                            EQUIPMENT LEASE AGREEMENT
                                 (TRLIV 2004-1A)

            This Equipment Lease Agreement (TRLIV 2004-1A), dated as of August
19, 2004 (this "Lease"), is by and between TRLIV 2004-1A Railcar Statutory
Trust, a Connecticut statutory trust, as Lessor, and Trinity Rail Leasing IV
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 date immediately prior to the Basic Term
Expiration Date. Subject and pursuant to Section 22.4, Lessee may elect one
Renewal Term.

         Section 3.2 Basic Rent. Lessee hereby agrees to pay to 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 each Unit subject to lease hereunder 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). Notwithstanding Lessee's payment
obligations set forth in the preceding two sentences, Lessee's liability on
account of the use of the Units during each Lease Period shall accrue and be
allocated within the meaning of Treasury Regulation Section
1.467-1(c)(2)(ii)(A)(2) to each Lease Period as set forth on Schedule 3-B to the
Participation

<PAGE>

Agreement. Basic Rent shall be allocated to each calendar year in the Basic Term
based upon the assumption that each calendar year in the Basic Term is 360 days,
consisting of four 90-day quarters and twelve 30-day months. It is the intention
of Lessor and Lessee that (x) 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 Treasury Regulation Section 1.467-1(c)(2)(ii)
and (y) the first three Lease Periods shall constitute a rent holiday to which
no Basic Rent is allocated. 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 have been 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.

         It is the intention of the parties hereto that Basic Rent shall
constitute "fixed rent" within the meaning of Treasury Regulation Section
1.467-1(h)(3) and that Basic Rent paid shall always equal Basic Rent allocated.
In the event that (i) the amount of fixed rent payable under the Lease is deemed
to be less than or more than the aggregate amount of Basic Rent identified on
Schedule 3-A to the Participation Agreement and (ii) such increase is deemed to
be an increase of fixed rent (within the meaning of Treasury Regulation Section
1.467-1(h)(3)) or such decrease is deemed to be a decrease of fixed rent (within
the meaning of Treasury Regulation Section 1.467-1(h)(3)), then the amount of
Basic Rent allocated on Schedule 3-B to the Participation Agreement for each
Lease Period shall be increased or decreased, as the case may be, by an amount
equal to the deemed increase or decrease in Basic Rent payments multiplied by a
fraction, the numerator of which is equal to the amount of Basic Rent allocated
for such Lease Period on Schedule 3-B to the Participation Agreement and the
denominator of which is the aggregate amount of the Basic Rent allocated for all
Lease Periods on Schedule 3-B to the Participation Agreement. The adjusted Basic
Rent allocated shall constitute Basic Rent allocated for all purposes of this
Lease.

         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, an amount equal to
the sum of (x) 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 and (y) the Policy Provider Base
Premium Amount required to be paid on the due date of such installment.

         Section 3.3 Supplemental Rent. Lessee also agrees to pay to Lessor, or
to whosoever shall be entitled thereto, any and all Supplemental Rent, as and
when due, 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
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

                                       2
<PAGE>

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 6.9
(other than clause 6.9(a)(C) thereof) of the Participation Agreement, and in the
case of any refinancing of the Equipment Notes pursuant to Section 10.2 of the
Participation Agreement but excluding any Make-Whole Amount payable pursuant to
Section 4.4(b) of the Indenture. 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
payments and allocations of 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,
23rd Floor, Hartford, CT 06103, Attention: Corporate Trust Department, 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 Rodney
Square North, 1100 N. Market Street, Wilmington, DE 19890-0001, ABA No.
031100092, Account No. 067435-000, Ref: Trinity Rail-TRLIV 2004-1A, 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 by any Person pursuant to distribution from any
of the Accounts 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 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 for all purposes
(including for all tax purposes) 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 on or prior to the date on which a Lease Supplement is executed and
delivered in respect of a Replacement

                                       3
<PAGE>

Unit pursuant to Section 11.4(b) (or, if the applicable Replacement Unit is not
in the possession of Lessee or the Manager, as soon as practicable and in any
event no later than ten Business Days after the earliest date on which Lessee or
the Manager obtains possession of such Replacement Unit (whether for purposes of
repair or maintenance or otherwise)), Lessee will cause, each Unit to be
numbered with the 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, as soon as practicable (and in any event 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, but in any event within 30 days, 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 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
provided in Section 4.2 above, Lessee will not allow or permit the name of any
Person to be placed on any Unit as a designation that might reasonably be
interpreted as a claim of ownership and shall not, and shall not permit the
Manager, any Sublessee or any other Person to, alter the reporting marks with
respect to any Unit. Lessee may cause or permit any Unit to be lettered with the
names or initials or other insignia (other than reporting marks) customarily
used by Lessee or any applicable Permitted Sublessee or any of their respective
Affiliates on railcars 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 such
Permitted 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

                                       4
<PAGE>

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,
(iv) EACH UNIT IS LEASED HEREUNDER SUBJECT TO ALL APPLICABLE LAWS AND
GOVERNMENTAL REGULATIONS NOW IN EFFECT OR HEREAFTER ADOPTED AND (v) LESSOR
LEASES AND LESSEE TAKES EACH UNIT "AS-IS", "WHERE-IS" AND "WITH ALL FAULTS", IN
WHATEVER CONDITION IT MAY BE, AND LESSEE ACKNOWLEDGES THAT NONE OF LESSOR, AS
LESSOR OR IN ITS INDIVIDUAL CAPACITY, INDENTURE TRUSTEE, ANY LOAN PARTICIPANT,
THE POLICY PROVIDER OR THE OWNER PARTICIPANT MAKES NOR SHALL BE DEEMED TO HAVE
MADE, AND EACH EXPRESSLY DISCLAIMS, ANY AND ALL RIGHTS, CLAIMS, WARRANTIES OR
REPRESENTATIONS EITHER EXPRESS OR IMPLIED, AS TO THE VALUE, USE, CONDITION,
FITNESS FOR ANY PARTICULAR PURPOSE, DESIGN, OPERATION, MERCHANTABILITY THEREOF
OR AS TO THE TITLE OF ANY UNIT, THE QUALITY OF THE MATERIAL OR WORKMANSHIP
THEREOF OR CONFORMITY THEREOF TO SPECIFICATIONS, FREEDOM FROM PATENT, COPYRIGHT
OR TRADEMARK INFRINGEMENT, THE ABSENCE OF ANY LATENT OR OTHER DEFECT, WHETHER OR
NOT DISCOVERABLE, OR AS TO THE ABSENCE OF ANY OBLIGATIONS BASED ON STRICT
LIABILITY IN TORT OR ANY OTHER EXPRESS OR IMPLIED REPRESENTATION OR WARRANTY
WHATSOEVER WITH RESPECT THERETO AND EACH OF LESSOR, INDENTURE TRUSTEE, ANY LOAN
PARTICIPANT, THE POLICY PROVIDER 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. 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 and Obligations Under 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 in each case, subject to
the applicable provisions of this Lease and the Collateral Agency Agreement, if
any. Lessor hereby delegates to Lessee, and Lessee hereby assumes and shall be
obligated to perform, all obligations of Lessor under each Sublease, in each
case subject to the applicable provisions of this Lease and Collateral Agency
Agreement, if any.

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 the 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

                                       5
<PAGE>

locations ("Storage Locations") used by Lessee for the storage of rolling stock
within the Contiguous United States with sufficient available storage capacity
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(s), f.o.b. such location(s), (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 120 days after the later of (i) the date of such expiration and (ii) the
date on which such Unit is in compliance with the conditions set forth in
Section 6.2. On or before the 120th 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.

