ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.

         On July 22, 1998, Hanover Compressor Company (the "Company") completed
a $200 million, 5-year lease transaction arranged by Chase Securities Inc. The
transaction has been structured as a sale lease back of compression equipment to
Hanover Equipment Trust 1998A, a newly-formed Delaware business trust (the
"Trust"), unrelated to the Company, any of its affiliates or any of its officers
or directors. The equipment was sold to the Trust for $200 million, an amount as
determined by an independent appraisal. Under the lease transaction, the
compression equipment was sold to the Trust and leased back by the Company for a
5-year period and will continue to be deployed by the Company under its normal
operating procedures. Additionally, the Company has the option to repurchase the
equipment from the Trust at any time.

         Proceeds from the transaction will be used to repay borrowings under
the Company's existing $200 million revolving credit facility with The Chase
Manhattan Bank, as agent (the "Bank Credit Agreement"). At the completion of
this transaction, the Company will have $180 million of availability under the
Bank Credit Agreement to fund the Company's ongoing working capital requirements
and expansion plans.

         As a result of the transaction, the Company's annual depreciation
expense will decrease by approximately $7.5 million. The Company will incur
annual operating lease expense of approximately $14 million (or 7% of the $200
million sales proceeds), an amount which approximates the annual interest
expense of the Company's existing revolving credit debt that was repaid as a
result of the sale.

ITEM 7.           FINANCIAL STATEMENTS AND EXHIBITS.

                  (a) - (b) Not applicable.
                  (c) See Exhibit Index attached hereto and incorporated herein.

                  LEASE (this "Lease"), dated as of July 20, 1998, between
HANOVER EQUIPMENT TRUST 1998A, a Delaware business trust, having its principal
office at c/o Wilmington Trust Company, Rodney Square North, 1100 North Market

COMPRESSOR COMPANY a Delaware corporation, having its principal office at 12001
North Houston Rosslyn, Houston, Texas 77806, as lessee (the "Lessee").

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


                             SECTION 1. DEFINITIONS

                  1.1 Defined Terms. Capitalized terms used herein but not
otherwise defined in this Lease shall have the respective meanings specified in
Annex A to the Participation Agreement dated as of the date hereof among Lessee,
Lessor, Agent, the Investor and the Lenders named therein, as such Participation
Agreement may be amended, supplemented or otherwise modified from time to time.


                          SECTION 2. EQUIPMENT AND TERM

                  2.1 Equipment. Subject to the terms and conditions hereinafter
set forth and contained in the respective Lease Supplement relating to each
piece of Equipment, Lessor hereby leases to Lessee, and Lessee hereby leases
from Lessor, each piece of Equipment.

                  2.2 Lease Term. The Equipment is leased for the Term, unless
extended or earlier terminated in accordance with the provisions of this Lease.

                  2.3 Title. Except as otherwise expressly set forth in the

representation or warranty, express or implied, by Lessor and subject to the
rights of parties in possession, the existing state of title (including, without
limitation, the Permitted Exceptions) and all applicable Legal Requirements.
Lessee shall in no event have any recourse against Lessor for any defect in

of Lessor or its Affiliates. Lessor and Lessee hereby declare that it is their
mutual intent that the Equipment is to be considered movable (personal)
property, severable from the improvements in which it may be located, and not
immovables or components of immovables, for all purposes of this Lease.

                  2.4 Lease Supplements. On each Equipment Closing Date, Lessee

                                 SECTION 3. RENT

                  3.1 Rent. (a) On each applicable Payment Date after the
Equipment Closing Date with respect to a piece of Equipment, Lessee shall pay
the Basic Rent attributable to such Equipment.

                  (b) Basic Rent shall be due and payable in Dollars and shall
be paid by wire transfer of immediately available funds on the due date therefor
to such account or accounts at such bank or banks or to such other Person or in
such other manner as Lessor shall from time to time direct.

                  (c) Lessee's inability or failure to take possession of all,
or any piece, of the Equipment when delivered by Lessor shall not delay or
otherwise affect Lessee's obligation to pay Rent in accordance with the terms of
this Lease.

                  3.2 Supplemental Rent. Lessee shall pay to Lessor or the
Person entitled thereto any and all Supplemental Rent promptly as the same shall

Lessor as Supplemental Rent, among other things, on demand, to the extent
permitted by applicable Legal Requirements, interest at the applicable Overdue
Rate on any installment of Basic Rent not paid when due for the period for which
the same shall be overdue and on any payment of Supplemental Rent not paid when
due or demanded by Lessor for the period from the due date or the date of any
such demand, as the case may be, until the same shall be paid. The expiration or
other termination of Lessee's obligations to pay Basic Rent hereunder shall not
limit or modify the obligations of Lessee with respect to Supplemental Rent.
Unless expressly provided otherwise in this Lease or any other Operative
Agreement, in the event of any failure on the part of Lessee to pay and
discharge any Supplemental Rent as and when due, Lessee shall also promptly pay
and discharge any fine, penalty, interest or cost which may be assessed or added
for nonpayment or late payment of such Supplemental Rent, all of which shall
also constitute Supplemental Rent.

                  3.3 Performance on a Non-Business Day. If any payment is
required hereunder on a day that is not a Business Day, then such payment shall
be due on the next succeeding Business Day, unless, in the case of payments
based on the Eurodollar Rate, the result of such extension would be to extend
such payment into another calendar month, in which event such payment shall be
made on the immediately preceding Business Day.


                              SECTION 4. WARRANTIES

                  4.1 Warranties. Lessor agrees to take all such actions as may
be reasonably necessary to insure that Lessee is the beneficiary of any and all
warranties with respect to the Equipment, provided, however, the reasonable
costs of any such actions shall be borne by Lessee.

                           SECTION 5. QUIET ENJOYMENT

                  5.1 Quiet Enjoyment. So long as no Lease Event of Default
shall have occurred and be continuing, Lessee shall peaceably and quietly have,
hold and enjoy the Equipment for the Term, free of any claim or other action by
Lessor or anyone claiming by, through or under Lessor.


                              SECTION 6. NET LEASE

                  6.1 Net Lease; No Setoff; Etc. This Lease shall constitute a
net lease and, except as otherwise provided herein or in the other Operative
Agreements, it is intended that Basic Rent and Supplemental Rent shall be paid
without counterclaim, setoff, deduction or defense of any kind and without
abatement, suspension, deferment, diminution or reduction of any kind, and
Lessee's obligation to pay all such amounts is absolute and unconditional,
provided, that if at any time the Lessee is required to make a payment of (i)
Termination Value or (ii) an indemnity payment pursuant to Section 12 of the
Participation Agreement to the Investor, and there shall exist any Lessor Liens
attributable to the Investor (and the Lessee shall have previously incurred a
charge to discharge any Lessor Liens attributable to the Investor), then the
Lessee shall be entitled to deduct from the portion required to be paid to the
Investor of Termination Value or payment of indemnity, as the case may be, an
amount sufficient to so reimburse the Lessee for the cost of discharging such
Lessor Liens, as the case may be. The obligations and liabilities of Lessee
hereunder shall in no way be released, discharged or otherwise affected for any
reason, including, without limitation, to the maximum extent permitted by law:
(a) any defect in the condition, merchantability, design, quality or fitness for
use of any portion of any Equipment, or any failure of any Equipment to comply
with all Legal Requirements, including any inability to use any Equipment by
reason of such non-compliance; (b) any damage to, abandonment, loss,
contamination of or Release from or destruction of or any requisition or taking
of any Equipment or any part thereof; (c) any restriction, prevention or
curtailment of or interference with any use of any Equipment or any part
thereof; (d) any defect in title to or rights to any Equipment or any Lien on
such title or rights or on any Equipment; (e) any change, waiver, extension,
indulgence or other action or omission or breach in respect of any obligation or
liability of or by Lessor, Investor, Agent or any Lender; (f) any bankruptcy,
insolvency, reorganization, composition, adjustment, dissolution, liquidation or
other like proceedings relating to Lessee, Lessor, Investor, Agent, any Lender
or any other Person, or any action taken with respect to this Lease by any
trustee or receiver of Lessee, Lessor, Investor, Agent, any Lender or any other
Person, or by any court, in any such proceeding; (g) any claim that Lessee has
or might have against any Person, including, without limitation, Lessor,
Investor, Agent or any Lender; (h) any failure on the part of Lessor to perform
or comply with any of the terms of this Lease, any other Operative Agreement or
of any other agreement; (i) any invalidity or unenforceability or disaffirmance
against or by Lessee of this Lease or any provision hereof or any of the other
Operative Agreements or any provision of any thereof; (j) the impossibility of
performance by Lessee, Lessor or both; (k) any action by any court,
administrative agency or other Governmental Authority; any restriction,
prevention or curtailment of or any interference with the construction on or any
use of any Equipment or any part thereof; or

                                                                               4


(m) any other occurrence whatsoever, whether similar or dissimilar to the
foregoing, whether or not Lessee shall have notice or knowledge of any of the
foregoing. This Lease shall be noncancellable by Lessee for any reason
whatsoever except as expressly provided herein or in the other Operative
Agreements, and Lessee, to the extent permitted by Legal Requirements, waives
all rights now or hereafter conferred by statute or otherwise to quit, terminate
or surrender this Lease, or to any diminution, abatement or reduction of Rent
payable by Lessee hereunder. If for any reason whatsoever this Lease shall be
terminated in whole or in part by operation of law or otherwise, except as
otherwise expressly provided herein or in the other Operative Agreements, Lessee
shall, unless prohibited by Legal Requirements, nonetheless pay to Lessor (or,
in the case of Supplemental Rent, to whomever shall be entitled thereto) an
amount equal to each Rent payment at the time and in the manner that such
payment would have become due and payable under the terms of this Lease if it
had not been terminated in whole or in part, and in such case, so long as such
payments are made and no Lease Event of Default shall have occurred and be
continuing, Lessor will deem this Lease to have remained in effect. Each payment
of Rent made by Lessee hereunder shall be final and, absent manifest error in
the computation of the amount thereof, Lessee shall not seek or have any right
to recover all or any part of such payment from Lessor, Investor, Agent or any
party to any agreements related thereto for any reason whatsoever. Lessee
assumes the sole responsibility for the condition, use, operation, maintenance,
and management of the Equipment and Lessor shall have no responsibility in
respect thereof and shall have no liability for damage to the property of Lessee
or any subtenant of Lessee on any account or for any reason whatsoever other
than resulting from Lessor's gross negligence or wilful misconduct.

                  6.2 No Termination or Abatement. Lessee shall remain obligated
under this Lease in accordance with its terms and shall not take any action to
terminate, rescind or avoid this Lease, notwithstanding any action for
bankruptcy, insolvency, reorganization, liquidation, dissolution, or other
proceeding affecting Lessor, or any action with respect to this Lease which may
be taken by any trustee, receiver or liquidator of Lessor or by any court with
respect to Lessor, except as otherwise expressly provided herein. Lessee hereby
waives all right (i) to terminate or surrender this Lease, except as otherwise
expressly provided herein or in the other Operative Agreements, or (ii) to avail
itself of any abatement, suspension, deferment, reduction, setoff, counterclaim
or defense with respect to any Rent. Lessee shall remain obligated under this
Lease in accordance with its terms and, to the extent permitted by law, Lessee
hereby waives any and all rights now or hereafter conferred by statute or
otherwise to modify or to avoid strict compliance with its obligations under
this Lease. Notwithstanding any such statute or otherwise, to the extent
permitted by law, Lessee shall be bound by all of the terms and conditions
contained in this Lease.


                        SECTION 7. OWNERSHIP OF EQUIPMENT

                  7.1 Ownership of the Equipment. (a) Lessor and Lessee intend
that (i) for financial accounting purposes with respect to Lessee (A) this Lease
will be treated as an "operating lease" pursuant to Statement of Financial
Accounting Standards (SFAS) No. 13, as amended, (B) Lessor will be treated as
the owner and lessor of the Equipment and

<PAGE>   10

                                                                               5



(C) Lessee will be treated as the lessee of the Equipment, but (ii) for federal,
state and local income tax and state law purposes (A) this Lease will be treated
as a financing arrangement, (B) the Lenders will be treated as senior lenders
making loans to Lessee in an amount equal to the Loans, which Loans will be
secured by the Equipment, (C) Lessor will be treated as a subordinated lender
making a loan to Lessee in an amount equal to the Investor Contribution, which
loan is secured by the Equipment, and (D) Lessee will be treated as the owner of
the Equipment and will be entitled to all tax benefits ordinarily available to
an owner of property like the Equipment for such tax purposes.

                  (b) Lessor and Lessee further intend and agree that, for the
purpose of securing Lessee's obligations for the repayment of the
above-described loans, (i) this Lease shall also be a security agreement (as
defined in Section 1-201(37) of the Uniform Commercial Code) and financing
statement within the meaning of Article 9 of the Uniform Commercial Code; (ii)
the conveyance provided for in Section 2 shall be deemed a grant of a security
interest in Lessee's right, title and interest in the Equipment (including the
right to exercise all remedies as are contained herein upon the occurrence of a
Lease Event of Default) and all proceeds of the conversion, voluntary or
involuntary, of the foregoing into cash, investments, securities or other
property, whether in the form of cash, investments, securities or other
property, for the benefit of the Lessor to secure the Lessee's payment of all
amounts owed by the Lessee under this Lease and the other Operative Agreements
and Lessor holds title to the Equipment so as to create and grant a first lien
and prior security interest in the Equipment (A) pursuant to this Lease for the
benefit of the Agent under the Assignment of Lease, to secure to the Agent the
obligations of the Lessee under the Lease and (B) pursuant to the Security
Agreement to secure to the Agent the obligations of the Lessor under the Credit
Agreement and the Notes; (iii) the possession by Lessor or any of its agents of
notes and such other items of property as constitute instruments, money,
negotiable documents or chattel paper shall be deemed to be "possession by the
secured party" for purposes of perfecting the security interest pursuant to
Section 9-305 of the Uniform Commercial Code; and (iv) notifications to Persons
holding such property, and acknowledgements, receipts or confirmations from
financial intermediaries, bankers or agents (as applicable) of Lessee shall be
deemed to have been given for the purpose of perfecting such security interest
under applicable law. Lessor and Lessee shall take such actions as may be
necessary to ensure that such security interest is a perfected security interest
of first priority under applicable law and will be maintained as such throughout
the Term. Nevertheless, Lessee acknowledges and agrees that none of Lessor,
Investor, the Trust Company, Agent, or any Lender has provided or will provide
tax, accounting or legal advice to Lessee regarding this Lease, the Operative
Agreements or the transactions contemplated hereby and thereby, or made any
representations or warranties concerning the tax, accounting or legal
characteristics of the Operative Agreements, and that Lessee has obtained and
relied upon such tax, accounting and legal advice concerning the Operative
Agreements as it deems appropriate.

                  (c) Lessor and Lessee further intend and agree that in the
event of any insolvency or receivership proceedings or a petition under the
United States bankruptcy laws or any other applicable insolvency laws or statute
of the United States of America or any State or Commonwealth thereof affecting
Lessee or Lessor, the transactions evidenced by this Lease shall be regarded as
loans made by an unrelated third party lender to Lessee.

IRREVOCABLY RELEASES LESSOR, THE INVESTOR AND EACH OTHER PERSON PARTY TO THE
OPERATIVE AGREEMENTS, AND EACH OF THEIR EMPLOYEES, OFFICERS, DIRECTORS,
REPRESENTATIVES, AGENTS, SERVANTS, ATTORNEYS, AFFILIATES, PARENT COMPANIES,

LESSOR, THE INVESTOR OR ANY OTHER SUCH PERSON. THIS RELEASE INCLUDES CLAIMS OF
WHICH LESSEE IS PRESENTLY UNAWARE OR WHICH LESSEE DOES NOT PRESENTLY SUSPECT TO
EXIST WHICH, IF KNOWN BY LESSEE, WOULD MATERIALLY AFFECT LESSEE'S RELEASE OF
LESSOR AND THE OTHER PERSONS RELEASED HEREBY.

                  8.2 Possession and Use of the Equipment. Each piece of
Equipment shall be used by Lessee in a manner consistent with its intended
purpose and in accordance with its specification. Subject to the terms of
Section 13 relating to permitted contests, Lessee shall pay, or cause to be

Equipment. Lessee shall not commit or permit any waste of any Equipment or any
part thereof.


                              SECTION 9. COMPLIANCE

                  9.1 Compliance with Legal Requirements and Insurance
Requirements. Subject to the terms of Section 13 relating to permitted contests,
Lessee, at its sole cost and expense, shall, in all material respects, (a)
comply with all Legal Requirements (including all Environmental Laws) and
Insurance Requirements relating to each piece of Equipment, including the use,
construction, operation, maintenance, repair and restoration thereof, whether or
not compliance therewith shall require extraordinary changes in the Equipment or
interfere with the use and enjoyment of the Equipment, and (b) procure, maintain
and comply with all licenses, permits, orders, approvals, consents and other
authorizations required for the construction, renovation, use, repair,
maintenance and operation of each piece of Equipment.

                                                                               8


a Termination Notice with respect to such piece of Equipment pursuant to Section
16.1, if applicable, or, at Lessee's sole cost and expense, promptly and
diligently undertake any response, clean up, remedial or other action necessary
to remove, cleanup or remediate the Environmental Violation in accordance with

Lessor's written request therefor cause to be prepared by an environmental
consultant reasonably acceptable to Lessor a report describing the Environmental
Violation and the actions taken by Lessee (or its agents) in response to such
Environmental Violation, and a statement by the consultant that such
Environmental Violation has been remedied in full compliance with applicable
Environmental Laws. The foregoing provisions of this Section 9.2(a)
notwithstanding, Lessee shall not be required to deliver a Termination Notice if
such Environmental Violation would not reasonably be expected to have a material
adverse affect on the Equipment.

