                            EQUIPMENT LEASE AGREEMENT
                                 (TRLI 2001-1A)

         This Equipment Lease Agreement (TRLI 2001-1A), dated as of May 17, 2001
(this "Lease"), is by and between TRLI 2001-1A Railcar Statutory Trust by State
Street Bank and Trust Company of Connecticut, National Association, not in its
individual capacity except as expressly provided herein, but solely as trustee
under the Trust Agreement, as Lessor, and Trinity Rail Leasing I L.P., a Texas
limited partnership, as Lessee.

         In consideration of the mutual agreements herein contained and other
good and valuable consideration, receipt of which is hereby acknowledged, the
parties hereto agree as follows:

SECTION 1. Definitions.

         Unless otherwise defined herein or required by the context, all
capitalized terms used herein shall have the respective meanings assigned to
such terms in Appendix A hereto for all purposes of this Lease.

SECTION 2. Acceptance and Leasing of Equipment.

         Subject to Section 4 of the Participation Agreement, Lessor hereby
agrees to accept delivery of each Unit from Lessee and to lease such Unit to
Lessee hereunder, and Lessee hereby agrees, immediately following such
acceptance by Lessor, to lease from Lessor hereunder such Unit, such acceptance
by Lessor and lease by Lessee to be evidenced by the execution and delivery by
Lessee and Lessor of a Lease Supplement covering such Unit, all in accordance
with Section 2.3(b) of the Participation Agreement. Lessee hereby agrees that
its execution and delivery of a Lease Supplement covering any Unit shall,
without further act, irrevocably constitute acceptance by Lessee of such Unit
for all purposes of this Lease.

SECTION 3. Term and Rent.

         Section 3.1 Lease Term. The basic term of this Lease (the "Basic Term")
shall commence on the Basic Term Commencement Date and, subject to earlier
termination pursuant to Section 10, 11, 15 or 22.1, shall expire at 11:59 p.m.
(Chicago, Illinois time) on the Basic Term Expiration Date. Subject and pursuant
to Section 22.4, Lessee may elect one or more Renewal Terms and, as provided in
Section 22.7 hereof, in certain circumstances a Renewal Term shall be deemed to
have occurred with respect to some or all of the Units.


                                       1

         Section 3.2 Basic Rent. Lessee hereby agrees to pay Lessor Basic Rent
for each Unit throughout the Basic Term applicable thereto in consecutive
monthly installments payable on each Rent Payment Date. Each such monthly
payment of Basic Rent shall be in an amount equal to the product of the
Equipment Cost for such Unit multiplied by the Basic Rent percentage set forth
opposite such Rent Payment Date on Schedule 3-A to the Participation Agreement
(as such Schedule 3-A shall be adjusted pursuant to Section 2.6 of the
Participation Agreement). Schedule 3-B to the Participation Agreement sets forth
the Basic Rent allocated for Federal income tax purposes to each lease period
and calendar year throughout the Basic Term and in addition, sets forth that for
certain months, amounts of Basic Rent shall be allocated to the following and/or
preceding calendar year. Schedule 3-B to the Participation Agreement also sets
forth the application of Basic Rent payments to the calendar year to which such
payments relate. It is the intention of Lessor and Lessee that the allocations
of Basic Rent set forth on Schedule 3-B to the Participation Agreement
constitute specific allocations of fixed rent within the meaning of Treas. Reg.
Section 1.467-1(c)(2)(ii). Stipulated Loss Amounts and Termination Amounts have
been calculated on the basis that (i) any Basic Rents actually due on the date
of such calculation shall not be paid and (ii) any Basic Rents scheduled to have
been paid prior to the date of such calculation are assumed to have been paid
and have been appropriately reflected in such calculations. Lessor and Lessee
agree to include in income and deduct the Basic Rents allocated to each lease
period and calendar year according to Schedule 3-B of the Participation
Agreement. In addition, Lessor and Lessee intend that under no circumstances are
any Basic Rents to be considered related to (i) any period after the calendar
year succeeding the calendar year in which such Basic Rents are payable or any
period before the calendar year preceding the calendar year in which such Basic
Rents are payable or (ii) the period beginning on the Closing Date and ending on
(but not including) August 17, 2001 (the "Basic Rent Holiday").

         Notwithstanding anything to the contrary contained herein or in the
Participation Agreement, each installment of Basic Rent (both before and after
any adjustment pursuant to Section 2.6 of the Participation Agreement) shall be,
under any circumstances and in any event, in an amount at least sufficient for
Lessor to pay in full as of the due date of such installment, any payment of
principal of and interest on the Equipment Notes required to be paid by Lessor
pursuant to the Indenture on such due date in accordance with the Scheduled
Amortization.

         Section 3.3 Supplemental Rent. Lessee also agrees to pay to Lessor, or
to whosoever shall be entitled thereto, any and all Supplemental Rent, promptly
as the same shall become due and owing, or where no due date is specified,
promptly after demand by the Person entitled thereto, and in the event of any
failure on the part of Lessee to pay any Supplemental Rent, Lessor shall have
all rights, powers and remedies provided for herein or by law or equity or
otherwise as in the case of



                                       2
<PAGE>   9



nonpayment of Basic Rent. Lessee will also pay, as Supplemental Rent, (i) on
demand, to the extent permitted by applicable law, an amount equal to Late
Payment Interest on any part of any installment of Basic Rent not paid when due
for any period for which the same shall be overdue and on any payment of
Supplemental Rent not paid when due or promptly after demanded for the period
from such due date or demand date, as applicable, until the same shall be paid
and (ii) as and when due in accordance with the Trust Indenture or the
Participation Agreement, any Make-Whole Amount payable with respect to any
Equipment Note, including, without limitation, amounts of Make-Whole Amount due
in the case of the termination of this Lease with respect to any Unit pursuant
to Section 10, in the case of the purchase of any Unit (but not in the case of a
purchase of the Beneficial Interest or if the Equipment Notes are assumed in
accordance with the Operative Agreements) pursuant to Section 22.1 or Section
6.9 of the Participation Agreement, and in the case of any refinancing of the
Equipment Notes pursuant to Section 10.2 of the Participation Agreement. All
Supplemental Rent to be paid pursuant to this Section 3.3 shall be payable in
the type of funds and in the manner set forth in Section 3.5.

         Section 3.4 Adjustment of Rent. Lessee and Lessor agree that the Basic
Rent, Stipulated Loss Values, Stipulated Loss Amounts, Termination Values and
Termination Amount percentages and the Early Purchase Price shall be adjusted to
the extent provided in Section 2.6 of the Participation Agreement.

         Section 3.5 Manner of Payments. All Rent (other than Supplemental Rent
payable to Persons other than Lessor, which shall be payable to such other
Persons in accordance with written instructions furnished to Lessee by such
Persons, as otherwise provided in any of the Operative Agreements or as required
by law) shall be paid by Lessee to Lessor at its office at 225 Asylum Street,
Goodwin Square, Hartford, CT, 06103, Attention: Corporate Trust Administration,
provided, that so long as the Indenture shall not have been discharged pursuant
to the terms thereof, Lessor hereby directs, and Lessee hereby agrees, that all
Rent (excluding Excepted Property) payable to Lessor shall be paid from the
Payment Account directly to the Indenture Trustee at the times and in funds of
the type specified in this Section 3.5 at the office of the Indenture Trustee at
135 S. LaSalle Street, Suite 1960, Chicago, IL 60603, ABA No. 071000505, Account
608775318, Attn: Kristine Schossow, Corporate Trust Services Division, Trust
TRLI 2001-1A, or at such other location in the United States of America as the
Indenture Trustee may otherwise direct. All Rent shall be paid by Lessee to the
recipient not later than 11:00 a.m. Chicago, Illinois time on the date of such
payment in funds consisting of lawful currency of the United States of America,
which shall be immediately available. Notwithstanding anything contained in this
Lease to the contrary, any amounts received pursuant to distribution from any of
the Accounts (as such term is defined in the Collateral Agency Agreement) shall
for all purposes hereof be deemed payment in satisfaction of the related
obligation hereunder to which such distribution relates and any failure by
Lessor, the Indenture Trustee or any Indemnified Party to receive from the



                                       3
<PAGE>   10



Collateral Agent the full amount of any such distribution measured by reference
to Basic Rent, Supplemental Rent or any component thereof shall be deemed a
failure by Lessee to pay such Basic Rent or Supplemental Rent hereunder, as the
case may be.

SECTION 4. Ownership and Marking of Equipment.

         Section 4.1 Retention of Title. Lessor shall and hereby does retain
full legal title to and beneficial ownership of each Unit notwithstanding the
delivery to and possession and use of such Unit by Lessee hereunder or any
Sublessee under any sublease permitted hereby.

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

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

with appropriate changes thereof and additions thereto as from time to time may
be required by law in order to protect Lessor's right, title and interest in and
to such Unit, its rights under this Lease and the rights of the Indenture
Trustee. Except as provided hereinabove, Lessee will not place any such Units in
operation or exercise any control or dominion over the same until the required
legend shall have been so marked on both sides thereof, and will replace
promptly any such word or words in such legend which may be removed, defaced,
obliterated or destroyed. In the event of a change in the reporting mark of any
Unit, within 60 days after a Responsible Officer of the Manager has received
notice of any such changed mark, a statement of the new reporting mark to be
substituted therefor shall be delivered by Lessee to Lessor and, so long as the
Indenture shall not have been discharged pursuant to its terms, to the Indenture
Trustee. As soon as practicable after the delivery of such statement a
supplement to this Lease and, if not so discharged, the Indenture, with respect
to such new reporting marks, shall be filed or recorded in all public offices
where this Lease and the Indenture shall have been filed or recorded and in such
other places, if any, where Lessor and, so long as the Indenture shall not have
been



                                       4
<PAGE>   11



discharged pursuant to its terms, the Indenture Trustee may reasonably request
in order to protect, preserve and maintain its right, title and interest in the
Units. The costs and expenses of all such supplements, filings and recordings
shall be borne by Lessee.

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

SECTION 5. Disclaimer of Warranties.

         Section 5.1 Disclaimer of Warranties. Without waiving any claim Lessee
may have against any seller, supplier or manufacturer, LESSEE ACKNOWLEDGES AND
AGREES THAT (i) EACH UNIT IS OF A SIZE, DESIGN, CAPACITY AND MANUFACTURE
SELECTED BY AND ACCEPTABLE TO LESSEE, (ii) LESSEE IS SATISFIED THAT EACH UNIT IS
SUITABLE FOR ITS PURPOSES AND LESSEE HAS ACCEPTED EACH UNIT, (iii) NEITHER
LESSOR NOR OWNER PARTICIPANT IS A MANUFACTURER OR A DEALER IN PROPERTY OF SUCH
KIND OR HAS INSPECTED THE UNITS PRIOR TO DELIVERY TO AND ACCEPTANCE BY LESSEE,

AND OWNER PARTICIPANT EXPRESSLY DISCLAIMS SELECTION OF THE UNITS, except that
Lessor, in its individual capacity, represents and warrants that on the Closing
Date, Lessor shall have received whatever title to each Unit as was conveyed to
Lessor by Lessee and each Unit will be free of Lessor's Liens attributable to
Lessor and provided that the foregoing disclaimer in clause (v) shall not extend
to Owner Participant's representation and warranty contained in Section 3.5(e)
of the Participation Agreement. Lessor hereby appoints and constitutes Lessee
its agent and attorney-in-fact during the Lease Term to assert and enforce, from
time to time, in the name and for the account of Lessor and Lessee, as their
interests may appear, but in all cases at the sole cost and expense of Lessee,
whatever claims and rights Lessor may have as owner of each Unit against the
manufacturers or any prior owner thereof; provided, however, that if at any time
a Lease Event of Default shall have occurred and be continuing, at Lessor's
option, such power of attorney shall terminate, and Lessor may assert and
enforce, at Lessee's sole cost and expense, such claims and rights. Lessee's
delivery of a Lease Supplement shall be conclusive evidence as between Lessee
and Lessor that all Units described therein are in all the foregoing respects
satisfactory to Lessee, and Lessee will not assert any claim of any nature
whatsoever against Lessor based on any of the foregoing matters.

         Section 5.2 Rights Under Existing Equipment Subleases. Unless a Lease
Event of Default shall have occurred and be continuing under Section 14 and
Lessor shall have given written notice to Lessee, Lessor agrees to make
available to Lessee such rights as Lessor may have, and Lessee shall be entitled
to exercise all rights of Lessor under, each Sublease.

SECTION 6. Return of Equipment; Storage.

         Section 6.1 Return; Holdover Rent. (a) Not less than 180 days prior to
the end of the Basic Term or the end of any Renewal Term, if Lessee has elected
to return the Units under Section 22.2, Lessee will provide Lessor with a list
of not less than ten (10) alternative storage locations ("Storage Locations")
used for the storage of rolling stock within the Contiguous United States
sufficient to store the Units and the available storage capacities of such
locations. Unless Lessee shall have purchased the Units pursuant to Section 22
of this Lease or pursuant to Section 6.9 of the Participation Agreement, not
less than 90 days prior to the end of the Lease Term, Lessor will give Lessee
irrevocable notice of its decision either to take possession of or store the
Units. If Lessor shall have decided to take possession of the Units, the terms
of Section 6.1(b) will apply. If Lessor shall have decided to store the Units,
the terms of Section 6.1(c) will apply.

         (b) Unless Lessee shall have purchased the Units pursuant to Section 22
of this Lease or pursuant to Section 6.9 of the Participation Agreement, if
Lessor shall have decided to take possession of the Units, Lessee will, at its
sole risk and expense, deliver possession of the Units at any storage location,
f.o.b. such



                                       6
<PAGE>   13



location, (i) as may be agreed upon by Lessor and Lessee in writing or (ii) in
the absence of such agreement as Lessor may reasonably select by written notice
to Lessee on or before the 90th day before the end of the Lease Term; provided,
that (x) with respect to all Units being so delivered, there shall be no more
than ten (10) locations (each of which shall be located within the Contiguous
United States and shall have adequate storage capacities) and (y) Lessor's
notice shall specify the total number and type of Units to be delivered to each
location.

