Participant's name in Schedule 2 (the "Owner Participant's Commitment"). The
aggregate amount of the Owner Participant's Commitment plus the aggregate amount
of Transaction Costs payable by the Owner Participant shall not exceed the sum
of (x) the Owner Participant's Commitment and (y) 2.60% of the Total Equipment
Cost. The Owner Participant's Commitment shall be paid to the Indenture Trustee
to be held (but not as part of the Indenture Estate) and applied on behalf of
the Owner Trustee toward payment of the Total Equipment Cost as provided in
Section 2.3.

            (b) Debt Participation. On the Closing Date, subject to the terms
and conditions hereof and on the basis of the representations and warranties set
forth herein, the Loan Participant agrees to participate in the payment of the
Total Equipment Cost for the Units delivered on the Closing Date by making a
secured loan, not from its own funds but solely from the Consideration (as
defined in the Pass Through Trust Agreement) received by it from the sale of the
Pass Through Trust Certificates, to be evidenced by the Equipment Note, to the
Trust, in the amount equal to the product of the Total Equipment Cost for the
Units delivered on the Closing Date and the percentage (not in excess of 80%)
set forth opposite the Loan Participant's name in Schedule 2 (the "Loan
Participant's Commitment"). The Equipment Note shall bear interest at the Debt
Rate.

      Section 2.3 Closing Date; Procedure for Participation.

            (a) Notice of Closing Date. Not later than three Business Days prior
to the Closing Date (or such lesser notice as may be agreed upon by the Lessee,
the Owner Participant and the Loan Participant), the Lessee shall give the Owner
Participant, the Indenture Trustee, the Trust, the Owner Trustee, the Policy
Provider and the Loan Participant a notice (a "Notice of Delivery") by facsimile

reasonable detail the number and type of Units to be delivered on such date, the
Total Equipment Cost of such Units, and the respective amounts of the Owner
Participant's Commitment and the Loan Participant's Commitment required to be
paid with respect to the Units. Prior to 11:00 a.m., Chicago time, on the
Closing Date, subject to the satisfaction (or waiver) of the respective
conditions specified in Section 4, the Owner Participant shall make the amount
of the Owner Participant's Commitment required to be paid on the Closing Date
available to the Indenture Trustee, and immediately prior to the delivery and
acceptance of the Units as specified in Section 2.3(b), the Loan Participant
shall make the amount of the Loan Participant's Commitment for the Total
Equipment Cost required to be paid on the Closing Date available to the
Indenture Trustee, in either case, by transferring or delivering such amounts,

Owner Participant's Commitment for the Total Equipment Cost shall be deemed a
waiver of the Notice of Delivery by the Owner Participant and the Trust. The
making available by the Loan Participant of the amount of the Loan Participant's
Commitment for the Total Equipment Cost shall be deemed a waiver of the Notice
of Delivery by the Loan Participant and the Indenture Trustee.

            (b) Closing. The closing of the transactions contemplated hereby
(the "Closing") shall take place on or before 2:00 p.m., Chicago time, on the
Closing Date at the Chicago offices of Winston & Strawn LLP, or at such other

Participants or waived by the applicable Participants, pay to the Lessee from
the funds then held by it, in immediately available funds, an amount equal to
the Total Equipment Cost for the Units delivered on the Closing Date, (ii) the
Lessee shall pay to TRLTII pursuant to the Transfer and Assignment Agreement an
amount equal to the Total Equipment Cost for the Units delivered on the Closing
Date, (iii) the Lessee shall deliver the Units described on Schedule 1-A hereto
to the Trust by delivery of the Bill of Sale, (iv) the Trust shall, pursuant to
the Lease, lease and deliver the Units listed on Schedule 1-A hereto to the
Lessee, and the Lessee, pursuant to the Lease, shall accept delivery of the
Units described on Schedule 1-A hereto under the Lease, and such lease, delivery
and acceptance of such Units under the Lease shall be conclusively evidenced by
the execution and delivery by the Lessee and the Trust of the Lease Supplement
covering the Equipment so delivered as described in Schedule 1-A and (v) the
Trust shall execute (and the Indenture Trustee shall authenticate) and deliver
the Equipment Note relating to such Lease Supplement to the Loan Participant.
Concurrently with the transactions described immediately above, TRLTII shall
pursuant to the Pledged Equipment Transfer and Assignment Agreement sell the
Pledged Units described on Schedule 1-B hereto to the Lessee by delivery of the
Pledged Equipment Bill of Sale and shall make an assignment of the Existing
Pledged Equipment Leases to the Lessee by delivery of the TRLTII Pledged
Equipment Assignment. Each of the Lessee, the Owner Participant, the Trust, the
Owner Trustee, TILC, the Loan Participant and the Indenture Trustee hereby
agrees to take all actions required to be taken by it in connection with the
Closing as contemplated by this Section 2.3(b).

                                       8
<PAGE>

expenses relating to any voluntary transfer of any Certificateholder's interest

            (c) To the extent Transaction Costs exceed 2.6% of the Total
Equipment Cost, Lessee shall pay such excess Transaction Costs. For purposes of
Section 2.5, the Transaction Costs described in Sections 2.5(a)(ii), (a)(iv),

      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 August 19, 2004, (B) the actual interest rate on the
Equipment Note is different from the Debt Rate or the amortization of the
Equipment Note is different from that set forth on Schedule 5, (C) a refinancing
contemplated by Section 10.2 occurs, (D) the actual aggregate Equipment Cost or
composition of the Units is different from that set forth on Schedule 1-A, (E)
the actual aggregate amount of Transaction Costs paid pursuant to Section 2.5(a)
is other than an amount equal to 2.6% of the Total Equipment Cost, or (F) there
is any proposed or actual change in the Code or in the regulations promulgated
thereunder or other administrative pronouncement, which change is enacted or
effective after the execution of this Agreement and prior to the Closing Date
(provided that the Owner Participant or the Lessee, as the case may be, shall
have provided notice to the other prior to the Closing Date), and which change
alters or eliminates any tax assumption used in calculating Basic Rent,
Stipulated Loss Values, Stipulated Loss Amounts, Termination Values, Termination
Amounts or Early Purchase Price, 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, Stipulated Loss Amounts, Termination Values, Termination
Amounts and Early Purchase Price (i) first, to preserve the Net Economic Return
that the Owner Participant would have realized had such event not occurred, and
(ii) second, to minimize to the greatest extent possible, consistent with the
foregoing clause (i), the present value (discounted monthly at an interest rate
per annum equal to the Debt Rate) of the sum of the payments of Basic Rent to
the Early Purchase Date and the Early Purchase Price; provided, however, that in
no event shall the Early Purchase Price be less than the expected fair market
value of the Equipment on the Early Purchase Date and the Basic Term Expiration
Date, respectively, as determined by the Appraisal. Any such recalculation
performed due to the occurrence of any one or more of the events described in
clause (A), (B), (D), (E) or (F) above shall be made prior to the Closing 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,

                                       9
<PAGE>

Stipulated Loss Amounts, Termination Values, Termination Amounts and Early
Purchase Price initially set forth in Schedules 3-A, 3-B, 4-A, 4-B and 6 (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 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) with Section 467 of the Code and the
requirements of Revenue Procedure 2001-28, 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).

            (b) Confirmation and Verification. Upon completion of any
recalculation described in Section 2.6(a), a duly authorized officer of the
Owner Participant shall provide a certificate to the Lessee either (x) stating
that the amounts of Basic Rent, Stipulated Loss Values, Stipulated Loss Amounts,
Termination Values, Termination Amounts and Early Purchase Price as are then set
forth in Schedules 3-A, 3-B, 4-A, 4-B and 6 do not require change, or (y)
setting forth such adjustments to the amounts of Basic Rent, Stipulated Loss
Values, Stipulated Loss Amounts, Termination Values, Termination Amounts or
Early Purchase Price as have been calculated by the Owner Participant in
accordance with Section 2.6(a). 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 and
Early 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, in the case of adjustments made pursuant to clause (A), (B),
(D), (E) or (F) of the first sentence of Section 2.6(a), 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, and, in the case of an adjustment
made pursuant to clause (C) of the first sentence of Section 2.6(a), as of the
date of the refinancing. If the Lessee shall so request, the recalculation of
any such adjustments described in this Section 2.6 shall be verified 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, subject to a confidentiality agreement reasonably satisfactory
to the Owner Participant, such information as it may reasonably require, 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 or its affiliates have any obligation to provide the Lessee with any
such information; and provided, further, that the Owner Participant or its
affiliates 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 its affiliates, 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 in a decrease in the net present value
(expressed as a percentage of Total Equipment Cost, discounted monthly at a rate
per annum equal to the Debt Rate) of the sum of the Basic Rent to the Early
Purchase Date and

                                       10
<PAGE>

the Early Purchase Price, calculated as of the Closing Date, as compared to the
net present value of the sum of the Basic Rent to the Early Purchase Date and
the Early Purchase Price, proposed by the Owner Participant, by more than the
greater of (i) ten basis points and (ii) 5% 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, in the case of an adjustment pursuant to clause (C) of
the first sentence of Section 2.6(c), such adjustment shall be effective as of
the date of the refinancing).

            (c) Compliance. Notwithstanding the foregoing, any adjustment made
to the payments of Basic Rent, Stipulated Loss Amounts, Termination Amounts or
Early Purchase Price, 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
Trust to pay in full as of the due date of such installment an amount equal to
the sum of (x) any payment of principal of and interest on the Equipment Note
required to be paid on the due date of such installment of Basic Rent in
accordance with the Scheduled Amortization and (y) an amount equal to the Policy
Provider Base Premium Amount required to be paid on the due date of such
installment of Basic Rent, and (ii) Stipulated Loss Amount, Termination Amount
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
and all unpaid interest on the Equipment Note in accordance with the Scheduled
Amortization accrued to the date on which Stipulated Loss Amount, Termination
Amount 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) If for any reason whatsoever the Closing is not consummated on
the Closing Date provided for pursuant to Section 2.3 (the "Scheduled Closing
Date"), the Closing shall be deemed postponed to the next Business Day or to
such other Business Day on or prior to August 31, 2004 as the Lessee shall
specify by facsimile or telephonic (confirmed in writing) notice to the Owner
Participant, the Indenture Trustee, the Trust, the Owner Trustee, the Pass
Through Trustee, the Policy Provider and the Initial Purchasers, in which case
the Participants will keep their funds available, provided that the notice of
postponement shall be received by each party no later than 4:30 p.m., Chicago
time, on the originally scheduled Closing Date, and the term "Closing Date" as
used in this Agreement shall mean the postponed "Closing Date."

            (b) If the closing fails to occur on the Scheduled Closing Date, the
Indenture Trustee shall promptly return to each Participant that makes funds
available to it in accordance with this Section 2 such funds, together with
interest or income earned thereon.

                                       11
<PAGE>

            (c) If the Closing fails to occur on the Scheduled Closing Date and
funds are not returned to each Participant that made funds available by the
Indenture Trustee as provided by Section 2.7(b) above, the Indenture Trustee
shall, if so instructed by the Lessee in the facsimile or telephonic (confirmed
in writing) notice from the Lessee (which notice shall specify the Specified
Investments 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 the Indenture
Trustee from the Participants 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 Participants that provided such funds. In order to obtain
funds for the payment of the Equipment Cost for the Units on the Closing Date or
to return funds to the Participants pursuant to Section 2.7(b), the Indenture
Trustee is authorized to sell any Specified Investments purchased as aforesaid.
The Indenture Trustee shall not be liable for failure to invest such funds or
for any losses incurred on such investments except for losses resulting from its
own willful misconduct or gross negligence.

            (d) If the Closing fails to occur on the Scheduled Closing Date,
unless the Indenture Trustee returns all funds to the Participants by 2:00 p.m.,
Chicago time, on the Scheduled Closing Date, the Lessee shall reimburse each
Participant that has made funds available pursuant to this Section 2 for the
loss of the use of its funds an amount equal to the excess, if any, of (x)
interest on such funds at the Debt Rate for the period from and including the
Scheduled Closing Date to but excluding the actual Closing Date or, if earlier,
the day on which such Participant's funds are returned if such return is made by
2:00 p.m., Chicago time (or to but excluding the next following Business Day if
such return is not made by such time); provided that with respect to the Owner
Participant such period shall in any case be at least one day, unless the Owner
Participant shall have received, prior to 12:00 noon (Chicago 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), over (y) any amount paid
to such Participant in respect of interest or income earned by the Indenture
Trustee on such funds pursuant to Section 2.7(c) above.

