                             W I T N E S S E T H:
                             - - - - - - - - - -

     WHEREAS, 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, to be evidenced by the Notes issued by the
Borrower under the Credit Agreement;

     WHEREAS, each Guarantor is a Qualified Subsidiary of the Borrower;

     WHEREAS, the proceeds of the Loans will be used in part to enable the
Borrower to make valuable transfers (as determined as provided herein) to some
of the Guarantors in connection with the operation of their respective
businesses;

     WHEREAS, it is a condition precedent to the obligation of the Lenders to
amend and restate the Credit Agreement and to make their respective Loans to the
Borrower under the Credit Agreement that the Guarantors shall have executed and
delivered this Guarantee to the Administrative Agent for the ratable benefit of
the Lenders.

     NOW, THEREFORE, in consideration of the premises and to induce the
Administrative Agent and the Lenders to amend and restate the Credit Agreement
and to induce the Lenders to make their respective loans to the Borrower under
the Credit Agreement, the Guarantors hereby agree with the Administrative Agent,
for the ratable benefit of the Lenders, as follows:


     1    Defined Terms. (a) Unless otherwise defined herein, terms defined in
          -------------
the Credit Agreement and used herein shall have the meanings given to them in
the Credit Agreement.


     (a)  As used herein, "Obligations" means the collective reference to the
                           -----------
unpaid principal of and interest on any outstanding Loans and all other
obligations and liabilities of the Borrower to the Administrative Agent or the
Lenders (including, without limitation, interest accruing at the then applicable
rate provided in the Credit Agreement after the maturity of the Loans and
interest accruing at the then applicable rate provided in the Credit Agreement
after the filing of any petition in bankruptcy, or the commencement of any
insolvency, reorganization or like proceeding, relating to the Borrower, whether
or not a claim for post-filing or post-petition
<PAGE>

interest is allowed in such proceeding), whether direct or indirect, absolute or
contingent, due or to become due, now existing or hereafter incurred, which may
arise under, out of, or in connection with, the Credit Agreement, the Notes, the
Letters of Credit, the other Loan Documents or any other document made,
delivered or given in connection therewith, whether on account of principal,
interest, reimbursement obligations, fees, indemnities, costs, expenses or
otherwise (including, without limitation, all fees and disbursements of counsel
to the Administrative Agent or to the Lenders that are required to be paid by
the Borrower or the Guarantor pursuant to the terms of the Credit Agreement or
this Agreement or any other Loan Document).

     (b)  The words "hereof," "herein" and "hereunder" and words of similar
import when used in this Guarantee shall refer to this Guarantee as a whole and
not to any particular provision of this Guarantee, and section and paragraph
references are to this Guarantee unless otherwise specified.

     (c)  The meanings given to terms defined herein shall be equally applicable
to both the singular and plural forms of such terms.

     2    Guarantee (a) Subject to the provisions of paragraph 2(b), each of the
          ---------
Guarantors hereby, jointly and severally, unconditionally and irrevocably,
guarantees to the Administrative Agent, for the ratable benefit of the Lenders
and their respective successors, indorsees, transferees and assigns, the prompt
and complete payment and performance by the Borrower when due (whether at the
stated maturity, by acceleration or otherwise) of the Obligations.

     (a)  Anything herein or in any other Loan Document to the contrary
notwithstanding, the maximum liability of each Guarantor hereunder and under the
other Loan Documents shall in no event exceed the amount which can be guaranteed
by such Guarantor under applicable federal and state laws relating to the
insolvency of debtors.

     (b)  Each Guarantor further agrees to pay any and all expenses (including,
without limitation, all fees and disbursements of counsel) which may be paid or
incurred by the Administrative Agent or any Lender in enforcing, or obtaining
advice of counsel in respect of, any rights with respect to, or collecting, any
or all of the Obligations and/or enforcing any rights with respect to, or
collecting against, such Guarantor under this Guarantee. This Guarantee shall
remain in full force and effect until the Obligations are paid in full and the
Commitments are terminated, notwithstanding that from time to time prior thereto
the Borrower may be free from any Obligations.

     (c)  Each Guarantor agrees that the Obligations may at any time and from
time to time exceed the amount of the liability of such Guarantor hereunder
without impairing this Guarantee or affecting the rights and remedies of the
Administrative Agent or any Lender hereunder.

