                  (a) Lessee (i) is a duly organized and validly existing
corporation in good standing under the laws of the jurisdiction of its
incorporation, (ii) has the corporate power and authority to own its property
and assets and to transact the business in which it is engaged and presently
proposes to engage and (iii) is duly qualified and is authorized to do business
and is in good standing in each jurisdiction where the ownership, leasing or
operation of its property or the conduct of its business requires such
qualifications except for failures to be so qualified which, individually or in
the aggregate, could not reasonably be expected to have a Material Adverse
Effect or a material adverse effect on Lessee's ability to perform its
obligations under the Operative Documents.

                  (b) Lessee has the corporate power and authority to execute,
deliver and perform the terms and provisions of each of the Operative Documents
to which it is party and has taken all necessary corporate action to authorize
the execution, delivery and performance by it of each of such Operative
Documents. Lessee has duly executed and delivered each of the Operative
Documents to which it is party, and each of such Operative Documents constitutes
its legal, valid and binding obligation enforceable in accordance with its
terms, except to the extent that the enforceability thereof may be limited by

reorganization, moratorium or other similar laws generally affecting creditors'
rights and by equitable principles (regardless of whether enforcement is sought
in equity or at law).

                  (c) Neither the leasing of the Equipment, the execution,

                  (s) [Reserved]

                  (t) No Item of Equipment is intended by Lessee to be
"equipment used in farming operations" as such terms are used in Section 9-401
of the New York Uniform Commercial Code or any correlative provision of any
other applicable state's Uniform Commercial Code and no Item of Equipment shall
be "goods covered by a certificate of title issued under a statute of this state
or of another jurisdiction under the law of which indication of a security
interest on the certificate is required as a condition of perfection" within the
meaning of Section 9-103 of the New York Uniform Commercial Code or any
correlative provision of any other applicable state's Uniform Commercial Code.

                  (u) The audited consolidated balance sheet of Guarantor and
its consolidated subsidiaries as at March 31, 2001 and the related consolidated
statement of income, stockholders' equity and cash flow of Guarantor and its
consolidated subsidiaries for the fiscal year ended on said date, with the
opinion thereon of Deloitte Touche heretofore furnished to Lessor, each Tranche
B Lender and Administrative Agent are complete and correct and fairly present
the consolidated financial condition of Guarantor and its consolidated
subsidiaries as at said dates and the results of its operations for the fiscal
year on said dates in all material respects, all in accordance with GAAP, as
applied on a consistent basis. Neither Lessee nor any Subsidiary has on the
Amendment Date any material Debt, contingent liabilities, liabilities for taxes,
unusual forward or long-term commitments or unrealized or anticipated losses
from any unfavorable commitments, except as referred to or reflected or provided
for in the Financial Statements or in Schedule 5. Since March 31, 2001, there
has been no change or event having a Material Adverse Effect. Since the date of
the Financial Statements, neither the business nor the Properties of Lessee or
any Subsidiary have been materially and adversely affected as a result of any
fire, explosion, earthquake, flood, drought, windstorm, accident, strike or
other labor disturbance, embargo, requisition or taking of Property or
cancellation of contracts, permits or concessions by any Governmental Equity,
riot, activities of armed forces or acts of God or of any public enemy. With
respect to the Closing Date and the Amendment Date, notwithstanding anything
contained herein to the contrary, the "Financial Statements" referenced in this
Section 2.1(u) and in Sections 9.3(f) and 9.3(h) are the proforma financial
statements contained in the Offering Memorandum which gives effect to the Merger
and for each Funding Date thereafter, notwithstanding anything contained herein
to the contrary, such "Financial Statements" are the Financial Statements
identified as such in the Participation Agreement Supplement for such Funding
Date.

                  (v)      ERISA.

                           (i) Lessee, each Subsidiary and each ERISA Affiliate
         have complied in all material respects with ERISA and, where
         applicable, the Code regarding each Plan.

                           (ii) Each Plan is, and has been, maintained in
         substantial compliance with ERISA and, where applicable, the Code.

                           (iii) No act, omission or transaction has occurred
         which could result in imposition on Lessee, any Subsidiary or any ERISA
         Affiliate (whether directly or indirectly) of

                                      -5-
<PAGE>

         (i) either a civil penalty assessed pursuant to section 502(c), (i) or
         (l) of ERISA or a tax imposed pursuant to Chapter 43 of Subtitle D of
         the Code or (ii) breach of fiduciary duty liability damages under
         section 409 of ERISA.

                           (iv) No Plan (other than a defined contribution plan)
         or any trust created under any such Plan has been terminated since
         September 2, 1974. No liability to the PBGC (other than for the payment
         of current premiums which are not past due) by Lessee, any Subsidiary
         or any ERISA Affiliate has been or is expected by Lessee, any
         Subsidiary or any ERISA Affiliate to be incurred with respect to any
         Plan. No ERISA Event with respect to any Plan has occurred.

                           (v) Full payment when due has been made of all
         amounts which Lessee, any Subsidiary or any ERISA Affiliate is required
         under the terms of each Plan or applicable law to have paid as
         contributions to such Plan, and no accumulated funding deficiency (as
         defined in section 302 of ERISA and section 412 of the Code), whether
         or not waived, exists with respect to any Plan.

                           (vi) The actuarial present value of the benefit
         liabilities under each Plan which is subject to Title IV of ERISA does
         not, as of the end of Lessee's most recently ended fiscal year, exceed
         the current value of the assets (computed on a plan termination basis
         in accordance with Title IV of ERISA) of such Plan allocable to such
         benefit liabilities. The term "actuarial present value of the benefit
         liabilities" shall have the meaning specified in section 4041 of ERISA.

                           (vii) None of Lessee, any Subsidiary or any ERISA
         Affiliate sponsors, maintains, or contributes to an employee welfare
         benefit plan, as defined in section 3(1) of ERISA, including, without
         limitation, any such plan maintained to provide benefits to former
         employees of such entities, that may not be terminated by Lessee, a
         Subsidiary thereof or any ERISA Affiliate in its sole discretion at any
         time without any material liability.

                           (viii) None of Lessee, any Subsidiary or any ERISA
         Affiliate sponsors, maintains or contributes to, or has at any time in
         the preceding six (6) calendar years, sponsored, maintained or
         contributed to, any Multiemployer Plan.

                           (ix) None of Lessee, any Subsidiary or any ERISA
         Affiliate is required to provide security under section 401(a)(29) of
         the Code due to a Plan amendment that results in an increase in current
         liability for the Plan.

                           (x) Assuming the accuracy at all times of the
         representation and warranty of each Tranche B Lender in Section 2.6 of
         this Agreement, the execution and delivery of this Agreement will be
         exempt from, or will not involve any transaction which is subject to,
         the prohibitions of either Section 406 of ERISA or Section 4975 of the
         Code and will not involve any transaction in connection with which a
         penalty could be imposed under Section 502(i) of ERISA or a tax could
         be imposed pursuant to Section 4975 of the Code.

                  (w) Taxes. Except as set out in Schedule 6, each of Lessee and
its Subsidiaries has filed all United States federal income tax returns and all
other tax returns which are required to be filed by them and have paid all
material taxes due pursuant to such returns or pursuant to any assessment
received by Lessee or any Subsidiary. The charges, accruals and reserves on the
books of Lessee and its Subsidiaries in respect of taxes and other governmental
charges are, in the opinion of Lessee, adequate. No tax lien has been filed and,
to the knowledge of Lessee, no claim is being asserted with respect to any such
tax, fee or other charge.

                  (x)      Titles, etc.

                           (i) Except as set out in Schedule 7, Lessee and its
         Subsidiaries have good and marketable title to its material properties
         (i) except in cases where the failure to have said good and marketable
         title would not reasonably cause a Material Adverse Effect and (ii)
         free and clear of all Liens, except Liens permitted by Section 9.3(g).

                           (ii) All leases and agreements necessary for the
         conduct of the business of Lessee and its Subsidiaries are valid and
         subsisting, in full force and effect and there exists no default or
         event or circumstance which with the giving of notice or the passage of
         time or both would give rise to a default under any such lease or
         leases, which would affect in any material respect the conduct of the
         business of Lessee and its Subsidiaries.

                           (iii) Rights, Properties and other assets presently
         owned, leased or licensed by Lessee or its Subsidiaries including,
         without limitation, all easements and rights of way, include all
         rights, Properties and other assets necessary to permit Lessee or its
         Subsidiaries to conduct their business in all material respects in the
         same manner as its business has been conducted prior to the date of
         this representation.

                           (iv) All of the assets and Properties of Lessee or
         its Subsidiaries thereof which are reasonably necessary for the
         operation of its business are in good working condition and are
         maintained in accordance with prudent business standards.

                  (y) No Material Misstatements. No written information,
statement, exhibit, certificate, document or report furnished to Administrative
Agent and the Tranche B Lenders (or any of them) by Lessee or any Subsidiary in
connection with the negotiation of this Agreement contained any material
misstatement of fact or omitted to state a material fact or any fact necessary
to make the statement contained therein not materially misleading in the light
of the circumstances in which made and with respect to Lessee and its
Subsidiaries taken as a whole. To Lessee's knowledge, there is no fact peculiar
to Lessee or any Subsidiary which has a Material Adverse Effect or in the future
is reasonably likely to have (so far as Lessee can now reasonably foresee) a
Material Adverse Effect and which has not been set forth in this Agreement or
the other documents, certificates and statements furnished to Administrative
Agent by or on behalf of Lessee or any Subsidiary or otherwise prior to, or on,
the date of this representation in connection with the transactions contemplated
hereby.

                  (z) Investment Company Act. Neither Lessee nor any Subsidiary

within the meaning of the Investment Company Act of 1940, as amended.

                  (aa) Public Utility Holding Company Act. Neither Lessee nor
any Subsidiary is a "holding company," or a "subsidiary company" of a "holding
company," or an "affiliate" of a "holding company" or of a "subsidiary company"
of a "holding company," or a "public utility" within the meaning of the Public
Utility Holding Company Act of 1935, as amended.

                  (bb) Subsidiaries. Except as set forth on Schedule 3, Lessee
has no Subsidiaries.

                  (cc) Defaults. Neither Lessee nor any Subsidiary is in
material default nor has any event or circumstance occurred which, but for the
expiration of any applicable grace period or the giving of notice, or both,
would constitute a material default under any material agreement or instrument
to which Lessee or any Subsidiary is a party or by which Lessee or any
Subsidiary is bound which default would have a Material Adverse Effect.

                  (dd) Environmental Matters. Except (i) as provided in Schedule
8 or (ii) as would not have a Material Adverse Effect (or with respect to (c),
(d) and (e) below, where the failure to take such actions would not have a
Material Adverse Effect):

                           (i) Neither any Property of Lessee or any Subsidiary
         nor the operations conducted thereon violate any order or requirement
         of any court or Governmental Entity or any Environmental Law;

                           (ii) Without limitation of clause (a) above, no
         Property of Lessee or any Subsidiary nor the operations currently
         conducted thereon or, to the best knowledge of Lessee, by any prior
         owner or operator of such Property or operation, are in violation of or
         subject to any existing, pending or threatened action, suit,
         investigation, inquiry or proceeding by or before any court or
         Governmental Entity or to any remedial obligations under Environmental
         Laws;

                           (iii) All notices, permits, licenses or similar
         authorizations, if any, required to be obtained or filed in connection
         with the operation or use of any and all Property of Lessee and each
         Subsidiary, including without limitation past or present treatment,
         storage, disposal or release of a hazardous substance or solid waste
         into the environment, have been duly obtained or filed, and Lessee and
         each Subsidiary are in compliance with the terms and conditions of all
         such notices, permits, licenses and similar authorizations;

                           (iv) All hazardous substances, solid waste, and oil
         and gas exploration and production wastes, if any, generated at any and
         all Property of Lessee or any Subsidiary have in the past been
         transported, treated and disposed of in accordance with Environmental
         Laws and so as not to pose an imminent and substantial endangerment to
         public health or welfare or the environment, and, to the best knowledge
         of Lessee, all

                                      -8-
<PAGE>

         such transport carriers and treatment and disposal facilities have been
         and are operating in compliance with Environmental Laws and so as not
         to pose an imminent and substantial endangerment to public health or
         welfare or the environment, and are not the subject of any existing,
         pending or threatened action, investigation or inquiry by any
         Governmental Entity in connection with any Environmental Law;

                           (v) Lessee has taken all steps reasonably necessary
         to determine and has determined that no hazardous substances, solid
         waste, or oil and gas exploration and production wastes, have been
         disposed of or otherwise released and there has been no threatened
         release of any hazardous substances on or to any Property of Lessee or
         any Subsidiary except in compliance with Environmental Laws and so as
         not to pose an imminent and substantial endangerment to public health
         or welfare or the environment;

                           (vi) To the extent applicable, all Property of Lessee
         and each Subsidiary currently satisfies all design, operation, and
         equipment requirements imposed by the OPA or scheduled to be imposed by
         OPA during the term of the Lease Agreement, and Lessee does not have
         any reason to believe that such Property, to the extent subject to OPA,
         will not be able to maintain compliance with the OPA requirements
         during the term of the Lease Agreement; and

                           (vii) Neither Lessee nor any Subsidiary has any known
         contingent liability in connection with any release or threatened
         release of any oil, hazardous substance or solid waste into the
         environment.

                  (ee) Compliance with the Law. Neither Lessee nor any
Subsidiary has violated any Governmental Requirement or failed to obtain any
license, permit, franchise or other governmental authorization necessary for the
ownership of any of its Properties or the conduct of its business, which
violation or failure would have (in the event such violation or failure were
asserted by any Person through appropriate action) a Material Adverse Effect.

                  (ff) Insurance. Schedule 4 attached hereto contains an
accurate and complete description of all material policies of fire, liability,
workmen's compensation and other forms of insurance owned or held by Lessee and
each Subsidiary. All such policies are in full force and effect, all premiums
with respect thereto covering all periods up to and including the date of the
closing have been paid, and no notice of cancellation or termination has been
received with respect to any such policy. Such policies are sufficient for
compliance with all requirements of law and of all agreements to which Lessee or
any Subsidiary is a party; are valid, outstanding and enforceable policies;
provide adequate insurance coverage in at least such amounts and against at
least such risks (but including in any event public liability) as are usually
insured against in the same general area by companies engaged in the same or a
similar business for the assets and operations of Lessee and each Subsidiary;
will remain in full force and effect through the respective dates set forth in
the binders for said insurance without the payment of additional premiums; and
will not in any way be affected by, or terminate or lapse by reason of, the
transactions contemplated by this Agreement. Neither Lessee nor any Subsidiary
has been refused any insurance with respect to its assets or operations, nor has
its coverage been limited

                                      -9-
<PAGE>

below usual and customary policy limits, by an insurance carrier to which it has
applied for any such insurance or with which it has carried insurance during the
last three (3) years.

                  (gg) Hedging Agreements. Schedule 9 sets forth a true and
complete list of all Hedging Agreements as of the Amendment Date (including
commodity price swap agreements, forward agreements or contracts of sale which
provide for prepayment for deferred shipment or delivery of oil, gas or other
commodities) of Lessee and each Subsidiary, the material terms thereof
(including the type, term, effective date, termination date and notional amounts
or volumes), the net mark to market value thereof, all credit support agreements
relating thereto (including any margin required or supplied), and the counter
party to each such agreement.

                  (hh) Restriction on Liens. Except as set forth on Schedule 10,
neither Lessee nor any of Subsidiary is a party to any agreement or arrangement
(other than the Operative Documents, the Revolver and the Security Instruments),
or subject to any order, judgment, writ or decree, which either restricts or
purports to restrict its ability to grant Liens to other Persons on or in
respect of their respective assets or Properties.

                  (ii) As of each Funding Date, the projections identified on
the Participation Agreement Supplement for such Funding Date (or in the case of
the first Funding Date, the projections made a part of the final Offering
Memorandum of the Lessor dated February 6, 2001 furnished to the Administrative
Agent, the Lessor, the Indenture Trustee and the Tranche B Lenders prior to the
Closing Date) (the "Projections") have been prepared in good faith and are based
on reasonable assumptions, and there are no statements or conclusions in the
Projections which are based upon or include information known to Lessee to be
misleading in any material respect or which fail to take into account material
information known to Lessee regarding the matters reported therein. Lessee
believes that the Projections are reasonable and attainable, it being recognized
by Lessor and Tranche B Lenders, however, that projections as to future events
are not to be viewed as facts and that the actual results during the period or
periods covered by the Projections may differ from the projected results and
that the differences may be material.

                  (jj) Lessee has no knowledge of the falsity of, or any reason
to believe, any of the representations of Lessor and Co-Obligor contained in any
Note Purchase Agreement or Underwriting Agreement are untrue or incorrect in any
material respect.

                  (kk) There has been no change to the written description of
Lessee Maintenance Practices delivered to the Administrative Agent prior to the
Amendment Date, except as otherwise provided on the related Participation
Agreement Supplement for the most recent Funding Date.

                  2.1A Further Lessee Representations and Warranties. Lessee
hereby represents as of each Funding Date for the benefit of each other party
hereto as follows:

                  (z) Lessor shall have received such other confirmatory
assignments, conveyances, financing and continuation statements, transfer
endorsements and other assurances or instruments other than estoppel
certificates or other agreements, certificates or other documents to be
delivered by any Sublessee or other Person (other than an Affiliate of Lessee)
which Lessor may reasonably request to perfect, preserve or protect Lessor's
security interest granted under

Section 9 of the Lease Agreement, in form and substance satisfactory to Lessor,
as Lessor may reasonably request in writing at least five (5) Business Days
before such Funding Date.

                  The leasing of each Item of Equipment by Lessee hereunder
shall constitute a representation and warranty by Lessee as of the date such
leasing commences that the conditions contained in Section 3.1 have been
satisfied.

                  3.2. Tranche B Lender Conditions. No Tranche B Lender shall
have any obligation to make a Tranche B Loan for the acquisition of any Subject
Item hereunder unless on or before the Funding Date therefor each of the
following conditions are fulfilled:

                  (a) The conditions precedent to Lessor's obligation to lease

with respect thereto.

                  (b) There shall exist no Loan Default or Loan Event of Default

Tranche B Loan on such Funding Date shall have funded its pro rata share of the
Tranche B Loans to be funded on such Funding Date based upon its Tranche B

Lender does not exceed its Tranche B Commitment.

                  (d) Such Tranche B Lender shall have received original
counterparts (unless otherwise specified) in each case duly authorized, executed

                  (e) Such Tranche B Lender shall have received from Lessor, in
form and substance satisfactory to such Tranche B Lender, a copy of Lessor's

                  (f) Such Tranche B Lender shall have received from Lessor

Lessor General Partner's Certificate of Incorporation, By-Laws, and resolutions

an incumbency certificate

                                      -20-
<PAGE>

behalf of Lessor General Partner.

                  (g) Such Tranche B Lender shall have received a certificate in
form and substance satisfactory to such Tranche B Lender dated such Funding Date
from Lessor General Partner, the truth and accuracy of which shall be a
condition to the obligation of such Tranche B Lender to make its Tranche B Loan,
confirming that each of the representations and warranties of Lessor and Lessor
General Partner set forth in Sections 2.3, 2.4 and 2.5 are true and correct as
if made on and as of such date except to the extent such representations and
warranties expressly provide that they relate solely to an earlier date.

                  (h) Such Tranche B Lender shall have received written opinions
of counsel to Lessor and Lessor General Partner dated such Funding Date and
addressed to Indenture Trustee, the Initial Purchasers of the Tranche A Notes to

Date from the State of Delaware.

                  (j) Administrative Agent shall have received, in each case

confirmatory assignments, conveyances, financing and continuation statements,
transfer endorsements and other assurances or instruments other than estoppel
certificates or other agreements, certificates or other documents to be
delivered by any Sublessee or other Person (other than an Affiliate of Lessee)
which Majority Lenders may reasonably request to perfect, preserve or protect
Collateral Agent's security interest granted hereunder, in form and substance
satisfactory to Majority Lenders as Majority Lenders may reasonably request in
writing at least five (5) Business Days before such Funding Date.