                                       6
<PAGE>

         (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.

         (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 instead 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 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 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
accordance with Section 6.1(c) and (iii) compliance by such Unit with Section
6.2, this Lease and the obligation to pay Basic Rent for such Unit accruing
subsequent to the expiration of the Lease Term with respect to such Unit shall
terminate.

         (e) 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, as
liquidated damages and not as a penalty, an amount equal to the daily equivalent
of the average Basic Rent for the Basic Term or the Renewal Term, as applicable,
to such Unit. 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

                                       7
<PAGE>

terminate this Lease under Section 15 as a result of such failure or to have
such Unit returned to it for possession or storage.

         (f) The assembling, delivery, storage and transporting of the Units as
hereinbefore provided are of the essence of this Lease, and, upon application to
any court of equity having jurisdiction on the premises, the Lessor shall be
entitled to a decree against the Lessee requiring specific performance thereof.
All rent earned in respect of the Units after the date of termination of this
Lease shall belong to the Lessor and, if received by the Lessee, shall be
promptly turned over to the Lessor.

         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 then in effect, (vi)
empty, (vii) cleaned in accordance with Prudent Industry Practice, including
with respect to Hazardous Substances 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 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 provided further that if as a
result of such inspection any Unit is found to be not in compliance with this
Section 6.2, the Lessee will (i) promptly take such steps as are necessary to
bring such Unit in compliance with the conditions set forth in this Section 6.2
and (ii) pay the reasonable cost and expense of 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 for purposes of this Lease unless and
until it is in compliance with the conditions set forth in this Section 6.2.

SECTION 7. Liens.

         Lessee will not directly or indirectly create, incur, assume, permit or
suffer to exist any Lien, including without limitation any Lease or Sublease, 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 maybe

                                       8
<PAGE>

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, and 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 in respect of railcars
owned, leased or managed by the Manager similar in type to such Unit or, with
respect to (A) any Equipment subject to an Existing Equipment Sublease that is a
Net Sublease, maintenance practices used by the applicable Sublessee in respect
of railcars similar in type to such Unit used by such Sublessee on its domestic
routes in the United States; (provided further, however that after the return to
the Manager of any Unit which was subject to a Net Sublease immediately prior to
such return, such Unit shall be maintained and repaired in all material respects
in a manner consistent with maintenance practices used by the Manager in respect
of railcars owned, leased or managed by the Manager similar in type to such
Unit) and (B) any Permitted Sublease that is a Net Sublease entered into after
the Closing Date where (x) the long term senior unsecured debt of the applicable
Sublessee is rated at least BBB- by S&P and Baa3 by Moody's (or at least BBB- by
S&P or Baa3 by Moody's if then rated by only one such rating agency) or
similarly rated by any rating agency, (y) the applicable Sublessee is organized
under the laws of the United States or any State thereof and (z) the applicable
Sublessee is the owner or lessee of at least 250 railcars used primarily on
domestic routes in the United States, maintenance practices used by such
Sublessee in respect of railcars similar in type to such Unit, (iii) in
accordance with all manufacturer's warranties in effect but only to the extent
that the lack of compliance therewith would reasonably be expected to adversely
affect the coverage thereunder 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 which is a Net 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 which is a
Net Sublease, the applicable Sublessee, as applicable, Lessee (or such
Sublessee) may, in good faith and by appropriate proceedings diligently
conducted, contest the validity or application of any such standard, rule or
regulation in any manner that does not (w) materially interfere with the use,
possession, operation or return of any of the Units, (x) materially adversely
affect the rights or interests of Lessor, Policy Provider or the Indenture
Trustee in the Units or hereunder, (y) expose Lessor, Policy Provider or the
Indenture Trustee to criminal sanctions or (z) violate any maintenance
requirements contained in any insurance policy required to be maintained by the
Lessee under this Lease or the Collateral Agency Agreement if such violation
would reasonably be expected to adversely affect the coverage thereunder;
provided further, that Lessee shall promptly notify

                                       9
<PAGE>

Lessor, Policy Provider and Indenture Trustee in reasonable detail of any such
contest. In no event shall 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 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(a)(i),
11.3 and 11.4.

         (c) 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, and Lessee agrees that it shall and shall cause the
Manager to, assert and enforce all such claims and rights; 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.

         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 seventeen and one half percent (17.5%) of the Units (as
determined by mileage records and measured annually on a calendar year basis) be
used outside the Contiguous United States; provided, that such maximum
percentage shall be increased to (i) 25% on the sixth anniversary of the date
hereof and (ii) 40% on the ninth anniversary of the date hereof. In addition, in
no event shall more than 30% of the Units, the Other Units and the Pledged Units
in the aggregate (as determined by mileage records and measured at the end of
each calendar quarter for the 12 month period ending on the last day of the
calendar quarter immediately preceding such calendar quarter) be used in Mexico.
Nothing in this Section 8.2 shall be deemed to constitute permission by Lessor
to any Person that

                                       10
<PAGE>

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 Permitted Subleases.

         A "Permitted Sublease" means each (a) Existing Equipment Sublease
(including any renewal or extension thereof to the extent such renewal or
extension complies with clauses (i), (iii), (iv), (v), (vi) and (vii) below) and
(b) a sublease, car contract or other agreement granting permission for the use
of a Unit, which sublease, car contract or other agreement meets all of the
following requirements:

         (i) the sublessee or user thereunder is a Permitted Sublessee and,
after giving effect to the entering into of such agreement, the number of Units,
Pledged Units and Other Units leased or subleased to such sublessee or user and
all of its Affiliates, in the aggregate, does not exceed 10% (or 12.2% with
respect to Commercial Metals Company) of the sum of the aggregate number of
Units then subject to this Lease, the aggregate number of Other Units subject to
the Other Leases and the aggregate number of Pledged Units then subject to the
Lien of the Collateral Agency Agreement; provided, that for purposes of this
clause (i), "sublessee" shall mean each Person leasing such Units from the
Lessee as well as each Person subleasing such Units from any other sublessee or
other Person;

         (ii) if such agreement permits the sublessee or user thereunder to
further sublease any of the Units subject to such agreement, then such agreement
shall require that any such further sublease be conditioned on (A) the sublessee
obtaining Lessee's (as sublessor) prior consent to such further sublease, (B)
the sublessee agreeing that any such further sublease will have provisions
making it terminable (as to the sub-sublessee) at the request of the Lessor or
Lessee, as applicable, and prohibiting any further subleasing by the
sub-sublessee and will not contain any purchase option in favor of the
sub-sublessee, (C) such agreement providing that no such further sublease shall
relieve the sublessee or user under the sublease from liability thereunder and
(D) the applicable sub-sublessee satisfying the requirements for a "Permitted
Sublessee" set forth below;

         (iii) such agreement was on an arm's length basis with fair market
terms on the date of its execution, and does not require any prepayment of
rental payments throughout the term of such agreement;

         (iv) such agreement does not contain any purchase option in favor of
the sublessee or user thereunder;

         (v) such agreement (or any related consent, acknowledgment of
assignment, side letter or similar written instrument executed by such
sublessee) permits the assignment, pledge, mortgage or other similar disposition
of the lease of the related railcar without notice to or consent by the
sublessee (or, in the case of a written instrument described in the foregoing
parenthetical, any further notice to or consent by the sublessee), it being
understood that the inclusion within such permission or written instrument of
language to the effect that such sublessee consent is conditioned on the
assignees' agreement that it takes its interest in the railcar