                  (b) In addition, Lessee shall provide to Lessor, within five
(5) Business Days of receipt, copies of all significant written communications
with any Governmental Authority relating to any Environmental Claim in

             SECTION 10. MAINTENANCE, REPAIR AND RETURN REQUIREMENTS

                  10.1 Maintenance and Repair. (a) Lessee shall, at its sole
cost and expense, (i) take good care of the Equipment and keep the same and all
parts thereof in good and safe order and condition, with all mechanical devices,
electronic systems and component parts in good working order, normal wear and
tear excepted, consistent with maintenance practices used by Lessee with respect

customary industry standards, and (ii) promptly make all needed repairs,
restorations and replacements of parts in and to the Equipment or any part
thereof, including, without limitation, overhaul of any piece of Equipment
requiring overhaul in Lessee's commercially prudent judgment. All such repairs,
restorations and replacements of parts shall be of a standard and quality
consistent with customary industry standards and sufficient for the proper
maintenance and operation of the Equipment and shall be constructed and
installed in a good and workmanlike manner in compliance with Legal Requirements
and Insurance Requirements. In carrying out its obligations under this Section
10.1, Lessee shall not discriminate in any way in the maintenance of the
Equipment as compared with other similar equipment owned or leased by Lessee and
shall use the Equipment in a manner consistent with sound operating practices
thereof.

                  (b) Lessor shall under no circumstances be required to furnish
any services or facilities with respect to the Equipment or make any repairs,
replacements, alterations or renewals of any nature or description to any
Equipment, make any expenditure whatsoever in connection with this Lease or
maintain any Equipment in any way except as otherwise provided in the Operating
Agreements. Lessor shall not be required to maintain, repair or rebuild all or
any part of any Equipment, and Lessee waives the right to (i) require Lessor

<PAGE>   14

                                                                               9


to maintain, repair, or rebuild all or any part of any Equipment, or (ii) make
repairs at the expense of Lessor pursuant to any Legal Requirement, Insurance
Requirement, contract, agreement, covenants, condition or restriction at any
time in effect.

                  10.2 Return Requirements. (a) Unless Lessee shall have
exercised its Purchase Option or Maturity Date Purchase Option, Lessee shall,
upon the expiration or earlier termination of the Term with respect to each
piece of Equipment, surrender and transfer such Equipment to Lessor, at Lessee's
own expense, free and clear of all Liens other than (A) the following items set
forth under the definition of Permitted Liens: (i), (ii), (viii) and (ix) and
(B) Lessor Liens, in as good condition as they were on the Equipment Closing
Date with respect to each piece of Equipment, ordinary wear and tear excepted,
and in compliance with all Legal Requirements and the other requirements of this
Lease, including, without limitation, Section 10.1 (and in any event without (x)
any asbestos installed or maintained in any part of such Equipment, (y) any
polychlorinated byphenyls (PCBs) in, on or used with respect to such Equipment,
and (z) any other Hazardous Substances). Unless Lessee has exercised the
Purchase Option or the Maturity Date Purchase Option, Lessee shall provide, or
cause to be provided or accomplished, at the sole cost and expense of Lessee, to
or for the benefit of Lessor or a purchaser, at least thirty Business Days prior
to the expiration or earlier termination of the Term with respect to each piece
of Equipment, each of the following: (i) a Lien search showing (A) no Liens
other than the type set forth as clauses (A) and (B) in the first sentence of
this Section 10.2(a) and (B) the Security Agreement as creating a valid and
perfected first security interest in the Equipment; (ii) an environmental
assessment for the Equipment satisfying the requirements set forth in Section
10.4 below; (iii) an assignment of all of the Lessee's right, title and interest
in and to each agreement executed by Lessee in connection with the renovation,
development, use, maintenance or operation of the Equipment (including all
warranty, performance, service and indemnity provisions); (iv) an assignment of
all permits, licenses, approvals and other authorizations from all Governmental
Authorities in connection with the operation and use of the Equipment; and (v)
copies of all books and records, with respect to the renovation, maintenance,
repair, operation or use of the Equipment. Lessee shall cooperate with any
independent purchaser of the Equipment in order to facilitate the ownership and
operation by such purchaser of the Equipment after such expiration or earlier
termination of the Term, including providing all books, reports and records
regarding the maintenance, repair and ownership of the Equipment and all data
and technical information relating thereto, granting or assigning all licenses
necessary for the operation and maintenance of the Equipment and cooperating in
seeking and obtaining all necessary licenses, permits and approvals of
Governmental Authorities. Lessee shall have also paid the total cost for the
completion of all Modifications commenced prior to such expiration or earlier
termination of the Term. The obligation of Lessee under this Section 10.2(a)
shall survive the expiration or termination of this Lease.

                  (b) Lessee, on the expiration or earlier termination of the
Term, if requested by Lessor, shall, at Lessee's sole cost and expense dismantle
and crate each piece of Equipment that Lessor shall designate and, at Lessee's
sole cost and expense transport such Equipment to a location designated by
Lessor.

                                                                              10



                  10.3 Right of Inspection and Location. (a) Lessor may, at
reasonable times and with reasonable prior notice and without interfering with
the operations of Lessee's customers, inspect and examine at its own cost and
expense (unless a Lease Event of Default exists, in which case the reasonable
out-of-pocket costs and expenses of Lessor shall be paid by Lessee), any piece
of Equipment. Lessee may accompany Lessor on any such inspections.

                  (b) Lessee shall furnish to Lessor not less than once every
six months during the Term, an Officer's Certificate, accurate in all material
respects, stating the location of each piece of Equipment, noting whether any
Equipment has been relocated and if so the correct address of the relocated
Equipment. Lessor shall have no duty to make any such inspection or inquiry and
shall not incur any liability or obligation by reason of not making any such
inspection or inquiry.

                  10.4 Environmental Inspection. Not less than six months prior
to the Maturity Date (unless Lessee has previously irrevocably exercised the
Maturity Date Purchase Option), and not more than thirty Business Days prior to
surrender of possession of a piece of Equipment, Lessor shall, at Lessee's sole
cost and expense, obtain a report by an environmental consultant selected by
Lessor certifying that each piece of Equipment (i) does not contain Hazardous
Substances under circumstances or in concentrations that would reasonably be
expected to result in a violation of or liability under any Environmental Law
and (ii) is in compliance with all Environmental Laws. If such is not the case
on either such date, then Lessee shall be deemed to have irrevocably exercised
the Maturity Date Purchase Option pursuant to Section 20.2.


                            SECTION 11. MODIFICATIONS

                  11.1 Modifications. (a) Lessee, at its sole cost and expense,
may at any time and from time to time make alterations, renovations,
improvements and additions to a piece of Equipment or any part thereof
(collectively, "Modifications"); provided, that: (i) except for any Modification
required to be made pursuant to a Legal Requirement or an Insurance Requirement,
no Modification, individually, or when aggregated with any other Modification
shall impair the value of such Equipment or the utility or useful life of such
Equipment from that which existed immediately prior to such Modification; (ii)
the Modification shall be performed in a timely manner and in a good and
workmanlike manner; (iii) Lessee shall comply with all Legal Requirements
(including all Environmental Laws) and Insurance Requirements applicable to the
Modification, including the obtaining of all permits, and the structural
integrity of such Equipment shall not be adversely affected; (iv) subject to the
terms of Section 13 relating to permitted contests, Lessee shall pay all costs
and expenses and discharge any Liens arising with respect to the Modification;
and (v) such Modifications shall comply with Section 10.1 and shall not change
the primary character of such Equipment or intended use of such Equipment. All
Modifications shall remain part of the Equipment and shall be subject to this
Lease, and title thereto shall immediately vest in Lessor.

                                                                              11



                  (b) Lessee shall notify Lessor of the undertaking of any
Modifications the cost of which is anticipated to exceed $500,000.

                  (c) Lessee shall not without the consent of Lessor (which
consent will not be unreasonably withheld or delayed) undertake any
Modifications to any piece of Equipment if such Modifications cannot, in the
reasonable judgement of Lessee, be completed on or prior to the date that is one

                                SECTION 12. TITLE

                  12.1 Warranty of Title. (a) Lessee agrees that, except as
otherwise provided herein (i.e. with respect to Lessor Liens) and subject to the
terms of Section 13 relating to permitted contests, Lessee shall not directly or
indirectly create or allow to remain, and shall promptly discharge at its sole
cost and expense, any Lien, defect, attachment, levy, title retention agreement
or claim upon any piece of Equipment or any Modifications or any Lien,
attachment, levy or claim with respect to the Rent or with respect to any
amounts held by the Agent pursuant to the Credit Agreement, other than Permitted
Liens and/or Lessor Liens. Lessee shall promptly notify Lessor in the event it
has actual knowledge that a Lien (other than a Permitted Lien and/or a Lessor
Lien) exists with respect to the Equipment.

                  (b) Nothing contained in this Lease shall be construed as
constituting the consent or request of Lessor, expressed or implied, to or for
the performance by any contractor, mechanic, laborer, materialman, supplier or
vendor of any labor or services or for the furnishing of any materials for any
alteration, addition, repair or demolition of or to any piece of Equipment or
any part thereof. NOTICE IS HEREBY GIVEN THAT LESSOR IS NOT AND SHALL NOT BE
LIABLE FOR ANY LABOR, SERVICES OR MATERIALS FURNISHED OR TO BE FURNISHED TO
LESSEE, OR TO ANYONE HOLDING ANY EQUIPMENT OR ANY PART THEREOF THROUGH OR UNDER
LESSEE, AND THAT NO MECHANIC'S OR OTHER LIENS FOR ANY SUCH LABOR, SERVICES OR
MATERIALS SHALL ATTACH TO OR AFFECT THE INTEREST OF LESSOR IN AND TO ANY
EQUIPMENT.

                  12.2 Identification. Lessee shall not allow the name of any
Person to be placed upon any portion of any piece of Equipment as a designation
that might be interpreted as indicating a claim of ownership thereof or security
interest therein by any Person other than Lessee.


                         SECTION 13. PERMITTED CONTESTS

                  13.1 Permitted Contests Other Than in Respect of Impositions.

                                                                              12


on its own or on Lessor's behalf but at Lessee's sole cost and expense, may
contest, by appropriate administrative or judicial proceedings conducted in good
faith and with due diligence, the amount, validity or application, in whole or
in part, of any Legal Requirement, or any Lien, attachment, levy, encumbrance or
encroachment, and Lessor agrees not to pay, settle or otherwise compromise any
such item, provided that (a) the commencement and continuation of such
proceedings shall suspend the collection thereof from, and suspend the
enforcement thereof against the applicable Equipment, Lessor, the Agent, the
Investor and the Lenders; (b) there shall be no risk of the imposition of a Lien
(other than a Permitted Lien) on any piece of Equipment and no part of any piece
of Equipment nor any Rent would be in any danger of being sold, forfeited, lost
or deferred; (c) at no time during the permitted contest shall there be a risk
of the imposition of criminal liability or civil liability on Lessor, the Agent
or any Lender for failure to comply therewith; and (d) in the event that, at any
time, there shall be a material risk of extending the application of such item
beyond the earlier of the Maturity Date and the Expiration Date for the
applicable Equipment, then Lessee shall deliver to Lessor an Officer's
Certificate certifying as to the matters set forth in clauses (a), (b) and (c)
of this Section 13.1. Lessor, at Lessee's sole cost and expense, shall execute
and deliver to Lessee such authorizations and other documents as may reasonably
be required in connection with any such contest and, if reasonably requested by
Lessee, shall join as a party therein at Lessee's sole cost and expense.


                              SECTION 14. INSURANCE

                  14.1 Public Liability and Workers' Compensation Insurance.
During the Term, Lessee shall procure and carry, at Lessee's sole cost and
expense, commercial general liability insurance for claims for injuries or death
sustained by persons or damage with respect to the use or operation of the
Equipment. Such insurance shall be on terms and in amounts that are no less
favorable than insurance maintained by owners of similar equipment which are in
Lessee's line of business, that are in accordance with normal industry practice.
The policy shall be endorsed to name Lessor, the Trust Company, the Investor,
the Agent and the Lenders as additional insureds. The policy shall also
specifically provide that the policy shall be considered primary insurance which
shall apply to any loss or claim before any contribution by any insurance which
Lessor, the Trust Company, the Agent or the Lenders may have in force. Lessee
shall, in the operation of the Equipment, comply with the applicable workers'
compensation laws and protect Lessor against any liability under such laws.

                  14.2 Hazard and Other Insurance. During the Term, Lessee shall
keep each piece of Equipment insured against loss or damage by fire and other
risks on terms and in amounts that are no less favorable than insurance
maintained by owners of similar equipment, that are in accordance with normal
industry practice, are in amounts equal to the greater of (i) Termination Value
and (ii) the actual replacement cost of the Equipment. So long as no Lease Event
of Default exists, any loss payable under the insurance policy required by this
Section will be paid to and adjusted solely by Lessee, subject to Section 15.



<PAGE>   18

                                                                              13


                  14.3 Coverage. (a) Lessee shall furnish Lessor with
certificates showing the insurance required under Sections 14.1 and 14.2 to be
in effect and naming Agent, the Lenders, the Lessor, the Investor, and the Trust
Company as an additional insured with respect to liability insurance and showing
the endorsement required by Section 14.3(c). All such insurance shall be at the
cost and expense of Lessee. Such certificates shall include a provision in which
the insurer agrees to provide thirty (30) days' advance written notice by the
insurer to Lessor and the Agent in the event of cancellation or modification of
such insurance that would reasonably be expected to be adverse to the interests
of Lessor, the Trust Company or the Agent. If a Lease Event of Default has
occurred and is continuing and Lessor so requests, Lessee shall deliver to
Lessor copies of all insurance policies required by this Lease.

                  (b) Lessee agrees that the insurance policy or policies
required by this Lease shall include an appropriate clause pursuant to which
such policy shall provide that it will not be invalidated should Lessee waive,
in writing, prior to a loss, any or all rights of recovery against any party for
losses covered by such policy. Lessee hereby waives any and all such rights
against Lessor, the Trust Company, the Investor, the Agent and the Lenders to
the extent of payments made under such policies.

                  (c) All insurance policies required by Section 14.2 shall
include a loss payee endorsement in favor of the Agent.

                  (d) Neither Lessor nor Lessee shall carry separate insurance
concurrent in kind or form or contributing in the event of loss with any
insurance required under this Lease except that Lessor may carry separate
liability insurance so long as (i) Lessee's insurance is designated as primary
and in no event excess or contributory to any insurance Lessor may have in force
which would apply to a loss covered under Lessee's policy and (ii) each such
insurance policy will not cause Lessee's insurance required under this Lease to
be subject to a coinsurance exception of any kind.

                  (e) Lessee shall pay as they become due all premiums for the
insurance required by this Lease, shall renew or replace each policy prior to
the expiration date thereof and shall promptly deliver to Lessor and the Agent
certificates for renewal and replacement policies.


                      SECTION 15. CONDEMNATION AND CASUALTY

                  15.1 Casualty and Condemnation. (a) Subject to the provisions
of this Section 15 and Section 16 (in the event Lessee delivers, or is obligated
to deliver, a Termination Notice), and prior to the occurrence and continuation
of a Lease Event of Default, Lessee shall be entitled to receive (and Lessor
hereby irrevocably assigns to Lessee all of Lessor's right, title and interest
in) any award, compensation or insurance proceeds to which Lessee or Lessor may
become entitled by reason of their respective interests in the Equipment (i) if
all or a portion of such Equipment is damaged or destroyed in whole or in part
by a Casualty or (ii) if the use, access, easement rights or title to such
Equipment or any part thereof is the subject of a Condemnation; provided,
however, if a Lease Event of

                                                                              14

Default shall have occurred and be continuing such award, compensation or
insurance proceeds shall be paid directly to Lessor or, if received by Lessee,
shall be held in trust for Lessor, and shall be paid over by Lessee to Lessor.

                  (b) So long as no Lease Event of Default has occurred and is
continuing, Lessee may appear in any proceeding or action to negotiate,
prosecute, adjust or appeal any claim for any award, compensation or insurance
payment on account of any such Casualty or Condemnation and shall pay all
expenses thereof. At Lessee's reasonable request, and at Lessee's sole cost and
expense, Lessor and the Agent shall participate in any such proceeding, action,
negotiation, prosecution or adjustment. Lessor and Lessee agree that this Lease
shall control the rights of Lessor and Lessee in and to any such award,
compensation or insurance payment.

                  (c) If Lessor or Lessee shall receive notice of a Casualty or
a possible Condemnation of a piece of Equipment or any interest therein, Lessor
or Lessee, as the case may be, shall give notice thereof to the other and to the
Agent promptly after the receipt of such notice.

                  (d) In the event of a Casualty or receipt of notice by Lessee
or Lessor of a Condemnation, Lessee shall, not later than thirty (30) days after
such occurrence, deliver to Lessor and the Agent an Officer's Certificate
stating that either (i) (x) such Casualty is not a Significant Casualty or (y)
such Condemnation is neither a Total Condemnation nor a Significant Condemnation
and that this Lease shall remain in full force and effect with respect to the
applicable piece of Equipment and, at Lessee's sole cost and expense, Lessee
shall promptly and diligently restore the applicable piece of Equipment in
accordance with the terms of Section 15.1(e) or (ii) this Lease shall terminate
with respect to the applicable Equipment in accordance with Section 16.1.