                  4. Commitments and Fundings.

                  4.1. Tranche B Commitments. Subject to and upon the terms and
conditions set forth in Section 3 for the benefit of Tranche B Lenders, each
Tranche B Lender agrees to make on a Funding Date a single, non-revolving loan
to Lessor in an aggregate principal amount up to the amount of its Tranche B
Commitment set forth on the Participation Agreement Supplement for such Funding
Date (each such loan, a "Tranche B Loan"). Each party hereto agrees that, except
as provided below, no Tranche B Lender shall be required to make any Tranche B
Loan on any Funding Date hereunder in an amount in excess of its pro rata share
(based upon the aggregate of the Tranche B Commitments) of the aggregate Tranche
B Components to be funded on such Funding Date. Each Tranche B Lender's
obligation hereunder is several, such that the failure of any Tranche B Lender
to make a Tranche B Loan or satisfy any other obligation shall not relieve any
other Tranche B Lender of its obligations hereunder, and if

                                      -21-
<PAGE>

any Tranche B Lender with a commitment to make a Tranche B Loan on any Funding
Date shall fail to make a Tranche B Loan on such date each other Tranche B
Lender shall make an additional Tranche B Loan in an amount equal to its pro
rata share (based upon the aggregate of the Tranche B Commitments for such
Funding Date of the non-defaulting Tranche B Lenders) of the Tranche B Loan that
was to have been made by the defaulting Tranche B Lender, provided that the
maximum aggregate amount of Tranche B Loans that any Tranche B Lender shall be
obligated to make on any Funding Date shall not exceed its Tranche B Commitment
set forth on the Participation Agreement Supplement for such Funding Date. Any
Tranche B Loan made by another Tranche B Lender of a portion of a Tranche B Loan
to have been made by a defaulting Tranche B Lender shall not relieve such
defaulting Tranche B Lender of its obligations hereunder. If the conditions to
the obligations of any Tranche B Lender specified in Section 3.2 have not been
fulfilled or waived by it on or before the Commitment Termination Date at the
time in effect, such Tranche B Lender shall be relieved of all further
obligations to make any Tranche B Loan. Nothing in this Section 4.1 shall
operate to relieve Lessor, Lessee or Guarantor from their respective obligations
under the Operative Documents or to waive any Tranche B Lender's rights against
Lessor, Lessee or Guarantor.

                  4.2. Lessor Commitment to Purchase. Subject to and upon the
terms and conditions herein set forth for the benefit of Lessor, Lessee may
cause Sellers to sell to Lessor on any Funding Date and in such event Lessor
agrees to buy for the Acquisition Cost thereof and lease to Lessee on such
Funding Date certain natural gas compressor equipment. If the conditions to the
obligations of Lessor in Section 3.1 have not been fulfilled or waived by it on
or before the Commitment Termination Date at the time in effect, Lessor shall be
relieved of all further obligations to acquire from or lease to Lessee any
natural gas compressor equipment.

                  4.3. Lease Supplements. Upon the sale and lease of an Item of
Equipment in accordance with Section 4.2 Lessee shall execute and deliver to
Lessor a Lease Supplement for such Item of Equipment which Lease Supplement upon
satisfaction of the conditions precedent in Section 3.1 shall thereafter be
executed by Lessor and a signed counterpart provided to Lessee. Upon execution
and delivery by Lessee of such Lease Supplement, such Item of Equipment shall
automatically become in accordance with this Section 4.3 subject to the Lease
Agreement and an "Item of Equipment" thereunder.

                  4.4. Rights in Equipment. Upon the execution and delivery by
Lessee of a Lease Supplement relating to an Item of Equipment and satisfaction
of the other applicable conditions precedent set forth in Section 3, Lessor
shall have good and marketable title to such Item of Equipment subject only to
Permitted Liens and Lessor Liens and shall be obligated to pay or reimburse
Lessee in full for the Acquisition Cost of such Item of Equipment in accordance
with the provisions of this Agreement, provided that nothing in this Section 4.4
shall affect in any manner the respective rights and obligations of Lessor and
Lessee under the Lease Agreement or shall reduce or diminish any claim or remedy
for damages which Lessor or Lessee might assert for any breach or violation of
the terms of the Lease Agreement or of this Agreement.

                  4.5. Funding Dates. Each Funding Date after the Closing Date
shall occur only during a Commitment Period and, unless otherwise provided on
the related Participation

                                      -22-
<PAGE>

Agreement Supplement, there shall be no more than one Funding Date during any
Commitment Period.

                  4.6. Limitation on Size of Facility. Notwithstanding anything
to the contrary in the Operative Documents, the aggregate of all Tranche A Notes
at any time issued and all Tranche B Loans and Equity Contributions at any time
made shall not exceed $793,000,000.

                  5. Selection of Floating Lease Payment Period.

                  Provided no lease Event of Default shall have occurred and is
continuing Lessee shall at least three (3) LIBOR Banking Days prior to each
Floating Payment Date (other than a Floating Payment Date in the third-month of
a six-month LIBOR Floating Payment Period) deliver to Lessor written irrevocable
notice of its election to have both the Applicable Equity Rate and the
Applicable Tranche B Rate components of Floating Lease Payments for all Items of
Equipment be based on one-month, two-month, three-month, or six-month LIBOR or
on the Alternate Rate and Lessor shall promptly deliver notice of such election
to Administrative Agent. The Floating Lease Period based on one-month,
two-month, three-month or six-month LIBOR shall commence on such Floating
Payment Date and shall end on the calendar date corresponding to the first day
of such Floating Lease Period in the first, second, third or six month after
such Floating Payment Date, respectively; provided however, if such day is not a
LIBOR Banking Day, then the last day of such Floating Lease Period shall be the
next LIBOR Banking Day, provided further, if such next LIBOR Banking Day would
be in the next calendar month, then the last day of such Floating Lease Period
shall be the immediately preceding LIBOR Banking Day. The Floating Lease Period
for Alternate Rate based Floating Lease Payments shall commence on such Floating
Payment Date and shall end on the date specified for such in Lessee's notice of
election, provided such date shall not be more than ninety (90) days from such
Floating Payment Date. Lessee shall not make an election that would cause the
new Floating Payment Date resulting from such election to be later than the
Scheduled Termination Date. If Lessee fails to provide such notice of election
at least three (3) LIBOR Banking Days before any Floating Payment Date, Lessee
shall be deemed to have elected a one-month LIBOR based Applicable Equity Rate
and Applicable Tranche B Rate. At any time while a Lease Event of Default
exists, the Floating Payment Period shall be based on one-month LIBOR.

                  6. Default Purchase Options and Cure Rights.

                  6.1. Right to Cure Certain Lease Events of Default.

                  (a) If Lessee shall fail to make any Lease Payment when the
same shall have become due, and if such failure of Lessee to make such Lease
Payment shall not constitute the third consecutive such failure, then Lessor,
any Tranche B Lender or Tranche B Lenders (the "Curing Party") may (but is not
obligated to) pay to Collateral Agent for the benefit of Secured Parties, at any
time prior to the earlier of the expiration of ten (10) Business Days after the
Curing Party shall have received notice from Administrative Agent of the failure
of Lessee to make such Lease Payment, an amount equal to the Lease Payment or
Lease Payments then due by reason of the failure of Lessee to pay such Lease
Payment (otherwise than by declaration of acceleration) on such

                                      -23-
<PAGE>

Payment Date, and such payment by the Curing Party shall be deemed to have cured
any Loan Event of Default which arose or would have arisen from such failure of
Lessee.

                  (b) If Lessee shall fail to make any Supplemental Payment when
the same shall become due, or otherwise fail to perform any of its obligations
(other than the payment of a Lease Payment under the Lease Agreement) under any
Operative Document to which it is a party, which failure shall continue until
such time as such failure shall constitute a Lease Event of Default upon notice
to Lessee and can be cured by the payment of money, then a Curing Party may (but
is not obligated to) make such payment or perform such obligation through the
payment of money at any time prior to the expiration of ten (10) Business Days
after such Curing Party shall have received notice of the occurrence of any such
failure, and such payment or performance by such Curing Party shall be deemed to
have cured any Loan Event of Default which arose or would have arisen from such
failure of Lessee.

                  (c) Upon such payment or performance by a Curing Party, such
Curing Party shall (to the extent of such payment made by it and the costs and
expenses incurred in connection with such payments and performance thereof
together with interest thereon) be subrogated to the rights of Lessor and
Secured Parties to receive from Lessee the Lease Payment or Supplemental
Payment, as the case may be, paid by such Curing Party. If Collateral Agent
shall thereafter receive from Lessee such Lease Payment or Supplemental Payment,
Collateral Agent shall forthwith remit such payment to such Curing Party in
reimbursement for the funds so advanced by it.

                  (d) Until the expiration of the period during which the Curing
Party shall be entitled to exercise rights under Section 6.1(a) or (b) with
respect to any failure by Lessee referred to therein, neither Administrative
Agent, Collateral Agent, Indenture Trustee nor any Secured Party shall take or
commence any action it would otherwise be entitled to take or commence under the
Operative Documents as a result of such failure by Lessee.

                  6.2. Lessee Cure Right. Notwithstanding anything to the
contrary contained in this Agreement or any of the other Operative Documents,
each of Lessor, Indenture Trustee, each Tranche B Lender, Administrative Agent
and Collateral Agent hereby agrees with and for the benefit of Lessee as
follows:

                  (a) Lessee shall have the right to satisfy any conditions
precedent set forth in Section 3.2 in the event that Lessor fails to do so on a
timely basis, to the extent such condition precedent may be satisfied by a party
other than Lessor and to the extent it may be satisfied without violating any
law, court order or contractual obligation applicable thereto.

                  (b) Lessee shall have the right, in place of Lessor, to cure
within the grace periods provided therefor, to the extent capable of cure by a
party other than Lessor, any Loan Default or Loan Event of Default.

                  (c) Copies of all notices from Indenture Trustee, any Secured
Party, Administrative Agent or Collateral Agent to Lessor hereunder or under the
Indenture or Tranche B Loan Agreement shall be sent to Lessee by the sending
party and no such notice shall be effective for any purpose hereunder or
thereunder unless sent to Lessee.

                                      -24-
<PAGE>

                  (d) Lessor will, promptly upon becoming aware of any Loan
Default or Loan Event of Default, other than a Loan Default or Loan Event of
Default arising from a Lease Default or Lease Event of Default, notify Lessee of
the occurrence of such Loan Default or Loan Event of Default.

                  (e) Each payment by Lessee or Guarantor to Collateral Agent
under the Operative Documents shall be deemed to constitute a payment to
Indenture Trustee, any Tranche A Noteholder, any Tranche B Lender,
Administrative Agent or Collateral Agent, as the case may be, of the
corresponding payment obligation owing by Lessor to such Indenture Trustee,
Tranche A Noteholder, Tranche B Lender, Administrative Agent or Collateral Agent
under any of the Operative Documents solely for the purpose of determining
amounts owed by Lessee under the Operative Documents.

                  7. Security.

                  7.1. Security Interest. For valuable consideration, and to
secure the due payment and performance of all principal of, premium, if any, and
interest on the Tranche A Notes and the Tranche B Loans, Premium, Makewhole, and
Breakage Costs, if any, and all indebtedness and other liabilities and
obligations, whether now existing or hereafter arising (including any
obligations to indemnify, reimburse or pay costs and/or expenses) of Lessor to
Indenture Trustee, any Secured Party, Administrative Agent or Collateral Agent
arising out of or in any way connected with the Operative Documents and all
instruments, agreements and documents executed, issued and delivered pursuant
thereto (collectively, the "Secured Obligations"), Lessor hereby assigns,
conveys, mortgages, pledges, hypothecates, transfers and sets over to Collateral
Agent, and grants to Collateral Agent, for the benefit of the Secured Parties, a
first Lien on and security interest in the rights, title and interest of Lessor
now held or hereafter acquired in and to the following, except for Excepted
Payments and Excepted Rights with respect thereto (collectively, along with all
other rights, titles and interest pledged by Lessor to Collateral Agent pursuant
to any Security Supplements, the "Lessor Collateral"):

                  (a) the Items of Equipment;

                  (b) all Subleases pertaining to the Items of Equipment;

                  (c) any Bill of Sale and all warranties (including, without
         limitation, warranties of title, merchantability, fitness for a
         particular purpose, quality and freedom from defects) and rights of
         recourse against manufacturers, assemblers, sellers and others in
         connection with the Items of Equipment;

                  (d) the Security Documents, all Accrued Interest Premium, all

rights of any nature whatsoever arising out of or in connection with this
Agreement, the Lease Agreement or the Items of Equipment, including, without
limitation, Lease

                                      -25-

<PAGE>
         Payments, Supplemental Payments and Lessee Collateral and any other
         payments due and to become due under this Agreement, the Lease
         Agreement and the Subleases whether as repayments, reimbursements,
         contractual obligations, indemnities, damages or otherwise;

                  (f) all moneys now or hereafter paid or required to be paid to
         Indenture Trustee or any Secured Party pursuant to any Operative
         Document;

                  (g) all proceeds of Lessor Collateral including, without
         limitation, all rentals, income and profits in respect of the Items of
         Equipment, whether under the Lease Agreement or otherwise, all credits
         granted by any manufacturer or vendor with respect to the return of any
         Item of Equipment and the proceeds of any insurance payable with
         respect to the Items of Equipment;

                  (h) all claims, rights, powers, or privileges and remedies of
         Lessor under this Agreement and the Lease Agreement;

                  (i) all rights of Lessor under this Agreement and the Lease
         Agreement to make determinations to exercise any election (including,
         but not limited to, election of remedies) or option or to give or
         receive any notice, consent, waiver or approval, together with full
         power and authority to demand, receive, enforce, collect or receipt for
         any of the foregoing or any property which is the subject of this
         Agreement or the Lease Agreement, to enforce or execute any checks, or
         other instruments or orders, to file any claims and to take any action
         which (in the opinion of Collateral Agent) may be necessary or
         advisable in connection with any of the foregoing; and

                  (j) all moneys and investments held by Lessor as security
         under Section 28.4.4 of the Lease Agreement.

provided, however, Collateral Agent agrees for the benefit of Lessor that so
long as no Loan Event of Default has occurred and is continuing, it will not
exercise any of the rights assigned to it under clauses (h) and (i) of this
Section 7, other than the right to receive amounts due under the Lease Agreement
and Section 9 of this Agreement, without the prior written consent of Lessor and
Administrative Agent.

                  7.2. Further Assurances. For each Item of Equipment, Lessor
will, at Lessee's expense, make, execute, endorse, acknowledge, file and/or
deliver to Collateral Agent from time to time such confirmatory assignments,
conveyances, financing and continuation statements, transfer endorsements and
other assurances or instruments other than estoppel certificates or other
agreements, certificates and other documents to be delivered by any Sublessee or
other Person (other than an Affiliate of Lessee) which Administrative Agent may
reasonably request to perfect, preserve or protect Collateral Agent's security
interest granted hereunder. To the extent permitted by Applicable Law, Lessor
authorizes Collateral Agent to file any such financing and continuation
statements without the signature of Lessor and Lessor will pay all applicable
filing fees and related expenses. Lessor will, at Lessee's expense and upon the
request of Administrative Agent, qualify with the Texas Secretary of State to do
business in the State of Texas as a foreign limited partnership.

                                      -26-
<PAGE>

                  7.3. Termination. Upon the full and final discharge and
satisfaction of Lessor's obligations with respect to (i) all amounts owed under
the Operative Documents, (ii) all amounts owed under Sections 2.5.1 and 2.5.2 of
the Tranche B Loan Agreement and Article 3 or Sections 4.13, 4.14 or 7.01 of the
Indenture in relation to the purchase by Lessee of any Item of Equipment and
(iii) any Item of Equipment replaced in accordance with Section 13 of the Lease
Agreement, unless in the case of clause (ii) or (iii) a Lease Event of Default
shall have occurred and be continuing, the provisions of this Section 7 and each
Security Supplement shall terminate with respect to all Lessor Collateral or
such Items of Equipment (as applicable) and all right, title and interest of
Collateral Agent in and to all Lessor Collateral or such Items of Equipment (as
applicable) and the proceeds thereof shall revert to Lessor. Following payment
or substitution in accordance with the foregoing sentence, Lessor's obligations
to Indenture Trustee, Secured Parties, Administrative Agent and Collateral Agent
in and to all Items of Equipment or such Items of Equipment (as applicable)
shall terminate. Upon the occurrence and during the continuation of a Lease
Event of Default, the foregoing discharge shall be made only following
satisfaction of all of Lessee's obligations to purchase the Items of Equipment
under Section 24(d) of the Lease Agreement. Collateral Agent shall, at Lessor's
expense, execute and deliver any evidence of such release as Lessor may
reasonably require and furnish to Collateral Agent.

                  7.4. Other Security. To the extent that the obligations of
Lessor under any Operative Document are now or hereafter secured by property
other than Lessor Collateral or by the guarantee, endorsement or property of any
other Person, then at the written request of Administrative Agent, and in
accordance with its written instructions, Collateral Agent shall have the right
to pursue, relinquish, subordinate, modify or take any other action with respect
thereto, without in any way modifying or affecting any of Collateral Agent's
rights and remedies hereunder.

                  7.5. Power of Attorney. Lessor irrevocably authorizes
Collateral Agent and does hereby make, constitute and appoint Collateral Agent
and any officer of Collateral Agent, with full power of substitution, as
Lessor's true and lawful attorney-in-fact, with power, in its own name or in the
name of Lessor, to endorse any notes, checks, drafts, money orders, or other
instruments of payment (including payments payable under or in respect of any
policy of insurance) in respect of Lessor Collateral that may come into
possession of Collateral Agent; to sign and endorse any invoice, freight or
express bill, bill of lading, storage or warehouse receipts, drafts against
debtors, assignments, verifications and notices in connection with accounts, and
other documents relating to Lessor Collateral; to pay or discharge Taxes, Liens,
security interests or other encumbrances at any time levied or placed on or
threatened against Lessor Collateral; to demand, collect, receipt for,
compromise, settle and sue for monies due in respect of Lessor Collateral; and
generally, to do, at Collateral Agent's option and at Lessor's expense, at any
time, or from time to time, all acts and things which Collateral Agent deems
necessary to protect, preserve and realize upon Lessor Collateral and Collateral
Agent's security interests therein and in order to effect the intent of the
Operative Documents all as fully and effectually as Lessor might or could do;
and Lessor hereby ratifies all that said attorney shall lawfully do or cause to
be done by virtue hereof. This power of attorney shall be coupled with an
interest and irrevocable for the term of this Agreement and thereafter as long
as any of the obligations of Lessor under any Operative Document shall be
outstanding. The powers conferred on Collateral Agent hereunder are solely to
protect the security interest in Lessor Collateral and shall not impose any

                                      -27-
<PAGE>
duty upon Collateral Agent to exercise any such powers. Collateral Agent shall
be accountable only for amounts that it actually receives as a result of the
exercise of such powers and neither it nor any of its officers, directors or
employees shall be responsible to Lessor for any act or failure to act, except
for its own gross negligence or willful misconduct.

                  7.6. Assignment of Rights. Lessor agrees that the assignments
herein are irrevocable and it will not, while said assignments are in effect or
thereafter until Lessor has received from Administrative Agent notice of the
termination thereof, take any action as Lessor under the Lease Agreement or
otherwise which is inconsistent with this Agreement or make any other
assignment, designation or direction inconsistent herewith and that any
assignment, designation or direction inconsistent herewith shall be void. Lessor
and Collateral Agent agree that the following are, without limitation, rights,
powers, privileges, options, and benefits exclusively assigned by Lessor to
Collateral Agent (to the exclusion of Lessor) hereunder: (i) all of Lessor's
right to make claim for, receive, collect and receipt for (and to apply the same
to the payment of the principal of, Premium, Makewhole or Breakage Costs, if

Lessor Collateral or of any part thereof or of any interest therein at any sale
thereof, whether pursuant to foreclosure or power of sale or otherwise
hereunder, and may apply upon the transfer price the indebtedness secured hereby
owing to such transfer, to the extent of such transferee's distributive share of
the transfer price to the extent permitted by Applicable Law. Any such
transferee shall, upon any such transfer, acquire title to the properties so
transferred, free of the Lien of this Agreement.

interest.