         (c) (i) Unless Lessee shall have purchased the Units pursuant to
Section 22 of this Lease or pursuant to Section 6.9 of the Participation
Agreement, if Lessor shall have elected to store the Units upon the expiration
of the Lease Term with respect thereto, Lessee shall store the Units free of
charge and at the risk and expense of Lessee for a period (the "Storage Period")
beginning, for any particular Storage Location, on the expiration of the Lease
Term for such Units (the "Storage Period Commencement Date") and ending not more
than 60 days thereafter. On or before the 90th day before the end of the Lease
Term, Lessor shall provide Lessee with written notice designating its choices
from among the Storage Locations provided by Lessee pursuant to Section 6.1(a).
Any storage provided by Lessee during the Storage Period shall be at the sole
risk and expense of Lessee, and Lessee shall maintain the insurance required by
Section 12.1 with respect to all stored Units. During the Storage Period, Lessee
will permit Lessor or any Persons designated by it, including the authorized
representative or representatives of any prospective purchaser or user of such
Units, to restencil the marks on such Units and to inspect the same during
Lessee's normal business hours upon at least three Business Days' prior written
or telephonic notice; provided, however, that such inspection and restenciling
shall not interfere with the normal conduct of Lessee's business; and provided,
further, that (x) such inspection and restenciling shall be at such Person's own
risk and expense, (y) Lessee shall be indemnified by Lessor against any loss or
damage incurred by it in connection with any such inspection or restenciling by
such Person and (z) Lessee (except in the case of Lessee's gross negligence or
willful misconduct) shall not be liable for any injury to, or the death of, any
person exercising, either on behalf of Lessor or any prospective purchaser or
user, the rights of inspection and restenciling granted pursuant hereto. Lessee
shall not be required to store any Unit after the Storage Period. If Lessee does
store any Unit after the expiration of the Storage Period, such storage shall be
at the sole risk and expense of Lessor.

         (ii) Upon the request and direction of Lessor (and at Lessor's sole
risk and expense), on not more than one occasion with respect to each stored
Unit and upon not less than 15 days' prior written notice from Lessor to Lessee,
Lessee will, on or before the expiration of the Storage Period, transport such
Unit to any railroad interchange point or points within the Contiguous United
States on any railroad lines or to any connecting carrier for shipment (with
appropriate instructions to cause such Unit to be transported to such locations
in the Contiguous United States as Lessor shall direct), whereupon Lessee shall
have no further liability or obligation with respect to such Unit.



                                       7
<PAGE>   14



         (iii) Upon receipt of Lessor's written notice designating its choices
from among the alternative Storage Locations provided by Lessee under Section
6.1(a), Lessee shall have the option to store such Units at such Storage
Locations as it shall choose in which case the Storage Period shall be at the
sole risk and expense of Lessee for a period of 60 days, during which period
Lessee shall be obligated to insure such Units as provided in Section 12. Upon
receipt of such notice, Lessee will promptly give notice to Lessor of the
locations at which Lessee will store such Units. If Lessee shall exercise such
option, Lessee shall on or before the expiration of the Storage Period transport
the Units to any railroad interchange point or points within the Contiguous
United States on any railroad lines or to any connecting carrier for shipment
(with appropriate instructions to cause such Units to be transported to such
locations (provided that such Units shall be transported to no more than ten
(10) locations, each having adequate storage capacity) designated by Lessor upon
not less than 15 days' prior written notice). The movement of any Unit from such
Unit's location as designated by Lessee pursuant to this Section 6.1(c)(iii) to
an interchange point thereafter designated by Lessor in accordance with the
foregoing sentence will be at the risk and expense of Lessor; provided, however,
that any incremental costs associated with movement from the storage facility
designated by Lessee pursuant to this clause (iii) over the costs that would be
incurred in movement from the storage facility designated by Lessor pursuant to
Section 6.1 (a) shall be for the account of Lessee. During any Storage Period,
Lessee shall store the Units in such manner as the Manager normally stores
similar units of railroad equipment owned or managed by it.

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

         (e) In the event any Unit is not (i) returned to Lessor in accordance
with the provisions of Section 6.1(b) on the last day of the Lease Term with
respect thereto, or, if requested by Lessor pursuant to Section 6.1(c),
delivered and stored on such last day of the Lease Term, and, in either case, in
the condition specified in Section 6.2 or (ii) deemed automatically renewed in
accordance with the provisions of Section 22.7, the Lease with respect to such
Unit shall continue in effect and Lessee shall pay to Lessor for each such day
from the scheduled expiration of the Lease Term with respect to such Unit until
the date on which such Unit is returned to Lessor in accordance with the
provisions of Section 6.1(b) and in the condition specified in Section 6.2, an
amount equal to the daily equivalent of the average Basic Rent for the Basic
Term or the Renewal Term, as applicable, to such



                                       8
<PAGE>   15



Unit. Notwithstanding the foregoing, nothing in this Section 6.1(e) shall be
construed as permitting or authorizing Lessee to fail to meet, or be construed
as Lessor consenting to or waiving any failure by Lessee to perform, Lessee's
obligation to return the Units in accordance with the requirements of this
Lease. Nothing herein shall be in abrogation of Lessor's right to terminate this
Lease under Section 15 as a result of such failure or to have such Unit returned
to it for possession or storage.

         Section 6.2 Condition of Equipment. Each Unit when returned to Lessor
pursuant to Section 6.1 shall be (i) capable of performing the functions for
which it was designed, with all loading and unloading components operating in
good working order with allowance for normal wear and tear, (ii) suitable for
continued commercial use in the commodity last carried immediately prior to such
return, (iii) suitable for use in interchange in accordance with then applicable
Federal regulations, the Field Manual of the AAR, the Interchange Rules and FRA
rules and regulations, (iv) in all material respects in the condition required
by Section 8.1, (v) in conformance with any requirement pertaining to warranties
of the manufacturer of the Units during the warranty period, (vi) empty, (vii)
unless industry custom or practice indicates to the contrary, steam cleaned or
otherwise cleaned in a comparable commercially acceptable manner and (viii) free
and clear of all Liens except Lessor's Liens. All logs, records, books and other
materials, or appropriate copies of any thereof, relating to the maintenance of
such Unit shall, upon Lessor's request, be delivered to Lessor or its designee
upon the return of such Unit. Lessor shall have the right to inspect any Unit
that is returned pursuant to Section 6.1 to ensure that such Unit is in
compliance with the conditions set forth in this Section 6.2, at Lessor's sole
cost, expense and risk (including, without limitation, the risk of personal
injury or death), by its authorized representatives, during Lessee's normal
business hours and upon reasonable prior notice to Lessee; provided, however,
that Lessee shall not be liable for any injury to, or the death of, any Person
exercising, on behalf of Lessor, the rights of inspection granted under this
Section 6.2 unless caused by Lessee's gross negligence or willful misconduct;
and further provided, that if such Unit is not in compliance with the conditions
set forth in this Section 6.2, then Lessee will (i) promptly take such steps as
are necessary to bring such Unit in compliance with the conditions set forth in
this Section 6.2 and (ii) pay the reason-able cost and expense of the original
inspection of such Unit and any reinspection of such Unit conducted by Lessor
required because of such non-compliance with Section 6.2. No inspection pursuant
to this Section 6.2 shall interfere with the normal conduct of Lessee's business
or the normal conduct of any Sublessee's business, and Lessee shall not be
required to undertake or incur any additional liabilities in connection
therewith. A Unit shall not be deemed to have been returned to Lessor for
purposes of this Lease unless and until it is in compliance with the conditions
set forth in this Section 6.2.

<PAGE>   16

SECTION 7. Liens.

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



SECTION 8. Maintenance; Possession; Compliance with Laws.

         Section 8.1 Maintenance and Operation. (a) Lessee, at its own cost and
expense, shall maintain, repair and keep each Unit, or cause the Manager under
the Management Agreement to maintain, repair and keep each Unit, (i) according
to prudent industry practice and in all material respects, in good working
order, and in good physical condition for railcars of a similar age and usage,
normal wear and tear excepted, (ii) in a manner in all material respects
consistent with maintenance practices used by the Manager or, with respect to
any Equipment subject to an Existing Equipment Sublease that is a Net Sublease,
the applicable Sublessee, as applicable, in respect of railcars owned or managed
by the Manager or, with respect to any Equipment subject to an Existing
Equipment Sublease that is a Net Sublease, the applicable Sublessee, as
applicable, similar in type to such Unit, (iii) in accordance in all material
respects with all manufacturer's warranties in effect and in accordance with all
applicable provisions, if any, of insurance policies required to be maintained
pursuant to Section 12 and (iv) in compliance in all material respects with any
applicable laws and regulations from time to time in effect, including, without
limitation, the Field Manual of the AAR, FRA rules and regulations and
Interchange Rules as they apply to the maintenance and operation of the Units in
interchange regardless of upon whom such applicable laws and regulations are
nominally imposed; provided, however, that, so long as the Manager or, with
respect to any Equipment subject to an Existing Equipment Sublease, the
applicable Sublessee, as applicable, is similarly contesting such law or
regulation with respect to all other similar equipment owned or operated by
Manager or, with respect to any Equipment subject to an Existing Equipment
Sublease, the applicable Sublessee, as applicable, Lessee may, in good faith and
by appropriate proceedings diligently conducted, contest the validity or
application of any such standard, rule or regulation in any reasonable manner
which does not materially interfere with the use, possession, operation or
return of any of the Units or materially adversely affect the rights or
interests of Lessor and the Indenture Trustee in the Units or hereunder or
other-wise expose Lessor, the Indenture Trustee or any Participant to criminal
sanctions or release Lessee from the obligation to return the Units in
compliance with the provisions of Section 6.2; provided further, that Lessee
shall promptly notify Lessor and Indenture Trustee in reasonable detail of any
such contest. In no event shall



                                       10
<PAGE>   17



Lessee discriminate in any material respect as to the use or maintenance of any
Unit (including the periodicity of maintenance or recordkeeping in respect of
such Unit) as compared to equipment of a similar nature which the Manager owns
or manages. Lessee will maintain in all material respects all records, logs and
other materials required by relevant industry standards or any governmental
authority having jurisdiction over the Units required to be maintained in
respect of any Unit, all as if Lessee were the owner of such Units, regardless
of whether any such requirements, by their terms, are nominally imposed on
Lessee, Lessor or Owner Participant.



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

         Section 8.2 Possession and Use. Lessee shall be entitled to the
possession of the Units and to the use of the Units by it or any Affiliate in
the United States and, subject to the remaining provisions of this Section 8.2
and Section 8.3, Canada and Mexico, only in the manner for which it was designed
and intended and so as to subject it only to ordinary wear and tear. In no event
shall Lessee use, store or permit the use or storage of any Unit in any
jurisdiction not included in the insurance coverage required by Section 12. The
Units shall be used primarily on domestic routes in the United States, and in no
event shall more than forty percent (40%) of the Units and the Other Units (as
determined by mileage records and measured annually on a calendar year basis) be
used outside the Contiguous United States at the same time. Nothing in this
Section 8.2 shall be deemed to constitute permission by Lessor to any Person
that acquires possession of any Unit to take any action inconsistent with the
terms and provisions of this Lease or any of the other Operative Agreements.

         Section 8.3 Sublease. Lessee shall be entitled, without the prior
approval of Lessor, to enter into a sublease, car contract or other contract
granting permission for the use of a Unit to:



                                       11
<PAGE>   18



         (i) a railroad company or companies (that is not a Credit Bankrupt,
Trinity or any Affiliate of Trinity) organized under the laws of the United
States of America or any state thereof or the District of Columbia, Canada or
any province thereof, or Mexico or any state thereof, upon lines of railroad
owned or operated by such railroad company or companies or over which such
railroad company or companies have trackage rights or rights for operation of
their trains, and upon connecting and other carriers in the usual interchange of
traffic;

         (ii) responsible companies (i.e., a company with which the Manager
would do business in the ordinary course of its business with respect to
railcars which it owns or manages) (other than railroad companies, Trinity,
Affiliates of Trinity or Credit Bankrupts) for use in their business; or

         (iii) wholly-owned Subsidiaries of Trinity organized under the laws of
(x) Canada or any political subdivision thereof (each a "Canadian Affiliate") or
(y) Mexico or any political subdivision thereof (each a "Mexican Affiliate")
(subleases to any of such sublessees referred to in clauses (i), (ii) or (iii)
of this Section 8.3 being herein referred to as "Permitted Subleases");

provided, however, that Lessee shall not (A) sublease to a sublessee organized
under the laws of Mexico or any state thereof (a "Mexican Sublessee") if, after
giving effect to such sublease, the percentage of Units, Other Units and Pledged
Units in the aggregate (as measured by number of Units, Other Units and Pledged
Units and not mileage records) subleased to Mexican Sublessees exceeds the
lesser of (I) 7% (or, with Rating Agency Confirmation, 20%) of the Units, Other
Units and the Pledged Units in the aggregate, or (II) the percentage of railcars
leased or subleased to Mexican Sublessees in the Total Managed Fleet, and (B)
sublease more than 50 Units and Other Units to any single Mexican Sublessee
(other than (x) with Rating Agency Confirmation, to a Mexican Affiliate or (y) a
Mexican Sublessee (I) with a credit rating of at least BBB and Baa2 as
determined by S&P and Moody's, respectively (or, in the event that either S&P or
Moody's shall not or cease to provide a credit rating for such entity, a credit
rating of at least BBB or Baa2 by S&P or Moody's, as the case may be) or (II)
with a full, unconditional irrevocable guaranty from such Mexican Sublessee's
parent with a credit rating at least BBB and Baa2 as determined by S&P and
Moody's, respectively, or (III) with a letter of credit from a provider with a
credit rating at least A+ or A1 as determined by S&P and Moody's, respectively),
provided, further, that Lessee shall not at any time sublease more than 20% (or,
with Rating Agency Confirmation, 30%) of the Units and the Other Units (as
measured by number of Units and Other Units and not mileage records) in the
aggregate to Canadian Affiliates, provided, further, that any Unit subleased to
a Canadian Affiliate or a Mexican Affiliate shall be sub-subleased to Persons of
type described in clause (i) or (ii) above pursuant to a sub-sublease containing
terms and conditions similar in all material respects to the applicable sublease
between Lessee and the applicable Canadian Affiliate or Mexican Affiliate and,
provided, further, that no sub-sublease may provide greater rights to the
sub-sublessee than those provided to the sublessee in the related sublease.