     (d)  No payment or payments made by the Borrower, any of the Guarantors,
any other guarantor or any other Person or received or collected by the
Administrative Agent or any Lender from the Borrower, any of the Guarantors, any
other guarantor or any other Person by virtue of any action or proceeding or any
set-off or appropriation or application at any time or from time to time in
reduction of or in payment of the Obligations shall be deemed to modify, reduce,
release or otherwise affect the liability of any Guarantor hereunder which
shall, notwithstanding any such payment or payments other than payments made by
such Guarantor in
<PAGE>

respect of the Obligations or payments received or collected from such Guarantor
in respect of the Obligations, remain liable for the Obligations up to the
maximum liability of such Guarantor hereunder until the Obligations are paid in
full and the Commitments are terminated.

     3    Right of Contribution. Each Guarantor hereby agrees that to the extent
          ---------------------
that a Guarantor shall have paid more than its proportionate share of any
payment made hereunder, such Guarantor shall be entitled to seek and receive
contribution from and against any other Guarantor hereunder who has not paid its
proportionate share of such payment. Each Guarantor's right of contribution
shall be subject to the terms and conditions of Section 5 hereof. The provisions
of this Section shall in no respect limit the obligations and liabilities of any
Guarantor to the Administrative Agent and the Lenders, and each Guarantor shall
remain liable to the Administrative Agent and the Lenders for the full amount
guaranteed by such Guarantor hereunder.

     4    Right of Set-off. Upon the occurrence of any Event of Default, each
          ----------------
Guarantor hereby irrevocably authorizes each Lender at any time and from time to
time without notice to such Guarantor or any other Guarantor, any such notice
being expressly waived by each Guarantor, to set-off and appropriate and apply
any and all deposits (general or special, time or demand, provisional or final),
in any currency, and any other credits, indebtedness or claims, in any currency,
in each case whether direct or indirect, absolute or contingent, matured or
unmatured, at any time held or owing by such Lender to or for the credit or the
account of such Guarantor, or any part thereof in such amounts as such Lender
may elect, against and on account of the obligations and liabilities of such
Guarantor to such Lender hereunder and claims of every nature and description of
such Lender against such Guarantor, in any currency, whether arising hereunder,
under the Credit Agreement, any Note, any Letter of Credit or any Loan Document,
as such Lender may elect, whether or not the Administrative Agent or any Lender
has made any demand for payment and although such obligations, liabilities and
claims may be contingent or unmatured.  The Administrative Agent and each Lender
shall notify such Guarantor promptly of any such set-off and the application
made by the Administrative Agent or such Lender, provided that the failure to
                                                 --------
give such notice shall not affect the validity of such set-off and application.
The rights of the Administrative Agent and each Lender under this Section are in
addition to other rights and remedies (including, without limitation, other
rights of set-off) which the Administrative Agent or such Lender may have.

     5    No Subrogation. Notwithstanding any payment or payments made by any of
          --------------
the Guarantors hereunder or any set-off or application of funds of any of the
Guarantors by any Lender, no Guarantor shall be entitled to be subrogated to any
of the rights of the Administrative Agent or any Lender against the Borrower or
any other Guarantor or any collateral security or guarantee or right of offset
held by any Lender for the payment of the Obligations, nor shall any Guarantor
seek or be entitled to seek any contribution or reimbursement from the Borrower
or any other Guarantor in respect of payments made by such Guarantor hereunder,
until all amounts owing to the Administrative Agent and the Lenders by the
Borrower on account of the Obligations are paid in full and the Commitments are
terminated. If any amount shall be paid to any Guarantor on account of such
subrogation rights at any time when all of the Obligations shall not have been
paid in full, such amount shall be held by such Guarantor in trust for the
Administrative Agent and the Lenders, segregated from other funds of such
Guarantor, and shall, forthwith upon receipt by such Guarantor, be turned over
to the Administrative Agent in the exact form received by such Guarantor (duly
indorsed by such Guarantor to the Administrative
<PAGE>

Agent, if required), to be applied against the Obligations, whether matured or
unmatured, in such order as the Administrative Agent may determine.