Participant Agreements, and the execution, delivery and performance by it
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
Owner Participant or any of its properties, or contravene the provisions of, or
constitute a default under or breach of, or result in the creation or imposition
of any Lien (other than the Lien granted to the Indenture Trustee under and

<PAGE>

Equipment, Subleases or any other portion of the Trust Estate under, its
certificate of incorporation, bylaws or any indenture, mortgage, contract or
other agreement or instrument to which the Owner Participant is a party or by
which it or any of its properties may be bound or affected;

            (c) the Owner Participant Agreements have been duly authorized by
all necessary actions on the part of the Owner Participant, do not require any
approval not already obtained of the partners of the Owner Participant or any

manner which would violate the Securities Act, but without prejudice, however,
to the right of the Owner Participant at all times to sell or otherwise dispose
of all or any part of such Beneficial Interest in compliance with the Securities
Act and any state securities or "blue sky" laws; provided, however, that subject
to the provisions of Section 6.1, the disposition of the Beneficial Interest

Participant acknowledges that its Beneficial Interest has not been registered
under the Securities Act, and that neither the Owner Participant, the Owner
Trustee, Trust Company, the Lessee, TRLTII nor TILC contemplates filing, or is
legally required to file, any such registration statement; notwithstanding the
foregoing, the Owner Participant makes no representation that the Beneficial
Interest is a "security" within the meaning of such term under the Securities
Act;

            (h) with respect to the source of the amount to be invested by the

will hold TILC, TRLTII, the Lessee, the Indenture Trustee, the Loan Participant
and the Owner Trustee harmless from any claim, demand or liability for broker's
or finder's or placement fees or commission alleged to have been incurred as a
result of any action by the Owner Participant in connection with this
transaction.

      Section 3.6 Representations and Warranties of TILC. TILC represents and
warrants to each of the Trust, the Owner Trustee, the Indenture Trustee, the

            (a) TILC is a corporation duly organized, validly existing, and in
good standing under the laws of the State of Delaware, is duly licensed or
qualified and in good standing in each jurisdiction in which the failure to so

Agreements and the Partnership Documents to which it is or will be a party, has
the power and authority to carry on its business as now conducted and as

Partnership Documents to which it is or will be a party;

            (b) the TILC Agreements have been duly authorized by all necessary
corporate action, executed and delivered by TILC, and (assuming the due
authorization, execution and delivery by each other party thereto) constitute
the legal, valid and binding obligations of TILC, enforceable against TILC 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 TILC of each TILC
Agreement and compliance by TILC with all of the provisions thereof do not and
will not contravene or, in the case of clause (iii), constitute (alone or with
notice, or lapse of time or both) a default under or result in any breach of, or
result in the creation or imposition of any Lien upon any property of TILC
pursuant to, (i) any law or regulation, or any order, judgment, decree,
determination or award of any court or governmental authority or agency
applicable to or binding on TILC or any of its properties, or (ii) the
provisions of its certificate of incorporation or bylaws or (iii) any indenture,
mortgage, contract or other agreement or instrument to which TILC is a party or
by which TILC or any of its properties may be bound or affected except, with
respect to clause (iii), where such contravention, default or breach would not
reasonably be expected to materially adversely affect TILC's ability to perform
its obligations under the TILC

                                       27

            (d) there are no proceedings pending or, to the knowledge of TILC,
threatened against TILC in any court or before any governmental authority or

its property may be bound except in the case of clause (y) where such violation,
breach or default would not reasonably be expected to materially adversely
affect TILC's ability to perform its obligations under the TILC Agreements or
materially adversely affect its financial condition or business. TILC is in
compliance with all laws, ordinances, governmental rules, regulations, orders,
judgments, decrees, determinations and awards to which it is subject, the
failure to comply with which would reasonably be expected to have a material and
adverse effect on its operations or condition, financial or otherwise, or would
impair the ability of TILC to perform its obligations under the TILC Agreements,
and has obtained all required licenses, permits, franchises and other
governmental authorizations material to the conduct of its business;

            (f) no consent, approval or authorization of, or filing,
registration or qualification with, or the giving of notice to, any trustee or

delivery by TILC of the TILC Agreements or any Sublease or Pledged Equipment
Lease to which TILC is a party, or is required to be obtained in order for TILC
to perform its obligations thereunder in accordance with the terms thereof,
other than (i) as may be required under existing laws, ordinances, governmental
rules and regulations to be obtained, given, accomplished or renewed at any time

believe will not be timely obtained or (ii) as may be required under the
Operative Agreements in consequence of any transfer of ownership of the
Equipment or the Pledged Equipment occurring after the Closing Date;

            (g) to the best knowledge of TILC, no casualty event or other event

the Closing Date shall convey to the Lessee, all legal and beneficial title to
the Units which are being delivered on the Closing Date, free and clear of all
Liens (other than Permitted Liens of the type described in clause (ii) below
with respect to the Existing Equipment Subleases, and in clauses (iii), (iv),
(v) and (viii) of the definition thereof), and such conveyance will not be void
or voidable under any applicable law; (ii) TRLTII has, and the TRLTII Assignment

Bill of Sale to be delivered on the Closing Date shall convey to the Lessee, all
legal and beneficial title to the Pledged Units which are being delivered on the

type described in clauses (ii), (iii), (iv) and (v) of the definition thereof),
and such conveyance will not be void or voidable under any applicable law; (v)
TRLTII shall have, and the TRLTII Pledged Equipment Assignment to be delivered

under any applicable law; and (vi) all of the Pledged Units shall be subject to

Lessee pursuant to the TRLTII Bill of Sale and in selecting the Pledged Units to
be sold to the Lessee pursuant to the TRLTII Pledged Equipment Bill of Sale,
TRLTII has not discriminated against the Lessee in a negative fashion when such
Units and Pledged Units are compared with the other equipment in the TILC Fleet;

            (l) the written information provided by TILC or TRLTII or on behalf
of TRLTII in the Offering Circular does not contain any untrue statement of a
material fact and does not omit a material fact necessary to make the statements
contained therein, in light of the circumstances under which they were made, not
misleading; the assumptions and related financial information relating to the
proposed business and operations of TILC and the Equipment which are contained
in the Offering Circular have been prepared in good faith based

                                       29
<PAGE>

upon information that TILC deems fair and reasonable, and there are no
statements or conclusions therein which are based on or include information
known to TILC to be misleading in any material respect or which fail to take
into account material information known to TILC regarding the matters stated
therein; certain information contained in the Offering Circular (e.g.
statistical information relating to renewal and remarketing of railcars,
potential increases in absolute or nominal railcar lease rates, anticipated
utilization, and maintenance costs) is based on the historical experience of

by written notice to the Owner Trustee and the Indenture Trustee not less than
60 days prior to such Determination Date, purchase all of the Equipment for a

documentation relating to such purchase and the costs of any necessary filings
related thereto will be borne by the Lessee.

by reason of any action, suit, claim, proceeding, entry of any judgment or

subject to any claim, action or proceeding asserting a priority interest in such
Affected PPSA Unit as a result of the outstanding filing in favor of the Release
Party or Acknowledgment Party, as applicable (which claim, action or proceeding
is not discharged or dismissed within 90 days), then TILC agrees not later than

PPSA Unit with, or remarket under a new sublease any Affected PPSA Unit to, Nova
(as defined below) or Marsulex (as defined below).

Indemnitee is also a Lender Tax Indemnitee).

            (b) Taxes Indemnified. Except as provided in Section 7.1(c) below,
the Lessee agrees that all payments of Rent pursuant to the Lease and all other
payments made by the Lessee to or for the benefit of any Tax Indemnitee in
connection with the transactions contemplated by the Operative Agreements shall
be free of all withholdings or deductions of any nature whatsoever (and at the
time that any payment is made upon which any withholding or deduction is
required, the Lessee shall pay an additional amount such that the net amount
actually received will, after such withholding or deduction 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. The Lessee shall
defend, indemnify and save harmless each Tax Indemnitee from and against, and as
between the Lessee and each Tax Indemnitee, the Lessee hereby assumes liability
with respect to, on an After-Tax Basis all fees (including, without limitation,
documentation, recording, filing, license and registration fees), taxes
(including, without limitation, those in the nature of net or gross income,
gross receipts, franchise, sales, use, value added, ad valorem, rent, turnover,

any nature whatsoever, together with any and all penalties, additions to tax,
fines or interest thereon and any liabilities, losses, expenses or costs related
thereto (collectively, "Taxes"), which at any time may be levied, assessed or
imposed by the United States federal, any state or local authority or any
foreign governmental authority (or political subdivision thereof) upon, with
respect to, or against any of the Tax Indemnitees, any item of Equipment,
Pledged Equipment, any Sublease, the Lease, any portion of the Collateral, any
Operative Agreement, or any interest in, portion of, or user of, any of the
foregoing, upon, arising from or relating to:

                  (i) any item of the Equipment or the Pledged Equipment, any
Sublease or any portion of the Collateral (including any Account),

                  (ii) the construction, manufacture, financing, acquisition,
purchase, delivery, ownership, acceptance, rejection, possession, improvement,
use, operation, leasing, subleasing, condition, maintenance, repair,

any item of the Equipment or the Pledged Equipment or payable pursuant to the
Operative Agreements, or

                  (iv) the Operative Agreements, the Partnership Documents, the

<PAGE>

to or in connection with the transactions contemplated thereby or the issuance
acquisition, transfer or refinancing of the Equipment Notes.

            (c) Taxes Excluded. The indemnity provided in Section 7.1 (b) shall
not include:

                  (i) as to any Equity Tax Indemnitee, any Income Tax imposed by
the United States federal government (but not excluding any Income Tax required
to make a payment on an After-Tax Basis);

                  (ii) as to any Equity Tax Indemnitee, any Income Tax imposed
by any state, local or foreign government or taxing authority or subdivision
thereof (but not excluding an Income Tax required to make a payment on an
After-Tax Basis); provided, however, that this exclusion shall not apply to the
extent such Taxes relate directly or indirectly to (I) the use, location of any
item of the Equipment or the activities of the Lessee in the taxing
jurisdiction, (II) the presence or organization of the Lessee in the taxing
jurisdiction, (III) any payment by or on behalf of the Lessee being made from
the taxing jurisdiction, or (IV) the execution or delivery of any Operative
Agreement by the Lessee in the taxing jurisdiction; provided, further, however,
that the preceding proviso shall not apply to any Taxes that are solely
attributable to the fact that the Owner Trust, the Owner Trustee (other than in
its individual capacity) or the Owner Participant or any Related Party thereto
has its legal domicile or a principal place of business in the taxing
jurisdiction (determined without regard to the transactions contemplated by the
Operative Agreements or any similar lease transaction between the Owner
Participant and the Lessee or an Affiliate of the Lessee);

                  (iii) as to any Equity Tax Indemnitee, any Tax that is imposed
as a result of the voluntary sale, transfer or other disposition, or any

similar proceeding for relief of debtors in which such Equity Tax Indemnitee is
a debtor, by the Lessor or the Owner Participant of any of its rights with
respect to any item of Equipment or the Owner Participant's interest in the
Trust Estate unless such sale, transfer or other disposition is during the
continuance of a Lease Event of Default or is otherwise pursuant to the Lessor's
exercise of its rights under the Operative Agreements or is as a result of (x)
any substitution, replacement, improvement, modification or addition to the
Equipment or any portion thereof by the Lessee, a Sublessee, or a Related Party
to the Lessee or Sublessee, (y) a requirement of the Lessee in the Operative
Agreements or under applicable law, or (z) a purchase of the Equipment or any
Unit thereof pursuant to the Lease or the other Operative Agreements;

                  (iv) as to any Equity Tax Indemnitee, any Taxes to the extent
they exceed the Taxes that would have been imposed if such Equity Tax Indemnitee
were a U.S. Person;