                                       11
<PAGE>

and/or related sublease subject to the rights of the sublessee in such railcar
under the sublease, shall not in and of itself be deemed to constitute the
sublease as other than a Permitted Sublease;

         (vi) such agreement contains a legend in bold-faced capitalized print
stating that "This sublease and the railcars subleased hereunder have been
assigned to TRLIV 2004-1A Railcar Statutory Trust by Trinity Rail Leasing Trust
II pursuant to an Assignment and Assumption and a Bill of Sale each dated as of
August 19, 2004 and TRLIV 2004-1A Railcar Trust has further assigned this
sublease and such railcars to Wilmington Trust Company, as secured party, in its
capacity as Indenture Trustee under the Trust Indenture and Security Agreement
dated as of August 19, 2004 between TRLIV 2004-1A Railcar Statutory Trust and
Wilmington Trust Company, as Indenture Trustee";

         (vii) such agreement does not extend more than two years beyond the end
of the Basic Term (without the prior written consent of the Owner Participant);
and

         (viii) such agreement contains a provision substantially similar to
Article 6 in the Form of Net Sublease attached as Exhibit B-1 hereto or Article
4 in the Form of Full Service Sublease attached as Exhibit B-2 hereto; provided
that this clause (viii) shall not apply if such agreement is subject to the
terms of, or entered into pursuant to, an existing master lease agreement dated
on or prior to the Closing Date which does not contain such a provision.

         As used herein, a "Permitted Sublessee" means any of the following:

         (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;
    provided, however, that the credit profile of sublessees of the Units shall
    not vary materially from the credit profile of sublessees of other railcars
    owned, leased or managed by the Manager; or

         (iii) wholly-owned Subsidiaries of Trinity organized under the laws of
    (x) Canada or any political subdivision thereof or (y) Mexico or any
    political subdivision thereof, in each case so long as such subleases are on
    an arm's length basis;

provided, however, that a Person organized under the laws of Mexico or any state
thereof (a "Mexican Sublessee") shall not constitute a Permitted Sublessee
unless after giving effect to the contemplated sublease to such Mexican
Sublessee, 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 (or sub-subleased by a sublessee organized under the
laws of the United States of America or any state thereof or the District of
Columbia, Canada or any

                                       12
<PAGE>

province thereof to a sub-sublessee organized under the laws of Mexico or any
state thereof, as applicable) to all Mexican Sublessees does not exceed 15% of
the sum of the Units, the Other Units and the Pledged Units in the aggregate,
provided further, that at no time shall more than 10% of the Units, the Other
Units and the Pledged Units, in the aggregate be subleased (or sub-subleased by
a sublessee organized under the laws of the United States of America or any
state thereof or the District of Columbia, Canada or any province thereof to a
sub-sublessee organized under the laws of Mexico or any state thereof, as
applicable) to Mexican Sublessees, the long term senior unsecured debt of which
is unrated or rated below BBB- or Baa3, as determined by S&P and Moody's, as
applicable.

         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 Partnership's jurisdiction of formation
and/or other similar filings with the STB, the Registrar General of Canada and
any applicable Canadian provinces covering all Subleases generally and delivery
of the original copies of the applicable Subleases in the manner set forth in
the Collateral Agency Agreement.

         Lessee will use commercially reasonable efforts to have each Sublease
other than Existing Equipment Subleases be substantially in the form attached as
Exhibit B-1 or Exhibit B-2 and contain provisions relating to the requirement
that such Sublease be subject and subordinate to the rights of assignees and/or
security interest grantees in respect thereof. Promptly after the execution of
each Sublease, Lessee shall deliver the original, fully executed counterpart
number one of each such Sublease to the Collateral Agent in accordance with the
provisions of the Collateral Agency Agreement or, if the circumstance described
in Section 2.5(d) of the Collateral Agency Agreement shall have occurred, to the
custodian described in such Section 2.5(d).

         No sublease entered into by Lessee hereunder shall relieve Lessee of
any liability or obligation hereunder, which shall be and remain those of a
principal and not a surety. Nothing in this Section 8.3 shall be deemed to
constitute permission to any Person in possession of any Unit pursuant to any
such sublease to take any action inconsistent with the terms and provisions of
this Lease or any of the other Operative Agreements. 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 or cause to be made
such Required Modification at its own expense; provided, however, that Lessee
(or applicable Sublessee) 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 manner that does not materially interfere
with the use, possession, subleasing, operation, maintenance or return of any
Unit or materially adversely affect the rights or interests of Lessor or the
Indenture Trustee in the Units or Subleases or expose Lessor, Policy Provider or
the Indenture Trustee to criminal sanctions. Title to any Required Modification
shall immediately vest in Lessor. Notwithstanding anything herein to the
contrary, if Lessee determines in its reasonable judgment consistent with
Prudent Industry

                                       13
<PAGE>

Practice (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, 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; provided, however, that Lessee
shall not discriminate against such Unit in making such determination of
economic impracticability as compared with other equipment of the same type and
similarly situated that is owned or leased by Lessee or managed by Manager.

         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 expense, modify, alter or improve any Unit in a manner which is not required
by Section 9.1 (a "Modification"); provided that no Modification (i) shall
diminish the fair market value, residual value, utility or remaining economic
useful life of such Unit below the fair market value, residual value, utility 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 or (ii) cause
such Unit to become "limited use property" within the meaning of Revenue
Procedure 2001-28 or Revenue Procedure 2001-29. 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; provided that such
removal shall not (i) diminish the fair market value, residual value, utility or
remaining economic useful life of the Unit to which such Severable Modifications
relate below the fair market value, residual value, utility or remaining
economic useful life thereof immediately prior to the addition of such Severable
Modifications, 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 or
(ii) cause such Unit to become "limited use property" within the meaning of
Revenue Procedure 2001-28 or Revenue Procedure 2001-29. 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

                                       14
<PAGE>

Liens (other than Permitted Liens) and in as good operating condition as, and
with a fair market value, residual value, utility 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; provided that Lessee may not remove any item if such removal would
cause such Unit to become "limited use property" within the meaning of Revenue
Procedure 2001-28 or Revenue Procedure 2001-29. 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
option at any time or from time to time during the Basic Term on or after
February 14, 2012 to terminate the Lease with respect to any or all of the Units
(provided that, Lessee shall exercise such termination hereunder and under the
comparable provisions contained in the Other Leases (i) with respect to at least
100 railcars and, (ii) 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) (such Units, 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 (i) 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
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
(ii) a Rating Agency Confirmation and (z) Lessee delivers at least 120 days'
prior notice to Lessor and the Indenture Trustee 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. 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 with respect to the
Terminated Units; 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 agrees that
whether or not it withdraws a termination notice it will reimburse Lessor, the
Policy Provider and the