                  (e) If pursuant to this Section 15.1, this Lease shall
continue in full force and effect following a Casualty or Condemnation with
respect to the affected piece of Equipment, Lessee shall, at its sole cost and
expense, promptly and diligently repair any damage to the applicable piece of
Equipment caused by such Casualty or Condemnation in conformity with the
requirements of Sections 10.1 and 11.1 so as to restore the applicable piece of
Equipment to the same condition, operation, function and value as existed
immediately prior to such Casualty or Condemnation. In such event, title to the
applicable piece of Equipment shall remain with Lessor.

                  (f) In no event shall a Casualty or Condemnation with respect
to which this Lease remains in full force and effect under this Section 15.1
affect Lessee's obligations to pay Rent pursuant to Section 3.1.

                  (g) Notwithstanding anything to the contrary set forth in
Section 15.1(a) or Section 15.1(e), if during the Term a Casualty occurs with
respect to a piece of Equipment or Lessee receives notice of a Condemnation with
respect to a piece of Equipment, and following such Casualty or Condemnation,
such piece of Equipment cannot reasonably be restored on or before the date
which is six months prior to the Maturity Date to substantially the same
condition as existed immediately prior to such Casualty or 

<PAGE>   20
                                                                              15


Condemnation or before such day such piece of Equipment is not in fact so
restored, then Lessee shall exercise its Purchase Option with respect to such
piece of Equipment, on the next Payment Date or irrevocably agree in writing to
exercise the Maturity Date Purchase Option with respect to such piece of
Equipment and in either such event such remaining Casualty or Condemnation
proceeds shall be paid to the Agent, which shall pay such funds to Lessee upon
the closing of the purchase of such piece of Equipment.


                          SECTION 16. LEASE TERMINATION

                  16.1 Termination upon Certain Events. (a) If Lessor or Lessee
shall have received notice of a Total Condemnation, then Lessee shall be
obligated, within thirty (30) days after Lessee receives notice thereof, to
deliver a written notice in the form described in Section 16.2(a) (a
"Termination Notice") of the termination of this Lease with respect to the
applicable piece of Equipment.

         and such default shall continue unremedied for a period of 30 days or
         any representation or warranty by Lessee or any Guarantor,
         respectively, set forth in this Lease, the Guarantee or in any other

<PAGE>   22

                                                                              17


request and cost, an assignment of Lessor's right, title and interest in the
Equipment, in each case in conformity with local custom and free and clear of
the Lien of the Security Agreement and any Lessor Liens. The Equipment shall be
quitclaimed to Lessee (or Lessee's designee) "AS IS" and in its then present
physical condition. If any statute or rule of law shall limit the amount of such
final liquidated damages to less than the amount agreed upon, Lessor shall be
entitled to the maximum amount allowable under such statute or rule of law.

                  17.3 Remedies. If any Lease Event of Default shall have
occurred and be continuing, Lessor may exercise in any order one or more or all
of the remedies set forth in this Section 17.3 (it being understood that no
remedy herein conferred is intended to be exclusive of any other remedy or
remedies, but each and every remedy shall be cumulative and shall be in addition
to every other remedy given herein or now or hereafter existing at law or in
equity or by statute).

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

                  (b) Lessor may by notice in writing to Lessee terminate this
         Lease but Lessee shall remain liable as hereinafter provided; and
         Lessor may, at its option, do any one or more of the following: (i)
         declare the Termination Value, plus all other amounts owing in respect
         of Rent or Supplemental Rent theretofore accruing under the Lease, all
         other amounts then payable by Lessee under this Lease and the other
         Operative Agreements to be immediately due and payable, and recover any
         other damages and expenses in addition thereto which Lessor shall have
         sustained by reason of such Event of Default; (ii) enforce the security
         interest given hereunder pursuant to the Uniform Commercial Code as
         provided in Section 28 or any other law; (iii) enter upon the premises
         where the Equipment is located and take possession of it; and (iv)
         require Lessee to return the Equipment as provided in Section 10.2; or

                  (c) Lessor may require Lessee immediately to purchase the
         Equipment for a purchase price equal to the sum of the Termination
         Value, plus all other amounts owing in respect of Rent or Supplemental
         Rent theretofore accruing under the Lease and all other amounts then
         due and payable under the Operative Agreements.

                  17.4 Additional Remedies. In addition to the remedies set
forth in Sections 17.2 and 17.3, if any Lease Event of Default shall have
occurred and be continuing, Lessor may, but is not required to, sell the
Equipment in one or more sales, and Lessor may purchase all or any part of the
Equipment at such sale. Lessee acknowledges that sales for cash or on credit to
a wholesaler, retailer or user of such Equipment, at a public or private
auction, are all commercially reasonable. Any notice required by law of intended
disposition by Lessor shall be deemed reasonable and properly given if given at
least ten (10) Business Days before such disposition.

                                                                              18



                  17.5 Proceeds of Sale; Deficiency. All payments received and
amounts held or realized by the Lessor at any time when a Lease Event of Default
shall have occurred and be continuing and after the Termination Value shall have
been accelerated pursuant to Section 17.2 or 17.3 as well as all payments or
amounts then held or thereafter received by Lessor shall be conveyed to the
Agent as required by the Assignment of Lease and distributed pursuant to Section
8.2 of the Credit Agreement.

                  17.6 Waiver of Certain Rights. If this Lease shall be
terminated pursuant to Section 17.1, Lessee waives, to the fullest extent
permitted by law, (a) any notice of re-entry or the institution of legal
proceedings to obtain re-entry or possession; (b) any right of redemption,
re-entry or repossession; (c) the benefit of any laws now or hereafter in force
exempting property from liability for rent or for debt; and (d) any other rights
which might otherwise limit or modify any of Lessor's rights or remedies under
this Section 17.

                  17.7 Assignment of Rights Under Contracts. If a Lease Event of
Default shall have occurred and be continuing, and whether or not this Lease
shall have been terminated pursuant to Section 17.1 and provided that Lessee
shall not have purchased the Equipment pursuant to Section 20, Lessee shall upon
Lessor's demand immediately assign, transfer and set over to Lessor, to the
extent transferable, all of Lessee's right, title and interest in and to each
agreement executed by Lessee in connection with the use or operation of the
Equipment (including all right, title and interest of Lessee with respect to all
warranty, performance, service and indemnity provisions), as and to the extent
that the same relate to the use, maintenance or operation of the Equipment.


                       SECTION 18. LESSOR'S RIGHT TO CURE

                  18.1 Lessor's Right to Cure Lessee's Lease Defaults. Lessor,
without waiving or releasing any obligation or Lease Event of Default, may (but
shall be under no obligation to) remedy any Lease Event of Default for the
account and at the sole cost and expense of Lessee, including the failure by
Lessee to maintain any insurance required by Section 14, and may, to the fullest
extent permitted by law, and notwithstanding any right of quiet enjoyment in
favor of Lessee, enter upon the premises where the Equipment is located for such
purpose and take all such action thereon as may be necessary or appropriate
therefor. No such entry shall be deemed an eviction of Lessee. All reasonable
out-of-pocket costs and expenses so incurred (including the reasonable fees and
expenses of counsel), together with interest thereon at the Overdue Rate from
the date on which such sums or expenses are paid by Lessor, shall be paid by
Lessee to Lessor on demand as Supplemental Rent.


                          SECTION 19. LEASE TERMINATION

                  19.1 Provisions Relating to Lessee's Termination of this Lease

         designee) at Lessee's cost and expense an assignment of Lessor's entire
         interest in the applicable Equipment, in each case in recordable form
         and otherwise in conformity with local custom and free and clear of the
         Lien of the Security Agreement and any Lessor Liens; and

                  (b) The applicable Equipment shall be conveyed to Lessee "AS
         IS" and in then present physical condition.

                  19.2 Aggregate Tranche A Percentage. Notwithstanding any other
provision of this Lease or the other Operative Agreements, the Lessee shall not
be permitted to terminate this Lease with respect to a piece of Equipment
pursuant to Section 16 or exercise its Purchase Option with respect to a piece
of Equipment pursuant to Section 20.1 if the Aggregate Tranche A Percentage,
after giving effect to the termination of this Lease with respect to such piece
of Equipment would be less than 85% or more than 89.9%.


                           SECTION 20. PURCHASE OPTION

                  20.1 Purchase Option. Lessee shall have the option
(exercisable by giving Lessor irrevocable written notice (the "Purchase Notice")
of Lessee's election, to exercise such option not less than ten (10) days prior
to the date of purchase pursuant to such option) to purchase one or more of the
pieces of Equipment on the date specified in such Purchase Notice, which date
must occur prior to the date which is six months prior to the Maturity Date, at
a price equal to the Termination Value (the "Purchase Option Price") (which the
parties do not intend to be a "bargain" purchase price) of such piece of
Equipment; provided, however, that Lessee shall only have such option with
respect to less than all of the Equipment if no Lease Default or Lease Event of
Default shall have occurred and be continuing. If Lessee exercises its option to
purchase one or more of the pieces of Equipment pursuant to this Section 20.1
(the "Purchase Option"), Lessor shall transfer to Lessee or Lessee's designee
all of Lessor's right, title and interest in and to such piece of Equipment as
of the date specified in the Purchase Notice upon receipt of the Purchase Option
Price and all Rent and other amounts then due and payable under this Lease and
any other Operative Agreement, in accordance with Section 19.1. Notwithstanding
the foregoing, (A) Lessee on not less than three (3) days prior notice may
exercise the Purchase Option to purchase one or more pieces of Equipment if the
purchase of such Equipment will cure an Event of Default and (B) if the Houston
Pipeline Purchase Option or a purchase option held by a sublessee or licensee of
a piece of Equipment has been exercised, then Lessee may exercise the Purchase
Option with respect to such piece of Equipment even if a Lease Default or Lease
Event of Default has occurred.

                  20.2 Maturity Date Purchase Option. Not less than six months
prior to the Maturity Date, Lessee may give Lessor and Agent irrevocable written
notice (the "Maturity





<PAGE>   25
                                                                              20


Date Election Notice") that Lessee is electing to exercise the Maturity Date
Purchase Option. If Lessee does not give a Maturity Date Election Notice on or
before the date six months prior to the Maturity Date or if Lessee has not
exercised the Purchase Option with respect to all of the Equipment, then Lessee
shall be obligated to remarket the Equipment pursuant to Section 21. If Lessee
has elected to exercise the Maturity Date Purchase Option, then on the Maturity
Date Lessee shall pay to Lessor an amount equal to the Termination Value for all
the Equipment (which the parties do not intend to be a "bargain" purchase price)
and, upon receipt of such amount plus all Rent and other amounts then due and
payable under this Lease and any other Operative Agreement, Lessor shall
transfer to Lessee or Lessee's designee all of Lessor's right, title and
interest in and to the Equipment in accordance with Section 19.1.

                  20.3 Obligation to Purchase All Equipment. If six months prior
to the Maturity Date, the then Termination Value of all the Equipment is less
than the Maximum Purchase Option Amount, then on the Maturity Date Lessee shall
be required to exercise its Maturity Date Purchase Option on the Maturity Date
with respect to all remaining Equipment.

                          SECTION 21. SALE OF EQUIPMENT

                  21.1 Sale Procedure. (a) With respect to each piece of
Equipment, unless Lessee shall have elected to purchase such Equipment and has
paid the relevant purchase price pursuant to Section 20.1 or 20.2 with respect
thereto, or otherwise terminated this Lease with respect thereto and paid the
Termination Value with respect thereto, Lessee shall (i) pay to Lessor the
Maximum Residual Guarantee Amount for such piece of Equipment as provided for in
Section 21.1(c), and (ii) sell such piece of Equipment, to one or more third
parties for cash in accordance with Section 21.1(b).

                  (b) During the Marketing Period, Lessee, as nonexclusive
broker for Lessor, shall use its best efforts to obtain bids for the cash
purchase of each piece of Equipment, being sold for the highest price available
in the relevant market, shall notify Lessor promptly of the name and address of
each prospective purchaser and the cash price which each prospective purchaser
shall have offered to pay for such piece of Equipment and shall provide Lessor
with such additional information about the bids and the bid solicitation
procedure as Lessor may reasonably request from time to time. Lessor may reject
any and all bids and may assume sole responsibility for obtaining bids by giving
Lessee written notice to that effect; provided, however, that notwithstanding
the foregoing, Lessor may not reject a bid if such bid, together with any
amounts to be paid pursuant to Section 21.3, is greater than or equal to the sum
of the Limited Deficiency Amount and all costs and expenses referred to in
Section 21.2(i) and is a bona fide offer by a third party purchaser who is not
an Affiliate of Lessee. If the price which a prospective purchaser shall have
offered to pay for all or any of the Equipment is less than the sum of the
Limited Deficiency Amount and all costs and expenses referred to in Section
21.2(i), Lessor may elect to retain the Equipment by giving Lessee at least two
Business Days' prior written notice of Lessor's election to retain the
Equipment, and upon receipt of such notice, Lessee shall surrender the Equipment
to Lessor pursuant to Section 10.2. Unless Lessor shall have elected to retain
the Equipment pursuant to the preceding sentence, following the 


<PAGE>   26

                                                                              21


Maturity Date Lessor shall sell the Equipment free of any Lessor Liens
attributable to it, without recourse or warranty, for cash to the purchaser or
purchasers identified by Lessee or Lessor, as the case may be. Lessee shall
surrender the Equipment so sold to each purchaser in the condition specified in
Section 10.2.

                  (c) On each date during the Marketing Period on which a piece
of Equipment is sold pursuant to Section 21.1(b), and on the Maturity Date with
respect to any Equipment remaining unsold, Lessee shall pay to Lessor the
Maximum Residual Guarantee Amount for such Equipment.

                  21.2 Application of Proceeds of Sale. Lessor shall apply the
proceeds of sale of each piece of Equipment in the following order of priority:

                       (i) FIRST, to pay or to reimburse Lessor and Lessee for
         the payment of all reasonable costs and expenses incurred by Lessor and
         Lessee in connection with the sale; and

                      (ii) SECOND, the balance shall be paid to the Agent to be
         applied pursuant to the provisions of Section 8 of the Credit
         Agreement.

                  21.3 Indemnity for Excessive Wear. If the proceeds of the sale
described in Section 21.1(b) with respect to any piece of Equipment, less all
expenses incurred by Lessor or Lessee in connection with such sale, shall be
less than the Limited Deficiency Amount for such piece of Equipment at the time
of such sale and if it shall have been determined (pursuant to the Appraisal
Procedure) that the Fair Market Sales Value of such piece of Equipment shall
have been impaired by greater than expected wear and tear during the Term,
Lessee shall pay to Lessor within ten (10) days after receipt of Lessor's
written statement (i) the amount of such excess wear and tear determined by the
Appraisal Procedure or (ii) the amount of the Net Sale Proceeds Shortfall,
whichever amount is less; provided that such Wear and Tear Payments shall not
prevent Lessee from accounting for this Lease as an operating lease under SFAS
NO. 13.

                  21.4 Appraisal Procedure. For determining the Fair Market
Sales Value of a piece of Equipment or any other amount which may, pursuant to
any provision of any Operative Agreement, be determined by an appraisal
procedure but with respect to which no appraisal or valuation method is
specified, Lessor and Lessee shall use the following procedure (the "Appraisal
Procedure"). Lessor and Lessee shall endeavor to reach a mutual agreement as to
such amount for a period of ten (10) days from commencement of the Appraisal
Procedure, and if they cannot agree within ten (10) days, then two qualified
appraisers, one chosen by Lessee and one chosen by Lessor, shall mutually agree
thereupon, but if either party shall fail to choose an appraiser within twenty
(20) days after notice from the other party of the selection of its appraiser,
then the appraisal by such appointed appraiser shall be binding on Lessee and
Lessor. If the two appraisers cannot agree within twenty (20) days after both
shall have been appointed, then a third appraiser from a nationally recognized
independent appraisal firm (with at least 15 years of experience appraising
equipment similar to and used in the same industry as the Equipment) shall be
selected by the two appraisers or, failing agreement as to such third appraiser
within thirty 

<PAGE>   27

                                                                              22


(30) days after both shall have been appointed, by the American Arbitration
Association. The decisions of the three appraisers shall be given within twenty
(20) days of the appointment of the third appraiser and the decision of the
appraiser most different from the average of the other two shall be discarded
and such average shall be binding on Lessor and Lessee; provided that if the
highest appraisal and the lowest appraisal are equidistant from the third
appraisal, the third appraisal shall be binding on Lessor and Lessee. The fees
and expenses of all of the appraisers shall be paid by the Lessee.

                  21.5 Certain Obligations Continue. During the Marketing
Period, the obligation of Lessee to pay Rent with respect to each piece of
Equipment (including the installment of Basic Rent due on the Maturity Date)
shall continue undiminished until payment in full to Lessor of the sale
proceeds, the Maximum Residual Guarantee Amount, if any, the amount due under
Section 21.3, if any, and all other amounts due to Lessor with respect to the
piece of Equipment. Lessor shall have the right, but shall be under no duty, to
solicit bids, to inquire into the efforts of Lessee to obtain bids or otherwise
to take action in connection with any such sale, other than as expressly
provided in this Section 21.