                  (v) Taxes imposed on a Lender Tax Indemnitee, excluding the
Policy Tax Indemnitee, with respect to any period after the payment in full of
the Equipment Notes; provided that the exclusion set forth in this clause (v)
shall not apply to Taxes to the extent such Taxes (I) relate directly or
indirectly to events occurring or matters arising prior to or simultaneously
with the date on which all of the principal of, interest on and all other
amounts

                                       59
<PAGE>

payable in respect of the Equipment Notes have been paid in full or (II) result

arising prior or simultaneously with the date on which all of the principal of,
interest on and other amounts payable in respect of the Equipment Notes, all
Policy Provider Amounts and all Policy Provider Reimbursement Costs have been
paid in full or (II) result from a Lease Event of Default that has occurred and
is continuing;

                  (vii) as to any Tax Indemnitee, Taxes to the extent caused by
any misrepresentation or breach of warranty or covenant by such Tax Indemnitee
or a Related Party of such Tax Indemnitee under any of the Operative Agreements
(except to the extent such misrepresentations or breach is attributable to any
act or omissions of the Lessee or any sublessee, transferee or assignee of the
Lessee) or by the gross negligence or willful misconduct of such Tax Indemnitee
or such Related Party;

                  (viii) as to any Lender Tax Indemnitee, Taxes that become
payable as a result of a voluntary sale, assignment, transfer or other
disposition, or any involuntary sale, transfer or other disposition resulting
from a bankruptcy or similar proceeding for relief of debtors in which such
Lender Tax Indemnitee is a debtor, by such Lender Tax Indemnitee of all or any
portion of its interest in the Equipment or any part thereof, the Equipment
Notes, the Trust Estate, the Indenture Estate or any of the Operative Agreements
or rights created thereunder; provided, however, that is this clause (viii)
shall not apply in the case of any sale assignment, transfer or other
disposition (whether voluntary of involuntary) which occurs as a result of or
while a Lease Event of Default has occurred and is continuing or which occurs as
a result of (v) the exercise of remedies for a Lease Event of Default, (w) any
substitution, replacement, improvement, modification or addition to the
Equipment or any portion thereof by a Lessee, Sublessee or a Related Party to
the Lessee or Sublessee, (x) a requirement in the Operative Agreements or under
applicable law, (y) a purchase of the Equipment or any Unit thereof pursuant to

result of such Lender Tax Indemnitee not being a U.S. Person;

                  (x) as to any Lender Tax Indemnitee, Income Taxes or transfer
taxes relating to any payments of principal of, interest on or Make Whole Amount
or other amounts in respect thereof, if any, on the Equipment Notes or the Pass
Through Certificates paid to such Tax Indemnitee provided, that this clause (x)
should not be interpreted to prevent any payment from being made on an After-Tax
Basis, and provided further that this clause (x) shall not apply to Taxes
attributable to (I) the use or location of any item of Equipment or the
activities of the Lessee in the taxing jurisdiction, (II) the presence or
organization of the Lessee in the taxing jurisdiction or (III) the execution or
delivery of any Operative Agreement in the taxing jurisdiction; provided,
further, however, the preceding provision shall not apply to any

                                       60
<PAGE>

jurisdiction where such Lender Tax Indemnitee or any Related Party of such
Lender Tax Indemnitee has its legal domicile or a place of business (determined
without regard to the transitions contemplated by the Operative Agreements);

                  (xi) Taxes to the extent directly resulting from or that would
not have been imposed but for (x) in the case of Taxes imposed on or with
respect to any Equity Tax Indemnitee, the existence of any Lessor Liens with
respect to such Equity Tax Indemnitee, or (y) in the case of Taxes imposed on or
with respect to any Lender Tax Indemnitee, the existence of any Liens
attributable to the Indenture Trustee that are unrelated to the transactions
contemplated by the Operative Agreements or Liens attributable to the Pass
Through Trustee that are unrelated to the transactions contemplated by the
Operative Agreements;

                  (xii) Taxes imposed on a Tax Indemnitee to the extent that
such Taxes would not have been imposed upon such Tax Indemnitee but for any
failure of such Tax Indemnitee or a Related Party of such Tax Indemnitee to
comply with (x) any certification, information, documentation, reporting or
other similar requirements concerning the nationality, residence, identity or
connection with the jurisdiction imposing such Taxes, if such compliance is
required under the laws or regulations of such jurisdiction to obtain or
establish relief or exemption from or reduction in such Taxes and the Tax
Indemnitee or such Related Party was eligible to comply with such requirement or
(y) any other certification, information, documentation, reporting or other
similar requirements under the Tax laws or regulations of the jurisdiction
imposing such Taxes that would establish entitlement to otherwise applicable
relief or exemption from such Taxes and the Tax Indemnitee or such Related Party
was eligible to comply with such requirement; provided, however, that the
exclusion set forth in this clause (xii) shall not apply (I) if such failure to
comply was due to a failure of the Lessee to provide such Tax Indemnitee
reasonable assistance on request in complying with such requirement, (II) if in
the good faith judgment of such Tax Indemnitee there is a risk of adverse
consequence to such Tax Indemnitee or any Affiliate from such compliance against
which such Tax Indemnitee is not satisfactorily indemnified, or (III) in the
case of any Tax Indemnitee, unless Lessee shall have given such Tax Indemnitee
prior timely written notice of such requirements;

                  (xiii) as to the Equity Tax Indemnitee, Taxes that are imposed
with respect to any period after both of the following shall have occurred: (x)
the termination of the Lease Term pursuant to Section 6, 10, 11 or 22 of the
Lease (unless the Equipment is thereafter required to be returned, in which
case, after such return) and (y) the payment by the Lessee of all amounts due
and owing by it to the Equity Tax Indemnitee under the Lease and other Operative
Agreements; provided, however, that the exclusion set forth in this clause
(xiii) shall not apply (I) to Taxes to the extent such Taxes relate to events
occurring or matters arising prior to or simultaneously with such return or
termination and (II) so long as a Lease Event of Default has occurred and is
continuing;

                  (xiv) as to any Lender Tax Indemnitee, Taxes in the nature of
an intangible or similar tax upon or with respect to the value of the interest
of such Lender Tax Indemnitee in the Indenture Estate, in any Equipment Note or
Pass Through Certificate imposed as a result of such Lender Tax Indemnitee or
any Affiliate of such Lender Tax Indemnitee being organized in, or conducting
activities unrelated to the contemplated transactions in, the jurisdiction
imposing such Taxes, provided however, that this exclusion shall not apply to
the

                                       61
<PAGE>

incremental amount of such taxes that arise from such Lender Tax Indemnitee's
participation in the transactions contemplated herein;

                  (xv) Taxes imposed on the Owner Trustee, the Pass Through
Trustee or the Indenture Trustee that are on, based on or measured by any
trustee fees for services rendered by such Tax Indemnitee;

                  (xvi) Except as set forth in Section 7.2, Taxes imposed on any
Tax Indemnitee, or any other person who, together with such Tax Indemnitee, is
treated as one employer for employee benefit plan purposes, as a result of, or
in connection with, any "prohibited transaction," within the meaning of the
provisions of the Code or regulations thereunder or as set forth in Section 406
of ERISA or the regulations implementing ERISA or Section 4975 of the Code or
the regulations thereunder;

                  (xvii) Taxes for so long as (x) such Taxes are being contested
in accordance with the provisions of Section 7.1 (e) hereof, (y) the Lessee is
in compliance with its obligations under Section 7.1(e), and (z) the payment of
such Taxes is not required pursuant to Section 7.1(e); provided, however, that
with respect to a Lender Tax Indemnitee this clause (xvii) shall only apply so
long as the non-payment of the contested Tax does not result in any Lender Tax
Indemnitee failing to receive all required payments when due under the Equipment
Notes;

                  (xviii) as to any Equity Tax Indemnitee, Taxes as to which
such Tax Indemnitee is indemnified pursuant to the Tax Indemnity Agreement;

                  (xix) any Taxes imposed on or with respect to any
Certificateholder;

                  (xx) Taxes imposed on a Tax Indemnitee as a result of the
authorization or giving of any future amendments, supplements, waivers or
consents by such Tax Indemnitee with respect to any Operative Agreement other
than (w) in connection with the exercise of remedies pursuant to Section 15 of
the Lease or while a Lease Event of Default has occurred and is continuing, (x)
such as have been proposed by the Lessee or consented to by the Lessee in
writing, (y) those that are required by applicable law or pursuant to the terms
of the Operative Agreements, or (z) those that may be necessary or appropriate
to, and are in conformity with, any amendment, supplement, waiver or consent
proposed by the Lessee or consented to by the Lessee in writing;

                  (xxi) Taxes imposed under Section 6707 or Section 6708 of the
Code or with respect to provisions of state or local law similar to Sections
6707 and 6708 of the Code; provided, however, that this clause (xxi) shall not
apply to any Taxes imposed under Section 6707(a) to the extent such Taxes arise
(x) as a result of the Lessee or any Sublessee providing the Designated
Organizer, (within the meaning of Temporary Treasury Regulation Section
301.6111-1T, Q/A 38 and 39) any false or misleading information or (y) as a
result of the Lessee failing to provide the Designated Organizer or Tax
Indemnitee with any item of information that is required under Section 6111 or
Section 6112 of the Code or the regulations promulgated thereunder, which the
Lessee possesses, that is requested by the Designated Organizer or Tax
Indemnitee from the Lessee; and

                                       62
<PAGE>

                  (xxii) other than as addressed in clause (xxi) of this Section
7.1(c), interest, penalties and additions to tax that would not have been
imposed but for the failure of a Tax Indemnitee to file any required document
timely and properly, except to the extent that such failure is the direct result
of Lessee's breach of its obligations under Section 7.1(g) or of a Lease Event
of Default.

For purposes of this section 7.1(c), any reference to the Lessee shall include
the Lessee and any Related Party of the Lessee. Furthermore, the activities
described in Section 7.1(m) shall not constitute an event described in any of
the exclusions of this Section 7.1(c).

            (d) Payments to Tax Indemnitee. The Lessee agrees to pay, on demand,
any and all Taxes indemnified under this Section 7.1 ("Indemnified Taxes"), and
to keep at all times all and every part of each Unit and Pledged Equipment free
and clear of all Indemnified Taxes which might in any way affect the interest of
any Tax Indemnitee in or result in a Lien upon any such Unit or Pledged
Equipment; provided, however, that the Lessee shall be under no obligation to
pay any Tax so long as either the Tax Indemnitee or the Lessee is contesting
such Tax in good faith, in a manner consistent with this Section 7.1, and by
appropriate legal proceedings.

            Subject to Section 7.1(e), if any Indemnified Taxes shall have been
charged or levied against any Tax Indemnitee directly and paid by such Tax
Indemnitee after such Tax Indemnitee shall have given written notice thereof to
the Lessee and the same shall have remained unpaid for a period of ten Business
Days thereafter, the Lessee shall reimburse such Tax Indemnitee payment.

