binding obligations of such Obligor enforceable in accordance with the
respective terms thereof and of this Agreement, except, in each case, (a) as
such enforceability may be limited by bankruptcy, insolvency, reorganization,
moratorium, fraudulent transfer or other similar laws relating to or affecting
the enforcement of creditors' rights generally, and by general principles of
equity which may limit the right to obtain equitable remedies (regardless of
whether such enforceability is a proceeding in equity or at law) and (b) as to
the enforceability of provisions for indemnification for violation of applicable
securities laws, limitations thereon arising as a matter of law or public
policy.

                  SECTION 6.03. Governmental Consents, Etc. No authorization,
consent, approval, license or exemption of or filing or registration with any
Governmental Authority, is

<PAGE>

necessary for the valid execution, delivery or performance by any Obligor of any
Loan Document to which it is a party, except those that have been obtained and
such matters relating to performance as would ordinarily be done in the ordinary
course of business after the Execution Date.

                  SECTION 6.04. Conflicting or Adverse Agreements or
Restrictions. Neither the execution, delivery and performance by any Obligor of
the Loan Documents to which it is a party, nor compliance with the terms and
provisions thereof, nor the extensions of credit contemplated by the Loan
Documents, (a) will breach or violate any applicable Requirement of Law, (b)
will result in any breach or violation of, any of the terms, covenants,
conditions or provisions of, or constitute a default under, or result in the
creation or imposition of (or the obligation to create or impose) any Lien upon
any of its property or assets pursuant to the terms of any indenture, mortgage,
deed of trust, agreement or other instrument to which it or any of its
consolidated Subsidiaries is party or by which any property or asset of it or
any of its consolidated Subsidiaries is bound or to which it is subject, except
for breaches, violations and defaults under clauses (a) and (b) that
collectively for all Obligors will not have a Material Adverse Effect or (c)
will violate any provision of the organizational documents of any Obligor.

                  SECTION 6.05. Title to Assets. Each Obligor and each
consolidated Subsidiary of the Bermuda Parent has good and indefeasible title to
its assets, except for such defects in title as would not in the aggregate have
a Material Adverse Effect. As of the Effective Date, the property of the
Obligors and their Subsidiaries is subject to no Liens, except Permitted Liens.

                  SECTION 6.06. Litigation. Except for actions, suits or
proceedings described in the filings made by the U.S. Borrower or the Bermuda
Parent with the Securities and Exchange Commission pursuant to the Exchange Act,
as of the Effective Date there are no actions, suits or proceedings pending for
which service of process has been accomplished or, to the best knowledge of any
Obligor, threatened with respect to any Obligor, the Loan Documents or any
transactions contemplated therein that are reasonably likely to have
(individually or collectively) a Material Adverse Effect.

                  SECTION 6.07. Information; Financial Statements. All
information heretofore furnished by the U.S. Borrower and the Bermuda Parent to
the Administrative Agent or any Lender in connection with this Agreement, as
affected by the disclosures made herein, in the other Loan Documents and in the
filings made by the U.S. Borrower and the Bermuda Parent with the Securities and
Exchange Commission pursuant to the Exchange Act, did not as of the date thereof
and will not as of the date of the initial Credit Event hereunder, when read
together and taken as a whole, 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 any material respect. As of any date prior
to the Merger Date, there has been no material adverse change since December 31,
2000 in the financial condition, business or operations of the U.S. Borrower and
its Subsidiaries taken as a whole which could reasonably be expected to have a
Material Adverse Effect. As of the Merger Date or any date thereafter, there has
been no material adverse change since the Merger Date in the financial
condition, business or operations of the Bermuda Parent and its Subsidiaries
taken as a whole which could reasonably be expected to have a Material Adverse
Effect.

                  SECTION 6.08. Investment Company Act. Neither the Bermuda
Parent nor any of its Subsidiaries is, or is regulated as an "investment
company," as such term is defined in the Investment Company Act of 1940, as
amended.

                  SECTION 6.09. Public Utility Holding Company Act. Neither the
Bermuda Parent nor any of its Subsidiaries is a non-exempt "holding company," or
subject to regulation as such, or, to the knowledge of any Obligor's officers,
an "affiliate" 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.

                  SECTION 6.10. ERISA. (a) The U.S. Borrower, and each ERISA
Affiliate has maintained and administered each Plan in compliance with all
applicable laws except for such instances of noncompliance as have not resulted
in and would not reasonably be expected to have a Material Adverse Effect.
Neither the U.S. Borrower nor any ERISA Affiliate has incurred any liability
pursuant to Title I or IV of ERISA or the penalty or excise tax provisions of
the Code relating to employee benefit plans (as defined in Section 3 of ERISA),
and no event, transaction or condition has occurred or exists that would
reasonably be expected to result in the incurrence of any such liability by the
U.S. Borrower or any ERISA Affiliate, or in the imposition of any Lien on any of
the rights, properties or assets of the U.S. Borrower or any ERISA Affiliate
pursuant to Title I or IV of ERISA Sections 401(a)(29) or 412 of the Code, other
than such liabilities or Liens as would in the aggregate reasonably be expected
to have a Material Adverse Effect.

                  (b) No accumulated funding deficiency (as defined in Section
412 of the Code or Section 302 of ERISA), in excess of $25,000,000, whether or
not waived, exists or is expected to be incurred with respect to any Plan.

                  (c) The U.S. Borrower and its ERISA Affiliates have not
incurred withdrawal liabilities (and are not subject to contingent withdrawal
liabilities) under section 4201 or 4204 of ERISA in respect of Multiemployer
Plans that in the aggregate would reasonably be expected to have a Material
Adverse Effect.

                  (d) All contributions have been timely made to all employee
benefit plans, as defined in Section 3 of ERISA, except for such failures as
would not reasonably be expected to have a Material Adverse Effect.

                  SECTION 6.11. Tax Returns and Payments. Each Obligor and each
Material Subsidiary has caused to be filed all federal income tax returns and
other material tax returns, statements and reports (or obtained extensions with
respect thereto) which are required to be filed and have paid or deposited or
made adequate provision in accordance with GAAP for the payment of all taxes
(including estimated taxes shown on such returns, statements and reports) which
are shown to be due pursuant to such returns, except where the failure to pay
such taxes (collectively for the Obligors and the Material Subsidiaries, taken
as a whole) would not have a Material Adverse Effect. No material income tax
liability of any Obligor or any Material Subsidiary has been asserted by the
Internal Revenue Service of the United States or any other

                                      -3-
<PAGE>

Governmental Authority for any taxes in excess of those already paid, except for
taxes which are being contested in good faith by appropriate proceedings and for
which adequate reserves in accordance with GAAP have been created on the books
of the Obligors and their Subsidiaries.

                  SECTION 6.12. Requirements of Law; Environmental Matters. (a)
The Obligors and each of their consolidated Subsidiaries are in compliance with
all Requirements of Law, applicable statutes, regulations and orders of, and all
applicable restrictions imposed by, all Governmental Authorities in respect of
the conduct of its business and the ownership of their property, except for such
noncompliances which, in the aggregate, would not have a Material Adverse
Effect.

                  (b) The U.S. Borrower monitors, in the ordinary course of its
business, the effect of existing Environmental Laws, and each claim asserted
against it, any other Obligor, or any of their Subsidiaries by any Governmental
Authority alleging potential liability or responsibility for violation of any
Environmental Law, on its business operations and properties. As a result
thereof, the U.S. Borrower has reasonably concluded that such Environmental Laws
and any such claims would not, in the aggregate, have a Material Adverse Effect.

                  SECTION 6.13. Purpose of Loans. (a) All proceeds of the Loans
will be used by a Borrower for the purposes set forth in Section 2.06.

                  (b) None of the proceeds of the Loans under this Agreement
were or will be used directly or indirectly for the purpose of buying or
carrying any "margin stock" within the meaning of Regulation U (herein called
"margin stock") or for the purpose of reducing or retiring any indebtedness
which was originally incurred to buy or carry a margin stock, or for any other
purpose which might constitute this transaction a "purpose" credit within the
meaning of Regulation U. Neither any Obligor nor any agent acting on its behalf
has taken or will take any action which might cause this Agreement or any other
Loan Document to violate Regulation T, U or X, or any other regulation of the
Board or to violate the Exchange Act. Margin stock did not on the Execution
Date, and does not now, constitute more than 25% of the assets of the U.S.
Borrower or any other Obligor.

                  SECTION 6.14. Designation of this Agreement and the
Obligations. The Obligations under this Agreement and under the other Loan
Documents constitute "Designated Senior Indebtedness" (as such phrase is used in
the October 1997 Debenture Indenture) and are pari passu to Indebtedness under
the May 1996 Debenture Indenture.

                  SECTION 6.15. No Default. No Default or Event of Default has
occurred and is continuing.

         Default or an Event of Default; or

                           (iii) the occurrence of a Change of Control or Change
         of Control Event;

the provisions of Article VIII as at the end of such fiscal quarter or fiscal
year, as the case may be and (ii) in Section 7.01(b), to the extent there has
been any change in the information previously furnished to the Administrative
Agent and the Lenders on Schedule 6.01, a revised Schedule 6.01.

                  (f) Promptly, and in any event within 30 days after any
Responsible Officer of any Obligor obtains knowledge thereof, notice:

                           (i) of the occurrence or expected occurrence of any
         material Reportable Event with respect to any Plan, a failure to make
         any material required contribution to a Plan, any Lien in favor of the
         PBGC or a Plan, or any withdrawal from, or the termination,
         reorganization or insolvency (within the meaning of such terms as used

         meaning of such terms as used in ERISA) of, any Plan which termination,
         reorganization or insolvency would reasonably be expected to have a
         Material Adverse Effect, except that no notice shall be required with
         respect to the merger of a defined contribution plan of one ERISA
         Affiliate into a defined contribution plan of another ERISA Affiliate.