                                       12
<PAGE>   19



         Each Sublease (and to the extent permitted, sub-sublease) other than
Existing Equipment Subleases shall include appropriate provisions so that such
sublease (i) shall require the payment of rent (x) in dollars (y) at Fair Market
Rental Value and (z) not disproportionately in the earlier term of the sublease
compared to in the later term of the sublease; (ii) shall not permit any
sub-subleasing (or in the case of any sub-sublease, any subleasing), other than
(A) sub-subleases by Canadian Affiliates or Mexican Affiliates to Persons of the
type described in clauses (i) or (ii) of the immediately preceding paragraph
containing terms and conditions similar in all material respects to the
applicable sublease between Lessee and the applicable Canadian Affiliate or
Mexican Affiliate, (B) "single trip" subleases or (C) sub-subleases by Permitted
Sublessees so long as such sub-sublease is (X) of a term of not more than one
year, (Y) subject and subordinate to the Sublease and (Z) to a sub-sublessee and
on terms such that it would be a Permitted Sublease if it were entered into
directly by the Partnership and shall not permit any sub-sub-sub leasing, (iii)
provide that the rights of the Sublessee to offset or otherwise set-off against
amounts due to Lessee from any such Sublessee under the applicable Sublease be
limited to matters arising under the Sublease (except that the Sublessee may
offset or otherwise set off amounts due to the Marks Company Trustee under the
Sublease), (iv) without regard to the payment of Basic Rent or the Lease Term,
shall not include any term or provision which is inconsistent with the terms and
conditions of this Lease or which could reasonably be expected to result in
material adverse consequences to Lessor, any Participant or the Indenture
Trustee (it being agreed that a sublease substantially in the form attached as
Exhibit B-1 or Exhibit B-2 satisfies the provisions of this sentence) and (v)
does not have a term which extends three years beyond the later of (i) the Basic
Term Expiration Date or (ii) if applicable, the end of any Renewal Term then in
effect.

         Lessee will use commercially reasonable efforts to have each Sub-lease
other than Existing Equipment Subleases (i) provide that such Sublease and all
rights of the Sublessee (and of any other person claiming or who may hereafter
claim under or through the Sublessee) under such Sublease, including any
purchase options of the Sublessee thereunder, be made subject and subordinate to
the terms of this Lease and (ii) be substantially in the form attached as
Exhibit B-1 or Exhibit B-2.

         Notwithstanding the foregoing, in no event shall Lessee or any of its
Affiliates be required to take any action to perfect any security interest which
any Person may have in any Sublease, other than the filing of a UCC-1 Financing
Statement against the Partnership in the jurisdiction in which the Partnership's
chief executive office is located and in the Partnership's jurisdiction of
formation covering all Subleases generally.

         No sublease entered into by Lessee hereunder shall relieve Lessee of



                                       13
<PAGE>   20



any liability or obligation hereunder, which shall be and remain those of a
principal and not a surety. Nothing in this Section 8.3 shall be deemed to
constitute permission to any Person in possession of any Unit pursuant to any
such sublease to take any action inconsistent with the terms and provisions of
this Lease or any of the other Operative Agreements. As used in this Section
8.3, "sublease" as a noun means a sublease, car contract or other contract
granting permission for the use of a Unit and "sublease" as a verb means to
enter into any of the foregoing.

SECTION 9. Modifications.

         Section 9.1 Required Modifications. In the event a Required
Modification to a Unit is required, Lessee agrees to make such Required
Modification at its own expense; provided, however, that Lessee may, in good
faith and by appropriate proceedings diligently conducted, contest the validity
or application of any such law, regulation, requirement or rule in any
reasonable manner which does not materially interfere with the use, possession,
operation or return of any Unit or materially adversely affect the rights or
interests of Lessor or the Indenture Trustee in the Units or hereunder or
otherwise expose Lessor, the Indenture Trustee or any Participant to criminal
sanctions or relieve Lessee of the obligation to return the Units in compliance
with the provisions of Section 6.2; provided, further, that, with respect to a
Unit subject to a Full Service Sublease, the Manager, and with respect to a Unit
subject to a Net Sublease, the Sublessee, as applicable, is similarly contesting
such law, regulation, requirement or rule with respect to all other similar
equipment owned or operated by the Manager or the Sublessee, as applicable.
Title to any Required Modification shall immediately vest in Lessor.
Notwithstanding anything herein to the contrary, if Lessee, on a
non-discriminatory basis, determines in its reasonable judgment (as evidenced by
an Officer's Certificate of Lessee to such effect, confirmed by an Officer's
Certificate of the Manager) that any Required Modification to a Unit would be
economically impractical and the Manager certifies that it has made a similar
determination with respect to similar railcars in similar circumstances which
are part of the Manager's Fleet, in lieu of making the Required Modification as
provided above, Lessee may provide written notice of such determination to
Lessor in such Officer's Certificate and treat such Unit as if an Event of Loss
had occurred as of the date of such written notice with respect to such Unit and
in such event the provisions of Sections 11.2(ii), 11.3 and 11.4 shall apply
with respect to such Unit except that the amount payable under Section
11.2(ii)(a) as a result of such determination shall be an amount equal to the
greater of the Fair Market Sales Value or Stipulated Loss Amount of such Unit;
provided that there shall also be included in such Officer's Certificate a
statement of how Lessee intends to meet the financial obligations imposed under
said Sections 11.2, 11.3 and 11.4 with respect to such Units.

         Section 9.2 Optional Modifications. Lessee at any time may or may
permit a Sublessee to, in its discretion and at its own or such Sublessee's cost
and



                                       14
<PAGE>   21



expense, modify, alter or improve any Unit in a manner which is not required by
Section 9.1 (a "Modification"); provided that no Modification shall diminish the
fair market value, utility, capacity, residual value or remaining economic
useful life of such Unit below the fair market value, utility, capacity,
residual value or remaining economic useful life thereof immediately prior to
such Modification, in more than a de minimis respect, assuming such Unit was
then at least in the condition required to be maintained by the terms of this
Lease. Title to any Non-Severable Modification shall be immediately vested in
Lessor. Title to any Severable Modification (other than Required Modifications)
shall remain with Lessee or the Sublessee as applicable. If Lessee shall at its
cost cause such Severable Modifications (other than Required Modifications) to
be made to any Unit, Lessor shall have the right, upon 90 days prior written
notice in the case of the return of such Unit pursuant to Section 6.1, to
purchase any such Severable Modifications (other than Severable Modifications
consisting of proprietary or communications equipment) title to which is held by
Lessee at their then Fair Market Sales Value (taking into account their actual
condition). If Lessor does not so elect to purchase such Severable
Modifications, Lessee may remove such Severable Modifications at Lessee's cost
and expense, and if requested (which request shall be made by not less than 90
days prior written notice in the case of a return other than pursuant to Section
15.6) by Lessor will so remove such Severable Modifications at Lessee's cost and
expense, and Lessee shall, at its expense, repair any damage resulting from the
removal of any such Severable Modifications in a manner consistent with Section
8.1. If Lessee has not removed any Severable Modification prior to the return of
the related Unit as provided herein, title to such Severable Modification shall
pass to Lessor as of the date of such return.

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

         SECTION 10. Voluntary Termination.

         Section 10.1 Right of Termination. Lessee shall have the right, at its



                                       15
<PAGE>   22



option at any time or from time to time during the Basic Term on or after the
seventh anniversary of the Basic Term Commencement Date to terminate the Lease
with respect to any or all of the Units(provided that, if such termination is
for less than all Units in a Functional Group across the Partnership Fleet,
Lessee shall exercise such termination hereunder and under the comparable
provisions contained in the Other Lease (i) with respect to at least 50 railcars
in the aggregate of the type included in such Functional Group, (ii) no fewer
than 25 railcars of the type included in such Functional Group shall in the
aggregate remain subject to this Lease and the Other Lease, (iii) such
termination shall be made hereunder and under the Other Lease pro rata in
accordance with the number of units in such Functional Group subject to each
such lease and (iv) the determination as to which Units are subject to
termination shall otherwise be made by Lessee on a random basis without
discrimination based on maintenance status, operating condition of the Units in
question or otherwise) (the "Terminated Units") if (x) Lessee determines in good
faith (as evidenced by a certified copy of a resolution adopted by the General
Partner's Board of Directors and a certificate executed by the Chief Financial
Officer of the General Partner and the Chief Financial Officer of the Manager)
that such Units have become obsolete or surplus to Lessee's requirements, (y)
Lessor has received an Officer's Certificate from Lessee and the Manager to the
effect that there has been no discrimination in the selection of the Terminated
Units when measured against the other Units and the Manager's Fleet, and that,
following the termination of this Lease with respect to the Terminated Units,
the Units remaining subject to this Lease will constitute a pool of Units which
is of a sufficient quantity and quality to sustain over the remaining Basic Term
the Coverage Ratios applicable at the time of such termination and (z) Lessee
delivers at least 120 days' prior notice to Lessor and the Indenture Trustee (i)
specifying a proposed date of termination for such Units (the "Termination
Date"), which date shall be a Rent Payment Date, any such termination to be
effective on the Termination Date upon Lessee's compliance with this Section 10,
and (ii) if some but less than all of the Units in a Functional Group are
designated as Terminated Units, describing in such Officer's Certificate the
nondiscriminatory manner in which Lessee proposes to determine which Units in
that Functional Group are to be Terminated Units. Notwithstanding anything
herein contained to the contrary, there shall be no determination that a Unit is
surplus or obsolete for purposes of this Lease if, on the Termination Date, such
Unit is subject to a Sublease. Except as expressly provided otherwise herein,
there will be no conditions to Lessee's right to terminate this Lease with
respect to the Terminated Units pursuant to this Section 10.1. So long as (a)
Lessor shall not have given Lessee a notice of election to retain the Terminated
Units in accordance with Section 10.3 or (b) notice of prepayment of the
Equipment Notes shall not have been given pursuant to Section 2.10 of the
Indenture, Lessee may withdraw the termination notice referred to above at any
time prior to the 60th day prior to the scheduled Termination Date, whereupon
this Lease shall continue in full force and effect; provided that Lessee may not
exercise its right to withdraw a termination notice more than once annually or
more than four times during the Basic Term (irrespective of which Units are
covered thereby). Lessee



                                       16
<PAGE>   23



agrees that whether or not it withdraws a termination notice it will reimburse
Lessor, each Participant and the Indenture Trustee on an After Tax Basis for all
reasonable out-of-pocket costs and expenses (including reasonable legal fees and
expenses) incurred by any thereof in connection with such termination or
proposed termination.

         Section 10.2 Sale of Equipment. During the period from the date of such
notice given pursuant to Section 10.1 to the Termination Date, Lessee, as
non-exclusive agent for Lessor and, except as provided in Section 10.3, at
Lessee's sole cost and expense, shall use reasonable best efforts to obtain bids
from Persons other than Lessee or Affiliates thereof for the cash purchase of
the Terminated Units, and Lessee shall promptly, and in any event at least five
Business Days prior to the proposed date of sale, certify to Lessor in writing
the amount and terms of each such bid, the proposed date of such sale and the
name and address of the party submitting such bid. Unless Lessor shall have
elected to retain the Terminated Units in accordance with Section 10.3, on the
Termination Date: (i) Lessee shall deliver the Terminated Units (excluding any
optional Severable Modifications removed by Lessee pursuant to Section 9.2) to
the bidder (which shall not be Lessee or an Affiliate of Lessee (for the
avoidance of doubt the bidder may be a Customer, or a customer of the Manager,
and neither the Manager nor any Affiliate shall be prohibited from managing the
Units for such bidder after the purchase by such bidder)), which shall have
submitted the highest cash bid prior to such date (or to such other bidder as
Lessee and Lessor shall agree) and (ii) subject to the prior or concurrent
receipt (x) by Lessor of all amounts owing to Lessor pursuant to the next
sentence and (y) by the Persons entitled thereto of all unpaid Supplemental Rent
due on or before the Termination Date, Lessor shall, without recourse or
warranty (except as to the absence of any Lessor's Lien) simultaneously
therewith transfer all of its right, title and interest in and to the Terminated
Units to such bidder. The net proceeds of sale realized at such sale shall be
paid to and retained by Lessor and, in addition, on the Termination Date, Lessee
shall pay to Lessor (A) all Basic Rent with respect to such Terminated Units due
and payable prior to the Termination Date (exclusive of any Basic Rent due on
such date), (B) the excess, if any, of (1) the Termination Amount for the
Terminated Units computed as of the Termination Date over (2) the net cash sales
proceeds (after the deduction of all reasonable costs and expenses (including
any applicable sales, transfer or similar taxes) of Lessor and Owner Participant
in connection with such sale) of the Terminated Units, (C) an amount equal to
the Make-Whole Amount and any unpaid Late Payment Premium in respect of the
principal amount of the Equipment Notes to be prepaid in accordance with Section
2.10(a) of the Indenture and (D) all other Rent (exclusive of any Basic Rent due
on such date) then due and payable hereunder (which shall include, without
limitation, the Accumulated Equity Deficiency Amount (without duplication of
amounts calculated above) and Late Payment Interest related thereto), so that,
after receipt and application of all such payments, but without withdrawal from
any Reserve Account, Owner Participant shall be entitled under the terms of the
Collateral Agency Agreement to receive, and does receive, taking into account
all payments of Basic Rent, in respect of all such Units, the sum of the
Accumulated Equity



                                       17
<PAGE>   24



Deficiency Amount and Late Payment Interest related thereto and any other
amounts then due to Owner Participant. If no sale shall have occurred, whether
as a result of Lessee's failure to pay all of the amounts hereinabove required
or otherwise, this Lease shall continue in full force and effect with respect to
such Units and Lessee agrees to reimburse Lessor, each Participant and the
Indenture Trustee for all reasonable costs and expenses (including reasonable
legal fees and expenses) incurred by any thereof in connection therewith;
provided that if such sale shall not have occurred solely because of Lessee's
failure to pay the amounts hereinabove required, Lessee shall have no further
right to terminate this Lease with respect to such Units. Lessee, in acting as
agent for Lessor, shall have no liability to Lessor for failure to obtain the
best price, shall act in its sole discretion and shall be under no duty to
solicit bids publicly or in any particular market. Lessee's sole interest in
acting as agent shall be to use its reasonable best efforts to sell the Units at
the highest price then obtainable consistent with the terms of this Lease. Owner
Participant shall have the right, but not the obligation, to obtain bids either
directly or through agents other than Lessee.

