 of the Lease, the last to occur of (x) the
     payment of all amounts due from the Lessee in connection with any such
     event, (y) the release of the Lien of the Indenture on such Unit, and (z)
     legal transfer of title to such Unit to any Person other than Lessor,
     except in

                                       45
<PAGE>

     the case of a retention of any Unit by Lessor pursuant to the terms and
     provisions of Section 10.3 of the Lease, and in the case of any such
     retention, upon the effective date of the termination of the Lease Term
     with respect to such Unit retained by Lessor pursuant to Section 10.3 or
     (B) in all other cases (except in any case where remedies are being
     exercised under Section 15 of the Lease), the last to occur of (x) with
     respect to such Unit, the earlier to occur of the termination of the Lease
     or the expiration of the Lease Term in accordance with the terms thereof,
     (y) with respect to each Unit, the return of such Unit to the Lessor in
     accordance with the terms of the Lease (it being understood that, so long
     as any Unit is in storage as provided in Section 6.1(c) of the Lease, the
     date of return thereof for the purpose of this clause (B) shall be the last
     day of the Storage Period), and (z) the release of the Lien of the
     Indenture on such Unit;

          (ii)  Claims which are Taxes, whether or not the Lessee is required to
     indemnify therefor under Section 7.1 hereof or the Tax Indemnity Agreement;

          (iii)  with respect to any particular Indemnified Person, Claims to
     the extent resulting from (x) the gross negligence or willful misconduct of
     such Indemnified Person, or (y) any breach of any covenant to be performed
     by such Indemnified Person under any of the Operative Agreements, or the
     falsity of any representation or warranty of such Indemnified Person in any
     of the Operative Agreements or in a document or certificate delivered in
     connection therewith;

          (iv)  any Claim to the extent attributable to any transfer by the
     Lessor of the Equipment or any portion thereof or any transfer by the Owner
     Participant of all or any portion of its interest in the Trust Estate other
     than (A) any transfer after a Lease Default or Lease Event of Default, (B)
     the transfer of the Equipment or any Owner Participant's interest in the
     Equipment to the Lessee, (C) the transfer of the Equipment to a third party
     pursuant to Lessee's election to terminate the Lease or (D) any transfer of
     the Equipment pursuant to Section 6.9;

          (v)  with respect to any particular Indemnified Person, any Claim
     resulting from the imposition of any Lessor's Lien attributable to such
     Indemnified Person; or

          (vi)  with respect to any particular Indemnified Person, any Claim, to
     the extent the risk thereof has been expressly assumed by such Indemnified
     Person in connection with the exercise by such Indemnified Person of the
     right of inspection or restenciling granted under Section 6.1 of the Lease
     or right of inspection granted under Sections 6.2 or 13.2 of the Lease.

     (e)  Insured Claims. In the case of any Claim indemnified by the Lessee
hereunder which is covered by a policy of insurance maintained by the Lessee
pursuant to Section 12 of the Lease or otherwise, each Indemnified Person agrees
to provide reasonable cooperation to the insurers in the exercise of their
rights to investigate, defend or compromise such Claim as may be required to
retain the benefits of such insurance with respect to such Claim.

     (f)  Claims Procedure. An Indemnified Person shall, after obtaining
knowledge thereof, promptly notify the Lessee of any Claim as to which
indemnification is sought;

                                       46
<PAGE>

provided, however, that the failure to give such notice shall not release the
Lessee from any of its obligations under this Section 7.2, except to the extent
that failure to give notice of any action, suit or proceeding against such
Indemnified Person shall have a material adverse affect on Lessee's ability to
defend such Claim or recover proceeds under any insurance policies maintained by
Lessee hereunder. The Lessee shall, after obtaining knowledge thereof, promptly
notify each Indemnified Person of any indemnified Claim affecting such Person.
Subject to the provisions of the following paragraph, the Lessee shall at its
sole cost and expense be entitled to control, and shall assume full
responsibility for, the defense of such claim or liability; provided that the
Lessee shall keep the Indemnified Person which is the subject of such proceeding
fully apprised of the status of such proceeding and shall provide such
Indemnified Person with all information with respect to such proceeding as such
Indemnified Person shall reasonably request.

     Notwithstanding any of the foregoing to the contrary, the Lessee shall not
be entitled to control and assume responsibility for the defense of such claim
or liability if (1) a Lease Event of Default shall have occurred and be
continuing, (2) such proceeding will involve any material danger of the sale,
forfeiture or loss of, or the creation of any Lien (other than any Lien
permitted under the Operative Agreements or a Lien which is adequately bonded to
the satisfaction of such Indemnified Person) on, any Unit, (3) the amounts
involved, in the good faith opinion of such Indemnified Person, are likely to
have a materially adverse effect on the business of such Indemnified Person
other than the ownership, leasing and financing of the Equipment, (4) in the
good faith opinion of such Indemnified Person, there exists an actual or
potential conflict of interest such that it is advisable for such Indemnified
Person to retain control of such proceeding or (5) such claim or liability
involves the possibility of criminal sanctions or liability to such Indemnified
Person. In the circumstances described in clauses (1) - (5), the Indemnified
Person shall be entitled to control and assume responsibility for the defense of
such claim or liability at the expense of the Lessee. In addition, any
Indemnified Person may participate in any proceeding controlled by the Lessee
pursuant to this Section 7.2, at its own expense, in respect of any such
proceeding as to which the Lessee shall have acknowledged in writing its
obligation to indemnify the Indemnified Person pursuant to this Section 7.2, and
at the expense of Lessee in respect of any such proceeding as to which the
Lessee shall not have so acknowledged its obligation to the Indemnified Person
pursuant to this Section 7.2. Lessee may in any event participate in all such
proceedings at its own cost. Nothing contained in this Section 7.2(f) shall be
deemed to require an Indemnified Person to contest any Claim or to assume
responsibility for or control of any judicial proceeding with respect thereto.

     (g)  Subrogation. If a Claim indemnified by the Lessee under this Section
7.2 is paid in full by the Lessee and/or an insurer under a policy of insurance
maintained by the Lessee, the Lessee and/or such insurer, as the case may be,
shall be subrogated to the extent of such payment to the rights and remedies of
the Indemnified Person (other than under insurance policies maintained by such
Indemnified Person) on whose behalf such Claim was paid with respect to the
transaction or event giving rise to such Claim. So long as no Lease Event of
Default shall have occurred and be continuing, should an Indemnified Person
receive any refund, in whole or in part, with respect to any Claim paid by the
Lessee hereunder, it shall promptly pay over the amount refunded (but not in
excess of the amount the Lessee or any of its insurers has paid) to the Lessee.

                                       47
<PAGE>

     (h)  Waiver of Certain Claims. The Lessee hereby waives and releases any
Claim now or hereafter existing against any Indemnified Person arising out of
death or personal injury to personnel of the Lessee, pollution incidents, loss
or damage to property of the Lessee, or the loss of profits or use of any
property of the Lessee, which may result from or arise out of the condition, use
or operation of the Equipment during the Lease Term, including without
limitation any latent or patent defect whether or not discoverable.

     (i)  No Guaranty. The general indemnification provisions of this Section
7.2 do not constitute a guaranty by the Lessee that the principal of, interest
on or any amounts payable with respect to the Equipment Notes will be paid.

 SECTION 8.    LESSEE'S RIGHT OF QUIET ENJOYMENT.

     Each party to this Agreement acknowledges notice of, and consents in all
respects to, the terms of the Lease, and expressly, severally and as to its own
actions only, agrees that, so long as no Lease Event of Default has occurred and
is continuing, it shall not take or cause to be taken any action contrary to
Lessee's rights under the Lease, including, without limitation, the right to
possession, use and quiet enjoyment by Lessee or any permitted sublessee of the
Equipment.

 SECTION 9.    SUCCESSOR INDENTURE TRUSTEE.

     In the event that the Indenture Trustee gives notice of its resignation
pursuant to Section 8.02 of the Trust Indenture, the Owner Trustee shall
promptly appoint a successor Indenture Trustee reasonably acceptable to the
Lessee and the Pass Through Trustee.

 SECTION 10.   MISCELLANEOUS.

     Section 10.1  Consents. Each Participant covenants and agrees (subject, in
the case of the Loan Participant, to all of the terms and provisions of the
Trust Indenture) that it shall not unreasonably withhold its consent to any
consent requested of the Owner Trustee or the Indenture Trustee, as the case may
be, under the terms of the Operative Agreements that by its terms is not to be
unreasonably withheld by the Owner Trustee or the Indenture Trustee.

     Section 10.2  Refinancing. So long as no Lease Default or Lease Event of
Default shall be in existence (on the date of request or at any time through and
including the Refunding Date, as defined below), the Lessee shall have the right
to request the Owner Participant and the Owner Trustee to effect an optional
prepayment of all, and not less than all, of the Equipment Notes pursuant to
Section 2.10(d) of the Indenture as part of a refunding or refinancing
operation. As soon as practicable after receipt of such request, the Owner
Participant and the Lessee will enter into an agreement, in form and substance
reasonably satisfactory to the parties thereto, as to the terms of such
refunding or refinancing as follows:

     (a) the Lessee, the Owner Participant, the Indenture Trustee, the Owner
Trustee, and any other appropriate parties will enter into a financing or loan
agreement (which may involve an underwriting agreement in connection with a
public offering), in form and substance reasonably satisfactory to the parties
thereto, providing for (i) the issuance and sale by the Owner Trustee or such
other party as may be appropriate on the date specified in such agreement (for
the

                                       48
<PAGE>

purposes of this Section 10.2, the "Refunding Date") of debt securities in an
aggregate principal amount (in the lawful currency of the United States) equal
to the principal amount of the Equipment Notes outstanding on the Refunding
Date, having the same maturity date as said Equipment Notes and having a
weighted average life which is not less than or greater than the Remaining
Weighted Average Life of said Equipment Notes by more than three months, (ii)
the application of the proceeds of the sale of such debt securities to the
prepayment of all such Equipment Notes on the Refunding Date, and (iii) payment
by Lessee to the Person or Persons entitled thereto of all other amounts, in
respect of accrued interest, any Make-Whole Amount or other premium, if any,
payable on such Refunding Date;

     (b)  the Lessee and the Owner Trustee will amend the Lease in a manner such
that (i) if the Refunding Date is not a Rent Payment Date and the accrued and
unpaid interest on the Equipment Notes is not otherwise paid pursuant to Section
10.2(a), the Lessee shall on the Refunding Date prepay that portion of the next
succeeding installment of Basic Rent as shall equal the aggregate interest
accrued on the Equipment Notes outstanding to the Refunding Date, (ii) Basic
Rent payable in respect of the period from and after the Refunding Date shall be
recalculated to preserve the Net Economic Return which the Owner Participant
would have realized had such refunding not occurred, provided that the net
present value of Basic Rent shall be minimized to the extent consistent
therewith, and (iii) amounts payable in respect of Stipulated Loss Value, Early
Purchase Price, Basic Term Purchase Price and Termination Value from and after
the Refunding Date shall be appropriately recalculated to preserve the Net
Economic Return which the Owner Participant would have realized had such
refunding not occurred (it being agreed that any recalculations pursuant to
subclauses (ii) and (iii) of this clause (b) shall be performed in accordance
with the requirements of Section 2.6 hereof);

     (c)  the Owner Trustee will enter into an agreement to provide for the
securing thereunder of the debt securities issued by the Owner Trustee pursuant
to clause (a) of this Section 10.2 in like manner as the Equipment Notes and/or
will enter into such amendments and supplements to the Indenture as may be
necessary to effect such refunding or refinancing, which agreements, amendments
and/or supplements shall be reasonably satisfactory in form and substance to the
Owner Participant; provided that, no such agreement or amendment shall provide
for any increase in the security for the new debt securities; and provided
further that, notwithstanding the foregoing (but subject to the provisions of
clauses (a) and (b) above), the Lessee reserves the right to set the economic
terms and other terms not customarily negotiated between an owner participant
and a lender of the refunding or refinancing transaction to be so offered to the
extent that they are passed through to the Lessee in, or define rights or
obligations of the Lessee under, the Operative Agreements; provided, further,
that no such amendment or supplement will increase the obligations or impair the
rights of the Owner Participant under the Operative Agreements without the
consent of the Owner Participant;

     (d)  in the case of a refunding or refinancing involving a public offering
of debt securities, neither the Owner Trustee nor the Owner Participant shall be
an "issuer" for securities law purposes or an "obligor" within the meaning of
the Trust Indenture Act of 1939, as amended, the offering materials (including
any registration statement) for the refunding or refinancing transaction shall
be reasonably satisfactory to the Owner Participant and the Lessee shall provide
satisfactory indemnity to the Owner Trustee and Owner Participant with respect
thereto;

                                       49
<PAGE>

     (e)  unless otherwise agreed by the Owner Participant, the Lessee shall pay
to the Owner Trustee as Supplemental Rent an amount equal to the Make-Whole
Amount or other premium, if any, payable in respect of Equipment Notes
outstanding on the Refunding Date, and all reasonable fees, costs, expenses of
such refunding or refinancing and of the parties hereto incurred in connection
with such refunding or refinancing (including all reasonable out-of-pocket legal
fees and expenses);

     (f)  the Lessee shall give the Indenture Trustee not less than 25 days
prior written notice of the Refunding Date;

     (g)  the Owner Participant, the Owner Trustee, the Indenture Trustee and
the Pass Through Trustee shall have received (i) such opinions of counsel as
they may reasonably request concerning compliance with the Securities Act of
1933, as amended, and any other applicable law relating to the sale of
securities and (ii) such other opinions of counsel and such certificates and
other documents, each in form and substance satisfactory to them, as they may
reasonably request in connection with compliance with the terms and conditions
of this Section 10.2; and

     (h)  all necessary authorizations, approvals and consents shall have been
obtained; provided, however, that the Lessee will, to the extent then known,
promptly provide to the Owner Participant, the Owner Trustee, the Indenture
Trustee and the Pass Through Trustee substantially final terms and conditions of
any such refunding or refinancing within 30 days prior to the execution and
delivery of the documents contemplated hereunder in connection therewith; and
provided, further, that (v) no refunding or refinancing of the Equipment Notes
will be permitted unless within 20 days after receipt by the Owner Participant
of a request from the Lessee to effect a refunding or refinancing pursuant to
this Section 10.2 and of information regarding the terms of such refunding or
refinancing necessary to render the opinion referred to below, the Lessee has
provided the Owner Participant with (a) a tax opinion from Vedder, Price,
Kaufman & Kammholz or other tax counsel reasonably acceptable to the Owner
Participant to the effect that the Owner Participant would have a reasonable
basis within the meaning of Section 6662(d)(2)(B)(ii) of the Code not to report
any adverse federal income tax consequences as a result of such refunding or
refinancing and (b) an agreement to indemnify the Owner Participant against any
adverse tax consequence suffered as a result of such refinancing or refunding;
alternatively, in the event such reasonable basis tax opinion cannot be provided
and the Lessee wishes to effect such refunding or refinancing, the Lessee will,
at such time as the Lessee receives written notice from the Owner Participant
that the Owner Participant has filed any income tax return wherein such adverse
income tax consequences are recognized, make an indemnity payment to the Owner
Participant in the incremental amount of such adverse tax consequence (on an
After-Tax Basis) attributable to such refunding or refinancing; (w) the Lessee
shall pay to or reimburse the Participants, the Owner Trustee and the Indenture
Trustee for all costs and expenses (including reasonable attorneys' and
accountants' fees) paid or incurred by them in connection with such refunding or
refinancing; (x) no refunding or refinancing of the Equipment Notes will be
permitted if it shall cause the Owner Participant to account for the transaction
contemplated hereby as other than a "leveraged lease" under the Financial
Accounting Standards Board ("FASB") Statement No. 13, as amended (including any
amendment effected by means of the adoption by FASB of a new statement in lieu
of FASB Statement No. 13); and (y) in no event, in connection with or after
giving effect to such

                                      50

refunding or refinancing shall the Owner Participant be exposed to any
unindemnified risk or liability (including tax risk) to which it is not exposed
prior to such refunding or refinancing.

     Section 10.3  Amendments and Waivers. Except as otherwise provided in the
Indenture, no term, covenant, agreement or condition of this Agreement may be

particular instance, retroactively or prospectively) except by an instrument or
instruments in writing executed by each party against which enforcement of the
termination, amendment or waiver is sought.

     Section 10.13  Limitations of Liability.
                    ------------------------

     (a)  Liabilities of Participants. Neither the Indenture Trustee, the Owner
Trustee nor any Participant shall have any obligation or duty to the Lessee, to
any other Participant or to others with respect to the transactions contemplated
hereby, except those obligations or duties of such Participant expressly set
forth in this Agreement and the other Operative Agreements, and neither the
Indenture Trustee nor any Participant shall be liable for performance by any
other party hereto of such other party, obligations or duties hereunder. Without
limitation of the generality of the foregoing, under no circumstances whatsoever
shall the Indenture Trustee or any Participant be liable to the Lessee for any
action or inaction on the part of the Owner Trustee in connection with the
transactions contemplated herein, whether or not such action or inaction is
caused by willful misconduct or gross negligence of the Owner Trustee unless
such action or inaction is at the direction of the Indenture Trustee or any
Participant, as the case may be, and such direction is expressly permitted
hereby.

     (b)  No Recourse to the Owner Trustee. It is expressly understood and
agreed by and between the Owner Trustee, the Lessee, the Owner Participant, the
Indenture Trustee, and the Loan Participant, and their respective successors and
permitted assigns that, subject to the proviso contained in this Section
10.13(b), all representations, warranties and undertakings of the Owner Trustee
hereunder shall be binding upon the Owner Trustee, only in its capacity as Owner
Trustee under the Trust Agreement, and (except as expressly provided herein) the
Trust Company shall not be liable in its individual capacity for any breach
thereof, except for its gross negligence or willful misconduct, or for breach of
its covenants, representations and warranties contained herein, except to the
extent covenanted or made in its individual capacity; provided, however, that
nothing in this Section 10.13(b) shall be construed to limit in scope or
substance those representations and warranties of the Trust Company made
expressly in its individual capacity set forth herein. The term "Owner Trustee"
as used in this Agreement shall include any successor trustee under the Trust
Agreement, or the Owner Participant if the trust created thereby is revoked.

     Section 10.14  Maintenance of Non-Recourse Debt. The parties hereto agree
that if the Owner Trustee becomes a debtor subject to the reorganization
provisions of the Bankruptcy Code, 11 U.S.C. (S)101 et seq. (the "Bankruptcy
Code") or any successor provision, the parties hereto will make an election
under 1111(b)(1)(A)(i) of the Bankruptcy Code. If (a) the Owner Trustee becomes
a debtor subject to the reorganization provisions of the Bankruptcy Code or any
successor provision, (b) pursuant to such reorganization provisions the Owner
Trustee is required, by reason of the Owner Trustee being held to have recourse
liability to the Pass Through Trustee or the Indenture Trustee, directly or
indirectly, to make payment on account of any amount payable under the Equipment
Notes or any of the other Operative Agreements and (c) the Pass Through Trustee
and/or the Indenture Trustee actually receives any Excess Amount (as hereinafter
defined) which reflects any payment by the Owner Trustee on account of (b)
above, then the Pass Through Trustee and/or the Indenture Trustee, as the case
may be, shall promptly refund to the Owner Trustee such Excess Amount. For
purposes of this Section 10.14 "Excess Amount" means the amount by which such
payment exceeds the amount which would have been received by the Pass Through
Trustee or the Indenture Trustee if the Owner Trustee had not become subject to
the recourse liability referred to in (b) above.

     Section 10.15  Ownership of and Rights in Units. The sale of the Units
contemplated hereby is intended for all purposes to be a true sale of all of the
Lessee's right, title and interest in and to the Units to the Owner Trustee,
which shall be the legal owner thereof. Upon consummation of the sale and
leaseback transactions contemplated hereby, the Lessee's interest in the Units
is intended to be that of a lessee only. It is intended that for federal and
state income tax purposes the Owner Participant will be the owner of the Units.
The rights of the Indenture Trustee in and to the Units pursuant to the
Indenture is intended to be that of a secured party holding a security interest,
subject to the Lease and the rights of the Lessee thereunder. No holder of an
Equipment Note is intended to have any right, title or interest in or to the
Units except as a beneficiary of the security interest granted by the Owner
Trustee to the Indenture Trustee pursuant to the Indenture in trust for the
equal and ratable benefit of the holders from time to time of the Equipment
Notes.

     Section 10.16  Deferred Payment for Early Purchase Option.  If Lessee
elects to exercise an early purchase option pursuant to Section 22.1(b) of the
Lease with respect to Units in a Basic Group, Lessee may, at its option, either
(x) pay the entire Early Purchase Price  applicable to such Units on the
applicable Early Purchase Date, as provided in Section 22.1(b) of the Lease and
Schedule 6A of this Participation Agreement or (y) pay a portion of such Early
Purchase Price on the applicable Early Purchase Date and the balance in
installments thereafter, on the applicable dates and in the applicable amounts
for such Basic Group as indicated on Schedule 6B, provided that Lessee may not
elect the option set forth in this clause (y) herein unless the principal amount
of the related Equipment Note applicable to such Units together with accrued
interest thereon and any applicable Make-Whole Amount shall have been paid in
respect of such Units pursuant to Section 2.10(c) of the Indenture and all other
sums due owing to Indenture Trustee and Loan Participants under the Operative
Agreements shall have been paid in full on or prior to the Early Purchase Date.
Notwithstanding anything in this Agreement to the contrary, the Lessee shall not
be permitted to exercise any of its rights under Section 9 of this Agreement
with respect to any Units as to which the Lessee has exercised its option set
forth in clause (y) of the first paragraph of this Section 10.16.

     Lessee shall elect its payment option in the applicable notice given
pursuant to Section 22.1(b) of the Lease. If Lessee elects the option specified
in clause (y) of the first paragraph of this Section 10.16, then on the date the
initial installment is paid,

          (i)  the Lease shall be deemed terminated as to such Units and the
     Owner Trustee and the Lessee shall enter into a loan and security agreement
     in respect of the deferred Early Purchase Price in form and substance
     reasonably satisfactory to the Owner Trustee and which incorporates therein
     events of default substantially similar to those set forth in the Lease and
     covenants and terms substantially similar to those set forth in the Lease,
     and the Lessee shall deliver a legal opinion in form and substance
     reasonably satisfactory to the Owner Trustee as to the creation and
     perfection of the Owner Trustee's security interest in such Units.

          (ii)  Basic Rent in respect of such Units shall cease to accrue,

          (iii)  the Owner Trustee will convey all of its right, title and
     interest and to such Units to Lessee by delivery of a bill of sale without
     recourse or warranty except as to the  absence of Lessor's Liens, subject,
     however, to the security interest of the Owner Trustee then being retained
     under the agreement referred to in clause (y) above, and

          (iv)  the Lessee shall execute such documents and take all such
     actions as Owner Trustee may reasonably request to perfect such security
     interest.

Upon payment by Lessee of the last installment, the Owner Trustee shall execute
and deliver to Lessee a release of the security interest so retained. all
reasonable costs and expense of the Owner Trustee and the Owner Participant
incurred in connection with the Lessee's election under this Section 10.16,
including, without limitation, the costs and expenses of all filings necessary
and appropriate to perfect the security interest of the Owner Trustee intended
to be established pursuant to this Section 10.16, shall be paid by the Lessee.

     Section 2.6 Calculation of Adjustments to Basic Rent, Stipulated Loss Value
                 ---------------------------------------------------------------
and Termination Value; Confirmation and Verification.
----------------------------------------------------

     (a) Calculation of Adjustments.  In the event that (A) the Closing Date is
other than April 13, 2000 or (B) the Transaction Costs paid by the Owner
Participant pursuant to Section 2.5 prior to the first Rent Payment Date are
less or more than $771,479.47 for the Equipment or (C) a refinancing
contemplated by Section 10.2 occurs, (D) any change in the Code which is enacted
and effective and/or any change in the income tax regulations which is
promulgated, adopted and effective prior to the Closing Date (provided the Owner
Participant or the Lessee shall have given notice of such change to the other
party prior to such Closing Date), which change alters or eliminates the tax
assumptions upon which the calculation of Basic Rent, Stipulated Loss Values,
Termination Values, Early Purchase Price and Basic Term Purchase Price were
based, or (E) the Equipment Cost or the composition of the Units is different
than as described on Schedule 1 hereto, or (F) the Debt Rate on, and
                     ----------
amortization of the Equipment Notes is different than the assumptions upon which
the calculations of the Basic Rent was based, then, in each such case, the Owner
Participant shall recalculate the payments or amounts, as the case may be, of
Basic Rent, Stipulated Loss Values, Termination Values, Early Purchase Price and
Basic Term Purchase Price, (i) to preserve the Net Economic Return that the
Owner Participant would have realized in the absence of the changes referred to
in Sections (A) through (F) of this Section 2.6(a) and (ii) to minimize to the
greatest extent possible, consistent with the foregoing clause (i), the present
value (discounted semiannually at an interest rate per annum equal to the Debt
Rate) of the payments of Basic Rent.  Any such recalculation performed due to
the occurrence of an event described in clause (A), (B), (D), (E), and (F) above
shall be made prior to the first Rent Payment Date.  In performing any such
recalculation and in determining the Owner Participant's Net Economic Return,
the Owner Participant shall utilize the same methods and assumptions originally
used in making the computations of Basic Rent, Stipulated Loss Values,
Termination Values, Early Purchase Price and Basic Term Purchase Price with
respect to the Basic Term initially set forth in Schedules 3, 4, 6 and 7 to this
                                                 -----------------------
Participation Agreement (other than those assumptions changed as a result of any
of the events described in clauses (A) through (F) of the preceding sentence
necessitating such recalculation; it being

                                       7
<PAGE>

agreed that such recalculation shall reflect solely any changes of assumptions
or facts resulting directly from the event or events necessitating such
recalculation). Such adjustments shall comply (to the extent the original
structure complied but allowing variations to reflect the event giving rise to
the adjustment) with Section 467 of the Code and any regulations thereunder so
as not to cause the Lease to be a "disqualified leaseback or long-term
agreement" within the meaning of Section 467 of the Code and any regulation
thereunder, and the requirements of Sections 4.02(5), 4.07(1) and (2) and
4.08(1) of Revenue Procedure 75-28, as amended, calculated, except in the case
of a refinancing pursuant to Section 10.2, without taking into account any
change after the Closing Date in or to Section 467 of the Code (and any
regulations thereunder) and such requirements of Revenue Procedure 75-28.

     (b) Confirmation and Verification.  Upon completion of any recalculation
described above in this Section 2.6, a duly authorized officer of the Owner
Participant shall provide a certificate to the Lessee either (x) stating that
the payments of Basic Rent, Stipulated Loss Values, Termination Values, Early
Purchase Price and Basic Term Purchase Price with respect to the Basic Term as
are then set forth in Schedules 3, 4, 6 and 7 of this Participation Agreement do
                      -----------------------
not require change, or (y) setting forth such adjustments to the payments of
Basic Rent, Stipulated Loss Values, Termination Values, Early Purchase Price or
Basic Term Purchase Price with respect to the Basic Term as have been calculated
by the Owner Participant in accordance with Section 2.6(a) above.  Such
certificate shall describe in reasonable detail the basis for any such
adjustments, and any such adjustment and corresponding adjustments to the
Stipulated Loss Values, Termination Values, Early Purchase Price and Basic Term
Purchase Price will be computed on a basis consistent with that used by the
Owner Participant in the original calculation of Basic Rent.  Any such
adjustment shall be deemed approved upon notice of such approval by the Lessee
to the Owner Participant or on the thirty-first (31st) day following delivery of
such certificate by the Owner Participant to the Lessee unless the Lessee, prior
to such day, requests verification pursuant to the following sentence, and shall
become effective as of the earlier of (i) the first Rent Payment Date and (ii)
the date the Lessee approves or has been deemed to have approved such adjustment
(except that any adjustment to Stipulated Loss Value shall be effective as of
the Closing Date).  If the Lessee shall so request, the recalculation of any
such adjustments described in this Section 2.6 shall be verified on a
confidential basis by a nationally recognized firm of independent accountants
selected by the Owner Participant and reasonably acceptable to the Lessee and
any such recalculation of such adjustment as so verified shall be binding on the
Lessee and the Owner Participant.  Such accounting firm shall be requested to
make its determination within 30 days.  The Owner Participant shall provide to a
representative of such accounting firm, on a confidential basis, such
information as it may reasonably require, including the original assumptions
used by the Owner Participant and the methods used by the Owner Participant in
the original calculation of, and any recalculation of, Basic Rent, Stipulated
Loss Values, Termination Values, Early Purchase Price and Basic Term Purchase
Price and such other information as is necessary to determine whether the
computation is accurate and in conformity with the provisions of this Agreement,
provided that in no event shall the Owner Participant have any obligation to
--------
provide the Lessee with any such information; and provided, further, that the
                                                  --------  -------
Owner Participant shall have no obligation to disclose to the Lessee, such
accounting firm or any other Person, or to permit the Lessee, such accounting
firm or any other Person, to examine any federal, state or local income tax
returns of the Owner Participant, or books or accounting records related
thereto, for any taxable year.  Subject to the immediately following sentence,
the costs of such verification shall be borne by the Lessee.  If such accounting
firm's verification shall result

                                       8
<PAGE>

in a decrease in the net present value (expressed as a percentage of Total
Equipment Cost) of the Basic Rent (discounted semiannually at a rate per annum
equal to the Debt Rate) under this Lease calculated as of the Closing Date, as
compared to the net present value of Basic Rent proposed by the Owner
Participant, by more than the greater of (a) 10 basis points or (b) 10% of the
proposed adjustment, then the Owner Participant agrees to reimburse the Lessee
for any amounts paid for such verification. Any revised adjustment resulting
from such verification shall become effective on the next Rent Payment Date
after such verification has been concluded (except that any adjustment to
Stipulated Loss Value shall be effective as of the Closing Date), and shall take
into account any underpayment or overpayment, together with interest thereon at
the Debt Rate, resulting from an earlier effectiveness of the original
adjustment.

     (c) Compliance.  Notwithstanding the foregoing, any adjustment made to the
payments of Basic Rent, Stipulated Loss Values, Termination Values or Early
Purchase Price with respect to the Basic Term, pursuant to the foregoing, shall
comply with the following requirements:  (i) each installment of Basic Rent, as
so adjusted, under any circumstances and in any event, will be in an amount at
least sufficient for the Owner Trustee to pay in full as of the due date of such
installment any payment of principal of and interest on the Equipment Notes
required to be paid on the due date of such installment of Basic Rent, and (ii)
Stipulated Loss Value, Termination Value and Early Purchase Price, as so
adjusted, under any circumstances and in any event, will be an amount which,
together with any other amounts required to be paid by the Lessee under the
Lease in connection with an Event of Loss or a termination of the Lease, as the
case may be, will be at least sufficient to pay in full, as of the date of
payment thereof, the aggregate unpaid principal of, any Make-Whole Amount and
all unpaid interest on the Equipment Notes, accrued to the date on which
Stipulated Loss Value, Termination Value or Early Purchase Price, as the case
may be, is paid in accordance with the terms of the Lease.

     (d) Invoices.  All invoices in respect of Transaction Costs to the extent
not delivered on the Closing Date shall be directed to the Owner Participant at
the address set forth in Section 10.4, with a copy to the Lessee.

     Section 2.7 Postponement of Closing Date.
                 ----------------------------

     (a) The scheduled Closing Date may be postponed from time to time with
respect to all of the Units for any reason (but to no later than April 28, 2000)
if the Lessee gives the Owner Participant, the Indenture Trustee, the Pass
Through Trustee and the Owner Trustee telex, telegraphic, facsimile or
telephonic (confirmed in writing) notice of the postponement and notice of the
date to which such Closing Date has been postponed, the notice of postponement
to be received by each party no later than 5:30 p.m., New York City time, on the
originally scheduled Closing Date, and the term "Closing Date" as used in this
Agreement shall mean the postponed "Closing Date".

     (b) In the event of any postponement of the originally scheduled Closing
Date pursuant to this Section 2.7 (the originally scheduled Closing Date being
referred to as the "Scheduled Closing Date" for the purposes of this Section
2.7):  (i) the Lessee will reimburse the Owner Participant for the loss of the
use of its funds with respect to each such Unit occasioned by such postponement
or failure to deliver or accept (unless such failure to accept is caused by a
default by the Owner Participant hereunder or by the Owner Trustee (acting
pursuant to

                                       9
<PAGE>

instructions from the Owner Participant) under the Trust Agreement, the Lease or
the Indenture) by paying to the Owner Participant on demand interest at the Debt
Rate, for the period from and including the Scheduled Closing Date to but
excluding the earlier of the date upon which such funds are returned to the
Owner Participant (unless such funds are returned after 1:00 p.m., New York City
time, in which case such date of return shall be included) or the actual Closing
Date; provided that the Lessee shall in any event pay to the Owner Participant
      --------
at least one day's interest at the Debt Rate on the amount of such funds, unless
the Owner Participant shall have received, prior to 12:00 noon, New York City
time, on the Business Day preceding the Scheduled Closing Date, a notice of
postponement of the Scheduled Closing Date pursuant to Section 2.7(a), and (ii)
the Indenture Trustee will return not later than 10:00 a.m., New York City time,
on the first Business Day following the Scheduled Closing Date, any funds which
it shall have received from the Owner Participant as its Commitment for such
Units, absent joint instructions from the Lessee and the Owner Participant to
retain such funds until the specified date of postponement established under
Section 2.7(a).

     (c) The Indenture Trustee agrees that, in the event it has received
telephonic notice (to be confirmed promptly in writing) from the Lessee on the
Scheduled Closing Date that such Scheduled Closing Date is to be postponed, it
will if instructed in the aforementioned notice from the Lessee (which notice
shall specify the securities to be purchased) use reasonable best efforts to
invest, at the risk of the Lessee (except as provided below with respect to the
Indenture Trustee's gross negligence or willful misconduct), the funds received
by it from the Owner Participant with respect to its Commitment in Specified
Investments in accordance with the Lessee's instructions.  Any such Specified
Investments purchased by the Indenture Trustee upon instructions from the Lessee
shall be held in trust by the Indenture Trustee (but not as part of the
Indenture Estate under the Indenture) for the benefit of the Owner Participant
whose funds are invested in Specified Investments upon instructions from the
Lessee and any net profits on the investment of such funds (including interest),
if any, shall be for the account of and shall on the Closing Date, or on the
date such funds are returned to the Owner Participant, be paid over to, the
Lessee.  The Lessee shall pay to the Indenture Trustee on the Closing Date (if
such Unit or Units are delivered and accepted pursuant hereto) the amount of any
net loss on the investment of such funds invested at the instruction of the
Lessee.  If the funds furnished by the Owner Participant with respect to such
Unit or Units are required to be returned to the Owner Participant, the Lessee
shall, on the date on which such funds are so required to be returned, reimburse
the Indenture Trustee, for the benefit of the Owner Participant, for any net
losses incurred on such investments.  The Indenture Trustee shall not be liable
for failure to invest such funds or for any losses incurred on such investments
except for its own willful misconduct or gross negligence.  In order to obtain
funds for the payment of Equipment Cost for such Unit or Units or to return
funds furnished by the Owner Participant to the Indenture Trustee for the
benefit of the Owner Participant with respect to such Unit or Units, the
Indenture Trustee is authorized to sell any Specified Investments purchased as
aforesaid with the funds received by it from the Owner Participant in connection
with such Unit or Units.

     (d) Notwithstanding the provisions of Section 2.7(a), the Owner Participant
shall not be under any obligation to make its Commitment available beyond 11:00
a.m., New York City time, on April 28, 2000.

delivered on the Closing Date;

     (g) both its chief executive office, and the place where its records

     Section 3.2 Representations and Warranties of the Lessee.  The Lessee
                 --------------------------------------------
represents and warrants to the Trustees and the Owner Participant that, as of
the date hereof:

     (a) the Lessee is a corporation duly organized, validly existing, and in
good standing under the laws of the State of New York, is duly licensed or
qualified and in good standing in each jurisdiction in which the failure to so
qualify would have a material adverse effect on its ability to carry on its

     (b) the Lessee Agreements have been duly authorized by all necessary
corporate action (no shareholder approval being required), executed and
delivered (or in the case of the Lease Supplements in respect of the Units
delivered on the Closing Date will on the Closing Date have been duly executed
and delivered) by the Lessee, and constitute (or in the case of the Lease
Supplement in respect of the Units delivered on the Closing Date will on the

enforceable against the Lessee in accordance with their respective terms except
as enforceability may be limited by bankruptcy, insolvency, reorganization,
moratorium or similar laws affecting the rights of creditors generally and by
general principles of equity;

     (c) the execution, delivery and performance by the Lessee of each Lessee
Agreement and compliance by the Lessee with all of the provisions thereof do not
and will not contravene any law or regulation, or any order of any court or
governmental authority or agency applicable to or binding on the Lessee or any
of its properties, or contravene the provisions of, or constitute a default by
the Lessee under, or result in the creation of any Lien (except for Permitted
Liens) upon the property of the Lessee under its certificate of incorporation or
by-laws or any indenture,

                                       13
<PAGE>

mortgage, contract or other agreement or instrument to which the Lessee is a
party or by which the Lessee or any of its property is bound or affected;

     (d) except for those matters discussed in the financial statements provided
to the Participants under Section 3.2(e), there are no proceedings pending or,
to the knowledge of the Lessee, threatened against the Lessee or any Subsidiary
in any court or before any governmental authority or arbitration board or
tribunal which individually or in the aggregate would, if determined adversely
to it, materially and adversely affect the financial condition or business of
the Lessee and its consolidated Subsidiaries, taken as a whole, or impair the
ability of the Lessee to perform its obligations under the Lessee Agreements or
which questions the validity of any Lessee Agreement or any action taken or to
be taken pursuant thereto.  Neither the Lessee nor any Subsidiary is in default
with respect to any order of any court or governmental authority or arbitration
board or tribunal, the default under which would affect adversely the ability of
the Lessee to perform its obligations under the Lessee Agreements;

     (e) the audited consolidated balance sheets and consolidated statements of
income and retained earnings and cash flows of the Lessee for the fiscal year
ended December 31, 1999 fairly present, in conformity with generally accepted
accounting principles, the consolidated financial position of the Lessee and its
Subsidiaries as of such date and the results of their operations for the period
then ended.  The unaudited consolidated balance sheets and consolidated
statements of income and retained earnings and cash flows of the Lessee and its
Subsidiaries for the twelve-month period ended December 31, 1999 fairly present,
in conformity with generally accepted accounting principles consistently applied
(except for the absence of footnotes in the December 31, 1999 financial
statements), the consolidated financial position of the Lessee and its
Subsidiaries as of such date and the results of their operations for the period
then ended, subject to normal year-end adjustments.  Since December 31, 1999,
there has been no material adverse change in the condition, financial or
otherwise, of the Lessee and its consolidated Subsidiaries, taken as a whole, as
shown on the financial statements of Lessee as of such date;

     (f) no consent, approval or authorization of, or filing, registration or
qualification with, or the giving of notice to, any trustee or any holder of
indebtedness of Lessee or any governmental authority on the part of the Lessee
is required in connection with the execution and delivery by the Lessee of the
Lessee Agreements, other than notices required to be filed with the STB and the
Registrar General of Canada, which STB notice shall have been filed on the
Closing Date and which Canadian notice shall be filed promptly following the
Closing Date;

     (g) the Lease, the Indenture, the Lease Supplements in respect of the Units
delivered on the Closing Date and the Indenture Supplements in respect of the
Units delivered on the Closing Date will on or before the Closing Date be duly
filed with the STB pursuant to 48 U.S.C. (S)11301 and deposited with the
Registrar General of Canada pursuant to Section 105 of the Canada Transportation
Act and such filing with the STB pursuant to 49 U.S.C. (S)11301 will perfect the
Owner Trustee's and the Indenture Trustee's rights in such Operative Agreements
and in the Units, and such deposit with the Registrar General of Canada will
perfect the Owner Trustee's and the Indenture Trustee's rights in such Operative
Agreements and in the Units and no other filing, recording or deposit with, or
giving of notice to any other federal, state, provincial or local government or
agency thereof, or any other action, is necessary in order to

                                       14
<PAGE>

protect the rights of the Owner Trustee and the Indenture Trustee in such
Operative Agreements or in such Units in the United States, any state thereof,
the District of Columbia or to protect the rights of the Owner Trustee and the
Indenture Trustee in such Operative Agreements or in such Units in Canada or any
province thereof;

     (h) the Equipment is covered by the insurance required by Section 12 of the
Lease and all premiums due prior to the Closing Date in respect of such
insurance shall have been paid in full;

     (i) the Lessee has timely filed all United States Federal income tax
returns and all other material tax returns which are required to be filed by it
and has paid all taxes due pursuant to such returns or pursuant to any
assessment made against the Lessee or any of its assets (other than assessments,
the payment of which is being contested in good faith by appropriate proceedings
by the Lessee and none of which are material), and no tax liens have been filed
and no claims are being asserted with respect to any such taxes, fees or other
charges which could reasonably be expected to have a materially adverse effect
on its ability to perform its obligations under the Lessee Agreements.  The
provision for taxes on the books of the Lessee is adequate for all open years,
and for its current fiscal period;

     (j) no Lease Default or Lease Event of Default has occurred and is
continuing and to the knowledge of Lessee, no Event of Loss, or event with which
the giving of notice and/or the passage of time would constitute an Event of
Loss, has occurred;

     (k) the Lessee is not an "investment company" or an "affiliated person" of
an "investment company" within the meaning of the Investment Company Act of
1940;

     (l) the acquisition by the Owner Participant of the Beneficial Interest for
its own account will not constitute a prohibited transaction within the meaning
of Section 4975(c)(1)(A) through (D) of the Code or a "Prohibited Transaction"
under ERISA.  The representation made by the Lessee in the preceding clause is
made in reliance upon and subject to the accuracy of the representation of the
Owner Participant in Section 3.6(h) of this Agreement;

     (m) on the Closing Date, Lessee shall have, and the Bill of Sale to be
delivered on the Closing Date shall convey, to the Owner Trustee all legal and
beneficial title to the Units being delivered on the Closing Date, free and
clear of all Liens (other than Permitted Liens of the type described in clause
(ii) with respect to sublessee, and in clauses (iii), (iv), (vi) and (vii) of
the definition thereof), and such conveyance is not void or voidable under any
applicable law;

     (n) the financial statements referred to in Section 3.2(e) do not, nor does
the Registration Statement relating to the Pass Through Certificates or any
written statement furnished by the Lessee or on behalf of the Lessee in
connection with the negotiation of the Lease or any other Operative Agreement,
contain any untrue statement of a material fact or omit a material fact
necessary to make the statements contained therein or herein not misleading.
There is no fact which the Lessee has not disclosed in writing which materially
affects adversely or, so far as the Lessee can now reasonably foresee, will
materially affect adversely the properties, business, prospects, profits or
condition (financial or otherwise) of the Lessee and its Subsidiaries, taken as
a whole;

                                       15
<PAGE>

     (o) none of the transactions contemplated by the Operative Agreements
(including, without limitation, the use of the proceeds from the sale of the
Equipment Notes) will result in a violation of Section 7 of the Securities
Exchange Act of 1934, as amended, or any regulations issued pursuant thereto,
including, without limitation, Regulations G, T, U and X of the Board of
Governors of the Federal Reserve System, 12 C.F.R., Chapter II.  None of the
proceeds from the sale of the Equipment Notes will be used to purchase or carry
(or refinance any borrowing the proceeds of which were used to purchase or
carry) any "security" within the meaning of the Securities Exchange Act of 1934,
as amended;

     (p) the Lessee is not in violation of any term of any charter instrument,
by-law or in any material respect of any other material agreement or instrument
to which it is a party or by which it may be bound.  The Lessee is in compliance
with all laws, ordinances, governmental rules and regulations to which it is
subject, the failure to comply with which would have a material and adverse

effect as if such successor corporation had been named as the Lessee herein.