                  (g) From time to time and with reasonable promptness, such
other information or documents (financial or otherwise) with respect to the

Subsidiaries to, permit, or cause to be permitted, any Lender, upon written
notice, to visit and inspect any of the properties of each of the Bermuda Parent
and the U.S. Borrower and their Subsidiaries, to examine the corporate books and
financial records of each of the Bermuda Parent and the U.S. Borrower and their
Subsidiaries and to discuss the affairs, finances and accounts of any such
corporations with a Responsible Officer of each of the Bermuda Parent and the
U.S. Borrower and such Subsidiaries, all at such reasonable times and as often
as such Lender(s), through the Administrative Agent, may reasonably request.

Borrower to, pay or discharge or cause to be paid or discharged, before the same

or imposed upon such Obligor or such Material Subsidiary or Subsidiary Borrower,
as applicable, or upon the income, profits or property of such Obligor or such
Material Subsidiary or Subsidiary Borrower, as applicable, except for (i) such
taxes, assessments as would not, individually or in the aggregate, have a
Material Adverse Effect and (ii) any such tax, assessment or governmental charge

appropriate proceedings and for which adequate reserves have been established in
accordance with GAAP.

                  SECTION 7.05. Existence. Except as expressly permitted

                  SECTION 7.06. ERISA Information and Compliance. Except with
respect to matters described in clauses (a), (c) and (d) below which would not

promptly furnish to Administrative Agent: (a) immediately upon receipt, a copy
of any notice of complete or partial withdrawal liability under ERISA and any
notice from the PBGC under ERISA of an intent to terminate or appoint a trustee
to administer any Plan, (b) if requested by the Administrative Agent, promptly
after the filing thereof with the United States Secretary of Labor or the PBGC
or the Internal Revenue Service, copies of each annual and other report with
respect to each Plan or any trust created thereunder, (c) immediately upon
becoming aware of the occurrence of any Reportable Event, or of any "prohibited
transaction", as such term is defined in Section 4975 of the Code, in connection
with any Plan or any trust created thereunder, a written notice signed by a
Responsible Officer of the applicable Borrower or the applicable ERISA Affiliate
specifying the nature thereof, what action the applicable Borrower or the
applicable ERISA Affiliate is taking or proposes to take with respect thereto,
and, when known, any action taken by the PBGC, the Internal Revenue Service, the
Department of Labor or any other applicable Governmental Authority with respect
thereto, (d) promptly after the filing or receiving thereof by any Borrower or

required by ERISA or Section 412 of the Code promptly after the request is
submitted by Borrower or any ERISA Affiliate to the Secretary of the Treasury,
the Department of Labor, the Internal Revenue Service or any other applicable
Governmental Authority. The U.S. Borrower covenants that it shall and shall
cause each ERISA Affiliate to comply, with respect to each Plan and
Multiemployer Plan, with all applicable provisions of ERISA and the Code, except
to the extent that any failure to comply would not reasonably be expected to
have a Material Adverse Effect.

                  SECTION 7.07. Capital Adequacy. If any Lender determines in
good faith that compliance with any law or regulation or any guideline or
request from any central bank or other Governmental Authority (whether or not
having the force of law) implemented or effective after

                                      -3-
<PAGE>

the Effective Date affects or would affect the amount of capital required or
expected to be maintained by such Lender or any corporation controlling such
Lender and that the amount of such capital is increased by or based upon the
existence of such Lender's commitment to lend or other commitments of this type,
then, upon demand by such Lender (with a copy of any such demand to the
Administrative Agent), the U.S. Borrower shall immediately pay to Administrative
Agent for the account of such Lender, from time to time as specified by such
Lender, additional amounts (without duplication of any other amounts payable in
respect of increased costs) sufficient to compensate such Lender, in light of
such circumstances, with respect to such Lender, to the extent that such Lender
reasonably determines such increase in capital to be allocable to the existence
of such Lender's commitment to lend under this Agreement. A certificate as to
such amount and detailing the calculation of such costs shall be submitted to
the U.S. Borrower by such Lender, such certificate to be presumed correct for
all purposes, absent manifest error.

                  SECTION 7.08. Subsidiaries. The Bermuda Parent covenants that
the Subsidiaries identified on Schedule 6.01 are the only Material Subsidiaries
as of the Execution Date. Should any Subsidiary, subsequent to the date hereof,
become a Material Subsidiary, the Bermuda Parent shall deliver to the
Administrative Agent and the Lenders a revised Schedule 6.01 as provided in
Section 7.01(e).

                                  ARTICLE VIII
                               NEGATIVE COVENANTS

                  Each of the Bermuda Parent and the U.S. Borrower covenants and

liquidate or dissolve its affairs, or effect any merger or consolidation, and
the Bermuda Parent will not, and will not permit any consolidated Subsidiary to,
sell, lease or otherwise dispose of all or substantially all of its property or
assets (other than sales of inventory in the ordinary course of business) except
that this Section 8.02 shall not prohibit any of the following transactions, or
any agreement to effect the same:

                  (a) if, at the time thereof and immediately after giving
effect thereto, no Event of Default or Default shall have occurred and be
continuing, the merger of any other Person with and into the Bermuda Parent or
any of its Subsidiaries, if (i) in any transaction involving the Bermuda Parent
or the U.S. Borrower, the Bermuda Parent or the U.S. Borrower, as applicable, is
the surviving Person, (ii) in any other transaction, a Wholly-Owned Subsidiary
is the surviving entity, and (iii) in either case, the Bermuda Parent, the U.S.
Borrower, and their Subsidiaries shall be in compliance, on a pro forma basis
after giving effect to such transaction, with the covenants contained in this
Article VIII recomputed as of the last day of the most recently ended fiscal
quarter of the Bermuda Parent, the U.S. Borrower, and their Subsidiaries as if
such transaction had occurred on the first day of each relevant period for
testing such compliance, and the U.S. Borrower (with respect to any merger with
a Person not a consolidated Subsidiary of the Bermuda Parent) shall have
delivered to the Administrative Agent an officer's certificate to such effect,
together with all relevant financial information and calculations demonstrating
such compliance;

                  (b) transactions and transfers of assets among or between
Obligors and/or Wholly-Owned Subsidiaries or among and between Wholly-Owned

compliance, on a pro forma basis after giving effect to such transactions, with
the covenants contained in this Article VIII recomputed as of the last day of
the most recently ended fiscal quarter of each of the Bermuda Parent, the U.S.
Borrower, and their Subsidiaries as if the transaction in question had occurred

their consolidated Subsidiaries to, directly or indirectly, conduct any business

Weatherford Saudi Arabia Limited, or Universal Compression Holdings, Inc., on
terms that are less favorable to the Bermuda Parent or such consolidated
Subsidiary, as the case may be, than would be available in a comparable arm's

regular fees to directors of the Bermuda Parent or the U.S. Borrower who are not
employees of the Bermuda Parent or the U.S. Borrower; (ii) loans and advances to

Subsidiaries; (iii) any other transaction with any employee, officer or director
of the Bermuda Parent, the U.S. Borrower or any of their respective Subsidiaries

ordinary course of business and approved by, as applicable, the Board of
Directors of the Bermuda Parent, the Board of Directors of the U.S. Borrower, or
the Board of Directors of such Subsidiary permitted by this Agreement; and (iv)
customary underwriting or similar transactions with an investment banking
Affiliate.

                SECTION 8.08. Restrictions on Subsidiary Dividends. Each of the
Bermuda Parent and the U.S. Borrower will not and will not permit any of its
consolidated Subsidiaries to enter into any agreement or contract which limits
or restricts in any way the payment of any dividends or distributions by any
consolidated Subsidiary of any Obligor to such Obligor or to another
consolidated Subsidiary of such Obligor.

                SECTION 8.09. Debentures. Except as expressly permitted in
writing by the Majority Lenders, no Obligor will amend, modify or obtain or
grant a waiver of any provision of the October 1997 Debentures, the October 1997
Debenture Indenture, the May 1996 Debentures, or the May 1996 Debenture
Indenture if such amendment, modification or waiver would be adverse to the
Lenders.

                  SECTION 8.10. The Debenture Indentures. No Obligor will take
any action that could result in the Obligations' failing to be classified as (a)
"Designated Senior Indebtedness" (as such phrase is used in the October 1997
Debenture Indenture) or (b) pari passu to Indebtedness under the May 1996
Debenture Indenture.

         (i) without notice to any Borrower or any other Person, declare the

       immediately due and payable, without notice (including notice of
       acceleration and notice of intent to accelerate), presentment, demand,
       protest or other formalities of any kind, all of which are hereby

         (iii) exercise any or all other rights and remedies available to the
       Administrative Agent or any Lenders under the Loan Documents, at law or

the continuance of any Event of Default, each Lender is hereby authorized at any
time and from time to time, without notice to any Obligor (any such notice being
expressly waived by each Obligor),

                                      -3-
<PAGE>

to setoff and apply any and all deposits (general or special, time or demand,
provisional or final but excluding the funds held in accounts clearly designated
as escrow or trust accounts held by any Obligor for the benefit of Persons which
are not Affiliates of any Obligor), whether or not such setoff results in any
loss of interest or other penalty, and including without limitation all
certificates of deposit, at any time held, and any other funds or property at
any time held, and other indebtedness at any time owing by such Lender to or for
the credit or the account of any Obligor against any and all of the Obligations
irrespective of whether or not such Lender or the Administrative Agent will have
made any demand under this Agreement, the Notes or any other Loan Document.
Should the right of any Lender to realize funds in any manner set forth above be
challenged and any application of such funds be reversed, whether by court order
or otherwise, the Lenders shall make restitution or refund to the applicable
Obligor, as the case may be, pro rata in accordance with their Commitments. Each
Lender agrees to promptly notify the each Borrower and the Administrative Agent
after any such setoff and application, provided that the failure to give such
notice will not affect the validity of such setoff and application. The rights
of the Administrative Agent and the Lenders under this Section are in addition
to other rights and remedies (including without limitation other rights of
setoff) which the Administrative Agent or the Lenders may have. This Section is
subject to the terms and provisions of Section 4.05 and Section 12.18.