                  7.9. Distribution of Moneys. Except as may be otherwise
provided in this Section 7 and for so long as no Loan Event of Default or Loan
Default resulting from any failure to make a payment under the Indenture or
Tranche B Loan has occurred and is continuing, all moneys received by Collateral
Agent shall be applied in accordance with this Section 7.9:

         and

                  Fifth, the balance, if any, of such payment remaining

                  (b) Prepayments. Moneys received by Collateral Agent
constituting payment of Acquisition Cost with respect to any Early Purchase

received by Collateral Agent:

                  First, to Indenture Trustee for the benefit of Tranche A
         Noteholders and to each Tranche B Lender for all principal, interest,
         Premium, Makewhole and Breakage Costs, if any, then due such Person in
         each case on a pari passu basis, provided however, if the amount
         received under Section 28.4.3 of the Lease Agreement is less than the
         Equity Redemption Target or the Net Proceeds Redemption Target, as the
         case may be, then the amounts to be paid to Tranche B Lenders hereunder
         shall be reduced by the amount of such shortfall.;

                  Second, for the benefit of Lessor, to each Limited Partner on
         a pari passu basis for all amounts then due under the Limited

         of each Item of Equipment so purchased; and

                  Third, to each other party hereto in accordance with clauses
         Second, Third and Fifth of Section 7.9(a).

                  (c) Payments after an End of Term Sale or Redelivery of
Equipment. All moneys received by Collateral Agent in accordance with Sections

                                      -29-
<PAGE>

                  First, to Indenture Trustee for the benefit of Tranche A
         Noteholders for principal and interest due on the Tranche A Notes;

                  Second, to Tranche B Lenders on a pari passu basis for
         principal and interest due on the Tranche B Loans; and

Second through Fifth of Section 7.9(a).

                  (d) Excepted Payments. Moneys received by Collateral Agent
constituting Excepted Payments shall be paid promptly after receipt thereof to
the Persons entitled thereto in accordance with the Operative Documents.

                  7.10. Payments after a Loan Event of Default. All payments
received and all amounts held or realized by Collateral Agent (including any
amounts realized by Collateral Agent from the exercise of any remedies) after
the occurrence and during the continuance of a Loan Event of Default or Loan
Default resulting from any failure to make a payment under the Indenture or
Tranche B Loan, and all payments or amounts then held or thereafter received by
Collateral Agent hereunder or under the Operative Documents other than Excepted
Payments, shall, so long as such Loan Event of Default continues and shall not
have been waived in writing by (i) Indenture Trustee, acting on behalf of the
Tranche A Noteholders, in the event of a Tranche A Event of Default that is not
also a Tranche B Event of Default, (ii) Majority Tranche B Lenders in the event
of a Tranche B Event of Default that is not also a Tranche A Event of Default or
(iii) Indenture Trustee, acting on behalf of the Tranche A Noteholders, and
Majority Tranche B Lenders for any Loan Event of Default that is both a Tranche
A Event of Default and a Tranche B Event of Default, be applied on the date
received:

                  First, so much of such payments or amounts held or realized by
         Collateral Agent as shall be required to reimburse Collateral Agent,
         Administrative Agent and Indenture Trustee for any expenses not
         reimbursed by Lessor in connection with the collection or distribution
         of such amounts held or realized by Collateral Agent or in connection
         with the expenses incurred in enforcing its remedies hereunder and
         preserving Lessor Collateral including, without limitation, those
         expenses contemplated under Section 12.1 of this Agreement, shall be
         retained by Collateral Agent or paid to Administrative Agent or
         Indenture Trustee, as the case may be; and

                  Second, to each other party hereto in accordance with clauses
         First through Third of Section 7.9(a) with any amounts remaining to be
         held as security for Lessor's and Lessee's obligations under the
         Operative Documents for so long as any Event of Default has occurred
         and is continuing and thereafter clauses Fourth and Fifth of Section
         7.9(a).

                  7.11. Application of Certain Other Payments. Any payments
received by Indenture Trustee or any Secured Party for which provision as to the

                                      -30-
<PAGE>

                  7.12. Other Payments. Except as otherwise provided in Sections
7.9 and 7.10, (i) any payments received by Collateral Agent for which no
provision as to the application thereof is made in the Operative Documents, or
elsewhere in this Section 7, and (ii) all payments received and amounts realized
by Collateral Agent with respect to Lessor Collateral (including, without
limitation, all amounts realized upon the sale, release or other disposition of
Lessor Collateral upon foreclosure of this Agreement), to the extent received or
realized at any time after payment in full of the amounts then due the parties
hereto shall be paid to Lessor or its designee.

                  7.13. Retention of Amounts by Collateral Agent. If at the time
of receipt by Collateral Agent of any payment or amount which would otherwise be
distributable to Lessor, there shall have occurred and be continuing a Loan
Default or a Loan Event of Default, Collateral Agent shall not distribute any
such amount to Lessor or its designee and shall hold it as security for Lessor's
obligations to Secured Parties under the Operative Documents until such time as
there shall not be continuing such Loan Default or Loan Event of Default.

                  7.14.    Exercise of Remedies.

                           7.14.1. Rights in Collateral. If a Loan Event of
Default shall have occurred and be continuing, then and in every such case
Collateral Agent shall, upon written request by Administrative Agent or
Indenture Trustee, acting on behalf of the Tranche A Noteholders after a Tranche
A Event of Default, subject to Lessee's right of quiet enjoyment pursuant to
Section 2 of the Lease Agreement, exercise any or all of the rights and powers
and pursue any and all of the remedies pursuant to this Section 7.14, any and
all remedies under the other Security Documents, and any and all remedies
available to a secured party under the UCC or any other provision or law and, in
the event such Loan Event of Default is related to a Lease Event of Default,
subject to Lessee's rights to purchase the Items of Equipment pursuant to
Section 24 of the Lease Agreement, may take possession of all or any part of
Lessor Collateral and may exclude Lessor, and, subject to the terms of the Lease
Agreement, Lessee, any sublessee and all Persons claiming under any of them
wholly or partly therefrom; provided, however, Collateral Agent shall not sell
or re-lease the Equipment for a period of thirty (30) days after such Event of
Default during which time Lessor, Administrative Agent, Collateral Agent and any
Tranche B Lender may remarket the Equipment.

                           7.14.2. Delivery of Documents; Taking Possession of
Collateral. Upon the occurrence of a Loan Event of Default, at the request of
Administrative Agent, Lessor shall promptly execute and deliver to Collateral
Agent such instruments of title and other documents as Administrative Agent may
deem necessary or advisable to enable Collateral Agent or a representative
designated by Collateral Agent, at such time or times and place or places as
Collateral Agent may specify, to obtain possession of all or any part of Lessor
Collateral to whose possession Collateral Agent shall at the time be entitled
hereunder. If Lessor shall for any reason fail to execute and deliver such
instruments and documents after the request by Collateral Agent, Collateral
Agent may (i) obtain a judgment conferring on Collateral Agent the right to
immediate possession and requiring Lessor to execute and deliver such
instruments and documents to Collateral Agent, to the entry of which judgment
Lessor hereby specifically consents, and (ii) pursue all or part of such Lessor
Collateral wherever it may be found and may enter any of the premises of Lessee
or Lessor wherever such Lessor Collateral may be or is

                                      -31-
<PAGE>
purported to be and search for such Lessor Collateral and take possession of and
remove such Lessor Collateral. All expenses of obtaining such judgment or of
pursuing, searching for and taking such property shall, until paid, be secured
by the Lien of this Agreement.

                           7.14.4. Possession of Collateral. Subject to the
proviso in Section 7.14.1, upon taking of possession pursuant hereto and at the
written request of Administrative Agent, Collateral Agent or a representative
designated by Collateral Agent may, from time to time, at the expense of Lessee,
make all such expenditures for maintenance, insurance, repairs, replacements and
alterations to any of Lessor Collateral, as it may deem appropriate and
commercially reasonable. In such case, Collateral Agent or a representative of
Collateral Agent shall have the right (but not the obligation) to maintain, use,
operate, store, lease, control or manage Lessor Collateral and to carry on the
business and to exercise all rights and powers of Lessor relating to Lessor
Collateral, as Administrative Agent shall deem best, including the right to
enter into any and all such agreements with respect to the maintenance, use,
operation, storage, leasing, control, management or disposition of Lessor
Collateral or any part thereof as Administrative Agent may determine; and
Collateral Agent shall be entitled to collect and receive directly all tolls,
rents (including Lease Payments and Supplemental Payments), revenues, issues,
income, products and profits of Lessor Collateral and every part thereof,
without prejudice, however, to the right of Secured Parties or Collateral Agent
under any provision of this Agreement to collect and receive all cash held by,
or required to be deposited with, Lessor hereunder. Such tolls, rents (including
Lease Payments and Supplemental Payments), revenues, issues, income, products
and profits shall be applied to pay the expenses of the use, operation, storage,
leasing, control, management or disposition of Lessor Collateral and of
conducting the business thereof, and of all maintenance, repairs, replacements,
alterations, additions and improvements, and to make all payments which
Collateral Agent may be required or may elect to make, if any, for Taxes,
assessments, insurance or other proper charges upon Lessor Collateral or any
part thereof (including the employment of engineers and accountants to examine,
inspect and make reports upon the properties and books and records of Lessor or
Lessee), and all other payments which Collateral Agent may be required or
authorized to make under any provision of this Agreement, as well as just and
reasonable compensation for the services of Collateral Agent, and of all Persons
properly engaged and employed by Collateral Agent.

                           7.14.5. Sale of Collateral. Subject to the proviso in
Section 7.14.1, in addition, Collateral Agent may, in accordance with the
written instructions of Administrative Agent and, if any such transaction or
related series of transactions relates to Equipment with value in excess of
$30,000,000, the Indenture Trustee, sell, assign, transfer and deliver the
whole, or from time to time to the extent permitted by law, any part of Lessor
Collateral or any interest therein, at any private sale or public auction with
or without demand, advertisement or notice (except as herein required or as may
be required by law) of the date, time and place of sale and any adjustment
thereof for cash or credit or other property for immediate or future delivery
and for such price or prices and on such terms as Administrative Agent may
determine, or as may be required by law. It is agreed that ten (10) Business
Days' notice to Lessor of the date, time and place (and terms, in the case of a
private sale) of any proposed sale by Collateral Agent of Lessor Collateral or
any part thereof or interest therein is reasonable. Each of Administrative
Agent, Collateral Agent and any Secured Party may be a purchaser of Lessor
Collateral or any part thereof or any interest therein at any sale thereof,
whether pursuant to foreclosure or power of

                                      -32-
<PAGE>
sale or otherwise. In accordance with the written instructions of Administrative
Agent, Collateral Agent may apply against the purchase price therefor all or
part of the amount then due under the Secured Obligations. Collateral Agent
shall, upon any such purchase, acquire good title to the property so purchased,
to the extent permitted by Applicable Law, free of all rights of redemption.

                           7.14.6. Discharge. Upon any sale of Lessor Collateral
or any part thereof or interest therein, whether pursuant to foreclosure or
power of sale or otherwise, the receipt of the purchase money by the official
making the sale by judicial proceeding or by Collateral Agent shall be
sufficient discharge to the purchaser for the purchase money and neither such
official nor such purchaser shall be obliged to see to the application thereof.

                           7.14.7. Appointment of Receiver. If a Loan Event of
Default shall have occurred and be continuing, Collateral Agent shall, as a
matter of right, be entitled to appoint a receiver or trustee or representative
(who may be Collateral Agent or any successor or nominee thereof, or any Tranche
B Lender appointed by Collateral Agent) for all or any part of Lessor
Collateral, whether such receivership or agency or representation be incidental
to a proposed sale of Lessor Collateral or the taking of possession thereof, the
exercise of remedies under this Agreement or the Lease Agreement or otherwise,
and Lessor hereby consents to the appointment of such a receiver, trustee or
representative. Any receiver, trustee or representative appointed for all or any
part of Lessor Collateral shall be entitled to exercise all rights of Collateral
Agent under this Agreement and the other Operative Documents to the extent
provided in such appointment and shall be entitled to exercise all the powers
and pursue all the remedies of Collateral Agent hereunder with respect to Lessor
Collateral.

                           7.14.8. Redemption. Any sale of Lessor Collateral or
any part thereof or any interest therein, whether pursuant to foreclosure or
power of sale or otherwise hereunder, shall forever be a perpetual bar against
Lessor, after the expiration of the period, if any, during which Lessor shall
have the benefit of redemption laws which may not be waived pursuant to Section
7.14.5 and this Section 7.14.8. Subject to the provisions of this Agreement,
Lessor covenants (to the extent that it may lawfully do so) that it will not at
any time insist upon, or plead, or in any manner whatsoever claim or take the
benefit or advantage of, any appraisement, valuation, stay or extension law
wherever enacted, nor at any time hereafter in force, in order to prevent or
hinder the enforcement of this Agreement or the execution of any power granted
herein to Secured Parties or Collateral Agent, or the absolute sale of Lessor
Collateral, or any part thereof, or the possession thereof by any transfer at
any sale under this Section 7.14; and Lessor for itself and all who may claim
under it, so far as it or any of them now or thereafter lawfully do so, waives
all right to have Lessor Collateral marshaled upon any foreclosure hereof, and
agrees that any court having jurisdiction to foreclose this Agreement may order
the sale of Lessor Collateral as an entirety.

                           7.14.9. Rights Cumulative; No Waiver. Each and every
right, power and remedy herein given to Secured Parties, Administrative Agent
and Collateral Agent specifically or otherwise in this Agreement shall be
cumulative and shall be in addition to every other right, power and remedy
herein specifically given or now or hereafter existing at law, in equity or by
statute, and each and every right, power and remedy whether specifically herein
given or

                                      -33-
<PAGE>
otherwise existing may be exercised from time to time and as often and in such
order as may be deemed expedient by Administrative Agent or Collateral Agent,
and the exercise or the beginning of the exercise of any power or remedy shall
not be construed to be a waiver of the right to exercise at the same time or
thereafter any other right, power or remedy. No delay or omission by Indenture
Trustee, any Secured Party, Administrative Agent or Collateral Agent in the
exercise of any right, remedy or power or in the pursuance of any remedy shall
impair any such right, power or remedy or be construed to be a waiver of any
default on the part of Lessor, Lessee or Guarantor or to be an acquiescence
therein.

                           7.14.10. Termination of Proceedings. If
Administrative Agent, Indenture Trustee, Secured Parties or Collateral Agent
shall have instituted any proceeding to enforce any right, power or remedy under
this Agreement by foreclosure, entry or otherwise, and such proceedings shall
have been discontinued or abandoned for any reason or shall have been determined
adversely to Administrative Agent, Indenture Trustee, Secured Parties or
Collateral Agent, then and in every such case Lessor, Administrative Agent,
Indenture Trustee, Secured Parties, Collateral Agent, Lessee and Guarantor
shall, subject to any binding determination in such proceeding, be restored to
their former positions and rights hereunder with respect to Lessor Collateral,
and all rights, remedies and powers of Administrative Agent, Indenture Trustee,
Secured Parties and Collateral Agent shall continue as if no such proceedings
had been instituted.

                  7.15. No Commingling of Funds. If at any time during a Loan
Default or Loan Event of Default Lessor should receive any amounts payable by
Lessee under the Lease Agreement or by Guarantor under the Participation
Agreement other than Excepted Payments, or any other proceeds for or with
respect to Lessor Collateral, it will hold such amounts in trust for Collateral
Agent and not commingle such amounts with any other amounts belonging to or held
by Borrower, advise Collateral Agent of such receipt and promptly forward such
amounts directly to Collateral Agent.

                  7.16. Lessor Collateral. Upon the occurrence and continuance
of any Loan Event of Default, Lessor will immediately upon receipt of all
checks, drafts, cash or other remittances in payment of any of its accounts,
contract rights or general intangible constituting part of Lessor Collateral, or
in payment for any Lessor Collateral sold, transferred, leased or otherwise
disposed of, or in payment or on account of its accounts, contracts, contract
rights, notes, drafts, acceptances, general intangibles, choses in action and
all other forms of obligation relating to any of Lessor Collateral so sold,
transferred or otherwise disposed of, deliver any such items to Collateral Agent
accompanied by a remittance report in form supplied or approved by Collateral
Agent, such items to be delivered to Collateral Agent in the same form received,
endorsed or otherwise assigned by Lessor where necessary to permit collection of
items and, regardless of the form of such endorsement, Lessor hereby waives
presentment, demand, notice of dishonor, protest and notice of protest.

                  7.17. Conflicts. If any provision of this Section 7 conflicts
with any provision contained in any other Operative Document, such provision
contained in this Section 7 shall prevail.

                  8.       Guaranty.

                  For the benefit of each Person to whom the Lessee owes any
payment or other obligation under the Operative Documents (each a "Guaranty
Party"), Guarantor irrevocably and unconditionally guarantees the full and
prompt payment when due (whether by acceleration or otherwise) of Lease
Payments, Supplemental Payments and any interest due thereon and of all
obligations and liabilities (including, without limitation, indemnities, fees
and interest thereon) of Lessee now existing or hereafter incurred under,
arising out of or in connection with this Agreement or any other Operative
Document and the due performance and compliance by Lessee with the terms of the
Lease Agreement and the Operative Documents binding on Lessee (all such
payments, interest, obligations and liabilities, collectively, the "Guaranteed
Obligations"). All payments by Guarantor under this guaranty shall be made on
the same basis as payments by Lessee under the Operative Documents. Guarantor
hereby waives notice of acceptance of this guaranty and notice of any liability
to which it may apply, and waives presentment, demand of payment, protest,
notice of dishonor or nonpayment of any such liability, suit or taking of other
action by an Guaranty Party against, and any other notice to, any party liable
thereon (including such Guarantor or any other guarantor). Any Guaranty Party
may at any time and from time to time unless otherwise prohibited under the
Operative Documents without the consent of, or notice to Guarantor, without
incurring responsibility to Guarantor and without impairing or releasing the
obligations of Guarantor hereunder, upon or without any terms or conditions and
in whole or in part:

                  (a) change the manner, place or terms of payment of, and/or
change or extend the time of payment of, renew or alter, any of the Guaranteed
Obligations, any security therefor, or any liability incurred directly or
indirectly in respect therof, and the guaranty herein made shall apply to the
Guaranteed Obligations as so changed, extended, renewed or altered;

                  (b) sell, exchange, release, surrender, realize upon or
otherwise deal with in any manner and in any order any property by whomsoever at
any time pledged or mortgaged to secure, or howsoever securing, the Guaranteed
Obligations or any liability is (including any of those hereunder) incurred
directly or indirectly in respect thereof or hereof, and/or any offset there
against;

                  (c) exercise or refrain from exercising any rights against
Lessee or others or otherwise act or refrain from acting;

                  (d) settle or compromise any of the Guaranteed Obligations,
any security therefor or any liability (including any of those hereunder)
incurred directly or indirectly in respect thereof or hereof;

                  (e) apply any sums by whomsoever paid or howsoever realized to
any liability or liabilities of Lessee to any Guaranty Party regardless of what
liabilities or liabilities of Lessee remain unpaid; and/or

                                      -35-
<PAGE>

                  (f) consent to or waive any breach of, or any act, omission or
default under, any of the Operative Documents or otherwise amend, modify or
supplement any of the Operative Documents or any of such other instruments or
agreements.
                  The obligations of Guarantor under this Section 8 are absolute
and unconditional and shall remain in full force and effect without regard to,
and shall not be released, suspended, discharged, terminated or otherwise
affected by, any circumstance or ocurrence whatsoever, including,without
limitation (i) any action or inaction by any Guaranty Party; or (ii) any
invalidity, irregularity or unenforceability of all or part of the Guaranteed
Obligations or of any security therefor. The obligations under this Section 8
are primary obligations of Guarantor. If and to the extent that Guarantor makes
any payment to any Guaranty Party or to any other Person pursuant to or in
respect of this Section 8, any claim which Guarantor may have against Lessee by
reason thereof shall be subject and subordinate to the prior payment in full of
the Guaranteed Obligations.