     6    Amendments, etc. with respect to the Obligations; Waiver of Rights.
          ------------------------------------------------------------------
Each Guarantor shall remain obligated hereunder notwithstanding that, without
any reservation of rights against any Guarantor and without notice to or further
assent by any Guarantor, any demand for payment of any of the Obligations made
by the Administrative Agent or any Lender may be rescinded by such party and any
of the Obligations continued, and the Obligations, or the liability of any other
party 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 Administrative Agent or any
Lender, and the Credit Agreement, the Notes and the other Loan Documents and any
other documents executed and delivered in connection therewith may be amended,
modified, supplemented or terminated, in whole or in part, as the Administrative
Agent (or the Required Lenders, as the case may be) may deem advisable from time
to time, and any collateral security, guarantee or right of offset at any time
held by the Administrative Agent or any Lender for the payment of the
Obligations may be sold, exchanged, waived, surrendered or released. Neither the
Administrative 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
Obligations or for this Guarantee or any property subject thereto. When making
any demand hereunder against any of the Guarantors, the Administrative Agent or
any Lender may, but shall be under no obligation to, make a similar demand on
the Borrower or any other Guarantor or guarantor, and any failure by the
Administrative Agent or any Lender to make any such demand or to collect any
payments from the Borrower or any such other Guarantor or guarantor or any
release of the Borrower or such other Guarantor or guarantor shall not relieve
any of the Guarantors in respect of which a demand or collection is not made or
any of the Guarantors not so released of their several obligations or
liabilities hereunder, and shall not impair or affect the rights and remedies,
express or implied, or as a matter of law, of the Administrative Agent or any
Lender against any of the Guarantors. For the purposes hereof "demand" shall
include the commencement and continuance of any legal proceedings.

     7    Guarantee Absolute and Unconditional. Each Guarantor waives any and
          ------------------------------------
all notice of the creation, renewal, extension or accrual of any of the
Obligations and notice of or proof of reliance by the Administrative Agent or
any Lender upon this Guarantee or acceptance of this Guarantee, the 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 any of the Guarantors, on
the one hand, and the Administrative 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 any of the Guarantors with respect to the Obligations. Each
Guarantor understands and agrees that this Guarantee shall be construed as a
continuing, absolute and unconditional guarantee of payment without regard to
(a) the validity, regularity or enforceability of the Credit Agreement, any Note
or any other Loan Document, any of the 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 Administrative 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 against the Administrative Agent or any Lender, or (c) any other
circumstance whatsoever (with or without notice to or knowledge of the
<PAGE>

Borrower or such Guarantor) which constitutes, or might be construed to
constitute, an equitable or legal discharge of the Borrower for the 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 Administrative 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
other Person or against any collateral security or guarantee for the Obligations
or any right of offset with respect thereto, and any failure by the
Administrative 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
Administrative 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 each Guarantor and the successors and assigns
thereof, and shall inure to the benefit of the Administrative Agent and the
Lenders, and their respective successors, indorsees, transferees and assigns,
until all the Obligations and the obligations of each 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 Obligations.

     8    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 Obligations is rescinded or must otherwise be restored or returned by
the Administrative Agent or any Lender upon the insolvency, bankruptcy,
dissolution, liquidation or reorganization of the Borrower or any Guarantor, 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 any Guarantor or any
substantial part of its property, or otherwise, all as though such payments had
not been made.

     9    Payments. Each Guarantor hereby guarantees that payments hereunder
          --------
will be paid to the Administrative Agent without set-off or counterclaim in U.S.
Dollars at the office of the Administrative Agent located at 270 Park Avenue,
New York, New York 10017.

     10   Representations and Warranties. Each Guarantor hereby represents and
          ------------------------------
warrants that:

     (a)  it is a corporation duly organized, validly existing and in good

it is currently engaged;

such Guarantor enforceable in accordance with its terms, except as affected by

the enforcement of creditors' rights generally, general equitable principles and
an implied covenant of good faith and fair dealing;

     (d)  the execution, delivery and performance of this Guarantee will not
violate any provision of any Requirement of Law or Contractual Obligation of
such Guarantor and will not result in or require the creation or imposition of
any Lien on any of the properties or revenues of such Guarantor pursuant to any
Requirement of Law or Contractual Obligation of the Guarantor;

     (e)  no consent or authorization of, filing with, or other act by or in
respect of, any arbitrator or Governmental Authority and no consent of any other
Person (including, without limitation, any stockholder or creditor of such
Guarantor) is required in connection with the execution, delivery, performance,
validity or enforceability of this Guarantee;

     (f)  no litigation, investigation or proceeding of or before any arbitrator
or Governmental Authority is pending or, to the knowledge of such Guarantor,

revenues with respect to this Guarantee or any of the transactions contemplated
hereby, which would reasonably be expected to have a material adverse effect on
the business, operations, property or financial or other condition of such
Guarantor.