     Section 6.9 Lessee's Purchase in Certain Circumstances.  If an Owner
                 ------------------------------------------
Participant or any Affiliate thereof is or acquires, is acquired by, merges or
otherwise consolidates with any company or Affiliate thereof engaged in full
service railcar leasing, whether or not a direct competitor to the Lessee or any
Affiliate thereof, or any Person that has a material interest (whether held
directly or indirectly) in an enterprise that engages in a business that is
competitive with the Lessee's full service railcar leasing business, the Lessee
may, no later than one year after a Responsible Officer of the Lessee has actual
knowledge of such event, request that such Owner Participant transfer its
Beneficial Interest pursuant to Section 6.1.  If such Owner Participant has not
transferred its Beneficial Interest within 180 days of such request, the Lessee
may, on a Determination Date which is designated by the Lessee by written notice
to the Owner Trustee and the Indenture Trustee not less than 25 days prior to
such Determination Date, purchase a number of the Units of Equipment equal to
the percentage of the Equipment that the portion of the Beneficial Interest held
by such Owner Participant bears to 100% of the Beneficial Interest for a
purchase price equal to the Termination Value for such Units calculated as of
such Determination Date, together with all other amounts due and owing by the
Lessee under the Operative Agreements with respect to such Units, including,
without limitation, all accrued and unpaid Basic Rent therefor as of such
Determination Date (exclusive of any in advance Basic Rent due on such date) and
any Make-Whole Amount then payable on the Equipment Notes pursuant to Section
2.10(c) of the Indenture with respect to such Units; provided, that an
                                                     --------
institutional investor which is a passive investor in the financing of equipment
or facilities used in full service railcar leasing shall not, solely by reason
of such investment, be deemed to be engaged in such businesses; provided,
                                                                --------
further, that none of any Owner Participant or Affiliate thereof shall be deemed
-------
to (i) be engaged in full service railcar leasing or (ii) hold (directly or
indirectly) any material interest in any business that is competitive with the
Lessee's full service railcar leasing business, solely by reason of any sale,
lease or other disposition (or any actions in furtherance of any of the
foregoing), of any of such Person's interest in any equipment or facilities
directly or indirectly owned, leased or otherwise controlled pursuant to any
such Person's passive investment in the financing of any such equipment or
facilities used in full service railcar leasing.  In the event that such Owner
Participant hereinabove referred to holds less than 100% of the Beneficial
Interest, the determination as to which Units are to be purchased under this
Section 6.9 shall be made on a random or other basis (in each case reasonably
acceptable to the Lessor) without discrimination based on maintenance status,
operating condition of the Units in question or otherwise and the notice
hereinabove referred to shall describe such manner in which the Lessee proposes
to determine which Units are to be purchased hereunder.

     If the Lessee elects to exercise the purchase option provided for in this
Section 6.9, the Lessee shall, as the purchase price therefor, in the sole
discretion of the Lessee, either (i) pay the Termination Value, as specified in
the paragraph above, with respect to such Units, together with

                                       34
<PAGE>

all other amounts due and owing by the Lessee under the Operative Agreements, or
(ii) pay the difference between the Termination Value and the portion of the
outstanding principal amount of the Equipment Notes which relates to such Units
as of the Determination Date specified by the Lessee in the first sentence of
this Section 6.9 and assume on a full resource basis, and indemnify the Lessor
against, all of the Owner Trustee's obligations under the Indenture in respect
of such portion of the indebtedness evidenced by such Equipment Notes; provided,
                                                                       --------
that, following such assumption, the purchased Units shall remain subject to the
lien of a separate indenture similar to the Indenture pursuant to Section 3.06
of the Indenture. The Lessee will make the payments required by foregoing clause
(i) or assume such portion of the indebtedness evidenced by the Equipment Notes
which relates to such Units as provided in foregoing clause (ii) on the
Determination Date designated in the first sentence of Section 6.9 in
immediately available funds against delivery of a bill of sale transferring and
assigning to the Lessee all right, title and interest of the Lessor in and to
the Units on an "as-is" "where-is" basis and containing a warranty against
Lessor's Liens. In such event, the costs of preparing the bill of sale and all
other documentation relating to such purchase and the costs of any necessary
filings related thereto will be borne by the Lessee. If the Lessee shall fail to
fulfill its obligations under this second paragraph of Section 6.9, all of the
Lessee's obligations under the Lease and the Operative Agreements, including,
without limitation, the Lessee's obligation to pay installments of Rent, with
respect to the Units in question shall continue.

     Section 6.10 Owner Participant an Affiliate of Lessee. If at any time the
                  ----------------------------------------
original or any successor Owner Participant shall be an Affiliate of the Lessee,
such Owner Participant and the Lessee agree that notwithstanding Section 9.05 of
the Indenture they will not vote its Beneficial Interest to modify, amend or
supplement any provision of the Lease or this Agreement or give, or permit the
Owner Trustee to give, any consent, waiver, authorization or approval thereunder
if any such action would adversely affect in a material manner the Indenture
Trustee or any holder of an Equipment Note unless such action shall have been
consented to by a Majority in Interest.

     Section 6.11 Corporate Existence; Place of Business. The Lessee shall at
                  --------------------------------------
all times maintain its corporate existence except as permitted by Section 6.8;
and it shall do or cause to be done all things necessary to preserve and keep in
full force and effect its corporate rights, powers, privileges and franchises
except for any corporate right, power, privilege or franchise that it in good
faith determines is no longer necessary or desirable in the conduct of its
business.

     Section 6.12 No Impairment of Warranties. From and after the Closing Date
                  ---------------------------
and throughout the Lease Term, the Lessee shall not take any action (or fail to
take any action) if the result of such action (or failure to act) would abrogate
or invalidate or otherwise materially adversely affect the validity of any
warranties applicable to the Units which would otherwise be available with
respect to the Units.

SECTION 7. LESSEE'S INDEMNITIES.

     Section 7.1  General Tax Indemnity.
                  ---------------------

     (a) Tax Indemnitee Defined.  For purposes of this Section 7.1, "Tax
Indemnitee" means the Owner Participant, its Affiliates, the Owner Trustee, the
Trust Company, the Indenture Trustee both in its individual capacity and as
trustee, the Pass Through Trustee both in its

                                       35
<PAGE>

individual capacity and as trustee, each of their respective successors or
assigns permitted under the terms of the Operative Agreements, any officer,
director, employee or agent of any of the foregoing, the Trust Estate and the
Indenture Estate.

     (b) Taxes Indemnified.  All payments by the Lessee to any Tax Indemnitee in
connection with the transactions contemplated by the Operative Agreements shall
be free of withholdings of any nature whatsoever (and at the time that the
Lessee is required to make any payment upon which any withholding is required
the Lessee shall pay an additional amount such that the net amount actually
received will, after such withholding and on an After-Tax Basis, equal the full
amount of the payment then due) and shall be free of expense to each Tax
Indemnitee for collection or other charges, provided, however, that no such
                                            --------  -------
additional amounts shall be paid by the Lessee and the Lessee assumes no
responsibility regarding any withholdings (i) imposed by reason of any transfer
of the Equipment or any interest in the Operative Agreements by the Lessor or
the Owner Participant, (ii) imposed solely by reason of a nexus between the
affected Tax Indemnitee and the jurisdiction imposing such withholding which
nexus is unrelated to the transactions contemplated by the Operative Agreements,
or (iii) imposed by the United States by reason of the status of the Tax
Indemnitee as a foreign corporation or nonresident individual, provided,
                                                               --------
further, however, that, notwithstanding the exclusions contained in the
-------  -------
preceding clauses (i) - (iii), Lessee agrees to pay an additional amount of Rent
such that the net amount actually received by the Indenture Trustee, after all
such withholding, is sufficient to pay the related amounts due on the Equipment
Notes and the Lessee shall be entitled to recover such amounts under the next
succeeding sentence.  If, for any reason, the Lessee is required to make any
payment to a taxing authority with respect to, or as a result of, any
withholding tax imposed on any Tax Indemnitee in respect of the transactions
contemplated by the Operative Agreements which withholding tax is not the
responsibility of the Lessee under this Section 7.1 then such Tax Indemnitee
shall pay to the Lessee within 30 days of a demand an amount which equals the
amount paid by the Lessee with respect to, or as a result of, such withholding
tax, plus interest computed at such Tax Indemnitee's cost of funds rate during
the period commencing on the date the Lessee shall have paid an additional
amount pursuant to the first sentence of this paragraph and ending on the date
the Lessee actually receives such payment.

     Subject to the exclusions stated in subsection (c) below, the Lessee agrees
to indemnify and hold harmless each Tax Indemnitee, on an After-Tax Basis,
taking into account the income tax consequences to the Tax Indemnitee of the
accrual or receipt of an indemnity payment, against all fees (including, without
limitation, license, documentation or other fees and registration fees), taxes
(including, without limitation, income, gross receipts, franchise, sales, use,
rental, turnover, business, occupation, excise, value-added, tangible and
intangible personal property and stamp taxes), levies, assessments, imposts,
duties, charges or withholdings of any nature, together with any and all
penalties, additions to tax, fines or interest thereon ("Taxes") imposed upon
any Tax Indemnitee, the Lessee or any Person in possession of the Equipment or
all or any part of the Equipment by any federal, state or local government,
political subdivision, or taxing authority in the United States or its
possessions, by any government or taxing authority of or in a foreign country or
by any international authority, upon, with respect to or in connection with:

         (i) the Equipment or any part of any of the Equipment or interest
     therein;

                                       36
<PAGE>

          (ii) acquisition, financing, ownership, leasing, possession, purchase,
     acceptance, rejection, condition, registration, return, use, storage,
     operation, return, transfer of title, maintenance, repair, improvement,
     replacement, substitution, delivery, redelivery, non-delivery, transport,
     preparation, assembly, insurance, construction, manufacture, insuring,
     modification, transfer, control, occupancy, servicing, mortgaging,
     location, refinancing, disposition, subleasing, repossession, abandonment,
     sale or other application or disposition of or with respect to the
     Equipment or any part of any of the Equipment or interest therein;

          (iii) the rental payments, receipts on earnings arising from any Unit
     of Equipment or payable pursuant to the Lease;

          (iv)  the Equipment Notes, their issuance, acquisition, transfer or
     refinancing or (as between the Lessee and any Tax Indemnitee other than the
     Indenture Estate) the payment of principal, interest or premium or other
     amounts with respect thereto; and

          (v)   the Operative Agreements or otherwise in connection with the
     transactions contemplated thereby.

     (c)  Taxes Excluded.  The indemnity provided for in paragraph (b) above
shall not extend to any of the following:

          (i)   In the case of the Owner Participant, the Owner Trustee or the
     Trust Estate, Income Taxes (as defined in Section 7.1(l), below) imposed by
     (A) the United States federal government (provided that this subclause (A)
     shall not be construed as preventing Lessee from recouping any such federal
     Income Taxes imposed by way of deduction or withholding from the Indenture
     Trustee, the Pass Through Trustee or any Certificateholder or as giving to
     the Indenture Trustee a right to indemnification by the Lessee for Taxes
     payable pursuant to Section 5.09 of the Indenture), (B) any state or local
     tax jurisdiction in the United States (unless such Tax Indemnitee would not
     have been subject to tax in such jurisdiction but for this transaction
     (including the operation or presence of any Unit (or part thereof) and
     other leasing transactions between the Lessee (or its Affiliates) and the
     Owner Participant (or its Affiliates) or the Lessee making payment from or
     performing other actions in such jurisdiction)), provided, that for
                                                      --------
     purposes of determining whether any Tax Indemnitee would not have been
     subject to tax in such jurisdiction but for this transaction, the
     determination of (y) whether any Tax Indemnitee is treated as being
     incorporated or having its principal place of business in any state or
     local tax jurisdiction for purposes of this clause (B), or (z) whether any
     such Tax Indemnitee is deemed to be subject to tax in any state or local
     tax jurisdiction (and would have been subject to such tax without regard to
     this transaction) for purposes of this clause (B), shall be made by
     treating each corporation which is a Tax Indemnitee on a stand-alone basis
     and without regard to any Affiliates, related Tax Indemnitee or other
     entities, except to the extent that such Tax Indemnitee files combined or
     consolidated tax returns in such state or local jurisdiction, respectively,
     with one or more Affiliates which are also Tax Indemnitee, (C) any foreign
     government or any political subdivision or taxing authority thereof or any
     territory or possession of the United States or by any international
     authority except to the extent such Income Taxes would not have been

                                       37
<PAGE>

     imposed by such jurisdiction but for the use, location, operation, presence
     or registration of any Unit or part thereof in such jurisdiction or the
     activities of the Lessee or any of its Affiliates in such jurisdiction or
     the making of any payments from such jurisdiction by or on behalf of the
     Lessee pursuant to the Operative Agreements or any other nexus between such
     jurisdiction and the transactions contemplated by the Operative Agreements
     (other than such nexus as may result solely from the activities, presence,
     ownership or receipts of such Tax Indemnitee in each case unrelated to the
     Operative Agreements or transactions contemplated thereby) or (D) any
     government or jurisdiction described in (A), (B) or (C) of this clause (i)
     because the applicable Tax Indemnitee is not a resident of the United
     States for tax purposes.

          (ii)  Taxes imposed with respect to any period after the earliest of
     the applicable dates of (x) the return of possession of the Equipment to
     the Owner Participant or the placement of the Equipment in storage at the
     request of the Owner Participant, in either case pursuant to Section 6 of
     the Lease, (y) the termination of the Lease Term pursuant to Section 22.1
     or Section 22.3 of the Lease, or (z) the discharge in full of the Lessee's
     obligation to pay the Termination Value or the Stipulated Loss Value and
     all other amounts due, if any, under Section 10 or 11.2 of the Lease, as
     the case may be, with respect to the Equipment; provided that the exclusion
                                                     --------
     set forth in this clause (ii) shall not apply to Taxes to the extent such
     Taxes relate to events occurring or matters arising prior to or
     simultaneously with the applicable time;

          (iii) As to any Tax Indemnitee, Taxes to the extent caused by any
     misrepresentation or breach of warranty or covenant under the Operative
     Agreements by such Tax Indemnitee, or by the gross negligence or willful
     misconduct of such Tax Indemnitee;

          (iv)  As to any Tax Indemnitee, Taxes which become payable as a result
     of a sale, assignment, transfer or other disposition (whether voluntary or
     involuntary) by such Tax Indemnitee of all or any portion of its interest
     in the Equipment or any part thereof, the Trust Estate or any of the
     Operative Agreements or rights created thereunder other than as a result of
     the substitution, modification or improvement of the Equipment or any part
     thereof or a disposition which occurs as the result of the exercise of
     remedies for a Lease Event of Default, any disposition which occurs during
     the continuance of a Lease Event of Default or a purchase of any Unit
     pursuant to the Lease; provided, that, notwithstanding the foregoing but
                            --------
     subject to the Tax Indemnity Agreement, Lessee shall not be obligated to
     indemnify any Tax Indemnitee with respect to net income taxes imposed
     within the United States as the result of a sale, assignment, transfer or
     other disposition by such Tax Indemnitee or any Taxes imposed as a result
     of the status of the Tax Indemnitee as other than a resident of the United
     States for tax purposes;

          (v)   Taxes which result from the Owner Trustee's engaging on behalf
     of the Trust Estate in transactions unrelated to those permitted or
     contemplated by the Operative Agreements;

          (vi)  As to any Tax Indemnitee, Taxes to the extent they exceed the
     Taxes that would have been imposed had the initial Tax Indemnitee not
     transferred, sold or

                                       38
<PAGE>

     otherwise disposed of any interest held by such Tax Indemnitee pursuant to
     any of the Operative Agreements such excess to be determined based on a
     certificate of the original Tax Indemnitee provided to the Lessee
     immediately prior to a transfer, sale or other such disposition of such
     interest, such certificate to set forth the state and local jurisdictions
     in which the original Tax Indemnitee would not be entitled to
     indemnification in accordance with (S) 7.1(c)(i)(B) and (C) hereof,
     provided, however, that this provision shall not apply to the determination
     --------  -------
     of amounts required to make payments on an After-Tax Basis; and

          (vii) Taxes imposed on the Owner Trustee based on the Owner Trustee's
     fee for services under the Trust Agreement.

     (d)  All Tax Obligations in this Section, etc.  Notwithstanding any other
provision anywhere contained in the Operative Agreements, it is understood that
except as provided in Section 6.2, with respect to the Owner Participant, and
Section 6.3, with respect to the Owner Trustee, and except as provided in
Section 5.03 of the Indenture, the Owner Participant and the Owner Trustee shall
have no obligations with respect to Taxes or other charges to the Indenture
Trustee or the Loan Participant imposed under Section 7.16 of the Pass Through
Trust Agreement or Section 5.09 of the Indenture, or otherwise.

     (e)  Payments to Lessee.

          (i)   If any Tax Indemnitee shall realize a Tax benefit (net of any
     Tax detriment not otherwise paid or indemnified against by the Lessee
     hereunder) as a result of any Taxes paid or indemnified against by the
     Lessee under this Section 7.1 (whether by way of deduction, credit,
     allocation or apportionment or otherwise), such Tax Indemnitee shall pay to
     the Lessee an amount equal to the amount of such Tax benefit, increased by
     the Tax Indemnitee's additional saved Taxes attributable to the payment
     being made to the Lessee hereunder; provided, however, that in no event
                                         --------  -------
     shall the aggregate amount paid by any Tax Indemnitee to the Lessee with
     respect to any realized Tax benefit exceed the aggregate amount previously
     advanced by the Lessee with respect to such Taxes (in each case, computed
     on a pre-tax basis) but provided, further, that such excess shall be
                             --------  -------
     carried forward to reduce or offset any future obligations of the Lessee to
     such Tax Indemnitee under this Section 7.1.

          (ii)  Upon receipt by a Tax Indemnitee of a refund or credit of all or
     part of any Taxes paid or indemnified against by the Lessee, such Tax
     Indemnitee shall pay to the Lessee an amount equal to the amount of such
     refund plus any interest received by or credited to such Tax Indemnitee
     with respect to such refund increased or decreased, as the case may be, by
     the Tax Indemnitee's net additional or saved taxes attributable to the
     receipt of such amounts from the taxing authority and the payment being
     made to the Lessee hereunder.

          (iii) The Tax Indemnitee shall in good faith file its Tax returns and
     deal with taxing authorities to seek and claim any such tax benefits or
     refunds.

          (iv)  Any disallowance or other loss of a tax refund, credit, savings
     or other benefit by a Tax Indemnitee, which refund, credit, savings or
     other benefit was taken into

                                       39
<PAGE>

     account under this Section 7.1, shall be treated as a tax indemnifiable by
     the Lessee under this Section 7.1 without regard to the exclusions in
     Section 7.1(c) (other than clause (iii).

     (f) Procedures.  Any amount payable to a Tax Indemnitee pursuant to
paragraph (b) shall be paid within 30 days after receipt of a written demand
therefor from such Tax Indemnitee accompanied by a written statement describing
in reasonable detail the basis for such indemnity and the computation of the
amount so payable, provided that such amount need not be paid prior to (i) the
                   --------
date which is the Business Day before the date on which such Taxes are due (but
in no event before the taxable year of the Tax Indemnitee in which such Taxes
are due), or (ii) in the case of amounts which are being contested pursuant to
paragraph (g) hereof, subject to the requirement of an advance in clause (vi) of
the second paragraph of paragraph (g) hereof, the time such Taxes are due and
payable pursuant to the resolution of such contest (including all appeals).  Any
amount payable to the Lessee pursuant to paragraph (e) shall be paid within 30
days after the Tax Indemnitee realizes a net tax benefit or receives a refund
giving rise to a payment under paragraph (e), and shall be accompanied by a
written statement by the Tax Indemnitee setting forth in reasonable detail the
basis for computing the amount of such payment.  Within 15 days following the
Lessee's receipt of any computation from the Tax Indemnitee, the Lessee may
request that the accounting firm that regularly prepares the certified financial
statements of the Tax Indemnitee determine whether such computations of the Tax
Indemnitee are correct.  Such accounting firm shall be requested to make the
determination contemplated by this paragraph (f) within 30 days of its
selection.  In the event such accounting firm shall determine that such
computations are incorrect, then such firm shall determine what it believes to
be the correct computations.  The Tax Indemnitee shall cooperate with such
accounting firm and supply it with all information necessary to permit it to
accomplish such determination on a confidential basis.  The computations of such
accounting firm shall be final, binding and conclusive upon the parties and the
Lessee shall have no right to inspect the books, records or tax returns of the
Tax Indemnitee to verify such computation or for any other purpose. All fees and
expenses of the accounting firm payable under this Section 7.1(f) shall be borne
by the Lessee except that if such accounting firm determines that the Tax
Indemnitee's computations were incorrect and understated the payments owing to
the Lessee or overstated the payments owing to such Tax Indemnitee by 10% or
more of the correct amount as determined by such accounting firm, then the Tax
Indemnitee shall bear the fees and expenses of such accounting firm.

     (g) Contest.  If a written claim is made against a Tax Indemnitee for Taxes
with respect to which the Lessee may be liable for indemnity hereunder, the Tax
Indemnitee shall give the Lessee prompt notice in writing of such claim (and in
any event within 30 days after its receipt) and shall promptly furnish the
Lessee with copies of the claim and all other writings received from the taxing
authority relating to the claim; provided however, that the failure of such Tax
                                 -------- -------
Indemnitee timely to provide such written notice shall not affect the Lessee's
obligations under this Section 7.1(g) except to the extent that the same
materially adversely affects the ability of the Lessee to contest such Taxes.
The Tax Indemnitee shall not pay such claim prior to 30 days after providing the
Lessee with such written notice, unless required to do so by law or unless
deferral of payment might, in the reasonable good faith judgment of the Tax
Indemnitee, cause material adverse consequences to the Tax Indemnitee or result
in the creation of any Lien other than a Permitted Lien.  The Tax Indemnitee
shall in good faith, with due diligence and at the Lessee's expense, if
requested in writing by the Lessee, contest (including

                                       40
<PAGE>

pursuing all appeals permitted hereby) in the name of the Tax Indemnitee (or, if
requested by the Lessee and permissible as a matter of law, in the name of the
Lessee), or shall permit the Lessee to contest in either the name of the Lessee
or with the Tax Indemnitee's consent, in the name of the Tax Indemnitee the
validity, applicability or amount of such Taxes by,

          (i)   resisting payment thereof if practical;

          (ii)  not paying the same except under protest if protest is necessary
     and proper;

          (iii) if the payment be made, using reasonable efforts to obtain a
     refund thereof in appropriate administrative and judicial proceedings; or

          (iv)  taking such other reasonable action as is reasonably requested
     by the Lessee from time to time.

provided, however, that to the extent the contest is carried on in the name of
--------  -------
the Lessee or an Affiliate, or is brought in the name of a Tax Indemnitee and
involves only Taxes for which the Lessee is or will be liable hereunder, such
contest shall be undertaken by the Lessee at the Lessee's expense (unless at any
time the Tax Indemnitee determines in its reasonable good faith judgment that
based upon the Lessee's conduct of such contest the Lessee's control of such
contest would cause material adverse consequences or a material risk thereof to
the Tax Indemnitee) and at no-after-tax cost to any Tax Indemnitee (a "Lessee
Controlled Contest"), but if such contest would involve any other Taxes or any
Taxes in the nature of a tax on net income then such Tax Indemnitee may in its
sole discretion control such contest (including selecting the forum for such
contest) (an "Indemnified Person Controlled Contest").

     In no event shall any Tax Indemnitee be required or the Lessee be permitted
to contest any Taxes for which the Lessee is obligated to indemnify pursuant to
this Section unless: (i) such Lessee shall have acknowledged its liability to
such Tax Indemnitee for an indemnity payment pursuant to this Section as a
result of such claim if and to the extent such Indemnitee or the Lessee, as the
case may be, shall not prevail in the contest of such claim; (ii) such Tax
Indemnitee shall have received the opinion of tax counsel (which may, in the
case of Taxes imposed by a taxing authority located in the United States,
include in-house counsel of the Lessee) selected by the Lessee and satisfactory
to the Tax Indemnitee furnished at Lessee's sole expense, to the effect that a
reasonable basis consistent with ABA Opinion 85-352 exists for contesting such
claim or, in the event of an appeal, that it is more likely than not that an
appellate court will reverse or substantially modify the adverse determination
(and provided that no appeal shall be required to the United States Supreme
Court); (iii) the Lessee shall have agreed to pay such Tax Indemnitee on demand
(and at no after-tax cost to any Tax Indemnitee) all reasonable costs and
expenses that such Tax Indemnitee actually incurs in connection with contesting
such claim (including, without limitation, all costs, expenses, reasonable legal
and accounting fees, disbursements, penalties, interest and additions to the
Taxes); (iv) no Lease Event of Default shall have occurred and shall be
continuing; (v) such Tax Indemnitee shall have determined that the action to be
taken will not result in any risk of imposition of criminal penalties or
substantial danger of sale, forfeiture or loss of, or the creation of any Lien
(except if such Lessee shall have adequately bonded such Lien or otherwise made
provision to protect the interests of such Tax

                                       41
<PAGE>

Indemnitee in a manner reasonably satisfactory to such Tax Indemnitee) on the
Equipment or any portion thereof or any interest therein; and (vi) if such
contest shall be conducted in a manner requiring the payment of the claim, the
Lessee shall have paid the amount required (at no after-tax cost to such Tax
Indemnitee). The Lessee shall cooperate with the Tax Indemnitee with respect to
any contest controlled and conducted by the Tax Indemnitee and the Tax
Indemnitee shall consult with the Lessee regarding the conduct of such contest.
The Tax Indemnitee shall cooperate with the Lessee with respect to any contest
controlled and conducted by the Lessee and the Lessee shall consult with the Tax
Indemnitee regarding the conduct of such contest.

     In no event will a Tax Indemnitee be required to contest in an Indemnified
Person Controlled Contest any Taxes if such Tax Indemnitee shall waive its right
to an indemnity under this Section 7.1 except that a Tax Indemnitee shall not be
permitted to waive or not contest any Lessee Controlled Contest without Lessee's
consent.  Unless a Tax Indemnitee obtains the consent of the Lessee, which
consent shall not be unreasonably withheld (provided, however, the Lessee shall
                                            --------  -------
not be considered to have unreasonably withheld such consent because of (i) any
failure by the Lessee to consider any issue or dispute of the Tax Indemnitee not
directly related to the claim giving rise to the contest rights in issue or (ii)
the Lessee's consideration of the effects of such settlement on issues of the
Lessee which are not the subject of such claim), the failure to contest or the
settlement of any contest required under Section 7.1 by a Tax Indemnitee shall
constitute a waiver by such Tax Indemnitee of its rights to indemnification
hereunder as to such contest and as to any future claims for which the Lessee's
right to contest shall have been precluded by such Tax Indemnitee' failure to
contest.

     (h) For purposes of this Section 7.1, in determining the order in which any
Tax Indemnitee utilizes withholding or other foreign taxes as a credit against
such Tax Indemnitee's United States income taxes, such Tax Indemnitee shall be
deemed to utilize (i) first, all foreign taxes other than those described in
clause (ii) below; provided, however, that such other foreign taxes which are
                   --------  -------
carried back to the taxable year for which a determination is being made (other
than any carrybacks which are known to be available at the time such
determination is made) pursuant to this clause (i) shall be deemed utilized
after the foreign taxes described in clause (ii) below, and (ii) then, on a pro
rata basis, all foreign taxes (including fees, taxes and other charges
hereunder) with respect to which such Tax Indemnitee is entitled to obtain
indemnification pursuant to an indemnification provision contained in any lease,
loan agreement, financing document or participation agreement (including the
Lease).

     (i) In the event any reports with respect to Taxes are required to be made,
the Lessee will either prepare and file such reports (and in the case of reports
which are required to be filed on the basis of individual items of Equipment,
such reports shall be prepared and filed in such manner as to show as required
the interests of each Tax Indemnitee in such item of Equipment) or, if it shall
not be permitted to file the same, it will notify each Tax Indemnitee in writing
of such reporting requirements, prepare such reports in such manner as shall be
reasonably satisfactory to each Tax Indemnitee and deliver the same to each Tax
Indemnitee within a reasonable period prior to the date the same is to be filed.
The Lessee shall provide such information as the Owner Participant or the Lessor
may reasonably require from the Lessee to enable the Owner Participant and the
Lessor to pursue or fulfill their respective tax filing, tax audit, and tax
litigation rights and obligations.

                                       42
<PAGE>

     (j) The provisions of this Section 7.1 shall continue in full force and
effect, notwithstanding the expiration or termination of any Operative
Agreement, until all obligations hereunder have been met and all liabilities
hereunder paid in full.

     (k) Any amount payable to the Lessee pursuant to the terms of this Section
7.1 shall not be paid or retained by the Lessee if at the time of such payment
or retention a Material Default or a Lease Event of Default shall have occurred
and be continuing.  Such otherwise paid or retained amounts may be applied by
the related Tax Indemnitee to satisfy the obligations of the Lessee under the
Operative Agreements.  At such time as there shall not be continuing any such
Material Default or Lease Event of Default, such amount shall be paid to the
Lessee without interest to the extent not previously applied in accordance with
the preceding sentence.

     (l) For purposes of this Section 7.1, the term "Income Tax" means any Tax
based on or measured by or with respect to gross, adjusted gross or net income
(including without limitation, capital gains taxes, minimum taxes and tax
preferences) or gross or net receipts and Taxes which are capital, net worth,
conduct of business, franchise or excess profits taxes and interest, additions
to tax, penalties, or other charges in respect thereof (provided, however, that
                                                        --------  -------
sales, use, rental, excise, or property taxes shall not constitute an Income
Tax; and provided, further, that a value-added tax shall constitute an Income
         --------  -------
Tax if it is in the nature of a tax on net income but shall not constitute an
Income Tax if it is in the nature of a sales, use, rental, excise, property or
other tax; and provided, further, that a withholding tax shall not constitute an
               --------  -------
Income Tax notwithstanding its being a tax that is based on or measured by or
with respect to gross income or gross receipts).

     (m) Withholding.  The Pass Through Trustee shall withhold any Taxes
required to be withheld on payments to any holder of a Pass Through Certificate
who is a Non-U.S. Person except to the extent that such a holder of a Pass
Through Certificate has furnished evidence to the Pass Through Trustee
sufficient under applicable law to entitle such holder of a Pass Through
Certificate to any exemption from or reduction in the rate of withholding on
interest claimed by such holder of a Pass Through Certificate.  The Indenture
Trustee shall withhold any Taxes required to be withheld on any payment to a
Holder pursuant to Section 5.09 of the Indenture.  If the Indenture Trustee or
Pass Through Trustee fails to withhold a Tax required to be withheld with
respect to any Certificateholder or any claim is otherwise asserted by a taxing
authority against the Owner Trustee or Owner Participant for any withholding
tax, the Lessee will indemnify the Owner Trustee and the Owner Participant
(without regard to the exclusions set forth in Section 7.1(c) hereof) on an
After-Tax Basis against any such Taxes required to be withheld and any interest
and penalties with respect thereto, along with any other reasonable out-of-
pocket costs (including reasonable attorney's fees) incurred in connection with
any such claim.  The Indenture Trustee or the Pass Through Trustee, as the case
may be, in its individual capacity (and without recourse to the Indenture
Estate), shall indemnify the Lessee (without regard to the exclusions set forth
in Section 7.1(c) hereof) on an After-Tax Basis for any payment the Lessee shall
have made pursuant to the preceding sentence.

     Section 7.2 General Indemnification and Waiver of Certain Claims.
                 ----------------------------------------------------

strict or absolute liability or liability in tort) which may be imposed on,
incurred by, suffered by, or asserted against an Indemnified Person, as defined
herein, or any Unit and, except as otherwise expressly provided in this Section
7.2, shall include, but not be limited to, all reasonable out-of-pocket costs,

by an Indemnified Person in connection therewith or related thereto.

     (b) Indemnified Person Defined.  For the purposes of this Section 7.2,

Affiliates and each of their respective directors, officers, employees,
successors and permitted assigns, agents and servants, the Trust Estate and the
Indenture Estate (the respective directors, officers, employees, successors and
permitted assigns, agents and servants of the Owner Participant, the Owner
Trustee, the Trust Company, the Indenture Trustee, the Pass Through Trustee and
each of their Affiliates, as applicable, together with the Owner Participant,
the Owner Trustee, the Indenture Trustee, the Pass Through Trustee and each of
their Affiliates, as the case may be, being referred to herein collectively as
the "Related Indemnitee Group" of the Owner Participant, the Indenture Trustee,
the Owner Trustee and the Pass Through Trustee, respectively).

     (c) Claims Indemnified.  Whether or not any Unit is accepted under the
Lease, or a closing occurs with respect thereto, and subject to the exclusions
stated in subsection (d) below, Lessee agrees to indemnify, protect, defend and
hold harmless each Indemnified Person on an After-Tax Basis against Claims
directly or indirectly resulting from or arising out of or alleged to result
from or arise out of (whether or not such Indemnified Person shall be
indemnified as to such Claim by any other Person):

         (i)  this Agreement or any other Operative Agreement or any of the
     transactions contemplated hereby and thereby or any Unit or the ownership,
     lease, operation, possession, modification, improvement, abandonment, use,
     non-use, maintenance, sublease, substitution, control, repair, storage,
     alteration, transfer or other application or disposition, return, overhaul,
     testing, servicing, replacement or registration of any Unit (including,
     without limitation, injury, death or property damage of passengers,
     shippers or others, and environmental control, noise and pollution
     regulations, or the presence, discharge, spillage, release or escape of
     Hazardous Substances or damage to the environment (including, without
     limitation, clean-up costs, response costs, costs of corrective actions and
     natural resource damages)) whether or not in compliance with the terms of
     the Lease, or by any of the commodities, items or materials from time to
     time contained in any Unit, whether or not in compliance with the terms of
     the Lease, or by the inadequacy of any Unit or deficiency or defect in any
     Unit or by any other circumstances in connection with any Unit, or by the
     performance of any Unit or any risks relating thereto, or by any
     interruption of service, loss of business or anticipated profits or
     consequential damages;

         (ii) the construction, manufacture, financing, refinancing, design,
     purchase, acceptance, rejection, delivery, non-delivery or condition of any
     Unit (including, without limitation, latent and other defects, whether or
     not discoverable, and any claim for patent, trademark or copyright
     infringement);

                                       44
<PAGE>

          (iii) any act or omission (whether negligent or otherwise) or any
     breach of or failure to perform or observe, or any other non-compliance
     with, any covenant, condition or agreement to be performed by, or other
     obligation of, Lessee under any of the Operative Agreements, or the falsity
     of any representation or warranty of the Lessee in any of the Operative
     Agreements or in any document or certificate delivered in connection
     therewith other than representations and warranties in the Tax Indemnity
     Agreement;

          (iv)  the offer, sale or delivery of any Equipment Notes or Pass
     Through Certificates or any interest in the Trust Estate;

          (v)   any violation of law, rule, regulation or order by the Lessee or
     any sublessee or their respective directors, officers, employees, agents or
     servants; and

          (vi)  the acquisition or holding of any Equipment Notes or Pass
     Through Certificates being deemed to result in a "prohibited transaction"
     under ERISA or the Code.