                  The obligations under this Section 8 are continuing and all
liabilities to which they apply or may apply under the terms hereof shall be
conclusively presumed to have been created in reliance hereon. No failure or
delay on the part of any Guaranty Party in exercising any right, power or
privilege hereunder and no course of dealing between Guarantor, any Guaranty
Party or the holder of any Tranche A Note or Tranche B Note shall operate as a
waiver thereof; nor shall any single or partial exercise of any right, power or
privilege hereunder preclude any other or further exercise thereof or the
exercise of any other right, power or privilege. The rights, powers and remedies
herein expressly provided are cumulative and not exclusive of any rights, powers
and remedies which any Guaranty Party would otherwise have. No notice to or
demand on Guarantor in any case shall entitle Guarantor to any other further
notice or demand in similar or other circumstances or constitute a waiver of the
rights of any Guaranty Party to any other or further action in any circumstances
without notice or demand.

                  This guaranty shall continue to be effective, or be
reinstated, as the case may be, if at any time payment, or any part thereof, or
of any of the Guaranteed Obligations is rescinded or must otherwise be restored
or returned by the Guaranty Parties upon the insolvency, bankruptcy,
dissolution, liquidation or reorganization of Lessee or Guarantor, or upon or as
a result of the appointment of a receiver, intervenor, or conservator of, or
trustee or similar officer for, Lessee or Guarantor or any substantial part of
its property, all as though such payment had not been made and any statute of
limitations in favor of Guarantor against any Guaranty Party relating to any
such amount to be restored or returned shall be tolled, or deemed to have been
tolled, to the extent permitted by law, during the period from the date such
payment was made to such Guaranty Party until the date such Guaranty Party so
restores or returns such amount.

                  9.       Covenants.

                  9.1. Lessor and Lessor General Partner Covenants. Each of
Lessor and Lessor General Partner covenants for the benefit of each other party
hereto (unless each shall have otherwise waived in writing compliance herewith)
during the term of this Agreement as follows:

                                      -36-
<PAGE>

                  (a) It shall take all actions as are required to keep the
representations and warranties made by it in Section 2.4 (with respect to
Lessor) and in Section 2.5 (with respect to Lessor General Partner) (except, in
the case of clause (b) of Section 2.4 (with respect to Lessor), if the location
of such office shall change, it shall provide each other party hereto with not
less than ten (10) days' prior written notice of such change), true and correct
in all material respects (but without regard to the date when such
representations and warranties were made or are expressed to be effective) until
such time as all of the obligations secured hereby have been paid in full.

                  (b) The proceeds of each Tranche A Note and Tranche B Loan
shall be used solely to finance Lessor's acquisitions of Items of Equipment in
accordance with the terms of this Agreement and for costs related to such
transactions. No part of the proceeds of any Tranche A Note or Tranche B Loan
will be used to purchase or carry any Margin Stock or to extend credit for the
purpose of purchasing or carrying any Margin Stock. Neither the issuing of any
Tranche A Note, the making of any Tranche B Loan nor the use of the proceeds
thereof will violate or be inconsistent with the provisions of Regulation T, U
or X of the Board of Governors of the Federal Reserve System.

                  (c) It shall comply in all material respects with all
Applicable Laws, rules, regulations and orders of any jurisdiction, such
compliance to include paying when due all Taxes imposed upon it or upon its
property by any Governmental Entity except to the extent contested in good faith
and for which adequate reserves have been segregated.

                  (d) It shall promptly take, and maintain the effectiveness of,
all action of the type referred to in clause (b) of Section 2.3 or otherwise
that may, from time to time, be necessary or appropriate under Applicable Law in
connection with the performance by Lessor of its obligations under the Operative
Documents, or the taking of any action hereby or thereby contemplated, or
necessary for the legality, validity, binding effect or enforceability of the
Operative Documents, or for the making of any payment or the transfer or
remittance of any funds by Lessor under the Operative Documents.

                  (e) It shall duly pay and discharge (i) immediately upon the
attachment thereof (A) in the case of Lessor General Partner, all Liens
attributable to Lessor General Partner (other than Permitted Liens) on any
Lessor Collateral, and (B) in the case of Lessor, all Liens other than Permitted
Liens on any Lessor Collateral, (ii) as and when due, all of its indebtedness
and other obligations before the time that any Lien attaches unless and only to
the extent that any such amounts are not yet due and payable or the validity
thereof is being contested in good faith by appropriate proceedings so long as
such proceedings do not involve any material danger of the sale, forfeiture or
loss of the Items of Equipment or any interest therein and Lessor maintains
appropriate reserves with respect thereto or has made adequate provision for the
payment thereof, in accordance with generally accepted accounting principles and
approved by Administrative Agent and (iii) all Taxes imposed upon or against it
or its property or assets, or upon any property leased by it, prior to the date
on which penalties attach thereto.

                  (f) It shall keep at all times books of record and account in
which full, true and correct entries will be made of all dealings or
transactions in relation to its business and

                                      -37-
<PAGE>
affairs, and provide or cause to be provided adequate protection against loss or
damage to such books of record and account.

                  (g) It shall not operate in a manner that would result in an
actual, constructive or substantive consolidation with Limited Partners or any
other Person other than Lessee or Lessor General Partner in the case of Lessor
or other than Lessee or Lessor in the case of Lessor General Partner, and in
such connection Lessor shall observe all limited partnership formalities,
maintain records separately and independently from those of Limited Partners or
other Person and enter into any transactions with Limited Partners only on an
arm's-length contractual basis.

                  (h) It shall not, and shall cause Co-Obligor not to, without
the consent of Indenture Trustee acting on behalf of Majority Tranche A
Noteholders, the consent of all Tranche B Lenders and the consent of
Administrative Agent (i) enter into any business other than its acquisition,
leasing, financing and sale of the Equipment, (ii) create, incur, assume or
permit to exist any Indebtedness, except as expressly permitted by this
Agreement, (iii) enter into, or be a party to, any transaction with any Person,
except the transactions set forth in the Operative Documents and as expressly
permitted thereby, (iv) acquire any assets other than the Equipment and the
rights of Lessor set forth under the Operative Documents, or (v) make any
investment in, guarantee the obligations of, or make or advance money to any
Person (other than capital contributions to Co-Obligor for the sole purpose of
maintaining Co-Obligor's corporate existence), through the direct or indirect
lending of money, holding of securities or otherwise except the transactions set
forth in the Operative Documents and as expressly permitted thereby.

                  (i) It shall not wind up, liquidate or dissolve its affairs or
enter into any transaction of merger or consolidation, or convey, sell, lease
(substantially as a whole), or otherwise dispose of (whether in one or in a
series of transactions) its assets except as expressly permitted by this
Agreement.

                  (j) It shall notify Lessee of any Loan Event of Default except
any such Loan Event of Default caused by or related to a Lease Event of Default.

                  (k) It shall not claim ownership of any Item of Equipment on
any federal, state, local or foreign tax return or filing.

                  9.2. Lessee Covenants for the Benefit of Indenture Trustee and
Tranche A Noteholders. Lessee covenants and agrees solely for the benefit of
Lessor, Co-Obligor, Indenture Trustee and each Tranche A Noteholder (unless
Indenture Trustee or Majority Tranche A Noteholders shall otherwise waive in
writing compliance herewith or the Tranche A Notes shall have been defeased
pursuant to and in accordance with the terms of Article 7 of the Indenture) that
on the Closing Date and thereafter during the remaining term of this Agreement
as follows:

                  (a) Limitation on Incurrence of Additional Indebtedness.
Lessee will not, and will not permit any of its Restricted Subsidiaries to,
directly or indirectly, create, incur, assume, guarantee, become liable,
contingently or otherwise, with respect to, or otherwise become responsible for
payment of (collectively, "incur") any Indebtedness (other than Permitted
Indebtedness); provided, however, that if no Tranche A Event of Default shall
have occurred and

                                      -38-
<PAGE>
be continuing at the time of or as a consequence of the incurrence of any such
Indebtedness, Lessee and its Restricted Subsidiaries may incur Indebtedness
(including, without limitation, Acquired Indebtedness) if on the date of the
incurrence of such Indebtedness, after giving effect to the incurrence thereof,
the Consolidated Fixed Charge Coverage Ratio of Lessee is greater than 2.25 to
1.0.

                  For purposes of determining compliance with this covenant, (i)
in the event that an item of Indebtedness meets the criteria of more than one of
the types of Indebtedness permitted by this covenant, Lessee in its sole
discretion will classify such item of Indebtedness and will only be required to
include the amount and type of each class of Indebtedness in the test specified
in the first paragraph of this covenant or in one of the clauses of the
definition of the term "Permitted Indebtedness", (ii) the amount of Indebtedness
(other than Indebtedness consisting of an Operating Lease Facility) issued at a
price which is less than the principal amount thereof shall be equal to the
amount of liability in respect thereof determined in accordance with GAAP, (iii)
Indebtedness incurred in connection with, or in contemplation of, any
transaction described in the definition of the term "Acquired Indebtedness"
shall be deemed to have been incurred by Lessee or one of its Restricted
Subsidiaries, as the case may be, at the time an acquired Person becomes such a
Restricted Subsidiary (or is merged into Lessee or such a Restricted Subsidiary)
or at the time of the acquisition of assets, as the case may be, (iv) the
maximum amount of Indebtedness that Lessee and its Restricted Subsidiaries may
incur pursuant to this covenant shall not be deemed to be exceeded, with respect
to any outstanding Indebtedness, due solely to the result of fluctuations in the
exchange rates of currencies, and (v) guarantees or Liens supporting
Indebtedness permitted to be incurred under this covenant may be issued or
granted if otherwise issued or granted in accordance with the terms of this
Section 9.2.

                  (b) Limitation on Restricted Payments. Lessee will not, and
will not cause or permit any of its Restricted Subsidiaries to, directly or
indirectly, (i) declare or pay any dividend or make any distribution (other than
dividends or distributions payable in Qualified Capital Stock of Lessee or in
options, warrants, or other rights to purchase such Qualified Capital Stock (but
excluding any debt security or Disqualified Capital Stock convertible into, or
exchangeable for, such Qualified Capital Stock)) on or in respect of shares of
Lessee's Capital Stock to holders of such Capital Stock, (ii) purchase, redeem
or otherwise acquire or retire for value any Capital Stock of Lessee or any
warrants, rights or options to purchase or acquire shares of any class of such
Capital Stock (in each case, other than in exchange for Qualified Capital Stock
of Lessee or options, warrants or other rights to purchase such Qualified
Capital Stock (but excluding any debt security, or Disqualified Capital Stock
convertible into, or exchangeable for, such Qualified Capital Stock)), (iii)
make any principal payment on, purchase, defease, redeem, prepay, decrease or
otherwise acquire or retire for value, prior to any scheduled final maturity,
scheduled repayment or scheduled sinking fund payment, any Indebtedness of
Lessee that is subordinate or junior in right of payment to Lessee's rental
payment obligations under the Lease Agreement or (iv) make any Investment (other
than Permitted Investments) (each of the foregoing actions set forth in clauses
(i), (ii), (iii) and (iv) being referred to as a "Restricted Payment"), if at
the time of such Restricted Payment or immediately after giving effect thereto,
(A) a Tranche A Default or a Tranche A Event of Default shall have occurred and
be continuing or (B) Lessee is not able to incur at least $1.00 of additional
Indebtedness (other than Permitted Indebtedness) in compliance with Section
9.2(a) or (C) the aggregate amount of Restricted Payments (including such
proposed

                                      -39-
<PAGE>
Restricted Payment) made subsequent to the Issue Date (the amount expended for
such purposes, if other than in cash, being the fair market value of such
property as determined reasonably and in good faith by the Board of Directors of
Lessee) shall exceed the sum of: (1) 50% of the cumulative Consolidated Net
Income (or if cumulative Consolidated Net Income shall be a loss, minus 100% of
such loss) of Lessee earned subsequent to the Issue Date and on or prior to the
date the Restricted Payment occurs (the "Reference Date") (treating such period
as a single accounting period); plus (2) 100% of (x) the aggregate net cash
proceeds and (y) the aggregate fair market value (as determined in good faith by
the Board of Directors of Lessee as evidenced by a Board Resolution), of
property other than cash, received by Lessee from any Person (other than a
Subsidiary of Lessee) from the issuance and sale subsequent to the Issue Date
and on or prior to the Reference Date of Qualified Capital Stock of Lessee or
options, warrants or other rights to purchase such Qualified Capital Stock (but
excluding any debt security or Disqualified Capital Stock convertible into, or
exchangeable for, such Qualified Capital Stock); plus (3) without duplication of
any amounts included in clause (C)(2) above, 100% of the aggregate net cash
proceeds of any equity contribution received by Lessee from a holder of Lessee's
Capital Stock (excluding, in the case of clauses (C)(3) and (4), any net cash
proceeds from an Equity Offering to the extent used to purchase Equipment in
accordance with Section 28.4.1 of the Lease Agreement and in compliance with
Section 3.03(b) of the Indenture; plus (4) 100% of the aggregate net cash
proceeds received by Lessee from any Person (other than a Subsidiary of Lessee)
from the issuance and sale (subsequent to the Issue Date) of debt securities or
shares of Disqualified Capital Stock that have been converted into or exchanged
for Qualified Capital Stock of Lessee, together with the aggregate cash received
by Lessee at the time of such conversion or exchange; plus (5) without
duplication, the sum of (a) the aggregate amount returned in cash to Lessee or a
Restricted Subsidiary of Lessee on or with respect to Investments (other than
Permitted Investments) made subsequent to the Issue Date whether through
interest payments, principal payments, dividends or other distributions or
payments, (b) the net cash proceeds received by Lessee or any of its Restricted
Subsidiaries from the disposition of all or any portion of such Investments
(other than to a Subsidiary of Lessee) and (c) upon redesignation of an
Unrestricted Subsidiary as a Restricted Subsidiary, the fair market value of
such Subsidiary; provided, however, that the sum of clauses (a), (b) and (c)
above shall not exceed the aggregate amount of all such Investments made
subsequent to the Issue Date; plus (6) $15,000,000.

                  Notwithstanding the foregoing, the provisions set forth in the
immediately preceding paragraph do not prohibit: (i) the payment of any dividend
within sixty (60) days after the date of declaration of such dividend if the
dividend would have been permitted on the date of declaration; (ii) the
acquisition of any shares of Capital Stock of Lessee, either (A) solely in
exchange for shares of Qualified Capital Stock of Lessee or options, warrants,
or other rights to purchase such Qualified Capital Stock (other than any debt
security or Disqualified Capital Stock convertible into, or exchangeable for,
such Qualified Capital Stock) or (B) through the application of net proceeds of
a substantially concurrent sale for cash (other than to a Subsidiary of Lessee)
of shares of Qualified Capital Stock of Lessee or options, warrants, or other
rights to purchase such Qualified Capital Stock (other than any debt security or
Disqualified Capital Stock convertible into, or exchangeable for, such Qualified
Capital Stock); (iii) the acquisition of any Indebtedness of Lessee that is
subordinate or junior in right of payment to Lessee's rental payment obligations
under the Lease Agreement either (A) solely in exchange for shares of

                                      -40-
<PAGE>
Qualified Capital Stock of Lessee, or options, warrants, or other rights to
purchase such qualified Capital Stock or (B) through the application of net
proceeds of a substantially concurrent sale for cash (other than to a Subsidiary
of Lessee) of (1) shares of Qualified Capital Stock of Lessee or (2) Refinancing
Indebtedness; (iv) dividends or payments to Guarantor of cash to be immediately
applied to repurchases by Guarantor of Qualified Capital Stock of Guarantor or
options to purchase such Qualified Capital Stock from directors or employees or
former directors or former employees of Guarantor or any of its Subsidiaries or
their authorized representatives upon the death, disability or termination of
employment of such persons or pursuant to the terms of any customary agreement
under which such Qualified Capital Stock or options were issued, in an aggregate
amount not to exceed $1,000,000 plus any life insurance proceeds in any calendar
year; (v) the repurchase of any Indebtedness which is subordinated to Lessee's
rental payment obligations under the Lease Agreement at a purchase price not
greater than 101% of the principal amount of such Indebtedness in the event of a
change of control in accordance with provisions similar to Section 9.2(i)
hereof; provided that, prior to or simultaneously with the purchase, the Lessor
has made the Change of Control Offer as provided in the Indenture with respect
to the Tranche A Notes and has repurchased all Tranche A Notes validly tendered
for payment in connection with such Change of Control Offer; (vi) payments or
distributions to dissenting stockholders pursuant to applicable law, pursuant to
or in connection with a consolidation, merger or transfer of assets that
complies with the provisions of Section 9.2 hereof applicable to mergers,
consolidating and transfers of all or substantially all of the property and
assets of Lessee, (vii) any dividends or payments to Guarantor in respect of
overhead expenses, legal, accounting, commissions reporting and other
professional fees and expenses of Guarantor that are directly attributable to
the operations of Lessee and its restricted subsidiaries; (viii) payments to
holders of Qualified Capital Stock of Lessee or Guarantor (A) in lieu of the
issuance of fractional shares of Qualified Capital Stock of Lessee or Guarantor
or (B) to redeem or repurchase stock purchase of similar rights issued as a
shareholder rights device; provided that the payments made pursuant to this
clause (viii) from the Issue Date through the final stated maturity of the
Tranche A Notes may not exceed $2,000,000; and (ix) repurchases, acquisitions or
retirements of shares of Qualified Capital Stock of Lessee or Guarantor deemed
to occur upon the exercise of stock options or similar rights issued under
employee benefits plans of Lessee or Guarantor if such shares represent all or a
portion of the exercise price or are surrendered in connection with satisfying
any income tax obligation; provided that, except in the case of clauses (i) and
(ii), no Tranche A Default or Tranche A Event of Default shall have occurred and
be continuing or occur as a consequence of the actions or payments set forth
therein. In determining the aggregate amount of Restricted Payments made
subsequent to the Issue Date in accordance with clause (C) of the immediately
preceding paragraph, amounts expended, without duplication, pursuant to clauses
(i), (ii)(B), (iv) through (vi) and (viii) shall be included in such
calculation.

                  Not later than ten (10) days after the date of making any
Restricted Payment (but not including any transaction described in the preceding
paragraph), Lessee shall deliver to Indenture Trustee an officers' certificate
stating that such Restricted Payment complies with Section 9.2 and setting forth
in reasonable detail the basis upon which the required calculations were
computed, which calculations may be based upon Lessee's latest available
internal quarterly financial statements.