                            SECTION 22. HOLDING OVER

                  22.1 Holding Over. If Lessee shall for any reason remain in
possession of a piece of Equipment after the expiration or earlier termination
of this Lease (unless the piece of Equipment is conveyed to Lessee), such
possession shall be as a tenancy at sufferance during which time Lessee shall
continue to pay Supplemental Rent that would be payable by Lessee hereunder were
the Lease then in full force and effect with respect to such piece of Equipment
and Lessee shall continue to pay Basic Rent at an annual rate equal to the rate
payable hereunder immediately preceding such expiration or earlier termination;
provided, however, that from and after the sixtieth (60th) day Lessee shall
remain in possession of such piece of Equipment after such expiration or earlier
termination, Lessee shall pay Basic Rent at an annual rate equal to two hundred
percent (200%) of the Basic Rent payable hereunder immediately preceding such
expiration or earlier termination. Such Basic Rent shall be payable from time to
time upon demand by Lessor. During any period of tenancy at sufferance, Lessee
shall, subject to the second preceding sentence, be obligated to perform and
observe all of the terms, covenants and conditions of this Lease, but shall have
no rights hereunder other than the right, to the extent given by law to tenants
at sufferance, to continue its occupancy and use of the piece of Equipment.
Nothing contained in this Section 22 shall constitute the consent, express or
implied, of Lessor to the holding over of Lessee after the expiration or earlier
termination of this Lease as to any piece of Equipment and nothing contained
herein shall be read or construed as preventing Lessor from maintaining a suit
for possession of any piece of Equipment or exercising any other remedy
available to Lessor at law or in equity.


                            SECTION 23. RISK OF LOSS

                  23.1 Risk of Loss. The risk of loss of or decrease in the
enjoyment and beneficial use of the Equipment as a result of the damage or
destruction thereof by fire, the

                                                                              23


elements, casualties, thefts, riots, wars or otherwise is assumed by Lessee, and
Lessor shall in no event be answerable or accountable therefor (except
specifically with respect to its gross negligence or wilful misconduct).


                      SECTION 24. SUBLETTING AND ASSIGNMENT

                  24.1 Subletting and Assignment. Lessee may not assign this
Lease or any of its rights or obligations hereunder in whole or in part other
than as permitted by the Operative Agreements. Lessee may, without the consent
of Lessor, sublease or license the Equipment or any piece of Equipment to any
Person; provided that as of the Expiration Date no sublease or license shall
provide for a purchase option on behalf of the sublessee or licensee nor have a
remaining term of more than six months. No sublease, license or other
relinquishment of possession of the Equipment shall in any way discharge or
diminish any of Lessee's obligations to Lessor hereunder and Lessee shall remain
directly and primarily liable under this Lease as to the Equipment so sublet or
licensed.

                  24.2 Subleases or Licenses. Promptly following the execution
and delivery of any sublease or license permitted by this Section 24, Lessee
shall deliver an executed copy thereof to Lessor and the Agent if requested by
either.


                        SECTION 25. ESTOPPEL CERTIFICATES

                  25.1 Estoppel Certificates. At any time and from time to time
upon not less than twenty (20) days' prior request by Lessor, the Lessee shall
furnish to the Lessor a certificate signed by an individual having the office of
vice president or higher with Lessee certifying to the extent accurate that this
Lease is in full force and effect (or that this Lease is in full force and
effect as modified and setting forth the modifications); the dates to which the
Basic Rent and Supplemental Rent have been paid; to the best knowledge of the
signer of such certificate, whether or not the Lessor is in default under any of
its obligations hereunder (and, if so, the nature of such alleged default); and
such other matters under this Lease as the Lessor may reasonably request. Any
such certificate furnished pursuant to this Section 25 may be relied upon by the
Lessor, and any existing or prospective purchaser or lender, and any accountant
or auditor, of, from or to the Lessor (or any Affiliate thereof).


                              SECTION 26. NO WAIVER

                  26.1 No Waiver. No failure by Lessor or Lessee to insist upon
the strict performance of any term hereof or to exercise any right, power or
remedy upon a default hereunder, and no acceptance of full or partial payment of
Rent during the continuance of any such default, shall constitute a waiver of
any such default or of any such term. To the fullest extent permitted by law, no
waiver of any default shall affect or alter this Lease, and this Lease shall
continue in full force and effect with respect to any other then existing or
subsequent default.

                                                                              24

                       SECTION 27. ACCEPTANCE OF SURRENDER

                27.1 Acceptance of Surrender. (a) As of the Expiration Date,
if any Lease Default shall have occurred and be continuing under the Lease or
the representations and warranties set forth in Section 7.5(h)-(m) of the
Participation Agreement shall not be true and correct in any material respects,
then Lessee shall be deemed to have irrevocably exercised the Maturity Date
Purchase Option pursuant to Section 20.2.

                  (b) Except as otherwise expressly provided in this Lease, no
surrender to Lessor of this Lease or of all or any portion of the Equipment or
of any interest therein shall be valid or effective unless agreed to and
accepted in writing by Lessor and, prior to the payment or performance of all
obligations under the Credit Documents, the Agent, and no act by Lessor or the
Agent or any representative or agent of Lessor or the Agent, other than a
written acceptance, shall constitute an acceptance of any such surrender.


                    SECTION 28. OWNERSHIP, GRANT OF SECURITY
                         INTEREST AND FURTHER ASSURANCES

                  28.1 Grant of Security Interest. Other than Equipment
purchased by Lessee pursuant to Section 20, title to the equipment shall remain
in Lessor as security for the obligations of the Guarantors under the Guarantee
and the obligations of Lessee hereunder and under each of the other Operative
Agreements to which it is a party, until such time as Lessee and the Guarantors
have fulfilled all of their obligations hereunder and under such other Operative
Agreements. Lessee hereby assigns, grants and pledges to Lessor for the benefit
of Lessor a security interest in all of Lessee's right, title and interest,
whether now or hereafter existing or acquired, in (A) the Equipment (other than
Equipment purchased by Lessee pursuant to Section 20) and (B) any proceeds in
connection with the Houston Pipeline Purchase Option, to secure the payment and
performance of all obligations of Lessee now or hereafter existing under this
Lease or any other Operative Agreement and of the Guarantors under the Guarantee
(the "Lease Secured Obligations"). Lessee shall, at its expense, do any further
act and execute, acknowledge, deliver, file, register and record any further
documents which Lessor may reasonably request in order to protect its title to
and perfected security interest in the Equipment, subject to no Liens other than
Permitted Liens, and Lessor's rights and benefits under this Lease. Subject to
the provisions of Section 10.3(b) of the Lease, Lessee shall promptly and duly
execute and deliver to Lessor such documents and assurances and take such
further action as Lessor may from time to time reasonably request in order to
carry out more effectively the intent and purpose of this Lease and the other
Operative Agreements, to establish and protect the rights and remedies created
or intended to be created in favor of Lessor hereunder and thereunder, and to
establish, perfect and maintain the right, title and interest of Lessor, in and
to the Equipment, subject to no Lien other than Permitted Liens and Lessor
Liens, or of such financing statements or fixture filings or other documents
with respect hereto as Lessor may from time to time reasonably request, and
Lessee agrees to execute and deliver promptly such of the foregoing financing
statements and fixture filings or other documents as may require execution by
Lessee. To the extent permitted by applicable laws, Lessee hereby 


<PAGE>   30

                                                                              25


authorizes any such financing statements and fixture filings to be filed without
the necessity of the signature of Lessee, if Lessee has failed to sign any such
instrument within 10 Business Days after written request therefor by Lessor.

                  28.2 UCC Remedies. If a Lease Event of Default shall occur and
be continuing, Lessor may exercise, in addition to all other rights and remedies
granted to it in this Lease and in any other Operative Agreement, all rights and
remedies of a secured party under the UCC. Without limiting the generality of
the foregoing, Lessor, without demand of performance or other demand,
presentment, protest, advertisement or notice of any kind (except any notice
required by law referred to below) to or upon Lessee or any other Person (all
and each of which demands, defenses, advertisements and notices are hereby
waived), may in such circumstances forthwith collect, receive, appropriate and
realize upon the Equipment, or any part thereof, and/or may forthwith sell,
lease, assign, give option or options to purchase, or otherwise dispose of and
deliver the Equipment or any part thereof (or contract to do any of the
foregoing), in one or more parcels at public or private sale or sales, at any
exchange, broker's board or office of Lessor or elsewhere upon such terms and
conditions as it may deem advisable and at such prices as it may deem best, for
cash or on credit or for future delivery without assumption of any credit risk.
Lessor shall have the right upon any such public sale or sales, and, to the
extent permitted by law, upon any such private sale or sales, to purchase the
whole or any part of the Equipment so sold, free of any right or equity of
redemption in which right or equity is hereby waived or released. Lessee further
agrees, at Lessor's request, to assemble the Equipment and make it available to
the Lessor at places which the Lessor shall reasonably select, whether at
Lessee's premises or elsewhere. Lessor shall apply the net proceeds of any
action taken by it pursuant to this subsection, after deducting all reasonable
costs and expenses of every kind incurred in connection therewith or incidental
to the care or safekeeping of any of the Equipment or in any way relating to the
Equipment or the rights of Lessor, including, without limitation, reasonable
attorneys' fees and disbursements, to the payment in whole or in part of the
Lease Secured Obligations, in such order as Lessor may elect, and only after
such application and after the payment by Lessor of any other amount required by
any provision of law, including, without limitation, Section 9-504(1)(c) of the
UCC, need Lessor account for the surplus, if any, to Lessee. If any notice of a
proposed sale or other disposition of the Equipment shall be required by law,
such notice shall be deemed reasonable and proper if given at lease 10 Business
Days before such sale or other disposition.

                  28.3 Waiver; Deficiency. Lessee waives and agrees not to
assert any rights or privileges which it may acquire under Section 9-112 of the
UCC. Lessee shall remain liable for any deficiency if the proceeds of any sale
or other disposition of the Equipment are insufficient to pay the Lease Secured
Obligations and the reasonable fees and disbursements of any attorneys employed
by Lessor to collect such deficiency.

                  28.4 Agent's Appointment as Attorney-in-Fact; Agent's
Performance of Lessee's Obligations. Lessee hereby irrevocable constitutes and
appoints the Agent and any officer or agent thereof, as assignee of all of
Lessor right under this Lease pursuant to the Assignment of Lease, with full
power of substitution, as its true and lawful attorney-in-fact with full
irrevocable power and authority in the place and stead of Lessee and in the name


<PAGE>   31

                                                                              26

of Lessee or in its own name, from time to time in the Agent's discretion, for
the purpose of carrying out the terms of this Lease, to take any and all
appropriate action and to execute any and all documents and instruments which
may be necessary or desirable to accomplish the purposes of this Lease, and,
without limiting the generality of the foregoing, Lessee hereby gives the Agent
the power and right, on behalf of Lessee, without notice to or assent by Lessee,
to do any or all of the following:

                  (a) in the name of Lessee or its own name, or otherwise, take
         possession of and indorse and collect any checks, drafts, notes,
         acceptances or other instruments for the payment of moneys due under or
         with respect to the Equipment and file any claim or take any other
         action or proceeding in any court of law or equity or otherwise deemed
         appropriate by the Agent for the purpose of collecting any and all such
         moneys due under or with respect to the Equipment whenever payable;

                  (b) pay or discharge taxes and Liens levied or placed on or
         threatened against the Equipment, effect any repairs or any insurance
         called for by the terms of this Lease and to pay all or any part of the
         premiums therefor and the costs thereof;


                  (c) execute, in connection with the sale provided for in
         Section 28.2 hereof, any indorsements, assignments or other instruments
         of conveyance or transfer with respect to the Equipment; and

                  (d) (1) direct any party liable for any payment under any of
         the Equipment to make payment of any and all moneys due or to become
         due thereunder directly to the Agent or as the Agent shall direct; (2)
         ask or demand for, collect, receive payment of and receipt for, any and
         all moneys, claims and other amounts due or to become due at any time
         in respect of or arising out of any Equipment; (3) sign and indorse any
         invoices, freight or express bills, bills of lading, storage or
         warehouse receipts, drafts against debtors, assignments, verifications,
         notices and other documents in connection with any of the Equipment;
         (4) commence and prosecute any suits, actions or proceedings at law or
         in equity in any court of competent jurisdiction to enforce any other
         right in respect of any Equipment; (5) defend any suit, action or
         proceeding brought against Lessee with respect to any Equipment; (6)
         settle, compromise or adjust any such suit, action or proceeding and,
         in connection therewith, to give such discharges or releases as the
         Agent may deem appropriate; and (7) generally, sell, transfer, pledge
         and make any agreement with respect to or otherwise deal with any of
         the Equipment as fully and completely as thought the Agent were the
         absolute owner thereof for all purposes, and do, at the Agent's option
         and the Lessee's expense, at any time, or from time to time, all acts
         and things which the Agent reasonably deems necessary to protect,
         preserve or realize upon the Equipment and the Agent's security
         interests therein and to effect the intent of this Lease, all as fully
         and effectively as the Lease might do.

         Anything in this subsection to the contrary notwithstanding, the Agent
agrees that it will not exercise any rights under the power of attorney provided
for in this subsection unless a Lease Event of Default shall have occurred and
be continuing.

                                                                               3



and/or enforcing any rights with respect to, or collecting against, the
Guarantors under this Guarantee.

                  3. Right of Set-off. In addition to any rights now or
hereafter granted under applicable law or otherwise, and not by way of
limitation of any such rights, upon the occurrence and during the continuance of
an Event of Default, the Investor, Agent and each Lender is hereby authorized at
any time or from time to time, without presentment, demand, protest or other
notice of any kind to the Borrower, the Guarantors or to any other Person, any
such notice being hereby expressly waived, to set off and to appropriate and
apply any and all deposits (general or special) and any other Indebtedness at
any time held or owing by the Investor, Agent or such Lender (including, without
limitation, by branches and agencies of the Investor, Agent or such Lender
wherever located) to or for the credit or the account of the Guarantors against
and on account of the obligations and liabilities of the Guarantors hereunder or
under any of the other Operative Agreements, and all other claims of any nature
or description arising out of or connected with this Guarantee or any other
Operative Agreement, irrespective of whether the Investor, Agent or such Lender
shall have made any demand hereunder and although said obligations, liabilities
or claims, or any of them, shall be contingent or unmatured. The Investor, Agent
and each Lender shall notify such Guarantor promptly of any such set-off and the
application made by the Investor, Agent or such Lender; provided, that the
failure to give such notice shall not affect the validity of such set-off and
application.

                  4. No Subrogation. Notwithstanding any payment or payments
made by the Guarantors hereunder or any set-off or application of funds of the
Guarantors by any Lender, the Guarantors shall not be entitled to exercise or
enforce any subrogation rights of the Investor, Agent or any Lender against the
Borrower or any other Person or any collateral security or guarantee or right of
offset held by the Investor, Agent or any Lender for the payment of the
Guaranteed Obligations, nor shall the Guarantors seek or be entitled to seek any
contribution or reimbursement from the Borrower or any other Person in respect
of payments made by the Guarantors hereunder, until all amounts owing to the
Investor, Agent and the Lenders by the Borrower on account of the Guaranteed
Obligations and all amounts owing hereunder are paid in full and the Commitments
are terminated. If any amount shall be paid to the Guarantors on account of such
subrogation rights at any time when all of the Guaranteed Obligations and all
amounts owing hereunder shall not have been paid in full or the Commitments
shall not have been terminated, such amount shall be held by the Guarantors in
trust for the Investor, Agent and the Lenders, segregated from other funds of
the Guarantors, and shall, forthwith upon receipt by the Guarantors, be turned
over to the Agent in the exact form received by the Guarantors (duly indorsed by
the Guarantors to the Agent, if required), to be applied against the Guaranteed
Obligations, whether matured or unmatured, in such order as the Agent may
determine.

                  5. Amendments, etc. with respect to the Guaranteed
Obligations; Waiver of Rights. The Guarantors shall remain obligated hereunder
notwithstanding that, without any reservation of rights against the Guarantors
and without notice to or further assent by the Guarantors, any demand for
payment of any of the Guaranteed Obligations made by the Investor, Agent or any
Lender may be rescinded by such party and any of the Guaranteed Obligations
continued, and the Guaranteed Obligations, or the liability of any other party

                                                                               4


upon or for any part thereof, or any collateral security or guarantee therefor
or right of offset with respect thereto, may, from time to time, in whole or in
part, be renewed, extended, amended, modified, accelerated, compromised, waived,
surrendered or released by the Investor, Agent or any Lender, and the Credit
Agreement, the Participation Agreement and the other Operative Agreements may be
amended, modified, supplemented or terminated, in whole or in part, as the Agent
(or the Required Lenders, as the case may be) may deem advisable from time to
time in accordance with the terms thereof, and any collateral security,
guarantee or right of offset at any time held by the Investor, Agent or any
Lender for the payment of the Guaranteed Obligations may be sold, exchanged,
waived, surrendered or released. Neither the Investor, Agent nor any Lender
shall have any obligation to protect, secure, perfect or insure any Lien at any
time held by it as security for the Guaranteed Obligations or for this Guarantee
or any property subject thereto. When making any demand hereunder against the
Guarantors, the Investor, Agent or any Lender may, but shall be under no
obligation to, make a similar demand on the Borrower or any other guarantor, and
any failure by the Investor, Agent or any Lender to make any such demand or to
collect any payments from the Borrower or any other guarantor or any release of
the Borrower or such other guarantor shall not relieve the Guarantors from their
obligations under this Guarantee, and shall not impair or affect the rights and
remedies, express or implied, or as a matter of law, of the Investor, Agent or
any Lender against the Guarantors. For the purposes hereof "demand" shall
include the commencement and continuance of any legal proceedings.