         Section 10.3 Retention of Equipment by Lessor. Notwithstanding the
provisions of Sections 10.1 and 10.2, Lessor may irrevocably elect by written
notice to Lessee, not later than 60 days after receipt of Lessee's notice of
termination, not to sell the Terminated Units on the Termination Date, whereupon
Lessee shall (i) deliver the Terminated Units to Lessor in the same manner and
condition as if delivery were made to Lessor pursuant to Section 6.1(b) and
Section 6.2, and shall extend storage rights to the same extent as provided in
Section 6.1(c), treating the Termination Date as the termination date of the
Lease Term with respect to the Terminated Units and (ii) pay to Lessor, or to
the Persons entitled thereto, all Basic Rent and all Supplemental Rent due and
owing on the Termination Date and unpaid (exclusive of any Basic Rent due on
such date in respect of the Terminated Units, but inclusive of any Supplemental
Rent measured by the Make-Whole Amount and any unpaid Late Payment Interest in
respect of the Terminated Units), so that, after receipt and application of all
such payments, but without withdrawal from any Reserve Account, Owner
Participant shall be entitled under the terms of the Collateral Agency Agreement
to receive, and does receive, taking into account all payments of Basic Rent, in
respect of all such Units, the sum of the Accumulated Equity Deficiency Amount
and Late Payment Interest related thereto and any other amounts then due to
Owner Participant. On any Termination Date where Lessee is required to make
payments pursuant to the preceding sentence, Lessee shall pay as additional
Basic Rent (or Lessor shall pay as a refund of Basic Rent) an amount equal to
the Basic Rent Adjustment (or the absolute value of the negative Basic Rent
Adjustment) set forth on Schedule 4-B to the Participation Agreement for the
relevant Rent Payment Date. If Lessor elects not to sell the Terminated Units as
provided in this Section 10.3, then Lessor shall pay, or cause to be paid, to
the Indenture Trustee an amount equal to the product obtained by multiplying the
unpaid principal amount of the Equipment Notes outstanding on such date (after
deducting therefrom the



                                       18
<PAGE>   25



principal installment, if any, to be paid on such date) by a fraction, the
numerator of which shall be the Equipment Cost of the Terminated Units and the
denominator of which shall be the aggregate Equipment Costs of all Units then
subject to this Lease. Upon payment by Lessor of the foregoing, Lessee shall pay
to Lessor an amount of rent equal to the Make-Whole Amount and any unpaid Late
Payment Interest in respect of the principal amount of the Equipment Notes to be
prepaid together with all Basic Rent (including Basic Rent due on the
Termination Date) and Supplemental Rent due and owing; provided that unless all
such amounts shall have been paid to the Indenture Trustee on the Termination
Date, this Lease shall continue in full force and effect. If after giving the
notice referred to above Lessor shall fail to pay the amounts required pursuant
to the third sentence of this Section 10.3 and as a result thereof this Lease
shall not be terminated with respect to the Terminated Units on a proposed
Termination Date, Lessor shall (x) thereafter no longer be entitled to exercise
its election to retain such Terminated Units and (y) reimburse Lessee for any
reasonable out-of-pocket expenses (including reasonable legal fees and expenses)
incurred by it in attempting to sell the Terminated Units pursuant to Section
10.2 immediately prior to Lessor's exercise of such preemptive election, and
Lessee may at its option at any time thereafter prior to the immediately
following Rent Payment Date submit a new termination notice pursuant to Section
10.1 with respect to such Terminated Units specifying a proposed Termination
Date occurring on a Determination Date occurring not earlier than 25 days from
the date of such notice.

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

         Section 10.5 Funding of Accounts on Termination. Lessee will not
exercise a termination option under this Section 10 with respect to all of the
Units unless either (a) the full amount required to fund the Post Lease Term
Reserve Account is (upon consummation of such purchase and distribution of all
amounts required to be distributed by the Collateral Agent under the Collateral
Agency Agreement) and will be then available to the Collateral Agent to fund
such Post Lease Term Reserve Account or (b) an indemnity pursuant to Section
3.13 of the Collateral Agency Agreement has been provided.

SECTION 11. Loss, Destruction Requisition, Etc.

         Section 11.1 Event of Loss. In the event that any Unit (i) shall suffer
damage or contamination which, in Lessee's reasonable judgment (as evidenced by



                                       19
<PAGE>   26



an Officer's Certificate of Lessee to such effect, confirmed by an Officer's
Certificate of the Manager), makes repair uneconomic or renders such Unit unfit
for commercial use, (ii) shall suffer destruction which constitutes a total
loss, or shall suffer theft or disappearance (after reasonable efforts by Lessee
to locate the same) for a period exceeding 6 months (or, if earlier, the end of
the Basic Term or Renewal Term then in effect), (iii) shall be permanently
returned to the manufacturer pursuant to any patent indemnity provisions, (iv)
shall have title thereto taken or appropriated by any governmental authority,
agency or instrumentality under the power of eminent domain or otherwise or (v)
shall be taken or requisitioned for use by any governmental authority or any
agency or instrumentality thereof under the power of eminent domain or
otherwise, and such taking or requisition is for a period that exceeds the
remaining Basic Term or any Renewal Term then in effect (unless such taking or
requisition is by any governmental authority, agency or instrumentality of
Mexico or any state thereof in which case such period shall be the lesser of the
period as aforesaid or 365 days) (any such occurrence being hereinafter called
an "Event of Loss"), Lessee, in accordance with the terms of Section 11.2, shall
promptly and fully inform Lessor and the Indenture Trustee of such Event of
Loss.

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

         (i) Upon Lessee's election to perform under this clause (i) pursuant to
the above-mentioned second notice (or in the circumstances of an election
described in Section 8.1(b) with respect to any Unit), as promptly as
practicable following such election, and in any event on or before the 60th day
following such second notice (or Section 8.1(b) election), Lessee shall comply
with Section 11.4(b) and shall convey or cause to be conveyed to Lessor a
replacement unit ("Replacement Unit") to be leased to Lessee hereunder, such
Replacement Unit to be of the same car type of the same or newer model year (or
otherwise approved by Lessor, which approval shall not be unreasonably
withheld), and free and clear of all Liens (other than Permitted Liens of the
type described in clause (ii) with respect to Permitted Subleases, and in
clauses (iv) and (vii) of the definition thereof) and to have a fair market
value, utility, residual value, remaining economic useful life and condition at
least equal to the Unit so replaced (assuming such Unit was in the condition
required to be maintained by the terms of this Lease) and to be (as of the date
of conveyance)



                                       20
<PAGE>   27



then subject to a currently effective Permitted Sublease having a remaining term
of not less than one year; provided, that, if only railcars of newer age or
greater value are available for such replacement, Lessee may on one occasion
re-substitute a railcar with a value closer to or equal to that of the Unit
which originally suffered the Event of Loss or was replaced (which
re-substitution shall occur within twenty-four months of the original
replacement (but in no event within the three year period immediately preceding
the Basic Term Expiration Date) and shall comply with this Section 11 as if an
Event of Loss had occurred); provided also that, if Lessee shall elect the
option under this clause (i) but shall fail to perform its obligation to effect
such replacement under this clause (i) within the 60-day period hereinabove
provided for, then (except in the case of a failure to perform an election to
replace pursuant to Section 8.1(b)) at the end of such 60-day period Lessee
shall immediately give Lessor and the Indenture Trustee notice of such failure
and specify that Lessee shall pay to Lessor on the next succeeding Rent Payment
Date that is at least 25 days after the end of such 60-day period, or in the
case of Supplemental Rent, to the Person entitled thereto, the amounts specified
in clause (ii) below as of such next succeeding Rent Payment Date, and Lessee
shall pay such amounts on such Rent Payment Date; provided further that Lessee
shall have no right to elect replacement or re-substitution under this clause
(i) if, at the time of the notice of the Event of Loss under Section 11.2 above
or at the time such replacement or resubstitution is to occur, either (A), a
Lease Default pursuant to Section 14(a), 14(b), 14(g) or 14(h) or a Lease Event
of Default shall have occurred and be continuing or (B) sufficient cash amounts
shall not have been made available to the Collateral Agent such that all amounts
then required to be applied under Section 3.4 of the Collateral Agency Agreement
in order to satisfy the amounts referred to in clauses (1) through (11) thereof,
inclusive shall have been distributed as specified thereby; or

         (ii) on the Rent Payment Date which is not less than 25 days nor more
than 60 days following the date of notice of Lessee's election to perform under
this clause (ii), Lessee shall pay or cause to be paid to Lessor (or in the case
of Supplemental Rent, to the Persons entitled thereto) in funds of the type
specified in Section 3.5, (a) an amount equal to the Stipulated Loss Amount of
each such Unit suffering an Event of Loss or deemed Event of Loss determined as
of such Rent Payment Date, (b) all Basic Rent payable on such date in respect of
such Unit (exclusive of any Basic Rent due on such date in respect of the Unit
or Units suffering the Event of Loss), (c) any unpaid Late Payment Premium in
respect of the principal amount of the Equipment Notes to be prepaid in
accordance with Section 2.10(b) of the Indenture and (d) all other Rent
(exclusive of any Basic Rent due on such date in respect of the Unit or Units
suffering the Event of Loss) then due and payable hereunder (including, without
limitation, the Accumulated Equity Deficiency Amount (without duplication of
amounts calculated above) and Late Payment Interest related thereto) so that,
after receipt and application of all such payments, but without withdrawal from
any Reserve Account, Owner Participant shall be entitled under the terms of the
Collateral Agency Agreement to receive, and does receive, taking into account
all payments of Basic Rent in respect of such Unit, the sum of the Accumulated
Equity Deficiency Amount and Late Payment Interest related thereto and any other
amounts then due to Owner Participant, it being understood that until such
Stipulated



                                       21
<PAGE>   28



Loss Amount and such other sums are paid, there shall be no abatement or
reduction of Basic Rent on account of such Event of Loss.

         Section 11.3 Rent Termination. Upon the replacement of any Unit or
Units in compliance with Sections 11.2(i) and 11.4(b) (but only as to replaced
Units and not any Replacement Unit) or upon the payment of all sums required to
be paid pursuant to Section 11.2 in respect of any Unit or Units, the Lease Term
with respect to such Unit or Units and the obligation to pay Basic Rent for such
Unit or Units accruing subsequent to the date of payment of Stipulated Loss
Amount or date of conveyance of such Replacement Unit or Units pursuant to
Section 11.2 shall terminate; provided that Lessee shall be obligated to pay all
Rent in respect of such Unit or Units which is payable under Section 11.2 with
respect to such payment of Stipulated Loss Amount or such replacement of such
Unit or Units and in respect of all other Units then continuing to remain
subject to this Lease.

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

         (b) At the time of or prior to any replacement of any Unit or
Replacement Unit, Lessee, at its own expense, will (A) furnish Lessor with a
Bill of Sale with respect to the Replacement Unit substantially in the form
delivered pursuant to Section 4.1(g) of the Participation Agreement, (B) cause a
Lease Supplement substantially in the form of Exhibit A hereto, subjecting such
Replacement Unit to this Lease, and duly executed by Lessee, to be delivered to
Lessor for execution by the appropriate parties, it being understood that upon
such execution (x) Lessee will cause such Lease Supplement to be filed for
recordation in the same manner as provided for the original Lease Supplement in
Section 16.1 and (y) to the extent that the Indenture has not been satisfied and
discharged, Lessor shall deliver possession of the "original" counterpart of
such Lease Supplement to the Indenture Trustee, (C) so long as the Indenture
shall not have been satisfied and discharged, cause an Indenture Supplement
substantially in the form of Exhibit A to the Indenture for such Replacement
Unit, to be delivered to Lessor and to the Indenture Trustee for execution and,
upon such execution, to be filed for recordation in the same manner and within
the same time periods as provided for the original Indenture Supplement in
Section 16.1, (D) furnish Lessor with an opinion of Lessee's counsel (which may
be the General Counsel or Assistant General Counsel of Trinity), (x) to the
effect that



                                       22
<PAGE>   29



the Bill of Sale referred to in clause (A) above constitutes an effective
instrument for the conveyance of title to the Replacement Unit to Lessor, and
that legal and beneficial title to the Replacement Unit has been delivered to
Lessor and (y) describing all filings and recordings required pursuant to
Section 16 with respect to the Replacement Units, (E) furnish to Owner
Participant (and its applicable Affiliates) an agreement of Lessee to indemnify
Owner Participant (and its applicable Affiliates) against any adverse tax
consequences suffered as a result of such replacement that are not otherwise
indemnified under the Tax Indemnity Agreement, (F) furnish Lessor with an
engineer's certificate (which may be from an employee of the Manager) certifying
as to the utility, condition, model year and remaining useful life required
under clause (i) of Section 11.2, (G) furnish to Lessor and the Indenture
Trustee an Officer's Certificate certifying that the Replacement Unit has a fair
market value, utility, residual value, model year and remaining economic useful
life and condition at least equal to the Unit being replaced and is free and
clear of all Liens (other than Permitted Liens of the type described in clause
(ii) with respect to Permitted Subleases, and in clauses (iv) and (vii) of the
definition thereof), (H) furnish Lessor with an opinion from independent tax
counsel reasonably acceptable to Owner Participant to the effect that Owner
Participant should not suffer any adverse consequence as a result of such
replacement, (I) furnish Lessor with an opinion of independent transportation
counsel or in-house counsel for Manager as to the absence of Liens of record
with the STB and as to the completion of all necessary STB filings and deposits
with the Registrar General of Canada described in Section 16.1 hereof with
respect to such Replacement Unit and (J) furnish such other documents and
evidence as any Participant, Lessor or the Indenture Trustee, or their
respective counsel, may reasonably request in order to establish the
consummation of the transactions contemplated by this Section 11.4. For all
purposes hereof, (i) Lessee shall be deemed to have complied with the
requirements of this Section 11.4(b) as of the date of its delivery to Lessor,
the Participants and the Indenture Trustee of the documents and instruments
referred to in the foregoing clauses (A) through (J), signed by Lessee or its
counsel, as applicable, in due form for any required filing or recording, and
such filing or recording shall have been made if such documents and instruments
have been executed and delivered by Lessor or Indenture Trustee or both of them
in a timely manner, (ii) title to the Replacement Unit shall be deemed to have
been transferred to Lessor as of such date and (iii) upon such passage of title
thereto to Lessor the Replacement Unit shall be deemed part of the property

herein. Upon such passage of title, Lessor will transfer to Lessee, "as is" and
"where is" and without recourse or warranty (except as to Lessor's Liens), all
Lessor's right, title and interest in and to the replaced Unit, and upon such
transfer, Lessor will request in writing that the Indenture Trustee execute and
deliver to Lessee an appropriate instrument releasing such replaced Unit from
the lien of the Indenture. Lessee shall pay all reasonable out-of-pocket costs
and expenses (including reasonable legal fees and expenses) incurred by Lessor,
any Participant or the Indenture Trustee in connection with any replacement
pursuant to this Section 11.4. Lessee further agrees that, upon receipt of fully
signed counterparts of the Lease Supplement and Indenture Supplement referred to
in clauses (B) and, if applicable, (C) of the first sentence of this Section
11.4(b), it will, at its sole cost and expense, cause such documents to be filed
or recorded in the manner contemplated by Section 16.1.