                  SECTION 9.03. Preservation of Security for Unmatured
Obligations. In the event that, following (a) the occurrence of an Event of
Default and the exercise of any rights available to the Administrative Agent or
any Lender under the Loan Documents, and (b) payment in full of the principal
amount then outstanding of and the accrued interest on the Loans and fees and
all other amounts payable hereunder and under the Loan Documents shall remain
outstanding and undrawn upon, the Administrative Agent shall be entitled to hold
(and each Borrower and each other Obligor hereby grants and conveys to the
Administrative Agent a security interest in and to) all cash or other proceeds
realized or arising out of the exercise of any rights available under the Loan
Documents, at law or in equity. Such proceeds shall be held for the ratable
benefit of the Lenders. The rights, titles, benefits, privileges, duties and
obligations of the Administrative Agent with respect thereto shall be governed
by the terms and provisions of this Agreement. The Administrative Agent may, but
shall have no obligation to, invest any such proceeds in such manner as the
Administrative Agent, in the exercise of its sole discretion, deems appropriate.
Nothing in this Section shall cause or permit an increase in the maximum amount
of the Obligations permitted to be outstanding from time to time under this
Agreement.

                  SECTION 9.04. Other Remedies. No remedy conferred herein or in
any of the other Loan Documents is to be exclusive of any other remedy, and each
and every remedy contained herein or in any other Loan Document shall be
cumulative and shall be in addition to every other remedy given hereunder and
under the other Loan Documents now or hereafter existing at law or in equity or
by statute or otherwise.

                  SECTION 9.05. Currency Conversion After Maturity. At any time
following the occurrence of an Event of Default and the acceleration of the
maturity of the Obligations owed to the Lenders hereunder, the Lenders shall be
entitled to convert, with two (2) Business Days' prior notice to the applicable
Borrower, any and all or any part of the then unpaid and outstanding Loans
denominated in a currency other than Dollars into Loans denominated in

                                      -4-
<PAGE>

Dollars. Any such conversion shall be calculated so that the principal amount of
the resulting Loans shall be the Dollar Equivalent of the principal amount of
the Loan being converted on the date of conversion. Any accrued and unpaid
interest denominated in such currency other than Dollars at the time of any such
conversion shall be similarly converted to Dollars, and such converted Loans and
accrued and unpaid interest thereon shall thereafter bear interest in accordance
with the terms hereof.

                  SECTION 9.06. Application of Moneys During Continuation of
Event of Default. (a) So long as an Event of Default of which the Administrative
Agent shall have given notice to the Lenders shall continue, all moneys received
by the Administrative Agent (i) from any Obligor under the Loan Documents shall,
except as otherwise required by law, be distributed by the Administrative Agent
on the dates selected by the Administrative Agent as follows:

                first, to payment of the unreimbursed expenses for which the
                Administrative Agent or any Lender is to be reimbursed pursuant
                to Section 13.03 and to any unpaid fees owing to the
                Administrative Agent;

                second, to the ratable payment of accrued but unpaid interest on
                the Obligations;

                third, to the ratable payment of unpaid principal of the
                Obligations;

                fourth, to the ratable payment of all other amounts payable by
                the Obligors hereunder;

                fifth, to the ratable payment of all other Obligations, until
                all Obligations shall have been paid in full; and

                finally, to payment to the Obligors, or their respective
                successors or assigns, or as a court of competent jurisdiction
                may direct, of any surplus then remaining from such proceeds.

                  (b) The term "unpaid" as used in this Section 9.06 shall mean
all Obligations outstanding as of any such distribution date as to which prior
distributions have not been made, after giving effect to any adjustments which
are made pursuant to Section 9.02 of which the Administrative Agent shall have
been notified.

                                    GUARANTY

                  SECTION 11.01 Guaranty. (a) In consideration of, and in order
to induce the Lenders to make Loans to the Subsidiary Borrowers and the U.S.
Borrower, the Guarantors hereby absolutely, unconditionally and irrevocably
guarantee in favor of all of the Lenders, the punctual payment and performance
when due, whether at stated maturity, by acceleration or otherwise, of the
Borrower Obligations and all covenants of the Borrowers, now or hereafter
existing under this Agreement and the other Loan Documents to which any Borrower
is a party, whether for principal, interest (including interest accruing or
becoming owing both prior to and subsequent to the commencement of any
proceeding against or with respect to such Borrower under any applicable
Bankruptcy Code, fees, commissions, expenses (including reasonable attorneys'
fees and expenses)), indemnities, or otherwise (all such obligations being, as
applicable, the "Guaranteed Obligations"). Each of the Guarantors agrees to pay
any and all expenses incurred by each Lender and the Administrative Agent in
enforcing this Guaranty against any of the Guarantors.

                  (b) This Guaranty is an absolute, unconditional, present and
continuing guaranty of payment and not of collection and is in no way
conditioned upon any attempt to collect from any Obligor or any other action,
occurrence or circumstance whatsoever.

                  SECTION 11.02. Continuing Guaranty. (a) Each Guarantor
guarantees that the Guaranteed Obligations will be paid strictly in accordance
with the terms of this Agreement and the other Loan Documents. Each Guarantor
agrees that, to the maximum extent permitted by applicable law, the Guaranteed
Obligations and Loan Documents to which any Borrower is a party may be extended
or renewed, and indebtedness thereunder repaid and reborrowed in whole or in
part, without notice to or assent by any of the Guarantors, and that each
Guarantor will remain bound upon this Guaranty notwithstanding any extension,
renewal or other alteration of any of the Guaranteed Obligations or such Loan
Documents or any repayment and reborrowing of Loans to any Borrower. The
obligations of each Guarantor under this Guaranty are joint and several and
absolute and unconditional irrespective of the value, genuineness, validity,
regularity or enforceability of the obligations of the other Guarantors under
this Agreement or any other Loan Document or any substitution, release or
exchange of any other guarantee of or security for the Obligations. To the
maximum extent permitted by applicable law, except as otherwise expressly
provided in this Agreement or any other Loan Document to which any Guarantor is
a party, the obligations of each Guarantor under this Guaranty shall be
absolute, unconditional and irrevocable, and shall be performed strictly in
accordance with the terms hereof under any circumstances whatsoever, including:

         (i) any modification, amendment, supplement, renewal, extension for any
       period, increase, decrease, alteration or rearrangement of all or any
       part of the Guaranteed Obligations, or of this Agreement or any other
       Loan Document executed in connection herewith, or any contract or
       understanding among the Bermuda Parent, U.S. Holdings, U.S. Borrower, the
       U.K. Borrower, the Dutch Borrower, any other Subsidiary Borrower, any

       be granted or given by the Lenders to any Guarantor, any Obligor or any
       other Person liable on the Guaranteed Obligations;

         (iii) the insolvency, bankruptcy, arrangement, adjustment, composition,
       liquidation, disability, dissolution or lack of power of any Guarantor,

       Subsidiary Borrower, or any other Person at any time liable for the
       payment of all or part of the Guaranteed Obligations; or any dissolution
       of any Guarantor or any Borrower, or any sale, lease or transfer of any
       or all of the assets of any Guarantor or any Borrower, or any changes in
       the shareholders of any Guarantor or any Borrower, or any reorganization
       of any Guarantor or any Borrower;

         (iv) the invalidity, illegality or unenforceability of all or any part
       of the Guaranteed Obligations, or any document or agreement executed in
       connection with the Guaranteed Obligations, for any reason whatsoever,
       including the fact that (A) the Guaranteed Obligations, or any part
       thereof, exceed the amount permitted by law, (B) the act of creating the
       Guaranteed Obligations, or any part thereof is ultra vires, (C) the
       officers or representatives executing the documents or otherwise creating
       the Guaranteed Obligations acted in excess of their authority, (D) the
       Guaranteed Obligations or any part thereof violate applicable usury laws,
       (E) any Guarantor or any Borrower has valid defenses, claims, and offsets
       (whether at law or in equity, by agreement or by statute) which render
       the Guaranteed Obligations wholly or partially uncollectible from any
       Guarantor or any Borrower, (F) the creation, performance, or repayment of
       the Guaranteed Obligations (or execution, delivery and performance of any
       document or instrument representing any part of the Guaranteed
       Obligations or executed in connection with any of the Guaranteed
       Obligations, or given to secure the repayment of the Guaranteed
       Obligations) is illegal, uncollectible, legally impossible or
       unenforceable, or (G) this Agreement, any other Loan Document, or any
       other document or instrument pertaining to any of the Guaranteed
       Obligations has been forged or otherwise is irregular or not genuine or
       authentic;

       or assure the payment of the Guaranteed Obligations or any part thereof;
       it being recognized, acknowledged, and agreed by each Guarantor that such
       Guarantor may be required to pay the Guaranteed Obligations in full
       without assistance or support of any other Person, and that such
       Guarantor has not been induced to enter into this Guaranty on the basis
       of a contemplation, belief, understanding or agreement that any other
       Person will be liable to perform the Guaranteed Obligations or that the
       Administrative Agent or any Lender will look to any other Person to
       perform the Guaranteed Obligations;