     (d)  Lessee's Claims Excluded.  The following are excluded from the
agreement to indemnify under this Section 7.2:

          (i)   Claims with respect to any Unit to the extent attributable to
     acts or events occurring after (A) in the case of the exercise by the
     Lessee of a purchase option with respect to such Unit under Section 22.1 or
     22.3 of the Lease, the exercise by the Lessee of an early termination
     option with respect to such Unit under Section 10 of the Lease, the
     occurrence or deemed occurrence of an Event of Loss with respect to such
     Unit under Section 11 of the Lease, or the election to replace such Unit
     under Section 8.1(b), 8.3 or 9.1 of the Lease, the last to occur of (x) the
     payment of all amounts due from the Lessee in connection with any such
     event, (y) the release of the Lien of the Indenture on such Unit, and (z)
     legal transfer of title to such Unit to any Person other than Lessor,
     except in the case of a retention of any Unit by Lessor pursuant to the
     terms and provisions of Section 10.3 of the Lease, and in the case of any
     such retention, upon the effective date of the termination of the Lease
     Term with respect to such Unit retained by Lessor pursuant to Section 10.3
     or (B) in all other cases (except in any case where remedies are being
     exercised under Section 15 of the Lease), the last to occur of (x) with
     respect to such Unit, the earlier to occur of the termination of the Lease
     or the expiration of the Lease Term in accordance with the terms thereof,
     (y) with respect to each Unit, the return of such Unit to the Lessor in
     accordance with the terms of the Lease (it being understood that, so long
     as any Unit is in storage as provided in Section 6.1(c) of the Lease, the
     date of return thereof for the purpose of this clause (B) shall be the last
     day of the Storage Period), and (z) the release of the Lien of the
     Indenture on such Unit;

          (ii)  Claims which are Taxes, whether or not the Lessee is required to

                                       45
<PAGE>

          (iii) with respect to any particular Indemnified Person, Claims to the
     extent resulting from (x) the gross negligence or willful misconduct of
     such Indemnified Person, or (y) any breach of any covenant to be performed
     by such Indemnified Person under any of the Operative Agreements, or the
     falsity of any representation or warranty of such Indemnified Person in any
     of the Operative Agreements or in a document or certificate delivered in
     connection therewith;

          (iv)  any Claim to the extent attributable to any transfer by the
     Lessor of the Equipment or any portion thereof or any transfer by the Owner
     Participant of all or any portion of its interest in the Trust Estate other
     than (A) any transfer after a Lease Default or Lease Event of Default, (B)
     the transfer of the Equipment or any Owner Participant's interest in the
     Equipment to the Lessee, (C) the transfer of the Equipment to a third party
     pursuant to Lessee's election to terminate the Lease or (D) any transfer of
     the Equipment pursuant to Section 6.9;

          (v)   with respect to any particular Indemnified Person, any Claim
     resulting from the imposition of any Lessor's Lien attributable to such
     Indemnified Person; or

          (vi)  with respect to any particular Indemnified Person, any Claim, to
     the extent the risk thereof has been expressly assumed by such Indemnified
     Person in connection with the exercise by such Indemnified Person of the
     right of inspection or restenciling granted under Section 6.1 of the Lease
     or right of inspection granted under Sections 6.2 or 13.2 of the Lease.

     (e)  Insured Claims.  In the case of any Claim indemnified by the Lessee
hereunder which is covered by a policy of insurance maintained by the Lessee
pursuant to Section 12 of the Lease or otherwise, each Indemnified Person agrees
to provide reasonable cooperation to the insurers in the exercise of their
rights to investigate, defend or compromise such Claim as may be required to
retain the benefits of such insurance with respect to such Claim.

     (f)  Claims Procedure.  An Indemnified Person shall, after obtaining
knowledge thereof, promptly notify the Lessee of any Claim as to which
indemnification is sought; provided, however, that the failure to give such
                           --------  -------
notice shall not release the Lessee from any of its obligations under this
Section 7.2, except to the extent that failure to give notice of any action,
suit or proceeding against such Indemnified Person shall have a material adverse
affect on Lessee's ability to defend such Claim or recover proceeds under any
insurance policies maintained by Lessee hereunder.  The Lessee shall, after
obtaining knowledge thereof, promptly notify each Indemnified Person of any
indemnified Claim affecting such Person.  Subject to the provisions of the
following paragraph, the Lessee shall at its sole cost and expense be entitled
to control, and shall assume full responsibility for, the defense of such claim
or liability; provided that the Lessee shall keep the Indemnified Person which
              --------
is the subject of such proceeding fully apprised of the status of such
proceeding and shall provide such Indemnified Person with all information with
respect to such proceeding as such Indemnified Person shall reasonably request.

     Notwithstanding any of the foregoing to the contrary, the Lessee shall not
be entitled to control and assume responsibility for the defense of such claim
or liability if (1) a Lease Event of Default shall have occurred and be
continuing, (2) such proceeding will involve any material

                                       46
<PAGE>

danger of the sale, forfeiture or loss of, or the creation of any Lien (other
than any Lien permitted under the Operative Agreements or a Lien which is
adequately bonded to the satisfaction of such Indemnified Person) on, any Unit,
(3) the amounts involved, in the good faith opinion of such Indemnified Person,
are likely to have a materially adverse effect on the business of such
Indemnified Person other than the ownership, leasing and financing of the
Equipment, (4) in the good faith opinion of such Indemnified Person, there
exists an actual or potential conflict of interest such that it is advisable for
such Indemnified Person to retain control of such proceeding or (5) such claim
or liability involves the possibility of criminal sanctions or liability to such
Indemnified Person. In the circumstances described in clauses (1) - (5), the
Indemnified Person shall be entitled to control and assume responsibility for
the defense of such claim or liability at the expense of the Lessee. In
addition, any Indemnified Person may participate in any proceeding controlled by
the Lessee pursuant to this Section 7.2, at its own expense, in respect of any
such proceeding as to which the Lessee shall have acknowledged in writing its
obligation to indemnify the Indemnified Person pursuant to this Section 7.2, and
at the expense of Lessee in respect of any such proceeding as to which the
Lessee shall not have so acknowledged its obligation to the Indemnified Person
pursuant to this Section 7.2. Lessee may in any event participate in all such
proceedings at its own cost. Nothing contained in this Section 7.2(f) shall be
deemed to require an Indemnified Person to contest any Claim or to assume
responsibility for or control of any judicial proceeding with respect thereto.

     (g)    Subrogation. If a Claim indemnified by the Lessee under this Section
7.2 is paid in full by the Lessee and/or an insurer under a policy of insurance
maintained by the Lessee, the Lessee and/or such insurer, as the case may be,
shall be subrogated to the extent of such payment to the rights and remedies of
the Indemnified Person (other than under insurance policies maintained by such
Indemnified Person) on whose behalf such Claim was paid with respect to the
transaction or event giving rise to such Claim. So long as no Lease Event of
Default shall have occurred and be continuing, should an Indemnified Person
receive any refund, in whole or in part, with respect to any Claim paid by the
Lessee hereunder, it shall promptly pay over the amount refunded (but not in
excess of the amount the Lessee or any of its insurers has paid) to the Lessee.

     (h)    Waiver of Certain Claims. The Lessee hereby waives and releases any
Claim now or hereafter existing against any Indemnified Person arising out of
death or personal injury to personnel of the Lessee, pollution incidents, loss
or damage to property of the Lessee, or the loss of profits or use of any
property of the Lessee, which may result from or arise out of the condition, use
or operation of the Equipment during the Lease Term, including without
limitation any latent or patent defect whether or not discoverable.

     (i)    No Guaranty. The general indemnification provisions of this Section
7.2 do not constitute a guaranty by the Lessee that the principal of, interest
on or any amounts payable with respect to the Equipment Notes will be paid.

 SECTION 8. LESSEE'S RIGHT OF QUIET ENJOYMENT.

     Each party to this Agreement acknowledges notice of, and consents in all
respects to, the terms of the Lease, and expressly, severally and as to its own
actions only, agrees that, so long as no Lease Event of Default has occurred and
is continuing, it shall not take or cause to be taken

                                       47
<PAGE>

any action contrary to Lessee's rights under the Lease, including, without
limitation, the right to possession, use and quiet enjoyment by Lessee or any
permitted sublessee of the Equipment.

 SECTION 9.  SUCCESSOR INDENTURE TRUSTEE.

     In the event that the Indenture Trustee gives notice of its resignation
pursuant to Section 8.02 of the Trust Indenture, the Owner Trustee shall
promptly appoint a successor Indenture Trustee reasonably acceptable to the
Lessee and the Pass Through Trustee.

 SECTION 10. MISCELLANEOUS.

     Section 10.1 Consents. Each Participant covenants and agrees (subject, in
                  --------
the case of the Loan Participant, to all of the terms and provisions of the
Trust Indenture) that it shall not unreasonably withhold its consent to any
consent requested of the Owner Trustee or the Indenture Trustee, as the case may
be, under the terms of the Operative Agreements that by its terms is not to be
unreasonably withheld by the Owner Trustee or the Indenture Trustee.

     Section 10.2 Refinancing.  So long as no Lease Default or Lease Event of
                  -----------
Default shall be in existence (on the date of request or at any time through and
including the Refunding Date, as defined below), the Lessee shall have the right
to request the Owner Participant and the Owner Trustee to effect an optional
prepayment of all, and not less than all, of the Equipment Notes pursuant to
Section 2.10(d) of the Indenture as part of a refunding or refinancing
operation.  As soon as practicable after receipt of such request, the Owner
Participant and the Lessee will enter into an agreement, in form and substance
reasonably satisfactory to the parties thereto, as to the terms of such
refunding or refinancing as follows:

     (a)     the Lessee, the Owner Participant, the Indenture Trustee, the Owner
Trustee, and any other appropriate parties will enter into a financing or loan
agreement (which may involve an underwriting agreement in connection with a
public offering), in form and substance reasonably satisfactory to the parties
thereto, providing for (i) the issuance and sale by the Owner Trustee or such
other party as may be appropriate on the date specified in such agreement (for
the purposes of this Section 10.2, the "Refunding Date") of debt securities in
an aggregate principal amount (in the lawful currency of the United States)
equal to the principal amount of the Equipment Notes outstanding on the
Refunding Date, having the same maturity date as said Equipment Notes and having
a weighted average life which is not less than or greater than the Remaining
Weighted Average Life of said Equipment Notes by more than three months, (ii)
the application of the proceeds of the sale of such debt securities to the
prepayment of all such Equipment Notes on the Refunding Date, and (iii) payment
by Lessee to the Person or Persons entitled thereto of all other amounts, in
respect of accrued interest, any Make-Whole Amount or other premium, if any,
payable on such Refunding Date;

     (b)     the Lessee and the Owner Trustee will amend the Lease in a manner
such that (i) if the Refunding Date is not a Rent Payment Date and the accrued
and unpaid interest on the Equipment Notes is not otherwise paid pursuant to
Section 10.2(a), the Lessee shall on the Refunding Date prepay that portion of
the next succeeding installment of Basic Rent as shall equal the aggregate
interest accrued on the Equipment Notes outstanding to the Refunding Date, (ii)
Basic Rent payable in respect of the period from and after the Refunding Date
shall be

                                       48
<PAGE>

recalculated to preserve the Net Economic Return which the Owner Participant
would have realized had such refunding not occurred, provided that the net
                                                     --------
present value of Basic Rent shall be minimized to the extent consistent
therewith, and (iii) amounts payable in respect of Stipulated Loss Value, Early
Purchase Price, Basic Term Purchase Price and Termination Value from and after
the Refunding Date shall be appropriately recalculated to preserve the Net
Economic Return which the Owner Participant would have realized had such
refunding not occurred (it being agreed that any recalculations pursuant to
subclauses (ii) and (iii) of this clause (b) shall be performed in accordance
with the requirements of Section 2.6 hereof);

     (c) the Owner Trustee will enter into an agreement to provide for the
securing thereunder of the debt securities issued by the Owner Trustee pursuant
to clause (a) of this Section 10.2 in like manner as the Equipment Notes and/or
will enter into such amendments and supplements to the Indenture as may be
necessary to effect such refunding or refinancing, which agreements, amendments
and/or supplements shall be reasonably satisfactory in form and substance to the
Owner Participant; provided that, no such agreement or amendment shall provide
                   --------
for any increase in the security for the new debt securities; and provided
                                                                  --------
further that, notwithstanding the foregoing (but subject to the provisions of
-------
clauses (a) and (b) above), the Lessee reserves the right to set the economic
terms and other terms not customarily negotiated between an owner participant
and a lender of the refunding or refinancing transaction to be so offered to the
extent that they are passed through to the Lessee in, or define rights or
obligations of the Lessee under, the Operative Agreements; provided, further,
                                                           --------  -------
that no such amendment or supplement will increase the obligations or impair the
rights of the Owner Participant under the Operative Agreements without the
consent of the Owner Participant;

     (d) in the case of a refunding or refinancing involving a public offering
of debt securities, neither the Owner Trustee nor the Owner Participant shall be
an "issuer" for securities law purposes or an "obligor" within the meaning of
the Trust Indenture Act of 1939, as amended, the offering materials (including
any registration statement) for the refunding or refinancing transaction shall
be reasonably satisfactory to the Owner Participant and the Lessee shall provide
satisfactory indemnity to the Owner Trustee and Owner Participant with respect
thereto;

     (e) unless otherwise agreed by the Owner Participant, the Lessee shall pay
to the Owner Trustee as Supplemental Rent an amount equal to the Make-Whole
Amount or other premium, if any, payable in respect of Equipment Notes
outstanding on the Refunding Date, and all reasonable fees, costs, expenses of
such refunding or refinancing and of the parties hereto incurred in connection
with such refunding or refinancing (including all reasonable out-of-pocket legal
fees and expenses);

     (f) the Lessee shall give the Indenture Trustee not less than 25 days prior
written notice of the Refunding Date;

     (g) the Owner Participant, the Owner Trustee, the Indenture Trustee and the
Pass Through Trustee shall have received (i) such opinions of counsel as they
may reasonably request concerning compliance with the Securities Act of 1933, as
amended, and any other applicable law relating to the sale of securities and
(ii) such other opinions of counsel and such certificates and other documents,
each in form and substance satisfactory to them, as they may reasonably request
in connection with compliance with the terms and conditions of this Section
10.2; and

<PAGE>

     (h) all necessary authorizations, approvals and consents shall have been
obtained;

provided, however, that the Lessee will, to the extent then known, promptly
--------  -------
provide to the Owner Participant, the Owner Trustee, the Indenture Trustee and
the Pass Through Trustee substantially final terms and conditions of any such
refunding or refinancing within 30 days prior to the execution and delivery of
the documents contemplated hereunder in connection therewith; and provided,
                                                                  --------
further, that (v) no refunding or refinancing of the Equipment Notes will be
-------
permitted unless within 20 days after receipt by the Owner Participant of a
request from the Lessee to effect a refunding or refinancing pursuant to this
Section 10.2 and of information regarding the terms of such refunding or
refinancing necessary to render the opinion referred to below, the Lessee has
provided the Owner Participant with (a) a tax opinion from Vedder, Price,
Kaufman & Kammholz or other tax counsel reasonably acceptable to the Owner
Participant to the effect that the Owner Participant would have a reasonable
basis within the meaning of Section 6662(d)(2)(B)(ii) of the Code not to report
any adverse federal income tax consequences as a result of such refunding or
refinancing and (b) an agreement to indemnify the Owner Participant against any
adverse tax consequence suffered as a result of such refinancing or refunding;
alternatively, in the event such reasonable basis tax opinion cannot be provided
and the Lessee wishes to effect such refunding or refinancing, the Lessee will,
at such time as the Lessee receives written notice from the Owner Participant
that the Owner Participant has filed any income tax return wherein such adverse
income tax consequences are recognized, make an indemnity payment to the Owner
Participant in the incremental amount of such adverse tax consequence (on an
After-Tax Basis) attributable to such refunding or refinancing; (w) the Lessee
shall pay to or reimburse the Participants, the Owner Trustee and the Indenture
Trustee for all costs and expenses (including reasonable attorneys' and
accountants' fees) paid or incurred by them in connection with such refunding or
refinancing; (x) no refunding or refinancing of the Equipment Notes will be
permitted if it shall cause the Owner Participant to account for the transaction
contemplated hereby as other than a "leveraged lease" under the Financial
Accounting Standards Board ("FASB") Statement No. 13, as amended (including any
amendment effected by means of the adoption by FASB of a new statement in lieu
of FASB Statement No. 13); and (y) in no event, in connection with or after
giving effect to such refunding or refinancing shall the Owner Participant be
exposed to any unindemnified risk or liability (including tax risk) to which it
is not exposed prior to such refunding or refinancing.

     Section 10.3 Amendments and Waivers.  Except as otherwise provided in the
                  ----------------------
Indenture, no term, covenant, agreement or condition of this Agreement may be
terminated, amended or compliance therewith waived (either generally or in a
particular instance, retroactively or prospectively) except by an instrument or
instruments in writing executed by each party against which enforcement of the
termination, amendment or waiver is sought.

     Section 10.13 Limitations of Liability.
                   ------------------------

     (a) Liabilities of Participants.  Neither the Indenture Trustee, the Owner
Trustee nor any Participant shall have any obligation or duty to the Lessee, to
any other Participant or to others with respect to the transactions contemplated
hereby, except those obligations or duties of such Participant expressly set
forth in this Agreement and the other Operative Agreements, and neither the
Indenture Trustee nor any Participant shall be liable for performance by any
other party hereto of such other party, obligations or duties hereunder.
Without limitation of the generality of the foregoing, under no circumstances
whatsoever shall the Indenture Trustee or any Participant be liable to the
Lessee for any action or inaction on the part of the Owner Trustee in connection
with the transactions contemplated herein, whether or not such action or
inaction is caused by willful misconduct or gross negligence of the Owner
Trustee unless such action or inaction is at the direction of the Indenture
Trustee or any Participant, as the case may be, and such direction is expressly
permitted hereby.

     (b) No Recourse to the Owner Trustee.  It is expressly understood and
agreed by and between the Owner Trustee, the Lessee, the Owner Participant, the
Indenture Trustee, and the Loan Participant, and their respective successors and
permitted assigns that, subject to the proviso contained in this Section
10.13(b), all representations, warranties and undertakings of the Owner Trustee
hereunder shall be binding upon the Owner Trustee, only in its capacity as Owner
Trustee under the Trust Agreement, and (except as expressly provided herein) the
Trust Company shall not be liable in its individual capacity for any breach
thereof, except for its gross negligence or willful misconduct, or for breach of
its covenants, representations and warranties contained herein, except to the
extent covenanted or made in its individual capacity; provided, however, that
                                                      --------  -------
nothing in this Section 10.13(b) shall be construed to limit in scope or
substance those representations and warranties of the Trust Company made
expressly in its individual capacity set forth herein.  The term "Owner Trustee"
as used in this Agreement shall include any successor trustee under the Trust
Agreement, or the Owner Participant if the trust created thereby is revoked.

     Section 10.14 Maintenance of Non-Recourse Debt.  The parties hereto agree
                   --------------------------------
that if the Owner Trustee becomes a debtor subject to the reorganization
provisions of the Bankruptcy Code, 11 U.S.C. (S)101 et seq. (the "Bankruptcy
Code") or any successor provision, the parties hereto will make an election
under 1111(b)(1)(A)(i) of the Bankruptcy Code.  If (a) the Owner Trustee becomes
a debtor subject to the reorganization provisions of the Bankruptcy Code or any
successor provision, (b) pursuant to such reorganization provisions the Owner
Trustee is required, by reason of the Owner Trustee being held to have recourse
liability to the Pass Through Trustee or the Indenture Trustee, directly or
indirectly, to make payment on account of any amount payable under the Equipment
Notes or any of the other Operative Agreements and (c) the Pass Through Trustee
and/or the Indenture Trustee actually receives any Excess Amount (as hereinafter
defined) which reflects any payment by the Owner Trustee on account of (b)
above, then the Pass Through Trustee and/or the Indenture Trustee, as the case
may be, shall promptly refund to the Owner Trustee such Excess Amount.  For
purposes of this Section 10.14 "Excess Amount" means the amount by which such
payment exceeds the amount which would have been received by the Pass Through
Trustee or the Indenture Trustee if the Owner Trustee had not become subject to
the recourse liability referred to in (b) above.

     Section 10.15 Ownership of and Rights in Units.  The sale of the Units
                   --------------------------------
contemplated hereby is intended for all purposes to be a true sale of all of the
Lessee's right, title and interest in and to the Units to the Owner Trustee,
which shall be the legal owner thereof.  Upon consummation of the sale and
leaseback transactions contemplated hereby, the Lessee's interest in the Units
is intended to be that of a lessee only.  It is intended that for federal and
state income tax purposes the Owner Participant will be the owner of the Units.
The rights of the Indenture Trustee in and to the Units pursuant to the
Indenture is intended to be that of a secured party holding a security interest,
subject to the Lease and the rights of the Lessee thereunder.  No holder of an
Equipment Note is intended to have any right, title or interest in or to the
Units except as a beneficiary of the security interest granted by the Owner
Trustee to the Indenture Trustee pursuant to the Indenture in trust for the
equal and ratable benefit of the holders from time to time of the Equipment
Notes.

     Section 10.16  Deferred Payment for Early Purchase Option.  If Lessee
                    ------------------------------------------
elects to exercise an early purchase option pursuant to Section 22.1(b) of the
Lease with respect to Units in a Basic Group, Lessee may, at its option, either
(x) pay the entire Early Purchase Price applicable to such Units on the
applicable Early Purchase Date, as provided in Section 22.1(b) of the Lease and
Schedule 6A of this Participation Agreement or (y) pay a portion of such Early
Purchase Price on the applicable Early Purchase Date and the balance in
installments thereafter, on the applicable dates and in the applicable amounts
for such Basic Group as indicated on Schedule 6B; provided that Lessee may not
elect the option set forth in this clause (y) herein unless the principal amount
of the related Equipment Note applicable to such Units together with accrued
interest thereon and any applicable Make-Whole Amount shall have been paid in
respect of such Units pursuant to Section 2.10(c) of the Indenture and all other
sums due and owing to Indenture Trustee and Loan Participants under the
Operative Agreements shall have been paid in full on or prior to the Early
Purchase Date. Notwithstanding anything in this Agreement to the contrary, the
Lessee shall not be permitted to exercise any of its rights under Section 9 of
this Agreement with respect to any Units as to which the Lessee has exercised
its option set forth in clause (y) of the first paragraph of this Section 10.16.

     Lessee shall elect its payment option in the applicable notice given
pursuant to Section 22.1(b) of the Lease. If Lessee elects the option specified
in clause (y) of the first paragraph of this Section 10.16, then on the date the
initial installment is paid,

          (i)  the Lease shall be deemed terminated as to such Units and the
     Owner Trustee and the Lessee shall enter into a loan and security agreement
     in respect of the deferred Early Purchase Price in form and substance
     reasonably satisfactory to the Owner Trustee and which incorporates therein
     events of default substantially similar to those set forth in the Lease and
     covenants and terms substantially similar to those set forth in the Lease,
     and the Lessee shall deliver a legal opinion in form and substance
     reasonably satisfactory to the Owner Trustee as to the creation and
     perfection of the Owner Trustee's security interest in such Units,

         (ii)  Basic Rent in respect of such Units shall cease to accrue,

         (iii) the Owner Trustee will convey all of its right, title and
     interest in and to such Units to Lessee by delivery of a bill of sale
     without recourse or warranty except as to the absence of Lessor's Liens,
     subject, however, to the security interest of the Owner Trustee then being
     retained under the agreement referred to in clause (y) above, and

        (iv)  the Lessee shall execute such documents and take all such actions
     as Owner Trustee may reasonably request to perfect such security interest.

Upon payment by Lessee of the last such installment, the Owner Trustee shall
execute and deliver to Lessee a release of the security interest so retained.
All reasonable costs and expenses of the Owner Trustee and the Owner Participant
incurred in connection with the Lessee's election under this Section 10.16,
including, without limitation, the costs and expenses of all filings necessary
and appropriate to perfect the security interest of the Owner Trustee intended
to be established pursuant to this Section 10.16, shall be paid by the Lessee.

promptly communicate such determination in writing to Lessor and Lessee.  If
there shall be a panel of three appraisers, the three appraisals shall be
averaged and such average shall be the Fair Market Rental Value or Fair Market
Sales Value, as the case may be.  The determination made shall be conclusively
binding on both the Lessor and Lessee.  If there shall be a panel of three
appraisers, Lessee and Lessor shall equally share the cost of the third
appraiser.  If such appraisal is pursuant to Section 6.1(e) of the Lease or is

Lease, Lessee shall pay the costs of such appraisal.  Notwithstanding any of the
foregoing, for the purposes of Section 15 of the Lease, the Fair Market Rental
Value or the Fair Market Sales Value, as the case may be, shall be zero with

Units to be delivered on the Closing Date, Lessee has caused, and as soon as
practicable after the date on which a Lease Supplement is executed and delivered
in respect of a Replacement Unit pursuant to Section 11.4(b), Lessee will cause,
each Unit to be numbered with its reporting mark shown on the Lease Supplement
dated the date on which such Unit was delivered and covering such Unit, and will
from and after such date keep and maintain, plainly, distinctly, permanently and
conspicuously marked by a plate or stencil printed in contrasting colors upon
each side of each Unit, in letters not less than one inch in height, a legend
substantially as follows:

     "OWNERSHIP SUBJECT TO A SECURITY AGREEMENT FILED WITH THE SURFACE
     TRANSPORTATION BOARD"

with appropriate changes thereof and additions thereto as from time to time may
be required by law in order to protect Lessor's right, title and interest in and
to such Unit, its rights under this Lease and the rights of the Indenture
Trustee.  Except as provided hereinabove, Lessee will not place any such Units
in operation or exercise any control or dominion over the same until the
required legend shall have been so marked on both sides thereof, and will
replace promptly any such word or words in such legend which may be removed,
defaced, obliterated or destroyed. Lessee will not change the reporting mark of
any Unit except in accordance with a statement of new reporting marks to be
substituted therefor, which statement shall be delivered by Lessee to Lessor
and, so long as the Indenture shall not have been discharged pursuant to its
terms, to the Indenture Trustee prior to or contemporaneously with such change.
A supplement to this Lease and, if not so discharged, the Indenture, with
respect to such new reporting marks, shall, prior to or contemporaneously with
the substitution of such reporting marks, be filed or recorded in all public
offices where this Lease and the Indenture shall have been filed or recorded and
in such other places, if any, where Lessor and, so long as the Indenture shall
not have been discharged pursuant to its terms, the Indenture Trustee may
reasonably request in order to protect, preserve and maintain its right, title
and interest in the Units.  The costs and expenses of all such supplements,
filings and recordings shall be borne by Lessee.

          Section 4.3   Prohibition Against Certain Designations.  Except as
above provided, Lessee will not allow the name of any Person to be placed on any
Unit as a designation that might reasonably be interpreted as a claim of
ownership; provided, however, that subject to the delivery of the statement of
new reporting marks specified in Section 4.2, Lessee may cause the Equipment to
be lettered with the names or initials or other insignia customarily used by
Lessee or any permitted sublessees or any of their respective Affiliates on
railroad equipment used by it of the same or a similar type for convenience of
identification of the right of Lessee to use the Equipment hereunder or any
permitted sublessee to use the Equipment pursuant to a sublease permitted
hereby.

time to time, in the name and for the account of Lessor and Lessee, as their
interests may appear, but in all cases at the sole cost and expense of Lessee,
whatever claims and rights Lessor may have as owner of the Equipment against the
manufacturers or any prior owner thereof; provided, however, that if at any time
a Lease Event of

                                       4
<PAGE>

Default shall have occurred and be continuing, at Lessor's option, such power of
attorney shall terminate, and Lessor may assert and enforce, at Lessee's sole
cost and expense, such claims and rights. Lessor shall have no responsibility or
liability to Lessee or any other Person with respect to any of the following:
(i) any liability, loss or damage caused or alleged to be caused directly or
indirectly by any Unit, or by any of the commodities, items or materials from
time to time contained therein, whether or not permitted by the terms hereof, or
by any inadequacy thereof or deficiency or defect therein or by any other
circumstances in connection therewith; (ii) the use, operation or performance of
any Unit or any risks relating thereto; (iii) any interruption of service, loss
of business or anticipated profits or consequential damages; or (iv) the
delivery, operation, servicing, maintenance, repair, improvement or replacement
of any Unit. Lessee's delivery of a Lease Supplement shall be conclusive
evidence as between Lessee and Lessor that all Units described therein are in
all the foregoing respects satisfactory to Lessee, and Lessee will not assert
any claim of any nature whatsoever against Lessor based on any of the foregoing
matters.

     SECTION 6.  Return of Equipment; Storage.

          Section 6.1   Return; Holdover Rent.  (a) Not less than 120 days
prior to the end of the Basic Term, the end of any Fixed Rate Renewal Term, or
the end of any Fair Market Renewal Term, in each case with respect to any Units
which Lessee has elected to return under Section 22.2, Lessee will provide
Lessor with a list of alternative storage locations used for the storage of
rolling stock within the continental United States (excluding Alaska) sufficient
to store the returned Units and the available storage capacities of such
locations.  Not less than 90 days prior to the end of the Lease Term with
respect to any Unit which has not been purchased by Lessee, Lessor will give
Lessee irrevocable notice of its decision either to take possession of or store
such Unit.  If Lessor shall have decided to take possession of such Unit, the
terms of Section 6.1(b) will apply.  If Lessor shall have decided to store such
Unit, the terms of Section 6.1(c) hereof will apply.

          (b) If Lessor shall have decided to take possession of such Unit,
Lessee will, at its sole risk and expense, deliver possession of such Unit at
any track location, f.o.b. such location, (i) as may be agreed upon by Lessor
and Lessee in writing or (ii) in the absence of such agreement, as Lessor may
reasonably direct by written notice to Lessee on or before the 90th day before
the end of the Lease Term; provided, that (x) such Units shall be returned to no
more than five (5) interchange locations (each of which shall be located within
the continental United States, exclusive of Alaska), (y) there shall be no less
than 100 Units (or, if less than 100 Units are then subject to the Lease, all
Units), returned to each location, and (z) Lessor's notice shall specify the
total number and type of Units to be delivered to each location.

          (c) (i) If Lessor shall have elected to store any Unit upon the
expiration of the Lease Term with respect thereto, Lessee shall store such Unit,
free of charge for a period (the "Storage Period") beginning, for any particular
storage location, on the later of the expiration of the Lease Term and the date
on which 50% of the total number of Units being returned and stored at such
location have arrived thereat (the "Storage Period Commencement Date") and
ending not more than 45 days after the later of (A) the Storage Period
Commencement Date and (B) the date on which such Unit is in compliance with the
conditions

                                       5
<PAGE>

set forth in Section 6.2, and for an additional 60 days thereafter at the sole
risk and expense of Lessor. On or before the 90th day before the end of the
Lease Term, Lessor shall provide Lessee with written notice designating no more
than five (5) choices from among the alternative storage locations provided by
Lessee pursuant to Section 6.1(a), with a minimum of 100 Units to be stored per
location. Any storage provided by Lessee during the Storage Period (except for
such additional 60-day period referred to above) shall be at the sole risk and
expense of Lessee, and Lessee shall maintain the insurance required by Section
12.1 with respect to all stored Units; provided, however, any movement of the
Units being stored in connection with Section 6 shall be at the risk and expense
of Lessor. During the Storage Period, Lessee will permit Lessor or any Persons
designated by it, including the authorized representative or representatives of
any prospective purchaser or user of such Unit, to restencil the marks on such
Unit and to inspect the same during Lessee's normal business hours upon at least
three Business Days' prior written or telephonic notice; provided, however, that
such inspection and restenciling shall not interfere with the normal conduct of
Lessee's business; and provided, further, that (x) such inspection and
restenciling shall be at such Person's own risk, (y) Lessee shall be protected
against any loss or damage incurred by it in connection with any such inspection
or restenciling by such Person through indemnification, insurance or other means
reasonably satisfactory to Lessee and (z) Lessee (except in the case of Lessee's
gross negligence or wilful misconduct) shall not be liable for any injury to, or
the death of, any person exercising, either on behalf of Lessor or any
prospective purchaser or user, the rights of inspection and restenciling granted
pursuant hereto. Lessee shall not be required to store the Equipment after the
Storage Period. If Lessee does store any Unit after the expiration of the
Storage Period, such storage shall be at the sole risk and expense of Lessor.

               (ii) Upon the request and direction of Lessor (and at Lessor's
sole risk and expense), on not more than one occasion with respect to each
stored Unit and upon not less than 30 days' prior written notice from Lessor to
Lessee, Lessee will, on or before the expiration of the Storage Period,
transport such Units to any railroad interchange point or points within the
continental United States (except Alaska) (with a minimum of 100 Units (or, if
less than 100 Units are then subject to the Lease, all Units) per interchange
point and to a maximum of five (5) interchange points) on any railroad lines or
to any connecting carrier for shipment, whereupon Lessee shall have no further
liability or obligation with respect to such Units.

               (iii) Upon receipt of Lessor's written notice designating its
choices from among the alternative storage locations provided by Lessee under
Section 6.1(a), Lessee shall have the option to store such Units at such storage
track locations anywhere within the continental United States as it shall choose
(provided that there shall be no less than 100 Units (or, if less than 100 Units
are then subject to the Lease, all Units) stored at each such location). Upon
receipt of such notice, Lessee will promptly give notice to Lessor of the
locations at which Lessee will store such Units.  If Lessee shall exercise such
option, (x) the Storage Period shall be extended an additional 30 days and (y)
Lessee shall on or before the expiration of the Storage Period transport such
Units to any railroad interchange point within the continental United States
(except Alaska) (with a minimum of 100 Units (or, if less than 100 Units are
then subject to the Lease, all Units) per interchange point and to a maximum of
five (5) interchange points) designated by Lessor upon not less than 30 days'
prior written notice.  The movement of any Unit from such Unit's location as
designated by Lessee pursuant to this Section 6.1(c)(iii) to a location
thereafter designated by Lessor in accordance with the foregoing sentence will
be at the

                                       6
<PAGE>

risk and expense of Lessor. During any Storage Period, Lessee shall store the
Equipment in such manner as Lessee normally stores similar units of railroad
equipment owned or leased by it.

          (d) Upon the later of (i) expiration of the Lease Term with respect to
such Unit, (ii) tender of such Unit at the location determined in accordance
with Section 6.1(b) or, as applicable, the tender of such Unit for storage in
accordance with Section 6.1(c), and (iii) compliance by such Unit with Section
6.2, this Lease and the obligation to pay Basic Rent for such Unit accruing
subsequent to the expiration of the Lease Term with respect to such Unit shall
terminate.

          (e) So long as no Lease Event of Default has occurred and is
continuing, all amounts earned in respect of a Unit after the date of expiration
of the Lease Term with respect to such Unit and prior to the return of such Unit
hereunder shall belong to Lessee, and if received by Lessor, shall be promptly
turned over to Lessee.  In the event any Unit is not returned to Lessor in
accordance with the provisions of Section 6.1(b) on the last day of the Lease
Term with respect thereto, or if requested by Lessor pursuant to Section 6.1(c),
delivered and stored on such last day of the Lease Term, and, in either case, in
the condition specified in Section 6.2, Lessee shall pay to Lessor for each such
day from the expiration of the Lease Term with respect to such Unit until the
date on which such Unit is returned to Lessor in accordance with the provisions
of Section 6.1(b) and in the condition specified in Section 6.2, an amount equal
to the daily equivalent of the average Basic Rent for the Basic Term or the
Renewal Term as applicable to such Unit.  In the event Lessee is required to pay
such Rent subsequent to the expiration of the Lease Term with respect to a Unit
or Units, any amounts earned with respect to such Units shall be for the account
of Lessee.  If such Unit is not returned to Lessor in accordance with the
provisions of Section 6.1(b) and in the condition specified in Section 6.2 on or
prior to the 180th day after the expiration of the Lease Term with respect to
such Unit, Lessor shall have the right to require Lessee to purchase such Unit
for a purchase price equal to the Stipulated Loss Value for such Unit as of the
181st day after the expiration of such Lease Term; provided that if more than 25
Units have not been returned on or prior to the expiration of such Lease Term,
the purchase price for such Unit shall be the higher of (x) the Fair Market
Sales Value, assuming such Unit is in the condition required by this Lease, and
(y) the Stipulated Loss Value of such Unit as of the 181st day after the
expiration of such Lease Term; provided further that, during the holdover period
described in this sentence and the immediately preceding sentence, Lessee shall
use its best efforts to secure the return of the Equipment as required under
this Section 6 in the condition specified in Section 6.2.  Nothing herein shall
be in abrogation of Lessor's right to have such Unit returned to it for
possession or storage.  Payment of the purchase price, together with all other
amounts due and owing by Lessee under the Operative Agreements, shall be made at
the place of payment specified in Section 3.6 hereof in immediately available
funds against delivery of a bill of sale transferring and assigning to Lessee
all right, title and interest of Lessor in and to such Units on an "as-is"
"where-is" basis and containing a warranty against Lessor's Liens. Lessor shall
not be required to make any other representation or warranty as to the condition
of such Units or any other matters except as to the absence of any Lessor's
Liens, and may specifically disclaim any such representations or warranties.

          Section 6.2   Condition of Equipment.  Each Unit when returned to
Lessor pursuant to this Section 6 shall be (i) capable of performing the
functions for which it was designed, with all loading and unloading components
operating in good working order with

                                       7
<PAGE>

allowance for normal wear and tear, (ii) suitable for continued commercial use
in the commodity last carried immediately prior to such return, (iii) suitable
for use in interchange by a new owner in the operating lease business in
accordance with then applicable Federal regulations (including but not limited
to AAR and FRA), (iv) in all material respects in the condition required by
Section 8.1, (v) in conformance with any requirement pertaining to warranties of
the manufacturer of the Units during the warranty period, (vi) empty, (vii)
steam cleaned or otherwise cleaned in a comparable commercially acceptable
manner, and (viii) free and clear of all Liens except Lessor's Liens and
Permitted Liens of the type described in clause (iii) of the definition of
Permitted Liens to the extent arising as a result of a fleet wide action which
includes such Unit. All logs, records, books and other materials relating to the
maintenance of such Unit shall, upon request, be delivered to Lessor or its
designee upon the return of such Unit. Lessor shall have the right to inspect
any Unit that is returned pursuant to Section 6.1 to ensure that such Unit is in
compliance with the conditions set forth in this Section 6.2, at Lessor's sole
cost, expense and risk (including, without limitation, the risk of personal
injury or death), by its authorized representatives, during Lessee's normal
business hours and upon reasonable prior notice to Lessee; provided, however,
that Lessee shall not be liable for any injury to, or the death of, any Person
exercising, on behalf of Lessor, the rights of inspection granted under this
Section 6.2 unless caused by Lessee's gross negligence or wilful misconduct; and
further provided, that if such Unit is not in compliance with the conditions set
forth in this Section 6.2 then Lessee will (i) promptly take such steps as are
necessary to bring such Unit in compliance with the conditions set forth in this
Section 6.2 and (ii) pay the reasonable cost and expense of any reinspection of
such Unit conducted by Lessor required because of such non-compliance with
Section 6.2. No inspection pursuant to this Section 6.2 shall interfere with the
normal conduct of Lessee's business or the normal conduct of any sublessee's
business, and Lessee shall not be required to undertake or incur any additional
liabilities in connection therewith. A Unit shall not be deemed to have been
returned to Lessor for purposes of this Lease unless and until it is in
compliance with the conditions set forth in this Section 6.2.

     SECTION 7.  Liens.

          Lessee will not directly or indirectly create, incur, assume, permit
or suffer to exist any Lien on or with respect to any Unit or Lessee's leasehold
interest therein under this Lease, except Permitted Liens, Lessor's Liens and
Liens described in Section 6.4(a) and 6.4(b) of the Participation Agreement.
Lessee shall promptly, at its own expense, take such action or cause such action
to be taken as may be necessary to duly discharge (by bonding or otherwise) any
such Lien not excepted above if the same shall arise at any time.

     SECTION 8.  Maintenance; Possession; Compliance with Laws.