         Section 11.5 Eminent Domain. In the event that during the Lease Term
the use of any Unit is requisitioned or taken by any governmental authority
under the power of eminent domain or otherwise for a period which does not
constitute an Event of Loss, all of Lessee's obligations under the Operative
Agreements, including without limitation, Lessee's obligation to pay all
installments of Basic Rent, shall continue for the duration of such
requisitioning or taking. Any amount referred to in Section 11.4(a) or in
Section 12 which is payable to Lessor shall be deposited in the related
Non-Shared Payments Account established under the Collateral Agency Agreement.

SECTION 12. Insurance.

         Section 12.1 Insurance. Lessee will at all times after delivery and
acceptance of each Unit, at its own expense, keep or cause the Insurance Manager
under the Insurance Agreement to keep such Unit insured with insurers of
recognized responsibility with a rating of at least A- by A.M. Best Company (or
a comparable rating by a nationally or internationally recognized rating group
of comparable stature) or by other insurers approved in writing by Lessor, which
approval shall not be unreasonably withheld, in amounts and against risks and
with deductibles and terms and conditions not less than the insurance, if any,
maintained by the Manager with respect to similar equipment which it owns or
leases, but in no event shall such coverage be for amounts or against risks less
than the prudent industry standard for companies engaged in leasing of railcars.
Without limiting the foregoing, Lessee will in any event:

         (a) keep each Unit insured against physical damage (which may be
accomplished pursuant to a contingent physical damage policy) in an amount not
less than the Stipulated Loss Amount attributable thereto as shown on Schedule 4
to the Participation Agreement, subject to an aggregate limit for all Units of
not less than $1,500,000 per occurrence, provided that such coverage may provide
for deductible amounts of not more than $50,000 per occurrence; and

         (b) maintain public liability insurance naming Owner Participant,
Lessor, the Trust Company, the Indenture Trustee and Loan Participant as
additional insureds (but only with respect to liability arising out of or
related to the Operative Agreements and the Units) against bodily injury, death
or property damage arising out of the use or operation of the Units with general
and excess liability limits of not less than $100,000,000 per occurrence or in
the aggregate, provided that such coverage may provide for deductible amounts
not exceeding the lesser of (w) $10,000,000 or (x) the difference (not less than
zero (0)) between (i) the level of the then current deductible maintained by
Manager for the Manager's Fleet (or if Manager, its successors and assigns is no
longer engaged in the railcar leasing business, the average level of the then
current deductible amounts maintained by the three largest companies engaged in
such business in the United States) and (ii) such amount of additional coverage
as may be obtained by Lessee in reduction of the then current deductible
maintained by Manager for an additional incremental annual premium payable by
Lessee in the aggregate in respect of the entire Partnership Fleet of up to
$100,000 as adjusted by the Inflation Factor; provided, further, that such
policies which are carried on a "claims made" basis shall provide for a
retroactive date not



                                       24
<PAGE>   31



more recent than either (y) the Closing Date, or (z) a date seven years prior to
the effective date of the policy.

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

         (d) If Lessee or the Insurance Manager shall maintain any liability
coverages for the benefit of Lessee in excess of the coverages required
hereunder (whether or not such excess coverage complies with the requirements
under this Section 12), Lessee will cause all such coverages to name Owner
Participant, Lessor, the Trust Company, the Indenture Trustee and Loan
Participant as additional insureds (but only with respect to liability arising
out of or related to the Operative Agreements or the Units), provided, however,
that, the requirements of this Section 12 shall not otherwise apply to such
coverages.

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

         (b) In lieu of maintaining the physical damage insurance required by
Section 12.1(a), Lessee may self-insure with respect to the Units for such
amounts and against such risks as shall be consented to by Lessor and the
Indenture Trustee, which consent shall be based upon reasonable practices then
in effect in the railcar leasing and insurance industries and upon the financial
condition of Lessee taking into account Lessee's capital structure and that
Lessee is a special purpose corporation.

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

         (i)      to Lessee promptly following receipt by the Indenture Trustee
                  or Lessor, as the case may be, of a written application signed
                  by Lessee for payment to Lessee for repairing or restoring the
                  Units which have been damaged so long as (1) Lessee



                                       25
<PAGE>   32



                  shall have complied with the applicable provisions of this
                  Lease, and (2) Lessee shall have certified that any damage to
                  such Units shall have been fully repaired or restored; or

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

         Section 12.3 Public Liability Insurance. (a) The public liability
insurance referred to in paragraph 12.1(b) shall (i) provide that in as much as
such policies cover more than one insured, all terms, conditions, insuring
agreements and endorsements, with the exception of limits of liability,
deductibles or retentions and liability for premiums, commissions, assessments
or calls (which shall be solely a liability of Lessee), shall operate in the
same manner as if there were a separate policy or policies covering each
insured, (ii) waive any rights of subrogation of the insurers against Owner
Participant, Lessor, the Trust Company, the Indenture Trustee, and Loan
Participant (iii) provide that neither Owner Participant, Lessor, the Trust
Company, the Indenture Trustee nor Loan Participant shall have any
responsibility for any insurance premiums, whether for coverage before or after
cancellation or termination of any such policies as to Lessee and (iv) be
primary without contribution from any similar insurance maintained by Owner
Participant, Lessor, the Trust Company, the Indenture Trustee or Loan
Participant.

         (b) Lessee shall use its reasonable efforts to obtain public liability
insurance policies which stipulate that coverage thereunder will not be
invalidated (as to Owner Participant, Loan Participant, Lessor, as Lessor of the
Units and in its individual capacity, and the Indenture Trustee) by any act or
neglect of Lessee, or any breach or violation by Lessee of any warranties,
declarations or conditions contained in such policies, but shall be under no
obligation to obtain such policies containing such stipulations if they are not
available to Lessee at commercially reasonable rates in the markets in which
Lessee has then placed its insurance program.

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



                                       26
<PAGE>   33



insurance premiums for the coverage required by Section 12.1 (b) for the
immediately preceding fiscal year; and in the event that any such certificate is
not received by Lessor within such 15-day period, any such waiver shall be
deemed revoked. At any time after the granting of such waiver, but not more
often than once a year, Lessor may make a written request for a supplemental
report (in form reasonably acceptable to Lessor) from such insurance advisor(s)
updating the prior report and reaffirming the conclusions set forth therein.
Lessee shall provide any such required supplemental report within 60 days after
receipt of the written request therefor. Any such waiver shall be effective for
only as long as such insurance is not reasonably available to Lessee in the
commercial markets in which Lessee normally purchases its insurance at
commercially reasonable rates, it being understood that the failure of Lessee to
furnish timely any such supplemental report shall be conclusive evidence that
such condition no longer exists. If such supplemental report shows that such
coverage is available, Lessee shall within 90 days of such report obtain such
insurance coverage. During any period with respect to which such waiver has been
granted and remains in effect under this Section 12.3(c), Lessee shall obtain
public liability insurance as set forth in Section 12.1(b) from such carriers,
in such amounts and with coverage limits and deductibles as may be reasonable in
its judgment under the circumstances, but in any event (i) no less than prudent
industry standards and (ii) in an amount that may be purchased for a premium
equal to 200% of Lessee's cost (on a fleet-wide basis) of public liability
insurance premiums for the coverage on a fleet-wide basis required by Section
12.1(b) for the final year immediately preceding the fiscal year in which such
waiver first was granted.

         Section 12.4 Certificate of Insurance. (a) Lessee shall, prior to the
Closing Date and when the renewal certificate referred to below is sent (but in
any event not less than annually), furnish (or, in the case of (iii) below, use
reasonable efforts to furnish) Lessor, the Indenture Trustee, Owner Participant
and the Loan Participant with a certificate signed by the insurer or an
independent insurance broker (i) showing the insurance then maintained by Lessee
pursuant to Section 12.1, (ii) stating that, except as noted in such
certificate, such insurance complies with the requirements contained in Exhibit
B-1 (as to public liability insurance) and/or B-2 (as to physical/damage
insurance) to the Participation Agreement, (iii) stating that, except as noted
in such certificate, such insurance complies with the requirements contained in
this Section 12 and (iv) to the extent that any provision that Lessee is
required to use reasonable efforts to obtain is not contained in such insurance,
such certificate shall so state and shall confirm that, in such broker's
opinion, such provision is not reasonably obtainable. Lessor shall be entitled
at its expense to review copies of all applicable insurance policies. With
respect to any renewal policy or policies, certificates or binders evidencing
such renewal shall be furnished as soon as practicable, but in no event later
than 30 days after the earlier of the date such renewal is effected or the
expiration date of the original policy or policies. Simultaneously, with the
furnishing of such certificate, Lessee will provide appropriate evidence,
reasonably satisfactory to Lessor and the Indenture Trustee, that all premiums
due on such insurance have been paid.



                                       27
<PAGE>   34



         (b) Lessee agrees to use reasonable efforts to cause each of its
insurers to agree that, with respect to any policy of insurance maintained
pursuant to Section 12.1, such insurer will provide not less than 30 days' prior
written notice to Lessor, the Indenture Trustee, Loan Participant and Owner
Participant of any non-renewal or material adverse change with respect to such
policy. For purposes of this Section 12.4(b), "material adverse change" shall
mean a material adverse change in policy limits, exclusions or deductibles or
any material adverse change in policy coverage inconsistent with the
requirements of Section 12.1(b). If any of Lessee's insurers delivers such
notice of non-renewal, Owner Participant may attempt to obtain and provide
satisfactory insurance and Lessee shall reimburse Owner Participant for
reasonable and prudent expenses incurred (i) during the period 10 days prior to
expiration of existing insurance policies, for all Owner Participant's expenses
excluding broker fees and commissions and insurance premiums, and (ii) on and
after the expiration of existing insurance policies, for all Owner Participant's
expenses including broker fees and commissions and insurance premiums.

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

         Section 12.6 Post-Lease Term Insurance. Lessee agrees that upon the
expiration or earlier termination of the Lease Term, Lessee will, with respect
to the public liability insurance otherwise required to be carried under this
Section 12,



                                       28
<PAGE>   35



either: (A) purchase a seven year extended reporting period for Owner
Participant, Lessor and Owner Trustee, or (B) obtain the written agreement of
the Manager in form and substance satisfactory to Owner Participant to carry or
cause to be carried for such seven year period public liability insurance which
satisfies the requirements of this Section 12 and which names Owner Participant,
Lessor, the Collateral Agent and Owner Trustee as additional insureds.

SECTION 13. Reports; Inspection.

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

         Section 13.2 Lessor's Inspection Rights. Lessor, Owner Participant and
the Indenture Trustee each shall have the right, but not the obligation, at
their respective sole cost and expense, unless a Lease Event of Default shall
have occurred and be continuing, by their respective authorized representatives,
to inspect the Units, all subleases thereof and Lessee's records with respect
thereto. All inspections shall be conducted during Lessee's normal business
hours, on the Manager's premises or in areas that are not the premises of a
Sublessee to which Lessee has reasonable access, and upon reasonable prior
notice to Lessee. Lessee shall not be liable for any injury to, or the death of,
any Person exercising, either on behalf of Lessor, Owner



                                       29
<PAGE>   36



Participant, the Indenture Trustee or any prospective user, the rights of
inspection granted under this Section 13.2 unless caused by Lessee's gross
negligence or willful misconduct. Except following the occurrence and
continuance of a Lease Event of Default, no inspection pursuant to this Section
13.2 shall interfere with the use, operation or maintenance of the Units or the
ordinary course of Lessee's or any Sublessee's business, and except as provided
herein, Lessee shall not be required to undertake or incur any additional
liabilities in connection therewith.

SECTION 14. Lease Events of Default.