                                       15
<PAGE>

Indenture Trustee 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, the Manager or any of their respective
Affiliates 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 Manager or an Affiliate of Lessee or Manager (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)) that 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 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 with respect to the Terminated Units 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 applicable sales, transfer or similar taxes) of the
Terminated Units, (C) an amount equal to any unpaid Late Payment Interest in
respect of any Rent in respect of the Terminated Units not paid when due
(including, for the avoidance of doubt, Rent corresponding to 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 in respect of the Terminated Units
(exclusive of any Basic Rent on the Terminated Units due on such date) then due
and payable hereunder (which shall include, without limitation, a portion of the
Policy Provider Amounts and Policy Provider Reimbursement Costs, if any, equal
to the product obtained by multiplying the unpaid Policy Provider Amounts and
Policy Provider Reimbursement Costs 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), so
that, after receipt and application of all such payments, but without withdrawal
from any CAA Accounts other than the applicable Non-Shared Payments Account, (i)
Lessor 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 portion of the Accumulated Equity
Deficiency Amount allocable to the Terminated Units and Late Payment Interest
related thereto and any other amounts then due to Lessor and (ii) the Policy
Provider has received the portion of Policy Provider Amounts and Policy Provider
Reimbursement Costs calculated above. If no sale shall

                                       16
<PAGE>

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, Policy
Provider and the Indenture Trustee for all reasonable costs and expenses
(including reasonable legal fees and expenses) incurred by any thereof in
connection therewith. 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. 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, (with a copy to the Policy Provider) 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 due and owing on the Termination Date and unpaid (exclusive of any
Basic Rent due on such date in respect of the Terminated Units), any unpaid Late
Payment Interest in respect of any Rent in respect of the Terminated Units not
paid when due (including, for the avoidance of doubt, Rent corresponding to the
principal amount of the Equipment Notes to be prepaid in accordance with Section
2.10(a) of the Indenture), and all other Rent in respect of the Terminated Units
(exclusive of any Basic Rent on the Terminated Units due on such date) then due
and payable hereunder (including, without limitation, a portion of the Policy
Provider Amounts and Policy Provider Reimbursement Costs, if any equal to the
product obtained by multiplying the unpaid Policy Provider Amounts and Policy
Provider Reimbursement Costs by a fraction, the numerator of which shall be the
Equipment Costs of the Terminated Units and the denominator of which shall be
the aggregate Equipment Costs of all Units then subject to this Lease), so that,
after receipt and application of all such payments, but without withdrawal from
any CAA Accounts other than the applicable Non-Shared Payments Account, Lessor
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 portion of the Accumulated Equity Deficiency
Amount allocable to the Terminated Units and Late Payment Interest related
thereto and any other amounts then due to Lessor and the Policy Provider has
received the portion of the Policy Provider Amounts and Policy Provider
Reimbursement Costs calculated above. 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. Also on such date, 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 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; provided,
that if the Lessor or Owner Participant is the Lessee or an Affiliate of the
Lessee, Lessee shall pay to Lessor such additional amounts as are necessary to
pay in full all then unpaid Policy Provider Amounts and,

                                       17
<PAGE>

without duplication, all then unpaid Policy Provider Reimbursement Costs, in
each case, as defined in this Lease and as defined in the Other Lease described
in clause (i) of the definition thereof. Unless all amounts described above in
this Section 10.2 shall have been paid to the Persons entitled thereto on the
Termination Date, this Lease shall continue in full force and effect with
respect to the Terminated Units. Lessor agrees that in the event that Lessor
elects to retain (and does retain) the Terminated Units as provided in this
Section 10.3, for a period of one year after payment by Lessor of all amounts
due and owing by Lessor under this Section 10.3, Lessor may not sell or lease
any of such Terminated Units to Lessee or any of its Affiliates. 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 11. Loss, Destruction Requisition, Etc.

         Section 11.1 Event of Loss. In the event that any Unit (i) shall suffer
damage or contamination which, in Lessee's reasonable judgment (as evidenced by
an 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 have title thereto
taken or appropriated by any governmental authority, agency or instrumentality
under the power of eminent domain or otherwise, or (iv) 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 shorter of (A) 180 days
and (B) the remaining Basic Term or any Renewal Term then in effect (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; Substitution.
(a) Upon the occurrence of an Event of Loss or the deemed occurrence of an Event
of Loss pursuant

                                       18
<PAGE>

to Section 9.1, an election to replace pursuant to Section 8.1(b) or an election
to substitute pursuant to Section 11.2(b), in each case with respect to any Unit
(an "Affected Unit"), Lessee shall within 60 days (or promptly in the case of an
Event of Loss described in clause (iv) of Section 11.1) after a Responsible
Officer of the Manager shall have actual knowledge of the occurrence of such
Event of Loss or election to replace or substitute as provided in Section
11.2(b) give Lessor and the Indenture Trustee notice thereof (which initial
notice shall identify the Unit involved). Thereafter, within the 60-day (or
30-day period in the case of an Event of Loss described in clause (iv) of
Section 11.1) 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) or an election to substitute
pursuant to Section 11.2(b) (in which case Lessee will comply with the
provisions of Section 8.1(b) or 11.2(b) as applicable), if Lessee shall fail to
give such second notice within such period, Lessee shall be deemed to have
elected to perform the option set forth in Section 11.2(a)(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
(or 30th day in the case of an Event of Loss described in clause (iv) of Section
11.1) following such second notice (or Section 8.1(b) or 11.2(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") for each such
Affected Unit, with such 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 (except to a de minimis extent), residual value, utility, remaining
economic useful life and condition at least equal to the Unit so replaced
(assuming such Unit to be replaced was in the condition required to be
maintained by the terms of this Lease) and to be (as of the date of conveyance)
then subject to a currently effective Permitted Sublease and not to be "limited
use property" within the meaning of Revenue Procedure 2001-28 or Revenue
Procedure 2001-29; provided, however, 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; 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 due and owing on such date and
unpaid in respect of such Unit or Units (exclusive of any Basic Rent due on such
date in respect of such Unit or Units), (c) any unpaid Late Payment Interest in
respect of any Rent with respect to such Unit or Units not paid when due
(including, for the avoidance of doubt, Rent corresponding to 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 in respect of such Unit or Units

                                       19
<PAGE>

(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, a portion of the Policy Provider Amounts and Policy Provider
Reimbursement Costs, if any, equal to the product obtained by multiplying the
unpaid Policy Provider Amounts and Policy Provider Reimbursement Costs 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 (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 (or the Special Reserves Account or Transition Expense Account, as such
terms are defined in the Collateral Agency Agreement), Lessor 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 portion of the Accumulated Equity Deficiency Amount allocable to such
Unit or Units and Late Payment Interest related thereto and any other amounts
then due to Lessor and the Policy Provider has received the portion of Policy
Provider Amounts and Policy Provider Reimbursement Costs calculated above, it
being understood that until such Stipulated 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.

         (b) (i) In the event that at any time during the term of this Lease, a
Sublessee shall notify the Lessee that it intends to exercise its purchase
option with respect to any Units ("Sublessee Purchased Units"), the Lessee shall
either (I) pay the greater of (x) the proceeds received from the Sublessee in
respect of the purchase of such Units as increased or decreased by any Basic
Rent Adjustment and (y) the applicable Termination Amount (such greater amount,
the "Sublessee Purchased Units Price") plus all other amounts payable in respect
of such Units in accordance with the provisions of clause (ii) of this Section
11.2(b) or (II) substitute a Replacement Unit for each such Sublessee Purchased
Unit in accordance with and subject to the provisions of Sections 11.2(a)(i),
11.3 and 11.4, with such payment or substitution to be made not later than the
date on which the Sublessee Purchased Units are to be conveyed to the applicable
Sublessee.