          Section 8.1   Maintenance and Operation.  (a)  Lessee, at its own
cost and expense, shall maintain, repair and keep each Unit, (i) according to
prudent industry practice, in good working order, and in good physical condition
for railcars of a similar age and usage, normal wear and tear excepted, (ii) in
a manner consistent with maintenance practices used by Lessee in respect of
equipment owned or leased by Lessee similar in type to such Unit, (iii) in
accordance in all material respects with all manufacturer's warranties in effect
and in accordance with all applicable provisions, if any, of insurance policies
required to be maintained pursuant to Section 12, (iv) in compliance in all
material respects with any applicable laws and regulations,

                                       8
<PAGE>

including, without limitation, the Field Manual of the AAR, FRA rules and
regulations and Interchange Rules as they apply to the maintenance and operation
of the Equipment in interchange regardless of upon whom such applicable laws and
regulations are nominally imposed and (v) in a condition mechanically suitable
for interchange by an operator in revenue service; provided, however, that
Lessee may, in good faith and by appropriate proceedings diligently conducted,
contest the validity or application of any such standard, rule or regulation in
any reasonable manner which does not materially interfere with the use,
possession, operation or return of any of the Units or materially adversely
affect the rights or interests of Lessor and the Indenture Trustee in the
Equipment or hereunder or otherwise expose Lessor, the Indenture Trustee or any
Participant to criminal sanctions or release Lessee from the obligation to
return the Equipment in compliance with the provisions of Section 6.2. Lessee
shall provide Lessor and the Indenture Trustee with notice of any contest of the
type described in the preceding sentence in detail sufficient to enable Lessor
and the Indenture Trustee to ascertain whether such contest may have an effect
of the type described in the preceding sentence. In no event shall Lessee
discriminate as to the use or maintenance of any Unit (including the periodicity
of maintenance or recordkeeping in respect of such Unit) as compared to
equipment of a similar nature which Lessee owns or leases. Lessee will maintain
all records, logs and other materials required by relevant industry standards or
any governmental authority having jurisdiction over the Units required to be
maintained in respect of any Unit, all as if Lessee were the owner of such
Units, regardless of whether any such requirements, by their terms, are
nominally imposed on Lessee, Lessor or Owner Participant.

               (b) Without the written waiver or consent of Lessor (which waiver
or consent will not be unreasonably withheld), Lessee shall not or expressly
permit any sublessee to change a DOT classification (as provided for in 49
C.F.R. Part 179 or any successor thereto), or expressly permit any sublessee to
operate any Unit under a different DOT classification, from that classification
in effect for such Unit on the Closing Date, except for any change in tank test
pressure rating provided such change does not increase the pressure rating of
the Unit above the tank test pressure to which the Unit was manufactured;
provided however, that in the event Lessor shall not have provided Lessee with a
written waiver or consent to such a reclassification or operation of any Unit
within 10 Business Days after receipt of Lessee's written request therefor (or
Lessor expressly rejects such a request by Lessee), Lessee may replace such Unit
in accordance with and subject to the provisions of Section 11.2(i), 11.3 and
11.4.

          Section 8.2   Possession.  Lessee shall be entitled to the possession
of the Equipment and to the use of the Equipment by it or any Affiliate, in the
United States and, subject to the remaining provisions of this Section 8.2 and
Section 8.3, Canada and Mexico, only in the manner for which it was designed and
intended and so as to subject it only to ordinary wear and tear.  In no event
shall Lessee make use of any Equipment in any jurisdiction not included in the
insurance coverage required by Section 12.  The Equipment shall be used
primarily on domestic routes in the United States, and in no event shall more
than thirty-five percent (35%) of the Units (as determined by mileage records)
be assigned outside the United States at the same time until after December 31,
2007.  Thereafter, no more than forty-nine percent (49%) of the Units (as
determined by mileage records) shall be used outside the continental United
States (exclusive of Alaska) at the same time.  Notwithstanding the foregoing,
no more than 15% of the Units shall be used in Mexico so long as Mexican law
does not afford protections to the Lessor comparable to U.S. law and unless
Lessee shall first have taken all

                                       9
<PAGE>

actions necessary so as to protect the right, title and interest of Lessor and
the Indenture Trustee in the Equipment in Mexico pursuant to Section 16.3 and
shall have furnished Lessor and the Indenture Trustee with an opinion of Mexican
counsel, reasonably satisfactory to such parties, to the effect that all such
filings and recordings of the related Operative Agreements have been taken and
effected under such Mexican law. Nothing in this Section 8.2 shall be deemed to
constitute permission by Lessor to any Person that acquires possession of any
Unit to take any action inconsistent with the terms and provisions of this Lease
and any of the other Operative Agreements. The rights of any Person that
acquires possession of any Unit pursuant to this Section 8.2 shall be subject
and subordinate to the rights of Lessor hereunder.

          Section 8.3   Sublease.  Provided Lessor shall not have declared the
Lease to be in default (or the Lease shall be deemed to have been declared in
default) pursuant to Section 15.1 hereof, Lessee shall be entitled, without the
prior approval of Lessor, to enter into a sublease for any Unit or Units
(pursuant to a car service contract or otherwise) to, or to grant permission for
the use thereof under car contracts by, (i) a railroad company or companies
incorporated under the laws of the United States of America or any state thereof
or the District of Columbia, Canada or any province thereof, or Mexico or any
state thereof, upon lines of railroad owned or operated by such railroad company
or companies or over which such railroad company or companies have trackage
rights or rights for operation of their trains, and upon connecting and other
carriers in the usual interchange of traffic or (ii) responsible companies
(i.e., a company with which Lessee would do business in the ordinary course of
Lessee's business with respect to railcars which it owns, leases or manages)
other than railroad companies for use in their business (leases to such
sublessees being herein referred to as "Permitted Subleases") provided, however,
that Lessee shall not sublease more than 15% of the Units to a sublessee formed
under the laws of Mexico or any state thereof.  All subleases shall include
appropriate provisions so that such subleases, (i) shall in all events be
subject and subordinate to this Lease and the rights and interests of Lessor and
its respective successors and assigns hereunder and shall confirm such
subordination by a provision substantially in the form currently contained in
Lessee's standard car service contract delivered to Lessor and the Indenture
Trustee prior to the Closing Date, or otherwise as satisfactory to Lessor and
the Indenture Trustee, (ii) shall not be for a term which extends beyond the
Basic Term and any agreed upon Renewal Term, and (iii) shall not include any
term or provision which could reasonably be expected to result in material
adverse consequences to Lessor, Owner Participant or the Indenture Trustee.  In
the event Lessee desires to sublease one or more Units for a term which extends
beyond the Basic Term or any agreed upon Renewal Term, Lessee will have the
option to replace such Unit on or prior to the expiration of the Basic Term or
any Renewal Term, with another Unit in accordance with and subject to the
provisions of Section 11.2(i), 11.3 and 11.4.  Except in connection with an
assignment pursuant to a transaction permitted by Section 6.8 of the
Participation Agreement, no sublease entered into by Lessee hereunder shall
relieve Lessee of any liability or obligation hereunder, which shall be and
remain those of a principal and not a surety.  Nothing in this Section 8.3 shall
be deemed to constitute permission to any Person in possession of any Unit
pursuant to any such sublease to take any action inconsistent with the terms and
provisions of this Lease or any of the other Operative Agreements.

                                       10

     SECTION 9.  Modifications.

          Section 9.1   Required Modifications.  In the event the AAR, the
United States Department of Transportation, or any other United States or state
governmental agency or any other applicable law requires that any Unit be
altered, replaced or modified (a "Required Modification"), Lessee agrees to make
such Required Modification at its own expense; provided, however, that Lessee
may, in good faith and by appropriate proceedings diligently conducted, contest
the validity or application of any such law, regulation, requirement or rule in
any reasonable manner which does not materially interfere with the use,
possession, operation or return of any Unit or materially adversely affect the
rights or interests of Lessor and the Indenture Trustee in the Equipment or
hereunder or otherwise expose Lessor, the Indenture Trustee or any Participant
to criminal sanctions or relieve Lessee of the obligation to return the
Equipment in compliance with the provisions of Section 6.2.  Title to any
Required Modification shall immediately vest in Lessor.  Notwithstanding
anything herein to the contrary, if Lessee determines in good faith that any
Required Modification to a Unit would be economically impractical, in lieu of
making the Required Modification as provided above, Lessee may provide written
notice of such determination to Lessor and treat such Unit as if an Event of
Loss had occurred as of the date of such written notice with respect to such
Unit and in such event the provisions of Sections 11.2, 11.3 and 11.4 shall
apply with respect to such Unit; provided that Lessee shall not discriminate
against such Unit in making such determination of economic impracticality as
compared with other equipment of the same type as such Unit which is owned or
leased by Lessee.

          Section 9.2   Optional Modifications.  Lessee at any time may in its
discretion and at its own cost and expense modify, alter or improve any Unit in
a manner which is not required by Section 9.1 (a "Modification"); provided that
no Modification shall diminish the fair market value, utility, capacity, or
remaining economic useful life of such Unit below the fair market value,
utility, capacity, or remaining economic useful life thereof immediately prior
to such Modification, in any non de minimus respect, assuming such Unit was then
in the condition required to be maintained by the terms of this Lease, provided
that Lessee shall not discriminate against such Unit in making such
modification, alteration or improvement as compared with other equipment of the
same type as the Unit and which are owned or leased by the Lessee.  Title to any
Non-Severable Modification shall be immediately vested in Lessor.  Title to any
Severable Modification (other than Required Modifications) shall remain with
Lessee.  If Lessee shall at its cost cause such Severable Modifications (other
than Required Modifications) to be made to any Unit, Lessor shall have the
right, upon 90 days prior written notice in the case of a return other than
pursuant to Section 15.6, prior to the return of such Unit to Lessor hereunder,
to purchase such Severable Modifications (other than Severable Modifications
consisting of proprietary or communications equipment) at their then Fair Market
Sales Value (taking into account their actual condition).  If Lessor does not so
elect to purchase such Severable Modifications, Lessee may remove such Severable
Modifications at Lessee's cost and expense, and if requested (which request
shall be made by not less than 90 days prior written notice in the case of a
return other than pursuant to Section 15.6) by Lessor will so remove such
Severable Modifications at Lessee's cost and expense, and Lessee shall, at its
expense, repair any damage resulting from the removal of any such Severable
Modifications in a manner consistent with Section 8.1.

                                       11
<PAGE>

          Section 9.3   Removal of Property; Replacements.  Lessee may, in the
ordinary course of maintenance or repair of any Unit, remove any item of
property constituting a part of such Unit, and unless the removal of such item
is required by Section 9.1 hereof, Lessee shall replace such item as promptly as
practicable by an item of property that is free and clear of all Liens (other
than Permitted Liens) and in as good operating condition as, and with a fair
market value, utility, capacity and remaining economic useful life at least
equal to, the item of property being replaced, assuming that such replaced item
was in the condition required to be maintained by the terms of this Lease.  Any
item of property removed from such Unit in the ordinary course of maintenance
and repair as provided in the preceding sentence shall remain the property of
Lessor free and clear of all rights of Lessee until replaced in accordance with
the terms of such sentence, but shall then, without further act, become the
property of Lessee.  Any such property replaced in the ordinary course of
maintenance and repair shall, without further act, become the property of Lessor
and be deemed part of such Unit for all purposes hereof.

     SECTION 10.  Voluntary Termination.

          Section 10.1   Right of Termination.  So long as no Material Default
or Lease Event of Default shall have occurred and be continuing, Lessee shall
have the right, at its option at any time or from time to time during the Basic
Term on or after the seventh anniversary of the Basic Term Commencement Date to
terminate the Lease Term with respect to any or all of the Units (provided that,
if such termination is for less than all Units in a Basic Group, Lessee shall
exercise such termination with respect to at least 25 Units, no fewer than 25
Units shall remain in such Basic Group as a result of such termination and the
determination as to which Units are subject to termination shall be made by
Lessee on a random or other basis (in each case reasonably acceptable to Lessor)
without discrimination based on maintenance status, operating condition of the
Units in question or otherwise) (the "Terminated Units") if Lessee determines in
good faith (as evidenced by a certified copy of a resolution adopted by Lessee's
Board of Directors and a certificate executed by the Chief Financial Officer of
Lessee) that such Units have become obsolete or surplus to Lessee's requirements
by delivering at least 120 days' prior notice to Lessor and the Indenture
Trustee (i) specifying a proposed date of termination for such Units (the
"Termination Date"), which date shall, except as provided in the last sentence
of Section 10.3, be a Rent Payment Date, any such termination to be effective on
the Termination Date upon Lessee's compliance with this Section 10, and (ii) if
some but less than all of the Units in a Basic Group are designated as
Terminated Units, describing the nondiscriminatory manner in which Lessee
proposes to determine which Units in that Basic Group are to be Terminated
Units. Except as expressly provided herein, there will be no conditions to
Lessee's right to terminate this Lease with respect to the Terminated Units
pursuant to this Section 10.1.  So long as (a) Lessor shall not have given
Lessee a notice of election to retain the Terminated Units in accordance with
Section 10.3, or (b) notice of prepayment of the Equipment Notes shall not have
been given pursuant to Section 2.10 of the Indenture, Lessee may withdraw the
termination notice referred to above at any time prior to the Termination Date,
whereupon this Lease shall continue in full force and effect; provided that
Lessee (i) may not exercise its right to withdraw such a termination notice more
than once annually or more than four times during the Basic Term, and (ii) may
not withdraw any termination notice with respect to any Terminated Units after
receipt by Lessee of a bid equal to or greater than Termination Value with
respect to such Terminated Units or later than sixty (60) days prior to the
scheduled Termination Date.  Lessee agrees that if it withdraws a termination
notice it will reimburse Lessor, Owner Participant and

                                       12
<PAGE>

the Indenture Trustee for all reasonable out-of-pocket costs and expenses
(including reasonable legal fees and expenses) incurred by any thereof in
connection therewith.

          Section 10.2   Sale of Equipment.  During the period from the date of
such notice given pursuant to Section 10.1 to the Termination Date, Lessee, as
agent for Lessor and, except as provided in Section 10.3, at Lessee's sole cost
and expense, shall use reasonable best efforts to obtain bids from Persons other
than Lessee or Affiliates thereof for the cash purchase of the Terminated Units,
and Lessee shall promptly, and in any event at least five Business Days prior to
the proposed date of sale, certify to Lessor in writing the amount and terms of
each such bid, the proposed date of such sale and the name and address of the
party submitting such bid.  Unless Lessor shall have elected to retain the
Terminated Units in accordance with Section 10.3, on the Termination Date:  (i)
Lessee shall, subject to the prior or concurrent receipt (x) by Lessor of all
amounts owing to Lessor pursuant to the next sentence, and (y) by the Persons
entitled thereto of all unpaid Supplemental Rent due on or before the
Termination Date, deliver the Terminated Units (excluding any optional Severable
Modifications removed by Lessee pursuant to Section 9.2) to the bidder (which
shall not be Lessee or any Affiliate thereof), if any, which shall have
submitted the highest cash bid prior to such date (or to such other bidder as
Lessee and Lessor shall agree) and (ii) Lessor shall, without recourse or
warranty (except as to the absence of any Lessor's Lien) simultaneously
therewith transfer all of its right, title and interest in and to the Terminated
Units to such bidder. The net proceeds of sale realized at such sale shall be
paid to and retained by Lessor and, in addition, on the Termination Date, Lessee
shall pay to Lessor, (A) all unpaid Rent with respect to such Terminated Units
due and payable on or prior to the Termination Date (exclusive of any Basic Rent
first becoming due on such date), (B) the excess, if any, of (1) the Termination
Value for the Terminated Units computed as of the Termination Date, over (2) the
net cash sales proceeds (after the deduction of all reasonable costs and
expenses of Lessor and Owner Participant in connection with such sale) of the
Terminated Units, and (C) an amount equal to the Make-Whole Amount, if any, in
respect of the principal amount of the Equipment Notes to be prepaid in
accordance with Section 2.10(a) of the Indenture; provided however, in the event
that the net cash proceeds with respect to such Units referred to above exceed
the Termination Value for such Units, Lessee shall receive a credit against
amounts payable to Lessor pursuant to this Section 10.2 in an amount equal to
the lesser of (I) the Prepaid Adjustment Amount, if any, and (II) the amount by
which such net cash proceeds exceed the Termination Value for such Units any (y)
Lessee shall pay to Lessor an amount equal to the Deferred Adjustment Amount, if
any. If no sale shall have occurred, whether as a result of Lessee's failure to
pay all of the amounts hereinabove required or otherwise, this Lease shall
continue in full force and effect with respect to such Units and Lessee agrees
to reimburse Lessor, Owner Participant and the Indenture Trustee for all
reasonable costs and expenses (including reasonable legal fees and expenses)
incurred by any thereof in connection therewith; provided that if such sale
shall not have occurred solely because of Lessee's failure to pay the amounts
hereinabove required, Lessee shall have no further right to terminate this Lease
with respect to such Units. Lessee, in acting as agent for Lessor, shall have no
liability to Lessor for failure to obtain the best price, shall act in its sole
discretion and shall be under no duty to solicit bids publicly or in any
particular market. Lessee's sole interest in acting as agent shall be to use its
reasonable best efforts to sell the Units at the highest price then obtainable
consistent with the terms of this Lease.

          Section 10.3   Retention of Equipment by Lessor.  Notwithstanding the
provisions of Sections 10.1 and 10.2, Lessor may irrevocably elect by written
notice to Lessee,

                                       13
<PAGE>

no later than 60 days after receipt of Lessee's notice of termination, not to
sell the Terminated Units on the Termination Date, whereupon Lessee shall (i)
deliver the Terminated Units to Lessor in the same manner and condition as if
delivery were made to Lessor pursuant to Section 6.1(b) and Section 6.2,
treating the Termination Date as the termination date of the Lease Term with
respect to the Terminated Units, and (ii) pay to Lessor, or to the Persons
entitled thereto, all Rent due and owing on the Termination Date and unpaid
(exclusive of any in advance Basic Rent due on such date but inclusive of any
Supplemental Rent measured by the Make-Whole Amount). If Lessor elects not to
sell the Terminated Units as provided in this Section 10.3, then Lessor shall
pay, or cause to be paid, to the Indenture Trustee in funds of the type and in
an amount equal to the outstanding principal amount of the Equipment Notes
issued in respect of such Terminated Units and all accrued and unpaid interest
to the date of prepayment of such Equipment Notes on such Termination Date and
an amount equal to the Make-Whole Amount, if any, in respect of the principal
amount of the Equipment Notes to be prepaid without in any manner relieving the
Lessee of its obligation to pay any such amount pursuant to the preceding
sentence; provided that unless Lessor shall have paid all such amounts to the
Indenture Trustee on the Termination Date, this Lease shall continue in full
force and effect. If Lessor shall fail to pay the amounts required pursuant to
this Section 10.3 and as a result thereof this Lease shall not be terminated
with respect to the Terminated Units on a proposed Termination Date, Lessor
shall (x) thereafter no longer be entitled to exercise its election to retain
such Terminated Units, and (y) reimburse Lessee for any reasonable out-of-pocket
expenses (including reasonable legal fees and expenses) incurred by it in
attempting to sell the Terminated Units pursuant to Section 10.2 immediately
prior to Lessor's exercise of such preemptive election, and Lessee may at its
option at any time thereafter prior to the immediately following Rent Payment
Date submit a new termination notice pursuant to Section 10.1 with respect to
such Terminated Units specifying a proposed Termination Date occurring on a
Determination Date occurring not earlier than 25 days from the date of such
notice.

          Section 10.4   Termination of Lease.  In the event of either (x) any
such sale and receipt by Lessor and the Indenture Trustee of all of the amounts
provided in Section 10.2 or (y) retention of the Equipment and full performance
by Lessor of its payment obligations in compliance with Section 10.3, and upon
compliance by Lessee with the other provisions of this Section 10, the
obligation of Lessee to pay Basic Rent hereunder for such Terminated Units shall
cease and the Lease Term for the Terminated Units shall end.

     SECTION 11.  Loss, Destruction, Requisition, Etc.

          Section 11.1   Event of Loss.  In the event that any Unit (i) shall
suffer damage or contamination which, in Lessee's reasonable judgment (as
evidenced by an Officers' Certificate to such effect), makes repair uneconomic
or renders such Unit unfit for commercial use, (ii) shall suffer destruction, or
shall suffer theft or disappearance (after reasonable efforts by Lessee to
locate the same) for a period exceeding 12 months (or, if earlier, the end of
the Basic Term or Renewal Term then in effect), (iii) shall be permanently
returned to the manufacturer pursuant to any patent indemnity provisions, (iv)
shall have title thereto taken or appropriated by any governmental authority,
agency or instrumentality under the power of eminent domain or otherwise, (v)
shall be taken or requisitioned for use by (x) any governmental authority of
Mexico or any agency or instrumentality thereof under the power of eminent
domain or otherwise for a period in excess of the lesser of (A) 365 days and (B)
the remaining Basic Term

                                       14
<PAGE>

or any Renewal Term then in effect or (y) any other governmental agency or
instrumentality thereof under the power of eminent domain or otherwise for a
period in excess of the remaining Basic Term or any Renewal Term then in effect
(unless such taking or requisition is by any governmental authority, agency or
instrumentality other than the United States or Canada in which case such period
shall be the lesser of the period as aforesaid or 365 days) (any such occurrence
being hereinafter called an "Event of Loss"), Lessee, in accordance with the
terms of Section 11.2, shall promptly and fully inform Lessor and the Indenture
Trustee of such Event of Loss.

          Section 11.2   Replacement or Payment upon Event of Loss.  Upon the
occurrence of (a) an Event of Loss or the deemed occurrence of an Event of Loss
pursuant to Section 9.1 or (b) an election to replace pursuant to Section 8.1(b)
or 8.3, with respect to any Unit, Lessee shall as soon as reasonably practical
and in any event within 60 days after a Responsible Officer of Lessee shall have
actual knowledge of such occurrence or election give Lessor and the Indenture
Trustee notice of such occurrence of such Event of Loss or election to replace
(which notice shall identify the Unit involved) and then within the 60-day
period following such notice give Lessor and the Indenture Trustee notice as to
which of the following options Lessee shall elect to perform (it being agreed
that if Lessee shall fail to give notice of such election, Lessee shall be
deemed to have elected to perform the option set forth in Section 11.2(ii)):

                    (i) Upon Lessee's election to perform under this clause (i),
     as promptly as practicable following such election, and in any event on or
     before the 60th day following the date of notice of such Event of Loss or
     deemed Event of Loss pursuant to Section 9.1, or the date Lessee exercises
     an option to replace pursuant to Section 8.1(b) or Section 8.3, as the case
     may be, Lessee shall comply with Section 11.4(b) and shall convey or cause
     to be conveyed to Lessor a Replacement Unit to be leased to Lessee
     hereunder, such Replacement Unit to be of the same car type of the same or
     newer model year (or otherwise approved by Lessor, which approval shall not
     be unreasonably withheld), and free and clear of all Liens (other than
     Permitted Liens of the type described in clause (ii) with respect to
     sublessees, and in clauses (iii), (iv), (vi) and (vii) of the definition
     thereof) and to have a fair market value, utility, capacity, remaining
     economic useful life and condition at least equal to the Unit so replaced
     (assuming such Unit was in the condition required to be maintained by the
     terms of this Lease); provided that, if, at the time of such replacement,
     only railcars (x) of a newer model year or (y) with a greater fair market
     value (or a greater Fair Market Sales Value in the situation set forth in
     the next proviso) than the replaced Units are available as Replacement
     Units, Lessee shall convey such Replacement Unit to Lessor as set forth
     above but Lessee may, at a later date, replace such Replacement Units with
     other Units that are closer in fair market value (or Fair Market Sales
     Value in the situation set forth in the next proviso) to the original
     replaced Units so long as such replacement does not result in any
     additional unindemnified tax liability; provided further that, if such
     replacement is performed (a) pursuant to Section 8.3 after the 180th day
     prior to the end of the Lease Term of such Units or (b) with respect to 15
     or more Units, each of such Replacement Units must have, in addition to the
     requirements set forth above, a Fair Market Sales Value at least equal to
     the Unit so replaced (assuming such Unit was in the condition required to
     be maintained by the terms of this Lease); provided further that, if Lessee
     shall elect the option under

                                      15
<PAGE>

     this clause (i) within such period but shall fail to perform its obligation
     to effect such replacement under this paragraph (i) within the 60-day
     period hereinabove provided for, then (except in the case of a failure to
     perform an election to replace pursuant to Section 8.1(b) or Section 8.3)
     at the end of such 60-day period Lessee shall immediately give Lessor and
     the Indenture Trustee notice of such failure and specify that Lessee shall
     pay to Lessor on the next succeeding Rent Payment Date that is at least 25
     days after the end of such 60-day period, or in the case of Supplemental
     Rent, to the Person entitled thereto, the amounts specified in paragraph
     (ii) below as of such next succeeding Rent Payment Date, and Lessee shall
     pay such amounts on such Rent Payment Date; provided further that Lessee
     shall have no right to elect replacement under this clause (i) if at the
     time of the notice of the Event of Loss under Section 11.2 above a Material
     Default or Lease Event of Default shall have occurred and be continuing; or

                    (ii) on the Rent Payment Date which is not less than 25 days
     following the date of notice of Lessee's election to perform under this
     clause (ii), Lessee shall pay or cause to be paid to Lessor (or in the case
     of Supplemental Rent, to the Persons entitled thereto) in funds of the type
     specified in Section 3.6, (a) an amount equal to the Stipulated Loss Value
     of each such Unit suffering an Event of Loss or deemed Event of Loss
     determined as of such Rent Payment Date, (b) all Basic Rent payable on such
     date in respect of such Unit (exclusive of any Basic Rent first becoming
     due on such date) [and an amount equal to the Adjustment Amount (which
     amount, if negative, shall be a credit against amounts payable by Lessee
     pursuant to this Section 11.2(ii))], and (c) all other Rent then due and
     payable hereunder, it being understood that until such Stipulated Loss
     Value and other sums are paid, there shall be no abatement or reduction of
     Basic Rent;

provided that in the event at any time a Responsible Officer of Lessee shall
have actual knowledge of the occurrence or deemed occurrence of an Event of Loss
with respect to an aggregate of 15 or more Units as to which Lessee would
otherwise be obligated to make payment pursuant to the second proviso to
paragraph (i) above or pursuant to paragraph (ii) above on a Rent Payment Date,
then Lessee shall thereupon give Lessor and the Indenture Trustee notice that in
lieu of making payments with respect to such Units as otherwise above provided
on a Rent Payment Date, Lessee will make a payment with respect to such Units on
the next succeeding Determination Date which is at least 25 days after such
notice, and on such Determination Date Lessee shall pay, in lieu of the amounts
otherwise required to be paid in respect of such Units on a Rent Payment Date as
provided above, (a) an amount equal to the Stipulated Loss Value of such Units
determined as of such Determination Date, (b) if such Determination Date is also
a Rent Payment Date, all Basic Rent payable on such date in respect of such
Units (exclusive of any in advance Basic Rent due on such date) and (c) all
other Rent then due and payable hereunder, it being understood that until such
Stipulated Loss Value and other sums are paid, there shall be no abatement or
reduction of Basic Rent.

          Section 11.3   Rent Termination.  Upon the replacement of any Unit or
Units in compliance with Sections 11.2(i) and 11.4(b) (but only as to replaced
Units and not any Replacement Unit) or upon the payment of all sums required to
be paid pursuant to Section 11.2 in respect of any Unit or Units, the Lease Term
with respect to such Unit or Units and the obligation to pay Basic Rent for such
Unit or Units accruing subsequent to the date of payment

                                       16
<PAGE>

of Stipulated Loss Value or date of conveyance of such Replacement Unit or Units
pursuant to Section 11.2 shall terminate; provided that Lessee shall be
obligated to pay all Rent in respect of such Unit or Units which is payable
under Section 11.2 with respect to such payment of Stipulated Loss Value or such
replacement of such Unit or Units and in respect of all other Units then
continuing to remain subject to this Lease.

          Section 11.4   Disposition of Equipment; Replacement of Unit.    (a)
Upon the payment of all sums required to be paid pursuant to Section 11.2 in
respect of any Unit or Units, Lessor will convey to Lessee or its designee all
right, title and interest of Lessor in and to such Unit or Units, "as is",
"where is", without recourse or warranty, except for a warranty against Lessor's
Liens, and shall execute and deliver to Lessee or its designee such bills of
sale and other documents and instruments as Lessee or its designee may
reasonably request to evidence such conveyance.  As to each separate Unit so
disposed of, so long as no Lease Event of Default shall have occurred and be
continuing, Lessee or its designee shall be entitled to any amounts arising from
such disposition, plus any awards, insurance or other proceeds and damages
received by Lessee, Lessor or the Indenture Trustee by reason of such Event of
Loss after having paid the Stipulated Loss Value and any other Rent attributable
thereto.

               (b) At the time of or prior to any replacement of any Unit or
Replacement Unit, Lessee, at its own expense, will (A) furnish Lessor with a
Bill of Sale with respect to the Replacement Unit substantially in the form
delivered pursuant to Section 4.1(g) of the Participation Agreement, (B) cause a
Lease Supplement substantially in the form of Exhibit A hereto, subjecting such
Replacement Unit to this Lease, and duly executed by Lessee, to be delivered to
Lessor for execution and, upon such execution, to be filed for recordation in
the same manner as provided for the original Lease Supplement in Section 16.1,
(C) so long as the Indenture shall not have been satisfied and discharged, cause
an Indenture Supplement substantially in the form of Exhibit A to the Indenture
for such Replacement Unit, to be delivered to Lessor and to the Indenture
Trustee for execution and, upon such execution, to be filed for recordation in
the same manner and within the same time periods as provided for the original
Indenture Supplement in Section 16.1, (D) furnish Lessor with an opinion of
Lessee's counsel (which may be Lessee's General Counsel or Assistant General
Counsel), (x) to the effect that the Bill of Sale referred to in clause (A)
above constitutes an effective instrument for the conveyance of title to the
Replacement Unit to Lessor, and that legal and beneficial title to the
Replacement Unit has been delivered to Lessor, free and clear of all Liens
(other than Permitted Liens of the type described in clause (ii) with respect to
sublessees, and in clauses (iii), (iv), (vi) and (vii) of the definition
thereof), and (y)  describing all filings and recordings and other actions
necessary or appropriate to protect the respective interests of Lessor and the
Indenture Trustee in the Replacement Units, (E) furnish Owner Participant with
either (I) an opinion of tax counsel (who shall be, and which opinion shall be
in form and substance reasonably acceptable to the Owner Participant) that the
Owner Participant will not suffer any adverse tax consequences as a result of
such substitution, or (II) an agreement to indemnify Owner Participant against
any adverse tax consequences suffered as a result of such replacement, (F)
furnish Lessor with an engineer's certificate (which may be from an employee of
Lessee) certifying as to the utility, capacity, condition, model year and
remaining useful life required under clause (i) of Section 11.2, (G) furnish to
Lessor and the Indenture Trustee an Officer's Certificate certifying that the
Replacement Unit has a fair market value, utility, capacity, model year and
remaining economic useful life and condition at least equal to the Unit being
replaced and is free and clear of all Liens

                                       17
<PAGE>

(other than Permitted Liens of the type described in clause (ii) with respect to
sublessees, and in clauses (iii), (iv), (vi) and (vii) of the definition
thereof), and (H) furnish such other documents and evidence as Owner
Participant, Lessor or the Indenture Trustee, or their respective counsel, may
reasonably request in order to establish the consummation of the transactions
contemplated by this Section 11.4. For all purposes hereof, (i) Lessee shall be
deemed to have complied with the requirements of this Section 11.4(b) as of the
date of its delivery to Lessor, the Participants and the Indenture Trustee of
the documents and instruments referred to in the foregoing clauses (A) through
(H), signed by Lessee or its counsel, as applicable, in due form for any
required filing or recording, and such filing or recording shall have been made
if such documents and instruments have been executed and delivered by the Lessor
or Indenture Trustee or both of them in a timely manner, (ii) title to the
Replacement Unit shall be deemed to have been transferred to Lessor as of such
date, and (iii) upon such passage of title thereto to Lessor the Replacement
Unit shall be deemed part of the property leased hereunder and the Replacement
Unit shall be deemed a "Unit" of Equipment as defined herein. Upon such passage
of title, Lessor will transfer to Lessee, "as is" and "where is" and without
recourse or warranty (except as to Lessor's Liens), all Lessor's right, title
and interest in and to the replaced Unit, and upon such transfer, Lessor will
request in writing that the Indenture Trustee execute and deliver to Lessee an
appropriate instrument releasing such replaced Unit from the lien of the
Indenture. Lessee shall pay all reasonable out of pocket costs and expenses
(including reasonable legal fees and expenses) incurred by Lessor, Owner
Participant and the Indenture Trustee in connection with any replacement
pursuant to this Section 11.4.

          Section 11.5   Eminent Domain.  In the event that during the Lease
Term the use of any Unit is requisitioned or taken by any governmental authority
under the power of eminent domain or otherwise for a period which does not
constitute an Event of Loss, all of Lessee's obligations under the Operative
Agreements, including without limitation, Lessee's obligation to pay all
installments of Basic Rent, shall continue for the duration of such
requisitioning or taking. Lessee shall be entitled to receive and retain for its
own account all sums payable for any such period by such governmental authority
as compensation for requisition or taking of possession. Any amount referred to
in this Section 11.5, in Section 11.4(a) or in Section 12 which is payable to
Lessee shall not be paid to Lessee, or if it has been previously paid directly
to Lessee, shall not be retained by Lessee, if at the time of such payment a
Lease Default under Section 14(g) or Section 14(h) or a Lease Event of Default
shall have occurred and be continuing, but shall be paid to and held by Lessor
pursuant to Section 24, or if the Indenture shall not then have been discharged
pursuant to its terms, to the Indenture Trustee, as security for the obligations
of Lessee under this Lease, and at such time as there shall not be continuing
any such Lease Default or Lease Event of Default, such amount shall be paid to
Lessee.

     SECTION 12.  Insurance.

          Section 12.1   Insurance.  Lessee will at all times after delivery and
acceptance of each Unit, at its own expense, keep or cause to be kept such Unit
insured by a reputable insurance company or companies in amounts and against
risks and with deductibles and terms and conditions not less than the insurance,
if any, maintained by Lessee with respect to similar equipment which it owns or
leases, but in no event shall such coverage be for amounts or against risks less
than the prudent industry standard for companies engaged in full service leasing
of railcars.  Without limiting the foregoing, Lessee will in any event:

                                       18
<PAGE>

               (a) keep each Unit of the Equipment insured against physical
damage in an amount not less than the Stipulated Loss Value attributable thereto
as shown on Schedule 4 to the Participation Agreement, subject to a limit of not
less than $10 million per occurrence (except for a $10 million annual aggregate
each for flood and earth movement), provided that such coverage may provide for
deductible amounts of not more than $1,000,000 per occurrence; and

               (b) maintain public liability insurance naming Owner Participant,
the Lessor, the Trust Company and the Indenture Trustee as additional insureds
(but only with respect to liability arising out of or related to the Operative
Agreements and the Equipment) against bodily injury, death or property damage
arising out of the use or operation of the Equipment with general and excess
liability limits of not less than $50,000,000 per occurrence or in the
aggregate, provided that such coverage may provide for deductible amounts not
exceeding the lesser of (x) $10,000,000 or (y) 5% of the book value of the
railcar fleet of Lessee.

          It is understood and agreed that the insurance required hereunder may
be part of a company-wide insurance program, including risk-retention and self-
insurance.  Any policy of insurance maintained in accordance with this Section
12.1 and any policy purchased in substitution or replacement for any of such
policies shall provide that if any such insurance is cancelled or terminated for
any reason whatever (other than upon normal policy expiration), Lessor,
Indenture Trustee and Owner Participant shall receive 30 days' prior written
notice of such cancellation or termination.

          Section 12.2   Physical Damage Insurance.  (a)  The insurance
maintained pursuant to Section 12.1(a) shall provide that (i) so long as the
Equipment Notes remain outstanding, the proceeds up to the Stipulated Loss
Value, for any loss or damage to any Unit shall be made to the Indenture Trustee
under a standard loss payable clause, and thereafter to Lessor and (ii) so long
as no Lease Event of Default shall have occurred and be continuing, Lessee will
be entitled, at its own expense, to make all proofs of loss and take all other
steps necessary to collect the proceeds of such insurance.

               (b) In lieu of maintaining the physical damage insurance required
by Section 12.1(a), Lessee may self-insure with respect to the Equipment for
such amounts and against such risks as shall be consented to by Lessor and the
Indenture Trustee, which consent shall be based upon reasonable practices then
in effect in the railcar leasing and insurance industries and upon the financial
condition of Lessee.

               (c) The entire proceeds of any property insurance or third party
payments for damages to any Unit received by Lessor or the Indenture Trustee
shall be held by such party until, with respect to such Unit, the repairs
referred to in clause (i) below are made as specified therein or payment of the
Stipulated Loss Value is made, and such entire proceeds will be paid, so long as
no Lease Event of Default shall have occurred and be continuing, either:

                                       19
<PAGE>

                    (i) to Lessee promptly following receipt by the Indenture
     Trustee or Lessor, as the case may be, of a written application signed by
     Lessee for payment to Lessee for repairing or restoring the Units which
     have been damaged so long as (1) Lessee shall have complied with the
     applicable provisions of the Lease, and (2) Lessee shall have certified
     that any damage to such Units shall have been fully repaired or restored;
     or

                    (ii) if this Lease is terminated with respect to such Unit
     because of an Event of Loss and Lessee has paid the Stipulated Loss Value
     due as a result thereof, such proceeds shall be promptly paid over to, or
     retained by, Lessee.

          Section 12.3   Public Liability Insurance.  (a)  The public liability
insurance referred to in paragraph 12.1(b) shall (i) provide that in as much as
such policies cover more than one insured, all terms, conditions, insuring
agreements and endorsements, with the exception of limits of liability and
liability for premiums, commissions, assessments or calls (which shall be solely
a liability of Lessee), shall operate in the same manner as if there were a
separate policy or policies covering each insured, (ii) waive any rights of
subrogation of the insurers against Owner Participant, Lessor, the Trust Company
and the Indenture Trustee, (iii) provide that none of Owner Participant, Lessor,
the Trust Company, or Indenture Trustee shall have any responsibility for any
insurance premiums, whether for coverage before or after cancellation or
termination of any such policies as to Lessee and (iv) be primary without
contribution from any similar insurance maintained by Owner Participant, Lessor
or the Indenture Trustee.

               (b) Lessee shall use its reasonable efforts to obtain public
liability insurance policies stipulating that coverage thereunder will not be
invalidated (as to Owner Participant, Lessor, the Trust Company and the
Indenture Trustee) due to any action or inaction of Lessee or any other Person
(other than Owner Participant, Lessor or the Indenture Trustee, but only in
respect of their respective coverages), but shall be under no obligation to
obtain such policies containing such stipulations if they are not available to
Lessee at commercially reasonable rates in the markets in which Lessee has then
placed its insurance program.

               (c) In the event any public liability insurance policy or
coverage thereunder which is required to be maintained under Section 12.1(b)
shall not be available to Lessee in the commercial insurance market on
commercially reasonable terms, Lessor shall not unreasonably withhold its
agreement to waive such requirement. Lessee shall make written request for any
such waiver in writing, accompanied by written reports prepared, at Lessee's
option, either by (i) one independent insurance advisor chosen by Lessee and
Lessor or (ii) three independent insurance advisors, one chosen by Lessor, one
chosen by Lessee and one chosen by the other two advisors (one of which may be
the regular insurance broker of Lessee), in either case, such independent
insurance advisors being of recognized national standing. The fees and expenses
of all such advisors shall be paid by Lessee. The written reports required
hereunder shall (x) state that such insurance (or the required coverage
thereunder) is not reasonably available to Lessee at commercially reasonable
premiums in the commercial insurance markets within which Lessee normally
purchases its insurance from insurers, acceptable to Lessee, with a Best's
rating of A- or better for railcars of similar type and capacity and (y) explain
in detail the basis for such conclusions. Upon the granting of any such waiver,
Lessee shall within 15 days thereafter certify to Lessor in writing the cost (on
a fleet-wide basis) of liability insurance

                                       20
<PAGE>

premiums for the coverage required by Section 12.1(b) for the immediately
preceding fiscal year; and in the event that any such certificate is not
received by Lessor within such 15 day period, any such waiver shall be deemed
revoked. At any time after the granting of such waiver, but not more often than
once a year, Lessor may make a written request for a supplemental report (in
form reasonably acceptable to Lessor) from such insurance advisor(s) updating
the prior report and reaffirming the conclusions set forth therein. Lessee shall
provide any such required supplemental report within 60 days after receipt of
the written request therefor. Any such waiver shall be effective for only as
long as such insurance is not reasonably available to Lessee in the commercial
markets in which Lessee normally purchases its insurance at commercially
reasonable rates, it being understood that the failure of Lessee to furnish
timely any such supplemental report shall be conclusive evidence that such
condition no longer exists. If such supplemental report shows that such coverage
is available, Lessee shall within 90 days of such report obtain such insurance
coverage. During any period with respect to which such waiver has been granted
and remains in effect under this Section 12.3(c), Lessee shall obtain public
liability insurance as set forth in Section 12.1(b) from such carriers, in such
amounts and with coverage limits and deductibles as is prudent under the
circumstances, but in any event in an amount that may be purchased for a premium
equal to 110% of Lessee's cost (on a fleet-wide basis) of public liability
insurance premiums for the coverage required by Section 12.1(b) for the fiscal
year immediately preceding the fiscal year in which such waiver first was
granted.