         (vi) the taking or accepting of any other security, collateral or
       guaranty, or other assurance of payment, for all or any part of the
       Guaranteed Obligations;

                                      -2-

         (vii) any release, surrender, exchange, subordination, deterioration,
       waste, loss or impairment of any collateral, property or security, at any
       time existing in connection with, or assuring or securing payment of, all
       or any part of the Guaranteed Obligations;

         (viii) the failure of the Administrative Agent, the Lenders or any
       other Person to exercise diligence or reasonable care in the
       preservation, protection, enforcement, sale or other handling or

         (ix) the fact that any collateral, security or Lien contemplated or
       intended to be given, created or granted as security for the repayment of
       the Guaranteed Obligations shall not be properly perfected or created, or
       shall prove to be unenforceable or subordinate to any other Lien; it
       being recognized and agreed by each Guarantor that such Guarantor is not
       entering into this Guaranty in reliance on, or in contemplation of the

         (xi) any other action taken or omitted to be taken with respect to this
       Agreement, any other Loan Document, the Guaranteed Obligations, or the

       prejudices Guarantors or increases the likelihood that the Guarantors
       will be required to pay the Guaranteed Obligations pursuant to the terms
       hereof;

it being the unambiguous and unequivocal intention of each Guarantor that such
Guarantor shall be obligated to pay the Guaranteed Obligations when due,
notwithstanding any occurrence, circumstance, event, action, or omission
whatsoever, whether contemplated or uncontemplated, and whether or not otherwise
or particularly described herein, except for the full and final payment and
satisfaction of the Guaranteed Obligations after the termination of all of the
Commitments.

                  (b) Each Guarantor further agrees that, to the fullest extent
permitted by law, as between any of the Guarantors, on the one hand, and the
Lenders and the Administrative Agent, on the other hand, (i) the maturity of any
of the Guaranteed Obligations may be accelerated as provided in Article IX for
the purposes of this Guaranty, notwithstanding any stay, injunction, or other
prohibition preventing such acceleration of the Guaranteed Obligations, and (ii)
in the event of any acceleration of any Guaranteed Obligations as provided in
Article IX, such Guaranteed Obligations (whether or not due and payable) shall
forthwith become due and payable by the Guarantors for the purpose of this
Guaranty.

of any payment of, or proceeds of any security applied (or intended to be
applied) to the payment of all or any

<PAGE>

part of the Guaranteed Obligations, the Administrative Agent or any Lender is
for any reason compelled to surrender or voluntarily surrenders, such payment or
proceeds to any Person (a) because such payment or application of proceeds is or
may be avoided, invalidated, declared fraudulent, set aside, determined to be
void or voidable as a preference, fraudulent conveyance, fraudulent transfer,
impermissible set-off or a diversion of trust funds or (b) for any other reason,
including (i) any judgment, decree or order of any court or administrative body
having jurisdiction over the Administrative Agent, any Lender or any of their
respective properties or (ii) any settlement or compromise of any such claim
effected by the Administrative Agent or any Lender with any such claimant
(including any of the Borrowers), then the Guaranteed Obligations or any part
thereof intended to be satisfied shall be reinstated and continue, and this
Guaranty shall continue in full force as if such payment or proceeds have not
been received, notwithstanding any revocation thereof or the cancellation of any
instrument evidencing any of the Guaranteed Obligations or otherwise; and each
Guarantor shall be liable to pay the Administrative Agent and the Lenders, and
hereby do indemnify the Administrative Agent and the Lenders and hold them
harmless for the amount of such payment or proceeds so surrendered and all
reasonable expenses (including reasonable attorneys' fees, court costs and
expenses attributable thereto) incurred by the Administrative Agent or any such
Lender in the defense of any claim made against it that any payment or proceeds
received by the Administrative Agent or any such Lender in respect of all or
part of the Guaranteed Obligations must be surrendered. The provisions of this
paragraph shall survive the termination of this Guaranty and any satisfaction
and discharge of any Borrower by virtue of any payment, court order, or any law.

                  SECTION 11.04. Waiver. Each Guarantor hereby waives
promptness, diligence, notice of acceptance and any other notice with respect to
any of the Guaranteed Obligations and this Guaranty and waives presentment,
demand for payment, notice of intent to accelerate, notice of dishonor or
nonpayment and any requirement that the Administrative Agent or any Lender
institute suit, collection proceedings or take any other action to collect any
of the Guaranteed Obligations, including any requirement that the Administrative
Agent or any Lender protect, secure, perfect or insure any Lien against any
property subject thereto or exhaust any right or take any action against any
Borrower or any other Person or any collateral (it being the intention of the
Administrative Agent, the Lenders, and the Guarantors that this Guaranty is to
be a guaranty of payment and not of collection). It shall not be necessary for
the Administrative Agent or any Lender, in order to enforce any payment by any
Guarantor hereunder, to institute suit or exhaust its rights and remedies
against any other Guarantor, the U.S. Borrower, the U.K. Borrower, the Dutch
Borrower, any other Subsidiary Borrower, or any other Person, including others
liable to pay the Guaranteed Obligations, or to enforce its rights against any
security ever given to secure payment thereof. Each Guarantor hereby expressly
waives to the maximum extent permitted by applicable law each and every right to
which it may be entitled by virtue of the suretyship laws of the State of Texas
or any other state in which it may be located, including any and all rights it
may have pursuant to Rule 31, Texas Rules of Civil Procedure, Section 17.001 of
the Texas Civil Practice and Remedies Code and Chapter 34 of the Texas Business
and Commerce Code. Each Guarantor hereby waives marshaling of assets and
liabilities, notice by the Administrative Agent or any Lender of any
indebtedness or liability to which such Lender applies or may apply any amounts
received by such Lender, and of the creation, advancement, increase, existence,
extension, renewal, rearrangement or modification of the Guaranteed Obligations.
Each Guarantor expressly waives, to the extent permitted by applicable law, the

                                      -4-

benefit of any and all laws providing for exemption of property from execution
or for valuation and appraisal upon foreclosure.

                  SECTION 11.05. Full Force and Effect. This Guaranty is a
continuing guaranty and shall remain in full force and effect until all of the
Guaranteed Obligations under this Agreement and the other Loan Documents to
which any Borrower is a party and all other amounts payable under this Guaranty
have been paid in full (after the termination of the Commitments). All rights,
remedies and powers provided in this Guaranty may be exercised, and all waivers
contained in this Guaranty may be enforced, only to the extent that the exercise
or enforcement thereof does not violate any provisions of applicable law which
may not be waived.

                                   ARTICLE VI
                         REPRESENTATIONS AND WARRANTIES

                  To induce the Lenders to enter into this Agreement and to make
the Loans and issue or participate in the Letters of Credit and accept and
purchase Bankers' Acceptances, each Obligor represents and warrants as to itself
and the Bermuda Parent and the U.S. Borrower represent and warrant as to
themselves and the other Obligors (such representations and warranties to
survive any investigation and the making of the Loans and the issuance of any
Letters of Credit and the acceptance and purchase of any Bankers' Acceptances)
to the Lenders and the Agents as follows:

                  SECTION 6.01. Organization and Qualification. Each Obligor and
each Material Subsidiary (a) is a corporation, partnership or entity having
limited liability that is duly organized, validly existing and in good standing
under the laws of the jurisdiction of its incorporation or organization, (b) has
the corporate, partnership or other power and authority to own its property and
to carry on its business as now conducted and (c) is duly qualified as a foreign
corporation to do business and is in good standing in every jurisdiction in
which the failure to be so qualified would, together with all such other
failures of the Obligors and their Subsidiaries, have a Material Adverse Effect.
As of the Execution Date, the corporations and other entities named in Schedule
6.01 are all of the Material Subsidiaries, such Schedule (x) accurately reflects
(i) the direct owner of the Capital Stock of each such Subsidiary and (ii) the
percentage of the issued and outstanding Capital Stock of each such Subsidiary
owned by each Obligor, and (y) accurately sets forth the jurisdictions of their
respective incorporation or organization and jurisdictions in which they are
required to be qualified as foreign corporations, foreign partnerships or other
foreign entities to do business.

                  SECTION 6.02. Authorization, Validity, Etc. Each Obligor has
the corporate, partnership or other power and authority to execute, deliver and
perform its obligations hereunder and under the other Loan Documents to which it
is a party and, in the case of each Borrower, to obtain the Loans, the issuance
of Letters of Credit and the acceptance and purchase of Bankers' Acceptances
hereunder, and all such action has been duly authorized by all necessary
corporate, partnership or other proceedings on its part or on its behalf. This
Agreement has been duly and validly executed and delivered by or on behalf of
each Obligor party hereto and constitutes valid and legally binding agreements
of such Obligor enforceable against such Obligor in accordance with the terms
hereof, and the Notes and the other Loan Documents to which such Obligor is a
party, when duly executed and delivered by or on behalf of such Obligor, will
constitute valid and legally binding obligations of such Obligor enforceable in
accordance with the respective terms thereof and of this Agreement, except, in
each case, (a) as such enforceability may be limited by bankruptcy, insolvency,
reorganization, moratorium, fraudulent transfer or other similar laws relating
to or affecting the enforcement of creditors' rights generally, and by general
principles of equity which may limit the right to obtain equitable remedies
(regardless of whether such enforceability is a proceeding in equity or at law)
and (b)

<PAGE>

as to the enforceability of provisions for indemnification for violation of
applicable securities laws, limitations thereon arising as a matter of law or
public policy.