            (e) Contests. If a written claim is made by any taxing authority
against a Tax Indemnitee for any Taxes with respect to which the Lessee may be
required to indemnify against hereunder or if a Tax Indemnitee shall determine
that any tax to which the Lessee may have an indemnity obligation hereunder may
be payable (a "Tax Claim"), then such Tax Indemnitee shall give the Lessee
written notice of such Tax Claim promptly (but in any event within twenty (20)
days after its receipt of the written Tax Claim or its determination, as
applicable), and shall furnish Lessee with copies of such Tax Claim and all
other writings received from the taxing authority to the extent relating to such
claim (but failure to so notify the Lessee shall not relieve the Lessee of its
obligations hereunder except to the extent that it effectively precludes the
ability of the Lessee to conduct a contest of the Tax Claim). The Tax Indemnitee
shall not pay such Tax Claim until at least thirty (30) days after providing the
Lessee with such written notice, unless (a) the Tax Indemnitee is required to do
so by law or regulation or the failure to pay such Tax Claim could result in a
material adverse financial, legal or other consequence to the Tax Indemnitee and
(b) in the written notice described above, the Tax Indemnitee has notified the
Lessee of such requirement or such material adverse consequence (such notice
however shall not require the disclosure of the Tax Indemnitee's confidential
information, as determined in the sole discretion of such Tax Indemnitee, or the
Tax Indemnitee's tax returns, books, or records). If the Lessee shall so request
within 30 days after receipt of such notice (or such shorter period as is
reasonably specified by the Tax Indemnitee if any contest of the Tax must be
commenced prior to the expiration of 30 days), then such Tax Indemnitee shall in
good faith at Lessee's sole expense contest such Tax or permit the Lessee to
contest such Tax, as such Tax Indemnitee shall elect; provided, however, that to
the extent (i) the contest involves only Taxes constituting property taxes,
sales taxes, or use taxes, (ii) the contest does not involve any taxes that the
Lessee

                                       63
<PAGE>

is not required to indemnify the Tax Indemnitee or taxes and other issues
relating to a Tax Indemnitee that are unrelated to the transactions contemplated
by the Operative Agreements, (iii) the contest can be pursued in the name of the
Lessee and independently from any other proceeding involving a Tax Claim of a
Tax Indemnitee for which Lessee has not agreed in writing to indemnify such Tax
Indemnitee, and (iv) no Equity Insufficiency Circumstance exists, such contest
shall be undertaken by the Lessee at the Lessee's sole expense and the after-tax
costs of the Lessor, the Owner Participant, or other Tax Indemnitee shall be
reimbursed by the Lessee. Notwithstanding the preceding sentence, if (a) such
contest would involve any other type of Tax, any taxes that the Lessee is not
required to indemnify the Tax Indemnitee or taxes and other issues relating to a
Tax Indemnitee which are unrelated to the transactions contemplated by the
Operative Agreements, (b) the Tax Indemnitee determines that such contest
conducted by the Lessee could have a material adverse impact on such Tax
Indemnitee's business or operations or involve risk of the imposition of
criminal liability on a Tax Indemnitee, or (c) an Equity Insufficiency
Circumstance exists, then such Tax Indemnitee may, in its sole discretion,
control such contest (including selecting the forum for such contest, and
determining whether any such contest shall be conducted by (i) paying such Tax
under protest or (ii) resisting payment of such Tax or (iii) paying such Tax and
seeking a refund thereof; provided, however, that at such Tax Indemnitee's
option, such contest shall be conducted by the Lessee in the name of such Tax
Indemnitee). In no event shall such Tax Indemnitee be required or the Lessee be
permitted to contest any Tax for which the Lessee is obligated to indemnify
pursuant to this Section 7.1 unless: (i) the Lessee shall have acknowledged in
writing (x) that it is solely responsible for any Indemnified Tax resulting from
any contest under its control, (y) its liability to such Tax Indemnitee for all
reasonable out of pocket costs, losses and expenses that the Tax Indemnitees may
incur in connection with contesting the Indemnified Tax (including, but not
limited to, any reasonable legal, accounting and investigatory fees and
disbursements), and (z) its liability for an indemnity payment pursuant to this
Section 7.1 as a result of such claim if and to the extent such Tax Indemnitee
or the Lessee, as the case may be, shall not prevail in the contest of such
claim; provided, however, that the Lessee shall not be required to indemnify for
such Taxes to the extent the results of the contest clearly demonstrate that the
Tax is not an Indemnified Tax unless the Lessee's conduct of the contest
materially prejudiced the Tax Indemnitee; (ii) such Tax Indemnitee shall have
received the opinion of independent tax counsel selected by the Tax Indemnitee
and reasonably satisfactory to the Lessee and furnished at the Lessee's sole
expense, opining that a reasonable basis exists for contesting such claim or, in
the event of an appeal of an adverse court or administrative agency decision,
that as a result of a change in law or fact it is more likely than not that an
appellate court or an administrative agency or decision making body with
appellate jurisdiction, as the case may be, will reverse or substantially modify
the adverse determination; (iii) the Lessee shall have agreed to pay such Tax
Indemnitee on demand (and at no after tax costs to the Lessor, the Owner
Participant and any Tax Indemnitee) all reasonable costs and expenses that such
Tax Indemnitee may incur in connection with contesting such claim (including,
without limitation, all reasonable legal and accounting fees and disbursements);
(iv) no Lease Default described in Section 14(a), 14(b), 14(c), 14(g) or 14(h)
of the Lease or a Lease Event of Default shall have occurred and shall have been
continuing, unless the Tax Indemnitee in its sole discretion exercised in good
faith allows the Lessee to post a satisfactory bond or other security that does
not involve a possibility of a Lien on the Equipment or any portion thereof or
on any interest therein, and which bond or other security will be for an amount
equal to the sum of (I) the costs of such contest (as reasonably estimated by
such Tax Indemnitee

                                       64
<PAGE>

in good faith) and the Taxes which may be required to be indemnified and (II) if
such Lease Default or Lease Event of Default involves a payment obligation under
an Operative Agreement that is currently not paid in full, the unpaid amount of
such obligation, plus the present value of the amounts not yet due pursuant to
such obligation; (v) such Tax Indemnitee shall have determined that the action
to be taken will not result in any risk of sale, forfeiture or loss of, or the
creation of any Lien, or the Lessee shall have or otherwise made a provision to
protect the interest of such Tax Indemnitee (in a manner satisfactory to such
Tax Indemnitee in its sole discretion), on the Equipment or any portion thereof
or any interest therein; (vi) the amount of such claims alone, or, if the
subject matter thereof shall be of a continuing or recurring nature, when
aggregated with substantially identical potential claims with respect to the
transactions contemplated by the Operative Agreements shall be at least $25,000;
(vii) if such contest shall be conducted in a manner requiring the payment or
deposit of the claim, the Lessee shall have paid the amount required (and at no
after-tax costs to the Lessor, the Owner Participant or other Tax Indemnitee);
and (viii) there is no risk of imposition of criminal liability or penalties.
The Lessee shall cooperate with the Tax Indemnitee in good faith with respect to
any contest controlled and conducted by the Tax Indemnitee and the Tax
Indemnitee in good faith shall consult with the Lessee regarding the conduct of
such contest. A Tax Indemnitee shall not be required to pursue an appeal to the
U.S. Supreme Court or the highest court in Canada or Mexico. The Tax Indemnitee
shall cooperate 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.

            Notwithstanding anything to the contrary contained in this Section
7.1, no Tax Indemnitee shall be required to contest any claim if the subject
matter thereof shall be of a continuing or recurring nature and shall have
previously been adversely decided to the Tax Indemnitee pursuant to the contest
provisions of this Section 7.1 unless there shall have been a change in the law
(including, without limitation, amendments to statutes or regulations,
administrative rulings (excluding private letter rulings and other rulings or
materials that may not be relied upon by such Tax Indemnitee as precedent) or
court decisions in the applicable jurisdiction) enacted, promulgated or
effective after such claim shall have been so previously decided, and such Tax
Indemnitee shall have received an opinion of independent tax counsel selected by
the Tax Indemnitee and reasonably satisfactory to the Lessee, furnished at the
Lessee's sole expense, to the effect that such change is favorable to the
position which such Tax Indemnitee or the Lessee, as the case may be, had
asserted in such previous contest and as a result of such change, it is more
likely than not that the Tax Indemnitee will prevail or, in the event of an
appeal of an adverse court or administrative agency decision, that it is more
likely than not that an appellate court or an administrative agency tribunal or
decision making body with appellate jurisdiction, as the case may be, will
reverse or substantially modify the adverse determination.

            Notwithstanding anything contained in this Section 7.1, a Tax
Indemnitee will not be required to contest the imposition of any Tax and shall
be permitted to settle or compromise any claim without the Lessee's consent if
such Tax Indemnitee (A) shall waive its right to indemnity under this Section
7.1 with respect to such Tax (and any claim the outcome of which is determined
based upon the outcome of such claim) and (B) shall pay to the Lessee any amount
previously paid or advanced by the Lessee pursuant to this Section 7.1 with
respect to such Tax

                                       65
<PAGE>

Claim, less any reasonable costs and expenses of the Tax Indemnitee prior to
such payment in respect of such Tax Claim.

            (f) Payments to Lessee. With respect to any payment or indemnity
hereunder, such payment or indemnity shall have included an amount payable to
the Tax Indemnitee sufficient to hold such Tax Indemnitee harmless on an
After-Tax Basis from all Taxes required to be paid by such Tax Indemnitee with
respect to such payment or indemnity under the laws of any federal, state or
local government or taxing authority in or of the United States, or under the
laws of any taxing authority or governmental subdivision in or of a foreign
country; provided that, if both (w) any Tax Indemnitee determines in it sole
discretion that is has recognized either (1) a credit or refund of any
Indemnified Tax, or (2) a reduction in Taxes that are not Indemnified Taxes, in
either case as a result of the Lessee's indemnity or payment under this Section
7.1; and (x) such credit, refund or reduction was not taken into account in
computing such payment or indemnity by the Lessee ("Tax Savings"), then such Tax
Indemnitee shall pay to the Lessee an amount equal to the excess of: (y) such
Tax Savings, over (z) the sum of (I) any tax benefit realized by the Lessee as a
result of this payment by such Tax Indemnitee, plus (II) any Taxes imposed on
such Tax Indemnitee by reason of its receipt or accrual of the Lessee's
indemnity or payment; provided further that, (i) if at the time such payment
shall be due to the Lessee, a Lease Event of Default shall have occurred and be
continuing, such amount shall not be payable until such Lease Event of Default
shall have been cured, and (ii) the amount that such Tax Indemnitee shall be
required to pay to the Lessee shall not exceed the amounts that the Lessee has
theretofore paid such Tax Indemnitee under this Section 7.1 with respect to such
indemnity relating to the same Tax Claim, less the amount of all prior payments
made to the Lessee in respect of such indemnity or a substantially identical
indemnity under this section 7.1(f). If it is subsequently determined that the
Tax Indemnitee was not entitled to such tax benefit for which payment was made
to the Lessee hereunder, the amount of such tax benefit that is required to be
repaid or recaptured will be treated as Taxes for which the Lessee must
indemnify the Tax Indemnitee pursuant to this Section 7.1 without regard to
paragraph (c) hereof.

            For purposes of this Section 7.1, in determining the order in which
the consolidated (for federal income tax purposes) group to which such Tax
Indemnitee belongs utilizes withholding or other foreign taxes as a credit
against such group's United States income taxes, such Tax Indemnitee (and such
group) shall be deemed to utilize (i) first, all foreign taxes other than those
described in clauses (ii) and (iii) below; provided, however, that such other
foreign taxes that are carried back to the taxable year for which a
determination is being made pursuant to such clause (i) shall be deemed utilized
after the foreign taxes described in clause (ii) below, (ii) then, on a pari
passu basis, the foreign taxes indemnified hereunder together with all other
foreign taxes (including fees, taxes and other charges hereunder) with respect
to which such Tax Indemnitee (or any member of such group) is entitled to obtain
indemnification pursuant to an indemnification provision contained in any lease,
loan agreement, financing document or participation agreement (including,
without limitation, this Agreement) pursuant to which there is an agreement that
foreign taxes shall be, or shall be deemed to be, utilized on a basis no less
favorable to the indemnitor than those contemplated in this paragraph, and (iii)
third, foreign taxes attributable to transactions entered into by such Tax
Indemnitee (or any member of such group) that did not provide for foreign taxes
to be utilized or deemed utilized on at least a pari passu basis.

                                       66
<PAGE>

            (g) Reports. In the event any reports, returns or statements ("Tax
Reports") are required to be filed with respect to Indemnified Taxes, or
otherwise materially impact a Tax Indemnitee in respect of a Tax, the Lessee
will notify the Tax Indemnitee in writing of such requirement not later than 30
days prior to the date such Tax Reports are required to be filed (determined
without regard to extensions), and will either prepare and timely file such Tax
Reports (in the manner required by applicable law or regulation and in the case
of Tax Reports which are required to be filed on the basis of individual Units,
such reports shall be prepared and filed in such manner as to show, if required,
the interest of each Tax Indemnitee in such Units) and send a copy thereof to
the Tax Indemnitee or, if so directed by the Tax Indemnitee or if it shall not
be permitted to file the same, it will notify each Tax Indemnitee of such
reporting requirements, prepare such reports in such manner as shall be
satisfactory to each Tax Indemnitee and deliver the same to each Tax Indemnitee
within a reasonable period prior, and in no event later than 20 Business Days
prior to, to the date the same is to be filed. The Lessee shall provide, at its
expense, such information as the Owner Participant, the Lessor or other Tax
Indemnitee may reasonably require and request from the Lessee to enable the
appropriate Tax Indemnitees to fulfill their respective tax filing, tax audit,
tax litigation and other tax related obligations.