          Section 12.4   Certificate of Insurance.  Lessee shall, prior to the
Closing Date and when the renewal certificate referred to below is sent (but in
any event not less than annually), furnish Lessor, the Indenture Trustee and the
Owner Participant with a certificate signed by the insurer or an independent
insurance broker showing the insurance then maintained by Lessee pursuant to
this Section.  With respect to any renewal policy or policies, certificates or
binders evidencing such renewal shall be furnished as soon as practicable, but
in no event later than 30 days after the earlier of the date such renewal is
effected or the expiration date of the original policy or policies.
Simultaneously, with the furnishing of such certificate, Lessee will provide
appropriate evidence, reasonably satisfactory to Lessor and the Indenture
Trustee, that all premiums due on such insurance have been paid.

          Section 12.5   Additional Insurance.  In the event that Lessee shall
fail to maintain insurance as herein provided, in Section 12.1 or, if
applicable, Section 12.3, Lessor may at its option, upon prior written notice to
Lessee, provide such insurance and, in such event, Lessee shall, upon demand
from time to time, reimburse Lessor for the cost thereof together with interest
from the date of payment thereof at the Late Rate, on the amount of the cost to
Lessor of such insurance which Lessee shall have failed to maintain.  If after
Lessor has provided such insurance, Lessee then obtains the coverage provided
for in Section 12.1 which was replaced by the insurance provided by Lessor, and
Lessee provides Lessor with evidence of such coverage reasonably satisfactory to
Lessor, Lessor shall cancel the insurance it has provided pursuant to the first
sentence of this Section 12.5.  In such event, Lessee shall reimburse Lessor for
all costs to Lessor of cancellation, including without limitation any short rate
penalty, together with interest from the date of Lessor's payment thereof at the
Late Rate.  In addition, at any time Lessor (either directly or in the name of
Owner Participant) may at its own expense carry insurance with respect to its
interest in the Units, provided that such insurance does not interfere with
Lessee's ability to insure the Equipment as required by this Section 12 or
adversely affect Lessee's insurance or the cost thereof, it being understood
that all salvage rights to each Unit

                                       21
<PAGE>

shall remain with Lessee's insurers at all times. Any insurance payments
received from policies maintained by Lessor pursuant to the previous sentence
shall be retained by Lessor without reducing or otherwise affecting Lessee's
obligations hereunder, other than with respect to Unit(s) with respect to which
such payments have been made.

     SECTION 13.  Reports; Inspection.

          Section 13.1   Duty of Lessee to Furnish.  On or before April 30,
2001, and on or before each April 30 thereafter, Lessee will furnish to Lessor,
Owner Participant and the Indenture Trustee an accurate statement, as of the
preceding December 31, (a) showing the amount, description and reporting marks
of the Units then leased hereunder, the amount, description and reporting marks
of all Units that may have suffered an Event of Loss during the 12 months ending
on such December 31 (or since the Closing Date, in the case of the first such
statement), and such other information regarding the condition or repair of the
Equipment as Lessor may reasonably request, (b) stating that, in the case of all
Equipment repainted during the period covered by such statement, the markings
required by Section 4.2 hereof shall have been preserved or replaced, (c)
showing the percentage of use in each state in the United States and in both
Canada and Mexico based on the total mileage traveled by all railcars in
Lessee's fleet (or by the Units, if and to the extent generally made available
to Lessee in the ordinary course with respect to railcars in general interchange
service similar to the Units) for the prior calendar year as reported to Lessee
by railroads (provided, that Lessee shall cooperate with Owner Participant and
Lessor and shall provide such additional information on such matters as Owner
Participant or Lessor may reasonably request to enable Owner Participant and
Lessor to pursue or fulfill their respective tax audit and tax litigation rights
and obligations), and (d) stating that Lessee is not aware of any condition of
any Unit which would cause such Unit not to comply in any material respect with
the rules and regulations of the FRA and the interchange rules of the Field
Manual of the AAR as they apply to the maintenance and operation of the
Equipment in interchange.

          Section 13.2   Lessor's Inspection Rights.  Lessor, Owner Participant
and the Indenture Trustee each shall have the right, but not the obligation, at
their respective sole cost, expense and risk (including, without limitation, the
risk of bodily injury or death), by their respective authorized representatives,
to inspect (a) the Equipment and Lessee's records with respect thereto, and (b)
following the occurrence of a Lease Default and during the continuance thereof,
or following notice by Lessee that it will be returning any Unit to Lessor
pursuant to Section 10 or Section 22, any sublease of the Equipment and Lessee's
records with respect thereto.  All inspections shall be conducted during
Lessee's normal business hours, on Lessee's premises or in areas that are not
the premises of a sublessee to which Lessee has reasonable access, and upon
reasonable prior notice to Lessee.  Lessee shall not be liable for any injury
to, or the death of, any Person exercising, either on behalf of Lessor, any
Owner Participant, the Indenture Trustee or any prospective user, the rights of
inspection granted under this Section 13.2 unless caused by Lessee's gross
negligence or wilful misconduct.  No inspection pursuant to this Section 13.2
shall interfere with the use, operation or maintenance of the Equipment or the
ordinary course of Lessee's or any sublessee's business, and Lessee shall not be
required to undertake or incur any additional liabilities in connection
therewith.

                                       22

     SECTION 14.  Lease Events of Default.

          The following events shall constitute Lease Events of Default
hereunder (whether any such event shall be voluntary or involuntary or come
about or be effected by operation of law or pursuant to or in compliance with
any judgment, decree or order of any court or any order, rule or regulation of
any administrative or governmental body) and each such Lease Event of Default
shall be deemed to exist and continue so long as, but only as long as, it shall
not have been remedied:

               (a) Lessee shall fail to make any payment of Basic Rent, Special
Purchase Price, Early Purchase Price, Basic Term Purchase Price or any other
purchase price to be paid by Lessee for any Units pursuant to this Lease or the
Participation Agreement, Stipulated Loss Value or Termination Value within 10
Business Days after the same shall have become due; or

               (b) Lessee shall fail to make any payment of Supplemental Rent,
including indemnity or tax indemnity payments, but not including Stipulated Loss
Value, Special Purchase Price, Early Purchase Price, Basic Term Purchase Price
or any other purchase price to be paid by Lessee for any Units pursuant to this
Lease or the Participation Agreement after the same shall have become due and
such failure shall continue unremedied for 10 Business Days after receipt by
Lessee of written notice of such failure from Lessor, Owner Participant or the
Indenture Trustee; or

               (c) Lessee shall fail to maintain in effect the insurance
required by Section 12 and such failure shall not have been waived as provided
for therein; or

               (d) Lessee shall make or permit any possession of the Equipment
or any portion thereof not permitted by this Lease, provided that such
unauthorized possession shall not constitute a Lease Event of Default for a
period of 45 days after the occurrence thereof so long as (i) such unauthorized
possession is not the result of any willful action of Lessee and (ii) such
unauthorized possession is capable of being cured and Lessee diligently pursues
such cure throughout such 45-day period; or Lessee shall make or permit any
unauthorized assignment or transfer of this Lease in violation of Section 18.2;
or

               (e) Lessee shall fail to observe or perform any of the covenants
or agreements to be observed or performed by Lessee in Section 6.8 of the
Participation Agreement, and such failure shall continue unremedied for 30 days
during which period Lessee diligently pursues the cure of such failure; or

               (f) any representation or warranty made by Lessee in any Lessee
Agreement (other than the Tax Indemnity Agreement) is untrue or incorrect in any
material respect as of the date of making thereof and such untruth or
incorrectness shall continue to be material and unremedied for a period of 30
days after receipt by Lessee of written notice thereof from Lessor, Owner
Participant or the Indenture Trustee; provided that, if such untruth or
incorrectness is capable of being remedied, no such untruth or incorrectness
shall constitute a Lease Event of Default hereunder for a period of 60 days
after receipt of such notice so long as Lessee is diligently proceeding to
remedy such untruth or incorrectness and shall in fact remedy

                                       23
<PAGE>

such untruth or incorrectness within such period; provided that such untrue or
incorrect representation or warranty shall be deemed to be remedied only after
all adverse consequences thereof, if any, have been remedied; or

               (g) Lessee 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

               (h) an involuntary case or other proceeding shall be commenced
against Lessee seeking liquidation, reorganization or other relief with respect
to it 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, and such involuntary case or other proceeding shall remain
undismissed and unstayed for a period of 60 days; or

               (i) Lessee shall fail to observe or perform any other of the
covenants or agreements to be observed or performed by Lessee under any Lessee
Agreement (other than the Tax Indemnity Agreement) or any certificate and such
failure shall continue unremedied for 30 days after notice from Lessor, Owner
Participant or the Indenture Trustee to Lessee, specifying the failure and
demanding the same to be remedied; provided that, if such failure is capable of
being remedied, and the remedy requires an action other than, or in addition to,
the payment of money, no such failure (other than one relating to the payment of
such money) shall constitute a Lease Event of Default hereunder for a period of
90 days after receipt of such notice so long as Lessee is diligently proceeding
to remedy such failure and shall in fact remedy such failure within such period;

provided that, notwithstanding anything to the contrary contained in this Lease,
any failure of Lessee to perform or observe any covenant or agreement herein
shall not constitute a Lease Event of Default if such failure is caused solely
by reason of an event referred to in the definition of "Event of Loss" so long
as Lessee is continuing to comply with the applicable terms of Section 11.

     SECTION 15.  Remedies.

          Section 15.1   Remedies.  Upon the occurrence of any Lease Event of
Default and at any time thereafter so long as the same shall be continuing,
Lessor may, at its option, declare this Lease to be in default by a written
notice to Lessee (except that this Lease shall, without any action on the part
of Lessor, be automatically deemed to have been declared in default upon the
occurrence of a Lease Event of Default described in Section 14(g) or (h)); and
at any time thereafter, unless Lessee shall have remedied all outstanding Lease
Events of Default prior to the commencement of the exercise by Lessor of any of
its remedies hereunder, Lessor may do one or

                                       24
<PAGE>

more of the following as Lessor in its sole discretion shall elect, to the
extent permitted by, and subject to compliance with any mandatory requirements
of, applicable law then in effect:

               (a) proceed by appropriate court action or actions, either at law
or in equity, to enforce performance by Lessee of the applicable covenants of
this Lease or to recover damages for the breach thereof;

               (b) by notice in writing to Lessee, Lessor may demand that
Lessee, and Lessee shall, upon written demand of Lessor and at Lessee's expense,
forthwith return all or any part of the Equipment to Lessor or its order in the
manner and condition required by, and otherwise in accordance with all of the
provisions of Section 15.6; or Lessor with or without notice or judicial process
may by its agents enter upon the premises of Lessee or other premises where any
of the Equipment may be located and take possession of and remove all or any of
the Units, and Lessor may use and employ in connection with such removal any
services, aids, equipment, trackage and other facilities of Lessee as is
reasonably required to remove such Units and thenceforth hold, possess and enjoy
the same free from any right of Lessee, or its successor or assigns, to use such
Units for any purpose whatever;

               (c) sell any Unit at public or private sale in such manner as
Lessor may determine, free and clear of any rights of Lessee and without any
duty to account to Lessee with respect to such sale or for the proceeds thereof
(except to the extent required by paragraph (f) below if Lessor elects to
exercise its rights under said paragraph), in which event Lessee's obligation to
pay Basic Rent with respect to such Unit hereunder due for any periods
subsequent to the date of such sale shall terminate (except to the extent that
Basic Rent is to be included in computations under paragraph (e) or (f) below if
Lessor elects to exercise its rights under either of said paragraphs);

               (d) hold, keep idle or lease to others any Unit as Lessor in its
sole discretion may determine, free and clear of any rights of Lessee and
without any duty to account to Lessee with respect to such action or inaction or
for any proceeds with respect thereto, except that Lessee's obligation to pay
Basic Rent with respect to such Unit due for any periods subsequent to the date
upon which Lessee shall have been deprived of possession and use of such Unit
pursuant to this Section 15 shall be reduced by the net proceeds, if any,
received by Lessor from leasing such Unit to any Person other than Lessee;

               (e) whether or not Lessor shall have exercised, or shall
thereafter at any time exercise, any of its rights under paragraph (a), (b), (c)
or (d) above with respect to any Unit, Lessor, by written notice to Lessee
specifying a payment date (which date shall be a Determination Date for the
purposes of computing Stipulated Loss Value) which shall be not less than 30
days after the date of such notice, may demand that Lessee pay to Lessor, and
Lessee shall pay to Lessor, on the payment date specified in such notice, as
liquidated damages for loss of a bargain and not as a penalty (in lieu of the
Basic Rent for such Unit due after the payment date specified in such notice),
all Rent due and payable, or accrued, for such Unit as of the payment date
specified in such notice (exclusive of any Basic Rent first becoming due on such
date) plus whichever of the following amounts Lessor, in its sole discretion,
shall specify in such notice: (i) an amount with respect to each such Unit which
represents the excess of the present value, at the time of such payment date, of
all rentals for such Unit which would otherwise have

                                       25
<PAGE>

accrued hereunder from such payment date for the remainder of the Basic Term or
any Renewal Term then in effect over the then present value of the then Fair
Market Rental Value of such Unit (taking into account its actual condition) for
such period computed by discounting from the end of such Term to such payment
date rentals which Lessor reasonably estimates to be obtainable for the use of
such Unit during such period, such present value to be computed in each case on
a basis of a per annum discount at the Debt Rate, compounded semiannually from
the respective dates upon which rentals would have been payable hereunder had
this Lease not been terminated plus an amount equal to the Deferred Adjustment
Amount, if any, provided, however, the Prepaid Adjustment Amount, if any, shall
be a credit against amounts payable by Lessee pursuant to this Section
15.1(e)(i); or (ii) an amount equal to the excess, if any, of the Stipulated
Loss Value for such Unit computed as of the payment date specified in such
notice over the Fair Market Sales Value of such Unit (taking into account its
actual condition) as of the payment date specified in such notice; or (iii) if
Lessor shall not have sold such Unit pursuant to the exercise of its rights
under paragraph (c) above with respect to such Unit, an amount equal to the
higher of Stipulated Loss Value for such Unit computed as of the payment date
specified in such notice or the Fair Market Sales Value of such Unit (assuming
it is in the condition required by this Lease) as of the payment date specified
in such notice, provided, however, in the event that the Fair Market Sales Value
with respect to such Unit referred to above exceeds Termination Value for such
Unit, then (a) Lessee shall receive a credit against amounts payable to Lessor
pursuant to this Section 15.1(e)(iii) in an amount equal to the lesser of (I)
the Prepaid Adjustment Amount, if any, and (II) the amount that such Fair Market
Sales Value exceeds the Termination Value for such Unit and (b) Lessee shall pay
to Lessor an amount equal to the Deferred Adjustment Amount, if any; and upon
payment by Lessee pursuant to said clause (iii) of such Stipulated Loss Value or
Fair Market Sales Value, as the case may be, and of all other amounts payable by
Lessee under this Lease and under the other Operative Agreements in respect of
such Unit, Lessor shall transfer "as is" and "where is" and without recourse or
warranty all right, title and interest of Lessor in and to such Unit to Lessee
or as it may direct, and Lessor shall execute and deliver such documents
evidencing such transfer as Lessee shall reasonably request;

               (f) if Lessor shall have sold any Unit pursuant to paragraph (c)
above, Lessor, in lieu of exercising its rights under paragraph (e) above with
respect to such Unit may, if it shall so elect, demand that Lessee pay to
Lessor, and Lessee shall pay to Lessor, as liquidated damages for loss of a
bargain and not as a penalty (in lieu of the Basic Rent for such Unit due
subsequent to the Rent Payment Date next preceding such sale), any accrued and
unpaid Rent for such Unit as of the date of such sale (Basic Rent for this
purpose accruing at a per diem rate equal to the semiannual amount due on the
next following Rent Payment Date divided by 180), plus the amount, if any, by
which the Stipulated Loss Value of such Unit computed as of the Rent Payment
Date next preceding the date of such sale or, if such sale occurs on a Rent
Payment Date, then computed as of such Rent Payment Date, exceeds the net
proceeds of such sale, plus interest on such amounts from the date of such sale
to the date of payment at the Late Rate; and

                                      26
<PAGE>

               (g) Lessor may terminate the leasing of any or all Units under
this Lease or may exercise any other right or remedy that may be available to it
under applicable law.

          In addition, Lessee shall be liable, except as otherwise provided
above, for any and all unpaid Rent due hereunder before or during the exercise
of any of the foregoing remedies (exclusive of any in advance Basic Rent due on
such date), and for legal fees and other costs and expenses incurred by reason
of the occurrence of any Lease Event of Default or the exercise of Lessor's
remedies with respect thereto, including without limitation the repayment in
full of any costs and expenses necessary to be expended in repairing any Unit in
order to cause it to be in compliance with all maintenance and regulatory
standards imposed by this Lease.

          Section 15.2   Cumulative Remedies.  The remedies in this Lease
provided in favor of Lessor shall not be deemed exclusive, but shall be
cumulative and shall be in addition to all other remedies in its favor existing
at law or in equity.  Lessee hereby waives any mandatory requirements of law,
now or hereafter in effect, which might limit or modify any of the remedies
herein provided, to the extent that such waiver is permitted by law.  Lessee
hereby waives any and all existing or future claims of any right to assert any
offset or counterclaim against the Rent payments due hereunder, and agrees to
make the rent payments regardless of any offset or counterclaim or claim which
may be asserted by Lessee on its behalf in connection with the lease of the
Equipment.  Lessee further agrees that Lessee's obligations to pay all Rent
(including, without limitation, all Basic Rent and Supplemental Rent) and its
obligations to maintain the Equipment pursuant to Section 8 hereof and to
maintain the insurance pursuant to Section 12 hereof shall constitute monetary
obligations of the Lessee for all purposes of Section 365 of the Bankruptcy
Code.  To the extent permitted by applicable law, Lessee hereby waives any
rights now or hereafter conferred by statute or otherwise that may require
Lessor to sell, lease or otherwise use the Equipment in mitigation of Lessor's
damages as set forth in Section 15.1 or that may otherwise limit or modify any
of Lessor's rights and remedies provided in this Section 15.

          Section 15.3   No Waiver.  No delay or omission to exercise any right,
power or remedy accruing to Lessor upon any breach or default by Lessee under
this Lease shall impair any such right, power or remedy of Lessor, nor shall any
such delay or omission be construed as a waiver of any breach or default, or of
any similar breach or default hereafter occurring; nor shall any waiver of a
single breach or default be deemed a waiver of any subsequent breach or default.

          Section 15.4   Notice of Lease Default.  Lessee agrees to furnish to
Lessor, Owner Participant and the Indenture Trustee, promptly upon any officer
acquiring actual knowledge of any condition which constituted or constitutes a
Lease Default under this Lease, written notice specifying such condition and the
nature and status thereof.

          Section 15.5   Lessee's Duty to Furnish Information with Respect to
Subleases. Upon the declaration of a Lease Event of Default pursuant to Section
14(a), (b), (d) (with respect to the Units affected thereby), (g) or (h), Lessor
may request that Lessee deliver to Lessor, and

                                       27
<PAGE>

upon such request Lessee agrees that it will promptly provide to Lessor, a
detailed list of all Units that are then being subleased by Lessee, the identity
of the sublessees with respect to such Units, the identity of an employee or
other agent of each such sublessee with whom Lessee regularly communicates with
in respect of such Units and the most recent known location of such Units.

          Section 15.6   Lessee's Duty to Return Equipment Upon Default.  If
Lessor or any assignee of Lessor shall terminate this Lease pursuant to this
Section 15 and shall have provided to Lessee the written demand specified in
Section 15.1(b), Lessee shall forthwith deliver possession of the Equipment to
Lessor (except where Lessor has received all amounts payable by Lessee pursuant
to any notice provided by Lessor under Section 15.1(e)(iii)).  For the purpose
of delivering possession of any Unit to Lessor as above required, Lessee shall
at its own cost, expense and risk (except as hereinafter stated):

               (a) Forthwith place such Equipment upon such storage tracks of
Lessee or any of its affiliates or, at the expense of Lessee, on any other
storage tracks, as Lessor may designate or, in the absence of such designation,
as Lessee may select;

               (b) Permit Lessor to store such Equipment on such tracks without
charge for insurance, rent or storage until such Equipment has been sold, leased
or otherwise disposed of by Lessor and during such period of storage Lessee
shall continue to maintain all insurance required by Section 12.1 hereof; and

               (c) Transport the Equipment to any place on any lines of railroad
or to any connection carrier for shipment, all as Lessor may direct in writing.

All Equipment returned shall be in the condition required by Section 6.2 hereof.

          All amounts earned in respect of the Equipment after the date of
termination of this Lease pursuant to this Section 15, but not exceeding amounts
actually received therefor, shall be paid to Lessor or, so long as the Indenture
shall not have been discharged pursuant to its terms, the Indenture Trustee,
and, if received by Lessee, shall be promptly turned over to Lessor or the
Indenture Trustee as aforesaid.  In the event any Unit is not assembled,
delivered and stored as hereinabove provided within 15 days after the
termination of the leasing of such Unit pursuant to Section 15, Lessee shall, in
addition, pay to Lessor or the Indenture Trustee as aforesaid as liquidated
damages and not as a penalty, for each day thereafter an amount equal to the
amount, if any, by which the higher of (i) an amount equal to 110% of the daily
equivalent of the Basic Rent in effect immediately prior to the expiration of
the Lease for such Unit and (ii) 125% of the Fair Market Rental Value for such
Unit (determined upon the assumption that such Unit is in the condition required
by the terms of this Lease) for each such day exceeds the amount, if any,
received by Lessor or the Indenture Trustee as aforesaid (either directly or
from Lessee) for such day for such Unit pursuant to the preceding sentence.

          Section 15.7   Specific Performance; Lessor Appointed Lessee's Agent.
The assembling, delivery, storage and transporting of the Equipment as provided
in Section 15.6 are of the essence of this Lease, and upon application to any
court of equity having jurisdiction in the premises, Lessor shall be entitled to
a decree against Lessee requiring specific performance of the

covenants of Lessee so to assemble, deliver, store and transport the Equipment.
Without in any way limiting the obligation of Lessee under the provisions of
Section 15.6, Lessee hereby irrevocably appoints Lessor as the agent and
attorney of Lessee, with full power and authority, at any time while Lessee is
obligated to deliver possession of any Units to Lessor pursuant to this Section
15, to demand and take possession of such Unit in the name and on behalf of
Lessee from whosoever shall be at the time in possession of such Unit.

     SECTION 16.  Filings; Further Assurances.

          Section 16.1   Filings.  This Lease or a counterpart or copy hereof
or evidence hereof may be filed or recorded in any public office as may be
necessary or appropriate to protect the interest of Lessor, Owner Participant or
the Indenture Trustee herein or in the Units.  On or prior to the Closing Date
Lessee will cause this Lease, the Lease Supplements dated the Closing Date, the
Indenture and the Indenture Supplements dated the Closing Date (i) to be duly
filed and recorded with the STB in accordance with 49 U.S.C. (S)11301, (ii) to
be deposited with the Registrar General of Canada pursuant to Section 105 of the
Canada Transportation Act (and all necessary actions shall have been taken for
publication of such deposit in The Canada Gazette in accordance with said
Section 105) and (iii) will furnish Lessor, the Indenture Trustee and Owner
Participant proof thereof.

          Section 16.2   Further Assurances.  Lessee will duly execute and
deliver to Lessor such further documents and assurances and take such further
action as Lessor may from time to time reasonably request or as may be required
by applicable law or regulation in order to effectively carry out the intent and
purpose of this Lease and to establish and protect the rights and remedies
created or intended to be created in favor of Lessor, Owner Participant and the
Indenture Trustee hereunder, including, without limitation, the execution and
delivery of supplements or amendments hereto, in recordable form, subjecting to
this Lease any Replacement Unit and the recording or filing of counterparts
hereof or thereof in accordance with the laws of such jurisdiction as Lessor may
from time to time deem advisable.

          Section 16.3   Other Filings.  If, at any time during the Lease Term,
Mexico, or one or more states in Mexico, or any of the Canadian provinces
establishes a state or provincial or other system for filing and perfecting the
security and/or ownership interests of entities such as Lessor and/or the
Indenture Trustee, at the time that Lessee takes such action with respect to
other equipment similar to the Equipment (whether owned or leased by Lessee) and
also upon the request of Lessor, at the direction of the Owner Participant, or
the Indenture Trustee, Lessee 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 under such system to
be effected and taken, in order to perfect and protect the respective right,
title and interests of Lessor, Owner Participant and the Indenture Trustee.

          Section 16.4   Expenses.  Lessee will pay all costs, charges and
expenses (including reasonable attorneys fees) incident to any such filing,
refiling, recording and rerecording or depositing and re-depositing of any such
instruments or incident to the taking of such action.

     SECTION 17.  Lessor's Right to Perform.  If Lessee fails to make any
payment required to be made by it hereunder or fails to perform or comply with
any of its other agreements contained herein, Lessor may itself make such
payment or perform or comply with such agreement, after giving not less than
five Business Days' prior notice thereof to Lessee (except in the event that an
Indenture Default resulting from a Lease Default or a Lease Event of Default
shall have occurred and be continuing, in which event Lessor may effect such
payment, performance or compliance to the extent necessary to cure such
Indenture Default with notice given concurrently with such payment, performance
or compliance), but shall not be obligated hereunder to do so, and the amount of
such payment and of the reasonable expenses of Lessor incurred in connection
with such payment or the performance of or compliance with such agreement, as
the case may be, together with interest thereon at the Late Rate from such date
of payment, to the extent permitted by applicable law, shall be deemed to be
Supplemental Rent, payable by Lessee to Lessor on demand.

     SECTION 18.  Assignment.

          Section 18.1   Assignment by Lessor.  Lessee and Lessor hereby confirm
that concurrently with the execution and delivery of this Lease, Lessor has
executed and delivered to the Indenture Trustee the Indenture, which assigns as
collateral security and grants a security interest in favor of the Indenture
Trustee in, to and under this Lease and certain of the Rent payable hereunder
(excluding Excepted Property), all as more explicitly set forth in the
Indenture. Lessor agrees that it shall not otherwise assign or convey its right,
title and interest in and to this Lease, the Equipment or any Unit, except as
expressly permitted by and subject to the provisions of the Participation
Agreement, the Trust Agreement and the Indenture.

          Section 18.2   Assignment by Lessee.  Except as otherwise provided in
Section 8.3 or in the case of any requisition for use by any governmental
authority or any agency or instrumentality thereof referred to in Section 11.1,
Lessee will not, without the prior written consent of Lessor and the Indenture
Trustee (which consent shall not be unreasonably withheld), assign any of its
rights hereunder, except as provided herein and in the Participation Agreement;
provided that Lessee may assign its rights and/or obligations hereunder to any
corporation in accordance with the provisions of Section 6.8 of the
Participation Agreement or to any corporation which is an Affiliate of Lessee,
provided that in the case of an assignment to an Affiliate, (a) Lessor shall
have received an instrument or instruments reasonably satisfactory to it, Owner
Participant and the Indenture Trustee under which such Affiliate assumes the
obligations of Lessee hereunder, and (b) Lessee irrevocably and unconditionally
guarantees, pursuant to an agreement in form and substance reasonably
satisfactory to Lessor, Owner Participant and the Indenture Trustee, such
assignee's performance of all of such obligations as primary obligor and not as
a surety.

          Section 18.3   Sublessee's Performance and Rights.  Any obligation
imposed on Lessee in this Lease shall require only that Lessee perform or cause
to be performed such obligation, even if stated herein as a direct obligation,
and the performance of any such obligation by any permitted assignee, sublessee
or transferee under an assignment, sublease or transfer agreement then in effect
and permitted by the terms of this Lease shall constitute performance by Lessee
and discharge such obligation by Lessee.  Except as otherwise expressly provided
herein, any right granted to Lessee in this Lease shall grant Lessee the right
to

                                       30
<PAGE>

(a) exercise such right or permit such right to be exercised by any such
assignee or transferee, or (b) in Lessee's capacity as sublessor pursuant to any
sublease permitted pursuant to Section 8.3 hereof, permit any sublessee to
exercise substantially equivalent rights under any such sublease as are granted
to Lessee under this Lease; provided, however, that Lessee's right to terminate
this Lease pursuant to Section 10 and Lessee's purchase and renewal options set
forth in Section 22 may be exercised only by Lessee itself or by any assignee or
transferee of, or successor to, Lessee in a transaction permitted by Section 6.8
of the Participation Agreement; provided, further, that nothing in this Section
18.3 shall or shall be deemed to (i) create any privity of contract between any
such sublessee, on the one hand, and any of Lessor, any Owner Participant or any
subsequent transferee or Affiliate of any such Person, on the other hand, (ii)
create any duty or other liability of any nature whatsoever on the part of any
of Lessor, any Owner Participant or any subsequent transferee or Affiliate of
any such Person, to any such sublessee or any Affiliate thereof, or (iii) modify
or waive any term or provision of Section 8.3 hereof, which Section 8.3 shall
control if any conflict arises between any of the provisions thereof and this
Section 18.3.  The inclusion of specific references to obligations or rights of
any such assignee, sublessee or transferee in certain provisions of this Lease
shall not in any way prevent or diminish the application of the provisions of
the two sentences immediately preceding with respect to obligations or rights in
respect of which specific reference to any such assignee, sublessee or
transferee has not been made in this Lease.

     SECTION 19.  Net Lease, etc.  This Lease is a net lease and Lessee's
obligation to pay all Rent payable hereunder shall be absolute, unconditional
and irrevocable and shall not be affected by any circumstance of any character
including, without limitation, (i) any set-off, abatement, counterclaim,
suspension, recoupment, reduction, rescission, defense or other right that
Lessee may have against Lessor, Owner Participant, the Indenture Trustee or any
holder of an Equipment Note or Pass Through Certificate, any vendor or
manufacturer of any Unit, or any other Person for any reason whatsoever, (ii)
any defect in or failure of title, merchantability, condition, design,
compliance with specifications, operation or fitness for use of all or any part
of any Unit, (iii) any damage to, or removal, abandonment, requisition, taking,
condemnation, loss, theft or destruction of all or any part of any Unit or any
interference, interruption, restriction, curtailment or cessation in the use or
possession of any Unit by Lessee or any other Person for any reason whatsoever
or of whatever duration, (iv) any insolvency, bankruptcy, reorganization or
similar proceeding by or against Lessee, Lessor, Owner Participant, the
Indenture Trustee, any holder of an Equipment Note or Pass Through Certificate
or any other Person, (v) the invalidity, illegality or unenforceability of this
Lease, any other Operative Agreement, or any other instrument referred to herein
or therein or any other infirmity herein or therein or any lack of right, power
or authority of Lessee, Lessor, Owner Participant, the Indenture Trustee, any
holder of an Equipment Note or Pass Through Certificate or any other Person to
enter into this Lease or any other Operative Agreement or to perform the
obligations hereunder or thereunder or consummate the transactions contemplated
hereby or thereby or any doctrine of force majeure, impossibility, frustration
or failure of consideration, (vi) the breach or failure of any warranty or
representation made in this Lease or any other Operative Agreement by Lessee,
Lessor, Owner Participant, the Indenture Trustee, any holder of an Equipment
Note or Pass Through Certificate or any other Person, (vii) the requisitioning,
seizure or other taking of title to or use of such Unit by any government or
governmental authority or otherwise, whether or not by reason of any act or
omission of Lessor, Lessee or the Indenture Trustee, or any other deprivation or
limitation of use of such Unit in any respect or for any length of time, whether
or not resulting from accident

                                       31
<PAGE>

and whether or not without fault on the part of Lessee, or (viii) any other
circumstance or happening whatsoever, whether or not similar to any of the
foregoing. To the extent permitted by applicable law, Lessee hereby waives any
and all rights which it may now have or which at any time hereafter may be
conferred upon it, by statute or otherwise, to terminate, cancel, quit or
surrender this Lease with respect to any Unit, except in accordance with the
express terms hereof. If for any reason whatsoever this Lease shall be
terminated in whole or in part by operation of law or otherwise, except as
specifically provided herein, Lessee nonetheless agrees, to the maximum extent
permitted by law, to pay to Lessor or to the Indenture Trustee, as the case may
be, an amount equal to each installment of Basic Rent and all Supplemental Rent
due and owing, at the time such payment would have become due and payable in
accordance with the terms hereof had this Lease not been terminated in whole or
in part. Each payment of Rent made by Lessee hereunder shall be final and Lessee
shall not seek or have any right to recover all or any part of such payment from
Lessor or any Person for any reason whatsoever. Nothing contained herein shall
be construed to waive any claim which Lessee might have under any of the
Operative Agreements or otherwise or to limit the right of Lessee to make any
claim it might have against Lessor or any other Person or to pursue such claim
in such manner as Lessee shall deem appropriate.

     SECTION 20.  Notices.  Unless otherwise expressly specified or permitted by
the terms hereof, all communications and notices provided for herein shall be in
writing or by facsimile capable of creating a written record, and any such
notice shall become effective (i) upon personal delivery thereof, including,
without limitation, by overnight mail or courier service, (ii) in the case of

     SECTION 21.  Concerning the Indenture Trustee.

          Section 21.1   Limitation of the Indenture Trustee's Liabilities.
Notwithstanding any provision herein or in any of the Operative Agreements to
the contrary, the Indenture Trustee's obligation to take or refrain from taking
any actions, or to use its discretion (including, but not limited to, the giving
or withholding of consent or approval and the exercise of any rights or remedies
under such Operative Agreements), and any liability therefor, shall, in addition
to any other limitations provided herein or in the other Operative Agreements,
be limited by the provisions of the Indenture, including, but not limited to,
Article VI thereof.

          Section 21.2   Right, Title and Interest of the Indenture Trustee
Under Lease.  It is understood and agreed that the right, title and interest of
the Indenture Trustee in, to and under this Lease and the Rent due and to become
due hereunder shall by the express terms granting and conveying the same be
subject to the interest of Lessee in and to the Equipment.

     SECTION 22.  Purchase Options; Renewal Options.

          Section 22.1   (a)  Special Purchase Option.  Provided that no
Material Default or Lease Event of Default shall have occurred and be continuing
at the time of the notice described below or on the date of the proposed
purchase of Units pursuant to the terms of this Section 22.1(a) (unless (i)
Lessor shall have waived such Material Default or Lease Event of Default

                                       33
<PAGE>

solely for the purpose of this Section 22.1(a), (ii) in the case of a Lease
Event of Default under Section 14(c), 14(d), 14(e), 14(f) or 14(i), Lessee shall
have properly made a Special Purchase Defeasance after giving effect to the
purchase described below, no such Lease Event of Default shall be continuing, or
(iii) in the event of a Lease Event of Default under Section 14(g) or 14(h),
Lessee shall have obtained a final, nonappealable order of a United States court
having appropriate bankruptcy jurisdiction over Lessee which (x) authorizes such
purchase and (y) is in form and substance satisfactory to Lessor and Indenture
Trustee) and provided that Lessee shall have duly given the notice required by
the next succeeding sentence, Lessee shall have the right and, upon giving of
such notice, the obligation to purchase any or all of the Units then leased
hereunder (as specified in such notice) on the Special Purchase Date at a price
equal to the greater of the then applicable Termination Value for such Units and
the then current Fair Market Sales Value for such Units as determined in
accordance with Section 22.5 (the "Special Purchase Price"), provided that after
giving effect to such purchase (unless Lessee shall have elected to purchase all
of the Units then leased hereunder), (i) no fewer than 425 Units shall remain
subject to the Lease, (ii) the allocation of Units (by Basic Group) shall be
substantially similar to the allocation immediately prior to such purchase and
(iii) no Basic Group shall have less than 25 Units, and provided further that
the determination as to which Units are to be purchased shall be made on a
random or other basis (in each case reasonably acceptable to Lessor) without
discrimination based on maintenance status, operating condition of the Units in
question or otherwise and such notice shall describe such manner in which Lessee
proposes to determine the Units in such Basic Group which will be purchased.
Lessee shall give Lessor written notice not less than 90 days prior to the
Special Purchase Date of the proposed purchase of Units pursuant to the terms of
this Section 22.1(a), which notice shall be irrevocable. On the Special Purchase
Date, Lessee shall pay the Special Purchase Price, together with all other
amounts due and owing by Lessee under the Operative Agreements with respect to
such Units, including, without limitation, all unpaid Rent therefor due and
payable on or prior to such purchase date (exclusive of any Basic Rent first
becoming due on such date) and, in the event that the Fair Market Sales Value
with respect to such Units referred to above exceeds the Termination Value for
such Units, then (a) Lessee shall receive credit against amounts payable to
Lessor pursuant to this Section 22.1(a), in an amount equal to the lessor of (I)
the Prepaid Adjustment, if any, and (II) the amount that such Fair Market Sales
Value exceeds the Termination Value for such Units and (b) Lessee shall pay to
Lessor an amount equal to the Deferred Adjustment Amount, if any. Such payments
shall be made at the place of payment specified in Section 3.6 hereof in
immediately available funds against delivery of a bill of sale transferring and
assigning to Lessee all right, title and interest of Lessor in and to such Units
on an "as-is" "where-is" basis and containing a warranty against Lessor's Liens.
Lessor shall not be required to make any other representation or warranty as to
the condition of such Units or any other matters, and may specifically disclaim
any such representations or warranties. In the event of any such purchase and
receipt by Lessor of all the amounts provided in this Section 22.1(a), the
obligation of Lessee to pay Basic Rent hereunder for such Units shall cease and
the Lease Term for such Units shall end.