                  6. Guarantee Absolute and Unconditional. Each Guarantor waives
any and all notice of the creation, renewal, extension or accrual of any of the
Guaranteed Obligations and notice of or proof of reliance by the Investor, Agent
or any Lender upon this Guarantee or acceptance of this Guarantee, the
Guaranteed Obligations, and any of them, shall conclusively be deemed to have
been created, contracted or incurred, or renewed, extended, amended or waived,
in reliance upon this Guarantee; and all dealings between the Borrower and such
Guarantor, on the one hand, and the Agent and the Lenders, on the other hand,
likewise shall be conclusively presumed to have been had or consummated in
reliance upon this Guarantee. Each Guarantor waives diligence, presentment,
protest, demand for payment and notice of default or nonpayment to or upon the
Borrower or such Guarantor with respect to the Guaranteed Obligations. Each
Guarantor understands and agrees that this Guarantee shall be construed as a
continuing, absolute and unconditional guarantee and surety of payment without
regard to (a) the validity, regularity or enforceability of the Credit Agreement
or any other Operative Agreement, any of the Guaranteed Obligations or any other
collateral security therefor or guarantee or right of offset with respect
thereto at any time or from time to time held by the Investor, Agent or any
Lender, (b) any defense, set-off or counterclaim (other than a defense of
payment or performance) which may at any time be available to or be asserted by
the Borrower or such Guarantor against the Investor, Agent or any Lender, or (c)
any other circumstance whatsoever (with or without notice to or knowledge of the
Borrower or such Guarantor) which constitutes, or might be construed to
constitute, an equitable or legal discharge of the Borrower for the Guaranteed
Obligations, or of such Guarantor under this Guarantee, in bankruptcy or in any
other instance. When pursuing its rights and remedies hereunder against any
Guarantor, the Agent and any Lender may, but shall be under no obligation to,
pursue such rights and remedies as it may have against the Borrower or any



<PAGE>   5
                                                                               5



other Person or against any collateral security or guarantee for the Guaranteed
Obligations or any right of offset with respect thereto, and any failure by the
Investor, Agent or any Lender to pursue such other rights or remedies or to
collect any payments from the Borrower or any such other Person or to realize
upon any such collateral security or guarantee or to exercise any such right of
offset, or any release of the Borrower or any such other Person or any such
collateral security, guarantee or right of offset, shall not relieve such
Guarantor of any liability hereunder, and shall not impair or affect the rights
and remedies, whether express, implied or available as a matter of law, of the
Agent and the Lenders against such Guarantor. This Guarantee shall remain in
full force and effect and be binding in accordance with and to the extent of its
terms upon such Guarantor and the successors and assigns thereof, and shall
inure to the benefit of the Agent and the Lenders, and their respective
successors, indorsees, transferees and assigns, until all the Guaranteed
Obligations and the obligations of such Guarantor under this Guarantee shall
have been satisfied by payment in full and the Commitments shall be terminated,
notwithstanding that from time to time during the term of the Credit Agreement
the Borrower may be free from any Guaranteed Obligations.

                  7. Reinstatement. This Guarantee shall continue to be
effective, or be reinstated, as the case may be, if at any time payment, or any
part thereof, of any of the Guaranteed Obligations is rescinded or must
otherwise be restored or returned by the Investor, Agent or any Lender upon the
insolvency, bankruptcy, dissolution, liquidation or reorganization of the
Borrower or the Guarantors, or upon or as a result of the appointment of a
receiver, intervenor or conservator of, or trustee or similar officer for, the
Borrower or the Guarantors or any substantial part of its property, or
otherwise, all as though such payments had not been made.

                  8. Payments. The Guarantors hereby guarantee that payments
hereunder will be paid to the Agent without set-off or counterclaim in Dollars
at the office of the Agent located at 270 Park Avenue, New York, New York 10017.

                  9. Representations, Warranties. In order to induce the Lenders
to enter into the Credit Agreement and to make the Loans, the Investor to enter
into the Participation Agreement and make the Investor Contribution and the
Lessor to enter into the Lease, HCC hereby represents and warrants to the
Beneficiaries as follows, all of which shall survive the execution and delivery
of this Guarantee and the Credit Agreement and the making of the Loans:

                  9.1 Financial Condition. (a) The consolidated balance sheets
of HCC and its consolidated Subsidiaries as at December 31, 1997 and December

material respects, the consolidated financial condition of HCC and its
consolidated Subsidiaries as at such dates, and the consolidated results of

                                                                               6



of which have heretofore been furnished to each Lender, present fairly, in all
material respects, the consolidated financial condition of HCC, and its
consolidated Subsidiaries as at such dates, and the consolidated results of its
operations and consolidated cash flows for the three month period then ended
(subject to normal year-end audit adjustments).

                  (b) All such financial statements, including the related
schedules and notes thereto, have been prepared in accordance with GAAP applied
consistently throughout the periods involved (except as approved by such
accountants or Responsible Officer, as the case may be, and as disclosed
therein). Other than the Guarantor Obligations permitted under Section 11.4
below, neither HCC nor any of its consolidated Subsidiaries had, at the date of
the most recent balance sheet referred to above, any material Guarantor
Obligation, reasonably foreseeable contingent liability or liability for taxes,
or any long-term lease or unusual forward or long-term commitment, including,
without limitation, any interest rate or foreign currency swap or exchange
transaction, which is not reflected in the foregoing statements or in the notes
thereto. Except as disclosed on Schedule 9.1(b) hereto, during the period from
March 31, 1998 to and including the date hereof there has been no sale, transfer
or other disposition by HCC or any of its consolidated Subsidiaries of any
material part of its business or property and no purchase or other acquisition
of any business or property (including any capital stock of any other Person)
material in relation to the consolidated financial condition of HCC and its
consolidated Subsidiaries at March 31, 1998.

                  9.2 No Change. Except as set forth in HCC's form 10-Q filed
with respect to the period ending March 31, 1998, (a) there has been no
development or event nor any prospective development or event, which has had or
would reasonably be expected to have a Material Adverse Effect and (b) except as
disclosed on Schedule 9.2 to this Guarantee, as of the date hereof, no dividends
or other distributions have been declared, paid or made upon the Capital Stock
of HCC nor has any of the Capital Stock of HCC been redeemed, retired, purchased
or otherwise acquired for value by HCC or any of its respective Subsidiaries.

                  9.3 Corporate Existence; Compliance with Law. Each Guarantor
(a) is duly organized, validly existing and in good standing under the laws of
the jurisdiction of its organization, (b) has the corporate power and authority,
and the legal right, to own and operate its property, to lease the property it
operates as lessee and to conduct the business in which it is currently engaged,
(c) is duly qualified as a foreign corporation and in good standing under the
laws of each jurisdiction where its ownership, lease or operation of property or
the conduct of its business requires such qualification, except where the
failure to be so qualified would not reasonably be expected to have a Material
Adverse Effect, and (d) is in compliance with all Requirements of Law except to
the extent that the failure to comply therewith would not, in the aggregate,
reasonably be expected to have a Material Adverse Effect.

                  9.4 Corporate Power; Authorization; Enforceable Obligations.
Each Guarantor has the corporate power and authority, and the legal right, to
make, deliver and perform the Operative Agreements to which it is a party. HCC
has the corporate power and authority, and the legal right, to perform the
Operative Agreements and has taken all 



<PAGE>   7

                                                                               7


necessary corporate action to authorize the performing under the Operative
Agreements on the terms and conditions of the Operative Agreements. Each
Guarantor has taken all necessary corporate action to authorize the execution,
delivery and performance of this Guarantee. No consent or authorization of,
filing with or other act by or in respect of, any Governmental Authority or any
other Person (other than consents that have been obtained and consents or
authorizations the failure to obtain would not, in the aggregate, reasonably be
expected to have a Material Adverse Effect) is required in connection with the
Loans or with the execution, delivery, performance, validity or enforceability
of this Guarantee or any of the other Operative Agreements. This Guarantee has
been duly executed and delivered on behalf of the Guarantors party hereto. This
Guarantee constitutes, each Operative Agreement when executed and delivered will
constitute, a legal, valid and binding obligation of the Guarantors party
thereto enforceable against such Guarantors in accordance with their respective
terms, except as enforceability may be limited by applicable bankruptcy,
insolvency, reorganization, moratorium or similar laws affecting the enforcement
of creditors' rights generally and by general equitable principles (whether
enforcement is sought by proceedings in equity or at law).

                  9.5 No Legal Bar. The execution, delivery and performance of
this Guarantee and the other Operative Agreements, the Loans and the use of the
proceeds thereof will not violate any Requirement of Law or Contractual
Obligation of any Guarantor party thereto and will not result in, or require,
the creation or imposition of any Lien on any of their respective properties or
revenues pursuant to any such Requirement of Law or Contractual Obligation,
except as contemplated hereby or thereby and except to the extent any such
violation or creation or imposition of a Lien would not reasonably be expected
to have a Material Adverse Effect.

                  9.6 No Material Litigation. Except as set forth in HCC's Form
10-Q, filed with respect to the period ending March 31, 1998, no litigation,
investigation or proceeding of or before any arbitrator or Governmental
Authority is pending or, to the knowledge of HCC, threatened by or against any
Guarantor or against any of their respective properties or revenues (a) with
respect to this Guarantee or the other Operative Agreements or any of the
transactions contemplated hereby, or (b) which would reasonably be expected to
have a Material Adverse Effect.

                  9.7 No Default. None of the Guarantors nor any of their
respective Subsidiaries is in default under or with respect to any of their
respective Contractual Obligations in any respect which if not cured would
reasonably be expected to have a Material Adverse Effect. No Default or Event of
Default has occurred and is continuing.

                  9.8 Ownership of Property; Liens; Leases of Equipment. Each of
the Guarantors has good record and marketable title in fee simple (except for
exceptions to title as will not in the aggregate materially interfere with the
present or contemplated use of the property affected thereby) to, or a valid
leasehold interest in, all its real property, and good title to all its other
property, and none of such property is subject to any Lien except as permitted
by Section 11.3. None of the Equipment or Inventory (as defined in the Uniform
Commercial Code) owned by any Guarantor has been leased by such Guarantor as
lessor, except pursuant to operating leases (which do not constitute Financing
Leases). As used

                                                                               8

herein, Equipment or Inventory leased by a Guarantor under a Financing Lease
shall be deemed "owned" by such Guarantor.

                  9.9 Intellectual Property. Each Guarantor owns, or is licensed
to use, all trademarks, tradenames, trade secrets, copyrights, technology,
know-how and processes necessary for the conduct of its business as currently
conducted except for those the failure to own or license which would not
reasonably be expected to have a Material Adverse Effect (the "Intellectual
Property"). To the knowledge of each Guarantor, no claim has been asserted and
is pending by any Person challenging or questioning the use of any such
Intellectual Property or the validity or effectiveness of any such Intellectual
Property, nor does each Guarantor know of any valid basis for any such claim,
which would reasonably be expected to have a Material Adverse Effect. The use of
such Intellectual Property by the Guarantors does not infringe on the rights of
any Person, except for such claims and infringements that, in the aggregate,
would not reasonably be expected to have a Material Adverse Effect.

                  9.10 Taxes. Each of the Guarantors has filed or caused to be
filed all tax returns which, to the knowledge of each Guarantor, are required to
be filed and has paid all taxes shown to be due and payable on said returns or
on any assessments made against it or any of its property and all other taxes,
fees or other charges imposed on it or any of its property by any Governmental
Authority (other than any the amount or validity of which are currently being
contested in good faith by appropriate proceedings and with respect to which
reserves in conformity with GAAP have been provided on the books of any of the
Guarantors, as the case may be); no tax Lien has been filed against the property
of any Guarantor, and, to the knowledge of each Guarantor, no claim is being
asserted, with respect to any such tax, fee or other charge.

                  9.11 Federal Regulations. No part of the proceeds of any Loans
will be used for "purchasing" or "carrying" any "margin stock" within the
respective meanings of each of the quoted terms under Regulation U of the Board
of Governors of the Federal Reserve System as now and from time to time
hereafter in effect or for any purpose which violates the provisions of the
Regulations of such Board of Governors. If requested by any Lender or the Agent,
HCC will furnish to the Agent and each Lender a statement to the foregoing
effect in conformity with the requirements of FR Form U-1 referred to in said
Regulation U.

                  9.12 ERISA. Neither a Reportable Event nor an "accumulated
funding deficiency" (within the meaning of Section 412 of the Code or Section
302 of ERISA) has occurred during the five-year period prior to the date on
which this representation is made or deemed made with respect to any Plan, and
each Plan has complied in all material respects with the applicable provisions
of ERISA and the Code. No termination of a Single Employer Plan has occurred and
no lien in favor of the PBGC or a Plan has arisen during the five-year period
prior to the date as of which this representation is deemed made. The present
value of all accrued benefits under each Single Employer Plan maintained by HCC,
or any Commonly Controlled Entity (based on those assumptions used to fund the
Plans) did not, as of the last annual valuation date prior to the date on which
this representation is made or deemed made, exceed the value of the assets of
such Plan allocable to such 


<PAGE>   9
                                                                               9



accrued benefits. Neither HCC nor any Commonly Controlled Entity has had a
complete or partial withdrawal from any Multiemployer Plan, and neither HCC nor
any Commonly Controlled Entity would become subject to any liability under ERISA
if HCC or any such Commonly Controlled Entity were to withdraw completely from
all Multiemployer Plans as of the valuation date most closely preceding the date
on which this representation is made or deemed made. No such Multiemployer Plan
is in Reorganization or Insolvent. The present value (determined using actuarial
and other assumptions which are reasonable in respect of the benefits provided
and the employees participating) of the liability of HCC and each Commonly
Controlled Entity for post retirement benefits to be provided to their current
and former employees under Plans which are welfare benefit plans (as defined in
Section 3(1) of ERISA) does not, in the aggregate, exceed the assets under all
such Plans allocable to such benefits.

                  9.13 Investment Company Act; Other Regulations. None of the
Guarantors is an "investment company", or a company "controlled" by an
"investment company", within the meaning of the Investment Company Act of 1940,
as amended. None of the Guarantors is subject to regulation under any Federal or
State statute or regulation which limits its ability to incur Indebtedness or
change rates or change tariffs. None of the Guarantors are "holding companies"
or "subsidiary companies" of a "holding company" or a "subsidiary company" of a
"holding company" within the meaning of the Public Utility Holding Company Act
of 1935, as amended.

                  9.14 Subsidiaries. As of the Initial Closing Date, HCC has no
Subsidiaries other than as set forth on Schedule 9.14. Except if a Guarantor,
other than cash or Cash Equivalents located in bank accounts at the Agent, none
of the assets owned by any Unqualified Subsidiary as of the date hereof are
located within the United States of America or any territory thereof.

                  9.15 Environmental Matters. Each of the representations and
warranties set forth in paragraphs (a) through (e) of this subsection is true
and correct with respect to each parcel of real property owned or operated by
any of the Guarantors (the "Properties"), except to the extent that the facts
and circumstances giving rise to any such failure to be so true and correct
would not reasonably be expected to have a Material Adverse Effect:

                  (a) Except as set forth on Schedule 9.15, the Properties do
         not contain, and have not previously contained, in, on, or under,
         including, without limitation, the soil and groundwater thereunder, any
         Hazardous Substances in concentrations which violate Environmental
         Laws.

                  (b) Except as set forth on Schedule 9.15, the Properties and
         all operations and facilities at the Properties are in compliance with
         all Environmental Laws, and there is no Hazardous Substances
         contamination or violation of any Environmental Law which would
         reasonably be expected to interfere with the continued operation of any
         of the Properties or impair the fair saleable value of any thereof.

                  (c) Except as set forth on Schedule 9.15, none of the
         Guarantors has received any complaint, notice of violation, alleged
         violation, investigation or 



<PAGE>   10
                                                                              10


         advisory action or of potential liability or of potential
         responsibility regarding environmental protection matters or
         environmental permit compliance with regard to the Properties, nor is
         HCC aware that any Governmental Authority is contemplating delivering
         to any Guarantor any such notice.

                  (d) Hazardous Substances have not been generated, treated,
         stored, disposed of, at, on or under any of the Properties, nor have
         any Hazardous Substances been transferred to any other location, in
         violation of any Environmental Laws from the Properties or as a result
         of the sale or lease of any equipment or inventory of any Guarantor.

                  (e) There are no governmental, administrative actions or
         judicial proceedings pending or contemplated under any Environmental
         Laws to which any Guarantor is or to HCC's knowledge will be named as a
         party with respect to the Properties, nor to HCC's knowledge are there
         any consent decrees or other decrees, consent orders, administrative
         orders or other orders, or other administrative or judicial
         requirements outstanding under any Environmental Law with respect to
         any of the Properties.

                  9.16 Accuracy and Completeness of Information. The factual
statements contained in the Operative Agreements and each other agreement,
instrument, certificate and document related thereto and any other certificates
or documents furnished or to be furnished to the Agent or the Lenders by any
Guarantor from time to time in connection with this Guarantee (in any case
excluding any of the financial statements referred to in Section 9.1(a) and 10.1
hereof), taken as a whole, and taking into consideration all corrections or
substituted documents, do not and will not, as of the date when made, contain
any untrue statement of a material fact or omit to state a material fact
necessary in order to make the statements contained therein not misleading in
light of the circumstances in which the same were made, all except as otherwise
qualified herein or therein.

                  10. Affirmative Covenants of the Guarantor. Each Guarantor
hereby covenants and agrees that so long as this Guarantee is in effect and
until the Commitments have terminated and the Guaranteed Obligations and all
amounts owing hereunder are paid in full such Guarantor will:

and preserve, renew and keep in full force and effect its corporate existence
and take all reasonable action to maintain all rights, privileges and franchises
necessary or desirable in the normal conduct of its business except as otherwise
permitted pursuant to Section 11.5; comply with all Contractual Obligations and
Requirements of Law except to the extent that failure to comply therewith would
not, in the aggregate, reasonably be expected to have a Material Adverse Effect.