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

         (a) Lessee shall fail to (i) make or (ii) be deemed by virtue of the
last sentence of Section 3.5 hereof to have made any payment of Basic Rent,
Early Purchase Price, any other purchase price to be paid by Lessee for any
Units pursuant to this Lease or the Participation Agreement, Stipulated Loss
Amount or Termination Amount within 10 Business Days after the same shall have
become due; provided, however, that so long as any Equipment Notes remain
outstanding, failure to make (or be deemed to have made) any portion of Basic
Rent on any Rent Payment Date shall not be a Lease Event of Default so long as
the amounts applied under Section 3.4, clause (4), of the Collateral Agency
Agreement are sufficient to make the distributions required under such clause
(4) with respect to the obligations owed under this Lease; or

         (b) Lessee shall fail to (i) make or (ii) be deemed by virtue of
payments made by the Collateral Agent to have made any payment of Supplemental
Rent; including indemnity or tax indemnity payments, but not including
Stipulated Loss Amount, Termination Amount, Early Purchase Price, or any other
purchase price to be paid by Lessee for any Units pursuant to this Lease or the
Participation Agreement after the same shall have become due and such failure
shall continue unremedied for 10 Business Days after receipt by Lessee of
written notice of such failure from Lessor, Owner Participant or the Indenture
Trustee; provided, however, that so long as any Equipment Notes remain
outstanding, failure to make (or be deemed to have made) payment of any of the
amounts referred to in or to be applied pursuant to clauses (5) through (14) of
Section 3.4 of the Collateral Agency Agreement shall not be a Lease Event of
Default; or

         (c) Lessee shall fail to maintain in effect the insurance required by
Section 12 or Section 6.4 of the Collateral Agency Agreement and such failure
shall not have been waived as provided for therein; or



                                       30
<PAGE>   37



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

         (e) Lessee shall fail to observe or perform in any material respect any
of the covenants or agreements to be observed or performed by Lessee in Section
6.2 or 6.3 of the Collateral Agency Agreement; or

         (f) Any representation or warranty made by Lessee in any Lessee
Agreement or any representation or warranty made by TILC or TRMI in any
Operative Agreement to which any such Person is a party is untrue or incorrect
in any material respect as of the date of making thereof and such untruth or
incorrect-ness shall continue to be material and unremedied; provided that, if
such untruth or incorrectness is capable of being remedied, no such untruth or
incorrectness shall constitute a Lease Event of Default hereunder for a period
of 30 days after receipt of notice from Lessor, Owner Participant or the
Indenture Trustee so long as Lessee, TILC or TRMI, as the case may be, is
diligently proceeding to remedy such untruth or incorrectness and shall in fact
remedy such untruth or incorrectness within such period; provided that such
untrue or incorrect representation or warranty shall be deemed to be remediable
or remedied only after all adverse consequences thereof, if any, can be and have
been remedied as applicable; or

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

         (h) An involuntary case or other proceeding shall be commenced against
Lessee or the General Partner seeking liquidation, reorganization or other
relief with respect to it or its debts under any bankruptcy, insolvency or other
similar law now or hereafter in effect, or seeking the appointment of a trustee,
receiver,



                                       31
<PAGE>   38



liquidator, custodian or other similar official of it or any substantial part of
its property, and such involuntary case or other proceeding shall remain
undismissed and unstayed for a period of 60 days; or

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

         (j) A Manager Default shall have occurred and be continuing under the
Management Agreement, and Lessee shall have failed to exercise its rights under
the Management Agreement in respect of such Manager Default for a period of 30
days after receipt by Lessee of written notice from Lessor, Owner Participant or
the Indenture Trustee demanding that such action be taken; or

         (k) An Insurance Manager Default shall have occurred and be continuing
under the Insurance Agreement, and Lessee shall have failed to exercise its
rights under the Insurance Agreement in respect of such Insurance Manager
Default for a period of 30 days after receipt by Lessee of written notice from
Lessor, Owner Participant or the Indenture Trustee demanding that such action be
taken;

         (1) The Administrator shall have defaulted in any material respect in
the performance of any of its obligations under the Administrative Services
Agreement, and Lessee shall have failed to exercise its rights under the
Administrative Services Agreement in respect of such default for a period of 30
days after receipt by Lessee of written notice from Lessor, Owner Participant or
the Indenture Trustee , demanding that such action be taken; or

         (m) A "Lease Event of Default" (as defined in the Other Lease) shall
have occurred and be continuing with respect to the Other Lease.

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

SECTION 15. Remedies.

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

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

         (b) by notice in writing to Lessee, Lessor may demand that Lessee, and
Lessee shall, upon written demand of Lessor and at Lessee's expense (but subject
to the rights of any Sublessee which has been granted the right of quiet
enjoyment of the Unit by Lessee pursuant to a Sublease, so long as no event of
default by the Sublessee shall have occurred and be continuing under the
relevant Sublease), (i) forthwith return all or any part of the Units so
demanded to Lessor or its order in the manner and condition required by, and
otherwise in accordance with all of the provisions of, Section 15.5; or Lessor
with or without notice or judicial process may by its agents enter upon the
premises of Lessee or other premises where any of the Units may be located and
take possession of and remove all or any of the Units , and Lessor may use and
employ in connection with such removal any services, aids, equipment, trackage
and other facilities of Lessee as is reasonably required to remove such Units
and thenceforth hold, possess and enjoy the same free from any right of Lessee,
or its successor or assigns, to use such Units for any purpose whatever and (ii)
with respect to any Unit which is then subject to a Sublease, assign all of
Lessee's right, title and interest in such Sublease to Lessor;

         (c) sell any Unit and/or assign any Sublease at public or private sale
in such manner as Lessor may determine, free and clear of any rights of Lessee
(but subject to the rights of any Sublessee which has been granted the right of
quiet enjoyment of the Unit by Lessee pursuant to a Sublease, so long as no
event of default by the Sublessee shall have occurred and be continuing under
the relevant Sublease) and without any duty to account to Lessee or any
Sublessee with respect to such sale or for the proceeds thereof (except to the
extent required by paragraph (f) below if Lessor elects to exercise its rights
under said paragraph), in which event Lessee's obligation to pay Basic Rent with
respect to such Unit hereunder due for any periods subsequent to the date of
such sale shall terminate (except to the extent that Basic Rent is to be
included in computations under paragraph (e) or (f) below if Lessor elects to
exercise its rights under either of said paragraphs);



                                       33

         (d) hold, keep idle or lease to others any Unit not then subject to a
Sublease as Lessor in its sole discretion may determine, free and clear of any
rights of Lessee and without any duty to account to Lessee or any Sublessee with
respect to such action or inaction or for any proceeds with respect thereto,
except that Lessee's obligation to pay Basic Rent with respect to such Unit due
for any periods subsequent to the date upon which Lessee shall have been
deprived of possession and use of such Unit pursuant to this Section 15 shall be
reduced by the net proceeds, if any, received by Lessor from leasing such Unit
to any Person other than Lessee;

         (e) whether or not Lessor shall have exercised, or shall thereafter at
any time exercise, any of its rights under paragraph (a), (b), (c) or (d) above
with respect to any Unit, Lessor, by written notice to Lessee specifying a
payment date (which date shall be a Determination Date for the purposes of
computing Stipulated Loss Amount) which shall be not less than 10 days after the
date of such notice, may demand that Lessee pay to Lessor, and Lessee shall pay
to Lessor, on the payment date specified in such notice, as liquidated damages
for loss of a bargain and not as a penalty (in lieu of the Basic Rent for such
Unit due after the payment date specified in such notice), all Rent, other than
Stipulated Loss Amount and Termination Amount or amounts calculated by reference
thereto, due and payable, or accrued, in respect of such Unit as of the payment
date specified in such notice (exclusive of any Basic Rent due on such date)
plus whichever of the following amounts Lessor, in its sole discretion, shall
specify in such notice: (i) an amount with respect to each such Unit which
represents the excess of the present value, as of such payment date, of all
rentals for such Unit which would otherwise have accrued hereunder from such
payment date for the remainder of the Basic Term or any Renewal Term then in
effect over the then present value of the then Fair Market Rental Value of such
Unit (taking into account its actual condition) for such period discounted from
the end of such Term to such payment date, such present value to be computed in
each case using a per annum discount rate equal to the Debt Rate, compounded
monthly from the respective dates upon which rentals would have been payable
hereunder had this Lease not been terminated; or (ii) an amount equal to the
excess, if any, of the Stipulated Loss Amount for such Unit computed as of the
payment date specified in such notice over the Fair Market Sales Value of such
Unit (taking into account its actual condition) as of the payment date specified
in such notice; or (iii) if Lessor shall not have sold such Unit pursuant to the
exercise of its rights under paragraph (c) above with respect to such Unit, an
amount equal to the higher of Stipulated Loss Amount for such Unit computed as
of the payment date specified in such notice or the Fair Market Sales Value of
such Unit (assuming it is in the condition required by this Lease) as of the
payment date specified in such notice; and upon payment by Lessee pursuant to
said clause (iii) of such Stipulated Loss Amount or Fair Market Sales Value, as
the case may be, any Late Payment Premium and of all other amounts (other than
Basic Rent due on such date) payable by Lessee under this Lease and under the
other Operative Agreements in respect of such Unit, Lessor shall



                                       34
<PAGE>   41



transfer "as is" and "where is" and without recourse or warranty all right,
title and interest of Lessor in and to such Unit to Lessee or as it may direct,
and Lessor shall execute and deliver such documents evidencing such transfer as
Lessee shall reason-ably request;

         (f) if Lessor shall have sold any Unit pursuant to paragraph (c) above,
Lessor, in lieu of exercising its rights under paragraph (e) above with respect
to such Unit may, if it shall so elect, demand that Lessee pay to Lessor, and
Lessee shall pay to Lessor, as liquidated damages for loss of a bargain and not
as a penalty (in lieu of the Basic Rent for such Unit due subsequent to the Rent
Payment Date next preceding such sale), any accrued and unpaid Rent for such
Unit as of the date of such sale (Basic Rent for this purpose accruing at a per
diem rate equal to the monthly amount due on the next following Rent Payment
Date divided by 30) (exclusive of any Basic Rent due on such date), plus the
amount, if any, by which the Stipulated Loss Amount of such Unit computed as of
the Rent Payment Date next preceding the date of such sale or, if such sale
occurs on a Rent Payment Date, then computed as of such Rent Payment Date, plus
the amount of any Late Payment Premium, exceeds the net proceeds of such sale
(taking into account for this purpose all costs and expenses, including legal
fees and expenses, incurred by Lessor in connection with such sale or otherwise
exercising remedies hereunder) plus interest on such excess from the date of
such sale to the date of payment at the Late Rate; and

         (g) Lessor may terminate the leasing of any or all Units under this
Lease and/or any Sublease (except with respect to a Sublease which grants the
Sublessee thereunder the right of quiet enjoyment with respect to the Unit, so
long as no event of default by the Sublessee shall have occurred and be
continuing under the relevant Sublease) or may exercise any other right or
remedy that may be available to it under applicable law.

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

         In the event Lessor terminates this Lease pursuant to any provision of
this Section 15.1, and the Stipulated Loss Amount is not payable, the amounts
otherwise payable by Lessee hereunder shall be increased by any positive amount
(as a payment for accrued but unpaid Basic Rent) of the Basic Rent Adjustment
set forth on Schedule 4-A of the Participation Agreement opposite the relevant
Rent Payment Date or decreased by the absolute value of any negative amount (as
a rebate of prepaid Basic Rent) of the Basic Rent Adjustment set forth on
Schedule 4-A of the Participation Agreement opposite the relevant Rent Payment



                                       35
<PAGE>   42



Date; provided, however, that to the extent that such payment or refund does not
precisely reflect the difference between Basic Rent allocated and Basic Rent
paid as of the date Basic Rent ceases to accrue, the amounts due hereunder shall
be further adjusted to ensure that the aggregate amount of Basic Rent paid
equals the aggregate amount of Basic Rent allocated as of the date Basic Rent
ceases to accrue.

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

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

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

         Section 15.5 Lessee's Duty to Return Equipment Upon Default. If Lessor
or any assignee of Lessor shall terminate this Lease pursuant to this Section



                                       36
<PAGE>   43



15 and shall have provided to Lessee the written demand specified in Section
15.1(b), Lessee shall forthwith deliver possession of the Units not then subject
to a Sublease to Lessor (except where Lessor has received all amounts payable by
Lessee pursuant to any notice provided by Lessor under Section 15.1(e)(iii)).
For the purpose of delivering possession of any Unit not then subject to a
Sublease to Lessor as above required, Lessee shall at its own cost, expense and
risk (except as hereinafter stated):

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

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

         (c) transport the Units to any place on any lines of railroad or to any
connection carrier for shipment, all as Lessor may direct in writing. All such
Units not then subject to a Sublease returned shall be in the condition required
by Section 6.2 hereof.

         All amounts earned in respect of the Units after the date of
termination of this Lease pursuant to this Section 15, but not exceeding amounts
actually received therefor, shall be paid to Lessor or, so long as the Indenture
shall not have been discharged pursuant to its terms, the Indenture Trustee,
and, if received by Lessee, shall be promptly turned over to Lessor or the
Indenture Trustee as aforesaid. In the event any Unit not then subject to a
Sublease is not assembled, delivered and stored as hereinabove provided within
15 days after the termination of the leasing of such Unit pursuant to Section
15, Lessee shall, in addition, pay to Lessor or the Indenture Trustee as
aforesaid as liquidated damages and not as a penalty, for each day thereafter an
amount equal to the amount, if any, by which the daily equivalent of the average
Basic Rent for the term in effect immediately prior to the expiration of the
Lease for such Unit exceeds the amount, if any, received by Lessor or the
Indenture Trustee as aforesaid (either directly or from Lessee) for such day for
such Unit pursuant to the preceding sentence.

         Section 15.6 Specific Performance; Lessor Appointed Lessee's Agent. The
assembling, delivery, storage and transporting of the Units not then subject to
a Sublease as provided in Section 15.5 are of the essence of this Lease, and
upon application to any court of equity having jurisdiction in the premises,
Lessor shall be entitled to a decree against Lessee requiring specific
performance of the covenants of Lessee so to assemble, deliver, store and
transport the Units not then subject to a Sublease. Without in any way limiting
the obligation of Lessee under the provisions



                                       37
<PAGE>   44



of Section 15.5, Lessee hereby irrevocably appoints Lessor as the agent and
attorney of Lessee, with full power and authority, at any time while Lessee is
obligated to deliver possession of any Units not then subject to a Sublease to
Lessor pursuant to this Section 15, to demand and take possession of such Unit
in the name and on behalf of Lessee from whosoever shall be at the time in
possession of such Unit.

SECTION 16. Filings; Further Assurances.

         Section 16.1 Filings. This Lease or a counterpart or copy hereof or
evidence hereof may be filed or recorded in any public office in the United
States as may be necessary or appropriate to protect the interest of Lessor,
Owner Participant or the Indenture Trustee herein or in the Units. On or prior
to the Closing Date Lessee will (i) cause a memorandum of each of this Lease,
the Lease Supplements dated the Closing Date, the TILC Bill of Sale, the Bill of
Sale, the TILC Assignment, the Assignment, the Collateral Agency Agreement, the
Indenture and the Indenture Supplements dated the Closing Date (x) to be duly
filed and recorded with the STB in accordance with 49 U.S.C. Section 11301 and
(y) to be deposited with the Registrar General of Canada pursuant to Section 105
of the Canada Transportation Act (and all necessary actions shall have been
taken for publication of such deposit in the Canada Gazette in accordance with
said Section 105), (ii) cause precautionary UCC-1 financing statements to be
filed in appropriate jurisdictions as reasonably requested by Lessor naming
Lessor as "lessor" and Lessee as "lessee" of the Equipment and (iii) will
furnish Lessor, the Indenture Trustee and Owner Participant proof thereof.
Notwithstanding the foregoing, in no event shall Lessee or any of its Affiliates
be required to take any action to perfect any security interest which any Person
may have in any Sublease, other than the filing of a UCC-1 Financing Statement
against the Partnership in the jurisdiction in which the Partnership's chief
executive office is located and in the Partnership's jurisdiction of formation
covering all Subleases generally.