               (b) Early Purchase Option. Provided that no Material Default or
Lease Event of Default shall have occurred and be continuing either at the time
of the notice described below or on the Early Purchase Date (unless (i) Lessor
shall have waived such Lease Event of Default or Lease Default solely for the
purpose of this Section 22.1(b), (ii) in the case of a Lease Event of Default
under Section 14(c), 14(d), 14(e), 14(f) or 14(i), Lessee shall have properly
made a Special Purchase Defeasance and after giving effect to the purchase
described below, no such Lease Event of Default shall be continuing or (iii) in
the case of a Lease Event of Default under Section 14(g) or 14(h), Lessee shall
have obtained a final, nonappealable order of a United States court having
appropriate bankruptcy jurisdiction over Lessee which (x) authorizes such

                                       34
<PAGE>

purchase and (y) is in form and substance satisfactory to Lessor and Indenture
Trustee) and provided that Lessee shall have duly given the notice required by
the next succeeding sentence, Lessee shall have the right and, upon the giving
of such notice, the obligation to purchase any or all of the Units in a Basic
Group then leased hereunder (as specified in such notice) on the Early Purchase
Date for such Units at a price equal to the Early Purchase Price of such Units,
provided that if Lessee elects to purchase some but less than all of the Units
in any Basic Group, Lessee shall exercise such purchase with respect to at least
25 Units, no fewer than 25 Units shall remain in such Basic Group as a result of
such purchase and the determination as to which Units are to be purchased shall
be made on a random or other basis (in each case reasonably acceptable to
Lessor) without discrimination based on maintenance status, operating condition
of the Units in question or otherwise and such notice shall describe such manner
in which Lessee proposes to determine the Units in such Basic Group which will
be purchased. Lessee shall give Lessor written notice not less than 90 days
prior to the Early Purchase Date for the related Units of its election to
exercise the purchase option provided for in this Section 22.1(b), which notice
shall be irrevocable. Payment of the Early Purchase Price, together with all
other amounts due and owing by Lessee under the Operative Agreements, with
respect to such Units, including, without limitation, all unpaid Basic Rent
therefor due and payable on or prior to the Early Purchase Date (exclusive of
any in Basic Rent first becoming due on such date), plus an amount equal to the
Prepaid Adjustment Amount, if any, minus an amount equal to the Deferred
Adjustment Amount, if any, and any Make-Whole Amount with respect to the
Equipment Notes then being prepaid, shall be made on the Early Purchase Date at
the place of payment specified in Section 3.6 hereof in immediately available
funds against delivery of a bill of sale transferring and assigning to Lessee
all right, title and interest of Lessor in and to such Units on an "as-is"
"where-is" basis and containing a warranty against Lessor's Liens. Lessor shall
not be required to make any other representation or warranty as to the condition
of such Units or any other matters, and may specifically disclaim any such
representations or warranties. In the event of any such purchase and receipt by
Lessor of all of the amounts provided in this Section 22.1(b), the obligation of
Lessee to pay Basic Rent hereunder for such Units shall cease and the Lease Term
for such Units shall end.

               (c) Payment; Assumption of Equipment Notes. If the Lessee elects
to exercise either purchase option provided for in this Section 22.1, the Lessee
shall, as the purchase price therefor, in the sole discretion of the Lessee,
either (i) pay the applicable purchase price with respect to such Units,
together with all other amounts due and owing by the Lessee under the Operative
Agreements, or (ii) pay the difference between the Early Purchase Price and the
portion of the outstanding principal amount of the Equipment Notes which relates
to such Units as of the Early Purchase Date and assume on a full recourse basis,
and indemnify the Lessor against, all of the Owner Trustee's obligations under
the Indenture in respect of such portion of the indebtedness evidenced by such
Equipment Notes; provided, that, following such assumption, the purchased Units
shall remain subject to the lien of a separate indenture similar to the
Indenture pursuant to Section 3.06 of the Indenture. The Lessee will make the
payments required by foregoing clause (i) or assume such portion of the
indebtedness evidenced by the Equipment Notes which relates to such Units as
provided in foregoing clause (ii) on the Special Purchase Date with respect to
the purchase option described in Section 22.1(a) and on the Early Purchase Date
with respect to the purchase option described in Section 22.1(b), in immediately
available funds against delivery of a bill of sale transferring and assigning to
the Lessee all right, title and interest of the Lessor in and to the Units on an
"as-is" "where-is" basis and containing a

                                       35
<PAGE>

warranty against Lessor's Liens. In such event, the costs of preparing the bill
of sale and all other documentation relating to such purchase and the costs of
any necessary filings related thereto will be borne by the Lessee. If the Lessee
shall fail to fulfill its obligations under this Section 22.1(c), all of the
Lessee's obligations under the Lease and the Operative Agreements, including,
without limitation, the Lessee's obligation to pay installments of Rent, with
respect to the Units in question shall continue.

          Section 22.2   Election to Retain or Return Equipment at End of Basic
or Renewal Term.  Not less than 180 days prior to the end of the Basic Term, the
end of any Fixed Rate Renewal Term or the end of any Fair Market Renewal Term,
Lessee shall give Lessor irrevocable written notice of its decision to return or
retain any or all of the Units at the end of the Basic Term or such Renewal
Term, provided that if Lessee elects to retain less than all of the Units in a
Basic Group, Lessee must return at least 25 Units from such Basic Group to
Lessor and the determination as to which Units are to be retained shall be made
on a random or other basis (in each case reasonably acceptable to Lessor)
without discrimination based on maintenance status, operating condition of the
Units in question or otherwise, and Lessee shall describe in such notice such
manner in which it proposes to determine the Units in such Basic Group which
will be retained.  If Lessee elects to retain some or all of the Units, Lessee
shall comply with Section 22.3 and/or 22.4 hereof, as it may elect in accordance
with the provisions thereof including the notice requirements stated therein.
If Lessee fails to give the 180 days' notice required by this Section 22.2,
Lessee shall be deemed to have irrevocably elected to return all of the Units at
the end of the Basic Term or the applicable Renewal Term, as the case may be, in
accordance with Section 6.

          Section 22.3   Purchase Options.  Provided that no Material Default or
Lease Event of Default shall have occurred and be continuing either at the time
of notice or the expiration of the Lease Term (unless (i) Lessor shall have
waived such Material Default or Lease Default solely for the purpose of this
Section 22.3, (ii) in the case of a Lease Event of Default under Section 14(c),
14(d), 14(e), 14(f) or 14(i), Lessee shall have properly made a Special Purchase
Defeasance and after giving effect to the purchase described below, no such
Lease Event of Default shall be continuing or (iii) in the case of a Lease Event
of Default under Section 14(g) or 14(h), Lessee shall have obtained a final,
nonappealable order of a United States court having appropriate bankruptcy
jurisdiction over Lessee which (x) authorizes such purchase and (y) is in form
and substance satisfactory to Lessor and Indenture Trustee) and provided that
Lessee shall have duly given the notice required by Section 22.2 and by the next
succeeding sentence of this Section 22.3, Lessee shall have the right and, upon
the giving of such notice under this Section 22.3, the obligation to purchase
any or all of the Units (as specified in such notice, and subject to the minimum
number of Units and the criteria for selection of such Units referred to in
Section 22.2) either (x) at the expiration of the Basic Term at a price equal to
the Basic Term Purchase Price of such Units or (y) at the expiration of the
Basic Term or any Renewal Term at a price equal to the Fair Market Sales Value
of such Units as determined in accordance with Section 22.5 hereof.  Lessee
shall give Lessor written notice not less than 90 days prior to the end of the
Basic Term, the Fixed Rate Renewal Term or the Fair Market Renewal Term, as the
case may be, of its election to exercise the purchase option provided for in
this Section 22.3 (but in any event subject to the minimum number of Units
referred to in Section 22.2), which notice shall be irrevocable.  Payment of the
purchase price, together with all other amounts due and owing by Lessee under
the Operative Agreements, shall be made at the

                                       36
<PAGE>

place of payment specified in Section 3.6 hereof in immediately available funds
against delivery of a Bill of Sale transferring and assigning to Lessee all
right, title and interest of Lessor in and to such Units on an "as-is" "where-
is" basis and containing a warranty against Lessor's Liens. Lessor shall not be
required to make any other representation or warranty as to the condition of
such Units or any other matters, and may specifically disclaim any such
representations or warranties.

          Section 22.4   Renewal Options.  Provided that no Material Default or
Lease Event of Default shall have occurred and be continuing either at the time
of notice or the expiration of the Basic Term or any applicable Renewal Term
(unless Lessor shall have waived such Material Default or Lease Event of Default
solely for the purpose of this Section 22.4) and Lessee shall have duly given
the notice required by Section 22.2, Lessee shall have the right and, upon the
giving of a notice under this Section 22.4 as below provided, the obligation to
lease pursuant to this Lease any or all of the Units (as specified in such
notice, and subject to the minimum number of Units and the criteria for
selection of such Units referred to in Section 22.2) at the expiration of the
Basic Term or any applicable Renewal Term which Lessee has not elected to
purchase pursuant to Section 22.3, which obligation may be fulfilled by Lessee
electing to renew this Lease under either of the following Section 22.4(a) or
(b):

               (a) Fixed Rate. Lessee may give Lessor written notice not less
than 90 days prior to the end of the Basic Term (or, in the circumstances
described in the fourth sentence of this Section 22.4(a), the then Fixed Rate
Renewal Term) that Lessee elects to renew this Lease under this Section 22.4(a)
with respect to any or all of the Units (as specified in such notice, and
subject to the minimum number of Units and the criteria for selection of such
Units referred to in Section 22.2) then leased hereunder, for a term of one or
more years as Lessee shall specify in such notice (the "Fixed Rate Renewal
Term"), but in no event longer than the Outside Fixed Renewal Date, which notice
shall be irrevocable. In such event, promptly following such notice, a
determination in accordance with Section 22.5 shall be made of the date such
that (1) the period from the Closing Date to such date would not exceed 80% of
the useful life of such Units from and after the Closing Date, and (2) the Fair
Market Sales Value (determined without regard to inflation or deflation) on such
date would not be less than 20% of the Equipment Cost of such Units. Such date
shall thereafter be the latest date to which this Lease may be renewed pursuant
to this Section 22.4(a) (the "Outside Fixed Renewal Date"). Lessee shall
promptly following the determination of the Outside Fixed Renewal Date give
Lessor written notice of the Fixed Rate Renewal Term which Lessee selects for
its initial renewal under this Section 22.4(a), which in no event shall be
longer than the Outside Fixed Renewal Date. If Lessee selects a Fixed Rate
Renewal Term such that the period following such term until the Outside Fixed
Renewal Date is longer than one year, then Lessee may elect one or more further
renewals of one or more years pursuant to this Section 22.4(a) so long as no
such term extends beyond the Outside Fixed Renewal Date. The Basic Rent for each
Unit during any Fixed Rate Renewal Term (the "Fixed Rent") shall be for the
first such renewal, an amount equal to 105% of the average of the semiannual
Basic Rent installments payable hereunder for such Unit during the Basic Term,
and for any subsequent renewal under this Section 22.4(a), an amount equal to
the average of the semiannual Basic Rent installments payable hereunder for such
Unit during the Basic Term, payable semiannually in arrears provided, however,
if prior to the commencement of the first Fixed Rate Renewal Term, Lessee and
Owner Participant shall have received an opinion of Watson, Farley & Williams,
or of other independent counsel of national recognition selected by

                                       37
<PAGE>

the Owner Participant and reasonably acceptable to the Lessee (which the Owner
Participant agrees to seek at the request and expense of the Lessee) to the
effect that the elimination of such premium will not result in such renewal term
being includable in the "lease term", as defined in Treasury Regulation
(S)1.467-1(h)(6), or any successor thereto, in a manner that adversely affects
the Net Economic Return, such 5% premium above the average of the semi-annual
Basic Rent installments shall not be included in the first Fixed Rate Renewal
Term hereunder. Each Fixed Rate Renewal Term shall commence immediately upon the
expiration of the Basic Term or the preceding Fixed Rate Renewal Term, as the
case may be.

               (b) Fair Market. Lessee may give Lessor written notice not less
than 90 days prior to the end of the Basic Term, a Fixed Rate Renewal Term or a
Fair Market Renewal Term (subject to the limitations otherwise provided in this
Section 22.4(b)) that Lessee elects to renew this Lease under this Section
22.4(b) with respect to any or all of the Units (as specified in such notice,
and subject to the minimum number of Units and the criteria for selection of
such Units referred to in Section 22.2) then leased hereunder for a term of one
or more years as Lessee shall specify in such notice (the "Fair Market Renewal
Term"), which notice shall be irrevocable. The Basic Rent for the Units leased
during the Fair Market Renewal Term shall be determined in accordance with
Section 22.5 and shall be for the first such renewal, an amount equal to 105% of
the Fair Market Rental Value of such Units, and for any subsequent renewal under
this Section 22.4(b), an amount equal to the Fair Market Rental Value of such
Units, payable semiannually in arrears provided, however, if prior to the
commencement of the first Fixed Rate Renewal Term, Lessee and Owner Participant
shall have received an opinion of Watson, Farley & Williams, or of other
independent counsel of national recognition selected by the Owner Participant
and reasonably acceptable to the Lessee (which the Owner Participant agrees to
seek at the request and expense of the Lessee) to the effect that the
elimination of such premium will not result in such renewal term being
includable in the "lease term", as defined in Treasury Regulation
(S)1.467-1(h)(6), or any successor thereto, in a manner that adversely affects
the Net Economic Return, such 5% premium above Fair Market Rental Value shall
not be included in the first Fair Market Renewal Term hereunder. The Fair Market
Renewal Term shall commence immediately upon the expiration of the Basic Term or
the preceding Fixed Rate Renewal Term or Fair Market Renewal Term, as the case
may be.

          Section 22.5   Appraisal.  Promptly following Lessee's written notice
pursuant to Section 22.2 of its election to retain any Units at the end of the
Basic Term or a Renewal Term, as the case may be, Lessor and Lessee shall
determine the remaining useful life (based on the actual condition of a
reasonable sampling of such Units and determined pursuant to the appraisal
procedure set forth in the definition of Fair Market Sales Value) and the Fair
Market Sales Value and Fair Market Rental Value of the Units to be retained, in
each case assuming the Units are in the condition required by this Lease.
Promptly following Lessee's written notice pursuant to Section 22.1(a) of its
election to purchase any Units on the Special Purchase Date, Lessor and Lessee
shall determine the Fair Market Sales Value of the Units to be purchased,
assuming the Units are in the condition required by this Lease, which Fair
Market Sales Value shall be used to determine the Special Purchase Price, as
provided in Section 22.1(a).

          Section 22.6   Stipulated Loss Value and Termination Value During
Renewal Term.  All of the provisions of this Lease, other than Section 10, shall
be applicable during any renewal term for such Units, except as specified in the
next sentence.  During any Renewal Term,

                                       38
<PAGE>

the Stipulated Loss Value and Termination Value of any Unit shall be determined
on the basis of the Fair Market Sales Value of such Unit as of the first day of
such Renewal Term, assuming such Unit is in the condition required by this
Lease, reduced in equal monthly increments to the Fair Market Sales Value of
such Unit as of the last day of such Renewal Term; provided that in no event
during any Fixed Rate Renewal Term shall the Stipulated Loss Value and
Termination Value of any Unit be less than 20% of the Equipment Cost of such
Unit.

     SECTION 23.  Limitation of Lessor's Liability.  It is expressly agreed and
understood that all representations, warranties and undertakings of Lessor
hereunder (except as expressly provided herein) shall be binding upon Lessor
only in its capacity as Owner Trustee under the Trust Agreement and in no case
shall the Trust Company be personally liable for or on account of any
statements, representations, warranties, covenants or obligations stated to be
those of Lessor hereunder, except that Lessor (or any successor Owner Trustee)
shall be personally liable for its gross negligence or wilful misconduct and for
its breach of its covenants, representations and warranties contained herein to
the extent covenanted or made in its individual capacity.

     SECTION 24.  Investment of Security Funds.  Any moneys received by Lessor
or the Indenture Trustee pursuant to Section 12.2 which are required to be paid
to Lessee after completion of repairs to be made pursuant to Section 12.2 or
pursuant to Section 11.4(a) or 11.5, as the case may be, until paid to Lessee as
provided in Section 11.4(a), 11.5 or 12.2 or the curing of a Lease Default or
Lease Event of Default or as otherwise applied as provided herein or in the
Trust Agreement and Indenture, shall be invested at the risk and expense of
Lessee in Specified Investments by Lessor (unless the Indenture shall not have
been discharged, in which case, by the Indenture Trustee as provided in Section
6.04(b) of the Indenture) from time to time as directed by telephone (and
confirmed promptly thereafter in writing) by Lessee if such investments are
reasonably available for purchase.  There shall be promptly remitted to Lessee,
so long as no Material Default or Lease Event of Default shall have occurred and
be continuing, any gain (including interest received) realized as the result of
any such investment (net of any fees, commissions and other expenses, if any,
incurred in connection with such  investment) and Lessee will promptly pay to
Lessor or the Indenture Trustee, as the case may be, on demand, the amount of
any loss realized as the result of any such investment (together with any fees,
commissions and other expenses, if any, incurred in connection with such
investment), such amount to be disposed of in accordance with the terms of the
Trust Agreement and the Indenture.

     SECTION 25.  Miscellaneous.

          Section 25.1   Governing Law; Severability.  This Lease, and any
extensions, amendments, modifications, renewals or supplements hereto shall be
governed by and construed in accordance with the internal laws and decisions of
the State of New York; provided, however, that the parties shall be entitled to
all rights conferred by any applicable Federal statute, rule or regulation.
Whenever possible, each provision of this Lease shall be interpreted in such
manner as to be effective and valid under applicable law, but if any provision
of this Lease shall be prohibited by or invalid under the laws of any
jurisdiction, such provision, as to such jurisdiction, shall be ineffective to
the extent of such prohibition or invalidity, without invalidating the remainder
of such provision or the remaining provisions of this Lease in any other
jurisdiction.

          Section 25.2   Execution in Counterparts.  This Lease may be executed
in any number of counterparts, each executed counterpart constituting an
original and in each case such counterparts shall constitute but one and the
same instrument; provided, however, that to the extent that this Lease
constitutes chattel paper (as such term is defined in the Uniform Commercial
Code) no security interest in this Lease may be created through the transfer or
possession of any counterpart hereof other than the counterpart bearing the
receipt therefor executed by the Indenture Trustee on the signature page hereof,
which counterpart shall constitute the only "original" hereof for purposes of
the Uniform Commercial Code.

          Section 25.3   Headings and Table of Contents; Section References.
The headings of the sections of this Lease and the Table of Contents are
inserted for purposes of convenience only and shall not be construed to affect

Lease.

hereto and their respective permitted successors and assigns.

          Section 25.5   True Lease.  It is the intent of the parties to this
Lease that it will be a true lease and not a "conditional sale," and that Lessor
shall at all times be considered to be the owner of each Unit which is the
subject of this Lease for the purposes of all Federal, state, city and local
income taxes or for franchise taxes measured by income, and that this Lease
conveys to Lessee no right, title or interest in any Unit except as lessee.
Nothing contained in this Section 25.5 shall be construed to limit Lessee's use
or operation of any Unit or constitute a representation, warranty or covenant by
Lessee as to tax consequences.

          Section 25.6   Amendments and Waivers.  No term, covenant, agreement
or condition of this Lease may be terminated, amended or compliance therewith
waived (either generally or in a particular instance, retroactively or
prospectively) except by an instrument or instruments in writing executed by
each party hereto and except as may be permitted by the terms of the Indenture.

          Section 25.7   Survival. All warranties, representations, indemnities
and covenants made by either party hereto, herein or in any certificate or other
instrument delivered by such party or on the behalf of any such party under this
Lease, shall be considered to have been relied upon by the other party hereto
and shall survive the consummation of the transactions contemplated hereby on
the Closing Date regardless of any investigation made by either such party or on
behalf of either such party, and to the extent having accrued and not been paid
or relating to or otherwise arising in connection with the transactions
contemplated by the Operative Agreements during the Lease Term, shall survive
the expiration or other termination of this Lease or any other Operative
Agreement.

          Section 25.8   Business Days.  If any payment is to be made hereunder
or any action is to be taken hereunder on any date that is not a Business Day,
such payment or action otherwise required to be made or taken on such date shall
be made or taken on the immediately succeeding Business Day with the same force
and effect as if made or taken on such scheduled

                                       40
<PAGE>

date and as to any payment (provided any such payment is made on such succeeding
Business Day) no interest shall accrue on the amount of such payment from and
after such scheduled date to the time of such payment on such next succeeding
Business Day.

          Section 25.9   Directly or Indirectly.  Where any provision in this
Lease refers to action to be taken by any Person, or which such Person is
prohibited from taking, such provision shall be applicable whether such action
is taken directly or indirectly by such Person.

          Section 25.10   Incorporation by Reference.  The payment obligations
set forth in Sections 7.1 and 7.2 of the Participation Agreement are hereby
incorporated by reference.

                         ------------------
retain full legal title to and beneficial ownership of the Equipment

Lessee hereunder or any sublessee under any sublease permitted hereby.

          Section 4.2    Duty to Number and Mark Equipment.  With respect to the
                         ---------------------------------
Units to be delivered on the Closing Date, Lessee has caused, and as soon as
practicable after the date on which a Lease Supplement is executed and delivered
in respect of a Replacement Unit pursuant to Section 11.4(b), Lessee will cause,
each Unit to be numbered with its reporting mark shown on the Lease Supplement
dated the date on which such Unit was delivered and covering such Unit, and will
from and after such date keep and maintain, plainly, distinctly, permanently and
conspicuously marked by a plate or stencil printed in contrasting colors upon
each side of each Unit, in letters not less than one inch in height, a legend
substantially as follows:

     "OWNERSHIP SUBJECT TO A SECURITY AGREEMENT FILED WITH THE SURFACE
     TRANSPORTATION BOARD"

with appropriate changes thereof and additions thereto as from time to time may
be required by law in order to protect Lessor's right, title and interest in and
to such Unit, its rights under this Lease and the rights of the Indenture
Trustee.  Except as provided hereinabove, Lessee will not place any such Units
in operation or exercise any control or dominion over the same until the
required legend shall have been so marked on both sides thereof, and will
replace promptly any such word or words in such legend which may be removed,
defaced, obliterated or destroyed. Lessee will not change the reporting mark of
any Unit except in accordance with a statement of new reporting marks to be
substituted therefor, which statement shall be delivered by Lessee to Lessor
and, so long as the Indenture shall not have been discharged pursuant to its
terms, to the Indenture Trustee prior to or contemporaneously with such change.
A supplement to this Lease and, if not so discharged, the Indenture, with
respect to such new reporting marks, shall, prior to or contemporaneously with
the substitution of such reporting marks, be filed or recorded in all public
offices where this Lease and the Indenture shall have been filed or recorded and
in such other places, if any, where Lessor and, so long as the Indenture shall
not have been discharged pursuant to its terms, the Indenture Trustee may
reasonably request in order to protect, preserve and maintain its right, title
and interest in the Units.  The costs and expenses of all such supplements,
filings and recordings shall be borne by Lessee.

          Section 4.3    Prohibition Against Certain Designations.  Except as
                         ----------------------------------------
above provided, Lessee will not allow the name of any Person to be placed on any
Unit as a designation that might reasonably be interpreted as a claim of
ownership; provided, however, that subject to the delivery of the statement of

new reporting marks specified in Section 4.2, Lessee may cause the Equipment to
be lettered with the names or initials or other insignia customarily used by
Lessee or any permitted sublessees or any of their respective Affiliates on

                                          -----------------
a Lease Event of

<PAGE>

Default shall have occurred and be continuing, at Lessor's option, such power of
attorney shall terminate, and Lessor may assert and enforce, at Lessee's sole
cost and expense, such claims and rights. Lessor shall have no responsibility or
liability to Lessee or any other Person with respect to any of the following:
(i) any liability, loss or damage caused or alleged to be caused directly or
indirectly by any Unit, or by any of the commodities, items or materials from
time to time contained therein, whether or not permitted by the terms hereof, or
by any inadequacy thereof or deficiency or defect therein or by any other
circumstances in connection therewith; (ii) the use, operation or performance of
any Unit or any risks relating thereto; (iii) any interruption of service, loss
of business or anticipated profits or consequential damages; or (iv) the
delivery, operation, servicing, maintenance, repair, improvement or replacement
of any Unit. Lessee's delivery of a Lease Supplement shall be conclusive
evidence as between Lessee and Lessor that all Units described therein are in
all the foregoing respects satisfactory to Lessee, and Lessee will not assert
any claim of any nature whatsoever against Lessor based on any of the foregoing
matters.

      SECTION 6.  Return of Equipment; Storage.
                  ----------------------------

          Section 6.1    Return; Holdover Rent.     (a) Not less than 120 days
                         ---------------------
prior to the end of the Basic Term, the end of any Fixed Rate Renewal Term, or
the end of any Fair Market Renewal Term, in each case with respect to any Units
which Lessee has elected to return under Section 22.2, Lessee will provide
Lessor with a list of alternative storage locations used for the storage of
rolling stock within the continental United States (excluding Alaska) sufficient
to store the returned Units and the available storage capacities of such
locations.  Not less than 90 days prior to the end of the Lease Term with
respect to any Unit which has not been purchased by Lessee, Lessor will give
Lessee irrevocable notice of its decision either to take possession of or store
such Unit.  If Lessor shall have decided to take possession of such Unit, the
terms of Section 6.1(b) will apply.  If Lessor shall have decided to store such
Unit, the terms of Section 6.1(c) hereof will apply.

          (b) If Lessor shall have decided to take possession of such Unit,
Lessee will, at its sole risk and expense, deliver possession of such Unit at
any track location, f.o.b. such location, (i) as may be agreed upon by Lessor
and Lessee in writing or (ii) in the absence of such agreement, as Lessor may
reasonably direct by written notice to Lessee on or before the 90th day before
the end of the Lease Term; provided, that (x) such Units shall be returned to no
                           --------
more than five (5) interchange locations (each of which shall be located within
the continental United States, exclusive of Alaska), (y) there shall be no less
than 100 Units (or, if less than 100 Units are then subject to the Lease, all
Units), returned to each location, and (z) Lessor's notice shall specify the
total number and type of Units to be delivered to each location.

          (c) (i)  If Lessor shall have elected to store any Unit upon the
expiration of the Lease Term with respect thereto, Lessee shall store such Unit,
free of charge for a period (the "Storage Period") beginning, for any particular
                                  --------------
storage location, on the later of the expiration of the Lease Term and the date
on which 50% of the total number of Units being returned and stored at such
location have arrived thereat (the "Storage Period Commencement Date") and
                                    --------------------------------
ending not more than 45 days after the later of (A) the Storage Period
Commencement Date and (B) the date on which such Unit is in compliance with the
conditions

                                       5
<PAGE>

set forth in Section 6.2, and for an additional 60 days thereafter at the sole
risk and expense of Lessor. On or before the 90th day before the end of the
Lease Term, Lessor shall provide Lessee with written notice designating no more
than five (5) choices from among the alternative storage locations provided by
Lessee pursuant to Section 6.1(a), with a minimum of 100 Units to be stored per
location. Any storage provided by Lessee during the Storage Period (except for
such additional 60-day period referred to above) shall be at the sole risk and
expense of Lessee, and Lessee shall maintain the insurance required by Section
12.1 with respect to all stored Units; provided, however, any movement of the
                                       --------  -------
Units being stored in connection with Section 6 shall be at the risk and expense
of Lessor. During the Storage Period, Lessee will permit Lessor or any Persons
designated by it, including the authorized representative or representatives of
any prospective purchaser or user of such Unit, to restencil the marks on such
Unit and to inspect the same during Lessee's normal business hours upon at least
three Business Days' prior written or telephonic notice; provided, however, that
                                                         -----------------
such inspection and restenciling shall not interfere with the normal conduct of
Lessee's business; and provided, further, that (x) such inspection and
                       -----------------
restenciling shall be at such Person's own risk, (y) Lessee shall be protected
against any loss or damage incurred by it in connection with any such inspection
or restenciling by such Person through indemnification, insurance or other means
reasonably satisfactory to Lessee and (z) Lessee (except in the case of Lessee's
gross negligence or wilful misconduct) shall not be liable for any injury to, or
the death of, any person exercising, either on behalf of Lessor or any
prospective purchaser or user, the rights of inspection and restenciling granted
pursuant hereto. Lessee shall not be required to store the Equipment after the
Storage Period. If Lessee does store any Unit after the expiration of the
Storage Period, such storage shall be at the sole risk and expense of Lessor.

          (ii)   Upon the request and direction of Lessor (and at Lessor's sole
risk and expense), on not more than one occasion with respect to each stored
Unit and upon not less than 30 days' prior written notice from Lessor to Lessee,
Lessee will, on or before the expiration of the Storage Period, transport such
Units to any railroad interchange point or points within the continental United
States (except Alaska) (with a minimum of 100 Units (or, if less than 100 Units
are then subject to the Lease, all Units) per interchange point and to a maximum
of five (5) interchange points) on any railroad lines or to any connecting
carrier for shipment, whereupon Lessee shall have no further liability or
obligation with respect to such Units.

          (iii)  Upon receipt of Lessor's written notice designating its choices
from among the alternative storage locations provided by Lessee under Section
6.1(a), Lessee shall have the option to store such Units at such storage track
locations anywhere within the continental United States as it shall choose
(provided that there shall be no less than 100 Units (or, if less than 100 Units
are then subject to the Lease, all Units) stored at each such location). Upon
receipt of such notice, Lessee will promptly give notice to Lessor of the
locations at which Lessee will store such Units. If Lessee shall exercise such
option, (x) the Storage Period shall be extended an additional 30 days and (y)
Lessee shall on or before the expiration of the Storage Period transport such
Units to any railroad interchange point within the continental United States
(except Alaska) (with a minimum of 100 Units (or, if less than 100 Units are
then subject to the Lease, all Units) per interchange point and to a maximum of
five (5) interchange points) designated by Lessor upon not less than 30 days'
prior written notice. The movement of any Unit from such Unit's location as
designated by Lessee pursuant to this Section 6.1(c)(iii) to a location
thereafter designated by Lessor in accordance with the foregoing sentence will
be at the

                                       6
<PAGE>

risk and expense of Lessor. During any Storage Period, Lessee shall store the
Equipment in such manner as Lessee normally stores similar units of railroad
equipment owned or leased by it.

          (d) Upon the later of (i) expiration of the Lease Term with respect to
such Unit, (ii) tender of such Unit at the location determined in accordance
with Section 6.1(b) or, as applicable, the tender of such Unit for storage in
accordance with Section 6.1(c), and (iii) compliance by such Unit with Section
6.2, this Lease and the obligation to pay Basic Rent for such Unit accruing
subsequent to the expiration of the Lease Term with respect to such Unit shall
terminate.

          (e) So long as no Lease Event of Default has occurred and is
continuing, all amounts earned in respect of a Unit after the date of expiration
of the Lease Term with respect to such Unit and prior to the return of such Unit
hereunder shall belong to Lessee, and if received by Lessor, shall be promptly
turned over to Lessee.  In the event any Unit is not returned to Lessor in
accordance with the provisions of Section 6.1(b) on the last day of the Lease
Term with respect thereto, or if requested by Lessor pursuant to Section 6.1(c),
delivered and stored on such last day of the Lease Term, and, in either case, in
the condition specified in Section 6.2, Lessee shall pay to Lessor for each such
day from the expiration of the Lease Term with respect to such Unit until the
date on which such Unit is returned to Lessor in accordance with the provisions
of Section 6.1(b) and in the condition specified in Section 6.2, an amount equal
to the daily equivalent of the average Basic Rent for the Basic Term or the
Renewal Term as applicable to such Unit.  In the event Lessee is required to pay
such Rent subsequent to the expiration of the Lease Term with respect to a Unit
or Units, any amounts earned with respect to such Units shall be for the account
of Lessee.  If such Unit is not returned to Lessor in accordance with the
provisions of Section 6.1(b) and in the condition specified in Section 6.2 on or
prior to the 180th day after the expiration of the Lease Term with respect to
such Unit, Lessor shall have the right to require Lessee to purchase such Unit
for a purchase price equal to the Stipulated Loss Value for such Unit as of the
181st day after the expiration of such Lease Term; provided that if more than 25
                                                   --------
Units have not been returned on or prior to the expiration of such Lease Term,
the purchase price for such Unit shall be the higher of (x) the Fair Market
Sales Value, assuming such Unit is in the condition required by this Lease, and
(y) the Stipulated Loss Value of such Unit as of the 181st day after the
expiration of such Lease Term; provided further that, during the holdover period
                               ----------------
described in this sentence and the immediately preceding sentence, Lessee shall
use its best efforts to secure the return of the Equipment as required under
this Section 6 in the condition specified in Section 6.2.  Nothing herein shall
be in abrogation of Lessor's right to have such Unit returned to it for
possession or storage.  Payment of the purchase price, together with all other
amounts due and owing by Lessee under the Operative Agreements, shall be made at
the place of payment specified in Section 3.6 hereof in immediately available
funds against delivery of a bill of sale transferring and assigning to Lessee
all right, title and interest of Lessor in and to such Units on an "as-is"
"where-is" basis and containing a warranty against Lessor's Liens.  Lessor shall
not be required to make any other representation or warranty as to the condition
of such Units or any other matters except as to the absence of any Lessor's
Liens, and may specifically disclaim any such representations or warranties.

          Section 6.2    Condition of Equipment.  Each Unit when returned to
                         ----------------------
Lessor pursuant to this Section 6 shall be (i) capable of performing the
functions for which it was designed, with all loading and unloading components
operating in good working order with

                                       7
<PAGE>

allowance for normal wear and tear, (ii) suitable for continued commercial use
in the commodity last carried immediately prior to such return, (iii) suitable
for use in interchange by a new owner in the operating lease business in
accordance with then applicable Federal regulations (including but not limited
to AAR and FRA), (iv) in all material respects in the condition required by
Section 8.1, (v) in conformance with any requirement pertaining to warranties of
the manufacturer of the Units during the warranty period, (vi) empty, (vii)
steam cleaned or otherwise cleaned in a comparable commercially acceptable
manner, and (viii) free and clear of all Liens except Lessor's Liens and
Permitted Liens of the type described in clause (iii) of the definition of
Permitted Liens to the extent arising as a result of a fleet wide action which
includes such Unit. All logs, records, books and other materials relating to the
maintenance of such Unit shall, upon request, be delivered to Lessor or its
designee upon the return of such Unit. Lessor shall have the right to inspect
any Unit that is returned pursuant to Section 6.1 to ensure that such Unit is in
compliance with the conditions set forth in this Section 6.2, at Lessor's sole
cost, expense and risk (including, without limitation, the risk of personal
injury or death), by its authorized representatives, during Lessee's normal
business hours and upon reasonable prior notice to Lessee; provided, however,
                                                           -----------------
that Lessee shall not be liable for any injury to, or the death of, any Person
exercising, on behalf of Lessor, the rights of inspection granted under this
Section 6.2 unless caused by Lessee's gross negligence or wilful misconduct; and
further provided, that if such Unit is not in compliance with the conditions
----------------
set forth in this Section 6.2 then Lessee will (i) promptly take such steps as
are necessary to bring such Unit in compliance with the conditions set forth in
this Section 6.2 and (ii) pay the reasonable cost and expense of any
reinspection of such Unit conducted by Lessor required because of such non-
compliance with Section 6.2. No inspection pursuant to this Section 6.2 shall
interfere with the normal conduct of Lessee's business or the normal conduct of
any sublessee's business, and Lessee shall not be required to undertake or incur
any additional liabilities in connection therewith. A Unit shall not be deemed
to have been returned to Lessor for purposes of this Lease unless and until it
is in compliance with the conditions set forth in this Section 6.2.

      SECTION 7.  Liens.
                  -----

          Lessee will not directly or indirectly create, incur, assume, permit
or suffer to exist any Lien on or with respect to any Unit or Lessee's leasehold
interest therein under this Lease, except Permitted Liens, Lessor's Liens and
Liens described in Section 6.4(a) and 6.4(b) of the Participation Agreement.
Lessee shall promptly, at its own expense, take such action or cause such action
to be taken as may be necessary to duly discharge (by bonding or otherwise) any
such Lien not excepted above if the same shall arise at any time.

      SECTION 8.  Maintenance; Possession; Compliance with Laws.
                  ---------------------------------------------

          Section 8.1    Maintenance and Operation.   (a)  Lessee, at its own
                         -------------------------
cost and expense, shall maintain, repair and keep each Unit, (i) according to
prudent industry practice, in good working order, and in good physical condition
for railcars of a similar age and usage, normal wear and tear excepted, (ii) in
a manner consistent with maintenance practices used by Lessee in respect of
equipment owned or leased by Lessee similar in type to such Unit, (iii) in
accordance in all material respects with all manufacturer's warranties in effect
and in accordance with all applicable provisions, if any, of insurance policies
required to be maintained pursuant to Section 12, (iv) in compliance in all
material respects with any applicable laws and regulations,

                                       8
<PAGE>

including, without limitation, the Field Manual of the AAR, FRA rules and
regulations and Interchange Rules as they apply to the maintenance and operation
of the Equipment in interchange regardless of upon whom such applicable laws and
regulations are nominally imposed and (v) in a condition mechanically suitable
for interchange by an operator in revenue service; provided, however, that
                                                   -----------------
Lessee may, in good faith and by appropriate proceedings diligently conducted,
contest the validity or application of any such standard, rule or regulation in
any reasonable manner which does not materially interfere with the use,
possession, operation or return of any of the Units or materially adversely
affect the rights or interests of Lessor and the Indenture Trustee in the
Equipment or hereunder or otherwise expose Lessor, the Indenture Trustee or any
Participant to criminal sanctions or release Lessee from the obligation to
return the Equipment in compliance with the provisions of Section 6.2.  Lessee
shall provide Lessor and the Indenture Trustee with notice of any contest of the
type described in the preceding sentence in detail sufficient to enable Lessor
and the Indenture Trustee to ascertain whether such contest may have an effect
of the type described in the preceding sentence.  In no event shall Lessee
discriminate as to the use or maintenance of any Unit (including the periodicity
of maintenance or recordkeeping in respect of such Unit) as compared to
equipment of a similar nature which Lessee owns or leases.  Lessee will maintain
all records, logs and other materials required by relevant industry standards or
any governmental authority having jurisdiction over the Units required to be
maintained in respect of any Unit, all as if Lessee were the owner of such
Units, regardless of whether any such requirements, by their terms, are
nominally imposed on Lessee, Lessor or Owner Participant.

          (b) Without the written waiver or consent of Lessor (which waiver or
consent will not be unreasonably withheld), Lessee shall not or expressly permit
any sublessee to change a DOT classification (as provided for in 49 C.F.R. Part
179 or any successor thereto), or expressly permit any sublessee to operate any
Unit under a different DOT classification, from that classification in effect
for such Unit on the Closing Date, except for any change in tank test pressure
rating provided such change does not increase the pressure rating of the Unit
above the tank test pressure to which the Unit was manufactured; provided
                                                                 --------
however, that in the event Lessor shall not have provided Lessee with a written
-------
waiver or consent to such a reclassification or operation of any Unit within 10
Business Days after receipt of Lessee's written request therefor (or Lessor
expressly rejects such a request by Lessee), Lessee may replace such Unit in
accordance with and subject to the provisions of Section 11.2(i), 11.3 and 11.4.

          Section 8.2    Possession.  Lessee shall be entitled to the possession
                         ----------
of the Equipment and to the use of the Equipment by it or any Affiliate, in the
United States and, subject to the remaining provisions of this Section 8.2 and
Section 8.3, Canada and Mexico, only in the manner for which it was designed and
intended and so as to subject it only to ordinary wear and tear.  In no event
shall Lessee make use of any Equipment in any jurisdiction not included in the
insurance coverage required by Section 12.  The Equipment shall be used
primarily on domestic routes in the United States, and in no event shall more
than thirty-five percent (35%) of the Units (as determined by mileage records)
be assigned outside the United States at the same time until after December 31,
2007.  Thereafter, no more than forty-nine percent (49%) of the Units (as
determined by mileage records) shall be used outside the continental United
States (exclusive of Alaska) at the same time.  Notwithstanding the foregoing,
no more than 15% of the Units shall be used in Mexico so long as Mexican law
does not afford protections to the Lessor comparable to U.S. law and unless
Lessee shall first have taken all

                                       9
<PAGE>

actions necessary so as to protect the right, title and interest of Lessor and
the Indenture Trustee in the Equipment in Mexico pursuant to Section 16.3 and
shall have furnished Lessor and the Indenture Trustee with an opinion of Mexican
counsel, reasonably satisfactory to such parties, to the effect that all such
filings and recordings of the related Operative Agreements have been taken and
effected under such Mexican law. Nothing in this Section 8.2 shall be deemed to
constitute permission by Lessor to any Person that acquires possession of any
Unit to take any action inconsistent with the terms and provisions of this Lease
and any of the other Operative Agreements. The rights of any Person that
acquires possession of any Unit pursuant to this Section 8.2 shall be subject
and subordinate to the rights of Lessor hereunder.