                                      -41-
<PAGE>

                  (c) Limitation on Asset Sales. Lessee will not, and will not
permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless
(i) Lessee or the applicable Restricted Subsidiary, as the case may be, receives
consideration at the time of such Asset Sale at least equal to the fair market
value of the assets sold or otherwise disposed of (as determined in good faith
by Lessee's Board of Directors) and (ii) at least 75% of the consideration
received by Lessee or the Restricted Subsidiary, as the case may be, from such
Asset Sale shall be in the form of cash or Cash Equivalents; provided that (A)
the amount of any liabilities of Lessee or any such Restricted Subsidiary (other
than liabilities that are by their terms subordinated to Lessee's rental payment
obligations under the Lease Agreement) that are assumed by the transferee of any
such assets and (B) the fair market value of any marketable securities received
by Lessee or any such Restricted Subsidiary in exchange for any such assets that
are promptly converted into cash shall be deemed to be cash for purposes of this
provision; and provided, further, that in no event shall the aggregate fair
market value at the time of receipt of consideration received by Lessee in a
form other than cash or Cash Equivalents exceed 15% of Lessee's Consolidated
Total Assets. In the event of an Asset Sale, Lessee shall apply, or cause such
Restricted Subsidiary to apply, the Net Cash Proceeds relating to such Asset
Sale within 720 days of receipt thereof either (A) to repay or prepay any
indebtedness under the Credit Agreement, and effect a permanent reduction
thereof, (B) to make an investment in either (x) properties and assets that
replace the properties and assets that were the subject of such Asset Sale or
(y) properties or assets that will be used in the business of Lessee and its
Restricted Subsidiaries as existing on the Issue Date or in businesses similar
or reasonably related thereto or in the capital stock of any entity a majority
of whose assets consists of the properties or assets described under (x) or (y)
("Replacement Assets"), or (C) to a combination of prepayment and investment
permitted by the immediately foregoing clauses (A) and (B). After the day on
which the aggregate amount of Net Cash Proceeds which have not been applied as
permitted in the immediately foregoing clauses (A), (B) and (C) of the next
preceding sentence (a "Net Proceeds Offer Amount") exceeds $15,000,000 (the "Net
Proceeds Offer Trigger Date"), Lessee shall make an offer to apply such Net Cash
Proceeds to purchase Equipment from Lessor at the Acquisition Cost thereof;
provided, Lessee shall have the option of applying a portion of the Net Proceeds
Offer Amount to the repurchase of any Indebtedness not subordinated to its
rental payment obligations under the Lease Agreement, pro rata based on the
amount of Tranche A Notes, the Tranche B Loans and the Equity Contributions
outstanding on the one hand, and the amount of such other Indebtedness
outstanding on the other hand. The purchase price for such other Indebtedness
will not exceed 100% of the principal amount thereof, plus accrued and unpaid
interest thereon. If Lessee elects to so repay such other Indebtedness, the
amount of Equipment purchased by it will be reduced by the amount of such other
Indebtedness so repurchased.

                  If at any time any non-cash consideration received by Lessee
or any Restricted Subsidiary of Lessee, as the case may be, in connection with
any Asset Sale is converted into or sold or otherwise disposed of for cash
(other than interest received with respect to any such non-cash consideration),
then such conversion or disposition shall be deemed to constitute an Asset Sale
and the Net Cash Proceeds thereof shall be applied in accordance with this
covenant. To the extent that the aggregate principal amount of the Tranche A
Notes, the Tranche B Loans and the Equity Contributions repurchased is less than
the Net Proceeds Offer Amount, Lessee and its

                                      -42-
<PAGE>
Restricted Subsidiaries may use such deficiency for general corporate purposes.
Upon completion of such Net Proceeds Offer, the Net Proceeds Offer Amount will
be reset to zero.

                  Notwithstanding the two (2) immediately preceding paragraphs,
Lessee and its Restricted Subsidiaries will be permitted to consummate an Asset
Sale without complying with the foregoing paragraphs to the extent (i) at least
80% of the consideration for such Asset Sale constitutes Replacement Assets and
(ii) such Asset Sale is for fair market value; provided that any consideration
not constituting Replacement Assets received by Lessee or any of its Restricted
Subsidiaries in connection with any Asset Sale permitted to be consummated under
this paragraph shall constitute Net Cash Proceeds subject to the provisions of
the preceding paragraph.

                  If at any time any non-cash consideration received by Lessee
or any Restricted Subsidiary of Lessee, as the case may be, in connection with
any Asset Sale is converted into or sold or otherwise disposed of for cash
(other than interest received with respect to any such non-cash consideration),
then such conversion or disposition shall be deemed to constitute an Asset Sale
and the Net Cash Proceeds thereof shall be applied in accordance with this
covenant. To the extent that the aggregate principal amount of Tranche A Notes,
tendered pursuant to such Net Proceeds Offer is less than the net Proceeds Offer
Amount allocable to the Tranche A Notes, Lessee and its Restricted Subsidiaries
may use such deficiency for general corporate purposes.

                  (d) Limitation on Dividend and Other Payment Restrictions
Affecting Subsidiaries. Lessee will not, and will not cause or permit any of its
Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or
permit to exist or become effective any encumbrance or restriction on the
ability of any Restricted Subsidiary of Lessee to (i) pay dividends or make any
other distributions on or in respect of its Capital Stock; (ii) make loans or
advances or to pay any Indebtedness or other obligation owed to Lessee or any
other Restricted Subsidiary of Lessee; or (iii) transfer any of its property or
assets to Lessee or any other Restricted Subsidiary of Lessee, except for such
encumbrances or restrictions existing under or by reason of: (A) applicable law;
(B) a Securitized Operating Lease Facility; (C) the Credit Agreement; (D) any
agreement or instrument governing Acquired Indebtedness, which encumbrance or
restriction is not applicable to any Person, or the properties or assets of any
Person, other than the Person or the properties or assets of the Person so
acquired; (E) agreements existing on the Issue Date to the extent and in the
manner such encumbrances and restrictions are contemplated by such agreements;
(F) in the case of clause (iii) above: (1) agreements or instruments arising or
agreed to in the ordinary course of business that restrict in a customary manner
the subletting, assignment or transfer of any property or asset subject to a
lease, license, conveyance or other contract and (2) any transfer of, agreement
to transfer, option or right with respect to, or Lien on, any property or assets
of Lessee or any Restricted Subsidiary entered into in compliance with Section
9.2 hereof; (G) an agreement that has been entered into for the sale or
disposition of all or substantially all of the Capital Stock of, or property and
assets of, any Restricted Subsidiary of Lessee; (H) provisions in agreements or
instruments which prohibit the payment of dividends or the making of other
distributions with respect to any Capital Stock of a Person other than on a pro
rata basis; or (I) an agreement governing Indebtedness incurred to Refinance the
Indebtedness issued, assumed or incurred pursuant to an agreement referred to in
clause (B), (C), (D) or (E) above; provided, however, that the provisions
relating to

                                      -43-
<PAGE>
such encumbrance or restriction contained in any such Indebtedness are no less
favorable to Lessee or the relevant Restricted Subsidiary of Lessee in any
material respect as determined by the Board of Directors of Lessee in its
reasonable and good faith judgment than the provisions relating to such
encumbrance or restriction contained in agreements referred to in such clause
(B), (C), (D) or (E). Nothing contained in clause (iii) of this Section 9.2(d)
shall prevent Lessee or any of its Restricted Subsidiaries from creating,
incurring, assuming or suffering to exist any Lien created, incurred, assumed or
suffered to exist in accordance with the other terms of this Agreement.

                  (e) Limitation on Preferred Stock of Restricted Subsidiaries.
Lessee will not and will not permit any of its Restricted Subsidiaries to issue
any Preferred Stock (other than to Lessee or to a Wholly Owned Restricted
Subsidiary of Lessee) or permit any Person (other than Lessee or a Wholly Owned
Restricted Subsidiary of Lessee) to own any Preferred Stock of any Restricted
Subsidiary of Lessee; provided that the foregoing shall not prohibit (i) the
creation of a Lien in any such Preferred Stock under the Credit Agreement and
otherwise created in accordance with this Agreement or (ii) issuances of sales
to directors of directors' qualifying shares or issuances or sales to foreign
nationals of such Preferred Stock, in each case to the extent required by
applicable law.

                  (f) Limitation on Liens. Lessee will not, and will not cause
or permit any of its Restricted Subsidiaries to, directly or indirectly, create,
incur, assume or permit or suffer to exist any Liens of any kind against or upon
any property or assets of Lessee or any of its Restricted Subsidiaries whether
owned on the Issue Date or acquired after the Issue Date, or any proceeds
therefrom, or assign or otherwise convey any right to receive income or profits
therefrom except for (i) Liens existing as of the Issue Date (other than Liens
securing Indebtedness under the Credit Agreement) to the extent and in the
manner such Liens are in effect on the Issue Date and Liens to the extent
contemplated by the Operative Documents; (ii) Liens securing Indebtedness under
the Credit Agreement incurred pursuant to Section 9.2(a); (iii) Liens securing
an Operating Lease Facility, including Liens securing or relating to any
obligations with respect to such Operating Lease Facility or with respect to
guarantees provided to such Operating Lease Facilities; (iv) Liens of Lessee or
a Wholly Owned Restricted Subsidiary of Lessee on assets of any Restricted
Subsidiary of Lessee; (v) Liens securing Refinancing Indebtedness which is
incurred to Refinance any Indebtedness which has been secured by a Lien
permitted under this Agreement and which has been incurred in accordance with
the provisions of this Agreement; provided, however, that such Liens (1) are no
less favorable to the Tranche A Noteholders and are not more favorable to the
lienholders with respect to such Liens than the Liens in respect of the
Indebtedness being Refinanced and (2) do not extend to or cover any property or

unless: (i) either (A) Lessee shall be the surviving or continuing corporation

which Lessee is merged or the Person which acquires by sale, assignment,
transfer, lease, conveyance or other disposition the properties and assets of
Lessee and of Lessee's Restricted Subsidiaries substantially as an entirety (the

under the laws of the United States or any State thereof or the District of
Columbia and (2) shall expressly assume all obligations of Lessee under the
Lease Agreement on the part of Lessee to be performed or observed by Lessee;
(ii) immediately after giving effect to such transaction and the assumption
contemplated by clause (i)(B)(2) above (including giving effect to any
Indebtedness and Acquired Indebtedness incurred in connection with or in respect
of such transaction), Lessee or such Surviving Entity, as the case may be, (a)
shall have a Consolidated Net Worth equal to or greater than the Consolidated

                           (i) Lessee will not, and will not permit any of its
         Restricted Subsidiaries to, directly or indirectly, enter into or
         permit to exist any transaction or series of related transactions
         (including, without limitation, the purchase, sale, lease or exchange
         of any property or the rendering of any service) with, or for the
         benefit of, any of its Affiliates (each an "Affiliate Transaction"),
         other than (A) Affiliate Transactions permitted under paragraph (ii)
         below and (B) Affiliate Transactions on terms that are no less
         favorable than those that might reasonably have been obtained in a
         comparable transaction at such time on an arm's-length basis from a
         Person that is not an Affiliate of Lessee or such Restricted
         Subsidiary. All Affiliate Transactions (and each series of related
         Affiliate Transactions which are similar or part of a common plan)

         in excess of $5,000,000 shall be approved by the unaffiliated members
         of the Board of Directors of Lessee or such Restricted Subsidiary, as

         determined that such transaction complies with the foregoing
         provisions. If Lessee or any Restricted Subsidiary of Lessee enters
         into an Affiliate Transaction (or a series of related Affiliate
         Transactions related to a common plan) that involves an aggregate fair
         market value of more than $10,000,000, Lessee or such Restricted
         Subsidiary, as the case may be, shall, prior to the consummation
         thereof, obtain a favorable opinion as to the fairness of such
         transaction or series of related transactions to Lessee or the relevant
         Restricted Subsidiary, as the case may be, from a financial point of
         view, from a nationally

                                      -45-
<PAGE>
         recognized firm qualified to do the business for which it is engaged
         and file the same with Indenture Trustee.

         shall not apply to (A) reasonable fees and compensation paid to and
         indemnity provided on behalf of, officers, directors, employees or
         consultants of Lessee or any Restricted Subsidiary of Lessee as
         determined in good faith by Lessee's Board of Directors or senior
         management; (B) transactions exclusively between or among Lessee and
         any of its Wholly Owned Restricted Subsidiaries or exclusively between
         or among such Wholly Owned Restricted Subsidiaries, provided such
         transactions are not otherwise prohibited by this Agreement; (C) any
         agreement as in effect as of the Issue Date (including, but not limited
         to, the Weatherford Transition Services Agreement) or any amendment
         thereto or any transaction contemplated thereby (including, but not
         limited to, pursuant to any amendment thereto) in any replacement
         agreement thereto so long as any such amendment or replacement
         agreement is not more disadvantageous to the Tranche A Noteholders in
         any material respect than the original agreement as in effect on the
         Issue Date; (D) Restricted Payments permitted by Section 9.2(b); (E)
         the Tax Sharing Agreement; (F) employment agreements with officers and
         employees of Lessee and its Restricted Subsidiaries, in the ordinary
         course of business; (G) loans and advances to employees not to exceed
         $5,000,000 outstanding at any one time, in the ordinary course of
         business; (H) arrangements with directors of Lessee existing on the
         Issue Date as disclosed in the Offering Memorandum; (I) the Acquisition
         of Gas Services International Ltd. and related entities including

         approximately $21 million, if consummated within six (6) months of the
         Issue Date, and documents related thereto; and (J) the provision of
         compression or related services to Weatherford or any other Affiliate
         in the ordinary course of business on market terms; provided, however,
         that if aggregate payments or property involved in any such transaction
         or series of related transactions exceeds $5,000,000, such transaction
         or transactions shall be approved by the unaffiliated members of the
         Board of Directors of Lessee.

                  (i) Change of Control. Upon a Change of Control, Lessee shall
comply with Section 28.4.3 of the Lease Agreement.

                  (j) Conduct of Business. Lessee and its Restricted
Subsidiaries will not engage in any businesses which are not the same, similar
or reasonably related to the businesses in which Lessee and its Restricted
Subsidiaries are engaged on the Issue Date.

                  (k) Reports to Indenture Trustee. Lessee will deliver to
Indenture Trustee within fifteen (15) days after the filing of the same with the
Commission, copies of the quarterly and annual reports and of the information,
documents and other reports, if any, which Lessee is required to file with the
Commission pursuant to Section 13 or 15(d) of the Exchange Act. Further,
notwithstanding that Lessee may not be subject to the reporting requirements of
Section 13 or 15(d) of the Exchange Act, Lessee will provide Indenture Trustee

documents and other reports specified in Sections 13 and 15(d) of the Exchange
Act.

<PAGE>

                  (i) may sell or otherwise dispose of any Property which, in

     no longer useful in the conduct of such Person's business;

without limitation, any purchase, sale, lease or exchange of Property or the
rendering of any service, with any Affiliate (Tranche B) unless such
transactions are otherwise permitted under this Agreement, are in the ordinary

to it than it would obtain in a comparable arm's length transaction with a
Person not an Affiliate (Tranche B).

         (s) Subsidiaries. Without the prior written consent of the Majority
Tranche B Lenders, Lessee shall not, and shall not permit any Subsidiary to,

         (t) [Reserved].

         9.4. Covenant of Tranche B Lenders, Lessor, Administrative Agent and
Collateral Agent and Limited Partners. If Lessor, any Tranche B Lender,
Administrative Agent or Collateral Agent is not a U.S. Person, it shall provide,
to Lessee and to any other party making payments to it under the Operative
Documents, on the Closing Date (or, if later at the time it becomes Lessor, a
Tranche B Lender, Administrative Agent or Collateral Agent, as the case may be)
and at such times as may be necessary thereafter under Applicable Law as in
effect on the Closing Date (including Section 1441 of the Code) and at such
other times as shall be reasonably requested by Lessee or any other party making
payments to it under the Operative Documents, a fully completed Internal Revenue
Service Form W-8 or successor form (including an appropriate Internal Revenue
Service Form W-8 completed as specified in Treasury Regulations section
1.1441-4(a)), along with any other forms or documents required to be attached to
such forms upon which Lessee or such other party can rely establishing that all
payments to each such Person under the Operative Documents can be made free and
clear of any requirement to withhold any United States federal income tax
therefrom; provided, however, that each such Person shall not be required to
provide such forms if, solely as a result of a change after the Closing Date in
Applicable Law as in effect on the Closing Date (or such later date) such Person
is not legally entitled to deliver such form. In the event of a failure to
provide any form as required under this Section 9.4 by any Tranche B Lender,
Lessor, Administrative Agent or Collateral Agent, the relevant party shall be
entitled to withhold from any payment made pursuant to the Operative Documents
to such Person the appropriate amount of federal income tax, notwithstanding the
provisions of the Operative Documents to the contrary and provided further, that
Lessee shall not have any indemnity obligation to such Person pursuant to
Section 10.3.5 hereof to the extent related to such failure.

         9.5. Covenant of Lessee and Lessor. Each of Lessor and Lessee agrees
for the benefit of each Tranche B Lender that no item of equipment shall be
leased under the Lease Agreement (other than by way of a substitution of
equipment in accordance with Section 13 of the Lease Agreement) on a Funding
Date without satisfaction of the condition precedent set forth in Section 3.1(o)
with respect to such item, notwithstanding any waiver of such condition by any
other Tranche B Lenders.

         10. Indemnities.

         10.1. Lessee General Indemnification. Lessee hereby assumes liability
for, and does hereby agree to indemnify, protect, save, defend, and hold
harmless each Lessee Indemnified Person (and, with respect to clause (ix) below,
Arrangers) on an After-Tax Basis, from and against any and all obligations,
fees, expenses, costs, liabilities, losses, damages, penalties, claims, demands,
actions, suits, judgments and related costs and expenses, including reasonable
legal fees and expenses, of every kind and nature whatsoever, imposed on,
incurred by, or asserted against such Lessee Indemnified Person (collectively,
"Losses"), which relate in any way relate to or arise in any way out of (i) the
manufacture, construction, ordering, transfer, acceptance or rejection,
ownership, transfer of ownership, titling or re-titling, registration or
re-registration, delivery, leasing, subleasing, possession, use, operation,
maintenance, storage, removal, redelivery, repossession, mortgaging, granting of
any interest in, transfer of title to, acquisition, sale or other application or
disposition, disposition of licensing, documentation, of any Item of Equipment,
or any part thereof, including, without limitation, any of such as may

                                      -58-
<PAGE>

arise from (A) loss or damage to any property or death or injury to any Persons,
(B) patent or latent defects in any Items of Equipment (whether or not
discoverable by Lessee or any Lessee Indemnified Person, (C) any claims based on
strict liability in tort or negligence, (D) any claims related to the release of
any substance into the environment and (E) any claims based on patent,
trademark, trade name or copyright infringement, or (ii) the Operative Documents
or the transactions contemplated hereby or thereby, or (iii) any failure on the
part of Lessee or Guarantor to perform or comply with any Applicable Law, any of
the terms of any Operative Document to which it is a party or any instrument
referred to or contemplated hereby or thereby or the nonconformity of any
Equipment with Applicable Law, or (iv) reliance on any representation or
warranty made or deemed made by Lessee or Guarantor or any of their respective
officers under or in connection with any Operative Document which shall have
been false or incorrect in any material respect when made or deemed made or
delivered, or (v) any repayment to Lessee by Lessor of any amount previously
distributed hereunder which amount such Person is required to repay, or (vi) any
investigation, litigation or proceeding related to any Operative Document or the
use of proceeds of Tranche A Notes, Tranche B Loans or Equity Contributions or
the ownership of the Tranche A Notes, Tranche B Notes or Equity Certificates or
in respect of the Lease Agreement, or (vii) the failure to vest or maintain
vested in Lessor and Collateral Agent or to transfer to Lessor or Collateral
Agent an undivided security interest in the Lessee Collateral or the Lessor
Collateral, respectively, including collections free and clear of Liens to the
extent required by the Operative Documents, or (viii) any agreement by Lessor to
pay any amounts under Section 6.5 of the Limited Partnership Agreement or to
indemnify any Person under the Lessor Indemnity Agreement, or (ix) the
engagement of the Appraiser with respect to the delivery of any Appraisal to be
delivered in accordance with the Operative Documents. Lessee shall be subrogated
to a Lessee Indemnified Person's rights in any matter with respect to which
Lessee has actually reimbursed such Lessee Indemnified Person for amounts
expended by it or has actually paid such amounts directly pursuant to this
Section 10.1. In case any claim, action, suit or proceeding is made or brought
against any Lessee Indemnified Person in connection with any claim indemnified
against hereunder, such Lessee Indemnified Person will, promptly after receipt
of notice of such claim or the commencement of such action, suit or proceeding,
notify Lessee thereof, enclosing a copy of all papers served upon such Lessee
Indemnified Person, but failure to give such notice or to enclose such papers
shall not relieve Lessee from any liability hereunder unless such failure
materially and adversely affects Lessee's defense of such claim resulting in a
material increase in liability of Lessee in respect of such claim or preventing
it from reducing liability therefor, in which case Lessee shall not be required
to indemnify such Lessee Indemnified Person for the amount by which such
liability was increased or not reduced for failure to give such notice. Provided
no Lease Event of Default has occurred, Lessee will be entitled to participate
in, and assume the defense of, such claim, action, suit or proceeding, or cause
the same to be resisted or defended by counsel selected by Lessee and reasonably
acceptable to the Lessee Indemnified Person; provided, however, if such claim,
action, suit or proceeding involves any material risk of loss or forfeiture of
title to the Equipment (unless Lessee shall have posted a bond or other security
reasonably satisfactory to Administrative Agent in respect of such risk) or any
material risk of criminal penalty being assessed against any Lessee Indemnified
Person, upon such Lessee Indemnified Person's request, Lessee will at its
expense, cause such claim, action, suit or proceeding to be resisted or defended
by counsel selected by such Lessee Indemnified Person and reasonably acceptable
to Lessee. After notice from Lessee

                                      -59-
<PAGE>

to such Lessee Indemnified Person of Lessee's election to so assume the defense
of such claim, action, suit or proceeding, Lessee will not be liable to such
Lessee Indemnified Person for any costs and expenses of any settlement of such
claim, action, suit or proceeding effected by such Lessee Indemnified Person
without the prior written consent of Lessee (which consent will not be
unreasonably withheld). Such Lessee Indemnified Person may participate at its
own expense in any such claim, action, suit or proceeding controlled by Lessee
pursuant hereto; provided such participation does not, in the opinion of
independent counsel appointed by Lessee, interfere with such control) and such
participation will not constitute a waiver of the indemnification provided in
this Section 10. In the event of any failure by Lessee to satisfy its
obligations under this Section 10.1, Lessee shall pay all reasonable costs and
expenses (including, without limitation, attorney's fees and expenses) incurred
by such Lessee Indemnified Person in connection with such action, suit or
proceeding. Additionally, if outside counsel to such Lessee Indemnified Person
determines that a conflict of interest exists between such Person and Lessee
regarding any Loss indemnified hereunder, Lessee agrees to pay the reasonable
fees and expenses of separate counsel for and as selected by such Lessee
Indemnified Person. The provisions of this Section 10.1, and the obligations of
Lessee under this Section 10.1, shall apply from the date of this Agreement
notwithstanding that the Term may not have commenced, and shall survive and
continue in full force and effect notwithstanding the expiration or earlier
termination of this Agreement, the Lease Agreement or any other Operative
Document in whole or in part, including the expiration of termination of the
Term with respect to any Item of Equipment, and are expressly made for the
benefit of, and shall be enforceable by Lessor.