         (ii) If Lessee elects to pay the Sublessee Purchased Unit Price as
provided in Section 11.2(b)(i)(I), then Lessee shall pay, or cause to be paid,
to the Lessor an amount equal to the Sublessee Purchased Unit Price with respect
to each Sublessee Purchased Unit, which amount shall be paid without withdrawal
from any CAA Account other than the applicable Non-Shared Payments Account.
Concurrently with the payment by Lessee of the foregoing, Lessee shall also pay
to Lessor (1) any unpaid Late Payment Interest in respect of the Sublessee
Purchased Units (including in respect of the principal amount of the Equipment
Notes to be prepaid), together with all Basic Rent then due and payable with
respect to such Units (excluding any Basic Rent due on the date of the payment
of such Sublessee Purchased Unit Price as set forth above) and (2) a portion of
the Policy Provider Amounts and Policy Provider Reimbursement Costs, if any,
equal to the product obtained by multiplying the unpaid Policy Provider Amounts
and Policy Provider Reimbursement Costs 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;
provided, that if the Lessor or Owner Participant is the Lessee or an Affiliate
of the Lessee, Lessee shall pay to Lessor such additional amounts as are
necessary to pay in full all then unpaid Policy Provider

                                       20
<PAGE>

Amounts and, without duplication, all then unpaid Policy Provider Reimbursement
Costs, in each case, as defined in this Lease and as defined in the Other Lease
described in clause (i) of the definition thereof.

         (c) The Lessor and the Lessee hereby agree to cooperate in good faith,
and to take such actions as each shall reasonably request, to permit each to
treat the substitution of a Replacement Unit for a Sublessee Purchased Unit as
part of a tax deferred exchange under section 1031 of the Code (an "Exchange
Transaction") including allowing the Exchange Transaction to occur after the
Sublessee's notification of its intention to exercise its purchase option but
prior to the Sublessee's exercise of its purchase option.

         Section 11.3 Rent Termination. Upon the replacement or substitution of
any Unit or Units in compliance with Sections 11.2(a)(i) or 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, Lessor shall (subject to
any insurer's right of subrogation, if any) be entitled to any amounts in excess
of Stipulated Loss Amount 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.

         (b) At the time of or prior to any replacement or substitution 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

                                       21
<PAGE>

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 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 (y) describing all
filings and recordings and other actions required pursuant to Section 16 with
respect to the Replacement Units, (E) furnish (I) 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 and (II) to Lessor an opinion from independent tax counsel
selected by Owner Participant to the effect that Owner Participant will not have
any material adverse tax consequences as a result of such replacement or
substitution, (F) furnish Lessor with an engineer's certificate (which may be
from an employee of the Manager) certifying as to the utility, condition and
remaining useful life required under clause (i) of Section 11.2(a), (G) furnish
to Lessor and the Indenture Trustee an Officer's Certificate certifying that the
Replacement Unit has a fair market value (except to a de minimis extent),
residual value, utility 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 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 (I) furnish such other documents and evidence as any
Participant, the Policy Provider, 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. In addition,
as soon as practicable after any such replacement or substitution, cause each
applicable Unit to be numbered with the reporting mark shown on the applicable
Lease Supplement in accordance with Section 4.2 hereof. 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, the
Policy Provider and the Indenture Trustee of the documents and instruments
referred to in the foregoing clauses (A) through (I), 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
leased hereunder and the Replacement Unit shall be deemed a "Unit" as defined
herein. Upon such passage of title, Lessor will transfer to Lessee, "as is" and
"where is" and without recourse or warranty (except as to Lessor's Liens), all
Lessor's right, title and interest in and to the replaced Unit, and upon such
transfer, Lessor will request in writing that the Indenture Trustee execute and
deliver to Lessee an appropriate instrument releasing such replaced Unit from
the lien of the Indenture. Lessee shall pay all reasonable out-of-pocket costs
and expenses (including reasonable legal fees and expenses) incurred by Lessor,
Policy Provider 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

                                       22
<PAGE>

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 that 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-/7 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 beneficial to the insured
thereunder 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 Practice. 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 (or
$100,000, in the event that (i) coverage providing for a $50,000 deductible
amount is not then available on commercially reasonable terms or (ii) a
deductible amount of $100,000 is then customary in the railcar leasing industry
with respect to such coverage and in each case the Lessor shall have received
evidence reasonably satisfactory to it of the foregoing (which may include a
report from an independent insurance advisor chosen by Lessor and reasonably
satisfactory to Lessee); and

         (b) maintain public liability insurance naming Owner Participant,
Lessor, the Trust Company, the Indenture Trustee, the Policy Provider 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 then current deductible amounts maintained by the three largest
companies

                                       23
<PAGE>

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 Equipment 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 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, the Policy Provider 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 no Significant
Default shall have occurred and be continuing the proceeds up to $100,000 for
any loss or damage to any Unit shall be paid to Lessee for the purpose of
repairing or restoring such Unit that has been damaged, (ii) the proceeds in
excess of $100,000 for any loss or damage to any Unit shall be paid to the
Indenture Trustee, so long as the Equipment Notes remain outstanding, and
thereafter to Lessor, in each case under a standard loss payable clause, and
(iii) 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) To the extent that the risk of loss with respect to the applicable
Units shall be borne by Persons (other than the Lessee) in possession or control
of such Unit and such other Person shall be obligated to pay a settlement amount
to Lessee in the amount of such loss in respect of such Unit, the Lessee may, in
lieu of maintaining the physical damage insurance required by Section 12.1(a),
self-insure with respect to any Units for such amounts and against such risks as
shall be based upon reasonable practices then in effect in the railcar leasing
and insurance industries.

         (c) The entire proceeds of any property insurance or third party
payments for damages to any Unit received by Lessor or the Indenture Trustee
under Section 12.2(a)(ii) 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

                                       24
<PAGE>

proceeds will be paid, so long as no Significant 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 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, the Policy
Provider and Loan Participant (iii) provide that neither Owner Participant,
Lessor, the Trust Company, the Policy Provider, 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, the Policy Provider 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 cease
to be available to Lessee in the commercial insurance market on commercially
reasonable terms (or Lessee shall receive notice that such policy or coverage
will cease to be available), Lessee shall give Lessor prompt written notice
thereof and 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 unanimously (x)
state that such

                                       25
<PAGE>

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.M. Best's" rating of A- or better for
railcars of similar type and capacity and (y) explain in detail the basis for
such conclusions. At any time after the granting of such waiver, but not more
often than twice 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) and any such waiver may specify an outside
expiration date, but such date shall not be earlier than one year after the date
of such waiver. If such supplemental report shows that such coverage is
available or Lessee otherwise learns that such coverage is again available,
Lessee shall within 90 days of such report or of receiving such knowledge obtain
such insurance coverage. Regardless of whether such a supplemental report has
been requested, Lessee shall give prompt written notice to Lessor if it learns
that any previously unavailable coverage with respect to which a waiver has been
granted is again available. 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 (ii) below, use
reasonable efforts to furnish) Lessor, the Indenture Trustee, Owner Participant,
the Policy Provider 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 hereof
(including, without limitation the deductible level described in Section
12.1(b)) and as set forth in Exhibits B-1 and B-2 to the Participation
Agreement, and (iii) 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 and the Policy Provider
shall each 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, the Policy Provider and
the Indenture Trustee, that all premiums due on such insurance have been paid.