                  10.5 Maintenance of Property; Insurance. HCC will, and will
cause each of its Subsidiaries to, (a) keep and maintain all property material

<PAGE>   13
                                                                              13


amounts and against such risks as are customarily maintained by companies
engaged in the same or similar businesses operating in the same or similar
locations.

                  10.6 Inspection of Property; Books and Records; Discussions.
Keep proper books of records and account in which full, true and correct entries
in conformity with GAAP and all Requirements of Law shall be made of all
dealings and transactions in relation to its business and activities; and permit
representatives of Investor or any Lender to visit and inspect any of its
properties and examine and make abstracts from any of its books and records at
any reasonable time and as often as may reasonably be desired and to discuss the
business, operations, properties and financial and other condition of HCC and
Subsidiaries of HCC with officers and employees of HCC and Subsidiaries of HCC
and with its independent certified public accountants; provided, however, that
no such visit, inspection or examination or discussion shall unreasonably
disrupt or interfere with normal operations of HCC or any of its Subsidiaries
and any such representatives of the Investor, Agent and the Lenders shall be
accompanied by a Responsible Officer of HCC. No failure to comply with any
request for the exercise of rights hereunder shall be cause for any Event of
Default unless such request is submitted in writing to HCC with reference to
this Section 10.6.

                  10.7 Notices. Promptly give notice to the Investor, Agent and
each Lender of:

                  (a) the occurrence of any Default or Event of Default of which
         HCC has actual knowledge;

                  (b) any (i) default or event of default by HCC or any of its
         Subsidiaries under or with respect to any of their respective
         Contractual Obligations in any respect which, if not cured, would
         reasonably be expected to have a Material Adverse Effect, or to HCC's
         knowledge any default or event of default by any third party under or
         with respect to any Contractual Obligation of said third party with HCC
         or any of its Subsidiaries in a respect which, if not cured, would
         reasonably be expected to have a Material Adverse Effect or (ii)
         litigation, investigation or proceeding of which HCC has actual
         knowledge which may exist at any time between HCC or any Subsidiary of
         HCC and any Governmental Authority, which in either case, if not cured
         or if adversely determined, as the case may be, would reasonably be
         expected to have a Material Adverse Effect;

                  (c) any litigation or proceeding affecting HCC or any
         Subsidiary of HCC of which HCC has actual knowledge in which the amount

         be expected to have a Material Adverse Effect.

Each notice pursuant to this subsection shall be accompanied by a statement of a
Responsible Officer setting forth details of the occurrence referred to therein
and stating what action HCC proposes to take with respect thereto.

                  10.8     Environmental Laws.

                  (a) Comply in all material respects with, and undertake all
         reasonable efforts to ensure compliance by all tenants and subtenants,
         if any, with, all Environmental Laws and obtain and comply in all
         material respects with and maintain, and undertake all reasonable
         efforts to ensure that all tenants and subtenants obtain and comply
         with and maintain, any and all licenses, approvals, registrations or
         permits required by Environmental Laws, and upon discovery of any
         non-compliance or suspected non-compliance, undertake all reasonable
         efforts to attain full compliance;

                  (b) Conduct and complete all investigations, studies, sampling
         and testing, and all remedial, removal and other actions required under
         Environmental Laws and promptly comply in all material respects with

         respecting Environmental Laws, except to the extent that the failure to
         so conduct, complete or take such actions, or to comply with such
         orders and directives, would not in the aggregate reasonably be
         expected to have a Material Adverse Effect; and

                  (c) Defend, indemnify and hold harmless the Agent and the
         Lenders, and their respective employees, agents, officers and
         directors, from and against any claims, demands, penalties, fines,
         liabilities, settlements, damages, costs and expenses of whatever kind
         or nature known or unknown, contingent or otherwise, arising out of, or
         in any way relating to the violation of or noncompliance with any
         Environmental Laws applicable to the real property owned or operated by
         HCC or any Subsidiary of HCC, or any orders, requirements or demands of
         Governmental Authorities related thereto, including, without
         limitation, reasonable attorney's and consultant's fees, investigation
         and laboratory fees, court costs and litigation expenses, except to the
         extent that any of the foregoing arise out of the gross negligence or
         willful misconduct of the party seeking indemnification therefor.

                  (d) Maintain a program to identify and promote substantial
         compliance with and to minimize prudently any liabilities or potential
         liabilities under any Environmental Law that may affect HCC or any of

                  10.9 Subsequent Guarantees. HCC shall cause each Qualified
Subsidiary of HCC for which the aggregate value of all assets owned by such
Qualified Subsidiary is or becomes greater than $20,000,000, to execute an
amendment to this Guarantee, substantially in the form of Exhibit A hereto
within one-year after the later of (i) the date on which such Qualified
Subsidiary becomes a Subsidiary of HCC and (ii) the date on which such Qualified
Subsidiary's assets attain an aggregate value in excess of $20,000,000;
provided, however, that if during such one-year period the aggregate value of
such Qualified Subsidiary's assets is or becomes $20,000,000 or less, such
Qualified Subsidiary shall not be required to become a party to this Guarantee.

                  10.10 Year 2000 Matters. Any reprogramming required to permit
the proper functioning (but only to the extent that such proper functioning
would otherwise be impaired by the occurrence of the year 2000) in and following
the year 2000 of computer systems and other equipment containing embedded
microchips, in either case owned or operated by Guarantors or used or relied
upon in the conduct of their business (including any such systems and other
equipment supplied by others or with which the computer systems of Guarantors
interface), and the testing of all such systems and other equipment as so
reprogrammed, will be completed by January 1, 1999. The costs to Guarantors that
have not been incurred as of the date hereof for such reprogramming and testing
and for the other reasonably foreseeable consequences to them of any improper
functioning of other computer systems and equipment containing embedded
microchips due to the occurrence of the year 2000 could not reasonably be
expected to result in an Event of Default or to have a Material Adverse Effect.
Except for any reprogramming referred to above, the computer systems of
Guarantors are and, with ordinary course upgrading and maintenance, will
continue to be, sufficient for the conduct of Guarantors' business as currently
conducted.

                  11. Negative Covenants. Each Guarantor hereby agrees that so
long as this Guarantee is in effect and until the Commitments have terminated
and the Guaranteed Obligations and all amounts owing hereunder are paid in full,
the Guarantor shall not, directly or indirectly:

                  11.1 Financial Condition Covenants. (a) Maintenance of
Consolidated Indebtedness to Consolidated Capitalization. Permit the ratio
(expressed as a percentage) of Consolidated Indebtedness to Consolidated
Capitalization of HCC and its Subsidiaries as at the end of any of HCC's fiscal
quarters to be greater than .65 to 1.0.

                  (b) Current Ratio. Permit the Current Ratio of HCC and its
Subsidiaries at the end of any of HCC's fiscal quarters to be less than 1.0 to
1.0.

                  (c) Consolidated U.S. EBITDA to Consolidated Indebtedness.
Permit the ratio of Consolidated U.S. EBITDA to Consolidated Indebtedness for
the four consecutive fiscal quarters of HCC most recently ended to be less than
1.0 to 4.5.

                  (d) Interest Coverage Ratio. Permit the ratio of Consolidated
EBITDA to Consolidated Interest Expense for the period of four consecutive
fiscal quarters of HCC most recently ended to be less than 2.5 to 1.0.

         immediately after giving effect to the acquisition of such Person by
         HCC or any of its Subsidiaries no Default or Event of Default shall
         have occurred and be continuing;

                  (j) Indebtedness not contemplated by clauses (a)-(i) above not

terms thereof, and agrees to pay and deliver to the Assignee (or its designee)

                  (c) Subject to the Excepted Rights, the Lessee shall cause the
Lease Rents and other sums payable to the Assignor under the Lease to be
delivered to the Assignee (or its designee), as agent under the Credit

designee) shall have "collected funds" on the date and at the time payments are
due under the Lease.

                  (d) The Guarantors shall cause the Guaranteed Obligations,

Lease and this Consent in accordance with their respective terms, and to take no
action to terminate (except in accordance with the express terms of the Lease),
annul, rescind or avoid the Lease or this Consent or to abate, reduce, offset,
suspend or defer or make any counterclaim or raise any defense (other than the
defense of payment to the Assignee (or its designee)) with respect to the Lease
Rents payable thereunder or to cease paying such Lease Rents to the Assignee (or
its designee) as provided herein.

                  (f) The Guarantors hereby agree to remain obligated under the

any counterclaim or raise any defense (other than the defense of payment to the
Assignee (or its designee)) with respect to the Guaranteed Obligations payable
thereunder.

                  (g) The Lessee and the Guarantors hereby agree that upon the
occurrence of a Default or an Event of Default, the Assignee (or its designee)
shall have the right to deliver a notice of such default and make demand for
payment under the Guarantee, which shall be effective for all purposes as if
sent by the Assignor.

                  (h) The Lessee shall notify the Assignee (or its designee) at
its address specified in the Participation Agreement, or such other address as
the Assignee may designate, of any Lease Event of Default and agrees that no
such default shall entitle the Lessee to terminate, annul, rescind or avoid the
Lease or reduce or abate the Lease Rents or other sums payable thereunder.

                  4. Amendment or Termination; Assignee's Designation. (a) The
Lessee agrees that it will not, unilaterally or by agreement, subordinate,
amend, supplement, modify, extend (except in accordance with the express terms
of the Lease), discharge, waive or terminate (except in accordance with the
express terms of the Lease) the Lease or this Consent or any provision of any
thereof without the Assignee's prior written consent, which consent may be
withheld in the Assignee's sole discretion, and that any attempted
subordination, amendment, supplement, modification, extension, discharge, waiver
or termination without such consent shall be null and void. In the event that
the Lease shall be amended or supplemented as herein permitted, the Lease, as so
amended or supplemented, shall continue to be subject to the provisions of the
Assignment and this Consent without the necessity of any further act by any of
the parties hereto. Nothing in this Section 4 shall be construed as limiting or
otherwise affecting in any way the Assignor's Excepted Rights or Shared Rights.

                  (b) The Guarantors agree that they will not, unilaterally or
by agreement, subordinate, amend, supplement, modify, extend (except in
accordance with the express terms of the Guarantee), discharge, waive or
terminate (except in accordance with the express terms of the Guarantee) the
Guarantee or this Consent or any provision of any thereof without the Assignee's
prior written consent, which consent may be withheld in the Assignee's sole
discretion, and that any attempted subordination, amendment, supplement,
modification, extension, discharge, waiver or termination without such consent
shall be null and void. In the event that the Guarantee shall be amended or
supplemented as herein permitted, the Guarantee, as so amended or supplemented,
shall continue to be subject to the provisions of the Assignment and this
Consent without the necessity of any further act by any of the parties hereto.
Nothing in this Section 4 shall be construed as limiting or otherwise affecting
in any way the Assignor's Excepted Rights or Shared Rights.

                  5. Continuing Obligations of the Assignor and the Lessee.
Neither the execution and delivery of the Assignment, nor any action or inaction
on the part of the Assignee shall impair or diminish any obligations of the
Assignor or the Lessee under the Lease or the Guarantors under the Guarantee,
and shall not impose on the Assignee (or its

                                                                               4

designee) any such obligations, nor shall it impose on the Assignee (or its
designee) a duty to produce Rents or cause the Assignee to be a mortgagee in
possession for any purpose.

                  6. Severability. If any provision or provisions, or if any
portion of any provision or provisions, in this Consent is found by a court of
law of competent jurisdiction to be in violation of any local, state or Federal
ordinance, statute, law, administrative or judicial decision, or public policy,
and if such court should declare such portion, provision or provisions to be
illegal, invalid, unlawful, void or unenforceable as written, then it is the
intent of the Lessee that such portion, provision or provisions shall be given
force to the fullest possible extent that they are legal, valid and enforceable,
that the remainder of this Consent shall be construed as if such illegal,
invalid, unlawful, void or unenforceable portion, provision or provisions were
not contained herein, and that the obligations of the Lessee under the remainder
of this Consent shall continue in full force and effect.

                  7. Governing Law. THIS CONSENT SHALL BE GOVERNED BY, AND
CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK,
EXCEPT AS TO MATTERS RELATING TO THE CREATION OF LIENS AND THE EXERCISE OF
REMEDIES WITH RESPECT
THERETO, WHICH SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE IN WHICH THE
EQUIPMENT IS LOCATED.


                  IN WITNESS WHEREOF, the Lessee and the Guarantors have caused
this Consent to be duly executed as of the date first written above.

exist at any time, and will, at its own cost and expense, promptly take such
action as may be necessary duly to discharge, or to cause to be discharged, all
Lessor Liens on the Equipment attributable to it or any of its Affiliates;
provided, however, that the Investor, the Trust and the Trust Company shall not
be required to so discharge any such Lessor Lien while the same is being
contested in good faith by appropriate proceedings diligently prosecuted so long
as such proceedings shall not cause Lessee or any other party hereto to be in
default under any of the Operative Documents and shall not involve any material
danger of impairment of the Liens of the Security Documents or of the sale,
forfeiture or loss of, and shall not materially interfere with the use or
disposition of, the Equipment or title thereto or any interest therein or the
payment of Rent.

                  (b) Trust Agreement. Without prejudice to any right under the
Trust Agreement of the Trust Company to resign, or the Investor's right under

Investor and the Trust Company hereby agrees with the Lessee and the Agent (i)
not to terminate or revoke the trust created by the Trust Agreement except as
permitted by the Trust Agreement, (ii) not to amend, supplement, terminate or
revoke or otherwise modify any provision of the Trust Agreement without the

amendment to the Trust Agreement within thirty (30) days after such amendment is

owner trustee may be appointed, and a corporation may become the owner trustee

other activity, or hold title to any assets other than pursuant to or under the

any of the acts set forth in this paragraph.

                  (g) Change of Chief Place of Business. The Trust shall give
prompt prior notice to the Lessee and the Agent if the Trust's chief place of
business or chief executive office, or the office where the records concerning

its name.

continuing, none of the Lenders, the Trust Company, the Lessor, the Agent nor

lease, assign, transfer or otherwise dispose of any of its property, business or

application of all sales proceeds pursuant to Section 8 of the Credit Agreement)
there remains any outstanding principal or accrued and unpaid interest under the
Tranche B Notes (the aggregate amount of such outstanding principal, the

Date the Investor shall pay to the Agent an amount up to the amount of the
Tranche B Deficit to be applied pursuant to Section 8 of the Credit Agreement,
but in no event greater than the Marketing Period Equity Return received by

                  9.3 Amendment of Certain Documents. The Agent, for itself and
on behalf of the Lenders, hereby agrees for the benefit of the Trust and the
Investor that it will not amend, alter or otherwise modify, or consent to any
amendment, alteration or modification of, the Lease (including the definitions

Trust and the Investor, as the case may be, if such amendment, alteration or
modification would adversely affect the interests of the Trust or the Investor.
Provisions requiring consent, include any amendment, alteration or modification
that would release the Lessee from any of its obligations in respect of the

Guarantee Amount or the Purchase Option Price or any other payments in respect
of the Equipment as set forth in the Lease, or amend the provisions of Section 8

that if at any time either the Lessor or the Investor receives any proceeds as a
result, directly or indirectly, of any Casualty or Condemnation with respect to
the Equipment which the Lessor is entitled to retain and hold in accordance with
the terms of the Lease, the Lessor and the Investor agree that they will
promptly deposit such amounts in an account with the Agent. The Lessor and the

                  11.2 Effect of Transfer. From and after any transfer effected

extent of such transfer, from its liability hereunder and under the other

after the date of such transfer; provided, however, that any transferor Investor
shall remain liable under the Trust Agreement to the extent that the transferee
Investor shall not have assumed the obligations of the transferor Investor

                                                                              26



Investor as above provided, any such transferee shall assume the obligations of
the same entity, and the Lessor or Investor, as the case may be, and shall be
deemed the "same entity", as the case may be, for all purposes of such documents
and each reference herein to the transferor shall thereafter be deemed a
reference to such transferee for all purposes, except as provided in the
preceding sentence. Notwithstanding any transfer of all or a portion of the
transferor's interest as provided in this Section 11, the transferor shall be
entitled to all benefits accrued and all rights vested prior to such transfer
including rights to indemnification under any such document.