                  SECTION 6.03. Governmental Consents, Etc. No authorization,
consent, approval, license or exemption of or filing or registration with any
Governmental Authority, is necessary for the valid execution, delivery or
performance by any Obligor of any Loan Document to which it is a party, except
those that have been obtained and such matters relating to performance as would
ordinarily be done in the ordinary course of business after the Execution Date.

                  SECTION 6.04. Conflicting or Adverse Agreements or
Restrictions. Neither the execution, delivery and performance by any Obligor of
the Loan Documents to which it is a party, nor compliance with the terms and
provisions thereof, nor the extensions of credit contemplated by the Loan
Documents, (a) will breach or violate any applicable Requirement of Law, (b)
will result in any breach or violation of, any of the terms, covenants,
conditions or provisions of, or constitute a default under, or result in the
creation or imposition of (or the obligation to create or impose) any Lien upon
any of its property or assets pursuant to the terms of any indenture, mortgage,
deed of trust, agreement or other instrument to which it or any of its
consolidated Subsidiaries is party or by which any property or asset of it or
any of its consolidated Subsidiaries is bound or to which it is subject, except
for breaches, violations and defaults under clauses (a) and (b) that
collectively for all Obligors will not have a Material Adverse Effect or (c)
will violate any provision of the organic documents of any Obligor.

                  SECTION 6.05. Title to Assets. Each Obligor and each
consolidated Subsidiary of the Bermuda Parent has good and indefeasible title to
its assets, except for such defects in title as would not in the aggregate have
a Material Adverse Effect. As of the Effective Date, the property of the Obligor
and their Subsidiaries is subject to no Liens, except Permitted Liens and
immaterial Liens.

                  SECTION 6.06. Litigation. Except for actions, suits or
proceedings described in the filings made by the U.S. Borrower or the Bermuda
Parent with the Securities and Exchange Commission pursuant to the Exchange Act,
as of the Effective Date there are no actions, suits or proceedings pending for
which service of process has been accomplished or, to the best knowledge of any
Obligor, threatened with respect to any Obligor, the Loan Documents or any
transactions contemplated therein that are reasonably likely to have
(individually or collectively) a Material Adverse Effect.

                  SECTION 6.07. Information; Financial Statements. All
information heretofore furnished by the U.S. Borrower and the Bermuda Parent to
the Agents or any Lender in connection with this Agreement, as affected by the
disclosures made herein, in the other Loan Documents and in the filings made by
the U.S. Borrower and the Bermuda Parent with the Securities and Exchange
Commission pursuant to the Exchange Act, did not as of the date thereof and will
not as of the date of the initial Credit Event hereunder, when read together and

                                      -2-
<PAGE>

taken as a whole, 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 any material respect. As of any date prior to the 2002
Merger Date, there has been no material adverse change since December 31, 1997
in the financial condition, business or operations of the U.S. Borrower and its
Subsidiaries taken as a whole which could reasonably be expected to have a
Material Adverse Effect. As of the 2002 Merger Date or any date thereafter,
there has been no material adverse change since the 2002 Merger Date in the
financial condition, business or operations of the Bermuda Parent and its
Subsidiaries taken as a whole which could reasonably be expected to have a
Material Adverse Effect.

                  SECTION 6.08. Investment Company Act. Neither the Bermuda
Parent nor any of its Subsidiaries is, or is regulated as an "investment
company," as such term is defined in the Investment Company Act of 1940, as
amended.

                  SECTION 6.09. Public Utility Holding Company Act. Neither the
Bermuda Parent nor any of its Subsidiaries is a non-exempt "holding company," or
subject to regulation as such, or, to the knowledge of any Obligor's officers,
an "affiliate" 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.

                  SECTION 6.10. ERISA. (a) The U.S. Borrower, and each ERISA
Affiliate has maintained and administered each Plan in compliance with all
applicable laws except for such instances of noncompliance as have not resulted
in and would not reasonably be expected to have a Material Adverse Effect.
Neither the U.S. Borrower nor any ERISA Affiliate has incurred any liability
pursuant to Title I or IV of ERISA or the penalty or excise tax provisions of
the Code relating to employee benefit plans (as defined in Section 3 of ERISA),
and no event, transaction or condition has occurred or exists that would
reasonably be expected to result in the incurrence of any such liability by the
U.S. Borrower or any ERISA Affiliate, or in the imposition of any Lien on any of
the rights, properties or assets of the U.S. Borrower or any ERISA Affiliate
pursuant to Title I or IV of ERISA Sections 401(a)(29) or 412 of the Code, other
than such liabilities or Liens as would in the aggregate reasonably be expected
to have a Material Adverse Effect.

                  (b) No accumulated funding deficiency (as defined in Section
412 of the Code or Section 302 of ERISA), in excess of $25,000,000, whether or
not waived, exists or is expected to be incurred with respect to any Plan.

                  (c) The U.S. Borrower and its ERISA Affiliates have not
incurred withdrawal liabilities (and are not subject to contingent withdrawal
liabilities) under section 4201 or 4204 of ERISA in respect of Multiemployer
Plans that in the aggregate would reasonably be expected to have a Material
Adverse Effect.

                                      -3-
<PAGE>

                  (d) All contributions have been timely made to all employee
benefit plans, as defined in Section 3 of ERISA, except for such failures as
would not reasonably be expected to have a Material Adverse Effect.

                  SECTION 6.11. Tax Returns and Payments. Each Obligor and the
Material Subsidiaries have caused to be filed all federal income tax returns and
other material tax returns, statements and reports (or obtained extensions with
respect thereto) which are required to be filed and have paid or deposited or
made adequate provision in accordance with GAAP for the payment of all taxes
(including estimated taxes shown on such returns, statements and reports) which
are shown to be due pursuant to such returns, except where the failure to pay
such taxes (collectively for the Obligors and the Material Subsidiaries) would
not have a Material Adverse Effect. No material income tax liability of any
Obligor or the Material Subsidiaries has been asserted by the Internal Revenue
Service of the United States or any other Governmental Authority for any taxes
in excess of those already paid, except for taxes which are being contested in
good faith by appropriate proceedings and for which adequate reserves in
accordance with GAAP have been created on the books of the Obligors and their
Subsidiaries.

                  SECTION 6.12. Requirements of Law; Environmental Matters. (a)
The Obligors and each of their consolidated Subsidiaries are in compliance with
all Requirements of Law, applicable statutes, regulations and orders of, and all
applicable restrictions imposed by, all Governmental Authorities in respect of
the conduct of their business and the ownership of their property, except for
such noncompliances which, in the aggregate would not have a Material Adverse
Effect.

                  (b) The U.S. Borrower monitors, in the ordinary course of its
business, the effect of existing Environmental Laws, and each claim asserted
against it, any other Obligor, or any of their Subsidiaries by any Governmental
Authority alleging potential liability or responsibility for violation of any
Environmental Law, on its business operations and properties. As a result
thereof, the U.S. Borrower has reasonably concluded that such Environmental Laws
and any such claims would not, in the aggregate, have a Material Adverse Effect.

                  SECTION 6.13. Purpose of Loans. (a) All proceeds of the Loans
and Bankers' Acceptances will be used by a Borrower for the purposes set forth
in Section 2.08.

                   (b) None of the proceeds of the Loans under the 1998 Chase
Credit Agreement or this Agreement were or will be used directly or indirectly
for the purpose of buying or carrying any "margin stock" within the meaning of
Regulation G or Regulation U (herein called "margin stock") or for the purpose
of reducing or retiring any indebtedness (including the indebtedness repaid with
the proceeds of the loans made under the 1998 Chase Credit Agreement) which was
originally incurred to buy or carry a margin stock, or for any other purpose
which might constitute this transaction a "purpose" credit within the meaning of
Regulation G or Regulation U. Neither any Obligor nor any agent acting on its
behalf has taken or will take any action which might cause this Agreement or any
other Loan Document to violate

                                      -4-
<PAGE>

Regulation G, T, U or X, or any other regulation of the Board or to violate the
Exchange Act. Margin stock did not on the Execution Date, and does not
constitute more than 25% of the assets of the U.S. Borrower or any other
Obligor.

                  SECTION 6.14. Designation of this Agreement and the
Obligations. The Indebtedness evidenced by this Agreement constitutes a
refinancing of the 1996 Chase Credit Agreement which was subsequently refinanced
by the 1998 Chase Credit Agreement. This Agreement constitutes the "principal
bank credit agreement" of the U.S. Borrower, and the Obligations hereunder and
under the other Loan Documents constitute "Designated Senior Indebtedness" as
such phrases are used in the Debenture Indenture.

                  SECTION 6.15. Year 2000 Compliance. The U.S. Borrower has
developed a plan to ensure that the systems of the U.S. Borrower and its
Material Subsidiaries are compliant with the requirements to process
transactions in the year 2000. The U.S. Borrower and its Material Subsidiaries
plan to achieve year 2000 compliance through a combination of upgrading to new
releases of existing software and replacement of existing software with new
fully compliant systems by mid-1999. The expenses and capital expenditures of
the U.S. Borrower and its Material Subsidiaries associated with achieving year
2000 compliance would not reasonably be expected to have a Material Adverse
Effect. The U.S. Borrower and its Material Subsidiaries are currently gathering
information from their key suppliers, vendors and financial institutions
regarding year 2000 compliance.

         reorganization or insolvency would reasonably be expected to have a
         Material Adverse Effect, except that no notice shall be required with

         Affiliate into a defined contribution plan of another ERISA Affiliate.

<PAGE>

                  (i) From time to time and with reasonable promptness, such
other information or documents (financial or otherwise) with respect to the
Bermuda Parent, the U.S. Borrower or any of their Subsidiaries as either Agent
or any Lender through the applicable Agent may reasonably request.