                                       26
<PAGE>

         (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, the Policy Provider, 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 and Policy
Provider may attempt to obtain and provide satisfactory insurance and Lessee
shall reimburse Owner Participant and Policy Provider for reasonable 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 or Policy Provider 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, 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 each March 31, June 30, September 30 and December 31, with respect to clause
(c) below) thereafter, Lessee will furnish (or cause the Manager under the
Management Agreement to furnish) to Lessor, Owner Participant, Loan Participant,
the Indenture Trustee, Policy Provider and the Rating Agency an accurate
statement, as of the preceding December 31 (or, as of the end of the preceding
calendar quarter with respect to clause (c) below), (a) showing the amount,
description and reporting marks of the Units then leased hereunder, the amount,

the condition or repair of the Units as Lessor, Collateral Agent or Policy
Provider 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 the Units and the Other Units for the prior
calendar quarter as reported to the Manager by railroads (provided, that Lessee

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. Lessee will provide Lessor and Policy Provider with
prompt notice, but in any event within 30 days of (i) any legal proceeding
relating to any Unit or Pledged Unit, alleging that Lessee is liable for an
amount in excess of $5,000,000 or that Lessor, the Owner Participant, the
Indenture Trustee or the Policy Provider is alleged to be liable for an amount
in excess of $100,000, (ii) actual knowledge of or receipt of written notice
alleging that any Unit or Pledged Unit (or group of Units or Pledged Units)
violates any environmental law where the aggregate cost of placing such Unit or
Pledged Unit or group of Units or Pledged Units into compliance is likely to
exceed $100,000 or (iii) actual knowledge of or receipt of written notice of any
incident involving any Unit or Pledged Unit alleging personal injury or property
damage (including damage to the environment) including costs of remediation, in
excess of $1,000,000.

         Section 13.2 Inspection. (a) Each of the Lessor (and as assignee of
certain of Lessor's rights hereunder, the Control Party) and the Owner
Participant, together with the agents, representatives, accountants and legal
and other advisors of each of the foregoing (collectively, the "Inspection
Representatives"), shall have the right to (i) conduct a field examination of
the Units and the Pledged Units (each such inspection, a "Unit Inspection"),
(ii) (x) inspect all documents (the "Related Documents"), including, without
limitation, all leases, insurance policies, warranties or other agreements,
relating to the Units, the Pledged Units and the other Collateral (each such
inspection, a "Related Document Inspection") and (y) inspect each of the
Lessee's and the Manager's books, records and databases (which shall include
reasonable access to Lessee's and the Manager's computers and computer records
to the extent necessary to evaluate compliance with the Operative Agreements)
(collectively, the "Books and Records")

                                       28
<PAGE>

with respect to the Units, the Pledged Units and the other Collateral and the
Related Documents (including without limitation data supporting all reporting
requirements under the Operative Agreements) (each such inspection, a "Book and
Records Inspection") and (iii) discuss (x) the affairs, finances and accounts of
the Lessee (with respect to itself) and the Manager (with respect to itself and
the Lessee) and (y) the Units, the Pledged Units and the other Collateral, the
Related Documents and the Books and Records, in each case with the principal
executive officer and the principal financial officer of each of the Lessee and
the Manager, as applicable (the foregoing clauses (x) and (y) a "Company
Inspection") (the Unit Inspections, the Related Documents Inspections, the Books
and Records Inspections and the Company Inspections described in clauses (i),
(ii) and (iii), collectively, the "Inspections").

         (b) All Inspections shall be conducted upon reasonable request and
notice to Lessee (with respect to itself) and the Manager (with respect to
itself and the Lessee) and shall (a) be conducted during normal business hours,
(b) be subject to Lessee's and the Manager's customary security procedures, if
any, and (c) not unreasonably disrupt Lessee's or the Manager's business.

         (c) Each of the Lessor (and, as assignee of certain of Lessor's rights
hereunder, the Control Party) and the Owner Participant (together with their
respective Inspection Representatives) shall have the right to conduct
(independent of any inspection rights of any other party) (i) (x) one Unit
Inspection per calendar year, and in the case of each of the Policy Provider and
the Owner Participant, one additional Related Documents Inspection, Books and
Records Inspection and Company Inspection per calendar year for the calendar
years ending December 31, 2005 and December 31, 2006, in each case, at the sole
cost and expense of the Lessor, Control Party or Owner Participant, respectively
(as applicable), and (y) one Related Documents Inspection, one Books and Records
Inspection and one Company Inspection per calendar year at the sole cost and
expense of Lessor, the Control Party or Owner Participant, respectively (as
applicable) (including the reasonable legal and accounting fees, costs and
expenses incurred by the Lessor, Control Party or the Owner Participant, as
applicable, and their respective Inspection Representatives, as applicable)
(each such Inspection described in clauses (x) and (y), an "Ordinary Inspection"
and collectively, "Ordinary Inspections"); provided, that, notwithstanding the
foregoing, Lessee shall pay for or reimburse the Control Party (which amounts
shall constitute Supplemental Rent hereunder) for inspection costs incurred by
or on behalf of the Control Party pursuant to this paragraph (c).

         (d) If in connection with or as a result of any Ordinary Inspection,
Lessor, the Control Party or the Owner Participant, as applicable, determines,
in its reasonable discretion, that an Inspection Issue (as defined below) has
occurred, then Lessor, the Control Party or the Owner Participant, as
applicable, shall have the right, to (i) collect from Lessee the costs and
expenses of such Ordinary Inspection and (ii) conduct any type and number of
additional Inspections from time to time (each, an "Additional Inspection" and
collectively, "Additional Inspections") to confirm satisfactory resolution, in
the reasonable business judgment of the Lessor, Control Party or the Owner
Participant, as applicable, of any such Inspection Issues identified in such
Ordinary Inspection or Interim Inspection, or in any Additional Inspection in
connection therewith. All such Additional Inspections shall be at the sole cost
and expense of Lessee (including the reasonable legal and accounting fees, costs
and expenses incurred by Lessor, the Control Party or Owner Participant, as
applicable, and their respective Inspection

                                       29
<PAGE>

Representatives). For the purposes of this Section 13.2, "Inspection Issue"
means (x) any material misstatement or omission of fact in or with respect to
the Units, the Pledged Units, the Related Documents or the Company Inspections
or (y) a determination, in its reasonable business judgment, by Lessor, the
Control Party or the Owner Participant, as applicable, that the Related
Documents or Books and Records are incomplete or inaccurate in any material
respect.

         Without prejudice to the right to conduct Inspections, Lessor, the
Control Party and the Owner Participant shall confer with a view toward
coordinating their conduct with respect to the Inspections in order to minimize
the costs thereof and business disruption attendant thereto.

         Notwithstanding any of the foregoing, during the occurrence and
continuance of a Lease Event of Default, (i) there shall be no limit on the type
and number of Inspections that can be undertaken by Lessor, the Control Party or
the Owner Participant, as applicable, and their respective Inspection
Representatives and (ii) all costs and expenses of any Inspection shall be at
the sole cost and expense of the Lessee (including the reasonable legal and
accounting fees, costs and expenses incurred by the Control Party and the Owner
Participant, together with their respective Inspection Representatives).