         Section 16.2 Further Assurances. Lessee will duly execute and deliver
to Lessor such further documents and assurances and take such further action as
Lessor may from time to time reasonably request or as may be required by
applicable law or regulation in order to effectively carry out the intent and
purpose of this Lease and to establish and protect the rights and remedies
created or intended to be created in favor of Lessor, the Participants and the
Indenture Trustee hereunder, including, without limitation, the execution and
delivery of supplements or amendments hereto, in recordable form, subjecting to
this Lease any Replacement Unit and the recording or filing of counterparts
hereof or thereof or Uniform Commercial Code financing statements in accordance
with the laws of such jurisdiction as Lessor may from time to time deem
advisable; provided, that in no event shall Lessee or any of its Affiliates be
required to take any action to perfect any security interest which any Person
may have in any Sublease, other than the filing of a UCC-1 Financing Statement
against the Partnership in the jurisdiction in which the Partnership's chief
executive office is



                                       38
<PAGE>   45



located and in the Partnership's jurisdiction of formation covering all
Subleases generally.

         Section 16.3 Other Filings. If, at any time after the Closing Date and
during the Lease Term, Mexico, or one or more states in Mexico, establishes a
state or other system for filing and perfecting the ownership and/or security
interests of entities such as Lessor and/or the Indenture Trustee, at the time
that Lessee or the Manager takes such action with respect to other equipment
similar to the Units (whether owned or leased by Lessee) and also upon the
request of Lessor, any Participant, or the Indenture Trustee, Lessee shall cause
any and all of the Operative Agreements to be recorded with or under such system
and shall cause all other filings and recordings and all such other action
required under such system to be effected and taken, in order to perfect and
protect the respective right, title and interests of Lessor, Owner Participant,
Loan Participant and the Indenture Trustee; provided, that in no event shall
Lessee or any of its Affiliates be required to take any action to perfect any
security interest which any Person may have in any Sublease.

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

SECTION 17. Lessor's Right to Perform.

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

SECTION 18. Assignment.

         Section 18.1 Assignment by Lessor. Lessee and Lessor hereby confirm
that concurrently with the execution and delivery of this Lease, Lessor has
executed and delivered to the Indenture Trustee the Indenture, which assigns as
collateral security and grants a security interest in favor of the Indenture
Trustee in, to and



                                       39
<PAGE>   46



under this Lease and certain of the Rent payable hereunder (excluding Excepted
Property), all as more explicitly set forth in the Indenture. Lessor agrees that
it shall not otherwise assign or convey its right, title and interest in and to
this Lease or any Unit, except as expressly permitted by and subject to the
provisions of the Participation Agreement, the Trust Agreement and the
Indenture.

         Section 18.2 Assignment by Lessee. Except in the case of any
requisition for use by any governmental authority or any agency or
instrumentality thereof referred to in Section 11.1, Lessee will not, except as
expressly permitted in the Operative Agreements, without the prior written
consent of Lessor and the Indenture Trustee, assign any of its rights hereunder.

         Section 18.3 Sublessee's or Others Performance and Rights. Any
obligation imposed on Lessee in this Lease shall require only that Lessee
perform or cause to be performed such obligation, even if stated herein as a
direct obligation, and the performance of any such obligation by the Manager
under the Management Agreement, the Insurance Manager under the Insurance
Agreement or any Sublessee under a Sublease then in effect and permitted by the
terms of this Lease shall constitute performance by Lessee and discharge such
obligation by Lessee. Except as otherwise expressly provided herein, any right
granted to Lessee in this Lease shall grant Lessee the right to (a) exercise
such right or permit such right to be exercised by the Manager or the Insurance
Manager or (b) in Lessee's capacity as sublessor pursuant to any Permitted
Sublease permit any Sublessee to exercise substantially equivalent rights under
any such sublease as are granted to Lessee under this Lease; provided, however,
that Lessee's right to terminate this Lease pursuant to Section 10 and Lessee's
purchase and renewal options set forth in Section 22 may be exercised only by
Lessee; provided, further, that nothing in this Section 18.3 shall or shall be
deemed to (i) create any privity of contract between any such Sublessee, on the
one hand, and any of Lessor, Owner Participant or any subsequent transferee or
Affiliate of any such Person, on the other hand, (ii) create any duty or other
liability of any nature whatsoever on the part of any of Lessor, Owner
Participant or any subsequent transferee or Affiliate of any such Person, to any
such Sublessee or any Affiliate thereof or (iii) modify or waive any term or
provision of Section 8.3 hereof, which Section 8.3 shall control if any conflict
arises between any of the provisions thereof and this Section 18.3. The
inclusion of specific references to obligations or rights of any such Sublessee
in certain provisions of this Lease shall not in any way prevent or diminish the
application of the provisions of the two sentences immediately preceding with
respect to obligations or rights in respect of which specific reference to any
such Sublessee has not been made in this Lease.

SECTION 19. Net Lease, Etc.

         This Lease is a net lease and Lessee's obligation to pay all Rent
payable hereunder shall be absolute, unconditional and irrevocable and shall not
be affected



                                       40
<PAGE>   47



by any circumstance of any character including, without limitation, (i) any
set-off, abatement, counterclaim, suspension, recoupment, reduction, rescission,
defense or other right that Lessee may have against Lessor, Owner Participant,
the Indenture Trustee or any holder of an Equipment Note or Pass Through
Certificate, any vendor or manufacturer of any Unit, or any other Person for any
reason whatsoever, (ii) any defect in or failure of title, merchantability,
condition, design, compliance with specifications, operation or fitness for use
of all or any part of any Unit, (iii) any damage to, or removal, abandonment,
requisition, taking, condemnation, loss, theft or destruction of all or any part
of any Unit or any interference, interruption, restriction, curtailment or
cessation in the use or possession of any Unit by Lessee or any other Person for
any reason whatsoever or of whatever duration, (iv) any insolvency, bankruptcy,
reorganization or similar proceeding by or against Lessee, Lessor, Owner
Participant, the Indenture Trustee, Loan Participant, any holder of an Equipment
Note or Pass Through Certificate or any other Person, (v) the invalidity,
illegality or unenforceability of this Lease, any other Operative Agreement, or
any other instrument referred to herein or therein or any other infirmity herein
or therein or any lack of right, power or authority of Lessee, Lessor, Owner
Participant, the Indenture Trustee, any holder of an Equipment Note or Pass
Through Certificate or any other Person to enter into this Lease or any other
Operative Agreement or to perform the obligations hereunder or thereunder or
consummate the transactions contemplated hereby or thereby or any doctrine of
force majeure, impossibility, frustration or failure of consideration, (vi) the
breach or failure of any warranty or representation made in this Lease or any
other Operative Agreement by Lessee, Lessor, Owner Participant, Loan
Participant, the Indenture Trustee, any holder of an Equipment Note or Pass
Through Certificate or any other Person, (vii) the requisitioning, seizure or
other taking of title to or use of such Unit by any government or governmental
authority or otherwise, whether or not by reason of any act or omission of
Lessor, Lessee or the Indenture Trustee, or any other deprivation or limitation
of use of such Unit in any respect or for any length of time, whether or not
resulting from accident and whether or not without fault on the part of Lessee
or (viii) any other circumstance or happening whatsoever, whether or not similar
to any of the foregoing. To the extent permitted by applicable law, Lessee
hereby waives any and all rights which it may now have or which at any time
hereafter may be conferred upon it, by statute or otherwise, to terminate,
cancel, quit or surrender this Lease with respect to any Unit, except in
accordance with the express terms hereof. If for any reason whatsoever this
Lease shall be terminated in whole or in part by operation of law or otherwise,
except as specifically provided herein, Lessee nonetheless agrees, to the
maximum extent permitted by law, to pay to Lessor or to the Indenture Trustee,
as the case may be, an amount equal to each installment of Basic Rent and all
Supplemental Rent due and owing, at the time such payment would have become due
and payable in accordance with the terms hereof had this Lease not been
terminated in whole or in part. Each payment of Rent made by Lessee hereunder
shall be final and Lessee shall not seek or have any right to recover all or any
part of such payment from Lessor or any Person for any reason whatsoever.
Nothing contained



                                       41
<PAGE>   48



herein shall be construed to waive any claim which Lessee might have under any
of the Operative Agreements or otherwise or to limit the right of Lessee to make
any claim it might have against Lessor or any other Person or to pursue such
claim in such manner as Lessee shall deem appropriate.

SECTION 21. Concerning the Indenture Trustee.

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

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

SECTION 22. Purchase Options; Renewal Options.

         Section 22.1 Early Purchase Option. In addition to the option granted
Lessee pursuant to Section 6.9 of the Participation Agreement and provided that
Lessee shall have duly given the notice required by the next succeeding sentence
and the corresponding notice under the Other Lease and shall concurrently
purchase all (but not less than all) of the units then subject to the Other
Lease, Lessee shall have the right and, upon the giving of such notice, the
obligation to purchase all (but not less than all) of the Units leased hereunder
(as specified in such notice) on the Early Purchase Date for such Units at a
price equal to the Early Purchase Price of such Units plus the other amounts
specified below. Lessee shall give Lessor written notice not less than 90 days
and not more than 180 days prior to the Early Purchase Date of its election to
exercise the purchase option provided for in this Section 22.1, which notice
shall be irrevocable. Payment of the Early Purchase Price, together with (w) all
unpaid Basic Rent therefor due and payable, or accrued, prior to the Early
Purchase Date, (x) any Make-Whole Amount and Late Payment Interest with respect
to the Equipment Notes then being prepaid, (y) the Accumulated Equity Deficiency
Amount (without duplication of amounts calculated above) and any Late Payment
Interest related thereto and (z) any other Supplemental Rent due and owing by
Lessee under the Operative Agreements (so that, after receipt and application of



                                       43
<PAGE>   50



all such payments, but without withdrawal from any Reserve Account, Owner
Participant shall be entitled under the terms of the Collateral Agency Agreement
to receive, and does receive, taking into account all payments of Basic Rent in
respect of the Units, the sum of the Accumulated Equity Deficiency Amount and
Late Payment Interest related thereto and any other amounts then due to Owner
Participant) shall be made on the Early Purchase Date at the place of payment
specified in Section 3.5 hereof in immediately available funds against delivery
of a bill of sale transferring and assigning to Lessee all right, title and
interest of Lessor in and to such Units on an "as-is" "where-is" basis and
containing a warranty as to the absence of Lessor's Liens. Lessor shall not be
required to make any other representation or warranty as to the condition of
such Units or any other matters, and may specifically disclaim any such
representations or warranties. The costs of preparing the bill of sale and all
other documentation relating to any purchase by Lessee pursuant to this Section
22.1 and the costs of all necessary filings relating to such purchase will be
borne by Lessee. In the event of any such purchase and receipt by Lessor of all
of the amounts provided in this Section 22.1, the obligation of Lessee to pay
Basic Rent hereunder shall cease and the Lease Term shall end.

         If Lessee elects to exercise the purchase option provided for in this
Section 22.1, Lessee shall, as the purchase price therefor, in the sole
discretion of Lessee, either (i) pay the Early Purchase Price, together with all
other amounts due and owing by Lessee under the Operative Agreements, as
specified in the paragraph above or (ii) pay the difference between the amount
specified in clause (i) and the outstanding principal amount of the Equipment
Notes as of the Early Purchase Date and assume on a full recourse basis all of
the Owner Trustee's obligations under the Indenture in respect of the
indebtedness evidenced by such Equipment Notes related to such Units as provided
in Section 3.6 of the Indenture; provided, that, following such assumption, the
purchased Units shall remain subject to the Lien of a separate indenture similar
to the Indenture pursuant to Section 3.6 of the Indenture. Lessee will make the
payments required by foregoing clause (i) or assume the indebtedness evidenced
by the Equipment Notes as provided in foregoing clause (ii) on the Early
Purchase Date in immediately available funds against delivery of a bill of sale
transferring and assigning to Lessee all right, title and interest of Lessor in
and to the Units on an "as-is" "where-is" basis and containing a warranty as to
the absence of Lessor's Liens; provided, however, that Lessee shall have the
option of specifying in such notice under this Section 22.1 its election to
defer payment of a portion of the Early Purchase Price for such Units in four
(4) installments in the amounts and on the dates set forth on Schedule 6 to the
Participation Agreement so long as the portion of the Early Purchase Price
payable by Lessee on the Early Purchase Date in the event of any such election
by Lessee, under any circumstances and in any event, together with other amounts
of Supplemental Rent payable by Lessee on such date, will be at least sufficient
to pay in full, as of the date of payment thereof, the aggregate unpaid
principal and accrued interest of the Equipment Notes together with any Make
Whole Amount, Late Payment Interest and all other amounts owed to the



                                       44
<PAGE>   51



holders of the Equipment Notes under the Operative Agreements; and provided
further, that such deferred portion (i) may be prepaid by Lessee at any time in
whole and (ii) will be secured in favor of Lessor by a letter of credit by a
bank or financial institution acceptable to Owner Participant in its sole
discretion or if acceptable to Owner Participant in its sole discretion a
guaranty of Trinity in form and substance reasonably satisfactory to Lessor. If
Lessee shall fail to fulfill its obligations under this second paragraph of
Section 22.1, all of Lessee's obligations under this Lease and the Operative
Agreements, including, without limitation, Lessee's obligation to pay
installments of Rent, shall continue and Lessee shall be obligated to pay all
costs and expenses, including legal fees and expenses, incurred by Lessor, Owner
Participant and Indenture Trustee as a result of the notice given by Lessee
pursuant to this Section.