                           SECTION 12. INDEMNIFICATION

                  12.1 General Indemnity. The Lessee, hereby assumes liability
for and agrees to defend, indemnify and hold harmless each Indemnified Person on
an After Tax Basis from and against any Claims which may be imposed on, incurred
by or asserted against an Indemnified Person in any way relating to or arising
out of (a) the financing, refinancing, purchase, acceptance, rejection,
ownership, design, delivery, acceptance, nondelivery, leasing, subleasing,
possession, use, operation, repair, modification, transportation, condition,
sale, return, repossession (whether by summary proceedings or otherwise), or any
other disposition of the Equipment or any part thereof; (b) any latent or other
defects in any piece of Equipment whether or not discoverable by an Indemnified
Person or the Lessee; (c) a violation of Environmental Laws, Environmental
Claims or other loss of or damage relating to the Equipment; (d) the Operative
Agreements, or any transaction contemplated thereby; (e) any breach by the
Lessee of any of its representations or warranties under the Operative
Agreements or failure by the Lessee to perform or observe any covenant or
agreement to be performed by it under any of the Operative Agreements; and (f)
personal injury, death or property damage relating to the Equipment, including
Claims based on strict liability in tort; but in any event excluding (v) Claims
to the extent such Claims arise solely out of the gross negligence or willful
misconduct of such Indemnified Person, (w) Claims to the extent such Claims
arise solely out of events occurring after Lessee's discharge of all its
obligations under the Lease or (x) any Taxes including any Claim (or any portion
of a Claim) made upon an Indemnified Person by a third party that at its origin
is based upon a Tax (other than amounts necessary to make any payments hereunder
on an After Tax Basis, where the Lessee is otherwise specifically required to
make such payments on an After Tax Basis), (y) legal proceedings commenced
against an Indemnified Person by any security holder or creditor solely in its
capacity as such, or (z) legal proceedings commenced against an Indemnified
Person by any other Indemnified Person or by any transferee of an Indemnified
Person. The Lessee shall be entitled to control, and shall assume full
responsibility for the defense of any Claim; provided, however, that the Trust,
the Trust Company, the Agent and the Investor named in such Claim, may each
retain separate counsel at the expense of the Lessee in the event of and to the
extent of an actual conflict or a potential conflict. The Lessee and each
Indemnified Person agree to give each other prompt



<PAGE>   31

                                                                              27



written notice of any Claim hereby indemnified against but the giving of any
such notice by an Indemnified Person shall not be a condition to the Lessee's
obligations under this Section 12.1, except to the extent failure to give such
notice materially prejudices Lessee's rights hereunder or with respect to the
defense or settlement of such Claim. After an Indemnified Person has been fully
indemnified for a Claim pursuant to this Section 12.1, and so long as no Lease
Event of Default shall have occurred and be continuing, the Lessee shall be
subrogated to any right of such Indemnified Person with respect to such Claim.
None of the Indemnified Persons shall settle a Claim without the prior written
consent of the Lessee, which consent shall not be unreasonably withheld or
delayed.

                  12.2 General Tax Indemnity. (a) The Lessee shall pay and
assume liability for, and does hereby agree to indemnify, protect and defend the
Equipment and all Tax Indemnitees, and hold them harmless against, all
Impositions on an After Tax Basis.

                  (b) Provided that no Default or Event of Default has occurred
and is continuing, if any Tax Indemnitee obtains a refund or a reduction in a
liability (but only if such reduction relates to a Tax not otherwise
indemnifiable hereunder and has not been taken into account in determining the
amount of a payment on an After Tax Basis) as a result of any Imposition paid or
reimbursed by the Lessee (in whole or in part), such Tax Indemnitee shall
promptly pay to the Lessee the lesser of (x) the amount of such refund or
reduction in liability and (y) the amount previously so paid or advanced by the
Lessee, in each case net of reasonable expenses not already paid or reimbursed
by the Lessee.

                  (c)(i) Subject to the terms of Section 12.2(g), the Lessee
shall pay or cause to be paid all Impositions directly to the taxing authorities
where feasible and otherwise to the Tax Indemnitee, as appropriate, and the
Lessee shall at its own expense, upon such Tax Indemnitee's reasonable request,
furnish to such Tax Indemnitee copies of official receipts or other satisfactory
proof evidencing such payment.

                  (ii) In the case of Impositions for which no contest is
conducted pursuant to Section 12.2(g) and which the Lessee pays directly to the
taxing authorities, the Lessee shall pay such Impositions prior to the latest
time permitted by the relevant taxing authority for timely payment. In the case
of Impositions for which the Lessee reimburses a Tax Indemnitee, the Lessee
shall do so within twenty (20) days after receipt by the Lessee of demand by
such Tax Indemnitee describing in reasonable detail the nature of the Imposition
and the basis for the demand (including the computation of the amount payable),
but in no event shall the Lessee be required to pay such reimbursement prior to
15 days before the latest time permitted by the relevant taxing authority for
timely payment. In the case of Impositions for which a contest is conducted
pursuant to Section 12.2(g), the Lessee shall pay such Impositions or reimburse
such Tax Indemnitee for such Impositions, to the extent not previously paid or
reimbursed pursuant

                                                                              28



to subsection (a), prior to the latest time permitted by the relevant taxing
authority for timely payment after conclusion of all contests under Section
12.2(g).

                 (iii) Impositions imposed with respect to a piece of Equipment
for a billing period during which the Lease expires or terminates with respect
to such Equipment (unless the Lessee has exercised the Purchase Option with
respect to the Equipment) shall be adjusted and prorated on a daily basis
between the Lessee and the Lessor, whether or not such Imposition is imposed
before or after such expiration or termination and each party shall pay or
reimburse the other for each party's pro rata share thereof.

                 (iv) At the Lessee's request, the amount of any indemnification
payment by the Lessee pursuant to subsection (a) shall be verified and certified
by an independent public accounting firm mutually acceptable to the Lessee and
the Tax Indemnitee. The fees and expenses of such independent public accounting
firm shall be paid by the Lessee unless such verification shall result in an
adjustment in the Lessee's favor of 10% or more of the payment as computed by
such Tax Indemnitee, in which case such fee shall be paid by such Tax
Indemnitee.

                  (d)(i) The Lessee shall be responsible for preparing and
filing any real and personal property or ad valorem tax returns in respect of
the Equipment. In case any other report or tax return shall be required to be
made with respect to any obligations of the Lessee under or arising out of
subsection (a) and of which the Lessee has knowledge, the Lessee, at its sole
cost and expense, shall notify the relevant Tax Indemnitee of such requirement
and (except if such Tax Indemnitee notifies the Lessee that such Person intends
to file such report or return) (A) to the extent required or permitted by and
consistent with Legal Requirements, make and file in its own name such return,
statement or report; and (B) 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 the Lessee under or
arising out of subsection (a), provide such Tax Indemnitee at the Lessee's
expense with information sufficient to permit such return, statement or report
to be properly made with respect to any obligations of the Lessee under or
arising out of subsection (a). Such Tax Indemnitee shall, upon the Lessee's
request and at the Lessee's expense, provide any data maintained by such Tax
Indemnitee (and not otherwise within the control of the Lessee) with respect to
the Equipment which the Lessee may reasonably require to prepare any required
tax returns or reports;

                  (e) If as a result of the payment or reimbursement by the
Lessee of any expenses of a Tax Indemnitee or the payment of any Transaction
Expenses incurred in connection with the transactions contemplated by the
Operative Agreements, any Tax

                                                                              29



Indemnitee, shall suffer a net increase in any federal, state or local income
tax liability, the Lessee shall indemnify such Tax Indemnitees (without
duplication of any indemnification required by subsection (a)) on an After Tax
Basis for the amount of such increase. The calculation of any such net increase
shall take into account any current or future tax savings realized or reasonably
expected to be realized by such Tax Indemnitees, in respect thereof, as well as
any interest, penalties and additions to tax payable by such Tax Indemnitees, in
respect thereof;

                  (f) As between the Lessee and the Lessor, the Lessee shall be
responsible for, and the Lessee shall indemnify and hold harmless the Trust
Company in its individual capacity and as the Lessor (without duplication of any
indemnification required by subsection (a)) on an After Tax Basis against, any
obligation for United States withholding taxes imposed in respect of the
interest payable on the Notes to the extent, but only to the extent, Lessor has
actually paid funds to a taxing authority with respect to such withholding taxes
(and, if the Lessor receives a demand for such payment from any taxing
authority, the Lessee shall discharge such demand on behalf of the Lessor);

                  (g)(i) If a written claim is made against any Tax Indemnitee
or if any proceeding shall be commenced against such Tax Indemnitee (including a
written notice of such proceeding), for any Impositions, such Tax Indemnitee
shall promptly notify Lessee in writing and shall not take action with respect
to such claim or proceeding without the consent of Lessee for thirty (30) days
after the receipt of such notice by Lessee; provided, that, in the case of any
such claim or proceeding, if action shall be required by law or regulation to be
taken prior to the end of such 30-day period, such Tax Indemnitee shall, in such
notice to Lessee, inform Lessee, and no action shall be taken with respect to
such claim or proceeding without the consent of Lessee before the end of such
shorter period; provided, further, that the failure of such Tax Indemnitee to
give the notices referred to this sentence shall not diminish Lessee's
obligation hereunder except to the extent such failure materially adversely
affects Lessee in contesting all or part of such claim.

                  (ii) If, within thirty (30) days of receipt of such notice
from the Tax Indemnitee (or such shorter period as the Tax Indemnitee has
noticed Lessee is required by law or regulation for the Tax Indemnitee to
commence such contest), Lessee shall request in writing that such Tax Indemnitee
contest such Imposition, the Tax Indemnitee shall, at the expense of Lessee, in
good faith conduct and control such contest (including, without limitation, by
pursuit of appeals) relating to the validity, applicability or amount of such
Impositions (provided, however, that (A) if such contest can be pursued
independently from any other proceeding involving a tax liability of such Tax
Indemnitee, the Tax Indemnitee, at Lessee's request, shall allow Lessee to
conduct and control such contest and (B) in the case of any contest that Lessee
is not entitled to control, the Tax Indemnitee may request Lessee to conduct and
control such contest if possible or


<PAGE>   34

                                                                              30



permissible under applicable law or regulation) by, in the sole discretion of
the Person conducting and controlling such contest, (1) resisting payment
thereof, (2) not paying the same except under protest, if protest is necessary
and proper, (3) if the payment be made, using reasonable efforts to obtain a
refund thereof in appropriate administrative and judicial proceedings, or (4)
taking such other action as is reasonably requested by Lessee from time to time.

                 (iii) The party controlling any contest shall consult in good
faith with the non-controlling party and shall keep the non-controlling party
reasonably informed as to the conduct of such contest; provided that all
decisions ultimately shall be made in the sole discretion of the controlling
party. The parties agree that an Tax Indemnitee may at any time decline to take
further action with respect to the contest of any Imposition and may settle such
contest if such Tax Indemnitee shall waive its rights to any indemnity from
Lessee that otherwise would be payable in respect of such claim (and any future
claim by any taxing authority with respect to other taxable periods that are
based, in whole or in part, upon the resolution of such claim) and shall pay to
Lessee any amount previously paid or advanced by Lessee pursuant to this Section
12.2 by way of indemnification or advance for the payment of an Imposition, and
no other then future liability of the Lessee is likely with respect to such
Imposition.

                 (iv) Notwithstanding the foregoing provisions of this Section
12.2, a Tax Indemnitee shall not be required to take any action and Lessee shall
not be permitted to contest any Impositions in its own name or that of the Tax
Indemnitee unless (A) Lessee shall have agreed to pay and shall pay to such Tax
Indemnitee on demand and on an After Tax Basis all reasonable costs, losses and
expenses that such Tax Indemnitee actually incurs in connection with contesting
such Impositions, including, without limitation, all reasonable legal,
accounting and investigatory fees and disbursements, (B) in the case of a claim
that must be pursued in the name of an Tax Indemnitee (or an Affiliate thereof),
the amount of the potential indemnity (taking into account all similar or
logically related claims that have been or could be raised in any audit
involving such Tax Indemnitee for which Lessee may be liable to pay an indemnity
under this Section 12.2) is more than $25,000, unless the pursuit of such
contest is in a manner mutually satisfactory to the Tax Indemnitee and the
Lessee, but in no event shall such right prevent the Lessee from prosecuting or
continuing such contest, (C) the Tax Indemnitee shall have reasonably determined
that the action to be taken will not result in any material danger of sale,
forfeiture or loss of any piece of Equipment, or any part thereof or interest
therein, will not interfere with the payment of Rent, and will not result in
risk of criminal liability, (D) if such contest shall involve the payment of the
Imposition prior to the contest, Lessee shall provide to the Tax Indemnitee an
interest-free advance in an amount equal to the Imposition that the Tax
Indemnitee is required to pay (with no additional net after-tax cost to such Tax
Indemnitee), (E) in the case of a claim that must be pursued in the name of an
Tax Indemnitee (or an Affiliate thereof), Lessee shall have provided to such Tax
Indemnitee an opinion of independent tax

                                                                              31



counsel selected by the Lessee and reasonably satisfactory to such Tax
Indemnitee stating that a reasonable basis exists to contest such claim (or, in
the case of an appeal of an adverse determination, an opinion of such counsel to
the effect that there is substantial authority for the position asserted in such
appeal) and (F) no Event of Default shall have occurred and be continuing. In no
event shall a Tax Indemnitee be required to appeal an adverse judicial
determination to the United State Supreme Court. In addition, a Tax Indemnitee
shall not be required to contest any claim in its name (or that of an Affiliate)
if the subject matter thereof shall be of a continuing nature and shall have
previously been decided adversely by a court of competent jurisdiction pursuant
to the contest provisions of this Section 12.2, unless there shall have been a
change in law (or interpretation thereof) and the shall Tax Indemnitee have
received, at the Lessee's expense, an opinion of independent tax counsel
selected by the Lessee and reasonably acceptable to the Tax Indemnitee stating
that as a result of such change in law (or interpretation thereof), it is more
likely than not that the Tax Indemnitee will prevail in such contest.


                            SECTION 13. MISCELLANEOUS

                  13.1 Survival of Agreements. The representations, warranties,

Equipment or any interest of the Investor in the Trust, the payment of the Notes

                  13.8    GOVERNING LAW.  THIS AGREEMENT SHALL BE GOVERNED
BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAWS
OF THE STATE OF NEW YORK.

                  13.9 Severability. Any provision of this Agreement that is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

                  13.10 Liability Limited. The Lessee and the Investor each
acknowledge and agree that the Trust Company is (except as otherwise expressly
provided herein or therein) entering into this Agreement and the other Operative
Agreements to which it is a party (other than the Trust Agreement), solely in
its capacity as trustee under the Trust Agreement and not in its individual
capacity and that Trust Company shall not be liable or accountable under any
circumstances whatsoever in its individual capacity for or on account of any
statements, representations, warranties, covenants or obligations stated to be
those of the Trust, except for its own gross negligence or willful misconduct
and as otherwise expressly provided herein or in the other Operative Agreements.

                  13.11 Rights of Lessee. Notwithstanding any provision of the
Operative Agreements, if at any time all obligations (i) of the Trust under the
Credit Agreement and the Security Documents and (ii) of the Lessee under the
Operative Agreements have in each case been satisfied or discharged in full,
then the Lessee shall be entitled to (a) terminate the Lease (to the extent not
previously terminated) and (b) receive all amounts then held under the Operative
Agreements and all proceeds with respect to the Equipment. Upon the fulfillment
of the obligations contained in clauses (i) and (ii) above, the Lessor shall
transfer to the Lessee all of its right, title and interest in and to the
Equipment (to the extent not previously transferred to the Lessee in accordance
with the Lease) and any amounts or proceeds referred to in the foregoing clause
(b) shall be paid over to the Lessee.

                  13.12 Further Assurances. The parties hereto shall promptly
cause to be taken, executed, acknowledged or delivered, at the sole expense of
the Lessee (other than with respect to the removal of Lessor Liens), all such
further acts, conveyances, documents and assurances as the other parties may
from time to time reasonably request in order to carry out and effectuate the
intent and purposes of this Agreement, the other Operative Agreements and the
transactions contemplated hereby and thereby (including, without limitation, the
preparation, execution and filing of any and all Uniform Commercial Code
financing statements and other filings or registrations which the parties hereto
may from time to time request to be filed or effected). The Lessee, at its own
expense, shall take such action as may be reasonably requested in order

                                                                              35



to maintain and protect all security interests provided for hereunder or under
any other Operative Agreement.

                  13.13 Successors and Assigns. This Agreement shall be binding
upon and inure to the benefit of the parties hereto and their respective
successors and assigns.

                  13.14 No Representation or Warranty. Nothing contained herein,
in any other Operative Agreement or in any other materials delivered to the
Lessee in connection with the transactions contemplated hereby or thereby shall
be deemed a representation or warranty by the Agent or the Arranger or any of
their Affiliates as to the proper accounting treatment or tax treatment that
should be afforded to the Lease and the Lessor's ownership of the Equipment and
the Agent expressly disclaims any representation or warranty with respect to
such matters.