            (h) Survival. In the event that, during the continuance of this
Agreement, any Indemnified Tax accrues, becomes payable or is levied or assessed
(or is attributable to the period of time during which the Lease is in existence
or prior to the return of Equipment in accordance with the provisions of the
Lease) which the Lessee is or will be obligated to pay or reimburse, pursuant to
this Section 7.1, such liability shall continue, notwithstanding the expiration
or termination of the Lease, until all such Taxes are paid or reimbursed by the
Lessee.

            (i) Affiliated Group. For purposes of applying this Section 7.1 with
respect to any Tax, the term "Owner Participant" shall include each member of
the affiliated group of corporations with which the Owner Participant (and its
successors and assigns) files consolidated or combined tax returns relating to
such Imposition. The term "Lender" shall include any combined, consolidated or
affiliated group (and any member thereof) of which such Person is or shall
become a member if combined, unitary or consolidated returns are or shall be
filed for such affiliated group for United States federal, state or local tax
purposes.

            (j) [Reserved].

            (k) Income Tax. For purposes of this Section 7.1, the term "Income
Tax" means any Tax based on or measured by or with respect to gross income (in
lieu of net income) or net income (including without limitation, capital gains
taxes, personal holding company taxes, minimum taxes and tax preferences) or
gross receipts (in lieu of net receipts) or net receipts and Taxes that 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 Taxes that are, or are in the nature of, sales, use,
rental, excise, ad valorem, stamp, transfer, license, value added, or property
(whether tangible or intangible) taxes shall not constitute an Income Tax).

            (l) Certain Withholding. If the Indenture Trustee or Pass Through
Trustee fails to withhold any Tax required to be withheld with respect to any
payment to a Lender Tax

                                       67
<PAGE>

Indemnitee or any claim is otherwise asserted by a taxing authority against the
Equity Tax Indemnitee for or on account of any amount required to be withheld
from any payment to a Lender Tax Indemnitee or Certificateholder, then the
Lessee will indemnify such Equity Tax Indemnitee (without regard to any
exclusions in Section 7.1(c) hereof) on an After-Tax Basis against any Taxes
required to be withheld and any interest, penalties, and additions to tax with
respect thereto, along with other costs (including attorneys' fees) incurred in
connection with 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, the Trust Estate or the Lessee) shall indemnify the Lessee on
an After-Tax Basis for any payment the Lessee shall have made pursuant to the
preceding sentence.

            (m) Trust Tax Ownership Structure. The Owner Participant hereby
agrees that by December 31, 2005, it shall take all reasonable actions permitted
under applicable law (including, but not limited to creating new entities) to
restructure and hold its beneficial interest in the Trust through a limited
partnership that is disregarded for federal income tax purposes in order to
minimize Texas franchise taxes, if any, imposed on it or any other Equity Tax
Indemnitee as a result of the transactions contemplated herein and for which any
indemnity for such taxes under this Section 7.1 would be owed. The Owner
Participant further agrees to the extent a change in Texas law eliminates the
ability to reduce Texas franchise taxes through a limited partnership structure,
the Owner Participant shall take such reasonable steps to mitigate the Texas
franchise taxes as the result of the change in law, so long as the Owner
Participant determines in its sole discretion that such steps will not have a
material adverse effect on the Owner Participant or any of its Affiliates. The
Lessee shall reimburse the Owner Participant for (x) the costs of any actions
taken pursuant to, or to accomplish the intention of, this Section 7.1(m),
including any taxes attributable to such actions, and (y) any and all Texas
taxes that relate directly or indirectly to the transactions contemplated by the
Operative Agreements, Pass Through Documents or Partnership Documents, in each
case on an After-Tax Basis and without regard to the exclusions in Section
7.1(c) hereof, provided, however that for the avoidance of doubt,
nothwithstanding any provision herein, the Lessee shall not be required to
indemnify the Owner Participant or any of its Affiliates for any such taxes that
would have been imposed on the Owner Participant or any of its Affiliates
without regard to the transactions contemplated by the Operative Agreements,
Pass Through Documents or Partnership Documents. Notwithstanding any other
provision hereto or under any other Operative Agreement, the other parties to
this Agreement hereby agree and consent to the Owner Participant taking the
actions specified in the first and second sentences of this Section 7.1(m).

      Section 7.2 General Indemnification.

            (a) Claims Defined. For the purposes of Sections 7.2 and 7.3,
"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) (including, without limitation, Claims and Taxes arising
out of, or in connection with ERISA, Section 4975 of the Code or provisions
under any federal, state or local authority or any foreign governmental
authority (or political subdivision thereof) that contains one or more
provisions that are similar to Section 406 of ERISA or Section 4975 of the Code
("Similar Laws")) that may be imposed on, incurred by, suffered by, or asserted
against an Indemnified Person, any Unit or any Pledged Unit or other Collateral
and, except as otherwise

                                       68
<PAGE>

expressly provided in Section 7.2 and 7.3, 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 Sections 7.2 and
7.3, "Indemnified Person" means the Owner Participant, the Owner Trustee, Trust
Company, the Indenture Trustee, both in its individual capacity and as trustee,
the Pass Through Trustee, the Policy Provider, each of the Affiliates and each
of the respective directors, officers, employees, successors and permitted
assigns, agents and servants of the foregoing, 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, Trust Company, the Indenture Trustee, the Pass Through Trustee, the
Policy Provider and each of their Affiliates, as applicable, together with the
Owner Participant, the Owner Trustee, Trust Company, 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, the Pass Through Trustee
and the Trust Company, respectively).

            (c) Claims Indemnified. Whether or not any Unit is accepted under
the Lease, or the Closing occurs, and subject to the exclusions stated in
Section 7.2(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 but subject to Section 7.2(g)):

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

in compliance with the terms of the Lease or the Collateral Agency Agreement, as
applicable, or any of the commodities, items or materials from time to time
contained in any Unit or Pledged Unit, whether or not in compliance with the
terms of the Lease or the Collateral Agency Agreement, as applicable, or the
inadequacy of any Unit or Pledged Unit or deficiency or defect in any Unit or
Pledged Unit or any other circumstances in connection with any Unit or Pledged
Unit or the performance of any Unit or Pledged Unit or any risks relating
thereto;

                  (ii) the construction, manufacture, financing, refinancing,
design, purchase, acceptance, rejection, delivery, non-delivery or condition of
any Unit or any Pledged

                                       69
<PAGE>

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, the Lessee or any Affiliate of the Lessee under any of the
Operative Agreements or Partnership Documents, or the falsity of any
representation, warranty or certification of the Lessee or any Affiliate of the
Lessee in any of the Operative Agreements or Partnership Documents to which it
is a party or in any document or certificate delivered by the Lessee or any
Affiliate of the Lessee in connection therewith other than representations and
warranties in the Tax Indemnity Agreement;

Lessee or any Affiliate of Lessee or any Sublessee or any Pledged Equipment
Lessee or any of their respective directors, officers, employees, agents or
servants.

            (d) Claims Excluded. The following are excluded from the Lessee's
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 (and not attributable to events that have
occurred or conditions existing prior to) (A) in the case of the consummation by
the Lessee of a purchase option under Section 22.1 or 22.3 of the Lease or the
occurrence of an Event of Loss with respect to such Unit under Section 11 of the
Lease, the later to occur of (x) the payment of all amounts due from the Lessee
in connection with any such event and (y) the release of the Lien of the
Indenture on such Unit or (B) in all other cases, 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, (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 of
the Lease, the date of return thereof for the purpose of this clause (i) 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 or any loss of tax benefits or
increases in tax liability (provided that this clause (ii) shall not preclude a
Claim from being paid on an After-Tax Basis), but not excluding Taxes or any
loss of tax benefits or increases in tax liability with respect to any
Indemnified Person, or any other person who, together with such Indemnified
Person, is treated as one employer for employee benefit plan purposes, as a
result of, or in connection with, any "prohibited transaction" within the
meaning of the provisions of the Code or regulations thereunder or as set forth
in Section 406 of ERISA or the regulations implementing ERISA, Section 4975 of
the Code or the regulations thereunder or applicable Similar Laws or the
regulations thereunder;

<PAGE>

                  (iii) with respect to any particular Indemnified Person,
Claims resulting from the gross negligence or willful misconduct of such
Indemnified Person or a Related Party of such Indemnified Person (other than
gross negligence or willful misconduct imputed as a matter of law to such
Indemnified Person solely by reason of its interest in the Equipment), or any
breach of any covenant, or falsity of any representation or warranty of such
Indemnified Person or such Related Party;

                  (iv) Claims 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
(x) any such transfer in connection with a Lease Event of Default or the
exercise of remedies in connection therewith and (y) any such transfer to the
Lessee or its designee in connection with a purchase or a voluntary termination
as contemplated by the Lease or Section 6.9 or (z) any such transfer made
pursuant to Section 7.1(m);

                  (v) with respect to any particular Indemnified Person that is

transfer is required by the terms of the Operative Agreements or occurs during
the continuance of a Lease Event of Default, Claims relating to any offer, sale,

in the Equipment Notes or the collateral therefor;

                  (vi) with respect to any particular Indemnified Person, Claims

permitted) attributable to such Indemnified Person or a Related Party of such
Indemnified Person;

                  (vii) with respect to any particular Indemnified Person,
Claims to the extent the risk thereof has been expressly assumed by such
Indemnified Person in connection with the exercise by such Indemnified Person of
any inspection rights under the Operative Documents;

                  (viii) Claims relating to any amount that constitutes or (in

premium on the Equipment Notes or securities issued by the Pass Through Trusts
(except to the extent such amounts are otherwise indemnified pursuant to Section
7.2(c)(iv)); (B) Transaction Costs (without limiting Lessee's obligations under
Sections 2.5(c) and 2.5(e)); (C) ordinary and usual operating or overhead
expenses of the applicable Indemnified Person; (D) Indenture Events of Default

respectively, to distribute any amounts held by it in accordance with the
Operative Agreements; and

                  (ix) Claims relating to the authorization or giving or
withholding of any future amendments, supplements, waivers or consents with
respect to any of the Operative Agreements which are not (1) requested by the
Lessee or (2) required by any applicable law or regulation (other than laws or
regulations solely relating to the business of the Lessor, the

                                       71
<PAGE>

Indenture Trustee, the Trust Company, the Pass Through Trustee, the Initial
Purchasers, the Collateral Agent, the Policy Provider or any Participant) or (3)
entered into in connection with, or as a result of, a Lease Default or (4)
required pursuant to the terms of the Operative Agreements (including such
reasonable expenses incurred in connection with any adjustment pursuant to
Section 2.6).

            (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 applicable insurers in the
exercise of their rights to investigate, defend, settle 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 (but only if neither the Lessee nor TILC shall have actual
knowledge of such Claim) to the extent that failure to give notice of any
action, suit or proceeding against such Indemnified Person shall have a material
adverse effect on Lessee's ability to defend such Claim or recover proceeds
under any insurance policies maintained by the Lessee or to the extent Lessee's
indemnification obligations are increased as a demonstrable result of such
failure. The Lessee shall, after obtaining knowledge thereof, promptly notify
each Indemnified Person of any indemnified Claim affecting such Indemnified
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 confirm to such Indemnified Person Lessee's obligations to
indemnify hereunder for such Claim, 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. To the
extent that a Claim is made against Lessee pursuant to this Section 7.2 at a
time when an identical claim for indemnification arising from substantially
similar facts and circumstances is being asserted against TILC or TRLTII
pursuant to this Section 7, if Lessee is entitled to control the defense of such
Claim pursuant to this Section 7.2 and at the same time TILC or TRLTII, as the
case may be, is entitled to control the defense of such claim or liability
pursuant to this Section 7, Lessee's indemnification obligations under this
Section 7.2 shall not be reduced as a result of the inability of Lessee to
control the defense of such Claim where such inability to control the defense of
such Claim is caused by the exercise by TILC or TRLTII, as applicable, of such
Person's right to control the defense of such indemnified claim as provided by
this Section 7.