     11   Authority of Administrative Agent. Each Guarantor acknowledges that
          ---------------------------------

with respect to any action taken by the Administrative Agent or the exercise or
non-exercise by the Administrative Agent of any option, right, request, judgment
or other right or remedy provided for herein or resulting or arising out of this
Guarantee shall, as between the Administrative 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
Administrative Agent and such Guarantor, the Administrative 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 no Guarantor shall be under any
obligation, or entitlement, to make any inquiry respecting such authority.

     12   Notices. All notices, requests and demands to or upon the
          -------
Administrative Agent, any Lender or any Guarantor to be effective shall be in
writing (or by telex, fax or similar electronic transfer confirmed in writing)
and shall be deemed to have been duly given or made when delivered by hand or if
by overnight courier service, when received or if given by mail, when deposited
in the mails by certified mail, return receipt requested, or if by telex, fax or
similar electronic transfer, when sent and receipt has been confirmed, addressed
as follows:

this Section.

     13   Counterparts. This Guarantee may be executed by one or more of the
          ------------
Guarantors on any number of separate counterparts, and all of said counterparts
taken together shall be deemed
<PAGE>

to constitute one and the same instrument. A set of the counterparts of this
Guarantee signed by all the Guarantors shall be lodged with the Administrative
Agent.

     14   Severability. Any provision of this Guarantee 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.

     15   Integration. This Guarantee represents the agreement of each Guarantor
          -----------
with respect to the subject matter hereof and there are no promises or
representations by the Administrative Agent or any Lender relative to the
subject matter hereof not reflected herein.

     16   Amendments in Writing; No Waiver; Cumulative Remedies. (a) None of the
          -----------------------------------------------------
terms or provisions of this Guarantee may be waived, amended, supplemented or
otherwise modified except by a written instrument executed by each Guarantor and
the Administrative Agent, provided that any provision of this Guarantee may be
                          --------
waived by the Administrative Agent and the Lenders in a letter or agreement
executed by the Administrative Agent or by telex or facsimile transmission from
the Administrative Agent.

     (a)  Neither the Administrative Agent nor any Lender shall by any act

breach of any of the terms and conditions hereof. No failure to exercise, nor
any delay in exercising, on the part of the Administrative Agent or any Lender,
any right, power or privilege hereunder shall operate as a waiver thereof. No
single or partial exercise of any right, power or privilege hereunder shall
preclude any other or further exercise thereof or the exercise of any other
right, power or privilege. A waiver by the Administrative Agent or any Lender of
any right or remedy hereunder on any one occasion shall not be construed as a

exercised singly or concurrently and are not exclusive of any other rights or
remedies provided by law.

Agreement"), among the Guarantor, Hanover Compression Inc. (formerly known as

                                                          --------
Lenders and the Administrative Agent.


                              W I T N E S S E T H:
                              -------------------

     WHEREAS, 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, to be evidenced by the Notes issued by the
Borrower under the Credit Agreement;

     WHEREAS, upon the effectiveness of the TIDES Amendment, the Guarantor, a
newly formed subsidiary of the Borrower, will become the parent company of the
Borrower;

     WHEREAS, it is a condition precedent to the obligation of the Lenders to
continue to make their respective Loans to the Borrower under the Credit
Agreement that the Guarantor shall have executed and delivered this Guarantee to
the Administrative Agent for the ratable benefit of the Lenders.

     NOW, THEREFORE, in consideration of the premises and to induce the
Administrative Agent and the Lenders to enter into the Credit Agreement and to
induce the Lenders to make their respective loans to the Borrower under the
Credit Agreement, the Guarantor hereby agrees with the Administrative Agent, for
the ratable benefit of the Lenders, as follows:

     1.   Defined Terms. (a) Unless otherwise defined herein, terms defined
          -------------
in the Credit Agreement and used herein shall have the meanings given to them in
the Credit Agreement.

     (a)  As used herein, "Obligations" means the collective reference to the
                           -----------
unpaid principal of and interest on the Notes and all other obligations and
liabilities of the Borrower to the Administrative Agent or the Lenders
(including, without limitation, interest accruing at the then applicable rate
provided in the Credit Agreement after the maturity of the Loans and interest
accruing at the then applicable rate provided in the Credit Agreement after the
filing of any petition in bankruptcy, or the commencement of any insolvency,
reorganization or like proceeding, relating to the Borrower, whether or not a
claim for post-filing or post-petition interest is allowed in such proceeding),
whether direct or indirect, absolute or contingent, due or to become due, now
existing or hereafter incurred, which may arise under, out of, or in connection
with, the Credit Agreement, the Notes, the Letters of Credit, the other Loan
Documents or any other document made, delivered or given in connection
therewith, whether on
<PAGE>

account of principal, interest, reimbursement obligations, fees, indemnities,
costs, expenses or otherwise (including, without limitation, all fees and
disbursements of counsel to the Administrative Agent or to the Lenders that are
required to be paid by the Borrower or the Guarantor pursuant to the terms of
the Credit Agreement or this Agreement or any other Loan Document).