         10.2. Exceptions to Lessee's General Indemnification. Notwithstanding
the terms of Section 10.1, Lessee shall not be required to indemnify any Lessee
Indemnified Person under Section 10.1 for any of the following: (i) any Loss to
the extent resulting from the willful misconduct or gross negligence of such
Lessee Indemnified Person (it being understood that Lessee shall be required to
indemnify any Lessee Indemnified Person even if the ordinary (but not gross)
negligence of such Lessee Indemnified Person caused or contributed to such
Loss), (ii) any Loss resulting from Lessor Liens attributable to such Lessee
Indemnified Person, (iii) any Loss to the extent attributable to acts or events
occurring after the end of the Term, if any, so long as no Lease Event of
Default shall have occurred and be continuing and the Equipment has either been
purchased or redelivered in accordance with the terms of Section 6.1, 28.2, 28.3
or 28.4 of the Lease Agreement, (iv) any Loss (other than a Loss attributable to
a Lease Event of Default) arising from a breach by such Lessee Indemnified
Person of any agreement entered into in connection with the assignment or
participation of any interest of such Lessee Indemnified Person under the Lease
Agreement or the other Operative Documents, (v) any Loss to the extent arising
or resulting from the failure of such Lessee Indemnified Person to comply with
laws applicable to financial institutions or their affiliates generally or the
failure of such Lessee Indemnified Person to file any material notice, report,
filing or other document required by any Governmental Entity regulating banks or
their affiliates in connection with such Lessee Indemnified Person's execution
of, and participation in the transactions contemplated by, the Operative
Documents except to the extent resulting from the acts or omissions of Lessee or
Guarantor, (vi) any other expense or Loss to the extent expressly provided under
any of the Operative Documents to be paid or borne by such Lessee Indemnified
Person at its own expense, (vii) any Loss to the extent resulting from the
offer, sale, disposition or transfer by such Lessee

                                      -60-
<PAGE>

Indemnified Person of all or part of its interest in the Operative Documents,
other than a Loss arising as a result of the occurrence of a Lease Event of
Default, (viii) any Loss that is a Tax or based on a Tax, (ix) any Loss to the
extent resulting from any business, transaction or other activity in which such
Lessee Indemnified Person is engaged, which has no relation to the transactions
contemplated hereby or by any of the Operative Documents, (x) any Loss resulting
from a Tranche A Event of Default or Tranche B Event of Default not attributable
to a Lease Event of Default, (xi) any Loss which is an ordinary and usual
operating or overhead expense of such Lessee Indemnified Person except expenses
incurred relating to an Lease Event of Default, (xii) any Loss in connection
with any dispute between or among Lessee Indemnified Persons other than Losses
caused by a Lease Event of Default and (xiii) any Loss arising under Section
406(a) of ERISA or Section 4975 of the Code (a) as a result of Loans or funds
advanced by Tranche B Lenders or Lessor being deemed to be "plan assets" under
the "plan asset regulations" promulgated pursuant to ERISA or (b) as a result of
a violation of Section 406(b) of ERISA or Section 4975(c)(1) (E) or (F) of the
Code by Tranche B Lenders or Lessor. Section 10.1 shall be construed as an
indemnity only and not a guaranty of residual value of the Items of Equipment.

         10.3. Tax Indemnity.

                  10.3.1. General Indemnity. Subject to the other provisions of
this Section 10.3, Lessee agrees to pay, defend and indemnify and hold Lessor,
Indenture Trustee, Administrative Agent and Collateral Agent and their
respective Affiliates, successors and assigns (including any consolidated or
combined group of which any such Person is a member) (each a "Tax Indemnitee")
harmless on an After-Tax Basis from any and all federal, state, local and
foreign taxes, excise taxes, fees, withholdings, levies, documentary stamps,
imposts, duties, assessments, penalties and charges of any kind and nature
whatsoever, together with any penalties, fines or interest thereon (herein
called "Taxes") howsoever imposed, whether levied or imposed upon or asserted
against a Tax Indemnitee, Lessee, any Item of Equipment, or any part thereof, by
any federal, state or local government or taxing authority in the United States,
or by any taxing authority of a foreign country or subdivision thereof, upon or
with respect to (i) the Items of Equipment, any Item of Equipment or any part
thereof, (ii) the manufacture, construction, ordering, transfer, ownership,
transfer of ownership, titling or re-titling, registration or re-registration,
delivery, leasing, subleasing, possession, use, operation, maintenance, storage,
removal, return, mortgaging, granting of any interest in, transfers of title to,
acquisition, sale or other disposition of licensing, documentation,
repossession, sale or other acquisition or disposition of the Items of
Equipment, any Item of Equipment or any part thereof, (iii) the revenues, rent,
receipts or earnings arising from any Item of Equipment or any part thereof,
(iv) any Operative Document, (v) any Lease Payment or Supplemental Payment or
any payment made to Lessor, Indenture Trustee or any Tranche A Noteholder, any
Tranche B Lender, by Lessor or Lessee pursuant to the Operative Documents, or
(vi) otherwise in respect of the Operative Documents or any thereof or any
transaction or transactions contemplated hereby or thereby. Lessee further
agrees to defend and indemnify and hold Lessor harmless on an After-Tax Basis
from any and all Taxes howsoever imposed, whether levied or imposed upon or
asserted against any Person by any federal, state or local government or taxing
authority in the United States, or by any taxing authority of a foreign country
or subdivision thereof against which Lessor has agreed to indemnify such Person
under the Lessor Indemnity Agreement.

                  10.3.2. Exceptions to Tax Indemnity. Notwithstanding anything
to the contrary in Section 10.3.1, the following shall be excluded from the
indemnity provided under Section 10.3.1: (i) Taxes (other than Taxes that are,
or are in the nature of, sales, use, rental, value added, transfer or property
taxes) that are imposed on a Tax Indemnitee by the United States federal
government that are based on or measured by the gross or net income or gross or
net receipts, taxes based on capital gains and minimum taxes and any and all
withholding Taxes (which, for the avoidance of doubt, are dealt with in Section
10.3.5 hereof) of such Person; provided, that this clause (i) shall not be
interpreted to prevent a payment from being made hereunder on an After-Tax Basis
if such payment is otherwise required to be so made; (ii) Taxes (other than
Taxes that are, or are in the nature of, sales, use, rental, value added,
transfer or property taxes) that are imposed on any Tax Indemnitee (other than
Lessor) by any state, local or foreign jurisdiction or taxing authority within
any state or local or foreign jurisdiction and that are net income taxes, or are
franchise taxes, any gross income or gross receipts taxes imposed in lieu of a
net income tax, taxes based on capital gains and minimum taxes and any and all
withholding Taxes (which, for the avoidance of doubt, are dealt with in Section
10.3.5 hereof) of such Person; provided that such Taxes shall not be excluded
under this clause (ii) to the extent such Taxes would have been imposed had the
location, possession or use of any Equipment in, the location or the operation
of Lessee, Lessor or Guarantor in, or Lessor's, Lessee's or Guarantor's making
payments under the Operative Documents from, the jurisdiction imposing such
Taxes been the sole connection between such Tax Indemnitee and the jurisdiction
imposing such Taxes, unless, however, such Tax Indemnitee would have been
subject to tax in such jurisdiction absent the transactions contemplated by the
Operative Documents; provided further, that Lessor is indemnified for all Taxes
excluded by this subsection (ii); provided further, that this clause (ii) shall
not be interpreted to prevent a payment from being made on an After-Tax Basis if
such payment is otherwise required to be so made; (iii) provided that all
amounts due from Lessee under the Operative Documents have been paid, any Tax to
the extent it relates to any act, event or omission that occurs after the
termination of the Lease Agreement and, if required, redelivery or sale of an
Item of Equipment in accordance with the terms of the Lease Agreement (but not
any Tax that is otherwise excluded herein or is imposed with respect to such
termination, redelivery or sale or to any period prior to such termination,
redelivery or sale); (iv) any Taxes which are imposed on a Tax Indemnitee as a
result of the gross negligence or willful misconduct of such Tax Indemnitee
itself, as determined by a court of competent jurisdiction (as opposed to gross
negligence or willful misconduct imputed to such Tax Indemnitee), but not Taxes
imposed as a result of ordinary negligence of such Tax Indemnitee; (v) Taxes
imposed on, or increased (under Applicable Law in effect on the date of the
transfer) as a result of a voluntary transfer by the Tax Indemnitee or any
transfer as a result of the bankruptcy of such Tax Indemnitee not caused by a an
Event of Default under Section 23(a) of the Lease Agreement of any Item of
Equipment or interest therein or any interest in or arising under any Operative
Document or any transactions contemplated thereby other than any such transfer
required by law or by the Operative Document, occurring pursuant to the exercise
of remedies during the continuance of a Lease Event of Default or requested by
Lessee; (vi) with respect to Lessor, any Tax that results from or would not have
been imposed but for the breach or inaccuracy of any representation set forth in
Section 2.3 or 2.4 hereof, as the case may be; (vii) any Tax to the extent
resulting in whole or in part from the failure of any Tax Indemnitee to file a
return that is proper and timely unless such failure results from the failure of
Lessee to perform its obligations

                                      -62-
<PAGE>

under Section 10.3.4 hereof; and (viii) any Tax that results from or would not
have imposed but for the failure of any Tax Indemnitee, at Lessee's sole cost,
to provide any form, certificate or other document reasonably requested by,
prepared by and timely provided to such Tax Indemnitee by Lessee, legally able
to be provided by such Tax Indemnitee and necessary to avoid the imposition of
such Tax provided that such Tax Indemnitee reasonably determines that to so
provide such form, certificate or other document would have no adverse effect on
it.

                  10.3.3. Payment of Taxes. Subject to the terms of Section
10.3.6, Lessee agrees to pay or cause to be paid all Taxes indemnified pursuant
to Section 10.3.1 directly to the taxing authorities where feasible and
otherwise to the Tax Indemnitee, as appropriate, and Lessee shall at its own
expense, upon such Tax Indemnitee's reasonable request, furnish to such Tax
Indemnitee copies of official receipts or other reasonably satisfactory evidence
of such payment. In the case of Taxes for which no contest is conducted pursuant
to Section 10.3.6 and which Lessee pays directly to the taxing authorities,
Lessee shall pay such Taxes prior to the latest time permitted by the relevant
taxing authority for timely payment. In the case of Taxes for which a Lessee
reimburses a Tax Indemnitee, Lessee shall do so within thirty (30) days after
receipt by Lessee of demand by such Tax Indemnitee describing in reasonable
detail the nature of the Tax and the basis for the demand (including without
limitation the computation of the amount payable), accompanied by receipts or
other reasonable evidence of payment of the Tax in respect of such demand. In
the case of Taxes for which a contest is conducted pursuant to Section 10.3.6
Lessee agrees to pay such Taxes or reimburse such Tax Indemnitee for such Taxes,
to the extent not previously paid or reimbursed pursuant to Section 10.3.1,
prior to the latest time permitted by the relevant taxing authority for timely
payment after conclusion of all contests hereunder.

                  At Lessee's written request, the amount of any indemnification
payment by Lessee pursuant to Section 10.3.1 shall be verified and certified by
the independent public accounting firm regularly engaged by such Tax Indemnitee.
The fees and expenses of such independent public accounting firm shall be paid
by Lessee unless such verification shall result in an adjustment in Lessee's
favor of five percent (5%) or more of the payment as computed by the Tax
Indemnitee, in which case such fee shall be paid by the Tax Indemnitee.

                  10.3.4. Tax Filings. Lessee shall be responsible for preparing
and filing any real and personal property or ad valorem tax returns in respect
of the Equipment. In the case of any other report, statement or tax return that
shall be required to be made with respect to any Taxes which are indemnified by
Lessee pursuant to Section 10.3.1, Lessee, at its sole cost and expense, shall
notify the relevant Tax Indemnitee of such requirement and (except if such Tax
Indemnitee notifies Lessee that such Tax Indemnitee intends to prepare and file
such report or return) (i) to the extent required or permitted by and consistent
with filing requirements in the applicable jurisdiction, make and file in
Lessee's name such return, statement or report and (ii) in the case of any other
such return, statement or report required to be made in the name of such Tax
Indemnitee, advise such Tax Indemnitee of such fact and prepare such return,
statement or report for filing by such Tax Indemnitee or, where such return,
statement or report shall be required to reflect items in addition to any
obligations of Lessee under or arising out of Section 10.3.1, provide such Tax
Indemnitee at Lessee's expense with information sufficient to permit such
return, statement or report to be properly made with respect to any obligations
of Lessee under or arising out of Section 10.3.1. Such Tax Indemnitee shall,
upon Lessee's request and at

                                      -63-
<PAGE>

Lessee's expense, provide any data not deemed confidential by such Tax
Indemnitee maintained by such Tax Indemnitee (and not otherwise available to or
within the control of Lessee) with respect to the Equipment which Lessee may
reasonably require to prepare any required Tax returns or reports.

                  10.3.5. Withholdings. As between Lessee on one hand, and
Lessor, Administrative Agent and Collateral Agent (each a "Withholding Party")
on the other hand, Lessee shall be responsible for, and Lessee shall indemnify
and hold harmless each Withholding Party on an After Tax Basis against, any
obligation for United States or foreign withholding taxes or similar levies,
imposts, charges, fees, deductions or withholdings (collectively,
"Withholdings") imposed in respect of any part of the Lease Payments, interest
or other amounts payable by Lessee or Lessor to any Withholding Party, or with
respect to any other payments under the Operative Documents (all such payments
being referred to herein as "Exempt Payments" to be made without deduction,
withholding or set off) (and, if any Withholding Party receives a demand for
such payment from any taxing authority or a Withholding is otherwise required
with respect to any Exempt Payment, Lessee shall discharge such demand on behalf
of such Withholding Party); provided, however, that the obligation of Lessee
under this Section 10.3.5 shall not apply to any Withholdings that would not
have been imposed but for such Withholding Party's failure to comply with
Section 9.4.

                  If a Tax Indemnitee or a Withholding Party or any Affiliate
with whom such Tax Indemnitee or a Withholding Party files a consolidated tax
return (or equivalent) subsequently receives the benefit in any country of a tax
credit, deduction or other allowance or reduction resulting from Taxes or Losses
with respect to which it or an Affiliate has received a payment of an indemnity
amount from Lessee under Section 10.1 or 10.3, such Person will pay to Lessee
such part of that benefit as in the sole discretion of such Person will leave it
(after such payment) in a position no more and no less favorable than it would
have been in if no additional payment had been required to be paid, provided
always that (i) such Person will determine in its sole discretion, exercised in
good faith, the amount and allocation of any such benefit and of the date on
which it is received and of any After-Tax Basis calculation required with
respect to payments to or from it, (ii) such Person will have the absolute
discretion as to the order and manner in which it employs or claims tax credits
and allowances available to it and (iii) such Person will not be obliged to
disclose to Lessee any information regarding its tax affairs or tax
computations.