                  SECTION 7.02. Books, Records and Inspections. Each Obligor

Subsidiaries and to discuss the affairs, finances and accounts of any such
entities with a Responsible Officer of each of the Bermuda Parent and the U.S.
Borrower and such Subsidiaries, all at such reasonable times and as often as
such Lender(s), through the applicable Agent, may reasonably request.

                  SECTION 7.05. Existence. Except as expressly permitted

determined that the adoption after the Effective Date or effectiveness after the
Effective Date (whether or not previously announced) of any applicable law,
rule, regulation or treaty regarding capital adequacy, or any change therein
after the Effective Date, or any change in the interpretation or administration
thereof after the Effective Date by any Governmental Authority, central bank or
comparable agency charged with the interpretation or administration thereof, or
compliance by any Lender with any request or directive after the Effective Date
regarding capital adequacy (whether or not having the force of law) of any such
Governmental Authority, central bank or comparable agency has or would have the
effect of reducing the rate of return on such Lender's capital as a consequence
of its obligations hereunder, under the Letters of Credit, the Notes or other
Obligations held by it to a level below that which such Lender could have
achieved but for such adoption, change or compliance (taking into consideration
such Lender's policies with respect to capital adequacy) by an amount deemed by
such Lender to be material, then from time to time, upon satisfaction of the
conditions precedent set forth in this Section, after demand by such Lender
(with a copy to the appropriate Agent) as provided below, pay (subject to
Section 12.18) to such Lender such additional amount or amounts as will
compensate such Lender for such reduction. The certificate of any Lender setting
forth such amount or amounts as shall be necessary to compensate it and the
basis thereof and reasons therefor shall be delivered as soon as practicable to
the U.S. Borrower or the Canadian Borrower, as the case may be, and shall be
presumed correct, absent manifest error. The U.S. Borrower or the Canadian
Borrower, as the case may be, shall pay the amount shown as due on any such
certificate within forty-five (45) Business Days after the delivery of such
certificate. In preparing such certificate, a Lender may employ such assumptions
and allocations of costs and expenses as it shall in good faith deem reasonable
and may use any reasonable averaging and attribution method.

                  SECTION 7.08. Subsidiaries. The Bermuda Parent covenants that
the Subsidiaries identified on Schedule 6.01 are the only Material Subsidiaries
as of the Execution

                                      -4-

Date. Should any Subsidiary, subsequent to the date hereof, become a Material
Subsidiary, the Bermuda Parent shall deliver to the Agents and the Lenders a
revised Schedule 6.01 as provided in Section 7.01(f).

                                                                       EXHIBIT C

                                  ARTICLE VIII
                               NEGATIVE COVENANTS

                  Each of the Bermuda Parent, the U.S. Borrower and the Canadian
Borrower covenants and agrees with the Agents and the Lenders that prior to the
termination of this Agreement it will duly and faithfully perform, and cause its
respective Subsidiaries to perform, each and all of the following covenants:

                  SECTION 8.01. Material Change in Business. The Bermuda Parent
will not, and will not permit its Material Subsidiaries to, engage in any
material business substantially different from those carried on by the U.S.
Borrower and its consolidated Subsidiaries taken as a whole on the date hereof.

                  SECTION 8.02. Consolidation, Merger, Sale or Purchase of
Assets, Etc. The Bermuda Parent will not, and will not permit any other Obligor
to, wind up, liquidate or dissolve its affairs, or effect any merger or
consolidation, and the Bermuda Parent will not, and will not permit any
consolidated Subsidiary to, sell, lease or otherwise dispose of all or
substantially all of its property or assets (other than sales of inventory in
the ordinary course of business) except that this Section 8.02 shall not
prohibit any of the following transactions, or any agreement to effect the same:

                  (a) if, at the time thereof and immediately after giving
effect thereto, no Event of Default or Default shall have occurred and be
continuing, the merger of any other Person with and into the Bermuda Parent or
any of its Subsidiaries, if, (i) in any transaction involving the Bermuda Parent
or the U.S. Borrower, the Bermuda Parent or the U.S. Borrower, as applicable, is
the surviving Person; (ii) in any transaction involving the Canadian Borrower,
the Canadian Borrower is the surviving entity, or (iii) in any other
transaction, a Wholly-Owned Subsidiary is the surviving entity and the Bermuda
Parent, the U.S. Borrower and their Subsidiaries shall be in compliance, on a
pro forma basis after giving effect to such transaction, with the covenants
contained in this Article VIII recomputed as of the last day of the most
recently ended fiscal quarter of the Bermuda Parent, the U.S. Borrower and their
Subsidiaries as if such transaction had occurred on the first day of each
relevant period for testing such compliance, and the U.S. Borrower (with respect
to any merger with a Person not a consolidated Subsidiary of the Bermuda Parent)
shall have delivered to the Agents an officer's certificate to such effect,
together with all relevant financial information and calculations demonstrating
such compliance;

                  (b) transactions and transfers of assets among or between
Obligors and/or Wholly-Owned Subsidiaries or among and between Wholly-Owned
Subsidiaries, in each case, not prohibited by Section 8.07; and

<PAGE>

                  (c) dispositions not otherwise permitted hereunder which are

(ii) the aggregate sales price from such disposition shall be paid in cash or
otherwise on payment terms satisfactory to the applicable Obligor or Subsidiary,
and (iii) the aggregate book value of all assets of the Bermuda Parent and its
Subsidiaries, taken as a whole, shall not be reduced at any time to an amount
which is less than 80% of the aggregate book value of all assets of the U.S.
Borrower, the Canadian Borrower and their Subsidiaries, taken as a whole, on
March 31, 1998, as reflected on the U.S. Borrower's pro forma balance sheet
dated March 31, 1998.

                  SECTION 8.03. Liens. Each of the Bermuda Parent and the
Borrowers will not, and will not permit any of their respective Subsidiaries to,
create, incur, assume or suffer to exist any Lien upon or with respect to any

Obligor or any such Subsidiary whether now owned or hereafter acquired, except
Permitted Liens.

                  SECTION 8.04. Indebtedness. (a) Each of the Bermuda Parent and
the Borrowers will not create, incur or assume, or permit any of their
respective Subsidiaries to create, incur or assume any Indebtedness, unless each
of the Bermuda Parent, the U.S. Borrower and their Subsidiaries shall be in
compliance, on a pro forma basis after giving effect to such transactions, with
the covenants contained in this Article VIII recomputed as of the last day of
the most recently ended fiscal quarter of each of the Bermuda Parent, the U.S.
Borrower and their Subsidiaries as if the transaction in question had occurred
on the first day of each relevant period for testing such compliance.

                  (b) Notwithstanding Section 8.04(a), the aggregate principal
amount of all Indebtedness of all foreign Subsidiaries (other than the Canadian
Borrower) at any time outstanding to any Person other than the U. S. Borrower
and the Subsidiaries shall not exceed 12% of the Bermuda Parent's Net Worth at
such time.

                  SECTION 8.05. Ownership of Obligors. The Bermuda Parent shall
not at any time cease to own, beneficially and of record, directly or
indirectly, 100% of the Capital Stock or other equity interest (except for
directors' qualifying shares) of the U.S. Borrower and U.S. Holdings. The U.S.
Borrower shall not at any time cease to own, beneficially and of record,
directly or indirectly, 100% of the Capital Stock (except for director's
qualifying shares) of the Canadian Borrower.

                  SECTION 8.06. Financial Covenants. (a) The Bermuda Parent will

                  (b) The Bermuda Parent will not permit its Interest Coverage
Ratio at the end of any fiscal quarter to be less than 3.0 to 1.0.

                  SECTION 8.07. Limitation on Transactions with Affiliates. Each
of the Bermuda Parent and the U.S. Borrower will not, and will not permit any of
their consolidated Subsidiaries to, directly or indirectly, conduct any business
or enter into, renew, extend or permit to exist any transaction (including the
purchase, sale, lease or exchange of any assets or the rendering of any service)
or series of related transactions with any Person who is not either (i) a
Borrower or one of the Bermuda Parent's consolidated Subsidiaries or (ii)
Weatherford\Al-Rushaid Limited or Weatherford Saudi Arabia Limited, on terms
that are less favorable to the Bermuda Parent or such consolidated Subsidiary,
as the case may be, than would be available in a comparable arm's length
transaction. Notwithstanding the foregoing, the restrictions set forth in this
covenant will not apply to (i) the payment of reasonable and customary regular
fees to directors of the Bermuda Parent or the U.S. Borrower who are not
employees of the Bermuda Parent or the U.S. Borrower; (ii) loans and advances to
officers, directors and employees of the Bermuda Parent or the U.S. Borrower and
their respective Subsidiaries for travel, entertainment and moving and other
relocation expenses made in direct furtherance and in the ordinary course of
business of the Bermuda Parent, the U.S. Borrower and their respective
Subsidiaries; (iii) any other transaction with any employee, officer or director
of the Bermuda Parent, the U.S. Borrower or any of their respective Subsidiaries
pursuant to employee benefit or compensation arrangements entered into in the
ordinary course of business and approved by, as applicable, the Board of
Directors of the Bermuda Parent, the Board of Directors of the U.S. Borrower, or
the Board of Directors of such Subsidiary permitted by this Agreement; and (iv)
customary underwriting or similar transactions with an investment banking
Affiliate.

                  SECTION 8.08. Restrictions on Subsidiary Dividends. Each of
the Bermuda Parent and the U.S. Borrower will not and will not permit any of its
consolidated Subsidiaries to enter into any agreement or contract which limits
or restricts in any way the payment of any dividends or distributions by any
consolidated Subsidiary of any Obligor to such Obligor or to another
consolidated Subsidiary of such Obligor.