     (b)  The words "hereof," "herein" and "hereunder" and words of similar
import when used in this Guarantee shall refer to this Guarantee as a whole and
not to any particular provision of this Guarantee, and section and paragraph
references are to this Guarantee unless otherwise specified.

     (c)  The meanings given to terms defined herein shall be equally applicable
to both the singular and plural forms of such terms.

     2.   Guarantee. (a) Subject to the provisions of paragraph 2(b), the
          ---------
Guarantor hereby, unconditionally and irrevocably, guarantees to the
Administrative Agent, for the ratable benefit of the Lenders and their
respective successors, indorsees, transferees and assigns, the prompt and
complete payment and performance by the Borrower when due (whether at the stated
maturity, by acceleration or otherwise) of the Obligations.

     (a)  Anything herein or in any other Loan Document to the contrary
notwithstanding, the maximum liability of the Guarantor hereunder and under the
other Loan Documents shall in no event exceed the amount which can be guaranteed
by the Guarantor under applicable federal and state laws relating to the
insolvency of debtors.

     (b)  The Guarantor further agrees to pay any and all expenses (including,
without limitation, all fees and disbursements of counsel) which may be paid or
incurred by the Administrative Agent or any Lender in enforcing, or obtaining
advice of counsel in respect of, any rights with respect to, or collecting, any
or all of the Obligations and/or enforcing any rights with respect to, or
collecting against, the Guarantor under this Guarantee.  This Guarantee shall
remain in full force and effect until the Obligations are paid in full and the
Commitments are terminated, notwithstanding that from time to time prior thereto
the Borrower may be free from any Obligations.

     (c)  The Guarantor agrees that the Obligations may at any time and from
time to time exceed the amount of the liability of the Guarantor hereunder
without impairing this Guarantee or affecting the rights and remedies of the
Administrative Agent or any Lender hereunder.

     (d)  No payment or payments made by the Borrower, the Guarantor, any other
guarantor or any other Person or received or collected by the Administrative
Agent or any Lender from the Borrower, the Guarantors, any other guarantor or
any other Person by virtue of any action or proceeding or any set-off or
appropriation or application at any time or from time to time in reduction of or
in payment of the Obligations shall be deemed to modify, reduce, release or
otherwise affect the liability of the Guarantor hereunder which shall,
notwithstanding any such payment or payments other than payments made by the
Guarantor in respect of the Obligations or payments received or collected from
the Guarantor in respect of the Obligations, remain liable
<PAGE>

for the Obligations up to the maximum liability of the Guarantor hereunder until
the Obligations are paid in full and the Commitments are terminated.

     3.   Right of Set-off. Upon the occurrence of any Event of Default, the
          ----------------
Guarantor hereby irrevocably authorizes each Lender at any time and from time to
time without notice to such Guarantor, any such notice being expressly waived by
the Guarantor, to set-off and appropriate and apply any and all deposits
(general or special, time or demand, provisional or final), in any currency, and
any other credits, indebtedness or claims, in any currency, in each case whether
direct or indirect, absolute or contingent, matured or unmatured, at any time
held or owing by such Lender to or for the credit or the account of such
Guarantor, or any part thereof in such amounts as such Lender may elect, against
and on account of the obligations and liabilities of such Guarantor to such
Lender hereunder and claims of every nature and description of such Lender
against such Guarantor, in any currency, whether arising hereunder, under the
Credit Agreement, any Note, any Letter of Credit or any Loan Document, as such
Lender may elect, whether or not the Administrative Agent or any Lender has made
any demand for payment and although such obligations, liabilities and claims may
be contingent or unmatured.  The Administrative Agent and each Lender shall
notify such Guarantor promptly of any such set-off and the application made by
the Administrative Agent or such Lender, provided that the failure to give such
                                         --------
notice shall not affect the validity of such set-off and application.  The
rights of the Administrative Agent and each Lender under this Section are in
addition to other rights and remedies (including, without limitation, other
rights of set-off) which the Administrative Agent or such Lender may have.