                  10.3.6. Tax Contests. If a claim is made in writing against
any Tax Indemnitee for any Taxes which Lessee is required to pay or indemnify
against pursuant to Section 10.3.1, such Tax Indemnitee shall promptly notify
Lessee in writing, provided that, without prejudice to any rights or claims for
damages Lessee may have as a result of such failure, the failure to so notify
Lessee will not reduce Lessee's obligation under Section 10.3 except if such
failure precludes the contest of such claim. Subject to the next sentence, if
requested by Lessee in writing within thirty (30) days after receipt by Lessee
of a notice described in the preceding sentence, such Tax Indemnitee and, if
required or appropriate to prosecute such contest, any other Tax Indemnitee,
shall permit such Lessee, to contest in the name of Lessee, and if such contest
by such Lessee in the name of such Lessee is not permissible or allowed, shall,
at the request of Lessee, permit such Lessee to contest in the name of the Tax
Indemnitee

                                      -64-
<PAGE>

and, if such contest by Lessee in the name of the Tax Indemnitee is not
permissible or allowed, shall, at the request of Lessee diligently contest in
good faith (including pursuing all administrative and judicial appeals) the
validity, applicability or amount of such Taxes in appropriate administrative or
judicial proceedings; provided that (i) prior to taking such action Lessee shall
have agreed to pay and shall have provided an undertaking reasonably acceptable
to such Tax Indemnitee with respect thereto or shall have paid each Tax
Indemnitee that is engaged in such contest in a satisfactory manner for all
out-of-pocket costs and expenses which such Tax Indemnitee may incur in
connection with contesting such claim, including, without limitation, all
reasonable legal and accountant's fees and disbursements and costs of
administrative and judicial proceedings, and the amount of any interest or
penalties which may be payable as a result of contesting such claim, (ii) if
such contest is to be initiated by the payment of, and the claiming of a refund
for, such Taxes (such election to be within the sole discretion of Lessee),
Lessee shall have advanced such Tax Indemnitee sufficient funds (on an
interest-free basis and on an After-Tax Basis) to make such payment, (iii) any
action to be taken will not result in a material risk of sale, forfeiture or
loss of Lessor's title to, or Lessor's or Collateral Agent's interest in, any
Item of Equipment unless Lessee shall have made provision against such risk in a
manner acceptable to such Tax Indemnitee in its sole discretion, (iv) such Tax
Indemnitee shall not have determined, based on an opinion of such Tax
Indemnitee's counsel, that such action is reasonably likely to result in adverse
consequences to the future tax liability of such Tax Indemnitee not indemnified
to such Tax Indemnitee's satisfaction and (v) Lessee shall have delivered to
such Tax Indemnitee a written acknowledgment of its liability hereunder for such
Taxes, provided that such acknowledgment shall not be binding on such Lessee if
the contest of such Taxes is resolved through a written opinion of an
adjudicator stating a basis for such resolution that demonstrates Lessee has no
liability to such Tax Indemnitee hereunder for such Taxes and provided further,
that such Lessee shall have no right to contest in the name of a Tax Indemnitee,
and such Tax Indemnitee shall itself contest, if the contest involves issues
with respect to which Lessee would not be required to indemnify such Tax
Indemnitee hereunder and which cannot be severed by reasonable efforts of such
Tax Indemnitee from all issues with respect to which Lessee would be liable
hereunder or the severance of which would adversely affect the position of such
Tax Indemnitee, and in any such contest such Tax Indemnitee may in its sole
discretion select the forum for such contest and determine in good faith the
manner in which such contest shall be conducted, including, without limitation,
the pursuit of appeals, but shall consult with Lessee and its counsel in good
faith with respect to such Lessee's interests with respect to contest. If a
claim for Taxes is made in writing against any Tax Indemnitee and such Tax
Indemnitee complies with its obligations under this Section 10.3.6, Lessee and
such Tax Indemnitee shall, for purposes of determining the amount, if any,
payable to such Tax Indemnitee under Section 10.3, be bound by the results of
any contest under this Section 10.3.6 (or by the final written assessment by the
relevant taxing authority, if Lessee elect not to contest under this Section
10.3.6) as to the amount of Tax due to the relevant taxing jurisdiction, the
validity and applicability of such Tax, and any stated reason as to the basis
for the imposition of such Tax contained in the final determination with respect
to such contest. If any Tax Indemnitee shall determine in its sole discretion
that it has either obtained a refund of or been granted a credit, deduction or
other allowance or reduction against Taxes for which Lessee is not obligated to
indemnify such Tax Indemnitee hereunder for amounts corresponding to all or any
part of any Taxes which Lessee shall have paid to any Tax Indemnitee or for
which Lessee shall have

                                      -65-
<PAGE>

reimbursed any Tax Indemnitee hereunder, such Tax Indemnitee shall, provided
that no Lease Event of Default shall have occurred and be continuing, pay to
Lessee an amount which is equal to the sum of the amount of such refund or
credit, deduction or other allowance or reduction, plus any interest received
(or credited against Taxes for which Lessee is not obligated to indemnify such
Tax Indemnitee hereunder) on such refund fairly attributable to any Taxes paid
by such Lessee or with funds provided by Lessee prior to the receipt of such
refund, reduced by any Taxes incurred by such Tax Indemnitee by reason of the
receipt or accrual of such refund and interest, and increased by any tax benefit
realized by Tax Indemnitee as a result of any payment by such Tax Indemnitee
made pursuant to this sentence so as to return such Tax Indemnitee to the same
net after-tax position it would have been in if the Taxes so refunded or
credited had not been imposed; provided further, that a Tax Indemnitee shall not
be obligated to pay any Lessee an amount in excess of all amounts of Taxes (and
additional amounts described in Section 10.3) previously paid by Lessee pursuant
to Section 10.3 to such Tax Indemnitee, provided further, however, that such Tax
Indemnitee shall pay any amounts that it is not required to pay to Lessee solely
by reason of the foregoing proviso at such time as Lessee shall have made any
additional payments to such Indemnitee pursuant to Section 10.3 hereof equal to
such amounts, and if a Lease Event of Default shall have occurred and be
continuing, such Tax Indemnitee shall have the option of applying the amount
otherwise due any Lessee pursuant to this sentence against Lessee obligations
under any Operative Document or of holding such amount as security for Lessee
full performance of such obligations until the earlier of (x) the date all
obligations owed to such Tax Indemnitee under the Operative Documents have been
paid in full and (y) the curing of such Lease Event of Default, after which such
Tax Indemnitee shall pay such amount to Lessee. Any Tax Indemnitee shall be
entitled to settle any claim that is the subject of a contest hereunder without
the consent of Lessee provided that, in so doing, such Tax Indemnitee shall
waive any rights to indemnification by Lessee with respect to such settled claim
and any other claim the contest of which would be precluded as a result of such
settlement hereunder and shall repay to Lessee any amounts advanced to pay such
contested Taxes with interest actually received in respect thereof and release
any undertaking required hereunder.

                  10.3.7. Special Tax Indemnity. Lessee shall pay and assume all
liability for, and does hereby agree to indemnify each Tax Indemnitee on an
After Tax Basis for any tax, addition to tax, penalty, or other cost as a result
of the breach, inaccuracy or incorrectness of the representation found in
Section 2.1(j). Notwithstanding anything to the contrary in this Section 10.3.7,
Lessee shall not be obligated to indemnify any Tax Indemnitee pursuant to this
Section 10.3.7 in respect of any tax, penalty, or other cost that results from
or would not have occurred but for any failure by such Tax Indemnitee to provide
the information requested by Lessee in accordance with Section 2.1(j). Any claim
under this Section 10.3.7 shall be subject to the contest provisions of Section
10.3.6 (applied as if such claim were in respect of a Tax indemnified by Lessee
under Section 10.3.1) and the verification provisions of Section 10.3.3 (applied
as if the amount to be paid under this Section 10.3.7 was a payment required
under Section 10.3.1 hereof).

         10.4. Increased Costs, Illegality, etc. Lessee hereby assumes liability
for, and does hereby agree to indemnify, protect, save, defend and hold harmless
Lessor on an After-Tax Basis, from and against any and all amounts that Lessor
is obligated to pay any Tranche B Lender

                                      -66-
<PAGE>

under Section 2.7 of the Tranche B Loan Agreement or any Limited Partner under
Section 6.5 of the Limited Partnership Agreement.

         Lessor shall promptly, or Administrative Agent may, give notice (by
telephone promptly confirmed in writing) to Lessee of each claim under this
Section 10.4 which written notice shall show in reasonable detail the basis for
the calculation thereof and shall, absent manifest error, be final and
conclusive and binding on all the parties hereto).. Lessee shall pay to Lessor,
or at Administrative Agent's direction, the Person to whom Lessor has obligation
to pay such amount, within fifteen (15) days of the earlier of Lessor's and
Administrative Agent's written request therefor, such amounts owed by Lessor to
such Person.

         10.5. Lessee Indemnity. Lessee hereby assumes liability for, and does
hereby agree to indemnify, protect, save, defend, and hold harmless Lessor on an
After-Tax Basis from and against any and all Losses and each Tax Indemnitee
against any and all amounts owed by Lessor under the Loan Agreement to the
extent that there is a Lease Payment corresponding to the Loan payment for which
the indemnity is claimed under Section 10.2 hereof.

         10.6. Survival. All obligations provided for in this Section 10 shall
survive the resignation or removal of Administrative Agent or Collateral Agent
under Section 11.7, the sale of any Item of Equipment, any termination of the
Lease Agreement, the termination of this Agreement, and the payment in full of
the Tranche A Notes, the Tranche B Loans, the Equity Certificates and all
amounts arising under the Lease Agreement, Tranche A Notes, Tranche B Loans and
Limited Partnership Agreement.

         11. Administrative Agent and Collateral Agent.

         11.1. Authorization and Action of Administrative Agent.

         (a) (i) Indenture Trustee for itself and on behalf of Tranche A
Noteholders and (ii) each Tranche B Lender hereby appoints and authorizes
Administrative Agent to take such action as agent on their behalf and to
exercise such powers under this Agreement and the other Operative Documents as
are delegated to Administrative Agent by the terms hereof and thereof, together
with such powers as are reasonably incidental thereto. Except as otherwise
provided in the Limited Partnership Agreement, Administrative Agent shall act
solely as agents for Indenture Trustee and Tranche B Lenders and does not assume
nor shall be deemed to assume any obligation or relationship of trust or agency
with any of Lessee, Lessor, or Guarantor. As to any matters not expressly
provided for by a Operative Document (including enforcement or collection of the
Tranche A Notes or Tranche B Loans), Administrative Agent shall not be required
nor authorized to exercise any discretion or take any action, but shall be
required to act or to refrain from acting (and shall be fully protected in so
acting or refraining from acting) upon the instructions of (i) Indenture Trustee
acting on behalf of Majority Tranche A Noteholders, and (ii) Majority Tranche B
Lenders, and such instructions shall be binding, in the case of instructions
under clause (i), upon Indenture Trustee and each Tranche A Noteholder and, in
the case of instructions under clause (ii), upon each Tranche B Lender;
provided, however, Administrative Agent shall not be required to take any action
which exposes it to personal liability or which is contrary to any Operative
Document or Applicable Law. Administrative

                                      -67-
<PAGE>

Agent agrees to give to Indenture Trustee, and Tranche B Lenders prompt notice
of each notice given to it by Lessor or Lessee pursuant to the terms of this
Agreement; provided, however, Administrative Agent shall not be deemed to have
any notice of a Loan Default or Loan Event of Default unless it has received
notice of such from another party hereto. Administrative Agent may, with the
prior consent of Indenture Trustee acting on behalf of Majority Tranche A
Noteholders, or Majority Tranche B Lenders, as the case may be, agree to any
waiver or amendment of the Operative Documents on behalf of all Tranche A
Noteholders, or all Tranche B Lenders, as the case may be; provided, however,
Administrative Agent will not, without the prior consent of (i) Indenture
Trustee acting on behalf of all Tranche A Noteholders, and (ii) all Tranche B
Lenders, agree to any waiver or amendment that would (A) postpone the time or
times for payment of any amount payable under this Agreement or the Lease
Agreement or (B) reduce any Lease Payment payable under this Agreement or the
Lease Agreement. Administrative Agent will not, without the prior consent of (i)
Indenture Trustee on behalf of all Tranche A Noteholders and (ii) all Tranche B
Lenders, agree to any waiver or amendment that would, prior to the payment in
full of the Secured Obligations, release all or substantially all of the Lessor
Collateral from the Lien created by the Security Documents, other than in
accordance with the terms of the Operative Documents. Administrative Agent shall
pursue the remedies under the Operative Documents following a Loan Event of
Default in good faith and in a commercially reasonable manner and in accordance
with the instructions of Majority Tranche B Lenders provided, however,
Administrative Agent shall be under no obligation to pursue such remedies unless
such Majority Tranche B Lenders have offered to Administrative Agent security or
indemnity satisfactory to it as to the terms, coverage, duration, amount or
otherwise with respect to the costs, expenses and liabilities that may be
incurred by it in compliance with such written instructions, requests or
directions; provided further Administrative Agent shall not, without the consent
of (i) Indenture Trustee in accordance with the terms of the Indenture and (ii)
Majority Tranche B Lenders (A) approve any plan of reorganization or liquidation
arising out of a Lease Event of Default of the type described in Section 23(h)
of the Lease Agreement, a Tranche A Event of Default of the type described in
Sections 5.01(h) and (i) of the Indenture or a Tranche B Event of Default of the
type described in Section 5.1.4 of the Tranche B Loan Agreement (B) approve,
sell or cause the sale of Equipment in a single transaction or a series of
related transactions of Equipment with value in excess of $30,000,000 (other
than a sale in accordance with the terms of the Lease Agreement provided no
Lease Event of Default has occurred and is continuing). The appointment and
authority of Administrative Agent hereunder shall terminate upon the
indefeasible payment in full of all amounts owed Indenture Trustee, each Secured
Party, Administrative Agent and Collateral Agent under the Operative Documents.

         (b) (i) Indenture Trustee, for itself and on behalf of Tranche A
Noteholders, and (ii) each Tranche B Lender hereby appoints and authorizes
Collateral Agent to take such action as agent on their behalf and to exercise
such powers under this Agreement and the other Operative Documents as are
delegated to Collateral Agent by the terms hereof and thereof, together with
such powers as are reasonably incidental thereto. Collateral Agent shall act
solely as agent for Indenture Trustee and Tranche B Lenders and does not assume
nor shall be deemed to assume any obligation or relationship of trust or agency
with any of Lessee, Lessor, Limited Partners, Lessor General Partner or
Guarantor. As to any matters not expressly provided for by a Operative Document
(including enforcement or collection of the Tranche A Notes or the Tranche

                                      -68-
<PAGE>

B Loans), Collateral Agent shall not be required nor authorized to exercise any
discretion or take any action, but shall be required to act or to refrain from
acting (and shall be fully protected in so acting or refraining from acting)
upon the instructions of Administrative Agent acting on behalf of Secured
Parties, and such instructions shall be binding upon Indenture Trustee and all
Secured Parties; provided, however, Collateral Agent shall not be required to
take any action which exposes it to personal liability or which is contrary to
any Operative Document or Applicable Law. Collateral Agent agrees to give to
Indenture Trustee and Tranche B Lenders prompt notice of each notice given to it
by Lessor or Lessee pursuant to the terms of this Agreement; provided, however,
Collateral Agent shall not be deemed to have any notice of a Loan Default or
Loan Event of Default unless it has received notice of such from another party
hereto. Collateral Agent shall pursue the remedies of Secured Parties under the
Operative Documents following a Loan Event of Default in accordance with the
instructions of Administrative Agent; provided, however, Collateral Agent shall
be under no obligation to pursue such remedies unless one or more Tranche B
Lenders have offered to Collateral Agent security or indemnity satisfactory to
it as to the terms, coverage, duration, amount or otherwise with respect to the
costs, expenses and liabilities that may be incurred by it in compliance with
such written instructions, requests or directions. The appointment and authority
of Collateral Agent hereunder shall terminate upon the indefeasible payment in
full of all amounts owed Indenture Trustee, each Secured Party, Administrative
Agent and Collateral Agent under the Operative Documents.

         (c) Lessor and Tranche B Lenders hereby designate Administrative Agent,
and Administrative Agent hereby agrees, to calculate the interest due on the
Tranche B Loans, the Equity Yield and the Floating Lease Payments on each
Floating Payment Date and give notice of such amounts to Lessee, Lessor, and
each Tranche B Lender at least two (2) Business Days before such Floating
Payment Date.

         11.2. Delegation of Duties. Administrative Agent and Collateral Agent
may execute any of their duties under these Operative Documents through agents
or attorneys-in-fact and shall be entitled to advice of counsel concerning all
matters pertaining to such duties. Neither Administrative Agent nor Collateral
Agent shall be responsible for the negligence or misconduct of any agents or
attorneys-in-fact selected by it with reasonable care.

         11.3. Agent's Reliance, etc. Neither Administrative Agent nor
Collateral Agent nor any of their respective directors, officers, agents or
employees shall be liable for any action taken or omitted by it or them under or
in connection with any Operative Document, except for its or their own gross
negligence or willful misconduct. Without limitation of the generality of the
foregoing, each of Administrative Agent and Collateral Agent (i) may consult
with legal counsel (including counsel for Lessee), independent public
accountants and other experts selected by it and shall not be liable for any
action taken or omitted in good faith by it in accordance with the advice of
such counsel, accountants or experts, (ii) makes no warranty or representation
to Indenture Trustee or Secured Parties and shall not be responsible to
Indenture Trustee or Secured Parties for any statements, warranties or
representations made in or in connection with any Operative Document, (iii)
shall not have any duty to ascertain or to inquire as to the performance or
observance of any of the terms, covenants or conditions of any Operative
Document on the part of Lessee or Lessor or to inspect the property (including
the books and records) of Lessee or Lessor, (iv) shall not be responsible to
Indenture Trustee or

                                      -69-
<PAGE>

Secured Parties for the due execution, legality, validity, enforceability,
genuineness, sufficiency or value of any Operative Document or any other
instrument or document furnished pursuant thereto, and (v) shall incur no
liability under or in respect of any Operative Document by acting upon any
notice, consent, certificate or other instrument or writing (which may be by
fax, telegram, cable or telex) believed by it to be genuine and signed or sent
by the proper party or parties (including, but not limited to any notice,
consent, certification, other instrument or writing from Indenture Trustee
purportedly on behalf of Tranche A Noteholders or from Administrative Agent
purportedly on behalf of any Tranche A Noteholders or from Administrative Agent
purportedly on behalf of any Secured Parties. The permissive right of
Administrative Agent and Collateral Agent to take the actions permitted by this
Agreement shall not be construed as an obligation or duty to do so.

         11.4. Administrative Agent, Collateral Agent and Affiliates. With
respect to any Tranche B Loans or Equity Contributions made by it, any Tranche A
Note purchased by it or any Equity Certificate held by it, each of
Administrative Agent and Collateral Agent shall have the same rights and powers
under each Operative Document as any other Tranche B Lender or Limited Partner
as the case may be and may exercise the same as though it were not an agent
hereunder. Administrative Agent and Collateral Agent and their respective
Affiliates may accept deposits from, lend money to, act as trustee under
indentures of, and generally engage in any kind of business with, Lessor, Lessee
or Guarantor, any of their Affiliates and any Person who may do business with or
own securities of Lessor, Lessee or Guarantor or any such Affiliate, all as if
Administrative Agent and Collateral Agent were not an agent hereunder and
without any duty to account therefor to any other party hereto.

         11.5. Credit Decisions. Each Tranche B Lender acknowledges that it has,
independently and without reliance upon Administrative Agent or Collateral
Agent, and based on the financial statements of Lessee and Guarantor and such
other documents and information as it has deemed appropriate, made its own
credit analysis and decision to enter into this Agreement and the other
Operative Documents. Each Tranche B Lender also acknowledges that it will,
independently and without reliance upon Administrative Agent or Collateral
Agent, as the case may be and based on such documents and information as it
shall deem appropriate at the time, continue to make its own credit decisions in
taking or not taking action under the Operative Documents.

         11.6. Indemnification. Each Tranche B Lender agrees to indemnify
Administrative Agent and Collateral Agent, (to the extent not reimbursed by
Lessor or Lessee) ratably according to its pro rata share on the aggregate
outstanding balances of the Tranche B Loans ("Indemnity Pro Rata Share"), from
and against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements of any kind or
nature whatsoever which may be imposed on, incurred by or asserted against
Administrative Agent or Collateral Agent in any way relating or arising out of
any Operative Document or any action taken or omitted by Administrative Agent or
Collateral Agent under any Operative Document in their capacities as agents for
such Person; provided that no Tranche B Lender shall be liable to Administrative
Agent or Collateral Agent hereunder for any portion of such liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements resulting from such Administrative Agent's or such
Collateral Agent's gross

                                      -70-
<PAGE>

negligence or willful misconduct. Without limitation of the foregoing, each
Tranche B Lender agrees to reimburse Administrative Agent and Collateral Agent
ratably according to its Indemnity Pro Rata Share promptly upon demand for
out-of-pocket expenses (including counsel fees) incurred by Administrative Agent
or Collateral Agent in connection with the preparation, execution, delivery,
administration, modification, amendment or enforcement (whether through
negotiations, legal proceedings or otherwise) of, or legal advice in respect of
rights or responsibilities under, Operative Document in their capacities as
agents for such Person, to the extent that Administrative Agent or Collateral
Agent is not reimbursed for such expenses by Lessor or Lessee. Neither Lessee's
nor Lessor's indemnity obligations shall be reduced by this Section 11.6.

         11.7. Successor Administrative Agent and Collateral Agent; Termination
of Agency. Administrative Agent and Collateral Agent may resign at any time by
giving at least fifteen (15) days written notice thereof to Indenture Trustee,
each Tranche B Lender, Lessor and Lessee, and each of Administrative Agent and
Collateral Agent may be removed at any time with or without cause by Indenture
Trustee acting on behalf of Majority Tranche A Noteholders together with
Majority Tranche B Lenders. Upon any resignation or removal of Administrative
Agent or Collateral Agent, Majority Tranche B Lenders shall have the right with,
provided no Lease Event of Default shall have occurred and be continuing, the
consent of Lessee (such consent not to be unreasonably withheld or delayed) to
appoint a successor Administrative Agent who shall be reasonably acceptable to
Lessee (it being understood and agreed that any non-defaulting Tranche B Lender
is deemed to be acceptable to Lessee) and not objected to by Indenture Trustee
on behalf of Majority Tranche A Noteholders. If no successor Administrative
Agent or Collateral Agent shall have been so appointed by Majority Tranche B
Lenders within thirty (30) days after any such resignation of removal, the
retiring Administrative Agent or Collateral Agent may, appoint a successor
Administrative Agent or Collateral Agent which shall be a commercial bank
organized under the laws of the United States of America or of any State thereof
and having a combined capital and surplus of at least $100,000,000. Upon the
acceptance of any appointment as Administrative Agent or Collateral Agent
hereunder by a successor Administrative Agent or Collateral Agent, such
successor Administrative Agent or Collateral Agent shall thereupon succeed to
and become vested with all the rights, powers, privileges and duties of the
retiring Administrative Agent or Collateral Agent, and the obligations under
each Operative Document. Any Administrative Agent or Collateral Agent resigning
in accordance with this Section 11.7 shall retain the benefits of Section 11 as
to any actions taken or omitted to be taken by it while it was Administrative
Agent or Collateral Agent.