                  SECTION 8.09. Debentures. Except as expressly permitted in
writing by the Majority Lenders, no Obligor will amend, modify or obtain or
grant a waiver of any provision of the Debentures or the Debenture Indenture
with respect to the Debentures if such amendment, modification or waiver would
be adverse to the Lenders.

                  SECTION 8.10. The Debenture Indenture. No Obligor will take
any action that could result in this Agreement failing to be the U.S. Borrower's
"principal bank credit agreement" (as such phrase is used in the Debenture
Indenture).

         agrees to provide such Cover;

                           (iii) require the Canadian Borrower to provide Cover

         and the unpaid accrued interest on the Loans and Reimbursement
         Obligations and all fees and all other amounts payable hereunder, under
         the Notes and under the other Loan Documents to be forthwith due and
         payable, whereupon such amounts shall be and become immediately due and
         payable, without notice (including notice of acceleration and notice of
         intent to accelerate), presentment, demand, protest or other
         formalities of any kind, all of which are hereby expressly waived by
         the U.S. Borrower and the Canadian Borrower; provided, that in the case
         of the occurrence of an Event of Default with respect to any Obligor
         referred to in Section 9.01(f) or Section 9.01(g), the Commitments
         shall be automatically terminated and the principal amount then
         outstanding of and unpaid accrued interest on the Loans and the
         Reimbursement Obligations and all fees and all other amounts payable

         notice (including notice of acceleration and notice of intent to
         accelerate), presentment, demand, protest or other formalities of any
         kind, all of which are hereby expressly waived by the U.S. Borrower and
         the Canadian Borrower;

                           (v) increase the interest rate on all amounts then
         outstanding and the rate of all fees due in respect of Letters of
         Credit to the Past Due Rate; and

                           (vi) exercise any or all other rights and remedies
         available to either Agent or any Lenders under the Loan Documents, at
         law or in equity.

                  SECTION 9.02. Right of Setoff. Upon the occurrence and during
the continuance of any Event of Default, each Lender is hereby authorized at any
time and from time to time, without notice to any Obligor (any such notice being
expressly waived by each Obligor), to setoff and apply any and all deposits
(general or special, time or demand, provisional or final but excluding the
funds held in accounts clearly designated as escrow or trust accounts held by
any Obligor for the benefit of Persons which are not Affiliates of any Obligor),
whether or not such setoff results in any loss of interest or other penalty, and
including without limitation all certificates of deposit, at any time held, and
any other funds or property at any time held, and other indebtedness at any time
owing by such Lender to or for the credit or the account of any Obligor against
any and all of the Obligations irrespective of whether or not such Lender or
either Agent will have made any demand under this Agreement, the Notes or any
other Loan Document. Should the right of any Lender to realize funds in any
manner set forth hereinabove be challenged and any application of such funds be
reversed, whether by court order or

                                      -4-

<PAGE>

otherwise, the Lenders shall make restitution or refund to the applicable
Obligor, as the case may be, pro rata in accordance with their U.S. Commitments
or the Canadian Commitments, as the case may be. Each Lender agrees to promptly
notify the U.S. Borrower, the Canadian Borrower and the Agents after any such
setoff and application, provided that the failure to give such notice will not
affect the validity of such setoff and application. The rights of Agents and the
Lenders under this Section are in addition to other rights and remedies
(including without limitation other rights of setoff) which the Agents or the
Lenders may have. This Section is subject to the terms and provisions of Section
4.05 and Section 12.18. Any amounts realized under this Section 9.02 which
constitute an asset of the Canadian Borrower shall only be applied to the
payment of the Canadian Obligations.

                  SECTION 9.03. Preservation of Security for Unmatured
Obligations. In the event that, following (a) the occurrence of an Event of
Default and the exercise of any rights available to either Agent or any Lender
under the Loan Documents, and (b) payment in full of the principal amount then
outstanding of and the accrued interest on the Loans and Reimbursement
Obligations and fees and all other amounts payable hereunder and under the Loan
Documents and any Letters of Credit or Bankers' Acceptances shall remain
outstanding and undrawn upon, the applicable Agent shall be entitled to hold
(and each Borrower and each other Obligor hereby grants and conveys to each
Agent a security interest in and to) all cash or other proceeds realized or
arising out of the exercise of any rights available under the Loan Documents, at
law or in equity, including, without limitation, the proceeds of any
foreclosure, as collateral for the payment of any amounts due or to become due
under or in respect of such Letters of Credit and/or such Bankers' Acceptances.
Such proceeds shall be held for the ratable benefit of the U.S. Lenders or the
Canadian Lenders, as the case may be. The rights, titles, benefits, privileges,
duties and obligations of the applicable Agent with respect thereto shall be
governed by the terms and provisions of this Agreement. The applicable Agent
may, but shall have no obligation to, invest any such proceeds in such manner as
such Agent, in the exercise of its sole discretion, deems appropriate. Such
proceeds shall be applied to Reimbursement Obligations arising in respect of any
such Letters of Credit, the payment of any Lender's obligations under any such
Letter of Credit and/or the Obligations relating to any such Bankers' Acceptance
when such Letter of Credit is drawn upon or such Bankers' Acceptance matures, as
the case may be. Nothing in this Section shall cause or permit an increase in
the maximum amount of the Obligations permitted to be outstanding from time to
time under this Agreement. Any amounts realized under this Section 9.03 which
constitute an asset of the Canadian Borrower shall only be applied to the
payment of the Canadian Obligations.

                  SECTION 9.04. Other Remedies. No remedy conferred herein or in
any of the other Loan Documents is to be exclusive of any other remedy, and each
and every remedy contained herein or in any other Loan Document shall be
cumulative and shall be in addition to every other remedy given hereunder and
under the other Loan Documents now or hereafter existing at law or in equity or
by statute or otherwise.

                  SECTION 9.05. Currency Conversion After Maturity. At any time
following the occurrence of an Event of Default and the acceleration of the
maturity of the Obligations owed to

                                      -5-
<PAGE>

the Canadian Lenders hereunder, the Canadian Lenders shall be entitled to
convert, with two (2) Business Days' prior notice to the Canadian Borrower, any
and all or any part of the then unpaid and outstanding LIBOR Borrowings and Base
Rate Borrowings of the Canadian Borrower to Canadian Prime Loans. Any such
conversion shall be calculated so that the resulting Canadian Prime Loans shall
be the equivalent on the date of conversion of the amount of Dollars so
converted. Any accrued and unpaid interest denominated in Dollars at the time of
any such conversion shall be similarly converted to Canadian Dollars, and such
Canadian Prime Loans and accrued and unpaid interest thereon shall thereafter
bear interest in accordance with the terms hereof.

                  SECTION 9.06. Application of Moneys During Continuation of
Event of Default. (a) So long as an Event of Default of which the Agent shall
have given notice to the Lenders shall continue, all moneys received by the
Agent (i) from any Obligor under the Loan Documents shall, except as otherwise
required by law, be distributed by the Agent on the dates selected by the Agent
as follows:

                  first, to payment of the unreimbursed expenses for which
                  either Agent or any Lender is to be reimbursed pursuant to
                  Section 13.03 and to any unpaid fees owing to the Agents;

                  second, to the ratable payment of accrued but unpaid interest
                  on the Obligations;

                  third, to the ratable payment of unpaid principal of the
                  Obligations;

                  fourth, to the ratable payment of all other amounts payable by
                  the Obligors hereunder;

                  fifth, to the ratable payment of all other Obligations, until
                  all Obligations shall have been paid in full; and

                  finally, to payment to the Obligors, or their respective
                  successors or assigns, or as a court of competent jurisdiction
                  may direct, of any surplus then remaining from such proceeds.

                  (b) The term "unpaid" as used in this Section 9.06 shall mean
all Obligations outstanding as of any such distribution date (including any
amounts unpaid under clause (v) of the last sentence of Section 9.01) as to
which prior distributions have not been made, after giving effect to any
adjustments which are made pursuant to Section 9.02 of which the Agents shall
have been notified.

                  SECTION 11.01 Guaranty. (a) In consideration of, and in order
to induce (i) the Canadian Lenders to make Canadian Loans to, and to accept and
purchase Bankers' Acceptances from, the Canadian Borrower, (ii) the issuance of
Letters of Credit for the account of any Borrower and (iii) the U.S. Lenders to
make U.S. Loans to the U.S. Borrower, the Guarantors hereby absolutely,
unconditionally and irrevocably guarantee in favor of all of the Lenders, the
punctual payment and performance when due, whether at stated maturity, by
acceleration or otherwise, of the Borrower Obligations and all covenants of the
Borrowers, now or hereafter existing under this Agreement and the other Loan
Documents to which any Borrower is a party, whether for principal, interest
(including interest accruing or becoming owing both prior to and subsequent to
the commencement of any proceeding against or with respect to such Borrower
under any applicable Bankruptcy Code, fees, commissions, expenses (including
reasonable attorneys' fees and expenses) or otherwise (all such obligations
being the "Guaranteed Obligations"). Each of the Guarantors agrees to pay any
and all expenses incurred by each Lender and each Agent in enforcing this
Guaranty against any of the Guarantors.

                  (b) This Guaranty is an absolute, unconditional, present and
continuing guaranty of payment and not of collectibility and is in no way
conditioned upon any attempt to collect from any Obligor or any other action,
occurrence or circumstance whatsoever.