         Listed on Schedule 6 to the Participation Agreement as the Basic Rent
Adjustment for the Early Purchase Date is the amount of Basic Rent that, as of
the Early Purchase Date, has been paid for periods after the Early Purchase Date
(based upon the assumption that all prior amounts of Basic Rent due have been
paid) or the amount of Basic Rent that, as of the Early Purchase Date, is the
amount of Basic Rent that has accrued but has not been paid for periods prior to
the Early Purchase Date. If Lessee exercises its Early Purchase Option and the
Basic Rent Adjustment is negative and Lessee pays all other amounts due in
relation to such exercise, then Lessee shall pay an amount equal to the Early
Purchase Price less the absolute value of the amount of such Basic Rent
Adjustment listed on Schedule 6 to the Participation Agreement (as a rebate of
such Basic Rent and not as a reduction in Early Purchase Price). If Lessee
exercises the Early Purchase Option and the Basic Rent Adjustment is positive,
Lessee shall pay an amount equal to the Early Purchase Price plus the Basic Rent
Adjustment (as a payment of accrued, but unpaid Basic Rent and not an increase
in the Early Purchase Price). If Lessee elects to pay the Early Purchase Price
in installments, then the amount of Basic Rent Adjustment listed on Schedule 6
to the Participation Agreement shall increase or decrease, as the case may be,
the amount of Early Purchase Price payable by Lessee on the Early Purchase Date.

         Notwithstanding the foregoing provisions of this Section 22.1 to the
contrary, Lessee may purchase or cause an Affiliate of Lessee to purchase the
Beneficial Interest in lieu of Lessee purchasing the Units pursuant to this
Section 22.1 for a purchase price equal to the Beneficial Interest Purchase
Price and may keep this Lease (and the Equipment Notes) in place; provided, that
Lessee shall remain liable under this Lease to pay Basic Rent and all other
payments hereunder in full, provided, further, that such purchase shall be made
in all respects in accordance with Section 6.9 of the Participation Agreement.

         Section 22.2 Election to Retain or Return Equipment at End of Basic or
Renewal Term. Not less than 180 days and not more than 360 days prior to the end



                                       45
<PAGE>   52



of the Basic Term or any Renewal Term, Lessee shall give Lessor a preliminary
notice of its decision to return or retain the Units and the units subject to
the Other Lease (it being understood that at the end of the Basic Term or any
Renewal Term Lessee must return all (and not less than all) such Units and units
if it returns any, or retain all (and not less than all) such Units and units if
it retains any) at the end of the Basic Term or such Renewal Term and not less
than 120 days prior to the end of the Basic Term or the end of any Renewal Term,
Lessee shall give Lessor irrevocable written notice of its decision to return or
retain the Units at the end of the Basic Term or such Renewal Term. If Lessee
elects to retain Units, Lessee shall comply with Section 22.3 and/or 22.4
hereof, as it may elect in accordance with the provisions thereof including the
notice requirements stated therein. If Lessee fails to give the 120 days' notice
required by this Section 22.2, or a subsequent notice required by Section 22.3
or 22.4, Lessee shall be deemed to have irrevocably elected to return all of the
Units at the end of the Basic Term or the applicable Renewal Term, as the case
may be, in accordance with Section 6.

         Section 22.3 Purchase Option. Provided that Lessee shall have duly
given the notice required by Section 22.2 and by the next succeeding sentence of
this Section 22.3 and, in the case of a purchase, Lessee shall have given a
corresponding notice under the Other Lease and shall upon the purchase of the
Units hereunder concurrently purchase the units under the Other Lease, Lessee
shall have the right and, upon the giving of such notice under this Section
22.3, the obligation to pur-chase all of the Units at a price equal to the Fair
Market Sales Value of such Units, at the expiration of the Basic Term, or, if a
Renewal Term is then in effect, at the end of such Renewal Term, plus all other
amounts due and owing by Lessee under the Operative Agreements, including,
without limitation, Late Payment Interest and any unpaid Rent (so that, after
receipt and application of all such payments, but without withdrawal from any
Reserve Account, Owner Participant shall be entitled under the terms of the
Collateral Agency Agreement to receive, and does receive, taking into account
all Basic Rent payments in respect of the Units, the sum of the Accumulated
Equity Deficiency Amount and Late Payment Interest related thereto and any other
amounts then due to Owner Participant). Lessee shall give Lessor written notice
not less than 90 days and not more than 360 days prior to the end of the Basic
Term or any Renewal Term, as the case may be, of its election to exercise the
purchase option provided for in this Section 22.3, which notice shall be
irrevocable. Payment of the purchase price, together with all other amounts due
and owing by Lessee under the Operative Agreements shall be made at the place of
payment specified in Section 3.5 hereof in immediately available funds against
delivery of a bill of sale transferring and assigning to Lessee all right, title
and interest of Lessor in and to such Units on an "as-is" "where-is" basis and
containing a warranty as to the absence of Lessor's Liens. Lessor shall not be
required to make any other representation or warranty as to the condition of
such Units or any other matters, and may specifically disclaim any such
representations or warranties.

         Section 22.4 Renewal Option. Provided no Event of Default shall have
occurred and be continuing and Lessee shall have duly given the notice required
by Section 22.2, and the corresponding notice under the Other Lease and shall
upon the renewal of the Units hereunder concurrently renew the units under the
Other Lease and Lessee has not exercised its option to purchase the Units
pursuant to Section 22.3, Lessee shall have the right and, upon the giving of a
notice under this Section 22.4 as below provided, the obligation to lease
pursuant to this Lease all (but not less than all) of the Units at the
expiration of the Basic Term or any applicable Renewal Term. Lessee may exercise
this renewal option by giving Lessor written notice not less than 90 days and
not more than 360 days prior to the end of the Basic Term (or, in the
circumstances described below the then Renewal Term) that Lessee elects to renew
this Lease with respect to all, but not less than all, of the Units then leased
hereunder at a rental payment calculated by reference to the then fair market
rental value (a "Fair Market Renewal") or a fixed rental (a "Fixed Rate
Renewal"). At Lessee's option, such renewal may, in the case of a Fair Market
Renewal, be for a renewal term of one or more years or, in the case of a Fixed
Rate Renewal, be for an initial renewal term of three years (but not to extend
beyond the Outside Renewal Date) and in connection with any renewal term
following the initial renewal term, a term of one year or more expiring not
later than the Outside Renewal Date, in each case as Lessee shall specify in
such notice, which notice shall be irrevocable. The Basic Rent for each Unit
during any Renewal Term (the "Renewal Rent") shall (a) in the case of any Fixed
Rate Renewal, be 1/12th of 100% of the average annual Basic Rent allocated over
the period from the end of the Basic Rent Holiday through the Basic Term
Expiration Date, payable monthly in arrears and (b) in the case of any Fair
Market Renewal, be 100% of the Fair Market Rental Value determined as of the
commencement of the applicable Renewal Term; provided, however, that in the case
of the first two years of the Fair Market Renewal period(s) that immediately
follow the Basic Term Expiration Date (whether under Section 22.4 or Section
6.1), be 105% of the Fair Market Rental Value determined as of the commencement
of the applicable Renewal Term; provided further, however, that the preceding
proviso shall not apply in the event that the Lessee provides the Lessor, at the
Lessee's sole cost and expense, with an opinion of independent tax counsel
selected by Lessor (which counsel shall be selected by Lessor from among four
nationally recognized law firms proposed by Lessee, each of which must be
experienced in leveraged leasing transactions similar to the transactions
contemplated herein) to the effect that applicable Treasury Regulations (or
other administrative pronouncements upon which taxpayers may rely for Federal
income tax purposes) will permit rent for such Renewal Term at a rate equal to
100% of the fair market rent determined as of the time of such Renewal Term
without resulting in any adverse Federal income tax consequences to the Owner
Participant Parent (within the meaning of the Tax Indemnity Agreement) under
Code Section 467 or any successor provision thereto. Each Renewal Term shall
commence immediately upon the expiration of the Basic Term or the preceding
Renewal Term, as the case may be. Lessee shall not be entitled to enter any
Fixed Rate Renewal following the expiry of any Fair Market Renewal.

         Section 22.5 Rent Appraisal; Outside Renewal Date. Promptly following
Lessee's irrevocable written notice pursuant to Section 22.2 of its election to
retain the Units at the end of the Basic Term or any Renewal Term (and, in any
event, if it is anticipated that there will be any Extended Units at the end of
the Basic Term or such Renewal Term), Lessor and Lessee shall determine (a) if
Lessee shall have exercised a Fixed Rate Renewal, (i) the remaining useful life
and Fair Market Sales Value (based on the actual condition of a reasonable
sampling of such Units and determined pursuant to the appraisal procedure set
forth in the definition of Fair Market Sales Value) of the Units, and (ii) the
latest date such that (1) the period from the Closing Date to such date would
not exceed 80% of the useful life of any Unit (as determined in subclause (i)
above) from and after the Closing Date, and (2) the Fair Market Sales Value of
each Unit (determined without regard to inflation or deflation from the Closing
Date) on such date would not be less than 20% of the Equipment Cost of such Unit
(such date determined under this subclause (ii) shall thereafter be the latest
date to which this Lease may be renewed pursuant to a Fixed Rate Renewal under
Section 22.4 (the "Outside Renewal Date")), (b) if Lessee shall have exercised
the purchase option under Section 22.3(i) or any renewal option under Section
22.4, the Fair Market Sales Value of the applicable Units as of the end of the
then existing Basic Term or Renewal Term, as applicable, in each case assuming
such Units are at least in the condition required by this Lease, and (c) if
Lessee shall have exercised a Fair Market Renewal (or if it is anticipated that
there will be any Extended Units at the end the Basic Term or such Renewal
Term), the Fair Market Rental Value of the applicable Units as of the end of the
then existing Basic Term or Renewal Term, as applicable, in each case assuming
such Units are at least in the condition required by this Lease.

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

         Section 22.7 Deemed Renewals. If Lessee does not exercise its purchase
option under Section 22.3 or its renewal option under Section 22.4 at the end of
the Basic Term or any Renewal Term, then the Lease for any Unit subject to a
Sublease at the end of the Basic Term or such Renewal Term shall be deemed
automatically renewed for a Renewal Term expiring at the expiration of such



                                       48
<PAGE>   55



Sublease's term (but in no event later than three years following the expiry of
the Basic Term or such Renewal Term, as applicable) (such Unit, an "Extended
Unit"). The terms and conditions of any such deemed renewal of a Unit under this
Section 22.7 including rent shall otherwise be those generally provided in
Section 22.4 in respect of a Fair Market Renewal for the period thereof (which
shall be considered a Renewal Term).

         Section 22.8 Funding of Accounts on Purchase. Lessee will not exercise
the purchase option under this Section 22 unless either (a) the full amount
required to fund the Post Lease Term Reserve Account is (upon consummation of
such purchase and distribution of all amounts required to be distributed by the
Collateral Agent under the Collateral Agency Agreement) and will be then
available to the Collateral Agent to fund such account or (b) an indemnity
pursuant to Section 3.13 of the Collateral Agency Agreement has been provided.

SECTION 23. Limitation of Lessor's Liability.

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

SECTION 24. Investment of Security Funds.

         Any moneys received by Lessor or the Indenture Trustee pursuant to
Section 12.2 which are required to be paid to Lessee after completion of repairs
to be made pursuant to Section 12.2 or pursuant to Section 11.4(a) or 11.5, as
the case may be, shall be paid directly to the appropriate Non-Shared Payments
Account established under the Collateral Agency Agreement.

SECTION 25. Miscellaneous.

         Section 25.1 Governing Law; Severability. THIS LEASE SHALL BE GOVERNED
BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF
NEW YORK, WITHOUT REGARD TO CONFLICTS OF LAW PRINCIPLES (OTHER THAN SECTION
5-1401 OF THE NEW YORK GENERAL OBLIGATIONS LAW). Whenever possible, each
provision



                                       49
<PAGE>   56



of this Lease shall be interpreted in such manner as to be effective and valid
under applicable law, but if any provision of this Lease shall be prohibited by
or invalid under the laws of any jurisdiction, such provision, as to such
jurisdiction, shall be ineffective to the extent of such prohibition or
invalidity, without invalidating the remainder of such provision or the
remaining provisions of this Lease in any other jurisdiction.

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

         Section 25.3 Headings and Table of Contents; Section References. The
headings of the sections of this Lease and the Table of Contents are inserted
for purposes of convenience only and shall not be construed to affect the
meaning or construction of any of the provisions hereof. All references herein
to numbered sections, unless otherwise indicated, are to sections of this Lease.

         Section 25.4 Successors and Assigns. This Lease shall be binding upon
and shall inure to the benefit of, and shall be enforceable by, the parties
hereto and their respective permitted successors and permitted assigns.

         Section 25.5 True Lease. It is the intent of the parties to this Lease
that it will be a true lease and not a "conditional sale", that Lessor shall at
all times be considered to be the owner of each Unit which is the subject of
this Lease for the purposes of all federal, state, city and local income taxes,
that this Lease conveys to Lessee no right, title or interest in any Unit except
as lessee and that the Lease will be a finance lease under the provisions of
Article 2A of the New York Uniform Commercial Code. Nothing contained in this
Section 25.5 shall be construed to limit Lessee's use or operation of any Unit
or constitute a representation, warranty or covenant by Lessee as to tax
consequences.

         The parties hereto hereby agree that Lessee's obligation to make
payments of the type described in the definition of "Excepted Property" is a
separate and independent obligation from its obligation to make other Rent
payments, and that Lessee's obligation to make payments of the type described in
the definition of "Excepted Property" may be independently enforced and may be
assigned, pledged or otherwise transferred separately from Lessee's obligations
to make other Rent payments. The obligation to make such payments has been
included herein for the convenience of the parties.

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

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

         Section 25.8 Business Days. If any payment is to be made hereunder or
any action is to be taken hereunder on any date that is not a Business Day, such
payment or action otherwise required to be made or taken on such date shall be
made or taken on the immediately succeeding Business Day with the same force and
effect as if made or taken on such scheduled date and as to any payment
(provided any such payment is made on such succeeding Business Day) no interest
shall accrue on the amount of such payment from and after such scheduled date to
the time of such payment on such next succeeding Business Day.

         Section 25.9 Directly or Indirectly; Performance by Managers. Where any
provision in this Lease refers to action to be taken by any Person, or which
such Person is prohibited from taking, such provision shall be applicable
whether such action is taken directly or indirectly by such Person. In this
regard, it is understood and agreed that Lessee has entered into the Management
Agreement with the Manager and the Insurance Agreement with the Insurance
Manager, under which agreements certain rights and obligations of Lessee
hereunder will be exercised and performed by such Persons on behalf of Lessee.
Lessee agrees to instruct the Manager and the Insurance Manager to take such
actions as shall be necessary or appropriate under such agreements so that
Lessee shall be in compliance in all material respects with its obligations
hereunder and under the other Operative Agreements.

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