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

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

Administrative Agent or any Lender, and the Credit Agreement, the Notes and the
other Loan Documents and any other documents executed and delivered in
connection therewith may be amended, modified, supplemented or terminated, in
whole or in part, as the Administrative Agent (or the Required Lenders, as the
case may be) may deem advisable from time to time, and any collateral security,
guarantee or right of offset at any time held by the Administrative Agent or any
Lender for the payment of the Obligations may be sold, exchanged, waived,
surrendered or released. Neither the Administrative 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 Obligations or for this Guarantee or any property
subject thereto. When making any demand hereunder against the Guarantor, the
Administrative Agent or any Lender may, but shall be under no obligation to,
make a similar demand on the Borrower or the Guarantor or guarantor, and any
failure by the Administrative Agent or any Lender to make any such demand or to
collect any payments from the Borrower or any such other guarantor or any
release of the Borrower or such other guarantor shall not relieve the Guarantor
in respect of which a demand or collection is not made or the Guarantor not so
released of its several obligations or liabilities hereunder, and shall not
impair or affect the rights and remedies, express or implied, or as a matter of
law, of the Administrative Agent or any Lender against the Guarantor. For the
purposes hereof "demand" shall include the commencement and continuance of any
legal proceedings.

     6.   Guarantee Absolute and Unconditional. The Guarantor waives any and
          ------------------------------------
all notice of the creation, renewal, extension or accrual of any of the
Obligations and notice of or proof of reliance by the Administrative Agent or
any Lender upon this Guarantee or acceptance of this Guarantee, the 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 the Guarantor, on the one
hand, and the Administrative Agent and the Lenders, on the other hand, likewise
shall be conclusively presumed to have been had or consummated in reliance upon
this Guarantee.  The Guarantor waives diligence, presentment, protest, demand
for payment and notice of default or nonpayment to or upon the Borrower or the
Guarantor with respect to the Obligations.  The Guarantor understands and agrees
that this Guarantee shall be construed as a continuing, absolute and
unconditional guarantee of payment without regard to (a) the validity,
regularity or enforceability of the Credit Agreement, any Note or any other Loan
Document, any of the 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 Administrative 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 against the Administrative
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 Obligations, or of such Guarantor under this Guarantee, in
bankruptcy or in any other instance.  When pursuing its rights and remedies
hereunder against the Guarantor, the Administrative 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 other Person or against any collateral security
or guarantee for the Obligations or any right of offset with respect thereto,
and any failure by the Administrative 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
<PAGE>

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 Administrative 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 the Guarantor
and its successors and assigns, and shall inure to the benefit of the
Administrative Agent and the Lenders, and their respective successors,
indorsees, transferees and assigns, until all the Obligations and the
obligations of the 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 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 Obligations is rescinded or must otherwise be restored or returned by
the Administrative Agent or any Lender upon the insolvency, bankruptcy,
dissolution, liquidation or reorganization of the Borrower or the Guarantor, 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 Guarantor or any
substantial part of its property, or otherwise, all as though such payments had
not been made.

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

generally, general equitable principles and an implied covenant of good faith
and fair dealing;

     (d)  the execution, delivery and performance of this Guarantee will not
violate any provision of any Requirement of Law or Contractual Obligation of

Requirement of Law or Contractual Obligation of the Guarantor;

     (e)  no consent or authorization of, filing with, or other act by or in
respect of, any arbitrator or Governmental Authority and no consent of any other

connection with the execution, delivery, performance, validity or enforceability
of this Guarantee;

     (f)  no litigation, investigation or proceeding of or before any arbitrator
or Governmental Authority is pending or, to the knowledge of such Guarantor,

non-exercise by the Administrative Agent of any option, right, request, judgment
or other right or remedy provided for herein or resulting or arising out of this
Guarantee shall, as between the Administrative 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
Administrative Agent and such Guarantor, the Administrative 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 Guarantor shall not be under
any obligation, or entitlement, to make any inquiry respecting such authority.

     11.  Notices. All notices, requests and demands to or upon the
          -------
Administrative Agent, any Lender or the Guarantor to be effective shall be in
writing (or by telex, fax or similar electronic transfer confirmed in writing)
and shall be deemed to have been duly given or made when delivered by hand or if

          ------------
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.

or otherwise modified except by a written instrument executed by the Guarantor

breach of any of the terms and conditions hereof. No failure to exercise, nor

exercised singly or concurrently and are not exclusive of any other rights or
remedies provided by law.