          Section 8.3    Sublease.  Provided Lessor shall not have declared the
                         --------
Lease to be in default (or the Lease shall be deemed to have been declared in
default) pursuant to Section 15.1 hereof, Lessee shall be entitled, without the
prior approval of Lessor, to enter into a sublease for any Unit or Units
(pursuant to a car service contract or otherwise) to, or to grant permission for
the use thereof under car contracts by, (i) a railroad company or companies
incorporated under the laws of the United States of America or any state thereof
or the District of Columbia, Canada or any province thereof, or Mexico or any
state thereof, upon lines of railroad owned or operated by such railroad company
or companies or over which such railroad company or companies have trackage
rights or rights for operation of their trains, and upon connecting and other
carriers in the usual interchange of traffic or (ii) responsible companies
(i.e., a company with which Lessee would do business in the ordinary course of
Lessee's business with respect to railcars which it owns, leases or manages)
other than railroad companies for use in their business (leases to such
sublessees being herein referred to as "Permitted Subleases") provided, however,
                                        -------------------   -----------------
that Lessee shall not sublease more than 15% of the Units to a sublessee formed
under the laws of Mexico or any state thereof.  All subleases shall include
appropriate provisions so that such subleases, (i) shall in all events be
subject and subordinate to this Lease and the rights and interests of Lessor and
its respective successors and assigns hereunder and shall confirm such
subordination by a provision substantially in the form currently contained in
Lessee's standard car service contract delivered to Lessor and the Indenture
Trustee prior to the Closing Date, or otherwise as satisfactory to Lessor and
the Indenture Trustee, (ii) shall not be for a term which extends beyond the
Basic Term and any agreed upon Renewal Term, and (iii) shall not include any
term or provision which could reasonably be expected to result in material
adverse consequences to Lessor, Owner Participant or the Indenture Trustee.  In
the event Lessee desires to sublease one or more Units for a term which extends
beyond the Basic Term or any agreed upon Renewal Term, Lessee will have the
option to replace such Unit on or prior to the expiration of the Basic Term or
any Renewal Term, with another Unit in accordance with and subject to the
provisions of Section 11.2(i), 11.3 and 11.4.  Except in connection with an
assignment pursuant to a transaction permitted by Section 6.8 of the
Participation Agreement, no sublease entered into by Lessee hereunder shall
relieve Lessee of any liability or obligation hereunder, which shall be and
remain those of a principal and not a surety.  Nothing in this Section 8.3 shall
be deemed to constitute permission to any Person in possession of any Unit
pursuant to any such sublease to take any action inconsistent with the terms and
provisions of this Lease or any of the other Operative Agreements.

      SECTION 9.  Modifications.
                  -------------

          Section 9.1    Required Modifications.  In the event the AAR, the
                         ----------------------
United States Department of Transportation, or any other United States or state
governmental agency or any other applicable law requires that any Unit be
altered, replaced or modified (a "Required Modification"), Lessee agrees to make
                                  ---------------------
such Required Modification at its own expense; provided, however, that Lessee
                                               -----------------
may, in good faith and by appropriate proceedings diligently conducted, contest
the validity or application of any such law, regulation, requirement or rule in
any reasonable manner which does not materially interfere with the use,
possession, operation or return of any Unit or materially adversely affect the
rights or interests of Lessor and the Indenture Trustee in the Equipment or
hereunder or otherwise expose Lessor, the Indenture Trustee or any Participant
to criminal sanctions or relieve Lessee of the obligation to return the
Equipment in compliance with the provisions of Section 6.2.  Title to any
Required Modification shall immediately vest in Lessor.  Notwithstanding
anything herein to the contrary, if Lessee determines in good faith that any
Required Modification to a Unit would be economically impractical, in lieu of
making the Required Modification as provided above, Lessee may provide written
notice of such determination to Lessor and treat such Unit as if an Event of
Loss had occurred as of the date of such written notice with respect to such
Unit and in such event the provisions of Sections 11.2, 11.3 and 11.4 shall
apply with respect to such Unit; provided that Lessee shall not discriminate
                                 --------
against such Unit in making such determination of economic impracticality as
compared with other equipment of the same type as such Unit which is owned or
leased by Lessee.

          Section 9.2    Optional Modifications.  Lessee at any time may in its
                         ----------------------
discretion and at its own cost and expense modify, alter or improve any Unit in
a manner which is not required by Section 9.1 (a "Modification"); provided that
                                                  ------------
no Modification shall diminish the fair market value, utility, capacity, or
remaining economic useful life of such Unit below the fair market value,
utility, capacity, or remaining economic useful life thereof immediately prior
to such Modification, in any non de minimus respect, assuming such Unit was then
in the condition required to be maintained by the terms of this Lease, provided
                                                                       --------
that Lessee shall not discriminate against such Unit in making such
modification, alteration or improvement as compared with other equipment of the
same type as the Unit and which are owned or leased by the Lessee.  Title to any
Non-Severable Modification shall be immediately vested in Lessor.  Title to any
Severable Modification (other than Required Modifications) shall remain with
Lessee.  If Lessee shall at its cost cause such Severable Modifications (other
than Required Modifications) to be made to any Unit, Lessor shall have the
right, upon 90 days prior written notice in the case of a return other than
pursuant to Section 15.6, prior to the return of such Unit to Lessor hereunder,
to purchase such Severable Modifications (other than Severable Modifications
consisting of proprietary or communications equipment) at their then Fair Market
Sales Value (taking into account their actual condition).  If Lessor does not so
elect to purchase such Severable Modifications, Lessee may remove such Severable
Modifications at Lessee's cost and expense, and if requested (which request
shall be made by not less than 90 days prior written notice in the case of a
return other than pursuant to Section 15.6) by Lessor will so remove such
Severable Modifications at Lessee's cost and expense, and Lessee shall, at its
expense, repair any damage resulting from the removal of any such Severable
Modifications in a manner consistent with Section 8.1.

          Section 9.3    Removal of Property; Replacements.  Lessee may, in the
                         ---------------------------------
ordinary course of maintenance or repair of any Unit, remove any item of
property constituting a part of such Unit, and unless the removal of such item
is required by Section 9.1 hereof, Lessee shall replace such item as promptly as
practicable by an item of property that is free and clear of all Liens (other
than Permitted Liens) and in as good operating condition as, and with a fair
market value, utility, capacity and remaining economic useful life at least
equal to, the item of property being replaced, assuming that such replaced item
was in the condition required to be maintained by the terms of this Lease.  Any
item of property removed from such Unit in the ordinary course of maintenance
and repair as provided in the preceding sentence shall remain the property of
Lessor free and clear of all rights of Lessee until replaced in accordance with
the terms of such sentence, but shall then, without further act, become the
property of Lessee.  Any such property replaced in the ordinary course of
maintenance and repair shall, without further act, become the property of Lessor
and be deemed part of such Unit for all purposes hereof.

      SECTION 10.  Voluntary Termination.
                   ---------------------

          Section 10.1   Right of Termination.  So long as no Material Default
                         --------------------
or Lease Event of Default shall have occurred and be continuing, Lessee shall
have the right, at its option at any time or from time to time during the Basic
Term on or after the seventh anniversary of the Basic Term Commencement Date to
terminate the Lease Term with respect to any or all of the Units (provided that,
                                                                  --------
if such termination is for less than all Units in a Basic Group, Lessee shall
exercise such termination with respect to at least 25 Units, no fewer than 25
Units shall remain in such Basic Group as a result of such termination and the
determination as to which Units are subject to termination shall be made by
Lessee on a random or other basis (in each case reasonably acceptable to Lessor)
without discrimination based on maintenance status, operating condition of the
Units in question or otherwise) (the "Terminated Units") if Lessee determines in
                                      ----------------
good faith (as evidenced by a certified copy of a resolution adopted by Lessee's
Board of Directors and a certificate executed by the Chief Financial Officer of
Lessee) that such Units have become obsolete or surplus to Lessee's requirements
by delivering at least 120 days' prior notice to Lessor and the Indenture
Trustee (i) specifying a proposed date of termination for such Units (the
"Termination Date"), which date shall, except as provided in the last sentence
 ----------------
of Section 10.3, be a Rent Payment Date, any such termination to be effective on
the Termination Date upon Lessee's compliance with this Section 10, and (ii) if
some but less than all of the Units in a Basic Group are designated as
Terminated Units, describing the nondiscriminatory manner in which Lessee
proposes to determine which Units in that Basic Group are to be Terminated
Units.  Except as expressly provided herein, there will be no conditions to
Lessee's right to terminate this Lease with respect to the Terminated Units
pursuant to this Section 10.1.  So long as (a) Lessor shall not have given
Lessee a notice of election to retain the Terminated Units in accordance with
Section 10.3, or (b) notice of prepayment of the Equipment Notes shall not have
been given pursuant to Section 2.10 of the Indenture, Lessee may withdraw the
termination notice referred to above at any time prior to the Termination Date,
whereupon this Lease shall continue in full force and effect; provided that
                                                              --------
Lessee (i) may not exercise its right to withdraw such a termination notice more
than once annually or more than four times during the Basic Term, and (ii) may
not withdraw any termination notice with respect to any Terminated Units after
receipt by Lessee of a bid equal to or greater than Termination Value with
respect to such Terminated Units or later than sixty (60) days prior to the
scheduled Termination Date.  Lessee agrees that if it withdraws a termination
notice it will reimburse Lessor, Owner Participant and

                                       12
<PAGE>

the Indenture Trustee for all reasonable out-of-pocket costs and expenses
(including reasonable legal fees and expenses) incurred by any thereof in
connection therewith.

          Section 10.2   Sale of Equipment.  During the period from the date of
                         -----------------
such notice given pursuant to Section 10.1 to the Termination Date, Lessee, as
agent for Lessor and, except as provided in Section 10.3, at Lessee's sole cost
and expense, shall use reasonable best efforts to obtain bids from Persons other
than Lessee or Affiliates thereof for the cash purchase of the Terminated Units,
and Lessee shall promptly, and in any event at least five Business Days prior to
the proposed date of sale, certify to Lessor in writing the amount and terms of
each such bid, the proposed date of such sale and the name and address of the
party submitting such bid.  Unless Lessor shall have elected to retain the
Terminated Units in accordance with Section 10.3, on the Termination Date:  (i)
Lessee shall, subject to the prior or concurrent receipt (x) by Lessor of all
amounts owing to Lessor pursuant to the next sentence, and (y) by the Persons
entitled thereto of all unpaid Supplemental Rent due on or before the
Termination Date, deliver the Terminated Units (excluding any optional Severable
Modifications removed by Lessee pursuant to Section 9.2) to the bidder (which
shall not be Lessee or any Affiliate thereof), if any, which shall have
submitted the highest cash bid prior to such date (or to such other bidder as
Lessee and Lessor shall agree) and (ii) Lessor shall, without recourse or
warranty (except as to the absence of any Lessor's Lien) simultaneously
therewith transfer all of its right, title and interest in and to the Terminated
Units to such bidder.  The net proceeds of sale realized at such sale shall be
paid to and retained by Lessor and, in addition, on the Termination Date, Lessee
shall pay to Lessor, (A) all unpaid Rent with respect to such Terminated Units
due and payable on or prior to the Termination Date (exclusive of any Basic Rent
first becoming due on such date), (B) the excess, if any, of (1) the Termination
Value for the Terminated Units computed as of the Termination Date, over (2) the
net cash sales proceeds (after the deduction of all reasonable costs and
expenses of Lessor and Owner Participant in connection with such sale) of the
Terminated Units, and (C) an amount equal to the Make-Whole Amount, if any, in
respect of the principal amount of the Equipment Notes to be prepaid in
accordance with Section 2.10(a) of the Indenture; provided however, in the event
                                                  -------- -------
that the net cash proceeds with respect to such Units referred to above exceed
the Termination Value for such Units, then, (x) Lessee shall receive a credit
against amounts payable to Lessor pursuant to this Section 10.2 in an amount
equal to the lesser of (I) the Prepaid Adjustment Amount, if any, and (II) the
amount by which such net cash proceeds exceed the Termination Value for such
Units any (y) Lessee shall pay to Lessor an amount equal to the Deferred
Adjustment Amount, if any. If no sale shall have occurred, whether as a result
of Lessee's failure to pay all of the amounts hereinabove required or otherwise,
this Lease shall continue in full force and effect with respect to such Units
and Lessee agrees to reimburse Lessor, Owner Participant and the Indenture
Trustee for all reasonable costs and expenses (including reasonable legal fees
and expenses) incurred by any thereof in connection therewith; provided that if
                                                               --------
such sale shall not have occurred solely because of Lessee's failure to pay the
amounts hereinabove required, Lessee shall have no further right to terminate
this Lease with respect to such Units. Lessee, in acting as agent for Lessor,
shall have no liability to Lessor for failure to obtain the best price, shall
act in its sole discretion and shall be under no duty to solicit bids publicly
or in any particular market. Lessee's sole interest in acting as agent shall be
to use its reasonable best efforts to sell the Units at the highest price then
obtainable consistent with the terms of this Lease.

          Section 10.3   Retention of Equipment by Lessor.  Notwithstanding the
                         --------------------------------
provisions of Sections 10.1 and 10.2, Lessor may irrevocably elect by written
notice to Lessee,

                                       13
<PAGE>

no later than 60 days after receipt of Lessee's notice of termination, not to
sell the Terminated Units on the Termination Date, whereupon Lessee shall (i)
deliver the Terminated Units to Lessor in the same manner and condition as if
delivery were made to Lessor pursuant to Section 6.1(b) and Section 6.2,
treating the Termination Date as the termination date of the Lease Term with
respect to the Terminated Units, and (ii) pay to Lessor, or to the Persons
entitled thereto, all Rent due and owing on the Termination Date and unpaid
(exclusive of any in advance Basic Rent due on such date but inclusive of any
Supplemental Rent measured by the Make-Whole Amount). If Lessor elects not to
sell the Terminated Units as provided in this Section 10.3, then Lessor shall
pay, or cause to be paid, to the Indenture Trustee in funds of the type and in
an amount equal to the outstanding principal amount of the Equipment Notes
issued in respect of such Terminated Units and all accrued and unpaid interest
to the date of prepayment of such Equipment Notes on such Termination Date and
an amount equal to the Make-Whole Amount, if any, in respect of the principal
amount of the Equipment Notes to be prepaid without in any manner relieving the
Lessee of its obligation to pay any such amount pursuant to the preceding
sentence; provided that unless Lessor shall have paid all such amounts to the
          --------
Indenture Trustee on the Termination Date, this Lease shall continue in full
force and effect.  If Lessor shall fail to pay the amounts required pursuant to
this Section 10.3 and as a result thereof this Lease shall not be terminated
with respect to the Terminated Units on a proposed Termination Date, Lessor
shall (x) thereafter no longer be entitled to exercise its election to retain
such Terminated Units, and (y) reimburse Lessee for any reasonable out-of-pocket
expenses (including reasonable legal fees and expenses) incurred by it in
attempting to sell the Terminated Units pursuant to Section 10.2 immediately
prior to Lessor's exercise of such preemptive election, and Lessee may at its
option at any time thereafter prior to the immediately following Rent Payment
Date submit a new termination notice pursuant to Section 10.1 with respect to
such Terminated Units specifying a proposed Termination Date occurring on a
Determination Date occurring not earlier than 25 days from the date of such
notice.

          Section 10.4   Termination of Lease.  In the event of either (x) any
                         --------------------
such sale and receipt by Lessor and the Indenture Trustee of all of the amounts
provided in Section 10.2 or (y) retention of the Equipment and full performance
by Lessor of its payment obligations in compliance with Section 10.3, and upon
compliance by Lessee with the other provisions of this Section 10, the
obligation of Lessee to pay Basic Rent hereunder for such Terminated Units shall
cease and the Lease Term for the Terminated Units shall end.

      SECTION 11.  Loss, Destruction, Requisition, Etc.
                   ------------------------------------

          Section 11.1   Event of Loss.  In the event that any Unit (i) shall
                         -------------
suffer damage or contamination which, in Lessee's reasonable judgment (as
evidenced by an Officers' Certificate to such effect), makes repair uneconomic
or renders such Unit unfit for commercial use, (ii) shall suffer destruction, or
shall suffer theft or disappearance (after reasonable efforts by Lessee to
locate the same) for a period exceeding 12 months (or, if earlier, the end of
the Basic Term or Renewal Term then in effect), (iii) shall be permanently
returned to the manufacturer pursuant to any patent indemnity provisions, (iv)
shall have title thereto taken or appropriated by any governmental authority,
agency or instrumentality under the power of eminent domain or otherwise, (v)
shall be taken or requisitioned for use by (x) any governmental authority of
Mexico or any agency or instrumentality thereof under the power of eminent
domain or otherwise for a period in excess of the lesser of (A) 365 days and (B)
the remaining Basic Term

                                       14
<PAGE>

or any Renewal Term then in effect or (y) any other governmental agency or
instrumentality thereof under the power of eminent domain or otherwise for a
period in excess of the remaining Basic Term or any Renewal Term then in effect
(unless such taking or requisition is by any governmental authority, agency or
instrumentality other than the United States or Canada in which case such period
shall be the lesser of the period as aforesaid or 365 days) (any such occurrence
being hereinafter called an "Event of Loss"), Lessee, in accordance with the
                             -------------
terms of Section 11.2, shall promptly and fully inform Lessor and the Indenture
Trustee of such Event of Loss.

          Section 11.2   Replacement or Payment upon Event of Loss.  Upon the
                         -----------------------------------------
occurrence of (a) an Event of Loss or the deemed occurrence of an Event of Loss
pursuant to Section 9.1 or (b) an election to replace pursuant to Section 8.1(b)
or 8.3, with respect to any Unit, Lessee shall as soon as reasonably practical
and in any event within 60 days after a Responsible Officer of Lessee shall have
actual knowledge of such occurrence or election give Lessor and the Indenture
Trustee notice of such occurrence of such Event of Loss or election to replace
(which notice shall identify the Unit involved) and then within the 60-day
period following such notice give Lessor and the Indenture Trustee notice as to
which of the following options Lessee shall elect to perform (it being agreed
that if Lessee shall fail to give notice of such election, Lessee shall be
deemed to have elected to perform the option set forth in Section 11.2(ii)):

               (i) Upon Lessee's election to perform under this clause (i), as
     promptly as practicable following such election, and in any event on or
     before the 60th day following the date of notice of such Event of Loss or
     deemed Event of Loss pursuant to Section 9.1, or the date Lessee exercises
     an option to replace pursuant to Section 8.1(b) or Section 8.3, as the case
     may be, Lessee shall comply with Section 11.4(b) and shall convey or cause
     to be conveyed to Lessor a Replacement Unit to be leased to Lessee
     hereunder, such Replacement Unit to be of the same car type of the same or
     newer model year (or otherwise approved by Lessor, which approval shall not
     be unreasonably withheld), and free and clear of all Liens (other than
     Permitted Liens of the type described in clause (ii) with respect to
     sublessees, and in clauses (iii), (iv), (vi) and (vii) of the definition
     thereof) and to have a fair market value, utility, capacity, remaining
     economic useful life and condition at least equal to the Unit so replaced
     (assuming such Unit was in the condition required to be maintained by the
     terms of this Lease); provided that, if, at the time of such replacement,
                           --------
     only railcars (x) of a newer model year or (y) with a greater fair market
     value (or a greater Fair Market Sales Value in the situation set forth in
     the next proviso) than the replaced Units are available as Replacement
     Units, Lessee shall convey such Replacement Unit to Lessor as set forth
     above but Lessee may, at a later date, replace such Replacement Units with
     other Units that are closer in fair market value (or Fair Market Sales
     Value in the situation set forth in the next proviso) to the original
     replaced Units so long as such replacement does not result in any
     additional unindemnified tax liability; provided further that, if such
                                             ----------------
     replacement is performed (a) pursuant to Section 8.3 after the 180th day
     prior to the end of the Lease Term of such Units or (b) with respect to 15
     or more Units, each of such Replacement Units must have, in addition to the
     requirements set forth above, a Fair Market Sales Value at least equal to
     the Unit so replaced (assuming such Unit was in the condition required to
     be maintained by the terms of this Lease); provided further that, if Lessee
                                                ----------------
     shall elect the option under

                                       15
<PAGE>

     this clause (i) within such period but shall fail to perform its obligation
     to effect such replacement under this paragraph (i) within the 60-day
     period hereinabove provided for, then (except in the case of a failure to
     perform an election to replace pursuant to Section 8.1(b) or Section 8.3)
     at the end of such 60-day period Lessee shall immediately give Lessor and
     the Indenture Trustee notice of such failure and specify that Lessee shall
     pay to Lessor on the next succeeding Rent Payment Date that is at least 25
     days after the end of such 60-day period, or in the case of Supplemental
     Rent, to the Person entitled thereto, the amounts specified in paragraph
     (ii) below as of such next succeeding Rent Payment Date, and Lessee shall
     pay such amounts on such Rent Payment Date; provided further that Lessee
                                                 ----------------
     shall have no right to elect replacement under this clause (i) if at the
     time of the notice of the Event of Loss under Section 11.2 above a Material
     Default or Lease Event of Default shall have occurred and be continuing; or

               (ii)  on the Rent Payment Date which is not less than 25 days
     following the date of notice of Lessee's election to perform under this
     clause (ii), Lessee shall pay or cause to be paid to Lessor (or in the case
     of Supplemental Rent, to the Persons entitled thereto) in funds of the type
     specified in Section 3.6, (a) an amount equal to the Stipulated Loss Value
     of each such Unit suffering an Event of Loss or deemed Event of Loss
     determined as of such Rent Payment Date, (b) all Basic Rent payable on such
     date in respect of such Unit (exclusive of any Basic Rent first becoming
     due on such date) [and an amount equal to the Adjustment Amount (which
     amount, if negative, shall be a credit against amounts payable by Lessee
     pursuant to this Section 11.2(ii))], and (c) all other Rent then due and
     payable hereunder, it being understood that until such Stipulated Loss
     Value and other sums are paid, there shall be no abatement or reduction of
     Basic Rent;

provided that in the event at any time a Responsible Officer of Lessee shall
--------
have actual knowledge of the occurrence or deemed occurrence of an Event of Loss
with respect to an aggregate of 15 or more Units as to which Lessee would
otherwise be obligated to make payment pursuant to the second proviso to
paragraph (i) above or pursuant to paragraph (ii) above on a Rent Payment Date,
then Lessee shall thereupon give Lessor and the Indenture Trustee notice that in
lieu of making payments with respect to such Units as otherwise above provided
on a Rent Payment Date, Lessee will make a payment with respect to such Units on
the next succeeding Determination Date which is at least 25 days after such
notice, and on such Determination Date Lessee shall pay, in lieu of the amounts
otherwise required to be paid in respect of such Units on a Rent Payment Date as
provided above, (a) an amount equal to the Stipulated Loss Value of such Units
determined as of such Determination Date, (b) if such Determination Date is also
a Rent Payment Date, all Basic Rent payable on such date in respect of such
Units (exclusive of any in advance Basic Rent due on such date) and (c) all
other Rent then due and payable hereunder, it being understood that until such
Stipulated Loss Value and other sums are paid, there shall be no abatement or
reduction of Basic Rent.

obligated to pay all Rent in respect of such Unit or Units which is payable
under Section 11.2 with respect to such payment of Stipulated Loss Value or such
replacement of such Unit or Units and in respect of all other Units then
continuing to remain subject to this Lease.

                         ---------------------------------------------
Upon the payment of all sums required to be paid pursuant to Section 11.2 in
respect of any Unit or Units, Lessor will convey to Lessee or its designee all
right, title and interest of Lessor in and to such Unit or Units, "as is",
"where is", without recourse or warranty, except for a warranty against Lessor's
Liens, and shall execute and deliver to Lessee or its designee such bills of
sale and other documents and instruments as Lessee or its designee may
reasonably request to evidence such conveyance.  As to each separate Unit so
disposed of, so long as no Lease Event of Default shall have occurred and be
continuing, Lessee or its designee shall be entitled to any amounts arising from
such disposition, plus any awards, insurance or other proceeds and damages
received by Lessee, Lessor or the Indenture Trustee by reason of such Event of
Loss after having paid the Stipulated Loss Value and any other Rent attributable
thereto.

          (b) At the time of or prior to any replacement of any Unit or
Replacement Unit, Lessee, at its own expense, will (A) furnish Lessor with a

Lessee's counsel (which may be Lessee's General Counsel or Assistant General
Counsel), (x) to the effect that the Bill of Sale referred to in clause (A)
above constitutes an effective instrument for the conveyance of title to the
Replacement Unit to Lessor, and that legal and beneficial title to the
Replacement Unit has been delivered to Lessor, free and clear of all Liens
(other than Permitted Liens of the type described in clause (ii) with respect to
sublessees, and in clauses (iii), (iv), (vi) and (vii) of the definition

of title, Lessor will transfer to Lessee, "as is" and "where is" and without
recourse or warranty (except as to Lessor's Liens), all Lessor's right, title
and interest in and to the replaced Unit, and upon such transfer, Lessor will
request in writing that the Indenture Trustee execute and deliver to Lessee an
appropriate instrument releasing such replaced Unit from the lien of the
Indenture. Lessee shall pay all reasonable out of pocket costs and expenses
(including reasonable legal fees and expenses) incurred by Lessor, Owner
Participant and the Indenture Trustee in connection with any replacement
pursuant to this Section 11.4.

          Section 11.5   Eminent Domain.  In the event that during the Lease
                         --------------
Term the use of any Unit is requisitioned or taken by any governmental authority
under the power of eminent domain or otherwise for a period which does not
constitute an Event of Loss, all of Lessee's obligations under the Operative
Agreements, including without limitation, Lessee's obligation to pay all
installments of Basic Rent, shall continue for the duration of such
requisitioning or taking.  Lessee shall be entitled to receive and retain for
its own account all sums payable for any such period by such governmental
authority as compensation for requisition or taking of possession.  Any amount
referred to in this Section 11.5, in Section 11.4(a) or in Section 12 which is
payable to Lessee shall not be paid to Lessee, or if it has been previously paid
directly to Lessee, shall not be retained by Lessee, if at the time of such
payment a Lease Default under Section 14(g) or Section 14(h) or a Lease Event of
Default shall have occurred and be continuing, but shall be paid to and held by
Lessor pursuant to Section 24, or if the Indenture shall not then have been
discharged pursuant to its terms, to the Indenture Trustee, as security for the
obligations of Lessee under this Lease, and at such time as there shall not be
continuing any such Lease Default or Lease Event of Default, such amount shall
be paid to Lessee.

      SECTION 12.  Insurance.
                   ---------

          Section 12.1   Insurance.  Lessee will at all times after delivery and
                         ---------
acceptance of each Unit, at its own expense, keep or cause to be kept such Unit
insured by a reputable insurance company or companies in amounts and against
risks and with deductibles and terms and conditions not less than the insurance,
if any, maintained by Lessee with respect to similar equipment which it owns or
leases, but in no event shall such coverage be for amounts or against risks less
than the prudent industry standard for companies engaged in full service leasing
of railcars.  Without limiting the foregoing, Lessee will in any event:

                                       18
<PAGE>

          (a) keep each Unit of the Equipment insured against physical damage in
an amount not less than the Stipulated Loss Value attributable thereto as shown
on Schedule 4 to the Participation Agreement, subject to a limit of not less
than $10 million per occurrence (except for a $10 million annual aggregate each
for flood and earth movement), provided that such coverage may provide for
                               --------
deductible amounts of not more than $1,000,000 per occurrence; and

          (b) maintain public liability insurance naming Owner Participant, the
Lessor, the Trust Company and the Indenture Trustee as additional insureds (but
only with respect to liability arising out of or related to the Operative
Agreements and the Equipment) against bodily injury, death or property damage
arising out of the use or operation of the Equipment with general and excess
liability limits of not less than $50,000,000 per occurrence or in the
aggregate, provided that such coverage may provide for deductible amounts not
           --------
exceeding the lesser of (x) $10,000,000 or (y) 5% of the book value of the
railcar fleet of Lessee.

          It is understood and agreed that the insurance required hereunder may
be part of a company-wide insurance program, including risk-retention and self-
insurance.  Any policy of insurance maintained in accordance with this Section
12.1 and any policy purchased in substitution or replacement for any of such
policies shall provide that if any such insurance is cancelled or terminated for
any reason whatever (other than upon normal policy expiration), Lessor,
Indenture Trustee and Owner Participant shall receive 30 days' prior written
notice of such cancellation or termination.

          Section 12.2   Physical Damage Insurance.   (a)  The insurance
                         -------------------------
maintained pursuant to Section 12.1(a) shall provide that (i) so long as the
Equipment Notes remain outstanding, the proceeds up to the Stipulated Loss
Value, for any loss or damage to any Unit shall be made to the Indenture Trustee
under a standard loss payable clause, and thereafter to Lessor and (ii) so long
as no Lease Event of Default shall have occurred and be continuing, Lessee will
be entitled, at its own expense, to make all proofs of loss and take all other
steps necessary to collect the proceeds of such insurance.

          (b) In lieu of maintaining the physical damage insurance required by
Section 12.1(a), Lessee may self-insure with respect to the Equipment for such
amounts and against such risks as shall be consented to by Lessor and the
Indenture Trustee, which consent shall be based upon reasonable practices then
in effect in the railcar leasing and insurance industries and upon the financial
condition of Lessee.

          (c) The entire proceeds of any property insurance or third party
payments for damages to any Unit received by Lessor or the Indenture Trustee
shall be held by such party until, with respect to such Unit, the repairs
referred to in clause (i) below are made as specified therein or payment of the
Stipulated Loss Value is made, and such entire proceeds will be paid, so long as
no Lease Event of Default shall have occurred and be continuing, either:

                                       19
<PAGE>

                    (i)  to Lessee promptly following receipt by the Indenture
     Trustee or Lessor, as the case may be, of a written application signed by
     Lessee for payment to Lessee for repairing or restoring the Units which
     have been damaged so long as (1) Lessee shall have complied with the
     applicable provisions of the Lease, and (2) Lessee shall have certified
     that any damage to such Units shall have been fully repaired or restored;
     or

                    (ii) if this Lease is terminated with respect to such Unit
     because of an Event of Loss and Lessee has paid the Stipulated Loss Value
     due as a result thereof, such proceeds shall be promptly paid over to, or
     retained by, Lessee.

          Section 12.3   Public Liability Insurance.   (a)  The public liability
                         --------------------------
insurance referred to in paragraph 12.1(b) shall (i) provide that in as much as
such policies cover more than one insured, all terms, conditions, insuring
agreements and endorsements, with the exception of limits of liability and
liability for premiums, commissions, assessments or calls (which shall be solely
a liability of Lessee), shall operate in the same manner as if there were a
separate policy or policies covering each insured, (ii) waive any rights of
subrogation of the insurers against Owner Participant, Lessor, the Trust Company
and the Indenture Trustee, (iii) provide that none of Owner Participant, Lessor,
the Trust Company, or Indenture Trustee shall have any responsibility for any
insurance premiums, whether for coverage before or after cancellation or
termination of any such policies as to Lessee and (iv) be primary without
contribution from any similar insurance maintained by Owner Participant, Lessor
or the Indenture Trustee.

               (b)  Lessee shall use its reasonable efforts to obtain public
liability insurance policies stipulating that coverage thereunder will not be
invalidated (as to Owner Participant, Lessor, the Trust Company and the
Indenture Trustee) due to any action or inaction of Lessee or any other Person
(other than Owner Participant, Lessor or the Indenture Trustee, but only in
respect of their respective coverages), but shall be under no obligation to
obtain such policies containing such stipulations if they are not available to
Lessee at commercially reasonable rates in the markets in which Lessee has then
placed its insurance program.

               (c)  In the event any public liability insurance policy or
coverage thereunder which is required to be maintained under Section 12.1(b)
shall not be available to Lessee in the commercial insurance market on
commercially reasonable terms, Lessor shall not unreasonably withhold its
agreement to waive such requirement. Lessee shall make written request for any
such waiver in writing, accompanied by written reports prepared, at Lessee's
option, either by (i) one independent insurance advisor chosen by Lessee and
Lessor or (ii) three independent insurance advisors, one chosen by Lessor, one
chosen by Lessee and one chosen by the other two advisors (one of which may be
the regular insurance broker of Lessee), in either case, such independent
insurance advisors being of recognized national standing. The fees and expenses
of all such advisors shall be paid by Lessee. The written reports required
hereunder shall (x) state that such insurance (or the required coverage
thereunder) is not reasonably available to Lessee at commercially reasonable
premiums in the commercial insurance markets within which Lessee normally
purchases its insurance from insurers, acceptable to Lessee, with a Best's
rating of A- or better for railcars of similar type and capacity and (y) explain
in detail the basis for such conclusions. Upon the granting of any such waiver,
Lessee shall within 15 days thereafter certify to Lessor in writing the cost (on
a fleet-wide basis) of liability insurance

                                      20
<PAGE>

premiums for the coverage required by Section 12.1(b) for the immediately
preceding fiscal year; and in the event that any such certificate is not
received by Lessor within such 15 day period, any such waiver shall be deemed
revoked. At any time after the granting of such waiver, but not more often than
once a year, Lessor may make a written request for a supplemental report (in
form reasonably acceptable to Lessor) from such insurance advisor(s) updating
the prior report and reaffirming the conclusions set forth therein. Lessee shall
provide any such required supplemental report within 60 days after receipt of
the written request therefor. Any such waiver shall be effective for only as
long as such insurance is not reasonably available to Lessee in the commercial
markets in which Lessee normally purchases its insurance at commercially
reasonable rates, it being understood that the failure of Lessee to furnish
timely any such supplemental report shall be conclusive evidence that such
condition no longer exists. If such supplemental report shows that such coverage
is available, Lessee shall within 90 days of such report obtain such insurance
coverage. During any period with respect to which such waiver has been granted
and remains in effect under this Section 12.3(c), Lessee shall obtain public
liability insurance as set forth in Section 12.1(b) from such carriers, in such
amounts and with coverage limits and deductibles as is prudent under the
circumstances, but in any event in an amount that may be purchased for a premium
equal to 110% of Lessee's cost (on a fleet-wide basis) of public liability
insurance premiums for the coverage required by Section 12.1(b) for the fiscal
year immediately preceding the fiscal year in which such waiver first was
granted.

          Section 12.4   Certificate of Insurance.  Lessee shall, prior to the
                         ------------------------
Closing Date and when the renewal certificate referred to below is sent (but in
any event not less than annually), furnish Lessor, the Indenture Trustee and the
Owner Participant with a certificate signed by the insurer or an independent
insurance broker showing the insurance then maintained by Lessee pursuant to
this Section.  With respect to any renewal policy or policies, certificates or
binders evidencing such renewal shall be furnished as soon as practicable, but
in no event later than 30 days after the earlier of the date such renewal is
effected or the expiration date of the original policy or policies.
Simultaneously, with the furnishing of such certificate, Lessee will provide
appropriate evidence, reasonably satisfactory to Lessor and the Indenture
Trustee, that all premiums due on such insurance have been paid.

          Section 12.5   Additional Insurance.  In the event that Lessee shall
                         --------------------
fail to maintain insurance as herein provided, in Section 12.1 or, if
applicable, Section 12.3, Lessor may at its option, upon prior written notice to
Lessee, provide such insurance and, in such event, Lessee shall, upon demand
from time to time, reimburse Lessor for the cost thereof together with interest
from the date of payment thereof at the Late Rate, on the amount of the cost to
Lessor of such insurance which Lessee shall have failed to maintain.  If after
Lessor has provided such insurance, Lessee then obtains the coverage provided
for in Section 12.1 which was replaced by the insurance provided by Lessor, and
Lessee provides Lessor with evidence of such coverage reasonably satisfactory to
Lessor, Lessor shall cancel the insurance it has provided pursuant to the first
sentence of this Section 12.5.  In such event, Lessee shall reimburse Lessor for
all costs to Lessor of cancellation, including without limitation any short rate
penalty, together with interest from the date of Lessor's payment thereof at the
Late Rate.  In addition, at any time Lessor (either directly or in the name of
Owner Participant) may at its own expense carry insurance with respect to its
interest in the Units, provided that such insurance does not interfere with
Lessee's ability to insure the Equipment as required by this Section 12 or
adversely affect Lessee's insurance or the cost thereof, it being understood
that all salvage rights to each Unit

                                       21
<PAGE>

shall remain with Lessee's insurers at all times. Any insurance payments
received from policies maintained by Lessor pursuant to the previous sentence
shall be retained by Lessor without reducing or otherwise affecting Lessee's
obligations hereunder, other than with respect to Unit(s) with respect to which
such payments have been made.

      SECTION 13.  Reports; Inspection.
                   -------------------

          Section 13.1   Duty of Lessee to Furnish.  On or before April 30,
                         -------------------------
2001, and on or before each April 30 thereafter, Lessee will furnish to Lessor,
Owner Participant and the Indenture Trustee an accurate statement, as of the
preceding December 31, (a) showing the amount, description and reporting marks
of the Units then leased hereunder, the amount, description and reporting marks
of all Units that may have suffered an Event of Loss during the 12 months ending
on such December 31 (or since the Closing Date, in the case of the first such
statement), and such other information regarding the condition or repair of the
Equipment as Lessor may reasonably request, (b) stating that, in the case of all
Equipment repainted during the period covered by such statement, the markings
required by Section 4.2 hereof shall have been preserved or replaced, (c)
showing the percentage of use in each state in the United States and in both
Canada and Mexico based on the total mileage traveled by all railcars in
Lessee's fleet (or by the Units, if and to the extent generally made available
to Lessee in the ordinary course with respect to railcars in general interchange
service similar to the Units) for the prior calendar year as reported to Lessee
by railroads (provided, that Lessee shall cooperate with Owner Participant and
Lessor and shall provide such additional information on such matters as Owner
Participant or Lessor may reasonably request to enable Owner Participant and
Lessor to pursue or fulfill their respective tax audit and tax litigation rights
and obligations), and (d) stating that Lessee is not aware of any condition of
any Unit which would cause such Unit not to comply in any material respect with
the rules and regulations of the FRA and the interchange rules of the Field
Manual of the AAR as they apply to the maintenance and operation of the
Equipment in interchange.

          Section 13.2   Lessor's Inspection Rights.  Lessor, Owner Participant
                         --------------------------
and the Indenture Trustee each shall have the right, but not the obligation, at
their respective sole cost, expense and risk (including, without limitation, the
risk of bodily injury or death), by their respective authorized representatives,
to inspect (a) the Equipment and Lessee's records with respect thereto, and (b)
following the occurrence of a Lease Default and during the continuance thereof,
or following notice by Lessee that it will be returning any Unit to Lessor
pursuant to Section 10 or Section 22, any sublease of the Equipment and Lessee's
records with respect thereto.  All inspections shall be conducted during
Lessee's normal business hours, on Lessee's premises or in areas that are not
the premises of a sublessee to which Lessee has reasonable access, and upon
reasonable prior notice to Lessee.  Lessee shall not be liable for any injury
to, or the death of, any Person exercising, either on behalf of Lessor, any
Owner Participant, the Indenture Trustee or any prospective user, the rights of
inspection granted under this Section 13.2 unless caused by Lessee's gross
negligence or wilful misconduct.  No inspection pursuant to this Section 13.2
shall interfere with the use, operation or maintenance of the Equipment or the
ordinary course of Lessee's or any sublessee's business, and Lessee shall not be
required to undertake or incur any additional liabilities in connection
therewith.