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 (x) in the case of any such payment that is
required to be made on the Basic Term Expiration Date or on any date within 30
days before the Basic Term Expiration Date, when due, and (y) in the case of any
other such payment, 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; provided, further, that in the event
that the Special Equity Buy-Out has been consummated, failure to make 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 (to the extent such amount
constitutes an Accumulated Equity Deficiency Amount to be applied under Section
3.4, clause 9 of the Collateral Agency Agreement) shall, after receipt by Lessee
of written notice of such failure from Lessor or Owner Participant, be a Lease
Event of Default; or

                                       30
<PAGE>

         (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 (x) in the case of any such payment that is required to
be on the Basic Term Expiration Date or on any date within 30 days before the
Basic Term Expiration Date, when due, and (y) in the case of any other such
payment, after the same shall have become due and such failure shall continue
unremedied for 30 days after receipt by Lessee of written notice of such failure
from Lessor, Policy Provider, 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 (15) 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

         (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 Lessee's obtaining actual
knowledge 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) TILC (or any successor thereto in its capacity as Administrator or
Servicer, as applicable) shall have defaulted in any material respect in the
performance of any of its obligations under the Administrative Services
Agreement or the Servicing Agreement or a default shall occur under Section 6(a)
of the Account Administration Agreement, and, in each case, Lessee shall have
failed to exercise its rights thereunder in respect of such default for a period
of 30 days after receipt by Lessee of written notice from Lessor, Owner
Participant, Policy Provider or the Indenture Trustee, demanding that such
action be taken; or

         (f) Any representation or warranty made by Lessee in any Lessee
Agreement or any representation or warranty made by TILC in any Operative
Agreement to which any such Person is a party, in each case, other than the Tax
Indemnity Agreement, is untrue or incorrect in any material respect as of the
date of making thereof and such untruth or incorrectness shall continue to be
material and unremedied for a period of 30 days after receipt of notice from
Lessor, Owner Participant, Indenture Trustee or the Policy Provider; 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 120 days after receipt of notice from Lessor, Owner Participant, the
Indenture Trustee or the Policy Provider so long as Lessee, or TILC, 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

                                       31
<PAGE>

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 or
partnership 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, 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, Policy Provider 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 150 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; or

         (l) The Lessee shall have defaulted in any material respect in the
performance of any of its covenants and agreements contained in Section 2.8(b)
of the Collateral Agency Agreement and such default shall continue unremedied
for a period of 30 days; or

                                       32
<PAGE>

         (m) An amount equal to the Additional Liquidity Reserve Amount shall
not have been deposited into the Liquidity Reserve Account either (i) pursuant
to Section 3.4 of Collateral Agency Agreement (without withdrawal from the Cash
Trapping Account) or (ii) as a result of a direct capital contribution by TILC
or an Affiliate thereof (other than the Lessee) within ninety (90) days after
the occurrence of an Additional Liquidity Reserve Trigger.

         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 (to the extent
such Sublease has not been previously assigned 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

                                       33
<PAGE>

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);

         (d) (i) deliver notice under Section 5.2 and exercise all rights of the
"lessor" under the Subleases, including without limitation the right to direct
the applicable Sublessees to make rental payments to such account or accounts as
Lessor may specify, and (ii) 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
or (g) below 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 Stipulated Loss Amount for such
Unit computed as of the payment date specified in such notice as of the payment
date specified in such notice; and upon payment by Lessee pursuant to clause
(iii) of this Section 15.1(e) of such Stipulated Loss Amount, any Late Payment
Premium and of all other amounts (other than Basic

                                       34
<PAGE>

Rent due on such date) payable by Lessee under this Lease and under the other
Operative Agreements, including without limitation, all Policy Provider Amounts
and Policy Provider Reimbursement Costs in respect of such Unit, Lessor shall
transfer "as is" and "where is" and without recourse or warranty all right,
title and interest of Lessor in and to such Unit to Lessee or as it may direct,
and Lessor shall execute and deliver such documents evidencing such transfer as
Lessee shall reasonably request;

         (f) if Lessor shall have sold any Unit pursuant to paragraph (c) above,
Lessor, in lieu of exercising its rights under paragraph (e) above with respect
to such Unit may, if it shall so elect, demand that Lessee pay to Lessor, and
Lessee shall pay to Lessor, as liquidated damages for loss of a bargain and not
as a penalty (in lieu of the Basic Rent for such Unit due subsequent to the Rent
Payment Date next preceding such sale), any accrued and unpaid Rent for such
Unit as of the date of such sale (Basic Rent for this purpose accruing at a per
diem rate equal to the 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) (i) Lessor may terminate this Lease with respect to all of the
Units, (ii) Lessor may terminate the leasing of any or all Units under any
Sublease (subject to the provisions of any applicable Sublease and subject to
Section 8 of the Participation Agreement) and/or (iii) Lessor 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 Lessor, Indenture Trustee and Policy
Provider 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 and Lessor shall pay to Lessee an amount equal to 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 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

                                       35
<PAGE>

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.

         In addition, after the occurrence and during the continuation of a
Lease Event of Default, Lessee will pay or reimburse Lessor and its assignees
(including the Indenture Trustee, the Pass Through Trustee and the Policy
Provider) for all of their respective costs and expenses (including reasonable
costs and expenses of counsel and other professionals) incurred in connection
with (i) the enforcement, defense or preservation of any rights in respect of
this Lease and the other Operative Agreements, including, without limitation,
any insolvency proceeding of Lessee or any of its Affiliates, and (ii) the
negotiation of any restructuring or "work-out", whether or not consummated, of
any obligations under, or transactions contemplated by, this Lease and the other
Operative Agreements.

         Section 15.2 Cumulative Remedies. The remedies in this Lease provided
in favor of Lessor shall not be deemed exclusive, but shall be cumulative and
shall be in addition to all other remedies in its favor existing at law or in
equity.

         Lessee hereby waives any mandatory requirements of law, now or
hereafter in effect, which might limit or modify any of the remedies herein
provided, to the extent that such waiver is permitted by law. Lessee hereby
waives any and all existing or future claims of any right to assert any offset
or counterclaim against the Rent payments due hereunder, and agrees to make the
rent payments regardless of any offset or counterclaim or claim which may be
asserted by Lessee on its behalf in connection with the lease of the 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, Policy Provider, 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 with respect to any Units
pursuant to this

                                       36
<PAGE>

Section 15 and shall have provided to Lessee the written demand specified in
Section 15.1(b) with respect to such Units, 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 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 than 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.

foregoing, in no event shall Lessee or any of its Affiliates be required to take

Partnership in the Partnership's jurisdiction of formation and/or other similar

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
propose of this Lease and to establish and protect the rights and remedies
created or intended to be created in favor of Lessor, the Participants, the
Policy Provider 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 Partnership's jurisdiction of
formation and/or other similar filings with the STB, the Registrar General of
Canada and any applicable Canadian provinces covering all Subleases generally
and delivery of original copies of the applicable Subleases in the manner set
forth in the Collateral Agency Agreement.

         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

                                       38
<PAGE>

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, shad 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 and
acknowledge that concurrently with the execution and delivery of this Lease,
Lessor has executed and delivered to the Indenture Trustee the Indenture, which,
among other things, assigns as collateral security and grants a security
interest in favor of the Indenture Trustee in, to and under all right, title and
interest of Lessor in and to this Lease and certain of the Rent payable
hereunder (excluding Excepted Property), all Equipment and all Subleases, all as
more explicitly set forth in the Indenture. Lessee acknowledges the Indenture
Trustee's rights under the Indenture including without limitation, the right of
the Indenture Trustee to receive from the Lessee copies of all notices,
certificates, reports, filings, opinions of counsel and other documents and all
information which Lessee is permitted or required to give or furnish to Lessor
pursuant to this Lease. Lessor agrees that it shall not otherwise assign or
convey its right, title and interest in and to this Lease or any Unit, nor
amend, modify or waive any provision of this Lease, in each case, except as
expressly permitted by and subject to the provisions of the Participation
Agreement, the Trust Agreement and the Indenture.