            Notwithstanding any of the foregoing to the contrary, the Lessee
shall not be entitled to control and assume responsibility for the defense of
any Claim if (1) a Lease 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 that is adequately bonded to the satisfaction of such
Indemnified Person) on, any Unit, Pledged Unit, Sublease, Pledged Equipment
Lease or Applicable Sublease Payment or Applicable Railcar Payment (each as
defined in the Management Agreement), (3) 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, (4) such Claim involves the
possibility of criminal sanctions or liability to such Indemnified Person, (5)
an Equity Insufficiency Circumstance shall exist or (6) such proceeding involves
Claims not fully indemnified by the Lessee. In the circumstances described in
clauses (1) - (6), 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
reasonable manner that is not likely to materially interfere with such control
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 the 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. The Lessee
may in any event participate in all such proceedings at its own cost; provided
that if Lessee is not entitled to control the defense of such Claim in
accordance with this Section 7.2(f), any participation of the Lessee in such
proceeding shall be in a reasonable manner that is not likely to materially
interfere with the control of the Indemnified Person in such proceeding. 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. No Indemnified Person shall enter into
any settlement or other compromise with respect to any Claim without the prior
written consent of the Lessee unless the Indemnified Person waives its rights to
indemnification hereunder; provided that an Indemnified Person shall be
permitted to enter into such a settlement or compromise without the consent of
the Lessee and without waiving its indemnification rights hereunder if (x) such
Indemnified Person has given the Lessee reasonable prior notice of its intention
to settle or compromise such Claim (the reasonableness of its prior notice to
take into account, among other items, any applicable deadlines in any
proceedings relating to such Claim), (y) the Lessee has not acknowledged its
indemnity obligations with respect to such Claim and (z) there is a significant
risk that an adverse judgment will be entered into against such Indemnified
Person with respect to such Claim.

            In the event that in the course of the investigation or defense of a
Claim, the Lessee shall in good faith reasonably determine that it is not liable
for indemnification with respect thereto under this Section 7.2, it may give
notice to the applicable Indemnified Person of such fact; and, in such case, any
acknowledgment theretofore made by the Lessee of liability with respect to such
Claim under this Section 7.2 shall be deemed revoked and the Lessee may
thereupon cease to defend such Claim; provided that (i) the Lessee shall have
given the Indemnified Person reasonable prior notice of its intention to
renounce such acknowledgment, (ii) the Lessee's conduct regarding the defense of
such Claim or any decision to withdraw from such defense shall not prejudice or
have prejudiced the Indemnified Person's ability to contest such Claim (taking
into account, among other things, the timing of the Lessee's withdrawal and the
theory or theories upon which Lessee shall have based its defense), and (iii)
the Lessee shall have given such Indemnified Person all materials, documents and
records relating to its defense of such Claim as such Indemnified Person shall
have reasonably requested in connection with the assumption by such Indemnified
Person of the defense of such Claim at the cost and expense of the Lessee. In
the event that the Lessee shall cease to defend any Claim pursuant to the
preceding sentence, the Lessee shall indemnify each Indemnified Person, without
regard to any exclusion that might otherwise apply hereunder, to the extent that
the actions of the Lessee in defending

                                       73
<PAGE>

such Claim or the manner or time of the Lessee's election to withdraw from the
defense of such Claim shall have caused such Indemnified Person to incur any
loss, cost, liability, expense or other Claim that such Indemnified Person would
not have incurred had the Lessee not ceased to defend such Claim in such manner
or such time.

            (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. 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; provided, however, so long as a Lease Event of Default
shall have occurred and be continuing, such amount may be held by the Collateral
Agent as security for the Lessee's obligations under the Lease and the other
Operative Agreements; provided, further, only with respect to the Owner
Participant and its Related Indemnitee Group, so long as an event referred to in
clause (5) of Section 7.2(f) hereof shall have occurred and be continuing, such
amount may be held by the Owner Trustee as security for the Lessee's obligations
with respect to the Equity Insufficiency Circumstance.

      Section 7.3 Indemnification by TILC.

            (a) Claims Indemnified. Whether or not any Unit is accepted under
the Lease, or the Closing occurs, and subject to the exclusions stated in
Section 7.3(b) below, TILC 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 but subject to Section 7.3(d)):

                  (i) any breach of or any inaccuracy in any representation,
warranty or certification made by TILC in this Agreement or any of the other
Operative Agreements or in any document or certificate delivered by TILC
pursuant hereto or thereto;

                  (ii) any breach of or failure by TILC to perform any covenant
or obligation of TILC set out in or contemplated by this Agreement or any of the
other Operative Agreements; and

                  (iii) any violation of any law, rule, regulation or order by
TILC or its directors, officers, employees, agents or servants.

            (b) Claims Excluded. The following are excluded from TILC's
agreement to indemnify under this Section 7.3:

                  (i) Claims attributable to acts or events occurring after the
termination of the Lease or the expiration of the Lease Term; and

                                       74
<PAGE>

                  (ii) Claims which are Taxes or any loss of tax benefits or
increases in tax liability (provided that this clause (ii) shall not preclude a
Claim from being paid on an After-Tax Basis);

            (c) Claims Procedure. An Indemnified Person shall, after obtaining
knowledge thereof, promptly notify TILC of any Claim as to which indemnification
is sought; provided, however, that the failure to give such notice shall not
release TILC from any of its obligations under this Section 7.3, except (but
only if neither the Lessee nor TILC shall have actual knowledge of such Claim)
to the extent that failure to give notice of any action, suit or proceeding
against such Indemnified Person shall have a material adverse effect on TILC's
ability to defend such Claim or recover proceeds under any insurance policies
maintained by TILC or to the extent TILC's indemnification obligations are
increased as a demonstrable result of such failure. TILC shall, after obtaining
knowledge thereof, promptly notify each Indemnified Person of any indemnified
Claim affecting such Indemnified Person. Subject to the provisions of the
following paragraph, TILC 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 TILC shall confirm to such Indemnified Person TILC's
obligations to indemnify hereunder for such Claim, 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. To the extent that a Claim is made against TILC pursuant to this
Section 7.3 at a time when an identical claim for indemnification arising from
substantially similar facts and circumstances is being asserted against Lessee
or TRLTII pursuant to this Section 7, if TILC is entitled to control the defense
of such Claim pursuant to this Section 7.3 and at the same time Lessee or
TRLTII, as the case may be, is entitled to control the defense of such claim or
liability pursuant to this Section 7, TILC's indemnification obligations under
this Section 7.3 shall not be reduced as a result of the inability of TILC to
control the defense of such Claim where such inability to control the defense of
such Claim is caused by the exercise by Lessee or TRLTII, as applicable, of such
Person's right to control the defense of such indemnified claim as provided by
this Section 7.

            Notwithstanding any of the foregoing to the contrary, TILC shall not
be entitled to control and assume responsibility for the defense of any Claim 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 or Pledged Unit, (3) 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, (4) such Claim involves the possibility of criminal
sanctions or liability to such Indemnified Person or (5) an Equity Insufficiency
Circumstance shall exist. 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 TILC. In addition,
any Indemnified Person may participate in any reasonable manner that is not
likely to materially interfere with such control in any proceeding controlled by
TILC pursuant to this Section 7.3, at its own expense, in respect of any such
proceeding as to which TILC shall have acknowledged in writing its obligation to
indemnify the Indemnified Person pursuant to this Section 7.3, and at the
expense of TILC in respect of any such proceeding as to which TILC shall not
have so acknowledged its obligation

                                       75
<PAGE>

to the Indemnified Person pursuant to this Section 7.3. TILC may in any event
participate in all such proceedings at its own cost; provided that if TILC is
not entitled to control the defense of such Claim in accordance with this
Section 7.3(c), any participation of the TILC in such proceeding shall be in a
reasonable manner that is not likely to materially interfere with the control of
the Indemnified Person in such proceeding. Nothing contained in this Section
7.3(c) 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. No Indemnified Person shall enter into any settlement or other
compromise with respect to any Claim without the prior written consent of TILC
unless the Indemnified Person waives its rights to indemnification hereunder;
provided that an Indemnified Person shall be permitted to enter into such a
settlement or compromise without the consent of TILC and without waiving its
indemnification rights hereunder if (x) such Indemnified Person has given TILC
reasonable prior notice of its intention to settle or compromise such Claim (the
reasonableness of its prior notice to take into account, among other items, any
applicable deadlines in any proceedings relating to such Claim), (y) TILC has
not acknowledged its indemnity obligations with respect to such Claim and (z)
there is a significant risk that an adverse judgment will be entered into
against such Indemnified Person with respect to such Claim.

            In the event that in the course of the investigation or defense of a
Claim, TILC shall in good faith reasonably determine that it is not liable for
indemnification with respect thereto under this Section 7.2, it may give notice
to the applicable Indemnified Person of such fact; and, in such case, any
acknowledgment theretofore made by TILC of liability with respect to such Claim
under this Section 7.2 shall be deemed revoked and TILC may thereupon cease to
defend such Claim; provided that (i) TILC shall have given the Indemnified
Person reasonable prior notice of its intention to renounce such acknowledgment,
(ii) TILC's conduct regarding the defense of such Claim or any decision to
withdraw from such defense shall not prejudice or have prejudiced the
Indemnified Person's ability to contest such Claim (taking into account, among
other things, the timing of TILC's withdrawal and the theory or theories upon
which TILC shall have based its defense), and (iii) TILC shall have given such
Indemnified Person all materials, documents and records relating to its defense
of such Claim as such Indemnified Person shall have reasonably requested in
connection with the assumption by such Indemnified Person of the defense of such
Claim at the cost and expense of TILC. In the event that TILC shall cease to
defend any Claim pursuant to the preceding sentence, TILC shall indemnify each
Indemnified Person, without regard to any exclusion that might otherwise apply
hereunder, to the extent that the actions of TILC in defending such Claim or the
manner or time of TILC's election to withdraw from the defense of such Claim
shall have caused such Indemnified Person to incur any loss, cost, liability,
expense or other Claim that such Indemnified Person would not have incurred had
TILC not ceased to defend such Claim in such manner or such time.

            (d) Subrogation. If a Claim indemnified by TILC under this Section
7.3 is paid in full by TILC and/or an insurer under a policy of insurance
maintained by TILC, TILC 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. Should an Indemnified Person
receive any refund, in whole or in part, with respect to any Claim paid by TILC
hereunder, it shall promptly pay over the amount refunded (but not in excess of
the amount TILC or any of its insurers has

                                       76
<PAGE>

paid) to TILC; provided, however, so long as a Lease Event of Default shall have
occurred and be continuing, such amount may be held by the Collateral Agent as
security for TILC's obligations under the Lease and the other Operative
Agreements; provided, further, only with respect to the Owner Participant and
its Related Indemnitee Group, so long as an event referred to in clause (5) of
Section 7.3(c) hereof shall have occurred and be continuing, such amount may be
held by the Owner Trustee as security for the Lessee's obligations with respect
to the Equity Insufficiency Circumstance.

      Section 7.4 Special Indemnification Regarding Exercise of Setoff by
Customers. TILC hereby agrees, for the benefit of the Owner Participant, the
Policy Provider, the holders of the Equipment Notes, the Trust Estate and the
Indenture Estate, that it will, within 45 days after the date on which it has
knowledge that any Customer shall have reduced any payments made by such
Customer under any Sublease or Pledged Equipment Lease as a result of or in
connection with any setoff exercised by such Customer (regardless of whether
such Customer actually has any contractual, statutory or other right to exercise
such setoff) with respect to amounts owed or presumed owed to such Customer
pursuant to railcar subleases or leases not constituting Subleases or Pledged
Equipment Leases, and provided that the applicable Customer shall not have made
payments aggregating the full amount payable by such Customer under the
applicable Sublease or Pledged Equipment Lease prior to the end of such 30-day
period, deposit into the Collection Account an amount, in immediately available
funds, equal to the amount of such reduction.

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 it shall not take or cause to be taken any action
contrary to the Lessee's rights under the Lease, including, without limitation,
the right to possession, use and quiet enjoyment (i) by the Lessee of the
Equipment, so long as no Lease Event of Default has occurred and is continuing,
or (ii) to the extent required under the applicable Sublease or Pledged
Equipment Lease or under any applicable consent referred to in Section 4.1(cc)
by any Sublessee of the Equipment or by any Pledged Equipment Lessee of the
Pledged Equipment.