      SECTION 14.  Lease Events of Default.
                   -----------------------

          The following events shall constitute Lease Events of Default
hereunder (whether any such event shall be voluntary or involuntary or come
about or be effected by operation of law or pursuant to or in compliance with
any judgment, decree or order of any court or any order, rule or regulation of
any administrative or governmental body) and each such Lease Event of Default
shall be deemed to exist and continue so long as, but only as long as, it shall
not have been remedied:

               (a) Lessee shall fail to make any payment of Basic Rent, Special
Purchase Price, Early Purchase Price, Basic Term Purchase Price or any other
purchase price to be paid by Lessee for any Units pursuant to this Lease or the
Participation Agreement, Stipulated Loss Value or Termination Value within 10
Business Days after the same shall have become due; or

               (b) Lessee shall fail to make any payment of Supplemental Rent,
including indemnity or tax indemnity payments, but not including Stipulated Loss
Value, Special Purchase Price, Early Purchase Price, Basic Term Purchase Price
or any other purchase price to be paid by Lessee for any Units pursuant to this
Lease or the Participation Agreement after the same shall have become due and
such failure shall continue unremedied for 10 Business Days after receipt by
Lessee of written notice of such failure from Lessor, Owner Participant or the
Indenture Trustee; or

               (c) Lessee shall fail to maintain in effect the insurance
required by Section 12 and such failure shall not have been waived as provided
for therein; or

               (d) Lessee shall make or permit any possession of the Equipment
or any portion thereof not permitted by this Lease, provided that such
                                                    --------
unauthorized possession shall not constitute a Lease Event of Default for a
period of 45 days after the occurrence thereof so long as (i) such unauthorized
possession is not the result of any willful action of Lessee and (ii) such
unauthorized possession is capable of being cured and Lessee diligently pursues
such cure throughout such 45-day period; or Lessee shall make or permit any
unauthorized assignment or transfer of this Lease in violation of Section 18.2;
or

               (e) Lessee shall fail to observe or perform any of the covenants
or agreements to be observed or performed by Lessee in Section 6.8 of the
Participation Agreement, and such failure shall continue unremedied for 30 days
during which period Lessee diligently pursues the cure of such failure; or

               (f) any representation or warranty made by Lessee in any Lessee
Agreement (other than the Tax Indemnity Agreement) is untrue or incorrect in any
material respect as of the date of making thereof and such untruth or
incorrectness shall continue to be material and unremedied for a period of 30
days after receipt by Lessee of written notice thereof from Lessor, Owner
Participant or the Indenture Trustee; provided that, if such untruth or
                                      --------
incorrectness is capable of being remedied, no such untruth or incorrectness
shall constitute a Lease Event of Default hereunder for a period of 60 days
after receipt of such notice so long as Lessee is diligently proceeding to
remedy such untruth or incorrectness and shall in fact remedy

                                      23
<PAGE>

such untruth or incorrectness within such period; provided that such untrue or
                                                  --------
incorrect representation or warranty shall be deemed to be remedied only after
all adverse consequences thereof, if any, have been remedied; or

               (g) Lessee 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

               (h) an involuntary case or other proceeding shall be commenced
against Lessee seeking liquidation, reorganization or other relief with respect
to it 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, and such involuntary case or other proceeding shall remain
undismissed and unstayed for a period of 60 days; or

               (i) Lessee shall fail to observe or perform any other of the
covenants or agreements to be observed or performed by Lessee under any Lessee
Agreement (other than the Tax Indemnity Agreement) or any certificate and such
failure shall continue unremedied for 30 days after notice from Lessor, Owner
Participant or the Indenture Trustee to Lessee, specifying the failure and
demanding the same to be remedied; provided that, if such failure is capable of
                                   --------
being remedied, and the remedy requires an action other than, or in addition to,
the payment of money, no such failure (other than one relating to the payment of
such money) shall constitute a Lease Event of Default hereunder for a period of
90 days after receipt of such notice so long as Lessee is diligently proceeding
to remedy such failure and shall in fact remedy such failure within such period;

provided that, notwithstanding anything to the contrary contained in this Lease,
--------
any failure of Lessee to perform or observe any covenant or agreement herein
shall not constitute a Lease Event of Default if such failure is caused solely
by reason of an event referred to in the definition of "Event of Loss" so long
                                                        -------------
as Lessee is continuing to comply with the applicable terms of Section 11.

      SECTION 15.  Remedies.
                   --------

          Section 15.1   Remedies.  Upon the occurrence of any Lease Event of
                         --------
Default and at any time thereafter so long as the same shall be continuing,
Lessor may, at its option, declare this Lease to be in default by a written
notice to Lessee (except that this Lease shall, without any action on the part
of Lessor, be automatically deemed to have been declared in default upon the
occurrence of a Lease Event of Default described in Section 14(g) or (h)); and
at any time thereafter, unless Lessee shall have remedied all outstanding Lease
Events of Default prior to the commencement of the exercise by Lessor of any of
its remedies hereunder, Lessor may do one or

                                       24
<PAGE>

more of the following as Lessor in its sole discretion shall elect, to the
extent permitted by, and subject to compliance with any mandatory requirements
of, applicable law then in effect:

          (a) proceed by appropriate court action or actions, either at law or
in equity, to enforce performance by Lessee of the applicable covenants of this
Lease or to recover damages for the breach thereof;

          (b) by notice in writing to Lessee, Lessor may demand that Lessee, and
Lessee shall, upon written demand of Lessor and at Lessee's expense, forthwith
return all or any part of the Equipment to Lessor or its order in the manner and
condition required by, and otherwise in accordance with all of the provisions of
Section 15.6; or Lessor with or without notice or judicial process may by its
agents enter upon the premises of Lessee or other premises where any of the
Equipment may be located and take possession of and remove all or any of the
Units, and Lessor may use and employ in connection with such removal any
services, aids, equipment, trackage and other facilities of Lessee as is
reasonably required to remove such Units and thenceforth hold, possess and enjoy
the same free from any right of Lessee, or its successor or assigns, to use such
Units for any purpose whatever;

          (c) sell any Unit at public or private sale in such manner as Lessor
may determine, free and clear of any rights of Lessee and without any duty to
account to Lessee with respect to such sale or for the proceeds thereof (except
to the extent required by paragraph (f) below if Lessor elects to exercise its
rights under said paragraph), in which event Lessee's obligation to pay Basic
Rent with respect to such Unit hereunder due for any periods subsequent to the
date of such sale shall terminate (except to the extent that Basic Rent is to be
included in computations under paragraph (e) or (f) below if Lessor elects to
exercise its rights under either of said paragraphs);

          (d) hold, keep idle or lease to others any Unit as Lessor in its sole
discretion may determine, free and clear of any rights of Lessee and without any
duty to account to Lessee with respect to such action or inaction or for any
proceeds with respect thereto, except that Lessee's obligation to pay Basic Rent
with respect to such Unit due for any periods subsequent to the date upon which
Lessee shall have been deprived of possession and use of such Unit pursuant to
this Section 15 shall be reduced by the net proceeds, if any, received by Lessor
from leasing such Unit to any Person other than Lessee;

          (e) whether or not Lessor shall have exercised, or shall thereafter at
any time exercise, any of its rights under paragraph (a), (b), (c) or (d) above
with respect to any Unit, Lessor, by written notice to Lessee specifying a
payment date (which date shall be a Determination Date for the purposes of
computing Stipulated Loss Value) which shall be not less than 30 days after the
date of such notice, may demand that Lessee pay to Lessor, and Lessee shall pay
to Lessor, on the payment date specified in such notice, as liquidated damages
for loss of a bargain and not as a penalty (in lieu of the Basic Rent for such
Unit due after the payment date specified in such notice), all Rent due and
payable, or accrued, for such Unit as of the payment date specified in such
notice (exclusive of any Basic Rent first becoming due on such date) plus
whichever of the following amounts Lessor, in its sole discretion, shall specify
in such notice: (i) an amount with respect to each such Unit which represents
the excess of the present value, at the time of such payment date, of all
rentals for such Unit which would otherwise have

                                       25
<PAGE>

accrued hereunder from such payment date for the remainder of the Basic Term or
any Renewal Term then in effect over the then present value of the then Fair
Market Rental Value of such Unit (taking into account its actual condition) for
such period computed by discounting from the end of such Term to such payment
date rentals which Lessor reasonably estimates to be obtainable for the use of
such Unit during such period, such present value to be computed in each case on
a basis of a per annum discount at the Debt Rate, compounded semiannually from
the respective dates upon which rentals would have been payable hereunder had
this Lease not been terminated plus an amount equal to the Deferred Adjustment
Amount, if any, provided, however, the Prepaid Adjustment Amount, if any, shall
be a credit against amounts payable by Lessee pursuant to this Section
15.1(e)(i); or (ii) an amount equal to the excess, if any, of the Stipulated
Loss Value for such Unit computed as of the payment date specified in such
notice over the Fair Market Sales Value of such Unit (taking into account its
actual condition) as of the payment date specified in such notice; or (iii) if
Lessor shall not have sold such Unit pursuant to the exercise of its rights
under paragraph (c) above with respect to such Unit, an amount equal to the
higher of Stipulated Loss Value for such Unit computed as of the payment date
specified in such notice or the Fair Market Sales Value of such Unit (assuming
it is in the condition required by this Lease) as of the payment date specified
in such notice, provided, however, in the event that the Fair Market Sales Value
with respect to such Unit referred to above exceeds Termination Value for such
Unit, then (a) Lessee shall receive a credit against amounts payable to Lessor
pursuant to this Section 15.1(e) (iii) in an amount equal to the lesser of (I)
the Prepaid Adjustment Amount, if any, and (II) the amount that such Fair Market
Sales Value exceeds the Termination Value for such Unit and (b) Lessee shall pay
to Lessor an amount equal to the Deferred Adjustment Amount, if any; and upon
payment by Lessee pursuant to said clause (iii) of such Stipulated Loss Value or
Fair Market Sales Value, as the case may be, and of all other amounts payable by
Lessee under this Lease and under the other Operative Agreements in respect of
such Unit, Lessor shall transfer "as is" and "where is" and without recourse or
warranty all right, title and interest of Lessor in and to such Unit to Lessee
or as it may direct, and Lessor shall execute and deliver such documents
evidencing such transfer as Lessee shall reasonably request;

          (f) if Lessor shall have sold any Unit pursuant to paragraph (c)
above, Lessor, in lieu of exercising its rights under paragraph (e) above with
respect to such Unit may, if it shall so elect, demand that Lessee pay to
Lessor, and Lessee shall pay to Lessor, as liquidated damages for loss of a
bargain and not as a penalty (in lieu of the Basic Rent for such Unit due
subsequent to the Rent Payment Date next preceding such sale), any accrued and
unpaid Rent for such Unit as of the date of such sale (Basic Rent for this
purpose accruing at a per diem rate equal to the semiannual amount due on the
next following Rent Payment Date divided by 180), plus the amount, if any, by
which the Stipulated Loss Value of such Unit computed as of the Rent Payment
Date next preceding the date of such sale or, if such sale occurs on a Rent
Payment Date, then computed as of such Rent Payment Date, exceeds the net
proceeds of such sale, plus interest on such amounts from the date of such sale
to the date of payment at the Late Rate; and

                                       26
<PAGE>

               (g) Lessor may terminate the leasing of any or all Units under
this Lease or may exercise any other right or remedy that may be available to it
under applicable law.

          In addition, Lessee shall be liable, except as otherwise provided
above, for any and all unpaid Rent due hereunder before or during the exercise
of any of the foregoing remedies (exclusive of any in advance Basic Rent due on
such date), and for legal fees and other costs and expenses incurred by reason
of the occurrence of any Lease Event of Default or the exercise of Lessor's
remedies with respect thereto, including without limitation the repayment in
full of any costs and expenses necessary to be expended in repairing any Unit in
order to cause it to be in compliance with all maintenance and regulatory
standards imposed by this Lease.

          Section 15.2   Cumulative Remedies.  The remedies in this Lease
                         -------------------
provided in favor of Lessor shall not be deemed exclusive, but shall be
cumulative and shall be in addition to all other remedies in its favor existing
at law or in equity.  Lessee hereby waives any mandatory requirements of law,
now or hereafter in effect, which might limit or modify any of the remedies
herein provided, to the extent that such waiver is permitted by law.  Lessee
hereby waives any and all existing or future claims of any right to assert any
offset or counterclaim against the Rent payments due hereunder, and agrees to
make the rent payments regardless of any offset or counterclaim or claim which
may be asserted by Lessee on its behalf in connection with the lease of the
Equipment.  Lessee further agrees that Lessee's obligations to pay all Rent
(including, without limitation, all Basic Rent and Supplemental Rent) and its
obligations to maintain the Equipment pursuant to Section 8 hereof and to
maintain the insurance pursuant to Section 12 hereof shall constitute monetary
obligations of the Lessee for all purposes of Section 365 of the Bankruptcy
Code.  To the extent permitted by applicable law, Lessee hereby waives any
rights now or hereafter conferred by statute or otherwise that may require
Lessor to sell, lease or otherwise use the Equipment in mitigation of Lessor's
damages as set forth in Section 15.1 or that may otherwise limit or modify any
of Lessor's rights and remedies provided in this Section 15.

          Section 15.3   No Waiver.  No delay or omission to exercise any right,
                         ---------
power or remedy accruing to Lessor upon any breach or default by Lessee under
this Lease shall impair any such right, power or remedy of Lessor, nor shall any
such delay or omission be construed as a waiver of any breach or default, or of
any similar breach or default hereafter occurring; nor shall any waiver of a
single breach or default be deemed a waiver of any subsequent breach or default.

          Section 15.4   Notice of Lease Default.  Lessee agrees to furnish to
                         -----------------------
Lessor, Owner Participant and the Indenture Trustee, promptly upon any officer
acquiring actual knowledge of any condition which constituted or constitutes a
Lease Default under this Lease, written notice specifying such condition and the
nature and status thereof.

          Section 15.5   Lessee's Duty to Furnish Information with Respect to
                         ----------------------------------------------------
Subleases. Upon the declaration of a Lease Event of Default pursuant to Section
---------
14(a), (b), (d) (with respect to the Units affected thereby), (g) or (h), Lessor
may request that Lessee deliver to Lessor, and

                                       27
<PAGE>

upon such request Lessee agrees that it will promptly provide to Lessor, a
detailed list of all Units that are then being subleased by Lessee, the identity
of the sublessees with respect to such Units, the identity of an employee or
other agent of each such sublessee with whom Lessee regularly communicates with
in respect of such Units and the most recent known location of such Units.

          Section 15.6   Lessee's Duty to Return Equipment Upon Default.  If
                         ----------------------------------------------
Lessor or any assignee of Lessor shall terminate this Lease pursuant to this
Section 15 and shall have provided to Lessee the written demand specified in
Section 15.1(b), Lessee shall forthwith deliver possession of the Equipment to
Lessor (except where Lessor has received all amounts payable by Lessee pursuant
to any notice provided by Lessor under Section 15.1(e)(iii)).  For the purpose
of delivering possession of any Unit to Lessor as above required, Lessee shall
at its own cost, expense and risk (except as hereinafter stated):

               (a) Forthwith place such Equipment upon such storage tracks of
Lessee or any of its affiliates or, at the expense of Lessee, on any other
storage tracks, as Lessor may designate or, in the absence of such designation,
as Lessee may select;

               (b) Permit Lessor to store such Equipment on such tracks without
charge for insurance, rent or storage until such Equipment has been sold, leased
or otherwise disposed of by Lessor and during such period of storage Lessee
shall continue to maintain all insurance required by Section 12.1 hereof; and

               (c) Transport the Equipment to any place on any lines of railroad
or to any connection carrier for shipment, all as Lessor may direct in writing.

All Equipment returned shall be in the condition required by Section 6.2 hereof.

          All amounts earned in respect of the Equipment after the date of
termination of this Lease pursuant to this Section 15, but not exceeding amounts
actually received therefor, shall be paid to Lessor or, so long as the Indenture
shall not have been discharged pursuant to its terms, the Indenture Trustee,
and, if received by Lessee, shall be promptly turned over to Lessor or the
Indenture Trustee as aforesaid.  In the event any Unit is not assembled,
delivered and stored as hereinabove provided within 15 days after the
termination of the leasing of such Unit pursuant to Section 15, Lessee shall, in
addition, pay to Lessor or the Indenture Trustee as aforesaid as liquidated
damages and not as a penalty, for each day thereafter an amount equal to the
amount, if any, by which the higher of (i) an amount equal to 110% of the daily
equivalent of the Basic Rent in effect immediately prior to the expiration of
the Lease for such Unit and (ii) 125% of the Fair Market Rental Value for such
Unit (determined upon the assumption that such Unit is in the condition required
by the terms of this Lease) for each such day exceeds the amount, if any,
received by Lessor or the Indenture Trustee as aforesaid (either directly or
from Lessee) for such day for such Unit pursuant to the preceding sentence.

          Section 15.7   Specific Performance; Lessor Appointed Lessee's Agent.
                         -----------------------------------------------------
The assembling, delivery, storage and transporting of the Equipment as provided
in Section 15.6 are of the essence of this Lease, and upon application to any
court of equity having jurisdiction in the premises, Lessor shall be entitled to
a decree against Lessee requiring specific performance of the

                                       28
<PAGE>

covenants of Lessee so to assemble, deliver, store and transport the Equipment.
Without in any way limiting the obligation of Lessee under the provisions of
Section 15.6, Lessee hereby irrevocably appoints Lessor as the agent and
attorney of Lessee, with full power and authority, at any time while Lessee is
obligated to deliver possession of any Units to Lessor pursuant to this Section
15, to demand and take possession of such Unit in the name and on behalf of
Lessee from whosoever shall be at the time in possession of such Unit.

      SECTION 16.  Filings; Further Assurances.
                   ---------------------------

          Section 16.1   Filings.   This Lease or a counterpart or copy hereof
                         -------
or evidence hereof may be filed or recorded in any public office as may be
necessary or appropriate to protect the interest of Lessor, Owner Participant or
the Indenture Trustee herein or in the Units.  On or prior to the Closing Date
Lessee will cause this Lease, the Lease Supplements dated the Closing Date, the
Indenture and the Indenture Supplements dated the Closing Date (i) to be duly
filed and recorded with the STB in accordance with 49 U.S.C. (S)11301, (ii) to
be deposited with the Registrar General of Canada pursuant to Section 105 of the
Canada Transportation Act (and all necessary actions shall have been taken for
publication of such deposit in The Canada Gazette in accordance with said
Section 105) and (iii) will furnish Lessor, the Indenture Trustee and Owner
Participant proof thereof.

          Section 16.2   Further Assurances.  Lessee will duly execute and
                         ------------------
deliver to Lessor such further documents and assurances and take such further
action as Lessor may from time to time reasonably request or as may be required
by applicable law or regulation in order to effectively carry out the intent and
purpose of this Lease and to establish and protect the rights and remedies
created or intended to be created in favor of Lessor, Owner Participant and the
Indenture Trustee hereunder, including, without limitation, the execution and
delivery of supplements or amendments hereto, in recordable form, subjecting to
this Lease any Replacement Unit and the recording or filing of counterparts
hereof or thereof in accordance with the laws of such jurisdiction as Lessor may
from time to time deem advisable.

          Section 16.3   Other Filings.  If, at any time during the Lease Term,
                         -------------
Mexico, or one or more states in Mexico, or any of the Canadian provinces
establishes a state or provincial or other system for filing and perfecting the
security and/or ownership interests of entities such as Lessor and/or the
Indenture Trustee, at the time that Lessee takes such action with respect to
other equipment similar to the Equipment (whether owned or leased by Lessee) and
also upon the request of Lessor, at the direction of the Owner Participant, or
the Indenture Trustee, Lessee 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 under such system to
be effected and taken, in order to perfect and protect the respective right,
title and interests of Lessor, Owner Participant and the Indenture Trustee.

          Section 16.4   Expenses.  Lessee will pay all costs, charges and
                         --------
expenses (including reasonable attorneys fees) incident to any such filing,
refiling, recording and rerecording or depositing and re-depositing of any such
instruments or incident to the taking of such action.

<PAGE>

      SECTION 17.  Lessor's Right to Perform.  If Lessee fails to make any
                   -------------------------
payment required to be made by it hereunder or fails to perform or comply with
any of its other agreements contained herein, Lessor may itself make such
payment or perform or comply with such agreement, after giving not less than
five Business Days' prior notice thereof to Lessee (except in the event that an
Indenture Default resulting from a Lease Default or a Lease Event of Default
shall have occurred and be continuing, in which event Lessor may effect such
payment, performance or compliance to the extent necessary to cure such
Indenture Default with notice given concurrently with such payment, performance
or compliance), but shall not be obligated hereunder to do so, and the amount of
such payment and of the reasonable expenses of Lessor incurred in connection
with such payment or the performance of or compliance with such agreement, as
the case may be, together with interest thereon at the Late Rate from such date
of payment, to the extent permitted by applicable law, shall be deemed to be
Supplemental Rent, payable by Lessee to Lessor on demand.

     SECTION 18.  Assignment.
                  ----------

          Section 18.1   Assignment by Lessor.  Lessee and Lessor hereby confirm
                         --------------------
that concurrently with the execution and delivery of this Lease, Lessor has
executed and delivered to the Indenture Trustee the Indenture, which assigns as
collateral security and grants a security interest in favor of the Indenture
Trustee in, to and under this Lease and certain of the Rent payable hereunder
(excluding Excepted Property), all as more explicitly set forth in the
Indenture.  Lessor agrees that it shall not otherwise assign or convey its
right, title and interest in and to this Lease, the Equipment or any Unit,
except as expressly permitted by and subject to the provisions of the
Participation Agreement, the Trust Agreement and the Indenture.

          Section 18.2   Assignment by Lessee.  Except as otherwise provided in
                         --------------------
Section 8.3 or in the case of any requisition for use by any governmental
authority or any agency or instrumentality thereof referred to in Section 11.1,
Lessee will not, without the prior written consent of Lessor and the Indenture
Trustee (which consent shall not be unreasonably withheld), assign any of its
rights hereunder, except as provided herein and in the Participation Agreement;
                            --------
provided that Lessee may assign its rights and/or obligations hereunder to any
--------
corporation in accordance with the provisions of Section 6.8 of the
Participation Agreement or to any corporation which is an Affiliate of Lessee,
provided that in the case of an assignment to an Affiliate, (a) Lessor shall
--------
have received an instrument or instruments reasonably satisfactory to it, Owner
Participant and the Indenture Trustee under which such Affiliate assumes the
obligations of Lessee hereunder, and (b) Lessee irrevocably and unconditionally
guarantees, pursuant to an agreement in form and substance reasonably
satisfactory to Lessor, Owner Participant and the Indenture Trustee, such
assignee's performance of all of such obligations as primary obligor and not as
a surety.

          Section 18.3   Sublessee's Performance and Rights.  Any obligation
                         ----------------------------------
imposed on Lessee in this Lease shall require only that Lessee perform or cause
to be performed such obligation, even if stated herein as a direct obligation,
and the performance of any such obligation by any permitted assignee, sublessee
or transferee under an assignment, sublease or transfer agreement then in effect
and permitted by the terms of this Lease shall constitute performance by Lessee
and discharge such obligation by Lessee.  Except as otherwise expressly

                                       30
<PAGE>

provided herein, any right granted to Lessee in this Lease shall grant Lessee
the right to (a) exercise such right or permit such right to be exercised by any
such assignee or transferee, or (b) in Lessee's capacity as sublessor pursuant
to any sublease permitted pursuant to Section 8.3 hereof, permit any sublessee
to exercise substantially equivalent rights under any such sublease as are
granted to Lessee under this Lease; provided, however, that Lessee's right to
                                    -----------------
terminate this Lease pursuant to Section 10 and Lessee's purchase and renewal
options set forth in Section 22 may be exercised only by Lessee itself or by any
assignee or transferee of, or successor to, Lessee in a transaction permitted by
Section 6.8 of the Participation Agreement; provided, further, that nothing in
                                            -----------------
this Section 18.3 shall or shall be deemed to (i) create any privity of contract
between any such sublessee, on the one hand, and any of Lessor, any Owner
Participant or any subsequent transferee or Affiliate of any such Person, on the
other hand, (ii) create any duty or other liability of any nature whatsoever on
the part of any of Lessor, any Owner Participant or any subsequent transferee or
Affiliate of any such Person, to any such sublessee or any Affiliate thereof, or
(iii) modify or waive any term or provision of Section 8.3 hereof, which Section
8.3 shall control if any conflict arises between any of the provisions thereof
and this Section 18.3. The inclusion of specific references to obligations or
rights of any such assignee, sublessee or transferee in certain provisions of
this Lease shall not in any way prevent or diminish the application of the
provisions of the two sentences immediately preceding with respect to
obligations or rights in respect of which specific reference to any such
assignee, sublessee or transferee has not been made in this Lease.

      SECTION 19.  Net Lease, etc.  This Lease is a net lease and Lessee's
                   ---------------
obligation to pay all Rent payable hereunder shall be absolute, unconditional
and irrevocable and shall not be affected by any circumstance of any character
including, without limitation, (i) any set-off, abatement, counterclaim,
suspension, recoupment, reduction, rescission, defense or other right that
Lessee may have against Lessor, Owner Participant, the Indenture Trustee or any
holder of an Equipment Note or Pass Through Certificate, any vendor or
manufacturer of any Unit, or any other Person for any reason whatsoever, (ii)
any defect in or failure of title, merchantability, condition, design,
compliance with specifications, operation or fitness for use of all or any part
of any Unit, (iii) any damage to, or removal, abandonment, requisition, taking,
condemnation, loss, theft or destruction of all or any part of any Unit or any
interference, interruption, restriction, curtailment or cessation in the use or
possession of any Unit by Lessee or any other Person for any reason whatsoever
or of whatever duration, (iv) any insolvency, bankruptcy, reorganization or
similar proceeding by or against Lessee, Lessor, Owner Participant, the
Indenture Trustee, any holder of an Equipment Note or Pass Through Certificate
or any other Person, (v) the invalidity, illegality or unenforceability of this
Lease, any other Operative Agreement, or any other instrument referred to herein
or therein or any other infirmity herein or therein or any lack of right, power
or authority of Lessee, Lessor, Owner Participant, the Indenture Trustee, any
holder of an Equipment Note or Pass Through Certificate or any other Person to
enter into this Lease or any other Operative Agreement or to perform the
obligations hereunder or thereunder or consummate the transactions contemplated
hereby or thereby or any doctrine of force majeure, impossibility, frustration
or failure of consideration, (vi) the breach or failure of any warranty or
representation made in this Lease or any other Operative Agreement by Lessee,
Lessor, Owner Participant, the Indenture Trustee, any holder of an Equipment
Note or Pass Through Certificate or any other Person, (vii) the requisitioning,
seizure or other taking of title to or use of such Unit by any government or
governmental authority or otherwise, whether or not by reason of any act or
omission of Lessor, Lessee or the Indenture Trustee, or any other deprivation or
limitation of

                                       31
<PAGE>

use of such Unit in any respect or for any length of time, whether or not
resulting from accident and whether or not without fault on the part of Lessee,
or (viii) any other circumstance or happening whatsoever, whether or not similar
to any of the foregoing. To the extent permitted by applicable law, Lessee
hereby waives any and all rights which it may now have or which at any time
hereafter may be conferred upon it, by statute or otherwise, to terminate,
cancel, quit or surrender this Lease with respect to any Unit, except in
accordance with the express terms hereof. If for any reason whatsoever this
Lease shall be terminated in whole or in part by operation of law or otherwise,
except as specifically provided herein, Lessee nonetheless agrees, to the
maximum extent permitted by law, to pay to Lessor or to the Indenture Trustee,
as the case may be, an amount equal to each installment of Basic Rent and all
Supplemental Rent due and owing, at the time such payment would have become due
and payable in accordance with the terms hereof had this Lease not been
terminated in whole or in part. Each payment of Rent made by Lessee hereunder
shall be final and Lessee shall not seek or have any right to recover all or any
part of such payment from Lessor or any Person for any reason whatsoever.
Nothing contained herein shall be construed to waive any claim which Lessee
might have under any of the Operative Agreements or otherwise or to limit the
right of Lessee to make any claim it might have against Lessor or any other
Person or to pursue such claim in such manner as Lessee shall deem appropriate.

     SECTION 20.  Notices.  Unless otherwise expressly specified or permitted by
                  -------

Trustee) and provided that Lessee shall have duly given the notice required by
the next succeeding sentence, Lessee shall have the right and, upon giving of
such notice, the obligation to purchase any or all of the Units then leased
hereunder (as specified in such notice) on the Special Purchase Date at a price
equal to the greater of the then applicable Termination Value for such Units and
the then current Fair Market Sales Value for such Units as determined in
accordance with Section 22.5 (the "Special Purchase Price"), provided that after
                                   ----------------------    --------

Group then leased hereunder (as specified in such notice) on the Early Purchase
Date for such Units at a price equal to the Early Purchase Price of such Units,

--------
in any Basic Group, Lessee shall exercise such purchase with respect to at least
25 Units, no fewer than 25 Units shall remain in such Basic Group as a result of
such purchase and the determination as to which Units are to be purchased shall
be made on a random or other basis (in each case reasonably acceptable to
Lessor) without discrimination based on maintenance status, operating condition

shall, as the purchase price therefor, in the sole discretion of the Lessee,
either (i) pay the applicable purchase price with respect to such Units,
together with all other amounts due and owing by the Lessee under the Operative
Agreements, or (ii) pay the difference between the Early Purchase Price and the

                                       35

portion of the outstanding principal amount of the Equipment Notes which relates
to such Units as of the Early Purchase Date and assume on a full recourse basis,
and indemnify the Lessor against, all of the Owner Trustee's obligations under
the Indenture in respect of such portion of the indebtedness evidenced by such
Equipment Notes; provided, that, following such assumption, the purchased Units
                 --------
shall remain subject to the lien of a separate indenture similar to the
Indenture pursuant to Section 3.06 of the Indenture.  The Lessee will make the
payments required by foregoing clause (i) or assume such portion of the
indebtedness evidenced by the Equipment Notes which relates to such Units as
provided in foregoing clause (ii) on the Special Purchase Date with respect to
the purchase option described in Section 22.1(a) and on the Early Purchase Date

obligations under this Section 22.1(c), all of the Lessee's obligations under
the Lease and the Operative Agreements, including, without limitation, the
Lessee's obligation to pay installments of Rent, with respect to the Units in
question shall continue.

without discrimination based on maintenance status, operating condition of the
Units in question or otherwise, and Lessee shall describe in such notice such
manner in which it proposes to determine the Units in such Basic Group which
will be retained.  If Lessee elects to retain some or all of the Units, Lessee
shall comply with Section 22.3 and/or 22.4 hereof, as it may elect in accordance
with the provisions thereof including the notice requirements stated therein.
If Lessee fails to give the 180 days' notice required by this Section 22.2,

either (x) at the expiration of the Basic Term at a price equal to the Basic
Term Purchase Price of such Units or (y) at the expiration of the Basic Term or

together with all other amounts due and owing by Lessee under the Operative
Agreements, shall be made at the place of payment specified in Section 3.6
hereof in immediately available funds against delivery of a Bill of Sale
transferring and assigning to Lessee all right, title and interest of Lessor in
and to such Units on an "as-is" "where-is" basis and containing a warranty
against Lessor's Liens. Lessor shall not be required to make any other
representation or warranty as to the condition of such Units or any other
matters, and may specifically disclaim any such representations or warranties.

          Section 22.4   Renewal Options.  Provided that no Material Default or
                         ---------------
Lease Event of Default shall have occurred and be continuing either at the time
of notice or the expiration of the Basic Term or any applicable Renewal Term
(unless Lessor shall have waived such Material Default or Lease Event of Default
solely for the purpose of this Section 22.4) and Lessee shall have duly given
the notice required by Section 22.2, Lessee shall have the right and, upon the
giving of a notice under this Section 22.4 as below provided, the obligation to
lease pursuant to this Lease any or all of the Units (as specified in such
notice, and subject to the minimum number of Units and the criteria for
selection of such Units referred to in Section 22.2) at the expiration of the
Basic Term or any applicable Renewal Term which Lessee has not elected to
purchase pursuant to Section 22.3, which obligation may be fulfilled by Lessee
electing to renew this Lease under either of the following Section 22.4(a) or
(b):

                    (a)  Fixed Rate.  Lessee may give Lessor written notice not
                         ----------
less than 90 days prior to the end of the Basic Term (or, in the circumstances
described in the fourth sentence of this Section 22.4(a), the then Fixed Rate
Renewal Term) that Lessee elects to renew this Lease under this Section 22.4(a)
with respect to any or all of the Units (as specified in such notice, and
subject to the minimum number of Units and the criteria for selection of such
Units referred to in Section 22.2) then leased hereunder, for a term of one or
more years as Lessee shall specify in such notice (the "Fixed Rate Renewal
                                                        ------------------
Term"), but in no event longer than the Outside Fixed Renewal Date, which notice
shall be irrevocable. In such event, promptly following such notice, a
determination in accordance with Section 22.5 shall be made of the date such
that (1) the period from the Closing Date to such date would not exceed 80% of
the useful life of such Units from and after the Closing Date, and (2) the Fair
Market Sales Value (determined without regard to inflation or deflation) on such
date would not be less than 20% of the Equipment Cost of such Units. Such date
shall thereafter be the latest date to which this Lease may be renewed pursuant
to this Section 22.4(a) (the "Outside Fixed Renewal Date"). Lessee shall
                              --------------------------
promptly following the determination of the Outside Fixed Renewal Date give
Lessor written notice of the Fixed Rate Renewal Term which Lessee selects for
its initial renewal under this Section 22.4(a), which in no

                                       37
<PAGE>

event shall be longer than the Outside Fixed Renewal Date. If Lessee selects a
Fixed Rate Renewal Term such that the period following such term until the
Outside Fixed Renewal Date is longer than one year, then Lessee may elect one or
more further renewals of one or more years pursuant to this Section 22.4(a) so
long as no such term extends beyond the Outside Fixed Renewal Date. The Basic
Rent for each Unit during any Fixed Rate Renewal Term (the "Fixed Rent") shall
                                                            ----------
be for the first such renewal, an amount equal to 105% of the average of the
semiannual Basic Rent installments payable hereunder for such Unit during the
Basic Term, and for any subsequent renewal under this Section 22.4(a), an amount
equal to the average of the semiannual Basic Rent installments payable hereunder
for such Unit during the Basic Term, payable semiannually in arrears provided,
                                                                     --------
however, if prior to the commencement of the first Fixed Rate Renewal Term,
-------
Lessee and Owner Participant shall have received an opinion of Watson, Farley &
Williams, or of other independent counsel of national recognition selected by
the Owner Participant and reasonably acceptable to the Lessee (which the Owner
Participant agrees to seek at the request and expense of the Lessee) to the
effect that the elimination of such premium will not result in such renewal term
being includable in the "lease term", as defined in Treasury Regulation
(S)1.467-1(h)(6), or any successor thereto, in a manner that adversely affects
the Net Economic Return, such 5% premium above the average of the semi-annual
Basic Rent installments shall not be included in the first Fixed Rate Renewal
Term hereunder. Each Fixed Rate Renewal Term shall commence immediately upon the
expiration of the Basic Term or the preceding Fixed Rate Renewal Term, as the
case may be.

               (b) Fair Market.  Lessee may give Lessor written notice not
                   -----------
less than 90 days prior to the end of the Basic Term, a Fixed Rate Renewal Term
or a Fair Market Renewal Term (subject to the limitations otherwise provided in
this Section 22.4(b)) that Lessee elects to renew this Lease under this Section
22.4(b) with respect to any or all of the Units (as specified in such notice,
and subject to the minimum number of Units and the criteria for selection of
such Units referred to in Section 22.2) then leased hereunder for a term of one
or more years as Lessee shall specify in such notice (the "Fair Market Renewal

Term"), which notice shall be irrevocable.  The Basic Rent for the Units leased
----
during the Fair Market Renewal Term shall be determined in accordance with
Section 22.5 and shall be for the first such renewal, an amount equal to 105% of
the Fair Market Rental Value of such Units, and for any subsequent renewal under
this Section 22.4(b), an amount equal to the Fair Market Rental Value of such
Units, payable semiannually in arrears provided, however, if prior to the
                                       --------  -------
commencement of the first Fixed Rate Renewal Term, Lessee and Owner Participant
shall have received an opinion of Watson, Farley & Williams, or of other
independent counsel of national recognition selected by the Owner Participant
and reasonably acceptable to the Lessee (which the Owner Participant agrees to
seek at the request and expense of the Lessee) to the effect that the
elimination of such premium will not result in such renewal term being
includable in the "lease term", as defined in Treasury Regulation (S)1.467-
1(h)(6), or any successor thereto, in a manner that adversely affects the Net
Economic Return, such 5% premium above Fair Market Rental Value shall not be
included in the first Fair Market Renewal Term hereunder.  The Fair Market
Renewal Term shall commence immediately upon the expiration of the Basic Term or
the preceding Fixed Rate Renewal Term or Fair Market Renewal Term, as the case
may be.

          Section 22.5   Appraisal.  Promptly following Lessee's written notice
                         ---------
pursuant to Section 22.2 of its election to retain any Units at the end of the
Basic Term or a Renewal Term, as the case may be, Lessor and Lessee shall
determine the remaining useful life (based on the

                                       38
<PAGE>

actual condition of a reasonable sampling of such Units and determined pursuant
to the appraisal procedure set forth in the definition of Fair Market Sales
Value) and the Fair Market Sales Value and Fair Market Rental Value of the Units
to be retained, in each case assuming the Units are in the condition required by
this Lease. Promptly following Lessee's written notice pursuant to Section
22.1(a) of its election to purchase any Units on the Special Purchase Date,
Lessor and Lessee shall determine the Fair Market Sales Value of the Units to be
purchased, assuming the Units are in the condition required by this Lease, which
Fair Market Sales Value shall be used to determine the Special Purchase Price,
as provided in Section 22.1(a).

          Section 22.6   Stipulated Loss Value and Termination Value During
                         --------------------------------------------------
Renewal Term.  All of the provisions of this Lease, other than Section 10, shall
------------
be applicable during any renewal term for such Units, except as specified in the
next sentence.  During any Renewal Term, the Stipulated Loss Value and
Termination Value of any Unit shall be determined on the basis of the Fair
Market Sales Value of such Unit as of the first day of such Renewal Term,
assuming such Unit is in the condition required by this Lease, reduced in equal
monthly increments to the Fair Market Sales Value of such Unit as of the last
day of such Renewal Term; provided that in no event during any Fixed Rate
                          --------
Renewal Term shall the Stipulated Loss Value and Termination Value of any Unit
be less than 20% of the Equipment Cost of such Unit.

      SECTION 23.  Limitation of Lessor's Liability.  It is expressly agreed and
                   --------------------------------
understood that all representations, warranties and undertakings of Lessor
hereunder (except as expressly provided herein) shall be binding upon Lessor
only in its capacity as Owner Trustee under the Trust Agreement and in no case
shall the Trust Company be personally liable for or on account of any
statements, representations, warranties, covenants or obligations stated to be
those of Lessor hereunder, except that Lessor (or any successor Owner Trustee)
shall be personally liable for its gross negligence or wilful misconduct and for
its breach of its covenants, representations and warranties contained herein to
the extent covenanted or made in its individual capacity.

     SECTION 24.  Investment of Security Funds.  Any moneys received by Lessor
                  ----------------------------
or the Indenture Trustee pursuant to Section 12.2 which are required to be paid
to Lessee after completion of repairs to be made pursuant to Section 12.2 or
pursuant to Section 11.4(a) or 11.5, as the case may be, until paid to Lessee as
provided in Section 11.4(a), 11.5 or 12.2 or the curing of a Lease Default or
Lease Event of Default or as otherwise applied as provided herein or in the
Trust Agreement and Indenture, shall be invested at the risk and expense of

been discharged, in which case, by the Indenture Trustee as provided in Section
6.04(b) of the Indenture) from time to time as directed by telephone (and
confirmed promptly thereafter in writing) by Lessee if such investments are
reasonably available for purchase.  There shall be promptly remitted to Lessee,
so long as no Material Default or Lease Event of Default shall have occurred and
be continuing, any gain (including interest received) realized as the result of
any such investment (net of any fees, commissions and other expenses, if any,
incurred in connection with such investment) and Lessee will promptly pay to
Lessor or the Indenture Trustee, as the case may be, on demand, the amount of
any loss realized as the result of any such investment (together with any fees,
commissions and other expenses, if any, incurred in connection with such
investment), such amount to be disposed of in accordance with the terms of the
Trust Agreement and the Indenture.