                                       39
<PAGE>

         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, the Administrator under the Administrative Services 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, or (iv) shall relieve Lessee of
any liability or obligation hereunder. 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.

         (a) This Lease is a net lease and Lessee's obligation to pay all Rent
payable hereunder shall be absolute, unconditional and irrevocable and shall not
be affected by any circumstance of any character including, without limitation,
(i) any set-off, abatement, counterclaim, suspension, recoupment, reduction,
rescission, defense or other right that Lessee may have against Lessor, Owner
Participant, the Indenture Trustee or any holder of an Equipment Note or Pass
Through Certificate, any vendor or manufacturer of any Unit, or any other Person
for any reason whatsoever, (ii) any defect in or failure of title,
merchantability, condition, design, compliance with specifications, operation or
fitness for use of all or any part of any Unit, (iii) any damage to, or removal,
abandonment, requisition, taking, condemnation, loss, theft or destruction of
all or any part of any Unit or any interference, interruption, restriction,
curtailment or cessation in the use or possession of any Unit by Lessee or any
other Person for any reason whatsoever or of whatever duration, (iv) any
insolvency, bankruptcy, reorganization or similar proceeding by or against
Lessee, Lessor, Owner Participant, the Indenture Trustee, Loan Participant, any
holder of an Equipment Note or Pass Through Certificate or any other

                                       40
<PAGE>

Person (and no payment of any Rent hereunder shall be considered paid or applied
to the extent that, at any time, all or any portion of such payment or
application is rescinded by application of law or judicial authority, or must
otherwise be returned or refunded for any reason), (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 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.

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 22. Purchase Options; Renewal Option.

         Section 22.1 Early Purchase Option. In addition to the option granted

<PAGE>

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 and transfer and sales taxes 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 in respect of the applicable Units shall cease and the
Lease Team shall terminate with respect thereto.

         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 Trust's obligations under the Indenture and its obligations under the
Policy Provider Documents to which the Owner Trust is a party as provided in
Section 3.6 of the Indenture to the extent such obligations become due after the
date of exercise of such purchase option; 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. 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, Policy Provider
and Indenture Trustee as a result of the notice given by Lessee pursuant to this
Section.

         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 in respect of the purchased Units (as
a rebate of Basic Rent and not as a reduction in the applicable 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 in respect of such purchased Units (as a
payment of additional Basic Rent).

         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

                                       44
<PAGE>

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 360 days and not more than 720 days prior to the end
of the Basic Term or the Renewal Term, Lessee shall give Lessor notice of its
decision to return or retain the Units (it being understood that at the end of
the Basic Term or the Renewal Term Lessee must return all of such Units or
retain all of such Units at the end of the Basic Term or the 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 360 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 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, Lessee shall have the right and, upon the giving of such
notice under this Section 22.3, the obligation to purchase all of the Units at a
price equal to the greater of (i) Fair Market Sales Value of such Units and (ii)
$17,019,360, at the expiration of the Basic Term, or, if a Renewal Term is then
in effect, at the end of such Renewal Term at a price equal to the Fair Market
Sales Value of such Units, plus, in each case, 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 so long as the Policy remains in effect without
withdrawal from any Reserve Account (or the Special Reserves Account or
Transition Expense Account, as such terms are defined in the Collateral Agency
Agreement), 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) and all then unpaid Policy Provider
Amounts and, without duplication, all then unpaid Policy Provider Reimbursement
Costs, in each case, as defined in this Lease and as defined in the Other Lease
described in clause (i) of the definition thereof. Lessee shall give Lessor
written notice not less than 360 days and not more than 720 days prior to the
end of the Basic Term or the 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 (including,
without limitation, all then unpaid Policy Provider Amounts and, without
duplication, all then unpaid Policy Provider Reimbursement Costs, in each case,
as defined in this Lease and as defined in the Other Lease described in clause
(i) of the definition thereof 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 Lease Event of Default shall
have occurred and be continuing and Lessee shall have duly given the notice
required by Section 22.2 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. Lessee may exercise this renewal option by giving
Lessor written notice not less than 360 days and not more than 720 days prior to
the end of the Basic Term that Lessee elects to renew this Lease with respect to
the Units then leased hereunder. Such renewal shall be for a renewal term of two
years. The Basic Rent for each Unit during the Renewal Term (the "Renewal Rent")
shall be the greater of (a) $709,140.00, payable monthly in arrears and (b) the
Fair Market Rental Value determined as of the commencement of the Renewal Term.
The Renewal Term shall commence immediately upon the expiration of the Basic
Term.

         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 Units at the end of the Basic Term or the Renewal Term (and, in any
event, if it is anticipated that there will be any Extended Units at the end of
the Basic Term), Lessor and Lessee shall determine (a) if Lessee shall have
exercised the purchase option under Section 22.3, 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 (b) if Lessee shall have exercised its
renewal option pursuant to Section 22.4, the Fair Market Rental Value of the
applicable Units as of the end of the Basic Term 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 the 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 the Renewal Term, reduced
in equal monthly increments to the Fair Market Sales Value of such Unit as of
the last day of the Renewal Term; provided that in no event during any Renewal
Term shall the Stipulated Loss Amount and Termination Amount of any Unit be less
than 20% of the Equipment Cost of such Unit.

SECTION 23. Limitation of Lessor's Liability.

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

                                       47
<PAGE>

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. Subject to and in accordance with
the terms of the Indenture, 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.

         Section 25.7 Survival. All warranties, representations, indemnities,
payment obligations (including without limitation, the obligations of the Lessee
to pay Basic Rent and Supplemental Rent), covenants and agreements made by
either party hereto, herein or in any certificate or other instrument delivered
by such party or on the behalf of any such party under this Lease, shall be
considered to have been relied upon by the other party hereto and shall survive
the consummation of the transactions contemplated hereby on the Closing Date
regardless of any investigation made by either such party or on behalf of either
such party, and to the extent having accrued and not been paid, having been
required to be performed and not having been performed 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, the Insurance Agreement with the Insurance Manager
and the Administrative Services Agreement with the Administrator, 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, the Insurance Manager and the Administrator to take such actions as
shall be necessary or appropriate under

                                       48
<PAGE>

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.

         Section 25.11 No Partnership Created. The parties hereto do not intend
to create, and nothing herein shall be construed as creating, a partnership or
joint venture for federal income tax purposes. Each party hereto agrees (i) that
it does not have, or intend to form, a joint profit motive with any other party
hereto or any other person with respect to any Unit, Existing Equipment Sublease
or Permitted Sublease, (ii) not to hold itself out to the public as a partner
with any other party hereto, (iii) not to share any profits (including rent or
any other payments to which it is entitled) or losses with respect to its
interest in any Unit, Existing Equipment Sublease or Permitted Sublease, and
(iv) that unless (x) otherwise required by the Internal Revenue Service or like
governmental authority with jurisdiction over income tax matters (the "Required
Position") or (y) such party receives an opinion of its independent tax counsel
that there is no "reasonable basis" (within the meaning of Treasury Regulation
Section 1.6662-3(b)(3)) to claim that no partnership exists (and such party
delivers notice of the receipt of such opinion or notice of the Required
Position to the other parties hereto within ten (10) Business Days after its
receipt of such opinion or notice of the Required Position), it will not file
any partnership or other joint income tax return with respect to items of
income, loss, deduction, or credit attributable to its interest in any Unit,
Existing Equipment Sublease or Permitted Sublease.