                  13.15 Highest Lawful Rate. It is the intention of the parties
hereto conform strictly to applicable usury laws and, anything herein to the
contrary notwithstanding, the obligations of the Lessee, the Lessor or the
Investor or any other party under any Operative Agreement, shall be subject to
the limitation that payments of interest or of other amounts constituting
interest shall not be required to the extent that receipt thereof would be in
excess of the Highest Lawful Rate, or otherwise contrary to provisions of law
applicable to the recipient limiting rates of interest which may be charged or
collected by the recipient. Accordingly, if the transactions or the amount paid
or otherwise agreed to be paid for the use, forbearance or detention of money
under this Agreement, the Lease and any other Operative Agreement would exceed
the Highest Lawful Rate or otherwise be usurious with respect to the recipient
of any such amount, then, in that event, notwithstanding anything to the
contrary in this Agreement, the Lease or any other Operative Agreement, it is
agreed as follows as to the recipient of any such amount:

                  (a) the provisions of this Section 13.15 shall govern and
control over any other provision in this Agreement, the Lease and any other
Operative Agreement and each provision set forth therein is hereby so limited;

                  (b) the aggregate of all consideration which constitutes
interest that is contracted for, charged or received under this Agreement, the
Lease, or any other Operative Agreement shall under no circumstances exceed the
maximum amount of interest allowed by any Requirement of Law (such maximum
lawful interest rate, if any, with respect to such Lender herein called the
"Highest Lawful Rate"), and all amounts owed under this Agreement, the Lease and
any other Operative Agreement shall be held subject to reduction and (i) the
amount of interest which would otherwise be payable to the recipient hereunder
and under the Lease, the Loan Documents and any other Operative Agreement, shall
be automatically reduced to the amount allowed under any Requirement of Law and
(ii) any unearned interest paid in excess of

                                                                              36



the Highest Lawful Rate shall be credited to the payor by the recipient (or, if
such consideration shall have been paid in full, refunded to the payee);

                  (c) all sums paid, or agreed to be paid for the use,
forbearance and detention of the money under this Agreement, the Lease, or any
other Operative Agreement shall, to the extent permitted by any Requirement of
Law, be amortized, prorated, allocated and spread throughout the full term of
such indebtedness until payment in full so that the actual rate of interest is
uniform throughout the full term thereof; and

                  (d) if at any time the interest, together with any other fees,
late charges and other sums payable pursuant to or in connection with this
Agreement, the Lease, and any other Operative Agreement executed in connection
herewith or therewith, and deemed interest under any Requirement of Law exceeds
that amount which would have accrued at the Highest Lawful Rate, the amount of
interest and any such fees, charges and sums to accrue to the recipient of such
interest, fees, charges and sums pursuant to the Operative Agreement shall be
limited, notwithstanding anything to the contrary in the Operative Agreement to
that amount which would have accrued at the Highest Lawful Rate for the
recipient, but any subsequent reductions, as applicable, shall not reduce the
interest to accrue pursuant to the Operative Agreement below the recipient's
Highest Lawful Rate until the total amount of interest payable to the recipient
(including all consideration which constitutes interest) equals the amount of
interest which would have been payable to the recipient (including all
consideration which constitutes interest), plus the amount of fees which would
have been received but for the effect of this Section 13.15.

                  13.16 Waiver. EACH PARTY HERETO FOR THE BENEFIT OF THE PARTIES
HERETO AND THE GUARANTORS HEREBY IRREVOCABLY AND UNCONDITIONALLY WAVES, TO THE
EXTENT NOT PROHIBITED BY LAW, ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY
LEGAL ACTION OR PROCEEDING PURSUANT TO THE OPERATIVE AGREEMENTS ANY SPECIAL,
EXEMPLARY, PUNITIVE, INDIRECT OR CONSEQUENTIAL DAMAGES.

EQUIPMENT TRUST 1998A, a Delaware business trust (the "Borrower"), in favor of
THE CHASE MANHATTAN BANK, as Agent (in such capacity, the "Agent") for the
Lenders parties to the Credit Agreement, dated as of the date hereof (as
amended, supplemented or otherwise modified from time to time, the "Credit
Agreement"), among the Borrower, the Agent and such Lenders.


                             Preliminary Statement


                  A. Pursuant to the Credit Agreement, the Lenders have
severally agreed to make Loans to the Borrower upon the terms and subject to
the conditions set forth therein; and

                  B. It is a condition precedent to the obligation of the

Agreement to the Agent for the ratable benefit of the Lenders.

                  NOW, THEREFORE, in consideration of the premises and to induce
the Agent and the Lenders to enter into the Credit Agreement and to induce the

              "Collateral":  as defined in Section .

              "Equipment":  the equipment set forth on Schedule 1 annexed
         hereto, and all other tangible personal property now or hereafter
         acquired by the Borrower, together with any and all accessions,
         additions, improvements, substitutions and replacements thereto and

              "Obligations":  shall mean the Guaranteed Obligations.

              "Proceeds":  as defined in the Code.

         2. Grant of Security Interest. As collateral security for the prompt
and complete payment and performance when due (whether at the stated maturity,
by acceleration or otherwise) of the Obligations, the Borrower hereby grants to
the Agent for the ratable benefit of the Lenders a security interest in all of
its respective right, title and interest, whether the same be goods, fixtures,
equipment, general intangibles, accounts or chattel paper, in and to (a) the
Equipment, (b) rights and interests of Borrower as Lessor pursuant to the Lease,
(c) the proceeds of the Houston Pipeline Purchase Option, (d) all books and
records pertaining to the foregoing, (e) all warranties and guarantees given by
any Person with respect to any of the foregoing, as well as all chooses in

the extent not otherwise included, all Proceeds and products of the foregoing,
in each case whether now existing or hereafter acquired (collectively, the
"Collateral"), subject to the rights of the Lessee, as Lessee under the Lease,
so long as no Lease Event of Default has occurred and is continuing.

         3.  Representations and Warranties.

         3.1 Equipment . The Borrower hereby represents and warrants that, the
Equipment will be kept at the locations listed on Schedule 1 subject only to the
Lessee's rights to relocate the Equipment as provided for in the Operative
Agreements.

or otherwise been terminated:

         4.1 Further Documentation . At any time and from time to time, upon the

                                                                               3


actions as the Agent may reasonably request for the purpose of obtaining or
preserving the full benefits of this Agreement and of the rights and powers
herein granted, including, without limitation, the filing of any financing or
continuation statements under the Uniform Commercial Code in effect in any
jurisdiction with respect to the security interests created hereby.

         4.2 Changes in Locations . 20. Except with respect to the rights of the
Lessee under the Operative Agreements, the Borrower will not permit any of the
Equipment to be kept at a location other than those listed on Schedule 1; and

         (b) The Borrower will not change the location of its chief executive
offices from that specified in Section 3.2.

         4.3 Change in Name. The Borrower will not change its name, identity or
structure to such an extent that any financing statement filed by the Agent in
connection with this Agreement would become seriously misleading, unless they
shall have given the Agent at least 30 days' prior written notice of such
change.

         4.4 Further Identification of Collateral . The Borrower will cause the
Lessee to furnish to the Agent from time to time statements and schedules
further identifying and describing the Collateral and its location and such
other reports in connection with the Collateral as the Agent may reasonably
request, all in reasonable detail.

         5.  Remedies.

         5.1 Code Remedies . If a Credit Agreement Event of Default shall occur
and be continuing, the Agent, on behalf of the Lenders, may exercise, in
addition to all other rights and remedies granted to them in this Agreement and
in any other instrument or agreement securing, evidencing or relating to the
Obligations, all rights and remedies of a secured party under the Code. Without
limiting the generality of the foregoing, the Agent, without demand of
performance or other demand, presentment, protest, advertisement or notice of
any kind (except any notice required by law or as referred to below) to or upon
the Borrower, the Lessee or any other Person (all and each of which demands,
defenses, advertisements and notices are hereby waived to the extent permitted
by law), may in such circumstances forthwith collect, receive, appropriate and
realize upon the Collateral, or any part thereof, and/or may forthwith sell,
lease, assign, give an option or options to purchase, or otherwise dispose of
and deliver the Collateral or any part thereof (or contract to do any of the
foregoing), in one or more parcels at public or private sale or sales, at any
exchange, broker's board or office of the Agent or any Lender or elsewhere upon
such terms and conditions as it may deem advisable and at such prices as it may
deem best, for cash or on credit or for future delivery without assumption of
any credit risk, but subject to the rights of the Lessee under the Lease so long
as no Lease Event of Default shall have occurred and be continuing. The Agent or
any Lender shall have the right upon any such public sale or sales, and, to the
extent permitted by law, upon any such private sale or sales, to purchase the
whole or any part of the Collateral so sold, free of any right or equity of
redemption in the Borrower, which right or equity is hereby waived or released
to the extent permitted by 

<PAGE>   4
                                                                              4 

law. The Borrower further agrees, at the Agent's request, to assemble the
Collateral and make it available to the Agent at places which the Agent shall
reasonably select. The Agent shall apply the net proceeds of any action taken
by it pursuant to this subsection, after deducting all reasonable costs and
expenses of every kind incurred in connection therewith or incidental to the
care or safekeeping of any of the Collateral or in any way relating to the
Collateral or the rights of the Agent and the Lenders hereunder, including,
without limitation, reasonable attorneys' fees and disbursements, to the
payment in whole or in part of the Obligations, in accordance with Section 8.2
of the Credit Agreement, and only after such application and after the payment
by the Agent of any other amount required by any provision of law, including,
without limitation, Section 9-504(1)(c) of the Code, need the Agent account for
the surplus, if any, to the Borrower. To the extent permitted by applicable
law, the Borrower waives all claims, damages and demands it may acquire against
the Agent or any Lender arising out of the exercise by them of any rights
hereunder. If any notice of a proposed sale or other disposition of Collateral
shall be required by law, such notice shall be deemed reasonable and proper if
given at least 10 days before such sale or other disposition. The Agent agrees
that if it shall proceed to foreclose the Lien of this Agreement, it shall, to
the extent that it is entitled to do so hereunder and under the other Operative

any and all appropriate action and to execute any and all documents and
instruments which may be necessary or desirable to accomplish the purposes of
this Agreement, and, without limiting the generality of the foregoing, the
Borrower hereby gives the Agent the power and right, on behalf of the Borrower,

enforce any other right in respect of any Collateral; 33. defend any suit,
action or proceeding brought against the Borrower with respect to any
Collateral; 34. settle, compromise or adjust any such suit, action or
proceeding and, in connection therewith, to give such discharges or releases as
the Agent may deem appropriate; and 35. generally, sell, transfer, pledge and
make any agreement with respect to or otherwise deal with any of the Collateral
as fully and completely as though the Agent were the absolute owner thereof for
all purposes, and do, at the Agent's option and the Borrower's expense, at any
time, or from time to time, all acts and things which the Agent deems necessary
to protect, preserve or realize upon the Collateral and the Agent's and the
Lenders' security interests therein and to effect the intent of this Agreement,
all as fully and effectively as the Borrower might do.

         Anything in this subsection to the contrary notwithstanding, the Agent
agrees that it will not exercise any rights under the power of attorney provided
for in this subsection unless a Credit Agreement Event of Default shall have
occurred and be continuing.

         6.2 Performance by Agent of Borrower's Obligations . If the Borrower
fails to perform or comply with any of its agreements contained herein, the
Agent, at its option, but without any obligation so to do, may perform or
comply, or otherwise cause performance or compliance, with such agreement.

         6.3 Borrower's Reimbursement Obligation . The expenses of the Agent
incurred in connection with actions undertaken as provided in this Section,

authorizations and agencies contained in this Agreement are coupled with an
interest and are irrevocable until this Agreement is terminated and the security

safekeeping and physical preservation of the Collateral in its possession, under
Section 9-207 of the Code or otherwise to the extent permitted by law, shall be
to deal with it in the same manner as the Agent deals with similar property for
its own account. Neither the Agent, any Lender nor any of their respective
officers, directors, employees or agents shall be liable for failure to demand,
collect or realize upon any of the Collateral or for any delay in doing so or
shall be under any obligation to sell or otherwise dispose of any Collateral
upon the request of the Borrower or any other Person or to take any other action
whatsoever with regard to the Collateral or any part thereof. The powers
conferred on the Agent and the Lenders hereunder are solely to protect the
Agent's and the Lenders' interests in the Collateral and shall not impose any
duty upon the Agent or any Lender to exercise any such powers. Neither the
Agent, the Lenders nor any of their officers, directors, employees or agents
shall be responsible to the Borrower for any act or failure to

                                                                               6

any Lender or any of their officers, directors, employees or agents.

         8.  Execution of Financing Statements. Pursuant to and to the extent
permitted by Section 9-402 of the Code, the Borrower authorizes the Agent to
file financing statements with respect to the Collateral without the signature
of the Borrower in such form and in such filing offices as the Agent reasonably
determines appropriate to perfect the security interests of the Agent under this
Agreement. A carbon, photographic or other reproduction of this Agreement shall
be sufficient as a financing statement for filing in any jurisdiction.

         9.  Authority of Agent. The Borrower acknowledges that the rights and
responsibilities of the Agent under this Agreement with respect to any action
taken by the Agent or the exercise or non-exercise by the Agent of any request,
judgment or other right or remedy provided for herein or resulting or arising
out of this Agreement shall, as between the Agent and the Lenders, be governed
by the Credit Agreement and by such other agreements with respect thereto as may
exist from time to time among them, but, as between the Agent and the Borrower,
the Agent shall be conclusively presumed to be acting as agent for the Lenders
with full and valid authority so to act or refrain from acting, and the Borrower
shall not be under any obligation, or entitlement, to make any inquiry
respecting such authority.

         10. Notices. Unless otherwise specifically provided herein, all
notices, requests and demands required or permitted by the terms hereof to be
given to any person shall be given pursuant to and in accordance with Section
13.3 of the Participation Agreement.

         11. Severability. Any provision of this Agreement which is prohibited
or unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

         12. Amendments in Writing; Cumulative Remedies.

         12.1 Amendments in Writing . None of the terms or provisions of this
Agreement may be waived, amended, supplemented or otherwise modified except by a
written instrument executed by the Borrower and the Agent, provided that any
provision of this Agreement imposing obligations on the Borrower may be waived
by the Agent in a written instrument executed by the Agent.

         12.2 Remedies Cumulative . The rights and remedies herein provided are
cumulative, may be exercised singly or concurrently and are not exclusive of any
other rights or remedies provided by law.

                  HANOVER COMPRESSOR COMPANY, a Delaware corporation ("Lessee")
hereby joins in the Security Agreement dated as of July 22, 1998 made by HANOVER
EQUIPMENT TRUST 1998A, as the Borrower in favor of The Chase Manhattan Bank, as
the Agent for the Lenders (the "Security Agreement") in order to, and HEREBY
GRANTS TO THE AGENT FOR THE RATABLE BENEFIT OF THE LENDERS A SECURITY INTEREST
IN all of its right, title and interest, if any, in and to the Collateral for
the purpose of securing the Obligations. Lessee acknowledges and agrees that,
upon the occurrence of a Credit Agreement Event of Default and subject to the
terms of the Lease, the Agent on behalf of the Lenders shall have the right to
exercise any and all of its remedies hereunder as against the Collateral.

                  Lessee agrees that if Lessee has any right, title, estate or
interest in the Collateral, Lessee is to that extent a guarantor or surety for
the benefit of the Agent and the Lenders. In such event, Lessee expressly agrees
that the rights of the Agent and the Lenders shall in no way be affected or
impaired by reason of the occurrence of any of the following events: (i) the
waiver by the Agent or the Lenders of the performance or observance by the
Borrower, Lessee or any other party of any terms of the Operative Agreements;
(ii) the extension, in whole or in part, of the time for payment by the Borrower
of any sums owing or payable under the Operative Agreements; (iii) any failure,
delay or inability of the Agent or the Lenders in enforcing any remedies or any
other provisions under the Operative Agreements; (iv) the occurrence of any
event described in Section 7.1(1) of the Credit Agreement; or (v) the inability
of the Borrower to perform (or the release of the Borrower's performance) under
the Operative Agreements due to any Legal Requirement. Notwithstanding the
foregoing, Lessee shall not have any personal liability under this Security
Agreement and Joinder in excess of its personal liability under the Guaranty and
the other Operative Agreements.

                  This Joinder shall be considered part of the Security
Agreement to which it is attached, and all references in the Operative
Agreements to the Security Agreement shall mean the Security Agreement together
with this Joinder.

                    HANOVER COMPRESSOR COMPLETES $200 MILLION
                      TRANSACTION TO FUND GROWTH STRATEGIES


HOUSTON, TX - July 22, 1998 -- Hanover Compressor Company (NYSE:HC) announced
today that it has completed a $200 million, 5 year lease transaction arranged by
Chase Securities Inc. The transaction has been structured as a sale lease back
of compression equipment with a newly formed Trust and will be accounted for as
an operating lease. Under the agreement, the compression equipment will be sold
to the Trust and leased back by Hanover for a 5 year period and will continue to
be deployed the Company's normal operating procedures. Additionally, Hanover has
the option to repurchase the equipment from the Trust at any time.

Proceeds from the transaction will be used to repay borrowings under the
Company's existing revolving credit facility. As of the completion of this
transaction, Hanover has $180 million of availability under its existing
revolving credit facility to fund the Company's ongoing working capital
requirements and expansion plans.

As a result of the transaction, Hanover's annualized depreciation expense will
decrease by approximately $7.5 million. The Company will incur annual operating
lease expense of approximately $14 million (or 7% of the $200 million sale
proceeds), an amount equivalent to the annual interest expense of the revolving
credit debt that was repaid as a result of the sale.

"This transaction represents an important component of our plan to expand
Hanover's cash flow, earnings and equity value," said Michael J. McGhan,
President and CEO of Hanover Compressor. "It allows Hanover to make better use
of its borrowing capacity by employing a degree of financial leverage that is
well supported by our strong cash flow at what we believe is an extremely
attractive cost of capital."

                                     -more-

"Importantly," Mr. McGhan continued, "we now have significantly enhanced both
our financial flexibility and our capability to fund Hanover's growth. Following
this transaction, our existing revolving credit facility is available to fund
activities associated with our stated, four-part growth strategy of expanding
domestic market share, increasing international penetration, facilitating
compression outsourcing through acquisition leaseback transactions, and
selectively pursuing industry Indeed, we've made important progress towards
achieving these goals, as we recently completed two regional company
acquisitions and two acquisition/leasebacks of customer-owned compressor fleets
(including one with a Canadian operator), representing an aggregate investment
by Hanover of approximately $30 million," McGhan added.

Hanover Compressor is the market leader in full service natural gas compression.
Natural gas compressors play a critical role in facilitating the distribution of
energy from its source to industrial, commercial and residential consumers.
Hanover provides this equipment on a rental, contract compression, maintenance,
and acquisition leaseback basis to natural gas production, processing and
transportation companies that are increasingly seeking outsourcing solutions. In
addition, Hanove specialized fabrication of compressors and production
equipment.