SECTION 9. SUCCESSOR INDENTURE TRUSTEE.

      In the event that the Indenture Trustee gives notice of its resignation
pursuant to Section 8.2 of the Indenture, the Owner Trustee shall promptly
appoint a successor Indenture Trustee reasonably acceptable to the Lessee.

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
Indenture) that it shall not unreasonably withhold its consent to any consent
requested by the Lessee, TILC, TRLTII, the Owner Trustee, the Pass Through
Trustee or the Indenture Trustee, as the case may be, under the

                                       77
<PAGE>

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 Event of Default has
occurred and is continuing, the Lessee shall have the right, on no more than two
occasions, in its sole discretion, at any time following the fifth anniversary
of the Closing Date, to request the Owner Participant and the Trust to effect an
optional prepayment of all, but 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, provided that the Lessee shall obtain the prior written
consent of the Owner Participant to be granted in the sole discretion of the
Owner Participant acting in good faith if such refinancing imposes any increased
risk or liability on or otherwise adversely affects the Owner Participant;
provided further, that the Owner Participant shall not withhold such consent if
in its sole judgment (i) any increased risk or liability is both remote and not
material, (ii) the Lessee and Trinity are at the time at least as creditworthy
as on the Closing Date and (iii) the Lessee provides an indemnity, in form and
substance satisfactory to the Owner Participant, for such increased risk or
liability, which indemnity is guaranteed by Trinity pursuant to a Guaranty
substantially in the form of Section 11 of this Agreement. As soon as
practicable after receipt of such request, the Owner Participant and the Lessee
shall cooperate in good faith to effectuate such refinancing or refunding and
shall enter into an agreement, in form and substance 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 or a securities purchase agreement in connection with a Rule
144A offering), in form and substance reasonably satisfactory to the parties
thereto, providing for (i) the issuance and sale by the Trust 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 (in either case, by
more than six months) the Remaining Weighted Average Life of said Equipment
Notes, (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 Trust 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,
Stipulated Loss Amount, Early Purchase Price, Termination Value and

                                       78
<PAGE>

Termination Amount 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 Trust will enter into an agreement to provide for the
securing thereunder of the debt securities issued by the Trust 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; 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) and the lead in paragraph
of this Section 10.2 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 except
to the extent adversely affecting cash flow, coverage ratios and reserve
accounts, to the extent that they are passed through to the Lessee in, or define
rights or obligations of the Lessee under, the Operative Agreements;

            (d) (i) in the case of a refunding or refinancing involving a public
offering of debt securities, neither the Trust 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 (ii) the Lessee shall
provide satisfactory indemnity to the Owner Trustee and Owner Participant with
respect to the refunding or refinancing;

            (e) unless otherwise agreed by each of the Owner Participant and the
Policy Provider, the Lessee shall pay to the Trust as Supplemental Rent an
amount, on an After-Tax Basis, equal to any Make-Whole Amount, Late Payment
Premium, if any, payable in respect of Equipment Notes outstanding on the
Refunding Date pursuant to the Indenture, all interest which is accrued and
unpaid in respect of late payments of Basic Rent or any part thereof, all Policy
Provider Amounts due and owing to the Policy Provider on the Refunding Date
(after giving effect to the transactions contemplated to occur 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 and
the reasonable fees of any financial advisors);

            (f) the Lessee shall give the Indenture Trustee, the Policy
Provider, the Pass Through Trustee and the Owner Participant not less than 25
days prior written notice of the Refunding Date;

            (g) the Owner Participant, the Owner Trustee, the Pass Through
Trustee and the Indenture 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 reasonably satisfactory to them, as

                                       79
<PAGE>

they may reasonably request in connection with compliance with the terms and
conditions of this Section 10.2 (including with respect to the Owner Participant
a satisfactory tax opinion to the effect that there are no material adverse tax
consequences as a result of the refinancing); and

            (h) such refinancing shall not violate any requirement of law, and
all necessary authorizations, approvals and consents shall have been obtained
and shall be in full force and effect.

            The Lessee shall pay to or reimburse the Participants, the Owner
Trustee and the Indenture Trustee for (A) all costs and expenses (including
reasonable attorneys' and accountants' fees) paid or incurred by them in
connection with such refunding or refinancing and (B) a refunding fee payable to
each Owner Participant on a pro rata basis upon the occurrence of the second
refunding or refinancing equal to the product of $1,000 multiplied by a
fraction, the numerator of which is the total Equipment Cost of the Units on the
date of such refinancing and the denominator of which is $1,000,000.

      Section 10.3 Amendments and Waivers. 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 the
Lessee, TILC, TRLTII, Trinity, the Policy Provider (so long as it is the Control
Party) and each party against which enforcement of the termination, amendment or
waiver is sought.

      Section 10.4 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, and any such notice shall become effective (i) upon
personal delivery thereof, including, without limitation, by reputable overnight
courier, or (ii) in the case of notice by facsimile, upon confirmation of
receipt thereof, provided such transmission is promptly further confirmed by any
of the methods set forth in clause (i) above, in each case addressed to each
party hereto at its address set forth below or, in the case of any such party

provision or the remaining provisions of this Agreement.

      Section 10.11 Counterparts. This Agreement may be executed in any number

      Section 10.12 Headings and Table of Contents. The headings of the Sections

      Section 10.13 Limitations of Liability; Extent of Interest.

            (a) Liabilities of Participants. Neither the Indenture Trustee, the
Owner Trustee nor any Participant shall have any obligation or duty to the
Lessee, to TILC, 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's
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 or TILC for any action or inaction on the
part of the Owner Trustee in connection with the transactions contemplated
herein,

                                       83
<PAGE>

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 action or inaction is expressly prohibited hereby.

            (b) No Recourse to the Owner Trustee. It is expressly understood and
agreed by and between Trust Company, the Owner Trustee, the Lessee, the Owner
Participant, the Indenture Trustee, the Pass Through 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) Trust Company shall not be
liable 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
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.

            (c) Extent of Interest of Holders of Equipment Notes. No holder of
an Equipment Note shall have any further interest in, or other right with
respect to, the mortgage and security interests created by the Indenture when
and if the principal of and interest on all Equipment Notes held by such holder
and all other sums payable to such holder hereunder, under the Indenture and
under such Equipment Notes shall have been paid in full. Each holder of the
Equipment Notes by its acceptance of an Equipment Note, agrees that it will look
solely to the income and proceeds from the Indenture Estate to the extent
available for distribution to such holder as provided in Article III of the
Indenture and that neither TILC, the Lessee, the Owner Participant, the
Indenture Trustee nor the Owner Trustee shall be personally liable to any holder
of the Equipment Notes for any amounts payable under the Equipment Notes, the
Indenture or hereunder, except as expressly provided in the Operative
Agreements.

            (d) Loan Participant's Source of Funds. It is expressly understood
and agreed by and between the Owner Trustee, the Lessee, the Owner Participant,
the Indenture Trustee, the Pass Through Trustee and the Loan Participant, and
their respective successors and permitted assigns that, subject to the proviso
contained in this Section 10.13(d), the undertakings of the Loan Participant
hereunder are limited to the application of the proceeds of the sale of the Pass
Through Certificates to the purchase by the Pass Through Trustee of the
Equipment Notes; provided, however, that nothing in this Section 10.13(d) shall
be construed to limit in scope or substance those representations and warranties
of the Loan Participant made expressly in its individual capacity set forth
herein.

      Section 10.14 Maintenance of Non-Recourse Debt. The parties hereto agree
that if the Trust becomes a debtor subject to the reorganization provisions of
the Bankruptcy Code, 11 U.S.C. Section 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 Trust becomes a debtor
subject to the reorganization provisions of the Bankruptcy Code or any successor
provision, (b) pursuant to such reorganization provisions the Trust is required,
by reason of the

                                       84
<PAGE>

Trust 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 Indenture Trustee and/or the Pass Through Trustee
actually receives any Excess Amount (as hereinafter defined) which reflects any
payment by the Trust on account of (b) above, then the Indenture Trustee and/or
the Pass Through Trustee, as the case may be, shall promptly refund to the Trust
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 Indenture Trustee or the Pass Through Trustee if the Trust had
not become subject to the recourse liability referred to in (b) above.

      Section 10.15 Ownership of and Rights in Units and Pledged Units. The sale
of the Units described on Schedule 1-A hereto and the Existing Equipment
Subleases, the Pledged Units and the Existing Pledged Equipment Leases by TRLTII
contemplated hereby is intended for all purposes to be a true sale of all of
TRLTII's right, title and interest in and to such Units, the Existing Equipment
Subleases, the Pledged Units and the Existing Pledged Equipment Leases to the
Lessee, which shall be the legal owner thereof upon such sale. Upon consummation
of the sale and leaseback transactions contemplated hereby, the Lessee's
interest in such 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 such Units. The rights of the Indenture Trustee in and to such 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 such Units except as a beneficiary of the Lien 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 No Petition. Each party hereto agrees that, prior to the
date which is one year and one day after payment in full of all outstanding
Equipment Notes and all obligations of the Lessee under the Operative Agreements

party hereto shall authorize the Lessee, the Owner Trust or the Marks Company to
commence a voluntary winding-up or other voluntary case or other proceeding

the Owner Trust or the Marks Company or their debts under any bankruptcy,
insolvency or other similar law now or hereafter in effect in any jurisdiction
or seeking the appointment of an administrator, a trustee, receiver, liquidator,
custodian or other similar official of the Lessee, the Owner Trust or the Marks
Company or any substantial part of its property or to consent to any such relief
or to the appointment of or taking possession by any such official in an
involuntary case or other proceeding commenced against the Lessee, the Owner
Trust or the Marks Company, or to make a general assignment for the benefit of
any party hereto or any other creditor of the Lessee, the Owner Trust or the
Marks Company, and (ii) none of the parties hereto shall commence or join with
any other Person in commencing any proceeding against the Lessee, the Owner
Trust or the Marks Company under any bankruptcy, reorganization, liquidation or
insolvency law or statute now or hereafter in effect in any jurisdiction. Each
of the parties hereto agrees that, prior to the date which is one year and one
day after the payment in full of all outstanding Equipment Notes and all
obligations of the Lessee under the Operative Agreements and release of all
Collateral held under the Collateral Agency Agreement, it will not institute
against, or join any other

                                       85

proceedings or similar proceeding under the laws of the United States or any
state of the United States.

nonexclusive general jurisdiction of the courts of the State of New York, the

proceeding may be effected by mailing a copy thereof by registered or certified

party hereto at its address set forth in Section 10.4 hereof, or at such other
address of which the other parties shall have been notified pursuant thereto;
and

                  (iv) agrees that nothing herein shall affect the right to
effect service of process in any other manner permitted by law or shall limit
the right to sue in any other jurisdiction.

      Section 10.18 WAIVER OF JURY TRIAL. EACH PARTY TO THIS AGREEMENT HEREBY
IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY
ACTION, SUIT OR COUNTERCLAIM ARISING IN CONNECTION WITH THIS AGREEMENT.

      Section 10.19 No Partnership Created. The parties hereto do not intend to
create, and nothing herein shall be construed as creating, a partnership or
joint venture for federal income tax purposes. Each party hereto agrees (i) that

hereto or any other person with respect to any Unit, Existing Equipment Sublease
or Permitted Sublease, (ii) not to hold itself out to the public as a partner
with any other party hereto, (iii) not to share any profits (including rent or

interest in any Unit, Existing Equipment Sublease or Permitted Sublease, and
(iv) that unless (x) otherwise required by the Internal Revenue Service or like
governmental authority with jurisdiction over income tax matters (the "Required
Position") or (y) such party receives an opinion of its independent tax counsel
that there is no "reasonable basis" (within the meaning of Treasury Regulation
Section 1.6662-3(b)(3)) to claim that no partnership exists, and such party
delivers notice of the receipt of such opinion or notice of the Required
Position to the other parties hereto within ten (10) Business Days of its
receipt of such opinion or notice of the Required Position, it will not file any

                                       86
<PAGE>

partnership or other joint income tax return with respect to items of income,
loss, deduction, or credit attributable to its interest in any Unit, Existing
Equipment Sublease or Permitted Sublease.