                  SECTION 11.02. Continuing Guaranty. (a) Each Guarantor
guarantees that the Guaranteed Obligations will be paid strictly in accordance
with the terms of this Agreement and the other Loan Documents. Each Guarantor
agrees that, to the maximum extent permitted by applicable law, the Guaranteed
Obligations and Loan Documents to which any Borrower is a party may be extended
or renewed, and indebtedness thereunder repaid and reborrowed in whole or in
part, without notice to or assent by any of the Guarantors, and that each
Guarantor will remain bound upon this Guaranty notwithstanding any extension,
renewal or other alteration of the Guaranteed Obligations or such Loan
Documents, or any repayment and reborrowing of Loans to any Borrower, or the
expiration of the Letters of Credit. The obligations of each Guarantor under
this Guaranty are joint and several and absolute and unconditional irrespective
of the value, genuineness, validity, regularity or enforceability of the
obligations of the other Guarantors under this Agreement or any other Loan
Document or any substitution, release or exchange of any other guarantee of or
security for the Obligations. To the maximum extent permitted by applicable law,
except as otherwise expressly provided in this Agreement or any other Loan
Document to which any Guarantor is a party, the obligations of each Guarantor
under this Guaranty shall be absolute, unconditional and irrevocable, and shall
be performed strictly in accordance with the terms hereof under any
circumstances whatsoever, including:

                  (i) any modification, amendment, supplement, renewal,
      extension for any period, increase, decrease, alteration or rearrangement
      of all or any part of the Guaranteed Obligations, or of this Agreement or
      any other Loan Document executed in connection herewith, or any contract
      or understanding among the Bermuda Parent, U.S. Holdings, U.S.

      that might be granted or given by the Lenders to any Guarantor, any
      Obligor, or any other Person liable on the Guaranteed Obligations;

                  (iii) the insolvency, bankruptcy, arrangement, adjustment,
      composition, liquidation, disability, dissolution or lack of power of any
      Guarantor, the U.S. Borrower, the Canadian Borrower or any other Person at
      any time liable for the payment of all or part of the Guaranteed

      Guaranteed Obligations or any part thereof violate applicable usury laws,
      (E) any Guarantor or any Borrower has valid defenses, claims and offsets

      legally impossible or unenforceable, or (G) this Agreement, any other Loan

                  (v) any full or partial release of the liability of any

      indirectly, jointly, severally, or jointly and severally, to pay, perform,
      guarantee or assure the payment of the Guaranteed Obligations or any part
      thereof; it being recognized, acknowledged and agreed by each Guarantor
      that such Guarantor may be required to pay the Guaranteed Obligations in
      full without assistance or support of any other Person, and that such
      Guarantor has not been induced to enter into this Guaranty on the basis of
      a contemplation, belief, understanding or agreement that any other Person
      will be liable to perform the Guaranteed Obligations, or that any Agent or
      any Lender will look to any other Person to perform the Guaranteed
      Obligations;

<PAGE>

                  (vii) any release, surrender, exchange, subordination,

      security, at any time existing in connection with, or assuring or securing
      payment of, all or any part of the Guaranteed Obligations;

                  (viii) the failure of either Agent, the Lenders or any other
      Person to exercise diligence or reasonable care in the preservation,
      protection, enforcement, sale or other handling or treatment of all or any
      part of such collateral, property or security;

                  (ix) the fact that any collateral, security or Lien
      contemplated or intended to be given, created or granted as security for
      the repayment of the Guaranteed Obligations shall not be properly
      perfected or created, or shall prove to be unenforceable or subordinate to
      any other Lien; it being recognized and agreed by each Guarantor that such
      Guarantor is not entering into this Guaranty in reliance on, or in
      contemplation of the benefits of, the validity, enforceability,
      collectibility or value of any of the collateral for the Guaranteed
      Obligations;

                  (x) any payment by any Borrower or any Guarantor to either
      Agent or any Lender is held to constitute a preference under bankruptcy
      laws, or for any other reason either an Agent or any Lender is required to
      refund such payment or pay such amount to such Borrower, such Guarantor,
      or any other Person; or

                  (xi) any other action taken or omitted to be taken with
      respect to this Agreement, any other Loan Document, the Guaranteed
      Obligations, or the security and collateral therefor, whether or not such
      action or omission prejudices the Guarantors or increases the likelihood
      that the Guarantors will be required to pay the Guaranteed Obligations
      pursuant to the terms hereof;

it being the unambiguous and unequivocal intention of each Guarantor that such
Guarantor shall be obligated to pay the Guaranteed Obligations when due,
notwithstanding any occurrence, circumstance, event, action, or omission
whatsoever, whether contemplated or uncontemplated, and whether or not otherwise
or particularly described herein, except for the full and final payment and
satisfaction of the Guaranteed Obligations after the termination of all of the
Commitments and the expiration or termination of the Letters of Credit.

                  (b) Each Guarantor further agrees that, to the fullest extent
permitted by law, as between any of the Guarantors, on the one hand, and the
Lenders and the Agents, on the other hand, (i) the maturity of the Guaranteed
Obligations may be accelerated as provided in Article IX for the purposes of
this Guaranty, notwithstanding any stay, injunction or other prohibition
preventing such acceleration of the Guaranteed Obligations, and (ii) in the
event of any acceleration of the Guaranteed Obligations as provided in Article
IX, the Guaranteed Obligations (whether or not due and payable) shall forthwith
become due and payable by the Guarantors for the purpose of this Guaranty.

                  SECTION 11.03. Effect of Debtor Relief Laws. If after receipt
of any payment of, or proceeds of any security applied (or intended to be
applied) to the payment of all or any part of the Guaranteed Obligations, either
Agent, the applicable Issuer or any Lender is for any

                                      -3-
<PAGE>

reason compelled to surrender or voluntarily surrenders, such payment or
proceeds to any Person (a) because such payment or application of proceeds is or
may be avoided, invalidated, declared fraudulent, set aside, determined to be
void or voidable as a preference, fraudulent conveyance, fraudulent transfer,
impermissible set-off or a diversion of trust funds or (b) for any other reason,
including (i) any judgment, decree or order of any court or administrative body
having jurisdiction over either Agent, the applicable Issuer, any Lender or any
of their respective properties or (ii) any settlement or compromise of any such
claim effected by either Agent, the Issuer of any Letters of Credit or any
Lender with any such claimant (including any of the Borrowers), then the
Guaranteed Obligations or part thereof intended to be satisfied shall be
reinstated and continue, and this Guaranty shall continue in full force as if
such payment or proceeds have not been received, notwithstanding any revocation
thereof or the cancellation of any instrument evidencing any of the Guaranteed
Obligations or otherwise; and each Guarantor shall be liable to pay the Agents,
the Issuer of any Letters of Credit and the Lenders, and hereby do indemnify the
Agents, the Issuer of any Letters of Credit and the Lenders and hold them
harmless for the amount of such payment or proceeds so surrendered and all
reasonable expenses (including reasonable attorneys' fees, court costs and
expenses attributable thereto) incurred by either Agent, such Issuer or any such
Lender in the defense of any claim made against it that any payment or proceeds
received by the such Agent, such Issuer or any such Lender in respect of all or
part of the Guaranteed Obligations must be surrendered. The provisions of this
paragraph shall survive the termination of this Guaranty, and any satisfaction
and discharge of any Borrower by virtue of any payment, court order or any law.

                  SECTION 11.04. Waiver. Each Guarantor hereby waives
promptness, diligence, notice of acceptance and any other notice with respect to
any of the Guaranteed Obligations and this Guaranty and waives presentment,
demand for payment, notice of intent to accelerate, notice of dishonor or
nonpayment and any requirement that either Agent or any Lender institute suit,
collection proceedings or take any other action to collect the Guaranteed
Obligations, including any requirement that either Agent or any Lender protect,
secure, perfect or insure any Lien against any property subject thereto or
exhaust any right or take any action against any Borrower or any other Person or
any collateral (it being the intention of the Agents, the Lenders and the
Guarantors that this Guaranty is to be a guaranty of payment and not of
collection). It shall not be necessary for either Agent or any Lender, in order
to enforce any payment by any Guarantor hereunder, to institute suit or exhaust
its rights and remedies against any other Guarantor, any Borrower or any other
Person, including others liable to pay the Guaranteed Obligations, or to enforce
its rights against any security ever given to secure payment thereof. Each
Guarantor hereby expressly waives to the maximum extent permitted by applicable
law each and every right to which it may be entitled by virtue of the suretyship
laws of the State of Texas or any other state in which it may be located,
including any and all rights it may have pursuant to Rule 31, Texas Rules of
Civil Procedure, Section 17.001 of the Texas Civil Practice and Remedies Code
and Chapter 34 of the Texas Business and Commerce Code. Each Guarantor hereby
waives marshaling of assets and liabilities, notice by either Agent or any
Lender of any indebtedness or liability to which such Lender applies or may
apply any amounts received by such Lender, and of the creation, advancement,
increase, existence, extension, renewal, rearrangement or modification of the
Guaranteed Obligations. Each Guarantor expressly waives, to the extent permitted
by applicable law, the benefit of any and all laws providing for exemption of
property from execution or for valuation and appraisal upon foreclosure.

                  SECTION 11.05. Full Force and Effect. This Guaranty is a
continuing guaranty and shall remain in full force and effect until all of the
Guaranteed Obligations under this Agreement and the other Loan Documents to
which any Borrower is a party and all other amounts payable under this Guaranty
have been paid in full (after the termination of the Commitments and the
termination or expiration of the Letters of Credit). All rights, remedies and
powers provided in this Guaranty may be exercised, and all waivers contained in
this Guaranty may be enforced, only to the extent that the exercise or
enforcement thereof does not violate any provisions of applicable law which may
not be waived.