         11.8. Registration.

         (a) Tranche A Notes. The Tranche A Notes shall be registered in
accordance with the terms of the Indenture.

         (b) Tranche B Notes. Administrative Agent shall preserve registration
books identifying each Tranche B Lender's interest in the Tranche B Notes and a
list of the names and addresses of the holders of the Tranche B Notes, which
register and list shall be available to each Party hereto or their respective
representatives for inspection (the "Register"). Ownership of the Tranche B
Notes shall be proved by the Register. No transfer by any holder of a Tranche B
Note

                                      -71-
<PAGE>

or any portion thereof shall be effective unless and until such transfer is made
upon the registration books maintained by Administrative Agent. Prior to due
presentment for registration of transfer of any Tranche B Note, Administrative
Agent, Collateral Agent, Lessee and Lessor shall deem and treat the Person in
whose name any Tranche B Note is registered as the absolute owner of such
Tranche B Note for the purpose of receiving payment of principal of, and
Breakage Costs, if any, and interest on such Tranche B Note and for all other
purposes whatsoever, whether or not such Tranche B Note is overdue, and neither
Administrative Agent, Collateral Agent, Lessor, nor Lessee shall be affected by
any notice to the contrary.

         (c) Lease Agreement. Administrative Agent shall preserve registration
books identifying each Person holding any interest of Lessor in the Lease
Agreement and registering any assignment of such interest effected in compliance
with Section 12.7. Except for the interests of Collateral Agent pursuant to the
Operative Documents, no transfer by Lessor of any holder of Lessor's interest in
the Lease Agreement shall be effective unless and until such transfer is made
upon the registration books maintained by Administrative Agent.

         12. Miscellaneous.

         12.1. Expenses. Lessor agrees to pay, to the extent that it has Tranche
A Premium or Accrued Interest Premium available to it for the payment of such,
within ten (10) Business Days of written notice thereof (or such earlier time as
may be agreed by Lessor or Lessee) (i) the reasonable fees and expenses (initial
and ongoing) of Indenture Trustee for serving as Indenture Trustee to Tranche A
Noteholders, of Lessor General Partner for serving as such and of Indenture
Trustee, Lessor, Lessor General Partner, Bankers Trust Company as a Tranche B
Lender, Deutsche Bank AG, New York Branch as Limited Partner, Administrative

the consummation of the transactions contemplated thereby including the expenses
of Lessor and Co-Obligor for auditing, legal, filing fees and related expenses
associated with the registration of the Tranche A Notes, compliance with its
obligations under the Indenture and Registration Rights Agreement and compliance
with TIA, the Securities Exchange Act and the Securities Act and (ii) any fees
payable to Arranger or any other Person as agreed in writing by either Lessor or

Interest Premium received by Lessor on such day, if any, less the amount of any
of the expenses and fees paid by Lessor on such date in accordance with the
previous sentence. Lessee agrees to pay all of the fees and expenses described
in clauses (i) and (ii) of the first sentence of this Section 12.1 (other than
the payment of principal or interest on the Tranche A Notes or Tranche B Loans
or other than as a result of a Loan Event of Default not caused by or arising
out of a Lease Event of Default) to the extent such fees and expenses are not
paid by Lessor on the due date therefor. Lessee agrees to pay the reasonable
fees and disbursements of special counsel to each of Lessor, Lessor General
Partner, Indenture Trustee, Administrative Agent and Collateral Agent (other
than Excluded Expenses) in connection with any amendments, waivers or consents
requested by Lessor, Lessee or Guarantor under any Operative Document. Upon the
occurrence and during

                                      -72-
<PAGE>

the continuance of any Lease Event of Default, Lessee agrees to pay or reimburse
each of Indenture Trustee, each Tranche A Noteholder, each Tranche B Lender,
Lessor, Lessor General Partner, Administrative Agent and Collateral Agent for
reasonable costs and expenses of counsel and of financial advisors as shall have
been selected by such Person to assist them in connection with such Lease Event
of Default.

         12.2. Amendments, Consents and Waivers.

         (a) Except as otherwise expressly provided and subject to the rights
assigned by Lessor to Collateral Agent hereunder, neither this Agreement nor any
other Operative Document (other than the Limited Partnership Agreement) nor any

scheduled maturity of such Tranche A Note, or reduce the rate or extend the time
of payment of interest thereon (except (x) in connection with the waiver of
applicability of any post-default increase in interest rates and (y) that any
amendment or modification that is agreed to by Indenture Trustee acting on
behalf of Majority Tranche A Noteholders directly affected thereby to the
financial definitions in the Operative Documents shall not constitute a
reduction in the rate of interest or fees for purposes of this clause (A)
notwithstanding the fact that such amendment or modification would otherwise
actually result in such a reduction, so long as the primary purpose (as
determined in good faith by Lessee and Administrative Agent) of the respective
amendment or modification was not to decrease the pricing pursuant to this
Agreement and the other Operative Documents), or reduce the principal amount
thereof (except to the extent repaid in cash), (B) release all or substantially
all of Collateral Agent's interest in the Lessor Collateral (except as expressly
provided herein), (C) reduce the percentage specified in the definition of

acting on behalf of Majority Tranche B Lenders directly affected thereby to the
financial definitions in the Operative Documents shall not constitute a
reduction in the rate of interest or fees for purposes of this clause (A),
notwithstanding the fact that such amendment or modification would otherwise

this Section 12.2(a)) or (E) extend or increase the amount of its Tranche B
Commitment, (iii) without the consent of Indenture Trustee, amend, modify or
waive any provision relating to the rights of Indenture Trustee, (iv) without
the consent of Administrative Agent, amend, modify or waive any provision
relating to the rights or obligations of Administrative Agent, (v) without the

B Notes, any of the terms of Sections 6, 10(b), 11 (except where any such
amendment, supplement, waiver or modification of maintenance obligations would
impair the value of any Item of Equipment in any material respect), 17, 28.3,
29.3 and 29.4 of the Lease Agreement. Administrative Agent agrees to deliver to
Indenture Trustee notice of any amendment of Section 11 of the Lease Agreement
made in accordance with this Section 12.2.(b).

termination to any of the provisions of this Agreement or any other Operative
Document, the consent of all Tranche B Lenders is required and the consent of
Majority Tranche B Lenders (but not all Tranche B Lenders) is obtained, then
Lessee shall have the right to replace each such non-consenting Tranche B Lender
(so long as all non-consenting Tranche B Lenders are so replaced) with one or
more Replacement Tranche B Lenders, pursuant to Section 12.7 so long as at the
time of such replacement, each such Replacement Tranche B Lender consents to the
proposed change, waiver, discharge or termination; provided however, no Tranche
B Lender shall be obligated to assign its rights hereunder unless all of its
interest or the interest of any Affiliate thereof in Lessor is assigned in
accordance with the terms of the Limited Partnership Agreement.

as the lessee of each Item of Equipment and (ii) for all federal, state and

(A) the Operative Documents will be treated as a financing arrangement, (B)
Lessor will be deemed a lender making loans to Lessee in an amount equal to the
sum of the aggregate of the outstanding Equity Contributions and the outstanding
principal amount of the Tranche A Notes and Tranche B Loans and (C) Lessee will
be treated as the owner of each Item of Equipment and will be entitled to all
tax benefits ordinarily available to an owner of equipment like the Equipment

characteristics of the Operative Documents and that such party has obtained and
relied upon and agree that they will obtain and rely upon such tax, accounting
and legal advice from their own accountants and counsel concerning the Operative
Documents as they deems appropriate.

         12.6. Descriptive Headings, etc. The descriptive headings used in this
Agreement are for convenience only and shall not be deemed to affect the meaning
or construction of any provision hereof.

         12.7. Benefit of Agreement; Assignment. This Agreement shall be binding
upon and inure to the benefit of the parties hereto and their respective
successors and permitted assigns and in particular any holder from time to time

Lender without the prior written consent of each other party hereto, may assign
any or all of its rights or obligations hereunder or under any other Operative
Document to which it is a party; provided, however,

                  (i) Lessor General Partner may at any time transfer or assign
     any or all of its rights or obligations under the Operative Documents in
     accordance with the provisions of Article 9 of the Limited Partnership
     Agreement;

                  (ii) Indenture Trustee may at any time transfer or assign any
     or all of its rights or obligations under the Operative Documents in
     accordance with the provisions of Section 6.8 or 6.9 of the Indenture;

                  (iii) Any Tranche B Lender may transfer, assign or grant
     participations in its rights in the Operative Documents; provided, however,
     such Tranche B Lender shall remain a "Tranche B Lender" for all purposes
     hereunder and the transferee, assignee or participant, as the case may be,
     shall not constitute a "Tranche B Lender" hereunder and, provided further,
     that no Tranche B Lender shall transfer or grant any participation under
     which the participant shall have rights to approve any amendment to or
     waiver of this Agreement or any other Operative Document except to the
     extent such amendment or waiver would (A) extend the final scheduled
     maturity of any Tranche B Loan which such participant is participating, or
     reduce the rate or extend the time of payment of interest or fees thereon
     (except in connection with a waiver of applicability of any post-default
     increase in interest rates) or reduce the principal amount thereof, or
     increase the amount of the participant's participation over the amount
     thereof then in effect (it being understood that a waiver of any Loan
     Default or Loan Event of Default shall not constitute a change in the terms
     of such participation, and that an increase in any Tranche B Loan shall be
     permitted without the consent of any participant if the participant's
     participation is not increased as a result thereof), (B) consent to the
     assignment or transfer by Lessor or Lessee of any of its rights and
     obligations under the Operative Documents or (C) release all or
     substantially all of the Collateral under all of the Security Documents
     (except as expressly provided in the Operative Documents) securing the
     Tranche B Loans in which such participant is participating. In the case of
     any such participation, the participant shall not have any rights under any
     Operative Documents (the participant's rights against such Tranche B Lender
     in respect of such participation to be those set forth in the agreement
     executed by such Tranche B Lender in favor of the participant relating
     thereto) and all amounts payable by Lessor and Lessee under the Operative
     Documents shall be determined as if such Tranche B Lender had not sold such
     participation;

                  (iv) Notwithstanding the foregoing, any Tranche B Lender (or
     any Tranche B Lender together with one or more other Tranche B Lenders) may
     (A) assign all or a portion of its rights and obligations under the
     Operative Documents to (x) its parent company and/or any affiliate of such
     Tranche B Lender which is at least 50% owned by such Tranche B Lender or
     its parent company or to one or more Tranche B Lenders or (y) in the case
     of any Tranche B Lender that is a fund that invests in loans, any other
     fund that invests in loans and is managed or advised by the same investment
     advisor of such Tranche B Lender or by an Affiliate of such investment
     advisor or (B) assign all, or if less

                                      -79-
<PAGE>

     than all, a portion of outstanding principal balance equal to at least
     $5,000,000 in the aggregate for the assigning Tranche B Lender or assigning
     Tranche B Lenders of such Tranche B Loan and related outstanding
     obligations hereunder or under the Tranche B Loan Agreement to one or more
     Eligible Transferees (treating any fund that invests in loans and any other
     fund that invests in loans and is managed or advised by the same investment
     advisor of such fund or by an Affiliate of such investment advisor as a
     single Eligible Transferee), each of which assignees shall become a party
     to this Agreement and the Tranche B Loan Agreement as a Tranche B Lender by
     execution of an Assignment and Assumption Agreement, provided that (w) new
     Tranche B Notes will be issued, at Lessee's expense, to such new Tranche B
     Lender and to the assigning Tranche B Lender upon the request of such
     Person, such new Tranche B Notes to be in conformity with the requirements
     of Section 2.3 of the Tranche B Loan Agreement, (x) the consent of
     Administrative Agent, Lessee and Lessor shall be required in connection
     with any assignment to an Eligible Transferee pursuant to clause (B) above
     (which consents shall not be unreasonably withheld), provided that the
     consent of Lessor shall not be required at any time that a Loan Event of
     Default has occurred and is continuing and the consent of Lessee shall not
     be required at any time that a Lease Event of Default has occurred and is
     continuing, (y) Administrative Agent shall receive for its own account at
     the time of each such assignment, from the assigning or assignee Tranche B
     Lender, the payment of a non-refundable assignment fee of $3,500 and (z)
     promptly after such assignment, Lessor and Lessee shall have received from
     Administrative Agent notice of any such assignment, together with the copy
     of the Assignment and Assumption Agreement relating thereto. To the extent
     of any assignment pursuant to this Section 12.7, the assigning Tranche B
     Lender shall be relieved of its obligations hereunder. At the time of each
     assignment pursuant to this Section 12.7 to a Person which is not already a
     Tranche B Lender hereunder and which is not a U.S. Person (as such term is
     defined in Section 7701(a)(30) of the Code) for federal income tax
     purposes, the respective assignee Tranche B Lender shall, to the extent
     legally entitled to do so, provide to Lessor and Lessee, the forms
     described in such Section 9.4 of the Participation Agreement. To the extent
     that an assignment of all or any portion of a Tranche B Lender's interests
     would, at the time of such assignment, result in additional increased costs
     under Section 2.7 of the Tranche B Loan Agreement from those that would
     have been incurred by the respective assigning Tranche B Lender prior to
     such assignment, then Lessee shall not be obligated to pay such incremental
     additional increased costs (although Lessee shall be obligated to pay any
     other increased costs of the type described above resulting from changes
     after the date of the respective assignment);

                  (v) Each Tranche B Lender shall provide written notice to
     Administrative Agent of any assignment or participation by such Tranche B
     Lender of any interest it may have under any Operative Document. In the
     case of any participations, other than to which Lessee otherwise consents,
     the right of any such participant to indemnification or other amounts under
     Section 10 shall be limited to amounts which would have been due had no
     such participation been granted;

                  (vi) Notwithstanding any other provision in the Operative
     Documents, any Tranche B Lender may at any time create a security interest
     in, or pledge, all or any

                                      -80-
<PAGE>

     portion of its rights under and interest in any of the Operative Documents
     in favor of any Federal Reserve Bank in accordance with Regulation A of the
     Federal Reserve Board or U.S. Treasury Regulation 31 CFR 203.14, and such
     Federal Reserve Bank may enforce such pledge or security interest in any
     manner permitted under Applicable Law; and

                  (vii) Provided no Lease Event of Default has occurred and is
     continuing, on any Floating Payment Date after at least thirty (30) days,
     but no more than sixty (60) days advance written notice to each party
     hereto, Lessee may cause all, but not less than all Tranche B Lenders to
     sell with recourse, representation or warranties their rights and interests
     in the Tranche B Loans, to any financial institutions selected by Lessee
     for an amount equal to (A) the outstanding balance of such Person's Tranche
     B Loan plus (B) all interest accrued on such amount plus (C) any Breakage
     Costs suffered by such Person, plus (D) any other amount due such person
     under the Operative Documents (the "Tranche B Transfer Amount") provided
     such financial institution purchases from such Tranche B Lender (or any
     Affiliate thereof) any interest it or such Affiliate may have in Lessor for
     an amount equal to (A) the outstanding balance of such Person's Equity
     Contribution, plus (B) all Equity Yield accrued on such amount plus (C) any
     Breakage Costs suffered by such Person (the "Equity Transfer Amount"). Such
     sale or sales shall become effective upon delivery of an Assignment and
     Assumption Agreement and payment to each Tranche B Lender and, if
     applicable, Limited Partner in immediately available funds its respective
     Tranche B Transfer Amount or Equity Transfer Amount. Lessor agrees to amend
     the Applicable Tranche B Rates as such replacement Tranche B Lenders may
     agree.

         12.8. Execution and Effectiveness. This Agreement may be executed (i)
in multiple counterparts, each of which shall be regarded as an original and all
of which shall constitute a single instrument and shall become effective on the
Closing Date when each of the parties hereto shall have signed a copy hereof
(whether the same or different copies) and (ii) by facsimile signature and each
such signature shall be treated in all respects as having the same effect as an
original signature.

         12.9. Survival. Each of the representations, warranties, terms,
covenants, agreements and conditions contained in this Agreement shall
specifically survive the execution and delivery of this Agreement and the other
Operative Documents, the issuing of the Tranche A Notes and the making of the
Tranche B Loans and Equity Contributions and shall, unless otherwise expressly
provided therein, continue in full force and effect until the Tranche A Notes
and Tranche B Loans, together with interest thereon, the Equity Contributions
together with the Equity Yield and all other sums payable hereunder or
thereunder have been indefeasibly paid in full.

         12.10. Severability. The provisions of this Agreement are severable,
and if any section or provision shall be held invalid or unenforceable in whole
or in part in any jurisdiction, then such invalidity or unenforceability shall
affect only such clause or provision, or part thereof, in such jurisdiction and
shall not in any manner affect such clause or provision in any other
jurisdiction, or any other clause or provision of this Agreement in any
jurisdiction.

         12.11. No Broker. Each party hereto hereby represents and warrants to
the other parties that no broker other than Arranger (whose fees shall be paid
solely by Lessee) brought about the transactions contemplated hereby and each
party hereby agrees to indemnify (the "Indemnifying Party") and hold each other
party harmless from, any and all other liabilities and costs (including, without
limitation, costs of counsel) to any Person claiming brokerage commissions or
finder's fees as a result of any agreement with the Indemnifying Party.

         12.12. Limited Recourse Against Limited Partners and Lessor General
Partner. Without impairing any of the other rights, powers, privileges, liens or

under any of the Operative Documents, or any negligent mishandling of funds or
any failure to apply any amounts received from any party hereto in accordance
with the terms of the Operative Documents, (iv) prevent the bringing of an
action or obtaining a judgment over Lessor to obtain jurisdiction over the
Lessor Collateral, Lessee or Guarantor; provided that no judgment or any such
action shall seek a deficiency judgment against Lessor or hold Lessor General
Partner, any Limited Partner or any incorporator, shareholder, partner, officer,
director of Lessor General Partner or any Limited Partner personally liable
therefor, or (v) prevent the bringing of an action or obtaining of a judgment to
foreclose the lien of this Agreement or Security Documents or otherwise realize
upon the Lessor Collateral or the sums due or to

any amount is an Excepted Payment, Lessor, Lessee and Guarantor shall abide by
Administrative Agent's determination with respect to such amount.

Agreement, each of the parties hereto acknowledges receipt of and consents to

time to time, and includes all exhibits, supplements and appendices thereto.
Unless otherwise specified, any Person defined or referred to below includes its

meanings, controlled by and under common control with) such corporation or other
Person.

                  "After-Tax Basis" means in respect of an amount (the "base
amount") with respect to a Person, (i) the base amount supplemented by (ii) an
additional payment, if necessary, to such Person such that, after reduction (but
not below zero) for the net amount of all Taxes (taking into account credits,
offsets, deductions or other benefits realized or to be realized by such Person
or its Affiliates in respect of such base amount and such Taxes, calculated
assuming that such credits reduce such taxes, and any deductions or other
benefits reduce income that would otherwise be subject to such tax, at the
then-maximum marginal rate generally applicable to such Person), if any, imposed
on such Person (calculated at the then maximum marginal rates generally
applicable to such Person) in respect of the sum of the base amount and such
additional payment shall be equal to the base amount.

                  "Alternate Rate" means a variable rate equal to the greater of

and Deutsche Bank AG, New York Branch may make commercial loans or other loans