      Section 10.20 Amendments to Operative Agreements That Are Not Lessee
Agreements. The Owner Trustee, the Indenture Trustee and the Participants shall
not terminate the Operative Agreements to which the Lessee is not or will not be
a party, or amend, supplement, waive or modify in any manner such Operative
Agreements to which the Lessee is not or will not be a party, except (i) in
accordance with such Operative Agreements in effect on the date hereof (as
amended, modified or supplemented from time to time in accordance with the terms
hereof and of such Operative Agreements), or (ii) in a manner that is not
adverse to the Lessee or to any of its rights or interests under any of the
Operative Agreements, unless the prior written consent of the Lessee is
obtained. Without limiting the generality of the foregoing, each of the Owner
Participant and the Owner Trustee, the Pass Through Trustee and the Indenture
Trustee (as applicable) agrees that, in any event, it will not amend Section
2.10 or Article IX of the Indenture or Article IX of the Trust Agreement without
the prior written consent of the Lessee.

Each party to this Agreement acknowledges notice of any confidentiality

be bound by such confidentiality provisions as they relate to the identity of
any sub-sublessees or sublessees under such Subleases and Pledged Equipment
Leases, respectively.

SECTION 11. LIMITED GUARANTY.

      Section 11.1 Limited Guaranty. Trinity hereby irrevocably and
unconditionally guarantees for the benefit of each of the Owner Participant, the
Owner Trustee, Trust Company, the Indenture Trustee, the Pass Through Trustee
and the Policy Provider (each, together with their respective permitted
successors and assigns, a "Guaranty Party") the full and punctual payment of all
amounts payable by the Lessee under Sections 7.1 and 7.2 of this Agreement and
all amounts payable by TILC under Section 7.4 of this Agreement (all such
obligations being hereinafter referred to as the "Guaranteed Obligations"). Upon
failure by the Lessee to pay punctually or perform any Guaranteed Obligation,
Trinity shall forthwith on demand pay the amount not so paid or perform the
obligation not so performed in the manner specified in the Operative Agreements.
All payments by Trinity under this guaranty shall be made on the same basis as
payments by the Lessee under the Operative Agreements. This guaranty shall
constitute a guaranty of punctual payment and not of collection, and Trinity
specifically agrees that it shall not be necessary, and that Trinity shall not
be entitled to require, before or as a condition of enforcing the liability of
Trinity under this Section 11 or requiring payment or performance of the
Guaranteed Obligations by Trinity hereunder, or at any time thereafter, that any
Person: (a) file suit or proceed to obtain or assert a claim for personal
judgment against Lessee or any other Person that may be liable for any
Guaranteed Obligation; (b) make any other effort to obtain payment or
performance of any Guaranteed Obligation from Lessee or any other Person that
may be liable for such Guaranteed Obligation; (c) foreclose against or seek to
realize upon any security now or hereafter existing for such Guaranteed
Obligation; (d) exercise or assert any other right or remedy to which such
Person is or be entitled in connection with any Guaranteed Obligation or any
security or other guaranty therefor or (e) assert or file any claim against the
assets of Lessee or any other Person liable for any Guaranteed Obligation.

                                       87

      Section 11.2 Guaranty Unconditional. The obligations of Trinity hereunder

original and, without limiting the generality of the foregoing, shall not be
released, discharged or otherwise affected by any circumstance or condition,
including, without limitation, the occurrence of any one or more of the
following events:

            (a) any abatement, setoff, defense, reduction, recoupment,
counterclaim, extension, renewal, settlement, compromise, waiver or release in

operation of law or otherwise;

            (b) any modification or amendment of or supplement to the Operative
Agreements;

            (c) any change in the corporate existence, structure or ownership of
the Lessee, or any insolvency, bankruptcy, reorganization or other similar
proceeding affecting the Lessee or its assets or any resulting release or
discharge of any obligation of the Lessee contained in the Operative Agreements;

            (d) any other act or omission to act or delay of any kind by the
Lessee, the Owner Participant, the Owner Trustee, Trust Company, the Indenture
Trustee, the Pass Through Trustee, the Policy Provider or any Person or any
other circumstance whatsoever which might, but for the provisions of this
paragraph, constitute a legal or equitable discharge of or defense to Trinity's
obligations hereunder;

            (e) any invalidity, unenforceability, impossibility or illegality of
performance of any Operative Agreement or any document related thereto or any of
the Guaranteed Obligations under the Operative Agreements or any provision
thereof, the absence of any action to enforce the same or waiver or consent with
respect to any provision thereof;

            (f) any change in the time, manner or place of performance or
payment of, or in any other term of, all or any of the amounts payable under any
Operative Agreement or any other modification, supplement or amendment or waiver
of or any consent to any departure from the terms and conditions thereof;

            (g) any taking, exchange, release or non-perfection of any
collateral, any furnishing or acceptance of any additional security or any
exchange, surrender, substitution or release of any security or any taking,
release, amendment or waiver of, consent to, or departure from any other
guaranty for, all or any of the Guaranteed Obligations;

            (h) the waiver by any Guaranty Party or any other Person of the
performance or observance by Lessee of any Guaranteed Obligation or of any
default in the performance or observance thereof (except to the extent that the
payment or performance of any Guaranteed Obligation is waived in writing by the
relevant Guaranty Party) or any extension by any Guaranty Party of the time for
payment or performance and discharge by Lessee of any Guaranteed Obligation or
any extension or renewal of any Guaranteed Obligation;

            (j) any failure or delay in the enforcement of the obligations of
any Person under any Operative Agreement (or any other agreement) or any
provision thereof;

            (k) any setoff, counterclaim, deduction,, defense, abatement,
suspension, deferment, diminution, recoupment, limitation or termination
available with respect to any Guaranteed Obligation, and, to the extent
permitted by Law, irrespective of any other circumstances that might otherwise
limit recourse by or against Trinity or any other Person;

            (l) the obtaining, the amendment or the release of the primary or
secondary obligation of any other Person, in addition to Trinity, with respect
to any Guaranteed Obligation;

            (m) any compromise, alteration, amendment, modification, extension,
renewal, release or other change, or waiver, consent or other action, or delay
or omission or failure to act, in respect of any of the terms, covenants or
conditions of any Operative Agreement (except to the extent that the payment or
performance of any Guaranteed Obligation is waived in writing by the relevant
Guaranty Party), or any other agreement or any related document referred to
therein, or any assignment or transfer of any thereof;

            (n) to the maximum extent permitted by Law, any other circumstance
that might otherwise constitute a legal or equitable defense or discharge of a
guarantor or surety with respect to any Guaranteed Obligation (other than the
defense of payment or performance in full by Lessee or Trinity with respect to
any Guaranteed Obligation);

            (o) any matter of application of collateral, or proceeds thereof, to
all or any of the Guaranteed Obligations or any matter of sale or other
disposition of any collateral for all or any of the Guaranteed Obligations or

            (p) any regulatory change or other governmental action (whether or
not adverse); the partial payment or performance of the Guaranteed Obligations
(whether as a result of the exercise of any right, remedy, power or privilege or
otherwise) shall be accepted or received; or any default, failure or delay,
whether as a result of actual or alleged force majeure, commercial
impracticality or otherwise, in the performance of the Guaranteed Obligations,
or by any other act or circumstance (including, without limitation, any defect
in the title to the 2004-1A SUBI Certificate) which may or might in any manner
or to any. extent vary the risk of Trinity, or which would otherwise operate as
a discharge of Trinity as a matter of law.

Should any money due or owing under this guaranty not be recoverable from
Trinity due to any of the matters specified in Sections 11.2 (a) through (p)
above, then, in any such case, such money shall nevertheless be recoverable from
Trinity as though Trinity were principal debtor in respect thereof and not
merely a guarantor and shall be paid by Trinity forthwith.

                                       89
<PAGE>

      Section 11.3 Discharge Only Upon Payment and Performance in Full;
Reinstatement in Certain Circumstances. Trinity's obligations hereunder are
absolute and unconditional and shall remain in full force and effect until all
the Guaranteed Obligations have been irrevocably paid and performed in full. If
at any time any Guaranteed Obligation payable by the Lessee or any payment by
Trinity hereunder is rescinded or must be otherwise restored or returned upon
the insolvency, bankruptcy or reorganization of the Lessee or Trinity, or upon
or as a result of the appointment of a receiver, intervenor, or conservator of,
or trustee or similar officer for, the Lessee or Trinity or any substantial part
of its property, all as though such payment had not been made and any statute of
limitations in favor of Trinity against any Guaranty Party relating to any such
amount to be restored or returned shall be tolled, or deemed to have been
tolled, to the extent permitted by law, during the period from the date such
payment was made to such Guaranty Party until the date such Guaranty Party so
restores or returns such amount or otherwise, Trinity's obligations hereunder
with respect to such payment shall be reinstated at such time as though such
payment had been due but not made at such time.

            The obligations under this Section 11 are continuing and all
liabilities to which they apply or may apply under the terms hereof shall be
conclusively presumed to have been created in reliance hereon. No failure or
delay on the part of any Guaranty Party in exercising any right, power or
privilege hereunder shall operate as a waiver thereof; nor shall any single or
partial exercise of any right, power or privilege hereunder preclude any other
or further exercise thereof or the exercise of any other right, power of
privilege. The rights, powers and remedies herein expressly provided are
cumulative and not exclusive of any rights, powers and remedies which any
Guaranty Party would otherwise have. No notice or demand on Trinity in any case
shall entitle Trinity to any other further notice or demand in similar or other
circumstances or constitute a waiver of the rights of any Guaranty Party to any
other or further action in any circumstances without notice or demand.

      Section 11.4 Waiver by Trinity. Trinity irrevocably waives acceptance
hereof, presentment, demand, protest and any notice not provided for herein, as
well as any requirement that at any time any action be taken by any Person
against the Lessee or any other Person.

      Section 11.5 Subrogation. The obligations under this Section 11 are the
primary obligations of Trinity. Until the Guaranteed Obligations hereunder have
been indefeasibly paid and performed in full, Trinity irrevocably waives any and
all rights to which it may be entitled, by operation of law or otherwise, upon
making any payment hereunder to be subrogated to the rights of the payee against
the Lessee with respect to such payment or otherwise to be reimbursed,
indemnified or exonerated by or for the account of the Lessee, in respect
thereof.

      Section 11.6 Payments. All payments to be made by Trinity under this
Section 11 to a Guaranty Party shall be paid as provided for in the relevant
Operative Agreement or, if applicable, to such Guaranty Party at the address and
to the account specified in the notice demanding payment be made by Trinity by
wire transfer on the date due at or before 11:00 a.m. (Chicago time) in
immediately available funds to the party to which such payment is to be made, if
such party has provided Trinity with instructions for such wire transfer.

      Section 11.7 Withholding Taxes. All payments by Trinity hereunder shall be
made free and clear of, and without deduction or withholding for or on account
of, any Taxes, unless such

                                       90
<PAGE>

deduction or withholding is required by Law. If Trinity shall be required by Law
to make any such deduction or withholding, then Trinity shall make such
deduction or withholding and pay such additional amounts as may be necessary in
order that the net amount received by the applicable Guaranty Party, after
reduction by such deduction or withholding (including any such Taxes as a result
of additional Taxes payable with respect to the receipt or accrual of amounts
payable pursuant to this sentence), shall be equal to the full amount that such
Guaranty Party would have received, after deduction or withholding of Taxes, had
Lessee discharged its obligations (including its tax gross-up obligations).

            Any amounts deducted or withheld by Trinity for or on account of
Taxes shall be paid over to the government or taxing authority imposing such
Taxes in accordance with applicable Law, and Trinity shall provide the
applicable Guaranty Party as soon as practicable with such tax receipts or other
official documentation with respect to the payment of such Taxes as may be
available. Each Guaranty Party shall honor all reasonable requests from Trinity
to file, or to provide Trinity with, such forms, statements, certificates or
other documentation as shall enable such Guaranty Party or Trinity to claim a
reduced rate of tax or exemption from tax with respect to any Taxes required to
be borne by Trinity pursuant to this Section 11.7; provided that such Guaranty
Party is legally entitled to complete, execute and file or provide such
documentation and in such Guaranty Party's judgment such completion, execution
or filing or provision would not have a material adverse effect on such Guaranty
Party.
